METHODS: A survey of 3462 employees was conducted to generate responses to Sexton's Safety Attitudes Questionnaire(SAQ) to assess perceptions of work environment via a series of five-point, Likert-scaled questions. Path analysis was performed, using teamwork(TW) and collaboration(CO) as endogenous variables. The exogenous variables are effective communication(EC), safety culture(SC), job satisfaction(JS), work pressure(PR), and work climate(WC). The measure-ment instruments for the variables or summated subscales are presented. Reliability of each sub-scale are calculated. Alpha Cronbach coefficients are relatively strong: TW(0.81), CO(0.76), EC(0.70), SC(0.83), JS(0.91), WP(0.85), and WC(0.78). Confirmatory factor analysis was performed for each of these constructs. RESULTS: Path analysis enables to identify statistically significant predictors of two endogenous variables, teamwork and intra-organizational collaboration. Significant amounts of variance in perceived teamwork(R2 = 0.59) and in collaboration(R2 = 0.75) are accounted for by the predictor variables. In the initial model, safety culture is the most important predictor of perceived teamwork, with a β weight of 0.51, and work climate is the most significant predictor of collaboration, with a β weight of 0.84. After eliminating statistically insignificant causal paths and allowing correlated predictors1, the revised model shows that work climate is the only predictor positively influencing both teamwork(β = 0.26) and collaboration(β = 0.88). A relatively weak positive(β = 0.14) but statistically significant relationship exists between teamwork and collaboration when the effects of other predictors are simultaneously controlled.CONCLUSION: Hospital executives who are interested in improving collaboration should assess the work climate to ensure that employees are operating in a setting conducive to intra-organizational collaboration.展开更多

Several studies have reported the negative effect of physician burnout and the adverse effect it has on the individual and health institutions. This study therefore examined the moderating effect of perceived organizational support on the relationship between teamwork and physician burnout in the Chinese context. Using a survey data consisting of a sample of physicians from hospitals within the Jiangsu Province of China, we estimated three models in a hierarchical framework and identified that in the presence of respondent’s demographic characteristics as control variables, perceived organizational support, play a very vital role in improving teamwork while reducing burnout among physicians.展开更多

We explore in this paper how an asynchronous ICT, called ThinkTank, reshaped the work practice of design-construction global teams, and how the interaction with this ICT reshaped the purpose and benefits of its use. ThinkTank is a web-based asynchronous collaboration and discussion forum. We introduce the influence diffusion model (IDM) that formalizes the process of identifying the influence of people, messages, and terms mathematically. Discovering who the influence leaders in project teams are can be beneficial and critical from a corporate management perspective, since they can guide or motivate the team towards successful actions and outcomes. We present the ThinkTank-IDM integrated system and its validation with a testbed of 53 AEC global team project archived in ThinkTank over 8 years.展开更多

In the fast-developing modern world, various tools are available to evaluate the track record, or publication profile of a scientist. Pursuits to achieve research results that are published in the highest impact factor （IF） journals has often become the aim of the ＂game＂, Consequently, manipulating publications to obtain higher impact factors has also become the aim of game in some journals.

When adapting a workflow process definition to specific needs or changing the structure of the workflow process as a result of evolutionary change, coarse-grained reuse of work- flow is of significance to the reduction of the work effort, modeling system and enhancing the reliability of their work. Based on decomposition of workflow tasks and teamwork, this paper proposes an approach to describing interoperability behavior between roles in teamwork by using activity-pattern. In activity-pattern, abstract mechanisms of activity specialization and activity aggregation are presented, enabling reuse of workflow by means of reuse of interoperability behavior between roles. The experimental system shows that our approach presented is feasible.展开更多
