Tidal river management for sustainable agriculture in the Ganges-Brahmaputra delta: Implication for land use policy

The tidal river management (TRM) approach is an indigenous management practice in the Southwest part of the Ganges-Brahmaputra delta in Bangladesh. This approach has a high potential for extending area under agriculture with a positive impact on sustainable production and consequently on sustainable land use planning. Until recently, no studies provide a quantitative assessment on agricultural benefits of TRM operation. In this study, we aim to assess the benefits of TRM operation by using innovative approaches such as comparing land use change, agricultural production and economic cost-benefit analysis for two scenarios (with and without TRM) in the Hari-Teka-Bhadra catchment. We found that the financial benefit of TRM operation was 85.5 million US dollar per year from the agriculture sector. The results are useful for promoting land use policy through TRM approach in achieving greater sustainability in the area.     

可持续性转型治理的重建和解构

本文以转型管理为重点，回顾了对可持续性转型的一些批判和质疑。虽然这些质疑促进了理论进展，但潜在的认识论问题依然存在。本文阐述了对转型管理及其隐含复杂性范式的一些批判是如何建立在对复杂性的解构主义认识上，这对复杂系统在何种程度上可以被影响朝所期望的方向发展提出了质疑。对转型管理的批判需要认识如下几点：（1）转型管理需要解构力（迄今未充分说明）；（2）同时具有“超越”解构主义的明确追求。为此，本文提出了一种“重构方法”作为转型研究的认识论基础，这种重建方法分为三个方面：（1）超越 “是”和“应该是”，倾向于“可以是”；（2）诠释性和自反性研究；以及（3）可持续性的“实践智慧”。     

苹果种植适度规模经营研究*——以陕西省白水县为例

［目的］分析苹果种植户经济效益的影响因素，研究适合苹果种植的农地规模，提高白水县果农苹果种植的经济效益，探索苹果产业可持续发展经营模式，丰富以果蔬为主的集约型经济作物适度规模经营研究范围。［方法］采用实地调研法，对陕西省白水县230户苹果种植户进行问卷调查，从收益最大化角度，运用柯布道格拉斯生产函数对苹果生产的投入产出进行经济分析，构建收益最大化模型，测算白水县苹果种植的最适规模，分析苹果产量的影响因素，探讨劳动力投入、资本投入、有效面积和果农参加技术培训对苹果产出的影响和贡献程度，并用钱克明等对农地的适度经营规模定义进行结果验证，最后提出合理的政策建议。［结果］经过分析，在同等技术条件下，劳动力投入、资本投入、有效种植面积、果农参加技术培训的次数对苹果的产出具有显著影响。以农户收益最大化模型测算的劳均经营规模面积在0363~0447hm2（544~670亩）的可视为适度规模，根据钱克明等的适度经营规模目标值的计算，其函数解为550，在适度规模范围之内。即户均农地适度经营规模0751~0966hm2（1127~1449亩）。目前白水县苹果生产处于规模报酬递减阶段，农资市场环境和劳动力投入方面仍然存在短板。［结论］建议扩大白水县户均苹果种植面积，提升土地经营效益，从而增加果农收入，支持农业新型经营主体发展，创新发展模式； 建立新型职业农民培育体系，促进苹果种植户剩余劳动力转移，提高农民非农收入； 从法律上规范农村地区农资市场环境； 规范农户绿色生产经营行为，提高化肥的使用效率和开发新的高效肥料； 政府引导农地的适度规模集中，整合资源进行规模化、现代化的经营。     

A practical road map for assessing cyber risk

The increase in interconnectivity and developments in technology have caused cyber security to become a universal concern. This paper highlights the dangers of the evolution of cyber risk, the challenges of quantifying the impact of cyber-attacks and the feasibility of the traditional actuarial methodologies for quantifying cyber losses. In this paper, we present a practical roadmap for assessing cyber risk, a roadmap that emphasizes the importance of developing a company and culture-specific risk and resilience model. We develop a structure for a Bayesian network to model the financial loss as a function of the key drivers of risk and resilience. We use qualitative scorecard assessment to determine the level of cyber risk exposure and evaluate the effectiveness of resilience efforts in the organization. We highlight the importance of capitalizing on the knowledge of experts within the organization and discuss methods for aggregating multiple assessments. From an enterprise risk management perspective, impact on value should be the primary concern of managers. This paper uses a value-centric/reputational approach to risk management rather than a regulatory/capital-centric approach to risk.     

自然资源资产管理：理论逻辑与改革导向

研究目的:针对自然资源资产管理的理论诠释不清、改革导向不明、自然资源的资产属性尚未充分体现等问题,本文立足新时代党和国家机构改革背景,分析自然资源资产管理的理论逻辑,明确未来自然资源资产管理的改革方向。研究方法:文献研究法,综合分析法。研究结果:新时代自然资源资产管理应当基于"权利—价值—经营—管理"的理论逻辑体系框架,其中自然资源资产权利应当包含自然资源资产所有权、资格权、使用权和管理权等对象内涵,以完整、明晰和稳定作为权利实现要求;自然资源资产价值显化应当基于生态、经济等价值的全面认知,针对不同资产类型分类采用不同价值评估方法,完善市场培育、价值调节和公平分配机制;自然资源资产经营既要保障粮食安全、生态安全和规避可能风险,又要实现高品质利用,因而应当以底量保安全,以存量、数量、质量、差量和流量保协同,优化完善编制资产负债表;自然资源资产管理则应当打破自然资源资产管理割裂的现状,实现系统统一管理并建立全平台、全过程、全资源和全空间的综合监督机制。研究结论:自然资源资产管理应以"三维立体多权化"、"生态价值具象化"、"安全品质六量化"和"系统监管综合化"为改革导向,以期全面推进未来多维、绿色、高效、安全、品质、有序的自然资源资产管理方式的切实实现。     

CEO internal experience and voluntary disclosure quality: Evidence from management forecasts

Internally‐promoted CEOs should have a deep understanding of their firm's products, supply chain, operations, business climate, corporate culture, and how to navigate among employees to get the information they need. Thus, we argue that internally‐promoted CEOs are likely to produce higher quality disclosure than outsider CEOs. Using a sample of US firms from the S&P1500 index from 2001 to 2011, we hand‐collect whether a CEO is hired from inside the firm and, if so, the number of years they worked at the firm before becoming CEO. We then examine whether managers with more internal experience issue higher quality disclosures and offer three main findings. First, CEOs with more internal experience are more likely to issue voluntary earnings forecasts than those managers with less internal experience as well as those managers hired from outside the firm. Second, CEOs with more internal experience issue more accurate earnings forecasts than those managers with less internal experience as well as those managers hired from outside the firm. Finally, investors react more strongly to forecasts issued by insider CEOs than to those issued by outsider CEOs. In additional analysis, we find no evidence that these results extend to mandatory reporting quality (i.e., accruals quality, restatements, or internal control weaknesses), perhaps because mandatory disclosure is subjected to heavy oversight by the board of directors, auditors, and regulators. Overall, our findings suggest that when managers have work experience with the firm prior to becoming the CEO, the firm's voluntary disclosure is of higher quality.     

New development: Fiscal reform in South Korea: looking back and moving forward

ABSTRACT

At first glance, it seems that South Korea’s three fiscal systems (mid-term expenditure framework, top-down budgeting, and performance management) function well. However, each fiscal system operates separately and they are inefficient because they follow past practices. This article explains what the problems are and how to overcome them.     

Personality in context: effective traits for expatriate managers at different levels

The purpose of this article is to assess how management level as a contextual factor interacts with personal characteristics in predicting expatriate performance. In particular, we focused on proactive personality (the individual’s disposition to change the organizational environment) and self-control (the individual’s disposition to change oneself to fit the organizational environment). Surveying 307 business expatriate managers in China, we hypothesized that in relation to work outcomes, the effect of proactive personality would be stronger for CEOs while the effect of self-control would be stronger for non-CEOs. We found both proactive personality and self-control to have favorable effects on our performance indicators: job performance, effectiveness, and time to proficiency. In line with our prediction, we also found the effect of proactive personality on job performance to be stronger for CEO expatriates while the effect of self-control on performance was stronger for non-CEO expatriate managers.
