When Canadian salmon farmers find the health of their stock is compromised by infection or disease, the use of drugs or pesticides can be required. In Canada, there is a very limited range of these chemicals legally available to farmers and veterinarians. The formal approval and registration process for these chemotherapeutants is complicated. It involves the overlap of a variety of government departments, depending on the method of application of the therapeutic compound. These formal channels, through which chemotherapeutic products, specifically drugs and pesticides, are licensed for use, are both lengthy and costly to navigate. Often, these costs exceed any potential returns from the sale of the products (OCAD, 2001; Harper, 2002). Consequently, unapproved drugs, which would not normally be available for use, are obtained through alternative channels, which may pose a number of environmental, human, and animal safety concerns. This article seeks to provide a better understanding of the approval process and regulations governing drugs and pesticides and how they are made available for use in Canadian salmon culture. 相似文献

Climate change is having and will continue to have a range of negative impacts on social–environmental systems. Many ports, with their coastal locations and essential roles in regional and national economies, face particular exposure to storm impacts that may worsen with climate change. Currently in the United States port resilience planning falls primarily on port operators. Engaging a wider range of stakeholders in long-term seaport functioning may reduce risks from disruptive and potentially irreversible impacts of climate change. This study uses empirical data gathered through two case studies of highly exposed U.S. ports, Gulfport (MS) and Providence (RI), to identify strategies that port planners and external stakeholders consider feasible for enhancing their port's resilience. This article categorizes these resilience strategies and suggests the potential role that different stakeholders could play in facilitation and implementation. 相似文献

犯罪污损了刑法所保护的法益,导致某种社会关系的断裂。欲修复有序和谐的社会关系,须架构良性运行的治理模式。犯罪综合治理是我国的基本模式,但对甘青藏等民族地区的犯罪治理,在制度安排上应高度考量当地实情,遵从刑事法律谦抑原则,秉持法律多元主义立场,彰显刑事法的实质理性,改造和调适诸如刑事习惯法、乡约村规等具有"地方性知识"的解纷资源,通过适度变通刑事法律、分区治理、积极展开犯罪预防、制定并实施公平详备的社会政策以及有效整合社会资本等途径,均衡各方主体利益,形塑符合本土需求和民众认同的压力疏导型治理模式。 相似文献

维索尔伦在前人的研究基础上,对语境展开动态研究,他的语境顺应论能更好地解释新闻报道中的语境顺应性特征。本文主要借鉴Verschueren的顺应理论,从新闻报道对心理机制、社会世界和物质条件的顺应三个方面分析了新闻报道的语言顺应特征,并认为了解新闻报道的语言顺应特征,对新闻记者、读者和语言教学的教师都具有一定启示意义。 相似文献

Adverse weather conditions, congestion at airports, and mechanical failures often disrupt regular flight schedules. The irregular flight recovery problem aims to recover these schedules through reassignments of flights and cancellations. In this article, we develop the classic resource assignment model for the irregular flight recovery problem, and a new hybrid heuristic procedure based on greedy random adaptive search procedure (GRASP) and simulated annealing algorithm is presented to solve this problem. As compared with the original GRASP method, the proposed algorithm demonstrates quite a high global optimization capability. Computational experiments on large-scale problems show that the proposed procedure is able to generate feasible revised flight schedules of good quality in less than five seconds. 相似文献

Many marine protected areas (MPAs) face a multitude of threats to the ecosystems that they have been established to conserve. This study is based on 111 interviews conducted in 2013–2014 designed to discover the perceptions of stakeholders about the threats, the causes of the threats, and their responses to the threats, to a well-established MPA – Cabo de Palos - Islas Hormigas (CPH-MPA). This MPA was created to safeguard fisheries and the associated artisanal fishers, but over time it has become a tourism “hotspot.” Resilience theory, which incorporates ecological resilience, social resilience, and individual resilience, helps us to analyze stakeholders' responses to threats by categorizing them into passive, adaptive, and transformative responses. We found respondents identified four main threats – over-fishing, excessive scuba diving, pollution, and invasive species; attributed the threats to three main causes – ineffective management, poor environmental stewardship, and climate change; and expressed three kinds of responses – do nothing, adapt, or transform – with a preference for adaptation and (especially) transformation. The lesson of this study is that it shows how, unless drastic action is taken to curb recreational diving activities, the CPH-MPA is in danger of changing from a fishing reserve to a largely unregulated leisure diving venue, which is unlikely to fulfill the requirements of resilience; ecological, social, or individual. 相似文献
