Published: September 2016

ABSTRACT
We have combined the published observations of high-mass X-ray binary (HMXB) pulsars in the Magellanic Clouds with a new processing of the complete archival data sets from the XMM-Newton and Chandra observatories in an attempt to trace the lowest propeller line below which accretion to polar caps is inhibited by the centrifugal force and the pulsations from the most weakly magnetized pulsars cease. Previously published data reveal that some of the faster-spinning pulsars with spin periods of P

diagram, characterized by a magnetic moment of μ = 3 × 1029 G cm3. This value implies the presence of surface magnetic fields of B ≥ 3 × 1011 G in the compact objects of this class. Only a few quiescent HMXBs are found below the propeller line: LXP4.40 and SXP4.78, for which XMM-Newton and Chandra null detections respectively placed firm upper limits on their X-ray fluxes in deep quiescence; and A0538-66, for which many sub-Eddington detections have never measured any pulsations. On the other hand, the data from the XMM-Newton and Chandra archives show clearly that, during routine observation cycles, several sources have been detected below the propeller line in extremely faint, nonpulsating states that can be understood as the result of weak magnetospheric emission when accretion to the poles is centrifugally stalled or severely diminished. We also pay attention to the anomalous X-ray pulsar CXOU J010043.1-721134 that was reported in HMXB surveys. Its pulsations and locations near and above the propeller line indicate that this pulsar could be accreting from a fossil disk.

ABSTRACT
This is the second paper in a series on a new luminous z ∼ 5 quasar survey using optical and near-infrared colors. Here we present a new determination of the bright end of the quasar luminosity function (QLF) at z ∼ 5. Combining our 45 new quasars with previously known quasars that satisfy our selections, we construct the largest uniform luminous z ∼ 5 quasar sample to date, with 99 quasars in the range of 4.7 ≤ z < 5.4 and −29 < M
1450 ≤ −26.8, within the Sloan Digital Sky Survey (SDSS) footprint. We use a modified 1/V
a method including flux limit correction to derive a binned QLF, and we model the parametric QLF using maximum likelihood estimation. With the faint-end slope of the QLF fixed as α = −2.03 from previous deeper samples, the best fit of our QLF gives a flatter bright end slope β = −3.58 ± 0.24 and a fainter break magnitude

= −26.98 ± 0.23 than previous studies at similar redshift. Combined with previous work at lower and higher redshifts, our result is consistent with a luminosity evolution and density evolution model. Using the best-fit QLF, the contribution of quasars to the ionizing background at z ∼ 5 is found to be 18%–45% with a clumping factor C of 2–5. Our sample suggests an evolution of radio loud fraction with optical luminosity but no obvious evolution with redshift.
SPATIALLY OFFSET ACTIVE GALACTIC NUCLEI. I. SELECTION AND SPECTROSCOPIC PROPERTIES

Published: September 2016

ABSTRACT
We present a sample of 18 optically selected and X-ray-detected spatially offset active galactic nuclei (AGNs) from the Sloan Digital Sky Survey (SDSS). In nine systems, the X-ray active galactic nucleus (AGN) is spatially offset from the galactic stellar core that is located within the 3″ diameter SDSS spectroscopic fiber. In 11 systems, the X-ray AGN is spatially offset from a stellar core that is located outside the fiber, with an overlap of two. To build the sample, we cross-matched Type II AGNs selected from the SDSS galaxy catalog with archival Chandra imaging and employed our custom astrometric and registration procedure. The projected angular (physical) offsets span a range of 0.″6 (0.8 kpc) to 17.″4 (19.4 kpc), with a median value of 2.″7 (4.6 kpc). The offset nature of an AGN is an unambiguous signature of a galaxy merger, and these systems can be used to study the properties of AGNs in galaxy mergers without the biases introduced by morphological merger selection techniques. In this paper (Paper I), we use our sample to assess the kinematics of AGN photoionized gas in galaxy mergers. We find that spectroscopic offset AGN selection may be up to

% incomplete due to small projected velocity offsets. We also find that the magnitude of the velocity offsets are generally larger than expected if our spatial selection introduces a bias toward face-on orbits, suggesting the presence of complex kinematics in the emission line gas of AGNs in galaxy mergers.
Pour une approche socio-écosystémique de la dette écologique : une responsabilité civile spécifique en cas d’atteintes à l’environnement
Authors: Camproux Duffrène Marie-Pierre 
Published: September 2016

Les atteintes à l’environnement toujours plus nombreuses posent la question de leur réparation. Les juristes peuvent participer à y répondre en proposant des instruments juridiques susceptibles d’y contribuer. La responsabilité civile permet d’obliger les personnes ayant causé des dommages à autrui à réparer ceux-ci. Un même mécanisme juridique est mobilisable dans la perspective de faire cesser l’atteinte et réparer les dommages écologiques. Cependant, le fait que les atteintes portent non pas sur des personnes ou des biens (choses appropriées) mais sur des éléments d’un écosystème pose difficultés. Il oblige à réfléchir sur l’adaptabilité de ce mécanisme dans ce domaine et sa capacité à permettre un accès à la justice. En termes de fondements, doit-on prôner un droit individuel à l’environnement, un droit de l’environnement ou encore envisager une protection des intérêts collectifs liés l’environnement perçu alors en tant que socio-écosystème ? Au-delà, la responsabilité civile étant d’ores et déjà actionnée en cas d’atteintes à l’environnement, des spécificités nécessitent d’être étudiées : quel lien juridique existe-t-il entre la société et l’environnement naturel, ou entre les humains au regard de l’environnement ? Et surtout, devant le juge, qui peut agir et pour demander quoi ?

Objective:The aim of this study was to evaluate the magnetic resonance imaging (MRI) findings of caudal regression syndrome (CRS) and concomitant anomalies in pediatric patients.Materials and Methods:A hospital-based cross-sectional retrospective study was conducted. The study group comprised 21 pediatric patients presenting to the Departments of Radiodiagnosis and Pediatric Surgery in a tertiary care hospital from May 2011 to April 2016. All patients were initially evaluated clinically followed by MRI.Results:In our study, 21 pediatric patients were diagnosed with sacral agenesis/dysgenesis related to CRS. According to the Pang's classification, 2 (9.5%) patients were Type I, 5 (23.8%) patients were Type III, 7 (33.3%) patients were Type IV, and 7 (33.3%) patients were of Type V CRS. Clinically, 17 (81%) patients presented with urinary incontinence, 6 (28.6%) with fecal incontinence, 9 patients (42.9%) had poor gluteal musculatures and shallow intergluteal cleft, 7 (33.3%) patients had associated subcutaneous mass over spine, and 6 (28.6%) patients presented with distal leg muscle atrophy. MRI showed wedge-shaped conus termination in 5 (23.8%) patients and bulbous conus termination in 3 (14.3%) patients above the L1 vertebral level falling into Group 1 CRS while 7 (33.3%) patients had tethered cord and 6 (28.6%) patients had stretched conus falling into Group 2 CRS.Conclusion:MRI is the ideal modality for detailed evaluation of the status of the vertebra, spinal cord, intra- and extra-dural lesions and helps in early diagnosis, detailed preoperative MRI evaluation and assessing concomitant anomalies and guiding further management with early institution of treatment to maximize recovery.

Published: September 2016

Objectives:The aim is to provide students in the preclinical with ultrasound image interpretation skills. Research question: Are students in smaller groups with access to a combination of lectures and hands-on patient contact most likely to have better ultrasound image interpretation skills, than students in larger groups with only interactive didactic lectures?Methodology:First-year students at the preclinical Program of the College of Medicine, participated in two 2-h introductory interactive ultrasound sessions. The study comprised two cohorts: 2012/2013 students, who were offered large group teaching (LGT) sessions (control group), and 2013/2014 students, who received the intervention in small group learning problem-based learning (PBL) sessions (experimental group). The overall learning objectives were identical for both groups. The success of the module was evaluated using pre- and post-tests as well as students’ feedback.Results:The students in the experimental group showed significantly higher scores in interpretations of images than those in the control group. The experimental group showed achievement of learning outcomes along with higher levels of satisfaction with the module compared to the latter.Conclusion:Posttest knowledge of the basics of ultrasound improved significantly over the pretest in the experimental group. In addition, students’ overall satisfaction of the ultrasound module was shown to be higher for the PBL compared to the LGT groups. Small groups in an interactive and PBL setting along with opportunities for hands-on practice and simultaneous visualization of findings on a high definition screen should enhance preclinical student learning of the basics of ultrasound. Despite the potential of ultrasound as a clinical, teaching and learning tool for students in the preclinical years, standardized recommendations have yet to be created regarding its integration into the curricula within academic institutions and clinical medicine. The interactive and PBL is here to stay at the college of medicine. Further research would be carried out to see if this trend persists in the upcoming vertical system-based curriculum of the college of medicine.

Children With Celiac Disease: Health-Related Quality of Life and Leisure Participation
Authors: Meyer Sonya , Rosenblum Sara 
Published: September 2016

AbstractOBJECTIVE. We compared health-related quality-of-life (HRQOL) perceptions of children with celiac disease (CD) with those of their parents to determine whether their leisure participation differs from that of children without CD and whether relationships exist between leisure participation and HRQOL.METHOD. Children with CD and their parents completed a disease-specific HRQOL self-report questionnaire, the Celiac Disease DUX. These children and matched controls without CD completed the Children’s Leisure Assessment Scale (CLASS).RESULTS. Parents perceived HRQOL significantly more negatively than did children. No significant group differences were found in leisure participation. However, specific CLASS food-related activities and HRQOL significantly correlated.CONCLUSION. Hearing the child’s voice in addition to the parents’ is important in determining the HRQOL of children with a chronic condition. Findings contribute to understanding of CD in the context of participation and well-being and can lead to development of occupational performance–based assessments and interventions for children with CD.
Coming Home to Family: Now Is the Time!
Authors: Stoffel Virginia (Ginny) 
Published: September 2016

Abstract
Family is a metaphor for the connectedness that occupational therapy practitioners and students feel for one another, for the American Occupational Therapy Association (AOTA), and toward those served. Exploring values and cultural practices that emanate from family experiences affects how we practice occupational therapy and engage with families; how we serve and lead; and how, as the profession approaches its 100th anniversary in the United States, we strengthen AOTA by welcoming all 213,000 practitioners and students who could become active, engaged members. The heartfelt connections experienced across our worldwide occupational therapy communities, giving support and nurturance to those who show promise, breaking down barriers and creating community as extended family, creating a sense of home and belonging, encouraging participation, and building excellence, strengthen the AOTA family. AOTA Vision 2025 serves as a means to facilitate the profession's future, where health, well-being, and quality of life are the outcomes of effective occupational therapy.

Authors: Alkhatnai Mubarak 
Published: September 2016

<p>This paper aims to investigate the writing processes of bilingual Saudi writers by means of think-aloud protocols. Think-aloud or talk-aloud protocols involve having participants verbally describe their activities while performing a given task. My goal was to understand the writing habits of Saudi EFL/ESL learners and what native Arabic speakers experience when writing in English by examining how they write compositions in English. My basic question for this investigation was “How do EFL/ESL Saudi learners write in English?” The goal of this study was to identify useful information for teaching EsL composition to Arabic-speaking learners in general and Saudi learners in particular. </p>
Direct Perception Expression in Japanese and Chinese
Authors: Li Wenchao 
Published: September 2016

<p>This paper tackles the adjective distribution in two different languages, Altaic language: Japanese and Sino-Tibetan language: Chinese. The findings bring us to the point that Japanese direct perception expression tolerates both open-scale and closed-scale adjectives. Chinese direct perception expression only licenses ‘totally open-scale adjectives’ and rule out ‘upper closed-scale adjectives’, ‘totally closed-scale adjectives’, ‘lower closed-scale adjectives’. The failure of Chinese closed-scale AP in direct perception expression lies in that the perception verb <em>jian </em>‘to see’ is subjective. Open-scale adjectival perception verb complements in German and Chinese may invite temporary predications only by the addition of syntactic context, thus enabling the German/Chinese perception verb <em>sehen</em>, <em>kanjian /</em><em>jian</em> to make a conceptualisation of the perceived event, offering an ‘evaluation’ or ‘interpretation’. </p>

Purpose To determine the relationship between preoperative and postoperative characteristics and visual outcomes after successful surgery for unclosed macular hole (MH). Methods The medical charts of 166 eyes of 161 patients who underwent vitrectomy for a MH were reviewed. The MH was not closed in 9 eyes of 9 patients after the initial surgery. The second vitrectomy with additional internal limiting membrane (ILM) peeling and gas tamponade was performed. The preoperative and postoperative best-corrected visual acuity (BCVA), optical coherence tomographic images, MH size, duration of MH before the first operation, and area of ILM peeling were studied. Results The MH was closed in all eyes after the second surgery. The BCVA significantly improved from 0.77 to 0.25 logMAR units (20/118 to 20/36, p = 0.002). The postoperative subfoveal ellipsoid zone (EZ) was distinct and continuous in 3 eyes with good visual recovery. The final BCVA was not significantly correlated with the baseline characteristics and area of ILM peeling but was correlated with the postoperative status of the EZ. Conclusions All MHs were closed and the mean postoperative visual acuity was significantly improved. The reason for poor visual recovery was the reduced microstructural recovery after the second surgery.

Aim The aim of this study is to investigate whether TNF-α or LT-α polymorphisms are associated with the risk of leukemia. Methods A meta-analysis was performed to examine the association between the TNF-α −308 G>A and LT-α +252 A>G polymorphisms and the incidence of leukemia. We also performed subgroup analyses based on the classification of leukemias. Odds ratios (ORs) with 95% confidence intervals (CIs) were used to evaluate the association. Results A total of 19 publications comprising 1,509 cases and 4,075 controls were selected in the study. An association between the risk of leukemia and the LT-α +252 AA genotype was found (GG + AG vs. AA, OR = 0.485, 95% CI 0.368-0.639, p = 0.000). After multivariable analysis TNF-α polymorphism showed no consistent association with leukemia. Conclusions This meta-analysis suggests that the LT-α +252 AA polymorphism is associated with the risk of leukemia.
Mitomycin C: New Strategies to Improve Efficacy of a Well-Known Therapy

Published: September 2016

Mitomycin C (MMC) as an intravesical chemotherapeutic agent is a well-known option for treatment of nonmuscle invasive bladder cancer (NMIBC) recurrence; it is probably the most commonly used agent given its low rate of side effects and its efficacy. Both the American Urologic Association (AUA) and European Association of Urology (EAU) consider MMC as a standard treatment for immediate single-dose postoperative treatment and for adjuvant therapy in low and intermediate-risk NMIBC. Despite the popularity of this agent in the treatment of NMIBCs, many questions regarding the optimal approach to MMC therapy remain unanswered and the schedule widely used is empirical. Nevertheless, even when the current optimal approaches to MMC administration are used, a large proportion of NMIBCs recur. This apparent treatment resistance might be overcome by an optimization of standard MMC therapy or with a combination of MMC with other agents that have different mechanisms of action. Strategies to enhance passive delivery of MMC have been well studied and multiple measures are recommended for implementation of use in routine clinical practice. A modified scheme of instillation seems to be an easy and inexpensive alternative to increase efficacy of intravesical MMC and to also use this agent with an ablative intent. Enhancing tumor response with a sequential therapy is another option that has been investigated, mostly for chemo-immunotherapy wherein the different mechanisms of action of Bacillus of Calmette and Guerìn (BCG) and MMC are combined to achieve a higher response.
