A Portuguese Study

A balanced implementation of functionalities within a commercial internet presence is important, because of not only the involved complexity and cognitive load required in their use, but also for financial reasons. Investing money on features (e.g., software modules, programming time, maintenance and update, etc.) that are not valued by online consumers, hinders an efficient allocation of resources, especially when financial resources are scarce, a situation that corresponds too many small businesses operating on the internet. However, literature provides little help for managers to decide which functionalities should be implemented, according to a rational basis. Within this context, this research sought to fill in the gap between literature review and the need for helping companies to understand better how to build and keep online businesses. The authors work identified 16 essential functionalities grouped into four sets: order processing, advertising and prominence, product analysis, and payment.info:eu-repo/semantics/publishedVersio

Semantic discovery and reuse of business process patterns

Patterns currently play an important role in modern information systems (IS) development and their use has mainly been restricted to the design and implementation phases of the development lifecycle. Given the increasing significance of business modelling in IS development, patterns have the potential of providing a viable solution for promoting reusability of recurrent generalized models in the very early stages of development. As a statement of research-in-progress this paper focuses on business process patterns and proposes an initial methodological framework for the discovery and reuse of business process patterns within the IS development lifecycle. The framework borrows ideas from the domain engineering literature and proposes the use of semantics to drive both the discovery of patterns as well as their reuse

Funcionalidades essenciais na presença comercial na internet

O sucesso da presença comercial na internet de uma empresa é fortemente afetado pelas funcionalidades que possui. Com o aumento do número de websites disponíveis, a possibilidade de escolha dos consumidores é agora mais vasta, originando novos desafios às empresas no que concerne à atração e retenção dos consumidores online. A implementação equilibrada de funcionalidades dentro da presença comercial na internet é importante, não só devido complexidade e à carga cognitiva requerida na sua utilização, mas também devido a razões financeiras. Investir dinheiro (por exemplo, na aquisição de módulos de software, tempo de programação, manutenção e atualização, etc.) em funcionalidades que não são valorizadas pelos consumidores online, não parece uma afetação eficiente de recursos, especialmente quando estes são escassos, situação essa que corresponde a muitas pequenas empresas que operam na internet. No entanto, a literatura oferece pouca ajuda aos gestores para decidirem que funcionalidades devem ser implementadas, de acordo com uma base racional. Dentro deste contexto, pretendeu-se preencher com este trabalho a lacuna entre a revisão da literatura e a necessidade de ajudar na escolha das funcionalidades adequadas para implementar uma presença comercial na internet. Através deste trabalho identificaram-se 16 funcionalidades essenciais que devem ser implementadas, estando estas agrupadas em quatro conjuntos: processamento das encomendas; publicidade e destaque; análise de produtos; e pagamento tradicional.The success of a commercial internet presence is strongly affected by its functionalities.

Λογισμικό ανοιχτού κώδικα: διοίκηση, διάχυση και ανταγωνισμός

Στόχος της διατριβής είναι να συνεισφέρει στην έρευνα για το ανοιχτό λογισμικό μέσα από τη μελέτη της διάχυσής του, αλλά και των επιδράσεών της. Η έρευνα εστιάζει στην πορεία της διάχυσης μέσα στο χρόνο και προσδιορίζει και αποτιμά σχέσεις αιτίας και αποτελέσματος του φαινομένου. Αφενός, προσδιορίζονται και αποτιμούνται οι παράγοντες που επηρεάζουν την πορεία διάχυσης και τη βιωσιμότητα του ανοιχτού λογισμικού (σχέσεις αιτίας). Αφετέρου, μελετώνται οι επιπτώσεις (σχέσεις αποτελέσματος) της διάχυσης τόσο σε οικονομικό, όσο και σε κοινωνικο-πολιτικό επίπεδο. Στο οικονομικό επίπεδο, πραγματοποιείται ανάλυση της αγοράς λογισμικού και εξετάζεται η συμπεριφορά και η δομή της ως αποτέλεσμα όχι μόνο της εισόδου του ανοιχτού λογισμικού, αλλά και των επιχειρηματικών μοντέλων ανοιχτού λογισμικού. Στο κοινωνικό-πολιτικό επίπεδο μελετώνται οι επιδράσεις στο δημόσιο τομέα και ιδιαίτερα στην ηλεκτρονική διακυβέρνηση και εκπαίδευση. Οι προτεινόμενες μεθοδολογίες και μοντέλα, βασίζονται στις θεωρίες διάχυσης των καινοτομιών και αποδοχής των Πληροφοριακών Συστημάτων, αλλά και σε κοινωνικο-οικονομικέ θεωρίες. Η αποτίμηση των μοντέλων υλοποιείται με αυστηρό μεθοδολογικό πλαίσιο των μαθηματικών και της στατιστικής. Τα αποτελέσματα της έρευνας παρέχουν ακριβείς, a-priori εκτιμήσεις της πορείας διάχυσης, του ανταγωνισμού και των σημείων ισορροπίας της αγοράς και μπορεί να αποβούν πολύ χρήσιμες σε ένα διαρκώς εξελισσόμενο και ανταγωνιστικό περιβάλλον, όπως αυτό της αγοράς ΤΠΕ.This PhD thesis aims to contribute to the open source software (OSS) research by studying the OSS diffusion and its economic, social and political implications. The research focuses on the process of diffusion over time and assesses relations of cause and effect. Firstly, it identifies and assesses the factors critical for the diffusion and sustainability of OSS (cause). Secondly, it assesses the economic and socio-political impact of the OSS diffusion (effect). An analysis of the software market and a deeper examination of the market behavior and structure is performed, as a result of both the OSS diffusion and its implications, that is the new OSS business models. In socio-political terms, the effects of OSS diffusion in the sectors of eGovernment and education are studied. The proposed models and methodologies are based on theoretical background that borrows elements from the theories of technology acceptance and diffusion of innovations, as well as from social and economic theories. The models’ evaluation is implemented with a rigorous methodological framework of mathematics and statistics. Results provide more accurate, a-priori estimations of the diffusion rate and the market competition and equilibrium tthatare especially helpful in a continuously evolving and competitive environment such as the ICT market
