Le leadership interstitiel, le champ d'action des Amérindiens ou le pouvoir dans la marge : l'exemple de la communauté algonquine de Kitigan Zibi (Québec)

Quel est le champ d’action des Amérindiens dans le contexte politique canadien? Malgré les tentatives de l’État canadien de briser la structure politique traditionnelle des Autochtones en introduisant le système électif et politique du conseil de bande, ceux-ci sont loin d'avoir été des victimes passives. L'étude du leadership interstitiel est la ligne directrice de cette thèse car il est la clé d’une pratique politique « in the cracks » qui confère un pouvoir marginal aux Amérindiens. En s'intéressant aux conditions historiques et sociales de déploiement de l’arène politique en milieu de réserve, il est possible de comprendre la quotidienneté et la contemporanéité de l’exercice du pouvoir au sein d’une population minoritaire fortement politisée. La recherche ethnographique porte sur la politique locale de la communauté algonquine de Kitigan Zibi (Québec). L’analyse des acteurs anishnabeg a montré une variabilité du leadership politique chez les Algonquins et l’existence de différents types de leader malgré l’imposition d’une fonction de chef par la Loi sur les Indiens. Le contrôle des affaires politiques officielles d’une bande par les agents coloniaux, c'est-à-dire les missionnaires et les agents indiens, n’a pas donné lieu à un contrôle total de sa dynamique politique interne et de ses membres. L'enquête de terrain a dévoilé que les diverses manifestations et actions politiques menées par les Anishnabeg s’avèrent être des stratégies du pouvoir dans la marge, une forme quotidienne de résistance face aux nouvelles façons de faire la politique établies par les autorités canadiennes, des ruses et des tactiques employées pour tenter de changer le système formel en remettant en question le pouvoir des Affaires indiennes. La contestation et la résistance ne sont toutefois pas l’unique moteur du leadership et de la politique amérindienne. En fait, le leadership politique chez les Kitigan Zibi Anishnabeg est aussi basé sur diverses représentations (traditionnelles, spirituelles, symboliques) qui ont permis aux Algonquins de préserver une identité politique malgré certaines ruptures et transformations introduites dans leur société par les colonisateurs. Les ambiguïtés, les contradictions et les paradoxes de la quotidienneté politique d’une bande autochtone ne sont pas que le résultat de la rencontre d’un univers politique Autre, mais aussi l’aboutissement de l’évolution et de la reconstruction d’un système sociopolitique traditionnel et de ses dynamiques internes reliées au pouvoir, d’une redéfinition de l’autorité et de la légitimité du politique, de l'essor de leaders nouveau genre pour répondre adéquatement aux exigences politiques de la vie en réserve. La politique de réserve n’est pas une chose concrète mais plutôt une dynamique dans un temps et dans un lieu donné, au chevauchement culturel de diverses traditions politiques et formes d’autorité, au truchement de divers espaces (imposé ou symbolique) et institutions (formelle et informelle). Les Algonquins se renouvellent continuellement politiquement au sein de leur système. Ceci n’est pas un effet de l’acculturation, d’une hybridité ou de la modernité mais relève bien de la tradition. Le rattachement de fonctions et dynamiques traditionnelles à la structure formelle constitue un début de gouvernance « par le bas ». Cette dernière renouvelle de l’intérieur, par l’établissement d’un dialogue, la relation entre les leaders autochtones et les représentants de l’État, ce qui donne aux acteurs locaux une marge de manœuvre. Les Algonquins ont saisi les incompatibilités des deux systèmes – blanc et autochtone – pour définir un nouveau territoire, « in the cracks », qui devient leur domaine d’action. L'analyse de la flexibilité du leadership algonquin, de la vision eurocanadienne du leadership amérindien, de l’usage instrumental des exigences de l’État, des élections et des éligibles contemporains, de l'empowerment des femmes algonquines et du leadership féminin en milieu de réserve, a révélé que le leadership interstitiel est une force politique pour les Kitigan Zibi Anishnabeg. En portant un regard critique sur la politique locale dans le quotidien d'une bande et en incluant les voix autochtones, il est possible d’observer le processus de décolonisation et des formes embryonnaires de pratiques postcoloniales au sein des réserves. Cette recherche a démontré que le chef et les autres leaders sont au cœur de cette dynamique politique dans les marges, de l’essor et de l’émancipation politique de leur bande.

DesignWorld : a tool for team collaboration in high band virtual environments

Current software tools for documenting and developing models of buildings focus on supporting a single user who is a specialist in the specific software used within their own discipline. Extensions to these tools for use by teams maintain the single discipline view and focus on version and file management. There is a perceived need in industry to have tools that specifically support collaboration among individuals from multiple disciplines with both a graphical representation of the design and a persistent data model. This project involves the development of a prototype of such a software tool. We have identified multi-user 3D virtual worlds as an appropriate software base for the development of a collaborative design tool. These worlds are inherently multi-user and therefore directly support collaboration through a sense of awareness of others in the virtual world, their location within the world, and provide various channels for direct and indirect communication. Such software platforms also provide a 3D building and modelling environment that can be adapted to the needs of the building and construction industry. DesignWorld is a prototype system for collaborative design developed by augmenting the Second Life (SL) commercial software platform1 with a collection web-based tools for communication and design. Agents manage communication between the 3D virtual world and the web-based tools. In addition, agents maintain a persistent external model of designs in the 3D world which can be augmented with data such as relationships, disciplines and versions not usually associated with 3D virtual worlds but required in design scenarios.

Application of Dynamic Hysteresis Band Height Control to Improve Output Voltage Transient in Boost and Positive Buck-Boost Converters

This paper presents dynamic hysteresis band height control to reduce the overshoot and undershoot issue on output voltage caused by load change. The converters in this study are Boost and Positive Buck-Boost (PBB) converters. PBB has been controlled to work in a step up conversion and avoid overshoot when load is changed. Simulation and experimental results have been presented to verify the proposed method.

A modified dual-band microstrip monopole antenna

A modified microstrip-fed planar monopole antenna with open circuited coupled line is presented in this paper. The operational bandwidth of the proposed antenna covers the 2.4 GHz ISM band (2.42-2.48 GHz) and the 5 GHz WLAN band (5 GHz to 6 GHz). The radiating elements occupy a small area of 23×8 mm2. The Finite Difference Time Domain method is used to predict the input impedance of the antenna. The calculated return loss shows very good agreement with measured data. Reasonable antenna gain is observed across the operating band. The measured radiation patterns are similar to those of a simple monopole antenna.

Dual-band Decoupling and Matching Network Design for very Closely Spaced Antennas

A practical method for the design of dual-band decoupling and matching networks (DMN) for two closely spaced antennas using discrete components is presented. The DMN reduces the port-to-port coupling and enhances the diversity of the antennas. By applying the DMN, the radiation efficiency can also be improved when one port is fed and the other port is match terminated. The proposed DMN works at two frequencies simultaneously without the need for any switch. As a proof of concept, a dual-band DMN for a pair of monopoles spaced 0.05λ apart is designed. The measured return loss and port isolation exceed 10 dB from 1.71 GHz to 1.76 GHz and from 2.27 GHz to 2.32 GHz.

Normative and critical criteria for iliotibial band and iliopsoas muscle flexibility

Context: The Ober and Thomas tests are subjective and involve a "negative" or "positive" assessment, making them difficult to apply within the paradigm of evidence-based medicine. No authors have combined the subjective clinical assessment with an objective measurement for these special tests. Objective: To compare the subjective assessment of iliotibial band and iliopsoas flexibility with the objective measurement of a digital inclinometer, to establish normative values, and to provide an evidence-based critical criterion for determining tissue tightness. Design: Cross-sectional study. Setting: Clinical research laboratory. Patients or Other Participants: Three hundred recreational athletes (125 men, 175 women; 250 in injured group, 50 in control group). Main Outcome Measure(s): Iliotibial band and iliopsoas muscle flexibility were determined subjectively using the modified Ober and Thomas tests, respectively. Using a digital inclinometer, we objectively measured limb position. lnterrater reliability for the subjective assessment was compared between 2 clinicians for a random sample of 100 injured participants, who were classified subjectively as either negative or positive for iliotibial band and iliopsoas tightness. Percentage of agreement indicated interrater reliability for the subjective assessment. Results: For iliotibial band flexibility, the average inclinometer angle was -24.59 degrees +/- 7.27 degrees. A total of 432 limbs were subjectively assessed as negative (-27.13 degrees +/- 5.53 degrees) and 168 as positive (-16.29 degrees +/- 6.87 degrees). For iliopsoas flexibility, the average inclinometer angle was -10.60 degrees +/- 9.61 degrees. A total of 392 limbs were subjectively assessed as negative (-15.51 degrees +/- 5.82 degrees) and 208 as positive (0.34 degrees +/- 7.00 degrees). The critical criteria for iliotibial band and iliopsoas flexibility were determined to be -23.16 degrees and -9.69 degrees, respectively. Between-clinicians agreement was very good, ranging from 95.0% to 97.6% for the Thomas and Ober tests, respectively. Conclusions: Subjective assessments and instrumented measurements were combined to establish normative values and critical criterions for tissue flexibility for the modified Ober and Thomas tests.

The impact of 'doomed race' assumptions in the administration of Queensland's Indigenous population by the Chief Protectors of Aboriginals from 1897 to 1942

This thesis researched how the anthropological claims of the Aborigines as a 'doomed race' in the decades between 1850 and 1870 became embedded and manifested in pervasive ideologies forming the racist protectionist policies framed in Queensland's Aboriginals Protection and Restriction of the Sale of Opium Act - 1897. Administering the Act was the government appointed Chief Protector of Aboriginals. Conferred with extraordinary powers, Chief Protectors acted and made decisions on behalf of successive governments who displayed little interest in Aboriginal affairs. Amendments to the Act between 1897 and 1939 reflected personal agendas and attitudes towards Aborigines by respective Chief Protectors. Conclusively, the research outcomes show that the 'doomed race' theory became a subterfuge for governments to mask society's racial prejudice against Indigenous peoples and allowed governments to dispossess the Indigenous people of their traditional lands without question from white settlers.

A school by any other name...is still a rock band?

How is your academic institution structured? If you work within a university, then no doubt you are familiar with the use of faculties or perhaps colleges. What about departments or schools? Whatever names or structures are employed, how would you describe the working relationship between academics and professional staff members? As a research scientist and academic over the last twenty years, my appointments have almost always been made through academic departments or schools. In each case, the academic unit has been led by a senior academic manager, such as a chair or head, supported by a dedicated team of professional staff. More recently, however, I have had the opportunity of leading an academic discipline and the experience has led me to reflect more broadly about leadership styles and academic structures within the Australian higher education sector. The written record of this reflection was published last year in the Australian Universities Review (Harkin and Healy, 2013), but I’m pleased to be able to provide a brief synopsis here for the readership of Insights.

Comparison of functionals for metal hexaboride band structure calculations

Density functional calculations of the electronic band structure for superconducting and semi-conducting metal hexaborides are compared using a consistent suite of assumptions and with emphasis on the physical implications of computed models. Spin polarization enhances mathematical accuracy of the functional approximations and adds significant physical meaning to model interpretation. For YB6 and LaB6, differences in alpha and beta projections occur near the Fermi energy. These differences are pronounced for superconducting hexaborides but do not occur for other metal hexaborides.

Ananyi (Going) by Tjupi Band

Research background: Ananyi (Going) is an intercultural music project with lyrics sung in Luritja and English, undertaken in collaboration with the Tjupi Band and producer Jeffrey McLaughlin. The project contributes to cultural maintenance for Australian First Nations peoples, and is informed by prior work in this area by scholars including Peter Dunbar-Hall, Chris Gibson and Karl Neuenfeldt. These existing studies have discussed the complexities of intercultural collaboration, and the types of cultural politics that are involved when Indigenous and non-Indigenous musicians and scholars work together on projects of cultural significance. Critical race theory has also informed the creative work, as a means of interpreting the implicit and explicit discourses of race that arise through intercultural creative practice. The project asked the research question, how can collaborative music making contribute to intercultural understanding and the maintenance of Australian First Nations languages and cultures? Research contribution: The project has identified that recorded popular music is important in the maintenance of Luritja language and culture, and that intercultural collaboration in the areas of digital sound production and distribution can assist with cultural maintenance in both local and national contexts. Research significance: The compact disc was released on the CAAMA Music label, and supported through competitive grants from the Australian Government’s Contemporary Music Touring Grant and the Arnhem Land Progress Association (ALPA). The research context of the work is detailed in Brydie-Leigh Bartleet and Gavin Carfoot 2013. "Desert harmony: Stories of collaboration between Indigenous musicians and university students." International Education Journal: Comparative Perspectives 12 (1): 180-196.

Band gap tunable N-type molecules for organic field effect transistors

A series of four novel n-type molecules has been synthesized. Unlike previous approaches, the end group of these molecules was fixed and the molecular core was varied. The resulting materials were thoroughly analyzed. Electronic properties were derived from photoemission spectroscopy, optical properties were derived with the help of optical spectroscopy, and the structure of thin films on Au(111) was derived by scanning tunneling microscopy (STM). In addition, prototypical organic field-effect transistors (OFETs) (forming n-channels in OFETs) have been fabricated and tested. The correlation between the device performance of the respective OFETs (i.e., electron mobility) and their electronic as well as structural properties was investigated. It turned out that a combination of beneficial electronic and structural properties provides the best results. These findings are important for the design of new materials for future device applications.

A fluorenone based low band gap solution processable copolymer for air stable and high mobility organic field effect transistors

A fluorenone based alternating copolymer (PFN-DPPF) with a furan based fused aromatic moiety has been designed and synthesized. PFN-DPPF exhibits a small band gap with a lower HOMO value. Testing this polymer semiconductor as the active layer in organic thin-film transistors results in hole mobilities as high as 0.15 cm2 V-1 s-1 in air.
