Effectiveness of Femur Bone Indexes to Segregate Wild from Captive Minks,Mustela vison,and Forensic Implications for Small Mammals

Utilization of free‐living populations of endangered wildlife species is usually strictly prohibited or restricted. Farming of endangered species can provide products that are in demand as a countermeasure. A novel forensic issue arises because it becomes necessary to discriminate the origin of given wildlife products. We tested the effectiveness of five measurements and four indexes of femur bone using farmed minks (n = 40) and escapees (n = 32). Results showed all measurements, namely body mass (L_f), body length (M_f), femur mass (V_f), femur length (M_b), and femur volume (L_b), were highly discriminatory. However, they are susceptible to the influence of nutrition level and sex. Femur length index (I_fl), femur linear density (D_l), and femur volume density (D_v) eliminated the influence of level of nutrition and were highly effective. However, I_fl and D_l were influenced by sex (p = 0.000). Because D_v was not influenced by sex (p = 0.683) and was highly effective, it was the preferred index.

The Role of Competition in Determining Corporate Governance Outcomes: Lessons from Australia's Corporate Governance System

Successive waves of corporate collapse in every decade of Australia's history suggest that there is a significant unresolved corporate governance problem in Australia. Corporate collapse has been followed by reform but with little effect on the overall pattern of collapse and reform every decade. This article suggests that one of the elements which entrenches corporate governance problems in Australia is the competitive environment in which companies operate, which currently is not regulating management. It is argued that this anti-competitive environment has two significant effects. First, key shareholders have retained controlling blocks of shares as the benefits of control and the costs of unconstrained management are high in such distorted markets. Secondly, management skills have stagnated, so that bad management and regular management failure have become features of the corporate governance system.     

高效液相色谱法同时检测水产品中7种四环素类抗生素残留的研究

采用Inertsil C8-3(5μm,250 mm×4.0 mm i.d.)反相色谱柱,以pH 4.0的EDTA-McIlvaine缓冲溶液为提取溶液,以HLB固相萃取柱为净化柱,以甲醇 乙腈 0.01 mol/L三氟乙酸为流动相(梯度洗脱),流速为1.5 mL/min,检测波长为350 nm,进样量100μL,建立了同时检测水产品中四环素、金霉素、土霉素、强力霉素、去甲基金霉素、甲烯土霉素和二甲胺四环素等7种四环素类抗生素残留的液相色谱法。该方法的检出限为1.5~5.0μg/kg,测定低限为50μg/kg,线性范围为50~1 000μg/kg,加标回收率为75.2%~100.6%,相对标准偏差为2.19%~10.56%。上述结果表明,该方法具有灵敏、准确、简便、快速等优点,适用于水产品中上述7种四环素类抗生素残留的同时检测。     

后配额时代中国纺织服装业应对国外反倾销法律对策探讨

Sleeping accidents in the elderly

Two cases of dangerous sleeping environments in the elderly are reported to demonstrate similarities and differences of these "sleeping accidents" to similar episodes that occur in infants and children. CASE REPORTS: An 87-year-old wheelchair-bound man with a history of dementia was found in his nursing home room hanging off the side of the bed from a vertical metal bar, and an 87-year-old woman with epilepsy, ischemic heart disease, and insulin-dependent diabetes mellitus was found in hospital wedged between an inflatable mattress and the bars of her bed. These cases demonstrate that, as in the very young, relatively poor coordination and strength in the elderly often with limited comprehension and ability to deal with dangerous environments may predispose to sleeping accidents. Significant underlying organic disease may, however, make determination of the precise lethal mechanisms difficult. Modification of beds should only be undertaken when safety issues have been carefully evaluated.
