Other better versus self better in baboons: an evolutionary approach of social comparison

Comparing oneself with others is an important characteristic of human social life, but the link between human and non-human forms of social comparison remains largely unknown. The present study used a computerized task presented in a social context to explore psychological mechanisms supporting social comparison in baboons and compare major findings with those usually observed in humans. We found that the effects of social comparison on subject's performance were guided both by similarity (same versus different sex) and by task complexity. Comparing oneself with a better-off other (upward comparison) increased performance when the other was similar rather than dissimilar, and a reverse effect was obtained when the self was better (downward comparison). Furthermore, when the other was similar, upward comparison led to a better performance than downward comparison. Interestingly, the beneficial effect of upward comparison on baboons' performance was only observed during simple task. Our results support the hypothesis of shared social comparison mechanisms in human and non-human primates.
Whole-Gene Positive Selection, Elevated Synonymous Substitution Rates, Duplication, and Indel Evolution of the Chloroplast clpP1 Gene

Background Synonymous DNA substitution rates in the plant chloroplast genome are generally relatively slow and lineage dependent. Non-synonymous rates are usually even slower due to purifying selection acting on the genes. Positive selection is expected to speed up non-synonymous substitution rates, whereas synonymous rates are expected to be unaffected. Until recently, positive selection has seldom been observed in chloroplast genes, and large-scale structural rearrangements leading to gene duplications are hitherto supposed to be rare. Methodology/Principle Findings We found high substitution rates in the exons of the plastid clpP1 gene in Oenothera (the Evening Primrose family) and three separate lineages in the tribe Sileneae (Caryophyllaceae, the Carnation family). Introns have been lost in some of the lineages, but where present, the intron sequences have substitution rates similar to those found in other introns of their genomes. The elevated substitution rates of clpP1 are associated with statistically significant whole-gene positive selection in three branches of the phylogeny. In two of the lineages we found multiple copies of the gene. Neighboring genes present in the duplicated fragments do not show signs of elevated substitution rates or positive selection. Although non-synonymous substitutions account for most of the increase in substitution rates, synonymous rates are also markedly elevated in some lineages. Whereas plant clpP1 genes experiencing negative (purifying) selection are characterized by having very conserved lengths, genes under positive selection often have large insertions of more or less repetitive amino acid sequence motifs. Conclusions/Significance We found positive selection of the clpP1 gene in various plant lineages to correlated with repeated duplication of the clpP1 gene and surrounding regions, repetitive amino acid sequences, and increase in synonymous substitution rates. The present study sheds light on the controversial issue of whether negative or positive selection is to be expected after gene duplications by providing evidence for the latter alternative. The observed increase in synonymous substitution rates in some of the lineages indicates that the detection of positive selection may be obscured under such circumstances. Future studies are required to explore the functional significance of the large inserted repeated amino acid motifs, as well as the possibility that synonymous substitution rates may be affected by positive selection.
Occurrence of the Carbapenem-Hydrolyzing β-Lactamase Gene blaOXA-48 in the Environment in Morocco

The bla OXA-48 gene is plasmid borne and encodes a carbapenem-hydrolyzing class D β-lactamase that was first identified in a Klebsiella pneumoniae clinical isolate in Turkey in 2004 ([11][1]). The high prevalence of OXA-48 producers in Turkey is well established ([3][2]), but there are also
Gender Differences in the Human Cerebral Cortex: More Neurons in Males; More Processes in Females

This study's objective was to investigate morphometric gender differences of the cerebral cortex in six males and five females, 12 to 24 years old. Though human brains lack sexual dimorphism on routine neuropathologic examinations, gender-specific brain weight, functional, and morphologic differences exist, suggesting that cortical differences may be found. Yet the cerebral cortex may be exempt from gender differences, as demonstrated by the fact that normal males and females perform comparably on intelligence tests. Stereologic morphometry on standardized histologic sections from 30 bilateral cortical loci determined cortical thickness, neuronal density, and derived neuronal number estimates. The mean ± SD cortical thickness of the 60 loci examined was similar in males and females with right and left hemispheric gender ratios being balanced. In contrast, the average neuronal density of the same 60 loci was significantly higher in the male group than in the female group, and the corresponding mean male-to-female ratios were 1.18 in the right and 1.13 in the left hemisphere, which differ significantly from each other and from the balanced cortical thickness ratios. Estimates of neuronal numbers — the product of neuronal thickness times density — were 13% higher in males than in females, with mean male-to-female ratios of 1.13 in both hemispheres. The data provide morphologic evidence of considerable cerebral cortical dimorphism with the demonstration of significantly higher neuronal densities and neuronal number estimates in males, though with similar mean cortical thickness, implying a reciprocal increase in neuropil/neuronal processes in the female cortex.

The vitamin D receptor genotype predisposes to the development of calcific aortic valve stenosis

OBJECTIVE To test the hypothesis that vitamin D receptor polymorphism is associated with calcific aortic valve stenosis. DESIGN The distribution of one polymorphism of the vitamin D receptor (BsmI B/b) was examined in 100 consecutive patients with calcific valvar aortic stenosis and compared with a control group of 100 patients (paired match for age, sex, and the presence of coronary artery disease from a total of 630 patients without calcified aortic valves). Polymerase chain reaction and restriction fragment length polymorphism were used to determine genotypes. RESULTS There was a significant difference in vitamin D receptor allele and genotype frequencies between the two groups. The allele B had a higher prevalence in patients with calcific aortic stenosis (B = 0.56, b = 0.44) than in the control cohort (B = 0.40, b = 0.60) (p = 0.001). CONCLUSIONS There is a significant association of vitamin D receptor polymorphism with calcific aortic valve stenosis. The B allele of the vitamin D receptor is more common in patients with calcific aortic valve stenosis. It now needs to be evaluated whether other genes that control calcium homeostasis are involved in the pathogenesis of this disorder.
Using annotations in enterprise search

A major difference between corporate intranets and the Internet is that in intranets the barrier for users to create web pages is much higher. This limits the amount and quality of anchor text, one of the major factors used by Internet search engines, making intranet search more difficult. The social phenomenon at play also means that spam is relatively rare. Both on the Internet and in intranets, users are often willing to cooperate with the search engine in improving the search experience. These characteristics naturally lead to considering using user feedback to improve search quality in intranets. In this paper we show how a particular form of feedback, namely user annotations, can be used to improve the quality of intranet search. An annotation is a short description of the contents of a web page, which can be considered a substitute for anchor text. We propose two ways to obtain user annotations, using explicit and implicit feedback, and show how they can be integrated into a search engine. Preliminary experiments on the IBM intranet demonstrate that using annotations improves the search quality.
6-year follow-up of 84 patients with cartilage defects in the knee

Background and purpose The natural history of focal cartilage injury is largely unknown. In this study we investigated 6-year outcomes in patients with arthroscopically verified, focal, full-thickness cartilage injuries of the knee. Methods In a previous report (baseline study) of 993 knee arthroscopies, 98 patients were less than 50 years old at baseline and showed grade 3–4 focal cartilage injury, as assessed with the International Cartilage Repair Society (ICRS) scale. In the present study, 84 of the 98 patients completed follow-ups at median 6.1 (5.3–7.8) years after baseline assessments. At baseline, the patients had undergone different types of cartilage repair (n = 34) or had no treatment or only debridement (n = 64) for their cartilage injury. The follow-up included evaluations with the ICRS knee evaluation form, the Lysholm score, and other knee evaluation tests. 68 patients underwent radiographic assessments with weight bearing. Results Improvements compared to baseline were noted in the average ICRS functional score, visual analog scale (VAS) pain score, and the patients' rating of the function in the affected knee compared to the contra-lateral knee. However, the average ICRS activity level had decreased from baseline. The average Lysholm score was 76 (SD 21). 19 patients had Kellgren-Lawrence grades 2–3 in the affected knee and 6 patients had grades 2–3 in the contralateral knee. There was a statistically significant difference between affected and contralateral knees. Interpretation Patients with arthroscopically diagnosed ICRS grade 3–4 cartilage injuries in the knee may show improvement in knee function over the following 5–8 years, with or without cartilage repair. However, knee function remains substantially affected. Further studies are needed to determine whether cartilage surgery can yield better functional outcomes than non-surgical or less invasive surgical treatments.
The efficacy of lower axillary sampling in obtaining lymph node status in breast cancer: A controlled randomized trial

Four hundred and seventeen patients with operable breast cancer treated by simple mastectomy were randomly allocated to have node sampling or total axillary clearance. There was no significant difference in the incidence of node positivity. One hundred and thirty‐five patients had node sampling and were randomized at the completion of this procedure to have axillary clearance or to have no further surgery. All node positive patients who went on to have a clearance had positive samples, confirming the accuracy of the sampling technique.
‘I’m Scunthorpe ’til I die’: Constructing and (Re)negotiating Identity through the Terrace Chant

The terrace chant, despite many varied efforts toward its control, remains a central part of many a match‐day experience. Using ethnographic data collected from Scunthorpe United Football Club over the course of the 2002/03 season, this essay explores the supporters’ utilization of songs at football matches, concentrating on the dialogic exchanges between sets of supporters. Using the insights offered by R. Jenkins, G. Armstrong and J. Bale, the paper argues that despite the modernising emphasis on placelessness present within the sport, supporters use songs to construct their own affective place‐related collective identities, whilst manipulating cultural bricolage to (re)negotiate and manage the collective identity of the other.
Depression and self-reported functional status in older primary care patients.

OBJECTIVE The authors' goal was to examine whether depression is associated with overreporting of functional disability. METHOD The subjects were 304 patients 60 years old or older who were recruited from primary care settings. Measures included examiner ratings of depression diagnosis and medical burden and self-reported and examiner-rated functional assessments. Multiple regression techniques were used to determine the independent association of depression with self-reported function after examiner-rated function was added to the analysis as a covariate. RESULTS Depression diagnosis was associated with poorer self-reported role functioning, whether the patient attributed the disability to physical or emotional causes. Depression was not independently associated with poorer self-reported physical functioning. CONCLUSIONS Clinicians and researchers should recognize that depression can confound the self-reporting and attribution of functional disability.
Species Redundancy and Ecosystem Reliability

The concept of species redundancy in ecosystem processes is troublesome because it appears to contradict the traditional emphasis in ecology on species singularity. When species richness is high, however, ecosystem processes seem clearly insensitive to considerable variation in biodiversity. Some elementary principles from reliability engineering, where engineered redundancy is a valued part of systems design, suggest that we should rethink our stance on species redundancy. For example, a central tenet of reliability engineering is that reliability always increases as redundant components are added to a system, a principle that directly supports redundant species as guarantors of reliable ecosystem functioning. I argue that we should embrace species redundancy and perceive redundancy as a critical feature of ecosystems which must be preserved if ecosystems are to function reliably and provide us with goods and services. My argument is derived from basic principles of reliability engineering which demonstrate that the probability of reliable system performance is closely tied to the level of engineered redundancy in its design. Empirical demonstrations of the value of species redundancy in ecosystem reliability would provide new insights into the ecology of communities and the value of species conservation.
Wellness for All: Improving Campus Climate for LGBTQA Students as Prevention

Abstract While it is widely recognized that campus climate can have a profound impact on students’ academic performance, mental/behavioral health, and character development, campus is not experienced equally across identity groups. For lesbian, gay, bisexual, transgender, queer, questioning, and asexual (LGBTQA) students, campus often includes added stressors, which can make college more difficult than for the average student and may negatively influence mental/behavioral health outcomes. In this article, the authors explore ways to improve campus climate as a protective factor for LGBTQA students by presenting a statewide program in Arizona with this goal. The program will be discussed within the context of addressing LGBTQA experiences in college to promote well-being.
Rate of opportunistic pap smear screening and patterns of epithelial cell abnormalities in pap smears in ajman, United arab emirates.

OBJECTIVES The aim of this study was to estimate the proportion of women undergoing Papanicolaou (Pap) smear examinations, and the frequency of epithelial cell abnormalities in a teaching hospital in one emirate of the United Arab Emirates (UAE) during a three-year period. METHODS A retrospective study of 602 patient records from July 2007 to July 2010 was done in a teaching hospital in Ajman, UAE. The variables studied were age, ethnicity, menopausal status, and abnormalities in the Pap smear. Data were analysed using the Statistical Package for the Social Sciences and presented mainly as percentages; to assess associations, the chi-square test was used. RESULTS The total number of outpatients who attended the Obstetrics & Gynaecology Department from July 2007 to July 2010 was 150,111 patients, of which 602 (0.4% of the total) had a Pap smear test. The sample was 50.1% Arabs and 49.9% other nationalities. While 73% of the outpatients had specific complaints, 27% came for a routine screening. Epithelial cell abnormalities were seen in 3.3% of the sample, with atypical squamous cells of undetermined significance (ASCUS) found in 1.8%, low-grade squamous intraepithelial lesions (LSILs) found in 1.2%, and high-grade squamous intraepithelial lesions (HSILs) found in 0.3%. There were no cases of squamous cell carcinoma. CONCLUSION Voluntary routine Pap smear screening was remarkably low in the study group. ASCUS was the most common epithelial cell abnormality. Community health education and opportunistic screening for cervical cancer are recommended for both national and expatriate women in the region.
A Reassessment of the Relationship between Inequality and Growth

This paper challenges the current belief that income inequality has a negative relationship with economic growth. It uses an improved data set on income inequality, which not only reduces measurement error, but also allows estimation via a panel technique. Panel estimation makes it possible to control for time-invariant country-specific effects, therefore eliminating a potential source of omitted-variable bias. Results suggest that in the short and medium term, an increase in a country's level of income inequality has a significant positive relationship with subsequent economic growth. This relationship is highly robust across samples, variable definitions, and model specifications.
Mother-to-child HIV transmission despite antiretroviral therapy in the ANRS French Perinatal Cohort

Objective:To identify factors associated with mother-to-child HIV-1 transmission (MTCT) from mothers receiving antenatal antiretroviral therapy. Design:The French Perinatal Cohort (EPF), a multicenter prospective cohort of HIV-infected pregnant women and their children. Methods:Univariate analysis and logistic regression, with child HIV status as dependent variable, were conducted among 5271 mothers who received antiretroviral therapy during pregnancy, delivered between 1997 and 2004 and did not breastfeed. Results:The MTCT rate was 1.3% [67/5271; 95% confidence interval (CI), 1.0–1.6]. It was as low as 0.4% (5/1338; 95% CI, 0.1–0.9) in term births with maternal HIV-1 RNA level at delivery below 50 copies/ml. MTCT increased with viral load, short duration of antiretroviral therapy, female gender and severe premature delivery: 6.6% before 33 weeks versus 1.2% at 37 weeks or more (P < 0.001). The type of antiretroviral therapy was not associated with transmission. Intrapartum therapy was associated with four-fold lower MTCT (P = 0.04) in case of virological failure (> 10 000 copies/ml). Elective cesarean section tended to be inversely associated with MTCT in the overall population, but not in mothers who delivered at term with viral load < 400 copies/ml [odds ratio (OR), 0.83; 95% CI, 0.29–2.39; P = 0.37]. Among them, only duration of antenatal therapy was associated with transmission (OR by week, 0.94; 95% CI, 0.90–0.99; P = 0.03). Conclusions:Low maternal plasma viral load is the key factor for preventing MTCT. Benefits in terms of MTCT reduction may be expected from early antiretroviral prophylaxis. The potential toxicity of prolonged antiretroviral use in pregnancy should be evaluated.
Delay of Gratification among Black College Student Leaders

The purpose of this research was to examine the existence of multidimensionality in delay of gratification for Black university student leaders. We investigated delay preference as it related to academic decisions, career choices, sociopolitical issues, and consumer preferences. Results supported such multidimensionality by yielding evidence for the heretofore unexamined sociopolitical dimension as well as an achievement-oriented delay dimension in this sample of Black students. Gender differences are also reported. Results indicated that similar factor structures emerged for both sexes. The importance of this approach to the study of delay is discussed as well as directions for future research.
A Longitudinal Test of a Model of Academic Success for At–Risk High School Students

ABSTRACT Whereas previous researchers have described at–risk students' deficiencies, in the present study their academic success was investigated. Longitudinal data from 8,100 high school students participating in a national study were used to test a model of at–risk students' school learning. The results indicated that ability, quality of schooling, student motivation, and academic coursework are important predictors of academic achievement. Although the present findings indicate that student motivation may have a stronger impact on at–risk students' achievement than on the achievement of high school students in general, overall school learning influences appear very similar to those found for high school students in general.
The Impact of Subject Matter on Curricular Activity: An Analysis of Five Academic Subjects

This article tests a framework connecting features of subject matter with curricular activities among high school teachers of five academic subjects. Using survey responses, it compares the conceptions of subject matter (defined, static, sequential) and curricular activities (coordination, coverage, consensus on content, standardization, course rotation, etc.) of English, social studies, science, math, and foreign language teachers from 16 high schools. Teachers differ in their perceptions of their subjects as defined, sequential, and static. For example, math and foreign language teachers score higher on those features than other teachers. In turn, certain curricular activities seem to differ depending on subject features. For example, in sequential subjects, teachers report more coordination with colleagues and more press for coverage of content than in less sequential subjects. Implications for research and policy are presented.
The Workplace as a Context for Cross-Cutting Political Discourse

Political dialogue among citizens offers numerous potential contributions to American politics, but attainment of these benefits hinges largely on the extent to which conversations cross lines of political difference. In what contexts are cross-cutting interactions most likely to thrive? Using data from five surveys, we find consistent evidence that the workplace is the social context best positioned to facilitate cross-cutting political discourse. Political discussion in the workplace involves a large number of discussants, and it involves greater exposure to people of dissimilar perspectives than does discussion in contexts such as the family, the neighborhood, or the voluntary association. We next consider whether workplace-based interactions are capable of producing beneficial effects. Despite the notoriously weak nature of work-based social ties, we find evidence that workplace-based exposure to differing political views increases people's knowledge of rationales for political perspectives other than their own and also fosters political tolerance.
