Closeness,loneliness, support: Core ties and significant ties in personal communities

Past research has introduced further distinctions within the strong ties that form our personal communities. This work aimed at a comparison between core and significant ties in terms of their emotional closeness to ego, the social provisions that are exchanged, the relationship maintenance behaviours reported, and ego's loneliness. Measures for all these variables were assessed in a survey study. Evidence for a trade-off between the number of ties and their level of intimacy was obtained such that having more core ties was associated with lower levels of intimacy. Distinct signatures for friends from both sets of ties emerged for friendship maintenance behaviours and social provisions exchanged. Further, social and emotional loneliness were differentially related to the number and the intimacy of core and significant ties.     

The application of dynamic programming in United Kingdom companies

Dynamic Programming (or DP as it is commonly known) is a mathematical programming method which would appear to be a very powerful technique for use in management decision problems. A great number of theoretical texts have been written on the mathematics of DP and a few articles have been published on the more practical aspects, but DP has remained very much on the theoretical shelf as far as practising management has been concerned. This paper gives the results of a survey carried out at the beginning of 1972 and is intended to provide some insight into the use of DP in real management problems in U.K. companies and to show what sort of problems are apparently restricting its use. The findings demonstrate that several firms have used DP in various applications with considerable success. There are also some enlightening comments on the difficulties involved, and on the future potential of DP in industry.     

Institutions and the shaping of different forms of entrepreneurship

Entrepreneurship is a broad concept encompassing a wide range of activities, from the Schumpertian ideal associated with innovation to simply creating a job for oneself. Because we ask about national differences in entrepreneurship, we consider national differences for entrepreneurship, the institutions, and if these relate to the emergence of different types of enterprise. We propose that national patent grants represent innovation and that national self-employment rates represent job replacement. Interestingly, we found that institutional factors that determine self-employment and innovation may act in opposite directions: what encourages self-employment might discourage innovation and vice-versa.     

Single‐Session Approaches to Therapy: Time to Review

In 2001 Bloom produced a comprehensive review of single‐session approaches to therapy (SST). In his paper he outlined the concept of single session therapy and considered the evidence that could be used to support implementation of single session approaches. At the time, Bloom's was probably the most comprehensive review of research on single session therapy available: he considered papers that provided overviews of approaches to developing and delivering single‐session treatment, as well as papers that used controlled and uncontrolled methods to evaluate outcomes. What I will do in this paper is to informally review the literature on single session therapy that has been published since Bloom's 2001 paper. The paper is not intended as a formal review or meta‐analysis of research data, partly because the field still does not have such methodological rigour.     

Shifting the Goalposts? Analysing Changes to Performance Peer Groups Used to Determine the Remuneration of FTSE 100 CEOs

This paper examines year‐on‐year changes to the composition of performance peer groups used for relative performance evaluation in setting CEO pay in FTSE 100 companies and finds evidence of peer selection bias. The authors find that firms keep their peer groups weak by excluding relatively stronger performing peers. They also show that peer selection bias is less pronounced in firms with higher institutional investor ownership, which suggests that institutional investors might be aware of the risks of peer selection bias. The results suggest that peer group modifications can be viewed, at least in part, as an expression of managerial rent‐seeking.     

When the snowball fails to roll and the use of ‘horizontal’ networking in qualitative social research

Snowball sampling is frequently advocated and employed by qualitative social researchers. Under certain circumstances, however, it is prone to faltering and even failure. Drawing on two research projects where the snowball failed to roll, the paper identifies reasons for this stasis. It goes on to argue that there are alternative forms of networking that can be developed by the qualitative social researcher in lieu of snowballing. Specifically, when research momentum fails to build, rather than drilling down ‘vertically’ through social networks, we argue that the researcher can move ‘horizontally’ across social networks and cast the sampling and recruitment net wide and shallow rather than deep. This change in emphasis can, we argue, make the difference between a project failing and a project succeeding, and points to the importance of a variegated understanding of the social networks on which our social research depends.     

Single Session Interventions: An Example of Clinical Research in Practice

Single session consultations seem to be an efficient and effective way of providing therapeutic interventions at a time of increasing demands for services and shrinking resources. Though ‘one-off’ consultations have a long clinical history, specific interest in their use was sparked by Talmon's (1990) observation that 78% of his clients who had had only one consultation had experienced improvement in their presenting problems. Several Australian studies have supported Talmon's advocacy of this approach (Boyhan, 1996; Hampson, O'Hanlon, Pentony and Cramby, 1994; Price, 1994) but have significant methodological flaws. The present study used a pre–post methodology to assess the effectiveness of single session interventions and explored whether family dynamics impacted on changes in the presenting problem and in level of coping. The results indicated significant changes in both. Family pride or morale was identified as a major factor in positive response to the interventions. The implications for the use of single sessions and for further clinically based research are discussed.     

European Youth Gang Policy in Comparative Context

The past decade has seen increased reports of street gangs across a range of contexts. In Europe, anxieties over street‐based youth has led to the development of gang‐specific policies across a range of jurisdictions, most notably the UK. Following a similar pattern of policy mobility in criminal justice, many of these policies have origins in the US system. In this review of international gang policy developments, we critically examine a number of these policies in a comparative context ‐ including gang policing units and intelligence databases ‐ and interrogate their efficacy. Drawing on cogent examples from the UK, we argue for caution in adopting US gang intervention tactics due to the lack of empirical evidence relating to their applicability or efficacy, and the corresponding potential for discrimination toward the most marginalised and socially excluded children and young people in society.
