Social-Aware Joint Mode Selection and Link Allocation for Device-to-Device Communication Underlaying Cellular Networks

Joint mode selection and link allocation are crucial to achieve the advantage of Device-to-Device(D2 D) communications in improving spectral efficiency. In practice, cellular users tend to not be totally altruistic or absolutely selfish. How to stimulate them to devote their links and how to allocate their links to D2 D pair candidates efficiently are two main challenges. In this paper, we encourage cellular users through the variable payment with regard to the social tie strength between cellular users and D2 D pair candidates. In particular, the social tie strength is inferred through a graph inference model and its impact on the payment is quantified as a negative exponential function. Then, we propose a resource scheduling optimization model based on the non-transferable utility coalition formation game, and a distributed coalition formation algorithm based on the Pareto preference and merge-and-split rule. From them, the final coalition structure is obtained, which reflects the strategy of mode selection and link allocation. Numerical results are presented to verify the effectiveness of our proposed scheme.

From Differential Mode of Association to Tianxia Worldview:A Study on Chinese Entrepreneurial Spirit

China has made significant strides in economic and social development since reform and opening up over the past four decades.This process has been influenced by the exceptional innovation and entrepreneurship of Chinese business leaders,as well as their profound sentiments of compassion for the world and their country.It is of great significance to foster and promote an entrepreneurial spirit with distinctive Chinese characteristics.Not only is such spirit essential to the high-quality development of enterprises and the economy,but it is also a critical impetus for achieving Chinese modernization.Nevertheless,there is still a paucity of adequate theoretical discourse on the cultural origins and entrepreneurial spirit of outstanding Chinese business leaders.This paper employs the classical grounded theory method to conduct a 10-year follow-up research on 11 representative entrepreneurs and their enterprises.The results indicate that these entrepreneurs exhibit an evolving worldview along the paths of“self-cultivation and moral conduct”,“assisting employees to achieve”,“multilateral symbiosis”,and“the oneness of existence”when interacting with themselves,employees,partners,the general public,and all things in nature.Such entrepreneurial spirit is embodied in this paper as the“Tianxia(all-under-heaven)worldview”.Through theoretical construction,this study defines the concept of“Tianxia worldview”and extensively examines the distinctions and connections between the broadminded“Tianxia worldview”and the kinship-centered“differential mode of association”in terms of internal structure,value orientation,and applicable groups.It is posited that the transition from the former to the latter is a continuous process of transcendence and evolution of the individual mindset.This study has theoretical significance in the context of advancing the research on the Chinese entrepreneurial spirit,transcending the constraints of the management approach based on the“differential mode of association”,and enhancing the research on social responsibility from the perspective of“benefit corporations”.It also has practical value in overcoming the trust dilemma and development impediment of family businesses,ensuring that enterprises consciously fulfill their social responsibilities in a broader social context,and achieving common prosperity and progress for both enterprises and society.

Attention-Based Bi-LSTM Model for Arabic Depression Classification

Depression is a common mental health issue that affects a large percentage of people all around the world.Usually,people who suffer from this mood disorder have issues such as low concentration,dementia,mood swings,and even suicide.A social media platform like Twitter allows people to communicate as well as share photos and videos that reflect their moods.Therefore,the analysis of social media content provides insight into individual moods,including depression.Several studies have been conducted on depression detection in English and less in Arabic.The detection of depression from Arabic social media lags behind due the complexity of Arabic language and the lack of resources and techniques available.In this study,we performed a depression analysis on Arabic social media content to understand the feelings of the users.A bidirectional long short-term memory(Bi-LSTM)with an attention mechanism is presented to learn important hidden features for depression detection successfully.The proposed deep learning model combines an attention mechanism with a Bi-LSTM to simultaneously focus on discriminative features and learn significant word weights that contribute highly to depression detection.In order to evaluate our model,we collected a Twitter dataset of approximately 6000 tweets.The data labelling was done by manually classifying tweets as depressed or not depressed.Experimental results showed that the proposed model outperformed state-of-the-art machine learning models in detecting depression.The attention-based BiLSTM model achieved 0.83%accuracy on the depression detection task.

数字资本时代的社会时间:形成、问题与重构

数字资本生发于资本同数字技术的相互融合并成为资本的当代在场形态。数字资本通过变革劳动世界和重塑生活世界来建构新的时间结构,促使人的存在方式呈现出新变化和新特点。但同时,数字资本没有从根本上改变增殖本性和剥削关系,势必会创造操控劳动时间的新形式,以及建构消费时间和他者时间来填充、替代人的闲暇时间,引致人的生活时间转换成为契合其增殖和权力控制的时间。所以,当代男女在数字资本规划和建构的社会时间中难以真正创造美好生活,甚至会畸变成为顺从数字资本宰制的无个性存在。在数字资本显示生命力的当下,以社会主义制度为依托,规范和引导资本发展来使数字技术服务于以人为核心的社会时间建构,是人们在占有和支配自由时间中创造美好生活和创建理想生存方式的可行性道路。因此,对于数字资本同社会时间的关系展开系统把握的意义,不单单是批判性反思数字资本是怎样在规划和建构社会时间中形塑和规训人,更是为了探寻如何在克服数字资本的时间盘剥与时间操控中开创新的生活方式,促推人的全面发展。

The NDC Model:A Way to Resolve Moral Hazard in Chinas Social Security System

Since the mid-1990s, China has adopted a partially funded pension scheme in building itssocial security system. However, after nearly 10 years of operations, people found that theserious moral hazard problem of contribution defaults and loss of control concerningpension payment stemmed from this partially funded pension scheme. This institutionalarrangement has also resulted in the so-called adverse selection in non-market institutions,which in turn is capable of destroying the current system.This article argues for the introduction of the Notional Defined Contribution (NDC)scheme, because it can solve the problem of moral hazard and adverse selection. Moreover,it can solve the problem of a lack of institutional conditions for the entry of the social securityfund into the stock market. It is important to note that the NDC scheme fully conforms to theinitial intention of the policy-makers who designed the partially funded pension scheme inmid-1990s.

Impact of indoor air volume on thermal performance in social housing with mixed mode ventilation in three different climates

There are prototypes of social housing massively built in contrasting climatic conditions,generating thermal comfort needs that are difficult to satisfy by the users themselves.Variation of indoor air volume in living spaces where the use of air conditioning and natural ventilation strategies provides elements to improve thermal comfort conditions.This research shows the thermal performance located in a representative social housing according to Mexico’s National Housing Commission.Operative temperature results from a benchmark case were compared to six Virtual Evaluation Models,using the Dynamic Thermal Simulation tool Design Builder®from the perspective of probability.The main objective was to determine the minimum use of active systems with different indoor air volumes and improve comfort conditions to promote sustainable living in social housing.The analysis was conducted under an adaptive comfort range according to three different climate conditions in Mexico adopting a Numerical Theoretical Method.The main findings can be divided into two parts:a)the impact of the indoor air volume on thermal performance was evidenced in a proportion of time in three representative climates of the central region of Mexico,and b)no relationship was found between indoor air volume and thermal comfort in sub-humid cold climate;in sub-humid temperate climate,the same number of comfort hours was found in two different models,and in sub-humid warm climate,an inversely proportional relationship was found between indoor air volume and the comfort hours.This findings implies a greater knowledge relative to what we know about sub-humid cold,temperate and warm climates.

＂When I Got a Person to Communicate with, I Got a Purpose to Learn＂： Evidence for Social ＂Modes of Autonomy＇

This paper contests the notion that language learner autonomy is a monolithic construct, by offering evidence that learner autonomy （LA） is comprised of different ＂modes of autonomy＂. Thirty language learners based in Asia and the UK, completed a Q methodology card sort and were interviewed on how learning in an autonomous environment had impacted upon their development as learners. The results indicated that at least six modes of autonomy were identifiable within these language learners. Further analysis showed that social dimensions of autonomy were central to each mode, and thus reconceptualizing LA in this way allows for multiple understandings of the construct which are culturally rooted and embedded in sociocultural notions of what it means to be a language learner.

基于国际视角的工伤保险制度公平性研究

工伤保险制度作为社会保险制度的关键构成之一,可以为因工受伤的劳动者提供收入补偿。2019年社会保险费的征收主体转为税务部门,包括工伤保险在内的社会保险征管模式趋于规范,为工伤保险制度公平性奠定了一定基础。国外工伤保险制度在完善过程中积累了许多经验教训,为促进我国工伤保险征收的公平性提供参考。因此文章从工伤保险费征收的视角出发,利用国内外的政策实施效果探讨工伤保险制度和社会公平之间的关系,从征管模式、覆盖范围、筹资政策和给付形式四个方面分析工伤保险在调节公平时发挥的作用。结合中国目前工伤保险制度的优势和短板,在借鉴代表性国家如德国、法国、美国和韩国的特点和成功经验的基础上,文章总结出完善我国工伤保险制度的政策建议,明确建设社会保障征管治理现代化的总体思路,对促进收入分配公平和社会稳定发挥现实意义。

中国社会科学生产方式:来自教育财政领域的观察

本文首先提出了我国社会科学生产方式的体制学和动力学分析的概念,在此基础上提出一个“四性混合”即涵盖政治性功能、行政性治理、学术性策略和技术性条件的分析框架,继而应用此框架分析了历史上发生的3个真实研究事件——也即“4%政策目标”提出背后的研究事件、与“4%政策目标”相关的公共教育支出统计可比性研究和一个关于公共教育支出占GDP比例的国际文献综述研究——以阐明我国教育财政研究的知识生产过程的影响因素。本文最后讨论了关于中国教育财政研究的自主知识体系构建和研究范式问题的初步思考。

数字资本主义交往异化的政治经济学批判

资本逻辑与数字技术的联合进一步激化了数字资本主义社会中主体间交往的异化问题,呈现出交往主体虚拟化、交往形式碎片化以及交往关系表象化等新表现。这是资本主义生产方式将主体间的交往过程纳入资本增殖过程的现实后果,在一定程度上造成了人与人之间的交往被数据与数据之间的交往所掩盖,人在资本的宰制下进一步被工具化。对此,数字社会主义构建的数据“共享原则”为破除数字资本主义交往异化提供了一种理想范式,但其在实践层面存在着不可忽视的局限性。因此,我们仍然需要回到马克思的政治经济学原理中,探寻破除资本统治、维护数字技术良性发展、解决数字资本主义交往异化的根本性法则。

社区治理方式对居民垃圾分类行为的影响机制及分异效应

居民生活垃圾分类是生态文明建设的重要方式,也是实现碳达峰碳中和的重要途径之一。社区是推动居民垃圾分类和生活方式绿色转型的关键场域。基于“2019年上海居民垃圾分类行为”调查数据,运用结构方程模型,探究不同社区治理方式对居民垃圾分类行为的影响路径。研究发现:社会性治理方式对垃圾分类行为产生直接效应,并通过社区参与意愿、网络参与意愿对垃圾分类行为产生间接效应。房价和房龄调节了社会性治理方式对居民垃圾分类行为的影响效应,呈现了“熟人社区”“陌生人社区”和“半熟人社区”社区分异效应,形塑了“弱动员、强参与”“强动员、强参与”“强动员、弱参与”的多元主体行动逻辑。该研究能够为构建因地制宜、社区多元共建、共治、共享的垃圾分类实施政策,有效引导社区居民绿色低碳行为,促进社区生活垃圾减量化、资源化提供借鉴和政策参考。
