The generalization that island states are demographically more modern than continental states, and in particular that they have experienced greater fertility and mortality declines, is examined empirically for the Caribbean and the Pacific. A statistical analysis of recent Caribbean and Latin American data supports the view that island status is linked to an early demographic transition, independently of intervening, socio-economic factors, but the relationship is a modest one. The Pacific island data, however, tend to show the reverse, namely the persistence of high fertility despite favourable standards of living. One of the reasons for this contrast may be the greater importance of plantation agriculture and mass importation of labour in the Caribbean than in the Pacific. 相似文献
Medical tourism (also called medical travel, health tourism, or global health care) is a term initially coined by travel agencies and the mass media to describe the rapidly growing practice of travelling across international borders to obtain health care. In the past decade, the attempt to achieve better health while on holiday through relaxation, exercise, or visits to spas has been taken to a new level with the emergence of developing countries as destinations for medical tourism. It has grown dramatically in recent years primarily because of the high costs of treatment in rich countries, long waiting lists, the relative affordability of international air travel, favourable economic exchange rates, and the availability of well-qualified doctors and medical staff. Keeping in mind the rapid growth of this industry, a study was conducted to shed light on the importance of different factors that influence the travel motivations of US medical tourists to international destinations. 相似文献
Background: Chronic lymphocytic leukemia (CLL) is an orphan disease that primarily affects the elderly. The majority of symptomatic patients eligible for frontline treatment are unfit for fludarabine based chemoimmunotherapy. Historical treatment includes chlorambucil (Chl), bendamustine/rituximab (BR), and chlorambucil/rituximab/ChlR combination. Clinical guidelines now recommend the use of novel agents, such as ibrutinib (Ibr), in both frontline and relapse settings and other novel agents, such as idelalisib (with rituximab), in relapse settings. Despite compelling clinical results for novel agents, follow-up in clinical trials is relatively short and, thus, the comparative long-term benefits are still unknown.
Materials and methods: The authors developed a simulation model to generate treatment specific lifetime estimates of Overall Survival (OS) and Quality Adjusted Life Years (QALYs) for treatment with BR, Chl, ChlR, and Ibr. Two potential clinical scenarios were modelled: with and without novel agents for treating CLL. The model was based on health states relating to first- and second-line progression-free survival (PFS), post-progression survival, and death.
Results: Where novel agents were assumed unavailable, mean OS ranged from 5.4–8.5 years and QALYs from 3.5–6.1. Where novel agents were available, the mean OS increased to 10.0 years, with a corresponding increase in QALYs to 7.6. Frontline Ibr use followed by Physician’s Choice, including novel agents at relapse, resulted in projected increase in OS of between 18% (1.5 years) and 85% (4.6 years), corresponding to a 25–117% increase in QALYs, compared with currently available traditional therapies.
Limitations: The limitations of this analysis include immature OS data and the assumption of equivalent efficacy across all novel agents in terms of their impact on PFS and OS.
Conclusions: The use of novel agents is predicted to yield substantive gains in predicted lifetime OS and QALY improvements compared to traditional therapies in CLL patients who are ineligible for fludarabine-based chemoimmunotherapy. 相似文献
In the area of corporate finance, decisions regarding the constituents of overall capital structure are the most critical. These financing decisions are even more critical to lodging firms because of the unique nature of the industry. This study empirically investigates the effect of credit availability on the leverage of the lodging industry in the U.S. using multivariate analysis of variance. Three time points of differing credit availability (low, high, and average) were identified using the Case-Shiller home price index. Leverage, net leverage, and short-to-long-term debt ratios of large and small U.S. lodging firms were analyzed at these differing credit availability time points to assess any significant differences. Significant effects of credit availability were found on the leverage and net leverage of lodging firms, but no significant effect was found on the short- to long-term debt ratio of U.S. lodging firms. Interestingly, the leverage levels were found to be highest at the average availability of credit than when compared to the high and low availability of credit. 相似文献
ABSTRACTScholars and practitioners recognize that spreading word-of-mouth can play an important role in the formation of a hotel’s image. However, the relationships among various measures of online customer engagement are relatively unknown. The present study analyzes the relationships and quantifies the impacts of various measures of online engagement including the number of online reviews, overall rating, and relative ranking. The researchers used path analysis on a sample of 178 hotels to study the relationships among relevant variables and build a model to explain the impact of such measures (Figure 2). The results reveal there is a positive direct effect of the number of reviews on a hotel’s TripAdvisor rating. A negative direct effect was found between TripAdvisor rating and a hotel’s comparative ranking. Finally, the researchers discovered that TripAdvisor rating fully mediates the relationship between the number of reviews and a hotel’s comparative ranking. This article concludes with a discussion of both the theoretical and practical implications of such findings. 相似文献
This commentary explores some of the main issues raised in the recent Green Paper ‘Resolving Employment Rights Disputes–Option for Reform’. The Green Paper is the first comprehensive review of the industrial tribunals since their inception in 1964, and an assessment is made of various options for reform outlined in the Paper. 相似文献
