Institutions matter: essays on the determinants and consequences of socio-political institutions

ONLY AVAILABLE FOR CONSULTATION AT ASTON UNIVERSITY LIBRARY WITH PRIOR ARRANGEMENT This thesis seeks to contribute to the socio-political literature. It comprises of three individual chapters examining the determinants and consequences of different social-political institutional factors. Specifically, the first study combines game theoretical and empirical techniques to examine how bureaucrats favour other agents within their social group and the effects this will have on the level of corruption in the economy. To this end, I develop a simple model of allocation of time between economic activities and leisure (time spent building social network ties), to illustrate the underlying causal mechanism between social network and corruption. It shows that large social networks and low levels of economic activities provides the condition for high levels of corruption. However, the ability of the government to punish corruption through well-established laws and property rights enforcement acts as a deterrent to corruption. he second work also combines game theoretical and empirical techniques. It aims to clarify the relationship between the degree of competition and political influence of firms, paying particular attention to the level of government regulations that exist in the countries in which the firms operates. The interplay between economic and political institutions is vital to any analysis on understanding the workings of political influence. The third study is purely empirical. It examines the role of two types of business network, namely, political connections and business group affiliations on a firm’s performance. Evidence was provided on Chinese firms’ performance during the 2008 financial crisis.

X-Secure: protecting users from big bad wolves

In 2014 over 70% of people in Great Britain accessed the Internet every day. This resource is an optimal vector for malicious attackers to penetrate home computers and as such compromised pages have been increasing in both number and complexity. This paper presents X-Secure, a novel browser plug-in designed to present and raise the awareness of inexperienced users by analysing web-pages before malicious scripts are executed by the host computer. X-Secure was able to detect over 90% of the tested attacks and provides a danger level based on cumulative analysis of the source code, the URL, and the remote server, by using a set of heuristics, hence increasing the situational awareness of users browsing the internet.

¿Cómo compiten las firmas latinoamericanas en los mercados globalizados? La estrategia del grupo empresarial antioqueño para enfrentar la competencia internacional : El caso de Inversiones Nacional de Chocolates

En este artículo se presentan los resultados de la investigación que se desarrolló en Colombia, como parte del proyecto a nivel de América Latina, identificado como Can Latin American firms compete?, el cual fue auspiciado por Thunderbird: The Garvin School of International Management, con el fin de establecer cómo han logrado algunas firmas latinoamericanas extenderse exitosamente en los mercados internacionales e identificar la presencia de modelos y características comunes a estas empresas y sus pares en otras regiones del mundo. En Colombia se seleccionó al Grupo Empresarial Antioqueño y en particular su industria de alimentos, la cual conforma el conglomerado de empresas de Inversiones Nacional de Chocolates, como objetivo del estudio, teniendo en cuenta que este es posiblemente el grupo que reúne las mayores realizaciones en el proceso de internacionalización. En el trabajo se identifican las características sobresalientes que han permitido el desarrollo de competencias centrales (core competences), sobre las cuales se han establecido las estrategias para penetrar exitosamente en diferentes mercados internacionales, el aprendizaje de las diferentes culturas propias de esos mercados, y los procesos que se desarrollaron para enfrentar los riesgos, darles valor a los productos y enfrentar la creciente competencia de otras firmas multinacionales.

Big data, smart homes and ambient assisted living

Objectives: To discuss how current research in the area of smart homes and ambient assisted living will be influenced by the use of big data. Methods: A scoping review of literature published in scientific journals and conference proceedings was performed, focusing on smart homes, ambient assisted living and big data over the years 2011-2014. Results: The health and social care market has lagged behind other markets when it comes to the introduction of innovative IT solutions and the market faces a number of challenges as the use of big data will increase. First, there is a need for a sustainable and trustful information chain where the needed information can be transferred from all producers to all consumers in a structured way. Second, there is a need for big data strategies and policies to manage the new situation where information is handled and transferred independently of the place of the expertise. Finally, there is a possibility to develop new and innovative business models for a market that supports cloud computing, social media, crowdsourcing etc. Conclusions: The interdisciplinary area of big data, smart homes and ambient assisted living is no longer only of interest for IT developers, it is also of interest for decision makers as customers make more informed choices among today's services. In the future it will be of importance to make information usable for managers and improve decision making, tailor smart home services based on big data, develop new business models, increase competition and identify policies to ensure privacy, security and liability.

Knowledge-based management systems for the police force

Knowledge-Based Management Systems enable new ways to process and analyse knowledge to gain better insights to solve a problem and aid in decision making. In the police force such systems provide a solution for enhancing operations and improving client administration in terms of knowledge management. The main objectives of every police officer is to ensure the security of life and property, promote lawfulness, and avert and distinguish wrongdoing. The administration of knowledge and information is an essential part of policing, and the police ought to be proactive in directing both explicit and implicit knowledge, whilst adding to their abilities in knowledge sharing. In this paper the potential for a knowledge based system for the Mauritius police was analysed, and recommendations were also made, based on requirements captured from interviews with several long standing officers, and surveying of previous works in the area.

Análisis de tecnologías eco eficientes para la disposición final de residuos sólidos en las empresas Coraseo S.A y Seacor S.A

Los residuos sólidos como consecuencia directa de las actividades humanas, han representado un reto desde sus inicios, de ahí se empezaron a desarrollar técnicas y prácticas para garantizar una adecuada gestión de los residuos, nuestros primeros ancestros encontraron en los botaderos a cielo abierto la solución más fácil para disponer los desechos de animales y residuos de comida en sitios cercanos a sus viviendas, por ejemplo, los griegos poseen registros de la inauguración del primer relleno municipal en la ciudad de Atenas hace más de 2000 años. La evolución de las culturas, la revolución industrial y el crecimiento poblacional acelerado han modificado no solo la composición sino también la cantidad de los residuos sólidos producidos, haciendo cada día más difícil su adecuada gestión debido a su alto grado de toxicidad, la ausencia de materiales biodegradables y su volumen, traduciendo esto en un gran impacto. El panorama no es muy alentador y los pronósticos emitidos por el Banco Mundial prevén que para el año 2025 los niveles mundiales de residuos sólidos urbanos alcanzaran 2,2 millones de toneladas por año. Basada en el interés por la adecuada gestión de los residuos y la disminución del impacto ambiental de las empresas Coraseo S.A y Seacor S.A, la presente investigación busca seleccionar la metodología y/o tecnología más apropiada teniendo en cuenta las condiciones económicas, logísticas y de infraestructura de la empresa y la comunidad involucrada. En primera instancia se estudió en profundidad el panorama empresarial y posteriormente se seleccionó un grupo de cuatro propuestas para la transformación y aprovechamiento de los residuos sólidos que fueron evaluadas a nivel económico, normativo, medio ambiental. Los datos analizados sugieren entre otras cosas, un robustecimiento del marco legal ambiental colombiano y mundial, una mayor colaboración económica de los organismos internacionales y las entidades bancarias y finalmente una reducción en los costos de las tecnologías disponibles para el aprovechamiento de los residuos sólidos, haría posible el sueño de las sociedades de gestionar efectivamente los residuos sólidos generando el menor impacto ambiental posible y en el caso del grupo empresarial Cordobés lograr innovar y emprender con un proyecto eco eficiente como el que se evaluó.

Las dos caras de la organización del mundial FIFA Brasil 2014: Entre la proyección internacional y las denuncias sociales

El orgullo brasileño estalló en el año 2007, cuando Brasil fue elegido sede del mundial FIFA 2014. Esto se debe a que Brasil en ese momento gozaba de un creciente prestigio internacional por cuenta de su condición de Potencia Emergente, miembro de los BRICS, aspirante a un puesto permanente en el Consejo de Seguridad y contar con la selección de fútbol más exitosa de la historia. No obstante, en su afán por incrementar su visibilidad y proyección internacional acudió al ejercicio del Poder Blando, a través de la Diplomacia Cultural, concretamente se decidió por la Organización de Mega Eventos deportivos, al tiempo que debía enfrentar varios problemas en el ámbito interno (desigualdad, corrupción, pobreza). Así, esta estrategia de aplicación del Poder Blando resultó de cierta manera contraproducente, debido a que la política exterior y su éxito no suele estar disociada de la realidad interna.

A literature review to Examine the Validity and Reliability of group poster presentations as an assessment method of a module in an undergraduate nursing degree programme

The introduction of a poster presentation as a formative assessment method over a multiple choice examination after the first phase of a three phase “health and well-being” module in an undergraduate nursing degree programme was greeted with a storm of criticism from fellow lecturers stating that poster presentations are not valid or reliable and totally irrelevant to the assessment of learning in the module. This paper seeks to investigate these criticisms by investigating the literature regarding producing nurses fit for practice, nurse curriculum development and wider nurse education, the purpose of assessment, validity and reliability to critically evaluate the poster presentation as a legitimate assessment method for these aims.

Collaborative business process modeling using 3D virtual environments

Process modeling is a complex organizational task that requires many iterations and communication between the business analysts and the domain specialists involved in the process modeling. The challenge of process modeling is exacerbated, when the process of modeling has to be performed in a cross-organizational, distributed environment. Some systems have been developed to support collaborative process modeling, all of which use traditional 2D interfaces. We present an environment for collaborative process modeling, using 3D virtual environment technology. We make use of avatar instantiations of user ego centres, to allow for the spatial embodiment of the user with reference to the process model. We describe an innovative prototype collaborative process modeling approach, implemented as a modeling environment in Second Life. This approach leverages the use of virtual environments to provide user context for editing and collaborative exercises. We present a positive preliminary report on a case study, in which a test group modelled a business process using the system in Second Life.

Using virtual worlds for collaborative business process modeling

Purpose Process modeling is a complex organizational task that requires many iterations and communication between the business analysts and the domain specialists. The challenge of process modeling is exacerbated, when the process of modeling has to be performed in a cross-organizational, distributed environment. In this paper we suggest a 3D environment for collaborative process modeling, using Virtual World technology. Design/methodology/approach We suggest a new collaborative process modeling approach based on Virtual World technology. We describe the design of an innovative prototype collaborative process modeling approach, implemented as a 3D BPMN modeling environment in Second Life. We use a case study to evaluate the suggested approach. Findings Based on our case study application, we show that our approach increases user empowerment and adds significantly to the collaboration and consensual development of process models even when the relevant stakeholders are geographically dispersed. Research limitations implications – We present design work and a case study. More research is needed to more thoroughly evaluate the presented approach in a variety of real-life process modeling settings. Practical implications Our research outcomes as design artifacts are directly available and applicable by business process management professionals and can be used by business, system and process analysts in real-world practice. Originality/value Our research is the first reported attempt to develop a process modeling approach on the basis of virtual world technology. We describe a novel and innovative 3D BPMN modeling environment in Second Life.
