Visual Perception And Its Effect On Reaction Time And Time-Movement Anticipation In Elite Female Basketball Players
Authors: Mańkowska Maja , Poliszczuk Tatiana , Poliszczuk Dmytro , Johne Monika 
Published: June 2015

Abstract

Introduction
. The efficient collection and analysis of information from both the central and the peripheral field of vision may affect human coordination motor abilities. An analysis of the literature on the subject suggests that coordination motor abilities interact with one another, and it is only their combined effect that allows athletes to achieve technical mastery. The main aim of the study was to assess specific coordination motor abilities and to determine how visual perception and reaction time correlate with time-movement anticipation in elite female basketball players.

Material and methods
. The study participants comprised 17 female basketball players from the Polish National Team aged 18.1 ± 0.8 years. The study involved three ability tests from the Vienna Test System: the Reaction Test (RT, S1), the Peripheral Perception test (PP), and the Time/Movement Anticipation test (ZBA, S2).

Results
. The analysis of the results obtained proves that the best-developed ability in participants is reaction time, while the other abilities show average development. Study participants were able to develop their response abilities to such high levels by means of practice. A correlation coefficient was found between motor time and tracking deviation (r=0.56), and between time anticipation and the number of correct responses to stimuli appearing in the left (r=0.92) and right (r=0.88) field of vision. Athletes who achieved better results in time anticipation omitted fewer visual stimuli (r=0.7) in the peripheral field of vision. Statistically significant correlations were observed between movement anticipation and reaction time to stimuli in the central field of vision (r=0.58).

Conclusions
. Perception abilities have a significant effect on time anticipation. The range of one's field of vision does not determine the reaction time to a visual stimulus. Perception efficiency and divided attention, in conjunction with time and movement anticipation, create a complex of specific psychomotor abilities that is indispensable for achieving success in team sports.

Abstract

Introduction
. Martial arts and combat sports are practical sports that are being practised by an increasing number of women. The aim of this study was to examine the relationship between the ability of female judo, taekwondo and karate competitors to fall safely and their susceptibility to injuries during falls.

Material and methods
. A total of 120 persons participated in the research. The study group consisted of 45 female judo, taekwondo (WTF) and karate Shotokan competitors; in the control group there were 75 persons who did not practise sport professionally. The research tools included the Test of Susceptibility to Injury during Falls (TSIDF) developed by Kalina and a questionnaire designed by the authors.

Results
. The female martial arts competitors had considerably lower TSIDF results (p<0.001), which means that they made fewer errors when performing motor tasks. The mean result of the TSIDF was 2.48 for the study group and 6.08 for the control one. Significant differences (p<0.001) were found between the groups for all types of errors and all of the motor tasks.

Conclusions
. Women practising combat sports and martial arts made significantly fewer errors in the Test of Susceptibility to Injuries During Falls, which can be seen as evidence for the practical usefulness of the training they are undergoing.
Recurrence quantification analysis of denoised index returns via alpha-stable modeling of wavelet coefficients: detecting switching volatility regimes
Authors: Tzagkarakis George , Dionysopoulos Thomas , Achim Alin 
Published: June 2015

AbstractIn this paper we propose an enhancement of recurrence quantification analysis (RQA) performance in extracting the underlying non-linear dynamics of market index returns, under the assumption of data corrupted by additive white Gaussian noise. More specifically, first we show that the statistical distribution of wavelet decompositions of distinct index returns is best fitted using members of the alpha-stable distributions family. Then, an efficient maximum a posteriori (MAP) estimator is applied on pairs of wavelet coefficients at adjacent levels to suppress the noise effect, prior to performing RQA. Quantitative and qualitative results on 22 future indices indicate an improved interpretation capability of RQA when applied on denoised data using our proposed approach, as opposed to previous methods based solely on a Gaussian assumption for the underlying statistics, in terms of extracting the underlying dynamical structure of index returns generating processes. Furthermore, our results reveal an increased accuracy of the proposed method in detecting switching volatility regimes, which is important for estimating the risk associated with a financial instrument.
Publicaciones académicas, indexaciones y resistencia

<p>Este artículo analiza el destino paradójico de las publicaciones científicas en Colombia. Por un lado, las publicaciones científicas son el resultado natural de la investigación, la conclusión de un silogismo que ninguna mente sana podría evitar. Por otro, buena parte de la comunidad colombiana de investigadores, en un esfuerzo por no dejar subir la barra de las exigencias se opone a los sistemas de medición más exigentes y abogan por sistemas más laxos. Exponer el sistema moral y sociológico de esta paradoja es el objeto del presente artículo. El artículo se ocupa de exponer el sistema de razones, justificaciones y resistencias docentes a las exigencias de la indexación, al tiempo que da una respuesta lógica<br />a lo absurdo de este intento.

Charles Darwin y la representación de las comunidades afro en su narrativa de viajes
Authors: Díaz Dorismel 
Published: June 2015

<p>¿Qué significa representar al afro en el relato de viajes del siglo xix? Esta es la pregunta esencial propuesta para explorar la temática. Para responder a tal interrogante, se hará un enfoque en el estudio de la narrativa de viajes planteada por Charles Darwin (1809-1882). El trabajo explora la manera como la comunidad negra es retratada, así como los mecanismos discursivos que el escritor emplea para narrarlas. Mediante este análisis, se pretende mostrar cómo el viajero narra y reconstruye a las comunidades afrodescendientes a través de unas estrategias de representación recurrentes mediatizadas por el imaginario europeo, en su afán de interpretarlas y describirlas en su comunidad de origen. Los dispositivos que usa para caracterizar la otredad revelan una ideología entretejida de inconsistencias, ambigüedades y contradicciones que parodian el discurso colonial. Dicho discurso será analizado desde el punto de vista de los lineamientos teóricos planteados por David Spurr en su libro <em>The Rhetoric of Empire: Colonial Discourse in Journalism, Travel Writing and Imperial Administration </em>y Mary Louise Pratt en <em>Imperial Eyes: Travel Writing and Transculturation. </em>A lo largo del trabajo, se tienen en cuenta los conceptos claves manejados por el aparato crítico, con el fin de clasificar los escenarios donde transcurren los encuentros culturales. Como quiera que este viajero ostenta el papel de autoridad intelectual, se presta particular atención a la conexión existente entre esas posiciones discursivas y el rol que estas cumplen en contribuir a pensar la cultura e identidad afro.</p>
A Transparent Window into Biology: A Primer on Caenorhabditis elegans
Authors: Corsi Ann K , Wightman Bruce , Chalfie Martin 
Published: June 2015

Abstract
A little over 50 years ago, Sydney Brenner had the foresight to develop the nematode (round worm) Caenorhabditis elegans as a genetic model for understanding questions of developmental biology and neurobiology. Over time, research on C. elegans has expanded to explore a wealth of diverse areas in modern biology including studies of the basic functions and interactions of eukaryotic cells, host–parasite interactions, and evolution. C. elegans has also become an important organism in which to study processes that go awry in human diseases. This primer introduces the organism and the many features that make it an outstanding experimental system, including its small size, rapid life cycle, transparency, and well-annotated genome. We survey the basic anatomical features, common technical approaches, and important discoveries in C. elegans research. Key to studying C. elegans has been the ability to address biological problems genetically, using both forward and reverse genetics, both at the level of the entire organism and at the level of the single, identified cell. These possibilities make C. elegans useful not only in research laboratories, but also in the classroom where it can be used to excite students who actually can see what is happening inside live cells and tissues.

Authors: Schlesinger Naomi , Radvanski Diane C , Young Tina C , McCoy Jonathan V , Eisenstein Robert , Moore Dirk F 
Published: June 2015

Background :
Acute gout attacks account for a substantial number of visits to the emergency department (ED). Our aim was to evaluate acute gout diagnosis and treatment at a University Hospital ED.

Methods :
Our study was a retrospective chart review of consecutive patients with a diagnosis of acute gout seen in the ED 1/01/2004 - 12/31/2010. We documented: demographics, clinical characteristics, medications given, diagnostic tests, consultations and whether patients were hospitalized. Descriptive and summary statistics were performed on all variables.

Results :
We found 541 unique ED visit records of patients whose discharge diagnosis was acute gout over a 7 year period. 0.13% of ED visits were due to acute gout. The mean patient age was 54; 79% were men. For 118 (22%) this was their first attack. Attack duration was ≤ 3 days in 75%. Lower extremity joints were most commonly affected. Arthrocentesis was performed in 42 (8%) of acute gout ED visits.
During 355 (66%) of ED visits, medications were given in the ED and/or prescribed. An anti-inflammatory drug was given during the ED visit during 239 (44%) visits. Medications given during the ED visit included: NSAIDs: 198 (56%): opiates 190 (54%); colchicine 32 (9%) and prednisone 32 (9%). During 154 (28%) visits an anti-inflammatory drug was prescribed. Thirty two (6%) were given no medications during the ED visit nor did they receive a prescription. Acute gout rarely (5%) led to hospitalizations.

Conclusion :
The diagnosis of acute gout in the ED is commonly clinical and not crystal proven. Anti-inflammatory drugs are the mainstay of treatment in acute gout; yet, during more than 50% of ED visits, anti-inflammatory drugs were not given during the visit. Thus, improvement in the diagnosis and treatment of acute gout in the ED may be required.

OBJECTIVE
Ingestion of probiotics can modify gut microbiota and alter insulin resistance and diabetes development in rodents. We hypothesized that daily intake of Lactobacillus reuteri increases insulin sensitivity by changing cytokine release and insulin secretion via modulation of the release of glucagon-like peptides (GLP)-1 and -2.

RESEARCH DESIGN AND METHODS
A prospective, double-blind, randomized trial was performed in 21 glucose-tolerant humans (11 lean: age 49 ± 7 years, BMI 23.6 ± 1.7 kg/m2; 10 obese: age 51 ± 7 years, BMI 35.5 ± 4.9 kg/m2). Participants ingested 1010 b.i.d. L. reuteri SD5865 or placebo over 4 weeks. Oral glucose tolerance and isoglycemic glucose infusion tests were used to assess incretin effect and GLP-1 and GLP-2 secretion, and euglycemic-hyperinsulinemic clamps with [6,6-2H2]glucose were used to measure peripheral insulin sensitivity and endogenous glucose production. Muscle and hepatic lipid contents were assessed by 1H-magnetic resonance spectroscopy, and immune status, cytokines, and endotoxin were measured with specific assays.

RESULTS
In glucose-tolerant volunteers, daily administration of L. reuteri SD5865 increased glucose-stimulated GLP-1 and GLP-2 release by 76% (P &lt; 0.01) and 43% (P &lt; 0.01), respectively, compared with placebo, along with 49% higher insulin (P &lt; 0.05) and 55% higher C-peptide secretion (P &lt; 0.05). However, the intervention did not alter peripheral and hepatic insulin sensitivity, body mass, ectopic fat content, or circulating cytokines.

CONCLUSIONS
Enrichment of gut microbiota with L. reuteri increases insulin secretion, possibly due to augmented incretin release, but does not directly affect insulin sensitivity or body fat distribution. This suggests that oral ingestion of one specific strain may serve as a novel therapeutic approach to improve glucose-dependent insulin release.

Published: June 2015

OBJECTIVE
Common circadian-related gene variants associate with increased risk for metabolic alterations including type 2 diabetes. However, little is known about whether diet and sleep could modify associations between circadian-related variants (CLOCK-rs1801260, CRY2-rs11605924, MTNR1B-rs1387153, MTNR1B-rs10830963, NR1D1-rs2314339) and cardiometabolic traits (fasting glucose [FG], HOMA-insulin resistance, BMI, waist circumference, and HDL-cholesterol) to facilitate personalized recommendations.

RESEARCH DESIGN AND METHODS
We conducted inverse-variance weighted, fixed-effect meta-analyses of results of adjusted associations and interactions between dietary intake/sleep duration and selected variants on cardiometabolic traits from 15 cohort studies including up to 28,190 participants of European descent from the Cohorts for Heart and Aging Research in Genomic Epidemiology (CHARGE) Consortium.

RESULTS
We observed significant associations between relative macronutrient intakes and glycemic traits and short sleep duration (&lt;7 h) and higher FG and replicated known MTNR1B associations with glycemic traits. No interactions were evident after accounting for multiple comparisons. However, we observed nominally significant interactions (all P &lt; 0.01) between carbohydrate intake and MTNR1B-rs1387153 for FG with a 0.003 mmol/L higher FG with each additional 1% carbohydrate intake in the presence of the T allele, between sleep duration and CRY2-rs11605924 for HDL-cholesterol with a 0.010 mmol/L higher HDL-cholesterol with each additional hour of sleep in the presence of the A allele, and between long sleep duration (≥9 h) and MTNR1B-rs1387153 for BMI with a 0.60 kg/m2 higher BMI with long sleep duration in the presence of the T allele relative to normal sleep duration (≥7 to &lt;9 h).

CONCLUSIONS
Our results suggest that lower carbohydrate intake and normal sleep duration may ameliorate cardiometabolic abnormalities conferred by common circadian-related genetic variants. Until further mechanistic examination of the nominally significant interactions is conducted, recommendations applicable to the general population regarding diet—specifically higher carbohydrate and lower fat composition—and normal sleep duration should continue to be emphasized among individuals with the investigated circadian-related gene variants.
End-to-end ureteral anastomosis and double-pigtail ureteral stent placement for treatment of iatrogenic ureteral trauma in two dogs
Authors: Wormser Chloe , Clarke Dana L. , Aronson Lillian R. 
Published: June 2015

Abstract
Case Description—A 6-month-old spayed female Soft-Coated Wheaten Terrier and 8-month-old spayed female Shih Tzu were referred because of complications related to inadvertent ureteral ligation and transection during recent ovariohysterectomy.
Clinical Findings—The Soft-Coated Wheaten Terrier had a 2-day history of stranguria and polyuria that began after ovariohysterectomy. Initial examination findings were unremarkable with the exception of high rectal temperature. The Shih Tzu had a 10-day history of pyrexia, vomiting, diarrhea, and stranguria that began after ovariohysterectomy. On examination, the dog had signs of depression; clinicopathologic tests revealed hypoalbuminemia, neutrophilia, lymphocytosis, and monocytosis. Abdominal ultrasonography was performed for both dogs, revealing severe unilateral pyelectasia and hydroureter (proximal portion).
Treatment and Outcome—Both dogs underwent exploratory celiotomy; ureteral ligation and transection was confirmed. Ventral cystotomy was performed to allow retrograde placement of a double-pigtail ureteral stent into the affected ureter and renal pelvis. End-to-end ureteral anastomosis was performed over the stent with the aid of an operating microscope. Stent position was confirmed via fluoroscopy, and incisions were closed routinely. Dogs continued to have intermittent signs of stranguria until stent removal via cystoscopy 6 or 7 weeks after surgery. Ultrasonographic examination of the urogenital tract was performed 2 or 4 months after surgery, revealing resolution of pyelectasia and hydroureter.
Clinical Relevance—The surgical technique used provided a viable option for preserving renal function in dogs with focal, iatrogenic ureteral trauma. Use of a ureteral stent facilitated ureteral anastomosis and minimized postoperative complications.

Abstract
Case Description—A 4-year-old Arabian-cross mare was examined because of a 48-hour history of pyrexia, lethargy, and signs of abdominal discomfort.
Clinical Findings—On initial evaluation, the horse was in good body condition, but febrile, tachycardic, tachypneic, and icteric and had signs of colic. Findings on CBC and serum biochemical analysis indicated marked systemic inflammation and hepatocellular damage. Serial abdominal ultrasonographic examinations revealed progressive, localized hepatic parenchymal abnormalities in the left ventral aspect of the abdomen in proximity to the left liver lobes, and eventual identification of an irregularly marginated, hyperechoic walled region of heterogenous echogenicity consistent with an encapsulated hepatic abscess.
Treatment and Outcome—Medical treatment was initiated with administration of doxycycline and flunixin meglumine. After 7 days, the horse's clinical signs and hematologic values improved. After 14 days, the horse was discharged from the hospital and prescribed continuation of doxycycline treatment for 14 days. One week following hospital discharge, the horse was reevaluated for recurrent signs of colic and pyrexia. The horse was sedated, and the region overlying the caudal aspect of the seventh rib was desensitized with an inverted L nerve block by local infiltration with 2% lidocaine. While the horse was standing and sedated, drainage of an encapsulated intra-abdominal abscess was followed by rib resection and removal of a portion of necrotic left lateral liver lobe. The development of a pneumothorax following rib resection represented the only major surgical complication. Twelve months later, the horse was clinically normal and had returned to its previous level of performance.
Clinical Relevance—Rib resection in standing sedated horses, together with appropriate medical management, should be considered an option for removal of well-encapsulated cranially located intra-abdominal abscesses that are adherent to the ventrolateral aspect of the body wall in horses.
Autour du Jardin des Vestiges à Marseille (Bouches-du-Rhône) : fragments d’histoire médiévale et moderne
Authors: Scherrer Nadine 
Published: June 2015

Around the Jardin des Vestiges in Marseille (Bouches-du-Rhône) : fragments of the Middle Ages and Modern history.
This article shows the results of a diagnostic campaign in blinded wells carried on in Marseille. These surveys are located around the Jardin des Vestiges, a garden in which are maintained the vestiges of the antique port and of the way called of Italy opening to one of the doors in the antique city rampart. Thus they are outside the walls but nearby the surrounding walls, in an area that has been developing over the Middle Ages and during the modern period. The little information gathered is put in relation with what is known from the texts and older excavations made in the surrounding area. Since no excavation has been done up to now after this expertise campaign, it appeared appropriate to publish the results.
De la coopération intégrale à la réforme de l’entreprise : l’intéressement salarial au prisme du Familistère de Guise
Authors: Dos Santos Jessica 
Published: June 2015

La Société du Familistère de Guise est une entreprise démocratique fondée en 1880 par Jean-Baptiste Godin, industriel partisan d’un socialisme réformiste. Il y applique les principes coopératifs de la « participation », terme à comprendre comme un partage avec les ouvriers de la gestion de l’entreprise, de son capital et de ses bénéfices. Jusqu’en 1968, cette société conserve, malgré les épreuves, ce fonctionnement original et devient ainsi un modèle pour les défenseurs de la participation aux bénéfices. À travers leur histoire et leurs archives, on constate une forte évolution du sens pris par ce terme de « participation » : d’abord prônée par les partisans de la coopération, cette politique salariale est ensuite envisagée par une partie du patronat avant de finalement prendre une forme législative très éloignée des idéaux d’origine.
Le postfordisme comme mythe et idéologie de la sociologie économique. Du consommateur à la construction sociale du marché automobile
Authors: Jullien Bernard , Pardi Tommaso 
Published: June 2015

Ce papier déconstruit le modèle explicatif postfordiste de la crise des années 1970 en se focalisant sur la transformation de l’industrie automobile occidentale depuis le début des années 1980. Les auteurs montrent que le passage à une offre de plus en plus pléthorique de modèles renouvelés plus rapidement n’était pas tiré par la demande « postfordienne » d’un nouveau « consommateur roi », mais poussé par une évolution des stratégies des entreprises endogène à la conception du contrôle du secteur. Ils questionnent ainsi la tendance de la sociologie économique française à traiter exclusivement le marché comme un espace de transactions centré sur le consommateur.
