The author gives a brief history of psychiatry in Quebec and attempts to show that economic factors influence social evolution. After having shown that the costs of mental health reach $ 500 millions, he makes an appeal for the rationalization of services in this time of economic austerity.
The early education of the trisomic child, through simple and often repeated advice, makes it possible to avoid the recurrence of educational errors linked to parental uncertainties. Such an educational package, presented in the form of games and play, should be implemented very early, and if possible before the sixth month. Linguistic work will cover the aspects of psychomotor awakening, the preparation of pre-language, the acquisition of the landmarks that are essential for any form of communication and practical advice to the mother. The initial stage of social rehabilitation involves the integration of the child in its own family. Between the age of 18 months and 3 years, a social evolution with a regular rhythm is proposed thanks to the possibilities offered by crèches and day-care centres. Around the age of 3 years old, school becomes the logical next step towards such rehabilitation.
In Niger, systemic hypertension is responsible for almost 10 p. 100 of the hospital admittances, and for 1 out of 2 or 3 cases of cardiovascular disease. There is no patent correlation with sex, except that the age of maximal frequency is between 40 and 50 for females and after 50 for males. Clinical and etiological features are conventional but present two original points: the young age of many patients, and the frequency of intestinal nephropathies. As Nigerian patients are often middle-class people or civil-servants, one may suspect a correlation between frequency of systemic hypertension and social evolution.
INTRODUCTION AND OBJECTIVE: Approximately 400,000 years ago men started to use language. Initially it was probably poor with few phonemes. With social evolution it became more complex, with the appearance of new phonemes and a more complete grammatical structure. The current concept of the processing of language dates, with little change, from the nineteenth century. DEVELOPMENT: With the birth of phrenology language began to be studied. This lead to the hypothesis of Wernicke, with two main areas joined by the fasciculo arcuato, which is still held to be valid with modifications by Gerchwind and Damasio, amongst others. Important advances in the study of language are due to Chomsky and his transformational grammar. This supports the universal structure of language, since one learns it following genetically determined laws. Language has three main aspects: creativity which makes both the transmitter and the receiver active participants in communication, the form from which words are constructed and the content of the message. Aphasia is an alteration in the comprehension and understanding of language, which may be the clinical expression of many different aetiologies. They help us to localize the lesion topographically. They are divided depending on the clinical signs, into motor or Broca's aphasia, in which understanding is conserved but the patient uses a language with poor grammatical structure, although the semantic content is acceptable: sensitive or Wernicke's aphasia, with inability to understand and language which is fluid but unintelligible; conduction aphasia due to limitation in the transmission of impulses from Wernicke's area to that of Broca, with acceptable understanding and fluid language and the trans-cortical aphasias where the main characteristic is indemnity of the capacity of repetition. CONCLUSIONS: The aphasias, as the expression of an alteration of language are an important support in the topographical localization of lesions, even before these can be shown on computerized tomography.
The evolution of altruistic behavior through group selection is generally viewed as possible in theory but unlikely in reality, because individual selection favoring selfish strategies should act more rapidly than group selection favoring cooperation. Here we demonstrate the evolution of altruism, in the form of conditional reproductive restraint based on an explicitly social mechanism, modulated by intrapopulation communication comprising signal and evolved response, in a spatially distributed predatory/parasitic/pathogenic model system. The predatory species consistently comes to exploit a signal implying overcrowding, individuals constraining their reproduction in response, with a corresponding increase in equilibrium reproduction rate in the absence of signal. This signaled restraint arises in a robust way for a range of model spatial systems; it outcompetes non-signal-based restraint and is not vulnerable to subversion by noncooperating variants. In these systems, communication is used to evaluate population density and regulate reproduction accordingly, consistent with central ideas of Wynne-Edwards [Wynne-Edwards, V. C. (1962) Animal Dispersion in Relation to Social Behavior (Hafner, New York)], whose claims about the evolutionary importance of group selection helped ignite decades of controversy. This quantitative simulation model shows how the key evolutionary transition from solitary living to sociality can occur. The process described here of cooperation evolving through communication may also help to explain other major evolutionary transitions such as intercellular communication leading to multicellular organisms.
We present a simple deterministic and based on local rules model of evolving social network, which leads to a network with the properties of a real social system, e.g., small-world topology and assortative mixing. The state of an individual Si is characterized by the values of Q cultural features, drawn from Gaussian distribution with variance sigma. The other control parameter is sociability Ti, which describes the maximal number of connections of an individual. The state of individuals and connections between them evolve in time. As results from numerical computations, an initial diversity of cultural features in a community has an essential influence on an evolution of social network. It was found that for a critical value of control parameter sigma c(Q) there is a structural transition and a hierarchical network with small-world topology of connections and a high clustering coefficient emerges. The emergence of small-world properties can be related to the creation of subculture groups in a community. The power-law relation between the clustering coefficient of a node and its connectivity C(k) approximately k-beta was observed in the case of a scale-free distribution of sociability Ti and a high enough cultural diversity in a population.
The use of social validation procedures has become widespread in recent years. Although most researchers have used social validation procedures to select target behaviors and to evaluate whether the changes produced by a treatment program should be considered socially useful, little attention has been focused upon using the social validation process to determine the optimal levels for target behaviors. This paper suggests several ways in which social validation procedures can be employed in order to select when and how much to change target behaviors.

The evolution of female multiple mating is a highly controversial topic, especially in social insects. Here we analyze, using comparative analyses and simulation models, the merits of two major contending hypotheses for the adaptive value of polyandry in this group. The hypotheses maintain that, respectively, the resulting genotypic diversity among offspring within a colony: (1) mitigates against the effects of parasites; or (2) favors adaptive division of labor. Only two of 11 phylogenetically uncontrolled comparative analyses supported an association between polyandry and the complexity of division of labor (measured here using worker caste polymorphism or polyethism) as proposed by hypothesis 2, and after controlling for phylogeny there were no significant associations. In contrast, a previous study demonstrated such an association for parasite load as expected under hypothesis 1. In addition, we used simulation models to track the spread of an initially rare allele for double mating in a population of single-mating alleles, thus analyzing the crucial first step from monandry to polyandry. We find that double mating evolves consistently under antagonistic coevolution given that parasites exert sufficient selection intensity. In contrast, selection for enhanced division of labor resulted in only an erratic appearance of polyandry in highly (and mostly negatively) autocorrelated environments where no coevolutionary dynamics were allowed. Together, we interpret these results to suggest that parasites, and the antagonistic coevolutionary pressures they exert, may play an important role in the evolution of polyandry in social hymenopteran populations.
The social support networks of a group of low socio-economic status (S.E.S.) mothers (n = 87) and a group of higher S.E.S. mothers (n = 44) are described and compared at the 30th week of pregnancy and at the third week after the birth of their first baby. The evolution of the support networks for these two groups of mothers during this period is also examined. A modified form of the ASSIS from Barrera has been used to measure the social support network. Results show that, during pregnancy, the social support network of low-S.E.S. mothers is more restricted than that of higher S.E.S. mothers. Although the actual number of people around them after the birth of the baby did not increase, low-S.E.S. mothers said they felt a slight increase in the number of people available to give support in some way. They also reported that conflicts were more frequent with some of them. For higher S.E.S. mothers, all social network variables remained stable from pregnancy through the first postpartum month.

Halminton (1) was apparently the first to appreciate that the synthesis of Mendelian genetics with Darwin's theory of natural selection had profound implications for social theory. In particular, insofar as almost all social behavior is either selfish or altruistic (or has such effects), genetical reasoning suggests that an individual's social behavior should be adjusted to his or her degree of relatedness, r, to all individuals affected by the behavior. We call this theory kinship theory. The social insects provide a critical test of Hamilton's kinship theory. When such theory is combined with the sex ratio theory of Fisher (9), a body of consistent predictions emerges regarding the haplodiploid Hymenoptera. The evolution of female workers helping their mother reproduce is more likely in the Hymenoptera than in diploid groups, provided that such workers lay some of the male-producing eggs or bias the ratio of investment toward reproductive females. Once eusocial colonies appear, certain biases by sex in these colonies are expected to evolve. In general, but especially in eusocial ants, the ratio of investment should be biased in favor of females, and in it is expected to equilibrate at 1 : 3 (male to female). We present evidence from 20 species that the ratio of investment in monogynous ants is, indeed, about 1 : 3, and we subject this discovery to a series of tests. As expected, the slave-making ants produce a ratio of investment of 1 : 1, polygynoys ants produce many more males than expected on the basis of relative dry weight alone, solitary bees and wasps produce a ratio of investment near 1 : 1 (and no greater than 1 : 2), and the social bumblebees produce ratios of investment between 1 : 1 and 1 : 3. In addition, sex ratios in monogynous ants and in trapnested wasps are, as predicted by Fisher, inversely related to the relative cost in these species of producing a male instead of a female. Taken together, these data provide quantitative evidence in support of kinship theory, sex ratio theory, the assumption that the offspring is capable of acting counter to its parents' best interests, and the supposition that haplodiploidy has played a unique role in the evolution of the social insects. Finally, we outline a theory for the evolution of worker-queen conflict, a theory which explains the queen's advantage in competition over male-producing workers and the workers' advantage regarding the ratio of investment. The theory uses the asymmetries of haplodiploidy to explain how the evolved outcome of parent-offspring conflict in the social Hymenoptera is expected to be a function of certain social and life history parameters.

Male homosexuality has been viewed by evolutionary psychologists as a Darwinian paradox, and by other social scientists as a social construction. We argue that it is better understood as an evolutionary social construction. Male homosexuality as we now know it is an 18th-century invention, but nonexclusive same-sex sexual behavior has a long evolutionary history. According to the alliance-formation hypothesis, same-sex sexuality evolved by natural selection because it created or strengthened male-male alliances and allowed low-status males to reposition themselves in the group hierarchy and thereby increase their reproductive success. This hypothesis makes sense of some odd findings about male homosexuality and helps to explain the rise in exclusive male homosexuality in the 18th century. The sociohistorical conditions around 1700 may have resulted in an increase in same-sex sexual behavior. Cultural responses to same-sex sexuality led to the spread of exclusive homosexual behavior and to the creation of a homosexual identity. Understanding male homosexuality as an evolutionary social construction can help us move beyond the traditionally polarized debate between evolutionary psychologists and social constructionists.
After nearly two decades of rigid adherence to the Soviet model of social and economic development, Hungary initiated a series of reforms in the 1960s that emphasize decentralization and market economic mechanisms. Internal repression and surveillance have diminished concurrently. Shaped by these broader social trends, three explanations of disease causation have successively emerged in Hungary since World War II: social medicine, a lifestyle model, and a psychosocial model. Although each model attempts to offer the best explanation for prevailing patterns of morbidity and mortality, each also reflects an underlying world view and the political priorities that derive from it. Social medicine and the lifestyle model have served largely to consolidate the power of ruling elites. The psychosocial model, on the other hand, has the potential to challenge the social order. The current popularity of the lifestyle model seems rooted in a widespread cynicism about social change which in turn is a product of contemporary social conditions in Hungary.
Disease incidences in human populations depend on etiology of the disease, the fitness of individuals, and demographic changes of the population. The fitness of an individual is determined not only by the disease but also by other factors such as cultural and social reaction to the disorder and demographic changes of the population. Social selection studies the effect of the social behavior on the incidence of a trait. In studies of Huntington's disease, it has been shown that the fitness of the normal sibling of an affected individual is reduced as much as that of the affected individual himself or herself. A similar social effect has been observed for mental retardation. Thus, even if an individual has a normal genotype, mate finding and fertility may be changed considerably by the presence of affected family members. At the present time, the way in which genetic variabilities are maintained is poorly understood even for clearcut genetic diseases. Studies of social selection indicate that such information should be acquired by considering both the nature of the disease and its social effect.
