Is giving or receiving psychologically beneficial to older mothers in South Korea? Importance of marital status

In order to understand intergenerational financial transfers and subjective well-being for older mothers, this study argues that marital status is an important factor to be considered. Using the first wave of the Korean Longitudinal Study of Aging (KLoSA), this study finds that married older mothers report higher levels of life satisfaction when they provide economic support but widowed older mothers feel higher levels of life satisfaction when they receive economic support. Also, regular or irregular financial support appears to also matter in the associations between financial support and life satisfaction. These findings suggest that married and widowed older mothers have different viewpoints about the parent-children relationship.     

Internet risks and expert views: a case study of the insider perspectives of youth workers in Hong Kong

This study collects and analyses the viewpoints of front-line youth workers regarding the notion of ‘Internet risks’. Previous studies have examined and discussed various dangers of the Internet. Parental, school, and governmental interventions are often called for by those concerned. The implicit assumption is that these are the people who possess the expertise to tackle the problems at hand. Through participation in three forums focusing on ‘Internet risks’, and in-depth interviews with 10 such ‘experts’ in Hong Kong, the study examines if this is a valid assumption. It finds that experts perceive Internet risks rather differently. In addition to the more conventional views about content, contact and conduct risks, our interviewees are aware that a new order is quickly emerging in the new media environment. Despite being considered as ‘experts’, they do not necessarily know how to tackle the so-called ‘youth-at-risk’. Rather, they are exploring how they would capitalize on the opportunities offered by the developments. The key findings highlight the need to critically review the notion of ‘Internet risks’. As with other risk frameworks, the ultimate aim is to develop intervention programmes. In this regard, risks are often treated as concrete problems that can be solved. Youth experts, however, find that the changing scope, speed and persistence of communication in today's information society present the biggest challenge in youth work. The existing framework of risks was unable to describe and account for such risks. In response, Internet risk has to be reconceptualized so that more updated, relevant and imaginative intervention can be introduced.     

我国企业海外撤资的实物期权分析

由于世界经济形势变化、地区政局不稳和企业对国际市场的误判,我国部分对外投资企业亏损严重,面临着从海外撤资的决择。利用实物期权法分析企业退出问题,参照贝尔曼方程,构建撤资决策的实物期权模型,分析对外投资企业撤资决策的价值。算例分析表明,对外投资企业选择的贴现率、利润的波动率和撤资成本的变化均能影响撤资的时机和方式。我国对外投资企业应根据形势变化和自身实力,不断加强自身抵抗风险的能力,灵活选择趁机抢占国外市场的进攻策略,或尽早撤出以获得放弃期权价值的防守策略。     

Subjective well‐being in the new China: religion,social capital,and social status

We present the first nationally representative evidence on the relationship between religion and subjective well‐being for the case of China. Research on Western societies tends to find a positive association between being religious and level of well‐being. China provides an interesting critical case as the religious population is growing rapidly and the religious and socioeconomic environments are profoundly different from Western societies, implying different mechanisms might be at work. We hypothesize to find a positive association between religion and well‐being in China too, but argue social capital, for which strong evidence is often found in Western societies, is unlikely to be an important mechanism because religion in China is generally non‐congregational. Instead, we argue that the private and subjective dimension of religion matters for well‐being in China by helping adherents have an improved sense of social status relative to the non‐religious in the context of rapid social change and growing inequality. Our results generally support these predictions.     

制度变迁过程的历史沉淀成本效应分析

在新古典完全竞争市场理论——历史沉淀成本决策无关性的假设前提背景下,从未来不确定性、信息不完全和财务预算约束等角度考察历史沉淀成本对制度变迁过程的影响,为制度变迁过程确立一个新的分析视角,从而弥补了原有研究的不足。在现实经济生活中,市场不完全是常态,有限理性、交易成本、信息不完全和环境不确定性等因素普遍存在,历史沉淀成本很容易发挥作用,从而表明:未来越不确定,信息越不完全,资源越稀缺,导致财务预算越硬,历史沉淀成本效应越大,制度变迁过程越困难;反之越容易。由此可发现,在放松完全竞争市场的假设前提条件下,当事人的决策不可能不受到历史沉淀成本的影响。因此,只有当事人对历史沉淀成本的约束条件作出正确的理性反应,才能使其决策更加贴近真实世界,这对于全面认识制度变迁过程具有重要的理论创新意义和现实指导价值。     

我国财政赤字和货币供应量联动性的实证模型分析

近期以来国际金融危机的加深,进一步揭示了一国财政赤字与宏观经济之间的深刻关联。进入新世纪以来,我国运用财政赤字的手段和方法不断改进,对于我们应对国际金融市场的动荡、促进内需和经济增长起到了很大作用。但同时,财政赤字与货币发行量之间不可调和的正向关系,也给我国经济体系带来了一定的隐患。因此,通过理论梳理与实证分析来理清赤字规模和货币供应量之间的关系,有助于我们今后宏观经济管理手段和金融市场监管能力的提升。     

胡风研究:历史的还原与问题的凸显——对商金林、吴永平、解志熙诸先生胡风研究的考量

在新世纪,商金林、吴永平、解志熙等人在胡风研究方面做出了很大的成绩,得到了学界的关注.商金林对胡风1927年到1928年胡风编辑《武汉评论》和《策进》史料进行了详细论证,为学界贡献了新的材料,但其认为现代作家日记、书信中的胡风的负面形象更真实,这个观点似有商榷之处;吴永平在《隔膜与猜忌——胡风与姚雪垠的世纪纷争》中挖掘了大量史料,但其关于胡风文艺思想是“党的文学”的观点并不全然合理,且论述过程也有诸多不尽人意之处;解志熙认为胡风主张启蒙优先甚至启蒙优胜论的观点也与事实有一定的出入.总之,上述诸人在为胡风研究做出重要贡献的同时,也存在着诸般可供商榷的地方.     

在自然的怀抱中塑造自己的人格——徐志摩与雪莱诗歌自然意象比较

诗人对自然有着与生俱来的虔诚与顶礼膜拜,徐志摩在自然中显得逍遥而拘谨,体现出一种乐观式的悲观情思,而雪莱在自然中显得沉静而放达,渗透着一种悲观式的乐观情怀。他们通过诗歌在一种独特的体验下建立属于他们各自的自然意象群落,并且都带上了强烈的主体意识色彩,其艺术表现方式由此也各具特色。     

Efficacy of Risk-Based, Culturally Sensitive Ogaa (Walleye) Consumption Advice for Anishinaabe Tribal Members in the Great Lakes Region

The Great Lakes Indian Fish and Wildlife Commission (GLIFWC) has produced Ogaa (walleye— Sander vitreus ) consumption advisories since 1996 for Anishinaabe from GLIFWC member tribes in the 1837 and 1842 ceded territories of Wisconsin. GLIFWC's advisory maps were revised in 2005 to address cultural sensitivities (to protect tribal lifeways), to utilize recent mercury exposure information, and to incorporate changes in advisory levels for methyl mercury. Lake-specific, risk-based, culturally sensitive consumption advice was provided on color-coded maps for two groups: children under age 15 years and females of childbearing age, and males 15 years and older and females beyond childbearing age. The maps were distributed to, and a behavioral intervention program developed for, the six GLIFWC member tribes in Wisconsin as well as member tribes in Minnesota and the 1842 ceded territory of Michigan. Tribal fish harvesters, tribal health care providers, women of childbearing age or with young children, tribal leaders, elders, and children were targeted specifically for the behavioral intervention. The efficacy of the behavioral intervention was assessed using surveys of 275 tribal fish harvesters from Wisconsin, 139 tribal harvesters from Michigan and Minnesota, and 156 Wisconsin women of childbearing age. Significant increases in the percentage of survey participants who indicated awareness of advisory maps occurred among Wisconsin harvesters (increase from 60% to 77%), Michigan and Minnesota harvesters (29% to 51%), and women of childbearing age in Wisconsin (40% to 87%). A significant increase in preference for smaller Ogaa occurred among tribal harvesters in Wisconsin (41% to 72%) and tribal harvesters in Michigan and Minnesota (49% to 71%), although not among women of childbearing age. The GLIFWC map-based advisory program did not adversely affect tribal harvest of Ogaa, which increased from 63,000 to 88,000 fish in the three states after the intervention.
