近年来,白及产业发展迅速,在医药、保健、美容等领域广泛应用,但是仍存在制约产业可持续发展的问题。通过对白及市场和产业发展现状进行实地调查,查阅相关文献并结合课题组研究成果,发现其主要存在以下制约因素:野生资源短缺,品种参差不齐;作用机制不明确,综合利用程度低;质量标准不明确,品质难以控制;产业层次低,产业集群发展缓慢等。因此,应通过加强白及种质资源保护和优良品种选育,深化白及作用机制和综合开发利用研究,完善白及质量评价体系,实施品牌战略,拓展销售市场等方法促进白及产业健康及可持续发展。 相似文献

ABSTRACTFood-handler hand-hygiene can be a contributory factor for food-borne illness. Cognitive data (knowledge/attitudes/self-reported practices), while informative, are not indicative of behaviour, and are subject to biases. Consequently, observation of behaviour is superior to survey data. However, researcher presence in direct observation increases reactivity, whereas video observation gives comprehensive analysis over a longer period, furthermore, familiarity reduces reactivity. Although video observation has been used to assess food safety at retail/foodservice, this valuable method is under-utilized in food-manufacturing environments. For the study, footage (24 h) was reviewed to assess compliance in a food-manufacturing site with company protocol. Video observation of food-handlers entering production (n = 674) was assessed; upon 70 occasions no attempt to implement hand-hygiene was observed. Of attempted hand-hygiene practices (n = 604), only 2% implemented compliant practices. Although 78% of attempts utilized soap, only 42% included sanitizer. Duration ranged from 1 to 69 s (Median 17 s). The study provides hand-hygiene data in an area that observational data is seldom captured. 相似文献

Patient organisations contribute to many areas of pharmaceutical policy. In developing their organisational capacity, many turn to financial support from pharmaceutical companies, which may create conflicts of interests. However, the transparency of the industry’s self-regulatory approach to the disclosure of payments to patient organisations has evaded scrutiny. Using company reports disclosing payments to UK patient organisations in 2012–2016, we evaluate the transparency of reporting using indicators derived from industry’s European patient organisation Code. We found a large proportion of companies did not have any disclosure reports available despite many having made payments, confirmed by comparing with annual financial accounts of patient organisations registered as charities. Where disclosure reports were available, many payments were not adequately described, resulting in large portions of money being disclosed without clarity as to the payment type and purpose. We found companies were clearer regarding whether payments were financial or benefits-in-kind, but transparency was particularly inadequate as to whether it could be determined if payments were indirect or direct and restricted or unrestricted, and almost no companies mentioned the VAT status of payments. Our findings suggest that the industry’s self-regulatory approach to transparency has not been working efficiently. We suggest ways for standardising and increasing the precision of information by pharmaceutical companies and advocate for the introduction of a centralised, and easily accessible national-level payment database. 相似文献

Over the last century, nutrition research and public health in New Zealand have been inspired by Dr Muriel Bell, the first and only state nutritionist. Some of her nutritional concerns remain pertinent today. However, the nutritional landscape is transforming with extraordinary changes in the production and consumption of food, increasing demand for sustainable and healthy food to meet the requirements of the growing global population and unprecedented increases in the prevalence of both malnutrition and noncommunicable diseases. New Zealand’s economy is heavily dependent on agrifoods, but there is a need to integrate interactions between nutrition and food-related disciplines to promote national food and nutrition security and to enhance health and well-being. The lack of integration between food product development and health is evident in the lack of investigation into possible pathological effects of food additives. A national coherent food strategy would ensure all components of the food system are optimised and that strategies to address the global syndemic of malnutrition and climate change are prioritised. A state nutritionist or independent national nutrition advocacy organisation would provide the channel to communicate nutrition science and compete with social media, lead education priorities and policy development, engage with the food industry, facilitate collaboration between the extraordinary range of disciplines associated with food production and optimal health and lead development of a national food strategy. 相似文献
