海南中部山区森林生态系统服务功能价值评估

海南中部山区是全省生态功能的核心区,对维持全岛生态平衡与可持续发展起着十分重要的作用。本文依据2005年SPOT2、SPOT4遥感影像（10米分辨率）所提取的专题图层分析统计出中部山区森林生态系统类型和面积,提出了各类型生态系统服务功能评价指标沐系,分为提供产品、调节功能、文化功能和支持功能4种类型;并利用生态经济相关理论基础对备服务功能价值进行了初步评价．结果表明,海南中部山区森林生态系统8种类型9种服务功能总价值为1549．5×10^8元／a,其中调节功能达1472．8×10^8元,占总服务功能价值的90％以上。为进一步提高人们的生态环保意识和促进海南生态补偿机制的建立提供重要参考。     

SEO领导风格对绩效影响的研究——基于创业导向视角的实证分析

近些年,采用创新方法解决社会问题的社会创业组织(SEO)不断在全球兴起,并引起国内外社会科学有关学者们的关注和研究兴趣.其中,社会创业组织领导风格对SEO价值创造过程以及绩效的影响问题成为重要的研究课题之一.目前,国外在这一方面的研究取得初步成效.但是,在中国,该方面的实际研究处于空白.本文研究试图对此做一些弥补:一方面以Covin和Slevin(1991)开发的量表为基础,再借鉴H.Morris(2011)对创新性、超前行动和风险承担在社会创业情境下的界定,对创业导向的测量题项进行了修订,以反映社会创业与传统创业相区别的特征;另一方面,选取中国开展社会创业一年以上的个体或非营利组织为研究对象与样本开展中国本土化的实证研究.本研究发现,变革型领导对创新、风险承担和超前行动三个变量具有积极影响,以及创新和超前行动与社会创业组织绩效具有正向关系.     

Merit and Evaluation Models for Managers in the National Health System： An Empirical Study

The national health system （NHS） complexity increase requires a review of the managerial human resources evaluation and recruiting methods, considering that nowadays doctors need to improve not just their clinical capabilities, but also managerial competences. At this end it is important to develop performances control models and to identify appropriate results indicators, with the aim of introducing an effective doctors selection system for managerial roles. The paper considers the Italian situation and tests the current evaluation and selection methods, by analysing the literature and the existing legislation and by interviewing experts. Moreover, in order to reach an innovative model, complex organizations have been taken into account as benchmarks. Three different categories of experts have been interviewed and texted： national health care organizations managers, companies managers, and business consultants. The 137 interviewed experts have been asked about four main questions concerning the evaluation for hiring managers as chief medical director, department director, and head of complex units. The conducted research suggests four different options in order to evaluate and to select heads of complex unit for the most strategic roles. By consequence, the analysis shows that required characteristics must be managerial attitudes as well as clinical capabilities.     

业主委员会制度绩效影响因素分析

业主自主治理组织——业主委员会(HOAs)治理绩效出现差异的原因是一个重要的研究问题。对此采用强迫进入多元回归模型对同一地方的调查数据进行分析。结果发现:6个自变量共可以解释因变量78.30%的变异量;"小区规模"与业主委员会制度绩效成弱负相关关系,即小区规模越大,业主委员会制度绩效则越低,这种影响并不明显;一般社会资本对业主委员会制度绩效变异量的解释并不明显;"特殊社会资本"对业主委员会制度绩效的影响最大,其贡献系数0.678。     

国内外环境素养测评发展的比较研究

鉴于国内环境素养测评研究处于起步阶段,文章追溯了国内外环境素养测评理论发展的历史脉络,对比分析了国内外学者在环境素养测评研究方面的差距和不足,以期促进国内学者研究水平的提高,促进生态文明、环境友好型社会建设。     

区域农业可持续发展度评价——以环洞庭湖区为例

要实现区域农业可持续发展,首先就必须对其发展现状进行识别与判定,其次在理解区域农业可持续发展度的基础上,建立农业可持续发展度数学模型;并运用这一模型对环洞庭湖区1998—2006年农业可持续发展水平进行评价。最后得出结论:1998年农业处于不可持续发展的状态,其余各年洞庭湖区农业处于弱可持续发展状态;并针对今后环洞庭湖区农业可持续发展提出相关的对策建议。     

我国农业巨灾保险的发展瓶颈及破题之策

粘土稳定剂防膨率评价方法分析

防膨率是筛选和评价粘土稳定剂产品的重要指标。为了提高粘土稳定剂防膨率测定方法的准确性和重现性,结合实际检测工作,逐一分析了页岩膨胀仪法、具塞量筒法和离心法测定粘土稳定剂防膨率的误差来源和影响因素。结果表明:离心法可以减少仪器、环境、空白等方面产生的误差,测试实验条件下的相对标准偏差在1%以下。     

Using technology to improve the management of development impacts on biodiversity

The mitigation hierarchy (MH) is a prominent tool to help businesses achieve no net loss or net gain outcomes for biodiversity. Technological innovations offer benefits for business biodiversity management, yet the range and continued evolution of technologies creates a complex landscape that can be difficult to navigate. Using literature review, online surveys, and semi-structured interviews, we assess technologies that can improve application of the MH. We identify six categories (mobile survey, fixed survey, remote sensing, blockchain, data analysis, and enabling technologies) with high feasibility and/or relevance to (i) aid direct implementation of mitigation measures and (ii) enhance biodiversity surveys and monitoring, which feed into the design of interventions including avoidance and minimization measures. At the interface between development and biodiversity impacts, opportunities lie in businesses investing in technologies, capitalizing on synergies between technology groups, collaborating with conservation organizations to enhance institutional capacity, and developing practical solutions suited for widespread use.
