The accuracy and similarity of team members' perceptions regarding the interdependencies of their task as well as the criticality of teamwork behaviors is essential to team performance. Unfortunately, these perceptions are not always accurate or similar, which has led to calls for research evaluating the effectiveness of interventions aimed at improving these perceptions. The present study evaluated the accuracy and similarity of crew members' perceptions of task interdependence and teamwork in the U.S. railroad industry. Specifically, this study assessed (1) the effect of Crew Resource Management (CRM) training on the accuracy and similarity of locomotive and maintenance of way (MOW) crew members' perceptions and (2), the extent to which the accuracy and similarity of those perceptions are retained 2-years after training. The overall results of the present study suggests that CRM training is effective in increasing the accuracy and similarity of crew members' perceptions of team-relatedness (amount of task interdependence) and perceptions regarding the importance of teamwork. However, the effectiveness is often dependent on the metric used (i.e., accuracy vs. similarity), and the specific characteristics of the crew members (i.e., locomotive vs. MOW, higher vs. lower interpositional experience). Furthermore, the results suggest that training did not increase the accuracy or similarity of crew members' perceptions of team workflow pattern (form of task interdependence). Lastly, a small sample size and low power precluded the running of quantitative statistical analysis assessing the long-term retention of the accuracy and similarity of participants' perceptions of task interdependence or teamwork. However, for the sake of completeness, the means, standard deviations, and effect sizes are presented in the Appendix.

The enterprise battlefield is estate, enterprise is among estate competitiveness manage the success or failure key. Though M. Porter brings forward competition strategy think: Enterprise will be confronted with ¡¥stuck in the middle¡¦ awkward situation if being able to not to choose from cost leadership, differentiation and focus strategy alternative. Afterwards, Porter indicates that in one book "Country Competitive Advantage ": Have a lot of enterprise indeed cost to be led with differentiation use together, and have the fine achievement effect; In other words, if cost leadership and differentiation manage to be used simultaneously, both multiply effect general stronger. In supply chain, the production logistics system must give consideration to cost, quality, deliver achievement effects such as scheduled time and safety; Except taking that cost leadership as target, field delivering customer regard such as scheduled time and safety in quality, is shown differentiation, is also that the tactics planning and management taking supply chain as the lifting competitive advantage competing for unit times middle, entire supply chain planning and management system manages a target. How will the production logistics system of modern enterprise change to adapt to the new tactics plan under give consideration to cost leadership and differentiation strategies? Study is from case study according to Task-Technology Fit Theory originally, produce what logistics management acts as role in development process of knowing the case company supplying chain in estate, manpower includes topic for discussion and method of work encountered by whose especially with information technology complementing each other; Interview studying process is middle, being to permeate a depth mainly, that discusses the collocation relevance document with the viewpoint, arrange out reference pattern of may be for estate's supplying chain construction the system producing a logistics management of having competition. Childbirth studying main observation is limited originally logistics management reality affair, the pad `produces the planning and management' pattern , hopes a modest spur to induce someone to come forward with his valuable contributions with construction, develop so-called ¡¥production logistics¡¦ theory.

With the rapid and constant changes taking place in information technology and internet, only firms participating in the creation and utilization of knowledge can hope to obtain the advantageous position in today¡¦s knowledge-based economy. Thus, the issues surrounding knowledge management (KM) have attracted more and more concern from both industry and academia. To add value with KM, we need KMS, which involve the application of IT systems and other organizational resources to manage knowledge strategically, are a relatively recent phenomenon. The goal of this research is to find the significant factors that link with KMS use and individual performance by using diamond model and contingency theory, which emphasizes the importance of fit. We combine with three distinct factors of compatibility, including (1) Technology - Task Compatibility (2) Technology - People Compatibility (3) Technology - Organization Compatibility, to mold an integrated model. An empirical survey methodology is applied to test the research model and seven hypotheses are developed in this study, and then we use PLS to analyze it. The results reveal that Technology-Task compatibility contributes most to the use of KMS. It implies that KMS should fulfill the task needs of users, and therefore, people will use more functions of the KM systems frequently. Besides, Technology-People compatibility has similar effect on the use of KMS. This suggests that it will enhance the usage if the KMS is more compatible with users¡¦ past experience and value. We also found that Technology - Organization compatibility has least impact on usage, but it still needed to take into consideration and worthy to discuss in the future research. In sum, unlike much prior research that has focused on only a limited aspect of compatibility, we provide a more comprehensive conceptual definition that disaggregates the content of compatibility into three distinct and separable constructs and the findings of this study provides some suggestions for the KMS research.

This research aims to investigate three issues :(1) how the consumer needs of pop music and the product attributes of records affect consumer satisfaction, (2) this research also focuses on how the match between the consumer needs of pop music and the product attributes of records affect consumer satisfaction, and (3) how the consumer satisfaction contributes to the repurchase intention is also discussed. Our study shows that listening to music, acquiring the information about music and adoring idols are main consumer needs. When the CD products satisfy these consumer needs, the consumer satisfaction will be high. In addition, consumers identify three major product attributes: function, idolatry and fashion. The interaction between listening to music, acquiring music information and functional attributes will affect consumer satisfaction positively. Similarly, the interaction between the idolatry and symbol of idol will affect consumer satisfaction positively. Consumer satisfaction has also been found to affect the repurchase intention. Compare to consumer needs, the perceived value of CDs has a stronger effect on consumer satisfaction. Therefore, if business models may need to be developed to reform the compact discs industry.

Over the last few years, there have been striking developments in wearable computing. Among all the different forms of wearable devices, Head Mounted Displays (HMDs) are deemed the first seamless solution to enabling workers with real time contextual information and allowing companies to integrate with existing back-end systems. The hands-free feature that come along with the HMDs is also believed a great advantage over many traditional technologies. However, few studies had discussed the impact of different design characteristics of head mounted displays on task performance. This study aimed to find out how different display positions of Head Mounted Displays may affect the performance of workers performing guided repair and maintenance tasks. A set of car maintenance tasks were performed by 20 participants with task guidance presented at four Display Conditions: above-eye HMD, eye-centered HMD, below-eye HMD and the traditional paper manual. Time and errors were measured and discussed, as well as other user experience related measurements.

Attention-deficit/hyperactivity disorder (ADHD) is one of the leading diagnoses for children. Children diagnosed with ADHD often have difficulty in many settings including at school as well as in the home. Medication is often a common treatment for these children, however, it has been often shown ineffective when used alone. A review of behavioral interventions, including various self-regulation interventions has been studied. Self-regulation interventions have been shown to be effective for children diagnosed with ADHD primarily in school or academic settings. The purpose of this study was to evaluate the effects of a self-management intervention on the on-task behavior of children diagnosed with ADHD. Specifically, this study aimed to examine the impact a self-management intervention would have on the on-task behavior of children during various routines, both academic and non-academic, in the child's home setting. Participants were trained to use a self-management intervention. As a result of the accurate use of the self-management intervention all three participant's on-task behavior increased. For one participant, the duration of the targeted routine also substantially decreased.

A considerable body of research supports the application of behavioral economic principles to study the relative reinforcing efficacy of drug and alcohol use. One self-report measure, the Alcohol Purchase Task, is thought to account for individual differences in the subjective valuation of alcohol consumption. To date, however, behavioral economic approaches have not evaluated the possible influence of memory-based expectations regarding the cognitive and behavioral effects of substance use on their measures. Alcohol expectancy research has found that more positive expectancies about the effects alcohol directly mediate drinking behavior and are associated with a number of alcohol-related outcomes. Given the importance of alcohol expectancies, the current study incorporated cognitive priming techniques into the Alcohol Purchase Task instruction set to test whether the activation of alcohol expectancy primes influenced patterns of alcohol consumption. Although previous research has primarily used the Alcohol Purchase Task in samples of heavy drinkers, we also examined differences between heavier and lighter drinkers to test whether expectancy primes would differentially influence alcohol demand. As expected, both heavier and lighter drinkers in the expectancy priming conditions purchased more alcohol overall relative to those in a non-primed condition. Results also suggest the positive-social expectancy content in the Alcohol Purchase Task increased the overall demand for alcohol relative to a modified Alcohol Purchase Task with no contextual primes, even after controlling for alcohol consumption. Although previous behavioral economic research has examined alcohol expectancies as a secondary outcome, the current study is the first to directly examine the influence of expectancies on alcohol demand using the Alcohol Purchase Task.
