Abstract:
AbstractThough forged in the fires of the early nineteenth-century evangelical revivals, Primitive Baptists became the most significant opponents of the burgeoning antebellum evangelical movement. The Primitives were Calvinists who despised missionaries, Sunday schools, Bible tract societies, and the other accoutrements of evangelical Protestantism. This article contends that a feeling of uncertainty dominated Primitive Baptists' lives, catalyzed their movement's rise, and fueled their strident opposition to the theological and organizational changes shaping churches across the country. For Primitive Baptists, it was their questioning–especially their experience of persistent doubt–that set them apart from evangelicals. The uncertainty that colored Primitive Baptist selfhood motivated believers rather than paralyzed them. It propelled them toward a community of like-minded souls, and it stirred those souls to action as a more ardent brand of evangelical Protestantism crowded church pews. It is in the Primitives' uncertain selves–not in their theology or their socio-economic condition–that we find the most compelling explanation of their movement's unlikely rise.

Full text
Abstract:
This thesis examines the question of how primitive states form. The first part of the thesis defines a state. I then analyse Hobbes�s Theory of the Commonwealth by Acquisition (TCA), expounded in Leviathan. I conclude that this theory fails as an answer to the question of how primitive states form as it suffers from at least five major flaws. I go on to explain, modify and correct Hobbes�s TCA through techniques that have been used in modern critiques of Hobbes�s Theory of the Commonwealth by Institution. The result is the strongest possible answer that Hobbes can give to the question of how primitive states form. I conclude that his attempt fails as even if the technical aspects of his theory can be fixed, the overall problem of empirical falsification occurs. I then put forward my own theory, based on the modified Hobbesian theory. The major innovation is the replacement of individuals with groups in the Hobbesian State of Nature. This move answers the problem of empirical falsification, at least initially. The theory also helps to explain several of the more technical problems with Hobbes�s theory. The resulting theory is a Hobbesian theory of primitive state formation. The next step in the thesis is to match the Hobbesian theory of primitive state formation to the empirical evidence of primitive state formation, represented by anthropology. I analyse the anthropological literature and put forward that at least one recent research program in anthropology matches my Hobbesian theory of primitive state formation. I conclude that Hobbesian theory, based on the TCA can be successfully modernised into a plausible answer to the question of how primitive states formed.

Full text
Abstract:
This study was a comparative analysis of the highly structured legal systems of the state of Indiana and the United States of America and the unwritten legal systems of the Ashanti, Barotse, Buganda, and Nuer tribes of Africa. The purpose was to review the similarities and differences in the way in which those legal systems are structured, the way they function, and the scope of their impact on their respective societies.Complex societies have governmental entities which perform different functions in the legal system, but tribal societies tend to have people who perform multifunctional roles. The key is to observe the system to see what functions are being performed, and not to observe the system only to see if the same types of entities are performing the functions in simple societies as in complex societies.The “law is whatever is needed in a particular society. Dispute resolution must be accomplished, but the absence of a formal system does not mean the there is absence of law.

Full text
Abstract:
The general purpose of this thesis is to provide a gendered analysis of the ways in which States use their power to facilitate and promote accumulation, specifically primitive accumulation. I will seek to demonstrate in this study that women, classed and racialised, and especially those migrating within the neo-liberal global political economy are exploited not only through the classical alienation of their labour, but from the application of the additional extra-economic power of patriarchy and the tools that provides to states, and typically male owning classes. Women&rsquo
s position in patriarchal society and patriarchal capitalism may transform their experiences with capital and the state into a relationship of accumulation by dispossession rather than having their labour alienated and exploited under typical expanded reproduction. States use the constructions of women as subordinate under patriarchy, as well as others about migrant labour, or about the &lsquo
aberrant&rsquo
nature of sex work, to justify the use of women&rsquo
s bodies in the sex trade in a way that promotes the primitive accumulation, or accumulation by dispossession of surplus value from their labour and bodies. This study will use the Turkish Republic of northern Cyprus as an example to highlight the arguments made about the ability of a patriarchal state in collusion with capital, to use the extra controls afforded by patriarchy to primitively accumulate wealth from women, and to reproduce that ability on a continuous scale.

Abstract:
A civilização minóica da Creta da Idade do Bronze foi uma das poucas civilizações européias a organizar a sociedade através de um sistema palacial. Os estudos sobre a formação dos estados minóicos devem analisar em profundidade o sistema administrativo palacial e as mudanças no mesmo ao longo de seus seis séculos de funcionamento - neste trabalho pretende-se analisar a evolução da complexidade das unidades sócio-políticas minóicas através da análise de suas formas administrativas. A definição de categorias de sítios administrativos - pela análise funcional dos vestígios arquiteturais e dos achados arqueológicos dos mesmos - e o estudo dos padrões hierárquicos entre os diversos sítios, serão o cerne do trabalho. O uso de metodologias apropriadas para a análise de processos de mudança e formação de instituições político-administrativas, como a Teoria de Sistemas e os conceitos de peer polity interaction de Colin Renfrew, serão as ferramentas básicas deste projeto. Esse trabalho é um desdobramento de pesquisa desenvolvida em Mestrado realizado no MAE/USP sobre as interações entre os estados primitivos de Creta e as práticas de culto minóicas.
The Minoan Civilization of the Bronze Age Crete was one of the few european civilizations that organized its society through a palatial system. The studies about the development of the Minoan States must analyse thoroughness the administrative palatial system and the changes that have occured on it during its six centuries of functioning. In this thesis we intend to analyse the complexity evolution of the Minoan polities through the analysis of its administrative configurations. The definition of administrative sites - through the function analysis of the architectural vestiges and of its archaeological discoveries - and the study of the hierarchic patterns among the sites, will be the main point of this research. The use of usefull methodologies for the analysis of early state formation and culture change, like systems theory and the concepts of peer polity interaction, will be the basis tools of this project. This research follows research developed in the mastership done in MAE/USP about the interaction between the early states of Crete and the Minoan ritual practices.

AbstractWe develop a fully diagrammatic approach to finite-state automata, based on reinterpreting their usual state-transition graphical representation as a two-dimensional syntax of string diagrams. In this setting, we are able to provide a complete equational theory for language equivalence, with two notable features. First, the proposed axiomatisation is finite— a result which is provably impossible for the one-dimensional syntax of regular expressions. Second, the Kleene star is a derived concept, as it can be decomposed into more primitive algebraic blocks.

Abstract:
The options framework in reinforcement learning models the notion of a skill or a temporally extended sequence of actions. The discovery of a reusable set of skills has typically entailed building options, that navigate to bottleneck states. In this work, we instead adopt a complementary approach, where we attempt to discover options that navigate to landmark states. These states are prototypical representatives of well-connected regions and can hence access the associated region with relative ease. In this work, we propose Successor Options, which leverages Successor representations to build a model of the state space. The intra-option policies are learnt using a novel pseudo-reward and the model scales to high-dimensional spaces since it does not construct an explicit graph of the entire state space. Additionally, we also propose an Incremental Successor Options model that iterates between constructing Successor representations and building options, which is useful when robust Successor representations cannot be built solely from primitive actions. We demonstrate the efficacy of our approach on a collection of grid-worlds, and on the high-dimensional robotic control environment of Fetch.

Abstract:
The options framework provides a concrete way to implement and reason about temporally extended actions. Existing literature has demonstrated the value of planning with options empirically, but there is a lack of theoretical analysis formalizing when planning with options is more efficient than planning with primitive actions. We provide a general analysis of the convergence rate of a popular Approximate Value Iteration (AVI) algorithm called Fitted Value Iteration (FVI) with options. Our analysis reveals that longer duration options and a pessimistic estimate of the value function both lead to faster convergence. Furthermore, options can improve convergence even when they are suboptimal and sparsely distributed throughout the state space. Next we consider generating useful options for planning based on a subset of landmark states. This suggests a new algorithm, Landmark-based AVI (LAVI), that represents the value function only at landmark states. We analyze OFVI and LAVI using the proposed landmark-based options and compare the two algorithms. Our theoretical and experimental results demonstrate that options can play an important role in AVI by decreasing approximation error and inducing fast convergence.

Abstract:
Abstract This work concentrates on a common assembly primitive, threaded fastener insertion, in an effort to determine the nature of contact between a bolt and nut during thread mating. Contact state models were created to constrain the motion of the bolt at 1 and 2-point contacts. By analyzing the depth of intersection of the bolt into the nut as well as the vertical movement of the origin of the bolt reference frame, we determined that there are three types of contacts states present: unstable two-point, quasi-stable two-point, stable three point. Though the unstable case remains to be deciphered, the parametric equations derived in this work can be used without modification to create a full spectrum of maps at any point in the history of a threaded assembly problem. We investigated 81 potential orientations, each of which has its own set of contact points. From this exhaustive examination, we are capable of detailing a contact state history and, from this, have the potential to develop a constraint network.

Abstract:
The development of control software for mechatronic systems requires data and information from all design domains in order to create the required integrated functionality. This paper proposes a method that combines function modeling and multi-domain modeling primitives to generate control software. Provided a function model based on the Function-Behavior-State modeling paradigm and performance requirements, a knowledge-based engineering application instantiates a virtual product model and control software for a target platform. Object-oriented modeling techniques provide for the development of primitive libraries, which represent both hardware and software components, while integrated design rules ensure that components are correctly placed and connected. Requirements are translated to software specific parameters. A case study of a mobile robot shows that for specific applications both target and simulation control software code can be generated from the same input, and a generated virtual product model can serve as a simulation model in order to validate functionality.
