Abstract. Despite the apparent stability of the wage bargaining institutions in West Germany, aggregate union membership has been declining dramatically since the early 1990s. However, aggregate gross membership numbers do not distinguish between employment status and it is impossible to disaggregate these sufficiently. This paper uses four waves of the German Socio‐economic Panel in 1985, 1989, 1993, and 1998 to perform a panel analysis of net union membership among employees. We estimate a correlated random‐effects probit model suggested by Chamberlain (Handbook of Econometrics, Vol. II, Amsterdam: Elsevier Science, 1984) to take proper account of individual‐specific effects. Our results suggest that at the individual level the propensity to be a union member has not changed considerably over time. Thus, the aggregate decline in membership is due to composition effects. We also use the estimates to predict net union density at the industry level based on the IAB employment subsample for the time period 1985–97.  相似文献

Systems development managers today are working with increasingly complex systems, revealing a need for computer-aided techniques in software system definition, design, and construction. The ultimate task of the software engineer is the development of tools and procedures which reduce the effort involved in production of effective software. To be effective, software must possess characteristics of correctness, reliability, efficiency, documentation, and flexibility. This paper develops a measure for software effectiveness and a computer aid for determining process structure in program module specification. The proposed method uses various criteria and a mixed integer program to decompose a system graph into program modules.  相似文献

In preclinical and clinical experiments, pharmacokinetic (PK) studies are designed to analyse the evolution of drug concentration in plasma over time i.e. the PK profile. Some PK parameters are estimated in order to summarize the complete drug's kinetic profile: area under the curve (AUC), maximal concentration (C(max)), time at which the maximal concentration occurs (t(max)) and half-life time (t(1/2)).Several methods have been proposed to estimate these PK parameters. A first method relies on interpolating between observed concentrations. The interpolation method is often chosen linear. This method is simple and fast. Another method relies on compartmental modelling. In this case, nonlinear methods are used to estimate parameters of a chosen compartmental model. This method provides generally good results. However, if the data are sparse and noisy, two difficulties can arise with this method. The first one is related to the choice of the suitable compartmental model given the small number of data available in preclinical experiment for instance. Second, nonlinear methods can fail to converge. Much work has been done recently to circumvent these problems (J. Pharmacokinet. Pharmacodyn. 2007; 34:229-249, Stat. Comput., to appear, Biometrical J., to appear, ESAIM P&S 2004; 8:115-131).In this paper, we propose a Bayesian nonparametric model based on P-splines. This method provides good PK parameters estimation, whatever be the number of available observations and the level of noise in the data. Simulations show that the proposed method provides better PK parameters estimations than the interpolation method, both in terms of bias and precision. The Bayesian nonparametric method provides also better AUC and t(1/2) estimations than a correctly specified compartmental model, whereas this last method performs better in t(max) and C(max) estimations.We extend the basic model to a hierarchical one that treats the case where we have concentrations from different subjects. We are then able to get individual PK parameter estimations. Finally, with Bayesian methods, we can get easily some uncertainty measures by obtaining credibility sets for each PK parameter.  相似文献

July 28, 2019, marks the 50th anniversary of a police raid on the Stonewall Inn. During this raid, police verbally, and in some cases, physically accosted patrons of the Stonewall Inn. Events from this encounter eventually set off a series of protests by members and allies of the LGBT community. These protests came to be known as the Stonewall Riots. On June 24, 2016, the Stonewall Inn became the first U.S. National Monument dedicated to LGBT history. While this event served as a pivotal role in the gay rights movement, this article begins with an investigation into the geographical and spatial conditions surrounding the Stonewall Inn and its neighborhood. In asking, “Why New York City, why Stonewall?” we attempt to establish a cultural version of geography that uses a National Monument as a way for students to engage in the world around them through an examination of human/environment relationships. To explore this further and to celebrate Stonewall at 50, we present a pedagogical framework using articles, letters, photographs, podcasts, and Google Earth.  相似文献

We conducted a meta-synthesis review of existing literature on science, technology, engineering, and math (STEM) mentoring programs for women. Critical feminist theory (CFT) was used to understand how mentoring programs support retention and occupational advancement of women in traditionally male-dominated STEM fields. Four primary strands of CFT were explored: gender, oppression/patriarchy, social institutions, and systemic change. Traditional models of mentoring encompass varied approaches, including institutionally enforced programs, formal and informal programs, paired peer grouping, as well as face-to-face and online forums. However, low levels of retention and self-stated lack of professional satisfaction for women in STEM fields continue to plague those professions. This study reviews the literature on mentoring programs that have been implemented to support women in STEM, thus adding to the epistemology of mentoring women in STEM through feminist discourse.  相似文献

A recent exchange between Allinson (2019) and Abrams (2019) on the current state of revolution theory rests on the assumption that the generational, backward-looking view of revolution studies is also a fruitful way of thinking of the field's present and future. We argue, in contrast, that while a generational approach has important benefits, it also contains shortcomings that may lead the future of revolution studies in less fruitful directions. We examine where an overreliance on generational thinking has led us, provide an exploratory sketch of how we can begin to move beyond generational thinking, and imagine a new future for the study of revolution.  相似文献

The cosmopolitan perspective: sociology of the second age of modernity*   总被引:4,自引:0,他引:4  
'Second age of modernity' is a magical password that is meant to open the doors to new conceptual landscapes. The whole world of nation sovereignty is fading away – including the 'container theory of society' on which most of the sociology of the first age of modernity is based upon. In this article I propose a distinction between 'simple globalization' and 'reflexive cosmopolitization'. In the paradigm of the first age of modernity, simple globalization is interpreted within the territorial compass of state and politics, society and culture. This involves an additive, not substitutive, conception of globalization as indicated for example by 'interconnectedness'. In the paradigm of the second age of modernity globalization changes not only the relations between and beyond national states and societies, but also the inner quality of the social and political itself which is indicated by more or less reflexive cosmopolitization as an institutionalized learning process – and its enemies.  相似文献

This article argues that the Internet possesses the potential to challenge corporate and Statist domination of digital space. Mapping Gilles Deleuze and Felix Guattari’s concepts of the rhizome, smooth/striated space, and the nomad onto the idea of digital connectivity, I show how hacktivism can initiate change both online and off. In the first section, I argue that the Internet is characteristic of a rhizome. As a rhizome, the Internet’s structure affords it a flexible, morphological, and ultimately a vibrantly powerful configuration. As a result of its connective and generative power, corporate and State entities seek to control digital space. These controlling institutions stratify, segment, and claim ownership over the flat, smooth space. The second section, then, shows how the Internet becomes striated through corporate and State interests. As a remedy, the third section advocates for hacktivism as a form of nomadic action. In this section, I focus on the Distributed Denial of Service attack as a form of deterritorialization that redistributes the flow of information. Acting as a digital machine de guerre engaging in online direct action, and against the legal apparatus of the State, hacktivists create a rupture in the rhizomatic structure and form smooth spaces within a striated network. In the final section, I advocate for sustained smooth digital spaces that allow for new modes of association that radiate outward from the digital to the physical world.  相似文献

Islamophobia describes the racism, exploitation, and violence experienced by Arabs, individuals of Arab descent, and Muslims. Although social workers are meant to challenge social injustice, social work codes of ethics and the literature are without guidance for unlearning Islamophobia. Arguing that one’s ability to interrupt Islamophobia is strengthened by an understanding of the historical record and theoretical tenets of Orientalism, we offer social workers explicit linkages between Orientalism and Islamophobia and engage with the idea of Islamo-racism. In this article, we attend to the ways in which Orientalism is used to “other” individuals while strengthening white hegemony, and we link those processes with Islamophobia and Islamo-racism. We conclude with some strategies derived from postcolonial theory to disrupt Islamophobia.  相似文献

This article calls for a re-conceptualization of the social sciences by asking for a cosmopolitan turn. The intellectual undertaking of redefining cosmopolitanism is a trans-disciplinary one, which includes geography, anthropology, ethnology, international relations, international law, political philosophy and political theory, and now sociology and social theory. Methodological nationalism, which subsumes society under the nation-state, has until now made this task almost impossible. The alternative, a 'cosmopolitan outlook', is a contested term and project. Cosmopolitanism must not be equalized with the global (or globalization), with 'world system theory' ( Wallerstein ), with 'world polity' ( Meyer and others ), or with 'world-society' ( Luhmann ). All of those concepts presuppose basic dualisms, such as domestic/foreign or national/international, which in reality have become ambiguous. Methodological cosmopolitanism opens up new horizons by demonstrating how we can make the empirical investigation of border crossings and other transnational phenomena possible.  相似文献
