    Policy changes at the federal and state level are endeavoring to improve student achievement at schools serving children from lower-SES homes. One important strategy is the focus on using evidence-based core reading curricula to provide a consistent framework for instruction across schools. However, rarely have these curricula undergone rigorous comparative testing. Therefore, the purpose of this study was to compare the effects of six core reading curricula on oral reading fluency growth, while appraising whether these effects differ by grade level and for children living in lower socioeconomic (SES) households. Over 30,000 students in first through third grade Florida Reading First classrooms comprise this academically and economically diverse cross-sectional. Hierarchical Linear Modeling was used to model latent growth curves for students' reading fluency scores over the school year. Growth curves revealed differences across curricula as well as between students of lower and higher SES, suggesting that reading fluency growth trajectories for curricula varied depending on student SES and grade level. Findings indicate that while there are similarities among curricula, they sometimes differ in their ability to promote reading skill growth. Differences by grade level and SES were also detected. However, many of these differences were small. Implications for the use of curriculum as a conduit for improving reading instruction are discussed.

    Across the United States, secondary school curricula are intensifying as a growing proportion of students enroll in high-level academic math courses. In many districts, this intensification process occurs as early as eighth grade, where schools are effectively constraining their mathematics curricula by restricting course offerings and placing more students into Algebra I. This paper provides a quantitative single-case research study of policy-driven curricular intensification in one California school district. (1a) What effect did 8th eighth grade curricular intensification have on mathematics course enrollment patterns in Towering Pines Unified schools? (2b) How did the distribution of prior achievement in Towering Pines math classrooms change as the district constrained the curriculum by universalizing 8th eighth grade Algebra? (3c) Did 8th eighth grade curricular intensification improve students' mathematics achievement? Towering Pines is an immigrant enclave in the inner-ring suburbs of a major metropolitan area. The district's 10 middle schools together enroll approximately 4,000 eighth graders each year. The districts' students are ethnically diverse and largely economically disadvantaged. The study draws upon administrative data describing 8th eighth graders in the district in the 2004-20-05 through 2007-20-08 school years. During the study period, Towering Pines dramatically intensified middle school students' math curricula: In the 2004-20-05 school year 32% of the district's 8th eighth graders enrolled in Algebra or a higher- level mathematics course; by the 2007-20-08 school year that proportion had increased to 84%. We use an interrupted time-series design, comparing students' 8th eighth grade math course enrollments, 10th grade math course enrollments, and 10th grade math test scores across the four cohorts, controlling for demographics and prior achievement. We find that students' odds of taking higher level mathematics courses increased as this

    2002-06-01

    This paper describes a model process to increase the exposure of middle and high school students to information on aging so they better understand the implications of an aging population and the stereotypes of older adults. A college Gerontology Institute, a social studies teacher education faculty member, and middle/high school social studies teachers collaborated on a program to develop and implement lesson plans that incorporate information on aging into existing courses. Institute staff provided expertise on gerontology and student teachers assisted in writing lesson plan objectives. Teachers developed about a dozen lessons covering from one class to two weeks in subjects such as global history, participation in government, Western civilizations, economics, and government. This experience suggests a number of issues that should be addressed when developing a gerontology infusion initiative with school teachers. Information on aging can be successfully incorporated into existing school curricula within the constraints of mandated learning objectives.

    To identify the CT features in differentiating grade 3 neuroendocrine carcinomas from grade 1/2 neuroendocrine tumours. This study included 161 patients with surgically confirmed pancreatic neuroendocrine neoplasms. Pathology slides were reviewed to determine the tumour grade. CT image analysis included size, pattern, calcification, margin, pancreatic duct dilatation, bile duct dilatation, vascular invasion, arterial enhancement ratio, and portal enhancement ratio. We used 2 cm, 3 cm, and 4 cm as cutoff values of tumour size and 0.9 and 1.1 of enhancement ratio to determine the sensitivity and specificity. Pathology analysis identified 167 lesions in 161 patients. 154 lesions (92 %) were grade 1/2 and 13 (8 %) were grade 3. Portal enhancement ratio (< 1.1) showed high sensitivity and specificity 92.3 % and 80.5 %, respectively in differentiating grade 3 from grade 1/2. It showed the highest odds ratio (49.60), followed by poorly defined margin, size (> 3 cm), bile duct dilatation, and vascular invasion. When at least two of these five criteria were used in combination, the sensitivity and specificity for diagnosing grade 3 were 92.3 % (12/13) and 87.7 % (135/154), respectively. By using specific CT findings, grade 3 can be differentiated from grade 1/2 with a high diagnostic accuracy leading to an appropriate imaging staging. (orig.)

    Due to the introduction of new degrees on the College of Agricultural Engineering of the Technical University of Madrid adapted to the European Space for Higher Education (Bologna), we have made a comparative study of academic achievement obtained by the students during their first year at the Centre according to different curricula. We used data from 2 curricula leading to the degree in Agricultural Engineering, Curriculumn 74 (6 years and annual structure) and Curriculum 96 modified in 2006 (5 years with quarterly structure) and the new curriculum in grades (4 years semi-structured). It has been used as a data source, the qualifications of new students during the last three years prior to the extinction of the curriculum.The study shows that current rates of academic success or failure and dropout during the first year of college are very similar to those happening 12 years ago, when it was assumed that the preparation of students from high school was much higher than today. Keywords: Academic performance, curricula, Bologna.

    Myrick, Melinda D.

    2007-12-01

    This study examined the extent to which human sexuality topics are covered in Florida middle school science classrooms and the process by which curricular decisions are made regarding human sexuality education on a county-wide basis. Primary data included interviews with county-level administrators who oversee curricular decisions related to the middle-grades science curriculum or health curriculum in twelve school districts within the state. These districts represented four geographic locations and districts of various sizes. Administrators from four of the twelve studies in the sample chose to provide information regarding their human sexuality education curriculum. In two cases, teacher leads were identified and were interviewed to understand the implementation of the curriculum within the classroom. Additional data were collected from the district curriculum guides for human sexuality education and the adopted middle-grades science textbook for each county. The interview and documentary data were analyzed by comparison to established criteria for a comprehensive human sexuality education curriculum. The analysis revealed that the scope of human sexuality education varied considerably within the sample and that much of the curricula in place failed to include topics and activities that have been identified as important in a successful human sexuality education program. These findings are limited because few counties chose to fully participate. Additional research is clearly needed to examine the effectiveness of existing human sexuality education curricula in Florida. In addition, research is needed to understand the characteristics, values, and beliefs of successful human sexuality education instructors across the state.

    2014-07-01

    Understanding the characteristics of experimental smoking among youth is critical for designing prevention programs. This study examined which student- and school-level factors differentiated experimental smokers from never smokers in a nationally representative sample of Canadian students in grades 9 to 12. School-level data from the 2006 Canadian Census and one built environment characteristic (tobacco retailer density) were linked with data from secondary school students from the 2008-2009 Canadian Youth Smoking Survey and examined using multilevel logistic regression analyses. Experimental smoking rates varied across schools (p pocket money each week and had a family member or close friend who smoked cigarettes. School-based tobacco prevention programs need to be grade-sensitive and comprehensive in scope; include strategies that can increase students' attachment to their school; and address multi-substance use, tobacco-related beliefs and the use of pocket money. These programs should also reach out to students who have smoking friends and family members. Schools located in rural settings may require additional resources.

  7. Changing Curriculum: A Critical Inquiry into the Revision of the British Columbia Science Curriculum For Grades K-9

    Science.gov (United States)

    Searchfield, Mary A.

    In 2010 British Columbia's Ministry of Education started the process of redesigning the provincial school curriculum, Kindergarten to Grade 12. Mandatory implementation of the new curriculum was set for the 2016/17 school year for Grades K-9, and 2017/18 for Grades 10-12. With a concerted emphasis on personalized learning and through the frame of a Know-Do-Understand curriculum model, the new curriculum aims to meet the needs of today's learners, described as living in a technology-rich, fast-paced and ever-changing world, through a concept-based and competency-driven emphasis. This thesis is a critical analysis of the BC K-9 Science curriculum as written and published, looking specifically at how science is treated as a form of knowledge, its claimed presentation as a story, and on whether the intentions claimed by the designers are matched in the curriculum's final form.

  9. MMP-9 immunohistochemical expression is correlated with histologic grade in feline diffuse iris melanoma

    Directory of Open Access Journals (Sweden)

    Laura Nordio

    2018-06-01

    Full Text Available Feline diffuse iris melanoma (FDIM is the most common primary intraocular neoplasm in cats. It is usually a malignant tumor, even if slowly progressive, thus representing an unique spontaneous model of the aggressive, although rare, human iris melanoma. In cats, the extent of the tumor within the eye, expressed as histological grade, is considered a good predictor of survival. In the context of the neoplastic cells-tumor microenvironment interaction, Matrix Metalloproteinase-9 (MMP-9 is an endopeptidase able to digest the extracellular matrix with involvement in tumor invasion . MMP-9 expression has been positively correlated with metastasizing behavior in human posterior uveal melanoma. The present study investigates the expression of MMP-9 in a caseload of formalin-fixed paraffin-embedded FDIMs in relation to the histological grade  and mitotic index (MI (threshold=7/10 hpf. Sixty-one samples of FDIM evaluated on light microscopy (Fig. 1 were selected (grade I n=22, grade II n=20, grade III n=19. Immunohistochemical staining with standard ABC method was performed using a mouse anti-MMP-9 antibody. Results were semi-quantitatively scored and compared by Mann-Whitney U test. MMP-9 was expressed in 59,1% grade I FDIM, 90,0% grade II and 80,0% grade III. Tumors with MMP-9 expression in more than 50% of neoplastic cells were 13,6% in grade I cases, 40,0% in grade II and 36,8% in grade III. MMP-9 was expressed in 71,4% of FDIM with MI≤7 and 92,3% of FDIM with MI>7. MMP-9 expression differed significantly between grade I and the other two grades, and between groups with low and high MI. In conclusion, intense expression of MMP-9 seems to correlate with the histological aggressiveness of FDIM.

  10. Explorations of Tenth-Grade STS[E] Curricula across Three Provincial Political Landscapes

    Science.gov (United States)

    Phillips, Christina Ann

    This thesis focuses on explorations of science, technology, society and the environment (i.e., STS[E]) outcomes/expectations in tenth-grade level science curricula across three Canadian provinces (i.e., Alberta, Manitoba & Ontario) with distinctive provincial political environments at the time of curriculum construction and/or implementation. Document analysis, discourse analysis and a range of theoretical frameworks (i.e., Levinson, 2010; Pedretti & Nazir, 2011 & Krathwohl, 2002) were used to aid in explorations of STS[E] curriculum segments and discourses in each provincial region. More detailed analysis and thematic exploration is presented for each unit associated with climate change as some interesting patterns emerged following initial analysis. My findings are presented as three comparative case studies and represent a small and original contribution to the large body of scholarly research devoted to studies of STS[E] education, where each province represents a unique case that has been explored regarding some aspects the STS[E] curriculum outcomes/expectations and general political culture as well as some other theoretical factors. Findings from this study indicate that Alberta's STS[E] outcomes may be related to Levinson's (2010) 'deliberative' citizenship focus. The following currents from Pedretti and Nazir (2011) appear to be emphasized: logical reasoning, historical, application & design and socio-cultural aligned outcomes when STS[E] is considered as an entity separate from the Alberta curriculum combination of STS and Knowledge. Ontario's STS[E] expectations may align with Levinson's (2010) 'deliberative' or in some select cases a 'deliberative'/'praxis' framework category with some emphasis related to logical reasoning and socio-cultural awareness (Pedretti & Nazir, 2011) in their STS[E] curriculum. The Manitoba STS[E] outcomes may be aligned with a more 'deliberative' approach with some associations that could intersect with the framework

  11. The role of morphology and short vowelization in reading Arabic among normal and dyslexic readers in grades 3, 6, 9, and 12.

    Abu-Rabia, Salim

    2007-03-01

    This study was an investigation of several Arabic reading measures among dyslexics and normal Arabic readers across different ages (grades 3, 6, 9, and 12): the role of morphology, short vowelization (phonological and syntactic skills), spelling, reading isolated words, and reading comprehension. The results of the one-way ANOVAs indicated clear differences between the dyslexic readers and the normal readers on all reading measures. However, the stepwise regression analysis revealed consistent orthographic results: morphology (identification and/or production) and spelling were generally the most powerful predictors of both reading accuracy and reading comprehension among dyslexic and normal readers across these different age groups. The results are discussed in terms of the characteristics of the Arabic orthography and the heavy reliance of readers at all levels and ages on orthographic factors in reading.

  13. Teaching with a GIS using existing grade 7--12 curricula

    Science.gov (United States)

    Brown, Stephen Castlebury

    As Geographic Information Systems (GIS) become less expensive and easier to use, the demand for individuals knowledgeable of this technology increases. Associated with this is the current and future necessity of a public who understands the wide range of technical proficiencies needed for accurate GIS mapping. On a nationwide basis, GIS education in K--12 schools is rare. In the few instances where a school teaches students about these technologies, it is usually led by a single teacher and is not taught on a school-wide basis. This situation exists despite some research indicating that a classroom GIS might enhance the learning of students. Two primary barriers to teacher use and acceptance of a classroom GIS have been identified. First, most teachers lack any training in the use of a GIS. Secondly, there is conflict over focusing upon teaching about the use of a GIS or teaching with a GIS. Beginning in August of 1996 and concluding in August of 1998, nine separate GIS education programs were conducted for a variety of youths and adult educator audiences. Observations of participant's interactions with the GIS program ArcView would lead to the development of a demonstration curriculum and GIS application. To overcome institutional and educational barriers to youth GIS education, a curriculum partly adapted from existing materials and partly created from original materials was developed in Hypertext Markup Language (HTML). A corresponding GIS application was developed to teach about a GIS while instructing with a GIS. The curriculum was distributed for use on CD-ROM and called Georom. The hypertext curriculum provided lessons and exercises that addressed National Science Education Standards and was accessed using an Internet web browser. The curriculum included World Wide Web links to Internet sites with more information about specific topics. Modifications were made to ArcView's Graphical User Interface (GUI) that maintained the general appearance of its standard

The same mechanism of Z-phase formation observed in 12%Cr model alloys was identified in industrial 9-12%Cr steels after thousands of hours......The 9-12%Cr ferritic steels are extensively used in modern steam power plants at service temperature up to 620°C. Currently the best perform ing ferritic creep resistance steel is the ASTM Grade 92, whose high temperature strength has recently been assessed by European Creep Collaborative Committee...... in 2005 as 600°C/113MPa/10 5h. All previous attempts made in the last twenty years to develop ferritic steels for 650°C applications have failed due to the incapacity to combine the superior oxidation resistance, given by 12%Cr content, with excellent creep resistance of high-alloyed ferritic steels...

  16. Increasing ocean sciences in K and 1st grade classrooms through ocean sciences curriculum aligned to A Framework for K-12 Science Education, and implementation support.

    Ocean and climate sciences are rarely introduced at the early elementary levels. Reasons for this vary, but include little direct attention at the national and state levels; lack of quality instructional materials; and, lack of teacher content knowledge. Recent recommendations by the National Research Council, "revise the Earth and Space sciences core ideas and grade band endpoints to include more attention to the ocean whenever possible" (NRC, 2012, p. 336) adopted in the Next Generation Science Standards (NGSS), may increase the call for ocean and climate sciences to be addressed. In response to these recommendations' and the recognition that an understanding of some of the Disciplinary Core Ideas (DCIs) would be incomplete without an understanding of processes or phenomena unique to the ocean and ocean organisms; the ocean Literacy community have created documents that show the alignment of NGSS with the Ocean Literacy Principles and Fundamental Concepts (Ocean Literacy, 2013) as well as the Ocean Literacy Scope and Sequence for Grades K-12 (Ocean Literacy, 2010), providing a solid argument for how and to what degree ocean sciences should be part of the curriculum. However, the percentage of science education curricula focused on the ocean remains very low. This session will describe a new project, that draws on the expertise of curriculum developers, ocean literacy advocates, and researchers to meet the challenges of aligning ocean sciences curriculum to NGSS, and supporting its implementation. The desired outcomes of the proposed project are to provide a rigorous standards aligned curricula that addresses all of the Life Sciences, and some Earth and Space Sciences and Engineering Design Core Ideas for Grades K and 1; and provides teachers with the support they need to understand the content and begin implementation. The process and lessons learned will be shared.

    The students' motivation to learn basic sciences in health science curricula is poorly understood. The purpose of this study was to investigate the influence of different components of motivation (intrinsic motivation, self-determination, self-efficacy and extrinsic -career and grade- motivation) on learning human histology in health science curricula and their relationship with the final performance of the students in histology. Glynn Science Motivation Questionnaire II was used to compare students' motivation components to learn histology in 367 first-year male and female undergraduate students enrolled in medical, dentistry and pharmacy degree programs. For intrinsic motivation, career motivation and self-efficacy, the highest values corresponded to medical students, whereas dentistry students showed the highest values for self-determination and grade motivation. Genders differences were found for career motivation in medicine, self-efficacy in dentistry, and intrinsic motivation, self-determination and grade motivation in pharmacy. Career motivation and self-efficacy components correlated with final performance in histology of the students corresponding to the three curricula. Our results show that the overall motivational profile for learning histology differs among medical, dentistry and pharmacy students. This finding is potentially useful to foster their learning process, because if they are metacognitively aware of their motivation they will be better equipped to self-regulate their science-learning behavior in histology. This information could be useful for instructors and education policy makers to enhance curricula not only on the cognitive component of learning but also to integrate students' levels and types of motivation into the processes of planning, delivery and evaluation of medical education.

    This study investigated the effect of grade retention in elementary school on students’ motivation for educational attainment in grade 9. We equated retained and promoted students on 67 covariates assessed in grade 1 through propensity score weighting. Retained students (31.55%, nretained = 177) and continuously promoted students (68.45%, npromoted = 384) were compared on the bifactor model of motivation for educational attainment (Cham, Hughes, West, & Im, 2014). This model consists of a General factor (student’s overall motivation for educational attainment), and three specific factors: student perceived Teacher Educational Expectations, Peer Educational Aspirations, and Value of Education. Measurement invariance between retained and promoted groups was established. Retained students scored significantly higher than promoted students on each specific factor but not on the General factor. Results showed that the retained and promoted students did not significantly differ on the General factor. The retained students had significantly higher scores on each specific factor than the promoted students. The results suggested that grade retention may not have the negative effects so widely assumed in the published literature; it is an expensive intervention with minimal evidence of benefits to the retained student.

    Workforce development strategies to educate, inform, and diversify the veterinary profession of the future must begin with children in elementary school. This article provides a description of the Fat Dogs and Coughing Horses program, which takes a multifaceted approach toward informing young students, beginning in first grade, about the interesting work and career opportunities available in the field of veterinary medicine. The program, a collaboration among Purdue University and Indiana public schools, is supported by a Science Education Partnership Award from the Office of Research Infrastructure Programs, a component of the National Institutes of Health. The overall goal of the program is to provide formal and informal educational opportunities for students, parents, teachers, and the public about the science involved in keeping people and their animals healthy. Examples of health concerns that impact both people and their pets are used to inform and excite children about careers in the health sciences. The program resulted in (1) curricula for students in Grades 1-3, 6, and 9; (2) four children's books and a set of collectible cards which highlight veterinarians, veterinary technicians, and research scientists who work with animals; and (3) four traveling museum-level quality exhibits. Preliminary assessment data has shown that the implementation of the curricula enhanced student science learning and science attitudes and interests. The program provides evidence that partnerships among professionals in veterinary medicine and K-12 education can result in impactful workforce development programs.

    Full Text Available In South Africa, the Grade 12 'classes of 2008 and 2009' were the first to write examinations under the revised Life Sciences (Biology curriculum which focuses on outcomes-based education (OBE. This paper presents an exploration of what students (as learners considered to be difficult and interesting in Grades 10-12 Life Sciences curricula in the Further Education and Training (FET phase. A sample of 125 first year, pre-service Life Sciences and Natural Sciences teachers from a university responded to a questionnaire in regard to their experiences with the newly implemented FET Life Sciences curricula. The responses to the questions were analysed qualitatively and/or quantitatively. Friedman tests were used to compare the mean rankings of the four different content knowledge areas within each curriculum, and to make cross-curricular comparisons of the mean rankings of the same content knowledge area for all three curricula. All four content areas of Grade 12 were considered as being more interesting than the other two grades. In terms of difficulty, the students found the Grade 10 curriculum themes the most difficult, followed by the Grade 12 and the Grade 11 curricula. Most of the students found the themes under the content area Diversity, change and continuity (Grades 10-12 more difficult to learn than the other three content areas. It is recommended that more emphasis needs to be placed on what learners are interested in, and on having this incorporated into Life Sciences curricula.

  13. Current robotic curricula for surgery residents: A need for additional cognitive and psychomotor focus.

    Green, Courtney A; Chern, Hueylan; O'Sullivan, Patricia S

    2018-02-01

    Current robot surgery curricula developed by industry were designed for expert surgeons. We sought to identify the robotic curricula that currently exist in general surgery residencies and describe their components. We identified 12 residency programs with robotic curricula. Using a structured coding form to identify themes including sequence, duration, emphasis and assessment, we generated a descriptive summary. Curricula followed a similar sequence: learners started with online modules and simulation exercises, followed by bedside experience during R2-R3 training years, and then operative opportunities on the console in the final years of training. Consistent portions of the curricula reflect a device-dependent training paradigm; they defined the sequence of instruction. Most curricula lacked specifics on duration and content of training activities. None clearly described cognitive or psychomotor skills needed by residents and none required a proficiency assessment before graduation. Resident-specific robotic curricula remain grounded in initial industrial efforts to train experienced surgeons, are non-specific regarding the type and nature of hands on experience, and do not include discussion of operative technique and surgical concepts.

    Plates, sheets, bars, wires and thinner seam-welded tubings were manufactured from large-scaled ingot of ASTM Grade 12 alloy (Ti-0.8Ni-0.3Mo). The processability of G-12 alloy has proved almost similar to that of conventional commercially pure titanium grades. It has been clarified that the G-12 alloy showed several advantageous features: Chlorides-Crevice corrosion resistance of the alloy was almost equals to G-7 and Pd0/TiO 2 coated titanium, and the maximum allowable stress was able to be designed higher than that of commercially pure titanium. This alloy has been in applications also offers where such environments as seawater, brines and moist chlorine, various oil refinery and chemical industries, and others. (author)

    To evaluate efficacy and safety of 60mg and 120mg Fimasartan (FMS) alone or combined with 12.5mg hydrochlorothiazide (HCTZ) in a Mexican population. A six month, treat-to-target, open study was conducted on subjects with grade 1-2 hypertension. The subjects were initially treated with 60mg FMS once daily. In week 8, those with Diastolic Blood Pressure (DBP) <90mmHg continued on the same FMS dose during the rest of the study, while those with DBP ≥90mmHg were randomised to either 120mg FMS or 60mg FMS + 12.5mg HCTZ once daily. In week 12, randomised subjects with DBP ≥90mmHg received 120mg FMS+12.5mg HCTZ, while those achieving target continued with their assigned treatment until the end of the study. FMS 60mg (n=272) decreased both DBP and Systolic Blood Pressure (SBP) by 11.3±8.9 (p<.0001) and 16.0±14.1 (p<.0001)mmHg, respectively, with 75.4% of subjects reaching the treatment target. Subjects assigned to FMS 120mg, FMS 60mg+HCTZ 12.5mg, or FMS 120mg+HCTZ 12.5mg once daily, showed significant reductions in DBP and SBP with their assigned treatment. At the end of the study, 237/272 subjects (87.1%) achieved a DBP<90mmHg and an SBP<140mmHg. The most frequently reported adverse reactions included headache (3.7%), dry mouth (1.1%), transient liver enzyme increase (1.1%), and dizziness (0.7%).

    2006-03-01

    Most of the spelling error analysis has been conducted in Latin orthographies and rarely conducted in other orthographies like Arabic. Two hundred and eighty-eight students in grades 1-9 participated in the study. They were presented nine lists of words to test their spelling skills. Their spelling errors were analyzed by error categories. The most frequent errors were phonological. The results did not indicate any significant differences in the percentages of phonological errors across grades one to nine.Thus, phonology probably presents the greatest challenge to students developing spelling skills in Arabic.

    Micronutrients are essential to neurocognitive development; yet their role in educational outcomes is unclear. We examined the associations of micronutrient status biomarkers with the risk of grade repetition and rates of school absenteeism in a cohort of school children. We recruited 3156 children aged 5-12 y from public schools in Bogota, Colombia. Circulating ferritin, hemoglobin, zinc, vitamin A, and vitamin B-12; erythrocyte folate; and mean corpuscular volume (MCV) were measured in blood samples obtained at the beginning of the year. Absenteeism was recorded weekly during the school year, and grade repetition was determined the next year. Risk ratios for grade repetition and rate ratios for absenteeism were estimated by categories of micronutrient status indicators with use of Poisson regression, adjusting for potential confounders. The risk of grade repetition was 4.9%, and the absenteeism rate was 3.8 d per child-year of observation.

  4. Cultural competence in medical education: aligning the formal, informal and hidden curricula.

    Science.gov (United States)

    Paul, David; Ewen, Shaun C; Jones, Rhys

    2014-12-01

    The concept of cultural competence has become reified by inclusion as an accreditation standard in the US and Canada, in New Zealand it is demanded through an Act of Parliament, and it pervades discussion in Australian medical education discourse. However, there is evidence that medical graduates feel poorly prepared to deliver cross-cultural care (Weissman et al. in J Am Med Assoc 294(9):1058-1067, 2005) and many commentators have questioned the effectiveness of cultural competence curricula. In this paper we apply Hafferty's taxonomy of curricula, the formal, informal and hidden curriculum (Hafferty in Acad Med 73(4):403-407, 1998), to cultural competence. Using an example across each of these curricular domains, we highlight the need for curricular congruence to support cultural competence development among learners. We argue that much of the focus on cultural competence has been in the realm of formal curricula, with existing informal and hidden curricula which may be at odds with the formal curriculum. The focus of the formal, informal and hidden curriculum, we contend, should be to address disparities in health care outcomes. In conclusion, we suggest that without congruence between formal, informal and hidden curricula, approaches to addressing disparity in health care outcomes in medical education may continue to represent reform without change.

Risk of bias assessed with Cochrane Risk of Bias tool. 50 randomised controlled trials (RCTs) of school-based smoking curricula. Never-smokers age 5-18 (n=143,495); follow-up ≥6 months; all countries; no date/language limitations. Information, social influences, social competence, combined social influences/competence and multimodal curricula. Remaining a never-smoker at follow-up. Pooling all curricula, trials with follow-up ≤1 year showed no statistically significant differences compared with controls (OR 0.91 (0.82 to 1.01)), though trials of combined social competence/social influences curricula had a significant effect on smoking prevention (7 trials, OR 0.59 (95% CI 0.41 to 0.85)). Pooling all trials with longest follow-up showed an overall significant effect in favour of the interventions (OR 0.88 (0.82 to 0.95)), as did the social competence (OR 0.65 (0.43 to 0.96)) and combined social competence/social influences curricula (OR 0.60 (0.43 to 0.83)). No effect for information, social influences or multimodal curricula. Principal findings were not sensitive to inclusion of booster sessions in curricula or to whether they were peer-led or adult-led. Differentiation into tobacco-only or multifocal curricula had a similar effect on the primary findings. Few trials assessed outcomes by gender: there were significant effects for females at both follow-up periods, but not for males. RCTs of baseline never-smokers at longest follow-up found an overall significant effect with average 12% reduction in starting smoking compared with controls, but no effect for all trials pooled at ≤1 year.

    Currently, grade X10CrMoVNb9-1 (T91, P91) and 10Kh9MFB (10Kh9MFB-Sh) chromium steels are widely applied in equipment manufacturing for thermal power plants in Russia and abroad. Compilation and comparison of tensile, impact, and long-term strength tests results accumulated for many years of investigations of foreign grade X10CrMoVNb9-1, T91, P91, and domestic grade 10Kh9MFB (10Kh9MFB-Sh) steels is carried out. The property identity of metals investigated is established. High strength and plastic properties of steels, from which pipes and other products are made, for operation under creep conditions are confirmed. Design characteristics of long-term strength on the basis of tests with more than one million of hour-samples are determined ( and at temperatures of 500-650°C). The table of recommended allowable stresses for grade 10Kh9MFB, 10Kh9MFB-SH, X10CrMoVNb9-1, T91, and P91 steels is developed. The long-time properties of pipe welded joints of grade 10Kh9MFB+10Kh9MFB, 10Kh9MFB-Sh+10Kh9MFB-Sh, X10CrMoVNb9-1+X10CrMoVNb9-1, P91+P91, T91+T91, 10Kh9MFB (10Kh9MFB-Sh)+X10CrMoVNb9-1(T/P91) steels is researched. The welded joint reduction factor is experimentally determined.

    This study describes the prevalence of high-signal changes at magnetic resonance imaging (MRI) of the alar and transverse ligaments in whiplash-associated disorders (WAD) grades 1-2 in relation to age, gender, spinal degeneration, type of trauma event and time since trauma. In 1,266 consecutive WAD1-2 patients (779 women, 487 men; mean age 42 years) referred from clinicians, high-signal changes in the alar and transverse ligaments at high-resolution proton-weighted MRI were prospectively graded 0-3 based on a previously reported, reliable grading system. Type of event according to The International Statistical Classification of Diseases and Related Health Problems and time of trauma were obtained from referral letters. MRI showed grades 2-3 alar ligament changes in 449 (35.5%; 95% confidence interval (CI), 32.8 to 38.1%) and grades 2-3 transverse ligament changes in 311 (24.6%; 95% CI, 22.2% to 26.9%) of the 1,266 patients. Grades 2-3 changes were more common in men than women, odds ratio 1.9 (95% CI, 1.5 to 2.5) for alar and 1.5 (95% CI, 1.1 to 2.0) for transverse ligament changes. High-signal changes were not related to age, spinal degeneration, type of trauma event or time since trauma (median 5 years). Unilateral changes were more often left- than right-sided. High-signal changes of the alar and transverse ligaments are common in WAD1-2 and unlikely to represent age-dependent degeneration. Their male and left-side preponderance cannot be explained by variation in ligament stretching or image artefacts. Further studies are needed to clarify whether such changes are caused by trauma.

    2012-07-01

    The performance of over 5000 students in introductory calculus-based mechanics courses at the Georgia Institute of Technology was assessed using the Force Concept Inventory (FCI). Results from two different curricula were compared: a traditional mechanics curriculum and the Matter & Interactions (M&I) curriculum. Both were taught with similar interactive pedagogy. Post-instruction FCI averages were significantly higher for the traditional curriculum than for the M&I curriculum; the differences between curricula persist after accounting for factors such as pre-instruction FCI scores, grade point averages, and SAT scores. FCI performance on categories of items organized by concepts was also compared; traditional averages were significantly higher in each concept. We examined differences in student preparation between the curricula and found that the relative fraction of homework and lecture topics devoted to FCI force and motion concepts correlated with the observed performance differences. Concept inventories, as instruments for evaluating curricular reforms, are generally limited to the particular choice of content and goals of the instrument. Moreover, concept inventories fail to measure what are perhaps the most interesting aspects of reform: the non-overlapping content and goals that are not present in courses without reform.

    Isothermal tests were performed on commercial 9%Cr and 12%Cr steels between 600 and 750 deg C in air under atmospheric pressure. The same steels were also tested in oxidizing atmosphere enriched with 12% H{sub 2}O at 700 deg C for 24 hours. Kinetics data were registered and the corrosion products were analyzed using different characterization tools such as scanning electron microscope, x-ray diffraction and secondary ions mass spectrometry. 9%Cr steels showed very limited high temperature corrosion behavior in air, because a breakaway appeared after less than 80 hours at 750 deg C. Spinel oxides composed of iron, chromium and manganese (Mn{sub 1.5}Cr{sub 1.5}O{sub 4} and MnFe{sub 2}O{sub 4}) were identified over the surfaces of both steel grades after oxidation. (Cr,Fe){sub 2}O{sub 3} was also identified especially at 700 deg C and 750 deg C, whereas Fe{sub 2}O{sub 3} mainly grew at 600 and 650 deg C. Differences in oxide morphology and composition were noticed between the samples oxidized under air and air + 12 % water vapor. (authors)

    Greene, Anna C.; Giffin, Kristine A.; Greene, Casey S.

    2016-01-01

    Modern technologies are capable of generating enormous amounts of data that measure complex biological systems. Computational biologists and bioinformatics scientists are increasingly being asked to use these data to reveal key systems-level properties. We review the extent to which curricula are changing in the era of big data. We identify key competencies that scientists dealing with big data are expected to possess across fields, and we use this information to propose courses to meet these growing needs. While bioinformatics programs have traditionally trained students in data-intensive science, we identify areas of particular biological, computational and statistical emphasis important for this era that can be incorporated into existing curricula. For each area, we propose a course structured around these topics, which can be adapted in whole or in parts into existing curricula. In summary, specific challenges associated with big data provide an important opportunity to update existing curricula, but we do not foresee a wholesale redesign of bioinformatics training programs.

    Full Text Available Knowledge of the reading strategies used by English Second Language learners can help teachers to plan appropriate lessons and apply relevant methods of teaching reading in order to enhance learners’ reading comprehension. The main objective of this study was to investigate the reading strategies used by Grade 9 English Second Language (ESL learners and also to establish if there was any significant difference between perceived strategy use and gender. The respondents (192 were all ESL learners in Grade 9 in 2011 in a selected school. The study employed a quantitative research method. The study used convenience sampling on a group of 192 Grade 9 learners. The data collected through questionnaires was analysed by means of the Statistical Package for Social Sciences (SPSS software. The findings revealed that the learners did not employ a wide range of reading strategies. The results further indicated that there was no significant difference between boys and girls in terms of strategy use. Based on the above findings several suggestions were made to help teachers improve their teaching and help learners improve their reading comprehension and also about possible areas for future research.

    Maintenance of the interactive Child and Adolescent Trial for Cardiovascular Health (CATCH) third- to fifth-grade curricula was studied in the 56 original intervention schools and 20 of the original control schools 5 years postintervention in four regions of the United States. Target grade teachers completed a self-administered survey that included questions regarding use of the CATCH materials, training in CATCH or other health education, barriers and perceived support for health education, and amount of health education currently taught. Percentage of teachers who continued to teach CATCH in the classroom was low; however, percentages were significantly higher in former intervention compared with control schools, even though control schools received training and materials following the main field trial. The results of this study can provide useful information for future development of classroom health promotion materials with a higher level of sustainability.

  16. Influence of Z-phase on long-term creep stability of martensitic 9-12% Cr steels

    Danielsen, Hilmar K. [Technical Univ. of Denmark, Lyngby (Denmark). Dept. of Mechanical Engineering; Hald, John [DONG Energy A/S (Denmark); Vattenfall (Denmark)

    2010-07-01

    The long-term creep strength of the new generation of martensitic creep resistant 9-12%Cr steels since the well-known steel Grade 91 relies strongly on particle strengthening by fine Mn nitrides based on V and Nb. During long-term high-temperature exposures the Mn nitrides may be replaced by the thermodynamically more stable Z-phases (Cr(V,Nb)N) causing a breakdown in creep strength. Cr contents above 10.5% strongly accelerate Z-phase precipitation, which explains the lack of success for all attempts to develop martensitic creep resistant steels with high Cr content for oxidation protection. However 9%Cr steels do not seem to be affected by the Z-phase. Careful control of the Z-phase precipitation process has led to the design of experimental 12%Cr martensitic steels strengthened by fine Z-phase nitrides based on Nb or Ta. Such steels may again enable the combination of high strength and oxidation resistance in the same alloy. This opens a new pathway for further alloy development of the heat resistant martensitic steels. (orig.)

    2009-03-01

    Student performance in introductory calculus-based electromagnetism (E&M) courses at four large research universities was measured using the Brief Electricity and Magnetism Assessment (BEMA). Two different curricula were used at these universities: a traditional E&M curriculum and the Matter & Interactions (M&I) curriculum. At each university, post-instruction BEMA test averages were significantly higher for the M&I curriculum than for the traditional curriculum. The differences in post-test averages cannot be explained by differences in variables such as pre-instruction BEMA scores, grade point average, or SAT scores.

  16. Influence of national culture on the adoption of integrated medical curricula.

    Science.gov (United States)

    Jippes, Mariëlle; Majoor, Gerard D

    2011-03-01

    Integrated curricula have been implemented in medical schools all over the world. However, among countries different relative numbers of schools with integrated curricula are found. This study aims to explore the possible correlation between the percentage of medical schools with integrated curricula in a country and that country's cultural characteristics. Curricula were defined as not integrated if in the first 2 years of the program at least two out of the three monodisciplinary courses Anatomy, Physiology and Biochemistry were identified. Culture was defined using Hofstede's dimensions Power distance, Uncertainty avoidance, Masculinity/Femininity, and Individualism/Collectivism. Consequently, this study had to be restricted to the 63 countries included in Hofstede's studies which harbored 1,195 medical schools. From each country we randomly sampled a maximum of 15 schools yielding 484 schools to be investigated. In total 91% (446) of the curricula were found. Correlation of percent integrated curricula and each dimension of culture was determined by calculating Spearman's Rho. A high score on the Power distance index and a high score on the Uncertainty avoidance index correlated with a low percent integrated curricula; a high score on the Individualism index correlated with a high percent integrated curricula. The percentage integrated curricula in a country did not correlate with its score on the Masculinity index. National culture is associated with the propensity of medical schools to adopt integrated medical curricula. Consequently, medical schools considering introduction of integrated and problem-based medical curricula should take into account dimensions of national culture which may hinder the innovation process.

    2016-10-10

    Purpose Although medical leadership and management (MLM) is increasingly being recognised as important to improving healthcare outcomes, little is understood about current training of medical students in MLM skills and behaviours in the UK. The paper aims to discuss these issues. Design/methodology/approach This qualitative study used validated structured interviews with expert faculty members from medical schools across the UK to ascertain MLM framework integration, teaching methods employed, evaluation methods and barriers to improvement. Findings Data were collected from 25 of the 33 UK medical schools (76 per cent response rate), with 23/25 reporting that MLM content is included in their curriculum. More medical schools assessed MLM competencies on admission than at any other time of the curriculum. Only 12 schools had evaluated MLM teaching at the time of data collection. The majority of medical schools reported barriers, including overfilled curricula and reluctance of staff to teach. Whilst 88 per cent of schools planned to increase MLM content over the next two years, there was a lack of consensus on proposed teaching content and methods. Research limitations/implications There is widespread inclusion of MLM in UK medical schools' curricula, despite the existence of barriers. This study identified substantial heterogeneity in MLM teaching and assessment methods which does not meet students' desired modes of delivery. Examples of national undergraduate MLM teaching exist worldwide, and lessons can be taken from these. Originality/value This is the first national evaluation of MLM in undergraduate medical school curricula in the UK, highlighting continuing challenges with executing MLM content despite numerous frameworks and international examples of successful execution.

  3. Comparison of student success using "atoms first" versus "traditional" curricula

    Science.gov (United States)

    Hillesheim, Christina S.

    The purpose of this study was to investigate the difference between the "atoms first" and the "traditional" curricula. Specifically focusing on which curriculum better aligns to curricular expectations, leads to higher student success when students are grouped together, and when students are differentiated based on several factors. The main difference between the two approaches being the sequence of topics presented in the first semester general chemistry course. This study involves more than 9,500 general chemistry I and II students over 7 semesters with about half of them being taught using the "atoms first" approach. Student success was measured using the American Chemical Society's (ACS) final examination scores and the final letter grades. Alignment to curricular expectations was determined via a qualitative review of textbooks written for each of the approaches. This showed that the "atoms first" approach better aligns to research supported best practices. An analysis of covariance (ANCOVA) was performed to determine if there is a significant difference between the "atoms first" and the "traditional" curricula. The "traditional" approach was found to lead to higher student achievement for both measures of student success in both chemistry I and II courses. Lastly, multiple linear, multinomial logistic, and binary logistic regressions were run using all of the subgroups---gender, race/ethnicity, major, ACT composite, math ACT, overall GPA, and classroom size---as predictor variables to determine if any significant interactions between the curricular methods and the different subgroups existed. Results found that the relationship between gender, GPA, and classroom size groupings significantly impact student achievement in general chemistry. Specifically, the "traditional" approach lead to higher student success compared to the "atoms first" approach for males, females, below average GPA students, above average GPA students, and students in large classroom

    Kostishyn, V.G.; Panina, L.V.; Timofeev, A.V.; Kozhitov, L.V.; Kovalev, A.N.; Zyuzin, A.K.

    2016-01-01

    Dual ferroic properties of a strong magnetism and large ferroelectricity have been observed in barium BaFe_1_2O_1_9 and strontium SrFe_1_2O_1_9 hexaferrite ceramics. The samples were fabricated by a modified ceramic technique from highly purified raw materials with addition of boron oxide allowing the control of grain size and enhancement of bulk resistivity. Whereas the samples of PbFe_1_2O_1_9 fabricated by the same technological method did not have sufficient electric resistivity to support an electric field and did not exhibit the ferroelectric properties. The structure of the samples examined by X-ray diffraction is consistent with a single hexagonal phase. The grains are randomly oriented with the average grain size of 300–400 nm coated with boron oxide. The magnetic properties are characterised by standard ferrimagnetic behavior with the Neel temperature of about 450 °C. Large spontaneous polarization was observed with the maximal values of 45–50 μC/cm"2 under an applied electric field of 100–300 kV/m. A strong coupling between magnetic and electric ordering was confirmed by measuring the magnetoelectric (ME) parameter and magnetodielectric ratio. These ME characteristics are more advanced than those for well-known room temperature multiferroic BiFeO_3. Furthermore, by applying an electric field, the manipulation of magnetization in the range of up to 9% was observed, which is even greater than in some substituted hexaferrites with a non-collinear magnetic structure. The obtained results on electrical polarization are similar to the values reported for the corresponding hexaferrites sintered by polymer precursor technique. This suggests a promising potential of M-type hexaferrite ceramics in devices utilizing magnetoelectric coupling. - Highlights: • Ba(Sr)Fe_1_2O_1_9-hexaferrites show large room-temperature multiferroic properties. • Small addition of B_2O_3 increases the hexaferrite resistivity by 4 orders of magnitude. • Large spontaneous

    2014-05-15

    The clinical benefit of peptide receptor radionuclide therapy (PRRT) in patients with pancreatic neuroendocrine tumours (pNET) has not yet been well described and defined in its full extent due to limited data in this tumour subgroup. This study was intended to obtain robust, comparative data on the outcome and toxicity of standardized PRRT with {sup 177}Lu-octreotate in a well-characterized population of patients with advanced pNET of grade 1/2 (G1/2). We retrospectively analysed a cohort of 68 pNET patients with inoperable metastatic disease consecutively treated with {sup 177}Lu-octreotate (four intended cycles at 3-monthly intervals; mean activity per cycle 8.0 GBq). Of these 68 patients, 46 (67.6 %) had documented morphological tumour progression during the 12 months before initiation of treatment, and PRRT was the first-line systemic therapy in 35 patients (51.5 %). Response was evaluated according to modified Southwest Oncology Group (SWOG) criteria and additionally with Response Criteria in Solid Tumors (RECIST) 1.1. Survival was analysed using Kaplan-Meier curves and Cox proportional hazards model for univariate and multivariate analyses. Toxicity was assessed by standard follow-up laboratory work-up including blood count, and liver and renal function, supplemented with serial {sup 99m}Tc-DTPA clearance measurements. The median follow-up period was 58 months (range 4 - 112). Reversible haematotoxicity (grade 3 or more) occurred in four patients (5.9 %). No significant nephrotoxicity (grade 3 or more) was observed. Treatment responses (SWOG criteria) consisted of a partial response in 41 patients (60.3 %), a minor response in 8 (11.8 %), stable disease in 9 (13.2 %), and progressive disease in 10 (14.7 %). Median progression-free survival (PFS) and overall survival (OS) were 34 (95 % CI 26 - 42) and 53 months (95 % CI 46 - 60), respectively. A G1 proliferation status was associated with longer PFS (p = 0.04) and OS (p = 0.044) in the multivariate analysis

    Full Text Available The purpose of this study was to investigate the HOX gene expression profile in laryngeal squamous cell carcinoma (LSCC and assess whether some genes are associated with the clinicopathological features and prognosis in LSCC patients. The HOX gene levels were tested by microarray and validated by qRT-PCR in paired cancerous and adjacent noncancerous LSCC tissue samples. The microarray testing data of 39 HOX genes revealed 15 HOX genes that were at least 2-fold upregulated and 2 that were downregulated. After qRT-PCR evaluation, the three most upregulated genes (HOXB9, HOXB13, and HOXD13 were selected for tissue microarray (TMA analysis. The correlations between the HOXB9, HOXB13, and HOXD13 expression levels and both clinicopathological features and prognosis were analyzed. Three HOX gene expression levels were markedly increased in LSCC tissues compared with adjacent noncancerous tissues (P<0.001. HOXB9 was found to correlate with histological grade (P<0.01 and prognosis (P<0.01 in LSCC. In conclusion, this study revealed that HOXB9, HOXB13, and HOXD13 were upregulated and may play important roles in LSCC. Moreover, HOXB9 may serve as a novel marker of poor prognosis and a potential therapeutic target in LSCC patients.

    To investigate whether expression of carbonic anhydrase XII (CA12) is associated with histologic grade of the tumors and radiotherapy outcomes of the patients with invasive cervical cancer. CA12 expression was examined by immunohistochemical stains in cervical cancer tissues from 183 radiotherapy patients. Histological grading was classified as well (WD), moderately (MD) or poorly differentiated (PD). Oligonucleotide microarray experiment was performed using seven cervical cancer samples to examine differentially expressed genes between WD and PD cervical cancers. The association between CA12 and histological grade was analyzed by chi-square test. CA12 and histological grades were analyzed individually and as combined CA12 and histologic grade categories for effects on survival outcome. Immunohistochemical expression of CA12 was highly associated with the histologic grade of cervical cancer. Lack of CA12 expression was associated with PD histology, with an odds ratio of 3.9 (P = 0.01). Microarray analysis showed a fourfold reduction in CA12 gene expression in PD tumors. CA12 expression was marginally associated with superior disease-free survival. Application of the new combined categories resulted in further discrimination of the prognosis of patients with moderate and poorly differentiated tumor grade. Our study indicates that CA12 may be used as a novel prognostic marker in combination with histologic grade of the tumors

    Falkner, Katrina; Vivian, Rebecca

    2015-10-01

    To support teachers to implement Computer Science curricula into classrooms from the very first year of school, teachers, schools and organisations seek quality curriculum resources to support implementation and teacher professional development. Until now, many Computer Science resources and outreach initiatives have targeted K-12 school-age children, with the intention to engage children and increase interest, rather than to formally teach concepts and skills. What is the educational quality of existing Computer Science resources and to what extent are they suitable for classroom learning and teaching? In this paper, an assessment framework is presented to evaluate the quality of online Computer Science resources. Further, a semi-systematic review of available online Computer Science resources was conducted to evaluate resources available for classroom learning and teaching and to identify gaps in resource availability, using the Australian curriculum as a case study analysis. The findings reveal a predominance of quality resources, however, a number of critical gaps were identified. This paper provides recommendations and guidance for the development of new and supplementary resources and future research.

    Danielsen, Hilmar Kjartansson; Hald, John

    2006-01-01

    The literature on the behaviour of modified Z phase Cr(V,Nb)N in creep resistant martensitic 9–12%Cr steels is briefly reviewed. Ten different 9–12%Cr steels were investigated after prolonged exposure at 600–660uC; the modified Z phase was found in all of them. In steels with high Cr content (11......–12%), Z phase precipitates much faster than in 9%Cr steels. Precipitation of Z phase is associated with dissolution of MX carbonitrides, and causes a breakdown in long term creep strength in 9–12%Cr steels. High Cr steels show creep instabilities accompanied with Z phase precipitation, whereas low Cr...... steels show good long term creep stability. A niobium free CrVN variant of the modified Z phase was observed for the first time during the course of this work. The solution temperature of the Cr(V,Nb)N and CrVN modified Z phases was found to be close to 800uC for 11–12%Cr steels, much lower than the 1200...

  13. Searching for scientific literacy and critical pedagogy in socioscientific curricula: A critical discourse analysis

    Science.gov (United States)

    Cummings, Kristina M.

    The omnipresence of science and technology in our society require the development of a critical and scientifically literate citizenry. However, the inclusion of socioscientific issues, which are open-ended controversial issues informed by both science and societal factors such as politics, economics, and ethics, do not guarantee the development of these skills. The purpose of this critical discourse analysis is to identify and analyze the discursive strategies used in intermediate science texts and curricula that address socioscientific topics and the extent to which the discourses are designed to promote or suppress the development of scientific literacy and a critical pedagogy. Three curricula that address the issue of energy and climate change were analyzed using Gee's (2011) building tasks and inquiry tools. The curricula were written by an education organization entitled PreSEES, a corporate-sponsored group called NEED, and a non-profit organization named Oxfam. The analysis found that the PreSEES and Oxfam curricula elevated the significance of climate change and the NEED curriculum deemphasized the issue. The PreSEES and Oxfam curricula promoted the development of scientific literacy while the NEED curricula suppressed its development. The PreSEES and Oxfam curricula both promoted the development of the critical pedagogy; however, only the Oxfam curricula provided authentic opportunities to enact sociopolitical change. The NEED curricula suppressed the development of critical pedagogy. From these findings, the following conclusions were drawn. When socioscientific issues are presented with the development of scientific literacy and critical pedagogy, the curricula allow students to develop fact-based opinions about the issue. However, curricula that address socioscientific issues without the inclusion of these skills minimize the significance of the issue and normalize the hegemonic worldview promoted by the curricula's authors. Based on these findings

    Hald, John

    2004-01-01

    In the recent 25 years creep rupture strength of 9- to 12 %Cr steels for steam pipes and turbines has been doubled by development of new alloys. This development has formed a basis for improved efficiency of fossil fired steam power plants by introduction of advanced steam temperatures...... and pressures. Newly developed steam pipe steels are based on modifications of well-established steels like the X 20CrMoV12 1. Balanced addition of V, Nb and N to a 9Cr 1 Mo steel led to the Modified 9 Cr steel P 91. Addition of 1% W to a 9Cr 1 MoVNbN base composition led to steel E 911 and partial replacement...... of Mo with 1.8 % W combined with a slight amount of Boron led to steel P 92. The creep rupture strength of these new alloys are now secured with long-term tests up to 100,000 hours, which demonstrate improvements of 50% (P 91), 75 % (E 911) and 100 % (P 92) in strength compared to X 20CrMoV12 1....

    Directory of Open Access Journals (Sweden)

    Alex J. Bowers

    2010-05-01

    Full Text Available School personnel currently lack an effective method to pattern and visually interpret disaggregated achievement data collected on students as a means to help inform decision making. This study, through the examination of longitudinal K-12 teacher assigned grading histories for entire cohorts of students from a school district (n=188, demonstrates a novel application of hierarchical cluster analysis and pattern visualization in which all data points collected on every student in a cohort can be patterned, visualized and interpreted to aid in data driven decision making by teachers and administrators. Additionally, as a proof-of-concept study, overall schooling outcomes, such as student dropout or taking a college entrance exam, are identified from the data patterns and compared to past methods of dropout identification as one example of the usefulness of the method. Hierarchical cluster analysis correctly identified over 80% of the students who dropped out using the entire student grade history patterns from either K-12 or K-8.

    Gehlhar, Kirsten; Klimke-Jung, Kathrin; Stosch, Christoph; Fischer, Martin R

    2014-01-01

    As a fundamental element of medical practice, clinical reasoning should be cultivated in courses of study in human medicine. To date, however, no conclusive evidence has been offered as to what forms of teaching and learning are most effective in achieving this goal. The Diagnostic Thinking Inventory (DTI) was developed as a means of measuring knowledge-unrelated components of clinical reasoning. The present pilot study examines the adequacy of this instrument in measuring differences in the clinical reasoning of students in varying stages of education in three curricula of medical studies. The Diagnostic Thinking Inventory (DTI) comprises 41 items in two subscales ("Flexibility in Thinking" and "Structure of Knowledge in Memory"). Each item contains a statement or finding concerning clinical reasoning in the form of a stem under which a 6-point scale presents opposing conclusions. The subjects are asked to assess their clinical thinking within this range. The German-language version of the DTI was completed by 247 student volunteers from three schools and varying clinical semesters. In a quasi-experimental design, 219 subjects from traditional and model courses of study in the German state of North Rhine-Westphalia took part. Specifically, these were 5(th), 6(th) and 8(th) semester students from the model course of study at Witten/Herdecke University (W/HU), from the model (7(th) and 9(th) semester) and traditional (7(th) semester) courses of study at the Ruhr University Bochum (RUB) and from the model course of study (9(th) semester) at the University of Cologne (UoC). The data retrieved were quantitatively assessed. The reliability of the questionnaire in its entirety was good (Cronbach's alpha between 0.71 and 0.83); the reliability of the subscales ranged between 0.49 and 0.75. The different groups were compared using the Mann-Whitney test, revealing significant differences among semester cohorts within a school as well as between students from similar

    Purpose: To test the potential ability of mean diffusivity (MD) and fractional anisotropy (FA) in discriminating between PCa of grade group (GG) 1&2, and GGs ≥ 3. Material and methods: Diffusion Tensor Imaging (DTI) experiments at 3T in a cohort of 38 patients with PCa (fifty lesions in total) were performed, by using different diffusion weights (b values) up to 2500 s/mm 2 . Gleason score (GS) and GG data were correlated with DTI parameters (MD and FA) estimated in PCa. The relation between DTI measures and GS was tested by the linear correlation analysis (Pearson's coefficient). One-way analysis of variance to check the statistical significance of the difference between GG 1&2 and GGs 3, 4, 5, ≥3 was used. Results were reported for each of the three b-values ranges: 0–800 s/mm 2 , 0–1500 s/mm 2 , 0–2500 s/mm 2 . Results: A negative correlation was found between MD and GS. The highest linear correlation was observed when the fit was performed with data acquired in the b-values range 0–2500 s/mm 2 . MD values were significantly different between GG 1&2 and GG = 3 and between GG 1&2 and GG ≥3. Moreover this difference is better defined when high b values (higher than b = 800 s/mm 2 ) are used. The specificity, sensitivity and accuracy in the discrimination between GG 1&2 and GG = 3 were: 90%, 66.7% and 82.4%, respectively when MD was estimated in the b-values range 0–2500 s/mm 2 while these values were 85%, 58.3% and 78.4% when MD was estimated in the b-values range 0–800 s/mm 2 . Conversely FA did not discriminate between GG 1&2 and GG ≥3, at any investigated b-values range. Conclusion: This study suggests that MD estimation in PCa, obtained from DTI acquired at high b-values, can contribute to the diagnosis and grading of prostate cancer while FA is not a useful parameter for this purpose.

    2007-01-01

    Pregraduate medical curricula are currently undergoing a reform process that is moving away from a traditional discipline-related structure and towards problem-based integrated forms of teaching. Imaging sciences, with their inherently technical advances, are specifically influenced by the effects of paradigm shifts in medical education. The teaching of diagnostic radiology should be based on the definition of three core competencies: in vivo visualization of normal and abnormal morphology and function, diagnostic reasoning, and interventional treatment. On the basis of these goals, adequate teaching methods and e-learning tools should be implemented by focusing on case-based teaching. Teaching materials used in the fields of normal anatomy, pathology, and clinical diagnosis may help diagnostic radiology to play a central role in modern pregraduate curricula. (orig.)

By working on the privately owned Island of Lana'i, we had permission for extensive UAS operation. Our initial focus of UAS educational outreach was on coastal ecosystems where erosion of overgrazed lands affects coral reefs and traditional coastal Hawaiian fishpond restoration projects which include high school students. We provide results of our classroom approach allowing students to learn to fly small, inexpensive UAS and discuss the different results at different grade levels. In addition to providing basic concepts of flight aeronautics, we reviewed information on safe and legal operation of UAS, as well as data management issues including geo-registration and imaging mosaics. We recommend science projects where UAS can study short-term events (e.g. storm runoff) or can be used for routine environmental monitoring over longer periods. Additionally, by linking students with local drone and drone racing clubs student participation and interest in UAS was extended beyond the classroom in a complementary manner. We propose inclusion of UAS into a future high school curriculum via a program called the Moonshot Laboratory which strives to repurpose traditional education structures toward design thinking, making use of individual and group collaborations to address self-selected projects relevant to local community interests. A Moonshot facility allows students to spend a portion of their week in a technology equipped makerspace, with access to university, business and community mentors, both local and remote. UAS projects are expected to address basic student questions, such as: how can I build a drone to take water samples?; how can I

    Full Text Available This study investigated the opportunity to learn (OTL that is available to Grade 12 mathematics learners. Learner workbooks were analysed in terms of time on task, curriculum coverage, curriculum coherence, and cognitive demand. Based on these elements, experienced mathematics teachers judged the opportunity that the learners have to achieve more than 60% for each topic. According to the workbooks, the average number of active learning days in this sample was 54.1 days per annum. This resulted in limited curriculum coverage in almost all sections in 16 of the 18 under-performing schools. In these schools, learners spent most of their time practising routine procedures. The high correlation of 0.95 (p < 0.001 between the experts'prediction about the opportunity to learn in the different schools (based on the learner workbooks and learners' actual performance in the Grade 12 exam shows that the number, the coverage, the cognitive level, and the coherence of activities play a major role in understanding learner performance.

    2017-10-26

    The demand for highly qualified and skilled nurses is increasing in South Africa as well as around the world. Having a background in science can create a significant advantage for students wishing to enrol for an undergraduate nursing qualification because nursing as profession is grounded in scientific evidence. The aim of this study was to investigate the predictive validity of grade 12 mathematics and science on the academic performance of first year student nurses in science modules. A quantitative research method using a cross-sectional predictive design was employed in this study. The participants included first year Bachelor of Nursing students enrolled at a university in the Western Cape, South Africa. Descriptive and inferential statistics were performed to analyse the data by using the IBM Statistical Package for Social Sciences versions 24. Descriptive analysis of all variables was performed as well as the Spearman's rank correlation test to describe the relationship among the study variables. Standard multiple linear regressions analysis was performed to determine the predictive validity of grade 12 mathematics and science on the academic performance of first year student nurses in science modules. The results of this study showed that grade 12 physical science is not a significant predictor (p > 0.062) of performance in first year science modules. The multiple linear regression revealed that grade 12 mathematics and life science grades explained 37.1% to 38.1% (R2 = 0.381 and adj R2 = 0.371) of the variation in the first year science grade distributions. Based on the results of the study it is evident that performance in grade 12 mathematics (β = 2.997) and life science (β = 3.175) subjects is a significant predictor (p < 0.001) of the performance in first year science modules for student nurses at the university identified for this study.

  6. Influence of Z-phase on long-term creep stability of martensitic 9-12%Cr steels

    Energy Technology Data Exchange (ETDEWEB)

    Hald, J. [DONG Energy (Denmark)]|[Vattenfall Europe AG, Berlin (Germany)]|[DTU Mechanical Engineering (Denmark); Danielsen, H.K. [DTU Mechanical Engineering (Denmark)

    2008-07-01

    The long-term creep strength of the new generation of martensitic creep resistant 9- 12% Cr steels since the well-known steel Grade 91 relies strongly on particle strengthening by fine MN nitrides based on V and Nb. During long-term hightemperature exposures the MN nitrides may be replaced by the thermodynamically more stable Z-phases (Cr(V,Nb)N) causing a breakdown in creep strength. Cr contents above 10.5% strongly accelerate Z-phase precipitation, which explains the lack of success for all attempts to develop martensitic creep resistant steels with high Cr content for oxidation protection. The Z-phase nucleation process by Cr-diffusion into pre-existing MN nitrides is rate controlling for the Z-phase transformation. More work is needed before effects of chemical composition on the nucleation process can be reliably modeled. Careful control of the Z-phase precipitation process has led to the design of experimental 12%Cr martensitic steels strengthened by Z-phase. Such steels may again enable the combination of high strength and oxidation resistance in the same alloy. This opens a new pathway for further alloy development of the heat resistant martensitic steels. (orig.)

    Anastomotic leak is a devastating postoperative complication following rectal anastomoses associated with significant clinical and oncological implications. As a result, there is a need for novel intraoperative methods that will help predict anastomotic leak. From 2011 to 2014, patient undergoing rectal anastomoses by colorectal surgeons at our institution underwent prospective application of intraoperative flexible endoscopy with mucosal grading. Retrospective review of patient medical records was performed. After creation of the colorectal anastomosis, application of a three-tier endoscopic mucosal grading system occurred. Grade 1 was defined as circumferentially normal appearing peri-anastomotic mucosa. Grade 2 was defined as ischemia or congestion involving 30% of the colon or rectal mucosa or ischemia/congestion involving both sides of the staple line. From 2011 to 2014, a total of 106 patients were reviewed. Grade 1 anastomoses were created in 92 (86.7%) patients and Grade 2 anastomoses were created in 10 (9.4%) patients. All 4 (3.8%) Grade 3 patients underwent immediate intraoperative anastomosis takedown and re-creation, with subsequent re-classification as Grade 1. Demographic and comorbidity data were similar between Grade 1 and Grade 2 patients. Anastomotic leak rate for the entire cohort was 12.2%. Grade 1 patients demonstrated a leak rate of 9.4% (9/96) and Grade 2 patients demonstrated a leak rate of 40% (4/10). Multivariate logistic regression associated Grade 2 classification with an increased risk of anastomotic leak (OR 4.09, 95% CI 1.21-13.63, P = 0.023). Endoscopic mucosal grading is a feasible intraoperative technique that has a role following creation of a rectal anastomosis. Identification of a Grade 2 or Grade 3 anastomosis should provoke strong consideration for immediate intraoperative revision.

    2017-08-01

    Simulated learning experiences are increasingly being used in health-care education to enhance student engagement and provide experiences that reflect clinical practice; however, simulation has not been widely investigated in occupational therapy curricula. The aim of this paper was to: (i) describe the existing research about the use and evaluation of simulation over the last three decades in occupational therapy curricula and (ii) consider how simulation has been used to develop competence in students. A literature review was undertaken with searches of MEDLINE, CINAHL and ERIC to locate articles that described or evaluated the use of simulation in occupational therapy curricula. Fifty-seven papers were identified. Occupational therapy educators have used the full scope of simulation modalities, including written case studies (22), standardised patients (13), video case studies (15), computer-based and virtual reality cases (7), role-play (8) and mannequins and part-task trainers (4). Ten studies used combinations of these modalities and two papers compared modalities. Most papers described the use of simulation for foundational courses, as for preparation for fieldwork, and to address competencies necessary for newly graduating therapists. The majority of studies were descriptive, used pre-post design, or were student's perceptions of the value of simulation. Simulation-based education has been used for a wide range of purposes in occupational therapy curricula and appears to be well received. Randomised controlled trials are needed to more accurately understand the effects of simulation not just for occupational therapy students but for longer term outcomes in clinical practice. © 2017 Occupational Therapy Australia.

    The purpose of the current study was to investigate the effectiveness of interacting with animations using mobile devices on grade 12 students' spatial and reasoning abilities. The study took place in a grade 12 context in Oman. A quasi-experimental design was used with an experimental group of 32 students and a control group of 28 students. The experimental group studied chemistry using mobile tablets that had a digital instructional package with different animation and simulations. There was one tablet per student. A spatial ability test and a scientific reasoning test were administered to both groups prior and after the study, which lasted for 9 weeks. The findings showed that there were significant statistical differences between the two groups in terms of spatial ability in favour of the experimental group. However, there were no differences between the two groups in terms of reasoning ability. The authors reasoned that the types of animations and simulations used in the current study featured a wide range of three-dimensional animated illustrations at the particulate level of matter. Most probably, this decreased the level of abstractness that usually accompanies chemical entities and phenomena and helped the students to visualize the interactions between submicroscopic entities spatially. Further research is needed to decide on types of scientific animations that could help students improve their scientific reasoning.

    To examine the integration of disability-content in a national sample of nurse practitioner curricula. Responses of National Organization of Nurse Practitioner Faculties (NONPF) members to an online 34-item survey designed to assess disability-related content included in nurse practitioner (NP) curricula; populations of people with disabilities addressed; models of disability; and resources used to teach about disability, facilitators and barriers to inclusion of disability, and respondents' assessment of the adequacy of coverage of disability in their programs. A survey used previously to assess integration of disability content in undergraduate nursing programs was modified to make it relevant to NP curricula. Nursing faculty and people with disability validated the survey to ensure its completeness and sensitivity to the disability community. Participating programs represent 111 (33.6%) NP programs. Lack of disability-related content reported by NP faculty in the majority of programs suggests that there is considerable room for improvement in efforts to address this often vulnerable population. Because people with disabilities can be found in any setting where health care is provided, all NPs need to be prepared to care for people with disabilities across the life span. Strategies need to be developed and implemented to increase the awareness of NP faculty about the health issues of people with disabilities and integration of disability-related content without disrupting existing overloaded NP curricula. © 2014 American Association of Nurse Practitioners.

    2017-03-01

    The ability of health professionals to collaborate effectively has significant potential impact on patient safety and quality-care outcomes, especially given the increasingly complex and dynamic clinical practice environments of today. Educators of the health professions are faced with an immediate challenge to adapt curricula and traditional teaching methods to ensure graduates are equipped with the necessary interprofessional competencies and (inter)professional values for their future practice. The World Health Organization's "Framework for action in interprofessional education (IPE) and collaborative practice" promotes IPE as a key strategy to enhance patient outcomes by preparing a "collaborative practice-ready health workforce." Logistical and attitudinal barriers can hinder integration of IPE into curricula. Lessons learned through the implementation of a planned change to establish four interprofessional seminars (team communication, medical error communication, healthcare English, and small business management) at Heidelberg University Medical Faculty, Germany, are described. A key factor in successfully anchoring IPE seminars in the undergraduate curricula was the structured approach drawing on change management concepts.

    The analyzing power Asub(#betta#)(theta) for 12 C(n,n) 12 C elastic scattering and for inelastic scattering to the first excited state (Jsup(π) = 2 + , Q = -4.44 MeV) of 12 C was measured in the energy range from 8.9 to 14.9 MeV in 1 MeV steps. A pulsed polarized neutron beam was produced via the 2 H(d vector,n vector) 3 He polarization transfer reaction. Monte Carlo simulations were used to correct the data for finite geometry and multiple scattering effects. The Asub(#betta#) data, together with publsihed cross-section data, were analyzed in the framework of the spherical optical model and in the coupled-channels formalism. A good description of the data has been achieved. (orig.)

    England, A.; Azevedo, K.B.; Bezzina, P.; Henner, A.; McNulty, J.P.

    2016-01-01

    Purpose: To establish an understanding of patient safety within radiography education across Europe by surveying higher education institutions registered as affiliate members of the European Federation of Radiographer Societies (EFRS). Method: An online survey was developed to ascertain data on: programme type, patient safety definitions, relevant safety topics, specific areas taught, teaching and assessment methods, levels of teaching and curriculum drivers. Responses were identifiable in terms of educational institution and country. All 54 affiliated educational institutions were invited to participate. Descriptive and thematic analyses are reported. Results: A response rate of 61.1% (n = 33) was achieved from educational institutions representing 19 countries. Patient safety topics appear to be extremely well covered across curricula, however, topics including radiation protection and optimisation were not reported as being taught at an ‘advanced level’ by five and twelve respondents, respectively. Respondents identified the clinical department as the location of most patient safety-related teaching. Conclusions: Patient safety topics are deeply embedded within radiography curricula across Europe. Variations exist in terms of individual safety topics including, teaching and assessment methods, and the depth in which subjects are taught. Results from this study provide a baseline for assessing developments in curricula and can also serve as a benchmark for comparisons. - Highlights: • First European report on patient safety (PS). • PS deeply embedded within training curricula. • Terms and definitions largely consistent. • Some variety in the delivery and assessment methods. • Report provides baseline and opportunities for comparisons.

    1992-04-01

    Differential cross sections of the 9 Be(α,n) 12 C reaction have been measured at 19 alpha energies between 7 MeV and 16 MeV. Besides the differential cross sections from the 9 Be(α,n) 12 C(g.s.) reaction, also those of the 9 Be(α,n) 12 C(E ex ) reactions were derived for excitation energies E ex = 4.439, 7.654, 9.641, 10.84, 11.83 and 12.71 MeV. Possible sources of uncertainties have been extensively investigated and the corresponding results have been published in part 1. All partial and integrated cross sections from the 9 Be(α,n) 12 C(g.s.) reaction were determined with uncertainties of less than 5%. The angular distributions were fitted to Legendre polynomial expansions by the least-squares method. A comparison of the measured cross sections with data from other authors and with an evaluation shows considerable deviations in some cases. Tests were also carried out to ascertain how well an interpolation of the Legendre coefficients reproduces the magnitude and shape of the experimentally determined angular distributions. All angular distributions are presented in figures, together with their Legendre polynomial expansions and data from the literature if available. The a l coefficients of the Legendre polynomial expansions are given in the Appendix. (orig.) [de

    The present article compares the cyclic behaviour of various 9-12%Cr steels, both commercial grades and optimized materials (in terms of creep strength). These materials were subjected to high temperature fatigue and creep-fatigue loadings. TEM examinations of the microstructure after cyclic loadings were also carried out. It appears that all the tempered ferritic-martensitic steels suffer from a cyclic softening effect linked to the coarsening of the sub-grains and laths and to the decrease of the dislocation density. These changes of the microstructure lead to a drastic loss in creep strength for all the materials under study. However, due to a better precipitation state, several materials optimized for their creep strength still present a good creep resistance after cyclic softening. These results are discussed and compared to the literature in terms of the physical mechanisms responsible for cyclic and creep deformation at the microstructural scale. (authors)

    Full Text Available Financial and internal auditors must cope with the challenge of performing their mission in technology enhanced environment. In this article we match the information technology description found in the International Federation of Accountants (IFAC and the Institute of Internal Auditors (IIA curricula against the Model Curriculum issued by the Information Systems Audit and Control Association (ISACA. By reviewing these three curricula, we matched the content in the ISACA Model Curriculum with the IFAC International Education Practice Statement 2 and the IIAs’ Global Model Internal Audit Curriculum. In the IFAC and IIA Curriculum there are 16 content elements, out of 19 possible, which match, in their description, the ISACA Model Curriculum’s content. We noticed that a candidate who graduates an IFAC or IIA compliant program acquire IS auditing competences similar to the specific content of the ISACA model curriculum but less than the requirements for a professional information systems auditor.

    Paterson, Audrey

    2012-01-01

    The aim of this paper is to discuss pre-registration radiography education curricula in the context of cancer, changing healthcare delivery in the UK, and the considerable interaction of radiographers with people with cancer. The fitness for purpose of the long-standing curriculum model of alternating academic and clinical learning experiences is questioned and a view expressed that it is no longer sufficient to prepare student radiographers for practice and as professionals. A suggestion is made that curricula should be aligned with cancer (and other) care pathways although it is recognised that such a change would be difficult. It is concluded that the profession should explore what is the appropriate curriculum model given the development of the care pathway approach to healthcare delivery, and, if appropriate, make changes based on research evidence.

    2013-01-01

    Full Text Available Interleukin-(IL- 12 has been recently suggested to participate during development of insulin resistance in obese mice. Nevertheless, serum IL-12 levels have not been accurately determined in overweight and obese humans. We thus studied serum concentrations of IL-12 in Mexican adult individuals, examining their relationship with low-grade inflammation and obesity-related parameters. A total of 147 healthy individuals, 43 normal weight, 61 overweight, and 43 obese subjects participated in the study. Circulating levels of IL-12, tumor necrosis factor-alpha (TNF-α, leptin, insulin, glucose, total cholesterol, and triglyceride were measured after overnight fasting in all of the study subjects. Waist circumference and body fat percentage were recorded for all the participants. Serum IL-12 was significantly higher in overweight and obese individuals than in normal weight controls. Besides being strongly related with body mass index (r=0.5154, serum IL-12 exhibited a significant relationship with abdominal obesity (r=0.4481, body fat percentage (r=0.5625, serum glucose (r=0.3158, triglyceride (r=0.3714, and TNF-α (r=0.4717. Thus, serum levels of IL-12 are increased in overweight and obese individuals and show a strong relationship with markers of low-grade inflammation and obesity in the Mexican adult population. Further research is needed to understand the role of IL-12 in developing obesity-associated alterations in humans.

    2018-01-01

    Adopting evidence-based practice (EBP) principles in undergraduate education can facilitate nursing students' appreciation of EBP. Using grounded theory method, this study aimed to explore processes used by nurse academics while integrating EBP concepts in undergraduate nursing curricula across Australian universities. Twenty-three nurse academics were interviewed and nine were observed during teaching of undergraduate students. In addition, 20 unit/subject guides were analyzed using grounded theory approach of data analysis. The theory " On a path to success: Endeavoring to contextualize curricula within an EBP framework" reflects academics' endeavors toward linking EBP concepts to practice, aiming to contextualize curricula in a manner that engages students within an EBP framework. However, academics' journeys were influenced by several contextual factors which require strategies to accomplish their endeavors. In conclusion, initiatives to minimize barriers, faculty development, and provision of resources across educational and clinical settings are fundamental to achieving undergraduate curricula underpinned by EBP concepts.

    Okamoto, Carol Midori

    2006-04-01

    This study explored how individuals (biomedical scientists, Great Ape Project activists, lay adults, undergraduate biology and environmental studies students, and Grade 12 and 9 biology students) morally judge and reason about using great apes in biomedical and language research. How these groups perceived great apes' mental capacities (e.g., pain, logical thinking) and how these perceptions related to their judgments were investigated through two scenarios. In addition, the kinds of informational statements (e.g., biology, economics) that may affect individuals' scenario judgments were investigated. A negative correlation was found between mental attributions and scenario judgments while no clear pattern occurred for the informational statements. For the biomedical scenario, all groups significantly differed in mean judgment ratings except for the biomedical scientists, GAP activists and Grade 9 students. For the language scenario, all groups differed except for the GAP activists, and undergraduate environmental studies and Grade 9 students. An in-depth qualitative analysis showed that although the biomedical scientists, GAP activists and Grade 9 students had similar judgments, they produced different mean percentages of justifications under four moral frameworks (virtue, utilitarianism, deontology, and welfare). The GAP activists used more virtue reasoning while the biomedical scientists and Grade 9 students used more utilitarian and welfare reasoning, respectively. The results are discussed in terms of developing environmental/humane education curricula.

  10. Integrating the New Generation Science Standards (NGSS) into K- 6 teacher training and curricula

    Science.gov (United States)

    Pinter, S.; Carlson, S. J.

    2017-12-01

    The Next Generation Science Standards is an initiative, adopted by 26 states, to set national education standards that are "rich in content and practice, arranged in a coherent manner across disciplines and grades to provide all students an internationally benchmarked science education." Educators now must integrate these standards into existing curricula. Many grade-school (K-6) teachers face a particularly daunting task, as they were traditionally not required to teach science or only at a rudimentary level. The majority of K-6 teachers enter teaching from non-science disciplines, making this transition even more difficult. Since the NGSS emphasizes integrated and coherent progression of knowledge from grade to grade, prospective K-6 teachers must be able to deliver science with confidence and enthusiasm to their students. CalTeach/MAST (Mathematics and Science Teaching Program) at the University of California Davis, has created a two-quarter sequence of integrated science courses for undergraduate students majoring in non-STEM disciplines and intending to pursue multiple-subject K-6 credentials. The UCD integrated science course provides future primary school teachers with a basic, but comprehensive background in the physical and earth/space sciences. Key tools are taught for improving teaching methods, investigating complex science ideas, and solving problems relevant to students' life experiences that require scientific or technological knowledge. This approach allows prospective K-6 teachers to explore more effectively the connections between the disciplinary core ideas, crosscutting concepts, and scientific and engineering practices, as outlined in the NGSS. In addition, they develop a core set of science teaching skills based on inquiry activities and guided lab discussions. With this course, we deliver a solid science background to prospective K-6 teachers and facilitate their ability to teach science following the standards as articulated in the NGSS.

  11. Nursing philosophy: A review of current pre registration curricula in the UK.

    Science.gov (United States)

    Mackintosh-Franklin, Carolyn

    2016-02-01

    Nursing in the UK has been subject to criticism for failing to provide care and compassion in practice, with a series of reports highlighting inadequacies in care. This scrutiny provides nursing with an ideal opportunity to evaluate the underpinning philosophy of nursing practice, and for nurse educators to use this philosophy as the basis for programmes which can inculcate neophyte student nurses with a fundamental understanding of the profession, whilst providing other health care professionals and service users with a clear representation of professional nursing practice. The key word philosophy was used in a systematic stepwise descriptive content analysis of the programme specifications of 33 current undergraduate programme documents, leading to an undergraduate award and professional registration as a nurse. The word philosophy featured minimally in programme specification documents, with 12 (36%) documents including it. Its use was superficial in 3 documents and focused on educational philosophy in a further 3 documents. 2 programme specifications identified their philosophy as the NMC (2010) standards for pre-registration nurse education. 2 programme specifications articulated a philosophy specific to that programme and HEI, focusing on caring, and 2 made reference to underpinning philosophies present in nursing literature; the Relationship Centred Care Approach, and The Humanising Care Philosophy. The philosophy of nursing practice is not clearly articulated in pre-registration curricula. This failure to identify the fundamental nature of nursing is detrimental to the development of the profession, and given this lack of direction it is not surprising that some commentators feel nursing has lost its way. Nurse educators must review their current curricula to ensure that there is clear articulation of nursing's professional philosophical stance, and use this as the framework for pre-registration curricula to support the development of neophyte nursing

    to assess the level, type and content of pre-service education curricula of health workers providing maternity services against the ICM global standards for Midwifery Education and Essential competencies for midwifery practice. We reviewed the quality and relevance of pre-service education curricula of four cadres of health-care providers of maternity care in Northern Nigeria. we adapted and used the ICM global standards for Midwifery Education and Essential competencies for midwifery practice to design a framework of criteria against which we assessed curricula for pre-service training. We reviewed the pre-service curricula for Nurses, Midwives, Community Health Extension Workers (CHEW) and Junior Community Health Extension Workers (JCHEW) in three states. Criteria against which the curricula were evaluated include: minimum entry requirement, the length of the programme, theory: practice ratio, curriculum model, minimum number of births conducted during training, clinical experience, competencies, maximum number of students allowable and proportion of Maternal, Newborn and Child Health components (MNCH) as part of the total curriculum. four pre-service education programmes were reviewed; the 3 year basic midwifery, 3 year basic nursing, 3 year Community Health Extension Worker (CHEW) and 2 year Junior Community Health Extension Worker (JCHEW) programme. Findings showed that, none of these four training curricula met all the standards. The basic midwifery curriculum most closely met the standards and competencies set out. The nursing curriculum showed a strong focus on foundations of nursing practice, theories of nursing, public health and maternal newborn and child health. This includes well-defined modules on family health which are undertaken from the first year to the third year of the programme. The CHEW and JCHEW curricula are currently inadequate with regard to training health-care workers to be skilled birth attendants. although the midwifery curriculum

    2012-01-01

    There has been limited identification of core lesbian, gay, bisexual, transgendered, or intersexed (LGBTI) experience concepts that should be included in the nursing curricula. This article addresses the gap in the literature. To move nursing toward the goals of health equity and cultural humility in practice, education, and research, nursing curricula must integrate core LGBTI concepts, experiences, and needs related to health and illness. This article reviews LGBTI health care literature to address the attitudes, knowledge, and skills needed to address curricular gaps and provide content suggestions for inclusion in nursing curricula. Also considered is the need to expand nursing students' definition of diversity before discussing the interplay between nurses' attitudes and culturally competent care provided to persons who are LGBTI. Knowledge needed includes a life span perspective that addresses developmental needs and their impact on health concerns throughout the life course; health promotion and disease prevention with an articulation of unique health issues for this population; mental health concerns; specific health needs of transgender and intersex individuals; barriers to health care; interventions and resources including Internet sites; and legal and policy issues. Particular assessment and communication skills for LGBTI patients are identified. Finally, there is a discussion of didactic, simulation, and clinical strategies for incorporating this content into nursing curricula at the undergraduate and graduate levels.

    Surgical conditions are an important component of global disease burden, due in part to critical shortages of adequately trained surgical providers in low- and middle-income countries. To assess the use of Internet-based educational platforms as a feasible approach to augmenting the education and training of surgical providers in these settings. Access to two online curricula was offered to 75 surgical faculty and trainees from 12 low- and middle-income countries for 60 days. The Surgical Council on Resident Education web portal was designed for general surgery trainees in the United States, and the School for Surgeons website was built by the Royal College of Surgeons in Ireland specifically for the College of Surgeons of East, Central and Southern Africa. Participants completed an anonymous online survey detailing their experiences with both platforms. Voluntary respondents were daily Internet users and endorsed frequent use of both print and online textbooks as references. Likert scale survey questionnaire responses indicating overall and content-specific experiences with the Surgical Council on Resident Education and School for Surgeons curricula. Survey responses were received from 27 participants. Both online curricula were rated favorably, with no statistically significant differences in stated willingness to use and recommend either platform to colleagues. Despite regional variations in practice context, there were few perceived hurdles to future curriculum adoption. Both the Surgical Council on Resident Education and School for Surgeons educational curricula were well received by respondents in low- and middle-income countries. Although one was designed for US surgical postgraduates and the other for sub-Saharan African surgical providers, there were no significant differences detected in participant responses between the two platforms. Online educational resources have promise as an effective means to enhance the education of surgical providers in low

    There is an evident misbalance in the frequency of medical schools with problem-based learning (PBL) curricula in northern versus southern Europe. This study explores the hypothesis that national culture influences the flexibility of (medical) schools in terms of their propensity to adopt integrated and PBL curricula. National culture was defined by a country's scores on indexes for 4 dimensions of culture as described by Hofstede, defined as: power distance; individualism/collectivism; masculinity/femininity, and uncertainty avoidance. Non-integrated medical curricula were defined as those that included courses in 2 of the 3 basic sciences (anatomy, biochemistry and physiology) in the first 2 years; otherwise, by exclusion, curricula were assumed to be integrated. The medical curricula of 134 of the 263 schools in the 17 European countries included in Hofstede's study were examined. Correlations were calculated between the percentage of integrated medical curricula in a country and that country's scores on indexes for each of the 4 dimensions of culture. Significant negative correlations were found between the percentage of integrated curricula and scores on the power distance index (correlation coefficient [CC]: - 0.692; P = 0.002) and the uncertainty avoidance index (CC: - 0.704; P = 0.002). No significant correlations were found between the percentage of integrated curricula and scores on the indexes for individualism/collectivism and masculinity/femininity. A (medical) school which is considering adopting an integrated or PBL curriculum and which is based in a country with a high score on Hofstede's power distance index and/or uncertainty avoidance index must a priori design strategies to reduce or overcome the obstructive effects of these dimensions of culture on the school's organisation.

  6. STEM development: A study of 6th--12th grade girls' interest and confidence in mathematics and science

    Science.gov (United States)

    Heaverlo, Carol Ann

    Researchers, policymakers, business, and industry have indicated that the United States will experience a shortage of professionals in the Science, Technology, Engineering, and Mathematics (STEM) fields. Several strategies have been suggested to address this shortage, one of which includes increasing the representation of girls and women in the STEM fields. In order to increase the representation of women in the STEM fields, it is important to understand the developmental factors that impact girls' interest and confidence in STEM academics and extracurricular programs. Research indicates that greater confidence leads to greater interest and vice versa (Denissen et al., 2007). This study identifies factors that impact girls' interest and confidence in mathematics and science, defined as girls' STEM development. Using Bronfenbrenner's (2005) bioecological model of human development, several factors were hypothesized as having an impact on girls' STEM development; specifically, the macrosystems of region of residence and race/ethnicity, and the microsystems of extracurricular STEM activities, family STEM influence, and math/science teacher influence. Hierarchical regression analysis results indicated that extracurricular STEM involvement and math teacher influence were statistically significant predictors for 6--12th grade girls' interest and confidence in mathematics. Furthermore, hierarchical regression analysis results indicated that the only significant predictor for 6--12th grade girls' interest and confidence in science was science teacher influence. This study provides new knowledge about the factors that impact girls' STEM development. Results can be used to inform and guide educators, administrators, and policy makers in developing programs and policy that support and encourage the STEM development of 6--12th grade girls.

    Robotic surgery is a rapidly expanding field. Thus far training for robotic techniques has been unstructured and the requirements are variable across various regions. Several projects are currently underway to develop a robotic surgery curriculum and are in various stages of validation. We aimed to outline the structures of available curricula, their process of development, validation status and current utilization. We undertook a literature review of papers including the MeSH terms "Robotics" and "Education". When we had an overview of curricula in development, we searched recent conference abstracts to gain up to date information. The main curricula are the FRS, the FSRS, the Canadian BSTC and the ERUS initiative. They are in various stages of validation and offer a mixture of theoretical and practical training, using both physical and simulated models. Whilst the FSRS is based on tasks on the RoSS virtual reality simulator, FRS and BSTC are designed for use on simulators and the robot itself. The ERUS curricula benefits from a combination of dry lab, wet lab and virtual reality components, which may allow skills to be more transferable to the OR as tasks are completed in several formats. Finally, the ERUS curricula includes the OR modular training programme as table assistant and console surgeon. Curricula are a crucial step in global standardisation of training and certification of surgeons for robotic surgical procedures. Many curricula are in early stages of development and more work is needed in development and validation of these programmes before training can be standardised.

    2012-01-01

    Introduction: In 2007 ESTRO proposed a revision and harmonisation of the core curricula for radiation oncologists, medical physicists and RTTs to encourage harmonised education programmes for the professional disciplines, to facilitate mobility between EU member states, to reflect the rapid development of the professions and to secure the best evidence-based education across Europe. Material and methods: Working parties for each core curriculum were established and included a broad representation with geographic spread and different experience with education from the ESTRO Educational Committee, local representatives appointed by the National Societies and support from ESTRO staff. Results: The revised curricula have been presented for the ESTRO community and endorsement is ongoing. All three curricula have been changed to competency based education and training, teaching methodology and assessment and include the recent introduction of the new dose planning and delivery techniques and the integration of drugs and radiation. The curricula can be downloaded at (http://www.estro-education.org/europeantraining/Pages/EuropeanCurricula.aspx). Conclusion: The main objective of the ESTRO core curricula is to update and harmonise training of the radiation oncologists, medical physicists and RTTs in Europe. It is recommended that the authorities in charge of the respective training programmes throughout Europe harmonise their own curricula according to the common framework.

  12. Bundling in Place: Translating the NGSS into Place-Based Earth-System Science Curricula

    Science.gov (United States)

    Semken, S. C.

    2016-12-01

    Bundling is the process of grouping Performance Expectations (PEs) from the Next Generation Science Standards (NGSS) into coherent units based on a defined topic, idea, question, or phenomenon. Bundling sorts the PEs for a given grade or grade band into a teachable narrative: a key stage in building curriculum, instruction, and assessment from the NGSS. To encourage and facilitate this, bundling guidelines have recently been released on the NGSS website (nextgenscience.org/glossary/bundlesbundling), and example bundles for different grade bands and disciplines are also being developed and posted there. According to these guidelines the iterative process of bundling begins with organization of PEs according to natural connections among them, and alignment of the three NGSS dimensions (Disciplinary Core Ideas, Cross-Cutting Concepts, and Science and Engineering Practices) that underpin each PE. Bundles are grouped by coherence and increasing complexity into courses, and courses into course sets that should encompass all PEs for a grade band. Bundling offers a natural way to translate the NGSS into highly contextualized curricula such as place-based (PB) teaching, which is situated in specific places or regions and focused on natural and cultural features, processes, phenomena, history, and challenges to sustainability therein. Attributes of place and our individual and collective connections to place (sense of place) directly inform PB curriculum, pedagogy, and assessment. PEs can be bundled by their relevance to these themes. Following the NGSS guidelines, I model the process for PB instruction by bundling PEs around the themes of Paleozoic geology and carbonate deposition and their relationships to mining and calcining of limestone in Anthropocene cement production for developing communities. The bundles integrate aspects of Earth history, the carbon cycle, mineral resources, climate change, and sustainability using specific local examples and narratives. They are

  13. Development of perceived instrumentality for mathematics, reading and science curricula

    Science.gov (United States)

    Garcia, Steve L.

    Perceptions of instrumentality (PI) are the connections one sees between a current activity and a future goal. With high PI, one is motivated to persist with quality effort because the current activity, even when difficult, is perceived as aligned with, and progress toward, the goal. Conversely, with low PI, one is motivated to relinquish effort in pursuit of other, more meaningful goals. In view of the alarming dropout rates in this country, it appears that PI research has much to offer in understanding students' motivations to stay in school and hence to become employed in their field of choice. Because academic achievement motivation can be affected by gender and ethnicity, particularly for specific components of the curriculum, and because curricular content varies across grade levels and school settings, this line of research offers significant potential for understanding and improving student outcomes. This research examined the development of PI among suburban 6th, 8th, 10th and 12th graders from a school district in the southwestern United States. Twelve hundred students completed a one-time paper and pencil survey measuring the perceived instrumentality of mathematics, literacy and science courses in terms of the students' occupational choices. MANOVA was used to determine factors that may affect students' overall PI and individual subject PI. Grade, gender, ethnicity, occupational choice, expectancy and value were the independent variables. A school setting variable was examined for effects on 12th graders. For the 8th through 12th grade sample, significant main effects were observed for grade, gender, minority status, occupational choice and expectancy on PI. Results show that PI is highest in the 6 th grade. Males reported higher Math PI than females. Females reported higher Reading PI and Science PI than males. Minority students reported lower overall PI and Science PI than non-minority students. Students who aspire to professional careers report the

  17. Evidence-based practice in Physiotherapy curricula: A survey of Indian Health Science Universities

    Directory of Open Access Journals (Sweden)

    VRUSHALI P PANHALE

    2017-07-01

    Full Text Available Introduction: Evidence-based practice (EBP is the conscientious, explicit and judicious use of the current evidence in clinical decision making. The physiotherapy profession has expressed a commitment to the development and use of evidence. However, very little is known about the extent to which EBP is integrated in physiotherapy curricula in India. The purpose of this study was to describe integration of EBP in Indian physiotherapy programs. Methods: An observational study was conducted where a review of curricula of all Health Science Universities (HSU in India, offering an undergraduate (UG and post-graduate (PG degree program in physical therapy was conducted using a data abstraction sheet. It gathered data on inclusion of research components of EBP in the curricula, content and hours of teaching EBP, and assessment methods. Data were analyzed descriptively. Results: Curricula of fifteen HSU offering physiotherapy programs were reviewed. Contents relevant to EBP were incorporated from the 2nd yr to final year. Common courses included research methodology (84.61%, research project (69.23% and clinical management subjects (57.14%. No guidelines were given about adopting EBP in clinical practice. Didactic lectures were the mode of teaching (81.81%. Preferred method for assessing research projects was viva (44.44%. Critical appraisal was least included in the entry level education. Contents relevant to all the five steps of EBP were included in PG curricula. Conclusions: Though physiotherapy programs are introducing EBP teaching at the entry level, it lacks structured systematic approach and is fragmented. There is inadequate emphasis on clinical oriented teaching of EBP and assessment methods. Moreover, there is adequate coverage of EBP content in PG curricula.

    2016-03-01

    Medical simulation offers the advantage of improving resident skill and comfort without impacting patient care. Five years ago, we identified trends in the use of robotic and laparoscopic simulation in 2008 and 2009 at American urology residency training programs. We seek to identify the changes in the use of simulators and the presence of formal curricula in the wake of technological advances and changes in graduate medical education. Attendees of the American Urological Association (AUA) Basic Sciences Course, mostly in their second or third year of residency, were surveyed on the availability and use of laparoscopic/robotic simulators at their program, the presence of a formal curriculum, and a Likert scale questionnaire regarding face and content validity. Over a 5-year period, the availability of virtual reality robotic simulators substantially increased from 14% to nearly 60% availability in 2013. Despite this increase, the frequency of simulator use remained unchanged (p = 0.40) and the reported presence of formal curricula decreased from 41% to 34.8%. There was no significant difference in simulator use between residents in programs with or without laparoscopic/robotic curricula (p = 0.95). There was also a decrease in the percentage of residents who felt official laparoscopic curricula (93%-81%) and simulators (82%-74%) should be involved in resident education. In the past 5 years, despite evidence supporting benefits from simulator use and increasing availability, self-reported resident use has remained unchanged and the reporting of presence of laparoscopic/robotic curricula has decreased. With more dedicated investment in formal curricula, residency training programs may receive greater returns on their simulator investments, improve resident skills and comfort, and ultimately improve the quality of patient care.

  3. Are Attitudes Toward Writing and Reading Separable Constructs? A Study With Primary Grade Children

    Science.gov (United States)

    Graham, Steve; Berninger, Virginia; Abbott, Robert

    2012-01-01

    This study examined whether or not attitude towards writing is a unique and separable construct from attitude towards reading for young, beginning writers. Participants were 128 first-grade children (70 girls and 58 boys) and 113 third-grade students (57 girls and 56 boys). Each child was individually administered a 24 item attitude measure, which contained 12 items assessing attitude towards writing and 12 parallel items for reading. Students also wrote a narrative about a personal event in their life. A factor analysis of the 24 item attitude measure provided evidence that generally support the contention that writing and reading attitudes are separable constructs for young beginning writers, as it yielded three factors: a writing attitude factor with 9 items, a reading attitude factor with 9 parallel items, and an attitude about literacy interactions with others factor containing 4 items (2 items in writing and 2 parallel items in reading). Further validation that attitude towards writing is a separable construct from attitude towards reading was obtained at the third-grade level, where writing attitude made a unique and significant contribution, beyond the other two attitude measures, to the prediction of three measures of writing: quality, length, and longest correct word sequence. At the first-grade level, none of the 3 attitude measures predicted students’ writing performance. Finally, girls had more positive attitudes concerning reading and writing than boys. PMID:22736933

    Vogel, Kimberly A; Geelhoed, Michael; Grice, Kimatha O; Murphy, Douglas

    2009-01-01

    This study evaluated whether critical thinking ability can be improved through participation in occupational therapy (OT) and physical therapy (PT) curricula. The researchers compared levels of the critical thinking skills of OT and PT students at the beginning and end of their programs to determine whether changes occurred and to examine facets of the curricula that may have caused the differences. The curricula include teaching strategies of problem-based learning modules, small group discussion and problem-solving, case studies, clinical observation, and evidence-based practice assignments, as well as teaching about critical thinking as a process in itself. Fifty OT and PT students completed the Watson-Glaser Critical Thinking Appraisal at the beginning and end of 20 mos of the academic phase of their master's degree programs. Researchers analyzed the data using a one-way repeated-measures ANOVA. Results showed no differences between OT and PT students on the pretest or post-test and no differences for PT students between the pretest and post-test. OT students' scores increased significantly from pretest to post-test. The influence of the timing of teaching critical thinking skills in the resulting differences between the two curricula, as well as the validity of the Watson-Glaser Critical Thinking Appraisal is a valid measure of critical thinking changes in allied health students are discussed.

    2015-11-01

    The potential benefits of participation in extracurricular activities may be especially important for youth who are at risk for academic underachievement, such as low income Mexican-origin youth in the U.S. To advance understanding of factors that drive participation for this population, this study examined Mexican-origin youth's trajectories of participation in extracurricular activities across Grades 7-12 and tested theoretically-derived predictors of these trajectories. Participants were 178 adolescents (53.9 % Female, Mage = 12.28) and their mothers who separately completed in-home interviews. Youth reported the frequency of their participation across a range of extracurricular activities. Latent growth curve models of overall extracurricular activities participation, sports participation, and fine arts participation were individually estimated via structural equation modeling. The findings demonstrated developmental declines in overall participation and in sports participation. For fine arts, declines in participation in middle school were followed by subsequent increases during high school (a curvilinear pattern). Motivationally-salient predictors of participation trajectories included youth's traditional cultural values orientation (sports), the mothers' educational aspirations for the youth (sports, fine arts, overall activity), and youth gender (sports, fine arts). Overall, the results suggest variability in participation trajectories based on program type, and highlight the need for additional research to enhance our understanding of the impact of culturally-relevant predictors on participation over time.

    Full Text Available Purpose – The purpose of this paper is to introduce instruction of technical analysis on the undergraduate level that can coincide with traditional teachings of fundamental analysis. Design/methodology/approach – Through examples using the latest in security analysis technology, this paper illustrates the importance of technical security analysis. Findings – This research illustrates how technical analysis techniques may be used to make more significant investment decisions. Originality/value – Kirkpatrick and Dahlquist define technical analysis as a security analysis discipline for forecasting future direction of prices through the study of past market data primarily price and volume This form of analysis has stood in direct contrast to the fundamental analysis approach whereby actual facts of the company its industry and sector may be ignored. Understanding this contrast, much of academia has chosen to continue to focus its finance curricula on fundamental analysis techniques. As more universities implement trading rooms to reflect that of industry, they must recognize that any large brokerage trading group or financial institution will typically have both a technical analysis and fundamental analysis team. Thus, the need to incorporate technical analysis into undergraduate finance curricula.

    The aim of this study was to determine the esophageal transit time in control individuals and in chagasic patients with or without megaesophagus.A total of 148 patients were allocated in 6 groups according to serological diagnostic of Chagas disease and the degree of esophageal dilatation: A, control healthy individuals (n = 34, 22.9%); B, indeterminate form (n = 23, 15.5%); C, megaesophagus I (n = 37, 25.0%); D, megaesophagus II (n = 19, 12.8%); E, megaesophagus III (n = 21, 14.2%); and F, megaesophagus IV (n = 14, 9.5%). After 8-hour fasting, patients were asked to swallow 75 mL of barium sulfate solution. x-Rays were obtained after 8, 30, 60, and 90 seconds, 5, 10, 30, 60, and 90 minutes, 2, 6, 12, 24 hours, and at every 12 hours until no more contrast was seen in the esophagus. This was the transit time.The transit time varied from 8 seconds to 36 hours (median = 90 seconds). A linear correlation was observed between transit time and megaesophagus grade: 8 seconds in groups A and B, 5 minutes in C, 30 minutes in D, 2 hours in E, and 9:15 hours in F. Dysphagia was not reported by 60 of 114 (52.6%) patients with positive serological tests for Chagas disease (37/91-40.7%-of patients with megaesophagus I-IV grades). The esophageal transit time increased with the grade of megaesophagus.The esophageal transit time has a direct correlation with the grade of megaesophagus; dysphagia complaint correlates with the grade of megaesophagus. However, many patients with megaesophagus do not report dysphagia.

    Full Text Available Reinforcement is one of the strategies in classroom management, which is familiar among teachers. One of the types of reinforcement in social reinforcement is praise. Praise can function as a tool for instruction and for increasing social and academic behaviors. To be effective, the student must view the attention provided through praise as pleasurable or motivational. The design of this study was correlation design. The research participant was the tenth grade students of SMK Negeri 9 Samarinda. The purposes of this study are to find out how is relationship between the teacher’s praise and the English learning achievement tenth grade of SMK Negeri 9 Samarinda and is there any significant relationship between English teacher’s praise and English learning achievement. The researcher conducted observation for a month, distributed questionnaires and collected the result of achievement test from the teacher, as the instruments of this study. Then the collected data were analyzed in order to find out the manifestation of reinforcement applied by the teacher. After analyzing the data gained through the observation, the researcher found out that English teacher praise significantly correlate with the English learning achievement of tenth grade SMK Negeri 9 Samarinda (r-value: 0,442 > r-table: 0,334. From the questionnaire, it was found that the students showed positive response or opinion toward the implementation of reinforcement in their class for example teacher praises immediately, frequently, enthusiastically, by using eye contact, uses many kinds of word praise and explains the reason why he praises students.

    Full Text Available As the global demand for programmers is soaring, several countries have integrated programming into their K-12 curricula. Finding effective ways to engage children in programming education is an important objective. One effective method for this can be presenting learning materials via games, which are known to increase engagement and motivation. Current programming education games often focus on a single genre and offer one-size-fits-all experience to heterogeneous learners. In this study, we presented Minerva, a multi-genre (adventure, action, puzzle game to engage elementary school students in learning programming concepts. The game content is adapted to play and learning styles of the player to personalize the gameplay. We conducted a formative mixed-method evaluation of Minerva with 32 Korean 6th grade students who played the game and compared their learning outcomes with 32 6th grade students who studied the same concepts using handouts. The results indicated that, in terms of retention, learning was equally effective in both groups. Furthermore, the game was shown to facilitate engagement among the students. These results, together with uncovered issues, will guide Minerva’s further development.

    Full Text Available Objectives. Anxiety disorders are the most common childhood psychiatric disorders. Previous research suggests that South African rates may be high. Our study examined the prevalence and severity of anxiety and depression among Grade 11 and 12 learners attending schools in central Bloemfontein. Learners’ perception of the important stressors as well as the most relevant coping strategies were investigated. Methods. A cross-sectional study was conducted by using self-assessment rating scales and questionnaires. The Hospital Anxiety and Depression Scale (HADS was used to screen for anxiety and depressive symptoms. Participants were provided with an additional list of possible stressors and coping skills, from which they identified those applicable to themselves. All students enrolled in Grades 11 and 12 at the selected schools during August 2009 were eligible for inclusion. Results. Five hundred and fifteen learners participated in the study, of whom 32.0% presented with moderate or severe anxiety and 5.3% with moderate or severe depressive symptoms. Mild symptoms were reported by an additional 29.0% on the anxiety subscale and 14% on the depression subscale of the HADS. Academic workload was reported as the main source of stress (81.4%. Conclusions. Although the study has limitations in terms of methodology and size, resulting in undetermined validity, it indicates possible higher prevalence rates for anxiety and depression than in previous South African studies and worldwide prevalence rates for adolescents. Pupils were generally hesitant to seek help from formal assistance structures provided by the schools, and preferred discussing problems with parents or friends.

    We report the synthesis, isolation and structural characterization of several moderately air stable nido-metallaboranes that represent boron rich open cage systems. The reaction of [Cp*CoCl]2, (Cp* = η(5)-C5Me5), with [BH3·thf] in toluene at ice cold temperature, followed by thermolysis in boiling toluene produced [(Cp*Co)B9H13], 1 [(Cp*Co)2B8H12], 2 and [(Cp*Co)2B6H10] 3. Building upon our earlier reactivity studies on rhodaboranes, we continue to explore the reactivity of dicobalt analogues of octaborane(12) cluster 3 with [Fe2(CO)9] and [Ru3(CO)12] at ambient conditions that yielded novel fused clusters [Fe2(CO)6(Cp*Co)2B6H10], 4 and [Ru4(CO)11(Cp*Co)2B3H3], 5 respectively. In an attempt to synthesize a heterometallic metallaborane compound we performed the reaction of [(Cp*Rh)2B6H10], 6 with [Cp*IrH4] that yielded a Ir-Ir double bonded compound [(Cp*Ir)2H3][B(OH)4], 7. All the new compounds have been characterized by IR, (1)H, (11)B, (13)C NMR spectroscopy, and the molecular structures were unambiguously established by X-ray diffraction analysis.

    Creep strength of particle strengthened 9-12% Cr steels can be predicted by fundamental modelling. The creep strength is evaluated from the state of the microstructure during creep. Particle hardening at high temperatures can be predicted by taking dislocation climb across particles into account. Work hardening is calculated from immobile dislocations in subgrain interiors and at boundaries using the composite theory. Subgrain coarsening will lower the influence of the mechanically hard boundaries. Recovery in dislocation density is predicted through static recovery by climb and dynamic recovery by locking and dipole formation. Solid solution hardening is needed in order to explain the difference in creep strength between different 9-12% Cr steels. The accumulation of large atoms such as Mo and W will slow down the dislocation climb velocity, and thereby the microstructure recovery rate. 100000h rupture strength is predicted for X20, P91, P92 steels without any use of fitting parameters. The creep strength of P91 steel with different microstructure due to Al additions. Z-phase transformation and heat affected material is presented. (orig.)

  20. Sexual Dating Aggression Across Grades 8 Through 12: Timing and Predictors of Onset

    Reyes, H. Luz McNaughton; Foshee, Vangie A.

    2013-01-01

    Investigators have identified a number of factors that increase risk for physical and psychological dating abuse perpetration during adolescence, but as yet little is known about the etiology of sexual dating aggression during this critical developmental period. This is an important gap in the literature given that research suggests that patterns of sexual dating violence that are established during this period may carry over into young adulthood. Using a sample of 459 male adolescents (76% White, 19% Black), the current study used survival analysis to examine the timing and predictors of sexual dating aggression perpetration onset across grades 8 through 12. Risk for sexual dating aggression onset increased across early adolescence, peaked in the 10th grade, and desisted thereafter. As predicted based on the Confluence Model of sexual aggression, associations between early physical aggression towards peers and dates and sexual aggression onset were stronger for teens reporting higher levels of rape myth acceptance. Contrary to predictions, inter-parental violence, prior victimization experiences, and parental monitoring knowledge did not predict sexual dating aggression onset. Findings support the notion that risk factors may work synergistically to predict sexual dating aggression and highlight the importance of rape myth acceptance as a construct that should be addressed by violence prevention programs.

    1994-10-01

    Most sexuality education curricula developed the past 20 years were not thoroughly evaluated. This study provides results from a content analysis of 10 sexuality education curricula for junior and senior high school students. Nine nationally available sexuality education curricula and one curriculum guide comprised the sample. The basis for analysis was the Guidelines for Comprehensive Sexuality Education, developed by the Sex Information and Education Council of the U.S. (SIECUS) and an instrument developed to measure bias in the curricula. Trained coders found that Sex Respect and Teen Aid addressed less than half the topics suggested by the SIECUS guidelines. Several of the curricula contained gender and sexual orientation bias. Certain key concepts such as "Sexual Behavior" and "Society and Culture" were not adequately addressed by most of the curricula. Findings indicate that of 10 curricula, only six are considered acceptable for educating junior and senior high school students.

    2011-01-01

    Retrospective questions on educational attainment in national surveys and censuses tend to over-estimate high school graduation rates by 15 to 20 percentage points relative to administrative records. Administrative data on educational enrollment are, however, only available at the aggregate level (state, school district, and school levels) and the recording of inter-school transfers are generally incomplete. With access to linked individual-level administrative records from a very large “West Coast metropolitan school district” we track patterns of high school attrition and on-time high school graduation of individual students. Even with adjustments for the omission of out-of-district transfers (estimates of omission are presented), the results of this study show that failure in high school, as indexed by retention and attrition, are almost as common as on-time high school graduation. In addition to the usual risk factors of disadvantaged background, we find that the “9th grade shock”—an unpredicted decline in academic performance upon entering high school—is a key mechanism behind the continuing crisis of high school attrition.

    This study examined the effects of cooperative testing versus traditional or individual testing and the impacts on academic achievement, motivation toward science, and study time for 9th grade biology students. Research questions centered on weekly quizzes given in a flipped classroom format for a period of 13 weeks. The study used a mixed methods research design, which combined quantitative and qualitative data collection techniques. The study examined 66 students enrolled in three sections of a 9 th grade biology course at a private K-12 school. Students were randomly assigned to groups of three or four students. Weekly quizzes on regularly assigned curriculum material were provided from the flipped classroom videos. Six quizzes were randomly selected for each class to be in the cooperative testing format and six quizzes were randomly selected to be given individually or traditional-style testing format. Week 7 was reserved for administration of the mid-study questionnaire and no quiz was administered. Quantitative data collected included student grades on the 12 weekly quizzes. Qualitative data were also collected from pre-study, mid-study, and post-study questionnaires as well as semi-structured individual interviews and one focus group. Cooperative testing groups scored higher on the quizzes than when students took quizzes as individuals for five of the nine quizzes analyzed. Students did not score significantly higher than the best scorer in groups taking quizzes individually. For one quiz, the best scorer did better than the cooperative groups. Overall, cooperatively tested groups in some cases scored higher than the average of groups taking the quizzes individually, but the impact was not consistent across all quiz weeks. Difficulty level of the material, contextual factors, and ceiling effects are among potential explanations of the inconsistent outcomes. Across the study, motivation toward science stayed the same or increased depending on the aspect of

    The prognostic performance of the albumin-bilirubin (ALBI) grade in hepatocellular carcinoma (HCC) as an objective method of assessing liver function was investigated. Data from 2099 patients with HCC in Korea were collected and analyzed retrospectively. The discriminative performance of ALBI grade was compared with Child-Pugh (C-P) grade for different stages or treatments. The median follow up duration was 16.2 months (range: 1.0-124.9). The median survival times were 49.7 months for C-P grade A (65.8%), 12.4 months for C-P grade B (25.5%), and 4.2 months for C-P grade C (8.6%) (P < 0.001). The median survival times were 84.2 months for ALBI grade 1 (32.8%), 25.5 months for ALBI grade 2 (53.5%), and 7.7 months for ALBI grade 3 (13.7%) (P < 0.001). In early UICC stages, ALBI grade showed better discriminative performance than C-P grade. In curative treatments, ALBI grade also showed better discriminative performance than C-P grade (Harrell's C: 0.624 (C-P grade) vs 0.667 [ALBI grade]). ALBI grade provided better prognostic performance in survival analysis and better distribution of the grades than C-P grade in HCC, suggesting that ALBI grade could be a good alternative grading system for liver function in patients with HCC. © 2018 Wiley Periodicals, Inc.

    Bullying is a widespread and serious problem that might influence both mental and psychical well being as well as school performance and social life. The aim of this study was to describe the prevalence of bullying, mental health problems and psychical complaints among 10th and 12th grade students and to analyze the association between bullying, mental health problems and muscle and skeletal complaints. Two cross sectional studies of adolescents living in Oslo, Norway the first conducted in 2001 among 10th grade students (15/16 years old) and the second in 2004 among 12th grade students (18/19 years old). Both surveys were based on self report, were mostly school based and had almost identical questionnaires. There were around 3700 participants in both surveys, but the participation rate was lower in the latter survey (88 versus 80%). The Hopkins Symptoms Check List (HSCL-10) and the Strength and Difficulties Questionnaire (SDQ) were used to measure mental health problems. Bullying is decreasing both among boys and girls while the prevalence of internalized mental health problems are increasing from 10th to 12th grade. For muscle and skeletal pain there is a diverging trend between boys and girls, with an increase among girls and a decrease among boys. The highest Odds Ratios, as a measure for the association between bullying, mental health problems and pain, were found for internalized mental health problems at both 10th and 12th grade both for boys and girls. Both internalized and externalized mental health problems together with pain seem to be associated with bullying irrespective of school type and gender.

    To refine the Minnesota Grading System (MGS) using definitions from the Age-Related Eye Disease Studies (AREDS) into a nine-step grading scale (MGS-9). A nine-step grading scale descriptive analysis using three key phenotypic features (total drusen area, increased, and decreased pigmentation) of human eyebank eyes that were graded according to definitions from the AREDS criteria in order to harmonize studies of disease progression for research involving human tissue. From 2005 through February 2017, we have analyzed 1159 human eyes, procured from two eyebanks. Each macula was imaged using high-resolution, stereoscopic color fundus photography with both direct- and transillumination. Fundus images were digitally overlaid with a grading template and triangulated for foveal centration. We documented and stratified risk for each globe by applying the AREDS nine-step grading scale to the key clinical features from the MGS-9. We found a good distribution within the MGS categories (1-9) with few level eight globes. Eyes were processed within 12.1 ± 6.3, hours from the time of death through imaging, dissection, and freezing or fixation. Applying the MGS-9 to 331 pairs (662 eyes were simultaneously graded), 84% were within one-grading step and 93% within two steps of the fellow eye. We also document reticular pseudodrusen, basal laminar drusen, and pattern dystrophy. The MGS nine-step grading scale enables researchers using human tissue to refine the risk assessment of donor tissue. This analysis will harmonize results among researchers when grading human tissue using MGS criteria. Most importantly, the MGS-9 links directly to the known risk for progression from the AREDS.

    2012-01-01

    We carried out a prospective study comparing the performance of human papillomavirus (HPV) E6/E7 mRNA (PreTect HPV-Proofer; NorChip, Klokkarstua, Norway) and DNA (Amplicor HPV test; Roche Diagnostics, Basel, Switzerland) triage testing of women 6 to 12 months after atypical-squamous-cells-of-undetermined-significance (ASCUS) or low-grade-squamous-intraepithelial-lesion (LSIL) cytology in organized screening to predict high-grade cervical intraepithelial neoplasia of grade 2 or worse (CIN2+) between screening rounds. Between January 2005 and April 2008, 692 study women with screening-detected ASCUS/LSIL cytology 6 to 12 months earlier returned for HPV mRNA and DNA testing and repeat cytology. The median follow-up time was 3 years, using existing health care facilities. Follow-up test results were available for 625 women. Of the 145 CIN2+ cases detected during the study period, 95 (65.5%) were HPV mRNA positive 6 to 12 months after screening-detected ASCUS/LSIL, 44 (30.4%) were HPV mRNA negative, and 6 (4.1%) were invalid. The corresponding HPV DNA results were 139 (95.9%), 5 (3.4%), and 1 (0.7%), respectively. The cumulative incidences of CIN2+ 3 years after a negative HPV mRNA and DNA test were 10.3% (95% confidence interval [CI], 7.2 to 13.3%) and 1.8% (95% CI, 0.0 to 3.6%), respectively. The cumulative incidences of CIN2+ 3 years after positive HPV mRNA and DNA tests were 52.8% (95% CI, 40.1 to 60.1%) and 41.3% (95% CI, 35.5 to 46.6%), respectively. In conclusion, both positive HPV mRNA and DNA test results have a high enough long-term prediction of CIN2+ risk to consider referral to colposcopy as good practice when performed in delayed triage of women with ASCUS/LSIL cytology. In addition, the low CIN2+ risk among women with a negative Amplicor HPV test in our study confirms its safe use in a clinical setting. PMID:22518869

    2005-02-01

    The mechanical properties of medium Cr steels used in fossil fired power plants are very good because of their excellent high temperature microstructural stability. However, as the desire to increase the operating temperature (>650C) of the plant goes up, the need for steels that maintain their strength at these temperatures also increases. The mechanical properties of three medium Cr steels (0.08C-(9-12)Cr-1.2Ni-0.7Mo-3.0Cu-3.0Co-0.5Ti) were investigated through hardness, hot hardness and tensile measurements. The strength of the 9-12%Cr steels at room temperature after long-term isothermal aging (750C; 1000 hours) compares favorably with that of other power plant steels (e.g., P91). In addition, the elevated temperature strength and hot hardness also behave similarly. The mechanical behavior will be discussed in terms of the strength, elongation and tensile fracture characteristics.

  11. History of nuclear engineering curricula

    International Nuclear Information System (INIS)

    Murphy, G.

    1975-01-01

    With the realization that nuclear energy had a vast potential for peacetime development, universities throughout the country began to develop courses in nuclear energy. A pioneering educational effort was necessary because there was an inadequate number of trained faculty, no established curricula, no textbooks, and very little suitable equipment. Nevertheless, by the early 1950's, several programs in nuclear science and engineering were beginning to provide instruction to potential nuclear engineers. At that time, the American Society for Engineering Education (ASEE) established a nuclear committee to cooperate with the U. S. Atomic Energy Commission (AEC) in nuclear education matters. With the financial support of the AEC, textbook material was developed, faculty training programs were instituted, and funds were made available for equipment. Because of the large interest shown in the field, many colleges and universities began to develop nuclear engineering curricula. After a few years, the need arose for general guidelines in curricular development. This led to the development of a Committee on Objective Criteria in Nuclear Engineering Education in which ASEE and the American Nuclear Society cooperated with the support of AEC. The committee report emphasized basic science, nuclear energy concepts, and nuclear technology, which have continued to be the significant components of a nuclear engineering curriculum. The last ten years have brought increased emphasis on BS programs, the introduction of extensive computer-based instruction, and an increasing emphasis on the engineering aspects of nuclear reactor power systems

    The products of the lipoxygenase pathway, methyl jasmonic acid (MeJA) and (9Z)-12-hydroxy-9-dodecenoic acid (HDA), hardly changed the relative level of phosphorylated polypeptides (RLPPs) during 2 h of incubation: 15 and 17 kDa RLPPs were enhanced by HDA, but decreased by MeJA. RLPPs of 73 and 82 kDa were increased by both compounds. MeJA and HDA treatment induced specific and unspecific effects in some RLPPs. It was shown that HDA and MeJA increased protein kinase activity in the presence of 1 microM cAMP.

  17. Longitudinal Study of Career Cluster Persistence from 8th Grade to 12th Grade with a Focus on the Science, Technology, Engineering, & Math Career Cluster

    Science.gov (United States)

    Wagner, Judson

    Today's technology driven global economy has put pressure on the American education system to produce more students who are prepared for careers in Science, Technology, Engineering, and Math (STEM). Adding to this pressure is the demand for a more diverse workforce that can stimulate the development of new ideas and innovation. This in turn requires more female and under represented minority groups to pursue future careers in STEM. Though STEM careers include many of the highest paid professionals, school systems are dealing with exceptionally high numbers of students, especially female and under represented minorities, who begin but do not persist to STEM degree completion. Using the Expectancy-Value Theory (EVT) framework that attributes student motivation to a combination of intrinsic, utility, and attainment values, this study analyzed readily available survey data to gauge students' career related values. These values were indirectly investigated through a longitudinal approach, spanning five years, on the predictive nature of 8 th grade survey-derived recommendations for students to pursue a future in a particular career cluster. Using logistic regression analysis, it was determined that this 8 th grade data, particularly in STEM, provides significantly high probabilities of a 12th grader's average grade, SAT-Math score, the math and science elective courses they take, and most importantly, interest in the same career cluster.

    Research ethics training during post-graduate education is necessary to improve ethical standards in the design and conduct of biomedical research. We studied quality and quantity of research ethics training in the curricula of post-graduate programs in the medical science in I.R. Iran. We evaluated curricula of 125 post-graduate programs in medical sciences in I.R. Iran. We qualitatively studied the curricula by education level, including the Master and PhD degrees and analyzed the contents and the amount of teaching allocated for ethics training in each curriculum. We found no research ethics training in 72 (58%) of the programs. Among the 53 (42%) programs that considered research ethics training, only 17 programs had specific courses for research ethics and eight of them had detailed topics on their courses. The research ethics training was optional in 25% and mandatory in 76% of the programs. Post-graduate studies that were approved in the more recent years had more attention to the research ethics training. Research ethics training was neglected in most of the medical post-graduate programs. We suggest including sufficient amount of mandatory research ethics training in Master and PhD programs in I.R. Iran. Further research about quality of research ethics training and implementation of curricula in the biomedical institutions is warranted. © 2016 John Wiley & Sons Ltd.

    2017-08-01

    The link between perceived demands of school, stress and mental health in relation to gender is complex. The study examined, with two waves of longitudinal data at age 13 and age 16, how changes in perceived academic demands relate to changes in perceived stress, taking into account gender and cognitive ability, and to investigate how these factors affect the level of psychosomatic and depressive symptoms at the age of 16. A nationally representative sample including about 9000 individuals from the Swedish longitudinal Evaluation Through Follow up database born in 1998 was included. A growth modelling approach was applied to examine relations over time. The results show girls to have a considerably higher self-reported level of mental health problems at the end of compulsory school than boys. This gender difference is entirely accounted for by perceived school demands and stress in grades 6 and 9. Students who were stronger in inductive than vocabulary ability reported lower levels of perceived academic demands and less stress in grade 6. There is a need to develop interventions for minimizing the consequences of stress among adolescents and modify those particular aspects of academic demands which cause stress and poor mental health, especially among girls.

    Early familiarity is regarded as one of the keys to attracting female students to traditionally male professions. I will describe four different extra curricular programs that my collaborators in the local school district and I have developed for students in grades 5-12. These programs are part of a project entitled "Promoting Young Women in the Physical sciences", which also includes teacher training and programs in which parents participate with the child. Through these sustained and broad-based interventions, we provide early experiences that we expect will prove positive to students. I will also address the successes and difficulties in starting and sustaining these programs.

  6. Tale of two curricula: The performance of 2000 students in introductory electromagnetism

    Directory of Open Access Journals (Sweden)

    Matthew A. Kohlmyer

    2009-10-01

    Full Text Available The performance of over 2000 students in introductory calculus-based electromagnetism (E&M courses at four large research universities was measured using the Brief Electricity and Magnetism Assessment (BEMA. Two different curricula were used at these universities: a traditional E&M curriculum and the Matter & Interactions (M&I curriculum. At each university, postinstruction BEMA test averages were significantly higher for the M&I curriculum than for the traditional curriculum. The differences in post-test averages cannot be explained by differences in variables such as preinstruction BEMA scores, grade point average, or SAT Reasoning Test (SAT scores. BEMA performance on categories of items organized by subtopic was also compared at one of the universities; M&I averages were significantly higher in each topic. The results suggest that the M&I curriculum is more effective than the traditional curriculum at teaching E&M concepts to students, possibly because the learning progression in M&I reorganizes and augments the traditional sequence of topics, for example, by increasing early emphasis on the vector field concept and by emphasizing the effects of fields on matter at the microscopic level.

  7. Cas9 versus Cas12a/Cpf1: Structure-function comparisons and implications for genome editing.

    Science.gov (United States)

    Swarts, Daan C; Jinek, Martin

    2018-05-22

    Cas9 and Cas12a are multidomain CRISPR-associated nucleases that can be programmed with a guide RNA to bind and cleave complementary DNA targets. The guide RNA sequence can be varied, making these effector enzymes versatile tools for genome editing and gene regulation applications. While Cas9 is currently the best-characterized and most widely used nuclease for such purposes, Cas12a (previously named Cpf1) has recently emerged as an alternative for Cas9. Cas9 and Cas12a have distinct evolutionary origins and exhibit different structural architectures, resulting in distinct molecular mechanisms. Here we compare the structural and mechanistic features that distinguish Cas9 and Cas12a, and describe how these features modulate their activity. We discuss implications for genome editing, and how they may influence the choice of Cas9 or Cas12a for specific applications. Finally, we review recent studies in which Cas12a has been utilized as a genome editing tool.

  8. Laboratory studies of the corrosion and mechanical properties of titanium grade-12 under WIPP repository conditions

    International Nuclear Information System (INIS)

    Sorensen, N.R.

    1990-01-01

    The author reviews laboratory work done at the Sandia Laboratories on the properties of titanium grade 12. The effect of gamma radiation on corrosion and mechanical properties has been investigated; no real effect has been detected on corrosion rate, Charpy impact energy, or tensile properties at 90 degrees and 10 4 rad/h. No structural changes are evident under examination by SEM or TEM. There is also no evidence of crevice corrosion after five years of exposure. The effect of radiation on hydrogen uptake was also investigated. Radiation appears to reduce the extent of uptake. The microstructure of titanium-12 changes with the addition of hydrogen to a structure with alternating layers of alpha and beta phase. A decrease in mechanical properties is associated with this change

  16. Quantitative evaluation of flexibility in undergraduate engineering curricula in the United Arab Emirates

    Directory of Open Access Journals (Sweden)

    Naif A. Darwish

    2016-03-01

    Full Text Available In academia, smooth progression of students significantly depends on the way curricula are developed and organized. Curricula or study plans with high degree of interconnectivity between courses, multiple prerequisites, and hierarchically structured courses tend to complicate the smooth progress of the enrolled students. In this work, a rigorous quantitative relaxation indicator, developed and published elsewhere by the first author, has been applied to quantify the degree of stiffness and rigidity in undergraduate engineering curricula at the American University of Sharjah (AUS, the University of Sharjah (UOS, United Arab Emirates University (UAEU, and the Petroleum Institute (PI, which are the leading universities in the United Arab Emirates. Results indicate high rigidity (low relaxation indices due to high degree of interconnectivity between courses, specifically in the second year of the study plans. The chemical engineering curriculum at PI exhibited the least flexibility due to very strong pre-and-co-requisite ties while the civil & environmental curriculum at UAEU showed the highest flexibility. The curricula considered require immediate attention and reorganization in order to facilitate smooth sequential progress of the students from one semester to another. A list of courses that require relaxation of strong pre-and corequisites ties has been presented for each curriculum.

  17. Dysfunctional problem-based learning curricula: resolving the problem

    Directory of Open Access Journals (Sweden)

    Lim William K

    2012-09-01

    Full Text Available Abstract Background Problem-based learning (PBL has become the most significant innovation in medical education of the past 40 years. In contrast to exam-centered, lecture-based conventional curricula, PBL is a comprehensive curricular strategy that fosters student-centred learning and the skills desired in physicians. The rapid spread of PBL has produced many variants. One of the most common is 'hybrid PBL' where conventional teaching methods are implemented alongside PBL. This paper contends that the mixing of these two opposing educational philosophies can undermine PBL and nullify its positive benefits. Schools using hybrid PBL and lacking medical education expertise may end up with a dysfunctional curriculum worse off than the traditional approach. Discussion For hybrid PBL schools with a dysfunctional curriculum, standard PBL is a cost-feasible option that confers the benefits of the PBL approach. This paper describes the signs of a dysfunctional PBL curriculum to aid hybrid PBL schools in recognising curricular breakdown. Next it discusses alternative curricular strategies and costs associated with PBL. It then details the four critical factors for successful conversion to standard PBL: dealing with staff resistance, understanding the role of lectures, adequate time for preparation and support from the administrative leadership. Summary Hybrid PBL curricula without oversight by staff with medical education expertise can degenerate into dysfunctional curricula inferior even to the traditional approach from which PBL emerged. Such schools should inspect their curriculum periodically for signs of dysfunction to enable timely corrective action. A decision to convert fully to standard PBL is cost feasible but will require time, expertise and commitment which is only sustainable with supportive leadership.

  18. `Hard science': a career option for socially and societally interested students? Grade 12 students' vocational interest gap explored

    Struyf, Annemie; Boeve-de Pauw, Jelle; Van Petegem, Peter

    2017-11-01

    A key theme in science education research concerns the decline in young peoples' interest in science and the need for professionals in hard science. Goal Congruity Theory posits that an important aspect of the decision whether to pursue hard science for study or as a career is the perception that hard science careers do not fulfil social (working with people) and societal (serving or helping others) interests. In this qualitative study, we explore grade 12 students' perceptions about the social and societal orientation of hard science careers. Furthermore, we investigate the variation in students' social and societal interests. Six focus groups were conducted with 58 grade 12 students in Flanders. Our results indicate that a number of students hold stereotypical views about hard science careers' social orientation, while others believe cooperation with others is an important aspect of hard science careers nowadays. Furthermore, our results show that students believe hard science careers can be societally oriented in the sense that they often associate them with innovation or societal progress. Finally, our results indicate that students may differentiate direct versus indirect societal orientation. These findings contribute to literature regarding social and societal interests and students' perceptions of hard science careers.

    Descriptive online observational survey. To identify the extent of thrust joint manipulation (TJM) integration into first-professional physical therapy program curricula. The most recent survey of TJM curricula was published in 2004, with a wide variation in faculty responses noted. Since that time, faculty resources have been developed and TJM language in "A Normative Model of Physical Therapist Professional Education" from the American Physical Therapy Association has been updated, leaving the current status of TJM education in curricula unknown. Faculty from 205 accredited physical therapy programs were invited to participate in an anonymous 35-item electronic survey during the summer of 2012. Seventy-two percent of programs responded to the survey, with 99% of programs teaching TJM and 97% of faculty believing TJM to be an entry-level skill. Cervical spine TJM is still being taught at a lower rate than techniques for other body regions. Faculty deemed 91% and 77% of students, respectively, at or above entry-level competency for implementing TJM in their clinical practice upon graduation. Most respondents indicated that increased utilization of TJM during clinical affiliations (78%) and lab hours (78%) would be beneficial to the student's knowledge/application of TJM. The utilization of TJM and faculty perceptions in first-professional physical therapy programs in the United States have evolved over the past decade. With TJM content more fully integrated into educational curricula, programs can now look to refine teaching strategies that enhance learning outcomes.

    2009-01-01

    Full Text Available Romania occupied a back position in the international tests on Mathematics and Sciences. Teachers stress out that one possible cause of this situation could be finding on the Mathematics and Sciences curricula. This paper presents the results of the comparisons of the Romanian curricula with the curricula promoted by the international testing (PISA 2000, 2003 and 2006, and TIMSS 1995, 1999, 2003, 2007 and the curricula of the countries occupied the first places in these tests. The comparisons underline those curricula approaches, which insure success on these tests and realize the reasons of the lack of success of the Romanian pupils. These results will be presented to the curriculum makers, universities and schools, to identify the specific and transferable competencies of the pupils with success in the above-mentioned disciplines.

    Executive functions (EFs) develop over the period of early childhood and adolescence up until young adulthood. Individual children differ substantially in the pace at which their EFs develop, and characteristics such as sex and the level of parental education (LPE) are thought to contribute to these differences. In the present study, we assessed age-related changes in EFs as perceived and evaluated by teachers and parents as well as the influence of sex and LPE on their evaluations. We used a newly developed observer-report questionnaire, the Amsterdam Executive Function Inventory (AEFI). The AEFI assesses three important components of the executive aspects of daily life behavior in 13 questions: Attention; Self-control and Self-monitoring; and Planning and Initiative taking. Teachers and parents evaluated these aspects of executive functioning in 186 schoolchildren in grades 3-6 (age: 9-12 years). Age effects within grades and differences in social economic status between the four participating schools were controlled. Results showed a significant increase in teacher-perceived EFs from third to fourth grades and from fifth to sixth grades. This development was influenced both by the sex of the child and by the LPE. As perceived by teachers, the component self-control and self-monitoring was higher for girls than for boys, and planning abilities were higher for children from families with a higher LPE. Additional analyses showed that there is a systematic and statistically significant difference between the evaluations of the teachers and that of parents. Parents reported higher scores for planning, whereas teachers reported higher scores for self-control and self-monitoring. Evaluations by parents and teachers were different for girls, but not for boys. These findings are important because they imply that the development of EFs as perceived by parents and teachers is influenced by child-related factors. Second, there are clear differences in evaluations between

    Cheng, Huai Yong; Davis, Molly

    2017-02-01

    Prior reviews of geriatrics curricula for internal medicine (IM) and family medicine (FM) residents have not evaluated study quality or assessed learning objectives or specific IM or FM competencies. This review of geriatrics curricula for IM and FM residents seeks to answer 3 questions: (1) What types of learning outcomes were measured? (2) How were learning outcomes measured? and (3) What was the quality of the studies? We evaluated geriatrics curricula that reported learning objectives or competencies, teaching methods, and learning outcomes, and those that used a comparative design. We searched PubMed and 4 other data sets from 2003-2015, and assessed learning outcomes, outcome measures, and the quality of studies using the Medical Education Research Study Quality Instrument (MERSQI) and Best Evidence Medical Education (BEME) methods. Fourteen studies met inclusion criteria. Most curricula were intended for IM residents in the inpatient setting; only 1 was solely dedicated to FM residents. Median duration was 1 month, and minimum geriatrics competencies covered were 4. Learning outcomes ranged from Kirkpatrick levels 1 to 3. Studies that reported effect size showed a considerable impact on attitudes and knowledge, mainly via pretests and posttests. The mean MERSQI score was 10.5 (range, 8.5-13) on a scale of 5 (lowest quality) to 18 (highest quality). Few geriatrics curricula for IM and FM residents that included learning outcome assessments were published recently. Overall, changes in attitudes and knowledge were sizeable, but reporting was limited to low to moderate Kirkpatrick levels. Study quality was moderate.

  20. Hidden in plain sight: the formal, informal, and hidden curricula of a psychiatry clerkship.

    Wear, Delese; Skillicorn, Jodie

    2009-04-01

    To examine perceptions of the formal, informal, and hidden curricula in psychiatry as they are observed and experienced by (1) attending physicians who have teaching responsibilities for residents and medical students, (2) residents who are taught by those same physicians and who have teaching responsibilities for medical students, and (3) medical students who are taught by attendings and residents during their psychiatry rotation. From June to November 2007, the authors conducted focus groups with attendings, residents, and students in one midwestern academic setting. The sessions were audiotaped, transcribed, and analyzed for themes surrounding the formal, informal, and hidden curricula. All three groups offered a similar belief that the knowledge, skills, and values of the formal curriculum focused on building relationships. Similarly, all three suggested that elements of the informal and hidden curricula were expressed primarily as the values arising from attendings' role modeling, as the nature and amount of time attendings spend with patients, and as attendings' advice arising from experience and intuition versus "textbook learning." Whereas students and residents offered negative values arising from the informal and hidden curricula, attendings did not, offering instead the more positive values they intended to encourage through the informal and hidden curricula. The process described here has great potential in local settings across all disciplines. Asking teachers and learners in any setting to think about how they experience the educational environment and what sense they make of all curricular efforts can provide a reality check for educators and a values check for learners as they critically reflect on the meanings of what they are learning.

    As nursing education struggles to address a rapidly changing health care system, overcrowded curricula, and an increased focus on clinical reasoning skills, many programs have adopted or transitioned to concept-based curricula (CBCs), which are structured around key concepts and exemplars. Despite CBC's promised benefits, the process of developing a CBC framework may pose a challenge to programs. To address this barrier, a national study was conducted to develop a representative list of concepts and exemplars. This initiative expands on prior work by suggesting a leveled approach to positioning exemplars within a curricular sequence.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

    2003-06-01

    A hierarchical linear model was used to estimate the individual and school level effects for marijuana use among a national sample of 12th-grade students. School effects were small in comparison to individual level effects, accounting for 2.9% of the variance in marijuana use. At the individual level, perceived harm, perceived availability, and their interaction were significant predictors, each of which varied randomly across schools. Among two school-level predictors, the normative environment for perceived harm was not significant, but normative perceived availability predicted level of marijuana use. The effect of perceived availability on marijuana use was stronger in larger, compared to smaller communities. Results are discussed in light of the use of random regression methods for identifying school-specific patterns of risk and protection for prevention planning.

    Retrospective review of a radiographic database of high-grade spondylolisthesis patients in comparison with asymptomatic controls. To analyze the sagittal spinopelvic alignment in high-grade spondylolisthesis patients and identify subgroups that may require reduction to restore sagittal balance. High-grade spondylolisthesis is associated with an abnormally high pelvic incidence (PI); however, the spatial orientation of the pelvis, determined by sacral slope (SS) and pelvic tilt (PT), is not known. We hypothesized that sagittal spinal alignment would vary with the pelvic orientation. Digitized sagittal radiographs of 133 high-grade spondylolisthesis patients (mean age, 17 years) were measured to determined sagittal alignment. K-means cluster analysis identified 2 groups based on the PT and SS, which were compared by paired t test. Comparisons were made to asymptomatic controls matched for PI. High-grade spondylolisthesis patients had a mean PI of 78.9 degrees +/- 12.1 degrees . Cluster analysis identified a retroverted, unbalanced pelvis group with high PT (36.5 degrees +/- 8.0 degrees )/low SS (40.3 degrees +/- 9.0 degrees ) and a balanced pelvic group with low PT (mean 21.3 degrees +/- 8.2 degrees )/high SS (59.9 degrees +/- 11.2 degrees ). The retroverted pelvis group had significantly greater L5 incidence and lumbosacral angle with less thoracic kyphosis than the balanced pelvic group. A total of 83% of controls had a "balanced pelvis" based on the categorization by SS and PT. Analysis of sagittal alignment of high-grade spondylolisthesis patients revealed distinct groups termed "balanced" and "unbalanced" pelvis. The PT and SS were similar in controls and balanced pelvis patients. Unbalanced pelvis patients had a sagittal spinal alignment that differed from the balanced pelvis and control groups. Treatment strategies for high-grade spondylolisthesis should reflect the different mechanical strain on the spinopelvic junction in each group; reduction techniques

    Since the early 1990s there has been a burgeoning interest in global health teaching in undergraduate medical curricula. In this article we trace the evolution of this teaching and present recommendations for how the discipline might develop in future years. Undergraduate global health teaching has seen a marked growth over the past ten years, partly as a response to student demand and partly due to increasing globalization, cross-border movement of pathogens and international migration of health care workers. This teaching has many different strands and types in terms of topic focus, disciplinary background, the point in medical studies in which it is taught and whether it is compulsory or optional. We carried out a survey of medical schools across the world in an effort to analyse their teaching of global health. Results indicate that this teaching is rising in prominence, particularly through global health elective/exchange programmes and increasing teaching of subjects such as globalization and health and international comparison of health systems. Our findings indicate that global health teaching is moving away from its previous focus on tropical medicine towards issues of more global relevance. We suggest that there are three types of doctor who may wish to work in global health - the 'globalised doctor', 'humanitarian doctor' and 'policy doctor' - and that each of these three types will require different teaching in order to meet the required competencies. This teaching needs to be inserted into medical curricula in different ways, notably into core curricula, a special overseas doctor track, optional student selected components, elective programmes, optional intercalated degrees and postgraduate study. We argue that teaching of global health in undergraduate medical curricula must respond to changing understandings of the term global health. In particular it must be taught from the perspective of more disciplines than just biomedicine, in order to reflect

    The excitation energy, spin and parity of levels in 13 C have been determined for excitation energies between 13 and 16 MeV via a phase-shift analysis of the measured total cross section, elastic differential cross section and analysing power for n + 12 C in the neutron energy range from 8.9 to 12.0 MeV. New analysing power measurements are reported for this energy range. The present and previous experimental data are well described by the phase shifts obtained. The non-elastic cross section for n + 12 C predicted from the phase shifts is in good agreement with the ENDF/B-V evaluation. The need for further experimental data is pointed out. (author)

    The transforming field of urological surgery continues to demand development of novel training devices and curricula for its trainees. Contemporary trainees have to balance workplace demands while overcoming the cognitive barriers of acquiring skills in rapidly multiplying and advancing surgical techniques. This article provides a brief review of the process involved in developing a surgical curriculum and the current status of real and simulation-based curricula in the 4 subgroups of urological surgical practice: open, laparoscopic, endoscopic, and robotic. An informal literature review was conducted to provide a snapshot into the variety of simulation training tools available for technical and nontechnical urological surgical skills within all subgroups of urological surgery using the following keywords: "urology, surgery, training, curriculum, validation, non-technical skills, technical skills, LESS, robotic, laparoscopy, animal models." Validated training tools explored in research were tabulated and summarized. A total of 20 studies exploring validated training tools were identified. Huge variation was noticed in the types of validity sought by researchers and suboptimal incorporation of these tools into curricula was noted across the subgroups of urological surgery. The following key recommendations emerge from the review: adoption of simulation-based curricula in training; better integration of dedicated training time in simulated environments within a trainee's working hours; better incentivization for educators and assessors to improvise, research, and deliver teaching using the technologies available; and continued emphasis on developing nontechnical skills in tandem with technical operative skills. © 2013 Published by Association of Program Directors in Surgery on behalf of Association of Program Directors in Surgery.

  13. Licensed physicians – competent physicians?: The new German licensure law as a basis for competency-based curricula

    Directory of Open Access Journals (Sweden)

    Öchsner, Wolfgang

    2005-01-01

    Full Text Available Background: Competency-based curricula define their educational goals according to profession-specific roles and competencies. Thus, this type of curricula is outcome-oriented, in contrast to the traditional German curricula, which are mainly procedure-oriented. This study investigates the new licensure legislation in Germany, mandatory for all medical faculties, to see if it allows the development of competency-based curricula.Methods: For the first step we clustered all demands to roles. In step two we transformed the procedure-oriented demands into outcome-oriented competencies, according to the 6 roles found, pursuing strictly the wording of the law.Results: Although the principal goals in the new German licensure law are outcome-oriented, namely three abilities of a certified physician, still the majority of requirements and demands remain procedure-oriented. Clustering resulted in the following six roles: medical expert, health advocate, teamworker, manager, representative of the medical profession and, life-long learner. The relevant competencies for the six roles, we could derive from the standards set by the law.Conclusion: We were able to show that the new German licensure order comprises a useful framework for the development of outcome-oriented, competency-based curricula.

  14. Differentiation of initial skills in 1st grade and the relative age effect in 3rd grade

    2017-06-01

    Full Text Available The paper aims to verify two hypotheses. The first states that the differentiation of initial 1st grade pupil skills is negatively correlated with age at entry to school. This was tested according to findings from the ERI study Six and seven year olds at the start of school. The variation of reading and writing scores of 1164 pupils aged 5.9–7.9 years who were beginning 1st grade decreased in subsequent age quartiles. The second hypothesis – that classroom differentiation of pupils’ initial skills in 1st grade is positively correlated with the birthdate effect in 3rd grade – was tested on data of 4838 pupils from 254 classrooms drawn from the 2011 PIRLS and TIMSS studies in Poland. Skills were evaluated on the basis of parental reports. Hierarchical linear analysis (gender, SES and school location controlled showed that the greater the differentiation of language skills in 1st grade, the greater the birthdate effect in mathematics in 3rd grade. This result suggests that school entry age is of lesser importance than the methods used to reduce differences in children’s school readiness at the onset of education.

  18. Hydrogen induced crack growth in Grade-12 titanium

    Ahn, T.M.; Lee, K.S.

    1984-01-01

    Internal hydrogen induced crack growth rates were measured in Grade-12 titanium which is a candidate material for high-level nuclear waste containers. As-received and hydrogen charged samples (5 ppM to 330 ppM hydrogen) were used for slow crack growth measurements at constant loads using a Krak Gauge. The testing temperature ranged from room temperature to 148 0 C. The crack growth kinetics under low to moderate loads are linear, but this linear rate is interrupted by discrete fast crack jump segments with parabolic or cubic type kinetics. These fast jump segments are thought to be associated with the passage of the crack front through the alpha-beta interface phase or with the initial loading sequence. By measuring striation spacings on the fracture surface, most crack growth rates observed are found to be in stage II. The striations are considered to be associated with hydride fracture. The crack path is either transgranular in the alpha phase or interfacial in the alpha phase adjacent to the beta phase. For transgranular growth, crack growth rates are constant and slower than those for interfacial growth which is associated with fast crack growth through a high hydrogen concentration region. Most stage II crack growth rates depend slightly on the stress intensity suggesting the contribution of plastic tearing process to stage II kinetics. The activation energies for crack growth are much lower than the activation energy of hydrogen diffusion through the alpha phase, implying that hydrogen is transported along dislocations, grain boundaries or interfaces. When the temperature is increased, the crack velocity first reaches a maximum and then decreases at higher temperatures. These temperature effects come from lower hydrogen concentration trapped at dislocations or from slower hydride nucleation kinetics, both at higher temperatures

    To assess whether the American Association for the Surgery of Trauma (AAST) grading system accurately corresponds with appendicitis outcomes in a US pediatric population. This single-institution retrospective review included patients appendicitis from 2008 to 2012. Demographic, clinical, procedural, and follow-up data (primary outcome was measured as Clavien-Dindo grade of complication severity) were abstracted. AAST grades were generated based on intraoperative findings. Summary, univariate, and multivariable regression analyses were performed to compare AAST grade and outcomes. Overall, 331 patients (46% female) were identified with a median age of 12 (IQR, 8-15) years. Appendectomy was laparoscopic in 90% and open in 10%. AAST grades included: Normal (n = 13, 4%), I (n = 152, 46%), II (n = 90, 27%), III (n = 43, 13%), IV (n = 24 7.3%), and V (n = 9 2.7%). Increased AAST grade was associated with increased Clavien-Dindo severity, P =.001. The overall complication rate was 13.6% and was comprised by superficial surgical site infection (n = 13, 3.9%), organ space infection (n = 15, 4.5%), and readmission (n = 17, 5.1%). Median duration of stay increased with AAST grade (P appendicitis grading system is valid in a single-institution pediatric population. Increasing AAST grade incrementally corresponds with patient outcomes including increased risk of complications and severity of complications.

  2. Ideological trends in initial teacher education curricula: the case of East African universities

    Directory of Open Access Journals (Sweden)

    Proscovia Namubiru Ssentamu

    2014-12-01

    Full Text Available This paper reviews the ideological trends in initial teacher education curricula in East African universities during the post-independent and contemporary times. From the mid-1960s and mid-1980s, initial teacher education curricula were integrated and harmonised with support from the East African Community whose efforts were coordinated by the Inter-University Council for East Africa. With the breakup of the Community in 1977, each independent state pursued its own educational strategy. However, underfunding of the public sector by governments, introduction of market-friendly reforms under the World Bank Structural Adjustment Programme in 1987 and the de-regularisation policies led to the liberalisation of public services, including education. Liberalisation affected among others, the quality of the initial teacher education curricula. Consequently, national councils and commissions for higher education were established to control standards in higher education, and the Inter-University Council for East Africa was revived to standardise and harmonise educational standards at regional level. The review shows that over the past five decades, the structure and organisation of initial teacher education curricula has continuously adjusted itself and been adjusted to a hybrid culture blending classical humanism, utilitarianism, social re-constructionism, market and global ideologies. Comparable ideological inclinations at socio-economic and political levels have influenced this trend in the region. The paper highlights the implications of such trends on the future of initial teacher education in the region.

    Purpose. To create a substantive mid-range theory explaining how the organizational cultures of undergraduate nursing programs shape the adoption and incorporation of mid-to high-level technical fidelity simulators as a teaching strategy within curricula. Method. A constructivist grounded theory was used to guide this study which was conducted in Ontario, Canada, during 2011-12. Semistructured interviews (n = 43) with participants that included nursing administrators, nursing faculty, and simulation leaders across multiple programs (n = 13) informed this study. Additionally, key documents (n = 67) were reviewed. Purposeful and theoretical sampling was used and data were collected and analyzed simultaneously. Data were compared among and between sites. Findings. The organizational elements that shape simulation in nursing (OESSN) model depicts five key organizational factors at the nursing program level that shaped the adoption and incorporation of simulation: (1) leaders working in tandem, (2) information exchange, (3) physical locale, (4) shared motivators, and (5) scaffolding to manage change. Conclusions. The OESSN model provides an explanation of the organizational factors that contributed to the adoption and incorporation of simulation into nursing curricula. Nursing programs that use the OESSN model may experience a more rapid or broad uptake of simulation when organizational factors that impact adoption and incorporation are considered and planned for.

    Full Text Available Abstract Background Problem-based Learning (PBL has been suggested as a key educational method of knowledge acquisition to improve medical education. We sought to evaluate the differences in medical school education between graduates from PBL-based and conventional curricula and to what extent these curricula fit job requirements. Methods Graduates from all German medical schools who graduated between 1996 and 2002 were eligible for this study. Graduates self-assessed nine competencies as required at their day-to-day work and as taught in medical school on a 6-point Likert scale. Results were compared between graduates from a PBL-based curriculum (University Witten/Herdecke and conventional curricula. Results Three schools were excluded because of low response rates. Baseline demographics between graduates of the PBL-based curriculum (n = 101, 49% female and the conventional curricula (n = 4720, 49% female were similar. No major differences were observed regarding job requirements with priorities for "Independent learning/working" and "Practical medical skills". All competencies were rated to be better taught in PBL-based curriculum compared to the conventional curricula (all p Conclusion Among medical graduates in Germany, PBL demonstrated benefits with regard to competencies which were highly required in the job of physicians. Research and business competence deserve closer attention in future curricular development.

    Management outcomes in poor-grade patients (World Federation of Neurological Surgeons Committee on a Universal Subarachnoid Hemorrhage Grading Scale Grade V) with ruptured cerebral aneurysms have historically been unsatisfactory. In the present study, we examined the possibility of intravascular treatment for ruptured aneurysm detected by 3-Dimensional CT angiography (3D-CTA) in poor-grade SAH patients. From April 1997 to July 2000, 3D-CTA was performed on 54 of 73 patients admitted with Grade V subarachnoid hemorrhage (SAH). Excluding 3 patients who underwent emergency surgery for ruptured aneurysms and intracerebral hematomas, CT findings from the remaining 51 patients were analyzed. The study included 23 men and 28 women, ranging in age from 28 to 91 with an average age of 63.6. The patients' initial scores on the Glasgow Coma Scale upon admission were 3 in 36 patients (including 19 patients who had undergone cardio-pulmonary arrest), 4 in 11 patients, 5 in 2 patients, and 6 in 2 patients. Ruptured aneurysms responsible for SAH were clearly delineated in 41 aneurysms from 39 patients, with 32 aneurysms in the anterior circulation and 9 in the posterior circulation. Patients with Glasgow Coma Scale of 4 or higher whose score did not progressively decrease for 12 hours after symptom onset were considered for intravascular treatment. In our study, 4 of 39 patients (10.3%) met these criteria. Glasgow Outcome Scale results were good recovery in 1 case, moderate disability in 1 case, severe disability in 1 case, and death in the remaining 48 cases. These results suggest that the management course for poor-grade (WFNS Grade V) SAH patients who retain brain stem reflexes contain the following: identification of aneurysms by 3D-CTA, maintenance of adequate sedation and external drainage to treat acute hydrocephalus, continued minimum 12-hour observation, monitoring levels of consciousness where possible, and consideration of aggressive therapy including

    1985-03-01

    The excitation energy, spin and parity of levels in /sup 13/C have been determined for excitation energies between 13 and 16 MeV via a phase-shift analysis of the measured total cross section, elastic differential cross section and analysing power for n + /sup 12/C in the neutron energy range from 8.9 to 12.0 MeV. New analysing power measurements are reported for this energy range. The present and previous experimental data are well described by the phase shifts obtained. The non-elastic cross section for n + /sup 12/C predicted from the phase shifts is in good agreement with the ENDF/B-V evaluation. The need for further experimental data is pointed out.

  18. The evolution of global health teaching in undergraduate medical curricula

    Directory of Open Access Journals (Sweden)

    Rowson Mike

    2012-11-01

    Full Text Available Abstract Background Since the early 1990s there has been a burgeoning interest in global health teaching in undergraduate medical curricula. In this article we trace the evolution of this teaching and present recommendations for how the discipline might develop in future years. Discussion Undergraduate global health teaching has seen a marked growth over the past ten years, partly as a response to student demand and partly due to increasing globalization, cross-border movement of pathogens and international migration of health care workers. This teaching has many different strands and types in terms of topic focus, disciplinary background, the point in medical studies in which it is taught and whether it is compulsory or optional. We carried out a survey of medical schools across the world in an effort to analyse their teaching of global health. Results indicate that this teaching is rising in prominence, particularly through global health elective/exchange programmes and increasing teaching of subjects such as globalization and health and international comparison of health systems. Our findings indicate that global health teaching is moving away from its previous focus on tropical medicine towards issues of more global relevance. We suggest that there are three types of doctor who may wish to work in global health – the ‘globalised doctor’, ‘humanitarian doctor’ and ‘policy doctor’ – and that each of these three types will require different teaching in order to meet the required competencies. This teaching needs to be inserted into medical curricula in different ways, notably into core curricula, a special overseas doctor track, optional student selected components, elective programmes, optional intercalated degrees and postgraduate study. Summary We argue that teaching of global health in undergraduate medical curricula must respond to changing understandings of the term global health. In particular it must be taught from the

    1987-01-01

    Miniature Charpy impact specimens of 9Cr-1MoVNb and 12Cr-1MoVW steels and these steels with 1 and 2% Ni were irradiated in the High-Flux Isotope Reactor (HFIR) at 50 0 C to displacement damage levels of up to 9 dpa. Nickel was added to study the effect of transmutation helium. Irradiation caused an increase in the ductile-brittle transition temperature (DBTT). The 9Cr-1MoVNb steels, with and without nickel, showed a larger shift than the 12Cr-1MoVW steels, with and without nickel. The results indicated that helium also increased the DBTT. The same steels were previously irradiated at higher temperatures. From the present and past tests, the effect of irradiation temperature on the DBTT behavior can be evaluated. For the 9Cr-1MoVNb steel, there is a continuous decrease in the magnitude of the DBTT increase up to an irradiation temperature of about 400 0 C, after which the shift drops rapidly to zero at about 450 0 C. The DBTT of the 12Cr-1MoVW steel shows a maximum increase at an irradiation temperature of about 400 0 C and less of an increase at either higher or lower irradiation temperatures

    Mospan, Cortney M

    To encourage the academy to pursue innovative management education strategies within pharmacy curricula and highlight these experiences in a scholarly dialogue. Management has often been a dreaded, dry, and often neglected aspect of pharmacy curricula. With the release of Center for Advancement of Pharmacy Education (CAPE) Educational Outcomes 2013 as well as Entry-Level Competencies Needed for Community Pharmacy Practice by National Association of Chain Drug Stores (NACDS) Foundation, National Community Pharmacists Association (NCPA), and Accreditation Council for Pharmacy Education (ACPE) in 2012, managerial skills have seen a new emphasis in pharmacy education. Further, management has greater emphasis within ACPE "Standards 2016" through adoption of CAPE Educational Outcomes 2013 into the standards. Previous literature has shown success of innovative learning strategies in management education such as active learning, use of popular television shows, and emotional intelligence. The academy must build a more extensive scholarly body of work highlighting successful educational strategies to engage pharmacy students in an often-dreaded subject through applying the Scholarship of Teaching and Learning.

    2012-01-01

    Constructive alignment theory has been used to underpin the development of curricula in higher education for some time (Biggs and Tang, 2007), however, its use to inform and determine skills curricula in nursing is less well documented. This paper explores the use of constructive alignment theory within a study of undergraduate student nurses undertaking clinical skill acquisition in the final year of a BSc (Hons) Nursing course. Students were followed up as newly qualified nurses (NQN) (n = 58) to ascertain the impact of skill acquisition in this way. Comparisons were made with newly qualified nurses who did not participate in a constructively aligned curriculum. This mixed methods study reported skill identification within the immediate post-registration period and evaluated the constructively aligned curriculum as having positive benefits for NQNs in terms of confidence to practice. This was supported by preceptors' views. The study recommends two process models for nursing skills curriculum development and reports that constructive alignment is a useful theoretical framework for nurse educators.

    Full Text Available The  The main objective of the present work is selection of ethical issues that should be addressed with first year undergraduate and K-12 students. Since K-12 Sciences’ curriculum, in Portugal, does not include bioethics content in any discipline explicitly, teachers need to make an effort to include it. Some online materials are available to use in high school classes and will be discussed. My proposal combines inquiry learning-teaching methods with the aim of promoting the discussion of bioethics issues in accordance to UNESCO Bioethics Core Curriculum already adopted by twenty universities throughout the world (Darwish 2015. Some of the issues that are addressed are: ecology and environment ethics, infectious diseases and vaccination, water for all, intellectual property, genomes and patents, biotechnological advances (genetic modified organisms and synthesis of genomes, future generations, climate hanges and natural resources, biomedical advances and human rights, authorship and contributions in scientific publications, and biobanks. In conclusion, this study may constitute an example to facilitate the implementation, by K-12 teachers, of active inquiry strategies, using features of science such as values and socio-scientific issues, and focused on the discussion of concrete ethical issues facing humanity. It also constitutes a proposal of integrating Bioethics in undergraduate sciences’ curricula.

    To highlight the four International Curricula of Ophthalmic Education developed by the Task Forces of the International Council of Ophthalmology, published in Klinische Monatsblätter für Augenheilkunde in November 2006. A global perspective of developing educational curricula as tools to improve eye care. Review of the experience and conclusions of the four international panels. The Task Force on Resident and Specialist Education developed a curriculum consisting of 15 topics in basic, standard, and advanced levels to provide flexibility of educational programs of the ophthalmic specialist in different locations across the world. The curricula were designed to be an educational tool to stimulate multiple levels of training of the ophthalmic specialist. The Task Force on Ophthalmic Education of Medical Students designed a curriculum covering 11 topics and provides illustrative materials for teachers and students. The Task Force strongly advocates the ophthalmology curriculum to be part of the core program of general medical schools education. The Task Force on Para-ophthalmic Vision Specialist Education developed a curriculum to highlight the importance of a team approach to eye care, consisting of ophthalmic specialists and paraophthalmic personnel to produce maximum efficiency. The Task Force on Continuing Medical Education (CME) designed a curriculum exploring the principles, elements, categories, and administration of CME activities in a variety of topics. These curricula shifted the traditional apprentice system of education to a curriculum-based training program in which goals, expectations, competencies, and technical training are defined to improve eye care worldwide.

    Standard clinical assessments do not predict surgical intervention in patients with a moderate degree of upper tract hydronephrosis. This study investigated whether combined measures of renal calyceal dilation and anteroposterior diameter (APD) of the renal pelvis at the first postnatal ultrasound better predict surgical intervention beyond standard assessments of the APD or Society of Fetal Urology (SFU) grading system. A retrospective cohort of 348 children with antenatal hydronephrosis followed from 2003 to 2013 were studied. Using Cox regression, the risk for surgery by APD, SFU, and combined grading on the basis of the first postnatal ultrasound was calculated. The predictive capability of each grading system for surgery was determined by calculating the positive likelihood ratio (LR+). The combination of APD≥6-9 mm and diffuse caliectasis had a hazard ratio (HR) of 19.5 (95% confidence interval [95% CI], 3.94 to 96.9) versus 0.59 (95% CI, 0.05 to 6.53) for APD≥6-9 mm alone and a similar risk of 8.9 for SFU grade 3 (95% CI, 3.84 to 20.9). The combination of APD≥9-15 mm and diffuse caliectasis had an HR of 18.7 (95% CI, 4.36 to 80.4) versus 1.75 (95% CI, 0.29 to 10.5) for APD≥9-15 mm alone. The LR+ for surgery for diffuse caliectasis and APD≥6-9 mm was higher than for APD≥6-9 mm alone (HR=2.62; 95% CI, 0.87 to 7.94 versus HR=0.04; 95% CI, 0.01 to 0.32) and was higher for APD≥9-15 mm and diffuse caliectasis than APD≥9-15 mm alone (HR=2.0; 95% CI, 1.15 to 3.45 versus HR=0.14; 95% CI, 0.04 to 0.43). Both combined groups of moderate hydronephrosis (APD≥6-9 mm or ≥9-15 mm with diffuse caliectasis) had only slightly higher LR+ than SFU grade 3 (HR=1.89; 95% CI, 1.17 to 3.05). These results suggest a grading system combining APD and diffuse caliectasis distinguishes those children with moderate degrees of upper tract hydronephrosis that are at higher risk of surgery.

    American Association for the Surgery of Trauma (AAST) Organ Injury Scale (OIS) grades IV and V complex hepatic injuries are highly lethal. Our objectives were to review experience and identify predictors of outcome and to evaluate the role of angioembolization in decreasing mortality. This was a retrospective 8-year study of all patients sustaining AAST-OIS grades IV and V hepatic injuries managed operatively. Statistical analysis was performed using univariate and multivariate logistic regression. The main outcome measure was survival. The study included 103 patients, with a mean Revised Trauma Score of 5.61 +/- 2.55 and a mean Injury Severity Score of 33 +/- 9.5. Mechanism of injury was penetrating in 80 (79%) and blunt in 23 (21%). Emergency department thoracotomy was performed in 21 (25%). AAST grade IV injuries occurred in 51 (47%) and grade V injuries occurred in 52 (53%). Mean estimated blood loss was 9,414 mL. Overall survival was 43%. Adjusted overall survival rate after emergency department thoracotomy patients were excluded was 58%. Results stratified to AAST-OIS injury grade were as follows: grade IV, 32 of 51 (63%); grade V, 12 of 52 (23%); grade IV versus grade V (p Trauma Score (adjusted p hepatic veins (adjusted p hepatic injuries.

    Studies have shown that number line estimation is important for learning. However, it is yet unclear if number line estimation predicts different mathematical skills in different grades after controlling for age, non-verbal cognitive ability, attention, and working memory. The purpose of this study was to examine the role of number line estimation on two mathematical skills (calculation fluency and math problem-solving) in grade 2 and grade 4. One hundred and forty-eight children from Shanghai, China were assessed on measures of number line estimation, non-verbal cognitive ability (non-verbal matrices), working memory (N-back), attention (expressive attention), and mathematical skills (calculation fluency and math problem-solving). The results showed that in grade 2, number line estimation correlated significantly with calculation fluency ( r = -0.27, p problem-solving ( r = -0.52, p problem-solving ( r = -0.38, p problem-solving (12.0%) and calculation fluency (4.0%) after controlling for the effects of age, non-verbal cognitive ability, attention, and working memory. In grade 4, number line estimation accounted for unique variance in math problem-solving (9.0%) but not in calculation fluency. These findings suggested that number line estimation had an important role in math problem-solving for both grades 2 and 4 children and in calculation fluency for grade 2 children. We concluded that number line estimation could be a useful indicator for teachers to identify and improve children's mathematical skills.

    For the purpose of arranging reference alloys available for various characterization efforts by Japanese fusion research groups, fabrication of reference 9Cr and 12Cr-ODS steels have been carried out with similar manufacturing processes followed by various characterizations. The fabrication proceeded with powder mixing, MA, encapsulation into mild steel cases, hot extrusion and hot forging, followed by final heat treatments. Each alloy was extruded into three bars. The characterization included chemical composition analysis, SEM and TEM microstructural observations, hardness tests, tensile tests at RT and 973 K, and relatively short-term thermal creep tests at 973 K. Room temperature hardness for 9Cr-ODS was larger than 12Cr-ODS, the former showing large increase when annealing temperature exceeded 1200 K and the latter showing no significant change with annealing temperature. Tensile strength of 9Cr-ODS was significantly larger than that of 12Cr-ODS at RT but comparable at 973 K. 9Cr-ODS showed longer and shorter creep rupture time than 12Cr-ODS at high and low stress levels, respectively. The mechanism of the difference in creep properties of the two alloys was discussed.

    The purpose of this study was to identify the risk of concomitant glenohumeral pathologies with acromioclavicular joint injuries grade III and V. Patients who underwent arthroscopically-assisted stabilization of acromioclavicular joint injuries grade III or grade V between 01/2007 and 12/2015 were identified in the patient databases of two surgical centres. Gender, age at index surgery, grade of acromioclavicular joint injury (Rockwood III or Rockwood V), and duration between injury and index surgery (classified as acute or chronic) were of interest. Concomitant glenohumeral pathologies were noted and their treatment was classified as debridement or reconstructive procedure. A total of 376 patients (336 male, 40 female) were included. Mean age at time of arthroscopic acromioclavicular joint reconstruction surgery was 42.1 ± 14.0 years. Overall, 201 patients (53%) had one or more concomitant glenohumeral pathologies. Lesions of the biceps tendon complex and rotator cuff were the most common. Forty-five patients (12.0%) had concomitant glenohumeral pathologies that required an additional repair. The remaining 156 patients (41.5%) received a debridement of their concomitant pathologies. Rockwood grade V compared to Rockwood grade III (p = 0.013; odds ratio 1.7), and chronic compared to acute injury were significantly associated with having a concomitant glenohumeral pathology (p = 0.019; odds ratio 1.7). The probability of having a concomitant glenohumeral pathology was also significantly associated with increasing age (p acromioclavicular joint injury of either grade III or V. Twenty-two percent of these patients with concomitant glenohumeral pathologies received an additional dedicated repair procedure. Although a significant difference in occurrence of concomitant glenohumeral pathologies was seen between Rockwood grades III and V, and between acute and chronic lesions, increasing age was identified as the most dominant predictor.

    Precipitation of Z-phase, Cr(V,Nb)N, is known to negatively affect creep properties of 9-12%Cr steels for power plant applications as it dissolves finely distributed MX particles, (V,Nb)N, especially in high Cr steels. As the Z-phase precipitates slowly as large particles, this causes a net drop ...... and crystallographically into Z-phase CrTaN particles. Copyright © 2014 Electric Power Research Institute, Inc.

    Kallikreins have clinical value as prognostic markers in a subset of malignancies examined to date, including kallikrein 3 (prostate specific antigen) in prostate cancer. We previously demonstrated that kallikrein 6 is expressed at higher levels in grade IV compared to grade III astrocytoma and is associated with reduced survival of GBM patients. In this study we determined KLK1, KLK6, KLK7, KLK8, KLK9 and KLK10 protein expression in two independent tissue microarrays containing 60 grade IV and 8 grade III astrocytoma samples. Scores for staining intensity, percent of tumor stained and immunoreactivity scores (IR, product of intensity and percent) were determined and analyzed for correlation with patient survival. Grade IV glioma was associated with higher levels of kallikrein-immunostaining compared to grade III specimens. Univariable Cox proportional hazards regression analysis demonstrated that elevated KLK6- or KLK7-IR was associated with poor patient prognosis. In addition, an increased percent of tumor immunoreactive for KLK6 or KLK9 was associated with decreased survival in grade IV patients. Kaplan-Meier survival analysis indicated that patients with KLK6-IR < 10, KLK6 percent tumor core stained < 3, or KLK7-IR < 9 had a significantly improved survival. Multivariable analysis indicated that the significance of these parameters was maintained even after adjusting for gender and performance score. These data suggest that elevations in glioblastoma KLK6, KLK7 and KLK9 protein have utility as prognostic markers of patient survival.

    Problem-based Learning (PBL) has been suggested as a key educational method of knowledge acquisition to improve medical education. We sought to evaluate the differences in medical school education between graduates from PBL-based and conventional curricula and to what extent these curricula fit job requirements. Graduates from all German medical schools who graduated between 1996 and 2002 were eligible for this study. Graduates self-assessed nine competencies as required at their day-to-day work and as taught in medical school on a 6-point Likert scale. Results were compared between graduates from a PBL-based curriculum (University Witten/Herdecke) and conventional curricula. Three schools were excluded because of low response rates. Baseline demographics between graduates of the PBL-based curriculum (n = 101, 49% female) and the conventional curricula (n = 4720, 49% female) were similar. No major differences were observed regarding job requirements with priorities for "Independent learning/working" and "Practical medical skills". All competencies were rated to be better taught in PBL-based curriculum compared to the conventional curricula (all p learning/working" (Delta + 0.57), "Psycho-social competence" (Delta + 0.56), "Teamwork" (Delta + 0.39) and "Problem-solving skills" (Delta + 0.36), whereas "Research competence" (Delta--1.23) and "Business competence" (Delta--1.44) in the PBL-based curriculum needed improvement. Among medical graduates in Germany, PBL demonstrated benefits with regard to competencies which were highly required in the job of physicians. Research and business competence deserve closer attention in future curricular development.

    Full Text Available The study aimed at answering the following key question: Are academic standards of political sciences fulfilled in the curricula of political science programs at the Palestinian universities? Accordingly, the study included a theoretical section that explained the basic concepts of quality in education, and some international experiences adopted for quality assurance of political sciences programs. Then the study analyzed, according to the standard criteria, the curricula of four departments that grant a bachelor's degree in political sciences, based on information published on the departments’ sites on the internet, and according to the academic guidebook of each department. The study concluded that the mission and objectives of three departments are clear, while the findings of the analysis showed that there is mismatch of requirements in the Palestinian curricula with academic standards. Most programs are rich with major materials, but need a little adjustment to conform to the standards. The findings also showed a number of negative points in study plans, which do not contain enough credit hours for scientific research, computer applications, and field training, while they have extra credit hours for university requirements. The study made several recommendations to address the problems of the curricula, including: Inviting departments to form committees to ensure quality, to modify the curricula, and develop it in accordance with international standards.

    Interference studies of four glucose meters (Nova Biomedical [Waltham, MA] StatStrip [hospital grade], Roche Diagnostics [Indianapolis, IN] Accu-Chek Aviva [home grade], Abbott Diabetes Care [Alameda, CA] Precision FreeStyle Freedom [home grade], and LifeScan [Milpitas, CA] SureStep Flexx [hospital grade]) were evaluated and compared to the clinical laboratory plasma hexokinase reference method (Roche Hitachi 912 chemistry analyzer). These meters were chosen to reflect the continuum of care from hospital to home grade meters commonly seen in North America. Within-run precision was determined using a freshly prepared whole blood sample spiked with concentrated glucose to give three glucose concentrations. Day-to-day precision was evaluated using aqueous control materials supplied by each vendor. Common interferences, including hematocrit, maltose, and ascorbate, were tested alone and in combination with one another on each of the four glucose testing devices at three blood glucose concentrations. Within-run precision for all glucose meters was glucose meters. Ascorbate caused differences (percentage change from a sample without added interfering substances) of >5% with pyrroloquinolinequinone (PQQ)-glucose dehydrogenase-based technologies (Aviva and Freestyle) and the glucose oxidase-based Flexx meter. Maltose strongly affected the PQQ-glucose dehydrogenase-based meter systems. When combinations of interferences (ascorbate, maltose, and hematocrit mixtures) were tested, the extent of the interference was up to 193% (Aviva), 179% (FreeStyle), 25.1% (Flexx), and 5.9% (StatStrip). The interference was most pronounced at low glucose (3.9-4.4 mmol/L). All evaluated glucose meter systems demonstrated varying degrees of interference by hematocrit, ascorbate, and maltose mixtures. PQQ-glucose dehydrogenase-based technologies showed greater susceptibility than glucose oxidase-based systems. However, the modified glucose oxidase-based amperometric method (Nova StatStrip) was

    Full Text Available Studies have shown that number line estimation is important for learning. However, it is yet unclear if number line estimation predicts different mathematical skills in different grades after controlling for age, non-verbal cognitive ability, attention, and working memory. The purpose of this study was to examine the role of number line estimation on two mathematical skills (calculation fluency and math problem-solving in grade 2 and grade 4. One hundred and forty-eight children from Shanghai, China were assessed on measures of number line estimation, non-verbal cognitive ability (non-verbal matrices, working memory (N-back, attention (expressive attention, and mathematical skills (calculation fluency and math problem-solving. The results showed that in grade 2, number line estimation correlated significantly with calculation fluency (r = -0.27, p < 0.05 and math problem-solving (r = -0.52, p < 0.01. In grade 4, number line estimation correlated significantly with math problem-solving (r = -0.38, p < 0.01, but not with calculation fluency. Regression analyses indicated that in grade 2, number line estimation accounted for unique variance in math problem-solving (12.0% and calculation fluency (4.0% after controlling for the effects of age, non-verbal cognitive ability, attention, and working memory. In grade 4, number line estimation accounted for unique variance in math problem-solving (9.0% but not in calculation fluency. These findings suggested that number line estimation had an important role in math problem-solving for both grades 2 and 4 children and in calculation fluency for grade 2 children. We concluded that number line estimation could be a useful indicator for teachers to identify and improve children’s mathematical skills.

    Today's nursing programs are struggling to accommodate the changing needs of the health care environment and need to make changes in how students are taught. Using constructivism theory, whereby learning is an active process in which learners construct new ideas or concepts based upon their current or past knowledge, leaders in nursing education can make a paradigm shift toward concept-based curricula. This article presents a summary and analysis of constructivism and an innovative application of its active-learning principles to curriculum development, specifically for the education of nursing students.

    Hepatocellular carcinoma (HCC) is a leading cause of liver-related mortality in people living with HIV, where co-infection with hepatotropic viruses accelerates the course of chronic liver disease. To evaluate whether the albumin-bilirubin (ALBI) grade, a more accurate marker of liver dysfunction in HCC, might identify patients with progressive liver dysfunction in the context of HIV/hepatitis co-infection. Using uni- and multi-variable analyses, we studied the albumin-bilirubin grade as a predictor of overall survival (OS) in a large, multi-center cohort of patients with HIV-associated HCC recruited from 44 centres in 9 countries within the Liver Cancer in HIV study group. Patients who underwent liver transplantation were excluded. A total of 387 patients, predominantly HCV co-infected (78%) with balanced representation of all Barcelona Clinic Liver Cancer (BCLC) stages (A = 33%, B = 18%, C = 37%, D = 12%) were recruited. At HCC diagnosis, 84% had been on anti-retrovirals for a median duration of 8.8 years. The albumin-bilirubin grade identified significant differences in median survival of 97 months for grade 1 (95% CI 13-180 months), 17 months for grade 2 (95% CI 11-22 months) and 6 months for grade 3 (95% CI 4-9 months, P bilirubin grade correlated with lower CD4 counts (464/373/288 cells/mm 3 for grades 1/2/3) and higher HIV viraemia (3.337/8.701/61.845 copies/mL for grades 1/2/3, P bilirubin grade highlights the interplay between liver reserve and immune dysfunction as prognostic determinants in HIV-associated HCC. © 2017 John Wiley & Sons Ltd.

    Initiating New Science Partnerships in Rural Education (INSPIRE), a NSF Graduate K-12 (GK-12) program at Mississippi State University, pairs STEM graduate students with local K-12 teachers to bring new inquiry and technology experiences to the classroom (www.gk12.msstate.edu). The graduate fellows prepare lessons for the students incorporating different facets of their research. The lessons vary in degree of difficulty according to the content covered in the classroom and the grade level of the students. The focus of each lesson is directed toward the individual research of the STEM graduate student using inquiry based designed activities. Scientific instruments that are used in STEM research (e.g. SkyMaster weather stations, GPS, portable SEM, Inclinometer, Soil Moisture Probe, Google Earth, ArcGIS Explorer) are also utilized by K-12 students in the activities developed by the graduate students. Creativity and problem solving skills are sparked by curiosity which leads to the discovery of new information. The graduate students work to enhance their ability to effectively communicate their research to members of society through the creation of research linked classroom activities, enabling the 7-12th grade students to connect basic processes used in STEM research with the required state and national science standards. The graduate students become respected role models for the high school students because of their STEM knowledge base and their passion for their research. Sharing enthusiasm for their chosen STEM field, as well as the application techniques to discover new ideas, the graduate students stimulate the interests of the classroom students and model authentic science process skills while highlighting the relevance of STEM research to K-12 student lives. The measurement of the student attitudes about science is gathered from pre and post interest surveys for the past four years. This partnership allows students, teachers, graduate students, and the public to

    2016-05-01

    Since the university education of psychologists began in Spain in 1954, the history of psychology course has been included in the curriculum. In the first few years, only half of the curricula offered the course. From 1973 to 2007, the universities' organization and regulation underwent successive reforms that involved changes in the curricula, decreeing specific national guidelines for each degree and establishing a minimum set of common required courses, called core courses, including the history of psychology. In 2007, the European Higher Education Area was set up, transforming the 5-year bachelor's degrees into 4-year degrees and eliminating the required guidelines, with each university being able to define the content of their curricula. The Dean's Conference for Psychology agreed on some recommendations related to core courses, which continued to include the history of psychology and were adopted by the majority of the universities. In 2015, the government established a new national regulation that makes it possible for each university to voluntarily reduce the length of the bachelor's degree to 3 years. Some psychology historians believe that this hypothetical reduction in the length of the degree, along with the already existing general tendency to prioritize applied or practical courses over basic or fundamental ones, could produce an appropriate scenario for the disappearance of the history of psychology course in some universities.

(MR) imaging features of a surgically confirmed case of LGFMS, affecting the shoulder is presented. A 30-year-old man presented with a 20-year history of a painless slow-growing mass in the right shoulder. Magnetic resonance images were obtained on a 2.0T scanner (Elscint, Haifa, Israel), demonstrating a well-defined soft tissue mass measuring 12.0 x 7.0 x 9.0 cm located between the deltoid muscle, rotator-cuff muscles, and proximal humerus. The differential diagnosis of LGFMS includes several benign and malignant neoplasms containing variable amounts of myxoid and fibrous tissue. Histologically, the most important differential diagnosis is with myxofibrosarcoma. Low-grade fibromyxoid sarcoma is a rare soft tissue tumor with slow growth and deceptively benign histologic appearance. The possibility of LGFMS must be considered when elaborating differential diagnostic possibilities for young adults with a large soft tissue mass exhibiting MR imaging characteristics of intermixed fibrous and myxoid tissue

The objective of this analysis was to discover the reading and listening activities that can sufficiently promote the levels of cognitive process. The activities determined as the criteria for analysis were: Wh-questions, true/false question, yes/no question, multiple choice question, complete the sentence phrase, a chart, matching questions, statement question, and a key word request question. The activities of the questions were gathered, listed with the total numbers of 161 questions and analyzed according to the six levels of New Bloom’s Taxonomy. The results showed that 98 activities emphasized mostly on lower levels cognitive order while only 63 activities emphasized the higher levels of thinking skills. So, the course book mentioned above targeted as a resource for students to learn the language, not as a resource for students to develop thinking skills because it fails to equip learners with the activities requiring higher levels of thinking order. By implication, for the teacher/syllabus designer can be aware to modify their own learning material by integrating more higher-order questions to achieve higher levels of thinking skills.

    The purpose of this study was to identify the relationship among critical thinking skill, gender and motivation in 9th grade students of Junior High School in Kuningan. This descriptive study used purposive sampling that comprised 110 ninth grade students taken from three junior high school that has good computer literacy and use 2013 curriculum. The data were obtained through Science Virtual Test on living things and environmental sustainability theme, respondent identity, and science motivation questionnaire (SMQ). Female students scored highest on generating purpose skill (M = 73.81), while male students performed better on generating implication and consequences skill (M = 78.01) where both groups differed significantly (p = 0.011). Students scored highest on generating purpose skill for high and moderate motivation group, while for the lowest score, moderate and low motivation group performed it on making assumption skill. Additionally, some critical thinking elements differed significantly by motivation to learn science. Despite, there was no correlation between students’ critical thinking and motivation (r = 0.155, p > 0.05). The finding indicated that students’ critical thinking is not differed by gender and not affected by motivation to learn science.

    The Center for Microbial Oceanography: Research and Education (C-MORE) is a NSF Science and Technology Center based at the University of Hawaii. The C-MORE education and outreach program offers a variety of resources and professional development opportunities for science educators, including online resources, participation in oceanography research cruises, teacher-training workshops, mini-grants to incorporate microbial oceanography-related content and activities into their classroom and, most recently, C- MORE science kits. C-MORE science kits provide hands-on classroom, field, and laboratory activities related to microbial oceanography for K-12 students. Each kit comes with complete materials and instructions, and is available free of charge to Hawaii's public school teachers. Several kits are available nationwide. C-MORE science kits cover a range of topics and technologies and are targeted at various grade levels. Here is a sampling of some available kits: 1) Marine Murder Mystery: The Case of the Missing Zooxanthellae. Students learn about the effect of climate change and other environmental threats on coral reef destruction through a murder-mystery experience. Participants also learn how to use DNA to identify a suspect. Grades levels: 3-8. 2) Statistical sampling. Students learn basic statistics through an exercise in random sampling, with applications to microbial oceanography. The laptops provided with this kit enable students to enter, analyze, and graph their data using EXCEL. Grades levels: 6-12. 3) Chlorophyll Lab. A research-quality fluorometer is used to measure the chlorophyll content in marine and freshwater systems. This enables students to compare biomass concentrations in samples collected from various locations. Grades levels: 9-12. 4) Conductivity-Temperature-Depth (CTD). Students predict how certain variables (e.g., temperature, pressure, chlorophyll, oxygen) vary with depth. A CTD, attached to a laptop computer, is deployed into deep water

    2017-01-01

    Full Text Available The study of history is becoming increasingly less interesting to students, despite the fact that the history teaching process has been continuously modernized during recent years. It is an observation which can be perceived even if we don`t make an elaborated research in the field. Some empirical data show us that students in secondary and High Schools are less interested in studying History than in studying Geography or other social sciences. The number of students who are determined to study History in universities has significantly dropped in recent years [1]. Of course, there are multiple causes and the factors behind this change are numerous and varied. In this paper we handle only some changes in teaching History in High Schools, as they are designed in History Curricula and in History textbooks. Therefore during the first sequence of this paper we shall analyze the History Curricula for High School, 11th and 12th grades, regarding their finalities (competencies, some relevant contents and the recommended pedagogical approaches about the teaching methods and the auxiliary material. In the second part of the paper we propose some teaching activities through which students would practice the specific competencies from their Curriculum for History. We aim at presenting attractive teaching material and learning methods and applying the methodological recommendations from the High school Curricula for History, 11th and 12th grades.

    2005-01-01

    Background and purpose: In vitro studies have suggested that 9-nitro-20(s)-Camptothecin (9NC/Orathecin/Rubitecan) can enhance the effects of radiation. We conducted a phase I study to assess the toxicity and determine the maximum tolerated dose of 9NC when combined with radiation in patients with locally advanced adenocarcinoma of the pancreas. Patients and methods: Eleven patients with locally advanced adenocarcinoma of the pancreas received 9NC, orally during radiation. Radiation therapy consisted of 45 Gy in 25 fractions given over 5 weeks. The starting dose of 9NC was 1 mg/m 2 /day. Results: Eight patients received 9NC at a dose of 1 mg/m 2 /day and three patients received a dose of 1.25 mg/m 2 /day. Dose-limiting toxicity (DLT) was defined as ≥grade 3 non-hematologic toxicity and ≥grade 4 hematologic toxicity. Dose-limiting toxicity of grade 3 nausea/vomiting developed in one patient at the first dose level. At dose level 2, two of three patients developed DLT. Both developed grade 3 nausea, fatigue, and anorexia. Additionally, one of these patients had grade 3 dehydration and the other had grade 4 leukopenia, grade 3 vomiting, and grade 3 weakness. Conclusions: 9NC, 1 mg/m 2 /day, can be given concurrently with radiation with acceptable toxicity

    2005-01-01

    Background and purpose: To report local control and follow up outcome data of high precision conformal radiotherapy in childhood brain tumours. Materials and methods: Between December 1999 and December 2002, 26 children (17 boys and 9 girls, median age 11.5 years) with incompletely excised or recurrent benign and low-grade brain tumours [13 craniopharyngiomas, 11 low-grade gliomas (LGG) and 2 others] were treated with three-dimensional (3D) conformal radiotherapy (CRT) (12 patients) and stereotactic conformal radiotherapy (SCRT) (14 patients). Gross tumour volume (GTV) included neuro-imaging based visible tumour and/or resected tumour bed. Clinical target volume (CTV) consisted of GTV + 5 mm margin and planning target volume (PTV) consisted of additional 5 mm margin for CRT and 2 mm for SCRT. Treatment was delivered with 3-9 conformal fixed fields to a median dose of 54 Gy/30 fractions. Results: The actuarial 2 and 3 year disease free and overall survival was 96 and 100%, respectively (median follow up: 25 months, range 12-47 months). Radiological follow up available in 25 patients revealed complete response in 1, partial regression in 10, stable disease in 13 and progression in 1 patient (within the CTV). One patient with craniopharyngioma on a routine imaging revealed a mild asymptomatic cyst enlargement, which resolved with conservative management. A patient with chiasmatic glioma developed cystic degeneration and hydrocephalus 9 months after SCRT requiring cyst drainage and placement of a ventriculoperitoneal shunt. Conclusion: High-precision conformal techniques delivering irradiation to a computer generated target volume employing 7-10 mm 3D margins beyond the visible tumour and/or resected tumour bed appear to be safe in children with incompletely resected or recurrent benign and low-grade brain tumours, based on these data

    2013-06-01

    Full Text Available Purpose: To evaluate the risk of prostate cancer (PCa on a third prostate biopsy in a group of patients with two consecutive diagnoses of high grade intraepithelial neoplasia (HGPIN. Materials and methods: From November 2004 to December 2007, patients referred to our clinic with a PSA ! 4 ng/ml or an abnormal digital rectal examination (DRE were scheduled for trans-rectal ultrasound (TRUS guided 12-core prostate biopsy. Patients with HGPIN underwent a second prostate biopsy, and if the results of such procedure yielded a second diagnosis of HGPIN, we proposed a third 12-core needle biopsy regardless of PSA value. Crude and adjusted logistic regressions were used to assess predictors of PCa on the third biopsy. Results: A total of 650 patients underwent 12 cores transrectal ultrasound prostatic biopsy in the study period. Of 147 (22% men with a diagnosis of HGPIN, 117 underwent a second prostatic biopsy after six months and 43 a third biopsy after other six months. After the third biopsy, 19 patients (34% still showed HGPIN, 15 (35% were diagnosed with PCa and 9 (21% presented with chronic prostatitis. Widespread HGPIN on a second biopsy was significantly associated with PCa on further biopsy (!2 = 4.04, p = 0.04. Moreover, the presence of widespread HGPIN significantly predicted the risk of PCa on crude and adjusted logistic regressions. Conclusions: Widespread HGPIN on second biopsy is associated with the presence of PCa on a third biopsy. Nonetheless, the relationship between HGPIN and PCa remains complex and further studies are needed to confirm our findings.

  9. Is the Grading of Liver Injuries a Useful Clinical Tool in the Initial Management of Blunt Trauma Patients?

    Helling, Thomas S; Ward, Michael R; Balon, Jennifer

    2009-04-01

    Computed tomography (CT) has become the preferred method for evaluation of the abdomen for victims of blunt trauma. Grading of liver injuries, primarily by CT, has been advocated as a measure of severity and, by implication, the likelihood for intervention or complications. We have sought to determine if grading of liver injuries, as a clinical tool, affects immediate or extended management of patients. We have retrospectively reviewed all patients sustaining blunt liver injuries as diagnosed by CT over a five-year period at a Level I trauma center to determine if grading of injury influenced management. The AAST organ scaling system was utilized (major grade 4-5, minor grade 1-3), as well as the ISS, AIS, mortality, morbidity, and treatment. There were 133 patients available for review. The patients were grouped into major (n = 20) and minor (n = 113) liver injuries and operative (n = 12) and nonoperative (n = 121) management. Major liver injuries had a higher ISS (39 + 13 vs. 27 + 15, p = 0.001) and were more likely to require operative intervention (5/20 vs. 7/113, p = 0.02). Mortality in this group was not different (major vs. minor), and there were no differences in the incidence of complications. Twelve patients (9%) required operation, all for hemodynamic instability, all within 24 h, and 11/12 within 6 h. At operation 8/12 patients had other sources of bleeding beside the liver injury, and 7/12 had minor hepatic injuries. The operative patients had higher ISS and AIS scores (head/neck, chest, abdomen, extremities) than those managed nonoperatively. More patients died in the operative group (6/12 vs. 8/121, p = 0.0003). There were more pulmonary (6/12 vs. 16/121, p = 0.005), cardiovascular (6/12 vs. 19/121, p = 0.01), and infectious (5/12 vs. 20/121, p = 0.049) complications in the operative group. There were 14 deaths overall; 13/14 were due to traumatic brain injury, and 8/14 required urgent operation for hemorrhage. In conclusion, grading of liver

    The consumption of alcohol mixed with energy drinks (AmED) is a risky drinking behavior, most commonly studied using college samples. We know little about rates of AmED use and its associations with other risk behaviors, including unsafe driving, among high school students. This study examined the prevalence and correlates of AmED use among high school seniors in the United States. Nationally representative analytic samples included 6,498 12th-grade students who completed Monitoring the Future surveys in 2012 and 2013. Focal measures included AmED use, sociodemographic characteristics, academic and social factors, other substance use, and unsafe driving (i.e., tickets/warnings and accidents) after alcohol consumption. Approximately one in four students (24.8%) reported AmED use during the past 12 months. Rates of AmED use were highest among males and white students. Using multivariable logistic regression models controlling for sociodemographic characteristics, results indicate that students who cut class, spent more evenings out for fun and recreation, and reported binge drinking, marijuana use, and illicit drug use had a greater likelihood of AmED use. AmED use was also associated with greater odds of alcohol-related unsafe driving, even after controlling for sociodemographic, academic, and social factors and other substance use. AmED use among 12th-grade students is common and associated with certain sociodemographic, academic, social, and substance use factors. AmED use is also related to alcohol-related unsafe driving, which is a serious public health concern. Copyright © 2015 Society for Adolescent Health and Medicine. Published by Elsevier Inc.

  12. Investigations on diffusion-controlled transformations in creep resistant steels and graded cemented carbides

    Prat Borquez, Orlando

    2011-01-01

    The objective of this work was to simulate diffusion-controlled transformations on engineering alloys designed by the author and his colleagues. The main challenge of the work is to adapt the existing DICTRA models to the experimental processing and working conditions investigated, as well as to find the adequate boundary conditions for the description of the diffusion-controlled transformations governing the microstructure formation and evolution, in order to obtain reliable simulation results. The simulations were compared with experimental results of the microstructure evolution by scanning electron microscopy and scanning transmission electron microscopy (STEM). Two groups of materials were investigated. The first group was 9-12% Cr heat resistant alloys. These alloys are particularly interesting because the microstructure evolves during working conditions. Different compositions were designed in order to form different kinds and amounts of precipitates. For the designed 9-12% Cr creep steels the coarsening of MX and M 23 C 6 particles was modeled by applying the coarsening model implemented in DICTRA. The cell method of DICTRA was applied to investigate the kinetics of the Laves phase growth on 9-12% Cr alloys. The particular objectives of these investigations were: a) to determine the coarsening rate of precipitates, b) to investigate the influence of alloying element on the growth rate of the Laves phase, c) to determine the influence of the M 23 C 6 formation on the growth kinetics of the Laves phase, d) to determine the growth mechanism at the interface of the Laves phase (i.e. up-hill diffusion), e) to investigate the effect of the cell size on the simulation kinetics of Laves phase. The second group of materials was cemented carbides. They are used as cutting tools or wear parts in the automotive, aircraft and mining industry among others. The wear performance of cemented carbides (hardmetals and cermets) can be largely improved by applying wear

    Polyamide 12 (PA 12) is a high performance polymer with outstanding mechanical properties and excellent chemical stability. It is the preferred material in many demanding applications, e. g. in the automotive industry for fuel lines of passenger cars or for air brake tubing's in trucks. In recent years PA 12 pipes underwent an approval process for the use in high-pressure gas distribution and offshore oil explorations. Also the applications lining and rehabilitation of pipes are under investigation. Especially the swelling behavior and the outstanding resistance to oil and other petrochemicals make VESTAMID{sup TM} the material of choice for rehabilitation and lining applications. The authors will give an introduction to the excellent technical performance of PA 12. The very high melt viscosity and stiffness of the newly developed VESTAMID{sup TM} grades enables new applications of PA 12 in oil and gas applications which will be discussed in this paper.

    The Accordion severity grading system is a novel system to score the severity of postoperative complications in a standardized fashion. This study aims to demonstrate the validity of the Accordion system in colorectal surgery by correlating severity grades with short-term outcomes after right colectomy for colon cancer. This is a retrospective cohort review of patients who underwent right colectomy for cancer between January 1, 2002, and January 31, 2007, at a single tertiary care referral center. Complications were categorized according to the Accordion severity grading system: grades 1 (mild), 2 (moderate), 3-5 (severe), and 6 (death). Outcome measures were hospital stay, 30-d readmission rate and 1-y survival. Correlation between Accordion grades and outcome measures is reflected by Spearman rho (ρ). One-year survival was obtained per Kaplan-Meier method and compared by logrank test for trend. Significance was set at P ≤ 0.05. Overall, 235 patients underwent right colectomy for cancer of which 122 (51.9%) had complications. In total, 52 (43%) had an Accordion grade 1 complication; 44 (36%) grade 2; four (3%) grade 3; 11 (9%) grade 4; seven (6%) grade 5; and four (3%) grade 6. There was significant correlation between Accordion grades and hospital stay (ρ = 0.495, P trend in 1-y survival as complication severity by Accordion grade increased (P = 0.02). The Accordion grading system is a useful tool to estimate short-term outcomes after right colectomy for cancer. High-grade Accordion complications are associated with longer hospital stay and increased risk of readmission and mortality. Published by Elsevier Inc.

  20. Measurement of MMP-9 and -12 degraded elastin (ELM) provides unique information on lung tissue degradation

    Background Elastin is an essential component of selected connective tissues that provides a unique physiological elasticity. Elastin may be considered a signature protein of lungs where matrix metalloprotease (MMP) -9-and -12, may be considered the signature proteases of the macrophages, which in part are responsible for tissue damage during disease progression. Thus, we hypothesized that a MMP-9/-12 generated fragment of elastin may be a relevant biochemical maker for lung diseases. Methods Elastin fragments were identified by mass-spectrometry and one sequence, generated by MMP-9 and -12 (ELN-441), was selected for monoclonal antibody generation and used in the development of an ELISA. Soluble and insoluble elastin from lung was cleaved in vitro and the time-dependent release of fragments was assessed in the ELN-441 assay. The release of ELN-441 in human serum from patients with chronic obstructive pulmonary disease (COPD) (n = 10) and idiopathic pulmonary fibrosis (IPF) (n = 29) were compared to healthy matched controls (n = 11). Results The sequence ELN-441 was exclusively generated by MMP-9 and -12 and was time-dependently released from soluble lung elastin. ELN-441 levels were 287% higher in patients diagnosed with COPD (p elastin. This fragment was elevated in serum from patients with the lung diseases IPF and COPD, however these data needs to be validated in larger clinical settings. PMID:22818364

    Brown, Norman Merrill

    1998-09-01

    Historically, researchers have reported an achievement difference between females and males on standardized science tests. These differences have been reported to be based upon science knowledge, abstract reasoning skills, mathematical abilities, and cultural and social phenomena. This research was designed to determine how mastery of specific science content from public school curricula might be evaluated with performance-based assessment models, without producing gender achievement differences. The assessment instruments used were Harcourt Brace Educational Measurement's GOALSsp°ler: A Performance-Based Measure of Achievement and the performance-based portion of the Stanford Achievement Testspcopyright, Ninth Edition. The identified independent variables were test, gender, ethnicity, and grade level. A 2 x 2 x 6 x 12 (test x gender x ethnicity x grade) factorial experimental design was used to organize the data. A stratified random sample (N = 2400) was selected from a national pool of norming data: N = 1200 from the GOALSsp°ler group and N = 1200 from the SAT9spcopyright group. The ANOVA analysis yielded mixed results. The factors of test, gender, ethnicity by grade, gender by grade, and gender by grade by ethnicity failed to produce significant results (alpha = 0.05). The factors yielding significant results were ethnicity, grade, and ethnicity by grade. Therefore, no significant differences were found between female and male achievement on these performance-based assessments.

    Translational research plays a crucial role in bridging the gap between fundamental and clinical research. The importance of integrating research training into medical education has been emphasized. Predictive factors that help to identify the most motivated medical students to perform academic research are unknown. In a cross-sectional study on a representative sample of 315 medical students, residents and attending physicians, using a comprehensive structured questionnaire we assessed motivations and obstacles to perform academic research curricula (ie, research initiation fellowship, Master 1, Research Master 2, and PhD). Independent predictive factors associated with high "motivation score" (top quartile on motivation score ranging from 0 to 10) to enroll in academic research curricula were derived using multivariate logistic regression analysis. Independent predictors of high motivation score for performing Master 1 curriculum were: "considering that the integration of translational research in medical curriculum is essential" (OR, 3.79; 95% CI, 1.49-9.59; P = 0.005) and "knowledge of at least 2 research units within the university" (OR, 3.60; 95% CI, 2.01-6.47; P motivation score for performing Research Master 2 curriculum were: "attending physician" (OR, 4.60; 95% CI, 1.86-11.37; P = 0.001); "considering that the integration of translational research in medical curriculum is essential" (OR, 4.12; 95% CI, 1.51-11.23; P = 0.006); "knowledge of at least 2 research units within the university" (OR, 3.51; 95% CI, 1.91-6.46; P = 0.0001); and "male gender" (OR, 1.82; 95% CI, 1.02-3.25; P = 0.04). Independent predictors of high motivation score for performing PhD curriculum were: "considering that the integration of translational research in medical curriculum is essential" (OR, 5.94; 95% CI, 2.33-15.19; P = 0.0002) and "knowledge of at least 2 research units within the university" (OR, 2.63; 95% CI, 1.46-4.77; P = 0.001).

    This study investigated bullying among siblings in both traditional and cyber forms, and the associations of gender, grade, peer bullying perpetration, trait anger, and moral disengagement. The participants were 455 children in Grades 5 to 12 (262 girls and 177 boys with 16 unknown gender) who had a sibling. As the number of siblings who only bullied by technology was low, these associations were not able to be calculated. However, the findings showed that the percentage of sibling traditional bullying perpetration (31.6%) was higher than peer bullying perpetration (9.8%). Sibling bullies reported engaging in complex behaviors of perpetration and victimization in both the physical and in cyber settings, although the number was small. Gender, trait anger, moral disengagement, and bullying peers at school (but not grade) were all significantly associated with sibling traditional bullying perpetration. The implications of the findings are discussed for bullying intervention and prevention programs to understand childhood bullying in diverse contexts. © The Author(s) 2014.

    Entrustable professional activities (EPAs) were introduced as a principle for individualized physician assistant (PA) workplace curricula at the University of Applied Sciences (UAS) Utrecht in 2008. We studied how the focus on EPAs served the competency-based flexibility intention of the program. We analyzed data of those 119 students who enrolled in the program 2010 through 2013, and completed the program before April 2016. We analyzed the number of EPAs per student at start and end of the program, number changed during training and the reasons for change. Data of 101 students were suitable for evaluation. Excluded were 16 students ending the program prematurely and two with study delay. Mean number of EPAs per student at the start was 6.8 (range 4-12) and at the end 6.6 (range 3-13). On average 1.5 EPAs were altered (range 0-13). Reasons included extension of the EPA package during training (n = 10), lack of proficiency at planned moments of summative entrustment decisions (n = 9) and procedures not being suitable for PAs at closer look (n = 6). All changes resulted in a curriculum meeting the school's standards for graduation. The flexibility of the EPA concept enabled changes in the individualized curriculum of students, according to the intended competency-based nature of the educational program.

    Various martensitic 9-12 Cr steels are utilized currently in fossil fuel powered energy plants for their good elevated temperature properties such as creep strength, steam side oxidation resistance, fire side corrosion resistance, and thermal fatigue resistance. Need for further improvements on the properties of 9-12 Cr steels for higher temperature (>600oC) use is driven by the environmental concerns (i.e., improve efficiency to reduce emissions and fossil fuel consumption). In this paper, we will discuss the results of the research done to explore new subsitutional solute solution and precipitate hardening mechanisms for improved strength of 9-12 Cr martensitic steels. Stability of the phases present in the steels will be evaluated for various temperature and time exposures. A comparison of microstructural properties of the experimental steels and commercial steels will also be presented.

    The influence of a Ce surface treatment on oxidation behavior of a commercial (P91) and several experimental steels containing 9 to 12 weight percent Cr was examined at 650ºC in flowing dry and moist air. The oxidation behavior of all the alloys without the Ce modification was significantly degraded by the presence of moisture in the air during testing. For instance the weight gain for P91 was two orders of magnitude greater in moist air than in dry air. This was accompanied by a change in oxide scale from the formation of Cr-based scales in dry air to the formation of Fe-based scales in moist air. The Ce surface treatment was very effective in improving the oxidation resistance of the experimental steels in both moist and dry air. For instance, after exposure to moist air at 650ºC for 2000 hours, an experimental alloy with the cerium surface modification had a weight gain three orders of magnitude lower than the alloy without the Ce modification and two orders of magnitude lower than P91. The Ce surface treatment suppressed the formation of Fe-based scales and

    2001-12-01

    State standards are the basis upon which states and local schools build curricula. Usually taking the form of lists of what students are expected to learn at specified grades or clusters of grades, they influence statewide examinations, textbooks, teacher education and credentialing, and other areas in which states typically exercise control over local curriculum development. State science standards vary very widely in overall quality.1,2 This is especially true in their treatment of evolution, both in the life sciences and to a somewhat lesser extent in geology and astronomy. Not surprisingly, a detailed evaluation of the treatment of evolution in state science standards3 has evoked considerably more public interest than the preceding studies of overall quality. We here consider the following questions: What constitutes a good treatment of evolution in science standards and how does one evaluate the standards? Which states have done well, and which less well? What nonscientific influences have been brought to bear on standards, for what reasons, and by whom? What strategies have been used to obscure or distort the role of evolution as the central organizing principle of the historical sciences? What are the effects of such distortions on students' overall understanding of science? What can the scientific community do to assure the publication of good science standards and to counteract attacks on good science teaching? 1. Lerner, L.

    Approaching patient care from a holistic perspective, incorporating not only the patient's medical and dental history but also psychosocial history, improves patient outcomes. Practitioners should be trained to provide this style of care through inclusive education, including training working on interprofessional teams. A component of this education must incorporate social determinants of health into the treatment plan. Social determinants of health include income, race/ethnicity, education level, work opportunities, living conditions, and access to health care. Education regarding social determinants of health should be woven throughout dental curricula, including hands-on application opportunities. This education must extend to patient care situations rather than be limited to didactic settings. This article explains the need to incorporate social determinants of health into dental education and illustrates how social determinants education is being addressed in two U.S. dental schools' curricula, including how to weave social determinants of health into interprofessional education. These descriptions may serve as a model for curricular innovation and faculty development across the dental education community.

    2005-02-01

    Medium Cr steels have been used in fossil fired power plants for many years because of their excellent high temperature stability and mechanical properties. As the desire to increase the efficiency of power plants continues, the operating temperature (>650C) continues to go up. Currently available low and medium Cr containing steels will not withstand the new operating temperature and must be reassessed in terms of their solid-solution and precipitation strengthening schemes. Three medium Cr steels were developed to investigate high temperature alloy strengthening strategies: 0.08C-(9-12)Cr-1.2Ni-0.7Mo-3.0Cu-3.0Co-0.5Ti. The microstructure of the alloy will be described in the as-cast and thermo-mechanically worked states. In addition, the effect on microstructure from long-term high temperature exposure will also be discussed. Finally, the overall stability of these steels will be compared against currently available power plant steels.

  16. The role of visualisation in data handling in Grade 9 within a problem-centred context

    2009-09-01

    Full Text Available In the recent past, data handling has been neglected at secondary school level, perhaps partially due to the strong emphasis on developing arithmetic, algebra and geometry. For the first time, the South African curriculum includes substantial amounts of data handling at all grade levels. The introduction of more data handling in the secondary school curriculum in South Africa and the prevalence of many problems in the teaching of probability and statistics argues for a serious reconsideration of the way it is taught to the pupils. Currently this concern has been the focus of a call for reform in mathematics education by a body like the National Council of Teachers of Mathematics (NCTM at all levels of schooling (NCTM, 1989; 2000. The importance of visualisation in mathematics, at all levels of mathematical problem solving is well documented in the literature (Bishop, 1989; Maher & Alston, 1989; Moses, 1982; Wheatley, 1991 but almost nothing was done to appreciate visualisation in the learning of data handling. The paper therefore provides a qualitative examination from a Masters dissertation (Makina, 2005 of the role of visualisation in the learning of data handling. This is done through examining the thought processes involved by Grade 9 learners during visualisation while solving data handling tasks. Several roles of visualisation were identified and most were found to improve the critical and creative thinking of pupils during their learning of data handling. The results show that learners are likely to improve their performance in data handling if the awareness of the need to use visualisation creatively as a tool for understanding are highlighted.

    The purpose of this study was to assess student's performance in the interpretation of images before and after training in radiology, by comparing two groups, 6th-year and 3rd-year students, from two different medical curricula. Students participated in an anonymous evaluation consisting of the interpretation of 12 radiological images accompanied with the salient history and clinical data by answering 60 open-ended questions about technique, anatomy, semiology, and clinics. The number of correct, incorrect and blank responses of each group was used to compare pre- and post-training results. Unpaired two-sample t-test was used to evaluate differences between groups. A significant increase in correct responses was found in both groups after training. The comparison between both groups did not show differences for incorrect answers of the whole test and correct answers about anatomy in the pre-training evaluation. The percentage of correct answers to the median question improved from 15.5% to 53.3% for 6th-year students and from 8.3% to 41.1% for 3rd-year students. The post-training evaluation showed a significant increase of correct answers of 6th-year students with respect to 3rd-year students (mean ± standard deviation 53.6 ± 31.3% and 38.7 ± 29.9% respectively), mainly due to differences in technical and clinical questions. This study provides objective and quantitative evidence of pre- and post-training student skills in image interpretation. The similarities found in the previous level of knowledge and skills of both groups emphasizes the suitable change of the first-time training in radiology, from the 6th to the 3rd year course in medical curricula.

    Pregraduate medical curricula are currently undergoing a reform process that is moving away from a traditional discipline-related structure and towards problem-based integrated forms of teaching. Imaging sciences, with their inherently technical advances, are specifically influenced by the effects of paradigm shifts in medical education. The teaching of diagnostic radiology should be based on the definition of three core competencies: in vivo visualization of normal and abnormal morphology and function, diagnostic reasoning, and interventional treatment. On the basis of these goals, adequate teaching methods and e-learning tools should be implemented by focusing on case-based teaching. Teaching materials used in the fields of normal anatomy, pathology, and clinical diagnosis may help diagnostic radiology to play a central role in modern pregraduate curricula. (orig.)

  5. Unexpected attitudinal growth in a course combining reformed curricula

    Directory of Open Access Journals (Sweden)

    Michael M. Hull

    2016-01-01

    Full Text Available In this paper, we show data from the Colorado Learning Attitudes about Science Survey that suggests that Georgetown physics majors become increasingly expert in their attitudes towards physics learning and knowing after taking a course that combines two reformed curricula, Matter and Interactions (M&I and Tutorials in Introductory Physics (TIPs. This occurs even though the two curricula do not send a consistent epistemological message to students. We analyze interview video data of two of these students to illustrate examples of this growth. We examine video data of one of these students in a tutorial session to describe a possible mechanism that may have contributed to the growth. Finally, we compare this qualitative video data with quantitative data from the newly developed Perceptions of Physics Classes survey and discuss aggregate responses to this survey in considering the ways in which other students developed more expertlike attitudes in this course. We conclude that the attitudinal growth observed cannot be explained simply “as the result of” either M&I or of TIPs but rather find the most plausible explanation to be that the growth is an emergent phenomena produced by M&I and TIPs working together in concert with other factors.

  6. Identification of food-grade subtilisins as gluten-degrading enzymes to treat celiac disease

    2016-01-01

    Gluten are proline- and glutamine-rich proteins present in wheat, barley, and rye and contain the immunogenic sequences that drive celiac disease (CD). Rothia mucilaginosa, an oral microbial colonizer, can cleave these gluten epitopes. The aim was to isolate and identify the enzymes and evaluate their potential as novel enzyme therapeutics for CD. The membrane-associated R. mucilaginosa proteins were extracted and separated by DEAE chromatography. Enzyme activities were monitored with paranitroanilide-derivatized and fluorescence resonance energy transfer (FRET) peptide substrates, and by gliadin zymography. Epitope elimination was determined in R5 and G12 ELISAs. The gliadin-degrading Rothia enzymes were identified by LC-ESI-MS/MS as hypothetical proteins ROTMU0001_0241 (C6R5V9_9MICC), ROTMU0001_0243 (C6R5W1_9MICC), and ROTMU0001_240 (C6R5V8_9MICC). A search with the Basic Local Alignment Search Tool revealed that these are subtilisin-like serine proteases belonging to the peptidase S8 family. Alignment of the major Rothia subtilisins indicated that all contain the catalytic triad with Asp (D), His (H), and Ser (S) in the D-H-S order. They cleaved succinyl-Ala-Ala-Pro-Phe-paranitroanilide, a substrate for subtilisin with Pro in the P2 position, as in Tyr-Pro-Gln and Leu-Pro-Tyr in gluten, which are also cleaved. Consistently, FRET substrates of gliadin immunogenic epitopes comprising Xaa-Pro-Xaa motives were rapidly hydrolyzed. The Rothia subtilisins and two subtilisins from Bacillus licheniformis, subtilisin A and the food-grade Nattokinase, efficiently degraded the immunogenic gliadin-derived 33-mer peptide and the immunodominant epitopes recognized by the R5 and G12 antibodies. This study identified Rothia and food-grade Bacillus subtilisins as promising new candidates for enzyme therapeutics in CD. PMID:27469368

    Full Text Available This study was conducted to determine the expression of matrix metalloproteinase-9 (MMP-9 and tissue inhibitor of metalloproteinase-1 (TIMP-1 in a time-dependent manner and the effect of extracellular-signal-regulated kinases-1/2 (ERK1/2 inhibition on the expressions of MMP-9, TIMP-1, and inflammatory biomarkers in the retinas of diabetic rats. The expression of MMP-9 was quantified by zymography, and the mRNA level of MMP-9 and TIMP-1 was quantified by RT-PCR. The expression of inducible nitric oxide synthase (iNOS, interleukin-6 (IL-6, and tumor necrosis factor-alpha (TNF-α was examined by Western blot analysis. MMP-9 expression was significantly higher in diabetic rat retinas compared to controls at all time points.TIMP-1 expression was nonsignificantly upregulated at 1week of diabetes and was significantly downregulated at 4 and 12 weeks of diabetes. Intravitreal administration of the ERK1/2 inhibitor U0126 prior to induction of diabetes decreased ERK1/2 activation, attenuated diabetes-induced upregulation of MMP-9, iNOS, IL-6, and TNF-α and upregulated TIMP-1 expression. In MMP-9 knockout mice, diabetes had no effect on retinal iNOS expression and its level remained unchanged. These data provide evidence that ERK1/2 signaling pathway is involved in MMP-9, iNOS, IL-6, and TNF-α induction in diabetic retinas and suggest that ERK1/2 can be a novel therapeutic target in diabetic retinopathy.

    Suicidal behavior among adolescents is not a well-explored public health problem. Health policy decision-making on suicidal behavior needs reliable information on the prevalence of suicidal ideation (SI) and its associated risk factors to produce health promotion and prevention programs. The Global School Health Survey is a self-administered survey done on a random probabilistic sample among students of the 7th, 8th, and 9th grades in the Lara State, Venezuela, school period 2003 to 2004. Point prevalence of SI and associated factors were included and the odds (OR) of having SI was calculated given selected factors. Two-thousand seventy (2070) respondents, of which 13.5 % reported having SI in the last 12 months, and in females more than males (14.6% vs. 11.7%). The OR for SI, according to an associated risk factor, were among (a) females: age > or = 14 years (2.2), worries (3.42), loneliness (8.8), ever had sexual intercourse (5.58), alcohol (8.43) and (b) males: having only one or non close friends (3.69), alcohol (12.36), ever had sexual intercourse (2.73). Behavioral risk factors are relatively new in the field of surveillance systems; therefore, results on SI should be cautiously taken into consideration and a wide discussion should be encouraged as we learn how to best use the results for health promotion and disease prevention.

    Medical schools, although the gatekeepers of much biomedical education and research, rarely engage formally with K-12 educators to influence curriculum content or professional development. This segregation of content experts from teachers creates a knowledge gap that limits inclusion of current biomedical science into high school curricula, affecting both public health literacy and the biomedical pipeline. The authors describe how, in 2009, scientists from Tufts Medical School and Boston public school teachers established a partnership of formal scholarly dialogue to create 11th- to 12th-grade high school curricula about critical health-related concepts, with the goal of increasing scientific literacy and influencing health-related decisions. The curricula are based on the great diseases (infectious diseases, neurological disorders, metabolic disease, and cancer). Unlike most health science curricular interventions that provide circumscribed activities, the curricula are comprehensive, each filling one full term of in-class learning and providing extensive real-time support for the teacher. In this article, the authors describe how they developed and implemented the infectious disease curriculum, and its impacts. The high school teachers and students showed robust gains in content knowledge and critical thinking skills, whereas the Tufts scientists increased their pedagogical knowledge and appreciation for health-related science communication. The results show how formal interactions between medical schools and K-12 educators can be mutually beneficial.

  13. Experiencing the Implementation of New Inquiry Science Curricula

    Science.gov (United States)

    Ower, Peter S.

    Using a phenomenological methodology, a cohort of four experienced science teachers was interviewed about their experience transitioning from traditional, teacher and fact-centered science curricula to inquiry-based curricula. Each teacher participated in two interviews that focused on their teaching backgrounds, their experience teaching the prior traditional curriculum, and their experience teaching the new inquiry-based curriculum. The findings are presented as a narrative of each teachers' experience with the new curriculum implementation. Analyzing the data revealed four key themes. 1) The teachers felt trapped by the old curriculum as it did not align with their positive views of teaching science through inquiry. 2) The teachers found a way to fit their beliefs and values into the old and new curriculum. This required changes to the curriculum. 3) The teachers attempted to make the science curriculum as meaningful as possible for their students. 4) The teachers experienced a balancing act between their beliefs and values and the various aspects of the curriculum. The revealed essence of the curriculum transition is one of freedom and reconciliation of their beliefs. The teachers experienced the implementation of the new curriculum as a way to ensure their values and beliefs of science education were embedded therein. They treated the new curriculum as a malleable structure to impart their grander ideas of science education (e.g. providing important skills for future careers, creating a sense of wonder, future problem solving) to the students. Their changes were aligned with the philosophy of the curriculum kits they were implementing. Thus, the fidelity of the curriculum's philosophy was not at risk even though the curriculum kits were not taught as written. This study showed that phenomenological methods are able to reveal the relationship between a teacher's prior experiences, values and beliefs and their current instructional philosophy in science

    Preparation for responding to emergency events that does not warrant outside help beyond the local community resources or responding to disaster events that is beyond the capabilities of the local community both require first responders and healthcare professionals to have interdisciplinary skills needed to function as a team for saving lives. To date, there is no core emergency preparedness and disaster planning competencies that have been standardized at all levels across the various allied health curricula disciplines. To identify if emergency preparedness and disaster training content are currently being taught in allied health program courses, to identify possible gaps within allied health curricula, and to explore the perceptions of allied health college educators for implementing emergency preparedness and disaster training core competencies into their existing curricula, if not already included. A quantitative Internet-based survey was conducted in 2013. Convenient sample. Fifty-one allied health college educators completed the survey. Descriptive statistics indicated that the majority of allied health college instructors do not currently teach emergency preparedness and disaster training core competency content within their current allied health discipline; however, their perceived level of importance for inclusion of the competencies was high. The results of this study supported the need for developing and establishing a basic national set of standardized core emergency preparedness and disaster planning competencies at all levels across various allied health curricula disciplines to ensure victims receive the best patient care and have the best possible chance of survival.

  17. Science teacher orientations and PCK across science topics in grade 9 earth science

    Science.gov (United States)

    Campbell, Todd; Melville, Wayne; Goodwin, Dawne

    2017-07-01

    While the literature is replete with studies examining teacher knowledge and pedagogical content knowledge (PCK), few studies have investigated how science teacher orientations (STOs) shape classroom instruction. Therefore, this research explores the interplay between a STOs and the topic specificity of PCK across two science topics within a grade 9 earth science course. Through interviews and observations of one teacher's classroom across two sequentially taught, this research contests the notion that teachers hold a single way of conceptualising science teaching and learning. In this, we consider if multiple ontologies can provide potential explanatory power for characterising instructional enactments. In earlier work with the teacher in this study, using generic interview prompts and general discussions about science teaching and learning, we accepted the existence of a unitary STO and its promise of consistent reformed instruction in the classroom. However, upon close examination of instruction focused on different science topics, evidence was found to demonstrate the explanatory power of multiple ontologies for shaping characteristically different epistemological constructions across science topics. This research points to the need for care in generalising about teacher practice, as it reveals that a teacher's practice, and orientation, can vary, dependent on the context and science topics taught.

  18. Controversy in the classroom: How eighth-grade and undergraduate students reason about tradeoffs of genetically modified food

    Science.gov (United States)

    Seethaler, Sherry Lynn

    Current issues in science provide a rich context for learning because they can involve complex tradeoffs that cut across traditional disciplinary boundaries. Despite this potential benefit, and the need for citizens to make decisions about such issues, science controversy remains rare in the classroom. Consequently, there is much unknown about how students make sense of complex, multidisciplinary science. This research examined eighth-grade (n = 190) and undergraduate (n = 9) students' reasoning about tradeoffs in the genetically modified food controversy (main study). To extend the findings from the main study, undergraduate students' reasoning was followed as they learned about ten additional science controversies (extension). The studies took place in the context of curricula designed on the basis of the Scaffolded Knowledge Integration Framework, which posits a set of design principles that help students form a rich, integrated network of ideas about a topic. Two new methodologies were developed for this work. The Embedded Perspective of Science Controversy was used to study students' integration of content in their written arguments (main study) and oral and written questions (extension). The Perspective views science controversy as a set of nested levels, where tradeoffs are one of the levels, but connecting to other levels (underlying scientific details, bigger picture context, etc.) is important for the weighing of tradeoffs. A scheme based on Toulmin's (1958) work on argumentation provided a way of comparing the structure of students' arguments. As indicated by pre and post test scores, the curriculum helped both eighth-grade students (t = 11.7, p genetically modified food. In their final papers, both eighth-grade and undergraduate students presented evidence for and against their positions, in contrast with prior literature showing individuals have difficulty coming up with evidence against their positions. The students were also moving across the levels

    Full Text Available Abstract This article problematizes the lack of plurality of knowledges in International Relations theory curricula. The increase in knowledges and scholarship from the South has not seemingly filtered into International Relations theory curricula significantly. Thus Western knowledges still dominates the narrative. It investigates how knowledge structures inherent in the discipline coupled with Western centric ontology and epistemology function to exclude or marginalize knowledge that does not conform to specific criteria. I demonstrate how the third year IR theory curriculum at Wits University, has engaged with discipline’s knowledge structures as well as its ontology and epistemology to develop a knowledge plural curricula.

    2013-01-01

    Patients with vestibular schwannomas (VS) are either assigned to watchful waiting, microsurgical resection, or radiosurgery. Decision making on how to proceed is based on parameters such as age, tumor growth, loss of hearing, and the tumor's Koos grading. In order to correlate Koos grading with tumor volume, patient records of 235 patients with VS who underwent Gamma Knife radiosurgery (GKRS) were retrospectively reviewed. From 1994 to 2009, 235 consecutive patients underwent GKRS for sporadic VS at the Zurich Gamma Knife Center. Median follow up was 62.8 ± 33.0 months. Of the 235 tumors, 32 (13.6 %) were graded Koos I with a volume of 0.25 ± 0.3 cc; 71 (30.2 %) were graded Koos II with a volume of 0.57 ± 0.54 cc; 70 (29.8 %) were graded Koos III with a volume of 1.82 ± 1.88 cc; and 62 (26.4 %) were graded Koos IV with a volume of 4.17 ± 2.75 cc. Tumor progression was defined as a volume increase > 20 % at 2 years or later following GKRS. Overall tumor progression occurred in 21/235 (8.9 %) patients at 3.4 ± 0.9 years. Tumor progression did not differ statistically significantly in the various Koos grades: 1/32 (3.1 %) patients with VS Koos Grade I, 7/71 (9.8 %) patients with VS Koos Grade II, 6/70 (8.6 %) patients with VS Koos Grade III, and 7/62 (11.3 %) patients with VS Koos Grade IV. To our knowledge, this is the first work correlating the various Koos grades of VS to their respective tumor volumes. In our patients, tumor volumes of VS Koos Grade IV were limited because all of our patients were eligible for radiosurgery. In our series, the outcome following GKRS for patients with VS Koos Grade IV tumors did not differ from patients with VS Koos Grades I-III. We therefore suggest to limit Koos Grade IV VS to tumor volumes 6 cc that may not be eligible for radiosurgery.

    Full Text Available Difference, as cultural identity, appears as an urgent demand in the curricula for all school subjects. Therefore, this paper aims at identifying the treatment given to differences by some of the most relevant proposals in the physical education area. Three Brazilian works were analyzed for having influenced the dissemination of psychomotor (FREIRE, 1989, developmental (TANI et al., 1988 and critical-overcoming (SOARES et al., 1992 curricula. The results revealed a conservative perspective based (a on the assimilation of differences or (b on the humanistic appropriation supported by the belief of the equality principle disregarding issues such as ethnicity, genre or sexuality. The conclusion is that, in both cases, integrating the different cultural groups to the dominant culture is sought so that everybody can compete as equals in the modern capitalist society.

    Making palliative care accessible to all citizens who are in need of this type of care requires effective policies and education. Moreover, healthcare professionals have an ethical and legal responsibility to ensure quality palliative care. Nevertheless, palliative care has had traditionally a limited emphasis in healthcare professionals' undergraduate education. To study the current status of palliative care education in nursing undergraduate curricula and compare 2005 and 2015 findings. An online survey was sent to all state schools providing nursing undergraduate education in Portugal (N = 21). The survey assessed if and how palliative care was included in the curricula, and whether or not national and international recommendations for palliative care nursing education were followed. Further analysis included the content of available curricula/syllabi. A total of 19 schools completed the survey (90% of response rate). These institutions are geographically dispersed and representative of state nursing educational institutions in Portugal. In 2015, all participant schools integrated palliative care in their curricula; nine schools had palliative care as an independent curricular unit (an 800% increase compared to 2005). While in 2005, only 14 out of 23 (61%) schools included palliative care explicitly in their curricula; in 2015, all 19 participant schools did so. National and international recommendations were followed. The inclusion of palliative care within nursing undergraduate curricula strongly increased from 2005 to 2015. Further research is needed to understand the contribution of education in the access, care provision, quality and development of palliative care in this country. © The Author(s) 2016.

  6. Crevice corrosion and hydrogen embrittlement of grades-2 and -12 titanium under Canadian nuclear waste vault conditions

    Results on the corrosion of titanium grades 2 and 12 under the saline conditions anticipated in Canadian nuclear waste vaults are presented. The experimental approach included short-term electrochemical experiments to determine corrosion mechanisms, the susceptibility of titanium to crevice corrosion under a variety of conditions, and the extent of hydrogen uptake under controlled conditions; medium-term corrosion tests lasting a few weeks to a few months; and long-term immersion tests to provide rates for uniform corrosion, crevice corrosion, and hydrogen pickup. Results indicated that propagation, not initiation, is important in establishing susceptibility to crevice corrosion. Increasing the iron content of Ti-2 to 0.13 weight percent prevents crevice corrosion by causing repassivation. Crevice corrosion initiates on Ti-12, but repassivation is rapid. The supply of oxidant is essential to maintain crevice propagation. Hydrogen embrittlement is unlikely unless oxide film breakdown occurs. Film breakdown occurs under crevice conditions, and hydrogen pickup is to be expected. Film breakdown could occur if the strain or creep rate is fast enough to compete with repassivation reactions, a highly unlikely situation

    2016-07-15

    A strong foundational understanding of microbiology is crucial for the 21st century physician. Given recent major advances in medical microbiology, curricular changes will likely be needed. Before transforming curricula, we must first obtain a comprehensive understanding of contemporary medical student microbiology education. We disseminated a 38-question survey to microbiology course directors and curriculum deans at 142 US medical schools accredited by the Liason Committee on Medical Education. Survey questions focused on course leadership, curricular structure, course content, and educator perceptions about microbiology education locally and nationally. One hundred and four (73%) of 142 schools completed the survey. Ninety-four (90%) schools identified a course director. Of these, 48% were led by microbiologists alone, 23% co-led by a microbiologist and a clinician, 20% by a clinician alone, and 8% by a laboratory medicine physician with or without a co-director. At 55 (53%) schools, the curricula were organized in a single block or course and at 47 (45%) it was integrated into other curricula. Areas of emerging importance, such as antimicrobial stewardship, global health, infection control, and the microbiome, were addressed at 66%, 65%, 64%, and 47% of institutions, respectively. Respondents reported the following concerns: challenges integrating microbiology into other courses, reduced total teaching hours, and difficulty balancing basic and clinical science topics. Preclinical microbiology course directors report significant challenges in meeting the needs of changing curriculum structure and content. Enhanced local collaboration between microbiologists and clinicians, as well as national collaboration among relevant societies to design best practices and support research, may be strategies for future success. © The Author 2016.

    Ito, Tomohiko; Itakura, Tetsuro

    A 0.9-V 12-bit 40-MSPS pipeline ADC with I/Q amplifier sharing technique is presented for wireless receivers. To achieve high linearity even at 0.9-V supply, the clock signals to sampling switches are boosted over 0.9V in conversion stages. The clock-boosting circuit for lifting these clocks is shared between I-ch ADC and Q-ch ADC, reducing the area penalty. Low supply voltage narrows the available output range of the operational amplifier. A pseudo-differential (PD) amplifier with two-gain-stage common-mode feedback (CMFB) is proposed in views of its wide output range and power efficiency. This ADC is fabricated in 90-nm CMOS technology. At 40MS/s, the measured SNDR is 59.3dB and the corresponding effective number of bits (ENOB) is 9.6. Until Nyquist frequency, the ENOB is kept over 9.3. The ADC dissipates 17.3mW/ch, whose performances are suitable for ADCs for mobile wireless systems such as WLAN/WiMAX.

    2015-01-01

    Full Text Available Background: The treatment of high-grade developmental spondylolisthesis (HGDS is still challenging and controversial. In this study, we investigated the efficacy of the posterior reduction and monosegmental fusion assisted by intraoperative three-dimensional (3D navigation system in managing the HGDS. Methods: Thirteen consecutive HGDS patients were treated with posterior decompression, reduction and monosegmental fusion of L5/S1, assisted by intraoperative 3D navigation system. The clinical and radiographic outcomes were evaluated, with a minimum follow-up of 2 years. The differences between the pre- and post-operative measures were statistically analyzed using a two-tailed, paired t-test. Results: At most recent follow-up, 12 patients were pain-free. Only 1 patient had moderate pain. There were no permanent neurological complications or pseudarthrosis. The magnetic resonance imaging showed that there was no obvious disc degeneration in the adjacent segment. All radiographic parameters were improved. Mean slippage improved from 63.2% before surgery to 12.2% after surgery and 11.0% at latest follow-up. Lumbar lordosis changed from preoperative 34.9 ± 13.3° to postoperative 50.4 ± 9.9°, and 49.3 ± 7.8° at last follow-up. L5 incidence improved from 71.0 ± 11.3° to 54.0 ± 11.9° and did not change significantly at the last follow-up 53.1 ± 15.4°. While pelvic incidence remained unchanged, sacral slip significantly decreased from preoperative 32.7 ± 12.5° to postoperative 42.6 ± 9.8°and remained constant to the last follow-up 44.4 ± 6.9°. Pelvic tilt significantly decreased from 38.4 ± 12.5° to 30.9 ± 8.1° and remained unchanged at the last follow-up 28.1 ± 11.2°. Conclusions: Posterior reduction and monosegmental fusion of L5/S1 assisted by intraoperative 3D navigation are an effective technique for managing high-grade dysplastic spondylolisthesis. A complete reduction of local deformity and excellent correction of overall

    2011-12-01

    Today's youth have been tasked with the overwhelming job of addressing the world's climate future. The students who will become the scientists, policy makers, and citizens of tomorrow must gain a robust understanding of the causes and effects of climate change, as well as possible adaptation strategies. Currently, there are few high quality curricula available to teachers that address these topics in a developmentally appropriate manner. The NOAA-funded Ocean Sciences Sequence for Grades 6-8 aims to address this gap by providing teachers with scientifically accurate climate change curriculum that hits on some of the most salient points in climate science, while simultaneously developing students' science process skills. The Ocean Sciences Sequence for Grades 6-8 is developed through a collaboration between some of the nation's leading ocean and climate scientists and the Lawrence Hall of Science's highly qualified GEMS (Great Explorations in Math & Science) curriculum development team. Scientists are active partners throughout the whole development process, from initial brainstorming of key concepts and creating the conceptual storyline for the curriculum to final review of the content and activities. As with all GEMS Sequences, the Ocean Sciences Sequence for Grades 6-8 is designed to provide significant scientific and educational depth, systematic assessments and informational readings, and incorporate new learning technologies. The goal is to focus strategically and effectively on the core concepts within ocean and climate sciences that students need to understand. This curriculum is designed in accordance with the latest research from the learning sciences, and provides numerous opportunities for students to develop inquiry skills and abilities as they learn about the practice of science through hands-on activities. The Ocean Sciences Sequence for Grades 6-8 addresses in depth a significant number of national, state, and district standards and benchmarks. It
