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 ...

Introduction

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 ...

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 ...

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 results ...

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 ...

Sampling is the process of selecting a group of subjects to act as a representation of the entire target group. The selected representative portion of the population is called a sample, and it upon which generalizations of the research findings is done to apply to the whole target population. There is one principal way through which a sample might not be a representation of the entire population. This occurs when randomization is not done during the process of compiling the sample. It should be noted that randomization is the key to building an effective representative sample for the study. ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 ...

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 be ...

“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 ...

Introduction

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 ...

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 ...

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 ...

Critiquing Quantitative and Qualitative Studies

Several research techniques are available all with the aim of achieving precise data or information or data about something. Quantitative technique, sometimes referred to as true science, involves the use of mathematical and statistical methods in the analysis and drawing useful information from a specific set of data (Davies, 2009). On the other hand, qualitative is a type of technique used to study behavior and habits portrayed by humans under different environments. The critique is aimed at juxtaposing the two techniques involved in the field of research with critical analysis of the two methods.

Since the publication of Titchener’s article in 1898 (Titchener, 1898), psychology has had the opportunity to evolve as an independence branch of science and as you say almost by the end of your post, it gave birth to schools of thought such as psychoanalysis and humanism. The attempts of Titchener and his colleagues to organize and give form to this new science were not in vain. I found it very interesting how he managed to make an analogy with the biological sciences. Although the main article focuses on structuralism -or experimental psychology- and descriptive psychology –the branch that ...

During Philip Zimbardo’s simulated prison experiment, there were many ethical problems at hand. The actual severity of these ethical issues was discovered only once the experiment had begun, after some of the participants acting as prisoners had to be removed before the end of the experiment. After the experiment was over, it was determined that some of the participants acting as prison guards had exhibited sadistic tendencies throughout their role. Those acting as prisoners were all severely emotionally traumatized from the sadistic actions exposed to them by the prison guards. Additionally, the physical conditions in which the prisoners ...

Experimental design for the nursing research proposal

This research uses quasi-experimental design. Quasi-experiments are studies that aim at evaluating interventions without using randomization. These experiments aim at establishing a connection between the intervention and outcome (Sullivan & Garland, 2010). The use of the quasi-experiment design is the most appropriate since the intervention often cannot be randomized in a hospital or public health setting. A quasi-experimental design offers an experimental design in which participants are not assigned randomly into different groups (Maltby, Williams, McGarry & Day, 2014). A quasi-experimental design is more frequently implemented than the randomized experiments.
Quasi-experimental designs are universal in the staffing levels of nursing staff ...
