鲍照赋与魏晋赋

鲍照赋从情感倾向、风格特点、题材内容到表现技巧,实受魏晋赋的影响:他的赋具有建安风骨的特征,其咏物赋,继承了魏晋咏物赋擅长抒情说理的特点,并有所发展,而其抒情小赋则继承了魏晋抒情小赋的感伤传统。     

赠与人"撤销权"的厘定与赠与制度的基本构造

理论上对赠与人撤销权制度的认识存在着极大的分歧.赠与人的撤销权为民法撤销权体系中的特例之一,它实际上应被称为"撤回权",并具有后悔权的意义,在性质上更类似于解除权.赠与人的任意撤回权与赠与合同的诺成性攸关,是旨在弥补赠与被立法确认为诺成合同后对赠与人要求过苛的弊端而设计的救济性手段.任意撤回权的行使虽为法定,但赠与人亦应赔偿受赠人因此所遭受的信赖利益损失,且其责任基础不是一般所认为的缔约过失责任而应是违约责任.     

论行政许可中的听证制度

《行政许可法》将听证制度纳入有利于保护当事人的利益,但关于听证的规定也存在亟待完善之处,如听证事项没有具体化,听证范围过小,依职权听证的性质难以确定等,这些都值得我们进一步研究和探讨。     

论福克纳小说《熊》的生态伦理观念

《去吧,摩西》中的短篇小说《熊》在看似简单明晰的文本背后,蕴含着丰富的生态伦理观念。尤其是带有强烈议论性质的第四部分,其叙事不仅暗示了小说审美风格的转变,而且体现了福克纳小说人学救赎观念与生态伦理思想的交汇融合。强调自然生态环境是人存在的重要组成部分,表达对自然生态环境宗教般虔诚的敬畏情怀构成了小说《熊》的生态伦理观念的第一层内涵。强烈批判人类中心主义思想和现代工业文明对荒野和自然的破坏,深化宗教人学意义上的罪恶与救赎的观念构成了《熊》生态伦理观念的第二层内涵。此外,《熊》还传达出了福克纳强烈的拯救与重建人的本质的愿望。     

建立我国经济诉讼特别程序的思考

经济法律规范缺乏可诉性已是法学界公认的事实,单对现有制度的修修补补已无法解决这一问题.因此,应参照国外的成熟制度,在现有的制度上创新,建立我国的经济诉讼特别程序.为保证该程序发挥应有的作用,必须合理设计具体的操作方案并防止诉权的滥用.     

A semi-parametric method for estimating the beta coefficients of the hidden two-sided asset return jumps

ABSTRACT

We introduce a new methodology for estimating the parameters of a two-sided jump model, which aims at decomposing the daily stock return evolution into (unobservable) positive and negative jumps as well as Brownian noise. The parameters of interest are the jump beta coefficients which measure the influence of the market jumps on the stock returns, and are latent components. For this purpose, at first we use the Variance Gamma (VG) distribution which is frequently used in modeling financial time series and leads to the revelation of the hidden market jumps' distributions. Then, our method is based on the central moments of the stock returns for estimating the parameters of the model. It is proved that the proposed method provides always a solution in terms of the jump beta coefficients. We thus achieve a semi-parametric fit to the empirical data. The methodology itself serves as a criterion to test the fit of any sets of parameters to the empirical returns. The analysis is applied to NASDAQ and Google returns during the 2006–2008 period.     

Health insurance literacy: A mixed methods study of college students

Objective: This study examines the health insurance literacy, or the ability to use health insurance effectively, of college students. Participants: A total of 455 students from a large, public university completed an online questionnaire in November 2016. Methods: A questionnaire examined students’ knowledge of commonly encountered health insurance terms and ability to apply that knowledge to determine cost-sharing in a clinical setting. Results: The majority of students were able to correctly identify the most commonly encountered terms, but could not identify terms related to plan types and options. Eighty-eight percent of students could not determine their cost-sharing for two presented scenarios. Approximately half of the students indicated they had been confused about their health insurance plan, with one-quarter of students stopping or delaying medical care due to confusion. Conclusions: Outreach and education for students should target specific deficits in knowledge such as those identified in this study.     

Risk and diversification of nonprofit revenue portfolios: Applying modern portfolio theory to nonprofit revenue management

This study uses modern portfolio theory (MPT) to estimate the risk of nonprofit revenue portfolios and examines to what degree the revenue concentration measure based on Herfindahl–Hirschman Index is associated with the portfolio risk measure based on MPT. The findings suggest that nonprofits with greater revenue concentration have lower revenue portfolio risk in the whole sample analysis. However, it is plausible that this result is dominated by organizations reliant on commercial income, which comprise over half of the sample. In fact, when examined separately, the relationship varies by an organization's primary funding structure. While higher revenue concentration is positively associated with portfolio risk for organizations relying on donations or those without a consistent primary funding source, it appears to associate with a lower portfolio risk for commercial organizations and those relying on government grants. This study reflects on the concept of diversification derived from portfolio theory and calls attention to a more nuanced approach to nonprofit revenue strategy.     

Qualitative exploration of supporting figures in the lives of emerging adults who left care compared with their noncare‐leaving peers

Studies on youth leaving care have emphasized their limited social support and their need for continuing support after emancipation. However, less is known about the nature of their existing social networks after emancipation and their roles during their transition to adulthood compared with their noncare‐leaving peers. With this in mind, 32 young adults aged 18 to 25 participated in semi‐structured interviews regarding their current support figures in order to learn whether they were congruent with their needs after emancipation. Thematic analysis revealed four main features of the two groups' social networks: (a) stability versus uncertainty as to the lasting presence of the supportive figure, (b) reliance on parents as main supportive figures versus relying on different supportive figures, (c) confidence versus uncertainty in the supportive figures' ability to help, and (d) holistic versus fragmented support of the young adults' needs. The discussion addresses the unique characteristics of care leavers in emerging adulthood and the implications of their social networks' features for their adjustment after emancipation. One of the study's recommendations is to proactively connect them to new supportive figures such as professionals or mentors by offering them mentoring programs cognizant of the instrumental and developmental tasks of emerging adulthood.     

Work-related factors associated with psychological distress among social workers

The current study assesses the association between several work-related factors and psychological distress among social workers (SWs) in Israel. The data were collected through structured questionnaires, administered to a sample of 494 SWs. The findings suggest that most of the examined work-related factors (namely, years of professional experience, personal work-related subjection to violence, burnout, compassion fatigue, and sense of coherence), with the exception of compassion satisfaction, significantly predicted psychological distress among SWs. The conclusion is that it is important to embed within the social work practice strategies for reducing sources of psychological distress (job demands) and increasing material, professional, and personal resources. Reducing the levels of psychological distress experienced by SWs will benefit not only themselves, but also their families and colleagues, as well as their clients. Moreover, this has potential benefits for the social work profession and for the general community.
