The problem is limited to an analysis of the first one hundred divorce suits involving children filed in Dallas County, Texas, during the months of May and June, 1948. The general factors considered are: (a) family background; (b) age; (c) educational background; (d) economic status; (e) previous marital relations; and (f) the number of children.

This thesis aimed to develop a measure to investigate the perceived motivational climate in individual sports. In particular, it aimed to address some of the knowledge gaps in the current literature examining motivational climates: by developing a measure whose intended population participate in individual sports; that incorporates the perceived motivational climate created by multiple significant others; and that incorporates the 'impact' or salience of each of these perceptions of the motivational climate. In order to achieve this, the thesis is comprised of four studies.

O objetivo deste trabalho é determinar quais são os dilemas, quais são os dilemas em bioética, quais são os assuntos comuns a todos os dilemas e classificar dilemas em bioética dividindo-os em categorias para diminuir a incerteza em torno destas discussões políticas. Eu pretendo construir um sistema que poderia ajudar-nos especialistas em ética, eticistas, reconhecer o que questões que estamos lidando e que, provavelmente, seria um primeiro passo para a resolução de dilemas em bioética. / This is a dissertation about bioethical dilemmas. The aim of this work is to determine what are dilemmas, what are dilemmas in bioethics, what are the subjects common to all dilemmas and classify dilemmas in bioethics dividing them into categories to diminish the fuzziness around these polemical discussions. I plan to build a system that could help us, ethicists, recognize what issues we are dealing with and that would probably would be a first step towards the resolution of dilemmas in bioethics. The scope of the work will be: this introduction, a chapter about dilemmas divided into simplified dilemmas, amplified dilemmas and moral mathematics and bioethical dilemmas: why solve them, a chapter about problems involving all dilemmas: the matter of time and well-being and suffering, a chapter on a proposal on bioethical dilemmas: identity dilemmas, self-consciousness dilemmas, future suffering dilemmas and freedom dilemmas and the conclusion.

Mobile Advertising is considered to be an unlimited industry in business opportunities, and the relative chain in Taiwan has become mature. When the technology has improved a lot, we should come up with a business model to maximize the potential of mobile advertising. This article focus on the factor of mobile acceptance, and analysis the relationship between acceptance and advertising effect. Also, we observe the effects of involvement and the structure of mobile advertising. We obtained some conclusions as following. 1. The factors that affect mobile advertising are utility, context, the sacrifice of controlling, the cost of receiving and the degree of trust. Especially we view context and the degree of trust are the most important factors of all. 2. The acceptance of mobile advertising will affect the attitude towards advertising, the attitude towards brand and the intention of purchasing.3. The adjust function of involvement between acceptance and advertising effects is not significant. 4. The adjust function of the structure of mobile advertising between acceptance and advertising effects is also not significant.

Terrorism threatens both international peace and security and is a national concern. It is believed that terrorist organizations rely heavily on a few key leaders and that destroying such an organization's leadership is essential to reducing its influence. Martonosi et al. (2011) argues that increasing the amount of communication through a key leader increases the likelihood of detection. If we model a covert organization as a social network where edges represent communication between members, we want to determine the subset of members to remove that maximizes the amount of communication through the key leader. A mixed-integer linear program representing this problem is presented as well as a decomposition for this optimization problem. As these approaches prove impractical for larger graphs, often running out of memory, the last section focuses on structural characteristics of vertices and subsets that increase communication. Future work should develop these structural properties as well as heuristics for solving this problem.

In today’s inter-connected world, threats from anywhere in the world can have serious global repercussions. In particular, two types of threats have a global impact: 1) cyber crime and 2) cyber and biological weapons. If a country’s environment is conducive to cyber criminal activities, cyber criminals will use that country as a basis to attack end-users around the world. Cyber weapons and biological weapons can now allow a small actor to inflict major damage on a major military power. If cyber and biological weapons are used in combination, the damage can be amplified significantly. Given that the cyber and biological threat is global, it is important to identify countries that pose the greatest threat and design action plans to reduce the threat from these countries. However, prior work on cyber crime lacks empirical substantiation for reasons why some countries’ environments are conducive to cyber crime. Prior work on cyber and biological weapon capabilities mainly consists of case studies which only focus on select countries and thus are not generalizeable. To sum up, assessing the global cyber and biological threat currently lacks a systematic empirical approach. In this thesis, I take an empirical and systematic approach towards assessing the global cyber and biological threat. The first part of the thesis focuses on cyber crime. I examine international variation in cyber crime infrastructure hosting and cyber crime exposure. I also empirically test hypotheses about factors behind such variation. In that work, I use Symantec’s telemetry data, collected from 10 million Symantec customer computers worldwide and accessed through the Symantec’s Worldwide Intelligence Network Environment (WINE). I find that addressing corruption in Eastern Europe or computer piracy in Sub-Saharan Africa has the potential to reduce the global cyber crime. The second part of the thesis focuses on cyber and biological weapon capabilities. I develop two computational methodologies: one to assess countries’ biological capabilities and one to assess countries’ cyber capabilities. The methodologies examine all countries in the world and can be used by non-experts that only have access to publicly available data. I validate the biological weapon assessment methodology by comparing the methodology’s assessment to historical data. This work has the potential to proactively reduce the global cyber and biological weapon threat.
