Interdependence in Southern Africa: an examination of the relations between Zimbabwe and South Africa

Most research on southern Africa focuses on the total dependency of the region's states--Angola, Botswana, Lesotho, Malawi, Mozambique, Swaziland, zambia and Zimbabwe--upon the dominant power, South Africa. This thesis examines the relationship between South Africa and Zimbabwe and argues that these two states are more interdependent than dependency scholars would acknowledge. Although a study of the historical period reveals that dependency theory, as defined by Raul Prebisch, Andre Gunder Frank and A. Valenzuela, is helpful for understanding the development of relations between the two states, it is unable to account for many of the characteristics of the relationship which are found in the contemporary context, especially since 1980. An examination of various economic areas of interaction, including investment, trade and transportation, as well as the political realm, indicates that each state exhibits a degree of dependence upon the other. Thus, it is possible to characterize the relationship as one of "mutual dependence," or interdependence as defined by Robert Keohane and Joseph S. Nye. Interdependence is further examined through the concepts of sensitivity and vulnerability. Sensitivity signifies the ability of a state to respond effectively to policy changes made by another state wi thin a given area of interaction without incurring large costs, while vulnerability denotes that an actor is unable to respond, or only at great cost. By applying these concepts to the relationship between Zimbabwe and South Africa, it is determined that although South Africa tends to be sensitive while Zimbabwe is generally vulnerable, the degrees to which these two states are sensi ti ve and vulnerable varies over time and issue area. As the changes wi thin South Africa start to affect relations wi th the rest of southern Africa, it wi 11 be necessary to understand the interaction between the states from an interdependency perspective if cooperation within the region wi 11 be successful. By appl ying an interdependence framework, this study aims at contributing to the understanding of relations among the countries of southern Africa in general, and between South Africa and Zimbabwe in particular.

Polytypism and Silicon carbide : a solid state nuclear magnetic resonance study

A survey of predominantly industrial silicon carbide has been carried out using Magic Angle Spinning nuclear magnetic resonance (MAS nmr); a solid state technique. Three silicon carbide polytypes were studied; 3C, 6H, and 15R. The 13C and 29 Si MAS nmr spectra of the bulk SiC sample was identified on the basis of silicon (carbon) site type in the d iff ere n t pol Y t Y pes • Out to 5.00 A fro mac en t r a lsi 1 i con (0 r carbon) atom four types of sites were characterized using symmetry based calculations. This method of polytype analysis was also considered, in the prelminary stages, for applications with other polytypic material; CdBr 2 , CdI 2 , and PbI 2 " In an attempt to understand the minor components of silicon carbide, such as its surface, some samples were hydrofluoric acid washed and heated to extreme temperatures. Basically, an HF removable species which absorbs at -110 ppm (Si0 2 ) in the 29 Si MAS nmr spectrum is found in silicon carbide after heating. Other unidentified peaks observed at short recycle delays in some 29 Si MAS nmr spectra are considered to be impurities that may be within the lattice. These components comprise less than 5% of the observable silicon. A Tl study was carried out for 29 Si nuclei in a 3C ii polytype sample, using the Driven Equilibrium Single-Pulse Observation of T1 (DESPOT) technique. It appears as though there are a number of nuclei that have the same chemical shift but different T1 relaxation times. The T1 values range from 30 seconds to 11 minutes. Caution has to be kept when interpreting these results because this is the first time that DESPOT has been used for solid samples and it is not likely in full working order. MAS nmr indicates that the 13C and 29 Si ~sotropic chemical shifts of silicon carbide appear to have a reciprocal type of relationship_ Single crystal nmr analysis of a 6H sample is accordance with this finding when only the resultant isotropic shift is considered. However, single crystal nmr also shows that the actual response of the silicon and carbon nuclear environment to the applied magnetic field at various angles is not at all reciprocal. Such results show that much more single crystal nmr work is required to determine the actual behavior of the local magnetic environment of the SiC nuclei.

Everything that rises must converge: a neo-Marxist analysis of Canadian business-government relations

The following thesis presents an analysis of business-government relations within a neo-Marxist framework. Specifically, the discussion encompasses how the business interest group. the Business Council on National Issues, maintains consensus and unity amongst its monopoly capital members. Furthermore. the study elaborates on the process through which the group's interests are acknowledged and legitimized by the state under the "public interest" f8fue. Most of the literature pertaining to business-government relations within the context of interactions between business interest groups and the state, and such specific branches of the state as the government and/or the civil service. emphasize a liberal-pluralist perspective. Essentially, these writings serve to reflect and legitimate the current slatus quo. Marxist discourses on the subject, while attempting to transcend the liberal-pluralist framework. nevertheless suffer from either economic determinism .. ie., stressing the state's accumulation function but not its legitimation function or historical specificity. A cogent and comprehensive neo-Marxist analysis of business-government relations must discuss both the accumulation and legitimation functions of the state. The process by which the concerns of a particular business interest group become part of the state's policy agenda and subsequently are formulated and implemented into policies which legitimate its dominance is also studied. This inquiry is significant given the liberal-pluralist assumptions of a neutral state and that all interest groups compete "on a level playing field". The author's neo-Marxist paradigm rejects both of these assumptions. Building on concepts from nea-Marxist instrumentalism. structuralism. state monopoly capitalism, and forms and functions of the state perspectives. the author proposes that policies which legitimize the interests of the monopoly capital fraction cannot. be discerned only from the state's activities. per StJ. Clearly, if the liberal-pluralist 3 contention of multiple and conflicting interest groups, including those within the capitalist class, is taken at face value, M interest group such as the Business Council on National Issues (BCND, must somehow maintain. internal consensus Md unity amongst its members. Internal consensus amongst its members ensures that the state can better acknowledge and articulate its concerns into policies that maintain hegemonic dominance of the monopoly capital fraction under the "public interest" fllf.JJdq. The author contends that the BCNI focuses most of its interactions on the upper echelons of the civil service since it is this branch of the state which is most responsible for policy formulation and implementation. The author's paradigm is applied within the context of extensively analyzing newspaper coverage. BCN! publications, and other published sources, as well as a personal interview with an executive administrative member of the BeNI. The discussion focuses on how agreement and unity amongst the various interests of the monopoly capital fraction are maintained through the business organization, its policy scope, and finally its interactions with the state. The analysis suggests that while the civil service is an important player in expressing the interests of the BCNI's membership through policies which ostensibly also reflect the "public interest", it is not the only strategic target for the BCNI's interactions with the state. The author's research also highlights the importance of government officials at the Cabinet level and Cabinet Committees. Senior elected officials from the Federal government are also significant in avoiding intergovernmental or interprovincial conflict in implementing policies that legitimize hegemonic dominance of the monopoly capital fraction over other fractions and classes.

A Foucaultian analysis of power relations in child protection case work with youth and families

This thesis takes some steps in examining the child protection system from a position that is rarely discussed. Specifically, I explore how Foucault's concept of disciplinary power can be used to demonstrate how power operates within the client/worker relationship. This relationship is shown to be quite complex with power flowing bidirectionally, rather than hierarchically. Instead of viewing power imbalances as a function of state control, I show how the client/worker relationship is constituted by the worker, the client, the organization and the social body. A postmodern auto ethnography is used to document my journey as I expose the disciplinary practices and instruments that I was subject to and used with my clients. 2 Given that the child protection system is constantly shifting and changing in order to improve its ability to safeguard children a greater emphasis is required to examine how workers operate within this complex, overwhelming and multi-dimensional world. This thesis has shown that by engaging in a reflexive examination of my position of power different approaches to making intervention beneficial to all involved become available. This is important if child protection work aims to work with clients rather than on clients.

RelMDD-A Library for Manipulating Relations Based on MDDs

Relation algebras is one of the state-of-the-art means used by mathematicians and computer scientists for solving very complex problems. As a result, a computer algebra system for relation algebras called RelView has been developed at Kiel University. RelView works within the standard model of relation algebras. On the other hand, relation algebras do have other models which may have different properties. For example, in the standard model we always have L;L=L (the composition of two (heterogeneous) universal relations yields a universal relation). This is not true in some non-standard models. Therefore, any example in RelView will always satisfy this property even though it is not true in general. On the other hand, it has been shown that every relation algebra with relational sums and subobjects can be seen as matrix algebra similar to the correspondence of binary relations between sets and Boolean matrices. The aim of my research is to develop a new system that works with both standard and non-standard models for arbitrary relations using multiple-valued decision diagrams (MDDs). This system will implement relations as matrix algebras. The proposed structure is a library written in C which can be imported by other languages such as Java or Haskell.

Substance P, récepteurs NK1 et neurones à sérotonine : relations anatomiques et fonctionnelles dans le noyau raphe dorsalis

Nous avons étudié les relations anatomiques entre les systèmes de neurotransmission à substance P (SP) et à sérotonine (5-hydroxytryptamine, 5-HT) dans le noyau du raphé dorsal (NRD) du rongeur, afin de mieux comprendre les interactions entre ces systèmes durant la régulation de l’humeur. Le NRD reçoit une innervation SP provenant de l’habenula, et le blocage pharmacologique des récepteurs neurokinine-1 (rNK1) de la SP aurait des effets antidépresseurs. Chez le rongeur, le traitement par les antagonistes des rNK1 s’accompagne d’une désensibilisation des autorécepteurs 5-HT1A de la 5-HT et d’une hausse de l’activité des neurones 5-HT dans le NRD, suggérant des interactions locales entre ces deux systèmes. Dans un premier temps, nous avons démontré par doubles marquages immunocytochimiques en microscopies optique, confocale et électronique, la présence du rNK1 dans une sous-population de neurones 5-HT du NRD caudal. Lors de l’analyse en microscopie électronique, nous avons pu constater que les rNK1 étaient principalement cytoplasmiques dans les neurones 5-HT et membranaires sur les neurones non 5-HT du noyau. Grâce à d’autres doubles marquages, nous avons aussi pu identifier les neurones non-5-HT porteurs de rNK1 comme étant GABAergiques. Nous avons ensuite combiné l’immunomarquage de la SP avec celui du rNK1, dans le but d’examiner les relations entre les terminaisons (varicosités *) axonales SP et les neurones 5-HT (pourvus de rNK1 cytoplasmiques du NRD caudal. En simple marquage de la SP, nous avons pu estimer à 41% la fréquence avec laquelle les terminaisons SP font synapse. Dans le matériel doublement marqué pour la SP et son récepteur, les terminaisons SP ont été fréquemment retrouvées en contact direct ou à proximité des dendrites munies de rNK1 cytoplasmiques, mais toujours éloignées des dendrites à rNK1 membranaires. Pour tester l’hypothèse d’une internalisation soutenue des rNK1 par la SP dans les neurones 5-HT, nous avons ensuite examiné la localisation subcellulaire du récepteur chez le rat traité avec un antagoniste du rNK1, le RP67580. La densité du marquage des rNK1 a été mesurée dans le cytoplasme et sur la membrane des deux types de dendrites (5-HT: rNK1 cytoplasmiques; non 5-HT: rNK1 membranaires). Une heure après une injection unique de l’antagoniste, la distribution du rNK1 est apparue inchangée dans les deux types de neurones (5-HT et non 5-HT). Par contre, après un traitement quotidien de 7 ou 21 jours avec l’antagoniste, nous avons mesuré une augmentation significative des densités cytoplasmique et membranaire du rNK1 dans les neurones 5-HT, sans aucun changement dans les neurones non 5-HT. Ces traitements ont aussi augmenté l’expression du gène rNK1 dans le NRD. Enfin, nous avons mesuré une hausse de la densité membranaire du rNK1 dans les neurones 5-HT, sans hausse de densité cytoplasmique, par suite d’une lésion bilatérale de l’habenula. Ces résultats confortent l’hypothèse d’une activation et d’une internalisation soutenues des rNK1 par la SP dans les neurones 5-HT du NRD caudal. Ils suggèrent aussi que le trafic des rNK1 dans les neurones 5-HT du NRD représente un mécanisme cellulaire en contrôle de l’activation du système 5-HT par les afférences SP en provenance de l’habenula.

Vers un rééchelonnement de la citoyenneté en France et au Québec : les politiques de gestion de la diversité ethnique à Marseille et Montréal

La thèse analyse les recompositions de la citoyenneté dans un contexte de rééchelonnement de l’État en France et au Québec. L’argument est que, dans un tel contexte, la citoyenneté nationale se rééchelonne. Le cadre théorique consiste en une relecture institutionnelle du concept de rééchelonnement de l’État développé par N. Brenner ainsi que certains apports des travaux de J. Jenson et S. Phillips sur les régimes de citoyenneté. La thèse compare les évolutions de politiques de gestion de la diversité ethnique - centrales dans l’analyse de la citoyenneté - à Marseille et Montréal au travers des reconfigurations des rapports entre acteurs institutionnels prenant place à l’échelle locale. Nous montrons que l’État national reste un acteur important de la régulation de la citoyenneté et que les villes et les échelons locaux de l’État ont acquis une marge de manœuvre par rapport à l’État central dans la mise en place de politiques régulant la citoyenneté à l’échelle locale. Néanmoins, à l’issue de la comparaison, des différences se font jour. Au Québec, l’État central conserve un contrôle important sur les politiques instaurées à l’échelle locale alors que ceci est moins le cas en France. Ces résultats indiquent que le rééchelonnement de l’État est plus fortement institutionnalisé en France qu’au Québec. Les apports de la thèse sont triples. En premier lieu, nous montrons que l’approche institutionnelle du rééchelonnement de l’État permet de mieux décrire les processus à l’œuvre dans différents contextes nationaux que ne le permet la perspective de N. Brenner. En second lieu, nous démontrons que le concept de citoyenneté urbaine ne permet pas de rendre compte des mutations actuelles de la citoyenneté. Enfin, nous montrons que le rééchelonnement de la citoyenneté s’est institutionnalisé en France, dans un État où la conception de la citoyenneté est traditionnellement considérée comme « unitaire », nuançant ainsi cette catégorie classique en science politique.

Protective Liberalization : the state and the Mexican petrochemical industry 1958-2000

This thesis follows and analyses the involvement of both social actors and the state in the industrial transformation of Mexico. While these actors have been key associates in the development of the Mexican economy for decades, with the 1982 debt crisis, and especially after the promotion of a structural reform in 1986, the patterns of their involvement changed. However, this change was more limited than expected, and the state did not abandon its participation in some key industrial sectors. This thesis will demonstrate that the role of the state remained important during the process of change towards an Export-Oriented developmental paradigm, although the state continued to participate in fashioning social relations, it did so in new ways that can be termed “protective liberalization.”
