This article is part of a broader research project which seeks to shed new light on Quebec's fertility decline between the 1850s and the 1950s, notably by breaking down barriers between cultural and economic explanations and between quantitative and qualitative analysis. It explores relationships between demographic trends and the public discourse around reproduction in the province at the turn of the twentieth century. Using a collection of articles selected from French-language periodicals published between 1870 and 1920, the article analyzes the reactions of certain public commentators to the prospect of fertility decline in this traditionally prolific province. They identify a shift in the public discussion of fertility in Quebec during World War I. Pride in and celebration of Quebec's large families was superseded in the dominant nationalist discourse by anxiety about diminished rates of reproduction and natalist exhortations to women who might be tempted to restrict their fertility. After documenting and identifying the reasons for this shift, the article discusses a current of opposition which appeared, if only briefly, in the pages of the controversial liberal weekly, Le Pays.  相似文献

Models of voting behavior typically specify that all voters employ identical criteria to evaluate candidates. We argue that moderate voters weigh candidates’ policy/ideological positions far less than non-moderate voters, and we report analyses of survey data from the 2010 Cooperative Congressional Election Study that substantiate these arguments. Across a wide range of models and measurement strategies, we find consistent evidence that liberal and conservative voters are substantially more responsive to candidate ideology than more centrist voters. Simply put, moderate voters appear qualitatively different from liberals and conservatives, a finding that has important implications for candidate strategies and for political representation.  相似文献

Children of incarcerated parents are exposed to factors that place them at risk for delinquency. Few studies have examined the effects of having an incarcerated parent after controlling for other experiences such as contextual risk factors and family processes. Past studies have also not examined effects of recent, but not current, parental incarceration on children. The present study examines an archival dataset, in which children aged 10–14 years and their parents/guardians reported children’s risk experiences (e.g., exposure to poverty, parental substance use), family processes (e.g., level of family victimization, family conflict), and children’s delinquent behaviors at two time points. Parents also reported their recent and past incarceration history. Hierarchical linear regression analyses show that a history of parental incarceration predicted family victimization, delinquent behaviors of children’s older siblings, and delinquent behaviors of the child participants, over and above children’s demographic characteristics and other risk experiences. Recent parental incarceration predicted family conflict, family victimization, and parent-reports of children’s delinquency after also controlling for previous parental incarceration. The role of family processes in research and intervention directions involving children of incarcerated parents is discussed.  相似文献

Successful academic performance during adolescence is a key predictor of lifetime achievement, including occupational and social success. The present study investigated the important transition from primary to secondary schooling during early adolescence, when academic performance among youth often declines. The goal of the study was to understand how risk factors, specifically lower family resources and male gender, threaten academic success following this “critical transition” in schooling. The study involved a longitudinal examination of the predictors of academic performance in grades 7–8 among 127 (56 % girls) French-speaking Quebec (Canada) adolescents from lower-income backgrounds. As hypothesized based on transition theory, hierarchical regression analyses showed that supportive parenting and specific academic, social and behavioral competencies (including spelling ability, social skills, and lower levels of attention problems) predicted success across this transition among at-risk youth. Multiple-mediation procedures demonstrated that the set of compensatory factors fully mediated the negative impact of lower family resources on academic success in grades 7–8. Unique mediators (social skills, spelling ability, supportive parenting) also were identified. In addition, the “gender gap” in performance across the transition could be attributed statistically to differences between boys and girls in specific competencies observed prior to the transition, as well as differential parenting (i.e., support from mother) towards girls and boys. The present results contribute to our understanding of the processes by which established risk factors, such as low family income and gender impact development and academic performance during early adolescence. These “transitional” processes and subsequent academic performance may have consequences across adolescence and beyond, with an impact on lifetime patterns of achievement and occupational success.  相似文献

Abstract

Although there is substantial attention to judicial decision-making during sentencing, fewer studies have examined decision-making post sentencing. Further, the interactions of probationer race and additional background factors have been under studied in post-sentencing decision-making. This study utilizes the focal concerns perspective to examine whether race interacts with gender, family status, and employment status in predicting sanctioning probationers for noncompliance. A sample of probation review hearings within an eight-month period in three domestic violence courts were selected. Results demonstrate that race does not interact with other background factors in influencing a jail sanction, while non-compliant behaviors are the strongest predictors.  相似文献

Rwanda is not a traditional provider of troops for peacekeeping missions, yet since 2004 it has been the second largest contributor to both the African Union Mission in Sudan (AMIS) and its successor the hybrid African Union–UN Assistance Mission in Darfur (UNAMID). This paper analyses some of the key motives for Rwanda's contribution to these missions, situating its actions within a wider framework in which African states benefit in specific ways from being seen to contribute to ‘African solutions to African problems’. Highlighting changing narratives on Africa's role in international security, I argue that Rwanda's ruling party has been able use its involvement in peacekeeping to secure its position domestically and to attract or retain the support of key bilateral donors. I briefly explore the implications of these dynamics for Rwanda's political development, suggesting in conclusion that the focus on building military capacity for peacekeeping purposes may contribute to future African, and Rwandan, security problems as much as to potential solutions.  相似文献

Sex determination is of paramount importance in forensic anthropology. Numerous anthropological methods have been described, including visual assessments and various measurements of bones. Nevertheless, whatever the method used, the percentage of correct classification of a single bone usually varies between 80% and 95%, due to significant intra- and inter-population variations, and sometimes variations coming from secular trends. DNA is increasingly used in a forensic context. But forensic DNA extraction from bone raises several issues, because the samples are very often badly altered and/or in very small quantity. Nuclear DNA is difficult to get from degraded samples, according to low copy number, at least in comparison with mitochondrial DNA. In a forensic context (as in a paeleoanthropological context) DNA sex determination is usually complicated by the weak amount of DNA, the degraded nature of nucleic acids, the presence of enzymatic inhibitors in DNA extracts, the possible faint amplification of Y band and the risk of contamination during either excavation or manipulation of samples.The aim of this work was to compare three methods of DNA sex determination from bones: procedure #1 using a single PCR amplification, procedure #2 using a double PCR amplification, and procedure #3 adding bleaching for decontamination of the bone, instead of simply rubbing the bone. These processes were applied to samples of bones (49 samples coming from 39 individuals) that were in various states of post mortem alteration.The main results are the following. (i) No DNA could be extracted from three skulls (parietal bones, mastoid process), the compact bone of one rib, and the diaphysis of one femur; (ii) there was a contamination in three skulls; and (iii) the Y band did not appear in two male cases, with one of the three procedures (male tibia, procedure #2) and with procedures #2 and #3 (male femur).This study emphasises the main issue while working with altered bones: the impossibility to extract DNA in some cases, and, worth of all, the contamination of the sample or the faint amplification of Y band which leads to a wrong sex answer. Multiple and significant precautions have to be taken to avoid such difficulties.  相似文献
