impacted by an ice storm that hit the New York metropolitan area and caused the cancellation of about 1,200 flights over a six-day period. After our recovery from the storm, we implemented a multiphased strategy to improve our overall operating reliability, allow our crewmembers to better handle irregular operations (which includes pre-emptive cancellations for severe weather), and improve customer communications. ” My Opinion Even though JetBlue experienced uncontrollable situation factors…

A Critical Evaluation of the Reliability and Validity of the National Adult Reading Test, (NART). Introduction The national adult reading test otherwise known as NART, was devised in 1982 by Hazel Nelson, as a device to determine premorbid intelligence, and is used frequently in patient assessments and research. As an estimate of IQ, this test is utilised on individuals with declining mental health that is affecting their functioning ability, particularly cases of dementia and often…

of the angle of the extension of knee joints. Other traditional and universal way of measuring knee extension is using goniometer and inclinometer. The method of measuring ROM has to be reliable and valid. According to Gajdosik and Bohannon, the reliability is the consistency and repeatability of ROM measurement (Bohannon and Gajdosik, 1987). In a more specific way, it means that among consecutive measurements, the variables and conditions such as the use of instrument and also the procedure…

Past ORT Device Reliability Data for Icewine with Montana had typically shown high variability in results. This was due to high stress in the OCAs that often lead to Reliability Failures. However, it was shown that after several weeks dwell the results would show significant improvement. All OCA Lots from the Taein Last Time Buy (LTB) were pre-Screened at Device-Level before they were accepted for MP input at TPK. Almost Half of the LTB OCA Lots were rejected after pre-screening for Montana.…

A geriatric social worker develops a very lengthy scale to assess the degree of staff sensitivity to the needs of residents in nursing homes. This scale is designed to be completed by both staff and residents. According to Rubin & Babbie (2016), this scale may be vulnerable to common sources of systematic and random error. As discussed by Rubin & Babbie (2016), sources of systematic error in measurement scales originate from biases during data collection in which a pattern emerges indicating…

risks: • he reliability level of the software delivered by the subcontractor is below the required reliability level and as a result the reliability of the software does not fulfill the performance specifications. • The interface having new control device is not defined. So the driver of the device may take more time then scheduled to implement it. Following is the brief difference between project management and risk management.…

The article, “Standard Error of Measurement” by Leo M. Harvill from East Tennessee State University, provided a general introduction of Standard Error of Measurement (SEM). First, it introduced the basic concepts of test reliability. An obtained score or a raw score refers to the number of points obtained by an examinee. The obtained score could be influenced by several factors such as the ambiguity of test items, the fatigue of the examinee, and these factors make the obtained score unlikely to…

Critically discuss whether the widespread use of the Myers Briggs Type Indicator is justified by its reliability and validity The role of personality measuring instruments in the workplace has been under debate and there have been different viewpoints regarding the matter. Some researchers argue that personality measures do not aid the hiring process as accurately as they should (Christiansen, Goffin, Johnston, & Rothstein, 1994; Rosse, Stecher, Miller, & Levin, 1998), while others oppose…

Description of the child and the context The subject of our mean length utterance study is A.N., a four year old Caucasian female. A.N. is the firstborn child in a family of four, living with both of her parents and a younger sister about 8 months old. Since she lives in a dormitory, as her parents are Resident Heads, she interacts with college students on a regular basis, which may contribute to accelerated language acquisition, in terms of her increased exposure to vocabulary. On the day of…

As seen in Table 6, reliability analysis for four factors revealed Cronbach’s alpha values of 0.92 for Factor 1; 0.85 for Factor 2; 0.82 for Factor 3; and, 0.77 for Factor 4. All of factors in turn yielded high levels internal consistency reliability. Also, the overall internal consistency reliability of all of four subscales was 0.91, which proves a very high level of internal consistency reliability. Study 2: Confirmatory Factor Analysis Method A total of…
