This study presents an analysis of the unprecedented growth of international research collaboration in Europe in terms of distribution of co-authorship and citation of globally indexed publications over the last decade (2009–2018). The dynamics of change that emerge from this analysis are as follows: the increasing level of international cooperation is drawing key European systems away from institutional cooperation, with stable and strong national cooperation. National scientific output, i.e. the total number of publications, remains stable, and the entire increase in the number of publications over the period should be attributed to international co-authorship publications, which are the only driving force behind the increase in the number of publications in Europe. Due to the emergence of global networked science, in which the role of national policies in cooperation is decreasing and the role of scientists is growing, the key to the development of cooperation in Europe (and in Poland) is the readiness of individual scientists to undertake international cooperation. Researchers cooperate internationally when it is profitable for them in terms of academic prestige, scientific recognition and access to research funding, which is suggested by the three models proposed here (the model of credibility cycle in science, the model of prestige maximization and the model of global science). The total number of analyzed articles indexed in the Scopus database was 5.5 million, including 2.2 million articles written in international cooperation.

The successful application of a multi-clusteringbased neighborhood approach to recommender systems has led to increased recommendation accuracy and the elimination of divergence related to differences in clustering methods traditionally used. The Multi-Clustering Collaborative Filtering algorithm was developed to achieve this, as described in the author’s previous papers. However, utilizing multiple clusters poses challenges regarding memory consumption and scalability. Not all partitionings are equally advantageous, making selecting clusters for the recommender system’s input crucial without compromising recommendation accuracy. This article presents a solution for selecting clustering schemes based on internal indices evaluation. This method can be employed for preparing input data in collaborative filtering recommender systems. The study’s results confirm the positive impact of scheme selection on the overall recommendation performance, as it typically improves after the selection process. Furthermore, a smaller number of clustering schemes used as input for the recommender system enhances scalability and reduces memory consumption. The findings are compared with baseline recommenders’ outcomes to validate the effectiveness of the proposed approach.

In the current industrial scenarios those involved in production and services distribution

are called to deal with a plurality of stakeholders, considering different interests, readings

and positions. This paper exploits the concept of collaboration in this fast changes and

flexible scenario by describing the characteristics of collaboration among enterprises and

their scope. In this context, the purpose of all managers to maximize utility, to save cost or

to minimize of transaction costs is hard to be reached. Under this prospective, to collaborate

with other firms is a logical way to work and to pursue the previous objectives. The purpose

of this paper is to define all the aspects of collaboration, mainly among enterprises, and the

reasons that can drive a manager to stipulate a collaboration agreement. Two different ways,

through collaboration can rise, have been described: collaboration induced by external body

(top-down collaboration) or born in a spontaneous way (bottom-up). The management of

the collaboration and the identification of key performance indicators, able to control the

development of the network system, is addressed by exploiting the Italian network contract

and the case study of the energy cluster.

The objectives of this study were to develop a framework of the collaboration network, operational

performance, and reverse logistics determinants on the performance outcomes of the

auto parts industry, and to study the direct, indirect, and overall effects of the factors that

influence the performance outcomes of the auto parts industry. This quantitative research

utilized a questionnaire as the tool for data collection, which was completed by the managers

in the auto parts industry from 320 companies. According to the analysis with the Structural

Equation Modeling (SEM), it was found that the collaboration networks, operational

performance, and reverse logistics positively affect the performance outcomes; whereas, the

collaboration networks mainly affect the development of organizations by causing performance

outcomes to continue growing unceasingly, including the enhancement of sustainable

competitive capacity and the operational results of the auto parts industry.

Poles are today the largest group of family immigrants to Norway. Since Polish immigration is an intra-Euro-pean movement of labour, there are no specific laws or regulations, apart from labour regulations, pertaining to the introduction of Polish families to Norway and their settlement there. Consequently, there are few guidelines in schools and local authorities on dealing with Polish children in school. They receive the same introduction to school as immigrants from any other background, with no considera-tion of the specific characteristics of Poles. Equally, their parents are not eligible for the orientation courses and language classes that are offered to adult asylum seekers or refugees. As these are expen-sive, many Polish parents postpone language classes until they can afford them or find alternative ways of learning language and culture. In this article, I explore the inclusion of Polish children in Norwegian schools through the voices of teachers receiving Polish children in their classrooms and Polish mothers of children attending school in Norway. Interviews with both teachers and mothers reveal inadequate understandings of each other’s conceptions of school, education and the roles of home and school in the education of children. They also demonstrate a limited understanding of culturally bound interpre-tations of each other’s actions. Although both sides are committed to the idea of effective integration, we risk overlooking the social and academic challenges that Polish children face in Norwegian schools unless conceptions and expectations of school and education are articulated and actions are explained and contextualised. There is also a risk that cultural differences will be perceived as individual prob-lems, while real individual problems may be overlooked due to poor communication between schools and families. The data is drawn from an extended case study including classroom observations, inter-views with teachers and Polish mothers in Norway, and focus groups of educators and researchers in the field of social work.

Cloud-based computational environments can offer elastic and flexible services to wide audiences. Małopolska Educational Cloud was originally developed to support the day-to-day collaboration of geographically scattered schools with universities which organized online classes, led by university teachers, as an amendment to face-to-face teaching. Due to the centralized management and ubiquitous access, both the set of services provided by MEC and their usage patterns can be adjusted rapidly. In this paper we show how – during the COVID-19 pandemic – the flexibility of Małopolska Educational Cloud was leveraged to speed up the transition from in-class to remote teaching, both in the classes and schools which were already involved in the MEC project, and newly added ones. We also discuss the actions that were required to support the smooth transition and draw conclusions for the future.

In father’s footsteps or a problematic filiation. Dominique Jamet’s case – There is a phenomenon to be observed in contemporary French literature, namely the renewal of the novel through writing about self and the day-to-day reality in the context of family history. Writers reach into the past, often traumatic and painful, in order to rebuild their own broken identity, scarred by the memory of their parents’ troubled past. This is the case with Dominique Jamet. He returns to history with a capital H (the interwar period, World War Two, the Vichy regime and the subsequent issues of accounting for collaboration), so as to draw the figure of his father, Claude, an “intellectual” turncoat. The questionable filiation is the point of departure for writing two autobiographical texts. Also, it had undoubtedly been an inspiration for Un traître, a novel published in 2008, which is a fictitious reconstruction of the biography of Jacques Vasseur, an infamous French collaborator.

Although the COVID-19 vaccine has been recommended as the safer and more effective prevention for COVID-19 disease relative to other alternative medications, yet across the globe, many people are resistant to receiving it. Setting out to explain such a paradox, we conducted an online survey among a sample of Indonesians (N = 4758) when the World Health Organisation (WHO) granted authorisations for the clinical trial of various vaccines against COVID-19. The results revealed that participants’ support for theories that the COVID-19 vaccine is invented to harm their nation (i.e., COVID-19 vaccine conspiratorial beliefs) positively corresponded with the perceptions that international collaboration in the COVID-19 vaccine clinical trial is not aligned with their nation’s actual needs (i.e., the perceived assumptive international collaboration) and negative attitudes towards the vaccine. In turn, the perceived assumptive international collaboration was positively related to negative attitudes towards COVID-19 vaccine. We also showed that the positive relationship between COVID-19 vaccine conspiratorial beliefs and the perceived assumptive international collaboration in the vaccine clinical trial was more prominent among participants who were strongly resistant to take vaccines supplied by other countries due to national pride (i.e., vaccine national glorification).

In this paper, the stiffness and internal force of the finite element model of a cable-stayed bridge, arch bridge and cooperative system bridge with the same span are analyzed, and the stress characteristics of cooperative system bridge compared with arch bridge and cable-stayed bridge are studied. In the stiffness analysis, the live load deflections of the arch bridge (maximum deflection – 6.07 mm) and the cooperative system bridge (maximum deflection –6.00 mm) are similar, while the cable-stayed bridge (maximum deflection –16.27 mm) has a larger deflection. In the internal force analysis, compared with the internal force of the main girder, it can be seen that the girder of the cooperative system bridge reduces the girder-column effect compared with the cable-stayed bridge. The main girder of the cooperative system bridge reserves more stress than the arch bridge. In the stress analysis of arch rib, the axial force and bending moment of arch rib under dead load of cooperative system bridges are greater than the cooperative system bridge. The maximum difference of axial force and bending moment between arch bridge and cooperative system bridge is 16.2% and 58.8%, but there is no obvious difference under live load. In the stress analysis of the cable tower, the advantages of the cooperative system bridge are more obvious under dead load and live load. In the comparative analysis between the cable and the derrick, the dead load and live load are mainly carried by the derrick, and the derrick bears 84% dead load and 97% live load. The research results can provide reference for the stress analysis of similar bridge structures.

We examined the male-female collaboration practices of all internationally visible Polish university professors (N = 25,463) based on their Scopus-indexed publications from 2009–2018 (158,743 journal articles). We merged a national registry of 99,935 scientists with the Scopus publication database, using probabilistic and deterministic record linkage. Our database (“The Polish Science Observatory”) included all professors with at least a doctoral degree employed in 85 researchinvolved universities. We determined an “individual publication portfolio” for every professor. The gender homophily principle (publishing predominantly with scientists of the same sex) was found to apply to male scientists — but not to females. The majority of male scientists collaborate solely with males; most female scientists, in contrast, do not collaborate with females at all. Gender homophily in research-intensive institutions proved stronger for males than for females. Finally, we used a multi-dimensional fractional logit regression model to estimate the impact of gender and other individual-level and institutional-level independent variables on gender homophily in research collaboration.

Science at the state level consists of two distinct and heterogeneous systems: the global science system and national science systems. National science systems are deeply embedded in global science, and states seek to use global knowledge for domestic economic needs. However, harnessing the wealth of global knowledge can only be done through scientists. Consequently, the scientific strength of states in practice depends on the scientific strength of individual scientists. Their ability to collaborate internationally and to tap into the global scientific network is crucial. By remaining outside it and working within local research programs, the academic community risks being marginalized, losing the interest of national research funding patrons, and losing the ability to influence the development of science.

Video walls are useful to display large size video content. Empowered video walls combine display functionality with computing power. Such video walls can display large scientific visualizations. If they can also display high-resolution video streamed over a network, they could enable distance collaboration over scientific data. We proposed several methods of network streaming of highresolution video content to a major type of empowered video walls, which is the SAGE2 system. For all methods, we evaluated their performance and discussed their scalability and properties. The results should be applicable to other web-based empowered video walls as well.
