A univariate time-series model is presented for projecting age- or duration-specific data for recent cohorts. The model is also capable of taking period effects into account, is illustrated using Dutch data on marital fertility rates. 相似文献

Studies investigating the connection between environmental factors and migration are difficult to execute because they require the integration of microdata and spatial information. In this article, we introduce the novel, publically available data extraction system Terra Populus (TerraPop), which was designed to facilitate population–environment studies. We showcase the use of TerraPop by exploring variations in the climate–migration association in Burkina Faso and Senegal based on differences in the local food security context. Food security was approximated using anthropometric indicators of child stunting and wasting derived from Demographic and Health Surveys and linked to the TerraPop extract of climate and migration information. We find that an increase in heat waves was associated with a decrease in international migration from Burkina Faso, while excessive precipitation increased international moves from Senegal. Significant interactions reveal that the adverse effects of heat waves and droughts are strongly amplified in highly food insecure Senegalese departments. 相似文献

The spectre of environmental ‘domestic extremism’ has long been postulated by police leaders and security analysts in Britain. It is a narrative that has justified the commitment of enormous amounts of government resources towards police intelligence work directed at non-violent direct action campaigns. Most controversially, this has included the long-term infiltration of environmental (and other) activist groups by undercover police. This article provides a critical analysis of the justifications put forward in support of the covert surveillance of environmental activists in Britain. The paper proceeds by way of a single case study – a high profile, environmental direct action protest in the north of England – in order to reveal the levels of abuse, manipulation and deception at the basis of undercover protest policing. Through their court case, the activists involved with this action were able to obtain rare insights into the police authorisation documents for the undercover operation that had led to their arrests. An analysis of these documents provides us with a glimpse of the contradictory justifications given by senior police officers for infiltration – now under scrutiny by a public inquiry. 相似文献

A jury and two valid options are given. Each agent of the jury picks exactly one of these options. The option with the most votes will be chosen by the jury. In the N-couple model of Althöfer and Thiele (Theory and Decision 81:1–15, 2016), the jury consisted of 2N agents. These agents form N independent couples, with dependencies within the couples. The authors assumed that the agents who form a couple have the same competence level. In this note, we relax this assumption by allowing different competence levels within the couples. We show that the theoretical results of Althöfer and Thiele remain valid under this relaxation. 相似文献

A global count of the extreme poor in 2012: data issues,methodology and initial results 总被引:1,自引:0,他引:1

The 2014 release of a new set of purchasing power parity (PPP) conversion factors (PPPs) for 2011 has prompted a revision of the World Bank’s international poverty line. In revising the line, we have sought to minimize changes to the real purchasing power of the earlier $1.25 line (in 2005 PPPs), so as to preserve the integrity of the goalposts for international targets such as the Sustainable Development Goals (SDGs) and the World Bank’s twin goals – which were set with respect to that line. In particular, the new line was obtained by inflating the same fifteen national poverty lines – originally used by Ravallion et al. (World Bank Econ. Rev. 23(2): 163–184 2009) to construct the $1.25 line – to 2011 prices in local currency units, and then converting them to US dollars using 2011 PPP conversion factors. With a small approximation, this procedure yields a new international poverty line of $1.90 per person per day. In combination with other changes described in the paper, this revision leads to relatively small changes in global poverty incidence for 2011: from 14.5 % using the old method to 14.1 % using the new method. In 2012, the new reference year for the global count, we find 12.7 % of the world’s population, or 897 million people, are living in extreme poverty. There are changes in the regional composition of poverty, but they are also relatively small. This paper documents methodological decisions taken in the process of updating both the poverty line and the consumption and income distributions at the country level, including issues of inter-temporal and spatial price adjustments. It also describes various caveats and limitations of the approach taken. 相似文献

Despite a number of studies investigating the effect of pharmacotherapy on treatment costs for schizophrenia patients, there has been little attention given to the effect of family intervention. In this study, data from the Kansas Medicaid system were used to analyze healthcare costs for 164 schizophrenia patients who had participated in family intervention. Structural equation modeling was used to test two competing views of the role of family intervention in treatment. The results showed that a model including direct and indirect effects of family intervention provided a better fit to the data. Family intervention had a significant indirect effect on general medical costs (through other psychological treatment) that showed a savings of $586 for each unit increase in the provision of these services. In addition, the total indirect effects for family intervention showed a $580 savings for general medical costs and $796 for hospitalization costs (for each unit increase). 相似文献

Over the last 30 years, the victims' rights movement has expanded the role of victims in the American criminal justice system. As a result of this movement, judges, prosecutors and parole boards must now hear victims' views at all stages of the criminal justice process, including plea bargains, and sentencing and parole decisions. Legislative efforts have been spearheaded by victims' families, and legislation has been named after deceased victims. Also, victims' families can now view executions in states across the country. The victims' right movement assumes that the criminal justice system should privilege victims' interests over those of society. In so doing, it denies society as a consideration, which is tantamount to a denial of society itself. This article positions victims' rights' denial of society within the current conjuncture, marked as it is by the contradiction between neoliberalism and American liberalism. Victims' rights' denial of society is an expression of the denial of society implicit in American neoliberalism, which seeks to privilege individual interests over those of society. This paper argues that victims' rights is a powerful element of the neoliberal project for three reasons. First, victims' rights imputes the authority of legal discourse to neoliberalism's denial of society. Second, important actors in the rise of neoliberalism have also worked to establish victims' rights. Finally, victims' rights comprehensively circulates throughout America and offers powerful points of identification that incorporate Americans into the victims' rights formation. I explore the denial of society in three victims' rights practices: naming criminal legislation after crime victims and passing such laws in honour of victims; allowing victims' families to view executions; and prosecutors, judges and police personnel making legal decisions according to victims' wishes. I examine the consonant denial of society in three neoliberal practices – monetarism, supply-side economics and welfare reform – and demonstrate how neoliberal advocates like Bill Clinton, Ronald Reagan and Paul Gann worked to advance victims' rights. I also describe the production, consumption and comprehensive circulation of victims' rights texts. Finally, I consider Cultural Studies' unique contribution to legal studies. 相似文献

This research uncovers a pattern of support and the existence of a relationship network that runs strongly counter to the stereotyped view that lesbians in later life find themselves friendless and without support. The hypothesis that the older lesbian has developed friendship networks to replace missing or weak kin ties is substantiated. The findings are based on 20 in-depth, structured interviews with lesbians whose ages range from 50 to 73. 相似文献
