Web Service Applications and Consumer Environments Based on ICT-Driven Optimization

Networking is the use of physical links to connect individual isolated workstations or hosts together to form data links for the purpose of resource sharing and communication. In the field of web service application and consumer environment optimization, it has been shown that the introduction of network embedding methods can effectively alleviate the problems such as data sparsity in the recommendation process. However, existing network embedding methods mostly target a specific structure of network and do not collaborate with multiple relational networks from the root. Therefore, this paper proposes a service recommendation model based on the hybrid embedding of multiple networks and designs a multinetwork hybrid embedding recommendation algorithm. First, the user social relationship network and the user service heterogeneous information network are constructed; then, the embedding vectors of users and services in the same vector space are obtained through multinetwork hybrid embedding learning; finally, the representation vectors of users and services are applied to recommend services to target users. To verify the effectiveness of this paper’s method, a comparative analysis is conducted with a variety of representative service recommendation methods on three publicly available datasets, and the experimental results demonstrate that this paper’s multinetwork hybrid embedding method can effectively collaborate with multirelationship networks to improve service recommendation quality, in terms of recommendation efficiency and accuracy.

RELATIONSHIP NETWORK CHARACTERISTICS OF SPORTS AND NON-SPORTS YOUNG ADOLESCENTS

From school onwards, children spend more and more time with their peers without direct adult supervision. In peer groups, the emphasis is on shared interests, understanding and trust, rather than joint activities. The biological changes associated with adolescent sexual maturation also lead to changes in social relationships. The topic is particularly topical now, in the wake of the COVID-19 pandemic, when opportunities for face-to- face communication have been significantly reduced, leading in many cases to a transformation of relationships. Playing sport expands the individual's range of experience: he or she is exposed to a new social environment, has the opportunity to form new relationships, and encounters a new set of values and norms. All this shapes their personality, their individuality and has an impact on their whole life. However, many children today do not play sport regularly, partly because of the increased mental workload and demands and the resulting lack of time. In my research, I was looking for answers to the question of how regular sporting activities affect the social relationships of young adolescents. As the data from my research show, regular sporting activity has a beneficial effect on both the extension and the intensity of children's relational networks, especially for those playing team sports.

Researching public art and public space

This special issue is devoted to research on the changing paradigms of public art, and of public spaces. Today all art can be characterized as public since it is mediated via relational networks. The shift of paradigm from modernist art to contemporary art coincides with this shift of paradigm – from consumption to communication – in the sense that advanced art practices had already absorbed the change from individual mediation to relational networks. In the communication network of relations, artists and works are constitutive elements. Without the works and the artists, the relational network does not exist, and vice versa: Without the network of relations, neither artists nor works are made visible. This constitutive reciprocity of relations is decisive both for theorists doing research on public art and art in public spaces, as well as for artists who are doing research in public spaces.

Neither “Celtic” nor “Dacian”: The Site of Židovar at the Edges of La Tène, Carpathian and Roman Worlds

The paper reviews long-standing interpretation of the late Iron Age site of Židovar as “Celtic”, “Dacian” and “Celto-Dacian”. Arguing that this standpoint is derived from biased culture-historical ethno-determinism, the evidence is reconsidered from excavation journals of Branko Gavela and published research on Židovar. Evidential basis is discussed, such as sratigraphic difficulties and chronology, as well as some common misconceptions of the site’s characteristics. Deadlocks are emphasized regarding the conclusions on its ethnic belonging. The paper calls for a new approach that goes beyond ethno-cultural determinism and urges the employment of “relational locality”. This perspective considers the site and its immediate surroundings as the first order community, i.e. the spatio-social focal point entangled in diverse, multidirectional and supra-regional relational networks. This would mean that the community of Židovar actively mediated different templates coming from the “globalized” koines of La Tène Pannonian, Danubian-Carpathian and Roman worlds, and bricolaged them in distinctive local ways.

ImmunAL: a frame to identify the immunological markers for Mild Moderated Alzheimer's Disease applying Multiplex Network Model

Identification of immunological markers for neurodegenerative diseases resolve issues related to diagnostic and therapeutic. Neuro-specific cells experience disruptive mechanisms in the early stages of disease progression. The autophagy mechanism, guided by the autoantibodies, is one of the prime indicators of neurodegenerative diseases. Identifying autoantibodies can show a new direction. Detecting influential autoantibodies from relational networks viz., co-expression, co-methylation, etc. is a well-studied area. However, none of the studies have considered the functional affinity among the autoantibodies while selecting them from a relational network. In this regard, a two-layered multiplex network based framework has been proposed,whereby the layers consist co-expression and co-semantic scores. The networks have been formed using three distinct cases viz., diseased, controlled, and a combination of both. Subsequently, a random walk with restart mechanism has been applied to identify the influential autoantibodies, where layer switching probability and restart probability are 0.5 and 0.4 respectively. Next, pathway semantic network has been formed considering the autoantibody associated pathways. EPO and IL1RN, associated with a maximum number of pathways, are identified as the two most influential autoantibodies. The network also provides insights into possible molecular mechanisms during the pathogenic progression. Finally, MDPI and CNN3 are also identified as important biomarkers.

Key Node Discovery Algorithm Based on Multiple Relationships and Multiple Features in Social Networks

The key nodes play important roles in the processes of information propagation and opinion evolution in social networks. Previous work rarely considered multiple relationships and features into key node discovery algorithms at the same time. Based on the relational networks including the forwarding network, replying network, and mentioning network in a social network, this paper first proposes an algorithm of the overlapping user relational network to extract different relational networks with same nodes. Integrated with these relational networks, a multirelationship network is established. Subsequently, a key node discovery (KND) algorithm is presented on the basis of the shortest path, degree centrality, and random walk features in the multirelationship network. The advantages of the proposed KND algorithm are proved by the SIR propagation model and the normalized discounted cumulative gain on the multirelationship networks and single-relation networks. The experiment’s results show that the proposed KND method for finding the key nodes is superior to other baseline methods on different networks.

The Digitalization Influence on the Transformation of Public Administration Methodology

The article shows that the ongoing processes of networkization, digitalization and hybridization lead to the creation of such a sociotechnical phenomenon as information and analytical platforms, which actualize a new type of social network relations between authorities and citizens in the public space of communications. In these conditions, a new methodology of public administration is required, which would take into account the digital realities of the modern world. According to the authors, the new concept of public administration should be built taking into account the development of a methodology for the following mutually conditioned processes: 1) creation of information and analytical platforms of the digital society; 2) formation of social structures in the network space; 3) configuration of relational networks for solving socially significant problems. It should be based on the actor-network concept and the digitalization ethics, the social network analysis, the relational sociology, the concept of figuration, the fractal-evolutionary concept, the concept of configuring a relational network of stakeholders.

Rock Art Modification and its Ritualized and Relational Contexts

Australia has some of the most complex and extensive examples of modified rock art (e.g., superimposed, re-painted, re-drawn, re-pecked) in the world. Typically used to document style-based chronological sequences and address questions of meaning and intention, less well known are the relational networks within which these ritual modification practices are embedded. In this article we explore the ritual rock art modification relationship to further highlight the value of a ritual-based approach to access and enhance understanding of modified rock art. Central to this approach is the idea that modified motifs do not exist in isolation—their placement, the actions, rules, and structures linked to the modification process, along with the surrounding landscape, are all part of relational networks that extend across multiple social and cultural realms. By identifying key themes associated with this ritual practice, we explore relational qualities to further understand the ritual rock art relationship to broaden archaeological and ethnographic understanding of rock art.

Resocialisation of Experienced Employees: Challenges in a Context of Change

Management research in the field of organisational socialisation has largely focused on the incorporation of new recruits into stable organisations. This research study looks instead at the resocialisation of employees facing planned changes in their role expectations. Conducted with the assistance of a leading European railway company that had undergone a transformation process, the study is a qualitative piece of research mobilising 35 cases of employee resocialisation. The main findings are threefold: they reveal four typical forms of resocialisation (conviction, resourcefulness, resignation and transgression) spanning the continuum from success to failure; indicators of successful and failed resocialisation need to be revisited; cognitions or emotions (adherence) and behaviours (role orientation) are clearly aligned with conviction and transgression, as are those socialisation dimensions that can serve as either resources or barriers. Conversely, resourcefulness and resignation reveal ambivalent forms of resocialisation. Finally, experienced employees tend to face three kinds of resocialisation resources and barriers (relational networks, biographical continuities or discontinuities and organisational roles), each of which is specific in nature. Lessons can be drawn from these discoveries with regard to the resocialisation of experienced employees.
