性别因素与脆弱儿童的长期照顾

性别因素对脆弱儿童的长期照顾的影响主要体现在以下方面:第一,在父死母嫁的情况下,女孩更容易被带入新的家庭,融入新的家庭中,成为其成员;而男孩则更容易被留在原生家庭中,形成与祖父母之间的隔代抚养关系。第二,在收养方面,女孩更容易被收养从而进入正常的家庭环境。以上这些状况的形成与亚洲地区男孩的性别偏好有非常重要的关系,这对于目前的社会福利政策与社会照顾体系提出了新的要求,需要采取一系列的措施与政策。如:通过现有的社会救助体系对祖父母—孙子女的隔代抚养关系给予支持与照顾;充分发挥社区作用,为脆弱儿童提供支持与保护;充分发挥儿童福利院的作用,为脆弱儿童提供专业支持和心理、情感指导,与家庭、社区相结合,共同为脆弱儿童的成长提供支持。     

“双积分”政策下汽车制造商竞争定价与减排策略研究

"双积分"政策的实施对汽车制造商的定价决策产生了重要影响。考虑卖方由同时生产燃油车和新能源汽车的制造商1和仅生产新能源汽车的制造商2组成,在消费者低碳偏好和价格竞争影响下分别针对制造商1对燃油车采取和不采取节能减排措施的情况,研究"双积分"政策下汽车制造商的定价策略和减排决策,探讨新能源汽车积分值和积分比例要求对政府和企业决策的作用效果。进一步,通过对不同情形的结果进行分析,得到"双积分"政策的出台、消费者低碳偏好及制造商采取节能减排措施对制造商定价和减排决策带来的变化,并通过算例分析验证了结论。研究结果表明:(1)"双积分"政策可以降低新能源汽车的价格,提高新能源汽车制造商的利润,促进燃油车主动减排。(2)当新能源汽车的需求价格弹性系数和需求交叉价格弹性系数处于较高水平时,政府要制定较高的每台新能源汽车积分值。(3)燃油车的油耗水平存在一个环境属性标准,当油耗水平低于一定值时,随着新能源汽车积分比例要求的不断增大,制造商1选择提高燃油车价格。(4)消费者低碳偏好是提高燃油车减排水平的重要因素,政府可以对减排技术先进的燃油车制造商进行低油耗认证,提高消费者低油耗燃油车需求,激励燃油车制...     

An Evaluation of Stimulus Preference Assessment Methodology in Organizational Behavior Management

The organizational behavior management literature has yielded few stimulus preference assessment methodologies for use with employees. The current investigation compared three preference assessments (ranking, survey, and multiple stimulus without replacement procedures) found in the organizational behavior management literature for their ability to predict reinforcers for direct care staff members’ behavior. In the first experiment all assessments were effective for predicting reinforcers, but the results were limited by a lack of control items in the assessment. In the second experiment the survey and ranking assessments both proved to be effective for identifying reinforcers and neutral or ineffective stimuli. Implications of these results and directions for future research are discussed.     

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.     

Texting among United States young adults: An exploratory study on texting and its use within families

The current study examines general text messaging tendencies, patterns of and reasons for texting family members, and the impact of texting on familial relationships among a young U.S. adult sample. Participants were recruited through Facebook; they then completed an online questionnaire. Data from 127 young adults (men: 38; women: 87; unidentified: 2) are analyzed and compared by gender. Findings suggest that young adults text at high rates per month. Participants generally report a prompt response to texts and their ability to honestly express feelings within these messages. Results also suggest participants text family members for a variety of reasons, such as to convey information, plan activities, and engage in general conversation. Distinct gender differences, however, are evident regarding who men and women text as well as texting's effects on familial relationships. Overall, these findings expand researchers’ understanding of texting in general and its impact within the family.

A Feminist Policy Analysis Framework

ABSTRACT

Most policy analysis models, both inside and outside of social work, approach policy in a gender-neutral manner. This fact belies the many ways our society is organized around gender, which is often regulated through policy. This article outlines a model for looking at policies through a gendered lens by framing a set of questions to be asked in a feminist policy analysis. The complexities and underlying issues inherent in such a model are discussed, as well as the model's implicit goals and values. The model provides an important framework for policy analysts and teaching students about policy.     

△-correct decision for location and scale parameters

In selecting t out of k populations, a △-correct decision is said to be made if the smallest location parameter for the selected populations is not more than △ below the largest location parameter for the non-selected populations. (For seal? parameters there is a similar definition in terms of ratio3.) The minimum probability of △-correct decision over the entire parameter pace is shown to be equal to the minimum probability of correct selection over a preference zone determined by △.     

我国非营利组织税收优惠法律制度完善的研究

我国为鼓励非营利组织的发展,为捐赠人和非营利组织自身都制定了一系列税收优惠措施。但是现阶段的税收优惠制度存在的诸多不足不能满足我国非营利组织的发展要求。我国应从合理区分非营利组织性质,对非营利组织的营利收入予以合理免税、改进捐赠激励机制等方面完善非营利组织的税收优惠法律制度,以便实现非营利组织的可持续发展。
