Gender differences and the effects of perceived internet privacy on self-reports of sexual behavior and sociosexuality

The use of the Internet for conducting research has found that the level of anonymity intrinsic to web-based surveys is useful in deterring various participant biases. Though, concerns about Internet privacy could interfere with the effects of perceived anonymity and influence how a person responds. In this study, participants were asked to take an Internet survey and then were randomly assigned to conditions with varying degrees of implied privacy in which they answered questions about their desire for casual sex (sociosexuality) and their lifetime sexual partners. Only in the condition without any threat to the participant’s anonymity was there no difference between men and women’s reports of their sexual behavior. However, in every condition men reported having a significantly higher sociosexuality than women. Findings are consistent with both the biologic and gender-biased explanations in differences of self-report for sexual information. Implications for social constraints and Internet based research are discussed.     

Ontology development for run-time safety management methodology in Smart Work Environments using ambient knowledge

This paper presents the development of a decision support system for run-time safety management in Smart Work Environments (SWEs). Our approach consists of four main phases: (i) definition of the basic steps of a methodology for run-time safety management; (ii) development of an ontological knowledge-base of safety in work environments; (iii) definition of constraints on the ontology based on organizations’ safety protocols; (iv) communication of relevant information to each actor in the safety management team. We propose a generic ontological model of safety expertise, based on Occupational Safety and Health Regulations (OSHA), that is employed as Knowledge required in our safety management methodology based on the MAPE-K (Monitor–Analyze–Plan–Execute and Knowledge) loop. We present the RAMIRES (Risk-Adaptive Management in Resilient Environments with Security) tool, implementing this methodology. RAMIRES is developed as a dashboard, supporting the safety management team in understanding the risk and its consequences, and to support decision making in risk treatment. RAMIRES interacts with the SWE and the safety management team (actors) in order to: (i) communicate the risks and preventive strategies to actors; (ii) obtain more data about the observed areas to understand the risk and its consequences; and (iii) execute the automatic preventive strategies and support actors in the execution of human-operated preventive strategies. In this paper, we show the details on concepts designed in the safety ontology and illustrate how these concepts can be extended to provide an abstract model of a specific use case. Furthermore, we propose the definition of constraints on the ontology using logic-based rules. Finally, we discuss the advantages and limitations of the proposed methodology regarding the resilience of the environment.

Optimisation of one-stop delivery scheduling in online shopping based on the physical Internet

The circulation of online shopping commodities generally involves many entities, such as online manufacturers, wholesalers, retailers and customers. Goods from manufacturers to consumers undergo several exchange stages involving different economic entities. The logistics cost increases in certain supply chain nodes and the risk of backlog or running out of stock is high because of the different income and risk expectations of entities, as well as the varying degrees of information sharing between them. Clearly, a one-stop delivery mode crossing numerous transaction links in online shopping can effectively solve these problems and save social resources. However, realising this one-stop mode requires a series of specific premises, appropriate software and hardware technology support. This study introduces the Physical Internet into the one-stop delivery mode as an important logical and technical support, analyses the operating mechanism of the Physical Internet and discusses the operating conditions of one-stop delivery. It analyses the optimisation contents and objectives of one-stop delivery scheduling to construct a multi-objective optimisation mathematical model and propose a solving algorithm. Finally, this study uses an application case to verify the feasibility and effectiveness of the optimisation mechanism and algorithm.     

Integrated and Intelligent Manufacturing: Perspectives and Enablers

With ever-increasing market competition and advances in technology, more and more countries are prioritizing advanced manufacturing technology as their top priority for economic growth. Germany announced the Industry 4.0 strategy in 2013. The US government launched the Advanced Manufacturing Partnership (AMP) in 2011 and the National Network for Manufacturing Innovation (NNMI) in 2014. Most recently, the Manufacturing USA initiative was officially rolled out to further “leverage existing resources... to nurture manufacturing innovation and accelerate commercialization” by fostering close collaboration between industry, academia, and government partners. In 2015, the Chinese government officially published a 10-year plan and roadmap toward manufacturing: Made in China 2025. In all these national initiatives, the core technology development and implementation is in the area of advanced manufacturing systems. A new manufacturing paradigm is emerging, which can be characterized by two unique features: integrated manufacturing and intelligent manufacturing. This trend is in line with the progress of industrial revolutions, in which higher efficiency in production systems is being continuously pursued. To this end, 10 major technologies can be identified for the new manufacturing paradigm. This paper describes the rationales and needs for integrated and intelligent manufacturing (i²M) systems. Related technologies from different fields are also described. In particular, key technological enablers, such as the Internet of Things and Services (IoTS), cyber-physical systems (CPSs), and cloud computing are discussed. Challenges are addressed with applications that are based on commercially available platforms such as General Electric (GE)’s Predix and PTC’s ThingWorx.     

Internet use and depression among older adults

The findings regarding the impact of Internet use on well-being are mixed and studies are often criticized due to small samples and lack of consistency in measurement. Fewer studies have examined this issue among older adults. The purpose of this study is to examine the relationship between Internet use and depression among retired Americans age 50 years or older. Using data from the Health and Retirement Survey, the study estimates the relationship between Internet use and depression through combined use of regression and propensity score methodologies. All empirical methods indicate a positive contribution of Internet use to mental well-being of retired older adults (?50 years), reducing depression categorization by approximately 20–28%.     

Diffusion of innovation model of consumer behaviour - Ideas to accelerate adoption of renewable energy sources by consumer communities in India

Renewable Energy (RE) sources form a minuscule portion of India’s overall Energy consumption today. India continues to rely on fast depleting fossil fuel and expensive Oil imports to satisfy the energy demands of the economy. But this is hardly sustainable and India has to quickly get RE sources to play a major role in servicing the energy needs of its population. Despite the best efforts the adoption of RE sources by consumer communities in India is patchy. This article will focus on what needs to be done to create a pull from the market for RE sources, by looking at Consumer Behaviour literature available in the area of Diffusion of Innovation[1]. Demand for RE sources from consumer communities must reach a tipping point[4] quickly; for the sector to take-off on its own and become a self-sustaining business.     

互联网管控法律体系研究

互联网在给人们工作、生活带来快捷便利的同时，也能产生巨大的负面效应。为维护互联网健康有序和谐稳定发展局面，必须加强对互联网的依法管控。目前，我国针对互联网管控出台了一系列法律法规，多个管理部门也在依法履行管控职能，但在管控过程中还存在诸多问题，实际管控效果不尽人意。在当前互联网发展新形势下，需要分析借鉴国外先进的管控经验，从法律制订、法律遵循、法律实施等多方面去进一步健全完善我国互联网管控法律体系。     

Which developing countries have done the most to close the digital divide?

Often, an answer to the question posed in the title is provided for either mobile phones or the Internet but not both at once. In this paper by contrast I require that successful countries do well on both forms of technology, over the period from 2000 to 2006. Using two measures for both mobile phones and the Internet, countries were ranked in four tables, which served as the basis on which the major conclusions were drawn. I find that Jamaica performs much better than any other low or low-middle income country, though there is a group of four other countries in a clear secondary position. My explanations of particular outcomes were often limited by the unavailability of good country-case material (though there is some).
