BAPNE as A Mediation and Conflict Resolution tool in Education Methodological Introduction
The main objective of this research article is to propose a new model for educational mediation, based on the use of a fourth involved party (the whole group within a classroom) whom, with the use of Bapne methodology through music, rhythm and body percussion, becomes a necessary tool in conflict resolution. Our aim is to give new mediation-specific tools and strategies to university students of pre-school, primary and secondary education, in order for them to use them when they perform as teachers. We will look at and analyse why the principal studies and theorists on the topic, such as Sara Cobb, William Ury and Baruch and Folger propose 3 parties, exclusively, for conflict resolution: 2 confronted parties and a mediator. We will then justify our proposal for a fourth party: the group, the community. The strategy to be carried out is the reiterated practise of BAPNE activities within the classroom and with those parties in conflict in order to generate reengagement, satisfaction, empathy, inclusion work and coexistence with a double aim: to tackle existing conflicts and to prevent those that might arise in the future
Robustness Analysis of Eigenstructure Assignment Controllers on Rigid-Flexible Satellites
Flexible spacecraft with attached solar panels may exhibit undesired vibrations and structural deformations. These types of vehicles show an intrinsic coupling of the elements of the structure. The attitude maneuvers performed by flexible spacecraft may cause non-desired deflections of attached flexible elements. Any attitude and orbit control system generally solves these problems using filters that are designed to attenuate the relative deflections of flexible appendages. In this paper, we propose a method for designing attitude static controllers using an eigenstructure assignment (EA) method. A set of requirements were specified from our understanding of the system modes in an open loop. Exhaustive theoretical and numerical simulations were performed on special cases to verify the controller design procedure. In the design of the controller, we considered all of the aspects that relate to the eigenstructure assignment. The primary objective of this paper is to demonstrate the feasibility of obtaining a high degree of decoupling for some selected modes via the application of an EA method. Finally a robustness analysis is perform to the system together with the designed controller by means of a mu-analysi

Software tool for simulation of aircraft trajectories
New concepts in air navigation have been introduced recently. Among others, are the concepts of trajectory optimization, 4D trajectories, RBT (Reference Business Trajectory), TBO (trajectory based operations), CDA (Continuous Descent Approach) and ACDA (Advanced CDA), conflict resolution, arrival time (AMAN), introduction of new aircraft (UAVs, UASs) in air space, etc. Although some of these concepts are new, the future Air Traffic Management will maintain the four ATM key performance areas such as Safety, Capacity, Efficiency, and Environmental impact. So much, the performance of the ATM system is directly related to the accuracy with which the future evolution of the traffic can be predicted. In this sense, future air traffic management will require a variety of support tools to provide suitable help to users and engineers involved in the air space management. Most of these tools are based on an appropriate trajectory prediction module as main component. Therefore, the purposes of these tools are related with testing and evaluation of any air navigation concept before they become fully operative. The aim of this paper is to provide an overview to the design of a software tool useful to estimate aircraft trajectories adapted to air navigation concepts. Other usage of the tool, like controller design, vertical navigation assessment, procedures validation and hardware and software in the loop are available in the software tool. The paper will show the process followed to design the tool, the software modules needed to perform accurately and the process followed to validate the output data
Why are you passive? : Understanding teen's sports intentions by QCA and LM
Physical inactivity is one of the most critical issues in our society. Several studies have pointed that during adolescence Physical Activity levels decline the most, becoming a critical period in the acquisition of active lifelong habits. This study aims an understanding of the variables that predict the intention of being physically active (IPA) in high school students after completing their education, comparing two different methodologies: Lineal Models (LM) and Comparative Qualitative Analysis (QCA). No research has combined these methodologies before to see the intention of being physically active in high school. 307 adolescents from 14 to 19 years old (Mean=15.64 ±1.12), 55.5% boys, participated in the research. To get the results, a Hierarchical Regression Model with two steps; 1: Attitude toward the Behaviour (ATB), Perceived Behavioural Control (PBC) and Subjective Norm (SN); 2: Athletic Identity (AI) and Physical Self-concept (PSC) and a Fuzzy-set Qualitative Comparative Analysis (fsQCA) were performed. The first step explain 26% of IPA while the addition on step to explains 65% 2 = .38), AI is the most influential aspect (β=.74). Considering the fsQCA results, none of the conditions is crucial condition of IPA, although low levels of PBC seem to be the most important condition of not having IPA. Regarding sufficiency, five combinations explain 70% of IPA. The three most important combinations where having high levels of PSC and PBC; high levels of AI and ATB; and high levels PBC and ATB (explaining 45%; 60% and 43% respectively of IPA). In general QCA is more explanatory than LM.La inactividad física es uno de los temas más críticos en nuestra sociedad. Diferentes estudios han señalado que durante la adolescencia los niveles de Actividad Física disminuyen, convirtiéndose en un período crítico en la adquisición de hábitos activos que perduren a lo largo de toda la vida. Es por ello que este estudio tiene como objetivo comprender las variables que predicen la intención de ser físicamente activo (IFA) en estudiantes de secundaria después de completar su educación, comparando dos metodologías diferentes: Modelos Lineales (ML) y Análisis Cualitativo Comparativo (ACC). Ninguna investigación ha combinado anteriormente estas metodologías para conocer la intención de ser físicamente activo en la escuela secundaria. 307 adolescentes de 14 a 19 años ± 1,12), 55,5% varones, participaron en la investigación. Para obtener los resultados, se realizó un Modelo de Regresión Jerárquica con dos pasos 1: Actitud hacia el Comportamiento (AHC), Control del Comportamiento Percibido (CCC) y Norma Subjetiva (NS); 2: Se añadió la identidad atlética (IA) y el autoconcepto físico (AF), y un análisis comparativo cualitativo de Fuzzy-set (fsQCA). El primer paso explica el 26% de IFA mientras que la adición en el siguiente paso explica el 65% (R2 = .38), siendo IA el aspecto más influyente (β = .74). Considerando los resultados de la fsQCA, ninguna de las condiciones es condición necesaria de las IFA, aunque los niveles bajos de CCC parecen ser la condición más importante de no tener IFA. En cuanto a la suficiencia, cinco combinaciones explican el 70% de las IFA. Las tres combinaciones más importantes donde tienen altos niveles de AF y CCC; altos niveles de IA y AHC; CCC y AHC (explicando un 45%, 60% y 43%, respectivamente, de IPA). En general, el ACC es más explicativo que el ML
An ethnographic approach to the concepts of health and disease in the Turkana tribe: a project to improve the health of the nomads of the Ilemi Triangle, Kenya
El objetivo de este artículo es ofrecer una aproximación a la cultura de la tribu turkana del Triángulo de Ilemi, al noroeste de Kenia, en especial al modo en el que los miembros de este grupo étnico nómada entienden y dan forma a su propio constructo de salud y enfermedad. Se basa en un estudio etnográfico llevado a cabo en julio y agosto de 2014, en el que se realizaron observación participante en 15 aldeas de la tribu turkana, entrevistas informales y entrevistas en profundidad, con la colaboración de dos traductoras de la tribu y un enfermero. Se tomaron registros escritos, de video y de audio, los que se transcribieron para su posterior análisis. Entre los principales resultados de este estudio cabe destacar que tanto el concepto de salud como el de enfermedad distan mucho del enfoque occidental que a priori traen los proyectos externos y es probable que la falta de adherencia al seguimiento terapéutico de dichos proyectos esté relacionada con el desconocimiento cultural de ambos constructos por parte del equipo profesional.This paper aims to provide a broad view of the Turkana tribe of the Ilemi Triangle in northwestern Kenya, especially regarding the way the members of this nomadic ethnic group understand and shape their own construct of health and disease. It is based in an ethnographic study carried out in July and August 2014, including participant observation of 15 villages of the Turkana tribe, formal interviews and in-depth interviews carried out with the collaboration of two translators of the tribe and a nurse. Field notes as well videos and audio records were captured and transcribed for later analysis. Among the primary results of this study, it should be highlighted that the concepts of both health and disease differ greatly from the western approach that external projects bring with them a priori and it is likely that the lack of adherence to these projects is related to the scant cultural knowledge regarding such constructs on the part of the health professionals
Sinorhizobium fredii HH103 RirA is required for oxidative stress resistance and efficient symbiosis with Soybean
Members of Rhizobiaceae contain a homologue of the iron-responsive regulatory protein RirA. In different bacteria, RirA acts as a repressor of iron uptake systems under iron-replete conditions and contributes to ameliorate cell damage during oxidative stress. In Rhizobium leguminosarum and Sinorhizobium meliloti, mutations in rirA do not impair symbiotic nitrogen fixation. In this study, a rirA mutant of broad host range S. fredii HH103 has been constructed (SVQ780) and its free-living and symbiotic phenotypes evaluated. No production of siderophores could be detected in either the wild-type or SVQ780. The rirA mutant exhibited a growth advantage under iron-deficient conditions and hypersensitivity to hydrogen peroxide in iron-rich medium. Transcription of rirA in HH103 is subject to autoregulation and inactivation of the gene upregulates fbpA, a gene putatively involved in iron transport. The S. fredii rirA mutant was able to nodulate soybean plants, but symbiotic nitrogen fixation was impaired. Nodules induced by the mutant were poorly infected compared to those induced by the wild-type. Genetic complementation reversed the mutant’s hypersensitivity to H2O2, expression of fbpA, and symbiotic deficiency in soybean plants. This is the first report that demonstrates a role for RirA in the Rhizobium-legume symbiosis.Andalucian Government Grant No. P11-CVI-7500Spanish Government Grant Nos.

The Application of Rapid Prototyping in the Design of an UAV.
Design and building of UAVs (for civil and military missions) is a field of actuation where the most important Universities, research Centers and Aeronautical designers have dedicated a lot of human effort. In recent years, a team of students and professors (at the Escuela Universitaria de Ingeniería Técnica Aeronáutica, EUITA) have been working on the design and building of an UAV for civil observation. This paper presents the highlights of this project, focussing on the role of rapid prototyping. Furthermore, this paper will present all the features and stages of this engineering project. Also, the current state of technology applied to the process will be presented together with a description of the main difficulties the project has undergone, as a global experience in engineering design and development
Expression of Musashi-1 Increases in Bone Healing
The authors of this manuscript were partially supported by Research Groups #CTS-138 and
#CTS-1028 (Junta de Andalucía, Spain). This research received no specific grant from any funding
agency in the public, commercial, or not-for-profit sectors.All experiments were performed after the approval of the
Committee on Animal Research of the University of Granada (CEEA 2014/357) and under the
European Union and Spanish regulations for ethics in animal research (EU Directive 63/2010 and
Spanish RD 53/2013) and reported following the ARRIVE guidelines.The data that support the findings of this study are available from the
corresponding author upon reasonable request.The authors would especially like to acknowledge the contribution to the
histochemical and immunohistochemical studies of Serafin Vélez García and Carmen Ruíz Guzmán,
technicians in the Department of Surgery, and María Dolores Rodriguez, in the Department of
Pathology and IBIMER of the University of Granada and Justin G. Davis for assistance with the
writing style.Musashi-1 (MSI1) is an RNA-binding protein that regulates progenitor cells in adult and developing organisms to maintain self-renewal capacities. The role of musashi-1 in the bone healing environment and its relation with other osteogenic factors is unknown. In the current study, we analyze the expression of MSI1 in an experimental model of rat femoral bone fractures. We also analyze the relation between MSI1 expression and the expression of two osteogenic markers: periostin (POSTN) and runt-related transcription factor 2 (RUNX2). We use histological, immunohistochemical, and qPCR techniques to evaluate bone healing and the expression of MSI1, POSTN, and RUNX2 over time (4, 7, and 14 days). We compare our findings with non-fractured controls. We find that in bone calluses, the number of cells expressing MSI1 and RUNX2 increase over time and the intensity of POSTN expression decreases over time. Within bone calluses, we find the presence of MSI1 expression in mesenchymal stromal cells, osteoblasts, and osteocytes but not in hypertrophic chondrocytes. After 14 days, the expression of MSI1, POSTN, and RUNX2 was significantly correlated. Thus, we conclude that musashi-1 potentially serves in the osteogenic differentiation of mesenchymal stromal cells and bone healing. Therefore, further studies are needed to determine the possibility of musashi-1 ' s role as a clinical biomarker of bone healing and therapeutic agent for bone regeneration.Junta de Andalucia

A pyrF auxotrophic mutant of Sinorhizobium fredii HH103 impaired in its symbiotic interaction with soybean and other legumes
Transposon Tn5-Mob mutagenesis allowed the selection of a Sinorhizobium fredii HH103 mutant derivative (SVQ 292) that requires the presence of uracil to grow in minimal media.
The mutated gene, pyrF, codes for an orotidine-5 ́- monophosphate decarboxylase (EC 4.1.1.23).
Mutant SVQ 292 and its parental prototrophic mutant HH103 showed similar Nod-factor and lipopolysaccharide profiles.
The symbiotic properties of mutant SVQ 292 were severely impaired with all legumes tested. Mutant SVQ 292 formed small ineffective nodules on Cajanus cajan and abnormal nodules (pseudonodules) unable to fix nitrogen on Glycine max (soybean), Macroptitlium atropurpureum, Indigofera tinctoria, and Desmodium cana-dense. It also did not induce any macroscopic response in Macrotyloma axillare roots.
The symbiotic capacity of SVQ 292 with soybean was not enhanced by the addition of uracil to the plant nutritive solution
