  6. Son, Sent, and Servant

    Directory of Open Access Journals (Sweden)

    Truls Åkerlund

    2015-11-01

    Full Text Available This study challenges the claim that Jesus is the archetypical servant leader as described in contempo-rary leadership literature. Based on a theological reading of the Fourth Gospel, the paper suggests that, as a servant, Jesus cannot be understood apart from his mission and obedience to God. Consequently, Jesus was not primarily a servant leader but rather the Son who was sent to the world to enact the Fa-ther’s will. In this regard, the Fourth Gospel provides a unique perspective that is barely noted in the current discourse on servant leadership modelled on the example of Christ. Although certain aspects of servant leadership theory correspond to John’s portrayal of Jesus, the study concludes that other de-scriptions of him as a servant leader suffer from a one-sided and reductionist Christology. Implications of this view for Christian ministry are briefly sketched out.

  11. Sons and daughters in China.

    1985-11-01

    Demographers from the East-West Population Institute (EWPI) and the China State Family Planning Commission, jointly analyzing data from computer tapes of China's 1982 national fertility survey, have produced new evidence of the extent to which families in China prefer male children. Evidence exists in almost every part of China that couples prefer sons to daughters, according to researchers Fred Arnold and Liu Zhaoxiang. Only Beijing and Shanghai are exceptions to this pattern. The persistence of such attidues in China demonstrates the difficulty of overcoming deeply rooted Confucian traditions. Following the Chinese revolution, the government guaranteed sexual equality in political, economic, and cultural life, but patriarchal attitudes still prevail, particularly in the countryside. Historically, couples have favored sons for a variety of reasons, including to continue the family name, provide security for the parents' old age, add to the family labor force, and perform ancestral rites. Believing that such attitudes block successful implementation of China's 1-child family policy, the government has launched a campaign to try to change them. At the time of the time of the 1982 fertility survey, China's 1-child certificate program had been in effect for 3 years. The program provides incentives such as monetary bonuses, preferential housing allocation, and special consideration for the child in education and job assignments to couples who agree not to have a 2nd child. According to the survey, 37% of all 1-child couples had accepted the 1-child certificate. Significantly, 60% of all 1-child certificate holders have a son. Of couples whose 1st child was a boy, 40% obtained the 1-child certificate, versus only 34% of those whose 1st child was a girl. Despite penalties for renouncing the 1-child certificate, about 1 out of every 10 mothers in the program had given birth to a 2nd child by the time of the survey. The 1st child of these mothers was twice as likely to be

    Full Text Available La población de la región Huasteca es partícipe de manifestaciones musicales en diferentes ámbitos, lo cual permite reconocer que entre todos los géneros utilizados destaca el son huasteco y su correspondiente bailable llamado huapango. Dichas expresiones musicales se impregnan de los ambientes tanto físico como social que viven constantemente. Es a través de las letras de los sones huastecos que se desarrolla el mecanismo para reflejar el mundo natural que perciben, y los acontecimientos que les suceden, cobrando una importancia que deriva en una identificación que trasciende. Conciben su entorno y lo refieren con sentido de pertenencia-apropiación, que les permite recrear su vida y fundirse en una identificación cultural a la que se le llamará “identidad regional”. La relevancia de considerar una expresión musical de estas características radica en que se preserva y enriquece constantemente unificando un área de México que no necesariamente corresponde a límites políticos establecidos en las diferentes etapas históricas.

    1998-06-01

    In-depth interviews with 30 sons actively involved in caring for a parent with dementia expand the understanding of sons' caregiving experiences. The within-group analysis revealed common themes that emerged from the narratives--duty, acceptance, taking charge, common emotions, and work flexibility--as well as common issues--loss, sibling relationships, role reversal, coping strategies, and positive outcomes. The interviews also generated a typology of son caregivers that included such types as the dutiful son, the son who goes the extra mile, the strategic planner, and the son who shares the care.

  19. Do parents prefer sons in North Korea?

    Science.gov (United States)

    Goodkind, D

    1999-09-01

    Son preference in South Korea is stronger than anywhere else in the world, yet little is known about such preference in North Korea. Simple indicators of son preference in North Korea are constructed from its 1993 population census and a 1998 survey of child nutrition (conducted in the wake of the recent famine). These indicators include sex ratio at birth, sex ratios of infant and child mortality, and sex ratios of child malnutrition. North Koreans do not evince prenatal discrimination against daughters, a finding that may indicate a lack of prenatal sex-testing technologies. Neither is evidence found of excess female mortality or malnutrition in the postnatal period, during which discrimination requires no special technology. The discrepancy in son preference across the Korean peninsula seems due largely to the socialist agenda pursued in the north following political partition after World War II. An important aspect of that agenda challenged the ancient Confucian ideology presumed to underlie son preference. Apparently, this challenge was more successful in North Korea than in other Asian societies instituting similar political changes, because son preference was not eliminated in China or in Vietnam.

    Full Text Available Los cuidados invisibles son un elemento central y fundamental de la práctica de la Enfermería y son la base de su identidad profesional. La Enfermería ha sufrido un importante y positivo proceso de profesionalización en los últimos 150 años, sin embargo, los cuidados invisibles siguen siendo poco reconocidos, a pesar de su importancia en la recuperación y en la calidad de vida de los usuarios. En este trabajo se analizan brevemente las grandes transformaciones sociales actuales que obligan a replantearse la necesidad de visibilizar los cuidados invisibles, se plantean interrogantes clave para abordar esta discusión y se proponen una serie de acciones concretas para avanzar en este reconocimiento.

  2. Communicative competence in sons of alcoholics.

    Science.gov (United States)

    Carter, C; Nochajski, T H; Leonard, K E; Blane, H T

    1990-09-01

    Sons of alcoholic (SA), depressive (SD), and social drinking (SN) fathers gave 3-min speeches under low- and high-stress conditions. Trained raters, unaware of group membership, scored each speech on a variety of communicative competence dimensions. The results gave evidence that the SA group, relative to the SN group, showed deficits in all six speech variables. Further results suggested that the SA group was unaffected by level of stress, while the SD group showed a decrease in communicative clarity from speech 1 (low stress) to speech 2 (high stress). The results suggest lower levels of communicative competence among adult sons of alcoholics. The implication of this finding with regard to the psychosocial functioning of children of alcoholics is discussed.

    Full Text Available Una alta proporción de organizaciones hoy son multiculturales. No solamente porque trabajan en países o ambientes donde se mezclan muchas culturas, sino porque están expuestas a una serie de valores y de prácticas diversos. Las características anteriores nos obligan a pensar en la manera como estas nuevas organizaciones desarrollan su cultura y sus prácticas. Según lo afirma Hofstede, al contrario que las culturas nacionales, las culturas corporativas no son una cuestión de valores compartidos sino de prácticas comunes., por lo que se hace necesario abordar las prácticas corporativas para así conocer y resolver las diferencias.

    2013-01-01

    Full Text Available 'My Son 22.10.11' was made immediately following a miscarriage 8 weeks into pregnancy. After bleeding lightly for a couple of hours, I went to the toilet and a large bloody mass fell from within me. I knew that I could not flush this away, and that to retrieve the mass was my only chance to connect with the unborn foetus. I fished the contents from the bottom of the toilet bowl using my hands and carried them into my small studio. I found some paper and began to dissect the mass. At the centre, I found the tiny, cold, hard foetus. I kissed it and then began to use it as a kind of painting tool, drawing the outline of the lost child using its very own flesh and blood. I knew that to create a lasting and tangible portrait of 'my son' was the best way to understand the somewhat unreal and fleeting experience of miscarriage. I thought of Frida Kahlo while making the work, thinking 'thank God' that I had a reference to miscarriage before it happened to me. I also thought of my childhood days spent on our family pig farm, and of all the dead pig foetuses that I had seen at various stages of development. Before the miscarriage, I thought little about the subject; afterwards, I recognise the profundity of the creation of a life that is never born. The experience is so common, yet so very rarely discussed or depicted.

    Full Text Available In this article I review the publishing and stage trajectory of one of Rojas Zorrilla’s most significant plays: Lo que son mujeres. As well as collecting a list of the different editions, I emphasize the 1822 version by the Mexican Manuel Eduardo de Gorostiza, which started a new renaissance period for this play on stage. I also analyze the 1899 one-act version by Emilio Bobadilla. Finally, I include all the different productions between the 17th and the 19th centuries, and address the little interest aroused in the 20th century–suffice to say that it has not been staged even during these early years of the 21st century when the centenary of Rojas Zorrilla is being celebrated.En este artículo se hace un repaso detallado de la fortuna editorial y escénica de una de las obras más significativas de Rojas Zorrilla: Lo que son mujeres. Aparte de recoger las diferentes ediciones de la misma, se hace hincapié en la refundición del mexicano Manuel Eduardo de Gorostiza, estrenada en 1822, que abrió un período de cierta recuperación de este texto dramático en los escenarios. Se analiza también la refundición que llevó a cabo en un solo acto Emilio Bobadilla en 1899. Finalmente, se registran todas las representaciones conocidas de la obra desde el siglo XVII hasta el siglo XIX y se constata el poco interés que ha despertado en los escenarios del siglo XX. Incluso en los últimos años, en los que los montajes de obras de Rojas comienzan a ser más frecuentes, esta obra no ha sido todavía llevada a escena.

OBJETIVO: propor uma revisão da literatura pertinente às características acústicas, fonéticas e fonológicas dos fonemas fricativos surdos que integram o sistema fonológico do Português. Além disso, são descritas suas aplicações na terapia vocal. CONCLUSÕES: os fricativos são fonemas agudos, abrangendo de 2500 a 8000Hz; são plenamente adquiridos até os 3:7 anos de idade; o /s/ que também é o mais afetado em casos de frênulo lingual curto; a omissão do /s/ é uma das ocorrências mais freqüentes na alfabetização; sendo que, no desvio fonológico e na fissura lábio-palatina, freqüentemente ocorre comprometimento de toda a classe de fricativos. Na avaliação de voz, os fricativos são mencionados com as medidas de TMF e relação s/z, bem como seu uso como sons de apoio na fonoterapia.BACKGROUND: characteristics of voiceless fricative sounds PURPOSE: to review the literature related to acoustic, phonetics and phonological characteristics of voiceless fricative sounds that are part of the phonological system of the Portuguese Language. Furthermore, it describes the use of these sounds in voice therapy. CONCLUSIONS: fricatives are acute phonemes comprised between 2500 and 8000 Hz; they are fully acquired up to the age of 3:7 years; the /s/, which is the most affected in cases of short lingual frenum; omission of the /s/ is one of the most frequent occurrences during literacy education; and in the phonological deviation and labial-palatine fissure the entire class of fricatives is frequently affected. In voice assessment, fricative sounds are mentioned as TMF measurements and s/z relationship, and their use as support sounds in speech therapy.

  10. Mate-sampling costs and sexy sons.

    Science.gov (United States)

    Kokko, H; Booksmythe, I; Jennions, M D

    2015-01-01

    Costly female mating preferences for purely Fisherian male traits (i.e. sexual ornaments that are genetically uncorrelated with inherent viability) are not expected to persist at equilibrium. The indirect benefit of producing 'sexy sons' (Fisher process) disappears: in some models, the male trait becomes fixed; in others, a range of male trait values persist, but a larger trait confers no net fitness advantage because it lowers survival. Insufficient indirect selection to counter the direct cost of producing fewer offspring means that preferences are lost. The only well-cited exception assumes biased mutation on male traits. The above findings generally assume constant direct selection against female preferences (i.e. fixed costs). We show that if mate-sampling costs are instead derived based on an explicit account of how females acquire mates, an initially costly mating preference can coevolve with a male trait so that both persist in the presence or absence of biased mutation. Our models predict that empirically detecting selection at equilibrium will be difficult, even if selection was responsible for the location of the current equilibrium. In general, it appears useful to integrate mate sampling theory with models of genetic consequences of mating preferences: being explicit about the process by which individuals select mates can alter equilibria. © 2014 European Society For Evolutionary Biology.

    2017-04-01

    Full Text Available El texto trata de establecer una relación entre pintura y arquitectura dentro del espacio arquitectónico. El escrito entabla vínculos entre el programa de taller en el edificio proyectado por Josep Lluís Sert y la actividad de pintar de Joan Miró en el estudio de Son Abrines y Son Boter en Mallorca. Uno de los motivos por los que la pintura occidental se conforma por si misma, desde Giotto hasta Picasso por ejemplo, son las relaciones entre espacio y uso que el propio lienzo muestra. Cualquier pintura de la época trata de presentar el misterio de un acontecimiento mediante el contenido pictórico. Son estas relaciones el motivo que muchas veces llevaba al pintor a desarrollar un cuadro. En el caso del estudio proyectado por Sert para Miró, la investigación trata de conjugar espacio de trabajo y espacio de la pintura desde una interpretación a la pintura sin abandonar el espacio en la que es gestada. El fin es revelar o mostrar interpretaciones sobre dos programas característicos del siglo XX: vivienda y taller de pintura; desde un análisis concreto entorno a Joan Miró y Josep Lluís Sert.

    Study 1 compared the retrospectively reported father-son relationships of four groups of adult males: (a) Gynephiles (males who erotically prefer physically mature females), (b) androphiles (who prefer physically mature males), (c) a combined group of heterosexual pedophiles and pedohebephiles (the latter being attracted to pubescent as well as prepubescent females), and (d) a combined group of homosexual pedophiles and pedohebephiles (the latter attracted to pubescent as well as prepubescent males). The gynephiles were paid volunteers; the latter three groups were patients. The androphiles, the only group among those compared known to exhibit a measurably greater degree of cross gender identity in childhood, were also the only group to report significantly poorer father-son relations. The homosexual pedo/pedohebephiles, who also prefer male partners but who exhibit typical male gender identity in childhood, did not differ in father-son relations from the gynephiles or the heterosexual pedo/pedohebephiles. Study 2 showed that, within a sample of nonpatient volunteer androphiles, those individuals who reported the greatest degree of cross gender behavior in childhood also tended to report the worst relationships with their fathers. This correlation was replicated within a sample of androphilic patients in Study 3. The consistent pattern of results obtained from these three studies suggests that the emotionally distant relationships of fathers and androphilic sons relate to the sons' atypical childhood gender identity (or observable gender role behavior) rather than to the sons' erotic preference for male partners per se.

  17. A test of the "sexy son" hypothesis: sons of polygynous collared flycatchers do not inherit their fathers' mating status.

    Science.gov (United States)

    Gustafsson, Lars; Qvarnström, Anna

    2006-02-01

    According to the original "sexy son" hypothesis, a female may benefit from pairing with an already-mated male despite a reduction in fecundity because her sons inherit their father's attractiveness. We used data from a long-term study of collared flycatchers (Ficedula albicollis) collected during 24 years to test this prediction. Our results show that the sons of polygynously mated females fledged in poor condition and therefore did not inherit their father's large forehead patch (a condition-dependent display trait) or mating status. From the female's perspective, polygynous pairing resulted in fewer recruited grandchildren than did a monogamous pairing. The reproductive value of sons did not outweigh the fecundity costs of polygyny because the low paternal care reduced the attractiveness of sons. When there are long-lasting parental effects on offspring attractiveness, costs of polygyny may include the production of nonsexy sons.

  20. Son preference in rural China: patrilineal families and socioeconomic change.

    Science.gov (United States)

    Murphy, Rachel; Tao, Ran; Lu, Xi

    2011-01-01

    This article draws on a survey conducted in six provinces in summer 2008 to investigate the determinants of son preference in rural China. The analysis confirms the conventional wisdom that son preference is embedded within patrilineal family structures and practices. We extend our analysis by exploring specific aspects of variation within patrilineal family culture. We find that the patrilineal group (clan) composition of villages and family participation in practices such as building ancestral halls and updating genealogies significantly influence son preference. Yet even though son preference is embedded within patrilineal family culture, our analysis suggests that over time the attenuation of son preference is likely. This is because determinants associated with socioeconomic change—for instance, higher levels of education, direct exposure to official policy education materials, higher income (a proxy for rural industrialization), and agricultural mechanization—all attenuate son preference. Being younger and female are also associated with weaker son preference, and both characteristics are likely to interact with education and industrialization to further dilute son preference in the longer term. Nevertheless, our findings suggest that concerted efforts are needed to ameliorate institutional discrimination against rural people in welfare provisioning and in labor markets, and to promote multiple dimensions of gender equality, including in land rights, wage rates, and education.

    This Internet-based study examined the association between Israeli parents' attributions regarding the cause of their son's homosexuality and their level of acceptance of their homosexual son. The sample (N = 57) was recruited via Internet Web sites (gay forums and support groups). Findings suggest that more essentialist (versus constructivist) causal attributions were associated with higher levels of parental acceptance. Length of time parents knew of their son's homosexual orientation predicted the degree to which their attributions were essentialist. Implications are discussed.

    2016-12-01

    Full Text Available ‘50 things my son doesn’t need me for’ (2011 explores the changing relationship between the artist and her son, and speaks about issues of loss. The artist’s interest is with the details and familiarity of everyday events. She focuses on unremarkable maternal experiences of daily life that relate to a particular time but which articulate both the extraordinary and the momentous, and represent the more fundamental changes that will inevitably occur as her son grows older. In the video, the artist is seen writing on a blackboard, and then erasing, 50 things that her son no longer needs her for. The video draws on the temporary nature of the items on the list; how quickly those things disappear. The artist focuses on the notion of loss as experienced from the mother’s perspective. The work explores feelings of maternal ambivalence, trapped in monotony, and the inherent contradictions with positive memories of closeness with her son.

    2014-11-01

    Full Text Available Cynthia R Collins Loyola University New Orleans, College of Social Sciences/School of Nursing, New Orleans, LA, USA Abstract: Emerging practice research on filial sources of health care support has indicated that there is a growing trend for sons to assume some responsibility for the health care needs of their aging parents. The purpose of this work is to propose that outcomes observed through a secondary analysis of data from a previous mixed methods research project, conducted with a sample of 60 elderly women residing in independent living centers, supports this concept in elder care. The present study is a retrospective interpretation utilizing the original database to examine the new question, “What specific roles do sons play in caregiving of their elderly mothers?” While daughters presently continue to emerge in existing health care studies as the primary care provider, there is a significant pattern in these data for older patients to depend upon sons for a variety of instrumental activities of daily living. As the baby-boomers age, there is more of cohort trend for their families to be smaller, adult daughters to be employed, and for adult children to be more geographically mobile. These factors may combine to make health care support networks more limited for the current aging population, challenging the elderly and their health care providers to revisit the cultural gender norms that are used to identify caregivers.

    2012-01-01

    SYNOPSIS Objective We address the extent to which parenting practices of fathers and mothers are associated with their sons’ parenting behaviors as young adults and whether adolescent behavior explains this association. Design Data come from 409 young men interviewed in the 2006 Young Adult study of the 1979 National Longitudinal Survey of Youth. Results Men whose fathers were positively involved with them when growing up report more positive parenting of their own children, a direct effect. Less harsh mothering and more positive fathering are associated with reduced adolescent behavior problems, and positive mothering is associated with positive adjustment of these young men as adolescents. However, neither adolescent problem behavior nor positive adjustment is associated with young men’s fathering of their own children, and thus does not explain the association between the fathering young men received and their own fathering behavior. Conclusions Men’s parenting of their sons can have a long-term direct effect on how their sons parent their own children. Although parenting is associated with both positive and negative behaviors of sons during adolescence, these adolescent behaviors are not directly linked to later parenting behavior when sons have their own children. More research is needed to examine mediation mechanisms for the intergenerational transmission of parenting. PMID:23284271

    In the works of Cervantes, one can observe a detailed knowledge of dental matters. Although some of his biographers think that this is the result of the very broad cultural knowledge of this distinguished Spanish writer, the authors of this paper think differently. Having studied and analyzed many documents referring to the Cervantes family, especially those which dealt with the strong influence the teachings of Cervantes' father had on his son, we have reached the conclusion that his father must have been a 16th Century dentist.

  4. "Fathers" and "sons" of theories in cell physiology: the membrane theory.

    2005-12-16

    The last 50 years in the history of life sciences are remarkable for a new important feature that looks as a great threat for their future. A profound specialization dominating in quickly developing fields of science causes a crisis of the scientific method. The essence of the method is a unity of two elements, the experimental data and the theory that explains them. To us, "fathers" of science, classically, were the creators of new ideas and theories. They were the true experts of their own theories. It is only they who have the right to say: "I am the theory". In other words, they were carriers of theories, of the theoretical knowledge. The fathers provided the necessary logical integrity to their theories, since theories in biology have still to be based on strict mathematical proofs. It is not true for sons. As a result of massive specialization, modern experts operate in very confined close spaces. They formulate particular rules far from the level of theory. The main theories of science are known to them only at the textbook level. Nowadays, nobody can say: "I am the theory". With whom, then is it possible to discuss today on a broader theoretical level? How can a classical theory--for example, the membrane one--be changed or even disproved under these conditions? How can the "sons" with their narrow education catch sight of membrane theory defects? As a result, "global" theories have few critics and control. Due to specialization, we have lost the ability to work at the experimental level of biology within the correct or appropriate theoretical context. The scientific method in its classic form is now being rapidly eroded. A good case can be made for "Membrane Theory", to which we will largely refer throughout this article.

    2014-01-01

    Recent research has documented the importance of parental reactions to disclosure for sexual minority youth (SMY) (e.g., Ryan, Huebner, Diaz, & Sanchez, 2009). The purpose of this study was to develop a deeper understanding of the parent perspective of the disclosure to family experience of SMY ages 14-21. In-depth interviews were conducted with eight parents in the United States who had experienced a child disclose their lesbian, gay, or bisexual (LGB) orientation to them. Constructivist grounded theory and symbolic interaction theory informed the methodology and data analysis for the project. Analysis revealed that the process of becoming the parent of an LGB son or daughter is an appropriate narrative to conceptualize the parental experience of the disclosure to family process. The findings highlight how disclosure introduces new roles into the existing family system, which affects the consideration and interpretation of the salience of particular identities, such as being the parent of an LGB son or daughter. Understanding how parents experience the disclosure to family process - particularly, how they understand and re-envision the meaning of being a parent - is crucial for research and intervention to help families become supportive of SMY. Limitations and suggestions for future research are presented. PMID:25685111

  7. Sexy sons: a dead end for cytoplasmic genes.

    Science.gov (United States)

    Zeh, Jeanne A

    2004-08-07

    Critics of sexual conflict theory argue that females may gain a net reproductive benefit from mating with manipulative males because the direct costs that they suffer may be offset by the production of sexy, i.e. manipulative, sons. However, this exclusive focus on nuclear gene effects represents an incomplete view of female fitness. Females differ fundamentally from males in transmitting not only nuclear genes but also a wide range of cytoplasmic genetic elements (CGEs) that can have profound effects, from male killing to influencing development of the nervous system and cognitive ability. Maternal transmission of CGEs has two major implications for sexual selection. First, the evolution of male fitness traits, such as sperm competitive ability, may be constrained because response to selection on mitochondrial genomes can occur only through the female line. Second, CGEs bear the direct costs of male manipulation but gain no indirect benefits when females produce sexy sons. This should result in perpetual antagonistic coevolution between nuclear genes involved in male manipulation and CGEs that promote female resistance to male sexually selected traits. Explicit consideration of the consequences of selection acting on CGEs is therefore necessary for a better understanding of the relationship between sexual selection and sexual conflict.

    Full Text Available Richard Wright’s Native Son has often been read as a socially-oriented text, seemingly neglecting its existence as a literary construct. Such readings gear towards identifying the text with such societal ills as racism and environmental impact on the individual, as if these are the only business of the text.In this paper, however, attention shifts from such external referents to the text itself, deconstructing the meaning of blindness already ascribed to the text as well as the meaning of silence as it is denotatively known. The uncovering of the textual meaning of each of these concepts will also serve either to compliment a character or to disparage same, and then the interweave of both concepts will result in reading the text as a tragedy. This study will be anchored on the provisions of Derrida’s deconstructive criticism.

    2016-07-01

    Food shortage is an important selective factor shaping animal life-history trajectories. Yet, despite its role, many aspects of the interaction between parental and offspring food environments remain unclear. In this study, we measured developmental plasticity in response to food availability over two generations and tested the relative contribution of paternal and maternal food availability to the performance of offspring reared under matched and mismatched food environments. We applied a cross-generational split-brood design using the springtail Orchesella cincta, which is found in the litter layer of temperate forests. The results show adverse effects of food limitation on several life-history traits and reproductive performance of both parental sexes. Food conditions of both parents contributed to the offspring phenotypic variation, providing evidence for transgenerational effects of diet. Parental diet influenced sons' age at maturity and daughters' weight at maturity. Specifically, being born to food-restricted parents allowed offspring to alleviate the adverse effects of food limitation, without reducing their performance under well-fed conditions. Thus, parents raised on a poor diet primed their offspring for a more efficient resource use. However, a mismatch between maternal and offspring food environments generated sex-specific adverse effects: female offspring born to well-fed mothers showed a decreased flexibility to deal with low-food conditions. Notably, these maternal effects of food availability were not observed in the sons. Finally, we found that the relationship between age and size at maturity differed between males and females and showed that offspring life-history strategies in O. cincta are primed differently by the parents. © 2016 European Society For Evolutionary Biology.

    2013-10-01

    Full Text Available Bakunin’s Son, a short novel by Sergio Atzeni, is the perfect embodiment of Bakhtin’s theory of the dialogic novel. The author sets his stories and characters - mostly humble outcast defeated people - in his own homeland, Sardinia. The accurately planned structure as an interview to thirty-two people reflects a multifarious reality with its complex rules and mentality expressed through different points of view, languages and ideologies. The protagonist’s story may result contradictory according to the different opinions of people who met him.

  14. SO(N) Singlet Projection Model on the Kagome Lattice

    Science.gov (United States)

    Block, Matthew; Kaul, Ribhu

    We explore the SO(N)-symmetric, nearest-neighbor singlet projection model on the two-dimensional kagome lattice using a quantum Monte Carlo simulation that employs the stochastic series expansion with global loop updates. There is no sign problem with this model, which is appropriate for nonbipartite lattices. We characterize the valence bond solid (VBS) phase that emerges for sufficiently large N and, by augmenting our model with either a next-nearest neighbor interaction that tends to order spins on the same sublattice, which encourages magnetic order for large N, or a plaquette-like interaction, which encourages VBS order for small N, we are able to examine the properties of the quantum phase transitions separating the two ordered phases. This work attempts to build off the success of investigations of the same SO(N) model on the triangular lattice and the analogous SU(N) model on the bipartite square, rectangular, and honeycomb lattices where the model is a natural generalization of the SU(2), spin-1/2 Heisenberg antiferromagnet.

    Experimental results are reported on the effect of magnesium silicate precipitation on the mechanisms and rate of borosilicate glass dissolution. Leaching experiments with SON68 glass, a borosilicate containing no Mg, were carried out in initially deionized water at 50 °C with a glass-surface-area-to-solution-volume ratio of 20,000 m{sup −1}. After 29 days of alteration the experimental conditions were modified by the addition of Mg to trigger the precipitation of Mg-silicate. Additional experiments were conducted to investigate the importance of other parameters such as pH or dissolved silica on the mechanisms of precipitation of Mg-silicates and their consequences on the glass dissolution rate. Mg-silicates precipitate immediately after Mg is added. The amount of altered glass increases with the quantity of added Mg, and is smaller when silicon is added in solution. A time lag is observed between the addition of magnesium and the resumption of glass alteration because silicon is first provided by partial dissolution of the previously formed alteration gel. It is shown that nucleation does not limit Mg-silicate precipitation. A pH above 8 is necessary for the phase to precipitate under the investigated experimental conditions. On the other hand the glass alteration kinetics limits the precipitation if the magnesium is supplied in solution at a non-limiting rate.

    Full Text Available Al plantearse como tema del artículo el de si las agencias son unidades administrativas especiales, el trabajo debe abordar dos conceptos aparentemente diferentes en cuanto al contenido y la génesis, pues de un lado se tiene conocimiento de las unidades administrativas especiales creadas con la finalidad de realizar actividades propias de un ministerio o departamento administrativo, y que, en consecuencia, siguiendo lineamientos jurisprudenciales, debían formar parte de la estructura de aquellos o estos. No obstante el reproche doctrinal referido a que a ciertas unidades administrativas se les otorgaba personería jurídica, llama la atención el cambio de criterio jurisprudencial que las avaló, y la manera en que a partir de la Constitución de 1991 se regularon unidades con o sin personería jurídica. Al abordar el tema de las agencias del Estado resulta relevante el origen anglosajón del término y la ausencia de características que las identifiquen, y la ausencia de un régimen común. Se hace especial mención a la reforma de 2011 y a cómo se crearon varias Agencias del Estado, algunas definidas como Unidades Administrativas Especiales, ante lo que cabe interrogarse sobre la correspondencia entre ambas nociones.

    Jean Alesi, former F1 racing driver, and his kids visited CERN on Monday 1st February 2010. The Bulletin and the Video productions team had the opportunity to meet him. The video interview is transcribed for your convenience. What attracted you to CERN, what was it that made you want to come? We talked at home with the children about places to see close to us, like CERN, where they are seeking to reproduce the origins of the world. These things are so far removed from what we ordinarily think and talk about, that they captured our imagination and made us want to come see for ourselves. We know that your son (Giuliano, 9 years) is interested in what is happening at CERN, so we'd like to ask him: how did he find out about it? Giuliano: I am very interested in the technologies used in laboratories, and the exploration of the Universe. Plus, I wanted to see some of the incredible machines. I enjoyed my visit a lot.

    Full Text Available What are the origin and source, as well as the meaning of the term Son of man as it appears in Mark? Is the background of the term to be found in the Old Testament, in Ezekiel and Daniel 7, or in the apocalyptic figure presented in 1 Enoch 47–71 and 4 Ezra 13? What does the intertextual reference of the term imply? Did the historical Jesus use the term as a reference to himself or to a divine (extraterrestrial deliverer he believed was coming to save the Jewish people, or is the term a post-Easter title applied retrospectively by the Gospel writer upon the pre-Easter Jesus? Did Jesus use the title as a self-designation, or did he use it in a self-effacing way to refer to himself as a mortal in contrast with God? Did he use the title as a generic designation for all humankind? What is the essence of the Gospel writer’s usage of the term? These questions are discussed in terms of the passages where Mark utilises the term.

    Climate data provide a challenging working basis for sonification. Both model data and measured data are assessed in collaboration with the Wegener Center for Climate and Global Change. The multi dimensionality and multi variety of climate data has a great potential for auditory displays. Furthermore, there is consensus on global climate change and the necessity of intensified climate research today in the scientific community and general public. Sonification provides a new means to communicate scientific results and inform a wider audience. SysSon is a user centered auditory platform for climate scientists to analyze data. It gives scientists broader insights by extracting hidden patterns and features from data that is not possible using a single modal visual interface. A variety of soundscapes to chose from lessens the fatigue that comes with repeated and sustained listening to long streams of data. Initial needs assessments and user tests made the work procedures and the terminology of climate scientists clear and informed the architecture of our system. Furthermore, experiments evaluated the sound design which led to a more advanced soundscape and improvement of the auditory display. We present a novel interactive sonification tool which combines a workspace for the scientists with a development environment for sonification models. The tool runs on different operating systems and is released as open source. In the standalone desktop application, multiple data sources can be imported, navigated and manipulated either via text or a graphical interface, including traditional plotting facilities. Sound models are built from unit generator graphs which are enhanced with matrix manipulation functions. They allow us to systematically experiment with elements known from the visual domain, such as range selections, scaling, thresholding, markers and labels. The models are organized in an extensible library, from which the user can choose and parametrize. Importance is

    2006-12-01

    Dr. Suh Yang Park was born in 1885 as a son of a butcher, which was the lowest class at that time in Korea. However, contact with western missionaries, including Dr. 0. R. Avison, provided him with an understanding of western civilization. After entering Chejungwon Medical School in 1900, Dr. Park learned basic sciences, basic medical sciences like anatomy and physiology, and other Western medical specialties such as internal medicine and surgery. He graduated from medical school in 1908 and received Government Certificate from Home Office, the first in Korea in this field, which granted the right to practice medicine. His certificate number was 4th overall. As both a doctor and a talented musician, Dr. Park actively participated in the social enlightenment movement. He was quite progressive in his time, having surpassed the social limitations as a son of a butcher, as well as actively propagating his knowledge of Western civilization onto others. After graduation, he had served as a professor at the school he graduated from, until he went into exile in Manchuria in 1917 due to the annexation of Korea by Japan in 1910. There, he opened a hospital and provided medical treatment for Koreans. He also established a school for young Koreans, inspiring them with a sense of nationalism. Also, Dr. Park was an active member of various Independence Movement Organizations in Manchuria. Then in 1932, at the time when Japan took control of Manchuria, his school was closed down. As a result, Dr. Park couldn't help but stop his anti-Japanese activities. In 1936, he returned to his homeland and passed away in 1940, just five years before the liberation of Korea from Japanese occupation.

On the other hand the glass alteration kinetics limits the precipitation if the magnesium is supplied in solution at a non-limiting rate. The concentration of i in solution was analyzed as well as that of boron. The quantity of i released from the glass is estimated with the assumption that i and B are released congruently at the glass dissolution front. The remained quantity of the element i is then supposed to be in the gel or in the secondary phase. In this paper, we do not make a difference between gel and hydrated glass using the same word 'gel' whereas Gin et al. [40] makes this difference. Recent papers [40,41] discussed about different key issues related to the passivation properties of the alteration layer including the hydrated glass

  11. BOOK REVIEW: Jean-Charles Houzeau et son temps

    Science.gov (United States)

    Sterken, C.; Verhas, P.

    2002-12-01

    This is a wonderful book. It describes the life and work of Belgian astronomer Jean-Charles Houzeau (1820-1888) and, as the last three words of the title indicate, it has a broader focus including the social, industrial and scientific context of the second part of the 19th century. This is set in a very broad international social context including social revolutions in Belgium and France, and the abolition of slavery in the United States. The biography clearly shows that this hard-working man was driven by science and justice, by individualism and generosity, by humor and sentiment. The book is divided in four parts, each part is placed in its own historical context. The first part "The apprentice, the master and his disciples" describes Houzeau's childhood and young years, his early scientific career at the Observatory in Brussels, and his relationship with Adolphe Quetelet. The evolution of this relationship is very well documented: the turbulent revolutionary Houzeau versus cool, moderated and diplomatic royalist Quetelet, the observer versus the mathematician theorist. But both were very dedicated teachers: Quetelet established public courses and after the Revolution of 1830 he contributed to the foundation of the University of Brussels; Houzeau was the peripatetic teacher wherever place he was, also after his return to Belgium. The second part is "The politician" and deals with Houzeau's political ideas and revolutionary attitudes and their consequences. His revolutionary ideas, though, were not confined to politics only: he also severely criticised the paucity of high-precision observations collected at the Royal Observatory in his days. Because he participated at revolutionary meetings, Houzeau was fired from his position at the Observatory by the Minister of Interior Affairs Charles Rogier. Thus started his peripathetic life, covering observational work in astronomy, geography, geodesy and natural sciences in many places in Belgium and abroad. The third

    Parents and adolescents often decide together whether the child should receive human papillomavirus (HPV) vaccine. However, few studies have investigated the dyadic nature of beliefs that affect this process. Data came from the 2010 HPV Immunization in Sons (HIS) Study, a national sample of 412 parents and their adolescent sons. We conducted dyadic multivariate logistic regression to examine the relationships between parents' and sons' HPV vaccine beliefs and their willingness to have the son receive the vaccine. Less than half of parents and sons were willing to have the sons receive HPV vaccine (43% and 29%, respectively). Willing parents and sons anticipated greater regret if the son did not receive HPV vaccine but later contracted an HPV infection (parent odds ratio [OR]=1.72, 95% confidence interval [CI]=1.24-2.40; son OR=1.51, 95% CI=1.04-2.19) (both pParents and sons were more willing to have the son receive HPV vaccine if they had higher anticipated regret about potential HPV infection and lower concerns about side effects. Communication campaigns may be able to target these beliefs to increase parents' and sons' willingness to seek HPV vaccination. Copyright © 2015 Elsevier Inc. All rights reserved.

    SON is a key component of the spliceosomal complex and a critical mediator of constitutive and alternative splicing. Additionally, SON has been shown to influence cell-cycle progression, genomic integrity, and maintenance of pluripotency in stem cell populations. The clear functional relevance of SON in coordinating essential cellular processes and its presence in diverse human tissues suggests that intact SON might be crucial for normal growth and development. However, the phenotypic effects of deleterious germline variants in SON have not been clearly defined. Herein, we describe seven unrelated individuals with de novo variants in SON and propose that deleterious variants in SON are associated with a severe multisystem disorder characterized by developmental delay, persistent feeding difficulties, and congenital malformations, including brain anomalies.

    Zaidi, Batool; Morgan, S Philip

    2016-12-01

    Even though Pakistan is a highly patriarchal society, it has not featured prominently in studies focusing on sex-selective abortion and sex ratios at birth. But with fertility declining and existing strong son preference-Pakistan has one of the highest desired sex ratios in the world-how will Pakistani families respond? In the pursuit of sons, will they have additional children or resort to sex-selective abortions? Or is there evidence that the pursuit of sons is weakening? Using data from three rounds of the demographic and health survey, we show clear evidence of son preference in fertility intentions, patterns of contraceptive use and parity progression ratios. More specifically, we find pervasive evidence that Pakistanis continue childbearing to have a son, to have more than one son and to have at least one daughter. We do not find consistent and convincing evidence that sex ratios at birth (which indicate sex-selective abortion) are increasing.

    We examined parents' and adolescents' preferences regarding potential strategies to increase human papillomavirus (HPV) vaccination rates, including offering the vaccine in alternative settings, concomitant administration of vaccines, and optimizing the structure of vaccination medical visits. A national sample of U.S. parents of adolescent boys aged 11-17 years (n = 506) and their sons (n = 391) completed online surveys in August and September 2010. We used analysis of variance for mixed designs to examine preferences for vaccination settings. Parents and sons were most comfortable with sons receiving HPV vaccine in a doctor's office. Parents of sons who had not visited their regular health care providers in the past year were more comfortable with sons receiving HPV vaccine at a public clinic (p parents whose sons had recent visits. Results from the son survey showed a similar pattern. Parents and sons reported moderate levels of acceptability of concomitant administration. They most preferred to have the three HPV vaccine shots administered during brief nurse visits. Offering HPV vaccine in alternative settings and administering it with other recommended adolescent vaccines may increase uptake among adolescent boys. Parents and sons may prefer HPV vaccines be administered during brief nurse visits. Copyright © 2012 Society for Adolescent Health and Medicine. Published by Elsevier Inc. All rights reserved.

    African-American males ages 13 through 24 are disproportionately affected by sexually transmitted infections (STIs) and human immunodeficiency virus (HIV), accounting for over half of all HIV infections in this age group in the United States. Clear communication between African-American parents and their youth about sexual health is associated with higher rates of sexual abstinence, condom use, and intent to delay initiation of sexual intercourse. However, little is known about African-American fathers' perceptions of what facilitates and inhibits sexual health communication with their preadolescent and adolescent sons. We conducted focus groups with 29 African-American fathers of sons ages 10-15 to explore perceived facilitators and barriers for father-son communication about sexual health. Participants were recruited from barbershops in metropolitan and rural North Carolina communities highly affected by STIs and HIV, and data were analyzed using content analysis. Three factors facilitated father-son communication: (a) fathers' acceptance of their roles and responsibilities; (b) a positive father-son relationship; and (c) fathers' ability to speak directly to their sons about sex. We also identified three barriers: (a) fathers' difficulty in initiating sexual health discussions with their sons; (b) sons' developmental readiness for sexual health information; and (c) fathers' lack of experience in talking with their own fathers about sex. These findings have implications for father-focused prevention interventions aimed at reducing risky sexual behaviors in adolescent African-American males. © 2017 Wiley Periodicals, Inc. © 2017 Wiley Periodicals, Inc.

    This study describes a test of the Fathers and Sons Program for increasing intentions to avoid violence and reducing aggressive behaviors in 8- to 12-year-old African American boys by enhancing the parenting skills satisfaction and parenting behaviors of their nonresident fathers. The study included 158 intervention and 129 comparison group families. Structural equation model results indicated that the intervention was effective for improving fathers' parenting skills satisfaction, which was positively associated with sons' satisfaction with paternal engagement. Sons' paternal engagement satisfaction was positively associated with their intentions to avoid violence. Although aggressive behaviors were lower for comparison group sons, the intervention effectively reduced sons' aggressive behaviors indirectly by enhancing fathers' parenting behaviors. Support for family-centered youth violence prevention efforts is discussed. © 2013 The Authors. Child Development © 2013 Society for Research in Child Development, Inc.

    China is characterized by a low fertility intention, a strong preference for sons, as well as a stringent birth control policy. In this study, we used data from a Fertility Intention and Behavior Survey of 2101 questionnaires conducted in 2013 in Shaanxi Province of northwestern China, and event history analysis methods to examine the effect of fertility intention and preference for sons on the probability of having a second child. The results not only validate the correlation of fertility intention with having a second child empirically, even in the low fertility intention and stringent birth control context of China, but also show that women with a preference for sons were less likely to have a second child. Women with son preference turn to sex-selective abortion to ensure that their first child is a son, thus reducing the likelihood of a second child and decreasing the fertility rate. Our findings also shed light on China's potential fertility policy adjustment.

    Full Text Available Abstract Background Licensed for use in males in 2009, Human Papillomavirus (HPV vaccination rates in adolescent males are extremely low. Literature on HPV vaccination focuses on females, adult males, or parents of adolescent males, without including adolescent males or the dynamics of the parent-son interaction that may influence vaccine decision-making. The purpose of this paper is to examine the decision-making process of parent-son dyads when deciding whether or not to get vaccinated against HPV. Methods Twenty-one adolescent males (ages 13–17, with no previous HPV vaccination, and their parents/guardians were recruited from adolescent primary care clinics serving low to middle income families in a large Midwestern city. Dyad members participated in separate semi-structured interviews assessing the relative role of the parent and son in the decision regarding HPV vaccination. Interviews were recorded, transcribed, and coded using inductive content analysis. Results Parents and sons focused on protection as a reason for vaccination; parents felt a need to protect their child, while sons wanted to protect their own health. Parents and sons commonly misinterpreted the information about the vaccine. Sons were concerned about an injection in the penis, while some parents and sons thought the vaccine would protect them against other sexually transmitted infections including Herpes, Gonorrhea, and HIV. Parents and sons recalled that the vaccine prevented genital warts rather than cancer. The vaccine decision-making process was rapid and dynamic, including an initial reaction to the recommendation for HPV vaccine, discussion between parent and son, and the final vaccine decision. Provider input was weighed in instances of initial disagreement. Many boys felt that this was the first health care decision that they had been involved in. Dyads which reported shared decision-making were more likely to openly communicate about sexual issues than those

  6. Steve Biko Christ-figure: A black theological Christology in the Son of Man film

    Directory of Open Access Journals (Sweden)

    Katleho K. Mokoena

    2017-10-01

    Full Text Available Son of Man (2006 is the first Jesus film to be produced in South Africa and the first Jesus film with an all-black cast amongst all films about the life of Jesus. Son of Man retells the story of Jesus from the pre-1994 South African context and the transition to democracy. The film portrays a Jesus who is concerned about social justice and seeks to dismantle systems that perpetuate and maintain subjugation, oppression, discrimination and marginalisation. The film reinforces the ideology of black consciousness and the praxis of black theology creatively and artistically through film. Jesus in Son of Man embodies the life of Stephen Bantu Biko, and Steve Biko is thus given a Christ-figure around four things: non-violence, ideology, disappearance and death. A black Christological perspective is used to analyse the nature of Jesus Christ in Son of Man.

    The objective of the study was to examine the mutation rates of Y-chromosomal STR from father-son pairs. The paternity in these cases was confirmed previously with the use of autosomal STR system performing standard analyses of genetic profiles of the mother, child and putative father (PI > = 100000). We examined 200 father-son sample pairs from Northern Poland using the Y-STR 18-plex. We identified eleven mutations. Five mutations resulted in the gain of a repeat in the sons' chromosome and six resulted in a loss of a repeat. All the samples resulted in single repeat mutations from one sample, which contained a two repeat loss at DYS385. The overall average mutation rate estimate was 0.0031.There was no significant difference in the mutation rate between Y-STR loci of the 200 tested father-son pairs and the YHRD base.

    OBJECTIVES: Previous studies indicate an increased risk of cryptorchidism, incomplete testicular descent, among sons of women working with pesticides. This study assessed the risk of cryptorchidism among boys of parents employed as horticultural workers and farmers using nationwide registers...... of mothers in other occupations (15 511 cases). Paternal occupation as farmer was unrelated to the risk among sons. Maternal occupation as a horticultural worker was associated with a non-significantly increased risk (72 cases; HR 1.20, 95% CI 0.95-1.52). A similar association was found for paternal...... horticultural workers. Sons of maternal farmers or horticultural workers who likely worked in the first trimester were not at increased risk of cryptorchidism. CONCLUSIONS: This nationwide cohort study found a slightly increased risk of cryptorchidism in sons of maternal horticultural workers and farmers...

    This paper provides a new explanation for the narrowing and reversal of the gender education gap. It highlights the indirect effect of returns to human capital on parents' preferences for sons and the resulting demand for children and education. We assume that parents maximize the full income of their children and that males have an additional income, independently of their level of education. This additional income has two effects. First, it biases parental preferences towards sons. Second, ...

  16. Like daughter, like son? Fertility decline and the transformation of gender systems in the family

    Directory of Open Access Journals (Sweden)

    Keera Allendorf

    2012-10-01

    Full Text Available BACKGROUND An important question for population research is whether fertility decline transforms gender systems. OBJECTIVE This paper contributes to answering this broad question by examining how fertility decline may change the relative value and roles of daughters versus sons in families. First, I outline theoretical pathways, suggesting that a key factor is the gender composition of families. As fertility declines, the proportion of families with children of only one gender increases, which may facilitate greater gender symmetry between daughters and sons. Second, I explore how fertility decline may be transforming the relative value and roles of sons and daughters in practice in one place. METHODS The analysis draws primarily on semi-structured interviews with 30 respondents living in one Indian village. RESULTS In recent decades, fertility has declined to at least replacement levels. Respondents also perceive changes in the gender system, including less son preference, more equal schooling for sons and daughters, more freedom in marriage and pre-marital relationships, and perhaps greater daughter support of parents in old age. CONCLUSIONS The results describe changes in the relative value, treatment, and behavior of sons and daughters that are consistent with the theorized effects of fertility decline. Future research is needed, however, to determine whether fertility decline makes a unique causal contribution to changes in the gender system.

  17. Some reflections on a case of mother/adolescent son incest.

    Science.gov (United States)

    Shengold, L

    1980-01-01

    A rare case of mother/adolescent son incest is presented. The son, treated in analysis, was not psychotic. Questions are raised about why father/daughter incest appears to be much more common than mother/son incest. Part of the answer, I speculate, has to do with the special psychic dangers for both mother and son, perhaps phylogenetically-based, which attach to the fantasy and the possibility of impregnating the mother. Where the incest taboo is violated, the primary responsibility would appear to be the parent's; the parent is frequently motivated by a compulsion to repeat his or her own incestuous past. In the case presented the probably psychotic mother had raised her son to look like a girl for several years, and he had been the victim of a homosexual assault at the age of 6. The incest at puberty seems to have helped him reverse a psychic position of subjection to the pre-oedipal mother, to have modified his rage and reinforced his masculinity. It also produced some of the arrogance, alongside a need for failure and punishment that evoke the legend of Oedipus. The mother, fearful of the possibility of getting pregnant, had abruptly stopped the incest. It had been repressed, and became conscious again when the son entered analysis. He then left his treatment without being able to work through much of the terror consequent to the consummation of incest, and with some of the feeling of oedipal triumph retained.

  18. Daughters increase longevity of fathers, but daughters and sons equally reduce longevity of mothers.

    Science.gov (United States)

    Jasienska, Grazyna; Nenko, Ilona; Jasienski, Michal

    2006-01-01

    Reproduction is energetically and physiologically expensive, and an individual investing resources into producing offspring should suffer costs such as deterioration in health condition and possibly shorter life span. Since the energetic and nutritional demands of pregnancy and breastfeeding render reproductive costs much higher in women than in men, women with a large number of children should show signs of deterioration in condition, while men with large families should not. However, whether reproductive costs reduce longevity in women is still questionable, and in men this issue has not been adequately addressed. In addition, since sons are energetically more expensive to produce than daughters, having sons should have a more pronounced negative impact on maternal longevity than having daughters. Here we document a striking disparity in the impact of children on the life span of mothers and fathers in a Polish rural population. We show for the first time that number of daughters was positively related to a longer life span of their fathers, increasing their longevity on average by 74 weeks per daughter born, while number of sons did not have a significant effect on paternal longevity. In contrast, in women, the number of daughters and number of sons reduced maternal longevity and did so to the same extent, on average by 95 weeks per son or daughter, indicating that for women, the costs of having sons and daughters are similar.

  2. Independent Contributions of Early Positive Parenting and Mother-Son Coercion on Emerging Social Development.

    Science.gov (United States)

    Akcinar, Berna; Shaw, Daniel S

    2017-09-21

    In the current study, we explored associations between parent-child coercion and positive parenting in the toddler period in relation to children's social-behavioral development during the school-age period. The data were drawn from the Pitt Mother & Child Project, a sample of 310 low-income, ethnically diverse boys. Drawing on tenets of both attachment and social learning theory, it was hypothesized that coercive mother-son interaction would lead to reductions in positive maternal parenting in the toddler period, and that both positive parenting and mother-son coercion in the toddler period would contribute to children's conduct problems at school entry and lower social skills and peer rejection in middle childhood. The results were largely confirmed, such that mother-son coercive interaction at 18 months was related to decreases in positive parenting at 24 months. Additionally, mother-son coercive interaction and positive parenting at 24 months were linked to child conduct problems at age 5, which in turn predicted child social skills and peer rejection during middle childhood. In addition to indirect effects through child conduct problems, mother-son coercion continued to be independently related to school-age peer rejection. The findings are discussed with respect to the importance of early coercive interactions in the growth of child social-behavioral development from early to middle childhood.

  5. Fathers in a Coma: Father-Son Relationships in Neil Jordan’s Fiction

    Directory of Open Access Journals (Sweden)

    Samuele Grassi

    2008-03-01

    Full Text Available This paper will analyze father-son relationships in some of Neil Jordan’s novels and short stories. His writing often deals with this theme, as well as with the gap between old and young generations. His works are often built around the contrast between tradition and modernity, such as de Valera’s idealised concept of Nation and contemporary, ‘global’ Ireland. Thus following a consistent trend in contemporary Irish literature, Jordan develops new narratives of the Nation. What do fathers do? What do sons do? How do fathers respond to their sons’ actions and behaviours, and vice versa? These questions will be addressed and, possibly, be answered. In Neil Jordan’s work, father-son struggles have their counterpart in the process of the revision of ideologies and norms of tradition (patriarchy and the Catholic Church. At the same time, they are accompanied by a strong feeling of belonging to Ireland as a Nation.

    2002-01-01

    Reported cases of mother-son incest are very rare in the psychoanalytic literature; the fact of such incest, however, may not be so rare as has generally been believed. A detailed case report of the analysis of an adult with a history of severe physical, sexual, and verbal abuse, including consummated incest with his mother during latency, is considered in the context of other reported studies. The author raises some issues of resistance and countertransference that may influence the reporting, treatment, and perhaps even recognition of cases of mother-son incest.

    War service increases the risk of post-traumatic stress disorder (PTSD) to combatants, and has been shown to increase the risk of PTSD in their offspring. The extent to which there is an excess compared with the general population is not yet established, nor whether PTSD increases the risk of other psychiatric problems. A national sample of 133 sons and 182 daughters of a cohort of 179 Australian Vietnam veterans' families were assessed in person, using structured psychiatric interviews. The prevalence of trauma exposures, DSM-IV (Diagnostic and Statistical Manual of Mental Disorders Fourth Edition) diagnoses and suicidality were compared with the Australian Bureau of Statistics' 2007 National Survey of Mental Health and Wellbeing data matched for age and sex. The risk of mental health problems potentially attributable to PTSD was also assessed. Sons and daughters were more likely than population expectations to report exposures to natural disasters, fire or explosions and transport accidents, and sons more likely to report exposure to toxic chemicals whereas daughters were more likely to report sexual assault. Sons and daughters had higher prevalences of alcohol and other substance dependence, depression and anxiety, and PTSD, and children's PTSD was associated with substance dependence, depression and suicidal ideation. There were strong associations between children's PTSD and comorbid conditions of substance use disorders, depression and anxiety. Higher rates of mental health problems in veterans' families, together with comorbidity with PTSD and the link between veterans' and children's PTSD, suggest that the effects of trauma may continue into subsequent generations.

    Little is known about fathers' attitudes toward human papillomavirus (HPV) vaccination in low-resource settings. We sought to determine the awareness of HPV vaccination among Honduran fathers, and to assess their intention to accept HPV vaccination for their sons and daughters. We conducted 100 structured interviews of fathers recruited from medical and business settings between May 2007 and June 2008. After assessing baseline knowledge, fathers received a brief explanation of HPV infection, cervical cancer, genital warts, and HPV vaccination. They were then asked whether they would accept HPV vaccination for their sons and daughters. Prior to receiving information about HPV, 85% of fathers believed that cervical cancer was preventable, over two-thirds could correctly name some form of prevention, 22% of fathers had heard of HPV, and 17% had heard of HPV vaccination. After receiving HPV-related information, 100% of fathers intended to accept HPV vaccination for their sons and 94% intended to accept HPV vaccination for their daughters. Few Honduran fathers were aware of HPV or HPV vaccination, but after receiving information, most would accept HPV vaccination for their sons and daughters.

    This paper explores the ways in which women’s sterilisation decisions are influenced by the combination of a preference for male children and a desire for smaller family size among young married women in two urban slums in Bengaluru, India. While both son preference and an emphasis on sterilisation are well-known demographic characteristics of most south-Asian countries, relatively little research has been conducted that links the two. We take advantage of a longitudinal survey of 416 unsterilised married women aged 16–25 to explore how having sons and the number of children influence a woman’s sterilisation decision. Discrete-time event-history techniques are used to estimate two models: the first examines the effect of having sons and number of children separately, and the second examines them in combination in the form of an interaction. The results suggest sterilization is motivated by son preference mainly at lower parities (three or fewer children) and by concerns about family size at higher parities. Understanding how sterilisation and other reproductive behaviours are influenced by the interaction of family size and sex preferences will help policymakers and programmers to meet the needs of women while continuing to address discriminatory behaviour against females.

    Despite low to moderate convergent correlations, assessment of youth typically relies on multiple informants for information across a range of psychosocial domains including parenting practices. Although parent-youth informant discrepancies have been found to predict adverse youth outcomes, few studies have examined contributing factors to the explanation of informant disagreements on parenting practices. The current study represents the first investigation to concurrently examine the role of mother and son's self-reported affective dimensions of temperament and depression as pathways to informant discrepancies on parenting practices. Within a community sample of 174 mother-son dyads, results suggest that whereas mother's self-reported temperament evidenced no direct effects on discrepancies, the association between the product term of mother's negative and positive temperament and discrepancies on positive parenting was fully mediated by mother's depression (a mediated moderation). In contrast, son's self-reported temperament evidenced both direct and indirect effects, partially mediated by depression, on rating discrepancies for positive parenting. All told, both son's self-reported affective dimensions of temperament and depression contributed to the explanation of discrepant reporting on parenting practices; only mother's self-reported depression, but not temperament, uniquely contributed. Results highlight the importance of considering both parent and youth's report in the investigation of informant discrepancies on parenting practices.

    The similarity between rules used by mothers and those used by sons was extensive. Results suggest that research should emphasize the process by which children come to employ multidimensional rules and the role of parental models in this process. Current research in moral judgments largely ignores the rule-governed nature of children's judgments.…

    Prenatal exposure to elemental mercury may be a potential hazard for the offspring of female dental personnel working with dental amalgam. The aim of this study was to investigate whether potential in utero exposure to mercury might have affected the development of nervous system of the sons of Swedish female dental personnel leading to an increased risk of neurological disease or intellectual disability. We used national Swedish registers to investigate risks for diseases potentially related to adverse effects on neurodevelopment. Sons of female dentists (n=1690) and dental nurses (n=10,420) were compared with cohorts consisting of sons of other female healthcare personnel. Due to changes in mercury exposure in dentistry during the study period, analyses were stratified by decade of birth. Hazard ratios (HRs) were calculated using Cox proportional hazard models. We found no elevated risk for neurological disease, epilepsy or intellectual disability among the sons of dental personnel during any of the decades studied. HRs for neurological disease among the dental nurse cohort were even below 1.00 during the 1970s and 1980s. A low number of events resulted in uncertainty regarding results in the dentist cohort. We did not find any support for the hypothesis that mercury exposure in Swedish dentistry during the 1960s, 1970s or 1980s had any effect on the incidence of neurological disease or intellectual disability among the sons of female dental personnel. Our results imply that current use of dental amalgam should not represent an elevated risk for neurological disease or intellectual disability among the offspring of dental personnel.

    Data science has attracted a lot of attention, promising to turn vast amounts of data into useful predictions and insights. In this article, we ask why scientists should care about data science. To answer, we discuss data science from three perspectives: statistical, computational, and human. Although each of the three is a critical component of data science, we argue that the effective combination of all three components is the essence of what data science is about.

    A qualitative phenomenological study of parents of addicted male adolescents who were residents of a Jewish therapeutic community (TC) describes and interprets the parents' perceptions of the recovery process. Deep, semistructured interviews with 14 parents provided the data. The parents' perceptions were clustered into three main themes of meaning: (a) the process of change, (b) the experiences of family members in the course of the son's recovery process, and (c) the parents' perception of the treatment at Retorno. According to the parents, the admission of their sons into the TC brought notable relief to the family life, which enabled the whole family to begin a recovery process. The findings support the positive criminology perspective that emphasizes the disintegration-integration vector as significant in the recovery process. Recommendations for intervention planning are provided.

    1992-09-01

    We reported a 49-year-old mother and her 28-year-old son with autosomal dominantly inherited bulbar spinal muscular atrophy (AD-BSMA). They showed progressive bulbar paresis, muscle wasting and weakness dominant in the proximal groups of limb muscles, and finger tremor. Onset of illness was in adult life. In laboratory examinations, elevated creatine kinase in serum and neurogenic changes either in EMG or muscle biopsy were noted. The son had neither gynecomastia nor abnormal sexual hormone levels which were observed in the sex-linked recessive bulbar spinal muscular atrophy (SR-BSMA). Elongation due to the CAG repeats at the androgen receptor gene of the X chromosome in SR-BSMA was not detected. In conclusion, it is clear that AD-BSMA is different from SR-BSMA on the basis of clinical and genetical aspects.

    The association of congenital heart defect and ocular malformations is involved in several genetic syndromes, metabolic diseases and environmental entities. We report here on father and son, both presenting with the combination of atrial septal defect and congenital ocular anomalies in Axenfeld-Rieger anomaly. The son had anterior iridotrabecular dysgenesis and posterior embryotoxon bilaterally, corneal leucoma and marked iridial vascularization at right. The father had bilateral anterior iridotrabecular dysgenesis, posterior embryotoxon and nystagmus, and corneal leucoma at left. No additional malformations were noted in these patients. The Axenfeld-Rieger syndrome seems to be a spectrum of developmental disorders. The present report confirms the existence of a specific Axenfeld-Rieger phenotype associated with congenital heart defect. Atrial septal defect is the anatomic type of congenital heart defect linked to this condition.

    Full Text Available This paper examines the extent to which prospective engineers follow in their parents’ footsteps. Specifically, we investigate the connection between fathers’ and mothers’ employment in the engineering profession and the career plans of sons and daughters. We develop a number of reasons to expect an occupation-specific intergenerational association in this field, as well as hypotheses regarding gender-specific role-modeling. Data are drawn from the UCLA HERI Freshman Survey data spanning 1971 to 2011. The results point to clear and substantial effects on sons and daughters’ plans to pursue engineering, connections that cannot be explained by typical pathways such as social background, education and values. The evidence points to a pattern of increasing salience of mothers with respect to the career plans of their children, especially their daughters. The implications of these findings for the under-representation of women in engineering and for gender-specific family dynamics are discussed in the conclusion.

    2015-01-01

    In 1987, 4 per cent of girls were adopted within China. Why? Unlike infanticide, abandonment rids parents of daughters while preserving the supply of potential brides. In fact, an erstwhile tradition common in Fujian and Jiangxi provinces had parents of sons adopting an infant girl to serve as a future daughter-in-law and household help. Analysing a nationally representative 1992 survey of children, we found that: (1) girl adoptions were concentrated in the above-mentioned provinces; (2) girls were predominantly adopted by families with sons; (3) adopted girls faced substantial disadvantage as measured by school attendance at ages 8-13. In the 1990s, as the sex ratio at birth climbed, were girls aborted rather than abandoned? Observing that in the 2000 census too many girls appear in families with older sons, we estimated that at least 1/25 girls were abandoned in the 1990s, a proportion that in Fujian and Jiangxi may have peaked at 1/10 in 1994.

  20. Cultural bias in the SON-R test: comparative study of Brazilian and dutch children

    Peter J. Tellegen

    Full Text Available The present study, including 83 Brazilian and 51 Dutch children, evaluated the presence of cultural bias in items of the SON-R 5½-17 that make use of concrete objects and situations. Two procedures were followed to detect item bias. The first consisted of asking the children, immediately after an incorrect answer, whether they recognized the pictures. The second procedure compared item difficulties of the Brazilian children with those of the Dutch children belonging to the standardization sample of the SON-R 5½-17. Fourteen items were detected with bias: ten of these favored the Dutch group and four the Brazilian group. The cultural disadvantage for Brazilian children is rather small, taking the large amount of investigated items into account. This study indicated which items of the SON-R 5½-17 should be improved, not only for reasons of cultural bias, but also because children, irrespective of their cultural background, encountered problems with the recognition of several pictures.

    This paper presents the physics case for a new high-energy, ultra-high statistics neutrino scattering experiment, NuSOnG (Neutrino Scattering on Glass). This experiment uses a Tevatron-based neutrino beam to obtain over an order of magnitude higher statistics than presently available for the purely weak processes νμ + e- → νμ + e- and νμ + e- → νe + μ-. A sample of Deep Inelastic Scattering events which is over two orders of magnitude larger than past samples will also be obtained. As a result, NuSOnG will be unique among present and planned experiments for its ability to probe neutrino couplings to Beyond the Standard Model physics. Many Beyond Standard Model theories physics predict a rich hierarchy of TeV-scale new states that can correct neutrino cross-sections, through modifications of Zνν couplings, tree-level exchanges of new particles such as Z‧'s, or through loop-level oblique corrections to gauge boson propagators. These corrections are generic in theories of extra dimensions, extended gauge symmetries, supersymmetry, and more. The sensitivity of NuSOnG to this new physics extends beyond 5 TeV mass scales. This paper reviews these physics opportunities.

  2. Multivariate Multiple Regression Models for a Big Data-Empowered SON Framework in Mobile Wireless Networks

    Directory of Open Access Journals (Sweden)

    Yoonsu Shin

    2016-01-01

    Full Text Available In the 5G era, the operational cost of mobile wireless networks will significantly increase. Further, massive network capacity and zero latency will be needed because everything will be connected to mobile networks. Thus, self-organizing networks (SON are needed, which expedite automatic operation of mobile wireless networks, but have challenges to satisfy the 5G requirements. Therefore, researchers have proposed a framework to empower SON using big data. The recent framework of a big data-empowered SON analyzes the relationship between key performance indicators (KPIs and related network parameters (NPs using machine-learning tools, and it develops regression models using a Gaussian process with those parameters. The problem, however, is that the methods of finding the NPs related to the KPIs differ individually. Moreover, the Gaussian process regression model cannot determine the relationship between a KPI and its various related NPs. In this paper, to solve these problems, we proposed multivariate multiple regression models to determine the relationship between various KPIs and NPs. If we assume one KPI and multiple NPs as one set, the proposed models help us process multiple sets at one time. Also, we can find out whether some KPIs are conflicting or not. We implement the proposed models using MapReduce.

  3. The Experiences and Meanings That Shape Heterosexual Fathers' Relationships With Their Gay Sons in South Africa.

    2016-12-01

    Gay men's relationships with their mothers are likely to be more positive than their relationships with their fathers, and fathers are less likely to be told, less likely to be told first, and more likely to react negatively to disclosure than mothers. Drawing on an interpretivist approach, an individual in-depth interview strategy was adopted in the study as a means of gathering data from six Afrikaans-speaking White fathers, between the ages of 53 and 61 years (median: 55.5 years), residing in Gauteng, South Africa. Interviews were audio-recorded and transcribed for later coding and analysis. Through thematic network analysis, eight organizing themes emerged and were explored. For the purpose of this article only three organizing themes are discussed, namely "subliminal awareness prior to coming out," "epistemic rupture of internal systems of ideas/beliefs," and "acceptance as a complex and ongoing dialectical and reconciliatory process." The themes support the view that most parents are neither totally rejecting nor fully accepting of their gay sons. Although the fathers may have attained a level of "loving denial" in the relationships with their gay sons, most continue to struggle with the meaning and expression of same-sex sexuality. Despite these challenges, it is recognized that the fathers are adapting to changing circumstances and are trying to find ways to tolerate, accommodate, and in some ways accept their gay sons.

    The purpose of this article was to identify the information parents and their adolescent sons deem important when making the decision to get vaccinated against human papillomavirus (HPV). Twenty-one adolescent males (ages 13 to 17), with no previous HPV vaccination, and their parents were recruited from adolescent primary care clinics serving low- to middle-income families in a large Midwestern city. Dyad members participated in separate semistructured interviews eliciting the information participants felt would increase vaccine uptake and series completion via media and clinic-based sources. Interviews were recorded, transcribed, and coded using inductive content analysis. Overall, participants felt fear-based messages would be most effective for increasing vaccination uptake through commercials. When describing clinic messages, parents and sons felt the most important component was a recommendation for vaccination from the health care provider (HCP). Additionally, parents desired more information about the vaccine from the HCP than the sons, including cost, number of shots, and time since the approval of the vaccine for males. Compared with the clinic message, the commercial message was a vector for vaccine awareness, whereas the clinic message was a source of vaccine information. Vaccine initiation messages should provide vaccine information and come from an HCP, whereas completion messages should remind the patient why they initiated the vaccine and can come from any medical staff. Family/individual-focused interventions should be tailored to message source, timing, and target audience. This information can be used to guide public health professionals in the development of interventions to increase vaccine uptake. PsycINFO Database Record (c) 2014 APA, all rights reserved.

    Based on the recommendations of the sub-workgroup on trauma and dissociative disorders, the American Psychiatric Association (APA) removed the "bereavement exclusion" from the criteria for major depression in DSM-5. In addition, proposed DSM-5 research criteria for persistent complex bereavement disorder (PCBD) were included in the new manual in a section for conditions and criteria needing further research. We describe a case that warranted such a diagnosis. The patient was a 52- year-old woman who was admitted to the inpatient unit of our clinic on the birthday of her son who had died 18 months earlier. She was diagnosed with a manic episode with psychotic symptoms according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision (DSM-IV-TR) criteria and was treated accordingly. Three months after discharge, she made a suicide attempt and was admitted and re-assessed. During this admission, she completed the Inventory of Complicated Grief (ICG), the Mood-Spectrum Rating Scale (MOODS-SR), and the Trauma and Loss Spectrum questionnaire (TALS-SR). She endorsed symptoms of intense yearning for her son, feelings of shock and disbelief, anger and bitterness related to his death, estrangement from others, auditory, tactile and visual hallucinations of the deceased, and intense emotional reactivity to memories of her son. These symptoms were sufficiently prolonged and severe to meet criteria for complicated grief. While complicated grief appeared to be the primary diagnosis for this patient, when she was diagnosed using only DSMIV-TR criteria, her treatment failed to address herprimary problem. This case draws attention to the occurrence of manic-like symptoms as well as depression-like manifestations following bereavement and highlights the importance of including the syndrome of complicated grief in the diagnostic nomenclature.

    Full Text Available Abstract Background Androgens are crucial for normal testicular descent. Studies show that some pesticides have estrogenic or antiandrogenic effects, and that female workers exposed to pesticides have increased risk of having a boy with cryptorchidism. The main objective of the present study was to investigate whether pregnant women exposed to pesticides due to their work in horticulture experience excess risk of having sons with cryptorchidism. Methods We conducted a cohort study of pregnant women working in horticulture using four cohorts including one cohort established with data from the departments of occupational medicine in Jutland and Funen and three existing mother-child cohorts (n = 1,468. A reference group was established from the entire Danish population of boys born in the period of 1986-2007 (n = 783,817. Nationwide Danish health registers provided information on birth outcome, cryptorchidism diagnosis and orchiopexy. The level of occupational exposure to pesticides was assessed by expert judgment blinded towards outcome status. Risk of cryptorchidism among exposed horticulture workers compared to the background population and to unexposed horticulture workers was assessed by Cox regression models. Results Pesticide exposed women employed in horticulture had a hazard ratio (HR of having cryptorchid sons of 1.39 (95% CI 0.84; 2.31 and a HR of orchiopexy of 1.34 (0.72; 2.49 compared to the background population. Analysis divided into separate cohorts revealed a significantly increased risk of cryptorchidism in cohort 2: HR 2.58 (1.07;6.20 and increased risk of orchiopexy in cohort 4: HR 2.76 (1.03;7.35, but no significant associations in the other cohorts.

  12. Data and Analysis Methods of the Son-O-Mermaid and MERMAID Experiments

    Science.gov (United States)

    Simon, J. D.; Simons, F. J.; Nolet, G.

    2014-12-01

    Here we present, for the first time, the results from pilot deployments of the Son-O-Mermaid project, an autonomously drifting, oceangoing data-collection platform that can be cheaply deployed without the need for a costly research vessel, and that records and transmits hydroacoustic signals (with a target of those generated by teleseismic earthquakes) in near real-time. Both deployments employ three identical hydrophones spaced about 70 cm apart at the end of a 700 m long cable attached to a surface buoy that houses electronics, communications, and a GPS location package. The maiden voyage occurred October 8, 2012, in Exuma Bay, Bahamas and returned 25 hours of acoustic data. A second deployment is to take place in September 2014, with near-immediate data relay via Iridium modem. The experimental setup is different from the MERMAID instrument, which sinks to a midcolumn depth and surfaces to transmit waveforms when an event detection algorithm is triggered. MERMAIDs have recorded hundreds of seismic traces from 18 active floats in the Indian and Mediterranean Oceans with a signal-to-noise ratio suitable for global tomography. As with earthquake early-warning studies, both Son-O-Mermaid and MERMAID benefit from rapid and accurate event detection, discrimination, and measurement technology. With this triple purpose in mind we continue to improve methods (in the time-domain, via spectrogram analysis and using wavelets) that we illustrate on the latest and some of the older data, as well. While hydroacoustic data have numerous other applications beyond seismology (whale calls, ice calving, weather patterns, and so on) the Son-O-Mermaid and MERMAID instruments may potentially revolutionize seismic data collection in the oceans. Moreover, in the near future they will be fitted with more or different instruments, becoming multipurpose and multidisciplinary platforms for all types of scientific research in and of the oceans. In seismology we envision a future when the

    Full Text Available Anaptyxis is a sound appearing that is not found in the original structure of the word. There are three types of anaptyxis: prothesis, epenthesis and epithesis. Epithesis is a vowel or consonant appearing at the end of a word which is not found in the original structure of it. Although, there isn’t not so much example, both vowel and consonant reproduction is seen even in the last sound of the word; but the derivative sound isn’t the same, standard in the whole dialects and accents. Nevertheless some derivative sounds have an intense in a specific region, they aren’t seen in the other areas or has rare example. In this study, the epithesis in the loan words in Turkish will be emphasized. Bir kelimede aslında bulunmayan bir sesin sonradan ortaya çıkmasına ses türemesi denir. Ses türemesinin üç çeşidi vardır: ön türeme, iç türeme, son türeme. Son türeme, kelimenin aslında bulunmayan bir ünlü veya ünsüzün kelime sonunda belirmesidir. Örneği fazla olmamakla birlikte son seste de hem ünlü hem de ünsüz türemesi görülür. Ancak türeyen sesler standart olarak bütün lehçe ve ağızlarda ortak değildir. Türeyen bazı sesler belli bir bölge içerisinde yoğunlaşırken, bazı bölgelerde görülmemekte veya sadece birkaç, hatta bir örnekle sınırlı kalabilmektedir. Bu çalışmada Türkçede alıntı kelimelerdeki son türeme örnekleri üzerinde durulacaktır.

  16. The Tragedy of Hamlet, Son of an Organic Chemist of Denmark

    Brisbois, Ronald G.

    2004-04-01

    Once faced with structure reactivity relationships in the context of nucleophilic substitution at sp 3 carbon, introductory organic chemistry students must compare and contrast the various attributes and ramifications of S N 2 versus S N 1 reaction pathways. The dramatic (even melodramatic) way in which some students ask such comparative questions inspired a parody of Hamlet's famous to be or not to be soliloquy. Herein, Hamlet (the son of an organic chemist of Denmark) is the surrogate of any and every student as he uses a thoroughly Shakespearian approach to sorting out some of the key distinguishing features of S N 2 versus S N 1 reactions.

    Androgens are crucial for normal testicular descent. Studies show that some pesticides have estrogenic or antiandrogenic effects, and that female workers exposed to pesticides have increased risk of having a boy with cryptorchidism. The main objective of the present study was to investigate whether pregnant women exposed to pesticides due to their work in horticulture experience excess risk of having sons with cryptorchidism. We conducted a cohort study of pregnant women working in horticulture using four cohorts including one cohort established with data from the departments of occupational medicine in Jutland and Funen and three existing mother-child cohorts (n=1,468). A reference group was established from the entire Danish population of boys born in the period of 1986-2007 (n=783,817). Nationwide Danish health registers provided information on birth outcome, cryptorchidism diagnosis and orchiopexy. The level of occupational exposure to pesticides was assessed by expert judgment blinded towards outcome status. Risk of cryptorchidism among exposed horticulture workers compared to the background population and to unexposed horticulture workers was assessed by Cox regression models. Pesticide exposed women employed in horticulture had a hazard ratio (HR) of having cryptorchid sons of 1.39 (95% CI 0.84; 2.31) and a HR of orchiopexy of 1.34 (0.72; 2.49) compared to the background population. Analysis divided into separate cohorts revealed a significantly increased risk of cryptorchidism in cohort 2: HR 2.58 (1.07;6.20) and increased risk of orchiopexy in cohort 4: HR 2.76 (1.03;7.35), but no significant associations in the other cohorts. Compared to unexposed women working in horticulture, pesticide exposed women had a risk of having sons with cryptorchidism of 1.34 (0.30; 5.96) and of orchiopexy of 1.93 (0.24;15.4). The data are compatible with a slightly increased risk of cryptorchidism in sons of women exposed to pesticides by working in horticulture.

    Full Text Available David Herbert Lawrence portrays a complex husband-wife, mother-son, and man-woman relationship in his novel Sons and Lovers. This article studied the relational motifs of the major character Paul Morel with other characters and the dire upshot resulting from this relation. The study found that Paul strove for happiness through the concerted entertainment of body and soul with his beloved people, but he failed because his mother’s unusual attachment to him negatively impacted on his building up a normal relation with others. Mother’s failure to find happiness in her conjugal life led her to pouring her love into Paul, exploiting him, making him sub-serve her own need and denying him the right to his own independent life. As a result, the son’s relation with other women proved a disastrous failure. The women with whom Paul had relation underwent part of the sufferings somehow or other. Finally, Mother’s death made him hopeless and left his life in nothingness.

    Full Text Available DOI:10.17014/ijog.3.2.127-137The Nam Con Son Basin covering an area of circa 110,000 km2 is characterized by complex tectonic settings of the basin which has not fully been understood. Multiple faults allowed favourable migration passageways for hydrocarbons to go in and out of traps. Despite a large amount of newly acquired seismic and well data there is no significant update on the tectonic evolution and history of the basin development. In this study, the vast amount of seismic and well data were integrated and reinterpreted to define the key structural events in the Nam Con Son Basin. The results show that the basin has undergone two extentional phases. The first N - S extensional phase terminated at around 30 M.a. forming E - W trending grabens which are complicated by multiple half grabens filled by Lower Oligocene sediments. These grabens were reactivated during the second NW - SE extension (Middle Miocene, that resulted from the progressive propagation of NE-SW listric fault from the middle part of the grabens to the margins, and the large scale building up of roll-over structure. Further to the SW, the faults of the second extentional phase turn to NNE-SSW and ultimately N - S in the SW edge of the basin. Most of the fault systems were inactive by Upper Miocene except for the N - S fault system which is still active until recent time.

  6. A Stylistic Analysis of D.H. Lawrence’s ‘Sons and Lovers’

    Nozar Niazi

    2013-05-01

    Full Text Available This paper aims at analyzing D.H. Lawrence’s ‘Sons and Lovers’ using a stylistic approach. Stylistics is a study of the amalgamation of form with content. The stylistic analysis of a novel goes beyond the traditional, intuitive interpretation, because it combines intuition and detailed linguistic analysis of the text. The defining elements of modern language are within the text itself, not prescribed from outside. With modernist texts, usually understanding comes from close study of the language system defined within the text itself. Form, technique and style are considered not as a mere vehicle of the content of the story, but an integral part of the work’s meaning and value. In our analysis of ‘Sons and Lovers’ the resources of language: lexis, syntax, phonology, figurative language, cohesion and coherence, are discussed in relation to the style of discourse in order to explore hidden meanings in the text. The resources of language are shown to be an essential part of the meaning of the novel.

  7. Cinematic narratives of Sonderkommando: Son of saul or narrating the victim, perpetrator, trauma and death

    Directory of Open Access Journals (Sweden)

    Daković Nevena

    2016-01-01

    Full Text Available The aim of this paper is to map out - by analysing the film Son of Saul, but also by its comparison with two other films dealing with the topic, Himmelkommando and The Grey Zone, the narrative mechanism that satisfies the complex ethical and aesthetical demands imposed by the theme of Sonderkommando as the particular episode of the Holocaust. The key element of the narrative structure is the construction of the Levi’s “dead and drowned” witness who “resurrected” through the narrative intervention becomes the only reliable and credible narrator of the historical trauma. The prerequisite for his emergence is the narration and representation of the death which makes but also solves the traumatised - understood as multiple, fragmented, opposed - identities of the members of the special squad. Their entangled identity involves the simultaneous presence of a victim, perpetrator, witness and the authentic narrator of the trauma of the death camp. The death of the perpetrator is the condition sina qua non for the emergence of the figure of the victim-witness narrator but also for making of narrative which overcomes the initial trauma of the Holocaust. The detailed analysis of the film Son of Saul confirms and identifies these narratives as the modernist narration of the post-traumatic film.

    2012-06-01

    There is growing evidence in China that son preference is on the decline, but the sex ratio at birth is still the highest in the world at around 120 male births to 100 females. The aim of the study was to explore attitudes towards gender preference among people of reproductive age, to determine the reasons why the sex ratio is persistently high, and to inform policy options. We conducted in-depth interviews with 212 individuals who aged from 18 to 39 in rural and urban areas of three provinces: Yunnan, Guizhou and Zhejiang. We show that while son preference has weakened considerably, it has not disappeared. The sex ratio remains high, because of this small minority of individuals, who still choose sex-selective abortion to ensure male offsprings. Intensive local policy interventions have been successful in reducing the sex ratio in some areas and these should be disseminated widely. In addition, the law forbidding sex selection should be actively enforced, and the One Child Policy should be relaxed in some areas, to reduce the disproportionately high sex ratio in the second order births.

    Full Text Available The unambiguous detection of individual solar internal g modes continues to elude us. With the aid of new additions to calibration procedures, as well as updated methods to combine multi-site time series more effectively, the noise and signal detection threshold levels in the low-frequency domain (where the g modes are expected to be found have been greatly improved. In the BiSON 23-year dataset these levels now rival those of GOLF, and with much greater frequency resolution available, due to the long time series, there is an opportunity to place more constraints on the upper limits of individual g mode amplitudes. Here we detail recent work dedicated to the challenges of observing low-frequency oscillations using a ground-based network, including the role of the window function as well as the effect of calibration on the low frequency domain.

    Science.gov (United States)

    Allen, Holly

    2017-03-01

    Sensationalized representations of autistic families in film and other media frequently feature violent encounters between mothers and sons. This essay analyzes two media stories and three films that suggest how limited-and therefore misleading-popular representations of the autism family are. Except for one of the films, these representations blame the problem of adult autistic dependency on either monstrous autism or bad mothering. Doing so elides collective social responsibility for autism care and denies the reality that autistic adults continue to have complex dependency needs that families cannot always meet. Narratives that sensationalize youth and adults with autism or scapegoat their maternal caregivers also diminish opportunities for social inclusion and for autistic people to live fully and dependently.

    Debris discs are evidence of the ongoing destructive collisions between planetesimals, and their presence around stars also suggests that planets exist in these systems. In this paper, we present submillimetre images of the thermal emission from debris discs that formed the SCUBA-2 Observations of Nearby Stars (SONS) survey, one of seven legacy surveys undertaken on the James Clerk Maxwell Telescope between 2012 and 2015. The overall results of the survey are presented in the form of 850 μm (and 450 μm, where possible) images and fluxes for the observed fields. Excess thermal emission, over that expected from the stellar photosphere, is detected around 49 stars out of the 100 observed fields. The discs are characterized in terms of their flux density, size (radial distribution of the dust) and derived dust properties from their spectral energy distributions. The results show discs over a range of sizes, typically 1-10 times the diameter of the Edgeworth-Kuiper Belt in our Solar system. The mass of a disc, for particles up to a few millimetres in size, is uniquely obtainable with submillimetre observations and this quantity is presented as a function of the host stars' age, showing a tentative decline in mass with age. Having doubled the number of imaged discs at submillimetre wavelengths from ground-based, single-dish telescope observations, one of the key legacy products from the SONS survey is to provide a comprehensive target list to observe at high angular resolution using submillimetre/millimetre interferometers (e.g. Atacama Large Millimeter Array, Smithsonian Millimeter Array).

    Full Text Available Bande-Son, de Bertrand de la Peine, fait défiler trois figures de l’artiste qui suggèrent pour l’activité artistique un domaine de définition. À la pointe de la contemporanéité, Sven Langhens est un acousticien qui s’attache à rendre audible le chant de l’infime, celui des bêtes minuscules et même celui des pierres. Avant lui, au XVIIIe siècle, Rudolf Erich Raspe, auteur des Aventures du baron de Munchhausen, s’était déjà lancé sur les traces de pierres chantantes. Enfin, légèrement en retrait par rapport à ces deux figures originales dont il orchestre les rapports, le narrateur propose une poétique reflétant et court-circuitant à la fois les recherches de ses deux personnages. Leur interaction culminera dans une installation en Provence, qui, transcendant la distinction entre les différents sujets de l’art et leur objet, parviendra à piéger dans un miroir la force du vent.Bertrand de la Peine Bande-Son scrolls three artist figures who suggest a domain of definition for artistic activity. At the forefront of the contemporary, Sven Langhens is an acoustician who strives to make audible the voice of the tiny, tiny animals and even the stones. Before him, in the eighteenth century, Rudolf Erich Raspe, author of The Surprising Adventures of Baron Munchausen, had already run on the footsteps of singing stones. Finally, slightly down compared to the two original figures, the narrator reports their relationships and offers a poetic reflecting and bypassing his characters research. Their interaction will culminate in an installation in Provence, which transcends the distinction between the different subjects of art and object, succeeding in trapping the wind by a mirror’s force.

    To distinguish the origins of higher weight status and determine when and why intra- and interracial/ethnic disparities emerge. The study used a longitudinal analysis of the Early Childhood Longitudinal Study-Birth Cohort (ECLS-B). The study was conducted in the United States. Participants were children of non-Hispanic white mothers and children of U.S.- and foreign-born mothers of Mexican origin from a nationally representative sample of children born in the year 2001 (N ≈ 3700). The Centers for Disease Control and Prevention growth charts determined sex- and age-specific weight status. Covariates were obtained from birth certificate records and parent interviews. Frequencies, growth curve trajectories, and ordinary least squares regression examined body mass index (BMI) and obesity across survey waves. Compared to their peers with non-Hispanic white mothers, children of Mexican-heritage mothers have higher average BMI and greater rates of obesity. The BMI of boys with Mexican-born mothers is higher relative to whites and children of U.S.-born Mexican mothers across early childhood, increasing sharply at about age 4.5 years. This divergence is driven by increases in the BMI of boys, as girls do not show the same growth. A number of measures, including descriptors of children's nutritional intake, lifestyle factors, and acculturation, do not explain the increased obesity rates among sons of Mexican mothers. Despite favorable perinatal health and weight, Mexican-American sons of foreign-born mothers show disadvantages in BMI that emerge close to the start of kindergarten. © 2016 by American Journal of Health Promotion, Inc.

    Coercive parent-child interaction models posit that an escalating cycle of negative, bidirectional interchanges influences the development of boys' externalizing problems and caregivers' maladaptive parenting over time. However, longitudinal studies examining this hypothesis have been unable to rule out the possibility that between-individual factors account for bidirectional associations between child externalizing problems and maladaptive parenting. Using a longitudinal sample of boys (N = 503) repeatedly assessed eight times across 6-month intervals in childhood (in a range between 6 and 13 years), the current study is the first to use novel within-individual change (fixed effects) models to examine whether parents tend to increase their use of maladaptive parenting strategies following an increase in their son's externalizing problems, or vice versa. These bidirectional associations were examined using multiple facets of externalizing problems (i.e., interpersonal callousness, conduct and oppositional defiant problems, hyperactivity/impulsivity) and parenting behaviors (i.e., physical punishment, involvement, parent-child communication). Analyses failed to support the notion that when boys increase their typical level of problem behaviors, their parents show an increase in their typical level of maladaptive parenting across the subsequent 6 month period, and vice versa. Instead, across 6-month intervals, within parent-son dyads, changes in maladaptive parenting and child externalizing problems waxed and waned in concert. Fixed effects models to address the topic of bidirectional relations between parent and child behavior are severely underrepresented. We recommend that other researchers who have found significant bidirectional parent-child associations using rank-order change models reexamine their data to determine whether these findings hold when examining changes within parent-child dyads.

    L'objectif de ce projet etait de developper un outil de controle en temps reel du temps de compaction en se servant du son genere par le vibrocompacteur pendant le formage des anodes crues. Ainsi, une application a ete developpee pour l'analyse des sons enregistres. Des essais ont ete realises avec differents microphones pour une meilleure qualite des mesures et un a ete choisi pour la suite du projet. De meme, differents tests ont ete realises sur des anodes de laboratoire ainsi que des anodes a l'echelle industrielle afin de mettre en place une methode pour la detection du temps optimal necessaire au formage des anodes. Les travaux au laboratoire de carbone a l'Universite du Quebec a Chicoutimi (UQAC) ont consiste a l'enregistrement de son des anodes fabriquees sur place avec differentes configurations; et a la caracterisation de certaines anodes de l'usine. Les anodes fabriquees au laboratoire sont reparties en deux groupes. Le premier regroupe les anodes pour la validation de notre methode. Ce sont des anodes produites avec des temps de compaction differents. Le laboratoire de carbone a l'UQAC est unique et il est possible de produire des anodes avec les memes proprietes que celles des anodes industrielles. Par consequent, la validation initialement prevue a l'usine a ete effectuee avec les anodes de laboratoire. Le deuxieme groupe a servi a etudier les effets des matieres premieres sur le temps de compaction. Le type de coke et le type de brai ont constitue les differentes variations dans ce deuxieme groupe. Quant aux tests et mesures a l'usine, ils ont ete realises en trois campagnes de mesure. La premiere campagne en juin 2014 a servi a standardiser et a trouver le meilleur positionnement des appareils pour les mesures, a regler le logiciel et a faire les premieres mesures. Une deuxieme campagne en mai 2015 a fait l'objet d'enregistrement de son en classant les anodes selon differents temps de compaction. La troisieme et derniere campagne en decembre 2015 a

    Full Text Available La pobreza campesina persiste a pesar de los programas de carácter especial que se adelantan desde hace muchos años, tanto por iniciativa de los gobiernos latinoamericanos, como de organismos internacionales. Las fórmulas, las medidas, las estrategias adoptadas hasta ahora para aminorar la pobreza, se enmarcan en un cuadro de soluciones coyunturales o segmentarias, sin un conducto lógico que permita influir positivamente los elementos de un plan global e integral de acción. Son programas de crédito individual para la producción, pero sin estrategias de comercialización. Otros son de capacitación y educación, pero desconectados de la realidad económica que envuelve los campesinos. En el presente ensayo, se busca formular una estrategia de carácter estructural, analizando el conjunto de las relaciones económicas del complejo rural, escenario donde actúan todos los agentes responsables de la producción agrícola desde la siembra hasta el consumo. Se analizan las causas estructurales de la riqueza, los puntos de acumulación o agregados y su capacidad de generar y retener los valores que se van creando alrededor del producto, y su expresión corno centros de decisión de precios, de políticas económicas y de reinversión de los excedentes producidos. Se examinan la mecánica de la transferencia de valores de un agregado a otro y los elementos de decisión de cada punto de acumulación. Se recogen algunas inquietudes del poco éxito de los programas de desarrollo rural y se reafirma la convicción de que los campesinos pueden llegar a ser ricos, sin miedo de emplear este término, siempre y cuando el gobierno y la sociedad civil se decidan a tornar medidas integrales capaces de erradicar las causas de la pobreza. En otras palabras, introducir la actividad campesina en las estructuras de riqueza, a través de empresas asociativas planificadas para administrar el complejo económico rural.

    Full Text Available The imaginary and sinister concentration-camp chief Otto Friedrich Zur Linde was conceived by Jorge-Luis Borges as an example of misunderstanding philosophy and life, by seeing in them only the power of fight. This conception is compared with a dynamic understanding of philosophy. For Mr. Zur Linde Aristotle and Plato represent this confrontation, and each philosophical debate in history could be considered as a moment in it. But now, in the last fight, the will to power of man has gone beyond all the limits, even of morality. However some modern techniques of appropriation of ancient philosophy are completely opposed to this conception, namely Paul Ricoeur’s theory of fiction and Heidegger’s Sein und Schein,. Ultimately, the close relationship between poetry and philosophy since its origins speak against this thesis. A closer analysis of Nietzsche and Hölderlin will help to enlighten how wrong Zur Linde´s conception is..El siniestro jefe de un campo de concentración Otto Friedrich Zur Linde, concebido por Borges como ejemplo de una interpretación de la filosofía y la vida en la que la lucha es el único motor, es confrontado con una concepción de la filosofía dinámica. Zur Linde mantiene que Aristóteles y Platón son el enfrentamiento filosófico paradigmático. En el último momento del enfrentamiento la voluntad de poder de un nuevo superhombre ha rebasado todos los límites, incluso el de la conciencia. A esto se oponen las técnicas de apropiación filosófica del mundo griego por parte de la modernidad, a saber: el poder de la ficción, el Schein y el Sein así como el nacimiento de la filosofía, tan cercano a la poesía. Bajo este prisma cabe un análisis de Nietzsche y Hölderlin, que reniega de la interpretación de Zur Linde y clarifica que ante todo poetas y filósofos son seres de palabra.

    Full Text Available Background: The theory of attachment is important to understand a lot of human behaviour. Styles of attachment could be important predictors in developing dependence on alcoholism. Insecure attachment patterns could be significant risk factors for future alcohol use. Methods: Participants for this study consist of fathers with alcohol dependence syndrome (ADS from treatment centres and fathers from the community with no dependency on alcohol, and their sons (n=200. The Michigan Alcoholism Screening Test (MAST, socioeconomic status scale were administered, and attachment styles were derived by the Attachment Style Questionnaire (ASQ. We hypothesised a prior concept reflecting theoretical predictions for the association between attachment styles and alcohol in both the generations. Results: Statistics on SPSS-16 was used to test our hypotheses. As predicted, fathers with ADS had insecure attachments styles in comparison to the control group. Substance abuse/dependence and treatment participation were at an all-time low for the secure group. Conclusion: The findings from this study identify attachment styles as an influential factor in understanding the divergence between alcohol dependence in treatment seekers. The findings further imply that differential treatment may need to be provided taking into account one’s attachment representation to promote successful recovery. It also highlights the need to develop secure ties in children of alcoholic parents to protect them from use of substances as a coping and a learned mechanism. Limitations of the study and suggestions for further research are highlighted and implications for diagnosis and treatment are discussed.

  13. Between dad and son: initiating, delivering, and assimilating bad cancer news.

    2002-01-01

    The opening moments of a phone call reveal how a father informs his son, for the 1st time, that his mom's tumor is malignant. An extended phone opening reveals how delaying talk about the mom's condition allows for important interactional work: Displaying resistance to announce the bad news directly, projecting and anticipating the valence of forthcoming news prior to its announcement, and delicately sharing ownership of a serious health condition at the outset of a family cancer journey. Enacting a biomedical demeanor, replete with technical language and withholdings of emotional and personal reactions, subsequent delivery and reception of the bad news is managed stoically-a normalized resource employed by consequential figures when managing and coping with dreaded news events. By closely examining how family members talk through cancer on the telephone, the scope of health communication research is extended beyond clinical settings into home environments, progress is made on the noticeable absence of interactional studies in psycho-oncology, and diverse implications arise for understanding how lay persons diagnose and manage illness dilemmas.

    Human immunodeficiency virus (HIV) is increasing in Thai youth. Consequently, a school-based National Condom Strategy program was launched in 2015 to reduce the rate of HIV and sexually transmitted infections. We conducted in-depth interviews of 31 parents/adoptive guardians of high-school age Thai boys to explore parents' knowledge, attitudes, behaviors, and barriers to promoting condom use and its role in preventing HIV/sexually transmitted infections. A descriptive phenomenological approach and thematic analysis was used. Most participants had knowledge and positive attitudes about condom use. Half disagreed with the National Condom Strategy of placing condom vending machines in schools. More than half did not initiate teaching male youth about condom use until the youth had broached the question or only intended to do so when the youths were older. Barriers included parents' lack of condom experience and knowledge, embarrassment/discomfort when talking about condoms, and belief that youth were not sexually active. Parents are a key factor for supporting condom use in Thailand. This study supports the need for education programs for parents. © 2017 John Wiley & Sons Australia, Ltd.

  15. A Novel Stochastic Learning Automata Based SON Interference Mitigation Framework for 5G HetNets

    2016-12-01

    Full Text Available Long Term Evolution Advanced (LTE-A Heterogeneous Networks (HetNet are an important aspect of 5th generation mobile communication systems. They consists of high power macrocells along with low power cells i.e. picocells and femtocells to fill up macrocell coverage gaps. HetNet permit deployment of femtocells by users for added flexibility, but then interference issues between neighbouring cells have to be addressed as all femtocells use the same frequency channels for transmission. To mitigate this problem, LTE-A standard offers two new features, one is carrier aggregation in which Component Carriers (CC form the basic aggregate units shared among cells and the other is enhanced Inter-Cell Interference Co-ordination (eICIC through X2 interface. The physical implementation of these features is left open to research. This paper investigates two distinct techniques for orthogonal CC selection through Stochastic Cellular Learning Automata (SCLA to improve the QoS performance of a femtocell. The first, technique uses SCLA with user feedback, and the second technique uses SCLA with a central publishing server where all cells upload their past used CC vectors. SCLA methods are better suited for Self Organizing Network (SON as they do not require synchronized cell coordination, have low complexity and have good optimization characteristics. The simulation results show that the techniques enhance the cell edge performance considerably.

    Mothers with a history of child sexual abuse report less warmth toward their children, but whether this association differs by child gender is unknown. We examined the association of maternal child sexual abuse and warmth across child gender, accounting for depression, post-traumatic stress disorder, and child physical abuse. We verbally administered self-report measures to a cross-sectional sample of 154 mothers with a child between 8 and 12 years old. Eighty-five mothers based warmth responses on a son, and 69 on a daughter. We conducted a hierarchical multiple regression, including child gender, maternal child sexual abuse, child physical abuse, depression, post-traumatic stress disorder, and 4 two-way interaction terms with child gender. Maternal depression predicted decreased warmth, regardless of child gender, and maternal child sexual abuse predicted decreased warmth, but only toward daughters. Given previous research suggesting that maternal warmth predicts child well-being, the current finding may represent an important avenue of intergenerational transmission of risk in girls.

  18. Behavioral problems in sons of incarcerated or otherwise absent fathers: the issue of separation.

    Science.gov (United States)

    Gabel, S

    1992-09-01

    The decade of the 1980s witnessed more than a doubling in the number of incarcerated individuals. Little is known about the psychological reactions of children whose parents are incarcerated, although a variety of behavioral disorders apparently related to separation, stigma, and deception of the child has been reported. The possibility of aggressive or antisocial behavior emerging in sons of incarcerated fathers has been mentioned as of particular concern in some reports. This article discusses salient themes in the literature on the reactions of children to parental incarceration, with an emphasis on boys' reactions to incarceration of their fathers. It critiques this literature and compares the findings with literature on the effects of separation in father absence related to other causes (for example, divorce, death, military service). Behavioral or emotional disorder associated with paternal incarceration probably is related mainly to associated factors such as the meaning of the incarceration to the child, the remaining caretaker's psychological characteristics and psychopathology, the parenting relationship between the caretaker and the child, and the coping capacities and resources of the family, rather than to the separation itself. Recommendations for further research in this increasingly important field are provided.

  19. Polyandrous females benefit by producing sons that achieve high reproductive success in a competitive environment.

    2011-09-22

    Females of many taxa often copulate with multiple males and incite sperm competition. On the premise that males of high genetic quality are more successful in sperm competition, it has been suggested that females may benefit from polyandry by accruing 'good genes' for their offspring. Laboratory studies have shown that multiple mating can increase female fitness through enhanced embryo viability, and have exposed how polyandry influences the evolution of the ejaculate. However, such studies often do not allow for both female mate choice and male-male competition to operate simultaneously. Here, I took house mice (Mus domesticus) from selection lines that had been evolving with (polygamous) and without (monogamous) sperm competition for 16 generations and, by placing them in free-ranging enclosures for 11 weeks, forced them to compete for access to resources and mates. Parentage analyses revealed that female reproductive success was not influenced by selection history, but there was a significant paternity bias towards males from the polygamous selection lines. Therefore, I show that female house mice benefit from polyandry by producing sons that achieve increased fitness in a semi-natural environment. This journal is © 2011 The Royal Society

    Full Text Available Men have long been associated with dominance, strength and confidence and the issue regarding being compliant to the acceptable masculine ideal has always been part of a culture’s social identity. This study focuses on the critical discussion on masculinity studies in the classic fiction of D.H Lawrence.  Drawing on narrative data from his novel Sons and Lovers (1913, the study examines how hegemonic masculinity is conformed by the male protagonist, Walter Morel, in his gendered relationship. More specifically, the analysis focuses on how the male character aligns himself with the hegemonically authoritarian philosophy of ‘tough’ masculinity. The effects of social practices and socio-historical context in which Lawrence wrote these novels are also examined. The study utilises Connell’s theory of hegemonic masculinity to explicate Lawrence’s depiction of dominant masculinity through his character. The findings reveal that Lawrence aligns his male protagonist to the dominant role by sanctioning aggressiveness, autonomy and violence.

    Most studies on early childhood parenting include only mothers. Fathers are rarely observed in interaction with their young children, although they play an important role in the socialization of their children. In this study, we observed parenting of mothers and fathers toward their sons and daughters in families with two children, using a within-family approach in a sample with systematically varying family constellations. Participants included 389 families with two children (1 and 3 years of age). Parenting practices were coded during free play using the Emotional Availability Scales (Biringen, 2008). Findings revealed that mothers showed higher levels of sensitivity and lower levels of intrusiveness toward their children than fathers. Furthermore, mothers and fathers were more sensitive and less intrusive toward their oldest child than toward their youngest child. Fathers' higher intrusiveness toward the youngest child was only found in the case of a youngest boy. Child gender was not related to parenting in any of the other analyses. Our results suggest that parent gender is more salient than child gender in the prediction of parenting practices in early childhood. PsycINFO Database Record (c) 2014 APA, all rights reserved.

    Female preferences for specific male phenotypes have been documented across a wide range of animal taxa, including numerous species where males contribute only gametes to offspring production. Yet, selective pressures maintaining such preferences are among the major unknowns of evolutionary biology. Theoretical studies suggest that preferences can evolve if they confer genetic benefits in terms of increased attractiveness of sons ("Fisherian" models) or overall fitness of offspring ("good genes" models). These two types of models predict, respectively, that male attractiveness is heritable and genetically correlated with fitness. In this meta-analysis, we draw general conclusions from over two decades worth of empirical studies testing these predictions (90 studies on 55 species in total). We found evidence for heritability of male attractiveness. However, attractiveness showed no association with traits directly associated with fitness (life-history traits). Interestingly, it did show a positive correlation with physiological traits, which include immunocompetence and condition. In conclusion, our results support "Fisherian" models of preference evolution, while providing equivocal evidence for "good genes." We pinpoint research directions that should stimulate progress in our understanding of the evolution of female choice. © 2012 The Author(s). Evolution© 2012 The Society for the Study of Evolution.

    Previous studies have shown that cardiac microacceleration signals, recorded either cutaneously, or embedded into the tip of an endocardial pacing lead, provide meaningful information to characterize the cardiac mechanical function. This information may be useful to personalize and optimize the cardiac resynchronization therapy, delivered by a biventricular pacemaker, for patients suffering from chronic heart failure (HF). This paper focuses on the improvement of a previously proposed method for the estimation of the systole period from a signal acquired with a cardiac microaccelerometer (SonR sensor, Sorin CRM SAS, France). We propose an optimal algorithm switching approach, to dynamically select the best configuration of the estimation method, as a function of different control variables, such as the signal-to-noise ratio or heart rate. This method was evaluated on a database containing recordings from 31 patients suffering from chronic HF and implanted with a biventricular pacemaker, for which various cardiac pacing configurations were tested. Ultrasound measurements of the systole period were used as a reference and the improved method was compared with the original estimator. A reduction of 11% on the absolute estimation error was obtained for the systole period with the proposed algorithm switching approach.

    The {sup 3}He behavior in the non active R7T7 type borosilicate glass called SON68 has been investigated using the implantation method to introduce helium in the material. Nuclear Reaction Analysis (NRA) was performed to follow the helium concentration depth profile evolution as a function of annealing time and temperature. In addition, in situ Transmission Electron Microscopy (TEM) has been implemented to study the formation of helium bubbles during both implantation and annealing processes. Numerical modeling with two different approaches is proposed and discussed to investigate the helium mobility mechanisms. Our study reveals for helium incorporation by implantation at low temperature the presence of several helium populations with disparate diffusivities. The most mobile helium fraction would be attributed to atomic diffusion. The corresponding activation energy value (0.61 eV) extracted from Arrhenius graphs is in good agreement with literature data. The results also highlight that the damages associated to helium sursaturation are the source of small helium clusters formation, with a reduced mobility instead of the atomic mobility measured by the infusion technique. Small cavities that support this assumption have been observed by TEM at low temperature.

    Mothers with a history of child sexual abuse report less warmth toward their children, but whether this association differs by child gender is unknown. We examined the association of maternal child sexual abuse and warmth across child gender, accounting for depression, post-traumatic stress disorder, and child physical abuse. We verbally administered self-report measures to a cross-sectional sample of 154 mothers with a child between 8 and 12 years old. Eighty-five mothers based warmth responses on a son, and 69 on a daughter. We conducted a hierarchical multiple regression, including child gender, maternal child sexual abuse, child physical abuse, depression, post-traumatic stress disorder, and 4 two-way interaction terms with child gender. Maternal depression predicted decreased warmth, regardless of child gender, and maternal child sexual abuse predicted decreased warmth, but only toward daughters. Given previous research suggesting that maternal warmth predicts child well-being, the current finding may represent an important avenue of intergenerational transmission of risk in girls.

    Full Text Available The winner of many prestigious prizes (Oscar for the best foreign language film, Grand Prize of the Cannes Film Festival, and the Golden Globe among them, the Hungarian film, Son of Saul – according to most critics – represents the Holocaust trauma in a completely new and intriguing way. The filmmakers have invented a special form in order to tackle the heroic task of showing the unwatchable, representing the unthinkable. In this essay I analyse the representational strategy of the film from a phenomenological point of view, and position it in the theoretical framework of haptic sensuality formulated by Vivian Sobchack and Laura U. Marks, among others. I mainly focus on the use of sound, in particular the role of sound design in the creation of haptic space. With the help of the analysis of the representation and artistic invocation of the different bodily senses in the film, I demonstrate how traditional artistic formal elements (characteristic of highly artistic, even experimental productions are combined with high impact effects often present in popular film forms. I argue that the successful combination of these two factors makes the film an example of artistic immersive cinema.1

    Full Text Available A siete mil kilómetros de su metrópoli, Francia, Guadalupe mantiene relaciones con ella más que con su entorno Caribe, y esto se debe a su colonización en el siglo XVII hasta principios de 1970. Durante este tiempo, la dependencia económica y comercial con Francia se fortalece mientras que la sensación de ser francés es cada vez más compartida por su gente. Los ingresos solo están basados en el monocultivo de caña de azúcar. Las corporaciones metropolitanas tienen plantaciones que producen un azúcar crudo para exportar a las refinerías en Francia. Sus directores y ejecutivos son metropolitanos, y a través de ellos es que la gente percibe lo que es Francia. Se espera la diversificación de las actividades económicas locales al cierre de las plantaciones azucareras, para traer una apertura hacia el Caribe en un futuro próximo. Es el propósito de este trabajo demostrar por qué este proceso has sido tan retardado.

  11. Were king Stefan the First-Crowned and his son Radoslav co-rulers?

    Full Text Available The Serbian historiography considers the issue of the co-ruling of King Stefan the First-Crowned and his son Radoslav as the one finally resolved. The suggested solution on the co-rule of Stefan and Radoslav may be most succinctly expressed as following: as early as in the year of 1220, due to the frail health of Stefan the First-Crowned and Radoslav's marriage to Anne the Epirus princess, Radoslav was crowned to be the king and positioned to co-rule with his father after the Byzantine model of governing. Nevertheless this point of view has some loose ends. The notion of co-ruling and the very term of 'co-ruler' are quite freely used in the scholarly works. A general consensus on the precise meaning has not been reached yet. At the point where one author perceives a co-rule, the other categorically denies it. Basically the approach equalizing the heir to the throne and the co-ruler is wrong. Although the co-rulers in most cases were the throne heirs, they cannot be called the co-rulers because of the right to inherit the throne, but for the ruling attributes that formally established that right. The conviction of the co-rule of King Stefan and his son Radoslav is founded on the interpretation of the facts coming from the following sources: entitling charters for the monastery of Žiča, produced by Stefan and Radoslav around 1220; some segments from St. Sava's biographies by Domentian and Theodosius describing the circumstances of Stefan's death-bed leaving the throne to Radoslav; the three acts of the town of Kotor from 1221 and 1227 dated by the rule of king Radoslav, the portraits of Stefan and Radoslav next to the entrance to the Church of the Ascension in the monastery of Žiča and in the nartex of the Mileševa monastery church. In the first Žiča charter, Stefan calls Radoslav his heir, while in the second Žiča charter Stefan points out Radoslav as his first-born son blessed by him to be the king of the whole state.

    South Korea was among the first countries to report both an abnormally high sex ratio at birth (SRB) and its subsequent normalization. We examine the role of son preference in driving fertility intentions during a period of declining SRB and consider the contribution of individual characteristics and broader social context to explaining changes in intentions. We employ data from the National Survey on Fertility, Family Health and Welfare that span 1991-2012. We find that reported son preference declined to a great extent but remained substantial by the end of the observation period, and that the intention to have a third child still differed by sex of existing children. Change in individual-level factors does not explain the decline in son preference, suggesting that broad social changes were also important. This study provides a better understanding of how son preference evolves in the post-transitional context of very low fertility.

    Full Text Available Abstract Background In the Netherlands, youths of Moroccan origin account for a disproportionately large percentage of the population in juvenile justice institutions. Previous research showed that Moroccan adolescents in pre-trial arrest are characterized by less serious offending behavior (i.e., primarily property-based and lower levels of mental health problems than native Dutch adolescents in pre-trial arrest. To date, little is known about the parent-child relationship of these adolescents. This study examines the mother-son relationships of Moroccan and native Dutch delinquent adolescents and their association with adolescent delinquency. Methods In the present study, differences in the mother-son relationship characteristics between families of incarcerated (N = 129 and non-incarcerated (N = 324 adolescents were examined, and it was analyzed if these differences between incarcerated and non-incarcerated adolescents were the same for Moroccans and native Dutch. Data collection for the incarcerated sample took place from 2006 to 2008. Comparison data were used of interviews conducted with mothers originating from former larger studies in the general Dutch population. Latent Class Analysis was performed in order to identify types of mother-son relationship. Logistic regression analyses were used to identify the relationships between mother-son relationship types, incarceration and ethnicity. Results A three class model of mother-son relationship types was found: a low-conflict mother-son relationship type, a high-conflict mother-son relationship type, and a neglectful mother-son relationship type. Compared to the native Dutch adolescents, Moroccans (both in the incarcerated and non-incarcerated population more often showed a neglectful mother-son relationship type. For Moroccans, no differences in mother-son relationship types were found between the incarcerated and non-incarcerated adolescents, whereas considerable differences occurred

    Full Text Available This paper attempts to explain parental son preferences among historical Muslim population in the Sandžak region, southwestern Serbia. The paper draws upon data collected in the course of anthropological fieldwork studies in the region. The fieldwork was performed among Muslim and Christian families in Serbian rural area of Sandžak, measuring maternal fitness in relation to several variables. The data set comes from 120 women born between 1880-1924, representing so a historical demographic data based on individual and lineage records. These data were complemented with official records from Archive of Novi Pazar, whenever possible. In this Serbian rural area, land is still considered as an abundant resource, useful in establishing a family, livestock or agriculture. In the past, in spite of yearly fluctuations in production, lands and labor constituted a stable source of wealth from generation to generation. In this study, the data include the socio-economic status of each woman, assigned according to her husband’s family economic status: land-ownership vs. landless. This represents differences in resource availability in terms of nutrition, wealth and workload among these women. As the results show, the Muslim families, on average, left more surviving descendants through sons, in contrast with their Christian counterparts. The basic research question, then, is why? Furthermore, what were the impacts of particular behaviors on reproductive and lineage success, under particular social and ecological conditions? In this sample, regarding the Muslim families, the family structure was/is traditional and stratified, characterized by a large disparity in the status of males and females. Patrilineal inheritance, the concentration of wealth and power in males and the social restriction of women all characterize even today this patriarchal family arrangement. This supports the Trivers-Willard hypothesis, especially in terms of sex-biased parental

  19. Empirical evidence for son-killing X chromosomes and the operation of SA-zygotic drive.

    Directory of Open Access Journals (Sweden)

    Urban Friberg

    Full Text Available Diploid organisms have two copies of all genes, but only one is carried by each haploid gamete and diploid offspring. This causes a fundamental genetic conflict over transmission rate between alternative alleles. Single genes, or gene clusters, only rarely code for the complex phenotypes needed to give them a transmission advantage (drive phenotype. However, all genes on a male's X and Y chromosomes co-segregate, allowing different sex-linked genes to code for different parts of the drive phenotype. Correspondingly, the well-characterized phenomenon of male gametic drive, occurring during haploid gametogenesis, is especially common on sex chromosomes. The new theory of sexually antagonistic zygotic drive of the sex chromosomes (SA-zygotic drive extends the logic of gametic drive into the diploid phase of the lifecycle, whenever there is competition among siblings or harmful sib-sib mating. The X and Y are predicted to gain a transmission advantage by harming offspring of the sex that does not carry them.Here we analyzed a mutant X-chromosome in Drosophila simulans that produced an excess of daughters when transmitted from males. We developed a series of tests to differentiate between gametic and SA-zygotic drive, and provide multiple lines of evidence that SA-zygotic drive is responsible for the sex ratio bias. Driving sires produce about 50% more surviving daughters than sons.Sex-ratio distortion due to genetic conflict has evolved via gametic drive and maternally transmitted endosymbionts. Our data indicate that sex chromosomes can also drive by harming the non-carrier sex of offspring.

  20. Biological effect of Acidithiobacillus thiooxidans on some potentially toxic elements during alteration of SON 68 nuclear glass

    Although underground nuclear waste repositories are not expected to be favourable places for microbial activity, one should not exclude localized action of extremophilic bacteria on some materials involved in the storage concept. Among endogenous or accidentally introduced acidophiles, some are susceptible to lead to a locally drastic decreased in pH, with potential consequences on materials corrosion. Experiments were performed with Acidithiobacillus thiooxidans on 100-125 m french reference nuclear glass SON68 grains in a mineral medium under static conditions during 60 days at 25degC. Growth medium was periodically renewed and analyzed by ICP-AES and ICP-MS spectrometry for both major, trace and ultra-trace elements. Biofilm formation was evidenced by confocal laser microscopy, staining DNA with ethidium bromide and exopolysaccharides with calcofluor white. Biofilm thickness around material grains exceeded 20 m under the chosen experimental conditions. It can be noticed that while numerous studies on biofilm formation upon interaction between Acidithiobacillus ferrooxidans and materials are found in the literature, evidence for biofilm formation is still scarce for the case of the acidophilic bacterium A. thiooxidans. Presence of biofilm is a key parameter for material alteration at the solid/solution interface in biotic systems. Indeed, various constitutive elements of materials trapped in the polyanionic polymer of biofilm may also influence the alteration process. In particular, biofilm may reduce the alteration rate of materials by forming a protective barrier at their surface (Aouad et al., 2008). In this study, glass alteration rates, determined using strontium as tracer, showed that the progressive formation of a biofilm on the surface of glass has a protective effect against its alteration. Uranium and rare earth elements (REE) are efficiently trapped in the biogenic compartment of the system (exopolysaccharides + bacterial cells). Besides, the ratio

    Full Text Available In the last few years, there has been a good amount of theoretical work around the concept of social norm. The work of Cristina Bicchieri and Jon Elster has been specially interesting and intense in this field. Although their respective approaches present substantive differences, they both agree in defining social norms in contrast with other related concepts, such as moral norms. Notwithstanding this basic agreement, they disagree when classifying norms of justice. For Bicchieri these are social norms, while Elster’s view is more complex and he classifies different norms of justice in different categories: some are social while others are semi moral o moral. In this paper I focus on the treatment of one specific norm of justice, the norm of egalitarian distribution, which is a social norm for Bichieri but a moral norm from Elster’s view. With the aid of some recent experiments, I conclude that Elster’s view is more promising, at least when analyzing this particular norm.Durante los últimos años, el concepto de norma social ha sido objeto de un intenso trabajo teórico, en el que cabe destacar las aportaciones de Cristina Bicchieri y Jon Elster. Pese a las diferencias de sus respectivos planteamientos, ambos coinciden en definir el concepto por oposición a otro tipo de normas, en especial las morales. Este acuerdo no impide, sin embargo, que clasifiquen las normas de justicia de manera diferente: mientras que para Bicchieri se trata de normas sociales, Elster clasifica distintas normas de justicia en distintas categorías (sociales, cuasi morales y morales.En este trabajo, y con ayuda de algunos experimentos recientes, se analiza el caso de una norma de justicia, la norma de reparto igualitario, y se defiende que, pese a que los experimentos no son concluyentes, hay algunos factores que apuntan a la mayor validez de la teoría de Elster para el tratamiento y la conceptualización de esta norma.

    Full Text Available Utiliser un film, ou toute création culturelle, pour comprendre le social pose un certain nombre de problèmes méthodologiques. Un film n’est pas un « reflet ». Une création, même si elle se place sous le sceau du réalisme, a un rapport très fort mais indirect avec le contexte historique de sa genèse. Elle est le produit de la rencontre d’un contexte, d’un créateur doté d’une idéologie, d’un « habitus », d’un corpus de valeurs, des modes et techniques en vigueur dans le champ de la création au moment de celle-ci et, comme le rappelle Bourdieu, de la stratégie du créateur par rapport à ses collègues/concurrents. Enfin, sans ajouter une note discordante supplémentaire aux théories de la réception, l’œuvre sera perçue de façon différente selon les publics. My Son the Fanatic sera donc perçu comme une œuvre satanique par les fondamentalistes musulmans, mais sans doute aussi chrétiens, comme une bluette charmante par les midinettes au grand cœur qui semblent être le public visé par la présentation publicitaire du film, comme une démonstration de la justesse de leurs thèses par les partisans de l’intégration, mais aussi par les émules de Huntington pour qui le choc des civilisations est inéluctable, enfin comme une manifestation irresponsable d’ « islamophobie » par les nostalgiques des politiques multiculturalistes d’antan. Les aficionados de Hanif Kureishi, auteur de la nouvelle sur laquelle le film est fondé, et scénariste du film lui-même, y retrouveront le plaidoyer pour la liberté individuelle et, en particulier, la liberté sexuelle qu’ils attendent, mais seront un peu surpris par les côtés didactiques, pour employer cet adjectif dans une acception qui déplait aux didacticiens, c'est-à-dire une volonté de démonstration un peu insistante.Using films, or, for that matter, any cultural artefact in order to reach an understanding of social issues raises a number of

  11. The role of God in the father/son relationship during identity formation – a Gestalt theoretical perspective

    2010-07-01

    Full Text Available This article is based on research done within the Afrikaansspeaking community in the area of the Drakenstein Municipality, Western Cape province, South Africa. The focus falls specifically on one concept that was outlined during the research, namely the perceptions of fathers and adolescent sons on identity formation within their relationship as well as the role that God plays. Combined qualitative/quantitative research was conducted with emphasis on semi-structured interviews with fathers (n=4 and adolescent boys (n=4 and an auto-ethnography of the author as the dominant component. The lessdominant quantitative component consisted of questionnaires completed by fathers (n=42 and adolescent boys (n=180. Metatheoretical assumptions and theoretical assumptions as grounding for the male identity are discussed as part of the author’s paradigmatic perspective. Furthermore, empirical findings are discussed and recommendations are made. From the discussions with fathers and their sons it was clear that both fathers and sons have a need to stand in close relationship to each other and to God. It is within this relationship where their identities are formed. However, fathers seemed to be resistant of transferring their beliefs to their sons. Adolescent boys also indicated no need to one day transfer learned behaviour from their fathers to their sons.

  14. From Founding Father to Pious Son: Filiation, Language, and Royal Inheritance in Alfonso X, the Learned

    Directory of Open Access Journals (Sweden)

    Ryan Szpiech

    2015-07-01

    Full Text Available The influence of King Alfonso X of Castile (reg. 1252–1284 has been so wide that modern historians have stressed Alfonso’s foundational role as a ‘father’ of many Castilian cultural institutions and areas of writing, including prose literature, science, the legal code, and vernacular historiography. This paper argues that the modern focus on Alfonso’s foundational, ‘fatherly’ role, while logical in the context of modern literary historiography, is at odds with Alfonso’s own medieval view of himself as a ‘son’ and heir, one who inherited rather than founded cultural institutions. It proposes that a reorientation of Alfonsine studies according to this medieval worldview, one focused less on Alfonso’s innovations and foundations and more on his continuty with and dependance on his forebears, will permit a clearer portrayal of Alfonso’s importance in medieval literary history. To this end, it explores Aflonso’s representation of himself as the ‘son’ of his father, King Fernando III, in the prologues to his scientific translations, in his encomium of his father known as the Setenario, and in song 292 of his Cantigas de Santa María. A reading of these examples is offered as a first step towards the study of filiation and ‘sonship’ in the vast Alfonsine historiographical and legal corpuses.

    2015-06-01

    Leber congenital amaurosis (LCA) is most often an autosomal recessive disorder. We report a father and son with autosomal dominant LCA due to a mutation in the CRX gene. DNA screening using an allele specific assay of 90 of the most common LCA-causing variations in the coding sequences of AIPL1, CEP290, CRB1, CRX, GUCY2D, RDH12 and RPE65 was performed on the father. Automated DNA sequencing of his son examining exon 3 of the CRX gene was subsequently performed. Both father and son have a heterozygous single base pair deletion of an adenine at codon 153 in the coding sequence of the CRX gene resulting in a frameshift mutation. Mutations involving the CRX gene may demonstrate an autosomal dominant inheritance pattern for LCA.

  16. Son preference in the context of fertility decline: limits to new constructions of gender and kinship in Nepal.

    Science.gov (United States)

    Brunson, Jan

    2010-06-01

    This article explores the persistence of son preference in a patrilineal, patrilocal society in the midst of fertility decline. Using survey and ethnographic data from Hindu-caste Nepali families in a semiurban village, I analyze which cultural norms regarding reproduction are questioned by contemporary married couples and which remain intact. Despite modest improvements in gender equality, levels of education, and economic conditions, the practical knowledge that daughters will be lost to other lineages and households pressures couples who might otherwise be willing to invest in daughters to continue procreating until they produce a son. Young mothers, therefore, reluctantly admit to needing a son, revealing a discrepancy between their initially stated reproductive ideals and their ultimate behavior.

  17. Endocardial acceleration (sonR) vs. ultrasound-derived time intervals in recipients of cardiac resynchronization therapy systems.

    Optimization of cardiac resynchronization therapy (CRT) requires the gathering of cardiac functional information. An accurate timing of the phases of the cardiac cycle is key in the optimization process. We compared Doppler echocardiography to an automated system, based on the recording of sonR (formerly endocardial acceleration), in the detection of mitral and aortic valves closures and measurements of the duration of systole and diastole. We prospectively studied, under various conditions of cardiac stimulation, 75 recipients of CRT systems (69% men), whose mean age was 72 ± 9.2 years, left ventricular ejection fraction 35 ± 11%, baseline QRS duration 154 ± 29 ms, and New York Heart Association functional class 3.0 ± 0.7. We simultaneously recorded (i) sonR, detected by a non-invasive piezoelectric micro-accelerometer sensor clipped onto an electrode located in the parasternal region, (b) electrocardiogram, and (c) Doppler audio signals, using a multichannel data acquisition and analysis system. The correlation between timing of mitral and aortic valve closure by sonR vs. Doppler signals was examined by linear regression analysis. Correlation coefficients and the average absolute error were calculated. A concordance in the timing of the mitral (r = 0.86, error = 9.7 ms) and aortic (r = 0.93, error = 9.7 ms) valves closure was observed between the two methods in 94% of patients. Similarly, sonR and the Doppler-derived measurements of systolic (r = 0.85, error = 13.4 ms) and diastolic (r = 0.99, error = 12 ms) interval durations were concordant in 80% of patients. A high concordance was found between sonR and the cardiac ultrasound in the timings of aortic and mitral valve closures and in the estimation of systolic and diastolic intervals durations. These observations suggest that sonR could be used to monitor cardiac function and adaptively optimize CRT systems.

  12. Superb fairy-wren (Malurus cyaneus sons and daughters acquire song elements of mothers and social fathers

    Directory of Open Access Journals (Sweden)

    Christine eEvans

    2016-02-01

    Full Text Available Birdsong is regarded as a classic example of a sexually-selected trait and has been primarily studied in systems with male song. Complex solo female song is emerging from the shadows of overlooked phenomena. In males, rearing conditions affect male song complexity, and males with complex songs are often more successful at mate attraction and territorial defense. Little is known about the ontogeny or function of complex female song. Here we examine song elements in fledgling superb fairy-wrens (Malurus cyaneus in relation to the song elements of adult tutors. Male and female superb fairy-wrens produce solo song year-round to defend a territory. We ask if sons and daughters acquire song elements from sex-specific vocal tutors. We found that sons and daughters produced the song elements of their mothers and social fathers, and that sons and daughters had comparable song element repertoires at age 7-10 weeks. We conclude that sons and daughters increase their song element repertoire when vocally imitating elements from several vocal tutors, and that both sexes acquire elements from male and female vocal tutors in this system.

  13. Literature as an exploration of the phenomenology of schizophrenia: disorder and recovery in Denis Johnson's Jesus' Son.

    Science.gov (United States)

    Hamm, Jay A; Leonhardt, Bethany L; Fogley, Rebecca L; Lysaker, Paul H

    2014-12-01

    When read as a fictional psychosis narrative, Jesus' Son, a collection of short stories by Denis Johnson, reveals important elements of the phenomenology of schizophrenia and recovery. It is possible that Jesus' Son, as a work of fiction, may be able to uniquely add depth and nuance to an understanding of the phenomenology of schizophrenia involving a state of psychological fragmentation, an ever-changing interpersonal field and a loss of personal agency. In addition, by following the protagonist in Jesus' Son as he begins to resolve some of his difficulties, the book also offers an individualised account of recovery. The authors detail how the book reveals these insights about schizophrenia and recovery and suggest that these elements are intertwined in such a manner that leads to a profound disruption of self-experience, characterised by a collapse of metacognitive processes. Jesus' Son may add depth to our understanding of the subjective experience of schizophrenia and recovery, and also may serve as one example in which the study of humanities offers an opportunity to explore the human elements in the most profound forms of suffering.

    Pellegrin, E

    2000-07-01

    This study is a contribution in the understanding of the long time behavior of alteration products of the glass SON 68, used to simulate the nuclear glass R7T7. The local structure around Zirconium and iron has been probed using X-ray absorption spectroscopy in altered surface layer of glass SON 68. Alteration products of this glass have been prepared for short (3 hours to 7 days) and long (17 months) time, using various indexes of saturation for the leaching solution with respect to the Si content of the glass (from 0 to 90 %). The evolution of the local structure around Fe has also been studied in recent and old natural ferric gels. Zr, Fe- L{sub 2,3} XANES and Zr, Fe-K EXAFS spectroscopies have shown that, in the pristine glass, these elements are connected to the polymeric network. Zr is found in an environment close to that of a zircon-silicate containing Na and Ca. Trivalent Fe is a network former. The leached layer of glass SON 68 is constituted of poorly ordered Zr-and Fe-(oxi-hydr)oxides that may have been formed by a mechanism of dissolution/precipitation; a relict phase with the same Zr local structure as that observed in the pristine glass, probably obtained thanks to in-situ solid condensation. The structural characteristics of the leached layer are observed from the first steps of alteration for Zr and Fe. Conversely to Fe, the structural status of Zr depends on the leaching kinetic as well as the contents of Ca and Si in the solid. Fe-K EXAFS results in recent natural ferri-hydrides present a clear structural similarity with that determined in glass SON 68 leached products. The study of old paleosols (between 1,800 and 200,000 years) has demonstrated the long time stability of ferric gels, although an increase of medium range order around Fe is seen. (author)

This experiment uses a Tevatron-based neutrino beam to obtain a sample of Deep Inelastic Scattering (DIS) events which is over two orders of magnitude larger than past samples. We outline an innovative method for fitting the structure functions using a parameterized energy shift which yields reduced systematic uncertainties. High statistics measurements, in combination with improved systematics, will enable NuSOnG to perform discerning tests of fundamental Standard Model parameters as we search for deviations which may hint of 'Beyond the Standard Model' physics.

    Kawashima, Daisuke; Kawano, Kenji

    2017-09-01

    Although Japan has a high suicide rate, there is insufficient research on the experiences of suicide-bereaved individuals. We investigated the qualitative aspects of the meaning reconstruction process after a loss to suicide. We conducted a life-story interview using open-ended questions with one middle-aged Japanese woman who lost her son to suicide. We used a narrative approach to transcribe and code the participant's narratives for analysis. The analysis revealed three meaning groups that structured the participant's reactions to the suicide: making sense of her son's death and life, relationships with other people, and reconstruction of a bond with the deceased. The belief that death is not an eternal split and that there is a connection between the living and the deceased reduced the pain felt by our participant. Furthermore, the narratives worked as scaffolds in the meaning reconstruction process. We discuss our results in the light of cross-cultural differences in the grieving process.

  2. An X-linked sex ratio distorter in Drosophila simulans that kills or incapacitates both noncarrier sperm and sons.

    Science.gov (United States)

    Rice, William R

    2014-07-31

    Genomic conflict occurs when a genomic component gains a reproductive advantage at the expense of the organism as a whole. X-linked segregation distorters kill or incapacitate Y-bearing sperm, thereby gaining a transmission advantage but also reducing male fertility and generating a female-biased sex ratio. When some damaged, Y-bearing sperm survive and fertilize eggs, then the segregation distortion phenotype could be expanded by harming or killing sons in the next generation. X-linked son-killers are predicted by theory to be favored by natural selection and evolve when brothers and sisters compete for shared limiting resources and/or when brothers reduce the inclusive fitness of their sisters via sib-mating-a phenomenon called SA-zygotic drive. Here I develop and use a process-of-elimination screen to show that an unclassified X-linked sex ratio distorter (skew) in Drosophila simulans kills or incapacitates noncarrier sperm and also kills a substantial proportion of sons, i.e., it has both a segregation distortion and a SA-zygotic drive phenotype. There are three unique X-linked segregation distorters known to occur in D. simulans named Winters, Durham, and Paris. Autosomal-dominant suppressors of Winters (Nmy) and Durham (Tmy) failed to suppress skew. A Y-linked suppressor of Paris, however, did suppress skew, and a recombination test failed to detect recombinants between these two sex ratio distorters, indicating that they are tightly linked and plausibly identical or allelic. Son-killing may be an important yet unrecognized component of other X-linked segregation distorters. Copyright © 2014 Rice.

Levy is an interesting example of a Baltimore-based, family-owned niche business that existedfor 90 years, through three generations ofa singlefamily. The M.S. Levy and Sons story has two main chapters. The first covers the period from its founding by Michael Simon Levy in the 1870s through his son Julius’ death in 1926. This is the story of ascension. A premonition about the coming popularity of straw hats, together with a small but important technological breakthrough, positioned a family and a small industry for significant expansion. The second period began in 1930 with the introduction of wool felt hats and the death of William, M.S. Levy’s oldest son, and includes the Great Depression, unionization, merger, third generation leadership, and finally, in 1959, the family’s withdrawal from the industry. This later period, as told by grandsons of the founder, is the story of struggle followed by decline.

    Full Text Available We investigated how mothers’ parenting behaviors and personal characteristics were related to risk-taking by young children. We tested contrasting predictions from evolutionary and social role theories with the former predicting higher risk-taking by boys compared to girls and the latter predicting that mothers would influence children’s gender role development with risk-taking occurring more in children parented with higher levels of harshness (i.e., authoritarian parenting style. In our study, mothers reported their own gender roles and parenting styles as well as their children’s risk-taking and activities related to gender roles. The results were only partially consistent with the two theories, as the amount of risk-taking by sons and daughters did not differ significantly and risk-taking by daughters, but not sons, was positively related to mothers’ use of the authoritarian parenting style and the girls’ engagement in masculine activities. Risk-taking by sons was not predicted by any combination of mother-related variables. Overall, mothers who were higher in femininity used more authoritative and less authoritarian parenting styles. Theoretical implications as well as implications for predicting and reducing children’s risk-taking are discussed.

    This study examined the effects of the Son-Rise Program (SRP), an intensive treatment aimed to improve child-initiated social communication in children with autism. Six children between the ages of 47 and 78 months were provided with 40 h of SRP, with pre- to post-treatment behavioral changes tested using a novel passive interaction probe task. Results showed an increase in the frequency of spontaneous social orienting and gestural communication for the experimental children, compared to six age- and behaviorally-matched control children with autism. In addition, for the children who received treatment, the duration of social dyadic interactions and total time spent engaged in social interaction increased from pre- to post-treatment. These findings suggest that intensive intervention focused on fostering child-initiated interaction increases social-communicative behaviors in children with autism. Readers will be able to describe the principles underlying the Son-Rise Program, a developmental approach to treatment for autism. Readers will be able to explain the methods of the investigation of a 5-day intensive Son-Rise Program and the results that report change in social communication in children with autism.

    Long-term storage of high-level nuclear waste glass in France is expected to occur in an engineered barrier system (EBS) located in a subsurface Callovo-Oxfordian (COx) clay rock formation in the Paris Basin in northeastern France. Understanding the behavior of glass dissolution in the complex system is critical to be able to reliably model the performance of the glass in this complex environment. To simulate this multi-barrier repository scenario in the laboratory, several tests have been performed to measure glass dissolution rates of the simulated high-level nuclear waste glass, SON68, in the presence of COx claystone at 90 °C. Experiments utilized a High-Performance Liquid Chromatography (HPLC) pump to pass simulated Bure site COx pore water through a reaction cell containing SON68 placed between two COx claystone cores for durations up to 200 days. Silicon concentrations at the outlet were similar in all experiments, even the blank experiment with only the COx claystone (∼4 mg/L at 25 °C and ∼15 mg/L at 90 °C). The steady-state pH of the effluent, measured at room temperature, was roughly 7.1 for the blank and 7.3-7.6 for the glass-containing experiments demonstrating the pH buffering capacity of the COx claystone. Dissolution rates for SON68 in the presence of the claystone were elevated compared to those obtained from flow-through experiments conducted with SON68 without claystone in silica-saturated solutions at the same temperature and similar pH values. Additionally, through surface examination of the monoliths, the side of the monolith in direct contact with the claystone was seen to have a corrosion thickness 2.5× greater than the side in contact with the bulk glass powder. Results from one experiment containing 32Si-doped SON68 also suggest that the movement of Si through the claystone is controlled by a chemically coupled transport with a Si retention factor, Kd, of 900 mL/g.

    In the United States, nearly half of high school students are sexually active, and adolescents experience high rates of unintended pregnancy and sexually transmitted diseases. Parents can have an important influence on their children's sexual behaviour, but many parents do not talk with their children about sexual topics. Research has shown significant differences in parent-child communication about sexual topics depending on the gender of both the parent and the child. Little is known, however, about the reasons for these gender differences. The purpose of this paper is to describe how factors associated with parent-child communication about sexual topics differ by gender. Data are from a nationwide online survey with 829 fathers and 1,113 mothers of children aged 10 to 14. For each of the four gender groups (fathers of sons, fathers of daughters, mothers of sons, mothers of daughters), we calculated the distribution of responses to questions assessing (1) parent-child communication about sex-related topics, and (2) factors associated with that communication. We used chi-square tests to determine whether the distributions differed and the false discovery rate control to reduce the likelihood of type I errors. With both sons and daughters, fathers communicated less about sexual topics than mothers did. Fathers also had lower levels of many characteristics that facilitate communication about sex (e.g., lower self-efficacy and lower expectations that talking to their children about sex would have positive outcomes). Compared with parents of sons, parents of daughters (both mothers and fathers) talked more about sexual topics, were more concerned about potential harmful consequences of sexual activity, and were more disapproving of their child having sex at an early age. Using a large national sample, this study confirms findings from previous studies showing gender differences in parent-child communication about sexual topics and identifies gender differences in

In the development of science; the cumulative progress and effective sharing of information comes to the forefront. Within the scope of science, producing new information requires a social approach. Because science has more participants every day so the meaning and importance of science also becomes different. In this sense, the idea of open science, which is based on open access, open data and open source, continues to mediate the socialization of information as well as the purpose of the rapid spread of scientific research results among scientists.

    Full Text Available This paper explores the diversity and complexity of Rubens’s humanist interests and illustrates his appropriation of learned and esoteric knowledge, by discussing the anonymous painting in the Hermitage Museum in St. Petersburg in which Rubens is portrayed together with his son Albert. This portrait also depicts a sculpture from Rubens’s collection, that of Hecate Triformis, who in antiquity was considered to be a goddess of the underworld. By focusing on the books, manuscripts, Gnostic gems, and the Hecate statue from the artist’s collections, this paper will provide a new iconographic analysis of the Hermitage painting.

    Full Text Available Background During childhood, parents are the first and most important individuals who form the base of the content of gender stereotypes in children. A parent’s expectations about the extent a child’s behaviour should be line with gender stereotypes also depends on the intensity of a parent’s sexism. A parent’s sexism may be exhibited in parental attitudes. Hence, in our study we analysed the relationship between parental ambivalent sexism and parental attitudes within dyads of mothers and fathers with a special focus on the role of the gender of both parents and children. Participants and procedure Two hundred and ninety-four couples of parents of five-year-olds (153 girls, 141 boys participated. The Ambivalent Sexism Inventory (ASI was used to measure levels of sexism, and the Parental Attitudes Scale (SPR was used to assess parental attitudes. Results In terms of the profile of parental attitudes, regardless of the child’s sex, mothers and fathers scored highest for inconsequent and demanding attitudes, and lowest for overprotective and autonomy attitudes. The child’s sex is also not important for the overall levels of parents’ sexism – fathers exhibit higher levels of hostile sexism in comparison to mothers. Only the mothers’ education level is important for levels of sexism – women with higher education exhibited the lowest levels of hostile sexism. The child’s sex moderates relationships between parents’ sexism and parental attitudes. In the case of mothers of sons, the intensity of benevolent sexism is negatively related to overprotective and demanding attitudes. The more educated the mothers of sons, the more demanding they were. For fathers of sons, the inconsequence attitude increases under the influence of both hostile and benevolent sexism. Among fathers of daughters, hostile sexism strengthens the overprotective attitude, while levels of both benevolent and hostile sexism as well as education influence the

    We introduce a simple model of SO(N) spins with two-site interactions which is amenable to quantum Monte Carlo studies without a sign problem on nonbipartite lattices. We present numerical results for this model on the two-dimensional triangular lattice where we find evidence for a spin nematic at small N, a valence-bond solid at large N, and a quantum spin liquid at intermediate N. By the introduction of a sign-free four-site interaction, we uncover a rich phase diagram with evidence for both first-order and exotic continuous phase transitions.

    The nuclear pore complex proteins SonA and SonB, the orthologs of mammalian RAE1 and NUP98, respectively, were identified in Aspergillus nidulans as cold-sensitive suppressors of a temperature-sensitive allele of the essential mitotic NIMA kinase (nimA1). Subsequent analyses found that sonB1 mutants exhibit temperature-dependent DNA damage sensitivity. To understand this pathway further, we performed a genetic screen to isolate additional conditional DNA damage-sensitive suppressors of nimA1. We identified two new alleles of SonA and four intragenic nimA mutations that suppress the temperature sensitivity of the nimA1 mutant. In addition, we identified SonC, a previously unstudied binuclear zinc cluster protein involved with NIMA and the DNA damage response. Like sonA and sonB, sonC is an essential gene. SonC localizes to nuclei and partially disperses during mitosis. When the nucleolar organizer region (NOR) undergoes mitotic condensation and removal from the nucleolus, nuclear SonC and histone H1 localize in a mutually exclusive manner with H1 being removed from the NOR region and SonC being absent from the end of the chromosome beyond the NOR. This region of chromatin is adjacent to a cluster of nuclear pore complexes to which NIMA localizes last during its progression around the nuclear envelope during initiation of mitosis. The results genetically extend the NIMA regulatory system to include a protein with selective large-scale chromatin location observed during mitosis. The data suggest a model in which NIMA and SonC, its new chromatin-associated suppressor, might help to orchestrate global chromatin states during mitosis and the DNA damage response.

    Routine administration of the quadrivalent human papillomavirus (HPV) vaccine has been recommended for 11-12-year-old males since 2011, but coverage remains low. In a U.S. national sample of parents of 11-17-year-old males (n=779), 78.6% of parents reported their sons had not received the HPV vaccine. The most common reason for non-vaccination (56.7%) was "My doctor or healthcare provider has not recommended it." Parents citing only logistical reasons for non-vaccination (e.g., lack of recommendation, access, or education, n=384) reported significantly higher vaccine acceptability than parents reporting a combination of attitudinal (e.g., concerns about vaccine safety or efficacy) and logistical barriers (n=92), while parents citing only attitudinal barriers (n=73) reported the lowest level of vaccine acceptability. In sum, many parents are willing but have not vaccinated sons due to logistical barriers, most commonly lack of healthcare provider recommendation. These findings have important implications for increasing HPV vaccination coverage among adolescent males. Copyright © 2014 Elsevier Ltd. All rights reserved.

    2008-09-01

    Sexual imprinting on discrete variation that serves the identification of species, morphs or sexes is well documented. By contrast, sexual imprinting on continuous variation leading to individual differences in mating preferences within a single species, morph and sex has been studied only once (in humans). We measured female preferences in a captive population of wild-type zebra finches. Individual cross-fostering ensured that all subjects grew up with unrelated foster parents and nest mates. Females from two cohorts (N = 113) were given a simultaneous choice between (two or four) unfamiliar males, one of which was a genetic son of their foster parents (SFP). We found no significant overall preference for the SFP (combined effect size d = 0.14 +/- 0.15). Additionally, we tested if foster parent traits could potentially explain between-female variation in preferences. However, neither the effectiveness of cooperation between the parents nor male contribution to parental care affected female preferences for the son of the foster father. We conclude that at least in zebra finches sexual imprinting is not a major source of between-individual variation in mating preferences.

    We describe a new species of Cyrtodactylus on the basis of four specimens collected from the limestone karst forest of Phu Yen District, Son La Province, Vietnam. Cyrtodactylus sonlaensis sp. nov. is distinguished from the remaining Indochinese bent-toed geckos by a combination of the following characters: maximum SVL of 83.2 mm; dorsal tubercles in 13-15 irregular rows; ventral scales in 34-42 rows; ventrolateral folds prominent without interspersed tubercles; enlarged femoral scales 15-17 on each thigh; femoral pores 14-15 on each thigh in males, absent in females; precloacal pores 8, in a continuous row in males, absent in females; postcloacal tubercles 2 or 3; lamellae under toe IV 18-21; dorsal head with dark brown markings, in oval and arched shapes; nuchal loop discontinuous; dorsum with five brown bands between limb insertions, third and fourth bands discontinuous; subcaudal scales distinctly enlarged. In phylogenetic analyses, the new species is nested in a clade consisting of C. huongsonensis and C. soni from northern Vietnam and C. cf. pulchellus from Malaysia based on maximum likelihood and Bayesian analyses. In addition, we record Cyrtodactylus otai Nguyen, Le, Pham, Ngo, Hoang, Pham & Ziegler for the first time from Son La Province based on specimens collected from Van Ho District.

    Single deletions of mitochondrial DNA (mtDNA) are associated with three major clinical conditions: Kearns-Sayre syndrome, a multisystem disorder; Pearson syndrome (PS), a disorder of the hematopoietic system; and progressive external ophthalmoplegia (PEO), primarily affecting the ocular muscles. Typically, single mtDNA deletions are sporadic events, since the mothers, siblings, and offspring of affected individuals are unaffected. We studied a woman who presented with PEO, ptosis, and weakness of pharyngeal, facial, neck, and limb muscles. She had two unaffected children, but another of her children, an infant son, had sideroblastic anemia, was diagnosed with PS, and died at age 1 year. Morphological analysis of a muscle biopsy sample from the mother showed cytochrome c oxidase-negative ragged-red fibers-a typical pattern in patients with mtDNA deletions. Southern blot analysis using multiple restriction endonucleases and probed with multiple mtDNA fragments showed that both the mother and her infant son harbored an identical 5,355-bp single deletion in mtDNA, without flanking direct repeats. The deletion was the only abnormal species of mtDNA identified in both patients, and there was no evidence for duplications. We conclude that, although the vast majority of single large-scale deletions in mtDNA are sporadic, in rare cases, single deletions can be transmitted through the germline.

A partir de esta perspectiva, se estudió quiénes son pobres en Colombia y qué características de los hogares determinan dicha condición para el 2003. A partir de la Encuesta de Calidad de Vida, se realizó un análisis logit para identifi car y medir la incidencia de algunos factores en la probabilidad de que un hogar sea clasifi cado como pobre. Estas estimaciones mostraron que los hogares que tienen más probabilidad de considerarse como pobres son aquellos en los que los jefes de hogar eran analfabetas, mujeres, los que se ocuparon en labores agrícolas o que hacían parte de alguna etnia. Adicionalmente, se encontró que los hogares que tenían menores de 12 años tuvieron más de probabilidad de ser pobres. Finalmente, los hogares cuyo jefe de hogar tenía mayor nivel educativo, tenían menor probabilidad de ser pobres, siendo mayor el efecto educativo de su cónyuge.

  18. When mothers make sons sexy: maternal effects contribute to the increased sexual attractiveness of extra-pair offspring.

    Science.gov (United States)

    Tschirren, Barbara; Postma, Erik; Rutstein, Alison N; Griffith, Simon C

    2012-03-22

    Quality differences between offspring sired by the social and by an extra-pair partner are usually assumed to have a genetic basis, reflecting genetic benefits of female extra-pair mate choice. In the zebra finch (Taeniopygia guttata), we identified a colour ornament that is under sexual selection and appears to have a heritable basis. Hence, by engaging in extra-pair copulations with highly ornamented males, females could, in theory, obtain genes for increased offspring attractiveness. Indeed, sons sired by extra-pair partners had larger ornaments, seemingly supporting the genetic benefit hypothesis. Yet, when comparing ornament size of the social and extra-pair partners, there was no difference. Hence, the observed differences most likely had an environmental basis, mediated, for example, via differential maternal investment of resources into the eggs fertilized by extra-pair and social partners. Such maternal effects may (at least partly) be mediated by egg size, which we found to be associated with mean ornament expression in sons. Our results are consistent with the idea that maternal effects can shape sexual selection by altering the genotype-phenotype relationship for ornamentation. They also caution against automatically attributing greater offspring attractiveness or viability to an extra-pair mate's superior genetic quality, as without controlling for differential maternal investment we may significantly overestimate the role of genetic benefits in the evolution of extra-pair mating behaviour.

  19. Science Fairs for Science Literacy

    2014-12-01

    Science literacy is imperative for well informed civic and personal decision making, yet only a quarter of American adults are proficient enough in science to understand science stories reported in the popular press. Hands-on research increases confidence in and understanding of science. When guiding students in designing and conducting science fair projects, mentors can foster science literacy by helping students focus on three goals: (1) articulating hypotheses or questions, (2) designing feasible projects, and (3) learning to make and interpret graphs. These objectives introduce students to the methodological nature of scientific research and give them the tools to interpret scientific facts and data in order to make informed decisions for themselves and society.

    A recent poll showed that most people think of science as technology and engineering—life-saving drugs, computers, space exploration, and so on. This was, in fact, the promise of the founders of modern science in the 17th century. It is less commonly understood that social and behavioral sciences have also produced technologies and engineering that dominate our everyday lives. These include polling, marketing, management, insurance, and public health programs.

    The May 2012 Sackler Colloquium on "The Science of Science Communication" brought together scientists with research to communicate and scientists whose research could facilitate that communication. The latter include decision scientists who can identify the scientific results that an audience needs to know, from among all of the scientific results that it would be nice to know; behavioral scientists who can design ways to convey those results and then evaluate the success of those attempts; and social scientists who can create the channels needed for trustworthy communications. This overview offers an introduction to these communication sciences and their roles in science-based communication programs.

  10. Science teaching in science education

    2016-06-01

    Reading the interesting article Discerning selective traditions in science education by Per Sund , which is published in this issue of CSSE, allows us to open the discussion on procedures for teaching science today. Clearly there is overlap between the teaching of science and other areas of knowledge. However, we must constantly develop new methods to teach and differentiate between science education and teaching science in response to the changing needs of our students, and we must analyze what role teachers and teacher educators play in both. We must continually examine the methods and concepts involved in developing pedagogical content knowledge in science teachers. Otherwise, the possibility that these routines, based on subjective traditions, prevent emerging processes of educational innovation. Modern science is an enormous field of knowledge in its own right, which is made more expansive when examined within the context of its place in society. We propose the need to design educative interactions around situations that involve science and society. Science education must provide students with all four dimensions of the cognitive process: factual knowledge, conceptual knowledge, procedural knowledge, and metacognitive knowledge. We can observe in classrooms at all levels of education that students understand the concepts better when they have the opportunity to apply the scientific knowledge in a personally relevant way. When students find value in practical exercises and they are provided opportunities to reinterpret their experiences, greater learning gains are achieved. In this sense, a key aspect of educational innovation is the change in teaching methodology. We need new tools to respond to new problems. A shift in teacher education is needed to realize the rewards of situating science questions in a societal context and opening classroom doors to active methodologies in science education to promote meaningful learning through meaningful teaching.

    2016-03-01

    On rare occasions in the history of science, remarkable discoveries transform human society and forever alter mankind's view of the world. Examples of such discoveries include the heliocentric theory, Newtonian physics, the germ theory of disease, quantum theory, plate tectonics and the discovery that DNA carries genetic information. The science philosopher Thomas Kuhn famously described science as long periods of normality punctuated by times of crisis, when anomalous observations culminate in revolutionary changes that replace one paradigm with another. This essay examines several transformative discoveries in the light of Kuhn's formulation. We find that each scientific revolution is unique, with disparate origins that may include puzzle solving, serendipity, inspiration, or a convergence of disparate observations. The causes of revolutionary science are varied and lack an obvious common structure. Moreover, it can be difficult to draw a clear distinction between so-called normal and revolutionary science. Revolutionary discoveries often emerge from basic science and are critically dependent on nonrevolutionary research. Revolutionary discoveries may be conceptual or technological in nature, lead to the creation of new fields, and have a lasting impact on many fields in addition to the field from which they emerge. In contrast to political revolutions, scientific revolutions do not necessarily require the destruction of the previous order. For humanity to continue to benefit from revolutionary discoveries, a broad palette of scientific inquiry with a particular emphasis on basic science should be supported.

    Koerner, Susan Silverberg; Wallace, Sara; Lehman, Stephanie Jacobs; Lee, Sun-A; Escalante, Kristine A

    2004-03-01

    This study addressed two main questions: (a) Are adolescent sons and daughters exposed to sensitive maternal disclosures after divorce with similar frequency and in similar detail? and (b) Does gender act as a moderator in the association between maternal disclosures and adolescent adjustment difficulties? Forced-choice and open-ended data were collected from 194 adolescents within 2 years after their parents' divorce. Quantitative analyses revealed that although the majority of adolescents experience some level of maternal disclosure, neither frequency nor detail of maternal disclosure differed as a function of adolescent gender. Frequent and detailed maternal disclosures were associated with adolescent adjustment difficulties, primarily psychological distress. Gender did not moderate that significant association. Qualitative analysis shed light on the link between maternal disclosures and adolescent distress, suggested the importance of how disclosures are made, and revealed several gender differences in reactions to maternal disclosures. Implications of the findings are discussed.

  19. Deletion of locus D15S113 in a mother and son without features of Angelman syndrome

    Deletions of the proximal long arm of chromosome 15 result in Angelman syndrome when inherited from the mother and Prader-Willi syndrome when inherited from the father. The minimal critical deletion region for Angelman syndrome has been reported to include D15S74 (B1.5), D15S10 (TD3-21), and D15S113 (LS6-1). We report a mother and son who have deletions that include D15S113 but who do not have features of Angelman syndrome. D.H. is a 10-year-old white male referred for genetic evaluation due to mental retardation. He has mild to moderate mental retardation and minor dysmorphic features, including downslanting palpebral fissures, prominent nose, broad forehead, small chin, midface hypoplasia, and large ears. His mother (B.S.) has slightly downslanting palpebral fissures and a borderline intellectual deficit. Neither individual has the seizures, excessive laughter, hand clapping, ataxia or facial dysmorphism which are characteristic of Angelman syndrome. The linear order of probes mapping to 15q11-q13 is 15cen-D15S11-D15S13-D15S10-D15S113-GABRB3-D15S12-tel. The proximal border of the deletion in our patients lies between D15S10 and D15S113. The fact that these two individuals do not have Angelman syndrome, despite deletion of D15S113, suggests that the Angelman syndrome critical deletion region should be further refined to exclude the D15S113 locus. In addition, the findings of a more severe intellectual impairment in the son than in the mother suggests that the region immediately telomeric to the critical deletion region for Angelman syndrome may contain imprintable genes that influence intellectual function.

  10. ‘Unkind and cruel, to deceive your Son | In borrow’d Shapes, and his Embrace to shun’: Mother-son love in T. S. Eliot’s ‘La Figlia Che Piange’

    Directory of Open Access Journals (Sweden)

    Matthew Geary

    2015-01-01

    Full Text Available T. S. Eliot's "La Figlia Che Piange" (1916 is a curious anomaly in his early works. It stands out as a love poem of outstanding grace portraying a more positive relationship to the feminine compared to other poems contemporaneous with its writing such as "The Love Song of St. Sebastian" (1914 and "Hysteria" (1915. This essay shows the import of Eliot's chosen epigraph for "La Figlia" taken from Virgil's Aeneid to have been largely neglected or misread by critics. As a consequence, it argues that critical readings have crucially missed the presence of a shrouded maternal aspect within the poem. Through the lens of Lacanian psychoanalysis and the work of adherents to Lacanian theory — such as Bruce Fink, Shoshana Felman and Slavoj Zizek — this paper newly argues that the poem's meditation on the issues of union and separation between two lovers is in fact a screen for deeper unconscious ambivalent feelings between mother and son. That is to say, Eliot's "La Figlia Che Piange" shows a failed attempt to reconstruct, traverse and separate from the "fundamental fantasy" unconsciously orientating the male speaker of the poem and his desire.

    2001-09-01

    The debate between mentalism/cognitivism and behaviorism is analyzed, and it is concluded that behaviorism is the philosophy more closely associated with psychology as a behavioral science, the cognitive approach being more closely aligned with biological science. Specific objections to mentalistic interpretations of behavioral phenomena are detailed, and examples from clinical psychology are used to show the importance of behavioral approaches in applied domains. It is argued that the relation between behavior theory and clinical psychology is critical to the continued advancement of applied psychology. Behavior analysis is offered as a direct, applied extension of behavior theory as well as a highly practical and effective approach for understanding, explaining, and modifying the factors that contribute to and maintain maladaptive behaviors.

  13. Regional vegetation patterns at lake Son Kul reveal Holocene climatic variability in central Tien Shan (Kyrgyzstan, Central Asia)

    Mathis, Marie; Sorrel, Philippe; Klotz, Stefan; Huang, Xiangtong; Oberhänsli, Hedi

    2014-04-01

    A multiproxy study was conducted on Holocene sediments from the alpine lake Son Kul (3010 m a.s.l, 41°48‧33N/75°07‧38E) in central Tien Shan (Kyrgyzstan). The combination of high-resolution pollen, palynofacies and magnetic susceptibility data allowed reconstruction of changes in sedimentary and vegetation dynamics regionally at Son Kul between 8350 and ca 2000 cal. BP. Using pollen data to quantify climatic parameters, a quantitative reconstruction of climatic conditions was performed using the "Modern Analogue Vegetation types" (MAV) method and a ranged index of seasonality. The most temperate (e.g. moister) climate conditions occurred between 8350 and 5000-4500 cal. BP when alpine meadow vegetation was enriched in plants requiring moister conditions and trees developed regionally. Conversely, more continental and arid conditions prevailed after 4500 cal. BP with the decline of arboreal vegetation (especially Juniperus) and the extension of an alpine steppe-meadow along with a regional decrease in Poaceae. This climate transition was associated with a change in seasonality as the continentality greatly intensified after 5000-4500 cal. BP. Our results are consistent with other records from the Tien Shan range and the Chinese Province Xinjiang showing that relatively wet conditions prevailed regionally before 5000 cal.

From a more global perspective, we highlight that regional rainfall in central Tien Shan and western Central Asia is likely to be predominantly controlled by the Eastern Mediterranean cyclonic system and North Atlantic climate, as based on the close correspondence between climatic archives from western Central Asia, the Levant, the Eastern Mediterranean and Caspian Sea regions. However, the effect of monsoonal dynamics on the regional climatic system in central Tien Shan still remains dubious, since recent modelling studies have shown that no dynamic link exists between

  16. The (dis)unity of nursing science.

    Science.gov (United States)

    Bluhm, Robyn L

    2014-10-01

    This paper looks at the implications of contemporary work in philosophy of science for nursing science. Early work on the nature of theories in nursing was strongly influenced by logical empiricism, and this influence remains even long after nurse scholars have come to reject logical empiricism as an adequate philosophy of science. Combined with the need to establish nursing as an autonomous profession, nursing theory's use of logical empiricism has led to serious conceptual problems. Philosophers of science have also rejected many of the central tenets of logical empiricism, including its focus on the logical justification of theories and the idea that science is, or should be, unified. Instead, there has been an increasing focus on the practice of science, which in turn has led to a pluralist understanding of science that emphasizes the construction of scientific models that are appropriate for certain purposes or in certain contexts. I suggest that this approach to philosophy of science may provide better resources for nursing science. © 2014 John Wiley & Sons Ltd.

  17. Pure Science and Applied Science

    Robert J. Aumann

    2011-01-01

    Full Text Available (Excerpt The name of my talk is Pure Science and Applied Science, and the idea I would like to sell to you today is that there is no such thing as “pure” or “applied” science. In other words, there is such a thing as science, but there is no difference between pure and applied science. Science is one entity and cannot be separated into different categories. In order to back that up, I would like to tell you a little story. As an undergraduate, I studied mathematics at City College in New York. At that time, what was called Pure Mathematics was in vogue, and the more prominent mathematicians were a little contemptuous of any kind of application. A very famous, prominent mathematician in the first half of the previous century by the name of G. H. Hardy, who was in a branch of mathematics called number theory, said that the only thing he regretted was that he unwittingly did some important work in mathematical genetics that eventually turned out to have some application. … Such was the atmosphere in the late ’40s of the previous century and, being a young man and impressionable, I was swept up in this atmosphere.

  18. Exploring science through science fiction

    How does Einstein’s description of space and time compare with Dr. Who? Can James Bond really escape from an armor-plated railroad car by cutting through the floor with a laser concealed in a wristwatch? What would it take to create a fully-intelligent android, such as Star Trek’s Commander Data? How might we discover intelligent civilizations on other planets in the galaxy? Is human teleportation possible? Will our technological society ever reach the point at which it becomes lawful to discriminate on the basis of genetic information, as in the movie GATTACA? Exploring Science Through Science Fiction addresses these and other interesting questions, using science fiction as a springboard for discussing fundamental science concepts and cutting-edge science research. The book is designed as a primary text for a college-level course which should appeal to students in the fine arts and humanities as well as to science and engineering students.

  19. Is normal science good science?

    Directory of Open Access Journals (Sweden)

    Adrianna Kępińska

    2015-09-01

    Full Text Available “Normal science” is a concept introduced by Thomas Kuhn in The Structure of Scientific Revolutions (1962. In Kuhn’s view, normal science means “puzzle solving”, solving problems within the paradigm—framework most successful in solving current major scientific problems—rather than producing major novelties. This paper examines Kuhnian and Popperian accounts of normal science and their criticisms to assess if normal science is good. The advantage of normal science according to Kuhn was “psychological”: subjective satisfaction from successful “puzzle solving”. Popper argues for an “intellectual” science, one that consistently refutes conjectures (hypotheses and offers new ideas rather than focus on personal advantages. His account is criticized as too impersonal and idealistic. Feyerabend’s perspective seems more balanced; he argues for a community that would introduce new ideas, defend old ones, and enable scientists to develop in line with their subjective preferences. The paper concludes that normal science has no one clear-cut set of criteria encompassing its meaning and enabling clear assessment.

  1. Cognitive ability correlates positively with son birth and predicts cross-cultural variation of the offspring sex ratio

    Dama, Madhukar Shivajirao

    2013-06-01

    Human populations show remarkable variation in the sex ratio at birth which is believed to be related to the parental condition. In the present study, the global variation of sex ratio at birth (SRB, proportion of male offspring born) was analyzed with respect to indirect measure of condition, the intelligence quotient (IQ). IQ correlates strongly with lifespan across nations, which makes it a good indicator of health of the large populations. Relation between three standard measures of average national IQ and SRB was studied using multiple linear regression models. Average national IQ was positively correlated with SRB ( r = 0.54 to 0.57, p IQ emerged as a powerful predictor of SRB after controlling for the effects of all the known covariates like fertility, maternal age, polygyny prevalence, wealth, son preference, latitude, low birth weight, and neonatal mortality in the regression models. These results suggest that the striking variation of offspring sex ratio across nations could be caused in part by the difference in general condition of populations.

    Despite research that suggests parental communication may help deter high-risk sexual behavior among adolescents, parents report a lack of confidence in their ability to answer sexually related questions. The purpose of this study was to test the effect of a multimedia intervention on outcome expectations and perceived self-efficacy for the sex educator role for parents of African American adolescent males. A pilot study using mixed methods was conducted. A nonprobability sample (N = 61) was obtained from a large urban community using a combination of convenience and snowball recruitment methods. Self-efficacy and outcome expectations were measured using self-reported questionnaires. A multimedia intervention for use at home and incorporating an audio CD and associated activities was implemented over a 3-week time period. Outcome expectations and self-efficacy both significantly improved after the intervention (p parents' outcome expectancy and self-efficacy for talking about sex with adolescent sons. © 2013 Wiley Periodicals, Inc.

  3. Household opportunity costs of protecting and developing forest lands in Son La and Hoa Binh Provinces, Vietnam

    Full Text Available Vietnam has pilot-tested a payment for forest environmental services (PFES program in an effort to restore and protect forest areas, some of which have been severely degraded by the excessive cutting of trees by small-scale farmers planting annual crops on steep, sloping lands. The pilot program implemented in southern Vietnam seems to be successful, yet the program in northern Vietnam has not produced the desired rates of planting and maintaining forest areas. The reasons for these mixed results include differences in socio-economic characteristics and also the production and marketing opportunities available to rural households in the project areas. To gain insight regarding program participation, we examine the household-level opportunity costs of planting and ­maintaining small plots of forest trees in northern Vietnam. We find that small-scale farmers in Hoa Binh Province, with limited financial resources, prefer the annual revenue stream provided by crops such as maize and cassava, rather than waiting for 7 years to obtain revenue from a forest planting. Farmers in Son La Province, with limited access to markets, prefer annual crops because they are not able to sell bamboo shoots and other forest products harvested from their small plots. In both provinces, the payments offered for planting and maintaining forest trees are smaller than the opportunity costs of planting and harvesting annual crops. Thus, most households likely would choose not to participate in the PFES program, at current payment rates, if given the opportunity to decline.

  4. Slit-Dependent Endocytic Trafficking of the Robo Receptor Is Required for Son of Sevenless Recruitment and Midline Axon Repulsion.

    Rebecca K Chance

    2015-09-01

    Full Text Available Understanding how axon guidance receptors are activated by their extracellular ligands to regulate growth cone motility is critical to learning how proper wiring is established during development. Roundabout (Robo is one such guidance receptor that mediates repulsion from its ligand Slit in both invertebrates and vertebrates. Here we show that endocytic trafficking of the Robo receptor in response to Slit-binding is necessary for its repulsive signaling output. Dose-dependent genetic interactions and in vitro Robo activation assays support a role for Clathrin-dependent endocytosis, and entry into both the early and late endosomes as positive regulators of Slit-Robo signaling. We identify two conserved motifs in Robo's cytoplasmic domain that are required for its Clathrin-dependent endocytosis and activation in vitro; gain of function and genetic rescue experiments provide strong evidence that these trafficking events are required for Robo repulsive guidance activity in vivo. Our data support a model in which Robo's ligand-dependent internalization from the cell surface to the late endosome is essential for receptor activation and proper repulsive guidance at the midline by allowing recruitment of the downstream effector Son of Sevenless in a spatially constrained endocytic trafficking compartment.

  5. "Now if you have only sons you are dead": migration, gender, and family economy in twentieth century northwestern Ghana.

    Abdul-Korah, Gariba B

    2011-01-01

    This article explores the interconnectedness between labor migration, gender, and the family economy in northwestern Ghana in the 20th century. It focuses specifically on the Dagaaba of the Nadowli and Jirapa administrative districts of what is now the Upper West Region (UWR). It examines how the relationships between men and women in terms of roles, status, access to productive resources and inheritance, changed in tandem with broader changes in society in the 20th century; changes that over time produced enhanced value and elevated status for women in the family. These changes in gender relations are reflected increasingly in the belief among elderly men that ‘now if you have only sons, you are dead’. By focusing on the lived experiences of ordinary women and men in the migration process, it argues that even though indigenous social structures privileged men over women in almost all spheres of life, Dagaaba women were nonetheless significantly active in shaping the history of their communities and that gender relations in Dagaaba communities were not static — they changed over time and generation. This article contributes to the ongoing discussion of the internal migration phenomenon in West Africa, which has so far attracted scant historical analysis.

  7. How parasitoid females produce sexy sons: a causal link between oviposition preference, dietary lipids and mate choice in Nasonia.

    Blaul, Birgit; Ruther, Joachim

    2011-11-07

    Sexual selection theory predicts that phenotypic traits used to choose a mate should reflect honestly the quality of the sender and thus, are often costly. Physiological costs arise if a signal depends on limited nutritional resources. Hence, the nutritional condition of an organism should determine both its quality as a potential mate and its ability to advertise this quality to the choosing sex. In insects, the quality of the offspring's nutrition is often determined by the ovipositing female. A causal connection, however, between the oviposition decisions of the mother and the mating chances of her offspring has never been shown. Here, we demonstrate that females of the parasitic wasp Nasonia vitripennis prefer those hosts for oviposition that have been experimentally enriched in linoleic acid (LA). We show by (13)C-labelling that LA from the host diet is a precursor of the male sex pheromone. Consequently, males from LA-rich hosts produce and release higher amounts of the pheromone and attract more virgin females than males from LA-poor hosts. Finally, males from LA-rich hosts possess three times as many spermatozoa as those from LA-poor hosts. Hence, females making the right oviposition decisions may increase both the fertility and the sexual attractiveness of their sons.

    2015-01-01

    Full Text Available El precio es una de las principales barreras de acceso a los medicamentos. Por ello es importante conocer cómo se forman los precios y qué factores determinan su cuantía y también qué formas de intervención y regulación son las más adecuadas teniendo en cuenta sus efectos, tanto sobre el acceso, como sobre la innovación, la producción local y otros posibles objetivos de la política de medicamentos. El análisis económico ha desarrollado un conjunto de modelos de mercado que permiten explicar el comportamiento de los precios, aunque los mercados reales divergen sustancialmente de los modelos teóricos. La regulación de precios está justificada por los llamados “fallos de mercado”; la regulación de precios basada en el costo de producción, la modalidad de control de precios más tradicional, ha caído en desuso a favor de los sistemas de precios de referencia internacionales y por la fijación del precio basada en el valor.

    Alexander I. Grishchenko

    2015-08-01

    Full Text Available This article demonstrates the apocryphal character of Jacob’s Blessing to His Sons (based on Gn 49, which is known according to the Palaea Interpretata. However, the Blessing was transferred to the Palaea together with the Testaments of the Twelve Patriarchs as their textual convoy, therefore the Blessing escorts the Testaments of the full redaction in the two copies known: in the so-called Archival Chronograph from the end of the 15th century (RGADA, f. 181, No. 279 and in No. 730 from the collection of the Trinity Lavra of St. Sergius (RGB, f. 304.I from the early 16th century, which contains the more correct version of both the Testaments and of the Blessing. The Slavonic-Russian Blessing is undoubtedly a translation from Greek, although the original Greek text has not yet been found; there is no such convoy in the Greek copies of the Testaments. One also cannot find any relation to the apocryphal Testament of Jacob known in Coptic, Ethiopic, and Arabic versions. Some connection can be detected between the Slavonic Blessing and the Commentary on Jacob’s Blessing by St. Hippolytus of Rome, which was preserved in the Greek version as well. The importance of textual study of the Slavonic Blessing is enhanced by the fact that this work—in the exegetical commentary on the blessing to Dan—contains the Slavonic Hebraism mashliakh ‘Judaic Messiah (in the Christian sense: Antichrist’ borrowed directly from Hebrew, with no Greek mediation, and hence this fact can indicate direct Judeo-Slavic contacts in the medieval Slavia Orthodoxa.

Algunos errores congénitos del metabolismo (ECM han sido asociados al SMSL y/o a episodios aparentemente letales EAL, aunque la mayoría de ellos suelen tener alguna expresión clínica que los hace potencialmente diagnosticables antes de la muerte, lo que permite ser descartados de entre las causas del SMSL. De ellos, los más estrechamente relacionados con el SMSL son los trastornos de la betaoxidación mitocondrial de ácidos grasos. Solo del 3 al 5 % de los SMSL pueden guardar relación con ECM. El mayor impacto que representa el conocimiento de la asociación de SMSL y estos trastornos, es precisamente la posibilidad de su prevención. El personal médico debe conocer que la más eficiente forma de prevenir el SMSL relacionado con los ECM, es la búsqueda activa de lactantes de riesgo al realizar una exhaustiva anamnesis. Estos casos deben ser objeto de estudios metabólicos especializados, para lo cual es imprescindible conocer los requisitos de obtención, conservación y traslado de muestras al Laboratorio de Referencia.

    Transthyretin-associated Familial Amyloid Polyneuropathy (TTR-FAP) is an autosomal dominant disease caused by the deposition of abnormal transthyretin that results from a gene mutation. Although rare worldwide, there are descriptions of several endemic foci, such as in Majorca, Balearic Islands, Spain. We aimed at describing a contemporary series of TTR-FAP patients in Son Llàtzer Hospital in Majorca from an epidemiological point of view in order to report their main clinical and laboratory characteristics. A retrospective, observational study was performed. Medical records from adult patients diagnosed with TTR-FAP from a single hospital were reviewed. Out of a total of 107 cases, 75 subjects were included: asymptomatic carriers (52.3%) and symptomatic patients (47.7%). Mean age was 58.3 years at the time of the study, and 50.7% were men. Mean age at diagnosis was 49.8 years. In addition, 42 patients (39.2%) had received a liver transplant, and time to liver transplantation was on average 29.56 months from the initial diagnosis. They all had the Val30Met mutation. The organs of the nervous system were those most frequently impaired (57.3%), and 83.9% of the symptomatic patients were fully ambulant (stage 1). Family history was reported in 69.3% of the cases, with the patient's father being the most commonly affected relative. Comorbidities were frequent, with high blood pressure being the most common. Our findings provide additional information on this condition and are useful for describing the demographic features, clinical presentation, diagnosis, and natural course of TTR-FAP in Majorca.

    Full Text Available Le Léviathan de Hobbes [1651] a subi de nombreuses attaques, au point qu’il est jugé responsable de la grande peste de 1665 et de l’incendie de Londres l’année suivante et que le parlement ouvre une procédure contre l’ouvrage. Aussi, lorsqu’en 1666, Thomas Hobbes veut publier la traduction latine de ce livre, il y adjoint trois appendices. La version latine de l’œuvre est généralement jugée plus acceptable que le texte originaire anglais. En étudiant la manière dont Hobbes traite de son matérialisme dans ces appendices, je tente de montrer que les addenda latins ne constituent en aucune manière un retour en arrière du texte, mais que le philosophe enrobe simplement davantage des propos que, par ailleurs, il rend plus radicaux.Hobbes’s Leviathan [1651] has been critiqued so much that it was held responsible for the Great Plague of 1665 and the Fire of London during the following year, resulting in the Parliament instituting proceedings against the book. Therefore, when in 1666 Thomas Hobbes wanted to publish a Latin translation of this book, he added three appendices. Generally, the Latin version of the work is considered more acceptable than the English original text. By studying how Hobbes deals with his materialism in these appendices, I try to show that the Latin additions are in no way a reversal of the text, but that the philosopher simply veiled more propositions, while at the same time making them more radical.

    Our science is critical to understanding the future prospects for life. The laboratory for natural sciences encompasses our planet and reaches into the solar system. The forces of nature respect no boundaries. But, we who try to understand these forces are handicapped by national, political, language, religious, and other concocted barriers. These barriers limit both our effectiveness as scientists and our ability to reach those outside our community who need to know what we have uncovered about our environment. An unencumbered worldwide scientific community has been an objective with limited successes for too long. Action began in earnest after the first world war with the formation of the various scientific Unions and ICSU. Fifty years later Keith Runcorn initiated another approach, when he proposed what quickly became EGS and which has grown and evolved with the merger with EUG. To be truly effective we need to communicate and share comfortably with colleagues worldwide. Personal relationships and trust are required. We count on a high level of ethical behavior within our community. We individually must also be constantly vigilant for the encroachment of the manmade barriers that have held back science through time immemorial. Our scientific organizations cannot achieve this alone. They will facilitate, however, the onus is on each of us to reach out and form interlocking informal communities, which will bring our whole planet-wide community together at many overlapping levels. When we achieve this community, our science will more bountiful and better address the needs of human society.

    1997-01-01

    What is good science? What goal--if any--is the proper end of scientific activity? Is there a legitimating authority that scientists mayclaim? Howserious athreat are the anti-science movements? These questions have long been debated but, as Gerald Holton points out, every era must offer its own responses. This book examines these questions not in the abstract but shows their historic roots and the answers emerging from the scientific and political controversies of this century. Employing the case-study method and the concept of scientific thematathat he has pioneered, Holton displays the broad scope of his insight into the workings of science: from the influence of Ernst Mach on twentiethcentury physicists, biologists, psychologists, and other thinkers to the rhetorical strategies used in the work of Albert Einstein, Niels Bohr, and others; from the bickering between Thomas Jefferson and the U.S. Congress over the proper form of federal sponsorship of scientific research to philosophical debates since Oswald...

  1. Biodegradation of the french reference nuclear glass SON 68 by Acidithiobacillus thiooxidans : protective effect of the biofilm,U and REE retention

    Although underground nuclear waste repositories are not expected to be favourable places for microbial activity, one should not exclude localized action of extremophilic bacteria on some materials involved in the storage concept. Among endogenous or accidentally introduced acidophiles, some are susceptible to lead to a locally drastic decreased in pH with potential consequences on materials corrosion. Experiments were performed with Acidithiobacillus thiooxidans on 100-125 μm french reference nuclear glass SON68 grains in a mineral medium under static conditions during 60 days at 25°C. Growth medium was periodically renewed and analyzed by ICP-AES and ICP-MS spectrometry for both major, traces and ultra-traces elements. Biofilm formation was evidenced by confocal laser microscopy, staining DNA with ethidium bromide and exopolysaccharides with calcofluor white. Biofilm thickness around material grains exceeded 20 μm under the chosen experimental conditions. It can be noticed that while numerous studies on biofilm formation upon interaction between Acidithiobacillus ferrooxidans and materials can be found in the literature, evidence for biofilm formation is still scarce for the case of the acidophilic bacterium A. thiooxidans. Presence of biofilm is a key parameter for material alteration at the solid/solution interface in biotic systems. Indeed, various constitutive elements of materials trapped in the polyanionic polymer of biofilm may also influence the alteration process. In particular, biofilm may reduce the alteration rate of materials by forming a protective barrier at their surface (Aouad et al., 2008). In this study, glass alteration rates, determined using strontium, molybdenum and caesium as tracers, showed that the biofilm has a protective effect against glass alteration. U and REE are efficiently trapped in the biogenic compartment of the system (exopolysaccharides (EPS) + bacterial cells). Biofilm analysis are in progress to determine whether these

    Introduction Analyse du profil bactériologique des pieds diabétiques pris en charge à l'hôpital militaire de Rabat et son influence sur l'antibiothérapie de première intention. Méthodes Etude prospective non randomisée étalée sur 18 mois, ayant concerné 105 patients. Après recueil des données et en attente des résultats bactériologiques nos patients ont été divisés en deux groupes: un groupe a été mis sous Amoxicilline + Acide clavulanique + Gentamycine (59 patients) et un groupe sous Ertapénème±Gentamycine (46 patients). Résultats L’étude a regroupé 85 hommes et 20 femmes (sexe ratio = 4.26). L’âge moyen est de 64.4 ans. La gangrène a été observée chez 79% des malades; elle était humide-donc surinfectée en principe- dans 43% des cas. Par ailleurs, 67% des malades ont un chiffre de globules blancs 12000 définissant une infection sévère. L'ostéolyse a été mise en évidence chez 27% de nos patients. Parmi les différentes techniques de prélèvements: 81% ont été profonds dont 21% de biopsie osseuse per opératoire et 14% de prélèvements combinés. 42% de ces prélèvements sont poly microbiens et 21% sont stériles. Les résultats bactériologiques viennent confirmer la prédominance des bactéries aérobies à Gram positif. Le taux de remplacement de l'Ertapénème est de 22% contre un taux de 50% pour l'Amoxiclav. Conclusion L'antibiothérapie ne doit être instaurée qu'en cas d'infection du pied diabétique diagnostiquée sur les critères cliniques établis par les consensus internationaux récents. Le respect des mesures de lutte contre la diffusion de la résistance bactérienne s'avère primordiale. PMID:27386024

    Full Text Available After some nobles and other fighting men surrendered Rochester castle to King John in 1215, John wanted to hang the nobles but refrained from doing so on the advice of one of his military captains. Would hanging the nobles for making war on the king have been lawful? This question about the law of treason has provoked inconclusive debate among historians who have sought to determine whether, in this period, making war against the English king was legally classified as lèse-majesté (crimen laesae majestatis, proditio or infidelitas. This article, however, asks whether the nobles whom John wanted to hang were guilty of traïson, as this vernacular term was used in the History of William Marshal (c. 1230. On this basis, the paper concludes that in all probability, the nobles who held Rochester against the king would not have been condemned as traitors, at least by their aristocratic peers.Cuando en 1215 ciertos nobles y otros combatientes se rindieron y entregaron el castillo de Rochester al rey Juan éste quiso colgarles, pero el consejo de uno de sus nobles le hizo absternerse. ¿Habría sido legítimo condenar a la horca a los que habían guerreado contra el rey? Cuestiones relativas al derecho de traición al intentar determinar si la guerra contra el rey de Inglaterra fue considerada en la época un crimen laesae majestatis, proditio, o infidelitas, según la definición que dan a estos términos las fuentes latinas, han suscitado debates interminables entre los historiadores. Este artículo, por el contrario, se pregunta si los nobles que el rey Juan deseaba colgar eran o no culpables de traición, en el sentido vernáculo del término que es usado en L’histoire de Guillaume le Maréchal (hacia 1230. Sobre esta base, la conclusión del artículo es que los nobles que ocuparon el castillo de Rochester, casi con total seguridad, no habrían sido condenados como traidores, al menos por sus pares.

    Full Text Available El síndrome de muerte súbita del lactante (SMSL no es un proceso aislado, sino un hecho multifactorial y multicausal, del cual cada día se restan alteraciones potencialmente diagnosticables, para pasar a ser un diagnóstico de exclusión. Algunos errores congénitos del metabolismo (ECM han sido asociados al SMSL y/o a episodios aparentemente letales EAL, aunque la mayoría de ellos suelen tener alguna expresión clínica que los hace potencialmente diagnosticables antes de la muerte, lo que permite ser descartados de entre las causas del SMSL. De ellos, los más estrechamente relacionados con el SMSL son los trastornos de la betaoxidación mitocondrial de ácidos grasos. Solo del 3 al 5 % de los SMSL pueden guardar relación con ECM. El mayor impacto que representa el conocimiento de la asociación de SMSL y estos trastornos, es precisamente la posibilidad de su prevención. El personal médico debe conocer que la más eficiente forma de prevenir el SMSL relacionado con los ECM, es la búsqueda activa de lactantes de riesgo al realizar una exhaustiva anamnesis. Estos casos deben ser objeto de estudios metabólicos especializados, para lo cual es imprescindible conocer los requisitos de obtención, conservación y traslado de muestras al Laboratorio de Referencia.The sudden infant death syndrome (SIDS is not an isolated process, but a multifactorial and multicausal event, of which there are less potentially diagnosable alterations every day, turning into an exclusion diagnosis. Some congenital errors of metabolism have been associated with SDSI and/or with apparently lethal episodes, although most of them may have some clinical expression that makes them potentially diagnosable before death, allowing to eliminate them from the causes of SIDS. Of them, the most closely related to SIDS are the disorders of mitochondrial betaoxidation of fatty acids. Only from 3 to 5 % of the SIDS may be related to CEM.

  8. Le problème du mal dans le Guide des Perplexes et son arrière-plan talmudique

    Directory of Open Access Journals (Sweden)

    Costa, José

    2010-12-01

    Full Text Available At first sight, the question of evil is regarded in the Guide for the Perplexed in a paradoxical manner. Thus, in Guide I, 2, Maimonides examines the notions of good and evil as subjective evaluations possessing neither the rigour not the exactness of the notions of true and false. However, the question of evil occupies an essential place in the Guide, as various modern authors have shown. This question is important to Maimonides because he is, in this respect, the heir of the rabbinic tradition and his conception of evil is largely based on an interaction with the Talmudic and Midrašic texts. Therefore, we would like to review thirty-nine rabbinic ‘quotes’ which appear in chapters 8 to 24 in the third part of the Guide and deal with the origin of evil, the meaning of suffering and the evil inclination. Maimonides reappropriates the midrašim that are susceptible of being in agreement with his rationalist positions and also quotes some rabbinic traditions that are too close to mu ͑tazilism, undoubtedly aware of the more profound resemblance that exists between the rabbinic and mu ͑tazilite doctrines of evil and retribution.A primera vista, el problema del mal es abordado en la Guía de Perplejos de manera paradójica. Para Maimónides, las nociones de bien y mal son subjetivas y no resultan ni rigorosas ni exactas, a la inversa de las nociones de verdad y falsedad (Guía I, 2. Sin embargo, el problema del mal es muy importante en la Guía, como lo demostraran varios autores. Maimónides es el heredero de la tradición rabínica y existe en la Guía una interacción entre la filosofia de Maimónides y los textos talmúdicos y midrásicos. Es particularmente el caso de las treinta y nueve citas rabínicas de la Guía II, 8-24, que tratan del origen del mal, del significado del sufrimiento y de la inclinación al mal. Maimónides cita los midrašim que concuerdan con sus posiciones racionalistas y evoca también algunas tradiciones rab

    Filmmaking is a science. It is observation, data collection, analysis, experimentation, structure, and presentation. Filmmaking is a process that is familiar to scientists. Observation - what we know is gained from observation of the world around us. Film allows us to focus this observation, to pick out details, to understand nuance, to direct seeing. Filmmaking is a tool for learning about the world. Data collection - to study what we observe we must see what it is now, and how it is changing. This element of filmmaking is collecting images, video, documenting events, and gathering information. Analysis - to understand the film data we have collected we must understand connections, correlations, and cause and effect. We ask questions. We discover. Experimentation - film allows us to experiment with different scenarios, to test observations and make models. Structure - what we find or what we want to present must be sorted into a structured format using the tools of writing, filming, and editing. Presentation - the final film is the result of what we observe, what observations we collect, what we learn from those observations, how we test what we've learned, and how we organize and show what we find. Online video is transforming the way we see the world. We now have easy access to lectures by the famous and the obscure; we can observe lab experiments, documentaries of field expeditions, and actually see recent research results. Video is omnipresent in our culture and supplements or even replaces writing in many applications. We can easily present our own scientific results to new and important audiences. Video can do a lot for science and scientists: It can provide an expanded audience for scientific news and information, educate thousands, spread the word about scientific developments, help frame controversial science issues, show real scientists at work in the real world, promote interest in scientific publications, and report on science-agency programs. It can

    Casadevall, Arturo; Fang, Ferric C

    2014-04-01

    As the body of scientific knowledge in a discipline increases, there is pressure for specialization. Fields spawn subfields that then become entities in themselves that promote further specialization. The process by which scientists join specialized groups has remarkable similarities to the guild system of the middle ages. The advantages of specialization of science include efficiency, the establishment of normative standards, and the potential for greater rigor in experimental research. However, specialization also carries risks of monopoly, monotony, and isolation. The current tendency to judge scientific work by the impact factor of the journal in which it is published may have roots in overspecialization, as scientists are less able to critically evaluate work outside their field than before. Scientists in particular define themselves through group identity and adopt practices that conform to the expectations and dynamics of such groups. As part of our continuing analysis of issues confronting contemporary science, we analyze the emergence and consequences of specialization in science, with a particular emphasis on microbiology, a field highly vulnerable to balkanization along microbial phylogenetic boundaries, and suggest that specialization carries significant costs. We propose measures to mitigate the detrimental effects of scientific specialism.

    The Materials Science Program is structured so that NASA s headquarters is responsible for the program content and selection, through the Enterprise Scientist, and MSFC provides for implementation of ground and flight programs with a Discipline Scientist and Discipline Manager. The Discipline Working Group of eminent scientists from outside of NASA acts in an advisory capacity and writes the Discipline Document from which the NRA content is derived. The program is reviewed approximately every three years by groups such as the Committee on Microgravity Research, the National Materials Advisory Board, and the OBPR Maximization and Prioritization (ReMaP) Task Force. The flight program has had as many as twenty-six principal investigators (PIs) in flight or flight definition stage, with the numbers of PIs in the future dependent on the results of the ReMaP Task Force and internal reviews. Each project has a NASA-appointed Project Scientist, considered a half-time job, who assists the PI in understanding and preparing for internal reviews such as the Science Concept Review and Requirements Definition Review. The Project Scientist also insures that the PI gets the maximum science support from MSFC, represents the PI to the MSFC community, and collaborates with the Project Manager to insure the project is well-supported and remains vital. Currently available flight equipment includes the Materials Science Research Rack (MSRR-1) and Microgravity Science Glovebox. Ground based projects fall into one or more of several categories. Intellectual Underpinning of Flight Program projects include theoretical studies backed by modeling and computer simulations; bring to maturity new research, often by young researchers, and may include preliminary short duration low gravity experiments in the KC-135 aircraft or drop tube; enable characterization of data sets from previous flights; and provide thermophysical property determinations to aid PIs.

El tiempo de estancia hospitalaria de los ancianos suele ser más prolongado que el del resto de pacientes. Objetivo: Analizar la capacidad de prestación de cuidados de 3 unidades de hospitalización de un hospital público y compararla con la demanda de cuidados de los ancianos. Métodos: Estudio prospectivo observacional en 3 unidades de hospitalización de medicina interna de un hospital universitario de la red pública de Andalucía (España. Se ha incluido una muestra de 190 pacientes ancianos hospitalizados. Las variables recogidas fueron: demográficas, relacionadas con la hospitalización, demanda de cuidados y capacidad de prestación de cuidados de la plantilla de enfermería. Los datos se han obtenido del sistema de información del hospital, del conjunto mínimo básico de datos de pacientes y por observación directa mediante el método de nivel de cuidados (MNC. Resultados: La edad media de los ancianos hospitalizados fue de 77,4 años, con 21,1% de mayores de 85 años. La estancia media fue de 15,68 días. La estimación de la capacidad de prestación de cuidados de la plantilla de enfermería fue de 2,8 horas/paciente/día (con un índice de enfermeras tituladas del 60%. A partir de la medición de niveles de dependencia, la demanda de cuidados media de los ancianos fue de 4,9 horas/paciente/día. Esta diferencia supone un déficit anual de 51 profesionales de enfermería en la plantilla de las 3 unidades de hospitalización. Los factores que influyen en la demanda de cuidados de los ancianos son la edad, días de estancia hospitalaria, el diagnóstico médico y el destino del paciente al alta. También se encuentra una relación con la presencia de un familiar acompañando al paciente (cuidador familiar. Los cuidados básicos representan un 65,7% del total de cuidados requeridos.

Going beyond issues unrelated to the theory itself, intra-theoretical interest characterizes the specific ways of approaching any science-related discipline, defining research topics and methodologies. This approach was developed by Jürgen Habermas in relation to empirical-analytical sciences, historical-hermeneutics sciences, and critical sciences; however, he did not make any specific references to health sciences. This article aims to contribute to shaping a general epistemological framework for health sciences, as well as its specific implications for the medical and nursing areas, via an analysis of the basic knowledge interests developed by Habermas. © 2015 John Wiley & Sons Ltd.

    Full Text Available The nanometer regime covers the transition from condensed matter behavior to atomic and molecular properties and thus is a very rich but also very demanding area in materials science. Close to the condensed matter side, properties and functions might still very well be scalable, whereas close to the atomic and molecular side, the scalability is mostly lost. Properties and functions change qualitatively or quantitatively by orders of magnitude when the dimensions become smaller than a critical size in the nanometer range. Examples are the ballistic regime for electron or spin transport at dimensions below the mean free path, near-field effects in scanning near-field optical microscopy and quantum wells when the dimensions are below an appropriate wavelength, novel electronic, mechanical, and chemical properties when the number of bulk atoms becomes smaller than that of surface atoms, quantum conduction, and Coulomb blockade. Thus, by going below a certain size, an abundance of novel properties and functions are at one's disposal, or, in other words, we can functionalize materials simply by reducing their size to the nanoscale.The key to the future lies in the functions that we give to materials, not just in finding 'novel functional materials'. This catch expression in many materials science programs and initiatives of the past two decades sounds great, but it is not what really counts. All materials are functional in one way or another and, therefore, all new materials are 'novel functional materials'. Certainly, finding new materials is always an important part of progress, but we should also focus on the much larger domain of novel functions that we can give to existing or modified materials. A good example is semiconductors: they are fifty or more years old and their properties are very well known, but they were not of widespread interest and use until the transistor changed their destiny into being the central material in the information

    Full Text Available Le seuil,abordé en tant que sujet représenté, est ici le moyen d’envisager la question  de la limite et de son dépassement dans le territoire de l’œuvre peinte, de l’installation et de la performance. La fresque de Masaccio, intitulée « Adam et Ève chassés du Paradis », réalisée vers 1425, constitue une étape décisive dans le traitement de l’espace de représentation. La suggestion d’une  profondeur, mais également, d’une épaisseur, apparaît, faisant basculer la peinture vers le naturalisme. Ainsi, au réalisme intellectuel du Moyen Age, se substitue un nouveau mode de figuration. L’artiste de la Renaissance quitte donc un territoire artistique pour explorer et poser les bases d’un art inédit. Dès lors, la toile, telle une zone de friction, se place et agit dans l’interstice séparant l’espace réel et l’espace représenté. La vision du spectateur, face au tableau, franchit ainsi le barrage de l’œuvre pour coloniser une fable topique amenée par l’illusion de la profondeur. La peinture est également le lieu où l’artiste révèle au spectateur, par le biais de stratagèmes plastiques, ses conditions de réalisation. A partir de là, une rupture s’opère entre la représentation et le fait de présenter. Art et vie s’interpénètrent alors, dans des installations ou des performances, offrant au spectateur un lieu milieu, dans lequel il est amené à s’affranchir de ces modèles. L’oeuvre est donc un seuil qu’il faut «traverser pour apprendre la solitude. » (Serres. Elle vibre d’instabilité et cristallise l’état singulier du changement. Enfin, elle conduit inéluctablement vers un devenir autre.The threshold as theme of representation is in this article used as a way to question the limit and its crossing in the territory of the painted work, of the installation and the performance.

Un tercio de ellas respondió, concluyéndose que la Revista de Biología Tropical, es la más influyente de la región según las personas consultadas. Con esta excepción, la mayoría de las revistas influyentes son publicadas en países desarrollados. La distribución temática de las respuestas y las evaluaciones independientes descartan la posibilidad de que este y los demás resultados resulten de un sesgo entre los científicos consultados por ser de alguna manera próximos a la revista. Temáticamente, se mencionaron especialmente revistas del área marina y ecológica. A diferencia de la ciencia estadounidense, no hay personajes ni libros influyentes que sobresalgan de manera apabullante. Los resultados resaltan la subjetividad de premios y calificaciones en este campo y posiblemente resulten de que no hay tradición de que mujeres y hombres de ciencia locales aparezcan frecuentemente en los medios de comunicación, la poca capacidad de difundir internacionalmente los resultados locales y la insignificante importancia que la cultura iberoamericana concede a la ciencia. También sugieren la necesidad de que las revistas latinoamericanas hagan un esfuerzo para llenar mejor las necesidades del aparato científico regional (buena atención a los autores, un estricto rechazo de los manuscritos de inferior calidad, y una distribución a tiempo y muy amplia de las revistas. La marcada dominancia del sexo masculino puede deberse a que hay pocas mujeres trabajando en este campo o a que ellas no sean percibidas como sobresalientes por razones de inequidad sociocultural.

  9. Discovering indigenous science: Implications for science education

    Indigenous science relates to both the science knowledge of long-resident, usually oral culture peoples, as well as the science knowledge of all peoples who as participants in culture are affected by the worldview and relativist interests of their home communities. This article explores aspects of multicultural science and pedagogy and describes a rich and well-documented branch of indigenous science known to biologists and ecologists as traditional ecological knowledge (TEK). Although TEK has been generally inaccessible, educators can now use a burgeoning science-based TEK literature that documents numerous examples of time-proven, ecologically relevant, and cost effective indigenous science. Disputes regarding the universality of the standard scientific account are of critical importance for science educators because the definition of science is a de facto gatekeeping device for determining what can be included in a school science curriculum and what cannot. When Western modern science (WMS) is defined as universal it does displace revelation-based knowledge (i.e., creation science); however, it also displaces pragmatic local indigenous knowledge that does not conform with formal aspects of the standard account. Thus, in most science classrooms around the globe, Western modern science has been taught at the expense of indigenous knowledge. However, because WMS has been implicated in many of the world's ecological disasters, and because the traditional wisdom component of TEK is particularly rich in time-tested approaches that foster sustainability and environmental integrity, it is possible that the universalist gatekeeper can be seen as increasingly problematic and even counter productive. This paper describes many examples from Canada and around the world of indigenous people's contributions to science, environmental understanding, and sustainability. The authors argue the view that Western or modern science is just one of many sciences that need to be

    Description of an experiment that was conducted, comparing LED lamps and SON-T (high pressure sodium) lamps. In climate rooms with LED (96% red sodium lamps) or SON-T lamps (without daylight), chrysanthemums were cultivated at two light intensities. Although the air temperature was the same in both treatments, the leaf temperature was clearly higher in the case of SON-T as a result of heat radiation. In the case of LED a more round leaves were observed. Plants cultivated under SON-T light developed closed crops much quicker and required a shorter reaction time (10 to 14 days at high and low light intensity). Yet, the harvest weight of the branches was the same. The net leaf photosynthesis was lower in chrysanthemums cultivated under LED lighting compared to plants cultivated under SON-T lighting. This is probably due to long-term cultivation under a spectrum of almost exclusively red light. The differences between SON-T and LED with regard to light color and heat radiation have significant consequences for growth and development. [Dutch] Een experiment is uitgevoerd om LED lampen en SON-T (hogedruk natriumlampen) lampen te vergelijken. In klimaatkamers met LED (96% rood en 4% blauw) of SON-T lampen (zonder daglichttoetreding) werden chrysanten geteeld bij 2 lichtintensiteiten. Hoewel de luchttemperatuur identiek was bij beide behandelingen was de bladtemperatuur duidelijk hoger bij SON-T als gevolg van warmtestraling. Onder LED belichting werd meer 'bol blad' waargenomen. Planten geteeld onder SON-T belichting ontwikkelden sneller een gesloten gewas en hadden een kortere reactietijd (10 tot 14 dagen bij hoge en lage lichtintensiteit). Maar het oogstgewicht van de takken was gelijk. De netto actuele bladfotosynthese was lager bij chrysanten geteeld onder LED belichting vergeleken met planten geteeld onder SON-T belichting. Dit is waarschijnlijk toe te schrijven aan langdurige teelt onder een spectrum met vrijwel alleen rood licht. De verschillen tussen SON

    Science kitsch? The combination of these two words rings like an oxymoron. Science - as the common saying has it - exposes, discovers, tells the truth; kitsch conceals, covers, lies. I think, this "shadow" of science deserves a specific scrutiny, not only because it reflects the altered place and role of science in contemporary "knowledge" society but also because it pinpoints the task of relocating science in the "multicultural" context of postmodernism, with its different epistemic claims. The genre of science kitsch may help to regain credit by working as a probe to detect false pretensions, explanatory exuberance and exaggerations in science.

    Science.gov (United States)

    MacDonald, Anthony Leo

    My study examines the development of forms of knowing that arise when students engage in open-ended explorations involving self-directed design and building involving simple materials. It is grounded in an enactivist theoretical perspective on cognition which holds that the creation of action-thought processes for engaging the world is interwoven with the meanings that are constructed for these experiences. A dynamic conception of persons-acting-in-a-setting is fundamental to an enactivist view of cognition. How is understanding enacted in building activity? How does the shape of a problem emerge? How do students enact meaning and understanding when they experience a high degree of physical engagement in building things? What are some characteristics of an enactive learning/teaching environment? My research settings comprise a range of individual, group and classroom engagements of varying lengths over a three and one-half year period. The first research episode involved two grade eight students in an investigation of Paper Towels. The second four month engagement was in a grade nine science class that culminated in the building of a Solar House. The third grade ten episode involved a one month project to build a Mousetrap Powered Car. A fourth Invent a Machine project was conducted in two grade eight science classes taught by the teacher who participated in the Solar House project. Two students were present in three of the four projects. I interviewed one of these students upon completion of his high school physics courses. I found that building is a form of thinking which develops competency in managing complex practical tasks. A triadic relationship of exploration, planning and acting is present. Practical and procedural understandings emerge as students enter and re-enter self-directed problem settings. Thinking patterns depend on the kinds of materials chosen, the ways they are used, and on how students contextualize the problem. Classroom assessment

    The primary objective was to examine the long-term impact of mother-son incest and positive initial perceptions of sexual abuse experiences on adult male psychosocial functioning. Sixty-seven clinic-referred men with a history of sexual abuse participated. The participants completed self-report measures regarding their current psychosocial functioning and described the nature of their sexual and physical abuse experiences during childhood. Seventeen men reported mother-son incest, and these men endorsed more trauma symptoms than did other sexually abused men, even after controlling for a history of multiple perpetrators and physical abuse. Mother-son incest was likely to be subtle, involving behaviors that may be difficult to distinguish from normal caregiving (e.g., genital touching), despite the potentially serious long-term consequences. Twenty-seven men recalled positive or mixed initial perceptions of the abuse, including about half of the men who had been abused by their mothers. These men reported more adjustment problems than did men who recalled purely negative initial perceptions. Mother-son incest and positive initial perceptions of sexual abuse experiences both appear to be risk factors for more severe psychosocial adjustment problems among clinic-referred men.

    2016-01-01

    Given the costs of multiple mating, why has female polyandry evolved? Utetheisa ornatrix moths are well suited for studying multiple mating in females because females are highly polyandrous over their life span, with each male mate transferring a substantial spermatophore with both genetic and nongenetic material. The accumulation of resources might explain the prevalence of polyandry in this species, but another, not mutually exclusive, possibility is that females mate multiply to increase the probability that their sons will inherit more-competitive sperm. This latter "sexy-sperm" hypothesis posits that female multiple mating and male sperm competitiveness coevolve via a Fisherian runaway process. We tested the sexy-sperm hypothesis by using competitive double matings to compare the sperm competition success of sons of polyandrous versus monandrous females. In accordance with sexy-sperm theory, we found that in 511 offspring across 17 families, the male whose polyandrous mother mated once with each of three different males sired significantly more of all total offspring (81%) than did the male whose monandrous mother was mated thrice to a single male. Interestingly, sons of polyandrous mothers had a significantly biased sex ratio of their brood toward sons, also in support of the hypothesis. © 2015 The Author(s).

    Scientists and engineers constantly face new challenges, despite myriad advances in computing. More sets of data are collected today from earth and sky than there is time or resources available to carefully analyze them. Some problems either don't have fast algorithms to solve them or have solutions that must be found among millions of options, a situation akin to finding a needle in a haystack. But all hope is not lost: advances in technology and the Internet have empowered the general public to participate in the scientific process via individual computational resources and brain cognition, which isn't matched by any machine. Citizen scientists are volunteers who perform scientific work by making observations, collecting and disseminating data, making measurements, and analyzing or interpreting data without necessarily having any scientific training. In so doing, individuals from all over the world can contribute to science in ways that wouldn't have been otherwise possible.

    In contemporary research, the supercomputer now ranks, along with radio telescopes, particle accelerators and the other apparatus of "big science", as an expensive resource, which is nevertheless essential for state of the art research. Supercomputers are usually provided as shar.ed central facilities. However, unlike, telescopes and accelerators, they are find a wide range of applications which extends across a broad spectrum of research activity. The difference in performance between a "good" and a "bad" computer program on a traditional serial computer may be a factor of two or three, but on a contemporary supercomputer it can easily be a factor of one hundred or even more! Furthermore, this factor is likely to increase with future generations of machines. In keeping with the large capital and recurrent costs of these machines, it is appropriate to devote effort to training and familiarization so that supercomputers are employed to best effect.

    This longitudinal study uses a three-generation database involving measures of grandparental and parental alcohol use disorder (AUD), marital aggression and aggression to offspring to predict early and later childhood aggression of third generation offspring. Given the importance of aggressive, undercontrolled behavior in the etiology of alcoholism, the purpose of this study was to construct a statistical model of intergenerational aggression and alcoholism among family members. Participants were a population-based sample of 186 young sons of alcoholics and both biological parents and 120 nonsubstance abusing families and their age-matched sons drawn from the same neighborhoods. Extensive family data were collected at baseline and at 6 years postbaseline. Structural equation modeling evaluated retrospective and prospective relationships between grandparental and parental predictors of the sons' childhood aggression when they were 3-5 and 9-11 years of age. The final model showed that grandparental marital aggression predicted development of parental antisocial behavior, which predicted parental alcoholism and marital aggression and partially mediated level of child aggression among their sons as preschoolers. Significant autostabilities in level of child aggression, parental AUD and marital aggression were present in families over the 6-year interval. Marital aggression was a more important predictor of son's preschool aggression; direct parental aggression to the child was more important at 9-11. Child aggression at 3-5 also was a partial mediator of level of parent-to-child aggression at 9-11. Results indicate continuity of aggression across three generations and also indicate that the child's pathway into risk for later AUD is not simply mediated by parental alcoholism, but is carried by other comorbid aspects of family functioning, in particular aggression.

    Natural scientists from Climate Central and social scientists from Carnegie Mellon University collaborated to develop science communications aimed at presenting personalized coastal flood risk information to the public. We encountered four main challenges: agreeing on goals; balancing complexity and simplicity; relying on data, not intuition; and negotiating external pressures. Each challenge demanded its own approach. We navigated agreement on goals through intensive internal communication early on in the project. We balanced complexity and simplicity through evaluation of communication materials for user understanding and scientific content. Early user test results that overturned some of our intuitions strengthened our commitment to testing communication elements whenever possible. Finally, we did our best to negotiate external pressures through regular internal communication and willingness to compromise.

    Arid Central Asia represents a key region for understanding climate variability and interactions in the Northern Hemisphere. Patterns and mechanisms of Holocene climate change in arid Central Asia are, however, only partially understood. Multi-proxy data combining diatom, ostracod, sedimentological, geochemical and stable isotope analyses from a ca. 6000-year-old lake sediment core from Son Kol (Central Kyrgyzstan) show distinct and repeated changes in species assemblages. Diatom- and ostracod-inferred conductivity shifts between meso-euhaline and freshwater conditions suggest water balance and regime shifts. Organism-derived data are corroborated by stable isotope, mineralogical and geochemical records, underlining that Son Kol was affected by strong lake level fluctuations of several meters. The δ13Ccarb/δ18Ocarb correlation shows repeated switchovers from a closed to an open lake system. From 6000 to 3800 and 3250 to 1950 cal. yr BP, Son Kol was a closed basin lake with higher conductivities, increased nutrient availability and a water level located below the modern outflow. Son Kol became again a hydrologically open lake at 3800 and 1950 cal. yr BP. Comparisons to other local and regional paleoclimate records indicate that these regime shifts were largely controlled by changing intensity and position of the Westerlies and the Siberian Anticyclone that triggered changes in the amount of winter precipitation. A strong influence of the Westerlies ca. 5000-4400, 3800-3250 and since 1950 cal. yr BP enhanced the amount of precipitation during spring, autumn and winter, whereas cold and dry winters prevailed during phases with a strong Siberian Anticyclone and southward shifted Westerlies at ca. 6000-5000, 4400-3800 and 3250-1950 cal. yr BP. Similarities between variations in winter precipitation at Son Kol and records of the predominant NAO-mode further suggest a teleconnection between wet (dry) winter climate in Central Asia and a positive (negative) NAO

    A remarkable scientific result that appears to violate natural law may portend a revolutionary advance in human knowledge. It is, however, more likely an experimental screw up. Error is normal; it can be reduced by repeating measurements and better design of controls, but the success and credibility of science is anchored in a culture of openness. Ideas and observations are freely exposed to independent testing and evaluation by others. What emerges is the book of nature. On its pages we find, if not a simple world, at least an orderly world, in which everything from the birth of stars to falling in love is governed by the same natural laws. These laws cannot be circumvented by any amount of piety or cleverness, they can be understood - with the possible exception of String Theory. For those who elect to work outside the scientific community, errors may go unrecognized. We will examine examples of this, including claims of perpetual motion and cancer caused by cell-phone radiation.

    While alcohol consumption and heavy episodic (binge) drinking are well-established predictors of male-to-male alcohol-related aggression (MMARA), the role of the father-son relationship in MMARA has yet to be explored. This study therefore examined whether fathering by the biological father rather than another father figure, negative fathering, and gender role modeled by the father figure were significant predictors of involvement in MMARA, once drinking frequency and quantity and heavy episodic drinking were controlled for. A total of 121 university students aged 18 to 25 years (M = 20.63, SD = 1.77 years) voluntarily completed the online questionnaire. The only significant predictors of perpetration of MMARA were a more abusive paternal relationship and drinking quantity (number of standard drinks usually consumed when drinking). Negative father-son relationships may play a role in fostering young men's perpetration of MMARA in the barroom context. Copyright © 2013 by the Research Society on Alcoholism.

    This article briefly reviews the history and interplay between decision theory, behavioral decision-making research, and cognitive psychology. The review reveals the increasingly important impact that psychology and cognitive science have on decision science. One of the main contributions of cognitive science to decision science is the development of dynamic models that describe the cognitive processes that underlay the evolution of preferences during deliberation phase of making a decision.

    Summ, Annika; Volpers, Anna-Maria

    2016-10-01

    This article examines the current state of science coverage in German print media. It deals with the following questions: (1) how the main characteristics of science journalism can be described, (2) whether there is a difference between various scientific fields, and (3) how different definitions of science journalism lead to differing findings. Two forms of science coverage were analyzed in a standardized, two-part content analysis of German newspapers (N = 1730 and N = 1640). The results show a significant difference between a narrow and a broad definition of science journalism. In the classic understanding, science journalism is prompted by scientific events and is rather noncritical. Science coverage in a broad sense is defined by a wider range of journalistic styles, driven by non-scientific events, and with a focus on the statements of scientific experts. Furthermore, the study describes the specific role of the humanities and social sciences in German science coverage. © The Author(s) 2015.

  11. Science Olympiad students' nature of science understandings

    Philpot, Cindy J.

    2007-12-01

    Recent reform efforts in science education focus on scientific literacy for all citizens. In order to be scientifically literate, an individual must have informed understandings of nature of science (NOS), scientific inquiry, and science content matter. This study specifically focused on Science Olympiad students' understanding of NOS as one piece of scientific literacy. Research consistently shows that science students do not have informed understandings of NOS (Abd-El-Khalick, 2002; Bell, Blair, Crawford, and Lederman, 2002; Kilcrease and Lucy, 2002; Schwartz, Lederman, and Thompson, 2001). However, McGhee-Brown, Martin, Monsaas and Stombler (2003) found that Science Olympiad students had in-depth understandings of science concepts, principles, processes, and techniques. Science Olympiad teams compete nationally and are found in rural, urban, and suburban schools. In an effort to learn from students who are generally considered high achieving students and who enjoy science, as opposed to the typical science student, the purpose of this study was to investigate Science Olympiad students' understandings of NOS and the experiences that formed their understandings. An interpretive, qualitative, case study method was used to address the research questions. The participants were purposefully and conveniently selected from the Science Olympiad team at a suburban high school. Data collection consisted of the Views of Nature of Science -- High School Questionnaire (VNOS-HS) (Schwartz, Lederman, & Thompson, 2001), semi-structured individual interviews, and a focus group. The main findings of this study were similar to much of the previous research in that the participants had informed understandings of the tentative nature of science and the role of inferences in science, but they did not have informed understandings of the role of human imagination and creativity, the empirical nature of science, or theories and laws.

    The aim of this study was to explore how sport medicine and science practitioners manage their emotions through emotional labor when engaging in professional practice in elite sport. To address the research aim a semistructured interview design was adopted. Specifically, eighteen professional sport medicine and science staff provided interviews. The sample comprised sport and exercise psychologists (n=6), strength and conditioning coaches (n=5), physiotherapists (n=5), one sports doctor and one generic sport scientist. Following a process of thematic analysis, the results were organized into the following overarching themes: (a) factors influencing emotional labor enactment, (b) emotional labor enactment, and (c) professional and personal outcomes. The findings provide a novel contribution to understanding the professional demands faced by practitioners and are discussed in relation to the development of professional competencies and the welfare and performance of sport medics and scientists. © 2017 John Wiley & Sons A/S.

    Knowledge about past Asian climate variability and particularly teleconnections between the Westerlies in arid Central Asia and the Monsoon on the Tibetan Plateau is still limited. To reconstruct the Westerlies intensity during the Holocene in arid Central Asia and its effect on vegetation dynamics, we compared the sediment records from alpine lakes Son Kol (273 km2; 13 m depth) and Chatyr Kol (170 km2; 20 m depth), located in the central Tien Shan mountain range (Kyrgyzstan). Both sites differ in the mean annual amount of precipitation received (Son Kol: 550 mm; Chatyr Kol: 260 mm), but show identical recent catchment vegetation (montane grassland). To find out, whether the precipitation primarily causes differences in sedimentary organic matter accumulation, we investigated the distribution of n-alkanes in recent surface sediments from both lakes. The distribution of these biomarkers in Lake Son Kol is dominated by higher input of terrestrial plant material, whereas the one of Lake Chatyr Kol is characterized by mixed input of terrestrial and aquatic material. Additionally, we investigated the n-alkane distributions and compound-specific δD values of radiocarbon-dated sediment cores from Son Kol (core length: 154 cm), dating back to 6000 years BP, and from Chatyr Kol (core length: 625 cm), which dates back to the early Holocene. The combination of terrestrial and aquatic alkane-specific δD values can be used to determine changes of relative humidity. A generally stable n-alkane composition and relatively high amounts of terrestrial biomarkers within the sediments of Lake Son Kol display relatively stable climatic conditions for organic matter production during the mid-to late Holocene. Throughout the record, depleted δD values (-180 ‰) of terrestrial n-alkanes prevail, only periodically interrupted by phases with enriched values (-140 ‰). This suggests a predominance of generally wet conditions due to the influence of the Westerlies with only short

    Early conceptions of the public understanding of science suffered from a narrow framing of what science means and a presumption that science is divided from its publics by walls of ignorance and indifference. Those assumptions amplified misunderstanding and led to faulty policies. It is time to reopen each element in the term "public understanding of science" to renewed reflection. This journal can advance that goal by encouraging research on actual rather than imagined public responses to science, on representations of science in the public sphere, and on interactions between science, technology and society.

    To look for same-sex (gender assortative) association of body mass index (BMI) in healthy trios (mother, father and child) from a contemporary birth cohort, which might imply shared environment rather than shared genes because selective mother-daughter and father-son gene transmission is not a common Mendelian trait. Prospective (longitudinal) cohort study with four annual time points, from 5 to 8 years. 226 healthy trios from a 1995 to 1996 birth cohort randomly selected in the city of Plymouth, UK. Average BMI of the two parents and maternal/paternal BMI separately related to the BMI-SDS (standard deviation score) of all offspring and to the BMI-SDS of the sons and the daughters separately. There were big differences in BMI-SDS among the daughters grouped according to mothers' category of BMI (effect size 1.37 SDS), but not their sons (effect size 0.16 SDS, gender interaction Pfathers' BMI (effect size 1.28 SDS), but not their daughters (effect size 0.17, gender interaction P=0.02). Children whose same-sex parents were of normal weight, weighed either close to (girls+0.20 BMI-SDS) or less than (boys,-0.34 BMI-SDS) children of 20 years ago, and did not change from 5 to 8 years. In contrast, the risks of obesity at 8 years were 10-fold greater (girls 41%, Pobese. Longitudinal linear mixed effects (multilevel) modelling showed a marked influence of maternal and paternal BMI on the rate of weight gain, which was unaffected by birth weight of the child. We report perhaps the largest effect sizes so far recorded in childhood obesity. Childhood obesity today seems to be largely confined to those whose same-sex parents are obese, and the link does not seem to be genetic. Parental obesity, like smoking, might be targeted in the interests of the child.

    A partir des données de 1991 et 1992 du détecteur ALEPH au LEP, nous obtenons un signal provenant du méson Bos en étudiant ses désintégrations semi-leptoniques en un méson D-s et un lepton de signe opposé. L'optimisation du rejet des bruits de fond et de l'efficacité de sélection utilise, entre autres, la mesure d'ionisation des particules chargées. Pour déterminer la durée de vie du B0s, il est nécessaire de mesurer l'énergie de chaque candidat. Cette énergie est la somme des énergies des particules chargées D-s et lepton et de l'énergie manquante, incluant une correction de masse des hémisphères, identifiée à l'énergie du neutrino. Nous utilisons cette mesure d'énergie manquante pour réduire les bruits de fond et mesurer la probabilité Ps qu'un quark beau produise un méson B0s lors de l'hadronisation: Ps = P (b→Bs) = (13,2 ± 4,3 ± 4,4)%. Pour la mesure de la durée de vie du B0s, nous reconstruisons les vertex de désintégration du D-s et du B0s à partir de leurs produits d...

    La gran cantidad de gerentas o fundadoras de grandes compañías, profesoras, investigadoras, directoras de laboratorios o centro de investigación, becarias, parecen echar por tierra cualquier suposición acerca de discriminación por género en el sector del software y servicios informáticos. Las TICs son abordadas indistintamente por ambos géneros, que las utilizan, las disfrutan y se apropian de ellas. No obstante a la hora de elegir una carrera universitaria, las TICs no forman parte de las pr...

    Full Text Available OBJETIVO: verificar o número de crianças, entre 5:0 e 11:6 anos, com e sem Transtorno Fonológico, falantes do Português Brasileiro que imitaram corretamente os sons líquidos no teste de estimulabilidade considerando cada uma das vogais subsequentes. MÉTODOS: a estimulabilidade foi medida por uma prova de imitação de 63 sílabas com os sons com as sete vogais orais, em três repetições. Foi analisada a porcentagem de sujeitos que produziu corretamente os sons em função da vogal subsequente. RESULTADOS: o foi o som com mais produções corretas, independente da vogal subsequente; o foi melhor produzido com as vogais subsequentes [ε, ó], parecendo ser a altura da língua em posição média-baixa facilitadora da produção desse som; o foi melhor produzido com as vogais subsequentes arredondadas [o, ó, u] evidenciando que o gesto articulatório de arredondamento dos lábios facilita a produção deste som, assim como a posição média-alta e posterior da língua. CONCLUSÃO: as vogais subsequentes aos sons líquidos estudados evidenciam influências em suas produções, de forma a facilitá-las.PURPOSE: to check the number of children, between 5:0 and 11:6-year old, with and without Phonological Disorder, Brazilian Portuguese speaking children that imitated correctly the liquid sounds in the stimulability test considering each one of the subsequent vowels. METHODS: the stimulability was measured in syllable imitation of 63 syllables with the sounds with seven oral vowels. We analyzed the percentage of subjects that produced correctly the sounds as a function of the subsequent vowel. RESULTS: the was the sound with more correct productions, independent of the sequent vowel; the was better produced with the vowels [ε, ó], and it seems that the medium-lower position height of the tongue is make easier the production of this sound; the was better produced with the vowels [o, ó, u], it seems that the round position of the lips

    El presente trabajo propone estudiar la irrupción del discurso lírico tal como lo define Susana Reisz de Rivarola en Romance Sonámbulo de Federico García Lorca. Si bien Romancero Gitano se adscribe en la vanguardia estética española, es el género tradicional romance lo que estructura el poemario junto con varios elementos que articulan un diálogo entre lírica moderna y tradicional. Según Karlheinz Stierle el discurso lírico se caracteriza por la ruptura de la linealidad y la multiplicación de...

    2015-01-01

    Cet article s’interroge sur les raisons pour lesquelles, dans le Banquet de Platon, Socrate prononce son éloge d’Eros sous la forme d’un dialogue rapporté qui met en scène deux personnages : Diotime et Socrate encore jeune homme. Je montre d’abord que chaque interlocuteur de ce dialogue enchâssé se présente comme une synthèse des deux personnages du dialogue cadre (Agathon et Socrate adulte, devenu un philosophe accompli) : Diotime, c’est le dialecticien Socrate vu par les yeux d’un poète et ...

    2002-01-01

    In his narrative the author of this Gospel starkly emphasizes the humiliation and suffering of Jesus as the Son of Man (i.a. 10:45). In doing so, Mark emphasizes that Jesus’ way to be the Christ is the way of suffering. In several instances Mark describes Jesus’ disciples’ ignorance of this fact. Special focus is placed on the ignorance of Peter when confessing Jesus as the Christ. The point of departure for this article is that the Gospel of Mark was written to a specific believing communit...

    Art and science are separated by a very large distance nowadays. Long ago, e.g. in Renaissance, or even earlier, in classic Greece and Rome, or still earlier in Egypt or Mesopotamia, arts and sciences were united. Today they seem to go separate paths: science for the industry, arts for the gallery. Holography is an exception: no art without science, but also no science without art.

    In science, the natural science is being used to study the nature surrounding us. As a rule, the methods of natural science are based on strong scientific evidence that would either prove or disprove the scientific hypothesis. Therefore, the natural science is considered to be pretty much unilateral; there is very little uncertainty within the evidence of natural science. Doing this project has taught us the opposite. The basic semester requirement is to write a project “about science” and...
