加强职工队伍建设提高职工队伍整体素质

在全面建设小康社会过程中,必须发挥工人阶级的创造作用,同时要努力提高职工队伍的整体素质.工会要围绕提高职工思想道德素质、科学文化素质和健康素质开展工作.     

对切实发挥基层工会作用的思考

基层工会要切实发挥作用,必须建立健全基层工会组织体制;从"两项制度"入手,建立基层工会维权的监督、制约和保证机制;通过深入开展建家活动,增强基层工会的凝聚力;适应基层工会有效开展活动的需求,建立工会干部管理、保障和培训制度;同时在新形势下要加强工会理论研究和调研工作,构建基层工会工作创新机制.     

Development of a specific fragment pattern-based quadrupole-Orbitrap mass spectrometry method to screen adulterated products of phosphodiesterase-5 inhibitors and their analogues

Recently, adulterated supplements with phosphodiesterase-5 inhibitors (PDE-5i) have frequently observed. New synthetic analogues obtained from the chemical modification of parent compounds are frequently found in illicit products despite continuous efforts to inspect for these adulterants. A rapid and accurate method based on quadrupole-Orbitrap mass spectrometry was developed for simultaneously confirming and quantifying 85 PDE-5i and derived analogues present in illicit products for erectile dysfunction (ED). Common ions of PDE-5i according to their similar structures were proposed based on MS/MS fragmentations. These common ions could be an important diagnosis of their presence targets or new emerging analogues in supplements. Several validation parameters were employed, resulting in a limit of detection and quantification of 0.09–8.55 ng/mL and 0.24–17.10 ng/mL, respectively. The linear correlation coefficient (r²) was higher than 0.995, and mean recoveries of target compounds were in the range of 82–118%. A total of 187 illicit products, obtained from on/offline markets over a period of 3 years (2015–2017), were screened by the established method. Approximately 53% of them were adulterated with PDE-5i or derived analogues at concentrations of 0.1–726.0 mg/g in the illicit products. In the interests of public health, this study describes a rapid and accurate method to determine PDE-5i and new emerging analogues in adulterated products.     

Development of Latent Fingermarks on Surfaces of Food‐A More Realistic Approach

Latent fingermark developing methods from food (mandarin, egg, banana, apple, potato, carrot, eggplant, onion, bell pepper, and tomato) surface has been studied by 10 methods, including powdering method, small particle reagent method, and cyanoacrylate fuming method. The foods were stored under two conditions (room temperature and refrigerator) before fingermark deposition and aged for 2, 24, 48, and 72 h before fingermark development. In most of the food surfaces used in this study, cyanoacrylate fuming with 80% relative humidity was superior to the powder or small particle reagent methods. The quality of the fingermarks varied depending on the storage conditions before the fingermark deposition (in the refrigerator or at ambient temperature) and the time elapsed since the fingermark deposition. However, the storage conditions before the fingermark deposition and the time elapsed since the fingermark deposition did not show any correlation with the quality of the fingermark.     

后危机时代工资集体协商中的工会策略

政府主导、企业偏向的博弈政策环境导致了劳动收入份额的长期不合理下降,后危机时代中国经济增长内生动力机制的重塑诉求为扭转这一势头提供了契机。工会应抓住这一机会,利用当前与己有利的经济形势和政策倾向谋求劳动者收入的提升。为此,工会在工资集体协商中可以采取以下策略:及时调整指导思想;提高协商代表素质;提升对相关资料的分析能力;创造更好的外部环境。
