The federal definition of emotional disturbance (ED) has been heavily criticized as vaguely defined and poorly operationalized yet there has not been a formal analysis of the reliability of the ED criteria. This study examined the reliability of the federal criteria for a special education designation of ED. A total of 179 school psychologists reviewed a mock special education report, made an eligibility determination, and provided information about their eligibility decision. In all, 56 participants found the student met ED eligibility criteria using 16 different combinations of the five criteria. Krippendorff’s α, a statistic preferred for content analysis, was calculated as a measure of criterion reliability. Results indicated extremely poor reliability (α = 0.2011). These findings demonstrate the importance of redefining the existing criteria.  相似文献

With the growth of social media, document sentiment classification has become an active area of research in this decade. It can be viewed as a special case of topical classification applied only to subjective portions of a document (sources of sentiment). Hence, the key task in document sentiment classification is extracting subjectivity. Existing approaches to extract subjectivity rely heavily on linguistic resources such as sentiment lexicons and complex supervised patterns based on part-of-speech (POS) information. This makes the task of subjective feature extraction complex and resource dependent. In this work, we try to minimize the dependency on linguistic resources in sentiment classification. We propose a simple and statistical methodology called review summary (RSUMM) and use it in combination with well-known feature selection methods to extract subjectivity. Our experimental results on a movie review dataset prove the effectiveness of the proposed methodology.  相似文献

Afro-Caribbean immigrants have been an integral part of the history and shaping of the United States since the early 1900s. This current study explores the experiences of five Afro-Caribbean faculty members at traditionally White institutions of higher education. Despite the historical presence and influence of Afro-Caribbean communities and the efforts within education systems to address the needs of Afro-Caribbean constituents, Afro-Caribbean faculty members continue to be rendered indiscernible in higher education and to be frequently and erroneously perceived as African–Americans. The study examines the lived experiences of these individuals in the hegemonic White spaces they occupy at their institutions with both White and Black populations. Through their narratives, issues of stereotyping, microaggression, and isolation are addressed. The participants also offer solutions to address these issues by university administrators, department heads, faculty development professionals, diversity officers, policy makers, and other stakeholders. The voices in this study shed light on an overlooked, misunderstood, and under-researched population within our faculty ranks in the American Academy.  相似文献

This study was undertaken to evaluate the role of serum neuron specific enolase (NSE) in prediction of disability and neurological worsening in hypertensive ischemic cerebrovascular stroke. 80 hypertensive ischemic stroke patients diagnosed by a neurologist as per WHO definition along with radiological findings suggestive of cerebrovascular stroke and differentiating from hemorrhagic stroke and 60 controls having essential hypertension coming to hospital because of regular checkup or headache but with no neurological disease were included in the study. Neurological disability was assessed by NIHSS at the time of admission (within 72 h from the onset of stroke) and on 7th day after admission and cases were categorized into mild, moderate and severe disability. Venous blood samples were drawn within 72 h from the onset of symptoms. The samples were processed as per the laboratory protocol. The serum NSE samples were analyzed using an enzyme immunoassay based on the sandwich technique. We observed raised serum NSE in hypertensive ischemic stroke (17.4 ± 5.4 ng/ml) with significant association between different hypertensive groups than in hypertensive controls (9.1 ± 0.75 ng/ml). Greater degree of disability was observed in hypertensive stroke patients with raised serum NSE and hypertensive patients with mean serum NSE level of 22.9 ± 3.6 ng/ml and dyslipidemia had greater probability of neurological worsening as compared to those with mean serum NSE level of 12.7 ± 1.2 ng/ml. Serum NSE levels can serve as a peripheral indicator of neuronal damage and assist in the prediction of disability and clinical outcome in hypertensive cerebrovascular ischemic stroke patients.  相似文献

职业技术教育最早被看作是培养产业后备军的途径,后来被看作是提高人力资本构成、生产力和就业的手段,今天,人们又认识到它对人的充分发展具有重要作用。人的发展既是国家发展的手段又是国家发展的目的,发展中国家需要一支有熟练技能和适应性强的劳动大军才能抓住发展机会,然而,发展中国家与发达国家的差距还在继续扩大,部分原因是虽然发展中国家注意到了对人的投资,认识到了职业教育与培训的重要性,但发展速度还太慢。职业教育与培训对于降低失业至关重要,但其作用的充分发挥必须依赖于职业教育与培训自身的改善、政府行为的改善、经济形势的好转和妇女就业领域的扩大等前提条件。  相似文献

Targeted Support for Using Technology-Enhanced Science Inquiry Modules   总被引:1,自引:1,他引:0  
Designing effective professional development experiences for technology-enhanced inquiry instruction is the goal of the Technology Enhanced Learning in Science (TELS) NSF funded Center for Learning and Teaching. In order to provide this type of support to a large number of teachers, we devised a targeted professional development approach. Participating teachers implemented short inquiry modules that featured interactive scientific visualizations. We collaborated with 16 schools in eight districts and five states. This paper reports the design, implementation, and refinement of the targeted approach. Findings from interview data show that teachers faced challenges that are often associated with enacting technology innovations in K-12 classrooms. The targeted professional development approach addressed the challenges and allowed teachers to successfully implement the modules in their classrooms. The interview data clarify teachers’ perspectives on how using technology impacted their teaching practices and their ideas about student learning. This work contributes to a growing body of literature that identifies and addresses barriers to integrating technology into K-12 classrooms.  相似文献

The medical, agricultural and biotechnological importance of the primitive eukaryotic microorganisms, the Fungi was recognized way back in 1920. Among various groups of fungi, the Aspergillus species are studied in great detail using advances in genomics and proteomics to unravel biological and molecular mechanisms in these fungi. Aspergillus fumigatus, Aspergillus flavus, Aspergillus niger, Aspergillus parasiticus, Aspergillus nidulans and Aspergillus terreus are some of the important species relevant to human, agricultural and biotechnological applications. The potential of Aspergillus species to produce highly diversified complex biomolecules such as multifunctional proteins (allergens, antigens, enzymes) and polyketides is fascinating and demands greater insight into the understanding of these fungal species for application to human health. Recently a regulator gene for secondary metabolites, LaeA has been identified. Gene mining based on LaeA has facilitated new metabolites with antimicrobial activity such as emericellamides and antitumor activity such as terrequinone A from A. nidulans. Immunoproteomic approach was reported for identification of few novel allergens for A. fumigatus. In this context, the review is focused on recent developments in allergens, antigens, structural and functional diversity of the polyketide synthases that produce polyketides of pharmaceutical and biological importance. Possible antifungal drug targets for development of effective antifungal drugs and new strategies for development of molecular diagnostics are considered.  相似文献

Many higher education institutions use student evaluation systems as a way of highlighting course and lecturer strengths and areas for improvement. Globally, the student voice has been increasing in volume, and capitalising on student feedback has been proposed as a means to benefit teacher professional development. This paper examines the student evaluations at a university in Trinidad and Tobago in an effort to determine whether the student voice is being heard. The research focused on students’ responses to the question, ‘How do you think this course could be improved?’ Student evaluations were gathered from five purposefully selected courses taught at the university during 2011–2012 and then again one year later, in 2012–2013. This allowed for an analysis of the selected courses. Whilst the literature suggested that student evaluation systems are a valuable aid to lecturer improvement, this research found little evidence that these evaluations actually led to any real significant changes in lecturers’ practice.  相似文献

Nurses play a significant role in geriatric care. However, as the aging population and demand for geriatric nurses increase worldwide, shortages of nurses seem to arise. This creates the need to assess and address the motivation and attitudes of nurses toward geriatric care. The intent of this qualitative study is to surface the essence or the “lebenswelt” that describe the motivation and attitudes of a selected group of Filipino nurses toward geriatric care. A total of six registered nurses who had experienced taking care of elderly patients voluntarily participated as respondents of this study. A two-part instrument developed by the researchers was made to elicit necessary data and information. The first part comprised of the robotfoto intended to establish the baseline characteristics of nurses under study. The second part consisted of a semistructured individual in-depth interview using “aide memoire” to probe into the motivation and attitudes of the nurse respondents. Field texts were phenomenologically reduced via repertory grid. Two distinct and interesting themes, namely Geriatric Service Motivation Typology and the Yin-Yang of Geriatric Attitudes emerged. The first theme includes the Single Loop and Double Loop type of motivation The former involves a transactional and unidirectional process, while the latter constitutes a two-way relational and transformational process. The second theme consists of a harmonious combination of the two sides of the nurses' attitudes toward geriatric care. Through this study, the human side of nursing is seen and captured, thus increasing the awareness and knowledge of nurses, improving provision of optimum geriatric care, and inspiring nurses to pursue geriatric nursing with a yearning to serve the elderly with and from the heart.  相似文献
