Abstract Within the political economy of agriculture and agrofood literatures there are examples of approaches that reject simple dichotomies between alternatives and the mainstream. In line with such approaches, we challenge the assumption that alternative agriculture, and its attendant improved environmental practices, alternative management styles, less intensive approaches, and better approaches to animal and ecosystem welfare, is the only source of agricultural sustainability. This article uses national farm‐survey results for New Zealand's sheep and beef, dairy, and horticulture sectors to examine conventional farmers, measure their assessments of farming practices, and assess their environmental orientation. Analysis identifies a proenvironmental cluster of farmers in each sector characterized by a higher environmental‐orientation score and distinct ratings of other farm practices queried in the survey. We interpret the results in terms of the exposure of different agricultural sectors to the effects of market‐based, audited, best‐practice schemes. The presence of shades of “greenness” among conventional farmers has important implications for environmental management and for our understanding of the various and complex pathways toward the greening of agrofood systems.  相似文献

The survival of patients with advanced cancer, coupled with the increased presence of end-stage chronic illnesses in an aging population, is leading to a demand in palliative care. Due to the ongoing need for acute-pain and symptom control in hospice/palliative care units, few are able to offer long-stay admission for those whose symptoms have stabilized. When a patient no longer requires specialist palliative care services, transfer from an inpatient palliative care facility may then be necessary. A core component of the role of palliative-care social workers involves working with patients and their families/carers when the care pathway shifts and the option of residential aged care facility (RACF) needs to be considered. This research explored several issues, including the impact of this transition on the patient and their families and on the interdisciplinary health care team treating the patient. An investigation was undertaken to identify concerns and barriers regarding the transition from hospice care to RACF and opportunities were highlighted to improve clinical practice in this area. A tripartite approach was adopted conducting face-to-face interviews with patients, their families/carers, and health care professionals. Members of the interdisciplinary team were interviewed and social workers working in similar inpatient palliative-care facilities undertook telephone interviews to gauge their experiences. A thematic analysis discerned a number of themes highlighting the impact of this transition on key stakeholders and incorporated recommendations to improve or best manage this process. The research has highlighted the difficulties that patients/families encounter in this transition, as well as the emphases of protecting the integrity of the patient and family. This is achieved by holding open and ongoing dialogue, particularly through family meetings and working in collaboration with the patient, the family, and the team. Understanding the experience and impact of this transition on key stakeholders is helpful in building up a knowledge base and to ensure a more effective relationship occurs. This research incorporated the voices of terminally ill patients, families, and members of the health care team in order to understand their views and recommendations for best managing the transition from a hospice/inpatient palliative-care facility to a RACF. This enables their input to have some real impetus in clinical practice and service delivery.  相似文献

Abstract

This research evaluates the impact of family structure on the educational attainment of northern urban blacks. Separate analyses of male and female adults reveal little support for the traditional view that the “broken home” lowers the achievement of black males. Rather, we find it is black females, especially in segregated contexts, who have been most adversely affected by parental absence. These findings are interpreted as reflecting the different relationship of males and females to the family under conditions of structurally-induced poverty.  相似文献

Ipsilateral breast tumor relapse (IBTR) often occurs in breast cancer patients after their breast conservation therapy. The IBTR status' classification (true local recurrence versus new ipsilateral primary tumor) is subject to error and there is no widely accepted gold standard. Time to IBTR is likely informative for IBTR classification because new primary tumor tends to have a longer mean time to IBTR and is associated with improved survival as compared with the true local recurrence tumor. Moreover, some patients may die from breast cancer or other causes in a competing risk scenario during the follow-up period. Because the time to death can be correlated to the unobserved true IBTR status and time to IBTR (if relapse occurs), this terminal mechanism is non-ignorable. In this paper, we propose a unified framework that addresses these issues simultaneously by modeling the misclassified binary outcome without a gold standard and the correlated time to IBTR, subject to dependent competing terminal events. We evaluate the proposed framework by a simulation study and apply it to a real data set consisting of 4477 breast cancer patients. The adaptive Gaussian quadrature tools in SAS procedure NLMIXED can be conveniently used to fit the proposed model. We expect to see broad applications of our model in other studies with a similar data structure.  相似文献
