We report four patients who presented with a severe form of metaphyseal chondromatosis in association with D-2-hydroxyglutaric aciduria (D-2-HGA). All patients showed splaying columns of irregular ossification defects with bulbous metaphyses of the long tubular bones, as well as remarkable involvement of the short tubular and flat bones. The vertebral bodies revealed platyspondyly with irregular, stippled endplates. D-2-HGA has been described as a neurometabolic disorder manifesting a broad range of impairment in mental and motor development. Although hydroxyglutaric acid was excreted in high amounts in the urine of all four patients described herein, no significant neurologic abnormalities were evident. This unusual combination of characteristic skeletal and metabolic abnormalities has rarely been reported. Thus, our report will facilitate the recognition of this distinctive entity, and we suggest that a urine organic acid screening be obtained in patients who present with generalized enchondromatosis.

Having lived through a bloody civil war in the 1930s followed by four decades of General Franco’s dictatorship, the Spanish state carried out a transition to a democratic system at the end of the 1970s. The 1978 Constitution was the legal outcome of this transition process. Among other things, it established a territorial model – the so-called “Estado de las Autonomías” (State of Autonomous Communities) – which was designed to satisfy the historical demands for recognition and self-government of, above all, the citizens and institutions of Catalonia and the Basque Country .In recent years support for independence has increased in Catalonia. Different indicators show that pro-independence demands are endorsed by a majority of its citizens, as well as by most of the political parties and organizations that represent its civil society. This is a new phenomenon. Those in favour of independence had been in the minority throughout the 20th century. Nowadays, however, demands of a pro-autonomy and pro-federalist nature, which until recently had been dominant, have gradually lost public support in favour of demands for self-determination and secession. This paper analyses the massive increase in support for secession in Catalonia during the early years of the 21st century. After describing the different theories of secession in plurinational liberal democracies (section 1), we analyse Catalonia’s political evolution over the past decade focusing on the shortcomings with regard to constitutional recognition and accommodation displayed by the Spanish political system. The latter have been exacerbated by the reform process of Catalonia’s Statute of Autonomy (2006) and the subsequent judgement of Spain’s Constitutional Court regarding the aforementioned Statute (2010) (section 2). Finally, we present our conclusions by linking the Catalan case with theories of secession applied to plurinational contexts

Social identity is a double-edged sword. On the one hand, identifying with a social group is a prerequisite for the sharing of common norms and values, solidarity, and collective action. On the other hand, in-group identification often goes together with prejudice and discrimination. Today, these two sides of social identification underlie contradictory trends in the way European nations and European nationals relate to immigrants and immigration. Most European countries are becoming increasingly multicultural, and anti-discrimination laws have been adopted throughout the European Union, demonstrating a normative shift towards more social inclusion and tolerance. At the same time, racist and xenophobic attitudes still shape social relations, individual as well as collective behaviour (both informal and institutional), and political positions throughout Europe. The starting point for this chapter is Sanchez-Mazas' (2004) interactionist approach to the study of racism and xenophobia, which in turn builds on Axel Honneth's (1996) philosophical theory of recognition. In this view, the origin of attitudes towards immigrants cannot be located in one or the other group, but in a dynamic of mutual influence. Sanchez-Mazas' approach is used as a general framework into which we integrate social psychological approaches of prejudice and recent empirical findings examining minority-majority relations. We particularly focus on the role of national and European identities as antecedents of anti-immigrant attitudes held by national majorities. Minorities' reactions to denials of recognition are also examined. We conclude by delineating possible social and political responses to prejudice towards immigrants.

Recognition systems play a key role in a range of biological processes, including mate choice, immune defence and altruistic behaviour. Social insects provide an excellent model for studying recognition systems because workers need to discriminate between nestmates and non-nestmates, enabling them to direct altruistic behaviour towards closer kin and to repel potential invaders. However, the level of aggression directed towards conspecific intruders can vary enormously, even among workers within the same colony. This is usually attributed to differences in the aggression thresholds of individuals or to workers having different roles within the colony. Recent evidence from the weaver ant Oecophylla smaragdina suggests that this does not tell the whole story. Here I propose a new model for nestmate recognition based on a vector template derived from both the individual's innate odour and the shared colony odour. This model accounts for the recent findings concerning weaver ants, and also provides an alternative explanation for why the level of aggression expressed by a colony decreases as the diversity within the colony increases, even when odour is well-mixed. The model makes additional predictions that are easily tested, and represents a significant advance in our conceptualisation of recognition systems.

In a series of three experiments, participants made inferences about which one of a pair of two objects scored higher on a criterion. The first experiment was designed to contrast the prediction of Probabilistic Mental Model theory (Gigerenzer, Hoffrage, & Kleinbölting, 1991) concerning sampling procedure with the hard-easy effect. The experiment failed to support the theory's prediction that a particular pair of randomly sampled item sets would differ in percentage correct; but the observation that German participants performed practically as well on comparisons between U.S. cities (many of which they did not even recognize) than on comparisons between German cities (about which they knew much more) ultimately led to the formulation of the recognition heuristic. Experiment 2 was a second, this time successful, attempt to unconfound item difficulty and sampling procedure. In Experiment 3, participants' knowledge and recognition of each city was elicited, and how often this could be used to make an inference was manipulated. Choices were consistent with the recognition heuristic in about 80% of the cases when it discriminated and people had no additional knowledge about the recognized city (and in about 90% when they had such knowledge). The frequency with which the heuristic could be used affected the percentage correct, mean confidence, and overconfidence as predicted. The size of the reference class, which was also manipulated, modified these effects in meaningful and theoretically important ways.

To compete over limited parental resources, young animals communicate with their parents and siblings by producing honest vocal signals of need. Components of begging calls that are sensitive to food deprivation may honestly signal need, whereas other components may be associated with individual-specific attributes that do not change with time such as identity, sex, absolute age and hierarchy. In a sib-sib communication system where barn owl (Tyto alba) nestlings vocally negotiate priority access to food resources, we show that calls have individual signatures that are used by nestlings to recognize which siblings are motivated to compete, even if most vocalization features vary with hunger level. Nestlings were more identifiable when food-deprived than food-satiated, suggesting that vocal identity is emphasized when the benefit of winning a vocal contest is higher. In broods where siblings interact iteratively, we speculate that individual-specific signature permits siblings to verify that the most vocal individual in the absence of parents is the one that indeed perceived the food brought by parents. Individual recognition may also allow nestlings to associate identity with individual-specific characteristics such as position in the within-brood dominance hierarchy. Calls indeed revealed age hierarchy and to a lower extent sex and absolute age. Using a cross-fostering experimental design, we show that most acoustic features were related to the nest of origin (but not the nest of rearing), suggesting a genetic or an early developmental effect on the ontogeny of vocal signatures. To conclude, our study suggests that sibling competition has promoted the evolution of vocal behaviours that signal not only hunger level but also intrinsic individual characteristics such as identity, family, sex and age.

We investigate the coevolution between philopatry and altruism in island-model populations when kin recognition occurs through phenotype matching. In saturated environments, a good discrimination ability is a necessary prerequisite for the emergence of sociality. Discrimination decreases not only with the average phenotypic similarity between immigrants and residents (i.e., with environmental homogeneity and past gene flow) but also with the sampling variance of similarity distributions (a negative function of the number of traits sampled). Whether discrimination should rely on genetically or environmentally determined traits depends on the apportionment of phenotypic variance and, in particular, on the relative values of e (the among-group component of environmental variance) and r (the among-group component of genetic variance, which also measures relatedness among group members). If r exceeds e, highly heritable cues do better. Discrimination and altruism, however, remain low unless philopatry is enforced by ecological constraints. If e exceeds r, by contrast, nonheritable traits do better. High e values improve discrimination drastically and thus have the potential to drive sociality, even in the absence of ecological constraints. The emergence of sociality thus can be facilitated by enhancing e, which we argue is the main purpose of cue standardization within groups, as observed in many social insects, birds, and mammals, including humans.

The ability of group members to discriminate against foreigners is a keystone in the evolution of sociality. In social insects, colony social structure (number of queens) is generally thought to influence abilities of resident workers to discriminate between nestmates and non-nestmates. However, whether social origin of introduced individuals has an effect on their acceptance in conspecific colonies remains poorly explored. Using egg-acceptance bioassays, we tested the influence of social origin of queen-laid eggs on their acceptance by foreign workers in the ant Formica selysi. We showed that workers from both single- and multiple-queen colonies discriminated against foreign eggs from single-queen colonies, whereas they surprisingly accepted foreign eggs from multiple-queen colonies. Chemical analyses then demonstrated that social origins of eggs and workers could be discriminated on the basis of their chemical profiles, a signal generally involved in nestmate discrimination. These findings provide the first evidence in social insects that social origins of eggs interfere with nestmate discrimination and are encoded by chemical signatures.

Tako-tsubo cardiomyopathy or "transient left ventricular (LV) apical ballooning" clinically presents like acute myocardial infarction without angiographic stenosis on coronary angiogram and a transient (reversible) LV apical ballooning. We discuss here about a 56-year-old woman complains of first constrictive chest pain with ST elevation in leads V2-V6 and minimal enzymatic release. Coronary angiogram demonstrates vessels without stenosis and the left ventriculogram an extensive LV apical wall motion abnormalities. LV dysfunction will only be transient since 24 hours after admission echographic images demonstrate quite complete recovery of LV systolic function. The pain disappears 12 hours after admission and the creatine kinase level normalize after 48 hours.

CD8(+) cytotoxic T lymphocytes (CTL) can recognize and kill target cells expressing only a few cognate major histocompatibility complex (MHC) I-peptide complexes. This high sensitivity requires efficient scanning of a vast number of highly diverse MHC I-peptide complexes by the T cell receptor in the contact site of transient conjugates formed mainly by nonspecific interactions of ICAM-1 and LFA-1. Tracking of single H-2K(d) molecules loaded with fluorescent peptides on target cells and nascent conjugates with CTL showed dynamic transitions between states of free diffusion and immobility. The immobilizations were explained by association of MHC I-peptide complexes with ICAM-1 and strongly increased their local concentration in cell adhesion sites and hence their scanning by T cell receptor. In nascent immunological synapses cognate complexes became immobile, whereas noncognate ones diffused out again. Interfering with this mobility modulation-based concentration and sorting of MHC I-peptide complexes strongly impaired the sensitivity of antigen recognition by CTL, demonstrating that it constitutes a new basic aspect of antigen presentation by MHC I molecules.

The coreid Leptoglossus zonatus (Dallas, 1852) is commonly found in corn (Zea mays L.) fields in Brazil, and it has been observed flying and landing on objects or persons near these fields. During January, 1995, this behavior was studied in corn plantations. Results indicated that the bugs concentrated on objects (plastic cylinders traps) introduced into their habitat and that their number increased during the first 24 hs. However, as time passed (8 days), this possible territorial or recognition behavior gradually decreased, and tended to disappear.

A mudança do normativo contabilístico ocorrido em 2009, alterou o paradigma de reconhecimento e mensuração de activos. Embora a natureza das operações contínua presente no processo contabilístico, muitas coisas foram alteradas tendo em conta a substância da informação e a sua realidade económica. O caso dos contratos de concessão é disto um bom exemplo. Há casos em que no normativo anterior eram reconhecidos como activos fixos tangíveis e actualmente são reconhecidos como intangíveis. O estudo em causa tem como objetivo principal analisar o conceito dos contratos de concessão, bem como os procedimentos para o reconhecimento, mensuração e divulgação nas demonstrações financeiras. Considerados activos intangíveis (de facto a entidade acaba por ter um “Direito” de explorar um determinado activo), o processo contabilístico é feito a luz do disposto na Norma de Relato Financeiro nº6 – Activos Intangíveis. Os contractos de concessão apresentam especificidades próprias e por esta razão o IASB emitiu uma IFRIC (nº 12) com o objectivo de clarificar o tratamento contabilístico desta problemática. Não existindo no normativo nacional tal norma interpretativa as empresas nacionais que convivem com esta realidade vêem-se na contingência de, supletivamente, recorrer às normas internacionais de contabilidade para resolver o assunto. É o caso da ELECTRA para os activos afectos a distribuição. Neste sentido, o estudo debruça sobre esta problemática, apresenta um enquadramento teórico, analisar os principais aspectos de reconhecimento a luz dos dois normativos contabilísticos nacionais (o antigo Plano Nacional de Contabilidade e o actual Sistema de Normalização Contabilística e de Relato Financeiro) e termina utilizando as informações da ELECTRA, SARL para ilustrar este processo de reconhecimento contabilístico. The change of a the accounting regulatory occurred in 2009, changed the paradigm for recognizing and measuring assets. Although the continuous nature of the operations in this accounting process, many things have changed in view of the substance of information and its economic reality. The case of concession contracts, it is a good example. There are cases where the former were recognized as legal and tangible fixed assets are currently recognized as intangible assets. The study is aimed to analyzing the concept of concession contracts, as well as procedures for the recognition, measurement and disclosure in the financial statements. Considered intangible assets (in fact the entity turns out to have a “right” to exploit a particular asset) the accounting process is done in light of the provisions of Financial Reporting Standard No. 6 – Intangible Assets. The concession contracts have specific characteristics and for this reason the IASB issued IFRIC one (Ner. 12 ) in order to clarify the accounting treatment of this problem. In the absence of such a standard national regulatory interpretative national companies that live with this reality find themselves in contingency, additionally, make use of international accounting standards to resolve the matter. ELECTRA is the case of the assets connected to the distribution. In this sense, the study focuses on this issue, presents a theoretical framework to analyze the main aspects of recognition light of both national accounting standards (formerly the National Accounting Standards and the current system of accounting and financial reporting) and ends up using the information the Electra SARL to illustrate this process of accounting recognition.
