Malthus to modernity: wealth,status, and fertility in England, 1500–1879

A key challenge to theories of long-run economic growth has been linking the onset of modern growth with the move to modern fertility limitation. A notable puzzle for these theories is that modern growth in England began around 1780, 100 years before there was seemingly any movement to limit fertility. Here we show that the aggregate data on fertility in England before 1880 conceals significant declines in the fertility of the middle and upper classes earlier. These declines coincide with the Industrial Revolution and are of the character predicted by some recent theories of long-run growth.     

The impact of mental health issues, substance use, and exposure to victimization on pregnancy rates among a sample of youth with past-year foster care placement

The purpose of this study is to (1) compare youth entering substance abuse treatment with and without a history of foster care placement to determine any differences in mental health, substance use, and exposure to victimization, and (2) determine if mental health, substance use, and/or exposure to victimization predict past pregnancy among the sample with a history of foster care placement. The pooled dataset consisted of 17,124 adolescents (12-17 years of age) who completed the Global Appraisal of Individual Needs at intake for substance abuse treatment in 2009. Of these, 366 (2.1%) reported having been in foster care in the past year. When compared with a non-foster care sample, the foster care sample reported significantly higher internal mental distress scores, behavior complexity scores, and general victimization scores, after controlling for race, gender, and level of care. Problems associated with substance use did not differ between groups, though regular tobacco use was present at a higher rate in the foster care sample. Multivariate logistic regression results revealed that, within the foster care sample, internal mental distress and gender predicted past pregnancy. There may be room for intervention within substance abuse treatment centers for youth with a history of foster care, who may be at risk for pregnancy if their levels of internal mental distress are high.     

The role of law enforcement in schools: the Virginia experience--a practitioner report

Although there has been little academic research on the impact of placing police officers in schools, this practice has grown substantially in response to school shootings and other violent crimes in schools. With a standardized training program since 1999, the state of Virginia has law enforcement officers working in approximately 88 percent of Virginia's 631 secondary schools. Based on this experience, the state training coordinator describes how police officers should be selected and prepared to work as school resource officers. The success of school-based law enforcement requires careful selection and specialized training of officers who can adapt to the school culture and work collaboratively with school authorities.     

“社区”的现实意义与循证政策依据分析

Bryson和Mowbray曾在1981年写文章批判政府盲目使用“社区”一词,并谈到关系着社区的循证政策如何在2005年成为一句空洞的政治口号。两篇文章都刊登在澳大利亚的社会问题期刊上。本文通过定性分析的方法搜集数据,考察南澳大利亚州某地方政府对“社区”的主观和现实意义作何理解,以评估其与社会政策制定者所使用的“社区”一词的吻合度。笔者认为,在2009年,社会政策制定者所使用的“社区”与围绕此主题展开的大量研究或者当前个体与家庭的情况缺乏共鸣,从而导致针对社区的社会政策其初衰与效果不相匹配。     

The knowledge of caring: revisiting the need for knowledge support of carers

Foster carers' knowledge of caring for abused and neglected children is a largely under-researched area. We know very little about the nature of carers' knowledge in relation to caring for children who have been abused or neglected. This paper reports on an exploratory study which examined the knowledge of caring. Qualitative data were analysed based on in-depth interviews with 10 foster carers in Queensland, Australia. A range of knowledge was identified showing an interaction of both personalized and formal understandings in the caring response. Given the breadth of knowledge recognized from the analysis, this paper presents one dimension of their knowing: theory and abuse-indicated understandings. Participants' responses in these areas were at times sound, but many struggled to provide convincing and well-formed explanations of topics, such as attachment, harm and child development which may suggest that their understandings are not what they could be. Although further research is needed on a larger scale, this study does highlight the necessity to re-examine processes and strategies for carer knowledge support, so as to strengthen their understanding of these issues.     

Child Marriage in Canada

Child marriage, defined as formal or informal marriage before the age of 18, is a globally recognized indicator of gender inequality. Canada has placed itself at the forefront of global efforts to end child marriage as part of its commitment to the United Nations Sustainable Development Goals. Despite these global aspirations, child marriage remains legal throughout Canada. Data from vital statistics agencies and recent censuses indicate that child marriage, although rare, is practiced across the country. In 2016, nearly 2,300 children between 15 and 17 years of age were in union, a prevalence of 0.2 percent. The vast majority (98 percent) of these were informal, common‐law unions. Demographic patterns of child marriage in Canada are similar to those observed in many low‐ and middle‐income countries. Girls were far more likely to be married as children than boys and typically wed much older spouses. There were marked differences in the prevalence of child marriage across the country, with the highest estimates found in Alberta, Manitoba, Saskatchewan, and the territories. These findings draw attention to the discrepancy between Canada's domestic law and its foreign policy. They also highlight thorny challenges inherent in efforts to eradicate this practice in Canada and elsewhere.     

A Framework for Understanding Uncertainty in Seismic Risk Assessment

A better understanding of the uncertainty that exists in models used for seismic risk assessment is critical to improving risk-based decisions pertaining to earthquake safety. Current models estimating the probability of collapse of a building do not consider comprehensively the nature and impact of uncertainty. This article presents a model framework to enhance seismic risk assessment and thus gives decisionmakers a fuller understanding of the nature and limitations of the estimates. This can help ensure that risks are not over- or underestimated and the value of acquiring accurate data is appreciated fully. The methodology presented provides a novel treatment of uncertainties in input variables, their propagation through the model, and their effect on the results. The study presents ranges of possible annual collapse probabilities for different case studies on buildings in different parts of the world, exposed to different levels of seismicity, and with different vulnerabilities. A global sensitivity analysis was conducted to determine the significance of uncertain variables. Two key outcomes are (1) that the uncertainty in ground-motion conversion equations has the largest effect on the uncertainty in the calculation of annual collapse probability; and (2) the vulnerability of a building appears to have an effect on the range of annual collapse probabilities produced, i.e., the level of uncertainty in the estimate of annual collapse probability, with less vulnerable buildings having a smaller uncertainty.
