Effects of product placements on attitudes have rarely been the subject of scientific research so far. Furthermore, existing findings are partially contradictory??a fact that has been explained with the impact of intervening variables both on the side of the stimulus and of the recipient. Especially the design of the placement is said to have an influence on whether the intended effect shows up or not. In this context the prominence/salience of the placement is of importance. The following study is based on an experiment (n?=?221) testing how the prominence of placements affects the attitudes of recipients. For this, we measure attitudes not only by explicit questioning using a semantic differential, but also with the help of an implicit association test. In doing so we react to criticism of the methodological one-sidedness of past examinations of the effects of product placement, most of them solely relying on self-reports to measure attitudes. The experiment shows that the implicit measurement of attitudes uncovers effects that would have remained in the dark if only explicit questioning had occurred. The study also reveals that the presentation of subtle placements results in more positive brand attitudes; this relation is moderated by recipients?? programme assessment.     

The ties that bind: Buyer-supplier relations in the construction industry

This study considers the consequences of Inter Organisational relations at two levels: the micro level of the individual, and the macro level of the organisation. Merging Transaction Cost Economics with theories on the Social Embeddedness of relations, the paper tackles several hypotheses about problems in buyer–supplier relations. We amend the general hypothesis, as has been put forward by other researchers, that having a common past in combination with an expected common future in business will reduce the likelihood that problems and conflicts occur. Our focus lies on whether this shared past and future can preclude problems better when the organisational relations are at the micro level. Our analyses of survey data from 448 contractor–subcontractor relations from the contractor's perspective in the construction industry reveal mixed support for effects of a shared past or future. We hardly find any of the expected positive effects of a shared past on supplier performance. However, we do find support for the hypothesis that a larger likelihood of future business with the same business partner has a stronger (negative) effect on the occurrence of problems if the expected future business is at the level of individuals (instead of at the level of organisations).     

A review of statistical methods in the analysis of data arising from observer reliability studies (Part I)*

Summary This paper reviews research situations in medicine, epidemiology and psychiatry, in psychological measurement and testing, and in sample surveys in which the observer(rater or interviewer) can be an important source of measurement error. Moreover, most of the statistical literature in observer variability is surveyed with attention given to a notational unification of the various models proposed. In the continuous data case, the usual analysis of variance (ANOVA) components of variance models are presented with an emphasis on the intraclass correlation coefficient as a measure of reliability. Other modified ANOVA models, response error models in sample surveys, and related multivariate extensions are also discussed. For the categorical data case, special attention is given to measures of agreement and tests of hypotheses when the data consist of dichotomous responses. In addition, similarities between the dichotomous and continous cases are illustrated in terms of intraclass correlation coefficients. Finally, measures of agreement, such as kappa and weighted-kappa, are discussed in the context of nominal and ordinal data. A proposed unifying framework for the categorical data case is given in the form of concluding remarks.     

Common ownership and competition in product markets

We investigate the relation between common institutional ownership of the firms in an industry and product market competition. We find that common ownership is neither robustly positively related with industry profitability or output prices nor is it robustly negatively related with measures of nonprice competition, as would be expected if common ownership reduces competition. This conclusion holds regardless of industry classification choice, common ownership measure, profitability measure, nonprice competition proxy, or model specification. Our point estimates are close to zero with tight bounds, rejecting even modestly sized economic effects. We conclude that antitrust restrictions seeking to limit intra-industry common ownership are not currently warranted.     

Business process re-engineering: experiences in R&D

This study presents information drawn from leading transnational organizations headquartered in the US that are, to different degrees, involved in restructuring their R&D. Interviews were conducted with three companies in the chemical/pharmaceutical industry and three in electronics/information technology. All companies interviewed agreed on the need to organize their R&D more effectively in order to meet consumer demands and respond to competitive pressure. There are significant differences in the extent to which each company is involved in organizational change as well as their approach to such changes. The interview findings indicate that global re-engineering and business transformation programmes are being carried out. We identify the application of such approachs, men though thg may be initiated under other names.     

IN SEARCH OF EXCELLENT MANAGEMENT

Despite important advances in recent years, no agreement exists concerning what constitutes management excellence. Specific knowledge of how managerial behaviour is perceived and evaluated by others will help to resolve unsettled questions about what is meant by management excellence and improve the actual decisions of managers. This article examines the determinants of managerial excellence as perceived by corporate CEOs, directors, and financial analysts in Fortune magazine's annual survey of the best-managed American firms in 33 industries. While the firms perceived to be best managed are more profitable and less risky, and grow faster and reward their stockholders more than less well-managed firms, these variables explain only about 30 per cent of the variance in management ratings. the firms perceived to be best managed have more involvement in international markets and research and development, while large firm size and firm diversification reflect negatively upon perceived managerial quality. the relative inability of conventional financial measures of firm performance to explain perceptions of managerial excellence underlines the complex nature both of these perceptions and strategic behaviour. the results support Varadarajan and Ramanujam's conclusion that excellent management depends upon a diverse set of competencies and values, as well as Chakravarthy's contention that the most important characteristic of firm performance is management's ability to transform the firm and adapt to a rapidly changing environment. By contrast, little support is found for the maximization of stockholder wealth criterion of Rappaport.
