In the summer of 2004, it was revealed that the U.S. Census Bureau had provided tabulations in 2002 and 2003 on Arab Americans to the Department of Homeland Security that included detailed information on the number of people of Arab backgrounds living in selected ZIP codes. Although not a violation of law, the Census Bureau realized that this perceived breach of confidentiality would have a negative impact on public trust, and within a few months following the news of the Arab American tabulations it announced that it would no longer assist law enforcement and intelligence agencies with tabulations on ethnic groups and other sensitive populations. In spite of this damage control, we believe that the Bureau's tabulation of Arab Americans provides momentum to a process that adversely affects data quality by increasing both non-response and the cost of obtaining survey and census data. We argue that there are no “methodological fixes” that can repair the damage, and further that public relations campaigns and internal administrative changes are not optimal solutions because of the governing structure within which the Bureau currently operates. Ultimately, the best way to limit the damage already done is to effect a political solution. Toward this end we describe short- and long-term actions. In the long run, we recommend removing the Census Bureau from the Executive branch of government and re-structuring it under a permanent and non-political oversight panel similar to either the Federal Reserve Board or the Congressional Budget Office. Such a move would make a strong statement that the Bureau is non-partisan federal statistical agency. 相似文献

This article considers research from a preliminary study of Libyan children's accounts of their experience learning English as an additional language (EAL) within mainstream schools in the LJK. The analysis of interviews and classroom observations suggests that for equal opportunity to take place, local education authorities need to place greater emphasis on language and educational provision for newcomers to UK primary schools. In addition, there is still a communication barrier as well as a language barrier between home and school which needs to be addressed in order for children to adjust to and meet school requirements. In a similar way, parents of newly arrived children need to have clear expectations. The implications of this piece of research are extremely relevant for additional language acquisition in British schools and, in particular, for the education of newcomers whose circumstances are similar to those of the children in this study. This research also enables the voice of Arab children, as learners of the English language, to reach educators and policy makers, and empower them further in the research processes which inform British education policy. 相似文献

Conceptions are analyzed as being the emergences from interactions between three poles： scientific knowledge （K）, values （V） and social practices （P）. The teachers＇ beliefs and values have a direct influence on the way of understanding and teaching a topic. These beliefs must be taken into account in the content and strategies of the teacher＇s formation. In this paper, the authors discuss the importance of studying and analyzing these conceptions and present the results of the research on teachers＇ and future teachers＇ conceptions about sexual health education. In this topic, the conceptions could be deeply rooted not only in scientific knowledge but also in value systems and social practices, because teachers often refuse to teach the ethical, psychological, economic and social issues not strictly reducible to biology, such as sexuality health. The authors used a questionnaire prepared jointly within the European project Biohead-Citizen. 相似文献

The goal of this study was to determine the stability of Total Prostrate Specific antigen (PSA-T) and Free Prostrate Specific
Antigen (PSA-F) in archival serum stored at 4°C and −20°C and subjected to temperature shift due to interruption in power
supply. Our study showed that PSA-T was stable up to 285 days and PSA-F was stable for 158 days under these conditions. Since
power supply interruption is an unavoidable problem in developing nations, our study has implication on the validity of measurement
of PSA-T and PSA-F in serum that was not properly stored due to emergency situations and for certain types of retrospective
studies. 相似文献

In this paper we discuss the interaction between science policies (and particularly in the area of scientific research) and
higher education policies in Gulf and Mediterranean Arab countries. Our analysis reveals a discrepancy between the two sub-regions
with respect to integration in the global market, cooperation in scientific research and international mobility of students.
The paper discusses the implications of the analysis of reform policies and higher education restructuring. 相似文献

The level of seven acute phase proteins was estimated together with copper and zinc in two groups of 15 children each suffering
from hepatitis A (HAV) or Hepatitis B (HBV). The mean concentration of α-1 antitrypsin, α-2 macroglobulin, ceruloplasmin,
C3 and copper was increased uniformly in both the types of viral hepatitis. α-1 acid glycoprotein, haptoglobin and zinc levels
were decreased in both the infections. A significant decrease in albumin level was observed in HAV while the decrease was
not significant in HBV. All the paramenters were repeated after one month on the day of discharge following the disappearance
of clinical signs and symptoms wherein the haptoglobin level returned to normal in HAV. No change was observed in the level
of other acute phase proteins. The level of the trace elements returned to normal. The observed increase in the levels of
acute phase proteins at the onset does not seem to have any significant relation to the subsequent course of the disease.
However, the level of acute phase proteins and other biochemical parameters may indicate a delayed biochemical recovery phase
in conjunction with the underlying hepatic pathological changes in the course of viral hepatitis in spite of clinical recovery. 相似文献

In this study, the author investigated how four science teachers employed model-based teaching (MBT) over a 1-year period. The purpose of the research was to develop a baseline of the fundamental and specific dimensions of MBT that are present and absent in science teaching. Teacher interviews, classroom observations, and pre and post-student assessments were gathered. Using a Generate-Evaluate-Modify framework as a theoretical guide, the author identified three fundamental aspects of MBT that were not apparent in an analysis of the teaching methods. Drawing on these findings, the author hypothesizes the consequent impact of the absence of these aspects on MBT on students?? experiences and performance in science. Implications for core science teacher professional development activities on MBT are discussed. 相似文献

OBJECTIVE: The effects of both childhood and teenage experiences of domestic violence on adolescent-parent attachments were examined. METHOD: Israeli adolescents (M = 15.9 years) who were either victims of physical abuse, witnesses of physical spouse abuse, victims and witnesses of abuse, or neither victims nor witnesses of abuse were questioned about attachments to their parents using the Inventory of Parent and Peer Attachment [IPPA; Armsden, G. C., & Greenberg, M. T. (1987). The inventory of parent and peer attachment: Individual differences and their relationship to psychological well-being in adolescence. Journal of Youth and Adolescence, 16, 427-454]. FINDINGS: Abuse status 5 years earlier was unrelated to the adolescents' current perceptions of their attachments whereas current abuse status predicted the adolescents' perceptions of attachment to their mothers. Adolescents who were victims of physical abuse reported weaker attachments to their parents than adolescents who were not abused or who had solely witnessed interparental physical abuse. Attachments to mothers were weaker whether or not mothers were the perpetrators of abuse. CONCLUSIONS: These findings suggest that victimization adversely affects children's perceptions of relationships with their parents, but that changes in the exposure to family violence are associated with changes in relationships with parents. These findings suggest that intervention can have positive effects on parent-child relationships despite violent histories. 相似文献

The Seventh School Curriculum Reform in Korea was introduced in 2000 to prepare school‐aged Koreans for an information and knowledge‐based society. The reform effort emphasises information and communication technology (ICT) in the K–12 curriculum and a learner‐centred pedagogy. This study examines the contributions of ICT, specifically, computer‐assisted instruction (CAI), in Korean science classrooms. A sample of 234 Korean middle school students was categorised into five achievement groups. Data were collected from pre‐ and post‐achievement test scores and pre‐ and post‐questionnaires for attitudes toward science, future courses, and career aspirations in science. Findings include: (1) the lowest achievement group showed the most significant improvement after CAI (p=.000); (2) an improvement in student achievement in science significantly influenced students’ attitudes toward science (p=.019), future course selections, and career aspirations related to science (p=.000); and (3) boys tended to perform better with CAI than girls. This research provides evidence that CAI has the potential to help lower achieving students in Korean science classes and may encourage enrolment in science. 相似文献
