Two-sided Bayesian and frequentist tolerance intervals: general asymptotic results with applications

It is well known that that the construction of two-sided tolerance intervals is far more challenging than that of their one-sided counterparts. In a general framework of parametric models, we derive asymptotic results leading to explicit formulae for two-sided Bayesian and frequentist tolerance intervals. In the process, probability matching priors for such intervals are characterized and their role in finding frequentist tolerance intervals via a Bayesian route is indicated. Furthermore, in situations where matching priors are hard to obtain, we develop purely frequentist tolerance intervals as well. The findings are applied to real data. Simulation studies are seen to lend support to the asymptotic results in finite samples.

“A bulletin board of dreams”: corporate empowerment promotion and feminist implications

This article examines the premises of corporate solutions to gender inequality in the Global South. In feminist debates, businesses’ increasing emphasis on women’s empowerment has been discussed both in terms of increasing feminist impact and the co-optation of feminist demands. To explore the ideological effects of corporate gender practices, focus is placed on the Coca-Cola Company’s global “5by20” campaign, which has the stated aim to empower five million women as small-scale entrepreneurs around the world and, in a “win–win” fashion, to double sales by 2020. Based on interviews and participatory observations in Mexico, this article traces a particular narrative of empowerment, envisioned as a transition from dependency to self-sufficiency and threatened by psychological and cultural restraints rather than material conditions. It shows that self-help and positive thinking are essential affective drives, thus reinforcing market-based, individualized development strategies. In response to feminist debates, the article concludes that corporate gender practices can be seen as part of a neoliberal transposition of equality concerns from a political to an economic domain. In effect, when initiatives such as 5by20 promote the accumulation of “human capital” to enhance gender equality, they simultaneously work to legitimize the inequalities that are necessarily entailed in competitive capitalism.

A New Pearson-Type QMLE for Conditionally Heteroscedastic Models

This article proposes a novel Pearson-type quasi-maximum likelihood estimator (QMLE) of GARCH(p, q) models. Unlike the existing Gaussian QMLE, Laplacian QMLE, generalized non-Gaussian QMLE, or LAD estimator, our Pearsonian QMLE (PQMLE) captures not just the heavy-tailed but also the skewed innovations. Under strict stationarity and some weak moment conditions, the strong consistency and asymptotic normality of the PQMLE are obtained. With no further efforts, the PQMLE can be applied to other conditionally heteroscedastic models. A simulation study is carried out to assess the performance of the PQMLE. Two applications to four major stock indexes and two exchange rates further highlight the importance of our new method. Heavy-tailed and skewed innovations are often observed together in practice, and the PQMLE now gives us a systematic way to capture these two coexisting features.

Migration as a window to empowerment: Nepalese women's experiences in South Korea

ABSTRACT

Migrant women are often described as victims of the global economy: accounts of human rights abuses and economic exploitation have eclipsed more positive accounts of the impact of migrant work on women's lives. Some migrant women are positioned to make use of new opportunities which they see as empowering, in contrast to earlier experiences in their homes or sending countries. This study, based on qualitative interviews with 13 young Nepalese women working in manufacturing and agricultural sectors with Employment Permits in South Korea, highlights a rather positive window of women's empowerment. It shares the perspectives of young, mostly single women who gain self-confidence through their new ability to take care of their family (some becoming primary breadwinners). The women are also able to plan for their economic futures, and report their voices being heard more in important family decision-making. These material, relational, and perceptual improvements are all important dimensions of empowerment. In these experiences, gender intersects with age and other factors to produce a nuanced view of specific young women's experience of migrant work.     

Unthinking the European Higher Education Area – differentiated integration and Bologna's different configurations

Differentiated integration was conceived of as a political methodology and as a technology to achieve a European “union” in the field of knowledge policies. However, the non-achievement with regard to the political goals of the European Higher Education Area has highlighted the limitations of this approach to promote furthering the EHEA. In this paper, unthinking is both a research strategy aiming to question those limits and a pedagogical tactic to question the assumptions about the futures. As a research strategy, articulations between unity and diversity are examined. Based on the analysis of the documents endorsed by the Education Ministers in keeping the pace of the Bologna process, the paper contributes to expand knowledge on the nature of Bologna’s differences and underlines the paradoxes in dealing with those differences. As a pedagogical tactic, unthinking questions the assumptions about the future scenarios sketched for higher education. Alternative ways to further integration are discussed on the basis of the idea of integration of the “differences”, bringing to the centre education as a political concern, as higher education institutions, professors, and students/graduates are those at the core of the political management of the “differences”.     

Breaking the Walls. The Representation of Domestic Space in Hungarian Panel-Films

The paper investigates how socialist architecture – both as location and visual text – functions as tool of political criticism in the late socialist cinema of Hungary. Through the textual analysis of the living space in the socialist bloc in Péter Bacsó’s A Pianino in Mid-Air (Zongora a levego”ben, 1976), Béla Tarr’s Family Nest (Családi tu”zfészek, 1977) and Prefab People (Panelkapcsolat, 1982), Péter Gothár’s A Priceless Day (Ajándék ez a nap, 1979) and György Szomjas’s Wall Driller (Falfúró, 1985), the study dwells on the elimination of domestic space in the films which, as argued below, corresponds to the families’ disintegration and so to the failure a coherent, socialist society.
