The paper traces the secular trend in stature in Poland in the interwar period. On the basis of individual measuring cards created by military authorities for Krosno and Sarny districts, the author states that the secular trend in stature that started in the mid-1860s continued between the two world wars with the velocity of at least 0.7 cm per decade, i.e. at a similar rate as in the second half of the 19th century. Although regional differences inside the Second Polish Republic were clearly visible, cohorts born during the Great War were able to make up the lost ground in their teens despite the hardships caused by the Great Depression of the 1930s.  相似文献

This contribution questions the positive/negative eugenics dichotomy that typifies the historiography on the eugenic movement in the Netherlands and the claim that this movement was mostly marginal because only positive eugenics was pursued. From 1938 to 1968 in the Netherlands, after a decade of debates, 400 sex offenders who had been committed to asylums for the criminally insane were 'voluntarily' and 'therapeutically' castrated. For political reasons debates on castration, meant to create consensus, eliminated any reference to or connotation with eugenics, yet these policies were unthinkable without them. This article shows that thinking about social and sexual problems and their solutions in the 1930s were permeated by eugenic folklore which in turn was informed by sexual folklore. Both eugenic and sexual lore, as common sense, or as ways of knowing, were about individual and collective loss of self control which was referred to with a catch-all phrase: 'hypersexuality'. Although sexual classifications used in diagnosing sex offenders suggested the existence of discrete sexual categories, homosexuality for instance was not seen as a sexual alternative or as an identity but as the extent to which an offender suffered from a form of hypersexuality that threatened the fabric of society.  相似文献

This essay examines the generative effects of claiming moral failure within a Ukrainian liberal movement for media reform in post-Maidan, pre-invasion Ukraine. The reformers wished to reorganize news reporting around the ideals of autonomy, balanced objectivity, impartiality, and corrigibility, which they believed underpinned Western media. They decried most Ukrainian media as failing such standards, highlighting the individual moral failure of journalists bankrolled by oligarchs in return for favourable media representation. In turn, those from whom the reformers tried to distinguish themselves morally mocked them as ‘grant-eaters’ for their dependence on Western democracy promotion grants. This tussle pitted material success against yearnings for moral and professional probity. Developing Selka's idea of moral distinction, I argue that while the reformers’ pursuit of virtuous difference was sincere, their structural vulnerability vis-à-vis the mainstream media also made morality more salient as the basis for agonistic differentiation.  相似文献

A sexological movement look form in France in the 1930’s on the initiative of the alienist Dr. Edouard Toulouse. The movement combined the approach of mental hygiene with the “biocratic” ideas of this psychiatrist: to rationalise social and sexual life, through science. Even though this movement founded, an association, instigated a scholarly society, produced its own journal and was supported by eminent personalities of the medical, political and cultural worlds, there is very little historical trace of this movement and consequently it is generally unknown. The author of the article explores the reasons for this oversight and analyses the relationships between this movement and some members of the then emerging French psychoanalytical movement, particularly Dr. Paul Schiff and Princess Marie Bonaparte, from the beginning of 1930’s to the war. The author retraces the socio-political factors which underpinned Toulouse’s initiative and the causes of its apparent failure. This particular case also highlights the relationships between contemporary psychiatry, eugenics and psychoanalysis, and more generally between science, popularization and ideology.  相似文献

This article describes the impact of, and response to, Trofim D. Lysenko’s anti-genetics campaign in Poland between the years 1949 and 1956. It focuses particularly upon the response of three individuals – Teodor Marchlewski, Wac?aw Gajewski, and Aleksandra Putrament – who were central figures in the controversy in Poland. In addition to examining the responses and motivations of these individuals, the article also addresses the question of why the Lysenko-era in Poland ended relatively earlier than in neighboring Soviet-allied states such as Hungary, East Germany or Czechoslovakia, as well as 9?years before Lysenko was forced from power in the USSR. I argue that conditions specific to Polish politics and Poland’s relationship with the Soviet Union, during the Thaw after Stalin’s death, provided the opponents of “Lysenkoism” in Poland with an opportunity to criticize Lysenko, and restore Polish genetics. These conditions are linked to the near-revolution in Poland following the strike in Poznan in June, 1956, and successful transition of power between Edward Ochab and W?adys?aw Gomu?ka the following October.  相似文献

Distinguishing mechanisms for the evolution of co-operation   总被引:1,自引:0,他引:1  
The existence of co-operation between species has been cast as a problem to the selfish-gene view of evolution: why does co-operation persist, when it would seem that individual selection should favor the unco-operative individual who exploits the co-operative tendencies of its partner and gives nothing in return? The recent literature has emphasized one type of model as underlying the evolution and stability of interspecific co-operation, which we term the "partner-fidelity" model, and which is typified by the game theory model known as the iterated Prisoner's Dilemma game. Under this mechanism, individuals are associated with the same partner(s) during an indefinite sequence of interactions. Individuals who at any time fail to co-operate with their partner can be penalized by those same partners in subsequent trials, hence the co-operation can be evolutionarily stable. Many examples of biological co-operation that have been offered appear to conform to this model. However, a few examples appear instead to fit a different and unrecognized mechanism, termed "partner-choice". Under partner-choice, individuals are associated for just one interaction, but an asymmetry enables one member to differentially reward co-operative vs. unco-operative partners in advance of any possible exploitation. Possible examples of co-operation maintained through partner-choice mechanisms are provided by the yucca/yucca moth system and the fig/fig wasp system.  相似文献

Developmental patterning requires juxtacrine signaling in order to tightly coordinate the fates of neighboring cells. Recent work has shown that Notch and Delta, the canonical metazoan juxtacrine signaling receptor and ligand, mutually inactivate each other in the same cell. This cis-interaction generates mutually exclusive sending and receiving states in individual cells. It generally remains unclear, however, how this mutual inactivation and the resulting switching behavior can impact developmental patterning circuits. Here we address this question using mathematical modeling in the context of two canonical pattern formation processes: boundary formation and lateral inhibition. For boundary formation, in a model motivated by Drosophila wing vein patterning, we find that mutual inactivation allows sharp boundary formation across a broader range of parameters than models lacking mutual inactivation. This model with mutual inactivation also exhibits robustness to correlated gene expression perturbations. For lateral inhibition, we find that mutual inactivation speeds up patterning dynamics, relieves the need for cooperative regulatory interactions, and expands the range of parameter values that permit pattern formation, compared to canonical models. Furthermore, mutual inactivation enables a simple lateral inhibition circuit architecture which requires only a single downstream regulatory step. Both model systems show how mutual inactivation can facilitate robust fine-grained patterning processes that would be difficult to implement without it, by encoding a difference-promoting feedback within the signaling system itself. Together, these results provide a framework for analysis of more complex Notch-dependent developmental systems.  相似文献

Many species have extreme within-sex morphological and behavioral polymorphisms, most commonly different male phenotypes that practice different reproductive strategies. Although much is known about the role of hormones in sexual differentiation, little is known about what role hormones might play in within-sex differentiation. The relative plasticity hypothesis is derived from the classical organization-activation model of hormone action. It distinguishes between two types of polymorphic systems: a fixed system in which individual males assume one phenotype for their adult lives and a plastic system in which individual males can change phenotypes at least once. By analogy to sexual differentiation, the relative plasticity hypothesis generally predicts that organizational influences of hormones will be more important in fixed systems and activational influences of hormones will be more important in plastic systems. A review of our knowledge of the role of hormones in differentiation of within-sex polymorphisms indicates that the relative plasticity hypothesis accounts for otherwise diverse and contradictory results. This further supports the hypothesis that the organizational-activational model of hormone action derived from sexual differentiation generalizes to within-sex polymorphisms. However, studies of the effects of hormone manipulations on within-sex differentiation are rare but are desperately needed to further our understanding of this problem. Further studies of discontinuous behavioral variation characteristic of polymorphic species may further our understanding of the physiological basis of within-sex behavior variation in all species.  相似文献

The paper argues that the well-known triadic relationship between kin state, resident state and national minority needs to take into account a fourth dimension: that of European institutions. This is illustrated through a study of relational identities on the EU’s Eastern border where the reconfiguration of ethnic relations followed the end of the iron curtain and EU accession. It considers two neighbouring ethnic minorities. One minority is part of the EU – the Belarusians in Poland – and the other is not part of the EU – the Poles in Belarus. The paper argues that the intersection of these four relational dimensions result in contrasting kinds of ethnic identification for the two minority groups leading to either fluidification or solidification under different circumstances.  相似文献

This paper investigates hypotheses drawn from two sources: (1) Belsky, Steinberg, and Draper’s (1991) attachment theory model of the development of reproductive strategies, and (2) recent life history models and comparative data suggesting that environmental risk and uncertainty may be potent determinants of the optimal tradeoff between current and future reproduction. A retrospective, self-report study of 136 American university women aged 19–25 showed that current recollections of early stress (environmental risk and uncertainty) were related to individual differences in adult time preference and adult sexual behavior, and that individual differences in time preference were related to adult attachment organization and sexual behavior. These results are consistent with the hypothesis that perceptions of early stress index environmental risk and uncertainty and mediate the attachment process and the development of reproductive strategies. On this view individual differences in time preference are considered to be part of the attachment theoretical construct of an internal working model, which itself is conceived as an evolved algorithm for the contingent development of alternative reproductive strategies.  相似文献

The dissolution of Soviet-type socialism has been often taken to signal various ends: the end of history, ideology, and revolution; the foreclosure of the symbolic and epistemic space of emancipation opened up by the French, Russian, and anti-colonial revolutions. Yet, the celebrations of the march of liberal democracy and capital have soon given way to alarming observations about a new wave of right-wing populism that feeds on the contradictions of inequality and freedom, largely generated by neoliberal capitalist globalization. Based on my field research in Poland, my paper engages with this familiar problem, which is often discussed as the “crisis” of liberal democracy, or “dedemocratization.” I show how the ends of communism and revolutionary politics have contributed to the social environment of emptiness, nihilism or the void, in which right-wing groups were able to thrive and claim to be the real voice of social change and justice, as opposed to the liberal establishment. To explore the way that void has been historically and materially constituted, my paper traces the shifting conditions of collective action or revolutionary practice in Poland and Eastern Europe since the 1960s. Specifically, I focus on the tragic dissolution and absorption of the massive “Solidarity” worker movement into neoliberal state building in the 1990s and thereby engage with the often-invoked dialectic between insurrection and constitution, or movement and institutionalization that haunt the revolutionary struggles.  相似文献

Two very basic ideas in sexual selection are heavily influenced by numbers of potential mates: the evolution of anisogamy, leading to sex role differentiation, and the frequency dependence of reproductive success that tends to equalize primary sex ratios. However, being explicit about the numbers of potential mates is not typical to most evolutionary theory of sexual selection. Here, we argue that this may prevent us from finding the appropriate ecological equilibria that determine the evolutionary endpoints of selection. We review both theoretical and empirical advances on how population density may influence aspects of mating systems such as intrasexual competition, female choice or resistance, and parental care. Density can have strong effects on selective pressures, whether or not there is phenotypic plasticity in individual strategies with respect to density. Mating skew may either increase or decrease with density, which may be aided or counteracted by changes in female behaviour. Switchpoints between alternative mating strategies can be density dependent, and mate encounter rates may influence mate choice (including mutual mate choice), multiple mating, female resistance to male mating attempts, mate searching, mate guarding, parental care, and the probability of divorce. Considering density-dependent selection may be essential for understanding how populations can persist at all despite sexual conflict, but simple models seem to fail to predict the diversity of observed responses in nature. This highlights the importance of considering the interaction between mating systems and population dynamics, and we strongly encourage further work in this area.  相似文献

The question posed by the title is usually answered by saying that the "synthesis" between the theory of evolution by natural selection and classical genetics, which took place in 1930s-40s, would have taken place much earlier if Darwin had been aware of Mendel and his work. What is more, it nearly happened: it would have been enough if Darwin had cut the pages of the offprint of Mendel's work that was in his library and read them! Or, if Mendel had come across Darwin in London or paid him a visit at his house in the outskirts! (on occasion of Mendel's trip in 1862 to that city). The aim of the present paper is to provide elements for quite a different answer, based on further historical evidence, especially on Mendel's works, some of which mention Darwins's studies.  相似文献

This article aims to analyse a possible manner of approaching the birth of intersexual children. We start out by summing up what intersexuality is and how it is faced in the dominant clinical practice (the “treatment paradigm”). We then argue against this paradigm, in favour of a postponement of genital surgery. In the second part of this paper, we take into consideration the general question of whether only two existing sexes are to be recognized, arguing in favour of an expansion of sex categories. In the third part, we illustrate the reasons supporting provisional sex attribution: the child’s best interest and respect for their developing moral autonomy. This position aims to increase the child’s well-being and self-determination, limiting parents’ freedom to take decisions on behalf of others, in particular, those decisions concerning basic aspects of their children’s personal identity.  相似文献

The way from scientific finding through invention to production line and finally to the consument is long and expensive and patent should be taken into account. This is evident because the investment connected with the new application needs clear definition of intellectual property rights. Independently what we personally think about patenting in nature sciences--this is a common practice around the world. The positive and negative parameters of patenting are focus on biotechnology. The development of biotechnology is a cumulative effect of co-operation of several disciplines: biology, biochemistry, chemistry, engineering, genetics, medicines and pharmacy and many more. Between not cited here is law and consequently the needs of cooperation between researchers and lawyers. There are several barriers in this co-operation, for example: nomenclature as well as the way of thinking. These borders could be pass only with intercommunication and cross-understanding. The dialog and transfer of knowledge is a must for understanding the nomenclature, terminology of nature by lawyers and by researchers in case of law. Polish legislation concerning intellectually rights is regulated by the law "Prawo w?asno?ci przemys?owej" (30 June, 2000; Dz. U. 2003, Nr 119, pos. 1117, with later amendments). This legislation is related to European Union directives and Munich Convention. Accordingly patenting of product and process is possible in Poland. However, the procedure is time and money consuming, particularly in the case of patent submission in several countries. Amendment of the Polish law to biotechnology made possible patenting of living organism and their parts. It is worth to stress that patented inventions can be used free of charge for research and teaching.  相似文献

On December 17, 2003, French President Jaques Chirac went on television to explain the immediate necessity of passing a law recently proposed by the Stasi commission. This commission had been empowered to explore the failures of the last thirty years of French immigration policy in terms of integration. It had also been specifically instructed to investigate threats to the concept of laicite, the rigorous French version of secularism and the separation of the Church and the State. Chirac explained that, following the commission’s advice as well as that of numerous experts, he had centered on a policy to deal with these issues: We shall do so by bringing to life the principle of secularism, which is a pillar of our constitution. It expresses our wish to live together in respect, dialogue and tolerance. Secularism guarantees freedom of conscience. It protects the freedom to believe or not to believe. He then expanded upon what this freedom requires: It is the neutrality of the public sphere which enables the harmonious existence side by side of different religions. Like all freedoms, the freedom to express one’s faith can only have limits in the freedom of others, and in the compliance with rules of life in society. Religious freedom, which our country respects and protects, must not be abused, it must not call general rules into question, and it must not infringe the freedom of belief of others. Finally, Chirac, building to a rhetorical climax, came to the essence of the new law which had provoked so much commentary around the world: In all conscience, it is my view that the wearing of clothes or of symbols which conspicuously demonstrate religious affiliations must be banned in state schools. The hypothesis which I wish to advance is that in the actual world in which we inhabit the language of morality is in the same state of grave disorder as the language of natural science is in the imaginary world which I described. What we possess are the fragments of a conceptual scheme... we posses indeed simulacra of morality... but we have lost our comprehension, both theoretical and practical, of morality.  相似文献

Direct sexual selection via mutual mate choice can result in both sexes showing conspicuous traits. We experimentally tested whether this hypothesis can explain tail length in the bearded tit (Panurus biarmicus). In this species, both sexes have a long, graduated tail. Males have, however, a longer tail than females, suggesting perhaps that females are choosier than males in selecting mates. We used two choice set‐ups for each sex: shortened vs. control tail individuals and elongated vs. control tail individuals. We found that direct sexual selection seems to operate differently in the two sexes. In both set‐ups, females spent more time with the male with the longest tail, and they also showed sexual display behaviour only towards these males. Males spent more time with control than with short‐tailed females, but they did not discriminate between control and long‐tailed females. Moreover, males displayed preference towards both short‐ and long‐tailed females. Thus, females preferred long‐tailed males, whereas males did not always prefer long‐tailed females. Our study suggests that mutual mate choice has played a role in the evolution of long tails in bearded tits. It also suggests that the sexual dimorphism in tail length has evolved because mate choice exerts a stronger sexual selection pressure on males than on females.  相似文献

Today''s emphasis on youth makes it increasingly difficult to accept growing old. The denial of ageing is reflected in society''s attitudes and in the paucity of medical and psychiatric literature on the subject. In the middle years there is the greatest demand for adequate emotional adaptation during a rapidly changing period in life, which frequently involves two people, both separately and together. This paper discusses some of the problems which may be encountered from the psychosomatic, sexual and psychological aspects in the middle-aged man, woman and the couple. It emphasizes the need for the family physician to be aware of these difficulties and to be able to help the patient deal with them. The more successful the resolution of the middle-age crisis, the more contented and peaceful will be the acceptance of old age by the individual.  相似文献
