Study Design Cross-sectional cohort study. Background Symptoms of depression, panic disorder (PD), and posttraumatic stress disorder (PTSD) have been associated with musculoskeletal complaints and could represent barriers to recovery in injured workers. Objectives To determine the prevalence of symptoms of depression, PD, and PTSD utilizing the Patient Health Questionnaire (PHQ) in a cohort of patients presenting to an upper extremity injured-worker clinic; secondarily, to identify any relationships between patients screening positive and patient-reported outcome measures. Methods In 2010, 418 patients completed the PHQ during their initial evaluation. Patients with PHQ scores exceeding threshold values for symptoms of depression, PD, or PTSD were compared based on patient-reported outcome scores, including the Disabilities of the Arm, Shoulder and Hand questionnaire (DASH) and Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36). The prevalence of symptoms, and their relationship with presenting complaints and patient-reported outcomes, were calculated. Results Thirty-one percent of patients scored above thresholds for symptoms of at least 1 mental health disorder. Of those who screened positive, 67% screened positive for depression, 44% for PTSD, and 50% for PD, with 43% of patients positive for multiple symptoms. Patients experiencing neck pain had significantly higher screening rates of depressive symptoms (62.5% versus 20.1%, P = .004) and PD (37.5% versus 12.9%, P = .044) compared with other presenting complaints. Similarly, patients with chronic pain had higher rates of depression (54.5% versus 20.1%, P = .006), PD (63.6% versus 12%, P<.001), and PTSD (36.4% versus 14.8%, P = .05) compared with other presenting complaints. Patients endorsing depressive symptoms had significantly lower SF-36 mental component summary scores (26.3 ± 10.7 versus 37.6 ± 9.9, P<.001) and higher shortened-version DASH (72.3 ± 16.7 versus 61.5 ± 11.1, P = .003) and DASH work scores (86.5 ± 19.2 versus 82.1 ± 20.1, P = .007) compared to patients endorsing other items on the PHQ. Conclusion In this prospective cohort study of injured workers, we identified a relatively high prevalence of symptoms of psychological disorders utilizing the PHQ, with one third of injured workers screening positive for symptoms of depression, PD, or PTSD. Further longitudinal follow-up is necessary to determine the impact on treatment outcomes. Level of Evidence Symptom prevalence, level 1b. J Orthop Sports Phys Ther 2016;46(7):590–595.

Published: May 2016

Study Design Cohort study, repeated measures. Background Although hamstring strength measurements are used for assessing prognosis and monitoring recovery after hamstring injury, their actual clinical relevance has not been established. Handheld dynamometry (HHD) is a commonly used method of measuring muscle strength. The reliability of HHD has not been determined in athletes with acute hamstring injuries. Objectives To determine the intertester reliability and the prognostic value of hamstring HHD strength measurement in acute hamstring injuries. Methods We measured knee flexion strength with HHD in 75 athletes at 2 visits, at baseline (within 5 days of hamstring injury) and follow-up (5 to 7 days after the baseline measurement). We assessed isometric hamstring strength in 15° and 90° of knee flexion. Reliability analysis testing was performed by 2 testers independently at the follow-up visit. We recorded the time needed to return to play (RTP) up to 6 months following baseline. Results The intraclass correlation coefficients of the strength measurements in injured hamstrings were between 0.75 and 0.83. There was a statistically significant but weak correlation between the time to RTP and the strength deficit at 15° of knee flexion measured at baseline (Spearman r = 0.25, P = .045) and at the follow-up visit (Spearman r = 0.26, P = .034). Up to 7% of the variance in time to RTP is explained by this strength deficit. None of the other strength variables were significantly correlated with time to RTP. Conclusion Hamstring strength can be reliably measured with HHD in athletes with acute hamstring injuries. The prognostic value of strength measurements is limited, as there is only a weak association between the time to RTP and hamstring strength deficit after acute injury.

Study Design Randomized clinical trial. Background Motor control exercises are believed to improve coordination of the trunk muscles. It is unclear whether increases in trunk muscle thickness can be facilitated by approaches such as the McKenzie method. Furthermore, it is unclear which approach may have superior clinical outcomes. Objectives The primary aim was to compare the effects of the McKenzie method and motor control exercises on trunk muscle recruitment in people with chronic low back pain classified with a directional preference. The secondary aim was to conduct a between-group comparison of outcomes for pain, function, and global perceived effect. Methods Seventy people with chronic low back pain who demonstrated a directional preference using the McKenzie assessment were randomized to receive 12 treatments over 8 weeks with the McKenzie method or with motor control approaches. All outcomes were collected at baseline and at 8-week follow-up by blinded assessors. Results No significant between-group difference was found for trunk muscle thickness of the transversus abdominis (−5.8%; 95% confidence interval [CI]: −15.2%, 3.7%), obliquus internus (−0.7%; 95% CI: −6.6%, 5.2%), and obliquus externus (1.2%; 95% CI: −4.3%, 6.8%). Perceived recovery was slightly superior in the McKenzie group (−0.8; 95% CI: −1.5, −0.1) on a −5 to +5 scale. No significant between-group differences were found for pain or function (P = .99 and P = .26, respectively). Conclusion We found no significant effect of treatment group for trunk muscle thickness. Participants reported a slightly greater sense of perceived recovery with the McKenzie method than with the motor control approach. Level of Evidence Therapy, level 1b-.

Study Design Level 4, controlled laboratory study. Background Little is known regarding how the potential differences between treadmill and overground running may affect patellofemoral joint and Achilles tendon loading characteristics. Objectives To compare measures of loading of the patellofemoral joint and Achilles tendon across treadmill and overground running in healthy, uninjured runners. Methods Eighteen healthy runners ran at their self-selected speed on an instrumented treadmill and overground, while 3-D running mechanics were sampled. A musculoskeletal model derived peak load, rate of loading, and estimated cumulative load per 1 km of continuous running for the patellofemoral joint and Achilles tendon for each condition. Data were analyzed via paired t tests and Pearson correlations to detect differences and assess relationships, respectively, between the 2 running mediums. Results No differences (P>.05) were found between treadmill and overground running for peak load, rate of loading, or estimated cumulative patellofemoral joint stress per 1 km of continuous running. However, treadmill running resulted in 12.5% greater peak Achilles tendon force (P<.001), 15.6% greater loading rate of Achilles tendon force (P<.001), and 14.2% greater estimated cumulative Achilles tendon force per 1 km of continuous running (P<.001) compared with overground running. There were strong (r>0.70) and moderate agreements (r>0.50) for most patellofemoral joint and Achilles measures, respectively, between treadmill and overground running. Conclusion No differences were observed in loading characteristics to the patellofemoral joint between running mediums; however, treadmill running resulted in greater Achilles tendon loading compared with overground running. Future investigations should examine whether sudden bouts of treadmill running may increase the risk of mechanical overload of the Achilles tendon in runners who habitually train overground.

HOW ENVIRONMENT AFFECTS GALAXY METALLICITY THROUGH STRIPPING AND FORMATION HISTORY: LESSONS FROM THE ILLUSTRIS SIMULATION
Authors: Genel Shy 
Published: May 2016

ABSTRACT
Recent studies have found higher galaxy metallicities in richer environments. It is not yet clear, however, whether metallicity-environment dependencies are merely an indirect consequence of environmentally dependent formation histories, or of environmentally related processes directly affecting metallicity. Here, we present a first detailed study of metallicity-environment correlations in a cosmological hydrodynamical simulation, in particular, we focus on the Illustris simulation. Illustris galaxies display similar relations to those observed. Utilizing our knowledge of simulated formation histories, and leveraging the large simulation volume, we construct galaxy samples of satellites and centrals with matching formation histories. This allows us to find that

of the metallicity-environment correlation is due to different formation histories in different environments. This is a combined effect of satellites (in particular, in denser environments) having on average lower z = 0 star formation rates (SFRs), and of their older stellar ages, even at a given z = 0 SFR. Most of the difference,

, however, is caused by the higher concentration of star-forming disks of satellite galaxies, as this biases their SFR-weighted metallicities toward their inner, more metal-rich parts. With a newly defined quantity, the “radially averaged” metallicity, which captures the metallicity profile but is independent of the SFR profile, the metallicities of satellites and centrals become environmentally independent once they are matched in formation history. We find that circumgalactic metallicity (defined as rapidly inflowing gas around the virial radius), while sensitive to environment, has no measurable effect on the metallicity of the star-forming gas inside the galaxies.
SUPPLEMENT TO “TORSIONAL OSCILLATIONS OF A MAGNETAR WITH A TANGLED MAGNETIC FIELD” (2016, ApJL, 823, L1)*

ABSTRACT
We introduce a mean-field formalism with which to study the oscillations of a neutron star or other stellar object with a dipolar magnetic field plus a topologically distinct isotropic magnetic tangle that stabilizes the field configuration. In terms of the ratio of the energy density of the tangled field to that in the dipolar component b

The use of technology is changing the way things are done, including the work in universities where the teaching and learning process are changing, and it is required to know the effect of technology on student achievement. In this research work, we present the influence of Internet use on academic success of students from five universities in Ecuador. A random sample of 4,697 people was got up and categorized in two groups: the use of Internet in academic activities and entertainment, using factor analysis and cluster analysis; the resulting categories were used as independent variables in multinomial logistic regression model which are seeking to determine if the use of Internet has impacted on academic success. The results show that people who perform interactive activities with peers and teachers or use in a balanced way the different internet tools tend to have more academic success than those who only seeks information. Regarding to the use of Internet in entertainment, a positive impact was found on academic achievement. Students who download audio, video and software, and students who use all the entertainment possibilities show less likely to fail than who using minimally Internet. In terms of gender, it has different effects for entertainment and academic purposes.
El uso de la tecnología provoca cambios sociales. Esto incluye el trabajo en el ámbito universitario en donde está cambiando tanto la forma de ejercer la docencia como la forma de aprender y se requiere conocer el efecto del uso de la tecnología sobre el rendimiento del alumnado. En este trabajo se investigó la incidencia del uso de Internet sobre el éxito académico del alumnado de cinco universidades de Ecuador. Se levantó una muestra aleatoria de 4.697 personas y se las categorizó en perfiles de uso de Internet para actividades académicas y para entretenimiento, utilizando análisis factorial y análisis clúster. Las categorías resultantes se utilizaron como variables independientes en modelos de regresión logística multinomial que buscaban determinar si el uso de Internet tenía incidencia sobre el éxito académico. Los resultados muestran que quienes realizan actividades interactivas con pares y profesores o quienes utilizan de forma balanceada las distintas herramientas de Internet tienden a un mayor éxito académico que aquellos que solo buscan información. En lo referente al entretenimiento, se encontró una incidencia positiva del uso de Internet sobre el éxito académico. Los estudiantes que realizan descargas de contenido de audio, video y software, y quienes utilizan todas las posibilidades de entretenimiento, presentan menor tendencia a suspender que los estudiantes que utilizan mínimamente Internet. En cuanto al género se presentan diferencias en los usos académicos y de entretenimiento.

Taking notes is a common strategy among higher education students, and has been found to affect their academic performance. Nowadays, however, the use of computers is replacing the traditional pencil-and-paper methodology. The present study aims to identify the advantages and disadvantages associated with the use of computer (typing) and pencil-and-paper (handwriting) for taking notes by college students. A total of 251 social and health science students participated in the study. Two experimental conditions were chosen: taking notes by hand (n=211), and taking notes by computer (n=40). Those that used computer-written notes performed better on tasks based on reproducing the alphabet, writing sentences, and recognizing words (p<.05). However, those using handwritten notes performed better on free recall tasks (p<.05). Differences between the two conditions were statistically significant rejecting the hypothesis of equality between groups (X2=60.98; p<.0001). In addition, the discriminant analysis confirmed that 77.3% of students were correctly classified by the experimental conditions. Although the computer allowed for greater velocity when taking notes, handwriting enhanced students’ grades when performing memory tasks.
La toma de apuntes es una estrategia generalizada del alumnado de Educación Superior y se ha constatado su influencia en el rendimiento académico. El uso del ordenador está desplazando al método tradicional de lápiz y papel. El presente estudio pretende arrojar luz sobre las ventajas y los inconvenientes derivados del uso de uno u otro método en la toma de apuntes en las aulas universitarias. Un total de 251 estudiantes universitarios de ciencias sociales y ciencias de la salud participaron en el estudio. Se plantearon dos condiciones experimentales: toma de notas de forma manual (n=211) y de manera electrónica (n=40). Se hallaron diferencias a favor del grupo que usó el ordenador en las tareas basadas en completar el abecedario, escribir frases y reconocer palabras anotadas previamente (p<.05). Sin embargo, en la tarea de recuerdo libre los resultados reflejaron un mejor desempeño del grupo que tomó notas manualmente (p<.05). Se rechazó la hipótesis de igualdad entre los grupos (X2=60,98; p<.0001). Además, el análisis discriminante confirmó que el 77,3% de los alumnos fueron clasificados correctamente según su condición experimental. El uso del ordenador resultó muy útil cuando se trataba de anotar datos con rapidez; sin embargo, en las tareas de recuerdo los alumnos de escritura manual obtuvieron mejores puntuaciones que los de escritura electrónica.
Entre déviance et défense : la consommation de cannabis chez les ouvriers de l’assistance aéroportuaire
Authors: Brugière Fabien 
Published: May 2016

Cet article se propose d’étudier la consommation de cannabis sur le lieu et lors du temps de travail chez les ouvriers de l’assistance en piste aéroportuaire. Pour ce faire, il se fonde sur une enquête ethnographique par observation participante réalisée de 2010 à 2012 sur un aéroport d’Île-de-France. Le contexte de précarisation de l’emploi et d’intensification du travail met les salariés de l’assistance en piste sous-traitée sous pression et accroît le mal-être au travail. On observe par ailleurs la présence (minoritaire) d’une consommation de cannabis, en dépit des règles et des contrôles de sécurité, dans les « coulisses » et les « à-côtés » du travail. On peut rendre compte de la poursuite d’une telle pratique malgré les risques encourus en l’analysant comme le support d’une stratégie de défense visant à mettre à distance la souffrance au travail.
Création de dispositif pour une psychanalyse impliquée Ateliers d’artistes à l’hôpital avec des adolescents
Authors: Gassmann Xavier , Masson Céline 
Published: May 2016

À partir du dispositif proposé à l’Esquisse, hôpital de jour de Pontoise pour adolescents, où des artistes rencontrent les adolescents dans le cadre d’ateliers, l’article interroge un nouveau type de dispositif référé au champ psychanalytique et donc fondé sur la prise en compte de la dynamique transférentielle. Ni art-thérapie, ni médiations thérapeutiques, ce dispositif est original et permet que la psychanalyse, malgré les résistances rencontrées dans les lieux de soin, continue autrement. En cela, l’article s’inscrit dans le quatrième axe proposé par la thématique de la revue, à savoir « comment la psychanalyse se réinvente-t-elle ? Qu’en est-il du cadre analytique et de la psychanalyse hors les murs ? ».
Figures de la vengeance dans la postmodernité : le héros et le barbare
Authors: Delhaye Pascaline 
Published: May 2016

Arme dangereuse qui peut attiser la haine, la vengeance peut également être envisagée comme moyen de réclamer justice et de contrôler socialement la violence, à condition d’être prise dans une organisation et une dynamique culturellement définies. Son traitement social amenant à y renoncer reflète alors le système de valeurs de chaque société et révèle ainsi les structures symboliques en jeu. Dans la postmodernité de nos sociétés occidentales, quelle contenance permet ce renoncement ? Le présent article, issu d’une thèse de doctorat en psychologie, se propose de traiter cette question et révèle deux figures du vengeur, à savoir le héros et le barbare, qui, l’un et l’autre, parlent du rapport à l’altérité et à la culture.

Résumé En nous appuyant sur une trentaine d'entretiens menés auprès des salariés d'une grande entreprise du CAC 40, notre intention est de réfléchir sur les formes de socialisation professionnelle qu'induit un événement sportif interne de grande ampleur. Le fait de participer à l'une des éditions du Raid organisé par leur employeur renforce-t-il l'appropriation des valeurs de l'entreprise par les salariés ? Ces derniers portent-ils un regard différent sur leur entreprise et sa hiérarchie ? La socialisation particulière vécue durant les épreuves sportives conduit-elle les participants à modifier les relations professionnelles avec leurs collègues de travail ? Le sport peut-il être considéré comme un outil efficace de cohésion interne ?
L’émergence d’une enclave organisationnelle non gestionnaire. Le travail de l’imaginaire sportif au sein des espaces de compétition d’un championnat du monde
Authors: Philippe Xavier 
Published: May 2016

Résumé Le sport est aujourd'hui perçu comme une activité économique à part entière. Ainsi, de manière croissante, l'univers sportif adopte des pratiques gestionnaires importées du secteur marchand. Que devient alors l'imaginaire sportif ? C'est la question posée dans cet article. L'analyse sociologique conduite ici s'inspire des travaux de Castoriadis (1975) sur l'imaginaire et mobilise la grille d'analyse de l'institution définie par Lallement (2007, 2008). Notre étude porte sur les Jeux équestres mondiaux 2014 dont nous avons observé la préparation et le déroulement pendant plus de dix-huit mois. Ici, les pratiques gestionnaires instituées par les organisateurs et basées sur la mise en place de procédures et le respect du budget se confrontent à un imaginaire sportif, porté par certains acteurs, fondé sur la performance et la mise en valeur des athlètes, et conduisant à l'émergence d'une enclave organisationnelle spécifique.
