Business to business e-marketplaces: Investigating the factors that affect their e-services level of use
No full textAt the dawn of the 3rd millennium, the highly competitive and internationalized business environment dictates the use of electronic applications for the development at first, as well as, the continuation of any business activity regardless of its size and industrial sector focus. Besides, the fundamental and indispensable changes that take place in commercial procedures, due to the global penetration and sharp growth of Internet and ICT, bring about the creation of new and extremely innovative e-business models. Taking into consideration the aforementioned ascertainments, this PhD thesis focuses on the business-oriented investigation of B2B e-Marketplaces. These e-business models work as intermediaries by allowing multiple buyers and suppliers to meet on an electronic platform that rests on the Internet infrastructure in order to exchange information about products/services, conduct transactions online and adhere to other value-added e-services constituting an increasingly important application for IT. B2B e-Marketplaces have been characterized as one the most important accomplishments of the wide adoption of the Internet for entrepreneurship issues. Specifically, this PhD thesis provides an extended literature review regarding B2B e-Marketplaces. Based on this literature review, the scientific streams that have been arisen are presented, as well as, the determination of the basic conceptual approaches concerning their e-business model. However, the study of their empirical investigation revealed that the vast majority of the surveys on B2B e-Marketplaces have anchored on Roger’s diffusion of innovation theory and have limited their focus to the adoption stage of the assimilation process, where firms make the decision whether to adopt them. On the contrary, this PhD thesis aims to partly address the gap on this field by examining B2B e-Marketplaces on their post-adoption stage. As a consequence, the main scope of its empirical research is to investigate the factors that affect B2B e-Marketplaces’ level of use through a survey conducted to participants from all the active Greek B2B e-marketplaces. In particular, the examined factors cover three specific categories: a) firms’ internal environment, b) firms’ external environment and c) the specific characteristics of the B2B e-Marketplaces which they use; all of them form the related scientific hypotheses. In order to test these factors, a proposed conceptual framework is developed and a data analysis is conducted in two stages. The first step employs factor analyses using principal component analysis and orthogonal rotation in order to test the data validity and reliability, followed by discriminant analysis that confirms or rejects the formed hypotheses. Moreover, through this empirical research the current situation regarding Greek B2B e-Marketplace environment is presented. Specifically, the profile of the participants is provided by presenting their demographics, their perceived benefits from their participation, as well as, their future intention towards the use of the applied value-added e-services. The results reveal statistically significant influence of factors from the three examined categories, as well as, practical implications concerning involved firms’ B2B e-Marketplace profile.Στην αυγή της τρίτης χιλιετίας, το εντόνως ανταγωνιστικό και άκρως διεθνοποιημένο σύγχρονο επιχειρηματικό περιβάλλον επιτάσσει τη χρήση εφαρμογών Ηλεκτρονικού Επιχειρείν, αφενός, για την ανάπτυξη και, αφετέρου, για τη διατήρηση οποιασδήποτε επιχειρηματικής δραστηριότητας, ανεξαρτήτως τάξης μεγέθους και βιομηχανικού κλάδου επικέντρωσης. Παράλληλα, οι αναγκαίες και θεμελιώδεις διαφοροποιήσεις, οι οποίες παρατηρούνται στον τρόπο διενέργειας των εμπορικών διαδικασιών, ως απόρροια της καθολικής διείσδυσης και της ραγδαίας ανάπτυξης του διαδικτύου και των Τεχνολογιών Πληροφοριών και Επικοινωνίας (ΤΠΕ), επέφεραν τη δημιουργία νέων και ιδιαιτέρως καινοτόμων ηλεκτρονικών επιχειρηματικών μοντέλων. Βάσει αυτών των διαπιστώσεων, η παρούσα διατριβή επικεντρώνεται στην εξέταση, από επιχειρησιακής σκοπιάς (business-oriented approach), ενός εκ των κυριότερων επιτευγμάτων που προήλθαν από τη γενικευμένη υιοθέτηση του διαδικτύου ως μέσου για την ανάπτυξη επιχειρηματικότητας, του ηλεκτρονικού επιχειρηματικού μοντέλου των διεπιχειρησιακών (Business-to-Business - B2B) Ηλεκτρονικών Αγορών. Το συγκεκριμένο επιχειρηματικό μοντέλο λειτουργεί ως μεσάζοντας μεταξύ επιχειρήσεων-αγοραστών και επιχειρήσεων-προμηθευτών, παρέχοντας, μέσω της διαδικτυακής του πλατφόρμας, προηγμένες υπηρεσίες προστιθέμενης αξίας, τις οποίες εφαρμόζουν οι συμμετέχουσες εταιρείες για τη διεκπεραίωση των μεταξύ τους εμπορικών διαδικασιών. Ειδικότερα, στα πλαίσια της διατριβής, πραγματοποιείται μία εκτεταμένη βιβλιογραφική επισκόπηση και καθορίζονται τα σημαντικότερα πεδία έρευνας που έχουν, μέχρι σήμερα, καλυφθεί, ενώ παράλληλα καταγράφεται λεπτομερώς η εννοιολογική προσέγγιση του εξεταζόμενου Β2Β ηλεκτρονικού επιχειρηματικού μοντέλου. Ακόμη, μελετάται βάσει πρωτογενούς εμπειρικής έρευνας η υφιστάμενη κατάσταση στην Ελλάδα, σχετικά με το προφίλ των ενεργά συμμετεχουσών επιχειρήσεων στις εγχώριες Β2Β Ηλεκτρονικές Αγορές, μέσω της παράθεσης των επιμέρους δημογραφικών τους χαρακτηριστικών, των αντιλαμβανόμενων πλεονεκτημάτων από τη χρήση των παρεχόμενων υπηρεσιών, καθώς επίσης και των προθέσεών τους για τη μελλοντική αξιοποίηση των προσφερόμενων λύσεων. Λαμβάνοντας υπόψη τη διεθνή βιβλιογραφία, διαπιστώθηκε η ύπαρξη σημαντικού ερευνητικού κενού στο στάδιο μετά την υιοθέτηση των Β2Β Ηλεκτρονικών Αγορών (post-adoption stage), καθώς, περιορισμένος αριθμός μελετών έχουν παρουσιαστεί, οι οποίες να εξετάζουν τη μετέπειτα συμπεριφορά των συμμετεχουσών επιχειρήσεων, εντός των ορίων των Β2Β Ηλεκτρονικών Αγορών. Ως εκ τούτου, ο βασικός σκοπός της εμπειρικής μελέτης έγκειται στη διερεύνηση των παραγόντων, που επιδρούν στο βαθμό χρήσης των παρεχόμενων υπηρεσιών των Β2Β Ηλεκτρονικών Αγορών, καλύπτοντας συγκεκριμένα τρεις βασικές κατηγορίες εξέτασης: α) το εσωτερικό περιβάλλον των ενεργά συμμετεχουσών επιχειρήσεων, β) το αντίστοιχο εξωτερικό τους περιβάλλον και γ) τα ιδιαίτερα χαρακτηριστικά των ίδιων των Β2Β Ηλεκτρονικών Αγορών, που υιοθετούνται. Για την κάλυψη των παραπάνω αναγκών προτείνεται, στη διατριβή αυτή, ένα πρότυπο ερευνητικό πλαίσιο επίδρασης σειράς παραγόντων στο βαθμό χρήσης των Β2Β Ηλεκτρονικών Αγορών. Οι συνιστώσες-παράγοντες που ενσωματώνονται σε αυτό μελετώνται πρωτογενώς, βάσει ερευνητικών υποθέσεων, μέσα από την εφαρμογή αρχικά Διερευνητικών Παραγοντικών Αναλύσεων (Exploratory Factor Analyses) και, στη συνέχεια, Διαχωριστικής Ανάλυσης (Discriminant Analysis). Τα στατιστικά ευρήματα καταδεικνύουν την ύπαρξη σημαντικής επιρροής προς τις συμμετέχουσες εταιρείες, από παράγοντες και των τριών εξεταζόμενων κατηγοριών
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Online Shopping: Perceptions Of Greek Consumers
Full text linkThe sharp increase of Internet usage has transformed the way goods are bought and sold. Widely available online information about products and pricing has transferred many consumers from traditional to online stores. The scope of this paper is to examine the perceptions of Greek adopters and non-adopters of online shopping in terms of demographic profile, consumers’ expectations of online stores, advantages and problems related to online purchases. Additionally, the reasons for using or avoiding online shopping, as well as, the types of preferred products were studied. The findings of this paper are useful in explaining consumers’ online buying behaviour. The empirical results provide important managerial implications and set the basis for further research on this field
The mobile shopping engagement: Surveys' review and empirical study
No full textMobile shopping (m-shopping) has become extremely significant for both marketing and retail selling. Despite the fact that m-shopping has evolved into a popular alternative approach for purchasing products and services worldwide, the research regarding the extent of its adoption is still on a mediocre level and in certain countries, such as Greece, is rather limited. It is highly important to analyze and fully comprehend several factors that influence the acceptance of mobile technologies by consumers in order to motivate and support sellers' mobile strategy. The objective of this research is to approach the factors that affect m-shopping with the analysis of two categories of mobile users, those who have already been involved in m-shopping and those who have not. Specifically, this work aims to explore and explain, in an introductory way, the critical factors that tend to influence m-shopping acceptance in order to predict both the consumers' attitude towards m-shopping and their purchasing behavior via mobile devices, based on literature review and empirical survey
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
