This project focuses on the risk to the operatives and the public arising from hard-shoulder incursions on motorways, which are defined as the temporary violation of this lane by a vehicle travelling on the nearside lane. Even though interest has been raised around safety when stopping on the hard-shoulder, there is no significant research conducted to investigate and quantify this risk. In this EngD project, motorway hard-shoulder accidents were investigated individually from the main traffic lanes to explore the factors affecting their severity and likelihood and identify potential differences using discrete choice and time-series modelling techniques. Based on the safety triangle theory, it was assumed that eliminating the contributory factors for injury accidents would also minimise the risk of hard-shoulder incursions, which were used as a risk indicator. An observation-based survey was conducted to gain initial knowledge on the frequency of incursions within a motorway stretch and also basic conditions that may affect the severity as well. Further to the survey, in order to collect hard-shoulder incursion data automatically, potential vehicle detection solutions were investigated. A radar sensor-based system was identified as the most suitable for this purpose and was adapted to suit the project s requirements. The sensor was installed on a motorway site, following a series of requirements to ensure safe and effective deployment. The data collected from the radar sensor were processed to minimise the errors and then corresponded to the traffic related and environmental data available for the same period of time. Using the Generalised Linear Autoregressive Moving Average model, the final models developed provided the factors that mostly affect the occurrence of hard-shoulder incursions. The main factors are temperature, humidity, traffic composition and average speed on the main carriageway. Using these models it is possible to quantify the risk and forecast when this will be minimised at a particular motorway section at any time. The risk is estimated according to the explanatory variables proposed, by inputting the predictions of these conditions in the model. This model is a tool that may then allow the operatives to be deployed on the network in the safest manner, according to the levels of tolerable risk.

L’éducation spécialisée est confrontée à l’impasse d’articuler les logiques contradictoires. Cet obstacle ainsi que le malaise inhérent à la subjectivité du métier d’éducateur génère de la souffrance qui se traduit par une posture de toute-puissance. La dimension émancipatrice de la relation éducative est étouffée sous les phénomènes de stigmatisation et d’aliénation renforcés par la posture de guidage. Ces difficultés sont repérables au sein des dispositifs d’analyse de la pratique à travers la prégnance de la résolution de problèmes, des entraves à la problématisation et des difficultés à articuler théorie et pratique. Le travail de problématisation vise à explorer les effets de l’usage des incursions théoriques et de la PAC (problématisation par l’articulation des contraires) dans un dispositif d’APP dans lequel l’intervenant adopte une posture clinique. Il s’inscrit dans un cadre théorique mettant en tension l’évaluation, la problématisation et l’émancipation. Cette thèse s’intéresse aux processus en jeu dans la relation éducative, entre le clinicien et le sujet, le sujet et les usagers, en mimésis dans les dynamiques de changement. En ce sens, la méthode clinique s’est imposée pour les rendre intelligibles. L’analyse des entretiens renforce notre hypothèse selon laquelle l’usage des incursions théoriques et de la PAC favorise la problématisation et l’émancipation des sujets tant sur le plan professionnel que personnel. Un phénomène de ricochet a été observé. Les résultats montrent l’importance de l’identification à la posture du clinicien comme mise en scène de l’articulation des contradictions et incarnation du savoir, ainsi qu' un remaniement du rapport au savoir. / Specialized education has to face the difficulty linked to the articulation of contradictory forms of logics. This complexity as well as the uneasiness related to the subjective implication inherent to the profession of educator cause suffering, which leads to an attitude of omnipotence. The emancipating dimension of the educating relationship is neutralized because of phenomens of stigmatisation and alienation. Those difficulties can be distinguished through the devices of analysis of practices, by solving issues, going beyond the obstacles to the process of problematization and beyond the complexity related to the articulation between theory and practice. Adressing those issues aims at exploring the impact of the use of theoretical incursions and of the PAC (problematization through the coordination of contradictory notions) with the help of the APP device, which will be used by the participant in order to adopt a clinical attitude. This work is accomplished within a theoretical framework articulating the evaluating, problematizing and emancipating parts. The clinical method aims at making them intelligible. The analysis of interviews strengthens our hypothesis: using the theoretical incursions and the PAC method is positive in order to problematize and emancipate the patients, as well in terms of professional as personal development. A ripple effect has been observed. The results show how important is the process of identification to the attitude of the clinician, representing thus a way to stage the articulation of contradictory notions as well as the personification of knowledge, and a reorganization of our relationship to knowledge.

Despite decades of scholarly scrutiny, the politico-economic exploits of vikings in and around the Frankish realm (c. 750-940 CE) remain - to a considerable extent - obscured by the constraints of a fragmentary and biased corpus of (near-)contemporary evidence, conveying the impression that these movements were capricious, haphazard, and gratuitous in character. For this reason, rather than selectively assessing individual instances of regional Franco-Scandinavian interaction, the present study approaches the available interdisciplinary data on a cumulative and conceptual level, and combines this with the innovative use of GIS to detect and define overall spatiotemporal patterns of viking activity. Set against a backdrop of continuous commerce and knowledge exchange, this overarching survey demonstrates the existence of a relatively uniform, sequential framework of wealth extraction, encampment, and political engagement, within which Scandinavian fleets operated as adaptable, ambulant polities - or 'hydrarchies'. By delineating and visualising this framework, a four-phased conceptual development model of hydrarchic conduct and consequence is established, whose validity is substantiated by its application to three distinct regional case studies: the lower Rhine-Meuse-Scheldt Basin, the Seine Basin, and the Loire Basin. As well as facilitating the deductive analysis of viking activity for which primary evidence has thus far been ambiguous or altogether absent, the parameters of this abstract model affirm that Scandinavian movements across Francia were the result of prudent and expedient decision-making processes, contingent on exchanged intelligence, cumulative experience, and the ongoing individual and collective need for socioeconomic subsistence and enrichment.

We understand that in the current stage of sophistication in the control society, in a time defined by some as late capitalism or economic globalization, the politics concerned with accommodating, conditioning and piling up the citizens-users of the underground transportation system demand more emphasis and aesthetical elegance than the semiotic strategies have provided up to now. In our research, we state that biopower politics are being applied in the underground transportation system, and those politics seem to be of high relevance not only to its own operations, as well as to the urban configuration. In this sense, we consider the underground transportation system as a state-device. The underground is a fold of São Paulo metropolis in state of metastasis. Our investigative method was anchored by the theoretical references able to provide lights and follow our hypothesis, and also by the ethnographic incursions done in order to gather samples of the life gapsdisplayed over the electric tracks: stereotypes, boredom, lines of escape, dialogues biopolitical samples, in a wider sense. As results of this investigation, we also present single propositions of intervention on the daily life of underground users, with the suggestion of occupying its sonic territory through a project of audio compositions specially produced to be accessed during the underground trips / A pesquisa que desembarca neste formato de ensaio-dissertação partiu do objetivo de investigar os Modos e Modelos de Subjetivação atravessados, envolvidos, forjados e reforçados em meio aos deslocamentos diários de cidadãos no Metrô de São Paulo neste que já é considerado o mais superlotado do mundo, com mais de dez passageiros por metro quadrado em horários de pico. Entendemos que no atual estágio de refinamento da chamada sociedade de controle, em tempos definidos por alguns de capitalismo tardio ou mundialização da economia, as estratégias para acomodação, condicionamento, empilhamento dos cidadãos-usuários do Metrô exigem mais do que pode alcançar o regime de signos ou as estratégias semióticas até então utilizadas com ênfase e certa elegância estética. Justificamos que são aplicadas estratégias do chamado biopoder de relevância ímpar para a operação do Metrô e, em nossa hipótese, de relevância para a própria configuração urbana. Consideramos, desta forma, o Metrô como um dispositivo-Estado. O Metrô é dobra de São Paulo megalópole em metástase. Nosso método investigativo pautou-se no levantamento ou cartografia de referenciais teóricos que pudessem ilustrar e acompanhar a hipótese levantada, bem como de incursões etnográficas em que foi possível colher amostras das chamadas frestas de vida sobre trilhos eléctricos: clichês, tédio, linhas de fuga, diálogos. Enfim: amostras biopolíticas, em seu amplo sentido. Apresentamos também, entre os resultados obtidos, singelas propostas de intervenção no cotidiano dos usuários do Metrô, com a sugestão da ocupação do seu Território Sonoro, por meio de um projeto-piloto de confecção de conteúdos de áudio para serem acessados durante as viagens de Metrô

Thesis (MA)-- Stellenbosch University, 2013. / ENGLISH ABSTRACT: This dissertation is supplementing a documentary film entitled Captor and Captive – the story of Danger Ashipala and Johan van der Mescht (2010), referred to as Captor and Captive, with a duration of 52-minutes. The film follows the story of two soldiers caught up in the disorganized machine of war. Johan van der Mescht, a South African Defence Force (SADF) soldier was captured in 1978 by Danger Ashipala, a South West Africa People’s Organisation (SWAPO) guerilla fighting for Namibian independence. Van der Mescht was held as a prisoner of war (POW) in Angola before being exchanged for a Russian spy, Aleksei Koslov, at Checkpoint Charlie in Berlin in 1982. The main focus of the dissertation is to provide an analysis of representing history through film, with reference to Captor and Captive. It explores the manner in which history can be represented through the medium of film and add value to historical text, as well as historical text adding value to film, and how the two mediums can supplement each other. In this instance, Captor and Captive was produced first and the research conducted was used to inform the dissertation. It briefly discusses the history of documentary film within South Africa; the reality of producing documentary films reflecting on Captor and Captive and the theoretical principles involved in the craft of documentary filmmaking. The dissertation further provides details of the capture of Van der Mescht and his experience as a POW in Angola, against the backdrop of the Border War that waged between 1966 and 1989 in South West Africa (SWA) and Angola. The political landscape and various forces at work within southern Africa during the period of Van der Mescht’s capture are discussed. It also provides detail of the role of Van der Mescht’s captor Ashipala, and the liberation movement SWAPO. With independence in 1990, South West Africa became Namibia and will be referred to as such for the purpose of the dissertation. Mention will be made of other POWs during the Border War, providing a brief comparative analysis of their respective experiences. / AFRIKAANSE OPSOMMING: Die verhandeling is aanvullend tot die dokumentêre rolprent Captor and Captive – the story of Danger Ashipala and Johan van der Mescht (2010). Die rolprent het ‘n 52- minute speeltyd, en daar word daarna verwys as Captor and Captive. Dit handel oor twee soldate wat vasgevang is in die chaos van oorlog. Johan van der Mescht, lid van die Suid Afrikaanse Weermag, is in 1978 gevange geneem deur Danger Ashipala, lid van die Namibiese bevrydingsorganisasie SWAPO. Van der Mescht is as ‘n krygsgevangene in Angola aangehou, en 1982 uitgeruil vir ‘n Russiese spioen, Aleksei Koslov. Die uitruiling het by Checkpoint Charlie in Berlyn plaasgevind. Die verhandeling gee hoofsaaklik ‘n uiteensetting van die manier waarop geskiedenis aangebied word deur die visuele rolprentmedium, met verwysing na Captor and Captive. Die wyse waarop ‘n rolprent waarde kan toevoeg tot historiese teks, en hoe historiese teks op sy beurt weer waarde kan toevoeg tot ‘n rolprent word ondersoek, asook die wyse waarop die twee mediums mekaar kan aanvul. Captor and Captive is vervaardig voor die verhandeling aangepak is, en die navorsing is gebruik ter aanvulling van die verhandeling. Verder word die agtergrond en geskiedenis van dokumentêre rolprente in Suid Afrika kortliks bespreek; die realiteite rondom die vervaardiging van dokumentêre rolprente, met verwysing na Captor and Captive, en teoretiese aspekte betrokke by die vervaardiging daarvan. Die verhandeling verskaf inligting omtrent die gevangeneming van Van der Mescht en sy ondervinding as ‘n krygsgevangene in Angola. Dit word geskets teen die agtergrond van die Grensoorlog (1966 tot 1989) in Suidwes Afrika en Angola. Die politieke omgewing en groeperinge binne Suider Afrika gedurende Van der Mescht se gevangenisskap word bespreek. Verder word inligting oor Ashipala, wat verantwoordelik was vir Van der Mescht se gevangeneming bespreek. Die bevrydingsorganisasie SWAPO, waarvan hy ‘n lid was, word ook bespreek. Suidwes Afrika verander sy naam met onafhanklikheidswording in 1990 na Namibiё, en vir die doel van die verhandeling word daar na Namibiё verwys. Daar word melding gemaak van ander krygsgevangenes gedurende die tydperk van die Grensoorlog, en ‘n vergelyking tussen die ondervindinge van die onderskeie krygsgevangenes word kortliks ondersoek.

Thesis (MA (Political Science. International Studies))--University of Stellenbosch, 2009. / ENGLISH ABSTRACT: Since South Africa’s military intervention in the Angolan conflict twenty years ago, many scholars have written various conflicting accounts on the subject. Why did South Africa become involved in the first place, what made the SADF withdraw, and why did the country decide to become involved once again in a conflict that seemingly did not concern them? What happened at Cuito Cuanavale? These are the questions this study aims to address by drawing on the work of several influential authors. But why the differing narratives? Internal factors such as South Africa’s regional policies during apartheid as well as external factors such as pressure on the Nationalist government from the international arena, all played significant roles in the decision to become more deeply involved in Angola. South African regional policies during apartheid have been regarded in very different ways by various authors which this study will explore. SA’s policies during apartheid were characterised by anti-communism and influenced mainly by the thought that if SA supported a Western ideal, SA would be able to regain some international credit from Western powers. In addition, pressure from international actors increased on SA to protect the southern African region from communist domination. As a result, SA’s second intervention in Angola became prolonged as the clashes between the SADF/UNITA and Angolan/Cuban/Soviet forces grew in intensity. The battle/siege of Cuito Cuanavale is still considered to be the watershed moment that ended the Angolan conflict. The outcome of this battle, however, is still a very controversial subject to this day as some authors claim Cuba won, while others claim the SADF won. At the time there was no surrender. However, establishing exactly who the winner was is very difficult as every party to the conflict has its own ideas about what really happened. The military outcome and political consequences may have influenced this debate. For that reason it is imperative to remember all important influence that various schools of thoughts have on different observers and therefore accounts of the conflict as many of them were written in a time when Cold War and liberation sentiments thrived. Twenty years later is a good time for better informed hindsight. iv / AFRIKAANSE OPSOMMING: Sedert Suid-Afrika se militêre betrokkenheid in Angola twintig jaar gelede, het verskeie kontrasterende verhale van dié konflik die lig gesien. Hoekom het SA in die eerste plek betrokke geraak, waarom het die SAW die eerste keer onttrek en hoekom het die land besluit om weer ’n keer betrokke te raak by ’n konflik wat op die oog af niks met hulle te doen gehad het nie? Wat het by Cuito Cuanavale gebeur? Dit is die vrae wat hierdie studie sal probeer antwoord deur gebruik te maak van verskeie invloedryke outeurs. Maar hoekom die uiteenlopende stories? Interne faktore soos SA se streeksbeleide tesame met eksterne faktore soos internasionale druk op die NP regering, het almal deurslaggewende rolle gespeel in die besluit om dieper betrokke te raak in Angola. Suid-Afrikaanse streeksbeleide gedurende apartheid word anders geïnterpreteer deur verskillende outeurs afhangende uit watter oogpunt hulle skryf, hetsy liberaal of realisties. Streeksbeleide gedurende apartheid was gekenmerk deur anti-kommunistiese sentimente en is hoofsaaklik beïnvloed deur die denke dat indien SA hierdie Westerse ideaal ondersteun het, die land dalk ’n mate van sy reeds kwynende internasionale aansien sou herwin. Hoe dit ook al sy, die druk op SA om Suider Afrika te beskerm teen die kommunistiese aanslag, het geleidelik vergroot vanuit die internasionale arena. Dit is dan ook die rede waarom SA se tweede inval in Angola ‘n meesleurende en uitgerekte saga geword het aangesien botsings tussen die SAW/UNITA alliansie en die Angolese/Kubaanse/Russiese alliansies meer intens en op ’n meer gereelde basis voorgekom het. Die laaste offensief by Cuito Cuanavale word dus steeds gesien as die oomblik wat die einde van die Angolese oorlog ingelui het. Die uitkoms van hierdie geveg/beleg word egter steeds in kontroversie gehul aangesien daar steeds nie konsensus bereik kan word oor wie die eintlike wenners was nie. Sekere outeurs voer aan dat die Kubane sonder twyfel gewen het, terwyl ander beweer dat die SAW gewen het. Op daardie punt was daar egter geen militêre oorgawe nie. Juis om daardie rede is dit baie moeilik om vas te stel wie die eintlike wenner was, aangesien elke betrokke party sy eie idees gevorm het oor wat eintlik gebeur het. Dit is waarom dit belangrik is om te let op die invloed wat verskeie outeurs kan hê op dié onderwerp aangesien baie daarvan geskryf is gedurende ’n tyd toe die Koue Oorlog en bevrydingsoorloë aan die orde van die dag was. Twintig jare later is dalk ’n goeie tyd vir ’n terugblik.

A research report submitted by the Wits School of Arts, Film and Television Department, University of the Witwatersrand, Johannesburg, in partial fulfilment of the requirements for the degree of Masters in Film and Television. Johannesburg 2015 / This research report looks at the politics of memory, commemoration and representation in the new South Africa with a focus on 32-Battalion. The research draws on interviews and testimonies of ex-SADF soldiers who were members of the unit and unpacks how when considering memory and remembering, a multitude of viewpoints emerge. Factors such as the impact of the ideological transition from apartheid to democracy and the resultant impact on ex-SADF soldiers as well as the reshaping of the country’s official history which has been shaped to suit the current political climate, are considered. The research reflects on how these political processes which include exclusions of unwanted histories have affected nation building in South Africa post 1994.

In 1978 the SADF carried out an airborne assault on Cassinga in Southern Angola. The South Africans claimed that Cassinga was a key SWAPO military headquarters, training camp and logistic base. SWAPO claimed it was a refugee camp and that the approximately 600 people who died in the attack were innocent civilians. The SADF said it had dealt SWAPO a significant military blow; SWAPO said the SADF had carried out a brutal massacre of old people, women and children. This dissertation focuses on the military dimensions of the raid, examining first the military situation in southern Angola and northern Namibia at the time, then looking at Cassinga itself before reviewing the airborne capability of the SADF, considering the decision that was made to launch the attack, describing the planning and preparations, the actual assault, a Cuban counter-attack and the extraction of the South African paratroopers. It concludes with the propaganda claims of both sides before assessing the military significance of the action. / History / M.A.

Existing literature identify betrayal as one of the major challenges that former SADF soldiers face in the “new” South Africa, and identify a need for studying the nature and types of betrayal and the effects it has on relationships. This study aimed to describe and interpret former SADF soldier‟s lived experience by focusing on the psychology of betrayal. A cross-sectional qualitative research methodology was used, guided by an interpretive phenomenological approach. Data was gathered through semi-structured interviews, and the data was analysed using Heidegger‟s hermeneutical principles. The identified themes are (1) in the belly of the beast, (2) different agendas, (3) volte-face, (4) keeping the score (5) and just carry on. The findings offer deeper insights and understanding into how former SADF soldiers experience betrayal and the impact it has on their everyday lives. / Psychology / M.A. (Psychology)
