    2013-01-01

    BACKGROUND Although sons are thought to impose greater physiological costs on mothers than daughters, sons may be advantageous for parental survival in some social contexts. We examined the relationship between the sex composition of offspring and parental survival in contemporary China and Taiwan. Because of the importance of sons for the provision of support to elderly parents in these populations, we hypothesized that sons would have a beneficial effect on parental survival relative to daughters. METHODS We used data from the Chinese Longitudinal Healthy Longevity Survey (CLHLS) and the Taiwan Longitudinal Study of Aging (TLSA). Our CLHLS sample consisted of 4132 individuals ages 65+ in 2002. Our TLSA sample comprised two cohorts: 3409 persons aged 60+ in 1989 and 2193 persons aged 5066 in 1996.These cohorts were followed for 3, 18, and 11 years, respectively. We used Cox proportional hazards models to estimate the relationship between the sex composition of offspring and parental mortality. RESULTS Based on 7 measures of sex composition, we find no protective effect of sons in either China or Taiwan. For example, in the 1989 Taiwan sample, the hazard ratio for maternal mortality associated with having an eldest son is 0.979 (95% CI (0.863, 1.111)). In Taiwan, daughters may have been more beneficial than sons in reducing mortality in recent years. CONCLUSION We offer several explanations for these findings, including possible benefits associated with emotional and interpersonal forms of support provided by daughters and negative impacts of conflicts arising between parents and resident daughters-in-law.

    1993-11-01

    A Southern African feminist recounts how one morning her son objected to her blouse. She calmly informed him that just as he has the right to choose his outfits so does she. Since then he has not commented on her choice of clothes, but has made comments on how she dances, does her hair, and the length of her skirts/dresses. He has already taken on the male behavior of forging women's identity by remarking on their looks. She insists on a democratic relationship with her son which includes letting him makes choices (e.g., what he eats; she does intervene to an extent to ensure he has a balanced diet, however) to help him develop his own identity. She understands the dominant role mothers play in socializing their children. Her son no longer calls her mummy but by her first name. She now sees that mummy implies dependency. Further, he has asked her to call him by a different name, thereby defining his identity. She takes the time to explain the insensitivity of some sexist statements he sometimes makes to help him become more sensitive. Some of her male colleagues object to her doing this because, in their opinion, it will only make him become more sexist in adulthood. She finds this attitude to be typically arrogant and patriarchal. Specifically, men believe in the definitiveness of male control and its undisputability over time, as though nothing can change maleness as presently defined. In effect they are saying that males cannot be resocialized to be respectful and democratic, thus the struggle for gender equity has no purpose. Men who parent must accept the need to democratize relationships with their children to more fully experience parenting. Women who want to enjoy motherhood more completely should find the challenge of democratizing parent-child relationships to bring about gender sensitivity which is worth the commitment.

The image displays three bands of the reflected visible and infrared wavelength region, with a spatial resolution of 15 m. McCarran International Airport to the south and Nellis Air Force Base to the NE are the two major airports visible. Golf courses appear as bright red areas of worms. The first settlement in Las Vegas (which is Spanish for The Meadows) was recorded back in the early 1850s when the Mormon church, headed by Brigham Young, sent a mission of 30 men to construct a fort and teach agriculture to the Indians. Las Vegas became a city in 1905 when the railroad announced this city was to be a major division point. Prior to legalized gambling in 1931, Las Vegas was developing as an agricultural area. Las Vegas' fame as a resort area became prominent after World War II. The image is located at 36.1 degrees north latitude and 115.1 degrees west longitude.

    NASA Astrophysics Data System (ADS)

    Kemp, Garreth

    2015-02-01

    We focus on the 1/4-BPS sector of free super Yang-Mills theory with an SO(N) gauge group. This theory has an AdS/CFT (an equivalence between a conformal field theory in d-1 dimensions and type II string theory defined on an AdS space in d-dimensions) dual in the form of type IIB string theory with AdS 5 R P 5 geometry. With the aim of studying excited giant graviton dynamics, we construct an orthogonal basis for this sector of the gauge theory in this work. First, we demonstrate that the counting of states, as given by the partition function, and the counting of restricted Schur polynomials match by restricting to a particular class of Young diagram labels. We then give an explicit construction of these gauge invariant operators and evaluate their two-point function exactly. This paves the way to studying the spectral problem of these operators and their D-brane duals.

  19. Mate-sampling costs and sexy sons.

    PubMed

    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.

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

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

    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 changefor instance, higher levels of education, direct exposure to official policy education materials, higher income (a proxy for rural industrialization), and agricultural mechanizationall 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.

    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 mens fathering of their own children, and thus does not explain the association between the fathering young men received and their own fathering behavior. Conclusions Mens 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

    The rate of inflammation increases in elderly individuals, a phenomenon called inflammaging, and is associated with degenerative diseases. However, the causes of inflammaging and the origin of the associated inflammatory mediators have remained enigmatic. We show herein that there is a positive correlation between the number of sons born and C-reactive protein concentrations in 90-year-old women. This association is influenced by HLA genetics known to regulate the immune response against HY antigens. PMID:25721217

    Motivated by the Son-Yamamoto (SY) relation, which connects the three-point and two-point correlators, we consider the holographic renormalization group (RG) flows in the bottom-up approach to holographic QCD via the Hamilton-Jacobi equation with respect to the radial coordinate. It is shown that the SY relation is diagonal with respect to the RG flow in the 5D Yang-Mills-Chern-Simons model, while the RG equation acquires an inhomogeneous term in the model with an additional scalar field, which encodes the chiral condensate.

    Helium behavior in a sodium borosilicate glass (SON68) dedicated to the immobilization of high-level nuclear waste is examined. Two experimental approaches on nonradioactive glass specimens are implemented: pressurized helium infusion experiments and {sup 3}He ion implantation experiments. The temperature variation of helium solubility in SON68 glass was determined and analyzed with the harmonic oscillator model to determine values of the energy of interaction E(0) at the host sites (about -4000 J/mol), the vibration frequency (about 1.7 x 10{sup 11} s{sup -1}), and the density of solubility sites (2.2 x 10{sup 21} sites cm{sup -3}). The implantation experiments show that a non diffusive transport phenomenon (i.e., athermal diffusion) is involved in the material when the helium concentration exceeds 2.3 x 10{sup 21} He cm{sup -3}, and thus probably as soon as it exceeds the density of solubility sites accessible to helium in the glass. We propose that this transport mechanism could be associated with the relaxation of the stress gradient induced by the implanted helium profile, which is favored by the glass damage. Microstructural characterization by TEM and ESEM of glass specimens implanted with high helium concentrations showed a homogeneous microstructure free of bubbles, pores, or cracking at a scale of 10 nm.

  17. The Effect of Parents Attitudes on Sons Marriage Timing

    PubMed Central

    Jennings, Elyse A.; Axinn, William G.; Ghimire, Dirgha J.

    2012-01-01

    Theories of family stability and change, demographic processes, and social psychological influences on behavior all posit that parental attitudes and beliefs are a key influence on their childrens behavior. Though we have evidence of these effects in Western populations, there is little information regarding this social mechanism in non-Western contexts. Furthermore, comparisons of mothers and fathers independent roles in these crucial intergenerational mechanisms are rare. This paper uses measures from a ten-year family panel study featuring independent interviews with both mothers and fathers in rural Nepal to investigate these issues. We test the association of specific attitudes, rather than broad ideational domains, about childbearing and old-age care with sons subsequent marriage behavior. Our results indicate that both mothers and fathers attitudes have important and independent influences on sons marriage behavior. Simultaneous study of both parents attitudes reveals that gender-specific parenting contexts can shape the relationship between parental attitudes and childrens behaviors. This crucial mechanism of intergenerational continuity and change is strong in this non-Western setting, with substantial implications for studies of intergenerational influences on behavior in all settings.

  18. Becoming the Parent of a GLB Son or Daughter

    2014-01-01

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

  19. Food-supplementing parents reduces their sons' song repertoire size.

    PubMed

    Food-supplemented parents typically produce more offspring, as numerous experiments on vertebrate populations have shown. 'Propagule' (egg or neonate) size and parental care may also be affected, with implications concerning the adult quality of offspring, although few experiments have addressed whether food-supplementing one generation affects adult quality in the next. We conducted a food supplementation experiment on song sparrows (Melospiza melodia) and tested whether song repertoire size, a demonstrated indicator of male quality, differed between the adult sons of fed (food-supplemented) and unfed (non-food-supplemented) parents. Counterintuitively, fed parents produced sons with smaller adult song repertoires, who may thus be expected to contribute fewer offspring, and fewer grand-offspring, to the population. Fed and unfed parents invested equally in the total biomass of their clutches and broods, and average nestling condition was comparable, but because fed parents produced more offspring, average egg and nestling sizes were reduced. Fed and unfed parents apportioned care differently within their broods, and we suggest compensatory growth of offspring emerging from light eggs, or egg size itself, may have affected adult repertoire size. Conceivably, the conservation benefits of food-supplementing populations could attenuate over time if fed parents produce offspring of poorer quality than themselves. PMID:19457889

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

    PubMed

    2004-08-01

    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.

    An integrated well log, biostratigraphic, and seismic stratigraphic study of Miocene to Recent deltaic sediments deposited in the Nam Con Son Basin offshore from southern Vietnam shows the influence of eustacy and tectonics on sequence development. Sediments consist of Oligocene non-marine rift-basin fill (Cau Formation), early to middle Miocene tide-dominated delta plain to delta front sediments (TB 1.5 to TB 2.5, Due and Thong Formations), and late Miocene to Recent marine shelf sediments (TB. 2.6 to TB 3.1 0, Mang Cau, Nam Con Son, and Bien Dong Formations). Eustacy controlled the timing of key surfaces and sand distribution in the tectonically-quiet early Miocene. Tectonic effects on middle to late Miocene sequence development consist of thick transgressive systems tracts due to basin-wide subsidence and transgression, sand distribution in the basin center, and carbonate sedimentation on isolated fault blocks within the basin. Third-order sequence boundaries (SB) are identified by spore peaks, sand stacking patterns, and channel incision. In the basin center, widespread shale beds with coal occur above sequence boundaries followed by transgressive sandstone units. These TST sandstones merge toward the basin margin where they lie on older HST sandstones. Maximum flooding surfaces (MFS) have abundant marine microfossils and mangrove pollen, a change in sand stacking pattern, and often a strong seismic reflection with downlap. Fourth-order genetic-type sequences are also interpreted. The MFS is the easiest marker to identify and correlate on well logs. Fourth-order SB occur within these genetic units but are harder to identify and correlate.

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

    Serine-arginine-rich (SR) proteins play a key role in alternative pre-mRNA splicing in eukaryotes. We recently showed that a large SR protein called Son has unique repeat motifs that are essential for maintaining the subnuclear organization of pre-mRNA processing factors in nuclear speckles. Motif analysis of Son highlights putative RNA interaction domains that suggest a direct role for Son in pre-mRNA splicing. Here, we used in situ approaches to show that Son localizes to a reporter minigene transcription site, and that RNAi-mediated Son depletion causes exon skipping on reporter transcripts at this transcription site. A genome-wide exon microarray analysis was performed to identify human transcription and splicing targets of Son. Our data show that Son-regulated splicing encompasses all known types of alternative splicing, the most common being alternative splicing of cassette exons. We confirmed that knockdown of Son leads to exon skipping in pre-mRNAs for chromatin-modifying enzymes, including ADA, HDAC6 and SetD8. This study reports a comprehensive view of human transcription and splicing targets for Son in fundamental cellular pathways such as integrin-mediated cell adhesion, cell cycle regulation, cholesterol biosynthesis, apoptosis and epigenetic regulation of gene expression.

    Antecedentes El esfago de Barrett es una reconocida lesin precursora de adenocarcinoma esofgico. Aunque generalmente asociada al reflujo gastroesofgico, los mecanismos patognicos de la enfermedad no son bien conocidos. El objetivo del presente estudio es explorar la historia natural e identificar marcadores de progreso del proceso precanceroso. Material y mtodos Se utilizaron cortes histolgicos de 67 especmenes de esfago correspondientes a 14 pacientes con esfago de Barrett, a los que se sigui entre 1 9 aos. Se clasificaron las lesiones en: esfago de Barrett sin displasia, indefinido para displasia o con displasia. Se evalu la expresin de diferentes mucinas en las clulas caliciformes y en las columnares usando tcnicas de histoqumica e inmunohistoqumica. Resultados En todos los casos se comprob la presencia de metaplasia intestinal incompleta. Las clulas columnares dentro del epitelio metaplsico contenan mucinas neutras. A mayor severidad de la lesin se encontr significativamente menor expresin de sialomucinas en las clulas columnares (p de tendencia igual a 0,03). En sujetos con lesiones indefinidas para displasia se observ un mayor contenido de sulfomucinas en las clulas caliciformes (p=0,034) y de MUC2 en las clulas columnares (p=0,029) que en sujetos con esfago de Barrett sin displasia. Se observ expresin de la mucina intestinal MUC2 y de la mucina gstrica MUC5AC en todas las muestras. MUC6, una mucina de las glndulas profundas gstricas, se present ocasionalmente.

  7. SON68 glass dissolution driven by magnesium silicate precipitation

    NASA Astrophysics Data System (ADS)

    2013-11-01

    Experimental results are reported on the effect of magnesium silicate precipitation on the mechanisms and rate of borosilicate glass dissolution. Leaching experiments with SON68 glass, a borosilicate containing no Mg, were carried out in initially deionized water at 50 C with a glass-surface-area-to-solution-volume ratio of 20,000 m-1. After 29 days of alteration the experimental conditions were modified by the addition of Mg to trigger the precipitation of Mg-silicate. Additional experiments were conducted to investigate the importance of other parameters such as pH or dissolved silica on the mechanisms of precipitation of Mg-silicates and their consequences on the glass dissolution rate. Mg-silicates precipitate immediately after Mg is added. The amount of altered glass increases with the quantity of added Mg, and is smaller when silicon is added in solution. A time lag is observed between the addition of magnesium and the resumption of glass alteration because silicon is first provided by partial dissolution of the previously formed alteration gel. It is shown that nucleation does not limit Mg-silicate precipitation. A pH above 8 is necessary for the phase to precipitate under the investigated experimental conditions. On the other hand the glass alteration kinetics limits the precipitation if the magnesium is supplied in solution at a non-limiting rate. The concentration of i in solution was analyzed as well as that of boron. The quantity of i released from the glass is estimated with the assumption that i and B are released congruently at the glass dissolution front. The remained quantity of the element i is then supposed to be in the gel or in the secondary phase. In this paper, we do not make a difference between gel and hydrated glass using the same word 'gel' whereas Gin et al. [40] makes this difference. Recent papers [40,41] discussed about different key issues related to the passivation properties of the alteration layer including the hydrated glass layer at the interface with the pristine glass, the gel and the secondary phases. B is not fixed in the gel layer but retention of both B and Li retention is evidenced in one part of the hydrated layer corresponding to a narrow interdiffusion layer [40]. The (H/Li) interdiffusion coefficient decreases by several orders of magnitude when the alteration solution is silica-saturated [41]. This interdiffusion coefficient is a relevant parameter for evaluating the passivation phenomenon. It has also been shown that the nanoporosity of the hydrated glass layer plays an important role [40]. It can be deduced that the precipitation of a silicate secondary phase associated with the consumption of silica strongly affects the hydration rate of the glass and as a consequence its alteration. So the precipitation of secondary phase is a motive force which modifies the physico-chemical properties of the reactive interface situated in the gel or probably in the hydrated glass which has a role of passivation. Currently, the notion of reactive interface and its physico-chemical conditions are under investigations. In our study, solid characterizations are difficult so we use only the general notion of a protective gel. The increased calcium concentrations correspond to congruent dissolution of the gel formed before the addition of magnesium. The Ca/Si molar ratio of the gel was estimated from each experiment based on the data for day 29; in each case the ratio was near 0.1. This hypothesis was not taken into account for the experiment with regular Mg additions because no gel alteration occurred between 45 and 63 days. Glass alteration released boron and silicon in the same proportions as in the glass. No gel formation occurred within the balance period except in the experiment with 100 mg L-1 of Mg at t = 0, for which the cases of 10%, 30% and 50% gel formation (percentage of silicon from glass alteration incorporated in the gel) are indicated as examples. Based on the calcium concentrations in solution for the experiment with 100 mg L-1 of Mg at t = 0, the most representative cas

There is an unusual new feature of Gauss-Bonnet black hole that the avoidance of non-central naked singularity prescribes a mass range for black hole in terms of $\\Lambda>0$. For Einstein-Gauss-Bonnet black hole a limited window of negative values for $\\Lambda$ is also permitted. This topology encompasses black string and brane as well as a generalized Nariai metric.

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

    PubMed Central

    2012-01-01

    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 1317), 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 that agreed the son made the decision. Conclusion Parents and sons play an active role in the decision-making process, with an individuals role being influenced by many factors. The results of this study may be used to guide the messages presented by clinicians when recommending the HPV vaccine, and future vaccine uptake interventions. PMID:23241217

    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 much higher than in BiSON datasets, while a good agreement has been observed during the red period.

    Matricide is one of the rarest of reported murders and has always been considered one of the most abhorrent crimes. Psychiatric investigations as to why a son might murder his mother yield indications of a high rate of mental illness, primarily psychotic disorders, in perpetrators. In an attempt to gain an in-depth understanding of the role of the mother-son bond in the etiology of matricide by mentally disordered sons, this article presents a qualitative study of nine cases of matricide examined at two Italian Forensic Psychiatry Departments between 2005 and 2010 and retrospective analysis of forensic psychiatry reports on the offenders. Most matricides suffered from psychotic disorders, especially schizophrenia. Nevertheless, not all the perpetrators had psychotic symptoms at the time of the crime. A "pathologic" mother-son bond was found in all cases. However, mental illness is not the only variable related to matricide and, taken alone, is not enough to explain the crime. Several factors in the history of the mother and son need to be probed, especially how their relationship developed over the years. The peculiar dynamics of the mother-son relationship and the unique personalities and life experiences of both subjects are the real key to cases of matricide. PMID:25100768

  4. Individual mares bias investment in sons and daughters in relation to their condition.

    PubMed

    Cameron; Linklater

    2000-09-01

    The Trivers-Willard hypothesis (TWH) predicts that a mother will treat a son or daughter differently depending on her ability to invest and the impact of her investment on offspring reproductive success. Although many studies have investigated the hypothesis, few have definitively supported or refuted it because of confounding factors or an inappropriate level of analysis. We studied maternal investment in sons and daughters in feral horses, Equus caballus, which meet the assumptions of the TWH with a minimum of confounding variables. Population level analyses revealed no differences in maternal behaviour towards sons and daughters. When we incorporated mare condition, we found that sons were more costly to mares in good condition, whereas daughters were more costly to mares in poor condition, although no differences in maternal behaviour were found. However, since the TWH makes predictions about individual mothers, we examined investment by mares who reared both a son and a daughter in different years of the study. Mares in good condition invested more in their sons in terms of maternal care patterns, costs to maternal body condition and costs to future reproduction. Conversely, mares in poor condition invested more in daughters. Therefore, with an appropriate level of analysis in a species in which confounding variables are minimal, the predictions of the Trivers-Willard hypothesis are supported.

  5. History: Las Vegas

    NSDL National Science Digital Library

    Las Vegas (or "The Meadows" in Spanish) is a curious place, and it is not much of a stretch to say that it was transformed from a sleepy railroad town into a ring-a-ding swinging town in just a few decades during the 20th century. The Las Vegas Sun has gone above and beyond the call of duty by crafting a site that presents a multimedia-rich experience that narrates the history of this rather unique American city. Visitors should start their journey here by watching one or all eleven parts of their "Boomtown" video on the history of the town. Then visitors may want to take a look at the interactive map of the "Strip", which tells the fortunes of casinos and other buildings, past, present, and future, which have graced this notable region of mega-structures amidst the desert. After that, visitors should look at the "12 Voices from the Past" area. Voices like casino owner Benny Binion and former Nevada governor Mike O'Callaghan are featured here, and it's a great trip back through the city's varied past.

    This study examines the ways single Black mothers contribute to the educational success of their 11th-grade sons, despite the fact that their sons are enrolled in "failing schools." Data from five interviews and one focus group reveal common characteristics of how single-Black mothers help their sons beat the odds.

  11. Parental involvement with adolescents' education: do daughters or sons get more help?

    2000-01-01

    This research examined whether parents were involved differently with the education of their adolescent daughters and sons. The investigation used data from the National Education Longitudinal Study (NELS), which collected information from approximately 25,000 eighth-grade students. Several types of parental involvement were analyzed for gender differences, including school discussion, parent-school connection, parental expectations, parental attendance at school events, and three measures of parental supervision (checking homework, limiting television watching, and limiting going out with friends). The results showed that, net of students' grades, tests scores, and educational aspirations, parents helped daughters in some ways and sons in other ways. Generally, daughters experienced more parental involvement with their education than did sons. The findings are discussed in terms of parents' traditional socialization practices versus a shift in parental treatment in response to social trends. PMID:10841295

  12. DO SONS OR DAUGHTERS GIVE MORE MONEY TO PARENTS IN URBAN CHINA?*

    The patriarchal structure of the traditional Chinese family suggests that sons, more than daughters, provide financial support to elderly parents. The norm of receiving support in old age primarily from sons, however, may have been undermined by dramatic demographic, economic, and cultural changes occurring over the last several decades in China, especially in urban areas. We examine gender differences in adult childrens financial support to parents using a recent dataset (Study of Family Life in Urban China") collected in 1999 (N = 1,801). The results show that married daughters, especially those living with parents, provide more financial support to parents than married sons do. This significant gender difference can be primarily explained by daughters resources, such as education and income. PMID:20126304

    Investigation of the climatic and environmental impacts of the Youngest Toba Tuff (YTT, 74 ka BP) eruption of Toba volcano, Sumatra, is crucial for understanding the consequences of the eruption for contemporaneous human populations. The Middle Son Valley, in India, was the first locality on the Indian subcontinent where the YTT was reported. The ash bed forms a discontinuous layer stretching for over 30 km along the river. Here we report on the stratigraphic contexts of YTT ash layers in alluvial deposits of the Middle Son Valley, in order to reconstruct the taphonomy of the ash deposits and the dynamic of their deposition. Although the distal ash has been studied since the 1980s, its stratigraphic integrity and the mechanisms and pathways involved in its transport and deposition have bit previously been assessed. We find that the YTT occurrences in the Middle Son Valley may not be reliable chronostratigraphical markers for millennial scale palaeoenvironmental reconstruction.

    This study asks parents who have children with Down syndrome 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 Down syndrome 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 Down syndrome have good relationships with their siblings with Down syndrome. The overwhelming majority of parents surveyed report that they are happy with their decision to have their child with Down syndrome and indicate that their sons and daughters are great sources of love and pride.

    Purpose The quadrivalent HPV vaccination was approved for use in males ages 9 to 26 in 2009 and recommended for routine administration in 2011. The purpose of this study was to uncover predictable commonalities amongst parents who chose to vaccinate their 1117 year old sons against HPV. Methods We compiled data from a U.S. national sample of 779 parents with sons 1117 years old using a web-based survey to gather information about behavioral and sociodemographic factors which predicted receipt of 1 or more HPV vaccine doses based on parental report. Predictors were first modeled individually for univariable associations. Significant predictors (p<0.10) were combined in a multivariable model. Results In the adjusted model, independent predictors included receipt of flu vaccination, health insurance coverage and sexual health topic discussions with sons. Sons who had received a flu shot in the last two years more frequently received at least one dose of the vaccine (OR 1.82; 95% CI 1.452.26). Sons covered by private health insurance had decreased odds of HPV vaccination (OR 0.56 95% CI 0.370.83). Lastly, parents who had discussed sexual health topics with their sons were more likely to vaccinate (OR 1.61; 95% CI 1.371.89). Conclusions Male vaccination rates in the U.S. have increased, but males continue to be under-immunized. Utilization of health care is an important factor in HPV vaccine uptake; therefore, health care providers should use every contact as an opportunity to vaccinate. Communication about sexual health topics may provide a forum for parents and health care providers to have conversations about HPV vaccination as those more comfortable discussing these topics may also be more comfortable discussing HPV vaccination.

    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. PMID:23965259

    Mother-son mating (oedipal mating) is practically non-existent in social Hymenoptera, as queens typically avoid inbreeding, mate only early in life and do not mate again after having begun to lay eggs. In the ant genus Cardiocondyla mating occurs among sib in the natal nests. Sex ratios are extremely female-biased and young queens face the risk of remaining without mating partners. Here, we show that virgin queens of Cardiocondyla argyrotricha produce sons from their own unfertilized eggs and later mate with them to produce female offspring from fertilized eggs. Oedipal mating may allow C. argyrotricha queens to found new colonies when no mating partners are available and thus maintains their unusual life history combining monogyny, mating in the nest, and low male production. Our result indicates that a trait that sporadically occurs in solitary haplodiploid animals may evolve also in social Hymenoptera under appropriate ecological and social conditions.

    Objectives The aim of this prospective study was to investigate whether occupational pesticide exposure during pregnancy causes adverse effects on the reproductive development in the male infants. Design and measurements Pregnant women employed in greenhouses in Denmark were consecutively recruited, and 113 motherson pairs were included. The mothers were categorized as occupationally exposed (91 sons) or unexposed (22 sons) to pesticides during pregnancy. Testicular position and volume, penile length, and position of urethral opening were determined at 3 months of age using standardized techniques. Concentrations of reproductive hormones in serum from the boys were analyzed. Results The prevalence of cryptorchidism at 3 months of age was 6.2% [95% confidence interval (CI), 3.012.4]. This prevalence was considerably higher than among Danish boys born in the Copenhagen area (1.9%; 95% CI, 1.23.0) examined by the same procedure. Boys of pesticide-exposed mothers showed decreased penile length, testicular volume, serum concentrations of testosterone, and inhibin B. Serum concentrations of sex hormone-binding globulin, follicle-stimulating hormone, and the luteinizing hormone:testosterone ratio were increased compared with boys of nonexposed mothers. For individual parameters, only the decreased penile length was statistically significant (p = 0.04). However, all observed effects were in the anticipated direction, and a joint multivariate test showed that this finding had a p-value of 0.012. Conclusions Our findings suggest an adverse effect of maternal occupational pesticide exposure on reproductive development in the sons despite current greenhouse safeguards and special measures to protect pregnant women.

    2013-01-01

    We use a nationally representative survey of Indian households (NFHS-3) to conduct the first study that analyzes whether son preference is associated with girls bearing a larger burden of housework than boys. Housework is a non-negligible part of child labor in which around 60 % of children in our sample are engaged. The preference for male offspring is measured by a mothers ideal proportion of sons among her offspring. We show that when the ideal proportion increases from 0 to 1, the gap in the time spent on weekly housework for an average girl compared to that of a boy increases by 2.5 h. We conduct several robustness analyses. First, we estimate the main model separately by caste, religion, and family size. Second, we use a two-stage model to look at participation into housework (as well as other types of work) in addition to hours. Third, we use mothers fertility intentions as an alternative measure of son preference. The analysis confirms that stated differences in male preference translate in de facto differences in girls treatment. PMID:23914000

    Life history theory predicts that mothers should provide their offspring with a privileged upbringing if this enhances their offspring's and their own fitness. In many mammals, high-ranking mothers provide their offspring with a privileged upbringing. Whether dispersing sons gain fitness benefits during adulthood from such privileges (a 'silver spoon' effect) has rarely been examined. In this paper, we show that in the complex, female-dominated society of spotted hyaenas, high-born sons grew at higher rates, were more likely to disperse to clans offering the best fitness prospects, started reproducing earlier and had a higher reproductive value than did lower-born sons. This illustrates the evolutionary importance of maternal effects even in societies in which male size or fighting ability does not influence fitness. By demonstrating for the first time in a non-human mammal that maternal status influences immigration patterns, the study also advances our understanding of two key ecological and evolutionary processes, dispersal and habitat selection.

  8. Men as caregivers of the elderly: support for the contributions of sons

    2014-01-01

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

    Recent exploration of the south east Nam Con Son Basin, offshore Vietnam, by BP in alliance with Statoil has involved acquisition of new seismic and well data. These new data have allowed re-evaluation of the tectono-stratigraphic development and petroleum geology, and have provided additional constraints on the regional tectonic evolution. The offshore Vietnamese basins have evolved in response to the complex relative motions of Indochina, Peninsular Malaysia, Borneo and the South China Sea during the Cenozoic. On the regional scale these motions have been accommodated by strike-slip fault development, rifting and contraction. In the Nam Con Son Basin these motions have interacted in different ways from the Palaeogene to recent. Two rifting episodes are recognized; a Palaeogene phase dominated by E-W trending extensional faults, and a Miocene phase dominated by N-S to NE-SW trending faults. The structural evolution is complicated by a pulse of mild contraction during the Middle Miocene. The sedimentary fill of the basin evolves from continental fluvio-lacustrine in the Palaeogene through to fully marine following the second phase of rifting in the Miocene. This pulsed structural and stratigraphic evolution has resulted in basinwide deposition of source, reservoir and seal facies, and produced a variety of potential trapping styles. This paper describes the hydrocarbon habitat of the south east Nam Con Son Basin within the context of the regional tectono-stratigraphic model.

    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. PMID:25425060

    In many mammals, early social experience is critical to developing species-appropriate adult behaviors. Although mother-infant interactions play an undeniably significant role in social development, other individuals in the social milieu may also influence infant outcomes. Additionally, the social skills necessary for adult success may differ between the sexes. In chimpanzees (Pan troglodytes), adult males are more gregarious than females and rely on a suite of competitive and cooperative relationships to obtain access to females. In fission-fusion species, including humans and chimpanzees, subgroup composition is labile and individuals can vary the number of individuals with whom they associate. Thus, mothers in these species have a variety of social options. In this study, we investigated whether wild chimpanzee maternal subgrouping patterns differed based on infant sex. Our results show that mothers of sons were more gregarious than mothers of daughters; differences were especially pronounced during the first 6 mo of life, when infant behavior is unlikely to influence maternal subgrouping. Furthermore, mothers with sons spent significantly more time in parties containing males during the first 6 mo. These early differences foreshadow the well-documented sex differences in adult social behavior, and maternal gregariousness may provide sons with important observational learning experiences and social exposure early in life. The presence of these patterns in chimpanzees raises questions concerning the evolutionary history of differential social exposure and its role in shaping sex-typical behavior in humans.

    This study focuses on the mother-son relationship of 13 mothers caring for single sons between the ages of 15 and 30 years who have higher brain dysfunction due to a traumatic brain injury. We aimed to elucidate the psychosocial adjustment process of mothers for 5 years following the injury to facilitate the social rehabilitation of both mother and son. Data obtained through a semistructured interview method were analyzed using a modified grounded theory approach. After 56 concepts were identified, 18 categories and then 8 core categories were semantically created. The 8 core categories were (a) avoid contact with son, (b) support son based on mother's own desire, (c) support son alone without external support, (d) realize mother's care limits and seek external support sources, (e) request and utilize external support, (f) support and work toward son's independence while monitoring his interactions with others, (g) mother considers own feelings and reenters society, and (h) strive for continued care of son with mother's acquired energy and efficient management skills. These were grouped into the following five stages: (a) avoidance, (b-c) closed, (d) support seeking, (e-f) withdrawal, and (g-h) reconstruction. PMID:19835241

  6. Glacial and proglacial Talchir sedimentation in Son-Mahanadi Gondwana basin: Paleogeographic reconstruction

    NASA Astrophysics Data System (ADS)

    Casshyap, S. M.; Srivastava, V. K.

    In the southern part of the Son-Mahanadi basin, the early Permian glacigene Talchir rocks occur in exhumed glacial valleys overlying the Precambrian basement unconformably with gentle to somewhat steeper contacts. In the broader low lying part to the north, the strata are flat lying and uninterrupted by granitic inliers. The overall sequence thickens progressively lengthwise from south (400 m) to north (800 m) and from the margins of the basin inward. Two distinct groups of facies characterize the Talchir assemblage. The first group, the proximal facies, occurs in exhumed valleys near the granitic highlands and includes diamictite, conglomerate, and sandstone. The second group, distal facies, occurs away from the highlands in the broader, northern region and abounds in fine elastics. This group includes shale and rhythmites containing dropstones. Paleocurrent analysis suggests that the ice movement and paleoflow of meltwater streams were directed locally inward and regionally along the length of the basin from southeast to northwest. The occurrence of marine fauna at Manendragarh and Umaria is the only evidence of marine ingression along the northwestern margin. However, there is no conclusive evidence of marine transgression to the south of Manendragarh. The present study suggests a somewhat plateau-like upland topography in the southern part of the Mahanadi basin, with a dissected northern edge passing into an extensive low-lying Son basin farther north. The entire southern terrain was characterized by the exhumed valleys dominated by glacial, glaciofluvial, and glaciolacustrine environments, whereas the low lying northern terrain represented deltaic milieu in the central part and tidal estuary setting along the margins of the basin in the northwest. The paper reconstructs the paleogeography of the Son-Mahanadi basin during early Permian time.

    The perception of elder financial exploitation was investigated using community members (N = 104) and undergraduates (N = 143). Participants read an exploitation trial summary; an 85-year-old victim accused her son of stealing her money. Primary results indicated that alleged victims described as healthy rendered more guilty verdicts than those described as having a cognitive deficit; pro-victim judgments were higher for women than men; and younger and older community members' rendered more guilty verdicts than middle-aged mock jurors. The results are discussed in terms of the factors that impact the perception of exploitation in court. PMID:23473296

    Helle, Samuli; Lummaa, Virpi

    2013-01-01

    A bias in reproduction towards sons, which are energetically more costly than daughters, has been suggested to shorten parental lifespan, but previous results have been mixed. Reproductive costs should be most evident in low rather than high resource settings, and are not expected to be severe in men, because women pay higher direct costs of reproduction. We, therefore, used demographic data from pre-industrial Finland to investigate whether the number of sons and daughters born affected their parents post-reproductive survival and whether this was related to parent's resource availability. Irrespective of access to resources, mothers, but not fathers, with many sons suffered from reduced post-reproductive survival, and this association decreased as mothers aged. Our results provide evidence that Finnish mothers traded long post-reproductive lifespan for giving birth to many sons. PMID:23445948

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

    We analyzed BiSON and GOLF/SoHO data with a new technique, to investigate p-mode power variation over solar cycle 23. We found a decrease in the mean velocity power of about 20% for BiSON during the ascending phase, in agreement with previous findings. We also found that GOLF, during the red-wing configuration, seems to be working at a different height than the theoretically computed one.

    Retrospective reports of children's relationships with their parents have been associated with increased risk for depressive symptoms in adulthood. This study examined four dimensions of the current mother-child relationship (affection, criticism, over-involvement, conflict) in relation to depressive symptoms in a sample of 270 HIV-positive men who have sex with men (MSM). Depressive symptoms were positively associated with overt conflict or disagreement with mothers and perceived over-involvement by mothers, and inversely related to frequency of contact with mothers. These findings suggest that clinicians who treat HIV-positive methamphetamine-using MSM with depressive symptoms should evaluate issues in the mother-son relationship and consider family-based therapies as an adjunct to treatment.

    Members of the American Association on Mental Retardation (AAMR) Social Work Division (N = 395) were surveyed to determine their perceptions of their role in assisting older parents in permanency planning. Practitioners, administrators, and educators similarly perceived ease in counseling aging families, but also noted their need for additional resources and specialized training. Written comments revealed (a) that the system must do more; (b) older parents are seen as different from other parents, with practitioners concerned about dependency in these parents' relationships with their sons and daughters and administrators attributing differences to past adverse system interactions; (c) parents old and young are alike in many ways; and (d) siblings should be involved in family caregiving. Recommendations were made with regard to meeting the special needs of older families, reducing "blaming" attitudes among social workers, and expanding best practice knowledge. PMID:7623672

    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. PMID:18660478

    Introduction The task of the caregiver, especially a caregiving mother of a son with a chronic and fatal disease, may interfere with their quality of sleep, sexuality, and some hormone levels. Aim The aim of this study was to evaluate the sexual function and the quality of sleep of caregiving mothers of sons with Duchenne muscular dystrophy (DMD). Methods We evaluated 20 caregiving mothers of sons with DMD and 20 caregiving mothers of sons without any neuromuscular or chronic disease. All of them voluntarily responded to the evaluating questionnaires about their sexuality and their quality of sleep, and gave blood samples to evaluate their hormonal levels. Main Outcome Measures All mothers were evaluated using the questionnaire of Female Sexual Function Index (FSFI) and the Pittsburgh questionnaire (PSQI). The blood samples were tested to determine serum levels of testosterone, estradiol, follicle-stimulating hormone, luteinizing hormone, progesterone, adrenocorticotropic hormone, and cortisol. Results Caregiving mothers of sons with DMD had significantly lower scores in the FSFI questionnaire, suggesting a higher risk for sexual dysfunction. The PSQI demonstrated that these caregiving mothers present increased sleep latency, reduced sleep efficiency, daytime dysfunction, and poor sleep quality. Blood tests showed a rise in cortisol levels, which correlated with the compromised sexuality and quality of sleep. Conclusions This study indicates that caregiving mothers of sons with DMD show major risk for sexual dysfunction and a reduction in their quality of sleep mediated in part by the hormonal changes related to stress.

    Maternal behaviour has profound, long-lasting implications for the health and well-being of developing offspring. In the monogamous California mouse (Peromyscus californicus), care by both parents is critical for offspring survival. We tested the hypothesis that similar to maternal care in rodents, paternal huddling and grooming (HG) behaviour can be transmitted to future generations via behavioural mechanisms. In California mice, testosterone maintains paternal HG behaviour. In the present study, we randomly assigned a group of male California mice to castration or sham-operated conditions and allowed them to raise their offspring normally. Adult sons of these males were paired with a female, and they were observed interacting with their own offspring. We found that like their fathers, the sons of castrated males huddled and groomed their young at lower levels than the sons of sham-operated fathers. The sons of castrates also retrieved pups more frequently. When both parents were present, the sons of castrates also showed a trend towards engaging in less exploratory behaviour. These data support the hypothesis that paternal behaviour, like maternal behaviour, can be transferred to future generations via epigenetic mechanisms and suggest that in a biparental species both parents contribute to offspring behavioural development.

    Given that girls show more interpersonal concern than boys, it was predicted that more mother-daughter than mother-son dyads would develop a relationship of mutual concerned responsiveness (CR). Two hundred and twenty-six Israeli children (7-8 years old) and 91 mother-child pairs provided narratives of mother-child interactions. At high levels of socioeconomic status (SES), descriptions of child but not maternal concern differed by gender; therefore, more mother-daughter narratives described mutual CR and more mother-son narratives described a nonreciprocal pattern of maternal CR. In a low-SES sample, most mother-daughter narratives described mutual CR, but many mothers and sons described little concern by either partner. Results provided clear evidence of gender differences in mother-child reciprocity and confirmed the importance of examining gender influences in different social groups. PMID:18717893

    This article explores the persistence of son preference in a patrilineal, patrilocal society in the midst of fertility decline. Using survey and ethnographic data from Hindu-caste Nepali families in a semiurban village, I analyze which cultural norms regarding reproduction are questioned by contemporary married couples and which remain intact. Despite modest improvements in gender equality, levels of education, and economic conditions, the practical knowledge that daughters will be lost to other lineages and households pressures couples who might otherwise be willing to invest in daughters to continue procreating until they produce a son. Young mothers, therefore, reluctantly admit to needing a son, revealing a discrepancy between their initially stated reproductive ideals and their ultimate behavior. PMID:21466108

  9. The Harmonic Convergence of Fathers Predicts the Mating Success of Sons in Aedes aegypti

    During courtship males often communicate information about their fitness to females. The matching of harmonic components of flight tone in male-female pairs of flying mosquitoes, or harmonic convergence, was recently described. This behaviour occurs prior to mating and has been suggested to function in mate selection. We investigated the hypothesis that harmonic convergence is a component of mosquito courtship. A key prediction of this hypothesis is that harmonic convergence should provide information to potential mates about fitness benefits. We measured the effect of harmonic convergence behaviour on the direct and indirect benefits obtained by females. We found that the sons of pairs that converged at harmonic frequencies prior to mating had increased mating success and that these offspring were themselves more likely to converge prior to mating. These results suggest that males may be able to signal information about their genetic quality to females prior to mating and that this signal may be heritable. These findings are important for our understanding of mosquito behaviour and have applications in the control of mosquito-borne disease. This study also contributes to the study of male-female interactions and signal coevolution. PMID:22003255

    2002-01-01

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

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

    Cardiofaciocutaneous (CFC) syndrome is a rare genetic disorder belonging to the group of RASopathies. It is typically characterized by congenital heart defects, short stature, dysmorphic craniofacial features, intellectual disability, failure to thrive, and ectodermal abnormalities such as hyperkeratosis and sparse, brittle, curly hair. CFC syndrome is caused by dominant mutations in one of the four genes BRAF, MEK1, MEK2, and KRAS. Only three familial cases of CFC syndrome have been reported to date, whereas the vast majorities are sporadic cases due to de novo mutations. We report on a fourth familial case with transmission of CFC syndrome from father to son due to a novel heterozygous sequence change c.376A>G (p.N126D) in exon 3 of MEK2 gene. This observation further documents the possibility of vertical transmission of CFC syndrome, which appears to be associated with rare mutations and relatively mild intellectual disability in affected individual. The hypomorphic effect of specific mutations particularly regarding neurocognitive issues may be related to the variable fertility of affected individuals. PMID:25487361

    Permo-Triassic intermediate-felsic magmatism is developed along the Truong Son fold belt, located in the eastern margin of the Indochina Block. It comprises a succession of the active continental margin associations: calc-alkaline volcano-plutonic associations (272-248 Ma), peraluminous granites (259-245 Ma), and subalkaline felsic volcano-plutonic associations (younger than 245 Ma). Detailed study of geochemical characteristics such as trace elements (LILE, REE, HFSE) and isotopes (Sr, Nd, Pb) indicates that they are homogeneous and that they are products of the Palaeotethys subduction process in relation to Indochina (IC)/North Vietnam-South China (NV-SC) amalgamation (S.L. Chung et al., Abstr., GEOSEA 98, Malaysia, 1998, pp. 17-19). The Indosinian characteristics are represented by mantle-crust interaction in magma generation, controlled by their emplacement localities in relation to the Kontum Uplift. The spatial and temporal evolution of Permo-Triassic magmatism allows reconstructing the geodynamic history of the Indosinian orogeny. It confirms that this event ended in Early to Middle Triassic (246-240 Ma, after C. Lepvrier et al., Tectonophysics 393 (2004) 87-118).

  14. Successful sons or superior daughters: sex-ratio variation in springbok

    2005-01-01

    Mothers would often benefit from producing more offspring of one sex than the other. Although some species show an astonishing ability to skew their sex ratio adaptively, the trends found in many studies on vertebrates have proved inconsistent. Furthermore, evidence for a mechanism by which such a bias is achieved is equivocal at best. Here, we examine sex-ratio variation over 30 years, both at an individual and a population level, in the highly polygynous, size-dimorphic springbok (Antidorcas marsupialis). Many previous studies of similar species have shown that mothers in superior condition preferentially produce sons, whereas those in poorer condition produce more daughters. We found the opposite to be true in springbok, perhaps because daughters provide mothers in superior condition with a more rapid and secure fitness return. This theory was supported by the findings that earlier-conceived offspring tended to be female and that an increased proportion of daughters were produced with increasing rainfall (which was likely to reduce nutritional stress). We also show that selective reabsorption of embryos is unlikely to be the main mechanism by which deviations from an equal sex ratio are achieved. Hence, either differential implantation occurs or females are able to influence the sex of the sperm fertilizing an egg. PMID:15734691

    Receptor tyrosine kinases participate in several signaling pathways through small G proteins such as Ras (rat sarcoma). An important component in the activation of these G proteins is Son of sevenless (SOS), which catalyzes the nucleotide exchange on Ras. For optimal activity, a second Ras molecule acts as an allosteric activator by binding to a second Ras-binding site within SOS. This allosteric Ras-binding site is blocked by autoinhibitory domains of SOS. We have reported recently that Ras activation also requires the actin-binding proteins ezrin, radixin, and moesin. Here we report the mechanism by which ezrin modulates SOS activity and thereby Ras activation. Active ezrin enhances Ras/MAPK signaling and interacts with both SOS and Ras in vivo and in vitro. Moreover, in vitro kinetic assays with recombinant proteins show that ezrin also is important for the activity of SOS itself. Ezrin interacts with GDP-Ras and with the Dbl homology (DH)/pleckstrin homology (PH) domains of SOS, bringing GDP-Ras to the proximity of the allosteric site of SOS. These actions of ezrin are antagonized by the neurofibromatosis type 2 tumor-suppressor protein merlin. We propose an additional essential step in SOS/Ras control that is relevant for human cancer as well as all physiological processes involving Ras. PMID:24297905

    According to the 1990 Census, 13,700,000 children are living in female headed, single parent homes. This situation raises the question of how the involved youngsters are affected. Specifically, one might wonder about the effects of the father's absence on boys. Traditionally, the presence of the father has been considered necessary for the adequate psychological development of his son. Many researchers

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

    PubMed

    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.

    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.

    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 childrens future educational attainment, perceptions of their childrens 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.

  2. An X-Linked Sex Ratio Distorter in Drosophila simulans That Kills or Incapacitates Both Noncarrier Sperm and Sons

    2014-01-01

    Genomic conflict occurs when a genomic component gains a reproductive advantage at the expense of the organism as a whole. X-linked segregation distorters kill or incapacitate Y-bearing sperm, thereby gaining a transmission advantage but also reducing male fertility and generating a female-biased sex ratio. When some damaged, Y-bearing sperm survive and fertilize eggs, then the segregation distortion phenotype could be expanded by harming or killing sons in the next generation. X-linked son-killers are predicted by theory to be favored by natural selection and evolve when brothers and sisters compete for shared limiting resources and/or when brothers reduce the inclusive fitness of their sisters via sib-matinga phenomenon called SA-zygotic drive. Here I develop and use a process-of-elimination screen to show that an unclassified X-linked sex ratio distorter (skew) in Drosophila simulans kills or incapacitates noncarrier sperm and also kills a substantial proportion of sons, i.e., it has both a segregation distortion and a SA-zygotic drive phenotype. There are three unique X-linked segregation distorters known to occur in D. simulans named Winters, Durham, and Paris. Autosomal-dominant suppressors of Winters (Nmy) and Durham (Tmy) failed to suppress skew. A Y-linked suppressor of Paris, however, did suppress skew, and a recombination test failed to detect recombinants between these two sex ratio distorters, indicating that they are tightly linked and plausibly identical or allelic. Son-killing may be an important yet unrecognized component of other X-linked segregation distorters. PMID:25081980

    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 partners side and favour the social organization of the

    SON is a DNA- and RNA-binding protein localized in nuclear speckles. Although its function in RNA splicing for effective cell cycle progression and genome stability was recently unveiled, other mechanisms of SON functions remain unexplored. Here, we report that SON regulates GATA-2, a key transcription factor involved in hematopoietic stem cell maintenance and differentiation. SON is highly expressed in undifferentiated hematopoietic stem/progenitor cells and leukemic blasts. SON knockdown leads to significant depletion of GATA-2 protein with marginal down-regulation of GATA-2 mRNA. We show that miR-27a is up-regulated upon SON knockdown and targets the 3?-UTR of GATA-2 mRNA in hematopoietic cells. Up-regulation of miR-27a was due to activation of the promoter of the miR-23a?27a?24-2 cluster, suggesting that SON suppresses this promoter to lower the microRNAs from this cluster. Our data revealed a previously unidentified role of SON in microRNA production via regulating the transcription process, thereby modulating GATA-2 at the protein level during hematopoietic differentiation.

  15. Mothers, fathers, sons, and daughters: gender differences in factors associated with parent-child communication about sexual topics

    PubMed Central

    2010-01-01

    Background In the United States, nearly half of high school students are sexually active, and adolescents experience high rates of unintended pregnancy and sexually transmitted diseases. Parents can have an important influence on their children's sexual behaviour, but many parents do not talk with their children about sexual topics. Research has shown significant differences in parent-child communication about sexual topics depending on the gender of both the parent and the child. Little is known, however, about the reasons for these gender differences. The purpose of this paper is to describe how factors associated with parent-child communication about sexual topics differ by gender. Methods Data are from a nationwide online survey with 829 fathers and 1,113 mothers of children aged 10 to 14. For each of the four gender groups (fathers of sons, fathers of daughters, mothers of sons, mothers of daughters), we calculated the distribution of responses to questions assessing (1) parent-child communication about sex-related topics, and (2) factors associated with that communication. We used chi-square tests to determine whether the distributions differed and the false discovery rate control to reduce the likelihood of type I errors. Results With both sons and daughters, fathers communicated less about sexual topics than mothers did. Fathers also had lower levels of many characteristics that facilitate communication about sex (e.g., lower self-efficacy and lower expectations that talking to their children about sex would have positive outcomes). Compared with parents of sons, parents of daughters (both mothers and fathers) talked more about sexual topics, were more concerned about potential harmful consequences of sexual activity, and were more disapproving of their child having sex at an early age. Conclusions Using a large national sample, this study confirms findings from previous studies showing gender differences in parent-child communication about sexual topics and identifies gender differences in factors that may influence parent-child communication about sexual topics. Interventions designed to support parent-child communication about sexual topics should emphasize to both mothers and fathers the importance of talking to sons as well as daughters. Fathers need particular support to overcome the barriers to communication they encounter. PMID:21156057

    This study examines the relationship between the husband's preference for a son, sex composition of children and risk of anaemia and underweight among married Indian women. Information was collected regarding 29,517 couples having at least one child in the nationally representative 2005-06 National Family Health Survey of India. The exposures were husband's preference for a son and sex composition of children: sons only, daughters only and mixed. Outcome included maternal underweight and moderate/severe anaemia. Husband's preference for a son was not found to be associated with his wife's risk of anaemia or underweight. Sex composition of the children was modestly associated with increased odds of anaemia among women from households with daughters only as compared with those with sons only [AOR: 1.19; 95% CI 1.04, 1.35]. The findings from this population-based study of socio-cultural norms around preference for a son and married Indian women's nutritional status do not support the hypothesis that husband's preference for sons influences the nutritional status of their wives. However, having daughters only is associated with maternal anaemia for reasons that remain to be established. PMID:22150711

  18. Devonian fish (Placodermi, Antiarcha) from Tra Ban Island (Bai Tu Long Bay, Quang Ninh Province, Vietnam) and the question of the age of the D Son Formation

    Remains of an Asterolepis-like antiarchan placoderm fish are reported from the top part of the sandstone series of the Tra Ban Island (Quang Ninh Province, Vietnam), which are referred to the D Son Formation. This sandstone series is overlain by the well-dated Late Givetian-Frasnian Trang Kenh Formation, which constrains the top part of the D Son Formation to the Middle Devonian, and most probably the Givetian, as suggested by the presence of a large Asterolepis-like antiarch. This would agree with the fish and plant assemblage previously recorded from the upper part of the D Son Formation at D Son. The question of the age of the base of the D Son Formation is raised by the discovery of Late Silurian or Early Lochkovian plant, arthropod and fish remains at D Son. The D Son Formation now appears to be composed of two members, Late Silurian (or Early Lochkovian) and Givetian in age, respectively. Recent field observations suggest that the two members are separated by an unconformity. The meaning of the Devonian terrigenous deposits in the eastern part of Vietnam and south China is briefly discussed.

  20. Distinct synaptic mechanisms create parallel S-ON and S-OFF color opponent pathways in the primate retina

    Anatomical and physiological approaches are beginning to reveal the synaptic origins of parallel ON- and OFF-pathway retinal circuits for the transmission of short (S-) wavelength sensitive cone signals in the primate retina. Anatomical data suggest that synaptic output from S-cones is largely segregated; central elements of synaptic triads arise almost exclusively from the blue-cone bipolar cell, a presumed ON bipolar, whereas triad-associated contacts derive primarily from the flat midget bipolar cell, a hyperpolarizing, OFF bipolar. Similarly, horizontal cell connectivity is also segregated, with only the H2 cell-type receiving numerous contacts from S-cones. Negative feedback from long (L-) and middle (M-) wavelength sensitive cones via the H2 horizontal cells elicits an antagonistic surround in S-cones demonstrating that S versus L + M or blue-yellow opponency is first established in the S-cone. However, the S-cone output utilizes distinct synaptic mechanisms to create color opponency at the ganglion cell level. The blue-cone bipolar cell is presynaptic to the small bistratified, blue-ON ganglion cell. S versus L + M cone opponency arises postsynaptically by converging S-ON and LM-OFF excitatory bipolar inputs to the ganglion cells bistratified dendritic tree. The common L + M cone surrounds of the parallel S-ON and LM-OFF cone bipolar inputs appear to cancel resulting in blue-yellow antagonism without center-surround spatial opponency. By contrast, in midget ganglion cells, opponency arises by the differential weighting of cone inputs to the receptive field center versus surround. In the macula, the private-line connection from a midget ganglion cell to a single cone predicts that S versus L + M opponency is transmitted from the S-cone to the S-OFF midget bipolar and ganglion cell. Beyond the macula, OFF-midget ganglion cell dendritic trees enlarge and collect additional input from multiple L and M cones. Thus S-OFF opponency via the midget pathway would be expected to become more complex in the near retinal periphery as L and/or M and S cone inputs sum to the receptive field center. An important goal for further investigation will be to explore the hypothesis that distinct bistratified S-ON versus midget S-OFF retinal circuits are the substrates for human psychophysical detection mechanisms attributed to S-ON versus S-OFF perceptual channels.

  6. Self-regulation in early adolescence: relations with mother-son relationship quality and maternal regulatory support and antagonism.

    2010-11-01

    The purpose of the current investigation was to examine relations among maternal regulatory support, maternal antagonism, and mother-son relationship quality in relation to boys' self-regulation during early adolescence. As part of a larger longitudinal study on 263 low-income, ethnically diverse boys, multiple informants and methods were used to examine associations among parenting practices and mother-son relationship quality in relation to boys' self-regulation at ages 10 and 11. Multivariate analyses indicated that high levels of regulatory supportive parenting and relationship quality and low levels of antagonistic parenting independently predicted high levels of boys' self-regulation at age 10. Only antagonistic parenting and relationship quality explained variance in levels of boys' self-regulation at age 11 after accounting for prior self-regulation. The findings suggest that parenting and the context of the parent-child relationship are linked to self-regulation during early adolescence; however, it appears that parental antagonism and relationship quality, not maternal regulatory supportive parenting, contribute to rank-order change in self-regulation abilities. Implications of these results for research and practice are discussed. PMID:19960238

  7. Probing the solar cycle: a comparative and complementary analysis of GONG BiSON and VIRGO/LOI eigenfrequency shifts

    We use high-quality helioseismic data collected by GONG (over 4 <= l <= 140), BiSON (0 <= l <= 2) and VIRGO/LOI (0 <= l <= 8) to study the phenomenological nature of the cycle-induced (centroid) eigenfrequency variations. We have analyzed the frequency dependence of the shifts by fitting a power-law of the form ??nl ~ (?nl)?/Enl to the data (where the Enl are the mode inertias, and ? is the power-law index to be extracted). Previous studies have suggested that a relation with ? = 0 provides an adequate description of the shifts up to ? ? 3500 ?Hz. However, here we show that while nevertheless describing the shifts well up to ~2500 ?Hz, the linear scaling breaks down conspicuously at higher frequencies. Above this threshold, the shifts follow a power-law dependence with ? ~ 2. We also ahow that GONG shifts, averaged over different ranges in l together with the BiSON and LOI data averaged over their full quoted ranges, all scale at fixed frequency with the normalized mode inertia ratio Qnl (Christensen-Dalsgaard & Berthomieu 1991). This is to be expected if the solar-cycle perturbation affecting the modes is confined in the surface layers; the excellent agreement also reflects favourably on the external consistency of the different observations.

  8. Expression of Multiple Sexual Signals by Fathers and Sons in the East-Mediterranean Barn Swallow: Are Advertising Strategies Heritable?

    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.

    This autoethnography withdraws from information accumulated through a 10-year period of daily-weekly-monthly descriptive observation-recording (triangulated- parents & house-helper) of caregiving and rehabilitating of our brain injured son (survivor/care-receiver). We present it as an interactive voice of verbal conversation, thoughts, insights, and interpretations. It is delivered as a series of articulation intra-pulsated with our interrogation of societal-cultural-religious perspectives, norms and biases, and aligns with the CAP (Creative Analytical Practices) method of Ellis. This autoethnography glows from the richness of information which encapsulates the challenges confronting us the aging parent caregivers, the gradual incremental mind mending achievement of our son, and the interactive verbalizations and thoughts, of the caregivers, care-receiver, and other persons. The overwhelming mental and physical pain and struggle of the survivor and the aging caregivers and their sense of celebratory-satisfaction with rehabilitation progress are highlighted. Interpretation and valuation of positive and negative responses of other persons provide a critical matrix to this autoethnography. We intend to inform other caregivers and relevant healthcare professionals through this autoethnography. PMID:25763170

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

    2012-01-01

    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 genotypephenotype 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.

    In this cross-sectional study, we examined similarities and differences in depressive symptoms and psychological well-being between Latina maternal caregivers of persons with autism (N=29) and schizophrenia (N=33). We also explored predictors of maternal outcomes and the relationship of co-residence to them. Regression analysis found that mothers of adults with schizophrenia had lower levels of psychological well-being than mothers of youth or adults with autism. For the overall sample of mothers, co-residing with their son or daughter was significantly related to lower levels of depressive symptoms. Qualitative analysis of the nine mothers who lived apart from their son or daughter revealed that extreme behavior problems of the son or daughter and poor maternal health contributed to living apart. Despite overcoming these challenges, mothers expressed a profound sense of sadness about their son or daughters' living arrangements. PMID:20640047

    2014-04-01

    Over the past three decades, the Middle Son Valley, Madhya Pradesh, India has been the focus of archaeological, geological, and palaeoenvironmental investigations that aim to reconstruct regional climate changes in the Late Pleistocene and to understand the effects of the 74 ka Toba super-eruption on ecosystems and human populations in northern India. The most recently published model of alluvial deposition for the Middle Son Valley subdivides its alluvium into five stratigraphic formations, each associated with a specific artefact assemblage. In this study, new cross-valley topographic profiles, field observations and infrared stimulated luminescence (IRSL) age estimates are used to refine this model south of the Rehi-Son River confluence. These data not only provide insights into the fluvial history of the Son River and its response to changes in palaeoclimate, but will also inform future archaeological surveys by constraining the geomorphic context of surficial and excavated artefacts in the area.

    Resumen El Virus de Inmunodeficiencia Humana (VIH) y el Sndrome de Inmunodeficiencia Adquirida (SIDA) han sido motivo de estigmatizacin para las personas que viven con ellos. Esta estigmatizacin se ha estudiado consecuentemente desde la perspectiva de opiniones de agentes estigmatizantes. Estas opiniones han obviado sistemticamente el rol de las emociones en el proceso de estigmatizacin. Llevamos a cabo este estudio con el propsito de identificar el rol de las emociones en el proceso de estigmatizacin de las personas que viven con el virus (PVVS) por parte de profesionales de la salud. Para lograr este objetivo utilizamos un diseo exploratorio y cualitativo en el cual utilizamos la tcnica de entrevistas semiestructuradas a profundidad. La muestra estuvo compuesta por 80 profesionales de la salud y estudiantes de las siguientes especialidades: psicologa, trabajo social, medicina y enfermera. Los resultados reflejaron la existencia de emociones asociadas al VIH/SIDA tales como pena, lstima, compasin, asco, fobia y miedo entre los/as profesionales y estudiantes que participaron. Las personas participantes evidenciaron la necesidad de controlar sus emociones al interactuar con PVVS. Los resultados apuntan a la necesidad de explorar aquellos factores que mediatizan las emociones, tales como el contexto social en que se manifiestan y ante quines se revelan, para lograr entender a cabalidad el estigma que rodea al VIH/SIDA.

    This study investigated the development of mother-son relationship quality from ages 5 to 15 in a sample of 265 low-income families. Nonparametric random effects modeling was utilized to uncover distinct and homogeneous developmental trajectories of conflict and warmth; antecedents and outcomes of the trajectory groups also were examined. Four conflict trajectory groups and 3 warmth trajectory groups were identified. Difficult temperament in early childhood discriminated both conflict and warmth trajectory group membership (TGM), and adult relationship quality in early childhood was related to warmth trajectories. In addition, conflict TGM differentiated youth antisocial behavior during adolescence, and warmth trajectories predicted adolescent peer relationship quality and youth moral disengagement. Implications for socialization processes are discussed. PMID:21883153

    An explicit analytical model of surface potential profile and threshold voltage of work function engineered gate (WFEG) recessed source/drain (Re S/D) MOSFET has been presented in this paper. A two dimensional Poisson's equation has been solved with parabolic potential approximation to establish the expressions of front and back channel surface potential distribution and the threshold voltage has been derived from the minima of such obtained potential. In this work, the benefits of linearly graded binary alloy gate and recessed source/drain structures are expected to be available simultaneously in ultra short channel SOI/SON MOSFETs structures. Analytical results are compared with those obtained from the 2D MEDICI device simulator to validate our present model.

    Mutually related explicit algebraic-polynomial expressions of the orthogonalization coefficients are proposed for the biorthogonal [polynomial (Bargmann-Moshinsky), stretched, antistretched, quasistretched, and their dual] bases of the two parametric (mixed tensor and covariant) irreducible representations (irreps) of SU(n) restricted to SO(n), as well as for the projected (Smirnov-Tolstoy) and dual bases of the five-dimensional quasispin. The orthogonalization coefficients of the essentially simplified Gram-Schmidt process are expressed, up to explicitly given elementary factors, in terms of the numerator and denominator polynomials, represented as compositions of the generalized hypergeometric coefficients <3F2(...)||?? and <1F0(...)||?? and equivalent in the diagonal (denominator) and boundary cases to the A?(cabde) functions of Biedenharn and Louck. The distribution of zeros and the symmetry properties of the introduced polynomials are crucial for the conjectured solutions.

    Sun-as-a-star observations are very important for the study of the conditions within the Sun and in particular for the deep interior where higher degree modes do not penetrate. They are also of significance in this era of dramatic advances in stellar asteroseismology as they are comparable to those measured in other stars by asteroseismic missions such as CoRoT, Kepler, and MOST. More than 17 years of continuous measurements of SoHO and more than 30 years of BiSON observations provide very long data sets of uninterrupted helioseismic observations. In this work, we discuss the present status of all these facilities that continue to provide state-of-the-art measurements and invaluable data to improve our knowledge of the deepest layers of the Sun and its structural changes during the activity cycle.

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

    2007-09-01

    The role of the father in the onset and development of schizophrenic disorder/disturbance is very often secondary as compared to that of the mother. This study deals with the father's sphere in the family with a patient/son suffering from schizophrenia, the traits of his personality and his relationship with his son/patient, and with his wife/the mother of the patient. The methods applied were clinical interview, structured interview and semantic differential. The following statistical procedures were used: correlation, componential, discriminative, factor and quasicanonical analyses. The results include some characteristic excerpts from clinical interviews with patients/sons and their fathers, projective perception of current family relationships, quasicanonical analysis of the father's, mother's and son's experiences of the patient's/son's early childhood, and the projective view of the father. Among the conclusions reached, the phenomenon of "dead father" is emphasized as one of the main factors in the onset and development of schizophrenic disorder/disturbance. PMID:17914315

  18. 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?

    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. PMID:22286277

    Background 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. Methods 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. Results The adjusted odds ratios (ORs) for suicide among mothers whose son had died were 2.60 (95% CI = 1.185.73), 2.58 (1.285.20), and 4.20 (0.7922.45) 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 (0.824.62), 1.38 (0.543.49), and 2.48 (0.4015.51). Conclusions 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.

    A multiproxy study was conducted on Holocene sediments from the alpine lake Son Kul (3010 m a.s.l, 4148?33N/7507?38E) in central Tien Shan (Kyrgyzstan). The combination of high-resolution pollen, palynofacies and magnetic susceptibility data allowed reconstruction of changes in sedimentary and vegetation dynamics regionally at Son Kul between 8350 and ca 2000 cal. BP. Using pollen data to quantify climatic parameters, a quantitative reconstruction of climatic conditions was performed using the "Modern Analogue Vegetation types" (MAV) method and a ranged index of seasonality. The most temperate (e.g. moister) climate conditions occurred between 8350 and 5000-4500 cal. BP when alpine meadow vegetation was enriched in plants requiring moister conditions and trees developed regionally. Conversely, more continental and arid conditions prevailed after 4500 cal. BP with the decline of arboreal vegetation (especially Juniperus) and the extension of an alpine steppe-meadow along with a regional decrease in Poaceae. This climate transition was associated with a change in seasonality as the continentality greatly intensified after 5000-4500 cal. BP. Our results are consistent with other records from the Tien Shan range and the Chinese Province Xinjiang showing that relatively wet conditions prevailed regionally before 5000 cal. BP, whereas reduced moisture conditions were established after that time. From a more global perspective, we highlight that regional rainfall in central Tien Shan and western Central Asia is likely to be predominantly controlled by the Eastern Mediterranean cyclonic system and North Atlantic climate, as based on the close correspondence between climatic archives from western Central Asia, the Levant, the Eastern Mediterranean and Caspian Sea regions. However, the effect of monsoonal dynamics on the regional climatic system in central Tien Shan still remains dubious, since recent modelling studies have shown that no dynamic link exists between humidity in Central Asia and the Indian Summer Monsoon. This study pinpoints the need to explore the effect of remote Eurasian atmospheric circulation patterns on past climate variability in Central Asia.

  1. Hydrological changes in western Central Asia (Kyrgyzstan) during the Holocene as inferred from a palaeolimnological study in lake Son Kul

    The hydrology of western Central Asia is highly sensitive to climatic perturbations. In order to understand its long-term variability and to infer linkages between precipitation and atmospheric and oceanic systems, we conducted a thorough sedimentary and geochemical study on a composite core retrieved in lake Son Kul (central Kyrgyzstan). A multi-proxy approach was conducted on lake sediments based on grain size analyses, magnetic susceptibility, total organic carbon (TOC), total nitrogen (TN) and carbon and oxygen isotope analyses on bulk and biogenic materials (ostracoda and molluscs shells) at a resolution equivalent to ca40 years, aiming to characterise the sequence of palaeolimnological changes in Son Kul. As indicated by ?18O record of bulk carbonates, mainly consisting of aragonite, the Holocene hydrological balance was negative during most of time, suggesting an excess of evaporation (E) over precipitation (P). Limnological conditions fluctuated rapidly before 5000calyrBP indicating significant changes in regional hydrology and climate. In particular, the long-term negative hydrological balance was impeded by several short stages with marked increase of precipitation, lasting several decades to a few centuries (e.g., 8300-8200, 6900-6700, 6300-6100, 5500-5400, 5300-5200 and 3100-3000calyrBP). Precipitation changes as inferred from ?18O data are also documented by increased minerogenic detritus and higher TOC. We propose that the seasonal pattern of precipitation varied transiently in western Central Asia during the Holocene, although evaporation changes may also account for the rapid changes observed in ?18O data. When the annual water balance was less critical (P?E), the excess of water might be ascribed to increased precipitation during cold seasons mainly because winter precipitation has more negative ?18O than its summer equivalent. Conversely, when the annual water balance is negative (P?E), the moisture was mainly delivered during the warm season, as between 5000 and 2000calyrBP. Our results thus imply that moisture sources could have changed as well during the Holocene. Moisture was delivered as today mainly during summer from the extended Caspian-Aral Basin and eastern Mediterranean, although Arctic and even North Atlantic seas might be important moisture sources when seasonal precipitation was dominated by winter precipitation. We hypothesise that warming Arctic and North Atlantic seas were important for the North Hemisphere circulation during the cold season.

    A mother and son with Ehlers-Danlos syndrome (EDS) type IV and unusual congenital anomalies are described. The congenital anomalies include, in the mother, amniotic band-like constrictions on one hand, a unilateral clubfoot, and macrocephaly owing to normal-pressure hydrocephaly and, in the son, an esophageal atresia and hydrocephaly. Protein analysis of collagen III in cultured fibroblasts of the mother showed no abnormalities. However, DNA analysis of the COL3A1 gene revealed a pathogenic mutation (388G-->T) in both the mother and the son. The possible relationship between the observed congenital anomalies and EDS IV are discussed. We stress that DNA analysis of COL3A1 should be performed in all patients when there is a strong suspicion of EDS IV, despite negative findings in a collagen protein analysis. PMID:12694234

    Human populations show remarkable variation in the sex ratio at birth which is believed to be related to the parental condition. In the present study, the global variation of sex ratio at birth (SRB, proportion of male offspring born) was analyzed with respect to indirect measure of condition, the intelligence quotient (IQ). IQ correlates strongly with lifespan across nations, which makes it a good indicator of health of the large populations. Relation between three standard measures of average national IQ and SRB was studied using multiple linear regression models. Average national IQ was positively correlated with SRB ( r = 0.54 to 0.57, p < 0.001). Further, IQ emerged as a powerful predictor of SRB after controlling for the effects of all the known covariates like fertility, maternal age, polygyny prevalence, wealth, son preference, latitude, low birth weight, and neonatal mortality in the regression models. These results suggest that the striking variation of offspring sex ratio across nations could be caused in part by the difference in general condition of populations.

    New structural field data at various scale and 40Ar- 39Ar geochronological results, from the basement rocks in the Truong Son belt and Kontum Massif of Vietnam, confirm that ductile deformation and high-temperature metamorphism were caused by the Early Triassic event of the Indosinian Orogeny in the range of 250-240 Ma. A compilation of isotopic data obtained in other countries along the Sibumasu-Indochina boundary broadly indicates same interval of ages. This tectonothermal event is interpreted as the result of a synchronous oblique collision of Indochina with both Sibumasu and South China, inducing dextral and sinistral shearing along E-W to NW-SE and N-S fault zones, respectively. The collision along Song Ma follows the northwards subduction of Indochina beneath South China and the subsequent development of the Song Da zone which in turn was affected by the Late Triassic Indosinian phase of shortening. Within the Indochina plate, internal collisions occurred coevally in the Early Triassic, as along the Poko suture, at the western border of the Kontum Massif.

  6. Differences in flexibility underlie functional differences in the Ras activators Son of sevenless and Ras Guanine Nucleotide Releasing Factor 1

    Summary The Ras-specific nucleotide exchange factor Son of sevenless (Sos) is inactive without Ras bound to a distal allosteric site. In contrast, the catalytic domain of Ras Guanine Nucleotide Releasing Factor 1 (RasGRF1) is active intrinsically. By substituting residues from RasGRF1 into Sos, we have generated mutants of Sos with basal activity, partially relieved of their dependence on allosteric activation. We have performed molecular dynamics simulations showing how Ras binding to the allosteric site leads to a bias toward the active conformation of Sos. The trajectories show that Sos fluctuates between active and inactive conformations in the absence of Ras and that the activating mutations favor conformations of Sos that are more permissive to Ras binding at the catalytic site. In contrast, unliganded RasGRF1 fluctuates primarily among active conformations. Our results support the premise that the catalytic domain of Sos has evolved an allosteric activation mechanism that extends beyond the simple process of membrane recruitment. PMID:19141281

    A unique airborne Laser Absorption Spectroscopy (LAS) system has been developed by ITT Space Systems, LLC to address the needs of the National Research Council Decadal Survey Tier 2 mission for Active Sensing of CO2 Emissions over Nights, Days and Seasons (ASCENDS). This instrument has undergone multiple airborne field tests in cooperation with our partners at NASA Langley Research Center (LaRC). The instrument was built largely with off-the-shelf components and uses high reliability telecom components, including lasers, modulators and fiber amplifiers as the transmitter. Multiple wavelengths are transmitted simultaneously from a single collimator and the return signal is collected by a simple 8 telescope that is fiber coupled to a HgCdTe APD. The analog signal is sampled with a high resolution scope card housed in a National Instruments PXI chassis and the digitized signal is then passed through our custom-built software-based lock-in processing system which allows separation of the signals from the individual wavelengths. The separated signals are then used in the standard Differential Absorption Lidar (DIAL) relations to determine the integrated column differential optical depth. This presentation will give a detailed overview of this multi-frequency, single-beam, synchronous lock-in LAS instrument including the basic methodology of the measurement. Recent improvements in the lock-in methodology designed to eliminate the effects of multi- path fading and frequency dependence of the electronic components will also be discussed.

    Currently, nuclear wastes are commonly immobilized into glasses because of their long-term durability. Exposure to water for long periods of time, however, will eventually corrode the waste form and is the leading potential avenue for radionuclide release into the environment. Because such slow processes cannot be experimentally tested, the prediction of release requires a thorough understanding the mechanisms governing glass corrosion. In addition, due to the exceptional durability of glass, much of the testing must be performed on high-surface-area powders. A technique that can provide accurate compositional profiles with very precise depth resolution for non-flat samples would be a major benefit to the field. Time-of-flight secondary ion mass spectrometry (ToF-SIMS) depth profiling is an excellent tool that has long been used to examine corrosion layers of glass. The roughness of the buried corrosion layers, however, causes the corresponding SIMS depth profiles to exhibit erroneously wide interfaces. In this study, NanoSIMS was used to image the cross-section of the corrosion layers of a leached SON68 glass sample. A wedged crater was prepared by a focused ion beam (FIB) instrument to obtain a 5 improvement in depth resolution for NanoSIMS measurements. This increase in resolution allowed us to confirm that the breakdown of the silica glass network is further from the pristine glass than a second dissolution front for boron, another glass former. The existence of these two distinct interfaces, separated by only ~20 nm distance in depth, was not apparent by traditional ToF-SIMS depth profiling but has been confirmed also by atom probe tomography. This novel sample geometry will be a major benefit to efficient NanoSIMS sampling of irregular interfaces at the nanometer scale that would otherwise be obscured within ToF-SIMS depth profiles.

    This study compared reactions of mothers and fathers to the risk taking behavior of sons and daughters. Mother-father pairs (N = 52) imagined their 2-year-old boy or girl behaving in risky ways in common home situations that could, and did, result in injury. Emotional and parenting reactions to the behaviors were assessed before and after injury.

  13. Las Vegas Basin Seismic Response Project: Preliminary Results From Seismic Refraction Experiments, Las Vegas, NV.

    In May and September 2002, seismic refraction data were acquired in the Las Vegas basin. Located in the southern Basin and Range province, the cities of Las Vegas, North Las Vegas, and Henderson sit atop a fault-bounded basin with a depth of up to 5 km and basin dimensions of roughly 60 km wide (east-west) by 50 km in length (north-south). Previous isostatic gravity, seismic reflection, and aeromagnetic studies indicate that a series of sub-basins exist beneath the unconsolidated basin fill, with the deepest sub-basin occurring 5 km west of the fault block bounding the eastern edge of the basin (Frenchman Mountain). The basin is significantly deeper along its northern extremity, following the path of the fault block bounding the northern edge of the basin (Las Vegas Valley Shear Zone), and along the western edge of Frenchman Mountain. Recent, paleoseismic studies have indicated that faults in the Las Vegas region have the potential for an earthquake of M6.5 to 7.0. It is estimated that a M6.9 earthquake in the basin could produce about 11 billion dollars in damage and a significant number of deaths and/or injuries. In addition, an equivalent or larger event in the Death Valley fault zone, 150 km distance, would also be devastating to the metropolitan area of approximately 1.5 million residents. Therefore, it is essential to understand the seismic hazard posed to the Las Vegas region. This project is part of a larger collaborative effort to characterize the basin and its response to ground shaking. The University of Nevada, Las Vegas with assistance from the University of Texas at El Paso, students from UNLV and UTEP, volunteers from the community and several students from Centennial High school deployed 432 portable seismic recorders ("Texans") throughout the valley. Shot point locations were located at three quarries in the valley, one to the north, one to the east and one to the southwest. The profiles cross the Las Vegas Valley Shear zone as well as a prominent NW/SE trending step in the basin floor across which the basement drops from 2 to 4 km in depth. In addition, the profiles cross several Quaternary fault scarps, which have recently been identified as tectonic in origin. Preliminary analyses of the seismic refraction data indicate that the basin has an average P-wave velocity of 4.5 km/s and is in agreement with the estimated basin depths from isostatic gravity studies (2 to 5 km depth). Both tomographic inversion and forward modeling techniques are being used to analyze these data. These data will be used to produce a velocity model of the basin and image the basin/bedrock contact. In addition, these data will be integrated into a community model, which is being produced by the Las Vegas Basin Seismic Response working group to further assess the site response of the basin.

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

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

    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. PMID:23593964

  15. LAS - LAND ANALYSIS SYSTEM, VERSION 5.0

    NASA Technical Reports Server (NTRS)

    Pease, P. B.

    1994-01-01

    The Land Analysis System (LAS) is an image analysis system designed to manipulate and analyze digital data in raster format and provide the user with a wide spectrum of functions and statistical tools for analysis. LAS offers these features under VMS with optional image display capabilities for IVAS and other display devices as well as the X-Windows environment. LAS provides a flexible framework for algorithm development as well as for the processing and analysis of image data. Users may choose between mouse-driven commands or the traditional command line input mode. LAS functions include supervised and unsupervised image classification, film product generation, geometric registration, image repair, radiometric correction and image statistical analysis. Data files accepted by LAS include formats such as Multi-Spectral Scanner (MSS), Thematic Mapper (TM) and Advanced Very High Resolution Radiometer (AVHRR). The enhanced geometric registration package now includes both image to image and map to map transformations. The over 200 LAS functions fall into image processing scenario categories which include: arithmetic and logical functions, data transformations, fourier transforms, geometric registration, hard copy output, image restoration, intensity transformation, multispectral and statistical analysis, file transfer, tape profiling and file management among others. Internal improvements to the LAS code have eliminated the VAX VMS dependencies and improved overall system performance. The maximum LAS image size has been increased to 20,000 lines by 20,000 samples with a maximum of 256 bands per image. The catalog management system used in earlier versions of LAS has been replaced by a more streamlined and maintenance-free method of file management. This system is not dependent on VAX/VMS and relies on file naming conventions alone to allow the use of identical LAS file names on different operating systems. While the LAS code has been improved, the original capabilities of the system have been preserved. These include maintaining associated image history, session logging, and batch, asynchronous and interactive mode of operation. The LAS application programs are integrated under version 4.1 of an interface called the Transportable Applications Executive (TAE). TAE 4.1 has four modes of user interaction: menu, direct command, tutor (or help), and dynamic tutor. In addition TAE 4.1 allows the operation of LAS functions using mouse-driven commands under the TAE-Facelift environment provided with TAE 4.1. These modes of operation allow users, from the beginner to the expert, to exercise specific application options. LAS is written in C-language and FORTRAN 77 for use with DEC VAX computers running VMS with approximately 16Mb of physical memory. This program runs under TAE 4.1. Since TAE 4.1 is not a current version of TAE, TAE 4.1 is included within the LAS distribution. Approximately 130,000 blocks (65Mb) of disk storage space are necessary to store the source code and files generated by the installation procedure for LAS and 44,000 blocks (22Mb) of disk storage space are necessary for TAE 4.1 installation. The only other dependencies for LAS are the subroutine libraries for the specific display device(s) that will be used with LAS/DMS (e.g. X-Windows and/or IVAS). The standard distribution medium for LAS is a set of two 9track 6250 BPI magnetic tapes in DEC VAX BACKUP format. It is also available on a set of two TK50 tape cartridges in DEC VAX BACKUP format. This program was developed in 1986 and last updated in 1992.

    A unique, multi-frequency, single-beam, laser absorption spectrometer (LAS) that operates at 1.57 ?m has been developed for a future space-based mission to determine the global distribution of sources and sinks of atmospheric carbon dioxide (CO2). A prototype of the space-based LAS system was developed by ITT, and it has been successfully flight tested in seven airborne campaigns conducted in different geographic regions over the last four years. Flight tests were conducted over Oklahoma, Michigan, New Hampshire, and Virginia under a wide range of atmospheric conditions. Remote LAS measurements were compared to high-quality in situ measurements obtained from instrumentation on the same aircraft on spirals under the ground track of the LAS. LAS flights were conducted over a wide range of land and water reflectances and in the presence of scattered clouds. An extensive data set of CO2 measurements has been obtained for evaluating the LAS performance. These LAS test flights resulted in the first demonstration of high-precision, high-accuracy, remote laser measurements of CO2 from an airborne platform. The LAS CO2 column measurements were found to have a precision for a 10-s horizontal average (~1 km) of better than 1 ppm of CO2 over land and 1.3 ppm over water. Absolute comparisons of CO2 remote and in situ measurements showed agreement on average to better than 0.5 ppm of CO2 with a standard deviation of the agreement to better than 2 ppm of CO2. In addition, results of recent coordinated aircraft flight tests of different CO2 LAS systems and different in situ CO2 measurement systems over Oklahoma and Virginia in July-August 2009 are also discussed in this paper.

  18. Wintertime aerosol in Las Vegas, Nevada

    NASA Astrophysics Data System (ADS)

    Brown, Steven G.

    Numerous studies have found adverse health effects in subjects who live next to major roadways due to air pollution; in particular, there can be severe impacts on lung function and development in children living and/or attending school next to major roadways due to their exposure to air pollutants, including particulate matter (PM) or aerosol. The composition of aerosol at an elementary school next to a major freeway in Las Vegas, Nevada during winter 2008 was measured using a suite of measurements. An Aerodyne High Resolution Aerosol Mass Spectrometer (HR-AMS) was used to quantify the composition of non-refractory PM1 aerosol, including organic matter (OM); an Aethalometer was used to quantify black carbon (BC); a Sunset OCEC analyzer was used to measure organic and elemental carbon (OC, EC); and a particle-into-liquid system (PILS) coupled to two ion chromatographs (IC) was used to measure fine particle ions. Hi-volume PM2.5 samplers were used to collect aerosol on quartz fiber filters at between 2 and 24 hour intervals during the study, a subset of which were analyzed for PAHs and the biomass burning tracer levoglucosan. Data were analyzed by positive matrix factorization (PMF) to determine the amount of fresh, hydrocarbon-like organic aerosol (HOA), more oxidized OA (low-volatility and semi-volatile OA [LV-OOA, SV-OOA]) and biomass burning OA (BBOA). PM1 aerosol was predominantly carbonaceous, with OM plus BC accounting for 74% of the overall average 6.9 mug/m3 of PM measured. BC had a diurnal pattern similar to traffic volume, while OM was higher in the evening compared to the morning. OM was a mixture of fresh HOA, urban- and regional-scale OOA, and BBOA; in the evening, SV-OOA and BBOA peaked, while HOA concentrations were on average the same in the morning and evening, similar to BC. OM/OC ratios were low (1.52 +/-0.14 on average) during the morning rush hour (average OM = 2.4 mug/m3) when vehicular emissions dominate this near-road measurement site, and even lower (1.46 +/- 0.10) in the evening (average OM=6.3 mug/m3), when a combination of vehicular and fresh residential biomass burning emissions was typically present during a period characterized by strong atmospheric stability. While nitrate and sulfate had size distributions typical of secondary species with a sharp peak in particle diameter between 400 nm and 500 nm, OM had a broader distribution between 100 nm and 400 nm diameter particles, reflecting its combination of fresh, smaller particles and aged, larger particles. OM concentrations were on average similar between periods when the sampling site was upwind and downwind of the freeway, though during the morning OM concentrations were higher under downwind conditions, as was the fraction of HOA.

    A 37-year-old male had clinical and electrophysiological features of hereditary motor and sensory neuropathy (neuronal type) with onset in infancy, as well as histological picture of neurogenic myopathy. Two sons, aged 2 and 3 4/12 years, showed congenital contraction deformities of feet, delayed motor development, and electrophysiological features similar to those of the father. All three also presented laryngeal abnormalities, peculiar facies, short neck, narrow shoulders and protruding chest. The authors conclude that this aggregate of anomalies constitutes a "new" syndrome probably due to an autosomal dominant gene. PMID:3470161

    LAS degradation rate in Donghu Lake water under aerobic was much faster than under anaerobic condition. The half life of LAS in aerobic and anaerobic environment was 3.2 days and 57 days, respectively. The degradation rate at 25 27C was approximately 20 times higher than that at 1.5 3.5 C. In a laboratory model aquatic ecosystem, two stages of bioconcentration in fish, daphnia and snail were observed. The first stage, on second day exposure, resulted from accumulation of intact LAS, and the second stage, on 16th day exposure, was due to metabolites. The bioconcentration factor (BCF) of LAS was extremely low in the muscle of hybrid carp (0.64), but rather high (2485) in the gall bladder.

  9. A new efficient method for determining weighted power spectra: detection of low-frequency solar p-modes by analysis of BiSON data

    Fletcher, S T; Chaplin, W J; Elsworth, Y; New, R

    2011-01-01

    We present a new and highly efficient algorithm for computing a power spectrum made from evenly spaced data which combines the noise-reducing advantages of the weighted fit with the computational advantages of the Fast Fourier Transform (FFT). We apply this method to a 10-year data set of the solar p-mode oscillations obtained by the Birmingham Solar Oscillations Network (BiSON) and thereby uncover three new low-frequency modes. These are the l=2, n=5 and n=7 modes and the l=3, n=7 mode. In the case of the l=2, n=5 modes, this is believed to be the first such identification of this mode in the literature. The statistical weights needed for the method are derived from a combination of the real data and a sophisticated simulation of the instrument performance. Variations in the weights are due mainly to the differences in the noise characteristics of the various BiSON instruments, the change in those characteristics over time and the changing line-of-sight velocity between the stations and the Sun. It should be...

  10. Deletion involving D15S113 in a mother and son without Angelman syndrome: Refinement of the Angelman syndrome critical deletion region

    SciTech Connect

    Michaelis, R.C.; Skinner, S.A.; Lethco, B.A. [Greenwood Genetic Center, SC (United States)] [and others

    1995-01-02

    Deletions of 15q11-q13 typically result in Angelman syndrome when inherited from the mother and Prader-Willi syndrome when inherited from the father. The critical deletion region for Angelman syndrome has recently been restricted by a report of an Angelman syndrome patient with a deletion spanning less than 200 kb around the D15S113 locus. We report here on a mother and son with a deletion of chromosome 15 that includes the D15S113 locus. The son has mild to moderate mental retardation and minor anomalies, while the mother has a borderline intellectual deficit and slightly downslanting palpebral fissures. Neither patient has the seizures, excessive laughter and hand clapping, ataxia or the facial anomalies which are characteristic of Angelman syndrome. The proximal boundary of the deletion in our patients lies between the D15S10 and The D15S113 loci. Our patients do not have Angelman syndrome, despite the deletion of the D15S113 marker. This suggests that the Angelman syndrome critical deletion region is now defined as the overlap between the deletion found in the previously reported Angelman syndrome patient and the region that is intact in our patients. 28 refs., 6 figs.

  11. Cell-Type Specific Expression of the Vasopressin Gene Analyzed by AAV Mediated Gene Delivery of Promoter Deletion Constructs into the Rat SON In Vivo

    PubMed Central

    Salinas, Yasmmyn D.; Lubelski, Daniel; Gainer, Harold

    2012-01-01

    The magnocellular neurons (MCNs) in the supraoptic nucleus (SON) of the hypothalamus selectively express either oxytocin (Oxt) or vasopressin (Avp) neuropeptide genes. In this paper we examine the cis-regulatory domains in the Avp gene promoter that are responsible for its cell-type specific expression. AAV vectors that contain various Avp gene promoter deletion constructs using EGFP as the reporter were stereotaxically injected into the rat SON. Two weeks following the injection immunohistochemical assays of EGFP expression from these constructs were done to determine whether the expressed EGFP reporter co-localizes with either the Oxt- or Avp-immunoreactivity in the MCNs. The results identify three major enhancer domains located at ?2.0 to ?1.5 kbp, ?1.5 to ?950 bp, and ?950 to ?543 bp in the Avp gene promoter that regulate the expression in Avp MCNs. The results also show that celltype specific expression in Avp MCNs is maintained in constructs containing at least 288 bp of the promoter region upstream of the transcription start site, but this specificity is lost at 116 bp and below. Based on these data, we hypothesize that the ?288 bp to ?116 bp domain contains an Avp MCN specific activator and a possible repressor that inhibits expression in Oxt-MCNs, thereby leading to the cell-type specific expression of the Avp gene only in the Avp-MCNs.

  12. Sexy sons from re-mating do not recoup the direct costs of harmful male interactions in the Drosophila melanogaster laboratory model system.

    2005-09-01

    The empirical foundation for sexual conflict theory is the data from many different taxa demonstrating that females are harmed while interacting with males. However, the interpretation of this keystone evidence has been challenged because females may more than counterbalance the direct costs of interacting with males by the indirect benefits of obtaining higher quality genes for their offspring. A quantification of this trade-off is critical to resolve the controversy and is presented here. A multi-generation fitness assay in the Drosophila melanogaster laboratory model system was used to quantify both the direct costs to females due to interactions with males and indirect benefits via sexy sons. We specifically focus on the interactions that occur between males and nonvirgin females. In the laboratory environment of our base population, females mate soon after eclosion and store sufficient sperm for their entire lifetime, yet males persistently court these nonvirgin females and frequently succeed in re-mating them. Females may benefit from these interactions despite direct costs to their lifetime fecundity if re-mating allows them to trade-up to mates of higher genetic quality and thereby secure indirect benefits for their offspring. We found that direct costs of interactions between males and nonvirgin females substantially exceeded indirect benefits through sexy sons. These data, in combination with past studies of the good genes route of indirect benefits, demonstrate that inter-sexual interactions drive sexually antagonistic co-evolution in this model system.

    Certain aspects of the use of the Snijders-Oomen Non-verbal Intelligence Test (SON-R 6-40) in clinical and educational assessment of children with hearing impairment and children from immigrant families are discussed. Test results of 35 children per group have been compared to the data from a German-speaking control group, matched by age, sex and educational achievement of both parents. Specific differences between the three groups on both subtest and IQ levels are demonstrated. This paper provides scoring results for the three groups and discusses the differences between the test profiles. The test can be accomplished with children who have special educational needs. Results also prove the usefulness of a non verbal test in the assessment of cognitive abilities in clinical-diagnostic questions. PMID:22462294

  16. The phenomenology of solar-cycle-induced acoustic eigenfrequency variations: a comparative and complementary analysis of GONG, BiSON and VIRGO/LOI data

    NASA Astrophysics Data System (ADS)

    2001-07-01

    We use high-quality helioseismic data collected by three different observational programmes during the declining phase of activity cycle 22,Q7 and a substantial portion of the rising phase of the current cycle (23), to study the phenomenological nature of the cycle-induced (centroid) eigenfrequency variations. We have analysed the frequency dependence of the shifts by fitting a power law of the form ??nl~(?nl)?/Enl to the data (where the Enl are the mode inertias, and ? is the power-law index to be extracted). Previous studies have suggested that a relation with ?=0 provides an adequate description of the shifts up to ?~3500?Hz. However, here we show that while nevertheless describing the shifts well up to ~2500?Hz, the linear scaling breaks down conspicuously at higher frequencies. Above this threshold, the shifts follow a power-law dependence with ?~2. Our analyses (for 1600<=?<=4000?Hz) make use of observations made by the ground-based GONG over the angular degree range 4<=l<=150 the ground-based BiSON over 0<=l<=2 and the VIRGO/LOI instrument on board the ESA/NASA SOHO satellite over 0<=l<=8. We show that GONG shifts averaged over different ranges in l, together with the BiSON and LOI data averaged over their full quoted ranges, all scale at fixed frequency with the normalized mode inertia ratio QnlQ1. This is to be expected if the solar-cycle perturbation affecting the modes is confined in the surface layers; the excellent agreement also reflects favourably on the external consistency of the different observations.

  17. Shallow Crustal Configuration of the Narmada-Son Lineament Transition Zone Near the Sahdol-Katni Area of Central India Using Simultaneous Gravity and Magnetic Observations

    NASA Astrophysics Data System (ADS)

    Ghosh, G. K.; Singh, C. L.

    2011-05-01

    Gravity and magnetic studies have been carried out to map the different depth formations of alluvium, Gondwana, Vindhyan, Mahakoshal, and the crystalline basement in the Narmada-Son lineament (NSL) near the Sahdol-Katni area, India. Higher elevations in the northern part of the study area have lower gravity; the southern part of the study area, however, is moderately elevated and also has a higher gravity anomaly, which justifies the isostatic adjustment. This indicates the presence of high-density material, for example Mahakoshal rocks, in the upper crust which causes the higher anomaly value. The Mahakoshal rocks are widely exposed at Mau, Chanaura, Nadawar, Khamaria, Umria, and near the Tala-Barhi area and also extend from Sidhi to Agoni village further east of the area. The Mahakoshal rocks are thinner between the river Son and Tikwa village which causes a different gravity anomaly pattern changing from the NNE-SSW direction to the N-S direction. However, the trend of magnetic anomaly follows the same pattern toward the NNE-SSW direction, mainly because of the effect of the crystalline basement. Two magnetic highs are prominent in the Tikwa and Amarpur regions, 800 and 400 nTesla, respectively, because of the presence of the crystalline basement. The depth of the crystalline basement obtained by 2 D gravity-magnetic modelling varies from 2.7 to 2.9 km. From spectral analysis the average depth of the crystalline basement varies from 2.83 to 3.05 km. The different crustal depth sections obtained by 2 D simultaneous gravity-magnetic modelling correlate well with other constrained data.

    The Narmada-Son lineament (NSL) is one of the most prominent tectonic features which divides the Indian peninsula into two subcontinents, northern and southern India since Precambrian times. The area is seismically active and geologically complex with different geological formations. Magnetic data divides the area into two parts and more prominent magnetic highs are observed near Tikwa, Mau and Amarpur regions with 800, 600 and 400 nT, respectively due to the presence of the crystalline basement rock. Tectonic resettlement and lithological changes causes upwarpment of Mahakoshal rocks. In the present study, magnetic data interpretation is carried out for locating depth of causative body and delineating structural fault/dyke boundaries using Euler deconvolution technique. Most of the faults are oriented in the ENE-WSW direction; however, few more faults are identified which are oriented in the SE to NW direction. These fault patterns suggest that the area is exaggerated by tectonic turmoil and distressed both sedimentary to basement rocks isolating the area into numerous faulted blocks. The maximum depths (>4.5 km) observed at Katni and Umaria area and moderate depths (between 4.0 and 4.5 km) observed towards east of Katni, Ramnagar, Burwa and east of Umaria and Sarna area.

  8. Sex ratio and proportion of affected sons in sibships with X-chromosomal recessive traits: maximum likelihood estimation in truncated multinomial distributions.

    If mothers are carriers of a recessive male sex-linked disorder, their children may include females, healthy males and affected males. The composition of the possible sibships follows a multinomial distribution. If the mothers are diagnosed as carriers independently of their offspring, then the distributions are not truncated, but if they are classified as carriers after the birth of at least one affected son, the distributions are truncated. In order to avoid ascertainment bias, the statistical analyses of the corresponding data must differ. We present procedures for estimation in both the untruncated and the truncated case. The formulae obtained are applied to family data for X-chromosomal recessive retinoschisis (RS) from the region of Satakunta in southwestern Finland. Earlier studies indicated that, among the offspring of RS carriers, the sex ratio was increased. In our model, therefore, we include both the proportion of males and the proportion of affected individuals among the males. The sex ratio was significantly increased (131.0), but the proportion of affected males was slightly lower than expected (42.5%). RS seems to be the only known genetic disorder in which the offspring of carriers of the mutation include a statistically significant surplus of males. PMID:12435881

    2007-01-01

    This study applies spatial analyses to examine the consequences of accelerated urban expansion on a hydrologic system over a period of 24 years. Three sets of historical aerial photos are used in a GIS analysis to document the geomorphic history of Las Vegas Wash, which drains the rapidly growing Las Vegas urban area in southern Nevada. New spatial techniques are introduced to make quantitative measurements of the erosion at three specific time intervals in the hydrologic evolution of the channel and floodplain. Unlike other erosion studies that use two different elevation surfaces to assess erosion, this study used a single elevation surface to remove systematic and nonsystemic elevation errors. The spatial analysis quantifies channel changes for discrete time periods, calculates erosion volumes, and provides a foundation to examine how the specific mechanisms related to urban expansion have affected Las Vegas Wash. The erosion calculated over 24 years is the largest documented sediment loss attributed to the effect of rapid urban growth. ?? 2007 American Water Resources Association.

  17. Source Water Assessment for the Las Vegas Valley Surface Waters

    2003-12-01

    The 1996 amendment to the Safe Drinking Water Act of 1974 created the Source Water Assessment Program (SWAP) with an objective to evaluate potential sources of contamination to drinking water intakes. The development of a Source Water Assessment Plan for Las Vegas Valley surface water runoff into Lake Mead is important since it will guide future work on source water protection of the main source of water. The first step was the identification of the watershed boundary and source water protection area. Two protection zones were delineated. Zone A extends 500 ft around water bodies, and Zone B extends 3000 ft from the boundaries of Zone A. These Zones extend upstream to the limits of dry weather flows in the storm channels within the Las Vegas Valley. After the protection areas were identified, the potential sources of contamination in the protection area were inventoried. Field work was conducted to identify possible sources of contamination. A GIS coverage obtained from local data sources was used to identify the septic tank locations. Finally, the National Pollutant Discharge Elimination System (NPDES) Permits were obtained from the State of Nevada, and included in the inventory. After the inventory was completed, a level of risk was assigned to each potential contaminating activity (PCA). The contaminants of concern were grouped into five categories: volatile organic compounds (VOCs), synthetic organic compounds (SOCs), inorganic compounds (IOCs), microbiological, and radionuclides. The vulnerability of the water intake to each of the PCAs was assigned based on these five categories, and also on three other factors: the physical barrier effectiveness, the risk potential, and the time of travel. The vulnerability analysis shows that the PCAs with the highest vulnerability rating include septic systems, golf courses/parks, storm channels, gas stations, auto repair shops, construction, and the wastewater treatment plant discharges. Based on the current water quality data (prior to treatment), the proximity of Las Vegas Wash to the intake, and the results of the vulnerability analysis of potential contaminating activities, it is determined that the drinking water intake is at a Moderate level of risk for VOC, SOC, and microbiological contaminants. The drinking water intake is at a High level of risk for IOC contaminants. Vulnerability to radiological contamination is Moderate. Source water protection in the Las Vegas Valley is strongly encouraged because of the documented influence of the Las Vegas Wash on the quality of the water at the intake.

  18. Comprehensive Analysis of Broadband Seismic Data in Las Vegas Valley

    NASA Astrophysics Data System (ADS)

    2003-12-01

    The city of Las Vegas is one of the fastest growing metropolitan areas in the world. Its urban area is located in a relatively broad sedimentary basin in the Basin and Range Province. Acknowledging that Las Vegas of 2003 is drastically different from Las Vegas of a decade ago, our objectives are to understand and predict ground motions and evaluate the effects of possible future earthquakes and nuclear tests at Nevada Test Site (NTS) on buildings in Las Vegas. A model of the basin depth was derived from gravity data in an independent study, while a model of compressional velocity structure of the basin was derived from seismic refraction studies. We are using strong motion accelerometers regional data, as well as newly acquired broadband teleseismic data to evaluate these models, and predict ground motions at the surface. Delay times of about a dozen analyzed teleseismic P-waves show variation of up to 0.5 seconds across relatively short distances (15 km or less), providing some valuable information on basin shape and thickness. Teleseismic P-waves have favorable signal-to-noise for low frequencies (0.1 to 1.0 Hz). This provides complementary site response measurements to those obtained from regional earthquakes and explosions. Our results indicate a clear difference in site response between hard-rock and basin stations, with amplification reaching factor 5 for the basin stations. The measured P and S wave energies for the recorded data also corelate well with the existing basin depth model, providing additional constraint in modeling the basin shape and structure. We use time domain deconvolution receiver functions to constrain the position of basin boundaries and main crustal discontinuities. Finally, we simulate low frequency (f < 1 Hz) theoretical ground motion in Las Vegas Valley by an elastic finite difference code. Preliminary results show that we can predict relative amplification, as well as some of the complexity in the waveforms, even without invoking complex (and computationaly expensive) three-dimensional structural models. This work is in progress.

    NASA Astrophysics Data System (ADS)

    Bachelet, M.; Crovisier, J.; Stille, P.; Boutin, R.; Vuilleumier, S.; Geoffroy, V.

    2008-12-01

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

    Several NW-trending ductile and partly mylonitic shear zones cross the Truong Son belt of Central Vietnam, along the Song Ma and Song Ca valleys and, north of the Kontum block, from Da Nang to Aluoi and Khe Sanh. High-grade metamorphic rocks of amphibolite facies, showing a retrograde evolution and consisting of ortho- and paragneisses, metavolcanics, amphibolites, marbles and quartzites are exposed along these structures. They display a homogeneous deformation pattern characterized by a generally steeply dipping foliation and a near-horizontal to gently plunging mineral stretching lineation, indicating a strike-slip tectonic regime of deformation. Along the southernmost fault zone at least, various and consistent kinematic indicators, including S?C structures, asymmetric tails of porphyroclasts, prove that the strain and metamorphism have been generated by a phase of dominantly non-coaxial deformation with a dextral sense of shear. 40Ar? 39Ar dating, applied on the high-grade metamorphic rocks minerals occurring along these zones, provide plateau cooling ages, closely around 245 Ma, establishing that this event took place in the lowermost Triassic as an early phase of the Indosinian orogeny. The existence of Indosinian movements in Vietnam, as they have been defined by previous authors during the early century, is now accurately confirmed and this is the first insight in the occurrence of ductile strike-slip tectonics of Indosinian age along NW-SE fault zones. Well-expressed in Central Vietnam is a Cretaceous thermal and deformational overprint, marked by epimetamorphism, which took place between 90 and 120 Ma, as attested by low-temperature degassing ages. This Cretaceous event is not found further north in the Song Ma zone where younger ages appear as a result of the influence of Cenozoic shear movements along the Red River fault which displays 20-30 Ma ages. On the northern flank of Song Ca, in the Bu Khang-Phu Hoat core complex, comparable Oligocene-Lower Miocene ages (20-35 Ma), yielded by biotite and phlogopite, reflect a strong overprinting and attest to a rapid uplift of the basement.

  2. Las1 Is an Essential Nuclear Protein Involved in Cell Morphogenesis and Cell Surface Growth

    Saccharomyces cerevisiae mutations that cause a requirement for SSD1-v for viability were isolated, yielding one new gene, LAS1, and three previously identified genes, SIT4, BCK1/SLK1, and SMP3. Three of these genes, LAS1, SIT4, and BCK1/SLK1, encode proteins that have roles in bud formation or morphogenesis. LAS1 is essential and loss of LAS1 function causes the cells to arrest as 80% unbudded cells and 20% large budded cells that accumulate many vesicles at the mother-daughter neck. Overexpression of LAS1 results in extra cell surface projections in the mother cell, alterations in actin and SPA2 localization, and the accumulation of electron-dense structures along the periphery of both the mother cell and the bud. The nuclear localization of LAS1 suggests a role of LAS1 for regulating bud formation and morphogenesis via the expression of components that function directly in these processes. PMID:8582632

    The Las Campanas Redshift Survey, an optically selected survey which contains 26,418 galaxy redshifts, has been correlated with ``The First ROSAT Source Catalogue of Pointed Observations with the PSPC,'' which contains 50,408 sources from 2876 ROSAT pointed observations. Ten matches were found. The optical spectra of most of the ten matches show weak narrow emission lines. Due to their high x-ray luminosities, their high x-ray--to--optical flux ratios, and the evidence of rapid x-ray variability in the two brightest matches, we interpret the majority of these objects to be narrow-line Seyfert galaxies or ``hidden'' active galactic nuclei. Of the ten matches, only one galaxy shows the characteristics of a bona fide starburst.

    This paper presents one of the concepts of Astronomy and its consequent failure in teaching this topic in high school, even when the official documents point out the necessity of Astronomy teaching at this school level. Among the spontaneous conceptions in Astronomy that high school students carry with them, even after the end of the school, we emphasized in this research the Moon phases. The development of different strategies in relation to traditional methods, aimed to teaching-learning process on this topic was considered in this study. These strategies were devised based on the reference frame of the Meaningful Learning, as elaborated by Ausubel. The proposals presented here include the active participation of students in experimental activities and other didactic activities, for their continuous evaluation during the process. These activities finished with a Comics elaboration about the Moon phases. Therefore, the objective of this paper is to present a proposal for differentiated teaching activity about Moon phases supported by the theoretical principles of Meaningful Learning at Physics classes. Este texto foca um dos contedos de Astronomia e a consequente falha no ensino deste tema no ensino mdio, apesar de os documentos oficiais apresentarem a necessidade de se trabalhar a Astronomia neste nvel de ensino. Dentre as concepes alternativas em Astronomia que os alunos do ensino mdio carregam consigo, mesmo aps o trmino dos estudos, destacamos, nesta pesquisa, o fenmeno das fases da Lua. O desenvolvimento de estratgias diferenciadas em relao ao ensino tradicional, visando o processo de ensino-aprendizagem sobre este tema, foi contemplado neste trabalho como um dos resultados obtidos sob a luz dos referenciais da aprendizagem significativa, fundamentados em Ausubel. Segundo a proposta aqui apresentada, a participao ativa dos alunos na execuo de uma atividade experimental e outras atividades didticas, que visam sua contnua avaliao durante o processo, culmina com a elaborao de uma histria em quadrinhos envolvendo as fases da Lua. Portanto, o objetivo deste trabalho apresentar uma proposta de atividade didtica diferenciada sustentada pelos princpios tericos da aprendizagem significativa aplicada ao ensino das fases da Lua durante as aulas de Fsica no ensino mdio. En este trabajo se presenta uno de los contenidos de la Astronoma y el evidente fracaso en la enseanza del tema en la escuela secundaria, a pesar del hecho que los documentos oficiales apuntan para la necesidad de trabajar contenidos de Astronoma en este nivel. Entre los conceptos alternativos en Astronoma que los alumnos secundarios llevan consigo, an despus de terminados los estudios, destacamos aqu el fenmeno de las fases de la Luna. El desarrollo de diferentes estrategias en relacin con los mtodos tradicionales, dirigidas al proceso de enseanza-aprendizaje en este tema fue considerado en este trabajo como uno de los resultados obtenidos a la luz de los referenciales del aprendizaje significativo, tal como fueron fundamentados por Ausubel. Segn la propuesta que aqu se presenta, la participacin activa de los estudiantes en la ejecucin de una actividad experimental y otras actividades educativas destinadas a la evaluacin continua durante el proceso culmin en la elaboracin de una historieta respecto de las fases de la Luna. Por lo tanto, el objetivo de este trabajo es presentar una propuesta de actividad de enseanza diferenciada con el apoyo de los principios tericos del aprendizaje significativo aplicado a la enseanza de las fases de la luna durante las clases de fsica del ciclo secundario.

    The behavior of LAS (linear alkylbenzene sulfonate) in different environmental compartments was studied through wastewater treatment process steps in sewage treatment plants of Alicante and Benidorm (activated sludge type) as well as in Guardamar (lagoons). The fate of LAS, using a specific HPLC method, was monitored during treatment sludge compostage and soil amendment operations. Finally, the marine sediments close to a submarine wastewater sewer outfall were analyzed. The results show significant differences between distribution of LAS homologs in water and solids (sludges, sediments, and soils), as compared to the original distribution in detergent formulations, yielding a lower LAS average molecular weight in water samples. The change observed in the homolog distribution of LAS implies a reduction in the toxicity to Daphnia, because a lower average molecular weight of LAS is less toxic.

  13. La Transpiración - Movimiento del Agua a Través de las Plantas

    NSDL National Science Digital Library

    La transpiración es la pérdida de agua en forma de vapor por las plantas. El agua es absorbida del suelo por las raíces y transportada en forma líquida por el xilema hacia las hojas. En las hojas, unos pequeos poros permiten que el agua (H2O) escape a la atmósfera en forma de vapor, al tiempo que se permite la entrada de bióxido de carbono (CO2) para la fotosíntesis. De toda el agua absorbida por las plantas, menos del 5% es retenida y utilizada para crecimiento y almacenamiento. En esta lección se explicará porque las plantas pierden tanta agua, la ruta que ésta sigue dentro de la planta, como pudieran las plantas controlar la pérdida excesiva de agua y como las condiciones ambientales influyen en la pérdida de agua por las plantas.

  14. Stationary Phase-Specific Virulence Factor Overproduction by a lasR Mutant of Pseudomonas aeruginosa

    2014-01-01

    Secreted virulence factors of the human pathogen Pseudomonas aeruginosa are often under quorum sensing control. Cells lacking the quorum-sensing regulator LasR show reduced virulence factor production under typical laboratory conditions and are hypo-virulent in short-term animal infection models, yet lasR mutants are frequently associated with long-term infection in cystic fibrosis patients. Here, I show that in stationary-phase or slow-growth conditions, lasR cells continuously and strongly produce the important virulence factor pyocyanin while wild-type cells do not. Pyocyanin overproduction by lasR cells is permitted by loss of repression by RsaL, a LasR-dependent negative regulator. lasR cells also contribute pyocyanin in mixed cultures, even under cheating conditions where they depend on their wild-type neighbors for nutrients. Finally, some clinical P. aeruginosa isolates with lasR mutations can overproduce pyocyanin in the laboratory. These results imply that slow-growing clinical populations of lasR cells in chronic infections may contribute to virulence by producing pyocyanin under conditions where lasR+ cells do not.

    Sediments from the Tagus estuary (Portugal) were collected at 40 stations in July and December 2004. Total LAS concentrations ranged between 0.03 and 17.76 mg LAS.kg(-1) dry weight in July, and between 0.09 and 9.57 mg LAS.kg(-1) in December. Highest LAS concentrations were found at the upper northern part of the estuary, coincident with the localisation of an important waste water treatment station. According to the Predicted No Effect Concentration (PNEC) of 8.1 mg.kg(-1) derived for this compound, Environmental Risk Assessment (ERA) identified a hazard for the ecosystem at the station with the highest LAS concentration, and similar results are obtained by Equilibrium Partitioning Method (EPM). Nevertheless, LAS concentrations decreased significantly between samplings in the stations with the highest LAS concentrations in July, whereas increased LAS concentrations at adjacent stations were found in December. In the remaining stations, LAS concentrations were up to three orders of magnitude lower, representing no hazard for the sediment community. PMID:18228153

    PNNL deployed the ARSA radioxenon measurement system in North Las Vegas for two weeks in February and March 2006 for the purpose of measuring the radioxenon background at a level of sensitivity much higher than previously done in the vicinity of the NTS. The measurements establish what might be expected if future measurements are taken at NTS itself. The measurements are also relevant to test site readiness. A second detector, the PEMS, built and operated by DRI, was deployed in conjunction with the ARSA and contained a PIC, aerosol collection filters, and meteorological sensors. Originally, measurements were also to be performed at Mercury, NV on the NTS, but these were canceled due to initial equipment problems with the ARSA detector. Some of the radioxenon measurements detected 133Xe at levels up to 3 mBq/m3. This concentration of radioxenon is consistent with the observation of low levels of radioxenon emanating from distance nuclear reactors. Previous measurements in areas of high nuclear reactor concentration have shown similar results, but the western US, in general, does not have many nuclear reactors. Measurements of the wind direction indicate that the air carrying the radioxenon came from south of the detector and not from the NTS.

  19. Assembly Bias of Dark Matter Halos in LasDamas

    Assembly bias of dark matter halos refers to the phenomenon in which the clustering of dark matter halos of a fixed mass depends significantly on a second property, in particular: age, concentration or spin. This discovery suggests a challenge for halo occupation distribution and other models that connect galaxy properties solely to halo mass. To investigate assembly bias we use the Large Suite of Dark Matter Simulations (LasDamas) to calculate the large-scale clustering of distinct halos as a function of a variety of properties including mass. We first investigate whether some property other than mass is better able to single-handedly predict clustering, i.e., eliminate the need for a second parameter, but we find no such property. Noting that for many halos the current mass is significantly lower than the peak mass it attained over its history, we revisit assembly bias using only halos that have maintained a significant fraction of their peak mass. We find that the dependence of clustering on a second halo parameter is significantly reduced without the inclusion of these high mass-loss halos. This strongly suggests that part of the theoretical explanation for assembly bias may be that a large fraction of halos do not continually grow in mass, as assumed in spherical collapse models, but instead lose significant amounts of their mass at later times due to interactions with other halos.
