“侧袋存放”机制在基金估值中的应用研究

对因突发事件临时停牌的股票和长期停牌的股票进行估值，可以借鉴国外对冲基金经常采用的“侧袋存放”机制。在公募基金行业中采取按允许赎回不允许申购、同时允许申购和赎回两种模式，具体实施机制各不相同。实施“侧袋存放”机制在基金持有人利益、IT系统支持、信息披露、费用计提等方面存在的一些难点。     

全面从严治党视野下的暂缓就业学生党员管理研究

暂缓就业党员管理工作是高校学生党建工作中的重要内容,全面从严治党对暂缓就业党员管理提出了新的要求.在新时期,暂缓就业党员呈现出量少质优等新特点,高校党组织可以通过建立专兼结合的暂缓就业党员管理干部队伍、做好暂缓就业党员的分类管理和教育引导、建立有关管理工作制度、促进暂缓就业党员发挥先锋模范作用等具体措施以实现从细从严的管理目标.     

Air route suspension: The role of stakeholder engagement and aviation and non-aviation factors

This study provides insight into how aviation and non-aviation factors affect the decision to suspend air routes. Using examples from Australian domestic routes, the paper analyses the business relationships and negotiation processes followed by airports, airlines, and destination management organizations (DMOs) to avoid air route suspensions. Data were collected through semi-structured interviews with key aviation and tourism stakeholders directly impacted by suspended routes. The outcomes of this paper demonstrate that while most of the major reasons for air route suspension in Australia are mentioned in existing literature and are linked to demand, other factors have not previously been deeply investigated, including how stakeholders can be involved to avoid air route suspension. The paper also explores and identifies strengths and weaknesses in the relationship among airlines, DMOs and airports.     

城乡土地增减挂钩政策的现实困境及可能出路

城乡土地增减挂钩政策的实施,凸显了当前农村土地制度的焦点问题。然而,这一政策却在耕地保护、城市化、土地规模化经营、农村和农民权益保护方面遭遇了一系列难题。究其原因,乃是由于其未能关照＂农村稳定、农业发展、农民权益＂的三农问题多元价值体系,且未经系统考量和全面规划,并受利益驱动陷入了冒进的状态。有鉴于此,走出现实困境,应调整其基本指导思想,以维持农村稳定为基础,以维护农民权利,促进农村发展为根本,并着力完善管理监督机制。

超细全尾砂连续充填工艺技术的研究与开发

冬瓜山铜矿采用阶段空场嗣后充填采矿法,设计生产能力13000t/d,充填能力3850m3/d,年需充填量120万立方。矿块分二步骤回采,即先采矿房,后采矿柱,为控制地压活动,采用隔三采一和隔一采一的采矿顺序。在矿石中有25%的难选矿石,为提高选矿回收率因此矿石粒级细且尾砂含硫较高,若用分级尾砂充填矿山充填材料缺口很大,同时在充填料浆中含有一定的有害气体。因此采用全尾砂高浓度连续充填和选择适宜的高强度充填胶结材料是冬瓜山铜矿实现安全文明生产,保证矿山生产能力的前提。

Corporate governance and incidences of listing suspension by the JSE Securities Exchange of South Africa: An empirical analysis

We examine the association between corporate governance structures and incidences of listing suspension from the JSE Securities Exchange of South Africa. Using a matched-pairs research design, we compare 81 firms suspended between 1999 and 2005 to an equal number of control firms matched in terms of time, size and industry. Employing a conditional logistic model, we find that the likelihood of suspension is higher in firms with a smaller proportion of non-executive directors, without an audit committee, and with greater block-share ownership and higher gearing (i.e. leverage). Further analysis splitting block-share ownership into institutional and non-institutional investors provides mixed results. While we find a positive association between suspension and non-institutional investors, we observe no association with institutional investors. No association is detected for board size, role duality, directors' share ownership, auditor quality and return on assets. Given the paucity of studies examining listing suspension from stock exchanges and corporate governance mechanisms, these findings contribute to the literature. Additionally, the dearth of research on corporate governance in developing countries suggests that our findings have important implications for policy makers in these countries as they endeavor to improve corporate governance.
