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.     

Towards a Smart Tourism Business Ecosystem based on Industrial Heritage: research perspectives from the mining region of Rio Tinto,Spain

The implications of the study provide suggestions for future improvements relating to the development of industrial tourism destinations. The possibility of ‘re-using’ the old industrial and mining heritage could favour the development of an economic opportunity to the recession that affected most industrial regions after the 1960s. This paper is focused on the field of industrial heritage tourism management (IHTM) to deepen the knowledge about its business ecosystem. The IHTM is chosen because a number of evidences highlight the interconnections that exist between this field and the business ecosystem concept. To explore these interconnections, the purpose of this article is to define a frame of analysis based also on the emergent initiative of smart tourism and to set up a theoretical framework not only used to the case study of the region of Rio Tinto mine in Spain, but also used as a policy instrument to suggest propositions for recommending new paths for future studies.     

Effectiveness of sequences of classroom training for welfare recipients: what works best in West Germany?

Sequences of active labour market programmes (ALMPs) may be part of an intensified activation strategy targeting hard-to-place unemployed individuals. Such sequences are very common among welfare recipients in Germany, but most studies only evaluate either single ALMPs or unemployed individuals’ first ALMP. I analyse the effects of different sequences of classroom training for West German men and women on different labour market outcomes. Using rich administrative data and a dynamic causal model, I can control for dynamic selection problems that occur during a sequence. The results show that two classroom trainings are more effective than two periods of welfare receipt in helping welfare recipients find regular employment, especially among West German women. Moreover, immediately assigning individuals to classroom training is more effective than waiting and assigning them to classroom training in the second period. However, in some cases, avoiding participation in multiple programmes is preferable.

Impact of privacy concerns on resistance to smart services: does the ‘Big Brother effect’ matter?

ABSTRACT

The aim of this study is to provide a better understanding of the factors that explain consumer resistance to smart services from a privacy perspective. To this end, an exploratory qualitative study and a quantitative study were carried out. 653 French consumers answered an online questionnaire regarding smart services in the banking sector. Structural equation modelling was used to test the conceptual model. The findings show that information privacy, the unauthorised secondary use of personal information and perceived intrusion have an impact on consumer resistance to smart services. Moreover, our research highlights the major role of the ‘Big Brother effect’ as an antecedent to these various privacy concerns.     

A dynamic semester-long social dilemma game for economic and interdisciplinary courses

The authors present a semester-long game to teach the role of economics in natural resources management. The game is framed within a fisheries context: multiple student fisheries harvest fish to maximize yield/profit, which is measured using a piecewise linear function. There are prizes for both the student and the group with the highest semester-long catch, which brings forth the social dilemma associated with dynamic stock externalities in fisheries. The game can be played in large classes, is robust to student attrition, and requires 5–10?minutes per class period. Given its features, it can be used to teach behavioral economic principles in resource management, incentives versus command-and-control regulations, role of cheap talk, social preferences, punishment, and community management as well as solutions such as aquaculture.     

改革开放以来我国卫生医疗服务系统的进步与不足——基于2019新型冠状病毒与非典病毒的疫情与防控的比较分析

改革开放40年,随着我国经济的腾飞,医疗卫生体制改革也不断深化。通过比较分析我国40年的医疗卫生体制改革历程、期间的卫生医疗服务系统建设情况以及2019新型冠状病毒与2003年非典病毒的疫情及其防控情况,发现2003年的非典事件是医疗卫生体制改革的转折点,此后我国全方位的加大了医疗改革的力度并取得了斐然的成果。然而在此次新型冠状病毒防控过程依然暴露出一些问题,而这些问题正是我国正在建设的智慧医疗服务与管理所要解决的也是所能解决的重点。与时俱进的医疗卫生体制改革将为实现中华民族的伟大复兴奠定坚实的基础。

Toward an ontology‐driven blockchain design for supply‐chain provenance

An interesting research problem in our age of Big Data is that of determining provenance. Granular evaluation of provenance of physical goods (e.g., tracking ingredients of a pharmaceutical or demonstrating authenticity of luxury goods) has often not been possible with today's items that are produced and transported in complex, interorganizational, often internationally spanning supply chains. Recent adoptions of the Internet of Things and blockchain technologies give promise at better supply‐chain provenance. We are particularly interested in the blockchain, as many favored use cases of blockchain are for provenance tracking. We are also interested in applying ontologies, as there has been some work done on knowledge provenance, traceability, and food provenance using ontologies. In this paper, we make a case for why ontologies can contribute to blockchain design. To support this case, we analyze a traceability ontology and translate some of its representations to smart contracts that execute a provenance trace and enforce traceability constraints on the Ethereum blockchain platform.
