Autori: Gaeta, Angelo
Abstract: Current threats, such as terrorism and cyber-terrorism, pose new challenges to security and defence
communities, and the ability to reason with different perspectives and detecting connections between facts,
relationships and events becomes crucial to address these challenges. To this purpose, a less procedural and
standardized approach is useful, able to leverage current computational and artificial intelligence
technologies to detect threats and protect physical and cyber-physical systems. This raises a strong interest
in defining and adopting new methods and techniques that, to a certain extent, are such as to replicate, or
at least to support, human cognitive processes. If we consider the "creativity" behind some recent attacks,
such as that one of 09/11/2001, we can understand the need to rethink security in situational rather than
procedural terms, and this has an important implication that helps to frame the problem and research
objectives of this thesis. This implication is a shift from being aware of what we need to prevent (and the
related rules and procedures to that end) to gaining greater awareness of what might happen. From this
consideration, it emerges the need of methods and tools that support decision makers in their ability to carry
out analyses that allow to hypothesize different threat scenarios, and to reason about their evolutions. This
is, essentially, the main objective of the so-called intelligence activities.
The research problem investigated in the Ph.D period is how to improve the awareness of analysts and
decision makers in the early stages of an intelligence analysis to prevent intentional attacks, and the specific
objectives concern the definition and validation of reasoning methods based on Granular Computing (GrC)
for this purpose. ... [edited by Author]

Autori: Capolupo, Nicola
Abstract: This research aims to read and examine territories from an organizational point of view, focusing on
the demands and challenges that they daily face and are called to face. In particular, it intends to focus
on what represents the pivotal concept of Niklas Luhmann's Theory of Social Systems, i.e.
communication: organizations are social systems (decision-making machines) that process
information, which is always new and different, despite their polarity. Through the communicative
act, each organization reproduces its strategic choices and / or the environment, within which the
organization lives and reproduces itself (the society as a complex system). The luhmannian
organizational autopoiesis is, in fact, allowed by the organization's capability to communicate itself
externally; in this sense communication assumes a fundamental role for the organization (and, in this
case, for the territory and the creation of its Destination Image). The research methodology chosen to
analyze and demonstrate these phenomena will therefore be divided into several moments: initially,
it consists on a survey including the opinion of students from the University of Salerno, measuring
the target’s predisposition to use social media to promote and reporting security issues relating to the
territory; in addition, the experimentation of a communication model based on the study of digital
language coding, in collaboration with the personnel of selected Campania Public Administrations,
between institutions / territories and citizenship; finally, the organization of a focus group divided
into two stages, to understand the efficacy of the aforementioned model and its specific application
for each entity. The aims of its development are, in fact, oriented to eliminate communication
boundaries between P.A. and citizenship, and the establishment of an interactive system where all
actors interact at the same level and co-produce value. [edited by Author]

Autori: Maione, Gennaro
Abstract: Objective: The thesis focuses on the concept of Open Government Data (OGD) as a new approach to the management of public administrations (Pereira et al., 2017; Wang and Lo, 2016; Zuiderwijk and Janssen, 2014; Attard et al., 2015; Chan, 2013), based on the use of technologies for data treatment capable of favoring the affirmation of logics characterized by transparency, citizens’ involvement and participation in the processes, activities and services of the public sector (Dawes et al., 2016; Gonzalez-Zapata and Heeks, 2015; Ubaldi, 2013; Shadbolt et al., 2012). In particular, the objective of the work is to deepen the aspects and conditions enabling the management of Public Administration (PA) according to the OGD, as well as the impact of this approach on the quality of the public service provided to the community. The choice to carry out this study arises from the consideration according to which in literature, to date, there is no organic nucleus of empirical research aimed at investigating the stimulating factors of the ODG and the concrete effects on the public service quality resulting from the implementation of such an approach in public administrations.
Methodology: The work starts from the analysis of the state of the art dedicated to the methods of conducting public administrations. Specifically, through a chronological excursus, the main approaches to the management of the PA (such as the Bureaucratic Model, New Public Management, New Public Governance, New Public Service, Open Government) were analyzed to represent the paradigmatic evolution leading to the affirmation of the OGD. The most important aspects (constructs) emerging from the analysis of the literature were further investigated to verify the existence of possible relations of influence between them. To this end, for each of the identified constructs, several items were selected for the construction of a questionnaire, administered to a sample of 567 Italian citizens. The results emerged from the answers provided by the citizens allowed defining and testing a Structural Equation Model (SEM), aimed at providing empirical evidences about the facilitating aspects of the OGD and the effects of its adoption within the PA in terms of public service quality for the community.
Results: The findings highlight the existence of some crucial aspects, sometimes undervalued within the PA, which should be taken into account for the proper management of public administrations according to the logic of the OGD, especially in a historical moment characterized by an increasingly felt need to manage huge amounts of data in a transparent, participatory and collaborative way. In particular, according to the results of the analysis, it is necessary to encourage the dissemination of data-driven culture at every level of society so that citizens can take advantage of the benefits deriving from a thoughtful adoption of the ODG in the PA.
Implications: The work provides both theoretical and managerial implications. From a purely theoretical point of view, the thesis offers its contribution under a twofold profile: methodological and conceptual. Regarding the first aspect, the study brings to light the results obtained by testing a SEM, which represents a methodology particularly appreciated for the analysis of data in the social sciences (Hair et al., 2016; Kline, 2015), especially since it allows verifying the interrelations between latent (not directly measurable) variables (Heck and Thomas, 2015; Duncan, 2014); with regard to the conceptual profile, the thesis favors the enrichment of the literature through the analysis of an approach to company management in a sector in which the studies in this regard are still fragmented. Regarding managerial implications, the identification of the most incisive aspects in managing public administration according to the Open Government Data provides policy makers and public sector executives with valuable information for the development of policies and strategies capable of improving the quality of the service rendered to citizens. In particular, the usefulness of the thesis should be seen in the fact that, through an empirical analysis, the work offers ideas to optimize the allocation of human, economic, technological and temporal resources. In other words, in presence of limited resources, as traditionally occurs in the public sector, knowing the aspects toward which investment should be opportunely directed could generate a considerable advantage for public domain services’ recipients.
Research limitations: The study follows a quantitative approach based on the test of a Structural Equation Model, defined through the administration of questionnaires. The choice to resort to questionnaires, if on the one hand allowed building a large sample (made up of over 500 citizens), on the other hand reduced the depth of the analysis, since it prevented from investigating with high degree of detail the thought of each citizen involved in the sample survey. For this reason, the thesis takes shape as a starting point for a future research project to be carried out by using additional qualitative and quantitative methods, to be applied by means of both traditional (such as interviews) and innovative (such as social media analytics) techniques.

Autori: Grimaldi, Mara
Abstract: The study proposes the adoption of a synthesis view to the exploration of value co-creation according to a “meta”- ecosystems perspective that takes into account the theoretical and epistemological complexity of the construct. A conceptual framework is proposed to investigate the generation of the deep mechanisms of co-creation through the introduction of its semantic categorization. After a discussion on the epistemological issues (the possibilities and limitations of an operationalization of value co-creation), the concept is subdivided into three sub-processes, Value-in-exchange, Value-in-use, Value -in-context, connected respectively to the three contexts identified in ecosystems research, Micro, Meso and Macro. For each dimension, three criteria or sub-dimensions are proposed to specify the variations of co-creation in the different contexts: 1) activity; 2) relational modalities; 3) object of the exchange. Then, the framework is validated conceptually by a sample of experts through the Delphi technique. Some sub-dimensions were eliminated or replaced with “labels” that have been considered more suitable. The most relevant changes in the framework are: 1) the association between the three classification criteria (activities, relational modalities and object of exchange) and the meta-level; 2) the replacing of the category “objects of exchange”, with the most common category of “resources”; 3) the conceptual specification of co-delivery (meso-level) and meaning (macro-level). The introduction of a framework that classifies the potential co-creation activities performed by users in the various ecosystem contexts can produce advancements in marketing and service management research in which previous studies address the complex issue only from a theoretical point of view. Furthermore, a classification of the various manifestations that make co-creation observable can help managers understand: 1) how to manage the process strategically from the early stages of delivery (co-design); 2) how to stimulate involvement and collaboration in each step (co-delivery and post-delivery); 3) how to monitor any problems in service delivery or prevent possible co-destruction behaviors.
