Le luxe publié au dix-huitième siècle : questions de formes

Full Text Available Parmi la multitude d’ouvrages qui traitent du luxe au xviiie siècle, deux  titres se signalent par une similitude frappante de contenu : Le comte de Valmont de Gérard et Le monarque accompli de Lanjuinais, publiés en 1774. Leur critique du luxe s’appuie en effet sur les mêmes citations, les mêmes morceaux célèbres, les mêmes formules frappantes de Montesquieu, Rousseau ou Helvétius. à se pencher sur les conditions de publication et les profils des deux auteurs, on se rend compte qu’il s’agit pourtant de deux ouvrages se situant aux antipodes l’un de l’autre au sein de l’espace de l’imprimé du xviiie siècle, mais aussi dans l’historiographie, roman apologétique s’inscrivant dans l’orthodoxie d’Ancien Régime pour l’un, « livre philosophique » considéré comme exemplaire d’une critique du luxe subversive pour l’autre. C’est en analysant de plus près les dispositifs d’écriture et l’usage des citations que l’on saisit la production de sens très contrastés à partir d’un matériau similaire.The Publication of Luxury in the Eighteenth Century: a Question of FormAmong the many eighteenth-century works on luxury, two stand out for their striking resemblances: Le comte de Valmont by Gérard and Le monarque accompli by Lanjuinais, both published in 1774. Both criticize luxury by referring to the same quotations, the same famous passages, the same salient sentences by Montesquieu, Rousseau or Helvétius. Nevertheless, when one examines these writers’ publishing conditions and authorial figures, one is forced to acknowledge that these books are completely different and belong to distinct print cultures and historiographic traditions: one is an epistolary novel typical of the Old Regime’s orthodoxy; the other is a “philosophical book” that exemplifies more subversive critiques of luxury.

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.

SO(N) reformulated link invariants from topological strings

Borhade, Pravina; Ramadevi, P.

2005-01-01

Large N duality conjecture between U(N) Chern-Simons gauge theory on S 3 and A-model topological string theory on the resolved conifold was verified at the level of partition function and Wilson loop observables. As a consequence, the conjectured form for the expectation value of the topological operators in A-model string theory led to a reformulation of link invariants in U(N) Chern-Simons theory giving new polynomial invariants whose integer coefficients could be given a topological meaning. We show that the A-model topological operator involving SO(N) holonomy leads to a reformulation of link invariants in SO(N) Chern-Simons theory. Surprisingly, the SO(N) reformulated invariants also has a similar form with integer coefficients. The topological meaning of the integer coefficients needs to be explored from the duality conjecture relating SO(N) Chern-Simons theory to A-model closed string theory on orientifold of the resolved conifold background

Son preference in a rural village in North Vietnam.

Science.gov (United States)

Bélanger, Danièle

2002-12-01

This article explores the continuing preference for sons in the context of low fertility in Vietnam. Although the total fertility rate for Vietnam declined from 6.0 children per woman of reproductive age in 1979 to 2.2 children in 1998, demographic evidence shows that son preference remains strong and influences contraceptive and fertility behavior. This study examines the underlying factors for son preference in a rural village in North Vietnam. The methodology includes focus-group discussions, an in-depth study of 25 families, and ethnographic observation. Results indicate that sons are highly desired for their social, symbolic, and economic value. In spite of four decades of socialist policies aimed at reducing gender-based inequalities and at weakening the patriarchal kinship system, the desire for sons continues to drive the family-building process. The article also indicates a gap between discourse and social practice with respect to roles assigned to children on the basis of their sex.

Maternal overweight and obesity in pregnancy has been associated with earlier age of menarche in daughters as well as reduced semen quality in sons. We aimed at investigating pubertal development in sons born by mothers with a high body mass index (BMI). The study included 2522 sons of mothers...... indicators of pubertal development, results also indicated earlier pubertal development among sons of obese mothers. After excluding sons of underweight mothers in a subanalysis, we observed an inverse trend between maternal pre-pregnancy BMI and age at regular shaving, acne and first nocturnal emission....... In conclusion, maternal pre-pregnant obesity may be related to earlier timing of pubertal milestones among sons. More research, preferably based on prospectively collected information about pubertal development, is needed to draw firm conclusions....

Full Text Available 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. O. 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.

The Transmission of Parenting from Fathers to Sons

Hofferth, Sandra L.; Pleck, Joseph H.; Vesely, Colleen K.

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

Parent-son decision-making about human papillomavirus vaccination: a qualitative analysis

Directory of Open Access Journals (Sweden)

Alexander Andreia B

2012-12-01

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

Coupling coefficients of SO(n) and integrals involving Jacobi and Gegenbauer polynomials

International Nuclear Information System (INIS)

Alisauskas, Sigitas

2002-01-01

The expressions for the coupling coefficients (3j-symbols) for most degenerate (symmetric) representations of orthogonal groups SO(n) in a canonical basis (with SO(n) restricted to SO(n-1) and different semicanonical or tree bases (with SO(n) restricted to SO(n')xSO(n''), n'+n''=n) are considered, respectively, in context of integrals involving triplets of the Gegenbauer and the Jacobi polynomials. Since the directly derived triple-hypergeometric series do not reveal the apparent triangle conditions of the 3j-symbols, they are rearranged, using their relation with semistretched isofactors of the second kind for the complementary chain Sp(4) contains SU(2)xSU(2) and analogy with the stretched 9j coefficients of SU(2), into formulae with more rich limits for summation intervals and obvious triangle conditions. The isofactors of class-one representations of orthogonal groups or class-two representations of unitary groups (and, of course, the related integrals involving triplets of the Gegenbauer and the Jacobi polynomials) turn into double sums in the cases of canonical SO(n) contains SO(n-1) or U(n) contains U(n-1) and semicanonical SO(n) contains SO(n-2)xSO(2) chains, as well as into the 4 F 3 (1) series under more specific conditions. Some ambiguities of the phase choice of the complementary group approach are adjusted, as well as problems with an alternating sign parameter of SO(2) representations in the SO(3) contains SO(2) and SO(n) contains SO(n-2)xSO(2) chains.

Benefits of Self-Organizing Networks (SON for Mobile Operators

Directory of Open Access Journals (Sweden)

Olav Østerbø

2012-01-01

Full Text Available Self-Organizing Networks (SON is a collection of functions for automatic configuration, optimization, diagnostisation and healing of cellular networks. It is considered to be a necessity in future mobile networks and operations due to the increased cost pressure. The main drivers are essentially to reduce CAPEX and OPEX, which would otherwise increase dramatically due to increased number of network parameters that has to be monitored and set, the rapidly increasing numbers of base stations in the network and parallel operation of 2G, 3G and Evolved Packet Core (EPC infrastructures. This paper presents evaluations on the use of some of the most important SON components. Mobile networks are getting more complex to configure, optimize and maintain. Many SON functions will give cost savings and performance benefits from the very beginning of a network deployment and these should be prioritized now. But even if many functions are already available and can give large benefits, the field is still in its infancy and more advanced functions are either not yet implemented or have immature implementations. It is therefore necessary to have a strategy for how and when different SON functions should be introduced in mobile networks.

The eukaryotic RNA splicing machinery is dedicated to the daunting task of excising intronic sequences on the many nascent RNA transcripts in a cell, and in doing so facilitates proper translation of its transcriptome. Notably, emerging evidence suggests that RNA splicing may also play direct roles in maintaining genome stability. Here we report the identification of the RNA/DNA-binding protein SON as a component of spliceosome that plays pleiotropic roles during mitotic progression. We found that SON is essential for cell proliferation, and that its inactivation triggers a MAD2-dependent mitotic delay. Moreover, SON deficiency is accompanied by defective chromosome congression, compromised chromosome segregation and cytokinesis, which in turn contributes to cellular aneuploidy and cell death. In summary, our study uncovers a specific link between SON and mitosis, and highlights the potential of RNA processing as additional regulatory mechanisms that govern cell proliferation and division. © 2010 Landes Bioscience

THE MOTIF OF THE PRODIGAL SON IN IVAN TURGENEV'S NOVELS

Directory of Open Access Journals (Sweden)

Valentina Ivanovna Gabdullina

2013-11-01

Full Text Available The author questions the perception of Ivan Turgenev as a “non- Christian writer” and studies the problem of the prodigal son motif functioning in a series of his novels. In his novels, Turgenev pictured different phases of the archetypal story, originating from the Gospel parable of the prodigal son. In the novel Rudin he depicted the phase of spiritual wanderings of the hero who had lost touch with his native land — Russia. In his next novels (Home of the Gentry, Fathers and Sons and Smoke, after leading his hero in circles and sending him back to his paternal home, Turgenev reconstructs the model of human behavior, represented in the parable, thereby recognizing the immutability of the idea formalized in the Gospel. The motif of the return to Russian land gets its completion in Turgenev's last novel Virgin Soil, in which the author paradoxically connects the Westernist idea with the Gospel imperative. Solomin, the son of a deacon, sent by his wise father out to Europe “to get education”, studies in England, masters the European knowledge and returns back “to his native land” to establish his own business in inland Russia. Thus, a series of Turgenev's novels, in which he portrayed different phases of social life, are interlinked with the motif of the prodigal son, who is represented by novels' main characters.

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 pCommunication campaigns may be able to target these beliefs to increase parents' and sons' willingness to seek HPV vaccination.

Supersymmetric vector multiplets in nonadjoint representations of SO(N)

International Nuclear Information System (INIS)

Nishino, Hitoshi; Rajpoot, Subhash

2007-01-01

In the conventional formulation of N=1 supersymmetry, a vector multiplet is supposed to be in the adjoint representation of a given gauge group. We present a new formulation with a vector multiplet in the nonadjoint representation of SO(N) gauge group. Our basic algebra is [T I ,T J ]=f IJK T K , [T I ,U i ]=-(T I ) ij U j , [U i ,U j ]=-(T I ) ij T I , where T I are the generators of SO(N), while U i are the new ''generators'' in certain nonadjoint real representation R of SO(N). We use here the word generator in the broader sense of the word. Such a representation can be any real representation of SO(N) with the positive definite metric, satisfying (T I ) ij =-(T I ) ji and (T I ) [ij| (T I ) |k]l ≡0. The first nontrivial examples are the spinorial 8 S and conjugate spinorial 8 C representations of SO(8) consistent with supersymmetry. We further couple the system to chiral multiplets and show that a Higgs mechanism can give positive definite (mass) 2 to the new gauge fields for U i . We show an analogous system working with N=1 supersymmetry in 10D, and thereby N=4 system in 4D interacting with extra multiplets in the representation R. We also perform superspace reformulation as an independent confirmation

General properties of the SO(n) groups are examined, with emphasis on the usefulness of the Gel'fand-Zetlin basis for explicit calculations. The SO(n) representations containing a vector stabilized by subgroups of the type S[O(n-p) x O(p)], SU(k) x U(1) or SU(k) if n=2k, are characterized in view of selecting Higgs representations in SO(n) gauge models. Some useful properties of the SU(n) Gel'fand-Zetlin basis are given in the appendices

In the Pursuit of Sons: Additional Births or Sex-Selective Abortion in Pakistan?

Science.gov (United States)

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.

My Son 22.10.11

Rebecca Baillie

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.

Son Preference and Family Limitation in Pakistan: A Parity- and Contraceptive Method-Specific Analysis.

Science.gov (United States)

Channon, Melanie Dawn

2017-09-01

Son preference exerts a strong influence over contraceptive and fertility decisions in many South Asian countries. In Pakistan, where fertility remains high and contraceptive use low, research on son preference has been limited. Data from Pakistan Demographic and Health Surveys conducted in 1990-1991, 2006-2007 and 2012-2013 were used to examine potential indicators and outcomes of son preference. Descriptive analyses looked at sex composition preferences of men and women, as well as the sex ratio at last birth. Multivariate logistic regression analyses examined parity progression by birth order, while multinomial logistic regression was used to identify associations between sex composition and use of permanent, temporary and traditional contraceptive methods. Parity progression and choice of contraceptive method are increasingly associated with the sex composition of children. Many respondents wanted at least two sons, though most also wanted at least one daughter. Analyses suggest that the prevalence of modern contraceptive use among parous women would have been 19% higher in 2012-2013 in the absence of son preference. Permanent method use was extremely low among women with no sons and increased significantly with number of sons. The association between number of sons and use of temporary methods was weaker, while son preference had little relationship with traditional method use. The association of son preference with parity progression and modern contraceptive use has become stronger in Pakistan. Continuation of the fertility transition may be difficult unless the degrees of differential stopping behavior and differential contraceptive use decline.

Having a Son Promotes Clean Cooking Fuel Use in Urban India: Women's Status and Son Preference

Urban Indian households with a male first child are approximately 2 percentage points more likely to use clean cooking fuel than comparable households with a female first child. Given Indian son preference, there are at least two mechanisms by which child sex could affect fuel choice: by improving the intrahousehold status of women, who bear more of the costs of traditional fuels, or by presenting an opportunity to invest in children's health, in the context of a preference for healthier boys...

The institutionalization of Jesus' charismatic authority: "Son of Man" as case study1

Directory of Open Access Journals (Sweden)

Yolanda Dreyer

2000-12-01

Full Text Available This article argues that Jesus used the expression "son of man" not in a titular way, but genetically, meaning "humankind". This use of "son of man" developed into a titular usage in which Jesus is identified with "Son of Man". The study shows that Jesus' use of the expression "son of man" should be understood in the context of the "little tradition" which was reinterpreted in terms of the "great tradition" in a titular way. It is argued that this transition from "litle tradition" to "great tradition"can be seen as "false attribution". After Jesus' death when his followers reorganized themselves into a cultic community, they gave Jesus the position "founder of the cult". They did this by making use of honorary titles. The use of the title "Son of Man" for Jesus is interpreted in terms of the social theory of the institutionalization of charismatic authority. The focus is on the title "Son of Man" as it appears in legal sayings or church rules, wisdom sayings and prophetic and apocalyptic sayings.

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.

The experience of sons caring for a parent with dementia.

McDonnell, Eilis; Ryan, Assumpta A

2014-11-01

This study explored the experiences of sons caring for a parent with dementia. Individual, semi-structured interviews were conducted with a purposeful sample of sons (n = 13) in a rural part of Ireland. Interviews were audiotaped, transcribed verbatim and analysed for common themes. The key themes that emerged were 'the parental bond', 'a binding role', 'coordinating care and support' and a 'getting on with it' approach to care. The study highlighted the commitment of sons to their caregiving role and the strong sense of duty that motivated them to provide care. The findings suggested that while many aspects of the caregiving experience such as lack of information and support are gender neutral, there are differences in the caregiving experiences of men and women in how they view their relationship with their parent and in the management of their caregiving role that merit further investigation. © The Author(s) 2013 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

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.

Human embryonic stem cells (hESCs) harbour the ability to undergo lineage-specific differentiation into clinically relevant cell types. Transcription factors and epigenetic modifiers are known to play important roles in the maintenance of pluripotency of hESCs. However, little is known about regulation of pluripotency through splicing. In this study, we identify the spliceosome-associated factor SON as a factor essential for the maintenance of hESCs. Depletion of SON in hESCs results in the loss of pluripotency and cell death. Using genome-wide RNA profiling, we identified transcripts that are regulated by SON. Importantly, we confirmed that SON regulates the proper splicing of transcripts encoding for pluripotency regulators such as OCT4, PRDM14, E4F1 and MED24. Furthermore, we show that SON is bound to these transcripts in vivo. In summary, we connect a splicing-regulatory network for accurate transcript production to the maintenance of pluripotency and self-renewal of hESCs.

on occupation and cryptorchidism. METHODS: The cohort consisted of >600 000 boys born in Denmark from 1980-2007 with a parent in employment during pregnancy. These boys were followed for cryptorchidism from 1980-2009 comparing risks among sons of horticultural workers and farmers with sons of parents in other...... occupations. Hazard ratios (HR) and 95% confidence intervals (95% CI) were estimated using Cox regression adjusting for parental age, birth years, parity, and geographical region. RESULTS: Sons of maternal farmers were at increased risk of cryptorchidism (157 cases; HR 1.31, 95% CI 1.12-1.53) compared to boys...... 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...

African-American Fathers' Perspectives on Facilitators and Barriers to Father-Son Sexual Health Communication.

Randolph, Schenita D; Coakley, Tanya; Shears, Jeffrey; Thorpe, Roland J

2017-06-01

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.

2015-04-01

The Habermasian concept of 'interest' has had a profound effect on the characterization of scientific disciplines. 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.

Girl adoption in China-A less-known side of son preference.

Science.gov (United States)

Chen, Yuyu; Ebenstein, Avraham; Edlund, Lena; Li, Hongbin

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.

Reliability of P mode event classification using contemporaneous BiSON and GOLF observations

We carried out a comparison of the signals seen in contemporaneous BiSON and GOLF data sets. Both instruments perform Doppler shift velocity measurements in integrated sunlight, although BiSON perform measurements from the two wings of potassium absorption line and GOLF from one wing of the NaD1 line. Discrepancies between the two datasets have been observed. We show,in fact, that the relative power depends on the wing in which GOLF data observes. During the blue wing period, the relative power is mugh higher than in BiSON datasets, while a good agreement has been observed during the red period.

Burns, Jade C; Caldwell, Cleopatra H

2016-02-01

Research on communication between resident and nonresident African American fathers and their sons about sex has been understudied. The purpose of this study is to determine the influence of parenting variables, specifically, racial socialization and father involvement on nonresident African American father-son communication about sex. Data for this study are from the Fathers and Sons Project. This intervention study is designed to enhance relationships between nonresident African American fathers and their 8-12 year old sons and to prevent risky health behaviors among sons. The present study is based on 345 African American boys who completed baseline face-to-face interviews. The average age of the sons was 10.2 years old (SD = 1.4), with an average of two siblings (SD = 1.53). Age and sons' perceptions of more parental monitoring by their fathers were predictive of increased communication about sex. Racial socialization messages explained additional variance in communication about sex above other parenting variables and controls. Findings suggest when working with African American families, providers who counsel parents, and in particular provide outreach to fathers regarding communication about sex, are in a unique position to enhance parenting communication skills about sexuality. ©2015 American Association of Nurse Practitioners.

Associations Between Fathers' and Sons' Sexual Risk in Rural Kenya: The Potential for Intergenerational Transmission.

Giusto, Ali M; Green, Eric P; Puffer, Eve S

2017-08-01

Despite high rates of HIV in areas of Sub-Saharan Africa and men's role in driving the epidemic, little is known about whether or how sexual risk-both behaviors and beliefs-may be passed down through generations of males. This study examined associations between sexual risk behaviors and sex-related beliefs of adolescent males and those of their male caregivers in Kenya, as well as the potential moderating effects of parenting characteristics and father-son relationship quality. Cross-sectional linear regression analysis was applied to baseline data from a trial of a family- and church-based intervention for families in rural Kenya that followed a stepped-wedge cluster randomized design. Our subsample consisted of 79 male caregiver and son (aged 10-16 years) dyads. Results demonstrated a direct relationship between fathers' and sons' sex-related beliefs that was not moderated by parenting or quality of father-son relationship. Parenting/relationship characteristics did moderate the relationship between fathers' and sons' sexual behavior; if fathers did not engage in high-risk sex and exhibited more positive parenting/higher relationship quality, their sons were less likely to be sexually active. Among fathers having high-risk sex, parenting was unrelated to sons' behavior except at very high levels of positive parenting/relationship quality; at these levels, sons were actually more likely to have had sex. Findings support recommendations to include male caregivers in youth HIV prevention efforts, potentially by targeting fathers' parenting strategies and their individual risk.

Has Their Son Been Vaccinated? Beliefs About Other Parents Matter for Human Papillomavirus Vaccine.

Science.gov (United States)

Schuler, Christine L; Coyne-Beasley, Tamera

2016-07-01

The goal of this study was to determine if parents' beliefs about social norms of human papillomavirus (HPV) vaccination for sons were associated with knowledge of HPV, intention to vaccinate sons, or beliefs about side effects. A cross-sectional, survey-based study of parents with sons was performed in 2010. Fisher's exact tests were used to examine associations between demographics and responses about social norms. Multivariate logistic regression models examined beliefs about social norms of male HPV vaccination and primary outcomes. Few parents agreed that others were vaccinating sons (n = 31/267, 12%), including 1% responding strongly agree and 11% responding agree. Most parents, 52%, disagreed that others were vaccinating (40% disagree, 11% strongly disagree), and 37% chose prefer not to answer regarding others' vaccination practices. Hispanic parents and those with a high school education or less were significantly more likely to choose prefer not to answer than their respective counterparts regarding vaccination norms. In multivariate models, parents agreeing others were vaccinating sons had greater odds of having high knowledge of HPV (adjusted odds ratio [aOR] high vs low knowledge 3.15, 95% confidence interval [CI] 1.13, 8.77) and increased intention to vaccinate sons (n = 243, aOR = 4.41, 95% CI = 1.51, 12.89). Beliefs about side effects were not significantly associated with beliefs about social norms. Parents' beliefs about others' vaccination practices are important with regard to knowledge of HPV and intention to vaccinate sons. Studying how various public messages about HPV vaccine may influence normative beliefs could be relevant to improving vaccination coverage. © The Author(s) 2015.

Andrew Wyeth and N.C. Wyeth: a psychodynamic perspective on father and son.

Science.gov (United States)

Shaw, Jon A

2013-01-01

This paper examines the relationship between two extraordinary artists, father and son--N.C. Wyeth (1882-1945) and Andrew Wyeth (1917-2009)--and their art. N.C. Wyeth, the father, the most famous illustrator of his day, painted scenes full of drama and action, often of men engaged in violent life and death struggles. N.C. was unable to separate from his powerful mother and yearned for his iconic father. He thought himself an artistic failure and dedicated himself to raising his children to be geniuses. The youngest son, Andrew Wyeth, who lived a "secret life," painted scenes often characterized by pathos: bleak and barren landscapes, leaden skies, tire tracks, gray framed houses, desiccated fields, and circling buzzards. In the father-son relationship, we often seen three themes perpetuated developmentally: (1) the son's identification with the innermost conflicts of his father; (2) the yearning for the iconic father of his youth; and (3) a continuation and disavowal of his father's life. These themes are played out in the relationship between Andrew Wyeth and his father.

Older Parents Benefit More in Health Outcome From Daughters' Than Sons' Emotional Care in China.

To examine whether older parents in China would benefit more from daughters' care than from sons' emotional care. Analysis of the unique data sets of the Chinese Longitudinal Healthy Longevity Survey conducted in 2002, 2005, and 2008-2009 in 22 provinces. As compared with having son(s), having daughter(s) is significantly more beneficial at older ages in China, with regard to maintaining higher cognitive capacity and reducing mortality risk. Such daughter advantages in providing emotional care to older parents are more profound among the oldest-old aged 80+ as compared with the young-old aged 65 to 79 and surprisingly more profound in rural areas as compared with urban areas, even though son preference is much more common among rural residents. We describe how educational campaigns aimed at informing the public about the benefits of daughter(s) for older parents' health outcome could help promote gender equality and reduce traditional son preference, especially in rural China.

This paper reports experimental and modeling results of SON68 glass / magnetite interactions while in contact with synthetic groundwater from a clay environment. It is shown that magnetite enhances glass alteration, first by the sorption of Si released from the glass onto magnetite surfaces, then by a second process that could be the precipitation of an iron silicate mineral or the transformation of magnetite into a more reactive phase like hematite or goethite. This study globally suggests a detrimental effect of magnetite on the long-term durability of nuclear glass in geological disposal conditions. (authors)

Full Text Available Night Photograph (1993, le premier recueil de poèmes de Lavinia Greenlaw, se présente comme un prisme qui réfracterait les lois scientifiques dans l’espoir de révéler une vérité, une réalité, ou peut-être même la face cachée de la lune. Ce que l’artiste met en scène, donc, oscille entre le connu et la superstition, entre l’abstraction de la science et la tangibilité de l’art.Traditionnellement, la voix de la science est masculine. Même si Lavinia Greenlaw ne se considère pas engagée dans une démarche féministe, ses poèmes, consciemment ou non, offrent une perspective particulière de  la question du genre. En effet, six ans avant que Carol Ann Duffy ne publie son recueil The World’s Wife (1999, le poème ‘Galileo’s Wife’ de Lavinia Greenlaw explorait déjà le besoin de réinvestir l’Histoire des hommes avec les histoires des femmes.La préoccupation centrale de l’œuvre de Greenlaw est le besoin qu’ont les êtres humains de cartographier le monde et d’en dégager du sens. Pour satisfaire ce besoin de repérage dans l’espace, Galilée, cet homme de l’abstraction, envoie sa femme découvrir l’extrémité  de la Terre. De retour, remplie de la beauté de ses expériences, la femme de Galilée annonce à son mari que le monde est rond. Cependant  Galilée n’accepte pas la découverte de son épouse et continue à enseigner la vérité reçue masculine. Ainsi s’opposent la force démystifiante de l’art et la force mystifiante de la science. Les poèmes de Lavinia Greenlaw tentent de résoudre le conflit qui oppose ces deux notions et poussent la pensée empirique dans ses retranchements. Cet article considérera comment l’exactitude de la science peut s’incarner comme le miracle de l’art.

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.

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.

The Putative Son's Attractiveness Alters the Perceived Attractiveness of the Putative Father.

Science.gov (United States)

Prokop, Pavol

2015-08-01

A body of literature has investigated female mate choice in the pre-mating context (pre-mating sexual selection). Humans, however, are long-living mammals forming pair-bonds which sequentially produce offspring. Post-mating evaluations of a partner's attractiveness may thus significantly influence the reproductive success of men and women. I tested herein the theory that the attractiveness of putative sons provides extra information about the genetic quality of fathers, thereby influencing fathers' attractiveness across three studies. As predicted, facially attractive boys were more frequently attributed to attractive putative fathers and vice versa (Study 1). Furthermore, priming with an attractive putative son increased the attractiveness of the putative father with the reverse being true for unattractive putative sons. When putative fathers were presented as stepfathers, the effect of the boy's attractiveness on the stepfather's attractiveness was lower and less consistent (Study 2). This suggests that the presence of an attractive boy has the strongest effect on the perceived attractiveness of putative fathers rather than on non-fathers. The generalized effect of priming with beautiful non-human objects also exists, but its effect is much weaker compared with the effects of putative biological sons (Study 3). Overall, this study highlighted the importance of post-mating sexual selection in humans and suggests that the heritable attractive traits of men are also evaluated by females after mating and/or may be used by females in mate poaching.

"There is such a thing as too many daughters, but not too many sons": A qualitative study of son preference and fetal sex selection among Indian immigrants in the United States.

Puri, Sunita; Adams, Vincanne; Ivey, Susan; Nachtigall, Robert D

2011-04-01

In response to concerns from feminists, demographers, bioethicists, journalists, and health care professionals, the Indian government passed legislation in 1994 and 2003 prohibiting the use of sex selection technology and sex-selective abortion. In contrast, South Asian families immigrating to the United States find themselves in an environment where reproductive choice is protected by law and technologies enabling sex selection are readily available. Yet there has been little research exploring immigrant Indian women's narratives about the pressure they face to have sons, the process of deciding to utilize sex selection technologies, and the physical and emotional health implications of both son preference and sex selection. We undertook semi-structured, in-depth interviews with 65 immigrant Indian women in the United States who had pursued fetal sex selection on the East and West coasts of the United States between September 2004 and December 2009. Women spoke of son preference and sex selection as separate though intimately related phenomena, and the major themes that arose during interviews included the sociocultural roots of son preference; women's early socialization around the importance of sons; the different forms of pressure to have sons that women experienced from female in-laws and husbands; the spectrum of verbal and physical abuse that women faced when they did not have male children and/or when they found out they were carrying a female fetus; and the ambivalence with which women regarded their own experience of reproductive "choice." We found that 40% of the women interviewed had terminated prior pregnancies with female fetuses and that 89% of women carrying female fetuses in their current pregnancy pursued an abortion. These narratives highlight the interaction between medical technology and the perpetuation of this specific form of violence against women in an immigrant context where women are both the assumed beneficiaries of reproductive choice

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

Science.gov (United States)

Akcinar, Berna; Shaw, Daniel S

2018-06-01

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.

Paternal antisocial behavior and sons' cognitive ability: a population-based quasiexperimental study.

Science.gov (United States)

Latvala, Antti; Kuja-Halkola, Ralf; Långström, Niklas; Lichtenstein, Paul

2015-01-01

Parents' antisocial behavior is associated with developmental risks for their offspring, but its effects on their children's cognitive ability are unknown. We used linked Swedish register data for a large sample of adolescent men (N = 1,177,173) and their parents to estimate associations between fathers' criminal-conviction status and sons' cognitive ability assessed at compulsory military conscription. Mechanisms behind the association were tested in children-of-siblings models across three types of sibling fathers with increasing genetic relatedness (half-siblings, full siblings, and monozygotic twins) and in quantitative genetic models. Sons whose fathers had a criminal conviction had lower cognitive ability than sons whose fathers had no conviction (any crime: Cohen's d = -0.28; violent crime: Cohen's d = -0.49). As models adjusted for more genetic factors, the association was gradually reduced and eventually eliminated. Nuclear-family environmental factors did not contribute to the association. Our results suggest that the association between men's antisocial behavior and their children's cognitive ability is not causal but is due mostly to underlying genetic factors. © The Author(s) 2014.

...And Kronos Ate His Sons

Science.gov (United States)

Vitiello, Giuseppe

In closed systems, energy is conserved. The origin of the time axis is completely arbitrary due to the invariance under continuous time-translations. The flowing of time swallows those fictitious origins one might assign on its axis, as Kronos ate his sons. Dissipation breaks such a scenario. It implies a non-forgettable origin of time. Open systems need their complement (their "double") in order to become, together, a closed system. Time emerges as an observable measured by the evolution of the open system complement, which acts as a clock. The conservation of the energy-momentum tensor in electrodynamics is considered and its relation with dissipative systems and self-similar fractal structures is discussed. The isomorphism with coherent states in quantum field theory (QFT) is established and the generator of transitions among unitarily inequivalent representations of the canonical commutation relations (CCR) is shown to provide sequences in time of phases, which defines the arrow of time. Merging properties of electrodynamics, fractal self-similarity, dissipation and coherent states point to an integrated vision of Nature.

Les Ilenti ou maudire son prochain en turc

Directory of Open Access Journals (Sweden)

Altan Gokalp

2009-05-01

Full Text Available La langue turque contemporaine dispopse d’un nombre important de formules d’invective et de malédiction qui relèvent d’un genre appelé ilenç ou ilenti, forme qui est connue depuis les premières inscriptions turques runiques de la Haute Asie. Bien que l’islam réprouve le fait de maudire son prochain, le genre issu d’une grande tradition turque ancienne est d’un usage commun chez les Turcs. Plus encore, la manière de maudire relève d’une tradition savante, d’un « Grand Parler » qui s’apparente aux genres littéraires les plus classiques comme l’épopée, le conte ou la poésie lyrique : la métrique, les rimes, l’usage des assonances obéissent aux mêmes règles que la grande tradition littéraire turque. En cela, le fait d’user de l’invective et de la malédiction est d’une certaine manière une prétention à la distinction et à la domination de l’autre. Les cibles de l’invective éclairent bien cette volonté de dominer et de détruire son ennemi (le corps, la famille, la maladie, une mort peu digne, etc..

'SON-GO-KU' : a dream of automated library

Science.gov (United States)

Sato, Mamoru; Kishimoto, Juji

In the process of automating libraries, the retrieval of books through the browsing of shelves is being overlooked. The telematic library is a document based DBMS which can deliver the content of books by simulating the browsing process. The retrieval actually simulates the process a person would use in selecting a book in a real library, where a visual presentation using a graphic display is substituted. The characteristics of prototype system "Son-Go-Ku" for such retrieval implemented in 1988 are mentioned.

The relation of son preference and religion to induced abortion: the case of South Korea.

Chung, Woojin

2007-09-01

This paper explores the factors that influence the practice of induced abortion in a very low fertility society, with particular emphasis on son preference and three distinct religions: Confucianism, Buddhism and Christianity. Using multivariate logistic regression models fitted by the generalized estimating equation (GEE) method, this paper analysed the data collected by the 2000 Korea National Fertility and Family Health Survey of 6348 married women aged 15-49 years with a total of 1217 pregnancy outcomes. The results showed that the likelihood of induced abortions in women with two or more children, compared with those with one child, was significantly influenced by the sex composition of the previous children: odds ratio (OR)=12.71 (95% CI=5.49, 29.42) for women with only son(s), and OR=3.91 (95% CI=1.67, 9.14) for women with only daughter(s). At parity two, women with two sons were much more likely to have induced abortions than women with two daughters (OR=5.88, 95% CI=2.70, 12.85). Although Buddhist women were not significantly different from Confucian women in induced abortion practice, Christian women were much less likely than Confucian women to have an induced abortion (OR=0.39, 95% CI=0.18, 0.88 for women with only sons and OR=0.44, 95% CI=0.24, 0.81 for women with two children). This suggests that even in this very low fertility society, son preference and religious affiliation are significant predictors of women's practice of induced abortion.

Mother-son discrepant reporting on parenting practices: The contribution of temperament and depression.

Science.gov (United States)

Shishido, Yuri; Latzman, Robert D

2017-06-01

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.

Skotko, Brian G; Levine, Susan P; Goldstein, Richard

2011-10-01

This study asks parents who have children with Down syndrome (DS) how they feel about their lives so that such information could be shared with expectant couples during prenatal counseling sessions. A valid and reliable survey instrument was mailed to 4,924 households on the mailing lists of six non-profit DS organizations. Of the 2,044 respondents, 99% reported that they love their son or daughter; 97% were proud of them; 79% felt their outlook on life was more positive because of them; 5% felt embarrassed by them; and 4% regretted having them. The parents report that 95% of their sons or daughters without DS have good relationships with their siblings with DS. The overwhelming majority of parents surveyed report that they are happy with their decision to have their child with DS and indicate that their sons and daughters are great sources of love and pride.

Values that Fathers Communicate to Sons about Sex, Sexuality, Relationships, and Marriage.

Coakley, Tanya M; Randolph, Schenita D; Shears, Jeffrey; Collins, Patrick

2017-01-01

African American males between ages 13 and 24 are disproportionately affected by unintended pregnancy and sexually transmitted infections (STIs) such as chlamydia, gonorrhea, syphilis, and HIV/AIDS; indeed, they account for 50% of HIV infections among all youth. Clear communication between parents and their youth about sex is associated with higher rates of sexual abstinence, condom use, and intent to delay initiation of sexual intercourse, which can prevent STIs and unintended pregnancy. However, barriers exist for parents to educate their youth about sexual health. The purpose of this article is to explore the values fathers communicate to their sons to prevent their risky sexual behaviors that lead to STIs, HIV, and adolescent parenthood. This was a qualitative study conducted from May and June 2015. African American fathers (N = 29) who had sons, ages 10 to 15 years, participated in five focus groups across metropolitan and rural North Carolina communities in barbershops. A qualitative content analysis revealed four themes regarding areas that fathers imparted their values onto their sons to protect them from sexual health risks: (a) sex, (b) sexuality, (c) relationships, and (d) marriage. The findings have implications for social work and public health practice.

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.

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

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.

In this age of data-driven science and high-throughput biology, computational thinking is becoming an increasingly important skill for tackling both new and long-standing biological questions. However, despite its obvious importance and conspicuous integration into many areas of biology, computer science is still viewed as an obscure field that has, thus far, permeated into only a few of the biology curricula across the nation. A national survey has shown that lack of computational literacy in environmental sciences is the norm rather than the exception [Valle & Berdanier (2012) Bulletin of the Ecological Society of America, 93, 373-389]. In this article, we seek to introduce a few important concepts in computer science with the aim of providing a context-specific introduction aimed at research biologists. Our goal was to help biologists understand some of the most important mainstream computational concepts to better appreciate bioinformatics methods and trade-offs that are not obvious to the uninitiated. © 2015 John Wiley & Sons Ltd.

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.

Like father, like son: the intergenerational cycle of adolescent fatherhood.

Sipsma, Heather; Biello, Katie Brooks; Cole-Lewis, Heather; Kershaw, Trace

2010-03-01

Strong evidence exists to support an intergenerational cycle of adolescent fatherhood, yet such a cycle has not been studied. We examined whether paternal adolescent fatherhood (i.e., father of study participant was age 19 years or younger when his first child was born) and other factors derived from the ecological systems theory predicted participant adolescent fatherhood. Data included 1496 young males who were interviewed annually from the National Longitudinal Survey of Youth 1997. Cox regression survival analysis was used to determine the effect of paternal adolescent fatherhood on participant adolescent fatherhood. Sons of adolescent fathers were 1.8 times more likely to become adolescent fathers than were sons of older fathers, after other risk factors were accounted for. Additionally, factors from each ecological domain-individual (delinquency), family (maternal education), peer (early adolescent dating), and environment (race/ethnicity, physical risk environment)-were independent predictors of adolescent fatherhood. These findings support the need for pregnancy prevention interventions specifically designed for young males who may be at high risk for continuing this cycle. Interventions that address multiple levels of risk will likely be most successful at reducing pregnancies among partners of young men.

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.

‘To refer, not to characterise’: A synchronic look at the Son-of-Man logia in the Sayings Gospel Q

2013-03-01

Full Text Available The article intends to address the Son-of-Man problem by applying Delbert Burkett’s ‘question of reference’ to those Son-of-Man logia that appear in the Sayings Gospel Q. A position is taken that recent philological approaches to the Son-of-Man problem have not been overly convincing, successful or helpful. Similarly, attempting to determine the authenticity of individual Son-of-Man sayings has not led to any form of scholarly consensus. In place of these approaches, a synchronic approach is defended and applied to the Son-of-Man sayings in Q, with interesting results.

2011-01-01

Employing economic and social globalization indicators, we empirically analyze whether globalization affects women’s rights in the economic and social dimensions. Using panel data from 150 countries over the 1981-2008 period, we find that social globalization positively affects both women’s economic and social rights, while the impact of economic globalization disappears when controlling for social globalization. Furthermore, we find that social globalization also reduces ‘son preference’ pro...

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

Directory of Open Access Journals (Sweden)

H.B. Grobler

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.

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.

Selecting sex: the effect of preferring sons.

Science.gov (United States)

Hesketh, Therese

2011-11-01

Son preference remains common in countries from East Asia through South Asia to the Middle East and North Africa. Where sex selective technology and abortion are readily available, such as in China, South Korea and India, this has led to a marked excess in male births. Worst excesses are seen in parts of rural China where there are 140 male births for every 100 female. This leads to large numbers of unmarriageable men. Concerns about the consequences centre around the propensity to aggression and violence of these men with increased levels of crime and antisocial behaviour, threatening societal stability and security. But recent studies do not support these assumptions, but rather suggest that these men are marginalised, lonely, withdrawn and prone to psychological problems. Measures to reduce sex selection should include enforcement of existing legislation on sex-selection, and public awareness campaigns about the dangers of late abortion and gender imbalance.

Why Are Indian Children So Short? The Role of Birth Order and Son Preference.

Science.gov (United States)

Jayachandran, Seema; Pandi, Rohini

2017-09-01

Child stunting in India exceeds that in poorer regions like sub-Saharan Africa. Data on over 168,000 children show that, relative to Africa, India's height disadvantage increases sharply with birth order. We posit that India’s steep birth order gradient is due to favoritism toward eldest sons, which affects parents' fertility decisions and resource allocation across children. We show that, within India, the gradient is steeper for high-son-preference regions and religions. The gradient also varies with sibling gender as predicted. A back-of-the-envelope calculation suggests that India's steeper birth order gradient can explain over one-half of the India-Africa gap in average child height.

Full Text Available La présente contribution se propose d’enquêter sur l’imprimeur-libraire Benoît Rigaud à la fois par le biais d’une étude de sa production globale et par une analyse portant sur ses impressions chevaleresques. Benoît Rigaud est l’un des éditeurs les plus prolifiques du XVIe siècle français, avec une activité qui s’étend sur plus que 40 ans et avec 1500 impressions environ. Entre 1572 et 1597, Rigaud publie de nombreux romans de chevalerie, à la fois médiévaux et renaissants, et devient l’un des imprimeurs les plus influents du marché chevaleresque de la fin du siècle. Après un préambule sur la réception des romans de chevalerie au XVIe siècle, la vaste production de Rigaud fait l’objet d’une analyse quantitative, avant que ne soit analysée la production des récits de chevalerie. Les données récoltées permettent de tirer des conclusions sur la dynamique éditoriale du genre chevaleresque ainsi que sur sa réception dans la seconde moitié du XVIe siècle.This research seeks to shed light on the publisher Benoît Rigaud both through a study of his global production and an analysis of his chivalry printed books. Benoît Rigaud is one of the most productive publishers of 16th century France, with an activity covering more than 40 years, years during which he printed around 1500 books. Moreover, between 1572 and 1597, Rigaud printed many chivalry romances, both medieval and modern texts, so that he became one of the main publishers of chivalry literature of that period. In this research, after some short remarks upon the reception of chivalry romances in 16th century, the large production of Rigaud is subject to a quantitative analysis. Then, his production of chivalry romances is studied more in detail. The collected data lead us to draw conclusions on the dynamic of the chivalry genre as well as on his reception in the second half of the 16th century.

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. Also the choice of a hybrid language contributes to create a highly connoted cultural context. In Bakunin’s Son, in fact, the Italian and the Sardinian overlap in a manner that cannot be distinguished or graphically marked, since form and meaning are fused together.Key words: dialogic novel, hybrid language.O filho de Bakunin, um romance polifónico de Sergio AtzeniO romance breve de Sergio Atzeni, O filho de Bakunin, è a perfeita exemplificação da teoria bachtininana do romance polifónico. O autor insere as histórias e as persona gens, geralmente abatidas, pessoas humildes e marginalizadas, na sua terra natal, a Sardenha. A história è estruturada na forma de entrevista a trinta e duas persona gens que com os seus pontos de vista criam una realidade multi-facetada e subjectiva. A vida de Tullio Saba, o protagonista, está narrada às vezes em modo contraditório e, por isso, os factos podem ser divergentes nas opiniões de quem esteve mais ou menos em contacto directo com ele. O uso característico de um instrumento linguístico híbrido, a meio caminho entre o italiano e o sardo, conota não somente o léxico mas também a estruturação inteira do discurso que atinge o efeito final pretendido pelo autor de descrever uma diversa ealidade antropológico-cultural.Palavras chave: romance polifónico, instrumento linguístico híbrido

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

Directory of Open Access Journals (Sweden)

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.

The corrected triple sum expression of Alisauskas (1987 J. Phys. A: Math. Gen. 20 35) for the recoupling (Racah) coefficients (6j-symbols) of the symmetric (most degenerate) representations of the orthogonal groups SO(n) (previously derived from the fourfold sum expression of Alisauskas also related to the result of Hormess and Junker (1999 J. Phys. A: Math. Gen. 32 4249) is rearranged into three new different double sum expressions (related to the hypergeometric Kampe de Feriet type series) and a new triple sum expression with preferable summation condition. The Regge type symmetry of special 6j-symbols of the orthogonal groups SO(n) in terms of special Kampe de Feriet F 1:4 1:3 series is revealed. The recoupling coefficients for antisymmetric representations of symplectic group Sp(2n) are derived using their relation with the recoupling coefficients of the formal orthogonal group SO(-2n)

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.

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.

Parents' perceptions of their adolescent sons' recovery in a therapeutic community for addicted clients.

Science.gov (United States)

Chen, Gila; Elisha, Ety; Timor, Uri; Ronel, Natti

2013-11-01

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.

The Quest for the Whole in D. H. Lawrence’s Sons and Lovers

2013-10-01

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.

Les commentaires de ces premiers critiques (souvent oubliés importent principalement parce qu’ils exprimaient nombre des inquiétudes (sinon toutes qui deviendraient plus tard centrales à la critique de la SF du xxe siècle : l’impact de la science et de la technologie sur les valeurs humaines, la logistique du voyage spatial, les frontières fluctuantes entre le réel et l’imaginaire, la description de l’« altérité » radicale, et les futurs possibles de notre monde. Bien plus, elles soulevaient invariablement des questions essentielles concernant les traits définitoires du genre lui-même dans sa forme en constante évolution : ses thèmes de prédilection, ses visées sociales, son didactisme scientifique et moral, son degré de vraisemblance constitutif, et sa place dans le canon littéraire occidental. Enfin, à l’aube du nouveau millénaire, il semble pertinent de regarder notre passé lointain pour redécouvrir ce que ces premiers commentateurs avaient à dire des nombreux ouvrages de science-fiction de leur époque : ceci sert à approfondir notre connaissance de la continuité historique du débat actuel sur la SF et à nous faire prendre conscience de la façon dont les choses ont à la fois beaucoup et peu changé à travers les siècles.

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

Directory of Open Access Journals (Sweden)

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.

BALTIMORE’S M.S. LEVY AND SONS: Straw Hat Makers to the World, 1870-1960

Full Text Available From 1860 to 1960, Baltimore was an important center of the men’s ready-to- wear clothing industries. German-speaking Jews created many businesses that manufactured and sold underwear, men’s suits, and specialty items like hats and umbrellas. The straw hat making firm started by M.S. 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.

To characterise the intratheoretical interests of knowledge in nursing science as an epistemological framework for fundamental care. For Jürgen Habermas, theory does not separate knowledge interests from life. All knowledge, understanding and human research is always interested. Habermas formulated the knowledge interests in empirical-analytical, historical-hermeneutic and critical social sciences; but said nothing about health sciences and nursing science. Discursive paper. The article is organised into five sections that develop our argument about the implications of the Habermasian intratheoretical interests in nursing science and fundamental care: the persistence of a technical interest, the predominance of a practical interest, the importance of an emancipatory interest, "being there" to understand individuals' experience and an "existential crisis" that uncovers the individual's subjectivity. The nursing discipline can take on practical and emancipatory interests (together with a technical interest) as its fundamental knowledge interests. Nurses' privileged position in the delivery of fundamental care gives them the opportunity to gain a deep understanding of the patient's experience and illness process through physical contact and empathic communication. In clinical, academic and research environments, nurses should highlight the importance of fundamental care, showcasing the value of practical and emancipatory knowledge. This process could help to improve nursing science's leadership, social visibility and idiosyncrasy. © 2017 John Wiley & Sons Ltd.

Transgenerational effects of nutrition are different for sons and daughters.

Zizzari, Z V; van Straalen, N M; Ellers, J

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.

Young Children’s Risk-Taking: Mothers’ Authoritarian Parenting Predicts Risk-Taking by Daughters but Not Sons

Directory of Open Access Journals (Sweden)

Erin E. Wood

2017-01-01

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.

The Son's Fault: Martin Luther King, Jr.'s Search for and Recovery of Sonship.

Science.gov (United States)

Hinds, Jay-Paul

2018-04-01

This article examines the role of sonship in the psychological and spiritual development of men. In using the methodology of psychobiography, I explore the life history of Martin Luther King, Jr. to analyze his search for and recovery of sonship. I propose that sonship helps men rebel against and, in the end, overcome the feelings of inadequacy that are experienced in their struggles to achieve manhood, particularly within the father-son dyad. The scholarship of pastoral theologian Donald Capps is instructive in this regard, in that he suggests that sons should be allowed to search for a male figure, a father-substitute, who can affirm, not disdain or reject, this state of sonship. In the end, what is often viewed as a negative act of regression-i.e., the recovery of and return to sonship-is recognized instead as a positive one that assists a man in his journey toward wholeness.

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 Objective: Revealing the experience of mothers when massaging their children to know the phenomenon in the context of a mother-child healthy development. Method: This is a qualitative study with a phenomenological approach carried out with 11 women who massaged their children and answered the guiding question: What did the experience of massaging your child mean to you? Results: The experience of massaging their children meant the development of their being a mother and of being a son/daughter, in addition to developing the attachment relationship between them. The massage can operationalize this integrality, become a tool of communication, stimulation and promotion of secure attachment, by promoting the loving interaction between mother and child. Conclusion: This practice should be considered as an option in the programs that promote the comprehensive health of the mother and child.

Compared study of the local structure of alteration products of SON 68 glass and natural gels; Etude comparee de la structure locale des produits d'alteration du verre SON 68 et de gels naturels

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)

Death of a son is associated with risk of suicide among parous women in Taiwan: a nested case-control study.

The impact of the sex of a deceased child on maternal suicide has not been studied. We examined whether the death of a child, especially a son, increased the risk of suicide among parous Taiwanese women. This matched case-control study was done within a cohort of 1 292 462 Taiwanese women who experienced a first and singleton childbirth between 1 January 1978 and 31 December 1987 and were followed up until 31 December 2008. From the cohort, 2701 suicide cases were identified and 2701 controls were randomly selected. Multiple logistic regression was used to estimate the risk of suicide associated with the death of a child. The adjusted odds ratios (ORs) for suicide among mothers whose son had died were 2.60 (95% CI = 1.18-5.73), 2.58 (1.28-5.20), and 4.20 (0.79-22.45) for death of a son aged younger than 1 year, 1 to 17 years, and 18 years or older. The ORs for suicide associated with the death of a daughter were not statistically significant: the respective adjusted ORs were 1.86 (0.82-4.62), 1.38 (0.54-3.49), and 2.48 (0.40-15.51). The death of a child, especially a son, increased the risk of maternal suicide, which supports the notion that preference for a son is firmly rooted in traditional Chinese culture.

DOLOR Y SUFRIMIENTO NO SON SINÓNIMOS PERO SON INTRÍNSECOS A LA NATURALEZA HUMANA:UNA VISIÓN DEL DOLOR Y EL SUFRIMIENTO HUMANO

Full Text Available El dolor y el sufrimiento no tienen un referente histórico en el hombre. Solo desde que el hombre es consciente de su humanidad se presenta el dolor y el sufrimiento. El hombre y el dolor siempre han existido, se sufre cuando se nace y se siente dolor, proceso que se repite en cada respiración celular, en cada reacción de oxireducción. Bioló-gicamente en Latín PATIOR = SUFRIR-PADECER es el esfuerzo energético de todo ser vivo para su integración factorial celular.En la medicina el dolor tiene su explicación anatómica y fisiológica, el dolor hace referencia a lo somático y a lo fisiológico. El Dolor agudo es la consecuencia inmediata de la activación del siste-ma nociceptivo, generalmente por un daño tisular somático o visceral, desapareciendo habitualmente con la lesión que lo originó. El Dolor crónico es aquel que persiste en ausencia de la lesión perifé-rica inicial. En la esencia de la filosofía el dolor es impensable e inteligible, se siente, se maneja se tolera pero no se piensa en dolor. Dolor y sufrimiento no son sinónimos pero son intrínsecos a la naturaleza humana. El hombre cuando experimenta el dolor se encuentra con su propio límite, con su propia impotencia de no poder cambiar un hecho real. El sufrimiento humano en la atención diaria del paciente enfermo no lo maneja-mos por ser este algo intangible no monitorizable y mucho menos medible y cuantificable.El dolor del enfermo no es libre ni voluntario, es producto de la fragilidad de su materia, el dolor del que sufre despierta en sus familiares la solidaridad y Tolerancia.

Using BiSON to detect solar internal g-modes

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.

Dombey and Son: An Inverted Maid's Tragedy

2015-06-01

Full Text Available Ross Dabney, J. Butt & K. Tillotson, and others think that Dickens revised the role of Edith in the original plan of Dombey and Son upon the advice of a friend. I tend to believe that Dickens's swerve from his course was prompted by two motives, his relish for grand scenes, and his endeavour to engage the reader's sympathies for a character who was a victim of a social practice which he was trying to condemn. Dickens's humanitarian attitude sought to redeem the sinner and condemn the sin. In engaging the reader's sympathies,  Dickens  had entrapped his own.  Both Edith and Alice are shown as victims of rapacious mothers who sell anything, or anybody for money. While Good Mrs Brown sells Alice's virtue and innocence for cash, Mrs Skewton trades on Edith's beauty in the marriage market to secure fortune and a good establishment. Edith and Alice's maturity and moral growth and their scorn and anger at their mothers' false teaching come in line with public prudery. Moreover, their educators in the principles of Mammonism have not succeeded altogether in stifling their innate feminine tenderness and capacity for affection, the thing that draws them near their reader's heart and wins them love and sympathy.

The generalized Trivers-Willard hypothesis (gTWH) proposes that parents who possess any heritable trait which increases male reproductive success at a greater rate than female reproductive success in a given environment will have a higher-than-expected offspring sex ratio, and parents who possess any heritable trait which increases the female reproductive success at a greater rate than male reproductive success in a given environment will have a lower-than-expected offspring sex ratio. One heritable trait which increases the reproductive success of sons much more than that of daughters is unrestricted sociosexual orientation. We therefore predict that parents with unrestricted sociosexual orientation (measured by the number of sexual partners, frequency of sex, and attitudes toward relationship commitment and sexual exclusivity) have a higher-than-expected offspring sex ratio (more sons). We analyse the US General Social Surveys and the National Longitudinal Study of Adolescent Health (Add Health), both with large nationally representative samples. Our analyses support the prediction from the gTWH. One standard deviation increase in unrestrictedness of sociosexual orientation increases the odds of having a son by 12-19% in the representative American samples.

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.

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 {sup 32}Si-doped SON68 also suggest that the movement of Si through the claystone is controlled by a chemically coupled transport with a Si retention factor, K{sub d}, of 900 mL/g.

Social defeat models in animal science: What we have learned from rodent models.

Science.gov (United States)

Toyoda, Atsushi

2017-07-01

Studies on stress and its impacts on animals are very important in many fields of science, including animal science, because various stresses influence animal production and animal welfare. In particular, the social stresses within animal groups have profound impact on animals, with the potential to induce abnormal behaviors and health problems. In humans, social stress induces several health problems, including psychiatric disorders. In animal stress models, social defeat models are well characterized and used in various research fields, particularly in studies concerning mental disorders. Recently, we have focused on behavior, nutrition and metabolism in rodent models of social defeat to elucidate how social stresses affect animals. In this review, recent significant progress in studies related to animal social defeat models are described. In the field of animal science, these stress models may contribute to advances in the development of functional foods and in the management of animal welfare. © 2017 The Authors.

A unique family survey was conducted in Nepal to investigate the economic consequences of having a first-born girl. Women get more children, but we find no causal effect of number of children on economic outcomes. But independently of the number of children there is a positive effect on boys' education of having a first born sister, who presumably takes care of household work so the boys can focus on school. This indicates a stronger son-preference in Nepal than what is found in studies from ...

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.

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

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.

We prospectively studied parental mental health after suddenly losing a son in a military training accident. Parents (N = 32) were interviewed at 1, 2 and 23 years after the death of their son. The General Health Questionnaire and Expanded Texas Inventory of Grief were self-reported at 1, 2, 5, and 23 years; the Inventory of Complicated Grief was self-reported at 23 years. We observed a high prevalence of psychiatric disorders at 1- and 2-year follow-ups (57% and 45%, respectively), particularly major depression (43% and 31%, respectively). Only one mental disorder was diagnosed at the 23-year follow-up. Grief and psychological distress were highest at 1- and 2-year follow-ups. Spouses exhibited a high concordance of psychological distress. Mothers reported more intense grief reactions than did fathers. The loss of a son during military service may have a substantial impact on parental mental health particularly during the first 2 years after death. Spouses' grief can be interrelated and may contribute to their psychological distress.

Wolfgang Pauli (1900-1958) is named by his colleagues in the same breath with Isaac Newton and Albert Einstein, who named Pauli his ''mental son''. The history of science had neglected Pauli for a long time. The reason for this may be found in Pauli's attempts to capture the role of the unconscious in physics and the meaning of dreams in the creation of scientific pictures of the world. For Pauli a scientific method consisted in activating the unconscious and hoping that it would start up that specific type of ''painting viewing'' from which the terms can arise by which we express our understanding

Polyandrous females provide sons with more competitive sperm: Support for the sexy-sperm hypothesis in the rattlebox moth (Utetheisa ornatrix).

Egan, Andrea L; Hook, Kristin A; Reeve, H Kern; Iyengar, Vikram K

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).

Periventricular nodular heterotopia is a common malformation of cortical development in which the migration of developing neurons destined for the cerebral cortex is abbreviated. Bilateral periventricular nodular heterotopia is most commonly an X-linked disorder that involves mutations in the filamin A (FLNA) gene, but an autosomal recessive form and sporadic forms have been identified. To our knowledge, autosomal dominant transmission of isolated periventricular nodular heterotopia has not been reported. Periventricular nodular heterotopia has a heterogeneous phenotype, associated commonly with seizure disorder, and more recently with reading deficits and visual-spatial deficits in some patients. We present a father and son with bilateral periventricular nodular heterotopia and similar visual-spatial learning deficits, consistent with nonverbal learning disability.

Thermodynamic and structural models compared with the initial dissolution rates of SON glass samples

International Nuclear Information System (INIS)

Tovena, I.; Advocat, T.; Ghaleb, D.; Vernaz, E.

1993-01-01

The experimentally determined initial dissolution rate R 0 of nuclear glass was correlated with thermodynamic parameters and structural parameters. The initial corrosion rates of six ''R7T7'' glass samples measured at 100 deg C in a Soxhlet device were correlated with the glass free hydration energy and the glass formation enthalpy. These correlations were then tested with a group of 26 SON glasses selected for their wide diversity of compositions. The thermodynamic models provided a satisfactory approximation of the initial dissolution rate determined under Soxhlet conditions for SON glass samples that include up to 15 wt% of boron and some alumina. Conversely, these models are inaccurate if the boron concentration exceeds 15 wt% and the glass contains no alumina. Possible correlations between R 0 and structural parameters, such as the boron coordination number and the number of nonbridging oxygen atoms, were also investigated. The authors show that R 0 varies inversely with the number of 4-coordinate boron atoms; conversely, the results do not substantiate published reports of a correlation between R 0 and the number of nonbridging oxygen atoms.

Sundell, J

2017-07-01

The scientific articles and Indoor Air conference publications of the indoor air sciences (IAS) during the last 50 years are summarized. In total 7524 presentations, from 79 countries, have been made at Indoor Air conferences held between 1978 (49 presentations) and 2014 (1049 presentations). In the Web of Science, 26 992 articles on indoor air research (with the word "indoor" as a search term) have been found (as of 1 Jan 2016) of which 70% were published during the last 10 years. The modern scientific history started in the 1970s with a question: "did indoor air pose a threat to health as did outdoor air?" Soon it was recognized that indoor air is more important, from a health point of view, than outdoor air. Topics of concern were first radon, environmental tobacco smoke, and lung cancer, followed by volatile organic compounds, formaldehyde and sick building syndrome, house dust-mites, asthma and allergies, Legionnaires disease, and other airborne infections. Later emerged dampness/mold-associated allergies and today's concern with "modern exposures-modern diseases." Ventilation, thermal comfort, indoor air chemistry, semi-volatile organic compounds, building simulation by computational fluid dynamics, and fine particulate matter are common topics today. From their beginning in Denmark and Sweden, then in the USA, the indoor air sciences now show increasing activity in East and Southeast Asia. © 2017 John Wiley & Sons A/S.

Mothers’ Academic Gender Stereotypes and Education-Related Beliefs About Sons and Daughters in African American Families

Science.gov (United States)

Wood, Dana; Kurtz-Costes, Beth; Okeke-Adeyanju, Ndidi; Rowley, Stephanie J.

2010-01-01

The role of African American mothers’ academic gender stereotype endorsement in shaping achievement-related expectations for and perceptions of their own children was examined. Mothers (N = 334) of 7th and 8th graders completed measures of expectations for their children’s future educational attainment, perceptions of their children’s academic competence, and academic gender stereotypes. Consistent with hypotheses, mothers held less favorable expectations for sons and perceived sons to be less academically competent than daughters. In addition, mothers reported stereotypes favoring girls over boys in academic domains; stereotype endorsement, in turn, was related to mothers’ educational expectations for and beliefs about the academic competence of their own children, even with youths’ actual achievement controlled. Negative stereotypes about the academic abilities of African American boys may create a negative feedback loop, thereby contributing to the maintenance of the gender gap in African Americans’ educational outcomes.

Poesía y filosofía son de palabra

Santamaría Pargada, Antonio

2006-04-01

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.

Terrorism in Pakistan: a behavioral sciences perspective.

Nizami, Asad Tamizuddin; Rana, Mowadat Hussain; Hassan, Tariq Mahmood; Minhas, Fareed Aslam

This article reviews the behavioral science perspectives of terrorism in Pakistan. It can be argued that Pakistan has gained worldwide attention for "terrorism" and its role in the "war against terrorism". The region is well placed geopolitically for economic successes but has been plagued by terrorism in various shapes and forms. A behavioral sciences perspective of terrorism is an attempt to explain it in this part of the world as a complex interplay of historical, geopolitical, anthropological and psychosocial factors and forces. Drawing from theories by Western scholars to explain the behavioral and cognitive underpinnings of a terrorist mind, the authors highlight the peculiarities of similar operatives at individual and group levels. Thorny issues related to the ethical and human right dimensions of the topic are visited from the unique perspective of a society challenged by schisms and divergence of opinions at individual, family, and community levels. The authors have attempted to minimize the political descriptions, although this cannot be avoided entirely, because of the nature of terrorism. Copyright © 2014 John Wiley & Sons, Ltd.

The prodigal son: some psychological aspects of Augustine's conversion to Christianity.

Science.gov (United States)

Nauta, Rein

2008-03-01

Augustine's conversion is considered exemplary for its Christian testimony. However, the psychological aspects are also relevant, for Augustine's conversion to Christianity was as much inspired by personal and cultural ambitions as by religious convictions. For Augustine, the conversion to the Christian faith spelled a life of asceticism--a life of celibacy, a virtuous and chaste existence, which also offered him a means of escape from the threatening ambiguity of parental relations and a chance to realize the cultural ideal of the civilized philosopher who has subjugated the passions of the flesh. In this paper we explore the psychological dynamics of the absent father, the suffering mother and the prodigal son and the role they played in Augustine's conversion to Christianity.

Latinos suffer a disproportionate burden of human papillomavirus (HPV)-preventable cancers, yet uptake and completion of the HPV vaccine among Latinos is below recommendations. Reasons for low HPV vaccine uptake among Latinos in Utah are unknown. We surveyed Latino parents of HPV vaccine age-eligible adolescents (N=118). Univariable analyses identified sociodemographic characteristics associated with HPV vaccine awareness, interest, and uptake for daughter(s) and/or son(s) using chi-square tests or Fisher's exact tests. More parents who had lived in the USA for 15 years or more had vaccinated their daughter (43.6 vs. 32.5%, p=0.035) compared to those living in the USA for shorter time periods. Parents born in Mexico reported their son had not received the HPV vaccine (74.6 vs. 58.3%, p=0.049) more than those born elsewhere. Parents with Mexican birthplace and ancestry reported not knowing about the HPV vaccine as the main barrier to vaccinating daughters (47.1 vs. 5.9%, p=0.002 for both) and sons (birthplace 38.3 vs. 10.3%, p=0.007; ancestry 37.1 vs. 11.1%, p=0.013) compared to those born or descending elsewhere. Non-acculturated parents with a son were more likely to report not knowing about the HPV vaccine as the main barrier to vaccine receipt (47.6 vs. 12.5%, pLatinos in an understudied region and complement prior research in other regions. This study may have implications for designing culturally tailored interventions to improve uptake of the HPV vaccine among the growing population of Latinos in Utah, and other states in the Intermountain West.

Ahmad, N.

1997-01-01

Sir J. J. Thomson was the first to discover a subatomic particle i. e. electron. Due to this discovery he is remembered in the history as T he Atom Smasher . He was a great experimentalists and a devoted physicist. He himself, his son and his seven pupils earned Noble prizes on the basis of their scientific discoveries. The discovery of electron by Sir Thomson in 1897, at Cavendish Laboratory, has rewritten the entire physical science. Although electron has wide spread applications in almost every field, yet its exact nature is not fully known. This article briefly describes the life of Sir Thomson, his achievements and the impact of his discovery of electron on the twentieth century science and technology. (author)

A case study of conflict management in bonobos: how does a bonobo (Pan paniscus) mother manage conflicts between her sons and her female coalition partner?

Science.gov (United States)

Legrain, L; Stevens, J; Alegria Iscoa, J; Destrebecqz, A

2011-01-01

Female coalitions are an important part of the social organization of bonobos. The strength of the mother-son relationship is another essential part of this social structure. A bonobo mother is therefore facing a dilemma when a conflict arises between her sons and her female coalition partners. Will she take her coalition partner's side and favour the social organization of the group or support her son in order to defend her offspring? In order to address this issue, we performed an observational study of the captive group at Planckendael (Belgium) and used social grooming and proximity to assess the relationship between individuals. As a case study, we focused on the relationships between Hortense, one of the group's mothers, her 3 sons Redi, Vifijo and Zamba, and her coalition partner Hermien. Surprisingly, we observed that Hortense preferentially supported her female coalition partner. For Hortense's social status in the group, it may be more important to maintain the strong relationship with her higher-ranking female coalition partner than to support her sons. Copyright © 2012 S.

Superselection sectors of SO(N) Wess-Zumino-Witten models

International Nuclear Information System (INIS)

Boeckenhauer, J.

1996-06-01

The superselection structure of so(N) WZW models is investigated form the point of view of algebraic quantum field theory. At level 1 it turns out that the observable algebras of the WZW theory can be constructed in terms of even CAR algebras. This fact allows to give a formulation of these models close to the DHR framework. Localized endomorphisms are constructed explicitly in terms of Bogoliubov transformations, and the WZW fusion rules are proven using the DHR sector product. At level 2 it is shown that most of the sectors are realized in H NS =H NS x H NS where H NS is the Neveu-Schwarz sector of the level 1 theory. The level 2 charcters are derived and H NS is decomposed completely into tensor products of the sectors of the WZW chiral algebra and irreducible representation spaces of the coset Virasoro algebra. Crucial for this analysis is the DHR decomposition of H NS into sectors of a gauge invariant fermion algebra since the WZW chiral algebra as well as the coset Virasoro algebra are invariant under the gauge group O(2).

Intergenerational Transfers of Preferences for Science Careers in Comparative Perspective

Science.gov (United States)

Sikora, Joanna; Pokropek, Artur

2012-11-01

Using data from 24 countries, which participated in the 2006 Programme for International Student Assessment (PISA), we examine the relationship between parental science employment and students' career expectations. In contrast to prior PISA-based studies, we find that the link between parental employment and adolescent plans to work in science is non-trivial and merits attention. In this context, we consider three versions of the gender socialisation hypothesis. The strong variant posits that girls' plans are shaped solely by their mothers' career pathways while boys model their expectations exclusively on fathers' occupations. The weaker version of this hypothesis expects children to be influenced more by the same-sex than by the opposite-sex parent. Finally, the third possibility is that, as egalitarian ideologies prevail, parents inspire adolescent occupational plans regardless of gender. These hypotheses are assessed separately for student career plans related to biology, agriculture and health (BAH) in contrast to computing, engineering and mathematics (CEM), because the involvement in these fields of science is known to be segregated by gender. Using two-level multinomial logit modelling, we find some support for the weak version of the gender socialisation hypothesis. Although within-family transfers of preferences for science careers vary considerably across countries, we note certain regularities. In many nations, relevant paternal employment enhances sons' interest in science careers regardless of their field. In contrast, maternal employment inspires daughters in fewer countries and this influence tends to be limited to careers in BAH. We discuss the possible implications of these findings for science educators.

Malgré des similitudes superficielles avec la fiction moderne naturaliste (ou autre, les personnages de science-fiction sont toujours des personnes collectives, jamais individuelles. Je suggère que la critique littéraire contemporaine n’est pas l’outil idéal pour traiter de fiction didactique, ou pour évaluer une littérature nouvelle et différente.

Mais son recueil Rapture, publié en 2005, s’écarte radicalement du modèle féministe pour tenter une appropriation plus discrète de la tradition pétrarquisante de la poésie amoureuse. Resémiotisant les clichés, jouant sur une simplicité incantatoire, Duffy pratique ici l’écho plutôt que la réécriture, dans un dépouillement sensuel, explorant amour puis désamour au rythme d’une poésie qui emprunte au jazz ses variations fluides ou syncopées.

Parents' experience of living with and caring for an adult son or daughter with schizophrenia at home in Ireland: a qualitative study.

McAuliffe, R; O'Connor, L; Meagher, D

2014-03-01

This study explored the experience of parents living with, and caring for, an adult son or daughter with schizophrenia. There is increasing emphasis on the involvement of carers and users in the care for people with schizophrenia. 'A Vision for Change' highlights the need for a partnership approach and emphasizes that carers are an integral part in the planning and delivery of mental health services. In order to meet such requests, it was necessary to explore the meaning of caregiving for Irish families. A descriptive qualitative design was used to enable parents to describe their experiences. Semi-structured, in-depth interviews with a convenience sample of six parents in Ireland were carried out in 2007. The study encompassed four major themes: psychological tsunami, caring activities, coping with enduring illness and an uncertain pathway. Parents reported severe psychological distress when their son or daughter was diagnosed with schizophrenia. Their deep sense of loss was followed by acceptance of the situation. Feelings of love and a sense of responsibility helped to give meaning to their caring role. This study gave a voice to some parents of a son or daughter with schizophrenia. A family-centred approach should be at the core of care planning for this vulnerable population. © 2013 John Wiley & Sons Ltd.

Carl Wilhelm Naundorff was buried in 1845 in Delft as Louis Charles, Duc de Normandie, 'Louis XVII'. However, the son of Louis XVI and Marie-Antoinette-Louis XVII--officially died in the Temple of Paris in 1795. In order to resolve the identity of Naundorff, mitochondrial DNA (mtDNA) D-loop sequences of his remains were compared with the sequences obtained from the hairs of two sisters of Marie-Antoinette, Marie-Antoinette herself, and with the sequences obtained from DNA samples of two living maternal relatives. The mtDNA sequence of a bone sample from Naundorff showed two nucleotide differences from the sequences of the three sisters and four differences from the sequences of living maternal relatives. Based on this evidence it becomes very unlikely that Naundroff is the son of Marie-Antoinette.

Acceptability of the human papillomavirus vaccine and reasons for non-vaccination among parents of adolescent sons.

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.

Meaning Reconstruction Process After Suicide: Life-Story of a Japanese Woman Who Lost Her Son to Suicide.

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.

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

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.

Full Text Available La place très modeste des universités du Vietnam dans les classements mondiaux traduit le sous-développement scientifique de ce pays. Particulièrement en sciences de l’éducation, la situation est très décevante: de 1996 à 2010, seulement 39 articles sont publiés dans les revues internationales, mais on a formé des centaines de titulaires de master et de doctorat. Se pose donc la question de la qualité de la formation des jeunes chercheurs.

The anisotropy of the expansion coefficients of uranium, zirconium and zinc provoke internal tensions in the course of cooling these metals. These tensions are eliminated in the case of zinc by restoration to room temperature, but persist in uranium and zirconium and are responsible for the absence of an elastic limit in these two metals.

It was found that, for solids and more particularly for metals, in huge fields of shock pressure, the wave velocity is a linear function of the material velocity. A theoretical calculation allows to demonstrate this linear law and to calculate its parameters which are compared to experimental data.

Percec Dana

2014-03-01

Full Text Available The paper looks at Shakespeare’s historical play Richard III and its fairy tale-like character given by the configuration of the main character as an arch-villain and the presence of motifs and patterns typically associated with the fairy tale genre. More specifically, it considers the mother-son relationship between the Duchess of York and Richard in the light of the motif of monstrous birth. It is not a coincidence that the emergence of such motifs coincides with the historical contexts of the early modern period. Reading Richard III in this key is related to the revisionist approach to chronicle plays.

Despite the emergence of and widespread uptake of a growing range of medical and scientific professions in elite sport, such environs present a volatile professional domain characterized by change and unprecedentedly high turnover of personnel. This study explored sport medicine and science practitioners' experiences of organizational change using a longitudinal design over a 2-year period. Specifically, data were collected in three temporally defined phases via 49 semi-structured interviews with 20 sport medics and scientists employed by three organizations competing in the top tiers of English football and cricket. The findings indicated that change occurred over four distinct stages; anticipation and uncertainty, upheaval and realization, integration and experimentation, normalization and learning. Moreover, these data highlight salient emotional, behavioral, and attitudinal experiences of medics and scientists, the existence of poor employment practices, and direct and indirect implications for on-field performance following organizational change. The findings are discussed in line with advances to extant change theory and applied implications for prospective sport medics and scientists, sport organizations, and professional bodies responsible for the training and development of neophyte practitioners. © 2014 John Wiley & Sons A/S.

A new family of N dimensional superintegrable double singular oscillators and quadratic algebra Q(3) ⨁ so(n) ⨁ so(N-n)

Science.gov (United States)

Fazlul Hoque, Md; Marquette, Ian; Zhang, Yao-Zhong

2015-11-01

We introduce a new family of N dimensional quantum superintegrable models consisting of double singular oscillators of type (n, N-n). The special cases (2,2) and (4,4) have previously been identified as the duals of 3- and 5-dimensional deformed Kepler-Coulomb systems with u(1) and su(2) monopoles, respectively. The models are multiseparable and their wave functions are obtained in (n, N-n) double-hyperspherical coordinates. We obtain the integrals of motion and construct the finitely generated polynomial algebra that is the direct sum of a quadratic algebra Q(3) involving three generators, so(n), so(N-n) (i.e. Q(3) ⨁ so(n) ⨁ so(N-n)). The structure constants of the quadratic algebra itself involve the Casimir operators of the two Lie algebras so(n) and so(N-n). Moreover, we obtain the finite dimensional unitary representations (unirreps) of the quadratic algebra and present an algebraic derivation of the degenerate energy spectrum of the superintegrable model.

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.

Evolution of the uranium local environment during alteration of SON68 glass

International Nuclear Information System (INIS)

Jollivet, Patrick; Auwer, Christophe Den; Simoni, Eric

2002-01-01

The speciation of uranium in SON68 glass specimens doped with 0.75-3.5 wt% uranium and in the gels formed by alteration of the specimens was investigated by X-ray absorption spectroscopy. In the glasses, uranium is present at oxidation state VI and coordination number 6 with the same average distances than those found in a UO 3 type environment. The U-O distances and uranium coordination numbers are identical throughout the uranium concentration range. During glass alteration the uranium remains at oxidation state VI in the gels, but was found in the uranyl form. An increase in the equatorial distances (from 2.20 and 2.32 A in the glass to respectively 2.22 and 2.39 A in the gel) and coordination numbers (to about 7 and 8, respectively) was observed

The global tantalum industry and Sons of Gwalia Ltd

International Nuclear Information System (INIS)

Paull, D.

2002-01-01

Sons of Gwalia Ltd., in Perth Australia is a long-term supplier of tantalum (Ta), a valuable rare metal with adequate supply. Tantalum is soft and ductile with high melting and boiling points and a low co-efficient of thermal expansion. It has excellent capacity to store and release electrical charge and offers exceptional resistance to corrosion. Its' main use is in consumer electronics such as mobile phones, laptop computers, DVD players, personal video recorders and MP-3 players. For automotive electronics, tantalum is used for air-bags, audio systems, navigation systems, anti-lock break systems and under the hood vehicle management systems. The super alloy is also in demand by the aerospace industry and for turbine blades for power stations. The total demand of Tantalum in 2000 was 5 million lbs. Demand growth has increased steadily since 1993 with perhaps a slight increase in the past 5 years. Resources are estimated at a 125 year supply based on year 2000 production rates. 41 per cent of the world supply of tantalum is obtained from Australia, 13 per cent from Africa, 16 per cent from America, 22 per cent from Asia. The Greenbushes mine in Australia is the world's largest tantalum mine with 80 million lbs Ta, followed by Australia's Wodgina Mine with 50 million lbs Ta. Both mines are expected to be operational for the next 25 years. 12 figs

We extend the physics case for a new high-energy, ultra-high statistics neutrino scattering experiment, NuSOnG (Neutrino Scattering On Glass) to address a variety of issues including precision QCD measurements, extraction of structure functions, and the derived Parton Distribution Functions (PDFs). 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

Se consideran dos tipos de MOOC: unos los organizados por Siemens y Downes (cMOOC y otros los desarrollados en lugares como Stanford, con muchos estudiantes y loables objetivos (xMOOC; estos tienen también sus debilidades. Aunque han sido recibidos con altas expectativas, también han encontrado una fuerte oposición que está aumentando con el tiempo, lo que nos permite estudiar este fenómeno en profundidad. Aunque todavía hay pocas investigaciones empíricas sobre los efectos de los MOOC en el aprendizaje, este estudio trata de arrojar luz sobre el tema desde un punto de vista teórico. En primer lugar exploraremos las expectativas positivas y negativas generadas. Los MOOC pueden constituir una buena propuesta a gran escala, lo que solo es posible para unas pocas grandes instituciones. No hay estudio de mercado, ni modelo de negocio, ni investigaciones empíricas que permitan confirmar los anuncios de sus efectos positivos.

Full Text Available Bien que l’esthétique conversationnelle subisse une profonde remise en cause dans la création littéraire du XXe siècle, son héritage est encore perceptible dans le cadre d’un genre inventé grâce au développement de la médiatisation, l’entretien littéraire. L’émission télévisée « Duras-Godard », diffusée en 1987, donne à comprendre comment la mémoire des salons mondains hante encore la réception par le public moderne. Mais elle montre aussi l’art de Marguerite Duras pour faire siennes les normes de cette pratique sociale et en tirer des effets esthétiques propres à enrichir son œuvre publiée. Although the French aesthetic in the art of conversation has been called into question in 20th century literary creation, its heritage is still perceptible within the context of a genre invented by the expansion of mediatization: the literary interview. The television programme “Duras-Godard”, broadcast in 1987, reveals how the memory of social and literary salons still haunts the reception by a modern public. But it also shows how Marguerite Duras manages to appropriate the rules of this social practice to produce specific aesthetic effects in her published work.

In the Citizen Panel's Report on 'Electricity and Society' we present the first results of three intensive week-ends. In this document, 27 Swiss citizens have recorded their opinions on the future of our electricity supply system. Solutions are sought without making claims on having found the ultimate recipe. The recommendations are the result of an assessment made by a representative cross-section of the public - one could almost say 'the voice of the people'. They reflect not only the public's apprehensions and worries, but also their ideas and desires. (authors)

Exploring the consequences of combining medical students with and without a background in biomedical sciences.

Medical schools have tended to admit students with strong backgrounds in the biomedical sciences. Previous studies have shown that those with backgrounds in the social sciences can be as successful in medical school as those with science backgrounds. However, the experience of being a 'non-science' student over time has not been well described. A mixed-methods study was developed and run with the aim of elucidating the personal experiences of science and non-science students at our institution. Data were generated from a student survey that focused on participants' self-identification as science or non-science students, and on their sense of preparedness and stress, and from a series of student focus groups exploring participants' experiences of science and non-science issues in all aspects of their training. Descriptive statistics were generated for structured survey data. Focus group data and unstructured survey data were analysed to identify common themes. End-of-module and end-of-year examination data for the four class cohorts in the programme were also analysed to compare science and non-science student performance over time. There were clear differences between the experiences and performance of science and non-science students. We found dichotomies in students' self-reported sense of preparedness and stress levels, and marked differences in their examination performance, which diminished over time to converge around the third year of their studies. Combining science and non-science students in the same class affected the students to different extents and in different ways. The potential disruption of mixing science and non-science students diminished as their levels of performance converged. The psychosocial stress experienced by non-science students and the challenges it posed, in both their academic and their personal lives, have implications for how such students should be supported, and how curricula can be configured to afford quality learning for all

Mothers use linking object to externalize the complex aspects of their relationship to the loss of their child. We analyzed the linking objects that mothers kept in memory of their sons who disappeared in the 1991-1995 war in Croatia or whose remains were uncovered and identified long time after they had gone missing. The case study of disturbed mourning included 26 mothers of Croatian soldiers from Croatian Osijek-Baranja County who went missing in war or whose remains were recovered and identified long after they had gone missing. The mothers were selected independently by the president of the Association of Families of Missing and Detained Croatian Soldiers and agreed to participate in the study in 2001. They were interviewed in their homes, their testimonies were recorded, and photographs of the linking objects taken. Linking objects were classified according to the Volkan's four-group classification. Out of four Volkan's groups of linking objects, we identified the objects belonging to the first three. Those were 1) objects that had been worn by the deceased (clothes, wrist-watch, ring, or glasses), (6/26); 2) objects that could be viewed in the psychoanalytic sense as an extension of the body of the disappeared or dead person, such as a camera (4/26); and 3) objects with realistic or symbolic resemblance to the deceased, usually a photograph (8/26). None of the examined objects belonged to the fourth Volkan's group (objects at hand when the news of the death came or objects present at the funeral, things that could be considered last-minute objects, ie, related to the moment when the deceased was last seen alive). However, 8/26 objects formed a new hitherto undescribed group. Mothers used such objects to create a memorial shrine to their sons. A photograph of the missing person or person whose remains were identified long after he had gone missing occupied a central place at the shrine, and was surrounded by other symbols of the Catholic iconography (Virgin

Bad Boys Meet the Swan of Avon: A Re-Visioning of Hamlet in Sons of Anarchy

Directory of Open Access Journals (Sweden)

Burzyńska Katarzyna

2017-12-01

Full Text Available This article investigates the intersections between Shakespeare’s Hamlet and a popular TV series Sons of Anarchy (SOA, loosely based on the Shakespearean original. The crime drama series revolves around an outlaw motorcycle club that literally “rules” a fictional town in California like an old royal family with its own brutal dynastic power squabbles and dark family secrets. The club is governed by an unscrupulous President Clay and an equally violent, though more conflicted, Vice President Jax Teller, the son of the late President, who had died in mysterious circumstances. In the article I argue that the popularity of the series lies not in its graphic scenes of violence, over-the-top Harley chases, and sex intrigues, but rather in its Shakespearean and Renaissance structure. SOA, dubbed as “Hamlet on Harleys”1, is an appropriation rather than an adaptation of Shakespeare’s tragedy, which makes it a truly transmedial phenomenon. The article investigates a fascinating blend of seemingly marginal elements of modern American culture and the canonical British tragedy. It also addresses the connections between the lifestyles of the so called outlaw MC clubs and the early modern family structure as presented in Hamlet, focusing on the issues of power and gender relations.

In 2015, the Academy for Eating Disorders collaborated with international patient, advocacy, and parent organizations to craft the 'Nine Truths About Eating Disorders'. This document has been translated into over 30 languages and has been distributed globally to replace outdated and erroneous stereotypes about eating disorders with factual information. In this paper, we review the state of the science supporting the 'Nine Truths'. The literature supporting each of the 'Nine Truths' was reviewed, summarized and richly annotated. Most of the 'Nine Truths' arise from well-established foundations in the scientific literature. Additional evidence is required to further substantiate some of the assertions in the document. Future investigations are needed in all areas to deepen our understanding of eating disorders, their causes and their treatments. The 'Nine Truths About Eating Disorders' is a guiding document to accelerate global dissemination of accurate and evidence-informed information about eating disorders.

'Transfer' is the application of a previously learned concept to solve a new problem in another context. Transfer is essential for basic science education because, to be valuable, basic science knowledge must be transferred to clinical problem solving. Therefore, better understanding of interventions that enhance the transfer of basic science knowledge to clinical reasoning is essential. This review systematically identifies interventions described in the health professions education (HPE) literature that document the transfer of basic science knowledge to clinical reasoning, and considers teaching and assessment strategies. A systematic search of the literature was conducted. Articles related to basic science teaching at the undergraduate level in HPE were analysed using a 'transfer out'/'transfer in' conceptual framework. 'Transfer out' refers to the application of knowledge developed in one learning situation to the solving of a new problem. 'Transfer in' refers to the use of previously acquired knowledge to learn from new problems or learning situations. Of 9803 articles initially identified, 627 studies were retrieved for full text evaluation; 15 were included in the literature review. A total of 93% explored 'transfer out' to clinical reasoning and 7% (one article) explored 'transfer in'. Measures of 'transfer out' fostered by basic science knowledge included diagnostic accuracy over time and in new clinical cases. Basic science knowledge supported learning - 'transfer in' - of new related content and ultimately the 'transfer out' to diagnostic reasoning. Successful teaching strategies included the making of connections between basic and clinical sciences, the use of commonsense analogies, and the study of multiple clinical problems in multiple contexts. Performance on recall tests did not reflect the transfer of basic science knowledge to clinical reasoning. Transfer of basic science knowledge to clinical reasoning is an essential component of HPE that

The role of pH in the vapor hydration at 175 °C of the French SON68 glass

The French simulated nuclear waste SON68 glass was altered in the presence of water vapor at 175 °C and 98% of relative humidity under several atmospheres (NH_3, H_2S, CO_2 and argon). The objectives were to study the role of pH on hydration kinetics and secondary phases formation. The hydration was followed by infrared spectroscopy and the nature and extent of alteration products were determined by characterizing the reacted glass surface with scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), μ-Raman spectroscopy and X-ray diffraction (XRD). The glass hydration/alteration rate clearly increased with increasing pH, that is controlled by the gas atmosphere, as the following: NH_3 > Ar > CO_2 > H_2S. This can directly be linked to the secondary phases precipitated on the glass surface. Hence, the major alteration products observed at high pH (under NH_3 and Ar) are analcime and Ca-silicates hydrates (CSH) while at low pH (under CO_2 and H_2S) only a hydrated gel layer was identified. - Highlights: • The vapor hydration study of the SON68 glass under geological conditions. • The secondary phases formation in the alteration of SON68 glass. • The pH effect on the alteration kinetics of glass.

Seismic Interpretation of the Nam Con Son Basin and its Implication for the Tectonic Evolution

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.

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

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

Sexual imprinting on continuous variation: do female zebra finches prefer or avoid unfamiliar sons of their foster parents?

Science.gov (United States)

Schielzeth, H; Burger, C; Bolund, E; Forstmeier, W

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.

Son preference among the historical Sandžak Muslim population

Čvorović Jelena

2012-01-01

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

The association between an abusive father-son relationship, quantity of alcohol consumption, and male-to-male alcohol-related aggression.

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.

Bad Mothers and Monstrous Sons: Autistic Adults, Lifelong Dependency, and Sensationalized Narratives of Care.

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.

Breaking Gender Stereotypes: Encouraging more Women to Study Science, Technology and Mathematics

International Nuclear Information System (INIS)

Ramos, G.

2015-01-01

Why aren’t there more women working in the Nuclear field? OECD data can reveal some of the answers: when students are asked about the kind of career they expect to pursue as young adults even those girls who envision pursuing scientific careers expect to work in fields that are different from boys. Girls are over-represented among students who expect to work in the health and social fields; boys are over-represented among 15-year olds who expect to work as engineers or computer scientists, despite the fact that girls and boys show similar performance in science at school. Parents are also much more likely to expect their sons rather than their daughters to pursue these careers, even when their performance in mathematics is equally good. This has direct consequences: 14% of young women who entered university for the first time in 2012 chose science related fields, including engineering, manufacturing and construction. By contrast, 39% of young men who entered university that year chose to pursue one of those fields of study. These findings have serious implications not only for higher education, where young women are already under-represented in the science, technology, engineering and mathematics fields of study, but also later on, when these young women enter the labour market.

Rationalizing 'folk medicine' in interwar Germany: faith, business, and science at "Dr. Madaus & Co.'.

Science.gov (United States)

Timmermann, C

2001-12-01

The relationship between orthodox or mainstream medicine and heterodox or alternative practices has often been expressed in terms of dichotomies, such as science versus anti-science or rationality versus irrationality. By studying the history of a company producing herbal medicines and homoepathic remedies in Germany in the 1920s and 1930s, this paper attempts to create a more differentiated picture. 'Dr. Madaus & Co.' was founded in 1919 by the three sons of a free church minister and his wife, who practised as a non-licensed healer herself. The company not only sold medicines, it also produced journals and books promoting heterodox healing methods and contributing to ongoing health political debates, for example over compulsory vaccination programmes, human experimentation, quackery, and a general 'crisis of medicine'. Gerhard Madaus, a medical doctor and one of the three founders, published in 1938 a three-volume Textbook of Biological Healing Methods, turning folk medicine into science. The essay follows the rise of the Madaus family firm and interprets the story of 'Dr. Madaus & Co.' as an example of social rationalization, emphasizing the role of commercial operations in twentieth-century alternative medicine in Germany.

Achieving Conservation Science that Bridges the Knowledge–Action Boundary

Science.gov (United States)

Cook, Carly N; Mascia, Michael B; Schwartz, Mark W; Possingham, Hugh P; Fuller, Richard A

2013-01-01

There are many barriers to using science to inform conservation policy and practice. Conservation scientists wishing to produce management-relevant science must balance this goal with the imperative of demonstrating novelty and rigor in their science. Decision makers seeking to make evidence-based decisions must balance a desire for knowledge with the need to act despite uncertainty. Generating science that will effectively inform management decisions requires that the production of information (the components of knowledge) be salient (relevant and timely), credible (authoritative, believable, and trusted), and legitimate (developed via a process that considers the values and perspectives of all relevant actors) in the eyes of both researchers and decision makers. We perceive 3 key challenges for those hoping to generate conservation science that achieves all 3 of these information characteristics. First, scientific and management audiences can have contrasting perceptions about the salience of research. Second, the pursuit of scientific credibility can come at the cost of salience and legitimacy in the eyes of decision makers, and, third, different actors can have conflicting views about what constitutes legitimate information. We highlight 4 institutional frameworks that can facilitate science that will inform management: boundary organizations (environmental organizations that span the boundary between science and management), research scientists embedded in resource management agencies, formal links between decision makers and scientists at research-focused institutions, and training programs for conservation professionals. Although these are not the only approaches to generating boundary-spanning science, nor are they mutually exclusive, they provide mechanisms for promoting communication, translation, and mediation across the knowledge–action boundary. We believe that despite the challenges, conservation science should strive to be a boundary science, which

A method for calculating latent heats of fusion from binary diagrams of liquid-solid equilibrium was proposed several years ago by J. Bousquet and one of us. The method is base on the hypothesis of the regularity of the solution in a small region around the eutectic and involves an integration along the liquidus curves slightly extrapolated below the eutectic point.

Dire necessity and transformation: entry-points for modern science in Islamic bioethical assessment of porcine products in vaccines.

Science.gov (United States)

Padela, Aasim I; Furber, Steven W; Kholwadia, Mohammad A; Moosa, Ebrahim

2014-02-01

The field of medicine provides an important window through which to examine the encounters between religion and science, and between modernity and tradition. While both religion and science consider health to be a 'good' that is to be preserved, and promoted, religious and science-based teachings may differ in their conception of what constitutes good health, and how that health is to be achieved. This paper analyzes the way the Islamic ethico-legal tradition assesses the permissibility of using vaccines that contain porcine-derived components by referencing opinions of several Islamic authorities. In the Islamic ethico-legal tradition controversy surrounds the use of proteins from an animal (pig) that is considered to be impure by Islamic law. As we discuss the Islamic ethico-legal constructs used to argue for or against the use of porcine-based vaccines we will call attention to areas where modern medical data may make the arguments more precise. By highlighting areas where science can buttress and clarify the ethico-legal arguments we hope to spur an enhanced applied Islamic bioethics discourse where religious scholars and medical experts use modern science in a way that remains faithful to the epistemology of Islamic ethics to clarify what Islam requires of Muslim patients and healthcare workers. © 2013 John Wiley & Sons Ltd.

Bidirectional Associations Between Externalizing Behavior Problems and Maladaptive Parenting Within Parent-Son Dyads Across Childhood.

Science.gov (United States)

Besemer, Sytske; Loeber, Rolf; Hinshaw, Stephen P; Pardini, Dustin A

2016-10-01

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.

Full Text Available La creación de sistemas integradores de productos de investigación, como el Researcher ID de Thomson Reuters, ha sido una necesidad emergente debido a lo complejo que es para los investigadores demostrar de manera periódica el impacto y difusión de su investigación. Sin embargo, estos sistemas se alimentan de información proveniente de las diversas bases de datos y cada vez son más inclusivos para captar productos de investigación. Varios estudios bibliométricos han demostrado que las bases de datos contienen imprecisiones de varios tipos, que afectan directamente a los sistemas integradores. Como consecuencia, se plantea este estudio descriptivo con el fin de analizar la precisión de los registros del Researcher ID de los miembros del consejo de www.psy-wos.es y de una muestra de usuarios de esta página para cotejar los registros con los contenidos en la base de datos Web of Science, diferenciándolos de contenidos ajenos a esta base de datos. Los resultados reflejan que existen imprecisiones y errores considerables en los Researcher ID de la muestra analizada, tales como duplicidad de registros y la inclusión de registros ajenos a la Web of Science. Se concluye que los Resercher ID así como el www.psy-wos.es no son válidos ni fiables.

Turkel, Marian C; Watson, Jean; Giovannoni, Joseph

2018-01-01

The concepts caring science and science of caring have different meanings; however, they are often used interchangeably. The purpose of this paper is to present an overview of the synthesis of the scholarly literature on the definitions of the science of caring and caring science and to affirm the authors' perspective relating to the language of caring science. Caring science advances the epistemology and ontology of caring. Ideas related to caring science inquiry are presented, and the authors acknowledge the future of caring science as unitary caring science.

Kinematics of semiclassical spin and spin fiber bundle associated with so(n) Lie-Poisson manifold

International Nuclear Information System (INIS)

Deriglazov, A A

2013-01-01

We describe geometric construction underlying the Lagrangian actions for non-Grassmann spinning particles proposed in our recent works. If we discard the spatial variables (the case of frozen spin), the problem reduces to formulation of a variational problem for Hamiltonian system on a manifold with so(n) Lie-Poisson bracket. To achieve this, we identify dynamical variables of the problem with coordinates of the base of a properly constructed fiber bundle. In turn, the fiber bundle is embedded as a surface into the phase space equipped with canonical Poisson bracket. This allows us to formulate the variational problem using the standard methods of Dirac theory for constrained systems.

Parental choice: what parents want in a son-in-law and a daughter-in-law across 67 pre-industrial societies.

Science.gov (United States)

Apostolou, Menelaos

2010-11-01

Parents are influential over mate choice, and in most human societies they choose spouses for their offspring according to their own preferences. However, surprising little is known about the qualities which make a woman desirable as a daughter-in-law and a man desirable as a son-in-law. Using evidence from 67 societies such traits are identified and three hypotheses are tested: first, the hypothesis is tested that parents desire in an in-law qualities which are beneficial to them and their kin. Second, it is hypothesized that such preferences are contingent upon the sex of the in-law, as traits are weighted differently in a daughter-in-law and in a son-in-law. The third hypothesis tested is that parental preferences vary according to the subsistence type of a given society, as traits are valued differently in agropastoral societies and foraging societies. The evidence presented here provides support for all three hypotheses.

Wolfgang Pauli - a portrait. History of science; Wolfgang Pauli - ein Portrait. Wissenschaftsgeschichte

Fischer, E.P.

2008-07-01

Wolfgang Pauli (1900-1958) is named by his colleagues in the same breath with Isaac Newton and Albert Einstein, who named Pauli his ''mental son''. The history of science had neglected Pauli for a long time. The reason for this may be found in Pauli's attempts to capture the role of the unconscious in physics and the meaning of dreams in the creation of scientific pictures of the world. For Pauli a scientific method consisted in activating the unconscious and hoping that it would start up that specific type of ''painting viewing'' from which the terms can arise by which we express our understanding.

Complicity to Hegemonic Masculinity in D.H. Lawrence’s Sons and Lovers

Directory of Open Access Journals (Sweden)

Angelina Subrayan

2016-04-01

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. Keywords: Hegemonic Masculinity, Dominant Masculinity, Patriarchy, Gender, Power

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

Directory of Open Access Journals (Sweden)

Bubalo Đorđe

2009-01-01

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.

Application of the GRAAL model to leaching experiments with SON68 nuclear glass in initially pure water

International Nuclear Information System (INIS)

Frugier, P.; Chave, T.; Gin, S.; Lartigue, J.-E.

2009-01-01

Based on a review of the current state of knowledge concerning the aqueous alteration of SON68 nuclear glass we have proposed a mechanistic model, GRAAL (Glass Reactivity with Allowance for the Alteration Layer) [P. Frugier, S. Gin, Y. Minet, T. Chave, B. Bonin, N. Godon, J.E. Lartigue, P. Jollivet, A. Ayral, L. De Windt, G. Santarini, J. Nucl. Mater. 380 (2008) 8]. This article describes how the GRAAL model hypotheses are solved using a calculation code coupling chemistry and transport. The geochemical solution of this model combines three major phenomena: chemical equilibria in solution, water and ion transport by convection or diffusion, and element diffusion through the passivating reactive interphase. The model results are compared with experimental data for SON68 glass leached in initially pure water both in a closed system and in renewed media. The comparison shows the model very satisfactorily accounts for variations in the pH and the element concentrations in solution as a function of time, the glass surface area in contact with solution, and the solution renewal rate. This success is due to the fact that the diffusion of elements through the alteration gel is taken into account in the model. This mechanism cannot be disregarded under most experimental conditions - if only to predict the solution pH - and must therefore be an integral part of the geochemical model.

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.

What's science? Where's science? Science journalism in German print media.

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.

Les sciences cognitives ne sont pas des sciences humaines

Albert Ogien

cognitive sciences as well as humanities and social sciences. This critic relies upon the rebuttal of the three ideas backed by the authors: 1 the scientific description of cognitive elementary mechanisms gives a causal explanation of social conducts that must substitute itself to the ones of humanities and social sciences; 2 the use of naturalism allows a forgery of preconceived ideas the they continue to maintain; 3 the naturalization of the mind program doesn’t imply forms of reductionism. This triple critic allows a rejection of their appeal in favor of an integrated model of human conduct by putting forward a statement: since we do not know how to fill the gap that divides detailed descriptions of the working brain from the explanations of the individuals’ conducts and the ways in which they coordinate these personal conducts and the public ones, humanities and social sciences have little to gain from the cognitive sciences’ side in order to improve their analyses of action. It is because their work is located either at a subhuman level of molecular functioning or at a superhuman level of evolution; and only humanities and social sciences place their analyses simply at a human level by using humans as they live together as a measure of everything that concerns them. What they cannot do on a naturalist mode.Las ciencias cognitivas no son ciencias sobre la sociedad.Respuesta al artículo de Laurence Kaufman y Laurent Cordonier, « Vers un naturalisme social- Hacia un naturalismo social »En este artículo se analizan los límites del naturalismo social que Laurence Kaufman y Laurent Cordonier adoptan en esta revista, y se critican los argumentos para integrar los conocimientos de las ciencias cognitivas en las ciencias sociales.

"I am Not a Statistic": Identities of African American Males in Advanced Science Courses

Science.gov (United States)

Johnson, Diane Wynn

The United States Bureau of Labor Statistics (2010) expects new industries to generate approximately 2.7 million jobs in science and technology by the year 2018, and there is concern as to whether there will be enough trained individuals to fill these positions. A tremendous resource remains untapped, African American students, especially African American males (National Science Foundation, 2009). Historically, African American males have been omitted from the so called science pipeline. Fewer African American males pursue a science discipline due, in part; to limiting factors they experience in school and at home (Ogbu, 2004). This is a case study of African American males who are enrolled in advanced science courses at a predominantly African American (84%) urban high school. Guided by expectancy-value theory (EVT) of achievement related results (Eccles, 2009; Eccles et al., 1983), twelve African American male students in two advanced science courses were observed in their science classrooms weekly, participated in an in-depth interview, developed a presentation to share with students enrolled in a tenth grade science course, responded to an open-ended identity questionnaire, and were surveyed about their perceptions of school. Additionally, the students' teachers were interviewed, and seven of the students' parents. The interview data analyses highlighted the important role of supportive parents (key socializers) who had high expectations for their sons and who pushed them academically. The students clearly attributed their enrollment in advanced science courses to their high regard for their science teachers, which included positive relationships, hands-on learning in class, and an inviting and encouraging learning environment. Additionally, other family members and coaches played important roles in these young men's lives. Students' PowerPoint(c) presentations to younger high school students on why they should take advanced science courses highlighted these

Everyday science & science every day: Science-related talk & activities across settings

Science.gov (United States)

Zimmerman, Heather

To understand the development of science-related thinking, acting, and learning in middle childhood, I studied youth in schools, homes, and other neighborhood settings over a three-year period. The research goal was to analyze how multiple everyday experiences influence children's participation in science-related practices and their thinking about science and scientists. Ethnographic and interaction analysis methodologies were to study the cognition and social interactions of the children as they participated in activities with peers, family, and teachers (n=128). Interviews and participant self-documentation protocols elucidated the participants' understandings of science. An Everyday Expertise (Bell et al., 2006) theoretical framework was employed to study the development of science understandings on three analytical planes: individual learner, social groups, and societal/community resources. Findings came from a cross-case analysis of urban science learners and from two within-case analyses of girls' science-related practices as they transitioned from elementary to middle school. Results included: (1) children participated actively in science across settings---including in their homes as well as in schools, (2) children's interests in science were not always aligned to the school science content, pedagogy, or school structures for participation, yet children found ways to engage with science despite these differences through crafting multiple pathways into science, (3) urban parents were active supporters of STEM-related learning environments through brokering access to social and material resources, (4) the youth often found science in their daily activities that formal education did not make use of, and (5) children's involvement with science-related practices can be developed into design principles to reach youth in culturally relevant ways.

The Phenomenology of Trauma. Sound and Haptic Sensuality in Son of Saul

Vincze Teréz

2016-12-01

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

Meta-analysis suggests choosy females get sexy sons more than "good genes".

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.

The history of artificial recharge of groundwater in Majorca island is explained in this paper. Too, a brief description of the only experience now working is shown, and an overview of the proposal of the Hydrogeological Plan of the Demarcation of Baleares for the regulation of runoff by means of the artificial recharge of aquifers is presented. This should include Son Real and Binicaubell torrents; so, an assessment of their water surpluses to determine water availability for artificial recharge is analyzed. The methodology used is based on a climatic analysis in the studied basins, as well as on the Son Real y Binicaubell torrents water inflow.Water naturally infiltrated through these torrents' beds and surpluses flowing to the sea are also quantified. The statistical analysis involves methods such as autocorrelation. (Author) 20 refs.

Full Text Available Le Silence de la mer, écrit en 1941 et publié en 1942, est un livre culte qui a consacré son auteur Vercors – de son vrai nom Jean Bruller - comme un des écrivains de la Résistance. A la Libération, ce premier volume de la maison d’édition clandestine les Editions de Minuit, a été immédiatement réimprimé, puis suivi d’une adaptation théâtrale en 1949 dans une mise en scène de Jean Mercure, et du film très fidèle de Jean-Pierre Melville. Si on ne l’a pas lu, on en connaît du moins l’histoire, celle d’un officier allemand Werner von Ebrennac qu’un oncle et sa nièce sont obligés d’accueillir dans leur maison. Chaque soir, cet homme cultivé comble le silence, forme de résistance de ses hôtes, par ses monologues illusoires exprimant son espoir d’union entre l’Allemagne et la France. Quand il apprend finalement les véritables intentions de son pays, il se résigne, ce que le narrateur réprouve hautement, s’engage pour le front de l’est et quitte à jamais la nièce, symbole dans son esprit de cette France digne qu’il admire et aime tant.Ce livre incontournable, posé librement aujourd’hui sur les étagères des bibliothèques publiques et privées, a été largement commenté. Nous nous risquons néanmoins à proposer une nouvelle entrée : dans ce bref essai, nous nous permettrons de pénétrer dans ce récit par le biais de la bibliothèque qui trône majestueusement dans la salle de l’oncle et de sa nièce et nous essaierons de montrer que cet espace symbolique offre une circulation riche d’interprétations nombreuses de l’imaginaire du texte au réel le plus immédiat.

Full Text Available Fundamentos: El elevado número de personas que trabajando con ordenador utiliza lentes de contacto plantea la cuestión sobre si la suma de estos dos factores de riesgo para la salud visual puede originar un agravamiento del Síndrome Visual Informático. El objetivo de esta revisión es sintetizar el conocimiento científico sobre las alteraciones oculares y visuales relacionadas con la exposición a ordenador en usuarios de lentes de contacto. Métodos: Revisión de artículos científicos (2003-2013 en español e inglés, realizando una búsqueda bibliográfica, en Medline a través de PubMed y en Scopus. Resultados: La búsqueda inicial aportó 114 trabajos, después de aplicar criterios de inclusión/exclusión se incluyeron seis artículos. Todos ellos ponen de manifiesto que las alteraciones al utilizar el ordenador son más frecuentes en las personas usuarias de lentes de contacto, con prevalencias que oscilan de 95,0% al 16,9% que en las que no utilizan lentes de contacto, cuya prevalencia va del 57,5% al 9,9% y con una probabilidad cuatro veces mayor de padecer ojo seco [OR: 4,07 (IC 95%: 3,52-4,71]. Conclusiones: Las personas usuarias de ordenador padecen más alteraciones oculares y visuales cuando además son usuarias de lentes de contacto, pero los estudios son escasos y poco contundentes. Se precisan nuevas investigaciones que analicen la influencia según los tipos de lentes y sus condiciones de uso, tanto en la sintomatología como en la calidad de la lágrima y la superficie ocular. Las lentes de hidrogel de silicona son las que se asocian a mayor confort.

Achieving Open Access to Conservation Science

Science.gov (United States)

Fuller, Richard A; Lee, Jasmine R; Watson, James E M

2014-01-01

Conservation science is a crisis discipline in which the results of scientific enquiry must be made available quickly to those implementing management. We assessed the extent to which scientific research published since the year 2000 in 20 conservation science journals is publicly available. Of the 19,207 papers published, 1,667 (8.68%) are freely downloadable from an official repository. Moreover, only 938 papers (4.88%) meet the standard definition of open access in which material can be freely reused providing attribution to the authors is given. This compares poorly with a comparable set of 20 evolutionary biology journals, where 31.93% of papers are freely downloadable and 7.49% are open access. Seventeen of the 20 conservation journals offer an open access option, but fewer than 5% of the papers are available through open access. The cost of accessing the full body of conservation science runs into tens of thousands of dollars per year for institutional subscribers, and many conservation practitioners cannot access pay-per-view science through their workplace. However, important initiatives such as Research4Life are making science available to organizations in developing countries. We urge authors of conservation science to pay for open access on a per-article basis or to choose publication in open access journals, taking care to ensure the license allows reuse for any purpose providing attribution is given. Currently, it would cost $51 million to make all conservation science published since 2000 freely available by paying the open access fees currently levied to authors. Publishers of conservation journals might consider more cost effective models for open access and conservation-oriented organizations running journals could consider a broader range of options for open access to nonmembers such as sponsorship of open access via membership fees.

Science teaching in science education

Callahan, Brendan E.; Dopico, Eduardo

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.

Secondary science teachers' attitudes toward and beliefs about science reading and science textbooks

Science.gov (United States)

Yore, Larry D.

Science textbooks are dominant influences behind most secondary science instruction but little is known about teachers' approach to science reading. The purpose of this naturalistic study was to develop and validate a Science and Reading Questionnaire to assess secondary science teachers' attitudes toward science reading and their beliefs or informed opinions about science reading. A survey of 428 British Columbia secondary science teachers was conducted and 215 science teachers responded. Results on a 12-item Likert attitude scale indicated that teachers place high value on reading as an important strategy to promote learning in science and that they generally accept responsibility for teaching content reading skills to science students. Results on a 13-item Likert belief scale indicated that science teachers generally reject the text-driven model of reading, but they usually do not have well-formulated alternative models to guide their teaching practices. Teachers have intuitive beliefs about science reading that partially agree with many research findings, but their beliefs are fragmented and particularly sketchy in regard to the cognitive and metacognitive skills required by readers to learn from science texts. The findings for attitude, belief, and total scales were substantiated by further questions in the Science and Reading Questionnaire regarding classroom practice and by individual interviews and classroom observations of a 15-teacher subsample of the questionnaire respondents.

The construct of 'preparation for future learning' (PFL) is understood as the ability to learn new information from available resources, relate new learning to past experiences and demonstrate innovation and flexibility in problem solving. Preparation for future learning has been proposed as a key competence of adaptive expertise. There is a need for educators to ensure that opportunities are provided for students to develop PFL ability and that assessments accurately measure the development of this form of competence. The objective of this research was to compare the relative impacts of basic science instruction and clinically focused instruction on performance on a PFL assessment (PFLA). This study employed a 'double transfer' design. Fifty-one pre-clerkship students were randomly assigned to either basic science instruction or clinically focused instruction to learn four categories of disease. After completing an initial assessment on the learned material, all participants received clinically focused instruction for four novel diseases and completed a PFLA. The data from the initial assessment and the PFLA were submitted to independent-sample t-tests. Mean ± standard deviation [SD] scores on the diagnostic cases in the initial assessment were similar for participants in the basic science (0.65 ± 0.11) and clinical learning (0.62 ± 0.11) conditions. The difference was not significant (t[42] = 0.90, p = 0.37, d = 0.27). Analysis of the diagnostic cases on the PFLA revealed significantly higher mean ± SD scores for participants in the basic science learning condition (0.72 ± 0.14) compared with those in the clinical learning condition (0.63 ± 0.15) (t[42] = 2.02, p = 0.05, d = 0.62). Our results show that the inclusion of basic science instruction enhanced the learning of novel related content. We discuss this finding within the broader context of research on basic science instruction, development of adaptive expertise and assessment

The European Federation for Pharmaceutical Sciences (EUFEPS) was founded 25 years ago by more than 20 national pharmaceutical societies and faculty members. As a pan-European organization, it brings together pharmaceutical societies as well as academic, industrial and regulatory scientists engaged in drug research and development, drug regulation and education of professionals working in these fields. EUFEPS represents pharmaceutical sciences in Europe and is recognized as such by both the European Commission and the European Medicines Agency. EUFEPS cooperates with the European Federation of Pharmaceutical Industries and other European organizations and maintains global connections with agencies such as the US Food and Drug Administration and the American Association of Pharmaceutical Scientists. EUFEPS has established specified networks forming the basis of its activities. The creation of a Network on Veterinary Medicines is prompted by the manifold problems resulting from the use of veterinary drugs and its inherent interconnections with human medicine, environmental and public health. A long-term goal of this initiative was to expand the spectrum of available therapeutics for use in animals, including the development of innovative delivery systems. © 2017 John Wiley & Sons Ltd.

Expression of multiple sexual signals by fathers and sons in the East-Mediterranean barn swallow: are advertising strategies heritable?

Science.gov (United States)

Vortman, Yoni; Safran, Rebecca J; Reiner Brodetzki, Tali; Dor, Roi; Lotem, Arnon

2015-01-01

The level of expression of sexually selected traits is generally determined by genes, environment and their interaction. In species that use multiple sexual signals which may be costly to produce, investing in the expression of one sexual signal may limit the expression of the other, favoring the evolution of a strategy for resource allocation among signals. As a result, even when the expression of sexual signals is condition dependent, the relative level of expression of each signal may be heritable. We tested this hypothesis in the East-Mediterranean barn swallow (Hirundo rustica transitiva), in which males have been shown to express two uncorrelated sexual signals: red-brown ventral coloration, and long tail streamers. We show that variation in both signals may partially be explained by age, as well as by paternal origin (genetic father-son regressions), but that the strongest similarity between fathers and sons is the relative allocation towards one trait or the other (relative expression index), rather than the expression of the traits themselves. These results suggest that the expression of one signal is not independent of the other, and that genetic strategies for resource allocation among sexual signals may be selected for during the evolution of multiple sexual signals.

Science Olympiad students' nature of science understandings

Science.gov (United States)

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.

Signal transmission by insulin involves tyrosine phosphorylation of a major insulin receptor substrate (IRS-1) and exchange of Ras-bound guanosine diphosphate for guanosine triphosphate. Proteins containing Src homology 2 and 3 (SH2 and SH3) domains, such as the p85 regulatory subunit of phosphatidylinositol-3 kinase and growth factor receptor-bound protein 2 (GRB2), bind tyrosine phosphate sites on IRS-1 through their SH2 regions. Such complexes in COS cells were found to contain the heterologously expressed putative guanine nucleotide exchange factor encoded by the Drosophila son of sevenless gene (dSos). Thus, GRB2, p85, or other proteins with SH2-SH3 adapter sequences may link Sos proteins to IRS-1 signaling complexes as part of the mechanism by which insulin activates Ras.

Congenital contractural arachnodactyly (Beals syndrome) is a rare autosomal dominantly inherited connective tissue disorder characterized by flexion contractures, arachnodactyly, crumpled ears, and mild muscular hypoplasia. Here, a father and son with congenital contractural arachnodactyly features were identified. After sequencing 15 exons (22 to 36) of the FBN2 gene, a novel mutation (C1425Y) was found in exon 33. This de novo mutation presented first in the father and was transmitted to his son, but not in the other 14 unaffected family members and 365 normal people. The C1425Y mutation occurs at the 19th cbEGF domain. Cysteines in this cbEGF domain are rather conserved in species, from human down to ascidian. The cbEGF12-13 in human FBN1 was employed as the template to perform homology modeling of cbEGF18-19 of human FBN2 protein. The mutation has also been evaluated by further prediction tools, for example, SIFT, Blosum62, biochemical Yu's matrice, and UMD-Predictor tool. In all analysis, the mutation is predicted to be pathogenic. Thus, the structure destabilization by C1425Y might be the cause of the disorder.

Introducing SONS, a tool for operational taxonomic unit-based comparisons of microbial community memberships and structures.

Schloss, Patrick D; Handelsman, Jo

2006-10-01

The recent advent of tools enabling statistical inferences to be drawn from comparisons of microbial communities has enabled the focus of microbial ecology to move from characterizing biodiversity to describing the distribution of that biodiversity. Although statistical tools have been developed to compare community structures across a phylogenetic tree, we lack tools to compare the memberships and structures of two communities at a particular operational taxonomic unit (OTU) definition. Furthermore, current tests of community structure do not indicate the similarity of the communities but only report the probability of a statistical hypothesis. Here we present a computer program, SONS, which implements nonparametric estimators for the fraction and richness of OTUs shared between two communities.

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. It includes references to original research papers, landmark scie...

Science Song Project: Integration of Science, Technology and Music to Learn Science and Process Skills

Full Text Available It has been critical to find a way for teachers to motivate their young children to learn science and improve science achievement. Since music has been used as a tool for educating young students, this study introduces the science song project to teacher candidates that contains science facts, concepts, laws and theories, and combines them with music for motivating their young children to learn science and improve science achievement. The purpose of the study is to determine the effect of the science song project on teacher candidates’ understanding of science processing skills and their attitudes toward science. The participants were 45 science teacher candidates who were enrolled in an EC-6 (Early Childhood through Grade 6 program in the teacher certification program at a racially diverse Texas public research university. To collect data, this study used two instruments: pre-and post-self efficacy tests before and after the science teacher candidates experienced the science song project and final reflective essay at the end of the semester. The results show that while developing their songs, the participating teacher candidates experienced a process for science practice, understood science concepts and facts, and positively improved attitudes toward science. This study suggests that the science song project is a science instruction offering rich experiences of process-based learning and positive attitudes toward science.

‘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.

How to Motivate Science Teachers to Use Science Experiments

Directory of Open Access Journals (Sweden)

Josef Trna

2012-10-01

Full Text Available A science experiment is the core tool in science education. This study describes the science teachers' professional competence to implement science experiments in teaching/learning science. The main objective is the motivation of science teachers to use science experiments. The presented research tries to answer questions aimed at the science teachers' skills to use science experiments in teaching/learning science. The research discovered the following facts: science teachers do not include science experiments in teaching/learning in a suitable way; are not able to choose science experiments corresponding to the teaching phase; prefer teachers' demonstration of science experiments; are not able to improvise with the aids; use only a few experiments. The important research result is that an important motivational tool for science teachers is the creation of simple experiments. Examples of motivational simple experiments used into teachers' training for increasing their own creativity and motivation are presented.

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.

Hollywood Science: Good for Hollywood, Bad for Science?

Perkowitz, Sidney

2009-03-01

Like it or not, most science depicted in feature films is in the form of science fiction. This isn't likely to change any time soon, if only because science fiction films are huge moneymakers for Hollywood. But beyond that, these films are a powerful cultural force. They reach millions as they depict scientific ideas from DNA and cloning to space science, whether correctly or incorrectly; reflect contemporary issues of science and society like climate change, nuclear power and biowarfare; inspire young people to become scientists; and provide defining images -- or stereotypes -- of scientists for the majority of people who've never met a real one. Certainly, most scientists feel that screen depictions of science and scientists are badly distorted. Many are, but not always. In this talk, based on my book Hollywood Science [1], I'll show examples of good and bad screen treatments of science, scientists, and their impact on society. I'll also discuss efforts to improve how science is treated in film and ways to use even bad movie science to convey real science.

J. M. W. Turner's painting "The unpaid bill, or the dentist reproving his son's prodigality".

Science.gov (United States)

Bishop, M; Gelbier, S; King, J

2004-12-25

In November 2002, the BDA News carried an item, illustrated with a colour reproduction, describing a painting of a Georgian dentist's rooms by Joseph Mallord William Turner (1775-1851), one of the most respected of English artists, which was shortly to come up for auction at Christies' Rooms in London. This work, first exhibited in 1808, was entitled "The unpaid bill, or the dentist reproving his son's prodigality", and had originally been commissioned by the connoisseur Richard Payne Knight (1750-1824). "The examiner", a contemporary London journal, identifies the 'cradle-piece' for the commission as being a Rembrandt which Payne Knight owned, and the journalist Robert Hunt said that Turner had more than come up to the task of showing that a modern could handle light as well as the old master, 'for a picture of colouring and effect, it is ... inestimable'.

(Alpha, gamma) irradiation effect on the alteration of high-level radioactive wastes matrices (UO2, hollandite, glass SON68)

International Nuclear Information System (INIS)

Suzuki, T.

2007-06-01

The aim of this work is to determine the effect of irradiation on the alteration of high level nuclear waste forms matrices. The matrices investigated are UO 2 to simulate the spent fuel, the hollandite for the specific conditioning of Cs, and the inactive glass SON68 representing the nuclear glass R7T7) The alpha irradiation experiments on UO 2 colloids in aqueous carbonate media have enabled to distinguish between the oxidation of UO 2 matrix as initial and dissolution as subsequent step. The simultaneous presence of carbonate and H 2 O 2 (product resulting from water radiolysis) increased the dissolution rate of UO 2 to its maximum value governed by the oxidation rate. ii) The study of hollandite alteration under gamma irradiation confirmed the good retention capacity for Cs and Ba. Gamma irradiation had brought only a little influence on releasing of Cs and Ba in solution. Electronic irradiation had conducted to the amorphization of the hollandite only for a dose 1000 times higher than the auto-induced dose of Ba over millions of years. iii) The experiences of glass irradiation under alpha beam and of helium implantation in the glass SON68 were analyzed by positon annihilation spectroscopy. No effect has been observed on the solid surface for an irradiation dose equal to 1000 years of storage. (author)

Does science education need the history of science?

Gooday, Graeme; Lynch, John M; Wilson, Kenneth G; Barsky, Constance K

2008-06-01

This essay argues that science education can gain from close engagement with the history of science both in the training of prospective vocational scientists and in educating the broader public about the nature of science. First it shows how historicizing science in the classroom can improve the pedagogical experience of science students and might even help them turn into more effective professional practitioners of science. Then it examines how historians of science can support the scientific education of the general public at a time when debates over "intelligent design" are raising major questions over the kind of science that ought to be available to children in their school curricula. It concludes by considering further work that might be undertaken to show how history of science could be of more general educational interest and utility, well beyond the closed academic domains in which historians of science typically operate.

Father and son attachment styles in alcoholic and non-alcoholic families

Directory of Open Access Journals (Sweden)

Mythili Hazarika

2017-12-01

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.

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.

The discovery of X-ray diffraction by crystals and its great impact on science

International Nuclear Information System (INIS)

Mai Zhenhong

2012-01-01

In April 1912, Friedrich, Knipping and Laue discovered X-ray diffraction in a CuSO 4 crystal. Later, Laue derived the famous Laue equations which explain the diffraction phenomenon. For this, Laue was awarded a Nobel Prize for Physics in 1914. In 1912 W. H. Bragg and W. L. Bragg received news of Laue 's discovery, and from X-ray diffraction experiments in a ZnS crystal they derived the famous Bragg equation. For this work, father and son were together awarded the Nobel Prize for Physics in 1915, To commemorate the 100th anniversary of the discovery of X-ray diffraction, this article reviews the important contributions of the early pioneers and their historic impact on science and technology worldwide.

Constructing a philosophy of science of cognitive science.

Science.gov (United States)

Bechtel, William

2009-07-01

Philosophy of science is positioned to make distinctive contributions to cognitive science by providing perspective on its conceptual foundations and by advancing normative recommendations. The philosophy of science I embrace is naturalistic in that it is grounded in the study of actual science. Focusing on explanation, I describe the recent development of a mechanistic philosophy of science from which I draw three normative consequences for cognitive science. First, insofar as cognitive mechanisms are information-processing mechanisms, cognitive science needs an account of how the representations invoked in cognitive mechanisms carry information about contents, and I suggest that control theory offers the needed perspective on the relation of representations to contents. Second, I argue that cognitive science requires, but is still in search of, a catalog of cognitive operations that researchers can draw upon in explaining cognitive mechanisms. Last, I provide a new perspective on the relation of cognitive science to brain sciences, one which embraces both reductive research on neural components that figure in cognitive mechanisms and a concern with recomposing higher-level mechanisms from their components and situating them in their environments.

Informal science education at Science City

Science.gov (United States)

French, April Nicole

The presentation of chemistry within informal learning environments, specifically science museums and science centers is very sparse. This work examines learning in Kansas City's Science City's Astronaut Training Center in order to identify specific behaviors associated with visitors' perception of learning and their attitudes toward space and science to develop an effective chemistry exhibit. Grounded in social-constructivism and the Contextual Model of Learning, this work approaches learning in informal environments as resulting from social interactions constructed over time from interaction between visitors. Visitors to the Astronaut Training Center were surveyed both during their visit and a year after the visit to establish their perceptions of behavior within the exhibit and attitudes toward space and science. Observations of visitor behavior and a survey of the Science City staff were used to corroborate visitor responses. Eighty-six percent of visitors to Science City indicated they had learned from their experiences in the Astronaut Training Center. No correlation was found between this perception of learning and visitor's interactions with exhibit stations. Visitor attitudes were generally positive toward learning in informal settings and space science as it was presented in the exhibit. Visitors also felt positively toward using video game technology as learning tools. This opens opportunities to developing chemistry exhibits using video technology to lessen the waste stream produced by a full scale chemistry exhibit.

Ordinary citizens form quadrillions of correct beliefs on matters that turn on complicated scientific principles they cannot even identify much less understand. The reason they fail to converge on beliefs consistent with scientific evidence on certain other consequential matters—from climate change to genetically modified foods to compusory adolescent HPV vaccination—is not the failure of scientists or science communicators to speak clearly or the inability of ordinary citizens to understand what they are saying. Rather, the source of such conflict is the proliferation of antagonistic cultural meanings. When they become attached to particular facts that admit of scientific investigation, these meanings are a kind of pollution of the science communication environment that disables the faculties ordinary citizens use to reliably absorb collective knowledge from their everyday interactions. The quality of the science communication environment is thus just as critical for enlightened self-government as the quality of the natural environment is for the physical health and well-being of a society's members. Understanding how this science communication environment works, fashioning procedures to prevent it from becoming contaminated with antagonistic meanings, and formulating effective interventions to detoxify it when protective strategies fail—those are the most critical functions science communication can perform in a democratic society.

Carpenter, Wendy Renae

The purpose for conducting this qualitative study was to explore best practices of exemplary standards-based science programs and instructional leadership practices in a charter high school and in a traditional high school. The focus of this study included how twelve participants aligned practices to National Science Education Standards to describe their science programs and science instructional practices. This study used a multi-site case study qualitative design. Data were obtained through a review of literature, interviews, observations, review of educational documents, and researcher's notes collected in a field log. The methodology used was a multi-site case study because of the potential, through cross analysis, for providing greater explanation of the findings in the study (Merriam, 1988). This study discovered six characteristics about the two high school's science programs that enhance the literature found in the National Science Education Standards; (a) Culture of expectations for learning-In exemplary science programs teachers are familiar with a wide range of curricula. They have the ability to examine critically and select activities to use with their students to promote the understanding of science; (b) Culture of varied experiences-In exemplary science programs students are provided different paths to learning, which help students, take in information and make sense of concepts and skills that are set forth by the standards; (c) Culture of continuous feedback-In exemplary science programs teachers and students work together to engage students in ongoing assessments of their work and that of others as prescribed in the standards; (d) Culture of Observations-In exemplary science programs students, teachers, and principals reflect on classroom instructional practices; teachers receive ongoing evaluations about their teaching and apply feedback towards improving practices as outlined in the standards; (e) Culture of continuous learning-In exemplary

Unhealthy maternal lifestyle during pregnancy such as smoking, high prepregnancy body mass index (BMI as well as alcohol and caffeine intake may constitute possible risk factors for cryptorchidism, but results from the few previous studies are conflicting. We aimed to explore the association between maternal lifestyle factors and occurrence of cryptorchidism in sons.Patients and methods: The Danish National Birth Cohort and the Aarhus Birth Cohort provided information on maternal lifestyle from early pregnancy. Data were linked to several Danish health registers, multiple imputation was used to handle missing data and Cox proportional hazards models were used to adjust for potential confounders.Results: In total, 85,923 boys were included, and of them, 2.2% were diagnosed with cryptorchidism. We observed the strongest associations between maternal tobacco smoking and prepregnancy BMI and cryptorchidism. Sons of women who smoked 10–14 cigarettes/day had the highest hazard ratio (HR for cryptorchidism (1.37; 95% CI: 1.06–1.76, and for maternal BMI ≥30 kg/m2, the HR was 1.32 (95% CI: 1.06–1.65. Binge drinking was associated with an HR <1, if the women had one or two episodes in pregnancy (HR: 0.81; 95% CI: 0.67–0.98. Average maternal alcohol intake

Science for Diplomacy, Diplomacy for Science

Colglazier, E. Wiliam

I was a strong proponent of ``science diplomacy'' when I became Science and Technology Adviser to the Secretary of State in 2011. I thought I knew a lot about the subject after being engaged for four decades on international S&T policy issues and having had distinguished scientists as mentors who spent much of their time using science as a tool for building better relations between countries and working to make the world more peaceful, prosperous, and secure. I learned a lot from my three years inside the State Department, including great appreciation and respect for the real diplomats who work to defuse conflicts and avoid wars. But I also learned a lot about science diplomacy, both using science to advance diplomacy and diplomacy to advance science. My talk will focus on the five big things that I learned, and from that the one thing where I am focusing my energies to try to make a difference now that I am a private citizen again.

In this study, 156 participants, predominantly White British adults (M age = 44.3 years) rated themselves on overall IQ and on H. Gardner's (1983) 7 intelligence subtypes. Parents (n = 120) also estimated the intelligence of their children. Men's self-estimates were significantly higher than women's (110.15 vs. 104.84). Participants thought their verbal, mathematical, and spatial intelligence scores were the best indicators of their own overall intelligence. Parents estimated that their sons had significantly higher IQs than their daughters (115.21 vs. 107.49). Self-estimates and estimates of children's multiple intelligences were higher for men and sons, significantly so for logical-mathematical and spatial intelligence. Parents rated 2nd-born daughters as having significantly higher verbal and musical intelligence than their male counterparts. Higher parental IQ self-estimates corresponded with higher IQ estimates for children. Results for 1st-born children were clearest and showed the most significant differences. The findings are interpreted in terms of sociocultural and familial influences and the possibility of actual sex differences in particular abilities.

2008-01-01

This study was aimed at understanding the life of a mother who lost their child in violent circumstances. The methodological proceedings were supported on phenomenology. The study population was constituted by five mothers who had lost its young children for homicide. These homicides occurred different times ranging from 50 days to 10 years. I used as instrument of collection of data open interview the phenomenological method guided by a orienting question. The analysis phenomenology in their discourses showed the comprehension of essential meanings which were systematized in categories: the child's mummification in the memory; the two ways followed by the publicity concerning the death; fondness to spirituality to endure the pain from the child's death; maternal complicity and impunity. The results of this study can contribute to elaboration of intervention proposals close to the mothers in the sense of helping them in the reorganization of their lives after son's death.

This article summarizes the present state of knowledge concerning aqueous alteration of R7T7-type nuclear containment glasses, represented mainly by the inactive reference glass designated SON68. Based on this review, we propose to describe the glass alteration kinetics up to and including the final residual rate regime by means of a new mechanistic model known as GRAAL (glassreactivitywithallowanceforthealterationlayer). Phenomenological analysis findings are reviewed for the various glass alteration regimes: interdiffusion, initial rate, rate drop, residual rate and, under very particular circumstances, resumption of alteration. These alteration regimes are associated with predominant mechanisms. Published work interpreting and modeling these mechanisms was examined in detail. There is a broad consensus on the general mechanisms of the initial rate and even the interdiffusion regime, whereas the mechanisms controlling the rate drop remain a subject of dispute not only with regard to nuclear glasses but also for the dissolution of silicate minerals. The reaction affinity responsible for the rate drop is expressed differently by different authors and depending on the underlying theories. The disagreement concerns the nature of the phase (glass or gel) or the activated complex controlling the rate drop, which in turn determines the elements that must be taken into account in the overall affinity term. Progress in recent years, especially in identifying the mechanisms responsible for the residual rate, has shed new light on these issues, allowing us to propose new theoretical foundations for modeling the different kinetic regimes of SON68 nuclear glass dissolution. The GRAAL model considers that water diffusion in the passivating reaction zone (the gel formed under saturation conditions) is a rate-limiting step in the overall glass dissolution kinetics. Moreover, this passivation zone is a soluble phase whose stability is directly dependent on the nature of the

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.

Engineering behaviour change in an epidemic: the epistemology of NIH-funded HIV prevention science.

Science.gov (United States)

Green, Adam; Kolar, Kat

2015-05-01

Social scientific and public health literature on National Institutes of Health-funded HIV behavioural prevention science often assumes that this body of work has a strong biomedical epistemological orientation. We explore this assumption by conducting a systematic content analysis of all NIH-funded HIV behavioural prevention grants for men who have sex with men between 1989 and 2012. We find that while intervention research strongly favours a biomedical orientation, research into the antecedents of HIV risk practices favours a sociological, interpretive and structural orientation. Thus, with respect to NIH-funded HIV prevention science, there exists a major disjunct in the guiding epistemological orientations of how scientists understand HIV risk, on the one hand, and how they engineer behaviour change in behavioural interventions, on the other. Building on the extant literature, we suggest that the cause of this disjunct is probably attributable not to an NIH-wide positivist orientation, but to the specific standards of evidence used to adjudicate HIV intervention grant awards, including randomised controlled trials and other quantitative measures of intervention efficacy. © 2015 The Authors.

Responsiveness to citizens as users of technological innovation helps motivate translational research and commercial engagement among academics. Yet, retaining citizen trust and support for research encourages caution in pursuit of commercial science. We explore citizen expectations of the specifically academic nature of commercial science [i.e. academic entrepreneurship (AE)] and the influence of conflict of interest concerns, hopes about practical benefits and general beliefs. We conducted a cross-sectional national opinion survey of 1002 Canadians online in 2010. Approval of AE was moderate (mean 3.2/5, SD 0.84), but varied by entrepreneurial activity. Concern about conflict of interests (COI) was moderate (mean 2.9/5, SD 0.86) and varied by type of concern. An ordinary least-squares regression showed that expectations of practical benefits informed support for AE, specifically that academic-industry collaboration can better address real-world problems; conflict of interest concerns were insignificant. These findings suggest that citizens support AE for its potential to produce practical benefits, but enthusiasm varies and is reduced for activities that may prioritize private over public interests. Further, support exists despite concern about COI, perhaps due to trust in the academic research context. For user engagement in research priority setting, these findings suggest the need to attend to the commercial nature of translational science. For research policy, they suggest the need for governance arrangements for responsible innovation, which can sustain public trust in academic research, and realize the practical benefits that inform public support for AE. © 2014 John Wiley & Sons Ltd.

[Inspired by Apollo and Asclepio's sons in Homer and Virgil].

Merlino, R L

1989-01-01

Important passages of the Homeric and Virgilian epic are regarding the art of divination and the medical science, and underline contextually the figures of the fortune teller and that of the physician. Two roles are associated to one matrix: heroic-aristocratic or royal-sacerdotal. In Homer's epic it is possible to single out surgical and phytotherapeutic knowledge together with remedies for diseases aroused by a solar god, like Apollo is, gods' physician. Pitiful divinities comfort those who have been struck by demoniac and mysterious forms. On the contrary, in Virgil's epic a symbiosis is carried out between the physician's figure and the priest's one, with the very vague outlines of the two arts and however, overloaded by factors which are typically Virgilian. Unusual form of incubation of the Greek rituals has been transplanted in the Latin matrix; and moreover there is a constant recall of words used in their most antique meaning.

The desire to predict discoveries-to have some idea, in advance, of what will be discovered, by whom, when, and where-pervades nearly all aspects of modern science, from individual scientists to publishers, from funding agencies to hiring committees. In this Essay, we survey the emerging and interdisciplinary field of the "science of science" and what it teaches us about the predictability of scientific discovery. We then discuss future opportunities for improving predictions derived from the science of science and its potential impact, positive and negative, on the scientific community.

Can citizen science enhance public understanding of science?

Bonney, Rick; Phillips, Tina B; Ballard, Heidi L; Enck, Jody W

2016-01-01

Over the past 20 years, thousands of citizen science projects engaging millions of participants in collecting and/or processing data have sprung up around the world. Here we review documented outcomes from four categories of citizen science projects which are defined by the nature of the activities in which their participants engage - Data Collection, Data Processing, Curriculum-based, and Community Science. We find strong evidence that scientific outcomes of citizen science are well documented, particularly for Data Collection and Data Processing projects. We find limited but growing evidence that citizen science projects achieve participant gains in knowledge about science knowledge and process, increase public awareness of the diversity of scientific research, and provide deeper meaning to participants' hobbies. We also find some evidence that citizen science can contribute positively to social well-being by influencing the questions that are being addressed and by giving people a voice in local environmental decision making. While not all citizen science projects are intended to achieve a greater degree of public understanding of science, social change, or improved science -society relationships, those projects that do require effort and resources in four main categories: (1) project design, (2) outcomes measurement, (3) engagement of new audiences, and (4) new directions for research. © The Author(s) 2015.

Citizen Science: Opportunities for Girls' Development of Science Identity

Science.gov (United States)

Brien, Sinead Carroll

Many students in the United States, particularly girls, have lost interest in science by the time they reach high school and do not pursue higher degrees or careers in science. Several science education researchers have found that the ways in which youth see themselves and position themselves in relation to science can influence whether they pursue science studies and careers. I suggest that participation in a citizen science program, which I define as a program in which girls interact with professional scientists and collect data that contributes to scientific research, could contribute to changing girls' perceptions of science and scientists, and promote their science identity work. I refer to science identity as self-recognition and recognition by others that one thinks scientifically and does scientific work. I examined a case study to document and analyze the relationship between girls' participation in a summer citizen science project and their development of science identity. I observed six girls between the ages of 16 and 18 during the Milkweed and Monarch Project, taking field notes on focal girls' interactions with other youth, adults, and the scientist, conducted highly-structured interviews both pre-and post- girls' program participation, and interviewed the project scientist and educator. I qualitatively analyzed field notes and interview responses for themes in girls' discussion of what it meant to think scientifically, roles they took on, and how they recognized themselves as thinking scientifically. I found that girls who saw themselves as thinking scientifically during the program seemed to demonstrate shifts in their science identity. The aspects of the citizen science program that seemed to most influence shifts in these girls' science identities were 1) the framing of the project work as "real science, 2) that it involved ecological field work, and 3) that it created a culture that valued data and scientific work. However, some of the girls only

Identifying Relevant Anti-Science Perceptions to Improve Science-Based Communication: The Negative Perceptions of Science Scale

Directory of Open Access Journals (Sweden)

Melanie Morgan

2018-04-01

Full Text Available Science communicators and scholars have struggled to understand what appears to be increasingly frequent endorsement of a wide range of anti-science beliefs and a corresponding reduction of trust in science. A common explanation for this issue is a lack of science literacy/knowledge among the general public (Funk et al. 2015. However, other possible explanations have been advanced, including conflict with alternative belief systems and other contextual factors, and even cultural factors (Gauchat 2008; Kahan 2015 that are not necessarily due to knowledge deficits. One of the challenges is that there are limited tools available to measure a range of possible underlying negative perceptions of science that could provide a more nuanced framework within which to improve communication around important scientific topics. This project describes two studies detailing the development and validation of the Negative Perceptions of Science Scale (NPSS, a multi-dimensional instrument that taps into several distinct sets of negative science perceptions: Science as Corrupt, Science as Complex, Science as Heretical, and Science as Limited. Evidence for the reliability and validity of the NPSS is described. The sub-dimensions of the NPSS are associated with a range of specific anti-science beliefs across a broad set of topic areas above and beyond that explained by demographics (including education, sex, age, and income, political, and religious ideology. Implications for these findings for improving science communication and science-related message tailoring are discussed.

The evolution of the short- and medium-range local environment of lanthanum was determined by L-III-edge X-ray absorption spectroscopy (XAS) during leaching of simplified SON68-type glasses. In glass without phosphorus, lanthanum is found in a silicate environment, and its first coordination sphere comprises eight oxygen atoms at a mean distance of 2.51 angstrom. When this glass was leached at a high renewal rate, the lanthanum local environment was significantly modified: it was present at hydroxy-carbonate and silicate sites with a mean La-O distance of 2.56 angstrom, and the second neighbors consisted of La atoms instead of Si for the glass. Conversely, in the gel formed at low renewal rates, lanthanum was found in a silicate environment similar to that of the glass. In phosphorus-doped glass, lanthanum is found in a phosphate environment, although the Si/P atomic ratio is 20:1. Lanthanum is surrounded by seven oxygen atoms at a mean distance of 2.37 angstrom. When phosphorus-doped glass is leached, regardless of the leaching solution flow rate, the short- and medium-range lanthanum local environment remains almost constant; the most significant change is a 0.05 angstrom increase in the La-O distance.

While the literature is replete with studies examining teacher knowledge and pedagogical content knowledge (PCK), few studies have investigated how science teacher orientations (STOs) shape classroom instruction. Therefore, this research explores the interplay between a STOs and the topic specificity of PCK across two science topics within a grade 9 earth science course. Through interviews and observations of one teacher's classroom across two sequentially taught, this research contests the notion that teachers hold a single way of conceptualising science teaching and learning. In this, we consider if multiple ontologies can provide potential explanatory power for characterising instructional enactments. In earlier work with the teacher in this study, using generic interview prompts and general discussions about science teaching and learning, we accepted the existence of a unitary STO and its promise of consistent reformed instruction in the classroom. However, upon close examination of instruction focused on different science topics, evidence was found to demonstrate the explanatory power of multiple ontologies for shaping characteristically different epistemological constructions across science topics. This research points to the need for care in generalising about teacher practice, as it reveals that a teacher's practice, and orientation, can vary, dependent on the context and science topics taught.

Prior longitudinal and correlational research with adults and adolescents indicates that spatial ability is a predictor of science learning and achievement. However, there is little research to date with primary-school aged children that addresses this relationship. Understanding this association has the potential to inform curriculum design and support the development of early interventions. This study examined the relationship between primary-school children's spatial skills and their science achievement. Children aged 7-11 years (N = 123) completed a battery of five spatial tasks, based on a model of spatial ability in which skills fall along two dimensions: intrinsic-extrinsic; static-dynamic. Participants also completed a curriculum-based science assessment. Controlling for verbal ability and age, mental folding (intrinsic-dynamic spatial ability), and spatial scaling (extrinsic-static spatial ability) each emerged as unique predictors of overall science scores, with mental folding a stronger predictor than spatial scaling. These spatial skills combined accounted for 8% of the variance in science scores. When considered by scientific discipline, mental folding uniquely predicted both physics and biology scores, and spatial scaling accounted for additional variance in biology and variance in chemistry scores. The children's embedded figures task (intrinsic-static spatial ability) only accounted for variance in chemistry scores. The patterns of association were consistent across the age range. Spatial skills, particularly mental folding, spatial scaling, and disembedding, are predictive of 7- to 11-year-olds' science achievement. These skills make a similar contribution to performance for each age group. © 2018 The Authors.
