Preliminary evidence indicates that childhood sibling aggression, the most common form of family violence, might be associated with aggression and emotional difficulties in adulthood. Three hundred twenty-two adult participants, recruited from various sources, completed an online survey retrospectively examining this relationship further. Levels of childhood sibling aggression perpetration and victimization were highly correlated, precluding separate analyses. Significant associations between childhood sibling aggression and adult emotional difficulties and aggression were found, even after controlling for exposure to other forms of family violence and other demographic variables. Neither gender nor reported sibling relationship moderated the childhood sibling aggression and adult difficulties effects. These findings, while mostly exploratory, suggest that greater attention should be paid to childhood sibling aggression. 相似文献

Ghana has witnessed tremendous economic growth since the 1990s and attained the Millennium Development Goals target of halving poverty. This notwithstanding, inequality in Ghana increased over the same period, suggesting growth benefits were not equitably distributed. This study provides evidence on the determinants of household consumption expenditure and factors that explain rural-urban welfare gaps between 1998 and 2013. The study employs an unconditional quantile regression and recently proposed decomposition technique based on re-centred influence functions. We find significant spatial differences in consumption expenditure across selected quantiles, with rural-urban inequalities driven largely by differences in returns to households’ endowments. 相似文献

Separating the commercialisation of agriculture from other programmes to improve access to formal credit for smallholder farmers is a source of dramatic failures of most programmes. Despite the popularity of value chain financing, livestock agriculture remains marginalised. This paper analyses the MAFISA-NERPO Livestock Credit Scheme, a scheme which provides value chain financial products in order to improve the cash incomes of smallholder farmers in South Africa. Evidence shows that more than 80% of participating farmers receive average annual incomes of US$30,000. This implies that this scheme has addressed those factors hindering effectiveness and efficiency of smallholder credit institutions, using value chain finance. 相似文献

SUMMARY This case study tracks the process of the establishment of a community radio station in the Zululand area of KwaZulu-Natal, an area which is characterised by the vastly different levels of development of its constituent communities. Survey work, establishing the patterns of attention to existing media, and the question of the establishment of a community station to satisfy community communication needs are discussed. The role of the station in the areas of local governance, economic development, media training, public relations and industrial relations and language policy are examined. The findings of a survey investigating listeners' responses to the station's language policy, subsequent to the station going on the air, are also discussed. 相似文献

When a speaker injures a party through online communication, the initial inquiry becomes how and where the injured party may recover damages from the internet speaker within the constitutional limits established by the 'Due Process Clause' of the constitution on the places where a plaintiff may choose to sue a defendant. The due process limits were created to prevent a plaintiff from suing a non-resident defendant in a resident's court system unless the defendant had enough contact with the state to reasonably anticipate being sued there. As cyberspace renders moot much of the geographical principles upon which jurisdictions rely, the issue of personal jurisdiction-the involuntary imposition of a forum state's legal power-emerges as a threshold issue in the law of online expression. The following paper addresses the jurisprudence of American courts in the area of personal jurisdiction, illustrating the need for clarity in this critical area of the law. 相似文献

The right to personal data protection is, without doubt, an important right in the jurisprudence of rights in the contemporary information society. It is becoming as crucial as other orthodox human rights and also attracting significant attention from academics, lawyers, human rights activists and policy makers. In spite of the growing attention data protection receives at international and regional levels, Nigeria is still lagging behind many competitor states like South Africa in establishing an effective legal framework to protect personal data. Individuals’ personal data is being collected and used without any serious form of control to check against abuse. This paper reflects on opportunities, option and challenges to legal reforms on data protection in Nigeria. It contends that certain legislative and practical challenges stand in the way of an effective legal regime on personal data protection. The paper suggests appropriate legal reforms that are needed to enable prevent the increasing risks of violating the right to data protection in a country that is making rapid advances in Information and Communication Technology but hamstrung by an outdated regulatory framework. 相似文献
