BIO103 Environmental Biology – Effects of Alcohol on Human Coordination
Introduction:
Alcohol is known to produce many chronic abnormalities that are attributable to parietal lobe dysfunction. The self becomes aware of the body being a
distant object but it feels a strange attachment feeling (Miller et al, 1991). Considerable laboratory research indicates that different levels of alcohol
consumption contributes to overall behavioural and cognitive functions and therefore the reason for carrying out this study is to test the effects of
alcohol on human coordination. According to Allum et al (1998) Alcohol effects information received by brain receptors causing the working ones to
compensate for the defective information processed by ... Show more content on Helpwriting.net ...
Although this is the case, the investigation was poorly set out. Only one standard alcoholic drink was consumed which, as shown in the data, isn't
enough to lose coordination unless the subject had extremely low tolerance to alcohol. Subjects were not discriminated by age gender and body weight
which would have shown different results if these points were discriminated against and would have displayed a stronger correlation between the
effects of alcohol on human coordination. The sample was not large enough to show a strong enough correlation between alcohol and coordination in
the data therefore making the test inaccurate. Overall it seemed that as the subjects had more practice at the game, the better they became.
In a past investigation carried out by Patel et al (2010), three groups of adults were assessed at 0.00%, 0.06% and 0.10% blood alcohol concentration
to assess if alcohol affected body coordination. Subjects were asked to rate their drunkenness on a scale from 1 to 10 for each group. Results had
shown that their score had no effect on body movement coordination patterns but those who consumed a higher amount of alcohol experienced a more
significant effect on their coordination due to blood alcohol concentration. In this experiment, the groups showed a larger correlation between effects of
alcohol on human coordination and therefore more accurate

Essay about The Stroop Effect Experiment
METHODS Participants There were nine participants in this study, five in the first group and four in the second group. The first group included
Daina Berry, Justin Quintrell, Paige Govey, Natalie Campbell, and Jared Flannery, while the second group included Megan Powell, Kyle Sugonis,
Abigail Mrozek, and Vanessa Landgrave. These participants are undergraduate students from Dr. Kelling's 11:00AM Experimental Psychology course.
The students partook in the study in order to receive a passing grade for the class assignment. Equipment This experimental research was conducted in
a laboratory setting. The necessary equipment for each group included a stack of twenty squiggle cards, a stack of twenty word cards, and a stopwatch.

After the participant said the color, the flipper quickly positioned that card in one of two piles on the desk, thus revealing another card to the
participant. One pile held correct responses; the other pile contained incorrect responses. This routine continued until the last color was identified. At
that time, the timer stopped the stopwatch and announced the time. Each participant then recorded this data. This small procedure was then repeated
using the Word Cards. When the first participant had identified the colors of both the Squiggles Cards and the Word Cards, the flipper shuffled each
deck. The second participant was announced, and the cycle continued. This process was repeated until each participant had a turn with the cards.
This completed Trial One. Trial Two was conducted exactly the same way as Trial One: Squiggle Cards and then Word Cards. The second group. To
begin, the group members determined that students would exchange roles. When Megan Powell was the participant, Abigail flipped and Kyle timed.
When Abigail Mrozek was the participant, Megan flipped and Kyle timed. When Kyle Sugonis was the participant, Megan flipped and Vanessa timed.
Finally, when Vanessa Landgrave was the participant, Kyle flipped and Megan timed. Participant order was chosen by consensus. Then the repeatable
part of the procedure began. The first participant was determined. On the timer's command, the flipper pulled a Squiggle Card so that it was facing

Determination Of Biomass, Protein, Carbohydrate And Lipid
Determination of biomass, protein, carbohydrate and lipid For the estimation of dry biomass, 2 ml culture was removed on 10th day from each flask,
and absorbance measured at 750 nm spectrophotometrically (Shimadzu UV mini 1601, Japan) and converted to dry biomass using the regression
equation Dry biomass (mg ml–1) = Abs750+0.0378/0.0009 (R2 =0.995; P< 0.001) based on a standard curve constructed depending on Abs 750 vs
dry biomass. To determine dry biomass 10 ml microalgal culture with known Abs750 ranging from 0.1 to 0.5 were filtered through pre–combusted

Optimization of medium composition and culture conditions Experimental design Selection of significant variables by Plackett–Burman design The
screening of significant variables influencing biomass production of Chaetoceros muelleri was accomplished by Plackett–Burman experimental design
using the statistical software Design Expert (version 6.0.9, Stat–Ease Inc, Minneapolis, MN). Three nutritional parameters (nitrate, phosphate, and
silicate) and four physicochemical parameters (temperature, pH, salinity, and agitation speed) were screened, having each variable tested at two levels,
as minimum (–) and maximum (+). The minimum and maximum limits of the variables were nitrate (A):7.5–150 mg l–1 ; phosphate (B): 0.5–10 mg
l–1; silicate (C): 3–60 mg l–1; temperature (D): 20–30oC; pH (E): 6–9; salinity (F): 15–40 ppt and agitation speed (G): 100–200 rpm. For screening the
above variables, microalgal culture having absorbance of 0.2 at 750 nm was inoculated to a final concentration of 10% (v/v) to 100 ml medium in 250
ml conical flasks having varying composition as formulated by Plackett–Burman design. The design matrix, consisted of 11 variables with 12 runs (N),
with D1 to D4 as the dummy variables was used to evaluate the standard errors (SE) (Table 1) . The experimental cultures were incubated in triplicate
for 10 days in a shaker

Results of a Memory Study
The results of the experiment indicate that recall is more accurate and easier when a set of numbers are smaller chunks as opposed to larger chunks.
The mean recall of the control group was 8.81 compared to a mean of 4.69 in the experimental group. These findings are consistent with David W.
Fendrich and Raina Arengo's (2003) findings which indicate that the length of a string of numbers does affect the ability to recall. Although the
participants found it significantly harder to remember the numbers in larger chunks, the results do indicate that it is difficult for participants to recall
chunks when the number of chunks surpass the "Magical Number Seven" plus or minus two based on Miller's (1956) findings. This supports the
hypothesis of this experiment and confirms the findings of the original experiment. However, the results may have occurred because of the
overwhelming amount of numbers in the experimental group as opposed to the minor amount of numbers in the control. This experiment was
conducted under laboratory conditions which contains many values and limitations. Conducting a laboratory experiment allows the experimenter to
freely manipulate the independent variable which demonstrates cause and effect relationships. Lab experiments allow for an increased control of
extraneous variables and accurate measurement of findings. The standardized procedures also allow for replication to occur. However, total control of
variable is impossible. The only participant

Summary Of Princess Alice Is Watching You
Princess Alice is Watching You Summary In the article titled "Princess Alice is watching you: Children belief in an invisible person inhibits
cheating by Jared Piazza, Jesse Bering, and Gordon Ingram the experimenters describe an experiment to test the prediction that children would be
less likely to cheat if there is an invisible person watching them. Within this experiment there were 2 children groups, one group was of 39
children between the ages of five and six. While the other group consisted of 29 children with the age of eight or nine. One of the six year olds
was omitted from the study due to the fact he could not comprehend the task at hand. Within this experiment the children were asked to complete a
task and were told either a) they were in the presence of a watchful invisible person, b) they were being observed by a real adult or c) they were
unsupervised. This was a three x two factorial, with the three meaning condition while the two meaning age group. The experimenters introduced
both Princess Alice (invisible person) and the real observer as friendly. The game consisted of children having to throw a Velcro ball at a target and
get it to stick and if they completed a take they received a prize. But the task was nearly impossible due to three rules the children had to follow.
These rules were placed to cause the children to cheat. The procedure they followed for the children was: First the children arrived with their parents

Testing And Experimentation Isn 't A Buzz Term
Introduction Testing and experimentation isn't a buzz term, a lot of astute marketing and designs are incorporating it to step–up the conversion rate and
also gain insights into customer's behavior [3]. The advantage the web has over other channels is the capability to test and fail at a reduced cost
[7]. A test is defined as a procedure for critical evaluation carried out to achieve good, measurable results in a short time frame [10]. Most people
think of experiments as restricted to chemistry lab or by cross breeding plants in the name of biology, but marketing experiment has been around
for a long time, from testing concept stores in various geographies before the product is launched to showing different television curriculum in a
particular state at different time for different audience [10]. In order for the business to scale through magnificent height, a testing program should
be adopted for every business regardless of its size [7]. The following are the benefits of experimenting and testing for every organization: Guess
work is eliminated; you no longer have to presume what will work on the website [7]. The website goals can be easily identified and measured [7].
The web analyst is less concerned about analytics for reporting or building multivariate or regression platforms, every testing tool comes with various
analytics reports [7]. Experimenting can be conducted for free using tools such as Google website optimizer [7]. The customers can participate in

The Effect Of Scientific Information On The Explanation Of...
Previous research has shown the effect of neuroscience information in the explanation of psychological phenomena. This study aimed to replicate such
findings and what effects other superfluous scientific information had on the perceived quality of explanations. 340 university students were instructed
to read and evaluate a brief description on a psychological phenomenon followed by explanation of varying quality and superfluous information of
various types. Good explanations were rated with a significantly higher perceived quality of explanation in comparison to bad explanations.
Explanations containing neuroscience information showed significantly higher ratings of quality in comparison to explanations containing hard science
and social science information. There were no significant differences between bad explanations containing neuroscience and social science information
or between conditions which contained social science and hard science information. As our findings demonstrate the seductive effect of neuroscience, it
can be concluded that there is something about the brain in relation to the theory of mind that makes it the most alluring explanation for psychological
phenomena.
Public interest in psychological phenomena is evidenced in news articles and other forms of social media reporting neuroscientific findings and hence
implications on how people evaluate information and make decisions has been an ongoing area of research. Previous research has shown

The Destructive Nature of Man Depicted in Keyes' Flowers...
Imagine how you would feel if you were always being treated as though you were not human, or if people acted as though they created you. Well this
is how you would feel if you were the subject of a science experiment. Science experiments should not be performed on humans or animals because of
the unknown outcome. Flowers for Algernon by Daniel Keyes shows a destructive nature of man through stereotypes, absence of family, and the
various IQ levels needed to mature. Scientific experimentation shows a destructive nature of man through stereotypes. Stereotypes are cruel and
heartless. "He makes the same mistakes as the others when they look at a feeble–minded person and laugh because they don't understand there are

He wants to see them but is unable to find them at this point. This is a destructive nature of man because of the science experiment. After the surgery
Charlie will expect his family to love him again because he will be smarter than he is now. Charlie will basically have a false hope of his family
after the surgery. When there is an absence of family there is a destructive nature of man, "Lack of family bonds can lead to forever seeking that
something that is missing." (D, Kathy) When there is a lack of family that person will always be searching for the missing piece in their life. The
person searching will ultimately end up disappointed. Therefore, absence of family leads to a destructive nature of man. A destructive nature of man
is shown through IQ versus maturity. Scientific experimentation leads to a destructive nature of man. "Their is a lot of werk to catch up. They dint

have been given a false sense of intelligence. Later on Charlie becomes more mature which ultimately means he is more intelligent. "But I still have

Evoking Freedom Study
The Effects of "Evoking Freedom" Technique on Compliance Social influence and the power of social situations have always been central topics of
inquiry for psychologists due to their impact on our everyday lives. Social influence refers to the ways in which people alter their attitudes, emotions,
and behaviors of others. Every day, we encounter countless attempts by other people to influence us. Likewise, we try to influence others. Compliance
is a kind of social influence in which an individual modifies his or her behavior in response to an appeal made by another person. Many studies have
investigated effective means of increasing compliance rates.

Also, if the cost of the request plays an important role as predicted in determining the compliance rate, we should see a higher compliance rate in a
low–stakes request in the presence of the "evoking freedom" technique than in a high–stakes request in the presence of the "evoking freedom"
technique, and a higher compliance in a low–stakes request in the absence of the "evoking freedom" technique than in a high–stakes request in the
absence of the "evoking freedom" technique. If we had seen these effects, it would have also meant that we support the idea that when one is given
the freedom to accept or refuse a request, he or she will be more likely to comply even with a request that is costlier for that

Essay on miss
Q 1. In this practical exercise you will be using biuret reagent. Why is biuret reagent used in this practical?
The biuret reagent is used to assess the concentration of the protein because peptide bonds occur with the same frequency per amino acid in the peptide.
The intensity of the colour, and therefore the absorption, is directly proportional to the protein concentration.
Q 2. What is the experimental reason for constructing a standard curve?
Multiple samples with known properties can be measured and graphed, which then enables the same properties to be determined for the unknown
samples, in this case the concentration, by interpolating the graph which depicts the relationship between the absorbance and concentration. ... Show

(2 and 4 sentences)
One way in which the experimental procedure could be modified is diluting the sample. This involves decreasing the volume of BSA Protein solution
and increasing the buffer volume by the same amount. As a result the absorbance would be lower and fit on the graph. Another way may be to extend
the curve by increasing the concentration of the BSA Protein solution which would provide a greater range.
Q 7. Do your results support your hypothesis regarding these tissue samples? (2–3 sentences)
The hypothesis regarding the tissue samples was supported. The absorbance of the sun raised silverbeet plant was found to be 0.801, which was greater
than the shaded silverbeet plant with an absorbance of 0.369.
Q 8. One possible reason for the results not supporting your experimental hypothesis is experimental error. List three examples of possible sources of
error that may have occurred in your work in this practical class. (2–3 sentences)
A possible error may be adding inaccurate amounts of buffer between samples, causing them to dilute either excessively or insufficiently, resulting in an
inaccurate standard curve. Another error could be leaving the sample solutions for over 25 minutes, which could cause the protein to start degrading.
Not zeroing the spectrophotometer or cleaning the tube properly can affect the absorbance value.
Q 9. Even if your results do support the experimental hypothesis, give three major possible

The Spatial Relations Test has also been used in the study of Piaget's concepts in their application to art education.
Studies performed by Morra (2005) in Italy determined the differences in drawing flexibility in four– to nine–year–olds and the main causes for the

the factors that affect their drawing abilities. In the first experiment, 225 children in an urban environment in northern Italy from the ages of five to

The groups were divided by the order the drawings were instructed and the presence of a visual aid. The children were tested in very similar conditions
as in the first experiment, with variation in the drawing requirements and scoring. They were individually instructed to draw a human standing, one
walking, and one running with or without the assistance of three photographs displaying a person doing the related action. An assessment with eleven
distinguishing criteria and same two tests, the digit span and Mr. Cucumber, followed the completion of the drawing activity. Morra then performed a
third experiment to conclude this study on drawing development.
In the third experiment, 240 children in southern Italy from the ages of four to eight were assessed, this time without the assistance of a visual aid
during the drawing exercise. These children were also from an urban environment, but associated with a notably lesser economic status than the
previously included subjects. The children were, like the others, tested in a quiet, private environment with no time limit. First, they were instructed to
draw the image of a human being. Days later, they returned and were shown four pictures of different kangaroos for a total of fifteen seconds each.
They were promptly instructed to draw a picture of a kangaroo without a photograph present. Their drawings were

The Design And Analysis Of Computer Experiments
Introduction
According to the case study, the design and analysis of computer experiments (DACE) were applied as a tool to identify the risks associated with
laser welding in an electronic welding process for developing the substrate product development effort. This process, DACE, used the computer
simulations to easily predict the stresses and warp of the sample with varying factor levels. The main advantage here is instead of making eight
different samples, the whole work was finishing with a computer, and it saves a lot of time and money.

So, the team uses only 25–2 fractional factorial designs through computer simulations.
However, the team uses finite element analysis software along with DOE to predict two responses from each run such as the stress and the
deformation. In the case study, we observe the images that show the stress and deformation due to a temperature change. The high stress and
deformation areas are shown by the red color. The low stress and deformation areas are indicated by the dark blue color. At last the deformation of a
single layer was imported into MATLAB (a matrix computing environment) to calculate the radius of curvature or warp.
The immediate step in this sequential experimentation was enhancing the factorial experiment with a center point and star–points i.e. a central
composite design (CCD), fully explores the extremes of the factor levels. It goes beyond the +1/–1 levels to get a better understanding of the effects
the factors on the results. The CCD consisted of a center point and six–star points. The star points represent the +/– 2 alpha levels of the factors. Here
the dots are connected to one another through the center; the resulting shape is a star. There are six dots because there are two extreme cases for each
important factor. This analysis helps to provide a better understanding of the effects on results such

Conformity Essay
According to Leon Mann, conformity means 'yielding to group pressures'. Everyone is a member of one group or another and everyone expects
members of these groups to behave in certain ways. If you are a member of an identifiable group you are expected to behave appropriately to it. If you
don't confirm and behave appropriately you are likely to be rejected by the group.
Like stereotypes, conforming and expecting others to conform maintains cognitive balance.
There are several kinds of conformity. Many studies of conformity took place in the 1950's which led Kelman to distinguish between compliance,
internalisation and identification. Compliance is the type of conformity where the subject goes along with the group view, but privately ... Show more

During the group sessions it became apparent that the subjects reports strarted to converge much nearer to an average of what their individual reports
had been. If a subject who had said that the light didn't move very far when tested individually said 'I think it is moving 2 inches to the left' then
another who had reported movement of 4 inches, when tested individually, might say 'I think it may have been 3 inches'.
As the number of reported movements continued the more the members of the group conformed to each others reports. This spot of light was in fact
stationary so whatever reports were made was the consequence of the subject imagining they saw something happen. So they were not certain about the
movement they observed and so would not feel confident about insisting that their observations were wholly correct. When they heard other reported
judgements they may have decided to go along with them.
The problem with this study, for understanding of conformity, as one aspect of social psychology is that it is a total artifical experimental situation–
there isn't even a right answer. Requested reports of imaginary movements of a stationary spot of light in a darkened room when alone, or with two
others, hardly reflects situations we come accross in our every day

The Effects Of False Memory On Word Association
False Memory
Cammie Wires
George Mason University
False Memory
Introduction
Multiple studies have been conducted that investigate false memory in humans focusing on word recall, processing and retention interval, and
auditory imaging. Roediger and McDermott (1995) suggest that individuals who participated in their study are more likely to recall the critical
words and lures if the list of words presented were closely associated to them. Critical lures are the tendency to recall words that are associated with
presented information (Kreiner, Price, Gross, Appleby, 2004). Roediger and McDermott (1995) also suggest that the same individuals will be more
familiar with the critical lures compared to the words actually presented (Roediger, McDermott 1995), while other studies suggest similar conclusions.
This paper will discuss the effect of false memory with word association, the ability to retain the words, and auditory learning and testing with research
done by Roediger, McDermott, Gallo, Pilotti, Jacoby, and Thapar.
Literature Review In Thapar and McDermott's (2001) study, they wanted to measure how false recall and recognition change does over a period of
time. They also studied the effects of the level of processing and retention intervals on false recall (Experiment 1) and false recognition (Experiment
2) of critical lures. Thapar and McDermott's (2001) hypothesis states there will be an increase in false recall compared to actual recall. To test this

The purpose of this experiment was to test the validity of using facial electromyography (EMG) as a physiological measure of the valence of radio
listeners' emotional responses to advertisements and to explore the effects of message valence and listener arousal on attention and memory. This study

real–time, physiological measure of the valence of radio listeners' emotional responses to messages. This study also addresses three questions in
understanding the relationship between emotional media messages and audience member's response to those messages. The researchers submitted four

The final hypothesis predicted that if the positive and negative advertisements were perceived as equally arousing, then the positive radio
advertisements would be more memorable than the negative advertisements. Results demonstrated the validity of using facial EMG to assess the
valence of emotional response to media messages. Heart rate data suggest that negative messages receive more attention than positive ones. It also
shows that how arousing a message is appears to be a better predictor of memory than message valence. The main effect for Valence on zygomatic
muscle activity and corrugator muscle activity was significant. Corrugator muscle activity increases and then levels off over the course of negative
messages but is significantly lower and slightly decreases over the course of positive messages. Heart rate was significantly slower during negative
messages compared with positive messages. The results indicate that valence predicts facial EMG, whereas arousal predicts

Using Reading Materials And A Free Recall Test
College students typically have poor study habits between procrastinating to the night before the big exam and then only rereading over the material.
Most of these habits stem from high school were most learning is done inside the classroom with a teacher and little time is needed to spend at home to
review. In contrast, college has a largely reduced amount of learning in the classroom setting, and instead requires a lot of studying to be done by the
student independently. Study methods such as study and retesting has been proven to be the most beneficial when it comes to retaining the information
in memory and further more improving comprehension. An experiment completed by Roediger and Karpicke (2006) examined the testing effect using
reading materials and a free–recall test to replicated a conditioned educational setting. They further explored the learning benefits of retesting. They
hypothesized that the more study opportunities allowed would increase higher performance ratings on immediate retention tests. However, taking
recall tests after studying would increase retention on delayed testing unlike restudying only. They conducted a total of two experiments. The first
experiment had a total of 120 undergraduate participants and used a 2 x 3 mixed factorial design. The first independent variable was the learning
conditions with two levels, restudy and testing, within subjects; the second independent variable was the delay of final tests, 5 minutes, 2 days, and 1
week,

performance of milling as a good–quality milled surface significantly improves fatigue strength, corrosion resistance, or creep life. The surface
generated during milling is affected by different factors such as vibration, spindle run–out, temperature, tool geometry, feed, cross–feed, tool path and
other parameters. During finish milling, the depth of cut is small. The most important interactions, that effect surface roughness of machined surfaces,
are between the cutting feed and depth of cut, and between cutting feed and spindle speed. Surface Roughness is affected negatively if the applied
force is increased. Surface roughness at the same feed rate becomes higher when a small nose radius is used. Technological parameter range plays a
very important role on surface roughness. There is a need of a tool that should allow the evaluation of the surface roughness before the machining of the
part and which, at the same time, can easily be used in the production–floor environment contributing to the minimization of

Quality Of The Software Engineering
This paper mainly speaks about the study of quality of the Software engineering papers and is related to the topic "Quality" in our present syllabus.
Quality can be expressed in different way or aspects by different set of people. In this paper, they define about human–centric software engineering
experiments to be studies of software engineering methods, techniques, and procedures that depend on human expertise. The trial configuration and
factual strategies to programming specialists undertaking empirical studies. Nonetheless, performing a similar study based on papers from
International Conference on Software Engineering (ICSE) and Empirical Software Engineering and Measurement (ESEM) may be a fascinating point

And they have restricted themselves to assessing the quality of journal papers and there were 14 papers appearing in the International Conference of
Software Engineering (ICSE) in a specific time period. This has expanded the homogeneity of our arrangement of papers to the detriment of
decreasing the consensus of our decisions. This paper is about to explore whether are there any increase in the quality of the papers in the field of
software engineering which discovers the quality of the software engineering papers and are there any increase in the quality of human–centric
experimental and quasi–experimental journal papers over the time period (1993–2010). And here the quality of software engineering papers are mainly
based on three points. They are: a) The use of random allocation to experimental conditions, b) The use of single–blind versus double blind procedures,
c) How dropouts were analyzed.
Summary of the Paper: The quality of the software engineering papers was calculated by answering 10 questions where nine questions are about the
human–centric experiment/quasi–experiment and the last question is about the overall subjective assessment of the quality of the study. The scoring for
the questionnaire vary from 0–3 for every question. Below are the list of the nine questions that are analyzed and marked for the quality of the paper.

Summary of the Research
In their article, "Differences in Mouse Maternal Care Behavior – Is There a Genetic Impact of the Glucocorticoid Receptor," Chourbaji et al. (2011)
report a 2*2 factorial research design to determine the effect of mutations in Glucocorticoid Receptor (GR) on the maternal behaviors in two different
strains of inbred mice. The experiment was conducted in three main stages. The first stage was the production of GR heterozygous mice of both lab
strains under study. The next step was the controlled mating and delivery of the pups for knowing the effect of this mutation. The third step was the
observation of the maternal behavior in two strains. No significant differences in the behaviors of two strains were observed and ... Show more content
The soundness of theoretical reasoning
Chourbaji et al. (2011) described their hypothesis clearly in the introduction. They first justified the possible role of GR abnormalities in the
postpartum depression by describing the effect of this receptor in other stressful stimuli. They next described the differences in the emotional responses
of different strains that were used in this study and the reason for their use. They then described their hypothesis as the "emergence of a depression–like
behavioral profile in GR heterozygous animals, specifically an increase in maternal neglect and/or a reduction of caring behavior" (Chourbaji et al.,
2011). Overall, the research is based on sound theoretical reasoning.
The appropriateness of the experimental design
The experimental design lacks some significant factors that could have resulted in the prominent observation of the emotional changes in the maternal
behavior of mice. While it has been confirmed that home–cage observations can be the appropriate ways of knowing the physical or emotional
reactivity in mice, there are other ways to analyze the emotional response in mice. Some of these observational strategies also used invasive stimuli but
have been used to confirm the respective emotional responses under study.
The soundness of mathematics and/or statistical tests The use of General Linear Models (GLM) has not been justified in the paper. Additionally,
two–way ANOVA for strain and GR genotype has been

The Experimental Design Proposed By Taguchi Method
IntroductionThe Taguchi method involves reducing the variation in a process through robust design of experiments. The overall objective of the
method is to produce high quality product at low cost to the manufacturer. The Taguchi method was developed by Dr. Genichi Taguchi of Japan who
maintained that variation. Taguchi developed a method for designing experiments to investigate how different parameters affect the mean and variance
of a process performance characteristic that defines how well the process is functioning. The experimental design proposed by Taguchi involves using
orthogonal arrays to organize the parameters affecting the process and the levels at which they should be varies. Instead of having to test all possible
combinations like the factorial design, the Taguchi method tests pairs of combinations. This allows for the collection of the necessary data to
determine which factors most affect product quality with a minimum amount of experimentation, thus saving time and resources. The Taguchi method
is best used when there are an intermediate number of variables (3 to 50), few interactions between variables, and when only a few variables contribute
significantly. 4.1.2 Taguchi's Philosophy Taguchi's comprehensive system of quality engineering is one of the great engineering achievements of the
20th century. His methods focus on the effective application of engineering strategies rather than advanced statistical techniques. It includes both

One experiment was done by Sissy Rodriguez where she took 4 brands of paper towels and tested how absorbent each brand was. Her findings were the
generic brand absorbed more than the leading brands (Rodriguez, 2013). Another study was done by Amber Sainz. Her experiment was on how
absorbent three major brands of paper towel were. Her findings were out of three major brands (Brawny, Bounty and Scott) Scott absorbed the most
(Sainz, A. 2012).
Experimental Procedure * Purchase three rolls of different brands of paper towels. * Get a Notebook or piece of paper for data recordings. * Record
the three brands of paper towels on you data sheet. * Cut equal pieces from each brand. All three sheets must be exactly the same size. * Fill a
medicine or eye dropper with water. * Place paper towel over clear glass bowl with rubber band holding it in place. * Now squeeze one drop of water at
a time onto the paper towel. * Count the number of drops the paper towel would absorb before starting to drip into the clear glass bowl. * Record
your results. * Repeat with the other two brands.

going to give up this opportunity to bring science into their relationship.
In the lab where they begin to work on Georgiana is where we are introduced to the idea that there is a polarity between the spiritual and earthly
sides of Aylmer and Aminadab. Aminadab is " a man of low stature, but bulky frame, with shaggy hair hanging about his visage. This personage had

A QUANTITATIVE STUDY TO ASSESS THE INFLUENCE OF CONTEXT AND PERCEPTUAL CUES ON MEMORY RECALL.
Abstract The influence of context and perceptual clues on memory recall.
The influence of context on memory recall was examined in an experiment based on Godden and Baddeley's (1975) Context Dependent Memory study.
Previous research suggests that memory recall is improved when learning and recall occur in the same environment. The current experiment examined
the importance of context and perceptual clues in memory recall by manipulating the learning and recall environments for a memory task using a list
of 30 random words tested on three groups of participants: each group learnt a list of words in one environment and recalled them in ... Show more
The results can then be analysed and compared in line with Godden and Baddeley's findings.
5. Briefly explain the rationale for your research
This study will attempt to replicate the findings of Godden and Baddeley (1975) by examining the importance of context in learning and recall. In
addition, we will examine whether lack of perceptual cues in the environment affects recall.
Method Between–participants experiment 75 adult participants (15 for each project member) – 35 males – 40 females
Independent variable – Context – Condition 1 – learning and recall environment are the same – Condition 2 – learning and recall environment are
different – Condition 3 – learning and recall environment are the same, but participants eyes are closed for recall
Dependent variable – Number of words correctly recalled
The 75 participants were randomly allocated to three groups. Condition 1 – 25 participants were given a printed grid of 30 random words and given 2
minutes to memorise them. Participants were seated at a table/desk in a quiet room. After learning there is then a 2 minute pause after which
participants were given a further 2 minutes in which to recall the words. Condition 2 – 25 participants are given a printed grid of

The Sexual Function Of Laboratory Animals
Abstract
Castration in males may be the result of disease or injury. It is expected that after a castration procedure, the males will lose sexual function. In this
experiment there were seventeen male rats randomly distributed into three groups; sham group (N = 5), castrated and oil group (N = 4) and castrated
and testosterone group (N = 7). The control group received a sham operation and bi–daily injections of oil to show that it was not a surgical procedure
or bi–daily injections that caused the lowered production of testosterone. As expected sexual function was able to be restored in the castrated males by
giving bi–daily supplementation of testosterone hormone at the same rate that testicles would normally produce this hormone. The castrated males that
did not receive the testosterone injections but had received the bi–daily injections of oil, did not have successful restoration of their sexual function.
Studying sexual function in laboratory animals is important to be able to develop ways to supplement hormones in humans and to restore sexual
function in those who have suffered an injury or disease that resulted in a castration procedure. Introduction
Sexual function is dependent on the testosterone levels produced by the interstitial cells of the testicle. The role of testosterone deficiency in sexual
function can be directly linked to diseases of reproductive organs, injury, certain medications and aging factors. Males and females face this problem

Factorial research designs are experiments that involve factorial combinations of independent variables. Factorial combinations involve pairing each
level of one independent variable with each level of a second independent variable. Factorial combinations make it possible to determine the effect of
each independent variable alone (main effect) and the effect of the independent variables in combination (interaction effect). The simplest possible
experiment involves one independent variable manipulated at two levels. Similarly, the simplest possible factorial design involves two independent
variables, each with two levels. Factorial designs are identified by specifying the number of levels of each of the independent variables in the ... Show

They were supplied with information about their partner so that they could get a sense of his personal characteristics. In the identity–threat condition,
their partner held sexist views. For instance, they would strongly agree with statements such as "I could not work for a female boss because women
can be overly emotional and sensitive". In the identity–safety condition, the partner was presented as nonsexist and strongly disagreed with sexist
statements. The second independent variable in their 2 x 3 design was word type with three levels: 1) social–identity threatening; 2) illness threatening;
and 3) nonthreatening. This variable was manipulated using a repeated measures design; thus, all participants were tested with all three–word types in
a completely counterbalanced order. The social–identity threatening words were sexist in content, such as hooters and ho. The illness–threatening
words (mono, Alzheimer's, cancer) were included as a control condition to determine whether women in the identity–threat condition would pay

The Relationship Between Body Image And The Media
In comparison to the time span of history, the media is a relatively new presence in the world. Despite its rather contemporary status, the media is a
wide–spread entity in modern society. From television to the internet, and from social media to online news sources, almost every modern
American has access to the media in some way. Media has affected the way of life in many ways, including the way people view themselves. Body
image and the media have formed a relationship, and this relationship effects many people. It becomes particularly important to focus on this
relationship, especially when it comes to how it is changing the way people feel about themselves. Several studies have been done over this topic,
and there is a multitude of data that analyzes the relationship between body image and the media. In one study, researchers wanted to know whether or
not they could lessen the effects of the media on body image. Their main hypothesis was that if the women were not given psychoeducational
materials that were designed to make them disregard the importance of imitating women in the media, their personal body image would be negatively
impacted by images of beautiful women in the media (Yamamiya, Cash, Melnyk, Posavac & Posavac, 2004). The sample that was tested consisted of
123 white female students at Old Dominion University who volunteered to earn extra credit in their psychology classes. The participants were divided

7. When was the germ theory of disease proposed, and on what basis?
The germ theory was proposed by Robert Koch and Louis Pasteur in the 1870s, on the basis that microorganisms were the cause of many diseases.
PART III
1. Why was it useful to be able to verify the source of the water?
Verifying the source of water was the only way to prevent its spread. Since it is an epidemic, it affects many people at the same time, and it is very
important to stop the spreading into more communities to prevent further death and the expansion of the disease. Verification allowed companies using
that source to change where they obtained their water, and allowed water treatment to take place.
2. Why would a neighborhood served by two different water companies be more useful for testing Snow's hypothesis than two neighborhoods each with
their own source?
A reviewer in the London Medical Gazette suggested that Snow find people living side by side with lifestyles similar in all aspects except of their
water source. He made this suggestion because this would ensure that the neighbors breathe the same air and resemble each other more in variables
other than the water source. This would guarantee that the water is the source, and not other factors that is causing the cholera.
3. Epidemiologists often draw causal webs to illustrate the

In this way the researcher should review and build upon the work already done by others, but in cases where hypotheses have not yet been
formulated, his task is to review the available material for deriving the relevant hypotheses from it. Besides, the bibliographical survey of studies,
already made in one's area of interest may as well as made by the researcher for precisely formulating the problem. He should also make an attempt to
apply concepts and theories developed in different research contexts to the area in which he is himself working. Sometimes the works of creative
writers also provide a fertile ground for hypothesis formulation and as such may be looked into by the researcher.
(b) Experience survey
This means the survey of people who have had practical experience with the problem to be studied. The object of such a survey is to obtain insight
into the relationships between variables and new ideas relating to the research problem. For such a survey people who are competent and can contribute
new ideas may be carefully selected as respondents to ensure a representation of different types of experience. The respondents so selected may then be
interviewed by the investigator. The researcher must prepare an interview schedule for the systematic questioning of informants. But the interview must
ensure flexibility in the sense that the respondents should be allowed to raise issues and questions

Accordingly, Accuracy is also a continuous variable that can be measured by the number of word errors per minute. To operationalize health symptoms,
a questionnaire was administered to measure how many work–related health symptoms they had experienced since the last assessment. Extraneous
variables are important to control because they provide another explanation for the dependent variable changing that is not due to the independent
variable. Extraneous variables take two forms; Systematic Error and Random Error (Ghilani, 2010). In the present trial, a number of systematic errors
have been identified. Since all the independent variables are manipulated between groups they yield their own unique set of extraneous variables. The
obvious problem with between groups design is that they are tested between groups. Two groups of people differ in various things and it is difficult to
control both relevant and irrelevant factors. Random assignment has been used to control this confound; however this does not prevent other
systematic errors that comes with individual differences. This could possibly be resolved by using a repeated measures design, which consequently
eliminates the problem of group differences arising from individual differences (Christensen et al., 2014). Pre–existing skills of the workers may have
an impact on the result that may be difficult to control. Each worker may have different levels of expertise that contributes to the

Outline Of Experimental Design Procedure
OUTLINE OF EXPERIMENTAL DESIGN PROCEDURE
Experiments are carried out by researchers or engineers in all fields of study to compare the effects of several conditions or to discover something new.
If an experiment is to be performed most efficiently, then a scientific approach to planning it must be considered. The statisticaldesign of experiments is
the process of planning experiments so that appropriate data will be collected, the minimum number of experiments will be performed to acquire the
necessary technical information, and suitable statistical methods will be used to analyze the collected data. The statistical approach to experimental
design is necessary if we wish to draw meaningful conclusions from the data. Thus, there are two aspects to any experimental design: the design of
the experiment and the statistical analysis of the collected data. They are closely related, since the method of statistical analysis d depends on the
design employed. An outline of the recommended procedure for an experimental design is shown in Figure 3.1 and briefly explained below. Figure :

1.3Brief Description
Experimental methods have been dominantly used in physiology education for over a century(Cronbach 1957), which was slowly being adopted with
the inception of scientific studies, medical studies and other study areas in the light of which the research was modelled on established paradigms for
the field of their respective studies. This relied on experiments to derive equations and laws, to come up with thesis and principles. Thus, experimental
approach has been influenced in information technology over the last 3 decades by shifting its focus from conventional survey–based testing of a
proposed theoretical model to experimentation method.
2.Research Method
Research "In which an experimenter having complete mastery can schedule treatments and measurements for optional statistical efficiency, with

complexity of design emerging only from that goal of efficiency" (Campbell & Stanley 1963, p. 1) relates to experiments.

Experimental research methods are broadly classified into three areas
True Experimental Designs.
Quasi – Experimental Designs.
Non – Experimental or Correlational Design.

The women in the intervention and control groups were between the ages of 21 and 53 years and had a child within the last 18 years, while the
pre–pregnancy group consisted of "younger women who did not have children" (Petrofsky et al., p. 42). The intervention group participated in the diet
and exercise program, while the control group participated in all measurements, and the pre–pregnancy group only participated in the initial
measurements. The intervention included a diet and exercise program that was specifically designed to allow for weight loss over the 2 month
period of the study and the exercise program consisted of a specifically designed program to focus on areas of the body that are affected during
pregnancy. The primary focus was on increasing muscle mass and increasing overall strength. The exercise program was clearly outlined and
consisted of 30 minute exercise periods, which would increase each week, and was taken from a program of videos consisting of a combination of
core training and aerobic and strength exercise. In addition, the workout schedule is clearly identified in Table–2 on p. 43 of the Petrofsky study for the
