The Child's Attorney and the Alienated Child: Approaches to Resolving the Ethical Dilemma of Diminished Capacity

Increasingly lawyers for children follow a model of “client centered” (as opposed to “best interests”) representation in child custody disputes in which the child client defines the objectives of the representation. The client‐centered model, while appropriate in most cases to give voice to the child's preferences in a process that deeply impacts him or her, can create an ethical dilemma for the child's lawyer in cases where a child is truly alienated from the other parent by the actions of the alienating parent. Alienated children strongly and unreasonably express a preference for objectives of representation that might further damage the alienated parent's relationship with the child. The alienated child's objectives may be the result of a campaign of denigration and “brainwashing” by the alienating parent. This Note suggests that when a child is truly alienated from a parent, as diagnosed by a mental health expert, the child may have “diminished capacity” and therefore, the client‐directed model of representation is not adequate. This Note proposes that the Child's Attorney must determine whether the child is of diminished capacity under the Model Rules of Professional Conduct and, if so, must treat the client accordingly under Rule 1.14. Specifically, the attorney may, if all other remedial measures are inadequate, override the child's wishes and advocate a position that the child would take, but for the brainwashing of the child used to alienate him or her from a parent.

Evolution of input supply and service hubs in dairy development at Ada'a milk shed in Ethiopia

Efficient input supply and service delivery may call for a hub approach where all the necessary inputs and services are supplied in a coordinated manner, either by a single supplier or by several and separate entities in a given geographical location accessible to beneficiaries. Based on experience from Ada'a milk shed in central Ethiopia, this paper assesses the evolution of input supply and service provision in the dairy sub-sector, focusing on coordination and the degree of competition among different actors at different levels in the value chain over time. Data were collected from key value chain actors engaged in provision of input supply and output marketing services in Ada'a milk shed. The major lesson is that the development of coordinated input supply and service delivery by different business entities or under a single business entity may not emerge at once, but through a gradual evolution. This depends on the level of demand for the inputs and services as determined by the degree of demand for milk and milk products, and the economies of scale input suppliers and service providers could attain from the expansion of demands for these inputs and services. Moreover, at the early stage of a hub development, collective actions and integration of services and marketing within a business organisation could be the main strategy to attain efficiency. But, once the demand for inputs and services has grown, competition among different entities will lead to more efficient input supply and service delivery. In general, where there is an increasing demand for inputs and services, there is a faster development of input supply and service provision by private actors and collective actions in a more competitive way. Role of the public sector could change gradually from provision of inputs and services to coordination, capacity building, quality control, and regulation.

Évolution des plateformes d'approvisionnement en intrants et de services dans le développement du secteur de la production laitière dans la laiterie d'Ada'a, en Éthiopie

Pour une fourniture d'intrants et une prestation de services efficaces, il peut se révéler nécessaire de mettre en ?uvre une approche axée sur une plateforme dans le cadre de laquelle tous les intrants et services nécessaires sont fournis de manière coordonnée, soit par un fournisseur unique soit par plusieurs entités séparées, dans un lieu donné accessible aux bénéficiaires. Sur la base de l'expérience de la laiterie d'Ada'a, en Éthiopie, cet article évalue l'évolution de la fourniture d'intrants et de la prestation de services dans le sous-secteur laitier, en se concentrant sur la coordination et sur le degré de concurrence entre différents acteurs et à différents niveaux de la chaîne de valeur au fil du temps. Des données ont été recueillies auprès d'acteurs clés de la chaîne de valeur actifs dans la fourniture d'intrants et dans la prestation de services de commercialisation de la production dans la laiterie d'Ada'a. Le principal enseignement est que le développement d'une fourniture d'intrants et d'une prestation de services coordonnées par différentes entreprises ou dans le cadre d'une entité commerciale unique peut ne pas avoir lieu tout d'un coup, mais au fil d'une évolution progressive. Cela dépend du degré de demande concernant les intrants et les services, tel que déterminé par le degré de demande de lait et produits laitiers, et par les économies d'échelle que les fournisseurs d'intrants et les prestataires de services pourraient obtenir grâce à l'expansion de la demande de ces intrants et services. De plus, au stade initial de la mise en ?uvre d'une plateforme, les actions collectives et l'intégration des services et de la commercialisation dans une organisation commerciale pourraient constituer la principale stratégie pour arriver à l'efficacité. Mais, une fois que la demande en intrants et en services s'est accrue, la concurrence entre différentes entités engendrera une fourniture d'intrants et une prestation de services plus efficaces. En général, lorsqu'il y a une demande croissante d'intrants et de services, il se produit un développement plus rapide de la fourniture d'intrants et de la prestation de services par des acteurs privés dans une optique plus concurrentielle. Le rôle du secteur public pourrait évoluer progressivement, de la fourniture d'intrants et de services à un rôle de coordination, de renforcement des capacités, de contrôle de la qualité et de réglementation.

Evolución de la oferta de insumos y de los centros de servicios en el desarrollo de lácteos en la cuenca lechera de Ada en Etiopía

Para llevar a cabo de manera eficiente la oferta de insumos y la entrega de servicios puede requerirse un centro de servicios cuya ubicación sea accesible a los beneficiarios, a partir del cual los mismos sean suministrados de manera coordinada, ya sea a través de un proveedor único, o bien, a través de varios entes separados. Apoyándose en la experiencia de la cuenca lechera de Ada, localizada en el centro de Etiopía, el presente artículo valora la evolución de la oferta de insumos y de la entrega de servicios en el subsector de lácteos, centrándose en la coordinación y en el grado de competitividad mostrado durante varios años por distintos actores ubicados en diferentes estratos de la cadena de valor. La información fue recopilada de actores clave de la cadena de valor en la cuenca lechera de Ada, quienes proveen insumos y servicios de comercialización de productos. El aprendizaje más importante que ha dejado esta experiencia es que: el desarrollo de la oferta de insumos y de la entrega de servicios – realizadas de manera coordinada por distintas empresas o por una sola – puede no surgir inmediatamente, sino después de una lenta evolución. Ello depende del nivel de demanda de insumos o servicios que, a su vez, depende tanto de la demanda de leche y de productos lácteos como de las economías de escala que pudieran obtener sus proveedores a partir de la expansión de la demanda de estos productos. Asimismo, durante las etapas iniciales del desarrollo de un centro de servicios, las acciones colectivas, la integración de servicios y la comercialización centradas en una sola empresa, podrían constituir la estrategia más importante para mejorar la eficiencia. Sin embargo, una vez que la demanda de insumos y servicios haya crecido, la competencia entre distintas entidades producirá una oferta y una entrega de los mismos más eficiente. En general, en aquellos lugares en que exista una demanda creciente, habrá un desarrollo más rápido de la oferta de insumos y de la entrega de servicios por parte de los actores privados, además de acciones colectivas más competitivas. En consecuencia, el rol del sector público podría modificarse gradualmente, pasando de ser proveedor de insumos y servicios a ser la instancia que coordine, fortalezca capacidades y vigile el control de calidad y las normas.

Evolução dos centros de abastecimento de insumos e serviços no desenvolvimento do setor de laticínio da região produtora de leite de Ada'a, na Etiópia

Uma oferta eficiente de insumos e de serviços pode demandar um centro em que todos os insumos e serviços necessários sejam ofertados de maneira coordenada, seja através de um único fornecedor ou de várias entidades separadas em uma dada área geográfica acessível aos beneficiários. Com base na experiência da região produtora de leite de Ada'a situada na região central da Etiópia, este artigo avalia a evolução da oferta de insumos e de serviços no sub-setor de laticínios, concentrando-se na coordenação e grau de competição entre diferentes agentes em níveis diferentes da cadeia de valores no decorrer do tempo. Os dados foram coletados a partir de agentes-chave da cadeia de valores engajados na oferta de insumos e serviços de marketing na região produtora de leite de Ada'a. A principal lição é que o desenvolvimento da oferta coordenada de insumos e de serviços através de diferentes entidades empresariais ou através de uma única entidade empresarial pode não surgir de uma só vez, mas sim ter uma evolução gradual. Isto depende do nível de demanda dos insumos e serviços, que é determinado pelo grau de demanda de leite e de produtos lácteos, e as economias de escala que os fornecedores de insumos e de serviços podem obter a partir da expansão de demandas por estes insumos e serviços. Além disto, na fase inicial do desenvolvimento de um centro, ações coletivas e integração de serviços e marketing dentro de uma organização empresarial podem ser a estratégia principal para se obter eficiência. Porém, após a demanda por insumos e serviços ter crescido, a competição entre entidades diferentes levará a uma oferta de insumos e de serviço mais eficiente. Em geral, quando há uma demanda crescente por insumos e serviços, há um desenvolvimento mais rápido na oferta de insumos e serviços por agentes privados e ações coletivas mais competitivas. O papel do setor público poderia mudar gradualmente da oferta de insumos e serviços para a coordenação, capacitação, controle de qualidade e regulação.     

对2005年英国《意思能力法》的再解读——以社会工作为视角

2005年英格兰和威尔士颁行的《意思能力法》将判例法的大部分实践奉为准则以保护丧失决策能力的成年人,促进个人自主性以及确保个人能够提前做出拒绝治疗的相关决定.它在需要替欠缺行为能力成年人做主要的身体和福利决定的情形下引入了新的替代决策方式以满足这些需求以及相关特殊主张.2005年《意思能力法》的适用范围从不同的角度得到再次解读,此法与在既定领域以新角色与他人进行合作的社会工作者之间的密切关系得到考察,社会工作者的部分责任得到阐明,研究结论指出：社会工作者具备完美实践的潜力,而这也需要专业的反思与服务监督的支持.

The Law and Incapacity Determinations: A Conflict of Governance?

This article will consider the highly charged questions raised by two major sets of law reforms in England and Wales, the Mental Capacity Act 2005 and the Mental Health Act 2007, which, although applying to closely related clinical populations, proceeded along entirely separate legislative paths. By justifying its proposals for reform of mental health legislation on the grounds of 'risk', the Government failed to take into account the implications of enforced treatment on patients who may retain decision-making capacity.     

Ruralisation: a tool for rural transformation

There is a concept that development practitioners have either not heard of or not read, or have chosen to ignore – ruralisation. Unlike urbanisation in urban studies, ruralisation is rarely used as a concept in rural research. It remains a poorly explored concept. By challenging existing notions about the use of the concept, this article attempts to (re)introduce ruralisation as a fundamental concept in rural studies. What is ruralisation? Why do we need it? How can we use it for rural transformations? The article addresses these critical questions. It defines ruralisation and presents its conceptual framework for rural transformation.     

Utilizing Hyperlink Network Analysis to Examine Climate Change Supporters and Opponents

Hyperlink network analysis, which utilizes the links between websites to map online communication structures, offers an emerging methodology for studying the networks of supporters and opponents of public policies. Reasons for the methodology's appeal include the ability to utilize web crawlers to collect large amounts of data and the ability to apply quantitative and qualitative methods to examine network interactions. While the methodology has been utilized by diverse disciplines it is relatively new to the fields of political science and public policy. Utilizing a mixed‐methods research design, this article examines the applicability of using hyperlink networks to study opposing groups in the Colorado climate and energy policy subsystem while drawing increased attention to the methodology's strengths and weaknesses. The results demonstrate the methodology's considerable potential, but highlight the need for greater adoption of a collection of best practices designed to increase the validity, reliability, and generalizability of hyperlink research.     

Does the Statutory Regulation of Advance Decision-Making Provide Adequate Respect for Patient Autonomy?

This paper considers advance decision-making in the context of healthcare. The common law recognition of advance decisions is contrasted with new statutory provision. This paper will examine the Mental Capacity Act 2005 framework for advance decisions and lasting powers of attorney. The ‚best interests’ test and substituted judgment as criteria for proxy decision-making are compared by application to a case example. The paper examines the statutory safeguards in respect of refusals of ‚life-sustaining treatment’ and postulates that these safeguards may render respect for autonomous advance decision-making difficult to achieve in practice.
