To understand the work experiences of men who sexually offend against children, the authors conducted a qualitative study on a sample of 8 outpatients in mandated treatment. The results, based on both interview and quantitative data, highlighted the reciprocal influence of work and sexual offending and ways in which the offense affected participants' psychosocial and career stability. Participants who were rated as making the most favorable progress by their therapists ranked work as less salient than home and family, leisure, and community service, although they were relatively satisfied with their current jobs. Work was more salient than other life roles, but less satisfying for participants who were making less progress in treatment. Participants reported a loss of job security and career status, as well as restricted opportunities for vocational change and advancement.

The ash cloud resulting from the 2010 eruption of Eyjafjöll caused severe disruption to air travel across Europe but as a geological event, it is not unprecedented. Analysis of peat and lake sediments from northern Europe has revealed the presence of microscopic layers of Icelandic volcanic ash (tephra). These sedimentary records, together with historical records of Holocene ash falls, demonstrate that Icelandic volcanoes have generated substantial ash clouds that reached northern Europe many times. Here we present the first comprehensive compilation of sedimentary and historical records of ash-fall events in northern Europe, spanning the last 7000 years. Within this period ten tephra layers have been identified in the Faroe Islands, 14 in Great Britain, 11 in Germany, 38 in Scandinavia and 33 in Ireland. Seven ash fall events have been historically documented prior to the Eyjafjöll 2010 event. Ash fall events appear to be more frequent in the last 1500 years, but it is unclear whether this reflects a true increase in eruption frequency or dispersal, or is an artefact of the records themselves or the way they have been generated. In the last 1,000 years, volcanic ash clouds reached Northern Europe with a mean return interval of 53 ± 8 years (the range of return intervals is between 6 and 112 years). Modelling using the ash records for the last millennium indicates that for any 10 year period there is a 17% probability of tephra fallout event in Northern Europe. These values must be considered as conservative estimates due to the nature of tephra capture and preservation in the sedimentary record.

Information systems professionals must pay attention to online customer retention. Drawing on the relationship marketing literature, we formulated and tested a model to explain B2C user repurchase intention from the perspective of relationship quality. The model was empirically tested through a survey conducted in Northern Ireland. Results showed that online relationship quality and perceived website usability positively impacted customer repurchase intention. Moreover, online relationship quality was positively influenced by perceived vendor expertise in order fulfillment, perceived vendor reputation, and perceived website usability, whereas distrust in vendor behavior negatively influenced online relationship quality. Implications of these findings are discussed. © 2011 Elsevier B.V. All rights reserved.

Despite huge investment over the past 10 years, improving outcomes for looked-after children remains elusive. A challenge for practitioners, researchers and policy-makers has been the absence of a shared conceptual framework for considering and responding to the needs of looked-after children. A second challenge relates to the measurement of outcomes. This article considers the measurement of outcomes and the multiple factors that contribute to outcomes for looked-after children. These include factors proximate to: the young person; birth family; placement; care system; children’s services; intra-agency dynamics; inter-agency dynamics; commissioning agents; and societal level. It then proposes an organising framework which provides the basis for reflecting on how multiple variables can interact to effect outcomes for looked-after children. The ecological perspective outlined in this article aims to facilitate reflection on the complex interplay between looked-after children and their environments and thereby to act as an aid to targeting interventions more effectively and efficiently.

Nearly all psychological research on basic cognitive processes of category formation and reasoning uses sample populations associated with large research institutions in technologically-advanced societies. Lopsided attention to a select participant pool risks biasing interpretation, no matter how large the sample or how statistically reliable the results. The experiments in this article address this limitation. Earlier research with urban-USA children suggests that biological concepts are (1) thoroughly enmeshed with their notions of naive psychology, and (2) strikingly human-centered. Thus, if children are to develop a causally appropriate model of biology, in which humans are seen as simply one animal among many, they must undergo fundamental conceptual change. Such change supposedly occurs between 7 and 10 years of age, when the human-centered view is discarded. The experiments reported here with Yukatek Maya speakers challenge the empirical generality and theoretical importance of these claims. Part 1 shows that young Maya children do not anthropocentrically interpret the biological world. The anthropocentric bias of American children appears to owe to a lack of cultural familiarity with non-human biological kinds, not to initial causal understanding of folkbiology as such. Part 2 shows that by age of 4-5 (the earliest age tested in this regard) Yukatek Maya children employ a concept of innate species potential or underlying essence much as urban American children seem to, namely, as an inferential framework for understanding the affiliation of an organism to a biological species, and for projecting known and unknown biological properties to organisms in the face of uncertainty. Together, these experiments indicate that folkpsychology cannot be the initial source of folkbiology. They also underscore the possibility of a species-wide and domain-specific basis for acquiring knowledge about the living world that is constrained and modified but not caused or created by prior nonbiological thinking and subsequent cultural experience.

This paper challenges the recent suggestion that a new financial elite has evolved which is able to capture substantial profit shares for itself. Specifically, it questions the assumption that new groups of financial intermediaries have increased in significance primarily because there is evidence that various types of financial speculators have played a similarly extensive role at several junctures of economic development. The paper then develops the alternative hypothesis that, rather than being a recent development, the rise of these financial intermediaries is a cyclical phenomenon which is linked to specific regimes of capital accumulation. The hypothesis is underpinned by historical data from the US National Income and Product Accounts for the period from 1930 to 2000, which suggest that the activities of `mainstream' financial intermediaries have been accompanied by the frequently countercyclical activities of a `speculative' sector of security and commodity brokers. Based on the combination of this qualitative and quantitative evidence, the paper concludes that the rise of a speculative financial sector is a potentially recurrent phenomenon which is linked to periods of economic restructuring and turmoil.

Bees are major pollinators of Angiosperms and therefore their apparent decline is of importance for humans and biodiversity. We synthesise results of 12 recent reviews to provide a global picture of the threats they face. Habitat loss is the major threat to bee diversity, whilst invasive species, emerging diseases, pesticide use, and climate change also have the potential to impact bee populations. We suggest that future conservation strategies need to prioritise (i) minimising habitat loss, (ii) making agricultural habitats bee-friendly, (iii) training scientists and the public in bee taxonomy and identification, (iv) basic autecological and population genetic studies to underpin conservation strategies, (v) assessing the value of DNA barcoding for bee conservation, (vi) determining the impact of invasive plants, animals, parasites and pathogens, and (vii) integrating this information to understand the potential impact of climate change on current bee diversity.

Thorstein Veblen was a turn of the 20th century American economist concerned with the implications of financial capitalists directing the means of production. Veblen proposed that the rationality of "material science" as practiced by the "production engineers" is fundamentally different from the rationality of market capitalism. If this claim is valid, our previous contentions regarding accounting, as a facilitating technology, for administrative evil warrant reconsideration. Veblen's position provides a historical perspective on one dimension of administrative evil that is generally unquestionably accepted, especially within accounting. That is, technology, such as accounting and the related information systems, is amoral, and it is only through ideologically instigated applications that any moral value accrues. We discuss administrative evil and the role of instrumental rationality generally, and accounting specifically, in creating it. Veblen's characterization of financial capitalism and production engineers and his arguments for the primacy of economic efficiency versus "pecuniary gain" provide a basis for evaluating the legitimating action. We consider how Veblen's work relates to notions of instrumental rationality and then undertake a critical assessment of the ideas. Some of Veblen's ideas, while utopian, might be seen as an elixir for the detrimental influences of financial capital; however, at best, they provide a placebo for the ills of administrative evil and, as such, do not provide an amoral basis for legitimating the associated accounting systems.
