Timing,order and durability of new product advantages with imitation

This research examined the effects of timing, order and the durability of first mover advantages by analyzing the stock market reactions to new product introductions and imitations. The major findings are that both timing and order of moves are important and that rival reactions undermine the durability of first mover advantages. More specifically, (1) early and fast movers achieve greater gains than late and slow movers, and (2) first movers suffer at the time of new product imitations.

A Falling of the Veils: Turning Points and Momentous Turning Points in Leadership and the Creation of CSR

Contemporary organizations often reciprocate to society for using resources and for affecting stakeholders by engaging in corporate social responsibility (CSR). It has been shown that CSR has a positive impact on employee attitudes. However, not all employees may react equally strongly to CSR practices. Based on socio-emotional selectivity theory (Carstensen in Science 312:1913–1915, 2006), we contend that the effect of CSR on employee satisfaction will be more pronounced for older than for younger employees, because CSR practices address those emotional needs and goals that are prioritized when people’s future time perspective decreases. In one multi-source field study (N = 143) and one experimental study (N = 500), we demonstrate that CSR indeed has a stronger positive effect on employee satisfaction for older relative to younger employees. Accordingly, engaging in CSR can be an attractive tool for organizations that aim to keep their aging workforce satisfied with their job.     

Moral Repair in the Workplace: A Qualitative Investigation and Inductive Model

The topic of moral repair in the aftermath of breaches of trust and harmdoing has grown in importance within the past few years. In this paper, we present the results of a qualitative study that offers insight into a series of key issues related to offender efforts to repair interpersonal harm in the workplace: (1) What factors motivate offenders to make amends with those they have harmed? (2) In what ways do offenders attempt to make amends? (3) What outcomes emerge from attempts to make amends? Drawing from the findings, we build an inductive model intended to guide future business ethics and management inquiry and research in this area.     

Unintended consequences in demarketing antisocial behaviour: project Bernie

Unintended consequences are recognised as a potential risk for well-intentioned social marketing interventions and as a comparatively under-researched topic in the field. This case study uses an intervention tackling deliberate grassfires to explore the application of social marketing in a novel context, its potential effectiveness in demarketing antisocial behaviours and the potential of such interventions to generate positive and negative unintended consequences. The intervention’s evaluation confirms social marketing’s potential value in tackling ingrained antisocial behaviours within communities. It also revealed unexpected benefits accruing from changes within the target community, within the sponsoring fire service and in the relationship between the two. The paper concludes by discussing the implications of potential unexpected and unplanned consequences for intervention planning, conduct and evaluation.     

基于深度学习的毫米波系统波束成形

针对高移动用户在毫米波系统中用户与基站之间频繁切换增大延迟开销问题,提出了一种新颖的集成深度学习协调波束成形（Deep Learning Coordinated Beamforming,DLCBF）解决方案。该方案通过协调多个基站同时为一个移动用户服务,接收用户上行导频序列和预编码码本训练模型,进而预测最佳下行波束向量,克服了大型天线阵列毫米波系统中选取最佳波束成形向量需要的巨大训练开销。仿真结果表明,所提方案与传统的毫米波波束成形策略相比有更高的频谱有效率。     

Beach safety education for primary school children

Childhood drowning remains a serious public health problem worldwide. The Australian Water Safety Council has set as one of its highest priorities the reduction of drowning deaths in children aged 0–14 years. However, concerns have recently been raised that many students completing primary school still lack the ability to recognize potential aquatic risks, cope with emergencies or assist someone else in danger. In this study, 107 primary school children aged 11–12 completed a one day training programme led by surf lifesaving instructors. Pre, post and eight week follow-up measures showed statistically significant improvements in recognition of the red ‘beach closed’ flag, aquatic safety signs, how to identify a rip current and choosing the safest place to swim at a beach that included a rip current in the picture. Following training students were more willing to provide first aid assistance to family members and friends in an emergency situation. Findings reinforce the value of school-based training that provides a general foundation for aquatic safety, with the caveat that current programmes must be evaluated to ensure their content has a robust prevention focus.     

Firm ownership and productivity: a study of family and non-family SMEs

Motivated by a lack of consensus in the current literature, the objective of this paper is to reveal whether family firms are more or less productive than non-family firms. As a first step, this paper links family business research to the theoretical notion that family involvement has an effect on the factors of production from a productivity standpoint. Second, by using a Cobb–Douglas framework, we provide empirical evidence that family labour and capital indeed yield diverse output contributions compared with their non-family counterparts. In particular, family labour output contributions are significantly higher, and family capital output contributions significantly lower. Interestingly, differences in total factor productivity between family and non-family firms disappear when we allow for heterogeneous output contributions of family production inputs. These findings imply that the assumption of homogeneous labour and capital between family and non-family firms is inappropriate when estimating the production function.     

Realisations of Venture Capital Investments: The Case of Management Buy-outs in the UK

One of the most rapidly developing sectors of the financial services industry in the UK has been venture capital, and with it the growth of management buy-outs. As these markets have matured, increasing attention is being paid to issues associated with the realisation of gains for both institutions and equity-holding management. This article seeks to contribute to this area by examining the issues involved in the realisation of investments in management buy-outs. Based on detailed interviews with 24 managers of buy-outs which have exited, and on information drawn from the Centre for Management Buy-out Research database, the article considers the relative merits of flotations, trade sales, capital restructurings, secondary buy-outs, share redemptions etc. The article also addresses the agency cost issues involved in controlling buy-outs to enable institutions to achieve realisation of their investments at a price and timing which enable their targets to be met.     

Sales promotion—playing to win?

In recent years, below‐the‐line promotion has begun to shed its “Cinderella” image, and is starting to attract the sort of marketing budgets and academic attention that was previously only given to mass‐media advertising. However, there is a general consensus that sales promotion is still neither managed effectively, nor understood thoroughly when compared to more high‐profile above‐the‐line promotion. Improving the understanding and use of sales promotion will require academics and practitioners to analyse and understand each of the very different below‐the‐line techniques and their individual merits. This article is one of two which takes a detailed look at the use of sales promotion competitions.
