Les enjeux cruciaux du recrutement pour les organisations hybrides : les enseignements à tirer d’une étude sur les Scop
Authors: Juban Jean-Yves , Charmettant Hervé , Magne Nathalie 
Published: January 2016

L’étude de terrain menée sur une quarantaine de Scop de la région Rhône-Alpes montre qu’elles peuvent être analysées comme des organisations hybrides, mettant en œuvre un double projet : économique et socio-politique. Nos observations confirment que les enjeux du recrutement y sont particulièrement importants et mettent en évidence la diversité des pratiques des Scop afin de répondre à ces enjeux. Nous nous interrogeons par ailleurs sur celles qui semblent mieux à même de garantir la soutenabilité de leur double projet. Parmi ce que nous identifions comme les bonnes pratiques, le « couplage sélectif » semble une voie peu explorée mais plus appropriée que le « compromis » ou le « découplage ».
Transformative Experience: Developing Competence in Novice Nursing Faculty
Authors: Cooley Shirley S. , De Gagne Jennie C. 
Published: January 2016

Background:
The nursing faculty shortage has led to an increasing number of master's-prepared clinical nurse experts becoming nursing faculty to teach prelicensure nursing students, often without adequate preparation for the complex specialized role of an academic nurse educator.

Method:
A hermeneutic phenomenological qualitative study was designed to gain insight about novice nursing faculty's experience in academia, to examine their perceptions of facilitators and barriers to the development of nurse educators' practice competence, and to identify transformative learning experiences related to novice faculty development. The data consisted of audio recordings and verbatim transcripts of interviews, along with journal data describing day-to-day experiences as novice nurse academics. Data were analyzed using Moustakas' seven-step process.

Results:
Facilitators and barriers, along with characteristics of transformative learning experiences, were identified. An essential combination of facilitating factors, mentorship, and internship programs was discovered.

Conclusion:

Internship programs are a necessary link in creating academic environments that contribute to the development of competence in novice nursing faculty. [

Authors: Raterink Ginger 
Published: January 2016

Background:

Critical thinking, clinical decision making, and critical reflection have been identified as skills required of nurses in every clinical situation. The
Educating Nurses: A Call for Radical Transformation
report suggested that critical reflection is a key to improving the educational process. Reflective journaling is a tool that helps develop such skills.

Method:
This article presents the tool of reflective journaling and the use of this process by educators working with students. It describes the use of reflective journaling in graduate nursing education, as well as a scoring process to evaluate the reflection and provide feedback.

Results:
Students and faculty found the journaling to be helpful for reflection of a clinical situation focused on critical thinking skill development. The rubric scoring tool provided faculty with a method for feedback.

Conclusion:

Reflective journaling is a tool that faculty and students can use to develop critical thinking skills for the role of the advanced practice RN. A rubric scoring system offers a consistent format for feedback. [

Use of Visual Narrative Illustrations to Teach Pathophysiology Concepts to Nursing Students
Authors: El Hussein Mohamed Toufic , Salyers Vincent , Osuji Joseph 
Published: January 2016

Background:
The care of patients with acute and chronic illnesses requires nurses to fully understand the underlying pathophysiology associated with disease processes. Although mastering a pathophysiology course is a strong predictor of student success in nursing programs, it is a course with which students and new nurses most often struggle.

Method:
The authors describe a teaching innovation—visual narrative illustration (VNI)—and demonstrate how VNIs are used to teach complex pathophysiology concepts to nursing students.

Results:
The consistent positive feedback regarding the VNIs that have already been implemented in the pathophysiology course prompted the authors to systematically and formally study the impact of this innovative approach on student learning and knowledge retention.

Conclusion:

Use of VNI is an innovative teaching strategy that has the potential to augment other course materials and bridge some of the knowledge gaps that challenge nursing students from fully understanding pathophysiologic concepts. [

Aging in Community: Developing a More Holistic Approach to Enhance Older Adults' Well-Being
Authors: Davitt Joan K. , Madigan Elizabeth A. , Rantz Marilyn , Skemp Lisa 
Published: January 2016

Public health advances have contributed to increased longevity; however, individuals are more likely to live longer with multiple chronic conditions. The existing health care system primarily focuses on treating disease rather than addressing well-being as a holistic construct that includes physical, social, and environmental components. The current commentary emphasizes the importance of supporting healthy active aging and aging in community. The barriers to aging in community and the state of the intervention science in response to this problem are discussed, and recommendations for future research are provided. Active aging is more than managing illness or care transitions—it promotes engagement, participation, dignity, self-fulfillment, self-determination, and support for older adults. To support aging in community and healthy active aging, a paradigm shift is needed in how the well-being of older adults is thought about and supported.[Res Gerontol Nurs. 2016; 9(1):6–13.]

Congruencias y discrepancias entre concepciones y prácticas evaluativas con uso de TIC
Authors: Moreno Romero Liliana Leticia , Rochera Villach María José 
Published: January 2016

Este estudio analiza las congruencias y discrepancias entre lo que los profesores piensan acerca de la evaluación y feedback con uso de las Tecnologías de la Información y Comunicación (TIC) y lo que, finalmente concretan en sus prácticas, en un contexto poco estudiado como es la Educación Secundaria Obligatoria (ESO). Participaron dos profesoras, una de matemáticas y otra, de inglés. Los resultados muestran más congruencias que discrepancias entre las creencias de las profesoras y sus prácticas evaluativas. Además, las congruencias relacionadas con el polo pedagógico de la evaluación se hayan influenciadas por dos factores clave: la amplia formación docente y la existencia de un contexto favorable.

Mathematical Models for the Propagation of Stress Waves in Elastic Rods: Exact Solutions and Numerical Simulation
Authors: Tenkam H. M. , Shatalov M. , Fedotov I. , Anguelov R. 
Published: January 2016

AbstractIn this work, the Bishop and Love models for longitudinal vibrations are adopted to study the dynamics of isotropic rods with conical and exponential cross-sections. Exact solutions of both models are derived, using appropriate transformations. The analytical solutions of these two models are obtained in terms of generalised hypergeometric functions and Legendre spherical functions respectively. The exact solution of Love model for a rod with exponential cross-section is expressed as a sum of Gauss hypergeometric functions. The models are solved numerically by using the method of lines to reduce the original PDE to a system of ODEs. The accuracy of the numerical approximations is studied in the case of special solutions.
Equivalent a Posteriori Error Estimator of Spectral Approximation for Control Problems with Integral Control-State Constraints in One Dimension
Authors: Huang Fenglin , Chen Yanping , Shi Xiulian 
Published: January 2016

Abstract.In this paper, we investigate the Galerkin spectral approximation for elliptic control problems with integral control and state constraints. Firstly, an a posteriori error estimator is established,which can be acted as the equivalent indicatorwith explicit expression. Secondly, appropriate base functions of the discrete spacesmake it is probable to solve the discrete system. Numerical test indicates the reliability and efficiency of the estimator, and shows the proposed method is competitive for this class of control problems. These discussions can certainly be extended to two- and three-dimensional cases.
A Goal-Oriented Adaptive Moreau-Yosida Algorithm for Control- and State-Constrained Elliptic Control Problems
Authors: Günther Andreas , Tber Moulay Hicham 
Published: January 2016

AbstractIn this work, we develop an adaptive algorithm for solving elliptic optimal control problems with simultaneously appearing state and control constraints. The algorithm combines a Moreau-Yosida technique for handling state constraints with a semi-smooth Newton method for solving the optimality systems of the regularized sub-problems. The state and adjoint variables are discretized using continuous piecewise linear finite elements while a variational discretization concept is applied for the control. To perform the adaptive mesh refinements cycle we derive local error estimators which extend the goal-oriented error approach to our setting. The performance of the overall adaptive solver is assessed by numerical examples.
Rectangular Lattice Boltzmann Equation for Gaseous Microscale Flow
Authors: Ren Junjie , Guo Ping , Guo Zhaoli 
Published: January 2016

AbstractThe lattice Boltzmann equation (LBE) is considered as a promising approach for simulating flows of liquid and gas. Most of LBE studies have been devoted to regular square LBE and few works have focused on the rectangular LBE in the simulation of gaseous microscale flows. In fact, the rectangular LBE, as an alternative and efficient method, has some advantages over the square LBE in simulating flows with certain computational domains of large aspect ratio (e.g., long micro channels). Therefore, in this paper we expand the application scopes of the rectangular LBE to gaseous microscale flow. The kinetic boundary conditions for the rectangular LBE with a multiple-relaxation-time (MRT) collision operator, i.e., the combined bounce-back/specular-reflection (CBBSR) boundary condition and the discrete Maxwell's diffuse-reflection (DMDR) boundary condition, are studied in detail. We observe some discrete effects in both the CBBSR and DMDR boundary conditions for the rectangular LBE and present a reasonable approach to overcome these discrete effects in the two boundary conditions. It is found that the DMDR boundary condition for the square MRT-LBE can not realize the real fully diffusive boundary condition, while the DMDR boundary condition for the rectangular MRT-LBE with the grid aspect ratio a≠1 can do it well. Some numerical tests are implemented to validate the presented theoretical analysis. In addition, the computational efficiency and relative difference between the rectangular LBE and the square LBE are analyzed in detail. The rectangular LBE is found to be an efficient method for simulating the gaseous microscale flows in domains with large aspect ratios.
A Numerical Method on Eulerian Grids for Two-Phase Compressible Flow
Authors: Guo Yonghui , Li Ruo , Yao Chengbao 
Published: January 2016

AbstractWe develop a numerical method to simulate a two-phase compressible flow with sharp phase interface on Eulerian grids. The scheme makes use of a levelset to depict the phase interface numerically. The overall scheme is basically a finite volume scheme. By approximately solving a two-phase Riemann problem on the phase interface, the normal phase interface velocity and the pressure are obtained, which is used to update the phase interface and calculate the numerical flux between the flows of two different phases. We adopt an aggregation algorithm to build cell patches around the phase interface to remove the numerical instability due to the breakdown of the CFL constraint by the cell fragments given by the phase interface depicted using the levelset function. The proposed scheme can handle problems with tangential sliping on the phase interface, topological change of the phase interface and extreme contrast in material parameters in a natural way. Though the perfect conservation of the mass, momentum and energy in global is not achieved, it can be quantitatively identified in what extent the global conservation is spoiled. Some numerical examples are presented to validate the numerical method developed.
Submatrix Constrained Inverse Eigenvalue Problem involving Generalised Centrohermitian Matrices in Vibrating Structural Model Correction
Authors: Xu Wei-Ru , Chen Guo-Liang 
Published: January 2016

AbstractGeneralised centrohermitian and skew-centrohermitian matrices arise in a variety of applications in different fields. Based on the vibrating structure equationwhereM, D, G, Kare given matrices with appropriate sizes andxis a column vector, we design a new vibrating structure mode. This mode can be discretised as the left and right inverse eigenvalue problem of a certain structured matrix. When the structured matrix is generalised centrohermitian, we discuss its left and right inverse eigenvalue problem with a submatrix constraint, and then get necessary and sufficient conditions such that the problem is solvable. A general representation of the solutions is presented, and an analytical expression for the solution of the optimal approximation problem in the Frobenius norm is obtained. Finally, the corresponding algorithm to compute the unique optimal approximate solution is presented, and we provide an illustrative numerical example.

Comparative life cycle assessment (LCA) of pork using different protein sources in pig feed

Published: January 2016

Abstract. Feed production is the main contributor to a subset of environmental impacts of pork production. In this context, this study is concerned with the substitution of soy products in pig diets in order to reduce these impacts. The aim of this study was to assess three alternative diets in gestating and lactating sows as well as growing and finishing pigs in order to reduce the amount of soy products used as ingredients. In the three alternative scenarios soy proteins were compensated for by either using a combination of different feedstuffs (e.g. rapeseed meal, fava beans, and synthetic amino acids) (LOW), maximising the use of legumes (mainly fava beans) (LEG) and increasing the amount of synthetic amino acids (AA). These alternative scenarios were compared with standard diets (ST) and formulated in order to reduce the crude-protein content of the diet while maintaining the same performance of the pigs. Each of the resulting 16 diets was then assessed with respect to global warming, eutrophication, acidification, and land use, both when accounting and not accounting for emissions due to land use change. The analysis per kilogram of feed showed that the ST diets performed best with regard to global warming, eutrophication, and acidification. When emissions from land use and land use change were added, ST and AA diets appeared to have the least impact. In contrast, the assessment of scenarios per kilogram of pork highlighted that the AA scenario contributed the least in all impact categories. In conclusion, it is possible to partly replace soybean products by using synthetic amino acids in order to minimise the environmental impacts of the pork supply chain.

Abstract. More than a decade ago it was suggested that a cooling of stratospheric temperatures by 1 K or an increase of 1 ppmv of stratospheric water vapour could promote denitrification, the permanent removal of nitrogen species from the stratosphere by solid polar stratospheric cloud (PSC) particles. In fact, during the two Arctic winters 2009/10 and 2010/11 the strongest denitrification in the recent decade was observed. Sensitivity studies along air parcel trajectories are performed to test how a future stratospheric water vapour (H2O) increase of 1 ppmv or a temperature decrease of 1 K would affect PSC formation. We perform our study based on measurements made during the Arctic winter 2010/11. Air parcel trajectories were calculated 6 days backward in time based on PSCs detected by CALIPSO (Cloud Aerosol Lidar and Infrared Pathfinder satellite observations). The sensitivity study was performed on single trajectories as well as on a trajectory ensemble. The sensitivity study shows a clear prolongation of the potential for PSC formation and PSC existence when the temperature in the stratosphere is decreased by 1 K and water vapour is increased by 1 ppmv. Based on 15 years of satellite measurements (2000–2014) from UARS/HALOE, Envisat/MIPAS, Odin/SMR, Aura/MLS, Envisat/SCIAMACHY and SCISAT/ACE-FTS it is further investigated if there is a decrease in temperature and/or increase of water vapour (H2O) observed in the polar regions similar to that observed at midlatitudes and in the tropics. Performing linear regression analyses we derive from the Envisat/MIPAS (2002–2012) and Aura/MLS (2004–2014) observations predominantly positive changes in the potential temperature range 350 to 1000 K. The linear changes in water vapour derived from Envisat/MIPAS observations are largely insignificant, while those from Aura/MLS are mostly significant. For the temperature neither of the two instruments indicate any significant changes. Given the strong inter-annual variation observed in water vapour and particular temperature the severe denitrification observed in 2010/11 cannot be directly related to any changes in water vapour and temperature since the millennium. However, the observations indicate a clear correlation between cold winters and enhanced water vapour mixing ratios. This indicates a connection between dynamical and radiative processes that govern water vapour and temperature in the Arctic lower stratosphere.
Radiative and thermodynamic responses to aerosol extinction profiles during the pre-monsoon month over South Asia

Published: January 2016

Abstract. Aerosol radiative effects and thermodynamic responses over South Asia are examined with the Weather Research and Forecasting model coupled with Chemistry (WRF-Chem) for March 2012. Model results of aerosol optical depths (AODs) and extinction profiles are analyzed and compared to satellite retrievals and two ground-based lidars located in northern India. The WRF-Chem model is found to heavily underestimate the AOD during the simulated pre-monsoon month and about 83 % of the model's low bias is due to aerosol extinctions below  ∼  2 km. Doubling the calculated aerosol extinctions below 850 hPa generates much better agreement with the observed AOD and extinction profiles averaged over South Asia. To separate the effect of absorption and scattering properties, two runs were conducted: in one run (Case I), the calculated scattering and absorption coefficients were increased proportionally, while in the second run (Case II) only the calculated aerosol scattering coefficient was increased. With the same AOD and extinction profiles, the two runs produce significantly different radiative effects over land and oceans. On the regional mean basis, Case I generates 48 % more heating in the atmosphere and 21 % more dimming at the surface than Case II. Case I also produces stronger cooling responses over the land from the longwave radiation adjustment and boundary layer mixing. These rapid adjustments offset the stronger radiative heating in Case I and lead to an overall lower-troposphere cooling up to −0.7 K day−1, which is smaller than that in Case II. Over the ocean, direct radiative effects dominate the heating rate changes in the lower atmosphere lacking such surface and lower atmosphere adjustments due to fixed sea surface temperature, and the strongest atmospheric warming is obtained in Case I. Consequently, atmospheric dynamics (boundary layer heights and meridional circulation) and thermodynamic processes (water vapor and cloudiness) are shown to respond differently between Case I and Case II, underlining the importance of determining the exact portion of scattering or absorbing aerosols that lead to the underestimation of aerosol optical depth in the model. In addition, the model results suggest that both the direct radiative effect and rapid thermodynamic responses need to be quantified for understanding aerosol radiative impacts.
