Drawing on the current research in general leadership, we propose that a process ontology is relevant and rewarding for project leadership studies. We argue that project leadership can be studied as the ongoing social production of direction through the construction of actors’ space of action, involving continuous construction and reconstruction of (1) past project activities and events; (2) positions and areas of responsibility; (3) discarded, ongoing, and future issues; and (4) intensity, rhythm, and pace. Through an ethnographic case study of an organizational change project, we show how space of action and hence the project direction are in constant flux and becoming. 相似文献

While Facebook usage has seen explosive growth, scant research has explored returns on advertising dollars marketers invest in this emerging medium. Our two-stage study of 18- to 25-year-old college students suggests that many of the advertising dollars consumer goods firms spend on Facebook are likely wasted. This study highlights that, in addition to staying in touch with friends and relatives, Facebook users are primarily motivated by three desires: (1) to voyeuristically peer into others’ lives, (2) to create a distinctive identity for themselves, and (3) to act on their inner narcissistic tendencies. These motivations also make them poor prospects for advertisers, as users seem disinterested in Facebook ads and disengaged from marketers’ attempts to build brands. Herein, we discuss challenges for marketers, as well as opportunities for building brands and driving sales via Facebook. 相似文献

Advergames are gaining recognition as a captivating environment. Although several flow models have determined online games usage, no previous model has explored determinants of positive attitudes toward advergames. The objectives included development and empirically testing of a model of flow experience and its determinants of attitudes toward advergames. Positive attitudes toward advergames were partially explained by the flow experience. The model revealed that challenges offered by the gameplay were an important predictor of flow, followed by telepresence and players’ skills. Contrary to expectations, arousal significantly impacted attitudes toward advergames but not flow. Implications for advertisers and web developers are discussed. 相似文献

The link between income inequality and economic growth has raised many debates in the literature and has generated a large spectrum of results over time. This paper aims at analyzing the relationship between economic growth and income inequality, as well as their macroeconomic and institutional determinants in the New Member States, between 2000 and 2009. In the presence of a set of explicative variables, the economic growth influences the social inequality through a U-shaped relationship. Health, education and gross capital formation generate different direct and indirect effects on income inequality as the per capita GDP growths, while the transition indicators are found to be either common or specific determinants of inequality and growth. 相似文献

The regulatory environment in which the Australian life insurance industry operates has its antecedents in two major periods of legislative intervention. The first established the principle of 'freedom with disclosure' in the 1870s, which has since formed the basis of the regulatory approach. In the 1940s, the second refined the concept in the context of a general recognition of an interventionist approach to financial markets. It is suggested that regulation of the life insurance market in Australia came about not in response to problems associated with market failure but in reaction to external influences not directly related to conditions in the Australian life insurance industry. This was impacted not only on the timing of intervention but on the approach taken as well. 相似文献

This paper presents a review of non‐experimental methods for the evaluation of social programmes. We consider matching and selection methods and analyse each for cross‐section, repeated cross‐section and longitudinal data. The methods are assessed drawing on evidence from labour market programmes in the UK and in the US. 相似文献

The development of the insurance industry in Australia in the twentieth century was fundamentally shaped by a collusive code of conduct called the tariff. This arrangement, established to overcome problems of uncertainty, initially benefited both tariff and non-tariff firms by enhancing market stability. It also reduced competition. The collusive agreements gradually broke down, however, as new entrants and products entered the market in the 1950s. Self-regulation gradually gave way as the 'rules of the game' changed. The result was a period of instability before new competitive practices, and more direct and specific regulatory requirements emerged in the 1970s. 相似文献

Traditional estimation theory generally starts from point estimators, and based on them confidence regions with given confidence
level are constructed. However, this approach works only in some special cases and, even more severe, it is based on the unrealistic
but mathematical necessary assumption of a generally unbounded parameter space.
The procedures derived in this paper, start from a bounded measurement range which contains the potential values of the parameter
of interest. For given measurement range and given reliability requirement measurement procedures including a point estimator
are developed. The result are complete measurement procedures for distribution parameters. Most precise procedures are derived
and called complete Neyman measurement procedures. 相似文献

Many economic games have multiple equilibria, some of which are better than others for everyone involved. Such coordination games are of special interest to economists because they raise the possibility that a group of individuals or even a whole economy might become mired in an unfavorable situation. This paper explains how to use playing cards in the classroom to implement an economic game with multiple, Pareto-ranked equilibria. Discussion can focus on policies and institutions that promote coordination on better outcomes. Use: This experiment can be used in introductory economics to teach concepts of team production and coordination and in intermediate microeconomics to teach game-theoretic concepts of Nash equilibrium and Pareto optimality. Time required: Five minutes for reading instructions, 20 minutes for decision making, and about 15 minutes for discussion. Materials: You will need one or more decks of playing cards, each deck accommodating 26 people. One copy of the instructions should be made for each person. Payment to a randomly selected individual is optional and will require about a dollar or two. 相似文献
