This paper examines the process of repurposing “Big Brother” surveillance cameras as a public utility. The authors set out to create a large scale game with two principal objectives: first, to challenge the conventional and unequal relationship in the design and deployment of surveillance technology; and second, to test surveillance cameras’ ability to reconfigure social relations in public spaces so as to encourage collaboration among strangers. The system uses motion sensed in surveillance video feeds towards completing a shared goal in a game context. This paper describes two major design iterations and installations of the authors’ game system and assesses the strengths and failings of both in pursuit of the stated social aims.

Role Of The State

In Vietnam, the construction of hydropower projects has contributed significantly in the cause of industrialization and modernization of the country. The place where hydropower projects are built is mostly inhabited by ethnic minorities - communities that rely primarily on land, a very important source of livelihood security. In the context of the lack of common productive land in resettlement areas, the orientation for agricultural production is to promote indigenous knowledge combined with increasing scientific and technical application; shifting from small-scale production practices to large-scale commodity production. However, the research results of this article show that many obstacles in the transition process are being posed such as limitations on natural resources, traditional production thinking or the suitability and effectiveness of scientific - technical application models. When agricultural production does not ensure food security, a number of implications for people’s lives are increasingly evident, such as poverty, preserving cultural identity, social relations and resource protection. Since then, it has set the role of the State in researching and building appropriate agricultural production models to exploit local strengths and ensure sustainability.

Social Collective

A large-scale Cyber-Physical System (CPS) such as a smart grid usually provides service to a vast number of users as a public utility. Security is one of the most vital aspects in such critical infrastructures. The existing CPS security usually considers the attack from the information domain to the physical domain, such as injecting false data to damage sensing. Social Collective Attack on CPS (SCAC) is proposed as a new kind of attack that intrudes into the social domain and manipulates the collective behavior of social users to disrupt the physical subsystem. To provide a systematic description framework for such threats, we extend MITRE ATT&CK, the most used cyber adversary behavior modeling framework, to cover social, cyber, and physical domains. We discuss how the disinformation may be constructed and eventually leads to physical system malfunction through the social-cyber-physical interfaces, and we analyze how the adversaries launch disinformation attacks to better manipulate collective behavior. Finally, simulation analysis of SCAC in a smart grid is provided to demonstrate the possibility of such an attack.

Naive Approach

In smart city scenarios, the huge proliferation of monitoring cameras scattered in public spaces has posed many challenges to network and processing infrastructure. A few dozen cameras are enough to saturate the city’s backbone. In addition, most smart city applications require a real-time response from the system in charge of processing such large-scale video streams. Finding a missing person using facial recognition technology is one of these applications that require immediate action on the place where that person is. In this paper, we tackle these challenges presenting a distributed system for video analytics designed to leverage edge computing capabilities. Our approach encompasses architecture, methods, and algorithms for: (i) dividing the burdensome processing of large-scale video streams into various machine learning tasks; and (ii) deploying these tasks as a workflow of data processing in edge devices equipped with hardware accelerators for neural networks. We also propose the reuse of nodes running tasks shared by multiple applications, e.g., facial recognition, thus improving the system’s processing throughput. Simulations showed that, with our algorithm to distribute the workload, the time to process a workflow is about 33% faster than a naive approach.

Purpose Brand “Likes” on Facebook facilitate self-expression, forming part of consumers’ virtual selves. Yet, consumers’ brand “Likes” may bear little resemblance to their material realities. This paper aims to test similarities of brand image with self-image for Facebook “Likes” to determine whether self-congruence with a “Liked” brand leads to positive offline brand outcomes. It also investigates whether consumers’ perceptions about their Facebook social relations influence self-congruent brand “Likes”. Design/methodology/approach A large-scale survey was conducted of regular Facebook users who “Liked” brands. Data from 438 respondents was analysed and hypotheses tested using structural equation modeling. Findings Empirical results show that the perceived self-congruence with a “Liked” brand increases with social tie strength. Perceived social tie strength is informed by perceived attitude homophily. When the perceived self-congruence with a “Liked” brand is higher, brand love and word of mouth (WOM) are enhanced. Consumers also have greater brand loyalty and offer more WOM when brands are loved. Research limitations/implications Findings demonstrate the influence of consumers’ cognitive network on “Likes” and brand outcomes. Further replication would enhance generalisability. Future research should use a wider sample and investigate other variables. Practical implications Findings support managers seeking to grow and analyse Facebook “Likes” by providing insights into brand loyalty, brand love and WOM for “Liked” brands. Originality/value The paper addresses the dearth of research exploring how consumers’ perceptions of their Facebook network influence their online brand behaviour and how perceived self-congruence with a “Liked” brand relates to brand outcomes.

Strategies of the Familiarization of Things in Polish Regained Territories with the Special Attention to the Private Space This article discusses the presence of things and their modes of functioning in the private and, to some extent, also public spaces of the Recovered Territories in Poland after the Second World War. In this article, things are perceived as active agents, crucial for developing many different social relations that have to be created anew in the unknown cultural and material environment. New things that people come across are also treated here as objects that can reveal traumatic tensions caused by the necessity of the existence in the unfamiliar space that was left behind by the war enemies. This new private space that the Polish people have to live in needs to be domesticated and treated as a part of the everyday life. Strategies that are used to familiarize the former German cultural heritage are the main focus of this article.Cтратегии освaивания вещей на воссоединённых землях Польши особенно в личном пространствеВ этой ста­тье представлена проблема присудствия вещей и способа их функционирования особенно в личном пространстве на воссоединённых землях Польши после второй мировой войны. Bещи выступают здесь как активные актёры многих разнообразных общественных соотношений, которые надо создать заново в незнакомой материальной и культурнoй среде. Oдновременно новонайденные предметы могут вызывать травматические реакции у переселенцев, которые возникают как результат необходимости жизни в домах покиданных врагом. Это новое про­странство должно быть освоенное новыми жителями. Metoды ведущие к этой цели являются темой представленного здесь анализa.

The Social

Developed economies of individual states are becoming an example and set the pace of development for others. Countries that are now leading the way have brought people to the forefront with their spiritual, human and intellectual qualities. Ukraine has not yet taken this experience and goes in the opposite direction, devaluing all kinds of relations in the state. The purpose of the research is to highlight the state of the organization of interaction of the population with all branches of power in order to understand and identify the steps towards the development of the knowledge economy. The object of research is the social complex of living conditions of the population of Ukraine, as the basis for the formation of value orientations of the knowledge economy. The methods used of the research were the practical side of the built relationship between the population and authorities at all levels. The hypothesis of the research is the idea that everyone should take his worthy place to shift a car called State in the direction of improving the quality of social relations, which will serve to increase the economic component. The statement of basic materials. To date, the state of interaction and communication with government is striking by the depreciation and neglect of moral, ethical and legal standards. The incompetence of the authorities and the high corruption of all structures leads to disruption of relations between all segments of the population. The great anti-social orientation of many laws and reforms does not allow a citizen to develop and realize his potential, as the consciousness of more than half of the population has mastered a single opinion – how to survive. The originality and practical significance of the research. To achieve economic growth and the implementation of large-scale innovation, you need to start with radical changes in the social plane. The proposed steps will improve the relations between the people and the authorities, establish dialogue and restore confidence in the state apparatus. Conclusions of the research. Based on this study, we can understand that we need to radically revise the relations between the population and the authorities and to be guided by common sense when making decisions that can harm another person

The Masses

The recent advent and wide adoption of Social Bookmarking Systems (SBS) has disrupted the traditional model of online content publishing and consumption. Until recently, the majority of content consumed by people was published as a result of a centralized selection process. Nowadays, the large-scale adoption of the Web 2.0 paradigm has diffused the content selection process to the masses. Modern SBS-based applications permit their users to submit their preferred content, comment on and rate the content of other users and establish social relations with each other. As a result, the evolution of popularity of socially bookmarked content constitutes nowadays an overly complex phenomenon calling for a multiaspect analysis approach. This chapter attempts to provide a unified treatment of the phenomenon by studying four aspects of popularity of socially bookmarked content: (a) the distributional properties of content consumption, (b) its evolution in time, (c) the correlation between the semantics of online content and its popularity, and (d) the impact of online social networks on the content consumption behavior of individuals. To this end, a case study is presented where the proposed analysis framework is applied to a large dataset collected from Digg, a popular social bookmarking and rating application.

Air pollution is an important environmental issue that has a direct effect on human health and ecological balance. Factories, power plants, vehicles, windblown dust and wildfires are some of the contributors of to pollution. Reasonable simulation tools exist for evaluating large scale sensor networks, ; however, they fail to capture significant details of node operation or practical aspects of wireless communication. Real life testbeds, capture the realism and bring out important aspects for further research. In this paper, we present an implementation of a wireless sensor network testbed for automatic and real-time monitoring of environmental pollution for the protection of public spaces. The paper describes the physical setup, the sensor node hardware and software architecture for “anytime, anywhere” monitoring and management of pollution data through a single, Web-based graphical user interface. The paper presents practical issues in the integration of sensors, actual power consumption rates and develops a practical hierarchical routing methodology.

Development Approach

Since the turn of the millennium, the landscape of development in Africa has undergone a dramatic shift. China has significantly expanded its foreign aid and investment in the region, decentering the West as Africa's main development partner. What is largely missing from China-Africa scholarship, however, is attention to how the new Chinese presence in Africa is both embedded in and altering everyday social relations. This article examines these issues in a rural setting in Uganda that is in the midst of a large-scale transformation into a China-funded industrial park. It reveals that the complex new politics of Chinese development assistance are intertwined with, and often exacerbate, existing social inequalities based in politics, class, ethnicity, and race. More conceptually, these dynamics demonstrate the need to rethink how we frame development as a transnational field of social practice. China is more than an outlier within the global field of development and instead should be viewed as pursuing its own form of development, what I call “developmental pragmatism.” As this case study illustrates, this developmental pragmatism often turns on synergies between the business-focused development approach of the Chinese and the priorities of more authoritarian governments—synergies that require much greater critical attention.

E-mail-based conversations between thousands of people-very large-scale conversations (VLSCs)-now take place in a variety of on-line public spaces such as Usenet newsgroups and large listservs. This article describes the author's prototype Conversation Map system, which can automatically analyze and graphically summarize thousands of e-mail messages exchanged in VLSCs. Example conversation maps of nine VLSCs are presented. Finally, the sociolinguistic analysis performed by the Conversation Map is discussed as a form of artificial dialectics, and the graphical summaries produced by the system are considered as potential common ground between participants in a VLSC.
