The term technological gender gap refers to the idea that males and females have different technology-related attitudes, behaviors, and skills. This article reviews the mounting evidence documenting the existence of a gender gap, which, if ignored, could render large numbers of female students unprepared to meet the technological challenges of the future. Recommendations for ameliorating the technological gender gap are presented for educators and computer-based instruction (CBI) designers who are interested in providing equitable educational opportunities for male and female students. 相似文献

Current recommendations of the Adult Treatment Panel and Adolescents Treatment Panel of National Cholesterol Education Program
make the low-density lipoprotein cholesterol (LDL-C) levels in serum the basis of classification and management of hypercholesterolemia.
A number of direct homogenous assays based on surfactant/solubility principles have evolved in the recent past. This has made
LDL-C estimation less cumbersome than the earlier used methods. Here we compared one of the direct homogenous assays with
the widely used Friedewald’s method of estimation of LDL-C to see the differences and correlation. We used direct homogenous
assay kit to estimate serum LDL-C and high-density lipoprotein cholesterol (HDL-C). Serum Triglyceride (TG) and Total Cholesterol
(TC) was estimated and using Friedewald’s formula LDL-C was calculated. The LDL-C level obtained by both methods in 893 fasting
serum samples were compared. The statistical methods used were paired t-test and Pearson’s correlation.
There was significant difference in the mean LDL-C levels obtained by the two methods at the TG levels <200 mg/dl (p<0.02)
and TC levels >150 mg% (p<0.001). The correlation coefficient (r) between Friedewald’s and direct assay estimation was 0.88.
Friedewald’s method classified 23.5 % of patients as high cardiac risk whereas there were 17.58% by direct assay.
Both had good correlation even though the serum triglyceride and total cholesterol levels affect the difference in LDL-C estimated
by both methods. Taking into account the cost and performance, Friedewald’s method is as good or even better for classifying
and managing patients. 相似文献

Purpose: Globally, many extension professionals and policy-makers are advocating fee based services, in addressing the fund shortage and sustainable provision of agricultural advisory services. Hence, the article attempts to expose the farmers' willingness to pay (WTP) as agricultural extension in Bangladesh is experiencing chronic fund crisis.
Methodology: This study used contingent valuation method (CVM) for investigating farmers' WTP. Logit and Tobit model was employed to assess the determinants of WTP and amount willing to pay (AWTP) respectively. Besides, different qualitative methods were employed to have a deeper understanding of the research problems.
Findings: WTP was conditioned by providing quality extension services at farm and/or home of the farmers. The study also focused on farmers preferred mode of payment, criteria influencing payment decisions and the type of services for which they are willing to pay. Paid model can contribute to quality extension services, if started with a market oriented commodity based approach accompanied by adequate crop insurance support.
Practical implications: The study considered international experiences and national crisis in delivering extension services that provoke actions towards changing the extension policy of Bangladesh. The findings also prompt the factors that influence the paid extension service delivery for the crop farmers of Bangladesh.
Originality: Although, many studies have been conducted on privatisation of agricultural extension around the globe, we are not aware of any single study on crop farmers' willingness to pay for the extension services in Bangladesh. 相似文献

Almost all schemes that have been issued by scholars or researchers to present Maslow＇s hierarchy of basic needs include a pyramid （triangle） in which the physiological needs are in the base and the self-actualization needs are in the top of the triangle. Although this scheming is inspiring to some results, basic needs have more characteristics that are significant however, this scheming is not able to inspire. Based on elaborating Maslow＇s theory and research＇s findings, this study aims to disclose weaknesses and strengths of traditional scheme （triangle）, and develop two innovated schemes of basic needs, which are more close to Maslow＇s ideas and more inspiring to realize the actuality of this hierarchy. 相似文献

Background: Many medical schools require a student thesis before graduation. Publishing results in a peer‐reviewed journal could be an indicator of scientific value and acceptability by the scientific community. The publication pattern of theses published by medical students in Peru is unknown. The aim of this study was to assess the characteristics and publication pattern of theses in biomedical‐indexed journals conducted by medical students in a university with the highest research output in Peru. Methods: Data from registered theses between 2000 and 2003 were obtained from the university library. Publication of theses in biomedical journals was assessed in 2008 by a search strategy using PubMed, Google Scholar, LILACS, LIPECS and SciELO. Results: Four hundred and eighty‐two medical theses were registered between 2000 and 2003; 85 (17.6%) were published in biomedical‐indexed journals. Of the published theses, 28 (5.8%) were published in MEDLINE‐indexed journals, 55 (11.4%) in SciELO‐indexed journals, 61 (12.6%) in LILACS‐indexed journals and 68 (14.1%) in LIPECS‐indexed journals. Most of the published theses (80%) were in Spanish and published in Peruvian journals; and 17 theses (20%) were published in foreign journals (all of them indexed in MEDLINE). In addition, 37 (43.5%) belong primarily to internal medicine, and 24 (28.2%) belong primarily to infectious diseases. Medical students were first authors in 71 (83.5%) of the articles. Conclusion: In this study, most of the published theses were in Spanish, published in local journals and indexed in LIPECS. The percentage of published theses in biomedical journals at this university is comparable with others coming from developed countries. 相似文献

The study was aimed at presence of specific IgE antibody levelsinvitro to the identified antigen. Based on positive skin test with Gynandropsis gynandra and elevated levels of total IgE (>325
IU/ml) 104 patients were selected. Healthy, asymptomatic individuals (25) with low total IgE (<325 IU/ml) were included as
controls. The mean OD values by ELISA for specific IgE were 0.67±0.21, 0.57±0.18 and 0.56±0.18 with whole pollen antigen,
46-37 kD fraction and 36-32 kD fraction, respectively. The specificity and sensitivity between skin test positivity with whole
pollen antigen verses fraction with mol.wt 46-37 kD was 90% and 90% and for fraction with mol.wt 36-32 kD was found to be
81.1% and 89.4%. The clusters with molecular weights 46-37 kD and 36-32 kD may be useful inin vitro diagnostic test. Fractions within these clusters need to be identified for a higher specificity. 相似文献

Background
Degenerative cervical myelopathy (DCM) is a recently proposed umbrella term for symptomatic cervical spinal cord compression secondary to degeneration of the spine. Currently literature searching for DCM is challenged by the inconsistent uptake of the term ‘DCM’ with many overlapping keywords and numerous synonyms.Objectives
Here, we adapt our previous Ovid medline search filter for the Ovid embase database, to support comprehensive literature searching. Both embase and medline are recommended as a minimum for systematic reviews.Methods
References contained within embase identified in our prior study formed a ‘development gold standard’ reference database (N = 220). The search filter was adapted for embase and checked against the reference database. The filter was then validated against the ‘validation gold standard’.Results
A direct translation was not possible, as medline indexing for DCM and the keywords search field were not available in embase . We also used the ‘focus’ function to improve precision. The resulting search filter has 100% sensitivity in testing.Discussion and Conclusion
We have developed a validated search filter capable of retrieving DCM references in embase with high sensitivity. In the absence of consistent terminology and indexing, this will support more efficient and robust evidence synthesis in the field. 相似文献10.

Norman Geschwind had a profound effect on behavioral neurology, not only on the basis of his research and theories expressed
during his lifetime, but also through the impact that he had on colleagues privileged to train under him or have their work
personally influenced by him. My work falls into the latter category. Novel associations between brain function/structure
and behavior characterized his professional contributions, and offer a model for those who follow in his footsteps. He correctly
predicted that like aphasic disorders, developmental dyslexia might be associated with deficits in color naming expressed
currently as deficits in Rapid Automatized Naming. He stimulated anatomic research regarding patterns of asymmetry and microscopic
architecture leading to the establishment of the Orton Dyslexia Neuropathology Laboratory at Beth Israel Hospital, Boston.
He predicted an association between autoimmune disorders and reading disorders, an association that proved to be of genetic
origin. He further predicted that reading disorders, like language disorders, would be cross-cultural and, similarly, their
mechanism of production would be cross-cultural, although affected perhaps by the structure of the language to be learned.
His suspicion that the clinical impression of male gender preponderance in dyslexia was accurate and carried biologic significance
has recently been reconfirmed by colleagues at the Mayo Clinic in Rochester, Minnesota. Finally, with respect to dyslexia,
one should not be surprised that since affect is influenced by brain architecture, developmental disorders characterized by
altered brain architecture might be associated with affective or other psychiatric phenomena. My own work suggests that the
altered neuroanatomy in dyslexia may be accompanied by altered clinical neurophysiology, offering the possibility that in
some developmental disorders, behaviors, including academic aptitude and cognitive function, might benefit from medications
designed originally to lower the risk of clinical seizures. Perhaps Geschwind’s greatest lesson is to not assume that all
we have been taught as dogma is truth. Rather, we must have a willingness to make clear perceptions and draw conclusions that
come closer to the reality of the causal relationship between brain and behavior. 相似文献
