Indigenous vegetables play an important role in Kenyan food security, but production is limited by poor seed quality. Traditionally, seeds have been traded through informal networks, but a new formal seed sector is emerging. This study assessed the relative potential for formal or informal seed systems to meet the need for high-quality indigenous vegetable seed. By evaluating determinants of farmers’ seed purchasing behaviour, we conclude that informal seed systems have greater potential to meet this need and should be strengthened. This study suggests that policy-makers should use context-specific data to guide decisions on seed policy.  相似文献

Can formally employing service-users in co-production roles redress the problematic power imbalances inhibiting co-production in the public sector? In this paper, we analyze service-users formally employed in co-production roles. Through semi-structured interviews, we illustrate how actors use their voice, experience, and identity to respond to different power imbalances. First, through the process of “inverting professionalism” structural limitations resulted in neutralized co-production. Second, through the process of “embedding expertise” formally employed service-users challenged collective expectations of their role and meditated power imbalances, resulting in enhanced co-production. Finally, through the process of “perpetuating rejection” a new exacerbated power imbalance emerged when their employment became a negative resource, resulting in tokenistic co-production. We extend understandings of how formally employing service-users has potential to redress power imbalances. However, we caution against policy taking this for granted and argue that more consideration of the influence of different forms of power is needed.  相似文献

This article describes the author's experiences as a wartime cryptanalyst in two, then separate, sections of the British capability, namely that located at Bletchley Park and that at Berkeley Street in London. After recruitment and training, he worked first on the German high command teleprinter network and secondly on the Russian Comintern network which started up again in 1943. The implication is that the Cold War commenced rather sooner than was generally recognised. After the lapse of more than half a century these reminiscences are necessarily impressionistic and do not go into detail about technical methods or indeed the content of the decrypts.  相似文献

The purpose of this paper is to review the notion of branding and evaluate its applicability to political parties. As ideological politics is in decline, branding may provide a consistent narrative where voters feel a sense of warmth and belonging. The paper aims to build an understanding of the complexity of building a political brand where a combination of image, logo, leadership, and values can all contribute to a compelling brand narrative. It investigates how competing positive and negative messages attempt to build and distort the brand identity. A critical review of branding, relationship marketing, and political science literature articulates the conceptual development of branding and its applicability to political parties. The success or failure of negative campaigning is due to the authenticity of a political party's brand values—creating a coherent brand story—if there is no distance between the brand values articulated by the political party and the values their community perceives then this creates an “authentic” brand. However, if there is a gap this paper illustrates how negative campaigning can be used to build a “doppelgänger brand,” which undermines the credibility of the authentic political brand. The paper argues that political parties need to understand how brand stories are developed but also how they can be used to protect against negative advertising. This has implications for political marketing strategists and political parties. This paper draws together branding theory and relationship marketing and incorporates them into a framework that makes a contribution to the political marketing literature.  相似文献

Little is known about the amendment of death certificates (DCs) issued by medical examiners and coroners. This retrospective study examined why, how, and with what frequency cause and manner of death were amended on DCs issued by forensic pathologists over a 6-year period at the New Mexico Office of the Medical Investigator. Approximately 1% of DCs had either cause or manner of death amendments, with arteriosclerotic cardiovascular disease and intoxicants the most commonly amended and resulting causes of death, respectively. There was a significant association between manner of death and number of DCs amended (p<0.001). By percent, natural and suicide DCs were the most frequently amended. The way in which manner of death changed was significantly associated with the amount of time elapsed between DCs (p=0.04). Toxicology was the most common reason for DC amendment.  相似文献

Chronic factitious disorder with physical symptoms, or Munchausen syndrome, is a well-recognized but uncommonly diagnosed psychiatric condition characterized by the deliberate production of signs and symptoms of disease in order to receive medical attention. Clinical suspicion of this disease is rarely confirmed by autopsy, as the patients usually do not die as a consequence of feigning illness. Here we report the autopsy confirmation of a case of a suspected Munchausen syndrome patient who presented with a history of cystic fibrosis. Examination of the lungs demonstrated extensive severe interstitial fibrosis, and polariscopic examination revealed a large quantity of crystalline material throughout the tissue; X-ray diffraction identified the material as talc. Synopses of published cases of Munchausen syndrome presenting as cystic fibrosis, and cases of Munchausen syndrome with pulmonary talcosis are presented as part of the discussion.  相似文献

The Common European Security and Defence Policy (CESDP) of the European Union (EU) was launched in 1999 and has been perceived as a landmark step toward European security cooperation, particularly in the field of crisis management. Still in its early stages, some difficult issues have become apparent. Of these, the so‐called ‘third‐country’ issue may prove to be among the most significant. This problem refers to the necessity of associating states outside the EU with CESDP. In this regard, three states stand out — the United States, Turkey and Russia — and this article considers their concerns and the European response in detail. This is prefaced by a general overview of how the third‐country problem emerged and what the EU has done to address it. It concludes by suggesting that third‐country considerations could well determine where and how EU‐led missions operating under the auspices of CESDP are deployed.  相似文献

The main objective of the study was to determine the type of macroscopic trauma created by a flat-tipped and a cross-tipped screwdriver. The second objective was to determine if the trauma inflicted by the two screwdrivers could be macroscopically differentiated. Three tests were conducted, each by a male volunteer. Each test consisted of 12 samples of fleshed pig ribs; six were stabbed with a flat-tipped screwdriver and the remaining six with a cross-tipped screwdriver (Phillips). Each sample received 15 stab wounds during the process. The stabbings were conducted at perpendicular and oblique angles, with fabric variables being utilized. Results illustrate two main categories of macroscopic skeletal trauma, fractures, and puncture wounds. By studying the macroscopic appearance in tandem with differing trauma frequencies, these two screwdriver types can be differentiated.  相似文献
