Stress can occur to any human being. Stress is a normal psychological and physical reaction to the demands of life particularly to traumatic incidences. The process of induced abortion or natural is a stressful time for many women (Adler, N. E., David, H. P., Major, B. N., Roth, S. H., Russo, N. F., & Wyatt, G. E. 1990, p. 41). The stress can occur before and after abortion. In this study we are focusing only on post abortion stress. Women who undergo abortion natural or induced are likely to experience acute stress i.e. Acute stress originates from the demands and pressures of ...

Violence Caused by Video games

Violence Caused by Video games

In the case study the verdict is against the video game company. The jury says that violence shown in the video games is very much dangerous and it can instigate children to react in a violent manner.
Thus, the scientific study of the harmful effects of watching violence on video game and aggressive behavior has now grown to be conceptualized it as an important risk factor understanding this, as a set of conditions in the individual or in the environment that produce an increase in the probability of developing a particular problem as in this case, ...

A social norm is an accepted behavior in the society. Norms have been gradually developed in the society because of interactions among people who live together to form a society or community. Examples of norms are washing hands before eating. Looking at someone when he or she is speaking to you, giving someone his or her personal space and many more. Norms vary from society to society. There are societies that consider a certain mode of behavior wrong. However, when we observe another society, the specific behavior is accepted. For instance, in an American society, shouting when calling somebody is unacceptable. ...

- Introduction
Motivation is a behavioral concept used to illustrate momentary effects of administration of a conditional operation. A motivating operation was initially developed in order to show the results of changing the normal conditions of an organism by either increasing or reducing the operant can either increase or reduce its effectiveness. Motivation can therefore be defined as a measure of effectiveness on change of amount of a reinforcer. This operation affect whether an organism wants or does not want a stimulus. Motivating operations that result increase of effectiveness of a stimuli are referred to as establishing operations (EO). On the other hand, those ...

The Tuskegee Health Experiment: A Question of Bureaucratic Morality? Were there precise moral and ethical issues that the case presents? Are they dependent upon race, color economic status, and/or geographical location? Why or why not?
The government bears the responsibility for ensuring that all human rights are well protected. In relation to the Tuskegee experiment, both the government and health organizations are supposed to conduct researches that meet moral and ethical standards.

Generalizability

Husserl distinguishes procedure of generalization and specialization of procedures of formalization and deformalization. Generalization is the transition from the spirit to higher on the tree of generic entities and formalization - a "meaningful generalization in a purely formal logic." For example, the transition from "red" to "sensory quality" is a generalization, and the transition from "red" to "adjective" or "chalk" to "beings" or "existing" is a formalization. Similarly, deformalization is filling the empty logical form something meaningful and specialization - descent of the tree of generic.
Examples of both we find in mathematics. Example of formalization: the transition from an intuitive understanding ...

The experiment examines the effect of acid, base, caffeine, and microwaves on the germination of Raphanus savitus seeds.
The main purpose of the experiment was to test the negative and positive effects of different environmental factors on seed germination. The data was collected after two weeks. It ...

INTRODUCTION

Understanding human beings, their thoughts, feelings, and behaviors has always been a fascination of society. While human beings, as animals, are dependent upon a certain number of biological imperatives; the most basic needs, wants, and desires. Psychology looks not solely at the physical but the psyche of human beings. They seek to understand why some people react differently to differing situations and are some behaviors able to be triggered based on a scenario or created environment. Psychology has always simulated environments in order to gauge people’s responses or to see if certain responses could be recreated. That is exactly what was ...

Effect of Light Intensity on the Rate of Photosynthesis

Purpose
The purpose of this experiment was to determine how light intensity affects rate of photosynthesis using seaweed.
Introduction
In the process of photosynthesis there is combination of water and CO2 from the environment to form oxygen and sugar, mainly glucose (Emeritus, 2010). These products are then used by the plant through the process of respiration producing water and carbon dioxide (Seeley, Stephens, & Tate, 2004).

Hypothesis

It was hypothesized that the rate of photosynthesis as measured by the number of bubbles produced increased as light intensity increased.

Methods

Results
The amount of bubbles that appeared during the ...

Abstract

Kamin blocking is a condition where animals elicit a Conditioned Emotional Response (CER) to a Conditioned Stimulus (CS) and fail to associate any other Unconditioned Stimulus (US). This study investigates if the Kamin blocking principle holds true for human subjects. Using food as a conditioned stimulus and Allergic reaction as an unconditioned stimulus, a contingency judgment task experiment was conducted on 683 participants, where they were exposed to a CS in the first stage and a combination of CS, US and a superimposed stimulus in the second stage. In the third stage. Participants asked to predict the probability of the superimposed stimulus eliciting the US and compared ...

Abstract

A concept perpetuated by many different motivational experts and self help experts states that if a person wishes to achieve success there are simple steps that can be taken to effect such a goal. A common one is positive visualization. A series of four experiments were conducted to test the hypothesis that positive visualization could increase the likelihood of desired outcomes in different endeavors. The results of these experiments showed the opposite effect. Positive visualization actually drew ambition away from the very activities that were required to ...

As humans, we enjoy experiencing pleasure. Pleasure, in itself, is reinforcing since we will repeat an action that resulted in pleasure over and over again for as long as it continues to bring us that positive reward. Sometimes the things that we enjoy most are always pleasurable such as being with family or our favorite meal. Other times what gives us pleasure may lose its saliency so we may try to find something to replace this source or pleasure or do something to increase the intensity or the overall effect of cause such as when we need to use ...

Reason for doing the research

The goal of the paper was to investigate whether pharmacological treatment with the pan- Peroxisome Proliferator-Activated Receptor (PPAR) agonist bezafibrate would correct a deficiency of PPAR--coactivator 1α (PGC-1 α) and apply beneficial effects in a transgenic mouse having Huntington’s disease (HD). A number of mice with a deficiency of PGC-1 α were fed on a special diet comprising of bezafibrate and another group was left untreated. The mice were examined for a long period and then euthanized with CO2 inhalation. They died after some time and were dissected with several internal parts (brain, muscles, liver etc) being examined.

Hypothesis

Introduction

People influence the behaviors of those they come in contact with in many different ways. One of the most important ways is that the presence of others set expectations of others. In fact, people’s behavioral patterns are not random, but they behave in different ways based on the expected response of the society. Within each social situation, there is a given set of expectations regarding the appropriate ways in which people are expected to behave. These expectations often vary from one group to another. One of the ways in which the expectations of the society become clear is through ...

Abstract Research methods in social sciences have two basic categories; qualitative and quantitative methods. Quantitative research involves asking people's opinions in a structured manner in order to produce hard facts and statistics. In contrast, qualitative research is an explanatory research with the main focus being to gain insights into the helps or problems to develop a hypothesis for potential quantitative research (Cohen et al., 2010). Quantitative research is used to quantify defined variables such as opinions and attitudes, and generalizing results from a larger sample. They use measurable data in formulating facts and unearthing research patterns. Qualitative data collection methods take the ...

Following the American Psychological Association’s Guidelines

For this experiment, I am testing the theory that sleep deprivation will weaken the mind’s ability to recall certain words, inhibit word association, and disrupt the ability to recall whole phrases. I am conducting this experiment because the general way the mind works has always fascinated me but I have had a particular interest in memory, especially in terms of what weakens it. It is well known that old age can weaken the memory, but I have interest in other areas of life that can weaken the memory, such as stress, trauma, and sleep deprivation. Because I am not ...

Introduction

It has been stated that memory is a reconstruction of events rather than it being photographic (Schacter, 2001). False memory is considered to be recollection of events that never occurred. This is also called the distortion of one’s memories. There are some memories that come from dreams in that a person thinks that it was an actual real life experience (Brainerd, 2005). There are some memories that are claimed to be as a result of someone leading them to those memories, prodding and suggestions especially by counsellors and the police officers. There are other times when an event occurs but someone ...

Introduction Conditioning refers to the process whereby predictable response is made from neurological patterns that have been established through reinforcement. Classical conditioning also called Pavlovian conditioning is one of the most influential conditional theories in Psychology (Bergin &Bergin, 2012). It was put forward by the Russian physiologist Ivan Pavlov in the 20th century. It is based on the association between environmental stimulus and unlearned or naturally occurring stimulus. Classical conditioning can be used to explain my childhood fear for people dressed in nursing gear. There are four basic components of classical conditioning namely; unconditioned stimulus, unconditioned response, conditioned stimulus ...

Every year, a number of animals are locked up and subjected to tests that cause them pain and even death. This is through the animal testing procedure. Animal experimentation is a procedure whereby non-animals are tested and used to develop treatments, check the safety of products for human use, and other commercial and biomedical uses. It is estimated that, over 26 million animals are used every year in the United States for animal experiments. Animal testing is a controversial topic and like any other contentious subject, it faces a great number of support and opposition depending on human perception. It has various advantages ...

Embryonic stem cell is a crucial factor in the developmental process of a multicellular organism. Embryonic stem cells (ESCs) are derived at early stages during development and eventually give rise to all type of tissues and organs in an animal. The ES cell lines have three properties consisting of self-renewal, primary chimera formation and pluripotency [1]. Pluripotency, a key feature of ESCs, refers to the capacity of a cell to differentiate into several different types of tissues [2]. An array of cellular factors play important role in maintaining pluripotency and determining cell fate in the developmental pathway. Negative effects on these factors may ...

Abstract

Cumulative semantic interferenceThere is good evidence now that when picture of the object are presented, naming times become a little longer for each exemple from a given semantic category (e.g., when a naming several animals or vehicles) the effect has been referred to as cumulative semantic interference. In previous work, we have presented words and picture in groups of four (e.g. prim word, unrelated filler word, unrelated picture, target picture) naming related word prime slowed down the naming target picture. In the present experiment, we extended this work by presenting blocks of five sequences of four such stimuli (e.g. 20 stimuli in ...

Introduction

Bryophytes represent the oldest plants inhabiting the land, with some scientists putting its age to approximately 400 million years. Although a single plant is very small when viewed in isolation, their presence in forests is very conspicuous with some forests having a large mat cushioning trees trunks, rocks, and walls in the woodlands. Bryophytes comprise of three major taxonomic groups which are Bryophyta, Marchantiophyta, Anthocerotophyta. For this lab report, three species of Mosses, which is in the Bryophyta group and two species of Lichens will be used.
The behavior of mosses in relation to absorption of water and the antiseptic ...

- Most frighteningly, because many of these painkillers cause slow breathing and because teens have a tendency to mix painkillers, they can even cause teens to die.
- Of course the primary effect painkillers have on teens is to make pain subside.
- The lucid effect painkillers provide also encourages teens to use them recreationally.
- Over half of teens using painkillers do not actually need them, but only use them as a source to get high.
- Continuous use of painkillers to get high may be thought to be harmless by some but it is not.

IMPLICIT ASSOCIATION TEST FOR RACE

Abstract
The Implicit Association Test (IAT) measures human attitudes. Implicit attitudes are considered those judgments or actions of people that are automatic and the person has no idea what causes that judgment or action. The automatic action is a result of influences from societal beliefs. IAT is different from qualitative psychological tests for measuring attitudes because the measurement is of the cognitive processes of memory that cause a person to show a particular attitude automatically. IAT-Race was used to study racial stereotypes in an experiment to determine if the “Obama Effect” was observed. The participants were prompted to go to a web ...

Extraneous variables may have an influence on the dependent variable. In what ways do researchers attempt to control extraneous variables?

Extraneous variables are variables which have not been controlled while dependent variables are the probability of achieving success. Extraneous variables have influence to the outcome and researchers use some methodology to control them.One of the ways researchers use is making the extraneous variable constant where they try to ensure that there are no changes in the values taken by the extraneous variables during experiments through randomization. For example, when one is testing the effect of temperature on plant growth soil type and amount of water to be constant. These are extraneous variables that affect the experiment. This method of ...

Abstract
There have been increasing notions on matters regards to the essentiality of in-class experiment on the students’ performance. Historically the researchers have offered varying analogies on the respective entities in regarding the issue. The various historical claims made on the value of laboratory work in schools have been based on both perspectives and facts that various researchers have established. The commonly contradicting notion by various stakeholders in respective to the issue argue that the students are basically unaware of some of the essence experiments. They argue that some of the experiments by the students they have no ...

Abstract

The events of an accident that students watched in a YouTube clip were followed by some questions to these students. The question about how fast the cars were going before they smashed into each other resulted into higher estimates of speed than when the verb was replaced with hit. On conducting another test on the same participants a week later, the probability that the participants who received the verb smashed recalled seeing glass after the accident was higher than that of the participants who received the verb hit. These disparities in the answers are consistent with the view that the nature ...

Introduction

In the research on disaster management during a disastrous situation both natural and man-made disasters such as earthquakes, hurricane, tornadoes and terrorist attacks, I would suggest to use Descriptive Design. These kind of design provides answers to the questions of where, when, what, who and how. It provides information concerning the existing status of the happening and explains what exists with respect to the condition of the situation (Creswell & Creswell, 2007). It involves collecting data in order to test hypotheses or answer questions concerning the current status of the situation. It also involves conversion of data in numerical form so ...

Part A.

- What is the definition of Socialization and why is an understanding of socialization important in the examination of how social groups interact?
A. Socialization is referred to as the act of establishment through interaction on a socialist manner. Interacting with other people involves a simultaneous struggle to get the message across and at the same time, to understand what other individuals are saying (Ashforth and Mael, 1989). The importance of socialization in examining interaction between social groups provides us a clue of the common patterns in their social behavior, their differences and the conflicts that may arise due to those ...

Abstract

The aim of this study is to examine benefits of ultrasound over MRI as an imaging modality for assessing fetal brain. This study establishes that these two imaging modalities mainly play matching roles. Several differences exist in relation to the laws, abilities, technology and guidelines governing abortion. These differences have a significant effect on how pathologists use prenatal imaging in their treatment procedures. Based on the roles that each method plays and other predetermined factors, a person has to select the most suitable and applicable imaging modality. The benefits and confines of the two imaging modalities when establishing a fetal brain are ...

Snake oil peddlers, magicians, and charlatans have been with us since the dawn of humanity. As technology advances, the aforementioned hucksters tend to cloak their trade in the mystique of the novel and contemporary enlightenments. The belief in telekinetic activity and the idea of controlling things intrinsically with thoughts has grown in popularity as we have moved into a world where scientific advancement is providing a sound physical basis for these wonders. Promoters of ESP and psychokinesis would like people to believe that it is possible to un-tap the minds power to perform physical tasks without the exertion of physical activity. ...

Kale has the capability of growing in any climate zone (Vanderlinden). Some of the popular varieties of kale include the Red Russian, which has light purplish stalks, grayish-green leaves, and purplish veins. The Red Russian variety is the most delicious variety. The other variety is the Lacinato, which is also referred to as dinosaur kale, cavolo Nero or Toscano Kale (Rutherford-Fortunati). This variety is extremely hardy with the leaves getting very tough when ...

Magnetism is the ability of a material to exhibit attraction or repulsion of certain magnetic materials due to the presence of magnetic fields. Magnetism may be permanent or temporary depending on whether a material is a hard or soft magnetic material. Magnetism arises from the existence of small atom-like structures referred to as magnetic domains that, when aligned, cause the effect of magnetism to be pronounced in a magnetic material (Huebener, 135).
Magnetism depends on the alignment of domains and in the same direction. As such, increase in temperatures results in increased random movement of domains, and hence affecting their alignment. On ...

Experimental research

Experimental research is a quantitative study design used by investigators to establish a cause-effect relationship. This can be done through a true or quasi-environment, which are different as discussed in this write-up.

Similarities

Differences
Firstly, true experiments are used where it is possible to manipulate all the possible variables with a view to measuring the results, while quasi-experiments are applicable where the investigator is unable to control all the factors that are likely to cause the hypothesized effect (CSU, 2013). Moreover, true experiments require that the samples employed in the study be randomized in order to avert bias and confounding variables. This is ...

Abstract—In this experiment, a hand dynamometer was used to measure the grip strength of a subject. The forearm muscles were engaged in an activity, and the grip recorded. The electromyogram (EMG) activity was related to the grip strength by making a graph of the maximum grip strength against area under the EMG activity’s absolute integral during the contraction of muscle. Data was recorded from the dominant and non-dominant forearms of the subject and the electrical activity of each forearm compared to its diameter. Prolonged grip strength was also recordings and forearm EMG activity made to determine fatigue rate in both ...

1. Design of Experiment (DOE)
This technique uses experimentation to statistically determine what variables will improve the design or quality of a product. Design of experiments (DOE) is desirable when robust design or quality improvement is required. DOE helps to pin point the sensitive areas in designs that cause problems in production or yield.
2. Example of a DOE Case
DOE was used in the amplifier design process to investigate the sensitivity of this amplifier to process variation. It was necessary to find out the presence of elements in the amplifier design that could potentially affect the output ...

When a memory is created, it has to be stored, regardless of how briefly this would take place. Experts have established three forms of memory storage: first in the sensory stage, then in the short-term memory, and finally, in the long-term memory, even though the latter does not apply to all memories (Georg 2010). In the sensory memory, the person registers information and perception occurs at this stage. It takes minimal time in this memory. The sensory memory then encodes the information and categorizes them as either short or long-term memory.

Abstract

Knowledge on phase equilibrium behavior plays a central role in the prediction of the solubility of the components found in biodiesel. This aids in the separation process of the individual components. These components are normally referred to as volatile organic compounds. It is crucial to use models in the determination of these equilibriums since actual measurements are costly and lingering.
There are several types of biodiesels: methyl oleate, ethyl stearate, and methyl linolenate. UNIFAV procedure can be used in the determination of of an estimate of the infinite dilution activity of several volatile organic compounds in biodiesels. A mole ...

Project Description

Management Information Systems (MIS) is one of the new and growing research fields in terms of human factors. This development is based on the fact that systems used in MIS are man-made and they cannot attain their desired efficiency levels if the human factors are not utilized effectively in the system. Moreover, the technical area of the MIS system will not perform if the system’s human part is nonfunctional. This means that the “fit” that exist between the equipment, the user, and their environment should be taken into consideration. As such, MIS system should have the appropriate shape, ...

The organization/effects of the Civil Rights Movement and the Tuskegee syphilis experiment are two vital components of race relations that chiefly define how African-Americans were treated in the 1950s. These two events are evidence of the uniquely difficult sociopolitical status African-Americans had in the 1950s; the treatment of blacks by whites was negative to the point where African-Americans were actually experimented upon without significant consideration for research and medical ethics. Given the importance of civil rights, the way in which these initiatives are organized and used after the fact (in political narratives) must be examined, in order to prevent ...

Question 1

Descriptive research purposes to describe the characteristics of a given population or a phenomenon that is of interest to a researcher. It is also referred to as statistical research. Descriptive research is systematic, factual and accurate. In descriptive research, the researcher does not evaluate causal relationships between variables. Therefore, the internal validity requirement for this kind of research is low. Descriptive research relies on measures of central tendency and dispersion, frequency distribution and graphs. On the other hand, inferential research aims at making predictions about a given population from a sample that the researcher analysed. In inferential research, the researcher evaluates causal relationships and ...

Social science and impact in early marriages in higher education settings.

Higher learning institutions have for a long time been associated with early marriages. Most youths get engaged to early sexual relationships leading to unwanted pregnancies and sexual transmitted diseases. In an attempt to cope with the results, the youths get married with limited financial sources to support these marriages.
More interactive results with most of these students associate the contents of the syllabuses in these institutions to this behavior. The students think that social science is too exploitative on affairs and social settings and these makes the youths believe that marriage at early ages can work. The following is a ...

Children's Understanding of the Modal Expression of Speaker Certainty and Uncertainty and its Relation to the Development of a Representational Theory of Mind
In 1989 Chris Moore, David Furrow and their associates conducted a research regarding certainty differentiation and showed that by the age of 4 children become able to recognize and understand terms in sentences which reveals degrees of certainty. Some researchers showed that children begin to use these terms in everyday speech when they are 2-3 years old. However, this does not mean that they understand them. According to Green, the process of understanding comes during the concrete ...

According to Conover, Skloot, in her book, addresses the gigantic issues of medical experiments as to “who owns our bodies, the use and misuse of medical authority, the unhealed wounds of slavery” (qtd in Skloot 2). Skloot addresses story in the history of the United State’s medical field whose past is clouded by a dark history of human medical experimentations. The dark history in western medicine shows a record of horrifying events of medical experiment carried out on patients. Unfortunately, many of such experiments have been performed on children, impoverished people, and other marginalized vulnerable groups. As if that is ...
