This study describes the performance of handheld Raman devices for determining whether suspect pharmaceutical tablets declared to contain controlled substances were consistent with authentic (CWA) or not consistent with authentic (NCWA) tablets using a simple, rapid, field-friendly method capable of being used by nonexperts. Twenty-five authentic products and 84 known NCWA tablets were examined using three “parent” devices for a total of 327 analyses. On average, the parent devices yielded a true pass rate of 100%, a true fail rate of 98.4%, a false pass rate of 1.6%, and a false fail rate of 0%. The methods/libraries were then transferred to 13 identical “daughter” devices, which were used to examine 10 suspect finished dosage forms in duplicate (six known NCWA tablets and four authentic tablets) for a total of 260 measurements. On average, the daughter devices had a true pass rate of 100%, a true fail rate of 95.5%, a false pass rate of 4.5%, and a false fail rate of 0.0%. These data demonstrate that the parent–daughter electronic transfer method was successful, which permits the ability to develop methods in the laboratory that can be seamlessly pushed out to field devices. The methods can then be used to (i) prioritize samples for additional testing using other more time-consuming laboratory-based techniques needed to detect and quantify active ingredients and (ii) help support the interdiction of dangerous tablets at ports of entry, thereby preventing them from reaching the supply chain. 相似文献

This paper analyses contrasting discourses of ‘climate-smart agriculture’ (CSA) for their implications on control over and access to changing resources in agriculture. One of the principal areas of contestation around CSA relates to equity, including who wins and who loses, who is able to participate, and whose knowledge and perspectives count in the process. Yet to date, the equity implications of CSA remain an under-researched area. We apply an equity framework centred on procedure, distribution and recognition, to four different discourses. Depending on which discourses are mobilised, the analysis helps to illuminate: (1) how CSA may transfer the burden of responsibility for climate change mitigation to marginalised producers and resource managers (distributive equity); (2) how CSA discourses generally fail to confront entrenched power relations that may constrain or block the emergence of more ‘pro-poor’ forms of agricultural development, adaptation to climate change, or carbon sequestration and storage (procedural equity); (3) how CSA discourses can have tangible implications for the bargaining power of the poorest and most vulnerable groups (recognition). The paper contributes to work showing the need for deeper acknowledgement of the political nature of the transformations necessary to address the challenges caused by a changing climate for the agricultural sector. 相似文献

- The Australian White Ribbon Day 2006 campaign was severely criticized by mental health professionals and those working in the family and domestic violence sector because of depictions of suicide and self‐harm in the television advertisement and accompanying promotional materials. The White Ribbon Day (WRD) National Leadership Group (NLG) rejected all requests by concerned groups to not use these campaign materials. They and their apologists claimed that such violent imagery was necessary to attract men's attention and was being misinterpreted as depicting suicide attempts.
- With preliminary ethics approval we set out to assess reactions to the television advertisement. After 24 interviews, the testing was terminated by the university research ethics officer after two male respondents demonstrated significant distress after viewing the ad. Furthermore, the results by that stage showed that there were perceived messages of suicide in the ad. These results were sent to the WRD NLG with a request to reconsider proceeding with the television advertisement and associated materials. Mental health and domestic violence organizations lodged similar requests. All requests were rejected. The case raises a number of ethical issues for pro‐social organizations when dealing with sensitive issues and using execution techniques that may impact negatively on vulnerable audiences.

We explore how two populations learn to cooperate with each other in the absence of institutional support. Individuals play iterated prisoner's dilemmas with the other population, but learn about successful strategies from their own population. Our agent-based evolutionary models reconfirm that cooperation can emerge rapidly as long as payoffs provide a selective advantage for nice, retaliatory strategies like tit-for-tat, although attainable levels of cooperation are limited by the persistence of nonretaliatory altruists. Learning processes that adopt the current best response strategy do well only when initial conditions are very favorable to cooperation, while more adaptive learning processes can achieve high levels of cooperation under a wider range of initial conditions. When combined with adaptive learning, populations having larger, better connected learning relationships outperform populations with smaller, less connected ones. Clustered relationships can also enhance cooperation, particularly in these smaller, less connected populations. 相似文献

This article represents the effect of public opinion on government attention in the form of an error-correction model where public opinion and policymaking attention coexist in a long-run equilibrium state that is subject to short-run corrections. The coexistence of policy-opinion responsiveness and punctuations in political attention is attributed to differences in theoretical conceptions of negative and positive feedback, differences in the use of time series and distributional methods, and differences in empirical responsiveness of government to public attention relative to responsiveness to public preferences. This analysis considers time-series data for the United Kingdom over the period between 1960 and 2001 on the content of the executive and legislative agenda presented at the start of each parliamentary session in the Queen's Speech coded according to the policy content framework of the U.S. Policy Agendas Project and a reconstituted public opinion dataset on Gallup's "most important problem" question. The results show short-run responsiveness of government attention to public opinion for macroeconomics, health, and labor and employment topics and long-run responsiveness for macroeconomics, health, labor and employment, education, law and order, housing, and defense . 相似文献

Critics of consociational power-sharing institutional arrangements in deeply divided societies argue that such arrangements solidify the underlying conflict cleavage and render it all-important for party competition and voter behaviour. I find evidence to the contrary in the case of voter behaviour at the historic 2007 Assembly election in Northern Ireland. At least in the unionist bloc, I find the effective disappearance of the ethno-national conflict cleavage as a determinant of voter choice. This suggests that consociational arrangements have led to both inclusion and moderation, rather than polarisation and ‘ethnic outbidding’. 相似文献
