500 Million Years of Fish Evolution

500 Million Years of Fish Evolution Compared to dinosaurs, mammoths and saber-toothed cats, fish evolution may not seem all that interesting - until you realize that if it werent for prehistoric fish, dinosaurs, mammoths, and saber-toothed cats would never have existed. The first vertebrates on the planet, fish provided the basic body plan subsequently elaborated on by hundreds of millions of years of evolution: in other words, your great-great-great (multiply by a billion) grandmother was a small, meek fish of the Devonian period. (See a gallery of prehistoric fish pictures and profiles, a list of 10 recently extinct fish, and a slideshow of 10 Prehistoric Fish Everyone Should Know.) The Earliest Vertebrates: Pikaia and Pals Although most paleontologists wouldnt recognize them as true fish, the first fish-like creatures to leave an impression on the fossil record appeared during the middle Cambrian period, about 530 million years ago. The most famous of these, Pikaia, looked more like a worm than a fish, but it had four features crucial to later fish (and vertebrate) evolution: a head distinct from its tail, bilateral symmetry (the left side of its body looked like the right side), V-shaped muscles, and most importantly, a nerve cord running down the length of its body. Because this cord wasnt protected by a tube of bone or cartilage, Pikaia was technically a chordate rather than a vertebrate, but it still lay at the root of the vertebrate family tree. Two other Cambrian proto-fish were a bit more robust than Pikaia. Haikouichthys is considered by some expertsat least those not overly concerned by its lack of a calcified backbone - to be the earliest jawless fish, and this inch-long creature had rudimentary fins running along the top and bottom of its body. The similar Myllokunmingia was slightly less elongated than either Pikaia or Haikouichthys, and it also had pouched gills and (possibly) a skull made of cartilage. (Other fish-like creatures may have predated these three genera by tens of millions of years; unfortunately, they havent left any fossil remains.) The Evolution of Jawless Fish During the Ordovician and Silurian periods - from 490 to 410 million years ago - the worlds oceans, lakes, and rivers were dominated by jawless fish, so named because they lacked lower jaws (and thus the ability to consume large prey). You can recognize most of these prehistoric fish by the -aspis (the Greek word for shield) in the second parts of their names, which hints at the second main characteristic of these early vertebrates: their heads were covered by tough plates of bony armor. The most notable jawless fish of the Ordovician period were Astraspis and Arandaspis, six-inch-long, big-headed, finless fish that resembled giant tadpoles. Both of these species made their living by bottom-feeding in shallow waters, wriggling slowly above the surface and sucking up tiny animals and the waste of other marine creatures. Their Silurian descendants shared the same body plan, with the important addition of forked tail fins, which gave them more maneuverability. If the -aspis fish were the most advanced vertebrates of their time, why were their heads covered in bulky, un-hydrodynamic armor? The answer is that, hundreds of millions of years ago, vertebrates were far from the dominant life forms in the earths oceans, and these early fish needed a means of defense against giant sea scorpions and other large arthropods. The Big Split: Lobe-Finned Fish, Ray-Finned Fish, and Placoderms By the start of the Devonian periodabout 420 million years agothe evolution of prehistoric fish veered off in two (or three, depending on how you count them) directions. One development, which wound up going nowhere, was the appearance of the jawed fishes known as placoderms (plated skin), the earliest identified example of which is Entelognathus. These were essentially larger, more varied -aspis fish with true jaws, and the most famous genus by far was the 30-foot-long Dunkleosteus, one of the biggest fish that ever lived. Perhaps because they were so slow and awkward, placoderms vanished by the end of the Devonian period, outclassed by two other newly evolved families of jawed fish: the chondrichthians (fish with cartilaginous skeletons) and osteichthyans (fish with bony skeletons). The chondrichthians included prehistoric sharks, which went on to tear their own bloody path through evolutionary history. The osteichthyans, meanwhile, split into two further groups: the actinopterygians (ray-finned fish) and sarcopterygians (lobe-finned fish). Ray-finned fish, lobe-finned fish, who cares? Well, you do: the lobe-finned fishes of the Devonian period, such as Panderichthys and Eusthenopteron, had a characteristic fin structure that enabled them to evolve into the first tetrapods - the proverbial fish out of water ancestral to all land-living vertebrates, including humans. The ray-finned fish stayed in the water, but went on to become the most successful vertebrates of all: today, there are tens of thousand of species of ray-finned fish, making them the most diverse and numerous vertebrates on the planet (among the earliest ray-finned fish were Saurichthys and Cheirolepis). The Giant Fish of the Mesozoic Era No history of fish would be complete without mentioning the giant dino-fish of the Triassic, Jurassic and Cretaceous periods (though these fish werent as numerous as their oversized dinosaur cousins). The most famous of these giants were the Jurassic Leedsichthys, which some reconstructions put at a whopping 70 feet long, and the Cretaceous Xiphactinus, which was only about 20 feet long but at least had a more robust diet (other fish, compared to Leedsichthys diet of plankton and krill). A new addition is Bonnerichthys, yet another large, Cretaceous fish with a tiny, protozoan diet. Bear in mind, though, that for every dino-fish like Leedsichthys there are a dozen smaller prehistoric fish of equal interest to paleontologists. The list is nearly endless, but examples include Dipterus (an ancient lungfish), Enchodus (also known as the saber-toothed herring), the prehistoric rabbitfish Ischyodus, and the small but prolific Knightia, which has yielded so many fossils that you can buy your own for less than a hundred bucks.

Niccolò Machiavelli - His Life, Philosophy and Influence

Niccolà ² Machiavelli - His Life, Philosophy and Influence Niccolà ² Machiavelli was one of the most influential political theorists of Western philosophy. His most read treatise, The Prince, turned Aristotle’s theory of virtues upside down, shaking the European conception of government at its foundations. Machiavelli lived in or nearby Florence Tuscany his whole life, during the peak of the Renaissance movement, in which he took part. He is also the author of a number of additional political treatises, including The Discourses on the First Decade of Titus Livius, as well as of literary texts, including two comedies and several poems. Life Machiavelli was born and raised in Florence, Italy, where his father was an attorney. Historians believe his education was of exceptional quality, especially in grammar, rhetoric, and Latin. He seems not to have been instructed in Greek, though, despite Florence having been a major center for the study of the Hellenic language since the middle of the fourteen hundreds. In 1498, at age twenty-nine Machiavelli was called to cover two relevant governmental roles in a moment of social turmoil for the newly constituted Republic of Florence: he was named chair of the second chancery and – a short time after – secretary of the Dieci di Libert e di Pace, a ten-person council responsible for maintaining diplomatic relationships with other States. Between 1499 and 1512 Machiavelli witnessed first-hand the unfolding of Italian political events. In 1513, the Medici family returned to Florence. Machiavelli was arrested on suspicion of conspiracy to overthrow this powerful family. He was first imprisoned and tortured then sent into exile. After his release, he retired to his country house in San Casciano Val di Pesa, about ten miles southwest of Florence. It is here, between 1513 and 1527, that he wrote his masterpieces. The Prince De Principatibus (literally: On Princedoms) was the first work composed by Machiavelli in San Casciano mostly during 1513; it was published only posthumously in 1532. The Prince is a short treatise of twenty-six chapters in which Machiavelli instructs a young pupil of the Medici family on how to acquire and maintain political power. Famously centered on the right balancing of fortune and virtue in the prince, it is by far the most read work by Machiavelli and one of the most prominent texts of Western political thought. The Discourses Despite the popularity of The Prince, Machiavelli’s major political work is probably The Discourses on the First Decade of Titus Livius. Its first pages were written in 1513, but the text was completed only between 1518 and 1521. If The Prince instructed how to govern a princedom, The Discourses were meant to educate future generations to achieve and maintain political stability in a republic. As the title suggests, the text is structured as a free commentary on the first ten volumes of Ab Urbe Condita Libri, the major work of Roman historian Titus Livius (59B.C.-17A.D.) The Discourses are divided into three volumes: the first devoted to internal politics; the second to foreign politics; the third one to a comparison of the most exemplary deeds of individual men in ancient Rome and Renaissance Italy. If the first volume reveals Machiavelli’s sympathy for the republican form of government, it is especially in the third that we find a lucid and pungent critical gaze at the political situation of Renaissance Italy. Other Political and Historical Works While carrying forward his governmental roles, Machiavelli had the opportunity to write about the events and issues he was witnessing first-hand. Some of them are critical to understanding the unfolding of his thought. They range from the examination of the political situation in Pisa (1499) and in Germany (1508-1512) to the method used by the Valentino in killing his enemies (1502). While in San Casciano, Machiavelli wrote also a number of treatises on politics and history, including a treatise on war (1519-1520), a recount of the life of the condottiero Castruccio Castracani (1281-1328), a history of Florence (1520-1525). Literary Works Machiavelli was a fine writer. He left us two fresh and entertaining comedies, The Mandragola (1518) and The Clizia (1525), both of which are still represented in these days. To these we shall add a novel, Belfagor Arcidiavolo (1515); a poem in verses inspired to Lucius Apuleius’s (about 125-180 A.D.) major work, L’asino d’oro (1517); several more poems, some of which amusing, the translation of a classical comedy by Publius Terentius Afer (circa 195-159B.C.); and several other smaller works. Machiavellianism By the end of the sixteenth century, The Prince had been translated into all major European languages and was the subject of heated disputes into the most important courts of the Old Continent. Often misinterpreted, the core ideas of Machiavelli were so despised that a term was coined to refer to them: ​Machiavellianism. To these days the term indicates a cynical attitude, according to which a politician is justified to do any tort if the end requires it.

Analysis of the integrated marketing communications mix strategies of Essay

Analysis of the integrated marketing communications mix strategies of your chosen smartphone brand - Essay Example With the help of analysis it is noted that Apple Inc. delivered attractive and best quality product designed for a finest price. Integrated marketing communication (IMC) mix is a process, designed for managing the consumer relationships that drive product value. More exclusively, it is defined as cross functional practice for generating and nourishing beneficial relationship with the customers and stakeholders (Koekemoer, 2004). Now the environment of marketing communication is changing: mass markets have been fragmented, thereby, causing marketers to move from mass selling to segment marketing; and shifting from mass media towards focused media. Integrated marketing communication activities entail a forward flow of communications. Producers communicate to the wholesaler, the retailer, and the end consumer. Resellers correspond to customers. Backward communication flow also exists but is crucial to understand markets and customers (Anderson and Vincze, 2006). The main aim of this report is to analyse the integrated marketing communication mix strategies of Apple Inc. The main elements of communication procedure are the sender, encoding message, receiver, medium, decoding, and feedback. A clear understanding of all these elements helps to design an effective communication programs (Jacobson, 1999). Sender: Sender is a person who starts the communication process by thinking about the idea to have a conversation with the receiver. During the communication, the body language, vocabulary and the voice tone of the speaker influence how the receiver accepts the message (Jacobson, 1999). Encoding: It is an act of creating an idea reachable to the entire mass. Before the message or an idea could be conveyed to receiver or the people, the sender requires encoding the message in a suitable code (Cleary, 2004). Medium: Once the idea of sender are translated or encoded, they are conveyed in the structure of message. Messages could

Significance Testing Essay Example | Topics and Well Written Essays - 1500 words

Significance Testing - Essay Example A research project always has the goal to investigate the causes and the reasons and thereby to be able to draw the conclusion in the basis of the changes that take place. Responses that have been counted in this vase are the independent or the dependent variables or the predictors (Park, 2005). In statistics sampling is referred to as the selection of a portion of the population whereas this is the sample that represents the major part of the population. Sampling types in this case include the convenience, accidental, quota sample, random sampling as well as the cluster sampling. In this case it has to be seen as to what the margin of error is in the specific sampling technique. Main problems that are faced in this case is the sample bias where the sample is not the representative of the whole population thereby the sample has to be chosen rather carefully. Importance that has been used in the statistical testing is that in the research projects it can be used to test the data in the experimental basis, so as to draw the conclusion that are based on the facts representing the major part of the population. ... Statistical hypothesis testing has been considered to be one of the main techniques in the frequentist statistical inference, and still it has been seen that this is the technique that has been under criticism. An important role is played by the statistical hypotheses testing in statistical inferences. It has been said by statisticians that the hypothesis testing although has many shortcomings and still there are many changes that are needed but it is the technique that plays central role in theory as well as the practice of statistics (Levin, 1998). When the null hypothesis are being tested than the main point that has to be taken into account is the effect size. As it has been known that here are four main parts of the statistical answers and they are inclusive of the effect size, the sample size, the alpha level that indicates the significance level of the newer or the odds that have been observed by the answer by the significance testing and the last one being the power that indicates the odds that have been observed by the reader of the research results. It has been estimated that tout of these for components there are some components that can be manipulated and this all depends upon the situation and the circumstances in which the research of the project has been carried out. The main point that needs pt be argued here in this case that the null hypothesis is known as the null hypotheses as it has the no difference or no effect case. The main statistical technique that has been facing the discussion hitherto by the professors, the researchers is the significance test. It has changed its face into a controversy from being just the topic of discussion these days. Since many years

Class Divided Essay Example for Free

Class Divided Essay When I first read the title a Class Divided; the first thought that came to my mind was another story about Blacks and Whites being separated. I really had no idea that what I was about to see and read would be a learning lesson like one I had never had before. But to my surprise once I started reading the article One Friday in April 1968 I knew that this was going to be different then any thing I had read. So I allowed myself to fill what the writer was writing to try and fill what Jane Elliott had felt that day in April in 1968. As she prepared to face a group of 3rd grade students who happened, to be white and teach them about racism and discrimination something she hoped they would understand the rest of their lives. Jane Elliott had taught her class about what the two things had mint before but not on the level she had planed to go to today; she hoped that with what she was planning to do would not mean she had crossed the line to far, but if not her then who and if not then when. It was not something that Jane Elliott could put off any longer. With the assassination of Rev Martin Luther King the night before this assignment was sure not to be an easy task. Jane Elliott knew things would be different in class this morning! But she was a women who knew in her heart what task laid before her and not quite sure how the outcome would be, or how or what response the children or their parents may have it was to late too turn around now. This was a situation that was going on all over the world not just in her town or in America. And it was time that someone brought right to the face of Americans children I mean who is the leaders of tomorrow but the children of today. And they might as well get a taste of the real world now; really what could the worst that could happen? You might find out that even at that young age, some of them might even understand that racism and discrimination is something they never want to be a part of or on the flip side you would have a bunch of racists’ running around; it was best to know now what kind of people were being raised instead of finding out later when they get to old to even change. The technique that Jane Elliott used was very different then any I had heard about and since by the video I knew there where no blacks in her class to see how she would divide the class I was very interested. And here white women a teacher from a rule town was willing to put and idea a solution of an age old question of how to stop discrimination. Something the nation had no solution to and countries and people were battling over everyday. How was this demonstration with kids going to change anything? Jane Elliott took a chance not just for wanting to teach students about racism and discrimination but teach it in a manner in which you as a person could actually feel acknowledge and understand the experience that they just went through to know how it feels to walk in another man shoes. Jane wanted her students to understand that at the end of the day no one is superior or inferior to anyone else no matter what your status is in life. Now I admit I had no idea how she was going to approach this difficult task and get the point across but as I continued to watch on, it was becoming clearer. When Jane Elliott started her class the following morning it started off I guess you could say any normal class day would start the students seem to be as happy as the average 3rd grader would be. The normal inquisitive minds of most kids; as the kids hung up there coast and put away their coat and lunches away she started getting the kids in order and as class started she asked them a question like did they know what were some of the things that made other people different from themselves and other whites. Some said size one said clothes but color was the one they all could agree on and so she asked them what where some of the skin colors that where different then their own? Blacks and sometimes they were called Negros and Indians. So she asked the kids and how did they think that people of other colors felt by feeling different about being different they said they felt that blacks did not feel as smart by not being white, and they felt stupid because they were black. And so with that she asked them how they would fill if they were treated different because of their color! Now keep in mind this is the week of national Brotherhood and you are suppose to treat your fellow mates with respect and love show them you care because they are your brother. And Jane Elliott was about to do just the opposite. She asked them how would they fill if they where treated different because of the color they where now at first I’m thinking how is this going too work they are all white. But she told them that she was going to divide them up by the color of their eyes. Now for that day all people with blue eyes were going to be better then the brown eyes and it was like immediately you seen a whole different reaction from the class, it was if these weren’t even the same kids the brown eyed kids started to withdraw almost immediately and the blue eyes were in full bloom. Some of the blue eyed kids even gave a solution on how Ms Jane should handle the brown eyed kids with a yard stick incase they got out of hand. Now by lunch time the blue eyes felt on top of the world they told not to play with brown eyed kids and that they could have seconds on food the brown kids could not. Now for the brown eyes you could see the confusion on their faces the hurt they actually tried to rationalize how the same kids they had been friends with and played with change so much. And I remembered thinking how could in such a short period of time could these sweet kids turn into the ill monsters they has become. For me it was like if it took them such little time to embrace such a cruel sprite then I knew how it must be for grown people who exercise this kind of behavior for a long period of time how bitter and angry they must be not at the world but themselves. Now one of the scenes on the playground when the blue eyed boy taunts the brown eyed boys and they get into the brawl it hurt because before this experiment they were friends. And just in a couple of hours all there upbringing and brotherly love had went out the window. Now when Jane asked the boys what happen the blue eyed boy said it made him fill powerful and in charge? He said it made him fill like a king. The brown eyed boy to me on the hand seemed to be more affected by what had happen at lunch he said he was hurt and they use to be friends that the eyes had nothing to do with it they had been friends and even though he hit the blue eyed boy it did not make him fill better. This made me see that even though this was the first time they had put a division among the students the lust for power emerged quickly in some with out hesitation and others went along with it because that’s what they were told to do while again the brown eyed boy stood up for himself regardless of what the teacher said even though he admitted that he did not like being treated different and fighting did not make it better he just knew it was not fair. On returning back to class Ms Jane also noticed how the blue eyed kids were getting there work done faster and even being more helpful she noticed how the brown eyed kids looked like they where helpless and not really participating in class time you tell they felt rejected. It was as if had caught the essence of creating a bad situation but had the answer for straitening it out all was not lost. Jane announced to the that the roles had changed the following morning in class and believe me the blue eyes where not to happy with the change this mint they would be on the bottom and the brown eyes were on top. Some kids did not want to do it anymore while others could not wait to be on top. What this showed me with kids is that they do as they see being done just as well as what they hear. When it was time to go back to being normal no more blue eyes no more brown eyes over all the kids seemed to be happy to return to the normal class setting; she allowed the kids to tell what they like and disliked better about it and in the end the all promised not to ever dislike somebody because of there skin color. When Jane Elliott did this same experiment in the jail there was a whole different reaction here the video was showed to the inmates not as a test but more as a teaching tool which I kind of understood discrimination is something that most of the prisoners had encountered some where along the way either in there or one of the reasons they where in jail in the first place. But she did use the correctional officers and parole agents and I could not believe what was going on one man early on caught on that it must have been some kind of test because he notice the obvious brown eyes only signs blue eyes only signs seating situation while others tried very heard but it was this one lady she was a blue eye and a correctional officer she questioned and taunted everything that Jane wanted them to do prior to the blue eyes meeting in the room with the brown eyed people she sort told them that the group of people entering were going to be rude loud dominant and disruptive once the seminar bega n. No one knew what was going on but she was setting the blue eye people to fail. She made them annoyed in every way possible so about time the group was together it would seem that the blue eyed people were just as she described. Now the Lady with the blue eyes seemed to be the type of person that was easily irritated to start with her whole persona was if she was in charge and not Jane she answered questions with questions kept getting smart like she was going to be in charge no matter what it was her life and job were one in one and nobody was going to make her fill less she controlled the inmates at work and that was how her personality came off as if she did not come second to anyone things went her way or no way and that there is only one right answer hers; she became very annoying too me and she made me fill like some people In authority position now like its only their way that works does on like individuality love making people fill less in order for them to feel good about the mselves. It seems if the other blue eyed people were willing to try and work out was being taught she kept a defensive block up all the time. Her behavior had begun to annoyed a lot of the people in the room including some blue eyes This also made me see how much easier it was for the children to grasp what was being taught; more then the adults the kids were willing to say that how they were able to treat people even when they were told to do so if it mint treating them bad they did not like it. Of course for the one kid who felt like it gave him power. The correctional officer Acted, as if to admit that you are not better then the person next to you then there better then you. I think she had control issues; me, personally fill that you can learn something new ever day if you are willing to learn you have good and bad I every race good and bad comes in many shapes and sizes. But if you be the best you can be treat people with kindness and respect you will get treated the same. As long as you know there are exceptions to all rules and some people are just not nice no matter what. But don’t let that change who you are. Smile and somebody bound to smile back.

Macbeth Tragedy :: essays research papers

Shakespeare may have written Macbeth two hundred years ago with a fine tipped feather pen to make a living. However, his intentions have been drastically blown out of the realm of classic drama. Critics come up with new wonders all the time questioning the true tragedy of Shakespeare’s Macbeth. Was it a Tragedy or not? Who’s to answer the question except Shakespeare himself who due to the human life expectancy of eighty years cannot clarify it. We can only base our opinion on the great Aristotle’s definition of Tragedy. He basically said that you must feel pity for the hero to make his death tragic in this context of Tragedy.   Ã‚  Ã‚  Ã‚  Ã‚  I can completely understand where some people could see Macbeth as a tragedy and argue the exact opposite of me. Macbeth started out as a pretty nice guy and seemed to have everyone on his side. He had a great wife who loved him very much and a beautiful home, what more could a guy ask for. He was brave, strong and handsome. He was also part of the one of strongest nations in that part of the world at that time. His taunting ambition and gullibility had a terrible effect on his action. His loving wife, whom he trusted and cared for very much had something to do with the murder of too. His wife had a heavy hand on his thoughts and could manipulate him with ungodly ease. She tested Macbeths manhood and determination by questioning his integrity, and as all men know that is almost impossible to negate.   Ã‚  Ã‚  Ã‚  Ã‚  Then there was the witches, whose ability to fool with the minds of men almost killed the king themselves. Macbeth was gullible and those witches took advantage of that weakness quite well. They told him exactly what was needed to drive him right into action. The combination of the witches, Lady Macbeth and his blinding ambition was obviously enough to make him kill not only his majesty but also his friend. Those are all good points and like I said I understand why some people could feel bad for him and call the play a tragedy.   Ã‚  Ã‚  Ã‚  Ã‚  Well I don’t. How could I feel bad for someone who completely dictated his fate? I could care less how gullible or ambitious he was and quite frankly I think his death was a relief. At least since he died he couldn’t commit any more bloodshed or crush any more people’s lives.

The Twilight Saga 2: New Moon Chapter 24 VOTE

HE WAS NOT PLEASED, THAT MUCH WAS EASY TO READ in his face. But, without further argument, he took me in his arms and sprang lithely from my window, landing without the slightest jolt, like a cat. It was a little bit farther down than I'd imagined. â€Å"All right then,† he said, his voice seething with disapproval. â€Å"Up you go.† He helped me onto his back, and took off running. Even after all this time, it felt routine. Easy. Evidently this was something you never forgot, like riding a bicycle. It was so very quiet and dark as he ran through the forest, his breathing slow and evendark enough that the trees flying past us were nearly invisible, and only the rush of air in my face truly gave away our speed. The air was damp; it didn't burn my eyes the way the wind in the big plaza had, and that was comforting. As was the night, too, after that terrifying brightness. Like the thick quilt I'd played under as a child, the dark felt familiar and protecting. I remembered that running through the forest like this used to frighten me, that I used to have to close my eyes. It seemed a silly reaction to me now. I kept my eyes wide, my chin resting on his shoulder, my cheek against his neck. The speed was exhilarating. A hundred times better than the motorcycle. I turned my face toward him and pressed my lips into the cold stone skin of his neck. â€Å"Thank you,† he said, as the vague, black shapes of trees raced past us. â€Å"Does that mean you've decided you're awake?† I laughed. The sound was easy, natural, effortless. It sounded right. â€Å"Not really. More that, either way, I'm not trying to wake up. Not tonight.† â€Å"I'll earn your trust back somehow,† he murmured, mostly to himself. â€Å"If it's my final act.† â€Å"I trust you,† I assured him. â€Å"It's me I don't trust.† â€Å"Explain that, please.† He'd slowed to a walkI could only tell because the wind ceasedand I guessed that we weren't far from the house. In fact, I thought I could make out the sound of the river rushing somewhere close by in the darkness. â€Å"Well† I struggled to find the right way to phrase it. â€Å"I don't trust myself to be enough. To deserve you. There's nothing about me that could hold you.† He stopped and reached around to pull me from his back. His gentle hands did not release me; after he'd set me on my feet again, he wrapped his arms tightly around me, hugging me to his chest. â€Å"Your hold is permanent and unbreakable,† he whispered. â€Å"Never doubt that.† But how could I not? â€Å"You never did tell me† he murmured. â€Å"What?† â€Å"What your greatest problem is.† â€Å"I'll give you one guess.† I sighed, and reached up to touch the tip of his nose with my index finger. He nodded. â€Å"I'm worse than the Volturi,† he said grimly. â€Å"I guess I've earned that.† I rolled my eyes. â€Å"The worst the Volturi can do is kill me.† He waited with tense eyes. â€Å"You can leave me,† I explained. â€Å"The Volturi, Victoria they're nothing compared to that.† Even in the darkness, I could see the anguish twist his faceit reminded me of his expression under Jane's torturing gaze; I felt sick, and regretted speaking the truth. â€Å"Don't,† I whispered, touching his face. â€Å"Don't be sad.† He pulled one corner of his mouth up halfheartedly, but the expression didn't touch his eyes. â€Å"If there was only some way to make you see that I can't leave you,† he whispered. â€Å"Time, I suppose, will be the way to convince you.† I liked the idea of time. â€Å"Okay,† I agreed. His face was still tormented. I tried to distract him with inconsequentials. â€Å"Sosince you're staying. Can I have my stuff back?† I asked, making my tone as light as I could manage. My attempt worked, to an extent: he laughed. But his eyes retained the misery. â€Å"Your things were never gone,† he told me. â€Å"I knew it was wrong, since I promised you peace without reminders. It was stupid and childish, but I wanted to leave something of myself with you. The CD, the pictures, the ticketsthey're all under your floorboards.† â€Å"Really?† He nodded, seeming slightly cheered by my obvious pleasure in this trivial fact. It wasn't enough to heal the pain in his face completely. â€Å"I think,† I said slowly, â€Å"I'm not sure, but I wonder I think maybe I knew it the whole time.† â€Å"What did you know?† I only wanted to take away the agony in his eyes, but as I spoke the words, they sounded truer than I expected they would. â€Å"Some part of me, my subconscious maybe, never stopped believing that you still cared whether I lived or died. That's probably why I was hearing the voices.† There was a very deep silence for a moment. â€Å"Voices?† he asked flatly. â€Å"Well, just one voice. Yours. It's a long story.† The wary look on his face made me wish that I hadn't brought that up. Would he think I was crazy, like everyone else? Was everyone else right about that? But at least that expressionthe one that made him look like something was burning himfaded. â€Å"I've got time.† His voice was unnaturally even. â€Å"It's pretty pathetic.† He waited. I wasn't sure how to explain. â€Å"Do you remember what Alice said about extreme sports?† He spoke the words without inflection or emphasis. â€Å"You jumped off a cliff for fun.† â€Å"Er, right. And before that, with the motorcycle† â€Å"Motorcycle?† he asked. I knew his voice well enough to hear something brewing behind the calm. â€Å"I guess I didn't tell Alice about that part.† â€Å"No.† â€Å"Well, about that See, I found that when I was doing something dangerous or stupid I could remember you more clearly,† I confessed, feeling completely mental. â€Å"I could remember how your voice sounded when you were angry. I could hear it, like you were standing right there next to me. Mostly I tried not to think about you, but this didn't hurt so muchit was like you were protecting me again. Like you didn't want me to be hurt. â€Å"And, well, I wonder if the reason I could hear you so clearly was because, underneath it all. I always knew that you hadn't stopped loving me.† Again, as I spoke, the words brought with them a sense of conviction. Of rightness. Some deep place inside me recognized truth. His words came out half-strangled. â€Å"You were risking your life to hear† â€Å"Shh,† I interrupted him. â€Å"Hold on a second. I think I'm having an epiphany here.† I thought of that night in Port Angeles when I'd had my first delusion. I'd come up with two options. Insanity or wish fulfillment. I'd seen no third option. But what if What if you sincerely believed something was true, but you were dead wrong? What if you were so stubbornly sure that you were right, that you wouldn't even consider the truth? Would the truth be silenced, or would it try to break through? Option three: Edward loved me. The bond forged between us was not one that could be broken by absence, distance, or time. And no matter how much more special or beautiful or brilliant or perfect than me he might be, he was as irreversibly altered as I was. As I would always belong to him, so would he always be mine. Was that what I'd been trying to tell myself? â€Å"Oh!† â€Å"Bella?† â€Å"Oh. Okay. I see.† â€Å"Your epiphany?† he asked, his voice uneven and strained. â€Å"You love me,† I marveled. The sense of conviction and Tightness washed through me again. Though his eyes were still anxious, the crooked smile I loved best flashed across his face. â€Å"Truly, I do.† My heart inflated like it was going to crack right through my ribs. It filled my chest and blocked my throat so that I could not speak. He really did want me the way I wanted himforever. It was only fear for my soul, for the human things he didn't want to take from me, that made him so desperate to leave me mortal. Compared to the fear that he didn't want me, this hurdlemy soulseemed almost insignificant. He took my face tightly between his cool hands and kissed me until I was so dizzy the forest was spinning. Then he leaned his forehead against mine, and I was not the only one breathing harder than usual. â€Å"You were better at it than I was, you know,† he told me. â€Å"Better at what?† â€Å"Surviving. You, at least, made an effort. You got up in the morning, tried to be normal for Charlie, followed the pattern of your life. When I wasn't actively tracking, I was totally useless. I couldn't be around my familyI couldn't be around anyone. I'm embarrassed to admit that I more or less curled up into a ball and let the misery have me.† He grinned, sheepish. â€Å"It was much more pathetic than hearing voices. And, of course, you know I do that, too.† I was deeply relieved that he really seemed to understandcomforted that this all made sense to him. At any rate, he wasn't looking at me like I was crazy. He was looking at me like he loved me. â€Å"I only heard one voice,† I corrected him. He laughed and then pulled me tight against his right side and started to lead me forward. â€Å"I'm just humoring you with this.† He motioned broadly with his hand toward the darkness in front of us as we walked. There was something pale and immense therethe house, I realized. â€Å"It doesn't matter in the slightest what they say.† â€Å"This affects them now, too.† He shrugged indifferently. He led me through the open front door into the dark house and flipped the lights on. The room was just as I'd remembered itthe piano and the white couches and the pale, massive staircase. No dust, no white sheets. Edward called out the names with no more volume than I'd use in regular conversation. â€Å"Carlisle? Esme? Rosalie? Emmett? Jasper? Alice?† They would hear. Carlisle was suddenly standing beside me, as if he'd been there all along. â€Å"Welcome back, Bella.† He smiled. â€Å"What can we do for you this morning? I imagine, due to the hour, that this is not a purely social visit?† I nodded. â€Å"I'd like to talk to everyone at once, if that's okay. About something important.† I couldn't help glancing up at Edward's face as I spoke. His expression was critical, but resigned. When I looked back to Carlisle, he was looking at Edward, too. â€Å"Of course,† Carlisle said. â€Å"Why don't we talk in the other room?† Carlisle led the way through the bright living room, around the corner to the dining room, turning on lights as he went. The walls were white, the ceilings high, like the living room. In the center of the room, under the low-hanging chandelier, was a large, polished oval table surrounded by eight chairs. Carlisle held out a chair for me at the head. I'd never seen the Cullens use the dining room table beforeit was just a prop. They didn't eat in the house. As soon as I turned to sit in the chair, I saw that we were not alone. Esme had followed Edward, and behind her the rest of the family filed in. Carlisle sat down on my right, and Edward on my left. Everyone else took their seats in silence. Alice was grinning at me, already in on the plot. Emmett and Jasper looked curious, and Rosalie smiled at me tentatively. My answering smile was just as timid. That was going to take some getting used to. Carlisle nodded toward me. â€Å"The floor is yours.† I swallowed. Their gazing eyes made me nervous. Edward took my hand under the table. I peeked at him, but he was watching the others, his fate suddenly fierce. â€Å"Well,† I paused. â€Å"I'm hoping Alice has already told you everything that happened in Volterra?† â€Å"Everything,† Alice assured me. I threw her a meaningful look. â€Å"And on the way?† â€Å"That, too,† she nodded. â€Å"Good,† I sighed with relief. â€Å"Then we're all on the same page.† They waited patiently while I tried to order my thoughts. â€Å"So, I have a problem,† I began. â€Å"Alice promised the Volturi that I would become one of you. They're going to send someone to check, and I'm sure that's a bad thingsomething to avoid. â€Å"And so, now, this involves you all. I'm sorry about that.† I looked at each one of their beautiful faces, saving the most beautiful for last. Edward's mouth was turned down into a grimace. â€Å"But, if you don't want me, then I'm not going to force myself on you, whether Alice is willing or not.† Esme opened her mouth to speak, but I held up one finger to stop her. â€Å"Please, let me finish. You all know what I want. And I'm sure you know what Edward thinks, too. I think the only fair way to decide is for everyone to have a vote. If you decide you don't want me, then I guess I'll go back to Italy alone. I can't have them coming here.† My forehead creased as I considered that. There was the faint rumble of a growl in Edward's chest. I ignored him. â€Å"Taking into account, then, that I won't put any of you in danger either way, I want you to vote yes or no on the issue of me becoming a vampire.† I half-smiled on the last word, and gestured toward Carlisle to begin. â€Å"Just a minute,† Edward interrupted. I glared at him through narrowed eyes. He raised his eyebrows at me, squeezing my hand. â€Å"I have something to add before we vote.† I sighed. â€Å"About the danger Bella's referring to,† he continued. â€Å"I don't think we need to be overly anxious.† His expression became more animated. He put his free hand on the shining table and leaned forward. â€Å"You see,† he explained, looking around the table while he spoke, â€Å"there was more than one reason why I didn't want to shake Aro's hand there at the end. There's something they didn't think of, and I didn't want to cine them in.† He grinned. â€Å"Which was?† Alice prodded. I was sure my expression was just as skeptical as hers. â€Å"The Volturi are overconfident, and with good reason. When they decide to find someone, it's not really a problem. Do you remember Demetri?† He glanced down at me. I shuddered. He took that as a yes. â€Å"He finds peoplethat's his talent, why they keep him. â€Å"Now, the whole time we were with any of them, I was picking their brains for anything that might save us, getting as much information as possible. So I saw how Demetri's talent works. He's a trackera tracker a thousand times more gifted than Jarres was. His ability is loosely related to what I do, or what Aro does. He catches the flavor? I don't know how to describe it the tenor of someone's mind, and then he follows that. It works over immense distances. â€Å"But after Aro's little experiments, well† Edward shrugged. â€Å"You think he won't be able to find me,† I said flatly. He was smug. â€Å"I'm sure of it. He relies totally on that other sense. When it doesn't work with you, they'll all be blind.† â€Å"And how does that solve anything?† â€Å"Quite obviously, Alice will be able to tell when they're planning a visit, and I'll hide you. They'll be helpless,† he said with fierce enjoyment. â€Å"It will be like looking for a piece of straw in a haystack!† He and Emmett exchanged a glance and a smirk. This made no sense. â€Å"But they can find you,† I reminded him. â€Å"And I can take care of myself.† Emmett laughed, and reached across the table toward his brother, extending a fist. â€Å"Excellent plan, my brother,† he said with enthusiasm. Edward stretched out his arm to smack Emmett's fist with his own. â€Å"No,† Rosalie hissed. â€Å"Absolutely not,† I agreed. â€Å"Nice.† Jasper's voice was appreciative. â€Å"Idiots,† Alice muttered. Esme just glared at Edward. I straightened up in my chair, focusing. This was my meeting. â€Å"All right, then. Edward has offered an alternative for you to consider,† I said coolly. â€Å"Let's vote.† I looked toward Edward this time; it would be better to get his opinion out of the way. â€Å"Do you want me to join your family?† His eyes were hard and black as flint. â€Å"Not that way. You're staying human.† I nodded once, keeping my face businesslike, and then moved on. â€Å"Alice?† â€Å"Yes.† â€Å"Jasper?† â€Å"Yes,† he said, voice grave. I was a little surprisedI hadn't been at all sure of his votebut I suppressed my reaction and moved on. â€Å"Rosalie?† She hesitated, biting down on her full, perfect bottom lip. â€Å"No.† I kept my face blank and turned my head slightly to move on, but she held up both her hands, palms forward. â€Å"Let me explain,† she pleaded. â€Å"I don't mean that I have any aversion to you as a sister. It's just that this is not the life I would have chosen for myself. I wish there had been someone there to vote no for me.† I nodded slowly, and then turned to Emmett. â€Å"Hell, yes!† He grinned. â€Å"We can find some other way to pick a fight with this Demetri.† I was still grimacing at that when I looked at Esme. â€Å"Yes, of course, Bella. I already think of you as part of my family.† â€Å"Thank you, Esme,† I murmured as I turned toward Carlisle. I was suddenly nervous, wishing I had asked for his vote first. I was sure that this was the vote that mattered most, the vote that counted more than any majority. Carlisle wasn't looking at me. â€Å"Edward,† he said. â€Å"No,† Edward growled. His jaw was strained tight, his lips curled back from his teeth. â€Å"It's the only way that makes sense,† Carlisle insisted. â€Å"You've chosen not to live without her, and that doesn't leave me a choice.† Edward dropped my hand, shoving away from the table. He stalked out of the room, snarling under his breath. â€Å"I guess you know my vote.† Carlisle sighed. I was still staring after Edward. â€Å"Thanks,† I mumbled. An earsplitting crash echoed from the other room. I flinched, and spoke quickly. â€Å"That's all I needed. Thank you. For wanting to keep me. I feel exactly the same way about all of you, too.† My voice was jagged with emotion by the end. Esme was at my side in a flash, her cold arms around me. â€Å"Dearest Bella,† she breathed. I hugged her back. Out of the corner of my eye, I noticed Rosalie looking down at the table, and I realized that my words could be construed in two ways. â€Å"Well, Alice,† I said when Esme released me. â€Å"Where do you want to do this?† Alice stared at me, her eyes widening with terror. â€Å"No! No! NO!† Edward roared, charging back into the room. He was in my face before I had time to blink, bending over me, his expression twisted in rage. â€Å"Are you insane?† he shouted. â€Å"Have you utterly lost your mind?† I cringed away, my hands over my ears. â€Å"Um, Bella,† Alice interjected in an anxious voice. â€Å"I don't think I'm ready for that. I'll need to prepare† â€Å"You promised,† I reminded her, glaring under Edward's arm. â€Å"I know, but Seriously, Bella! I don't have any idea how to not killyou.† â€Å"You can do it,† I encouraged. â€Å"I trust you.† Edward snarled in fury. Alice shook her head quickly, looking panicked. â€Å"Carlisle?† I turned to look at him. Edward grabbed my face in his hand, forcing me to look at him. His other hand was out, palm toward Carlisle. Carlisle ignored that. â€Å"I'm able to do it,† he answered my question. I wished I could see his expression. â€Å"You would be in no danger of me losing control.† â€Å"Sounds good.† I hoped he could understand; it was hard to talk clearly the way Edward held my jaw. â€Å"Hold on,† Edward said between his teeth. â€Å"It doesn't have to be now.† â€Å"There's no reason for it not to be now,† I said, the words coming out distorted. â€Å"I can think of a few.† â€Å"Of course you can,† I said sourly. â€Å"Now let go of me.† He freed my face, and folded his arms across his chest. â€Å"In about two hours, Charlie will be here looking for you. I wouldn't put it past him to involve the police.† â€Å"All three of them.† But I frowned. This was always the hardest part. Charlie, Renee. Now Jacob, too. The people I would lose, the people I would hurt. I wished there was some way that I could be the only one to suffer, but I knew that was impossible. At the same time, I was hurting them more by staying human. Putting Charlie in constant danger through my proximity. Putting Jake in worse danger still by drawing his enemies across the land he felt bound to protect. And ReneeI couldn't even risk a visit to see my own mother for fear of bringing my deadly problems along with me! I was a danger magnet; I'd accepted that about myself. Accepting this, I knew I needed to be able to take care of myself and protect the ones I loved, even if that meant that I couldn't be with them. I needed to be strong. â€Å"In the interest of remaining inconspicuous,† Edward said, still talking through his gritted teeth, but looking at Carlisle now, â€Å"I suggest that we put this conversation off, at the very least until Bella finishes high school, and moves out of Charlie's house.† â€Å"That's a reasonable request, Bella,† Carlisle pointed out. I thought about Charlie's reaction when he woke up this morning, ifafter all that life had put him through in the last week with Harry's loss, and then I had put him through with my unexplained disappearancehe were to find my bed empty. Charlie deserved better than that. It was just a little more time; graduation wasn't so far away I pursed my lips. â€Å"I'll consider it.† Edward relaxed. His jaw unclenched. â€Å"I should probably take you home,† he said, more calm now, but clearly in a hurry to get me out of here. â€Å"Just in case Charlie wakes up early.† I looked at Carlisle. â€Å"After graduation?† â€Å"You have my word.† I took a deep breath, smiled, and turned back to Edward. â€Å"Okay. You can take me home.† Edward rushed me out of the house before Carlisle could promise me anything else. He took me out the back, so I didn't get to see what was broken in the living room. It was a quiet trip home. I was feeling triumphant, and a little smug. Scared stiff, too, of course, but I tried not to think about that part. It did me no good to worry about the painthe physical or the emotionalso I wouldn't. Not until I absolutely had to. When we got to my house, Edward didn't pause. He dashed up the wall and through my window in half a second. Then he pulled my arms frcm around his neck and set me on the bed. I thought I had a pretty good idea of what he was thinking, but his expression surprised me. Instead of furious, it was calculating. He paced silently back and forth across my dark room while I watched with growing suspicion. â€Å"Whatever you're planning, it's not going to work,† I told him. â€Å"Shh. I'm thinking.† â€Å"Ugh,† I groaned, throwing myself back on the bed and pulling the quilt over my head. There was no sound, but suddenly he was there. He flipped the cover back so he could see me. He was lying next to me. His hand reached up to brush my hair from my cheek. â€Å"If you don't mind, I'd much rather you didn't hide your face. I've lived without it for as long as I can stand. Now tell me something.† â€Å"What?† I asked, unwilling. â€Å"If you could have anything in the world, anything at all, what would it be?† I could feel the skepticism in my eyes. â€Å"You.† He shook his head impatiently. â€Å"Something you don't already have.† I wasn't sure where he was trying to lead me, so I thought carefully before I answered. I came up with something that was both true, and also probably impossible. â€Å"I would want Carlisle not to have to do it. I would want you to change me.† I watched his reaction warily, expecting more of the fury I'd seen at his house. I was surprised that his expression didn't change. It was still calculating, thoughtful. â€Å"What would you be willing to trade for that?† I couldn't believe my ears. I gawked at his composed face and blurted out the answer before I could think about it. â€Å"Anything.† He smiled faintly, and then pursed his lips. â€Å"Five years?† My face twisted into an expression somewhere between chagrin and horror. â€Å"You said anything,† he reminded me. â€Å"Yes, but you'll use the time to find a way out of it. I have to strike while the iron is hot. Besides, it's just too dangerous to be humanfor me, at least. So, anything but that.† He frowned. â€Å"Three years?† â€Å"No!† â€Å"Isn't it worth anyrhing to you at all? â€Å" I thought about how much I wanted this. Better to keep a poker face, I decided, and not let him know how very much that was. It would give me more leverage. â€Å"Six months?† He rolled his eyes. â€Å"Not good enough.† â€Å"One year, then,† I said. â€Å"That's my limit.† â€Å"At least give me two.† â€Å"No way. Nineteen I'll do. But I'm not going anywhere near twenty. If you're staying in your teens forever, then so am I.† He thought for a minute. â€Å"All right. Forget time limits. If you want me to be the onethen you'll just have to meet one condition.† â€Å"Condition?† My voice went flat. â€Å"What condition?† His eyes were cautioushe spoke slowly. â€Å"Marry me first.† I stared at him, waiting â€Å"Okay. What's the punch line?† He sighed. â€Å"You're wounding my ego, Bella. I just proposed to you, and you think it's a joke.† â€Å"Edward, please be serious.† â€Å"I am one hundred percent serious.† He gazed at me with no hint of humor in his face. â€Å"Oh, c'mon,† I said, an edge of hysteria in my voice. â€Å"I'm only eighteen.† â€Å"Well, I'm nearly a hundred and ten. It's time I settled down.† I looked away, out the dark window, trying to control the panic before it gave me away. â€Å"Look, marriage isn't exactly that high on my list of priorities, you know? It was sort of the kiss of death for Renee and Charlie.† â€Å"Interesting choice of words.† â€Å"You know what I mean.† He inhaled deeply. â€Å"Please don't tell me that you're afraid of the commitment,† his voice was disbelieving, and I understood what he meant. â€Å"That's not it exactly,† I hedged. â€Å"I'm afraid of Renee. She has some really intense opinions on getting married before you're thirty.† â€Å"Because she'd rather you became one of the eternal damned than get married.† He laughed darkly. â€Å"You think you're joking.† â€Å"Bella, if you compare the level of commitment between a marital union as opposed to bartering your soul in exchange for an eternity as a vampire† He shook his head. â€Å"If you're not brave enough to marry me, then† â€Å"Well,† I interrupted. â€Å"What if I did? What if I told you to take me to Vegas now? Would I be a vampire in three days?† He smiled, his teeth flashing in the dark. â€Å"Sure,† he said, calling my bluff. â€Å"I'll get my car.† â€Å"Dammit.† I muttered. â€Å"I'll give you eighteen months.† â€Å"No deal,† he said, grinning. â€Å"I like this condition.† â€Å"Fine. I'll have Carlisle do it when I graduate.† â€Å"If that's what you really want.† He shrugged, and his smile became absolutely angelic. â€Å"You're impossible,† I groaned. â€Å"A monster.† He chuckled. â€Å"Is that why you won't marry me?† I groaned again. He leaned toward me; his night-dark eyes melted and smoldered and shattered my concentration. † Please, Bella?† he breathed. I forgot how to breathe for a moment. When I recovered, I shook my head quickly, trying to clear my suddenly clouded mind. â€Å"Would this have gone better if I d had time to get a ring.'† â€Å"No! No rings!† I very nearly snouted. â€Å"Now you've done it,† he whispered. â€Å"Oops.† â€Å"Charlie's getting up; I'd better leave,† Edward said with resignation. My heart stopped beating. He gauged my expression for a second. â€Å"Would it be childish of me to hide in your closet, then?† â€Å"No,† I whispered eagerly. â€Å"Stay. Please.† Edward smiled and disappeared. I seethed in the darkness as I waited for Charlie to check on me. Edward knew exactly what he was doing, and I was willing to bet that all the injured surprise was part of the ploy. Of course, I still had the Carlisle option, but now that I knew there was a chance that Edward would change me himself, I wanted it bad. He was such a cheater. My door cracked open. â€Å"Morning, Dad.† â€Å"Oh, hey, Bella.† He sounded embarrassed at getting caught. â€Å"I didn't know you were awake.† â€Å"Yeah. I've just been waiting ior you to wake up so I could take a shower.† I started to get up. â€Å"Hold on,† Charlie said, flipping the light on. I blinked in the sudden brightness, and carefully kept my eyes away from the closet. â€Å"Let's talk for a minute first.† I couldn't control my grimace. I'd forgotten to ask Alice for a good excuse. â€Å"You know you're in trouble.† â€Å"Yeah, I know.† â€Å"I just about went crazy these last three days. I come home from Harry's funeral, and you're gone. Jacob could only tell me that you'd run off with Alice Cullen, and that he thought you were in trouble. You didn't leave me a number, and you didn't call. I didn't know where you were or whenor ifyou were coming back. Do you have any idea how how† He couldn't finish the sentence. He sucked in a sharp breath and moved on. â€Å"Can you give me one reason why I shouldn't ship you off to Jacksonville this second?† My eyes narrowed. So it was going to be threats, was it? Two could play at that game. I sat up, pulling the quilt around me. â€Å"Because I won't go.† â€Å"Now just one minute, young lady† â€Å"Look, Dad, I accept complete responsibility for my actions, and you have the right to ground me for as long as you want. I will also do all the chores and laundry and dishes until you think I've learned my lesson. And I guess you're within your rights if you want to kick me out, toobut that won't make me to go to Florida.† His face turned bright red. He took a few deep breaths before he answered. â€Å"Would you like to explain where you've been?† Oh, crap. â€Å"There was an emergency.† He raised his eyebrows in expectation of my brilliant explanation. I filled my cheeks with air and then blew it out noisily. â€Å"I don't know what to tell you, Dad. It was mostly a misunderstanding. He said, she said. It got out of hand.† He waited with a distrustful expression. â€Å"See, Alice told Rosalie about me jumping off the cliff† I was scrambling frantically to make this work, to keep it as close to the truth as possible so that my inability to lie convincingly would not undermine the excuse, but before I could go on, Charlie's expression reminded me that he didn't know arything about thecliff. Major oops. As if I wasn't already toast. â€Å"I guess I didn't tell you about that,† I choked out. â€Å"It was nothing. Just messing around, swimming with Jake. Anyway, Rosalie told Edward, and he was upset. She sort of accidentally made it sound like I wa? trying to kill myself or something. He wouldn't answer his phone, so Alice dragged me to L.A., to explain in person.† I shrugged, desperately hoping that he would not be so distracted by my slip that he'd miss the brilliant explanation I'd provided. Charlie's face was frozen. â€Å"Were you trying to kill yourself, Bella?† â€Å"No, of course not. Just having fun with Jake. Cliff diving. The La Push kids do it all the time. Like I said, nothing.† Charlie's face heated upfrom frozen to hot with fury. â€Å"What's it to Edward Cullen anyway?† he barked. â€Å"All this time, he's just left you dangling without a word† I interrupted him. â€Å"Another misunderstanding.† His face flushed again. â€Å"So is he back then?† â€Å"I'm not sure what the exact plan is. I think they all are.† He shook his head, the vein in his forehead pulsing. â€Å"I want you to stay away from him, Bella. I don't trust him. He's rotten for you. I won't let him mess you up like that again.† â€Å"Fine,† I said curtly. Charlie rocked back onto his heels. â€Å"Oh.† He scrambled for a second, exhaling loudly in surprise. â€Å"I thought you were going to be difficult.† â€Å"I am.† I stared straight into his eyes. â€Å"I meant, ‘Fine, I'll move out.'† His eyes bulged; his face turned puce. My resolve wavered as I started to worry about his health. He was no younger than Harry â€Å"Dad, I don't want to move out,† I said in a softer tone. â€Å"I love you. I know you're worried, but you need to trust me on this. And you're going to have to ease up on Edward if you want me to stay. Do you want me to live here or not?† â€Å"That's not fair, Bella. You know I want you to stay.† â€Å"Then be nice to Edward, because he's going to be where I am.† I said it with confidence. The conviction of my epiphany was still strong. â€Å"Not under my roof,† Charlie stormed. I sighed a heavy sigh. â€Å"Look, I'm not going to give you any more ultimatums tonightor I guess it's this morning. Just think about it for a few days, okay? But keep in mind that Edward and I are sort of a package deal.† â€Å"Bella† â€Å"Think it over,† I insisted. â€Å"And while you're doing that, could you give me some privacy? I really need a shower.† Charlie's face was a strange shade of purple, but he left, slamming the door behind him. I heard him stomp furiously down the stairs. I threw off my quilt, and Edward was already there, sitting in the rocking chair as if he d been present through the whole conversation. â€Å"Sorry about that,† I whispered. â€Å"It's not as if I don't deserve far worse,† he murmured. â€Å"Don't start anything with Charlie over me, please. â€Å" â€Å"Don't worry about it,† I breathed as I gathered up my bathroom things and a set of clean clothes. â€Å"I will start exactly as much as is necessary, and no more than that. Or are you trying to tell me I have nowhere to go?† I widened my eyes with false alarm. â€Å"You'd move in with a house full of vampires?† â€Å"That's probably the safest place for someone like me. Besides† I grinned. â€Å"If Charlie kicks me out, then there's no need for a graduation deadline, is there?† His jaw tightened. â€Å"So eager for eternal damnation,† he muttered. â€Å"You know you don't really believe that.† â€Å"Oh, don't I?† he fumed. â€Å"No. You don't.† He glowered at me and started to speak, but I cut him off. â€Å"If you really believed that you'd lost your soul, then when I found you in Volterra, you would have realized immediately what was happening, instead of thinking we were both dead together. But you didn'tyou said ‘Amazing. Carlisle was right,'† I reminded him, triumphant. â€Å"There's hope in you, after all.† For once, Edward was speechless. â€Å"So let's both just be hopeful, all right?† I suggested. â€Å"Not that it matters. If you stay, I don't need heaven.† He got up slowly, and came to put his hands on either side of my face as he stared into my eyes. â€Å"Forever,† he vowed, still a little staggered. â€Å"That's all I'm asking for,† I said, and stretched up on my toes so that I could press my lips to his.

Ballistics (Forensic Science)

Ballistics is one of the essential components of forensic science. Researchers and scholars in ballistics actively work to improve the quality of ballistics research methods and to enhance the effectiveness of all forensic procedures. It should be noted, that ballistics was not always widely recognized as a scientific method of firearms identification. For many years, courts and law enforcement professionals viewed ballistics as unnecessary and unimportant in the investigation of the major criminal cases.Now, with the advent of the new technological age, ballistics has not only turned into the critical element of success in forensics, but is actively aligned with advanced technologies to speed up the process of identification of firearms. Ballistics (Forensic Science) Introduction Ballistics is one of the essential components of forensic science. Researchers and scholars in ballistics actively work to improve the quality of ballistics research methods and to enhance the effectiveness of all forensic procedures.It should be noted, that ballistics was not always widely recognized as a scientific method of firearms identification. For many years, courts and law enforcement professionals viewed ballistics as unnecessary and unimportant in the investigation of the major criminal cases. Now, with the advent of the new technological age, ballistics has not only turned into the critical element of success in forensics, but is actively aligned with advanced technologies to speed up the process of identification of firearms.Ballistics: definition and history To begin with, â€Å"ballistics, in the most general sense, is the study of firearms – ‘guns’ in the vernacular. As a term of art, ballistics technically refers to the study of a bullet’s path from the firearm, through the air, and into a target† (Carlucci & Jacobson, 2007). From the viewpoint of forensics, ballistics comes up to represent a system of principles and calculations used to match recovered bullets (or their casings) to the firearms which were used to fire them.To a large extent, the study of ballistics is based on the whole set of physical laws, starting with the law of ideal gas and up to the principles of explosion and pressure within the firearms. Currently, ballistics is used to resolve the major firearms complexities, which law enforcement professionals face in the process of investigating a crime. A professional in practical ballistics works to restore the picture of the crime using firearms, bullets, casings, or their residues, and to match them to the marks that had been left on the crime scene.Despite the seriousness of the firearms identification process and the role which ballistics may play for the effectiveness of other forensic procedures, it was not before the beginning of the 1950s that the term â€Å"ballistics† became a widely recognized description of firearms studies (Warlow, 2004). The history of ballistics dates back to the times, when firearms were made manually and individually and each bullet was unique. Gunsmiths were the ones to produce flintlocks and matchlocks, and each firearm bore the sign of its creator.Early firearms could be readily compared to the works of art, for even â€Å"the screws that held together early firearms were handmade and often specific in width and pitch of the threads† (Carlucci & Jacobson, 2007). In conditions where firearms could be distinguished from one another without a difficulty and where every gun bore a unique sign of its creator, matching bullets to firearms was not a difficult task. As a result, early forensic scientists did not really need the knowledge of ballistics in its current form.Matching bullets to their molds was an easy-to-accomplish procedure and did not require any specialized skills or calculations. At the beginning of the 19th century, however, bullets and firearms have turned into the products of mass production, and the form of the bullet was standardized (Carlucci & Jacobson, 2007). Although the amount of firearms models was rather limited and a criminal investigator could easily name the firearm from which specific bullets came, it was no longer possible to distinguish between different variations of firearms that had been produced by one manufacturer (Carlucci & Jacobson, 2007).That is why forensic professionals have become increasingly interested in studying specific features of bullets and firearms that might have been concealed from the naked eye. Phillip Gavelle was one of the first to use microscopes to investigate the features of bullets and compare them to the details and characteristics of the crime scene (Warlow, 2004). With time, experts have also come to realize the role which firing pin and breech marks could play for the identification of firearms (Carlucci & Jacobson, 2007).Unfortunately, the term â€Å"ballistics† and the importance of firearms investigation did not attract public atte ntion, and only after the Sacco and Vanzetti case, as well as the publication of the three firearms identification treatises, the court has officially recognized ballistics as a forensic science, giving law enforcement professionals a chance to improve the quality of all forensic procedures and to develop a new system of forensic methodology with regard to firearms (Warlow, 2004).Ballistics in its modern form: internal, external, and terminal Certainly, with the scientific contribution which Goddard made to the development of ballistics, we would hardly be aware of how effective firearms identification could be for resolving the most complicated criminal cases. Now, as guns and firearms are mass-produced, and thousands and millions of individuals are given the legal right to carry concealed arms, ballistics gradually turns into the central component in the system of law enforcement principles used to reduce and prevent crime threats.In its current form, ballistics is usually divided into the three distinct areas: internal, external, and terminal ballistics. This division is necessary to make the study of separate ballistics aspects more effective, and to provide forensic scientists with sufficient analytical instruments. Moreover, this division is based on the path, which a bullet usually passes down the barrel, through the air, and finally, through a target. Internal ballistics (or initial ballistics) is concentrated around the path, which a bullet passes within the gun (Carlucci & Jacobson, 2007).Although measuring and describing the path of the bullet within the gun is very difficult and almost impossible, forensic scientists use velocity (or muzzle velocity) as the central forensic criterion in the study of internal bullet behaviors. Internal ballistics â€Å"concerns what happens within a time span of in the region of 2 ms between the impact of the firing pin or striker and the exit of the bullet or shot charge from the muzzle end of the barrel† (W arlow, 2004).Energy transfer, pressures and powders, combustion residues, as well as recoil in the weapon are the elements forensic professionals need to know, in order to relate the processes within the gun to the results they have produced on the crime scene. As soon as the bullet leaves the barrel, it becomes an object of external ballistics study. The latter is concerned with the pathway the bullet passes after leaving the barrel and involves the study of missile trajectory, and the impact which air gravity and resistance might have caused on it (Carlucci & Jacobson, 2007).In terms of smooth-bored guns, forensic scientists are usually concerned about the changes that might have occurred in the spread of the shot charge (Warlow, 2004). Crosswinds and the way they change missile trajectory are just another subjects of forensic research in external ballistics. External ballistics usually seeks to determine the scope of influences other materials could produce on the bullet. For exa mple, and Warlow (2004) emphasizes this fact, unburned propellant particles will tend to significantly affect the bullet at close range.Bullet stability, flight, sectional density and shape, and even aerodynamic stabilization form the numerical basis of external ballistics and turn it into a distinctively mathematical field, well-known for its complex algebraic and geometric calculations. The study of the bullet path would be incomplete without researching the processes and changes the bullet undergoes after hitting a target. Upon striking a target, the bullet either deforms or disintegrates, simultaneously damaging or destroying the target (Carlucci & Jacobson, 2007).These elements are the objects of terminal ballistics research. Terminal ballistics professionals work to link the character of the target destruction to the missile trajectory, its velocity, specific characteristics, design, and the features of the target itself. Given that the majority of targets which terminal balli stics investigates are humans, and taking into account the complex structure of the human body, terminal ballistics is probably the most complicated and the most responsible area of forensic firearms science.Researchers suggest that the bullet’s behaviors after hitting the human target are too unexpected and too unpredictable (Carlucci & Jacobson, 2007; Warlow, 2004). Forensic scientists are not always able to establish the link between the pathway the bullet has passed and the injuries found in a victim’s body. That is why terminal ballistics is a complex study of ricochet, impact, penetration, and kinetic forces that are considered responsible for the major motional shifts the bullet undergoes after hitting a target.Forensic ballistics: the new technological stage With the number of physical laws ballistics uses to match the bullets to firearms and to investigate the pathway the bullet passes from the barrel through a target, it is natural that ballistics professiona ls are involved into complex computation processes. However, with the advent of the new technological age forensic scientists have been offered an opportunity to use computer and software technologies for calculation purposes.Now, ballistics software models are extremely sophisticated in contents, but extremely easy in use. IT professionals were able to simplify and integrate the complicated systems of motion, dynamics, gravity and location, as well as hundreds of other physical concepts and principles into a universal system of calculation, which specialists in ballistics use to compute and describe the missile trajectory and bullet flight performance.Unfortunately, there is a whole set of problems to resolve before ballistics software turns into a reliable tool of forensic knowledge. For example, external ballistics technology is concerned with the way equations of motion can be simplified to improve the quality of six-degrees-of-freedom equations and to speed up the process of th eir solution (Belzer, Holzman & Kent, 2006). â€Å"There are also problems with fluid mechanics. These may include matters of universal interest, such as similarity principles, e. g. for transonic flow† (Belzer, Holzman & Kent, 2006).In terminal ballistics, chemistry is the major obstacle IT designers and developers face on their way to creating an effective system of ballistics computation; fluid mechanics also makes it difficult to design complex equations that would take into account the principles of heat conduction, viscosity, chemical reactions, and temperature dependencies (Belzer, Holzman & Kent, 2006).Nevertheless, it is with the emergence of new technologies that ballistics has been given a second breathe and it is in the current technological age that ballistics is likely to become a rapidly evolving area of forensic science and law enforcement, with the emphasis made on the speed and quality of ballistics solutions. Conclusion For many years, ballistics remained a n area of knowledge mostly neglected by forensic professionals.However, as firearms have been gradually turning into the objects of mass production, it was becoming more and more difficult to match bullets to the firearms from which they came. As a result, ballistics has come to represent a complex system of investigation principles aimed at researching the bullet behavior on its way from the barrel and through a target, as well as matching bullets to specific firearms and the marks they have left on the crime scene.Now, under the impact of technological progress, ballistics has been successfully aligned with the complex computation models, and although there is still much to resolve before ballistics becomes a purely technological field, it is obvious that ballistics will remain one of the most rapidly evolving areas of forensic science, with the emphasis made on the speed and quality of ballistics solutions.References Belzer, J. , Holzman, A.

Study on Rana Pipiens essays

Study on Rana Pipiens essays Distribution: Found throughout Ontario but more abundant in southern and central Americas. Range: Adults maintain small home ranges (up to 500 m2) in fields or open forest during the summer. Where terrestrial habitats are quite dry, home ranges include some shoreline. A minimum of 4 ha of terrestrial habitat is recommended for the vicinity of breeding sites, however, individual adults may move several kilometres away. Most recently metamorphosed froglets stay within 20 m of shoreline although some froglets begin dispersal before metamorphosis is entirely complete. Diet: Larvae eat algae, phytoplankton, periphyton and detritus. Adults eat mainly invertebrates but will also take tadpoles or very small froglets. Reproduction: Successful breeding sites are permanent ponds, marshes, or pools or backwaters of streams. Eggs and tadpoles require warm (prefer 18o - 28o C), shallow, sunny areas. Breeding occurs from mid-March to mid-May in southern Ontario, and a few weeks later further north. Metamorphosis occurs in 2-3 months. Tadpoles require minimum oxygen concentrations of 3 ppm. Habitat: Relative to bullfrogs and green frogs, leopard frogs use open fields more and prefer denser terrestrial vegetation. In aquatic habitats, submerged vegetation, detritus and soft mud are used for cover. Froglets require muddy shorelines, lily pads, rocks, logs or beaver dams with clear access to deeper water. Adults prefer unmowed fields (15 - 30 cm high, no more than 1 m high vegetation) or open forest in the vicinity of Corridors may be required among breeding, hibernation and summeringhabitats, within 2 km. These may be either aquatic (streams or rivers) or terrestrial (field or forest, usually not cropland except during periods of irrigation). Hibernate in deep or running water that will not freeze solid ...

The Disaster Cycle

The Disaster Cycle The disaster cycle or the disaster life cycle consists of the steps that emergency managers take in planning for and responding to disasters. Each step in the disaster cycle correlates to part of the ongoing cycle that is emergency management. This disaster cycle is used throughout the emergency management community, from the local to the national and international levels and it is: Mitigation: Minimizing the effectsPreparedness: Planning the responseResponse: Efforts to minimize hazards that were created by the disasterRecovery: Returning the community back to normal with relief Starting the Disaster Cycle Again Finally, using the lessons learned from the response, recovery, and mitigation phases of the disaster the emergency manager and government officials return to the preparedness phase and revise their plans and their understanding of the material and human resources needs for a particular disaster in their community.

Time Management - Research Paper Example From the results obtained in this study, it is clear that time management is key in ensuring that students realize better performance. As highlighted above, students with a higher self time management skills had a higher mean score on the TASK score. The statistical analysis proved that time management is correlated with student performance. This is because, students who were better placed in terms of time management skills professionally, ranked higher in terms of performance. The SPSS analysis indicates there is moderate to strong positive correlation between time management and student achievement. It was observed the five participants that completed the survey had their TAKS scores above the seventy percent-tile. It is undisputed that the process of teaching takes a considerable amount of time, and in school, just like it applies to other areas, there is never enough of it. As widely cited the biggest challenges for teachers, as well as students entail managing time. It has been noted that time management is a thread running through all aspects of teaching. It determines various activities such as organizing the day, deciding how often and how long various subjects are to be taught, organizing classroom, recording the progress of students, and how to reduce keep time-consuming behavioral problems. In the view of Berry, Daughtrey and Wieder effective use of time in school starts with efficient classroom management and organization. According to Ames and Archer most of the essentials of the classroom life often involve management of time. ... Endeavoring to elucidate on this issue, this paper seeks to investigate if there exists a significant correlation between teachers with time management skills and student achievement. This would be based on Texas Assessment of Knowledge and Skills (TAKS) scores. Statement of the Problem There is a growing pressure on teachers, students and policy makers within education sector to measure up to the expected standards of performance. Students are expected to work hard and make sure they make their parents and teachers proud by passing their exams. As often the case, administrators in charge of schools are under pressure to comply with government policies, which support better utilization of time for the better of student success. For this to be achieved there is need for school administrators, the student fraternity and the entire teaching staff to impress programs that are geared towards maximizing on time utility. This can only be done if the issue of time management is taken into co nsideration. This points to the fact that such schools need to take into consideration the role of time management and its impact on instructional time in case they so wish to meet the demands of increasing student achievement. Research Questions This study was driven by the research questions below: 1. Can the student success be influenced by time management skills? 2. Does teacher’s with time management skills and student achievement correlate? Purpose of the Study The study aimed at establishing the link between student’s achievement and time management skills. This shall be achieved through examining the two important parameters: time management skills and the academic success of students’ basing on the student scores on Texas Assessment of Knowledge and Skills
