Femoral Popliteal Bypass A femoral popliteal bypass is a procedure to go around (bypass) a blocked artery in the leg. The artery may become blocked with plaque, which is a buildup of fat. Arteries carry oxygen and nutrients to the body. The femoral artery is in the upper part of the leg. It is the main artery that carries blood to the leg. Popliteal arteries are in the back of the knee. These arteries take blood to the lower part of the leg. This procedure uses a graft to bypass the blocked…

Lawrence, the president of Downing Digital Healthcare Partners said, “Customers just aren’t aware of the prevalence of sudden cardiac arrest.” Each year in the United States over 424,000 victims are being affected all ages, in Hawaii, Native Hawaiians are 1.7 times (over 70%) more likely to die from heart disease than other race. To prevent this from happening to all citizens, CFL (Certification for Life) wants to increase funding for more access to an AED. Our goal as the CFL is to train…

Title Anatomical variation of the superior thyroid artery and its relation to the external laryngeal nerve. Introduction The thyroid gland is the largest endocrine gland located in the anterior triangle of the neck. It consists of two lobes, right and left, connected by an isthmus in the middle. The thyroid gland is mainly supplied by the superior thyroid artery, the first branch of the external carotid artery, and the inferior thyroid artery, a branch of the thyrocervical trunk of the…

repair them; I remember him saying it’s either a straight forward case or a complicated one. Ours was the second type of transplant. It was mesmerizing and breathtaking to see how the kidney became viable and pinkish after he connected it to the external iliac artery and vein. I enjoyed observing the surgeon while checking for any bleeding at the suture lines to make sure everything went smooth. I remember the next day when we were rounding and visiting the gentleman in his room, he was super…

has internal validity? Explain No. it is impossible to prove conclusively that a study has internal validity. This is because there are many threats to internal validity and it is sometime difficult to control all of them, especially the loss of subjects. 2. In chapter 6, we discussed the concept of external validity. In what ways, if any, are internal and external validity related? Can a study have internal validity but not external validity? If so, what about the reverse External and…

responsibility of the researcher to try to maximize construct, statistical and external validity in both frequency claims, such as self-reporting, and association claims like correlational research (lecture, 09/01/2015). Construct validity deals with the accuracy and specificity of variables and measurements. External validity is a way of determining how research can be applied to the outside world. Lastly, statistical validity deals with the accuracy and significance of the findings following…

research design. Internal validity, external validity, construct validity, and statistical conclusion validity are all important terms to think about when comparing and organizing your research. Internal validity can be defined by three different terms. There is going to need to be a co variation of cause and effect, which is when x is caused by y, temporality means that the cause must precede the effect in time, and last it will have no alternate explanation. External validity is data that has…

Research Question Do punitive (punishment-based) interventions work in curtailing repeated truancy rates within a school environment? Research Design A 2 x 2 between- subjects factorial design will be implemented by combining a natural and longitudinal study design. Age (primary and secondary) and punitive punishment (fines or after-school detention) acting as our two independent variables, and rate of truancy acting as the dependent variable. Justification Natural-Longitudinal Research…

to scientific validity and is based on Parker's (1993) article on the same. This article is relevant to the gaming industry as most of the points regarding the validity of a research can be related to the gaming industry and it is further explained in this paper. Scientific Validity Types of validity In this paper the scientific validity of research is categorized into four types of validity: internal, external, statistical conclusion, and construct validity. Each of these validity have their…

1) For each of the studies, how did Golub, Gilbert, and Wilson (2009) operationally define the positive expectations? How did they operationally define affect? In the laboratory studies the positive expectation were operationally defined by presenting the personality classification A to the 13 participants in both 1a and 1b. The classification was shown by the computer. In the field study the positive expectation was operationally defined by asking students to…
