To determine the attitude of general practitioners towards continuing medical education (CME) and reasons motivating or hindering them from attending CME procedures, we conducted a cross-sectional survey from November 2013 to April 2014 in Karachi. Three hundred general practitioners who possessed a medical license for practice in Pakistan filled a pre-designed questionnaire consisting of questions pertaining to attitudes towards CME. Data was entered and analyzed using SPSS v16.0. 70.3% (n = 211) of the participants were males. Mean age was 47.75 ± 9.47 years. Only 67.33% knew about CME and only 52% had attended a CME session. Reasons for attending CME procedures reported were: need for updating knowledge, skills and competencies (67.30%), opportunity to meet colleagues (18.58%) and presenting scientific papers (8.97%). Mean Likert score was 1.67 (±0.667) for those who thought CME is worthwhile and 1.44 (±0.686) for those who consider their clinical duties as the major hurdle in attending CME procedures. Most common cause for not attending CME was lack of knowledge (32.66%) followed by time constraint (24%). Most physicians were not sufficiently informed about the potential benefits of CME and had never attended a CME session. Most common reason for attending CME procedures reported was need for updating knowledge, skills and competencies while reasons hindering physicians from attending CME were lack of knowledge and time constraint. 相似文献

Examining age differences in motor learning using real‐world tasks is often problematic due to task novelty and biomechanical confounds. Here, we investigated how children and adults acquire a novel motor skill in a virtual environment. Participants of three different age groups (9‐year‐olds, 12‐year‐olds, and adults) learned to use their upper body movements to control a cursor on a computer screen. Results showed that 9‐year‐old and 12‐year‐old children showed poorer ability to control the cursor at the end of practice. Critically, when we investigated the movement coordination, we found that the lower task performance of children was associated with limited exploration of their movement repertoire. These results reveal the critical role of motor exploration in understanding developmental differences in motor learning. 相似文献

Examining the role of two aspects of eWOM in online repurchase intention: An integrated trust–loyalty perspective 下载免费PDF全文
As electronic word‐of‐mouth (eWOM) has become an influential information resource for digital consumers who purchase products, understanding how the 2 ways of eWOM influence consumers' online repurchase intention (ORPI) becomes very pivotal. Despite its importance, there is no study in the literature that examined receiving and participating aspects of eWOM in an integrated perspective. The purpose of this study is to understand how 2 controversial eWOM aspects influence ORPI of consumers. Moreover, this study examines the mediating roles of e‐trust and e‐loyalty in the association between 2 sides of eWOM aspects and ORPI. The results indicated that 2 eWOM receiving factors, eWOM quality and eWOM quantity, have positive influences on e‐trust and ORPI. However, as an eWOM participating factor, the eWOM content has no significant influence on ORPI whereas another participating factor, the eWOM intensity, has the greatest impact on ORPI. Furthermore, the findings illustrate that e‐trust has a complementary mediation effect in the association between 2 receiving eWOM aspects and ORPI; likewise, e‐loyalty has a complementary mediation in the relationship between 2 participating eWOM aspects and ORPI. 相似文献

Pigeons responded in a perceptual categorization task with six different stimuli (shades of gray), three of which were to be classified as "light" or "dark", respectively. Reinforcement probability for correct responses was varied from 0.2 to 0.6 across blocks of sessions and was unequal for correct light and dark responses. Introduction of a new reinforcement contingency resulted in a biphasic process of adjustment: First, choices were strongly biased towards the favored alternative, which was followed by a shift of preference back towards unbiased choice allocation. The data are well described by a signal detection model in which adjustment to a change in reinforcement contingency is modeled as the change of a criterion along a decision axis with fixed stimulus distributions. Moreover, the model shows that pigeons, after an initial overadjustment, distribute their responses almost optimally, although the overall benefit from doing so is extremely small. The strong and swift effect of minute changes in overall reinforcement probability precludes a choice strategy directly maximizing expected value, contrary to the assumption of signal detection theory. Instead, the rapid adjustments observed can be explained by a model in which reinforcement probabilities for each action, contingent on perceived stimulus intensity, determine choice allocation. 相似文献

Identification of the second of two targets (T1, T2, inserted in a stream of distractors) is impaired when presented within 500 ms after the first (attentional blink, AB). Barring a T1-T2 task-switch, it is thought that T2 must be backward-masked to obtain an AB (Giesbrecht &; Di Lollo, Journal of Experimental Psychology: Human Perception and Performance, 24, 1454-1466, 1998). We tested the hypothesis that Giesbrecht &; Di Lollo's findings were vitiated by ceiling constraints arising from either response scale (experiment 1) or data limitations (experiment 2). In experiment 1, digit-distractors were replaced with pseudoletters to increase task difficulty, bringing performance below ceiling. An AB occurred without backward masking of T2. In experiment 2, a ceiling-free procedure estimated the number of noise dots needed for 80% T2 identification. An AB was revealed: fewer noise dots were required during the AB period than outside it. Both outcomes confirm that an AB can be obtained without either masking of T2 or task switching. 相似文献

Results from a screening program for sickle cell disease and β-thalassemia suggest about 90% of couples in Saudi Arabia at
risk of having affected children still decide to marry. This study determined the rate of at-risk marriages and identified
several factors that may prevent at risk couples from marrying. The marriage status of 934 at-risk couples was determined
from original screening program records in the Ministry of Health. Of 934 couples, 824 married (88.2%) and 110 (11.8%) did
not. A case–controlled study was conducted on 104 couples who did not marry (cases) and 478 couples who did marry (controls)
in order to assess relationships between various cultural and social factors and marriage decisions. In the case-controled
study, 28.8% of couples (30/104) who did not marry (cases) knew their disease or carrier status before screening compared
to 18% (86/478) of those who married (controls). Reasons couples gave for proceeding with marriage included: wedding plans
could not be canceled, and fear of social stigma. Couples who did not marry reported being influenced by prior knowledge of
their disease or carrier status and whether they or family members were affected. Approximately half of the cases and controls
(n = 270, 46.4%) thought it best to undergo screening before proceeding with the engagement and wedding plans. Most couples
received no advice to participate in genetic counseling services. Marriage decisions for the small number who received genetic
counseling (n = 168, 27.6%) did not differ significantly from those that received no counseling. Recommendations are made for improving
the effectiveness of this screening program. 相似文献

Campus open spaces play an important role in meeting socialization and personal development needs of youth. Various studies have shown that space use of youth is different from that of general society: particularly their psychosocial nature and the activities they carry out toward this nature differ from those of the children and adults. However, only a limited number of studies have produced findings on the needs of youth toward obtaining gains related to development of psychosocial nature required to carry out the activities aimed at meeting such needs. This study analyzed the use of campus open spaces by youth. The most preferred 3 places in study area have been chosen, and with behavioral observation, the activity types occurred in these places were identified. Which of these activities are for personal development and which of them are for social development were determined. 相似文献

This article presents how today's technology permeates the planning, organizing, staffing, leading, and controlling functions of human resources management. Certain industries or occupations are more reliant on technology and thus impose more physical and emotional stressors on employees. The effects of physical stressors and the physical manifestations of emotional stressors can expose employers to additional liability. The authors make 8 propositions in this study and provide supporting research with additional information. How employers can be proactive by encouraging task‐focused coping with stress is also discussed. 相似文献

Adults show a deficit in their ability to localize tactile stimuli to their hands when their arms are in the less familiar, crossed posture. It is thought that this ‘crossed‐hands deficit’ arises due to a conflict between the anatomical and external spatial frames of reference within which touches can be encoded. The ability to localize a single tactile stimulus applied to one of the two hands across uncrossed‐hands and crossed‐hands postures was investigated in typically developing children (aged 4 to 6 years). The effect of posture was also compared across conditions in which children did, or did not, have visual information about current hand posture. All children, including the 4‐year‐olds, demonstrated the crossed‐hands deficit when they did not have sight of hand posture, suggesting that touch is located in an external reference frame by this age. In this youngest age group, when visual information about current hand posture was available, tactile localization performance was impaired specifically when the children's hands were uncrossed. We propose that this may be due to an early difficulty with integrating visual representations of the hand within the body schema. 相似文献
