Teoria dei giochi e Multi-criteria decision-making per reti mobili Ad-hoc: un protocollo di routing

Nell'elaborato si analizzano aspetti della teoria dei giochi e della multi-criteria decision-making. La riflessione serve a proporre le basi per un nuovo modello di protocollo di routing in ambito Mobile Ad-hoc Networks. Questo prototipo mira a generare una rete che riesca a gestirsi in maniera ottimale grazie ad un'acuta tecnica di clusterizzazione. Allo stesso tempo si propone come obiettivo il risparmio energetico e la partecipazione collaborativa di tutti i componenti.

Strategic decision making in international firms: effect of top management team internationalization on international strategic decision process

In this research project, I have integrated two research streams on international strategic decisions making in international firms: upper echelons or top management teams (TMT) internationalization research and international strategic decision making process research. Both research streams in international business literature have evolved independently, but there is a potential in combining these two streams of research. The first empirical paper “TMT internationalization and international strategic decision making process: a decision level analysis of rationality, speed, and performance” explores the influence of TMT internationalization on strategic decision rationality and speed and, subsequently, their effect on international strategic decision effectiveness (performance). The results show that the internationalization of TMT is positively related to decision effectiveness and this relationship is mediated by decision rationality while the hypotheses regarding the association between TMT internationalization and decision speed, and the mediating effect of speed were not supported. The second paper “TMT internationalization and international strategic decision rationality: the mediating role of international information” of my thesis is a simple but logical extension of first paper. The first paper showed that TMT Internationalization has a significant positive effect on international strategic decision rationality. The second paper explicitly showed that TMT internationalization affect on international strategic decision rationality comes from two sources: international experience (personal international knowledge and information) and international information collected from managerial international contacts. For this research project, I have collected data from international software firms in Pakistan. My research contributes to the literature on upper echelons theory and strategic decision making in context of international business and international firms by explicitly examining the link between TMT internationalization and characteristics of strategic decisions making process (i.e. rationality and speed) in international firms and their possible mediating effect on performance.

Decision making nella robotica collettiva

Nel testo viene esposta la presa di decisione nella robotica collettiva, cioè il comportamento collettivo esibito dagli animali sociali in sciame migrato in un gruppo di robot. Questa tesi si prefigge di analizzare come un insieme di individui, all'interno di un gruppo, possano giungere tutti ad avere una stessa opinione comune, o come essi siano in grado di dividersi autonomamente il lavoro senza alcun bisogno di controllo centrale. Inizialmente, viene introdotta la robotica collettiva, esponendone origini, caratteristiche e ambiti di ricerca. Viene in seguito presentato il collective decision making, all'interno del comportamento collettivo generale, esponendone le origini biologiche fino ai primi esperimenti su dei semplici robot. Vengono poi analizzati i due aspetti del decision making, vale a dire il raggiungimento del consenso e la suddivisione del lavoro. Per entrambi gli argomenti, sono presentati studi sia di carattere biologico che robotico, allo scopo di trarne similitudini e differenze e realizzare una valida analisi critica. Infine, vengono esposti i possibili sviluppi del comportamento e della robotica collettiva, mostrando possibili scenari di utilizzo futuro e gli attuali limiti allo sviluppo.

[Molecular analyses for (early) recognition of hematologic diseases - sense and sensibility for molecular analysis: the art of intelligent decision-making]

During the last 10 years several molecular markers have been established as useful tools among the armamentarium of a hematologist. As a consequence, the number of performed hematologic molecular analyses has immensely increased. Often, such tests replace or complement other laboratory methods. Molecular markers can be useful in many ways: they can serve for diagnostics, describe the prognostic profile, predict which types of drugs are indicated, and can be used for the therapeutic monitoring of the patient to indicate an adequate response or predict resistance or relapse of the disease. Many markers fulfill more than one of these aspects. Most important, however, is the right choice of analyses at the right time-points!

European Union Trade Policy after Enlargement: Larger Crowds, Shifting Priorities and Informal Decision-Making

The article focuses on the effects of Eastern enlargement on EU trade policy-making. On interest constellation, the article makes a case that protectionist forces have been strengthened relative to liberal forces. This slight protectionist turn is mostly witnessed in the area of anti-dumping and with respect to the Doha trade round. On preference aggregation, guided by a principal–agent framework, it is argued that the growth in the number of actors (principals and interest groups) has not constrained the role of the European Commission (agent). However, it has led to an increase in informal processes and has empowered large trading nations vis-a`-vis smaller and less ‘comitology-experienced’ member states.
