Trade and the Gains from Diversity: Why Economists Failed to Predict the Consequences of Brexit

In this brief article I explain why the expectation amongst economists that Brexit means Britain will experience significant economic losses, thanks to the reversal of the gains from specialisation, is incorrect. The background assumptions regarding comparative advantage are false and cannot inform real-world situations. However, this is not the same as to suggest Britain as a post-Brexit country will follow successful trade policies.     

Healthy Active Living: A Residence Community–Based Intervention to Increase Physical Activity and Healthy Eating During the Transition to First-Year University

Abstract

Objective: To examine the effects of a Healthy Active Living (HAL) community intervention on moderate-to-vigorous physical activity (MVPA), fruit and vegetable consumption (FVC), and psychosocial mediators of physical activity among students transitioning into university. Methods: Sixty undergraduate students were assigned to reside in either the HAL community or no-treatment control residence and completed questionnaire measures at the beginning and end of the academic year. Results: Students living in the HAL community reported significantly more MVPA (F[1, 58] = 19.93, p <.001, η_p² =.26) and greater FVC (F[1, 56] = 3.12, p =.08, η_p² =.05) compared with controls. Participants in the HAL condition also scored significantly higher in action planning (F[1, 58] = 4.79, p <.05, η_p² =.08), partially mediating the effect of the intervention on MVPA. Conclusion: A peer-delivered healthy lifestyles intervention targeting first-year university students appears to be effective in preserving or enhancing health behaviors and cognitions during their transition into university life.     

Maintaining the Gains: What Worked in the Year after Brief Family Therapy

Brief family therapy, including single session therapy, is widely used to provide a timely and responsive service for children with emotional and behavioural problems. However, there is surprisingly little information about how these children and families fare in the longer term. The brief family therapy program described here was directed toward children with problems of moderate severity. Child Behaviour Checklists (CBCL) were completed by parents before, three months after, and twelve months after therapy; 110 parents also participated in semi‐structured telephone interviews twelve months after therapy. Parents' CBCL ratings showed a significant decrease in children's problems after therapy, which were maintained over the subsequent year, although some children continued to experience difficulties. Parents generally found brief therapy a helpful experience. Ways to strengthen the preventive possibilities of brief therapy work will be identified at both a practical and conceptual level.     

Social Capital Across the Life Course: Age and Gendered Patterns of Network Resources1

Despite increasing research interest in network dynamics and cumulative advantage/disadvantage processes, little remains known about how social capital varies across the life course. While some researchers suggest that social capital increases with age and others argue the opposite, this study tests these contradictory assertions by analyzing multiple indicators of social capital from a nationally representative data set on working‐age U.S. respondents. The findings reveal evidence of both social capital accumulation and decline. Social resources from occupational contacts tend to increase with age, but eventually level off among older respondents. Changes in voluntary memberships follow a similar pattern. However, daily social interaction is negatively associated with age. Overall, the results suggest that social capital embedded in occupational networks tends to accumulate across the career, even in the face of a general decline in sociability. The study also uncovers gender differences in these social capital trajectories that are linked to the distinct life experiences of men and women.     

Conference report: Sixth annual meeting of the international visual sociology association visual studies workshop,July 15, 16, 17, 1988

How does the visual construction process of news influence the resulting cultural images? In this study of Time magazine's creation of a 1990 documentary, “The Palestinians, A Long, Bloody Road to Nationhood,” I first look at possible meanings in the printed photographs, and then explore how Time's institutional processes of story conceptualization, photo assignment, editing, and layout each create parameters for meaning. The discussion shows how Time editors ultimately construct their product using visual affect as an assumed first level of meaning.     

Quantifying biodiversity

Darwin's Theory of Evolution explains the astonishing variety of life on earth. But many species are vanishing. We pass resolutions to slow the decline in biodiversity but we cannot tell whether those resolutions are met because we have no effective way of measuring biodiversity. Steve Buckland believes there are solutions.     

Cooperation and Knowledge Transfer within Buyer–Supplier Relationships: The Moderating Properties of Trust,Relationship Duration and Supplier Performance*

This paper examines the effect of relational factors on knowledge transfer within strategic buyer–supplier exchange. Prior research examining inter‐firm knowledge transfer has focused almost exclusively on horizontal forms of governance such as strategic alliances and joint ventures, whilst research on vertical forms, such as buyer–supplier relationships, is limited. We test the effect of four important relational properties: cooperation, trust, relationship duration and supplier performance. Quantitative data, gathered from 104 UK manufacturing firms in eight industry sectors, are used to analyse the hypothesized relationships through a moderated hierarchical regression model. Our study provides support for the importance of considering relational factors in the transfer of knowledge at the inter‐organizational level. In particular, the results indicate that knowledge transfer is positively influenced by the extent of cooperation, but that this relationship is moderated by the level of trust and the performance of the supplier firm. Managerial implications for these findings and future directions for research are then offered.
