Abstract:Of all feeding guilds, understorey insectivores are thought to be most sensitive to disturbance and forest conversion. We compared the composition of bird feeding guilds in tropical forest fragments with adjacent agro-ecosystems in a montane region of south-west Ethiopia. We used a series of point counts to survey birds in 19 agriculture and 19 forest sites and recorded tree species within each farm across an area of 40 × 35 km. Insectivores (~17 spp. per plot), frugivores (~3 spp. per plot) and omnivores (~5 spp. per plot) maintained species density across habitats, while granivores and nectarivores increased in the agricultural sites by factors of 7 and 3 respectively. Species accumulation curves of each guild were equal or steeper in agriculture, suggesting that agricultural and forest landscapes were equally heterogeneous for all bird guilds. Counter to most published studies, we found no decline in insectivore species richness with forest conversion. However, species composition differed between the two habitats, with certain forest specialists replaced by other species within each feeding guild. We suggest that the lack of difference in insectivorous species numbers between forest and agriculture in this region is due to the benign nature of the agricultural habitat, but also due to a regional species pool which contains many bird species which are adapted to open habitats.
Towards a New Sphere of Practices and Knowledge: The Militarization of Meteorology in Francoist Spain
Authors: Anduaga Aitor 
Published: February 2013

ArgumentThis paper analyzes the concept ofmilitarizationin both senses of the word, that of mobilization for war and that of social control exercised by military forces. During the Spanish Civil War (1936–1939), the role and nature of meteorology was transformed by the rebel band on the basis of the mythification of a Service model that was supported by victory and that would be projected as a paradigm for the postwar years. The newServicio Meteorológico Nacionalreflected the social control exerted by the Franco regime and its aeronautical and military interests. The “amphibianism” – or quality of being both civil and military simultaneously – is one of the main features of this transformation. Interestingly, this dual (civil and military) condition of meteorologist appears to be intrinsic to the construction of a new “sphere of practices and knowledge” in Francoist Spain.
Accommodating Climate Change Science: James Hansen and the Rhetorical/Political Emergence of Global Warming
Authors: Besel Richard D. 
Published: February 2013

ArgumentDr. James Hansen's 1988 testimony before the U.S. Senate was an important turning point in the history of global climate change. However, no studies have explained why Hansen's scientific communication in this deliberative setting was more successful than his testimonies of 1986 and 1987. This article turns to Hansen as an important case study in the rhetoric of accommodated science, illustrating how Hansen successfully accommodated his rhetoric to his non-scientist audience given his historical conditions and rhetorical constraints. This article (1) provides a richer explanation for the rhetorical/political emergence of global warming as an important public policy issue in the United States during the late 1980s and (2) contributes to scholarly understanding of the rhetoric of accommodated science in deliberative settings, an often overlooked area of science communication research.
Biobricks and Crocheted Coral: Dispatches from the Life Sciences in the Age of Fabrication
Authors: Roosth Sophia 
Published: February 2013

ArgumentWhat does “life” become at a moment when biological inquiry proceeds by manufacturing biological artifacts and systems? In this article, I juxtapose two radically different communities, synthetic biologists and Hyperbolic Crochet Coral Reef crafters (HCCR). Synthetic biology is a decade-old research initiative that seeks to merge biology with engineering and experimental research with manufacture. The HCCR is a distributed venture of three thousand craftspeople who cooperatively fabricate a series of yarn and plastic coral reefs to draw attention to the menace climate change poses to the Great Barrier and other reefs. Interpreting these two groups alongside one another, I suggest that for both, manufacturing biological artifacts advances their understandings of biology: in a rhetorical loop, they build new biological things in order to understand the things they are making. The resulting fabrications condense scientific and folk theories about “life” and also undo “life” as a coherent analytic object.

Published: February 2013

SUMMARYWithin China's Poyang Lake region, close interactions between wild migratory birds and domestic poultry are common and provide an opportunity for the transmission and subsequent outbreaks of highly pathogenic avian influenza (HPAI) virus. We overlaid a series of ecological factors associated with HPAI to map the risk of HPAI in relation to natural and anthropogenic variables, and we identified two hotspots for potential HPAI outbreaks in the Poyang Lake region as well as three corridors connecting the two hotspot areas. In hotspot I, there is potential for migratory birds to bring new avian influenza (AI) strains that can reassort with existing strains to form new AI viruses. Hotspot II features high-density poultry production where outbreaks of endemic AI viruses are likely. The three communication corridors that link the two hotspots further promote HPAI H5N1 transmission and outbreaks and lead to the persistence of AI viruses in the Poyang Lake region. We speculate that the region's unevenly distributed poultry supply-and-demand system might be a key factor inducing HPAI H5N1 transmission and outbreaks in the Poyang Lake region.
Gene–environment correlation in developmental psychopathology
Authors: Knafo Ariel , Jaffee Sara R. 
Published: February 2013

AbstractModern research acknowledges that psychopathology and individual differences in normal development are the joint products of both biological and social influences. Although there have been numerous publications on Gene × Environment interactions in the past decade, gene–environment correlation is another important form of gene–environment interplay that has received less attention. This Special Section demonstrates, using a range of methodological approaches, the importance of gene–environment correlation in developmental psychopathology. Several types of gene–environment correlation are described, including passive, evocative, and active. Other studies highlight the potential for gene–environment correlation to obscure associations between risk exposures and child psychopathology. Future directions for gene–environment correlation research are discussed.
Examining the role of passive gene–environment correlation in childhood depression using a novel genetically sensitive design

Published: February 2013

AbstractParental depression is associated with disruptions in the parent–child relationship, exposure to stressful family life events, and offspring depressive symptoms. Evidence suggests that intergenerational transmission of depression involves environmental and inherited contributions. We sought to evaluate the role of passive gene–environment correlation (rGE) in relation to depression, family life events that were due to parental behavior, and parental positivity in a sample where children varied in genetic relatedness to their rearing parents. Our study included 865 families with children born through assisted conception (444 related to both parents, 210 related to the mother only, 175 related to the father only, and 36 related to neither parent). Consistent with previous studies, the intergenerational transmission of depressive symptoms was largely due to environmental factors, although parent and child gender influenced results. Maternal and paternal depressive symptoms were associated with reduced positivity and increased parentally imposed life events regardless of parent–child relatedness. Results of path analysis were consistent with passive rGE for both maternal and paternal positivity in that positivity partially mediated the link between maternal/paternal depression and child depression only in genetically related parent–child pairs. Results also suggested passive rGE involving parentally imposed life events for mothers and fathers although passive rGE effects were smaller than for positivity.
Childhood temperament: Passive gene–environment correlation, gene–environment interaction, and the hidden importance of the family environment

AbstractBiological parents pass on genotypes to their children, as well as provide home environments that correlate with their genotypes; thus, the association between the home environment and children's temperament can be genetically (i.e., passive gene–environment correlation) or environmentally mediated. Furthermore, family environments may suppress or facilitate the heritability of children's temperament (i.e., gene–environment interaction). The sample comprised 807 twin pairs (mean age = 7.93 years) from the longitudinal Wisconsin Twin Project. Important passive gene–environment correlations emerged, such that home environments were less chaotic for children with high effortful control, and this association was genetically mediated. Children with high extraversion/surgency experienced more chaotic home environments, and this correlation was also genetically mediated. In addition, heritability of children's temperament was moderated by home environments, such that effortful control and extraversion/surgency were more heritable in chaotic homes, and negative affectivity was more heritable under crowded or unsafe home conditions. Modeling multiple types of gene–environment interplay uncovered the complex role of genetic factors and the hidden importance of the family environment for children's temperament and development more generally.

Published: February 2013

AbstractDepression is known to be associated with a wide array of environmental factors. Such associations are due at least in part to genetic influences on both. This issue has been little explored with preadolescent children. Measures of family chaos and parenting style at age 9 and child depressive symptoms at age 12 were completed by 3,258 twin pairs from the Twins Early Development Study and their parents. Quantitative genetic modeling was used to explore common and unique genetic and environmental influences on both family environment and later depressive symptoms. Depressive symptoms at age 12 were significantly heritable. Moderate genetic effects influenced parenting style and family chaos at the age of 9, indicating gene–environment correlation. There were significant genetic correlations between family environment and depressive symptoms. There was some evidence of a Gene × Environment interaction, with stronger genetic effects on depressive symptoms for children with more suboptimal family environment. There was an Environment × Environment interaction, with effects of nonshared environment on depressive symptoms stronger for twins with more adverse parenting experiences. There is some evidence for gene–environment correlation between aspects of family environment in middle childhood and subsequent depressive symptoms. This suggests that one of the mechanisms by which genes lead to depressive symptoms may be by themselves influencing depressogenic environments.

AbstractSelf-control, involving processes such as delaying gratification, concentrating, planning, following instructions, and adapting emotions and behavior to situational requirements and social norms, may have a profound impact on children's adjustment. The importance of self-control suggests that parents are likely to modify their parenting based on children's ability for self-control. We study the effect of children's self-control, a trait partially molded by genetics, on their mothers' parenting, a process of evocative gene–environment correlation. Israeli 3.5-year-old twins (N = 320) participated in a lab session in which their mothers' parenting was observed. DNA was available from most children (N = 228). Mothers described children's self-control in a questionnaire. Boys were lower in self-control and received less positive parenting from their mothers, in comparison with girls. For boys, and not for girls, the serotonin transporter linked polymorphic region gene predicted mothers' levels of positive parenting, an effect mediated by boys' self-control. The implications of this evocative gene–environment correlation and the observed sex differences are discussed.

AbstractGene–environment correlations (rGE) have been demonstrated in behavioral genetic studies, but rGE have proven elusive in molecular genetic research. Significant gene–environment correlations may be difficult to detect because potential moderators could reduce correlations between measured genetic variants and the environment. Molecular genetic studies investigating moderated rGE are lacking. This study examined associations between child catechol-O-methyltransferase genotype and aspects of positive parenting (responsiveness and warmth), and whether these associations were moderated by parental personality traits (neuroticism and extraversion) among a general community sample of third, sixth, and ninth graders (N = 263) and their parents. Results showed that parent personality traits moderated the rGE association between youths' genotype and coded observations of positive parenting. Parents with low levels of neuroticism and high levels of extraversion exhibited greater sensitive responsiveness and warmth, respectively, to youth with the valine/valine genotype. Moreover, youth with this genotype exhibited lower levels of observed anger. There was no association between the catechol-O-methyltransferase genotype and parenting behaviors for parents high on neuroticism and low on extraversion. Findings highlight the importance of considering moderating variables that may influence child genetic effects on the rearing environment. Implications for developmental models of maladaptive and adaptive child outcomes, and interventions for psychopathology, are discussed within a developmental psychopathology framework.
Changes in marital conflict and youths' responses across childhood and adolescence: A test of sensitization
Authors: Goeke-Morey Marcie C. , Papp Lauren M. , Cummings E. Mark 
Published: February 2013

AbstractAlthough the sensitization hypothesis is fundamental to process-oriented explanations of the effects of marital conflict on children, few longitudinal tests of the theory's propositions have been conducted. Hierarchical linear modeling was used in this prospective, longitudinal study (n = 297 families) to assess changes in the dimensions of responding to conflict (i.e., emotional, cognitive, and behavioral) for 3 consecutive years in youths between the ages of 8 and 19 years. Moreover, to test the notion of sensitization, analyses were conducted to examine whether change in marital conflict predicted change in children's responding across middle childhood and adolescence. Supporting the sensitization hypothesis, increases in exposure to hostile marital conflict were associated with increases in children's negative emotionality, threat, self-blame, and skepticism about resolution. With a few exceptions, the effects were largely consistent for boys and girls and for younger and older children.

AbstractTo better understand mechanisms underlying the intergenerational transmission of social anxiety, we used a prospective adoption design to examine the roles of genetic influences (inferred from birth mothers' social phobia) and rearing environment (adoptive mothers' and fathers' responsiveness) on the development of socially inhibited, anxious behaviors in children between 18 and 27 months of age. The sample consisted of 275 adoption-linked families, each including an adopted child, adoptive parents, and a birth mother. Results indicated that children whose birth mothers met criteria for the diagnosis of social phobia showed elevated levels of observed behavioral inhibition in a social situation at 27 months of age if their adoptive mothers provided less emotionally and verbally responsive rearing environments at 18 months of age. Conversely, in the context of higher levels of maternal responsiveness, children of birth mothers with a history of social phobia did not show elevated levels of behavioral inhibition. These findings on maternal responsiveness were replicated in a model predicting parent reports of child social anxiety. The findings are discussed in terms of gene–environment interactions in the intergenerational transmission of social anxiety.
Coping with highly imbalanced datasets: A case study with definition extraction in a multilingual setting
Authors: DEL GAUDIO ROSA , BATISTA GUSTAVO , BRANCO ANTÓNIO 
Published: February 2013

AbstractThis paper addresses the task of automatic extraction of definitions by thoroughly exploring an approach that solely relies on machine learning techniques, and by focusing on the issue of the imbalance of relevant datasets. We obtained a breakthrough in terms of the automatic extraction of definitions, by extensively and systematically experimenting with different sampling techniques and their combination, as well as a range of different types of classifiers. Performance consistently scored in the range of 0.95–0.99 of area under the receiver operating characteristics, with a notorious improvement between 17 and 22 percentage points regarding the baseline of 0.73–0.77, for datasets with different rates of imbalance. Thus, the present paper also represents a contribution to the seminal work in natural language processing that points toward the importance of exploring the research path of applying sampling techniques to mitigate the bias induced by highly imbalanced datasets, and thus greatly improving the performance of a large range of tools that rely on them.

Published: February 2013

AbstractThis study examined whether processing of emotional words impairs cognitive performance in acutely ill patients with pediatric bipolar disorder (PBD), with or without comorbid attention-deficit hyperactivity disorder (ADHD), relative to healthy controls (HC). Forty youths with PBD without ADHD, 20 youths with PBD and ADHD, and 29 HC (mean age = 12.97 ± 3.13) performed a Synonym Matching task, where they decided which of two probe words was the synonym of a target word. The three words presented on each trial all had the same emotional valence, which could be negative, positive, or neutral. Relative to HC both PBD groups exhibited worse accuracy for emotional words relative to neutral ones. This effect was greater with negative words and observed regardless of whether PBD patients had comorbid ADHD. In the PBD group without ADHD, manic symptoms correlated negatively with accuracy for negative words, and positively with reaction time (RT) for all word types. Our findings suggest a greater disruptive effect of emotional valence in both PBD groups relative to HC, reflecting the adverse effect of altered emotion processing on cognitive function in PBD. Future studies including an ADHD group will help clarify how ADHD symptoms may affect emotional interference independently of PBD. (JINS, 2013, 19, 1–12)

Published: February 2013

AbstractObjectiveThe present study aimed to estimate the health benefits of selective taxation of healthy and unhealthy food commodities in relation to CVD and nutrition-related cancers.DesignThe potential health effects of a selective taxation scenario were estimated as changes in the burden of disease, measured by disability-adjusted life years, from health outcomes affected by the changes in food intake. The change in burden of a disease was calculated as the change in incidence of the disease due to a modified exposure level, using the potential impact fraction. Estimates of relative risk for the associations between various foods and relevant diseases were found through a literature search and used in the calculation of potential impact fractions.SettingThe study was based in Denmark, estimating the health effects of a Danish selective taxation scenario.SubjectsThe potential health effects of selective taxation were modelled for the adult Danish population.ResultsHalving the rate of value-added tax on fruit and vegetables and increasing the tax on fats would result in moderate reductions in the burden of disease from IHD, ischaemic stroke, and colorectal, lung and breast cancer (0·4–2·4 % change). The largest effect could be obtained through increased intake of fruit and vegetables (0·9–2·4 %).ConclusionsApplying selective taxation to healthy and unhealthy foods can moderately reduce the burden of disease in the Danish population.
