seconds to complete the TUG test, then he or she is at a higher risk for falling (CDC, 2013). The researchers state that the inter-rater reliability of the TUG test is very high among hospital in-patients and community-dwelling older adults (Herman, Giladi, & Hausdorff, 2011). Additionally, the researchers state that the TUG test has a moderate test-retest reliability in a large study of older adults, and the TUG test was able to identify fallers from non-fallers with an 87% sensitivity and…
because, if a random error were to occur, and the diluted Aquasol concentration does not result in the desired concentration, the validity, reliability, and precision of the results is majorly decreased. Whereas if the Aquasol concentrations were already previously diluted in a lab by professionals, or were bought in the correct concentrations, the reliability, validity, and precision of the results would have been have been significantly better. Another weakness in this experimental design was…
Introduction The selection process is a deliberate effort to help the organization find suitable candidates who are likely to perform with maximum effectiveness (Aquinas, 2009). The design of the selection process becomes even more critical when hiring refugees from the African Community Center of the Ethiopian Community Development Council (ECDC/ACC). While this refugee resettlement agency provides the Commercial Food Safety and Service (CFaSST) program to help refugees get training in the…
nonverbal communication skills client might do better drawing than verbally discussing issues. Weaknesses that are included within the test include the inconsistency of the test due to the multiple versions and interpretations available that affect the reliability and validity of the test. Another weakness is multicultural concerns pertaining language and cultural barrier for test takers. These concerns can also affect the results and interpretations, which can cause adverse effects to do the…
The values for the Axial length and Keratometry obtained through the various methods as mentioned above should be consistent so as to rule out sources of error. The need to repeat these measurements can be obtained based upon the HOLLADAY CRITERIA which states: Repeat Km if: Km47D for either eye Difference between the two eyes >1 D Corneal cylinder doesnot correlate well with the refractive cylinder Repeat AL if: AL< 22mm AL> 25mm Difference between the two eyes > 0.3 mm Doesnot…
Prompt 2. The purpose of this paper is to discuss the lightness constancy and how it works. Including how the visual system works with constancies, to properly attribute uniform color to a surface. The way to go about the task is with an example. Imagine there are two surfaces next to each other. One appears uniformly white since the light source is evenly distributed throughout the surface. The other has surface patches, a non-uniformity in the light being reflected off of the surface. So…
alarm, leading to a Panorama investigation this week, entitled ‘Could a Robot do my Job?’” Jane Merrick (2015) mentioned in an Independent Newspaper. Although automation seems like a threat they are plenty of positive aspects to it such as the reliability, productivity and job increases. The concept of automation have been tossed around quite a bit lately and wrongfully miss judged at that. Automation is “the state of being operated automatically” according to the…
and reliability is a fairly new phenomenon; it was thought that analyzing the findings was not needed because this particular type of research deals with real-time (interviews or observations). However, it was discovered that researchers showed some form of bias in their studies. The belief is that the studies were bias because most researchers are looking for some form of funding. Therefore, many are now finding themselves having to prove their qualitative studies with validity/reliability…
indicators or theoretically related to the constructs in question. In order to determine if the quality of the products of an organization is good or bad through quality assessment ratings, one needs to understand the meaning of quality, the characteristics of quality and criteria for quality. The quality might be perceived differently by various departments of an organization…
