Pill Bug Lab Essay

Introduction The study of animal behavior is ethology. There are two basic categories of animal behavior: learned behavior and innate, or inherited, behavior. Learned behavior is when animals acquire knowledge about their behavior through experience. Unlike learned behaviors, innate behavior exists naturally in animals, meaning that animals are born with some behaviors. In order to find a suitable environment, animals use orientation behaviors. The two types of orientation behaviors are taxis and kinesis. Taxis is an animal’s natural ability to know whether a stimulus is suitable or unsuitable. Kinesis is defined as random movement that is not exhibited in response to a stimulus (Lab #12). Isopods, otherwise known as pill bugs, are scavengers that feed on dead and decaying plants and animals. Pill bugs vary in color from dark grey to dark brown and are easily recognized by their oval, segmented bodies. They are the only crustaceans that have adapted to living their entire life on land (Potter). However, pill bugs still breathe through gills; therefore, they are restricted to live in environments with high humidity (â€Å"Isopod, Pillbug, Sow Bug Information†). Isopods tend to remain under objects during the day and are most active at night. They thrive in moist shaded places: under rocks, large fallen trees, and flower pots and in moist leaf litter and damp basements. Experimental Hypothesis If pill bugs are generally found in dark environments such as under flower pots, under logs, under welcome mats, and in piles of leaves, then they will prefer the dark side of the choice chamber rather than the light side of the chamber. Experimental Design Materials -2 sheets of filter paper -choice chamber -2 lids -paintbrush -10 pill bugs -box -timer Procedures Collect filter paper, a choice chamber, 2 lids, a paintbrush, 10 pill bugs, a box, and a stopwatch. Set the materials up. First, place the choice chamber on the table. Next, position the filter in the bottom of the chamber. Then, place 5 pill bugs on each side of the chamber. Lastly, place the lids on top of each side. In order to create a dark atmosphere, place the box over one side of the choice chamber. This lab will be completed over the course of ten minutes. The main task is to observe the position of the pill bugs in two minute intervals using the stopwatch. Use the paintbrush to lead any stray pill bugs back into the choice chamber. Write down any observations and/or comments.

How Ethernet Works essays

How Ethernet Works essays What Is Ethernet and How Is It Used? A gentlemen by the name of Bob Metcalfe realized that he could improve on a system called the Aloha System which arbitrated access to a shared communications channel. He developed a new system that included a mechanism that detects when a collision occurs (collision detect). The system also includes "listen before talk," in which stations listen for activity (carrier sense) before transmitting, and supports access to a shared channel by multiple stations (multiple access). Put all these components together, and you can see why the Ethernet channel access protocol is called Carrier Sense Multiple Access with Collision Detect (CSMA/CD). Metcalfe also developed a much more sophisticated backoff algorithm, which, in combination with the CSMA/CD protocol, allows the Ethernet system to function all the way up to 100 percent load. In late 1972, Metcalfe and his Xerox PARC colleagues developed the first experimental Ethernet system to interconnect the Xerox Alto. The Alto was a personal workstation with a graphical user interface, and experimental Ethernet was used to link Altos to one another, and to servers and laser printers. The signal clock for the experimental Ethernet interfaces was derived from the Alto's system clock, which resulted in a data transmission rate on the experimental Ethernet of 2.94 Mbps. Metcalfe's first experimental net was called the "Alto Aloha Network." In 1973 Metcalfe changed the name to "Ethernet," to make it clear that the system could support any computer, and not just Altos, and to point out that his new network mechanisms had evolved well beyond the Aloha system. He chose to base the name on the word "ether" as a way of describing an essential feature of the system: the physical medium (cable) carries bits to all stations, much the same way that the old "luminiferous ether" was once thought to propagate electromagnetic waves through space. Physicists Michelson an...

Definition and Examples of Zeugma

Definition and Examples of Zeugma Zeugma is a  rhetorical term for the use of a word to modify or govern two or more words although its use may be grammatically or logically correct with only one. Adjective: zeugmatic. Rhetorician Edward P.J. Corbett offers this distinction between zeugma and syllepsis: in zeugma, unlike syllepsis, the single word does not fit grammatically or idiomatically with one member of the pair. Thus, in Corbetts view, the first example below would be syllepsis, the second zeugma: You are free to execute your laws, and your citizens, as you see fit.(Star Trek: The Next Generation)Kill the boys and the luggage!​(Fluellen in William Shakespeares Henry V) However, as Bernard Dupriez points out in A Dictionary of Literary Devices (1991), There is little agreement among rhetoricians on the difference between syllepsis and zeugma, and Brian Vickers notes that even the Oxford English Dictionary confuses syllepsis and zeugma (Classical Rhetoric in English Poetry, 1989). In contemporary rhetoric, the two terms are commonly used interchangeably to refer to a figure of speech in which the same word is applied to two others in different senses. Etymology From the Greek, a yoking, a bond Examples and Observations Zeugma is when a word applies to two others in different ways; or to two words when it only semantically suits one. An example of the former quotes Alanis Morissette: You held your breath and the door for me. How chivalrous and zeugmatic. An example of the latter is with wailing mouths and hearts- but dont blame Morissette for this doggerel.(Gary Nunn, Move Over, George Orwell- This Is How to Sound Really Clever. The Guardian, October 11, 2013)He carried a strobe light and the responsibility for the lives of his men.(Tim OBrien, The Things They Carried. McClelland Stewart, 1990)She arrived in a taxi and a flaming rage.(John Lyons, Semantics. Cambridge University  Press, 1977)We were partners, not soul mates, two separate people who happened to be sharing a menu and a life.(Amy Tan, The Hundred Secret Senses. Ivy Books, 1995)[H]e was alternately cudgelling his brains and his donkey when, passing the workhouse, his eyes encountered the bill on the gate.(Charles Dickens, Oliver Twist , 1839) I just blew my nose, a fuse, and three circuit breakers.(The Jim Henson Hour, 1989)I was in no sort of nick for this encounter, I admit, full of fear and afternoon scotch and the homeward tug.(Marin Amis, Money. Jonathan Cape, 1984)Whether the nymph shall break Dianas law,Or some frail China-jar receive a flaw,Or stain her honour, or her new brocade.(Alexander Pope, The Rape of the Lock, 1717)She lowered her standards by raising her glass,Her courage, her eyes and his hopes.(Flanders and Swann, Have Some Madeira, MDear)The theme of the Egg Hunt is learning is delightful and delicious- as, by the way, am I.(Allison Janney as C.J. Cregg in The West Wing) Zeugma as a Writing Fault Like syllepsis, the figure known as zeugma uses a single word to link two thoughts, but in syllepsis the relationship of the linking word to both ideas is correct, whereas in zeugma the relationship is correct for one idea but not for the other. A fabricated example of zeugma might be, He sat munching his sandwich and his beer. An actual example from fiction is, Something odd in the behavior of the pair held his attention and his curiosity. The term zeugma is often used to refer to syllepsis, but as here distinguished it obviously is a writing fault, which syllepsis is not. (Theodore Bernstein, The Careful Writer: A Modern Guide to English Usage. Simon Schuster, 1965)Zeugma is often accidental, as in She wore a rusty black dress, a feather boa, and an alligator handbag; since wore has no legitimate application to handbag, this zeugma is an error. (Edward D. Johnson, The Handbook of Good English. Washington Square, 1991)Confusing and Contradictory Distinctions Between Zeugma and Syll epsisAlthough commentators have historically tried to distinguish between zeugma and syllepsis, the distinctions have been confusing and contradictory: even today agreement on definitions in the rhetorical handbooks is virtually nil (The New Princeton Encyclopedia of Poetry and Poetics, 1993).  Were better off using zeugma in its broadest sense and not confusing matters by introducing syllepsis, a little-known term the meaning of which even the experts cant agree on.  (Bryan A. Garner, The Oxford Dictionary of American Usage and Style, 4th ed. Oxford University Press, 2016) Pronunciation: ZOOG-muh

Essential factors for personal development and success in the United Essay

Essential factors for personal development and success in the United States of America - Essay Example This essay will describe the factors that attribute to success within the American setting as reflected by Yang in his article. According to Yang, Asian Americans are having a difficult time within the American setting. Asian Americans grow up with Asian intrinsic values that prove very different from what the American culture upholds. Children born of Asian families in America have a unique set of values that defines the personality that they adopt. It is evident that culture plays a critical part in personality development, explaining why Yang describes how the Asian culture has molded them into individuals that exhibit significant differences from the Americans within the class setting, workplace and in relationships (Barrios, 2013). . However, Yang (2011) highlights that the impact of the Asian culture in their personality development has served them little good. In real sense, he laments that the Asian culture has led to the development of multiple stereotypes that serve as setb acks for people of Asian descent to succeed. Yang highlights that most of the Asian American score good grades and secure position in prestigious institutions within America. He highlights that the Asian culture of hard work and devotion makes them successful in school. However, multiple stereotypes associated with the Asian Americas have served to deny them chances in the workplace that conform to their academic achievement, making them, ‘paper tigers’ with impressive certificates but lacking opportunities. He highlights that such stereotypes have only served as a ‘black ceiling’ preventing many Asian Americans that they rightly deserve from their academic qualifications. He present nine examples and profiles of Asian Americans, and reveals how Asian attributes and stereotypes associated with the Asian American have denied them chances in the workplace and in relationships. Yang describes Asian Americans as ‘bananas’, highlighting that they ar e Asian on the outside and white in the inside, but is keen to mention that the two sets of cultures are incompatible. However, if circumstances are to prove different for any of the Asian Americans, they have to follow the advice that the author presents of having the willingness to do things differently. A change of attitude for the Asians, and their determination to overcome the stereotypes that pull them can serve help them become outstanding individuals. It is possible that the strength of ties described by Malcolm will be of critical importance to Asian Americans (Yang, 2011). Yang’s critique has given rise to a heated debate in the society. It becomes questionable what Asian Americans should do different in order to succeed. Apparently, they are doing well in academics, but are not securing jobs as expected despite their qualifications. Should Asian Americans abandon Asian values and adopt attributes defined by then dominant American culture? Gladwell Malcolm mentions in his essay ‘small changes’ that one should try to be different. Asian Americans are yet to experience full integration into the American culture. Although they live and school in America, their Asian aspects have remained evident. Evidently, Asian Americans can work together towards developing ‘strong ties’ as defined by Gladwell. Such strong ties will help them overcome the black ceiling established by the lack of complete integration into

Protective security research project Assignment

Protective security research project - Assignment Example The study found out that most of the security firms and Close protection Officers were in favour of including a compulsory physical fitness test as a pre-requisite for SIA front line license award. With all the technological advances being made in the world today, security is being recognized globally as one of the areas which has greatly benefitted from these developments while at the same time suffered from it. Many people are becoming more aware of the security risks they face everyday. They seek the services of Close Protective Officers (CPO) who basically offer security services to anyone who feels that he/she is at risk and therefore in need of security services. As the need of security services increases, the effectiveness of CPO’s is coming under close scrutiny. It has been noted that physical fitness is one of the key areas that has the potential of increasing the overall effectiveness of CPO’s. In order for an individual to practice as a CPO, he/she has to be licensed. Security Industry Authority is the body mandated to award licenses to individuals who meet the criteria. Among the requirements for the award of a CPO license is a clean criminal record a nd undergoing CPO training. This study was conducted with an intention of evaluating whether CPO’s need to complete compulsory fitness tests in order for them to gain their Security Industry Authority (SIA) front line license. A brief background at this point would be of great value as it would assist contextualize this study. The Security Industry Authority (SIA) is a Non-Departmental Public Body (NDPB) that was established under the PSIA Act of 2001. It is an independent body that has the mandate to license all the individuals who meet the criteria for licensing. Any individual who wants to work as a front line operative, they must have a clean criminal record, undergo an identity check and a competency

Four Geographic Traditions Research Paper Example | Topics and Well Written Essays - 1250 words

Four Geographic Traditions - Research Paper Example As such, the core definitions of each of these traditions will be discussed as well as a level of analysis performed on which tradition speaks best to which particular aspect of geographical analysis. What is noteworthy before delving into a firm and functional definition of each of these four traditions is to understand that the subject of geography has always, since its inception, been focused on the art and science of definition. Without definition, geography would have but a few actionable uses. In this way, it is important for the reader to understand that each of the following four approaches that will be discussed should be viewed within just such a prism. Although one is not superior to all of the others at all time, each in their own way can provide a useful tool of analysis which can help the reader/researcher to draw a level of inference on specific research questions and can help to shine a valuable level of insight into key determinants that would otherwise not be able t o be fully answered with the application and/or use of another of the traditions. Similarly, although each of the four following traditions are still in use within the community of geographic research and scientific studies, some are used to a greater and more affective use than others. Additionally, as the field grows, evolves, and advances, some of the four will no doubt decrease in overall performance; however, this unavoidable decrease of some of these traditions is no reason not to consider the fundamental determinants that have sought to define the way in which the field has progressed and continues to define itself up until the current juncture in time. Naturally, from the aforementioned list, the first of these traditions that will be discussed and analyzed is that of the spatial tradition. The spatial tradition is perhaps the best known and the most common of historical geographic traditions in that it seeks to define a given region based solely upon a firm differentiation of what is â€Å"other† and what is not. Although this tradition is perhaps the oldest in historical terms of implementation and usage, the fact of the matter is that is has continued to grow and develop throughout history (Pattison 3). As a function of this, the tradition has grown to incorporate computerized mapping (i.e. GIS and the like), quantitative techniques and tools for the representation of otherwise abstract geographic terms, aerial photography, and a litany of other spatial analysis tools that have helped to define, group, and differentiate otherwise indistinguishable determinants from one another within the realm of geography and geographic research and interpretation. This â€Å"oldest† of traditions continues to evolve and incorporate the different aspects of technological advancement that have manifested themselves throughout society and the sciences. As a function of this growth, the spatial tradi

Threats to Prosperity and Stability of Developed Countries

Threats to Prosperity and Stability of Developed Countries Adrian Ma Over the past few decades many developed countries have taken the wrong steps to maintain peace with foreign states and have substantially increased the size of their government. Consequently, it becomes detrimental to any countries’ prosperity and stability; economic freedom is proportionate to size of government and war always affects the civil and moral progression of a society. When a government ignores the notion that â€Å"the individual† is the basic unit of social analysis, then the citizens cannot live life to their fullest potential. The problem perpetuates as more and more youth are becoming liberal because they are also becoming more liberal than the previous generation. The ongoing growing concept of liberalism is determining a lot of age groups to openly seek out help from the government and this strips away the dignity of each individual entailing rights and responsibility. According to an article, the average annual income per household in 2007 was appro ximately 53,000 and in 2013 it dropped to 48,000(Economist’s). The percentage of extra income the average person makes also made a noticeable drop from 5 to 4 percent meaning that it would take 5 extra years for them to double their income. This is an indicator that societies’ focus has transitioned from setting goals and seeking out to excel in certain areas to getting paid to support their financial situations, simply because of the expectation that the government is going to solve their problems. Individuals are the root of any prospering and stable economy, not the government. One top of government programs killing individualism, they also destroy millions of jobs. If citizens are constantly required to pay more and more taxes every year for government programs, not only will their financial situations get worse but competition will drastically decline as well. At the time government wasn’t involved in healthcare, it was cheap because private sectors fought to keep their businesses alive by competing with others and that factored in by lowering prices. All of these amazing â€Å"benefits† that the government forces insurance companies to provide us must be paid for by somebody and it’s those of us who aren’t in any allocations, work for the government, or have lobbyists to get us exemptions. Let’s look at Obamacare; there are so many faults because it tries to make every person happy. It centralizes on ensuring that people are covered rather than addressing the cost of care in the first place. It doesn’t benefit th e youth because they tend to be healthier and they don’t need as much coverage as the older age groups. It also increases the cost of everyone’s insurances because insurance companies are required to cover sick individuals. Healthcare in 2002 for a family of 4 cost approximately 9,235 dollars per year and after the government got involved it rose to a staggering $20,728 in 2012 (Milliman Medical Index). Another problem with government expansion is that it causes inflation; the increased debt ceiling from overspending and the Federal Reserve is just a cataclysmic combination for stability. Here’s the dilemma, whenever the government needs money instead of issuing their own notes backed back their own credit they issue treasury bonds, then they sell these bonds to the Federal Reserve which buys them with money they created out of thin air. The money that the Federal Reserve creates later goes to the government meaning it has to pay interest on the money the Federal Reserve lends to the treasury. This means that there will never be enough money in circulation to pay off the debt. The liquidation of debt is what makes an economy prosper and stabilize. Looking back at how the depression ended, a number of people believed the gold standard was the gold standard but they were mistaken, the countries that were able to liquidate their debt first got out of it. After World War 2, the g overnment cut 60% of the budget, 30% on tax rates, and around 9 million military personnel came home causing all the bad debt to be liquidated, hence, ending the depression. The constant printing of money may have bailed out major corporations during the depression but the problem originated from a governments belief that they can run the economy. The price stability reduces and a side function of an unstable dollar is the large swing in consumer prices. Another issue that developed countries overlook is the importance of economic freedom, it is more than just the freedom to buy and sell products and services. It allows us to be free in our interactions with other people. It also empowers people to travel, to say what they want to say, and to do what they want to do. It is about being free to make our own choices. A lot of those things are positive indicators of a healthy country and for a government to interfere may form impairment. Based on facts, the more economic freedom country has indicates that everyone is better off. The economic freedom of North America Index indicate that states with more economic freedom have higher growth rates of the economy, 4.6% GDP in the 25 least free states and 5.5% in the 25 most free states; lower unemployment rates, 5.5% in the 25 least free labor markets and 4.9% in the most free labor markets; less debt per GDP than states that are less free, 16.2% in the 25 states with least tax freedom and 15 .7% in the 25 states with the most tax freedom (2000-2009, LearnLiberty). All of these things people associate with economy health are also associated with economic freedom, and the same phenomenon also occurs with the countries of the world. The most economically free countries have GDP’s per capita that are about 10 times the size of less economically free countries. Some of the counter arguments I’ve encountered is that the GDP per capita only measures average income but it is untrue. It’s possible to have a country with a small number of elite rich people and a large number of destitute people, and if people examine inequality measures what they should see is that the countries that are more economically free also have more equitable income distributions. Economic freedom is not only associated with higher income levels on average but it is also associated with more equitable income distribution. Skeptics have argued that economic freedom achieves economic i ncome because of exploitation, people and the environment. Based on the data, they are wrong. On average women in more economically free countries have more gender equality and child rates tend to be a lot lower. Some may say that child labor rates are lower in economically free countries because they are more prosperous and can import from but they are also mistaken. The same phenomenon occurs even amongst the poorest countries; the least free poor nations have 40% child labor rates and the freest poor nations have 37% child labor rates (2000-2009). The biggest threat to the prosperity and stability of any developed country is war and the longer it is the more it will cost. An administrator in the Bush Administration told American taxpayers in a hearing before the Iraq War that it would only cost 1.7 billion dollars. According to numerous sources, the wars in Afghanistan and Iraq will now cost taxpayers roughly 5 trillion dollars, and that isn’t even taking into account the long-term medical care and disability compensation for service members, veterans and families; military replenishment and social and economic costs; expensive repairs to a force depleted by just perpetual fighting. More problems arise with government healthcare because the government owes it to them for fighting their wars. In the United States alone, a quarter of a million troops have suffered traumatic brain injuries (TBI) putting a bigger toll on the government healthcare system. Even the war on drugs also threatens the stability and prosperity of a country but that’s another issue. Governments should learn to take care of their own people before trying to solve other people’s problems. Our ability to cooperate, to help each other out develops when there is no conflict and when individuals have a smaller reliance on government. They recognize themselves in each other and are programmed for compassion. All of those things make them stronger, faster, and smarter. It relates to why communism doesn’t work as well as it should because human beings are biologically engineered to be competitive in nature and freedom drives then to work harder for success. If a government takes away our rewards and shares it with others then a specific majority will feel less rewarded, thus, competition and innovation is automatically promoted by limiting the government’s role in an economy. In a free economy, people will constantly find ways to create and offer better values to customers than their rival firms. Competitors that do well focus on reality, inventions, innovations, and methods opposed to rivals per se. Citizens are given more of an inclination to be independent, unconventional, and rebellious towards societies’ opinions and norms. It is no wonder why most of the greatest discoveries came from the countries that are the most free. Works Cited Dominguez, J. (1995).
