Pioneering research on downstream linkages from agriculture is said to demonstrate that consumption links rather than production links are the main source of indrect growth effects, that these consumption links take the form of labour‐intensive goods and services produced locally, and that the largest farm enterprises are most locally multiplicative of activities mopping up surplus rural labour. This article has two purposes. First, the methodologies, assumptions and data base for the quantification of the local and non‐local regional multiplier effects from agricultural development are examined. Second, the contradictory interpretations for agricultural policy which have arisen from these exercises of quantification are discussed and an attempt made to explain their bases. 相似文献

The Mystery Man Can Increase the Reliability of Eyewitness Identifications for Older Adult Witnesses
Catriona Havard Phyllis Laybourn Barbara Klecha 《Journal of Police and Criminal Psychology》2017,32(3):214-224
Some groups of eyewitnesses, such as older adults and children, are less likely to correctly reject a target-absent (TA) line-up, as compared to younger adults. Previous research reports that using a silhouette in a video line-up called the ‘mystery man’ could increase correct rejections for TA lineups for child eyewitnesses, without reducing correct identifications for target-present (TP) line-ups (Havard and Memon in Appl Cogn Psychol 27:50–59, 2013). The current study, using older and younger adults, investigated whether using the mystery man would also increase the identification accuracy for older adults, without impairing younger adults’ identification accuracy. The results found that older adults in the ‘mystery man’ condition rejected TA line-ups significantly more often than those in the control condition (52 vs. 24 %), with no significant effect upon the TP line-ups. For the younger adults, the mystery man had no influence on identification responses for the TA or TP line-ups. Our findings suggest the mystery man technique may be beneficial for older adults, without detrimentally affecting the accuracy for younger adults, and thus could increase the reliability of eyewitness evidence, where video line-ups are employed. 相似文献

The potential for the injury or death of a child resulting from the tip-over of a piece of household furniture or a domestic appliance has not been previously well recognized. We reviewed nine accidental deaths of young children that resulted from avoidable residential hazards and/or lapses in supervision of the children by their caregivers. The offending household items included televisions, bedroom dressers, a kitchen stove, and a lounge chair. The causes of death were mechanical asphyxia, blunt trauma, and combined blunt head trauma and asphyxia. All of the deaths could have been prevented by appropriate anchoring of the piece of furniture and/or closer supervision of the child. A thorough multidisciplinary investigation is essential in establishing the cause and manner of death in such cases and in identifying risk factors that may aid in the prevention of future childhood deaths. 相似文献

Myiasis is defined as an infestation of the organs and/or tissues of human and other animals by fly maggots. Fly species that normally breed in meat or carrion (Diptera: Calliphoridae, Sarcophagidae) may become involved in cutaneous myiasis by colonizing preexisting wounds. Reports of human wound myiasis contracted in hospitals and nursing homes, especially when patients are chronically ill or bed-ridden, are not uncommon across North America and often result in cases of neglect and civil litigation. Based on a case history dealing with this latter situation and circumstances surrounding the treatment of maggot infestation, we designed an experiment to assess the effectiveness of wound cleansing solutions on maggot mortality. Treatments, consisting of four commonly used cleaning solutions (isopropyl alcohol, Dakin's solution, iodine, and hydrogen peroxide) and a control (deionized water), were applied to experimental units (n=5), with each unit consisting of groups of actively feeding Lucilia sericata maggots (Diptera: Calliphoridae). Every 24h, treatments were applied and mortality was assessed for the duration of the study (14 days). Total mean mortality increased over the duration of the experiment, with an initial large increase (10-25%) after the first treatment application, followed by a gradual increase over the remainder of the study. General differences among treatments indicated greatest mean total mortality for Dakin's solution (sodium hypochlorite) (46%), followed by isopropyl alcohol (42%), Betadine (37%), hydrogen peroxide (33%) and lowest mortality for the control (25%); however, no statistically significant differences were observed among treatments and no treatment resulted in 100% maggot mortality. Traditional wound cleansing solutions may not be sufficient for maggot infestations of pre-existing wounds and supplemental treatments may be necessary to effectively treat cases of wound myiasis. 相似文献

Lieberman and Zeanah are specialist clinicians, researchers, and prolific publishers in the areas of infant mental health, attachment development in high‐risk environments, and treatment of infant–parent relationship trauma. In this article, Lieberman and Zeanah discuss the impacts of domestic violence on the attachment security and development of infants and children and address a number of implications for the family law context. Conundrums for parenting visitation and living arrangements are considered, together with the need for multidisciplinary, early response and the pivotal role of family courts in directing this response. 相似文献

Homeowners associations (HOAs) are private governments that are reshaping urban governance and service delivery in large parts of the United States. Despite the fact that millions of Americans are HOA members, the field of public affairs has paid scant attention to these new governance entities. The essays in this symposium call attention to HOAs’ potential effects on urban services and civic life in the hope of sparking interest among scholars and public managers to include HOAs in our understanding, research, and teaching of contemporary urban governance. 相似文献

Although research into the phenomenon of serial murder has revealed that serial killers frequently do not fit the initially described paradigm in terms of their physical and psychological profiles, backgrounds, and motives to kill, the media continues to sensationalize the figures of such killers and the investigators who attempt to analyze them on the basis of aspects of their crimes. Although the so-called "typical" profile of the serial murderer has proven accurate in some instances, in many other cases the demographics and behaviors of these killers have deviated widely from the generalized assumptions. This report details two unusual cases in which five and eight murders were committed in upstate New York. The lives and crimes of these offenders illustrate the wide spectrum of variations in the backgrounds, demographics, motivations, and actions witnessed among serial murderers, and highlight the limitations and dangers of profiling based on generalities. 相似文献
