Adaptive structure concept factorization for multiview clustering

Most existing multiview clustering methods require that graph matrices in different views are computed beforehand and that each graph is obtained independently. However, this requirement ignores the correlation between multiple views. In this letter, we tackle the problem of multiview clustering by jointly optimizing the graph matrix to make full use of the data correlation between views. With the interview correlation, a concept factorization–based multiview clustering method is developed for data integration, and the adaptive method correlates the affinity weights of all views. This method differs from nonnegative matrix factorization–based clustering methods in that it can be applicable to data sets containing negative values. Experiments are conducted to demonstrate the effectiveness of the proposed method in comparison with state-of-the-art approaches in terms of accuracy, normalized mutual information, and purity

Volunteer Tourism, an ambiguous phenomenon: An analysis of the demand and supply for the volunteer tourism market

One of the more recent forms of tourism to emerge from the continuing fragmentation of tourism into many different forms is what has become known as Volunteer Tourism. Although itself taking on a number of variations, it is essentially the practice of individuals going on a working holiday and volunteering their labour for worthy causes. The concept of volunteer work has existed for several decades since its origins immediately following the First World War, but the idea of combining this activity with tourism is relatively new and has already changed considerably over a very short period. This thesis reviews the process by which volunteer tourism has developed, focusing on its transformation from an individual altruistic endeavour to a more commercial form of conventional tourism. As such, volunteer tourism has mirrored in many ways the development and commercialisation of opportunities for individuals to engage in ecotourism, another form of tourism which also began on a small scale with compassionate and non-economic priorities. This thesis provides a twin pronged approach to the study of volunteer tourism focusing both on the demand and the supply of volunteer tourism. The demand is investigated through an observation of a group of volunteer tourists in Mexico over a three week period and a new conceptualization of participation in volunteer tourism as a balancing act between commitment and hedonistic pursuits is developed. This thesis also reviews the growth in number of websites devoted to the various forms of volunteer tourism that now exist, and discusses the changes that have taken place in the content and focus of these websites and the organisations they represent over the last two decades. In relation to this analysis, it also examines the location of destinations which are being made available to volunteer tourists and providing the opportunity to engage in this activity. As a part of this analysis, the thesis examines the changes in the distribution of these locations and the relationship between location and the relative need of the respective destinations for assistance. The current distribution pattern of volunteer tourist opportunities now bears little similarity to the acute need for assistance that one might expect if the real motivation for providing this assistance was altruistic rather than commercial. In proposing a new approach of viewing volunteer tourism participation as a balancing act, but also by showing that the organizations involved vary in terms of their commitment and expectations, this study presents clarification on the role, expectations and motivations of the main players in volunteer tourism

State of the art of audio- and video based solutions for AAL

Working Group 3. Audio- and Video-based AAL ApplicationsIt is a matter of fact that Europe is facing more and more crucial challenges regarding health and social care due to the demographic change and the current economic context. The recent COVID-19 pandemic has stressed this situation even further, thus highlighting the need for taking action. Active and Assisted Living (AAL) technologies come as a viable approach to help facing these challenges, thanks to the high potential they have in enabling remote care and support. Broadly speaking, AAL can be referred to as the use of innovative and advanced Information and Communication Technologies to create supportive, inclusive and empowering applications and environments that enable older, impaired or frail people to live independently and stay active longer in society. AAL capitalizes on the growing pervasiveness and effectiveness of sensing and computing facilities to supply the persons in need with smart assistance, by responding to their necessities of autonomy, independence, comfort, security and safety. The application scenarios addressed by AAL are complex, due to the inherent heterogeneity of the end-user population, their living arrangements, and their physical conditions or impairment. Despite aiming at diverse goals, AAL systems should share some common characteristics. They are designed to provide support in daily life in an invisible, unobtrusive and user-friendly manner. Moreover, they are conceived to be intelligent, to be able to learn and adapt to the requirements and requests of the assisted people, and to synchronise with their specific needs. Nevertheless, to ensure the uptake of AAL in society, potential users must be willing to use AAL applications and to integrate them in their daily environments and lives. In this respect, video- and audio-based AAL applications have several advantages, in terms of unobtrusiveness and information richness. Indeed, cameras and microphones are far less obtrusive with respect to the hindrance other wearable sensors may cause to one’s activities. In addition, a single camera placed in a room can record most of the activities performed in the room, thus replacing many other non-visual sensors. Currently, video-based applications are effective in recognising and monitoring the activities, the movements, and the overall conditions of the assisted individuals as well as to assess their vital parameters (e.g., heart rate, respiratory rate). Similarly, audio sensors have the potential to become one of the most important modalities for interaction with AAL systems, as they can have a large range of sensing, do not require physical presence at a particular location and are physically intangible. Moreover, relevant information about individuals’ activities and health status can derive from processing audio signals (e.g., speech recordings). Nevertheless, as the other side of the coin, cameras and microphones are often perceived as the most intrusive technologies from the viewpoint of the privacy of the monitored individuals. This is due to the richness of the information these technologies convey and the intimate setting where they may be deployed. Solutions able to ensure privacy preservation by context and by design, as well as to ensure high legal and ethical standards are in high demand. After the review of the current state of play and the discussion in GoodBrother, we may claim that the first solutions in this direction are starting to appear in the literature. A multidisciplinary 4 debate among experts and stakeholders is paving the way towards AAL ensuring ergonomics, usability, acceptance and privacy preservation. The DIANA, PAAL, and VisuAAL projects are examples of this fresh approach. This report provides the reader with a review of the most recent advances in audio- and video-based monitoring technologies for AAL. It has been drafted as a collective effort of WG3 to supply an introduction to AAL, its evolution over time and its main functional and technological underpinnings. In this respect, the report contributes to the field with the outline of a new generation of ethical-aware AAL technologies and a proposal for a novel comprehensive taxonomy of AAL systems and applications. Moreover, the report allows non-technical readers to gather an overview of the main components of an AAL system and how these function and interact with the end-users. The report illustrates the state of the art of the most successful AAL applications and functions based on audio and video data, namely (i) lifelogging and self-monitoring, (ii) remote monitoring of vital signs, (iii) emotional state recognition, (iv) food intake monitoring, activity and behaviour recognition, (v) activity and personal assistance, (vi) gesture recognition, (vii) fall detection and prevention, (viii) mobility assessment and frailty recognition, and (ix) cognitive and motor rehabilitation. For these application scenarios, the report illustrates the state of play in terms of scientific advances, available products and research project. The open challenges are also highlighted. The report ends with an overview of the challenges, the hindrances and the opportunities posed by the uptake in real world settings of AAL technologies. In this respect, the report illustrates the current procedural and technological approaches to cope with acceptability, usability and trust in the AAL technology, by surveying strategies and approaches to co-design, to privacy preservation in video and audio data, to transparency and explainability in data processing, and to data transmission and communication. User acceptance and ethical considerations are also debated. Finally, the potentials coming from the silver economy are overviewed.publishedVersio

A critical institutionalist analysis of youth participation in Jordan's spatial planning the case of Amman 2025

By 2050, it is estimated that 84% of the population in the Global South will be living in urban areas. As a country of the Global South, Jordan has experienced dramatic growth of urban areas over the past decades. Cities in Jordan contain 83% of the population, of which, it is estimated, 24% are in the age group 15–24. Youth input, effort and experience in the planning process are recognised by academic research and international aid donors as a significant element in catalysing positive social and economic change and ensuring sustainable development across the Global South. Consequently, this research aims to investigate whether young groups’ vision and aspirations for, and perspectives on the city of Amman were translated into strategies or projects in urban policy. In doing so, it aims to explore the wide range of institutional challenges and opportunities that either hinder or encourage youth participation in policymaking. To achieve this aim, this study followed the inductive–deductive cycle of knowledge. This research starts with a critical literature review of theories in planning, governance, youth participation and spatial planning in Jordan. Healey’s systemic institutional design for collaborative planning was employed to critically analyse the planning system (hard infrastructure) and planning practice (soft infrastructure) within the chosen case study of Amman 2025. Amman 2025 is a significant and unique strategic spatial planning project in Jordan designed to encourage public participation in the policymaking process regarding urban development in Amman. New primary data were collected through extensive qualitative research in the form of semi-structured interviews and focus groups to cover the period from the start of Amman 2025, in 2006, to the conducting of data collection in 2015. With the research objectives in mind, a thematic analysis was conducted to identify salient themes in order to address the research aims. The findings of this study show that youth participation in Jordan is neither inherent in the legal, political and administrative framework of the planning system nor in the embedded institutional settings within the planning practice of Jordan. Most importantly, cultural imperialism in Jordan weakens young people’s chances of being considered for any decision-making roles relevant to planning activities. Enhancing youth participation in spatial planning in Jordan requires the institutional capacity of urban governance to be built up to enable a more collaborative planning practice, in addition to applying principles of good governance in the planning system

What Kind of Future Will Our Children Inherit?

Over the years, my students, research associates, and I have reviewed the literature of psychology, ethics, ecology, climatology, and other areas of study to consider the direction in which our world is going and what kind of future our children will inherit. Our previous work focused on the nature of good and evil—with concern especially for goodness—through which we have considered good in the world and the application of good to achieve a better world. Our books concerned altruism, kindness, empathy, and moral responsibility for diverse others. In this book we concentrate on the areas of greatest concern regarding our future as a species. Scholars are warning us about the direction we are taking in this interconnected world. Many of these experts view our global situation as a “glass half empty”; their studies reveal a future that is bleak and on the verge of catastrophe. There are, however, other scholars who view the world and humanity’s future in more optimistic terms—those who see the “glass half full.” My own work indicates that goodness, defined as concern for others and for making the world a better place, is on the rise. Making the world a better place is not simply about the glass being half full or half empty; it is both at the same time. With the complexity of global trends comes major challenges, and one cannot say that one perception is correct and the other incorrect. It is much more complicated than that. We have an emergence of those who see the future as promising and perhaps even more harmonious than we have ever imagined, as well as those who believe that we are declining and ruining ourselves. A number of institutions, groups, governments, and individuals have taken these challenges to humanity seriously—have “seen the light”—and are trying to do something about the future state of the world. This book describes two sides to the future our children stand to inherit: the glass half full and the glass half empty of what has been the trajectory of the world, it seems, since the beginning of human history. The arc of human progress has at times taken major leaps forward; at other times it appears to have lain dormant, only to burst forth with a new energy at a later time. In this collection of writings, we have attempted to show both sides of the picture because to do otherwise would leave this endeavor incomplete. Depicting only the negative would lead one to think that there is nothing positive moving us forward; depicting only the positive would suggest that we have no further work to do. What kind of future will our children inherit? It is a future like all futures—it contains both an evolution of our species towards a higher level of consciousness and a resistance to such change. This has been the balancing act throughout human history. It will be incumbent upon our children to make sure that the glass of the future is half full. - Sam Oliner, Founder, Altruistic Behavior Institutehttps://digitalcommons.humboldt.edu/monographs/1014/thumbnail.jp
