新时期汉语贬义词语褒义化现象研究

新时期,由于部分汉语贬义词语增加了积极的理性意义,这使得附着其上的感情色彩义也随之褒义化。贬义词语褒义化的程度体现出明显的层次性：有偶一为之的,有相对固定使用的,也有已完成了贬义词语褒义化过程的。这些词语转化的动态过程包括其感情色彩的历时演变过程和在人群中的共时扩散过程,其转化机制在于褒义义素的显化,产生这种现象的原因是与当下人们观念的变化、娱乐时代语言符号的意义不在场、使用该类语言形式的人群的特殊心理以及他源性文化的影响密不可分。汉语贬义词语褒义化过程中体现的层次性也决定了规范该类词语时的层次性。     

基于棉农角度的棉花期货最优套期保值比率估计

对棉农而言,国内现有关于棉花期货最优套保比率的研究存在明显不足。文章分别用OLS与ECM方法估计了不同套保期限下棉花期货最优套保比率,结果显示两种方法得到的最优套保比率和套保效果相差极小,而不同套保期限的套保效果却显著不同：套保期限越长,最优套保比率就越大,套保效果也越好。故对棉农而言,在棉花种植时即进行套期保值能更好地对冲风险;此外,随着棉花期货市场的发展,套保的有效性会不断增强,棉农运用期货能更好地规避价格风险。     

Introducing social insurance for long‐term care in Taiwan: Key issues

Nadash P, Shih Y.‐C. Introducing social insurance for long‐term care in Taiwan: Key issues Taiwan will shortly complete its comprehensive social safety net, which includes national health insurance, retirement security, and unemployment insurance, by introducing long‐term care (LTC) insurance – putting it ahead of the many countries that rely on a patchwork of policies to address the need for LTC. The program, to be implemented in 3 to 5 years, will cover all citizens on a primarily social insurance basis. The range of LTC policy options considered is discussed, particularly how to structure the program, how to finance and regulate it, and how to develop its inadequate LTC infrastructure and workforce. Particularly thorny issues include the choice of social insurance, the feasibility of cash benefits, and how to address Taiwan's heavy reliance on foreign workers. Taiwan's increasingly democratic character, along with high levels of public support for the program, creates significant pressure on politicians to deliver on their promises to implement LTC reform. Key Practitioner Message: ?Emphasizes the importance of policy learning from other environments; ?Highlights the need for a strong regulatory and provider infrastructure for delivering long‐term care services; ?Emphasizes the need for training, support, and appropriate regulation of the long‐term care workforce.     

Long-term changes in parenting and child behavior after the Home-Start family support program

Background

The intervention Home-Start is a wide spread program in a number of countries, among which the Netherlands. In Home-Start, trained volunteers visit families with young children in need of support once or twice a week to help them to deal with problems in family life and parenting. Little is known, however, about the effects of Home-Start. This study describes short-term and long term changes in families that participated in Home-Start.

Methods

Three groups of families with young children (at the start mean age 1 1/2 years) were followed over a period of four years. One of the groups of families participated in the Home-Start family support program in the first 6.6 months of this period. The two other groups were (1) a randomly selected community sample and (2) a group of families with elevated parenting stress and a need for support. Data were collected at the beginning of the study, (after median 1.4 months), directly after the intervention (median 6.6 months) and at two follow-up occasions (respectively, median 12.5 and 49.2 months after the first measurement). At the last measurement, data were available for 33, 45 and 34 families respectively.

Results

Multilevel analysis showed more positive changes in parental wellbeing, competence and behavior (more consistent behavior and less rejection) during the intervention period in the Home-Start group than in the two other groups. At the three year follow up, the Home-Start group showed, compared to the other groups, more improvements in parenting (more responsiveness), but also diminished child externalizing and internalizing behavior problems (less oppositional defiant behavior, affective problems and anxiety problems).

Conclusions

Home-Start seems a promising family support intervention that deserves to be studied more extensively.

论农村内源性增收机制的构建

农民增收是工业化中后期一个非常棘手而现实的问题,解决这一问题的关键要依靠挖掘和开发农村内源性增收渠道,构建内源性增收机制,通过资源整合、专业化与分工、规模调整、结构优化等农民能够自我掌控的方式完成。同时,要充分发挥外源性增收机制的牵引和拉伸作用,通过“内推外拉”,共同构建农民增收的长效机制。
