Sociolinguistic diversity in mainstream media: Authenticity, authority and processes of mediation and mediatization

This article explores the attribution of authority and authenticity to speakers of “accented” or dialectal speech portrayed in the American documentary on dialectal diversity, “Do You Speak American? ”. The focus is on the role of mediation and mediatization in this fundamentally political and ideological process: that is, the extent to which particular sequences of the documentary foreground the work of representation being done by media producers. The central claim made in the analysis is that speakers’ authenticity is produced through the backgrounding of this work of representation, but that speakers are attributed greater authority when they are depicted as having some control over how their images and speech are mediated and mediatized. Speakers who have both authority and authenticity benefit, it is argued, from media verisimilitudes: they are understood by media audiences as having control over the believable rather than the “real”.
Rhythms and outcomes of adult in-hospital cardiac arrest*

Objective:To determine the relationship of electrocardiographic rhythm during cardiac arrest with survival outcomes. Design:Prospective, observational study. Setting:Total of 411 hospitals in the National Registry of Cardiopulmonary Resuscitation. Patients:Total of 51,919 adult patients with pulseless cardiac arrests from April 1999 to July 2005. Measurements and Main Results:Registry data collected included first documented rhythm, patient demographics, pre-event data, event data, and survival and neurologic outcome data. Of 51,919 indexed cardiac arrests, first documented pulseless rhythm was ventricular tachycardia (VT) in 3810 (7%), ventricular fibrillation (VF) in 8718 (17%), pulseless electrical activity (PEA) in 19,262 (37%) and asystole 20,129 (39%). Subsequent VT/VF (that is, VT or VF occurring during resuscitation for PEA or asystole) occurred in 5154 (27%), with first documented rhythm of PEA and 4988 (25%) with asystole. Survival to hospital discharge rate was not different between those with first documented VF and VT (37% each, adjusted odds ratio [OR]) 1.08; 95% confidence interval [CI] 0.95–1.23). Survival to hospital discharge was slightly more likely after PEA than asystole (12% vs. 11%, adjusted OR 1.1; 95% CI 1.00–1.18), Survival to discharge was substantially more likely after first documented VT/VF than PEA/asystole (adjusted OR 1.68; 95% CI 1.55–1.82). Survival to discharge was also more likely after PEA/asystole without subsequent VT/VF compared with PEA/asystole with subsequent VT/VF (14% vs. 7% for PEA without vs. with subsequent VT/VF; 12% vs. 8% for asystole without vs. with subsequent VT/VF; adjusted OR 1.60; 95% CI, 1.44–1.80). Conclusions:Survival to hospital discharge was substantially more likely when the first documented rhythm was shockable rather than nonshockable, and slightly more likely after PEA than asystole. Survival to hospital discharge was less likely following PEA/asystole with subsequent VT/VF compared to PEA/asystole without subsequent VT/VF.
PBOV1 promotes prostate cancer proliferation by promoting G1/S transition

Prostate cancer (PC) is one of the leading causes of cancer death in men, and thus, finding new regulators is critical for PC therapy. Prostate and breast cancer overexpressed 1 (PBOV1) is overexpressed in breast, prostate, and bladder cancers, as it is upregulated in the serum of patients with PC, but the role of PBOV1 in PC has not been studied. In this article, we found that PBOV1 was indeed overexpressed in PC cells; PBOV1 overexpression promoted cell proliferation and colony formation ability and arrested cell cycle in the G0/G1 phase and tumorigenicity ability in vitro, whereas knockdown of PBOV1 reduced these effects. Further analysis of PBOV1 overexpression inhibited cell cycle inhibitors, P21 and P27, and increased the phosphorylation level of Rb and cyclin D1 expression, suggesting that PBOV1 promoted cell proliferation through promoting G1/S transition.
Multi-view (Joint) probability linear discrimination analysis for J-vector based text dependent speaker verification

J-vector has been proved to be very effective in text dependent speaker verification with short-duration speech. However, the current back-end classifiers cannot make full use of such deep features. In this paper, we propose a method to model the multi-faceted information in the j-vector explicitly and jointly. Examples of the multi-faceted information include speaker identity and text content. In our approach, the j-vector was modeled as a result derived by a generative multi-view (joint1) Probability Linear Discriminant Analysis (PLDA) model, which contains multiple kinds of latent variables. The usual PLDA model only considers one single label. However, in practical use, when using multi-task learned network as feature extractor, the extracted feature are always associated with several labels. This type of feature is called multi-view deep feature (e.g. j-vector). With multi-view (joint) PLDA, we are able to explicitly build a model that can combine multiple heterogeneous information from the j-vectors. In verification step, we calculated the likelihood to describe whether the two j-vectors having consistent labels or not. This likelihood is used in the following decision-making. Experiments have been conducted on large scale data corpus of different languages. On the public RSR2015 data corpus, the results showed that our approach can achieve 0.02% EER and 0.09% EER for impostor wrong and impostor correct cases respectively.
Recherche approximative de plus proches voisins avec contrôle probabiliste de la précision ; application à la recherche d'images par le contenu. (Approximate search of nearest neighbors with probabilistic control of the accuracy; application to content-based image retrieval)

Cette these s'interesse aux systemes de recherche d'images par le contenu, ou le but est de rechercher les images les plus similaires a une image requete fournie en exemple. Pour cela, il est d'abord necessaire de decrire les images stockees dans la base. L'objectif est de traduire la similarite visuelle entre images en une simple notion de proximite spatiale entre descripteurs. Ainsi, pour retrouver les images similaires a l'image requete, il suffit de retrouver les descripteurs les plus proches du descripteur de l'image requete. Ce mode de recherche, appele recherche de plus proches voisins, est cependant extremement couteux meme lorsque les techniques s'indexation multidimensionnelles sont utilisees. Les performances de celles-ci se degradent exponentiellement lorsque la dimension des descripteurs augmente (phenomene de la malediction de la dimension). Il s'avere toutefois que l'on peut fortement reduire le cout de ces recherches en effectuant des recherches approximatives. Le principe est alors de negocier une reduction du temps de reponse contre l'introduction d'imprecisions durant la recherche. Ce travail reprend ce principe et propose une nouvelle methode de recherche approximative de plus proches voisins qui permet un controle fin et intuitif de la precision de la recherche. Ce controle s'exprime au travers d'un seul parametre qui indique la probabilite maximale de ne pas trouver un des plus proches voisins recherches. Dans le but d'evaluer rigoureusement ses performances dans le cadre d'un systeme reel, la methode proposee a ete ensuite integree dans un systeme de recherche d'images pour la detection de copies. Les experimentations effectuees montrent que la methode proposee est efficace, fiable et son imprecision n'a qu'un impact mineur sur la qualite des resultats finaux.
Motivation and Disinhibition in High Risk Sports: Sensation Seeking and Self-Efficacy

Abstract This study examined the roles of sensation seeking and self-efficacy in explaining extreme and high physical risk taking behavior. Study participants were 20 extreme risk takers chosen from participants in skiing, rock climbing, kayaking, and stunt flying. One control group was comprised of 20 high, but not extreme, risk takers from each of these activities, matched to the participants in skill and experience. A second control group consisted of 20 trained athletes involved in moderate risk sports. Percepts of self-efficacy emerged as the principle variable differentiating the groups. A social cognitive explanation for desire for mastery was used to understand what enables risk takers to overcome the potentially inhibiting influences of anxiety, fear, and the recognition of danger. This conclusion is further reinforced by converging results from interviews with the participants.

New uncertainty principles for the continuous Gabor transform and the continuous wavelet transform

Gabor and wavelet methods are preferred to classical Fourier methods, whenever the time dependence of the analyzed sig- nal is of the same importance as its frequency dependence. However, there exist strict limits to the maximal time-frequency resolution of these both transforms, similar to Heisenberg's uncertainty principle in Fourier analysis. Results of this type are the subject of the following article. Among else, the following will be shown: if is a window function, f 2 L 2 (R) n f0g an arbitrary signal and G f(! ;t) the con- tinuous Gabor transform of f with respect to , then the support of G f(! ;t) considered as a subset of the time-frequency-plane R 2 can- not possess nite Lebesgue measure. The proof of this statement, as well as the proof of its wavelet counterpart, relies heavily on the well known fact that the ranges of the continuous transforms are reproduc- ing kernel Hilbert spaces, showing some kind of shift-invariance. The last point prohibits the extension of results of this type to discrete theory.
Effects of leadership style and anonymity on group potency and effectiveness in a group decision support system environment.

A longitudinal laboratory experiment was conducted to evaluate the effects of leadership style (transactional vs. transformational) and anonymity level (identified vs. anonymous) on group potency and effectiveness of 36 undergraduate student work groups performing a creativity task using a Group Decision Support System (GDSS). GDSS are interactive networks of computers for generating solutions to unstructured problems. Results indicated that GDSS anonymity amplified the positive effect of transformational leadership on group potency relative to transactional leadership in the group writing session of the task. GDSS anonymity also increased the effect of transformational leadership relative to transactional leadership on group effectiveness. Implications for practice and future research are discussed.
Robust face pose classification method based on geometry-preserving visual phrase

Constructing the discriminative feature for face pose classification is challenging. Since the key facial points are co-occurring with different spatial layout in different poses, we propose a pose classification framework based on the local geometry-preserving visual phrase (GVP). The weighting strategy on GVP enhances the discriminability of the single word and the spatial layout in the high order phrase simultaneously. Thus, the co-occurring words and local geometric structure of phrase are discriminative to distinguish pose, flexible and robust to the multi-factor variations. The experimental results on Oriental Face database and PIE database show the superiority of our method compared with the PCA, LDA based methods and the tf-idf weighted BoW method.
Oocyte Maturation in Assisted Reproductive Techniques

Abstract: Human oocyte maturation is a long process during which nuclear maturation occurs resulting in germinal vesicle breakdown (transition from prophase I to metaphase II) and extrusion of the first polar body. During oocyte maturation, in parallel with nuclear maturation, a number of events take place in the oocyte cytoplasm that assist fertilization and early embryonic development. So far several attempts have been made to mature human oocytes in vitro. The main patient group to which in vitro maturation (IVM) has been applied is polycystic ovarian syndrome. In a concise review we present the techniques used for the IVM of oocytes and the role of hormones and growth factors in IVM and subsequent fertilization and early embryonic development.
Incorporating Linguistic Knowledge for Learning Distributed Word Representations

Combined with neural language models, distributed word representations achieve significant advantages in computational linguistics and text mining. Most existing models estimate distributed word vectors from large-scale data in an unsupervised fashion, which, however, do not take rich linguistic knowledge into consideration. Linguistic knowledge can be represented as either link-based knowledge or preference-based knowledge, and we propose knowledge regularized word representation models (KRWR) to incorporate these prior knowledge for learning distributed word representations. Experiment results demonstrate that our estimated word representation achieves better performance in task of semantic relatedness ranking. This indicates that our methods can efficiently encode both prior knowledge from knowledge bases and statistical knowledge from large-scale text corpora into a unified word representation model, which will benefit many tasks in text mining.
Differential mRNA expression of nutrient transporters in male and female chickens

ABSTRACT Male chickens grow faster than female chickens, which may be due to greater nutrient uptake. The transport of nutrients from the intestine to the blood is mediated by transporters located on the surface of epithelial cells lining the villi. The objective of this study was to profile the mRNA expression of an aminopeptidase and selected amino acid and monosaccharide transporters in the duodenum, jejunum, and ileum of male and female chickens at d of hatch (doh) and at d 7 and d 14 post hatch. The mRNA abundance of aminopeptidase N (APN), a peptide (PepT1), 6 amino acid transporters (ASCT1, bo,+AT, CAT1, EAAT3, LAT1, and y+LAT2), and 3 monosaccharide (GLUT2, GLUT5, and SGLT1) transporters was assayed by real‐time PCR. Data were analyzed by ANOVA using JMP Pro11. The abundance of bo,+AT, EAAT3, ASCT1, y+LAT2, and GLUT2 mRNA was greater in male than female chickens (P < 0.05). There was no difference in expression between males and females for the other 5 transporters and APN. There was a sex x age interaction for bo,+AT, PepT1, SGLT1, ASCT1, and y+LAT2 mRNA, with greater mRNA abundance in males than females at doh but no difference between males and females at d 7 and d 14. A 3‐way sex x age x tissue interaction was observed for GLUT2 mRNA. There was greater GLUT2 mRNA abundance for males in the duodenum and ileum at doh and in the jejunum at d 7, but no difference between males and females at d 14. Thus, there was differential expression of some nutrient transporters in male and female chicks at doh but not at later ages.
LOW LEVEL IMPEDANCE CHANGES FOLLOWING THE SPIKE IN THE SQUID GIANT AXON BEFORE AND AFTER TREATMENT WITH "VERATRINE" ALKALOIDS

The increase in conductance, which accompanies the spike in the presence of sea water, is followed by a decrease to below the resting level, here designated as the "initial after-impedance," which lasts 3 msec. and is 3 per cent as great as the increase. Treatment with cevadine usually obliterates the latter but leaves the former essentially unaltered. In addition, the alkaloid gives rise to periodic conductance increases followed by a prolonged, exponentially decaying elevated conductance (the "negativity after-impedance") which correspond closely to potential oscillations and to the negative after-potential. These are also only a few per cent of the major conductance change. Veratridine causes a conductance increase which lasts longer and which also conforms closely with earlier after-potential results. Preliminary calculations indicate that the negativity after-impedance and the negative after-potential may be due to the subsidence of an elevated chloride permeability. However, no satisfactory explanation is available for the initial after-impedance or for the temporal course of the conductance changes associated with oscillations in membrane potential.
Distance and Social Recognition in Hens: Implications for the Use of Photographs as Social Stimuli

The role of close (less than 30 cm) examination or scrutiny of other birds in social recognition was confirmed by showing that before approaching a hen whose identity was unknown, hens behaved similarly whether that bird was familiar or unfamiliar to them, but after examining the other hen they temporarily kept further away from unfamiliar hens (Expt 1). Hens chose flock-mates rather than unfamiliar birds as feeding companions even when all that was visible of the target birds were their heads and necks, confirming the role of these regions in recognition (Expt 2). They showed this preference for familiar birds whether they could see either the front or the side views of the heads of the target birds but attempts to confirm this result with photographs rather than live birds resulted in no significant preference being shown (Expts 3 and 4). The reasons for this lack of transfer from live birds to photographs and its implications for presenting artificial visual stimuli such as photographs and video to hens are discussed.
ISSP position stand: To test or not to test? The use of physical skill tests in talent detection and in early phases of sport development

Abstract Searching for talent and the assessing ability in young prospects from individual and team sports often include measurement, analysis, and evaluation of physical and motor skills. The use of these tests in early stages of talent development has been widely observed in both female and male prospects. The purpose of this paper is to review a series of studies conducted on talented and less‐talented athletes/players that were aimed at distinguishing between the two groups and at predicting the athletes'/players’ future achievements/success. Thirteen studies examining the use of physical and motor skill tests in young prospects are reviewed. Based on this review, four main observations are highlighted and a number of benefits and limitations associated with the use of such tests are discussed. It is recommended that (1) coaches reduce the number of batteries of physical and motor skill tests used in early phases of talent development and (2) coaches and sport scientists specializing in measurement and evaluation cooperate in order to improve the effectiveness of the application and interpretation of physical skill tests given to prospects at early stages of talent development
Behavioral/systems/cognitive Effective Connectivity Determines the Nature of Subjective Experience in Grapheme-color Synesthesia

Synesthesia provides an elegant model to investigate neural mechanisms underlying individual differences in subjective experience in humans. In grapheme–color synesthesia, written letters induce color sensations, accompanied by activation of color area V4. Competing hypotheses suggest that enhanced V4 activity during synesthesia is either induced by direct bottom-up cross-activation from grapheme processing areas within the fusiform gyrus, or indirectly via higher-order parietal areas. Synesthetes differ in the way synesthetic color is perceived: " projector " synesthetes experience color externally colocalized with a presented grapheme, whereas " associators " report an internally evoked association. Using dynamic causal modeling for fMRI, we show that V4 cross-activation during synesthesia was induced via a bottom-up pathway (within fusiform gyrus) in projector synesthetes, but via a top-down pathway (via parietal lobe) in associators. These findings show how altered coupling within the same network of active regions leads to differences in subjective experience. Our findings reconcile the two most influential cross-activation accounts of synesthesia.
Cerebral white matter fractional anisotropy and tract volume as measured by MR imaging are associated with impaired cognitive and motor function in pediatric posterior fossa tumor survivors

Disease and therapy cause brain damage and subsequent functional loss in pediatric patients with posterior fossa tumors. Treatment‐related toxicity factors are resection in patients with pilocytic astrocytoma (PA) and, additionally, cranio‐spinal irradiation together with chemotherapy in patients with medulloblastoma (MB). We tested whether damage to white matter (WM) as revealed by diffusion tensor MR imaging (DTI) correlated with specific cognitive and motor impairments in survivors of pediatric posterior fossa tumors.
Recent Advances in 19Fluorine Magnetic Resonance Imaging with Perfluorocarbon Emulsions

The research roots of 19fluorine (19F) magnetic resonance imaging (MRI) date back over 35 years. Over that time span, 1H imaging flourished and was adopted worldwide with an endless array of applications and imaging approaches, making magnetic resonance an indispensable pillar of biomedical diagnostic imaging. For many years during this timeframe, 19F imaging research continued at a slow pace as the various attributes of the technique were explored. However, over the last decade and particularly the last several years, the pace and clinical relevance of 19F imaging has exploded. In part, this is due to advances in MRI instrumentation, 19F/1H coil designs, and ultrafast pulse sequence development for both preclinical and clinical scanners. These achievements, coupled with interest in the molecular imaging of anatomy and physiology, and combined with a cadre of innovative agents, have brought the concept of 19F into early clinical evaluation. In this review, we attempt to provide a slice of this rich history of research and development, with a particular focus on liquid perfluorocarbon compound-based agents.
