Experiencing Community through the Asian American Lens: A Qualitative Study of Photovoice Participants

The purpose of this study was to understand why there is such lack of citizen participation among Asian Americans, despite the exponential growth of Asian American population in the state. Based on the literature on sense of community, citizen participation, and psychological empowerment, it was speculated that how individuals experience community may influence their motivation to participate. With the goal to understand and document how Asian Americans define community and experience sense of community, a sample of Asian Americans were interviewed. These individuals were participants of the Photovoice project conducted by a local community-based organization. The second aim of the study was to explore if and how a project like Photovoice enhanced the sense of community among participants. The findings suggested that Asian Americans defined various types and multiple communities. Also, it was suggested that because Asian American community is an imposed community of people of diverse Asian background, Asian Americans may not necessarily define it as a community or experience sense of community within the community. Based on the experiences of the participants, Photovoice seem to have great potential in bringing such diverse group as Asian Americans together as a community. Limitations of the study and future directions are discussed

Asian American Perceived Racism: Acculturation, Racial Identity, Social Context, and Sociopolitical Awareness as Predictors of Asian American Perceived Racism

Asian Americans are believed to be immune to social barriers and challenges, because of their successes in the U.S. society. This belief, also known as the model minority myth, has caused Americans including Asian Americans themselves to believe that they are not faced with social challenges such as racism. The goal of this study was to examine the relationship among acculturation, racial identity, social context and sociopolitical awareness. Series of multiple regressions were conducted to examine the predictive model. The findings suggested three plausible models of perceived racism among Asian Americans. First two models suggested that racism should be distinguished from stereotypes. Third possible model suggested that racial identity and social context may mediate the relationship between assimilation and perceived racism. The study’s psychological and societal implications are discussed

Collective Josephson vortex dynamics in a finite number of intrinsic Josephson junctions

We report the experimental confirmation of the collective transverse plasma modes excited by the Josephson vortex lattice in stacks of intrinsic Josephson junctions in Bi$_{2}$Sr$_{2}$CaCu$_{2}$O$_{8+x}$ single crystals. The excitation was confirmed by analyzing the temperature ($T$) and magnetic field ($H$) dependencies of the multiple sub-branches in the Josephson-vortex-flow region of the current-voltage characteristics of the system. In the near-static Josephson vortex state for a low tunneling bias current, pronounced magnetoresistance oscillations were observed, which represented a triangular-lattice vortex configuration along the c axis. In the dynamic vortex state in a sufficiently high magnetic field and for a high bias current, splitting of a single Josephson vortex-flow branch into multiple sub-branches was observed. Detailed examination of the sub-branches for varying $H$ field reveals that sub-branches represent the different modes of the Josephson-vortex lattice along the c axis, with varied configuration from a triangular to a rectangular lattices. These multiple sub-branches merge to a single curve at a characteristic temperature, above which no dynamical structural transitions of the Josephson vortex lattice is expected

Heating-compensated constant-temperature tunneling measurements on stacks of Bi2_2Sr2_2CaCu2_2O8+x_{8+x} intrinsic junctions

In highly anisotropic layered cuprates such as Bi$_2$Sr$_2$CaCu$_2$O$_{8+x}$ tunneling measurements on a stack of intrinsic junctions in a high-bias range are often susceptible to self-heating. In this study we monitored the temperature variation of a stack ("sample stack") of intrinsic junctions by measuring the resistance change of a nearby stack ("thermometer stack") of intrinsic junctions, which was strongly thermal-coupled to the sample stack through a common Au electrode. We then adopted a proportional-integral-derivative scheme incorporated with a substrate-holder heater to compensate the temperature variation. This in-situ temperature monitoring and controlling technique allows one to get rid of spurious tunneling effects arising from the self-heating in a high bias range.Comment: 3 pages, 3 figure
