A afluência de imigrantes a Portugal, nas últimas três décadas transformou radicalmente todo o tecido social português, caracterizando-se hoje pela sua heterogeneidade. Até ao início da década de 90 do século XX, os fluxos migratórios provinham essencialmente dos Países de Língua Oficial Portuguesa, com maior incidência de Cabo Verde, Brasil e Angola. É nessa década que se registam movimentos bastante significativos de imigrantes provenientes da Europa Central e Oriental, principalmente da Ucrânia, Rússia, Roménia e Moldávia, assim como da Ásia, destacando-se os naturais da China, Índia, Paquistão e das antigas repúblicas soviéticas. De acordo com a análise apresentada pelo Instituto Nacional de Estatística em Dezembro de 2006, residiam de forma legal em Portugal 329 898 cidadãos de nacionalidade estrangeira, sendo as maiores comunidades de Cabo Verde (57 349), Brasil (41 728) e Angola (28 854). A sociedade portuguesa do século XXI, distancia-se cada vez mais do conceito de monolinguismo, tal como se evidencia no Projecto Gulbenkian “Diversidade Linguística na Escola Portuguesa”, que, segundo o estudo feito, onze por cento dos alunos residentes na área da Grande Lisboa nasceram fora de Portugal e têm como línguas maternas cinquenta e oito idiomas. É urgente uma intervenção diferente no que corresponde a esta nova realidade linguística em Portugal e sobretudo no que concerne à integração do “outro”, reconhecendo e respeitando as várias línguas maternas e culturas, como também a sua preservação a fim de possibilitar o desenvolvimento íntegro e harmonioso da identidade. A heterogeneidade da actual sociedade portuguesa impõe um olhar atento para com esta nova realidade no país, sobretudo em muitas das escolas onde a par do uso da língua portuguesa outras línguas são também usadas como forma de comunicação entre os mesmos pares, situação esta perfeitamente desajustada da realidade escolar madeirense Estudo de caso: O uso da Língua Portuguesa por jovens oriundos de outros países nos domínios privado, público e educativo. 10 de inícios da década de 90 do século XX, à excepção dos alunos provenientes da Venezuela, os denominados luso-descendentes. A escola mudara, tudo se alterara, havia que tentar perceber o que estava a ocorrer, um novo Mundo “invadira” as turmas, prontas a aprender, a saber, a descobrir. Era preciso preencher o silêncio expectante. Aprender uma nova língua, a portuguesa, decorrente da obrigatoriedade implícita de tratar-se da língua oficial, obrigava a repensar o ensino, a continuamente desvendar novos caminhos possibilitadores de encontro entre a língua materna e a segunda, de reencontro com a identidade linguística e cultural que não se quer perdidas, só tornado possível na diferença. A par de uma escola que se apresentava de forma diferente, cuja intervenção teria de ser oposta à de então, uma vez que a aprendizagem do português era feita como língua segunda (L2), muitas foram e são as inquietações, um turbilhão de interrogações decorriam deste contacto constante de uma língua que se diz minha, fonte de partilha com outros jovens. O uso da língua portuguesa confinar-se-á unicamente à escola com os professores e colegas ou despoletará curiosidades, vontades, interesses, motivados por objectivos confinados ao percurso e à história humana? Muitas são as interrogações que ocorrem, muitos são também os momentos de sabedoria mútua de línguas e países a desvendar num contínuo ininterrupto e é essa constante procura que determina a busca de respostas. Entre muitas interrogações uma afigurava-se de forma latente, quiçá fonte de resposta para outras interrogações inerentes à língua portuguesa como língua segunda. A sua utilização por parte dos alunos de outras nacionalidades nos domínios privado, público e educativo engloba domínios diversos capazes de informar acerca do uso dessa mesma língua. Importa no entanto reforçar que estes alunos constituem um grupo heterogéneo sob diversos pontos de vista: etário, linguístico e cultural. Do ponto de vista linguístico a população que tem o português como língua segunda abrange alunos falantes de diferentes línguas maternas, umas mais próximas, outras mais afastadas do português, propiciando diferentes graus de transferência de conhecimentos linguísticos e de experiências comunicativas, como também em diferentes estádios de aquisição e que fora da escola o usam em maior ou menor número de contextos e com um grau de frequência desigual. Estudo de caso: O uso da Língua Portuguesa por jovens oriundos de outros países nos domínios privado, público e educativo. 11 Dispõem também de diferentes capacidades individuais para discriminar, segmentar e produzir sequências linguísticas. Já do ponto de vista cultural apresentam diferentes hábitos de aprendizagem, bem como diferentes representações e expectativas face à escola. Todos estes factores determinarão ritmos de progressão distintos no que respeita à aprendizagem do português como língua segunda. As oportunidades de aprendizagem e de uso que cada indivíduo tem ao longo da vida, determinantes no processo de aquisição, desenvolvimento e aprendizagem de uma língua, variam bastante de indivíduo para indivíduo. Os alunos podem viver num mesmo contexto no entanto razões variadíssimas determinarão diferentes oportunidades de aprendizagem e de uso. Viver-se num contexto de imersão não é suficiente para que todos tenham o mesmo grau de exposição a material linguístico rico e variado da L2. Essas oportunidades também se relacionam com a distância linguística entre língua primeira (L1) e a língua segunda, quanto mais afastadas são as duas línguas mais os falantes da L2 se refugiam na sua língua materna, assim como também se associam aos hábitos culturais da comunidade e da família.

The concept of autism is reviewed in its historical evolution. It is suggested that the Bleulerian insistence on the withdrawal component in autism contributed to the decline of its use in adult psychiatry. Phenomenology offers another approach to grasping the nature of autism as a relational (subject-outer world) phenomenon. European phenomenological psychiatry in the field of schizophrenia is introduced and its attempts to reveal the essence of autism are presented. Autism is here considered as a "loss of vital contact with reality" (Minkowski), "inconsistency of natural experience" (Binswanger), or "the global crisis of common sense" (Blankenburg). It is proposed that autism represents dysfunctional perceptual/expressive attunement to the outer world. The usefulness of this concept is briefly examined in relation to the diagnosis and etiopathogenesis of schizophrenia.

We discuss reality conditions and the relation between spacetime diffeomorphisms and gauge transformations in Ashtekars complex formulation of general relativity. We produce a general theoretical framework for the stabilization algorithm for the reality conditions, which is different from Diracs method of stabilization of constraints. We solve the problem of the projectability of the diffeomorphism transformations from configuration-velocity space to phase space, linking them to the reality conditions. We construct the complete set of canonical generators of the gauge group in the phase space which includes all the gauge variables. This result proves that the canonical formalism has all the gauge structure of the Lagrangian theory, including the time diffeomorphisms.

Bioterrorism literally means using microorganisms or infected samples to cause terror and panic in populations. Bioterrorism had already started 14 centuries before Christ, when the Hittites sent infected rams to their enemies. However, apart from some rare well-documented events, it is often very difficult for historians and microbiologists to differentiate natural epidemics from alleged biological attacks, because: (i) little information is available for times before the advent of modern microbiology; (ii) truth may be manipulated for political reasons, especially for a hot topic such as a biological attack; and (iii) the passage of time may also have distorted the reality of the past. Nevertheless, we have tried to provide to clinical microbiologists an overview of some likely biological warfare that occurred before the 18th century and that included the intentional spread of epidemic diseases such as tularaemia, plague, malaria, smallpox, yellow fever, and leprosy. We also summarize the main events that occurred during the modern microbiology era, from World War I to the recent 'anthrax letters' that followed the World Trade Center attack of September 2001. Again, the political polemic surrounding the use of infectious agents as a weapon may distort the truth. This is nicely exemplified by the Sverdlovsk accident, which was initially attributed by the authorities to a natural foodborne outbreak, and was officially recognized as having a military cause only 13 years later.

Major life history traits, such as fecundity and survival, have been consistently demonstrated to covary positively in nature, some individuals having more resources than others to allocate to all aspects of their life history. Yet, little is known about which resources (or state variables) may account for such covariation. Reactive oxygen species (ROS) are natural by-products of metabolism and, when ROS production exceeds antioxidant defenses, organisms are exposed to oxidative stress that can have deleterious effects on their fecundity and survival. Using a wild, long-lived bird, the Alpine Swift (Apus melba), we examined whether individual red cell resistance to oxidative stress covaried with fecundity and survival. We found that males that survived to the next breeding season tended to be more resistant to oxidative stress, and females with higher resistance to oxidative stress laid larger clutches. Furthermore, the eggs of females with low resistance to oxidative stress were less likely to hatch than those of females with high resistance to oxidative stress. By swapping entire clutches at clutch completion, we then demonstrated that hatching failure was related to the production of low-quality eggs by females with low resistance to oxidative stress, rather than to inadequate parental care during incubation. Although male and female resistance to oxidative stress covaried with age, the relationships among oxidative stress, survival, and fecundity occurred independently of chronological age. Overall, our study suggests that oxidative stress may play a significant role in shaping fecundity and survival in the wild. It further suggests that the nature of the covariation between resistance to oxidative stress and life history traits is sex specific, high resistance to oxidative stress covarying primarily with fecundity in females and with survival in males.

A study was undertaken to determine if there was a relation between the mode of colony founding in ants and the physiology of the new queens produced, in which mature gynes of 24 ant species were examined. Gynes of species utilizing independent colony founding had a far higher relative fat content (X±SD; 54±6%)(g fat/g dry weight) than gynes of species employing dependent colony founding(19±8%). Dimorphism between queens and workers was significantly higher in species employing independent colony founding. Thus independent colony founding not only results in production of queens with a relatively higher fat content and therefore with a higher energy content per g, but also results in the production of larger queens (in comparison with worker size). Of species employing independent colony founding, 80% were monogynous, whereas only 11% of the species employing dependent colony founding were monogynous. These results are discussed with regard to the social structure and life-history of ant species.

Los manuales de historia de la lingüística tratan del mito bíblico de Babel y del nacimiento de la gramática en Alejandría de manos de Dionisio de Tracia. Estos pasajes de la historia, que corresponden a épocas diferentes, remiten a dos problemas fundamentales de la lingüística: por una parte, el origen del lenguaje y la diversidad lingüística; por la otra, la invención de la gramática como instrumento para la edición de textos y para el conocimiento formal de la lengua. Pese a las diferencias, Babel y la biblioteca de Alejandría tienen en común una naturaleza mítica. Sus relatos contienen elementos de la ficción y de la realidad que suelen pasar desapercibidos. El artículo señala estos elementos y establece ciertas afinidades entre Babel y la biblioteca, de suerte que articulados componen un ciclo narrativo. // Abstract.- Babel and the Library, the myth masks in Linguistics. History textbooks of linguistics explain the biblical myth of Babel and the birth of grammar in Alexandria at the hands of Dionysius Thrax. These passages of history, which correspond to different times, refer to two fundamental problems of linguistics: first, the origin of language and linguistic diversity and on the other, the invention of grammar as a tool for text editing and formal knowledge of the language. Despite the differences, Babel and the library of Alexandria share a mythical nature. These stories contain elements of fiction and reality that often go unnoticed. The article points out these elements and establishes affinities between Babel and the library, so that it should be considered as a narrative cycle. Keywords: Babel, Library of Alexandria, myth, story, grammar, institution, Dionysius Thrax.

The mating behavior and reproductive strategies of Alpine whitefish like Coregonus zugensis (Nusslin) are poorly understood, probably because they spawn in deep water where direct observations are difficult. In this study, we interpret life-history and sperm quality traits of fish that we caught from their spawning place. We found that males invest heavily into gonadal tissue (up to 5.6% of their body weight), which is, in comparison to other fish, consistent with external fertilization, distinct pairing and moderate to high communal spawning, or no pairing and low to moderate communal spawning. Sperm competition theory and recent experimental studies on other salmonids predict that males optimize ejaculate characteristics in relation to the costs of sperm and the level of competition they have to expect: dominant males are predicted to invest less into ejaculate quality and to have slower spermatozoa than subdominant males. We found that spermatozoa of older males are slower than those of younger males. Moreover, older males have larger breeding tubercles, a secondary sexual trait that has, in some previous studies, been found to be linked to good condition and to good genetic quality. Our results suggest that C. zugensis has age-linked reproductive strategies, that multimale spawning is common, i.e., that sperm competition plays a significant role, and that older males are on average dominant over younger males at the spawning place.

BACKGROUND: The risk of many cancers is higher in subjects with a family history (FH) of cancer at a concordant site. However, few studies investigated FH of cancer at discordant sites. PATIENTS AND METHODS: This study is based on a network of Italian and Swiss case-control studies on 13 cancer sites conducted between 1991 and 2009, and including more than 12 000 cases and 11 000 controls. We collected information on history of any cancer in first degree relatives, and age at diagnosis. Odds ratios (ORs) for FH were calculated by multiple logistic regression models, adjusted for major confounding factors. RESULTS: All sites showed an excess risk in relation to FH of cancer at the same site. Increased risks were also found for oral and pharyngeal cancer and FH of laryngeal cancer (OR = 3.3), esophageal cancer and FH of oral and pharyngeal cancer (OR = 4.1), breast cancer and FH of colorectal cancer (OR = 1.5) and of hemolymphopoietic cancers (OR = 1.7), ovarian cancer and FH of breast cancer (OR = 2.3), and prostate cancer and FH of bladder cancer (OR = 3.4). For most cancer sites, the association with FH was stronger when the proband was affected at age <60 years. CONCLUSIONS: Our results point to several potential cancer syndromes that appear among close relatives and may indicate the presence of genetic factors influencing multiple cancer sites.

Abstract The maintenance of genetic variation is a long-standing issue because the adaptive value of life-history strategies associated with each genetic variant is usually unknown. However, evidence for the coexistence of alternative evolutionary fixed strategies at the population level remains scarce. Because in the tawny owl (Strix aluco) heritable melanin-based coloration shows different physiological and behavioral norms of reaction, we investigated whether coloration is associated with investment in maintenance and reproduction. Light melanic owls had lower adult survival compared to dark melanic conspecifics, and color variation was related to the trade-off between offspring number and quality. When we experimentally enlarged brood size, light melanic males produced more fledglings but in poorer condition, and they were less often recruited in the local breeding population than those of darker melanic conspecifics. Our results also suggest that dark melanic males allocate a constant effort to raise their brood independently of environmental conditions, whereas lighter melanic males finely adjust reproductive effort in relation to changes in environmental conditions. Color traits can therefore be associated with life-history strategies, and stochastic environmental perturbation can temporarily favor one phenotype over others. The existence of fixed strategies implies that some phenotypes can sometimes display a "maladapted" strategy. Long-term population monitoring is therefore vital for a full understanding of how different genotypes deal with trade-offs.

Background We analyzed the relationship between cholelithiasis and cancer risk in a network of case-control studies conducted in Italy and Switzerland in 1982-2009. Methods The analyses included 1997 oropharyngeal, 917 esophageal, 999 gastric, 23 small intestinal, 3726 colorectal, 684 liver, 688 pancreatic, 1240 laryngeal, 6447 breast, 1458 endometrial, 2002 ovarian, 1582 prostate, 1125 renal cell, 741 bladder cancers, and 21 284 controls. The odds ratios (ORs) were estimated by multiple logistic regression models. Results The ORs for subjects with history of cholelithiasis compared with those without were significantly elevated for small intestinal (OR = 3.96), prostate (OR = 1.36), and kidney cancers (OR = 1.57). These positive associations were observed ≥10 years after diagnosis of cholelithiasis and were consistent across strata of age, sex, and body mass index. No relation was found with the other selected cancers. A meta-analysis including this and three other studies on the relation of cholelithiasis with small intestinal cancer gave a pooled relative risk of 2.35 [95% confidence interval (CI) 1.82-3.03]. Conclusion In subjects with cholelithiasis, we showed an appreciably increased risk of small intestinal cancer and suggested a moderate increased risk of prostate and kidney cancers. We found no material association with the other cancers considered.

The passionate and deceptive life stories of the protagonists in Angela Carter’s Wise Children (1990) and Rose Tremain’s The Cupboard (1984), women in their seventies and eighties, are entangled with historical events that influenced England, Europe and the rest of the world. In these novels, Angela Carter and Rose Tremain challenge not only notions of ageing by presenting elder protagonists who are lively and strong, but also the idea of history as unique, true and unquestionable by conferring on them the status of story and historytellers.

Background: Studies have found higher levels of insecure attachment in individuals with schizophrenia. Attachment theory provides a framework necessary for conceptualizing the development of interpersonal functioning. Some aspects of the attachment of the believer to his/her spiritual figure are similar to those between the child and his/her parents. The correspondence hypothesis suggests that early child-parent interactions correspond to a person's relation to a spiritual figure. The compensation hypothesis suggests that an insecure attachment history would lead to a strong religiousness/spirituality as a compensation for the lack of felt security. The aim of this study is to explore attachment models in psychosis vs. healthy controls, the relationships between attachment and psychopathology and the attachment processes related to spiritual figures. Methods: Attachment models were measured in 30 patients with psychosis and 18 controls with the AAI (Adult Attachment interview) in relationship with psychopathology. Beliefs and practices related to a spiritual figure were investigated by qualitative and quantitative analyses. Results: Patients with psychosis showed a high prevalence of insecure avoidant attachment. Spiritual entities functioned like attachment figures in two thirds of cases. Interviews revealed the transformation of internal working models within relation to a spiritual figure: a compensation process was found in 7 of the 32 subjects who showed a significant attachment to a spiritual figure. Conclusions: Attachment theory allows us to highlight one of the underlying dimensions of spiritual coping in patients with psychosis.

This article analyses the cómic book Maus, by Art Spiegelman (1986-1991), from two angles: as a work of art dealing with the Holocaust, and as a cómic that subverts the fictional tradition of the genre, opening itself up to history and the narration of reality. Maus, the first cómic book to treat the topic of the Holocaust in depth, was written by a second-generation witness. It is a story of both physical survival and enduring trauma in the family. At the same time, an analysis of the stratevival and enduring trauma in the family. At the same time, an analysis of the strateof the traditional cómic reveals how Spiegelman has used the genre to recount, instead of fiction and for the first time, a historically authentic biographical tale
