Tukey’s M-estimator of the Poisson parameter with a special focus on small means

We treat robust M-estimators for independent and identically distributed Poisson data. We introduce modified Tukey M-estimators with bias correction and compare them to M-estimators based on the Huber function as well as to weighted likelihood and other estimators by simulation in case of clean data and data with outliers. In particular, we investigate the problem of combining robustness and high efficiencies at small Poisson means caused by the strong asymmetry of such Poisson distributions and propose a further estimator based on adaptive trimming. The advantages of the constructed estimators are illustrated by an application to smoothing count data with a time varying mean and level shifts.     

State standards for domestic violence perpetrator treatment: current status, trends, and recommendations

We empirically surveyed and analyzed existing standards for the treatment of perpetrators of domestic violence across the United States. Specific areas examined included: presence and scope; administrative entity for certifying; screening and risk assessment protocols; minimum length of treatment; theoretical or conceptual orientation; treatment content; preferred or allowable modalities of treatment; whether research findings are mentioned; methods for revising standards; and minimum education and training required for providers. We examined trends using several methods including comparisons between present and previous survey data (Maiuro et al., 2001). Positive trends were evident including increased use of multivariate models of treatment content, use of an intake assessment prior to treatment, use of a danger/lethality assessment to manage risk, recognition of the need for program evaluation and supportive research, and the requirement of a minimum level of formal education as a prerequisite for providers. We identify specific areas for further research and development and make recommendations for improving existing practice and standards of care.     

PRODUCT DIVERSITY,DEMAND STRUCTURES,AND OPTIMAL TAXATION

This article studies optimal taxation in a general equilibrium macroeconomic model with endogenous entry. We compare the constant elasticity of substitution (CES) model to three alternative demand structures: oligopolistic competition in prices, oligopolistic competition in quantities, and translog preferences. Our economy is characterized by two distortions: a labor distortion due to the misalignment of markups on goods and leisure, and an entry distortion due to the misalignment of the consumer surplus effect and the profit destruction effect of entry. The two distortions interact in determining the wedge between the market‐driven and optimal level of product diversity. We show how optimal labor and entry taxes depend on the prevailing demand structure, the nature and size of entry costs, and the degree of substitutability between goods. (JEL E22, E61, E62)     

Marxistische Theoriearbeit in der Krise

The economic as well as political and ideological crises and transformations of capitalist social formations have created a crisis for Marxist approaches. This affects their assumption about the necessity, desirability and possibility of social transformation, but also about the actors fighting them out and their activities. Thus, a far reaching reformulation of its fundamental epistemological and theoretical assumptions is necessary. This contribution argues that the crisis of Marxism demands a self-reflective engagement with conditions of Marxist theoretical work. The acknowledgement of the fundamental openness and incompleteness of Marxist social critique as well as its contested production is indispensable to avoid authoritarian forms of politics and to be implicated into the legitimation of domination again. The encompassing character of the crisis tendencies of capitalist social formations and the multiplication of fields of conflict demands to overcome a monistic interpretation of social dynamics. To conceptualise capitalist social formations as relation of relations is an indispensable precondition for the analysis of the connections between different social structures and relations of power and dominance. Furthermore, the ability of capitalist social formations to change, which has been shown by the recent crises and transformations, demands a fundamental dynamisation of the Marxist concept of reproduction. The dynamisation of relative surplus production in knowledge based capitalism moves the adaptability of the subjects and their capacity to work centre stage. Only against this background can the plurality of perspectives for emancipation and social struggles come into view for Marxist theoretical work.     

Application of Social Science Knowledge to the Community Organization Field

Community organization graduates of the School of Social Work, University of Washington, from 1966 to 1971, found a ready market for their skills although there was evidence of some slackening of demand and broader diversification of initial employment settings in the last two years. Graduates moved rapidly into administrative and management levels and appeared relatively stable in terms of interagency and geographical mobility. The small number of ethnically identified graduates made meaningful comparisons difficult. Sex, however, was a disadvantaging factor in employability and subsequent status. Of the ninety-one graduates surveyed, 94.5 percent responded Similar follow-up study of graduates in other geographic regions was recommended     

French and British Top Managers' Understanding of the Structure and the Dynamics of Their Industries: a Cognitive Analysis and Comparison

This paper presents the findings of an exploratory study of the content of and differences between managerial frames of references with regard to the structure and dynamics of competitive environments. These frames of references are examined and compared at both the industry level and the country level; and the paper shows the influences of both industry and institutional structures and national culture on managerial thinking. It therefore contributes to the field of comparative management, as well as the growing interest in cognitive analysis in the field of management. The study is particularly significant since (a) its context is the rapidly changing industry environment of Europe, and (b) the managers are all involved in the development of strategies for their firms. Thirty three top managers (16 English and 17 French) were interviewed in four industries (brewing, car manufacturing, retail banking and book publishing) on their understanding of their industry and the strategy of their company. Content analysis of the transcribed interviews surfaces cognitive constructs which facilitate the identification of similarities and differences between managers, (a) within industries, (b) across industries, (c) within countries, (d) between countries and (e) between countries within the different industries. The analysis also provides means whereby the constructs can be represented in the form of cognitive maps.     

Finding your way into employment against all odds? Successful job search of refugees in Austria

Labour market entry poses enormous challenges for recently arrived refugees, ranging from language barriers, devaluation of human capital, unfamiliarity with customs of the job search process to outright discrimination. How can refugees overcome these challenges and quickly enter gainful employment? In this paper, we draw on interviews with 26 male and female refugees from Syria, Afghanistan, Iraq and Iran, conducted in 2017 and 2018, who came to Austria in 2015 and 2014 and who have successfully entered employment. We depict refugees’ own perspectives on and strategies for fast job entry and integration. Personal agency and a proactive approach of seeking and seizing opportunities are key for overcoming initial barriers and entering upon positive integration pathways. At the same time, refugees’ personal agency is essential for establishing social ties to the host society, which also play a crucial role in early labour market integration. Finally, institutions of the Austrian labour market (the ‘apprenticeship’-system) interact with refugees’ agency in most intricate ways, both setting up nearly insurmountable barriers but also providing specific opportunities for refugees.
