ABSTRACT
We present galaxy stellar mass functions (GSMFs) at z = 4–8 from a rest-frame ultraviolet (UV) selected sample of ∼4500 galaxies, found via photometric redshifts over an area of ∼280 arcmin2 in the Cosmic Assembly Near-infrared Deep Extragalactic Legacy Survey (CANDELS)/Great Observatories Origins Deep Survey (GOODS) fields and the Hubble Ultra Deep Field. The deepest Spitzer/IRAC data to date and the relatively large volume allow us to place a better constraint at both the low- and high-mass ends of the GSMFs compared to previous space-based studies from pre-CANDELS observations. Supplemented by a stacking analysis, we find a linear correlation between the rest-frame UV absolute magnitude at 1500 Å (

) and logarithmic stellar mass (

) that holds for galaxies with

. We use simulations to validate our method of measuring the slope of the

–M
UV relation, finding that the bias is minimized with a hybrid technique combining photometry of individual bright galaxies with stacked photometry for faint galaxies. The resultant measured slopes do not significantly evolve over z = 4–8, while the normalization of the trend exhibits a weak evolution toward lower masses at higher redshift. We combine the

–M
UV distribution with observed rest-frame UV luminosity functions at each redshift to derive the GSMFs, finding that the low-mass-end slope becomes steeper with increasing redshift from

at z = 4 to

at z = 8. The inferred stellar mass density, when integrated over

–1013
M
⊙, increases by a factor of

between z = 7 and z = 4 and is in good agreement with the time integral of the cosmic star formation rate density.

ABSTRACT
In this paper we present the results of a mid-infrared study of G49.5-0.4, or W51A, part of the massive starbirth complex W51. Combining public data from the Spitzer IRAC camera, and Gemini mid-infrared camera T-ReCS at 7.73, 9.69, 12.33, and 24.56 μm, with a spatial resolution of ∼0.″5, we have identified the mid-infrared counterparts of eight ultracompact H ii regions, showing that two radio sources are deeply embedded in molecular clouds and another is a cloud of ionized gas. From the T-ReCS data we have unveiled the central core of the W51 region, revealing massive young stellar candidates. We modeled the spectral energy distribution of the detected sources. The results suggest that the embedded objects are sources with spectral types ranging from B3 to O5, but the majority of the fits indicate stellar objects with B1 spectral types. We also present an extinction map of IRS 2, showing that a region with lower extinction corresponds to the region where a proposed jet of gas has impacted the foreground cloud. From this map, we also derived the total extinction toward the enigmatic source IRS 2E, which amounts to ∼60 mag in the V band. We calculated the color temperature due to thermal emission of the circumstellar dust of the detected sources; the temperatures are in the interval of ∼100–150 K, which corresponds to the emission of dust located at 0.1 pc from the central source. Finally, we show a possible mid-infrared counterpart of a detected source at millimeter wavelengths that was found by Zapata et al. to be a massive young stellar object undergoing a high accretion rate.
USING LEAKED POWER TO MEASURE INTRINSIC AGN POWER SPECTRA OF RED-NOISE TIME SERIES
Authors: Zhu S. F. , Xue Y. Q. 
Published: June 2016

ABSTRACT
Fluxes emitted at different wavebands from active galactic nuclei (AGNs) fluctuate at both long and short timescales. The variation can typically be characterized by a broadband power spectrum, which exhibits a red-noise process at high frequencies. The standard method of estimating the power spectral density (PSD) of AGN variability is easily affected by systematic biases such as red-noise leakage and aliasing, in particular when the observation spans a relatively short period and is gapped. Focusing on the high-frequency PSD that is strongly distorted due to red-noise leakage and usually not significantly affected by aliasing, we develop a novel and observable normalized leakage spectrum (NLS), which sensitively describes the effects of leaked red-noise power on the PSD at different temporal frequencies. Using Monte Carlo simulations, we demonstrate how an AGN underlying PSD sensitively determines the NLS when there is severe red-noise leakage, and thereby how the NLS can be used to effectively constrain the underlying PSD.
KINETIC SIMULATION OF SLOW MAGNETOSONIC WAVES AND QUASI-PERIODIC UPFLOWS IN THE SOLAR CORONA

Published: June 2016

ABSTRACT
Quasi-periodic disturbances of emission-line parameters are frequently observed in the corona. These disturbances propagate upward along the magnetic field with speeds of ∼100 km s−1. This phenomenon has been interpreted as evidence of the propagation of slow magnetosonic waves or has been argued to be a signature of intermittent outflows superposed on the background plasmas. Here we aim to present a new “wave + flow” model to interpret these observations. In our scenario, the oscillatory motion is a slow-mode wave, and the flow is associated with a beam created by the wave–particle interaction owing to Landau resonance. With the help of a kinetic model, we simulate the propagation of slow-mode waves and the generation of beam flows. We find that weak periodic beam flows can be generated by to Landau resonance in the solar corona, and the phase with the strongest blueward asymmetry is ahead of that with the strongest blueshift by about 1/4 period. We also find that the slow wave damps to the level of 1/e after the transit time of two wave periods, owing to Landau damping and Coulomb collisions in our simulation. This damping timescale is similar to that resulting from thermal conduction in the MHD regime. The beam flow is weakened/attenuated with increasing wave period and decreasing wave amplitude since Coulomb collisions become more and more dominant over the wave action. We suggest that this “wave + flow” kinetic model provides an alternative explanation for the observed quasi-periodic propagating perturbations in various parameters in the solar corona.

ABSTRACT
We report on the mass and distance measurements of two single-lens events from the 2015 Spitzer microlensing campaign. With both finite-source effect and microlens parallax measurements, we find that the lens of OGLE-2015-BLG-1268 is very likely a brown dwarf (BD). Assuming that the source star lies behind the same amount of dust as the Bulge red clump, we find the lens is a 45 ± 7

BD at 5.9 ± 1.0 kpc. The lens of of the second event, OGLE-2015-BLG-0763, is a 0.50 ± 0.04

star at 6.9 ± 1.0 kpc. We show that the probability to definitively measure the mass of isolated microlenses is dramatically increased once simultaneous ground- and space-based observations are conducted.
Les sens pluriels de l’émergent chez Pichon-Rivière
Authors: Eiguer Alberto 
Published: June 2016

Dans ce travail, l’auteur étudie le concept d’émergent proposé par E. Pichon-Rivière, il le définit comme une production inconsciente qui surgit à la suite de la confrontation entre forces, tendances, situations ou subjectivités. Il l’associe à une autre proposition de cet analyste : celle du lien intersubjectif qui se constitue entre deux personnes en interfonctionnement. L’émergent se manifeste dans un contexte de totalité ; il apparaît comme une nouveauté, une synthèse dialectique, tel le trait d’humour, le lapsus, l’acte manqué, le rêve rapporté en séance et les associations du patient après l’interprétation où la réaction du patient traduit l’efficacité de celle-ci. Pour confirmer le statut de concept analytique, l’émergent doit remplir trois conditions : est-il une formation de l’inconscient, le produit d’un travail psychique et le résultat d’une formation de compromis ? Dans l’article, l’émergent est examiné avec soin : il paraît remplir ces conditions. L’émergent et le lien soulignent le mouvement, le changement ; ce qui vient après détermine la séquence globale. Faisant partie de l’intersubjectivité, l’analyste est impliqué pleinement dans la cure et amené à travailler en lui ce qu’il y vit. Sa fonction analytique vibre avec les sons de son auto-analyse. Pichon-Rivière a appliqué sa découverte à la situation analytique et à la pathogénie familiale de la psychose. L’exemple d’un lapsus de l’analyste en séance de thérapie familiale permet d’illustrer le propos.
Fratrie et création
Authors: Sourgen Jean-Louis 
Published: June 2016

Le rôle de la fratrie dans la création littéraire, déjà envisagé par Freud à propos de la Gradiva se manifeste avec éclat lorsqu’on chemine en associant aux œuvres les écrits intimes, les correspondances, les données biographiques. Des aspects communs se dégagent : mouvements de fusion et d’individuation, recherche d’une enveloppe commune dans l’élaboration de deuils précoces, quête d’un jumeau ou d’un double lors de l’adolescence ainsi que des rivalités et des étayages mutuels. Un espace de création partagé constitue souvent une issue face à l’envahissement des affects dépressifs. De l’ensemble se dégage l’idée que la création n’est pas seulement un processus individuel, mais aussi un processus groupal dont la fratrie constitue un élément important et parfois essentiel.
Validation of the Mobile Information Software Evaluation Tool (MISET) With Nursing Students
Authors: Secco M. Loretta , Furlong Karen E. , Doyle Glynda , Bailey Judy 
Published: June 2016

Background:

This study evaluated the Mobile Information Software Evaluation Tool (MISET) with a sample of Canadian undergraduate nursing students (
N
= 240).

Method:
Psychometric analyses determined how well the MISET assessed the extent that nursing students find mobile device-based information resources useful and supportive of learning in the clinical and classroom settings.

Results:
The MISET has a valid three-factor structure with high explained variance (74.7%). Internal consistency reliabilities were high for the MISET total (.90) and three subscales: Usefulness/Helpfulness, Information Literacy Support, and Use of Evidence-Based Sources (.87 to .94). Construct validity evidence included significantly higher mean total MISET, Helpfulness/Usefulness, and Information Literacy Support scores for senior students and those with higher computer competence.

Conclusion:

The MISET is a promising tool to evaluate mobile information technologies and information literacy support; however, longitudinal assessment of changes in scores over time would determine scale sensitivity and responsiveness. [

Computer-Assisted Concept Mapping: Visual Aids for Knowledge Construction
Authors: Mammen Jennifer R. 
Published: June 2016

Background:
Concept mapping is a visual representation of ideas that facilitates critical thinking and is applicable to many areas of nursing education. Computer-assisted concept maps are more flexible and less constrained than traditional paper methods, allowing for analysis and synthesis of complex topics and larger amounts of data. Ability to iteratively revise and collaboratively create computerized maps can contribute to enhanced interpersonal learning. However, there is limited awareness of free software that can support these types of applications. This educational brief examines affordances and limitations of computer-assisted concept maps and reviews free software for development of complex, collaborative malleable maps.

Results:
Free software, such as VUE, XMind, MindMaple, and others, can substantially contribute to the utility of concept mapping for nursing education.

Conclusions:

Computerized concept-mapping is an important tool for nursing and is likely to hold greater benefit for students and faculty than traditional pen-and-paper methods alone. [

Arts-Based Learning: A New Approach to Nursing Education Using Andragogy
Authors: Nguyen Megan , Miranda Joyal , Lapum Jennifer , Donald Faith 
Published: June 2016

Background:
Learner-oriented strategies focusing on learning processes are needed to prepare nursing students for complex practice situations. An arts-based learning approach uses art to nurture cognitive and emotional learning. Knowles' theory of andragogy aims to develop the skill of learning and can inform the process of implementing arts-based learning. This article explores the use and evaluation of andragogy-informed arts-based learning for teaching nursing theory at the undergraduate level.

Method:
Arts-based learning activities were implemented and then evaluated by students and instructors using anonymous questionnaires.

Results:
Most students reported that the activities promoted learning. All instructors indicated an interest in integrating arts-based learning into the curricula. Facilitators and barriers to mainstreaming arts-based learning were highlighted. Findings stimulate implications for prospective research and education.

Conclusion:

Findings suggest that arts-based learning approaches enhance learning by supporting deep inquiry and different learning styles. Further exploration of andragogy-informed arts-based learning in nursing and other disciplines is warranted. [

Expression of the endocannabinoid receptors in human fascial tissue
Authors: Fede C. , Albertin G. , Petrelli L. , Sfriso M.M. , Biz C. , De Caro R. , Stecco C. 
Published: June 2016

Cannabinoid receptors have been localized in the central and peripheral nervous system as well as on cells of the immune system, but recent studies on animal tissue gave evidence for the presence of cannabinoid receptors in different types of tissues. Their presence was supposed also in myofascial tissue, suggesting that the endocannabinoid system may help resolve myofascial trigger points and relieve symptoms of fibromyalgia. However, until now the expression of CB1 (cannabinoid receptor 1) and CB2 (cannabinoid receptor 2) in fasciae has not yet been established. Small samples of fascia were collected from volunteers patients during orthopedic surgery. For each sample were done a cell isolation, immunohistochemical investigation (CB1 and CB2 antibodies) and real time RT-PCR to detect the expression of CB1 and CB2. Both cannabinoid receptors are expressed in human fascia and in human fascial fibroblasts culture cells, although to a lesser extent than the control gene. We can assume that the expression of mRNA and protein of CB1 and CB2 receptors in fascial tissue are concentrated into the fibroblasts.Â This is the first demonstration that the fibroblasts of the muscular fasciae express CB1 and CB2. The presence of these receptors could help to provide a description of cannabinoid receptors distribution and to better explain the role of fasciae as pain generator and the efficacy of some fascial treatments. Indeed the endocannabinoid receptors of fascial fibroblasts can contribute to modulate the fascial fibrosis and inflammation.

‘Poems look like a mathematical equation’: Assessment in poetry education
Authors: Xerri Daniel 
Published: June 2016

<p>This article considers the influence that assessment exerts on poetry education. By means of research conducted in a post-16 educational context in Malta, it shows that teachers’ and students’ practices in the poetry lesson are determined by the kind of examinations that candidates sit for. When the mode of assessment is constituted solely by the traditional essay test that excludes students’ personal response, their engagement with poetry might be impaired and teachers’ role becomes highly pronounced. The article demonstrates how assessment plays a key role in governing teachers’ and students’ practices in the classroom. However, it is also argued that other factors are equally responsible for their approach to poetry.</p>
How home HIV testing and counselling with follow‐up support achieves high testing coverage and linkage to treatment and prevention: a qualitative analysis from Uganda

IntroductionThe successes of HIV treatment scale‐up and the availability of new prevention tools have raised hopes that the epidemic can finally be controlled and ended. Reduction in HIV incidence and control of the epidemic requires high testing rates at population levels, followed by linkage to treatment or prevention. As effective linkage strategies are identified, it becomes important to understand how these strategies work. We use qualitative data from The Linkages Study, a recent community intervention trial of community‐based testing with linkage interventions in sub‐Saharan Africa, to show how lay counsellor home HIV testing and counselling (home HTC) with follow‐up support leads to linkage to clinic‐based HIV treatment and medical male circumcision services.MethodsWe conducted 99 semi‐structured individual interviews with study participants and three focus groups with 16 lay counsellors in Kabwohe, Sheema District, Uganda. The participant sample included both HIV+ men and women (N=47) and HIV‐uncircumcised men (N=52). Interview and focus group audio‐recordings were translated and transcribed. Each transcript was summarized. The summaries were analyzed inductively to identify emergent themes. Thematic concepts were grouped to develop general constructs and framing propositional statements.ResultsTrial participants expressed interest in linking to clinic‐based services at testing, but faced obstacles that eroded their initial enthusiasm. Follow‐up support by lay counsellors intervened to restore interest and inspire action. Together, home HTC and follow‐up support improved morale, created a desire to reciprocate, and provided reassurance that services were trustworthy. In different ways, these functions built links to the health service system. They worked to strengthen individuals’ general sense of capability, while making the idea of accessing services more manageable and familiar, thus reducing linkage barriers.ConclusionsHome HTC with follow‐up support leads to linkage by building “social bridges,” interpersonal connections established and developed through repeated face‐to‐face contact between counsellors and prospective users of HIV treatment and male circumcision services. Social bridges link communities to the service system, inspiring individuals to overcome obstacles and access care.
