Overlooked encounters: young tourists' experiences at dark sites

This research note reviews the existing literature comprised of dark tourism articles and chapters mentioning children. Publications meeting the search criteria were few. Accordingly, we offer possible reasons for the scarcity of research on children in dark tourism, including the legal constraints when researching with minors, the academic risk in undertaking a new field of research, and the substantial expertise needed to engage children in studies. We conclude with the compelling reasons to undertake such research: to inform interpretation of emotionally provocative sites for children, to understand and mitigate children's psychological distress at dark sites, and to advance theoretical work on children as tourists.     

衡量房价合理回归标准的思考

房价合理回归就是要通过对房价的调控使其回到合理水平,它体现了中央政府对房价调控的决心和信心,反映了城镇居民的心声和期待。判断房价是否合理回归,一看房价是否与城镇居民收入相适应;二看房价是否与成本和合理利润相匹配。要促进房价合理回归,必须坚持房价调控政策不动摇,巩固房价调控成果;努力降低商品住房成本,制止开发商暴利行为;理顺收入分配关系,增加城镇居民收入;加大保障性住房建设力度,构建住房保障体系;抑制住房投机需求,维护市场秩序,以实现房价调控目标。     

Multi-product costs and standby capacity derived from queuing theory: the case of Belgian hospitals

Empirical hospital cost function studies can be divided into two categories: studies estimating traditional multi-product cost functions and studies including demand uncertainty (assuming that hospitals provide standby capacity to cope with uncertain demand and stressing that the relationship between the uncertain demand, excess capacity and costs should be investigated). Most studies include (the inverse of) the occupancy rate in a relatively basic cost function. The first contribution of this paper is to incorporate an indicator of reserve capacity into a genuine multi-product cost function. The second contribution is to propose an alternative indicator to proxy the reserve margin. The often used occupancy rate has an important shortcoming: the same occupancy rate can hide different turnaway probabilities and waiting times, obscuring the true degree of reservation quality. Since turnaway probabilities and waiting times are typical queuing theory indicators, an indicator for average waiting time (derived from queuing theory) is incorporated into a proper multi-product cost function to capture the degree of standby capacity into a proper multi-product cost function. The study uses 1997 data on Belgian general care hospitals to estimate a multi-product cost function and calculate cost elasticities, marginal costs and the degree of economies of scale. The results further show that providing standby capacity has a significant impact on total costs.     

The Scholarly Status of Blacks in the Economics Profession: Have the National Economic Association and the Review of Black Political Economy Mattered?

This paper considers whether the National Economic Association and its journal the Review of Black Political Economy have enhanced the scholarly status of black economists. A bibliometric analysis reveals that while the typical black economist has never published in the Review of Black Political Economy, the share of black economists publishing in the Review of Black Economy approximates the share of all articles published on the economic and political economy of race by black economists, and the share of articles published in the Review of Black Political Economy by black economists appears higher than typical journals in economics—particularly for black economists employed at Historically Black Colleges and Universities. We also find that similar to other economics journals non-black economists dominate the share of published articles, and publications in the Review of Black Political Economy appear to be consistent with Lotka’s Law of scientific productivity suggesting that the journal is a standard outlet for research no different from any other science journal. Our results imply a plausible counterfactual that if the National Economic Association and Review of Black Political Economy did not exist, the scholarly status of blacks in the economics profession would have been lower than currently observed.     

MULTIVARIATE METHODS FOR MONITORING STRUCTURAL CHANGE

Detection of structural change is a critical empirical activity, but continuous ‘monitoring’ for changes in real time raises well‐known econometric issues that have been explored in a single series context. If multiple series co‐break then it is possible that simultaneous examination of a set of series helps identify changes with higher probability or more rapidly than when series are examined on a case‐by‐case basis. Some asymptotic theory is developed for maximum and average CUSUM detection tests. Monte Carlo experiments suggest that these both provide an improvement in detection relative to a univariate detector over a wide range of experimental parameters, given a sufficiently large number of co‐breaking series. This is robust to a cross‐sectional correlation in the errors (a factor structure) and heterogeneity in the break dates. We apply the test to a panel of UK price indices.

Optimal monetary policy using an unrestricted VAR

This paper proposes a simple benchmark for monetary policy. Assuming the true model of the economy is unknown, it is based on an unrestricted vector autoregression (VAR). The key result is that instead of deriving optimal policy using the original VAR equations as the constraint, when no restriction is placed on the correlation structure of the VAR disturbances, the constraint should be formed from a transformation of the VAR. This method is applied to the USA, 1964–2009. Significant welfare gains are found compared with actual policy and using a Taylor rule. Incorporating a zero interest rate lower bound lowers output and inflation. Copyright © 2010 John Wiley & Sons, Ltd.     

Relationship management for innovation: the central role of communication in australia's participation in two hi-tech industries

Individuals make decisions about whether innovations are adopted and transferred to new uses or locations. This Paper argues that relational competence Is critical for innovation management and technology transfer and that personal communication, formal and informal, is the core component in such competence. It shows how “close ties” and communication are critical to innovation, particularly given the changing nature and role of technolop management in the context o f rapidly increasing globalization. This is illustrated with reference to the communication in he mindset and practice of technology partnering in Australia's participation in the aerospace and telecommunications industries.     

Internationalization of private firms: environmental turbulence and organizational strategies and resources

Profiles of exporting and superior-performing private small and medium-sized enterprises (SMEs) are presented. Multivariate regression evidence suggests that SMEs focusing upon an offensive and market differentiation strategy of product/service protection is associated with the propensity and the intensity of exporting. Exporting SMEs are also associated with younger and manufacturing firms as well as firms with product or service quality and/or technology resources. The perceptions by SMEs of external environmental turbulence were not significantly associated with the exporting-dependent variables. Most notably, variables associated with exporting SMEs are not the same as those associated with superior firm performance. Moreover, exporting firms did not report superior levels of performance. Implications for policy-makers, practitioners and researchers are discussed.
