This paper asks why it took ten years after a major famine in Indonesia in 1957 for Australia's food aid to increase in greater amounts, and why food aid was so significant in Australia's foreign aid to Indonesia during the late 1960s and 1970s. Indonesia's reluctance to apply for food aid under the Colombo Plan is the reason for the delay. A combination of humanitarian, commercial and international relations interests converged to shape Australia's rapidly growing food aid to Indonesia after 1966. Food aid contributed to alleviating food shortages and famines in Indonesia. It also supported Australian firms in regaining their share in the growing market for wheat-based products in Indonesia, and in building market share for Australian rice exports, in competition with United States (US) producers and the US PL480 food aid program. Food aid also allowed Australia to expand its foreign aid program to Indonesia rapidly after 1966, in support of the government of new President Soeharto and improved bilateral relations.  相似文献

Black Economic Empowerment (BEE) is an attempt to marry redistributiveand neo-liberal economic policies. The South African state,however, has differing degrees of power to force redistributionon different sectors of the economy. Fisheries is one of thesectors where state allocation of licenses, exploitation rightsand quotas makes the prospects for BEE promising. In this article,we examine redistributive processes in the hake trawl industry.We conclude that BEE, despite its redistributive intentions,has been doubly conducive to the interests of large-scale SouthAfrican capital. To begin with, it has by and large confirmedthe historical share of fishing rights to incumbent, largelywhite-controlled, operators. Second, it has created a layerof ‘black captains of industry’ to whom incumbentsare increasingly outsourcing primary production in a volatile,high-risk and currently loss-leading sector. While fishing operationsare being outsourced under the banner of redistribution, thefish trade remains under the effective control of white capital.  相似文献

With deeper integration into the global economy and expanded penetration by multinational firms and other nonChinese actors following accession to the WTO, skills in bureaucratic entrepreneurship are not likely to be sufficient by themselves to bring about China’s sustainable development. In today’s interdependent and highly competitive trade, economic-cooperation, and resource-limited environment, sustainable development requires that subnational managers also possess transnational competence in collaborating with, negotiating with, and transforming foreign counterparts. However, survey research among Chinese executives based in Shanghai revealed that only a small proportion of the reporting current and future managers recognized the growing importance for China of an interculturally competent workforce. Without increased attention to enhancing the transnational competence of government and state-enterprise managers, peaceful and ecologically sound development will be difficult to sustain given the demands of multinational production chains, global resource constraints, and the challenges involved in managing transnational relations in the interest of China’s long-term economic progress.

In September 2019, the U.K. House of Commons Environmental Audit Committee warned that the United Kingdom's food supply was vulnerable to climate change. Within the U.K. food retailing is highly concentrated with the four leading food retailers accounting for almost 70% of all food sales. In the face of the threat of climate change to food supplies, a focus on resilience might be seen to have much to offer retailers. However, little work has been published in the academic literature on if, and how, retailers are employing the concept of resilience in their business plans. With these thoughts in mind, this commentary paper provides an exploratory review of how the United Kingdom's four leading food retailers, namely Tesco, Sainsbury's, Asda, and Morrisons, have publicly acknowledged the importance of resilience in the face of climate change. The paper outlines definitions of resilience and retail resilience, draws out four general themes within the U.K. food retailers' resilience plans, and offers some wider reflections on the retailers' resilience plans in the face of climate change.  相似文献

As relationships between people and nature are being reassessed, not least as concerns about climate change gather increasing momentum, so a range of environmental and conservation themes are moving up public and political agendas. Rewilding, simply defined as increasing the role of natural processes within landscapes, is one such theme. This commentary paper outlines the variety of definitions and origins of the concept of rewilding, illustrates some of the elements of rewilding within Europe, and offers some general reflections on the rewilding process. The paper suggests that although many benefits have been claimed for moves to increase the role of natural processes within landscapes and environments, rewilding faces several challenges, in that it means different things to different people, public perceptions of rewilding can generate unease, hostility, and concern and it has only limited scientific support. At the same time, there is no clear statutory policies to guide the rewilding process. As such, rewilding organisations may increasingly look to communication and public relations to garner public and financial support for their cause.  相似文献

Postmortem computed tomography (PMCT) is integrated into the evaluation of decedents in several American medical examiner offices and medicolegal death investigative centers in many other countries. We retrospectively investigated the value of PMCT in a series of firearm homicide cases from a statewide centralized medical examiner’s office that occurred during 2016. Autopsies were performed or supervised by board-certified forensic pathologists who reviewed the PMCT scans prior to autopsy. PMCT scans were re-evaluated by a forensic radiologist blinded to the autopsy findings and scored by body region (head–neck, thoracoabdominal, and extremities). Injury discrepancies were scored using a modified Goldman classification and analyzed with McNemar’s test. We included 60 males and 20 females (median age 31 years, range 3–73). Based on PMCT, 56 (79.1%) cases had injuries relevant to the cause of death in a single body region (24 head–neck region, 32 thoracoabdominal region). Out of these 56 cases, 9 had a missed major diagnosis by PMCT outside that region, including 6 extremity injuries visible during standard external examination. Yet all had evident lethal firearm injury. We showed that PMCT identifies major firearm injuries in homicide victims and excludes injuries related to the cause of death in other regions when a single body region is injured. Although PMCT has a known limited sensitivity for soft tissue and vascular pathology, it can be combined with external examination to potentially reduce or focus dissections in some of these cases depending on the circumstances and medicolegal needs.  相似文献

Clinicians tend to overestimate their ability to recognize feigning behavior in psychiatric patients, especially if it concerns patients who have been admitted for observation. Feigning can be either externally motivated (e.g., for financial compensation, known as malingering) or internally motivated (e.g., to assume the “sick role,” known as factitious disorder). Persistent presentation of severe symptoms is usually associated with the factitious disorder. We present two patients with strong external incentives who consistently and convincingly feigned severe psychiatric symptoms during a protracted period of inpatient observation in a specialized center; both were engaged in a procedure for medical asylum. The first case presented with the clinical picture of a psychotic depression with severe motor symptoms, and the second case showed symptoms of a chronic post-traumatic stress disorder with secondary psychotic symptoms. Both cases were thoroughly investigated but feigning was overlooked, and unnecessary and harmful treatment interventions were given. To prevent iatrogenic damage, we recommend a critical attitude that takes malingering as an option into account in settings where patients are often involved in high stake legal procedures. A clinical sign that might indicate feigning is therapy-resistant symptoms. To rule out feigning a comprehensive, multimethod approach is required, but an active stance toward collateral information is essential. Specialized psychological tests may be useful for preliminary screening, but for their use in culturally diverse populations as in refugee mental health more research is needed.  相似文献

Hacking trauma is prevalent in forensic cases involving genocide and dismemberment, but research into the identification of this type of trauma is lacking. The present study examines characteristics of hacking and blunt force skeletal trauma in order to determine if there is a point at which blunt force trauma becomes distinguishable from hacking trauma. Ten implements with a range of blade angles (i.e., the striking surface of the implement) were used in conjunction with a controlled-force hacking device to impact 100 limb bones of white-tailed deer (Odocoileus virginianus). Observations of the trauma included the occurrence and degree of fragmentation, the entrance widths of the impacts, and composite scores of six hacking characteristics, especially the distinctive V-shaped kerf. ANOVA tests and regression analyses were used to assess the relationships between these characteristics and the blade angles. A significant relationship (p-value = 0.011) was found between the composite hacking scores and the blade angles, indicating that blunt force and hacking trauma can be distinguished. The entrance widths of the impacts exhibited a significant relationship with the blade angles (p-value = 0.037). There was also a significant relationship between the visibility of a V-shaped kerf in the bones (p-value = 0.003), with visibility decreasing around the 60° blade angle. These data should assist in establishing guidelines to differentiate hacking and blunt force skeletal trauma in cases where the implement is on a spectrum between sharp and blunt.  相似文献

In the last years, ageing – or rather active ageing – has become a highly popular issue. In contrast to the disputed activation in labor market policies, the activation of old age seems to be a win-win-situation that benefits everyone. However, embedded in two highly topical debates – demographic change and activation-based welfare state reform – the conditions of the popularization of active ageing remain a blank within the German discussion. This concerns the specifics of old age activation as well as the power-related implications and the normalizing and standardizing consequences of this re-negotiation of old age. It is the aim of this article to discuss these blanks theoretically, paying reference to Anglo-Saxon gerontology, to works on active society and to gender theory on sameness and difference.  相似文献
