Two experiments were carried out to investigate contributions of voluntary manual exploration and vision to rod-bisection performance when the rod was placed in different spatial positions. Analysis showed both voluntary manual exploration and vision contributed to the accuracy of rod-bisection performance in healthy adults (Exp. 1: 12 men, 13 women; Exp. 2: 10 men, 11 women). Advantages of voluntary manual exploration were related to rod position and initial search direction. Results are discussed with regard to ecological approach to action and perception, two cortical systems (ventral and dorsal streams) for perception and control of actions, and the hemispheric activation hypothesis. 相似文献

Knowledge sharing has become a legitimate and important organizational activity. Over the last two decades, firms have become
creative in their efforts to make knowledge sharing take place. Meanwhile, Machiavellian orientation has been regarded as
one of the most important variables in the study of management and organizational behavior for the last three decades. However,
the existing literature does not offer any measure of relationships between Machiavellianism and knowledge sharing willingness.
Therefore, this research aims to explore the relationship between Machiavellianism and knowledge sharing willingness. With
a total of 325 valid questionnaires completed by employees, the paper presents some conclusive and valuable suggestions for
businesses and scholars alike. 相似文献

The aim was to assess the self-efficacy and health outcomes of an adopted Arthritis Self-Management Programme (ASMP) among osteoarthritic knee sufferers in Hong Kong at 1 year. An experimental study with 95 participants assigned randomly to the intervention (n=45) or control group (n=50). Seventy-seven (81.1%) participants joined at least one out of three follow-ups in the 12 month period. Participants in the intervention group received a 6-week ASMP with an added exercise component in two general clinics. Outcome measures included arthritis self-efficacy (ASE) and health outcomes including pain and fatigue rating, self-rated health, daily activities limitation and number of unplanned arthritis-related medical consultations. Mean change (12 months minus baseline) and the effect size of the outcome measures were calculated by Mann-Whitney U test and nQuery Advisor 4.0. At 12 months, there were significant reductions of current pain (p=0.0001), pain at night (p=0.001), pain during walking (p=0.01) and number of unplanned arthritis-related medical consultations (p=0.03) and a significant increase in ASE for pain (p=0.01) and other symptoms (p=0.02) and self-rated health (p=0.04) among the intervention group but not for the control group. However, there were similarities in outcome measures of pain while switching from a sitting to a standing position, fatigue rating and physical functional limitation (p=0.15; p=0.22 and p=0.91, respectively) for both groups. Our findings add to the evidence that the modified arthritis empowering programme improved perception of control of osteoarthritis and three health outcomes after 12 months of treatment. 相似文献

The purpose of the present study was to develop a magnetic resonance (MR) compatible photoplethysmograph (PPG) system that can measure the raw PPG signal during MR image acquisition. The system consists of an optic sensor that measures the optic signal, an optic cable that transmits a near-infrared optic signal, a signal amplifier, and a filter for noise removal. To minimize interactive noise, only the optic cable and the optic sensor module are located inside the MR room; the signal amplifier and filter are located outside the MR room. An experiment verified that a reliable PPG signal can be obtained without causing a deterioration in the MR image. 相似文献

By using a national representative sample (N = 11,555), the current study tested cultivation theory and aimed at understanding the relationship between medical drama watching and viewer perception and beliefs related to health. Findings suggest that heavy viewers of medical dramas tend to underestimate the gravity of chronic illnesses such as cancer and cardiovascular disease and undermine the importance of tackling these issues. Heavier viewers of medical dramas, compared to lighter viewers, also tend to take a more fatalistic perspective about cancer. Theoretical implications for cultivation theory and practical implications for health policy makers and drama producers are discussed. 相似文献

Misconceptions about psychiatric wards frequently cause newly admitted mental patients to stay away from these wards despite their need for treatment. Although ward orientation is typically conducted by nurses in an attempt to help patients to adapt to the new environment, it is considered time-consuming, and the method of orientation and the explanations given may vary among different nurses. This situation calls for a more effective and standardized approach to orientating mental patients on their first admission. To this end, a computer-based interactive virtual environment was developed based on a real psychiatric ward by using virtual reality (VR) technologies. It enables the patient to navigate around to gain understanding about the ward through a virtual guided tour. The effectiveness of this VR orientation approach was investigated by a randomized controlled trial with consecutive sampling. Fifty-four Chinese participants were randomly assigned to undergo ward orientation by either using the VR-based approach or reading text-based electronic information sheets about the ward with a computer. Subjective and objective measures were obtained respectively using the Chinese version of the State-Trait Anxiety Inventory questionnaire and the heart-rate variability measurement before and after the intervention. In addition, a test on the level of understanding about the ward was administered at the end of the session. The results showed that the VR orientation approach is helpful in reducing patients' anxiety while also improving their level of understanding about the ward. 相似文献

Neural plasticity of pitch processing mechanisms at the human brainstem, as reflected by the scalp-recorded frequency-following response (FFR) to voice pitch, has been reported for normal-hearing adults. Characteristics and maturation of such a response during the first year of life have remained unclear. The purpose of this study was to examine the characteristics of FFR to voice pitch in normal-hearing infants and to make a direct comparison with adults using the same stimulus and recording parameters. 9 infants and 9 adults were recruited. A Chinese monosyllable that mimics the English vowel /i/ with a rising pitch was used to elicit the FFR to voice pitch. The results demonstrated that infant FFRs showed slightly larger Pitch Strength but comparable Frequency Error, Slope Error, and Tracking Accuracy to those obtained from adults. Early maturation of FFRs was also observed in the infants starting from 1 to 3 mo. of age. 相似文献

This article attempts to motivate a new approach to anti-realism (or nominalism) in the philosophy of mathematics. I will
explore the strongest challenges to anti-realism, based on sympathetic interpretations of our intuitions that appear to support
realism. I will argue that the current anti-realistic philosophies have not yet met these challenges, and that is why they
cannot convince realists. Then, I will introduce a research project for a new, truly naturalistic, and completely scientific
approach to philosophy of mathematics. It belongs to anti-realism, but can meet those challenges and can perhaps convince
some realists, at least those who are also naturalists. 相似文献

Among 30 Hong Kong Chinese fourth graders, sensitivities to character and word constructions were examined in judgment tasks at each level. There were three conditions across both tasks: the real condition, consisting of either actual two-character compound Chinese words or real Chinese compound characters; the reversed condition, with either the order of the two morphemes in the word or the order of the semantic and phonetic radicals in the character reversed; and the random condition, with either two morphemes randomly combined to create arbitrary nonwords or a semantic radical and a phonetic radical randomly combined using correct orthographic rules to create noncharacters. On the word level, children performed worst in the reversed condition and best with real words, whereas on the character level, children performed worst in the random condition and best in the reversed condition. Findings imply a holistic tendency toward word-level processing and an analytic approach to character-level processing in these Chinese children. 相似文献
