In the current climate of intense turbulence, tourism must transform to a more sustainable development platform. Yet it remains unclear how the concept of sustainability is embedded at different levels of government policy and planning, and how this has evolved over time. This paper identifies the concept of sustainability as it is articulated in 339 Australian tourism strategic planning and policy documents published between 2000 and 2011. The paper examines the extent to which the concept of sustainable tourism is evident in the discourse of Australian tourism strategic planning documents at the national, state, regional and local levels, as well as the balance of the discourse in relation to sustainability objectives. The results show that the frequency of occurrence of sustainability as a concept has slightly increased in strategies over the past decade. At the same time, there has been a shift in the conceptualisation of sustainability, with thinking evolving from nature-based, social and triple bottom line concepts toward a focus on climate change, responsibility, adaption and transformation. 相似文献

Risky arbitraging based on interest rate differentials between two countries is typically referred to as a carry trade. Up until the recent global financial crisis, these trades generated years of persistent positive returns, which were hard to reconcile with standard pricing kernels. In 2008 these trades blew up, which seemed to weaken the case for a puzzle relating to predictable currency returns. But the rise and fall of this puzzle in the academic literature has only been concerned with naïve carry trades based on yield signals alone. We show, however, that some simple and more realistic fundamentals-augmented trading strategies would have generated strong and sustained positive profits that endured through the turmoil. 相似文献

Despite the claims made about the effectiveness of cross‐cultural training programs, few studies have examined the reliability and validity of the instruments used in these training programs. In this study, the authors examined the factor structure of the Cross‐Cultural Adaptability Inventory (CCAI) via a confirmatory factor analytic approach. A series of confirmatory factor analytic models was tested and applied at the item level to both the CCAI and Goldberg's Big Five Inventory. A confirmatory factor analysis (CFA) model in which a method factor was estimated fits the data significantly better than a model without such a method effect. Further, the method factor suppressed substantive relationships such that the two CCAI factors of Emotional Resilience and Personal Autonomy became significant correlates with self‐reported number of international job assignments after accounting for method variance. Implications for research and practice are discussed. 相似文献

Within the competitive foodservice industry, the ability to accurately measure the meal process known as turn-time is critical to the success of the firms in the industry. This is traditionally done through linear techniques such as multiple least squares (aka linear regression) or analysis of variance (ANOVA). However, linear techniques have theoretical properties that can potentially lead to bias in measurements of time duration variables, while survival models were designed for that purpose. This study utilized simulated data of a dine-in restaurant to test and compare the ability of linear regression to five survival models (proportional hazard models) for predicting the duration of turn-time. The results from the simulated trials show that while some of the survival models held incremental improvements, linear regression performed adequately for predicting the duration of turn-time even when taking the biased predictions into account. For operators who are in their infancy of developing restaurant revenue management systems, linear regression is recommended due to the practical ease of the models. On the other hand, operators who have well-established restaurant revenue management systems interested in incremental improvements should opt for survival models in predicting turn-time. 相似文献

The paper presents the results of an empirical study that aims to investigate the impact of interfirm co-operation over innovation on four different types of innovation: product, process, incremental and radical innovation. Drawing on the innovative milieu literature, the impact on the above four types of innovation was tested for both external and internal factors of innovation such as inter-firm co-operation over innovation, production networking, as well as R&D investment and R&D personnel. Four probit models were run by using a unique data set compiled as part of the Regional Innovation Strategy for the West Midlands (UK) Project. The main findings of the paper seem to provide substantial evidence that, for any of the four types of innovation considered, firms' capacity to innovate could greatly improve if they co-operated with other firms over innovation in addition to or instead of investing in R&D. Innovation policy should not overlook, therefore, the systemic component of innovation and ought to attempt to initiate and support inter-firm co-operation. This would mean a renewed and more focused analysis of firms' clusters as part of a multi-faceted approach to innovation policy. 相似文献

In this paper, we analyse the impact of persistent cycles on the well‐known semi‐parametric unit root tests of Phillips and Perron (1988, Biometrika, Vol. 75, pp. 335–346). It is shown, both analytically and through Monte Carlo simulations, that the presence of complex (near) unit roots can severely bias the size properties of these tests. Given the popularity of these tests with applied researchers and their routine presence in most econometric software packages, the results presented in this paper suggest that practitioners should treat the outcomes of these tests with some caution when applied to data which display a strong cyclical component. 相似文献

During the 1980s and until the mid‐1990s, Peru experienced one of the bloodiest conflicts in contemporary Latin America, initiated by the armed insurrection launched by the Partido Comunista del Perú – Sendero Luminoso (Shining Path). Most guerrilla activity, armed confrontations and civilian fatalities occurred in Andean rural districts. The intensity of violence declined following the detention of PCP‐SL General Secretary Abimael Guzmán and other leading cadres in 1992–3, which resulted in the dismantling of a substantial component of the organization's military apparatus and support networks. This paper examines how surviving PCP‐SL militants attempted to regroup and respond strategically and tactically to such a devastating setback, focusing on its dealings with the civilian population, particularly coca‐producing smallholders. Counter‐insurgency measures pursued by the Peruvian state are also analysed. The paper concludes with an assessment of the current disposition of guerrilla – rural population – state relations in the main areas of conflict. 相似文献

How have COVID-19-related restrictions affected consumption levels and life satisfaction in low-income countries? We conducted phone surveys with 577 households in Liberia to compare consumption patterns across three points in time: November 2019 (pre-COVID-19), May 2020 (short term), and September 2020 (medium term). This article analyzes the impacts of the Covid-19 pandemic and the related restrictions on food and nonfood consumption, which we categorize as “material” welfare and life satisfaction, which we categorize as “nonmaterial” welfare. We find differences between food and nonfood consumption patterns under pandemic conditions. In particular, consumption by households dependent on food and labor markets was negatively affected by the pandemic. In terms of life satisfaction, we find that most respondents perceived their lives to have worsened due to the pandemic. 相似文献
