Improvisation as “real time foresight”

The concept of improvisation, while now recognized in organization studies, has been neglected in strategy studies. We suggest that one of the reasons for this is the dominance of a structural view of strategy and competition. Alternative views, such as the Austrian school or those that stress the Red Queen effect, emphasize the process-based nature of competition. In fast-changing environments, speed and reaction are central attributes, which render the traditional separation between planning and execution untenable. In these contexts, improvisation, the convergence of planning and execution, becomes a paradoxical form of “real time foresight”: organizations screen trends, spot opportunities, actively wait and/or act with speed to seize the moment.     

The Value of Badger Populations and Control of Tuberculosis in Cattle in England and Wales: A Note

This note reports on the results of a choice experiment survey of 400 people in England and Wales, conducted to estimate the value that society places on changes to the size of the badger population. The study was undertaken in the context of the possible need to reduce the badger population by culling to help control bovine tuberculosis in cattle. The study found that people were concerned about the problem of bovine tuberculosis in cattle, which was reflected in their willingness to pay to control the disease, and gave a relatively low value to changes in the size of the badger population (within limits). However, people did not like the idea of a policy that intentionally killed large numbers of badgers and had a relatively very high willingness to pay not to have such a policy.     

Guest editorial: perspectives on sustainable consumption

The typical guest editorial within a special issue of a journal will explain the theme of the special issue, introduce the different contributions that follow, outline the contributions that each makes and identify the common threads that connect them. By contrast, this editorial article seeks to provide an overview which explores the broader context for the challenges that are presented by the pursuit of ‘sustainable consumption’ as a field of scholarship, a form of behaviour and a public policy goal. It explores some of the complexities involved in understanding sustainable consumption, and the ways in which conventional approaches to understanding consumption and consumer behaviour may be insufficient to understand and promote sustainable consumption.     

Managing Middlescence

They make up more than half your workforce. They work longer hours than anyone else in your company. From their ranks come most of your top managers. They're your midcareer employees, the solid citizens between the ages of 35 and 55 whom you bank on for their loyalty and commitment. And they're not happy. In fact, they're burned out, bored, and bottlenecked, new research reveals. Only 33% of the 7700 workers the authors surveyed feel energized by their work; 36% say they're in dead-end jobs. One in three is not satisfied with his or her job. One in five is looking for another. Welcome to middlescence. Like adolescence, it can be a time of frustration, confusion, and alienation. But it can also be a time of self-discovery, new direction, and fresh beginnings. Today, millions of midcareer men and women are wrestling with middlescence-looking for ways to balance work, family, and leisure while hoping to find new meaning in theirjobs. The question is, Will they find it in your organization or elsewhere? Companies are ill prepared to manage middlescence because it is so pervasive, largely invisible, and culturally uncharted. That neglect is bad for business: Many companies risk losing some of their best people or-even worse-ending up with an army of disaffected people who stay. The best way to engage middlescents is to tap into their hunger for renewal and help them launch into more meaningful roles. Perhaps managers can't grant a promotion to everyone who merits one in today's flat organizations, but you may be able to offer new training, fresh assignments, mentoring opportunities, even sabbaticals or entirely new career paths within your own company. Millions of midcareer men and women would like nothing better than to convert their restlessness into fresh energy. They just need the occasion-and perhaps a little assistance-to unleash and channel all that potential.     

基于预编码与导频分配的大规模MIMO导频污染抑制

导频污染问题是限制大规模多输入多输出(MIMO)系统性能的主要影响因素。针对这个问题,提出了一种基于改进预编码和最优导频分配策略的大规模MIMO系统导频污染抑制算法。首先,在系统下通过基于改进遗传优化算法的最大化信干噪比(SINR)预编码算法,获得最优预编码矩阵;然后,通过基于用户信道条件优劣的最优导频分配策略对每个小区用户进行导频分配,从而实现大规模MIMO系统导频污染抑制。通过Matlab仿真结果可知,相对于传统的SINR预编码算法,所提算法的复杂度降低了65%左右,而导频污染抑制性能提升了30%左右。该算法能够有效抑制导频污染,提升大规模MIMO系统的性能。     

Liberty,equality and consumerism in state education: exploring liberal angst under New Labour

This paper aims to explore aspects of consumerism in state secondary education in England, the dilemmas posed by the educational market‐place for a category we describe as the ‘resourced liberal egalitarians’ and the resolution of these dilemmas offered by the actions of prominent Labour Party parents‐as‐consumers. Having outlined the individual and societal significance of education, the ideological and ‘economic’ dimensions of educational consumption are explored in order to locate the category ‘resourced liberal egalitarians’. This group's dilemmas are then explained in the context of the strengthening of the market principle and the polarizing of the market‐place within education. These together increase the stakes of protecting their own children's interests while simultaneously exacerbating the inegalitarian character of the education system, a situation which they find distasteful. The final section looks at how the actions of prominent Labour Party figures address this angst through their own actions as parent‐consumers of state education.     

Evidence on the Relationship between Low Income and Poor Health: Is the Government Doing Enough?

The government's report, Opportunity for All: Tackling Poverty and Social Exclusion (Department of Social Security, 1999), identified poor health as one of the major problems associated with low income. However, much of the available evidence on the relationship between income and health is of little help in forming policies to reduce health inequalities, as it has tended to be based on cross‐section surveys and is therefore unable to shed much light on causal effects. Here, we make use of two British longitudinal datasets to examine the longer‐term influences of income on health within a life‐course perspective. We then use the results of our analysis to provide a brief critical assessment of the likely success of the government's anti‐poverty strategy in reducing health inequalities. A more detailed assessment of government policy in this respect can be found in Benzeval et al. (forthcoming).     

Religiosity,ethical ideology,and intentions to report a peer's wrongdoing

Peer reporting is a specific form of whistelblowing in which an individual discloses the wrongdoing of a peer. Previous studies have examined situational variables thought to influence a person's decision to report the wrongdoing of a peer. The present study looked at peer reporting from the individual level. Five hypotheses were developed concerning the relationships between (1) religiosity and ethical ideology, (2) ethical ideology and ethical judgments about peer reporting, and (3) ethical judgments and intentions to report peer wrongdoing.Subjects read a vignette concerning academic cheating, and were asked to respond to a question-naire concerning the vignette. Data were analyzed using structural equation methodology.Results indicated that religiosity was positively associated with an ethical ideology of non-relativism. Individuals whose ethical ideologies could be described as idealistic and non-relativistic were more likely to state that reporting a peer's cheating was ethical. In turn, individuals who believed reporting a peer's cheating was ethical were more likely to say that they would report a peer's cheating.
