Does Social Capital Affect Immigrant Political Participation? Lessons from a Small-N Study of Migrant Political Participation in Rome

Social capital captures the idea that relationships hold value. While this idea has intuitive appeal, there is significant debate regarding its utility to political science research. This article employs original data collected in Rome, Italy, to test a new model that recognizes the distinction between levels of social capital and introduces the idea of conflict between these levels into the field’s current theorizing on immigrant political participation. The findings presented here lend further support for the proposed relationship between migration-related factors, such as language proficiency and length of stay and participation. The article’s main finding is that the interactions between group-level and individual-level social capital plays an important role in shaping participation. Specifically, because it reinforces group-level social capital, bonding social capital favors participation in the formal, institutionally sanctioned activity of voting, while bridging social capital—which mitigates the effect of group-level social capital—favors participation in the informal political activity, protest.     

Attitudes Toward Affirmative Action: Correlations With Demographic Variables and With Beliefs About Targets,Actions, and Economic Effects1

Two studies assessed beliefs and attitudes toward affirmative action in the workplace. Opposition to affirmative action was most strongly associated with respondent race (White) and political conservatism, the belief that it involves strong actions (preferential hiring and setting aside jobs), and the expectation that it will hurt company performance. Attitudes were also positively associated with perceived frequency of employment discrimination experienced by the target group and negatively associated with their resulting employment opportunities. Regression results revealed that economic consequences for the company overwhelmed beliefs about target group employment opportunities in predicting affirmative action attitudes. Respondents associated aftirmative action most strongly with Black and Hispanic targets, and White respondents whose affirmative action schemas featured these 2 targets had the most negative attitudes.     

Use of a raster framebuffer in vision research

For the study of human and animal vision, the video framebuffer is the only technology that is capable of displaying two-dimensional images with precise control of contrast, luminance, and display timing. The video framebuffer also allows precise control of color. However, this device is not designed for precise psychophysical displays, and techniques must be developed to use them in this role. In this paper, we describe a number of basic methods used in our lab. In order to be concrete, we use an Adage RDS-3000 raster display system (Adage, 1982) as an example, since that is the device we have actually used. The Adage is hosted by a PDP-11/73 under the Venix operating system. The principles generalize to other machines. Where it clarifies the issues, we have shown the syntax of the software routines involved.     

Plain Semi-Post algebras as a poset-based generalization of post algebras and their representability

Semi-Post algebras of any type T being a poset have been introduced and investigated in [CR87a], [CR87b]. Plain Semi-Post algebras are in this paper singled out among semi-Post algebras because of their simplicity, greatest similarity with Post algebras as well as their importance in logics for approximation reasoning ([Ra87a], [Ra87b], [RaEp87]). They are pseudo-Boolean algebras generated in a sense by corresponding Boolean algebras and a poset T. Every element has a unique descending representation by means of elements in a corresponding Boolean algebra and primitive Post constants which form a poset T. An axiomatization and another characterization, subalgebras, homomorphisms, congruences determined by special filters and a representability theory of these algebras, connected with that for Boolean algebras, are the subject of this paper.To the memory of Jerzy SupeckiResearch reported here has been supported by Polish Government Grant CPBP 01.01     

α7 Nicotinic Receptor Subunits Are Not Necessary for Hippocampal-Dependent Learning or Sensorimotor Gating: A Behavioral Characterization of Acra7-Deficient Mice

The α7 nicotinic acetylcholine receptor (nAChR) subunit is abundantly expressed in the hippocampus and contributes to hippocampal cholinergic synaptic transmission suggesting that it may contribute to learning and memory. There is also evidence for an association between levels of α7 nAChR and in sensorimotor gating impairments. To examine the role of α7 nAChRs in learning and memory and sensorimotor gating, Acra7 homozygous mutant mice and their wild-type littermates were tested in a Pavlovian conditioned fear test, for spatial learning in the Morris water task, and in the prepulse inhibition paradigm. Exploratory activity, motor coordination, and startle habituation were also evaluated. Acra7 mutant mice displayed the same levels of contextual and auditory-cue condition fear as wild-type mice. Similarly, there were no differences in spatial learning performance between mutant and wild-type mice. Finally, Acra7 mutant and wild-type mice displayed similar levels of prepulse inhibition. Other behavioral responses in Acra7 mutant mice were also normal, except for an anxiety-related behavior in the open-field test. The results of this study show that the absence of α7 nAChRs has little impact on normal, base-line behavioral responses. Future studies will examine the contribution of α7 nAChR to the enhancement of learning and sensorimotor gating following nicotine treatments.     

An empirical investigation of regional differences in consumption behaviors in an emerging economy

Widely regarded as one of the most dynamic economies in Southeast Asia, Vietnam has increasingly attracted scholarly interest from diverse business disciplines. However, previous marketing research on Vietnam largely treats the country as a homogenous society. We draw on the literature in sociology, geography, history and predict that significant regional differences exist in consumers' consumption behaviors between the North and South of Vietnam, bearing important implications for international marketers. Using secondary survey data collected by an international market research firm, we show that consumers in Hanoi (HN) and Ho Chi Minh City (HCMC) differ greatly in how they perceive the impact of an economic crisis, how they change their consumption behaviors as a result, and whether they will cut back on spending on themselves, their families, and children. Our results also demonstrate that HN and HCMC consumers differ in their attitude toward luxury product consumption, attitude toward advertising, and marketing versus non-marketing controlled sources of information. Our research provides important implications for both managers and researchers interested in this fast-growing economy.     

Advancing a critical social psychological perspective on women's leadership: A case illustration from the Global South

When applied to the Global South, mainstream positivist approaches to work and organisational psychology impose alien theories of personality (the self) and leadership. In the case of women, they fail to capture the richness of their experiences of life and leadership, which are influenced by the nexus between history, power and marginalisation—for many, even oppression. The purpose of this article is to demonstrate the value of a critical social psychological approach, despite its grounding in the Global North discourse, to analyse women's leadership from a cross-cultural context. To illustrate, we provide an empirical example of a Vietnamese woman leader's life-story drawing on the theoretical resources from critical social psychology to interpret her experiences. When viewed from this perspective, women's leadership is understood within a dialogical space, which is prior to and more fundamental than any instrumental reason and technical rationality. It is argued that this approach resists essentialising assumptions about gender and cultural practices of leadership, providing a more liberating means to understand the life and leadership of Vietnamese women. In the final analysis, we argue that this study contributes to the nascent field of critical work and organisational psychology.     

Psychiatric Diagnoses and Clinical Characteristics of Asian American Youth in Children's Services

This study examined the psychiatric diagnoses and clinical characteristics of the 981 Asian American children enrolled in the first phase of the Comprehensive Community Mental Health Services for Children and Their Families Program. Asian Americans were less likely than non- Asian Americans to receive diagnoses of depression and ADHD and more likely to receive diagnoses of anxiety and adjustment disorder. As compared to non-Asians, Asian Americans were significantly more likely to be rated with severe functional impairment in community role performance, self-harmful behavior, and thinking. There was also a trend for fewer externalizing behavior problems. Implications for research and practice are discussed.     

Cultural Differences in the Reciprocal Relations between Emotion Suppression Coping,Depressive Symptoms and Interpersonal Functioning among Adolescents

The current study examined the prospective relations between emotion suppression and maladjustment (i.e., depressive symptoms, family stress events, peer stress events, and family and peer support) among Vietnamese American (n = 372) and European American adolescents (n = 304). We found that at baseline Vietnamese Americans adolescents reported greater use of emotion suppression coping than European American adolescents. Multi-group structural equation modeling indicated that for European American teens emotion suppression was significantly related to increased depression symptoms and decreased quality of peer relationships. In contrast, for the Vietnamese Americans teens emotion suppression relations to later maladjustment was either nonsignificant or attenuated relative to the European American. These findings suggest ethnic group differences in both the utilization, and consequences and function of emotion suppression among Vietnamese American and European American adolescents.     

Does Talker‐Specific Information Influence Lexical Competition? Evidence From Phonological Priming

In this study, we examined whether the lexical competition process embraced by most models of spoken word recognition is sensitive to talker‐specific information. We used a lexical decision task and a long lag priming experiment in which primes and targets sharing all phonemes except the last one (e.g., /bagaR/“fight” vs. /baga?/“luggage”) were presented in two separate blocks of stimuli. In Experiment 1, the competitor prime block was presented only once to listeners, and no modulation of the competitor priming effect as a function of a talker change between the primes and targets was observed. However, attenuation in the competitor priming effect in the case of a talker change between the primes and targets was observed in Experiment 2 in which the competitor prime block was presented five times to listeners. We discuss our findings in reference to hybrid models of spoken word recognition in which repetition of words with the same talker could be a key factor in the formation and access to talker‐dependent representations.
