A rapid assessment of wildlife tourism risk posed to cetaceans in Asia

Dolphin-watching tourism is growing globally. In developing countries, the typically low environmental awareness of operators and poorly enforced or non-existent regulations exacerbate risks to wildlife. Ecological indicators like behavioural responses are useful to assess wildlife tourism, but obtaining such data is slow and expensive. We modified the Driver–Pressure–State–Impact–Response (DPSIR) framework to rapidly assess the risk of dolphin-watching tourism harming, displacing or causing local extinction to dolphin populations, using human dimension data to complement limited ecological data. We assessed industries at seven dolphin-watching sites in six countries in Asia: Cambodia, India, Indonesia, Malaysia, Thailand, and the Philippines. All sites have reached or almost reached financial saturation except Cambodia and Malaysia. We find high risk to dolphins at the sites in India and Indonesia and intermediate risk at the site in Cambodia. Pending more ecological data, the risk at Thailand, the Philippines, and Malaysian sites might be low. Our analysis also indicates site-specific conservation recommendations for Driver, Pressure and Response. We suggest that the DPSIR framework is useful to assess the risk of a wildlife watching industry, even when the impact is uncertain due to insufficient ecological data.     

Two‐State Option Pricing: Binomial Models Revisited

This article revisits the topic of two‐state option pricing. It examines the models developed by Cox, Ross, and Rubinstein (1979), Rendleman and Bartter (1979), and Trigeorgis (1991) and presents two alternative binomial models based on the continuous‐time and discrete‐time geometric Brownian motion processes, respectively. This work generalizes the standard binomial approach, incorporating the main existing models as particular cases. The proposed models are straightforward and flexible, accommodate any drift condition, and afford additional insights into binomial trees and lattice models in general. Furthermore, the alternative parameterizations are free of the negative aspects associated with the Cox, Ross, and Rubinstein model. © 2001 John Wiley & Sons, Inc.

Democracy across Gender Diversity and Ethnicity of Middle Eastern SMEs: How Does Performance Differ?

This paper examines the relationship between boards of directors' demographic diversity and firms' financial performance. In particular, we highlight how women and ethnic minorities can affect Middle Eastern SMEs' financial performance. Using an unbalanced panel of 1,855 firm‐year observations of 371 boards of directors from nine Middle Eastern countries, our results support the positive impact of women and ethnic minority group members on Middle Eastern firms' performance. However, our evidence implies that when Western ethnic minority members increase, firms' performances tend to decrease, because these board members are appointed for regional and international board reputation legitimacy, personal business agendas, and links to the external corporate environment.     

Green human resource management and the enablers of green organisational culture: Enhancing a firm's environmental performance for sustainable development

Scholars have shown that green human resource management (GHRM) practices enhance a firm's environmental performance. However, existing studies fail to explain how GHRM initiatives can enable a green organisational culture or how such a culture affects the environmental performance and sustainable development of the firm. This paper examines the relationship between GHRM practices, the enablers of green organisational culture, and a firm's environmental performance. We conduct a large‐scale survey of 204 employees at Chinese manufacturing firms. Our findings suggest that proenvironmental HRM practices including hiring, training, appraisal, and incentivisation support the development of the enablers of green organisational culture. We suggest the key enablers of green organisational culture include leadership emphasis, message credibility, peer involvement, and employee empowerment. Our paper contributes to HRM theory in terms of originality and utility of research by explaining that the enablers of green organisational culture positively mediate the relationship between GHRM practices and environmental performance. Managers are provided with a detailed understanding of the GHRM practices needed to enable an organisational culture of environmentally aware employees. Finally, we address potential implications of this work for teaching green organisational culture to future generations of responsible managers.     

Firm productivity and importing: Evidence from Chinese manufacturing firms

This paper investigates various aspects of the relationship between firm productivity and importing for a large sample of Chinese firms between 2002 and 2006 making a distinction between the origin, variety, skill and technology content of imports. Employing a random effects probit model and a propensity score matching with difference‐in‐differences (PSM–DID) approach and treating imports as endogenous in our measure of total factor productivity (TFP) (De Loecker 2007), we test the self‐selection and learning‐by‐doing hypotheses. Our results show evidence of a bi‐directional causal relationship between importing and productivity. Although importing firms tend to be more productive before entering the import market, once they start importing firms experience significant productivity gains for up to two years following entry. We also find evidence of learning effects following the decision to import, which is stronger when import starters source their products from high‐income economies, import a wider variety of products and import products with a higher skill and technology content. A number of robustness checks confirm the learning effects of importing on TFP growth.     

Economic modeling to evaluate the impact of chronic myeloid leukemia therapy management on the oncology care model in the US

Abstract

Objective: To develop an economic model to evaluate changes in healthcare costs driven by restricting usage of branded tyrosine kinase inhibitors (TKIs) through substitution with generic imatinib among chronic myeloid leukemia (CML) patients in a typical Oncology Care Model (OCM) practice, and examine the impact on Performance-Based Payment (PBP) eligibility.

Methods: An Excel-based economic model of an OCM practice with 1,000 cancer patients during a 6-month episode of care was developed. Cancer types and proportions of patients treated in the practice were estimated from an OCM report. All-cause healthcare costs were obtained from published literature. It was assumed that if a practice restricts usage of branded TKIs for newly-diagnosed CML patients, 80% of the market share of branded imatinib and 50% of the market shares of 2^nd-gen TKIs would shift to generic imatinib. Among established TKI-treated patients, it was assumed that 80% of the market share of branded imatinib and no patients treated with 2^nd-gen TKIs would shift to the generic.

Results: Four CML patients were estimated for a 1,000-cancer patient OCM practice with a total baseline healthcare cost of $51,345,812 during a 6-month episode. If the practice restricts usage of branded TKIs, the shift from 2^nd-gen TKIs to generic imatinib would reduce costs by $12,970, while shifting from branded to generic imatinib lowers costs by $25,250 during a 6-month episode. Minimum reductions of $3,013,832 in a one-sided risk model and $2,372,010 in a two-sided risk model are required for PBP eligibility; the shift from 2^nd-gen TKIs to generic imatinib would account for 0.4% and 0.5% of the savings required for a PBP, respectively.

Conclusions: This analysis indicates that the potential cost reduction associated with restricting branded TKI usage among CML patients in an OCM setting will represent only a small proportion of the cost reduction needed for PBP eligibility.     

Sex as Leisure in Later life: A Netnographic Approach

ABSTRACT

This study aimed to provide an in-depth understanding of the roles of sex as leisure activity in later life and to explore the links between sex and wellbeing at this life stage. Applying a netnographic approach, the study followed a full year of activity in 14 leading English language-based seniors’ online communities. The final dataset of 2,534 sex-related posts was analyzed using constructivist grounded theory. The findings reflect the multiple roles of sex in older adulthood, highlighting its importance, leisurely qualities, and benefits. The community members also discussed various constraints limiting sexual function and expression. Many posters, however, did not treat these constraints as a verdict and reported adopting myriad strategies to maintain sexuality despite limiting constraints. These findings suggest that sexual activities encompass all patterns of leisure in older adulthood and highlight the threats of leisure constraints to wellbeing and the importance of constraint negotiation.     

Multinational Enterprises and Foreign Direct Investment: Introduction

This study uses firm‐level data on a large sample of European manufacturing firms to investigate the links between opening up foreign affiliates and firms’ productivity. The analysis is guided by recent theoretical models of international trade with firm heterogeneity. The paper finds that while only a small share of euro area firms locate affiliates abroad, these firms account for over‐proportionally large shares of output, employment and profits in their home countries. They have higher survival rates and their productivity growth is also higher. The strongest contribution is by productivity growth of existing firms with a multinational status rather than entry into the multinational status. finally, there are performance premia for multinationals with a large number of affiliates abroad relative to those with a small number.
