This paper analyses the impact of a low-cost land certification programme on the productivity of female-headed households. The hypotheses tested in the paper emphasise on the interaction between the constraints that female-headed households face in terms of insecure land tenure, lack of productive resources and suboptimal land market participation, on the one hand, and the tenure security benefits of certification on the other. Our findings show that land certification has a positive effect on land market participation and productivity. Our analysis also suggests higher marginal effects of certification on female-headed households’ productivity, compared to the male ones. 相似文献

It is generally held that one mechanism to enable inclusive growth in Tanzania is enabling farmers to access credit to raise productivity and incomes. The formalisation of property rights in Tanzania is being undertaken by a multiplicity of actors at great expense to donors, individuals and the government. While there have been a variety of different justifications for allocating Certificates of Customary Rights of Occupancy (CCROs) to farmers in Tanzania, perhaps the most prominent argument is that it will enable farmers to finally overcome the divide between ‘informal’ customary rights and the formal banking sector. CCROs would provide the collateral that would induce banks to lend money to small-scale farmers. As part of a six-year investigation in Manyara, Mbeya and Dodoma regions, our research team evaluated the impact of formalisation on farmers’ access to credit. The paper will present the results while pointing to the continuing institutional and market imperfections that perpetuate the formal divide. 相似文献

Prior research suggests that being abused during childhood significantly increases one’s risk for the involvement in violent intimate relationships across the life course. The current study contributes to the literature by using a large sample of college students to explore the moderating effects of race and gender on the relationship between child abuse and later experiences of intimate partner violence. Results indicate that for both men and women, child abuse increases the risk for dating violence. Findings also suggest that specific race and gender combinations moderate the relationship between child abuse and later experiences of IPV, specifically regarding the risk for mutual or bidirectional violence. Implications for prevention and intervention and directions for future research are discussed. 相似文献

A detailed, correlative, histologic evaluation of postmortem changes in the nasal mucosa of chronic cocaine users has shown characteristic mucosal and arteriolar changes as well as typical perivascular and subepithelial alterations compatible with chronic inflammation. These findings confirm and extend recent reports on the effects of cocaine in the coronary circulation and heart muscle as well as provide a new diagnostic tool to the forensic pathologist who suspects that a decedent has been a long-term cocaine abuser. 相似文献

A general toxicology unknown case is presented to demonstrate our systematic approach. A 20-year-old male was found dead with multiple suicide notes. Overdose was suspected but substances were not known. Blood alcohol was negative. Urine was analyzed by enzyme-multiplied immunoassay technique and was negative for all drugs assayed. Urine was then extracted with ethyl acetate:hexane (1:1) at pH 10 and back-extracted into 1.0N sulfuric acid. The acidic layer was adjusted to pH 10, and re-extracted with ethyl acetate:hexane (1:1). The residue was analyzed by gas chromatography (GC) on a 3% OV-101 column. It was found to be negative for all commonly screened substances. However, several unknown peaks were observed. Electron impact mass spectra of these unknown peaks were obtained and searched for in our computer library of more than 25000 mass spectra. These unknown peaks were identified as doxylamine and pyrilamine by gas chromatography/mass spectrometry. The base peak and molecular ion for pyrilamine were at m/z 121 and 285, respectively. The base peak for doxylamine was at m/z 58. No molecular ion was observed for doxylamine. Both doxylamine and pyrilamine are antihistamines, but are promoted and used in the management of insomnia. Quantitation was performed on a GC using dexbrompheniramine as an internal standard. Blood concentrations for doxylamine and pyrilamine were 0.7 and 7.0 mg/L, respectively. Concentrations in other tissues were determined. Death was caused by combined doxylamine and pyrilamine intoxication; the manner of death was suicide. 相似文献

Tenure Insecurity,Gender, Low-cost Land Certification and Land Rental Market Participation in Ethiopia 总被引:2,自引:0,他引:2
There is a renewed interest in whether land reforms can contribute to market development and poverty reduction in Africa. This paper assesses effects on the allocative efficiency of the land rental market of the low-cost approach to land registration and certification of restricted property rights that was implemented in Ethiopia in the late 1990s. Four rounds of a balanced household panel from 16 villages in northern Ethiopia are analysed, showing that land certification initially enhanced land rental market participation of (potential) tenant and landlord households, especially those that are headed by females. 相似文献

Extant research regarding juvenile transfer has focused primarily on the negative effects of current policies, with little
consistent and rigorous work on the variation among the adolescents transferred to adult court and their later adjustment
in the community. Using a sample of 193 transferred youth from Arizona, we consider how certain individual characteristics
are related to four post-release outcomes (antisocial activity, re-arrest, re-institutionalization, and gainful activity).
We find considerable variability in outcomes, with adjustment significantly and consistently related to certain legal and
risk-need factors. These results indicate that some transferred youth may experience negative outcomes, and that refinements
to transfer policy may benefit from consideration of these factors in determining which serious adolescent offenders are most
appropriate for transfer. 相似文献
