World Wide Web(WWW)is a vast repository of information,including a great deal of geographic information.But the location and retrieval of geographic information will require a significant amount of time and effort. In addition,different users usually have different views and interests in the same information. To resolve such problems,this paper first proposed a model of geographic information gathering based on multi-Agent(MA)architecture. Then based on this model,we construct a prototype system with GML(Geography Markup Language). This system consists of three tiers-Client,Web Server and Data Resource. Finally,we expatiate on the process of Web Server.  相似文献

This paper contributes to our understanding of the process of knowledge creation in organisations. Based on a process model, the paper develops propositions relating to factors facilitating knowledge creation in cross-functional work teams. These propositions relate to the constructs of cognitive diversity, transactional memory, trans-specialist knowledge and their contribution to new knowledge development through knowledge boundary spanning.  相似文献

Through the use of taped interviews, the reasoning level of eleven (11) pre-service teachers relative to selected concepts in Algebra was ascertained. Yumus’ (2001) levels of reasoning were applied as a guide, namely: (a) Level 1: Unable to produce any reasoning, (b) Level 2: Have awareness of the models, known facts, properties and relationships to be used but cannot produce any arguments; (c) Level 3: Able to produce some reasoning although the arguments are weak and (d) Level 4: Able to produce strong arguments to support their reasoning. Using this guide it was found that of the 121 responses given, 47.1% were at level 1, 29.8% at level 2, 16.5% at level 3 and only 6.6% were at level 4. The most difficult problem proved to be converting repeating decimals to fractions, while the easiest was on finding the value of x0. As a whole, the reasoning ability of the respondents, based to their average reasoning ability on the given tasks, indicate that 73% was low, 27% was moderate and that nobody had a high level of reasoning. Assessments followed as to the factors contributing to this situation and possible solutions.  相似文献

Awareness levels of individuals about various aspects of the collaborative processes can be achieved by effective promotive interactions among them. Cultural structures are regarded as one of the major determinants of knowledge sharing patterns and awareness levels of individuals in collaborative contexts. Through an exploratory review of the literature, the present study points to the two rival organisational structures of cooperation and competition that coexist in any organisation in different intensities and mixtures. Finding a desirable mix of the above two structures is currently a challenging task and no explicit method exists for determining such an ideal mix. This study provides further theoretical insights into the analysis of incompatible impacts of several factors on the awareness levels of individuals in collaborative contexts. Drawn from the findings in the current body of literature, a conceptual model is developed. The proposed model relates cooperative and competitive structures, task dimensions, and group characteristics as potential factors that determine the awareness levels of individuals. The face validity of the proposed model is checked by employing an expert focus group. As a result, a number of enhancements and improvements to the model are proposed. Pragmatic aspects of the proposed model are then discussed and recommendations for future research are provided.  相似文献

The continuous use of synthetic hormones as contraceptive pill or hormonal replacement therapy among women is increasing day by day. The widespread use of different formulations as oral contraceptives by women throughout their reproductive cycle has given rise to a serious concern for studying the effects of oral contraceptives on enzymatic profile and DNA damage in peripheral blood lymphocytes among users. The present study was carried out on women taking oral contraceptives. The study was based on the questionnaire having the information of reproductive history, fasting, age, health, nature of menstrual cycle, bleeding and other disease. The profile of the blood serum enzymes i.e. alkaline phosphatase (ALP), gamma glutamyl transferase (GGT), lactate dehydrogenase (LDH), aminotransferases (SGOT and SGPT), serum proteins (albumin and globulin) and DNA damage in lymphocytes was studied among users and non-users. The results of the present study suggest that OCs not only effects enzymatic activity but also results in DNA damage that may vary with the duration of using oral contraceptives. A significant increase in LDH, GGT, SGPT, SGOT, globulin and decrease in ALP as well as albumin was found among users as compared to non-users. The observed DNA damage was more in users as compared to non-users. Hormonal contraceptives seem to exert DNA damage and also have significant effects on blood serum enzymes.  相似文献

Four large organizations, two each from the private and public sectors of the Northern Ireland economy, were selected for this study which, first, explored the effects of religion-based workforce difference on intergroup relationships, second, investigated the contribution of organizational sector to communicative differences, and third, gauged the effects of group-based negativity on the flow and distribution of functional information within the organization. Little evidence of intergroup conflict was found although employees expressed a desire for greater quantity and quality of outgroup contact. Significant differences between the private and public bodies emerged in this respect. Contrasts were consistent with general organizational differences typifying the sectors. Findings are discussed in relation to diversity management and the characteristics of organizational sectors.  相似文献

Prematurity and low birth weight (LBW) are two major biological factors that put infants and young children at high risk for developmental delays or disabilities. While survival rates for premature and LBW children have improved, incidence figures have changed little over the past 20 years; in fact, the incidence of LBW has increased. Although the vast majority of LBW children have normal outcomes, as a group, they have higher risk for subnormal growth, illnesses, and neurodevelopmental problems. The purpose of this article is to examine the factors that influence the effectiveness of early intervention for premature, LBW children and to describe a strategy for linking assessment and early intervention. Linking assessment and intervention involves comprehensive assessment; a team approach to both assessment and intervention; empowering and enabling families; and the development of functional goals and objectives.  相似文献

The semiconductor industry has made great contributions to Taiwan’s economy in the past 20 years. Because of competitive salaries and generous fringe benefits, some famous semiconductor manufacturers have become the best choice for students right after graduation. However, such magnetic effect has gradually faded away in the face of implementation of expensive employee bonuses. In a changeable environment, sharing knowledge will maintain organizational competitiveness and improve employees’ cohesion. As the semiconductor industry is characterized by a low-wage and high-turnover rate, the incurred job insecurities and career uncertainties have begun to force employees to change their cohesion, loyalty to organizations and even to reduce their willingness to share knowledge with others. This study aims to explore the relationships among organizational commitment (OC), knowledge sharing (KS) and organizational citizenship behavior (OCB) in the Taiwanese semiconductor industry. On the basis of 428 subjects, the results show that KS has a partial mediating effect on the OC–OCB relationship.  相似文献
