Accurate and efficient query clustering via top ranked search results
Authors: Hong Yuan , Vaidya Jaideep , Lu Haibing , Liu Wen Ming 
Published: April 2016

To make the search engine more user-friendly, commercial search engines commonly develop applications to provide suggestion or recommendation for every posed query. Clustering semantically similar queries acts as an essential prerequisite to function well in those applications. However, clustering queries effectively is quite challenging, since they are usually short, incomplete and ambiguous. Existing prevalent clustering methods, such as K-Means or DBSCAN cannot guarantee good performance in such a highly dimensional environment. Through analyzing users’ click-through query logs, hierarchical agglomerative clustering gives good results but is computationally quite expensive. This paper identifies a novel feature for clustering search queries based on a key insight – queries’ top ranked search results can themselves be used to quantify query similarity. After investigating such feature, we propose a new similarity metric for comparing those diverse queries. This facilitates us to develop two very efficient and accurate algorithms integrated in query clustering. We conduct comprehensive experiments to compare the accuracy of our approach against the known baselines along two dimensions: 1) quantifying the cohesion/separation of clustered queries, and 2) justifying the results by real-world Internet users. The experimental results demonstrate that our two algorithms and the similarity metric can generate more accurate results within a significantly shorter time.
OBSERVATION OF A QUASIPERIODIC PULSATION IN HARD X-RAY, RADIO, AND EXTREME-ULTRAVIOLET WAVELENGTHS

Published: April 2016

ABSTRACT
We present a multiwavelength analysis of a quasiperiodic pulsation (QPP) observed in the hard X-ray (HXR), radio, and extreme-ultraviolet (EUV) channels during an M1.9 flare that occurred on 2011 September 23–24. The nonthermal HXR emission in 25–50 keV observed by RHESSI shows five distinct impulsive peaks of decaying amplitude with a period of about 3 minutes. A similar QPP was observed in the microwave emission recorded by the Nobeyama Radioheliograph and Polarimeter in the 2, 3.75, 9.4, and 17 GHz channels. Interestingly, the 3-minute QPP was also observed in the metric and decimetric radio frequencies (25–180, 245, 610 MHz) as repetitive type III bursts. Multiwavelength observations from the Solar Dynamics Observatory/Atmospheric Image Assembly, Hinode/SOT, and Solar TErrestrial RElations Observatory/SECCHI suggest a fan-spine topology at the eruption site, associated with the formation of a quasi-circular ribbon during the flare. A small filament was observed below the fan loops before the flare onset. The filament rose slowly and interacted with the ambient field. This behavior was followed by an untwisting motion of the filament. Two different structures of the filament showed an approximately 3-minute periodic alternate rotation in the clockwise and counterclockwise directions. The 3-minute QPP was found to highly correlate with 3-minute oscillations in a nearby sunspot. We suggest that the periodic reconnection (modulated either by a sunspot slow-mode wave or by an untwisting filament) at a magnetic null point most likely causes the repetitive particle acceleration, generating the QPP observed in HXR, microwave, and type III radio bursts.
ALMA 0.1–0.2 arcsec RESOLUTION IMAGING OF THE NGC 1068 NUCLEUS: COMPACT DENSE MOLECULAR GAS EMISSION AT THE PUTATIVE AGN LOCATION

Published: April 2016

ABSTRACT
We present the results of our ALMA Cycle 2 high angular resolution (0.″1–0.″2) observations of the nuclear region of the nearby well-studied type-2 active galactic nucleus (AGN), NGC 1068, at HCN J = 3–2 and HCO+
J = 3–2 emission lines. For the first time, due to a higher angular resolution than previous studies, we clearly detected dense molecular gas emission at the putative AGN location, identified as a ∼1.1 mm (∼266 GHz) continuum emission peak, by separating this emission from brighter emission located at 0.″5–2.″0 on the eastern and western sides of the AGN. The estimated intrinsic molecular emission size and dense molecular mass, which are thought to be associated with the putative dusty molecular torus around an AGN, were ∼10 pc and ∼several × 105
M
⊙, respectively. HCN-to-HCO+
J = 3–2 flux ratios substantially higher than unity were found throughout the nuclear region of NGC 1068. The continuum emission displayed an elongated morphology along the direction of the radio jet located at the northern side of the AGN, as well as a weak spatially-resolved component at ∼2.″0 on the southwestern side of the AGN. The latter component most likely originated from star formation, with the estimated luminosity more than one order of magnitude lower than the luminosity of the central AGN. No vibrationally excited (v
2 = 1f) J = 3–2 emission lines were detected for HCN and HCO+ across the field of view.
ULTRAFAST OUTFLOWS FROM BLACK HOLE MERGERS WITH A MINIDISK

Published: April 2016

ABSTRACT
Recently, the direct detection of gravitational waves from black hole (BH) mergers was announced by the Advanced LIGO Collaboration. Multi-messenger counterparts of stellar-mass BH mergers are of interest, and it had been suggested that a small disk or celestial body may be involved in the binary of two BHs. To test such possibilities, we consider the fate of a wind powered by an active minidisk in a relatively short, super-Eddington accretion episode onto a BH with ∼10–100 solar masses. We show that its thermal emission could be seen as a fast optical transient with the duration from hours to days. We also find that the coasting outflow forms external shocks due to interaction with the interstellar medium, whose synchrotron emission might be expected in the radio band on a timescale of years. Finally, we also discuss a possible jet component and the associated high-energy neutrino emission as well as ultra-high-energy cosmic-ray acceleration.

Background Antiretroviral (ART) drugs have been associated with higher triglycerides (TG), higher total cholesterol (TC) and lower high-density lipoprotein cholesterol (HDL-C) levels. Associations between lipid levels with HIV viraemia and immunosuppression in the presence of ART remain unclear. Methods Participants from the D:A:D study with at least one TG/TC/HDL-C measurement were included. Linear mixed effect models were used to determine the association of ART, viral load (VL), nadir and current CD4+ T-cell count and previous AIDS diagnosis with lipids. Results Of 49,717 participants, 90%, 92% and 80% contributed at least one TG/TC/HDL-C measurement (median follow-up 6.8, 6.8 and 5.0 years, respectively). Predicted mean (95% CI) baseline levels for TG, TC and HDL-C (mmol/l), were 2.10 (2.05, 2.14), 4.94 (4.91, 4.98) and 1.08 (1.07, 1.10), respectively. Lopinavir was associated with the worst TG profile, (27.2% higher levels compared to atazanavir; 95% CI 25.2%, 29.2%), and darunavir had a similar profile as atazanavir. The nucleoside pair lamivudine/tenofovir was associated with the most favourable TG profile (-2.8%; -3.5%, -2.0%) compared with emtricitabine/tenofovir, whereas lamivudine/abacavir (+10.2%; +9.3%, +11.2%) and lamivudine/ stavudine (+8.0%; +6.9%, +9.0%), were associated with the worst. Raltegravir was associated with lower TG (-5.2%; -6.4%, -3.9%), and nevirapine had a more favourable HDL-C profile (+11.3%; +10.8%, +11.7%) than efavirenz (+5.3%; 5.0%, 5.7%), compared to atazanavir. Higher VLs were associated with lower TG/TC/HDL-C, whereas higher CD4+ T-cell counts were associated with higher TG/TC/HDL-C. Conclusions TG, TC and HDL-C levels, which generally improved over time, are dependent on ART, viraemia and, to a lesser extent, immunosuppression.
Macro-invertebrate Biodiversity of a Coastal Prairie with Vernal Pool Habitat
Authors: Fiesler Emile , Drake Tracy 
Published: April 2016

The California Coastal Prairie has the highest biodiversity of North America's grasslands, but also has the highest percentage of urbanization. The most urbanized part of the California Coastal Prairie is its southernmost area, in Los Angeles County. This southernmost region, known as the Los Angeles Coastal Prairie, was historically dotted with vernal pools, and has a unique biodiverse composition. More than 99.5% of its estimated original 95 km2 (23,475 acres), as well as almost all its vernal pool complexes, have been lost to urbanization.
The Madrona Marsh Preserve, in Torrance, California, safeguards approximately 18 hectares (44 acres) of Los Angeles Coastal Prairie and includes a complex of vernal pools. Its aquatic biodiversity had been studied, predominantly to genus level, but its terrestrial macro-invertebrates were virtually unknown, aside from butterfly, dragonfly, and damselfly observations.
In order to better understand the biodiversity at the Madrona Marsh Preserve, a minimally-invasive macro-invertebrate inventory was conducted. The results of this inventory, with 689 invertebrate organisms recorded, covering eight phyla, 13 classes, 39 orders, and 222 families, are presented in this document.
« Tenir toujours fortement comme les deux bouts de la chaîne »
Authors: Naszályi Philippe 
Published: April 2016

Ce numéro double du cœur de l’année du cinquantenaire et qui parait avec retard, est symbolique de ce que notre revue depuis sa création en 1965, a toujours essayé de faire : Produire une recherche et non pas des publications. C’est une lourde de tâche que de « tenir toujours fortement comme les deux bouts de la chaîne quoiqu’on ne voit pas toujours par où l’enchainement se continue » pour reprendre la formule célèbre de Bossuet. Lorsque « le meilleur économiste de France », Raymond Barre, alors Premier ministre, lui a décerné ce titre, c’était parce qu’elle se distinguait de ces consœurs, par une originalité, une liberté de ton et un choix de faire de la gestion une matière vivante en phase avec les évolutions des entreprises – rappelons qu’elle s’appelait alors : direction et gestion des entreprises. Ce numéro 273-274 présente donc en troisième partie, un cahier de recherche fruit d’un colloque. Nous le devons à une collaboration entre un laboratoire universitaire jeune, le Litem , ici sa branche Tem, conduite par Jean-Luc Moriceau et Isabela Paes et un laboratoire privé, Umalis sous la conduite de Julien Billion et de Géraldine Guérillot. Il traite de La déconstruction créatrice du travail : Innovations, opportunités et pièges . Les six articles sélectionnés, émanent de jeunes chercheurs, et sont à bien des égards, décoiffants. Ils apportent une réflexion pluridisciplinaire que nous ne cessons d’appeler de nos vœux pour sortir de la « scolastique » éculée, néo-libérale ou néo-marxiste. Clin d’œil, ces articles innovants, se placent à la fin d’un numéro dont le premier dossier, est justement consacré aux normes et mesures. Aucune contradiction dans ce choix , mais l’application des « deux bouts de la chaîne ». Cinq forts articles charpentent cette réflexion où normes et mesures valident ou non, la performance dans le cadre multipolaire des économies régionales du monde. Le lien entre les « deux bouts de la chaîne », que sont le dossier initial et le cahier final, est naturellement constitué par une transition sur l’entreprise. Entreprendre et environnement turbulent est un petit bijou enchâssé. Les trois articles que l’on doit à des auteurs éprouvés, traitent successivement de l’entrepreneuriat dans son concept, de problèmes de finance notamment dans ce qui constitue la base de l’entrepreneuriat que sont les TPE, et « finis coronat opus », assure la transition avec le cahier final, par une remarquable analyse de discours... pour les plans dits de sauvegarde de l’emploi. L’initiative créatrice, les moyens et les hommes pour la mettre en action, c’est bien l’entreprise !
Restructurations et représentation de la performance :
Authors: Boutant Jennifer , Verdier Marie-Anne 
Published: April 2016

Si les travaux académiques considèrent désormais la performance comme un concept global qui intègre les attentes de l’ensemble des parties prenantes de l’entreprise, la question est de savoir quelle représentation de la performance est donnée lors de restructurations. Les résultats, obtenus à partir de l’analyse de 1 514 articles de presse entre 1997 et 2011, révèlent une représentation de la performance fondée sur trois dimensions : sociale, financière et économique. En outre, s’ils permettent d’observer une évolution de la place accordée à ces trois dimensions, nous ne pouvons conclure à l’émergence d’une représentation globale de la performance.
Analyse de discours :
Authors: Francois-Philip de Saint-Julien Delphine 
Published: April 2016

Cet article poursuit nos recherches sur les restructurations d’entreprise et se centre sur l’analyse du contenu des textes des plans de sauvegarde de l’emploi, négociés par les parties prenantes. À partir d’une analyse propositionnelle du discours et d’une analyse cognito-discursive réalisées avec le logiciel Tropes©, nous pouvons souligner l’existence de propositions remarquables, d’indicateurs langagiers, notamment sous la forme de trois principaux épisodes constitués de rafales d’occurrences, hiérarchisant les choix prioritaires et privilégiés par les parties prenantes. Le premier est centré sur la mobilité, ses aspects financiers et les modalités d’une cellule de reclassement, organisant une véritable expatriation nationale ; le deuxième repose sur le volontariat et le troisième sur le congé de reclassement. Ces épisodes proposent à la fois des éléments cognitifs, procéduraux et/ou interactionnels, afin de construire un champ de possibles favorisant l’employabilité des salariés impactés par la restructuration et le PSE.
La construction de soi dans le portage salarial
Authors: Moriceau Jean-Luc , Paes Isabela , Guérillot Géraldine 
Published: April 2016

Comment se construisent les identités dans les nouvelles formes d’emploi, tel le portage salarial, qui brouillent les frontières et repères entre salariat, travail indépendant et entrepreneuriat ? Une enquête qualitative exploratoire suit le parcours et les affects de cadres portés et s’interroge sur leur construction de soi. Elle dessine le portrait de portés inventant leur chemin pour exercer à leur manière leur expertise, au sein d’un discours libéral, ayant besoin de support, parfois doutant ou angoissés. Ce qui se joue est pour eux un possible accroissement de « capabilités », un mode de vie et une forme de subjectivité mais il reste à réfléchir sur les évolutions sociales liées à ces nouvelles formes d’emploi.
Des ouvriers travailleurs aux makers créatifs :
Authors: Bazin Yoann 
Published: April 2016

Cet article se propose de confronter l’ouvrage de Chris Anderson : Makers - dans lequel il annonce une nouvelle révolution industrielle faite avant tout de travail créatif et de collaborations innovantes – à deux critiques : l’une étymologique et l’autre anthropologique. Faisant émerger deux « fils » sémantiques – aliénation et réalisation -, la critique étymologique se révélera congruente aux récits de travailleurs manuels. On verra alors que l’expérience quotidienne du travail est bien faite de ces deux fils, non pas l’un ou l’autre, ni l’un puis l’autre, mais bien l’un et l’autre concomitamment. L’idée d’un travailleur purement bricoleur et créatif de Ch. Anderson se révèle alors, non pas fausse, mais fondamentalement partielle et partiale.
Work Factors of Importance to Adjunct Nursing Faculty
Authors: Elder Stacie J. , Svoboda Gwen , Ryan Linda A. , Fitzgerald Kathleen 
Published: April 2016

Background:
The use of adjunct faculty has increased exponentially in the past decade. It is essential that resources to retain adjuncts are identified and made available to adjunct faculty. To identify the appropriate factors, it is essential to discover what nursing adjunct instructors perceive to be the factors of importance to their work role. The purpose of the article was to determine the perceived factors of importance and availability of work role needs of adjunct faculty.

Method:
A quantitative, exploratory design was developed, using an anonymous online Adjunct Instructor Likert Scale Survey. The sample included participating adjunct instructors from a possible total of 91 midsized, midwestern baccalaureate nursing programs.

Results:

Fourteen of 18 pairs were significantly different (
p
< .05) in adjunct perception.

Conclusion:

Using these data, colleges of nursing may be able to identify adjunct work factors in that can be improved to increase adjunct faculty recruitment, satisfaction, and retention. [

Stakeholder Perceptions, Learning Opportunities, and Student Outcomes in Three Clinical Learning Models
Authors: Hendricks Susan , DeMeester Deborah , Stephenson Evelyn , Welch Janet 
Published: April 2016

Background:
Understanding the strengths and challenges of various clinical models is important for nursing education.

Method:
Three long-standing clinical models (preceptored, hybrid, and traditional) were compared on several outcome measures related to satisfaction, learning opportunities, and student outcomes. Students, faculty, and preceptors participated in this study.

Results:
Although no differences were noted in satisfaction or standardized examination scores, students in the preceptored clinical model were able to practice more psychomotor skills. Although participants in the preceptored model reported spending more time communicating with staff nurses than did those in the other models, students in the traditional model spent more time with faculty. No differences were noted among groups in student clinical observation time.

Conclusion:

All clinical learning models were focused on how clinical time was structured, without an emphasis on how faculty and preceptors work with students to develop nursing clinical reasoning skills. Identifying methodology to impact thinking in the clinical environment is a key next step. [

Senior Nursing Students' Perceptions of Caring for Patients at the End of Life
Authors: Colley Sharon L. 
Published: April 2016

Background:
Nursing students often feel unprepared to provide end-of-life care. Studies have examined students' learning outcomes and attitudes regarding end-of-life care, but it is unclear how students perceived their nursing program prepared them in both knowledge and confidence. Such research could help inform curricula revisions.

Method:
This pilot study used a primarily qualitative approach with narrative questions and quantitative survey questions to a lesser degree. Seventy-one students from three baccalaureate nursing cohorts were participants.

Results:
Five themes became apparent: Students Have Confidence in Provision of Physical Care, Students Lack Confidence in Provision of Emotional Care, Students Experience Stress and Lack of Knowledge When Caring for Families, Students Have Concern They Will Be Too Emotionally Involved, and Students Feel Personal Experiences Enhance Their Confidence.

Conclusion:

Student perceptions are important to consider when revising curricula to enhance learning and promote confidence in addressing emotional care at the end of life. [

Building Graduate Student Capacity as Future Researchers Through a Research and Training Award Program
Authors: Cepanec Diane , Humphries Amanda , Rieger Kendra L. , Marshall Shelley , Londono Yenly , Clarke Diana 
Published: April 2016

Background:
With the global shortage of doctor of philosophy-prepared nursing faculty and an aging nursing professorate, the nursing profession is at risk of having fewer nurses doing research and fewer faculty to supervise the next generation of nurse researchers.

Method:
A research training award for graduate nursing students was piloted with the intent of providing a research-intensive experiential learning opportunity that would contribute to graduate students' future roles as nurse researchers. This article describes the program design, implementation, and evaluation.

Findings:
The Graduate Student Research Training Awards afforded students an opportunity to develop research and methodologic skills and achieve student-centered outcomes. These awards build their capacity as future researchers by both empowering them and increasing their confidence in research. The input and evaluation from graduate students was integral to the success of the program.

Conclusion:

Graduate student research training awards can be a valuable experiential learning opportunity in research intensive graduate programs. [

Using Interactive Video-Based Teaching to Improve Nursing Students' Ability to Provide Patient-Centered Discharge Teaching
Authors: Blazeck Alice M. , Katrancha Elizabeth , Drahnak Dawn , Sowko Lucille Ann , Faett Becky 
Published: April 2016

Background:
Nursing students rarely are afforded the opportunity to provide discharge teaching in the acute care environment, especially at the sophomore level.

Method:
Three video modules were developed that presented examples of effective and ineffective education for patients with complex chronic conditions. Students viewed modules during postconference using portable technology. A training manual that included objectives, lesson plans, evidence-based teaching points, and a discussion model guided presentation.

Results:
The modules were presented to 216 sophomore nursing students. Following course completion, 20 students and 10 faculty were randomly selected to participate in two focus groups. Students commented positively on the format and illustration of effective teaching. Faculty rated the teaching strategy positively and the format as easy to use.

Conclusion:

Interactive video modules can be used to foster patient teaching skills early in the nursing curriculum. Future studies are needed to evaluate the ability to transfer skills learned to the clinical setting. [
