    Leal Insua, Maria Pilar

    This thesis is focused on the Scientific area of the Programs of Curricular Diversification, one of the Government actions for the attention to diversity in compulsory Secondary Education, established in the General Education Law (LOGSE: Ley de Ordenacion General del Sistema Educativo) of 1990. It has been carried out in Spain. In the thesis two different lines of work can be distinguished: (A) The analysis of material elaborated specifically for the mentioned area. We intent to know what materials have been elaborated and to analyze them; to this purpose we study the material spread in Congresses or Conferences, and also the articles published in magazines or specifically designed to be used in the Scientific area of the Programs of Curricular Diversification until year 2003. The analysis is made after classifying the material according to the format in which it appears (books, CDs, "Didactic Units"). (B) Two case studies, of evaluative character, carried out in two Secondary Schools in the province of Segovia (Spain), one of them in the city and another one in a rural population. The case studies are centered in the Scientific Area of the Programs of Curricular Diversification that last for two years. In the first of these Centers eight students took part in the Program; in the second, a total of seven. Throughout the investigation we observed that students who took part in the Programs obtained good academic results. Programs are proved to be effective in generating processes of academic success in pupils who were previously in situation of school failure and at risk of social exclusion. The success of these programs is fundamentally due to the following reasons: the low number of students involved, the fact that they are focused on basic knowledge, the reduced number of subjects studied. Besides, to offer the students the chance of a closer relationship with a few teachers increases their motivation and involvement in the programs. Key words: Attention to

  2. A New Approach to Authoring Interactive Curricular Material

    It is still not common to find computer-based interactive material incorporated into mainstream teaching. Learning the intricacies of a software package is a poor investment of time if the half-life of the textbook is longer than the half-life of the computer technology. Internet technologies are likely to change this situation. This talk describes a set of Java applets, known as Physlets, which make use of these technologies. Physlets are designed to communicate with browsers by employing a scripting language such as JavaScript, thereby allowing one applet to be used in many different contexts. This approach makes it possible to use a modular object-oriented approach for the design of material. But this is not enough. Effective curriculum development must couple our software design philosophy with research into the effectiveness of computer-based instruction. Examples of Physlet-based curricular material will be presented.

    The Next Generation Science Standards (NGSS) describe teaching and learning goals for Earth system science at all levels of K-12, including elementary, middle school, and high school. Teachers must consider science and engineering practices, cross-cutting concepts, and disciplinary core ideas. The National Science Foundation and other federal organizations have supported the development of reformed curricular materials at the K-12 level for many years. Although developed before the adoption of NGSS, many of these Earth system science resources are, in fact, NGSS congruent. Such resources include those developed by TERC, SERC, EDC, NASA, NOAA, USGS, and others. This session features NGSS congruent materials, carefully examining and dissecting the performance expectations that embody these materials. It also shares a process of tagging these materials via NSTA's, NGSS portal guidelines.

    2014-07-01

    There is an imminent shortage of skilled workforce facing Europe's hi-tech industries mainly due to the declining interest of young people in science and engineering careers. To avert this trend the European Union funded the development of the `Photonics Explorer' - an intra-curricular educational kit designed to engage, excite and educate students about the fascination of working with optics hands-on, in their own classrooms! Each kit equips teachers with class sets of experimental components provided within a supporting didactic framework based on guided inquiry based learning techniques. The material has been specifically designed to integrate into the curriculum and enhance and complement the teaching and learning of science in the classroom. The kits are provided free of charge to teachers, in conjunction with teacher training courses. The main challenge of this program was the development of educational material that seamlessly integrates into the various national curricula across Europe. To achieve this, the development process included a preparatory EU wide curricula survey and a special `Review and Revise' process bringing together the expertise of over 35 teachers and pedagogic experts. This paper reports on the results of the preparatory study which identified two specific age groups at secondary schools for photonics educational material, the didactic content of the Photonics Explorer kit resulting from a pan-European collaboration of key stakeholders, EU wide dissemination and sustainability of the program.

  8. Transforming Spatial Reasoning Skills in the Upper-Level Undergraduate Geoscience Classroom Through Curricular Materials Informed by Cognitive Science Research

    Spatial visualization is an essential skill in the STEM disciplines, including the geosciences. Undergraduate students, including geoscience majors in upper-level courses, bring a wide range of spatial skill levels to the classroom. Students with weak spatial skills may be unable to understand fundamental concepts and to solve geological problems with a spatial component. However, spatial thinking skills are malleable. As a group of geoscience faculty members and cognitive psychologists, we have developed a set of curricular materials for Mineralogy, Sedimentology & Stratigraphy, and Structural Geology courses. These materials are designed to improve students' spatial skills, and in particular to improve students' abilities to reason about spatially complex 3D geological concepts and problems. Teaching spatial thinking in the context of discipline-based exercises has the potential to transform undergraduate STEM education by removing one significant barrier to success in the STEM disciplines. The curricular materials we have developed are based on several promising teaching strategies that have emerged from cognitive science research on spatial thinking. These strategies include predictive sketching, making visual comparisons, gesturing, and the use of analogy. We have conducted a three-year study of the efficacy of these materials in strengthening the spatial skills of students in upper-level geoscience courses at three universities. Our methodology relies on a pre- and post-test study design, with several tests of spatial thinking skills administered at the beginning and end of each semester. In 2011-2012, we used a "business as usual" approach to gather baseline data, measuring how much students' spatial thinking skills improved in response to the existing curricula. In the two subsequent years we have incorporated our new curricular materials, which can be found on the project website: http://serc.carleton.edu/spatialworkbook/activities.html Structural Geology

    InTeGrate is NSF's STEP Center in the geosciences. A major goal of the project is to develop curricula that will increase the geoscience literacy of all students such that they are better positioned to make sustainable decisions in their lives and as part of the broader society. This population includes the large majority of students that do not major in the geosciences, those historically under-represented in the geosciences, and future K-12 teachers. To achieve this goal, we established a model for the development of curricular materials that draws on the distributed expertise of the undergraduate teaching community. Our model seeks proposals from across the higher education community for courses and modules that meet InTeGrate's overarching goals. From these proposals, we select teams of 3-5 instructors from three or more different institutions (and institution types) and pair them with assessment and web experts. Their communication and development process is supported by a robust, web-based content management system (CMS). Over two years, this team develops materials that explicitly address a geoscience-related societal challenge, build interdisciplinary problem-solving skills, make use of real geoscience data, and incorporate geoscientific and systems thinking. Materials are reviewed with the InTeGrate design rubric and then tested by the authors in their own courses, where student learning is assessed. Results are reviewed by the authors and our assessment team to guide revisions. Several student audiences are targeted: students in general education and introductory geoscience courses, pre-service K-12 teachers, students in other science and engineering majors, as well as those in the humanities and social sciences. Curriculum development team members from beyond the geosciences are critical to producing materials that can be adopted for all of these audiences, and we have been successful in engaging faculty from biology, economics, engineering, sociology

    2014-12-01

    Designing climate change curricular materials suitable for wide adoption across institutions and academic disciplines (including those outside of the geosciences) requires collaboration among faculty at different types of institutions and consideration of a variety of student populations, learning styles, and course formats. The Interdisciplinary Teaching of Geoscience for a Sustainable Future (InTeGrate) project, an NSF STEP Center program, provides opportunities for faculty to develop 2-3 week teaching modules to engage students in understanding the intersections between geoscience topics and societal issues. From 2012-2014, a team of 3 faculty from a liberal arts college, comprehensive university, and community college developed, implemented, assessed, and revised a 2-3 week module for introductory undergraduates entitled "Climate of change: interactions and feedbacks between water, air, and ice". The module uses authentic atmosphere, ocean, and cryosphere data from several regions to illustrate how climate impacts human societies and that the climate system has interacting components complicated by feedbacks, uncertainties, and human behavioral decisions. Students also consider past and present human adaptations to climate fluctuations. The module was piloted in introductory geology, meteorology, and oceanography courses during the 2012-2013 academic year, during which time formative and summative assessments were administered and used to modify the curricular materials. We will provide an overview of the module's content, instructional strategies involved in implementing the module, and methods of formative and summative assessment. We will also report on lessons learned during the development, piloting, revision, and publishing process, the importance of fostering partnerships between faculty from different institution types, and design approaches that promote widespread adoption of climate curricular materials.

    Sustainability is emerging as a central theme for teaching about the environment, whether it be from the perspective of science, economics, or society. The Systems, Society, Sustainability and the Geosciences workshop provided 48 undergraduate faculty from 46 institutions a forum to discuss the challenges and possibilities for integrating geoscience concepts with a range of other disciplines to teach about the fundamentals of sustainability. Participants from community college to doctorate-granting universities had expertise that included geosciences, agriculture, biological sciences, business, chemistry, economics, ethnic studies, engineering, environmental studies, environmental education, geography, history, industrial technology, landscape design, philosophy, physics, and political science. The workshop modeled a range of teaching strategies that encouraged participants to network and collaborate, share successful strategies and materials for teaching sustainability, and identify opportunities for the development of new curricular materials that will have a major impact on the integration of geosciences into the teaching of sustainability. The workshop design provided participants an opportunity to reflect upon their teaching, learning, and curriculum. Throughout the workshop, participants recorded their individual and collective ideas in a common online workspace to which all had access. A preliminary synthesis of this information indicates that the concept of sustainability is a strong organizing principle for modern, liberal education requiring systems thinking, synthesis and contributions from all disciplines. Sustainability is inherently interdisciplinary and provides a framework for educational collaboration between and among geoscientists, natural/physical scientists, social scientists, humanists, engineers, etc.. This interdisciplinary framework is intellectually exciting and productive for educating students at all levels of higher education

    Hodgson, Alfred T.; Ming, Katherine Y.; Singer, Brett C.

    2005-01-05

    The dynamic behavior of volatile organic compounds (VOCs) in indoor environments depends, in part, on sorptive interactions between VOCs in the gas phase and material surfaces. Since information on the types and quantities of interior material surfaces is not generally available, this pilot-scale study was conducted in occupied residences to develop and demonstrate a method for quantifying surface areas of objects and materials in rooms. Access to 33 rooms in nine residences consisting of bathrooms, bedroom/offices and common areas was solicited from among research group members living in the East San Francisco Bay Area. A systematic approach was implemented for measuring rooms and objects from 300 cm{sup 2} and larger. The ventilated air volumes of the rooms were estimated and surface area-to-volume ratios were calculated for objects and materials, each segregated into 20 or more categories. Total surface area-to-volume ratios also were determined for each room. The bathrooms had the highest total surface area-to-volume ratios. Bedrooms generally had higher ratios than common areas consisting of kitchens, living/dining rooms and transitional rooms. Total surface area-to-volume ratios for the 12 bedrooms ranged between 2.3 and 4.7 m{sup 2} m{sup -3}. The importance of individual objects and materials with respect to sorption will depend upon the sorption coefficients for the various VOC/materials combinations. When combined, the highly permeable material categories, which may contribute to significant interactions, had a median ratio of about 0.5 m{sup 2} m{sup -3} for all three types of rooms.

    In support of the Department of Energy’s continued plans to de-inventory and reduce the footprint of Cold War era weapons’ material production sites, the K-Area Material Storage (KAMS) facility, located in the K-Area Complex (KAC) at the Savannah River Site reservation, has expanded since its startup authorization in 2000 to accommodate DOE’s material consolidation mission. During the facility’s growth and expansion, KAMS will have expanded its authorization capability of material types and storage containers to allow up to 8200 total shipping containers once the current expansion effort completes in 2014. Recognizing the need to safely and cost effectively manage other surplus material across the DOE Complex, KAC is constantly evaluating the storage of different material types within K area. When modifying storage areas in KAC, the Documented Safety Analysis (DSA) must undergo extensive calculations and reviews; however, without an extensive and proven security posture the possibility for expansion would not be possible. The KAC maintains the strictest adherence to safety and security requirements for all the SNM it handles. Disciplined Conduct of Operations and Conduct of Projects are demonstrated throughout this historical overview highlighting various improvements in capability, capacity, demonstrated cost effectiveness and utilization of the KAC as the DOE Center of Excellence for safe and secure storage of surplus SNM.

    When curricular materials are disseminated to new sites, there can be a tension between fidelity to the original intent of the developers and adaptation to local needs. In this case study we look at a lab activity that was initially developed for an introductory physics for the life sciences (IPLS) course at the University of Maryland, then implemented at George Mason University with significant adaptations. The goals of the two implementations were overlapping, but also differed in ways that are reflected in the two versions of the lab. We compare student lab report data from the two sites to examine the impacts of the adaptation on how students engaged with the lab.

    Pediatric Hospital Medicine (PHM) is an emerging field in pediatrics and one that has experienced immense growth and maturation in a short period of time. Evolution and rapid expansion of the field invigorated the goal of standardizing PHM fellowship curricula, which naturally aligned with the field's evolving pursuit of a defined identity and consideration of certification options. The national group of PHM fellowship program directors sought to establish curricular standards that would more accurately reflect the competencies needed to practice pediatric hospital medicine and meet future board certification needs. In this manuscript, we describe the method by which we reached consensus on a 2-year curricular framework for PHM fellowship programs, detail the current model for this framework, and provide examples of how this curricular framework may be applied to meet the needs of a variety of fellows and fellowship programs. The 2-year PHM fellowship curricular framework was developed over a number of years through an iterative process and with the input of PHM fellowship program directors (PDs), PHM fellowship graduates, PHM leaders, pediatric hospitalists practicing in a variety of clinical settings, and other educators outside the field. We have developed a curricular framework for PHM Fellowships that consists of 8 education units (defined as 4 weeks each) in 3 areas: clinical care, systems and scholarship, and individualized curriculum.

Justicia curricular evoca no sólo al derecho a aprender, sino a que dichos aprendizajes sean valiosos para la gestión de la autonomía y la participación activa en las esferas públicas y privadas de la sociedad contemporánea. Concluimos que el concepto de justicia curricular orientado a la promoción de aprendizajes significativos y valiosos es una vía potente para reestructurar los centros educativos y la vida al interior de las aulas.

    salud De esta forma, nuestra trayectoria en la construcción de la asignatura, posibilitó la comprensión de la historicidad de las Prácticas Educativas en la Salud y los presupuestos que han orientado el análisis crítico del l desarrollo de estas prácticas.This work presents the process of building a subject named Educational Practice in Health Area, which has become part of the curricular program since 2006 and has been developed in the Nursing course in Campinas University, Campinas, SP. This study was accomplished by trying to put together Education, Health and Cultural Studies, going through these fields and keeping them connected to other possibilities of building up the pedagogical knowledge for the graduating nurse. During the classes important topics were discussed, such as conceptions of the human being, of the body, health, the education-health relation, among others. In this context, interlocutions were established to shake the paradigms, the speeches and the practice in Health Area. Hence, our trajectory towards the discipline enabled us to understand the historicity of Educational Practice in Health Area and the purposes that have guided them to support critical analysis in developing those practices.

    Nanostructured chromium(III)-oxide-based materials using sol-gel processing and a synthetic route for producing such materials are disclosed herein. Monolithic aerogels and xerogels having surface areas between 150 m.sup.2/g and 520 m.sup.2/g have been produced. The synthetic method employs the use of stable and inexpensive hydrated-chromium(III) inorganic salts and common solvents such as water, ethanol, methanol, 1-propanol, t-butanol, 2-ethoxy ethanol, and ethylene glycol, DMSO, and dimethyl formamide. The synthesis involves the dissolution of the metal salt in a solvent followed by an addition of a proton scavenger, such as an epoxide, which induces gel formation in a timely manner. Both critical point (supercritical extraction) and atmospheric (low temperature evaporation) drying may be employed to produce monolithic aerogels and xerogels, respectively.

    Full Text Available Industrialization of electrofluidic devices requires both high performance coating laminates and efficient material utilization on large area substrates. Here we show that screen printing can be effectively used to provide homogeneous pin-hole free patterned amorphous fluoropolymer dielectric layers to provide both the insulating and fluidic reversibility required for devices. Subsequently, we over-coat photoresist using slit coating on this normally extremely hydrophobic layer. In this way, we are able to pattern the photoresist by conventional lithography to provide the chemical contrast required for liquids dosing by self-assembly and highly-reversible electrofluidic switching. Materials, interfacial chemistry, and processing all contribute to the provision of the required engineered substrate properties. Coating homogeneity as characterized by metrology and device performance data are used to validate the methodology, which is well-suited for transfer to high volume production in existing LCD cell-making facilities.

This study investigates the objectives of communicative language teaching and curricular components of two important textbooks which are widely studied in Iran: the New Headway Advanced Series (2015, the Iran Language Institute (ILI Advanced1 (2008. The evaluation is done in terms of two prospects; firstly, the interpretation of communicative language teaching objectives and secondly, curricular components of the books. To this aim, a checklist of 5 Cs standards and seven curricular components evaluation developed by American Council on the Teaching of Foreign Languages (ACTFL was employed. The evaluation reveals that the New Headway advanced series is more preferable and desirable than the ILI Advanced 1 due to the design and organization, authenticity, attractiveness, functionality, practicality and the other qualities mentioned above regarding communication, cultures, connection, comparison, and community in all aspects. The evaluation based on the seven curricular components- language systems, communication strategies, cultural knowledge, learning strategies, content from other subject areas, critical thinking skills, technology and the other features- indicates that the ILI textbook enjoys low standards and is not well developed in all components. The ILI textbook is highly reading and writing oriented and not appropriate for transactional and interactional learning purposes. This study acquaints language teachers and learners with the more desirable and cogent book.

    Full Text Available The 21st century sets out new challenges to universities and university professors,who have to debate on the quality of education, the requirements on the teaching and learning, and the proposed curricula for the professional and disciplinary training in the university. In this context, research groups from four Colombian universities have developed a project in order to articulate therelationshipswithin the training of university professors, through the research of their practices and processes of curricular innovation. With such a goal the conformation of pedagogical collectives is promoted, and a reflective process about their pedagogical styles is generated (Callejas&,Corredor, 2002. Action research as a methodology and strategy of professional evelopment is proposed (McKernan, 1999, observation-reflection, planning-action, and then back to observation-reflection.Video recordings of classes, individual and group observation of the recordings, and individual and group interviews that favor reflection processes about the dimensions of the pedagogical style are performed. The analysis of the practice is guided by a complex, investigative and comprehensive vision of the curriculum that articulates theory and practice. The critical recognition that teachers do about their own pedagogical style favors the evolution of their ideas and guides them to start a process of curricular innovation.

    As nuclear research has become more prevalent, environmental contamination from the disposal of radioactive waste has become a prominent issue. At Los Alamos National Laboratory (LANL) in northern New Mexico, radioactive contamination from disposal operations has raised some very specific concerns. Material Disposal Area G (Area G) is the primary low-level radioactive waste disposal site at LANL and occupies an area adjacent to land belonging to the Native American community of the Pueblo of San Ildefonso. Analyses of soil and vegetation collected from the perimeter of Area G have shown concentrations of radionuclides greater than background concentrations established for northern New Mexico. As a result, Pueblo residents had become concerned that contaminants from Area G could enter tribal lands through various ecological pathways. The residents specifically questioned the safety of consuming meat from elk and deer that forage near Area G and then migrate onto tribal lands. Consequently, this study addresses the uptake of {sup 3}H, {sup 90}Sr, {sup tot}U, {sup 238}Pu, {sup 239}Pu, {sup 241}Am, and {sup 137}Cs by elk (Cervus elaphus) and deer (Odocoileus hemionus) that forage around the perimeter of Area G and the associated doses to the animals and to humans who consume these animals. Radionuclide uptake by and internal dose to animals was estimated using equations modified from National Council on Radiological Protection Report 76. The Residual Radiation computer code was used to estimate the external dose to animals and the dose to humans consuming meat. Soil and water concentrations from the perimeter of Area G and from background regions in northern New Mexico were averaged over 4 years (1993--1996) and used as input data for the models. Concentration estimates generated by the model correspond to the concentration range measured in actual tissue samples from elk and deer collected at LANL. The highest dose estimates for both animals (0.028 mrad/d) and humans

    Silicon carbide based materials and devices have been successfully exploited for diverse electronic applications. However, they have not achieved the same success as Si technologies due to higher material cost and higher processing temperatures required for device development. Traditionally, SiC is not considered for optoelectronic applications because it has an indirect bandgap. However, AppliCote Associates, LLC has developed a laser-based doping process which enables light emission in SiC through the creation of embedded p-n junctions. AppliCote laser irradiation of silicon carbide allows two different interaction mechanisms: (1) Laser conversion or induced phase transformation which creates carbon rich regions that have conductive properties. These conductive regions are required for interconnection to the light emitting semiconducting region. (2) Laser doping which injects external dopant atoms into the substrate that introduces deep level transition states that emit light when electrically excited. The current collaboration with AppliCote has focused on the evaluation of ORNL's unique Pulse Thermal Processing (PTP) technique as a replacement for laser processing. Compared to laser processing, Pulse Thermal Processing can deliver similar energy intensities (20-50 kW/cm2) over a much larger area (up to 1,000 cm2) at a lower cost and much higher throughput. The main findings of our investigation; which are significant for the realization of SiC based optoelectronic devices, are as follows: (1) The PTP technique is effective in low thermal budget activation of dopants in SiC similar to the laser technique. The surface electrical conductivity of the SiC samples improved by about three orders of magnitude as a result of PTP processing which is significant for charge injection in the devices; (2) The surface composition of the SiC film can be modified by the PTP technique to create a carbon-rich surface (increased local C:Si ratio from 1:1 to 2.9:1).

    Large specific surface area materials attract wide attention because of their applications in adsorption, catalysis, and nanotechnology. In the present study, we describe the synthesis and characterization of nanostructured amorphous silica materials. These materials were obtained by means of a modification of the Stobe-Fink-Bohn (SFB) method. The morphology and essential features of the synthesized materials have been studied using an automated surface area and pore size analyzer and scanning electron microscopy. The existence of a micro/mesoporous structure in the obtained materials has been established. It was also found that the obtained particle packing materials show large specific surface area up to 1,600 m2/g. (To our best knowledge, there is no any reported amorphous silica material with such a higher specific surface area.) The obtained materials could be useful in the manufacture of adsorbents, catalyst supports, and other nanotechnological applications.

    Objective. To identify and address areas for curricular improvement by evaluating student achievement of expected learning outcomes and competencies on annual milestone examinations. Design. Students were tested each professional year with a comprehensive milestone examination designed to evaluate student achievement of learning outcomes and professional competencies using a combination of multiple-choice questions, standardized patient assessments (SPAs), and objective structured clinical examination (OSCE) questions. Assessment. Based on student performance on milestone examinations, curricular changes were instituted, including an increased emphasis on graded comprehensive cases, OSCE skills days, and use of patient simulation in lecture and laboratory courses. After making these changes, significant improvements were observed in second and third-year pharmacy students’ grades for the therapeutic case and physician interaction/errors and omissions components of the milestone examinations. Conclusion. Results from milestone examinations can be used to identify specific areas in which curricular improvements are needed to foster student achievement of learning outcomes and professional competencies.

    The vulnerability of recently burned areas to debris flows has been well established. Likewise, it has been shown that many, if not most, post-fire debris flows are initiated by runoff and erosion and grow in size through erosion and scour by the moving debris flow, as opposed to landslide-initiated flows with little growth. To better understand the development and character of these flows, a study has been completed encompassing 46 debris flows in California, Utah, and Colorado, in nine different recently burned areas. For each debris flow, progressive debris production was measured at intervals along the length of the channel, and from these measurements graphs were developed showing cumulative volume of debris as a function of channel length. All 46 debris flows showed significant bulking by scour and erosion, with average yield rates for each channel ranging from 0.3 to 9.9??m3 of debris produced for every meter of channel length, with an overall average value of 2.5??m3/m. Significant increases in yield rate partway down the channel were identified in 87% of the channels, with an average of a three-fold increase in yield rate. Yield rates for short reaches of channels (up to several hundred meters) ranged as high as 22.3??m3/m. Debris was contributed from side channels into the main channels for 54% of the flows, with an average of 23% of the total debris coming from those side channels. Rill erosion was identified for 30% of the flows, with rills contributing between 0.1 and 10.5% of the total debris, with an average of 3%. Debris was deposited as levees in 87% of the flows, with most of the deposition occurring in the lower part of the basin. A median value of 10% of the total debris flow was deposited as levees for these cases, with a range from near zero to nearly 100%. These results show that channel erosion and scour are the dominant sources of debris in burned areas, with yield rates increasing significantly partway down the channel. Side channels are

    curricular areas so that they could be acquired and be developed from the transversality, permitting thus a greater approximation and contextualization with the reality of each student and with the conflicts and problems of the contemporary world and, at the same time endowing them of an immediate functional value with respect to the comprehension and possible transformation of that reality and of those conflicts. In this sense the aspects that try to be incorporated are not something added, but yes novel from the moment in which is introduced a new perspective, and is avoided the risk, sometimes so mentioned, of the fact that the transversality appear subtly blurred. The transverse shafts under this new position will imply an important transformation of the curricular areas according to the expectations of the present times and the appropriateness to the possibilities of comprehension of the student. This will be thus, if the transverse approaches, that constitute the center of the current social preoccupations of the curricular areas, are converted into the kernel in connection with those which turns the programming of the curricular areas, those which will be converted then in the necessary instruments for the attainment of the wished purposes.

    Objective. To identify ways in which curricular integration is addressed in US pharmacy schools, the structure of therapeutics and foundational science courses, and perceptions of the effects current curricular integration methods have on student learning. Methods. An electronic survey was sent to academic leaders representing 131 pharmacy schools in the United States. Frequency data was tabulated and demographic analysis was performed. Results. Respondent data represents 94 schools of pharmacy. Arranging similar content from various disciplines in a course, a skills laboratory and pharmacy practice experiences were the most common methods for achieving curricular integration. More than one half of the schools indicated that foundational sciences were integrated with therapeutics. The most common reported challenge to curricular integration was logistics. Conclusion. Pharmacy education in the United States has evolved in addressing curricular integration in the curricula, which is consistent with changes in accreditation standards. Most pharmacy schools reported a variety of methods for achieving the intent of curricular integration.

    We developed a prototype instrument called the Standoff Biofinder, which can quickly locate biological material in a 500 cm2 area from a 2 m standoff distance with a detection time of 0.1 s. All biogenic materials give strong fluorescence signals when excited with UV and visible lasers. In addition, the luminescence decay time of biogenic compounds is much shorter (biofluorescent materials to obtain real-time fluorescence images that show the locations of biological materials among luminescent minerals in a geological context. The Standoff Biofinder instrument will be useful for locating biological material during future NASA rover, lander, and crewed missions. Additionally, the instrument can be used for nondestructive detection of biological materials in unique samples, such as those obtained by sample return missions from the outer planets and asteroids. The Standoff Biofinder also has the capacity to detect microbes and bacteria on space instruments for planetary protection purposes.

Os Parâmetros Curriculares Nacionais (PCNs orientam a promoção de concepções de saúde de modo transversal no currículo escolar. Este estudo teve como objetivo identificar e analisar a abordagem dos temas alimentação e nutrição no material didático do ensino fundamental e sua interface com o conceito de SAN e com os PCNs. Foi realizada pesquisa documental mediante o material didático de 5ª a 8ª séries do ensino fundamental da rede pública do Estado de São Paulo. A presença difusa do tema alimentação e nutrição na maioria das disciplinas, por todos os bimestres, nas quatro séries, traz à tona a interdisciplinaridade em saúde. Verificou-se que os PCNs estão relacionados ao conceito de SAN nos seus diversos aspectos e que a maioria das disciplinas contém temas que abordam esta relação. Na interface entre os temas, destaca-se a promoção da saúde e a produção dos alimentos. A metodologia utilizada no material didático apresenta o tema, mas não o conteúdo correlato, o que impossibilitou a análise de sua adequação. Conclui-se que existe a abordagem dos temas relacionados à alimentação e nutrição no material didático, alguns de forma inconsistente, e cabe aos educadores a seleção do conteúdo e da estratégia adequada, além de sua constante atualização, o que está sendo proposto pelo Estado, mas não está ao alcance de todos os profissionais e, portanto, ainda depende da iniciativa de cada docente.Food and Nutrition Security (FNS must be ensured to everybody.

    The common marmoset (Callithrix jacchus) is one of the smallest species of primates, with high visual recognition abilities that allow them to judge the identity and quality of food and objects in their environment. To address the cortical processing of visual information related to material surface features in marmosets, we presented a set of stimuli that have identical three-dimensional shapes (bone, torus or amorphous) but different material appearances (ceramic, glass, fur, leather, metal, stone, wood, or matte) to anesthetized marmoset, and recorded multiunit activities from an area ventral to the superior temporal sulcus (STS) using multi-shanked, and depth resolved multi-electrode array. Out of 143 visually responsive multiunits recorded from four animals, 29% had significant main effect only of the material, 3% only of the shape and 43% of both the material and the shape. Furthermore, we found neuronal cluster(s), in which most cells: (1) showed a significant main effect in material appearance; (2) the best stimulus was a glossy material (glass or metal); and (3) had reduced response to the pixel-shuffled version of the glossy material images. The location of the gloss-selective area was in agreement with previous macaque studies, showing activation in the ventral bank of STS. Our results suggest that perception of gloss is an important ability preserved across wide range of primate species.

    Socioeconomic inequalities affecting health are of major importance in Europe. The literature enhances the role of social determinants of health, such as socioeconomic characteristics and urbanization, to achieve health equity. Yet, there is still much to know, mainly concerning the association between cause-specific mortality and several social determinants, especially in metropolitan areas. This study aims to describe the geographical pattern of cause-specific mortality in the Lisbon Metropolitan Area (LMA), at small area level (parishes), and analyses the statistical association between mortality risk and health determinants (material deprivation and urbanization level). Fourteen causes have been selected, representing almost 60% of total mortality between 1995 and 2008, particularly those associated with urbanization and material deprivation. A cross-sectional ecological study was carried out. Using a hierarchical Bayesian spatial model, we estimated sex-specific smoothed Standardized Mortality Ratios (sSMR) and measured the relative risks (RR), and 95% credible intervals, for cause-specific mortality relative to 1. urbanization level, 2. material deprivation and 3. material deprivation adjusted by urbanization. The statistical association between mortality and material deprivation and between mortality and urbanization changes by cause of death and sex. Dementia and MN larynx, trachea, bronchus and lung are the causes of death showing higher relative risk associated with urbanization. Infectious and parasitic diseases, Chronic liver disease and Diabetes are the causes of death presenting higher relative risk associated with material deprivation. Ischemic heart disease was the only cause with a statistical association with both determinants, and MN female breast was the only without any statistical association. Urbanization level reduces the impact of material deprivation for most of the causes of death. Men face a higher impact of material deprivation and

    2015-07-01

    Beginning in the 2014-2015 training year, the US Accreditation Council for Graduate Medical Education (ACGME) required that nephrology Clinical Competency Committees assess fellows' progress toward 23 subcompetency "context nonspecific" internal medicine subspecialty milestones. Fellows' advancement toward the "ready for unsupervised practice" target milestone now is tracked in each of the 6 competencies: Patient Care, Medical Knowledge, Professionalism, Interpersonal Communication Skills, Practice-Based Learning and Improvement, and Systems-Based Practice. Nephrology program directors and subspecialty societies must define nephrology-specific "curricular milestones," mapped to the nonspecific ACGME milestones. Although the ACGME goal is to produce data that can discriminate between successful and underperforming training programs, the approach is at risk to produce biased, inaccurate, and unhelpful information. We map the ACGME internal medicine subspecialty milestones to our previously published nephrology-specific milestone schema and describe entrustable professional activities and other objective assessment tools that inform milestone decisions. Mapping our schema onto the ACGME subspecialty milestone reporting form allows comparison with the ACGME subspecialty milestones and the curricular milestones developed by the American Society of Nephrology Program Directors. Clinical Competency Committees may easily adapt and directly translate milestone decisions reached using our schema onto the ACGME internal medicine subspecialty competency milestone-reporting format.

    2016-10-01

    An exploratory, cross-sectional survey design was used to explore the extent to which CAM was included, what factors impacted its inclusion, topics and student learning outcomes covered, who taught the material, and what sources were used to prepare for delivering course content. While the vast majority of responding occupational therapy educators reported curricular inclusion of CAM, educational experiences for occupational therapy students varied widely. This overview of the curricular inclusion of CAM by faculty in occupational therapy programs in the United States indicated that many occupational therapy educators are responding to the demands of a more integrative healthcare system. Resolving ethical and pragmatic issues, providing faculty development opportunities, and standardizing student learning outcomes would align all stakeholders and mitigate ambiguities that currently exist surrounding the inclusion of CAM in occupational therapy education.

Tests and analyses were conducted according to the manual developed by the USACE and the U.S. Environmental Protection Agency (EPA), Evaluation of Dredged Material Proposed for Ocean Disposal (Testing Manual), commonly referred to as the {open_quotes}Green Book,{close_quotes} and the regional manual developed by the USACE-NYD and EPA Region II, Guidance for Performing Tests on Dredged Material to be Disposed of in Ocean Waters. The reevaluation of proposed dredged material from the Arthur Kill project areas consisted of benthic acute toxicity tests. Thirty-three individual sediment core samples were collected from the Arthur Kill project area. Three composite sediments, representing each reach of the area proposed for dredging, was used in benthic acute toxicity testing. Benthic acute toxicity tests were performed with the amphipod Ampelisca abdita and the mysid Mysidopsis bahia. The amphipod and mysid benthic toxicity test procedures followed EPA guidance for reduction of total ammonia concentrations in test systems prior to test initiation. Statistically significant acute toxicity was found in all Arthur Kill composites in the static renewal tests with A. abdita, but not in the static tests with M. bahia. Statistically significant acute toxicity and a greater than 20% increase in mortality over the reference sediment was found in the static renewal tests with A. abdita. M. bahia did not show statistically significant acute toxicity or a greater than 10% increase in mortality over reference sediment in static tests. 5 refs., 2 figs., 2 tabs.

    Acoustic lenses made of acrylic plastic (PMMA) have been used to enlarge the acceptance angle of sensitive large surface area detectors and improve lateral resolution. However, PMMA lenses introduce image artifacts due to ultrasound internal reflections within the lenses. In this work we investigated this issue proposing a new lens material Stycast 1090SI. We characterized the acoustic properties of the proposed material in comparison with PMMA. Detector performance using negative lenses with the two materials, was tested using finite element simulation and experiment. Further the image quality of a photoacoustic tomography system was studied using k-Wave simulation and experiment. Our acoustic characterization showed that Stycast 1090SI has tissue-like acoustic impedance, high speed of sound and low acoustic attenuation. Both acoustic lenses show significant enlargement of detector acceptance angle and lateral resolution improvement. However, image artifacts induced by acoustic lenses are reduced using the p...

    Highlights: • Porous MgO material with ultrahigh surface area was synthesized. • A composite PCM was prepared from PEG-1000 and the porous MgO. • The phase change temperatures and enthalpy of the composite were measured. • The composite PCM performed good shape-stabilized property. - Abstract: Mesoporous magnesium oxide (MgO) material was synthesized using an integration of the evaporation-induced surfactant assembly and magnesium nitrate pyrolysis. The as-prepared MgO material is well crystalline, and possesses three-dimensional interconnected mesopores and a surface area as high as 596 m{sup 2}/g. Using the porous MgO as a matrix and polyethylene glycol (PEG-1000) as the functional phase for heat energy storage, a shape-stabilized phase change composite of PEG/MgO was fabricated by an easy impregnation method. In the composite, mesoporous MgO material provides structural strength and prevents the leakage of the molten PEG during the phase change process. The compositions and microstructures of the PEG/MgO composite were determined by Fourier transformation infrared spectroscope (FT-IR), X-ray diffractometer (XRD), scanning electronic microscope (SEM) and thermogravimetric analyzer (TGA), respectively. The phase change properties of the PEG/MgO composite were determined by differential scanning calorimeter (DSC). The high heat-energy storage capability and good thermal stability of the composite enable it extensive applications in the future.

    The challenges of producing and distributing the food necessary to feed an anticipated 9 billion people in developed and developing societies by 2050 without destroying Earth's finite soil and water resources present extremely complex problems that lack simple solutions. The ability of modern societies to adequately address these and other food-related problems will require an educated workforce trained not only in traditional food safety, security, and public health, but also in other areas including food production, sustainable practices, and ecosystem health. To help address the need for such an educated workforce, a curricular framework was developed to assist those tasked with designing education and training for future food systems workers. One sentence summary: A curricular framework for education and training in food safety and security was developed that incorporates One Health concepts.

    The objective of the Westchester Creek project was to evaluate proposed dredged material from this area to determine its suitability for unconfined ocean disposal at the Mud Dump Site. Westchester Creek was one of five waterways that the US Army Corps of Engineers- New York District (USACE-NYD) requested the Battelle/Marine Sciences Laboratory (MSL) to sample and evaluate for dredging and disposal in May 1995. The evaluation of proposed dredged material from the Westchester Creek project area consisted of bulk sediment chemical analyses, chemical analyses of dredging site water and elutriate, benthic acute and water-column toxicity tests, and bioaccumulation studies. Thirteen individual sediment core samples were collected from this area and analyzed for grain size, moisture content, and total organic carbon (TOC). One composite sediment sample representing the Westchester Creek area to be dredged, was analyzed for bulk density, specific gravity, metals, chlorinated pesticides, polychlorinated biphenyl (PCB) congeners, polynuclear aromatic hydrocarbons (PAHs), and 1,4-dichlorobenzene. Dredging site water and elutriate water, which is prepared from the suspended- particulate phase (SPP) of the Westchester Creek sediment composite, was analyzed for metals, pesticides, and PCBS.

  9. MINIMUM SOLID AREA MODELS FOR THE EFFECTIVE PROPERTIES OF POROUS MATERIALS - A REFUTATION

    Directory of Open Access Journals (Sweden)

    Willi Pabst

    2015-09-01

    Full Text Available Minimum solid area (MSA models are popular models for the calculation of the effective properties of porous materials and are frequently used to justify the use of a simple exponential relation for fitting purposes. In this contribution it is shown that MSA models, and the simple exponentials they support, are misleading and should be avoided. In particular, taking Young modulus and conductivity (thermal or electrical as examples, it is shown that MSA models are based on the unjustified (and unjustifiable hypothesis that the relative Young modulus and relative conductivity are identical, and moreover equal to the MSA fraction itself. This claim is generally false for isotropic materials, both random or periodic. Although indeed a very specific case exists in which this claim is true for the properties in one specific direction (viz., extremely anisotropic materials with translational invariance, in this specific case MSA models are redundant, because the relative properties are given exactly by the volume- or area-weighted arithmetic mean. It is shown that the mere existence of non-trivial cross-property relations is incompatible with the existence of MSA models. Finally, it is shown by numerical (finite-element modeling that MSA models provide incorrect results even in the simplest of the cases for which they were originally designed, i.e. for simple cubic packings of partially sintered isometric (initially spherical grains. Therefore, paraphrasing Box, MSA models are not only wrong, but also useless, and should be abandoned.

    This study evaluated the effect of retentive areas on onlay preparations on the dimensional alterations in condensation and addition silicone materials. A standard model with an onlay preparation was made. Each impression material was used through the double or simultaneous impression technique (n=25), resulting in a hundred impressions of the same model. Impressions were poured with type IV dental stone. Digital images were taken with a light microscope and the distances between the reference points created on the plaster dies were compared with the ones on the standard model. In the occlusal, mesial-medium and mesial-cervical segments, the double impression (DI) with condensation silicone presented similar values compared to the standard model. The values of the addition silicone with DI were similar to the standard model only in the mesial-occlusal segment. In the other segments (distal-cervical, distal-medium and distal-occlusal), all groups were statistically different from the control. It could be concluded that addition and condensation silicone impressions provided plaster dies with significant dimensional alterations in most of the evaluated areas when compared to the standard model. The retentive areas related to the onlay preparation influenced the dimensional stability of the addition and condensation silicone impressions.

    A preliminary investigation of possible sources of cement rock in the Taft area was made during the latter part of August 1968. Adequate deposits of limestone, clay, quartz conglomerate and sandstone, and pisolitic iron ore, yet no gypsum, were located to support a Cement plant should it prove feasible to establish one in this area. These materials, made up mostly of Tertiary and later sediments, crop out in isolated, inconspicuous low hills in a north- trending belt, 10 to 15 kilometers wide, lying about 90 kilometers to-the east of At Taft. The belt extends for more than 90 kilometers from the vicinity of Jabal 'An in the south to the crushed rock pits at Radwan and beyond in the north. The area is readily accessible either from the Talf-Riyadh highway or from the Taif-Bishah road presently under construction. The limestone, which is quite pure and dense in some localities but dolomitic, argillaceous, and cherty in others, occurs in a variety of colors and would make suitable decorative building stone. The volcanic rocks of the Harrat Hadan, lying directly to the east of the limestone belt, include volcanic ash beds some of which may have been altered to bentonitlc clays. Others may have been lithified and might be suitable for light-weight aggregate. These possibilities remain to be investigated. Precambrian metamorphic rocks lying directly to the south and southeast of Taif were also investigated as possible cement rock sources, but no suitable material was found here.

    The objective of the Eastchester project (Federal Project [FP] No. 6) was to evaluate proposed dredged material from the Eastchester project area in the Hutchinson River to determine its suitability for unconfined ocean disposal at the Mud Dump Site. Eastchester was one of seven waterways that the U. S. Army Corps of Engineers-New York District (USACE-NYD) requested the Battelle/Marine Sciences Laboratory (MSL) to sample and evaluate for dredging and disposal in March 1994. The evaluation of proposed dredged material from the Eastchester project area consisted of bulk sediment chemical analyses, chemical analyses of dredging site water and elutriate, water- column and benthic acute toxicity tests, and bioaccumulation studies. Eighteen individual sediment core samples collected from the Eastchester project area were analyzed for grain size, moisture content, and total organic carbon (TOC). Two composite sediment samples, representing the upstream and lower reaches of the area proposed for dredging, were analyzed for bulk density, specific gravity, metals, chlorinated pesticides, polychlorinated biphenyl (PCB) congeners, polynuclear aromatic hydrocarbons (PAHs), and 1,4- dichlorobenzene. Dredging site water and elutriate water, which is prepared from the suspended-particulate phase (SPP) of the two Eastchester sediment composites, were analyzed for metals, pesticides, and PCBS. An additional 1 1 composite samples were created for the USACE-New England Division (USACE-NED) using the same 18 Eastchester core samples but combined into different composites. These composites were analyzed for metals, chlorinated pesticides, PCB congeners, PAHS, and 1,4-dichlorobenzene. Water-column or SPP toxicity tests were performed along with bioaccumulation tests.

    Full Text Available the course of this research, we explored the extent of chemistry teachers’ professional knowledge related to the structure, contents and application of chemistry curricula and their components. The research comprised 119 teachers from 69 secondary schools (25 grammar schools and 44 vocational secondary schools. The questions in the questionnaire referred to general curriculum knowledge, knowledge of chemistry curriculum and the views/assessments of teachers concerning the necessary changes in the curricula currently in effect. The teachers’ answers show that the most important components of the curriculum for their work are the goals and operative tasks/outcomes. The results indicate that there exists information in the curriculum components that remains unused although it is relevant for a certain level of planning. Among the teachers in the sample, higher percentages of those with appropriate teachers training programme were applying information from the curriculum within teaching process through demonstration method and problem solving. The research that was conducted provides a basis for defining the indicators for monitoring the level of teachers’ capability to apply curricular knowledge in their practice. Such indicators are important for creating teaching situations and teachers’ activities within the framework of initial teacher education and continuing professional development.

  4. Controlling Structure and Properties of High Surface Area Nonwoven Materials via Hydroentangling

    Science.gov (United States)

    Luzius, Dennis

    Hydroentangling describes a technique using a series of high-velocity water jets to mechanically interlock and entangle fibers. Over the last decades researchers worked on a fundamental understanding of the process and the factors influencing the properties of the final nonwoven material. Recent studies discovered hydroentangling to be capable to create unique, knot-like structures characterized by high- and low density regions, which are believed to have interesting properties for filtration applications. However, just little is known about the impact of hydroentangling parameters on the properties of filtration media to this day. In this study we report on the effect of various hydroentangling parameters, such as jet spacing, manifold pressure, number of manifolds but also specific energy on the structure and properties of high surface area nonwoven materials. Latter was achieved by different bicomponent fiber technologies and subsequent treatments removing the sacrificial compound from the structure. The highest BET surface area was measured to be 3.5 m2 g-1 and the smallest mean fiber size about 0.5 mum. Hydroentangling with large jet spacing was found to be a parameter significantly enhancing the filtration properties of caustic-treated island-in-the-sea nonwoven materials. Moreover, improved capture efficiencies and reduced pressure drops were achieved by reducing the manifold pressure and therefore specific energy during hydroentangling. Jet spacing but not island count was found to be the dominant factor influencing the structure and properties of island-in-the-sea nonwovens. Contrary to our initial expectations increasing the island count and thus decreasing the fiber size did not result in better filtration properties. Mixed media nonwoven structures made from homocomponent and island-in-the-sea fibers were found to have lower densities, higher air permeabilities and better quality factors compared to island-in-the-sea structures hydroentangled under the

    We report a method to obtain the stress of crystalline materials directly from lattice deformation by Hooke's law. The lattice deformation was calculated using the crystallographic orientations obtained from electron backscatter diffraction (EBSD) technology. The stress distribution over a large area was obtained efficiently and accurately using this method. Wurtzite structure gallium nitride (GaN) crystal was used as the example of a hexagonal crystal system. With this method, the stress distribution of a GaN crystal was obtained. Raman spectroscopy was used to verify the stress distribution. The cause of the stress distribution found in the GaN crystal was discussed from theoretical analysis and EBSD data. Other properties related to lattice deformation, such as piezoelectricity, can also be analyzed by this novel approach based on EBSD data.

  20. Lessons from industry: one school's transformation toward "lean" curricular governance.

    Stratton, Terry D; Rudy, David W; Sauer, Marlene J; Perman, Jay A; Jennings, C Darrell

    2007-04-01

    As medical education grapples with organizational calls for centralized curricular oversight, programs may be compelled to respond by establishing highly vertical, stacked governance structures. Although these models offer discrete advantages over the horizontal, compartmentalized structures they are designed to replace, they pose new challenges to ensuring curricular quality and the educational innovations that drive the curricula. The authors describe a hybrid quality-assurance (QA) governance structure introduced in 2003 at the University of Kentucky College of Medicine (UKCOM) that ensures centralized curricular oversight of the educational product while allowing individualized creative control over the educational process. Based on a Lean production model, this approach draws on industry experiences that strategically separate institutional accountability (management) for a quality curriculum from the decision-making processes required to ensure it (production). In so doing, the authors acknowledge general similarities and key differences between overseeing the manufacture of a complex product versus the education of a physician-emphasizing the structured, sequential, and measurable nature of each process. Further, the authors briefly trace the emergence of quality approaches in manufacturing and discuss the philosophical changes that accompany transition to an institutional governance system that relies on vigorous, robust performance measures to offer continuous feedback on curricular quality.

  5. PROPERTIES AND MANAGEMENT IMPLICATIONS OF SOILS FORMED FROM VOLCANIC MATERIALS IN LEMBANG AREA, WEST JAVA

    Directory of Open Access Journals (Sweden)

    Edi Yatno

    2016-10-01

    Full Text Available Soils formed from volcanic materials have a high potential for agricultural development, especially for horticultural crops, tea, and pine trees. Data on the characteristics of these soils are important for the management planning. Six representative soil profiles developed on andesitic volcanic ash and tuff in Lembang area, West Java were studied to determine the soil physical, chemical, and mineralogical properties, to study the relationship between the soil properties, and to classify the soils according to the Soil Taxonomy. The results indicated that all the soils had very deep (>150 cm solum. In general, the volcanic ash soils were darker colored, more granular, more friable, less sticky and less plastic than the volcanic tuff soils. Physically, the ash soils had lower bulk density (0.44-0.73 mg m-3 and higher available water content (13-33% than the tuff soils. Bulk density decreased with increasing allophane. Chemically, the ash soils had higher pHNaF (mostly > 10, higher organic carbon (4.3-6.8% in upper horizons, higher CEC (20- 44 cmolc kg-1, and higher P retention (> 85% than the tuff soils. P retention logarithmically increased with increasing oxalate extractable Al and allophane. The sand fractions of the ash soils were dominated by hornblende, while the tuff soils were predominantly composed of opaque minerals. In the clay fractions, the ash soils were dominated by allophane, whereas the tuff soils showed high contents of gibbsite and metahalloysite. Soils developed on volcanic ash were classified as Thaptic Hapludands and Typic Melanudands, while soils formed from volcanic tuff were classified as Andic Dystrudepts. The low bulk density and friable consistency of the soils contributed to favorable soil tilth. However, high P retention and Al saturation in most soils are limiting factors for plant growth. Application of P fertilizers and liming coupled with efficient placement can be recommended to enhance P availability and

  7. From microporous regular frameworks to mesoporous materials with ultrahigh surface area: dynamic reorganization of porous polymer networks.

    Science.gov (United States)

    Kuhn, Pierre; Forget, Aurélien; Su, Dangsheng; Thomas, Arne; Antonietti, Markus

    2008-10-08

    High surface area organic materials featuring both micro- and mesopores were synthesized under ionothermal conditions via the formation of polyaryltriazine networks. While the polytrimerization of nitriles in zinc chloride at 400 degrees C produces microporous polymers, higher reaction temperatures induce the formation of additional spherical mesopores with a narrow dispersity. The nitrogen-rich carbonaceous polymer materials thus obtained present surface areas and porosities up to 3300 m(2) g(-1) and 2.4 cm(3) g(-1), respectively. The key point of this synthesis relies on the occurrence of several high temperature polymerization reactions, where irreversible carbonization reactions coupled with the reversible trimerization of nitriles allow the reorganization of the dynamic triazine network. The ZnCl2 molten salt fulfills the requirement of a high temperature solvent, but is also required as catalyst. Thus, this dynamic polymerization system provides not only highly micro- and mesoporous materials, but also allows controlling the pore structure in amorphous organic materials.

    This study recruited 16 industrial workers to examine the effects of material, weight, and base area of container on reduction of grip force (ΔGF) and heart rate for a 100-m manual carrying task. This study examined 2 carrying materials (iron and water), 4 carrying weights (4.4, 8.9, 13.3, 17.8 kg), and 2 base areas of container (24 × 24 cm, 35 × 24 cm). This study showed that carrying water significantly increased ΔGF and heart rate as compared with carrying iron. Also, ΔGF and heart rate significantly increased with carrying weight and base area of container. The effects of base area of container on ΔGF and heart rate were greater in carrying water condition than in carrying iron condition. The maximum dynamic effect of water on ΔGF and heart rate occurred when water occupied ~60%-80% of full volume of the container.

    2014-11-15

    No published curricula in the area of medical business ethics exist. This is surprising given that physicians wrestle daily with business decisions and that professional associations, the Institute of Medicine, Health and Human Services, Congress, and industry have issued related guidelines over the past 5 years. To fill this gap, the authors aimed (1) to identify the full range of medical business ethics topics that experts consider important to teach, and (2) to establish curricular priorities through expert consensus. In spring 2012, the authors conducted an online Delphi survey with two heterogeneous panels of experts recruited in the United States. One panel focused on business ethics in medical practice (n = 14), and 1 focused on business ethics in medical research (n = 12). Panel 1 generated an initial list of 14 major topics related to business ethics in medical practice, and subsequently rated 6 topics as very important or essential to teach. Panel 2 generated an initial list of 10 major topics related to business ethics in medical research, and subsequently rated 5 as very important or essential. In both domains, the panel strongly recommended addressing problems that conflicts of interest can cause, legal guidelines, and the goals or ideals of the profession. The Bander Center for Medical Business Ethics at Saint Louis University will use the results of the Delphi panel to develop online curricular resources for each of the highest rated topics.

    Forquin, Pascal

    2017-01-01

    Brittle materials are extensively used in many civil and military applications involving high-strain-rate loadings such as: blasting or percussive drilling of rocks, ballistic impact against ceramic armour or transparent windshields, plastic explosives used to damage or destroy concrete structures, soft or hard impacts against concrete structures and so on. With all of these applications, brittle materials are subjected to intense loadings characterized by medium to extremely high strain rates (few tens to several tens of thousands per second) leading to extreme and/or specific damage modes such as multiple fragmentation, dynamic cracking, pore collapse, shearing, mode II fracturing and/or microplasticity mechanisms in the material. Additionally, brittle materials exhibit complex features such as a strong strain-rate sensitivity and confining pressure sensitivity that justify expending greater research efforts to understand these complex features. Currently, the most popular dynamic testing techniques used for this are based on the use of split Hopkinson pressure bar methodologies and/or plate-impact testing methods. However, these methods do have some critical limitations and drawbacks when used to investigate the behaviour of brittle materials at high loading rates. The present theme issue of Philosophical Transactions A provides an overview of the latest experimental methods and numerical tools that are currently being developed to investigate the behaviour of brittle materials at high loading rates. This article is part of the themed issue 'Experimental testing and modelling of brittle materials at high strain rates'.

    To overcome certain limitations of contemporary materials used for bone tissue engineering, such as inflammatory response after implantation, a whole new class of materials based on polysaccharide compounds is being developed. Here, nanoparticulate bioactive glass reinforced gelan-gum (GG-BAG) has recently been proposed for the production of bone scaffolds. This material offers promising biocompatibility properties, including bioactivity and biodegradability, with the possibility of producing scaffolds with directly controlled microgeometry. However, to utilize such a scaffold with application-optimized properties, large sets of complex numerical simulations using the real microgeometry of the material have to be carried out during the development process. Because the GG-BAG is a material with intrinsically very low attenuation to X-rays, its radiographical imaging, including tomographical scanning and reconstructions, with resolution required by numerical simulations might be a very challenging task. In this paper, we present a study on X-ray imaging of GG-BAG samples. High-resolution volumetric images of investigated specimens were generated on the basis of micro-CT measurements using a large area flat-panel detector and a large area photon-counting detector. The photon-counting detector was composed of a 010× 1 matrix of Timepix edgeless silicon pixelated detectors with tiling based on overlaying rows (i.e. assembled so that no gap is present between individual rows of detectors). We compare the results from both detectors with the scanning electron microscopy on selected slices in transversal plane. It has been shown that the photon counting detector can provide approx. 3× better resolution of the details in low-attenuating materials than the integrating flat panel detectors. We demonstrate that employment of a large area photon counting detector is a good choice for imaging of low attenuating materials with the resolution sufficient for numerical simulations.

    Vital pulp therapy involves biologically based therapeutic activities aimed at restoring health and preserving the vitality of cariously or traumatically damaged pulp. Adaptation of pulp-capping materials to the prepared tooth surface may be the key to the success of biological tooth treatment. To investigate the area of adaptation of synthetic tricalcium silicate cement, calcium hydroxide cement and mineral trioxide-aggregate to the dentin surface, prepared with the help of Er:YAG dental laser. Four extracted human tooth cavities were prepared with the help of Er:YAG dental laser (LiteTouch, Syneron, Israel), establishing microcommunication with the pulp chamber less than 1 mm in diameter. As pulp-capping materials in the cavities we used tricalcium silicate cement (Biodentine, Septodont, France), calcium hydroxide cement (Dycal) and mineral-trioxide aggregate (ProRoot MTA), stirred and administered according to manufacturers' instructions. The first material fills the whole cavity and the other two are spread in a thin layer and sealed with glass ionomer cement. Thus prepared, the samples were left for three days at 37°C in humidified environment. The samples were prepared for scanning electron microscopy (SEM) by standard methodology. The border area surfaces of the materials and the dentin were scanned using electron microscopy. The morphological changes occurring to the Er:YAG laser prepared dentin and the structural characteristics of the studied pulp-capping materials are demonstrated using scanograms. The border areas where good contact of materials and dentinal tubules is established are thoroughly studied. Good adaptation is seen in three-calcium silicate cement, followed by mineral trioxide aggregate and calcium hydroxide cement. The dentin surface, prepared with Er:YAG laser demonstrates a very good adaptation of the three tested pulp-capping materials.

    Amongst several exploratory sources of the subject 'hazardous materials transport', it is distinguished: 'the threat to the environment'. This paper presents an exploratory investigation of this subject line in the Amazon region. In view of the diversity of 'existing hazardous materials' and the raised dimension of the oil transport and its derivatives in this context, this paper focused in these products. Regarding to the geographic region, the approach was given to the State of Amazon, considering the amplitude of this State in the Amazon region and the availability of data. Therefore, this work explores and analyzes macro aspects inherent to the State of Amazon pertinent to the oil transport and its derivatives. In the macro context, it is observed the necessity of a higher control in the transport of hazardous materials in the region. The absence of registered data and the unfamiliarity on the risks related to the transport of hazardous materials by authorities and transporters indicate a relative absence of qualification in the region to deal with the monitoring of the transport of hazardous materials. So far, it is not possible up till now to make any evaluation of the environment threats of accidents with transport of hazardous materials in the Amazon region.(author)

    INTRODUCTION An assessment of known and undiscovered mineral resources of selected areas administered by the Bureau of Land Management (BLM) in Clark and Nye Counties, Nevada was conducted by the U.S. Geological Survey (USGS), Nevada Bureau of Mines and Geology (NBMG), and University of Nevada, Las Vegas (UNLV). The purpose of this work was to provide the BLM with information for use in their long-term planning process in southern Nevada so that they can make better-informed decisions. The results of the assessment are in Ludington (2006). Existing information about the areas, including geology, geophysics, geochemistry, and mineral-deposit information was compiled, and field examinations of selected areas and mineral occurrences was conducted. This information was used to determine the geologic setting, metallogenic characteristics, and mineral potential of the areas. Twenty-five Areas of Critical Environmental Concern (ACECs) were identified by BLM as the object of this study. They range from tiny (less than one km2) to large (more than 1,000 km2). The location of the study areas is shown on Figure 1. This report includes geochemical data for rock samples collected by staff of the USGS and NBMG in these ACECs and nearby areas. Samples have been analyzed from the Big Dune, Ash Meadows, Arden, Desert Tortoise Conservation Center, Coyote Springs Valley, Mormon Mesa, Virgin Mountains, Gold Butte A and B, Whitney Pockets, Rainbow Gardens, River Mountains, and Piute-Eldorado Valley ACECs.

    educativa.ABSTRACT: This paper presents some of the most relevant results from a study carried out in the Department of Didactics and School Organisation of the University of Santiago de Compostela analysing the perception of Primary School teachers regarding the printed curricular materials developed to aid in their teaching activities in the context of the educational reform. With this in mind we carried out a descriptive study in the province of A Coruña. An opinión survey was applied with a sample of 383 teachers from public schools, prívate schools, concertado (schools with public financing and escuelas unitarias (small schools often having only one teacher and located in rural áreas.The dimensions studied were the following: level of awareness regarding normative documents, adequacy of the new printed curricular materials: characteristics and use of the printed curricular materials; teacher training regarding these curricular materials and activities carried out in schools regarding curricular materials.This study also includes recommendations regarding measures which we believe should be taken by the institutions and professionals involved in the process of design, selection and utilisation of curricular materials. These recommendations are based on the assessments, analyses, and considerations expressed by the teachers in our study.Before discussing the results of our research, we will briefly present some of what we consider to be the main aspects characterising the relationship of teachers with curricular materials, which together with teacher training is among the most important support measures available to carry out the educational reform. The reason for our doing so is to reveal some of the reasons behind the decisión to study -through teachers' opinions- the role of curricular materials in the development of the educational reform.RÉSUMÉ: Dans cet article nous présentons quelques des resultáis les plus remarquables d'une recherche réalisée dans le

    non-covalent approach to functionalizing nanostructured materials with high-specificity ligands is described. In this work a variety of thiol ligands were non-covalently attached to self-assembled phenyl monolayers on nanostructured materials by taking advantage of favorable aromatic interactions. The resulting sorbent materials, both mesoporous silica and magnetic nanoparticles, were found to be very effective at scavenging soft heavy metal cations, Cd(II), Hg(II), Pb(II) and Ag(I), from aqueous matrices, performing better than commercial sorbents and comparably to the best covalently functionalized thiol sorbents available. This approach can be extended to a variety of surface chemistries and has application to chemical functionalization of a broad range of support structures used for chemical separations and processing.

    Building materials, collected from different sites in Ramsar, a northern coastal city in Iran, were analyzed for their natural radionuclide contents. The measurements were carried out using a high resolution high purity Germanium (HPGe) gamma-ray spectrometer system. The activity concentration of (226)Ra, (232)Th, and (40)K content varied from below the minimum detection limit up to 86,400 Bqkg(-1), 187 Bqkg(-1), and 1350 Bqkg(-1), respectively. The radiological hazards incurred from the use of these building materials were estimated through various radiation hazard indices. The result of this survey shows that values obtained for some samples are more than the internationally accepted maximum limits and as such, the use of them as a building material pose significant radiation hazard to individuals.

    Full Text Available Groundwaters hydrochemistry of Ayrakan and Cheshmeh Shotori areas and geochemistry of rare earth elements, indicate Ayrakan alkali granite as the origin of uranium and other dissolved elements in groundwaters of these areas. Geochemical and hydrogeochemical studies as well as the trend of uranium and thorium transition and mobility in aqueous environments of these areas indicate uranium adsorption by iron hydroxide (goethite as the deterrent agent against uranium transition and mobility from depth to surface. Gamma-ray spectroscopic study of sediments from Cheshmeh Shotori area by HPGe detector indicates the presence of 226Ra in high contents and as the radioactive nuclide that is the reason for high activity of these sediments. Production of 226Ra from 238U decay, shorter half-life of 226Ra compared to 238U, radium transition by groundwaters from depth to surface as well as hydrogeochemical evidences, all suggest the possibility of existence of hidden uranium deposit and uranium mineralization in depth and the distance between Ayrakan and Cheshmeh Shotori areas.

    The objective of the Shark River Project was to evaluate proposed dredged material to determine its suitability for unconfined ocean disposal at the Mud Dump Site. Tests and analyses were conducted on the Shark River sediments. The evaluation of proposed dredged material consisted of bulk sediment chemical and physical analysis, chemical analyses of dredging site water and elutriate, water-column and benthic acute toxicity tests, and bioaccumulation tests. Individual sediment core samples collected from the Shark River were analyzed for grain size, moisture content, and total organic carbon (TOC). One sediment composite was analyzed for bulk density, specific gravity, metals, chlorinated pesticides, polychlorinated biphenyl (PCB) congeners, polynuclear aromatic hydrocarbons (PAHs), and 1,4- dichlorobenzene. Dredging site water and elutriate, prepared from suspended-particulate phase (SPP) of the Shark River sediment composite, were analyzed for metals, pesticides, and PCBs. Benthic acute toxicity tests and bioaccumulation tests were performed.

    The dimensional stability of a thin intra sulcular impression material reproducing the preparation finish line was evaluated. Impressions were taken of a stainless-steel master model of a simulated abutment with a 'gingival sulcus' using Express regular, Express fast and Aquasil. The putty-wash two-step technique was applied with spacer thicknesses of 0.5, 1 and 1.5 mm. Mid mesiodistal and bucco-lingual measurements were taken directly from the sulcular impression material after 0.5, 2, 24, 48 and 72 h via a Toolmaker's microscope. The discrepancies between the measurements of the impression material and the master model were calculated. The discrepancies changed significantly over time (p<0.001). The use of a 0.5 mm spacer resulted in a negative deviation from the model (2-46 µm), minimally after 2 h. The use of 1 and 1.5 mm spacers showed a positive deviation from the model (21-52 µm) and both are equally recommended. Investment can be postponed until 72 h.

    Full Text Available The hanging mark is the most relevant feature of hanging and its characteristics are well known in the literature. Most of the time, the ligature material is not available during autopsy examination in hanging. Hence, the features of the ligature material are not submitted to systematic analysis. However, the type and position of the knot plays an important role in the mechanism of death and autopsy findings in hanging. Out of the total hanging deaths, complete hanging was seen in 67.7% of the cases, but a typical hanging was noted in only 10.2% of the cases. The commonest type of ligature material used for ligation around the neck was nylon rope followed by odhni and jute rope. The fixed knot was noted in 64.6% of the cases and a running (slip in 21.3% of the cases. The commonest position of the knot was at nape of the neck, followed by the left side of the neck at mastoid process. The number of turns/loops of a ligature around the neck was one turn in 72.4% and two in 25.2% the hanging deaths. Most victims committed suicide by hanging in their homes, and the commonest ligature points were trees, flowed by beams and ceiling hook/fans.

    2005-01-01

    This paper presents a synthesis process for preparing mesoporous titanium dioxide materials in the absence of any templates and using inorganic acids as catalysts. Tetrabutyl titanate was used as the precursor at ambient temperature, and four different inorganic acids, i.e., hydrochloric, nitric, sulfuric and phosphoric, were used as catalysts.The as-prepared mesoporous TiO2 materials were characterized by SEM, XRD and nitrogen adsorption/desorption measurements. The influences of different inorganic acids on the properties of TiO2 were discussed and compared in details. Experiments showed that the inorganic acids have significant effects on the surface area, pore volume, pore size,and pore size distribution of the products. The mesoporous TiO2 materials catalyzed by phosphoric acid exhibited the largest specific surface area and largest pore volume with narrow pore size distribution. Vacuum and infrared drying methods tested in the process were found to have subtle impact on the structure of the TiO2 materials prepared.

  15. E-Area Vault Concrete Material Property And Vault Durability/Degradation Projection Recommendations

    2014-03-11

    Subsequent to the 2008 E-Area Low-Level Waste Facility (ELLWF) Performance Assessment (PA) (WSRC 2008), two additional E-Area vault concrete property testing programs have been conducted (Dixon and Phifer 2010 and SIMCO 2011a) and two additional E-Area vault concrete durability modeling projections have been made (Langton 2009 and SIMCO 2012). All the information/data from these reports has been evaluated and consolidated herein by the Savannah River National Laboratory (SRNL) at the request of Solid Waste Management (SWM) to produce E-Area vault concrete hydraulic and physical property data and vault durability/degradation projection recommendations that are adequately justified for use within associated Special Analyses (SAs) and future PA updates. The Low Activity Waste (LAW) and Intermediate Level (IL) Vaults structural degradation predictions produced by Carey 2006 and Peregoy 2006, respectively, which were used as the basis for the 2008 ELLWF PA, remain valid based upon the results of the E-Area vault concrete durability simulations reported by Langton 2009 and those reported by SIMCO 2012. Therefore revised structural degradation predictions are not required so long as the mean thickness of the closure cap overlying the vaults is no greater than that assumed within Carey 2006 and Peregoy 2006. For the LAW Vault structural degradation prediction (Carey 2006), the mean thickness of the overlying closure cap was taken as nine feet. For the IL Vault structural degradation prediction (Peregoy 2006), the mean thickness of the overlying closure cap was taken as eight feet. The mean closure cap thicknesses as described here for both E-Area Vaults will be included as a key input and assumption (I&A) in the next revision to the closure plan for the ELLWF (Phifer et al. 2009). In addition, it has been identified as new input to the PA model to be assessed in the ongoing update to the new PA Information UDQE (Flach 2013). Once the UDQE is approved, the SWM Key I

    The objective of the Red HookIBay Ridge project was to evaluate proposed dredged material from these two areas to determine its suitability for unconfined ocean disposal at the Mud Dump Site. Sediment samples were collected from the Red Hook/Bay Ridge project areas. Tests and analyses were conducted. The evaluation of proposed dredged material from the Red Hook/Bay Ridge project areas consisted of bulk sediment chemical analyses, chemical analyses of dredging site water and elutriate, water-column and benthic acute toxicity tests. Twenty-four individual sediment core samples were collected from these two areas and analyzed for grain size, moisture content, and total organic carbon (TOC). Three composite sediment samples, representing Red Hook Channel and the two Bay Ridge Reaches to be dredged, were analyzed for bulk density, specific gravity, metals, chlorinated pesticides, polychlorinated biphenyl (PCB) congeners, polynuclear aromatic hydrocarbons (PAH), and 1,4-dichlorobenzene. Dredging site water and elutriate water, which is prepared from the suspended-particulate phase (SPP) of the three Red Hook Bay Ridge sediment composites, were analyzed for metals, pesticides, and PCBS. Benthic acute toxicity tests were performed. Water-column or SPP toxicity tests were performed. Bioaccumulation tests were also conducted.

    Full Text Available Any machine part is subject to degradation processes. Intensive wear occurs either when two bearing surfaces come into contact or when loose particles rub the function surface of a machine part. Soil processing machines are a good example. A similar process of abrasive wear occurs also in mixing machines or lines for material transport, such as worm-conveyors. The experiment part of this paper analyses hard metal weld deposit dedicated for renovation of abrasive stressed surfaces. In order to prolong the service life of a blade disc in a mixing machine Kreis-Biogas-Dissolver, the technology of hard surfacing by an electric arc was used. Tested hard metal electrodes were applied on a steel tape class 11 373. To eliminate mixing with the base material, weld beads were applied in two layers. Firstly, the weld bead was visually analyzed on a binocular microscope. Further, weld bead as well as the base material was analyzed from the metallographic point of view, whose aim was to identify the structure of weld metal and the origin of microcracks in weld bead. Moreover, there was also measured microhardness of weld metal. Abrasive resistance was tested according to the norm ČSN 01 5084, which is an abrasive cloth test. As in the mixing process also erosion wear occurs, there was also processed a test on a Bond device simulating stress of test samples by loose abrasive particles. The abrading agents were formed by broken stones of 8–16 mm in size. Based on the results of the individual tests, the recommendation of usage hard metal electrodes for prolonging service life of machine parts will be made.

    Large-area phosphorus-doped carbon nanosheets (P-CNSs) are first obtained from carbon dots (CDs) through self-assembly driving from thermal treatment with Na catalysis. This is the first time to realize the conversion from 0D CDs to 2D nanosheets doped with phosphorus. The sodium storage behavior of phosphorus-doped carbon material is also investigated for the first time. As anode material for sodium-ion batteries (SIBs), P-CNSs exhibit superb performances for electrochemical storage of sodium. When cycled at 0.1 A g(-1), the P-CNSs electrode delivers a high reversible capacity of 328 mAh g(-1), even at a high current density of 20 A g(-1), a considerable capacity of 108 mAh g(-1) can still be maintained. Besides, this material also shows excellent cycling stability, at a current density of 5 A g(-1), the reversible capacity can still reach 149 mAh g(-1) after 5000 cycles. This work will provide significant value for the development of both carbon materials and SIBs anode materials.

    2014-01-01

    The aim of the present work was to study and develop an innovative, clean, and environmentally friendly process for lactulose synthesis by electroactivation of lactose. In this work, the electrode material (type 304 stainless steel, titanium, and copper), dimensionless interelectrode-membrane distance at the cathodic compartment (0.36, 0.68, and 1), and the membrane:electrode surface area ratio (0.23, 0.06, and 0.015) were considered to be the factors that could affect the kinetic conversion of lactose into lactulose. The reactions were conducted under an initial lactose concentration of 0.15mol/L at 10°C, Froude number (mixing speed) of 2.05×10(-2), and electric current intensity of 300mA for 30min. The highest lactulose formation yield of 32.50% (0.05mol/L) was obtained by using a copper electrode, interelectrode-membrane distance of 0.36, and membrane:electrode surface area ratio of 0.23. The 2-parameter Langmuir, Freundlich, and Temkin isotherm models were used for the prediction of the lactose isomerization kinetics as well as the 3-parameter Langmuir-Freundlich isotherm model. It was shown that the lactose isomerization kinetics into lactulose followed the Temkin and Langmuir-Freundlich models with coefficients of determination of 0.99 and 0.90 and a relative error of 1.42 to 1.56% and 4.27 to 4.37%, respectively.

    Dates about the research of biodegradation of epoxy-polyurethane composite material used in reconstructive and reparative surgery of maxillofacial area are reflected in the article. Was founded: 1) notable biodegradation of species from epoxy-polyurethane composition in the term of observation up to 6 months was not founded. That testifies their preservation of physical and mechanical properties. 2) founded, that in species from epoxy-polyurethane composition, which contain levamisole, processes of biodegradation are faster then in species from pure epoxy-polyurethane composition and in species from epoxy-polyurethane composition with hydroxyapatite; 3) material from epoxy-polyurethane composition, which contains levamisole and hydroxyapatite, stays in biological environment in small quantity of petty fragments during the incubation in term of 2 years. So, it biodegrades practically totally. Authors suggest on the basis of achieved information, that the use of epoxy-polyurethane constructions that biodegrade, is pertinently in reconstructive maxillofacial surgery.

    2017-01-01

    Renewing a veterinary curriculum is challenging work and its impact is difficult to measure. Academic leaders are charged with regular review and updating of their curricula, but have few resources available to guide their efforts. Due to the paucity of published veterinary reports, most turn to colleagues at other veterinary schools for insider advice, while a few undertake the task of adapting information from the educational literature to suit the needs of the veterinary profession. In response to this paucity, we proposed a theme issue on curricular renewal and surveyed academic leaders regarding curricular challenges and major renewal efforts underway. We compiled the results of this survey (with respondents from 38 veterinary colleges) as well as publicly available information to create a digest of curricular activities at AAVMC member institutions. This introductory article summarizes the key survey findings, describes the methods used to create the curricular digest, and presents information about key aspects of selected programs. Our overarching research questions were as follows: (1) What was the extent and nature of curricular change at AAVMC-accredited veterinary colleges over the past 5 years? and (2) How are curricula and curricular changes managed at AAVMC accredited veterinary colleges? The appended curricular digests provide selected details of current DVM curricula at participating institutions. Additional articles in this issue report on institutional change efforts in more detail. It is our hope that this issue will help to pave the way for future curricular development, research, and peer-to-peer collaboration.

    This preliminary study of parental participation in curricular and extra-curricular activities was conducted in the general framework of the healthy heart project in St. Louis du Parc, an underprivileged and multiethnic neighbourhood in Montreal. A general understanding of this type of participation is essential in order to adapt the role parents play in health programs developed in conjunction with the school. A conceptual framework was developed to help understand how and why parents of primary school children participate in school activities. Qualitative analysis of 15 semi-directed interviews conducted with various schools and other organizations revealed those obstacles to parental involvement, and the factors that encourage parents to participate. It was clear that there were wide social and cultural gaps between parents and schools. An important factor is how people perceive those barriers. Teachers stressed organizational and language communications difficulties. Others pointed to the lack of knowledge of the community, to poor communications skills and the parents' lack of those skills that would allow them to participate actively. A more open-minded attitude by school authorities and a more proactive and positive attitude of teachers toward parents are essential requirements, but not the only ones. Further interviews with parents should help provide more details and information.

  17. Educating the educators: a key to curricular integration.

    Science.gov (United States)

    Haramati, Aviad

    2015-02-01

    According to Hopkins and colleagues, integration of basic science and clinical practice in the medical curriculum has been "incremental" at best, rather than transformative, in part because of a lack of focus on the individuals central to the integration--basic science educators. These authors maintain that those who lead change in education should not only address the systemic structure but also understand the meaning of integration for individual basic scientists at different levels of change. Their view has merit, and this Commentary author suggests three concrete steps that institutions should undertake to engage basic scientists who are interested in becoming "educationally literate" and assuming leadership roles in curriculum integration: (1) Offer opportunities to help interested basic science teaching faculty gain the necessary expertise to become skilled educators; (2) establish institutional programs and structures that foster a community of medical educators across departments and schools; and (3) align institutional priorities and incentives to promote, rather than hinder, integration in medical education. In essence, curricular integration cannot succeed if the participants do not understand the "language of education." Furthermore, faculty who opt for an education-focused career path should be brought together from across departments, centers, and schools to create a community of educators within the academic health center. Finally, institutional leaders should place high value and proper incentives in terms of recognition and opportunities for faculty advancement to ensure that those opting to gain additional training as skilled educators will drive innovation and help move curricular reform from incremental change to transformation.

  18. Managing curricular change in the UWI medical schools.

    2001-12-01

    The ideal operational curriculum is dynamic. It is alive, constantly responding to changes within the social milieu served by its programmes. The medical curriculum of the University of the West Indies (UWI) has not been readily responsive to its catchment society's changing needs. This lack of resilience has created both curricular and administrative problems that have remained unsolved. Now, at the threshold of the twenty-first century, many more fundamental curricular changes are imperative in the UWI medical programme if the Faculty of Medical Sciences (FMS) is to be able to withstand the territorial invasions imminent from the global digital institutions of the new age. The new changes that will place the medical curriculum in line with the demands of the new Information Age will also remove the obnoxious effects of the 'dual curriculum' question and related issues. The Change Formula (Ch = V x P x D > C) that has worked the corporate transformations and realignments of the late twentieth century is applied to the thoughts of a reformed management of the UWI medical curriculum, and its ability to break down walls of resistance to change and liberate the curriculum to full dynamism is discussed.

  19. Low cost solution-based materials processing methods for large area OLEDs and OFETs

    Jeong, Jonghwa

    In Part 1, we demonstrate the fabrication of organic light-emitting devices (OLEDs) with precisely patterned pixels by the spin-casting of Alq3 and rubrene thin films with dimensions as small as 10 mum. The solution-based patterning technique produces pixels via the segregation of organic molecules into microfabricated channels or wells. Segregation is controlled by a combination of weak adsorbing characteristics of aliphatic terminated self-assembled monolayers (SAMs) and by centrifugal force, which directs the organic solution into the channel or well. This novel patterning technique may resolve the limitations of pixel resolution in the method of thermal evaporation using shadow masks, and is applicable to the fabrication of large area displays. Furthermore, the patterning technique has the potential to produce pixel sizes down to the limitation of photolithography and micromachining techniques, thereby enabling the fabrication of high-resolution microdisplays. The patterned OLEDs, based upon a confined structure with low refractive index of SiO2, exhibited higher current density than an unpatterned OLED, which results in higher electroluminescence intensity and eventually more efficient device operation at low applied voltages. We discuss the patterning method and device fabrication, and characterize the morphological, optical, and electrical properties of the organic pixels. In part 2, we demonstrate a new growth technique for organic single crystals based on solvent vapor assisted recrystallization. We show that, by controlling the polarity of the solvent vapor and the exposure time in a closed system, we obtain rubrene in orthorhombic to monoclinic crystal structures. This novel technique for growing single crystals can induce phase shifting and alteration of crystal structure and lattice parameters. The organic molecules showed structural change from orthorhombic to monoclinic, which also provided additional optical transition of hypsochromic shift from

    Concrete which is generally used as filling material for a buried cavity has very high strength but significantly high self-load is considered its disadvantage. If it is used as filling material, the second collapse due to additional load, causing irreversible damage. If light-weighted foam and active feldspar are used to solve this problem, the second collapse can be prevented by reducing of self-load of filling material. In this study, the specimen was produced by mixing light-weighted foam, active feldspar and cement, and changes in the density, unconfined compressive strength and hydraulic conductivity were analyzed. Using the light-weighted foam could enable the adjustment of density of specimen between 0.5 g/cm3 and 1.7 g/cm3, and if the mixing ratio of the light-weighted foam increases, the specimen has more pores and smaller range of cross-sectional area. It is confirmed that it has direct correlation with the density, and if the specimen has more pores, the density of the specimen is lowered. The density of the specimen influences the unconfined compressive strength and the hydraulic conductivity, and it was also confirmed that the unconfined compressive strength could be adjusted between 0.6 MPa and 8 MPa and the hydraulic conductivity could be adjusted between 10-9cm/sec and 10-3cm/sec. These results indicated that we can adjust unconfined compressive strength and hydraulic conductivity of filling materials by changing the mixing amount of lightweight-weighted foam according to the requirements of the field condition.

    To overcome the absence of socio-economic information in administrative databases and to monitor social inequalities in health, a material and social deprivation index was developed for Québec and Canada. The index is based on the smallest area unit used in Canadian censuses, with 400 to 700 persons on average. It includes six socio-economic indicators grouped along two dimensions - material and social - produced from principal component analyses. The index exists for 1991, 1996, 2001 and 2006 and in different versions, from local areas to the whole of Canada. Numerous products related to the index are available online free of charge. The index has been used extensively in the field of health and social services, mainly in the province of Québec but also elsewhere in Canada. It has had four main uses, all related to public health: describing geographic variations of deprivation, illustrating inequalities in population health status and in service use according to deprivation, supporting the development of health reports and policies, and guiding regional resource allocation. These applications are facilitated by a close partnership between the producers and users of the index. The deprivation index is a marker of social inequalities in health. It allows for monitoring of inequalities over time and space, and constitutes a useful tool for public health planning, intervention and service delivery.

    The focus of the project was to design and synthesize light element compounds and nanomaterials that will reversibly store molecular hydrogen for hydrogen storage materials. The primary targets investigated during the last year were amine and hydrogen terminated silicon (Si) nanoparticles, Si alloyed with lighter elements (carbon (C) and boron (B)) and boron nanoparticles. The large surface area of nanoparticles should facilitate a favorable weight to volume ratio, while the low molecular weight elements such as B, nitrogen (N), and Si exist in a variety of inexpensive and readily available precursors. Furthermore, small NPs of Si are nontoxic and non-corrosive. Insights gained from these studies will be applied toward the design and synthesis of hydrogen storage materials that meet the DOE 2010 hydrogen storage targets: cost, hydrogen capacity and reversibility. Two primary routes were explored for the production of nanoparticles smaller than 10 nm in diameter. The first was the reduction of the elemental halides to achieve nanomaterials with chloride surface termination that could subsequently be replaced with amine or hydrogen. The second was the reaction of alkali metal Si or Si alloys with ammonium halides to produce hydrogen capped nanomaterials. These materials were characterized via X-ray powder diffraction, TEM, FTIR, TG/DSC, and NMR spectroscopy.

    Mesoporous materials with the highest surface area were synthesized by hydrothermal treatment from coal-measure kaolin using cetyltrimethylammonium bromide (CTAB) as template. The effect of several factors on surface area of products also had been discussed. The products were characterized by FTIR, HRTEM and N2 adsorption and desorption isotherm plot methods. There was typical structure as Si-O, Si-OH and Si-O-Si of mesoporous materials in the framework of synthesized materials; the pore size distributions of the products showed a sharp peak at 3.82 nm. The effect of hydrothermal treatment time and the amount of template on the specific surface area of mesoporous materials was important, when the Surf/Si = 0.135, and hydrothermal time = 12 h, and the surface area of the product reached up to 1 070 m2/g, which was higher than other products.

    Carbon nanotubes (CNTs) are a promising replacement for tungsten filaments as electron emitters in conventional x-ray sources, owing to their higher aspect ratio, superior mechanical stability, chemical inertness, and high electrical and thermal conductivities. Conditions for realizing the best emission behavior from CNTs have been formulated over the last few years. In this paper, we report the relatively less-investigated factor, namely, the influence of the nature of substrate material on the growth as well as field emission characteristics of large-area multiwalled CNTs for their practical application in medical x-ray sources. We compare the morphology of CNTs on a variety of substrates such as stainless steel, copper, molybdenum, graphite, few-layer graphene, and carbon nanowalls grown by thermal chemical vapor deposition following a simple drop-coating of catalyst. We find that CNTs grown on stainless steel and graphite show the best combination of emission characteristics under pulsed operation mode. These studies are helpful in selecting the optimum substrate material for field emission applications. Ex situ studies on field emission degradation of CNTs are presented towards the end.

    Full Text Available The lateritic soils that overburden Charnockite and Gneiss Complexes in Ipele-Owo area of Ondo State, Nigeria are in great use for local construction. However, little is known of their engineering properties and suitability as sub-grade and sub-base materials for large-scale building and road construction. This work utilized standard geotechnical analytical techniques to examine and characterize these laterites. The results show that the soil is characteristically of a moderate strength based on the average California Bearing Ratio (CBR test result of 52.5%. The average particle size distribution indicates 11% fine grained sand, 2% medium grains, 12.4% coarse grains, 2% fine gravel and 74.6% clay-sized particles. The respective values of the linear shrinkage, liquid and plastic limits are 10.5%, 52.7% and 23.45%. The maximum dry density of the laterites is 1778.5 kg/m3 while the moisture content is 17.65%. It is therefore suggested that the Ipele-Owo laterites are suitable for use as sub-grade and sub-base construction materials since the geotechnical properties are fairly within the regulatory standards in Nigeria

    McElroy, Mack; de Carvalho, Nelson; Estes, Ashley; Lin, Shih-yung

    2017-01-01

    Use of lightweight composite materials in space and aircraft structure designs is often challenging due to high costs associated with structural certification. Of primary concern in the use of composite structures is durability and damage tolerance. This concern is due to the inherent susceptibility of composite materials to both fabrication and service induced flaws. Due to a lack of general industry accepted analysis tools applicable to composites damage simulation, a certification procedure relies almost entirely on testing. It is this reliance on testing, especially compared to structures comprised of legacy metallic materials where damage simulation tools are available, that can drive costs for using composite materials in aerospace structures. The observation that use of composites can be expensive due to testing requirements is not new and as such, research on analysis tools for simulating damage in composite structures has been occurring for several decades. A convenient approach many researchers/model-developers in this area have taken is to select a specific problem relevant to aerospace structural certification and develop a model that is accurate within that scope. Some examples are open hole tension tests, compression after impact tests, low-velocity impact, damage tolerance of an embedded flaw, and fatigue crack growth to name a few. Based on the premise that running analyses is cheaper than running tests, one motivation that many researchers in this area have is that if generally applicable and reliable damage simulation tools were available the dependence on certification testing could be lessened thereby reducing overall design cost. It is generally accepted that simulation tools if applied in this manner would still need to be thoroughly validated and that composite testing will never be completely replaced by analysis. Research and development is currently occurring at NASA to create numerical damage simulation tools applicable to damage in

    Full Text Available Abstract Background Few studies have investigated how area-level deprivation influences the relationship between individual disadvantage and suicide mortality. The aim of this study was to examine individual measures of material and social disadvantage in relation to suicide mortality in Canada and to determine whether these relationships were modified by area deprivation. Methods Using the 1991-2001 Canadian Census Mortality Follow-up Study cohort (N = 2,685,400, measures of individual social (civil status, family structure, living alone and material (education, income, employment disadvantage were entered into Cox proportional hazard models to calculate hazard ratios (HR and 95% confidence intervals (CI for male and female suicide mortality. Two indices of area deprivation were computed - one capturing social, and the other material, dimensions - and models were run separately for high versus low deprivation. Results After accounting for individual and area characteristics, individual social and material disadvantage were associated with higher suicide mortality, especially for individuals not employed, not married, with low education and low income. Associations between social and material area deprivation and suicide mortality largely disappeared upon adjustment for individual-level disadvantage. In stratified analyses, suicide risk was greater for low income females in socially deprived areas and males living alone in materially deprived areas, and there was no evidence of other modifying effects of area deprivation. Conclusions Individual disadvantage was associated with suicide mortality, particularly for males. With some exceptions, there was little evidence that area deprivation modified the influence of individual disadvantage on suicide risk. Prevention strategies should primarily focus on individuals who are unemployed or out of the labour force, and have low education or income. Individuals with low income or who are living alone in

    Full Text Available This paper presents an educational practice based on the implementation of a resource designed and produced ad hoc, by fostering passion for literature in the last year of primary education. Thus, we are able to reach many contents settled in the curricula of Spanish Language, Social Sciences, Natural Sciences and Social and Civic Values, established in the Spanish Education Act 8/2013, of December 9, for improvement of educational quality (commonly known as LOMCE. The evidence we have tested suggests that students feel a special motivation not only to the rich literary elements at our disposal, but also enrich their knowledge and social values in other academic and personal settings. At this point, we believe that this way of working the curriculum in a more interactive way is a great motivator for the assimilation of content from different areas and skills development element, as it is also capable of being applied to a greater or lesser extent curricular areas and other educational realities.

Para tal propósito, se analizaron los fundamentos curriculares económicos, socioculturales, filosóficos y pedagógicos del currículum costarricense, durante el Estado Neoliberal, en relación con la construcción de una ciudadanía neoliberal; obteniendo una caracterización general de la influencia, directa e indirecta, de un proyecto hegemónico cultural-económico y la formación ciudadana y sus implicaciones educativas.Abstract:The current essay, developed as a complement to the formative activities of the Masters in Curricular Planning of the University of Costa Rica, tries to vindicate the role of the Costa Rican educative system -focused on the curricular area- within the formation of a citizen as an answer to neoliberal political and economical interests, making him a subjective and not neutral social and historical product. In order to reach this goal, the economical, sociocultural, philosophical and pedagogical curricular principles of the Costa Rican curriculum design -during the neoliberal state- were analyzed, in relation to the formation of a neoliberal citizenship. This analysis was made, and a general characterization -of direct and indirect influence- of a cultural and economical hegemonic project was obtained, as well as the citizenship formation and its educative implications.

    Full Text Available Introduction. The importance of socio-economic factors in differentiating the physical activities of children and teenagers keeps changing. That is why the goal of this research was to identify certain social variables amongst those listed most often which differentiate the level of targeted physical activity of urban children and youths from the Bialskie district. Material and methods. The research was conducted on 1.084 students between the ages of 10 and 18. Three age groups were chosen: 10 to 12, 13 to 15, and 16 to 18. Information about the attendance of respondents in Physical Education classes and structured extra-curricular sport activities, as well as preferred forms of physical activities were collected via a diagnostic survey. The same method was used in the assessment of the socio-economic status of the families of the respondents. The relations between attendance in extra-curricular sports activities and socio-economic factors was assessed by a multifactoral logistic regression model, and the statistical relevance of the differences was calculated by the Wald test. Results. Attendance in structured extra-curricular physical activity depended mostly on income per family member. In the case of type of work performed by parents, the attendance rate in both boys and girls was higher if the parents performed intellectual work. Parents' education and number of children in the family did not have a high influence on the attendance of respondents in structured extra-curricular sport activities. Conclusions. Increasing disproportions in societal prosperity can be an important factor limiting the attendance of the poorest group of children and youths in structured physical activities. The lack of influence on physical activity of such socio-economic variables as parents' education and the number of children in the family can be connected with the change of meaning of those factors in modern society (depreciation of the importance of higher

    NASA Langley Research Center has successfully developed an electron beam freeform fabrication (EBF3) process, a rapid metal deposition process that works efficiently with a variety of weldable alloys. The EBF3 process can be used to build a complex, unitized part in a layer-additive fashion, although the more immediate payoff is for use as a manufacturing process for adding details to components fabricated from simplified castings and forgings or plate products. The EBF3 process produces structural metallic parts with strengths comparable to that of wrought product forms and has been demonstrated on aluminum, titanium, and nickel-based alloys to date. The EBF3 process introduces metal wire feedstock into a molten pool that is created and sustained using a focused electron beam in a vacuum environment. Operation in a vacuum ensures a clean process environment and eliminates the need for a consumable shield gas. Advanced metal manufacturing methods such as EBF3 are being explored for fabrication and repair of aerospace structures, offering potential for improvements in cost, weight, and performance to enhance mission success for aircraft, launch vehicles, and spacecraft. Near-term applications of the EBF3 process are most likely to be implemented for cost reduction and lead time reduction through addition of details onto simplified preforms (casting or forging). This is particularly attractive for components with protruding details that would require a significantly large volume of material to be machined away from an oversized forging, offering significant reductions to the buy-to-fly ratio. Future far-term applications promise improved structural efficiency through reduced weight and improved performance by exploiting the layer-additive nature of the EBF3 process to fabricate tailored unitized structures with functionally graded microstructures and compositions.

    In order to increase scientific literacy and the knowledge of science and technology of Europe's citizens, the European Commission suggests a more student-centred implementation of natural sciences in education systems. Inquiry-based learning (IBL) is not only an accepted method to promote students' interest and motivation, it also helps students learn the scientific method and fosters their research skills. However, IBL is rarely used in European classrooms. The main reason is that due to the strict curricula teachers do not have the time for preparation and they do not feel well equipped and trained in the use of IBL methods in class. The Photonics Explorer programme addresses these problems on the European level. Within the programme, a pan-European collaboration of professors, teachers and photonics experts have developed the Photonics Explorer kit for the teaching of optics and light-related topics in physics across various European secondary school curricula. It is designed for intra-curricular use and contains specially designed, hands-on experimental components, worksheets based on guided IBL and multimedia material. Additionally, the kit provides a teacher guide with a suggested lesson outline and sufficient background information for each topic.

  11. Influence of dielectric materials on uniformity of large-area capacitively coupled plasmas for N2/Ar discharges

    2016-10-01

    The effect of the dielectric ring on the plasma radial uniformity is numerically investigated in the practical 450-mm capacitively coupled plasma reactor by a two-dimensional self-consistent fluid model. The simulations were performed for N2/Ar discharges at the pressure of 300 Pa, and the frequency of 13.56 MHz. In the practical plasma treatment process, the wafer is always surrounded by a dielectric ring, which is less studied. In this paper, the plasma characteristics are systematically investigated by changing the properties of the dielectric ring, i.e., the relative permittivity, the thickness and the length. The results indicate that the plasma parameters strongly depend on the properties of the dielectric ring. As the ratio of the thickness to the relative permittivity of the dielectric ring increases, the electric field at the wafer edge becomes weaker due to the stronger surface charging effect. This gives rise to the lower ion density, flux and N atom density at the wafer edge. Thus the homogeneous plasma density is obtained by selecting optimal dielectric ring relative permittivity and thickness. In addition, we also find that the length of the dielectric ring should be as short as possible to avoid the discontinuity of the dielectric materials, and thus obtain the large area uniform plasma.

    Full Text Available The present study was realized in a Greek 6th grade State Primary School class and was based on Howard Gardner’s theory of multiple intelligences, which was first introduced in 1983. More particularly, it was explored to what extent the young learners possess multiple intelligences through the use of a specially-designed questionnaire and a series of interviews. The findings of the above have served as a tool to the construction of a project work based on students’ learning preferences within a cross-curricular framework, easily applicable to the Greek State School curriculum. All learners were activated to participate within a school environment that traditionally promotes linguistic and mathematical skills matching dominant multiple intelligences or a combination of some of them to thematic units already taught by Greek teachers. The suggested project was assessed through observation and student portfolio, showing that the young learners’ multiple intelligences were exploited to a great extent, promoting the learning process satisfactorily. The results of this study can provide a contribution to the literature of multiple intelligences in the Greek reality and suggest a need for further consideration and exploration in the field. Finally, the researcher of this study hopes the present work could function as a springboard for more elaborated studies in the future.

    2016-03-01

    Full Text Available Instructed second language acquisition (ISLA has been referenced in the larger field of the SLA literature for over two and a half decades. Currently, there are several theoretical underpinnings accounting for processes assumed to play a role in ISLA and quite an impressive number of studies have empirically addressed some aspect(s of ISLA. Recently, a lengthy and relatively cohesive treatise of this substrand of SLA research in relation to both theoretical, empirical, and pedagogical perspectives has been published in two books (cf. Leow, 2015a; Loewen, 2015, and a new model of the L2 learning process in ISLA has been proposed (Leow, 2015a. These publications are timely and important given that the concept of ISLA not only needs to be clearly defined but also situated contextually. To this end, this article (a revisits current definitions of ISLA in the SLA literature with the aim of identifying specific features of ISLA that underlie such definitions, (b deconstructs ISLA by probing deeper into what comprises the terms instructed and SLA in ISLA, (c provides a brief summary of the cognitive processes and variables postulated by the theoretical underpinnings of ISLA and pertinent empirical research, (d recommends that ISLA be observed from one curricular approach together with its empirical and pedagogical ramifications, and (e provides some measure of direction future ISLA research may follow.

    2013-09-01

    Full Text Available This qualitative study looked at the instructional, curricular and organizational factors impacting on the adoption of mobile learning in a higher education institution. Academics expressed their views on a variety of educational issues likely to enhance or hinder the effectiveness of the innovation. Teachers requested more professional development in a number of key areas including the integration of the technology into teaching and learning. Likewise, resolving vital issues such as workload, equity to access and effective policy making were seen as key to successful adoption. Technical issues such as having good wireless connectivity, need for efficient technical support, access to mobile devices and an understanding of their operational limitations with respect to desk/laptops were also highlighted. The study revealed a number of alternative perceptions and misconceptions, about articulating effective mobile learning pedagogies. For instance, staff expressed concerns about the risk of exposing students to superficial learning when mobile learning experiences were not well designed, the prospect that the devices might distract students from learning, as well as a possible deterioration of the quality of interaction between academics and students. Recommendations to reconcile those alternative conceptions with best practice principles are outlined.

    A geological study carried out in the Bomkoul area (Douala sub-basin, Cameroon) has revealed the presence of heterogeneous clayey materials on hills (80-120 m altitude). The clay deposits are thick at the upper slope where sandstones and sandy-clay overlying clay layers, and thin at the middle and lower slopes where weathered clays overlying clay layers. Clayey materials identified are grey, dark-grey and mottled in color, with sandy-clay, clayey-silt, silty-clay and clay textures. Raw materials are mostly made up of fine particles ranging from 52 to 82% clay and silt in the mottled clayey material, 50 to 82% clay and silt in the dark-grey clayey material and 70 to 85% in the grey clayey material. Their chemical composition is characterized by silica (clay minerals are disorganized and poorly crystallized kaolinite and few smectite. The physical, mineralogical and geochemical properties of these materials presented and discussed in this work show that the clayey raw materials of the Bomkoul area have a good potential for pottery as well as brick, tile and soil sandstone manufacture.

    Full Text Available In the article, an analysis is made of curricular renovation in the medical program at Universidad de Antioquia, in Medellín, Colombia, especially between 2000 and 2005; its purpose focused on moving from a traditional and technological concept of the curriculum to an integrationist tendency, centered on the student, flexible, focused on the cognitive processes and on achieving the training of a physician capable of answering to social, local and global needs. The implementation of Problem Based Learning is analyzed as well as other didactic strategies, the role of the tutor and internal debate on competences. The study plan was organized around problematic areas, while the previous plan was structured starting from disciplines. The program included new areas of knowledge, among them medical information technology, analysis of human sexuality, communication and phases of the vital cycle not previously contemplated, such as adolescence and old age. Disciplines oriented to health and society were posed in a longitudinal manner and health promotion, disease prevention and attention, and rehabilitation were considered as transcurricular axes. However, a fragmentary mentality that separates disciplines continues to predominate, there is a need to increase practice areas outside the hospital environment, evaluation remains as one of the critical aspects and administrative adjustment is pending. Curricular management should be permanent with ample participation of both faculty and students. En este artículo se hace un análisis de la renovación curricular en el programa de medicina de la Universidad de Antioquia, especialmente entre los años 2000 y 2005, cuyo propósito se enfocaba en pasar de una concepción tRadicional y tecnológica del currículo a una tendencia integracionista, centrada en el estudiante, flexible, enfocada en los procesos cognitivos y en lograr la formación de un médico capaz de darles respuesta a las necesidades sociales

  6. Questioning collectives and agencies: a commentary on curricular choices

    This commentary explores theoretical alternatives for viewing the problem identified by Volny Fages and Virginie Albe in their article entitled Social issues in nanoscience and nanotechnology Master's degrees: The socio-political stakes of curricular choices. An approach to social research is suggested that would render visible the associations maintaining the states of affairs depicted by Fages and Albe. In their research, Fages and Albe identified conceptions of the relationship between scientific endeavour and social concerns to be at the root of "choices" made by coordinators of Masters programs in nano science and technology in universities selected for their study. Albe and Fages, insiders in the sense that they take responsibility for a particular program within one such course, convey their belief that, "future scientists need to identify, accept and take on board the social responsibilities linked to their own practice of science, and to work collectively for a more democratic division of power regarding socio-technical choices". However, many of the Master's programs reviewed in their research were reported as providing limited opportunities for their students to critically engage with social aspects of scientific work. This commentary questions the notion of "choices" used in their research and proposes Actor-Network Theory as a theoretical framework open to the existence of various human and non-human agencies at work when a "choice" is made. The aim of the commentary is to further Fages and Albe's agenda by calling for understanding and ultimately a reassembling of the state of affairs in a way that would be acceptable to those invested.

  7. Competency-based curricular design to encourage significant learning.

    Hurtubise, Larry; Roman, Brenda

    Most significant learning (SL) experiences produce long-lasting learning experiences that meaningfully change the learner's thinking, feeling, and/or behavior. Most significant teaching experiences involve strong connections with the learner and recognition that the learner felt changed by the teaching effort. L. Dee Fink in Creating Significant Learning Experiences: An Integrated Approach to Designing College Course defines six kinds of learning goals: Foundational Knowledge, Application, Integration, Human Dimension, Caring, and Learning to Learn. SL occurs when learning experiences promote interaction between the different kinds of goals, for example, acquiring knowledge alone is not enough, but when paired with a learning experience, such as an effective patient experience as in Caring, then significant (and lasting) learning occurs. To promote SL, backward design principles that start with clearly defined learning goals and the context of the situation of the learner are particularly effective. Emphasis on defining assessment methods prior to developing teaching/learning activities is the key: this ensures that assessment (where the learner should be at the end of the educational activity/process) drives instruction and that assessment and learning/instruction are tightly linked so that assessment measures a defined outcome (competency) of the learner. Employing backward design and the AAMC's MedBiquitous standard vocabulary for medical education can help to ensure that curricular design and redesign efforts effectively enhance educational program quality and efficacy, leading to improved patient care. Such methods can promote successful careers in health care for learners through development of self-directed learning skills and active learning, in ways that help learners become fully committed to lifelong learning and continuous professional development.

    Different land cover types in Otindag Sandy Land and Bashang area of Hebei Province are linked to a material source of sand stormy weather in Beijing based on results of field vegetation and soil survey and laboratory works. Results of grain size analysis show that dust release potential in per unit area of moving sandy land is small, while lowland meadow and meadow steppe in stony hillshave high potential of releasing dusts in per unit area during sand stormy weather occurrence. Further considering the effects of vegetation, it is inferred that the moving sandy land served as a material source of past dust storm and the possibility of dust release in per unit area is low in current time. Typical steppe in stony hills is undergoing desertification and its dust release possibility in per unit area is high. Farmland has strong potential of release dusts when they are ploughed in spring, but a large amount of therophytes grow and thus prevent dusts from release when cultivation was terminated. Potentials of dust release in per unit area in fixed sand dunes, stony mountain meadow steppe and lowland meadow are low due to high cover of perennials. Sand dune reactivation and desiccation of lakes and lowlands under estimated future climatic change will makethem serve as a future material source of sand stormy weather.

    The goal of disposing of low-level radioactive and hazardous waste in shallow landfills is to reduce risk to human health and the environment by isolating contaminants until they no longer pose an unacceptable hazard. In order to achieve this, the Department of Energy Environmental Restoration Program is comparing the performance of several different surface covers at Material Disposal Area (MDA) B in Los Alamos. Two conventional landfill were compared with an improved cover designed to minimize plant and animal intrusion and to minimize water infiltration into the underlying wastes. The conventional covers varied in depth and both conventional and improved designs had different combinations of vegetation (grass verses shrub) and gravel mulch (no mulch verses mulch). These treatments were applied to each of 12 plots and water balance parameters were measured from March1987 through June 1995. Adding a gravel mulch significantly influenced the plant covered field plots receiving no gravel mulch averaged 21.2% shrub cover, while plots with gravel had a 20% larger percent cover of shrubs. However, the influence of gravel mulch on the grass cover was even larger than the influence on shrub cover, average grass cover on the plots with no gravel was 16.3%, compared with a 42% increase in grass cover due to gravel mulch. These cover relationships are important to reduce runoff on the landfill cover, as shown by a regression model that predicts that as ground cover is increased from 30 to 90%,annual runoff is reduced from 8.8 to 0.98 cm-a nine-fold increase. We also found that decreasing the slope of the landfill cover from 6 to 2% reduced runoff from the landfill cover by 2.7-fold. To minimize the risk of hazardous waste from landfills to humans, runoff and seepage need to be minimized and evapotranspiration maximized on the landfill cover. This has to be accomplished for dry and wet years at MDA B. Seepage consisted of 1.9% and 6.2% of the precipitation in the average and

    From 1982 through 1987, Los Alamos National Laboratory (LANL) performed surety laboratory operations for the U.S. Army Medical Research and Development Command (MRDC). Room 4009 in building SM-29, TA-3, was used as the laboratory for work with the following chemical surety material (CSM) agents: sarin (GB), soman (GD), lewisite (L), and distilled mustard (HD) radio-labelled with H{sup 3} or C{sup 14}. The work was confined to three CSM-certified fume hoods, located in room 4009 (see diagram in Appendix C). The laboratory ceased all active operations during the late 1986 and early 1987 period. From 1987 until 1993 the laboratory was secured and the ventilation system continued to operate. During late 1992, the decision was made to utilize this laboratory space for other operations, thus a decision was made to dismantle and reconfigure this room. LANL sub-contracted Battelle Memorial Institute (BMI) to draw upon the CSM experience of the technical staff from the Hazardous Materials Research Facility (HMRF) to assist in developing a decontamination and decommissioning plan. BMI was subcontracted to devise a CSM safety training course, and a sampling and air monitoring plan for CSM material to ensure personnel safety during all disassembly operations. LANL subcontracted Johnson Controls personnel to perform all disassembly operations. Beginning in early 1993 BMI personnel from the HMRF visited the laboratory to develop both the safety plan and the sample and air monitoring plan. Execution of that plan began in September 1993 and was completed in January 1994.

    Full Text Available The physicochemical, mineralogical and technological properties of clayey materials from the Ndop plain (NW Cameroon have been investigated, for their ceramic applications. The clayey materials have mixed facies with colour ranging from brown, grey, mottled and yellowish brown. The thickness of the exploitable clay layer is more than 5 m. Their mineralogical constituents are quartz, kaolinite, illite and feldspars, with kaolinite as major clay mineral. Based on the geochemistry, their source rocks might be felsic, with a mafic rock inference. These materials display high percentage in fine particles and high Atterberg limits. For all the firing temperatures, flexural strength (1.2–11 MPa, water absorption (8.03–24.27%, linear shrinkage (2.10%, weight loss (4.88–16.54% and bulk density (1.57–2.03 g/cm3 indicate good ceramic properties for firing samples between 900 and 1100 °C. Most of the fired test bricks show a brick red colour with good to very good cohesion. The studied clays were thus, suitable as raw materials for roof tiles, light weight blocks and hollow bricks; however, mixing of high clayey and highly silty materials could improve the quality of the products.

    Schmeck, J; Schmeck, S B; Kohnen, W; Werner, C; Schäfer, M; Gervais, H

    2008-08-01

    The implementation of diagnosis-related groups (DRGs) sharply increased economic pressure on hospitals. Hence, process optimization was focussed on cost-intensive areas, namely the operation room (OR) departments. Work-flow in the OR is characterized by a mandatory interlocking of the job functions of many different occupational groups and the availability of a variety of different materials. Alternatives for staff assignment optimization have been published in numerous publications dealing with the importance of OR management. In this connection the issue of material logistics in the context of OR management has not been frequently addressed. In order to perform a surgical procedure according to plan, one depends on personnel and on timely availability of the materials needed. Supply of sterilized materials is of utmost importance, because in most hospitals sterilized surgical devices constitute a critical resource. In order to coordinate the OR process with the production flow of sterilized materials, an organizational connection to the OR management makes sense. Hence, in a German university hospital the Department of Hospital Sterile Supplies was integrated into the OR management of the Department of Anesthesiology. This led to a close coordination of work-flow processes, and concomitantly a significant reduction of production costs of sterile supplies could be achieved by direct interaction with the OR. Thus, hospital sterile supplies can reasonably be integrated into an OR management representing a new interesting business area for OR organization.

    Full Text Available This article presents the administration of the curricular reorientation that occurred in the municipal district of Dourados-MS in the period 2001 to 2008, trying to describe the official proposal of the process of curricular reorientation and to identify the barriers and facilitators in the materialization of the management. The investigation was developed in a qualitative perspective through observation, bibliographical research, a documental corpus and interview with directors, coordinators and teachers of four schools that lived the process. The results evidenced that there was not an effective participation in the moments of conception nor in the definition of the implementation strategies and/ or evaluation of the proposal. In respect to the development and/or reinforcement of the autonomy through the administration, this was compromised, because there was not wide consultation on the implanted methodological alternative. The power relationships inside and outside school stayed unaffected. The results confirm the complexity in the materialization of the democratic administration in the context of the municipal public administration.

  18. Topic Order in Introductory Physics and its Impact on the STEM Curricular Ladder

    Directory of Open Access Journals (Sweden)

    Teresa L Larkin

    2017-02-01

    Full Text Available Introductory physics courses are an important rung on the curricular ladder in STEM. These courses help to strengthen students critical thinking and problem solving skills while simultaneously introducing them to many topics they will explore in more detail in later courses in physics and engineering. For these reasons, introductory physics is a required element on the curricular ladder. Most often, introductory physics is offered as a two-semester sequence with basic mechanics being taught in the first semester and electricity and magnetism in the second. In fact, this curricular sequence has not been altered in decades. Is there a reason for this? There are many other enduring questions that arise pertaining to these foundation courses in physics. These questions include: Does taking the introductory course sequence “out of order” have an impact on student learning in physics? What topics should be taught? When should these topics be taught? What topics could be left out? The list of questions is essentially endless. This paper will address some of these questions in part, through a brief discussion on student learning in a second-semester algebra-based physics course. Connections will also be made to the broader curricular ladder in STEM. To this end, an illustration that makes connections to an engineering statics course will be presented. This discussion will conclude by presenting some broader implications for the larger STEM communities.

  11. A TEMÁTICA AMBIENTAL EM DOCUMENTOS CURRICULARES NACIONAIS DO ENSINO MÉDIO

    Directory of Open Access Journals (Sweden)

    Diógenes Valdanha

    Full Text Available Este artigo relata uma pesquisa que investigou em que medida e extensão a temática ambiental é desenvolvida em documentos curriculares nacionais do Ensino Médio, em continuidade a um estudo anterior que realizou similar investigação, porém em documentos curriculares nacionais do Ensino Fundamental (anos finais. Realizou-se uma análise do conteúdo dos documentos curriculares em uma abordagem qualitativa da pesquisa educacional. Nesses documentos, a presença da temática ambiental é muito menor e menos significativa quando comparada aos do Ensino Fundamental; além de prevalecer uma concepção conservacionista/científica, trazendo uma visão reducionista e pouco politizada/crítica da temática ambiental no processo educativo. Distintamente, as novas Diretrizes Curriculares Nacionais para o Ensino Médio avançam na inclusão de uma educação ambiental crítica no currículo nacional da escola básica.

    A concept that could provide a thin monocrystalline-silicon absorber layer without resorting to the expensive step of epitaxy would be very appealing for reducing the cost of solar cells. The empty-space-in-silicon technique by which thin films of silicon can be formed by reorganization of regular arrays of cylindrical voids at high temperature may be such a concept if the high quality of the thin film could be ensured on centimeter-large areas. While previous works mainly investigated the influence of the porous array on the final structure, this work focuses on the practical aspects of the high-temperature step and its application to large areas. An insight into the defects that may form is given and the origin of these defects is discussed, providing recommendations on how to avoid them. Surface roughening, pitting, formation of holes, and silicon pillars could be attributed to the nonuniform reactions between Si, SiO2, and SiO. Hydrogen atmospheres are therefore preferred for reorganization of macroporous arrays. Argon atmospheres, however, may provide high-quality silicon thin films as well, possibly even more easily transferable, as long as annealing is performed in controlled, clean, and oxygen-free conditions. Our experiments on large areas also highlight the importance of kinetics, which had not been considered up to now and which will require further understanding to ensure a complete reorganization over any wafer area.

    To determine whether changes in the format of teaching pathology and the introduction of active learning principles can improve medical students' performance on external examinations and enhance clinical skills. The sophomore Pathology Course at Jefferson Medical College (JMC) in Philadelphia, Pennsylvania, USA, was completely restructured in 1986, with greater emphasis placed on independent study, small group teaching, and case study discussion. We used the scores of JMC medical students on the National Board of Medical Examiners (NBME) Part I Examination to compare the performance of JMC students who completed their medical education before curricular change (entering classes 1982-1984) with the performance of subsequent generations of students who were taught according to the reformed curriculum (entering classes 1985-1988). The two groups of students were comparable in terms of standard social and psychometric parameters, such as mean age at matriculation, female/male ratio, ratio of minority students in the class, premedical college grade point averages, and mean scores on the preadmission Medical College Admissions Test. JMC students who studied pathology prior to the curricular reform received on the pathology subsection of the NBME Part I Examination reform scores that were close to the national average. In contrast, mean scores for students who studied pathology after curricular changes were significantly higher than the national average (P<0.001). Based on their pathology subscores, the number of JMC students scoring below the cutoff line for passing (380 points) decreased significantly after the curricular reform, whereas the number of high-scoring students whose scores ranked them in the 90th percentile nationally increased. Curricular reform was also associated with an increase in overall student satisfaction. Curricular changes that include an emphasis on active learning can improve the performance of medical students on externally administered

    Additive-type printing techniques such as gravure-offset printing and screen printing are effective for low-cost and ecofriendly electrode pattern formation. Gravure-offset printing is effective for fine pattern formation with widths on the order of 10-20 µm, whereas screen printing is effective for the formation of large-area patterns. However, it is difficult to simultaneously form fine and large-area patterns using these printing techniques. In this study, we demonstrate that fine (minimum width of 15 µm) and medium- as well as large-area patterns can be formed simultaneously using our developed screen-offset printing technique, which is a combination of screen printing on a silicone blanket and transfer printing from the blanket to a substrate. Furthermore, we demonstrate the application of our method to printing on adhesive materials, which allows electrode formation without applying heat to the film substrate.

    It has been about 5 years since the Fukushima nuclear power plant accident, which contaminated large area with radioactive materials. It is necessary to assess radiation dose to establish evacuation areas and to set decontamination goal for the large contaminated area. In this study, we assessed temporal trend of radiation dose to the public living in the large area contaminated with radioactive materials after the Fukushima nuclear power plant accident. The dose assessment was performed based on Chernobyl model and RESRAD model for two evacuation lift areas, Kawauchi and Naraha. It was reported that deposition densities in the areas were 4.3-96 kBq m{sup -2} for {sup 134}Cs, 1.4-300 kBq m{sup -2} for {sup 137}Cs, respectively. Radiation dose to the residents depended on radioactive cesium concentrations in the soil, ranging 0.11-2.4 mSv y{sup -1} at Kawauchi area and 0.69-1.1 mSv y{sup -1} at Naraha area in July 2014. The difference was less than 5% in radiation doses estimated by two different models. Radiation dose decreased with calendar time and the decreasing slope varied depending on dose assessment models. Based on the Chernobyl dosimetry model, radiation doses decreased with calendar time to about 65% level of the radiation dose in 2014 after 1 year, 11% level after 10 years, and 5.6% level after 30 years. RESRAD dosimetry model more slowly decreased radiation dose with time to about 85% level after 1 year, 40% level after 10 years, and 15% level after 30 years. The decrease of radiation dose can be mainly attributed into radioactive decays and environmental transport of the radioactive cesium. Only environmental transports of radioactive cesium without consideration of radioactive decays decreased radiation dose additionally 43% after 1 year, 72% after 3 years, 80% after 10 years, and 83% after 30 years. Radiation doses estimated with cesium concentration in the soil based on Chernobyl dosimetry model were compared with directly measured radiation doses

  8. Variation in chlorophyll content per unit leaf area in spring wheat and implications for selection in segregating material.

    Directory of Open Access Journals (Sweden)

    John Hamblin

    Full Text Available Reduced levels of leaf chlorophyll content per unit leaf area in crops may be of advantage in the search for higher yields. Possible reasons include better light distribution in the crop canopy and less photochemical damage to leaves absorbing more light energy than required for maximum photosynthesis. Reduced chlorophyll may also reduce the heat load at the top of canopy, reducing water requirements to cool leaves. Chloroplasts are nutrient rich and reducing their number may increase available nutrients for growth and development. To determine whether this hypothesis has any validity in spring wheat requires an understanding of genotypic differences in leaf chlorophyll content per unit area in diverse germplasm. This was measured with a SPAD 502 as SPAD units. The study was conducted in series of environments involving up to 28 genotypes, mainly spring wheat. In general, substantial and repeatable genotypic variation was observed. Consistent SPAD readings were recorded for different sampling positions on leaves, between different leaves on single plant, between different plants of the same genotype, and between different genotypes grown in the same or different environments. Plant nutrition affected SPAD units in nutrient poor environments. Wheat genotypes DBW 10 and Transfer were identified as having consistent and contrasting high and low average SPAD readings of 52 and 32 units, respectively, and a methodology to allow selection in segregating populations has been developed.

    Full Text Available The snake-like robot is used for clean-up project in Fukushima nuclear disaster site. The contaminated water at the Fukushima Daiichi nuclear power plants has been purified by the water treatment system, called Advanced Liquid Processing System, co-developed by Japanese and international technologies. The system is used to remove most remaining radioactive contaminants in water that had to be stored at the facility. In this paper, a snake-like robot, incorporated with Advanced Liquid Processing System is introduced for the severe accident in the nuclear power plants in which human cannot control the cleaning-up in the sea where the radioactive materials have been submerged and some resolved in the sea water. The effective strategy of the cleaning-up is analyzed from the environmental protection aspect with the snake's biomechanics and radioactive hazards.

    Full Text Available Introducción: Históricamente los doctorados en ciencias específicas de la salud han sido de tipo investigativo, donde una tesis doctoral que aporte novedad científica y algunos exámenes de mínimo candidato son los ejercicios suficientes para el otorgamiento de los mismos. Este método genera una formación científica lenta y mayormente autodidáctica y no es del todo óptimo cuando se pretende formar doctores en ciencias en un periodo corto de tiempo, o sea en unos cinco años promedio. Por ello la tendencia internacional es la de implementar doctorados curriculares, lo cual garantiza un proceso de formación científica más reflexiva, homogénea, individualizada y tutorial. Objetivos: evaluar el grado de necesidad de la implementación de un doctorado curricular colaborativo en la carrera de Estomatología. Métodos: se realizó un análisis estadístico de la producción de doctorados en ciencias estomatológicas y se describió los resultados de la fundación de la Comisión de Grados de Estomatología. Resultados: en los últimos 35 años se han formado 53 estomatólogos como doctores en ciencias médicas o estomatológicas. El por ciento de estomatólogos con grados científicos fuera de la Capital es muy escaso. Se consideró el ritmo de producción de doctores en ciencias de la Comisión Nacional de Grados de Estomatología como bajo. Conclusiones: los resultados obtenidos demostraron la necesidad y factibilidad de la elaboración e implementación de un doctorado curricular colaborativo para Estomatología.Introduction: Historically, the sciences doctorates health specific has been of investigative type, where a doctoral thesis providing a scientific novelty and some minimal examinations are the exercises enough to grant such doctorate.

    Longsworth, S.A.

    1994-01-01

    Uranium mines in the Monument Valley area were established predominately in channel-fill deposits within the Shinarump Member of the Chinle Formation. The Shinarump Member yields ground water to wells and may yield water to the Moonlight and Radium Hill mines. In the study area near Cameron, uranium was mined from channel-fill deposits within the Petrified Forest Member of the Chinle Formation. Units of the Petrified Forest Member do not yield ground water to wells in the area, but fractures in the lower part of the Petrified Forest Member are probable pathways for upward flow of water from the Shinarump Member. Most of the mines receive water from surface inflow of rainfall runoff, but ground water also may be transmitted to open pits and drill holes in the subsurface through fractures or along faults in the Petrified Forest Member. Uranium-238 activities in shallow ground water from mines ranged from 150 to 14,000 picocuries per liter. Radionuclide activities in well and spring water were less than in shallow ground water near mines; however, in some samples, radionuclide activities in wells and springs were greater than activities in pit water. Uranium concentrations in leachate samples ranged from 20 to 7,700 micrograms per liter. Batch tests were done with material that was 2.00 millimeters and smaller. The radiochemistry of leachate from coarser material was not determined, and the specific rate and magnitude of radionuclide leaching depends on site-specific conditions that include the amounts of oxygen and organic material present, temperature, spoil mineralogy, and local ground-water composition.

  1. Heat transfer and material temperature conditions in the leading edge area of impingement-cooled turbine vanes

    Science.gov (United States)

    Berg, H. P.; Pfaff, K.; Hennecke, D. K.

    The resultant effects on the cooling effectiveness at the leading edge area of an impingement-cooled turbine vane by varying certain geometrical parameters is described with reference to local internal heat transfer coefficients determined from experiment and temperature calculations. The local heat transfer on the cooling-air side is determined experimentally with the aid of the analogy between heat- and mass transfer. The impingement cooling is provided from an inserted sheet-metal containing a single row of holes. The Reynolds Number and several of the cooling geometry parameters were varied. The results demonstrate the high local resolution of the method of measurement, which allows improved analytical treatment of the leading-edge cooling configuration. These experiments also point to the necessity of not always performing model tests under idealized conditions. This becomes very clear in the case of the tests performed on an application-oriented impingement-cooling configuration like that often encountered in engine manufacture. In conclusion, as an example, temperature calculations are employed to demonstrate the effect on the cooling effectiveness of varying the distances between insert and inner surface of the leading edge. It shows how the effectiveness of the leading edge cooling can be increased by simple geometrical measures, which results in a considerable improvement in service life.

    The use of multiblade slurry sawing to produce silicon wafers from ingots was investigated. The commercially available state of the art process was improved by 20% in terms of area of silicon wafers produced from an ingot. The process was improved 34% on an experimental basis. Economic analyses presented show that further improvements are necessary to approach the desired wafer costs, mostly reduction in expendable materials costs. Tests which indicate that such reduction is possible are included, although demonstration of such reduction was not completed. A new, large capacity saw was designed and tested. Performance comparable with current equipment (in terms of number of wafers/cm) was demonstrated.

    axes, the maximum tensor (and engineering) shear strain, the area strain (dilation), the invariants of the strain tensor, and associated uncertainties. We provide several example triplets of GPS stations that illustrate different crustal-strain environments: rigid-body translation and rotation, extension, contraction and strike-slip. With more than 1100 PBO stations to choose from, students can pursue their interests by exploring crustal strain between many possible triplets of GPS stations. We provide suggestions to extend this material (e.g., analysis of larger areas using Delaunay triangles) and offer relevant literature references so that students can learn how these techniques are used in research. An important part of the development of this resource is the attention paid to assessment of student learning. We hope the resources provided to teachers in support of this curricular module will be an exemplar for them in developing other topics throughout their courses. Teachers interested in serving as beta testers are encouraged to contact the authors.

    Natural and artificial radionuclides and heavy metals in the surface soil of the uranium mining area of Tongliao, China, were measured using gamma spectrometry, flame atomic absorption spectrophotometry, graphite furnace atomic absorption spectrophotometry and microwave dissolution atomic fluorescence spectrometry respectively. The estimated average activity concentrations of (238)U, (232)Th, (226)Ra, (40)K and (137)Cs are 27.53±16.01, 15.89±5.20, 12.64±4.27, 746.84±38.24 and 4.23±4.76Bq/kg respectively. The estimated average absorbed dose rate in the air and annual effective dose rate are 46.58±5.26nGy/h and 57.13±6.45μSv, respectively. The radium equivalent activity, external and internal hazard indices were also calculated and their mean values are within the acceptable limits. The heavy metal concentrations of Pb, Cd, Cu, Zn, Hg and As from the surface soil were measured and their health risks were then determined. Although the content of Cd is much higher than the average background in China, its non-cancer and cancer risk indices are all within the acceptable ranges. These calculated hazard indices to estimate the potential radiological health risk in soil and the dose rate are well below their permissible limit. In addition the correlations between the radioactivity concentrations of the radionuclides and the heavy metals in soil were determined by the Pearson linear coefficient.

    1990-03-01

    This study examined the relationships of nursing curricular program, burnout, and use of coping strategies among 150 randomly selected staff nurses from four hospitals. The instruments used were the frequency dimension of the Maslach Burnout Inventory (Maslach & Jackson, 1981) and the Ways of Coping (Revised) (Folkman & Lazarus, 1985). Discriminant analysis demonstrated that (a) diploma graduates differed from associate-degree graduates in their greater experience of Emotional Exhaustion (p less than .05) and (b) baccalaureate-degree graduates differed from associate-degree graduates in their greater use of Planful Problem Solving and Confronting Coping (p less than .05). Recommendations include additional research to discover relevant factors for the greater experience of Emotional Exhaustion among diploma graduates. If related to perceptions of limited career mobility due to the lack of a baccalaureate degree, expansion of educational opportunities is indicated. Another recommendation is curricular incorporation of content on burnout and coping.

    Full Text Available Lack of preparation in science leads to high rates of attrition among science, technology, engineering, and mathematics (STEM majors, even among students who are highly oriented toward STEM. Using data for twenty-seven countries from the 2006 Program for International Student Assessment, we compare the United States with other industrialized countries in terms of fifteen-year-olds’ science achievement and their expectations to focus on STEM in the future. The United States trails most countries in the mean science achievement of the general student population and among students expecting to pursue STEM majors or careers. Lack of curricular standardization in the United States is related to this lower science achievement. Countries with higher curricular standardization exhibit higher average science achievement scores; science achievement and students’ future orientation toward science are also better aligned in these countries. We discuss the implications of these findings for American colleges and universities as they seek to reduce student attrition in STEM fields.

    Full Text Available The school, as the institution whose basic activity is education, has an important role in preventing the emergence of undesired and stimulating desired forms of behaviour of the students. In the realization of this role it relies on legal and curricular documents which define the direction of the preventing acting of school. Starting from this, the article describes and analyses laws and other legal documents in the field of education which cover in more detail the issues of violence prevention, as well as curricular documents which are developed on the school level. The obtained results show that legal provisions should define the issues of the prevention of undesirable behaviours of students more clearly. The analysis of the curricular documents showed that the planned preventive measures and activities are not sufficiently accorded with the needs of different categories of students, as well as the fact that important participants in the educational process are not sufficiently included in the process of planning and realization of the preventive activities of the school.

    The relationship between physical activity and health status has been thoroughly investigated in several studies, while the relation between physical activity and socio-economic status (SES) is less investigated. The aim of this study was to measure the extra-curricular physical activity of adolescents related to the socio-economic status (SES) of their families. The survey was carried out by submitting an anonymous questionnaire to junior high school students in the following Regions: Lazio, Abruzzo, Molise, Campania, Puglia, during the school year 2002-2003. Extra-curriculum physical activity was evaluated considering whether or not present and hours of activity weekly conducted. 2411 students agreed to participate in the study. Participants were 1121 males (46.5%) and 1290 females (53.5%), aged between 11 and 17 years (median age: 12 years). 71.1% of the students reported to practice extra-curricular physical activity. Parents' educational levels and work activities play an important role in predicting students' physical activity, with the more remunerative activities and higher educational levels being more predictive. The results confirm the relationship between adolescents' physical activity and their families' SES. In particular, a positive relationship between participation in extra-curricular physical activity and their families high SES was found. These data will be useful for school administrators and for politicians in order to reduce the gap between adolescents from the least and most disadvantaged families.

    1998-10-01

    In 1992, the four medical schools in North Carolina and that state's dental school initiated a four-year project to more thoroughly integrate content about substance abuse into their curricula. The project was based on the premise that medical schools are failing to provide their students with adequate training about substance abuse issues, yet substance abuse is a large and growing source of health problems nationwide. While the authors indicate in broad ways the kinds of curricular content that the project sought, in this article they concentrate on the processes by which key faculty, administrators, and staff members from all the schools worked together in the curriculum development process, with each school tailoring the project's findings to the needs of its own students. Phase I of the project focused on the selection and orientation of the key faculty and members of the working committee at each institution, and garnering institutional support. Phase II focused on the development by key faculty of the project's philosophy, goals, and objectives; conducting needs assessment and curriculum analysis at each school; and identifying the content needed. During Phase III, project participants refined the needed content and integrated it, in individual ways, into each school's curriculum. Some (but not enough) evaluation of these curricular implementations was done. The authors highlight the lessons learned, both positive and negative, in hopes that these will be useful to other educators who wish to design, implement, and institutionalize substance-abuse curricular content.

    Medical education can have significant negative effects on the well-being of medical students. To date, efforts to improve student mental health have focused largely on improving access to mental health providers, reducing the stigma and other barriers to mental health treatment, and implementing ancillary wellness programs. Still, new and innovative models that build on these efforts by directly addressing the root causes of stress that lie within the curriculum itself are needed to properly promote student wellness. In this article, the authors present a new paradigm for improving medical student mental health, by describing an integrated, multifaceted, preclinical curricular change program implemented through the Office of Curricular Affairs at the Saint Louis University School of Medicine starting in the 2009-2010 academic year. The authors found that significant but efficient changes to course content, contact hours, scheduling, grading, electives, learning communities, and required resilience/mindfulness experiences were associated with significantly lower levels of depression symptoms, anxiety symptoms, and stress, and significantly higher levels of community cohesion, in medical students who participated in the expanded wellness program compared with those who preceded its implementation. The authors discuss the utility and relevance of such curricular changes as an overlooked component of change models for improving medical student mental health.

The main objective is to emphasize upon submission of the work that we do in our teaching practice in the mentioned disciplines, the importance of linking the theory and the practice in training of teachers so that the teaching in the university it is not decontextualized but enriched with the issues of everyday school life. In this sense, we address, initially, the aspects of the Curricular training as a mediator link of the learning, of the articulation of the curriculum and of the practices and, in this view, as a productive conduit between the university and the basic education, stressing the need for the reception of the contribution that each institutions within its specificity, must provide in the training courses. In sequence, we present aspects of the structure of the work we do with our students in Early Childhood Education Curricular Training. Finally, are detailed the aspects of a Didactics for the teachers of early childhood education and for the early years of Fundamental Education, focusing on narratives of in-service teachers on their experiences teaching in search of new systematization of pedagogical practice and on by own teachers.

The article describes critically and analytically every step of the curricular stage, especially the classes with the themes: reproduction and sexuality. The classes were taught to elementary students in State College St. Bernadete in Goiânia-GO. To facilitate the process of teaching and learning the trainees divided the themes into subtopics, and several teaching resources were developed for each subtopic. The research was descriptive and exploratory, using interviews with school students, teachers, supervisors and college students to collect data that allowed assessing the success of the teaching methodologies applied by the teachers in training. The field diaries of the trainees were also used to compose the analysis. Through the statements of the participants, it is considered that the methods achieved their goal in clarifying the issues. The resources used not only brought understanding, but encouraged the participation of the students. The article has been organized according to the steps of the curricular stage and it exposes all the impressions of the supervising teachers, school students and undergraduates during the internship, highlighting, comments, concerns, planning and execution process of the activities.

Data collected were transferred to Predictive Analytics Software, Version 18. Global and domain scores were assessed with the Wilcoxon Rank-Sum Test. Percentage agreement, disagreement and uncertainty were assessed by the z-test for proportion. Results: There were no significant differences between the total DREEM scores of faculty (139/200 and students (135/200. The faculty perceived that the students were experiencing significantly more positive learning as indicated by the domain score of “Students' Perceptions of Learning”. Proportions of agreement between faculty and students showed that more faculty members than students perceived the need for increased feedback to students and a greater emphasis on long term learning. Conclusion: The study showed that the faculty and students had similar perceptions about the student experiences in the integrated curriculum. Areas necessitating remedial measures were the need for faculty to learn constructive feedback techniques and an emphasis on long term learning in the new curriculum.

Nevertheless, the processes of globalization and generalization of the technologies of the information and the communication, and the relation of the itc with the mass comes up, have provoked that this interest increases between different international institutions. The education does not remain foreign to this subject-matter, on the contrary, it is worried for the influence of the mass media in the processes of education and learning of the pupils. But: until point the curriculum shows this worry? In this article we analyze the presence of the media competence, according to the dimensions established by Ferrés (2007, in the objectives of stage and area of the autonomous regions of global form. The results show the presence of this competence in the educational intentions, but it is necessary to systematize and to show explicitly the relation between the education and the mass media.

    Assessment and monitoring of soil organic matter (SOM) quality are important for understanding SOM dynamics and developing management practices that will enhance and maintain the productivity of agricultural soils. Visible and near-infrared (Vis-NIR) diffuse reflectance spectroscopy (350-2500 nm) has received increasing attention over the recent decades as a promising technique for SOM analysis. While heterogeneity of sample sets is one critical factor that complicates the prediction of soil properties from Vis-NIR spectra, a spectral library representing the local soil diversity needs to be constructed. The study area, covering a surface of 927 km2 and located in Yujiang County of Jiangsu Province, is characterized by a hilly area with different soil parent materials (e.g., red sandstone, shale, Quaternary red clay, and river alluvium). In total, 232 topsoil (0-20 cm) samples were collected for SOM analysis and scanned with a Vis-NIR spectrometer in the laboratory. Reflectance data were related to surface SOM content by means of a partial least square regression (PLSR) method and several data pre-processing techniques, such as first and second derivatives with a smoothing filter. The performance of the PLSR model was tested under different combinations of calibration/validation sets (global and local calibrations stratified according to parent materials). The results showed that the models based on the global calibrations can only make approximate predictions for SOM content (RMSE (root mean squared error) = 4.23-4.69 g kg-1; R2 (coefficient of determination) = 0.80-0.84; RPD (ratio of standard deviation to RMSE) = 2.19-2.44; RPIQ (ratio of performance to inter-quartile distance) = 2.88-3.08). Under the local calibrations, the individual PLSR models for each parent material improved SOM predictions (RMSE = 2.55-3.49 g kg-1; R2 = 0.87-0.93; RPD = 2.67-3.12; RPIQ = 3.15-4.02). Among the four different parent materials, the largest R2 and the smallest RMSE were

In the new curriculum, adapted to the European Higher Education Area and valid throughout the European continent, a Final Degree Work (TFG was introduced to the last semester of training, which must demonstrate a received comprehensive training in all subjects. We planned a TFG model in which students interrelate knowledge, professional practice and research. This type of TFG is based on the Emergent Educational Model that we have elaborated. In the current course we have carried out and analyzed four examples in which ethnomathematics is introduced as a foundation, microprojects focusing on different cultural signs are elaborated, and the interrelationship of the various sciences are reflected upon, creating awareness that research is a necessary element in teacher education. We describe the MED model of teacher education, the didactic teaching construct called micro-project, and the type of TFG designed, along with four examples thereof.

    Previous research has suggested that transformative learning can be fostered in higher education by creating active learning experiences that are directly related to content taught, are personally engaging, and can stimulate reflection. The aim of this qualitative study was to assess changes experienced by students in an e-learning dental hygiene degree completion program beyond attainment of competence-changes that may be described as transformative learning. The data used were transcripts of focus groups that had been conducted with each of the first five cohorts of students to graduate from the program; a total of 30 of the 42 students in the five cohorts (71%) participated. Using their previously developed Transformation Rubric for Engaged Learning, the authors categorized focus group data to identify changes in students' confidence, pride, skills, perceptions of the world, and personal identity at the transformative and nontransformative levels. Every participant reported at least one change; overall, the students averaged 8.3 changes. The vast majority (84%) of these changes were transformative. Middle-performing students showed a disproportionately higher rate of transformational changes in the areas of confidence and pride. The e-learning program appeared to have had a significant transformative impact on students, but additional research on the effect on middle-performing students is warranted.

    Full Text Available No período da reforma das décadas de 1980 e 1990, a idéia das políticas curriculares descentralizadas tornou-se central no discurso educacional. O Estado poderá usar o discurso da descentralização para defender mais autonomia e responsabilidade, tal como as forças de mercado poderão empregá-lo para orientar os seus objetivos em relação às escolas. Neste artigo pretendemos identificar uma série de diferentes significados para a palavra descentralização, argumentando que o currículo é um processo intencional e prático em que os principais atores são os professores e os alunos. O ponto central é como caminharmos fora das linhas. A provável resposta introduz a centralidade da escola sem minimizar a importância das questões curriculares.The idea of decentralization became central to educational discourse during the period of reform of the late 1980s and the 1990s. The State can use the discourse of decentralization to argue in favor of greater autonomy and responsibility, just as market forces can use it to attain their objectives in regard to schools. In this article our purpose is to identify a number of different meanings of the term decentralization, arguing that decisions regarding curricula are intentional and practical processes in which students and teachers are the main actors. The key question is how to move ahead off the beaten path. The probable answer will be based on the centrality of the school without minimizing the importance of curriculum-related issues.

    Large surface area and good structural stability, for porous carbons, are two crucial requirements to enable the constructed supercapacitors with high capacitance and long cycling lifespan. Herein, we successfully prepare porous carbon with a large surface area (3175 m2 g-1) and an ultrahigh carbon purity (carbon atom ratio of 98.25%) via templating carbonization coupling with KOH activation. As-synthesized MTC-KOH exhibits excellent performances as supercapacitor electrode materials in terms of high specific capacitance and ultrahigh cycling stability. In a three electrode system, MTC-KOH delivers a high capacitance of 275 F g-1 at 0.5 A g-1 and still 120 F g-1 at a high rate of 30 A g-1. There is almost no capacitance decay even after 10,000 cycles, demonstrating outstanding cycling stability. In comparison, pre-activated MTC with a hierarchical pore structure shows a better rate capability than microporous MTC-KOH. Moreover, the constructed symmetric supercapacitor using MTC-KOH can achieve high energy densities of 8.68 Wh kg-1 and 4.03 Wh kg-1 with the corresponding power densities of 108 W kg-1 and 6.49 kW kg-1, respectively. Our work provides a simple design strategy to prepare highly porous carbons with high carbon purity for supercapacitors application.

We invited 16 final year medical students posted in the Department of Medicine to record their emotional experiences during a 6-week posting. Freedom to abstain without prejudice was emphasized, yet all 16 students complied. According to the principle of grounded theory, the entries were grouped into 8 themes: (i) doctor-patient relationship; (ii) personal inadequacy; (iii) empathy; (iv) communication skills; (v) doctor's competence; (vi) patient behaviour; (vii) hospital practices; and (viii) personal feelings. There were 179 entries which were evaluable under the above categories, with no significant gender differences. Based on the entries, the following curricular suggestions were made: (i) use of diaries by medical students to express their emotional reactions and make value judgements, followed by guided discussion by experienced facilitators; (ii) introduction of communication skills courses at appropriate points to enhance Interview skills, empathetic listening, conflict resolution and breaking bad news; (iii) encourage reflection on healthcare delivery and its inequities and suggest methods of dealing with individual patients; and (iv) use of positive feedback and encouragement by faculty. Conclusions. Reflective journal writing by medical students in India gives valuable insights into improving communication skills and professionalism. Appropriate curricular changes should be made to meet the challenges posed by the existing healthcare system.

El segundo, propiciado por la reflexión sobre estas prácticas en un grupo de estudio sobre diseño curricular en el Centro de Evaluación Académica de la misma Universidad. Tener el espacio para conjugar experiencia y reflexión permitió retomar labores esenciales que las y los docentes pueden realizar para transformar el currículum, si se parte de una comprensión compleja, histórica y contextual de este. Se concluye, en este sentido, que el diseño y desarrollo curricular son dos momentos inseparables, donde el cuerpo docente puede tener una participación activa y crítica. El análisis realizado, fuertemente imbricado al referente de la propia práctica, se concreta en una propuesta de acciones posibles, cuya viabilidad aumenta si el profesorado cuenta con la formación necesaria, y con una actitud permanente de autocrítica y reflexión.Abstract: This essay was elaborated by the combination of two different moments; the first one related with the experience of the author in his labor as a university educator, and as a integrant and coordinator of the Curriculum Commission of the Social Work School at the University of Costa Rica.

  7. Mental Discipline, Curricular Reform, and the Decline of U.S. Astronomy Education, 1893-1920

    Science.gov (United States)

    Marché, Jordan D., II

    Nineteenth-century astronomy education rested on a powerful rationale of support within American liberal arts colleges and high schools. Descriptive astronomy was widely regarded as suitable for improving a student's "mental discipline." But the collapse of mental discipline pedagogy, along with concurrent efforts to standardize and reform secondary-level curricula, were responsible for a significant post-1900 decline in astronomical teaching. As a result, astronomy education was not broadly reinstated into secondary curricula until after the launch of Sputnik in 1957. This report demonstrates that changing relationships between disciplinary specialties and pedagogical theories provide no guarantee of sustained curricular success--a conclusion equally relevant to today's science educators.

    In 2009, to support an evaluation of the feasibility of reopening the Pearce Creek Dredge Material Containment Area (DMCA) in Cecil County, Maryland, for dredge-spoil disposal, the U.S. Geological Survey (USGS) began to implement a comprehensive study designed to improve the understanding of the hydrogeologic framework, hydrology, and water quality of shallow aquifers underlying the DMCA and adjacent communities, to determine whether or not the DMCA affected groundwater quality, and to assess whether or not groundwater samples contained chemical constituents at levels greater than maximum allowable or recommended levels established by the U.S. Environmental Protection Agency Safe Drinking Water Act. The study, conducted in 2010-11 by USGS in cooperation with the U.S. Army Corps of Engineers, included installation of observation wells in areas where data gaps led earlier studies to be inconclusive. The data from new wells and existing monitoring locations were interpreted and show the DMCA influences the groundwater flow and quality. Groundwater flow in the two primary aquifers used for local supplies-the Magothy aquifer and upper Patapsco aquifer (shallow water-bearing zone)-is radially outward from the DMCA toward discharge areas, including West View Shores, the Elk River, and Pearce Creek Lake. In addition to horizontal flow outward from the DMCA, vertical gradients primarily are downward in most of the study area, and upward near the Elk River on the north side of the DMCA property, and the western part of West View Shores. Integrating groundwater geochemistry data in the analysis, the influence of the DMCA is not only a source of elevated concentrations of dissolved solids but also a geochemical driver of redox processes that enhances the mobilization and transport of redox-sensitive metals and nutrients. Groundwater affected by the DMCA is in the Magothy aquifer and upper Patapsco aquifer (shallow water-bearing zone). Based on minimal data, the water quality

    2013-10-22

    We report the development of Co9S8 nanocrystals as a cost-effective cathode material that can be readily combined with spraying techniques to fabricate large-area dye-sensitized solar cell (DSSC) devices and can be further connected with series or parallel cell architectures to obtain a relatively high output voltage or current. A gram-scale synthesis of Co9S8 nanocrystal is carried out via a noninjection reaction by mixing anhydrous CoCl2 with trioctylphosphine (TOP), dodecanethiol and oleylamine (OLA) at 250 °C. The Co9S8 nanocrystals possess excellent catalytic ability with respect to I(-)/I3(-) redox reactions. The Co9S8 nanocrystals are prepared as nanoinks to fabricate uniform, crack-free Co9S8 thin films on different substrates by using a spray deposition technique. These Co9S8 films are used as counter electrodes assembled with dye-adsorbed TiO2 photoanodes to fabricate DSSC devices having a working area of 2 cm(2) and an average power conversion efficiency (PCE) of 7.02 ± 0.18% under AM 1.5 solar illumination, which is comparable with the PCE of 7.2 ± 0.12% obtained using a Pt cathode. Furthermore, six 2 cm(2)-sized DSSC devices connected in series output an open-circuit voltage of 4.2 V that can power a wide range of electronic devices such as LED arrays and can charge commercial lithium ion batteries.

    Mercury has a strong environmental impact since both its organic and inorganic forms are toxic, and it represents a pollutant of global concern. Liquid Hg is highly volatile and can be released during natural and anthropogenic processes in the hydrosphere, biosphere and atmosphere. In this study, the distribution of Gaseous Elemental Mercury (GEM) and the total and leached mercury concentrations on paint, plaster, roof tiles, concrete, metals, dust and wood structures were determined in the main buildings and structures of the former Hg-mining area of Abbadia San Salvatore (Siena, Central Italy). The mining complex (divided into seven units) covers a surface of about 65 ha and contains mining structures and managers' and workers' buildings. Nine surveys of GEM measurements were carried out from July 2011 to August 2015 for the buildings and structures located in Units 2, 3 and 6, the latter being the area where liquid mercury was produced. Measurements were also performed in February, April, July, September and December 2016 in the edifices and mining structures of Unit 6. GEM concentrations showed a strong variability in time and space mostly depending on ambient temperature and the operational activities that were carried out in each building. The Unit 2 surveys carried out in the hotter period (from June to September) showed GEM concentrations up to 27,500 ng·m(-3), while in Unit 6, they were on average much higher, and occasionally, they saturated the GEM measurement device (>50,000 ng·m(-3)). Concentrations of total (in mg·kg(-1)) and leached (in μg·L(-1)) mercury measured in different building materials (up to 46,580 mg·kg(-1) and 4470 mg·L(-1), respectively) were highly variable, being related to the edifice or mining structure from which they were collected. The results obtained in this study are of relevant interest for operational cleanings to be carried out during reclamation activities.

    2014-06-01

    The main purpose of this study was to evaluate the differences in adolescents´ objective physical activity levels and perceived effort in physical education, school recess, and extra-curricular organized sport by motivational profiles in physical education. A sample of 102 students 11-16 yr. old completed a self-report questionnaire assessing self-determined motivation toward physical education. Subsequently, students' objective physical activity levels (steps/min., METs, and moderate-to-vigorous physical activity) and perceived effort were evaluated for each situation. Cluster analysis identified a two-cluster structure: "Moderate motivation toward physical education profile" and "High motivation toward physical education profile." Adolescents in the second cluster had higher physical activity and perceived effort values than adolescents in the first cluster, except for METs and moderate-to-vigorous physical activity in extra-curricular sport. These results support the importance of physical education teachers who should promote self-determined motivation toward physical education so that students can reach the recommended physical activity levels.

Underscoring the discursive nature as constituting curricular production supports the affirmation that the discourse is not a representation/manifestation of structures that are its basis, but an articulatory process. For that reason, in that study the concept of policy and the conceptions that support its formulations rooted in that understanding are presented, highlighting the contribution of Laclau and Mouffe, after examining central categories – discourse, hegemony and articulatory practices – which, for those authors, outline the perspective of policy defended. In that sense, the process of policy production is seen as an articulatory practice and it is argued that the analyses of curriculum policies are viewed as a conRoteiro,Joaçaba, v. 35, n. 2, p. 231-250, jul./dez. 2010 247Um novo olhar sobre o sentido de política...tingent, conflicting, discursive and dialogical action that enables the subjects to take up positions within the identitary discourses, in a democratic-pluralist universe complete with struggles and negotiations.

Eleven portfolios were analyzed, and the narratives found were descriptive, reflective and descriptive, reflective and dialogic, and critical with subsequent thematic analysis. We identified four types of narratives. Reflections were focused around three thematic categories: an analysis of the internship’s field of work; assimilation and analysis of the nursing professional’s work; and what was learned throughout the Supervised Curricular Internship. The relevant aspects of the internship experience were apprehended and systematized through the portfolios, although more in-depth critical reflection is needed. The analysis of narrative types presented by students can contribute to guiding the process of nursing training evaluation towards critical reflection. doi: 10.5216/ree.v16i3.25691.

    Full Text Available As the cultural and linguistic diversity continues to increase in Florida s K-12 public school population, the demand for teachers trained to address their unique needs becomes paramount. Previously a responsibility of Florida s school districts, ESOL(English for Speakers of Other Languages training has been delegated to colleges of education per state mandate. This mandate requires that graduates of initial teacher certification programs in the state s universities demonstrate competency in all of the 25 Florida Performance Standards for Teachers of English for Speakers of Other Languages. In order to satisfy this charge, colleges of education in Florida are following a variety of training models: stand-alone courses, curricular infusion, or a combination of the two. A large, metropolitan university in Central Florida has developed an integrated model consisting of two stand-alone courses, field experience integration of the standards, and curricular infusion of ESOL standards via on-lone modules in methods courses. The authors, who teach methods courses in which such infusion has been recently effected, surveyed their students to obtain feedback regarding the modules, the results of which are discussed in this paper.

    Ongoing curricular renewal is a necessary phenomenon in nursing education to align learning with ever-changing professional practice demands. The McMaster Mohawk Conestoga BScN Program in Hamilton, Ontario, Canada recently engaged in a comprehensive curriculum renewal. The purpose of this study was to evaluate the impact of curricular changes on students' deep learning. Faculty perceptions about student learning outcomes during final year clinical placements were gathered through a combination of individual interviews and focus groups using Interpretive Descriptive qualitative research methodology. Twenty five faculty members who supervised BScN students in clinical placements before and after curriculum renewal shared perceptions of changes in students' overall performance. The chosen clinical learning outcomes were: changes in students' performance related to person-centred care, clinical reasoning and judgment, pathophysiology, and evidence-informed decision-making. Faculty described three major themes in students' performance 1) pulling it all together, 2) seeing the whole person, and 3) finding their nursing voices. This reflected a shift to person-centred care, increasing professional confidence, and improved clinical reasoning and judgment and no changes to integrating pathophysiology or evidence-informed decision-making. In this study curriculum renewal provided an excellent starting point for the scholarship of teaching and learning within nursing education. Copyright © 2016 The Authors. Published by Elsevier Ltd..

    The authors describe the process by which a curriculum was developed to introduce complementary and alternative medicine topics at multiple levels from health professional students to faculty, as part of a five-year project, funded by a grant from the National Institutes of Health, at the University of Texas Medical Branch in Galveston, Texas, from 2001 to 2005. The curriculum was based on four educational goals that embrace effective communication with patients, application of sound evidence, creation of patient-centered therapeutic relationships, and development of positive perspectives on wellness. The authors analyze the complex and challenging process of gaining acceptance for the curriculum and implementing it in the context of existing courses and programs. The developmental background and context of this curricular innovation at this institution is described, with reference to parallel activities at other academic health centers participating in the Consortium of Academic Health Centers for Integrative Medicine. The authors hold that successful curricular change in medical schools must follow sound educational development principles. A well-planned process of integration is particularly important when introducing a pioneering curriculum into an academic health center. The process at this institution followed six key principles for successful accomplishment of curriculum change: leadership, cooperative climate, participation by organization members, politics, human resource development, and evaluation. The authors provide details about six analogous elements used to design and sustain the curriculum: collaboration, communication, demonstration, evaluation, evolution, and dissemination.

    With the goal to facilitate cultural competency development of students enrolled in graduate-level health professional education, this study examined the effectiveness of a curricular program guided by the Intercultural Developmental Continuum (IDC) as measured by the Intercultural Developmental Inventory (IDI). The IDI was administered to 17 occupational therapy (OT) students and a control group of 25 non-OT health professional students upon matriculation into their respective programs of graduate study and again upon completion of 3 years of study. OT students participated in a cultural curricular design guided by the IDC, while the control group participated in cultural study not guided by the IDC. Though OT students did not show a significant change in overall developmental orientation mean scores from pre-test to post-test (t = 0.847, p = 0.41), the results indicate that the designed intercultural curriculum increased intercultural competence among those OT students who began their program with the monocultural mindset of polarization (an "us vs. them" evaluative viewpoint) and moved to the interculturally transitional mindset of minimization (recognizing cultural commonalities and elimination of the "us vs. them" mindset). The control group showed a significant decrease in developmental orientation mean scores at post-test (t = 6.1, p competency of OT students, appears to have mitigated a decrease in competence. Results suggest that the cultural challenges that students face appear to be considerable and, without targeted, integrated intercultural preparation, can overwhelm new health professionals' intercultural capability.

    A mixed-methods evaluation was conducted to study learner attitudes and knowledge about clinical pathology across a curricular change that instituted a stand-alone clinical pathology course in place of content within a previously integrated pathology course structure. Groups of pre- and post-change students were assessed three times across the two semesters leading up to graduation. At each time, rank-ordered and open-ended response items probed attitudes, and multiple-choice items assessed knowledge. Data about student clinical pathology performance were also collected from clinical pathology instructors and supervising clinicians. Student rank-ordered items were evaluated by factor analysis; resulting factor-scale scores, multiple-choice scores, and rank responses from study cohorts were statistically assessed between groups and within each group over time. Intraclass correlations were calculated for the coding of student open-ended responses, and all coded responses were compared among groups. Analysis revealed that students in the revised curriculum had greater satisfaction with their training and greater confidence in data interpretation compared to students without exposure to an independent clinical pathology course. Although differences in knowledge of clinical pathology were not detected, it was also apparent that the independent clinical pathology course filled a student-perceived curricular need without raising criticisms related to diminished integration with anatomic pathology. Secondary study outcomes included formative feedback for course improvement, evidence of clerkship efficacy, and baseline data for further studies.

Essas políticas produzem efeitos importantes para o campo educacional, com ênfase no currículo, na gestão e no trabalho docente. Por meio de estratégias de avaliação, tipicamente gerencialistas, o Estado tem obtido êxito na padronização curricular, na implantação de políticas de formação docente e na submissão da escola e da educação aos interesses do mercado. Os modos de gestão, insistentemente mostrados como a solução para a educação, chegam às escolas como formas estranhas de administração e a cada dia mais se mostram ineficientes para enfrentar os problemas escolares. Contudo, essas políticas de regulação continuam sendo a tônica das políticas de Estado para a educação.

    To assess the image quality and diagnostic accuracy of 320-row area detector CT (320-ADCT) coronary angiography using 40 mL of contrast material in comparison with 60-mL protocol. This retrospective study included 183 patients who underwent 320-ADCT coronary angiography using 40 mL of contrast and additional 183 sex- and body mass index-matched patients using 60 mL of contrast constituting the control group. Both groups used the same 5-mL/sec injection rate. Quantitative image quality measurements and diagnostic accuracies were calculated and compared. Mean attenuation and contrast-to-noise ratio (CNR) at the aorta and all coronary arteries were lower in the 40-mL group than in the 60-mL group (all, p < 0.05), except for the CNR at proximal coronary arteries at 100 kVp (p = 0.073). However, the proportion of coronary segments with vessel attenuation >250 HU was not different between groups (all, p > 0.05), except for distal coronary arteries at 80 kVp (p = 0.001). Furthermore, there were no differences in per-patient and per-segment diagnostic accuracies between the groups (all, p > 0.05). 320-ADCT coronary angiography using 40 mL of contrast showed image quality and diagnostic accuracy comparable to the 60-mL protocol, demonstrating the clinical feasibility of lowering the risk of contrast-induced nephropathy through contrast volume reduction.

  3. Fate and transport processes controlling the migration of hazardous and radioactive materials from the Area 5 Radioactive Waste Management Site (RWMS)

    Desert vadose zones have been considered as suitable environments for the safe and long-term isolation of hazardous wastes. Low precipitation, high evapotranspiration and thick unsaturated alluvial deposits commonly found in deserts make them attractive as waste disposal sites. The fate and transport of any contaminant in the subsurface is ultimately determined by the operating retention and transformation processes in the system and the end result of the interactions among them. Retention (sorption) and transformation are the two major processes that affect the amount of a contaminant present and available for transport. Retention processes do not affect the total amount of a contaminant in the soil system, but rather decrease or eliminate the amount available for transport at a given point in time. Sorption reactions retard the contaminant migration. Permanent binding of solute by the sorbent is also possible. These processes and their interactions are controlled by the nature of the hazardous waste, the properties of the porous media and the geochemical and environmental conditions (temperature, moisture and vegetation). The present study summarizes the available data and investigates the fate and transport processes that govern the migration of contaminants from the Radioactive Waste Management Site (RWMS) in Area 5 of the Nevada Test Site (NTS). While the site is currently used only for low-level radioactive waste disposal, past practices have included burial of material now considered hazardous. Fundamentals of chemical and biological transformation processes are discussed subsequently, followed by a discussion of relevant results.

    Bedside teaching is an important element of undergraduate medical education. However, the impact of curricular course structure on student outcome needs to be determined. This study assessed changes in fourth-year medical students' evaluations of clinical teaching sessions before and after the introduction of a new course format. The curricular structure of bedside teaching sessions in cardiology was modified without changing the amount of teaching time. Clinical teachers were instructed about the new teaching format and learning objectives. The new format implemented for adult but not paediatric cardiology sessions was piloted with 143 students in winter 2007/08. By computing effect sizes, evaluation results were compared to data obtained from 185 students before the intervention. Significant rating increases were observed for adult cardiology teaching sessions (Cohen's d = 0.66) but not paediatric cardiology sessions (d = 0.22). In addition to improving the structure and organization of the course, the intervention significantly impacted on students' perceptions of their learning outcome regarding practical skills (d = 0.69). Minimal curricular changes combined with basic faculty development measures significantly increase students' perception of learning outcome. Curricular structure needs to be considered when planning bedside teaching sessions in medical undergraduate training.

    Full Text Available Neste texto tecemos algumas considerações sobre o contexto em que ocorrem os debates acerca das Diretrizes Curriculares para o ensino superior brasileiro, especialmente aquelas referentes à área de Educação Física. Sugerimos que as Diretrizes Curriculares de Educação Física, formuladas pela comissão de especialistas, designada pelo MEC, têm sido referenciadas em confronto com as perspectivas apontada para a universidade brasileira atualmente, em particular para a formação de professores. Relatamos as contribuições da FEF/UFG para este debate, bem como justificamos os pontos essenciais de um documento anterior, não publicado, em que se apresentam posições sobre currículo e formação de professores de Educação Física na atualidade. Basicamente nos opomos aos projetos do Banco Mundial, FMI e MEC/FHC e seus interesses mercadológicos e de preparação restrita para ao mercado de trabalho, por entendermos que a formação de professores deve ocorrer no âmbito da universidade pública, gratuita e de qualidade social, e onde demandas sociais relevantes se constituam no maior foco de interesse. PALAVRAS-CHAVE: Educação Física, Diretrizes Curriculares, formação de professores. In this paper e make considerations about the curriculum diretrixes for universities, mainly those related to Physical Education. We believe that the diretrixes, established by a commission of experts, need discussion. We oppose to Worsd-Wide Bank, IMF and MEC due to their merchandising interests. We understand that the formation of teachers needs to take place in a public, free and socially qualified university. This paper also presents FEF’s contrubutions to this discussion, extracted from a document (not published yet. Our points of view concerning curriculum and tracher’s graduation are discussed in detail.

    Bisesi, Erica

    2008-01-01

    Sound is a preferred context to build foundations on wave phenomena, one of the most important disciplinary referents in physics. It is also one of the best-set frameworks to achieve transversality, overcoming scholastic level and activating emotional aspects which are naturally connected with every day life, as well as with music and perception. Looking at sound and music by a transversal perspective - a border-line approach between science and art, is the adopted statement for a teaching proposal using meta-cognition as a strategy in scientific education. This work analyzes curricular proposals on musical acoustics, planned by prospective secondary-school teachers in the framework of a Formative Intervention Module answering the expectation of making more effective teaching scientific subjects by improving creative capabilities, as well as leading to build logical and scientific categorizations able to consciously discipline artistic activity in music students. With this aim, a particular emphasis is given ...

    2013-08-01

    An exploratory, qualitative study with the objective of analyzing repercussions of the supervised curricular internship in the development of the ethical dimension of competency in undergraduate nursing students. Semistructured interviews were performed with 28 students, professors and nurse preceptors of a public institution of higher education in the state of São Paulo, during the period of October of 2010 to March of 2011. The empirical result was subjected to the technique of discourse analysis and resulted in the empirical categories: preservation of autonomy; social responsibility and respect in interpersonal relations in health care delivery and in the teaching - learning process; treatment and care from the ethical dimension; and, public responsibility and social justice. It was concluded that the phase that uses problematization as a method of teaching and learning provides critical reflection about professional practice in the services and system of health.

  15. Preparing Students to Take Responsibility for Learning: The Role of Non-Curricular Learning Strategies

    Directory of Open Access Journals (Sweden)

    Carpenter, Jeffrey Paul

    2013-11-01

    Full Text Available Standardized test-based accountability measures often result in overemphasis on knowing facts and cast students into passive roles. Such schooling yields neither the learning nor the learners the modern world requires and can exhaust and demoralize teachers. We assert that students must assume greater responsibility for their learning in order to attain deep understanding and transferable skills that benefit them throughout their lives. Curriculum and instruction must therefore pay greater attention to developing skills that allow students to take such ownership of their learning. We identify and discuss three foundational skills that enable students to assume more responsibility for learning: self-regulation, collaboration, and academic mindsets. After reviewing current research on factors contributing to these non-curricular learning skills and exploring their importance within school contexts and beyond, we discuss the need for more classroom-based research on interventions aimed at their development.

    2013-01-01

    We present outcomes from curricular changes made to an introductory calculus-based physics course whose audience is primarily life science majors, the majority of whom plan to pursue post-baccalaureate studies in medical and scientific fields. During the 2011-12 academic year, we implemented a "Physics of the life sciences" curriculum centered on a draft textbook that takes a novel approach to teaching physics to life science majors. In addition, substantial revisions were made to the homework and hands-on components of the course to emphasize the relationship between physics and the life sciences and to help the students to learn to apply physical intuition to life science-oriented problems. Student learning and attitudinal outcomes were assessed both quantitatively, using standard physics education research instruments, and qualitatively, using student surveys and a series of post-semester interviews. Students experienced high conceptual learning gains, comparable to other active learning-based physics cour...

  20. Open Source Physics: Code and Curriculum Material for Teachers, Authors, and Developers

    Science.gov (United States)

    Christian, Wolfgang

    2004-03-01

    The continued use of procedural languages in education is due in part to the lack of up-to-date curricular materials that combine science topics with an object-oriented programming framework. Although there are many resources for teaching computational physics, few are object-oriented. What is needed by the broader science education community is not another computational physics, numerical analysis, or Java programming book (although such books are essential for discipline-specific practitioners), but a synthesis of curriculum development, computational physics, computer science, and physics education that will be useful for scientists and students wishing to write their own simulations and develop their own curricular material. The Open Source Physics (OSP) project was established to meet this need. OSP is an NSF-funded curriculum development project that is developing and distributing a code library, programs, and examples of computer-based interactive curricular material. In this talk, we will describe this library, demonstrate its use, and report on its adoption by curriculum authors. The Open Source Physics code library, documentation, and sample curricular material can be downloaded from http://www.opensourcephysics.org/. Partial funding for this work was obtained through NSF grant DUE-0126439.
