The Dissimilar Effects of Fairness on Knowledge Sharing in Distributed Workgroups: A Social Network Perspective

Distributed workgroups are increasingly adopted by global organizations, enabled by technology advances. While social ties and performance of such workgroups have been examined in existing literature, the distinctions in knowledge sharing practices remain blurred. We developed a research model to examine the effects of social ties on knowledge sharing practices through the lens of justice perceptions (i.e., fairness) from a dyadic level. The model was tested in a field study of distributed workgroups at a large multinational organization. Our results suggested that Simmelian-tied dyads (dyads embedded in three-person cliques) had significant influence on justice perceptions and knowledge sharing. Expertise knowledge sharing was influenced by procedural and informational justice perceptions. Contrary to previous studies, our study suggested that product knowledge sharing occurred regardless of distributive justice perception. The findings provided insights to the mechanisms underlying social ties, justice perceptions, and knowledge sharing

Selection Determinants In Education Major Graduates Occupations

Taiwan’s teacher training system currently faces a serious disorder. The excessive number of teacher education programs being set up in universities by the Ministry of Education has dramatically increased the number of teachers. The situation, coupled with the country of low birth rate and high retirement age, brings about fewer teaching vacancies than the number of available teachers. The over-expansion of universities has resulted in a situation that almost every secondary school graduate can access higher education institutions, which subsequently produce a great number of graduates, far exceeding the vacancies in the workplace. This plus with the recent economic recession intensifies competition among individuals hunting for jobs. Thus, it is imperative to identify the ideal jobs for graduates, and the first step is figuring out the main determinants for selecting jobs and the relative importance of these determinants. A self-developed questionnaire was administered to 200 education major graduates in Taiwan. The result indicated that high job stability was perceived to be the most important factor among participants. Also, the education students considered school teacher or administrator to be the ideal jobs

Self-Supervised Ensemble Learning: A Universal Method for Phase Transition Classification of Many-Body Systems

We develop a self-supervised ensemble learning (SSEL) method to accurately classify distinct types of phase transitions by analyzing the fluctuation properties of machine learning outputs. Employing the 2D Potts model and the 2D Clock model as benchmarks, we demonstrate the capability of SSEL in discerning first-order, second-order, and Berezinskii-Kosterlitz-Thouless transitions, using in-situ spin configurations as the input features. Furthermore, we show that the SSEL approach can also be applied to investigate quantum phase transitions in 1D Ising and 1D XXZ models upon incorporating quantum sampling. We argue that the SSEL model simulates a special state function with higher-order correlations between physical quantities, and hence provides richer information than previous machine learning methods. Consequently, our SSEL method can be generally applied to the identification/classification of phase transitions even without explicit knowledge of the underlying theoretical models

Enhancing The Quality Of University Career Services In Taiwan: Perceptions Of University Alumni

An adequate supply of a high quality labor force is crucial for national economic and social well-being; consequently, nations worldwide have placed significant emphasis on university graduate employability. Nonetheless, in Taiwan, a mismatch between knowledge acquired in universities and competences required by the job market has dramatically encumbered the supply of a high quality labor force. Thus, this research endeavored to determine the major career services that should be offered in higher educational institutions to alleviate the aforementioned human resource problems.The analytic hierarchy process was adopted as the major instrument for calculating the relative importance of each career service task, and 169 university alumni working in four major career fields participated in this research. The results indicated that participants from different career fields and who graduated from different colleges at different times have very different opinions of job service requests; therefore, universities should seriously consider the differences among students and provide the necessary services for each student in line with his/her particular requests. Moreover, although almost all participants agreed that sharpening students’ job-search and interview skills was crucial in assisting students to find their first jobs, this service was extremely insufficient in universities, and universities thus have to place particular emphasis on this task in the future

Effects of System Characteristics on Adopting Web-Based Advanced Traveller Information System: Evidence from Taiwan

This study proposes a behavioural intention model that integrates information quality, response time, and system accessibility into the original technology acceptance model (TAM) to investigate whether system characteristics affect the adoption of Web-based advanced traveller information systems (ATIS). This study empirically tests the proposed model using data collected from an online survey of Web-based advanced traveller information system users. Con­firmatory factor analysis (CFA) was performed to examine the reliability and validity of the measurement model, and structural equation modelling (SEM) was used to evaluate the structural model. The results indicate that three system characteristics had indirect effects on the intention to use through perceived usefulness, perceived ease of use, and attitude toward using. Information quality was the most im­portant system characteristic factor, followed by response time and system accessibility. This study presents implica­tions for practitioners and researchers, and suggests direc­tions for future research.</p

Development of a DSS to Estimate the Sales for the Retailing Industry in Taiwan

An algorithm is constructed in this study to estimate the market sizes of daily commodity in Taiwan based on the sampled sales information provided by retailer chains. Though retailer chains provide sampled sales information from only small portions of their retailing stores, they expect to receive more valuable processed information from that. As result of this research, a DSS is proposed to compute value-added information from this joint sales information database, namely the estimation information. Through certain public accessible data such number of stores by each chain and retailers’ financial reports, the sampled sales information can be transferred to the market size information of each item in Taiwan. Two similar algorithms are constructed for convenient stores and supermarkets/hypermarkets separately. A simple integration method is used to combine these results. Finally, a DSS is built based on these estimation algorithms and is implemented successfull

The relationship between velocity utilization rate and pole vault performance

In the pole vault event, the velocity of approach is a highly vital factor. As velocity of approach improvements highly impact performance improvements. This study analysed the relationships between sprint running’s speed (SR), pole running (PR, without jump), and the pole vault approach (PVA, with real jump). Analysed too were the relationships between both the approach and performance’s respective running distance, velocity, and velocity utilization rates. Methods: Ten male pole vaulters were recruited. Measured was each 5-meter segment’s average velocity of his respective SR, PR, and PVA, along with the distance to maximum velocity. Results: The maximum average velocity of the PR’s 5m segments altogether was significantly positively correlated with pole vault (PV) performance; The maximum average velocity of the PR’s 5m segments altogether was significantly positively correlated with the last 5m PVA average velocity; The PVA velocity’s utilization rate was significantly negatively correlated with the difference between the distance to the PR’s maximum velocity and the PVA’s distance. Conclusion: The PR segment’s maximum speed capability can evaluate both a pole vaulter’s potential and pole vault-specific abilities. This study’s recruited pole vaulters’ respective approach distances were generally insufficient that resulted in a lower velocity utilization rate. Suggested is that in training, the pole vaulter could first find the distance required to reach the highest velocity upon starting from the PR test. Thus, this subsequently known distance could be applied in tandem with the pole vault’s approach to both improve the PVA’s utilization rate and reach the individual highest speed level
