Economic and social leader–member exchange relationships and follower performance

This exploratory study investigated the link between economic and social leader–member exchange relationships and follower work performance and organizational citizenship behavior. Instead of viewing exchange relationships between leaders and subordinates on a continuum from low to high quality, we conceptualize social and economic exchange relationships as relationships with different qualities, rather than different levels of quality. Data from 552 followers and 78 leaders supported our two-dimensional model of leader–member exchange relationships. Furthermore, an economic leader–member exchange relationship was negatively related to both work performance and organizational citizenship behavior. As expected, positive relationships were obtained for a social leader–member exchange relationship and work performance and organizational citizenship behavior. Implications for practice and future research are discussed.     

Unitarian ideals and professional diversity in social work practice—the case of Sweden

Attempts to articulate a common core of social work are numerous as is the claim that there exists a ‘true’ or general social work. This article presents results from research on the organisational settings of Swedish social work. Social work managers in 100 middle sized municipalities have been interviewed by means of an extensive interview manual. Data are analysed using quantitative methods. The results demonstrate that since the 1980s specialisation has become the strongest organisational trend. Functional specialisation (division of child welfare, social assistance and social work with substance abusers) is the standard way of organising social work and in many municipalities specialisation has gone much further. An integrated or generic organisational model, which was the imperative of the 1970s, seems to exist only in the smallest municipalities. Some of the organisational changes can be described as short-lived fashions. Specialisation as such seems, however, to be an institutionalised strategy to solve social problems and as a response to expectations from the environment. These results are discussed against the background of the notion of social work as a coherent profession with an identifiable common core and a mutual arsenal of methods.

Comparing customer satisfaction across industries and countries

Although aggregate satisfaction measures continue to proliferate, their value in making broad-based comparisons remains unclear. This study uses arguments from the economics, psychology, sociology and marketing domains to predict systematic differences in aggregate customer satisfaction across both industries and countries. These predictions are tested using a database created from three broad-based national satisfaction surveys in Sweden, Germany and the United States. The results reveal that, across countries, satisfaction is highest for competitive products, lower for competitive services and retailers, and lower still for government and public agencies. However, the differences vary by country. Satisfaction is also predictably lower in Sweden and Germany compared to the US, and shown to change systematically in Sweden over time. Methodological differences do not appear to limit the comparability of the aggregate satisfaction measures. Overall the study supports the use of national indices for making meaningful comparisons of satisfaction on a broad scale.     

Does CERN procurement result in innovation?

Innovation is stated to be one of the most powerful engines for economic growth in firms, markets and nations today. It is therefore not surprising that policy-makers would like to see innovations as a benefit of publicly spent money; making innovations an additional aim of public procurement (public procurement for innovation). The aim of the paper is to analyse the impact of a science organization's procurement practices on innovation. The intention is also to show how different and contradicting goals and expectations regarding public procurement are described and acted upon by the science organization and its suppliers, and to what extent the outcome of public procurement is innovation. Empirically, the study addresses how the European Organization for Nuclear Research, i.e. CERN, works with procurement; and how their procurement in turn affects CERN's suppliers. Based on a large case study in which more than 100 interviews were conducted over a time period of 8 years, the study contributes to the understanding of the limitations CERN’s procurement rules put on interaction and on innovation. The understanding of the implications of restricting interaction, but also the understanding of the reasons why these rules are put into place, and the dilemmas that follow, are all important contributions.     

The Muscatine children's obesity data reanalysed using pattern mixture models

A set of longitudinal binary, partially incomplete, data on obesity among children in the USA is reanalysed. The multivariate Bernoulli distribution is parameterized by the univariate marginal probabilities and dependence ratios of all orders, which together support maximum likelihood inference. The temporal association of obesity is strong and complex but stationary. We fit a saturated model for the distribution of response patterns and find that non-response is missing completely at random for boys but that the probability of obesity is consistently higher among girls who provided incomplete records than among girls who provided complete records. We discuss the statistical and substantive features of, respectively, pattern mixture and selection models for this data set.     

Native American casino gambling in Arizona: A case study of the Fort McDowell reservation

Since Congress passed the American Indian Gambling Regulatory Act (IGRA) in 1988, there has been an explosion in the number of gambling casinos located on Native American reservations. It is estimated that in 1994 the total net revenue from 81 Native American casinos exceeded $2.3 billion dollars. As the number of Native American casinos grows along with the volume of gambling activity, opposition increases from states, the established gambling industry hurt by lost revenues, and groups with moral objections to gambling. This article reports on an effort to measure the economic impact of the Fort McDowell casino located near Phoenix, Arizona. The article discusses the casino's history and current operations. Next, it explains the use of an input-output model to compute the impact of casino's income and employment effects on the economy of Maricopa County. It is estimated that the casino is responsible for 2,483 new jobs, and an increase of approximately $80.35 million in regional output. Additional information is necessary to more accurately assess both the benefits and costs of the casino. Unfortunately, subsequent efforts to collect additional data have been unsuccessful. The conclusion discusses why, and raises questions regarding Native American gaming.An earlier version of this paper was presented at the 9th International Conference on Gambling and Risk Taking, May 31–June 3, 1994, Las Vegas, Nevada. This research was funded by a FGIA grant from Arizona State University. The author expresses his appreciation to the referees who provided substantial guidance in improving the original paper. Any remaining errors are mine.     

The relative risk aversion hypothesis of educational choice

Analysing young people's educational choices, we derive and test implications of a relative risk aversion hypothesis: that educational choices are made so as to minimize the risk of ending up with a lower level of education than one's parents. These implications are in general different from what one would expect from human capital theory. We use a unique data set which combines data from administrative registers on young people's pathways through the educational system and their family background with survey data on their academic abilities at lower secondary school. The evidence is partly in favour of the relative risk aversion hypothesis. Received: 19 August 1999/Accepted: 10 January 2001 All correspondence to Eskil Heinesen.
