The importance of dispersal for the maintenance of biodiversity, while long-recognized, has remained unresolved. We used molecular markers to measure effective dispersal in a natural population of the vertebrate-dispersed Neotropical tree, Simarouba amara (Simaroubaceae) by comparing the distances between maternal parents and their offspring and comparing gene movement via seed and pollen in the 50 ha plot of the Barro Colorado Island forest, Central Panama. In all cases (parent-pair, mother-offspring, father-offspring, sib-sib) distances between related pairs were significantly greater than distances to nearest possible neighbours within each category. Long-distance seedling establishment was frequent: 74% of assigned seedlings established > 100 m from the maternal parent [mean = 392 +/- 234.6 m (SD), range = 9.3-1000.5 m] and pollen-mediated gene flow was comparable to that of seed [mean = 345.0 +/- 157.7 m (SD), range 57.6-739.7 m]. For S. amara we found approximately a 10-fold difference between distances estimated by inverse modelling and mean seedling recruitment distances (39 m vs. 392 m). Our findings have important implications for future studies in forest demography and regeneration, with most seedlings establishing at distances far exceeding those demonstrated by negative density-dependent effects.

Social factors, including poverty, are known risk factors for depression. In a previous study conducted in Khayelitsha, a very poor peri-urban settlement near Cape Town, a 34.7% prevalence rate for postpartum depression was found, roughly three times the expected rate internationally. This article is a report on a logistical regression analysis, showing that the odds ratios for the probability of maternal depression at two months were: for the infant being unwanted, OR=4.33, 95% CI: (1.75; 11.60); for the father's negative attitude towards the infant, OR=6.03, 95% CI: (2.01; 20.09); and for the mother cohabiting with (as opposed to not living with) a male partner, OR=2.77, 95% CI: (1.08; 7.69). The odds ratios for the probability of the mother being insensitive towards the infant at two months were: for the mother aged 20 to 24 years, OR=0.40, 95% CI: (0.10; 1.42); for the mother aged 25 to 29 years, OR=0.24, 95% CI: (0.06; 0.77); for the mother aged 30 years or older, OR=0.27, 95% CI: (0.07; 0.90); and for the mother receiving no help from her partner, OR=2.12, 95% CI: (1.05; 4.33). Since data were collected cross-sectionally, it is not possible to draw conclusions about causal pathways. The findings support further investigation into the precursors of, and risk factors for, postpartum depression amongst poor South African women.

Background: Children’s representations of mothers in doll-play are associated with child adjustment. Despite the importance of fathers for children’s adjustment, especially in the context of maternal psychopathology, few studies have considered children’s representations of their fathers. Method: We examined the portrayal of fathers by 5-year-old children of depressed (N = 55) and non-depressed (N = 39) mothers in a doll-play procedure concerning family experience. Results: Children gave equal prominence in their play to mothers and fathers. Representations of fathers were unrelated to maternal mood, but were associated with parental conflict. Representations of child care for the father that was unreciprocated predicted poor child adjustment in school, but only in children exposed to maternal postnatal depression. Conclusions: It may be clinically useful to consider children’s distinctive representations of their mother and father; but the concept of parentification in relation to risk and resilience effects requires refinement.

The essay asserts that, since pioneering work in the 1970s and 80s (in Screen in particular), the study of classical Hollywood cinema has failed adequately to acknowledge and understand the role of spectacle therein. This essay outlines theoretical but, even more, practical understandings of particular kinds of spectacle; they are susceptible to the practice of close analysis. Seeking to discuss spectacle in precise terms and in particular contexts, I define two kinds of spectacle associated with the historical film: ‘the decor of history’ and ‘the spectacular vista’. The example of Gone with the Wind illustrates the interrelationship between these two kinds of spectacle and their associations with particular ideas of femininity and masculinity. This gendering of spectacle is related to ‘the historical gaze’, a performative gesture that exemplifies the wider rhetoric of historical films, in their seeking to address the historical knowledge of the film spectator and to uphold a vision of history as being driven by powerful men, aware of their own destiny. Over the course of the three famous hilltop scenes in Gone with the Wind, one can plot Scarlett O'Hara's increased access to this kind of foresight and fortitude coded as ‘masculine’. This character arc can also be traced through Scarlett's shifting place within the film's use of spectacle: she begins the film wholly preoccupied with the domestic world of lavish parties and beautiful gowns; however, after her encounter with cataclysmic history visualized as a vast, terrible spectacle (the fall of Atlanta), Scarlett assumes the role occupied by her broken and emasculated father.

This study describes the validation of short tandem repeat (STR) systems for the resolution of cases of disputed parentage where only a single parent is available for testing or where the claimed relationship of both parents is in doubt and also cases where sibship must be tested. Three separate multiplex systems the Second Generation Multiplex, Powerplex 1.2 and FFFL have been employed, giving a total of 16 STR loci. Both empirical and theoretical approaches to the validation have been adopted. Appropriate equations have been derived to calculate likelihood ratios for different relationships, incorporating a correction for subpopulation effects. An F(ST) point estimate of 1% has been applied throughout. Empirically, 101 cases of alleged father, alleged mother and child where analysed using six SLP systems and also using the three multiplex STR systems. Of the 202 relationships tested, 197 were independently resolved by both systems, providing either clear evidence of non-parentage or strong support for the relationship.

Unique residential history data with retrospective information on parental assets are used to study household wealth mobility in 141 villages in rural Bangladesh. Regression estimates of father–son correlations and analyses of intergenerational transition matrices show substantial persistence in wealth even when we correct for measurement errors in parental wealth. We do not find wealth mobility to be higher between periods of a person's life than between generations. We find that the process of household division plays an important role: sons who splinter off from the father's household experience greater (albeit downward) mobility in wealth. Despite significant occupational mobility across generations, its contribution to wealth mobility, net of human capital attainment of individuals, appears insignificant. Low wealth mobility in our data is primarily explained by intergenerational persistence in educational attainment.

The article looks at three antifascist films from the 1980s by the East German film company DEFA: Jürgen Brauer's Pugowitza (1981), Egon Schlegel's Die Schüsse der Arche Noah (1983), and Helmut Dziuba's Jan auf der Zille (1986), which during this final decade of the East German state re-examine an ideologically seminal constellation of the GDR's official antifascism – the relationship between antifascist father and son. Linking generational and political succession, the father-son relationship helped to legitimise the GDR as a state in which the young continued the antifascist fight of the old communists against the Nazi dictatorship. From the 1950s on, DEFA films contributed to the visualisation of this relationship, codifying it not only as heroic but also as ‘natural’: the assumed innocence of the communist son was meant to naturalise the father's antifascist/communist cause. The 1980s saw this naturalised political succession questioned. By re-telling the canonised father-son story, the three films visualise the generational antifascist contract as flawed. Re-deploying the son's assumed innocence in a critique of the father, they explore new endings to the antifascist story and revive the discussion of categories like ‘victim’ and ‘perpetrator’.// Der Aufsatz untersucht drei antifaschistische Filme der ostdeutschen Filmgesellschaft DEFA aus den 1980er Jahren: Jürgen Brauers Pugowitza (1981), Egon Schlegels Die Schüsse der Arche Noah (1983) und Helmut Dziubas Jan auf der Zille (1986). Alle drei Filme wurden im letzten Jahrzehnt der DDR gedreht und greifen eine ideologisch tragende Konstellation des offiziellen DDR-Antifaschismus auf – die Beziehung zwischen antifaschistischem Vater und Sohn. In der Vater-Sohn-Beziehung verband sich Generationenabfolge mit politischer Nachkommenschaft, eine Verbindung, die half, die DDR als einen Staat zu legitimieren, in dem die Jungen den antifaschistischen Kampf der alten Kommunisten gegen die Nazi-Diktatur weiterführten. Seit den 1950er Jahren beteiligte sich die DEFA an der Visuali-sierung dieser Beziehung und kodifizierte sie nicht nur als heldenhaft, sondern auch als ‘natürlich’: die behauptete Unschuld der kommunistschen Söhne diente dazu, den antifaschistisch-kommunistischen Kampf der Väter zu naturalisieren. Die solcher Art politisch interpretierte Generationenabfolge verlor ihre Natürlichkeit, als sie in den 1980er Jahren kritisch befragt wurde. Im nochmaligen Erzählen der kanonisierten Vater-Sohn-Geschichte wird die Brüchigkeit des antifaschistischen Gesellschaftsvertrags in allen drei Filmen sichtbar. Die vermeintliche Unschuld der Söhne wird nun zu einer Kritik der Väter genutzt, wobei die Filme ein neues Ende für die antifaschistische Geschichte erkunden und die Debatte über Kategorien wie ‘Opfer’ und ‘Täter’ wieder aufnehmen.

Cognitive theories emphasise the role of dysfunctional beliefs about sleep in the development and maintenance of sleep-related problems (SRPs). The present research examines how parents' dysfunctional beliefs about children's sleep and child dysfunctional beliefs about sleep are related to each other and to children's subjective and objective sleep. Participants were 45 children aged 11 -12 years and their parents. Self-report measures of dysfunctional beliefs about sleep and child sleep were completed by children, mothers and fathers. Objective measures of child sleep were taken using actigraphy. The results showed that child dysfunctional beliefs about sleep were correlated with father (r=.43, p<.05) and mother (r=.43, p<.05) reported child SRPs, and with Sleep Onset Latency (r=.34, p<.05). Maternal dysfunctional beliefs about child sleep were related to child SRPs as reported by mothers (r=.44, p<.05), and to child dysfunctional beliefs about sleep (r=.37, p<.05). Some initial evidence was found for a mediation pathway in which child dyfunctional beliefs mediate the relationship between parent dysfunctional beliefs and child sleep. The results support the cognitive model of SRPs and contribute to the literature by providing the first evidence of familial aggregation of dysfunctional beliefs about sleep.

During his lifetime, Sir Bernard Spilsbury was referred to as the ‘‘father of forensic medicine.’’ He became a household name as a result of several famous cases. Several articles have been written about his life and work, but an objective assessment has proved difficult because of the lack of available material that Spilsbury himself produced. His main legacy has been a series of case cards, but for many years these were unavailable to the researcher. In 2008, a collection of some 4000 of Spilsbury’s case cards was bought by The Wellcome Library in London and therefore entered the public domain. In this article, we report our study of 650 of these cards. We discuss trends in Spilsbury’s work and several specific cases in more detail. These cards allow an objective view to be taken of Spilsbury’s everyday work, and we feel that some reappraisal of his legacy is now timely

Parents have large genetic and environmental influences on offspring’s cognition, behavior, and brain. These intergenerational effects are observed in mood disorders, with particularly robust association in depression between mothers and daughters. No studies have thus far examined the neural bases of these intergenerational effects in humans. Corticolimbic circuitry is known to be highly relevant in a wide range of processes including mood regulation and depression. These findings suggest that corticolimbic circuitry may also show matrilineal transmission patterns. We therefore examined human parent-offspring association in this neurocircuitry, and investigated the degree of association in gray matter volume between parent and offspring. We used voxel-wise correlation analysis in a total of 35 healthy families, consisting of parents and their biological offspring. We found positive associations of regional grey matter volume in the corticolimbic circuit including the amygdala, hippocampus, anterior cingulate cortex, and ventromedial prefrontal cortex between biological mothers and daughters. This association was significantly greater than mother-son, father-daughter, and father-son associations. The current study suggests that the corticolimbic circuitry, which has been implicated in mood regulation, shows a matrilineal specific transmission patterns. Our preliminary findings are consistent with what has been found behaviorally in depression, and may have clinical implications for disorders known to have dysfunction in mood regulation such as depression. Studies such as ours will likely bridge animal work examining gene expression in the brains and clinical symptom-based observations, and provide promising ways to investigate intergenerational transmission patterns in the human brain.

Female aggregation and male territoriality are considered to be hallmarks of polygynous mating systems. The development of genetic parentage assignment has called into question the accuracy of behavioral traits in predicting true mating systems. In this study we use 14 microsatellite markers to explore the mating system of one of the most behaviorally polygynous species, the California sea lion (Zalophus californianus). We sampled a total of 158 female-pup pairs and 99 territorial males across two breeding rookeries (San Jorge and Los Islotes) in the Gulf of California, Mexico. Fathers could be identified for 30% of pups sampled at San Jorge across three breeding seasons and 15% of sampled pups at Los Islotes across two breeding seasons. Analysis of paternal relatedness between the pups for which no fathers were identified (sampled over four breeding seasons at San Jorge and two at Los Islotes) revealed that few pups were likely to share a father. Thirty-one percent of the sampled males on San Jorge and 15% of the sampled males on Los Islotes were assigned at least one paternity. With one exception, no male was identified as the father of more than two pups. Furthermore, at Los Islotes rookery there were significantly fewer pups assigned paternity than expected given the pool of sampled males (p<0.0001). Overall, we found considerably lower variation in male reproductive success than expected in a species that exhibits behavior associated with strongly polygynous mating. Low variation in male reproductive success may result from heightened mobility among receptive females in the Gulf of California, which reduces the ability of males to monopolize groups of females. Our results raise important questions regarding the adaptive role of territoriality and the potential for alternative mating tactics in this species.

We identified a 4-year-old Brazilian boy from a family of Japanese descent and history of consanguinity, who suffered from severe recurrent pneumonia. He carries factor H (FH) deficiency associated with reduced levels of component C9 and low serum levels of C3 and factor B. His mother also presented low levels of these proteins and factor I, while his father and sister had only lower levels of FH. Western blot assays confirmed the complete absence of FH and FHL-1 polypeptides in this patient. Sequencing of the proband`s FH cDNA revealed a homozygous G453A substitution, encoding an Arg(127)His change. His mother, father and sister are heterozygous for this substitution. Despite the absence of FH in the plasma, this protein was detected in the patient`s fibroblasts, suggesting that Arg(127) may be important for FH secretion. Low concentrations of C9 were detected in the proband serum but no mutations in the patient`s C9 gene or promoter have been identified, suggesting that this is a consequence of uncontrolled complement activation and high C9 consumption.

The history of rhetorics in documentary film is a long one. The French brothers Louise and Auguste Lumiére were among the first persons who produced a documentary and their work has had a big impression in the history of documentary during the 1900 century. John Grierson has been called “the father” of documentary film. He produced films in the English speaking part of the world and he is the founder of the concept “documentary film”. Propaganda filming has a big part in the history of documentary film. Most frequently it appeard in Germany before and during the secound WW II, but propaganda films has been produced in Great Britain and USA as well as in other parts of the world. Rhetorics are of current interest today. It effects the news, papers, magazines, books and movies. The purpose with this essay is to investigate the rhetorics in Michael Moores controversial documentary of September 11th, Fahrenheit 9/11. The main question is: what rhetorical tools does Michael Moore use in order to communicate his politcal message in Fahrenheit 9/11? The rhetorical analysis includes exordium, narratio, propsitio, argumentatio and conclusio as well as ethos, logos and pathos. In order to conduct the analysis I have used Kurt Johannesson’s book Retorik eller konsten att övertyga, Maria Karlberg and Brigitte Mral’s book Heder och påverkan. Att analysera modern retorik. And at last a chapter by Brigitte Mral named Retorikanalys in the book Metoder i kommunikationeverenskap, by Mats Ekström and Larsåke Larsson. For the background about the history of documentary film I have used Barsam M. Richard, Nonfiction Film A Critical History and Bjørn Sørenssen’s book Å fange virkeligheten –Dokumentarfilmens århundre.The analysis shows that Moore uses different rhetorical tools in order to point out that George W Bush is the wrong man for the role as the president of United States of America. Some of the most effective tools that Moores uses are his own voice, pictures who awakes emotions, recordings and sharp arguments. His way of using ethos, logos and pathos is very clear. The disposal can also be distinct discern, however there are some exceptions towards the classical rhetoric. One example is that Moore doesn´t describe the arrangement of the movie in exordium.

In the home of others: exploring new sites and methods when investigating the doings of gender, class and ethnicity What role does the experience of being in and observing other people’s home play informing one’s gender and class identities and family aspirations? And how can it be explored? Through the traditions of socialization theory the everyday/-night experiences of family life are objectified into an institution (the family) with abstracted relations (mother-father-child) and functions (”primary socialization”). This is a view directly related to ruling relations through which the family is institutionalized, by rules and regulations, and made accountable as such. Hereby the question of experiences of other sites (and localities!) and other relations when forming one’s gender and family aspirations are not raised. In this article it is argued that when using an alternative approach (the method of inquiry proposed by Dorothy E. Smith) and alternative methods (memory work) the door to other homes is opened. Using experience stories a picture is drawn where new sites and relations are made visible as crucial contexts where gender and family life is explored and learned. By illuminating the ”work knowledge” of family life another way of mapping is presented, a way that extends and transforms the traditions within family research.

The aim of the project is to examine the music salon in Falun as a part of the mining community and in the historical context of European salon culture. A specifc goal is to develop a deeper understanding about the salon when it comes to education and pedagogic ideas. Of a certain interest is Johan Henrik Munktell’s (1804-1861) education travelling (bildningsresor). Inspired by Mendelssohn’s music salon in Berlin and the early salons in Upp-sala he created his own salon in Grycksbo. A letter collection from J.H. Munktell to his father J.J. Munktell in 1828-30 can be considered a unique historical material, which places the salon in Falun in a continental context of culture, education and industrial pretensions. The results have potential to extend the knowledge of Nordic salon culture and how it has infuenced general pedagogy and music education.
