If an important part of the political scientist's mission is to anticipate and explain “the critical problems that generate turbulence” in that part of the world which attracts his attention, then, in the study of administration, bureaucratic “imperialism” must be of compelling interest. If systematic data directly assembled for the purpose are lacking, and if there are some signal problems of theory which have been little investigated, there is still enough evidence from studies of other political problems that it seems worthwhile to set out some trial-run ideas in the hope that they will elicit further discussion.Bureaucractic imperialism seems pre-eminently a matter of inter-agency conflict in which two or more agencies try to assert permanent control over the same jurisdiction, or in which one agency actually seeks to take over another agency as well as the jurisdiction of that agency. We are thus primarily concerned with the politics of allocation and shall, except incidentally, bypass some other interesting aspects of inter-agency politics such as cooperation between agencies sharing missions, competition for favorable “one-time-only” decisions which do not involve jurisdictional reallocation, or the critical problems of the “holding company” administrative organization and its internal politics. For the moment, our concern with the politics of allocation leads to a focus on what would appear to be the likely behaviors of those decisionmakers who have both inclination and opportunity to look after the institutional well-being of agencies.

Abstract In this study, we identified the key mortality causes of eggs, juveniles and adults of the Great Bustard (Otis tarda) and quantified the relative importance of those, based on systematic data collection that have been carried out during the period between 2005 and 2014 at the Upper-Kiskunság region in Central Hungary. Rate of mortality regarding juveniles and adults was 39.71% caused by anthropogenic factors. Within the anthropogenic factors leading to mortality, collision was represented by 81.48% of fatalities, whereas mowing/hay making represented by 18.52%. Hay making/mowing was the factor leading to unsuccessful breeding attempt with the strongest negative effect on the breeding success of the investigated population of the Great Bustard, as it was represented by 50.96% of all known mortality cases. Chemical treatment had the factor with the second strongest effect, as it was represented by 12.33% of all known mortality cases. The rate of unsuccessful breeding (hatching) caused by particular activities (hay making/mowing, tillage, harvesting) varied between 68.42% and 75.00%. It was the disturbance by passers-by which led to the highest portion of unsuccessful breeding with 83.33% unsuccessful nests.

PurposeThe purpose of this paper is to explore the interplay between human resource management (HRM) and emergent factors in constructing a strong HRM climate. Specifically, the paper aims to shed light on how employee perceptions of the HRM process and emergent factors together construct a strong HRM climate, i.e. employees' shared perceptions of HRM.Design/methodology/approachThe paper uses qualitative interview data (managers and employees) from two organisations operating in Finland. The data are analysed based on a systematic data analysis and gives an illustration of the interplay between high-performance work system and the emergent factors.FindingsThe findings illustrate the three types of interplay between HPWS and emergent factors – supplementation, substitution and suffocation – that construct employee experience.Originality/valueThe paper extends earlier discussions on the relationship between HRM and employee experience by empirically examining how the HRM process – together with emergent factors – constructs a strong HRM climate. The present study contributes to further theorising and increasing our understanding of the creation of employee experience.

Due to the lack of systematic data collection on national and institutional levels, the higher education systems in the Western Balkans have remained under-researched. This article aims to describe and analyze some of the most salient challenges facing academic sectors in these countries, such as structural issues, growth of the private sector, and EU funding.

The organization of expert activism is a problem of increasing importance for social movement organizers and scholars alike. Yet the relative invisibility of expert activists within social movements makes them difficult to systematically identify and study. This article offers two related ways forward. First, we advance a theory of “shadow mobilization” to explain the organization of expert activism in the broader context of proliferating risk and intensifying knowledge-based conflict. Second, we introduce a new methodological approach for collecting systematic data on members of this difficult-to-reach population. Findings from comparative analysis of expert activists in the environmental justice movement in Louisiana and the alternative agriculture movement in Washington reveal both important commonalities and fine-grained differences, suggesting that shadow mobilizations are strategic collective responses to cumulative risk in contemporary society.
