从事实到规范:物权法民意基础的实证研究——以土地问题为中心

以社会调查数据为判断标准,物权法对土地制度发展的事实,既有呼应,也有背离、漠视、逃避和模糊。呼应主要包括:明确坚持保护私有财产;妥善规定承包经营权的流转、登记的效力、土地使用权到期后的处理等。背离表现为:继续强调集体土地所有权。漠视表现为:未规定建设用地使用权的类型和取得时效;未明确承认宅基地使用权、集体建设用地使用权的流转等。逃避表现为:未能明确统一登记的具体机构及其设置等。模糊表现为:未能清楚界定征收条件、征收中物权的变动时间、登记审查等。

Autonomy,Belongingness, and Engagement in School as Contributors to Adolescent Psychological Well-Being

Self-determination theory emphasizes the importance of school-based autonomy and belongingness to academic achievement and psychological adjustment, and the theory posits a model in which engagement in school mediates the influence of autonomy and belongingness on these outcomes. To date, this model has only been evaluated on academic outcomes. Utilizing short-term longitudinal data (5-month timeframe) from a set of secondary schools in the rural Midwest (N = 283, M age = 15.3, 51.9% male, 86.2% White), we extend the model to include a measure of positive adjustment (i.e., hope). We also find a direct link between peer-related belongingness (i.e., peer support) and positive adjustment that is not mediated by engagement in school. A reciprocal relationship between academic autonomy, teacher-related belongingness (i.e., teacher support) and engagement in learning is supported, but this reciprocal relationship does not extend to peer-related belongingness. The implications of these findings for secondary schools are discussed.

Does fertiliser use improve household welfare? Evidence from Ghana’s cocoa industry

This article analyses welfare impacts of fertiliser adoption using data collected from 838 cocoa farm households in the four key cocoa-producing regions in Ghana. Using propensity score matching (PSM), the study indicates that application of fertiliser leads to significant gains in farm yields, farm income, consumption expenditure, consumption expenditure per capita, and value of productive farm assets. The article concludes that cocoa-specific programmes such as Cocoa High Technology (Cocoa Hi-tech), initiated to intensify the application of improved farm technologies such as fertiliser, should be strengthened through effective and efficient management systems.     

两种“概念”,还是两种“自由”——解读伯林的Two Concepts of Liberty

伯林首先是一个思想史家。解读他在《两种自由概念》中所使用的消极自由和积极自由,主要是用以概括和考察以往政治思想史两种不同类型的思想家们对自由的理解,而不是为了直接阐发他本人对自由的理解。消极自由和积极自由这两个字眼,在伯林这里分别代表的是对自由做不同理解的两个概念,而不是说有两种自由,或自由有两种。对于伯林来说,消极自由和积极自由是一种自由的两个方面。     

Youth Development Outcomes of the Camp Experience: Evidence for Multidimensional Growth

Three thousand, three hundred and ninety-five families, whose child attended one of 80 different day or resident summer camps for at least one week, completed customized questionnaires that measured growth from precamp to postcamp in four domains: Positive Identity, Social Skills, Physical & Thinking Skills, and Positive Values & Spirituality. Parents, children, and camp staff reported significant positive change in these four domains; more than would be expected by maturation alone. Most gains were maintained or showed additional growth six months later. Few of the camp's structural elements correlated with growth, nor did striking gender, age, or ethnicity differences emerge. The study highlights the particular strengths of camp as an educational institution and social movement and suggests that different variations of summer camp can provide potent developmental experiences.

First-Year College Student Affect and Alcohol Use: Paradoxical Within- and Between-Person Associations

Based on 10 weekly telephone interviews with first-year college students (N=202; 63% women; M=18.8 years, SD=.4), within- and between-person associations of positive and negative affect with alcohol use were examined. Multi-level models confirmed hypothesized within-person associations between weekly positive affect and alcohol use: Higher positive affect weeks had greater alcohol consumption, more drinking and heavy drinking days in the same week, and less plans to drink the following week. However, between-person, average positive affect did not predict individual differences in alcohol use. The negative affect—alcohol use association was complex: Within-person, higher negative affect was associated with less drinking days but between-person, with more drinking days; lability in negative affect was associated with greater average alcohol use and more drinking and heavy drinking days. Health promotion efforts for late adolescent and emerging adult students are advised to recognize these paradoxical effects (e.g., promoting dry celebratory campus-events, strategies to manage negative mood swings).

论由主权者产生的法律

文章从对哈特法概念的分析推导出＂实证法＂与社会可能具有的紧张关系,并按波斯纳的观点,把实证法的构成者：制定法、先例,以及自然法观念,都仅仅看成是法官分析案件的信息,提出了法律就是在一定的社会秩序中由立法机关（包括制宪机关）和司法机关产生的规范产品,并突出由主权者（人民）形成的社会背景结构。
