Objectives: Harmonic devices have become a world-wide standard for dissection and hemostasis in thyroidectomy. Numerous systematic reviews have reported superior operating times, blood loss, post-operative pain, length of stay, and overall safety outcomes. What has not been extensively evaluated in a robust manner is their economic impact. The purpose of this study is to evaluate the hospital costs associated with open thyroidectomy using Harmonic devices compared with conventional techniques for hemostasis. Methods: A systematic review of Medline, Scopus, and CENTRAL was performed from January 1, 2000 to May 23, 2014 without language restrictions for randomized clinical trials comparing Harmonic surgical devices to conventional methods in thyroidectomy. The main outcome measure was total reported costs. Costs were pooled using the ratio of means and a random effects model. Sensitivity analyses assessed whether differences in patient and trial characteristics, healthcare setting, or choice of statistical model affected outcomes. Results: Seven studies met the inclusion criteria. A total of 476 participants had procedures performed with Harmonic devices and 478 with conventional monopolar electrosurgery and clamp, cut and tie techniques. Compared with conventional techniques, Harmonic devices reduced total reported costs by 10% (p?=?0.007), resulting in a $229?US dollars (USD) absolute reduction from mean baseline costs. Results remained relatively robust to additional sensitivity analyses. Conclusions: This systematic review and meta-analysis demonstrates that the Harmonic family of surgical devices is associated with a reduction in total reported costs in thyroidectomy compared with conventional techniques. A large portion of the overall savings derives from a reduction in operative costs. 相似文献

This paper presents a theoretical framework analysing the signalling channel of exchange rate interventions as an informational trigger. We develop an implicit target zone framework with learning in order to model the signalling channel. The theoretical premise of the model is that interventions convey signals that communicate information about the exchange rate objectives of the central bank. The model is used to analyse the impact of Japanese FX interventions during the period 1999–2011 on the yen/US dollar dynamics. 相似文献

We provide empirical tests of a general version of targeting theory that greater scrutiny could lead to executive abuses. Our results show that new CEOs under higher expectations or pressure are more likely to report meeting analyst forecasts; however, this apparent superior performance dissipates after excluding firms having characteristics synonymous with earnings manipulation. We find evidence that new CEOs under greater pressure are considerably more likely to engage in manipulation while the link between expectations and manipulation is much weaker. The results are strongest for new CEOs whose firms report meeting forecasts and do not “walk down” earnings estimates. 相似文献

In this article, we provide a comparative account of the evolution of private saving in India and Malaysia, and analyze how
policy changes in the financial sector and pension system help explain differences in their saving performance. Using the
Autoregressive Distributed Lag (ARDL) bounds estimation procedure, we find a fairly robust long-run relationship between private
saving and its determinants in both countries. Consistent with the predictions made in the life cycle model, our results indicate
that higher income growth stimulates private saving and an increase in age dependency retards private saving. The results
provide some support for the hypothesis that financial liberalization results in lower private saving in both countries. The
evidence also indicates that expected pension benefits tend to stimulate private saving in India, but that the reverse is
found in Malaysia. 相似文献

Since its genesis over twenty years ago, research in International Entrepreneurship has emerged as a field of study, and moved through the process of differentiation, mobilization and legitimacy building. Generally referred to as IE, research in this area is conducted by scholars worldwide and supported by various community structures, conferences and journals. In recognition of IE, this Special Forum was initiated to help clarify its parameters and history of development, the areas of research pertinent to it and critically, directions for future research. 相似文献

Distance functions are increasingly being augmented, with environmental goods treated as conventional outputs. A common approach to evaluate the opportunity cost of providing an environmental good is the exploitation of the distance function's dual relationship to the value function. This implies that the opportunity cost is assumed to be non‐negative. This approach also requires a convex technology set. Focusing on crop diversification for a balanced sample of 44 cereal farms in the East of England for the years 2007–2013, this paper develops a novel opportunity cost measure that does not depend on these strong assumptions. We find that the opportunity cost of crop diversification is negative for most farms. 相似文献

This article examines how children collectively appropriate brands as cultural resources. From the New Childhood Studies perspective, an ethnographic study was conducted in schools to investigate the engagement of 10- to 11-year-old children in brand culture. The findings demonstrate that, through a process similar to Corsaro’s model of interpretive reproduction, children do not simply reproduce brand culture; instead, they actively use branding to fuel their peer culture. Mastering and manipulating brands are thus sources for integration or exclusion within the peer group and for differentiation from the adult world. We show the paradoxical impacts of branding on children’s well-being and participate in the debate on their vulnerability to marketing by highlighting how they deploy brand culture to interact in their social spheres, with the consequence being that their would-be empowerment remains entangled in the “brandscape.” Last, we contribute to a better understanding of the concept of culturally based brand literacy. 相似文献
