Mean-value identities as an opportunity for Monte Carlo error reduction

In the Monte Carlo simulation of both lattice field theories and of models of statistical mechanics, identities verified by exact mean values, such as Schwinger-Dyson equations, Guerra relations, Callen identities, etc., provide well-known and sensitive tests of thermalization bias as well as checks of pseudo-random-number generators. We point out that they can be further exploited as control variates to reduce statistical errors. The strategy is general, very simple, and almost costless in CPU time. The method is demonstrated in the twodimensional Ising model at criticality, where the CPU gain factor lies between 2 and 4.

Performing the personal within the organizational: Communicating professional identities through Taiwanese commercial airline pilots' personal narratives

This dissertation project explored professionalism and the performance of identities by examining Taiwanese commercial airline pilots' discursive practices in everyday life. The intentions for this project were to not only expand current knowledge of organizational communication from a critical rhetorical perspective, but to further explore the under-appreciated concept of professionalism of organizational members. Theoretically, I traced theoretical analysis in the sociology of professions and further investigated scholarship from identity research in organizational communication studies. This research agenda helped to advance communication-based understandings of the meanings and practices of professional identity as a complement to the sociological conception. I further merged a performance paradigm and critical rhetorical perspective to examine the discursive practices of organizational members and to challenge the bias of traditional textual approaches. Methodologically, I conducted ethnographic interviews with Taiwanese commercial airline pilots in order to understand how they construct their personal, social, and professional identities. Five narrative themes were identified and demonstrated in this project: (1) It takes a lot to become a commercial airline pilot, (2) Being a professional commercial airline pilot is to build up sufficient knowledge, beyond average skill, and correct attitude, (3) Pilots' resistance and dissent toward company management, (4) Popular (re)presentation influences professionalism, (5) Power and fear affect professionalism. Pilots' personal narratives were presented in performative writing and in poetic transcription to make word alive with sounds featuring their meanings. Their personal storytelling created a dialogic space to not only let pilots' voice to be heard but also revealed how identities are created within and against a larger organizational identity. Overall, this project demonstrated the interdisciplinary examination of the meanings, functions, and consequence of discursive practices in everyday professional life. It also critiqued relationships between power, domination, and resistance while reintroducing the roles of the body and materiality in the domain of professionalism, and provides ethical readings of larger and complex organizational cultures. Applying communication-oriented analysis to study professionalism indeed challenged the long time neglected phenomena regarding the power of the symbolic in sociological approaches and raised the awareness of structural, material, and bodily condition of work.

The Hybrid Spirit Animating Chinese Pentecostals in Malaysia

This dissertation interrogates the assertion in postcolonial scholarship, especially from the work of Homi Bhabha that the construction and performance of hybrid identities act as a form of resistance for marginalized communities against structures of oppression. While this study supports this assertion, it also critiques how hybridity fails to address issues of unequal power relations. This has led to an uncritical use of hybridity that reproduces the very idea of static identity which its proponents claim to transcend. Through qualitative study of Chinese members of a Pentecostal church in Malaysia, this study argues that church members engage in "unequal belonging" where they privilege certain elements of their identities over others. In concert with Pierre Bourdieu's conceptions of habitus, field, and capital, unequal belonging highlights how hybridity fails to capture the intersecting and competing loyalties, strategies, and complexities of identity formation on a contextual level. Unequal belonging challenges postcolonial scholars to locate the subtle workings of power and privilege that manifest even among marginalized communities. The study first situates the Chinese through an analysis of the historical legacy of British colonialism that has structured the country's current socio-political configuration along bounded categories of identification. The habitus constrains church members to accept certain Chinese ethnic markers as "givens." Although they face continuous marginalization, interviewee data demonstrates that church members negotiate their Chineseness and construct a "Modern Chinese" ethnic identity as a strategic move away from Chinese stereotypes. Moreover, conversion to Christianity affords church members access to cultural capital. Yet, it is limited and unequal capital. In particular, the "Chinese Chinese," who church members have demarcated as backward and traditional, are unable to gain access to this capital because they lack fluency in English and knowledge in modern, westernized worldviews. Unequal belonging nuances monolithic conceptions of hybridity. It demonstrates how church members' privilege of Christianity over Chineseness exposes the complex processes of power and privilege that makes westernized-English-speaking Chinese Christians culturally "higher" than non-English-speaking, non-Christian, Chinese. This study provides significant contribution to the complex aspect of hybridity where it is both a site of resistance and oppression.

Agora nós somos camponeses! A territorialização dos camponeses pomeranos e o monumento natural dos pontões capixabas

A presente tese tem como objetivo analisar territorialização dos descendentes pomeranos na região de Pancas/ES e o processo de recriação/resignficação de sua identidade étnica e social e de seu modo de vida. Entende-se o território como um espaço constituído a partir de relações sociais desenvolvidas ao longo do tempo e, portanto, repleto das relações contraditórias do modo de produção capitalista, como o campesinato, que tende tanto à sua destruição como também necessita de relações não capitalistas em sua lógica, possibilitanto assim, sua recriação. A comunidade de camponeses pomeranos se territorializou na área onde se localizam os Pontões Capixabas a partir de 1918, mas, desde o ano de 2002 passou a viver uma situação de conflito fundiário, pois suas terras (colônias) estavam sob ameaça de desapropriação, colocandoos em uma disputa territorial na tentativa de barrar a possível expropriação das terras e consequentemente do seu modo de vida tradicional frente à implantação de uma Unidade de Conservação Ambiental de Proteção Integral. Neste contexto de conflito, a consciência de classe se faz presente com mais força, levando ao fazer-se dessa classe social, que entendia já ter conquistado a terra de trabalho. O território é fator fundante para a recuperação e afirmação da identidade étnica e social dos imigrantes pomeranos, identidade esta perdida não só com o fim da Pomerânia enquanto nação, mas por todo o processo de expropriação e dominação que sofreram ao longo do tempo, e, recuperada com a territorialização, pois, o acesso à terra de trabalho possibilitou a continuidade de seu modo de vida, mas principalmente a manutenção da língua tradicional e a recriação enquanto camponês e pomerano.

Ethnic Violence on Kenya's Periphery: Informal Institutions and Local Resilience in Conflict-Affected Communities

Deadly, inter-ethnic group conflict remains a threat to international security in a world where the majority of armed violence occurs not only within states but in the most ungoverned areas within states. Conflicts that occur between groups living in largely ungoverned areas often become deeply protracted and are difficult to resolve when the state is weak and harsh environmental conditions place human security increasingly under threat. However, even under these conditions, why do some local conflicts between ethnic groups escalate, whereas others do not? To analyze this puzzle, the dissertation employs comparative methods to investigate the conditions under which violence erupts or stops and armed actors choose to preserve peace. The project draws upon qualitative data derived from semi-structured interviews, focus group dialogues, and participant observation of local peace processes during field research conducted in six conflict-affected counties in Northern Kenya. Comparative analysis of fifteen conflict episodes with variable outcomes reveals the conditions under which coalitions of civic associations, including local peace committees, faith-based organizations, and councils of elders, inter alia, enhance informal institutional arrangements that contain escalation. Violence is less likely to escalate in communities where cohesive coalitions provide platforms for threat-monitoring, informal pact making, and enforcement of traditional codes of restitution. However, key scope conditions affect whether or not informal organizational structures are capable of containing escalation. In particular, symbolic acts of violence and the use of indiscriminant force by police and military actors commonly undermine local efforts to contain conflict. The dissertation contributes to the literatures on civil society and peacebuilding, demonstrating the importance of comparing processes of escalation and non-escalation and accounting for interactive effects between modes of state and non-state response to local, inter-ethnic group conflict.

Broadening the Scope of Ethnic Identity: A Social Sustainability Solution for Pan African Communities through Ethnically Relevant Educational Programming

This conceptual study explores ethnic identity development theory in order to argue that ethnic identity development education is a means of developing broad senses of community in the African Diaspora that expand beyond a tribal, local, familial level. This study suggests that the broadening of community understanding would contribute to establishing social sustainability on regional, national and international levels within the Pan African community. Establishing such social sustainability would have direct effects on the areas of economic and environmental sustainability. One of the goals of this project is to offer suggestions for ethnically relevant education that can develop social sustainability in several places throughout the Diaspora, such as in Nigeria where ethnic conflicts are a contemporary concern.

The Role of Education and Government in Shaping Muslim Women's Rights: Three Contemporary Case Studies

The rise in Muslim terrorist activities has encouraged the West to reevaluate its understanding of Islam, prompting concern for Muslim women's rights. In search of education-based solutions, this project explores three case studies of Muslims living under different government types: a secular state with a primarily Muslim population (Turkey); a secular state with a significant Muslim minority population (France); and a Muslim state with a powerful religious influence (Afghanistan). The type of government plays a significant role in Muslim women's rights, and solutions must be based on individual aspects of each unique place where Muslims live today. The results show that education is a universal solution when accepted at all levels: governmental, communal, and the individual.

Visions of the Spanish Revolution: identities and conflicts in post-welfare societies

This is a case study that analyzes photographic documents of the social protest in Spain between 2011 and 2013. The analysis is qualitative and considers the use of space, the visual expression of the messages and the orientation toward the causes or effects of political, economic and social changes. Visual sociology allows us to appreciate, in the case of the Spanish Revolution, a dynamic of “reflexivity” unrecognizable from other research approaches. Two successive waves of social mobilization in response to two different shocks can be appreciated. The first is given by political corruption, unemployment and the threat to consumer society. The second shock is caused by the savage cuts in the Welfare State. Social mobilization is expressed differently in each phase, and the forms taken by the protests show how the class structure in post industrial society shapes the reactions to the crisis of the Welfare State.

Ultrathin high-index metasurfaces for shaping focused beams

The volume size of a converging wave, which plays a relevant role in image resolution, is governed by the wavelength of the radiation and the numerical aperture (NA) of the wavefront. We designed an ultrathin (λ/8 width) curved metasurface that is able to transform a focused field into a high-NA optical architecture, thus boosting the transverse and (mainly) on-axis resolution. The elements of the metasurface are metal-insulator subwavelength gratings exhibiting extreme anisotropy with ultrahigh index of refraction for TM polarization. Our results can be applied to nanolithography and optical microscopy.

Redrawing Identity Boundaries through Integration Policies: Strategies of Inclusion/Exclusion of Immigrants in Québec and South Tyrol. EDAP Paper 01/2013

Following the research agenda introduced by Will Kymlicka, this qualitative study offers an interpretation of how the sub-national elites of Québec and South Tyrol police the integration of immigrants. For these national minority groups, which are constantly undergoing a process of redefinition of their collective identities by differentiating themselves from the Others who do not belong to the in-group, immigrants have progressively become the most significant Others as they are not part of the original system of compromises. This article questions how sub-national elites are handling this relatively new kind of ethnocultural diversity brought about by large-scale permanent immigration on two levels: first, the political narrative of the ruling sub-national parties, their electoral appeals, manifestos and speeches; second, the policy arrangements for the integration of immigrants in education, language and social policy. The initial approach of the article is pessimistic, as it assumes that sub-national elites will marginalize immigrants to please core nationalist supporters. In fact, the hypotheses to be tested are whether the national minority groups of Québec and South Tyrol engage in a process of reconstruction of their ethnic identity bounded by opposition to real or imagined Others – the newcomers; and whether they adopt practical measures that force newcomers to be assimilated into the group or to be marginalized. The comparison between Québec and South Tyrol provides a basic understanding of the impact of immigration in two sub-national polities that are very different, but still adopt similar political narratives and policy strategies with regard to the integration of newcomers.

Legal shifts : shaping expectations of intellectual property protection in an open innovation industrial environment

Projet de recherche réalisé en 2014-2015 avec l'appui du Fonds de recherche du Québec – Société et culture.

"Viewers should not try this at home". Die Verfassungsgerichte Bosnien-Herzegowinas und Kosovos in deren Rolle als Schlichtungsinstanzen in ethnopolitischen Konflikten = The constitutional courts of Bosnia-Herzegovina and Kosovo in their role as arbitration bodies in ethno-political conflicts. EDAP 01/2014

The article analyzes the role of constitutional courts in Bosnia and Kosovo, both characterized by their partly internationalized membership, in the adjudication of cases that are highly controversial between the different ethno-political factions. The main focus is on the Constitutional Court of Bosnia, which presents one of the richest and most interesting examples of “lawfare” in divided societies. The concept of lawfare has been adapted to refer to the continuation of political battles by ethno-political actors through legal means, in this case, constitutional adjudication. In Kosovo, the Constitutional Court has been an important defender of diversity, albeit its primary focus and merit are to have contributed to the establishment of a concept of democracy close to the people of Kosovo. The article concludes that constitutional courts represent important institutions of internal conflict resolution in divided societies, which have been instrumental in shaping multiculturalism in these post-conflict societies divided by deep ethnic cleavages.
