Stability of environment and of insect populations

Summary The abundance of moths was monitored with light-traps in two sites in southern Bohemia, České Budějovice for 22 years and in Černiš for 9 years. In these sites, that are vastly different in environmental stability and predictability, stability of insect populations was studied. The amplitude of fluctuations in abundance of the insect populations, as measured by the coefficient of variation (CV), varied a great deal between species so that there was a large overlap between the two sites. Nevertheless there was a highly significant tendency for species at Černiš, the more stable site, to have smaller values of CV, i.e., to be less fluctuating. Also in species co-occurring in the two sites, the CV at Černiš tended to be smaller. Trends in abundance of individual species over time, both increases and decreases, were common in both sites and did not differ between habitats. Environmental stability begets insect population stability in terms of the amplitude of the fluctuations, but trends in time occur irrespective of stability of the habitat.     

Managers' Perceptions of their Identity: A Comparative Study between the Czech Republic and Britain

After a period of more that 40 years of Communism, the Czech Republic is in the midst of an economic transformation. One aspect of this transformation is the development of a new managerial ethos, important to manage the current infrastructural changes and ensure that Czech organizations are able to compete in international markets.
This paper reports research that examines what Czech managers think about themselves and their roles, and contrasts these perceptions with those of their British counterparts. Many of the concepts and development approaches being applied in the Czech Republic are closely related to concepts and development approaches in the West and have often been accepted unchallenged even though they are being applied in very different circumstances. The focus of this research was to understand how Czech and British managers view their jobs; how their different views relate to the techniques and approaches they adopt. The method chosen was discourse analysis applied to responses from a questionnaire, interviews and repertory grid technique. Using this approach a very different kind of understanding was gained in the way Czech managers think about management than has hitherto been assumed.
The research takes a matched group of Czech and British managers and contrasts their respective views. Our findings give important new insights for management and management development practice for both the Czech Republic and Great Britain.     

Technical progress and the work force in Czechoslovakia

The authors analyse likely changes in the structure of education and qualifications in the Czechoslovak work force during the next thirty years. They stress the low level of qualification, particularly among management, compared with other industrialized countries, and the impact that this is probably having on productivity and on exports. Over the next thirty years, they foresee increasing mechanization in agriculture and forestry, more mechanization and automation in industry, and in certain types of services, and in consequence, a large increase in demand for qualified personnel, especially scientists and technologists.     

Economic and Institutional Context and Second Births in Seven European Countries

The extent to which mothers progress to a second child varies greatly between European countries. Although both institutional and economic context are believed to be partly responsible for these differences, available research on economic conditions and fertility mostly focuses on first births and studies on family policy and fertility have hitherto insufficiently addressed population heterogeneity. Combining longitudinal microdata from the Harmonized Histories with contextual data on labour market uncertainty and family policy, this paper uses discrete-time hazard models to analyse the impact of economic and institutional context on second birth hazards of 22,298 women in 7 European countries between 1970 and 2002. Particular attention is paid to variation in the contextual effects by level of education. We find that aggregate-level unemployment and temporary employment reduce second birth hazards, particularly for low- and medium-level educated women. Family policies are positively related to second birth hazards. Whereas family allowances stimulate second births particularly among low educated mothers, the positive effect of childcare is invariant by level of education.     

The Scope for Fiscal Policy: A Case Study of Thailand

This article is concerned with the application of fiscal policy instruments in stabilisation policy. Theoretical and practical considerations suggest that the scope for fiscal policy may be limited, but analysis of the actual performance of Thailand shows that an active use has been made of it. Compared with advanced economies, the role of automatic stabilisers is relatively small; discretionary fiscal policy interventions have been more important. Particularly in the years after the Asian financial crisis fiscal policy has been actively used, first, under IMF programmes, to reduce aggregate demand, and later to stimulate the economy. The article focuses on the application of fiscal policy instruments, not on the impact of fiscal policy interventions on the real economy.     

Access to the labour market for gays and lesbians: Research review

ABSTRACT

This article reviews findings of scientific studies looking into the bias that gay men and lesbians face when accessing the labor market. Studies in this topic were scarce before year 2000, but a considerable body of literature appeared in the Western countries in the recent years. When summed up, the findings provide robust evidence that lesbians and gay men face negative bias when accessing employment. The magnitude of the bias varies considerably across contexts. Different labor market outcomes of gay men and lesbians are also partially caused by differences in household specialization between different-sex and same-sex households. Future research needs to address the contextual differences in bias against gay men and lesbians.     

Contextualizing ethnic educational inequality: the role of stability and quality of neighborhoods and ethnic density in second-generation attainment

This study examines the joint impact of neighborhood structure and ethnic density on the educational attainment of the second generation. Using second-generation samples and a majority reference sample from the Belgian Census, multi-level analysis yields the expected positive effects of neighborhood stability and quality and ethnic density on second-generation school completion. Reflecting the ethnic stratification of the Belgian housing market, majority residential concentration tends to coincide with high neighborhood stability and quality and high completion rates, whereas Moroccan concentrations overlap with low neighborhood quality, and low completion rates. For the Turkish and Italian second generation, neighborhood structure moderates ethnic density effects on school completion, in line with segmented assimilation. Our findings suggest distinct Moroccan, Turkish and Italian incorporation modes which reflect differential access to, and investments in ethnic versus mainstream social networks.
