Perceiving and Feeling Personal Discrimination: Motivation or Inhibition for Collective action?

Relative deprivation and group consciousness theories differ in their predictions of how personal discrimination and personal discontent will be related to taking collective action. According to relative deprivation theory, assessments of personal status should be unrelated to taking collective action. In contrast, group consciousness theories suggest that while perceiving personal discrimination is necessary for collective action to occur, feelings of personal discontent may inhibit it. Female students completed questionnaires assessing their perceptions of, and affective responses to personal discrimination, as well as their participation in collective actions. A hierarchical regression analysis found that personal discrimination and discontent interacted such that among women who perceived personal discrimination, women took the most collective actions when they did not feel personally discontent with their status. Implications for the relationship between negative emotions and intergroup behavior were discussed

Double Relative Deprivation: Combining the Personal and Political

Double relative deprivation, which has been virtually ignored in research on relative deprivation, was expected to predict women\u27s collective action over and above egoistic and collective deprivation. The role of socio-political resources in perceiving deprivation and participation in action was also investigated. Female students (N=164) completed a questionnaire designed to assess their perceptions of egoistic, collective, double relative deprivation (defined as the interaction between egoistic and collective deprivation), resource availability and participation in collective action. Hierarchical regression analyses indicated that double relative deprivation predicted collective action over and above egoistic and collective relative deprivation, and that resource availability also uniquely predicted action. Implications for expanding conceptual and operational definitions of these constructs are discussed

Perceiving and responding to the Personal/group discrimination discrepancy

To explain why minority group members recognize less personal than group discrimination, research has focused on cognitive processes. While within self-categorization theory it may be argued the discrepancy is a function of a salient social self that perceptually discounts the personal self, it can also be argued that depersonalization allows for the cognitive possibility of perceiving similar amounts of personal and group discrimination. The present study suggested that, consistent with group consciousness theories, the social self may serve to both discount as well as integrate the social self, depending on the way in which the social self is defined. Using structural equation modeling, the present study found that defining the social self along social experiences was associated with lower personal/group discrimination discrepancy scores which in turn were associated with greater participation in collective action. Implications for different definitions of the social self were discussed

Responding to Sexual Discrimination: The effects of societal versus self-blame

While self-blame has been considered to be a useful coping tool for victims, its benefits within the context of group discrimination are equivocal. The present research hypothesized that women encouraged to engage in self-blame for sex discrimination would be more likely to endorse accepting their situation or endorse the use of individual, normative actions. In contrast, women encouraged to engage in societal blame for sex discrimination would be more likely to participate in non-normative actions aimed at enhancing the status of the group as a whole. Female students in Canada were subjected to a situation of discrimination and were encouraged to blame either themselves or social discrimination. They were then given the opportunity to respond to the discrimination by endorsing various actions. A profile analysis of the endorsed actions indicated that women encouraged to blame themselves were most likely to endorse accepting their situation, while women encouraged to blame society endorsed non-normative individual confrontation

The Informal Housing Crisis in Cape Town and South Africa

This study concerns the housing conditions of Africans in urban South Africa. Informal housing, or shack dwelling, is common although there are variations across provinces. Shack dwellings are self-built, often out of discarded building materials and packing cases. They are not subject to building codes and generally lack basic services including electricity, sewerage and running water. To acquire these services residents often illegally and dangerously tap into municipal facilities. The proportion of urban Africans living in shacks is unusually high in the Western Cape province, including its largest city Cape Town. In the Western Cape in 1997 statistics show over half of all urban Africans lived in informal housing. This was a rate twice as high as for South Africa as a whole. Ten years later this disparity was reduced but the rate of shack dwelling in the Western Cape was still sixty percent higher than in the whole country. Since the fall of the apartheid regime, Cape Town has become an increasingly popular destination for Africans re-locating from the former homelands in the Eastern Cape. Statistics show that the high rate of shack dwelling has no relationship to the relative wealth of urban Africans between provinces, nor to the length of time a person has resided in a shack. The extremely high rates of urban growth in the Western Cape over the past twenty years would appear to be part of the explanation. There are still questions surrounding the formal housing supply in the Western Cape though, and why it has not responded to this urban growth. The study draws on survey materials compiled periodically by the national statistical organization, Statistics South Africa. These allow relative frequencies to be derived and incorporated into cross-tabulations. Simple effect statistics are used to evaluate the hypotheses advanced in the research.No embarg

CAF-1 p150 and Ki-67 Regulate Nuclear Structure Throughout the Human Cell Cycle

The three-dimensional organization of the human genome is non-random in interphase cells. Heterochromatin is highly clustered at the nuclear periphery, adjacent to nucleoli, and near centromeres. These localizations are reshuffled during mitosis when the chromosomes are condensed, nucleoli disassembled, and the nuclear envelope broken down. After cytokinesis, heterochromatin is re-localized to the domains described above. However, the mechanisms by which this localization is coordinated are not well understood. This dissertation will present evidence showing that both CAF-1 p150 and Ki-67 regulate nuclear structure throughout the human cell cycle. Chromatin Assembly Factor 1 (CAF-1) is a highly conserved three-subunit protein complex which deposits histones (H3/H4)2 heterotetramers onto replicating DNA during S-phase of the cell cycle. The N-terminal domain of the largest subunit of CAF-1 (p150N) is dispensable for histone deposition, and instead regulates the localization of specific loci (Nucleolar-Associated Domains, or “NADs”) and several proteins to the nucleolus during interphase. One of the proteins regulated by p150N is Ki-67, a protein widely used as a clinical marker of cellular proliferation. Depletion of Ki-67 decreases the association of NADs to the nucleolus in a manner similar to that of p150. Ki-67 is also a fundamental component of the perichromosomal layer (PCL), a sheath of proteins that surrounds all condensed chromosomes during mitosis. A subset of p150 localizes to the PCL during mitosis, and depletion of p150 disrupts Ki-67 localization to the PCL. This activity was mapped to the Sumoylation Interacting Motif (SIM) within p150N, which is also required for the localization of NADs and Ki-67 to the nucleolus during interphase. Together, these studies indicate that p150N coordinates the three-dimensional arrangement of both interphase and mitotic chromosomes via Ki-67

Factor Model Forecasts for New Zealand

This paper focuses on forecasting four key New Zealand macroeconomic variables using a dynamic factor model and a large number of predictors. We compare the (simulated) real-time forecasting performance of the factor model with a variety of other time-series models (including the Reserve Bank of New Zealand’s published forecasts), and we gauge the sensitivity of our results to alternative variable-selection algorithms. We find that the factor model performs particularly well at longer horizons.

The p150N domain of chromatin assembly factor-1 regulates Ki-67 accumulation on the mitotic perichromosomal layer

Chromatin assembly factor 1 (CAF-1) deposits histones during DNA synthesis. The p150 subunit of human CAF-1 contains an N-terminal domain (p150N) that is dispensable for histone deposition but promotes the localization of specific loci (nucleolar-associated domains [NADs]) and proteins to the nucleolus during interphase. One of the p150N-regulated proteins is proliferation antigen Ki-67, whose depletion also decreases the nucleolar association of NADs. Ki-67 is also a fundamental component of the perichromosomal layer (PCL), a sheath of proteins surrounding condensed chromosomes during mitosis. We show here that a subset of p150 localizes to the PCL during mitosis and that p150N is required for normal levels of Ki-67 accumulation on the PCL. This activity requires the sumoylation-interacting motif within p150N, which is also required for the nucleolar localization of NADs and Ki-67 during interphase. In this manner, p150N coordinates both interphase and mitotic nuclear structures via Ki67

CO and CI maps of the starburst galaxy M82

The first map of an external galaxy in the 3P₁ - 3P0 fine-structure line of atomic carbon (CI) is presented towards the nucleus of the starbuster M82, and compared with the distinction of the CO J = 4 - 3 molecular emission. The CI traces features that are seen in lower transition CO maps, and shows that CI and the CO are well mixed and have similar spatial distributions. There are small differences between the CO J = 4 - 3 line and lower transition CO data towards the NE part of the molecular ring, where the emission is less prominent. The abundance ratio [CI]/[CO] across M82 is very high, with an average value ~ 0.5 across most of the nucleus, a factor at least 5 times that which is typical of dense molecular cloud cores seen in our own Galaxy. This means that on average, CI is overabundant towards M82. This result can be explained using models which provide enhancements to the CI abundance above normal Interstellar Medium values, a result of a greater cosmic ray flux in M82, or where there is substantial mixing of the gas
