Industry 4.0 technologies in the manufacturing sector: Are we sure they are all relevant for environmental performance?

This research contributes to the debate about the relevance of Industry 4.0 technologies in improving environmental performance in the manufacturing industry. We employed a qualitative–quantitative approach in which 19 Italian operations managers were interviewed and 260 managers responded to an online questionnaire. The effects of various technologies were ranked using ordinal regression. Comments and suggestions gave context to the quantitative results. Sensors, radio-frequency identification, artificial intelligence and analytics were found to be most relevant in improving environmental performance, whereas simulation software contributed moderately. Additive manufacturing, cobots, robots, automated mobile robots and automated guided vehicles had a negative effect, augmented reality had no effect and other technologies indirectly affected environmental performance. We also found a lack of knowledge and application as well as scepticism about technologies such as artificial intelligence and augmented reality. Finally, there was concern about the disposal of electrical and electronic waste produced by these technologies.

Translating sustainable and smart city strategies into performance measurement systems

This paper shows how sustainable and smart strategies can be implemented in cities and how these strategies influence, and are influenced by, performance measurement systems. Drawing upon the Foucauldian notion of governmentality, the authors present the case of Gothenburg in Sweden, where they interviewed the key actors involved in a new sustainability strategy. Translating strategy into performance measurement systems requires collaboration across organizational boundaries and considerations of financial goals and social and human aspects.     

Payments for environmental services to promote “climate‐smart agriculture”? Potential and challenges

Payments for environmental services (PES) have gained wide popularity as approaches to promote environmentally friendly land use or agricultural production practices. Yet academics have also voiced concerns against seeing PES as a panacea. This article discusses whether PES is an appropriate and promising approach to promote so‐called “climate‐smart agriculture” (CSA) practices, which we define as agricultural production practices that contribute to CO₂ emission reductions and/or removals and provide benefits to farmers via increased productivity and profits and reduced vulnerability to climate change. PES appears most promising for the promotion of CSA practices in small‐scale farming contexts with low incomes. Effective design, however, requires solid estimates of cost and benefit flows from CSA adoption over time, accounting for differences in socioeconomic and ecological conditions, and addressing the risk of leakage. Funding for such PES will likely have to come from public sources, and seems most promising where synergies with other objectives such as agricultural development, food security, and climate adaptation or other environmental services exist. The potential of alternative approaches for CSA support such as taxation with rebates for CSA practices, CSA‐related investment support such as microcredits, and hybrid approaches such as conditional microcredit should be further investigated.     

Corporate smart phones: professionals' conscious engagement in escalating work connectivity

This article explores how the adoption of company sponsored smart phones inflicts upon the lives of professionals. Drawing upon qualitative interviews at a law firm in Brazil, the experiences of new smart phone users are reported upon in detail. Increased accessibility, accuracy and speed in exchanges gave the users a sense of autonomy and flexibility. However, the technology also helped to intensify the organisation's hold on employees outside of regular working hours, reaching into new settings, time slots and social contexts. Employees expressed concerns regarding demands from superiors that negatively affected their private spheres, yet many of them paradoxically requested more efficient smart phone connectivity. The article focuses on the justifications, the different narrative strategies, employed by professionals for their conscious engagement in escalating work connectivity. It is suggested that these justifications display users' attempt to ‘dis‐identify’ with the role and practice they perform.     

采用相位判决的低复杂度广义空间调制检测算法

针对广义空间调制（GSM）系统中信号检测复杂度过高的问题，提出了一种基于相位判决的低复杂度检测算法。首先根据一种排序准则对天线组合进行排序，然后将排序后的天线组合中的符号向量依次通过基于相位判决的迫零(ZF)均衡器进行检测，最终得到星座调制符号和激活天线组合。分析和仿真结果表明，该检测算法可以有效缩小接收端的搜索范围，在提供与最大似然（ML）检测算法相近的误比特率（BER）性能的同时，计算复杂度降低了98%。

湖北省新型城镇化条件下农民收入增长研究

我国农民收入来源主要包括农业经营性收入、务工收入及其他收入。城镇化发展是农民增收的重要动力之一,十八大以来新型城镇化被提到一个新高度。新型城镇化要求把生态文明理念融入城镇化过程,实现集约、智能、绿色、低碳的发展目标。新型城镇化条件下,农民增收能否持续、高速的发展成为新的课题。文章对湖北省部分市(县)采取实地查勘、问卷调查与走访农户、搜集资料、逻辑分析的方法就湖北省新型城镇化条件下农民增收进行研究。研究结果表明:(1)新型城镇化促进农业现代化发展,提高农产品产值,减少农业产业链内耗,实现农民增收;(2)新型城镇构建农民市民化社会构架,提高了农民工资收入与社会福利收入,增加了农民收入;(3)新型城镇化改变发展模式,增加农民资产性收入与提升了农民生活品质,实现更高水平的增收。研究结论:新型城镇化是未来农民增收最主要的推动力。
