Centralized vs. decentralized computing : organizational considerations and management options

The long-standing debate over whether to centralize or decentralize computing is examined in terms of the fundamental organizational and economic factors at stake. The traditional debate is examined and found to focus predominantly on issues of efficiency vs. effectiveness, with solutions based on a rationalistic strategy of optimizing in this tradeoff. A more behavioralistic assessment suggests that the driving issues in the debate are the politics of organization and resources, centering on the issue of control. The economics of computing deployment decisions is presented as an important issue, but one that often serves as a field of argument that is based on more political concerns. The current situation facing managers of computing, given the advent of small and comparatively inexpensive computers, is examined in detail, and a set of management options for dealing with this persistent issue is presented

The importance of social worlds: an investigation of peer relationships [Wider Benefits of Learning Research Report No. 29]

In the following report, we investigate the developing social worlds in late primary school, exploring the patterns in children’s general peer relationships, their closer and more significant friendships and bullying behaviours. Using cluster analysis, we identify unique groups of children characterized not only by their experiences of bullying and victimization, but the support and satisfaction they receive from their friendships and interactions between the ages of 8 and 10. We also expand past research by examining how children’s early development (ages 3 to 4) may predict their later designation as bullies and/or victims, and whether peer clusters relate to children’s contemporaneous and later adjustment

The impact of pupil behaviour and wellbeing on educational outcomes

A review of previous literature suggests that wellbeing and learning are associated with one another; however, there is less information on how multiple dimensions of wellbeing together predict later changes in educational outcomes for children and teenagers. The simultaneous examination of different dimensions of wellbeing across primary and secondary school will help clarify their relative importance during the key stages of schooling. This project examines how various dimensions of children’s wellbeing are associated with their educational outcomes, including a review of relevant literature and an analysis using data from the Avon Longitudinal Study of Parents and Children (ALSPAC)

Filamentary Star Formation: Observing the Evolution toward Flattened Envelopes

Filamentary structures are ubiquitous from large-scale molecular clouds (few parsecs) to small-scale circumstellar envelopes around Class 0 sources (~1000 AU to ~0.1 pc). In particular, recent observations with the Herschel Space Observatory emphasize the importance of large-scale filaments (few parsecs) and star formation. The small-scale flattened envelopes around Class 0 sources are reminiscent of the large-scale filaments. We propose an observationally derived scenario for filamentary star formation that describes the evolution of filaments as part of the process for formation of cores and circumstellar envelopes. If such a scenario is correct, small-scale filamentary structures (0.1 pc in length) with higher densities embedded in starless cores should exist, although to date almost all the interferometers have failed to observe such structures. We perform synthetic observations of filaments at the prestellar stage by modeling the known Class 0 flattened envelope in L1157 using both the Combined Array for Research in Millimeter-wave Astronomy (CARMA) and the Atacama Large Millimeter/Submillimeter Array (ALMA). We show that with reasonable estimates for the column density through the flattened envelope, the CARMA D-array at 3mm wavelengths is not able to detect such filamentary structure, so previous studies would not have detected them. However, the substructures may be detected with CARMA D+E array at 3 mm and CARMA E array at 1 mm as a result of more appropriate resolution and sensitivity. ALMA is also capable of detecting the substructures and showing the structures in detail compared to the CARMA results with its unprecedented sensitivity. Such detection will confirm the new proposed paradigm of non-spherical star formation.Comment: 9 pages, 10 figures. Accepted by Ap

Cultural Values and Important Possessions: A Cross-Cultural Analysis

The logic behind globalized advertising appeals is based on the premise that cultural value systems are converging. Yet, there is no clear agreement regarding the superiority of standardized campaigns vs. localized ones. One reason for this lack of agreement deals with the extent to which various cultures share similar values. The goal of this study is to apply a relatively new framework dealing with value differences developed by Schwartz [Adv. Exp. Soc. Psychol. 25 (1992) 1.] to New Zealand and the USA by looking at the connection between these values and possessions. The hypotheses received mix support. The results confirm that New Zealanders are higher in Harmony and Affective Autonomy, and these values did, in part, affect possessions and reasons for owning them. New Zealanders’ most valued possessions were for environmental reasons, but they were no more likely to mention enjoyment reasons than Americans. New Zealanders also did not mention recreational possessions as more important, contrary to one of the hypotheses. Nonetheless, the similarities between NZ and the USA were much greater than the differences. The study provides valuable insight into how the meanings of important possessions differ across cultures and illustrates the need to understand these differences when designing marketing communications and positioning products in foreign markets

The fundamental group of reductive Borel-Serre and Satake compactifications

Let $G$ be an almost simple, simply connected algebraic group defined over a number field $k$, and let $S$ be a finite set of places of $k$ including all infinite places. Let $X$ be the product over $v\in S$ of the symmetric spaces associated to $G(k_v)$, when $v$ is an infinite place, and the Bruhat-Tits buildings associated to $G(k_v)$, when $v$ is a finite place. The main result of this paper is an explicit computation of the fundamental group of the reductive Borel-Serre compactification of $\Gamma\backslash X$, where $\Gamma$ is an $S$-arithmetic subgroup of $G$. In the case that $\Gamma$ is neat, we show that this fundamental group is isomorphic to $\Gamma/E\Gamma$, where $E\Gamma$ is the subgroup generated by the elements of $\Gamma$ belonging to unipotent radicals of $k$-parabolic subgroups. Analogous computations of the fundamental group of the Satake compactifications are made. It is noteworthy that calculations of the congruence subgroup kernel $C(S,G)$ yield similar results.Comment: 21 pages, 1 figure, uses Xy-pic 3.8.6; in version 2, title changed to more accurately reflect main result, expository material on congruence subgroup problem removed, many small corrections and improvements in expositio
