The challenge of MNCs and development: oil extraction, CSR, Nigeria and corruption

Globalisation has led to a shift in world order with the rise of the corporate non-state actor. This rise has led to an assumption that Multi-National Corporations (MNCs) must assume responsibilities beyond profit maximisation for shareholders. With the rise of the MNC as a corporate non-state actor there have been discussions around the role of business with regard to human rights. <br/><br/>This article looks at the case of oil extraction in Nigeria. Focussing on the historical dependency of Nigeria and the evolution of the state into a resource-dependent country, it looks at the limitations of existing human rights obligations as they relate to business. This article proposes that corporate social responsibility (CSR) policies of MNCs can act as a preliminary stage in the quest for wider human rights protections. It is in motivating MNCs to design and implement effective CSR policies in dependent states like Nigeria, that the challenge lies. <br/>

Piezoelectricity and ferroelectricity in amino acid glycine

Bioorganic ferroelectrics and piezoelectrics are becoming increasingly important in view of their intrinsic compatibility with biological environment and biofunctionality combined with strong piezoelectric effect and switchable polarization at room temperature. Here we study piezoelectricity and ferroelectricity in the smallest amino acid glycine, representing a broad class of non-centrosymmetric amino acids. Glycine is one of the basic and important elements in biology, as it serves as a building block for proteins. Three polymorphic forms with different physical properties are possible in glycine (α, β and γ), Of special interest for various applications are non-centrosymmetric polymorphs: β-glycine and γ-glycine. The most useful β-polymorph being ferroelectric took much less attention than the other due to its instability under ambient conditions. In this work, we could grow stable microcrystals of β-glycine by the evaporation of aqueous solution on a (111)Pt/Ti/SiO2/Si substrate as a template. The effects of the solution concentration and Pt-assisted nucleation on the crystal growth and phase evolution were characterized by X-ray diffraction analysis and Raman spectroscopy. In addition, spin-coating technique was used for the fabrication of highly aligned nano-islands of β-glycine with regular orientation of the crystallographic axes relative the underlying substrate (Pt). Further we study both as-grown and tip-induced domain structures and polarization switching in the β-glycine molecular systems by Piezoresponse Force Microscopy (PFM) and compare the results with molecular modeling and computer simulations. We show that β-glycine is indeed a room-temperature ferroelectric and polarization can be switched by applying a bias to non-polar cuts via a conducting tip of atomic force microscope (AFM). Dynamics of these in-plane domains is studied as a function of applied voltage and pulse duration. The domain shape is dictated by both internal and external polarization screening mediated by defects and topographic features. Thermodynamic theory is applied to explain the domain propagation induced by the AFM tip. Our findings suggest that β-glycine is a uniaxial ferroelectric with the properties controlled by the charged domain walls which in turn can be manipulated by external bias. Besides, nonlinear optical properties of β-glycine were investigated by a second harmonic generation (SHG) method. SHG method confirmed that the 2-fold symmetry is preserved in as-grown crystals, thus reflecting the expected P21 symmetry of the β-phase. Spontaneous polarization direction is found to be parallel to the monoclinic [010] axis and directed along the crystal length. These data are confirmed by computational molecular modeling. Optical measurements revealed also relatively high values of the nonlinear optical susceptibility (50% greater than in the z-cut quartz). The potential of using stable β-glycine crystals in various applications are discussed in this work.

Carers and Co-Production: Enabling Expertise through Experience?

Purpose To provide a brief overview of the literature to date which has focussed on co-production within mental healthcare in the UK, including service user and carer involvement and collaboration. Design The paper presents key outcomes from studies which have explicitly attempted to introduce co-produced care in addition to specific tools designed to encourage co-production within mental health services. The paper debates the cultural and ideological shift required for staff, service users and family members to undertake co-produced care and outlines challenges ahead with respect to service redesign and new roles in practice. Findings Informal carers (family and friends) are recognised as a fundamental resource for mental health service provision, as well as a rich source of expertise through experience, yet their views are rarely solicited by mental health professionals or taken into account during decision-making. This issue is considered alongside new policy recommendations which advocate the development of co-produced services and care. Research Limitations Despite the launch of a number of initiatives designed to build on peer experience and support, there has been a lack of attention on the differing dynamic which remains evident between healthcare professionals and people using mental health services. Co-production sheds a light on the blurring of roles, trust and shared endeavour (Slay and Stephens, 2013) but, despite an increase in peer recovery workers across England, there has been little research or service development designed to focus explicitly on this particular dynamic. Practical Implications Despite these challenges, coproduction in mental healthcare represents a real opportunity for the skills and experience of family members to be taken into account and could provide a mechanism to achieve the ‘triangle of care’ with input, recognition and respect given to all (service users, carers, professionals) whose lives are touched by mental distress. However, lack of attention in relation to carer perspectives, expertise and potential involvement could undermine the potential for coproduction to act as a vehicle to encourage person-centred care which accounts for social in addition to clinical factors. Social Implications The families of people with severe and enduring mental illness (SMI) assume a major responsibility for the provision of care and support to their relatives over extended time periods (Rose et al, 2004). Involving carers in discussions about care planning could help to provide a wider picture about the impact of mental health difficulties, beyond symptom reduction. The ‘co-production of care’ reflects a desire to work meaningfully and fully with service users and carers. However, to date, little work has been undertaken in order to coproduce services through the ‘triangle of care’ with carers bringing their own skills, resources and expertise. Originality/Value This paper debates the current involvement of carers across mental healthcare and debates whether co-production could be a vehicle to utilise carer expertise, enhance quality and satisfaction with mental healthcare. The critique of current work highlights the danger of increasing expectations on service providers to undertake work aligned to key initiatives (shared decision-making, person-centred care, co-production), that have common underpinning principles but, in the absence of practical guidance, could be addressed in isolation rather than as an integrated approach within a ‘triangle of care’.

Russia and the Arab Spring: supporting the counter-revolution

Russia’s response to the Arab Spring ranged from apprehension to deep anxiety and diverged significantly from the US and the EU responses. While initially welcoming the popular demands for political reform in North Africa, the Russian reaction rapidly became more critical as a result of Western military intervention into Libya and the threat of the spread of Islamist extremism. It was these twin fears which prompted the Russian leadership to adopt an uncompromizing stance towards Syria. While geopolitical factors certainly played a role in driving Russian strategy, domestic political factors were also more significant. As the Russian leadership felt internally threatened by the growing opposition within the country, conflict in the Middle East highlighted the perceived flaws of the imposition of Western liberal democracy and the virtues of Russia’s own model of state-managed political order. There was, as such, a significant ideational and ideological dimension to the Russian response to the Arab Spring.

Anatomy of the portuguese stock market risk and return in the 1977-2012 period

This paper analyses the Portuguese stock market since it reopened in 1977, with a special focus on the evolution of the statistic and stochastic characteristics of the market return throughout this 36 year period. The market return for the period of time between 1977 and 2012 (September 28th) is estimated and then compared with the return that would have been achieved with Government bonds and treasury bills, which allows us to confirm that the hierarchy of return / risk across the different financial instruments is verified. The market risk premium for this 36 year period is also estimated and a comparison with other markets is performed, suggesting that the Portuguese market’s risk has not been compensated by an adequate return. The study also examines the evolution of the Portuguese market’s volatility in the 1977-2012 period and compares it with other markets, showing the existence of extremely high peaks during the first 11 years, but indicating a downwards trend throughout the whole period under analysis. Finally, the correlation between market returns for Portugal and for other countries and the degree of integration are estimated and their evolution throughout time is assessed, leading to the conclusion that the performance of the Portuguese stock market has become increasingly correlated with major European markets – correlation with some markets close to 0.70 from 2000 onwards-, but that country-specific risk factors are still relevant.

The waning of the two giants: the electoral decline of the Italian Christian Democratic Party and the Italian Communist Party

Italy is currently experiencing profound political change. One aspect of this change involves the decline in electoral support for the Italian Christian Democratic Party (DC) and the Italian Communist Party (PCI), now the Democratic Party of the Left (PDS). Signs of the electoral decline of both parties began to appear in the late 1970s and early 1980s and accelerated in the late 1980s and early 1990s. The pr imar y purpos e of th is thes is is to expla i n the electoral decline of the DC and PCI/PDS in the last decade. The central question being addressed in this thesis is the following: What factors contributed to the decline in electoral support for the DC and PCI? In addition, the thesis attempts to better comprehend the change in magni tude and direction of the Italian party system. The thesis examines the central question within an analytical framework that consists of models explaining electoral change in advanced industrial democracies and in Italy. A review of the literature on electoral change in Italy reveals three basic models: structural (socioeconomic and demographic factors), subcultural (the decline of the Catholic and Communist subcultures), and pol i tical (factors such as party strategy, and the crisis and collapse of communism in iv Eastern Europe and the former soviet Union and the end to the Cold War). Significant structural changes have occurred in Italy, but they do not invariably hurt or benefit either party. The Catholic and Communist subcultures have declined in size and strength, but only gradually. More importantly, the study discovers that the decline of communism and party strategy adversely affected the electoral performances of the DC and PC!. The basic conclusion is that political factors primarily and directly contributed to the decline in electoral support for both parties, while societal factors (structural and subcultural changes) played a secondary and indirect role. While societal factors do not contribute directly to the decline in electoral support for both parties, they do provide the context within which both parties operated. In addition, the Italian party system is becoming more fragmented and traditional political parties are losing electoral support to new political movements, such as the Lega Nord (LN-Northern League) and the Rete (Network). The growing importance of the North-South and centre-periphery cleavages suggests that the Italian party system, which is traditionally based on religious and ideological cleavages, may be changing.

Evolution of architectural floor plans

Layout planning is a process of sizing and placing rooms (e.g. in a house) while a t t empt ing to optimize various criteria. Often the r e are conflicting c r i t e r i a such as construction cost, minimizing the distance between r e l a t ed activities, and meeting the area requirements for these activities. The process of layout planning ha s mostly been done by hand, wi th a handful of a t t empt s to automa t e the process. Thi s thesis explores some of these pa s t a t t empt s and describes several new techniques for automa t ing the layout planning process using evolutionary computation. These techniques a r e inspired by the existing methods, while adding some of the i r own innovations. Additional experimenLs are done to t e s t the possibility of allowing polygonal exteriors wi th rectilinear interior walls. Several multi-objective approaches are used to evaluate and compare fitness. The evolutionary r epr e s ent a t ion and requirements specification used provide great flexibility in problem scope and depth and is worthy of considering in future layout and design a t t empt s . The system outlined in thi s thesis is capable of evolving a variety of floor plans conforming to functional and geometric specifications. Many of the resulting plans look reasonable even when compared to a professional floor plan. Additionally polygonal and multi-floor buildings were also generated.

La razón de los tontos : protagonismo de los grupos subalternos en la formación de una conciencia de unidad nacional en Latinoamérica

Cette thèse est une étude des groupes subalternes en Amérique Latine qui se concentre principalement sur l’examen de la production littéraire que ces groupes ont inspirée mais aussi sur les tensions sociales, idéologiques et culturelles dérivées de leur présence au sein d’une nation. Ces groupes qu’on va identifier méthodologiquement comme étant des Groupes Subalternes sont apparus dans le panorama littéraire et politique d’une manière peu habituelle, plus par leur négativité en relation au projet moderne d’institutionnalisation positiviste que par les particularités de leur culture. Néanmoins, ils sont devenus, par la suite, le symbole iconographique de l’identité nationale de leurs pays respectifs. Ces groupes qui, par définition, étaient destinés à sombrer dans l’oubli historique sont devenus plus tard les protagonistes des «guiding fictions» de la formation d’une conscience d’unité nationale. Les textes qui seront examinés au cours de cette recherche sont ceux qui montrent de manière paradigmatique la réalité et les modes d’existence de ces populations qui ont été caractérisées par leur négativité par rapport aux normes de la pensée hégémonique moderne dans l’espace socio-culturelle et -politique de l’Amérique latine. Ces textes nous montrent une déviation dans l’évolution historico-discursive de la vision que les artisans idéologiques des États-nation naissants ont voulu imposer sur ces groupes vers la fin du XIX e. Dans cette étude, on analysera deux exemples paradigmatiques : celui de la communauté de Canudos au Brésil, à travers le texte « Os Sertões » d’Euclides Da Cunha, et celui des gauchos de l’Argentine, à travers l’examen du texte « El Martin Fierro » de Jose Hernandez. Dans la première partie de cette thèse on dessine, à grands traits, les repères historiques et socio-politiques des idéologies qui ont abouti au processus de modernisation de l’Amérique latine. On propose, au même temps, quelques concepts critiques vis-à-vis de l’analyse des groupes subalternes. Dans les chapitres suivants, on procède à une lecture attentive des textes mentionnés plus haut, tout en considérant, à la fois, la nécessité de cette analyse, la difficulté des problèmes et la nature de notre propos. On explique aussi la place qu’occupent les groupes subalternes dans la représentation littéraire de leur pays d’origine et l’impact qu’ils ont eu dans la formation de l’imaginaire national. En réfléchissant sur les données engendrées lors de l’analyse, la conclusion de la thèse aborde les conséquences épistémologique et idéologique provoquées par le régime discursif de l’État-nation latino-américain.

The institutional choices of politicians : how and why legislators shape Lower Chambers

Cette thèse s’intéresse aux choix institutionnels des législateurs. Elle propose une analyse diachronique et comparative du développement des Chambre Nationale des Députés argentines et chiliennes des années 1940 aux années 2000. Inspiré de la théorie du Cartel (Cox et McCubbins, 1993), ce travail se concentre sur le rôle des partis politiques dans ce développement institutionnel. Il montre qu’en dépit de leurs différences, les partis uniques, coalitions, forces majoritaires ou minoritaires qui ont dirigé ces chambres ont adopté un large éventail de règles et de normes organisationnelles qui les avantagent. Ils se sont, en un mot, comportés comme des coalitions procédurales. L’analyse des modifications des règles de fonctionnement de ces chambres et de leurs systèmes de direction et de commissions montre que les partis et coalitions au pouvoir ont, pendant cette période, renforcé leur pouvoir, contrôlé l’agenda législatif, structuré les systèmes de commission et adopté des règles qui leur ont profité. Les résultats obtenus suggèrent en particulier que les coalitions qui ont dirigé la chambre Chilienne ont installé certains de leurs membres à plusieurs postes comme les présidences d’assemblée et de commissions. Ils montrent l’existence d’un pouvoir de véto sur l’agenda législative plus importante au Chili qu’en Argentine. L’étude du cas argentin montre que les partis au pouvoir ont, en particulier depuis les années 1960, conservé le contrôle de la chambre, non seulement en modifiant les règles et les structures du système de commissions, mais également en créant et distribuant à l’opposition des postes permanents mais sans réel pouvoir. Cette analyse confirme également les résultats obtenus par de récentes études concernant ce champ de recherche, notamment le professionnalisme du système de commission chilien et le caractère amateur des législateurs argentins. A l’inverse, elle met à jour des différences, négligées jusqu’alors, entre l’Argentine et le Chili concernant le contrôle de l’agenda législatif. Cette thèse est divisée en sept chapitres. Le premier introduit le sujet, l’hypothèse générale et les questions posées par la thèse, en expliquant également pourquoi les choix institutionnels des législateurs importent. Le chapitre II présente la théorie et la méthodologie. Il propose une définition du développement institutionnel et explicite les prédictions et critères permettant de tester l’hypothèse générale. Les chapitre III et IV, qui concernent respectivement l’Argentine et le Chili, décrivent le système politique de chaque pays et l’organisation des chambres durant la période étudiée. Les chapitre IV et VI, respectivement pour l’Argentine et le Chili, analysent les réformes des règles régissant les chambres, l’évolution de l’autorité qui les dirige et celle du système de commission. Ces chapitres se concluent par un résumé des différents schémas mis en évidence et une évaluation préliminaire de l’hypothèse générale. En conclusion, le chapitre VII résume les découvertes, donne un verdict global sur la fécondité de la théorie et suggère de nouvelles pistes de recherche.

Le rôle du paysage dans l’évolution d’une ville industrielle : la géographie structurale de Drummondville

Dans cette recherche, nous tentons de démontrer le rôle du paysage dans la structuration des villes industrielles, afin de justifier sa considération dans les outils de planification. Pour atteindre cet objectif, nous nous penchons sur une ville manufacturière du Centre-du-Québec : Drummondville. Nous utilisons une méthodologie en trois étapes. Nous réalisons en premier lieu un historique puis une analyse paysagère. Pour dépasser la simple description des paysages et de l’évolution de la forme urbaine, nous interprétons ensuite ces résultats en fonction des domaines de cohérence de la géographie structurale. Selon cette théorie, Drummondville constitue un domaine de cohabitation. Le rôle du paysage dans le développement et la structuration du territoire varie en fonction des sensibilités dominantes. Il est donc plus important lors des périodes qui valorisent les formes esthétiques et culturelles et moins structurant lorsque les valeurs dominantes favorisent les formes rationnelles. Dans les domaines de cohabitation où les forces industrielles sont plus constantes, des aménagements utilitaires sont parfois réalisés sur des sites paysagers. En raison de leur plus faible valorisation, les paysages y sont plus souvent menacés. En ce sens, il importe d’autant plus de les considérer dans les documents de planification.
