Seguridad comunitaria y el rol de la policía

Se desarrolla un marco teórico de la seguridad comunitaria al definirla a partir de la evolución que ha tenido el tema de la seguridad comunitaria a partir de la adopción del enfoque más amplio de la seguridad humana de los habitantes como base y eje de las políticas públicas, de donde nace un nuevo conjunto de prioridades para la erradicación de los factores de riesgo social asociados o que son proclives a la violencia y la comisión de delitos, tales como la deserción escolar, el desempleo, la violencia en todas sus formas, la inequidad de género y diversidad social, la falta de cohesión social, las migraciones, internas o externas, forzadas por las condiciones de vida. El enfoque se basa en un nuevo modelo criminológico que está sustentado en el marco de los derechos humanos, la seguridad humana y el modelo de control social democrático para formar un modelo de desarrollo humano sostenible, por tanto la prevención sustentada en políticas públicas para la seguridad humana, la participación comunitaria y el nuevo rol de la policía comunitaria.It develops a theoretical framework for defining the community from the developments that have taken the issue of community safety from the adoption of the broader approach to human security of people as the basis and focus of public policy, arises where a new set of priorities for the eradication of social risk factors that are associated with or prone to violence and committing crimes, such as school dropouts, unemployment, violence in all its forms, gender inequity and social diversity, lack of social cohesion, migration, internal or external, forced by the conditions of life. The approach is based on a new criminological model that is based on the framework of human rights, human security and control model to form a social democratic model of sustainable human development, thus preventing sustained public policies for security human, community involvement and the new role of community police.

Optimal bidding strategies of an electric vehicle aggregator in an electricity market

In recent years Electric Vehicles (EVs) are getting more importance as future transport systems, due to the increase of the concerns relevant to the greenhouse gases emission and the use fossil fuel. The management of the charging and discharging process of EVs could provide new business model for participating in the electricity markets. Moreover, vehicle to grid systems have the potential of increasing utility system flexibility. This thesis develops some models for the optimal integration of the EVs in the electricity market. In particular, the thesis focuses on the optimal bidding strategy of an EV aggregator participating to both the day ahead market and the secondary reserve market. The aggregator profit is maximized taking into account the energy balance equation, as well as the technical constraints of energy settlement, power supply and state of charge of the EVs. The results obtained by using the GAMS (General Algebraic Modelling System) environment are presented and discussed.

Development of a framework for the analysis of document-based phishing campaigns

In questo elaborato di tesi si affronta lo sviluppo di un framework per l'analisi di URL di phishing estratte da documenti malevoli. Tramite il linguaggio python3 e browsers automatizzati si è sviluppata una pipeline per analizzare queste campagne malevole. La pipeline ha lo scopo di arrivare alla pagina finale, evitando di essere bloccata da tecniche anti-bot di cloaking, per catturare una schermata e salvare la pagina in locale. Durante l'analisi tutto il traffico è salvato per analisi future. Ad ogni URL visitato vengono salvate informazioni quali entry DNS, codice di Autonomous System e lo stato nella blocklist di Google. Un'analisi iniziale delle due campagne più estese è stata effettuata, rivelando il business model dietro ad esse e le tecniche usate per proteggere l'infrastruttura stessa.

L'applicazione usata come caso di studio è "LetsBox!", un'applicazione mobile della categoria puzzle game, sviluppata sfruttando il framework di sviluppo di app ibride IONIC 5, con l’obiettivo di creare un gioco che coinvolgesse il giocatore tanto da farlo giocare nei suoi momenti di svago e indurlo a sfidare i record esistenti ma, nello stesso tempo creare un gioco originale e non esistente sul mercato.

Sviluppare le competenze trasversali tra gli studenti: progettazione di un MINOR “Be Entrepreneurial Aware STudent – BE(A)ST"

La volontà da parte degli studenti di acquisire maggiore consapevolezza rispetto ai loro interessi, da poter sfruttare nel percorso professionale post-laurea, non riesce a trovare fondamento all’interno di percorsi di apprendimento preconfezionati. Attraverso l’analisi delle esigenze degli studenti, la loro profilazione in personas e l’analisi del contesto imprenditoriale, nello specifico all’interno dell’ecosistema delle StartUp, l’elaborato propone la progettazione di un minor in entrepreneurship presso l’Alma Mater Studiorum – Università di Bologna, offrendo una modalità di implementazione di supporto per gli stessi scopi all’interno di altri Atenei, fornendo un metodo e delle linee guida di supporto al progettista. Fondamentali strumenti per l’analisi e la progettazione sono stati il Design Thinking e il Personal Business Model Canvas.

Job satisfaction and life satisfaction: Analysis of a reciprocal model with social demographic moderators

The general objective of the study was to empirically test a reciprocal model of job satisfaction and life satisfaction while controlling for some social demographic variables. 827 employees working in 34 car dealerships in Northern Quebec (56% responses rate) were surveyed. The multiple item questionnaires were analysed using correlation analysis, chi square and ANOVAs. Results show interesting patterns emerging for the relationships between job and life satisfaction of which 49.2% of all individuals have spillover, 43.5% compensation, and 7.3% segmentation type of relationships. Results, nonetheless, are far richer and the model becomes much more refined when social demographic indicators are taken into account. Globally, social demographic variables demonstrate some effects on each satisfaction individually but also on the interrelation (nature of the relations) between life and work satisfaction.

Designing persuasive third party applications for social networking services based on the 3D-RAB model

The use of social networks services for promoting business, teaching, learning, persuasion and spread of information continues to attract attention as most social networking services (SNSs) now allow third party applications to operate on their sites. In the field of persuasive technology, the ability of SNSs to build relationships among their users and create momentum and enthusiasm through rapid cycles also give it a greater advantage over other persuasive technology approaches. In this paper we discuss the 3-dimensional relationship between attitude and behavior (3D-RAB) model, and demonstrate how it can be used in designing third-party persuasive applications in SNSs by considering external factors which affects persuasive strategies.

Closed-loop feedback computation model of dynamical reputation based on the local trust evaluation in business-to-consumer e-commerce

Trust and reputation are important factors that influence the success of both traditional transactions in physical social networks and modern e-commerce in virtual Internet environments. It is difficult to define the concept of trust and quantify it because trust has both subjective and objective characteristics at the same time. A well-reported issue with reputation management system in business-to-consumer (BtoC) e-commerce is the “all good reputation” problem. In order to deal with the confusion, a new computational model of reputation is proposed in this paper. The ratings of each customer are set as basic trust score events. In addition, the time series of massive ratings are aggregated to formulate the sellers’ local temporal trust scores by Beta distribution. A logical model of trust and reputation is established based on the analysis of the dynamical relationship between trust and reputation. As for single goods with repeat transactions, an iterative mathematical model of trust and reputation is established with a closed-loop feedback mechanism. Numerical experiments on repeated transactions recorded over a period of 24 months are performed. The experimental results show that the proposed method plays guiding roles for both theoretical research into trust and reputation and the practical design of reputation systems in BtoC e-commerce.

Characterization of ICT-based business models of social enterprises

In recent years new models for organizations working on overty alleviation have emerged. One of them, the social enterprise, has attracted the attention of both academics and practitioners all over the world. Even if defined in different ways depending on the context, social enterprise has an enormous potential to generate social benefits and to promote local agency and private initiative in poverty alleviation. In this sense, it is fitting to highlight the importance of identifying the main standards that permit the characterization of diverse social enterprises, in order to understand their main specificities and guarantee value generation for low-income populations. Another crucial factor is understanding innovation as a critical factor in promoting social enterprises. A powerful tool to enhance the impact and application of this model is Information and Communication Technologies. In the 21st century,these tools allow users to find new ways of collaboration, new sustainable business models and a cost-effective way of scaling-up initiatives. This paper, a product of the collaborative research between the Universidad Politécnica de Madrid and the Universidade Federal Fluminense, examines different business models for social enterprises and the role that ICT can play in scale and impact of these initiatives

Efficiency analysis of information technology and online social networks management : an integrated DEA-Model assessment

This paper analyses the relationship between productive efficiency and online-social-networks (OSN) in Spanish telecommunications firms. A data-envelopment-analysis (DEA) is used and several indicators of business ?social Media? activities are incorporated. A super-efficiency analysis and bootstrapping techniques are performed to increase the model?s robustness and accuracy. Then, a logistic regression model is applied to characterise factors and drivers of good performance in OSN. Results reveal the company?s ability to absorb and utilise OSNs as a key factor in improving the productive efficiency. This paper presents a model for assessing the strategic performance of the presence and activity in OSN.

Applying model-driven engineering to the development of Rich Internet Applications for Business Intelligence

Business Intelligence (BI) applications have been gradually ported to the Web in search of a global platform for the consumption and publication of data and services. On the Internet, apart from techniques for data/knowledge management, BI Web applications need interfaces with a high level of interoperability (similar to the traditional desktop interfaces) for the visualisation of data/knowledge. In some cases, this has been provided by Rich Internet Applications (RIA). The development of these BI RIAs is a process traditionally performed manually and, given the complexity of the final application, it is a process which might be prone to errors. The application of model-driven engineering techniques can reduce the cost of development and maintenance (in terms of time and resources) of these applications, as they demonstrated by other types of Web applications. In the light of these issues, the paper introduces the Sm4RIA-B methodology, i.e., a model-driven methodology for the development of RIA as BI Web applications. In order to overcome the limitations of RIA regarding knowledge management from the Web, this paper also presents a new RIA platform for BI, called RI@BI, which extends the functionalities of traditional RIAs by means of Semantic Web technologies and B2B techniques. Finally, we evaluate the whole approach on a case study—the development of a social network site for an enterprise project manager.

A Computational Model of the Belief System Under the Scope of Social Communication

This paper presents an approach to the belief system based on a computational framework in three levels: first, the logic level with the definition of binary local rules, second, the arithmetic level with the definition of recursive functions and finally the behavioural level with the definition of a recursive construction pattern. Social communication is achieved when different beliefs are expressed, modified, propagated and shared through social nets. This approach is useful to mimic the belief system because the defined functions provide different ways to process the same incoming information as well as a means to propagate it. Our model also provides a means to cross different beliefs so, any incoming information can be processed many times by the same or different functions as it occurs is social nets.

The Future of Model Germany: Challenges to the Corporatist System of Business Labor Relations. CES Germany & Europe Working Papers, No. 07.4, 12 December 1996

Germany's economic and social system faces immense economic, social, and political demands. These may be encapsulated in challenges like "new management concepts and labor policies," "deregulation of the infrastructure sector," "globalization," and "reunification." The paper analyzes these challenges and changes to the corporatist system of industrial relations--a cornerstone in .Model Germany's specific economic success and social consensus until now.

Az üzleti kapcsolatok menedzsmentjének gondolati modellje. És ez miért lehet fontos a vállalati vezetők számára? (The conceptual model of management of business relations – and why it may be important for the corporate executives?)

A szerzők cikkükben az üzleti marketinget és a gazdaságszociológiai megközelítést ötvözve vizsgálják az üzleti kapcsolatok irányításának néhány problémáját. Gondolati modelljük figyelembe veszi a kapcsolatra vonatkozó külső és belső szabályokat, a kapcsolatban érintettek percepcióit és cselekvéseit. Az üzleti kapcsolat menedzsmentje alatt elsősorban tervező, szervező és ellenőrző tevékenységeket értenek, amelyek attól függően alakulnak, hogy egy kapcsolat létrehozása, fenntartása vagy változtatása-e a cél. Reményeik szerint az általuk javasolt gondolati modell alkalmazása a társadalmi összetevők világosabb felismerésében segítheti az üzleti élet résztvevőit. Dolgozatuk célja az üzleti kapcsolatok menedzsmentjét megkönnyítő gondolati modell felállítása. A modell operacionalizálása és empirikus tesztelése meghaladja jelen írásuk kereteit és egy esetleges jövőbeni kutatás témája lehet. ____________ The purpose of this article is to create and demonstrate such a conceptual model, which might assist in the more efficient management of business relationships. The peculiarity of the way of thinking proposed by the authors is that it takes into account the complexity of business relationships and its social embeddedness. Thus they make an attempt to systematize the key components of business relationships, their processes, economic and social characteristics. The authors would like to approach this from the point of view of the management of the business relationship, trusting that the deeper understanding of the complexity of business relationships and the consistent consideration of this complexity may contribute to the more successful management of relationships.
