Avoidance Techniques: State Related Defences in International Antitrust Cases

Despite its economic significance, competition law still remains fragmented, lacking an international framework allowing for dispute settlement. This, together with the growing importance of non-free-market economies in world trade require us to re-consider and re-evaluate the possibilities of bringing an antitrust suit against a foreign state. If the level playing field on the global marketplace is to be achieved, the possibility of hiding behind the bulwark of state sovereignty should be minimised. States should not be free to act in an anti-competitive way, but at present the legal framework seems ill-equipped to handle such challenges.

This paper deals with the defences available in litigation concerning transnational anti-competitive agreements involving or implicating foreign states. Four important legal doctrines are analysed: non-justiciability (political question doctrine), state immunity, act of state doctrine and foreign state compulsion. The paper addresses also the general problem of applicability of competition laws to a foreign state as such. This is a tale about repetitive unsuccessful efforts to sue OPEC and recent attempts in the US to deal with export cartels of Chinese state-owned enterprises

Family, state, class and solidarity: re-conceptualising intergenerational solidarity through the grounded theory approach

The relationship between class and intergenerational solidarities in the public and private spheres calls for further conceptual and theoretical development. This article discusses the findings from the first wave of a qualitative longitudinal study entitled Changing Generations, conducted in Ireland in 2011–2012, comprising 100 in-depth interviews with men and women across the age and socioeconomic spectrums. Constructivist grounded theory analysis of the data gives rise to the following postulates: (1) intergenerational solidarity at the family level is strongly contoured by socioeconomic status (SES); (2) intergenerational solidarity evolves as family generations observe each others’ practices and adjust their expectations accordingly; (3) intergenerational solidarity within families is also shaped by the public sphere (the welfare state) that generates varying expectations and levels of solidarity regarding State supports for different age groups, again largely dependent on SES; (4) the liberal welfare state context, especially at a time of economic crisis, enhances the significance of intergenerational solidarity within families. We conclude by calling for research that is attuned to age/generation, gender and class, and how these operate across the family and societal levels.

On the potential of significance-driven execution for energy-aware HPC

Dynamic Voltage and Frequency Scaling (DVFS) exhibits fundamental limitations as a method to reduce energy consumption in computing systems. In the HPC domain, where performance is of highest priority and codes are heavily optimized to minimize idle time, DVFS has limited opportunity to achieve substantial energy savings. This paper explores if operating processors Near the transistor Threshold Volt- age (NTV) is a better alternative to DVFS for break- ing the power wall in HPC. NTV presents challenges, since it compromises both performance and reliability to reduce power consumption. We present a first of its kind study of a significance-driven execution paradigm that selectively uses NTV and algorithmic error tolerance to reduce energy consumption in performance- constrained HPC environments. Using an iterative algorithm as a use case, we present an adaptive execution scheme that switches between near-threshold execution on many cores and above-threshold execution on one core, as the computational significance of iterations in the algorithm evolves over time. Using this scheme on state-of-the-art hardware, we demonstrate energy savings ranging between 35% to 67%, while compromising neither correctness nor performance.

Key performance indicators – A new approach for specifying concrete and assessing state of health of concrete structure

The focus of this paper is to outline a method for consolidating and implementing the work on performance-based specification and testing. First part of the paper will review the mathematical significance of the variables used in common service life models. The aim is to identify a set of significant variables that influence the ingress of chloride ions into concrete. These variables are termed as Key Performance Indicators (KPI’s). This will also help to reduce the complexity of some of the service life models and make them more appealing for practicing engineers. The second part of the paper presents a plan for developing a database based on these KPI’s so that relationships can then be drawn between common concrete mix parameters and KPI’s. This will assist designers in specifying a concrete with adequate performance for a particular environment. This, collectively, is referred to as the KPI based approach and the concluding remarks will outline how the authors envisage the KPI theory to relate to performance assessment and monitoring.

Phosphatidylethanolamines glycoxidation: products and significance

As fosfatidiletanolaminas constituem a segunda classe de fosfolípidos mais abundantes nos organismos. Elas estão presentes nas membranas biológicas e nas lipoproteínas. As alterações estruturais dos fosfolípidos, ocorrem devido ao stress oxidativo e podem manisfestar-se em alterações das suas propriedades e funções. Já são conhecidas algumas condições fisiopatológicas, nas quais os fosfolípidos oxidados estão envolvidos, por exemplo sinalização celular, resposta imunitária, apoptose e doenças relacionadas com o envelhecimento. Por esse motivo, o interesse no estudo dos fosfolípidos oxidados e suas funções tem crescido nos últimos anos. Contudo, a maioria dos estudos realizados, focam a oxidação das fosfatidilcolinas, tendo sido dedicada pouca atenção a outras classes de fosfolipídos, como as fosfatidiletanolaminas. As fosfatidiletanolaminas, podem ainda sofrer outras modificações, devido ao grupo amina livre presente na cabeça polar, como por exemplo a glicação. As fosfatidiletanolaminas glicadas já foram detectadas em condições de hiperglicemia, em pacientes diabéticos, e tem correlação com a hemoglobina glicada. Sabe-se que a glicação de biomoléculas, pode aumentar as modificações oxidativas, que por sua vez, podem ser responsáveis pelo estado inflamatório, existente na diabetes mellitus. Tanto o stress oxidativo, como a inflamação estão relacionados com a diabetes e as suas complicações. A espectrometria de massa tem sido utilizada como uma importante tecnologia na detecção e caracterização de modificações oxidativas de fosfolípidos. Assim, neste trabalho pretendeu-se estudar as modificações oxidativas induzidas em fosfatidiletanolaminas glicadas, e os seus efeitos biológicos nos monócitos e células dendríticas do sangue periférico. Pretendeu-se ainda, estudar as alterações que ocorreram nas espécies de fosfatidiletanolaminas do fígado de ratos diabéticos. Os resultados obtidos permitiram identificar vários produtos de oxidação de fosfatidiletanolaminas glicadas, nomeadamente novos produtos formados pela oxidação da cabeça polar glicada. A oxidação na cabeça polar glicada foi, ainda, confirmada pela realização de experiências com spin traps combinadas com espetrometria de massa. Posteriormente, as fosfatidiletanolaminas oxidadas, glicadas e glicoxidadas demonstraram ter efeitos pró-inflamatórios, confirmados pelo aumento da estimulação monócitos e de células dendríticas, expresso no aumento do número de células produtoras de citocinas em comparação com o estado basal. As diferentes modificações de fosfatidiletanolaminas induziram estímulos distintos nos dois tipos de células. Sendo as fosfatidiletanolaminas glicadas e as glicoxidadas, os compostos que induziram um maior estímulo. Estes resultados sugeriram que as fosfatidiletanolaminas glicadas e as glicoxidadas podem estar associadas com o estado inflamatório que decorre da hiperglicemia crónica. Ainda, a avaliação do perfil lipídico de extratos de fígado de ratos diabéticos demonstrou que a hiperglicemia induz inúmeras alterações das espécies de fosfatidiletanolaminas e das espécies de outras classes de fosfolípidos, em simultâneo com sinais de lesão hepática. Em conclusão, este trabalho demonstra a relação existente entre, a hiperglicémia, o stress oxidativo, a glicação e oxidação de fosfatidiletanolaminas e ainda a inflamação e compliações diabéticas. Portanto a contribuição da lipidómica é importante para compreender os efeitos prejudiciais da hiperglicemia não controlada, e por isso, merece ser mais explorado.

Biogeochemistry of Paleozoic brachiopods from New York State and Ontario

A comprehensive elemental, isotopic and microstructural analyses was undertaken of brachiopod calcites from the Hamilton Group (Middle Devonian), Clinton Group (Middle Silurian) and Middle to Upper Ordovician strata of Ontario and New York State. The majority of specimens were microstructurally and chemically preserved in a pristine state, although a number of specimens show some degree of post-depositional alteration. Brachiopod calcites from the Hamilton and Clinton Groups were altered by marine derived waters whereas Trenton Group (Middle Ordovician) brachiopods altered in meteorically derived fluids. Analysis of the elemental and isotopic compositions of pristine Hamilton Group brachiopods indicates there are several chemical relationships inherent to brachiopod calcite. Taxonomic differentiation of Mg, Sr and Na contents was evident in three co-occuring species from the Hamilton Group. Mean Mg contents of pristine brachiopods were respectively Athyris spiriferoides (1309ppm), Mucrospirifer mucronatus (1035ppm) and Mediospirifer audacula (789ppm). Similarly, taxonomic differentiation of shell calcite compositions was observed in co-occuring brachiopods from the Clinton Group (Middle Silurian) and the Trenton Group (Middle Ordovician). The taxonomic control of elemental regulation into shell calcite is probably related to the slightly different physiological systems and secretory mechanisms. A relationship was observed in Hamilton Group species between the depth of respective brachiopod communities and their Mg, Sr and Na contents. These elements were depleted in the shell calcites of deeper brachiopods compared to their counterparts in shallower reaches. Apparently shell calcite elemental composition is related to environmental conditions of the depositional setting, which may have controlled the secretory regime, mineral morphology of shell calcite and precipitation rates of each species. Despite the change in Mg, Sr and Na contents between beds and formations in response to environmental conditions, the taxonomic differentiation of shell calcite composition is maintained. Thus, it may be possible to predict relative depth changes in paleoenvironmental reconstructions using brachiopod calcite. This relationship of brachiopod chemistry to depth was also tested within a transgressiveregressive (T-R) cycle in the Rochester Shale Formation (Middle Silurian). Decreasing Mg, Sr and Na contents were observed in the transition from the shallow carbonates of the Irondequoit Formation to the deeper shales of the lowest 2 m of Rochester Shale. However, no isotopic and elemental trends were observed within the entire T-R cycle which suggests that either the water conditions did not change significantly or that the cycle is illusory. A similar relationship was observed between the Fe and Mn chemistries of shell calcite and redox/paleo-oxygen conditions. Hamilton Group brachiopods analysed from deeper areas of the shelf are enriched in Mn and Fe relative to those from shallow zones. The presence of black shales and dysaerobic faunas, during deposition of the Hamilton Group, suggests that the waters of the northern Appalachian Basin were stratified. The deeper brachiopods were marginally positioned above an oxycline and their shell calcites reflect periodic incursions of oxygen depleted water. Furthermore, analysis of Dalmanella from the black shales of the Collingwood Shale (Upper Ordovician) in comparison to those from the carbonates of the Verulam Formation (Middle Ordovician) confirm the relationship of Fe and Mn contents to periodic but not permanent incursions of low oxygen waters. The isotopic compositions of brachiopod calcite found in Hamilton Group (813C; +2.5% 0 to +5.5% 0; 8180 -2.50/00 to -4.00/00) and Clinton Group (813C; +4.00/00 to +6.0; 8180; -1.8% 0 to -3.60/ 00) are heavier than previously reported. Uncorrected paleotemperatures (assuming normal salinity, 0% 0 SMOW and no fractionation effects) derived from these isotopic values suggest that the Clinton sea temperature (Middle Silurian) ranged from 18°C to 28°C and Hamilton seas (Middle Devonian) ranged between 24°C and 29°C. In addition, the isotopic variation of brachiopod shell calcite is significant and is related to environmental conditions. Within a single time-correlative shell bed (the Demissa Bed; Hamilton Group) a positive isotopic shift of 2-2.5% 0 in 013C compositions and a positive shift of 1.0-1.50/00 in 0180 composition of shell calcite is observed, corresponding with a deepening of brachiopod habitats toward the axis of the Appalachian Basin. Moroever, a faunal succession from deeper Ambocoelia dominated brachiopod association to a shallow Tropidoleptus dominated assocation is reflected by isotopic shifts of 1.0-1.50/00. Although, other studies have emphasized the significance of ±20/oo shifts in brachiopod isotopic compositions, the recognition of isotopic variability in brachiopod calcite within single beds and within depositional settings such as the Appalachian Basin has important implications for the interpretation of secular isotopic trends. A significant proportion of the variation observed isotopic distribution during the Paleozoic is related to environmental conditions within the depositional setting.

Effect of mindfulness meditation on the neural substrates of emotion processing and resting state in experienced and beginner meditators

La méditation par le ‘mindfulness’ favorise la stabilité émotionelle, mais les mécanismes neuroneux qui sous-tendent ces effets sont peu connus. Ce projet investiga l’effet du ‘mindfulness’ sur les réponses cérébrales et subjectives à des images négatives, positives et neutres chez des méditants expérimentés et des débutants au moyen de l’imagerie par résonance magnétique fonctionnelle (IRMf). Le ‘mindfulness’ atténua l’intensité émotionelle via différents mécanismes cérébraux pour chaque groupe. Comparés aux méditants, les débutants manifestèrent une déactivation de l’amygdale en réponse aux stimuli émotifs durant le ‘mindfulness’. Comparés aux débutants, les méditants exhibèrent une déactivation de régions du réseau du mode par défaut (RMD) pendant le ‘mindfulness’ pour tous stimuli (cortex médian préfrontal [CMP], cortex cingulaire postérieur [CCP]). Le RMD est constitué de régions fonctionnellement connectées, activées au repos et déactivées lors de tâches explicites. Cependant, nous ne connaissons pas les impacts de l’entraînement par la méditation sur la connectivité entre régions du RMD et si ces effets persistent au-delà d’un état méditatif. La connectivité fonctionnelle entre régions du RMD chez les méditants et débutants au repos fut investiguée au moyen de l’IRMf. Comparés aux débutants, les méditants montrèrent une connectivité affaiblie entre subdivisions du CMP, et une connectivité accrue entre le lobule pariétal inférieur et trois regions du RMD. Ces résultats reflètent que les bienfaits immédiats du ‘mindfulness’ sur la psychopathologie pourraient être dûs à une déactivation de régions limbiques impliquées dans la réactivité émotionelle. De plus, les bienfaits à long-terme de la méditation sur la stabilité émotionelle pourrait être dûs à une déactivation de régions corticales et cingulaires impliquées dans l’évaluation de la signification émotive et une connectivité altérée entre régions du RMD à l’état de repos.

Chit funds contribute to the value of financial markets in India particularly in Kerala. Chit finances with its unique features are of great significance especially as a savings cum borrowing avenue. The present study entitled “A Study of chit Finance in Kerala with special emphasis on Kerala State Financial Enterprises Ltd.” examines the socio-economic aspects of Chit schemes run by the private Chit Funds, KSFE, co-operatives, and informal Chit Funds. The study is an attempt to find the reasons for the growing popularity of Chit Funds as savings cum borrowings avenues even in the presence of various other avenues of savings and borrowings and also to understand how the Chit subscribers utilize the funds. The objectives of the present study are to examine the trends and pattern of growth of Chit Funds in the formal sector in Kerala, performance of KSFE as the only public sector Chit Fund company in India, preference for joining Chit Funds, estimate the cost and return on Chit Funds etc. is an indigenous financial instrument is complementary to modern financial techniques of savings and borrowings. KSFE is the dominant foremen in the chit business in Kerala, its weaknesses result in the non-attainment of certain objectives. Driven by the growing trend of privatization, KSFE needs to be innovative and competitive. It is also necessary that KSFE continue its leadership role by being more effective in being the harbinger of more efficiency, professionalism and good governance in the Chit Fund Industry. The growth and development of chit business by protecting the interests of both the subscribers and the foremen will therefore be most beneficial for any growing economy.

Testing for significance of phase synchronisation dynamics in the EEG

A number of tests exist to check for statistical significance of phase synchronisation within the Electroencephalogram (EEG); however, the majority suffer from a lack of generality and applicability. They may also fail to account for temporal dynamics in the phase synchronisation, regarding synchronisation as a constant state instead of a dynamical process. Therefore, a novel test is developed for identifying the statistical significance of phase synchronisation based upon a combination of work characterising temporal dynamics of multivariate time-series and Markov modelling. We show how this method is better able to assess the significance of phase synchronisation than a range of commonly used significance tests. We also show how the method may be applied to identify and classify significantly different phase synchronisation dynamics in both univariate and multivariate datasets.

Economic valuation of an offshore wind farm in Greece: the role of individual’s base-state influences and beliefs in the value formation process

The increased concern for the impacts of climate change on the environment, along with the growing industry of renewable energy sources, and especially wind power, has made the valuation of environmental services and goods of great significance. Offshore wind energy is being exploited exponentially and its importance for renewable energy generation is increasing. We apply a double-bound dichotomous Contingent Valuation Method analysis in order to both a) estimating the Willingness to Pay (WTP) of Greek residents for green electricity produced by offshore wind farm located between the islands of Tinos and Andros and b) identifying factors behind respondents’ WTP including individual’s behaviour toward environment and individual’s views on climate change and renewable energy. A total of 141 respondents participated in the questionnaire. Results show that the respondents are willing to pay on average 20€ every two months through their electricity bill in return for carbon-free electricity and water saving from the wind farm. Respondents’ environmental consciousness and their perception towards climate change and renewable energy have a positive effect on their WTP.

Permian bivalves of the Taciba Formation, Itarare group, Parana basin, and their biostratigraphic significance

A small and poorly diversified bivalve fauna from Taciba Formation, Itarare Group, Parana Basin (State of Santa Catarina, Mafra Municipality), is described in this paper for the first time, based on new findings. The fauna is recorded in a 30 cm thick interval of fine sandstone locally at the top of Taciba Formation, in the Butia quarry. The studied fossil-bearing sand-stone bed is a marine intercalation recording a brief eustatic rise in sea-level, probably following glacier retreat and climate amelioration at the end of a broad glacial scenario. The fauna is mainly dominated by productid brachiopods, which are not described here, and rare mollusk shells (bivalves and gastropods). Two bivalve species were identified: Myonia argentinensis (Harrington, 1955), and Aviculopecten multiscalptus (Thomas, 1928). The presence of Myonia argentinensis is note-worthy since this species is also present in the Baitaca assemblage found in marine siltstones (Baitaca assemblage) of the Rio do Sul Formation, cropping out at the Teixeira Soares region, Parana State. This species is also recorded in the bivalve fauna from the Bonete Formation, Pillahinco Group, Sauce Grande Basin, Buenos Aires Province, in Argentina. Hence, the marine bivalves of the Taciba Formation are associated with the transgressive event that characterizes the Eurydesma fauna, indicating a Late Asselian-Sakmarian age for the bivalve fauna. Presence of the Myonia argentinensis megadesmid species reinforces the Gondwanic nature of the studied fauna.

Social interactions in Hypsiboas albomarginatus (Anura : Hylidae) and the significance of acoustic and visual signals

Social behavior of Hypsiboas albomarginatus was studied in the Atlantic rain forest, Municipality of Ubatuba, in the north coast of the State of São Paulo, southeastern Brazil. Vocalizations of H. albomarginatus are described, including contexts in which they were emitted and temporal and spectral parameters differentiating advertisement from aggressive calls. Dominant call frequency was inversely correlated with male length and body mass but not with environmental temperature. Number of pulses per note was not correlated with any variable, and advertisement call amplitude was influenced by temperature and time. During chorus aggregation, males interacted acoustically by emitting advertisement calls in antiphony, or by emitting aggressive calls. Some disputes among males culminated in physical combat; males performed kicks and slaps on rivals' heads, in an apparent attempt to dislodge rivals from perches. Visual signals were also displayed during conflicts between males, contributing to an escalation of aggressive behavior. Visual signals were not recorded during courtship between males and females but may help in the accurate localization of the signaling male during aggressive interactions.
