Background: Smartphones are ideal for promoting physical activity in those with little intrinsic motivation for exercise. This study tested three hypotheses: H1 - receipt of social feedback generates higher step-counts than receipt of no feedback; H2 - receipt of social feedback generates higher step-counts than only receiving feedback on one's own walking; H3 - receipt of feedback on one's own walking generates higher step-counts than no feedback (H3). Methods: A parallel group randomised controlled trial measured the impact of feedback on steps-counts. Healthy male participants (n = 165) aged 18-40 were given phones pre-installed with an app that recorded steps continuously, without the need for user activation. Participants carried these with them as their main phones for a two-week run-in and six-week trial. Randomisation was to three groups: no feedback (control); personal feedback on step-counts; group feedback comparing step-counts against those taken by others in their group. The primary outcome measure, steps per day, was assessed using longitudinal multilevel regression analysis. Control variables included attitude to physical activity and perceived barriers to physical activity. Results: Fifty-five participants were allocated to each group; 152 completed the study and were included in the analysis: n = 49, no feedback; n = 53, individual feedback; n = 50, individual and social feedback. The study provided support for H1 and H3 but not H2. Receipt of either form of feedback explained 7.7 % of between-subject variability in step-count (F = 6.626, p < 0.0005). Compared to the control, the expected step-count for the individual feedback group was 60 % higher (effect on log step-count = 0.474, 95 % CI = 0.166-0.782) and that for the social feedback group, 69 % higher (effect on log step-count = 0.526, 95 % CI = 0.212-0.840). The difference between the two feedback groups (individual vs social feedback) was not statistically significant. Conclusions: Always-on smartphone apps that provide step-counts can increase physical activity in young to early-middle-aged men but the provision of social feedback has no apparent incremental impact. This approach may be particularly suitable for inactive people with low levels of physical activity; it should now be tested with this population. © 2016 The Author(s).

Despite the generally positive contribution of supply management capabilities to firm performance their respective routines require more depth of assessment. Using the resource-based view we examine four routines bundles comprising ostensive and performative aspects of supply management capability - supply management integration, coordinated sourcing, collaboration management and performance assessment. Using structural equation modelling we measure supply management capability empirically as a second-order latent variable and estimate its effect on a series of financial and operational performance measures. The routines-based approach allows us to demonstrate a different, more fine-grained approach for assessing consistent bundles of homogeneous patterns of activity across firms. The results suggest supply management capability is formed of internally consistent routine bundles, which are significantly related to financial performance, mediated by operational performance. Our results confirm an indirect effect of firm performance for 'core' routines forming the architecture of a supply management capability. Supply management capability primarily improves the operational performance of the business, which is subsequently translated into improved financial performance. The study is significant for practice as it offers a different view about the face-valid rationale of supply management directly influencing firm financial performance. We confound this assumption, prompting caution when placing too much importance on directly assessing supply management capability using financial performance of the business. © 2015 Elsevier B.V.

This paper considers how perceptions of costs and benefits can influence the association between personality and risky choice behaviour. We assessed perceptions and behaviours in six domains (ethical; investment; gambling; health and safety; recreational; social) using the DOSPERT and measured personality using the NEO PI-R. Results from structural equation modelling showed that personality had a direct effect on risky choice behaviour in four domains (social, ethical, gambling and recreational risk-taking). In addition, perceived costs and benefits mediated the relations between personality and risk-taking in the five domains (social, ethical, gambling, recreational and investment risk-taking). Evidence for a mechanism that integrates both direct and indirect effects of personality on behaviour is discussed.

China's rapid growth in recent decades can be attributed in large part to the emergence of a vibrant private sector, which now accounts for around three quarters of the economy. Despite government pronouncements in support of private small businesses, public policy and institutions to support private sector development have been slow to emerge and address their needs. However, many privately owned enterprises are in need of assistance, affected by internal capability constraints such as a lack of management and leadership skills and by an external environment that still privileges state-owned enterprises. Although policy makers may have had other policy priorities in the past, and private enterprises have been able to survive and grow without inputs of professional advice and support, we argue that in the future small and medium-sized enterprises in China will require appropriate and effective business support to continue to grow. In this context we consider two interventions designed to build institutional capacity to provide business support at a local level and the barriers to be overcome if an effective framework for state promotion of privately owned small businesses is to be established.

With the increasing infiltration of online social networking into the everyday life of the younger generation, higher education appears to be a lucrative platform for deploying social networks in an academic context. This paper suggests research questions and opens a discussion in relation to managing knowledge on online social networking in academic settings and beyond. Extant research provides a useful lens into the applications of social networking sites in learning and teaching or at the stages of employability and career management in student life. A limited consideration in current research has been given to exploring capabilities of social networking for lifelong learning and its role in the entire student lifecycle. The potential opened by online social networking in the area of knowledge accumulation and knowledge sharing is yet to be properly addressed by researchers. Therefore more attention is needed to identify the overarching issues of social networking applications in Higher Education (HE) settings. Based on a broad literature review this paper draws attention to some implications for HE institutions of exploiting knowledge resources with online social networks. © Springer-Verlag Berlin Heidelberg 2013.
