上海股票市场波动实证性研究:2001--从交易方式角度透视

我国股票市场上的交易方式有两种,即集合竞价和连续竞价,交易方式的差异会对股价的波动性产生影响,而市场的波动性对股票市场而言是双刃剑,因此从交易方式角度探求股市的适度波动成为理论工作的一个重心.本文以上海股票市场为研究对象,针对2001年的全部交易数据进行实证研究.结果表明,集合竞价形成的开盘价格收益率的方差大于连续竞价形成的收盘价格收益率的方差,其原因在于集合竞价与连续竞价相比,其交易过程的透明度差和交易指令具有不可更改性,据此,从交易制度上提出政策建议.

The bumpy road to ‘becoming’: capturing the stories that teenage mothers told about their journey into motherhood

Understanding the experience of women who become mothers during their teenage years is central to ensuring that the support that is offered is appropriate to meet their needs. This paper reports on a small part of a larger ethnographic study that captured the lived experience of young mothers who were between the ages of 16 and 19 years that potentially typifies and illuminates the experiences of young women who become mothers in their teenage years. By collecting data from narrative interviews as well as participant and non‐participant observations over an extended period of time it was possible to identify how the young women experienced a range of difficulties as they made their transition into motherhood. Drawing on the findings, this paper argues that this transition for teenage mothers can be significantly different from the experience of older mothers, and it identifies the importance of appropriate support to mediate the challenges that they face. Understanding the young women's journey to ‘becoming’ is critical when planning services because if their experience of support is negative, it can lead to increased levels of maternal stress and reluctance to engage with support services.     

“保险性质”期权定价模型及其应用研究

针对传统期权风险大的特点，以欧式看涨期权为基础提出一种风险小、价格低的特殊期权——“资产保险性质”期权，即期权买者出于对标的资产的保险目的，签订期权合约后，若标的资产价格上涨，期权买者将其一部分收益支付给期权卖者，以这种交易方式对传统期权产品进行改进并重新定价，从而得出“保险性质”期权及其定价公式。针对和传统期权的价格变动状况，用Excel进行了模拟比较，证明了“保险性质”期权价格低（吸引期权买者）、风险小（利于期权卖者的风险控制）的特点。“保险性质”期权产品的开发将对我国各类金融市场的建设具有现实意义。     

论郑临川古典诗词的精神向度

郑临川先生的古典诗词在理想追求、爱国情怀、社会责任、读书治学等方面都深深地打上了时代烙印。他的诗词大都是人生旅程的写照,在对时势无奈的痛苦中发出感时哀世之吟,从而抒怀言志,表达强烈的爱国之情;其诗歌无论纪游、赠别、思乡、怀人,多呈离乱的悲凉心境,折射出知识分子发自内心深处的时代感怀。无论是刚接触现实融入社会的歌吟之作,还是表现漂泊流离、前途渺茫的无端伤感,抑或后来反映教书育人的心中吐蕊,以及人生起伏的情感激荡,无不透露着自觉而强烈的社会责任。老一辈知识分子那种坚定的爱国热情和自觉的社会责任,正是中华民族世代薪火相传的精神认同。     

Town Centre Management: Outlook from Portugal

In the last two decades, the Portuguese Government has responded to the decline of centres of commerce. In this paper, we analyse the three different experiences of town centre management (TCM) schemes developed in Portugal since the turn of the millennium. The first two stages were developed using public sector initiatives and their impacts were limited. The third stage is still under way and is composed of private projects created by local business owners. Taking Lisbon as a case study for this third stage we conclude that these projects have become a pro-active means of intervention in Portuguese town centres.

Navigating health care: brokerage and access for undocumented Latino immigrants under the 2010 Affordable Care Act

ABSTRACT

Brokerage is a prominent mechanism that explains access for Latino immigrants to many American institutions. However, few studies examine the dual nature of brokerage in answering questions on access to health care for undocumented Latino immigrants. The growing importance of Federally Qualified Health Centers (FQHCs) and ethnic navigators connecting immigrants to health care under the 2010 Affordable Care Act calls attention to the duality of brokers and its role in access. The study draws from 44 in-depth interviews with providers, clinic directors, navigators, and immigrant patients and two years of fieldwork in FQHCs in California’s San Francisco Bay Area (2011–2013). Results show that brokers enable access through coaching and myth-busting but they also hinder it through scrutiny and bureaucratic filtering. The widespread dependence on brokerage, I argue, leads to ersatz brokerage, such as when providers navigate the health-care system for the undocumented without the appropriate linguistic resources or coordination. Furthermore, the study shows that the duality in brokerage generates misinformation, churning, and alienation. Understanding the relational processes that both include and exclude vulnerable populations from needed services enhances theories of immigrant integration and can help design more efficient policies and address inequalities related to documentation status.     

Discourses of service user involvement in meeting places in Norwegian community mental health care: a discourse analysis of staff accounts

In previous research, meeting places have been favourably addressed by service users, but they have also been contested as exclusionary. In this participatory explorative study, we sought to perform a contextual analysis of meeting places in Norway based on a discourse analysis of three focus group discussions with 15 staff members. We asked the following question: how do meeting-place employees discuss their concrete and abstract encounters with service users and their experiences? We focused on service user involvement, which was largely analysed as neoliberal consultation and responsibilisation. Service users were positioned as resisting responsibility trickling down and defending staffed meeting places. Social democratic discourse was identified in the gaps of neoliberal discourse, which is noteworthy given that Norway is a social democracy. This relates to global concerns about displacements of democracy. We suggest that meeting places appear to hold the potential for staff and service users to collaborate more democratically.     

Global economy of signs and selves: A view of work regimes in call centers in the Philippines

Reflecting on the global nature of third-party offshore call center and its implications on the agent, this piece is an account of the researcher's own experience, observations, and interactions as a call center worker. Using the theoretical frame Global economy of signs and selves, weaving ideas from Scott Lash and John Urry, Pierre Bourdieu and Erving Goffman, the study looks at some dimensions and conditions of global service work experienced by Filipino agents. With the relocation of accounts offshore, call centers in the Philippines have given rise to a growing section of society required by the imperatives of their work to “defy” time and space, synchronizing their cycles and routines according to the rhythms and cycles of a distant social dimension and the imperatives of globalized production. Although relocation has allowed firms to reduce costs and make use of cheaper labor, the distance traversed by this new call center platform comes with some hidden costs, borne by workers, who may themselves take these other forms of work they deliver for granted. Highlighting under-emphasized, undervalued and misrecognized aspects of call center work, the study attempts to link the global, the local and the personal, while emphasizing the social and symbolic work involved in call center production.
