The Arab monarchies of the Gulf have been undergoing striking socio-economic changes caused by the ending of the rent-based welfare state model on which they had largely relied since the 1950s. In this perspective, this paper aims at examining the comparative role of local business communities in affecting the orientations and the outcomes of the policies implemented during the period of high oil prices in the 2000s. This paper pays a special attention to the impact of the Arab Spring on the state-business relations in two of the smaller Gulf monarchies (Bahrain and Oman).

Elections play a crucial role in political stability in post-democratization, and electoral administrations are the key to the electoral process. However, not all newly democratized countries have established reliable electoral administration. New democracies in Southeast Asia, such as the Philippines, Indonesia and Thailand, have independent election commissions which have different characteristics, especially in terms of neutrality. Based on three cases, this paper claims that the stakes of politics are the major determinant of the variations in neutrality. The high stakes of politics in Thailand brought about the partisan election commission, while the low stakes in Indonesia made the electoral system relatively neutral. Like Thailand, the high stakes of politics in the Philippines also cause political intervention in the electoral administration.

Evidence suggests that incumbent parties find it harder to be re-elected in emerging than in advanced democracies because of more serious economic problems in the former. Yet the pro-Islamic Justice and Development Party (AKP) has ruled Turkey since 2002. Does economic performance sufficiently account for the electoral strength of the AKP government? Reliance on economic performance alone to gain public support makes a government vulnerable to economic fluctuations. This study includes time-series regressions for the period 1950-2011 in Turkey and demonstrates that even among Turkey's long-lasting governments, the AKP has particular electoral strength that cannot be adequately explained by economic performance.

In this study, we examine the voting behavior in Indonesian parliamentary elections from 1999 to 2014. After summarizing the changes in Indonesian parties' share of the vote from a historical standpoint, we investigate the voting behavior with simple regression models to analyze the effect of regional characteristics on Islamic/secular parties' vote share, using aggregated panel data at the district level. Then, we also test the hypothesis of retrospective economic voting. The results show that districts which formerly stood strongly behind Islamic parties continued to select those parties, or gave preference to abstention over the parties in some elections. From the point of view of retrospective economic voting, we found that districts which experienced higher per capita economic growth gave more support to the ruling parties, although our results remain tentative because information on 2014 is not yet available.

The problem of social diffusion has animated sociological thinking on topics ranging from the spread of an idea, an innovation or a disease, to the foundations of collective behavior and political polarization. While network diffusion has been a productive metaphor, the reality of diffusion processes is often muddier. Ideas and innovations diffuse differently from diseases, but, with a few exceptions, the diffusion of ideas and innovations has been modeled under the same assumptions as the diffusion of disease. In this dissertation, I develop two new diffusion models for "socially meaningful" contagions that address two of the most significant problems with current diffusion models: (1) that contagions can only spread along observed ties, and (2) that contagions do not change as they spread between people. I augment insights from these statistical and simulation models with an analysis of an empirical case of diffusion - the use of enterprise collaboration software in a large technology company. I focus the empirical study on when people abandon innovations, a crucial, and understudied aspect of the diffusion of innovations. Using timestamped posts, I analyze when people abandon software to a high degree of detail.
To address the first problem, I suggest a latent space diffusion model. Rather than treating ties as stable conduits for information, the latent space diffusion model treats ties as random draws from an underlying social space, and simulates diffusion over the social space. Theoretically, the social space model integrates both actor ties and attributes simultaneously in a single social plane, while incorporating schemas into diffusion processes gives an explicit form to the reciprocal influences that cognition and social environment have on each other. Practically, the latent space diffusion model produces statistically consistent diffusion estimates where using the network alone does not, and the diffusion with schemas model shows that introducing some cognitive processing into diffusion processes changes the rate and ultimate distribution of the spreading information. To address the second problem, I suggest a diffusion model with schemas. Rather than treating information as though it is spread without changes, the schema diffusion model allows people to modify information they receive to fit an underlying mental model of the information before they pass the information to others. Combining the latent space models with a schema notion for actors improves our models for social diffusion both theoretically and practically.
The empirical case study focuses on how the changing value of an innovation, introduced by the innovations' network externalities, influences when people abandon the innovation. In it, I find that people are least likely to abandon an innovation when other people in their neighborhood currently use the software as well. The effect is particularly pronounced for supervisors' current use and number of supervisory team members who currently use the software. This case study not only points to an important process in the diffusion of innovation, but also suggests a new approach -- computerized collaboration systems -- to collecting and analyzing data on organizational processes.

Invasion waves of cells play an important role in development, disease and repair. Standard discrete models of such processes typically involve simulating cell motility, cell proliferation and cell-to-cell crowding effects in a lattice-based framework. The continuum-limit description is often given by a reaction–diffusion equation that is related to the Fisher–Kolmogorov equation. One of the limitations of a standard lattice-based approach is that real cells move and proliferate in continuous space and are not restricted to a predefined lattice structure. We present a lattice-free model of cell motility and proliferation, with cell-to-cell crowding effects, and we use the model to replicate invasion wave-type behaviour. The continuum-limit description of the discrete model is a reaction–diffusion equation with a proliferation term that is different from lattice-based models. Comparing lattice based and lattice-free simulations indicates that both models lead to invasion fronts that are similar at the leading edge, where the cell density is low. Conversely, the two models make different predictions in the high density region of the domain, well behind the leading edge. We analyse the continuum-limit description of the lattice based and lattice-free models to show that both give rise to invasion wave type solutions that move with the same speed but have very different shapes. We explore the significance of these differences by calibrating the parameters in the standard Fisher–Kolmogorov equation using data from the lattice-free model. We conclude that estimating parameters using this kind of standard procedure can produce misleading results.

A computational model for the interrelated phenomena in the process of vacuum arc remelting is analyzed and adjusted of optimal accuracy and computation time. The decision steps in this case study are offered as an example how the coupling in models of similar processes can be addressed. Results show dominance of the electromagnetic forces over buoyancy and inertia for the investigated process conditions.

O presente trabalho tem por objetivo analisar, pela ótica da teoria do rent seeking, a evolução da legislação e da jurisprudência administrativa e judicial acerca do regime da tributação dos lucros, ganhos de capital e rendimentos auferidos por sociedades controladas e coligadas no exterior. Observar-se-á a hipótese da legislação e das suas diversas interpretações refletirem interesses predominantemente de apropriação de renda, tanto por parte da Administração Pública quanto dos agentes privados. Nesse sentido, após uma exposição da teoria do rent seeking e da sua relação com a teoria do patrimonialismo no Brasil, ela será aplicada no tema tributário proposto. Para tanto, verificar-se-á a evolução da legislação até o último diploma normativo relevante sobre o tema: a Medida Provisória nº 2.158-35/01. Neste momento, serão identificadas as principais controvérsias e os possíveis interesses nas diversas interpretações dadas às regras em questão, associando-os com os diversos problemas de rent seeking observáveis. A seguir, verificar-se-á, nas decisões do Superior Tribunal de Justiça (STJ), do Supremo Tribunal Federal (STF), e do Conselho Administrativo de Recursos Fiscais (CARF) qual a evolução do entendimento dos tribunais a respeito das referidas interpretações, verificando se algum consenso foi atingido e quais interesses estariam atingidos pelo rumo tomado pela jurisprudência sobre o tema. Neste contexto, a análise da evolução legislativa e jurisprudencial abordará os seguintes pontos controversos: (1) caracterização das regras brasileiras como CFC rules (característica antielisiva); (2) tributação de distribuição ficta ou de lucro da própria controladora ou coligada no Brasil; (3) constitucionalidade do artigo 43, parágrafo 2º, do Código Tributário Nacional, bem como do artigo 74 da Medida Provisória nº 2.158-35/01; e (4) a compatibilização com os Tratados contra a Dupla Tributação. Por fim, far-se-á uma conclusão, a partir dos resultados verificados, a respeito de como a evolução das regras tributárias em questão pode representar uma apropriação de renda sem benefícios públicos que pode favorecer indevidamente tanto o setor público como o privado.

In 2002, the United Nations Office on Drugs and Crime (UNODC) issued a report entitled Results of a pilot survey of forty selected organized criminal groups in sixteen countries which established five models of organised crime. This paper reviews these and other common organised crime models and drug trafficking models, and applies them to cases of South East Asian drug trafficking in the Australian state of Queensland. The study tests the following hypotheses: (1) South-East Asian drug trafficking groups in Queensland will operate within a criminal network or core group; (2) Wholesale drug distributors in Queensland will not fit consistently under any particular UN organised crime model; and (3) Street dealers will have no organisational structure. The study concluded that drug trafficking or importation closely resembles a criminal network or core group structure. Wholesale dealers did not fit consistently into any UN organised crime model. Street dealers had no organisational structure as an organisational structure is typically found in mid- to high-level drug trafficking.

In his 2007 PESA keynote address, Paul Smeyers discussed the increasing regulation of child-rearing through government intervention and the generation of “experts,” citing particular examples from Europe where cases of childhood obesity and parental neglect have stirred public opinion and political debate. In his paper (this issue), Smeyers touches on a number of tensions before concluding that child rearing qualifies as a practice in which liberal governments should be reluctant to intervene. In response, I draw on recent experiences in Australia and argue that certain tragic events of late are the result of an ethical, moral and social vacuum in which these tensions coalesce. While I agree with Smeyers that governments should be reluctant to “intervene” in the private domain of the family, I argue that there is a difference between intervention and support. In concluding, I maintain that if certain Western liberal democracies did a more comprehensive job of supporting children and their families through active social investment in primary school education, then both families and schools would be better equipped to deal with the challenges they now face.

This thesis makes several contributions towards improved methods for encoding structure in computational models of word meaning. New methods are proposed and evaluated which address the requirement of being able to easily encode linguistic structural features within a computational representation while retaining the ability to scale to large volumes of textual data. Various methods are implemented and evaluated on a range of evaluation tasks to demonstrate the effectiveness of the proposed methods.
