Long-term exposure to organophosphate pesticides (OPs) without acute poisoning can lead to various OPs. Environmental exposure to organophosphate pesticides may be associated with depression and suicide attempts in a population living in a rural agricultural area. Patients (n = 149) suffering from major depressive disorder (with and without attempted suicide) and a control group of healthy individuals (n = 64) who had been living in the same rural district for at least 1 year were selected. Red blood cell acetylcholine esterase (RBC-AChE) activity was examined as the basis of evaluating the degree of chronic environmental exposure to OPs residues. There were negative association between RBC-AChE activity levels and suicide attempts, the number of past suicide attempts and hopelessness levels in the depressive patients. The results of the study may support the idea that environmental exposure to OPs may be associated with mental health in individuals living in agricultural districts who are not farmers or working in occupations with access to OPs.  相似文献

In Arabic, auxiliary verbs are necessary in the written language, but absent from the oral language. This is contrary to languages such as English and French in which auxiliary verbs are mandatory in both written and oral languages. This fact was exploited to examine if dissociation between written and oral forms affects reading measures like letter detection task and therefore to validate the phenomenon of the missing‐letter effect (MLE) and to replicate previous studies. In addition, the study examined whether auxiliary verbs in Arabic are considered as functional elements that constitute part of the structural frame. Sixty native Arabic speakers read a passage while looking for a target letter that was embedded in a preposition, an auxiliary verb or a content word. Results showed the typical MLE with more omissions for the preposition than for the content words. However, the results with the auxiliary verb are less clear. The functional and the syntactic roles of auxiliary verbs in Arabic are discussed.  相似文献

Inquiry engagement is a newly defined construct that represents the participation in carrying out practices of science and engineering to achieve learning outcomes and is influenced by learners’ personalities and teachers’ roles. Expectancy value theory posits that attainment values are important components of task values that, in turn, directly influence students’ achievement-related choices and performance. The current paper developed and validated the McGill Attainment Value for Inquiry Engagement Survey (MAVIES) with undergraduate students in STEM disciplines. The MAVIES is a 67-item, learner-focused survey that addresses four components that are theoretically important for engaging in scientific inquiry: (a) teachers’ roles, (b) students’ personalities, (c) inquiry learning outcomes, and (d) practices of science and engineering. Evidence for internal consistency and construct, content, and criterion validity was obtained from 85 undergraduates who had experience with scientific inquiry in diverse STEM fields. Confirmatory factor analyses confirmed factors that were consistent with role theory, Big Five personality traits, revised Bloom’s learning outcomes, and the Next Generation Science Standards. The MAVIES instrument is a reliable and valid instrument for measuring undergraduate students’ attainment values for scientific inquiry engagement in STEM disciplines.  相似文献

In most medical schools, summative practical examination in Anatomy usually takes the format of a “steeplechase” (“spotters” or “bell ringers”) conducted in the gross anatomy laboratory using cadaveric material and prosected specimens. Recently, we have started to administer similar examinations online using the quiz facility in WebCT? and Moodle?. This article chronicles how we conceived and developed this method within the peculiar nature of our medical school setting. Over a five year period, practical summative examinations were organized as “steeplechase” online. The online examinations were administered using WebCT? and later Moodle? learning management software. Assessment “objects” were created from the materials available for anatomy teaching. These were digital images of cadaveric materials, radiological, and prosected specimens. In addition, short video clips of 30 seconds duration demonstrating muscle action were produced. These objects were optimized for online viewing and then uploaded onto the learning management software. A bank of questions (multiple choice or short answer type) was then created and linked to the assessment objects. These were used in place of the steeplechase in the computer laboratory. This method serves a crucial purpose in places like ours where continuous availability of human cadavers is impossible. Although time consuming initially, once questions are setup online, future retrieval, and administration becomes convenient especially where there are large batches of students. In addition, the online environment offers distinct advantages with regards to image quality, psychometric analysis of the examination and reduction of staff preparation time compared to traditional “steeplechase.” Anat Sci Educ 4: 115–118, 2011. © 2010 American Association of Anatomists.  相似文献

柯坪土语是现代维吾尔语中的特殊土语或方言岛。通过分析最近获取的语料可知,由于音系处理方式上的差异和其他一些原因,柯坪土语在动词的无人称形式和体、态、人称、时、式等形态特征上,表现出与标准语和其他方言土语(包括和田方言)不同的很多特征。  相似文献

The article provides an understanding of unique characteristics of Japanese nationals in the United States of America (USA), their possible acculturation and assimilation levels, Japanese world view (assumptions, values and beliefs), and Japanese developmental psychological functions (Amae, On, Giri, Ninjo, and Ajase Complex). All these factors affect the determination of culturally sensitive techniques and approaches that would be best suited for each Japanese client. Information about assessment tools, and counselling and therapeutic strategies and techniques that may be effective is presented.  相似文献
