The analysis of gamma-hydroxybutyric acid (GHB) is problematic because it is hygroscopic, it lacks a good UV chromophore, and it undergoes heat-induced cyclization. This paper presents a new method utilizing ion-exchange chromatography (IC) with conductivity detection. The simple sample preparation, rapid analysis time, and inorganic anion detection capabilities are all advantages over the current methods. The detection of inorganic salts (formed during GHB synthesis) gives insight into the synthetic route utilized and can aid in drug seizure comparison. The developed method has a detection limit for GHB anions of 0.57 mg/L and chloride of 0.22 mg/L. A comparison of this technique with a current gas chromatography-mass spectrometry technique is presented, and a t-test found that the two methods' results are not statistically different at the 99.9% confidence level demonstrating the merits of this fast, simple, and informative IC method as a routine screening tool. 相似文献

正On my Chinese language learning journey,I have encountered several invaluable teachers. When I first started learning Mandarin in my native United States, I took classes at an international language center near my home.My first teacher was Fiona, an immigrant from China’s Taiwan. Fiona made it her mission to fine-tune our ears to the phonetic pitfalls of Chinese. She had a beautiful soprano voice and taught us the Chinese phonetic alphabet song.The sheet music to the song had a cartoon of a little horse clutching a microphone and singing karaoke. 相似文献

Abstract It is generally assumed that empathy acts to disinhibit behaviour that could be perceived as detrimental to others, and as a result is a common feature of offender treatment programmes. The present research hypothesised that empathy in all populations is both a situational and a selective process that is ultimately governed by self-interest, and further, that it is the nature of the self-interest that distinguishes individuals rather than a general empathy deficit per se. Empathic processes were observed in a non-offending population in a personal situation normally regarded as evocative of empathy: infidelity. Thematic analysis of data from individuals who reported being faithful or unfaithful to their partners revealed five dominant themes: vulnerable predisposition, emotional motivators, rational emotive decision making, avoiding cognitive dissonance and lack of remorse. The themes all revealed how individuals employed cognitive strategies, which were managed by self-interest that functioned to create cognitive states devoid of empathy. 相似文献

The stability of two benzisoxazole antipsychotics was determined in vitro in decomposing porcine blood inoculated with bacteria, utilizing a high‐performance liquid chromatography with ultraviolet and fluorescence detection method for drug quantitation. Stability experiments for risperidone and paliperidone were conducted at 7, 20 and 37°C for 4 days using sterile and bacterially inoculated porcine blood. The drugs were stable in sterile blood at each temperature and in inoculated blood at 7°C, but degraded significantly in inoculated blood at 20 and 37°C. Complete loss occurred within 2 days when incubated at 37°C. The benzisoxazole‐cleaved degradation products for both drugs were identified as 2‐hydroxybenzoyl‐risperidone and 2‐hydroxybenzoyl‐paliperidone utilizing liquid chromatography quadrupole‐time‐of‐flight mass spectrometry and accurate mass measurements. The degradation products have been found in postmortem case studies, including one case where risperidone and paliperidone were not detected, indicating complete conversion can occur in situ. 相似文献

This article integrates the research evidence that applies Miles and Snow's strategic management framework to the performance of public agencies. Miles and Snow developed several strategy types, arguing that prospectors (searching for new approaches) and defenders (sticking with the existing pattern of services) are aligned with processes, structures, and the environment in ways that lead them to outperform reactors (awaiting for instructions from the environment), which have no consistent strategy or alignment. Six key lessons for the practice of strategic management in public organizations are provided based on a critical review. Findings point toward the importance of employing a mix of strategies in public organizations, contrary to Miles and Snow—a strong evidence base for the association between prospecting and defending and performance and for relationships between strategy types and processes and structures. However, no empirical evidence is provided for alignment across strategy, structure, process, and the environment. The findings, largely derived from the United Kingdom and United States, suggest that the most successful strategy recipe depends on the ingredients, and thus managers must pay attention to the connections between the outlined contingencies to generate the best results using the adopted strategy. 相似文献

In July 2012, the Australian government instituted the Clean Energy Legislative Package. This policy, commonly known as the carbon policy or carbon tax, holds industries responsible for emissions they release through a carbon price. Because this will have an indirect effect on consumer costs, the policy also includes a compensation package for households indirectly impacted. This study, building upon past work in distributive justice, examines the determinants of the policy’s acceptance and support. We proposed perceived fairness and effectiveness of the policy, and endorsement of free-market ideology, would directly predict policy acceptance. We tested this through an on-line survey of Australian citizens and found that policy acceptance was predicted by perceived fairness and effectiveness. More Australians found the policy acceptable (43 %) than unacceptable (36 %), and many found it neither acceptable nor unacceptable (21 %). In contrast, when asked about support, more Australians tended not to support the policy (53 %) than support it (47 %). Support was predicted by main effects for perceived fairness, effectiveness, free-market ideology, and the interaction between free-market ideology and effectiveness. We conclude by considering some of the implications of our results for the implementation of policies addressing climate change mitigation and adaptation, for theories of social justice and attitudinal ambivalence, and for the continuing integration of research between economics and psychology. Furthermore, we argue for the distinction between policy support and acceptance and discourage the interchangeable use of these terms. 相似文献
