In the context of Europeanization, transnational LGBTI rights and politics discourses and paradigms interact with local ones. However, the effects of this interaction on trans* people in the margins of ‘Europe’ have received little attention. Drawing from participant observation and interviews with trans* respondents, I examine how trans* subjectivities and politics in Cyprus are shaped amidst this process. I show that institutional responses to trans* claims reinforce trans* marginalization. I find that trans* people are marginalized in, and disappointed by the normalization of, the (trans)national LGBTI movement. I argue that these factors induce alternative modes of everyday trans* politics and community organizing outside NGO structures. Therefore, this article helps decentre trans* studies’ typical focus on Western Europe, North America and Australasia, while offering an analysis of the role of Europeanization in Cypriot LGBTI politics.

Students today demand that what they are taught or what they discuss is ‘socially relevant’. A topic appears to exhibit social relevance when it is related to some issue currently reckoned important and the subject of controversy. No topic at present is thought more socially relevant than the role of women in society. Extra-mural students can vote with their feet as undergraduates cannot, and it is significant how regularly the brochures of university extra-mural departments in Britain have come to feature courses with titles such as ‘Women's Studies’, ‘New Horizons for Women’, ‘Images of Women’, and ‘Women Speak’. Teachers of Classics have not been reluctant to devise their own courses on women in antiquity, and it is my impression that no university in North America is without a course of this type, while postgraduate seminars covering the same field of interest seem to have become firmly established throughout Western Europe. Books, articles, and notes on women and ancient society abound, and the resultant bibliography grows more and more daunting each year.

Abstract. The last interglacial, also known as the Eemian, is characterized by warmer than present conditions at high latitudes. This is implied by various Eemian proxy records as well as by climate model simulations, though the models mostly underestimate the warming with respect to proxies. Simulations of Eemian surface air temperatures (SAT) in the Northern Hemisphere extratropics further show large variations between different climate models, and it has been hypothesized that this model spread relates to diverse representations of the Eemian sea ice cover. Here we use versions 3 and 4 of the Community Climate System Model (CCSM3 and CCSM4) to highlight the crucial role of sea ice and sea surface temperatures changes for the Eemian climate, in particular in the North Atlantic sector and in Greenland. A substantial reduction in sea ice cover results in an amplified atmospheric warming and thus a better agreement with Eemian proxy records. Sensitivity experiments with idealized lower boundary conditions reveal that warming over Greenland is mostly due to a sea ice retreat in the Nordic Seas. In contrast, sea ice changes in the Labrador Sea have a limited local impact. Changes in sea ice cover in either region are transferred to the overlying atmosphere through anomalous surface energy fluxes. The large-scale spread of the warming resulting from a Nordic Seas sea ice retreat is mostly explained by anomalous heat advection rather than by radiation or condensation processes. In addition, the sea ice perturbations lead to changes in the hydrological cycle. Our results consequently imply that both temperature and snow accumulation records from Greenland ice cores are sensitive to sea ice changes in the Nordic Seas but insensitive to sea ice changes in the Labrador Sea. Moreover, the simulations suggest that the uncertainty in the Eemian sea ice cover accounts for 1.6 °C of the Eemian warming at the NEEM ice core site. The estimated Eemian warming of 5 °C above present day based on the NEEM δ15N record can be reconstructed by the CCSM4 model for the scenario of a substantial sea ice retreat in the Nordic Seas combined with a reduced Greenland ice sheet.

This chapter explains how informal organizations are conceptualized in the book. It also maps temporal and geographic trends. It starts by explaining the idea of a formal international organization and uses this idea as a model to illustrate the contrasting features of informal organizations. The chapter then reviews what are called the distinct “functional properties” and “domestic implications” of formal and informal organizations, which are central for understanding the different theories that have been offered. The final part of the chapter explains how the concept of an informal organization has been operationalized and used to generate a database of informal institutions. Descriptive statistics are presented that help scholars to visualize the institutional terrain any theory of informality must explain. These reveal the extraordinary growth of informal organizations since the end of World War II, as well as the central role of states in North America and Western Europe in that growth.

Abstract. The last interglacial, the Eemian, is characterized by warmer than present conditions at high latitudes and is therefore often considered as a possible analogue for the climate in the near future. Simulations of Eemian surface air temperatures (SAT) in the Northern Hemisphere, however, show large variations between different climate models and it has been hypothesized that this model spread relates to diverse representations of the Eemian sea ice cover. Here we use versions 3 and 4 of the Community Climate System Model (CCSM3 and CCSM4), to highlight the crucial role of sea ice and sea surface temperatures during the Eemian, in particular for SAT in the North Atlantic sector and in Greenland. A substantial reduction in sea ice cover results in an amplified atmospheric warming and, thus, a better agreement with Eemian proxy records. Sensitivity experiments with idealized lower boundary conditions reveal that warming over Greenland is mostly due to a sea ice retreat in the Nordic Seas. In contrast, sea ice changes in the Labrador Sea have a limited local impact. Changes in sea ice cover in either region are transferred to the overlying atmosphere through anomalous surface energy fluxes. The large-scale warming simulated for the sea ice retreat in the Nordic Seas further relates to anomalous heat advection. Diabatic processes play a secondary role, yet distinct changes in the hydrological cycle are possible. Our results imply that temperature and accumulation records from Greenland ice cores are sensitive to sea ice changes in the Nordic Seas but insensitive to sea ice changes in the Labrador Sea. Moreover, our simulations suggest that the uncertainty in the Eemian sea ice cover accounts for 1.6 °C of the Eemian warming at the NEEM ice core site. The estimated Eemian warming of 5 °C above present-day based on the NEEM δ15N record can be reconstructed by the CCSM4 model for the scenario of a substantial sea ice retreat in the Nordic Seas combined with a reduced Greenland ice sheet.

Studies on ethnic entrepreneurship may be reaching a turning point. This is indicated by the high number of reviews of the literature published in the last few years (Barrett, Jones, and McEvoy; Chan and Ong; Rath, “Introduction”; Rath and Kloosterman). There seems to be a felt need for recapitulations of thirty years of fruitful and dynamic research on the topic. Three or four decades ago, there was no such thing as an “ethnic economy”: as a fact, it barely existed; as a concept, the role of ethnicity in contemporary economic life was largely unexplored. The appearance and growth of ethnic businesses, both in North America and in Western Europe, was followed by a large body of research that is today mature and important enough to be surveyed and evaluated, as in this volume, which can also function as an advanced textbook for new researchers.

Based on the observation that a rising number of scholars and students with Muslim background study and teach Islamic studies in Western Europe and North America, we propose the following two broad hypotheses: 1) that this development within academia will bring about changes within the narrow confines of Academia, but 2) will also have wider implications for the development and formation of Islamic thinking/exegesis in Western Europe and North America and perhaps even core-Islamic countries in the Middle East and South East Asia. In order to understand and assess this new state of affairs and its prospects, we set out to identify and analyse the social, religious, national background and role of these new academic stakeholders, their relevant institutions, programmes, research themes and approaches, challenges and opportunities. Based on the premise that Islam is a religion with strong scripturalist roots (among other roots to be sure) we direct particular attention to that field within Islamic studies that deals specifically with Qur’an and hadîth-related studies. This research project, then, investigates two questions. The first one is the most restricted and relates to organizational matters of the contemporary university (human resources, curriculum, funding etc.) and the Forschungsgeschichte and prospects of Islamic/Qur’ânic studies. The second question is more extensive in scope and probes grand-scale theological-exegetical trends, profiles and scenarios of a so-called Western Islam.
