Nearly two hundred fifty years into its existence, the American polity faces a conundrum over a core founding principle: religious liberty. Multiple debates have emerged over the extent and limits of religious liberty, including arguments over how far any one person’s religious liberty extends into the public sphere as well as into the private lives of other citizens. Highly influential on James Madison’s crafting of the First Amendment, John Locke’s Letter Concerning Toleration outlines a strong conception of both religious toleration and of religious liberty. In the “Letter,” Locke’s reasoning is sympathetic to the concerns and convictions of believers while remaining cognizant of the calamities to which religious differences can give rise. Further, he provides a robust explication of the mutually exclusive domains of ecclesiastical and civil authorities, now known more colloquially as the division of church and state. In the following article, I illustrate how the principles put forth by Locke offer guidance in adjudicating religious liberty claims in the cases of Kim Davis, religious freedom laws, vaccine refusal, contraception mandate exemptions, and ultrasound requirements.  相似文献

Are internalizing and externalizing behavior problems interrelated via mutually reinforcing relationships (with each behavior leading to increases over time in levels of the other behavior) or mutually suppressing relationships (with each behavior leading to decreases over time in levels of the other behavior)? Past research on the directionality of these relationships has led to ambiguous results, particularly in adolescence. Furthermore, the extent to which prior results will generalize to adolescents with low levels of cognitive abilities remains unknown. This second limit is particularly important, given that these adolescents are known to present higher levels of externalizing and internalizing behaviors than their peers with average-to-high levels of cognitive abilities, and that the mechanisms involved in the reciprocal relationships between these two types of behaviors may differ across both populations. This study examines the directionality of the longitudinal relationships between externalizing and internalizing behavior problems as rated by teachers across three measurement waves (corresponding to Grades 8–10) in matched samples of 138 adolescents (34.78?% girls) with low levels of cognitive abilities and 556 adolescents (44.88?% girls) with average-to-high levels of cognitive abilities. The results showed that the measurement structure was fully equivalent across time periods and groups of adolescents, revealing high levels of developmental stability in both types of problems, and moderately high levels of cross-sectional associations. Levels of both internalizing and externalizing behaviors were higher among adolescents with low levels of cognitive abilities relative to those with average-to-high levels of cognitive abilities. Finally, the predictive analyses revealed negative reciprocal longitudinal relationships (i.e., mutually suppressing relationships) between externalizing and internalizing problems, a result that was replicated within samples of adolescents with low, and average-to-high levels of cognitive ability.  相似文献

Youth’s career attainment is associated with socioeconomic background, but may also be related to their beliefs about causes of success. Relationships between 17-year-olds’ socioeconomic status (SES) and causal beliefs about success, and whether these beliefs predict career attainment after completing a vocational or university degree were examined using data from the German Socio-Economic Panel Study (n?=?997, 48.5% female). Youth with higher SES parents and those who attended higher levels of high schools were less likely to believe that success in society is due to external causes, but SES was unrelated to the belief that success is due to personal merit or ability. Youth who believe that success is due to external causes attained lower income, occupational prestige, and job autonomy, and slower increases in income over time. There were also significant indirect effects of youth’s parents’ SES and their own high school levels on career attainment through such external causal beliefs; merit beliefs, by contrast, were largely unrelated to career attainment. These results suggest that beliefs about external causes of success may uniquely contribute to the transmission and maintenance of SES across generations and over time.  相似文献

The renewed commitment of African states to modernising agriculture has reignited longstanding debates about different models of agricultural commercialisation. Which forms of commercialisation models will reduce land dispossession and the impoverishment of smallholders, and transform smallholder agriculture and the wider economy? Of the three broad models of agriculture commercialisation in this debate – plantation, contract farming and medium-scale commercial farming – contract farming has been identified as central to the future of Africa’s commercial agriculture. This paper provides empirical evidence from Ghana on the impacts of these three models on land, labour/employment, livelihoods and local economic linkages. Our findings show that the plantation and the commercial farming areas have highly commercialised land relations, land scarcity and high land prices, compared to the outgrower area where traditional systems of accessing land still dominate, enabling families to produce their own food crops while also diversifying into wage labour and other activities. Food insecurity was highest in the plantation area followed by the commercial area, but lowest in the outgrower area. Here, semi-proletarianised seasonal workers combine self-provisioning from their own farms with wages, and this results in better livelihood outcomes than for permanent workers in plantations and commercial farms. Due to the processing units in the plantation and the outgrower models, they provided more employment. However, the casualisation of labour and gender discrimination in employment and access to land occur in all three cases. All three models generated strong economic linkages mainly because they combined attributes such as processing, provided markets for nearby farmers, induced state infrastructural development and diffused technology in competitive ways. The effects of the models on household and local development are coproduced by their interaction with pre-existing conditions and wider national economic structures.  相似文献

Child abuse and neglect are complex and polarizing issues in many low and middle income countries. We explore them through a situation analysis of child rights and protection in Uganda. A qualitative study, incorporating 10 focus group discussions (FGDs; N = 113) and 20 individual interviews was undertaken in Kampala, Uganda. Emerging themes were grouped into family and community-level factors; legal framework, structure and continuum of services, and human and financial resources. Violation of child rights was characterized by physical, emotional, and sexual abuse and exploitation; child neglect, homelessness, and child labor; dysfunctional families and abject poverty; and poor accommodation conditions; school drop-out due to economic hardship; early pregnancy, and social exclusion. Legal and regulatory factors included traditional harmful practices (including child sacrifice and witchcraft practices); forced marriage; and the perceived lack of the government's commitment to child protection. Without a strong legislation that protects children against abuse, promotes confidential reporting systems, and tackles domestic violence, children will still remain prone to various forms of abuses and exploitation.  相似文献

This paper investigates to what extent socioeconomic status (SES)‐based affirmative action in college admissions can produce racial diversity. Using simulation models, we investigate the racial and socioeconomic distribution of students among colleges under the use of race‐ or SES‐based affirmative action policies, or targeted, race‐based recruitment policies. We find, first, that neither SES‐based affirmative action nor race‐targeted recruiting on their own produce levels of racial diversity achieved by race‐based affirmative action. However, the two policies in combination, although likely expensive, may yield racial diversity comparable to race‐based affirmative action. Second, the use of affirmative action policies by some colleges reduces the diversity of similar‐quality colleges without such policies. Third, the combination of SES‐based affirmative action and race recruiting results in fewer academically‐overmatched Black and Hispanic students than under race‐based affirmative action, but the schools that use both also see a reduction in the academic achievement of enrolled students.  相似文献

A hallmark finding in the study of public opinion is that many citizens approach the political realm with one‐sided attitudes that color their judgments, making attitude change difficult. This finding highlights the importance of citizens with weak prior attitudes, since they might represent a segment of the electorate that is more susceptible to influence. The judgment processes of citizens with weak attitudes, however, are poorly understood. Drawing from dual‐process models in psychology, I test the idea that citizens with weak explicit attitudes rely on implicit attitudes as they render political judgments. I find support for this conjecture in experimental and observational data. There are two main contributions. First, I show that an important and understudied segment of the electorate arrives at political decisions via automatic (but nonetheless predictable) mental processes. Second, I characterize the conditions under which implicit political attitudes matter more and less.  相似文献

Strenuous efforts by donors and lenders over four decades turned Mozambique from a socialist success story into a neoliberal capitalist one. The private sector dominates; a domestic elite dependent on foreign companies has been created. But a secret US$2.2 billion arms and fishing boat deal involving Swiss and Russian banks and Mozambican purchases from France, Germany, and Israel, with large profits on all sides, was a step too far down the donor’s capitalist road. The International Monetary Fund cut off its programme and western donors ended budget support.  相似文献

During the last decade, several formalized approaches have been developed to improve the effectiveness of probation and parole by implementing evidence-based research into community supervision practices. A key component of these new approaches are the use of officer coaching sessions, which are designed to improve officer fidelity in the core correctional skill areas. This study explores the impact of an initial training and monthly coaching sessions in the Effective Practices in Community Supervision (EPICS) model on probation and parole officer use of core correctional skills. The results examine the average quarterly officer use of skills over an 18-month follow-up period based on training status (i.e., trained versus untrained officers) in the EPICS model. This study adds to the understanding of the role training and coaching may play in improving officer use of core correctional skills. Policy implications and recommendations for future research are also discussed.  相似文献
