Summary: Dopamine is a neurotransmitter that activates different dopamine receptors throughout the central nervous system. As mostly invertebrates have been studied in the past, the researchers wanted to focus on vertebrates in this study in order to determine the evolutionary patterns of these receptors. Five dopamine receptor genes were studied in five different mammals, and it was discovered that genes that are expressed more broadly have slower evolutionary rates than genes that are…

To conclude my hypothesis was completely wrong and the fastest pipe was the small plastic pipe, which I predicted would be the slowest pipe. The average time the plastic pipe took to roll down the ramp was 0.86 seconds. The time was 0.01 seconds faster than the pipe that finished second, which was the steel pipe. The small plastic pipe had the smallest inertia, which was 0.000003 and finished first. Also the small plastic pipe had the smallest rotational and kinetic energy compared to the rest…

Copper-alloy miniature votive dagger. The pommel is uneven and spherical with a ridge at the top. The pommel narrows into the slightly curved grip. The guard is a square shape with two parallel grooves on each side. The blade narrows into a dulled point. There is a round hole three-quarters of the way up the blade. The back is chipped on the left edge of the blade near the point (as seen in figure 1) and has furrows on the blade below the hole. The front has scratches on the blade above both…

Review of article #1 This article is an un-randomized control trial to explore “the impact of mindfulness training for nursing staff on their levels of mindfulness, compassion satisfaction, burnout, and stress” (Honore, Pierce. Eure & Woodbridge, 2014, p.198). This study also gave a consideration to the impact of mindfulness on patient satisfaction. From the above level of evidence scale, this is a level III of the hierarchy. Validity. In this pilot study, a volunteered nursing unit,…

This study aimed to investigate the relationship between schizotypal personality and social cognitive functioning, in particular empathy and ToM. It was hypothesised that higher schizotypy would be associated with lower empathy and further, that negative schizotypal traits would have a higher association with lower empathy than positive schizotypal traits. Results from this study support the hypothesis as schizotypy was found to be negatively correlated with empathy, such that higher scores on…

The case-control design also has inherent limitations. One notable weakness is that it is essentially cross-sectional. Longitudinal studies collect data on alcohol use at baseline and follow study participants over time to determine if they develop AD. Because high levels of alcohol use are associated with greater mortality, drinkers may be more likely than nondrinkers to die before developing AD, so a protective association between alcohol use and AD may simply reflect selective mortality.…

In general, the experiment succeeded in demonstrating free-fall by dropping a tennis ball. Distance and time were documented to calculate velocity and acceleration, the quantities involved in linear kinematics. Graph 1 (distance vs. time) suggests a commonsensical relation - longer distance yields longer time. The only exception is at 1.0 m, where its time value (0.42 s) is less than that of a shorter distance (0.5s for 0.5 m distance). Average time was used to construct the graph, and there…

To do this experiment you will need two subjects that have different arm lengths. In this experiment Subject 1 had an arm length of .81 meters and Subject 2 had an arm length of .77 meters. It is crucial that the subjects have different arm lengths because if they don’t your results will be invalid. The first step in this experiment is to set up the camera using the tripod and insert an SD card. Next, position the camera perpendicular to the sagittal plane along the x-axis in regards to the…

Laboratory Exercise 1: Anatomy Lab Report Scientist: Eryka Ocasio Ramos Lab Title: Scientific Method and Measurements I. Problem: Is there a correlation between the length of the upper and lower limbs and the height of an individual? II. Hypothesis: The length of a person’s upper limb is equal to 0.4 (40%) of the height of the person. III. Variables: Independent Variable: The people chosen for the experiment. Dependent Variable: Height and upper limb length. IV. Constants: Units of measure, the…

I’d like to start by talking about the value of fifty percent. Fifty percent equals one half of a whole, it is more than zero, but less than one hundred percent, which is whole. Fifty percent is incomplete. Everyone in this room can agree with these statements as fact. It’s a simple matter of taking the value of something. But what about value in people? I am fifty percent Hispanic. I am one half. I am more Hispanic than not, but I am less than hundred percent. If these statements coincide…
