Teachers often respond to the perils of teaching about religion by simply avoiding the subject. An investigation of secondary lesson plans on three prominent Martin Luther King, Jr. websites reveals little attention to the ideology of the civil rights movement, especially those touching on religious ideas. Ignoring King's religious views risks fundamentally misrepresenting his identity, his ideology, and his motivation for nonviolence. Stride Toward Freedom: The Montgomery Story, King's 1958 account of the Montgomery Bus Boycott articulates three key features of the theological framework that inspired his activism: the spiritual motivation for his leadership, the ethical basis for his strategy of nonviolent direct action, and the theological understanding of human nature that undergirded his leadership and strategy. These points provide a useful model for introducing King's ideas in the classroom. The effort to intentionally and thoughtfully teach religion could contribute one step toward inculcating genuine tolerance among students. Civil discourse is not fostered simply by identifying core principles everyone shares but also through thoughtful, critical engagement with disparate ideas, including what are, for many people, the most heavily freighted ideas.  相似文献

What is the emigration rate of a country, and how reliable is that figure? Answering these questions is not at all straightforward. Most data on international migration are census data on foreign-born population. These migrant stock data describe the immigrant population in destination countries but offer limited information on the rate at which people leave their country of origin. The emigration rate depends on the number leaving in a given period and the population at risk of leaving, weighted by the duration at risk. Emigration surveys provide a useful data source for estimating emigration rates, provided that the estimation method accounts for sample design. In this study, emigration rates and confidence intervals are estimated from a sample survey of households in the Dakar region in Senegal, which was part of the Migration between Africa and Europe survey. The sample was a stratified two-stage sample with oversampling of households with members abroad or return migrants. A combination of methods of survival analysis (time-to-event data) and replication variance estimation (bootstrapping) yields emigration rates and design-consistent confidence intervals that are representative for the study population.  相似文献

This paper calls for a paradigm shift in the production control literature away from assuming due date setting and order release are two independent decision levels. When order release is controlled, jobs do not enter the shop floor directly but are retained in a pre-shop pool and released to meet certain performance targets. This makes the setting of accurate planned release dates – the point at which jobs transition from the pool to the shop floor – a key consideration when setting due dates. We develop a new approach to estimating planned release dates to be embedded in the Workload Control (WLC) concept. Our approach is unique as it anticipates the release decision as part of the due date setting procedure. This makes a second independent release decision superfluous and avoids a major cause of tardiness – deviations between (i) the planned release date used when calculating the delivery time allowance and (ii) the actual, realised release date. Simulation is used to compare the performance of WLC using two decision levels with the new single-level approach where the release decision is anticipated when setting the due date. Performance improvements are shown to be robust to uncertainty in processing time estimates.  相似文献

Bottleneck shiftiness is an important managerial problem that negatively affects shop floor manageability. It has therefore received much research attention. Yet research has focused on how protective capacity can be used to influence bottleneck shiftiness rather than on assessing its operational impact. The latter is complex to evaluate since changing the degree of bottleneck shiftiness influences utilization, which makes the results of different experimental settings non-comparable. To overcome this problem, we take a different approach. Bottleneck shiftiness is decomposed by investigating its underlying phenomenon: the impact of the bottleneck position. Using simulation, we demonstrate that tighter control can be exercised, and better performance achieved, the further upstream the bottleneck is positioned. It is consequently important to be aware of the direction of the bottleneck shift. If the bottleneck shifts upstream, performance is likely to improve rather than deteriorate as is implicitly assumed in the literature.  相似文献

Money-back guarantees have become an increasingly popular tool for marketing managers??mainly because they are regarded as an effective means to signal product quality. However, from an academic perspective there is sparse empirical evidence on whether such a signaling effect really exists and, most importantly, whether it influences consumer decision making. Hence, the objective of the paper is to empirically analyze the consequences of money-back guarantees on consumer buying behavior in a holistic theoretical framework accounting for both cognitive and affective consumer responses. Our results reveal that the existence of the rather cognitively driven signaling effect of a money-back guarantee is contingent on several factors: Besides the type of the product (search versus experience good), it particularly depends on consumer knowledge as well as on whether a money-back guarantee is offered for a strong or for a rather weak brand. In addition, we show that a money-back guarantee also induces affective consumer responses which additionally contribute to consumer buying behavior. These responses are mainly due to the guarantee??s insurance function reducing consumer uncertainty about product features.  相似文献

Drawing upon insights from family research, this article argues that in modern Western societies the reflection of individual notions of family as well as the development of concepts of a fulfilling everyday family life has turned into a recurrent challenge throughout the life course, a challenge particularly relevant during family transitions. Professionals in the field of social work with families are increasingly faced with the task of supporting such processes of reflection and development. At the same time, there is little knowledge about how these processes look like. Building upon results of a pilot study and merging recent theoretical developments in family research with the (German) tradition of social pedagogy, a conceptual framework to study family concepts theoretically and empirically is developed. The potential as well as the limitations of this research approach are discussed drawing upon a case example taken from an ongoing longitudinal study. This study aims at revealing family concept-related processes of informal learning and thus provides an understanding of family development from a social pedagogic point of view. Finally, an outline will be given of how this research could contribute to develop an intervention method standing in the tradition of social pedagogy.  相似文献

We investigate whether journal articles winning a prestigious award of the Thyssen foundation have a higher impact in the scientific literature than a control group of non-awarded articles. In average, awarded articles harvest significantly more citations than articles in the control group. Most remarkably, the average citation rank exactly matches the rank order of awards. The top award earns most citations while the second award, the third award and the non-awarded articles exhibit citation counts in declining order. The correlation of award rank and impact does not vanish if we restrict citation counts to the year of publication and the year thereafter. In this time span the distinction of excellence is very unlikely having a genuine effect on the impact measure. Thus, we do not find support for the social constructivist hypothesis that the correlation of the jury decision and the article impact is explainable by a label of distinctiveness. On the contrary, the empirical data confirm that the jury is successful in the selection of articles which in average have a larger impact in the scientific community than non-awarded publications.  相似文献

I analyze differences in debt perception of households confronted with an objective debt burden. Using data from the German Socio-Economic Panel, my econometric analysis shows that a subjective debt burden is not only influenced by the current constellation of income, debt service and, possibly, the potential subsistence level. Expectations of the personal economic situation and several non-financial factors affect debt perception as well. Women report significantly higher subjective debt burdens. Unemployment is also associated with drastically higher self-assessed debt burdens even when controlling for the current financial situation and for expectations. Some differences in the subjective perception of objective debt burdens can be attributed to personality traits (such as locus of control) and life satisfaction. I draw the following conclusions: First, self-assessed debt burdens contain information beyond the current economic situation, e.g., expectations of future incomes. Second, relying on subjective debt statements can lead to biased results for policy analysis if the researcher does not account for non-financial factors.  相似文献
