铁路退票险费率计算模型构建研究

旅客在办理退票业务时铁路收取阶梯退票费,所退票额可能无法再次售出,对旅客和铁路双方都存在潜在风险。铁路退票险是一种较好的保险服务,能够分担旅客退票和铁路客运资源在合同约定履行期间内的违约风险,创新客运主营业务服务。借鉴交通运输行业的非寿险费率计算方法,构建铁路退票险费率计算模型。通过分析退票业务,识别退票险影响因素,计算退票险费率,进行退票险知识库闭环管理,研究结果表明依据广义线性模型方法计算的纯保费与传统法差别不大,但可以节省较多的时间,因而使用广义线性模型方法计算铁路退票险费率更为合理有效,有助于加快铁路退票险费率的出台。

From Storyville to Bourbon Street: Vice,Nostalgia and Tourism

This paper contrasts New Orleans' former red-light district, Storyville, and contemporary Bourbon Street, New Orleans' major tourist attraction, to illustrate how history has been revived into a tourist product to maintain the city's appeal as a destination. Nostalgic images are developed for tourism consumption of heritage destinations. The images are idealised versions of the past that alter the authenticity of the historic context from where they came. On Bourbon Street, the Storyville district is utilised as an image to elicit nostalgia of a period no longer actively incorporated into New Orleans's cultural fabric. Through a qualitative analysis of the tourism communication materials, Bourbon Street is analysed as a nostalgic representation of Storyville and its once acceptable vice activities. Activities such as public sexuality, music and dancing, and shopping are ways in which tourists can experience the once legal red-light district. It is argued that what is presented to tourists is a commercial image of the past and its reputation, rather than an accurate portrayal of New Orleans either yesterday or today.     

High-speed rail and air transport competition in Western Europe: A supply-oriented perspective

Increasingly air transport growth raises the question of its impact on the environment. Public authorities and researchers are relying more and more on high-speed trains (HSTs), whose efficiency is supposed to lead to a modal shift from airplanes. However, most transport studies focus on the evolution of demand rather than supply, although it is basically the latter that determines environmental damage. In light of this fact, this paper aims to compare the overall dynamics in the supply of air transport in Europe compared to the HST supply and to examine empirically five city-pairs. The development of high-speed rail remains limited compared to the increase of air services. For a given city-pair, the decline in the number of flights depends on various conditions, including length of the HST journey and the strategies adopted by the airlines. Some carriers reduce their supply in terms of the number of seats but increase the number of flights in order to compete more effectively with the HSTs. Moreover, the competition between low-cost airlines and HSTs should be kept in mind and re-examined in a few years.     

‘Why Did MH17 Crash?’: Blame Attribution,Television News and Public Opinion in Southeastern Ukraine,Crimea and the De Facto States of Abkhazia,South Ossetia and Transnistria

ABSTRACT

Shock events are often pivotal moments in geopolitics and objects of intense disagreement among conflicting parties. This paper examines the downing of a Malaysia Airlines passenger jet over eastern Ukraine in July 2014 and the divergent blame storylines produced on Russian and Ukrainian television about the event. It then examines results of a question asking why MH17 crashed in a simultaneous survey conducted in December 2014 in six oblasts in Southeastern Ukraine, Crimea, and the de facto states of Abkhazia, South Ossetia and Transnistria. An analysis of the surveys shows that blame attribution was driven more by television viewing habits than by any other factor.     

Meditation as a kind of leisure: the similarities and differences in the United States

Meditation has been shown to be a cost-effective means to help individuals reduce stress, alleviate anxiety and depression. Similarly, leisure has been found to reduce stress, improve mood and contribute to overall health and well-being. The similarities and differences in outcomes between meditation and leisure suggest that a comparative analysis may determine if and how experiences and outcomes of meditation may be similar to and different from those of leisure and provide deeper insights into the ways in which both can contribute to improved quality of life. The purpose of this study is to examine the similarities and differences in meditation and leisure as perceived by a range of individuals engaging in meditation. Results indicate that meditators experience stress reduction, emotional balance and an enhanced quality of life during both their leisure and meditation. Many of the positive experiences and outcomes derived from meditation render it very similar to leisure. Nevertheless, meditation and leisure also differ in several important ways.     

Analysis of the Expected Resources of Copper Scrap

In this article, the expected resources of copper scrap in the Russian Federation have been analyzed, and their amounts and use through 2035 have been estimated. The conclusion on reducing the supply of copper scrap resources in the country in the mid-term prospects as a result of the change in based on the scrap generation and notable decline in the copper consumption in the country since the 1990s has been explained. In addition, the possible presence of uncollected scrap reserves, which may ultimately affect the operations of producers of copper and copper-containing products and lead to increased competition over the raw materials on the market, has been assessed and analyzed.     

On the Structure,Dynamics, and Use of the Asset Share in the National Wealth

In this article, the share of assets in the national wealth is taken as the object of analysis and forecast. The dynamics, structure and use of the basic elements of Russia’s productive assets—natural capital (energy inputs), human capital, and active fixed assets—are analyzed. It is shown that the natural capital will inevitably be replaced by human capital in combination with the asset share in fixed capital, and that the economy in the coming transition period (2018–2030) will necessarily transform to an innovative growth model.The annual balances of changes in the components of the assets in the national wealth for 2012–2016 are developed. The impact of the crisis is estimated. Some promising directions for using the accumulated human capital together with the asset share in fixed capital for a transition from a resource-based to an innovation model of Russia’s development are considered and substantiated.

Search Costs and Re-Employment Wage Gains for Displaced Workers

Involuntary job separation generally leads to lower re-employment wages. However, 20–30 percent of displaced workers experience re-employment wage gains. Theoretically, workers with higher search costs accept jobs when the marginal benefit of search is relatively high. When displaced, these workers experience wage gains because they are forced into additional search. Using data from the Displaced Worker Survey, we find that higher search costs (measured as the wage residual from the predisplacement job) are associated with higher re-employment wages.
