This paper introduces the Mobile Process Landscaping (MPL) method for modelling, analysing and improving mobile business processes. Current approaches for process modelling and analysis do not explicitly allow the consideration of typical mobility issues, e.g. location-dependent activities, mobile networks as resources and specifics of mobile information systems. Thus, our method focuses on the modelling and analysis of these characteristics, and is furthermore based on the process landscaping approach, supporting the easy creation of hierarchical models of distributed processes. The method comes with a specialized modelling notation and guidelines for the creation of process landscapes, context models, and business object models. Furthermore, it provides a catalogue of formally defined evaluation objectives, targeting at typical mobility issues. Each evaluation objective can automatically be tested on the created process landscape. Furthermore, the method includes a best practices catalogue with patterns for process and application improvements for typical mobility situations. A validation of the method is presented showing results from the method’s use in a real-world project.

A Ética Nicomaqueia tem como tema central a felicidade (eudaimonia). No entanto, há um problema, pelo menos aparente, em relação a como a eudaimonia é caracterizada principalmente no livro I e no livro X da EN. A partir do que é desenvolvido no primeiro livro e nos livros centrais da EN, podemos entender que a felicidade contém boas ações, isto é, ações de acordo com as virtudes de caráter. No entanto, no livro X, a felicidade é identificada com a contemplação, ou seja, o exercício da virtude teórica, e as ações moralmente virtuosas acabam ficando em uma posição inferior. Surge, então, o problema de determinar se a felicidade é um ou mais bens e como combiná-los. Esse problema foi apontado por W. F. R. Hardie no artigo “O bem final na ética de Aristóteles” e, a partir de sua publicação, iniciou-se uma discussão a respeito de a eudaimonia ser um fim inclusivo ou um fim dominante. O objetivo deste trabalho é investigar a noção de eudaimonia na EN a partir da discussão mencionada acima. Para isso, analiso as passagens e os conceitos importantes para avaliar os argumentos apresentados e as interpretações sustentadas pelos comentadores inseridos nessa discussão. Ao longo do trabalho, mostro que a identificação da eudaimonia com a atividade teórica virtuosa não é incompatível com o exercício das virtudes morais e que ambos fazem parte da eudaimonia. / The central theme of the Nicomachean Ethics is happiness (eudaimonia). However there is a problem, at least apparent, regarding the characterization of eudaimonia, particulary in books I and X of the NE. Based on what is developed in the first and central books of NE we can understand that happiness contains good actions, that is, actions in accordance with character virtues. In book X, however, happiness is identified with contemplation, that is, the exercise of theorethical virtue, and morally virtuous actions ends up occupying a lower position. What follows is the emergence of the problem of determining whether happiness is one or more goods and how to combine them. This problem was pointed out by W. F. R. Hardie in the paper “The final good in Aristotle's Ethics”, and since its publication, it started a discussion about eudaimonia being an inclusive or a dominant end. The aim of this work is to study the idea of eudaimonia in the NE based on the discussion mentioned above. To achieve that, I analyze important passages and concepts to assess the arguments presented and the interpretations sustained by critics involved in the discussion. In this study, I show that the identification of eudaimonia with theorethical activity is not inconsistent with the exercise of moral virtues, and that both are part of eudaimonia.

Στις μέρες μας η ευρυζωνικότητα έχει σπουδαίο ρόλο στη ζωή μας. Πιο αναλυτικά η ευρυζωνικότητα μας προσφέρει υπηρεσίες και πολλά οφέλη στην καθημερινή μας ζωή. Για παράδειγμα το internet, μας προσφέρει πολλές υπηρεσίες όπως email, τηλεσύνδεση και αλλά πολλά καθώς και μεταφορά μεγάλου όγκου πληροφοριών. Οι βασικές προϋποθέσεις για την ανάπτυξη της ευρυζωνικότητας είναι η ανάπτυξη υποδομών, η ανάπτυξη υπηρεσιών και η μείωση του «ψηφιακού χάσματος». Όλα τα παραπάνω είναι συνδεδεμένα με τις τεχνολογίες που θα υλοποιήσουν αυτές τις προδιαγραφές. Αυτές δεν είναι άλλες από τις ενσύρματες (ADSL, BPL συστήματα και οπτικές ίνες) και ασύρματες τεχνολογίες (wifi, wimax, δορυφορικές επικοινωνίες) καθώς και συνδυασμό αυτών τον δύο. Δηλαδή αυτές οι τεχνολογίες είναι υπεύθυνες για την παροχή ευρυζωνικών υπηρεσιών στον πελάτη. Σκοπός της παρούσας διπλωματικής είναι να μπορέσει να δώσει στον αναγνώστη μια σφαιρική άποψη για κάθε τεχνολογία παροχής ευρυζωνικών υπηρεσιών και να μπορέσει να εξοικειωθεί με αυτές τις τεχνολογίες. Ο αναγνώστης πληροφορείται ποιες τεχνολογίες θα του προσφέρουν υψηλότερες ταχύτητες μετάδοσης δεδομένων καθώς και τα πλεονεκτήματα και μειονεκτήματα της κάθε τεχνολογίας. Επίσης σκοπός της διπλωματικής αυτής είναι να επισημάνει τις παραμέτρους που επηρεάζουν την κάθε τεχνολογία ως προς την απόδοση που έχει και ως προς τις ταχύτητες που προσφέρει προς τον συνδρομητή. Τέλος η διπλωματική αυτή δίνει στον αναγνώστη και κάποια οικονομικά στοιχεία έτσι ώστε να μπορεί να αντιληφθεί το οικονομικό κόστος που μπορεί να έχει η κάθε τεχνολογία καθώς και τους μελλοντικούς στόχους που έχει η κάθε τεχνολογία σύμφωνα πάντα με τον οικονομικό σχεδιασμό που έχει κάνει. / Nowadays, broadband transmission plays an important role in our lives. Particularly, broadband transmission provides us with many kinds of broadband services and various benefits in our daily life. For example, internet provides us with many services such as e-mail, teleconferencing and other kinds of prospects and capabilities such as the transfer of big amounts of information and bytes. The basic prerequisites which are necessary for the development of broadband transmission are the existence of broadband infrastructure, the advancement of broadband services and last but not least bridging the gap between binary and analogue technology. All above are related to the technologies that will carry out these standards. And these technologies combine both wire technologies (such as ADSL, BPL systems and optic fibers) and wireless technologies (wifi, wimax and satellite communications). Sometimes these two kinds of technologies cooperate at the same time constructively. In conclusion, these technologies are responsible for providing consumers with the various broadband services. This project has the intention of giving us and generally speaking, giving readers a manifold view of every technology that provides us with broadband services and also helping us to become familiars with it. In addition to this, the reader is informed as for which technologies are able to provide him with fast bit rates and at the same time he has the opportunity to see the advantages and disadvantages of each technology. Furthermore, the main purpose of that project is to call to attention the factors that affect each technology as far as the bit and byte rates that are provided to consumers are concerned. In a nutshell, this project gives to the reader some financial and economic data so as to be able to understand the financial cost of each technology and at the same time the forward targets and goals of it according to the economic planning that has been made for that technology particularly.

Aristóteles é considerado um precursor do problema da vontade livre. Apesar disto, ele é também considerado por muitos de seus intérpretes ou um determinista, alguém que negou precisamente a liberdade da vontade, e um compatibilista, isto é, alguém que procurou compatibilizar o determinismo com a responsabilização ou um autor que iniciou a discussão, mas que não tinha muita clareza sobre o problema, pois este não apareceria com toda a sua força senão após os desenvolvimentos da filosofia estóica. Esta tese pretende responder a ambas estas interpretações. Para isso, é feita uma análise das passagens em que Aristóteles trata da responsabilização moral, na Ética Eudêmia II.6-11 e na Ética Nicomaquéia III.1-7. O objetivo é mostrar que sua teoria da responsabilização moral não é apenas incompatível com o determinismo da vontade, e, portanto, ele não pode ser um compatibilista, mas que a sua teoria dos atos voluntários humanos é coerente com isso, ou seja, ele produziu uma teoria dos princípios das ações que é indeterminista. Aristóteles pode assim ser considerado como tendo definido, sem confusões, o que significa para a ‘vontade’ ser livre, mesmo que ele não tenha se valido e nem definido o termo ‘vontade’. Ele não faz uso deste termo, porque tem outro termo que cumpre esta função: ‘escolha deliberada’. Aristóteles, portanto, defende uma tese da escolha livre que é necessária para sua teoria da responsabilização moral não compatibilista. / Aristotle is taken to be a precursor to the ‘free-will’ problem. In spite of that, he is considered also by many scholars to be either a determinist, someone who deny the freedom of the will, and a compatibilist, someone who tried to make cohere determinism and responsibility, or an author that begun this discussion, but did not have much clarity about it, because this would have to wait the developments of the Stoic School, in Antiquity. This thesis answers both these interpretations. To accomplish this, an analysis of the passages in which Aristotle deals with moral responsibility is done, in the Eudemian Ethics II.6-11 and in the Nicomachean Ethics III.1-7. The goal is to show that his theory of responsibility is not compatible with determinism of the will and, therefore, he cannot be sustained a compatibilist, and that his theory about voluntary acts is consistent with it: he left an indeterminist theory of the principles of actions. That is why Aristotle can be taken to have answered, without any confusions, what means to the ‘will’ to be ‘free’, even though he has not used the term, ‘will’. He does not use this term, because he has another one that can play this role: deliberate choice. Aristotle, therefore, claims that free choice is necessary to his incompatibilist theory of responsibility.

En la lectura de la Ética a Nicómaco se evidencia un tópico recurrente: el placer. En la presente, se examina la naturaleza del placer y su relación con la felicidad en dicha obra. Luego, la reflexión ética se complementa con una reflexión psicológica sobre un principio cuyo objeto es el placer: el principio pollyanna. Después, se muestra la insuficiencia de los dos argumentos utilizados por Aristóteles para refutar que el placer sea el bien supremo. Entonces, se presenta el argumento de la Máquina del Placer para refutar dicha tesis. Finalmente, se expone uno de los límites del placer: el sentido. / Tesis
