The Method of Purging Applied to Repeated Cross-Sectional Data

In cross-sectional survey research, it is quite common to estimate the(standardized) effect of independent variable(s) on a dependent variable. However, if repeated cross-sectional data are available, much is to be gained if the consequences of these effects on longitudinal social change are considered.To assess these consequences, we describe a type of simulation in whichlongitudinal shifts in the independent variable's distribution, and longitudinal variation in effect on the dependent variable are `purged' from the data. Although the method of purging is known for many years, we add new practical features by relating the method to logistic and linear regression analysis. Because both logistic and linear regression analysis can be found in all majorstatistical packages, the method of purging is made available to a wider group of social scientists. With the use of repeated cross-sectional data, gathered in the Netherlands between 1970 and 1998, the new practical features of the purging method are shown, using the SPSS package.     

Comparing levels of anti-Muslim attitudes across Western countries

In this study we describe differences of the ethnic majorities?? attitudes toward Muslims across Western countries. Using data from the Pew Global Attitudes Survey (2005), we were able to increase and test cross-cultural comparability of anti-Muslim attitudes. We constructed a single factor CFA model with three indicators, which was tested for scalar equivalence. Our results indicate that anti-Muslim attitudes differ significantly across the countries in our analysis. Germany and the Netherlands turned out to display relatively high levels of anti-Muslim attitudes, whereas these levels were relatively low in Great-Britain and the USA. We conclude our study with giving some post-hoc explanations for the differences found across countries.     

The standardized effect of a compound of dummy variables or polynomial terms

A method is proposed to obtain standardized regression coefficients for composite variables made up of dummy variables or polynomial terms. The method to be described enables the researcher to compare the effect of the composite variable with the effects of other predictor variables. Forming a composite variable is particularly useful in polynomial regression where individual regression coefficients are hard to interpret. A second application is assessing the impact of a compound of dummy variables. An empirical example dealing with the curvilinear relationship between church involvement and prejudice is used to illustrate the approach.     

Structural aspects of social capital: tests for cross-national equivalence in Europe

In this contribution we start from the emerging consensus on the widely disputed phenomenon of social capital. We propose to focus on structural aspects of social capital: formal (contacts within formal organizations) and informal (contacts outside of formal organizations). First, we address methodological questions on the cross-national equivalence of these social capital measurements. Second, we re-visit substantive questions on the patterns of relationships in different European countries. In particular, we inquire to which degree formal and informal social capital can substitute each other, as well as being complementary. We take advantage of recent Eurobaromer data (2004) containing a wide range of valid measurements on both structural aspects of social capital. We find strong evidence for cross-national equivalent measurements regarding formal social capital, employing probabilistic scalogram analyses. For informal social capital, we find strong evidence for configural and metric invariance as well as evidence for partial scalar invariance, employing multi group confirmatory factor analyses. We have to reject the substantive hypothesis on substitution of formal and informal social capital for all countries under consideration, except for Romania. We corroborate the hypothesis on complementarity of formal and informal social capital.     

Aspects of the law relating to the allocation of agricultural land in Bophuthatswana

Development activities in Bophuthatswana are usually influenced by the existence of different land rights and land tenure systems. The nature of these rights are dependant on the laws which govern the allocation of different types of land and ultimately influence the utilization of land for, inter alia, specific development purposes. The allocation and utilization of land are regulated by tribal, common and statute law developed over many years. These laws are, however, often inadequate to meet the demands of well planned, integrated development strategies. Individual and national development needs, as well as official government policy, call for amendment to the existing laws relating to the allocation and utilization of especially. agricultural land. The object of this discussion is to expose some aspects of existing laws which lay down the limits within which planning and development must take place at present and further reveals efforts by the legislature to participate in planning and implementation of a more effective land use strategy, such as introduced by way of the Allocation of Agricultural Lands Acts, Act 20 of 983, as amended.     

Gaming the system: building an online management game to spread and gather insights into the dynamics of performance management systems*

ABSTRACT

Extensive research has produced many insights into the dynamics of performance management systems. Spreading these complex insights among students and practitioners can be a daunting task. Gathering new insights can be equally challenging. This article introduces a novel tool for teaching and researching performance management, reporting on the design and first use of a free online management game. Players take the role of a hospital manager trying to satisfy multiple stakeholders through applying different performance management instruments. While students learn about the complexities of performance management, researchers gather data about the pathways individuals pursue while navigating performance management systems.     

Integrating online communities within business-to-business marketing communications: an exploratory study

The article provides a conceptual contribution by developing a framework for business-to-business (B2B) marketers seeking to implement online communities (OLCs). Furthermore, the conceptual contribution is augmented by a small-scale exploratory study comprising in-depth interviews with B2B chief marketing officers (CMOs). The findings challenge existing thinking that B2B marketers can follow generic marketing communication frameworks. This is due to the differences in B2B OLCs in terms of multiple stakeholders and two-way information flows and differences in buyer behaviour. For researchers, the contribution is an embryonic model that will facilitate future conceptual development as well as empirical testing through a series of research propositions. A sequential decision-making framework, which identifies key implementation challenges, is provided for B2B managers.
