European Union Non-Discrimination Law: Comparative Perspectives on Multidimensional Equality Law

EU equality law is multidimensional in being based on different rationales and concepts. Consequently, the concept of discrimination has become fragmented, with different instruments envisaging different scopes of protection. This raises questions as to the ability of EU law to address the situation of persons excluded on a number of grounds. This edited collection addresses the increasing complexity of European Equality Law from jurisprudential, sociological and political science perspectives. Internationally renowned researchers from Scandinavian, Continental and Central European countries and Britain analyse consequences of multiplying discrimination grounds within EU equality law, considering its multidimensionality and intersectionality. The contributors to the volume theorise the move from formal to substantive equality law and its interrelation to new forms of governance, demonstrating the specific combination of non-discrimination law with welfare state models which reveal the global implications of the European Union. The book will be of interest to academics and policy makers all over the world, in particular to those researching and studying law, political sciences and sociology with an interest in human rights, non discrimination law, contract and employment law or European studies.

Non-Markovian qubit dynamics in a circuit-QED setup

We consider a circuit-QED setup that allows the induction and control of non-Markovian dynamics of a qubit. Non-Markovianity is enforced over the qubit by means of its direct coupling to a bosonic mode which is controllably coupled to another qubit-mode system. We show that this configuration can be achieved in a circuit-QED setup consisting of two initially independent superconducting circuits, each formed by one charge qubit and one transmission-line resonator, which are put in interaction by coupling the resonators to a current-biased Josephson junction. We solve this problem exactly and then proceed with a thorough investigation of the emergent non-Markovianity in the dynamics of the qubits. Our study might serve the context for the first experimental assessment of non-Markovianity in a multielement solid-state device.

An integrated approach for real-time model-based state-of-charge estimation of lithium-ion batteries

Lithium-ion batteries have been widely adopted in electric vehicles (EVs), and accurate state of charge (SOC) estimation is of paramount importance for the EV battery management system. Though a number of methods have been proposed, the SOC estimation for Lithium-ion batteries, such as LiFePo4 battery, however, faces two key challenges: the flat open circuit voltage (OCV) vs SOC relationship for some SOC ranges and the hysteresis effect. To address these problems, an integrated approach for real-time model-based SOC estimation of Lithium-ion batteries is proposed in this paper. Firstly, an auto-regression model is adopted to reproduce the battery terminal behaviour, combined with a non-linear complementary model to capture the hysteresis effect. The model parameters, including linear parameters and non-linear parameters, are optimized off-line using a hybrid optimization method that combines a meta-heuristic method (i.e., the teaching learning based optimization method) and the least square method. Secondly, using the trained model, two real-time model-based SOC estimation methods are presented, one based on the real-time battery OCV regression model achieved through weighted recursive least square method, and the other based on the state estimation using the extended Kalman filter method (EKF). To tackle the problem caused by the flat OCV-vs-SOC segments when the OCV-based SOC estimation method is adopted, a method combining the coulombic counting and the OCV-based method is proposed. Finally, modelling results and SOC estimation results are presented and analysed using the data collected from LiFePo4 battery cell. The results confirmed the effectiveness of the proposed approach, in particular the joint-EKF method.

Non-domination, non-alienation and social equality: towards a republican understanding of equality

The republican idea of non-domination stresses the importance of certain social relationships for a person’s freedom, showing that freedom is a social-relational state. While the idea of freedom as non-domination receives a lot of attention in the literature, republican theorists say surprisingly little about equality. Therefore, the aim of this paper is to carve out the contours of a republican conception of equality.. In so doing, I will argue that republican accounts of equality share a significant normative overlap with the idea of social equality. However, closer analysis of Philip Pettit’s account of ‘expressive egalitarianism’ (which Pettit sees as inherently connected to non-domination) and recent theories of social equality shows that republican non-domination – in contrast to what Pettit seems to claim – is not sufficient for securing (republican) social equality. In order to secure social equality for all, republicans would have to go beyond non-domination.

Ultrafast Non-Radiative Decay of Gas-Phase Nucleosides

The ultrafast photo-physical properties of DNA are crucial in providing a stable basis for life. Although the DNA bases efficiently absorb ultraviolet (UV) radiation, this energy can be dissipated to the surrounding environment by the rapid conversion of electronic energy to vibrational energy within about a picosecond. The intrinsic nature of this internal conversion process has previously been demonstrated through gas phase experiments on the bases, supported by theoretical calculations. De-excitation rates appear to be accelerated when individual bases are hydrogen bonded to solvent molecules or their complementary Watson-Crick pair. In this paper, the first gas-phase measurements of electronic relaxation in DNA nucleosides following UV excitation are reported. Using a pump-probe ionization scheme, the lifetimes for internal conversion to the ground state following excitation at 267 nm are found to be reduced by around a factor of two for adenosine, cytidine and thymidine compared with the isolated bases. These results are discussed in terms of a recent proposition that a charge transfer state provides an additional internal conversion pathway mediated by proton transfer through a sugar to base hydrogen bond.

Survival and behaviour of the earthworms Lumbricus rubellus and Dendrodrilus rubidus from arsenate-contaminated and non-contaminated sites

Two arsenic- and heavy metal-contaminated mine-spoil sites, at Carrock Fell, Cumbria and Devon Great Consols Mine, Devon, were found to support populations of the earthworms Lumbricus rubellus Hoffmeister and Dendrodrilus rubidus (Savigny). L. rubellus and D. rubidus collected from the Devon site and an uncontaminated site were kept for 28 days in uncontaminated soil and in soil containing sodium arsenate (494 mg As kg^-1). The state of the specimens was recorded every 7 days using a semi-quantitative assessment of earthworm health (condition index, C. I.). The C. I. remained high for all specimens except those of L. rubellus and D. rubidus from uncontaminated sites, which displayed 60 and 10% mortality, respectively. L. rubellus collected from the Carrock Fell site, and L. rubellus and D. rubidus from an uncontaminated site, burrowed as rapidly into soil containing up to 1235 mg As kg^-1 in the form of sodium arsenate as into uncontaminated soil when placed on the soil surface. When earthworms were allowed a choice between uncontaminated soil and soil contaminated with sodium arsenate in concentrations of up to 1235 mg As kg^-1, the threshold concentration for avoidance of contaminated soil was lower for L. rubellus and D. rubidus from uncontaminated soil than for specimens from contaminated soil. There was no significant effect of pH on soil discrimination. The LC₅₀ concentration of As for L. rubellus from Devon Great Consols was significantly higher (P < 0.001) than for L. rubellus from the uncontaminated site: 1510 and 96 mg As kg^-1, respectively. © 2001 Elsevier Science Ltd.

Civilianizing Civil Conflict: Civilian Defense Militias and the Logic of Violence in Intra-State Conflict

This article examines how civilian defense militias shape violence during civil war. We define civilian defense forces as a sedentary and defensive form of pro-government militia that incumbents often use to harness the participation of civilians during a counterinsurgency campaign. We argue that civilian defense forces reduce the problem of insurgent identification. This leads to a reduction in state violence against civilians. However, we also claim that these actors undermine civilian support for insurgents, which leads to an increase in rebel violence against civilians and overall intensification of conflict. A statistical analysis of government and rebel violence against civilians from 1981 to 2005, and a qualitative assessment of a civilian defense force operating in Iraq from 2005 to 2009, offer strong support for our theoretical claims. These findings provide further insight into pro-government militias and their effects on violence. They also have wider ethical implications for the use of civilian collaborators during civil war.

Non-parametric bill of quantities estimation of concrete road bridges' superstructure: an artificial neural networks approach

Bridge construction responds to the need for environmentally friendly design of motorways and facilitates the passage through sensitive natural areas and the bypassing of urban areas. However, according to numerous research studies, bridge construction presents substantial budget overruns. Therefore, it is necessary early in the planning process for the decision makers to have reliable estimates of the final cost based on previously constructed projects. At the same time, the current European financial crisis reduces the available capital for investments and financial institutions are even less willing to finance transportation infrastructure. Consequently, it is even more necessary today to estimate the budget of high-cost construction projects -such as road bridges- with reasonable accuracy, in order for the state funds to be invested with lower risk and the projects to be designed with the highest possible efficiency. In this paper, a Bill-of-Quantities (BoQ) estimation tool for road bridges is developed in order to support the decisions made at the preliminary planning and design stages of highways. Specifically, a Feed-Forward Artificial Neural Network (ANN) with a hidden layer of 10 neurons is trained to predict the superstructure material quantities (concrete, pre-stressed steel and reinforcing steel) using the width of the deck, the adjusted length of span or cantilever and the type of the bridge as input variables. The training dataset includes actual data from 68 recently constructed concrete motorway bridges in Greece. According to the relevant metrics, the developed model captures very well the complex interrelations in the dataset and demonstrates strong generalisation capability. Furthermore, it outperforms the linear regression models developed for the same dataset. Therefore, the proposed cost estimation model stands as a useful and reliable tool for the construction industry as it enables planners to reach informed decisions for technical and economic planning of concrete bridge projects from their early implementation stages.

Improving the robustness of the iterative solver in state-space modelling of guitar distortion circuitry

Iterative solvers are required for the discrete-time simulation of nonlinear behaviour in analogue distortion circuits. Unfortunately,these methods are often computationally too expensive for realtime simulation. Two methods are presented which attempt to reduce the expense of iterative solvers. This is achieved by applying information that is derived from the specific form of the non linearity.The approach is first explained through the modelling of an asymmetrical diode clipper, and further exemplified by application to the Dallas Rangemaster Treble Booster guitar pedal, which provides an initial perspective of the performance on systems with multiple nonlinearities.

A Changing UK in a Changing Europe: The UK State between European Union and Devolution

Two issues currently dominate the UK's constitutional landscape: the UK's membership of the European Union (EU) on the one hand; and the unsettled constitutional settlements between the UK and the devolved administrations of Scotland, Wales and Northern Ireland on the other. This article considers these two issues in concert. It stresses the distinct relationships between the EU and the devolved territories within the UK—concerning both devolved and non-devolved policy areas—highlighting the salience of a devolved perspective in any consideration of UK–EU relations. Despite its importance, sensitivity to this has been lacking. The article explores the implications of a ‘Leave’ or ‘Remain’ outcome on the future of the internal territorial dynamics within the UK. While there are too many unknowns to be certain of anything, that there will be knock-on effects is, however, beyond doubt.

Study of oxidation and non-enzymatic glycosylation posttranslational modifications using a proteomic approach

A glicosilação não-enzimática e o stress oxidativo representam dois processos importantes visto desempenharem um papel importante no que respeita às complicações de vários processos patofisiológicos. No presente, a associação entre a glicosilação não-enzimática e a oxidação de proteínas é reconhecida como sendo um dos principais responsáveis pela acumulação de proteínas não-funcionais que, por sua vez, promove uma contínua sensibilização para um aumento do stress oxidativo ao nível celular. Embora esteja disponível bastante informação no que respeita aos dois processos e suas consequências ao nível estrutural e funcional, permanecem questões por esclarecer acerca do que se desenvolve ao nível molecular. Com o objectivo de contribuir para uma melhor compreensão da relação entre a glicosilação não-enzimática e a oxidação, proteínas modelo (albumina, insulina e histonas H2B e H1) foram submetidas a sistemas in vitro de glicosilação não-enzimática e oxidação em condições controladas e durante um período de tempo específico. A identificação dos locais de glicosilação e oxidação foi realizada através de uma abordagem proteómica, na qual após digestão enzimática se procedeu à análise por cromatografia líquida acoplada a espectrometria de massa tandem (MALDI-TOF/TOF). Esta abordagem permitiu a obtenção de elevadas taxas de cobertura das sequências proteicas, permitindo a identificação dos locais preferenciais de glicosilação e oxidação nas diferentes proteínas estudadas. Como esperado, os resíduos de lisina foram os preferencialmente glicosilados. No que respeita à oxidação, além das modificações envolvendo hidroxilações e adições de oxigénio, foram identificadas deamidações, carbamilações e conversões oxidativas específicas de vários aminoácidos. No geral, os resíduos mais afectados pela oxidação foram os resíduos de cisteína, metionina, triptofano, tirosina, prolina, lisina e fenilalanina. Ao longo do período de tempo estudado, os resultados indicaram que a oxidação teve início em zonas expostas da proteína e/ou localizadas na vizinhança de resíduos de cisteína e metionina, ao invés de exibir um comportamente aleatório, ocorrendo de uma forma nãolinear por sua vez dependente da estabilidade conformacional da proteína. O estudo ao longo do tempo mostrou igualmente que, no caso das proteínas préglicosiladas, a oxidação das mesmas ocorreu de forma mais rápida e acentuada, sugerindo que as alterações estruturais induzidas pela glicosilação promovem um estado pro-oxidativo. No caso das proteínas pré-glicosiladas e oxidadas, foi identificado um maior número de modificações oxidativas assim como de resíduos modificados na vizinhança de resíduos glicosilados. Com esta abordagem é realizada uma importante contribuição na investigação das consequências do dano ‘glico-oxidativo’ em proteínas ao nível molecular através da combinação da espectrometria de massa e da bioinformática.

A Agenda 21 local e o desenvolvimento sustentável em Portugal : que perspetivas?

Assumindo a sociedade atual o paradigma do desenvolvimento sustentável como modelo capaz de garantir uma gestão equilibrada dos recursos atuais que não comprometa o futuro das futuras gerações, é fundamental compreender o instrumento da Agenda 21 Local (A21L), ferramenta saída da Conferência do Rio, em 1992, que se apresenta como uma resposta internacional aos objetivos da sustentabilidade. Ao constituir-se como país signatário da Declaração do Rio, Portugal assumiu o compromisso de cooperar internacionalmente para a aplicação deste instrumento, no esforço comum de unir a proteção do ambiente com o desenvolvimento económico e social. Verifica-se que a resposta de Portugal, em matéria de A21L, foi pouco conseguida, marcada por um arranque ténue, desconcertado e disperso a que acresce o caráter dúbio que caracterizou a natureza dos primeiros processos e que, no quadro internacional, atira Portugal para o grupo de países europeus que mais tardiamente conseguiram responder ao apelo da comunidade internacional no que se refere à implementação de A21L. Neste âmbito, esta dissertação visa aprofundar o conhecimento cientifico sobre este instrumento no quadro das experiências de Agenda 21 Local implementadas no território português. O trabalho procurou examinar os objetivos, características e resultados dos processos de Agenda, dando atenção aos elementos individuais que marcaram cada um e, igualmente, avaliando as repercussões que estes tiveram no todo nacional. O estudo incidiu na dinâmica espaciotemporal das Agendas21L, no território nacional, e na análise integrativa de indicadores físicos, sociais e económicos que permitiram compreender as especificidades e os contrastes verificados nos processos implementados e desenvolvidos. Na investigação não foram, igualmente, negligenciadas questões históricas, políticas e culturais, sabendose da importância que estes vários domínios configuram no caso português. O trabalho contou com uma investigação assente na seguinte metodologia: i) Revisão da literatura e recolha de dados bibliográficos sobre a temática da Agenda 21 Local; ii) Levantamento de informação, através de um inquérito por questionário, dirigido a todas as localidades do País, onde decorrem Agendas 21 Local, a fim de complementar informação já processada; iii) Pesquisa direta de dados no terreno que envolveu a utilização de procedimentos de teor quantitativo (inquérito por questionário) e de teor qualitativo (entrevistas), relativamente ao caso de estudo (Agenda 21 Local de Mindelo); iv) Tratamento e análise dos resultados obtidos através da confrontação da perspetiva teórica com a prática com a consequente elaboração de conclusões fundamentadas pela confrontação dos dados com as hipóteses. Para além de se tratar do caso pioneiro de A21L com início no poder mais próximo do cidadão (respeitando um dos princípios inerentes a este instrumento – o princípio da subsidiariedade), afirmou-se, igualmente, como um caso de referência em matéria de coesão e mobilização dos cidadãos locais para os problemas locais existentes. Os resultados empíricos da investigação identificam uma série de dificuldades que condicionaram o arranque e progresso das A21L. Desde logo, a inabilidade dos poderes políticos locais em trabalharem com um modelo que rompe com as típicas e tradicionais formas pré-concebidas de fazer política, isto é, com as práticas instituídas dos políticos fazerem “política” para os cidadãos e não “com” os cidadãos. O próprio desconhecimento do poder político local quanto à natureza de um processo de A21L que evidenciou inaptidão, impreparação e até embaraço para lidar com este instrumento, resultando na necessidade, na grande maioria dos processos desenvolvidos, de serem acompanhados por entidades externas que cooperaram na sua dinamização. Acresce que a nova dinâmica, subjacente à A21L, que desafia os governos locais a mobilizar a participação generalizada dos cidadãos e apela à participação de novos atores (associações, grupos de interesse, ONG e atores sociais, em geral) para a definição de estratégias de desenvolvimento local, não é totalmente aceite pelos vários poderes locais que, não raras vezes, menosprezam a importância dos cidadãos nos momentos de tomada de decisão. A falta de empenho do governo central, em matéria de sustentabilidade, que negligenciou, numa primeira etapa, a figura do poder central na assessoria às entidades locais cerceou o país da existência de uma campanha nacional para a afirmação deste instrumento. A falta/insuficiência de recursos financeiros como resultante da ausência de apoios estatais e a dificuldade na obtenção de fundos da União Europeia configurou-se como um entrave à promoção dos processos ficando as entidades locais e regionais incapazes de ultrapassar a falta de meios imprescindíveis para o desenvolvimento da A21L. O próprio desconhecimento generalizado dos cidadãos sobre a A21L afigura-se como um estigma ao sucesso de qualquer processo com as caraterísticas de um instrumento A21L visto que a participação dos cidadãos é condição sine qua non para a sua operacionalização. Neste quadro, e olhando o futuro, urge a necessidade das autoridades locais criarem modelos de autofinanciamento capazes de garantir a criação, funcionamento e manutenção de infraestruturas económicas e sociais subjacentes aos programas de A21L, assim como o dever do poder político em reforçar a importância da função da informação e da mobilização dos cidadãos em prole do desenvolvimento sustentável, ações indispensáveis para a execução das políticas inerentes à A21L.

Electrical characterization of metal-oxide-polymer devices for non-volatile memory applications

The objective of this thesis is to study the properties of resistive switching effect based on bistable resistive memory which is fabricated in the form of Al2O3/polymer diodes and to contribute to the elucidation of resistive switching mechanisms. Resistive memories were characterized using a variety of electrical techniques, including current-voltage measurements, small-signal impedance, and electrical noise based techniques. All the measurements were carried out over a large temperature range. Fast voltage ramps were used to elucidate the dynamic response of the memory to rapid varying electric fields. The temperature dependence of the current provided insight into the role of trapped charges in resistive switching. The analysis of fast current fluctuations using electric noise techniques contributed to the elucidation of the kinetics involved in filament formation/rupture, the filament size and correspondent current capabilities. The results reported in this thesis provide insight into a number of issues namely: (i) The fundamental limitations on the speed of operation of a bi-layer resistive memory are the time and voltage dependences of the switch-on mechanism. (ii) The results explain the wide spread in switching times reported in the literature and the apparently anomalous behaviour of the high conductance state namely the disappearance of the negative differential resistance region at high voltage scan rates which is commonly attributed to a “dead time” phenomenon which had remained elusive since it was first reported in the ‘60s. (iii) Assuming that the current is filamentary, Comsol simulations were performed and used to explain the observed dynamic properties of the current-voltage characteristics. Furthermore, the simulations suggest that filaments can interact with each other. (iv) The current-voltage characteristics have been studied as a function of temperature. The findings indicate that creation and annihilation of filaments is controlled by filling and neutralizing traps localized at the oxide/polymer interface. (v) Resistive switching was also studied in small-molecule OLEDs. It was shown that the degradation that leads to a loss of light output during operation is caused by the presence of a resistive switching layer. A diagnostic tool that predicts premature failure of OLEDs was devised and proposed. Resistive switching is a property of oxides. These layers can grow in a number of devices including, organic light emitting diodes (OLEDs), spin-valve transistors and photovoltaic devices fabricated in different types of material. Under strong electric fields the oxides can undergo dielectric breakdown and become resistive switching layers. Resistive switching strongly modifies the charge injection causing a number of deleterious effects and eventually device failure. In this respect the findings in this thesis are relevant to understand reliability issues in devices across a very broad field.

The Professionalisation of Non-Denominational Religious Education in England: Politics, Organisation and Knowledge

In response to contemporary concerns, and using neglected primary sources, this article explores the professionalisation of teachers of Religious Education (RI/RE) in non-denominational, state-maintained schools in England. It does so from the launch of Religion in Education (1934) and the Institute for Christian Education at Home and Abroad (1935) to the founding of the Religious Education Council of England and Wales (1973) and the British Journal of Religious Education (1978). Professionalisation is defined as a collective historical process in terms of three inter-related concepts: (1) professional self-organisation and professional politics, (2) professional knowledge, and (3) initial and continuing professional development. The article sketches the history of non-denominational religious education prior to the focus period, to contextualise the emergence of the professionalising processes under scrutiny. Professional self-organisation and professional politics are explored by reconstructing the origins and history of the Institute of Christian Education at Home and Abroad, which became the principal body offering professional development provision for RI/RE teachers for some fifty years. Professional knowledge is discussed in relation to the content of Religion in Education which was oriented around Christian Idealism and interdenominational networking. Changes in journal name in the 1960s and 1970s reflected uncertainties about the orientation of the subject and shifts in understanding over the nature and character of professional knowledge. The article also explores a particular case of resistance, in the late 1960s, to the prevailing consensus surrounding the nature and purpose of RI/RE, and the representativeness and authority of the pre-eminent professional body of the time. In conclusion, the article examines some implications which may be drawn from this history for the prospects and problems of the professionalisation of RE today.
