说提醒标记"你看"

在现代汉语中,"你看"可以充当提醒标记.它可独用表提醒,也可用来凸显因果关系和提醒状态、行为,其语用价值是提醒,一般地说,删去它在句法、语义上不会产生影响,但提醒的作用会随之消失.如果提醒的内容在说话人说出"你看"时是可以"看"到的,那么"看"可以重叠,"你"可以省略,反之则不可以.     

The organisational identity of science centres

This paper presents an empirically grounded mapping of the organisational identity that science centres in the UK are trying to carve out for themselves against the backdrop of developing organisational strategies and multiple external pressures, expectations and perceptions. I attempt this through a relational analysis that views the science centres’ organisational identity formation as constituted by and through a dialectic of autonomy and heteronomy that subtends the differential relationships science centres seek to cultivate vis‐à‐vis what I describe as the ‘parent’ fields – namely, science, formal education, the leisure industry and the museum. Science centres seek to stage a unique encounter of these four parent fields – an encounter that appropriates many significant dimensions of these fields without duplicating them. Through my analysis I hope to capture some of the key tensions and dilemmas that science centres and their organizational actors have to grapple with, the balancing acts they have to perform, and the complex organisational identity that is being forged in the process.     

社区照顾理念下的社区老年人日间照料中心建设

从社区照顾的理念出发,探讨了完善我国社区老年人日间照料中心的建设问题。认为我国社区老年人日间照料中心的建设应该以生活部分自理的半失能老年人为服务对象,以向这些老人提供生活照料、保健康复、精神慰藉服务为功能定位,依据街妙社区内的人口总数与老龄化程度综合确定建设规模,房屋建设内容应包括生活服务、保健康复、休闲娱乐和辅助用房等。     

Six-sigma for improving Top-Box Customer Satisfaction score for a banking call centre

Six Sigma process improvement methodology has been accepted globally across the service industry. In past one decade, the application and success of Six Sigma in Services is remarkable across Information Technology organisations, Hospitality firms, Government, Healthcare firms and Banking & Financial Sector. The aim of this paper is to explore the role of Six Sigma within call centres where the metric based environment complements the application of Six Sigma for process improvements. The article establishes the literature for the need for Six Sigma in call centre environment elaborating on customer facing metrics in addition to internal performance measures and highlighting the advantages of Six Sigma. A case study is presented in the second part of the article to study the DMAIC project management approach of Six Sigma for improving the Top Box Customer Satisfaction score of a Banking call centre. The literature identifies the possible opportunities for improving the performance of call centre metrics using Six Sigma. The project case study presented as part of the paper delivered a saving of USD 0.27 million to the bank, and is a classic example of how Six Sigma can bring bottom-line impact to an organisation. The article is limited to elaborate the advantages of Six Sigma in call centre environment, emphasising on its need and its compatibility to go along successfully with change acceleration and project management processes. Managerial implications and lessons learned are discussed alongside the concluding notes.     

分数布朗运动下带违约风险的可转换债券定价

应用均衡定价方法,考虑股票价格和公司资产价值服从分数布朗运动以及存在公司违约风险情况下的可转债定价问题;建立相应的可转债定价模型,采用拟鞅定价方法,得出了欧式看涨期权的显式解,进而得出了可转债定价公式;最后利用数值算例进行分析,结论表明公司违约风险、股票价格和公司资产价格的长程关联性是可转债定价时不可忽略的因素。     

沪市认购权证与其标的股票价格走势的Granger因果检验

运用G ranger因果检验的方法,检验沪市6只认购权证与其标的股票之间的因果关系。分析结果表明:在大样本条件下,认购权证与其标的股票之间存在单向的G ranger因果关系,权证的价格走势影响其标的股票的价格走势,说明从长期来看,认购权证发挥了其潜在的投资杠杆的作用,其价值发现与风险对冲功能在市场中得到实现;在小样本条件下,认购权证与其标的股票之间不存在显著的G ranger因果关系,表明短期内权证与其标的股票价格走势相互独立,市场中有可能存在对权证投机炒作,人为放大权证的投资风险,使权证背离其正常的投资价值。     

中国权证市场认购权证的价格偏误研究

使用Black-Scholes模型对中国权证市场上发行的认购权证进行了研究。研究表明,总体上权证的市场价格高于其模型价格80.38%(历史波动率参数的B/S模型)和140.50%(E-GARCH波动率参数的B/S模型);另一方面,随着时间的推移,市场价格和模型价格之间的偏误有减小的趋势。此外,研究还发现,2006年底至今,部分认购权证的市场价格不仅低于其模型价格,而且低于其价格下限。这似乎违反了无套利原则,但中国市场交易机制的限制(股票卖空限制、股票T 1交易机制)使得这一现象得以较长时间存在。当权证的市场价格低于其价格下限时,在特定的情况下,套利交易可以进行。     

Investigating call record data using sequence analysis to inform adaptive survey designs

Researchers have become increasingly interested in better understanding the survey data collection process in interviewer-administered surveys. However, tools for analysing paradata capturing information about field processes, also called call record data, are still not yet fully explored. This paper introduces sequence analysis as a simple tool for investigating such data with the aim of better understanding and improving survey processes. A novel approach is to use sequence analysis within interviewers, which allows the identification of unusual interviewer calling behaviours, and may provide guidance on interviewer performance. Combining the technique with clustering, optimal matching and multidimensional scaling, the method offers a way of visualising, displaying and summarising complex call record data. The method is introduced to inform survey management and survey monitoring. The method is hence informative for adaptive survey designs and will help to identify unusual behaviour and outliers and to improve survey processes. Sequence analysis is applied to call record data from the UK Understanding Society survey. The findings inform further modelling of call record data to increase efficiency in call scheduling.     

Standby Mothering: Temporalities,Affects, and the Politics of Mobile Intergenerational Care

ABSTRACT

In this paper, I showcase how left-behind mothers in the Philippines use digital communication technologies in delivering care to their overseas adult children in Melbourne, Australia. As part of a broader research project on transnational family life, the findings were drawn upon in-depth interviews, visual methods, a simple participant observation, and field notes taking and analysis. The study deployed a mediated mobilities lens, paying close attention to the different forces that shape the provision of intergenerational care through mobile device use. Building upon a critical analysis of the digitalization of intergenerational relationships in a transnational context, I coin the term ‘standby mothering.’ This conception encapsulates the femininized, ubiquitous, networked, and ambivalent intergenerational care practices that are experienced and negotiated by distant mothers. On the one hand, mobile device use enables left-behind mothers to deliver emotional and practical caregiving. On the other hand, everyday temporal conditions and technological barriers impede the provision of intergenerational care. Communicative constraints are constantly managed through various tactics, ensuring the sustenance of transnational relationships. By interrogating the contradictory outcomes of transnational caregiving, I underscore the politics of mediated mobilities in a digital society. Here, the mobilization of gendered, networked, and differential care practices is influenced by uneven structural and even socio-technological dimensions. Ultimately, this paper elucidates a critical stance on re-examining the provision of informal, gendered, and networked care practices.     

Effects of Uncertainty Aversion on the Call Option Market

This article examines the effects of uncertainty aversion in competitive call option markets using a partial equilibrium model with the Choquet-expected utility setup. We find that the trading volume of a call option is negatively affected by uncertainty aversion, whereas the price of the call is practically independent of it.
