The service industry with the Educational Cooperative Suport System on employee¡¦s organizational commitment and trend of turnove

Su, Hui-Ling 27 January 2002 (has links)
This research report is focused to study of what influences of the service industry with the Educational Cooperative Suport System on employee¡¦s organizational commitment and trend of turnover. 1. What are influences of those interfering variances of characteristics (including external control character and internal control character) as well as individual variance (e.g. gender and age) on employee¡¦s organizational commitment and trend of turnover? 2. What are influences of situational interaction on employee¡¦s organizational commitment and trend of turnover? This research report is investigated within the scope of schools with 511 Model Educational Cooperative (including National Taipei Institute of business Technology, Jin Wen Institute of Technology, Van Nung Institute of Technology and Fortune Institute of Technology) and their students. Based on the expediency sampling theory, 538 (equiv. To 59.8%) out of 900 copies of the Questionnaire sent to the above-mentioned four schools, were received. Deducted from those blank and/or incomplete ones, 226 copies are effective (42% to total replies and 25.1% to total issuance). It is found out that: 1.Main influence on those service industries with the Educational Cooperative Suport System: The more pay supporting and career plan, the more organizational commitment (including recognition and centripetal force). The more pay supporting and technical training, the less trend of turnover. 2.Influence of those interfering variances of characteristics and individual variance: Based on analysis of regression, it is verified that to those employees with low external control character, the more pay supporting and career plan, the more organizational commitment (including recognition and centripetal force). To those senior employees, the more pay supporting, the less trend of turnover. 3.Influences of situational interaction: 1.1 Recognition to the organization 1.1.1 With interaction of the ¡§Educational Cooperative Suport System¡¨ and ¡§external control character¡¨, it is appeared that negative impact on ¡§pay supporting¡¨ and ¡§external control character ¡¨ (b=¡Ð0.04, p<0.05). 1.1.2 With interaction of the ¡§Educational Cooperative Suport System¡¨ and ¡§internal control character¡¨, positive impact upon ¡§career plan¡¨ and ¡§internals control character¡¨ (b=0.03, p<0.1) were found out. 1.1.3 With interaction of the ¡§Educational Cooperative Suport System ¡¨ and ¡§internal control character¡¨, there was positive impact on ¡§pay supporting¡¨ and ¡§internal control character¡¨ (b=0.06, p<0.1). 1.2 Centripetal force to the organization: With interaction of the ¡§Educational Cooperative Suport System¡¨ and ¡§internal control character¡¨, it is appeared that negative impact upon ¡§technical training¡¨ and ¡§internal control character¡¨ (b=-0.04, p<0.1). 1.3 Trend of resignation: With interaction of the ¡§Educational Cooperative Suport System¡¨ and ¡§external control character¡¨, a negative impact on ¡§career plan¡¨ and ¡§internal control character¡¨ (b=-0.04, p<0.1) was found out.

Workforce Flexibility and Organizational Performance of the Subcontractors in the Steel Industry--the Example of China Steel Co's Cooperative Subcontracting System

Yang, Mei-chi 26 August 2002 (has links)
As various forces rendering the business environment more dynamic, organizations nowadays must rapidly correspond to changes in order to survive and prosper. Observing the flexible use of manpower, Atkinson (1987) proposed the flexible firm model and attempted to draw clear demarcation among core, peripheral and external workforces. Such flexible deployment of different workforces are not uncommon in the cooperative subcontracting system in Taiwan¡¦s steel industry (Chang, 2001). In his exploratory research, Chang (2001) discusses the deployment of different workforces in the cooperative subcontracting system, however, the discussion of the relationship between workforce flexibility and organizational performance is neglected. In order to provide a more complete understanding of workforce flexibility, it is important to conduct further research. Hence, this research intends to continue Chang¡¦s research and collect more data to analyze the relationship between workforce flexibility and organizational performance among the China Steel Co.¡¦s subcontractor. Among 183 questionnaires distributed, 118 were collected and 108 were considered effective. The return rate is 59.02%. Analyzing the data, the research discover the following findings: (1) Significant differences on functional flexibility were found among different organizational traits. It is found that subcontractors with more than 3 divisions rated themselves better on the Development of Multi-skill than subcontractors with 3 divisions. (2) Significant differences on numerical flexibility were found among different organizational traits. Subcontractors with capital over 80 million dollars outsource more than subcontractors with capital under 20 million dollars. Engineering subcontractors outsource more than labor subcontractors. (3) Significant differences on wage flexibility were found among different organizational traits. Subcontractors with 60-80% dependence on CSC have more flexible wage design than subcontractors with 20-40%. (4) Significant differences on subjective organizational performance were found among different organizational traits. Subcontractors with capital over 80 million dollars were rated higher on the operational performance than subcontractors with capital under 20 million dollars. Labor subcontractors and cleaning subcontractors were rated higher on production performance more than labor subcontractors. Significant difference on production performance was also found among subcontractor of different numbers of division. Significant difference on customer satisfaction was found among subcontractors of different degree of dependence on CSC and different sizes of capital. Labor and cleaning subcontractors rated higher than engineering subcontractors. (5) Significant differences on objective organizational performance were found concerning organizational traits. Subcontractor of 60-80% dependence on CSC have higher turnover rate than subcontractors of 0-20% dependence. (6) Functional flexibility has significant positive influence on organization performance. Horizontal and vertical transfer has significant positive influence on operation performance and production performance. The development of multi-skill has significant positive influence on production performance. (7) Numerical flexibility has significant influence on organization performance. The higher the proportion of temporary workers, the lower the operation performance. The higher the proportion of temporary workers, the higher the turnover rate. (8) Wage flexibility has significant influence on organizational performance. Flexible wage design has negative significant influence on operational performance and customer satisfaction. Variable wage ratio has positive significant influence on customer satisfaction. Thus far, it is suggested that the cooperative subcontractor can (1) continue enhance measures that promote functional flexibility, (2) consider the skill difference when promoting functional flexibility, (3) hire cooperative skilled engineers or technicians for core workers, (4) implement training programs to help core workers develop multi-skills, (5) analyze business trends and maintain suitable ratio of contingent workers, (6) pay attention to legal issues regarding contingent workers, (7) consider the use of temporary help service (THS) as the substitution of hiring temporary worker by the company itself, (8) carefully evaluate the influence of wage flexibility.

Cooperative self-localization in a multi-robot-no-landmark scenario using fuzzy logic

Sinha, Dhirendra Kumar 17 February 2005 (has links)
In this thesis, we develop a method using fuzzy logic to do cooperative localization. In a group of robots, at a given instant, each robot gives crisp pose estimates for all the other robots. These crisp pose values are converted to fuzzy membership functions based on various physical factors like acceleration of the robot and distance of separation of the two robots. For a given robot, all these fuzzy estimates are taken and fused together using fuzzy fusion techniques to calculate a possibility distribution function of the pose values. Finally, these possibility distributions are defuzzified using fuzzy techniques to find a crisp pose value for each robot. A MATLAB code is written to simulate this fuzzy logic algorithm. A Kalman filter approach is also implemented and then the results are compared qualitatively and quantitatively.

Development and initial assessment of Texas Cooperative Extension's white-tailed dear management module

Bedgood, Mark Andrew 17 February 2005 (has links)
The purpose of this study was to evaluate the development and initial use of Texas Cooperative Extension’s (TCE) White-tailed Deer Management Module (WDMM) delivered over the Internet. The results of this study will provide suggestions about future online wildlife management modules. Data were collected from two populations using questionnaires. A sample of six county Extension agents (CEA’s) and four Extension specialists were selected by an Extension wildlife specialist who perceived them to be professionals in the fields of wildlife and range management. This first sample is also referred to as change agents. The second sample, also known as early users, consisted of 27 anonymous CEA’s and landowners within TCE’s District 10. Quantitative and qualitative methods were used to collect and analyze data. The results are as follows: Thus, the development of WDMM was the responsibility of the Extension specialist and researcher. The Extension specialist and researcher did seek professional opinions on content and layout information. Results suggested that CEA’s and Extension specialists agreed the WDMM would be a beneficial educational tool for new landowners. Overall, WDMM was perceived to be user friendly, visually appealing, and provided useful content. Although most change agents responded positively to most questions, there were a few that would like to see more educationally challenging questions. For example, there were a few questions that respondents felt were of the “elementary” and “kindergarten” level. They would like more questions concerning management. The majority of early users were in support of WDMM. Data gathered from the WDMM Feedback Questionnaire agreed with data gathered from change agents. In general, most early users said that they were pleased with the WDMM. Recommendations were made based on these findings to expand the WDMM. Some of these include: 1) Expanding WDMM; 2) Replicating this study using random sampling; 3) Collecting computer knowledge and skills and demographics on future studies; 4) Developing similar modules to see if they gain the same positive response.

Dynamical formulations and control of an automatic retargeting system

Sovinsky, Michael Charles 25 April 2007 (has links)
The Poincare equations, also known as Lagrange's equations in quasi coordinates, are revisited with special attention focused on a diagonal form. The diagonal form stems from a special choice of quasi velocities that were first introduced by Georg Hamel nearly a century ago. The form has been largely ignored because the quasi velocities create so-called Hamel coefficients that appear in the governing equations and are based on the partial derivative of the mass matrix factorization. Consequently, closed-form expressions for the Hamel coefficients can be difficult to obtain and relying on finite-dimensional, numerical methods are unattractive. In this thesis we use a newly developed operator overloading technique to automatically generate the Hamel coefficients through exact partial differentiation together with numerical evaluation. The equations can then be numerically integrated for system simulation. These special Poincare equations are called the Hamel Form and their usefulness in dynamic modeling and control is investigated. Coordinated control algorithms for an automatic retargeting system are developed in an attempt to protect an area against direct assaults. The scenario is for a few weapon systems to suddenly be faced with many hostile targets appearing together. The weapon systems must decide which weapon system will attack which target and in whatever order deemed sufficient to defend the protected area. This must be performed in a real-time environment, where every second is crucial. Four different control methods in this thesis are developed. They are tested against each other in computer simulations to determine the survivability and thought process of the control algorithms. An auction based control algorithm finding targets of opportunity achieved the best results.

Traditionally, customers of the airline and travel agent service industries only interacted with the agents at the travel office. The internet travel services have taken off rapidly. This industry is becoming very large for the suppliers, employees, sales and final users and this is going to be the main method for travel services. Corporate partners working together can cover the production disadvantages. My travel and airline research focuses on the co-opetition relationship. Airline websites and travel websites working together can develop a strength in online transactions. Developing a strategy together results in a huge economic effect. My research methods use my travel service company, Comfort Travel Services (Cola Tours), as an example. I spoke to a variety of Taiwanese airline managers to find out how we can work together. Through analysis we can plan production and plan sales and hope to make a bright future. The conclusions from my research are as follows: 1.Airlines rely on travel agencies for more than 90% of its business. This is a big example of corporate partners working together. 2.Travel services should diversify its internet services to more easily satisfy the customers¡¦ needs. 3.Travel agent websites serve the purpose of promoting and strengthening the skills of the agents which increases the volume of business 4.Electronic commerce relationships can be used for prosperous growth. 5.Airlines B2B can help travel agents in smoothing the flow of travel business and business standardization. 6.Direct flights to China bring a new business opportunity and further co-opetition relationships should be explored. 7.Market changes, combined with useful and positive planning, personal development and positive cycles achieve resource sharing and creates bilateral development of each brand.

Cooperative Location Update in Wireless Mobile Networks

Ye, Cai-Fang 06 August 2008 (has links)
In this paper, in order to reduce the location update cost in wireless mobile networks, we propose a cooperative location update scheme. The proposed scheme first discovers the statistical relation between mobile stations according to their history of location update and paging. In order to reduce the total cost of mobility management, we propose integrating the cooperative location update scheme with the concurrent search scheme. We use analytical results and simulation results to justify the usage of the proposed approach.

Joint Distributed Detection and Estimation for Cooperative Communication in Cluster-Based Networks

Pu, Jyun-Wei 11 August 2008 (has links)
In this thesis, a new scheme based on the concept of compress-and-forward (CF) technique has been proposed. And expectation maximization (EM) algorithm is utilized to attain the aim of converging to a local optimum solution. According to the characteristic of EM algorithm, destination node would feed back a better decision to the relay node to be the next initial value. After the iteration, relay node would obtain a better detection result which would converge to a local optimum performance. At last the destination node would receive the optimum detection result from each relay and make a final decision. In the new structure, channel estimation can also be made at the relay node by EM algorithm, which is the reason why it is called joint distributed detection and estimation. Simulation shows that the proposed scheme would acquire an iteration gain at both the relay and destination node.

If the market of military procurement conforms to the double auction (Chatterjee and Samuelson, 1983), the government and the manufacturer can try to reach a binding agreement and maximize the monopoly profit. When they both comply with the agreement, the game constitutes a cooperative game. The government and the firm can extend the periods of the game from one to two through signing the research and development contract. When they carry out the research and development contract in the second phase, the trading probability in the first phase that is double auction model will rise. However the R&D contract causes an increase of transaction probability, the market offers an opportunity let the ineligible manufacturer participate in the defense procurement. We can find the trade-off relationship between the advancement of trading probability and the appearances of unqualified firm. The result is consistent with Inefficiency theorem that an incentive-compatible mechanism which is ex post efficient will not be individual theorem.
