The Ellen Roche case is a case wherein a healthy volunteer participated in a National Institutes of Health funded research on the natural defenses of healthy individuals against asthma. The purpose of the study is to “gain a better understanding of the pathophysiology of asthma, specifically the mechanism of airway hyperresponsiveness”. Under the experiment Roche and the other subjects are required to inhale hexamethonium, a ganglionic blocker. The subjects will be paid $365 for participating in the experiment. After almost a month of participating in the research, Roche died due to progressive hypotension and multi-organ failure, which was attributed to her inhalation of hexamethonium.

Many scholars have become increasingly interested in comprehending why people who are liars tend to be more creative as opposed to those who are honest. Consequently, both dishonesty and creativity encompass breaking of rules thus shifting from the norm (Ariely 2012 p 76).Various studies have been undertaken with the aim of attaining an in-depth understanding of this phenomenon. The paper will explicitly evaluate the relationship between creativity and dishonesty.

Thus, the five experiments that were undertaken established that the cheaters were more creative as compared to the non-cheaters. The first experiment involved a hundred and fifty-three individuals that were ...

1. The title of the article is "Is Noise Always Bad? Exploring the Effects of Ambient Noise on Creative Cognition". The purpose of this research is to determine the effects of low, moderate, and high noise levels on creativity within a consumer context. The authors of the study propose that low- and moderate-levels of noise enhance abstract thinking processes in creative individuals. The researchers also propose a mechanism called processing difficulty -- or "disfluency" -- which causes a higher "construal level" that, in turn, causes individuals to engage in more abstract thinking. Furthermore, individuals who are more-predisposed to being creative, the researchers ...

Bioengineering has been around for some time now, and ever since its introduction, it has been the subject of never-ending controversy claims, myths and misconceptions. Many believe consuming genetically modified organisms, the most widely known product of genetic scientists, is harmful. In order to alleviate these concerns, many laboratories around the world were tasked with conducting experiments to prove once and for all GMO is safe for human use. Yet other scientists began independent research into the long-term effects of GMO consumption. In many cases, published findings contradict one another, which only adds to the controversy and further divides ...

1. The City of Bell.

Humans are by nature susceptible to mistakes. In the case of Bell, the annual salaries of the appointees were raised to such levels that the city manager was paying himself $800,000, which was unethical. Citing the examples of Alpha, Bravo, and Charlie Services, the attitude of Cairns is deplorable, as he kept awarding contracts only to Alpha Services despite the numerous recommendations. Also, Cairns attitude is very much against the code of ethics of ASPA, and his racial bias and suspicions on his possible dealings with Alpha casts a lot of doubt on his professional behavior.

When Martin Luther King Jr. was assassinated in July 1968, grief and frustration broke across America. Martin Luther King Jr. stood for equality and was an anti-racist crusader. Martin Luther King Jr.’s death had an impact on one person in Ireland, thousands of miles away. Jane Elliot, a third-grade teacher wanted to set the records straight, as she said that she has talked about racism from the first day of school. She wanted to teach her third-grade students about Martin Luther King Jr., and knew that there was only one way she could do that. A Class Divided is ...

The experiment aimed to show that Blm10 protein elevates the turnover of proteasomal substrate through an active gating mechanism. This was to be done by showing that Blm10 enhances degradation that is proteasome-mediated in vitro using hypophosphorylated unstructured tau-441 as the substrate.

The objective was achieved using various stains such as BY4741, yMS63, yMS94, yMS122b, yMS131, yMS152, yMS159, and yMS476 among others. To start with, the proteasomal activity was assayed by determining gate opening in yeast CP/20S proteasome by the C terminal peptides. Phenotypic analysis was also done by growing the stains overnight in YPD and diluted to a density ...

Introduction

In my experiment, I used the sequential design as my experimental design. It guided me to agree with the hypothesis,” that emotionally loaded words like “sex” and “prostitute” must be exposed for a longer time to be perceived than neutral words. I conducted surveys so that I could come up with the findings and the conclusions of the experiment. The dependent variable in the experiment was the threshold in which the loaded words are used. The independent variable is the time taken in the surveys that I conducted.

The sequential experimental design requires the researcher to complete a ...

Introduction In his article, John Derbyshire wrote about the challenge of improving the children’s academic performance. He documented that a few years ago, New York City Mayor took the Rand Corporation’s service in raising the students of public schools’ examination score by providing cash bonuses for those teachers who will have an improved class. As he continued with his article, Derbyshire used different styles in writing to persuade his readers. Based on his attempts to persuade his audiences, rhetorical strategies were used such as logos, ethos and pathos. However, there were clear manifestations of logical fallacies in ...

The purpose of this experiment was to observe collisions between two carts, measure energy changes and classify the collisions. It was hypothesized the momentum would be conserved during the collisions.

- Consider a head on collision between two billiard balls. One is initially at rest and the other moves towards it. Sketch a position vs. time graph for each ball, starting with the time before the collision and ending a shot time afterward Before collision, ball 2 moves with a constant velocity towards ball 1. Therefore, its position changes with time while the position of ball 1 does not change. After elastic ...

There is a time when advertisers need more than descriptive research to understand consumers current behaviors and attitudes. They sometimes require an understanding of cause and effect, which is obtained through experimental research in which an advertiser alters something in the consumer’s environment, or product in order to see what would happen. The goal of an experiment is usually to determine the effect of changes in one area on one or more other areas. An experiment is used to vary the amount of advertising placed in particular markets to determine how advertising weight affects target audience, advertising awareness and ...

Research is critical to the advancement of any field, whether it is engineering, medicine or even management. However allowing researchers to conduct experiments without any supervision or without checking in with some regulatory authority might put them and others around them at risk. The premise of this paper is to argue that research regulation is necessary to ensure that civil rights of those involved with the experimental safeguarded. In the five case studies that were outlines for review, one common factor among them was that in cases when researchers were given freedom to perform experiments they put the ...

In 1928, the penicillin was discovered. It was a powerful medicine with numerous possibilities to cure diseases. Doctors all over the world tried to find out new ways of using it. One of the theories stated that the penicillin could treat and prevent the syphilis and other sexually transmitted diseases. In order to prove this theory, the Guatemala Syphilis Experiment was begun. This experiment took place between 1946 and 1948. It was led and sponsored by the United States Public Health Service under the guidance of the physician John Charles Cutler. The Guatemala Experiment was one of ...

Abstract

All cells in a living organism require energy to drive various cellular activities such as transport of molecules and movement among others. The rate of cellular respiration may be affected by the substrate concentration, pH level and enzyme concentration among other factors. This experiment aimed to study the rate of cellular respiration in isolated mitochondria under different conditions. It was hypothesized that if the concentration of the substrate is increased then there will be an increase in the rate of cellular respiration. Mitochondrial suspension was used as the source of succinate that was used as the substrate. The level of ...

The notion good people change their behaviors when put in an evil environment was experimented by a team of researchers led by Dr. Zimbardo in the infamous Stanford Prison. Twenty- four volunteers were chosen to stay for two weeks in prison where they would be subjected to the harsh prison environment. For their participation, the volunteers who were divided to two groups, the prisoners and the guards would receive $15 a day as compensation (Zimbardo 244). Prisoners underwent extreme punishment, degradation and depression as they wholly started to believe they were actual prisoners. The guards enforced and abused their newly found ...

CONTROLLING EXTRANEOUS VARIABLES

CONTROLLING EXTRANEOUS VARIABLES

Dependent variable is the variable that is measured by the experimenter.

Extraneous Variable is a variable that is not an independent variable in a study but has an effect on the dependent variable. There are two types namely: - Situation variable: This involves the environmental aspect of the study such as noise, presence of others and physical characteristics of the environment like rain and temperature. - Participant variables: This refers to variations between participants’ characteristics such as mood, expectations, intelligence among others. Extraneous variables must be controlled to ensure that the changes observed in dependent variables are due to the changes in independent variable.

Emotions can affect one's reasoning and how one makes decisions. Unless one is in control of his or her own emotions, it may be difficult to think and reason effectively. Inner emotions change a person’s moral reasoning when proving their actions. It is necessary to avoid the effect of emotions when reasoning through a difficult situation. For instance, you want to prove very important point and at the same time you are in a bad mood, angry or hopeless. These emotions will surely affect your moral reasoning to some extent. Avoiding emotions at all in making a decision may be impossible, but ...

Introduction

Mitochondrion plays vital roles in the performance of tissue. It is important, therefore, that their isolation and study are advanced to correct anomalies that arise out of the mitochondria failure. Instances of a mitochondria failure in neuronal tissue have been reported to cause anomalies such as epilepsy and ageing. Since mitochondria is responsible for the production of ATP in the cells, failure or inefficiency of these organelles causes a dysfunction in their component tissue leading to some ailment in the host organism. Many methods exist for the extraction and observation of mitochondria, some of these methods include, differential centrifugation and the ...

Most people especially in the traditional societies considered persons with mental disability as people with incurable illness. As such, people had very negative attitudes towards the mentally challenged. As such, the aspect of mental illness has been a realm of the mental health professionals such as psychiatric workers, psychiatrists, psychologists, and related fields. Following the deinstitutionalizing of the mental patients during the 1960s and ‘70s, people did not give much consideration to the subject of mental health and people with mental illnesses (Borinstein 1). The families that had members with mental illness treated the condition as an issue that was ...

No man is an island. This quote serves as a reminder that we do not live in isolation. As stated by Aristotle, human beings are social animals who need daily social interaction with other members of the community and that to be self-sufficient and not partake in the society is distinctive of either a beast or a god. Because of this frequent interplay among members of the society, creating laws and empowering legal authorities became a necessity in order to establish order. These laws are meant to impose control and limitations over what individuals can do to avoid interfering with the rights of ...

An experimental design is a plan that guides information gathering where variations are present. The plan shows how the experimenter will present or withhold the experimental event. The experimental design is important when conducting experiments because it has a direct effect on the results arrived at in the end. An effective experimental design should be able to rule out alternative explanations of the findings. Experiments are conducted in environments where several factors exist that can affect the impact of the treatment on the subjects. The design should allow the experimenter to confidently attribute the behavior change to the presence or absence ...

Race comprises that are thought to different from each other on the basis of imagined or real physical of the individuals differences (Macionis, Jansson & Benoit, 2012). The experiment in The Class Divided is very significant; it is an effectual representation of the fact that people themselves are responsible for fostering the racism. This experiment has pointed out towards the fact that people belonging to different races are not separated by the physical boundaries, but they are actually people who themselves are responsible for keeping the boundaries and separating people on the basis of races. Further, this experiment has made ...

- While conducting research, scientists need to understand the main variables within their experiments. Define and provide an example of both an independent and dependent variable. In any research there are mainly two variables; the independent and the dependent variables. Any scientist needs to understand the variables very well because of the following reasons. First the variable determines the type of methodology that can be used in the study. What this means is that the type or variables would determine how the whole research is carried out. For example, a variable might have qualitative or quantitative aspects that would ...

“There are only two ways in which humankind can produce knowledge: through passive observation or through active experiment.” To what extent do you agree with this statement? The argument whether knowledge can be attained through passive observation or active experiment defines the meaning of knowledge. When you look at two people argue, philosophers argue this is passive knowledge of the argument as you are not actively being engaged in the argument. However, as you argue with your friend, this is defined as active knowledge since you are in a position to experience the argument and get to know something ...

One of the most important part of protein assay is the determination of protein concentration. There are diverse methods used for protein concentration determination, but the most widely used are the spectroscopic methods of analysis or spectroscopy. Spectroscopy usually involves the determination between the correlations of the degree of interaction of light with the analyte, which is the proteins in this particular experiment. There are different types light to analyte interactions and one of these is the absorbance of light or electromagnetic radiation by the analyte. This type of spectrometry is called absorbance spectrometry.

IntroductionYeast is a single-celled organism and is a type of fungi. Yeast has been used for centuries as the driving force behind the process of fermentation, which enables dough to rise into a loaf of bread. To make a loaf rise, yeast converts sugar (C6H12O6) and oxygen from the air (02) into carbon dioxide (CO2) and water (H20). When no oxygen is available, yeast will switch to an alternative pathway that does not need oxygen.Yeast metabolizes sugar (C6H12O6) to make carbon dioxide gas (CO2) and ethanol (C2H5OH) as end products. This carbon dioxide gas produced from yeast fermentation is responsible for the airy ...

Utility and sub game perfection

Ultimatum Game is an appropriate paradigm that investigates the discord between social motives like fairness and self-interest. UG bases on the assumption that bargainers maximize their outcome. The acceptance of the smallest offer can yield high outcomes and the alternative of refusing means no outcome at all. The social utility model implies that the utility of the outcome depends on both payoffs. The study aims to identify factors that can affect the relative importance in making UG. A strong reciprocity model in the evolution of human cooperation gains acceptance because of support and experimental findings. An observation that unfair ...

A species is a collection of interbreeding populations that are reproductively isolated from other species in nature. The experiment was carried out to find out the outcome of geographically separated lizard populations. Russell, Hertz and McMillan state that speciation resulting from divergent evolution among geographically separated populations is referred to as allopatric speciation (Russell, P., Hertz, P., & McMillan, B.

There are several assumptions in psychological testing. For example, behaviorist assumption that psychology is a science and hence ought to be tested using scientific methods is one of the major assumptions. In addition, there is an assumption that people are born blank and learn all the traits they portray. The mind acquires and outputs information jus as machines and that the brain is in sections that can be identified separately. Another assumption is that behavior is acquired during childhood and can be influenced by hormones the person secretes. In psychological testing, the test seeks to establish a verdict on a given ...

This example involves a pharmaceutical company that is testing a new medication to change oxygenation levels. In one group the subjects received the experimental drug while in the other group the subjects did not receive the drug. Subjects in each group were then measured on oxygenation levels. This is not a reversal design in which the groups then are switched in terms of condition. Therefor it is an independent samples test, comparing the means for two different groups. The question posed is whether the mean oxygenation level for Group I (treatment group), is the same as the mean oxygenation level for ...

Discussion Questions: Neural Mechanisms and Animal Behavior

1. There are different factors to consider when studying how animals behave and adapt to their surroundings. Different animals have their respective perceptions and their way of encountering information, so the concept of dependent, independent, and controlled variables might come into play (Mackenzie 41). Therefore, examining the perception of each animal may depend on changing situations. One variable important in the study of animal behavior is their circadian mechanisms. Any formulated hypotheses and experimental findings could be critical in studying the adaptation of animals and their methods of stimulus filtering that occur at specific intervals. The concept of personification ...

Introduction Modern psychology relies primarily in experimentation. Since animals and human beings constitute the subjects of experimentation, precautionary measures continue to improve the process of experimentation while producing the less possible amount of damage to animals or human beings. Thus, different models, approaches and theories keep coming up as to how to do experimentation in psychology for furthering research. Danziger (1985) writes that the experimentation in psychology has evolved as a social institution (Danziger, 1985, p. 133). Similarly, Schultz (1970) recognizes that modern psychological experimentation is the result of a long history of developments that have shaped this science ...

In the realm of the scientific study of psychology and of human behavior in general, there are numerous cases and experiments that may be deemed to have such lasting effect in the landscape of academia to be called landmarks. A few of these we have discussed in class, such as Asch’s conformity experiment, Milgram’s remix experiment, the auto-kinetic phenomenon, and Jane Elliott’s eye color experiment, may be said to be staples in field of social psychology. However, one other, equally-important experiment may be seen in Philip Zimbardo’s Stanford prison experiment. The case, conducted on students ...

(1.1) This experiment is about determining the effect of angle of inclination in the acceleration of an object. The independent variable is the angle of inclination of the slope of motion; the dependent variable is the acceleration of the object.

Hypothesis

(1.2) The angle of inclination of the slope is directly proportional to the acceleration of the object. Without initial applied force, the only acceleration of the object would only be due to gravity. Thus, the relationship will follow the equation: a=gsinθ Where a is the acceleration of the object, g is acceleration due to gravity, and θ is the ...
