A review of research on US Catholic education reveals that race is not treated as an important area of analysis like class
and gender. Black Catholics are rarely studied in education let alone mainstream writings. This article examines the social
and educational history of blacks in the US Catholic Church and the dual reality of inclusion and exclusion within a Church
and its schools. This paper focuses on the intersection of the Church and Black Catholic schools as enduring institutions
of opportunity for Black families and their communities. This paper unearths the shared values, assumptions and beliefs about
African American Catholics quest for literacy. The article uses Black Theology as a frame to explain how the intersections
of culture, history and religion influence meaning and educational decision-making. African Americans pursued Catholic education
for two reasons. First, they sought to be educated which both advanced their individual freedom but vastly improved their
community’s economic, social, and political standing. Second, they inserted their own unique cultural and social experiences
into Catholic schools which espoused service and academic excellence. Black Catholic schools well-defined values and academic
excellence is still viewed by African Americans as places of hope and opportunity for students of color. 相似文献

School psychologists and administrators are often asked to respond to student violence and disorder based on incomplete or inaccurate information about the nature and scope of these problems in their schools. Records of disciplinary actions and incidents may reflect only the tip of the proverbial iceberg. In national surveys, school administrators report rates of violence and disorder that are only a small fraction of the rates reported by students in national self‐report surveys. Student self‐report surveys on school violence and disorder may offer school officials a means of more accurately appraising the prevention needs of their students. This article compares the methods and findings of three national surveys of students in an effort to understand what methodological characteristics have the most salient impact on their findings. The article examines measures of school‐related weapon carrying and fear from all three national surveys contrasting their modes of administration and question phrasing. Estimates from even the most expertly designed and administered survey will include some error. However, the stability and comparability of the national surveys across time and across surveys suggest that student self‐report surveys are valuable tools for school‐level needs assessment. © 2001 John Wiley & Sons, Inc. 相似文献

The article employs deep log analysis (DLA) techniques, a more sophisticated form of transaction log analysis, to demonstrate what usage data can disclose about information seeking behaviour of virtual scholars – academics, and researchers. DLA works with the raw server log data, not the processed, pre-defined and selective data provided by journal publishers. It can generate types of analysis that are not generally available via proprietary web logging software because the software filters out relevant data and makes unhelpful assumptions about the meaning of the data. DLA also enables usage data to be associated with search/navigational and/or user demographic data, hence the name ‘deep’. In this connection the usage of two digital journal libraries, those of EmeraldInsight, and Blackwell Synergy are investigated. The information seeking behaviour of nearly three million users is analyzed in respect to the extent to which they penetrate the site, the number of visits made, as well as the type of items and content they view. The users are broken down by occupation, place of work, type of subscriber (“Big Deal”, non-subscriber, etc.), geographical location, type of university (old and new), referrer link used, and number of items viewed in a session. 相似文献

Ovarian cancer is the leading cause of death from gynecological malignancies in women. The primary challenge is the detection of the cancer at an early stage, since this drastically increases the survival rate. In this study we investigated the dielectrophoretic responses of progressive stages of mouse ovarian surface epithelial (MOSE) cells, as well as mouse fibroblast and macrophage cell lines, utilizing contactless dielectrophoresis (cDEP). cDEP is a relatively new cell manipulation technique that has addressed some of the challenges of conventional dielectrophoretic methods. To evaluate our microfluidic device performance, we computationally studied the effects of altering various geometrical parameters, such as the size and arrangement of insulating structures, on dielectrophoretic and drag forces. We found that the trapping voltage of MOSE cells increases as the cells progress from a non-tumorigenic, benign cell to a tumorigenic, malignant phenotype. Additionally, all MOSE cells display unique behavior compared to fibroblasts and macrophages, representing normal and inflammatory cells found in the peritoneal fluid. Based on these findings, we predict that cDEP can be utilized for isolation of ovarian cancer cells from peritoneal fluid as an early cancer detection tool. 相似文献

Scientific racism was widely used as a justification to oppose race-mixing in the United States. Historians have justly criticized this abuse of science, but have overlooked some of the important ways in which science was used in the 1930s and 1940s to overturn scientific racism and opposition to race-mixing. Of particular importance was the cultural anthropology of Franz Boas and the evolutionary biology of Theodosius Dobzhansky, which supplied arguments against racism and fundamentally altered the scientific understanding of race. 相似文献

This study examines the role of regional government quality in health-related participation in sport and physical activity among adults (18–64 years) in 28 European countries. The importance of the analysis rests in the relative autonomy that regional and local governments have over policy decisions connected with sport and physical activity. While existing studies have focussed on economic and infrastructural investment and expenditure, this research investigates the quality of regional governments across 208 regions within 28 European countries. The individual-level data stem from the 2013 Eurobarometer 80.2 (n?=?18,675) and were combined with regional-level data from Eurostat. An individual's level of participation in sport and physical activity was measured by three variables reflecting whether an individual's activity level is below, meets, or exceeds the recommendations of the World Health Organization. The results of multi-level analyses reveal that regional government quality has a significant and positive association with individual participation in sport and physical activity at a level meeting or exceeding the guidelines. The impact is much larger than that of regional gross domestic product per capita, indicating that regional disadvantage in terms of political quality is more relevant than being disadvantaged in terms of economic wealth. 相似文献

We identified the perceptual–cognitive skills and player history variables that differentiate players selected or not selected into an elite youth football (i.e. soccer) programme in Australia. A sample of elite youth male football players (n?=?127) completed an adapted participation history questionnaire and video-based assessments of perceptual–cognitive skills. Following data collection, 22 of these players were offered a full-time scholarship for enrolment at an elite player residential programme. Participants selected for the scholarship programme recorded superior performance on the combined perceptual–cognitive skills tests compared to the non-selected group. There were no significant between group differences on the player history variables. Stepwise discriminant function analysis identified four predictor variables that resulted in the best categorization of selected and non-selected players (i.e. recent match-play performance, region, number of other sports participated, combined perceptual–cognitive performance). The effectiveness of the discriminant function is reflected by 93.7% of players being correctly classified, with the four variables accounting for 57.6% of the variance. Our discriminating model for selection may provide a greater understanding of the factors that influence elite youth talent selection and identification. 相似文献

The logs of four universities using the OhioLINK journal system were evaluated for a period of fifteen months using deep log analysis methods in order to compare and contrast the information seeking behaviour of their users. Large differences were found, especially between the research and teaching universities. Methodological problems associated with making the comparisons are discussed in some detail especially in terms of defining online sessions. 相似文献
