Interdisciplinarity master programs in Greek universities: Οrganization and cognitive conditions

Το κείμενο αυτό επικεντρώνεται στα διεπιστημονικά προγράμματα μεταπτυχιακών σπουδών των ελληνικών πανεπιστημίων. Για την ανάλυση χρησιμοποιήθηκαν στοιχεία από την Κοινωνιολογία των Οργανώσεων (Mayntz) και την Κοινωνιολογία της Επιστήμης (Whitley). Το βασικό μας επιχείρημα είναι ότι το πανεπιστήμιο και οι βασικοί συντελεστές του υιοθέτησαν τη διεπιστημονικότητα, πρώτον, για να αυξήσουν τους ιδρυματικούς οικονομικούς πόρους, και δεύτερον, με φροντίδα να μη διαταραχθεί η εσωτερική θεσμική δομή και ο συσχετισμός δυνάμεων μεταξύ των βασικών δρώντων εντός του πανεπιστημίου. Πράγματι, από τη μια, τα πανεπιστήμια ανταποκρίθηκαν στις δημόσιες προσκλήσεις εκδήλωσης ενδιαφέροντος για διεπιστημονικά προγράμματα, χρηματοδοτούμενα από Κοινοτικούς πόρους, με στόχο τον εμπλουτισμό των υποδομών τους. Από την άλλη, οι νέες δομές και λειτουργίες (διεπιστημονικά προγράμματα σπουδών) παρέμειναν χαλαρέςκαι αδύναμες. Ως συνέπεια, οι εσωτερικές σχέσεις των θεσμικών δρώντων προφυλάκτηκαν. Έτσι, η διεπιστημονικότητα φαίνεται να είναι μια χαμηλής προτεραιότητας υπόθεση. Παρόλα αυτά, είναι ενδιαφέρον να δει κανείς ότι πάνω από 10 χρόνια από την ευρωπαϊκή χρηματοδότηση, η πλειοότητα αυτών των προγραμμάτων παρέμενε ενεργή, τουλάχιστον ως τις τελευταίες θεσμικές αλλαγές.This paper focuses on the development of interdisciplinarityin the Master’s programs in Greek universities.

Shear connection requirements for composite cellular beams

[EN] Beams with regular circular web openings (cellular beams) are often used in composite construction. Rules for the minimum degree of shear connection in composite beams are presented in Eurocode 4 but were derived for solid web beams in propped construction. This paper investigates the degree of shear connection requirements for composite cellular beams, focusing on the combined effect of using a steel section with regularly spaced, large circular web openings and unpropped construction conditions. The effect of the diameter and the spacing of the openings is also investigated. In order to provide rules for the minimum degree of shear connection in cellular beams, parametric finite element (FE) analyses were carried out for beams in the span range of 9 to 18 m. The results were calibrated against a 15.3 m span composite cellular beam test with a low degree of shear connection. The proposed minimum degree of shear connection requirements for beams with regular circular web openings are presented for both propped and unpropped construction, and for symmetric and asymmetric steel sections. Comparisons are made with equivalent beams with solid webs (no openings) and it is shown that significant relaxation in the codified minimum degree of shear connection to the current version of Eurocode 4 can be justified for composite cellular beams.Aggelopoulos, E.; Hanus, F.; Lawson, M.

FACTORS THAT SUPPORT THE DEVELOPMENT OF FUR FARMS: THE CASE STUDY OF GREECE

This study aims to discuss the key factors that can contribute to the development of the fur industry in Greece. The industry consists of two sub-sectors i.e. production and processing of fur skins (raw material), and the production of fur garments. The profitability of fur-bearing farms, considered from the perspective of investment and further international fur trade, and both these were examined in this study because these two sub-sectors are closely linked. The results obtained from the analysis of the two fur production sub-sectors showed that the investment of capital in the industry can expect positive returns while at the same time creating well-paid jobs. Although not presenting a comparative advantage, but the foreign trade of fur garments produced in the region can gain competitiveness if some of the strategies used by Greek fur companies are adjusted. Results of the current study can be concluded that despite the weaknesses that emerge from the results of this study, both sub-sectors of the fur industry can make a significant contribution to the development of the local community of Western Macedonia

Presynaptic control of transmission through group II muscle afferents in the midlumbar and sacral segments of the spinal cord is independent of corticospinal control.

Transmission of information from the terminals group II muscle afferents is subject to potent presynaptic modulation by both segmental group II and cutaneous afferents and by descending monoaminergic systems. Currently it is unknown whether descending corticospinal fibres affect this transmission. Here we have examined whether corticospinal tract activation modulates the size of monosynaptic focal synaptic potentials (FSPs) evoked by group II muscle afferents, and the excitability of intraspinal terminals of group II afferents, both of which are indices used to show presynaptic control. Conditioning stimulation of corticospinal pathways had no effects on the sizes of group II evoked FSPs in the midlumbar or sacral segments at either dorsal horn or intermediate zone locations. These stimuli also had no effect on the excitability of single group II afferent terminals in the dorsal horn of the midlumbar segments. As positive controls, we verified that the corticospinal conditioning stimuli used did effectively depress FSPs evoked from cutaneous afferents recorded at the same spinal locations as the group II field potentials in all experiments. Corticospinal tract conditioning stimuli did not consistently enhance or reduce the depression of group II FSPs that was evoked by stimulation of ipsilateral segmental group II or cutaneous afferents; in the large majority of cases there was no effect. The results reveal that the control of transmission of information from group II afferents in these regions of the spinal cord is independent of direct corticospinal control

The main purpose of the article is formulation of ways and favorable conditions and possibilities for development of agro and eco-tourism in rural areas of Uzbekistan. At the same time, inflow of tourists using approach of “Gravity” model was analyzed in order to identify theoretical and practical aspects of alternative identification of the share of tourism services in contemporary development of rural areas and agriculture of Samarkand region. Within the framework of our research, we studied theoretical and practical aspects of agro and eco-tourism and the rural areas of Samarkand region and collected statistical data was analyzed on the basis of “Gravity” model and forecasted indicators of tourism inflow were identified. As the result of the research, scientific and practically significant recommendations have also been developed and figured out

Minimum degree of shear connection in composite beams in buildings

[EN] Composite floors are often used in building construction where beams typically span from 6 to 18 m. They are commonly used together with decking of 50 to 80 mm depth that spans 3 to 4.5 m between the beams. Rules for the minimum degree of shear connection in composite beams are presented in Eurocode 4 and other international Codes, and were derived for beams in propped construction.Eurocode 4 defines a minimum limit for the degree of shear connection, primarily to ensure that slip at the steel-concrete interface does not exceed a limiting value. This limit is proportionate to the beam span and also depends on the steel strength and the asymmetry of the flange areas of the section. Currently, many designs cannot achieve the codified degree of shear connection demands, since it is not possible to accommodate a sufficient number of shear connectors on the span as dictated by the spacing of the deck ribs. However, there are special cases which are not explicitly accounted for in Codes. This paper aims to investigate the degree of shear connection requirements in such cases, including beams that are unpropped in construction, beams that are not fully utilised in bending because serviceability criteria govern their design and beams that are predominantly loaded by point loads rather than uniform loading.The results from parametric finite element analyses carried out using ANSYS for beams in the span range of 6 to 18 m are presented. The finite element models have been calibrated against composite beam tests. Comparisons are made with the current Eurocode 4 provisions and modifications are proposed where appropriate.Aggelopoulos, E.; Couchman, G.; Lawson, M. (2018).

Ο ρόλος των μέσων κοινωνικής δικτύωσης στη δημιουργία διαπροσωπικών σχέσεων μεταξύ καταναλωτών και προϊόντων

Σκοπός αυτής της έρευνας είναι η διερεύνηση του ρόλου των μέσων κοινωνικής δικτύωσης στη δημιουργία διαπροσωπικών σχέσεων μεταξύ καταναλωτών και προϊόντων. Η ποσοτική δημοσκοπική και συσχετιστική μέθοδος χρησιμοποιήθηκε για τους σκοπούς αυτής της εργασίας, μέσω ενός ερωτηματολογίου που αναρτήθηκε στην πλατφόρμα Google Forms. Το δείγμα της έρευνας αποτελείτο από 90 καταναλωτές που επιλέχθηκαν τυχαία. Από τις απαντήσεις των ερωτηθέντων καταδείχθηκε πως τα μέσα κοινωνικής δικτύωσης αποτελούν πηγή πληροφοριών που χρησιμοποιούν όταν αποφασίζουν να αγοράσουν κάτι. Ουσιαστικά, καταδείχθηκε πως οι ερωτηθέντες χρησιμοποιούν τα μέσα κοινωνικής δικτύωσης ως πηγή ενημέρωσης για νέα προϊόντα και προσφορές, καθώς και ανάγνωση κριτικών από άλλους καταναλωτές, ώστε να οδηγηθούν στη λήψη αποφάσεων. Επομένως, η παροχή και αναζήτηση πληροφοριών και η επικοινωνία βρέθηκαν να οδηγούν στη διαμόρφωση διαπροσωπικών σχέσεων μεταξύ προϊόντων και καταναλωτών. Οι εταιρείες θα πρέπει να δώσουν έμφαση στον τρόπο παρουσίασης των πληροφοριών και στο περιεχόμενο αυτών των πληροφοριών και των ενημερώσεων, αλλά και στο ότι οι καταναλωτές δεν διαμορφώνουν στενές σχέσεις με τις μάρκες μέσω των μέσων κοινωνικής δικτύωσης. Περισσότερες έρευνες αγοράς από μέρους των εταιρειών, καθώς και έρευνες σε καταναλωτές και σε στελέχη μάρκετινγκ των εταιρειών είναι απαραίτητες.The purpose of this research is to investigate the role of social media in creating interpersonal relationships between consumers and products. The quantitative and correlational method was used for the purposes of this work, through a questionnaire posted on the Google Forms platform. The survey sample consisted of 90 randomly selected consumers. The answers of the respondents showed that social media is a source of information that they use when they decide to buy something. In fact, it was shown that respondents use social media as a source of information about new products and offers, as well as reading reviews from other consumers, in order to lead them to make decisions. Therefore, the provision and search of information and communication were found to lead to the formation of interpersonal relationships between products and consumers. Companies should emphasize the way information is presented and the content of this information and updates, but also that consumers do not form close relationships with brands through social media. More market research by companies, as well as research on consumers and corporate marketing executives are needed
