Thomas M. Philip Danny C. Martinez Eduardo Lopez Antero Garcia 《Race Ethnicity and Education》2016,19(1):182-199
Based on a two-year self-study by a group of early-career scholars of color, we explore and purposefully name our role, within the contemporary context of neoliberal reform, as educational researchers of color who are former K-12 teachers. We capture the insights that emerged from our self-study through a close reading of dominant neoliberal educational reform discourses, particularly through an examination of the writings of Michelle Rhee and Wendy Kopp. Along three dimensions of: (1) experience as teachers; (2) solidarity with teachers; and (3) analyses of racism in schooling, we characterize prominent discourses through which educators, researchers, and the public describe teachers and teaching. We name these discursive frames to make explicit the assumptions that are embedded in each and the intentional or inadvertent consequences of each. Finally, we propose a teacher solidarity lens through which we strive to approach our research and work with teachers. 相似文献

This article critically analyzes the origins and nature of American nationalism. The first part examines the historiographical debate on the question in what period the formation of an American national identity occurred, i.e. before or after the American Revolution. The second part is concerned with the nature of American nationalism, casting doubt on the claim that American nationalism is exceptional, i.e. inherently different and morally superior to other nationalisms. It refutes the exceptionalist claim by applying recent findings in European nationalism research to the American case and by reinterpreting American nationalism not as an introspective phenomenon but as a demarcation process. 相似文献

Is the Study of Happiness a Worthy Scientific Pursuit? 总被引:1,自引:1,他引:0
This paper critiques the view that the study of happiness is not a worthy scientific pursuit. The happiness set point and
hedonic treadmill theories denote the complexity of increasing happiness levels due to genetic limitations and adaptation,
however, there is mounting evidence to suggest that with the use of appropriate measures and specific interventions aimed
at fostering strengths and virtues, happiness can be increased. Furthermore, the benefits of investigating methods for increasing
happiness include improvements in physical, psychological and social health and well-being. It is concluded that approaching
human needs from a top down or holistic standpoint where individuals can use their strengths to overcome life’s challenges,
is beneficial to health and well-being. Hence, the study of happiness is a worthy scientific pursuit. 相似文献

The Anamnestic Comparative Self Assessment (ACSA) measure of subjective well-being (SWB) aims to reduce the problems of cultural
bias and relativity to external standards by allowing people to define the endpoints or ‘anchors’ of the measurement scale.
In medical terminology anamnestic denotes ‘based on memory’. The ACSA uses subjects’ memories of the best and worst periods
in their lives to define the anchors of the scale. They then assess their current quality of life relative to these personal
anchors. The South African pilot study tested the match between self-assessment of SWB with ACSA and the conventional single-item
measures of life satisfaction and happiness used in the South African Quality of Life Trends Study and analysed the narratives
of the best and worst times of life. The quota sample of 46 consisted of 26 residents of Makana district in the Eastern Cape
Province, South Africa, and 20 patients undergoing treatment in the local TB hospital. Mean SWB ratings with all three measures
of life satisfaction, happiness and ACSA were between 5 and 6 on a 0–10-point scale. Ratings on all three scales were positively
correlated. However, on ACSA the TB patients rated their current SWB 1.84 points lower than the community respondents, suggesting
a greater sensitivity of this measure. It was observed that the starting points of the life stories produced by respondents
to define the anchor periods for ACSA were related to their current assessment of SWB. A typology was developed that combined
the starting point of the life stories with current SWB. The majority of community respondents matched the ‘Achiever’ type
who scored positively on ACSA (i.e., above the mid-point of the scale) and whose life stories started with the worst period
of their lives and proceeded to the best period. The TB patients were the only respondents to represent the ‘Survivor’ type
whose morale had recovered after misfortune in life. ‘Survivors’ started their narratives with the best period in their lives,
then moved to the worst (often health-related) one, and gave positive ACSA ratings. Based on the qualitative analysis of narratives,
it is concluded that ACSA is a sensitive measurement instrument and therefore particularly useful for monitoring the effects
of treatments and social interventions in longitudinal studies. However, further research is required to verify its cross-cultural
validity.

This article uses a demographic approach and data from the Health and Retirement Survey, a nationally representative sample of the U.S. population, to investigate sex differences in the length of life lived with heart disease and after a heart attack for persons in the United States age 50 and older. On average, women live longer than men with heart disease. At age 50 women can expect to live 7.9 years and men 6.7 years with heart disease. The average woman experiences heart disease onset three years older and heart attacks 4.4 years older than men. 相似文献

This paper examines the relationship between subjective well-being and domain satisfactions. In the past different models have been specified. The most commonly applied model is the bottom-up model in which domain satisfactions affect subjective well-being. The more recent top-down model suggests a reversed relationship. Finally there is the supposition that the correlations between these variables can be spurious due to the effect of personality characteristics. Empirical research has shown that different models are found for different domains and in different countries. Focussing on the effects of the domain satisfactions of finances, housing and social contacts it has been found that subjective well-being is mainly affected by satisfaction with social contacts in Western developed countries and by satisfaction with finances in East European countries. The question we should like to answer in this study is whether a similar pattern obtains for the factors which influence subjective well-being among the different race groups in South Africa. Interestingly, coloured people and Asians did indeed show the expected effects but the groups with the most extreme living conditions did not. Evaluation of life circumstances by black and white South Africans was determined by expectations for the future rather than by current living conditions. This surprising result is discussed in the light of the political situation in South Africa. 相似文献

Drawing on Delgado and Yosso’s counterstory, Yosso’s community cultural wealth, and Alsup’s borderland discourses, the authors, who are women of color academics, use narratives from their lives to discuss the ways in which they draw on resources in managing and reconfiguring their multiple identities within the academy. These include identities of scholars, mentors, teachers, community members, mothers, and partners. They suggest that rather than merely being socialized into cultural reproduction, as much of the literature oriented toward women of color advises them to do in order to become successful, they seek to actually engage in transforming their roles and that of the academy by consciously and repeatedly making present and visible facets of identity that have previously been more-or-less absent in higher education. By presenting these counter-narratives the authors attempt to engage with ways of self-positioning that are, especially for women of color in academia, not frequently discussed or presented. 相似文献

Two heuristics based on branch and bound (B&B) are developed to solve closed-loop material requirements planning (MRP) lot-sizing problems that have general product structures and variable costs. A “look ahead method'’(LAM) heuristic allows for variable production/purchasing costs and uses a single-level B&B procedure to rapidly improve lower bound values; thus, LAM efficiently uses computer-storage capacity and allows solution of larger problems. The “total average modification'’(TAM) heuristic uses B&B, applied level by level, and modified setup and carrying costs to solve the variable production/purchasing costs MRP lot-sizing problem. LAM and TAM are tested on problems and compared to heuristics in the literature. TAM may be used to solve large MRP lot-sizing problems encountered in practice. 相似文献

Scientific techniques for inventory management typically are applied to systems containing many items. Such techniques require an estimation of the demand variance (and mean) of each item from historical data. This research demonstrates a significant potential for improvement in system cost performance from using least-squares regression fits of a variance-to-mean functional relation instead of the standard statistical variance estimate. Even when there is a moderate degree of heterogeneity among items and when the form of the variance-to-mean relation is misspecified, substantial cost savings may be realized. The cost of statistical uncertainty may be reduced by half. The research also provides evidence that system cost is fairly insensitive to the number of items used to fit the regression. This paper provides the underlying reason why a regression-derived variance estimator yields lower cost: it is less variable than the usual individual item variance estimator. 相似文献
