Computer Simulations Improve University Instructional Laboratories

Laboratory classes are commonplace and essential in biology departments but can sometimes be cumbersome, unreliable, and a drain on time and resources. As university intakes increase, pressure on budgets and staff time can often lead to reduction in practical class provision. Frequently, the ability to use laboratory equipment, mix solutions, and manipulate test animals are essential learning outcomes, and “wet” laboratory classes are thus appropriate. In others, however, interpretation and manipulation of the data are the primary learning outcomes, and here, computer-based simulations can provide a cheaper, easier, and less time- and labor-intensive alternative. We report the evaluation of two computer-based simulations of practical exercises: the first in chromosome analysis, the second in bioinformatics. Simulations can provide significant time savings to students (by a factor of four in our first case study) without affecting learning, as measured by performance in assessment. Moreover, under certain circumstances, performance can be improved by the use of simulations (by 7% in our second case study). We concluded that the introduction of these simulations can significantly enhance student learning where consideration of the learning outcomes indicates that it might be appropriate. In addition, they can offer significant benefits to teaching staff.     

COMPARING QUALITY IN EUROPE

As higher education begins to operate increasingly in a European framework, consequences for the assurance of quality in higher education are bound to become evident. A pilot study to develop a methodology for the comparison of quality across different higher education systems is described. The project involved comparison of ten study programmes in economics in Germany, the Netherlands, and the United Kingdom. A design derived from general considerations about the concept of quality and about the nature of higher education and different systems incorporated two stages. First was the collection of information and the processing of this information into manageable data sets; second was the assessment of the information by way of peer review. The proceedings and principal findings of both stages followed the overview of the project design. The article concludes by highlighting some implications of this pilot project for the future of quality assurance in higher education on a European scale.     

Knowledge sources of entrepreneurship: Firm formation by academic,user and employee innovators

Innovative new ventures are at the heart of economic development, particularly when these startups are created by employee, academic, and user innovators. We synthesize across literature streams examining each phenomena to document distinctions between firms originating from different “knowledge contexts.” We then integrate the knowledge context into Teece's (1986) theoretical framework identifying factors that impact a firm's ability to profit from innovation. Doing so allows us to develop stylized facts and predictive propositions pertaining to differences in the innovative contributions, roles played in shaping industrial dynamics and evolution, and performance outcomes for startups stemming from the three entrepreneurial origins. These propositions provide unique insights into the causes of patterns of industry evolution, contribute to theory in the areas of entrepreneurship and industry evolution, and yield important policy and managerial implications.     

Reading Canonical Texts in Multicultural Classrooms

This essay explores the complexity of imposing texts that are considered part of the English literary canon on students from multicultural backgrounds. It considers the rhetoric of the coalition government, in the recent drive to emphasize the importance of the literary heritage and return to English culture and how its impact has been felt in the classroom. It focuses mainly on the teaching of The Scarlet Letter to a Year 9 class and the issues presented when teaching it to a class of learners from very different ethnic backgrounds. It considers whether the true value of studying these texts is worthwhile for very different reasons from the social and cultural ones that have driven recent educational policy in England.

Use of glycated hemoglobin (HbA<Subscript>1C</Subscript>) and impaired glucose tolerance in the screening of undiagnosed diabetes in the Malaysian population

Although HbA_1C is widely accepted as a useful index of mean blood glucose in type 2 diabetic patients its usefulness as screening test for diabetes has been controversial. The present study was undertaken to determine whether the level of HbA_1C predicted diabetes in a prediabetic group of subjects. Plasma lipids, oral glucose tolerance, HbA_1C was determined in 90 normal control subjects, 57 offspring of one type 2 diabetes mellitus parent and 11 diagnosed type 2 diabetes mellitus individuals. The mean age of participants was 44.5 yrs (not significantly different amongst the three groups) and the mean body mass index was 26.8 (not significantly different amongst the three groups). Two hours after a 75 g glucose challenge, the offspring had a significantly higher plasma glucose level (mean = 7.1 mmol/L, p value = 0.002) than the normals. Similarly the HbA_1C values were higher in the offspring than in the normals (mean = 5.78%, p value = 0.016). Besides the significantly higher values for oral glucose tolerance test and HbA_1C, the diabetics also were significantly higher for triglycerides (mean = 2.25mmol/L), total cholesterol (mean = 6.24mmol/L) and systolic blood pressure (mean = 138.45mm Hg) than the offspring (P value = 0.031, 0.006, 0.010) and the normals (P value = 0.026, 0.018, 0.002) respectively. The mean values of diastolic blood pressure, LDL cholesterol and HDL cholesterol were not significantly different amongst the three groups.     

Racial hierarchy and masculine space: Participatory in/equity in computational physics classrooms

ABSTRACT

Background and Context

Computing is being integrated into a range of STEM disciplines. Still, computing remains inaccessible to many minoritized groups, especially girls and certain people of color. In this mixed methods study, we investigated racial and gendered patterns of equity and inequity in high school physics classrooms incorporating computational modeling, with an emphasis on group work.     

Biochemical Indicator of Sickle Cell Disease: Preliminary Report from India

Blood biochemistry has significant effect on pathophysiology of human body. Recently few studies found the association of biochemical abnormalities in sickle cell patients. Sickle cell disease showed clinical variability where African ancestors have severe phenotype than Indian sicklers. Our aim was to evaluate the biochemicals in sickle cell patients and their effect on severity. Here we present the comparative biochemical levels in sickle cell patients as well as controls. Sickle cell patients diagnosed by HPLC and biochemical analysis done by Beckman-auto analyzer. T test applied for statistical analysis. Result showed the renal abnormality lesser in patients and related biochemical within the normal range and statistically not significant. Electrolytes, hepatic enzymes, alkaline phosphatase and glucose were elevated and statistically significant (P value <0.05). Observation of the study concludes the biochemical abnormality play a significant role in sickle cell patient’s physiopathology and can be used to management of the disease.
