印度的环境非政府组织：以NBA为例

环境运动在印度有着较长的发展历史。1988年,NBA宣布成立,标志纳尔默达河谷的人民运动从零散抗议走向了系统整合。它的发展经历了三个主要阶段:激进的甘地式抗议阶段;合法的群众斗争阶段;曲折而严峻的斗争阶段。NBA之所以能够组织和长期维持高水平的公众参与,与其广泛的运动联盟战略有密切的关系。     

Presidential Election Cycles and the Turn‐of‐the‐Month Effect*

Objective. In this research, the presidential election cycle hypothesis is evaluated within the context of the turn‐of‐the‐month effect found in stock returns. Methods. Returns from the daily Standard & Poor's 500 (S&P 500) index, the Dow Jones Industrial Average (DJIA) index, and the NASDAQ Composite index are grouped into turn‐of‐the month returns and non‐turn‐of‐the‐month returns. Statistical comparisons are conducted to evaluate the returns based on administration subperiod, temporal subperiod, and party affiliation. Results. The results provide evidence of higher turn‐of‐the‐month returns in the second half of presidential terms. The higher turn‐of‐the‐month returns account for most of the additional returns found in the second half of presidential terms evidenced in prior research. Conclusions. The persistent higher investment returns for stocks found in the second half of presidential terms can be linked to fiscal and administrative policies that increase household liquidity prior to elections. Incumbents attempt to influence voter choice and energize core constituencies by increasing household liquidity prior to elections through fiscal and administrative policies. These actions create higher turn‐of the‐month returns in the second half of presidential terms, which generate additional overall investment returns for the period.     

Stability and change – a 7‐ to 8‐year follow‐up study of mental health problems in Norwegian children in long‐term out‐of‐home care

The aim of the study was to explore stability and change in mental health problems in Norwegian children aged 6–12 years old (n = 70) in long‐term out‐of‐home care. The children's mental health problems were assessed shortly after the placement and 7–8 years later by the caregivers and the teachers on the Revised Rutter Scales. Information on pre‐placement and placement factors were collected from the child welfare workers. At a group level the children's mental health problems had improved significantly over time according to the teachers' reports. According to the caregivers' reports, however, the children's problems were high and stable across time. Analyses aimed at detecting individual changes revealed a great variability in development according to both informants, indicating that treating the placed children as a homogenous group could be misleading. Several pre‐placement and placement variables were associated with the change in the children's mental health problems from the time of placement to the follow‐up time according to both informants' reports. However, all the predictors were accounted for by the strong effect of the children's problem scores when entering care.     

Towards a second‐order view of child protection placement‐related decision‐making

Child protection workers are tasked with prioritizing and facilitating safe, secure and preferably, long‐term care arrangements for children and adolescents living within the child protection system. Recognizing the complexities associated with this task, this paper will propose that the application of theory – namely attachment theory and family systems theory – may aid in the conceptualization of placement decision‐making within the context of child protection practice. In particular, this paper will describe a framework entitled: Towards a second‐order view of child protection placement‐related decision‐making. This framework assumes the position that the ideals of relationship security and permanency of placement are more accessible in instances in which practitioners are able to locate themselves within temporary, stabilized but ultimately evolving systems. Specifically, the practitioner is encouraged to conceptualize where their individual selves, the broader child protection system and family system are located at any one point in time, whilst also identifying the direction in which these systems should be moving.     

Wal‐Mart and County‐Wide Poverty*

Objectives. This study seeks to identify the independent effect of Wal‐Mart stores on changes in U.S. family‐poverty rates at the county level. We draw on the contributions of a number of disciplines to enhance our understanding of the broader forces that influence poverty. Methods. A key innovation is that we estimate a two‐stage regression model, in which an instrument is created for new Wal‐Mart stores from a location equation; this reduces any potential endogeneity bias in the poverty‐change equation. In addition, we use spatial econometric methods to correct for spatial dependence bias. Results. After controlling for other factors determining changes in the poverty rate over time, we find that counties with more initial (1987) Wal‐Mart stores and counties with more additions of stores between 1987 and 1998 experienced greater increases (or smaller decreases) in family‐poverty rates during the 1990s economic boom period. Conclusions. Wal‐Mart creates both benefits and costs to communities in which the chain locates. These benefits and costs need to be weighed carefully by community decisionmakers in deciding whether to provide public subsidies to the chain.     

Re‐thinking Indigenous over‐representation in prison

It is now nearly two decades since the Royal Commission into Aboriginal Deaths in Custody recommended that a determined effort be made by all Australian Governments to reduce the level of Indigenous over‐representation in prison. The disparity between Indigenous and non‐Indigenous imprisonment rates, however, is now wider than it has ever been. This article reviews research published over the last twenty years which calls into question both the Royal Commission's analysis of the causes of Indigenous over‐representation in prison and subsequent policies adopted to reduce it. It concludes by arguing that future efforts to reduce Indigenous over‐representation in prison should be directed at dealing with the underlying causes of Indigenous involvement in crime, especially drug and alcohol use, child neglect and abuse, poor school performance and unemployment.     

Thirteen‐ and 18‐month‐old Infants Recognize When They Need Referential Information

To learn from conspecifics, infants would be greatly advantaged by knowing when to seek information from them. Although in prior work infants used a labeler's gaze direction to infer the referent of a novel label, it was unclear whether infants in these studies recognized that they needed information or were happening upon the information by simply orienting to the labeler's voice. To address this issue, we presented 13‐ and 18‐month‐olds with either one or two novel objects and provided a novel label. If infants seek referential information, they should look more to the labeler in the presence of two objects relative to one object, because the labeler's intended referent is highly ambiguous in the two‐object case. This prediction was confirmed in two studies. In contrast, infants' looking was equivalent in the presence of one vs. two objects in a baseline phase, when no labels were provided. Thus, 13‐ and 18‐month‐olds actively seek clarifying gaze information to resolve ambiguous learning situations. Word learning appears to be a rich pragmatic process as early as the end of the first year of life.     

Two‐generation preschool programme: immediate and 7‐year‐old outcomes for low‐income children and their parents

Preschool children living in low‐income families are at increased risk for poor outcomes; early intervention programmes mitigate these risks. While there is considerable evidence of the effectiveness of centre‐based programmes in other jurisdictions, there is limited research about Canadian programmes, specifically programmes that include children and parents. The purpose of this study was to evaluate a single‐site, two‐generation preschool demonstration programme for low‐income families in Canada. A single group, pre‐test (programme intake) /post‐test (programme exit) design with a 7‐year‐old follow‐up was used. Between intake and exit, significant improvements in receptive language and global development were found among the children, and significant improvements in self‐esteem, use of community resources, parenting stress and risk for child maltreatment were found among the parents. These positive improvements were sustained until the children were 7 years old. Public investment in two‐generation preschool programmes may mitigate risks for suboptimal child development and improve parental psychosocial outcomes.
