Many women are initially unable to contract the pelvic floor muscles (PFMs) properly, activating other muscle groups before, or instead of, PFM. Numerous authors have proved that biofeedback can be an ideal tool supporting learning of the PFM contraction. However, there is currently a lack of scientific data on how many biofeedback sessions are necessary in this educational process. In this study we aimed at assessing the effects of one-time electromyography (EMG) biofeedback session on the order in which PFM are (...) activated (so called firing order) during conscious contractions in relation to selected synergistic muscles in pregnant, continent women. A randomized controlled trial was conducted in 90 healthy nulliparous women with uncomplicated pregnancies and without diagnosed urinary incontinence. We divided the participants into a biofeedback group (50) and a control group (40). They were, respectively: 30 ± 4 and 30 ± 4 years old, at their 23 ± 5 or 25 ± 7 week of gestation and presented 23 ± 5 or 24 ± 5 kg/m2 BMI value (M + SD). Surface EMG with vaginal probes has been used to assess the PFM firing order in selected tasks: in five 3-s maximal contractions (quick flicks), five 10-s contractions, and in a 60-s contraction (static hold). We used the 1–5 scale, where “1” meant the best score, awarded when PFM was activated first in order. The most important finding of our study is that a single EMG biofeedback substantially improved the PFM contractions in pregnant women. First, when applying one-time biofeedback session, more women maintained correct technique or improved it in the second assessment, compared to the control group (73 vs. 65%). Secondly, using the quantitative and qualitative analysis with the Chi-square McNamara B/C test, in the biofeedback group we observed a statistically significant improvement of PFM firing order in four tasks: in the first quick flicks (p = 0.016), third quick flicks (p = 0.027), fifth quick flicks (p = 0.008), and in the first 10-s contractions (p = 0.046). In the control group we observed better outcome only in one motor task: in the fourth 10-s contraction (p = 0.009). Given the positive effects of a single session of EMG biofeedback on the firing order in the PFM contractions, it should be recommended for pregnant women without urinary incontinence to teach them how to perform PFM exercises correctly.

This article seeks to examine Rorty's contention that literary narrative, not political philosophy, is best able to address the problems of the West. It argues that although Rorty's conception of the novel as a valu able and informative medium is credible, he does not establish it as a valid alternative to political philosophy. Moreover Rorty retains the sort of reasoning that is characteristic of political philosophy, despite his assertions to the contrary.

The prototypes of definiteness and indefiniteness in English are the definite article the and the indefinite article a/an, and singular noun phrases (NPs)1 determined by them. That being the case it is not to be predicted that the concepts, whatever their content, will extend satisfactorily to other determiners or NP types. However it has become standard to extend these notions. Of the two categories definites have received rather more attention, and more than one researcher has characterized the category of definite (...) NPs by enumerating NP types. Westerståhl (1985), who is concerned only with determiners in the paper cited, gives a very short list: demonstrative NPs, possessive NPs, and definite descriptions. Prince (1992) lists proper names and personal pronouns, as well as NPs with the, a demonstrative, or a possessive NP as determiner. She notes, in addition, that “certain quantifiers (e.g. all, every) have been argued to be definite” (Prince 1992: 299). This list, with the quantifiers added, agrees with that given by Birner & Ward (1998, 114). Ariel (1988, 1990) adds null anaphoric NPs. (shrink)

Aristóteles foi o primeiro pensador que articulou uma taxonomia do conheci-mento científico: os quatros livros dos Segundos Analíticos descrevem os critérios que uma disciplina qualquer deve respeitar e satisfazer para legitimamente receber a designação de ciência teorética. Mas Aristóteles é mesmo o criador das “ciências particulares”, ou seja, a biologia, a psicologia, a zoologia e, em geral, as ciências naturais. Trata-se de uma questão já clássica saber se o modo pelo qual Aristóteles desenvolve sua ciência dos animais con-forma-se aos padrões (...) normativos estipulados pela teoria da ciência nos Analíticos. Na men-talidade de muitos intérpretes ficou a convicção de que as obras biológicas de Aristóteles conformam-se a um padrão que utiliza apenas dados empíricos, ao passo que o conheci-mento nos Analíticos é estabelecido a partir de premissas primeiras e imediatas. Agora, nos Segundos Analíticos, encontramos exemplos provenientes da meteorologia, da botânica, da zoologia ao lado de exemplos matemáticos. Fica a pergunta: a metodologia axiomática de estilo matemático que o Estagirita propõe nos Analíticos é totalmente independente e ina-dequada para o estudo da biologia? Se for assim, Aristóteles não teria conseguido encaixar as ciências naturais nos padrões normativos expostos nos Segundos Analíticos. No presente estudo, pretendemos, pelo contrário, ressaltar o fato de que é razoável tomar os textos aristotélicos como orbitando em torno de uma mesma e grande pesquisa, a pesquisa cientí-fica, que inclui os Analíticos, assim como os tratados naturais.Aristotle was the first Greek thinker to articulate a taxonomy of scientific pursuits: the four books of the Analytics present a theory of scientific knowledge with a rigorous ac-count of what a body of propositions must be like in order to count as a theoretical science. But Aristotle was also the originator of “special sciences”. A longstanding problem about Aristotle’s philosophy of science is to understand if there is a conflict between the account of scientific explanation in the Posterior Analytics and the investigations reported in treatises such as the History of Animals, Parts of Animals, Generation of Animals 1. The Analytics restricts knowledge to what has been demonstrated from self-evident first principles. The sciences of nature seem to secure their results without such demonstrations: there are not axioms, nor theorems or proofs, nor definitions. Yet many of the examples in the Posterior Analytics are drawn from meteorology, botany and zoology, and are discussed side by side with mathe-matical examples. It is curious that a philosopher as systematic as Aristotle could formulate the first rigorous theory of scientific inquiry and demonstration, pepper the treatise in which he does so with biological examples, and not aim to structure his science of animals in ac-cordance with that theory. In this investigation I want to show that there is a relation betwe-en Aristotle’s official account of the definition in Posterior Analytics and the nature and the role assigned to definition in the Natural Treatises.

In this text Cassin and Narcy begin their reassessment of the mode of thought that is sophistry, which has historically functioned as the (negative) “other” of classical philosophy. To this end, the authors first present a close reading of Book Gamma of Aristotle’s Metaphysics, understood as a concerted “strategy against sophism” that, in establishing a logical basis for metaphysics, seeks to relegate the former to the sidelines once and for all. What proves ineliminable in this operation, however, and which “resurfaces (...) beyond metaphysics,” is discourse itself. Cassin and Narcy then set about exploring the contemporary resurgences of sophistry, first through the discourse of (novelistic) fiction, then, more rigorously, in the work of Jacques Lacan, whose own thought poses radical challenges to the relation of language to meaning.

Socio-economic status and mathematical performance seem to be risk factors of mathematics anxiety in both children and adults. However, there is little evidence about how exactly these three constructs are related, especially during early stages of mathematical learning. In the present study, we assessed longitudinal performance in symbolic and non-symbolic basic numerical skills in pre-school and second grade students, as well as MA in second grade students. Participants were 451 children from 12 schools in Chile, which differed in school vulnerability (...) index, an indicator of SES. We tested an explanatory model of MA that included SES and longitudinal performance in basic numerical skills as predictors. The results showed a direct effect of SES on MA and a mediating effect of performance in symbolic and non-symbolic comparison tasks in pre-school. However, in second grade, only performance in symbolic comparison significantly mediated the SES-MA relationship. These findings suggest that performance in non-symbolic comparison plays an important role in explaining MA at initial stages, but that its influence is no longer significant by the time children reach formal instruction in second grade. By contrast, as children’s formal educational experience in mathematics increases, MA becomes linked primarily to symbolic numerical tasks. In sum, SES affects MA and this is due in part to the effect of SES on the development of numerical learning in pre-school, which in turn has an impact on subsequent, more complex learning, ultimately leading to differences in MA. We discuss the implications of these findings for preventing and acting upon the emergence of MA. (shrink)

This article investigates the subject of pilgrimage and change, regarding the pilgrimage to Santiago de Compostela from a pilgrim's perspective. Two aspects of change are being looked at more closely: 1. The inner transformation of today's pilgrims during their pilgrimage, as well as the factors leading to their transformation, and 2. The occurance of recent structural changes of the pilgrimage and their background. These changes also reflect the tensions between pilgrimage and tourism, and the pilgrims and the politics of pilgrimage (...) respectively. (shrink)

This collection breaks new ground in four key areas of feminist social thought: the sex/gender debates; challenges to liberalism/equality; feminist ethics; and feminist perspectives on global ethics and politics in the 21st century. Altogether, the essays provide an innovative look at feminist philosophy while making substantive contributions to current debates in gender theory, ethics, and political thought.

Los conceptos de democracia y de gobierno representativo están inevitablemente conectados y vinculados entre ellos, y uno de los principios fundamentales de la democracia representativa es el principio de mayoría. Este articulo es una aproximación a la teoría de John Stuart Mill sobre el gobierno representativo en relación con el principio de mayoría y bajo su perspectiva elitista. Mill consideró el sistema representativo el modelo político más eficaz, aunque quiso subrayar los puntos críticos y los posibles desvíos negativos de la (...) democracia y, en particular, el riesgo de una dictadura de la mayoría y el contextual aislamiento político de las minorías. El filósofo inglés propuso un ideal de democracia basado sobre el mandato representativo que supone la independencia del representante si bien una independencia restringida y condicionada. Por otra parte, insistió sobre la importancia de que cada ciudadano fuese educado en la conciencia pública y se dejase influenciar por los hombres más cultos y iluminados de la comunidad. (shrink)

This article reports on a replication study of “Childless by choice? Attributions and attitudes concerning family size”, research published in Social Behavior and Personality and carried out by Valerie LaMastro in 2001. In the study presented in this paper the author examined the personality characteristics ascribed by naive perceivers to people with families of varying sizes. Students read one of twenty-four paragraphs describing a heterosexual couple who varied in the number of children they had and in male and female employment (...) status. Targets were rated on 28 personality characteristics and seven relationship quality statements concerning the level of family happiness. The results obtained indicated that a childless pair was viewed as less happy than those with children. Parents of any size family were, however, perceived similarly. (shrink)

In the past few years, there has been growing public awareness of the existence of slavery. This may be attributed in part to the media coverage of the civil war raging in the Sudan which, among other things, has revealed a bustling market in human trafficking. However, little or no attention has been directed to several other regions in the world, including, for example, the Arabian Gulf States, where rapid modernization tends to hide a gruesome reality of modern day slavery. (...) This paper examines three forms of slavery in the United Arab Emirates, used here as a case study—the exploitation of children as camel jockeys; the sexual enslavement of women; and the migrant workers who enslave themselves. By relating the data on present-day slavery to both the history of this ancient institution and to our current definitions of slavery, the author concludes that what is needed is a deeper awareness of the scope, nature, and forms of modern day slavery and a global effort to abolish it.

This paper investigates why women in their first year enter philosophy at a representative level but their participation falls subsequently thereafter. Using data gathered from women students that are currently enrolled in a philosophy department at a university in Aotearoa New Zealand, the paper provides a set of recommendations for changing this pattern in women’s participation and how one particular department responded to these recommendations. In addition, the paper raises several reflective questions concerning the data gathered from women students, including (...) why a number of women describe their experience in the philosophy department as being no different than that of their male counterparts.
