Background Operating room (OR) managers seeking to maximize labor productivity in their OR suite may attempt to reduce day-today variability in hours of OR time for which there are staff but for which there are no cases ("underutilized time"). The authors developed a method to analyze data from surgical services information systems to evaluate which management interventions can most effectively decrease variability in underutilized time. Methods The method uses seven summary statistics of daily workload in a surgical suite: daily allocated hours of OR time, estimated hours of elective cases, actual hours of elective cases, estimated hours of add-on cases, actual hours of add-on cases, hours of turnover time, and hours of underutilized time. Simultaneous linear statistical equations (a structural equation model) specify the relationship among these variables. Estimated coefficients are used in Monte Carlo simulations. Results The authors applied the analysis they developed to two OR suites: a tertiary care hospital's suite and an ambulatory surgery center. At both suites, the most effective strategy to decrease variability in underutilized OR time was to choose optimally the day on which to do each elective case so as to best fill the allocated hours. Eliminating all (1) errors in predicting how long elective or add-on cases would last, (2) variability in turnover or delays between cases, or (3) day-to-day variation in hours of add-on cases would have a small effect. Conclusions This method can be used for decision support to determine how to decrease variability in underutilized OR time.

Reactions To Feedback

This paper focuses on explaining how individuals set goals on multiple performance episodes, in the context of performance feedback comparing their performance on each episode with their respective goal. The proposed model was tested through a longitudinal study of 493 university students’ actual goals and performance on business school exams. Results of a structural equation model supported the proposed conceptual model in which self-efficacy and emotional reactions to feedback mediate the relationship between feedback and subsequent goals. In addition, as expected, participants’ standing on a dispositional measure of behavioral inhibition influenced the strength of their emotional reactions to negative feedback.

The Relationship

This study focused on college students’ attitudes toward the relationship between online civic responsibility and online civic engagement and its impacts. It also investigated the mediating roles of online civic learning and online civic expression in this relationship. A survey was conducted in Taiwan, testing for indirect effects with mediated variables using a structural equation model. The study tested hypotheses about the mediations of online civic learning and online civic expression on this relationship between online civic responsibility and online civic engagement for college students. The results indicate that the mediators of online civic learning and online civic expression fully mediate the relationship between online civic responsibility and online civic engagement.

The Uk

<p>Peatlands are globally valued for the ecosystem services they deliver, including water quality regulation and carbon sequestration. In the UK, blanket bogs are the main peatland habitat and previous work has linked blanket bog management, especially rotational burning of heather vegetation on grousemoors, to impacts on these ecosystem services. However, we still lack a mechanistic, process-level understanding of how peatland management and habitat status is linked to ecosystem service provision, which is mostly driven by soil microbial processes.</p><p>Here we examine bacterial and fungal communities across a spectrum of “intact” to degraded UK blanket bogs and under different vegetation management strategies. Sites included grousemoors under burnt and alternative mown or uncut management along with further locations including 'near intact', degraded and restored sites across a UK climatic gradient ranging from Exmoor (South UK), the Peak District (Mid) to the Flow Country (North). Moreover, an experiment was setup at the University of York with peat mesocosms taken from all sites and management/habitat conditions to allow a comparison between field and controlled conditions and assessing root-mediated processes. Using a structural equation model, we linked grousemoor management to specific fungal/bacterial functional groups, and have started to relate this to changes in water quality provision and carbon cycle aspects. This represents a significant step in the effort to use microbial communities as indicators of peatland habitat condition in UK upland blanket bogs. </p><p> </p>

The Relationship

This study examined the impact of E-CRM on customer loyalty with the mediating effect of customer satisfaction in the banking industry. Customer satisfaction is important for loyalty because when the customers are satisfied with the services offered by their service providers, the relationship gets stronger which further leads to positive word-of-mouth. The data was collected using purposive sampling from 836 banks’ customers who were using E-CRM services and the data was analyzed using structural equation model (SEM) through AMOS. The results revealed that E-CRM and customer satisfaction had a significant positive impact on customer loyalty and also customer satisfaction partially mediated the relationship between E-CRM and customer loyalty. This study would offer useful acumen to both academicians and marketers and would help the bank managers to improve the quality of the services provided to their customers.

During the new normal era after pandemic Covid-19, the tourism destination needs to struggle and adapt for recovery. This process requires optimal human resource performance. The objective of this study is to examine the model of human resource performance in tourism destination after pandemic. Leadership, motivation, and organizational commitment are consider as the antecedents of human resource performance. This study implements a quantitative approach. The data collection method used a questionnaire that distributed to 105 employees in Balkondes as respondent. The data analysis method used Structural Equation Model (SEM) with AMOS. The results show that leadership, motivation, and organizational commitment have a positive and significant effect on human resource performance. The results also show that organizational commitment has mediating effect on the relationship between leadership toward human resource performance, and motivation toward human resource performance.

AbstractThis study examines the effect of perceived organisational politics on organisational silence through the mediating role of organisational cynicism. In addition, it tests the effect of perceived support on this relationship. A quantitative (questionnaire survey) design was used to gather data from 346 employees in three public hospitals in Iraq. The structural equation model was used for data analysis. The results demonstrate that all the major hypotheses were accepted, and important role of perceived support in reversing the positive relationship between perceived organisational politics and organisational cynicism was also highlighted. Furthermore, the mediating role was clear in terms of organisational cynicism and the relationship between perceived organisational politics and organisational silence.
