Entry characteristics and academic performance of students in a master of pharmacy degree program in the United Kingdom

Objective. Evaluate the characteristics of a cohort of Master of Pharmacy (MPharm) students upon entry and examine any associations between entry qualifications, type of school attended, socioeconomic deprivation, age and academic performance in the MPharm programme. Methods. A retrospective cohort analysis of data recorded on Aston University’s central database for each individual exiting the MPharm programme during the five year period 2005-6 – 2009-10 (n=644). Results. Entrants were disproportionately drawn from socioeconomically deprived areas and independent (private) schools. Achievement prior to admission was related to the type of school attended but not to deprivation. Performance on the programme was not related to type of school or deprivation but was strongly correlated with prior achievements. Conclusions. Prior achievement is the most important predictor of performance on the MPharm programme but the superior prior achievement of independent school pupils is not seen at the point of graduation. This may have implications for admissions policies.

Organizational commitment profiles and job satisfaction among Greek private and public sector employees

Recent research into organizational commitment has advocated a profiles-based approach. However, with the exception of Wasti, published findings are confined to North American samples. This article examines the relationships between organizational commitment profiles and job satisfaction in Greece. Greek organizations have rarely been the subject of detailed examination, so the study provides baseline information regarding levels of organizational commitment and job satisfaction in Greece. Both private sector (N = 1119) and public sector (N = 476) employees in Greece were surveyed, as this sectoral distinction is regularly associated with different patterns of job-related attitudes. The contrasts between Greek and Anglo-American values present a new challenge to the profiles approach. The results confirm the utility of the profiles approach to the study of organizational commitment. Affective organizational commitment was found to be most influential with respect to levels of intrinsic and extrinsic job satisfaction. This concurs with other studies of the behavioural outcomes of commitment. Copyright © 2007 Sage Publications.

Registered social landlords: private enterprise (f)or public good?

Millions of homes previously owned by councils have been transferred to the ownership of registered social landlords. Many of these are run as private companies under the principles first set out in the Combined Code of Corporate Governance. This articled considers whether it is appropriate to apply both the principles of the Code and regulation from the Housing Corporation as forms of control over such companies, and whether extensive government regulation negates the requirement for a board comprising independent directors expected to make strategic decisions while overseeing the executive. Conflict is created when trying to run these companies with a unitary board structure adhering to Combined Code principles while considering the wider interests of the community. It is questioned whether it is inefficient to try to meet these two objectives simultaneously and whether this system produces the best results for the community, the lenders and the end users.

Managers' personal values as drivers of corporate social responsibility

In this theoretical paper, motives for CSR are considered. An underlying assumption is that the commercial imperative is not the sole driver of CSR decision-making in private sector companies, but that the formal adoption and implementation of CSR by corporations could be associated with the changing personal values of individual managers. These values may find expression through the opportunity to exercise discretion, which may arise in various ways. It is suggested that in so far as CSR initiatives represent individuals' values, so the “responsibility” in evidence is less obviously “corporate.” Our emphasis on personal initiative is intended to counter a tendency to view the corporation as the agent, and may serve to remind us that individuals can, indeed, make a difference.

Effects of grain size and microstructure on threshold values and near threshold crack growth in powder-formed Ni-base superalloy

Threshold stress intensity values, ranging from ∼6 to 16 MN m −3/2 can be obtained in powder-formed Nimonic AP1 by changing the microstructure. The threshold and low crack growth rate behaviour at room temperature of a number of widely differing API microstructures, with both ‘necklace’ and fully recrystallized grain structures of various sizes and uniform and bimodal γ′-distributions, have been investigated. The results indicate that grain size is an important microstructural parameter which can control threshold behaviour, with the value of threshold stress intensity increasing with increasing grain size, but that the γ′-distribution is also important. In this Ni-base alloy, as in many others, near threshold fatigue crack growth occurs in a crystallographic manner along {111} planes. This is due to the development of a dislocation structure involving persistent slip bands on {111} planes in the plastic zone, caused by the presence of ordered shearable precipitates in the microstructure. However, as the stress intensity range is increased, a striated growth mode takes over. The results presented show that this transition from faceted to striated growth is associated with a sudden increase in crack propagation rate and occurs when the size of the reverse plastic zone at the crack tip becomes equal to the grain size, independent of any other microstructural variables.

A statistical physics perspective on alignment-independent protein sequence comparison.

Motivation: Within bioinformatics, the textual alignment of amino acid sequences has long dominated the determination of similarity between proteins, with all that implies for shared structure, function, and evolutionary descent. Despite the relative success of modern-day sequence alignment algorithms, so-called alignment-free approaches offer a complementary means of determining and expressing similarity, with potential benefits in certain key applications, such as regression analysis of protein structure-function studies, where alignment-base similarity has performed poorly. Results: Here, we offer a fresh, statistical physics-based perspective focusing on the question of alignment-free comparison, in the process adapting results from “first passage probability distribution” to summarize statistics of ensemble averaged amino acid propensity values. In this paper, we introduce and elaborate this approach.
