政府动态奖惩机制下绿色建筑供给侧演化博弈研究

从绿色建筑供给侧角度出发，构建消费者效用函数、开发商利润函数和政府与开发商的演化博弈模型，分析消费者绿色偏好、建筑绿色度、成本等因素对建筑价格、需求和利润的影响以及政府动态奖惩政策下系统的演化稳定策略。结果表明：消费者绿色偏好支付系数和建筑绿色度的增大有利于绿色建筑价格、需求和利润的提高，但高成本却使需求和利润降低；政府采用静态补贴与静态税收政策时，博弈系统不存在演化稳定策略，采用动态补贴与静态税收、静态补贴与动态税收、动态补贴与动态税收三种政策组合时，系统存在演化稳定策略；动态补贴与静态税收的政策组合在推动绿色建筑发展方面优于其他政策；开发商开发绿色建筑的概率与补贴上限值呈负相关，与税收上限值呈正相关。     

Age limits for participation in child protection court proceedings in Sweden

According to the UN Convention on the Rights of the Child and Swedish legislation, children have the right to participate in child protection proceedings. The aim of this paper is to describe and analyse the notion of age and maturity in child protection proceedings in order to elucidate how these aspects could influence children's rights to participate. We focus on the view of three groups of actors involved in child protection proceedings in Sweden—social workers, lawyers, and laypersons in social welfare boards and administrative courts—and on how children's age and maturity should be taken into consideration in decisions on their participation in court. The analysis is based on survey data. The study found that social workers, laypersons, and lawyers have different views on when children are old enough to have the right to litigate in court. Additionally, there is no consensus on how the maturity of the child can be assessed to inform the decision about participation. More discussion is needed about what competences a child needs to participate in court and to what extent this right should be limited by their age. Importantly, courts and decision‐making proceedings can be made more child friendly.     

Statistical Distributions of Daily Breathing Rates for Narrow Age Groups of Infants and Children

Children may be more susceptible to toxicity from some environmental chemicals than adults. This susceptibility may occur during narrow age periods (windows), which can last from days to years depending on the toxicant. Breathing rates specific to narrow age periods are useful to assess inhalation dose during suspected windows of susceptibility. Because existing breathing rates used in risk assessment are typically for broad age ranges or are based on data not representative of the population, we derived daily breathing rates for narrow age ranges of children designed to be more representative of the current U.S. children's population. These rates were derived using the metabolic conversion method of Layton (1993) and energy intake data adjusted to represent the U.S. population from a relatively recent dietary survey (CSFII 1994–1996, 1998). We calculated conversion factors more specific to children than those previously used. Both nonnormalized (L/day) and normalized (L/kg-day) breathing rates were derived and found comparable to rates derived using energy estimates that are accurate for the individuals sampled but not representative of the population. Estimates of breathing rate variability within a population can be used with stochastic techniques to characterize the range of risk in the population from inhalation exposures. For each age and age-gender group, we present the mean, standard error of the mean, percentiles (50th, 90th, and 95th), geometric mean, standard deviation, 95th percentile, and best-fit parametric models of the breathing rate distributions. The standard errors characterize uncertainty in the parameter estimate, while the percentiles describe the combined interindividual and intra-individual variability of the sampled population. These breathing rates can be used for risk assessment of subchronic and chronic inhalation exposures of narrow age groups of children.     

影响消费者购买决策的产品属性效用实证分析

本文采用UTASTAR方法,以手机产品为例,从多属性效用这个新视角来评估决策这一因素,研究了七种手机产品对消费者的总效用、各属性的边际效用及各影响因素的重要程度.目前,产品属性影响力大小的获知主要依靠市场调研或网络调研,该文所采用的UTASTAR方法是市场调研方法的补充和完善.论文首先阐述了UTASTAR方法在研究消费者购买决策方面的优势,然后对通过网络挖掘获取的手机属性数据进行定量计算,结果各款手机的总效用排序与实际调查得到的消费者的关注度基本一致.另外,本文计算得到的属性边际效用和属性的权重,能够使营销人员和产品设计人员更好地把握手机产品的重要属性及其重要程度,有利于指导企业制定具有竞争力的产品和市场战略.     

评鲍德里亚的"消费社会理论"

鲍德里亚系统提出了"消费社会"的理论。他企图对唯物史观进行"颠覆"是错误的。但是不能简单地认为他是资本主义制度的辩护士。鲍德里亚不懂得马克思从根本上颠覆了国民经济学和唯心主义历史观的两种"幻象",从而奠定了生产和劳动对于人类社会存在与发展的基础性地位;不懂得消费与生产的现实辩证关系,片面地离开生产探讨消费的新特征,甚至主张用消费取代生产。消费异化是劳动异化的表现。技术救赎不可能解决当代人类面临的重大社会问题。     

宋明理学与中华民族精神

宋明理学是中国古代社会后期别具特色和风格的哲学思维形态。它被统治阶级奉为官方哲学,长达六七百年之久,支配着我国经济、政治以及文化思想的发展。由于它构建了一套严谨的极具思辨性的理论体系,把先前儒家所提出的伦理纲常上升到宇宙本体论的高度,从而强化了爱国主义,反映了时代的共同价值取向,提升了中华民族对于崇高精神境界的追求,正是这些承担并体现了形成与发展中的中华民族精神,是锤炼和塑造当代中华民族精神的文化土壤。     

对第二语言习得中“年龄小优势论”的辩证分析

多数人认为:在第二语言习得过程中,年龄小的人比年龄大的人学得好;儿童比成年人学得好。通过对大量的有关年龄因素如何影响"第二语言习得"(SLA)的资料的辩证分析,肯定了在自然条件下,就语音和语法方面而言,年龄越小,学得越好,但年龄大的人在读写方面的优势以及成年人比儿童能够更快地习得第二语言语法的事实证明了:在"第二语言习得"中,年龄小的人并非总是比年龄大的人学得好,从而论证了"年龄小优势论"具有一定的片面性。     

袁宏道文学思想再认识

明中叶以后 ,以公安三袁为主力的公安派高举“性灵”大旗 ,开创了与“复古”论调大相径庭的一代风气 ,影响甚大。而公安三袁中尤以袁宏道为重 ,袁宏道的文学思想表现在三个方面 :一、识时通变的文学发展观 ;二、“独抒性灵”的创作主张 ;三、“本色轻淡”的艺术趣味。
