Abstract:

Le Centre International pour le Règlement des Différends relatifs aux Investissements (CIRDI) de la Banque Mondiale et le Centre d'arbitrage de la Cour Commune de Justice et d'Arbitrage de l'OHADA sont des institutions créées par des Etats souverains pour protéger et promouvoir l'investissement privé international. En vue d'atteindre ces objectifs, les Etats fondateurs de ces centres d'arbitrage ont développé des solutions particulières en matière d'exécution des sentences arbitrales. Celles-ci avaient été présentées comme des précédents pouvant servir à la mise au point d'un système international de contrôle et d'exécution des sentences arbitrales. La comparaison des dispositifs d'exécution forcée du CIRDI et de la CCJA met l'accent sur leurs avantages et leurs inconvénients, tout en appréciant la pertinence des solutions qu'ils renferment. De la volonté de restreindre l'intervention des juridictions étatiques caractérisée dans le CIRDI par ce que la doctrine qualifie d'« exequatur simplifié » et pour la CCJA d'« exequatur unique », les présentes conclusions ont pu être tirées: ces procédures d'exequatur rendent désormais autonomes les dispositifs d'exécution du CIRDI et de la CCJA avec cependant une efficacité opérationnelle différente et limitée. Au CIRDI, la procédure d'« exequatur simplifié », mise en oeuvre par chaque Etat contractant, peut entraîner un accueil différent d'une même sentence dans les pays où elle est susceptible d'être exécutée. Or, à la CCJA, la procédure d'« exequatur unique » est organisée par une Cour suprême et indépendante à laquelle les Etats ont donné la compétence exclusive pour accorder l'exequatur. Des limitations apparaissent sur le plan territorial et par rapport au principe de souveraineté. D'un côté, la limitation géographique cantonne l'efficacité de la procédure d'« exequatur unique » au seul espace OHADA ; de l'autre, la souveraineté de l'Etat sur son territoire l'autorise à effectuer un minimum de contrôle sur la sentence arbitrale en référence avec son ordre public. En outre, l'efficacité relevée en amont dans les règles de reconnaissance et d'exécution est diminuée par une conception stricte, voire en recul de l'immunité d'exécution des Etats. Au-delà de ces insuffisances, l'harmonisation des conditions de reconnaissance et d'exécution des sentences arbitrales réalisée par ces deux institutions peut être exploitée utilement. Une procédure uniforme de contrôle, de reconnaissance et d'exécution des sentences arbitrales internationales, dont la supervision serait assurée par une Cour internationale, à laquelle les Etats auront consenti de tels pouvoirs, pourrait être envisagée, pour compléter la Convention de New York sur la reconnaissance et l'exécution des sentences arbitrales étrangères The International Centre for Settlement of Investment Disputes (ICSID) of the World Bank and the Arbitration Centre of the Common Court of Justice and Arbitration of OHADA are institutions created by sovereign states to protect and promote international private investment. In order to achieve these objectives, the founding members have developed special solutions for the enforcement of arbitral awards. These solutions were presented as precedents that can be used for the development of an international System of control and enforcement of awards. The Comparison of ICSID and CCJA forced execution mechanisms emphasizes on their advantages and disadvantages, while appreciating the relevance of the solutions they contain. From the desire to limit the intervention of courts characterized under ICSID by what the doctrine qualifies "simplified exequatur" and under the CCJA's enforcement System "unique exequatur", the following conclusions can be drawn: These enforcement procedures make at this stage, ICSID and CCJA forced execution mechanisms autonomous but with a different and limited operational efficiency. As regards ICSID, the procedure of "simplified exequatur" implemented by each contracting state may lead to a different reception of the same award in the various countries where execution is sought. As regard CCJA, the procedure of "unique exequatur" is organized by a supreme and independent court to which States have given exclusive jurisdiction to grant exequatur. Some limitations exist as regards territoriality and sovereignty. On the one hand the geographical limitation confines the efficiency of the procedure of "unique exequatur" only within OHADA's States; on the other hand the sovereignty of the State in his territory authorizes to perform a minimum control on the arbitral award with reference to public order. The effectiveness observed upstream on the recognition and execution rules of both institutions is reduced by a strict conception, even declining of immunity from execution. Despite these shortcomings the harmonization of the conditions for recognition and enforcement of arbitral awards achieved by these two institutions can be usefully exploited. A uniform procedure of control recognition and enforcement of international arbitral award, under the supervision of an international court, to which States have given such powers could be consider in order to complete the New York Convention for the Recognition and Enforcement of Foreign Arbitral Awards

Abstract:

La collaboration entre la CCJA et les juridictions nationales de cassation, s’effectue dans le contentieux des Actes uniformes. Il met en oeuvre la supranationalité judiciaire de la CCJA qui se manifeste par sa substitution aux juridictions nationales de cassation soulevant des questions liées aux Actes uniformes. Il faut reconnaître que la complémentarité de la collaboration entre la CCJA et les juridictions nationales de cassation dans le recours en cassation devant la CCJA fait ressortir différents des problèmes : une inconstitutionnalité du Traité ou des Actes uniformes dans le processus d’intégration, des inquiétudes dans la procédure de recours en cassation (pas d’auto-saisine de la CCJA, absence de cas d’ouverture à cassation devant la CCJA, formule exécutoire sur les arrêts de la CCJA), l’évocation, la substitution des juridictions nationales de cassation créent devant la CCJA, une controverse dans l’identification du juge compétent dans les procédures de l’AUPSRVE, un risque de conflit de compétence et de lois avec des organisations régionales surtout (UEMOA). Cette collaboration se poursuit entre le juge étatique et la CCJA dans l’arbitrage, c’est le mode de règlement des litiges dans le système OHADA, à cause de l’éthique de l’arbitrage. Ce mode de règlement des litiges dans le mode des affaires ne répond plus au critère du monde des affaires. Même si l’arbitrage OHADA est dual (ad hoc et CCJA), il faut trouver des moyens dans divers droits plus adéquats pour pallier aux divers problèmes évoqués dans le monde des affaires The collaboration between the CCJA and the national courts of cassation, in substance, takes place in the dispute of the Uniform Acts. It implements a judicial supranationality of the CCJA that manifests itself by its substitution to the national courts of cassation of substance raising issues related to the Uniform Act. It must be recognized that the complementarity between the collaboration between the CCJA and the national courts in the cassation appeal before the CCJA brings out different problems : an unconstitutionality of the Treaty even see uniform Acts in the process of integration, Concerns in the procedure upon appeal in cassation (no self-referral of the CCJA, no case of opening to cassation before the CCJA, the executory formula on the judgments of the CCJA), the evocation, the substitution of national courts of cassation, grounds before the CCJA, controversy in identifying the judge competent in the procedures of the AUPSRVE, the risks of conflict of competence and laws with regional organizations ( UEMOA). This collaboration continues between the state judge and the CCJA in arbitration, this is the mode of dispute resolution in the OHADA system, in the face of the ethics of arbitration. This mode of dispute resolution in the business mode no longer meets the criteria of the business world. Even though the OHADA arbitration is dual (ad hoc and CCJA), it is necessary to find ways in various law more adequate to address the various problems evoking for the business world

Abstract:

The grounds for review of arbitration awards are stipulated in section 145 of the Labour Relations Act No 66 of 1995 (hereinafter the “LRA”). However, the Commission for Conciliation, Mediation and Arbitration (hereinafter the “CCMA”) is an organ of state and therefore bound by the Constitution of the Republic of South Africa No 108 of 1996 (hereinafter the “1996 Constitution”). Therefore, the issuing of an arbitration award is bound by section 33 of the 1996 Constitution which requires that administrative should be lawful, reasonable and procedurally fair. It is for this reason that the Constitutional Court (hereinafter the “CC”) in Sidumo & another v Rustenburg Platinum Mines Ltd [2007] 12 BLLR 1097 (CC) held that section 145 of the LRA is suffused by the constitutional standard of “reasonableness”. The CC in Sidumo subsequently confirmed that the standard of review is whether the decision reached by the CCMA commissioner is one that a reasonable decision-maker could not reach. This dissertation seeks to determine how this standard as laid down in Sidumo influenced the courts’ interpretation of the grounds for review and whether there is certainty by the courts on the interpretation of this test.

Full text

Abstract:

The multi-reference correlation consistent composite approach (MR-ccCA) was designed to reproduce the accuracy of more computationally intensive ab initio quantum mechanical methods like MR-ACPF-DK/aug-cc-pCV?Z-DK, albeit at a significantly reduced cost. In this dissertation, the development and applications of the MR-ccCA method and a variant of its single reference equivalent (the relativistic pseudopotential ccCA method) are reported. MR-ccCA is shown to predict the energetic properties of reactive intermediates, excited states species and transition states to within chemical accuracy (i.e. ±1.0 kcal mol 1) of reliable experimental values. The accuracy and versatility of MR-ccCA are also demonstrated in the prediction of the thermochemical and spectroscopic properties (such as atomization energies, enthalpies of formation and adiabatic transition energies of spin-forbidden excited states) of a series of silicon-containing compounds. The thermodynamic and kinetic feasibilities of the oxidative addition of an archetypal arylglycerol ?-aryl ether (?-O-4 linkage) substructure of lignin to Ni, Cu, Pd and Pt transition metal atoms using the efficient relativistic pseudopotential correlation consistent composite approach within an ONIOM framework (rp-ccCA-ONIOM), a multi-level multi-layer QM/QM method formulated to enhance the quantitative predictions of the chemical properties of heavy element-containing systems larger than hitherto attainable, are also reported.

Abstract:

Le Traité sur l’Union Européenne assigne à la Cour de Justice la mission de veiller au respect du droit dans l’application et l’interprétation des traités. A ce titre, elle interprète le droit de l’Union de manière à garantir une application uniforme du droit dans tous les Etats membres. De même, la Cour Commune de Justice et d’Arbitrage (CCJA) est chargée, conformément au Traité relatif à l’Organisation pour l’Harmonisation en Afrique du Droit des Affaires (OHADA), d’assurer dans les Etats Parties, l'interprétation et l'application communes du droit uniforme. Ces cours de justice partagent avec les juridictions nationales l’application judiciaire du droit né des traités. Mais les traités n’ont pas réalisé une fusion du système juridictionnel qu’ils ont créé avec celui des Etats membres et, une hiérarchie juridictionnelle n’a pas été établie entre la Cour de justice et les juridictions nationales. Se pose alors la question des moyens par lesquels ces cours de justice arrivent à imposer une application uniforme du droit dans les Etats membres. Après analyse, on relève qu’à travers l’attribution des pouvoirs juridictionnels, les traités ont conféré une autorité supranationale à la Cour de justice européenne et la Cour de justice de l’OHADA. En plus de cette autorité conférée qu’elles ne se contentent pas d’entretenir à l’égard des juridictions nationales, elles génèrent aussi de l’autorité dans le cadre de leur activité juridictionnelle. Ainsi, ces cours œuvrent pour une meilleure intégration régionale. De leur propre gré, elles n’hésitent pas à adopter des positions impérieuses de plus en plus conquérantes. Ce phénomène fait donc évoluer la conception classique des sources de l’autorité de ces cours. La CCJA bénéficie des prérogatives les plus offensives d’origine textuelle, au contraire de la Cour de justice européenne qui, quant à elle, apparaît plus conquérante dans sa jurisprudence According to the treaty on the European Union, the Court of justice ensures that, in the interpretation and application of the treaties the law is observed. As such, it interprets EU law to make sure it is applied in the same way in all EU countries. In the same way, the treaty of the Organization for the Harmonization of the Business Law in Africa (OHBLA) has conferred to the Common Court of Justice and Arbitration (CCJA) the power to rule on, in the contracting states, the interpretation and enforcement of the treaty. Both regional courts share with national courts the power to apply the law resulting from the treaties.But there has not been a fusion of the judicial system of the member states and the community judicial system. No judicial hierarchy has been established between community courts and national courts. This brings the question of by which means the regional courts can enforce the uniform application of the law in the member states. After analysis, it appears that by granting jurisdictional power, the treaties gave a supranational authority to the European Court of Justice and the CCJA. In addition to the power granted to them, the courts also generate authority through their jurisdictional activities. Thus, the courts work for a better integration of the judicial systems by adopting more and more conquering authoritarian positions. This phenomenon has led to a change in the classical conception of the sources of power of the courts. The CCJA enjoys more power from treaties than the European Court of Justice which is more offensive in case law setting

Abstract:

The Irish crash that began in 2008 has been described as one of the most dramatic economic reversals ever experienced by an industrialised country. There is a strong consensus about the economic roots of the crisis: the country experienced a classic asset bubble. Much more difficult to explain however, is how a mature democracy sleep-walked into a crisis that had so much precedent and in retrospect seems to have been so apparent. The policy decisions made in the boom period must shoulder much of the blame, but they were not created in a vacuum. This thesis systematically examines the discourse on the Irish economy from a broad range of commentators in the years prior to the crash, including international and domestic organisations, academics, the newspapers, and politicians. It demonstrates that key mainstream analysts anticipated how the property boom would end on the basis of estimated fundamental house prices and demand levels. This implicitly assumed that these fundamentals would remain strong as the boom abated, and ignored the potential for a market panic. By contrast, the most prescient analysts relied heavily on international precedent, and recognised that property price falls would be closely correlated with the increase observed during the boom. A key dimension of the discourse was therefore how the lessons of financial history were applied or disregarded.

Abstract:

This thesis deals with the take-up of social security benefits in Britain. It is well documented that not everyone who is entitled to benefits actually claims them. Nontake- up of benefits has been found to be a problem especially for benefits which are means-tested. So, throughout this thesis, we concentrate on Income Support, the main means-tested benefit in Britain. The latest official estimates on the extent of non-takeup (for 1993/94) suggest that up to 1.4 million persons are not receiving close to £1.7 billion of IS in spite of being entitled to it. The main question this thesis addresses IS what are the factors which determine whether an individual will or will not take-up their benefit entitlement? We consider the problem from an economic perspective by constructing suitable models set in both static and dynamic environments. These models provide some interesting insights about the nature of non-take-up. In tum, they also form the basis to a series of econometric models. Previous empirical evidence has shown that the entitlement level itself is one of the key determinants of whether or not an individual will take-up. In addition, it has long been recognized that - due to the complex nature of the benefit system - determining individual entitlements is, in many cases, error-prone with resulting benefit entitlements that are subject to measurement error. Hence, unlike any other studies thus far, we account for the presence of measurement error in the benefit entitlement when modelling the likelihood of take-up. Finally, we shed new light on the dynamics of take-up by using the information contained in our panel data set. In particular, we consider the effect claiming in the past has on the current decision to take-up and how future changes, expected or known with certainty, influence the decision to take-up or not

Abstract:

Ccna [ʃ:na], est une poésie féminine traditionnelle kabyle chantée publiquement lors des fêtes de mariages dans la région d’Ighil n Zekri de Tizi-Ouzou en Algérie. Elle traite essentiellement de la condition socio-affective de la composante féminine des communautés villageoises. Bien qu’elle s’apparente à d’autres types poétiques relevant de la tradition orale kabyle, cette poésie possède des spécificités propres et une originalité expressive, tant du point de vue de son contexte de performance que du point de vue des fonctions qu’elle assure au sein des sociétés productrices. En effet, les cérémonies de ccna donnent lieu à la production d’un espace virtuel de communication et de gestion des conflits qui mérite indéniablement une étude approfondie. Ce projet de recherche est construit autour d’un corpus traduit et annoté, son étude implique nécessairement une approche, à la fois proprement littéraire des textes et anthropologique (acteurs, conditions de création, diffusion et réception) Ccna [ʃ:na], is a female traditional Kabylian poem sung publicly at weddings in the area of Ighil n Zekri in Tizi-Ouzou, Algeria. It mainly deals with women’s socio-emotional conditions in rural communities. Although it is similar to other poetic types in the kabylian oral tradition, this poetry has specificities and a meaningful originality, from the point of view of its performance context as well as from the functions it ensures within the producing societies. Indeed, ccna ceremonies lead to the creation of a virtual space of communication and conflict management that deserves an in-depth study. This research project is built around a corpus translated and annotated, its study necessarily implies an approach, both literary of the texts and anthropological (actors, conditions of the creation, dissemination and reception)

Abstract:

The right to legal representation at internal disciplinary hearings and arbitration proceedings at the Commission for Conciliation, Mediation and Arbitration (CCMA), and bargaining councils, where the reason for dismissal relates to misconduct or incapacity is a topic that is raised continuously and often debated. Despite no amendments to labour legislation pertaining to the issue at hand there was however a recent Supreme Court of Appeal judgment. This judgment alters one’s view and clarifies the uncertainties that were created around Rule 25 of the CCMA rules, it also brings a different perspective to the matter, but it will however continue to ignite significant interest. There is no automatic right to legal representation at disciplinary hearings, at the CCMA, and at bargaining councils where disputes involve conduct or capacity and this is the very reason why it is a contentious matter for all parties to grapple with. The dismissal of an employee for misconduct may not be significant to the employer, but the employee’s job is his major asset, and losing his employment is a serious matter to contend with. Lawyers are said to make the process legalistic and expensive, and are blamed for causing delays in the proceedings due to their unavailability and the approach that they adopt. Allowing legal representation places individual employees and small businesses on the back foot because of the costs. Section 23(1) of the Constitution of the Republic of South Africa, Act 108 of 1996, provides everyone with the right to fair labour practices, and section 185 of the Labour Relations Act 66 of 1995 gives effect to this right and specifies, amongst others, that an employee has the right not to be unfairly dismissed. At internal disciplinary hearings, the Labour Relations Act 66 of 1995 is silent as to what the employee’s rights are with regards to legal representation and the general rule is that legal representation is not permitted, unless the employer’s disciplinary code and procedure or the employee’s contract allows for it, but usually an employee may only be represented by a fellow employee or trade union representative, but not by a legal representative. In MEC: Department of Finance, Economic Affairs and Tourism, Northern Province v Mahumani, the Supreme Court of Appeal held that there exists no right in terms of the common law to legal representation in tribunals other than in courts of law. However, both the common law and PAJA concede that in certain situations it may be unfair to deny a party legal representation. Currently the position in South Africa is that an employee facing disciplinary proceedings can put forward a request for legal representation and the chairperson of the disciplinary hearing will have the discretion to allow or refuse the request. In Hamata v Chairperson, Peninsula Technikon Internal Disciplinary Committee, the Supreme Court of Appeal found that the South African law does not recognise an absolute right to legal representation in fora other than courts of law, and a constitutional right to legal representation only arises in respect of criminal matters.

Abstract:

Includes abstract. Includes bibliographical references. This thesis seeks to identify the test for judicial review of arbitration awards issued by the Commission for Conciliation, Mediation and Arbitration ('CCMA'). Currently, that test is set out in section 145 of the Labour Relations Act 66 of 1995 ('LRA'), read with the Constitutional Court's decision in Sidumo & another v Rustenburg Platinum Mines Ltd & others [2007] 12 BLLR 1097 (CC). In terms of Sidumo, section 145 of the LRA has been suffused by the standard of reasonableness, consistently with the right to just administrative action found in section 33 of the Constitution of the Republic of South Africa, 1996 ('the Constitution'). In search of a clear formulation of the test, an extensive examination of South African case law on the subject is undertaken. Thereafter, relevant principles of judicial review in South Africa in the administrative sphere generally are considered. Finally, an assessment of Canadian case law and commentary in this field is conducted. The conclusion to this thesis proposes a revised test for review of CCMA awards. The principal research findings begin by recognising the significance of efficiency, accessibility, flexibility and informality to ensuring fair and efficacious labour dispute resolution. The implication of this is that the test for review of CCMA awards should not be too exacting. Still, section 33 of the Constitution cannot be ignored and a broader ambit of review may therefore be necessary in certain instances. In fact, to maintain legal certainty, intrusive review may sometimes be crucial. These factors must be balanced when formulating a reliable and practical approach to review of CCMA awards. A key finding of this thesis is that – ostensibly due to the complexity of doing so – the Labour Courts have struggled to apply the current test for review consistently, fairly or predictably.

Abstract:

This research examines the effects of evaluations, beliefs, subjective norms, and perceived behavioral control on the contractor's decision intention to recover used CCA lumber. The purpose of this research was to determine the factors that affect recovery. This research proposes that a contractorâ s decision intention to recover is affected by evaluations, beliefs, subjective norms, and perceived barriers to recovery. The study included a mail questionnaire that was sent to over 2,800 contractors. The questionnaire was used to collect both demographic data and an evaluation of the factors believed to affect the recovery of CCA treated lumber. Data was collected primarily through the mail survey, where participants rated the factors believed to affect the recovery of spent CCA lumber. Extrapolation indicates that nearly 2.4 million cubic meters of treated lumber were removed in 1999 from the demolition of decks. It was also discerned that only two of the respondents recovered used CCA lumber on a full-time basis. Additionally, there appears to be a lack of knowledge regarding the chemical components of CCA treated lumber, the proper disposal methods, and handling of the product. This has profound strategic implications for not only the wood treating industry but other industries as well. The second phase of the research utilized ordinary least squares regression and a structural equation modeling program to model the factors concerning the contractors' decision intention to recover. The findings indicate that contractor beliefs and components of perceived behavioral control are the primary drivers in the contractor's decision intention to recover. Regarding beliefs, the findings indicate that contractors have a minimal belief that the recovery of the CCA lumber is necessary. This indicates that a marketing communications program should be developed to address the necessity and benefits of recovery. Recovery facilities and programs were found to be nonexistent and will have to be developed in order to facilitate recovery. Concerning programs, the overwhelming response was that some type of financial incentive would have to be incorporated to initiate recovery. In conjunction with the development of programs, recovery facilities will have to be developed that are convenient for the contractor to dispose of the used lumber. Ph. D.

Abstract:

Ultrasound is a commonly used imaging modality in diagnosis and pre-operative assessment of breast masses. However, radiologists often find it very difficult to correctly size masses using conventional ultrasound images. Consequently, there exists a strong need for more accurate sizing tools to avoid either the removal of an over-estimated amount of tissue or a second surgical procedure to remove margins involved by tumour not removed in the primary operation. In this thesis, we propose a new method of processing the backscattered ultrasound signals from breast tissue (based on the Fourier spectral analysis) to better estimate the degree of echogenicity and generate parametric images where the visibility of breast mass boundaries is improved (SPV parametric image). Moreover, an algorithm is proposed to recover some anatomical structures (particularly, Cooper’s ligaments) which are shadowed during the image acquisition process (LWSPV parametric image). The information from both algorithms is combined to generate a final SPV+LWSPV parametric image. A 20-case pilot study was conducted on clinical data, which showed that the SPV+LWSPV parametric image added useful information to the B-mode image for clinical assessment in 85% of the cases (increase in diagnostic confidence in at least one boundary). Moreover, in 35% of the cases, the SPV+LWSPV parametric image provided a better definition of the entire boundary. Note that the radiologist knew the final diagnosis from histopathology. In addition, the SPV+LWSPV method has the advantage that it uses the I/Q data from a standard ultrasound equipment without the need for additional hardware. On the basis of these facts, we believe there to be a case for further investigation of the SPV+LWSPV imaging as a useful clinical tool in the pre-operative assessment of breast mass boundaries.

Abstract:

General relativity describes gravity in terms of an interacting massless spin-2 field - the graviton. This 100-year-old theory has been spectacularly successful in explaining observations. However, theoretical exploration and the cosmological constant problem motivate the study of alternative theories of gravity. Recently, there has been great progress in understanding theories that give the graviton a mass. This thesis considers several aspects of these massive spin-2 effective field theories and related theories. These theories are first studied from the perspective of scattering amplitudes. The most general 2 → 2 scattering amplitude is constructed for theories containing a single massive graviton or vector. These amplitudes are then used to find the highest strong coupling scales in such theories, assuming a particular scaling of fields and momenta. Generalisations to include additional fields and self-interactions for massive higher-spin fields are also discussed. Constraints that arise from the existence of an ultraviolet completion are then studied. It is shown using dispersion relation arguments that the pseudo-linear massive spin-2 theory cannot admit an analytic, Lorentz-invariant, and unitary ultraviolet completion, but that such completions are not ruled out for massive vector theories. The behaviour of massive spin-2 theories under dimensional reduction is also explored. Stability conditions and the lower-dimensional spectrum are derived for the Kaluza-Klein dimensional reduction of a partially massless graviton and a massive graviton on an Einstein product manifold. Additionally, the nonlinear dimensional reduction of the zero modes in dRGT massive gravity is shown to produce a mass-varying massive gravity theory. Lastly, attempts to construct a version of unimodular gravity containing a massive graviton are discussed. A candidate theory is proposed and is shown to have pathologies. Dimensional reduction is then used to generate massive spin-2 theories with noncanonical kinetic terms and auxiliary fields. These theories are shown to be equivalent to the Fierz-Pauli theory, which provides further evidence for the uniqueness of the kinetic term used in dRGT massive gravity.

Abstract:

Psychosis encompasses a constellation of symptoms that have far-reaching social, physical and functional consequences for sufferers. One of the key clinical concerns in the management of psychotic illnesses is the risk of suicide, which is greatest in the early stages of psychosis. Hopelessness is consistently associated with risk for suicide but as a concept it is not well defined and is not specific enough to be of use in prediction of suicide. Future-directed thinking, particularly regarding positive future events, constitutes an aspect of hopelessness that is closely associated with risk for suicide. This study employed the Future Thinking Task to investigate whether future-directed thinking in first episode psychosis is significantly different from that of matched controls in performance or content, and to clarify the nature of its association with suicide risk in this patient group. In addition, the association of future-directed thinking with the negative symptoms of psychosis was investigated. The results showed that individuals with psychosis were impaired in future-directed thinking globally, particularly with respect to the coming year. Specific deficits were shown in the domains of relations with other people and personal development and understanding. Associations were shown between future-directed thinking and suicide, and reduced positive future-directed thinking was shown to be strongly associated with increased severity of negative symptoms. The results suggest avenues for novel interventions to improve hopelessness, suicide risk and the severity of negative symptoms in psychotic illness, and thereby improve functional outcomes.

Abstract:

Stockholm County is currently implementing climate change adaptation, making it essential to distinguish the priorities being made. Previous research has suggested that social dimensions of climate change adaptation in cities, especially in the Global North, are largely ignored. Therefore, this thesis aims to identify how social dimension issues of current local Climate Change Adaptation [CCA] in Stockholm County is perceived by CCA-practitioners and provide an overall understanding of how current local Climate Change Adaptation [CCA] materializes in Stockholm County. Five civil servants working as environmental planners/strategists were interviewed and part of a semi-structured interview study, which was analyzed through thematic analysis and an intersectional framework. The results suggest that current local CCA prioritizes specific climate hazards (Floods and different erosion- related hazards), certain buildings (new developments), and certain evaluations (technical). In addition, heatwaves, existing built environments, and social dimension assessments were shown to be of less focus in current local CCA. The results from the intersectional franmework showed that specific identity categories are considered in certain climate hazards, specifically in heatwaves that have clear health outcomes compared to the other hazards. It also shows that gender seems to be the least explored identity category of vulnerability in current local CCA-practice.

Abstract:

Clostridium perfringens is a significant human pathogen, causing 250,000 cases of food poisoning in addition to several thousand potentially lethal cases of gas gangrene each year in the United States. Historically, work in this field has centered around toxin production, as C. perfringens can produce over 13 toxins. This work expands the knowledge of the starvation-response of C. perfringens, which includes several potential virulence factors, sporulation, motility and biofilm formation. Sporulation protects cells from a variety of stresses, including starvation. Efficient sporulation requires the transcriptional regulator CcpA, mediator of catabolite repression. Sporulation is repressed by glucose, but, surprisingly, in a CcpA-independent fashion. C. perfringens cells in a biofilm are resistant to a number of environmental stresses, including oxygen and antibiotics. Biofilm formation is repressed by glucose, and other carbohydrates, independently of CcpA. Gliding motility, a type four pili (TFP)-dependent phenomenon, affords C. perfringens with a mechanism for moving across a solid surface in response to carbohydrate starvation, while carbohydrates supplementation at high levels delay the initiation of the motility response. CcpA is required for the proper initiation of motility, a ccpA-C. perfringens strain showed a considerable increase in the time to initiation of motility on lactose and galactose, and was unable to move at all in the presence of glucose. Gliding motility represents the most significant finding of this work. TFP were previously undescribed in any Gram-positive bacterial species, and this work produced genetic evidence suggesting their presence in all members of the clostridia, and physical evidence for TFP-dependent gliding motility in a second species, C. beijerinckii.

Abstract:

The right to legal representation at labour proceedings of an administrative or quasi-judicial nature is not clear in our law, and has been the subject of contradictory debate in the South African courts since the1920’s. Despite the ambiguities and uncertainty in the South African common law, the statutory regulation of legal representation was not comprehensively captured in labour legislation resulting in even more debate, especially as to the right to be represented by a person of choice at these proceedings in terms of the relevant entrenched protections contained in the Bill of Rights. The Labour Relations Act 12 of 2002 (prior to amendment) is silent on the right to representation at in-house disciplinary proceedings. Section 135(4) of Act 12 of 2002 allows for a party at conciliation proceedings to appear in person or to be represented by a director or co employee or a member or office bearer or official of that party’s registered trade union. Section 138(4) of the same Act allows for legal representation at arbitration proceedings, but subject to section 140(1) which excludes legal representation involving dismissals for reasons related to conduct or capacity, unless all parties and the commissioner consent, or if the commissioner allows it per guided discretion to achieve or promote reasonableness and fairness. The abovementioned three sections were however repealed by the amendments of the Labour Relations Act 12 of 2002. Despite the repealing provision, Item 27 of Schedule 7 of the Amendment reads that the repealed provisions should remain in force pending promulgation of specific rules in terms of section 115(2A)(m) by the CCMA. These rules have not been promulgated to date. The common law’s view on legal representation as a compulsory consideration in terms of section 39 of the Constitution 108 of 1996 and further a guidance to the entitlement to legal representation where legislation is silent. The common law seems to be clear that there is no general right to legal representation at administrative and quasi judicial proceedings. If the contractual relationship is silent on representation it may be permitted if exceptional circumstances exist, vouching such inclusion. Such circumstances may include the complex nature of the issues in dispute and the seriousness of the imposable penalty ( for example dismissal or criminal sanction). Some authority ruled that the principles of natural justice supercede a contractual condition to the contrary which may exist between employer and employee. The courts did however emphasize the importance and weight of the contractual relationship between the parties in governing the extent of representation at these proceedings. Since 1994 the entrenched Bill of Rights added another dimension to the interpretation of rights as the supreme law of the country. On the topic of legal representation and within the ambit of the limitation clause, three constitutionally entrenched rights had to be considered. The first is the right to a fair trial, including the right to be represented by a practitioner of your choice. Authority reached consensus that this right, contained in section 35 of the Constitution Act 108 of 1996 is restricted to accused persons charged in a criminal trial. The second protection is the entitlement to administrative procedure which is justifiable and fair (This extent of this right is governed y the provisions of the Promotion of Access to Administrative Justice Act 3 of 2000) and thirdly the right to equality before the law and equal protection by the law. In conclusion, the Constitution Act 108 of 1996 upholds the law of general application, if free and justifiable. Within this context, the Labour Relations Act 66 of 1995 allows for specific representation at selected fora, and the common law governs legal representation post 1994 within the framework of the Constitution. The ultimate test in considering the entitlement to legal representation at administrative and quasi judicial proceedings will be in balancing the protection of the principle that these tribunals are masters of their own procedure, and that they may unilaterally dictate the inclusion or exclusion of representation at these proceedings and the extent of same, as well as the view of over judicialation of process by the technical and delaying tactics of legal practitioners, against the wide protections of natural justice and entrenched constitutional protections.

Abstract:

Os postes de madeira da rede de distribuição de energia elétrica são tratados com preservantes para aumentar sua vida útil. Dentre os diversos tipos de preservantes de madeira disponíveis no mercado, o mais utilizado é o arseniato de cobre cromatado (CCA), tendo em vista a sua elevada eficiência para preservar a madeira. A presença de metais nestes preservantes exige uma destinação adequada ao fim da vida útil do poste. O presente estudo propõe a utilização do processo de pirólise como uma alternativa para a destinação final dos postes de madeira removidos da rede de distribuição de energia elétrica. A pirólise da madeira tratada com CCA promove a liberação de compostos voláteis perigosos devido à presença dos metais (Cr/Cu/As) em sua composição. Com o intuito de minimizar estas emissões, reagentes de baixo custo (a base de cálcio) podem ser utilizados durante o processo pirolítico. Neste trabalho, foram avaliados os efeitos de diferentes parâmetros de operação (temperatura, tempo de isoterma, taxa de aquecimento, razão madeira/CaO e velocidade superficial) sobre a retenção dos metais no char da madeira tratada com CCA, bem como a influência dos compostos de cálcio sobre o poder calorífico do gás combustível gerado no processo de pirólise. A caracterização da madeira tratada com CCA indicou diferenças na composição química das frações testadas (C1-alburno externo, C2-alburno interno e C3-cerne), especialmente no teor de metais. As análises para a determinação da distribuição de metais indicaram que a concentração de compostos metálicos tende à zero na linha central do poste, de forma que a elevada concentração de metais está localizada na fração externa do poste. Na análise imediata, foi observado um teor mais elevado de cinzas na fração externa da madeira. Na Espectroscopia no Infravermelho com Transformada de Fourier (FTIR) a madeira com CCA apresentou bandas similares a de uma biomassa convencional. Na Análise Termogravimétrica (TGA), observaram-se picos próximos a 276 e 354 ºC, referentes à degradação térmica das hemiceluloses e da celulose, respectivamente. A energia de ativação determinada pelo método de Kissinger foi próxima a 156 kJ·mol-1. A Ea média calculada no método de Flynn-Wall-Ozama foi de aproximadamente 153 kJ·mol-1 para C1, 182 kJ·mol-1 para C2 e 170 kJ·mol-1 para C3. Os mecanismos de reação no estado sólido verificados no método de Criado foram comandados, em sua maioria, por processos de difusão. Sob condições controladas de operação, (temperatura, tempo de residência e vazão de ar) o carbonato de cálcio (CaCO3) foi calcinado visando a obtenção de óxido de cálcio (CaO) com elevada área superficial. Os ensaios preliminares de calcinação indicaram que o CaO com maior área superficial foi obtido a 850 ºC com um tempo de residência de 5 min. Na primeira série de ensaios de pirólise verificou-se que à medida que CaO foi adicionado ao sistema, a emissão de metais e a produção de óleo foram inferiores. No segundo lote dos ensaios de pirólise, os efeitos preponderantes para a retenção dos metais no char foram a granulometria elevada das partículas, a adição de CaO e a taxa de aquecimento. Devido à adição de CaO, obteve-se menor concentração de CO2 e foi produzido um gás combustível com poder calorífico próximo a 25 MJ·Nm-3.

Among the various types of wood preservatives available on the market, the most used is the chromated copper arsenate (CCA), due to its high efficiency for preserving wood. The presence of metals in these preservatives requires proper disposal at the end of pole life. This study proposes the use of pyrolysis process (under controlled conditions) as an alternative to wooden poles disposal after removed from the electricity distribution network. The pyrolysis of CCA treated wood promotes the release of dangerous volatile compounds due to the presence of metals (Cr/Cu/As) in its composition. In order to minimize these emissions, low cost reagents (based on calcium) can be used during the pyrolytic process. In this work, the effect of different operating parameters (temperature, residence time, heating rate, wood/CaO ratio and superficial velocity) on the retention of metals in the char was evaluated, as well as the influence of calcium compounds on the calorific value of the fuel gas generated in the pyrolysis process. The characterization of CCA treated wood indicated differences in the chemical composition of the tested fractions (C1-sapwood, C2- outer core and C3-cord), especially in the metal content. The metals distribution analysis indicated that the concentration of metallic compounds tend to zero at the center of the pole, so the high concentration of metal is located on the outer portion. In the proximate analysis, a higher ash content on the outer portion was observed. Fourier Transform Infrared Spectroscopy (FTIR) showed bands very similar to a conventional biomass. In Thermogravimetric Analysis (TGA) peaks centered at 276 and 354 ºC were observed, relating to thermal degradation of hemicellulose and cellulose respectively. The activation energy determined by the Kissinger method was approximately 156 kJ·mol-1. The mean activation energy by the Flynn-Wall-Ozama method was 153 kJ·mol-1 for C1, 182 kJ·mol-1 for C2 and 170 kJ·mol-1 for C3. The degradation reaction mechanism determined by using the Criado is mostly controlled by diffusion processes. Under controlled operating conditions (temperature, residence time and air flow) calcium carbonate (CaCO3) was heated in order to obtain calcium oxide (CaO) with a higher surface area. Preliminary tests indicated that the calcination of CaO with greater surface area was obtained at 850 ºC with a residence time of 5 min. In the first series of pyrolysis tests, as CaO was added to the system, lesser metals emission and oil yield were observed. In the second set of pyrolysis tests, the relevant effects identified on the retention of metals was the high particle size of the wood, the addition of CaO and the heating rate. Due to the addition of CaO, the CO2 concentration was reduced and it was produced a combustible gas with a calorific value close to 25 MJ·Nm-3.

Abstract:

The amount of CCA treated wood being removed from spent residential decks is increasing at a tremendous rate. While most spent CCA treated wood is being disposed in landfills, further useful and environmentally beneficial alternatives have to be met. This research estimated the percentage of recoverable lumber from spent CCA decks that can be recycled into other usable products. Six residential decks were removed from service, by either demolition or deconstruction procedures. It was found that 86% of the CCA treated wood from the residential decks could be recovered as reusable CCA treated lumber. It was also found that deconstruction of a residential deck, rather than demolition, was not a factor in the volume of CCA treated wood recovered. Chemical and mechanical properties of the removed CCA treated wood were also analyzed. The chemical retention of the deck material proved that most of the spent CCA treated wood could be used in above ground applications. The stiffness of spent CCA treated wood from residential decks was approximately equal to that of recently treated CCA wood. The strength properties were slightly lower than recently treated CCA wood probably due mainly to physical and climatic degradation. Products were then produced that could be successfully utilized by recycling centers or community and government organizations. Products manufactured included, pallets, picnic tables, outdoor furniture, residential decks, and landscaping components. Waste management, recycling, and government organizations were interviewed to determine what markets and barriers exist for recycled CCA treated products. Most landfill and recycling facilities do not currently sort or recycle CCA treated wood, citing the main reason as a lack of a viable market. Potential users were interested in the material but citied they did not know where to locate the material. A communication barrier exists between the waste management industry, recyclers, and users; which is preventing the successful recycling of CCA treated wood from spent residential decks.

Abstract:

Chromated copper arsenate (CCA) is a biocidal chemical used by the wood preservation industry to extend the service life of wood products. CCA is currently the most commonly used wood preservative in British Columbia. Environmental concerns regarding the fate of CCA solutions accidentally released or chronically spilled to unpaved ground at wood preservation facilities has led to the present investigation on the retention and release of CCA constituents in soils. Batch and column tests were used to evaluate the adsorption and desorption of arsenic, chromium and copper in several B.C. soils. Batch tests were carried out using varying concentrations of CCA and individual arsenic, chromium and copper solutions. Migration of arsenic, chromium and copper in a soil column following application of a single slug dose of 2% CCA solution was investigated. Continuous leach column experiments were also conducted to evaluate adsorption of CCA constituents in soils. The column soils were sectioned and subjected to a sequential extraction procedure following influent CCA solution breakthrough to determine the partitioning, mobility and availability of As, Cr and Cu. Results from the adsorption experiments were used to identify important soil characteristics influencing the attenuation of CCA in the subsurface environment. Adsorption isotherm data was found to be well described by the Freundlich equation. The Fe and Al amorphous and crystalline hydrous oxide component of the soils studied was highly correlated with arsenic adsorption while the percent organic carbon was significantly correlated with chromium and copper retention in the soils. The clay content of the soils was poorly correlated with retention of CCA constituents in the soils studied. Desorption of arsenic, chromium and copper from soils previously equilibrated with CCA solutions showed that the extent of metal release is dependent on the amount of metal retained. At high initial CCA solution concentrations chromium was desorbed to a greater extent than arsenic or copper. This result suggests the following order for mobility of CCA constituents in the soils: chromium > copper > arsenic. Chromium, and to a lesser extent copper, adsorption was lower in CCA equilibrated batch tests than in single solute batch tests, particularly at high initial metal solution concentrations. Arsenic adsorption was not affected by the presence of codissolved solutes in CCA solution. The migration of arsenic, chromium and copper in a soil column following application of a single dose of 2% CCA revealed that chromium was the most mobile of the CCA constituents. Breakthrough curve plots showed that arsenic was the most strongly retained CCA constituent in both soils tested. Copper was also strongly retained in the soil columns however complete breakthrough was achieved indicating that the soils had reached a finite capacity for copper retention. Chromium was again the most weakly held CCA constituent in the continuous leach column test. Partitioning of the metals in the column soils showed that arsenic, chromium and copper were largely associated with the ammonium oxalate extractable fraction. Only copper was found to have a significant amount of retained metal in the exchangeable pool. The results suggest that environmental monitoring at CCA wood preservation facilities should focus on the potential for chromium migration in the subsurface.

Abstract:

South Africa’s employment law has undergone more frequent and dynamic changes than any area of the law, in recent years. The ability of employers and employees to regulate their respective rights and duties vis-à-vis each other by independent agreement has been progressively whittled down by statutory intervention. In so limiting the capacity of parties to the employment relationship to regulate the nature of their relationship, South Africa has followed development in Western industrialised nations. Against this background, the drafters of the Labour Relations Act1 (LRA), as amended, proposed a comprehensive framework of law governing the collective relations between employers and trade unions in all sectors of the economy. The LRA2 created a specialised set of forums and tribunals to deal with labour and employment related matters. It established Bargaining Councils, the Commission for Conciliation Mediation and Arbitration (CCMA), the Labour Court (LC) and the Labour Appeal Court (LAC). It also created procedures designed to accomplish the objective of simple, inexpensive and accessible resolution of labour disputes. In redesigning labour law, the legislature decided that some disputes between employers and employees should be dealt with by arbitrators and others by judges. It is this distinction that resulted in the creation of the CCMA and the Labour Court to perform arbitration and adjudication respectively. The result of adjudication is generally subject to appeal to a higher court. The result of arbitration is generally subject to review. Arbitration was given statutory recognition in South Africa by the Arbitration Act3. That Act provides a framework within which parties in dispute may if they wish appoint their own “judge” and supply him or her with their terms of reference tailored to their needs. With the foregoing in mind, the purpose of this work is the provision of a selection of landmark cases that dealt with the review function of CCMA awards. This selection 1 Act 66 of 1995 as amended comprises of landmark judgments of the different courts of the land. The study uses, as it departure point, legislative framework to elicit the extent to which review is extended to the litigants. Apart from looking at the legislative provisions towards review grounds, reference is made to specific landmark judgments that have an effect on this subject in order to provide a comprehensive and explicit picture of how CCMA arbitration awards may be taken on review. This study focuses on substantive law developed by the Labour Court, High Court, Supreme Court of Appeal and finally the Constitutional Court. This is informed by the very nature and scope of the study because any concentration on procedural and evidentiary aspects of review could lead to failure to achieve the objectives of the study. It looks at specific South African case law, judgments of the courts and the jurisprudence in the field of employment law so that the reader is presented with a clearer picture of recent developments in addressing review of arbitration awards. The concluding remarks are drawn from a variety of approaches used by the authorities in the field of employment law in dealing with review of CCMA arbitration awards and issues for further research are highlighted.

Abstract:

CCA-adding enzymes synthesize and maintain the C-C-A sequence at the tRNA 3'-end, generating the attachment site for amino acids. While tRNAs are the most prominent substrates for this polymerase, CCA additions on non-tRNA transcripts are described as well. To identify general features for substrate requirement, a pool of randomized transcripts was incubated with the human CCA-adding enzyme. Most of the RNAs accepted for CCA addition carry an acceptor stem-like terminal structure, consistent with tRNA as the main substrate group for this enzyme. While these RNAs show no sequence conservation, the position upstream of the CCA end was in most cases represented by an adenosine residue. In tRNA, this position is described as discriminator base, an important identity element for correct aminoacylation. Mutational analysis of the impact of the discriminator identity on CCA addition revealed that purine bases (with a preference for adenosine) are strongly favoured over pyrimidines. Furthermore, depending on the tRNA context, a cytosine discriminator can cause a dramatic number of misincorporations during CCA addition. The data correlate with a high frequency of adenosine residues at the discriminator position observed in vivo. Originally identified as a prominent identity element for aminoacylation, this position represents a likewise important element for efficient and accurate CCA addition.

Este trabalho tem como objetivo mostrar que o discurso quotidiano não se apaga frente à afasia, ao contrário, está presente nas atividades desenvolvidas no Programa de Linguagem do CCA, cujos recursos metodológicos (o uso de agenda individual e coletiva, bem como a retomada conjunta do noticiário da semana), contribuem decisivamente na construção tanto de um quotidiano, quanto de um discurso quotidiano do próprio Centro.O CCA é um espaço de interação entre pessoas afásicas e não afásicas que surgiu em 1990, não apenas para dar assistência clínico-terapêutica a sujeitos afásicos a partir de uma abordagem clínica e reabilitadora diferente dos moldes tradicionais, mas também desenvolver atividades de ensino, pesquisa e docência nos estudos entre linguagem, cérebro e cognição.Sirvo-me, na orientação teórica deste trabalho, da concepção enunciativo-discursiva de conversa quotidiana proposta por Mattos (1998:15), segundo a qual a conversa é um ato social materializado pelo discurso enquanto prática social que mantém em funcionamento ¿as relações interpessoais , isto é, ela não se dá ¿em vão¿, mas para estabelecer, conservar, transformar as relações entre amigos, parentes, fregueses, conhecidos e desconhecidos, etc¿. Sendo a conversa quotidiana o lugar de transformações das relações entre sujeitos, ela parece transformar as relações dos sujeitos presentes no espaço discursivo do CCA, numa espécie de comunidade de fala. Essa transformação ocorre através da formação do ¿common ground¿, ou seja, o lugar comum que leva os sujeitos a terem uma identificação enquanto grupo social. No caso do CCA, é provável que o ¿common ground¿ seja instituído pelo discurso quotidiano, que é propriamente a prática em comum dos sujeitos no espaço de interação e convivência do Centro Abstract:This study is about the description of the quotidian conversation and the analysis of the quotidian discourse at ¿Centro de Convivência de Afásicos¿, located in the physical space of ¿Instituto de Estudos da Linguagem¿ (IEL), from ¿Universidade Estadual de Campinas¿. This work has the objective to show that the quotidian discourse doesn¿t disappear to the aphasia, on the contrary, it is present in the activities developed in the language program of ¿CCA¿, whose methodological resources, (the usage of individual and collective agenda as well as the joint resumption of the weekly news), contribute decisively to the construction of either a quotidian and a quotidian discourse of the own Center.¿CCA¿ is a space for interaction between aphasic and non-aphasic people, created in 1990, not just to give clinical and therapeutic assistance to the aphasic through a clinical and rehabilitative approach different from the traditional patterns, but also to develop teaching activities, research and teaching in the studies involving the language, the brain and the cognition. I make use of the proposition and discursive conception of quotidian conversation, in the theoretical orientation of this work, proposed by Mattos (1998:15), according to whom conversation is an act materialized by the discourse while social practice that makes the interpersonal relations go on in operation, that is, it doesn¿t show up for no reason, but to establish, maintain, transform the relations among friends, relatives, customers, acquaintances and non-acquaintances, etc. For the quotidian conversation is a place for transformation of relations among subjects, it seems to transform the present subjects¿ relations in the discursive space of ¿CCA¿, in a kind of speaking community. This transformation occurs through the ¿common ground¿ formation, that is, the common place that leads the subjects to have identification as a social group. In the case of ¿CCA¿, it is probable that the ¿common ground¿ will be instituted by the quotidian discourse, that is exactly the subjects¿ common practice in the conviviality and interactive space in the Center Mestrado Linguistica Mestre em Linguística

Abstract:

Mestrado em Toxicologia O Crómio-Cobre-Arsenato (CCA) é um protector da madeira, contendo crómio, cobre e arsénio. Apesar de em 2002, a agência de protecção ambiental (EPA) ter limitado a utilização da madeira tratada com CCA, a contaminação do ambiente e o perigo para a saúde pública permanece, devido à grande durabilidade desta madeira. O principal objectivo deste trabalho foi analisar a toxicidade aguda do CCA em ratinhos. O desenvolvimento e optimização de uma metodologia de quantificação do arsénio e do crómio total nos rins de ratinhos foi também um outro objectivo. Realizaram-se experiências para caracterizar os efeitos causados pelo CCA e pelos compostos individuais (pentóxido de arsénio – As2O5) e (trióxido de crómio – CrO3) em vários órgãos de ratinhos. Os animais foram divididos em dezasseis grupos, correspondendo a diferentes tempos de exposição. Os grupos de tratamento receberam uma injecção subcutânea (0,3 mL) de CCA, CrO3 e As2O5. Aos animais controlo foi administrado o veículo (soro fisiológico). Após 14h, 24h, 48h e 96h procedeu-se ao abate dos animais e à remoção dos rins, timo, fígado, baço, testículo e epidídimo. Realizaram-se análises histológicas e histoquímicas dos rins de animais provenientes de todos os grupos. Procedeu-se a estudos de citometria de fluxo (FCM) para a análise do ciclo celular. Efectuou-se ainda um estudo preliminar para determinação da actividade da catalase (CAT) e da glutationa – S – transferase (GST) em amostras de rim. Por fim, realizou-se uma análise quantitativa destes compostos por espectrometria de absorção atómica com atomização electrotérmica (GFAAS), após a digestão das amostras pela tecnologia de microondas. O estudo histológico revelou necrose tubular aguda (ATN) nos animais expostos ao CCA e ao CrO3. Contudo, não se observaram quaisquer lesões significativas nos outros órgãos. Por esta razão, o estudo foi direccionado para o rim. A análise por citometria de fluxo (FCM) evidenciou a existência de diferenças significativas no ciclo celular dos grupos expostos ao As2O5 e ao CCA. Os ensaios bioquímicos revelaram uma tendência para a diminuição da actividade das enzimas CAT e GST, embora sem diferenças estatísticas significativas. A análise quantitativa demonstrou uma diminuição progressiva da acumulação de crómio e de arsénio nos rins. Por outro lado, observou-se que a distribuição de crómio e de arsénio era diferente para os diferentes grupos de tratamento. Por fim, o presente trabalho permite concluir que a nefrotoxicidade provocada pelo CCA nos ratinhos é muito mais acentuada do que a induzida pelo As2O5 e pelo CrO3, e alerta para o potencial tóxico do CCA para a saúde pública. ABSTRACT: Chromated copper arsenate (CCA) is a chemical wood preservative protecting timber from natural deterioration, containing chromium, copper and arsenic. Although on 2002, Environmental Protection Agency (EPA) had limited the use of CCA-treated wood, the environment contamination and the hazard to the public health will pursue due to the durability of this wood for 60 years. The main aim of the present work was the assessment of the acute toxicity of CCA, using mice as models. The development of a quantification methodology for chromium and arsenic in mice kidneys was another goal. In these studies, it was designed a set of experiments to investigate the effects caused by CCA, and the individual effects induced by arsenic pentoxide (As2O5) and chromium trioxide (CrO3) in thymus, liver, spleen, testis, epididymis and kidney. Sixteen groups of five animals each were considered in these studies, corresponding to different times of exposure. Treated groups received a single subcutaneous injection (0,3mL) of CCA, CrO3 and As2O5. In addition, control animals were administrated with the vehicle only. Following 14h, 24h, 48h and 96h animals were sacrificed, for organs removal. Afterwards, body and organs weights were also recorded. Subsequently, histology and histochemistry analysis was done. Furthermore, flow cytometry (FCM) approach was also considered for determination of cell cycle. Additionally, a set of preliminary enzyme assays was done to study the oxidative stress stimulated by these treatments. At last, the quantification of these compounds was also performed in kidney samples by graphite furnace atomic absorption spectrometry (GFAAS), after the digestion of the samples by microwave technology. The histology results, as confirmed by histochemistry, revealed acute tubular necrosis (ATN) induced by CCA and CrO3. Moreover, while FCM analysis revealed differences in cell cycle, enzyme assays showed a tendency to the decrease of the activities of CAT and GST. Finally, quantitative assays demonstrated a progressive decrease of the accumulation of CCA, arsenic and chromium during de exposure time, although no changes were observed within the other organs. For this reason, kidneys were carefully investigated. These results indicated that CCA-induced nephrotoxicity was more prominent than those caused by As2O5, and CrO3, which is an alert for its potential toxic effects on human health.

Abstract:

In this thesis, we introduce a novel model based on the idea of autoencoders. Different from a classic autoencoder which reconstructs its own inputs through a neural network, our model is closer to Kernel Canonical Correlation Analysis (KCCA) and reconstructs input data from another data set, where these two data sets should have some, perhaps non-linear, dependence. Our model extends traditional KCCA in a way that the non-linearity of the data is learned through optimizing a kernel function by a neural network. In one of the novelties of this thesis, we do not optimize our kernel based upon some prediction error metric, as is classical in autoencoders. Rather, we optimize our kernel to maximize the "coherence" of the underlying low-dimensional hidden layers. This idea makes our method faithful to the classic interpretation of linear Canonical Correlation Analysis (CCA). As far we are aware, our method, which we call a Kernel Coherence Encoder (KCE), is the only extent approach that uses the flexibility of a neural network while maintaining the theoretical properties of classic KCCA. In another one of the novelties of our approach, we leverage a modified version of classic coherence which is far more stable in the presence of high-dimensional data to address computational and robustness issues in the implementation of a coherence based deep learning KCCA.

Abstract:

The primary purpose of this treatise is to reexamine the South African labour dispute resolution bodies to see if they live up to the legislation’s promise of promoting social justice in conciliation, arbitration and con-arb processes concluded by them. The study defines social justice and examines this term in relation to employment law. The promotion of social justice was reaffirmed by the International Labour Organisation in its 1944 Conference which was later incorporated into its Constitution. The study briefly reviews the importance of this conference of the 10 May 1944 in relation to promoting social justice. The study also examines the social justice in the context of South African employment laws by briefly analyzing each South African labour legislation and the Constitution. This analysis is based on the provisions of legislation and considers if the respective provisions promote social justice as required by the International Labour Organisation’s Constitution and later by the South African Constitution. In analyzing the Constitution, and other legislation like the; Employment Equity Act (EEA), and Labour Relations Act (LRA), the treatise examines certain cases that were determined under the legislation from social justice perspective. The Labour Relations Act 66 of 1995 represents one of the major reforms of the labour relations system in South Africa. It is guided by the Constitution in terms of promoting social justice. The LRA established the dispute resolution bodies that are mandated by the legislation to resolve labour disputes. The study examines the systems and the processes employed by these bodies mainly the Commission for Conciliation; Mediation and Arbitration (CCMA) and the Bargaining Councils to determine if these systems are promoting social justice as required by the legislation. In conducting this analysis the study considers not only the processes adopted but also the manner in which the relevant dispute resolution bodies market their services; their strategies and operational plans; and accessibility and more. The study further investigates the challenges that these bodies are faced with that have a negative impact on their responsibility to promote social justice. These challenges faced by society range from unemployment, the level of literacy and the growing inequality within South African society. They constantly pose a challenge and require these bodies to consistently devise means and strategies to overcome them. A limited comparative study is undertaken in order to determine whether South Africa can learn anything from another country. There are several countries that may have been chosen to conduct this study but the study considered the fact that it needs to look at the country without the sub-Saharan Africa. The country that shares a history similar to South Africa due to the fact that the social challenges faced by the South African society might be similar to those faced by the country chosen. In this research Namibia was chosen as a suitable country to determine whether there is something to learn from it or not. In conclusion it is submitted that South African legislation pertaining to labour dispute resolution needs to constantly evolve in order to promote social justice challenges of the time.

Abstract:

L’étude des relations entre chrétiens et juifs, de la place de ces derniers dans la société catalane et, parfois, de leur statut légal a fait l’objet d’une historiographie abondante depuis le XIXe siècle. Nous avons choisi d’aborder ces questions à travers le droit processuel et la justice pour la période 1301- 1327, grâce à l’examen des sources normatives catalanes et de 800 documents de la pratique judiciaire, dont 655 sont inédits. Après avoir proposé une analyse de la hiérarchie des normes en vigueur, nous avons pu nuancer le postulat, largement admis, selon lequel les juifs, constituant les serfs du roi, relevaient nécessairement de sa compétence judiciaire exclusive. Par ailleurs, l’étude de notre corpus a révélé un traitement peu différencié entre les droits processuels des justiciables chrétiens et juifs, ces derniers semblant bénéficier d’un accès similaire à la justice malgré certains aménagements. En revanche, leur capacité à accéder à des fonctions judiciaires était restreinte, ce qui affectait indirectement l’équité de la justice à leur égard. Finalement, c’est au moment du jugement, à l’instant crucial de l’énoncé de la sentence, que la judéité du justiciable influait, les peines pouvant différer selon la religion de l’accusé et de la victime The study of the relationship between Christians and Jews, the place of Jews in Catalan society and their legal status has been the object of an abundant historiography since the nineteenth century. This thesis addresses these issues through the procedural law and justice for the period 1301-1327, through the review of the Catalan normative sources and 800 documents of judicial practice, 655 of which are new. After proposing an analysis of the hierarchy of norms, I have been able to question the assumption, widely accepted, that the Jews, constituting the king's serfs necessarily fall within the exclusive jurisdiction of the crown. Furthermore, the study of the corpus has revealed a poorly-differentiated treatment between procedural rights of Christian and Jewish litigants: Jews in general benefitted from similar access to justice despite some adjustments. However, their ability to access judicial power was restricted, which indirectly affected the fairness of justice towards them. Finally, it is at the time of judgment, in the crucial moment of the statement of the sentence, that the Jewishness of the defendant influenced the penalties which may differ depending on the religion of the accused and the victim

Abstract:

Thesis (MComm (Industrial Psychology))--University of Stellenbosch, 2010. ENGLISH ABSTRACT: One of the transformations that occurred in post-apartheid South Africa was the overhaul of labour legislation. The Labour Relations Act, 1995, the most pivotal product of the exercise, enacted the Commission for Conciliation, Mediation and Arbitration (CCMA) as a statutory labour dispute resolution institution. Given the failures of the previous dispute resolution system, the creators of the CCMA meant it to provide efficient, accessible and quality dispute resolution structured around conciliation and arbitration. The CCMA came into being in November 1996. The question that arises is: is the CCMA delivering efficient, accessible and quality dispute resolution? This research attempts to answer this question. The literature review indicates that, in terms of efficiency, the CCMA underperformed in the early years, from its inception to the year ended 2004. Improvements started trickling in after 2004. The literature review portrays a positive picture of accessibility: that the CCMA is accessible to its users. As for the quality of dispute resolution, the literature review paints a negative picture: that the CCMA does not provide a quality dispute resolution service. The researcher collected secondary data from the CCMA and primary data from parties to dispute resolution at the Cape Town Office of the CCMA, using a self-developed questionnaire. The data was analysed using Statistica version 9. The results show that the CCMA continues to grow and build on its previous efficiency successes: the CCMA concludes conciliations and arbitrations within the statutory time limits of 30 days and 60 days respectively. The results also show that the CCMA is accessible: the respondents found the process of referral and the actual processes of conciliation and arbitration informal. The results also show that the CCMA provides quality dispute resolution. All the respondents ranked the quality of conciliations and arbitrations positively. The results for efficiency and accessibility support the literature review. The results for quality of dispute resolution contradict the literature review. Based on these findings, insightful conclusions are drawn and recommendations are made, to both the CCMA and for future research. AFRIKAANSE OPSOMMING: Die hersiening van arbeidswetgewing was een van die transformasies wat plaasgevind het in post-apartheid Suid-Afrika. Die mees uitstaande produk van hierdie oefening, naamlik die nuwe Wet op Arbeidsverhoudinge, 1995, het die Kommissie vir Versoening, Bemiddeling en Arbitrasie (KVBA) daargestel as 'n instelling vir statutêre geskilbeslegting. Gesien teen die agtergrond van die mislukkings van die vorige geskilbeslegtingstelsel het die skeppers van die KVBA probeer om effektiewe, toeganklike en kwaliteit geskilbeslegting met betrekking tot versoenings en arbitrasies te skep. Die KVBA het in November 1996 tot stand gekom en funksioneer vir die afgelope 13 jaar. Die literatuurstudie toon aan dat, in terme van effektiwiteit, die KVBA onderpresteer het vanaf sy ontstaan tot en met 2004. Ná 2004 het verbeteringe drupsgewys ingetree. Die literatuurstudie skets 'n negatiewe beeld met verwysing na die gehalte van geskilbeslegting: die KVBA verskaf nie 'n geskilbeslegting diens van gehalte nie. Die navorsing het sekondêre data vanaf die KVBA en primêre data van die partye betrokke by geskilbeslegting in die Kaapstad-kantoor van die KVBA ingesamel deur van 'n selfontwikkelde vraelys gebruik te maak. Die resultate toon dat die KVBA voortgaan om te groei en te bou op vorige suksesse ten opsigte van effektiwiteit: die KVBA handel versoenings en arbitrasies binne die statutêre tydsbepalings van 30 en 60 dae onderskeidelik af. Die resultate toon ook dat die KVBA toeganklik is: die respondente het die proses van arbitrasie as informeel ervaar. Die resultate toon ook dat die KVBA 'n kwaliteit geskilbeslegtingsfunksie verskaf. Alle respondente het die gehalte van versoenings positief beoordeel. Die resultate ten opsigte van effektiwiteit en toeganklikheid ondersteun die literatuurstudie. Die resultate ten opsigte van die gehalte van die geskilbeslegtingsfunksie is strydig met die literatuurstudie. Voortvloeiend uit hierdie bevindinge, word tot insiggewende gevolgtrekkings gekom en aanbevelings word gemaak vir gebruik deur die KVBA, asook vir toekomstige navorsing.
