劳模精神、劳动精神和工匠精神探析

党的十八大以来,在习近平总书记关于工人阶级和工会工作的系列重要讲话中,多次强调要坚 持弘扬劳模精神、劳动精神、工匠精神。认真领会劳模精神、劳动精神、工匠精神的科学内涵以及它们之间的 逻辑关系,对于实现中华民族伟大复兴的中国梦、增强文化自信和全面提升我国产业工人队伍整体素质有着重 大的理论价值和现实意义。劳模精神和劳动精神是整体和部分的关系,劳模精神和工匠精神是外力和内力的关系, 劳动精神和工匠精神是共性和个性的关系。总之,劳动精神,工匠精神,劳模精神存在逐步递进的逻辑。劳动 精神是成为人的精神,工匠精神是成为更加优秀的人的精神,劳模精神则是成为影响别人的人的精神。     

技术创新模式下的社会资本与网络关系的影响研究

近年来,我国生产性服务业正在以服务经济为主导的产业结构中快速迈进,诸多生产性服务中间投入要素也正向制造业融入,二者已进入互动发展阶段。文章立足于社会资本和社会网络关系理论,深入研究了生产性服务业与制造业在不同技术创新互动阶段下,社会资本决定的网络主体强弱关系对企业选择技术创新模式的行为影响,并结合中国塑料城塑料研究院有限公司近年来的技术创新进行了案例分析。由此获得的结论是：制造业是服务业发展的前提和基础,生产性服务业是关联制造业体系的重要补充,服务业体系的发展必然依托于制造业强有力的技术创新;互动发展中的网络主体强弱关系与技术创新模式存在一定相关性,弱关系促进探索式创新,强关系促进利用式创新;不同互动阶段,技术创新也存在不同特征,并具有协同演化趋势。     

指纹鉴定标准研究

通过对国内学术界关于指纹鉴定标准构建的几种思路的分析,经综合比较,选择符合点＂数量＂思路作进一步探讨。在简要分析国外指纹鉴定＂数量＂标准研究概况基础上,尝试提出新的＂指纹特征组合概率计算模型＂,并以概率计算方式论证了8个符合点作为鉴定标准的合理性,由此得出一些对指纹鉴定工作可能有现实意义的结论。     

Does gang membership pay? Illegal and legal earnings through emerging adulthood*

Gang membership is believed to impede success in the legitimate economic market while simultaneously supporting success in the illegal market. We extend the study of the economic effects of gang membership by using a within‐ and between‐individual analytic design, decomposing gang membership into multiple statuses (i.e., entering a gang, continuously in a gang, leaving a gang, and inactive gang membership), examining legal and illegal earnings simultaneously, and accounting for factors endogenous to gang membership that may contribute to economic achievement. By using panel data from 1,213 individuals who participated in the Pathways to Desistance Study to conduct a multilevel path analysis, we find that active gang membership status is unrelated to legal earnings. Alternatively, entering a gang is associated with increased illegal earnings, attributable to changes in delinquent peers and drug use, whereas leaving a gang has a direct relationship with decreased illegal earnings. Our results indicate that the positive economic effect of gang membership (i.e., illegal earnings and total earnings) is short‐lived and that, on balance, the sum of the gang membership experience does not “pay” in terms of overall earnings.     

Application of MALDI‐TOF MS for Estimating the Postmortem Interval in Rat Muscle Samples

Estimating the postmortem interval (PMI) is very important in the forensic sciences. Although many approaches have been used for estimating the PMI, accurate PMI calculations are still difficult. In this study, four Sprague Dawley (SD) rats were sacrificed by suffocation, and muscle samples were collected by dissection at various time intervals (0, 48, 96, and 144 h) after death. All samples were probed using matrix‐assisted laser desorption/ionization time‐of‐flight mass spectrometry (MALDI‐TOFMS) to obtain molecular images and data for principal component analysis (PCA). The results showed that the peaks at m/z 1511, 1543, 1564, 1586 clearly decreased in intensity from 0 to 144 h postmortem and that the time groups were separated from each other on the PCA score plot. The prediction model showed high recognition capability (95.93%) and cross‐validation (83.72%). Our work suggests that MALDI‐TOF MS can be used to determine the PMI.     

The Impact of Negative Publicity on Police Self-legitimacy

High-profile events involving police use of force in various cities throughout the US and internationally have garnered enormous media coverage and demonstrated the importance of police-community relations. To date little empirical attention has focused on how such events may negatively impact police officers. Using survey data from 567 officers, this study considers whether perceptions of negative publicity are adversely related to officers’ sense of self-legitimacy (i.e. the confidence they have in their authority). Findings revealed officers who felt less motivated as a result of negative publicity expressed less self-legitimacy. However, the degree to which officers felt their job had become more dangerous as a result of negative publicity was not significantly related to self-legitimacy. These findings increase our understanding of the sources of self-legitimacy and reveal that negative publicity surrounding law enforcement presents a unique challenge to officers’ confidence in their authority, which can have important implications for the community.     

The talk–listen–respond (TLR) model of representatives on Twitter

Despite the existing research on how elected representatives use Twitter, there are few comparative studies and none that considers Israel, a country that differs from most democracies in its electoral system. This study has two levels of analysis. The first is the country level, in which the author compares and explains how representatives in four countries – the US, Canada, Australia and Israel – use the talk, listen and respond model to achieve their goals. The second is the individual level, in which the author analyses how personal characteristics such as gender and age, and political characteristics such as seniority and membership in the opposition or coalition affect the frequency of use of Twitter. Using quantitative data, it is demonstrated that representatives vary in the frequency of their use of Twitter. On the country level, Australian representatives use Twitter more often than their counterparts in other countries. On the individual level, first-term members, members of the opposition, and older representatives use Twitter more often than those with more seniority, coalition members, and younger legislators.
