The impact of Brexit on the legal framework for cross-border corporate activity

The extent of the legal impact of the withdrawal of the UK from the EU on cross-border corporate activities, transactions and investment will depend on whether the UK remains part of the European Economic Area. If the UK leaves the EEA, it will be more difficult for UK companies, and in particular for financial sector firms, to do business and expand in the EEA either by acquisitions or by establishing subsidiaries and branches. In parallel, it would be more difficult for the UK to attract investment by EEA companies and investors. Furthermore, the preeminent position of London as a major global financial centre would be challenged due to the combined effect of two factors: (a) it would be more difficult for UK and EEA companies to offer their securities to investors across the EEA; and (b) selecting the UK as the country of incorporation either of the top holding company of an internationally active corporate group or of the main European arm of such a group would be less attractive. Maintaining full access to the Single Market is thus crucial for the UK econom

Uncertain Reasoning in Justification Logic

This thesis studies the combination of two well known formal systems for knowledge representation: probabilistic logic and justification logic. Our aim is to design a formal framework that allows the analysis of epistemic situations with incomplete information. In order to achieve this we introduce two probabilistic justification logics, which are defined by adding probability operators to the minimal justification logic J. We prove soundness and completeness theorems for our logics and establish decidability procedures. Both our logics rely on an infinitary rule so that strong completeness can be achieved. One of the most interesting mathematical results for our logics is the fact that adding only one iteration of the probability operator to the justification logic J does not increase the computational complexity of the logic

Improvement Axons for Ardas Cultural Festival in Evros, Greece, based on attendees perceptions

Festivals provide not only the hosting community but the wider destination area as well, with many benefits. In consequence they have gained increasing attention in the prism of tourism growth. The most popular festival in Evros prefecture in the Thrace region (Northern Greece) is Ardas festival which takes place annually near the banks of the Ardas River and is known as “Festival Arda: youth gathering”. In the highly competitive tourism market, festival organizers need to keep their customers satisfied in order to maintain and increase their market share. To accomplish this task, festival organizers must understand the visitors’ behaviour and intentions and formulate their strategy accordingly. In this context, this study aims to examine the current status of Ardas Festival based on attendees perceptions and, secondly to propose a segmentation of the attendees market, based on their overall visiting experience as well as the degree of their satisfaction. quantitative research study was conducted on the premises of Ardas festival .The questionnaire developed specifically for this purpose. It includes the following areas of improvement which were generated based on a prior qualitative study. The quantitative research obtained a sample of 410 visitors attending the festival. Statistical analysis included classical descriptive analysis, cluster analysis, and cross-tabulation tests. Results showed that all statements were considered important for attendees of the festival (MS>3.51), with cleanness being the most important (MS=4.53) and the increase of the number of Balkan countries bands the least (MS= 3.62). Three clusters (n1=116; n2=146; n3=140) were produced based on the points of development as well as visitors’ satisfaction and impression. Results also showed that clusters were statistically significantly different regarding gender, marital status, education, occupation, and net individual monthly income. Results of the research can be a valuable input for the Ardas festival organizers. The findings can contribute to the success of the festival by satisfying the visitors and consequently increasing retention rate and loyaltyFestival, tourism, destination marketing, improvement axons, consumer’s behaviour, marketing, Greece

An examination of the appropriateness of the contemporary strategic management models for the Greek small manufacturing enterprises

The starting point of the project was the observation that strategic management is absent in small businesses. The first objective of the project was to examine the reasons causing this situation in Greece, the second one, to examine the appropriateness of the contemporary models of strategic planning for the Greek S.M.E.s, and the third to examine the appropriateness of the alternative approaches to strategic management for the Greek S.M.E.s. The term appropriateness includes (a) the ability of managers to use the models and (b) the ability of the models to assist the managers. The results of the research indicate that none of the two above conditions exists, hence, it is suggested that the contemporary models of strategic management are inappropriate for the Greek S.M.E.s. Many previous research projects on the topic suggest that since the strategic decision making process in S.M.E.s is informal, the whole process is absent or ineffective. Current trends in S.M.E.s' strategic management do not consider the informality of the strategic decision making process as a kind of managerial illness, but as a managerial characteristic. The use of sophisticated data collection and analytical methods does not indicate successful strategic decisions, but it indicates the method large firms use to manage their strategy. According to the literature review, the S.M.E.s' managers avoid the use of the contemporary models of strategic management, because they do not have the knowledge, the resources or the time. Another thesis, expressed by some firms' specialists, suggests that small firms are different from large ones, hence their practice of strategic management should not follow the large firm's prototypes

Dynamic Complexity Meets Parameterised Algorithms

Dynamic Complexity studies the maintainability of queries with logical formulas in a setting where the underlying structure or database changes over time. Most often, these formulas are from first-order logic, giving rise to the dynamic complexity class DynFO. This paper investigates extensions of DynFO in the spirit of parameterised algorithms. In this setting structures come with a parameter k and the extensions allow additional "space" of size f(k) (in the form of an additional structure of this size) or additional time f(k) (in the form of iterations of formulas) or both. The resulting classes are compared with their non-dynamic counterparts and other classes. The main part of the paper explores the applicability of methods for parameterised algorithms to this setting through case studies for various well-known parameterised problems

Probabilistic justification logic

We present a probabilistic justification logic, PPJ⁠, as a framework for uncertain reasoning about rational belief, degrees of belief and justifications. We establish soundness and strong completeness for PPJ with respect to the class of so-called measurable Kripke-like models and show that the satisfiability problem is decidable. We discuss how PPJ provides insight into the well-known lottery paradox
