Global vector autoregressions (GVARs) have several attractive features: multiple potential channels for the international transmission of macroeconomic and financial shocks, a standardized economically appealing choice of variables for each country or region examined, systematic treatment of long-run properties through cointegration analysis, and flexible dynamic specification through vector error correction modeling. Pesaran et al. (2009) generate and evaluate forecasts from a paradigm GVAR with 26 countries, based on Dées, di Mauro et al. (2007). The current paper empirically assesses the GVAR in Dées, di Mauro et al. (2007) with impulse indicator saturation (IIS)??a new generic procedure for evaluating parameter constancy, which is a central element in model-based forecasting. The empirical results indicate substantial room for an improved, more robust specification of that GVAR. Some tests are suggestive of how to achieve such improvements. 相似文献

The test-score gap between black and white students should be seen as a crisis. We propose a testable model based on readily available data that will allow us to estimate the impact and interrelationships of a multitude of factors that may be partially responsible for the problem. The estimation of this model will require the joint efforts of experts in many areas of education as well as of experts in multilevel structural equation modeling. 相似文献

An event travel career is a potentially lifelong pattern of travel to events linked with an individual’s preferred leisure activity. This paper applies the concept of an event travel career to non-elite triathletes. For these active sport tourists, ongoing pursuit of an event travel career is arguably constrained by competing priorities that intervene between everyday life and their pursuit of an event travel career. In-depth interviews were conducted with 21 triathletes identified as pursuing an event travel career. Interpretive analysis revealed seven domains of competing priorities that could work to constrain their event travel career aspirations. These domains included familial relationships, domestic responsibilities, sociability, finances, leisure, wellbeing, and work/education. The seven competing priority domains were interrelated, and cyclical in their constraining effects. Data assisted in clarifying some defining characteristics of the event travel career concept, and challenged notions of leisure participation as entirely positive and fulfilling. 相似文献

Generalised linear regression models were used to identify factors associated with fatal/serious road traffic collision injuries for single- and multi-vehicle collisions. Single-vehicle collisions and multi-vehicle collisions occurring during the hours of darkness or on a wet road surface had reduced likelihood of a fatal/serious injury. Single-vehicle ‘driver with passengers’ collisions occurring at junctions or on a hill/gradient were less likely to result in a fatal/serious injury. Multi-vehicle rear-end/angle collisions had reduced likelihood of a fatal/serious injury. Single-vehicle ‘driver only’ collisions and multi-vehicle collisions occurring on a public/bank holiday or on a hill/gradient were more likely to result in a fatal/serious injury. Single-vehicle collisions involving male drivers had increased likelihood of a fatal/serious injury and single-vehicle ‘driver with passengers’ collisions involving drivers under the age of 25 years also had increased likelihood of a fatal/serious injury. Findings can enlighten decision-makers to circumstances leading to fatal/serious injuries. 相似文献

The U.S. Bureau of Labor Statistics (BLS) provides essential, trustworthy, highly visible statistics that promote economic efficiency. However, its ability to do so is threatened by many challenges, chief among which is its funding situation. This article updates important stakeholders, such as those at NABE, on the situation at BLS. The paper reviews evidence on the vital role played by BLS products, how BLS maintains high data integrity, and evidence of users’ trust in the data. This is followed by discussion of the agency’s continuous efforts to improve efficiency. Despite the agency’s importance and efficiency, its funding has been flat in nominal terms since 2009, leading to a $90 million shortfall (15% below that needed) in real terms by FY2018. The BLS has needed to curtail spending in ways that are not sustainable, slowing modernization and raising the risk of data errors or delayed releases. With adequate funding, BLS could greatly speed modernization and better serve its customers in many ways. The paper concludes with a call to action: steps that NABE economists and other data users should take to help assure that BLS continues to provide the data that we all need in order to preserve our national vitality. 相似文献

This conceptual paper contributes to tourism knowledge by proposing a spirituality-based platform in tourism higher education. Through this platform, the authors show how tourism education that supports discussion on spiritual development can help to create global citizens who are able to understand their potential as social, cultural and environmental stewards. This paper reviews recent developments shaping tourism education and examines the contemporary tourism educational landscape that supports a spirituality-based educational approach. The 7th platform of tourism studies is offered through a spirituality-based approach to knowledge and examples are given of how we can develop such a platform in tourism higher education. 相似文献

Not-for-profit organisations often consider marketing to be inappropriate to their needs. This may well be true if marketing is thought of in its traditional and outdated ‘transactionally’ focused mode. Relationship marketing, with a focus on relationships rather than transactions, and multiple markets, has the ability to meet the unique needs of not-for-profit organisations.

The nature and extent of service user involvement in critical care research and quality improvement: A scoping review of the literature 下载免费PDF全文
Suzanne Bench Erica Eassom Konstantina Poursanidou 《International Journal of Consumer Studies》2018,42(2):217-231
The importance of involving patients and the public in health care research is globally recognized, but how best to do this in critical care is unclear. The aim of this first published review was to explore the extent and nature of evidence on service user involvement in critical care research and quality improvement. Using the scoping review framework described by Arksey and O'Malley ( 2005 ), a team of service user and critical care researchers searched eleven online databases, reviewed relevant web sites, conducted forward and backward citation searching and contacted subject experts. Extracted data were subjected to a narrative synthesis based on the objectives of the review. Findings from a broad range of evidence support that involvement is becoming more commonplace and that experiences are generally positive. Data extracted from 34 publications identify that involvement is most commonly reported at the level of consultation or participation in project teams, however, the extent to which involvement impacts on projects output remains unclear. Key barriers and facilitators relate to the challenge of recruiting a diverse group of service users, dealing with power hierarchies, being adaptable and effective consideration of the resource requirements. More research is required to identify the most effective methods to support the opportunity for involvement and more thorough reporting of service user involvement practices is strongly recommended. 相似文献
