Media constructions of risk: a case study of the Stainforth Beck incident

In October 2000 two schoolgirls were swept away from their party whilst ‘river walking’ in Stainforth Beck near Settle in North Yorkshire. The paper examines this incident with reference to media coverage of the events at the time and the subsequent reportage. The discussion contributes to the debate concerning the appropriateness of an agenda of broadening education. We argue from a position that supports the principle of breadth, particularly when such activities are part of adventure education with its propensity to engage with outdoor risk settings. Whilst lessons must be learnt from such a tragic incident, it is important that outdoor professionals continue to disseminate the positive potential of adventure in order to offset the negative messages concerning risk promoted by the media in general.

农村信用社是否应当加入存款保险制度：博弈论视角

文章从博弈论角度论证了金融机构加入存款保险制度的必要性,并通过调查问卷、实地调查等方式,对山东省A市农村信用社加入存款保险制度的影响进行了实证分析。分析结果表明,加入存款保险制度不会引起农村信用社存款大规模流失,保费征收短期会增加农村信用社的经营成本、降低营业利润,但不会影响农村信用社的长期稳健经营,亦不会对当地金融稳定形成冲击。     

Signalling with official interest rates: the case of the German discount and lombard rate

A major characteristic of the operating procedure of the European Central Bank (ECB) is its reliance on standing facilities. It is intended that the official rates on those facilities also serve the function of signalling. The case of Germany, where the Bundesbank followed a similar signalling strategy, is analysed. In particular the paper investigates whether announcements of official interest rates provide information not already contained in other policy measures and whether the resulting revisions of expectations are efficient. Significant differences are found between signalling in the case of increasing and decreasing interest rates.     

构建我国煤矿安全生产保障体系的思考

我国煤矿安全事故近年频繁发生，煤矿安全生产成为国内外关注的重要热点问题。本文通过对煤矿安全生产过程特点与规律的总结发现：我国煤矿安全事故发生的根本原因在于没有构建一套综合的、系统的、严密的、持续改进的煤矿安全生产保障体系。为此，本文从我国煤矿安全生产的思想、制度、监察、技术、全员和全过程等方面出发．初步构建了一套综合的、系统的、严密的、持续改进的煤矿安全生产保障体系与运行模式．并提出了我国近期遏制煤矿安全事故的制度措施。     

Corporate Data and Future Cash Flows

Abstract:   This article examines the ability of current accounting data to explain future cash flows for UK firms, as disclosed under FRS1 (1991). Rather than examining price data — from which cash flow implications have to be inferred — we follow the more direct approach used in several recent US studies, in which actual future cash flow data are examined. Specifically, our methodology is a development of the OLS regression framework employed by Barth et al. (2001) . We provide a replication of their main OLS analysis, and then extend this to deal with fixed effects and time trends in the levels of cash flow data. Our study finds that the disaggregation of earnings into cash flows and accruals, generates superior explanatory power with regard to future cash flows.     

Changes in airport operating procedures and implications for airport strategies post-COVID-19

Covid-19 is demanding a lot of changes in the realm of our daily lives. The aviation industry is also facing unprecedented changes in the management environment. Financial tensions across the sector are rising. This study suggests that the airport strategy's direction focusing on commercial revenue management. After Covid-19, safety and hygiene will be the top priority. As a result, changes in airport operating procedures are inevitable. The most noticeable difference will be the strengthening of the verification process for passengers' health conditions. Dwell time increase can be the by-products. This study identifies a dwell time increase has a more significant impact on increasing the existing purchasers' spending than creating new buyers. Airport operators can introduce a service differentiation perspective, such as a dedicated service, to utilize the current buyers' dwell time more faithfully. Also, the rise of online channels requires airport operators to change sales strategies, reinforcing emotional promotion to stimulate impulse buyers' willingness-to-buy. Before Covid-19, there was little effort to reconcile operation policies and commercial revenue despite the growing importance of revenue management. However, now it is time to change. Pre-Covid-19, passengers were advised of using off-airport processes, such as online check-in and mobile boarding passes. Now, getting passengers to the airport quickly and securing their dwell time can be financially more beneficial. It is necessary to incorporate the commercial revenue perspective into operation policies post-Covid-19 actively. Our finding indicates that even a passenger with solid purchasing power may lose the purchasing intention when assigned to an unfavorable gate or terminal. Airport operators need a better understanding of passenger and flight characteristics when determining operation policy, such as gate allocation or membership services.

铁路项目评价中运营成本的探讨

将《铁路建设项目经济评价方法与参数》与《铁路建设项目经济评价办法》（第二版）中运营成本的确定方法进行比较,指出《方法与参数》的先进之处在于应用了＂有无对比＂原则、引入了作业成本法,并合理地确定成本计算区间;指出《方法与参数》尚存运营成本归集遗漏、＂有无对比＂原则应用不彻底致使成本内部口径不一致的问题;建议在运营成本确定时要完善作业细分,全面贯彻有无对比原则;同时,应及时更新运营成本费率,充分发挥作业成本法的成本管理功能。
