Published: October 2017

In NOD mice and also likely humans, B lymphocytes play an important role as APC-expanding autoreactive T cell responses ultimately causing type 1 diabetes (T1D). Currently, humans at high future T1D risk can only be identified at late prodromal stages of disease indicated by markers such as insulin autoantibodies. When commenced in already insulin autoantibody+ NOD mice, continuous BAFFR-Fc treatment alone or in combination with anti-CD20 (designated combo therapy) inhibited T1D development. Despite eliciting broader B lymphocyte depletion, continuous combo therapy afforded no greater T1D protection than did BAFFR-Fc alone. As previously observed, late disease stage–initiated anti-CD20 monotherapy did not inhibit T1D, and in this study was additionally found to be associated with development of drug-blocking Abs. Promisingly, NOD mice given transient late disease stage BAFFR-Fc monotherapy were rendered T1D resistant. However, combo treatment abrogated the protective effect of transient BAFFR-Fc monotherapy. NOD mice receiving transient BAFF blockade were characterized by an enrichment of regulatory B lymphocytes that inhibit T1D development through IL-10 production, but this population is sensitive to deletion by anti-CD20 treatment. B lymphocytes from transient BAFFR-Fc–treated mice suppressed T cell proliferation to a greater extent than did those from controls. Proportions of B lymphocytes expressing CD73, an ecto-enzyme operating in a pathway converting proinflammatory ATP to anti-inflammatory adenosine, were also temporarily increased by transient BAFFR-Fc treatment, but not anti-CD20 therapy. These collective studies indicate transient BAFFR-Fc–mediated B lymphocyte depletion elicits long-term T1D protection by enriching regulatory B lymphocytes that are deleted by anti-CD20 cotherapy.

Published: October 2017

The aim of this study was to determine whether an association exists between the performance of a sacrocolpopexy for genital prolapse and the bladder function. A case series study was performed that includes all patients who received sacrocolpopexy in a tertiary Spanish hospital. An analysis was performed to study the association of some variables and the occurrence or persistence of urinary incontinence after the surgery. Forty patients with indication of sacrocolpopexy were included. A year after sacrocolpopexy, the outcomes showed 97.3% of prolapse healing. 19.3% complained about de novo stress urinary incontinence, 33.3% recovered from it and another 66.7% remained the same. Only 10.8% asked for an anti-incontinence surgery after the sacrocolpopexy. The urethral hypermobility shows an increased risk of stress urinary incontinence after the sacrocolpopexy. Based on our results, we do not consider it necessary to perform a systematic antiincontinence procedure simultaneously with sacrocolpopexy unless a woman without urethral anti-incontinence surgical background shows a urethral hypermobility.

Authors: Wijarnpreecha K , Boonpheng B , Thongprayoon C , Jaruvongvanich V , Ungprasert P
Published: October 2017

Background/Objectives:

The possible relationship between smoking and risk of colonic diverticulosis has been suggested by recent epidemiological studies, although the results were inconsistent. This meta-analysis was conducted to summarize all available data.

Methods:

A comprehensive literature review was conducted using the MEDLINE and EMBASE databases through May 2017 to identify all studies that compared the risk of colonic diverticulosis among current and former smokers versus nonsmokers. Effect estimates from each study were extracted and combined together using the random-effect, generic inverse variance method of DerSimonian and Laird.

Results:

Of 465 potentially eligible articles, three prospective cohort studies with 130,520 participants met the eligibility criteria and were included in the meta-analysis. The risk of colonic diverticulosis in current smokers was significantly higher than nonsmokers with the pooled risks ratio of 1.46 (95% confidence interval [CI], 1.13–1.89). However, the risk of colonic diverticulosis in former smokers was not significantly higher than nonsmokers with the pooled risk ratio of 1.13 (95% CI, 0.88–1.44).

Conclusions:

A significantly increased risk of colonic diverticulosis among current smokers is demonstrated in this study.

Teaching High-Value Care in Pediatrics: A National Survey of Current Practices and Guide for Future Curriculum Development
Authors: Tchou Michael J. , Walz Alice , Burgener Elizabeth , Schroeder Alan , Blankenburg Rebecca
Published: October 2017

Background 

Health care expenditures in the United States are increasing at an unsustainable pace. There have been calls to incorporate education on resource stewardship into medical training, yet the perceived need for and current use of high-value care (HVC) curricula in pediatrics residency programs is unknown.

Objective 

We described the current national landscape of HVC curricula in pediatrics residencies, including characterization of current programs, barriers to the practice of HVC, and clarification of preferred curricula types.

Methods 

Using a cross-sectional study design, we conducted a national, anonymous, web-based survey of pediatrics residency program directors and pediatrics chief residents in fall 2014.

Results 

We received responses from 85 of 199 (43%) pediatrics program directors and 74 of 199 (37%) pediatrics chief residents. Only 10% (8 of 80) of program directors and 12% (8 of 65) of chief residents reported having a formal curriculum on HVC. Respondents identified the largest barriers to HVC as a lack of cost transparency (program directors) and attending physicians having the final say in treatment decisions (chief residents). The majority of respondents (83%, 121 of 146) agreed their program needs a HVC curriculum, and 90% (131 of 145) reported they would use a curriculum if it was available. Respondents significantly preferred a case-based conference discussion format over other approaches.

Conclusions 

Most pediatrics residency programs responding to a survey lacked formal HVC curricula. There is a desire nationally for HVC education in pediatrics, particularly in a case-based discussion format.
Canadian Occupational Performance Measure (COPM) in Primary Care: A Profile of Practice
Authors: Donnelly Catherine , O’Neill Colleen , Bauer Martha , Letts Lori
Published: October 2017

OBJECTIVE. This study aimed to understand how the Canadian Occupational Performance Measure (COPM) can be used as an outcome measure in primary care and to identify the occupational performance profiles in this setting.

METHOD. First, the COPM was administered to all eligible clients at two sites. Second, a focus group with participating occupational therapists explored the feasibility of using the COPM in primary care.

RESULTS. A total of 161 COPMs were initially administered. Self-care goals were identified most frequently (n = 248), followed by productivity (n = 229) and leisure (n = 179) goals (total goals = 656). Mean initial performance and satisfactions scores were 3.2 and 2.8, respectively. The average change (n = 22) scores were 2.1 and 2.6, respectively.

CONCLUSION. The COPM is an invaluable tool to guide initial assessments and offer an occupation-focused lens. Given the lifespan approach and an emphasis on screening and assessment, the challenge was finding the opportunity for readministration.
Impacts of Personal Experience: Informing Water Conservation Extension Education
Authors: Huang Pei-wen , Lamm Alexa J.
Published: October 2017

Extension educators have diligently educated the general public about water conservation. Incorporating audiences’ personal experience into educational programming is recommended as an approach to effectively enhance audiences’ adoption of water conservation practices. To ensure the impact on the audiences and environment, understanding the differences in issues audiences are concerned and audiences’ behavioral pattern is needed. This study examined the regional differences in how U.S. residents’ experiences with water issues related to their engagement and intention to engage in water conservation in order to facilitate the development of Extension educational programming in different regions. An online survey was administered to collect responses from U.S. residents in this descriptive and correlational study. Respondents’ water issues experience, water use behaviors, water conservation practice application, and willingness to act on water conservation were measured. Regional differences in how experience were associated with water use behaviors, water conservation practices application, and willingness to act were found. Extension educators should be aware of such regional differences when developing water conservation educational programs and provide recommendations tailored to regional audiences’ needs and interests. By doing so, audiences’ adoption of water conservation practices is expected to increase.
Towards Developing an Industry-Validated Food Technology Curriculum in Afghanistan
Authors: Ebner Paul , McNamara Kevin , Deering Amanda , Oliver Hailey , Rahimi Mirwais , Faisal Hamid
Published: October 2017

Afghanistan remains an agrarian country with most analyses holding food production and processing as key to recovery. To date, however, there are no public or private higher education departments focused on food technology. To bridge this gap, Herat University initiated a new academic department conferring BS degrees in food technology. Models for developing agriculture curricula consider industry input integral to preparing graduates for the job market. Here, we assessed perspectives of Afghan food processors on challenges faced and skills/knowledge valued most in new employees as a first step in developing an industry validated food technology curriculum for Afghanistan. Businesses identified numerous challenges (e.g., having to source technical assistance from outside the country) and specific skills gaps (e.g., ability to conduct quality analysis/assurance) they feel should be addressed by the university. Afghan higher education is largely teacher centered, however, with little to no integration of industry stakeholders and responses indicated that establishing beneficial relationships between stakeholders and university programs will take considerable effort. As Afghanistan continues higher education reform throughout the country with the addition of more “workforce” oriented degree programs, these results have implications extending to other areas of agriculture and beyond.
The Effects of an Experiential Approach to Learning on Student Motivation
Authors: Baker Marshall A. , Robinson J. Shane
Published: October 2017

Student motivation is often an overlooked product of classroom instruction. Researchers have repeatedly called for broader measures to adequately assess and understand the effects of various instructional methods. This study sought to determine the effects of an experiential approach to learning on student motivation, as defined by Keller’s (1987) ARCS model. Three research questions were established, and it was concluded that, (a) the type of instruction does not impact student motivation, (b) broad performance measures are not related to student motivation, and (c) learning style is related to student motivation. It was recommended that teachers vary their instruction to meet all learning styles, be purposeful in designing instruction as guided by Keller’s (1987) process questions to embed motivation, be aware of preferred teaching roles to be mindful of meeting all learning modes, and include motivation as an educational outcome.
Graduate STEM-Based Agriculture Education and Women Agriculturalists: An Agency Perspective
Authors: Mars Matthew M. , Hart Jeni
Published: October 2017

In this paper, we explored the academic and professional aspirations, experiences, and perspectives of 11 women pursuing graduate degrees based in the science, technology, engineering, and mathematics (STEM) fields within research-intensive agriculture colleges at three land grant research universities in the United States (U.S.). Using principles drawn from the theories of human agency (Bandura, 1989, 2001; Emirbayer & Mische, 1998; Locke, 1978; Lukes, 1973; Sewell, 1992; Terosky, Campbell, & O’Meara, 2014) and gendered organizations (Acker, 1990, 2012) as our conceptual guide, we explored the conditions and contexts that influence the academic experiences and professional trajectories of emergent women agriculturalists who are enrolled in STEM-based graduate programs. We were particularly attentive to how such experiences and trajectories aligned with agricultural environments that have been shown to be masculine (i.e., large-scale farming and agribusiness, STEM-based agricultural research, Extension). The study developed a deeper understanding of the institutionalized conditions that influence the participation and leadership of women in solving the agricultural problems that confront society and the human condition. Implications for graduate STEM-based agriculture education are discussed and recommendations for both practice and future research are proposed.
Facilities in School-Based, Agricultural Education (SBAE): A Historical Inquiry
Authors: Twenter Jason P. , Edwards M. Craig
Published: October 2017

Vocational education, including SBAE, reoriented as its role in U.S. public schools and society changed. However, the types of facilities in which to teach SBAE have remained somewhat consistent, even as the program’s curriculum became less dominated by a production agriculture orientation. We examined the historical evolution of learning spaces and related resources for teaching SBAE. Findings revealed the need for specialized facilities in SBAE was emphasized by several early 20th century education philosophers and elected officials. The work of these early supporters of vocational training coupled with significant national and international events contributed to enactment of key federal legislation, which provided impetus to states and local schools to fund learning spaces for SBAE. The spaces included classrooms, agricultural mechanics laboratories, greenhouses, land laboratories, and food processing centers as locations for students to learn, apply, and develop knowledge, attitudes, and skills. Going forward, we suggest a diverse stakeholder group examine the facility and equipment needs of SBAE as related to enhancing its ability to prepare students for career pathways and/or pursue postsecondary education aligned with entry into STEM-related occupations. We also recommend systematic efforts to forecast trends likely to presage the facility and equipment needs of SBAE in the future.
Evaluation of an Annual Community-Focused Agricultural Literacy Event
Authors: Sandlin M'Randa R. , Perez Kauahi
Published: October 2017

Agricultural literacy programs are effective pathways to informally teach the public about agriculture through stakeholder (attendee and exhibitor) interaction. Such programs are generally evaluated using attendee feedback but fail to include exhibitors’ experience. The purpose of this study was to evaluate a local community agricultural event by (a) exploring attendee agricultural literacy, purchasing behavior, and overall experience at the event, and (b) exploring exhibitor experiences at the same event. Attendees and exhibitors were given electronic surveys to provide quantitative and qualitative feedback as it pertained to the event’s educational programming aspects. Attendees reported positive attitudes and perceptions of locally produced agricultural goods. Exhibitors reported satisfaction with the event and found the interactive digital scavenger hunt to be an effective way to interact with attendees and increase exposure to their business. Suggestions from attendees and exhibitors were concerned with pre-event communication and event logistics. The findings identify areas where education could be beneficial (e.g., nutritional information, impact of purchasing locally grown agricultural products, and where to find/purchase locally grown agricultural products). We recommend including attendee and exhibitor feedback to evaluate and improve similar agricultural literacy programs to guide marketing strategies and to better engage attendees and exhibitors with integrated learning activities.
3D DIGITAL CADASTRE JOURNEY IN VICTORIA, AUSTRALIA
Authors: Shojaei D. , Olfat H. , Briffa M. , Rajabifard A.
Published: October 2017

Abstract. Land development processes today have an increasing demand to access three-dimensional (3D) spatial information. Complex land development may need to have a 3D model and require some functions which are only possible using 3D data. Accordingly, the Intergovernmental Committee on Surveying and Mapping (ICSM), as a national body in Australia provides leadership, coordination and standards for surveying, mapping and national datasets has developed the Cadastre 2034 strategy in 2014. This strategy has a vision to develop a cadastral system that enables people to readily and confidently identify the location and extent of all rights, restrictions and responsibilities related to land and real property. In 2014, the land authority in the state of Victoria, Australia, namely Land Use Victoria (LUV), has entered the challenging area of designing and implementing a 3D digital cadastre focused on providing more efficient and effective services to the land and property industry. LUV has been following the ICSM 2034 strategy which requires developing various policies, standards, infrastructures, and tools. Over the past three years, LUV has mainly focused on investigating the technical aspect of a 3D digital cadastre. This paper provides an overview of the 3D digital cadastre investigation progress in Victoria and discusses the challenges that the team faced during this journey. It also addresses the future path to develop an integrated 3D digital cadastre in Victoria.
CAPTURE AND THREE DIMENSIONAL PROJECTION OF NEW SOUTH
WALES STRATA PLANS IN LANDXML FORMAT
Authors: Harding B. , Foreman A.
Published: October 2017

Abstract. New South Wales is embarking on a major reform program named Cadastre NSW. This reform aims to move to a single source of truth for the digital representation of cadastre. The current lack of a single source cadastre has hindered users from government and industry due to duplication of effort and misalignment between databases from different sources. For this reform to be successful, there are some challenges that need to be addressed. “Cadastre 2034 – Powering Land & Real Property” (2015) published by the Intergovernmental Committee on Surveying and Mapping (ICSM) identifies that current cadastres do not represent real property in three dimensions. In future vertical living lifestyles will create complex property scenarios that the Digital Cadastral Database (DCDB) will need to contend with. While the NSW DCDB currently holds over 3 million lots and 5 million features, one of its limitations is that it does not indicate land ownership above or below the ground surface. NSW Spatial Services is currently capturing survey plans into LandXML format. To prepare for the future, research is being undertaken to also capture multi-level Strata Plans through a modified recipe. During this research, multiple Strata Plans representing a range of ages and development types have been investigated and converted to LandXML. Since it is difficult to visualise the plans in a two dimensional format, quality control purposes require a method to display these plans in three dimensions. Overall investigations have provided Spatial Services with enough information to confirm that the capture and display of Strata Plans in the LandXML format is possible.
CITYGML AND THE STREETS OF NEW YORK -
A PROPOSAL FOR DETAILED STREET SPACE MODELLING
Authors: Beil C. , Kolbe T. H.
Published: October 2017

Abstract. Three-dimensional semantic city models are increasingly used for the analysis of large urban areas. Until now the focus has mostly been on buildings. Nonetheless many applications could also benefit from detailed models of public street space for further analysis. However, there are only few guidelines for representing roads within city models. Therefore, related standards dealing with street modelling are examined and discussed. Nearly all street representations are based on linear abstractions. However, there are many use cases that require or would benefit from the detailed geometrical and semantic representation of street space. A variety of potential applications for detailed street space models are presented. Subsequently, based on related standards as well as on user requirements, a concept for a CityGML-compliant representation of street space in multiple levels of detail is developed. In the course of this process, the CityGML Transportation model of the currently valid OGC standard CityGML2.0 is examined to discover possibilities for further developments. Moreover, a number of improvements are presented. Finally, based on open data sources, the proposed concept is implemented within a semantic 3D city model of New York City generating a detailed 3D street space model for the entire city. As a result, 11 thematic classes, such as roadbeds, sidewalks or traffic islands are generated and enriched with a large number of thematic attributes.
WIRED AND WIRELESS CAMERA TRIGGERING WITH ARDUINO
Authors: Kauhanen H. , Rönnholm P.
Published: October 2017

Abstract. Synchronous triggering is an important task that allows simultaneous data capture from multiple cameras. Accurate synchronization enables 3D measurements of moving objects or from a moving platform. In this paper, we describe one wired and four wireless variations of Arduino-based low-cost remote trigger systems designed to provide a synchronous trigger signal for industrial cameras. Our wireless systems utilize 315 MHz or 434 MHz frequencies with noise filtering capacitors. In order to validate the synchronization accuracy, we developed a prototype of a rotating trigger detection system (named RoTriDeS). This system is suitable to detect the triggering accuracy of global shutter cameras. As a result, the wired system indicated an 8.91 μs mean triggering time difference between two cameras. Corresponding mean values for the four wireless triggering systems varied between 7.92 and 9.42 μs. Presented values include both camera-based and trigger-based desynchronization. Arduino-based triggering systems appeared to be feasible, and they have the potential to be extended to more complicated triggering systems.
TIME SERIES OF IMAGES TO IMPROVE TREE SPECIES CLASSIFICATION
Authors: Miyoshi G. T. , Imai N. N. , de Moraes M. V. A. , Tommaselli A. M. G. , Näsi R.
Published: October 2017

Abstract. Tree species classification provides valuable information to forest monitoring and management. The high floristic variation of the tree species appears as a challenging issue in the tree species classification because the vegetation characteristics changes according to the season. To help to monitor this complex environment, the imaging spectroscopy has been largely applied since the development of miniaturized sensors attached to Unmanned Aerial Vehicles (UAV). Considering the seasonal changes in forests and the higher spectral and spatial resolution acquired with sensors attached to UAV, we present the use of time series of images to classify four tree species. The study area is an Atlantic Forest area located in the western part of São Paulo State. Images were acquired in August 2015 and August 2016, generating three data sets of images: only with the image spectra of 2015; only with the image spectra of 2016; with the layer stacking of images from 2015 and 2016. Four tree species were classified using Spectral angle mapper (SAM), Spectral information divergence (SID) and Random Forest (RF). The results showed that SAM and SID caused an overfitting of the data whereas RF showed better results and the use of the layer stacking improved the classification achieving a kappa coefficient of 18.26 %.
FOREST RESOURCE MEASUREMENTS BY COMBINATION OF TERRESTRIAL LASER SCANNING AND DRONE USE
Authors: Cheung K. , Katoh M. , Horisawa M.
Published: October 2017

Abstract. Using terrestrial laser scanning (TLS), forest attributes such as diameter at breast height (DBH) and tree location can be measured accurately. However, due to low penetration of laser pulses to tree tops, tree height measurements are typically underestimated. In this study, data acquired by TLS and drones were combined; DBH and tree locations were determined by TLS, and tree heights were measured by drone use. The average tree height error and root mean square error (RMSE) of tree height were 0.8 and 1.2 m, respectively, for the combined method, and –0.4 and 1.7 m using TLS alone. The tree height difference was compared using airborne laser scanning (ALS). Furthermore, a method to acquire 100 % tree detection rate based on TLS data is suggested in this study.
SNAPSHOT SPECTRAL AND COLOR IMAGING USING A REGULAR DIGITAL CAMERA WITH A MONOCHROMATIC IMAGE SENSOR
Authors: Hauser J. , Zheludev V. A. , Golub M. A. , Averbuch A. , Nathan M. , Inbar O. , Neittaanmäki P. , Pölönen I.
Published: October 2017

Abstract. Spectral imaging (SI) refers to the acquisition of the three-dimensional (3D) spectral cube of spatial and spectral data of a source object at a limited number of wavelengths in a given wavelength range. Snapshot spectral imaging (SSI) refers to the instantaneous acquisition (in a single shot) of the spectral cube, a process suitable for fast changing objects. Known SSI devices exhibit large total track length (TTL), weight and production costs and relatively low optical throughput. We present a simple SSI camera based on a regular digital camera with (i) an added diffusing and dispersing phase-only static optical element at the entrance pupil (diffuser) and (ii) tailored compressed sensing (CS) methods for digital processing of the diffused and dispersed (DD) image recorded on the image sensor. The diffuser is designed to mix the spectral cube data spectrally and spatially and thus to enable convergence in its reconstruction by CS-based algorithms. In addition to performing SSI, this SSI camera is capable to perform color imaging using a monochromatic or gray-scale image sensor without color filter arrays.
MULTIMODAL DATA FUSION FOR EFFECTIVE SURVEILLANCE OF CRITICAL INFRASTRUCTURE
Authors: Kandylakis Z. , Karantzalos K. , Doulamis A. , Karagiannidis L.
Published: October 2017

Abstract. Monitoring critical infrastructures, especially those that are covering wide-zones, is of fundamental importance and priority for modern surveillance systems. The concurrent exploitation of multisensor systems, can offer additional capabilities, on day and night acquisitions and different environmental/illumination conditions. Towards this direction, we have designed a multi-sensor system based on thermal, shortwave infrared and hyperspectral video sensors. Based on advanced registration, dynamic background modelling and data association techniques, possible moving targets are detected on the thermal and shortwave infrared modalities. In order to avoid the computational intensive co-registration with the hyperspectral video streams, the detected targets are projected through a local coordinate system on the hypercube image plane. The final detected and verified targets are extracted through fusion and data association, based on temporal spectral signatures and target/background statistics. The developed multisensor system for the surveillance of critical infrastructure has been validated for monitoring wide-zones against different conditions showcasing abilities for detecting and tracking moving targets through fog and smoke.

The primary root of heat islands in cities is in absorption of solar radiation by the mass of building structures, roads and other solid materials. The absorbed heat is subsequently re-radiated into the surroundings and increases ambient temperatures. The vegetation can stop and absorb most of incoming solar radiation mostly via the photosynthesis and evapotranspiration process. However, vegetation in mild climate of Europe manifests considerable annual seasonality which can also contribute to the seasonal change in the cooling effect of the vegetation on the urban climate. Modern methods of high-resolution mapping and new generations of sensors have brought opportunity to record the dynamics of urban greenery in a high resolution in spatial, spectral, and temporal domains. In this paper, we use the case study of the city of Košice in Eastern Slovakia to demonstrate the methodology of 3D mapping and modelling the urban greenery during one vegetation season in 2016. The purpose of this monitoring is to capture 3D effects of urban greenery on spatial distribution of solar radiation in urban environment. Terrestrial laser scanning was conducted on four selected sites within Košice in ultra-high spatial resolution. The entire study area, which included these four smaller sites, comprised 4 km2 of the central part of the city was flown within a single airborne lidar and photogrammetric mission to capture the upper parts of buildings and vegetation. The acquired airborne data were used to generate a 3D city model and the time series of terrestrial lidar data were integrated with the 3D city model. The results show that the terrestrial and airborne laser scanning techniques can be effectively used to monitor seasonal changes in foliage of trees in order to assess the transmissivity of the canopy for microclimate modelling.

Pedagogical contributions of Arnold Schönberg composition’s method
Authors: Gustems Carnicer Josep , Polo Pujadas Magda
Published: October 2017

Arnold Schoenberg’s twelve-tone technique made him one of the most influential composers of the twentieth century, but his contribution to music pedagogy remains far less well known. This article is a descriptive and interpretive work and therefore tries to present the main ideas of Schönberg, from theoretical references. This paper explores Schoenberg’s concepts about music education as they emerge in the collection of essays published under the title Style and Idea: the dialectic between tradition and modernity; the social dimensions of music education; the notion of musicality; the presence of emotion in twelve-tone composition; and the composer’s conviction that contemporary creation could be an axis of music education. This research also argues that Schoenberg’s ideas about music education make him deserving of greater attention amongst music teachers and pedagogues today.
¿Cómo enseñan nuestros maestros de instrumento musical? Situación de la enseñanza de estrategias de práctica efectiva en seis escuelas de música en México
Authors: Capistrán Gracia Raúl Wenceslao
Published: October 2017

Este artículo presenta los resultados de un estudio exploratorio que tuvo como objetivo determinar el nivel de enseñanza de estrategias de práctica efectiva por parte de 84 profesores de instrumento en seis departamentos universitarios de música en México. A través de la técnica de la encuesta, los profesores respondieron un cuestionario que incluyó preguntas contextuales y preguntas con escalas tipo Likert y opción múltiple para determinar su nivel de compromiso para enseñar estrategias de practica efectiva, la manera de monitorizar la práctica de sus estudiantes, el grado de satisfacción con su desempeño, su opinión respecto a los recursos que podrían mejorar el proceso de enseñanza y aprendizaje instrumental, la manera como se mantienen actualizados y su filosofía de enseñanza. Los datos fueron capturados y analizados con la ayuda del programa de computación Statistics Package for the Social Sciences IBM SPSS 2.0. Los resultados sugieren que los profesores encuestados poseen un alto nivel de compromiso; sin embargo, se detectaron algunos aspectos mejorables, tales como deficiencias en la enseñanza de estrategias relacionadas con el control de ejecución y la autoevaluación, falta de monitorización efectiva de la práctica de sus estudiantes, así como falta de interés en fundamentar su práctica docente en resultados de investigación. Adicionalmente, los resultados indican que las instituciones se preocupan poco por promover la impartición de cursos de pedagogía del instrumento. El investigador propone algunas recomendaciones en las secciones de discusión y conclusiones
Heinrich Neuhaus: intuición y método en la enseñanza del piano
Authors: Márquez Sánchez Salve , Méndiz Noguero Alfonso
Published: October 2017

Heinrich Neuhaus fue un destacado protagonista en la creación y evolución de la escuela pianística soviética. Profesor del Conservatorio de Moscú desde 1922 hasta su muerte en 1964, sus particulares métodos de enseñanza atrajeron muy pronto la atención de músicos y pedagogos. El interés que suscitó su estilo docente hizo que se realizaran grabaciones de algunas de sus sesiones de clases, dando así lugar a un valioso material en el que se incluyen registros estenográficos y grabaciones sonoras. En este trabajo se ha llevado a cabo un detallado análisis de estas fuentes junto al estudio de sus artículos, cartas y otros documentos personales —en su mayoría sin traducir y poco conocidos en Occidente—, para así profundizar en la comprensión del enfoque humanista de su método docente. También se exploran las prácticas que hicieron de Neuhaus un pedagogo de una influencia excepcional, y se ofrece un detallado análisis de sus sesiones de clase, incluyendo estrategias metodológicas y de organización.
La defensa de la educación musical desde las neurociencias
Authors: Peñalba Acitores Alicia
Published: October 2017

La educación musical actual está atravesando un momento de crisis a nivel global (Aróstegui, 2016). Los modelos curriculares priorizan algunas materias en detrimento de otras consideradas menos importantes o secundarias, como ocurre en el caso de la música. La preocupación desde esta área ha impulsado la publicación de numerosos artículos científicos que abordan la defensa de la educación musical en las escuelas. En este artículo se analizan las aportaciones de las neurociencias presentes en la literatura sobre "defensa de la educación musical" y se discute su solidez como argumento.
Evaluación en Educación Musical en la Educación Básica: una reflexión desde la percepción del profesorado
Authors: Magnitzky Vargas David Whidden , Sepúlveda Ortega Andrea Bernardita
Published: October 2017

En virtud de la evolución histórica de la educación musical en Chile, en el marco de las tres reformas curriculares correspondientes a los años 1965, 1981, 1996 y 1998, es posible advertir cambios experimentados en la estructura curricular de la asignatura, conforme a los procesos sociales y necesidades educativas de cada época referida. No obstante, hasta la fecha aún constituye una problemática la discusión acerca de la conceptualización que se tiene de evaluación y cómo ésta se debe aplicar en términos prácticos. En este marco, en la actualidad se cuenta con el aporte teórico de connotados académicos como: Pujol, Santos Guerra, Poblete y Fautley, así como los lineamientos del Ministerio de Educación, a través de sus Programas de Estudio de primero hasta octavo año básico. Si bien esta última institución entrega sugerencias y enfoques que propenden a identificar algunos aspectos que pueden ser observados y potenciados en los estudiantes, estableciendo en nuestro país lineamientos en torno a ¿qué se debe evaluar?, ¿cómo se debe evaluar? y ¿para qué se evalúa?, persisten ciertas confusiones sobre el proceso de evaluación por parte de algunos docentes. En este sentido se orienta la presente investigación, pues es fundamental comprender desde una perspectiva Constructivista, la percepción que tienen los docentes en torno al concepto de evaluación, al impacto de la evaluación que reconocen en sus estudiantes y las decisiones que consideran para mejorar el proceso de enseñanza-aprendizaje a través de la información rescatada de las evaluaciones. A partir del estudio realizado se develan percepciones que responden a componentes cognitivos, afectivos y conductuales, que ofrecen una interesante reflexión que se invita a rescatar en las siguientes páginas.

The Clown Suicides: The Death and Cinematic Afterlife of Marceline Orbes and Francis “Slivers” Oakley, New York's Superstar Clowns, in Charlie Chaplin's Limelight
Authors: Reid Darren R.
Published: October 2017

Although generally seen as an autobiographical piece, a film that reflects on the declining popularity of its director and star, Charlie Chaplin's Limelight (1952) is a sharp, albeit obscured commentary on the lives of two of the twentieth century's most important forgotten comedians. The names of Marceline Orbes and Francis “Slivers” Oakley mean almost nothing today, but these comedians were hugely influential, inspiring not only Chaplin but also Buster Keaton. Orbes and Oakley shared a focus on pathos and the mime that helped to provide Chaplin and Keaton with their comic framework. Though their careers were destroyed by the rise of cinematic comedy (and the performers whom they had helped to inspire), a development that led to their suicides, the influence of Orbes and Oakley was long lasting thanks to those successful big-screen comedians who understood and internalized their works.

Published: October 2017

Traditionally, a therapy dog has been a complimentary tool used by healthcare providers to provide stress relief to patients. However, animals can perform functions at an even greater capacity. Service animals are becoming a part of the healthcare team, by providing unique assistance to the healthcare providers rather than the patients. Thus, the workforce has expanded to include service dogs as a part of the healthcare team. This article discusses the unique challenges and opportunities provided by the use of service animal as a part of the healthcare team, as provided by the piloted use of a service animal with a student nurse in an acute care facility.
