The influence of HOPE VI public housing on public schools

In the United States, public school enrollment is typically organized by neighborhood boundaries. This dissertation examines whether the federally funded HOPE VI program influenced performance in neighborhood public schools. In effect since 1992, HOPE VI has sought to revitalize distressed public housing using the New Urbanism model of mixed income communities. There are 165 such HOPE VI projects nationwide. Despite nearly two decades of the program's implementation, the literature on its connection to public school performance is thin. My dissertation aims to narrow this research gap. There are three principal research questions: (1) Following HOPE VI, was there a change in socioeconomic status (SES) in the neighborhood public school? The hypothesis is that low SES (measured as the proportion of students qualifying for the Free and Reduced Lunch Program) would reduce. (2) Following HOPE VI, did the performance of neighborhood public schools change? The hypothesis is that the school performance, measured by the proportion of 5th grade students proficient in state wide math and reading tests, would increase. (3) What factors relate to the performance of public schools in HOPE VI communities? The focus is on non-school, neighborhood factors that influence the public school performance. For answering the first two questions, I used t-tests and regression models to test the hypotheses. The analysis shows that there is no statistically significant change in SES following HOPE VI. However, there are statistically significant increases in performance for reading and math proficiency. The results are interesting in indicating that HOPE VI neighborhood improvement may have some relationship with improving school performance. To answer the third question, I conducted a case study analysis of two HOPE VI neighborhood public schools, one which improved significantly (in Philadelphia) and one which declined the most (in Washington DC). The analysis revealed three insights into neighborhood factors for improved school performance: (i) a strong local community organization; (ii) local community's commitment (including the middle income families) to send children to the public school; and (iii) ties between housing and education officials to implement the federal housing program. In essence, the study reveals how housing policy is de facto education policy.

Social-cognitive antecedents of ambidextrous orientation in family-owned startups: The role of family ties, achievement motivation, and internal locus of control

Regulatory Focus Theory predicts that the motivation to self-regulate goal-directed thought and behavior depends on two distinct regulation strategies: a promotion focus based on attaining gains and a prevention focus based on avoiding losses. This study took a social-cognitive approach predicting that regulatory focus has an impact on how family startups (several family related founders) explore "new ideas", exploit "old certainties" and achieve the balance of both (ambidexterity), compared to lone founder startups (only one founder present). It was proposed that the social context of family ties among founders leads them to a prevention focus concerned with avoiding the loss of the socio-emotional benefits of those ties. In order to avoid such a loss, family founders were expected to increase their risk perceptions and thus, explore less than lone founders, who lack such socio-emotional ties. It was also proposed that two commonly used psychological traits in entrepreneurship research —achievement motivation and internal locus of control, predispose entrepreneurs to a promotion focus. Founders with a promotion focus, in turn, were hypothesized to lead startups to more risk-seeking behaviors and to more explorative orientation. The previous argument was used as a springboard to derive hypotheses about ambidexterity (the ability to exploit and explore simultaneously) and survival hazards. Using Regulatory Focus Theory, exploitative orientation, conceptualized as the motivational strength to continue on previous paths of action, was hypothesized to be not significantly different from that of lone founder startups. Taking previous arguments together, lone founder startups were hypothesized to be more ambidextrous than family startups. Finally, ambidexterity and internal locus of control were hypothesized to reduce survival hazards in family startups. The findings suggested that family startups explore less than lone founder startups even after controlling for group effects. Interesting but contradictory findings revealed that internal locus of control have both a positive direct effect and a positive interaction that increases the explorative and ambidextrous orientation gap of family startups over lone founder startups. As expected, ambidexterity and internal locus of control reduced survival hazards on family startups. Implications for practitioners were derived based on a sample of 470 nascent entrepreneurs.

Adaptation of Trailing Spouses: Does Gender Matter?

The adaptation to a new country is a complex and stressful process that is compounded when changes in status and identity have to be made. This exploratory study examined the adaptation of international company transferee spouses when they decide to follow the transferee on overseas assignments. Research to date indicates that the spouses’ dissatisfaction with life abroad is the leading cause of transferees breaking contract and prematurely returning home. The causes of this dissatisfaction are still not clear and this study sought greater clarification, particularly examining the experiences of male as well as female trailing spouses. The study, thus, takes gender as a main variable to consider. It explores how gendered expectations inherent in the structures of society inflect and inform the decisions, attitudes, and behaviors that affect the adaptations of trailing spouses living in a foreign habitus. The study is based on eight months of ethnographic research in two culturally different locations, Kuala Lumpur, Malaysia and Brussels, Belgium. Forty-two American international company transferee spouses were recruited (seven males and thirty-five females). The data analysis revolved around five main themes: (1) the comparison of male with female trailing spouses’ experiences, (2) the effect of location on spouses’ adaptation, (3) the communities that spouses integrate into, (4) variations in personal work and family histories, and (5) conditions of exit. The analysis engaged multiple theories regarding gender, sociological adaptation, and psychological adaptation. Results indicate that both socio-cultural and psychological factors affect adaptation and that gender matters very significantly, particularly along two axes: (1) gendered structures in our society create different reasons why males and females become trailing spouses, (2) the gendered social constructions of role expectations make the experience of being a trailing husband different from being a trailing wife. In addition spouses’ status as parents (or not) and their “readiness for change” were found to be important predictors of positive spousal adaptation. In contrast, significant ties with families in the home country and strong professional identity with career projections were important predictors of negative spousal adaptation.

Strong primeness in fuzzy environment

The main aim of this investigation is to propose the notion of uniform and strong primeness in fuzzy environment. First, it is proposed and investigated the concept of fuzzy strongly prime and fuzzy uniformly strongly prime ideal. As an additional tool, the concept of t/m systems for fuzzy environment gives an alternative way to deal with primeness in fuzzy. Second, a fuzzy version of correspondence theorem and the radical of a fuzzy ideal are proposed. Finally, it is proposed a new concept of prime ideal for Quantales which enable us to deal with primeness in a noncommutative setting.

Suppression of nonlinear distortion in few-mode fibres using strong mode coupling

In this paper, we investigate the impact of linear mode coupling on the efficiency of intermodal four-wave mixing and on the group delay statistics in few-mode fibres. The investigation will include not only the weak or strong linear coupling regimes, but also the transition region between them, the intermediate coupling regime. This analysis will allow to assess the level of coupling strength require to suppress the nonlinear distortion in a few-mode fibre below the level of distortion for single-mode propagation without mode coupling.

Photocatalytic activities of tin(IV) oxide surface-modified titanium(IV) dioxide show a strong sensitivity to the TiO 2 crystal form

Surface modification of rutile TiO2 with extremely small SnO2 clusters gives rise to a great increase in its UV light activity for degradation of model organic water pollutants, while the effect is much smaller for anatase TiO2. This crystal form sensitivity is rationalized in terms of the difference in the electronic modification of TiO2 through the interfacial Sn−O−Ti bonds. The increase in the density of states near the conduction band minimum of rutile by hybridization with the SnO2 cluster levels intensifies the light absorption, but this is not seen with modified anatase. The electronic transition from the valence band to the conduction band causes the bulk-to-surface interfacial electron transfer to enhance charge separation. Further, electrons relaxed to the conduction minimum are smoothly transferred to O2 due to the action of the SnO2 species as an electron transfer promoter.

Survival of a Perverse Nation: Sexuality and Kinship in Post-Soviet Armenia

Survival of a Perverse Nation traces the ways in which contemporary Armenian anxieties are congealing into the figure of the “homosexual.” As in other post-Soviet republics, homosexuality has increasingly become defined as the crisis of the times, and is understood by many as a destructive force linked to European encroachment. In Armenia, a growing right-wing nationalist movement since 2012 has been targeting LGBT and feminist activists. I suggest that this movement has arisen out of Armenia’s concerns regarding proper social and biological reproduction in the face of high rates of emigration of especially men in search of work. Many in the country blame this emigration on a post-Soviet oligarchy, with close ties to the government. This oligarchy, having quickly and massively privatized and liquidated industry and land during the war over the region of Nagorno-Karabagh (1990-1994) with Azerbaijan, created widespread un(der)employment. A national narrative attributing the nation’s survival of the 1915 Genocide and dispersion of its populations to strong morality preserved by institutions such as the Church and the family has now, in the post-Soviet era, ruptured into one of moral “perversion.” This dissertation is based on 15 months of ethnographic research, during which I participated in the work of two local non-governmental organizations: Public Information and Need for Knowledge, an LGBT rights organization and Women’s Resource Center, a feminist organization. I also conducted interviews with 150 households across Yerevan, the capital city, and did in-depth interviews with other activists, right-wing nationalists and journalists. Through psychoanalytic frameworks, as well as studies of kinship, I show how sovereignty – the longed for dream for Armenians over the last century – is felt to have failed because of the moral corruption of the illegitimate figures that fill Armenian seats of authority. I, thus, examine the ways in which a missing father of the household is discursively linked to the lack of strong leadership by a corrupt government, producing a prevalent feeling of moral disintegration that nationalists displace onto the “homosexual.”

José Aricó y la "crisis de civilización" : La búsqueda de una imbricación democrático-socialista para un desarrollo de la "dilatación de la subjetividad" (1979-1986)

Moviéndonos entre la sociología política y la historia intelectual, abordaremos en este trabajo aspectos de la obra del "gramsciano argentino" José María Aricó (1931-1991). Con una reconocida actividad político-intelectual desarrollada en su país durante tres décadas, el golpe militar de 1976 obliga a Aricó a marchar al exilio. Anclado en México, la temática de la transición a la democracia, acuciante en distintos países de América Latina y de Europa, lo hace desembocar en una serie de estudios sobre vínculos entre la tradición democrática y la socialista, sobre la noción de progreso y sobre el preocupante divorcio que entre cultura y política se viene profundizando desde los tiempos de la Segunda Guerra Mundial. Siempre con los escritos de Gramsci latiendo en el núcleo de sus preocupaciones, Aricó regresa a la Argentina en 1983. Considerando que ni el liberalismo, ni el marxismo-leninismo, ni el populismo, ni la socialdemocracia pueden ya contribuir al montaje de un "pensamiento fuerte" de expectativas emancipatorias, profundizando además en la temática de la "dilatación de la subjetividad" y en un manejo desprejuiciado de la obra del intelectual reaccionario alemán Carl Schmitt, Aricó ensaya un recorrido inédito, estimulado por la idea-fuerza de una "democracia social avanzada", capaz de dar respuestas ambiciosas a aquello que viene señalando como una crisis de civilización.

SN 2011A: A low-luminosity interacting transient with a double plateau and strong sodium absorpton

We present optical photometry and spectroscopy of the optical transient SN 2011A. Our data span 140 days after discovery including BVRI u′g′r′i′z′ photometry and 11 epochs of optical spectroscopy. Originally classified as a type IIn supernova (SN IIn) due to the presence of narrow Hα emission, this object shows exceptional characteristics. First, the light curve shows a double plateau, a property only observed before in the impostor SN 1997bs. Second, SN 2011A has a very low luminosity (M_V=-15.72), placing it between normal luminous SNe IIn and SN impostors. Third, SN 2011A shows low velocity and high equivalent width absorption close to the sodium doublet, which increases with time and is most likely of circumstellar origin. This evolution is also accompanied by a change in line profile; when the absorption becomes stronger, a P Cygni profile appears. We discuss SN 2011A in the context of interacting SNe IIn and SN impostors, which appears to confirm the uniqueness of this transient. While we favor an impostor origin for SN 2011A, we highlight the difficulty in differentiating between terminal and non-terminal interacting transients.
