Sociolinguistic variability in oral narrative.

This thesis begins with a sociolinguistic correlational study of three phonetic variables - (h), (t) and (ing) - as used by four occupational groups - nurses, chefs, hairdressers and taxi-drivers. The groups were selected to incorporate three independent variables: sex (male-dominated versus female-dominated occupations); training (length and specialisation - nurses and chefs being more specialised than hairdressers and taxi-drivers) and location (the populations were selected from two cities - Liverpool and Birmingham). Although the correlational work demonstrates intra-sex and occupation consistency in speakers' choice of linguistic variants (females (particularly nurses) being significantly closer to the prestige norm), it is essentially non-explanatory and cannot accout for narrative dynamics and style shift. Therefore, an in-depth qualitative examination of the data (which draws mainly on Narrative and Discourse Analysis) forms the major part of the analysis. The study first analyses features common to all the narratives, direct speech, expressive phonology and linguistic ambiguity emerging as characteristic of all humorous storytelling. Secondly, three major sources of inter-personal variation are invetigated: narrator perspective, sex and occuptational role. Perspective is found to vary with topic and personality, greater narrator involvement coinciding with a higher proportion of internal evaluation devices. Sex differences include topic choice and bonding in the storytelling sessions. Sex differences are also evident in style shifting, where the narrator mimics the voice of a character in the narrative (aodpting segmental and/or prosodic tokens to signal a change of persona). The research finds that female narrators rarely employ segmental accommodation downwards on the social scale (whereas men do), but are on the other hand adept at using prosodic effects for mimicry. Taxi-drivers emerge as the group with the most distinctive narrative flair, a fact which is related to their occupation. The conclusion stresses a need for both quantitative and qualitative approaches to data; the importance of occupational role, as opposed to sex role per se in determining narrative conventions; the view of narrative as a negotiable entity, which is the product of relationships among participants; and the importance of considering the totality of the communicative act.

A családi fészekben élő fiatal felnőttek és fogyasztói döntéseik (In the family nest living young adults and their consumer decisions)

Fiatal felnőttek nagyarányú jelenléte a szülői háztartásokban nemcsak Magyarországon és Európában jellemző, de a fejlett ipari országokban általánosan megfigyelhető jelenség. Az Európai Unióban élő 18–34 év közötti fiatalok 46%-a él együtt legalább egyik szülőjével, a magyar fiatalok esetében hasonló az arány. A fiatalok kitolódó felnőtté válása azt is jelenti, hogy a szülők egyre későbbi időponttól kezdve rendelkeznek szabadabban idejükkel és anyagi forrásaikkal, a fiatal felnőttek döntései pedig részben szüleik részvételével történik. Jelen cikk arra keresi a választ, hogy a szülői fészekben élő vagy a szüleiktől részben függő fiatalok milyen döntési mintákkal rendelkeznek, illetve vásárlási döntéseikben mennyire önállóak. A kérdés vizsgálatát a szülői háztól függő egyetemista fiatalok körében végzett kérdőíves megkérdezés segítségével a szerzők elemezték, és arra is lehetőségük volt, hogy a családtagok által írt rövid esszék segítségével a kérdést több oldalról vizsgálják meg. Eredményeik szerint a szülői háztól függő fiatal felnőttek önálló döntésre képes, sok esetben szakértő fogyasztók, döntéseik önállóságát azonban a termékkategória, a családdal való kapcsolattartás gyakorisága, a családforma és a nemi szerepek is befolyásolják. ____ High ratio of adult children is still living in their parents’ home. This is a significant phenomenon that can be observed in Hungary and throughout Europe, while influences living trends globally. In the EU, 46% of youth between 18-34 years live with at least one of their parents and this same statistic holds true in the case of Hungary. This postponement of adulthood allows parents to enjoy more free time and have higher disposable income from later in life. The young adults, however, in the household make their consumer decisions under parental control. The purpose of this study is to explore the decisionmaking styles of young adults and their independence from their parents in shopping-related decision-making through a literature review and primary study. The survey focused on university students who are dependent on their parental home and short essays were also collected from family members of the target group in order to gain a more complex view on this phenomenon. According to the results the following conclusion can be made: young adults living in their parents’ home are competent consumers with individual decisions, in addition, they are consumer experts within the family in many cases. However, their independent shopping-related decision-making is influenced by product category, frequency of connection to the family home, family form and also sex role orientations.

The effect of sexist attitudes on the perception of visual artists by community college and university students

This study compared the effects of sexist labeling on the perceptions of visual artists by the community college and university students and determined their sex role orientation. The 370 students were shown five slides of an artist's works and were given six versions of an artist's biography. It contained embedded sexual labeling (woman, girl, person/ she, man, guy, person/he). The Artist Evaluation Questionnaire was administered to the female and male community college and university students that required the students to evaluate the female and male artists on several aspects of affective and cognitive measures. The questionnaire consisted of 9 items that had to be rated by the participants. In addition, the students filled out the Demographic Questionnaire and the BEM Sex Role Inventory, titled the Attitude Questionnaire. The Analysis of Variance testing procedures were administered to analyze the responses. The results disclosed gender differences in students' ratings. The female artist's work, when the artist was referred to by the neutral sexual label, "person", received significantly higher ratings from the female students. The male students gave the female artist her highest ratings when she was referred to by the low status sexual label, "girl". Both sexes did not express statistically significant preferences for any of the male sexual labels. Gender difference became apparent when it was found that female students rated both sexes equally, and their ratings were lower than those of the male students. The male students rated the female artist's work higher than the work of the male artist. The analysis of the sex role inventory questionnaire revealed the absence of the feminine (expressive) and masculine (instrumental) personalities among the students. The personalities of almost all the students were androgynous, with a few within the range of the near feminine, and a few within the range of the near masculine. The study reveals that there are differences in perception of sexual labels among the community college and university students.

Gleichermaßen auf das Leben vorbereitet? Ergebnisse der Jugendstudie AIDA

In [diesem] Beitrag stellen die Autoren ausgewählte Ergebnisse der Berliner Längsschnittstudie AIDA (Adaptation in der Adoleszenz) vor und knüpfen dabei an die Frage "Equally prepared for life?" an, die die OECD (2009) im Rahmen einer Re-Analyse von PISA-Daten stellte und mit Blick auf die Leistungsunterschiede in Mathematik und Naturwissenschaften mit einem "Nein" beantwortet wurde. Denn: Weibliche Jugendliche berichten über mehr Angst im Fach Mathematik, haben weniger Selbstvertrauen, spezifische mathematische Probleme lösen zu können, und neigen dazu, ihre Leistungsfähigkeit zu unterschätzen. Der internationale Vergleich verdeutlicht, dass diese Geschlechterunterschiede in Deutschland größer sind als in den meisten OECD-Ländern. Die AIDA-Studie erlaubt es, auch in weiteren nichtkognitiven Persönlichkeitsmerkmalen nach bedeutsamen Unterschieden zu fragen. (DIPF/Orig.)

Genetic evidence for polygynandry in the black-striped pipefish syngnathus abaster: a microsatellite-based parentage analysis

Sexual selection theory predicts that, in organisms with reversed sex roles, more polyandrous species exhibit higher levels of sexual dimorphism. In the family Syngnathidae (pipefish, seahorses, and seadragons), males provide all parental care by carrying developing embryos on their ventral surfaces, and females develop secondary sex characters. Syngnathids exhibit a variety of genetic mating patterns, making them an ideal group to test predictions of sexual selection theory. Here, we describe the mating system of the black-striped pipefish Syngnathus abaster, using 4 highly variable microsatellites to analyze parentage of 102 embryos. Results revealed that 1) both sexes mate multiple times over the course of a pregnancy (polygynandrous mating system), 2) eggs are spatially segregated by maternity within each brood pouch, and 3) larger females have higher mating success (Kolmogorov–Smirnov test; P < 0.05). Together with similar studies of other syngnathid species, our results support the hypothesis that the mating system is related to the intensity of sexual dimorphism.

Sex hormone regulation of innate immunity in the female reproductive tract : the role of epithelial cells in balancing reproductive potential with protection against sexually transmitted pathogens

The immune system in the female reproductive tract (FRT) does not mount an attack against HIV or other sexually transmitted infections (STI) with a single endogenously produced microbicide or with a single arm of the immune system. Instead, the body deploys dozens of innate antimicrobials to the secretions of the female reproductive tract. Working together, these antimicrobials along with mucosal antibodies attack many different viral, bacterial and fungal targets. Within the FRT, the unique challenges of protection against sexually transmitted pathogens coupled with the need to sustain the development of an allogeneic fetus have evolved in such a way that sex hormones precisely regulate immune function to accomplish both tasks. The studies presented in this review demonstrate that estradiol and progesterone secreted during the menstrual cycle act both directly and indirectly on epithelial cells and other immune cells in the reproductive tract to modify immune function in a way that is unique to specific sites throughout the FRT. As presented in this review, studies from our laboratory and others demonstrate that the innate immune response is under hormonal control, varies with the stage of the menstrual cycle, and as such is suppressed at mid-cycle to optimize conditions for successful fertilization and pregnancy. In doing so, a window of STI vulnerability is created during which potential pathogens including HIV enter the reproductive tract to infect host targets.

Proposed role of w chromosome inactivation and the absence of dosage compensation in avian sex determination

Three features of avian sex chromosomes - female heterogamety (ZZ male, ZW female), the apparently inactive state of the W chromosome, and dose-dependent expression of Z-linked genes - are examined in regard to their possible relation to sex determination. It is proposed that the W chromosome is facultatively heterochromatic and that the Z and W chromosomes carry one or more homologous sex-determination genes. The absence of dosage compensation in ZZ embryos, and W inactivation in ZW embryos, would then bring about a 2n(ZZ)-n(ZW) inequality in the effective copy number of such genes. The absence of dosage compensation of Z-linked genes in ZZ embryos is viewed as a means by which two copies of Z-W homologous sex determination genes are kept active to meet the requirements of testis determination. W inactivation may promote ovarian development by reducing the effective copy number of these genes from 2n to n. If there is a W-specific gene for femaleness, spread of heterochromatization to this gene in cells forming the right gonadal primordium may explain the latter's normally undifferentiated state; reversal of heterochromatization may similarly explain the development of the right gonad into a testis following left ovariectomy.

Circulating immunoglobulin A- and immunoglobulin G-secreting hybridoma cells in peripheral blood preferably migrate to female genital tracts. The role of sex hormones

Antigen-specific circulating immunoglobulin-secreting cells (ISC) migrate to various secondary and tertiary lymphoid tissues. To understand the migration of the cells into the genital tract and its regulation by sex hormones, spleen-derived SG2 hybridoma cells secreting immunoglobulin G2b (IgG2b) and Peyer's patch-derived PA4 hybridoma cells secreting polymer IgA were labelled with (3) H-TdR, and intravenously injected into syngeneic mice of both sexes. Using flow cytometry, surface molecular markers of plasma cells, CD38 and CD138, and adhesion molecules, CD49d, CD162, and CD11a were found to be positive in SG2 and PA4 cells, but CD62L, alpha4beta7 and CD44 were not expressed on these cells. The relative distribution indexes (RDIs) of the cells in genital tract and other tissues were measured. The means of RDIs of SG2 and PA4 cells in female genital tissues were 6.5 and 4.5 times as many as the means in male genital tissues, respectively. The treatment of ovariectomized mice with beta-oestradiol significantly increased the RDIs of PA4 cells in cervix and vagina, but decreased the RDIs of SG2 cells in vagina, horn of uterus, uterus and rectum (P <0.05). Progesterone treatment increased the RDIs of PA4 cells in vagina and rectum (P <0.05). The treatment with testosterone significantly increased the RDIs of SG2 and PA4 cells in epididymis and accessory sex glands (P <0.05). These results demonstrate that the female genital tract is the preferable site for the migration of circulating hybridoma cells to the male genital tract, and sex hormones play an important role in regulation of the migration of circulating ISC to genital tracts.

Unmasking a role for sex chromosomes in gene silencing.

Several sexually dimorphic phenotypes correlate with sex-chromosome dosage rather than with phenotypic sex. New research suggests that sex chromosome dimorphism helps to regulate gene silencing.

Sex-related invariance across cultures in an online role-playing game

This study examines the Social Dominance Orientation of players of the online roleplaying game World of Warcraft. The World of Warcraft offers an opportunity to investigate social dominance and biological sex differences in an environment where there is no cultural dominance of one sex over another. Social Dominance Orientation has been found to be different between males and females, with males scoring higher. However, this might be the consequence of social context. To this end sex differences between male and female players were investigated in the World of Warcraft environment, as well as the effects of chosen character sex. Player sex and character sex were found to have effects on Social Dominance Orientation. These results add further support to claims that Social Dominance Orientation has the characteristics of a sexually selected disposition to acquire resources and out-compete rival groups.

Persistent unequal sex ratio in a population of grayling (salmonidae) and possible role of temperature increase.

In some fishes, water chemistry or temperature affects sex determination or creates sex-specific selection pressures. The resulting population sex ratios are hard to predict from laboratory studies if the environmental triggers interact with other factors, whereas in field studies, singular observations of unusual sex ratios may be particularly prone to selective reporting. Long-term monitoring largely avoids these problems. We studied a population of grayling (Thymallus thymallus) in Lake Thun, Switzerland, that has been monitored since 1948. Samples of spawning fish have been caught about 3 times/week around spawning season, and water temperature at the spawning site has been continuously recorded since 1970. We used scale samples collected in different years to determine the average age of spawners (for life-stage specific analyses) and to identify the cohort born in 2003 (an extraordinarily warm year). Recent tissue samples were genotyped on microsatellite markers to test for genetic bottlenecks in the past and to estimate the genetically effective population size (N(e) ). Operational sex ratios changed from approximately 65% males before 1993 to approximately 85% males from 1993 to 2011. Sex ratios correlated with the water temperatures the fish experienced in their first year of life. Sex ratios were best explained by the average temperature juvenile fish experienced during their first summer. Grayling abundance is declining, but we found no evidence of a strong genetic bottleneck that would explain the apparent lack of evolutionary response to the unequal sex ratio. Results of other studies show no evidence of endocrine disruptors in the study area. Our findings suggest temperature affects population sex ratio and thereby contributes to population decline.

The contrasting role of heterochromatin in the differentiation of sex chromosomes: an overview from Neotropical fishes

During the evolutionary process of the sex chromosomes, a general principle that arises is that cessation or a partial restriction of recombination between the sex chromosome pair is necessary. Data from phylogenetically distinct organisms reveal that this phenomenon is frequently associated with the accumulation of heterochromatin in the sex chromosomes. Fish species emerge as excellent models to study this phenomenon because they have much younger sex chromosomes compared to higher vertebrates and many other organisms making it possible to follow their steps of differentiation. In several Neotropical fish species, the heterochromatinization, accompanied by amplification of tandem repeats, represents an important step in the morphological differentiation of simple sex chromosome systems, especially in the ZZ/ZW sex systems. In contrast, multiple sex chromosome systems have no additional increase of heterochromatin in the chromosomes. Thus, the initial stage of differentiation of the multiple sex chromosome systems seems to be associated with proper chromosomal rearrangements, whereas the simple sex chromosome systems have an accumulation of heterochromatin. In this review, attention has been drawn to this contrasting role of heterochromatin in the differentiation of simple and multiple sex chromosomes of Neotropical fishes, highlighting their surprising evolutionary dynamism.
