SmartRolling: A human–machine interface for wheelchair control using EEG and smart sensing techniques     

《Information processing & management》2023,60(3):103262

Smart wheelchairs based on brain–computer interface (BCI) have been widely utilized recently to address certain mobility problems for people with disability. In this paper, we present SmartRolling, an intuitive human–machine interaction approach for the direct control of robotic wheelchair that jointly leverages EEG signals and motion sensing techniques. Specifically, SmartRolling offers two wheelchair-actuation modes for users with different physical conditions: (1) head motion only — people who are severely disabled but able to do basic tasks using eyes and head, and (2) head and hands motion — in addition to type 1, people who can use functioning hands/arms for extra tasks. The system issues operation commands by recognizing different EEG patterns elicited by motor execution (ME) tasks including eye blink, jaw clench, and fist open/close, while at the same time estimates users’ steering intentions based on their facing direction by leveraging inertial measurements and computer vision techniques. The experiment results demonstrate that the proposed system is robust and effective to meets the individual’s needs and has great potential to promote better health.  相似文献   

Smart cities: Advances in research—An information systems perspective     

《International Journal of Information Management》2019

Smart cities employ information and communication technologies to improve: the quality of life for its citizens, the local economy, transport, traffic management, environment, and interaction with government. Due to the relevance of smart cities (also referred using other related terms such as Digital City, Information City, Intelligent City, Knowledge-based City, Ubiquitous City, Wired City) to various stakeholders and the benefits and challenges associated with its implementation, the concept of smart cities has attracted significant attention from researchers within multiple fields, including information systems. This study provides a valuable synthesis of the relevant literature by analysing and discussing the key findings from existing research on issues related to smart cities from an Information Systems perspective. The research analysed and discussed in this study focuses on number of aspects of smart cities: smart mobility, smart living, smart environment, smart citizens, smart government, and smart architecture as well as related technologies and concepts. The discussion also focusses on the alignment of smart cities with the UN sustainable development goals. This comprehensive review offers critical insight to the key underlying research themes within smart cities, highlighting the limitations of current developments and potential future directions.  相似文献   

Intermediation in public procurement of innovation: How Amsterdam’s startup-in-residence programme connects startups to urban challenges     

《Research Policy》2019,48(9):103789

This paper analyses Amsterdam’s Startup-in-Residence (SiR) programme as new type of policy to engage startups in the development of urban innovation through a challenge-based public procurement of innovation (PPI) process. The programme is being mimicked by other cities and government agencies, but so far there has not been a rigorous, theoretically-informed analysis of the approach. In this paper, we specify and focus on the role of city-based, public-affiliated intermediaries as initiators, moderators and influencers of conversations between startups and the local government. The main contribution of SiR as a PPI intermediation programme has been to launch new types of fruitful conversations on several levels, that lead to institutional innovations rather than direct solutions for urban problems or startup development. In this sense, SiR fulfils a role inquiring and ascribing urban challenges with values and notions of “worth” that preceded and shaped innovation directions. We also suggest that engaging startups is effective for only a limited bandwidth urban challenges; different types of intermediation are required to foster collaborative innovation in more complex settings.  相似文献   

Child safeguarding practices in light of the Deserving/Undeserving paradigm: A historical & contemporary analysis     

《Child abuse & neglect》2019

BackgroundContemporary child protection systems in the UK need to be seen in light of the late nineteenth century child rescue movement, at a time of curbs in public spending, shifts in attitudes towards children’s welfare and the development of social work. There are similarities in the social, institutional and legal contexts, between the nineteenth century and today, centralising ‘deservedness’, that determined and determines children’s access to services.ObjectiveThe current article compares historical data and practices of children in care in the UK, encompassing 1881–1918, with contemporary data and practices, through the lens of the deserving/undeserving paradigm, inherited from the Poor Law of 1834.Participants and SettingDrawing on two data sets, namely historic children’s case files (N = 108), 1881–1918 from the Children’s Society (a philanthropic institution) highlighting the perception of custodians, doctors, professionals, as well as children and parents, and current data from interviews with young care leavers and safeguarding practitioners (N = 42), our research focuses on the most disadvantaged children with complex needs and damaging (pre)care experiences.MethodsData is analysed using thematic content analysis, framed within critical realist ontology, taking account of stratified non-linear dynamics of processes at different levels.Results and ConclusionIn both data sets the inability to support certain children is justified by referring to their complex needs and mental health and behavioural problems., Here, the child is held accountable and placed in the ‘undeserving’ category and consequently misses out on help and support, highlighting a need for awareness, and reflective and reflexive practice among practitioners/professionals.  相似文献   

Committee standards battles in the era of convergence: Implications for smart systems     

《International Journal of Information Management》2021

By now, there have been many standards battles fought within the same industry or by multiple industries in the market-based standardization. In these battles, incompatible standards compete to win market dominance. While there is some research on standards battles found within a single committee, competitions in the committee-based standardization between standards from different committees or SDOs are underexplored. This paper categorizes the types of standards battles by the mode of standardization and the heterogeneity of actors. A new type referred to as ‘committee standards battles for converging systems’ is introduced and the dynamics of such battles is explored with two cases. The battle between the electric vehicle charging and the smart meter communication standard and the battle between two different vehicle-to-everything (V2X) communication standards are analyzed. The failure in achieving compatibility between different committee standards on the same frequency bands results in communication interference that adversely affects the operation of smart systems. Social incompatibilities between actors and alliances from a mix of industries with vested interests towards a particular standard complicate the battling scene. The findings provide implications in terms of heterogeneity, actors, and government role in standards battles.  相似文献   

Machine learning based system for managing energy efficiency of public sector as an approach towards smart cities     

《International Journal of Information Management》2021

Energy efficiency of public sector is an important issue in the context of smart cities due to the fact that buildings are the largest energy consumers, especially public buildings such as educational, health, government and other public institutions that have a large usage frequency. However, recent developments of machine learning within Big Data environment have not been exploited enough in this domain. This paper aims to answer the question of how to incorporate Big Data platform and machine learning into an intelligent system for managing energy efficiency of public sector as a substantial part of the smart city concept. Deep neural networks, Rpart regression tree and Random forest with variable reduction procedures were used to create prediction models of specific energy consumption of Croatian public sector buildings. The most accurate model was produced by Random forest method, and a comparison of important predictors extracted by all three methods has been conducted. The models could be implemented in the suggested intelligent system named MERIDA which integrates Big Data collection and predictive models of energy consumption for each energy source in public buildings, and enables their synergy into a managing platform for improving energy efficiency of the public sector within Big Data environment. The paper also discusses technological requirements for developing such a platform that could be used by public administration to plan reconstruction measures of public buildings, to reduce energy consumption and cost, as well as to connect such smart public buildings as part of smart cities. Such digital transformation of energy management can increase energy efficiency of public administration, its higher quality of service and healthier environment.  相似文献

体育赛事转播权的多重解读及其类型化保护     

龚韬  刘智瑜  何炼红 《武汉体育学院学报》2019,53(11):43-48

体育赛事转播权是一种新兴的复合型权利，是指电视台、视频网站、直播平台等转播机构就其制作的体育赛事节目和提供的转播信号享有的著作权或者录音录像制品权、广播组织权，同时也是指赛事组织者就体育赛事享有的"转播许可权"。对其不同层次的内容应当分别予以解读，而不宜笼统地在"体育赛事转播权"这一概念下进行讨论。对赛事组织者的权利保护，有赖于体育法对其权利予以法定化；对相应的著作权人和邻接权人的保护，需要在完善著作权法的基础上，坚持作品独创性判断标准，并提升邻接权的保护水平。  相似文献   

困境与出路：我国性侵运动员犯罪行为的刑事规制探究          下载免费PDF全文

王桢 《河北体育学院学报》2019,33(1):19-27

近年来，性侵运动员的犯罪行为频发，成为国际社会聚焦的热点。以此审视我国运动员性法益的保护，虽有强奸罪、强制猥亵罪的刑事立法，却缺乏对该犯罪行为特殊性的深入思考，既不能在惩治犯罪人方面达到理想效果，亦不能在预防犯罪方面发挥良好功能。同时，司法中的“以纪代法”、针对性缺乏、未回应被害人需求等诸多问题，亦使该犯罪行为的刑事规制效果大打折扣。所以，在该犯罪立法上应有针对性采用附属刑法进行修正，完善犯罪的特别预防与一般预防制度；司法上，积极回应被害人的诉求，努力克服刑事规制过程中的各种困境，让运动员的性法益得到全面而充分的保护。  相似文献
