三农问题是我国全面建设小康社会最根本、最重要的问题.要实现农业增效、农民增收、农村繁荣的目标,必须切实加大对三农的信贷投入.目前我国城乡金融资源严重失衡、农村信用环境不佳、农业保险发展滞后,导致三农发展的资金“瓶颈”依然突出.为此,地方政府应加强顶层设计,着力优化地方金融机构布局,并出台相应的扶持政策,帮助涉农金融机构克服各种障碍,切实增加对三农的信贷供给.  相似文献

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.  相似文献

ABSTRACT

The purpose of this article is to examine representations of women's leisure portrayed on the popular Netflix television series Orange Is the New Black (OITNB). Using a feminist lens rooted in the notion of interconnectivity, we draw on four television tropes proposed by Pozner (2010 Pozner, J. L. (2010). Reality bites back: The troubling truth about guilty pleasure TV. Berkeley, CA: Seal Press. [Google Scholar]) that are commonly used to depict women characters on television to analyze representations of women's leisure in the first three seasons of OITNB. Our analysis reveals the complex and messy ways representations of women's leisure on OITNB can be used to discipline, reproduce, but also challenge power relations associated with common media tropes, acting as a form of political practice. We conclude by considering the implications of how these representations can influence the lives of women consuming this media content as part of their leisure.  相似文献

We develop a structural risk‐neutral model for energy market modifying along several directions the approach introduced in Aïd et al. In particular, a scarcity function is introduced to allow important deviations of the spot price from the marginal fuel price, producing price spikes. We focus on pricing and hedging electricity derivatives. The hedging instruments are forward contracts on fuels and electricity. The presence of production capacities and electricity demand makes such a market incomplete. We follow a local risk minimization approach to price and hedge energy derivatives. Despite the richness of information included in the spot model, we obtain closed‐form formulae for futures prices and semiexplicit formulae for spread options and European options on electricity forward contracts. An analysis of the electricity price risk premium is provided showing the contribution of demand and capacity to the futures prices. We show that when far from delivery, electricity futures behave like a basket of futures on fuels.  相似文献

The Great East Japan Earthquake and the successive accidents at the Fukushima Daiichi Nuclear Power Station are stark reminders of the importance of energy, which is the basis of economic activity and national governance. Urgent responses have been conducted since March 11, 2011, including controlling the consequences of the nuclear accident, dealing with the short‐term power shortages, and a comprehensive review of Japan's long‐term national energy policy. Nationwide discussions and reviews of these issues are still continuing. Even today, more than 2 years after March 11, many problems remain unsolved and Japanese society has to face uncertainty and challenges about its energy future. In the current difficult situation, Japan needs to achieve “3Es (e nergy security, environmental protection, and economic efficiency)” plus “S” (safety) and “M” (macro economy protection) simultaneously, taking account of the new realities following the Fukushima accident. This paper tries to identify the energy‐related challenges that Japan has to face and tries to recommend the concept of the “energy best mix policy” for Japan, by describing the present status of energy issues in Japan and the national debate on energy policy.  相似文献

ABSTRACT

The current paper offers a new conceptual model to understanding innovation processes in professional service firms, to make hidden relationships more explicit and to find out what are the issues still unexplored. The paper employs a systematic literature review, and draws upon original categorizations of extant literature, to identify main processes for each category of PSFs. It unveils connections among a wide range of factors setting a conceptual model for innovation pathways and highlighting neglected questions relevant from both the theoretical and the practical perspectives.  相似文献

ABSTRACT

This article examines the effect of technological diversity, knowledge flow and capacity on industrial innovation performance. We suggest that there is an inverse U-shaped relationship between technological diversity and industrial innovation performance. Moreover, knowledge flow and knowledge capacity are hypothesised as negatively moderating the effect of technological diversity on industrial innovation performance. We use negative binomial regression to test the hypotheses in a panel data of 360 industry-year cases and the findings support our prediction. Managerial implications and future research directions are discussed.  相似文献

The focus of this paper is on Lithuania, whose government released an ambitious innovation strategy to become an innovative services hub for Northern Europe by 2015, and an innovation hub by 2020. Biotechnology has been identified as a strategic sector, and whether Lithuania will be able to achieve its ambition of a fully functioning biotechnology sectoral system of innovation will be explored. With the Lithuanian government declaring that they will intervene to achieve their innovation goals, this paper argues that sound policy intervention is possible and can be done in a way that avoids the limitations of past systemic approaches. The policy approach presented is based on a modified extended industry life cycle, and the movement of system structures through three phases – background, pre-emergence and emergence – and explains how each phase lays the groundwork for transition to the next phase.  相似文献

We analyze a monopolist's incentive to innovate a new antibiotic which is connected to the same pool of antibiotic treatment efficacy as is another drug produced by a generic industry. We outline the differences of antibiotic use under market conditions and in the social optimum. A time- and state-dependent tax-subsidy mechanism is proposed to induce the monopolist and generic industry to exploit antibiotic efficacy optimally.  相似文献

This paper examines the validity of purchasing power parity hypothesis for 33 African countries using recently developed Fourier unit root tests by Christopoulos and León‐Ledesma that account for the existence of multiple breaks in the real exchange rates. The results support the evidence of the PPP in 20 countries, showing that most of the real exchange rates in the selected countries are characterised by linear or nonlinear stationary around multiple temporary mean changes.  相似文献
