Risk terrain modeling predicts child maltreatment

As indicated by research on the long-term effects of adverse childhood experiences (ACEs), maltreatment has far-reaching consequences for affected children. Effective prevention measures have been elusive, partly due to difficulty in identifying vulnerable children before they are harmed. This study employs Risk Terrain Modeling (RTM), an analysis of the cumulative effect of environmental factors thought to be conducive for child maltreatment, to create a highly accurate prediction model for future substantiated child maltreatment cases in the City of Fort Worth, Texas. The model is superior to commonly used hotspot predictions and more beneficial in aiding prevention efforts in a number of ways: 1) it identifies the highest risk areas for future instances of child maltreatment with improved precision and accuracy; 2) it aids the prioritization of risk-mitigating efforts by informing about the relative importance of the most significant contributing risk factors; 3) since predictions are modeled as a function of easily obtainable data, practitioners do not have to undergo the difficult process of obtaining official child maltreatment data to apply it; 4) the inclusion of a multitude of environmental risk factors creates a more robust model with higher predictive validity; and, 5) the model does not rely on a retrospective examination of past instances of child maltreatment, but adapts predictions to changing environmental conditions. The present study introduces and examines the predictive power of this new tool to aid prevention efforts seeking to improve the safety, health, and wellbeing of vulnerable children.     

Unintended pregnancy as a predictor of child maltreatment

Whereas child maltreatment research has developed considerable evidence on post-natal risk-factors, pre-natal circumstances have been largely overlooked. The circumstances surrounding a pregnancy may considerably impact the environment in which later parenting behaviors occur. This study examines one of the earliest potentially identifiable risk-factors for child maltreatment: the intentions of a pregnancy. Utilizing both mother and father reports, this study focuses on maltreatment risk, as it relates with both parents’ perspectives of the pregnancy's intention. Drawing upon data from the Fragile Families and Child Well Being study, a longitudinal, birth cohort study, survey questions were used that asked parents, at the time of the birth, whether they considered abortion for the child. Unintended pregnancy demonstrates predictive value as one of the earliest identifiable risk-factors for child maltreatment. Regardless of whether the mother or father reported the unintended pregnancy, the relationship with maltreating behavior is largely the same, although for different maltreatment types. Mothers’ reports of unintended pregnancy are associated with psychological aggression, and neglect. Fathers’ reports of unintended pregnancy are associated with physical aggression. Fathers’ perspectives regarding pregnancy intentions matter just as much as mothers,’ and accounting for their perspectives could be important in understanding the maltreating behaviors of both parents. Identifiable in the earliest stages of caregiving, unintended pregnancy may be an important risk-factor in predicting and understanding child maltreatment.

我国《防灾减灾法》的立法起草建议——我国物权法立法经验之借鉴与超越

我国《防灾减灾法》的制定应该坚持“科学立法、民主立法”这一基本要求。在指导思想上,全面贯彻落实科学发展观,从我国客观实际出发,根据《宪法》、《立法法》等相关法律的规定,按照科学立法、民主立法的基长要求,创新法规击幛起草机制,完善人大、政府法制机构、政府职能部门、专家学者或社会组织参与的多元起草模式。可以考虑由地方先行,先出台各省、自治区、直辖市的《防灾减灾综合条例》,取得经验之后,再由全国人大常委会出面牵头制定出一部全国性的统一而成熟的作为防灾减灾基本法的《防灾减灾法》。
