劳动力转移对城乡居民收入差距的非线性影响研究

借鉴已有相关研究成果,将劳动力转移、农业技术水平与城乡居民收入差距联系起来思考,可以具体地考察劳动力转移对城乡居民收入差距的影响.文章以农业技术水平作为门槛变量,选取2009—2019年中国31个省份的面板数据,利用泰尔指数测定城乡收入差距,以劳动力转移作为核心解释变量构建面板门槛模型,实证得出劳动力转移对城乡居民收入差距的非线性影响.研究发现:劳动力转移可以缩小城乡居民收入差距,且该影响具有单一门槛效应.在农业技术水平较低时,劳动力转移对城乡居民收入差距收敛效应较小;当农业技术水平越过门槛值达到较高水平后,劳动力转移对缩小城乡居民收入差距的效果几乎增加了一倍.此后,通过替换解释变量泰尔指数为城乡人均可支配收入比、替换核心解释变量农业技术水平为农业生产效率重新建立面板门槛模型,发现上述结论仍然成立,其检验结果具有较强的稳健性.文章将农业技术进步、劳动力转移、城乡居民收入差距这三个重要变量纳入同一模型框架中,在加深劳动力流动影响城乡居民收入差距这一视角的研究的同时,对缩小城乡居民收入差距政策的制定提供了重要的参考意义.     

核技术应用企业研发骨干激励机制探究

核技术应用一般是指射线技术与射线装置在医疗、工农业、地质调查、研究与教育中的应用。我国核技术应用企业研发骨干激励存在着激励的创新导向不足、薪酬激励机制不合理、组织文化有欠缺等问题,需结合行业特点及核技术应用企业研发骨干激励的特殊要求,采取相应的激励对策,包括从核心能力出发研究激励问题、建立适于激励研发人员的能力工资制、注重职业发展激励、注重责任激励、建立激发创新活力的组织文化等。     

科技保险的困境—一个制度供求非均衡分析

现阶段，我国步入了创新驱动引领升级的关键时期，科技创新受到了整个社会的空前重视。科技保险作为分散和转移科技风险的重要手段，可以为科技创新提供有力的风险保障。目前，我国科技保险工作已经进入全面推广阶段，虽然取得了一定的成效，但整体运行并不理想，科技企业参保率低，科技保险缺失严重。究其原因，主要在于制度供给不能适应科技企业对科技保险的需求，科技保险制度供求非均衡，在现行的科技保险制度下积聚着大量的潜在利润，而这些潜在利润既是科技保险制度非均衡的原因，又是科技保险制度创新的动力。     

浙江省城市绿色技术创新效率评价及影响因素分析

基于网络DEA模型和Malmquist指数模型，利用浙江省11个地级市的2011-2020年的数据，以降维后的污染指数为非期望产出对绿色技术创新效率进行测度和分析。发现:浙江各市总体上成果转化阶段的效率优于研发阶段，城市间发展差异较大；整体TFP指数均值为1.121，其提升主要源自技术进步；城镇化水平、产业结构优化、对外开放、政府干预和研发强度对绿色技术创新效率有促进作用，但经济发展水平与绿色技术创新效率的U型关系不显著。     

The need for knowledge modification in technology change: a framework to consider changes in domain complexity,knowledge and productivity

This paper researches productivity in relation to domain complexity and the present knowledge capacity in an organisational context. The study is based on five very different case studies. Three studies are conducted in Denmark, Germany, Mexico and China and are related to knowledge transfer in the relocation of manufacturing facilities. Two studies investigate operation and automation of oil and gas production in the North Sea. The case study method involves semi-structured interviews, surveys, an analysis of historical production data and observations. Based on the findings from the field studies, the paper develops a conceptual framework that management can use for discussions of productivity, development of knowledge and design of learning programmes when considering changes in the complexity of a domain or a change in knowledge.

“Big Brother’s Bigger Brother”: The Visual Politics of (Counter) Surveillance in Baltimore

In 2016, without the knowledge of its citizens, Baltimore City Police deployed a military aerial surveillance technology called Wide Area Motion Imagery (WAMI), which can track the movements of every person in public view over the entire city. Though the trial of the “spy plane,” as the program was dubbed, quickly ended in scandal, organizers from Baltimore’s low-income minority neighborhoods successfully rebooted the program in 2020, this time framing WAMI partly as a tool of “sousveillance” (watching “from below”) that can track the movements of police officers. The paper shows how organizers “rebranded” WAMI around two conceptions of sousveillance—“citizen-centered” and “state-centered”—creating an unlikely coalition of supporters from both pro- and anti-policing sides of the criminal justice reform debate. But while the renewed program has vowed to be a “Big Brother” to the state, it will continue to be used for traditional surveillance, raising troubling questions about privacy. The article sheds light on the politics of watching and being watched in the era of technology-driven criminal justice reform.     

Digital learning across cultures: an account of activity theory

ABSTRACT

This paper explores a teaching and learning process as it unfolds in an online offshore classroom. The paper reports on teaching and learning narratives distilled from different cultures, namely the cultures of educators and students in the context of digital learning environments. Drawing on activity theory as a conceptual framework to analyse the narrative, we employ self-study as a methodological tool for capturing the dynamism and complexities that unravel in intercultural and technology-enabled teaching activities. The framework explores the relationships, tensions and opportunities of diverse activity elements that constitute the design and delivery of digital pedagogies. In the networked intercultural system, sustaining the position of activity elements and the specific relational circuit that they institutionalise is a key task for understanding digital technologies as an influential tool for effective learning and teaching practices. We argue that seeing the digital platform from the perspective of its role in creating dynamic interrelationships in a complex activity system is one way to move beyond the cultural confines of any particular element in the system.     

Gender,technology and the ablenational Paralympic body politic

ABSTRACT

The Paralympic games is a pedagogic, pervasive, political, powerful, and ‘popular’ cultural site where the heightened visibility of disability bring into being specific forms of disability as they articulate within cultures, institutions and practices. Regarded as a ‘positive charge’ by Stuart Hall, the Paralympics intends to challenge the devalued disabled body politic of typical disability representation. This has been stimulated by the entry of Channel 4 as the UK Paralympic rights holders in 2012 which has seen greater media coverage of certain technologically enhanced cyborgian parasport bodies and an emerging celebrity / sexualized disability culture. This contemporary moment in disability representation provides a compelling space in which to (re-)address the gendered nature of hyper-visible Parasport hybrids, their potential to disrupt ‘normative’ relations of power, and, the wider impact on disability politics in a neoliberalised culture of widening and affective circuits of bodily inclusion and control. Drawing on an integrated content and textual analysis of 90?h of Paralympic programming from the Rio 2016 Games we highlight two emblematic segments so as to enhance our appreciation of contemporary disabled politics as it intersects with gender, technology and nation. We analyse these emblematic segments at the intersection of critical disability studies, cultural studies and sport, using concept of ablenationalism to highlight the extent certain technological capacitated parasport bodies perform gendered representational work as part of the seductive apparatus of neoliberal micro-governance suggestive of an emerging ecology of disability-gender relations. In doing so, we highlight the Paralympic contradictions and interrogate the assumed ‘positive charge’ of the contemporary (re-)presentation of disability.     

大数据在重大行政决策中的应用及其法治化

大数据在重大行政决策领域的应用，属于技术理性与决策规则的有机融合。凭借信息来源与技术革新，大数据可赋予传统决策向数字化转型的新动能。大数据的应用贯穿于重大行政决策始终，在市场监管、环境保护等多类事项中所发挥的实践优势较为明显，能够推动决策的高效化、提升决策的精准度、增强决策机关之间的联动。然而，大数据应用可能会引发决策安全的隐忧、个人数据存在的空间被挤压以及决策失误的责任承担等难题。对前述问题提出对策的过程，实乃数据治理向治理数据的转变，此阶段不能欠缺法律法规的引导，应尝试从决策数据安全体系的法治保障、个人数据的法律保护、决策责任追究机制的科学建构等层面去推动大数据应用的法治化。
