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

    Besides the unsustainable exploitation, farming activities and economic development activities, forest fire is considered as one of the major threats to biodiversity and deforestation in Vietnam. In forest ecosystems, any changes in insect communities can affect species composition, nutrient cycling and numerous other ecological processes. The impact of forest fires, however, is not equal to different insect groups. In this paper, we study the impact of forest fires to hymenopteran insects at...

  5. Son, Sent, and Servant

    2015-11-01

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

  7. Sons and daughters in China.

    Robey, B

    1985-11-01

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

  8. Achalasia in father and son.

    Achalasia has not been previously reported in father and son. A man, age 38, and his father, age 66, presented two years apart with symptoms of dysphagia and aspiration. The diagnosis of achalasia was made on the basis of x-ray and endoscopic findings and on esophageal motility studies performed on the father. Both responded well to pneumatic dilatation and have been asymptomatic for 24 months and 6 months, respectively. These cases again suggest a genetic basis for achalasia.

  9. ...And Kronos Ate His Sons

    Science.gov (United States)

    Vitiello, Giuseppe

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

  14. Preference for sons: past and present.

    Science.gov (United States)

    Li, D

    1997-10-01

    This brief article discusses the present and past preference for sons in China. The preference for sons is rooted in feudal views that men are superior to women. Preference for sons dates back to the Warring States Period, in about 500 B.C. Clan brotherhoods of men have existed for centuries. Historical records mention the practice of female infanticide. Patriarchal families believed that women were economically dependent on men and thus became their subjects. Daughters married, lived in their husband's home, and did not carry the responsibility of caring for their own parents. Couples with only daughters would seek a son-in-law to support them in old age. Rural families with no sons were looked down upon. Sons were expected to carry on the family lineage, increase the reputation of the family, and protect the family's interests. The lack of sons was a sign of humiliation and a curse. The founding of the People's Republic of China brought changes to son preference. The government attempted to increase women's status. In rural areas, women were given equal access to the land. Job opportunities were created for women during the industrialization drive. The Chinese government encouraged the repudiation of the negative impacts of the doctrines of Confucius and Mencius. Efforts were made to give men and women equal pay for equal work. Legislation was passed prohibiting arranged marriage, polygyny, and early marriage. A side effect of fertility decline is the renewed preference for sons. In Huangyan and Haining in Zhejiang, a developed province, the sex ratio at birth is normal. Sexual division of labor reinforces son preference.

    Arthur Miller, who was one of the greatest American playwrights of the 20th century. In All My Sons, different sorts of denials lead to the family’s collapse and Keller’s death. Paradoxically, the very denial that is designed to protect him from prose-cution and incarceration is followed by a chain of events that lead to Keller’s own self-imprisonment and self-imposed execu-tion. Denial also exists in the history of some countries, such as Germany, Japan and America and so on. My paper aims to ex-plore the paradox of denial both in our history and in literature works. My paper will demonstrate that denial has some negative effects both on the outer-world and the inner-world through thorough analysis on the characters in All My Sons.

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

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

    1983-01-01

    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.

Il en ressort une tension entre deux types de légitimité à occuper un espace-territoire. L’une se fonde sur une logique de confrontation/alliance et met en avant l’individu et la conquête territoriale. L’autre se fonde sur une logique de filiation et met en avant le groupe comme collectivité et l’héritage de la terre, voire l’autochtonie. Cette tension peut notamment s’expliquer par les enjeux concrets qui accompagnent ces représentations, en l’occurrence, les relations politiques et foncières au sein du groupe comme avec les communautés voisines.Rituals performed by the Kulung reveal a complex and sometimes contradictory relationship to territory. This is notably the case of the entities to which these rituals are addressed : ancestors, forest powers or the ambivalent and mediating figure of the Nagi. Tension between two forms of space-territory occupation legitimacy is revealed. One is founded upon the logic of confrontation/alliance and places individuals and territorial conquest at the forefront. The other is founded on the logic of filiation and places the group as a collective, land inheritance and even autochthony at the forefront. This tension can be explained by concrete stakes which accompany these representations, in this case : the political and land control relation both within the group and with neighbouring communities.

    To analyze desire for sons/daughters among ladies of Peshawar, Pakistan, with a view to rule out son preference and to study impact of various demographic characteristics on the subject. Cross-sectional descriptive study conducted at Combined Military Hospital, Peshawar, from August 2015 - January 2016; sampling technique was random/probability/non-purposive. Self-designed questionnaire was utilized; carrying questions pertinent to desire for sons/daughters during marital life, and demographic details. Data analyzed via descriptive analysis (SPSS-21), expressed as frequencies/percentages and mean ± standard deviation(minimum/maximum). Sons and daughters desired (dependent variables) were cross-tabulated with independent variables. Response rate was 63.25% (n-506). Data revealed following: Sons desired 3.05±2.061(1/12); Daughters desired 1.15±0.767(0/4); 6.1%(n-31) and 0.6%(n-3) desired infinite number of sons and daughters respectively, 18.2%(n-92) did not desire to have even one daughter, while 2.2%(n-11) considered it immaterial to have daughters or sons. There was a significant relation between sons desired and client's education (p<0.001), husband's education (p<0.001) and socioeconomic class (p<0.001). There was no significant impact of religion (p-0.142) on desire for sons. Impact of independent variables on daughters desired was similar but less pronounced. There was candid son preference among the respondents. Gender discrimination can be attenuated by adequately addressing son preference at all tiers.

    Sons (daughters) with criminal fathers have 2.06 (2.66) times higher odds of having a criminal conviction than those with noncriminal fathers. One additional paternal sentence increases sons' (daughters') convictions by 32 (53) percent. Compared to traditional labor market measures, the intergenerational transmission of crime is lower than that…

  13. 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 change—for instance, higher levels of education, direct exposure to official policy education materials, higher income (a proxy for rural industrialization), and agricultural mechanization—all attenuate son preference. Being younger and female are also associated with weaker son preference, and both characteristics are likely to interact with education and industrialization to further dilute son preference in the longer term. Nevertheless, our findings suggest that concerted efforts are needed to ameliorate institutional discrimination against rural people in welfare provisioning and in labor markets, and to promote multiple dimensions of gender equality, including in land rights, wage rates, and education.

  14. Resolution of pathological identification between mother and son following rhinoplasty.

    The case here described shows that severe psychological disturbance can be caused by identification between mother and son, resulting in preoccupation with a part of the body, which in the opinion of those outside the relationship, shows no gross abnormality. Similar delusional beliefs to those held by the mother were induced in the son, when he reached the age at which these beliefs occurred in the mother, in whom they were incompletely resolved. Plastic surgery, in the absence of gross deformity, brought relief of the distress caused by this type of psychopathology. Relief occurred in the conflicts of both mother and son, even though operation was on the latter, only.

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

  19. Mother-son incest as a defence against psychosis.

    Science.gov (United States)

    Bachmann, K M; Bossi, J

    1993-09-01

    In the following, a case of mother-adult son incest is described and explained from a psychoanalytical viewpoint. Two theories are put forward: (a) Mother-son incest may occur as a defence against psychosis, and (b) the incest represents an unconscious search for triangulation, a process in which external authorities (such as, for example, a court of law) may function as surrogates for persons who have been missed in the pre-oedipal past. It is therefore possible to understand mother-son incest symbolically as an indicator of pre-oedipal needs of the son and of the mother's longing for the absent partner. The incest is, however, not only a cry for help; it is also to be regarded as an attempt to solve the problem for both people involved. Looked at in this way, new ways of understanding and new possibilities for therapy emerge.

    Sons and Lovers is considered to be D.H.Lawrene's first masterpiece. Social critique and psychological exploration are two props of creative works of D.H.Lawrence. There are two points of view in literature world about the novel Sons and Lovers: One is its critical function which criticizes the destroy of capitalistic industrial civilization to human body and mind. The other is psychological analyses. The tragedy of the characters attributes to the Oedipus complex.

    Directory of Open Access Journals (Sweden)

    Valentina Ivanovna Gabdullina

    2013-11-01

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

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

  4. Violating Bell's inequality beyond Cirel'son's bound

    2002-01-01

    Cirel'son inequality states that the absolute value of the combination of quantum correlations appearing in the Clauser-Horne-Shimony-Holt (CHSH) inequality is bound by $2 \\sqrt 2$. It is shown that the correlations of two qubits belonging to a three-qubit system can violate the CHSH inequality beyond $2 \\sqrt 2$. Such a violation is not in conflict with Cirel'son's inequality because it requires a choice of pairs of qubits which is only meaningful in a local-realistic theory. The maximum allowed violation of the CHSH inequality, 4, can be achieved using the Greenberger-Horne-Zeilinger state.

    It may seem unusual for a nurse to intervene and assist a child with a learning disability, but a mental health nurse who knows the warning signs of dyslexia is able to help families who are going through a difficult time. The current article details the author's experience regarding her son's dyslexia diagnosis. For her family, a nurse was a valuable resource. The impact the struggle had not only on her son, but also her family, and the changes brought about by getting a diagnosis and treatment, demonstrate the impact that nurses can have when family-focused care is provided.

    The purpose of this paper is to analyze the conflicts between spirit and body that exist among characters in Sons and Lovers. By stating the complicated relationships of Mr. and Mrs. Morel, two sons and their mother, and the protagonist Paul and two women, Miriam and Clara, spirit and body collides and conflicts emerge from time to time. Conflicts between blood ties and lovers' affairs, moral principles and incest, and chastity and lust are reflected on char-acters, especially Paul in the novel. It concludes that Mrs. Morel's influence on Paul's spirit and thought is great. Her spiritual domination on Paul is the main factor for these conflicts. Her death at the end of the story will be a brand-new start of Paul's life.

    Smoking during pregnancy has been reported to alter levels of reproductive hormones in adult sons. From a Danish pregnancy cohort established in 1984-1987, 347 out of 5109 sons were selected according to their exposure to tobacco smoke in foetal life. From February 2005 to January 2006, a blood sample from each young man (18-21 years) was collected and analysed for reproductive hormones. There were no apparent trends of increasing or decreasing hormonal levels with increased exposure to maternal tobacco smoking during pregnancy. Only the free testosterone/free estradiol ratios increased with increased maternal smoking during pregnancy (p for trend = 0.05). No trends for increasing odds ratios for high follicle-stimulating hormone (> or =25 percentile) or low inhibin B (hormones later in life, but the data may suggest a shift in the hypothalamo-pituitary-gonadal axis towards higher androgenicity. This result was, however, of only borderline significance and could be because of chance.

  17. Fathers and sons: Freud's discovery of the Oedipus complex.

    Science.gov (United States)

    Fuchsman, Kenneth A

    2004-01-01

    Freud's path to the Oedipus complex reveals conceptual inconsistencies. These uncertainties concern fathers, brothers and sons, and the place of the oedipal triad within the family romance. Freud's uncovering of the Oedipus complex emerged, in large part, from his self-analysis of his childhood years in Freiberg. Freud's father was 20 years older than his third wife, and had two adult sons, all of whom lived in Freiberg. In 1897, when Freud announces the Oedipus complex, he stresses his love of his mother and jealousy of his father. Yet in 1924 Freud wrote that his adult brother, Philipp, had taken his father's place as the child's rival. The oedipal complex alters if there are four players rather than three. Freud's concept of an oedipal triangle does not adequately explain the psychological dynamics of his childhood. Fuller conceptual clarity would occur if the dynamics of the Oedipus complex were placed within the family context in which it unfolds.

  19. Son preference in Indian families: absolute versus relative wealth effects.

    Science.gov (United States)

    Gaudin, Sylvestre

    2011-02-01

    The desire for male children is prevalent in India, where son preference has been shown to affect fertility behavior and intrahousehold allocation of resources. Economic theory predicts less gender discrimination in wealthier households, but demographers and sociologists have argued that wealth can exacerbate bias in the Indian context. I argue that these apparently conflicting theories can be reconciled and simultaneously tested if one considers that they are based on two different notions of wealth: one related to resource constraints (absolute wealth), and the other to notions of local status (relative wealth). Using cross-sectional data from the 1998-1999 and 2005-2006 National Family and Health Surveys, I construct measures of absolute and relative wealth by using principal components analysis. A series of statistical models of son preference is estimated by using multilevel methods. Results consistently show that higher absolute wealth is strongly associated with lower son preference, and the effect is 20%-40% stronger when the household's community-specific wealth score is included in the regression. Coefficients on relative wealth are positive and significant although lower in magnitude. Results are robust to using different samples, alternative groupings of households in local areas, different estimation methods, and alternative dependent variables.

  20. Like Father, Like Son? Intergenerational Educational Mobility in India.

    2015-12-01

    Using the nationally representative India Human Development Survey (IHDS), we create a unique son-father matched data set that is representative of the entire adult male population (aged 20-65) in India. We use these data to document the evolution of intergenerational transmission of educational attainment in India over time, among different castes and states for the birth cohorts of 1940-1985. We find that educational persistence, as measured by the regression coefficient of father's education as a predictor of son's education, has declined over time. This implies that increases in average educational attainment are driven primarily by increases among children of less-educated fathers. However, we do not find such a declining trend in the correlation between educational attainment of sons and fathers, which is another commonly used measure of persistence. To understand the source of such a discrepancy between the two measures of educational persistence, we decompose the intergenerational correlation and find that although persistence has declined at the lower end of the fathers' educational distribution, it has increased at the top end of that distribution.

    Bladder cancer may be caused by external factors like tobacco smoking, but may also be familial. We report on a father and son who developed this tumour at the ages of 45 and 35. Testing various genetic markers including the mismatch repair proteins MLH1, MSH2 and MSH6, whose loss is associated with a higher risk for hereditary non-polyposis colorectal cancer (HNPCC, Lynch syndrome), did not point to a familial disease. Thus the heavy smoking habits of the two patients must be considered as causal.

    1999-07-01

    A case of a 16-year-old male who committed a sexual matricide following years of mother-son incest is reported. After murdering his mother by strangulation, which itself was sexually arousing, the youngster engaged in both vaginal and anal necrophilia. The homicide occurred while the perpetrator was in a dissociative state and experiencing what has been referred to as a catathymic crisis: the sudden release of emotionally charged psychic conflict and tension, resulting in extreme violence within an interpersonal bond. Discussion of maternal image and maternal sexual conduct in relationship to the psychosexual development of adolescent males offers insight into the motivation in this extremely rare case.

    2012-01-01

    This article examines the recent rise in the sex ratio at birth in Vietnam and relates its emergence to kinship systems and ethnic composition using 2009 census micro-data. Presentation of the main socioeconomic and ethnic differentials in birth masculinity is followed by a review of the three intermediate factors leading to increases in the sex ratio at birth: prenatal technology, declining fertility, and gender bias. An indirect measurement of fertility behavior is used to demonstrate the close association between levels of the sex ratio at birth and the intensity of son preference. Data on household composition indicate that Vietnam is characterized by the co-existence of kinship patterns typical of East and Southeast Asia. Son preference in Vietnam is found to be related to the prevalence of more traditional patrilineal systems. The article concludes by considering the implications of the cultural dimensions of prenatal sex selection for policy responses and for the likely future change in the sex ratio at birth.

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

    In the ever changing field of reproductive medicine, clinics are regularly confronted with requests for novel variants of medically assisted reproduction. Particularly third-party (assisted) reproduction, which requires the involvement of an oocyte or sperm donor, is ethically and psychologically complex due to the parties involved, but nevertheless widely accepted. A particular type of third party reproduction concerns intrafamilial medically assisted reproduction (IMAR), where the donor is a family member of the recipients. In IMAR, some of the ethical and psychological issues associated with third party reproduction are intensified. The precise impact and consequences, however, remain speculative due to the lack of information regarding IMAR. Both the ESHRE Task Force on Ethics and Law and the Human Fertilization and Embryology Authority have recently highlighted the lack of information and the need for debate. In order to contribute to the discussion and knowledge on IMAR, we present a couple that recently visited our academic clinic with a request for a very particular variant of IMAR: first degree, intergenerational father-to-son sperm donation. As our academic hospital did not have experience with this variant of IMAR, our interdisciplinary Ethics Committee for Reproductive Medicine extensively discussed the request, resulting in an advisory report on the ethics of IMAR in general and father-to-son sperm donation in particular. Here, we will first present the andrological and social background of the couple and subsequently discuss the ethical considerations that led to the approval of their request. We will conclude the paper with recommendations for a morally sound practice of IMAR.

  15. Net aboveground biomass declines of four major forest types with forest ageing and climate change in western Canada's boreal forests.

    Biomass change of the world's forests is critical to the global carbon cycle. Despite storing nearly half of global forest carbon, the boreal biome of diverse forest types and ages is a poorly understood component of the carbon cycle. Using data from 871 permanent plots in the western boreal forest of Canada, we examined net annual aboveground biomass change (ΔAGB) of four major forest types between 1958 and 2011. We found that ΔAGB was higher for deciduous broadleaf (DEC) (1.44 Mg ha(-1)  year(-1) , 95% Bayesian confidence interval (CI), 1.22-1.68) and early-successional coniferous forests (ESC) (1.42, CI, 1.30-1.56) than mixed forests (MIX) (0.80, CI, 0.50-1.11) and late-successional coniferous (LSC) forests (0.62, CI, 0.39-0.88). ΔAGB declined with forest age as well as calendar year. After accounting for the effects of forest age, ΔAGB declined by 0.035, 0.021, 0.032 and 0.069 Mg ha(-1)  year(-1) per calendar year in DEC, ESC, MIX and LSC forests, respectively. The ΔAGB declines resulted from increased tree mortality and reduced growth in all forest types except DEC, in which a large biomass loss from mortality was accompanied with a small increase in growth. With every degree of annual temperature increase, ΔAGB decreased by 1.00, 0.20, 0.55 and 1.07 Mg ha(-1)  year(-1) in DEC, ESC, MIX and LSC forests, respectively. With every cm decrease of annual climatic moisture availability, ΔAGB decreased 0.030, 0.045 and 0.17 Mg ha(-1)  year(-1) in ESC, MIX and LSC forests, but changed little in DEC forests. Our results suggest that persistent warming and decreasing water availability have profound negative effects on forest biomass in the boreal forests of western Canada. Furthermore, our results indicate that forest responses to climate change are strongly dependent on forest composition with late-successional coniferous forests being most vulnerable to climate changes in terms of aboveground biomass. © 2015 John Wiley & Sons Ltd.

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

    El clásico tratamiento de las mujeres como minoría desde la sociología se halla contemporáneamente interrelacionado con las políticas de igualdad tejidas en torno a las mujeres. Pasado y presente, teoría y práctica se unen para mostrar que las teorías no son accidentales ni fortuitas sino que acarrean importantes consecuencias en la acción, pudiendo dar lugar a intervenciones en la vida pública, que es lo que, a mi entender, confiere su sentido a la. sociología y, en particular, a la sociología del género. El título alude a la existencia de un importante desarrollo en sociología de la temática de las minorías, que traemos a colación por cuanto desde muy temprano dicha ciencia refirió este tema a las mujeres, desarrollo que seguiremos en este artículo. La conceptualización de las mujeres como minoría se traducirá, en términos de políticas públicas, en lo que se conoce como medidas de acción o discriminación positiva impulsadas, en lo que a las mujeres atañe, por el movimiento feminista.

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

    Full Text Available Bat communities of mainland Southeast Asia can be highly diverse. Many are under threat. Despite this, regional faunal composition is not well documented for many areas, including regions of Vietnam.  We assessed the biodiversity of bats in a watershed protection forest in the southeastern Truong Son (Annamite Mountains, southwestern Quang Ngai Province, Vietnam in 2011–2013.  Twenty species of insectivorous bats were documented including a high diversity of Murina species Tube-nosed Bats.  Diversity and abundance indices were compared with that recorded previously in two nature reserves and one national park in Vietnam, and were higher or comparable in several measures despite the lack of a karst substrate for roosts.  Reproduction in the insectivorous bat fauna coincided with the early rainy season.  In the late dry season, pregnant females of several species were observed but volant juveniles were not present, whereas in the early wet season adult females were lactating or post-lactating and volant juveniles of nine species were detected.  We recorded echolocation calls of 14 bat species; for each species, we compared features of calls with those reported previously in other Asian localities.  For some species we found discrepancies in call metrics among studies, perhaps suggesting a greater hidden biodiversity of bats in Southeast Asia.

    Soluble organic nitrogen (SON) is recognized as a sensitive indicator of soil nitrogen status. The present work was conducted in the temperate forests of northeast China where soils are typically characterized by high organic matter and high organic nitrogen content, and soil sampling was made in early spring just after the freeze-thaw period. The water extracted SON pools in the organic layer of forest soils were measured within the range from 156.0 mg·kg-1 to 292.6 mg·kg-1, a similar magnitude of salt solution extracted SON pools reported in literatures. However, the water soluble SON pools in 0-15 cm mineral soils in present study were much higher (3-10 times) than any other reports, ranging from 58.6 mg·kg-1 to 125.2 mg·kg-1. Water soluble SON varied markedly among the soils under different forests and at different sites. The SON in water extracts were positively and significantly correlated to soil organic matter and total nitrogen contents, but negatively correlated to microbial biomass nitrogen (MBN). The reasons of the abnormally large SON pools and the negative correlations between SON and MBN in the 0-15cm mineral soils in this study were specially discussed.

    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

    The Pakistan Institute for Environment-Developed Action Research (PIEDAR) has been active during 1992-95 in 25 rural villages of Kabirwala tahsil, Khanewal District, Punjab region, Pakistan. Participatory rural appraisal strategies are used to help communities understand the relationship between family size and sustainable land use patterns. The fertility rate in villages is over 6 children per woman. Over 9/10 women are familiar with the concept of family planning, 7/10 know of a specific method, but only 1/10 uses contraception. Religious taboos are but one reason for the gap between knowledge and use. 15% of couples report opposition by the husband or mother-in-law. A major determinant of large family size is attributed to problem of land security, which is prevalent throughout the province. About 50% of arable land is tied up in legal battles. The farms use a wheat-cotton cropping pattern, which relies on intensive labor inputs for peak periods. Many sons help families retain the land. The Village Organization was directed to focus on the land use problems of villages and to make recommendations. Action plans are developed with step by step implementation for every land parcel in order to increase productivity. Villagers working within this community organization experience how exchanges can be made to benefit each other. The structural organization of this emerging network is useful for cutting across social, traditional, and hierarchical structures to become a new foundation for economic relations. Traditional centers of power become useless to the economic functioning of the community, and more democratic forms of governance emerge. It has been argued that rural fertility is not influenced by tradition and irrationality but by socioeconomic necessity. If so, time will change reproductive trends; unfortunately, the process of social change is slow. Independent catalytic agents are needed for speeding up the process, while civil society needs the State to

    Sons and Lovers is one of Lawrence’s most famous novels. It mainly concerns about the love affairs among the main character-Paul, his mother and his two girlfriends. The mother’s strange love has affected the boys for a long time, which even has made him lose the ability to love other girls. As a result, Paul gradually has the“Oedipus Complex”towards his mother, and it has influenced the whole lifetime of himself. During the competition of grasp the heart of Paul, Miriam and Clara are all the los-ers, while they both can’t drag Paul out of the influence from his mother. It is not until the death of his mother does Paul finally escape from the control of his mother. All the origins can be concluded into one thing-that is the Paul’s“Oedipus Complex”towards his mother. What is the“Oedipus Complex”, and how does it reflect in the main content? How does it influence the emotions of Paul step by step? This essay will elaborate it in detail.

    2014-02-01

    The SON protein is a ubiquitously expressed DNA- and RNA-binding protein primarily localized to nuclear speckles. Although several early studies implicated SON in DNA-binding, tumorigenesis and apoptosis, functional significance of this protein had not been recognized until recent studies discovered SON as a novel RNA splicing co-factor. During constitutive RNA splicing, SON ensures efficient intron removal from the transcripts containing suboptimal splice sites. Importantly, SON-mediated splicing is required for proper processing of selective transcripts related to cell cycle, microtubules, centrosome maintenance, and genome stability. Moreover, SON regulates alternative splicing of RNAs from the genes involved in apoptosis and epigenetic modification. In addition to the role in RNA splicing, SON has an ability to suppress transcriptional activation at certain promoter/enhancer DNA sequences. Considering the multiple SON target genes which are directly involved in cell proliferation, genome stability and chromatin modifications, SON is an emerging player in gene regulation during cancer development and progression. Here, we summarize available information from several early studies on SON, and highlight recent discoveries describing molecular mechanisms of SON-mediated gene regulation. We propose that our future effort on better understanding of diverse SON functions would reveal novel targets for cancer therapy.

    We review patterns and processes important for biodiversity in the Fennoscandian boreal forest, describe man`s past and present impact and outline a strategy for conservation. Natural disturbances, particularly forest fire and gap formation, create much of the structural and functional diversity in forest ecosystems. Several boreal plants and animals are adapted to fire regimes. In contrast, many organisms (epiphytic lichens, fungi, invertebrates) require stable conditions with long continuity in canopy cover. The highly mechanized and efficient Fennoscandian forest industry has developed during the last century. The result is that most natural forest has been lost and that several hundreds of species, mainly cryptograms and invertebrates, are threatened. The forestry is now in a transition from exploitation to sustainable production and has recently incorporated some measures to protect the environment. Programmes for maintaining biodiversity in the boreal forest should include at least three parts. First, the system of forest reserves must be significantly improved through protection of large representative ecosystems and key biotopes that host threatened species. Second, we must restore ecosystem properties that have been lost or altered. Natural disturbance regimes must be allowed to operate or be imitated, for example by artificial fire management. Stand-level management should particularly increase the amount of coarse woody debris, the number of old deciduous trees and large, old conifers, by using partial cutting. Third, natural variation should also be mimicked at the landscape level, for example, by reducing fragmentation and increasing links between landscape elements. Long-term experiments are required to evaluate the success of different management methods in maintaining biodiversity in the boreal forest. (au) 260 refs.

  15. SON68 glass dissolution driven by magnesium silicate precipitation

    Fleury, Benjamin; Godon, Nicole; Ayral, André; Gin, Stéphane

    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

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

    2013-01-01

    Maternal overweight and obesity in pregnancy has been associated with earlier age of menarche in daughters as well as reduced semen quality in sons.

    The depiction of human emotions is never lacking in filmography, and affection between family members accounts for the top spot to become the most deeply touching one, especially the father-son relationship. Compared with mother-daughter and mother-son relationship, father-son relationship is often full of tension, turning out to be more introverted. So, in which way do films and television shows at home and broad represent vividly and truly about the father-child relationship?

    Forests play an important role in regional and global carbon (C) cycles. With extensive afforestation and reforestation efforts over the last several decades, forests in East Asia have largely expanded, but the dynamics of their C stocks have not been fully assessed. We estimated biomass C stocks of the forests in all five East Asian countries (China, Japan, North Korea, South Korea, and Mongolia) between the 1970s and the 2000s, using the biomass expansion factor method and forest inventory data. Forest area and biomass C density in the whole region increased from 179.78 × 10(6) ha and 38.6 Mg C ha(-1) in the 1970s to 196.65 × 10(6) ha and 45.5 Mg C ha(-1) in the 2000s, respectively. The C stock increased from 6.9 Pg C to 8.9 Pg C, with an averaged sequestration rate of 66.9 Tg C yr(-1). Among the five countries, China and Japan were two major contributors to the total region's forest C sink, with respective contributions of 71.1% and 32.9%. In China, the areal expansion of forest land was a larger contributor to C sinks than increased biomass density for all forests (60.0% vs. 40.0%) and for planted forests (58.1% vs. 41.9%), while the latter contributed more than the former for natural forests (87.0% vs. 13.0%). In Japan, increased biomass density dominated the C sink for all (101.5%), planted (91.1%), and natural (123.8%) forests. Forests in South Korea also acted as a C sink, contributing 9.4% of the total region's sink because of increased forest growth (98.6%). Compared to these countries, the reduction in forest land in both North Korea and Mongolia caused a C loss at an average rate of 9.0 Tg C yr(-1), equal to 13.4% of the total region's C sink. Over the last four decades, the biomass C sequestration by East Asia's forests offset 5.8% of its contemporary fossil-fuel CO2 emissions. © 2014 John Wiley & Sons Ltd.

  1. Mothers' causal explanations for their son's schizophrenia: relationship to depression and guilt.

    1994-08-01

    This study investigated the relationship between mothers' causal explanations for their son's schizophrenia and the depression and guilt mothers experience. Thirty-three mothers who were primary caregivers to a schizophrenic son were interviewed using the Causal Dimension Scale and the Multiscore Depression Inventory. Twenty-nine mothers generated 50 causal explanations for their son's schizophrenia. The most frequently cited causal category was physiological/biological factors. Guilt was associated with causal explanations characterized as internal, whereas depression was unrelated to causal dimensions. The findings support the need to assess mothers' causal explanations for their son's schizophrenia and to research the health consequences of causal explanations.

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

    2016-02-01

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

  8. 'Too many girls, too much dowry': son preference and daughter aversion in rural Tamil Nadu, India.

    2008-10-01

    The southern Indian state of Tamil Nadu has experienced a dramatic decline in fertility, accompanied by a trend of increased son preference. This paper reports on findings from qualitative interviews with women in rural villages about their fertility decision-making. Specifically addressed are the reasons behind increasing son preference and the consequences of this change. Findings suggest that daughter aversion, fuelled primarily by the perceived economic burden of daughters due to the proliferation of dowry, is playing a larger role in fertility decision-making than son preference. The desire for a son is often trumped by the worry over having many daughters. Women use various means of controlling the sex of their children, which in this study appear to be primarily female infanticide. It is important to distinguish between son preference and daughter aversion and to examine repercussions of low fertility within this setting.

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

    Some of the genetic benefit hypotheses put forward to explain multiple male mating (polyandry) predict that sons of polyandrous females will have an increased competitive ability under precopulatory or post-copulatory competition via paternally inherited traits, such as attractiveness or fertilization efficiency. Here, we tested these predictions by comparing the competitive ability of sons of experimentally monandrous and polyandrous female bank voles (Myodes glareolus), while controlling for potential material and maternal effects. In female choice experiments, we found no clear preference for sons of either monandrous or polyandrous mothers. Moreover, neither male type was dominant over the other, indicating no advantage in precopulatory male contest competition. However, in competitive matings, sons of polyandrous mothers significantly increased their mating efforts (mating duration, intromission number). In line with this, paternity success was biased towards sons of polyandrous mothers. Because there was no evidence for maternal effects, our results suggest that female bank voles gain genetic benefits from polyandry.

  11. Cluster Forests

    Yan, Donghui; Jordan, Michael I

    2011-01-01

    Inspired by Random Forests (RF) in the context of classification, we propose a new clustering ensemble method---Cluster Forests (CF). Geometrically, CF randomly probes a high-dimensional data cloud to obtain "good local clusterings" and then aggregates via spectral clustering to obtain cluster assignments for the whole dataset. The search for good local clusterings is guided by a cluster quality measure $\\kappa$. CF progressively improves each local clustering in a fashion that resembles the tree growth in RF. Empirical studies on several real-world datasets under two different performance metrics show that CF compares favorably to its competitors. Theoretical analysis shows that the $\\kappa$ criterion is shown to grow each local clustering in a desirable way---it is "noise-resistant." A closed-form expression is obtained for the mis-clustering rate of spectral clustering under a perturbation model, which yields new insights into some aspects of spectral clustering.

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

    This article is a first-person account of a father's journey to lovingly accept his young gender-variant son, who began to show traits and preferences more common to girls almost from birth. The dad's efforts to discover constructive parenting strategies for raising his boy are also detailed. Experiences described begin with guilt and awareness of his own difficulty in coming to terms with his son's behavior, progress toward seeking and finding support and guidance, and eventually learning to embrace his son as he is, perhaps with questions about his own liberality and apprehensions about his boy's future.

    Predicting long-term trends in forest growth requires accurate characterisation of how the relationship between forest productivity and climatic stress varies across climatic regimes. Using a network of over two million tree-ring observations spanning North America and a space-for-time substitution methodology, we forecast climate impacts on future forest growth. We explored differing scenarios of increased water-use efficiency (WUE) due to CO2 -fertilisation, which we simulated as increased effective precipitation. In our forecasts: (1) climate change negatively impacted forest growth rates in the interior west and positively impacted forest growth along the western, southeastern and northeastern coasts; (2) shifting climate sensitivities offset positive effects of warming on high-latitude forests, leaving no evidence for continued 'boreal greening'; and (3) it took a 72% WUE enhancement to compensate for continentally averaged growth declines under RCP 8.5. Our results highlight the importance of locally adapted forest management strategies to handle regional differences in growth responses to climate change. © 2016 John Wiley & Sons Ltd/CNRS.

    It has been suspected that cell-cycle progression might be functionally coupled with RNA processing. However, little is known about the role of the precise splicing control in cell-cycle progression. Here, we report that SON, a large Ser/Arg (SR)-related protein, is a splicing cofactor contributing to efficient splicing of cell-cycle regulators. Downregulation of SON leads to severe impairment of spindle pole separation, microtubule dynamics, and genome integrity. These molecular defects result from inadequate RNA splicing of a specific set of cell-cycle-related genes that possess weak splice sites. Furthermore, we show that SON facilitates the interaction of SR proteins with RNA polymerase II and other key spliceosome components, suggesting its function in efficient cotranscriptional RNA processing. These results reveal a mechanism for controlling cell-cycle progression through SON-dependent constitutive splicing at suboptimal splice sites, with strong implications for its role in cancer and other human diseases.

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

    Directory of Open Access Journals (Sweden)

    Keera Allendorf

    2012-10-01

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

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

    Science.gov (United States)

    Shengold, L

    1980-01-01

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

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

    Science.gov (United States)

    Jasienska, Grazyna; Nenko, Ilona; Jasienski, Michal

    2006-01-01

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

  15. Matricide by Mentally Disordered Sons: Gaining a Criminological Understanding Beyond Mental Illness--A Descriptive Study.

    2015-12-01

    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. © The Author(s) 2014.

  18. History of son preference and sex selection in India and in the west.

    Science.gov (United States)

    Bandyopadhyay, Sutapa; Singh, Amarjeet

    2003-01-01

    In the history of mankind, there was a time when women dominated the world. In due course of time, as the patriarchal societies evolved, the status of women gradually declined. Sons were preferred to daughters. In India, the Brahmin community promoted such customs and rituals, which gave more and more importance to sons eg. Lighting the funeral pyre of the father was told to be a pre-condition for salvation of his spirit. Similarly, in western civilization also women were considered to be weak. In consonance with such a mind-set man has been trying various techniques for sex-selection since antiquity eg. for acquiring a son choosing a special day, time and posture for sexual intercourse, special diet, charms and amulet and prayers etc. In Vedas also punsavana karma has been described as a technique for acquiring a son. Apart from these techniques, female infanticide has also been used as a way to create a male dominated, son-worshipping society. On development of the technique of ultrasonography as an example of progress of science and technology, man has devised a new way of killing females in womb itself, which has resulted in continuous decline in female: male sex ratio in India. To stop this, Indian Govt. promulgated PNDT Act 1994. But considering the widely prevalent practice of use of various regimen of sex-pre-selection by people as well as unscrupulous medical practitioners, Govt. of India has amended this Act (2002). Still, as authors have found in one of their studies, sex-selection drugs are being used widely by north Indians for getting a son. Here, it should be noted that sex-selection methods are being used in west also. But the perspective is different. There, it is not used for female feticide or for acquiring a son. Rather, it is more an effort towards demonstrating the control of man over the NATURE.

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

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

  4. Son Preference in India: Shedding Light on the North-South Gradient

    Directory of Open Access Journals (Sweden)

    2014-12-01

    Full Text Available Dieser Beitrag liegt nur in englischer Sprache vor. Son preference is widespread in India and deep-rooted in its history. It is a matter of concern because it produces an imbalanced juvenile sex ratio. There are far fewer girls than boys. The figures vary greatly among the Indian states suggesting a major north-south gradient in son preference accompanied by a minor west-east gradient. The aim of this paper is to explain the regional pattern. We provide an application of the value of children-approach according to which the decision to have children is made on the calculus of benefits and costs related to children. In the light of the socioeconomic and sociocultural background in India, we propose that (potential parents’ expectations of benefits and costs are biased in favour of sons. This is suggested, therefore, as the key motivation for the preference for male offspring. However, region-specifics in the level of affluence, the educational level, the mode of production, the meaning and importance of religion, and the kinship regime are assumed to produce stronger son preference in north India compared to south India. This mediation-model is tested using the Indian sub-sample of the international Value of Children-study. Data were collected in Uttar Pradesh (north-central India and Puducherry (south-east India. Mothers aged 16 to 65 were interviewed in 2002 and 2010. Based on 1,173 respondents, a structural equation model was carried out to test the hypothesised composition effects related to the region and the mediating position of sex-specific benefits and costs. Initial findings confirm that the national son preference pattern is more likely to be found among north Indian mothers than south Indian mothers. As assumed, the sex-specific balance of benefits and costs contributes to the explanation of son preference. However, there is little evidence that the benefits and costs mediate between the region-specific socioeconomic and

  5. Two Dimensional Analytical Modeling for SOI and SON MOSFET and Their Performance Comparison

    2011-01-01

    Full Text Available During last few decade continuous device performance improvements have been achieved through a combination of device scaling, new device structures and material property improvement to its fundamental limits. Conventional silicon (bulk CMOS technology can’t overcome the fundamental physical limitations belong to sub-micro or nanometer region which leads to alternative device technology like Silicon-on-Insulator (SOI technology and its recent innovative modification Silicon-On-Nothing (SON MOSFET. Analytical simulation is very important to understand the relative performance of those devices under different structural and operational parameter variations. For present analytical simulation asymmetric structure of Silicon-On-Insulator (SOI MOSFET and Silicon-On-Nothing (SON MOSFET are considered. The proposed structure of SON MOSFET is similar to that of the SOI MOSFET with the only exception being the oxide layer here is substituted with air which has much lower permittivity than Silicon-dioxide. Variation of threshold voltage against effective channel lengths is compared for both the structures. From our simulation it is observed that the proposed SON model has lower drain to source current (IDS than SOI model. In our modeling based on solution of two dimensional Poisson’s equation short channel effects such as DIBL and fringing field effects are also taken into account. SON is found to provide better suppression of SCE s than SOI. The results predicted by our analytical simulation hold good agreement with experimental results.

    Muñoz-Silva, Alicia; Sánchez-García, Manuel

    2004-01-01

    The authors apply descriptive and sequential analyses to a mother's distancing strategies toward her 3-year-old twin sons in puzzle assembly and book reading tasks. One boy had normal hearing and the other a mild hearing loss (threshold: 30 dB). The results show that the mother used more distancing behaviors with the son with a hearing loss, and thus gave greater encouragement to this son's cognitive development. These results differ from those of previous studies of deaf or hard of hearing children, whose participants generally had severe or profound hearing loss. In those studies, parents of deaf children used more low-level distancing than parents of normally hearing children. The results of the present study are discussed in terms of their implications for the parenting of twins and of children with mild hearing loss.

  11. Court says mother has right to stop HIV drugs for son.

    Science.gov (United States)

    1998-10-02

    A mother in Maine was charged with child neglect for refusing to administer triple combination therapy to her 4-year-old son, who is HIV positive. The mother based her decision on her own experience with monotherapy and on her older daughter's experiences of the harmful side effects of AZT. Upon her daughter's death, the mother discontinued AZT treatment for herself and her son. After the mother refused a pediatrician's suggestion to start triple combination therapy for her son, the doctor reported the mother to the Department of Human Services, who then charged her with neglect. According to Newport District Judge Douglas Clapp, the mother has shown great concern for her child, and since the relative advantages of the proposed treatment are unclear, the ultimate decision of treatment should be the mother's decision. Many AIDS advocates have stated that antiretroviral therapy has shown significant benefits and recommend that treatment decisions be reached through a trusting partnership between patients and their doctors.

  12. Marital conflict and boys' peer relationships: the mediating role of mother-son emotional reciprocity.

    Lindsey, Eric W; MacKinnon-Lewis, Carol; Campbell, Jessica; Frabutt, James M; Lamb, Michael E

    2002-12-01

    This study examined the role of mother-son emotional reciprocity in connections between marital conflict and the quality of boys' peer relationships. Parents from 84 intact families with preadolescent boys reported on the level of conflict in their marital relationship. Observations of mother-son interaction were coded for emotional reciprocity, and assessments of boys' peer relationships were obtained from both teachers and classmates. No direct connection between marital conflict and boys' peer relationships was observed. Rather, marital conflict affected boys' social competence indirectly, through its effect on the emotions expressed between mother and son. The findings support the proposal that emotional processes play an important role in connections between marital conflict and children's peer relationships and suggest that family emotional expressiveness deserves greater attention in both research and intervention.

  15. Vaccinating sons against HPV: results from a U.S. national survey of parents.

    Directory of Open Access Journals (Sweden)

    Jaime L Taylor

    Full Text Available 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 11-17 year old sons against HPV. METHODS: We compiled data from a U.S. national sample of 779 parents with sons 11-17 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 1.45-2.26. Sons covered by private health insurance had decreased odds of HPV vaccination (OR 0.56 95% CI 0.37-0.83. Lastly, parents who had discussed sexual health topics with their sons were more likely to vaccinate (OR 1.61; 95% CI 1.37-1.89. 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.

  16. Forest dynamics.

    Science.gov (United States)

    Frelich, Lee

    2016-01-01

    Forest dynamics encompass changes in stand structure, species composition, and species interactions with disturbance and environment over a range of spatial and temporal scales. For convenience, spatial scale is defined as individual tree, neighborhood, stand, and landscape. Whether a given canopy-leveling disturbance will initiate a sequence of development in structure with little change in composition or initiate an episode of succession depends on a match or mismatch, respectively, with traits of the dominant tree species that allow the species to survive disturbance. When these match, certain species-disturbance type combinations lock in a pattern of stand and landscape dynamics that can persist for several generations of trees; thus, dominant tree species regulate, as well as respond to, disturbance. A complex interaction among tree species, neighborhood effects, disturbance type and severity, landform, and soils determines how stands of differing composition form and the mosaic of stands that compose the landscape. Neighborhood effects (e.g., serotinous seed rain, sprouting, shading, leaf-litter chemistry, and leaf-litter physical properties) operate at small spatial extents of the individual tree and its neighbors but play a central role in forest dynamics by contributing to patch formation at stand scales and dynamics of the entire landscape. Dominance by tree species with neutral to negative neighborhood effects leads to unstable landscape dynamics in disturbance-prone regions, wherein most stands are undergoing succession; stability can only occur under very low-severity disturbance regimes. Dominance by species with positive effects leads to stable landscape dynamics wherein only a small proportion of stands undergo succession at any one time. Positive neighborhood effects are common in temperate and boreal zones, whereas negative effects are more common in tropical climates. Landscapes with positive dynamics have alternate categories of dynamics

    2016-01-01

    David Herbert Lawrence is one of the most important and controversial writers. Sons and Lovers, one of .his most influential novels, is his first full-length and semi-autobiographical novel. This novel describes the growing process and the emotional experiences of a coal mine worker's son Paul. This paper takes Freud's psychoanalytic theory as the theoretical basis. By analyzing three different patterns of relationships among Paul and three women, including mother Morel, lover Miriam and mistress Clara, this paper finally comes to a conclusion that the real love should be based on the harmony of the personality structure and the unity of the body and the soul.

    1997-04-01

    The authors report on a father and son with frontal lobe epilepsy and symptoms of attention deficit hyperactivity disorder (ADHD). Attention deficit hyperactivity is a syndrome defined by criteria that include inattention, impulsive behavior, impaired concentration and motor restlessness. It does not require medical or neurobehavioral evaluation to determine an underlying etiology. The father is a 45-year-old man evaluated for possible ADHD. His referral came after the diagnosis of ADHD in his 6-year-old son who responded well to treatment with methylphenidate HCL. Neurobehavioral evaluation of the father suggested frontal lobe dysfunction. Magnetic resonance imaging and electroencephalography (EEG) were normal. Brain 99mTc HMPAO single-photon emission computed tomography (SPECT) revealed left orbitofrontal hypoperfusion. Additional history from his wife revealed episodic symptoms suggestive of nonconvulsive epilepsy that included nonresponsive staring, complex automatic behavior, and amnesic lacunas. Treatment of the father with carbmazepine produced dramatic improvement. Subsequent evaluation of his son, currently on maintenance treatment with methylphenidate HCL for ADHD, elicited a history consistent with atonic and simple motor partial epilepsy. The son's brain SPECT revealed bilateral orbitofrontal hypoperfusion defects. Attention deficit hyperactivity disorder is a syndrome that may be caused by frontal lobe lesions or epilepsy. In the setting of possible ADHD, neurological evaluation is warranted. Although overreliance on structural imaging or EEG in such an evaluation must be discouraged, brain SPECT may be useful to evaluate patients with symptoms of attention disorders for frontal epilepsy.

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

    Science.gov (United States)

    Shaw, Jon A

    2013-01-01

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

    Familial achalasia most often has been recorded in siblings, and only rarely (twice previously) in a parent and offspring. This report concerns a third case of achalasia in a parent and offspring (mother and son). Clinical and radiographic features of the esophageal achalasia are presented. The possibility that genetic factors may play a role in the etiology of this disorder is discussed.

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

    Sex allocation theory predicts that parents are selected to bias their progeny sex ratio (SR) toward the sex that will benefit the most from parental quality. Because parental quality may differentially affect survival of sons and daughters, a pivotal test of the adaptive value of SR adjustment is whether parents overproduce offspring of the sex that accrues larger fitness advantages from high parental quality. However, this crucial test of the long-term fitness consequences of sex allocation decisions has seldom been performed. In this study of the barn swallow (Hirundo rustica), we showed a positive correlation between the proportion of sons and maternal annual survival. We then experimentally demonstrated that this association did not depend on the differential costs of rearing offspring of either sex. Finally, we showed that maternal lifespan positively predicted lifespan of sons but not of daughters. Because in barn swallows lifespan is a strong determinant of lifetime reproductive success, the results suggest that mothers overproduce offspring of the sex that benefits the most from maternal quality. Hence, irrespective of mechanisms causing the SR bias and mother-son covariation in lifespan, we provide strong evidence that sex allocation decisions of mothers can highly impact on their lifetime fitness.

  17. Forests vanish as population expands.

    Madagascar's forests have been reduced to a narrowing strip along the eastern escarpment. Of the original forest cover of 11.2 million hectares, only 7.6 million remained in 1950. Today this has been halved to 3.8 million hectares--which means the habitat for the island's unique wildlife has been halved, in just 40 years. Every year some 3% of the remaining forest is cleared, almost all of that to provide land for populations expanding at 3.2% a year. The story of 1 village, Ambodiaviavy, near Ranomafana, shows the process at work. 50 years ago the whole area was dense forest. 8 families, 32 people in all, came here in 1947, after French colonials burned down their old village. At first the new settlers farmed only the valley bottoms, easily irrigated by the stream running down from the hilltops. There was no shortage of land. Each family took as much as they were capable of working. Over the next 43 years, the village population swelled 10 times over, to 320, and the number of families grew to 36. Natural growth was supplemented by immigration from the overcrowded plateau, where all cultivable land was occupied. The valley bottom lands had filled up completely by the 1950s. New couples started to clear forest on the sloping valley sides. They moved gradually uphill until today, they are 2/3 of the way to the hilltops. There was a parallel decline in the size of each family's paddy holding--also fueled by population growth. When children marry, parents have to subdivide their own land and give them a plot. So holding in the irrigated valley bottoms have dwindled. Today only a few are big enough to feed a family. The more children in a family, the smaller their share as adults will be. The village chief lives in a small mud hut, looking out over a valley he once owned entirely. Since then he has had 10 children, and given parcels away to each. Though he is the wealthiest man in the village in cattle, his son are among the poorest. They 1/2 a hectare of paddy each

    River Son, draining diverse lithologies in the subtropical climate of the peninsular sub-basin of the Ganga basin, is one of the major tributaries of the Ganga River. The chemistry of major ions in the surface water of the Son River was studied in detail to determine various source(s) and processes controlling its water chemistry, seasonal and spatial variations in water chemistry, dissolved fluxes and chemical denudation rate (CDR). The study shows that Ca2+, Mg2+ and HCO$^{-}_{3}$ are major ionic species in the river water. Most of the measured parameters exhibit a relatively lower concentration in the post-monsoon as compared to pre-monsoon season. The water chemistry highlights the influence of continental weathering aided by secondary contributions from ground water, saline/alkaline soils and anthropogenic activities in the catchment. Results also reflect the dominance of carbonate weathering over silicate weathering in controlling water composition. The Son River delivers about 4.2 million tons of dissolved loads annually to the Ganga River, which accounts for ∼6% of the total annual load carried by the Ganga River to the Bay of Bengal. The average CDR of the Son River is 59.5 tons km−2 yr−1, which is less than the reported 72 tons km−2 yr−1 of the Ganga River and higher than the global average of 36 tons km−2 yr−1. The water chemistry for the pre-monsoon and post-monsoon periods shows a strong seasonal control on solute flux and CDR values. The water chemistry indicates that the Son River water is good to excellent in quality for irrigation and also suitable for drinking purposes.

  1. Instabilities of Spherical Solutions with Multiple Galileons and SO(N) Symmetry

    CERN Document Server

    Andrews, Melinda; Khoury, Justin; Trodden, Mark

    2010-01-01

    The 4-dimensional effective theory arising from an induced gravity action for a co-dimension greater than one brane consists of multiple galileon fields pi^I, I=1...N, invariant under separate Galilean transformations for each scalar, and under an internal SO(N) symmetry. We study the viability of such models by examining spherically symmetric solutions. We find that for general, non-derivative couplings to matter invariant under the internal symmetry, such solutions exist and exhibit a Vainshtein screening effect. By studying perturbations about such solutions, we find both an inevitable gradient instability and fluctuations propagating at superluminal speeds. These findings suggest that more general, derivative couplings to matter are required for the viability of SO(N) galileon theories.

  3. Planning a Career in Engineering: Parental Effects on Sons and Daughters

    Directory of Open Access Journals (Sweden)

    Jerry A. Jacobs

    2017-01-01

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

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

    2015-01-01

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

    Objective To study son preferences and the contraceptive knowledge, attitude and practices of Indian Male Subjects & Methods The data was obtained through a semi-structured interview schedule caried out in 2 687 married men at Mumbai City, India in 1999.Results About 80% of men felt two children as their ideal family size, while 82%desired two children i.e. one son and one daughter. 8. 2% of men had strong prefer ence for two or more sons because of family lineage, old age support and to support each other.23. 1% of the couples had used contraceptives in the past, 48% of couples were not using any contraceptive method at the time of survey. Male participation in spacing contraceptive methods was 23% i.e. condom 21.9% and withdrawal 1.1%. Though awareness (99. 9% ) and knowledge (95. 2% ) of condom was high, only 42. 8% of subjects knew use the correct of the method. Only 2. 4% of them thought about accept ing vasectomy, while others reported various misconception.Conclusion This study suggests a pressing need for effective intervention strategies,both at the community level and the clinic level, backed with efficient motivation, coun seling and provision of quality services in urban areas.

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

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

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

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

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

    Directory of Open Access Journals (Sweden)

    Peter J. Tellegen

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

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

    2016-12-01

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

    Tropical forests are among the most species-rich ecosystems on the planet. Some authors argue that predictions of a tropical forest extinction crisis based on analyses of deforestation rates are overly pessimistic since they do not take account of future agricultural abandonment as a result of rural-urban migration and subsequent secondary regrowth. Even if such regrowth occurs, it is crucial to consider threats to species that are not directly correlated with area of forest cover. Hunting is an insidious but significant driver of tropical forest defaunation, risking cascading changes in forest plant and animal composition. Ineffective legislation and enforcement along with a failure of decision makers to address the threats of hunting is fanning the fire of a tropical forest extinction crisis. If tropical forest ecosystems are to survive, the threat of unsustainable hunting must be adequately addressed now.

    This study was designed to examine the paternal determinants of male adolescent marijuana use in the context of the mother-son and parental relationships. In addition, parental factors affecting experimental vs regular use of marijuana were examined. Two hundred forty-six male college students and their fathers were administered written questionnaires. Results indicated that the father's personality attributes and socialization techniques are associated with the son's use of marijuana despite control on the mother-son relationship. Fathers of marijuana users score higher on measures of psychopathology and unconventionality, and are less likely to have established close relationships with their sons. In addition, marijuana users more than nonusers have unaffectionate mothers and parents with less harmonious marital relations. Also of importance were interactions within the family system. The significance of these second-order effects highlights the importance of examining the father-son relation in the context of mother-son and parental interactions.

  3. The Black Rock Forest Consortium: A narrative

    Science.gov (United States)

    Buzzetto-More, Nicole Antoinette

    The Black Rock Forest is a 3,785-acre wilderness area whose richly forested landscape represents the splendor of the Hudson Valley Region of New York State. Although originally intended to become the home of wealthy banker James Stillman, it was his son Ernest whose love of conservation caused him to embrace the then new and revolutionary practice of sustainable forestry and establish Black Rock in 1928. Due to Ernest Stillman's foresight, the property was protected from development and bequeathed to Harvard University following his death for the establishment of an experimental forest. The modern environmental movement in America began when the Black Rock Forest was threatened with development by Consolidated Edison, and the people of the surrounding community banded together, battling tirelessly for over 17 years to stop the degradation of this historic forest. The outcome of this crusade marked a hallmark win for the environment leaving an illustrious and inveterate legacy. The campaign resulted in the watershed legislation the National Environmental Policy Act, the formation of several environmental advocacy groups, the creation of the Council on Environmental Quality of the Executive Office of the President, as well as set a precedent for communities to initiate and win cases against major corporations in order to safeguard natural resources. In the midst of the controversy it became apparent that alternative futures for the Forest needed to be explored. As a result of a committee report and one man's vision, the idea emerged to create a consortium that would purchase and steward the Forest. With a formation that took nearly fifteen years, the Black Rock Forest Consortium was formed, a unique amalgamation of K--12 public and private schools, colleges and universities, and science and cultural centers that successfully collaborate to enhance scientific research, environmental conservation, and education. The Consortium works to bridge the gaps between learners

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

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

    The 16th century French anatomist Guillaume Rondelet will be remembered as a great naturalist and a founder of ichthyology. Little known to most is that Rondelet was a proficient anatomist and contemporary to Vesalius and in fact, both studied anatomy under Johannes Guinter. Even less known is that he established the first dissecting theatre at Montpellier and it was here that he would dissect his infant son in an attempt to identify the cause of death. In this article, we review the life and contributions to anatomy of Rondelet.

    The chiral ring of classical supersymmetric Yang-Mills theory with gauge group Sp(N) or SO(N) is computed, extending previous work (of Cachazo, Douglas, Seiberg, and the author)for SU(N). The result is that, as has been conjectured, the ring is generated by the usualglueball superfield S ~ Tr WαWα, with the relation Sh = 0, h being the dual Coxeter number.Though this proposition has important implications for the behavior of the quantum theory,the statement and (for the most part) the proofs amount to assertions about Lie groups withno direct reference to gauge theory.

    Non-Abelian BPS vortices in SO(N) x U(1) and USp(2N) x U(1) gauge theories are constructed in maximally color-flavor locked vacua. We study in detail their moduli and transformation properties under the exact symmetry of the system. Our results generalize non-trivially those found earlier in supersymmetric U(N) gauge theories. The structure of the moduli spaces turns out in fact to be considerably richer here than what was found in the U(N) theories. We find that vortices are generally of the semi-local type, with power-like tails of profile functions.

    2014-03-01

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

    Full Text Available Anaptyxis is a sound appearing that is not found in the original structure of the word. There are three types of anaptyxis: prothesis, epenthesis and epithesis. Epithesis is a vowel or consonant appearing at the end of a word which is not found in the original structure of it. Although, there isn’t not so much example, both vowel and consonant reproduction is seen even in the last sound of the word; but the derivative sound isn’t the same, standard in the whole dialects and accents. Nevertheless some derivative sounds have an intense in a specific region, they aren’t seen in the other areas or has rare example. In this study, the epithesis in the loan words in Turkish will be emphasized. Bir kelimede aslında bulunmayan bir sesin sonradan ortaya çıkmasına ses türemesi denir. Ses türemesinin üç çeşidi vardır: ön türeme, iç türeme, son türeme. Son türeme, kelimenin aslında bulunmayan bir ünlü veya ünsüzün kelime sonunda belirmesidir.

    2004-04-01

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

    2002-01-01

    It is shown that the correlations between two qubits selected from a trio prepared in a W state violate the Clauser-Horne-Shimony-Holt inequality more than the correlations between two qubits in any quantum state. Such a violation beyond Cirel'son's bound is smaller than the one achieved by two qubits selected from a trio in a Greenberger-Horne-Zeilinger state [A. Cabello, Phys. Rev. Lett. 88, 060403 (2002)]. However, it has the advantage that all local observers can know from their own measurements whether their qubits belongs or not to the selected pair.

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

    2009-10-01

    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.

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

    Science.gov (United States)

    Miller, R J; Boon, S D

    2000-01-01

    This study explored the possibility that changes in feelings of trust for mother are associated with gay males' decisions to disclose (or withhold) their sexual orientation in their mother-son relationships. Fifty gay and bisexual males completed a questionnaire about their coming out experiences in the context of their relationships with their mothers. As part of this questionnaire, they completed a retrospective graphical trust history task that involved plotting the degree of trust they felt for their mothers over time and across important events (such as disclosure). Results are discussed in terms of gay men's expectations about their mothers' responses to disclosure, the evidence for stability versus change in their memories regarding the nature of their feelings of maternal trust over time, the complexity of the trust histories participants drew, similarity between disclosers and non-disclosers in the shape of their trust curves, and the types of events and experiences that constituted the timeline or "plot" in the stories participants told about their mother-son relationships. This study offers the first empirical evidence to support speculations linking disclosure of sexual orientation to the climate of trust that exists in the relationship between discloser and target (e.g., Holtzen, Kenny & Mahalik, 1995).

  17. Symbolism of the Shadows in Son of Man by Roa Bastos

    Institute of Scientific and Technical Information of China (English)

    Patricia G. Montenegro

    2015-01-01

    In his novel Son of Man, Augusto Roa Bastos uses images and symbols of shadows to represent the ramifications ofthe Paraguayan Dr. Jose Rodriguez de Francia's dictatorship. Rodriguez de Francia's legacy, which begins duringthe postcolonial years and extends well into the 20th century, resonates in the novel in soeio-political structures andcharacters' ideologies and behaviors. It allows for plantation owners to enslave workers and their families; itconfines and oppresses people through unfounded legends and myths; and among other things, it creates a falseidea of purpose and patriotism in the Chaco War (1932-1935), which in the end lets down the soldiers. Tocounteract these deleterious social conditions, Roa Bastos creates surreal characters, such as a fantastic helper whoaids plantation workers to escape dehumanizing situations. Roa Bastos also narrates how the people in Itapr, asmall town, make an idol of a Christ statue carved by one of their own. However, when the two Goiburfl brothersreplace the statue by crucifying their sister's rapist, the people's myth is destroyed. Likewise, Roa Bastos availshimself of Christian and Catholic concepts and symbols to transpose them into a humanistic ideology so as toconvey hope to his people through a new perspective. In this way, a new Annunciation takes place when the son ofa raped woman is born. In the end, Roa Bastos lets the course of these warped transpositions take their logicaldenouement: In the absence of a purpose beyond an earthly existence, death becomes the narrator's option.

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

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

    In Thailand, Mae Hong Son Province is highly endemic for malaria. Knowing this, the local Health Department has introduced a program to educate local residents about the risk factors, in particular the dangers and symptoms of malaria. This study was conducted to evaluate these efforts, by determining the number of malaria infections in a segment of the population, and also by testing for enterobiasis among a group of its children. Two villages in Mae Hong Son Province were chosen for this purpose with a combined population of about 300. Of these, 195 were screened for malaria. Two subjects were diagnosed positive for malaria by microscopy. One of these two villages was chosen to screen for Enterobius vermicularis infection in children as well. Out of 69 stool samples, five (7%) showed infection with E. vermicularis: three with a low number of eggs (1-50), and two with a high number of eggs (>100). Compared with infection rates in similar studies, the results of this study indicate that the Health Department's efforts are meeting with relative success. The low prevalence of infection indicates that the villagers are using the information they have received to help combat infection.

  2. ‘Too many girls, too much dowry’: son preference and daughter aversion in rural Tamil Nadu, India

    Science.gov (United States)

    DIAMOND-SMITH, NADIA; LUKE, NANCY; MCGARVEY, STEPHEN

    2013-01-01

    The southern Indian state of Tamil Nadu has experienced a dramatic decline in fertility, accompanied by a trend of increased son preference. This paper reports on findings from qualitative interviews with women in rural villages about their fertility decision-making. Specifically addressed are the reasons behind increasing son preference and the consequences of this change. Findings suggest that daughter aversion, fuelled primarily by the perceived economic burden of daughters due to the proliferation of dowry, is playing a larger role in fertility decision-making than son preference. The desire for a son is often trumped by the worry over having many daughters. Women use various means of controlling the sex of their children, which in this study appear to be primarily female infanticide. It is important to distinguish between son preference and daughter aversion and to examine repercussions of low fertility within this setting. PMID:18821352

  3. [Separation in the mother-son relationship: an adolescent problem in Rainer Maria Rilke's story "Silent accompaniment"].

    Wittstruck, W

    1995-01-01

    The story 'Quiet Accompanying' by Ranier Maria Rilke's early work is of special interest for research on adolescence. The story is a literary contribution to the separation conflict of parents and their maturing children, especially the separation crisis in the mother-son relationship. The story's suspense is derived from the son's desire to begin a new phase in life and his experience of being powerless regarding his ties to his family. Thereby the adolescent crisis of the male main character is indirectly picked out as the main theme in the description of the mother's separation crisis. In the mother's 'dream' where the departure for a sunday excursion is described, an image of the son's adolescence with the components search for identity, separation and closeness develops. The son's efforts finally fail because mother and son are captured in their relationship characterized by conflicts and fears.

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

    Science.gov (United States)

    Allen, Holly

    2017-03-01

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

  9. Mother-son relationship as a risk factor for depressive symptoms among methamphetamine users.

    Science.gov (United States)

    Semple, Shirley J; Strathdee, Steffanie A; Zians, Jim; Patterson, Thomas L

    2012-02-01

    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.

    Several refinements are made in a theory which starts with a Planck-scale statistical picture and ends with supersymmetry and a coupling of fundamental fermions and bosons to SO(N) gauge fields. In particular, more satisfactory treatments are given for (1) the transformation from the initial Euclidean form of the path integral for fermionic fields to the usual Lorentzian form, (2) the corresponding transformation for bosonic fields (which is much less straightforward), (3) the transformation from an initial primitive supersymmetry to the final standard form (containing, e.g., scalar sfermions and their auxiliary fields), (4) the initial statistical picture, and (5) the transformation to an action which is invariant under general coordinate transformations.

But the right side of his body slumps like someone who has had a stroke. Once right handed, he now uses only his left hand. At 15, he knocked his eyes off their parallel tracks by slamming his temple into the corner of a wooden post. One eye looks straight ahead while the other looks up and to the side. Both optic nerves are damaged. All the damage is self-inflicted. He has been banging and punching his head since babyhood. © 2017 Wiley Periodicals, Inc.

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

    Forest fire detection is a very important issue in the pre-suppression process. Timely detection allows the suppression units to reach the fire in its initial stages and this will reduce the suppression costs considerably. The autonomous forest fire detection principle is based on temporal contrast

    Background Animal studies have demonstrated that timing of pubertal onset can be altered by prenatal exposure to dioxins or polychlorinated biphenyls (PCBs), but studies of human populations have been quite limited. Methods We assessed the association between maternal serum concentrations of dioxins and PCBs and the sons’ age of pubertal onset in a prospective cohort of 489 mother–son pairs from Chapaevsk, Russia, a town contaminated with these chemicals during past industrial activity. The boys were recruited at ages 8 to 9 years, and 4 years of annual follow-up data were included in the analysis. Serum samples were collected at enrollment from both mothers and sons for measurement of dioxin and PCB concentrations using high-resolution mass spectrometry. The sons’ pubertal onset—defined as pubertal stage 2 or higher for genitalia (G) or pubic hair (P), or testicular volume >3 mL—was assessed annually by the same physician. Results In multivariate Cox models, elevated maternal serum PCBs were associated with earlier pubertal onset defined by stage G2 or higher (4th quartile hazard ratio = 1.7 [95% confidence interval = 1.1– 2.5]), but not for stage P2 or higher or for testicular volume >3 mL. Maternal serum concentrations of dioxin toxic equivalents were not consistently associated with the sons’ pubertal onset, although a dose-related delay in pubertal onset (only for G2 or higher) was seen among boys who breast-fed for 6 months or more. Conclusions Maternal PCB serum concentrations measured 8 or 9 years after sons’ births—which may reflect sons’ prenatal and early-life exposures—were associated with acceleration in some, but not all, measures of pubertal onset.

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

    2005-12-16

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

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

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

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

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

    The potential influence of diversity on ecosystem structure and function remains a topic of significant debate, especially for tropical forests where diversity can range widely. We used Center for Tropical Forest Science (CTFS) methodology to establish forest dynamics plots in montane wet forest and lowland dry forest on Hawai'i Island. We compared the species diversity, tree density, basal area, biomass, and size class distributions between the two forest types. We then examined these variables across tropical forests within the CTFS network. Consistent with other island forests, the Hawai'i forests were characterized by low species richness and very high relative dominance. The two Hawai'i forests were floristically distinct, yet similar in species richness (15 vs. 21 species) and stem density (3078 vs. 3486/ha). While these forests were selected for their low invasive species cover relative to surrounding forests, both forests averaged 5->50% invasive species cover; ongoing removal will be necessary to reduce or prevent competitive impacts, especially from woody species. The montane wet forest had much larger trees, resulting in eightfold higher basal area and above-ground biomass. Across the CTFS network, the Hawaiian montane wet forest was similar to other tropical forests with respect to diameter distributions, density, and aboveground biomass, while the Hawai'i lowland dry forest was similar in density to tropical forests with much higher diversity. These findings suggest that forest structural variables can be similar across tropical forests independently of species richness. The inclusion of low-diversity Pacific Island forests in the CTFS network provides an ∼80-fold range in species richness (15-1182 species), six-fold variation in mean annual rainfall (835-5272 mm yr(-1)) and 1.8-fold variation in mean annual temperature (16.0-28.4°C). Thus, the Hawaiian forest plots expand the global forest plot network to enable testing of ecological theory for

Protected areas cover 217.2 million ha (19.6%) of the world's humid tropical forests and contain c. 70.3 petagrams of carbon (Pg C) in biomass and soil to 1 m depth. Between 2000 and 2005, we estimate...... that 1.75 million ha of forest were lost from protected areas in humid tropical forests, causing the emission of 0.25-0.33 Pg C. Protected areas lost about half as much carbon as the same area of unprotected forest. We estimate that the reduction of these carbon emissions from ongoing deforestation...... in protected sites in humid tropical forests could be valued at USD 6,200-7,400 million depending on the land use after clearance. This is >1.5 times the estimated spending on protected area management in these regions. Improving management of protected areas to retain forest cover better may be an important...

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

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

  18. The Challenge of Forest Diagnostics

    Full Text Available Ecologists and practitioners have conventionally used forest plots or transects for monitoring changes in attributes of forest condition over time. However, given the difficulty in collecting such data, conservation practitioners frequently rely on the judgment of foresters and forest users for evaluating changes. These methods are rarely compared. We use a dataset of 53 forests in five countries to compare assessments of forest change from forest plots, and forester and user evaluations of changes in forest density. We find that user assessments of changes in tree density are strongly and significantly related to assessments of change derived from statistical analyses of randomly distributed forest plots. User assessments of change in density at the shrub/sapling level also relate to assessments derived from statistical evaluations of vegetation plots, but this relationship is not as strong and only weakly significant. Evaluations of change by professional foresters are much more difficult to acquire, and less reliable, as foresters are often not familiar with changes in specific local areas. Forester evaluations can instead better provide valid single-time comparisons of a forest with other areas in a similar ecological zone. Thus, in forests where local forest users are present, their evaluations can be used to provide reliable assessments of changes in tree density in the areas they access. However, assessments of spatially heterogeneous patterns of human disturbance and regeneration at the shrub/sapling level are likely to require supplemental vegetation analysis.

    This article examines how the sex composition of women's current children at the start of a pregnancy interval influences both fertility desires and the full range of reproductive actions women may take to realize them, including temporary contraception, abortion and sterilization, in Madhya Pradesh, India, where popular notions of ideal family size and sex composition are dominated by son preference. The analysis is conducted using a dataset of 9127 individual pregnancy intervals from a 2002 statewide representative survey of 2444 women aged 15-39 with at least one child. The results indicate that women's preferences go beyond a singular preference for male children, with the preferred composition of children being two boys and one girl. Women with this composition are 90% less likely to report having wanted another pregnancy (OR 0.097, p < 0.01) relative to those with two girls. These preferences have significant implications for reproductive actions. While sex composition has no statistically significant effect on the use of temporary contraception, those with the preferred sex composition are twice as likely to attempt abortion (OR 2.436, p < 0.01) and twelve times more likely to be sterilized (OR 12.297, p < 0.01) relative to those with two girls only.

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

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

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

    With the development of mobile internet and multi-media service,advanced techniques need to be applied in wireless network to improve user experience.Long term evolution (LTE) systems,which can offer up to 100Mbps downlink date rates,have been deployed in USA and Korea.However,because plenty of complex physical layer algorithms are utilized,network planning and optimization become heavy burdens for LTE network operators.Self-organizing network (SON) is a promising method to overcome this problem by automatically selecting and adjusting key parameters in LTE systems.In this paper,we present a dynamic adjusting algorithm to improve both handover and load balancing performance by introducing a weighted co-satisfaction factor (CSF).Analysis and system level simulation are conducted to exhibit the performance improvement of the proposed scheme.Results show that the proposed method outperforms the conventional solutions in terms of the network handover success ratio and load balancing gains significantly.

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

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

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

    Tropical rainforests store enormous amounts of carbon, the protection of which represents a vital component of efforts to mitigate global climate change. Currently, tropical forest conservation, science, policies, and climate mitigation actions focus predominantly on reducing carbon emissions from deforestation alone. However, every year vast areas of the humid tropics are disturbed by selective logging, understory fires, and habitat fragmentation. There is an urgent need to understand the effect of such disturbances on carbon stocks, and how stocks in disturbed forests compare to those found in undisturbed primary forests as well as in regenerating secondary forests. Here, we present the results of the largest field study to date on the impacts of human disturbances on above and belowground carbon stocks in tropical forests. Live vegetation, the largest carbon pool, was extremely sensitive to disturbance: forests that experienced both selective logging and understory fires stored, on average, 40% less aboveground carbon than undisturbed forests and were structurally similar to secondary forests. Edge effects also played an important role in explaining variability in aboveground carbon stocks of disturbed forests. Results indicate a potential rapid recovery of the dead wood and litter carbon pools, while soil stocks (0-30 cm) appeared to be resistant to the effects of logging and fire. Carbon loss and subsequent emissions due to human disturbances remain largely unaccounted for in greenhouse gas inventories, but by comparing our estimates of depleted carbon stocks in disturbed forests with Brazilian government assessments of the total forest area annually disturbed in the Amazon, we show that these emissions could represent up to 40% of the carbon loss from deforestation in the region. We conclude that conservation programs aiming to ensure the long-term permanence of forest carbon stocks, such as REDD+, will remain limited in their success unless they effectively

    This paper described the role that disturbances play in maintaining the ecological integrity of Canadian boreal forests. Potential adaptation options to address the challenges that these disturbances present were also examined. Many forest ecosystems need fire for regeneration, while other forests rely on a cool, wet disintegration process driven by insects and commensal fungi feeding on trees to effect renewal. While there are characteristic natural, temporal and spatial patterns to these disturbances, recent work has demonstrated that the disturbances are being perturbed by climatic change that has been compounded by anthropogenic disturbances in forests. Fire influences species composition and age structure, regulates forest insects and diseases, affects nutrient cycling and energy fluxes, and maintains the productivity of different habitats. Longer fire seasons as a result of climatic change will lead to higher intensity fires that may more easily evade initial attacks and become problematic. Fire regimes elevated beyond the range of natural variation will have a dramatic effect on the regional distribution and functioning of forest ecosystems and pose a threat to the safety and prosperity of people. While it was acknowledged that if insect outbreaks were to be controlled on the entire forest estate, the productivity represented by dead wood would be lost, it was suggested that insects such as the forest tent caterpillar and the spruce bud worm may also pose a greater threat as the climate gets warmer and drier. Together with fungal associates, saproxylic arthropods are active in nutrient cycling and ultimately determine the fertility of forest sites. It was suggested that the production of an age class structure and forest mosaic would render the forest landscape less vulnerable to the more negative aspects of climate change on vegetation response. It was concluded that novel management design paradigms are needed to successfully reduce the risk from threats

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

    Directory of Open Access Journals (Sweden)

    Bubalo Đorđe

    2009-01-01

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

    Full Text Available To understand drought adaptation practices, we compared two groups of sugarcane growers in Thanh Cong commune, Thach Thanh district, Thanh Hoa province in Vietnam. Results of this study point out that farmers, depending on their preferred type of market channels, reacted differently to the impacts of drought. Contractual farmers paid more attention to the impact on sugarcane tillering and sugar content, while market-oriented farmers paid more attention to sugarcane colour, as this trait directly determined the market price on the cane that is either consumed as cane or as juice. In responding to water stress in the growing season, the open market-oriented farmers showed more flexibility in changing their cropping calendar. They were also more willing to invest in enhancing the water management system and in providing organic fertilizer than the contractual farmers. On the other hand, the low cane price and the harvesting date set in contract by the processing company lessened the contractual farmers' flexibility in investing in water management technologies; thus, hampering their adaptation to drought.

    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. 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). 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. 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. 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. 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.

    2012-09-01

    Full Text Available The introduction of Airborne Laser Scanning (ALS to forests has been revolutionary during the last decade. This development was facilitated by combining earlier ranging lidar discoveries [1–5], with experience obtained from full-waveform ranging radar [6,7] to new airborne laser scanning systems which had components such as a GNSS receiver (Global Navigation Satellite System, IMU (Inertial Measurement Unit and a scanning mechanism. Since the first commercial ALS in 1994, new ALS-based forest inventory approaches have been reported feasible for operational activities [8–12]. ALS is currently operationally applied for stand level forest inventories, for example, in Nordic countries. In Finland alone, the adoption of ALS for forest data collection has led to an annual savings of around 20 M€/year, and the work is mainly done by companies instead of governmental organizations. In spite of the long implementation times and there being a limited tradition of making changes in the forest sector, laser scanning was commercially and operationally applied after about only one decade of research. When analyzing high-ranked journal papers from ISI Web of Science, the topic of laser scanning of forests has been the driving force for the whole laser scanning research society over the last decade. Thus, the topic “laser scanning in forests” has provided a significant industrial, societal and scientific impact. [...

  9. A Possible Link Between the Pubertal Growth of Girls and Prostate Cancer in Their Sons

    Objectives Among women attending antenatal clinics during 1934–1944 a large intercristal diameter, the maximum distance between the pelvic iliac crests, was associated with a raised incidence of breast and ovarian cancer in the daughters in later life. At puberty, the intercristal diameter of girls enlarges rapidly under the influence of estrogen. We speculated that high maternal estrogen concentrations during pregnancy initiate hormonal cancers in their daughters. Here, we examine the association between the mothers’ intercristal diameters and prostate cancer in their sons. Methods Using the national cancer registry we identified 221 cases of prostate cancer among 6,975 men born during 1934–1944 in Helsinki, Finland. Four thousand four hundred and one of these men had their mother’s bony pelvic measurements recorded: there were 149 cases among them. Results Hazard ratios for prostate cancer rose as the mother’s intercristal diameter increased; but this association was restricted to men who were born before 40 weeks of gestation. Among these men the hazard ratio was 1.27 (95% CI 1.09–1.48; P = 0.002). The hazard ratio was 2.2 (1.3–3.7; P < 0.001) in men whose mothers weighed more than 80 kg in late pregnancy compared with those whose mothers weighed 60 kg or less. Conclusions These findings are consistent with a conceptual framework for the origins of hormonally dependent cancers that invokes exposure of embryonic tissue to maternal sex hormones followed by resetting of the fetal hypothalamic-gonadotropin axis in late gestation. We hypothesize that compensatory prepubertal growth among girls is associated with hormonal cancers in the next generation. PMID:22287160

    2012-06-01

    Full Text Available In the recent years, there has been considerable interest in the realization of high speed, small-size and low-power consuming devices and systems. As a consequence, the search for new principle of operation of the small-size, high speed and low-power device is becoming more and more important. In our earlier paper, it has been established that SON technology, not only improve the dc performance with reduce a short-channel effect and threshold voltage, it also improves the frequency response due to improvement in conductance and reduced parasitic effect. Further, it is already in our knowledge that SCEs are suppressed in dual material gate MOSFETs because of the perceivable step in the surface-potential profile, which screens the drain potential. The concept of dual material gate has been applied to SON MOSFETs structure and the features exhibited by resulting new SON structure has been examined for the first time by developing an analytical model and the result agree well with the MEDICI simulation values. In order to substantiate the merits of the proposed SON MOSFETs, a MOS Inverter is realized using the SON MOSFETs and its performance is investigated as an aid to the high-speed, ultra-dense and low-power circuit related work.

    2010-07-01

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

    Forests play a major role in hydrology. Not only by immediate control of soil moisture and streamflow, but also by regulating climate through evaporation (i.e., transpiration, interception, and soil evaporation). The process of evaporation travelling through the atmosphere and returning as precipitation on land is known as moisture recycling. Whether evaporation is recycled depends on wind direction and geography. Moisture recycling and forest change studies have primarily focused on either one region (e.g. the Amazon), or one biome type (e.g. tropical humid forests). We will advance this via a systematic global inter-comparison of forest change impacts on precipitation depending on both biome type and geographic location. The rainfall effects are studied for three contemporary forest changes: afforestation, deforestation, and replacement of mature forest by forest plantations. Furthermore, as there are indications in the literature that moisture recycling in some places intensifies during dry years, we will also compare the rainfall impacts of forest change between wet and dry years. We model forest change effects on evaporation using the global hydrological model STEAM and trace precipitation changes using the atmospheric moisture tracking scheme WAM-2layers. This research elucidates the role of geographical location of forest change driven modifications on rainfall as a function of the type of forest change and climatic conditions. These knowledge gains are important at a time of both rapid forest and climate change. Our conclusions nuance our understanding of how forests regulate climate and pinpoint hotspot regions for forest-rainfall coupling.

  15. Design of forest rent accounting

    2016-12-01

    Full Text Available The urgent task for the effective functioning of the national economy is the need to reflect income from the use of forest resources in accounting, which will allow management personnel to prove the effectiveness of environmental protection measures, to assess the amount of expenses taken during restoration and protection of forest resources. The study aims at identifying characteristics of forest rent to determine the amount and its reflection in the accounting for its management. The author understands a forest rent as the income received from the owner of forest resources. The above procedure for determining the amount of forest rent can be used to display it in the accounting. A forest rent is a type of business income, so for its reflection in the accounting it is proposed to open the analytical accounts to account 79 named «Financial results». To determine the amount of forest rent and its reflection in the accounting the author suggests the calculation form of a forest rent. In order to manage the size of a forest rent and expenses incurred to obtain it the author proposes to use the information from the developed report about the forest rent formation. The displaying forest rents in accounting will provide accurate and deep information to the management about the revenue and assets of a company. The rational use of forest resources and accounting reflection of a forest rent will strengthen control over the influence of human activity on natural resources and keep the conception of sustainable development.

  17. I-SonReb: an improved NDT method to evaluate the in situ strength of carbonated concrete

    Science.gov (United States)

    Breccolotti, Marco; Bonfigli, Massimo F.

    2015-10-01

    Concrete strength evaluated in situ by means of the conventional SonReb method can be highly overestimated in presence of carbonation. This latter, in fact, is responsible for the physical and chemical alteration of the outer layer of concrete. As most of the existing concrete structures are subjected to carbonation, it is of high importance to overcome this problem. In this paper, an Improved SonReb method (I-SonReb) for carbonated concretes is proposed. It relies on the definition of a correction coefficient of the measured Rebound index as a function of the carbonated concrete cover thickness, an additional parameter to be measured during in situ testing campaigns. The usefulness of the method has been validated showing the improvement in the accuracy of concrete strength estimation from two sets of NDT experimental data collected from investigations on real structures.

    In recent work Bertram Kostant and Nolan Wallach ([KW1], [KW2]) have defined an interesting action of a simply connected Lie group $A$ isomorphic to \\mathbb{C}^{{n\\choose 2}} on gl(n) using a completely integrable system derived from Gelfand-Zeitlin theory. In this paper we show that an analogous action of \\mathbb{C}^{d} exists on the complex orthogonal Lie algebra so(n), where d is half the dimension of a regular adjoint orbit in so(n). In [KW1], Kostant and Wallach describe the orbits of $A$ on a certain Zariski open subset of regular semisimple elements in gl(n). We extend these results to the case of so(n). We also make brief mention of the author's results in [Col1], which describe all $A$-orbits of dimension {n\\choose 2} in gl(n).

  1. Por qué ser justos. ¿Son las normas de justicia sociales o morales?

    2013-08-01

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

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

    1995-11-01

    When the nations of the world signed and later ratified the United Nations Framework Convention on Climate Change (FCCC), they accepted the difficult challenge of stabilizing the composition of the atmosphere with respect to the greenhouse gases (GHGs). Success will require a reduction in both use of fossil fuels and rates of deforestation. Forests have a large enough influence on the atmosphere that one of the options for stabilizing the concentrations of GHGs in the atmosphere includes the use of forests as a carbon sink through reforestation of large areas. We identify in this paper the potential and the limitations of such projects.

    When the nations of the world signed and later ratified the United Nations Framework Convention on Climate Change (FCCC), they accepted the difficult challenge of stabilizing the composition of the atmosphere with respect to the greenhouse gases (GHGs). Success will require a reduction in both use of fossil fuels and rates of deforestation. Forests have a large enough influence on the atmosphere that one of the options for stabilizing the concentrations of GHGs in the atmosphere includes the use of forests as a carbon sink through reforestation of large areas. We identify in this paper the potential and the limitations of such projects. We discuss the implications of four approaches in management of forests globally: (i) continued deforestation, (ii) halting deforestation, (iii) net reforestation including agroforestry, and (iv) substituting the use of wood fuels for fossil fuels.

  2. Interpreting Sustainability for Urban Forests

    Directory of Open Access Journals (Sweden)

    Camilo Ordóñez

    2010-06-01

    Full Text Available Incisive interpretations of urban-forest sustainability are important in furthering our understanding of how to sustain the myriad values associated with urban forests. Our analysis of earlier interpretations reveals conceptual gaps. These interpretations are attached to restrictive definitions of a sustainable urban forest and limited to a rather mechanical view of maintaining the biophysical structure of trees. The probing of three conceptual domains (urban forest concepts, sustainable development, and sustainable forest management leads to a broader interpretation of urban-forest sustainability as the process of sustaining urban forest values through time and across space. We propose that values—and not services, benefits, functions or goods—is a superior concept to refer to what is to be sustained in and by an urban forest.

    Long-term monitoring of distributed, multiple plots is the key to quantify macroecological patterns and changes. Here we examine the evidence for concerted changes in the structure, dynamics and composition of old-growth Amazonian forests in the late twentieth century. In the 1980s and 1990s, mature forests gained biomass and underwent accelerated growth and dynamics, all consistent with a widespread, long-acting stimulation of growth. Because growth on average exceeded mortality, intact Amazonian forests have been a carbon sink. In the late twentieth century, biomass of trees of more than 10cm diameter increased by 0.62+/-0.23tCha-1yr-1 averaged across the basin. This implies a carbon sink in Neotropical old-growth forest of at least 0.49+/-0.18PgCyr-1. If other biomass and necromass components are also increased proportionally, then the old-growth forest sink here has been 0.79+/-0.29PgCyr-1, even before allowing for any gains in soil carbon stocks. This is approximately equal to the carbon emissions to the atmosphere by Amazon deforestation. There is also evidence for recent changes in Amazon biodiversity. In the future, the growth response of remaining old-growth mature Amazon forests will saturate, and these ecosystems may switch from sink to source driven by higher respiration (temperature), higher mortality (as outputs equilibrate to the growth inputs and periodic drought) or compositional change (disturbances). Any switch from carbon sink to source would have profound implications for global climate, biodiversity and human welfare, while the documented acceleration of tree growth and mortality may already be affecting the interactions among millions of species.

  11. Forest structure in low-diversity tropical forests: a study of Hawaiian wet and dry forests.

    Directory of Open Access Journals (Sweden)

    Rebecca Ostertag

    Full Text Available The potential influence of diversity on ecosystem structure and function remains a topic of significant debate, especially for tropical forests where diversity can range widely. We used Center for Tropical Forest Science (CTFS methodology to establish forest dynamics plots in montane wet forest and lowland dry forest on Hawai'i Island. We compared the species diversity, tree density, basal area, biomass, and size class distributions between the two forest types. We then examined these variables across tropical forests within the CTFS network. Consistent with other island forests, the Hawai'i forests were characterized by low species richness and very high relative dominance. The two Hawai'i forests were floristically distinct, yet similar in species richness (15 vs. 21 species and stem density (3078 vs. 3486/ha. While these forests were selected for their low invasive species cover relative to surrounding forests, both forests averaged 5->50% invasive species cover; ongoing removal will be necessary to reduce or prevent competitive impacts, especially from woody species. The montane wet forest had much larger trees, resulting in eightfold higher basal area and above-ground biomass. Across the CTFS network, the Hawaiian montane wet forest was similar to other tropical forests with respect to diameter distributions, density, and aboveground biomass, while the Hawai'i lowland dry forest was similar in density to tropical forests with much higher diversity. These findings suggest that forest structural variables can be similar across tropical forests independently of species richness. The inclusion of low-diversity Pacific Island forests in the CTFS network provides an ∼80-fold range in species richness (15-1182 species, six-fold variation in mean annual rainfall (835-5272 mm yr(-1 and 1.8-fold variation in mean annual temperature (16.0-28.4°C. Thus, the Hawaiian forest plots expand the global forest plot network to enable testing of ecological

    2011-01-01

    A generalized threshold voltage model based on two-dimensional Poisson analysis has been developed for SOI/SON MOSFETs.Different short channel field effects,such as fringing fields,junction-induced lateral fields and substrate fields,are carefully investigated,and the related drain-induced barrier-lowering effects are incorporated in the analytical threshold voltage model.Through analytical model-based simulation,the threshold voltage roll-off and subthreshold slope for both structures are compared for different operational and structural parameter variations.Results of analytical simulation are compared with the results of the ATLAS 2D physicsbased simulator for verification of the analytical model.The performance of an SON MOSFET is found to be significantly different from a conventional SOI MOSFET.The short channel effects are found to be reduced in an SON,thereby resulting in a lower threshold voltage roll-offand a smaller subthreshold slope.This type of analysis is quite useful to figure out the performance improvement of SON over SOI structures for next generation short channel MOS devices.

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

    Science.gov (United States)

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

    2014-12-01

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

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

    2016-02-01

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

  3. The Dynamics of Son Preference, Technology Diffusion, and Fertility Decline Underlying Distorted Sex Ratios at Birth: A Simulation Approach.

    Science.gov (United States)

    Kashyap, Ridhi; Villavicencio, Francisco

    2016-10-01

    We present a micro-founded simulation model that formalizes the "ready, willing, and able" framework, originally used to explain historical fertility decline, to the practice of prenatal sex selection. The model generates sex ratio at birth (SRB) distortions from the bottom up and attempts to quantify plausible levels, trends, and interactions of son preference, technology diffusion, and fertility decline that underpin SRB trajectories at the macro level. Calibrating our model for South Korea, we show how even as the proportion with a preference for sons was declining, SRB distortions emerged due to rapid diffusion of prenatal sex determination technology combined with small but growing propensities to abort at low birth parities. Simulations reveal that relatively low levels of son preference (about 20 % to 30 % wanting one son) can result in skewed SRB levels if technology diffuses early and steadily, and if fertility falls rapidly to encourage sex-selective abortion at low parities. Model sensitivity analysis highlights how the shape of sex ratio trajectories is particularly sensitive to the timing and speed of prenatal sex-determination technology diffusion. The maximum SRB levels reached in a population are influenced by how the readiness to abort rises as a function of the fertility decline.

  6. The forest biodiversity artery: towards forest management for saproxylic conservation

    Directory of Open Access Journals (Sweden)

    2016-04-01

    Full Text Available One of the objectives of forest conservation is the set aside of unharvested areas. However, the fragmentation and lack of connectivity of protected areas make the integration of conservation measures in productive forests essential. Strategies to integrate conservation of saproxylic biodiversity in forest management have been developed, but often considering only specific aspects or remaining preliminary otherwise. As the impact of climate change and anthropogenic stresses increases, the development and the synthesis of this approach is crucial. We reviewed the key literature on forest management for biodiversity conservation, integrating forest science perspective to provide a practical management framework. Our goal is to present a management framework that could contribute to the effective preservation of forest insect biodiversity at the landscape scale, without high economic efforts, and addressing the conflicts that still jeopardize sustainable forest management. The results of our review support the creation of micro-reserves inside productive forests, to support large reserves in landscape conservation strategies. Micro-reserves increase the resilience of forest ecosystems to anthropogenic disturbances, through the development of a heterogeneous structure, maximizing microhabitat availability. Modeling forest management and harvest on local natural disturbance would extend the benefits of spatio-temporal heterogeneity in productive forests. Variable retention harvest systems, applied at the landscape scale, are a feasible and adaptable strategy to preserve and increase biodiversity, safeguarding structural legacies such as senescent trees and deadwood inside the productive matrix. The operational shift, from the stand to the forest landscape, is fundamental to extend the benefits of conservation measures. The Forest Biodiversity Artery, composed by several micro-reserves or îlots de senescence, connected by corridors of habitat trees

In 0-10 cm soil layer, the pool sizes of SOC, SON, MBC, and MBN at test sites ranged in 354-1007 mg x kg(-1), 24-73 mg x kg(-1), 203-488 mg x kg(-1), and 24-65 mg x kg(-1), and the soil urease and asparaginase activities were 95-133 mg x kg(-1) x d(-1) and 58-113 mg x kg(-1) x d(-1), respectively. There were significant differences in the pool sizes of SOC, SON, MBC, and MBN and the asparaginase activity among the test sites, but no significant difference was observed in the urease activity. The pool sizes of SOC and SON were in the order of IV > CK > III > I > II, those of MBC and MBN were in the order of CK > IV > III > I > II, and asparaginase activity followed the order of IV > CK > III > II > I. With the increase of soil depth, the pool sizes of SOC, SON, MBC, and MBN and the activities of soil asparaginase and urease decreased. In 0-20 cm soil layer, the SOC, SON, MBC, MBN, total C, and total N were highly correlated with each other, soil asparaginase activity was highly correlated with SOC, SON, TSN, total C, total N, MBC, and MBN, and soil urease activity was highly correlated with SON, TSN, total C, MBC and MBN.

  10. Tropical Forest Gain and Interactions amongst Agents of Forest Change

    Directory of Open Access Journals (Sweden)

    Sean Sloan

    2016-02-01

    Full Text Available The tropical deforestation literature advocates multi-agent enquiry in recognition that key dynamics arise from inter-agent interactions. Studies of tropical forest-cover gain have lagged in this respect. This article explores the roles and key aspects of interactions shaping natural forest regeneration and active reforestation in Eastern Panama since 1990. It employs household surveys of agricultural landholders, interviews with community forest-restoration organisations, archival analysis of plantation reforestation interests, satellite image analysis of forest-cover change, and the consideration of State reforestation policies. Forest-cover gain reflected a convergence of interests and land-use trends amongst agents. Low social and economic costs of sustained interaction and organisation enabled extensive forest-cover gain, but low transaction costs did not. Corporate plantation reforestation rose to the fore of regional forest-cover gain via opportunistic land sales by ranchers and economic subsidies indicative of a State preference for autonomous, self-organising forest-cover gain. This reforestation follows a recent history of neoliberal frontier development in which State-backed loggers and ranchers similarly displaced agriculturalists. Community institutions, long neglected by the State, struggled to coordinate landholders and so effected far less forest-cover gain. National and international commitments to tropical forest restoration risk being similarly characterised as ineffective by a predominance of industrial plantation reforestation without greater State support for community forest management.

    Concern for long-term availability of nonrenewable resources has fostered proposals for substitution with renewable resources. Forest products could become the basis for materials substitution and production. Further feasibility studies are needed to determine the technical, economic, energy, and environmental aspects of substitution. (MR)

    Forests are complex and dynamic ecosystems comprising individual trees that can vary in both size and species. In comparison to other organisms, trees are relatively long lived (40-2000 years), quite plastic in terms of their morphology and ecological niche, and adapted to a wide variety of habitats, which can make predicting their behaviour exceedingly difficult....

    Dynamic global vegetation models (DGVMs) have shown that forest dynamics could dramatically alter the response of the global climate system to increased atmospheric carbon dioxide over the next century. But there is little agreement between different DGVMs, making forest dynamics one of the greatest sources of uncertainty in predicting future climate. DGVM predictions could be strengthened by integrating the ecological realities of biodiversity and height-structured competition for light, facilitated by recent advances in the mathematics of forest modeling, ecological understanding of diverse forest communities, and the availability of forest inventory data.

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

    We present a historical overview of forest concepts and definitions, linking these changes with distinct perspectives and management objectives. Policies dealing with a broad range of forest issues are often based on definitions created for the purpose of assessing global forest stocks, which do not distinguish between natural and planted forests or reforests, and which have not proved useful in assessing national and global rates of forest regrowth and restoration. Implementing and monitoring forest and landscape restoration requires additional approaches to defining and assessing forests that reveal the qualities and trajectories of forest patches in a spatially and temporally dynamic landscape matrix. New technologies and participatory assessment of forest states and trajectories offer the potential to operationalize such definitions. Purpose-built and contextualized definitions are needed to support policies that successfully protect, sustain, and regrow forests at national and global scales. We provide a framework to illustrate how different management objectives drive the relative importance of different aspects of forest state, dynamics, and landscape context.

    1999-01-01

    The age of secondary forests in the Amazon will become more critical with respect to the estimation of biomass and carbon budgets as tropical forest conversion continues. Multitemporal Thematic Mapper data were used to develop land cover histories for a 33,000 Square kM area near Ariquemes, Rondonia over a 7 year period from 1989-1995. The age of the secondary forest, a surrogate for the amount of biomass (or carbon) stored above-ground, was found to be unimportant in terms of biomass budget error rates in a forested TM scene which had undergone a 20% conversion to nonforest/agricultural cover types. In such a situation, the 80% of the scene still covered by primary forest accounted for over 98% of the scene biomass. The difference between secondary forest biomass estimates developed with and without age information were inconsequential relative to the estimate of biomass for the entire scene. However, in futuristic scenarios where all of the primary forest has been converted to agriculture and secondary forest (55% and 42% respectively), the ability to age secondary forest becomes critical. Depending on biomass accumulation rate assumptions, scene biomass budget errors on the order of -10% to +30% are likely if the age of the secondary forests are not taken into account. Single-date TM imagery cannot be used to accurately age secondary forests into single-year classes. A neural network utilizing TM band 2 and three TM spectral-texture measures (bands 3 and 5) predicted secondary forest age over a range of 0-7 years with an RMSE of 1.59 years and an R(Squared) (sub actual vs predicted) = 0.37. A proposal is made, based on a literature review, to use satellite imagery to identify general secondary forest age groups which, within group, exhibit relatively constant biomass accumulation rates.

    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.

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

    Drawing on ecological and gender socialization perspectives, this study examined mothers’ and fathers’ relationships with young adolescents, exploring differences between mothers and fathers, for sons versus daughters, and as a function of parents’ division of paid labor. Mexican immigrant families (N = 162) participated in home interviews and seven nightly phone calls. Findings revealed that mothers reported higher levels of acceptance toward adolescents and greater knowledge of adolescents’ daily activities than did fathers, and mothers spent more time with daughters than with sons. Linkages between parent-adolescent relationship qualities and youth adjustment were moderated by adolescent gender and parents’ division of paid labor. Findings revealed, for example, stronger associations between parent–adolescent relationship qualities and youth adjustment for girls than for boys. PMID:19779582

    2010-01-01

    The expectation value of Wilson loop operators in three-dimensional SO(N) Chern-Simons gauge theory gives a known knot invariant: the Kauffman polynomial. Here this result is derived, at the first order, via a simple variational method. With the same procedure the skein relation for Sp(N) are also obtained. Jones polynomial arises as special cases: Sp(2), SO(-2) and SL(2,R). These results are confirmed and extended up to the second order, by means of perturbation theory, which moreover let us establish a duality relation between SO(+/-N) and Sp(-/+N) invariants. A correspondence between the firsts orders in perturbation theory of SO(-2), Sp(2) or SU(2) Chern-Simons quantum holonomies and the partition function of the Q=4 Potts Model is built.

    了解养儿防老、母以子贵等传统生育文化的影响对中国稳定低生育水平至关重要。使用2008年中国老年人健康因素跟踪调查数据,通过logistic回归分析子女性别对老年父亲、母亲生活质量(包括生活满意度和婚姻满意度)、家庭地位(包括经济决策权和自我决策权)的影响发现,儿子的作用大大下降,儿女双全除了增加老年父亲的婚姻满意度以外,并没有提高老年人的生活质量,养儿未必能防老;生育儿子或儿女双全并没有提高老年母亲的家庭地位,甚至有儿子的老年母亲的经济决策权还更低;老年人自身的社会经济因素显著提高了老年人的生活质量和家庭地位。养儿防老、母以子贵等传统生育文化影响逐渐减弱,这对中国稳定低生育水平是一个利好的消息。%It is important to study the influences of traditional fertility culture (such as old - age sup- port and mother' s status depending on sons) on China's fertility. Using 2008 Chinese Longitudinal Healthy Longevity Survey, the paper analyzes the impact of sex of children on life quality of elderly par- ents (including life satisfaction and marital satisfaction) and family status (including economic decision - making power and self decision - making authority). Regression results show that son' s influence has decreased. Having both sons and daughters does not improve life quality of the elderly parents, but increases marital satisfaction of the elderly fathers. Bringing up sons not necessarily provides sup- port for ageing parents. Having sons or both sons and daughters may not help to improve family status of the elderly mothers, and the elderly mothers having sons only have even lower economic decision - making power. Social and economic situation of the elderly significantly improves their life quality and family status. Thus, influences of traditional fertility culture have been gradually weakening

    Full Text Available The relevance of cognitive assessment in Autism Spectrum Disorders is due to the association between cognitive deficits and severity of symptoms, adaptive functioning, prognosis and planning of more effective interventions.Thus, the aim of this study was to verify the non-verbal test of intelligence SON-R 2 ½ - 7 [a] adequacy in ASD group of children. The participants were 18 boys aged 4 and 7 years old, diagnosed based on the DSM-IV-TR and scored on screening instruments. The nonverbal intelligence test SON-R 2 ½ - 7 [a], the Autism Behavior Checklist (ABC, the Autism Screening Questionnaire (ASQ and the Vineland Adaptive Behavior Scales (VABS were used. The results showed that 55.6% of the group had IQs below average, and there was significant difference between the performance of TEA group and normative sample in the four subtests that compose the instrument. Intra-group analysis showed statistically significant differences between subtests, although these showed significant positive correlations with each other. Negative and significant correlations were observed between IQ Total in SON-R 2 ½ - 7 [a] the ABC and ASQ, as well as positive and significant correlations were observed between Total IQ and VABS. The results corroborate previous findings that indicate moderate relationships between intelligence, severityof symptoms and functionality, as well as the presence of specific profile of nonverbal performance in ASD group.

    Lee, Charlotte

    2011-01-01

    The relationship between father and son is a highly nuanced and persistent theme in Goethe's late novel Wilhelm Meisters Wanderjahre, but has received relatively little critical attention. Drawing on various aspects of the text, from the relationship between Wilhelm and his own son Felix, to the theme of migration from the ‘fatherland’, this essay contends that the relationship of the younger generation to the older traces a pattern of departure and return. The development in the son of an identity distinct and independent from that of the father is a preoccupation of the earlier chapters of the Wanderjahre in particular; but this process of individuation tends to be accompanied in the novel by continued, even increased, identification with the father, which may be conscious or unconscious. All the various stages of this fluctuating relationship are telescoped into a few rich, enigmatic images in the novel's closing scene, in which the threat of separation and the desire for proximity are held in suspension.

    Full Text Available From 1860 to 1960, Baltimore was an important center of the men’s ready-to- wear clothing industries. German-speaking Jews created many businesses that manufactured and sold underwear, men’s suits, and specialty items like hats and umbrellas. The straw hat making firm started by M.S. Levy is an interesting example of a Baltimore-based, family-owned niche business that existedfor 90 years, through three generations ofa singlefamily. The M.S. Levy and Sons story has two main chapters. The first covers the period from its founding by Michael Simon Levy in the 1870s through his son Julius’ death in 1926. This is the story of ascension. A premonition about the coming popularity of straw hats, together with a small but important technological breakthrough, positioned a family and a small industry for significant expansion. The second period began in 1930 with the introduction of wool felt hats and the death of William, M.S. Levy’s oldest son, and includes the Great Depression, unionization, merger, third generation leadership, and finally, in 1959, the family’s withdrawal from the industry. This later period, as told by grandsons of the founder, is the story of struggle followed by decline.

  2. Forest commons and local enforcement.

    2008-09-09

    This article examines the relationship between local enforcement and forests used as commons. It uses a unique multicountry dataset, created over the past 15 years by the International Forestry Resources and Institutions Research Program. Drawing on original enforcement and forest commons data from 9 countries, we find that higher levels of local enforcement have a strong and positive but complex relationship to the probability of forest regeneration. This relationship holds even when the influence of a number of other factors such as user group size, subsistence, and commercial importance of forests, size of forest, and collective action for forest improvement activities is taken into account. Although several of the above factors have a statistically significant relationship to changes in the condition of forest commons, differences in levels of local enforcement strongly moderate their link with forest commons outcomes. The research, using data from diverse political, social, and ecological contexts, shows both the importance of enforcement to forest commons and some of the limits of forest governance through commons arrangements.

    Full Text Available Abstract 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.

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.

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

    The introduction of Airborne Laser Scanning (ALS) to forests has been revolutionary during the last decade. This development was facilitated by combining earlier ranging lidar discoveries [1–5], with experience obtained from full-waveform ranging radar [6,7] to new airborne laser scanning systems which had components such as a GNSS receiver (Global Navigation Satellite System), IMU (Inertial Measurement Unit) and a scanning mechanism. Since the first commercial ALS in 1994, new ALS-based fore...

  9. Forest crimes as a threat to sustainable forest management

    Full Text Available From ancient times to the present day, forest public relations has been an issue on the agenda. This relationship’s purpose was initially needed for shelter and nutrition; however today this process has changed with urbanization, overpopulation and understanding the new functions of forests. When land ownership became a tool of production, offenses occurred in order to convert forestlands to agricultural lands. So the vast majority of the world’s forests have been lost for this reason. Today, deforestation is occurring in tropical countries that are expecting to gain agricultural area. The purpose of this study is to investigate the relationship between urbanization and the qualitative and quantitative characteristics of forest crimes, which are a major obstacle for sustainable forestry. Although forests cover about 27 % of Turkey’s territory, the forests are losing viability; the status of wood raw material per unit area and the total area of the country in the ratio of productive forests are becoming critical in Turkey. Turkey’s rugged terrain and factors such as human interventions, fires, deforestation for agriculture, illegal cuttings, or improper grazing reduce existing forests or cause deterioration of their structure. In the past, deforestation, as a result of human interventions in Turkey, was done by forest villagers who live in rural areas. The forest crimes depend on various socio-economic reasons and have many adverse effects on the sustainability of forest and forest existence. In developed countries, illegal interventions such as opening, grazing, cutting, occupation, use, settlement, or hunting crimes have been largely eliminated because of the absence of cadastral problems, the existence of more responsive people to protect the environment and forests and a rural population, which has a higher standard of living. In the last 20 years, there has been both a dramatic decrease in the population living in rural areas and a

  2. Large-scale fungal diversity assessment in the Andean Yungas forests reveals strong community turnover among forest types along an altitudinal gradient.

    Geml, József; Pastor, Nicolás; Fernandez, Lisandro; Pacheco, Silvia; Semenova, Tatiana A; Becerra, Alejandra G; Wicaksono, Christian Y; Nouhra, Eduardo R

    2014-05-01

    The Yungas, a system of tropical and subtropical montane forests on the eastern slopes of the Andes, are extremely diverse and severely threatened by anthropogenic pressure and climate change. Previous mycological works focused on macrofungi (e.g. agarics, polypores) and mycorrhizae in Alnus acuminata forests, while fungal diversity in other parts of the Yungas has remained mostly unexplored. We carried out Ion Torrent sequencing of ITS2 rDNA from soil samples taken at 24 sites along the entire latitudinal extent of the Yungas in Argentina. The sampled sites represent the three altitudinal forest types: the piedmont (400-700 m a.s.l.), montane (700-1500 m a.s.l.) and montane cloud (1500-3000 m a.s.l.) forests. The deep sequence data presented here (i.e. 4 108 126 quality-filtered sequences) indicate that fungal community composition correlates most strongly with elevation, with many fungi showing preference for a certain altitudinal forest type. For example, ectomycorrhizal and root endophytic fungi were most diverse in the montane cloud forests, particularly at sites dominated by Alnus acuminata, while the diversity values of various saprobic groups were highest at lower elevations. Despite the strong altitudinal community turnover, fungal diversity was comparable across the different zonal forest types. Besides elevation, soil pH, N, P, and organic matter contents correlated with fungal community structure as well, although most of these variables were co-correlated with elevation. Our data provide an unprecedented insight into the high diversity and spatial distribution of fungi in the Yungas forests. © 2014 John Wiley & Sons Ltd.

  3. Insights into dynamic mitotic chromatin organization through the NIMA kinase suppressor SonC, a chromatin-associated protein involved in the DNA damage response.

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

  4. On the likelihood of forests

    2016-08-01

    How complex a network is crucially impacts its function and performance. In many modern applications, the networks involved have a growth property and sparse structures, which pose challenges to physicists and applied mathematicians. In this paper, we introduce the forest likelihood as a plausible measure to gauge how difficult it is to construct a forest in a non-preferential attachment way. Based on the notions of admittable labeling and path construction, we propose algorithms for computing the forest likelihood of a given forest. Concrete examples as well as the distributions of forest likelihoods for all forests with some fixed numbers of nodes are presented. Moreover, we illustrate the ideas on real-life networks, including a benzenoid tree, a mathematical family tree, and a peer-to-peer network.

  5. Unbiased split variable selection for random survival forests using maximally selected rank statistics.

    Science.gov (United States)

    Wright, Marvin N; Dankowski, Theresa; Ziegler, Andreas

    2017-04-15

    The most popular approach for analyzing survival data is the Cox regression model. The Cox model may, however, be misspecified, and its proportionality assumption may not always be fulfilled. An alternative approach for survival prediction is random forests for survival outcomes. The standard split criterion for random survival forests is the log-rank test statistic, which favors splitting variables with many possible split points. Conditional inference forests avoid this split variable selection bias. However, linear rank statistics are utilized by default in conditional inference forests to select the optimal splitting variable, which cannot detect non-linear effects in the independent variables. An alternative is to use maximally selected rank statistics for the split point selection. As in conditional inference forests, splitting variables are compared on the p-value scale. However, instead of the conditional Monte-Carlo approach used in conditional inference forests, p-value approximations are employed. We describe several p-value approximations and the implementation of the proposed random forest approach. A simulation study demonstrates that unbiased split variable selection is possible. However, there is a trade-off between unbiased split variable selection and runtime. In benchmark studies of prediction performance on simulated and real datasets, the new method performs better than random survival forests if informative dichotomous variables are combined with uninformative variables with more categories and better than conditional inference forests if non-linear covariate effects are included. In a runtime comparison, the method proves to be computationally faster than both alternatives, if a simple p-value approximation is used. Copyright © 2017 John Wiley & Sons, Ltd.

  6. Shifts in functional traits elevate risk of fire-driven tree dieback in tropical savanna and forest biomes.

    Pellegrini, Adam F A; Franco, Augusto C; Hoffmann, William A

    2016-03-01

    Numerous predictions indicate rising CO2 will accelerate the expansion of forests into savannas. Although encroaching forests can sequester carbon over the short term, increased fires and drought-fire interactions could offset carbon gains, which may be amplified by the shift toward forest plant communities more susceptible to fire-driven dieback. We quantify how bark thickness determines the ability of individual tree species to tolerate fire and subsequently determine the fire sensitivity of ecosystem carbon across 180 plots in savannas and forests throughout the 2.2-million km(2) Cerrado region in Brazil. We find that not accounting for variation in bark thickness across tree species underestimated carbon losses in forests by ~50%, totaling 0.22 PgC across the Cerrado region. The lower bark thicknesses of plant species in forests decreased fire tolerance to such an extent that a third of carbon gains during forest encroachment may be at risk of dieback if burned. These results illustrate that consideration of trait-based differences in fire tolerance is critical for determining the climate-carbon-fire feedback in tropical savanna and forest biomes. © 2015 John Wiley & Sons Ltd.

    2011-09-20

    In the state’s Electricity Restructuring Act of 1998, the Commonwealth of Massachusetts recognized the opportunity and strategic benefits to diversifying its electric generation capacity with renewable energy. Through this legislation, the Commonwealth established one of the nation’s first Renewable Energy Portfolio Standard (RPS) programs, mandating the increasing use of renewable resources in its energy mix. Bioenergy, meeting low emissions and advanced technology standards, was recognized as an eligible renewable energy technology. Stimulated by the state’s RPS program, several project development groups have been looking seriously at building large woody biomass generation units in western Massachusetts to utilize the woody biomass resource. As a direct result of this development, numerous stakeholders have raised concerns and have prompted the state to take a leadership position in pursuing a science based analysis of biomass impacts on forest and carbon emissions, and proceed through a rulemaking process to establish prudent policy to support biomass development which can contribute to the state’s carbon reduction commitments and maintain safeguards for forest sustainability. The Massachusetts Sustainable Forest Bioenergy Initiative (SFBI) was funded by the Department of Energy and started by the Department of Energy Resources before these contentious biomass issues were fully raised in the state, and continued throughout the substantive periods of this policy development. Thereby, while SFBI maintained its focus on the initially proposed Scope of Work, some aspects of this scope were expanded or realigned to meet the needs for groundbreaking research and policy development being advanced by DOER. SFBI provided DOER and the Commonwealth with a foundation of state specific information on biomass technology and the biomass industry and markets, the most comprehensive biomass fuel supply assessment for the region, the economic development impact

  12. Persistent and pervasive compositional shifts of western boreal forest plots in Canada.

    Searle, Eric B; Chen, Han Y H

    2017-02-01

    Species compositional shifts have important consequences to biodiversity and ecosystem function and services to humanity. In boreal forests, compositional shifts from late-successional conifers to early-successional conifers and deciduous broadleaves have been postulated based on increased fire frequency associated with climate change truncating stand age-dependent succession. However, little is known about how climate change has affected forest composition in the background between successive catastrophic fires in boreal forests. Using 1797 permanent sample plots from western boreal forests of Canada measured from 1958 to 2013, we show that after accounting for stand age-dependent succession, the relative abundances of early-successional deciduous broadleaves and early-successional conifers have increased at the expense of late-successional conifers with climate change. These background compositional shifts are persistent temporally, consistent across all forest stand ages and pervasive spatially across the region. Rising atmospheric CO2 promoted early-successional conifers and deciduous broadleaves, and warming increased early-successional conifers at the expense of late-successional conifers, but compositional shifts were not associated with climate moisture index. Our results emphasize the importance of climate change on background compositional shifts in the boreal forest and suggest further compositional shifts as rising CO2 and warming will continue in the 21st century. © 2016 John Wiley & Sons Ltd.

    2013-09-01

    The persistent terrestrial carbon sink regulates long-term climate change, but its size, location, and mechanisms remain uncertain. One of the most promising terrestrial biogeochemical carbon sequestration mechanisms is the occlusion of carbon within phytoliths, the silicified features that deposit within plant tissues. Using phytolith content-biogenic silica content transfer function obtained from our investigation, in combination with published silica content and aboveground net primary productivity (ANPP) data of leaf litter and herb layer in China's forests, we estimated the production of phytolith-occluded carbon (PhytOC) in China's forests. The present annual phytolith carbon sink in China's forests is 1.7 ± 0.4 Tg CO2  yr(-1) , 30% of which is contributed by bamboo because the production flux of PhytOC through tree leaf litter for bamboo is 3-80 times higher than that of other forest types. As a result of national and international bamboo afforestation and reforestation, the potential of phytolith carbon sink for China's forests and world's bamboo can reach 6.8 ± 1.5 and 27.0 ± 6.1 Tg CO2  yr(-1) , respectively. Forest management practices such as bamboo afforestation and reforestation may significantly enhance the long-term terrestrial carbon sink and contribute to mitigation of global climate warming. © 2013 John Wiley & Sons Ltd.

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

  7. Forest liming increases forest floor carbon and nitrogen stocks in a mixed hardwood forest.

    2013-12-01

    In acid-impacted forests, decreased soil pH and calcium (Ca) availability have the potential to influence biotic and abiotic controls on carbon (C) and nitrogen (N) cycling. We investigated the effects of liming on above- and belowground C and N pools and fluxes 19 years after lime addition to the Woods Lake Watershed, Adirondack Park, New York, USA. Soil pH and exchangeable Ca remained elevated in the forest floor and upper mineral soil of limed areas. Forest floor C and N stocks were significantly larger in limed plots (68 vs. 31 Mg C/ha, and 3.0 vs. 1.5 Mg N/ha), resulting from a larger mass of Oa material. Liming reduced soil basal respiration rates by 17% and 43% in the Oe and Oa horizons, respectively. Net N mineralization was significantly lower in the limed soils for both forest floor horizons. Additional measurements of forest floor depth outside of our study plots, but within the treatment and control subcatchments also showed a deeper forest floor in limed areas; however, the mean depth of limed forest floor was 5 cm shallower than that observed in our study plots. Using a differential equation model of forest floor C dynamics, we found that liming effects on C fluxes measured within our study plots could explain the small observed increase in the Oe C stock but were not large enough to explain the increase in the Oa. Our catchment-wide assessment of forest floor depth, however, indicates that our plot analysis may be an overestimate of ecosystem-scale C and N stocks. Our results suggest that the mechanisms identified in our study, primarily liming-induced reduction in decomposition rates, may account for much of the observed increase in forest floor C. These findings emphasize the importance of understanding of the effects of liming in hardwood forests, and the long-term impacts of acid deposition on forest C and N uptake and retention.

    The forests of Southern United States are the source of many non-timber forest products (NTFPs). The collection, trade and use of these products have been important to rural economies since Europeans settled in this country. At the same time the plants from which these products originate are crucial to healthy ecosystems. Over the last decade, the market demand and the...

    Fractal geometry is a tool for describing and analyzing irregularity. Because most of what we measure in the forest is discontinuous, jagged, and fragmented, fractal geometry has potential for improving the precision of measurement and description. This study reviews the literature on fractal geometry and its applications to forest measurements.

    China is not rich in natural forest sources. Owing to natural and historical factors, forest fires have long been frequenting China. Forest fire prevention is the most important of all. Forest fire prevention and controlling have long been held as a very important factor in our ecological plans. Taking china 's special geographical location, topography, climate and the distribution of forest sources into consideration, we have every reason to believe that forest fires in China have their own special env...

    Full Text Available The forests of North America provide a variety of benefits including water, recreation, wildlife habitat, timber, and other forest products. However, they continue to face many biotic and abiotic stressors including fires, native and invasive pests, fragmentation, and air pollution. Forest health specialists have been monitoring the health of forests for many years. This paper highlights some of the most damaging forest stressors affecting North American forests in recent years and provides some projections of future risks.

  16. Methane Emissions from Upland Forests

    Global budgets ascribe 4-10% of atmospheric methane sinks to upland soils and assume that soils are the sole surface for methane exchange between upland forests and the atmosphere. The dogma that upland forests are uniformly atmospheric methane sinks was challenged a decade ago by the discovery of abiotic methane production from plant tissue. Subsequently a variety of relatively cryptic microbial and non-microbial methane sources have been proposed that have the potential to emit methane in upland forests. Despite the accumulating evidence of potential methane sources, there are few data demonstrating actual emissions of methane from a plant surface in an upland forest. We report direct observations of methane emissions from upland tree stems in two temperate forests. Stem methane emissions were observed from several tree species that dominate a forest located on the mid-Atlantic coast of North America (Maryland, USA). Stem emissions occurred throughout the growing season while soils adjacent to the trees simultaneously consumed methane. Scaling fluxes by stem surface area suggested the forest was a net methane source during a wet period in June, and that stem emissions offset 5% of the soil methane sink on an annual basis. High frequency measurements revealed diurnal cycles in stem methane emission rates, pointing to soils as the methane source and transpiration as the most likely pathway for gas transport. Similar observations were made in an upland forest in Beijing, China. However, in this case the evidence suggested the methane was not produced in soils, but in the heartwood by microbial or non-microbial processes. These data challenge the concept that forests are uniform sinks of methane, and suggest that upland forests are smaller methane sinks than previously estimated due to stem emissions. Tree emissions may be particularly important in upland tropical forests characterized by high rainfall and transpiration.

    Full Text Available Today, private forest owners (PFOs in Serbia cooperate in form of private forest owners associations (PFOAs. Currently, there are 20 PFOAs, of which 15 are in Timok region. Initiatives of PFOs from Timok forest area, animated the owners from other parts of the country and led to foundation of Serbian Federation of Forest Owners' Associations. Twelve of PFOAs from Timok forest area are the founders of Serbian private forest owners' umbrella organization. Restructuring of Public Enterprise (PE "Srbijasume", which started in 2001, led to development of private small and medium forest enterprises, engaged as contractors of PE for harvesting, timber transport and construction of forest roads. The objectives of this paper are to elaborate if there are differences between PFOs in Serbia and Timok region and to analyze organization of private forest owners in Timok forest area. In order to reach these objectives, results of PRIFORT project were used. This project focused on four countries of Western Balkans region: Bosnia and Herzegovina, Croatia, Serbia and Macedonia. The aim of this project was to explore precondition for formation of PFOs in this region. Quantitative survey (n = 350 of randomly selected PFOs was conducted in nine municipalities in Serbia, of which two were in Timok region (n = 100. The results show that there are differences between PFOs in Serbia and Timok region in number of PFOs, size of private property and in additional incentives. These results also indicate that economic interest is a motive for establishment of PFOAs and that state support is very important for their development. Since a number of PFOs are entrepreneurs, it can be assumed that, further development of theirs organizations could lead to development of SMEs clusters.

    @@ Forest disasters mainly refer to insect pest, rodent damage, forest fire and frost damage. Snow damage, windstorm, drought, flooding, landslide, mud-rock flow, environmental pollution and so on all cause damages to forest resources. The greatest damage is caused by forest disease,insect pests, rodents and fire. With the large-scale exploiture and serious denudation of primitive secondary forests, the appearance of artificial pure forests on a massive scale and the deterioration of the national forest eco-environment, forest damages caused by diseases, insect pests and rats have been on the increase, with the afflicted area doubling every ten years on the average for the period 1949~1989.
