Life satisfaction and family structure among adolescents in Hong Kong

Relationships between family structure and perceived life satisfaction in overall life and five domains of the Brief Multidimensional Students’ Life Satisfaction Scale, family life, friendships, school experience, myself, and where I live were examined among 4,502 Chinese adolescent secondary school students in Hong Kong. Bivariate analyses showed that economic status was not a significant risk factor, but gender, level of study, and migrant status had to be controlled to examine the life satisfaction-family structure relations. Logistic regression analyses found that in overall life, with adolescents living with two parents as standard for comparisons, adolescents living with mother had similar life satisfaction, but those living with father only, and those with no parents, or single parent with other adults had very much higher risk of life dissatisfaction. Specifically, the risks associated with the adverse family structures were most excessive in the domain of ‘family life’.     

论国有企业的企业法主体概念之选择

国有企业概念未能表述企业法律形态,不能作为企业法主体概念.我国国有企业可表述为六类企业主体概念.即公共企业、公有公司、相对公有公司、公产合作社企业、公产参股公司、公产合作企业.这六种企业又统称公产企业,即由公有资产投资者全部或部分投资形成的、含有公有产权的、具有经营性特征的各种形式的法人或非法人经济组织.公产企业概念比国有企业概念能更准确地表达这类企业的经济性质,更好地反映现代企业制度的特征,更好地体现现代企业的内在规律,比国有企业概念更符合市场经济条件下的企业法主体概念的要求.我国应整合现行国有企业法律法规,完善以公产企业为企业法主体概念的企业立法.     

AFFECTIVE RESPONSES WITHIN A COMPLEX DECISION-MAKING TASK: THE INFLUENCE OF “PERCEPTUALLY” ILL-STRUCTURED PROBLEMS

The perceptual effects of varying levels of expert advice for potentially improving on strategic decisions were examined in conjunction with goals. The amounts of advice about decision alternatives, as well as assigned goals ranging from “nearly impossible” to “easy,” were manipulated. The task used was complex and functioned perceptually as an “ill-structured” problem. Mixed results indicated that more advice significantly affected satisfaction but advice in general had little influence on effort. On the other hand, as goal difficulty decreased, satisfaction and effort significantly increased. Easy goals were superior to more difficult ones within this perceptually ill-structured decision-making situation.

Measures of individual risk attitudes and portfolio choice: Evidence from pension participants

We use a large non-student sample to test how distinct measures of risk-attitudes relate to each other, to demographic characteristics and to real-life risk taking in the financial domain. These measures, namely the Bomb Risk Elicitation Task (BRET), self-reported willingness to take risks in general, the choice in a hypothetical lottery, the score in the Domain Specific Risk-Taking (DOSPERT) scale, appear to be positively correlated and exhibit a certain degree of consistency. Furthermore, a subset of these measures is driven by similar demographic characteristics as such that males are more risk seeking and risk-aversion increases with age. Using extensive data on the retirement portfolios of the participants during the years 2008–2014, we find that all of these measures are positively correlated with the riskiness of individual portfolios. The self-reported willingness to take risks in general appears to be the most relevant measure in predicting actual risk-taking behavior.     

Interdependency among addictive behaviours and time/risk preferences: Discrete choice model analysis of smoking, drinking, and gambling

This paper simultaneously measures the rate of time preference and the coefficient of risk aversion, as well as investigates the interdependencies of four addictive behaviours: smoking, drinking, pachinko (a popular Japanese form of pinball gambling), and horse betting among a sample of the Japanese population. We reach two main conclusions. First, there are significant interdependencies among the four addictive behaviours, in particular between smoking and drinking and between gambling on pachinko and the horses. Second, we conclude that the higher the time preference rate and the lower the risk aversion coefficient becomes, the more likely individuals smoke, drink frequently, and gamble on pachinko and the horses.     

An evaluation of product commonality and group technology production methods in a pre-defined multiple-machine scenario

Group technology has been used successfully for a number of years as a setup reduction tool. It is especially valuable in low-volume high-mix manufacturing environments where products and machines may be partitioned into product families and machine cells. The partitioning of machines or processes into cells may be limited by practical constraints, and the partitioning of products is complicated as the number of products and processes increases. In this paper, the authors examine the behaviour of various grouping strategies lauded as being appropriate in situations where machine partitioning and product routeing are determined by technological constraints. Of specific experimental concern in this paper is the effect of the mean and variance of component part commonality between products on system performance under various grouping strategies in a multiple-machine environment.
