气候变化和林业:REDD入门

在如何应对气候变化的讨论中,最有争议的问题之一是REDD(减少毁坏和林地退化造成的碳排放)。在基于市场减排战略中的作用,分析审查REDD活动的成本表明,REDD不但在减少GHG排放的全球战略中发挥重要作用,还可以保护热带雨林提供生物多样性和重要生态系统服务。但是REDD项目限于在一定地域,除非全球森林都被纳入REDD,否则漏洞无法消除,此外,REDD在政策设计问题上存在一定争议,因此还需进一步的研究讨论。     

Terrorism and women’s employment in Afghanistan

ABSTRACT

Afghanistan is one of the most dangerous countries for women and has the sixth lowest women’s employment rate globally. Evidence shows that security concerns prevent women from working, but there is little work estimating the magnitude of or mechanism behind these effects. We address this gap in the literature by estimating the relationship between increased terrorist attacks and women’s employment using the Global Terrorism Database (GTD) and the 2015 Demographic and Health Survey (DHS). We find the number of attacks is negatively associated with men’s and women’s employment, yet the relative magnitude is larger for women due to their low employment rate. Conversely, we find that an increase in fatalities is associated with higher women’s employment, suggesting that women replace men that have died from attacks. This research illuminates a potential link between women’s employment and terrorism, thus adding to the ever-increasing knowledge of the costs of conflict.     

Deaths of older Australians related to their use of motorised mobility scooters

This study describes motorized mobility scooter (MMS) rider-related fatalities in the older Australian population during the years 2000–2011, identified from the National Coronial Information System. Seventy-seven fatalities were identified, most aged 80 years or older (74.1%) and males predominated (76.6%). Most deaths (88.3%) resulted from collisions with motor vehicles or falling from the MMS. These findings are consistent with the reported morbidity data. Challenges to MMS case identification included lack of specification in reports to Coroners and inadequate codes. Improved specificity and coding are necessary to fully describe the extent of MMS-related injury. This study raises the issue of emerging largely unregulated consumer products. Further research is required to understand the uptake and use of MMS in the ageing population. Strategies are needed to decrease rider injuries whilst meeting community mobility needs.     

Intergovernmental Fiscal Arrangements and Provincial Consumption Risk Sharing in China

This paper utilizes a panel data set on two major fiscal reforms in China—the fiscal contract system (FCS) in 1980-93 and the tax-sharing system (TSS) after 1994—to examine how the various aspects of intergovernmental fiscal arrangement affect the ability of the fiscal system to facilitate risk sharing. The high revenue decentralization and the proliferation of extrabudgetary revenue items in the FCS generally weakened the central government's ability to support interprovincial risk sharing. This situation was reversed in the TSS period. In addition, the effect of central-to-local transfer (transfer-in) and local-to-central transfer (transfer-out) on risk sharing was asymmetric in the sense that transfer-out enhances risk sharing but transfer-in does not.     

How Exhausting!? Emotion Crossover in Organizational Social Networks

Does emotional exhaustion cross over between employees? Departing from the traditional within-person view, we draw on the crossover model to argue and test an interpersonal model of emotional exhaustion. We conducted a sociocentric social network study in a U.S. construction company and found that employees had similar levels of emotional exhaustion to co-workers with whom they had interaction and advice ties and structurally equivalent network positions, but that they did not have similar emotional exhaustion to friends or supervisors. We advance scholarly understanding of emotion crossover by theorizing and simultaneously testing important organizationally structured patterns of interaction and transfer previously unexamined, examined only in isolation or examined in a piecemeal manner. Our results highlight the importance of exploring the influence of structural and relational patterns embedded in the organization’s formal and informal structures and provide a theoretical and methodological platform to advance our understanding of crossover, emotional contagion and important outcomes at work.     

Should Cruise Ports Market Ecotourism? A Comparative Analysis of Passenger Spending Expectations within the Panama Canal Watershed

This study examined the expected spending patterns of cruise ship passengers as they debarked ships at ports within the Panama Canal Watershed. Results suggest that targeting marketing efforts toward ecotourism opportunities may increase long‐term ecological and economic benefits to port communities and local businesses. Most respondents were interested in ecotourism‐related activities in the Panama Canal Zone and nearby coastal areas. Furthermore, the ecotourism‐related market segments expected to spend significantly more money in port than conventional tourists. The growing ecotourism market represents an important opportunity for the cruise industry to partner with local ecotourism operators, enhancing profitability while simultaneously supporting sustainable development.

Mortgage lending in Chicago and Los Angeles: A paired testing study of the pre-application process

In 2000, the Urban Institute paired African-American and Hispanic testers with whites and sent the pairs to visit lenders in Chicago and Los Angeles, in order to inquire about information on obtaining a home mortgage. In Chicago, African Americans and Hispanics systematically received less information and assistance than comparable whites; while in Los Angeles, the treatment of minority and white testers did not differ statistically from each other. Multivariate analyses for Chicago indicate that large lenders treat minorities more favorably than smaller lenders and that lenders with substantial numbers of applications from African-Americans treat African-Americans more favorably than lenders with predominantly white application pools.     

Auditor quality,audit fees,organizational structure,and risk taking in the US life insurance industry

Using a system of simultaneous equations, this study examines the relation among external audit monitoring, in the US life insurance industry. We find insurers with higher leverage risk and surplus risk are more likely to use Big‐4 auditors and to pay higher fees. In return, insurers hiring Big‐4 auditors and paying higher audit fees have lower leverage risk and surplus risk. Second, the results suggest that mutual life insurers have a higher leverage risk and surplus risk than stock life insurers. This evidence is in contrast to that for property–liability insurance companies. Third, we find insurers are less likely to hire Big‐4 auditors and to pay higher audit fees after implementation of the Sarbanes–Oxley Act (SOX). Finally, life insurers with Big‐4 auditors or paying higher audit fees are more likely to take lower risks after the implementation of SOX.
