Abstract
We developed a flare prediction model using machine learning, which is optimized to predict the maximum class of flares occurring in the following 24 hr. Machine learning is used to devise algorithms that can learn from and make decisions on a huge amount of data. We used solar observation data during the period 2010–2015, such as vector magnetograms, ultraviolet (UV) emission, and soft X-ray emission taken by the Solar Dynamics Observatory and the Geostationary Operational Environmental Satellite. We detected active regions (ARs) from the full-disk magnetogram, from which ∼60 features were extracted with their time differentials, including magnetic neutral lines, the current helicity, the UV brightening, and the flare history. After standardizing the feature database, we fully shuffled and randomly separated it into two for training and testing. To investigate which algorithm is best for flare prediction, we compared three machine-learning algorithms: the support vector machine, k-nearest neighbors (k-NN), and extremely randomized trees. The prediction score, the true skill statistic, was higher than 0.9 with a fully shuffled data set, which is higher than that for human forecasts. It was found that k-NN has the highest performance among the three algorithms. The ranking of the feature importance showed that previous flare activity is most effective, followed by the length of magnetic neutral lines, the unsigned magnetic flux, the area of UV brightening, and the time differentials of features over 24 hr, all of which are strongly correlated with the flux emergence dynamics in an AR.

Abstract
We present a cosmic void catalog using the large-scale structure galaxy catalog from the Baryon Oscillation Spectroscopic Survey (BOSS). This galaxy catalog is part of the Sloan Digital Sky Survey (SDSS) Data Release 12 and is the final catalog of SDSS-III. We take into account the survey boundaries, masks, and angular and radial selection functions, and apply the ZOBOV void finding algorithm to the Galaxy catalog. We identify a total of 10,643 voids. After making quality cuts to ensure that the voids represent real underdense regions, we obtain 1,228 voids with effective radii spanning the range 20–100

and with central densities that are, on average, 30% of the mean sample density. We release versions of the catalogs both with and without quality cuts. We discuss the basic statistics of voids, such as their size and redshift distributions, and measure the radial density profile of the voids via a stacking technique. In addition, we construct mock void catalogs from 1000 mock galaxy catalogs, and find that the properties of BOSS voids are in good agreement with those in the mock catalogs. We compare the stellar mass distribution of galaxies living inside and outside of the voids, and find no large difference. These BOSS and mock void catalogs are useful for a number of cosmological and galaxy environment studies.
Concilier éthique et performance dans l’économie sociale et solidaire : quelle contribution de la vision stratégique et de la qualité ? Le cas de « A.I.D.E.R »
Authors: Phanuel Dominique , Lemaire Isabelle 
Published: January 2017

En matière d’action publique, le défi à relever, peut-être plus que la performance elle-même, est celui du couplage de l’éthique et de la performance. L’articulation des fins et des moyens se pose non seulement au nom d’une culture des moyens, du résultat et de la performance mais aussi au nom d’un questionnement sur le sens et sur l’éthique. Les outils de gestion, à visée performative, sont sortis des grandes entreprises, pour se diffuser dans l’économie sociale et solidaire. Cette dernière constitue-t-elle, du fait de sa nature et de ses principes, mais aussi grâce à sa capacité d’appropriation de certains outils de gestion, une réponse originale et pertinente à l’association de l’éthique et de la performance ? Cette recherche exploratoire ambitionne d’identifier les signes de cette articulation au travers la vision stratégique du dirigeant et le système de management par la qualité mis en place. L’association « A.I.D.E.R » constitue le support d’une étude de cas de niveau local basé sur des entretiens et sur une analyse du vocabulaire présent dans son manuel qualité.
Des conditions et enjeux de la politisation de l’administration publique au regard de l’ethos public : une étude comparée (Canada/Suisse) de l’expérience des cadres dirigeants
Authors: Fortier Isabelle , Emery Yves , Roldan Rachel 
Published: January 2017

La managérialisation des organisations publiques, sous l’impulsion du nouveau management public (NMP), modifie les relations politico-administratives et remet en question les rôles et identités de ses acteurs. Situés au carrefour des interactions multiples, les cadres dirigeants contribuent à donner sens à l’ethos public et à définir sa spécificité. Par la comparaison (Canada/Suisse), cette recherche aborde la spécificité sous deux angles : la dimension institutionnelle différenciée du fonctionnement étatique et démocratique pour chacun des pays, et la construction des identités des acteurs en lien avec l’ethos public qui s’en dégage. Dans chacun des contextes, nous discutons des conditions et enjeux de la politisation de l’administration à partir des réactions que celles-ci inspirent aux cadres rencontrés et qui expriment ainsi le maintien ou la transformation de l’ethos public.
Le Nouveau Management Public conduit-il à un rapprochement public-privé ? Une analyse à partir des procédures d’évaluation du personnel
Authors: Ientile-Yalenios Jocelyne , Thivant Eric , Roger Alain 
Published: January 2017

Les caractéristiques des systèmes d’évaluation du personnel sont-elles spécifiques au secteur public, ou bien répondent-elles à des normes universelles visant à une homogénéisation des pratiques ? Pour répondre à cette question, nous discutons les résultats de l’analyse lexicométrique des documents qui définissent les conditions d’application de ces systèmes dans deux organisations publiques et deux entreprises privées. Alors que dans les entreprises privées les notions de résultat, d’objectif ou de performance fréquemment reprises évoquent une culture de marché centrée sur des objectifs rationnels, les deux organisations du secteur public étudiées présentent plusieurs caractéristiques des cultures bureaucratiques, mais elles s’en éloignent sur certains points traduisant l’évolution générale du secteur public vers un « Nouveau Management Public » et le développement de la responsabilité et de la flexibilité.
Influence of a Patient-Centered Care Coordination Clinical Module on Student Learning: A Multimethod Study
Authors: Holland Ann E. , Tiffany Jone , Tilton Kathleen , Kleve McCall 
Published: January 2017

Background:
This article reports the results of a study that investigated the influence of an integrated patient centered care coordination (PCCC) clinical curricular module on nursing student learning outcomes. Baccalaureate nursing education must increase its emphasis on the professional nursing role of care coordination to meet changing health care needs, including the ability to practice in community and ambulatory care settings. Little research has been conducted to examine the effect of curricular change for teaching care coordination on student learning outcomes.

Method:
This study used a quasi-experimental mixed-methods design at a university school of nursing, collecting data with a pre–postsurvey, a skills performance instrument, and focus groups.

Results:
The PCCC curricular module significantly and positively affected student learning outcomes, as evidenced by the pre–postsurvey and focus group results.

Conclusion:

Intentional curricular change can make a significant impact on students' knowledge, attitudes, and behaviors related to PCCC. [

Mathematics Competency for Beginning Chemistry Students Through Dimensional Analysis
Authors: Pursell David P. , Forlemu Neville Y. , Anagho Leonard E. 
Published: January 2017

Background:
Mathematics competency in nursing education and practice may be addressed by an instructional variation of the traditional dimensional analysis technique typically presented in beginning chemistry courses.

Method:
The authors studied 73 beginning chemistry students using the typical dimensional analysis technique and the variation technique. Student quantitative problem-solving performance was evaluated.

Results:

Students using the variation technique scored significantly better (18.3 of 20 points,
p
< .0001) on the final examination quantitative titration problem than those who used the typical technique (10.9 of 20 points). American Chemical Society examination scores and in-house assessment indicate that better performing beginning chemistry students were more likely to use the variation technique rather than the typical technique.

Conclusion:

The variation technique may be useful as an alternative instructional approach to enhance beginning chemistry students' mathematics competency and problem-solving ability in both education and practice. [

Published: January 2017

Background:
The lack of safe drinking water is a significant public health threat worldwide. Registered nurses assess the physical environment, including the quality of the water supply, and apply environmental health knowledge to reduce environmental exposures. The purpose of this research brief is to describe a waterborne disease simulation for students enrolled in a public health nursing (PHN) course.

Method:

A total of 157 undergraduate students completed the simulation in teams, using the SBAR (

ssessment-
R
ecommendation) reporting tool. Simulation evaluation consisted of content analysis of the SBAR tools and debriefing notes.

Results:
Student teams completed the simulation and articulated the implications for PHN practice. Student teams discussed assessment findings and primarily recommended four nursing interventions: health teaching focused on water, sanitation, and hygiene; community organizing; collaboration; and advocacy to ensure a safe water supply.

Conclusion:

With advanced planning and collaboration with partners, waterborne disease simulation may enhance PHN education. [

Impacts of White-Nose Syndrome Observed During Long-Term Monitoring of a Midwestern Bat Community
Authors: Pettit Joseph L. , O'Keefe Joy M. 
Published: January 2017

Abstract
White-nose syndrome (WNS) is an emerging fungal disease suspected to have infected Indiana caves in the winter of 2010–2011. This disease places energetic strains on cave-hibernating bats by forcing them to wake and use energy reserves. It has caused &gt;5.5 million bat deaths across eastern North America, and may be the driving force for extinction of certain bat species. White-nose syndrome infection can be identified in hibernacula, but it may be difficult to determine whether bats in a particular area are affected if no known hibernacula exist. Thus, our aim was to use long-term monitoring data to examine changes in a summer population away from hibernacula that may be attributable to WNS effects during winter. We used capture data from a long-term bat-monitoring project in central Indiana with data from 10 repeatedly netted sites consistent across all reproductive periods. We modeled capture data by WNS exposure probability to assess changes in relative abundance of common species and reproductive classes as WNS exposure probability increases. We base exposure probability on a cokriging spatial model that interpolated WNS infection from hibernaculum survey data. The little brown bat Myotis lucifugus, the Indiana bat M. sodalis, and the tri-colored bat Perimyotis subflavus suffered 12.5–79.6% declines; whereas, the big brown bat Eptesicus fuscus, the eastern red bat Lasiurus borealis, and the evening bat Nycticeius humeralis showed 11.5–50.5% increases. We caught more nonreproductive adult females and postlactating females when WNS exposure probabilities were high, suggesting that WNS is influencing reproductive success of affected species. We conclude that, in Indiana, WNS is causing species-specific declines and may have caused the local extinction of M. lucifugus. Furthermore, WNS-affected species appear to be losing pups or forgoing pregnancy. Ongoing long-term monitoring studies, especially those focusing on reproductive success, are needed to measure the ultimate impacts of WNS.
Continuity of Convolution and SIN Groups
Authors: Pachl Jan , Steprans Juris 
Published: January 2017

AbstractLet the measure algebra of a topological group G be equipped with the topology of uniform convergence on bounded right uniformly equicontinuous sets of functions. Convolution is separately continuous on the measure algebra, and it is jointly continuous if and only if G has the SIN property. On the larger space LUC(G)*, which includes the measure algebra, convolution is also jointly continuous if and only if the group has the SIN property, but not separately continuous for many non-SIN groups.
Have precipitation extremes and annual totals been increasing in the world's dry regions over the last 60 years?

Abstract. Daily precipitation extremes and annual totals have increased in large parts of the global land area over the past decades. These observations are consistent with theoretical considerations of a warming climate. However, until recently these trends have not been shown to consistently affect dry regions over land. A recent study, published by Donat et al. (2016), now identified significant increases in annual-maximum daily extreme precipitation (Rx1d) and annual precipitation totals (PRCPTOT) in dry regions. Here, we revisit the applied methods and explore the sensitivity of changes in precipitation extremes and annual totals to alternative choices of defining a dry region (i.e. in terms of aridity as opposed to precipitation characteristics alone). We find that (a) statistical artifacts introduced by data pre-processing based on a time-invariant reference period lead to an overestimation of the reported trends by up to 40 %, and that (b) the reported trends of globally aggregated extremes and annual totals are highly sensitive to the definition of a dry region of the globe. For example, using the same observational dataset, accounting for the statistical artifacts, and based on different aridity-based dryness definitions, we find a reduction in the positive trend of Rx1d from the originally reported +1.6 % decade−1 to +0.2 to +0.9 % decade−1 (period changes for 1981–2010 averages relative to 1951–1980 are reduced to −1.32 to +0.97 % as opposed to +4.85 % in the original study). If we include additional but less homogenized data to cover larger regions, the global trend increases slightly (Rx1d: +0.4 to +1.1 % decade−1), and in this case we can indeed confirm (partly) significant increases in Rx1d. However, these globally aggregated estimates remain uncertain as considerable gaps in long-term observations in the Earth's arid and semi-arid regions remain. In summary, adequate data pre-processing and accounting for uncertainties regarding the definition of dryness are crucial to the quantification of spatially aggregated trends in precipitation extremes in the world's dry regions. In view of the high relevance of the question to many potentially affected stakeholders, we call for a well-reflected choice of specific data processing methods and the inclusion of alternative dryness definitions to guarantee that communicated results related to climate change be robust.

Abstract
Analysis of pesticide residues in irrigated rice grains is important for food security. In this study, we analyzed accelerated solvent extraction (ASE) conditions for the extraction of thiamethoxam and chlorantraniliprole insecticides from rice hulls, rice bran, and polished rice grains. Several variables, including extraction solvent, extraction temperature, extraction pressure, cell size, static extraction time, and sample concentration, were investigated. The average recoveries of the three matrixes were between 89.7 and 109.7% at the fortification level of 0.75 mg/kg. The optimum ASE operating conditions were acetonitrile (100%) as extraction solvent, extraction temperature of 75°C for rice hulls and 100°C for rice bran and polished rice grains, extraction cell pressure of 10.3 MPa, 22 mL cell size, and two extraction cycles. The total extraction time was approximately 25 min. The extracted volume was evaporated to dryness and the residues were redissolved in 2 mL acetonitrile after 1 min of vortex-shaking. Thiamethoxam and chlorantraniliprole were analyzed by ultra-HPLC with tandem MS. In conclusion, ASE in rice hulls, rice bran, and polished rice grains offers the possibility of a fast and simple method for obtaining a quantitative extraction of the studied pesticides.

Published: January 2017

Abstract
Raman spectroscopy (RS) of nasopharyngeal carcinoma (NPC) tissue provides substantial biomolecular information and various biomedicine features for tissue at different stages of cancer development. This study suggested an automatic and quick method for the classification of Raman spectra at different stages of NPC by multivariate statistical analysis. During RS measurement, Raman spectra were acquired from all NPC tissues in two groups of samples: 30 early-stage NPC patients (stages I and II) and 46 advanced-stage NPC patients (stages III and IV). In addition, a tentative diagnostic algorithm comprising principal components analysis and support vector machine was used to effectively classify multivariate data from the Raman spectra to yield sensitivities (70%; 21 of 30 samples) and specificities (91%; 42 of 46 samples) by the leave-one-out cross-validation method. Meaningful chemical compositions in the classification process were then deduced by analyzing the classified mathematical model. This beneficial work provides a great potential clinical method for the automatic classification of NPC stages and the speculation of the chemical compositions for NPC staging.
Chromatographic Determination of Cyclopentolate Hydrochloride and Phenylephrine Hydrochloride in the Presence of Their Potential Degradation Products

Published: January 2017

Abstract
Two sensitive, selective, and precise stability-indicating methods have been developed for the simultaneousdetermination of the active pharmaceutical ingredients cyclopentolate hydrochloride (CLO) and phenylephrine hydrochloride (PHE) in their pure forms and in the presence of their degradation products. The methods were applied for the determination of CLO and PHE in a pharmaceutical formulation. Method A was based on isocratic elution HPLC determination. Separation was achieved using a Waters Spherisorb ODS2 C18 analytical column (5 μm particle size) and a mobile phase of 0.1% heptane-1-sulphonic acid sodium salt in methanol–water (80 + 20, v/v). The flow rate was 1.0 mL/min and detection was performed at 210 nm. Method B was an HPTLC- densitometric method using HPTLC silica gel 60 F254 plates and an optimized mobile phase of ethyl acetate–methanol–ammonia (8 + 2 + 0.1, v/v/v). The separated spots were densitometrically scanned at 210 nm. Polynomial equations were used for regression. The developed methods are suitable for the determination of CLO and PHE in their binary mixture and in the presence of their corresponding degradation products. The two methods were validated in compliance with International Conference on Harmonization guidelines and successfully applied for the determination of CLO and PHE as synthetically prepared in laboratory mixtures and in the presence of their possible degradation products. CLO alkaline degradation products were stated as potential impurities in BritishPharmacopoeia. The degradation products were separated and identified by mass spectra. Postulation of a PHE oxidative degradation pathway was suggested. The obtained resultswere statistically analyzed and compared with those obtained by applying the official methods for both drugs.
