A Community of Curious Souls: An Analysis of Commenting Behavior on TED Talks Videos

The TED (Technology, Entertainment, Design) Talks website hosts video recordings of various experts, celebrities, academics, and others who discuss their topics of expertise. Funded by advertising and members but provided free online, TED Talks have been viewed over a billion times and are a science communication phenomenon. Although the organization has been derided for its populist slant and emphasis on entertainment value, no previous research has assessed audience reactions in order to determine the degree to which presenter characteristics and platform affect the reception of a video. This article addresses this issue via a content analysis of comments left on both the TED website and the YouTube platform (on which TED Talks videos are also posted). It was found that commenters were more likely to discuss the characteristics of a presenter on YouTube, whereas commenters tended to engage with the talk content on the TED website. In addition, people tended to be more emotional when the speaker was a woman (by leaving comments that were either positive or negative). The results can inform future efforts to popularize science amongst the public, as well as to provide insights for those looking to disseminate information via Internet videos.
MiR-125a-3p Regulates Glioma Apoptosis and Invasion by Regulating Nrg1

The current study was designed to examine the functional role and mechanism of miR-125a-3p in glioma development. Quantitative RT-PCR was used to evaluate miR-125a-3p expression in 60 glioma cases of different malignant grades. Then, the clinic pathologic significance of miR-125a-3p expression was determined in combination with the prognosis of the patients. In addition, the effects and mechanisms of miR-125a-3p on the proliferation, apoptosis and invasion of glioma cells were further investigated. The results showed that the expression of miR-125a-3p was decreased significantly in most malignant glioma samples relative to normal brain tissues and glioma tissues of low-malignant degree. Further kaplan-meier survival analysis showed that the lower expression of miR-125a-3p was associated with a poor prognosis of GBM patients. Functional analysis showed that the reintroduction of miR-125a-3p into glioblastoma cell lines induces markedly the apoptosis and suppresses the proliferation and migration of glioblastoma cells in vitro and in vivo. Luciferase assay and Western blot analysis revealed that Nrg1 is a direct target of miR-125a-3p. Furthermore, an increased expression of Nrg1 could reverse the effects of overexpression of miR-125a-3p on the proliferation, apoptosis and migration of glioblastoma cells. These findings suggest that miR-125a-3p performed an important role in glioma development mediated by directly regulating the expression of Nrg1. This study also provides a potential target for diagnosis and treatment of malignant glioma.
Rule change and Olympic judo scores, penalties and match duration

Abstract In judo, between 2009 and 2013, many changes were added, especially after London 2012 Olympics to promote “positive” actions/score instead of “negative” actions/penalties. This study compared the total match duration, frequency of scores (ippon, wazari, yuko) and penalties (shido) between Rio 2016 and London 2012 (before and after rules change), considering weight categories and competition phases. Data from 470 male athletes and 307 female athletes who disputed, respectively, 1022 and 698 matches in both Olympic Games were analysed. Three-way ANOVA was used to compare sexes, weight categories, Olympic Games edition, with Tukey test as post hoc. The association between Olympic Games edition and percentage of matches without any score was tested via Chi-square and Cramer’s – V effect size was used. Significance level was set at 5%. Eta squared (η2) was used as effect size. Results (Rio 2016 vs. London 2012) suggest in no change in ippon and wazari scores, while decreasing the number of yuko and increasing the number of penalties. Females scored more yuko and received less penalties than males. Females matches in Rio were shorter than matches for all other groups. For scores and penalties, no difference was found concerning weight categories, but half-heavyweight matches were shorter than lightweight ones.
Developing social and decisional capital in US National Blue Ribbon Schools

The US National Blue Ribbon Schools (NBRS) Program annually recognizes hundreds of schools successful in their states’ accountability systems. NBRS are studied for effective practices worth replicating. In this study, 2016 NBRS Program applications (n = 24) yielded insight about espoused collaborative practices, providing information about the development of social and decisional capital. Leaders strategically allocated time and structures and created systems. Furthermore, relational conditions, such as a culture of teamwork and building trusting relationships were instrumental. Empowerment conditions, such as leaders trusting teachers and valuing their input, as well as providing them opportunities for decision-making and leadership, also supported the development of social and decisional capital.
Drop Testing Of Printed Wiring Assemblies

This paper is part of an ongoing effort to develop a test methodology to examine the durability of surface mount interconnects under impact loading conditions. Literature indicates that as the drop height is increased, there is a transition in the failure site from the ductile solder to the brittle intermetallic or the copper traces. Not much work has been done to understand this phenomenon. This study considers deformation energy accumulated in the interconnects in terms of the local strain in the printed wiring assembly (PWA), local strain rate and component acceleration. The advantage is that the results are less dependant on structure and loading, because the deformation is quantified in terms of specimen response rather than the loading conditions. A simple test specimen is fabricated to concentrate the study on interconnect failure mechanisms. An instrumented, repeatable test setup is developed to conduct high speed bend tests and drop tests on the specimen. All tests are replicated twice for proof of consistency of the test data. The paper describes the test setup in detail and presents the results of the high speed bend tests. As expected, the durability of the specimen decreases monotonically with PWA strain. On the other hand, the durability first increases and then decreases as the PWA strain rate increases. Failure analysis shows a transition in the failure site with strain rate. It is hypothesized that for a given package design, the rate dependent material properties determine the partitioning of the strain energy of deformation. Yield stress of the ductile materials and fracture toughness of the brittle materials are identified as the key parameters. More tests are needed to understand this rate dependent strain energy partitioning. The end goal is to develop a consistent, accurate and generic methodology for ranking the impact durability of different surface mount interconnects technologies.
Algerian EFL University Teachers’ Attitudes towards Computer Assisted Language Learning: The Case of Djilali Liabes University

Computer Assisted Language Learning (CALL) is still groping its way into Algerian English as a Foreign Language (EFL) classroom, where Information Communications Technologies (ICTs) are defined in terms of occasional use of computers and data projectors for material presentation in the classroom. Though major issues in the image of the lack of training and absence of facilities are clearly apparent, stakeholders’ attitudes are a decisive aspect that needs to be mapped out if we are to alter the current situation. Thus, the present work aims at investigating EFL university teachers’ attitudes towards CALL at Djilali Liabes University (western Algeria). The current work is a cross-sectional descriptive study that explores teachers’ attitudes across the three domains (affective, cognitive, and behavioural) and investigates other related aspects that may help indicate teachers’ likelihood to adopt CALL in the future. The results are promising as the investigated population not only demonstrated a clearly positive attitude towards CALL but also manifested a number of signs that indicate their likelihood to adopt CALL in the future if circumstances are favourable.
THE STAR FORMATION AND NUCLEAR ACCRETION HISTORIES OF NORMAL GALAXIES IN THE AGES SURVEY

We combine IR, optical, and X-ray data from the overlapping, 9.3 deg2 NOAO Deep Wide-Field Survey, AGN and Galaxy Evolution Survey (AGES), and XBoötes Survey to measure the X-ray evolution of 6146 normal galaxies as a function of absolute optical luminosity, redshift, and spectral type over the largely unexplored redshift range 0.1 ≲ z ≲ 0.5. Because only the closest or brightest of the galaxies are individually detected in X-rays, we use a stacking analysis to determine the mean properties of the sample. Our results suggest that X-ray emission from spectroscopically late-type galaxies is dominated by star formation, while that from early-type galaxies is dominated by a combination of hot gas and active galactic nucleus (AGN) emission. We find that the mean star formation and supermassive black hole accretion rate densities evolve like ∼(1 + z)3±1, in agreement with the trends found for samples of bright, individually detectable starburst galaxies and AGN. Our work also corroborates the results of many previous stacking analyses of faint source populations, with improved statistics.

Mass spectrometry-based metabolomics of single yeast cells

Single-cell level measurements are necessary to characterize the intrinsic biological variability in a population of cells. In this study, we demonstrate that, with the microarrays for mass spectrometry platform, we are able to observe this variability. We monitor environmentally (2-deoxy-d-glucose) and genetically (ΔPFK2) perturbed Saccharomyces cerevisiae cells at the single-cell, few-cell, and population levels. Correlation plots between metabolites from the glycolytic pathway, as well as with the observed ATP/ADP ratio as a measure of cellular energy charge, give biological insight that is not accessible from population-level metabolomic data.
The Chemical Composition of the Galactic Bulge and Implications for its Evolution

Abstract At a bulge latitude of b = −4°, the average [Fe/H] and [Mg/H] values are +0.06 and +0.17 dex, roughly 0.2 and 0.7 dex higher than the local thin and thick disk values, respectively, suggesting a large bulge effective yield, perhaps due to efficient retention of supernova ejecta. The bulge vertical [Fe/H] gradient, at ~ 0.5 dex/kpc, appears to be due to a changing mixture of sub-populations (near +0.3 dex and −0.3 dex and one possibly near −0.7 dex) with latitude. At solar [Fe/H], the bulge [Al/Fe] and [α/Fe] ratios are ~ +0.15 dex. Below [Fe/H] < ! [CDATA[$ ~ −0.5 dex, the bulge and local thick disk compositions are very similar; but the measured [Mg/Fe], [⟨SiCaTi⟩/Fe], [La/Eu] and dramatic [Cu/Fe] ratios suggest higher SFR in the bulge. However, these composition differences with the thick disk could be due to measurement errors and non-LTE effects. Unusual zig-zag trends of [Cu/Fe] and [Na/Fe] suggest metallicity-dependent nucleosynthesis by core-collapse supernovae in the Type Ia supernova time-delay scenario. The bulge sub-population compositions resemble the local thin and thick disks, but at higher [Fe/H], suggesting a radial [Fe/H] gradient of − $0.04]] > to − 0.05 dex/kpc for both the thin and thick disks. If the bulge formed through accretion of inner thin and thick disk stars, it appears that these stars retained vertical scale heights characteristic of their kinematic origin, resulting in the vertical [Fe/H] gradient and [α/Fe] trends seen today.
Synopsis: An analysis of trends and determinants of child undernutrition in Ethiopia, 2000-2011

This study uses two rounds of the Ethiopian Demographic Health Survey (EDHS) to statistically analyze patterns and trends in undernutrition (child growth) in Ethiopia over the period 2000 to 2011. In 2000, over half of Ethiopian preschool children were stunted and almost a third were severely stunted. However, progress against child undernutrition over the study period was solid, with stunting prevalence reduced by 1.4 percentage points per year, although progress has slowed since to 1.0 points per year between 2011 and 2014.
Item Recognition as a Performance Evaluation Test for Environmental Research

Item Recognition (Sternberg, 1966) is a task which reflects the operation of human memory. This task was considered as a candidate for use in a battery of Performance Evaluation Tests for Environmental Research (PETER). Environmental research involves comparison of performances in a baseline environment and in a novel environment. It is desirable that scores be stable at different occasions in the baseline environment, so that changes due to the novel environment will be clear if they occur. It was found that item recognition results were similar to those obtained by other investigations, although the traditional item recognition score (slope) was unreliable across repeated measurements. The response time (RT) was stable for each of the four memory set sizes (1, 2, 3 & 4 items), from the standpoint of reliability, after the fourth session.
Human Infants' Perception of Auditory Patterns

Human infants' perception of tone sequences or melodies is reviewed the context of related work with human adults and nonhuman species. For the part, infants use an adult-like pitch processing strategy that is global and rather than the local pitch strategy that is characteristic of the nonhuman species stud date. Thus they encode and retain the pitch configuration or contour of with little attention to the absolute pitches of individual notes. In the case structured melodies, specifically, melodies that are prototypical of Western music, in encode more precise relations, notably the intervals or exact pitch relations be adjacent notes. Finally, the functional significance of relational pitch in human infancy is considered processing tween fants of well a melody, ied to relational most in
A global phylogeny of Pelomedusoides turtles with new material of Neochelys franzeni Schleich, 1993 (Testudines, Podocnemididae) from the middle Eocene, Messel Pit, of Germany

Background. Neochelys franzeni Schleich, 1993 is the only pleurodire or side-necked turtle from the middle Eocene, Messel Pit (the first UNESCO, World Natural Heritage Site in Germany, since 1995). The original description of the species is based on two specimens SMF ME 1091 (Holotype) and 715 (Paratype) housed at the Senckenberg Museum Frankfurt. The excellent preservation of complete and articulated skeletons of this species makes it a key taxon for understanding the evolution and phylogeny of the European Neochelys genus and its relationships with South American and African-Madagascar podocnemidids. Results. Five new specimens of Neochelys franzeni from Messel Pit are described here, together with the redescription of SMF ME 1091 and 715. Specimens correspond to individuals of different ontogenetic stages showing conservative morphology from hatching to adults. A revised diagnosis for the species is presented here, together with its inclusion in a global phylogenetic analysis of Pelomedusoides that shows that this species and the whole Neochelys spp. is sister to the Erymnochelys madagascariensis-Peltocephalus dumerilianus clade within Podocnemididae.
The number of graphs and a random graph with a given degree sequence

We consider the set of all graphs on n labeled vertices with prescribed degrees D = (d1,…,dn). For a wide class of tame degree sequences D we obtain a computationally efficient asymptotic formula approximating the number of graphs within a relative error which approaches 0 as n grows. As a corollary, we prove that the structure of a random graph with a given tame degree sequence D is well described by a certain maximum entropy matrix computed from D. We also establish an asymptotic formula for the number of bipartite graphs with prescribed degrees of vertices, or, equivalently, for the number of 0‐1 matrices with prescribed row and column sums. © 2012 Wiley Periodicals, Inc.

Role of a GntR-Family Response Regulator LbrA in Listeria monocytogenes Biofilm Formation

The formation of Listeria monocytogenes biofilms contributes to persistent contamination in food processing facilities. A microarray comparison of L. monocytogenes between the transcriptome of the strong biofilm forming strain (Bfms) Scott A and the weak biofilm forming (Bfmw) strain F2365 was conducted to identify genes potentially involved in biofilm formation. Among 951 genes with significant difference in expression between the two strains, a GntR-family response regulator encoding gene (LMOf2365_0414), designated lbrA, was found to be highly expressed in Scott A relative to F2365. A Scott A lbrA-deletion mutant, designated AW3, formed biofilm to a much lesser extent as compared to the parent strain by a rapid attachment assay and scanning electron microscopy. Complementation with lbrA from Scott A restored the Bfms phenotype in the AW3 derivative. A second microarray assessment using the lbrA deletion mutant AW3 and the wild type Scott A revealed a total of 304 genes with expression significantly different between the two strains, indicating the potential regulatory role of LbrA in L. monocytogenes. A cloned copy of Scott A lbrA was unable to confer enhanced biofilm forming potential in F2365, suggesting that additional factors contributed to weak biofilm formation by F2365.
The North Carolina Outward Bound School Course Impression Survey: A Psychometric Investigation

This study investigated the development and psychometric properties of the North Carolina Outward Bound School Course Impression Survey (NCOBSCIS). The NCOBSCIS measures character development, leadership, and environmental service, and was adapted from the previously established Outward Bound Outcomes Instrument (OBOI). The purpose of this study was to both conduct a psychometric evaluation of the NCOBSCIS and to also describe the processes that were used to develop and validate a series of outcome measures. These processes are applicable to other programs interested in measuring participant outcomes.

Drinking male tears: language, the manosphere, and networked harassment

Abstract While popular discourse often frames online harassment as an issue of individuals engaged in abhorrent behavior, harassing behavior is often networked in that it is coordinated and organized. When feminists and female public figures experience harassment, it often originates from members of a loose online network known as the manosphere, a set of blogs, podcasts, and forums comprised of pickup artists, men’s rights activists, anti-feminists, and fringe groups. While the particular beliefs of these groups may differ, many participants have adopted a common language. This paper explores the discourse of the manosphere and its links to online misogyny and harassment. Using critical discourse analysis, we examine the term misandry, which originates in the manosphere; trace its infiltration into more mainstream circles; and analyze its ideological and community-building functions. We pay particular attention to how this vocabulary reinforces a misogynistic ontology which paints feminism as a man-hating movement which victimizes men and boys.
Evaluation of Solo Vocal Performance: A Comparison of Students with Experts

The ability to evaluate performance with reliability and validity IS an asset to any music teacher. It is a sine qua non for music exams and auditions, if there is to be any meaningful assessment of students' achievement and potential. Moreover, during every music lesson, teachers continuously evaluate students' performance to make necessary adjustments in their students' technique and in their own teaching methods. Reliable and valid evaluation gives students valuable feedback on their progress toward the attainment of professional standards and helps to clarify their immediate and long-term goals. There is, furthermore, much anecdotal evidence that acquiring a clear idea of professional standards may have a positive effect on performance by providing students with an auditory image of the sound quality they are striving to produce. The writings of voice pedagogues from Tosi (1723) to Gunter (1992) contain exhortations to novice singers to listen to the best examples of vocal artistry to develop their "concept of tone beauty in the mind" (Enrico Caruso, cited in Cooke, 1952). The ability to evaluate may thus be valuable to students, not only as future teachers but also as performers. A number of studies have examined evaluation of musical performance (Duerksen, 1972; Radocy, 1975, 1976; Fiske, 1977a, 1977b; Burnsed, Hinkle, & King, 1985; Tunks, 1987; Boyle, 1992; Wapnick, Flowers, Alegant & Jasinskas, 1993). Very little research, however, has dealt specifically with solo vocal performance. Jones (1986) used facet-factorial analysis to construct a 32-item rating scale for evaluation of high
