情景分析在商业银行风险管理中的应用

高级计量法(AMA)是商业银行操作风险计量方法的发展趋势,损失数据的数量和质量影响着AMA模型计量结果的准确性,进而决定了银行操作风险资本要求水平。作为一种前瞻性的风险管理方法,情景分析可以弥补银行内部损失数据不足的问题,同时综合专家经验,在一定程度上克服了VaR模型本身的缺陷。在探讨情景分析方法论的基础上,本文以部分国际同业的实践为例介绍了情景分析的应用流程,并指出国内银行要实施情景分析,必须重视并积极推进历史损失数据的积累,对数据的应用应循序进行,并不断加强对分析人员的培养。

晚期癌症患者麻醉药品用药情况分析

目的：探讨晚期癌症患者麻醉药物使用情况。方法选取我院2013年晚期癌症患者门诊麻醉药品处方共1945张,年消耗麻醉药品量6144片（支）,根据麻醉药品限定日剂量（DDD）,确定用药频度（DDDs）,对我院麻醉药物的使用情况进行分析研究。结果按照 DDDs 排序,麻醉药品中数量最多的属于哌替啶注射液,其一年消耗量最多,使用频率最高,硫酸吗啡缓释片以及可待因片使用数量较少。哌替啶注射液的药物利用指数（DUI）为3.75,可待因片以及硫酸吗啡缓释片的 DUI 在1.0以下,这两种药物的使用方法和剂量大致合理。结论晚期癌症患者使用麻醉药品还存在不合理性,因此,医护人员应进行宣传教育,全面推行长效口服制剂吗啡控制片,同时还要严格限制哌替啶注射液的使用,进而使患者生活质量明显提高。     

Dispersed positioning in portfolio analysis

In this article we address what may be called the requisite variety imperative: for a firm to succeed, the complexity, subtlety, and speed of its responses must match the urgency, subtlety, and complexity of the environment. We suggest that portfolio analysis is not adequate to those challenges and propose a means of enhancing subtlety and complexity, thus making a firm's decision processes more responsive to the environment while realigning its view of the outside world with the realities of the environment.     

Time,Price, and Advanced Booking of Hotel Rooms

ABSTRACT

The effectiveness of revenue management systems has diminished in recent years due to the systems' inability to address the increasing complication of online deal-seeking behavior. To restore their efficiency, one must first understand the changes in advanced-booking behavior and their implications. This study expands the consumer booking model by addressing the impact of time-before-the-date-of-stay and exploring the implication for the hotel's pricing/marketing strategies. The findings underscore the urgent need for empirical research on timing by showing that the predictions of the advanced-booking model, and consequently the effectiveness of RM systems, depend on the actual patterns over time.     

Advance transit oriented development typology: case study in Brisbane,Australia

Internationally, transit oriented development (TOD) is characterised by moderate to high density development with diverse land use patterns and well connected street networks centred around high frequency transit stops (bus and rail). Although different TOD typologies have been developed in different contexts, they are based on subjective evaluation criteria derived from the context in which they are built and typically lack a validation measure. Arguably there exist sets of TOD characteristics that perform better in certain contexts, and being able to optimise TOD effectiveness would facilitate planning and supporting policy development. This research utilises data from census collection districts (CCDs) in Brisbane with different sets of TOD attributes measured across six objectively quantified built environmental indicators: net employment density, net residential density, land use diversity, intersection density, cul-de-sac density, and public transport accessibility. Using these measures, a Two Step Cluster Analysis was conducted to identify natural groupings of the CCDs with similar profiles, resulting in four unique TOD clusters: (a) residential TODs, (b) activity centre TODs, (c) potential TODs, and (d) TOD non-suitability. The typologies are validated by estimating a multinomial logistic regression model in order to understand the mode choice behaviour of 10,013 individuals living in these areas. Results indicate that in comparison to people living in areas classified as residential TODs, people who reside in non-TOD clusters were significantly less likely to use public transport (PT) (1.4 times), and active transport (4 times) compared to the car. People living in areas classified as potential TODs were 1.3 times less likely to use PT, and 2.5 times less likely to use active transport compared to using the car. Only a little difference in mode choice behaviour was evident between people living in areas classified as residential TODs and activity centre TODs. The results suggest that: (a) two types of TODs may be suitable for classification and effect mode choice in Brisbane; (b) TOD typology should be developed based on their TOD profile and performance matrices; (c) both bus stop and train station based TODs are suitable for development in Brisbane.     

Organizational Ambidexterity and the Emerging‐to‐Advanced Economy Nexus: Cases from Private Higher Education Operators in the United Kingdom

The expansion of advanced‐market economy (AME) firms into emerging‐market economies (EME) is well documented. In recent decades, EME companies have moved increasingly into AMEs, especially within the manufacturing sector, as well as other important AME sectors such as higher education (HE). However, the latter have received less attention. This study conducts an in‐depth qualitative analysis of two EME HE organizations operating in the international HE sector in London. The argument applies a theoretical framework of organizational ambidexterity with which to examine the contexts and complexities in collaborations between EME‐HE and AME‐HE firms. These argument surfaces, inter alia: differing dynamics in relation to institutional frameworks and sense making; myopic internationalization; tensions regarding organizational reputation, place, partner, and product legitimization; unfulfilled reverse innovation and “explorative‐pull” phenomena. Overall, the article develops novel conceptual frameworks of practical relevance, which inform EME‐AME firm collaborative operations in AME settings. © 2016 Wiley Periodicals, Inc.

Modeling risk in arbitrage strategies using finite mixtures§

We revisit the problem of calculating the exact distribution of optimal investments in a mean variance world under multivariate normality. The context we consider is where problems in optimisation are addressed through the use of Monte-Carlo simulation. Our findings give clear insight as to when Monte-Carlo simulation will, and will not work. Whilst a number of authors have considered aspects of this exact problem before, we extend the problem by considering the problem of an investor who wishes to maximise quadratic utility defined in terms of alpha and tracking errors. The results derived allow some exact and numerical analysis. Furthermore, they allow us to also derive results for the more traditional non-benchmarked portfolio problem.
