Developing Life Skills : Perceptions of Graduates of the Adult, Non-Traditional Business and Management Programs at Indiana Wesleyan University

Problem. Indiana Wesleyan University teaches all of its adult courses using 10 skills as a foundation. This study determined the perceived attitudes of its graduates regarding the importance of and their relative progress in these 10 areas. Method. A survey questionnaire was developed and a stratified random sample of graduates was surveyed. A two-way analysis of variance was used to analyze the differences and interactions among the graduates based on two variables: major and gender. Results. Graduates perceived the following four skills as very important : Problem Solving, Oral Communication, Writing Effectively, and Ethics. Six skills were perceived as important : Teamwork, Lifelong Learning, Critical Thinking, Reading Materials, and Christian World View. Graduates further perceived themselves as evidencing considerable progress in the following eight skills: Teamwork, Writing Effectively, Oral Communication, Problem Solving, Lifelong Learning, Critical Thinking, Information Literacy, and Ethics, and some progress in the remaining two skills: Reading Materials and Christian World View. Conclusions. While considered to be important, the skill of the Christian World View was perceived by graduates as the least important of the skills. Graduates felt that although they evidenced some progress, the Christian World View skill was perceived as evidencing the least amount of development. Problem Solving and Oral Communication skills were perceived as the most important skills, and Teamwork was perceived by graduates as the skill evidencing the most progress

Evaluación de criterios de selección de modelos probabilísticos: validación con series de valores máximos simulados

Se realizó un estudio de Monte Carlo para determinar la validez del empleo de la prueba del error estándar de ajuste como criterio de selección en el análisis de frecuencias. Dicho estadístico se comparó con los estadísticos de prueba de Kolmogorov-Smirnov, Cramer-Von Mises y AndersonDarling. Las distribuciones elegidas para el propósito de comparar estos estadísticos fueron la gamma, Weibull, Gumbel, log-normal y log-logística. Los resultados obtenidos recomiendan el uso de muestras con tamaño de por lo menos n = 50 para tener un buen desempeño de las pruebas de Anderson-Darling y error estándar de ajuste. El empleo de las pruebas de Kolmogorov-Smirnov y Cramer-Von Mises no es del todo recomendable en hidrología, ya que para obtener un desempeño aceptable se necesitan muestras más grandes de las que normalmente se tienen en esta disciplina

Epicardial propranolol administration for ventricular arrhythmias in dogs: matrix formulation and characterization

The effect of propranolol on the prevention of ventricular tachycardia/fibrillation (VT/VF) due to acute coronary ischaemia was studied in dogs. A series of propranolol-polymer controlled release matrices in slab configuration using various polyurethanes and a polyurethane-silicone rubber copolymer were formulated and characterized. In general, drug release in vitro occurred with an initial burst phase followed by an exponentially declining delivery rate; the silicone rubber containing copolymer preparation had more sustained release properties than did pure Polyurethane matrices. In the animal studies, dogs underwent 5-hourly 10 min complete occlusions of the left anterior descending coronary artery (LAD), followed by 50 min normal perfusion. During non-drug occlusions VT occurred at a frequency of 1.22 +/- 0.12 episodes/min. A propranolol-polyurethane matrix (30% w/w, 28-42 mg) was placed on the ischaemic zone of the left ventricular epicardium immediately after the fifth occlusion. After an hour of drug delivery a sixth occlusion took place. The number of arrhythmia episodes both before and after drug were quantified and compared. The time to ventricular fibrillation (when present) and the mean blood pressure were also assessed. The drug patch delivered propranolol at a dose of 140 +/- 45 [mu]g/kg by the conclusion of the 1 h study period. Therapeutic drug levels were achieved in the peripheral blood samples (8.7-43.7 ng/ml) and were enhanced in coronary venous samples (360.9-556.2 ng/ml). Reduction of blood pressure and proarrhythmic events following epicardial controlled release propranolol administration were noted but were not statistically significant. Arrhythmia episodes before and after propranolol were not found to be significantly different (VT/min 1.02 +/- 0.31 and 1.22 +/- 0.12). The occlusion time until VF occurred was also not significantly different before versus after propranolol (t = 5.38 +/- 0.86 and 5.28 +/- 0.48 min). Therefore, despite attaining clinically therapeutic plasma levels, epicardial administration of propranolol was not found to be effective for the prevention of VT/VF due to acute ischaemia.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/30361/1/0000763.pd
