In the last decades borderlands studies have been rapidly developing in various disciplines. Within the changing function of European borders (from separating line between two souvereign states to borderscapes of intercultural flows and fluid identity) the focus of border scholars moved towards social relations and bottom-up perspective. Thus, borderlands are perceived as laboratories of European integration and multicultural spaces. For the aim of this article, borderlands are defined as spaces located on the geographical border between different states, nations and cultures that are objects of European Union cohesion policy. By analysing the Eurobarometer survey on cross-border cooperation I try to demonstrate differences between border regions covered by the Interreg cross-border cooperation programmes in terms of cross-border practices, general trust in others and attitudes towards citizens of neighbouring countries.
Different methods are used for production of bronze bearings. In terms of technical specifications, the success of each of these methods depends on the bond’s strength and in terms of economic, the production method is important. In this study, the aim is to study the strength and microstructure of steel-bronze thrust bearing bond that has been produced through the casting using pre-mold. In this study, in order to bond, the raw metals are chemically washed with sulfuric acid solution for five minutes at first. Then, the molten bronze SAE660 is cast in a structural steel S235JR pre-mold. The bond’s strength has been measured using the shear test three times; the measurement of bond’s length has been done using field emission scanning electron microscope (FESEM). The results indicate that the strength of the bond is at least 94.8 MPa and bond’s length is 0.45 micrometers. Therefore, this method was successful for trust bearing application.
The data aggregation process of wireless sensor networks faces serious security problems. In order to defend the internal attacks launched by captured nodes and ensure the reliability of data aggregation, a secure data aggregation mechanism based on constrained supervision is proposed for wireless sensor network, which uses the advanced LEACH clustering method to select cluster heads. Then the cluster heads supervise the behaviors of cluster members and evaluate the trust values of nodes according to the communication behavior, data quality and residual energy. Then the node with the highest trust value is selected as the supervisor node to audit the cluster head and reject nodes with low trust values. Results show that the proposed mechanism can effectively identify the unreliable nodes, guarantee the system security and prolong the network lifetime.
The idea of using the Cloud of Things is becoming more critical for e-government, as it is considered to be a useful mechanism of facilitating the government’s work. The most important benefit of using the Cloud of Things concept is the increased productivity that the e-governments would achieve; which eventually would lead to significant cost savings; which in turn would have a highly anticipated future impact on egovernments. E-government’s diversity goals face many challenges; trust is one of the major challenges that it is facing when deploying the Cloud of Things. In this study, a new trust framework is proposed which supports trust with the Internet of Things devices interconnected to the cloud; to support the services that are provided by e-government to be delivered in a trusted manner. The proposed framework has been applied to a use case study to ensure its trustworthiness in a real mission. The results show that the proposed trust framework is useful to ensure achieving a trusted environment for the Cloud of Things for it to continue providing and gathering the data needed for the services that are offered by users through E-government.
The article summarizes panel discussions led at the Polish Scientific Networks conference. It covers the topics of social and (un)social innovations, their sources, and applications, as well as the new approaches to the concept of the wisdom of the crowds (as opposed to swarm mentality). The article draws on academic research on trust and distrust, declining reliance on formal expertise and a turn against the science, and posttruth society phenomenon. The article concludes with observations about risk aversion in different cultures, to suggest some practical solutions in education programs, needed to address the challenges of the future.
The paper presents the results of experimental validation of a set of innovative software services supporting processes of achieving, assessing and maintaining conformance with standards and regulations. The study involved several hospitals implementing the Accreditation Standard promoted by the Polish Ministry of Health. First we introduce NOR-STA services that implement the TRUST-IT methodology of argument management. Then we describe and justify a set of metrics aiming at assessment of the effectiveness and efficiency of the services. Next we present values of the metrics that were built from the data collected. The paper concludes with giving the interpretation and discussing the results of the measurements with respect to the objectives of the validation experiment.
