This article aims to assess why technology such as improved crop varieties has not taken off in Tanzania in spite of substantial efforts, and to consider what role policy plays in that regard. Few farmers use improved varieties due to reasons such as affordability in relation to the low profitability of farming; high risk, including fake seed in the market; and unpredictable policies and marketing opportunities. Effective governance is needed for agriculture to be transformed in the direction stated in national policy documents, but weak institutions and the collective interests of farmers not being sufficiently recognised hinder the likelihood of necessary technological changes happening.  相似文献

Among the new psychoactive substances encountered in forensic investigations is the opioid, acetyl fentanyl. The death of a 28‐year‐old man from recreational use of this compound is reported. The decedent was found in the bathroom of his residence with a tourniquet secured around his arm and a syringe nearby. Postmortem examination findings included marked pulmonary and cerebral edema and needle track marks. Toxicological analysis revealed acetyl fentanyl in subclavian blood, liver, vitreous fluid, and urine at concentrations of 235 ng/mL, 2400 ng/g, 131 ng/mL, and 234 ng/mL, respectively. Acetyl fentanyl was also detected in the accompanying syringe. Death was attributed to recreational acetyl fentanyl abuse, likely through intravenous administration. The blood acetyl fentanyl concentration is considerably higher than typically found in fatal fentanyl intoxications. Analysis of this case underscores the need for consideration of a wide range of compounds with potential opioid‐agonist activity when investigating apparent recreational drug‐related deaths.  相似文献

Footwear examination can provide an important link between the crime scene and the suspect. Casts have been taken from snow, soil, and sand substrates to assist with the examination and to accurately depict the impression. However, there has been some discrepancy on what kind of fixative, if any, should be used with impressions present in sand. This study tested four different fixatives on three sandy substrates. Eight gross characteristics were added to a boot sole, and thirty sand impressions were created in each substrate. Except for one control set that remained untreated, the impressions were treated with a fixative agent before casting. The ninety shoe casts were examined by a qualified footwear examiner and scored based on his ability to see the eight characteristics. The results indicated that pump‐action hairspray was the most successful on play and construction sand, while beach sand impressions without any fixative scored highest.  相似文献

Mental health diagnoses, substance abuse issues, and school problems are often cited as contributors to adolescents’ involvement with the juvenile justice system. Yet, few youth receive assessment, evaluation, or intervention prior to their involvement with the juvenile courts. This pilot study evaluated whether providing a randomized trial of wraparound forensic social work services in addition to court‐appointed legal services would improve functioning, decrease motions for review, and lower recidivism for first‐time juvenile offenders. Findings indicate statistically significant improvement for youth receiving wraparound services on six out of eight measures. A case study example is provided and implications for service provision are explored.  相似文献

This article examines the theory and operation of development partnerships through an analytical study of the Making Belfast Work (MBW) Initiative in Northern Ireland. This initiative of the Northern Ireland Department of the Environment contributed to the building of the current Northern Irish Peace Process. It illustrates the difficulties faced by a government in engaging in socio‐economic development in one of the world's most difficult policy environments. The history of the MBW initiative also provides insight into the interaction of two contending models for organizing European Society, namely ‘Regulated Capitalism’ and ‘Neoliberalism’ and the relationship of these models to partnership theory. This study argues that motivations for the development of partnerships in Belfast defy easy theoretical classification; yet empirical evidence suggests that a twin‐track approach—one from above, the European Union; and one from below, of indigenous policy evolution—have together through policy diffusion made MBW a leading pioneer in partnership theory and practice. The article discusses the literature on partnership within New Public Administration outlining ideas on various classifications of partnerships operative in the public sector. Particular attention is paid to how partnerships of societal actors and government can effectively involve the local community through community development approaches.

Mediation, facilitation, and other alternative dispute resolution (ADR) techniques are being used in federal agencies, state and local governments, private-sector organizations, and among private citizens in an effort to prevent and resolve disputes in a timely, cost-effective, and less adversarial manner. The U.S. Environmental Protection Agency (EPA), one of the pioneers in the application of ADR processes and techniques to public policy disputes, recently announced that it plans to in-crease the use of ADR techniques and practices across all agency programs. This article reports the results of a four-part evaluation of the use of ADR in enforcement actions at the EPA during the last two decades. Funded by the Hewlett Foundation, this effort utilized in-depth telephone interviews, government statistics, and archival records. The four groups interviewed were EPA's alternative dispute resolution specialists, potentially responsible parties (defendants) to EPA enforcement lawsuits, mediators and facilitators to EPA cases, and agency enforcement attorneys who had participated in agency enforcement ADR processes. Concluding that there are generally high levels of satisfaction with the EPA's enforcement ADR program, this article examines the sources of obstacles and assistance to ADR efforts at the EPA, suggests ways in which the EPA might improve its ADR programs, and draws lessons from the EPA's experiences that may be helpful to other public programs or organizations.  相似文献

Retribution? Restitution? Reconciliation? “Justice” comes in many forms as witnessed by the spike in war crimes tribunals, Truth &; Reconciliation Commissions, hybrid tribunals and genocide trials. Which, if any form is appropriate should be influenced by the culture of the people affected. It took Cambodia over three decades to finally address the ghosts of its Khmer Rouge past with the creation of a hybrid Khmer Rouge Tribunal. But how meaningful is justice to the majority of survivors of the Khmer Rouge auto-genocide when only a handful of top officials are tried? Further, given the persistent abuse of political and economic rights in post-conflict Cambodia, we are skeptical that justice or reconciliation is presently possible.  相似文献

Abstract:  Roughly half of filicidal acts are committed by fathers, though the majority of the literature focuses on maternal filicide. This paper reviews the existing literature on paternal filicide with the goal of identifying characteristics common among these fathers. Fathers who killed their children were, on average, in their mid thirties. The mean age of their victims was five. They may have multiple victims. Sons and daughters were killed in equal numbers. Reasons included death related to abuse, mental illness (including psychosis and depression), and revenge against a spouse. The method often involved wounding violence. Suicide following the act occurred frequently. After being tried for their crimes, filicidal fathers were more frequently incarcerated than hospitalized. Given the range of those capable of this act, mental health professionals must be alert to the possibility of filicide in a variety of fathers. Considering this risk, clinicians should inquire about thoughts of harming children, partners, and themselves.  相似文献
