A founder-controlled, social wasp assemblage, and a recent severe fall in numbers
Authors: Raw Anthony
Published: July 2018

The 35 species of social wasps surveyed in an 8 ha plot in the Cabeça de Veado valley near Brasilia (1979 and 1997) averaged 17.9 species per survey. From 1/3 to 1/2 of the species disappeared between consecutive surveys and only two were present in every survey. On average, 43% of the 40 species known to inhabit the valley were recorded on each survey. This high rate of turn-over demonstrates that the wasps comprised a “founder-controlled” assemblage. On two more surveys, nine species were recorded in 2010 and ten in 2015; numbers which reflect recent reports on the global trend of losses of social wasps.
The Roles of Bees and Hoverflies in the Pollination of Jacquemontia evolvuloides (Moric.) Meisn. (Convolvulaceae) in a Semiarid Region
Authors: Da Paz Joicelene Regina Lima , Pigozzo Camila Magalhães , Gimenes Miriam
Published: July 2018

Jacquemontia species are often found in disturbed areas, and their flowers are ephemeral and very attractive to insects. We investigated the interaction between the flowers of Jacquemontia evolvuloides and its visitors, with emphasis on potential pollinators, considering morphological, temporal, and behavioral aspects, between September/2009 and August/2010 in an anthropized area in Bahia State, Northeastern Brazil. Jacquemontia evolvuloides flowers are diurnal, ephemeral (approximately five to six hours duration), are present throughout the year, and offer nectar and pollen rewards. Because of the floral morphology of J. evolvuloides insect visitors have easy access to its resources, and its pollination could be considered generalized. While J. evolvuloides flowers are visited by several insects, only small bees (Augochlora spp.) and syrphids (Toxomerus spp.) appear to play a role in pollination of flowers. Although bees have been considered efficient pollinators of that plant, the significant presence of syrphids (considered occasional pollinators but showing high frequency visitation), may indicate their role as potential pollinators, especially when bees are not abundant in the fall/winter. As such, even in pollination systems that are considered generalized (with flowers allowing easy access to various visitor groups), visitor size may be an important factor for efficient pollination, especially when associated with high visitation frequencies.

Published: July 2018

Adipokinetic hormone receptor (AKHR) was regarded as the crucial regulator of lipid consuming, but now has been renewed as a pluripotent neuropeptide G protein-coupled receptor. It has been identified in all sequenced bee genomes from the solitary to the eusocial. In the current study, we try to clarify the transitions of AKHR on lipid utilization and other potential functions from solitary to eusocial bees. The results showed that the AKHRs were divided into different groups based on their social complexity approximately. Nevertheless, the critical motifs and tertiary structures were highly conserved. As to the post-translational modifications, the eusocial possessed more phosphorylation residues and modification patterns, which might be due to the necessity of more diverse functions. These results suggest that AKHRs are highly conserved on both primary motifs and tertiary structures, but more flexible on posttranslational modifications so as to accommodate to more complicated eusocial life.

Published: July 2018

The importance of Simarouba versicolor St. Hil. fruit dispersal by the leaf-cutting ant Atta sexdens (L.) was studied in the Cerrado, Tocantins, Brazil. The trees and nests were located between a forest area and a Brachiaria decumbens Stapf pasture. Seeds were collected in October 2015 along foraging trails and on the anthill of an A. sexdens colony. Germination of three groups of seeds was tested: (1) seeds with the tegument removed by the ants; (2) seeds without tegument, cleaned manually, and (3) seeds with tegument. The germination rates for the three treatments were similar; however, it was verified that the seeds cleaned by ants germinated faster. In addition, it was verified that the ants dispersed the seeds by at least 20 meters in the study area. Simarouba versicolor is a plant studied for its insecticidal properties, and this is the first study to our knowledge reporting its dispersal by ants.

Published: July 2018

Ants often colonize twigs in the leaf litter, but some species use this resource more frequently than others. We analyzed the composition of the community and the diameter of colonized twigs to test if any species had a size preference. Samples were collected in different vegetation habitats (urban parks, eucalyptus plantations and native forests). In each site, all twigs with an ant colony in six 16-m2 plots were collected and measured, and the ants occupying them were identified. For the analyses, we only included species recorded in 10 or more twigs; these species were considered “common inhabitants” of the twigs (approximately 19.7% of the fauna analyzed). Our results indicate that the community is richer and uses a larger number of twigs of different diameters in the native forest. In addition, some species colonized twigs of similar sizes in different vegetation habitats, suggesting possible selection by ants.

Published: July 2018

In general, termite foraging can be affected by physical and chemical factors linked to food. This study investigated if the wood length of Eucalyptus grandis W. Hill ex Maiden, as a food resource, influences the behavior of foraging events of Nasutitermes corniger (Motschulsky). Nests with mature and active colonies were collected in the field and transferred to glass cubes connected to a test arena under laboratory conditions. Wooden blocks of E. grandis, with a 2.5 x 2.0 cm rectangular cross section, were offered to termites in three different lengths: 5, 10 and 15 cm. Each test was repeated with 20 nests and lasted 60 minutes, when the following behavioral events and their duration were observed: initial exploration, initial recruitment and mass recruitment. At the end of each test, the quantities of termites (total, workers and soldiers) and gnawing workers were determined. The results show that longer blocks favored a higher occurrence of exploration and initial recruitment. However, the highest mass recruitment occurred with the 10 cm blocks. The length of the wood influenced the total number of termites recruited and gnawing workers; both were highest for the 10 cm blocks. There was no significant difference in relation to exploration time of the blocks and number of workers and soldiers recruited. Therefore, we conclude that wood length is a factor that can affect N. corniger foraging.
Pequeños espacios, grandes proyectos. Los interiores comerciales en España: de la modernidad a la globalización
Authors: Cano Redondo Armando
Published: July 2018

El zócalo de la ciudad es la imagen de la ciudad a la altura de los ojos, la que el ciudadano puede tocar y reconocer como suya. El contacto del edificio con la calle es la franja de pocos metros con la que el peatón interactúa, la cual queda definida, en gran medida, por la actividad comercial.Desde una condición de valla publicitaria, las tiendas se convierten en una herramienta para la difusión de las novedades, no solo comerciales, sino también de la modernidad y la vanguardia artística, arquitectónica y constructiva. Un campo de ensayo que no se limita a la imagen de la fachada, sino que, en su naturaleza exhibicionista, establece un diálogo productivo entre el exterior y el interior.Este texto, adaptación del leído en el acto de defensa de esta tesis doctoral, recorre la evolución y las herramientas proyectuales utilizadas en la definición de los locales comerciales en España en el medio siglo comprendido entre el alumbramiento del Movimiento Moderno y el cambio de paradigma económico y social que supuso la crisis mundial de finales de los 70. Un recorrido realizado a través de tres miradas: la primera focalizada sobre la calle comercial –un exterior social, la escala urbana–, la segunda depositada en la fachada comercial –una frontera gráfica, la escala arquitectónica–, y la tercera, y más extensa, puesta sobre los elementos arquitectónicos que componen el interior comercial –un nuevo exterior, la escala del detalle–.

Authors: Abdella M. H. , Musa A. E. , Ali S. B.
Published: July 2018

The retanning process is a very important step in leather manufacturing because it overcomes some of the disadvantages of chrome tannage and it can contributes to further stabilization of collagen fibers and good handle of leather, such as fullness, softness, elasticity and so on. In order to meet customers’ requirements, a wide variety of retanning agents are used in retanning process viz. vegetable tan and phenolic synthetic/organic tanning materials. Sunt bark, widely distributed in Sudan, has been evaluated for its utilization in the retanning of the leathers. In the present investigation, sunt bark powder has been used for the retanning of wet blue leathers. The effectiveness sunt bark in retanning of wet blue leathers has been compared with wattle retanning. The organoleptic properties of the leathers viz. softness, fullness, grain smoothness, grain tightness (break), general appearance, uniformity of dyeing of sunt bark retanned leather have been evaluated in comparison with wattle retanned leathers. Sunt retanning resulted in leathers with good grain tightness. Physical strength characteristic and shrinkage temperature were noted. Dyeing characteristics of sunt retanned leathers have been found to be better than wattle retanned leathers.
Technical and Economical Assessment of using Static Compensators for Improving Power Quality in Distribution Power Systems
Authors: Tajik Reza
Published: July 2018

Nowadays, various issues regarding the power quality have been widely considered. Regarding to the progress made in power electronics in recent years, the best way to improve the reliability of reducing voltage deviations, reducing losses, and generally providing high quality to consumers is to use custom power devices (CPDs). Series, parallel, or hybrid devices come from a subset of CPDs such as a dynamic voltage restorer, distribution static compensator, and unified power quality conditioner. In this work, the purpose of place these devices are to achieve various goals of improving power quality and reducing system costs. To achieve these goals, at first, the problem of single-objective optimization for each of the objective functions was solved separately. After determining the optimal value of each of the objective functions, the fuzzy membership functions for each of the objective functions were suitably optimized for each objective function. A mixed integer genetic algorithm was used to find the optimal answer to this multi-objective problem. The simulation results show that the proposed algorithm has worked well to find the optimal solution. The results of multi-objective planning proposed in this study show that with proper planning, it can be done at a low cost and even with a relatively high profit to cost and with the proper place of CPDs, to solve issues related to power quality issues in distribution networks.

In this project work the design and construction of a model of automatic braking system for vehicles in hill station is to be developed. The mechanism has been developed to stop the vehicle from rolling back word when the vehicle is
moving in the hill roads. This construction made of two phases in a first deigns of ratchet and pawl mechanism,
frame, shaft, etc. is done and in second sensor selection and interference is done. Ratchet and pawl mechanism has
been fabricated and assembly with sensor interface is tested. The proposed mechanism is to reverse break using
ratchet gear. By reverse locking the differential is disengaged from the axle. Thus the power is directly transmitted to
the axle and hence to the wheels. This will considerably reduce the power loss in some occasions when unwanted loss
is happening due to the transmission if power from the shaft to the ratchet gear and then to the axle and hence to the
wheels. So in mechanism the unwanted power loss in the due course of transmission through the gear wheel is
reduced.
Projecting the Multiracial University
Authors: Fukumori Ryan
Published: July 2018

During the 1960s, the University of California, Los Angeles (UCLA) hosted research surveys focused on two of Southern California’s largest communities of color: the Japanese American Research Project (JARP, 1962–1970) and the Mexican American Study Project (MASP, 1964–1968). While conceived in separate sectors of the university’s research apparatus, JARP and MASP together exemplify UCLA’s gradual institutionalization of racial diversity over the course of the decade. In the years before UCLA could claim a critical mass of nonwhite scholars and students, these projects inaugurated campus-community relations with local civil rights organizations as both collaborators and critics. Together, JARP and MASP demonstrate that the multiracial integration of California’s higher education system was a prolonged process, first requiring the state’s predominantly white public universities to develop institutional vocabularies of racial difference where none existed prior.
Aggressive and malignant pituitary tumours: state-of-the-art
Authors: Dworakowska Dorota , Grossman Ashley B
Published: July 2018

Pituitary adenomas are unique in multiple ways. They are rarely malignant in terms of metastases; yet, they may be aggressive. Their cancerous potential is defined in a classic oncological way by the ability to metastasise, and therefore, it has been crucial to differentiate this process from aggressive behaviour, characterised as a particularly invasive and/or recurrent behaviour and resistance to common modalities of therapy. Recently, however, important changes have been introduced to the diagnosis and management of aggressive and malignant pituitary tumours including the 4th edition of the World Health Organization (WHO) classification for endocrine tumours (2017) as well as ESE Clinical Guidelines (2018), although an attempt to establish predictive and/or prognostic markers of clinical aggressiveness remains difficult. In this review, we focus on a group of pituitary tumours causing significant problems in clinical practice and requiring multidisciplinary input. We summarise updates in definitions of tumour invasiveness, aggressiveness and malignant transformation, as well as histological classification, and emphasise the new considerations regarding aggressive and malignant potential and its relationship to therapeutic strategies.

Invarianza por sexo y distribución del Índice de Satisfacción Sexual reducido en una muestra mexicana de rutas aleatorias
Authors: Moral de la Rubia José
Published: July 2018

Objetivo: El Índice de Satisfacción Sexual de Hudson constituye una medición unidimensional de la satisfacción sexual empleada en investigación y clínica. En México, se ha propuesto una forma reducida a 10 ítems del ISS (ISS-10). Los objetivos del estudio fueron aportar nuevas evidencias de validez cruzada (entre mujeres y hombres) y convergente del ISS-10, describir su distribución y estudiar su relación con seis variables sociodemográficas. Método: Se realizó una investigación instrumental. A 807 personas casadas o en unión libre de Monterrey, México, se les aplicó el ISS, la Escala de Valoración de la Relación (RAS), la Escala de Engrandecimiento Marital (MAS) y otras cuatro escalas entre enero y mayo de 2014, mediante un muestreo de rutas aleatorias. Se aplicó análisis factorial confirmatorio multigrupo. Resultados: El modelo de un factor con 10 indicadores mostró invarianza entre mujeres y hombres. Las puntuaciones del ISS-10 no siguieron una distribución normal. En la muestra total, la correlación del ISS-10 con la satisfacción con la relación (RAS) fue muy alta (rS = .71) y con el engrandecimiento marital (MAS) fue alta (rS = .56). La edad, los años de casados o en unión libre y la escolaridad presentaron correlaciones bajas con el ISS-10 (rS de .13 a .27). El sexo y el estado civil fueron independientes del ISS-10. Conclusión: El Índice de Satisfacción Sexual, como una medición unidimensional de la satisfacción sexual reducida a 10 indicadores, presenta evidencias de validez; es independiente de ser hombre o mujer, y puede ser baremado usando puntuaciones de percentil.

Diversidad Sorda: educación y sensibilidad intercultural en una escuela especial de Santiago de Chile
Authors: Morales Acosta Gina Viviana , Morales Navarro Mario
Published: July 2018

La finalidad del presente artículo consiste en describir los componentes de educación y sensibilidad intercultural que se evidencian en la práctica docente con el estudiante sordo en la escuela especial. Se destaca el principio sobre estudiantes sordos estipulado en el documento de la UNESCO (2006) en pro de los aprendizajes en educación, que debe asumir los deberes y derechos inherentes al sujeto sordo en su particularidad lingüística: “La educación intercultural respeta la identidad cultural del educando impartiendo a todos una educación de calidad que se adecúe y adapte a su cultura”. De acuerdo con ello, los principios de educación intercultural deben construirse considerando que: I) Se respete la identidad cultural del educando impartiendo a todos [as] una educación de calidad que se adecúe y se adapte a su cultura; II) Se enseñe a cada educando los conocimientos, las actitudes y las competencias culturales necesarias para que pueda participar plena y activamente en la sociedad; III) La elaboración de programas propios de estudio. Esto exige que la institución promueva el acercamiento a la asociación y a la comunidad sorda, para que los estudiantes la conozcan e interactúen en etapas tempranas y así propendan hacia la negociación simétrica de las culturas para reconocer a un Otro diverso en las prácticas docentes del aula.

Measurement and computation of kinetic energy of simulated rainfall in comparison with natural rainfall.
Authors: Jan Petrů , Jana Kalibová
Published: July 2018

Rainfall characteristics such as total amount and rainfall intensity (I) are important inputs in calculating the kinetic energy (KE) of rainfall. Although KE is a crucial indicator of the raindrop potential to disrupt soil aggregates, it is not a routinely measured meteorological parameter. Therefore, KE is derived from easily accessible variables, such as I, in empirical laws. The present study examines whether the equations which had been derived to calculate KE of natural rainfall are suitable for the calculation of KE of simulated rainfall. During the experiment presented in this paper, the measurement of rainfall characteristics was carried out under laboratory conditions using a rainfall simulator. In total, 90 measurements were performed and evaluated to describe the rainfall intensity, drop size distribution and velocity of rain drops using the Thies laser disdrometer. The duration of each measurement of rainfall event was 5 minutes. Drop size and fall velocity were used to calculate KE and to derive a new equation of time-specific kinetic energy (KEtime – I). When comparing the newly derived equation for KE of simulated rainfall with the six most commonly used equations for KEtime – I of natural rainfall, KE of simulated rainfall was discovered to be underestimated. The higher the rainfall intensity, the higher the rate of underestimation. KE of natural rainfall derived from theoretical equations exceeded KE of simulated rainfall by 53–83% for I = 30 mm/h and by 119–275% for I = 60 mm/h. The underestimation of KE of simulated rainfall is probably caused by smaller drops formed by the rainfall simulator at higher intensities (94% of all drops were smaller than 1 mm), which is not typical of natural rainfall.

The Effect of Online Feedback Types on Foreign Language Writing
Authors: Liu Xiaoling , Zhou Changping
Published: July 2018

In this study a comparison is made concerning the effect of online teacher feedback and online peer feedback on foreign language writing and the learners’ attitudes toward online feedbacks. To address the issues, an experiment is carried out between two university classes, who received online teacher feedback and online teacher feedback respectively. Based on the analysis, the major findings are obtained as follows. Firstly, the writing in each group has been improved significantly after the application of online feedback. However, no significant difference is shown between groups A and B. Secondly, students in both groups can incorporate feedback into their revisions, though there exist some differences in the number of successful revisions and kinds of revisions between the two groups. Finally, both online teacher feedback and online peer feedback are very well received by most students respectively. The research findings indicate that online feedback should be adopted in foreign language writing teaching.

The current Pinyin Romanization of Chinese book and journal titles is rich in examples of inconsistencies, and this problem has much more been identified than examined. The current paper traces the problem back to the guiding documents, analyzes their inborn problem. It is argued that the currently dominant practice of aggregating syllables is the source of the inconsistencies, and it results from ambiguous wordings and misconception of “ci” as the basic unit in the guiding documents. Based on this analysis, a practice of Romanizing Chinese on the basis of “zi” is put forward, and the underlying rationale analyzed. The purpose is to contribute to the solution of the issue of inconsistency and offer an approach to standardizing the practice of Pinyin Romanization of Chinese book and journal titles.
Content and Language Integrated Learning for First and Second Year University Students - Aspirations, Challenges and Solutions
Authors: Brooke Mark
Published: July 2018

This paper offers an overview of two modules from the Centre for English Language Communication, National University of Singapore. These belong to a programme entitled the Ideas and Exposition Modules (IEM) and they pertain to a content and language integrated learning (CLIL) approach. The courses and some of the main learning objectives are explained. These are critical thinking abilities; research skills; and academic study skills. It is surmised that these are useful for all students independent of their academic discipline. The challenges that the lecturer and students face during the courses are also presented. These challenges often arise because students are from different educational cultures and academic disciplines, and as a result, classes tend to be comprised of students with mixed interests, English language levels and academic research and writing experience. Students also tend to vary in their abilities to think critically and work independently. The first section in this paper looks at the educational context of the IEM courses; the second, presents the core learning outcomes aspired to; the third, examines the challenges faced and how these are met by the tutor and students taking the courses. The final section offers a brief overview of the paper and considers the future for this genre of course, particularly how students benefit from a more student-centered, individualized educational practice today.

The present study used a Hybrid Problem-Based Learning (H-PBL) approach for teaching a Speaking Course to the First-Year students of the English Department at Prince Sattam Bin Abdulaziz University, Saudi Arabia. Previous research has proved the currently inappropriate teaching approaches and the lack of motivation to be the most significant reasons for EFL students' poor speaking proficiency. The lack of motivation is due to the traditional, rigid and tedious teaching techniques adopted in speaking classrooms and partly due to the standardized curriculum of the speaking course where there is no scope for instructors to change their teaching approach or introduce new ideas in the curriculum. The H-PBL approach has been proved to be an effective model for teaching language skills; however, the existing literature still lacks an actual action plan or a methodology to introduce this approach as a pedagogical remedy for motivating EFL students and improving their speaking proficiency. The study addressed this gap by recommending the use of H-PBL approach in EFL speaking classes. The study used a pre-post speaking proficiency test, a students' motivation questionnaire, interviews and observation sheets as data collection tools. Results revealed that the H-PBL approach has a positive effect on improving the students' speaking proficiency, students' motivation significantly increased and, eventually, students tended to be more self-directed and independent. Instructors also applauded the use of H-PBL approach but recommended adapting the curriculum and the teaching strategies to support this approach.
L’objet comme expression de soi: exemple d’un atelier artistique d’expression plurilingue en Guadeloupe
Authors: BEAUBRUN Frédéric , CANDAU Olivier-Serge
Published: July 2018

RÉSUMÉ. La contribution présentée ici vise à rendre compte d’une expérimentation originale, associant apprentissage du français et création artistique, à destination d’un public d’apprenants allophones inscrits dans un centre de formation en Guadeloupe. Cette recherche expérimentale a vocation à montrer dans quelle mesure le détour artistique est susceptible de mobiliser le déjà-là culturel, linguistique et identitaire de l’apprenant. L’action de formation menée est l’occasion de découvrir un certain nombre d’objets du quotidien dont les usages (par leur fréquence, la finalité attribuée, ou la charge symbolique attribuée) diffèrent d’une culture à une autre. Chacun des apprenants est invité à interroger ses pairs sur le rapport entretenu par les autres à cet objet, en ayant soin de comparer l’usage qu’il en avait avant son arrivée en Guadeloupe, et celui qu’il en a depuis. Nous ferons ici l’hypothèse principale que la création artistique favorise une mobilisation forte de l’identité sociolinguistique de l’apprenant.  Mots-clés: Didactique du plurilinguisme, détours artistiques, français langue d’intégration, sociobiographie. ABSTRACT. This study attempts to investigate how far artistic diversion can mobilize learners’ cultural, linguistic and identity-related resources. The study is based on a French language learning session with artistic creativity for allophone migrant learners at a training centre in Guadeloupe. The aim of the activity is for migrant learners to integrate French language norms through guided reformulation work, involving exploring some everyday objects whose usage (whether frequency, ultimate purpose or symbolic meaning) differs between cultures. Learners ask their peers about their relationship with the object ; care is taken to compare their usage both before and after their arrival in Guadeloupe. The research is based on corpora consisting of interactions between allophone migrant learners positioning their point of view by bringing into play a collection of language resources in order to produce the required decisions and responses. The data obtained  aims to demonstrate the degree to which artistic diversion can mobilize learners’ cultural, linguistic and identity-related resources. The analysis shows that artistic creation is a strong motivator for learners’ sociolinguistic identity. Keywords: Plurilingual didactics, artistic diversion, French language integration, French as an integration language, sociobiography.
Outils didactiques, vecteurs d’interactions dans la classe de FLE en Corée du Sud
Authors: KANG Shin-Tae
Published: July 2018

RÉSUMÉ. Les apprenants de cours de langues hésitent souvent à prendre la parole en classe. Cet article vise à étudier comment les enseignants de FLE utilisent des supports pédagogiques variés dans leurs cours de conversation, et comment ces outils didactiques rendent les interactions plus vivantes et intéressantes pour les apprenants. La méthode de l’analyse conversationnelle sera appliquée à un corpus de données enregistrées authentiques et naturelles : des cours de FLE délivrés par des enseignants français à des apprenants coréens dans l’enseignement supérieur en Corée du Sud. Les données vidéo et les transcriptions seront analysées sous l’angle de la méthode empirico-inductive afin de décrire les zones d’interaction générées par chacun des outils didactiques employés dans le corpus. Il sera établit que ces zones d’interaction peuvent focaliser le regard et l’attention des apprenants dans des relations « émetteur-récepteur » entre enseignants et apprenants variant au gré des nombreux ateliers proposés. Mots-clés: apprenant coréen, FLE, interaction, outils didactique, salle de classe. ABSTRACT. Language learners are often reluctant to speak in class. This article aims to study how FFL teachers use a variety of teaching aids in their conversation classes, and how these didactic tools make interactions more lively and interesting for learners. The conversational analysis method will be applied to a corpus of authentic and natural recorded data: FFL courses delivered by French teachers to Korean learners in higher education in South Korea. The video data and transcriptions will be analyzed from the angle of the empirico-inductive method in order to describe the interaction zones generated by each of the didactic tools used in the corpus. It will be established that these interaction zones can focus the look and attention of learners in "transmitter-receiver" relations between teachers and learners, varying with the many workshops offered. Keywords: Korean learner, FFL, interaction, didactic tools, classroom.

La convivencia escolar. Un reto del siglo XXI
Authors: Penalva López Antonia
Published: July 2018

La convivencia escolar es uno de los aspectos que más preocupa al sistema educativo debido al incremento de situaciones que alteran el clima escolar. Estos hechos han suscitado a la sensibilización de la comunidad científico-educativa y han despertado en ella la necesidad de profundizar en este concepto lo que supone para el buen funcionamiento del sistema educativo y en la consecución de los logros del alumnado. De ahí, la necesidad de centrar este trabajo en conocer cuál es la situación en la que se encuentra la convivencia en los centros educativos de Educación Primaria y Secundaria de Cieza, Murcia. Concretamente se trata de conocer desde la perspectiva del profesorado de Educación Primaria y secundaria de todos los centros de Cieza, todas aquellas situaciones que se dan con más frecuencia en los centros educativos y que deterioran el clima institucional, los factores que lo provocan y las consecuencias que de ellos se derivan. Para ello, se elaboró un cuestionario destinado al profesorado, compuesto por 4 dimensiones, de carácter cuantitativo y que recoge una cuestión abierta en cada dimensión. Entre los resultados cabe destacar que en los centros se producen algunas situaciones que afectan positivamente al estado de la convivencia escolar y otras de manera negativa. Igualmente, los docentes reconocen la existencia de factores familiares, sociales y personales que poseen gran influencia en la aparición de conflictos en el contexto educativo, lo que deteriora la convivencia y se ve traducido en consecuencias negativas para los implicados y para el sistema educativo en general.
La estimulación auditiva a través de la música en el desarrollo del lenguaje en Educación Infantil
Authors: López Casanova Maria Belén , Nadal García Icíar
Published: July 2018

En el presente artículo se muestra una recopilación teórica sobre estudios que contemplan los efectos de la estimulación auditiva, a través de la música en el desarrollo del lenguaje. Se tiene en cuenta el desarrollo auditivo en los primeros años de vida, los modos de audición según las perspectivas psicológica, pedagógica y de algunos compositores que han realizado incursiones en la enseñanza de la música así como la educación musical y el desarrollo del lenguaje, estableciendo sus relaciones. Además, se presenta un estudio realizado con los maestros del colegio público Foro Romano de Cuarte de Huerva, Zaragoza. El propósito del estudio consistió en conocer la realidad de la práctica escolar llevada a cabo por los maestros sobre la incidencia de la  percepción y estimulación auditiva en el aula de Educación Infantil. Los resultados demostraron que los maestros no se sienten preparados para trabajar la audición desde una perspectiva musical, debido a un importante desconocimiento de algunos aspectos musicales como los relacionados con los parámetros sonoros, entre otros, por lo que  demandan una mayor preparación musical para llevar a cabo un proyecto educativo de estimulación auditiva en el aula.
