...findings in this experiment did not match our original hypothesis. In fact, it was our belief that the pill bugs would spend most of the time in the leafy mixture making it their most preferred environment. The experiment led to the disprovement of our hypothesis. From the very start of the first part of our experiment, we realized that the pill bugs were very fond of the soil substance, much more than the leafy mixture. Based upon the time that the pill bugs spent in the soil during the individual trial, it was clear that the soil was their preferred environment. In fact, each bug spent on average, 42 seconds in the soil during each one minute period. This average correlates to the fact that the combined totals of the time in which the pill bugs spent in the soil substrate was right at 70% of the entire individual trial. The question of what environment the pill bugs preferred the most of soil, sand, or a leafy mixture seems to have been solved through this experiment. Through the use of the three different environments in close proximity, we were given the best opportunity to analyse the decision making of the pill bugs. This determinization of what attracts these bugs can serve helpful to those...

...In this experiment, we were trying to determine the taxis and kinesis of the pill bugs. After the experiment and observation, we determined that pill bugs prefer dark areas and require moist in order to survive. Even though all the pill bugs in all test were moving you could see some more random movement and revolution in the dry area compared to the moist area. We observed that they like the dark area and stay close to each other which show they need humid area in order to survive The purpose of this experiment was to determine what environment the pill bugs prefered more, the moist or dry. While performing this experiment we were looking to see what conditions they desired more, the moist or the dry. While observing we could see how they behaved in a dry and dark area and also the moist and dark area, how they interacted with each other,and how many were active out of all five. To have a better understanding of this lab we had to know what pill bugs are before perming our experiment, and we found...

...This data does not support the hypothesis that pill bugs would spend more than 50% of their allotted time in the moss than the rocks. Rather, the data shows the opposite: both pill bugs preferred to spend more time by rocks than moss. Pill Bug #1, specifically, spent an average of more than 50% (66.7%) by the rocks. Furthermore, the moss only accounted for 20% of both the pill bug’s location in the five minutes given. During the observation, each pill bug seemed to have a unique behavior in their movement that differed from each other. Pill Bug #1 seemed to move back and forth the two sides but eventually settle in just the pebble area. Pill Bug #2 moved in a more active manner compared to Pill Bug #1, moving constantly back and forth between the three different areas throughout the entire 5 minutes....

...This experiment helped us understand more about pill bugs and it's supported our hypothesis that the pill bugs would prefer the moist environment over the dry environment. The only thing we failed to state the fact that the pill bugs would not prefer to be in the dry area, this is shown by how much they wanted to get out of the new environment we placed them in. Our test result shows that the pill bugs prefer the moist area over the dry area more and also a dark area over a place with light. Based on our results test when adding water drop the pill bugs in the third test of the moist area when we added 15 drops of water they have more random movement compared to the 2 and 10 drops. This is a proof that even though they like moist area pill...

...Taxis is a directional movement that veers away from or toward stimuli while kinesis in the context of this lab refers to non-directed movement that is made in response to stimuli. This isopod, which is a sow bug (Oniscus sp. / Porcellio sp.), generally moved to and stayed in the chamber that was under the foil upon the introduction of the lamp. In the darkness, the isopod was considerably more active than in the light. Though Morris’s (1999) study did not explicitly focus on sow bugs and pill bugs, his research is based around isopods and his results support the idea that this was an example of kinesis, in that the presence of the light in one chamber decreased the bug’s activity in that area. Since negative photokinesis describes the increase...

...taking this class now is the best time for me. This course is preparing me for what college classes are like. I am also learning a lot about college applications and what to do in my senior year. The most difficult task in this class so far was the very first lab that we were assigned to do in the summer. It was hard for me because I did not like writing lab reports and I am not good at them. I also did not like working with the pill bugs. My proudest achievement in this course was when I got an 84.5 on my midterm. I studied for a long time and was in fear of how difficult it was. After I took the test, I thought I had failed. I was happy when I saw that I had passed. I think I still need to work on my studying habits. I need to study more before a test and actually read the textbook instead of skimming it for important information. I am a visual learner. I feel...

...Computer crime Computer Crime Definition A computer crime is any illegal action where the data on a computer is accessed without permission. This access doesn't have to result in loss of data or even data modifications. Arguably the worst computer crime occurs when there are no indications that data was accessed. Computer crime is often attributed to rogue hackers and crackers, but increasingly organized crime groups have realized the relative ease of stealing data with relative low-level of risk. Government organizations are also rumored to be involved with hacking in to computer systems, but the legality of such actions is far too grey an area to be discussed here. Computer crime, or cybercrime, refers to any crime that involves a computer and a network, where the computers may or may not have played an instrumental part in the commission of a crime.[1] Netcrime refers, more precisely, to criminal exploitation of the Internet.[2] Issues surrounding this type of crime have become high-profile, particularly those surrounding hacking, copyright infringement, child pornography, and child grooming. There are also problems of privacy when confidential information is lost or intercepted, lawfully or otherwise. On the global level, both governments and non-state actors continue to grow in importance, with the ability to engage in such activities as espionage, financial theft, and other cross-border crimes sometimes referred to as cyber warfare. The international legal system is...

...home. Insects and other disease spreading pests can threaten the health and lives of families and individuals in a community, many lethal diseases such as Lyme disease, bubonic plague, dengue fever and malaria, for example, are spread by biting or stinging pests. The pests include all insects, example, the mosquito is responsible for spreading malaria, as well as ticks which spread Lyme disease. The citizens of first world countries typically tend to become infected through the bite or sting of insects and bugs while they are abroad. Indeed, travelers to exotic locales are often affected by nasty diseases transmitted by insects or bugs and bring such disease home with them. The greatest dangers lurk closer home and one need not travel across the world to face tiny pests. Many local insects and bugs in North America can cause serious diseases. Therefore, protecting the entire family through the prudent use of good quality insect and bug repellents is a necessity. Insects and bugs as vectors Each year, millions of people die from diseases transmitted by insects and other pests acting as vectors - an organism that acts as a host or carrier of some minute pathogenic organism that it transfers or transmits to a human host. In the case of malaria, for example, the mosquito is a vector, while malaria is actually caused by the protozoan parasite plasmodium. The human being is the final host. Not all diseases passed on by...

"Combines how-to with be-smart for an audience of job seekers, interviewers, Wired-style cognitive science hobbyists, and the onlooking curious. . . . How Would You Move Mount Fuji? gallops down entertaining sidepaths about the history of intelligence testing, the origins of Silicon Valley, and the brain-jockey heroics of Microsoft culture." — Michael Erard, Austin Chronicle "A charming Trojan Horse of a book While this slim book is ostensibly a guide to cracking the cult of the puzzle in Microsoft's hiring practices, Poundstone manages to sneak in a wealth of material on the crucial issue of how to hire in today's knowledge-based economy. How Would You Move Mount Fuji? delivers on the promise of revealing the tricks to Microsoft's notorious hiring challenges. But, more important, Poundstone, an accomplished science journalist, shows how puzzles can — and cannot — identify the potential stars of a competitive company....

We think we're making smart, rational choices. But are we? In a series o f illuminating, often surprising experi ments, M I T behavioral economist Dan Ariely refutes the common assumption that we behave in fundamentally rational ways. Blending everyday experience with ground breaking research, Ariely explains how expectations, emotions, social norms, and other invisible, seemingly illogical forces skew our reasoning abilities. N o t only do we make astonishingly simple mistakes every day, but we make the same types of mistakes, Ariely discovers. We consistently overpay, underestimate, and procrastinate. We fail to understand the profound effects of our emotions on what we want, and we overvalue what we already own. Yet these misguided behaviors are neither random nor senseless. They're systematic and predict able—making us predictably irrational...
