Environmental uncertainty is a fact of life in today's supply chains. In this paper we develop a model of environmental uncertainty, supply chain (SC) relationship quality and SC performance. We use data from the electronics sector in Ireland to test our model. Our results provide mixed support for the model, with the moderating role of both demand and supply uncertainty being supported, but technological uncertainty not supported. We reflect on these findings and suggest a research agenda based on our results. 相似文献

Objective:The objective for the research was to evaluate the direct healthcare costs for Crohn’s disease (CD) patients categorized by adherence status.Methods:Adult patients with ≥1 claim for infliximab and ≥2 claims for CD who were continuously insured for 12 months before and after their first infliximab infusion (index date) were identified in a 2006–2009 US managed care database. Patients were excluded if they had rheumatoid arthritis claims, received infliximab billed as a pharmacy benefit, or received another biologic drug. Patients were categorized as being either adherent or intermittently adherent to infliximab using a pre-defined algorithm. Total and component direct costs, CD-related costs, rates of surgery, and days of hospitalization were estimated for the 360-day post-index period. Propensity weighted generalized linear models were used to adjust the cost estimates for potential confounding variables.Results:The total propensity weighted cost for infliximab adherent patients was $40,425 (95% CI?=?[$38,686, $42,242]), compared to $41,082 (95% CI?=?[$38,163, $44,223]) for the intermittently adherent (p?=?0.71). However, adherent patients had lower total direct medical costs, exclusive of infliximab, that were $13,097 (95% CI?=?[$12,141, $14,127]) compared with $20,068 (95% CI?=?[$17,676, $22,784]) for intermittently adherent patients as a result of substantially lower hospital and outpatient costs (p?0.0001).Conclusions:Greater drug-related costs for infliximab adherent patients were offset by lower costs from hospitalization and outpatient visits. These findings indicate that adherent patients have improved clinical outcomes, at a similar aggregate cost, than patients who are only intermittently adherent to therapy. 相似文献

In this study the process of retail meat price determination is depicted in the form of an inverse demand system taking into consideration the dynamic adjustments present in monthly consumption data. The general dynamic framework identifies both long run and short run effects in a systematic manner and allows direct estimation of the long run price and scale flexibilities that are consistent with theory. The empirical application based on monthly U.S. meat products data provides reasonable and promising results.The authors are senior econometrician, Department of Risk Management, TRS, American Express Co., Phoenix, and assistant professor, Department of Applied Economics, University of Minnesota, St. Paul, respectively.

Many accounting educators believe that the student learning of accounting is better facilitated over a longer period of time, rather than a shorter period of time. This study examined the results of student performance in two introductory accounting courses, comparing student performance results of four-week summer classes with the results of traditional 16-week courses. In this research, the same professor taught the spring and summer ACC 201 courses, and two other professors taught both the spring and summer ACC 211 courses. Also held constant were the lecture material, course assignment, and test content. The results of the study indicate that in general, students taking introductory accounting over four weeks fare about as well as students who take introductory accounting over a traditional 16-week period. These results have potential importance beyond accounting education and provide support to universities offering more block courses to better serve individual student needs. 相似文献

This research empirically examines the importance of knowledge management processes to operational and overall organizational performance (OPERF). Specifically, results indicate that a shared interpretation of knowledge among operational personnel mediates how knowledge is disseminated and used to design and implement a unified operational response to that knowledge. Further, results collected in a logistics operations (LO) context support a strong positive relationship between this knowledge management process and operational and organizational performance. Importantly, psychometric measures for organizational performance collected from managerial respondents were strongly correlated with secondary financial data for participating firms obtained from Compustat, thus supporting a link about operational performance and hard organizational performance data. 相似文献

This study examines the culture of a medium-sized community bank based in the Western United States. The study aims to identify the organization's culture and then measure the level of cultural cohesion that exists three years after a major cultural campaign was launched. The cultural characteristics the organization valued most highly were integrity, willingness to serve the customer and teamwork - all components of the official bank document on culture. Interestingly, the analysis uncovered some significant value differences among different employee groups and also employees and management; differences which can affect firm performance levels. The analysis also revealed that changing the culture in an organization does not necessarily lead to cultural cohesion. 相似文献

Pay dispersion has been found in prior research to negatively affect both individual and workplace performance. In this study, we examine whether the relationship between horizontal pay dispersion and firm financial performance is curvilinear in nature, with moderate levels of dispersion leading to more positive outcomes than either low or high levels. Using data from a government-sponsored survey of Korean firms, we find support for the hypothesized curvilinear relationship between pay dispersion and firm financial performance. We further find that this curvilinear relationship is moderated by firm and human resource system characteristics. Where the firm had more incumbents in the rank being examined, where pay level was higher, and where there was greater organizational investment in performance evaluation and feedback, the positive slope (within the curvilinear relationship) inverted at a higher level of dispersion. 相似文献

In the first empirical study on the topic, the authors examined the ability of investment professionals to distinguish between truthful and deceptive statements. A random sample of 154 investment professionals made judgments about a series of truthful and deceptive statements, some of which involved financial fraud. Investment professionals' lie detection accuracy was poor; participants performed no better than would be expected by chance. Accuracy in identifying lies about financial fraud was especially poor. Further, participants displayed poor metacognitive realism when assessing their own performance. The theoretical and practical implications for lie detection in the financial industry are discussed. 相似文献

This paper presents a systematic study of survey mechanisms that produce or reduce minority bias in social surveys. It extends the work of Lipps et al. (2011) who have demonstrated that, in the Swiss context, the more an ethno-national minority community differs, socio-culturally and socio-economically, from the national majority, the less it is likely to be represented in its proper proportion in the major national surveys. Minority bias furthermore has a vertical dimension: socio-economic bias against individuals from the most deprived backgrounds becomes extreme within ethno-national minority communities. Using data from the Swiss Labour Force Survey, the Swiss Household Panel, and the Swiss sample of the European Social Survey, in the present work we empirically assess the impact of three types of survey practices on minority bias: (1) strategies to increase overall response rates of the whole population indiscriminately from its minority status, (2) the use of pre- and post-stratification measures that take into account the overall share of foreigners in the national population, and (3) the conduct of interviews in a wider range of languages, in order to facilitate survey response among certain (linguistic) minorities. Our findings show that efforts to increase overall response rates can, paradoxically, create even more minority bias. On the other hand, they suggest that a combination of stratified sampling and a wider range of survey languages can have a positive effect in reducing survey bias, both between and within national categories. We conclude that measures that take into account and adapt to the social and cultural heterogeneity of surveyed populations do make a difference, whereas additional efforts that only replicate existing routine practices can be counter-productive. 相似文献

This article examines the critical role that on-boarding processes play in the successful development of executive leadership talent. It is based on an in-depth case analysis of one organization's sophisticated on-boarding intervention. Specifically, we explore the potential of these interventions both to pre-empt leadership failures and to accelerate the knowledge and relationships necessary to step into an executive role. Lessons are provided on designing on-boarding interventions for senior leaders. 相似文献
