EROSION ON LOGGING ROADS IN REDWOOD CREEK,NORTHWESTERN CALIFORNIA1

Road-related erosion was estimated by measuring 100 randomly located plots on a 180 km road network in the middle reach of R'dwood Creek in northwestern California. The estimated erosion ratn of 177 m³ km^-1 was contrasted with two earlier studies in nearby parts of the same watershed. A sizable proportion of the great reduction in erosion from that reported in the earlier studies is attributed to changes in forest practice rules. Those changes have resulted in better placement and sizing of culverts and, especially, to less reliance on culverts to handle runoff from logging roads.     

Explaining support for renewable energy: commitments to self-sufficiency and communion

ABSTRACT

Across the political spectrum, people favour renewable energy. For political liberals, this support has been attributed to concern for the environment; in contrast, the bases of conservatives’ support are less clear. Derived from interviews with a diverse sample of households in Washington State, USA, and a vignette experiment with a representative sample of American households, results show that Democrats (liberals) and Republicans (conservatives) have different moral intuitions, with Democrats emphasizing communion and both Democrats and Republicans valuing self-sufficiency. These findings explain how politically polarized environmental attitudes can exist alongside a shared support for renewable energy. The study therefore contributes to the literature on environmental concern and behaviour, and has implications for policies aimed at increasing adoption of renewable energy as well as pro-environmental behaviour more broadly.     

新《环境保护法》对重污染企业盈余管理的影响研究——基于政治成本假说的实证检验

本文利用新《环境保护法》实施这一外生事件,采用双重差分模型,从应计盈余管理和真实盈余管理两个方面实证检验了政治成本对重污染企业盈余管理的影响。研究发现在新《环境保护法》实施后,相比于非污染企业,重污染企业面临更高的政治成本,其进行了显著的向上应计盈余管理和真实盈余管理,向外界传递了企业未来发展良好的信息。上述研究结论经过一系列稳健性检验依然成立。进一步的异质性检验表明:①基于产权性质的分析表明,本文的研究结论在非国有企业的子样本组中更为明显;②基于企业规模的分析表明,小规模重污染企业更倾向于进行向上应计盈余管理,但不同规模重污染企业的真实盈余管理没有显著差异;③基于市场竞争程度的分析表明,高市场竞争环境下的重污染企业更倾向于采取向上应计盈余管理,低市场竞争环境下的重污染企业更倾向于进行向上真实盈余管理;④基于经济发展水平的分析表明,东部地区的重污染企业倾向于向上应计盈余管理和真实盈余管理。本文研究结论与西方的“政治成本假说”并不相符,为中国情境下的“政治成本理论”发展提供了另一种证据,同时为进一步加强新《环境保护法》的环境规制效果提供了决策参考。     

The role of supervisor political skill in mentoring: Dual motivational perspectives

Drawing on self‐determination and self‐concept‐based theories, this study investigated the mediating effects of psychological empowerment and organization‐based self‐esteem on the relationship between supervisory mentoring and employee performance and the moderating effect of supervisor political skill on the direct and first stage of the indirect effects. Data were obtained from a sample of 330 subordinate–supervisor dyads from the People's Republic of China. Using PROCESS of conditional indirect effect, we found support for the moderated direct and indirect effects of supervisory mentoring. First, supervisor political skill moderates the direct effect of supervisory mentoring on employee promotability. Second, supervisor political skill moderates the indirect effect of supervisory mentoring on the following: (i) employee promotability via both psychological empowerment and organization‐based self‐esteem and (ii) contextual performance only via psychological empowerment. These direct and indirect effects of supervisory mentoring are stronger when supervisors demonstrate a higher level of political skill. Copyright © 2013 John Wiley & Sons, Ltd.     

Towards a politics of disaster response: presidential disaster instructions in China, 1998–2012

China's disaster management system contains no law‐based presidential disaster declarations; however, the national leader's instructions (pishi in Chinese) play a similar role to disaster declarations, which increase the intensity of disaster relief. This raises the question of what affects presidential disaster instructions within an authoritarian regime. This research shows that China's disaster politics depend on a crisis threshold system for operation and that the public and social features of disasters are at the core of this system. China's political cycle has no significant impact on disaster politics. A change in the emergency management system has a significant bearing on presidential disaster instructions, reflecting the strong influence of the concept of rule of law and benefiting the sustainable development of the emergency management system. In terms of disaster politics research, unlocking the black box of China's disaster politics and increasing the number of comparative political studies will benefit the development of empirical and theoretical study.     

The interactive effects of conscientiousness,openness to experience,and political skill on job performance in complex jobs: The importance of context

Caveats concerning the ability of personality to predict job performance have been raised because of seemingly modest criterion‐related validity. The goal of the present research was to test whether narrowing the context via the type of job (i.e., jobs with complex task demands) and adding a social skill‐related moderator (i.e., political skill) would improve performance prediction. Further, along with political skill, the broad factor of personality demonstrated in prior research to have the strongest criterion validity (i.e., conscientiousness) was joined with a narrow construct closely related to openness to experience (i.e., learning approach) in a three‐way interactive prediction of supervisor‐rated task performance. With the employee–supervisor dyads among professionals, but not with the control group of non‐professional employees, task performance was predicted by the three‐way interaction, such that those high on all three received the highest performance ratings. Implications, strengths and limitations, and directions for future research are discussed. Copyright © 2012 John Wiley & Sons, Ltd.     

自然资源的库兹涅茨曲线:来自中国省级面板数据的证据

本文运用1978-2011年我国30个省份的面板数据,对我国省级层面资源丰裕度与经济增长的关系进行了检验.研究发现,我国省级层面资源丰裕度与经济增长之间的关系并不是单一线性的,而是一种非线性的动态演变关系.当使用其他资源丰裕度和经济增长的指标进行稳健性检验,这种强烈的非线性关系仍然存在.更进一步,对自然资源作用经济增长的机制进行实证检验,结果显示:长期中丰裕的自然资源会通过降低人力资本和物质资本的投资对经济结构产生“诅咒”;恶化政府与市场的关系、阻碍非国有经济的发展、中介组织的发育和法律的完善等,从而对政治制度产生“诅咒”.     

Does size matter? Comparing the party politics of climate change in Australia and Norway

ABSTRACT

The implications of state size for the party politics of climate change are examined, and in particular its effect in facilitating or impeding cross-party consensus on the issue. This issue is explored through an in-depth, qualitative comparison of Australia and Norway, which are shown to be comparable in important respects yet differ in terms of their size and climate politics. Original primary data is presented from 44 interviews with policymakers and policy-shapers in both countries, which shows that, to the limited extent that state size moderates the parties’ behaviour, it is the countries’ geographical – not economic – size that matters. Institutional factors are found to play a more significant role, however, and the corporatist features of state-business cooperation, strong ENGOs and compensatory welfare arrangements are highlighted as particularly important.
