  1. Comparison of Attitudes Toward Death Between University Students Who Receive Nursing Education and Who Receive Religious Education. (United States)

    Bakan, Ayse Berivan; Arli, Senay Karadag


    This study aims to compare attitudes toward death between university students who receive nursing education and who receive religious education. This study is cross-sectional in nature. It was conducted with the participation of 197 university students in a university located in the Eastern part of Turkey between June and August, 2017. Data were collected using the socio-demographic form and Turkish form of Death Attitudes Profile-Revised. Of all the students participating in the study, 52.8% received nursing education and 47.2% received religious education. It was found that majority of both groups had no education about death, or found the education they received insufficient. Besides, no significant differences were found between the students who received nursing education and who received religious education in terms of their attitudes toward death (p > 0.05). Results showed that students who received nursing education and who received religious education had similar attitudes toward death. In conclusion, the education given to students about the religious or health aspects of death in accordance with the curriculum seemed to have no effects on students' developing positive attitudes toward death.

  2. Training auscultatory skills: computer simulated heart sounds or additional bedside training? A randomized trial on third-year medical students (United States)


    Background The present study compares the value of additional use of computer simulated heart sounds, to conventional bedside auscultation training, on the cardiac auscultation skills of 3rd year medical students at Oslo University Medical School. Methods In addition to their usual curriculum courses, groups of seven students each were randomized to receive four hours of additional auscultation training either employing a computer simulator system or adding on more conventional bedside training. Cardiac auscultation skills were afterwards tested using live patients. Each student gave a written description of the auscultation findings in four selected patients, and was rewarded from 0-10 points for each patient. Differences between the two study groups were evaluated using student's t-test. Results At the auscultation test no significant difference in mean score was found between the students who had used additional computer based sound simulation compared to additional bedside training. Conclusions Students at an early stage of their cardiology training demonstrated equal performance of cardiac auscultation whether they had received an additional short auscultation course based on computer simulated training, or had had additional bedside training.

  4. Simulation Pedagogy With Nurse Practitioner Students: Impact of Receiving Immediate Individualized Faculty Feedback. (United States)

    Grossman, Sheila; Conelius, Jaclyn


    Family nurse practitioner (FNP) students must achieve basic competency in managing patients' primary care needs across the lifespan. Students in the FNP program have simulations integrated throughout their clinical theory courses to increase practice time with various patient cases. Students who received individualized faculty feedback immediately after self-evaluation of simulation performance showed statistically significantly increased knowledge (as evidenced by higher grades in course examinations and preceptor evaluations) than a control group of students who received feedback in a group class via a rubric grading guide 2-4 weeks after all students completed their individual simulations.

  5. Special Education Services Received by Students with Autism Spectrum Disorders from Preschool through High School. (United States)

    Wei, Xin; Wagner, Mary; Christiano, Elizabeth R A; Shattuck, Paul; Yu, Jennifer W


    Little is known about how special education services received by students with Autism Spectrum Disorders (ASDs) differ by age, disability severity, and demographic characteristics. Using three national datasets, the Pre-Elementary Education Longitudinal Study (PEELS), the Special Education Elementary Longitudinal Study (SEELS), and the National Longitudinal Transition Study-2 (NLTS2), this study examined the age trends in special education services received by students with ASDs from preschool through high school. Elementary-school students with ASDs had higher odds of receiving adaptive physical education, specialized computer software or hardware, and special transportation, but lower odds of receiving learning strategies/study skills support than their preschool peers. Secondary-school students had lower odds of receiving speech/language or occupational therapy and of having a behavior management program, but higher odds of receiving mental health or social work services than their elementary-school peers. Both disability severity and demographic characteristics were associated with differences in special education service receipt rates.

  6. "This is what you need to be learning": an analysis of messages received by first-year mathematics students during their transition to university (United States)

    Kouvela, Eirini; Hernandez-Martinez, Paul; Croft, Tony


    This paper explores the messages that first-year mathematics students receive in the context of their academic studies during their transition from school to university mathematics. Through observations of lectures and discussions with first-year mathematics undergraduates in an English university, we identified and analysed the messages that two of their lecturers transmitted to them during this transitional phase. The results suggest that strongly framed messages are more easily perceived by students and affect them during their transition. Additionally, messages that have been received in the school context continue to have control over students' thinking and on many occasions can impede adjustment to the new setting.

  14. Effects of additional team-based learning on students' clinical reasoning skills: a pilot study. (United States)

    Jost, Meike; Brüstle, Peter; Giesler, Marianne; Rijntjes, Michel; Brich, Jochen


    In the field of Neurology good clinical reasoning skills are essential for successful diagnosing and treatment. Team-based learning (TBL), an active learning and small group instructional strategy, is a promising method for fostering these skills. The aim of this pilot study was to examine the effects of a supplementary TBL-class on students' clinical decision-making skills. Fourth- and fifth-year medical students participated in this pilot study (static-group comparison design). The non-treatment group (n = 15) did not receive any additional training beyond regular teaching in the neurology course. The treatment group (n = 11) took part in a supplementary TBL-class optimized for teaching clinical reasoning in addition to the regular teaching in the neurology course. Clinical decision making skills were assessed using a key-feature problem examination. Factual and conceptual knowledge was assessed by a multiple-choice question examination. The TBL-group performed significantly better than the non-TBL-group (p = 0.026) in the key-feature problem examination. No significant differences between the results of the multiple-choice question examination of both groups were found. In this pilot study participants of a supplementary TBL-class significantly improved clinical decision-making skills, indicating that TBL may be an appropriate method for teaching clinical decision making in neurology. Further research is needed for replication in larger groups and other clinical fields.

  17. Misconception on Addition and Subtraction of Fraction at Primary School Students in Fifth-Grade (United States)

    Trivena, V.; Ningsih, A. R.; Jupri, A.


    This study aims to investigate the mastery concept of the student in mathematics learning especially in addition and subtraction of fraction at primary school level. By using qualitative research method, the data were collected from 23 grade five students (10-11-year-old). Instruments included a test, that is accompanied by Certainty Response Index (CRI) and interview with students and teacher. The result of the test has been obtained, then processed by analyzing the student’s answers for each item and then grouped by the CRI categories that combined with the results of the interview with students and teacher. The results showed that student’s mastery-concept on additional and subtraction dominated by category ‘misconception’. So, we can say that mastery-concept on addition and subtraction of fraction at fifth-grade students is still low. Finally, the impact can make most of primary student think that learning addition and subtraction of fraction in mathematics is difficult.

Each major module in these receivers is considered in detail. Design information is included as well as performance tradeoffs o

  1. The Responsible Inclusion of Students Receiving Special Education Services for Emotional Disturbance: Unraveling the Practice to Research Gap. (United States)

    McKenna, John William; Solis, Michael; Brigham, Frederick; Adamson, Reesha


    The majority of students receiving special education services for emotional disturbance (ED) receive a significant amount of instruction in general education classrooms, which emphasizes curriculums based on college and career readiness standards. In turn, those teachers who provide instruction to students with ED in inclusive settings are responsible for using evidence-based practices (EBPs) for those teaching situations in which they exist to meet free appropriate public education (FAPE) mandates. However, the identification of EBPs is a necessary pre-condition to eventual school adoption and teacher use of such practices. In this investigation, we completed a synthesis of syntheses to (a) determine the degree to which academic intervention research has focused on students with ED in general education classrooms and (b) identify practices that are effective at improving the academic performance of students with ED in these settings. Overall, few studies were identified. Of those studies identified, half did not disaggregate outcomes for students with ED. A quality indicator coding based on the What Works Clearinghouse (WWC) design standards revealed that no studies with disaggregated outcomes permitted causal inferences. Implications for school practice and areas for future research are discussed.

  2. A profile of students receiving counselling services at a university in post-apartheid South Africa. (United States)

    Bowman, Brett; Payne, Jarrod


    The purpose of this study was to describe a profile of students seeking counselling at a racially diverse university in post-apartheid South Africa as a means to demonstrate the importance of routinely collecting and analysing student counselling data at university-based centres across the country. Student data were extracted from the only two counselling centres based at the University of the Witwatersrand in Johannesburg that provided services to 831 students during 2008. The 26 243 students that did not seek counselling during this period formed the comparison group. These data were analysed using logistic regression. Black, female and students within the 21-25 year age category were more likely to receive counselling, and presenting problems varied by population group. Given the country's past and continued levels of social asymmetry, we argue that the development of standardised university-based reporting systems able to describe the characteristics and presenting problems of students seeking counselling across South African universities should be prioritised by its higher education sector. Timely access to information of this kind is crucial to the generation of evidence-based mental health interventions in a population that is especially important to the country's development vision.

  5. Supporting student nurses in practice with additional online communication tools. (United States)

    Morley, Dawn A


    Student nurses' potential isolation and difficulties of learning on placement have been well documented and, despite attempts to make placement learning more effective, evidence indicates the continuing schism between formal learning at university and situated learning on placement. First year student nurses, entering placement for the first time, are particularly vulnerable to the vagaries of practice. During 2012 two first year student nurse seminar groups (52 students) were voluntarily recruited for a mixed method study to determine the usage of additional online communication support mechanisms (Facebook, wiki, an email group and traditional methods of support using individual email or phone) while undertaking their first five week clinical placement. The study explores the possibility of strengthening clinical learning and support by promoting the use of Web 2.0 support groups for student nurses. Results indicate a high level of interactivity in both peer and academic support in the use of Facebook and a high level of interactivity in one wiki group. Students' qualitative comments voice an appreciation of being able to access university and peer support whilst working individually on placement. Recommendations from the study challenge universities to use online communication tools already familiar to students to complement the support mechanisms that exist for practice learning. This is tempered by recognition of the responsibility of academics to ensure their students are aware of safe and effective online communication. Copyright © 2013 Elsevier Ltd. All rights reserved.

  9. Additional oligofructose/inulin does not increase faecal bifidobacteria in critically ill patients receiving enteral nutrition: a randomised controlled trial. (United States)

    Majid, Hazreen A; Cole, Jayne; Emery, Peter W; Whelan, Kevin


    Patients with diarrhoea during enteral nutrition (EN) have been shown to have low faecal bifidobacteria concentrations. Oligofructose/inulin selectively stimulate the growth of bifidobacteria in healthy humans. This study investigates the effect of additional oligofructose/inulin on the gastrointestinal microbiota, short-chain fatty acids (SCFA) and faecal output in patients receiving EN. Adult patients in the intensive care unit (ICU) who were starting EN with a formula containing fibre were randomised to receive 7 g/d of additional oligofructose/inulin or an identically packaged placebo (maltodextrin). A fresh faecal sample was collected at baseline and following at least 7 days of supplementation. Faecal microbiota were analysed using fluorescent in-situ hybridisation and faecal output was monitored daily. Twenty-two patients (mean age 71 years) completed at least 7 days of intervention (mean 12 days). At the end of the intervention, there were no significant differences in the concentrations of bifidobacteria between the groups, after adjusting for baseline values (oligofructose/inulin 6.9 + 1.4, placebo 7.8 + 1.3 log10 cells/g dry faeces, P > 0.05), but there were significantly lower concentrations of Faecalibacterium prausnitzii (7.0 + 1.0 vs. 8.4 + 1.3 log10 cells/g, P = 0.01) and Bacteroides-Prevotella (9.1 + 1.0 vs. 9.9 + 0.9 log10 cells/g, P = 0.05) in patients receiving additional oligofructose/inulin. There were no differences in faecal concentrations of any SCFA, secretory IgA, daily faecal score or incidence of diarrhoea between the two groups. Additional oligofructose/inulin did not increase faecal bifidobacteria in critically ill patients receiving EN, although it did result in lower concentrations of F. prausnitzii and Bacteroides-Prevotella.

  10. Using embryology screencasts: a useful addition to the student learning experience? (United States)

    Evans, Darrell J R


    Although podcasting has been a well used resource format in the last few years as a way of improving the student learning experience, the inclusion of enhanced audiovisual formats such as screencasts has been less used, despite the advantage that they work well for both visual and auditory learners. This study examines the use of and student reaction to a set of screencasts introduced to accompany embryology lectures within a second year module at Brighton and Sussex Medical School. Five mini-lecture screencasts and one review quiz screencast were produced as digital recordings of computer screen output with audio narration and released to students via the managed learning environment (MLE). Analysis of server log information from the MLE showed that the screencasts were accessed by many of the students in the cohort, although the exact numbers were variable depending on the screencast. Students accessed screencasts at different times of the day and over the whole of the access period, although maximum downloads were predictably recorded leading up to the written examination. Quantitative and qualitative feedback demonstrated that most students viewed the screencasts favorably in terms of usefulness to their learning, and end-of-module written examination scores suggest that the screencasts may have had a positive effect on student outcome when compared with previous student attainment. Overall, the development of a series of embryology screencasts to accompany embryology lecture sessions appears to be a useful addition to learning for most students and not simply an innovation that checks the box of "technology engagement."

  18. Investigating how students communicate tree-thinking (United States)

    Boyce, Carrie Jo

    Learning is often an active endeavor that requires students work at building conceptual understandings of complex topics. Personal experiences, ideas, and communication all play large roles in developing knowledge of and understanding complex topics. Sometimes these experiences can promote formation of scientifically inaccurate or incomplete ideas. Representations are tools used to help individuals understand complex topics. In biology, one way that educators help people understand evolutionary histories of organisms is by using representations called phylogenetic trees. In order to understand phylogenetics trees, individuals need to understand the conventions associated with phylogenies. My dissertation, supported by the Tree-Thinking Representational Competence and Word Association frameworks, is a mixed-methods study investigating the changes in students' tree-reading, representational competence and mental association of phylogenetic terminology after participation in varied instruction. Participants included 128 introductory biology majors from a mid-sized southern research university. Participants were enrolled in either Introductory Biology I, where they were not taught phylogenetics, or Introductory Biology II, where they were explicitly taught phylogenetics. I collected data using a pre- and post-assessment consisting of a word association task and tree-thinking diagnostic (n=128). Additionally, I recruited a subset of students from both courses (n=37) to complete a computer simulation designed to teach students about phylogenetic trees. I then conducted semi-structured interviews consisting of a word association exercise with card sort task, a retrospective pre-assessment discussion, a post-assessment discussion, and interview questions. I found that students who received explicit lecture instruction had a significantly higher increase in scores on a tree-thinking diagnostic than students who did not receive lecture instruction. Students who received both

  20. Digestive microbiota is different in pigs receiving antimicrobials or a feed additive during the nursery period.

    Directory of Open Access Journals (Sweden)

    Cassandra Soler

    Full Text Available Antimicrobials have been used in a prophylactic way to decrease the incidence of digestive disorders during the piglet post-weaning period. Nowadays, it is urgent to reduce their consumption in livestock to address the problem of antimicrobial resistance. In this study, the effect of a product on piglet microbiota has been investigated as an alternative to antimicrobials. Three groups of ten post-weaning pigs were sampled at 0, 15 and 30 days one week post-weaning; the control, antibiotic and feed additive group received a standard post-weaning diet without antibiotics or additives, the same diet as the control group but with amoxicillin and colistin sulphate and the same diet as the control group but with a feed additive (Sanacore-EN, Nutriad International N.V., respectively. The total DNA extracted from faeces was used to amplify the 16S RNA gene for massive sequencing under manufacturer's conditions. Sequencing data was quality filtered and analyzed using QIIME software and suitable statistical methods. In general terms, age modifies significantly the microbiota of the piglets. Thus, the oldest the animal, the highest bacterial diversity observed for the control and the feed additive groups. However, this diversity was very similar in the antibiotic group throughout the trial. Interestingly, a clear increase in abundance of Bacillus and Lactobacillus spp was detected within the feed additive group versus the antibiotic and control groups. In conclusion, the feed additive group had a positive effect in the endogenous microbiota of post-weaning pigs increasing both, the diversity of bacterial families and the abundance of lactic acid bacteria during the post-weaning period.

    Full Text Available The purpose of this study is to examine the impact of information placement within the confines of the online classroom architecture. Also reviewed was the impact of other variables such as course design, teaching presence and student patterns in looking for information. The sample population included students from a major online university in their first year course sequence. Students were tasked with completing a survey at the end of the course, indicating their preference for accessing information within the online classroom. The qualitative data indicated that student preference is to receive information from multiple access points and sources within the online classroom architecture. Students also expressed a desire to have information delivered through the usage of technology such as email and text messaging. In addition to receiving information from multiple sources, the qualitative data indicated students were satisfied overall, with the current ways in which they received and accessed information within the online classroom setting. Major findings suggest that instructors teaching within the online classroom should have multiple data access points within the classroom architecture. Furthermore, instructors should use a variety of communication venues to enhance the ability for students to access and receive information pertinent to the course.

  7. How to build institutionalization on students: a pilot experiment on a didactical design of addition and subtraction involving negative integers (United States)

    Fuadiah, N. F.; Suryadi, D.; Turmudi


    This study focuses on the design of a didactical situation in addition and subtraction involving negative integers at the pilot experiment phase. As we know, negative numbers become an obstacle for students in solving problems related to them. This study aims to create a didactical design that can assist students in understanding the addition and subtraction. Another expected result in this way is that students are introduced to the characteristics of addition and subtraction of integers. The design was implemented on 32 seventh grade students in one of the classes in a junior secondary school as the pilot experiment. Learning activities were observed thoroughly including the students’ responses that emerged during the learning activities. The written documentation of the students was also used to support the analysis in the learning activities. The results of the analysis showed that this method could help the students perform a large number of integer operations that could not be done with a number line. The teacher’s support as a didactical potential contract was still needed to encourage institutionalization processes. The results of the design analysis used as the basis of the revision are expected to be implemented by the teacher in the teaching experiment.

  14. Ask and you shall receive: desire and receipt of feedback via Facebook predicts disordered eating concerns. (United States)

    Hummel, Alexandra C; Smith, April R


    The current study examined whether certain types of Facebook content (i.e., status updates, comments) relate to eating concerns and attitudes. We examined the effects of seeking and receiving negative feedback via Facebook on disordered eating concerns in a sample of 185 undergraduate students followed for approximately 4 weeks. Results indicated that individuals with a negative feedback seeking style who received a high number of comments on Facebook were more likely to report disordered eating attitudes four weeks later. Additionally, individuals who received extremely negative comments in response to their personally revealing status updates were more likely to report disordered eating concerns four weeks later. Results of the current study provide preliminary evidence that seeking and receiving negative feedback via social networking sites can increase risk for disordered eating attitudes, and suggest that reducing maladaptive social networking usage may be an important target for prevention and intervention efforts aimed at reducing disordered eating attitudes. © 2014 Wiley Periodicals, Inc.

  15. Comparison of nutritional status of rural and urban school students receiving midday meals in schools of Bengaluru, India: a cross sectional study. (United States)

    Shalini, C N; Murthy, N S; Shalini, S; Dinesh, R; Shivaraj, N S; Suryanarayana, S P


    The objective of the study was to assess the impact of the mid day meal program by assessing the nutritional status of school students aged 5-15 years receiving midday meals in rural schools and compare them with those in urban schools in Bengaluru, India. This cross sectional study involved a sample of 4378 students from government and aided schools. Weight and height were measured and compared with ''means'' and ''percentiles'' of expected standards as endorsed by the Indian Association of Pediatrics. Regression coefficients were also estimated to assess the rate of growth. In all age groups and in both sexes, the observed mean weight and height were below the expected standards. The study findings showed that 13.8% and 13.1% of the studied students were underweight and stunted, respectively (below the third percentile for weight and height for age). A higher proportion of rural students were below the third percentile for both weight and height compared with urban students (weight: 16.3% and 11.5%; height: 17.0% and 10.0%; P nutrition in children and indirectly impact school performance, attendance and literacy.

  17. Responsibility-Sharing in the Giving and Receiving of Assessment Feedback

    Directory of Open Access Journals (Sweden)

    Robert A. Nash


    Full Text Available Many argue that effective learning requires students to take a substantial share of responsibility for their academic development, complementing the responsibilities taken by their educators. Yet this notion of responsibility-sharing receives minimal discussion in the context of assessment feedback, where responsibility for enhancing learning is often framed as lying principally with educators. Developing discussion on this issue is critical: many barriers can prevent students from engaging meaningfully with feedback, but neither educators nor students are fully empowered to remove these barriers without collaboration. In this discussion paper we argue that a culture of responsibility-sharing in the giving and receiving of feedback is essential, both for ensuring that feedback genuinely benefits students by virtue of their skilled and proactive engagement, and also for ensuring the sustainability of educators' effective feedback practices. We propose some assumptions that should underpin such a culture, and we consider the practicalities of engendering this cultural shift within modern higher education.

  19. Impact of peer teaching on nursing students: perceptions of learning environment, self-efficacy, and knowledge. (United States)

    Brannagan, Kim B; Dellinger, Amy; Thomas, Jan; Mitchell, Denise; Lewis-Trabeaux, Shirleen; Dupre, Susan


    Peer teaching has been shown to enhance student learning and levels of self efficacy. The purpose of the current study was to examine the impact of peer-teaching learning experiences on nursing students in roles of tutee and tutor in a clinical lab environment. This study was conducted over a three-semester period at a South Central University that provides baccalaureate nursing education. Over three semesters, 179 first year nursing students and 51 third year nursing students participated in the study. This mixed methods study, through concurrent use of a quantitative intervention design and qualitative survey data, examined differences during three semesters in perceptions of a clinical lab experience, self-efficacy beliefs, and clinical knowledge for two groups: those who received peer teaching-learning in addition to faculty instruction (intervention group) and those who received faculty instruction only (control group). Additionally, peer teachers' perceptions of the peer teaching learning experience were examined. Results indicated positive response from the peer tutors with no statistically significant differences for knowledge acquisition and self-efficacy beliefs between the tutee intervention and control groups. In contrast to previous research, students receiving peer tutoring in conjunction with faculty instruction were statistically more anxious about performing lab skills with their peer tutor than with their instructors. Additionally, some students found instructors' feedback moderately more helpful than their peers and increased gains in knowledge and responsibility for preparation and practice with instructors than with peer tutors. The findings in this study differ from previous research in that the use of peer tutors did not decrease anxiety in first year students, and no differences were found between the intervention and control groups related to self efficacy or cognitive improvement. These findings may indicate the need to better prepare peer

  20. Otolaryngology residency selection process. Medical student perspective. (United States)

    Stringer, S P; Cassisi, N J; Slattery, W H


    In an effort to improve the otolaryngology matching process at the University of Florida, Gainesville, we sought to obtain the medical student's perspective of the current system. All students who interviewed here over a 3-year period were surveyed regarding the application, interview, and ranking process. In addition, suggestions for improving the system were sought from the students. The application and interviewing patterns of the students surveyed were found to be similar to those of the entire otolaryngology residency applicant pool. We were unable to identify any factors that influence a student's rank list that could be prospectively used to help select applicants for interview. A variety of suggestions for improvements in the match were received, several of which could easily be instituted. A uniform interview invitation date as requested by the students could be rapidly implemented and would provide benefits for both the students and the residency programs.

  1. Assessing the Process of Receiving Students’ Meals in Tabriz University of Medical Sciences in 2012

    Directory of Open Access Journals (Sweden)

    Farahnaz Varmazyar


    Full Text Available ​ Background and Objectives : The process of receiving meal is one of the most important daily events of university students and managers. Since this process happens within a limited time during the day, and all the students are directly involved in this process, proper management is one  of the main factors of conducting this process appropriately. The aim of this study was to evaluate the process of receiving meals step by step and analyzing how this process takes place and finally offer some strategies for promoting the quality of conducting this process at Tabriz University of Medical Sciences. Material and Methods : The is a cross-sectional study which was conducted by observation, interview and the questionnaires filled out by students and automation section staff. The flowchart for the process of receiving meals of the university was drawn after step by step observation. The questionnaire including 14 questions were answered by 60 students randomly. A suggested flowchart was adjusted after general and specialized analysis of the flowchart in 5W1H method. For analyzing data, Excel 2007 software was applied. Results : Data analysis indicated that 55% of the students believed that too much time was wasted in this process. Currently, each student spends about 43 minutes for having lunch everyday. Although the university has facilitated food reservation by internet, 80% of students do not use this service and refer to self-service restaurant operators and cause long queues . After interviewing with the manager of food section, it was specified that an average amount of Rls. 300,000,000/- is allocated daily for students’ food by students’ deputy which is Rls. 100,000/- for each student and each student pays only 6.5% of the whole price and 93.5% of the price is supplied by students’ welfare affairs deputy. Conclusion: The process of receiving meals of students at Tabriz University of Medical Sciences is a time-consuming process and

  2. Student teachers’ mathematical questioning and courage in metaphorical thinking learning (United States)

    Hendriana, H.; Hidayat, W.; Ristiana, M. G.


    This study was designed in the form of experiments with control group design and post-test only which aimed to examine the role of metaphorical thinking learning in the mathematical questioning ability of student teachers based on the level of mathematical courage. The population of this study was student teachers of mathematics education study program in West Java Province, while the sample of this study was 152 student teachers which were set purposively and then randomly to be included in the experimental class and control class. Based on the results and discussion, it was concluded that: (a) the mathematical questioning ability of student teachers who received Metaphorical Thinking learning was better than those who received conventional learning seen from mathematical courage level; (b) learning and mathematical courage level factors affected the achievement of student teachers’ mathematical questioning ability. In addition, there was no interaction effect between learning and mathematical courage level (high, medium, and low) simultaneously in developing student teachers’ mathematical questioning ability; (c) achievement of mastering mathematical questioning ability of student teacher was still not well achieved on indicator of problem posing in the form of non-routine question and open question.

  3. Student pharmacists' perceptions of immunizations. (United States)

    Kubli, Kara; McBane, Sarah; Hirsch, Jan D; Lorentz, Sarah


    The primary aim of this study was to explore changes in knowledge level, perceived importance and apprehension of immunizations by first year pharmacy students pre- vs. post-immunization education and training. First year pharmacy students at the University of California San Diego Skaggs School of Pharmacy and Pharmaceutical Sciences (UC San Diego SSPPS) completed a pre- and post-immunization training course questionnaire. Knowledge base and perceived importance level of immunizations including hepatitis B, influenza, measles, mumps, rubella (MMR), varicella, tetanus, diphtheria, pertussis (Tdap), meningococcal and human papilloma virus (HPV) were assessed. In addition, apprehension of needle administration and fears regarding safety and efficacy were evaluated. Of 120 students, 85 (71%) completed pre- and post-course questionnaires for this study. Mean knowledge test scores increased from 56% pre-course to 83% post-course. Pre-course, 73% of participants considered immunizations as very important in preventing future disease outbreaks. Post-course, this percentage climbed to 94%. Prior to taking the course, 52% of students were apprehensive about administering injections; however, after completing the course this percentage declined to 33%. The majority of students who had been fearful prior to the course retained their fears of receiving needle injections. The proportion of students believing immunizations should be a personal choice, not mandatory, did not significantly change from pre-course (49%) to post-course (44%). The UC San Diego SSPPS immunization course increased student knowledge of immunization facts and the perceived importance of immunizations. However, a substantial portion of students retained apprehension about administering and receiving needle injections and the proportion believing immunizations should be a personal choice, almost half, did not change appreciably.

    Rafique, M.; Rahman, S. U.; Rahman, S.; Matiullah; Shahzad, M. I.; Ahmed, N.; Iqbal, J.; Ahmed, B.; Ahmed, T.; Akhtar, N.


    Several epidemiological studies conducted on thousands of underground miners suggest that long-term exposure to high radon concentration can increase the risk of lung cancer. Keeping in view the importance of the subject, numerous studies throughout the world have been carried out to measure indoor radon concentration and its resulting doses at occupational and non-occupational sites. The purpose of the current study was to measure indoor radon concentration and its resulting doses received by the students of Azad Kashmir government schools. For this purpose, CR-39 radon detectors were installed in 80 carefully selected schools. The detectors were placed at a height of 3-5 ft. (depending upon average height of students in particular class) from the ground. After exposure of 90 d detectors were etched for 9 h in 6 M NaOH at 70 deg. C and the observed track densities were related to radon concentrations. The measured indoor radon concentration ranged from 22 ± 9 to 228 ± 3 Bq m -3 with a mean value of 78 ± 5 Bq m -3 . Based on the measured indoor radon data, the annual effective doses were found to vary from 0.55 ± 0.04 to 0.71 ± 0.03 mSv y -1 . The overall mean effective dose for the studied area was found to be 0.63 ± 0.04 mSv y -1 . Reported values for radon concentrations and corresponding doses are lower than ICRP recommended limits for workplaces. (authors)

  7. Attitude of Pharmacy Students Towards a Nutrition Course (United States)

    Syed Abdul, Majid Mufaqam

    Today's pharmacists are likely to encounter questions about nutritional products sold in the pharmacy. This is due, in part, to the increased number of pharmacies attached to grocery stores and the availability of pharmacists. Many pharmacists report they lack nutritional knowledge and believe the best time to educate pharmacists about nutrition is during pharmacy school. This study was conducted to determine if today's pharmacy students receive education in nutrition and if they realize the importance of nutrition education. Two hundred and twenty five students from India and ninety five students from the United States currently attending pharmacy school were surveyed. Results showed only 3.5% of students from India and 13.6% of students from the United States received nutrition education during their pharmacy degree curriculum. In addition, 81.8% of students from India and 82.9% of students from the United States who had taken a course in nutrition believed a nutrition course should be incorporated into the pharmacy degree curriculum. When pharmacy-related experience was taken into account, 92.9% of students from India and 73.3% of students from the United States also believed a nutrition course should be incorporated into the pharmacy degree curriculum. Overall, 88% of students from India and 70.5% of students from the United States believed nutrition education was important and should be included in the pharmacy degree curriculum. Results of this study suggest the majority of today's pharmacy students believe a nutrition course should be incorporated into the pharmacy degree curriculum regardless of past nutrition education or pharmacy-related experience.

  8. Predicting the academic performance of Asian, black, and Hispanic optometry students. (United States)

    Kegel-Flom, P


    As optometry schools receive increasing numbers of Asian, Black, and Hispanic applications, it is appropriate for us to ask whether minority students differ in meaningful ways from nonminority students in measures used in admissions, and whether these variables have differential validity in predicting their achievement in optometry school. This study compares Asian, Black, Hispanic, and nonminority students at entry to the University of Houston College of Optometry (UHCO) from 1981 through 1986 and tests the validity of admissions indices to predict optometry grades, academic dropout, and high-level achievement for these ethnic groups. Although preoptometry grade point average (GPA) was the best predictor of optometry grades for all students, measures of verbal ability were additional predictors for Asian students and, for Black and Hispanic students, ability in study/reading and math were predictors. In addition, personality inventory measures and ratings of the competitiveness of the undergraduate institution were important in differentiating minority academic dropouts from retained students. Suggestions are made for optometry college programs which will enhance the probability of success for minority students.

  9. "Hot Seat" Questioning: A Technique to Promote and Evaluate Student Dialogue (United States)

    Crider, Anthony

    Several approaches have been proposed to include students in classroom dialogue, including "think-pair-share" and "talk to your neighbor." I recently implemented an additional technique in which four students answer questions in a "Hot Seat" at the front of the classroom. An unforeseen by-product of this was student-initiated peer instruction outside of the classroom. A small case study (approximately 50 students) on the effect of the Hot Seat using the midterm exam showed that students were 9.5 +/- 3.2% more likely to correctly answer a question related to material covered while they occupied the Hot Seat. Analysis of the Astronomy Diagnostic Test revealed that they were twice as likely to learn their Hot Seat material. A survey revealed one likely reason: Students typically spent 15-60 additional minutes preparing for class on their two assigned Hot Seat dates. Curiously, students received no significant benefit (2.2 +/- 3.6%) from their second turn in the Hot Seat, possibly reflecting student immunization to its motivational pressure.

  10. Learning difficulties or learning English difficulties? Additional language acquisition: an update for paediatricians. (United States)

    Clifford, Vanessa; Rhodes, Anthea; Paxton, Georgia


    Australia is a diverse society: 26% of the population were born overseas, a further 20% have at least one parent born overseas and 19% speak a language other than English at home. Paediatricians are frequently involved in the assessment and management of non-English-speaking-background children with developmental delay, disability or learning issues. Despite the diversity of our patient population, information on how children learn additional or later languages is remarkably absent in paediatric training. An understanding of second language acquisition is essential to provide appropriate advice to this patient group. It takes a long time (5 years or more) for any student to develop academic competency in a second language, even a student who has received adequate prior schooling in their first language. Refugee students are doubly disadvantaged as they frequently have limited or interrupted prior schooling, and many are unable to read and write in their first language. We review the evidence on second language acquisition during childhood, describe support for English language learners within the Australian education system, consider refugee-background students as a special risk group and address common misconceptions about how children learn English as an additional language. © 2013 The Authors.

    We chose high school students, who are expected to show significant response to education, to try to understand perception and behavior toward irradiated food, and derive evidential materials for education. High school students who had ever acquired information or received education on irradiated food, and students who had ever purchased or eaten irradiated food, tended to have aproper attitude regarding its necessity, safety, and purchase without prejudice. It is necessary to provide information and education to high school students. Additionally, exposure to the irradiated food could be helpful in changing perception and attitude toward irradiated food.

  14. Alcohol Use and Problems in Mandated College Students: A Randomized Clinical Trial Using Stepped Care (United States)

    Borsari, Brian; Hustad, John T.P.; Mastroleo, Nadine R.; Tevyaw, Tracy O’Leary; Barnett, Nancy P.; Kahler, Christopher W.; Short, Erica Eaton; Monti, Peter M.


    Objective Over the past two decades, colleges and universities have seen a large increase in the number of students referred to the administration for alcohol policies violations. However, a substantial portion of mandated students may not require extensive treatment. Stepped care may maximize treatment efficiency and greatly reduce the demands on campus alcohol programs. Method Participants in the study (N = 598) were college students mandated to attend an alcohol program following a campus-based alcohol citation. All participants received Step 1: a 15-minute Brief Advice session that included the provision of a booklet containing advice to reduce drinking. Participants were assessed six weeks after receiving the Brief Advice, and those who continued to exhibit risky alcohol use (n = 405) were randomized to Step 2, a 60–90 minute brief motivational intervention (BMI) (n = 211) or an assessment-only control (n = 194). Follow-up assessments were conducted 3, 6, and 9 months after Step 2. Results Results indicated that the participants who received a BMI significantly reduced the number of alcohol-related problems compared to those who received assessment-only, despite no significant group differences in alcohol use. In addition, low risk drinkers (n = 102; who reported low alcohol use and related harms at 6-week follow-up and were not randomized to stepped care) showed a stable alcohol use pattern throughout the follow-up period, indicating they required no additional intervention. Conclusion Stepped care is an efficient and cost-effective method to reduce harms associated with alcohol use by mandated students. PMID:22924334

    Chamberlain, Neal R; Stuart, Melissa K; Singh, Vineet K; Sargentini, Neil J


    Small-group case presentation exercises (CPs) were created to increase course relevance for medical students taking Medical Microbiology (MM) and Infectious Diseases (ID) METHODS: Each student received a unique paper case and had 10 minutes to review patient history, physical exam data, and laboratory data. Students then had three minutes to orally present their case and defend why they ruled in or out each of the answer choices provided, followed by an additional three minutes to answer questions. Exam scores differed significantly between students who received the traditional lecture-laboratory curriculum (Group I) and students who participated in the CPs (Group II). In MM, median unit exam and final exam scores for Group I students were 84.4% and 77.8%, compared to 86.0% and 82.2% for Group II students (P<0.018; P<0.001; Mann-Whitney Rank Sum Test). Median unit and final ID exam scores for Group I students were 84.0% and 80.0%, compared to 88.0% and 86.7% for Group II students (P<0.001; P<0.001). Students felt that the CPs improved their critical thinking and presentation skills and helped to prepare them as future physicians.

  5. Needs and preferences regarding sex education among Chinese college students: a preliminary study. (United States)

    Li, Ying; Cottrell, Randall R; Wagner, Donald I; Ban, Maosheng


    College students are more likely than other student populations to be sexually active. To improve sex education in China among this group, educators must know college students' needs and their preferences for receiving information on sexuality. In 2002, students at a large Chinese university completed surveys about their history of school-based sex education and their other sources of information on sexuality. The survey also explored students' preferences for topics to be included in a college-level sex education course, comfort level with receiving information on these topics and views of effective teaching strategies. Before college, 47% of respondents had received no school-based education on sexual behavior; however, all respondents had taken a class covering reproduction, typically beginning in middle school (78%). Reading material, radio, classroom lecture and parents were more popular sources of information among females than among males; friends, the Internet and personal sexual experience were more frequent sources for males than for females. Higher proportions of males than females favored including sex therapy and masturbation in a hypothetical course. In addition, males felt more comfortable than females discussing 11 of 20 subjects; the two genders indicated similar levels of comfort in talking about the other topics. Males and females differed on how best to convey information on sexuality, with females generally favoring private methods, such as reading. More comprehensive school-based sex education is needed for Chinese youth. When developing and implementing such programs, health educators should consider differences between males' and females' preferred ways for receiving information on sexuality.

    C N Shalini


    Full Text Available Background: The objective of the study was to assess the impact of the mid day meal program by assessing the nutritional status of school students aged 5-15 years receiving midday meals in rural schools and compare them with those in urban schools in Bengaluru, India. Materials and Methods: This cross sectional study involved a sample of 4378 students from government and aided schools. Weight and height were measured and compared with ′′means′′ and ′′percentiles′′ of expected standards as endorsed by the Indian Association of Pediatrics. Regression coefficients were also estimated to assess the rate of growth. Results: In all age groups and in both sexes, the observed mean weight and height were below the expected standards. The study findings showed that 13.8% and 13.1% of the studied students were underweight and stunted, respectively (below the third percentile for weight and height for age. A higher proportion of rural students were below the third percentile for both weight and height compared with urban students (weight: 16.3% and 11.5%; height: 17.0% and 10.0%; P < 0.05 for both weight and height. Only 2.4% and 3.1% were above 97 th percentile for weight and height. The rate of growth of height for weight showed a declining trend with increasing age in all the groups. Discussion: The authors believe that the magnitude of the burden of undernourished students as seen in this study would have been much greater in the absence of the midday meal program. Conclusion: Greater involvement of the private sector to assist the government would help augment nutrition in children and indirectly impact school performance, attendance and literacy.

  7. Just as smart but not as successful: obese students obtain lower school grades but equivalent test scores to nonobese students. (United States)

    MacCann, C; Roberts, R D


    The obesity epidemic in industrialized nations has important implications for education, as research demonstrates lower academic achievement among obese students. The current paper compares the test scores and school grades of obese, overweight and normal-weight students in secondary and further education, controlling for demographic variables, personality, ability and well-being confounds. This study included 383 eighth-grade students (49% female; study 1) and 1036 students from 24 community colleges and universities (64% female, study 2), both drawn from five regions across the United States. In study 1, body mass index (BMI) was calculated using self-reports and parent reports of weight and height. In study 2, BMI was calculated from self-reported weight and height only. Both samples completed age-appropriate assessments of mathematics, vocabulary and the personality trait conscientiousness. Eighth-grade students additionally completed a measure of life satisfaction, with both self-reports and parent reports of their grades from the previous semester also obtained. Higher education students additionally completed measures of positive and negative affect, and self-reported their grades and college entrance scores. Obese students receive significantly lower grades in middle school (d=0.83), community college (d=0.34) and university (d=0.36), but show no statistically significant differences in intelligence or achievement test scores. Even after controlling for demographic variables, intelligence, personality and well-being, obese students obtain significantly lower grades than normal-weight students in the eighth grade (d=0.39), community college (d=0.42) and university (d=0.31). Lower grades may reflect peer and teacher prejudice against overweight and obese students rather than lack of ability among these students.

  8. Sequential mediating effects of provided and received social support on trait emotional intelligence and subjective happiness: A longitudinal examination in Hong Kong Chinese university students. (United States)

    Ye, Jiawen; Yeung, Dannii Y; Liu, Elaine S C; Rochelle, Tina L


    Past research has often focused on the effects of emotional intelligence and received social support on subjective well-being yet paid limited attention to the effects of provided social support. This study adopted a longitudinal design to examine the sequential mediating effects of provided and received social support on the relationship between trait emotional intelligence and subjective happiness. A total of 214 Hong Kong Chinese undergraduates were asked to complete two assessments with a 6-month interval in between. The results of the sequential mediation analysis indicated that the trait emotional intelligence measured in Time 1 indirectly influenced the level of subjective happiness in Time 2 through a sequential pathway of social support provided for others in Time 1 and social support received from others in Time 2. These findings highlight the importance of trait emotional intelligence and the reciprocal exchanges of social support in the subjective well-being of university students. © 2018 International Union of Psychological Science.

  10. Integrating technology, curriculum, and online resources: A multilevel model study of impacts on science teachers and students (United States)

    Ye, Lei

    This scale-up study investigated the impact of a teacher technology tool (Curriculum Customization Service, CCS), curriculum, and online resources on earth science teachers' attitudes, beliefs, and practices and on students' achievement and engagement with science learning. Participants included 73 teachers and over 2,000 ninth-grade students within five public school districts in the western U.S. To assess the impact on teachers, changes between pre- and postsurveys were examined. Results suggest that the CCS tool appeared to significantly increase both teachers' awareness of other earth science teachers' practices and teachers' frequency of using interactive resources in their lesson planning and classroom teaching. A standard multiple regression model was developed. In addition to "District," "Training condition" (whether or not teachers received CCS training) appeared to predict teachers' attitudes, beliefs, and practices. Teachers who received CCS training tended to have lower postsurvey scores than their peers who had no CCS training. Overall, usage of the CCS tool tended to be low, and there were differences among school districts. To assess the impact on students, changes were examined between pre- and postsurveys of (1) knowledge assessment and (2) students' engagement with science learning. Students showed pre- to postsurvey improvements in knowledge assessment, with small to medium effect sizes. A nesting effect (students clustered within teachers) in the Earth's Dynamic Geosphere (EDG) knowledge assessment was identified and addressed by fitting a two-level hierarchical linear model (HLM). In addition, significant school district differences existed for student post-knowledge assessment scores. On the student engagement questionnaire, students tended to be neutral or to slightly disagree that science learning was important in terms of using science in daily life, stimulating their thinking, discovering science concepts, and satisfying their own

  11. Online Embryology teaching using learning management systems appears to be a successful additional learning tool among Egyptian medical students. (United States)

    Al-Neklawy, Ahmed Farid


    Although the traditional didactic lecture is considered to be efficient for presenting information and providing explanations, it usually does not provide adequate time for deeper learning activities. So, traditional lecture is one of the most widely criticized educational methods. Virtual learning environment (VLE) is a specially designed environment that facilitates teachers' management of educational courses for their students, using computer hardware and software, which involves distance learning. In this study, we evaluated the experiment of online teaching of General Embryology for Egyptian undergraduate medical students using WizIQ learning management system. A total of 100 students were invited to submit an online survey at the end of the course to evaluate delivery of instruction, creation of an environment that supported learning, and administrative issues. Most of the students reported that they were strongly satisfied with the efficacy of the instructional methods and were strongly satisfied with the degree of clarity of the course material. They strongly accepted the page format and design of the virtual classroom and strongly agreed that the learning environment supported the learning procedure. The item of easy logging into the virtual classroom had aberrant variable responses; it recorded the lowest mean response; this variation in responses was due to technical factors as the students used different devices with different speeds of internet connections. Ninety percent of students have strongly recommended the course attendance for their fellow students. These results demonstrate that online Anatomy teaching using learning management systems appears to be a successful additional learning tool among Egyptian medical students.

  13. 'Students-as-partners' scheme enhances postgraduate students' employability skills while addressing gaps in bioinformatics education. (United States)

    Mello, Luciane V; Tregilgas, Luke; Cowley, Gwen; Gupta, Anshul; Makki, Fatima; Jhutty, Anjeet; Shanmugasundram, Achchuthan


    Teaching bioinformatics is a longstanding challenge for educators who need to demonstrate to students how skills developed in the classroom may be applied to real world research. This study employed an action research methodology which utilised student-staff partnership and peer-learning. It was centred on the experiences of peer-facilitators, students who had previously taken a postgraduate bioinformatics module, and had applied knowledge and skills gained from it to their own research. It aimed to demonstrate to peer-receivers, current students, how bioinformatics could be used in their own research while developing peer-facilitators' teaching and mentoring skills. This student-centred approach was well received by the peer-receivers, who claimed to have gained improved understanding of bioinformatics and its relevance to research. Equally, peer-facilitators also developed a better understanding of the subject and appreciated that the activity was a rare and invaluable opportunity to develop their teaching and mentoring skills, enhancing their employability.

  14. Decision support system for determining Bantuan Siswa Miskin (BSM) receivers with profile matching method (United States)

    Situmorang, B. H.; Pibriana, E.; Tosida, E. T.


    Bantuan Siswa Miskin (BSM) is a National Programs aimed at eliminating the barriers of poor students participating to school by helping poor students gain access to appropriate education services, prevent dropping out of school, attract poor students back to school, assis students in providing for learning activities, support the Nine Years Basic Education (and even up to senior high school) program, as well as helping to smooth the school programs [1]. Decision Support System is made by applying Profile Matching method to assist teachers or school operators in SMP PGRI Ciasmara in selecting prospective recipients of BSM program and providing recommendations in decision making. Profile Matching is used to compare the actual data value of a profile to be assessed by the expected profile value, so that it can be known the difference of competence (also called GAP). If the resulting value of GAP is smaller then the weight of value will be greater, which means it has a greater chance to be recommended as a potential recipient of the BSM program. Decision Support System for determining BSM receivers is only choosing the right alternatives to receive BSM according to the BSM quota given to SMP PGRI Ciasmara. The right alternatives to receive this BSM is the highest ranking alternatives.

  17. Receiver gain function: the actual NMR receiver gain


    Mo, Huaping; Harwood, John S.; Raftery, Daniel


    The observed NMR signal size depends on the receiver gain parameter. We propose a receiver gain function to characterize how much the raw FID is amplified by the receiver as a function of the receiver gain setting. Although the receiver is linear for a fixed gain setting, the actual gain of the receiver may differ from what the gain setting suggests. Nevertheless, for a given receiver, we demonstrate that the receiver gain function can be calibrated. Such a calibration enables accurate compar...

  20. Enhancement of anatomical learning and developing clinical competence of first-year medical and allied health profession students. (United States)

    Keim Janssen, Sarah A; VanderMeulen, Stephane P; Shostrom, Valerie K; Lomneth, Carol S


    Hands-on educational experiences can stimulate student interest, increase knowledge retention, and enhance development of clinical skills. The Lachman test, used to assess the integrity of the anterior cruciate ligament (ACL), is commonly performed by health care professionals and is relatively easy to teach to first-year health profession students. This study integrated teaching the Lachman test into a first-year anatomy laboratory and examined if students receiving the training would be more confident, competent, and if the training would enhance anatomical learning. First-year medical, physician assistant and physical therapy students were randomly assigned into either the intervention (Group A) or control group (Group B). Both groups received the course lecture on knee anatomy and training on how to perform the Lachman test during a surface anatomy class. Group A received an additional 15 minutes hands-on training for the Lachman test utilizing a lightly embalmed cadaver as a simulated patient. One week later, both groups performed the Lachman test on a lightly embalmed cadaver and later completed a post-test and survey. Students with hands-on training performed significantly better than students with lecture-only training in completing the checklist, a post-test, and correctly diagnosing an ACL tear. Students in Group A also reported being more confident after hands-on training compared to students receiving lecture-only training. Both groups reported that incorporating clinical skill activities facilitated learning and created excitement for learning. Hands-on training using lightly embalmed cadavers as patient simulators increased confidence and competence in performing the Lachman test and aided in learning anatomy. © 2013 American Association of Anatomists.

    Kimberly M. Tartaglia


    Full Text Available Introduction: As health systems find ways to improve quality of care, medical training programs are finding opportunities to prepare learners on principles of quality improvement (QI. The impact of QI curricula for medical students as measured by student learning is not well delineated. The aim of this study is to evaluate the effectiveness of a QI curriculum for senior medical students as measured by student knowledge and skills. Methods: This study was an observational study that involved a self-assessment and post-test Quality Improvement Knowledge Application Tool (QIKAT for intervention and control students. A QI curriculum consisting of online modules, live discussions, independent readings and reflective writing, and participation in a mentored QI project was offered to fourth-year medical students completing an honor's elective (intervention group. Senior medical students who received the standard QI curriculum only were recruited as controls. Results: A total of 22 intervention students and 12 control students completed the self-assessment and QIKAT. At baseline, there was no difference between groups in self-reported prior exposure to QI principles. Students in the intervention group reported more comfort with their skills in QI overall and in 9 of the 12 domains (p<0.05. Additionally, intervention students performed better in each of the three case scenarios (p<0.01. Discussion: A brief QI curriculum for senior medical students results in improved comfort and knowledge with QI principles. The strengths of our curriculum include effective use of classroom time and faculty mentorship with reliance on pre-existing online modules and written resources. Additionally, the curriculum is easily expandable to larger groups of students and transferable to other institutions.

    Kanji, Nasim; White, Adrian; Ernst, Edzard


    This paper reports a study to determine the effectiveness of autogenic training in reducing anxiety in nursing students. Nursing is stressful, and nursing students also have the additional pressures and uncertainties shared with all academic students. Autogenic training is a relaxation technique consisting of six mental exercises and is aimed at relieving tension, anger and stress. Meta-analysis has found large effect sizes for autogenic trainings intervention comparisons, medium effect sizes against control groups, and no effects when compared with other psychological therapies. A controlled trial with 50 nursing students found that the number of certified days off sick was reduced by autogenic training compared with no treatment, and a second trial with only 18 students reported greater improvement in Trait Anxiety, but not State Anxiety, compared with untreated controls. A randomized controlled trial with three parallel arms was completed in 1998 with 93 nursing students aged 19-49 years. The setting was a university college in the United Kingdom. The treatment group received eight weekly sessions of autogenic training, the attention control group received eight weekly sessions of laughter therapy, and the time control group received no intervention. The outcome measures were the State-Trait Anxiety Inventory, the Maslach Burnout Inventory, blood pressure and pulse rate completed at baseline, 2 months (end of treatment), and 5, 8, and 11 months from randomization. There was a statistically significantly greater reduction of State (Pautogenic training group than in both other groups immediately after treatment. There were no differences between the groups for the Maslach Burnout Inventory. The autogenic training group also showed statistically significantly greater reduction immediately after treatment in systolic (PAutogenic training has at least a short-term effect in alleviating stress in nursing students.

    Ozcelik, Hanife; Tekir, Ozlem; Samancioglu, Sevgin; Fadiloglu, Cicek; Ozkara, Erdem


    In Turkey, which is a secular, democratic nation with a majority Muslim population, euthanasia is illegal and regarded as murder. Nurses and students can be faced with ethical dilemmas and a lack of a legal basis, with a conflict of religious beliefs and social and cultural values concerning euthanasia. The aim of this study was to investigate undergraduate nursing students' attitudes towards euthanasia. The study, which had a descriptive design, was conducted with 600 students. The 1st, 2nd, 3rd, and 4th year nursing students at a school of nursing were contacted in May 2009, and 383 students (63.8% of the study population of a total of 600 students) gave informed consent. Two tools were used in accordance with questionnaire preparation rules. The majority of students were female and single (96.9%), and their mean age was 21.3 ± 1.5 years. A majority (78.9%) stated they had received no training course/education on the concept of euthanasia. Nearly one-third (32.4%) of the students were against euthanasia; 14.3% of the students in the study agreed that if their relatives had an irreversible, lethal condition, passive euthanasia could be performed. In addition, 24.8% of the students agreed that if they themselves had an irreversible, lethal condition, passive euthanasia could be performed. Less than half (42.5%) of the students thought that discussions about euthanasia could be useful. There was a significant relation between the study year and being against euthanasia (p euthanasia could be abused (p euthanasia was unethical (p euthanasia.

    Goktas, Sonay; Yildirim, Gulay; Kose, Selmin; Yildirim, Senay; Ozhan, Fatma; Senturan, Leman


    Poisoning is a crucial public health problem which needs serious approach and response to treatment. In case of poisoning, proper first aid is lifesaving and application should be applied in every condition. This research was conducted in order to evaluate first aid knowledge of university students for poisoning. The research was conducted between the dates of May 2013-June 2013 with the permission gained from the University Rectorship. The cohort of the research contained 4,560 students who received education in Istanbul. The sample of the study included 936 students who accepted to participate in the research and attended the school during the research. The data were collected by using a questionnaire form, which had 21 questions prepared by researchers. Analysis of the data was carried out with a percentage evaluation method and chi square tests in a computer environment. In our study, 92.6% of students (n=867) knew the phone number of the ambulance in case of emergency. In addition, 57.3% of students (n=536) knew the phone number of the poison hotline, and it was seen that they answered correctly the questions regarding the relation between body system and indications of poisoning. It was determined that the students who received education in medical departments answered the questions correctly more than the students who had education in other departments. (p≤0.001, p≤0.01). It was observed that the university students in medical departments had more first aid knowledge on poisoning cases compared to the students in other departments who did not have sufficient information regarding these issues. It is thought that first aid education in all departments of universities, both poisoning and other first aid issues, should be conveyed to all students.

  8. Students' benefits and barriers to mental health help-seeking (United States)

    Vidourek, Rebecca A.; King, Keith A.; Nabors, Laura A.; Merianos, Ashley L.


    Stigma is recognized as a potential barrier to seeking help for a mental health disorder. The present study assessed college students' perceived benefits and barriers to obtaining mental health treatment and stigma-related attitudes via a four-page survey. A total of 682 students at one Midwestern university participated in the study. Findings indicated that females perceived a greater number of benefits to having participated in mental health services and held significantly lower stigma-related attitudes than did males. Students who had ever received mental health services reported significantly more barriers to treatment than did students who had never received services. Health professionals should target students with educational programs about positive outcomes related to receiving mental health services and work with treatment centers to reduce barriers for receiving services.

  10. UAF Space Systems Engineering Program: Engaging Students through an Apprenticeship Model (United States)

    Thorsen, D.


    Learning by doing has been the mantra of engineering education for decades, however, the constraints of semester length courses limits the types and size of experiences that can be offered to students. The Space Systems Engineering Program (SSEP) at the University of Alaska Fairbanks provides interdisciplinary engineering and science students with hands-on experience in all aspects of space systems engineering through a design, build, launch paradigm applied to balloon and rocket payloads and small satellites. The program is structured using an apprenticeship model such that students, freshmen through graduate, can participate in multi-year projects thereby gaining experiences appropriate to their level in college. Students enter the lab in a trainee position and receive training on lab processes and design software. Depending on the student's interests they learn how to use specific lab equipment and software design tools. Trainees provide support engineering under guidance of an upper classman. As the students' progress in their degree program and gain more expertise, they typically become part of a specific subsystem team, where they receive additional training in developing design documents and in writing requirements and test documents, and direct their efforts to meeting specific objectives. By the time the student reaches their senior year, they have acquired the leadership role for a specific subsystem and/or a general leadership role in the lab. If students stay to pursue graduate degrees, they assume the responsibility of training and mentoring other undergraduates in their areas of expertise. Throughout the program upper class students mentor the newer students. The Space Systems Engineering Program strives to reinforce a student's degree program through these large scale projects that place engineering in context.

  13. Development of an Interdisciplinary STEM Classroom Activity for Radio Receiver Technology (United States)

    Davis, Kristina


    Introduction The development of a mini STEM-based classroom activity designed to integrate these two fields into one project for middle school aged students is presented here. This lesson involves small groups of students constructing a small AM radio receivers. The lesson surrounding the activity focuses on both the physical nature of electromagnetic and AC waves, circuit design, practical applications to AM radio broadcasting, and research applications of radio telescopes. These tools have shown a significant increase in the lesson's primary concept understanding among 6th grade students, as well as net positive STEM awareness and enthusiasm.Content The primary teaching point for the students to consider and learn during this lesson is 'How does scientific application influence engineering design, and vice versa?' The lesson surrounds the hands-on activity of having students construct their own AM radio receiver. Wave theory and the use of radio instruments for astronomy research are also taught in a traditional lecture format. The activity is designed to complement middle school curriculum, although it has been tested and found suitable for high school and older students as well as the general public.Evaluation and ImpactThe evaluation tool that used for the student groups in this project was a Fryer chart, which is a four panel chart with the main topic listed in the center and a single question in each of the four panels. The students are asked to answer the questions in the chart before and after they participate in the lesson activity, each time in a different colored pencil so that the scores can be given to each student before and after they participated in the activity. Student scores improved from 4.5 to 17.9 out of a total of 20 possible points. This is an overall increase of 67% of the total possible points. The questions asked on the quiz cover the range of wave theory, circuit design, and scientific explanation. This factor of improvement shows that

  14. Who receives cannabis use offers: A general population study of adolescents. (United States)

    Burdzovic Andreas, Jasmina; Pape, Hilde


    Drug use is predicated on a combination of "willingness" and "opportunity". That is, independent of any desire to use drugs, a drug use opportunity is required; be it indirect (i.e., being in a drug-use setting) or direct (i.e., receiving a direct drug offer). However, whether some youth are more likely to encounter such direct drug use opportunities is not fully known. We examined whether certain characteristics placed adolescents at greater risk for being offered cannabis, after accounting for a number of demographic-, contextual-, interpersonal-, and personal-level risk factors. We utilized data from a Norwegian school survey (n=19,309) where the likelihood of receiving cannabis offer in the past year was estimated using logistic regression models. Substantive focus was on the individual and combined effects of personal (i.e., delinquency) and interpersonal (i.e., cannabis-using close friend) risk factors. Separate models were fit for middle- and high-school students. Delinquency was a significant risk factor for receiving cannabis offers, as was a cannabis-using best friend. In addition, peer cannabis use increased the risk of cannabis offers mostly for adolescents on the lower delinquency spectrum, but less so for highly delinquent adolescents. These interaction effects were primarily driven by the middle-school cohort. Cannabis offers were more likely to be extended to youth of certain high-risk profiles. Targeted prevention strategies can therefore be extended to a general profile of younger adolescents with externalizing problems and cannabis-using peers. Copyright © 2015 Elsevier Ireland Ltd.

  16. Review: typically-developing students' views and experiences of inclusive education. (United States)

    Bates, Helen; McCafferty, Aileen; Quayle, Ethel; McKenzie, Karen


    The present review aimed to summarize and critique existing qualitative studies that have examined typically-developing students' views of inclusive education (i.e. the policy of teaching students with special educational needs in mainstream settings). Guidelines from the Centre for Reviews and Dissemination were followed, outlining the criteria by which journal articles were identified and critically appraised. Narrative Synthesis was used to summarize findings across studies. Fourteen studies met the review's inclusion criteria and were subjected to quality assessment. Analysis revealed that studies were of variable quality: three were of "good" methodological quality, seven of "medium" quality, and four of "poor" quality. With respect to findings, three overarching themes emerged: students expressed mostly negative attitudes towards peers with disabilities; were confused by the principles and practices of inclusive education; and made a number of recommendations for improving its future provision. A vital determinant of the success of inclusive education is the extent to which it is embraced by typically-developing students. Of concern, this review highlights that students tend not to understand inclusive education, and that this can breed hostility towards it. More qualitative research of high methodological quality is needed in this area. Implications for Rehabilitation Typically-developing students are key to the successful implementation of inclusive education. This review shows that most tend not to understand it, and can react by engaging in avoidance and/or targeted bullying of peers who receive additional support. Schools urgently need to provide teaching about inclusive education, and increase opportunities for contact between students who do and do not receive support (e.g. cooperative learning).

  18. A Graduate Student's Experience and Perspective on a Student-Teacher-Researcher Partnership (United States)

    Bostic, J.; Stylinski, C.; Doty, C.


    Teachers and their K-12 students lack firsthand experience in science research and often harbor misconceptions about science practices and the nature of science. To address this challenge, the NOAA-funded Student-Teacher-Researcher (STAR) partnership that provides rural high school students with authentic research experiences investigating the amount and sources of nitrate in schoolyard runoff. Teachers received training, guiding curricular materials aligned with NGSS and in-classroom support. With a focus on evidence-based reasoning skills, students actively participate in the research process through sample collection, data analysis, and an in-person discussion of conclusions and implications with our scientist team. As a member of this team, I assisted with refining the study design, analyzing nitrate isotope runoff samples, and sharing insights and feedback with students during the in-person discussion session. Assessment results indicate student gained an understanding of nitrate pollution and of science practices. As a graduate student, young scientist, and possessor of a B.S. in Science Education, I already recognized the value of involving K-12 students and teachers in authentic research experiences, as these experiences expose students to the nature of science while also improving content knowledge. During the STAR partnership, I learned firsthand some of the obstacles presented during outreach involving partnerships between a research institution and schools, such as inflexibility of school scheduling and the need for flexibility with research questions requiring complex lab analysis. Additionally, I discovered the challenge of working systemically across a school district, which can have broad impact but limit student experiences. Highlights of my experience included interactions with students and teachers, especially when students have unexpected answers to my questions, providing novel explanations for patterns observed in the data. Despite the

  19. Student-generated illustrations and written narratives of biological science concepts: The effect on community college life science students' achievement in and attitudes toward science (United States)

    Harvey, Robert Christopher

    The purpose of this study was to determine the effects of two conceptually based instructional strategies on science achievement and attitudes of community college biological science students. The sample consisted of 277 students enrolled in General Biology 1, Microbiology, and Human Anatomy and Physiology 1. Control students were comprised of intact classes from the 2005 Spring semester; treatment students from the 2005 Fall semester were randomly assigned to one of two groups within each course: written narrative (WN) and illustration (IL). WN students prepared in-class written narratives related to cell theory and metabolism, which were taught in all three courses. IL students prepared in-class illustrations of the same concepts. Control students received traditional lecture/lab during the entire class period and neither wrote in-class descriptions nor prepared in-class illustrations of the targeted concepts. All groups were equivalent on age, gender, ethnicity, GPA, and number of college credits earned and were blinded to the study. All interventions occurred in class and no group received more attention or time to complete assignments. A multivariate analysis of covariance (MANCOVA) via multiple regression was the primary statistical strategy used to test the study's hypotheses. The model was valid and statistically significant. Independent follow-up univariate analyses relative to each dependent measure found that no research factor had a significant effect on attitude, but that course-teacher, group membership, and student academic characteristics had a significant effect (p < .05) on achievement: (1) Biology students scored significantly lower in achievement than A&P students; (2) Microbiology students scored significantly higher in achievement than Biology students; (3) Written Narrative students scored significantly higher in achievement than Control students; and (4) GPA had a significant effect on achievement. In addition, given p < .08: (1

  20. Predictive factors of premedical student retention and degree completion within a private undergraduate university (United States)

    Carter, Frances E.

    Undergraduate retention and eventual graduation is of paramount importance to universities globally. Approximately 58% of students who began their college career at a four-year institution with the intention of receiving a bachelor's degree actually received that degree in a 6-year timeframe, according to the National Center for Education Statistics (NCES) annual report The Condition of Education 2009 (Planty, 2009). In certain subgroups of the undergraduate population, this graduation rate is even lower. This dissertation presents research into the academic integration of students in premedical programs subgroup based on Vincent Tinto's Integrationist Model of Student Departure. Pre-entry factors of interest for this study included incoming high school grade point average (GPA), incoming SAT total test scores, while post-matriculation factors included grade in organic chemistry, and the initial calculus course taken. A sample of 519 students from a private coeducational institution in the southeastern United States was examined. A logistic regression was performed to determine the effect of high school GPA, SAT total scores, organic chemistry grades, and calculus-readiness on graduation. A significant regression equation was found. The findings suggest that of the four predictor variables, high school GPA and organic chemistry grade were the only variables that showed significant predictive ability based on a significance level of p < .05. Further research should involve the examination of additional indicators of academic integration as well as information on the social integration of the student. Additionally, institutional leaders should continue to evaluate the premedical curriculum based on potential changes in medical school requirements.

  1. Using Small Group Debates to Actively Engage Students in an Introductory Microbiology Course† (United States)

    Shaw, Joyce A.


    Debates stimulate critical thinking and can be a highly effective way to actively engage students in the classroom. This paper describes a small group debate format in which groups of four to six students debated preassigned topics in microbiology in front of the rest of the class. Rapid advancements in science, especially in microbiology, provide the scaffolding for students to locate and share evidence-based information from a plethora of complex and often conflicting sources. Student-generated debate presentations can be a welcome respite from the lecture format. Debates were scheduled throughout the course to coincide with topics being covered. Questionnaires distributed immediately after each debate revealed that the debates were well received by students and were effective in changing student attitudes and misconceptions. Debate preparation provided students the opportunity to gain proficiency in accessing information from electronic databases, to use resources from professional organizations, and to synthesize and analyze information. In addition, the debate process gave students experience in developing oral communication skills. PMID:23653803

  2. Overcoming the Challenges of BeiDou Receiver Implementation

    Directory of Open Access Journals (Sweden)

    Mohammad Zahidul H. Bhuiyan


    Full Text Available Global Navigation Satellite System (GNSS-based positioning is experiencing rapid changes. The existing GPS and the GLONASS systems are being modernized to better serve the current challenging applications under harsh signal conditions. These modernizations include increasing the number of transmission frequencies and changes to the signal components. In addition, the Chinese BeiDou Navigation Satellite system (BDS and the European Galileo are currently under development for global operation. Therefore, in view of these new upcoming systems the research and development of GNSS receivers has been experiencing a new upsurge. In this article, the authors discuss the main functionalities of a GNSS receiver in view of BDS. While describing the main functionalities of a software-defined BeiDou receiver, the authors also highlight the similarities and differences between the signal characteristics of the BeiDou B1 open service signal and the legacy GPS L1 C/A signal, as in general they both exhibit similar characteristics. In addition, the authors implement a novel acquisition technique for long coherent integration in the presence of NH code modulation in BeiDou D1 signal. Furthermore, a simple phase-preserved coherent integration based acquisition scheme is implemented for BeiDou GEO satellite acquisition. Apart from the above BeiDou-specific implementations, a novel Carrier-to-Noise-density ratio estimation technique is also implemented in the software receiver, which does not necessarily require bit synchronization prior to estimation. Finally, the authors present a BeiDou-only position fix with the implemented software-defined BeiDou receiver considering all three satellite constellations from BDS. In addition, a true multi-GNSS position fix with GPS and BDS systems is also presented while comparing their performances for a static stand-alone code phase-based positioning.

  6. Using Space Science to Excite Hispanic Students in STEM (United States)

    Reiff, P. H.; Galindo, C.; Garcia, J.; Morris, P. A.; Allen, J. S.


    Over the past ten years, NASA and its cosponsors have held an annual "NASA Space Science Day" at the University of Texas at Brownsville. The event is held over two days, with the Friday evening program featuring a space scientist or astronaut, this year Joe Acaba, giving a public lecture (plus a free planetarium show). The Saturday event starts with a keynote speech from the same speaker. Then the students circulate among six or seven hands-on workshops, plus a scheduled trip to the "Demo room" where NASA missions show their materials, and a planetarium show in the Discovery Dome. The students, 4th through 8th graders, are drawn from schools all across south Texas, and have included students coming as far as Zapata, with a four-hour bus ride each way. Over the ten years of the program, more than 5000 students have been reached. Most of the hands-on activities are led by undergraduate student mentors. The university students (42 in 2013) received science and engineering content and mentor training on the activities at Johnson Space Center before the January event. In addition, an additional 40 local high school students helped with activities and with escorting each group of students from one activity station to the next. The program has been so successful that students have "graduated" from participant, to volunteer, and now to University student mentor. Most of the mentors go on to complete a degree in a STEM discipline, and many have gone on to graduate school. Thus the mentors not only help with the program, they are beneficiaries as well. The program is being expanded to reach other underserved communities around the US, with its first "expansion" event held in Utah in 2011.; Puerto Rican Astronaut Joe Acaba and the Discovery Dome were two of the highlights for the students.

  8. Self-assessment of ergonomics amongst dental students utilising photography: RCT. (United States)

    Partido, B B; Wright, B M


    Dental professionals are at high risk of musculoskeletal disorders (MSDs) due to static working positions for extended periods of time. Musculoskeletal pain has been identified as early as during their entry-level dental education. The purpose of this study was to determine whether feedback involving photography and self-assessment would improve ergonomic scores and the accuracy of ergonomic self-assessments amongst dental students. The study involved a randomised control design of 135 dental students. At weeks 1 and 4, participants were photographed, and at weeks 1 through 4, participants completed ergonomic self-evaluations, using a Modified-Dental Operator Posture Assessment Instrument (M-DOPAI). During weeks 2 and 3, participants in the training group were photographed and used those photographs to complete ergonomic self-assessments. All participants' pre-training and post-training photographs were evaluated for ergonomic scores by two raters. A mixed-design ANOVA of ergonomic scores revealed that ergonomic scores improved for all students who received the ergonomics training (F(1,254)=17.41, P < .001). In addition, a mixed-design ANOVA of kappa coefficient values between student and rater scores revealed that the accuracy of self-assessments improved for all students who received the ergonomics training (F(1,127)=6.33, P < .05). The use of photographs and self-assessment provides dental and dental hygiene educators with a pragmatic method to improve self-assessment skills, increase student awareness of any postural deviations from ideal and improve musculoskeletal health. © 2018 John Wiley & Sons A/S.

  10. Schema building profiles among elementary school students in solving problems related to operations of addition to fractions on the basis of mathematic abilities (United States)

    Gembong, S.; Suwarsono, S. T.; Prabowo


    Schema in the current study refers to a set of action, process, object and other schemas already possessed to build an individual’s ways of thinking to solve a given problem. The current study aims to investigate the schemas built among elementary school students in solving problems related to operations of addition to fractions. The analyses of the schema building were done qualitatively on the basis of the analytical framework of the APOS theory (Action, Process, Object, and Schema). Findings show that the schemas built on students of high and middle ability indicate the following. In the action stage, students were able to add two fractions by way of drawing a picture or procedural way. In the Stage of process, they could add two and three fractions. In the stage of object, they could explain the steps of adding two fractions and change a fraction into addition of fractions. In the last stage, schema, they could add fractions by relating them to another schema they have possessed i.e. the least common multiple. Those of high and middle mathematic abilities showed that their schema building in solving problems related to operations odd addition to fractions worked in line with the framework of the APOS theory. Those of low mathematic ability, however, showed that their schema on each stage did not work properly.

  13. Communication Skills in Dental Students: New Data Regarding Retention and Generalization of Training Effects. (United States)

    Broder, Hillary L; Janal, Malvin; Mitnick, Danielle M; Rodriguez, Jasmine Y; Sischo, Lacey


    Previous studies have shown that a communications program using patient instructors (PIs) facilitates data-gathering and interpersonal skills of third-year dental students. The aim of this study was to address the question of whether those skills are retained into the students' fourth year and generalized from the classroom to the clinic. In the formative training phase, three cohorts of D3 students (N=1,038) at one dental school received instruction regarding effective patient-doctor communication; interviewed three PIs and received PI feedback; and participated in a reflective seminar with a behavioral science instructor. In the follow-up competency phase, fourth-year students performed two new patient interviews in the clinic that were observed and evaluated by clinical dental faculty members trained in communications. Mean scores on a standardized communications rating scale and data-gathering assessment were compared over training and follow-up sessions and between cohorts with a linear mixed model. The analysis showed that the third-year students' mean communication and data-gathering scores increased with each additional encounter with a PI (pcommunication scores were not only maintained but increased during the fourth-year follow-up competency evaluations (pcommunications curriculum, prior instruction facilitated the students' clinical communication performance at baseline (pCommunications program improved students' data-gathering and interpersonal skills. Those skills were maintained and generalized through completion of the D4 students' summative competency performance in a clinical setting.

We have completed many of the individual student research projects: 2 PhD students have finished, and 4 are still working towards their PhD degree. 4 MS students have finished, and 2 are still working towards their MS degree, one of which is due to finish this April. In addition, 4 undergraduate student projects have been completed, and one is to be completed this April. These projects were supervised by 7 faculty members and an Advisory/Review Panel. Our students and faculty have presented their work at national or international conferences and have submitted several journal publications. Three of our graduate students (Keith Martin, Dan Leonard and Hosein Foroutan) have received HRF Fellowships during the course of this project. All of the remaining students are anticipated to be graduated by the end of Fall Semester 2014. All of the tasks for this project will have been completed once all the students have been graduated, although it will be another year or two until all the journal publications have been finalized based on the work performed as part of this DOE Hydropower project.

  15. Exploring assistive technology and post-school outcomes for students with severe disabilities. (United States)

    Bouck, Emily C; Flanagan, Sara M


    This study sought to understand the extent to which students with severe disabilities receive assistive technology in school and out-of-school, and the relationship between receipt of assistive technology in school and post-school outcomes for these students. This study was a secondary analysis of the National Longitudinal Transition Study-2 (NLTS2) from the USA. To analyze the data in this correlational study, researchers conducted frequency distributions, Chi Square Tests of Associations, significance tests and logistic regressions. The main results suggest (a) receipt of assistive technology in school varied greatly by disability identification; (b) receipt of assistive technology post-school also varied by disability identification, but receipt was generally lower; and (c) few statistically significant post-school outcome differences existed between students who received assistive technology and those who did not. An under-utilization of assistive technology exists in practice in the USA for students with severe disabilities. Implications for Rehabilitation An under-utilization of assistive technology for secondary students and adults with severe disabilities likely exists. A need exists for improved collaboration between professionals in rehabilitation and professionals in schools to ensure continuation of needed services or aids, such as assistive technology. Additional research is needed to better understand the adult life (or post-school) outcomes of individuals with severe disabilities, factors from PK-12 schooling or post-school services that positively and negative impact those outcomes.

  16. Student science enrichment training program

    Energy Technology Data Exchange (ETDEWEB)

    Sandhu, S.S.


    This is a report on the Student Science Enrichment Training Program, with special emphasis on chemical and computer science fields. The residential summer session was held at the campus of Claflin College, Orangeburg, SC, for six weeks during 1993 summer, to run concomitantly with the college`s summer school. Fifty participants selected for this program, included high school sophomores, juniors and seniors. The students came from rural South Carolina and adjoining states which, presently, have limited science and computer science facilities. The program focused on high ability minority students, with high potential for science engineering and mathematical careers. The major objective was to increase the pool of well qualified college entering minority students who would elect to go into science, engineering and mathematical careers. The Division of Natural Sciences and Mathematics and engineering at Claflin College received major benefits from this program as it helped them to expand the Departments of Chemistry, Engineering, Mathematics and Computer Science as a result of additional enrollment. It also established an expanded pool of well qualified minority science and mathematics graduates, which were recruited by the federal agencies and private corporations, visiting Claflin College Campus. Department of Energy`s relationship with Claflin College increased the public awareness of energy related job opportunities in the public and private sectors.

  18. Impact of tailored feedback in assessment of communication skills for medical students. (United States)

    Uhm, Seilin; Lee, Gui H; Jin, Jeong K; Bak, Yong I; Jeoung, Yeon O; Kim, Chan W


    Finding out the effective ways of teaching and assessing communication skills remain a challenging part of medication education. This study aims at exploring the usefulness and effectiveness of having additional feedback using qualitative analysis in assessment of communication skills in undergraduate medical training. We also determined the possibilities of using qualitative analysis in developing tailored strategies for improvement in communication skills training. This study was carried out on medical students (n=87) undergoing their final year clinical performance examination on communication skills using standardized patient by video-recording and transcribing their performances. Video-recordings of 26 students were randomly selected for qualitative analysis, and additional feedback was provided. We assessed the level of acceptance of communication skills scores between the study and nonstudy group and within the study group, before and after receiving feedback based on qualitative analysis. There was a statistically significant increase in the level of acceptance of feedback after delivering additional feedback using qualitative analysis, where the percentage of agreement with feedback increased from 15.4 to 80.8% (pskills assessment gives essential information for medical students to learn and self-reflect, which could potentially lead to improved communication skills. As evident from our study, feedback becomes more meaningful and effective with additional feedback using qualitative analysis.

  19. Personal monitoring and assessment of doses received by radiation workers

    Swindon, T.N.; Morris, N.D.


    The Personal Radiation Monitoring Service operated by the Australian Radiation Laboratory is outlined and the types of monitors used for assessment of doses received by radiation workers are described. The distribution of doses received by radiation workers in different occupational categories is determined. From these distributions, the average doses received have been assessed and the maximum likely additional increase in cancer deaths in Australia as a result of occupational exposure estimated. This increase is shown to be very small. There is, however, a considerable spread of doses received by individuals within occupational groups

  20. The office of student wellness: innovating to improve student mental health. (United States)

    Seritan, Andreea L; Rai, Gurmeet; Servis, Mark; Pomeroy, Claire


    Despite increasing mental health needs among medical students, few models for effective preventive student wellness programs exist. This paper describes a novel approach developed at the University of California (UC) Davis School of Medicine: the Office of Student Wellness (OSW). Improved access and mental health service utilization have been documented, with over half of all students receiving support and clinical care. UC Davis student satisfaction mean scores on the Association of American Medical Colleges Graduation Questionnaire wellness questions have reached or exceeded national average over the last 4 years, since the OSW was founded. This program may serve as a blueprint for other medical schools in developing effective student wellness programs.

  1. Increasing student success in STEM through geosciences based GIS curriculum, interdisciplinary project based learning, and specialized STEM student services (United States)

    Cheung, W.


    Under the auspices of the National Science Foundation's Advanced Technological Education Grant and the Department of Education's Title V/HSI Grant, Palomar College students from a variety of disciplines have not only been exposed to the high growth field of geospatial technologies, but have also been exposed to the geosciences and regional environmental issues in their GIS courses. By integrating introductory Physical Geography topics such as liquefaction, subsidence, ozone depletion, plate tectonics, and coastal processes in the introductory GIS curriculum, GIS students from fields ranging from Archaeology to Zoology were exposed to basic geosciences theories in a series of hands-on interactive exercises, while gaining competency in geospatial technologies. Additionally, as students undertake interdisciplinary service learning projects under the supervision of experts in the private, governmental, and nonprofit sectors, students were introduced to the STEM workplace, forged invaluable professional connections, applied their classroom knowledge to advance research (e.g. analyzing migration patterns of cephalopod), and analyzed regional environmental issues (e.g. distribution of invasive plants in state natural preserves). In order to further the retention and completion of students in GIS, Earth Science, and other STEM courses, a STEM Student Learning Center was constructed, whereby students can receive services such as supplemental instruction, walk-in tutoring, STEM counseling and transfer advising, as well as faculty and peer mentoring.

  2. Design of the Acoustic Signal Receiving Unit of Acoustic Telemetry While Drilling

    Li Zhigang


    Full Text Available Signal receiving unit is one of the core units of the acoustic telemetry system. A new type of acoustic signal receiving unit is designed to solve problems of the existing devices. The unit is a short joint in whole. It not only can receive all the acoustic signals transmitted along the drill string, without losing any signal, but will not bring additional vibration and interference. In addition, the structure of the amplitude transformer is designed, which can amplify the signal amplitude and improve the receiving efficiency. The design of the wireless communication module makes the whole device can be used in normal drilling process when the drill string is rotating. So, it does not interfere with the normal drilling operation.

  3. Influence of learning style on instructional multimedia effects on graduate student cognitive and psychomotor performance. (United States)

    Smith, A Russell; Cavanaugh, Catherine; Jones, Joyce; Venn, John; Wilson, William


    Learning outcomes may improve in graduate healthcare students when attention is given to individual learning styles. Interactive multimedia is one tool shown to increase success in meeting the needs of diverse learners. The purpose of this study was to examine the effect of learning style and type of instruction on physical therapy students' cognitive and psychomotor performance. Participants were obtained by a sample of convenience with students recruited from two physical therapy programs. Twenty-seven students volunteered to participate from Program 1. Twenty-three students volunteered to participate from Program 2. Gregorc learning styles were identified through completion of the Gregorc Style Delineator. Students were randomly assigned to one of two instructional strategies: 1) instructional CD or 2) live demonstration. Differences in cognitive or psychomotor performance following instructional multimedia based on learning style were not demonstrated in this study. Written examination scores improved with both instructional strategies demonstrating no differences between the strategies. Practical examination ankle scores were significantly higher in participants receiving CD instruction than in participants receiving live presentation. Learning style did not significantly affect this improvement. Program 2 performed significantly better on written knee and practical knee and ankle examinations. Learning style had no significant effect on student performance following instruction in clinical skills via interactive multimedia. Future research may include additional measurement instruments assessing other models of learning styles and possible interaction of learning style and instructional strategy on students over longer periods of time, such as a semester or an entire curriculum.

  4. Sexting and sexual behavior among middle school students. (United States)

    Rice, Eric; Gibbs, Jeremy; Winetrobe, Hailey; Rhoades, Harmony; Plant, Aaron; Montoya, Jorge; Kordic, Timothy


    It is unknown if "sexting" (i.e., sending/receiving sexually explicit cell phone text or picture messages) is associated with sexual activity and sexual risk behavior among early adolescents, as has been found for high school students. To date, no published data have examined these relationships exclusively among a probability sample of middle school students. A probability sample of 1285 students was collected alongside the 2012 Youth Risk Behavior Survey in Los Angeles middle schools. Logistic regressions assessed the correlates of sexting behavior and associations between sexting and sexual activity and risk behavior (ie, unprotected sex). Twenty percent of students with text-capable cell phone access reported receiving a sext and 5% reported sending a sext. Students who text at least 100 times per day were more likely to report both receiving (odds ratio [OR]: 2.4) and sending (OR: 4.5) sexts and to be sexually active (OR: 4.1). Students who sent sexts (OR: 3.2) and students who received sexts (OR: 7.0) were more likely to report sexual activity. Compared with not being sexually active, excessive texting and receiving sexts were associated with both unprotected sex (ORs: 4.7 and 12.1, respectively) and with condom use (ORs: 3.7 and 5.5, respectively). Because early sexual debut is correlated with higher rates of sexually transmitted infections and teen pregnancies, pediatricians should discuss sexting with young adolescents because this may facilitate conversations about sexually transmitted infection and pregnancy prevention. Sexting and associated risks should be considered for inclusion in middle school sex education curricula. Copyright © 2014 by the American Academy of Pediatrics.

  5. Learning the Students' Names: Does it Matter?

    Jørgensen, Anker Helms


    on the effect of learning the students' names are sparse. Against this background, this paper reports on a method for learning all the students' names and two studies of the effect, based on my use of the method in my teaching. The two survey studies were carried in 2011 and in 2014. A survey was in the first...... sent to 50 students and I received 18 answers (38%). The second survey was sent to 86 students and I received 48 answers (56%). These figures provides a good indication.The answers showed a marked positive effect: the students felt welcome, accepted and respected; the learning environment was more......A key factor in successful teaching and learning is the relationship between the students and the teacher. A simple approach nurturing this relationship is learning the students' names. This is often suggested in the literature, but seems rarely practised. Substantial reports in the literature...

  6. Endotracheal intubation skill acquisition by medical students

    Full Text Available During the course of their training, medical students may receive introductory experience with advanced resuscitation skills. Endotracheal intubation (ETI – the insertion of a breathing tube into the trachea is an example of an important advanced resuscitation intervention. Only limited data characterize clinical ETI skill acquisition by medical students. We sought to characterize medical student acquisition of ETI procedural skill.11Presented as a poster discussion on 17 October 2007 at the annual meeting of the American Society of Anesthesiologists in San Francisco, CA.The study included third-year medical students participating in a required anesthesiology clerkship. Students performed ETI on operating room patients under the supervision of attending anesthesiologists. Students reported clinical details of each ETI effort, including patient age, sex, Mallampati score, number of direct laryngoscopies and ETI success. Using mixed-effects regression, we characterized the adjusted association between ETI success and cumulative ETI experience.ETI was attempted by 178 students on 1,646 patients (range 1–23 patients per student; median 9 patients per student, IQR 6–12. Overall ETI success was 75.0% (95% CI 72.9–77.1%. Adjusted for patient age, sex, Mallampati score and number of laryngoscopies, the odds of ETI success improved with cumulative ETI encounters (odds ratio 1.09 per additional ETI encounter; 95% CI 1.04–1.14. Students required at least 17 ETI encounters to achieve 90% predicted ETI success.In this series medical student ETI proficiency was associated with cumulative clinical procedural experience. Clinical experience may provide a viable strategy for fostering medical student procedural skills.

    In the following study a complete balance over the REFOS receiver module, mounted on the tower power plant CESA-1 at the Plataforma Solar de Almeria (PSA), is carried out. Additionally an error inspection of the various measurement techniques used in the REFOS project is made. Especially the flux measurement system Prohermes that is used to determine the total entry power of the receiver module and known as a major error source is analysed in detail. Simulations and experiments on the particular instruments are used to determine and quantify possible error sources. After discovering the origin of the errors they are reduced and included in the error calculation. the ultimate result is presented as an overall efficiency of the receiver module in dependence on the flux density at the receiver module's entry plane and the receiver operating temperature.

  9. University-Industry Interaction: Reserach and Career Opportunities - Good for Industry, Faculty and Students (United States)

    Schneider, John


    Industry sponsorship of research at universities is growing and becoming more important as funding resources change. In addition, re-engineering at industries has forced them to review how and what they sponsor at universities. Well thought out and understood "partnerships" between companies and universities can be good for everyone. Students receive scholarships, research opportunities, exposure to industry life and career/job opportunities. Faculty receive funds for their research, exposure to real-world problems, equipment, consulting opportunities and more. . Universities receive funds for research, scholarships, etc. In addition, there are opportunities for royalties and donations that help everyone. . The public gains trained students, research advances that lead to better and lower cost products, and economic growth. A concern faculty often express is that they would have to do "applied" and not leading edge research. It is true that industry will not fund "any" research; they want to support research that solves their current needs or could lead to break-throughs in products they can commercialize. Many industrial scientists counter academic concerns by stating that doing practical research can and usually is fundamental and discovery oriented. University-Industry collaboration research has been good for all and can continue to be so. Leading organizations such as the National Science Foundation and the Council on Competitiveness are stressing the need for collaborative partnerships. Universities are creating education programs that bring the basic sciences in contact with the applied world.

  10. Does the inclusion of 'professional development' teaching improve medical students' communication skills? (United States)


    Background This study investigated whether the introduction of professional development teaching in the first two years of a medical course improved students' observed communication skills with simulated patients. Students' observed communication skills were related to patient-centred attitudes, confidence in communicating with patients and performance in later clinical examinations. Methods Eighty-two medical students from two consecutive cohorts at a UK medical school completed two videoed consultations with a simulated patient: one at the beginning of year 1 and one at the end of year 2. Group 1 (n = 35) received a traditional pre-clinical curriculum. Group 2 (n = 47) received a curriculum that included communication skills training integrated into a 'professional development' vertical module. Videoed consultations were rated using the Evans Interview Rating Scale by communication skills tutors. A subset of 27% were double-coded. Inter-rater reliability is reported. Results Students who had received the professional development teaching achieved higher ratings for use of silence, not interrupting the patient, and keeping the discussion relevant compared to students receiving the traditional curriculum. Patient-centred attitudes were not related to observed communication. Students who were less nervous and felt they knew how to listen were rated as better communicators. Students receiving the traditional curriculum and who had been rated as better communicators when they entered medical school performed less well in the final year clinical examination. Conclusions Students receiving the professional development training showed significant improvements in certain communication skills, but students in both cohorts improved over time. The lack of a relationship between observed communication skills and patient-centred attitudes may be a reflection of students' inexperience in working with patients, resulting in 'patient-centredness' being an abstract concept

  12. A randomised controlled trial of sensory awareness training and additional motor practice for learning scalpel skills in podiatry students. (United States)

    Causby, Ryan S; McDonnell, Michelle N; Reed, Lloyd; Hillier, Susan L


    The process of using a scalpel, like all other motor activities, is dependent upon the successful integration of afferent (sensory), cognitive and efferent (motor) processes. During learning of these skills, even if motor practice is carefully monitored there is still an inherent risk involved. It is also possible that this strategy could reinforce high levels of anxiety experienced by the student and affect student self-efficacy, causing detrimental effects on motor learning. An alternative training strategy could be through targeting sensory rather than motor processes. Second year podiatry students who were about to commence learning scalpel skills were recruited. Participants were randomly allocated into sensory awareness training (Sensory), additional motor practice (Motor) or usual teaching only (Control) groups. Participants were then evaluated on psychological measures (Intrinsic Motivation Inventory) and dexterity measures (Purdue Pegboard, Grooved Pegboard Test and a grip-lift task). A total of 44 participants were included in the study. There were no baseline differences or significant differences between the three groups over time on the Perceived Competence, Effort/ Importance or Pressure/ Tension, psychological measures. All groups showed a significant increase in Perceived Competence over time (F 1,41  = 13.796, p = 0.001). Only one variable for the grip-lift task (Preload Duration for the non-dominant hand) showed a significant difference over time between the groups (F 2,41  = 3.280, p = 0.038), specifically, Motor and Control groups. The use of sensory awareness training, or additional motor practice did not provide a more effective alternative compared with usual teaching. Further research may be warranted using more engaged training, provision of supervision and greater participant numbers.

  13. Enhancements to the hybrid pressurized air receiver (HPAR) concept in the SUNDISC cycle (United States)

    Heller, Lukas; Hoffmann, Jaap


    A dual-pressure air receiver has previously been proposed as part of a hybrid receiver system preheating pressurized air in a solarized gas turbine and providing hot non-pressurized air to power the bottoming cycle of a combined cycle CSP plant. The receiver, based on a bundle of metallic tubular absorbers, was found to not be able to provide the non-pressurized air at the required temperature. Three enhancements to the basic design are presented and thermally modeled: (a) Finned absorber tubes to increase the convective heat transfer, (b) quartz glass elements to alleviate convective losses and improve the flow inside the tube bundle as well as (c) additional absorber elements behind the tube bundle. It could be shown that finned absorber tubes as well as the additional absorber elements have potential to improve the thermal performance of the receiver while a quartz glass window and flow-enhancing quartz elements could be indispensable additions to either of the other enhancements.

  15. Effect of two Howard Hughes Medical Institute research training programs for medical students on the likelihood of pursuing research careers. (United States)

    Fang, Di; Meyer, Roger E


    To assess the effect of Howard Hughes Medical Institute's (HHMI) two one-year research training programs for medical students on the awardees' research careers. Awardees of the HHMI Cloister Program who graduated between 1987 and 1995 and awardees of the HHMI Medical Fellows Program who graduated between 1991 and 1995 were compared with unsuccessful applicants to the programs and MD-PhD students who graduated during the same periods. Logistic regression analyses were conducted to assess research career outcomes while controlling for academic and demographic variables that could affect selection to the programs. Participation in both HHMI programs increased the likelihood of receiving National Institutes of Health postdoctoral support. Participation in the Cloister Program also increased the likelihood of receiving a faculty appointment with research responsibility at a medical school. In addition, awardees of the Medical Fellows Program were not significantly less likely than Medical Scientist Training Program (MSTP) and non-MSTP MD-PhD program participants to receive a National Institutes of Health postdoctoral award, and awardees of the Cloister Program were not significantly less likely than non-MSTP MD-PhD students to receive a faculty appointment with research responsibility. Women and underrepresented minority students were proportionally represented among awardees of the two HHMI programs whereas they were relatively underrepresented in MD-PhD programs. The one-year intensive research training supported by the HHMI training programs appears to provide an effective imprinting experience on medical students' research careers and to be an attractive strategy for training physician-scientists.

  17. "May I help you?" – Evaluation of the new student service at the reception desk during the clinical courses at the Department of Operative Dentistry and Periodontology as a part of a longitudinal curriculum of social and communicative competences for dental students

    Directory of Open Access Journals (Sweden)

    Lichtenstein, Nora


    Full Text Available Objectives: Since 2009, the University of Cologne has been developing a longitudinal curriculum for teaching social and communicative skills to dental students (LSK-Dent based on the recommendations of the Association for Dental Education in Europe (ADEE. As a part of this curriculum it was considered to develop a reception service in the undergraduate treatment courses of the Department of Operative Dentistry and Periodontology involving the organizational and administrative handling of the patients by the students. Students should gain an insight into everyday practice and the reception service should function as a learning environment for social und communicative competences. This article introduces the LSK-Dent project, the implementation of the reception service and presents initial evaluation results.Methods: Patients (n=575 and students (n=53 filled out a questionnaire. Additionally, four semi-structured interviews with students were conducted.Results: The reception service was successfully implemented and endorsed by the students. First indications suggest that the reception service was well received by students as a learning environment for social und communicative competences and viewed as an opportunity to gain an insight into everyday practice.Conclusion: The reception service is an innovative addition to the treatment courses and an example for transforming an already existing reality in a course into a new learning environment for students. To what extent the implementation of reflexive elements can increase the subjectively perceived additional benefit by students, has to be addressed in further studies.

  18. Smooth time-dependent receiver operating characteristic curve estimators. (United States)

    Martínez-Camblor, Pablo; Pardo-Fernández, Juan Carlos


    The receiver operating characteristic curve is a popular graphical method often used to study the diagnostic capacity of continuous (bio)markers. When the considered outcome is a time-dependent variable, two main extensions have been proposed: the cumulative/dynamic receiver operating characteristic curve and the incident/dynamic receiver operating characteristic curve. In both cases, the main problem for developing appropriate estimators is the estimation of the joint distribution of the variables time-to-event and marker. As usual, different approximations lead to different estimators. In this article, the authors explore the use of a bivariate kernel density estimator which accounts for censored observations in the sample and produces smooth estimators of the time-dependent receiver operating characteristic curves. The performance of the resulting cumulative/dynamic and incident/dynamic receiver operating characteristic curves is studied by means of Monte Carlo simulations. Additionally, the influence of the choice of the required smoothing parameters is explored. Finally, two real-applications are considered. An R package is also provided as a complement to this article.

  19. Graphene integrated circuits: new prospects towards receiver realisation. (United States)

    Saeed, Mohamed; Hamed, Ahmed; Wang, Zhenxing; Shaygan, Mehrdad; Neumaier, Daniel; Negra, Renato


    This work demonstrates a design approach which enables the fabrication of fully integrated radio frequency (RF) and millimetre-wave frequency direct-conversion graphene receivers by adapting the frontend architecture to exploit the state-of-the-art performance of the recently reported wafer-scale CVD metal-insulator-graphene (MIG) diodes. As a proof-of-concept, we built a fully integrated microwave receiver in the frequency range 2.1-2.7 GHz employing the strong nonlinearity and the high responsivity of MIG diodes to successfully receive and demodulate complex, digitally modulated communication signals at 2.45 GHz. In addition, the fabricated receiver uses zero-biased MIG diodes and consumes zero dc power. With the flexibility to be fabricated on different substrates, the prototype receiver frontend is fabricated on a low-cost, glass substrate utilising a custom-developed MMIC process backend which enables the high performance of passive components. The measured performance of the prototype makes it suitable for Internet-of-Things (IoT) and Radio Frequency Identification (RFID) systems for medical and communication applications.

  3. Student Learning Strategy and Soft-skill in Clothing Business Management (United States)

    Ampera, D.


    Clothing Business Management course is a subject delivering knowledge and skills about how to manage clothing business. This course requires students’ ethics, leadership, commitment, toughness, honesty, and the ability to take initiative, argue logically, and work together. However, students are not fully efficient in managing a business during practical task. The purpose of the study is to investigate: (1) the differences of students’ learning achievement between those receiving gradual and conventional learning strategy, (2)the effect of interactions between learning strategy and soft skills toward students learning achievement, (3) the differences of learning achievement of high soft skills students who receive gradual and conventional learning strategy, (4) the differences of learning achievement of low soft skills students who receive gradual and conventional learning strategy. The 2x2 treatment-by-level experimental study was carried out in Dressmaking Study Program. The result proved significantly that, overall, differences of students learning achievement exist, except of low soft skills students.

  6. Effect of Wind Flow on Convective Heat Losses from Scheffler Solar Concentrator Receivers (United States)

    Nene, Anita Arvind; Ramachandran, S.; Suyambazhahan, S.


    Receiver is an important element of solar concentrator system. In a Scheffler concentrator, solar rays get concentrated at focus of parabolic dish. While radiation losses are more predictable and calculable since strongly related to receiver temperature, convective looses are difficult to estimate in view of additional factors such as wind flow direction, speed, receiver geometry, prior to current work. Experimental investigation was carried out on two geometries of receiver namely cylindrical and conical with 2.7 m2 Scheffler to find optimum condition of tilt to provide best efficiency. Experimental results showed that as compared to cylindrical receiver, conical receiver gave maximum efficiency at 45° tilt angle. However effect of additional factors like wind speed, wind direction on especially convective losses could not be separately seen. The current work was undertaken to investigate further the same two geometries using computation fluid dynamics using FLUENT to compute convective losses considering all variables such at tilt angle of receiver, wind velocity and wind direction. For cylindrical receiver, directional heat transfer coefficient (HTC) is remarkably high to tilt condition meaning this geometry is critical to tilt leading to higher convective heat losses. For conical receiver, directional average HTC is remarkably less to tilt condition leading to lower convective heat loss.

  10. Heat receivers for solar dynamic space power systems (United States)

    Perez-Davis, Marla Esther

    A review of state-of-the-art technology is presented and discussed for phase change materials. Some of the advanced solar dynamic designs developed as part of the Advanced Heat Receiver Conceptual Design Study performed for LeRC are discussed. The heat receivers are analyzed and several recommendations are proposed, including two new concepts. The first concept evaluated the effect of tube geometries inside the heat receiver. It was found that a triangular configuration would provide better heat transfer to the working fluid, although not necessarily with a reduction in receiver size. A sensible heat receiver considered in this study uses vapor grown graphite fiber-carbon (VGCF/C) composite as the thermal storage media and was designed for a 7 kW Brayton engine. The proposed heat receiver stores the required energy to power the system during eclipse in the VGCF/C composite. The heat receiver analysis was conducted through the Systems Improved Numerical Differencing Analyzer and Fluid Integrator (SINDA) software package. The proposed heat receiver compares well with other latent and advanced sensible heat receivers while avoiding the problems associated with latent heat storage salts and liquid metal heat pipes. The weight and size of the system can be optimized by changes in geometry and technology advances for this new material. In addition to the new concepts, the effect of atomic oxygen on several materials is reviewed. A test was conducted for atomic oxygen attack on boron nitride, which experienced a negligible mass loss when exposed to an atomic oxygen fluence of 5 x 10 exp 21 atoms/sq cm. This material could be used to substitute the graphite aperture plate of the heat receiver.

But how about…

  13. Laser polishing of additive manufactured Ti alloys (United States)

    Ma, C. P.; Guan, Y. C.; Zhou, W.


    Laser-based additive manufacturing has attracted much attention as a promising 3D printing method for metallic components in recent years. However, surface roughness of additive manufactured components has been considered as a challenge to achieve high performance. In this work, we demonstrate the capability of fiber laser in polishing rough surface of additive manufactured Ti-based alloys as Ti-6Al-4V and TC11. Both as-received surface and laser-polished surfaces as well as cross-section subsurfaces were analyzed carefully by White-Light Interference, Confocal Microscope, Focus Ion Beam, Scanning Electron Microscopy, Energy Dispersive Spectrometer, and X-ray Diffraction. Results revealed that as-received Ti-based alloys with surface roughness more than 5 μm could be reduce to less than 1 μm through laser polishing process. Moreover, microstructure, microhardness and wear resistance of laser-polished zone was investigated in order to examine the thermal effect of laser polishing processing on the substrate of additive manufactured Ti alloys. This proof-of-concept process has the potential to effectively improve the surface roughness of additive manufactured metallic alloy by local polishing method without damage to the substrate.

  15. Improving student performance in an introductory biology majors course: A social action project in the scholarship of teaching (United States)

    Chambers, Sara Lang Ketchum

    This social action study followed an introductory biology course for a three-year period to determine whether changes in teaching personnel, instructional techniques and reorientation to student-centered learning would impact student performance. The course was redirected from a traditional lecture-laboratory format to one emphasizing active learning inquiry methods. Student retention, achievement, and failure were observed for three years in addition to one year prior, and one year following, the study. The study examined the two semester introductory biology course required of all biology majors and those intending a career in science, medicine or dentistry. During the first semester of the study, the dropout rate decreased from 46% to 21%. Prior to the study, 39% of the students completing the course received a grade of D or F while only 4% received a grade of B or above. During the first semester of the study 14% of the students received a grade of D or F while 46% received a B, B+ or A grade. Similar results were seen in other semesters of the study. A statistical comparison of student retention and performance was carried out using grade data for classes taught by the original faculty, the action study faculty and the post-study faculty. The differences between the original faculty and the action study faculty were statistically significant. Effect size calculations indicated large differences between the action study faculty and the two other faculty groups in terms of student retention, achievement and failure. The results are attributed to both the personnel change and, more significantly, the change in teaching methods and emphasis on student-active learning. Comparison between the pre- and post-study teams showed less dramatic effect sizes than when the action study data were compared with the data from either other team. Nevertheless, the post-study results showed that although the retention rate dropped during the year after the study, the improvement

  16. Evaluation of second-generation central receiver technologies

    International Nuclear Information System (INIS)

    Kolb, G.L.; Chavez, J.M.; Klimas, P.; Meinecke, W.; Becker, M.; Kiera, M.


    This paper summarizes the results of a study performed by the US and Germany to assess the technical and economic potential of central receiver power plants and to identify the necessary research and development (R ampersand D) activities required to reach demonstration and commercialization. Second generation power plant designs, employing molten-salt and volumetric-air receivers, were assessed at the size of 30 and 100 MWe. The study developed a common guideline and used data from previous system tests and studies. The levelized-energy costs for the second generation plants were estimated and found to be competitive with costs from fossil-fueled power plants. Potential for further cost reductions exists if technical improvements can be introduced successfully in the long term. Additionally, the study presents results of plant reliability and uncertainty analyses. Mid- and long-term technical potentials are described, as well as recommendations for the R ampersand D activities needed to reach the goal of large-scale commercialization. The results of this study have already helped direct research in the US and Europe. For example, the favorable potential for these technologies has led to the Solar Two molten-salt project in the US and the TSA volumetric receiver test in Spain. In addition, early analysis conducted within this study indicated that an advanced thermal storage medium was necessary to achieve favorable economics for the air plant. This led to the design of the thermal storage system currently being tested in Spain. In summary, each of the investigated receiver technologies has mid- and long-term potential for improving plant performance and reducing capital and energy costs (resulting in less than 10 cts/kWh given excellent insolation conditions) in an environmentally safe way and largely independent of fossil-fuel prices

  17. E-Mentoring for Doctor of Nursing Practice Students: A Pilot Program. (United States)

    Harris, Robin; Birk, Stefanie B; Sherman, Jan


    The growing number of online Doctor of Nursing Practice (DNP) programs, steady attrition rates, and shortage of faculty created an opportunity to explore the use of distance-mediated mentoring. Twenty first-year DNP Nursing Leadership students were matched with DNP-prepared mentors in a formalized e-mentoring program. The Ideal Mentor Scale was used to determine what students desired most from the mentoring relationship in addition to midpoint and end-of-program surveys. Quantitative analysis revealed mentors and mentees found the relationship to be beneficial (p mentors (92%) noted the program supplied adequate resources, and the majority of students would recommend the program. Having a mentor leads to both mentor- and mentee-perceived benefits. Recommendations include continuing to seek ways to improve the communication and commitment between the mentor and mentee in order to receive reciprocal program benefits.

  18. Tit-For-Tat Strategy for Increasing Medical Student Evaluation Response Rates

    Directory of Open Access Journals (Sweden)

    Matthew G. Malone


    Full Text Available Introducation It is essential for faculty to receive feedback on their teaching for the purpose of improvement as well as promotion. It can be challenging to motivate students to provide feedback to preceptors and fill out evaluation forms when not a clerkship requirement. Furthermore, there is concern that making the evaluations a requirement can compromise the quality of the feedback. The objective of this study was to identify an increase in the number of faculty and resident evaluations completed by students rotating through their Emergency Medicine clerkship following the implementation of a tit-for-tat incentive strategy. Method Prior to the implementation of Tit-for-Tat, students rotating through their emergency medicine clerkship were asked to fill out evaluations of residents and faculty members with whom they worked. These were encouraged but voluntary. Beginning in the 2014–2015 academic year, a tit-for-tat strategy was employed whereby students had to complete a resident or faculty evaluation in order to view the student assessment completed by that resident or faculty preceptor. Results Students submitted 1101 evaluations in the control, with a mean of 3.60 evaluations completed per student and 3.77 evaluations received per preceptor. Following the implementation of tit-for-tat, students submitted 2736 evaluations, with a mean of 8.19 evaluations completed per student and 7.52 evaluations received per preceptor. Both the increase in evaluations completed per student and evaluations received per preceptor were statistically significant with p-value <0.001. Conclusion The tit-for-tat strategy significantly increased the number of evaluations submitted by students rotating through their emergency medicine clerkship. This has served as an effective tool to increase the overall number of evaluations completed, the number of evaluations each instructor received on average and the proportion of students that completed evaluations

  19. An e-learning reproductive health module to support improved student learning and interaction: a prospective interventional study at a medical school in Egypt. (United States)

    Abdelhai, Rehab; Yassin, Sahar; Ahmad, Mohamad F; Fors, Uno G H


    The Public Health (PH) course at the medical college of Cairo University is based on traditional lectures. Large enrollment limits students' discussions and interactions with instructors. Evaluate students' learning outcomes as measured by improved knowledge acquisition and opinions of redesigning the Reproductive Health (RH) section of the PH course into e-learning and assessing e-course utilization. This prospective interventional study started with development of an e-learning course covering the RH section, with visual and interactive emphasis, to satisfy students' diverse learning styles. Two student groups participated in this study. The first group received traditional lecturing, while the second volunteered to enroll in the e-learning course, taking online course quizzes. Both groups answered knowledge and course evaluation questionnaires and were invited to group discussions. Additionally, the first group answered another questionnaire about reasons for non-participation. Students participating in the e-learning course showed significantly better results, than those receiving traditional tutoring. Students who originally shunned the e-course expressed eagerness to access the course before the end of the academic year. Overall, students using the redesigned e-course reported better learning experiences. An online course with interactivities and interaction, can overcome many educational drawbacks of large enrolment classes, enhance student's learning and complement pit-falls of large enrollment traditional tutoring.

Therefore, this study examined how students…

  1. Comparing Two Inquiry Professional Development Interventions in Science on Primary Students' Questioning and Other Inquiry Behaviours (United States)

    Nichols, Kim; Burgh, Gilbert; Kennedy, Callie


    Developing students' skills to pose and respond to questions and actively engage in inquiry behaviours enables students to problem solve and critically engage with learning and society. The aim of this study was to analyse the impact of providing teachers with an intervention in inquiry pedagogy alongside inquiry science curriculum in comparison to an intervention in non-inquiry pedagogy alongside inquiry science curriculum on student questioning and other inquiry behaviours. Teacher participants in the comparison condition received training in four inquiry-based science units and in collaborative strategic reading. The experimental group, the community of inquiry (COI) condition, received training in facilitating a COI in addition to training in the same four inquiry-based science units. This study involved 227 students and 18 teachers in 9 primary schools across Brisbane, Australia. The teachers were randomly allocated by school to one of the two conditions. The study followed the students across years 6 and 7 and students' discourse during small group activities was recorded, transcribed and coded for verbal inquiry behaviours. In the second year of the study, students in the COI condition demonstrated a significantly higher frequency of procedural and substantive higher-order thinking questions and other inquiry behaviours than those in the comparison condition. Implementing a COI within an inquiry science curriculum develops students' questioning and science inquiry behaviours and allows teachers to foster inquiry skills predicated by the Australian Science Curriculum. Provision of inquiry science curriculum resources alone is not sufficient to promote the questioning and other verbal inquiry behaviours predicated by the Australian Science Curriculum.

  2. Testing the Grandchildren's Received Affection Scale using Affection Exchange Theory. (United States)

    Mansson, Daniel H


    The purpose of this study was to test the Grandchildren's Received Affection Scale (GRAS) using Affection Exchange Theory (Floyd, 2006). In accordance with Affection Exchange Theory, it was hypothesized that grandchildren's scores on the Trait Affection Received Scale (i.e., the extent to which individuals by nature receive affection) would be related significantly and positively to their reports of received affection from their grandparents (i.e., their scores on the GRAS). Additionally, a research question was asked to explore if grandchildren's received affection from their grandparents is dependent on their grandparent's biological sex or lineage (i.e., maternal vs paternal). Thus, young adult grandchildren (N = 422) completed the GRAS and the Trait Affection Received Scale. The results of zero-order Pearson correlational analyses provided support for the hypothesis, whereas the results of MANOVAs tests only partially support extant grandparent-grandchild theory and research. These findings broaden the scope of Affection Exchange Theory and also bolster the GRAS's utility in future grandparent-grandchild affectionate communication research.

  3. A Simple Experimental Setup for Teaching Additive Colors with Arduino (United States)

    Carvalho, Paulo Simeão; Hahn, Marcelo


    The result of additive colors is always fascinating to young students. When we teach this topic to 14- to 16-year-old students, they do not usually notice we use maximum light quantities of red (R), green (G), and blue (B) to obtain yellow, magenta, and cyan colors in order to build the well-known additive color diagram of Fig. 1. But how about using different light intensities for R, G, and B? What colors do we get? This problem of color mixing has been intensively discussed for decades by several authors, as pointed out by Ruiz's "Color Addition and Subtraction Apps" work and the references included therein. An early LED demonstrator for additive color mixing dates back to 1985, and apps to illustrate color mixing are available online. In this work, we describe an experimental setup making use of a microcontroller device: the Arduino Uno. This setup is designed as a game in order to improve students' understanding of color mixing.

  4. Influence of having breakfast on cognitive performance and mood in 13- to 20-year-old high school students: results of a crossover trial. (United States)

    Widenhorn-Müller, Katharina; Hille, Katrin; Klenk, Jochen; Weiland, Ulrike


    The goal was to determine whether breakfast had effects on the cognitive performance and mood of high school students. A crossover trial was performed in boarding schools, involving 104 students between 13 and 20 years of age. The participants were randomly assigned to 2 equal-size groups on the morning of the first testing day. One half of the total sample received a standardized breakfast, whereas the other half received no breakfast. Seven days later, the treatment order was reversed. Measurements of cognitive function included standardized tests of attention and concentration, as well as tests of verbal and spatial memory. In addition, mood was rated with a self-administered questionnaire covering the dimensions of positive and negative affect, information uptake, arousal, and alertness. Statistical analysis consisted of repeated-measures analysis of variance. Breakfast had no effect on sustained attention among high school students. Visuospatial memory was improved in male students. Self-reported alertness improved significantly in the entire study population. Male students reported feeling more positive after consuming breakfast, compared with the fasting condition. This crossover trial demonstrated positive short-term effects of breakfast on cognitive functioning and self-reported alertness in high school students.

  5. Educational experiment for university students using natural radioactivity. Development of an additional experiment to measure the increase in 214Pb and 214Bi produced from 222Rn

    International Nuclear Information System (INIS)

    Nakamura, Mariko; Esaka, Takao; Kamata, Masahiro


    Although several works have been published to date regarding radiochemistry, most of them have been designed for those who major in subjects related to chemistry or physics and use rather sophisticated methods and apparatus. Education about radiation and radioactivity is also very important for other students because a basic knowledge of radiation and radioactivity is indispensable for understanding environmental problems or energy problems in the future. However, it is not easy to conduct practical work using radioactivity in students' experiments at school or at university because the use of radioactivity is strictly regulated by the law, and equipment such as radiation counters is too expensive for school budgets. From such a viewpoint, we developed several kinds of safe and inexpensive experiments for education using natural radioactivity so that university (or senior high school) students can learn through their practical work without being regulated by the law. For this purpose, radioactive species belonging to the uranium decay series are suitable because these species can be easily obtained from mineral spring water or soil samples. In addition, some of the species such as 214 Pb and 214 Bi emit beta rays, which are easy to detect, and the half-lives of these which are easy to detect, and the half-lives of these elements can be measured in one or two-hour school activities. This kind of experiment was employed as an ''Educational experiment for radiochemistry'' at Tottori University for nearly fifty students every year. Although the experiment itself was essentially complete, the students did not have the chance to observe how radioactive equilibrium was established. Therefore, we have developed an additional work plan to enable students to observe how 214 Pb and 214 Bi are produced from 222 Rn, and have made this experiment more complete. The educational usefulness of this additional experiment was evaluated and will be presented in section 5. (author)

  6. Effectiveness of a co-taught handwriting program for first grade students. (United States)

    Case-Smith, Jane; Holland, Terri; White, Susan


    Our study examined the effects of Write Start, a classroom-embedded handwriting/writing program on handwriting and writing fluency for first grade students, co-taught by occupational therapists and teachers. Two first grade classrooms received the Write Start and two received standard handwriting instruction. This co-taught program included specific feedback during handwriting practice, small group activities, student self-evaluation, and peer supports. The students were evaluated on handwriting legibility, fluency, and written expression at baseline, immediately after the program, and 6 months later. When performance was compared between the two groups, the students in the Write Start program improved significantly more in legibility (d = .57) and fluency (d = .75) than students who received standard instruction. Gains in handwriting speed (d = .18), average legibility (d = .26), and written expression (d = .25) did not differ significantly between the two groups. A co-taught, inclusive handwriting/writing program can promote first grade students' achievement of lower case legibility and writing fluency.

  9. Student representational competence and self-assessment when solving physics problems

    Directory of Open Access Journals (Sweden)

    Noah D. Finkelstein


    Full Text Available Student success in solving physics problems is related to the representational format of the problem. We study student representational competence in two large-lecture algebra-based introductory university physics courses with approximately 600 participants total. We examined student performance on homework problems given in four different representational formats (mathematical, pictorial, graphical, verbal, with problem statements as close to isomorphic as possible. In addition to the homeworks, we examine students’ assessment of representations by providing follow-up quizzes in which they chose between various problem formats. As a control, some parts of the classes were assigned a random-format follow-up quiz. We find that there are statistically significant performance differences between different representations of nearly isomorphic statements of quiz and homework problems. We also find that allowing students to choose which representational format they use improves student performance under some circumstances and degrades it in others. Notably, one of the two courses studied shows much greater performance differences between the groups that received a choice of format and those that did not, and we consider possible causes. Overall, we observe that student representational competence is tied to both micro- and macrolevel features of the task and environment.

  11. Sodium reflux pool-boiler solar receiver on-sun test results

    Energy Technology Data Exchange (ETDEWEB)

    Andraka, C E; Moreno, J B; Diver, R B; Moss, T A [Oak Ridge National Lab., TN (United States)


    The efficient operation of a Stirling engine requires the application of a high heat flux to the relatively small area occupied by the heater head tubes. Previous attempts to couple solar energy to Stirling engines generally involved directly illuminating the heater head tubes with concentrated sunlight. In this study, operation of a 75-kW{sub t} sodium reflux pool-boiler solar receiver has been demonstrated and its performance characterized on Sandia's nominal 75-kW{sub t} parabolic-dish concentrator, using a cold-water gas-gap calorimeter to simulate Stirling engine operation. The pool boiler (and more generally liquid-metal reflux receivers) supplies heat to the engine in the form of latent heat released from condensation of the metal vapor on the heater head tubes. The advantages of the pool boiler include uniform tube temperature, leading to longer life and higher temperature available to the engine, and decoupling of the design of the solar absorber from the engine heater head. The two-phase system allows high input thermal flux, reducing the receiver size and losses, therefore improving system efficiency. The receiver thermal efficiency was about 90% when operated at full power and 800{degree}C. Stable sodium boiling was promoted by the addition of 35 equally spaced artificial cavities in the wetted absorber surface. High incipient boiling superheats following cloud transients were suppressed passively by the addition of small amounts of xenon gas to the receiver volume. Stable boiling without excessive incipient boiling superheats was observed under all operating conditions. The receiver developed a leak during performance evaluation, terminating the testing after accumulating about 50 hours on sun. The receiver design is reported here along with test results including transient operations, steady-state performance evaluation, operation at various temperatures, infrared thermography, x-ray studies of the boiling behavior, and a postmortem analysis.

  14. A Decentralized Receiver in Gaussian Interference

    Directory of Open Access Journals (Sweden)

    Christian D. Chapman


    Full Text Available Bounds are developed on the maximum communications rate between a transmitter and a fusion node aided by a cluster of distributed receivers with limited resources for cooperation, all in the presence of an additive Gaussian interferer. The receivers cannot communicate with one another and can only convey processed versions of their observations to the fusion center through a Local Array Network (LAN with limited total throughput. The effectiveness of each bound’s approach for mitigating a strong interferer is assessed over a wide range of channels. It is seen that, if resources are shared effectively, even a simple quantize-and-forward strategy can mitigate an interferer 20 dB stronger than the signal in a diverse range of spatially Ricean channels. Monte-Carlo experiments for the bounds reveal that, while achievable rates are stable when varying the receiver’s observed scattered-path to line-of-sight signal power, the receivers must adapt how they share resources in response to this change. The bounds analyzed are proven to be achievable and are seen to be tight with capacity when LAN resources are either ample or limited.

  15. Performance evaluation of nursing students following competency-based education. (United States)

    Fan, Jun-Yu; Wang, Yu Hsin; Chao, Li Fen; Jane, Sui-Whi; Hsu, Li-Ling


    Competency-based education is known to improve the match between educational performance and employment opportunities. This study examined the effects of competency-based education on the learning outcomes of undergraduate nursing students. The study used a quasi-experimental design. A convenience sample of 312 second-year undergraduate nursing students from northern and southern Taiwan participated in the study. The experimental group (n=163) received competency-based education and the control group received traditional instruction (n=149) in a medical-surgical nursing course. Outcome measures included students' scores on the Objective Structured Clinical Examination, Self-Evaluated Core Competencies Scale, Metacognitive Inventory for Nursing Students questionnaire, and academic performance. Students who received competency-based education had significantly higher academic performance in the medical-surgical nursing course and practicum than did the control group. Required core competencies and metacognitive abilities improved significantly in the competency-based education group as compared to the control group after adjusting for covariates. Competency-based education is worth implementing and may close the gap between education and the ever-changing work environment. Copyright © 2014 Elsevier Ltd. All rights reserved.

  17. Student Incivility in Radiography Education. (United States)

    Clark, Kevin R


    To examine student incivility in radiography classrooms by exploring the prevalence of uncivil behaviors along with the classroom management strategies educators use to manage and prevent classroom disruptions. A survey was designed to collect data on the severity and frequency of uncivil student behaviors, classroom management strategies used to address minor and major behavioral issues, and techniques to prevent student incivility. The participants were educators in radiography programs accredited by the Joint Review Committee on Education in Radiologic Technology. Findings indicated that severe uncivil student behaviors in radiography classrooms do not occur as often as behaviors classified as less severe. Radiography educators in this study used a variety of strategies and techniques to manage and prevent student incivility; however, radiography educators who received formal training in classroom management reported fewer incidents of student incivility than those who had not received formal training. The participants in this study took a proactive approach to addressing severe behavioral issues in the classroom. Many radiography educators transition from the clinical environment to the classroom setting with little to no formal training in classroom management. Radiography educators are encouraged to attend formal training sessions to learn how to manage the higher education classroom effectively. Student incivility is present in radiography classrooms. This study provides a foundation for future research on incivility. ©2017 American Society of Radiologic Technologists.

  20. Dental hygiene students' part-time jobs in dental practices in the Netherlands. (United States)

    Poorterman, J H G; Dikkes, B T; Brand, H S


    Many students have paid employment while studying. In the Netherlands, the Individual Health Care Professions Act (IHCP Act) allows dental hygiene students to work under certain conditions in a dental practice. The aim of the study was to determine how many dental hygiene students have part-time job employment in dental practice and which professional tasks they carry out. We also asked the dental hygiene students their opinion of the IHCP Act. All the enrolled dental hygiene students (n = 341) at a School of Health in the Netherlands received a questionnaire by email. The response was 52% (176 students). Of the responding students, 75% had paid employment in addition to their study. A proportion of the students (35%) worked in a dental practice. The median number of hours worked per week was eight. Study year, age and prior education were positively related to working part-time in dental practice. Activities frequently performed were giving oral hygiene instruction, fluoride applications, scaling and root planning, providing chair side assistance and giving local anaesthesia. Although the self-reported knowledge about the IHCP Act was high, almost half of the students expressed the need for more detailed legal information. Many dental hygiene students work in a dental practice, taking over a number of tasks usually performed by the dentist. More information in the dental hygiene curriculum about the requirements of the IHCP Act seems desirable.

    Rogers, David A; Boehler, Margaret L; Schwind, Cathy J; Meier, Andreas H; Wall, Jarrod C H; Brenner, Michael J


    There are potential advantages to engaging medical students in the feedback process, but efforts to do so have yielded mixed results. The purpose of this study was to evaluate a student-focused feedback instructional session in an experimental setting. Medical students were assigned randomly to either the intervention or control groups and then assigned randomly to receive either feedback or compliments. Tests of knowledge, skills, and attitudes were given before and after the intervention. There was a significant gain of knowledge and skill in the group that received instruction. Satisfaction was higher after compliments in the control group but higher after feedback in the instructional group. There was no change in the subject's willingness to seek feedback. A student-focused component should be carefully included as part of an overall effort to improve feedback in surgical education. The role of medical student attitudes about feedback requires further investigation. Copyright © 2012 Elsevier Inc. All rights reserved.

    Sheriff, Ibrahim Hasanyn Naim; Ahmed, Faheem; Jivraj, Naheed; Wan, Jonathan C M; Sampford, Jade; Ahmed, Na'eem


    Purpose Effective clinical leadership is crucial to avoid failings in the delivery of safe health care, particularly during a period of increasing scrutiny and cost-constraints for the National Health Service (NHS). However, there is a paucity of leadership training for health-care students, the future leaders of the NHS, which is due in part to overfilled curricula. The purpose of this study was to assess the impact of student-led leadership training for the benefit of fellow students. Design/methodology/approach To address this training gap, a group of multiprofessional students organised a series of large-group seminars and small-group workshops given by notable health-care leaders at a London university over the course of two consecutive years. Findings The majority of students had not previously received any formal exposure to leadership training. Feedback post-events were almost universally positive, though students expressed a preference for experiential teaching of leadership. Working with university faculty, an inaugural essay prize was founded and student members were given the opportunity to complete internships in real-life quality improvement projects. Originality/value Student-led teaching interventions in leadership can help to fill an unmet teaching need and help to better equip the next generation of health-care workers for future roles as leaders within the NHS.

  4. How do Student Clients of a University-based Food Bank Cope with Food Insecurity? (United States)

    Farahbakhsh, Jasmine; Ball, Geoff D C; Farmer, Anna P; Maximova, Katerina; Hanbazaza, Mahitab; Willows, Noreen D


    To describe the food security status, food insecurity coping strategies, characteristics, and experiences of student clients of the Campus Food Bank (CFB) at the University of Alberta in Edmonton, Alberta, Canada. A convenience sample of 58 students completed a survey from April 2013 to April 2014. Food security status was determined using the "Adult Food Security Survey Module". Ninety percent of CFB student clients who participated in this study were food insecure, which included both moderately and severely food insecure groups. The most prevalent coping strategies for food insecurity included applying for a loan or bursary (86.2%), seeking employment or working more hours (84.5%), and purchasing food using a credit card (77.6%). Participants were a diverse mix of students, including graduate students (50.0%), international students (46.6%), and caregivers of children (24.1%). The most common primary sources of income were government student loans (29.3%) and research assistantships (20.7%). Most participants (82.8%) liked the food they received from the food bank. Food insecurity is highly prevalent among student clients of this university-based food bank. Students used a variety of coping strategies to increase their disposable income, highlighting the need for additional strategies to alleviate food insecurity among vulnerable students.

  5. Retention of Knowledge following training of students in Basic Trauma Life Support. (United States)

    Lim, K G; Lum, S K; Burud, I A S


    In the course of their undergraduate training at the International Medical University, students receive a Basic Trauma Life Support course. We wanted to test the long-term retention of knowledge (after 16 months) of third year medical students who had received training in Basic Trauma Life Support Method: To assess the retention of knowledge one cohort of students who received the training course were tested again 16 months later using the same 30 question One Best Answer quiz. Seventy-three students who underwent the course sat for the Retention test. The number of students who passed the Retention test was not significantly different from the test taken immediately after the course. The mean scores, 62.5% and 59.5% respectively, were however significantly different. Our study involves a relatively long interval between the course and retention of knowledge test shows encouraging results.

    and Costas's PLL (Phase Lock Loop models of loop tracking of signal synchronization are presented. The analysis is performed by processing the signals from the same satellite and under the same conditions of the initial signal synchronization. The multiple signal processing showed the advantages and disadvantages of the particular methods and the most acceptable solution proved to be the implementation of the DLL tracking loop phase synchronization and the code tracking loop PLL carrier frequency synchronization. The influence of the parameters of the loop itself is shown as well. After the extraction of navigation bits, all bit extracts do not come with an equal phase. This may lead to a wrong decision in rejecting the Decider and bits. Therefore, the paper proposes an additional synchronization of the extracted bits selected by the navigation messages NDA (Non-Data-Aided algorithm in order to perform their correct detection and to position the receiver much faster. Comparison of methods of signal synchronization Based on the analysis of the methods, the simulation results are compared. The results showed that the TDL loop is not resistant to dynamic disturbances of signals, since the synchronization tracking breaks up. In addition, this loop shows susceptibility to the noise from free space. These are sufficient reasons to propose the implementation of the DLL signal tracking loop as an acceptable solution. In addition to the proposal of the tracking loop, tracking loop coefficient values are determined. Conclusion The performed analysis showed that the TDL loop is not resistant to noise and dynamic disorders of the input signal. Therefore, an appropriate solution for the implementation is the DLL loop with six correlates. The DLL tracking loop coefficients are determined as a compromise solution and they are B = 2Hz and γ = 0.7. Also, the coefficients of the PLL tracking loop of frequency synchronization are B = 20Hz and γ = 0.7. The application of the NDA

  8. [Evaluation of the impact of a training program on vitamin K antagonists (VKA) implemented by pharmacy students aiming at improving the knowledge of patients receiving vitamin K antagonists during their hospital clinical training course]. (United States)

    Conort, O; Siguret, V; Bourdon, O; Nazaraly, S; Brignone, M; Pons-Kerjean, N; Houze, S; Laribe Cage, S; Berthet, F; Golmard, J-L; Brion, F; Tilleul, P


    We developed a training program for pharmacy students aiming at supporting patients receiving vitamin K antagonists (VKAs). The objective was to estimate how the program impacts VKA-treated patient knowledge acquisition and/or improvement on their anticoagulant treatment. Using dedicated tools, pharmacy students received education on VKA treatment. Once appointed to clinical wards of Assistance publique-Hôpitaux de Paris, they were in charge of evaluating patient's knowledge on VKA treatment before and after training. Evaluation was conducted using a face-to-face standardized interview (14-item questionnaire). A global score was calculated for each patient. An univariate and multivariate analysis was performed to identify potential variables influencing score result. One hundred and seventy VKA-treated patients were recruited in seven hospitals for evaluation of their knowledge on VKA treatment and on clinical at risk situations. Before intervention, patients obtained an average score of 12.3±3.2 (maximum: 18). Factors significantly associated with the score were possession of a VKA information booklet, VKA treatment duration, treatment initiation and age. Fifty-two patients with a low score were further trained by the pharmacy student. After intervention, their initial score was improved significantly, from 9.9±3.3 to 13.5±2.3 (P<0.0001). Increasing patient knowledge is a way to decrease the rate of adverse effects. This study demonstrates that patients with primary poor knowledge improved it significantly thanks to pharmacy students' intervention. This may contribute to lower the VKA-associated risk of adverse events and consequently to the improvement of patients quality of life and healthcare expenditures.

    questions to determine reading comprehension and retention. Students also completed a demographic questionnaire to measure their typical instant messaging behaviour, including the amount of time they spend each week instant messaging, how often IM software is on when their computer is on, and how often IM software is on when they are studying. Both of these activities took place on the same computers used for the reading experiment.Students were additionally asked to comment on the clarity of instructions, the representativeness of the task to their typical IM experiences, and the interest and similarity to normal coursework of the reading itself. These questions were asked on paper rather than on the computer.Software recorded the lengths of time each student spent in reading the passage, reading and responding to IMs, and answering the online questions. For those students who received IMs during reading, the time spent from receipt of each IM to each response was subtracted from the total reading time.Main Results – There were no differences in test performance between the three groups. Statistically significant differences were found in the amount of time that students took to complete the reading: students who instant messaged during reading took significantly longer to read the online text than those students who instant messaged before reading and those who did not IM, even when time spent receiving and responding to IMs was subtracted from the totals. Students who instant messaged before reading took the least amount of time in the exercise. Further statistical analysis revealed no significant differences in the time spent instant messaging between the two IM groups.Responses to the demographic questions indicate that students spend a mean 7.5 hours instant messaging per week, that 67% of students have IM software on “sometimes,” “often,” or “very often” while the computer is on and 62% of the time while studying. Analysis indicated that none of the IM

  10. Peer to peer mentoring: Outcomes of third-year midwifery students mentoring first-year students. (United States)

    Hogan, Rosemarie; Fox, Deborah; Barratt-See, Georgina


    Undergraduate midwifery students commonly experience anxiety in relation to their first clinical placement. A peer mentoring program for midwifery students was implemented in an urban Australian university. The participants were first-year mentee and third-year mentor students studying a three-year Bachelor degree in midwifery. The program offered peer support to first-year midwifery students who had little or no previous exposure to hospital clinical settings. Mentors received the opportunity to develop mentoring and leadership skills. The aim was to explore the benefits, if any, of a peer mentoring program for midwifery students. The peer mentoring program was implemented in 2012. Sixty-three peer mentors and 170 mentees participated over three academic years. Surveys were distributed at the end of each academic year. Quantitative survey data were analysed descriptively and qualitative survey data were analysed thematically using NVivo 10 software. Over 80% of mentors and mentees felt that the program helped mentees adjust to their midwifery clinical placement. At least 75% of mentors benefited, in developing their communication, mentoring and leadership skills. Three themes emerged from the qualitative data, including 'Receiving start-up advice'; 'Knowing she was there' and 'Wanting more face to face time'. There is a paucity of literature on midwifery student peer mentoring. The findings of this program demonstrate the value of peer support for mentees and adds knowledge about the mentor experience for undergraduate midwifery students. The peer mentor program was of benefit to the majority of midwifery students. Copyright © 2017 Australian College of Midwives. Published by Elsevier Ltd. All rights reserved.

  11. Problem-based learning at the receiving end: a 'mixed methods' study of junior medical students' perspectives. (United States)

    Maudsley, Gillian; Williams, Evelyn M I; Taylor, David C M


    Qualitative insights about students' personal experience of inconsistencies in implementation of problem-based learning (PBL) might help refocus expert discourse about good practice. This study explored how junior medical students conceptualize: PBL; good tutoring; and less effective sessions. Participants comprised junior medical students in Liverpool 5-year problem-based, community-orientated curriculum. Data collection and analysis were mostly cross-sectional, using inductive analysis of qualitative data from four brief questionnaires and a 'mixed' qualitative/quantitative approach to data handling. The 1999 cohort (end-Year 1) explored PBL, generated 'good tutor' themes, and identified PBL (dis)advantages (end-Year 1 then mid-Year 3). The 2001 cohort (start-Year 1) described critical incidents, and subsequently (end-Year 1) factors in less effective sessions. These factors were coded using coding-frames generated from the answers about critical incidents and 'good tutoring'. Overall, 61.2% (137), 77.9% (159), 71.0% (201), and 71.0% (198) responded to the four surveys, respectively. Responders perceived PBL as essentially process-orientated, focused on small-groupwork/dynamics and testing understanding through discussion. They described 'good tutors' as knowing when and how to intervene without dominating (51.1%). In longitudinal data (end-Year 1 to mid-Year 3), the main perceived disadvantage remained lack of 'syllabus' (and related uncertainty). For less effective sessions (end-Year 1), tutor transgressions reflected unfulfilled expectations of good tutors, mostly intervening poorly (42.6% of responders). Student transgressions reflected the critical incident themes, mostly students' own lack of work/preparation (54.8%) and other students participating poorly (33.7%) or dominating/being self-centred (31.6%). Compelling individual accounts of uncomfortable PBL experiences should inform improvements in implementation.

  12. Wide-band coherent receiver development for enhanced surveillance

    International Nuclear Information System (INIS)

    Simpson, M.L.; Richards, R.K.; Hutchinson, D.P.


    Oak Ridge National Laboratory (ORNL) has been developing advanced coherent IR heterodyne receivers for plasma diagnostics in fusion reactors for over 20 years. Recent progress in wide band IR detectors and high speed electronics has significantly enhanced the measurement capabilities of coherent receivers. In addition, developments in new HgCdTe and quantum well IR photodetector (QWIP) focal plane arrays are providing the possibility of both active and passive coherent imaging. In this paper the authors discuss the implications of these new enabling technologies to the IR remote sensing community for enhanced surveillance. Coherent receivers, as opposed to direct or thermal detection, provide multiple dimensions of information about a scene or target in a single detector system. Combinations of range, velocity, temperature, and chemical species information are all available from a coherent heterodyne receiver. They present laboratory data showing measured noise equivalent power (NEP) of new QWIP detectors with heterodyne bandwidths greater than 7 GHz. For absorption measurements, a wide band coherent receiver provides the capability of looking between CO 2 lines at off-resonance peaks and thus the measurement of lines normally inaccessible with conventional heterodyne or direct detection systems. Also described are differential absorption lidar (DIAL) and Doppler laboratory measurements using an 8 x 8 HgCdTe focal plane array demonstrating the snapshot capability of coherent receiver detector arrays for enhanced chemical plume and moving hardbody capture. Finally they discuss a variety of coherent receiver configurations that can suppress (or enhance) sensitivity of present active remote sensing systems to speckle, glint, and other measurement anomalies

Drawing on the 2014 survey conducted by the Agency for the Quality of the Catalan University System, among students that graduated in 2010, we test three hypotheses. The first states that graduate valuation of the training received at university in terms of its utility for the workplace is higher among those who a...

  14. Three Social Classroom Applications to Improve Student Attitudes

    Directory of Open Access Journals (Sweden)

    Alf Inge Wang


    Full Text Available The paper presents results of a quasiexperiment where the three social classroom applications Post-It, WordCloud, and Categorizer were used in software architecture lectures. Post-It and WordCloud are applications that allow students to brainstorm or give comments related to a given topic. Categorizer is a puzzle game where the students are asked to place a number of terms in one of two correct categories. The three applications are multimodal HTML5 applications that enable students to interact in a classroom using their own digital devices, and the teacher’s laptop is used to display progress and results on the large screen. The focus of this study was to evaluate how the difference of these applications and how their integration into the lecture affected the students’ motivation, engagement, thinking, activity level, social interaction, creativity, enjoyment, attention, and learning. In addition, the study evaluated the usability and the technical quality of the applications. The results of the experiment show that the way such applications are integrated into a lecture highly affects the students’ attitude. The experiment also showed that the game-based application was on average better received among the students and that the students’ attitude was highly sensitive to the difficulty level of the game.

  17. Reading comprehension of deaf students in regular education. (United States)

    Luccas, Marcia Regina Zemella; Chiari, Brasília Maria; Goulart, Bárbara Niegia Garcia de


    To evaluate and compare the reading comprehension of deaf students included in regular classrooms of public schools with and without specialized educational support. Observational analytic study with 35 students with sensorineural hearing loss, with and without educational support. All subjects were assessed with the Word Reading Competence Test (WRCT), the Picture-Print Matching Test by Choice (PPMT-C), and the Sentence Reading Comprehension Test (SRCT). In the tests regarding comprehension of words (WRCT and PPMT-C), the results showed no difference in the performance of deaf students who attend and do not attend educational support. Regarding reading comprehension of sentences, the application of the SRCT also did not show differences between the groups of deaf students. A significant correlation was found between age and grade, indicating that the older the students and the higher their educational level, the better their performance in reading sentences. The results indicate that deaf students, regardless of attending educational support, read words better than sentences. There is no difference in reading comprehension between deaf students who receive and do not receive specialized pedagogical monitoring.

  18. Attitudes of Nursing Facilities' Staff Toward Pharmacy Students' Interaction with its Residents. (United States)

    Adkins, Donna; Gavaza, Paul; Deel, Sharon


    All Appalachian College of Pharmacy second-year students undertake the longitudinal geriatric early pharmacy practice experiences (EPPE) 2 course, which involves interacting with geriatric residents in two nursing facilities over two semesters. The study investigated the nursing staff's perceptions about the rotation and the pharmacy students' interaction with nursing facility residents. Cross-sectional study. Academic setting. 63 nursing facility staff. A 10-item attitude survey administered to nursing staff. Nursing staff attitude toward pharmacy students' interaction with geriatric residents during the course. Sixty-three responses were received (84% response rate). Most respondents were female (95.2%), who occasionally interacted with pharmacy students (54.8%) and had worked at the facilities for an average of 6.8 years (standard deviation [SD] = 6.7) years. Staff reported that pharmacy students practiced interacting with geriatric residents and nursing facility staff, learned about different medications taken by residents as well as their life as a nursing facility resident. In addition, the student visits improved the mood of residents and staff's understanding of medicines, among others. Staff suggested that students spend more time with their residents in the facility as well as ask more questions of staff. The nursing facility staff generally had favorable attitudes about pharmacy students' visits in their nursing facility. Nursing facility staff noted that the geriatric rotation was a great learning experience for the pharmacy students.

  1. Travel health risk perceptions and prevention behaviors of US study abroad students. (United States)

    Hartjes, Laurie B; Baumann, Linda C; Henriques, Jeffrey B


    The number of American study abroad students increased more than 150% in the past decade, along with growth in destinations with increased health risks. This study investigated travel health risk perceptions and prevention behaviors to guide interventions that address the emerging health needs of US study abroad students. A cross-sectional design was used to collect data from 318 American study abroad students using a Web-based survey. The primary source of travel health information was youth-oriented travel guidebooks (85%). The grand mean risk perception score for 18 travel health threats was 1.7 on a 1 to 4 scale, with top-rated threats being contaminated food/water, psychological distress, personal assault, and excessive sun exposure. Predeparture advice was received from primary care providers (52%) and travel health specialists (18%). Additional prevention measures were vaccines (42%) and medication (24%). Of 114 students listing their travel vaccinations, 11% described receiving a malaria vaccine and 4% a hepatitis C vaccine, although no such vaccines exist. Most respondents were confident/very confident in their ability to engage in prevention behaviors (94%). Health problems were primarily infectious disease (70%), psychological distress (10%), and injuries (8%). When asked if prior travel destinations involved areas where malaria transmission occurs, 20% responded, "Don't know." Identified gaps in travel health knowledge and prevention behaviors may produce hazardous consequences when combined with low-perceived risk, reliance on travel guidebooks for health information, and high ratings for prevention self-efficacy. Future research is needed to test the effectiveness of educational interventions designed for student travelers who would benefit from guided practice with destination-specific risk appraisal and prevention planning. Web-based educational resources are a good fit for this population because they are easily updated, available in all phases of

  2. Midwifery student reactions to workplace violence. (United States)

    Shapiro, Jesse; Boyle, Malcolm J; McKenna, Lisa


    Workplace violence, incidents against people in their workplaces, is a growing problem in Australia causing untold personal suffering as well as costing Australian businesses in productivity. Midwives have been highlighted as a group particularly at risk, yet in Australia there is little research into workplace violence against midwives and even less into midwifery students. This study aimed to explore Australian midwifery students' responses to workplace violence as well as to gauge the impact of workplace violence on them. Cross-sectional survey design was employed. Second and third year students were invited to participate at the end of a scheduled lecture. Fifty-two female midwifery students who had completed their work placement completed a survey indicating their immediate responses to workplace violence as well as the Impact of Event Scale. Data were analysed using descriptive statistics. Most students notified a co-worker immediately after a workplace violence incident, yet few completed an incident form or received official debriefing. There is a need for the reporting of workplace violence against midwifery students to be made easier to access thereby ensuring they can receive the assistance they require. Midwifery students need to understand the processes and supports in place for managing instances of workplace violence. Clinical placements can impact on midwifery students' future careers. Universities need to prepare students for the possibility of workplace violence and arm them with appropriate strategies for safely dealing with it. Crown Copyright © 2017. Published by Elsevier Ltd.

  3. Students' reflections in a portfolio pilot: highlighting professional issues. (United States)

    Haffling, Ann-Christin; Beckman, Anders; Pahlmblad, Annika; Edgren, Gudrun


    Portfolios are highlighted as potential assessment tools for professional competence. Although students' self-reflections are considered to be central in the portfolio, the content of reflections in practice-based portfolios is seldom analysed. To investigate whether students' reflections include sufficient dimensions of professional competence, notwithstanding a standardized portfolio format, and to evaluate students' satisfaction with the portfolio. Thirty-five voluntary final-year medical students piloted a standardized portfolio in a general practice (GP) attachment at Lund University, Sweden. Students' portfolio reflections were based upon documentary evidence from practice, and aimed to demonstrate students' learning. The reflections were qualitatively analysed, using a framework approach. Students' evaluations of the portfolio were subjected to quantitative and qualitative analysis. Among professional issues, an integration of cognitive, affective and practical dimensions in clinical practice was provided by students' reflections. The findings suggested an emphasis on affective issues, particularly on self-awareness of feelings, attitudes and concerns. In addition, ethical problems, clinical reasoning strategies and future communication skills training were subjects of several reflective commentaries. Students' reflections on their consultation skills demonstrated their endeavour to achieve structure in the medical interview by negotiation of an agenda for the consultation, keeping the interview on track, and using internal summarizing. The importance of active listening and exploration of patient's perspective was also emphasized. In students' case summaries, illustrating characteristic attributes of GP, the dominating theme was 'patient-centred care', including the patient-doctor relationship, holistic modelling and longitudinal continuity. Students were satisfied with the portfolio, but improved instructions were needed. A standardized portfolio in a

  4. An e-learning reproductive health module to support improved student learning and interaction: a prospective interventional study at a medical school in Egypt (United States)


    Background The Public Health (PH) course at the medical college of Cairo University is based on traditional lectures. Large enrollment limits students' discussions and interactions with instructors. Aim Evaluate students' learning outcomes as measured by improved knowledge acquisition and opinions of redesigning the Reproductive Health (RH) section of the PH course into e-learning and assessing e-course utilization. Methods This prospective interventional study started with development of an e-learning course covering the RH section, with visual and interactive emphasis, to satisfy students' diverse learning styles. Two student groups participated in this study. The first group received traditional lecturing, while the second volunteered to enroll in the e-learning course, taking online course quizzes. Both groups answered knowledge and course evaluation questionnaires and were invited to group discussions. Additionally, the first group answered another questionnaire about reasons for non-participation. Results Students participating in the e-learning course showed significantly better results, than those receiving traditional tutoring. Students who originally shunned the e-course expressed eagerness to access the course before the end of the academic year. Overall, students using the redesigned e-course reported better learning experiences. Conclusions An online course with interactivities and interaction, can overcome many educational drawbacks of large enrolment classes, enhance student's learning and complement pit-falls of large enrollment traditional tutoring.

Both groups answered knowledge and course evaluation questionnaires and were invited to group discussions. Additionally, the first group answered another questionnaire about reasons for non-participation. Results Students participating in the e-learning course showed significantly better results, than those receiving traditional tutoring. Students who originally shunned the e-course expressed eagerness to access the course before the end of the academic year. Overall, students using the redesigned e-course reported better learning experiences. Conclusions An online course with interactivities and interaction, can overcome many educational drawbacks of large enrolment classes, enhance student's learning and complement pit-falls of large enrollment traditional tutoring.

  6. Providing Students with Foundational Field Instruction within a 50 Minute Class Period: A Practical Example (United States)

    Percy, M.


    There is a growing recognition among secondary educators and administrators that students need to have a science education that provides connections between familiar classes like biology, chemistry, and physics. Because of this waxing interest in an integrative approach to the sciences, there is a broader push for school districts to offer classes geared towards the earth sciences, a field that incorporates knowledge and skills gleaned from the three core science subjects. Within the contexts of a regular secondary school day on a traditional schedule (45- to 50-minute long classes), it is challenging to engage students in rigorous field-based learning, critical for students to develop a deeper understanding of geosciences content, without requiring extra time outside of the regular schedule. We suggest instruction using common, manmade features like drainage retention ponds to model good field practices and provide students with the opportunity to calculate basic hydrologic budgets, take pH readings, and, if in an area with seasonal rainfall, make observations regarding soils by way of trenching, and near-surface processes, including mass wasting and the effects of vegetation on geomorphology. Gains in student understanding are discussed by analyzing the difference in test scores between exams provided to the students after they had received only in-class instruction, and after they had received field instruction in addition to the in-class lectures. In an advanced setting, students made measurements regarding ion contents and pollution that allowed the classes to practice lab skills while developing a data set that was analyzed after field work was completed. It is posited that similar fieldwork could be an effective approach at an introductory level in post-secondary institutions.

    This research aims to study the incorporation of the mass of electric arc furnace dust (EAFD), by addition in hot metal (1.78% Si) at a temperature of 1,400 degrees Celsius. The EAFD is from a steel plant producing long steel. The addition of the EAFD was as received, in the form of briquettes without agitation of the hot metal and in the form of briquettes with agitation of the hot metal. Previously, the EAFD was characterized using the following techniques: chemical analysis, size analysis, X-ray diffraction, scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS) microanalysis. The achievement of fusion experiments in laboratory scale, took place in a vertical tubular furnace with temperature control. The fusion experiments to assess the incorporation of EAFD mass used graphite crucibles. After cooling, the hot metal and the slag, remaining in the crucible, were weighed to do a mass balance. A flow of inert gas (argon) was maintained inside the furnace during the experiments. Results show that the experiment with addition of EAFD as received presents the best result of incorporating the mass of the final hot metal (1.73%) combined with the lowest percentage of volatilized mass of EAFD (46.52%). The experiment addition of EAFD in the form of briquette with agitation of hot metal presents the lowest percentage of slag mass (4.58%). The zinc content of volatilized EAFD (64.30%) is higher than the zinc content of the imported ore concentrate (52%) and zinc content of the national ore concentrate (12% to 39%). The presence of lead and cadmium in the slag characterizing it as a hazardous solid waste. (author)

    Masoud Kowsari


    Full Text Available Recently, cell phone, as an unlimited media, in comparison with others, has deeply changed the modes of interpersonal connections. Accessibility, and inexpensiveness, in addition to the transcendence of normal face to face relation restrictions, could be taken for granted as most fascinating features of SMS. Therefore, content analysis of the SMS could help to clarify the communicative subjectivities in interpersonal communications. This study tends to analyze the content of 2651 short messages exchanged among 80 students both genders, in various universities in Tehran. This paper attempts to answer the following questions: Who are the main senders of the messages? In what time are the SMS s frequently s sent or received? What are the most frequent contents? Is there any relationship between the gender of recipients/senders and the content of the messages? Whether the contents are related to the marital statue of the receiver and sender or not?

  13. Utilizing LMS tools to help with student assessment in an online course

    Directory of Open Access Journals (Sweden)

    Dudley B. Turner


    Full Text Available In online learning, feedback to students is important in their progress. Assessments are often final or summative assessments that do not allow the student to adjust or improve their learning progress. Assessment, however, takes valuable time. This paper describes how using the tools available in a LMS can assist faculty in assessing student work and provide helpful feedback to students in an online course. The tools available for faculty to use can be set up to save time for the faculty during assessments. The assignments in this study were developed based on previous research indicating assessment can be an aid to student learning, and students who know how well they are doing can make needed adjustments. Students used the feedback from these LMS tools to decide whether or not to try again or move on. Students had the opportunity for multiple attempts at assignments and received feedback on each to help measure their learning. The rubric tool was used to not only grade student papers but also to provide appropriate feedback for student performance on the levels of achievement. Quizzes can be automatically graded. Any additional attempts are drawn from a bank of questions. Results from this pilot study show the benefits of multiple attempts at quizzes and assignments. Students who took advantage of multiple attempts did improve their scores. The paper also discusses further research that to help support this practice.

    Jeffrey, D.R.; Goddard, P.R.; Callaway, M.P.; Greenwood, R.


    AIM: To assess the ability of final year medical students to interpret conventional chest radiographs. MATERIALS AND METHODS: Ten conventional chest radiographs were selected from a teaching hospital radiology department library that were good radiological examples of common conditions. All were conditions that a medical student should be expected to recognize by the end of their training. One normal radiograph was included. The radiographs were shown to 52 final year medical students who were asked to describe their findings. RESULTS: The median score achieved was 12.5 out of 20 (range 6-18). There was no difference between the median scores of male and female students (12.5 and 12.3, respectively, p=0.82) but male students were more likely to be certain of their answers than female students (median certainty scores 23.0 and 14.0, respectively). The overall degree of certainty was low. On no radiograph were more than 25% of students definite about their answer. Students had received little formal radiology teaching (2-42 h, median 21) and few expressed an interest in radiology as a career. Only two (3.8%) students thought they were good at interpreting chest radiographs, 17 (32.7%) thought they were bad or awful. CONCLUSION: Medical students reaching the end of their training do not perform well at interpreting simple chest radiographs. They lack confidence and have received little formal radiological tuition. Perhaps as a result, few are interested in radiology as a career, which is a matter for concern in view of the current shortage of radiologists in the UK

    Monitored retrievable storage (MRS) will be required to handle a large volume of spent fuel or high-level waste (HLW) in case of delays in repository deployment. The quantities of materials to be received and repackaged for storage far exceed the requirements of existing waste mangement facilities. A computer simulation model of the MRS receiving and handling (R and H) fcility has been constructed and used to evaluate design alternatives. Studies have identified processes or activities which may constrain throughput performance. In addition, the model has helped to assess design tradeoffs such as those to be made among improved process times, redundant service lines, and improved component availability. 1 reference, 5 figures

  18. Stakeholders' Voices: Defining Needs of Students with Emotional and Behavioral Disorders Transitioning between School Settings. (United States)

    Buchanan, Rohanna; Nese, Rhonda N T; Clark, Miriam


    Students with emotional and behavioral disorders (EBD) too often do not receive adequate services or care in their school settings, particularly during transitions in educational placements. In addition, school support teams often struggle with creating transition plans that honor the needs of students with input from key stakeholders responsible for supporting student success. This article presents findings from the information-gathering phase of an iterative project that aims to develop a support program for students with EBD transitioning from day-treatment schools to district schools. We conducted 5 semistructured, qualitative focus groups with parents and teachers to explore needs during students' transitions between school settings. Five themes emerged from the focus groups: (a) consistent, behavior-specific feedback and positive reinforcement are vital to sustaining learned prosocial skills; (b) students benefit from regular opportunities to learn and practice social skills; (c) transition programming should emphasize communication between school and home; (d) routines at home and school should be coordinated; and (e) parents need support at school meetings. We will use findings from this study to develop a multifaceted intervention that aims to support students, their caregivers, and their teachers during transitions between the aforementioned types of schools.

    Rizal, Rachel E; Mediratta, Rishi P; Xie, James; Kambhampati, Swetha; Hills-Evans, Kelsey; Montacute, Tamara; Zhang, Michael; Zaw, Catherine; He, Jimmy; Sanchez, Magali; Pischel, Lauren


    Many national organizations call for medical students to receive more public health education in medical school. Nonetheless, limited evidence exists about successful servicelearning programs that administer preventive health services in nonclinical settings. The Flu Crew program, started in 2001 at the Stanford University School of Medicine, provides preclinical medical students with opportunities to administer influenza immunizations in the local community. Medical students consider Flu Crew to be an important part of their medical education that cannot be learned in the classroom. Through delivering vaccines to where people live, eat, work, and pray, Flu Crew teaches medical students about patient care, preventive medicine, and population health needs. Additionally, Flu Crew allows students to work with several partners in the community in order to understand how various stakeholders improve the delivery of population health services. Flu Crew teaches students how to address common vaccination myths and provides insights into implementing public health interventions. This article describes the Stanford Flu Crew curriculum, outlines the planning needed to organize immunization events, shares findings from medical students' attitudes about population health, highlights the program's outcomes, and summarizes the lessons learned. This article suggests that Flu Crew is an example of one viable service-learning modality that supports influenza vaccinations in nonclinical settings while simultaneously benefiting future clinicians.

  20. Near-peer role modeling: Can fourth-year medical students, recognized for their humanism, enhance reflection among second-year students in a physical diagnosis course?

    Mimi McEvoy


    Full Text Available Introduction: Humanism is cultivated through reflection and self-awareness. We aimed to employ fourth-year medical students, recognized for their humanism, to facilitate reflective sessions for second-year medical students with the intention of positively influencing reflective process toward humanistic development. Methods/Analysis: A total of 186 students were randomly assigned to one of three comparison arms: eight groups of eight students (64 students were facilitated by a fourth-year student who was a Gold Humanism Honor Society member (GHHS; eight groups (64 students by a volunteer non-GHHS student; and seven groups (58 students were non-facilitated. Before sessions, second-year students set learning goals concerning interactions with patients; fourth-year students received training materials on facilitation. Groups met twice during their 10 clinical site visits. At the last session, students completed a reflective assignment on their goal progress. Comparative mixed method analyses were conducted among the three comparison arms on reflection (reflective score on in-session assignment and session satisfaction (survey in addition to a thematic analysis of responses on the in-session assignment. Results: We found significant differences among all three comparison arms on students’ reflective scores (p=0.0003 and satisfaction (p=0.0001. T-tests comparing GHHS- and non-GHHS-facilitated groups showed significantly higher mean reflective scores for GHHS-facilitated groups (p=0.033; there were no differences on session satisfaction. Thematic analysis of students’ reflections showed attempts at self-examination, but lacked depth in addressing emotions. There was a common focus on achieving comfort and confidence in clinical skills performance. Discussion/Conclusions: Near peers, recognized for their humanism, demonstrated significant influence in deepening medical students’ reflections surrounding patient interactions or humanistic

  1. Final year student nurses' experiences of wound care: an evaluation. (United States)

    Ousey, Karen; Stephenson, John; Cook, Leanne; Kinsey, Laura; Batt, Sarah


    This article reports on research to explore if pre-registration nursing students felt prepared to manage patients' skin integrity effectively on registration. Final year nursing students completing adult, child and mental health fields were invited to complete questionnaires to investigate the amount of teaching sessions delivered in university in relation to managing skin integrity during their 3-year training programme, discover if pre-registration nursing students received supplementary management of skin integrity teaching in the clinical areas, explore which member of staff in the clinical areas supported the students' learning in the area of skin integrity. Data was collected on 217 final year students (196 females and 21 males) at two higher education institutions in the north of England. The majority of respondents (n = 146; 68%) reported receiving less than 10 hours formal teaching at university on the subject of skin integrity over their 3-year courses. Of those registered on degree courses, 134 students (71%) reported receiving less than 10 hours formal teaching over their 3-year courses, compared with only 12 students (46%) registered on diploma courses. Some 198 (99%) of respondents reported that their clinical teaching was undertaken by registered nurses all or some of the time. Other health professionals were reported to provide substantially less clinical teaching; with the next largest contribution reported to be provided by specialist nurses, who provided all clinical teaching to 36 respondents (19%) and some clinical teaching to 115 respondents (59%). Some 149 respondents (70%) reported that the teaching they received had developed their knowledge and skills to maintain skin integrity for all patients. Respondents claimed that teaching received had developed their knowledge and skills, reporting an average of 16.9 hours spent in directed study; whereas those who did not claim that teaching they had received had developed their knowledge and

  4. Resource-oriented coaching for reduction of examination-related stress in medical students: an exploratory randomized controlled trial. (United States)

    Kötter, Thomas; Niebuhr, Frank


    The years spent in acquiring medical education is considered a stressful period in the life of many students. Students whose mental health deteriorates during this long period of study are less likely to become empathic and productive physicians. In addition to other specific stressors, academic examinations seem to further induce medical school-related stress and anxiety. Combined group and individual resource-oriented coaching early in medical education might reduce examination-related stress and anxiety and, consequently, enhance academic performance. Good quality evidence, however, remains scarce. In this study, therefore, we explored the question of whether coaching affects examination-related stress and health in medical students. We conducted a randomized controlled trial. Students who registered for the first medical academic examination in August 2014 at the University of Lübeck were recruited and randomized into three groups. The intervention groups 1 and 2 received a 1-hour psychoeducative seminar. Group 1 additionally received two 1-hour sessions of individual coaching during examination preparation. Group 3 served as a control group. We compared changes in self-rated general health (measured by a single item), anxiety and depression (measured by the hospital anxiety and depression scale), as well as medical school stress (measured by the perceived medical school stress instrument). In order to further investigate the influence of group allocation on perceived medical school stress, we conducted a linear regression analysis. We saw a significant deterioration of general health and an increase in anxiety and depression scores in medical students while preparing for an examination. We found a small, but statistically significant, effect of group allocation on the development of perceived medical school stress. However, we could not differentiate between the effects of group coaching only and group coaching in combination with two sessions of individual

  5. A mandatory course in scientific writing for undergraduate medical students. (United States)

    Roland, C G; Cox, B G


    All students at Mayo Medical School take a course in scientific writing during their sophomore and junior years. Early in the sophomore year they receive a self-instructional text designed to help them avoid 15 common writing faults. Comparison of pretest and posttest results for two classes, with a total of 89 students, indicates significant improvement (p less than .001). Later in his sophomore year, each student writes a minithesis; and during his junior year he reports on work done in a clinical or laboratory research project, preparing it as a paper submissible to a scientific journal. Professional editors work as preceptors with the students, critiquing their manuscripts, which are revised until they receive satisfactory ratings.

  6. Anatomy drawing screencasts: enabling flexible learning for medical students. (United States)

    Pickering, James D


    The traditional lecture remains an essential method of disseminating information to medical students. However, due to the constant development of the modern medical curriculum many institutions are embracing novel means for delivering the core anatomy syllabus. Using mobile media devices is one such way, enabling students to access core material at a time and place that suits their specific learning style. This study has examined the effect of five anatomy drawing screencasts that replicate the popular anatomy drawing element of a lecture. These resources were uploaded to the University's Virtual Learning Environment for student access. Usage data and an end of module questionnaire were used to assess the impact of the screencasts on student education. The data revealed a high level of usage that varied in both the time of day and day of the week, with the number of downloads dramatically increasing towards the end of the module when the assessment was approaching. The student group found the additional resources extremely useful in consolidating information and revision, with many commenting on their preference to the screencasts compared to the more traditional approaches to learning. Scrutinizing the screencasts in relation to cognitive load theory and the cognitive theory of multimedia learning indicates a high correlation with an evidence-based approach to designing learning resources. Overall the screencasts have been a well-received enhancement that supports the student learning and has been shown to promote flexible learning. © 2014 American Association of Anatomists.

    The efficacy of administering a sodium-glucose cotransporter 2 inhibitor during insulin therapy has not been established. In this study, we examined its effects based on diurnal glycemic patterns using continuous glucose monitoring (CGM). The subjects were 15 patients who had received insulin therapy for 1 year or more. A CGM device was attached to all subjects for 1 week. The administration of canagliflozin at 100 mg was started 4 days after attachment. The mean glucose concentrations, standard deviation (SD), mean amplitude of glycemic excursions (MAGE), mean of daily difference of blood glucose (MODD), and area under the curve (AUC) (≥180, glucose concentrations decreased from 161.1 to 139.1 mg/dL (P AUC of ≥180, i.e., the total area of blood glucose levels at or above 180 on the blood glucose curve of CGM, decreased from 339.1 to 113.6 mg/dL (P AUC of blood glucose levels below 70 on the blood glucose curve of CGM, slightly decreased from 1.6 to 0.3 mg/dL (P = 0.08). The total number of basal insulin units decreased from 128 to 76, and that of bolus insulin decreased from 266 to 154; the dose of insulin could be markedly decreased. In addition, the mean 8-OHdG level decreased from 11.4 to 10.8 ng/mg Cre (P blood glucose changes in type 2 diabetes using insulin. In addition, the results suggest its antioxidant actions.

  10. Prevalence and Characteristics of School Services for High School Students with Attention-Deficit/Hyperactivity Disorder. (United States)

    Murray, Desiree W; Molina, Brooke S G; Glew, Kelly; Houck, Patricia; Greiner, Andrew; Fong, Dalea; Swanson, James; Arnold, L Eugene; Lerner, Marc; Hechtman, Lily; Abikoff, Howard B; Jensen, Peter S


    This study examines the prevalence and characteristics of services reported by school staff for 543 high school students participating in the 8 year follow-up of the multi-site Multimodal Treatment study of ADHD (MTA). Overall, 51.6% of students with a history of attention-deficit/hyperactivity disorder (ADHD) were receiving services through an Individualized Educational Plan (IEP) or a 504 plan, a rate higher than expected for this age group. Less than 5% of these had 504 plans; 35.5% attended special education classes. Very few services (except tutoring) were provided outside of an IEP or 504 plan. Almost all students with services received some type of academic intervention, whereas only half received any behavioral support or learning strategy. Less than one-fourth of interventions appear to be evidence-based. Students receiving services showed greater academic and behavioral needs than those not receiving services. Services varied based upon type of school, with the greatest number of interventions provided to students attending schools that only serve those with disabilities. Original MTA treatment randomization was unrelated to services, but cumulative stimulant medication and greater severity predicted more service receipt. Results highlight a need for accommodations with greater evidence of efficacy and for increased services for students who develop academic difficulties in high school.

  11. The effectiveness of mentoring speech and language pathology students when they face patients with cleft palate. (United States)

    Pamplona, María del Carmen; Ysunza, Pablo Antonio; Sarre, Pilar; Morales, Santiago; Sterling, Mariana


    Mentoring programs can boost Speech & Language (SL) pathologists' satisfaction about their clinical skills, increasing their professional competence. A quality induction program provides a bridge for an efficient and comfortable transition between theoretical knowledge and clinical practice in front of clients. This transition can be especially difficult when the SL pathologist confronts patients with cleft palate. To study whether a mentoring program can improve SL Pathology students' performance for treating patients with cleft palate. 18 SL Pathology students coursing the third year of a SL Pathology graduate program volunteered for participating in the study. The students were divided in two groups. All SL students from both groups were equally supervised. The students were followed for two semesters during their participation in the SL Pathology intervention for patients with cleft palate. The only difference between the students from each group was that one group (active group) was mentored by an experienced SLP who had previously received specific training to become a mentor. All SL students were assessed at the onset and at the end of the study. The assessment was performed through an analysis according to a previously validated scale (Learning Continuum of Speech & Language pathologists). A Wilcoxon test demonstrated a significant improvement (P<0.05) in the levels of The Learning Continuum of Speech & Language Pathologists at the end of the follow-up period in both groups of students. When the levels of performance at the end were compared between groups, a Mann Whitney test demonstrated a significant difference (P<0.05). The students included in the active group who were receiving additional mentoring besides the usual clinical supervision, showed a greater improvement as compared with the students from the control group. Learning how to conduct an adequate and effective intervention in cleft palate patients from an integral stand point is not easy for

  12. Adequacy of depression treatment among college students in the United States. (United States)

    Eisenberg, Daniel; Chung, Henry


    There is no published evidence on the adequacy of depression care among college students and how this varies by subpopulations and provider types. We estimated the prevalence of minimally adequate treatment among students with significant past-year depressive symptoms. Data were collected via a confidential online survey of a random sample of 8488 students from 15 colleges and universities in the 2009 Healthy Minds Study. Depressive symptoms were assessed by the Patient Health Questionnaire-2, adapted to a past-year time frame. Students with probable depression were coded as having received minimally adequate depression care based on the criteria from Wang and colleagues (2005). Minimally adequate treatment was received by only 22% of depressed students. The likelihood of minimally adequate treatment was similarly low for both psychiatric medication and psychotherapy. Minimally adequate care was lower for students prescribed medication by a primary care provider as compared to a psychiatrist (Pstudents were less likely to receive depression care (Pdepression care is a significant problem in the college population. Solutions will likely require greater availability of psychiatry care, better coordination between specialty and primary care using collaborative care models, and increased efforts to retain students in psychotherapy.

  15. Demographic and behavioural correlates of six sexting behaviours among Australian secondary school students. (United States)

    Patrick, Kent; Heywood, Wendy; Pitts, Marian K; Mitchell, Anne


    Background There has been increasing attention on assessing rates of sexting in adolescents and of the potential negative effects of the behaviour. Our aim was to assess rates and correlates of sexting in Australian students in years10, 11 and 12. The current study was part of The Fifth National Survey of Australian Secondary Students and Sexual Health and reports on responses of 2114 students (811 male, 1303 female). Sexting was assessed using six items: sending a sexually explicit written text message; receiving a sexually explicit text message; sending a sexually explicit nude or nearly nude photo or video of themselves; sending a sexually explicit nude or nearly nude photo or video of someone else; receiving a sexually explicit nude or nearly nude photo or video of someone else; and using a social media site for sexual reasons. Approximately half of the students had received (54%, 1139/2097) or sent (43%, 904/2107) a sexually explicit written text message. Sexually explicit images had been received by 42% (880/2098) of students, one in four students had sent a sexually explicit image of themselves (26%, 545/2102) and one in 10 had sent a sexually explicit image of someone else (9%, 180/2095). Finally, 22% (454/2103) of students had used social media for sexual reasons. Sexting was associated with several correlates. Sexting was relatively common in this sample of year 10, 11 and 12 Australian students, particularly among older students, those who are sexually active, and those who use recreational substances.

  16. The Issues of the Management of Receivables: Lithuanian Case

    Directory of Open Access Journals (Sweden)

    Remeikiene Rita


    Full Text Available Constant changes in business environment determine the significance of receivables to business. The analysis of the current situation in Lithuania has revealed that a substantial part of business enterprises are facing the problem of overdue receivables. This issue emerged as extremely topical after the beginning of the economic crisis in 2008. A number of scientific studies confirmed that the level of receivables has a significant impact not only on smooth business operation but also on operational results and serves as the cause of numerous economic and social problems, faced by both business enterprises and the state. Rising level of receivables determines slower recovery of total economics because it has a negative impact on the sustainability of the public sector of the country. In addition, the scientists highlight economic problems such as production capacity losses, general decrease in competitiveness and failure to satisfy the debt claims. The social problems include the increase in unemployment rate, fall of living standards, dissatisfaction with poor economics of the country and uncertainty about the future. The aim of this article is to analyse the impact of receivables on business in Lithuania. The methods of the research include scientific literature analysis and statistical data analysis.

  17. Middle school students' learning about genetic inheritance through on-line scaffolding supports (United States)

    Manokore, Viola

    The main goal of school science is to enable learners to become scientifically literate through their participation in scientific discourses (McNeill & Krajcik, 2009). One of the key elements of scientific discourses is the ability to construct scientific explanations that consist of valid claims supported by appropriate evidence (e.g., McNeill & Krajcik, 2006, Sadler, 2004; Sandoval & Reiser, 2004). Curricula scaffolds may help students construct scientific explanations and achieve their learning goals. This dissertation study is part of a larger study designed to support fifth through seventh grade students' learning about genetic inheritance through curricula scaffolds. Seventh grade students in this study interacted with a Web Based Inquiry Science Environment (WISE) unit called "From Genotype to Phenotype" that had curricula scaffolds. Informed by the Scaffolded Knowledge Integration, two versions of the unit were developed around concepts on genetic inheritance. Version one of the units was explicit on explaining to students how to make a claim and support it with appropriate evidence. Although the science concepts covered were the same, Version two was not explicit on claims and evidence use. Embedded in the units were scaffolding supports in the form of prompts. This dissertation study explored students' responses to the scaffolding support prompts using a knowledge integration (KI) rubric as described by Linn and His (2000). Two teachers, each with about 150 students in five classes of about 25 each, participated in the study. Each teacher had three classes of students that received a version one and the other two classed received version two of "From Genotype to Phenotype" unit. Using the Statistical Package for Social Scientists (SPSS), I explored whether students' scores, as measured by the KI rubric, varied by the unit version the students received or by the teacher they had. The findings suggested that the two versions of the unit were equally

    de Fornasari, Margareth Lage Leite; Dos Santos Sens, Yvoty Alves


    The purpose of the study was to verify the effects of replacing phosphorus-containing food additives with foods without additives on phosphatemia in end-stage renal disease (ESRD) patients. Randomized clinical trial. Adult patients on hemodialysis for ≥6 months at a single center. A total of 134 patients with phosphorus levels of >5.5 mg/dL were included and were randomized into an intervention group (n = 67) and a control group (n = 67). The IG received individual orientation to replace processed foods that have phosphorus additives with foods of similar nutritional value without these additives. The CG received only the nutritional orientation given before the study. Clinical laboratory data, nutritional status, energy and protein intake, and normalized protein nitrogen appearance (nPNA) were evaluated at the beginning of the study and after 90 days. There was no initial difference between the groups in terms of serum phosphorus levels, nutritional status, and energy intake. After 3 months, there was a decline in phosphorus levels in the IG (from 7.2 ± 1.4 to 5.0 ± 1.3 mg/dL, P food additives with foods without additives reduced serum phosphorus without interfering in the nutritional status of ESRD patients.

  19. Asymmetric Hardware Distortions in Receive Diversity Systems: Outage Performance Analysis

    KAUST Repository

    Javed, Sidrah; Amin, Osama; Ikki, Salama S.; Alouini, Mohamed-Slim


    This paper studies the impact of asymmetric hardware distortion (HWD) on the performance of receive diversity systems using linear and switched combining receivers. The asymmetric attribute of the proposed model motivates the employment of improper Gaussian signaling (IGS) scheme rather than the traditional proper Gaussian signaling (PGS) scheme. The achievable rate performance is analyzed for the ideal and non-ideal hardware scenarios using PGS and IGS transmission schemes for different combining receivers. In addition, the IGS statistical characteristics are optimized to maximize the achievable rate performance. Moreover, the outage probability performance of the receive diversity systems is analyzed yielding closed form expressions for both PGS and IGS based transmission schemes. HWD systems that employ IGS is proven to efficiently combat the self interference caused by the HWD. Furthermore, the obtained analytic expressions are validated through Monte-Carlo simulations. Eventually, non-ideal hardware transceivers degradation and IGS scheme acquired compensation are quantified through suitable numerical results.

  1. The effects of brief individual cognitive behavioural therapy for depression and homesickness among international students in Malaysia. (United States)

    Saravanan, Coumaravelou; Alias, Alizi; Mohamad, Mardiana


    Students who go to other countries for higher education face various psychological problems, particularly homesickness and depression. The objectives of this study were to: (a) identify differences between students who did and did not receive brief individual cognitive behavioural therapy (CBT) for depression to reduce homesickness; (b) identify whether brief individual CBT for depression reduces the level of homesickness in students between pre-, post- and follow-up assessment; and (c) compare the scores of students experiencing only homesickness and those experiencing both homesickness and depression. The sample consisted of 520 first-year undergraduate international students. The experimental group contained students who were diagnosed with depression and homesickness and received seven sessions of brief individual CBT for depression to reduce homesickness. The control group contained students who were diagnosed with depression and homesickness and received one session of advice and suggestions. The comparison group contained students who experienced only homesickness and did not receive any interventions. The study used the comparison group to determine if an interaction effect existed between students experiencing only homesickness and students experiencing both homesickness and depression. Students who received brief individual CBT displayed a significant reduction in their homesickness and depression scores compared to the scores of students in the control group. Students who experienced only homesickness exhibited a significant reduction in the scores on homesickness in the post-assessment compared to the control group's post-assessment homesickness scores. The results of this study cannot be generalized as data were collected from three universities in Malaysia. The follow-up assessment was conducted six months after the post-assessment, which also limits generalizability beyond six months. Overall, homesickness is considered a normal reaction. Brief

  3. Preceptorship: using an ethical lens to reflect on the unsafe student. (United States)

    Earle-Foley, Vicki; Myrick, Florence; Luhanga, Florence; Yonge, Olive


    Patient safety has become a worldwide health concern, and health care professionals have a moral and ethical responsibility to promote patient safety. The clinical education of many health care professionals often involves a preceptorship or field experience wherein students are assigned to work one-to-one with a preceptor or field educator so that they can be socialized into the profession and receive a reality-oriented experience. Health care professionals who accept the responsibility of being a preceptor face additional workload and stress, especially when the students to whom they are assigned are not meeting the expectations of safe, professional practice. Taking a stand against unsafe students is an important way for preceptors to promote patient safety. Given the nature of the stress and the inherent ethical issues associated with precepting an unsafe student, it is useful to examine this experience through an ethical lens. Included in this article is a brief overview of preceptorship as a model of clinical education, together with a discussion of the nature of the ethical decisions that preceptors face when precepting an unsafe student. Ethical theories, namely, virtue ethics and utilitarianism, are also explored and serve to provide the ethical lens through which preceptors can reflect upon their experiences with unsafe students.

    Schwartz, Jacob


    An improved long-life design for solar energy receivers provides for greatly reduced thermally induced stress and permits the utilization of less expensive heat exchanger materials while maintaining receiver efficiencies in excess of 85% without undue expenditure of energy to circulate the working fluid. In one embodiment, the flow index for the receiver is first set as close as practical to a value such that the Graetz number yields the optimal heat transfer coefficient per unit of pumping energy, in this case, 6. The convective index for the receiver is then set as closely as practical to two times the flow index so as to obtain optimal efficiency per unit mass of material.

    Stella Regina Martins

    Full Text Available ABSTRACT Objective: To determine the level of agreement with effective tobacco control measures recommended by the World Health Organization and to assess the attitudes toward, knowledge of, and beliefs regarding smoking among third-year medical students at University of São Paulo School of Medicine, located in the city of São Paulo, Brazil. Methods: Between 2008 and 2012, all third-year medical students were invited to complete a self-administered questionnaire based on the Global Health Professionals Student Survey and its additional modules. Results: The study sample comprised 556 students. The level of agreement with the World Health Organization recommendations was high, except for the components “received smoking cessation training” and “raising taxes is effective to reduce the prevalence of smoking”. Most of the students reported that they agree with banning tobacco product sales to minors (95%, believe that physicians are role models to their patients (84%, and believe that they should advise their patients to quit cigarette smoking (96% and using other tobacco products (94%. Regarding smoking cessation methods, most of the students were found to know more about nicotine replacement therapy than about non-nicotine therapies (93% vs. 53%. Only 37% of the respondents were aware of the importance of educational antismoking materials, and only 31% reported that they believe in the effectiveness of encouraging their patients, during medical visits. In our sample, the prevalence of current cigarette smoking was 5.23%; however, 43.82% of the respondents reported having experimented with water-pipe tobacco smoking. Conclusions: Our results revealed the need to emphasize to third-year medical students the importance of raising the prices of and taxes on tobacco products. We also need to make students aware of the dangers of experimenting with tobacco products other than cigarettes, particularly water-pipe tobacco smoking.

  11. Dental students' part-time jobs in dental practices in the Netherlands. (United States)

    Poorterman, J H G; Dikkes, B T; Brand, H S


    In the Netherlands, the Individual Health Care Professions Act (IHCP Act) allows dental students, amongst other non-qualified individuals, to work under certain conditions in a dental practice. The aim of the study was to determine how many dental students have part-time employment in dental practice and which professional tasks they carry out. We also asked the dental students their opinion about the IHCP Act. All the enrolled dental students at the Academic Centre for Dentistry Amsterdam (ACTA) in the Netherlands received a questionnaire by e-mail. Within 1 month, two reminders were sent. The response was 44% (427 students). Of the responding students, 71% had paid employment in addition to their study. Twenty-five per cent of all students worked in a dental practice, usually 8 h a week. Study year and age were positively related to working part-time in dental practice. Activities frequently performed were providing chair side assistance, giving oral hygiene instruction, fluoride applications, scaling and root planning. The self-reported knowledge about the IHCP Act was positively related to study year and working in a dental practice. Hardly any information about the requirements of the IHCP Act with regard to delegation of tasks was provided by the employer. Many Dutch dental students work in a dental practice, taking over a variety of tasks. Although the self-reported knowledge about the IHCP Act was relatively high, many dental students expressed the need for more detailed information about the legal aspects of their tasks.

    Full Text Available A Review of: Rivera, E. (2017. Flipping the classroom in freshman English library instruction: A comparison study of a flipped class versus a traditional lecture method. New Review of Academic Librarianship, 23(1, 18-27. Abstract Objective – To determine whether a flipped classroom approach to freshman English information literacy instruction improves student learning outcomes. Design – Quasi-experimental. Setting – Private suburban university with 7,000 graduate and undergraduate students. Subjects – First-year English students. Methods – Students in six sections of first-year “English 2” received library instruction; three sections received flipped library instruction and three sections received traditional library instruction. Students in the flipped classroom sections were assigned two videos to watch before class, as an introduction to searching the Library’s catalog and key academic databases. These students were also expected to complete pre-class exercises that allowed them to practice what they learned through the videos. The face-to-face classes involved a review of the flipped materials alongside additional activities. Works cited pages from the students’ final papers were collected from all six sections, 31 from the flipped sections and 34 from the non-flipped sections. A rubric was used to rate the works cited pages. The rubric was based on the Association of College and Research Libraries’ Information Literacy Competency Standards for Higher Education (ACRL, 2000, Standard Two, Outcome 3a, and included three criteria: “authority,” “timeliness,” and “variety.” Each criterion was rated at one of three levels: “exemplary,” “competent,” or “developing.” Main Results – Works cited pages from the students who received non-flipped instruction were more likely to score “exemplary” for at least one of the three criteria when compared to works

  13. Training in Decision-making Strategies: An approach to enhance students' competence to deal with socio-scientific issues (United States)

    Gresch, Helge; Hasselhorn, Marcus; Bögeholz, Susanne


    Dealing with socio-scientific issues in science classes enables students to participate productively in controversial discussions concerning ethical topics, such as sustainable development. In this respect, well-structured decision-making processes are essential for elaborate reasoning. To foster decision-making competence, a computer-based programme was developed that trains secondary school students (grades 11-13) in decision-making strategies. The main research question is: does training students to use these strategies foster decision-making competence? In addition, the influence of meta-decision aids was examined. Students conducted a task analysis to select an appropriate strategy prior to the decision-making process. Hence, the second research question is: does combining decision-making training with a task analysis enhance decision-making competence at a higher rate? To answer these questions, 386 students were tested in a pre-post-follow-up control-group design that included two training groups (decision-making strategies/decision-making strategies combined with a task analysis) and a control group (decision-making with additional ecological information instead of strategic training). An open-ended questionnaire was used to assess decision-making competence in situations related to sustainable development. The decision-making training led to a significant improvement in the post-test and the follow-up, which was administered three months after the training. Long-term effects on the quality of the students' decisions were evident for both training groups. Gains in competence when reflecting upon the decision-making processes of others were found, to a lesser extent, in the training group that received the additional meta-decision training. In conclusion, training in decision-making strategies is a promising approach to deal with socio-scientific issues related to sustainable development.

    Miri Shonfeld


    Full Text Available The perceived contribution of science education online course to pre-service students (N=121 from diverse backgrounds - students with learning disabilities (25 LD students, 28 excellent students and 68 average students is presented in this five years research. During the online course students were asked to choose a scientific subject; to map it and to plan teaching activities; to carry out the proposed activities with students in a classroom experience; and to reflect the process. The assumption was that adapting the online course by using information and communication technology following formative assessment will improve students' self-learning ability as well as broaden their science knowledge, their lab performance and teaching skills. Data were collected using quantitative and qualitative tools including: pre and post questionnaires and nine (three students from each group depth interviews upon completion of the course. Findings, based on students` perceived evaluation, pinpointed on the advantages of the online course for students of the three groups. LD students’ achievements were not inferior to those of their peers, excellent students and average students. Yet, it carefully reports on a slight but explicitly marginal perceived evaluation of the LD students in comparison to excellent students and average students regarding: forum participation, authentic task and water lab performance. The article discusses the affordance of the online course via additional features that can be grouped into two categories: knowledge construction and flexibility in time, interaction and knowledge. Further research is suggested to extend the current study by examine the effect of other courses and different contents and by considering various evaluation methods of online courses, such as: observation, the think aloud, text and tasks analysis, and reflection.

  20. Resource-oriented coaching for reduction of examination-related stress in medical students: an exploratory randomized controlled trial

    Directory of Open Access Journals (Sweden)

    Kötter T


    Full Text Available Thomas Kötter,1 Frank Niebuhr2 1Institute of Social Medicine and Epidemiology, 2Institute of Family Medicine, University of Lübeck, Lübeck, Germany Introduction: The years spent in acquiring medical education is considered a stressful period in the life of many students. Students whose mental health deteriorates during this long period of study are less likely to become empathic and productive physicians. In addition to other specific stressors, academic examinations seem to further induce medical school-related stress and anxiety. Combined group and individual resource-oriented coaching early in medical education might reduce examination-related stress and anxiety and, consequently, enhance academic performance. Good quality evidence, however, remains scarce. In this study, therefore, we explored the question of whether coaching affects examination-related stress and health in medical students.Methods: We conducted a randomized controlled trial. Students who registered for the first medical academic examination in August 2014 at the University of Lübeck were recruited and randomized into three groups. The intervention groups 1 and 2 received a 1-hour psychoeducative seminar. Group 1 additionally received two 1-hour sessions of individual coaching during examination preparation. Group 3 served as a control group. We compared changes in self-rated general health (measured by a single item, anxiety and depression (measured by the hospital anxiety and depression scale, as well as medical school stress (measured by the perceived medical school stress instrument. In order to further investigate the influence of group allocation on perceived medical school stress, we conducted a linear regression analysis.Results: We saw a significant deterioration of general health and an increase in anxiety and depression scores in medical students while preparing for an examination. We found a small, but statistically significant, effect of group allocation on

  1. Comparison of four teaching methods on Evidence-based Practice skills of postgraduate nursing students. (United States)

    Fernandez, Ritin S; Tran, Duong Thuy; Ramjan, Lucie; Ho, Carey; Gill, Betty


    The aim of this study was to compare four teaching methods on the evidence-based practice knowledge and skills of postgraduate nursing students. Students enrolled in the Evidence-based Nursing (EBN) unit in Australia and Hong Kong in 2010 and 2011 received education via either the standard distance teaching method, computer laboratory teaching method, Evidence-based Practice-Digital Video Disc (EBP-DVD) teaching method or the didactic classroom teaching method. Evidence-based Practice (EBP) knowledge and skills were evaluated using student assignments that comprised validated instruments. One-way analysis of covariance was implemented to assess group differences on outcomes after controlling for the effects of age and grade point average (GPA). Data were obtained from 187 students. The crude mean score among students receiving the standard+DVD method of instruction was higher for developing a precise clinical question (8.1±0.8) and identifying the level of evidence (4.6±0.7) compared to those receiving other teaching methods. These differences were statistically significant after controlling for age and grade point average. Significant improvement in cognitive and technical EBP skills can be achieved for postgraduate nursing students by integrating a DVD as part of the EBP teaching resources. The EBP-DVD is an easy teaching method to improve student learning outcomes and ensure that external students receive equivalent and quality learning experiences. Copyright © 2012 Elsevier Ltd.

  2. Hydrogen sulfide production by sulfate-reducing bacteria utilizing additives eluted from plastic resins. (United States)

    Tsuchida, Daisuke; Kajihara, Yusuke; Shimidzu, Nobuhiro; Hamamura, Kengo; Nagase, Makoto


    In the present study it was demonstrated that organic additives eluted from plastic resins could be utilized as substrates by sulfate-reducing bacteria. Two laboratory-scale experiments, a microcosm experiment and a leaching experiment, were conducted using polyvinyl chloride (PVC) as a model plastic resin. In the former experiment, the conversion of sulfate to sulfide was evident in microcosms that received plasticized PVC as the sole carbon source, but not in those that received PVC homopolymer. Additionally, dissolved organic carbon accumulated only in microcosms that received plasticized PVC, indicating that the dissolved organic carbon originated from additives. In the leaching experiment, phenol and bisphenol A were found in the leached solutions. These results suggest that the disposal of waste plastics in inert waste landfills may result in the production of H(2)S.

  6. Interventions to reduce stress in university students: a review and meta-analysis. (United States)

    Regehr, Cheryl; Glancy, Dylan; Pitts, Annabel


    Recent research has revealed concerning rates of anxiety and depression among university students. Nevertheless, only a small percentage of these students receive treatment from university health services. Universities are thus challenged with instituting preventative programs that address student stress and reduce resultant anxiety and depression. A systematic review of the literature and meta-analysis was conducted to examine the effectiveness of interventions aimed at reducing stress in university students. Studies were eligible for inclusion if the assignment of study participants to experimental or control groups was by random allocation or parallel cohort design. Retrieved studies represented a variety of intervention approaches with students in a broad range of programs and disciplines. Twenty-four studies, involving 1431 students were included in the meta-analysis. Cognitive, behavioral and mindfulness interventions were associated with decreased symptoms of anxiety. Secondary outcomes included lower levels of depression and cortisol. Included studies were limited to those published in peer reviewed journals. These studies over-represent interventions with female students in Western countries. Studies on some types of interventions such as psycho-educational and arts based interventions did not have sufficient data for inclusion in the meta-analysis. This review provides evidence that cognitive, behavioral, and mindfulness interventions are effective in reducing stress in university students. Universities are encouraged to make such programs widely available to students. In addition however, future work should focus on developing stress reduction programs that attract male students and address their needs. Copyright © 2012 Elsevier B.V. All rights reserved.

    Sontag-Padilla, Lisa; Woodbridge, Michelle W; Mendelsohn, Joshua; D'Amico, Elizabeth J; Osilla, Karen Chan; Jaycox, Lisa H; Eberhart, Nicole K; Burnam, Audrey M; Stein, Bradley D


    Unmet need for mental health treatment among college students is a significant public health issue. Despite having access to campus mental health providers and insurance to cover services, many college students do not receive necessary services. This study examined factors influencing college students' use of mental health services. Online survey data for 33,943 students and 14,018 staff and faculty at 39 college campuses in California were analyzed by using logistic regressions examining the association between students' use of mental health services and student characteristics, campus environment, and the presence of a formal network of campus mental health clinics. Nineteen percent of students reported current serious psychological distress in the past 30 days, and 11% reported significant mental health-related academic impairment in the past year. Twenty percent reported using mental health services while at their current college, 10% by using campus services and 10% off-campus services. Students on campuses with a formal network of mental health clinics were more likely than students at community colleges to receive mental health services (odds ratio [OR] range=1.68-1.69), particularly campus services (OR=3.47-5.72). Students on campuses that are supportive of mental health issues were more likely to receive mental health services (OR=1.22), particularly on campus (OR=1.65). Students with active (versus low) coping skills were consistently more likely to use mental health services. Establishing more campus mental health clinics, fostering supportive campus environments, and increasing students' coping skills may reduce unmet need for mental health services among college students.

    The aim of this study was to evaluate the relationship between life satisfaction and quality of life of nursing students. This descriptive and cross-sectional study was conducted with a research population of 396 nursing students who received education at a school of nursing. The research data were collected between May and June of the 2007-2008 academic year. The data collection tools included "Student Description Form," Life Satisfaction Scale, and WHOQOL-BREF (TR) Quality of Life (QOL) Scale. The mean score of life satisfaction was 22.90 ± 5.74. Participants' QOL mean scores were 67.16 ± 15.29 in the physical domain, 64.33 ± 14.72 in the psychological domain, 62.81 ± 19.12 in the social relationships domain, and 60.59 ± 12.59 in the environmental domain. There was a significant correlation between life satisfaction and the four main domains of quality of life scores (P life satisfaction and quality of life among nursing students. In addition, it was determined that being a nursing student had a positive effect on students' life satisfaction and quality of life. Therefore, the education system is recommended to be redesigned in such a way as to make students more active and to improve their life satisfaction and quality of life. © 2013 Wiley Publishing Asia Pty Ltd.

  14. Pain management in Jordan: nursing students' knowledge and attitude. (United States)

    Al Khalaileh, Murad; Al Qadire, Mohammad

    Pain management requires knowledgeable and trained nurses. Because nursing students are the nurses of the future, it is important to ensure that students receive adequate education about pain management in nursing schools. The purpose of this study is to evaluate nursing students' knowledge and attitudes regarding pain management. A cross-sectional survey was used. The sample comprised 144 students from three nursing colleges in Jordan. Sixty-one percent were female and the average age was 21.6 years (SD 1.7). The students' Knowledge and Attitudes Survey Regarding Pain was used. The rate of correct answers ranged from 11.1% to 64%. Students showed a low level of knowledge regarding pain management-the average score was just 16 (SD 5.11) out of 40. Students were weak in their knowledge of pain medications pharmacology (actions and side effects). Less than half of students (47.9%) recognised that pain may be present, even when vital signs are normal and facial expressions relaxed. Finally, students showed negative attitudes towards pain management, believing that patients should tolerate pain as much as they can before receiving opioids; almost half (48%) of students agreed that patients' pain could be managed with placebo rather than medication. In conclusion, Jordanian nursing students showed lower levels of pain knowledge compared with other nursing students around the world. This study underlines the need to include pain-management courses throughout undergraduate nursing curricula in Jordan.

  15. Digital terrestrial broadcasting receiver in the U.K; Eikoku chijoha digital hoso jushinki

    Energy Technology Data Exchange (ETDEWEB)



    Digital terrestrial broadcasting is broadcasted in parallel with existing UHF analog broadcasting, whereas each of allocated channel frequencies can transmit five to six programs simultaneously. Each home can receive a number of programs with the existing antenna without a need of installing a new satellite antenna or cable. Among the countries of the world running forward to digitization of broadcasting all at once, the U.K. develops advancing movements and leads the world by starting the digital terrestrial broadcasting. In addition to the digitized broadcasting of conventional analog broadcasting programs, the `Ondigitals` (broadcasting operators) have started newly the pay broadcasting. Toshiba has been selected as one of the six developers and manufacturers of digital terrestrial broadcasting receivers, and has developed the digital terrestrial broadcasting receiver DTB2000. For the modulation system, the orthogonal frequency division multiplex (OFDM) was chosen as a system being strong against ghost and most suitable for digital terrestrial broadcasting. In addition, the receiver is equipped with software download function by using the broadcasting waves, and the common interface being the communication specification specified in the DVB (digital video broadcasting) to provide future function expandability.

  16. Turbo Decision Aided Receivers for Clipping Noise Mitigation in Coded OFDM

    Directory of Open Access Journals (Sweden)

    Declercq David


    Full Text Available Abstract Orthogonal frequency division multiplexing (OFDM is the modulation technique used in most of the high-rate communication standards. However, OFDM signals exhibit high peak average to power ratio (PAPR that makes them particularly sensitive to nonlinear distortions caused by high-power amplifiers. Hence, the amplifier needs to operate at large output backoff, thereby decreasing the average efficiency of the transmitter. One way to reduce PAPR consists in clipping the amplitude of the OFDM signal introducing an additional noise that degrades the overall system performance. In that case, the receiver needs to set up an algorithm that compensates this clipping noise. In this paper, we propose three new iterative receivers with growing complexity and performance that operate at severe clipping: the first and simplest receiver uses a Viterbi algorithm as channel decoder whereas the other two implement a soft-input soft-output (SISO decoder. Each soft receiver is analyzed through EXIT charts for different mappings. Finally, the performances of the receivers are simulated on both short time-varying channel and AWGN channel.

    Gonçalves Luzia


    Full Text Available Abstract Background This paper describes the socio-economic profile of medical students in the 1998/99 academic year at the Universidade Eduardo Mondlane (UEM Medical Faculty in Maputo. It aims to identify their social and geographical origins in addition to their expectations and difficulties regarding their education and professional future. Methods The data were collected through a questionnaire administered to all medical students at the faculty. Results Although most medical students were from outside Maputo City and Maputo Province, expectations of getting into medical school were already associated with a migration from the periphery to the capital city, even before entering medical education. This lays the basis for the concentration of physicians in the capital city once their term of compulsory rural employment as junior doctors is completed. The decision to become a doctor was taken at an early age. Close relatives, or family friends seem to have been an especially important variable in encouraging, reinforcing and promoting the desire to be a doctor. The academic performance of medical students was dismal. This seems to be related to several difficulties such as lack of library facilities, inadequate financial support, as well as poor high school preparation. Only one fifth of the students reported receiving financial support from the Mozambican government to subsidize their medical studies. Conclusion Medical students seem to know that they will be needed in the public sector, and that this represents an opportunity to contribute to the public's welfare. Nevertheless, their expectations are, already as medical students, to combine their public sector practice with private medical work in order to improve their earnings.

  2. An anatomy precourse enhances student learning in veterinary anatomy. (United States)

    McNulty, Margaret A; Stevens-Sparks, Cathryn; Taboada, Joseph; Daniel, Annie; Lazarus, Michelle D


    Veterinary anatomy is often a source of trepidation for many students. Currently professional veterinary programs, similar to medical curricula, within the United States have no admission requirements for anatomy as a prerequisite course. The purpose of the current study was to evaluate the impact of a week-long precourse in veterinary anatomy on both objective student performance and subjective student perceptions of the precourse educational methods. Incoming first year veterinary students in the Louisiana State University School of Veterinary Medicine professional curriculum were asked to participate in a free precourse before the start of the semester, covering the musculoskeletal structures of the canine thoracic limb. Students learned the material either via dissection only, instructor-led demonstrations only, or a combination of both techniques. Outcome measures included student performance on examinations throughout the first anatomy course of the professional curriculum as compared with those who did not participate in the precourse. This study found that those who participated in the precourse did significantly better on examinations within the professional anatomy course compared with those who did not participate. Notably, this significant improvement was also identified on the examination where both groups were exposed to the material for the first time together, indicating that exposure to a small portion of veterinary anatomy can impact learning of anatomical structures beyond the immediate scope of the material previously learned. Subjective data evaluation indicated that the precourse was well received and students preferred guided learning via demonstrations in addition to dissection as opposed to either method alone.

    Dayal, Ashlesha K; Fisher, Nelli; Magrane, Diane; Goffman, Dena; Bernstein, Peter S; Katz, Nadine T


    To determine the relationship between simulation training for vaginal delivery maneuvers and subsequent participation in live deliveries during the clinical rotation and to assess medical students' performance and confidence in vaginal delivery maneuvers with and without simulation training. Medical students were randomized to receive or not to receive simulation training for vaginal delivery maneuvers on a mannequin simulator at the start of a 6-week clerkship. Both groups received traditional didactic and clinical teaching. One researcher, blinded to randomization, scored student competence of delivery maneuvers and overall delivery performance on simulator. Delivery performance was scored (1-5, with 5 being the highest) at weeks 1 and 5 of the clerkship. Students were surveyed to assess self-confidence in the ability to perform delivery maneuvers at weeks 1 and 5, and participation in live deliveries was evaluated using student obstetric patient logs. Thirty-three students were randomized, 18 to simulation training [simulation group (SIM)] and 15 to no simulation training [control group (CON)]. Clerkship logs demonstrated that SIM students participated in more deliveries than CON students (9.8 +/- 3.7 versus 6.2 +/- 2.8, P < 0.005). SIM reported increased confidence in ability to perform a vaginal delivery, when compared with CON at the end of the clerkship (3.81 +/- 0.83 versus 3.00 +/- 1.0, respectively, P < 0.05). The overall delivery performance score was significantly higher in SIM, when compared with CON at week 1 (3.94 +/- 0.94 versus 2.07 +/- 1.22, respectively, P < 0.001) and week 5 (4.88 +/- 0.33 versus 4.31 +/- 0.63, P < 0.001) in the simulated environment. Students who receive simulation training participate more actively in the clinical environment during the course of the clerkship. Student simulation training is beneficial to learn obstetric skills in a minimal risk environment, demonstrate competency with maneuvers, and translate this competence

    Full Text Available This research aimed at investigating students’ development of learning integer concept and integer addition. The investigation was based on analyzing students’ works in solving the given mathematical problems in each instructional activity designed based on Realistic Mathematics Education (RME levels. Design research was chosen to achieve and to contribute in developing a local instruction theory for teaching and learning of integer concept and integer addition. In design research, the Hypothetical Learning Trajectory (HLT plays important role as a design and research instrument. It was designed in the phase of preliminary design and tested to three students of grade six OASIS International School, Ankara – Turkey. The result of the experiments showed that temperature in the thermometer context could stimulate students’ informal knowledge of integer concept. Furthermore, strategies and tools used by the students in comparing and relating two temperatures were gradually be developed into a more formal mathematics. The representation of line inside thermometer which then called the number line could bring the students to the last activity levels, namely rules for adding integer, and became the model for more formal reasoning. Based on these findings, it can be concluded that students’ learning integer concept and integer addition developed through RME levels.Keywords: integer concept, integer addition, Realistic Mathematics Education DOI:

  13. Live lecture versus video-recorded lecture: are students voting with their feet? (United States)

    Cardall, Scott; Krupat, Edward; Ulrich, Michael


    In light of educators' concerns that lecture attendance in medical school has declined, the authors sought to assess students' perceptions, evaluations, and motivations concerning live lectures compared with accelerated, video-recorded lectures viewed online. The authors performed a cross-sectional survey study of all first- and second-year students at Harvard Medical School. Respondents answered questions regarding their lecture attendance; use of class and personal time; use of accelerated, video-recorded lectures; and reasons for viewing video-recorded and live lectures. Other questions asked students to compare how well live and video-recorded lectures satisfied learning goals. Of the 353 students who received questionnaires, 204 (58%) returned responses. Collectively, students indicated watching 57.2% of lectures live, 29.4% recorded, and 3.8% using both methods. All students have watched recorded lectures, and most (88.5%) have used video-accelerating technologies. When using accelerated, video-recorded lecture as opposed to attending lecture, students felt they were more likely to increase their speed of knowledge acquisition (79.3% of students), look up additional information (67.7%), stay focused (64.8%), and learn more (63.7%). Live attendance remains the predominant method for viewing lectures. However, students find accelerated, video-recorded lectures equally or more valuable. Although educators may be uncomfortable with the fundamental change in the learning process represented by video-recorded lecture use, students' responses indicate that their decisions to attend lectures or view recorded lectures are motivated primarily by a desire to satisfy their professional goals. A challenge remains for educators to incorporate technologies students find useful while creating an interactive learning culture.

  16. Teaching medical students cancer risk reduction nutrition counseling using a multimedia program. (United States)

    Kolasa, K M; Jobe, A C; Miller, M G; Clay, M C


    There are many barriers to medical students receiving education about the linkage between nutrition and cancer, including the lack of role models and teachers and insufficient curricular time. We tested the use of a multimedia program as a possible solution to teaching diet-risk assessment and counseling skills. Images of Cancer Prevention, The Nutrition Link is a CD-ROM multimedia program that was developed and evaluated by 147 medical students. Pre-use and post-use surveys, computer log files, and recorded response sessions were used to determine the learner's 1) ease in using the program, 2) attitudes about the treatment of the content, 3) knowledge gain, and 4) attitudes about the role of physicians in nutrition assessment and counseling for cancer risk reduction. Students improved their knowledge of dietary guidelines for cancer risk reduction and made positive changes in their attitudes toward the role of physicians in dietary counseling. However, most students reported that they would not use the program unless it was required that they do so. The multimedia program was successful; it affected students' knowledge and attitudes concerning nutrition as a modifiable risk factor for some cancers. In addition, the design and delivery of the multimedia product was positively reviewed by the students for ease of access, message design, individualized instruction, and flexibility. Despite these favorable ratings, it was not clear that students would use the program unless required to do so.

  17. Do networking activities outside of the classroom protect students against being bullied? A field study with students in secondary school settings in Germany. (United States)

    Blickle, Gerhard; Meurs, James A; Schoepe, Christine


    Research has shown that having close relationships with fellow classmates can provide a buffer for students against bullying and the negative outcomes associated with it. But, research has not explicitly examined the potential benefits of social networking behaviors outside of the classroom for those who could be bullied. This study addresses this gap and finds that, although a bullying climate in the classroom increases overall bullying, students high on external networking activities did not experience an increase in the bullying they received when in a classroom with a high bullying climate. However, the same group of students reported the largest degree of received bulling under conditions of a low bullying climate. We discuss the implications of our results and provide directions for future research.

    This study was conducted to evaluate the performance of physical examination (PE) skills during our diagnostic medicine course and analyze the characteristics of the data collected to provide information for practical guidance to improve the quality of teaching. Seventy-two fourth-year medical students were enrolled in the study. All received an assessment of PE skills after receiving a 17-week formal training course and systematic teaching. Their performance was evaluated and recorded in detail using a checklist, which included 5 aspects of PE skills: examination techniques, communication and care skills, content items, appropriateness of examination sequence, and time taken. Error frequency and type were designated as the assessment parameters in the survey. The results showed that the distribution and the percentage in examination errors between male and female students and among the different body parts examined were significantly different (pexaminations was higher than in abdominal (0.867) and head, neck and nervous system examinations (0.917). Female students had a lower average error frequency than males in cardiac examinations (p = 0.041). Additionally, error in examination techniques was the highest type of error among the 5 aspects of PE skills irrespective of participant gender and assessment content (pexaminations and examination techniques may be included in the main focus of improving the teaching of diagnostics in these medical students.

  1. Format as a False Judge of Credibility: Messages from Librarians and Faculty and Student Responses

    Directory of Open Access Journals (Sweden)

    Amy E. Mark


    Full Text Available The purpose of this case study is to explore how students make sense of and respond to messages about information in higher education. This study identifies the messages students in higher education receive about information gathering, conducting research, and the credibility and authority of information sources. This research revealed that students are receiving the message from faculty that format is a stand-in for credibility. Research to date focuses on how to steer students to information privileged by the academy: academic, peer reviewed articles, and books. The voice of students is often absent. This study employs the critical framework of Paulo Freire in order to give voice to student perceptions of information.

    Pickering, Amy J; Davis, Jennifer; Blum, Annalise G; Scalmanini, Jenna; Oyier, Beryl; Okoth, George; Breiman, Robert F; Ram, Pavani K


    Handwashing is difficult in settings with limited resources and water access. In primary schools within urban Kibera, Kenya, we investigated the impact of providing waterless hand sanitizer on student hand hygiene behavior. Two schools received a waterless hand sanitizer intervention, two schools received a handwashing with soap intervention, and two schools received no intervention. Hand cleaning behavior after toilet use was monitored for 2 months using structured observation. Hand cleaning after toileting was 82% at sanitizer schools (N = 2,507 toileting events), 38% at soap schools (N = 3,429), and 37% at control schools (N = 2,797). Students at sanitizer schools were 23% less likely to have observed rhinorrhea than control students (P = 0.02); reductions in student-reported gastrointestinal and respiratory illness symptoms were not statistically significant. Providing waterless hand sanitizer markedly increased student hand cleaning after toilet use, whereas the soap intervention did not. Waterless hand sanitizer may be a promising option to improve student hand cleansing behavior, particularly in schools with limited water access.

    This study attempts to extract certain directions for the education program to provide right information by investigating knowledges, consciousnesses, and attitudes of some university students. They have a high level of knowledges among average persons on the use of radiations in order to recognize the radiation safety in daily lives including the change in national recognitions for radiations safety that is consistent with the situation in these days. The survey was performed for 528 university students from Oct. 10 to Oct. 15, 2005. The results of this survey can be summarized as follows; students who didn't get educations for the use of radiations were recorded as 415 students (80.7%) in which the reason that they didn't get such educations was 'there were no chances to receive the education' as 265 students (77.9%). The basic knowledge on the use of radiations was presented as a low level of 5.96 ± 2.90 points based on the sum of 15 points, and the consciousness on the use of radiations was investigated as 3.65 ± 0.50 points based on the sum of 5 points. In addition, the attitude on the use of radiations was investigated as 3.23 ± 0.46 points based on the sum of 5 points

    Full Text Available Nowadays, learning requires students to develop their knowledge through critical thinking. Knowledge is not just receiving the information but also interpreting the information. It requires new learning goals change the relationship between assessment and instruction. So, the lecturers need to assess the students’ ability to comprehend the materials. In addition, the lecturers have to take an active role about the purpose of the assessment and the content that is being assessed. There are many kinds of assessments used by the lecturers given to their students. For example: asking the students to do the discussion, test, questioning, observation etc. School observation tends to be familiar for the students of English Education Department of Muria Kudus University since by doing the observation they can face the real school condition. The students can observe the English teaching and learning process in the classroom. This paper focuses in AMEL (Approaches and Methods in English Language class. It discusses the application of school observation as one of the authentic assessment for English Education Department students of Muria Kudus University through exploring the approaches and methods used by Junior High School teachers in Kudus. In the end of the observation, the students have to report the discussion in form of poster presentation.

  6. Embedding international benchmarks of proficiency in English in undergraduate nursing programmes: challenges and strategies in equipping culturally and linguistically diverse students with English as an additional language for nursing in Australia. (United States)

    Glew, Paul J


    To meet the expected shortfalls in the number of registered nurses throughout the coming decade Australian universities have been recruiting an increasing number of students from culturally and linguistically diverse (CaLD) backgrounds. Given that international and domestic students who use English as an additional language (EAL) complement the number of native English speaking nursing students, they represent a valuable nurse education investment. Although university programmes are in a position to meet the education and learning needs of native English speaking nursing students, they can experience considerable challenges in effectively equipping EAL students with the English and academic language skills for nursing studies and registration in Australia. However, success in a nursing programme and in preparing for nurse registration can require EAL students to achieve substantial literacy skills in English and academic language through their engagement with these tertiary learning contexts. This paper discusses the education implications for nursing programmes and EAL students of developing literacy skills through pre-registration nursing studies to meet the English language skills standard for nurse registration and presents intervention strategies for nursing programmes that aim to build EAL student capacity in using academic English.

  7. Breaking down silos: engaging students to help fix the US health care system. (United States)

    Kumarasamy, Mathu A; Sanfilippo, Fred P


    The field of health care is becoming a team effort as patient care becomes increasingly complex and multifaceted. Despite the need for multidisciplinary education, there persists a lack of student engagement and collaboration among health care disciplines, which presents a growing concern as students join the workforce. In October 2013, the Emory-Georgia Tech Healthcare Innovation Program organized a student driven symposium entitled "US Healthcare: What's Broken and How to Fix It: The Student Perspective". The symposium engaged students from multiple disciplines to work together in addressing problems associated with US health care delivery. The symposium was organized and carried out by a diverse group of student leaders from local institutions who adopted a multidisciplinary approach throughout the planning process. The innovative planning process leading up to the symposium revealed that many of the student-discipline groups lacked an understanding of one another's role in health care, and that students were interested in learning how to work together to leverage each other's profession. The symposium was widely attended and positively received by students and faculty from the Atlanta metropolitan area, and has since helped to promote interdepartmental collaboration and multidisciplinary education across institutions. The student symposium will become an annual event and incorporate broader discipline representation, as well as a patient perspective. Proposals for additional institution-wide, multidisciplinary educational offerings are being addressed with the help of faculty and health care providers across the network. Accordingly, the implementation of student-driven symposia to engage students and stimulate institution-wide changes may be a beneficial and cost-effective means for academic health centers looking to facilitate multidisciplinary health care education.

  8. Instructor and course evaluation based on student-identified criteria. (United States)

    Jackson, M O


    Students have come to school for an education and it is their right to evaluate the quality of the education they are receiving. They should not have to demand or even ask for the privilege of saying what they think. Instructors should be providing the opportunity for evaluation by requesting that information from the students. No value judgment can be totally objective, but an instrument composed of mutually agreed upon statements should encourage the greatest possible degree of objectivity. Using one accepted form throughout the school, all students would be considering the same characteristics and traits for every instructor and course evaluated. Each instructor would receive similar information about personal performance and about the course presented. Students would be free to talk to the faculty or to add comments if they so desired; but, a questionnaire used in every course would allow and even encourage responses from every student enrolled. Faculty responsibility would not end with the preparation and implementation of an evaluation instrument. Instructors would have to let the students know their opinions are important and will be considered in curricular and instructional decisions. Faculty and students would be communicating and hopefully fulfilling the needs of and responsibilities to each other.

  14. Tomorrow's educators … today? Implementing near-peer teaching for medical students. (United States)

    Nelson, Adam J; Nelson, Sophie V; Linn, Andrew M J; Raw, Lynne E; Kildea, Hugh B; Tonkin, Anne L


    The University of Adelaide offers a six-year undergraduate medical degree with a focus on small group learning. Senior medical students had previously received limited formal training in education skills, and were identified as an underutilised teaching resource. To devise a programme in which senior students are exposed to the various facets of university teaching responsibilities and to evaluate its impact on both the tutors and the students. A six week rotation in medical education for final year medical students was designed and implemented in 2010 to involve them in the development, delivery and assessment of the 1st and 2nd year medical programme as near-peer tutors (NPTs). Two years after the rotation's implementation, voluntary evaluation of both the junior students and NPTs was undertaken through a mixed methods approach of survey and focus group. Junior students (n=358) revealed the NPTs provided non-threatening learning environments, provided helpful feedback and acted as role models. Additionally, the NPTs (n=24) reported they had consolidated prior knowledge, developed their teaching skills and expressed a desire to be more involved in teaching in the future. The implementation of NPTs in the teaching of junior medical students appears to benefit both students and their near-peer colleagues. Involvement of NPTs in all facets of medical education through this rotation stands to not only foster potential interest in an academic pathway but also equip them with a variety of transferable skills which they can draw on as future educators in their profession.

  17. Performance of two different digital evaluation systems used for assessing pre-clinical dental students' prosthodontic technical skills. (United States)

    Gratton, D G; Kwon, S R; Blanchette, D R; Aquilino, S A


    Proper integration of newly emerging digital assessment tools is a central issue in dental education in an effort to provide more accurate and objective feedback to students. The study examined how the outcomes of students' tooth preparation were correlated when evaluated using traditional faculty assessment and two types of digital assessment approaches. Specifically, incorporation of the Romexis Compare 2.0 (Compare) and Sirona prepCheck 1.1 (prepCheck) systems was evaluated. Additionally, satisfaction of students based on the type of software was evaluated through a survey. Students in a second-year pre-clinical prosthodontics course were allocated to either Compare (n = 42) or prepCheck (n = 37) systems. All students received conventional instruction and used their assigned digital system as an additional evaluation tool to aid in assessing their work. Examinations assessed crown preparations of the maxillary right central incisor (#8) and the mandibular left first molar (#19). All submissions were graded by faculty, Compare and prepCheck. Technical scores did not differ between student groups for any of the assessment approaches. Compare and prepCheck had modest, statistically significant correlations with faculty scores with a minimum correlation of 0.3944 (P = 0.0011) and strong, statistically significant correlations with each other with a minimum correlation of 0.8203 (P < 0.0001). A post-course student survey found that 55.26% of the students felt unfavourably about learning the digital evaluation protocols. A total of 62.31% felt favourably about the integration of these digital tools into the curriculum. Comparison of Compare and prepCheck showed no evidence of significant difference in students' prosthodontics technical performance and perception. © 2016 John Wiley & Sons A/S.

  19. Solar receiver with integrated optics (United States)

    Jiang, Lun; Winston, Roland


    The current challenge for PV/Thermal (PV/T) systems is the reduction of radiation heat loss. Compared to solar thermal selective coating, the solar cells cannot be used as an efficient thermal absorber due to their large emissivity of the encapsulation material. Many commercial PV/T products therefore require a high concentration (more than 10x) to reach an acceptable thermal efficiency for their receivers. Such a concentration system inevitably has to track or semi-track, which induces additional cost and collects only the direct radiation from the sun. We propose a new PV/T design using a vacuum encapsulated thin film cell to solve this problem. The proposed design also collects the diffuse sun light efficiently by using an external compound parabolic concentrator (XCPC). Since the transparent electrode (TCO) of thin film cell is inherently transparent in visible light and reflective beyond infrared, this design uses this layer instead of the conventional solar cell encapsulation as the outmost heat loss surface. By integrating such a vacuum design with a tube shaped absorber, we reduce the complexity of conducting the heat energy and electricity out of the device. A low concentration standalone non-tracking solar collector is proposed in this paper. We also analyzed the thermosyphon system configuration using heat transfer and ray tracing models. The economics of such a receiver are presented.

  20. Stress Response of Veterinary Students to Gynaecological Examination of Horse Mares - Effects of Simulator-Based and Animal-Based Training. (United States)

    Nagel, C; Ille, N; Erber, R; Aurich, C; Aurich, J


    Invasive procedures in animals are challenging for veterinary students who may perceive a gynaecological examination of mares as stressful. Simulator-based training may reduce stress. In this study, students received equine gynaecology training 4 times either on horses (group H; n = 14) or a teaching simulator (group SIM; n = 13). One day and 14 days thereafter, their diagnostic skills were tested on horses (skills tests 1 and 2). During the skills tests, the students' stress response was analysed by heart rate, heart rate variability (HRV) parameters SDRR (standard deviation of beat-to-beat [RR] interval) and RMSSD (root-mean-square of successive RR differences), and salivary cortisol. In addition, students answered a questionnaire on their perceived stress. Sympathetic activation with increased heart rate (p stress response. Subjective stress perception of students was higher in skills test 1 vs 2 (p stressed than SIM students (p stress parameters. In conclusion, gynaecological examination of mares evoked a moderate stress response in veterinary students, which was more evident after simulator-based than animal-based training. © 2015 Blackwell Verlag GmbH.

  2. Relative position control design of receiver UAV in flying-boom aerial refueling phase. (United States)

    An, Shuai; Yuan, Suozhong


    This paper proposes the design of the relative position-keeping control of the receiver unmanned aerial vehicle (UAV) with the time-varying mass in the refueling phase utilizing an inner-outer loop structure. Firstly, the model of the receiver in the refueling phase is established. And then tank model is set up to analyze the influence of fuel transfer on the receiver. Subsequently, double power reaching law based sliding mode controller is designed to control receiver translational motion relative to tanker aircraft in the outer loop while active disturbance rejection control technique is applied to the inner loop to stabilize the receiver. In addition, the closed-loop stabilities of the subsystems are established, respectively. Finally, an aerial refueling model under various refueling strategies is utilized. Simulations and comparative analysis demonstrate the effectiveness and robustness of the proposed controllers. Copyright © 2017 ISA. Published by Elsevier Ltd. All rights reserved.

  4. Testing foreign language impact on engineering students' scientific problem-solving performance (United States)

    Tatzl, Dietmar; Messnarz, Bernd


    This article investigates the influence of English as the examination language on the solution of physics and science problems by non-native speakers in tertiary engineering education. For that purpose, a statistically significant total number of 96 students in four year groups from freshman to senior level participated in a testing experiment in the Degree Programme of Aviation at the FH JOANNEUM University of Applied Sciences, Graz, Austria. Half of each test group were given a set of 12 physics problems described in German, the other half received the same set of problems described in English. It was the goal to test linguistic reading comprehension necessary for scientific problem solving instead of physics knowledge as such. The results imply that written undergraduate English-medium engineering tests and examinations may not require additional examination time or language-specific aids for students who have reached university-entrance proficiency in English as a foreign language.

  5. School lunch waste among middle school students: nutrients consumed and costs. (United States)

    Cohen, Juliana F W; Richardson, Scott; Austin, S Bryn; Economos, Christina D; Rimm, Eric B


    The National School Lunch Program has been guided by modest nutrient standards, and the palatability of meals, which drives consumption, receives inadequate attention. School food waste can have important nutritional and cost implications for policymakers, students, and their families. Nutrient losses and economic costs associated with school meal waste were examined. The study also assessed if school foods served were valid proxies for foods consumed by students. Plate waste measurements were collected from middle school students in Boston attending two Chef Initiative schools (n=1609) and two control schools (n=1440) during a 2-year pilot study (2007-2009) in which a professional chef trained cafeteria staff to make healthier school meals. The costs associated with food waste were calculated and the percentage of foods consumed was compared with a gold standard of 85% consumption. Analyses were conducted in 2010-2011. Overall, students consumed less than the required/recommended levels of nutrients. An estimated $432,349 of food (26.1% of the total food budget) was discarded by middle school students annually at lunch in these Boston middle schools. For most meal components, substantially less than 85% was consumed. There is substantial food waste among middle school students in Boston. Overall, students' nutrient consumption levels were below school meal standards, and foods served were not valid proxies for foods consumed. The costs associated with discarded foods are high; if translated nationally for school lunches, roughly $1,238,846,400 annually is wasted. Students might benefit if additional focus were given to the quality and palatability of school meals. Copyright © 2013 American Journal of Preventive Medicine. Published by Elsevier Inc.

  6. Assessment of Scientific Reasoning: the Effects of Task Context, Data, and Design on Student Reasoning in Control of Variables. (United States)

    Zhou, Shaona; Han, Jing; Koenig, Kathleen; Raplinger, Amy; Pi, Yuan; Li, Dan; Xiao, Hua; Fu, Zhao; Bao, Lei


    Scientific reasoning is an important component under the cognitive strand of the 21st century skills and is highly emphasized in the new science education standards. This study focuses on the assessment of student reasoning in control of variables (COV), which is a core sub-skill of scientific reasoning. The main research question is to investigate the extent to which the existence of experimental data in questions impacts student reasoning and performance. This study also explores the effects of task contexts on student reasoning as well as students' abilities to distinguish between testability and causal influences of variables in COV experiments. Data were collected with students from both USA and China. Students received randomly one of two test versions, one with experimental data and one without. The results show that students from both populations (1) perform better when experimental data are not provided, (2) perform better in physics contexts than in real-life contexts, and (3) students have a tendency to equate non-influential variables to non-testable variables. In addition, based on the analysis of both quantitative and qualitative data, a possible progression of developmental levels of student reasoning in control of variables is proposed, which can be used to inform future development of assessment and instruction.

  10. Do Women With Breast Cancer Who Choose Adjunctive Integrative Oncology Care Receive Different Standard Oncologic Treatment? (United States)

    Standish, Leanna J; Dowd, Fred; Sweet, Erin; Dale, Linda; Andersen, M Robyn


    To determine if women with breast cancer who choose adjunctive naturopathic oncology (NO) specialty care receive different standard oncologic treatment when compared with breast cancer patients who receive only standard care. Women with breast cancer stages 0 to 4, aged 18+ who spoke English and sought care from outpatient naturopathic doctor clinics were enrolled in an observational study of clinical and quality of life outcomes. Women who sought NO care 2 or more times within the first 2 years postdiagnosis were identified as NO cases. A matched comparison group of breast cancer patients were identified using the Western Washington Cancer Surveillance System(CSS). A longitudinal cohort design. In addition to self-report data, the CSS provided data on demographics, stage at the time of diagnosis, and initial treatment. Oncology medical records were abstracted in order to provide additional information on standard oncologic treatment for all participants. Cohorts were well matched with regard to demographic, histologic, and prognostic indicators at the time of diagnosis. Approximately 70% of women in both cohorts received standard oncologic care that met the National Comprehensive Cancer Network guidelines. There were no statistically significant differences between the cohorts in treatment received. Fewer women in the NO cohort with estrogen receptor-positive breast cancer appear to have received antiestrogen therapy. Women in both cohorts appear to receive guideline-concordant care. However, women who receive adjunctive NO care may be less likely to receive antiestrogen therapy.

  11. ASTRID© - Advanced Solar Tubular ReceIver Design: A powerful tool for receiver design and optimization (United States)

    Frantz, Cathy; Fritsch, Andreas; Uhlig, Ralf


    In solar tower power plants the receiver is one of the critical components. It converts the solar radiation into heat and must withstand high heat flux densities and high daily or even hourly gradients (due to passage of clouds). For this reason, the challenge during receiver design is to find a reasonable compromise between receiver efficiency, reliability, lifetime and cost. There is a strong interaction between the heliostat field, the receiver and the heat transfer fluid. Therefore, a proper receiver design needs to consider these components within the receiver optimization. There are several design and optimization tools for receivers, but most of them focus only on the receiver, ignoring the heliostat field and other parts of the plant. During the last years DLR developed the ASTRIDcode for tubular receiver concept simulation. The code comprises both a high and a low-detail model. The low-detail model utilizes a number of simplifications which allow the user to screen a high number of receiver concepts for optimization purposes. The high-detail model uses a FE model and is able to compute local absorber and salt temperatures with high accuracy. One key strength of the ASTRIDcode is its interface to a ray tracing software which simulates a realistic heat flux distributions on the receiver surface. The results generated by the ASTRIDcode have been validated by CFD simulations and measurement data.

  12. Development and Evaluation of vetPAL, a Student-Led, Peer-Assisted Learning Program. (United States)

    Bates, Lucy S W; Warman, Sheena; Pither, Zoe; Baillie, Sarah

    Based on an idea from a final-year student, Bristol Veterinary School introduced vetPAL, a student-led, peer-assisted learning program. The program involved fifth-year (final-year) students acting as tutors and leading sessions for fourth-year students (tutees) in clinical skills and revision (review) topics. The initiative aimed to supplement student learning while also providing tutors with opportunities to further develop a range of skills. All tutors received training and the program was evaluated using questionnaires collected from tutees and tutors after each session. Tutees' self-rated confidence increased significantly in clinical skills and for revision topics. Advantages of being taught by students rather than staff included the informal atmosphere, the tutees' willingness to ask questions, and the relatability of the tutors. The small group size and the style of learning in the revision sessions (i.e., group work, discussions, and interactivity) were additional positive aspects identified by both tutees and tutors. Benefits for tutors included developing their communication and teaching skills. The training sessions were considered key in helping tutors feel prepared to lead sessions, although the most difficult aspects were the lack of teaching experience and time management. Following the successful pilot of vetPAL, plans are in place to make the program permanent and sustainable, while incorporating necessary changes based on the evaluation and the student leader's experiences running the program. A vetPAL handbook has been created to facilitate organization of the program for future years.

    Samira Vesali


    Full Text Available Background Among the young generation, medical and law students’ attitude towards third party reproduction is very important because they will be directly involved in restricting or developing the programs that will support it in the future. The aim of this survey was to investigate attitude of law and medical students to oocyte donation and key aspects of this kind of third party. Materials and Methods In analytical cross-sectional study, 345 medical and law students were randomly selected using stratified sampling. Data was collected using attitude toward donation- oocyte (ATOD-O questionnaire. Re- sponses were on a 5-point Likert scale. Data were analyzed according to established statistical approach by Heeren and D'Agostino. Results The majority of the participants agreed with oocyte donation being the last choice for infertility treatment. There was a significant difference between medical students and law students regarding the acceptance of oocyte donation (3.23 vs. 3.53, P=0.025. In addition, female participants were more tolerant on receiving donated oocytes from their sisters than male participants (3.01 vs. 2.58, P=0.002 and finally, a higher number of the participants had a positive attitude towards anonymity of the donor and the recipient to one another (3.93 vs. 3.86, P=0.580. The vast majority of female students believed that the oocyte recipient naturally likes that child (P<0.0001. Conclusion In the current study, a great majority of law and medical students support oocyte donation as an alternative way of starting a family. There is an interest among female students in donating oocytes anonymously. The majority believed that the oocyte recipient family will like the donor oocyte child naturally.

  16. Software for Adapting Dspz Receivers to the Uran Interferometer Network (United States)

    Isaeva, E. A.; Lytvynenko, O. A.; Shepelev, V. A.

    More than 10 years ago, URAN interferometer network (Megn A.V.,1997; Konovalenko A.A., 2014) had been equipped with newly designed receivers with a pass band extended up to 250 kHz and software rejection of interferences (Rashkovskii, 2012). The broadening of bandwidth of received signal increase the sensitivity of the receivers significantly and let us to investigate the angular structure about one hundred radio sources. A software package had been developed that allows: preparing a program of observations, carrying out observations automatically, making data cross-correlation, calculating visibility functions for all pairs of antennae, and fitting models of an angular structure of the sources. Data storage formats were elaborated for each stage of recording or processing. At present, new digital radio astronomy receiver DSPZ have been developed by IRA NASU (Zakharenko, 2016). The receiver allows recording an entire bandwidth of signals of a decameter range from 8 to 32 MHz. It is used at UTR-2 and URAN radio telescopes operated in a single dish mode. Application of the receivers for interferometer observation with the URAN network provides additional advantages in accuracy and sensitivity of studies. In this report we consider the data formats and synchronization methods used in URAN equipment and DSPZ receivers, and discuss algorithms of their transformation. Newly elaborated software is described, that allows selecting a set of frequency bands of signals recorded with DSPZ and converting them to the form used by the URAN software. This approach allows us to carry out the interferometer observations in an the extended frequency range provided by DSPZ and to use as much as possible the software package developed for the URAN network for data reduction.

  17. Using the Learning Together Strategy to Affect Student Achievement in Physical Science (United States)

    Campbell, Manda D.

    Despite efforts mandated by national legislation, the state of Georgia has made little progress in improving Grade 5 students' standardized test scores in science, spurring the need for social change. The purpose of this quantitative causal-comparative study was to determine whether there was a significant difference in the student achievement in the conceptual understanding of science concepts in a classroom where the teacher applied the cooperative learning strategy, Learning Together, as compared to the classroom in which teacher-directed instruction was applied. The theories of positive social interdependence and social development, which posit that social interaction promotes cognitive gains, provided a framework for the study. A convenience sample of 38 students in Grade 5 participated in the 6-week study. Nineteen students received the cooperative learning strategy treatment, while 19 students did not. Pre- and post-tests were administered to students in both groups, and an analysis of variance was performed to examine differences between the 2 sample means. Results indicated that the group receiving the cooperative learning strategy scored significantly higher than did the control group receiving direct instruction. The experimental group also scored higher in vocabulary acquisition. Using the cooperative learning strategy of Learning Together could guide teachers' efforts to help students achieve excellent state-mandated test scores. Learning Together may be employed as a powerful teaching tool across grade levels and content areas, thus promoting positive gains in other state-mandated testing areas such as math, language arts, and social studies.

  18. Receiver-Assisted Congestion Control to Achieve High Throughput in Lossy Wireless Networks (United States)

    Shi, Kai; Shu, Yantai; Yang, Oliver; Luo, Jiarong


    Many applications would require fast data transfer in high-speed wireless networks nowadays. However, due to its conservative congestion control algorithm, Transmission Control Protocol (TCP) cannot effectively utilize the network capacity in lossy wireless networks. In this paper, we propose a receiver-assisted congestion control mechanism (RACC) in which the sender performs loss-based control, while the receiver is performing delay-based control. The receiver measures the network bandwidth based on the packet interarrival interval and uses it to compute a congestion window size deemed appropriate for the sender. After receiving the advertised value feedback from the receiver, the sender then uses the additive increase and multiplicative decrease (AIMD) mechanism to compute the correct congestion window size to be used. By integrating the loss-based and the delay-based congestion controls, our mechanism can mitigate the effect of wireless losses, alleviate the timeout effect, and therefore make better use of network bandwidth. Simulation and experiment results in various scenarios show that our mechanism can outperform conventional TCP in high-speed and lossy wireless environments.

  19. Cinemeducation: A pilot student project using movies to help students learn medical professionalism. (United States)

    Lumlertgul, Nuttha; Kijpaisalratana, Naruchorn; Pityaratstian, Nuttorn; Wangsaturaka, Danai


    Using movies has been accepted worldwide as a tool to help students learn medical professionalism. In the second year, a group of medical students conducted the "Cinemeducation" project to promote professionalism in the "Medical Ethics and Critical Thinking" course. Five movies with professionalism issues were screened with 20-30 students attending each session. After the show, participants then were asked to reflect on what they had learned in terms of professionalism. Two students led group discussion emphasizing questioning and argumentation for 60 min. Additional learning issues emerging from each session were also explored in more depth and arranged into a report. In the Cinemeducation Project, medical students have learned five main ethical issues in each film, which were the doctor-patient relationship, informed consent and clinical trials in patients, management of genetic disorders, patient management, and brain death and organ transplantation. In addition to issues of professionalism, they also developed critical thinking and moral reasoning skills. Using a case-based scenario in movies has proven to be an effective and entertaining method of facilitating students with learning on professionalism.

    Directory of Open Access Journals (Sweden)

    Nathan R. Jones


    Full Text Available The Nursing Global Health Professions Student Survey (GHPSS has been conducted in schools in 39 countries and the Gaza Strip/West Bank (identified as “sites” for the remainder of this paper. In half the sites, over 20% of the students currently smoked cigarettes, with males having higher rates than females in 22 sites. Over 60% of students reported having been exposed to secondhand smoke in public places in 23 of 39 sites. The majority of students recognized that they are role models in society, believed they should receive training on counseling patients to quit using tobacco, but few reported receiving any formal training. Tobacco control efforts must discourage tobacco use among health professionals, promote smoke free workplaces, and implement programs that train health professionals in effective cessation-counseling techniques.

    Cansever, Zeliha; Avsar, Zeynep; Cayir, Yasemin; Acemoglu, Hamit


    To document peer teaching activity performed by first-year medical students and their views on the teaching activity. Survey. Medical Education Department, Ataturk University, Erzurum, Turkey, in the 2012 - 2013 academic year. Volunteer students were selected for peer teaching model by an academician from the Medical Education Department. Students were taught subjects selected from classes such as biochemistry and microbiology in the same way as the academicians do. Following each class activity, the teaching student was assessed by the other students on a 5-point rating scale. Written and verbal feedback was also obtained from both teaching students and participated students. Verbal feedbacks were noted by a faculty member and similar opinions were categorized. Data were analyzed by SPSS version 20 statistical program. Eleven students took part in the program. Feedback was received from students 171 times. The mean number of students participated was 24.4 ± 14.3 in each program. Statistical analysis revealed that mean value for teaching materials, peer instructors and teaching environment were 4.62 ± 0.49, 4.63 ± 0.47 and 3.88 ± 1. 27 respectively. Peer teaching method is a pretty good way of teaching for medical students. It is a practicable technique that can be used in medical training. Taking part in this program as a lecturer, student increased students' self-confidence in the learning and teaching activities. Quite positive feedbacks were received.

  12. Solar advanced internal film receiver

    International Nuclear Information System (INIS)

    Torre Cabezas, M. de la


    In a Solar Central Internal Film Receiver, the heat absorbing fluid (a molten nitrate salt) flows in a thin film down over the non illuminated side of an absorber panel. Since the molten salt working fluid is not contained in complicated tube manifolds, the receiver design is simples than a conventional tube type-receiver resulting in a lower cost and a more reliable receiver. The Internal Film Receiver can be considered as an alternative to the Direct Absorption Receiver, in the event that the current problems of the last one can not be solved. It also describes here the test facility which will be used for its solar test, and the test plans foreseen. (Author) 17 refs

  13. Customizable Digital Receivers for Radar (United States)

    Moller, Delwyn; Heavey, Brandon; Sadowy, Gregory


    Compact, highly customizable digital receivers are being developed for the system described in 'Radar Interferometer for Topographic Mapping of Glaciers and Ice Sheets' (NPO-43962), NASA Tech Briefs, Vol. 31, No. 7 (August 2007), page 72. The receivers are required to operate in unison, sampling radar returns received by the antenna elements in a digital beam-forming (DBF) mode. The design of these receivers could also be adapted to commercial radar systems. At the time of reporting the information for this article, there were no commercially available digital receivers capable of satisfying all of the operational requirements and compact enough to be mounted directly on the antenna elements. A provided figure depicts the overall system of which the digital receivers are parts. Each digital receiver includes an analog-to-digital converter (ADC), a demultiplexer (DMUX), and a field-programmable gate array (FPGA). The ADC effects 10-bit band-pass sampling of input signals having frequencies up to 3.5 GHz. The input samples are demultiplexed at a user-selectable rate of 1:2 or 1:4, then buffered in part of the FPGA that functions as a first-in/first-out (FIFO) memory. Another part of the FPGA serves as a controller for the ADC, DMUX, and FIFO memory and as an interface between (1) the rest of the receiver and (2) a front-panel data port (FPDP) bus, which is an industry-standard parallel data bus that has a high data-rate capability and multichannel configuration suitable for DBF. Still other parts of the FPGA in each receiver perform signal-processing functions. The digital receivers can be configured to operate in a stand-alone mode, or in a multichannel mode as needed for DBF. The customizability of the receiver makes it applicable to a broad range of system architectures. The capability for operation of receivers in either a stand-alone or a DBF mode enables the use of the receivers in an unprecedentedly wide variety of radar systems.

  14. Receiver Gain Modulation Circuit (United States)

    Jones, Hollis; Racette, Paul; Walker, David; Gu, Dazhen


    A receiver gain modulation circuit (RGMC) was developed that modulates the power gain of the output of a radiometer receiver with a test signal. As the radiometer receiver switches between calibration noise references, the test signal is mixed with the calibrated noise and thus produces an ensemble set of measurements from which ensemble statistical analysis can be used to extract statistical information about the test signal. The RGMC is an enabling technology of the ensemble detector. As a key component for achieving ensemble detection and analysis, the RGMC has broad aeronautical and space applications. The RGMC can be used to test and develop new calibration algorithms, for example, to detect gain anomalies, and/or correct for slow drifts that affect climate-quality measurements over an accelerated time scale. A generalized approach to analyzing radiometer system designs yields a mathematical treatment of noise reference measurements in calibration algorithms. By treating the measurements from the different noise references as ensemble samples of the receiver state, i.e. receiver gain, a quantitative description of the non-stationary properties of the underlying receiver fluctuations can be derived. Excellent agreement has been obtained between model calculations and radiometric measurements. The mathematical formulation is equivalent to modulating the gain of a stable receiver with an externally generated signal and is the basis for ensemble detection and analysis (EDA). The concept of generating ensemble data sets using an ensemble detector is similar to the ensemble data sets generated as part of ensemble empirical mode decomposition (EEMD) with exception of a key distinguishing factor. EEMD adds noise to the signal under study whereas EDA mixes the signal with calibrated noise. It is mixing with calibrated noise that permits the measurement of temporal-functional variability of uncertainty in the underlying process. The RGMC permits the evaluation of EDA by

  15. Student perceptions of a simulation-based flipped classroom for the surgery clerkship: A mixed-methods study. (United States)

    Liebert, Cara A; Mazer, Laura; Bereknyei Merrell, Sylvia; Lin, Dana T; Lau, James N


    The flipped classroom, a blended learning paradigm that uses pre-session online videos reinforced with interactive sessions, has been proposed as an alternative to traditional lectures. This article investigates medical students' perceptions of a simulation-based, flipped classroom for the surgery clerkship and suggests best practices for implementation in this setting. A prospective cohort of students (n = 89), who were enrolled in the surgery clerkship during a 1-year period, was taught via a simulation-based, flipped classroom approach. Students completed an anonymous, end-of-clerkship survey regarding their perceptions of the curriculum. Quantitative analysis of Likert responses and qualitative analysis of narrative responses were performed. Students' perceptions of the curriculum were positive, with 90% rating it excellent or outstanding. The majority reported the curriculum should be continued (95%) and applied to other clerkships (84%). The component received most favorably by the students was the simulation-based skill sessions. Students rated the effectiveness of the Khan Academy-style videos the highest compared with other video formats (P flipped classroom in the surgery clerkship were overwhelmingly positive. The flipped classroom approach can be applied successfully in a surgery clerkship setting and may offer additional benefits compared with traditional lecture-based curricula.

  16. Feedback on students' clinical reasoning skills during fieldwork education. (United States)

    de Beer, Marianne; Mårtensson, Lena


    Feedback on clinical reasoning skills during fieldwork education is regarded as vital in occupational therapy students' professional development. The nature of supervisors' feedback however, could be confirmative and/or corrective and corrective feedback could be with or without suggestions on how to improve. The aim of the study was to evaluate the impact of supervisors' feedback on final-year occupational therapy students' clinical reasoning skills through comparing the nature of feedback with the students' subsequent clinical reasoning ability. A mixed-method approach with a convergent parallel design was used combining the collection and analysis of qualitative and quantitative data. From focus groups and interviews with students, data were collected and analysed qualitatively to determine how the students experienced the feedback they received from their supervisors. By quantitatively comparing the final practical exam grades with the nature of the feedback, their fieldwork End-of-Term grades and average academic performance it became possible to merge the results for comparison and interpretation. Students' clinical reasoning skills seem to be improved through corrective feedback if accompanied by suggestions on how to improve, irrespective of their average academic performance. Supervisors were inclined to underrate high performing students and overrate lower performing students. Students who obtained higher grades in the final practical examinations received more corrective feedback with suggestions on how to improve from their supervisors. Confirmative feedback alone may not be sufficient for improving the clinical reasoning skills of students. © 2015 The Authors.

    Cahan, Mitchell A; Larkin, Anne C; Starr, Susan; Wellman, Scott; Haley, Heather-Lyn; Sullivan, Kate; Shah, Shimul; Hirsh, Michael; Litwin, Demetrius; Quirk, Mark


    Early introduction of a full-day human factors training experience into the surgical clerkship curriculum will teach effective communication skills and strategies to gain professional satisfaction from a career in surgery. In pilot 1, which took place between July 1, 2007, and December 31, 2008, 50 students received training and 50 did not; all received testing at the end of the rotation for comparison of control vs intervention group performance. In pilot 2, a total of 50 students were trained and received testing before and after rotation to examine individual change over time. University of Massachusetts Medical School. A total of 148 third-year medical students in required 12-week surgical clerkship rotations. Full-day training with lecture and small-group exercises, cotaught by surgeons and educators, with focus on empathetic communication, time management, and teamwork skills. Empathetic communication skill, teamwork, and patient safety attitudes and self-reported use of time management strategies. Empathy scores were not higher for trained vs untrained groups in pilot 1 but improved from 2.32 to 3.45 on a 5-point scale (P work-life balance, with some trained groups scoring significantly lower than untrained groups in pilot 1 and no significant improvement shown in pilot 2. The significant increase in student-patient communication scores suggests that a brief focused presentation followed by simulation of difficult patient encounters can be successful. A video demonstration can improve interdisciplinary teamwork.

  18. Access to Waterless Hand Sanitizer Improves Student Hand Hygiene Behavior in Primary Schools in Nairobi, Kenya (United States)

    Pickering, Amy J.; Davis, Jennifer; Blum, Annalise G.; Scalmanini, Jenna; Oyier, Beryl; Okoth, George; Breiman, Robert F.; Ram, Pavani K.


    Handwashing is difficult in settings with limited resources and water access. In primary schools within urban Kibera, Kenya, we investigated the impact of providing waterless hand sanitizer on student hand hygiene behavior. Two schools received a waterless hand sanitizer intervention, two schools received a handwashing with soap intervention, and two schools received no intervention. Hand cleaning behavior after toilet use was monitored for 2 months using structured observation. Hand cleaning after toileting was 82% at sanitizer schools (N = 2,507 toileting events), 38% at soap schools (N = 3,429), and 37% at control schools (N = 2,797). Students at sanitizer schools were 23% less likely to have observed rhinorrhea than control students (P = 0.02); reductions in student-reported gastrointestinal and respiratory illness symptoms were not statistically significant. Providing waterless hand sanitizer markedly increased student hand cleaning after toilet use, whereas the soap intervention did not. Waterless hand sanitizer may be a promising option to improve student hand cleansing behavior, particularly in schools with limited water access. PMID:23836575

  19. Facilitating access to prenatal care through an interprofessional student-run free clinic. (United States)

    Danhausen, Kathleen; Joshi, Deepa; Quirk, Sarah; Miller, Robert; Fowler, Michael; Schorn, Mavis N


    Addressing the persistent challenge of inadequate prenatal care requires innovative solutions. Student-run free health centers are poised to rise to this challenge. The Shade Tree Clinic Early Pregnancy Program, jointly operated by university medical and nursing programs, functions as an ongoing access-to-care portal for pregnant women without health insurance. The clinic is run by medical students and nurse-midwifery students and uses a service-based learning model that allows students to work and learn in supervised, interprofessional teams while providing evidence-based prenatal care. All data reported in this paper were obtained from a retrospective chart review of women served by the prenatal clinic. These data are descriptive in nature, and include the patient demographics and services provided by the clinic to 152 women between the years of 2010-2013. During this time period, the clinic served a demographically diverse clientele. Approximately half lacked documentation of legal immigration status. The majority of women seeking care were in their first trimester of pregnancy and had previously given birth. Several women had medical or obstetric complications that required timely referral to specialist care; and many women received treatment for infection and other primary care concerns. Shade Tree Clinic provides the basic components of prenatal care and assists women with other medical needs. Women also receive help when applying for and accessing public maternity insurance, and the clinic facilitates entry to any necessary specialist care while that insurance is processed. In many cases, necessary and time-sensitive care would be delayed if Shade Tree Clinic's prenatal services were not available. In addition, the clinic presents a valuable opportunity for interprofessional socialization, increased respect, and improved collaboration between students in different but complementary professions, which is an important experience while we move to meet national

  20. A comprehensive survey of current and former college students with autism spectrum disorders. (United States)

    Gelbar, Nicholas W; Shefyck, Allison; Reichow, Brian


    There is a paucity of research concerning individuals with autism spectrum disorders (ASD) pursuing higher education. This study sought to augment this gap in the literature by surveying individuals with ASD who are currently college students or who have previously attended college. Thirty-five individuals completed an online survey. These individuals reported receiving extensive academic supports that enabled their academic success. Their reported difficulties in the social and emotional domains received less support. In addition, not all areas of campus life were supportive, as study abroad and career service offices were reported to not understand individuals with ASD. Overall, the results of this survey indicate the importance of self-advocacy and the need for institutions of higher education to provide comprehensive supports for individuals with ASD in the academic, social, and emotional domains in order to effectively integrate this group into the campus environment.

    Yoo, Moon Sook; Yoo, Il Young; Lee, Hyejung


    An opportunity for a student to evaluate his or her own performance enhances self-awareness and promotes self-directed learning. Using three outcome measures of competency of procedure, communication skills, and learning motivation, the effects of self-evaluation using a video recording of the student's Foley catheterization was investigated in this study. The students in the experimental group (n = 20) evaluated their Foley catheterization performance by reviewing the video recordings of their own performance, whereas students in the control group (n = 20) received written evaluation guidelines only. The results showed that the students in the experimental group had better scores on competency (p communication skills (p performance developed by reviewing a videotape appears to increase the competency of clinical skills in nursing students.

  3. Incorporating E-learning in teaching English language to medical students: exploring its potential contributions. (United States)

    Navidinia, Hossein; Zare Bidaki, Majid; Hekmati, Nargess


    Background: The spread of technology has influenced different aspects of human life, and teaching and learning are not exceptions. This study aimed to examine the potential contribution of the use of technology in teaching English language to medical students. Methods: This qualitative-action research study was conducted in Birjand University of Medical Sciences (BUMS), with 60 medical students taking a general English course in the Fall Semester of 2015. The class favored different tools and multimedia facilities such as a tube channel, e-dictionaries, educational films, and etextbooks to enhance students' learning. In addition, the class had a weblog in which students could upload assignments and receive feedback from peers and the instructors. Results: The results revealed that e-learning could enhance students' language proficiency and facilitate the teaching process. Learners preferred to use more e-dictionaries to learn the meaning of the new words, watch English medical films to boost their speaking and listening skills, and use the electronic version of their textbook as they could carry it wherever they wanted. Conclusion: The students preferred this method of learning English as they became more independent by using the electronic facilities. They found that learning English did not have a fixed institutionalized method, and e-learning activities could provide them with authentic input for language learning even outside of the classroom.

  4. An innovative addition to team-based-learning pedagogy to enhance teaching and learning: Students' perceptions of team exams. (United States)

    Khansari, Parto S; Coyne, Leanne

    The study investigates students' perceptions of the value of implementing a team exam to enhance learning prior to a summative assessment. Team exams are similar to midterm exams, except that answering questions is a team effort. Data was collected from second year pharmacy students at California Northstate University College of Pharmacy (CNUCOP) through a self-administered online survey. The survey questions included closed-ended questions to evaluate students' perception on preparedness for a summative assessment and to rank advantages and disadvantages of the team exams. Of the 40 students who completed the survey (38% response rate), 100% of participants agreed that having a team exam prior to a major exam made them feel more prepared for a major summative exam. Ninety-seven percent of students believed that the team exam helped them to identify gaps in their knowledge and 85% agreed that taking a team exam reinforced their knowledge by teaching other students. The survey results did not identify any major disadvantages to holding a team exam. Students perceived that taking a team exam prior to a midterm exam is an effective approach to review the course contents and identify areas of improvement. Copyright © 2017.

  6. Using Technology to Enhance Teaching of Patient-Centered Interviewing for Early Medical Students. (United States)

    Kaltman, Stacey; Talisman, Nicholas; Pennestri, Susan; Syverson, Eleri; Arthur, Paige; Vovides, Yianna


    Effective strategies for teaching communication skills to health professions students are needed. This article describes the design and evaluation of immersive and interactive video simulations for medical students to practice basic communication skills. Three simulations were developed, focusing on patient-centered interviewing techniques such as using open-ended questions, reflections, and empathic responses while assessing a patient's history of present illness. First-year medical students were randomized to simulation or education-as-usual arms. Students in the simulation arm were given access to three interactive video simulations developed using Articulate Storyline, an e-learning authoring tool, to practice and receive feedback on patient-centered interviewing techniques to prepare for their Observed Structured Clinical Examination (OSCE). Trained raters evaluated videos of two OSCE cases for each participant to assess specific communication skills used during the history of present illness component of the interview. Eighty-seven percent of the students in the simulation arm interacted with at least one simulation during the history of present illness. For both OSCE cases, students in the simulation arm asked significantly more open-ended questions. Students in the simulation arm asked significantly fewer closed-ended questions and offered significantly more empathic responses in one OSCE case. No differences were found for reflections. Students reported that the simulations helped improve their communication skills. The use of interactive video simulations was found to be feasible to incorporate into the curriculum and was appealing to students. In addition, students in the simulation arm displayed more behaviors consistent with the patient-centered interviewing model practiced in the simulations. Continued development and research are warranted.

  7. Client-centeredness of Finnish and Estonian nursing students and the support from nursing education to develop it. Students' self-evaluation. (United States)

    Kalam-Salminen, Ly; Valkonen, Marjo-Riitta; Aro, Ilme; Routasalo, Pirkko


    The purpose of this comparative study is to describe the differences between Finnish and Estonian students evaluations about their client-centeredness and educational support they received to develop it. Client-centeredness has many positive effects on the quality and effectiveness of care. However, some deficiencies have been identified in the client-centeredness of nursing staff. Research on the subject has been limited, and we lack knowledge of graduating students' competence in client-centeredness and the support of their education to develop it. The sample consisted of 390 undergraduate nursing students, 195 from Finland and 195 from Estonia. The data were collected in 2009 using the structured five-point scale questionnaire. The questionnaire was designed to measure students' client-centeredness and the educational support they received from nursing education. The data were analyzed by the PASW Statistics 18-programme using descriptive statistics, Kolmogorov-Smirnov test and Mann-Whitney U-test. Predominantly, students in both countries evaluated their level of client-centeredness high. The Estonian students generally evaluated their client-centeredness higher compared to the Finnish students. The same applied to support provided by nursing education. The greatest differences were related to education and particularly theoretical teaching. In Estonia, students' client-centeredness manifested itself more in politeness and willingness to serve clients, whereas respecting the clients' values was emphasized in Finland. Students' requisites, referred here as knowledge, skills and abilities to implement client-centered nursing, for client-centeredness had deficiencies, and the support from education was also the weakest regarding these aspects. In future, education on development of nursing activities, acquisition of knowledge and services provided by health care as well as legislation should be enhanced, since these areas proved the most difficult for the students

  9. Impact of educational messages on patient acceptance of male medical students in OB-GYN encounters. (United States)

    Buck, Katherine; Littleton, Heather


    Although training in obstetrics and gynecology is a key part of medical education, male students receive less extensive experience, due in part to patient refusals. However, there is limited work seeking to reduce patient refusal rates of male students. The current study examined the efficacy of two messages at increasing male medical student acceptance into a well-woman visit. A total of 656 college women participated in a simulation study where they viewed a video of a nurse asking for permission to have a male medical student participate in their well-woman visit. The 30.5% of women who refused student participation (n = 181) were randomly assigned to view a video of the nurse either describing students' medical knowledge and technical skills training (e.g. training in performing pelvic exams) or empathic skills training (e.g. training in communication about sensitive issues). They were again asked if they would be willing to have the student participate. Both messages similarly increased student acceptance with 44.8% of those receiving the empathic skills training message and 48.9% of those who received the medical/technical skills training message accepting student participation, χ(2) (1, N = 181) = 0.3, p = 0.58. Educational messages about medical student training delivered in an engaging fashion by a credible source are a potentially effective tool to increase male student acceptance into sensitive patient encounters. Future work should test these messages in real-world settings as part of a focus on patient education to increase comfort with student participation.

  10. Monitoring student attendance, participation, and performance improvement: an instrument and forms. (United States)

    Kosta, Joanne


    When students receive consistent and fair feedback about their behavior, program liability decreases. To help students to have a clearer understanding of minimum program standards and the consequences of substandard performance, the author developed attendance and participation monitoring and performance improvement instruments. The author discusses the tools that address absenteeism, tardiness, unprofessional, and unsafe clinical behaviors among students.

    activities. The program provides teachers with a one-week summer professional development workshop, long-term teacher support through classroom visits, teacher access to GLOBE instrumentation, and research opportunities for students. Professional development is centered on student engagement through inquiry, opportunities for collaborative student research, and the GLOBE Program's atmosphere protocols and learning activities. Beyond the training week, teachers receive follow-up specifically addressing current opportunities for student engagement in current research and opportunities for students to present research findings. The first cohort of teachers completed the professional development workshop in July 2012. This session will summarize the planning and implementation details of the summer workshop, including schedule and materials. In addition to these details, we will share our evaluation of follow-up activities and survey results highlighting teachers' perceived barriers to implementing atmosphere investigations. These results will add to the discussion on effective programs aimed at inspiring young scientists.

  13. Extending the Pathway: Building on a National Science Foundation Workforce Development Project for Underserved k-12 Students (United States)

    Slattery, W.; Smith, T.


    With new career openings in the geosciences expected and a large number of presently employed geoscientists retiring in the next decade there is a critical need for a new cadre of geoscientists to fill these positions. A project funded by the National Science Foundation titled K-12 Students, Teachers, Parents, Administrators and Higher Education Faculty: Partners Helping Rural Disadvantaged Students Stay on the Pathway to a Geoscience Career involving Wright State University and the Ripley, Lewis, Union, Huntington k-12 school district in Appalachian Ohio took led to dozens of seventh and eighth grade students traveling to Sandy Hook, New Jersey for a one week field experience to study oceanography with staff of the New Jersey Sea Grant Consortium. Teachers, parent chaperones, administrators and university faculty accompanied the students in the field. Teachers worked alongside their students in targeted professional development during the weeklong field experience. During the two academic years of the project, both middle school and high school teachers received professional development in Earth system science so that all students, not just those that were on the summer field experience could receive enhanced science learning. All ninth grade high school students were given the opportunity to take a high school/college dual credit Earth system science course. Community outreach provided widespread knowledge of the project and interest among parents to have their children participate. In addition, ninth grade students raised money themselves to fund a trip to the International Field Studies Forfar Field Station on Andros Island, Bahamas to study a tropical aquatic system. Students who before this project had never traveled outside of Ohio are currently discussing ways that they can continue on the pathway to a geoscience career by applying for internships for the summer between their junior and senior years. These are positive steps towards taking charge of their

  15. Understanding the bullying dynamic among students in special and general education. (United States)

    Swearer, Susan M; Wang, Cixin; Maag, John W; Siebecker, Amanda B; Frerichs, Lynae J


    Students in general and special education experience bullying. However, few empirical investigations have examined involvement in bullying along the bully/victim continuum (i.e., as a bully, victim, or bully-victim) among students with disabilities. A total of 816 students, ages 9 to 16, participated in the present study. From this total sample 686 were not receiving special education services (categorized as "no disability"), and 130 were receiving special education services (categorized as "observable disability," "non-observable disability," and "behavioral disability"). Data on students' involvement in bullying, office referrals, and prosocial behavior were collected. Results indicated that students with behavioral disorders and those with observable disabilities reported bullying others more and being victimized more than their general education counterparts. Students with behavioral disorders also had significantly more office referrals than students in general education. Seventh graders in general education reported more bullying behavior than sixth graders and ninth grades in general education. Fifth graders in general education reported more victimization than students in all other grades in general education. However, the grade differences were not significant for students in special education. No gender differences on bullying and victimization were found. Students with disabilities reported less engagement in prosocial behaviors than their general education peers. Implications for bullying prevention and intervention across both general and special education are discussed. Copyright © 2012. Published by Elsevier Ltd.

  16. Development and Implementation of an Electronic Clinical Formative Assessment: Dental Faculty and Student Perspectives. (United States)

    Kirkup, Michele L; Adams, Brooke N; Meadows, Melinda L; Jackson, Richard


    A traditional summative grading structure, used at Indiana University School of Dentistry (IUSD) for more than 30 years, was identified by faculty as outdated for assessing students' clinical performance. In an effort to change the status quo, a feedback-driven assessment was implemented in 2012 to provide a constructive assessment tool acceptable to both faculty and students. Building on the successful non-graded clinical evaluation employed at Baylor College of Dentistry, IUSD implemented a streamlined electronic formative feedback model (FFM) to assess students' daily clinical performance. An important addition to this evaluation tool was the inclusion of routine student self-assessment opportunities. The aim of this study was to determine faculty and student response to the new assessment instrument. Following training sessions, anonymous satisfaction surveys were examined for the three user groups: clinical faculty (60% response rate), third-year (D3) students (72% response rate), and fourth-year (D4) students (57% response rate). In the results, 70% of the responding faculty members preferred the FFM over the summative model; however, 61.8% of the D4 respondents preferred the summative model, reporting insufficient assessment time and low faculty participation. The two groups of students had different responses to the self-assessment component: 70.2% of the D4 respondents appreciated clinical self-assessment compared to 46% of the D3 respondents. Overall, while some components of the FFM assessment were well received, a phased approach to implementation may have facilitated a transition more acceptable to both faculty and students. Improvements are being made in an attempt to increase overall satisfaction.

  17. Structured feedback on students' concept maps: the proverbial path to learning? (United States)

    Joseph, Conran; Conradsson, David; Nilsson Wikmar, Lena; Rowe, Michael


    Good conceptual knowledge is an essential requirement for health professions students, in that they are required to apply concepts learned in the classroom to a variety of different contexts. However, the use of traditional methods of assessment limits the educator's ability to correct students' conceptual knowledge prior to altering the educational context. Concept mapping (CM) is an educational tool for evaluating conceptual knowledge, but little is known about its use in facilitating the development of richer knowledge frameworks. In addition, structured feedback has the potential to develop good conceptual knowledge. The purpose of this study was to use Kinchin's criteria to assess the impact of structured feedback on the graphical complexity of CM's by observing the development of richer knowledge frameworks. Fifty-eight physiotherapy students created CM's targeting the integration of two knowledge domains within a case-based teaching paradigm. Each student received one round of structured feedback that addressed correction, reinforcement, forensic diagnosis, benchmarking, and longitudinal development on their CM's prior to the final submission. The concept maps were categorized according to Kinchin's criteria as either Spoke, Chain or Net representations, and then evaluated against defined traits of meaningful learning. The inter-rater reliability of categorizing CM's was good. Pre-feedback CM's were predominantly Chain structures (57%), with Net structures appearing least often. There was a significant reduction of the basic Spoke- structured CMs (P = 0.002) and a significant increase of Net-structured maps (P student development.

  18. "That's so gay!" Exploring college students' attitudes toward the LGBT population. (United States)

    Holland, Laurel; Matthews, Todd L; Schott, Melinda R


    Traditional students are often introduced to unfamiliar subcultures for the first time on the college campus. Recent high school graduates find themselves transitioning from an atmosphere in which homophobia is likely to be tolerated and possibly even expected to an educational setting in which diversity is promoted. Research shows that the college years are influential in the re-socialization of core values, yet very little work focuses on the ideological shifts that may take place in attitudes toward the lesbian, gay, bisexual, and transgendered (LGBT) population. The research presented in this study includes a modified version of LaMar and Kite's Component Measure, which has been broken down into 6 distinctive components of tolerance. In addition to examining religion, gender, and race--factors that have been correlated in past research with differing levels of tolerance toward the LGBT community--this study adds politics, sexual orientation, academic class standing, and college of major--variables that have received little or no attention in this literature. Higher levels of LGBT tolerance are consistently observed across the indexes among women, more liberal Christian traditions, non-Christian faiths, the non-religious, and those who self-identify as LGBT. The distinctive contribution of this study is that students in the College of Arts and Sciences and students further along in their college careers are also more tolerant. Based on these findings, recommendations are made for inter-college curriculum changes that integrate students in all disciplines and students of all classifications.

    manufacturing. The cost and design goals for the project were met with this task, but the most interesting results had to do with defining the failure modes and looking at a “shakedown analysis” of the combined creep-fatigue failure. A separate task also looked at improving the absorber coatings on the receiver tubes that would improve the efficiency of the receiver. Significant progress was made on developing a novel paint with a high absorptivity that was on par with the current Pyromark, but shows additional potential to be optimized further. Although the coating did not meet the emissivity goals, preliminary testing the new paint shows potential to be much more durable, and potential to improve the receiver efficiency through a higher average absorptivity over the lifetime. Additional coatings were also designed and modeled results meet the project goals, but were not tested. Testing for low cycle fatigue of the full length receiver tubes was designed and constructed, but is still currently undergoing testing. A novel small heliostat was developed through an extensive brainstorming and down select. The concept was then detailed further with inputs from component testing and eventually a full prototype was built and tested. This task met or exceeded the accuracy and structure goals and also beat the cost goal. This provides a significant solar field costs savings for Abengoa that will be developed further to be used in future commercial plants. Ultimately the $0.09/kWhe (real 2009 $) and 6,400 hours goals of the project were met.

    Cristina Vázquez


    Full Text Available Teachers’ beliefs about family-school relationship vary in a continuum according to the role that parents and teachers have, and the power that they hold. Pre-service teachers also have beliefs about this relationship and their own competence to develop it. Two groups of pre-service teachers (second year students participated in this study. One group received specific training on family-school relationship and its improvement (116 students attending a degree in Early Childhood Education, who constituted the experimental group, EG. The other group was not trained (92 students attending a degree in Primary Education, who made up the control group, CG. The Beliefs about family-school Questionnaire (CCR was developed and applied before and after the EG was trained. Results show that students in the EG increased their beliefs about family-school collaboration in the post-test and decreased their beliefs about parental subordination to teachers’ authority and parents’ carelessness. Students in the CG kept their beliefs unchanged, which were significantly more prone to support teachers’ authority and parental subordination and parents’ carelessness compared to the EG.. Perceived competence for family-school relationship did not change significantly in either group. However, significant correlations between beliefs and perceived competence were found, pointing out the importance of working pre-service teachers’ beliefs about family-school collaboration.

  8. Topics in Bioethics: A Development of Student Perspectives

    Directory of Open Access Journals (Sweden)

    Keith A. Johnson


    Full Text Available Exposing students to current biotechnological and medical issues is eye-opening for many students in a way that is not always achieved through lecture-based learning. Lecture or investigative teaching styles provide a tremendous knowledge base for the students, but sometimes these teaching styles do not allow the student to fully develop, especially personal attitudes to issues in bioethics. Through online videos, Hollywood movies, guided readings and classroom discussions, students in this course are informed of some bioethical topics, encouraged to learn about other topics, and use this gained knowledge to develop personal positions regarding the value and/or risk of the issues. This course has been well-received by previous students as a favorite in terms of both topics covered and style.

  12. Autonomy and the Student Experience in Introductory Physics (United States)

    Hall, Nicholas Ron

    The role of autonomy in the student experience in a large-enrollment undergraduate introductory physics course was studied from a Self-Determination Theory perspective with two studies. Study I, a correlational study, investigated whether certain aspects of the student experience correlated with how autonomy supportive (vs. controlling) students perceived their instructors to be. An autonomy supportive instructor acknowledges students' perspectives, feelings, and perceptions and provides students with information and opportunities for choice, while minimizing external pressures. It was found that the degree to which students perceived their instructors as autonomy supportive was positively correlated with student interest and enjoyment in learning physics (beta=0.31***) and negatively correlated with student anxiety about taking physics (beta=-0.23**). It was also positively correlated with how autonomous (vs. controlled) students' reasons for studying physics became over the duration of the course (i.e., studying physics more because they wanted to vs. had to; beta=0.24***). This change in autonomous reasons for studying physics was in turn positively correlated with student performance in the course (beta=0.17*). Additionally, the degree to which students perceived their instructors as autonomy supportive was directly correlated with performance for those students entering the course with relatively autonomous reasons for studying physics (beta=0.25**). In summary, students who perceived their instructors as more autonomy supportive tended to have a more favorable experience in the course. If greater autonomy support was in fact the cause of a more favorable student experience, as suggested by Self-determination Theory and experimental studies in other contexts, these results would have implications for instruction and instructor professional development in similar contexts. I discuss these implications. Study II, an experimental study, investigated the effect

  13. Intimate Partner Violence in South Chilean College Students

    Directory of Open Access Journals (Sweden)

    Maria Beatriz Vizcarra Larrañaga


    Full Text Available The present study sought to estimate the magnitude of intimate partner violence (IPV in university students in southern Chile; to describe its manifestations, its associated factors, consequences and coping strategies. Method: A descriptive quantitative design was used, the sample was constituted by 447 university students randomly selected balanced by sex. Participants were asked about violent behaviour conduct through a questionnaire. Results: 57% of those questioned reported having experienced some psychological abuse, 26% reported physical violence at least once in their lifetime. Associated factors to receive physical violence were: sex, suffering psychological violence, favourable attitudes towards violence, and low religious participation. Associated factor to receive psychological violence was: sex, physical violence received, favourable attitudes towards the violence, and the length of the relationship. Discussion: Typical features of intimate partner violence in college life settings seem to favor its invisibility, thus turning it into a difficult phenomenon to approach and to prevent.

    Full Text Available Mapping with Micro Aerial Vehicles (MAVs whose weight does not exceed 5 kg is gaining importance in applications such as corridor mapping, road and pipeline inspections, or mapping of large areas with homogeneous surface structure, e.g. forest or agricultural fields. In these challenging scenarios, integrated sensor orientation (ISO improves effectiveness and accuracy. Furthermore, in block geometry configurations, this mode of operation allows mapping without ground control points (GCPs. Accurate camera positions are traditionally determined by carrier-phase GNSS (Global Navigation Satellite System positioning. However, such mode of positioning has strong requirements on receiver’s and antenna’s performance. In this article, we present a mapping project in which we employ a single-frequency, low-cost (< $100 GNSS receiver on a MAV. The performance of the low-cost receiver is assessed by comparing its trajectory with a reference trajectory obtained by a survey-grade, multi-frequency GNSS receiver. In addition, the camera positions derived from these two trajectories are used as observations in bundle adjustment (BA projects and mapping accuracy is evaluated at check points (ChP. Several BA scenarios are considered with absolute and relative aerial position control. Additionally, the presented experiments show the possibility of BA to determine a camera-antenna spatial offset, so-called lever-arm.

    The channelized receiver being presented demonstrates the use of high temperature superconductor technology in a microwave system setting where superconductor, microwave-monolithic-integrated-circuit, and hybrid-integrated-circuit components are united in one package and cooled to liquid-nitrogen temperatures. The receiver consists of a superconducting X-band four-channel demultiplexer with 100-MHz-wide channels, four commercial monolithically integrated mixers, and four custom-designed hybrid-circuit detectors containing heterostructure ramp diodes. The composite receiver unit has been integrated into the payload of the second-phase NRL high temperature superconductor space experiment (HTSSE-II). Prior to payload assembly, the response characteristics of the receiver were measured as functions of frequency, temperature, and drive levels. The article describes the circuitry, discusses the key issues related to design and implementation, and summarizes the experimental results

  3. Using modern teaching strategies to teach upper abdominal sonography to medical students. (United States)

    Cheng, Wei-Chun; Lin, Xi-Zhang; Chen, Chiung-Yu


    Upper abdominal sonography can help physicians to confirm the diagnosis of various hepatobiliary diseases. Teaching sonography skills to medical students is important because it may enhance their level of knowledge and overall development during their gastroenterology section rotation. Sonographic imaging is abstract and students can be easily confused when scanning the abdominal structures from different sites and directions. We used several modern teaching strategies to facilitate the learning of sonography skills. The year five medical students beginning a gastroenterology section rotation for their first-year clerkship were taught abdominal sonography skills. Abstract sonographic images were related to concrete objects and the surrounding structures were further indicated. Each of the images was given a specific name and was sorted according to the scanning site. A mnemonics system was designed to help students to memorize the names of these images. A badge was created to recognize the achievement of being able to complete a basic upper abdominal sonography. Students were free (i.e., not obligated) to request a demonstration opportunity to show their skills within 2 weeks after receiving tutelage. We recorded the number of students who received training and were able to successfully complete the task; these individuals then received a badge to be pinned onto their white coats. Sixty-three of 68 students (92.6%) requested evaluation and all of them passed. We have greatly simplified the process of learning about upper abdominal sonography by using andragogy to enhance learning, mnemonics to help memory, and a pin-badge reward system to stimulate incentives.

  4. A randomized control study of psychological intervention to reduce anxiety, amotivation and psychological distress among medical students. (United States)

    Saravanan, Coumaravelou; Kingston, Rajiah


    Test anxiety aggravates psychological distress and reduces the motivation among graduate students. This study aimed to identify psychological intervention for test anxiety, which reduces the level of psychological distress, amotivation and increases the intrinsic and extrinsic motivation among medical students. Westside test anxiety scale, Kessler Perceived Stress Scale and Academic Motivation Scale were used to measure test anxiety, psychological distress and motivation on 436 1(st) year medical students. Out of 436 students, 74 students who exhibited moderate to high test anxiety were randomly divided into either experimental or waiting list group. In this true randomized experimental study, 32 participants from the intervention group received five sessions of psychological intervention consist of psychoeducation, relaxation therapy and systematic desensitization. Thirty-three students from waiting list received one session of advice and suggestions. After received psychological intervention participants from the intervention group experienced less anxiety, psychological distress, and amotivation (P < 0.01) and high intrinsic and extrinsic motivation (P < 0.01) in the postassessment compared with their preassessment scores. Overall psychological intervention is effective to reduce anxiety scores and its related variables.

  5. The effect of cognitive education on the performance of students with neurological developmental disabilities. (United States)

    Jepsen, Ruthanne H; VonThaden, Karen


    A cognitive education program was developed to facilitate acquisition of cognitive skills and address the learning deficits of adolescent students with neurological, developmental disabilities, and autism. This study examined the outcomes of incorporating mediated cognitive education into special education classrooms. Cognitive education provided cognitive training utilizing REHABIT materials through mediated teaching. Following a matched pair model, forty-six students were assigned to either a treatment or a control group. All students received weekly instruction in Individual Educational Program (IEP) goals. Curriculum areas included IEP objectives in reading, math, social skills, health, science and social studies. Students in the control group received regular classroom instruction. Students in the treatment group participated in cognitive educated one hour per week replacing thirty minutes of reading and thirty minutes of math. Pre and posttest comparisons on measures of intelligence, achievement and adaptive behavior showed those students in the treatment group attained higher scores across measures.

  6. The effect of student self-video of performance on clinical skill competency: a randomised controlled trial. (United States)

    Maloney, Stephen; Storr, Michael; Morgan, Prue; Ilic, Dragan


    Emerging technologies and student information technology literacy are enabling new methods of teaching and learning for clinical skill performance. Facilitating experiential practice and reflection on performance through student self-video, and exposure to peer benchmarks, may promote greater levels of skill competency. This study examines the impact of student self-video on the attainment of clinical skills. A total of 60 Physiotherapy students (100%) consented to participate in the randomised controlled trial. One group (50%) was taught a complex clinical skill with regular practical tutoring, whilst the other group (50%) supplemented the tutoring with a self-video task aimed at promoting reflection on performance. Student skill performance was measured in an objective structured clinical examination (OSCE). Students also completed an anonymous questionnaire, which explored their perception of their learning experiences. Students received significantly higher scores in the OSCE when the examined clinical skill had been supplemented with a self-video of performance task (P = 0.048). Descriptive analysis of the questionnaires relating to student perceptions on the teaching methods identified that the self-video of performance task utilised contributed to improvement in their clinical performance and their confidence for future clinical practice. Students identified a number of aspects of the submission process that contributed to this perception of educational value. The novel results of this study demonstrate that greater clinical skill competency is achieved when traditional tutoring methods are supplemented with student self-video of performance tasks. Additional benefits included the ability of staff and students to monitor longitudinal performance, and an increase in feedback opportunities.

    Very little Canadian research has examined the academic achievement of private school students. Data from The Programme for International Student Assessment (PISA) 2003 were used to examine the achievement of private school students. The study found that private school students outperformed their public school peers. In addition, the students'…

  9. Engaging Undergraduate Students in Space Weather Research at a 2- Year College (United States)

    Damas, M. C.


    The Queensborough Community College (QCC) of the City University of New York (CUNY), a Hispanic and minority-serving institution, has been very successful at engaging undergraduate students in space weather research for the past ten years. Recently, it received two awards to support student research and education in solar and atmospheric physics under the umbrella discipline of space weather. Through these awards, students receive stipends during the academic year and summer to engage in scientific research. Students also have the opportunity to complete a summer internship at NASA and at other partner institutions. Funding also supports the development of course materials and tools in space weather. Educational materials development and the challenges of engaging students in research as early as their first year will be discussed. Once funding is over, how is the program sustained? Sustaining such a program, as well as how to implement it at other universities will also be discussed.

  10. The Role of Humor in Learning Physics: A Study of Undergraduate Students (United States)

    Berge, Maria


    We all know that they do it, but what do students laugh "about" when learning science together? Although research has shown that students do use humor when they learn science, the role of humor in science education has received little attention. In this study, undergraduate students' laughter during collaborative work in physics has been…

  11. No detectable fertility benefit from a single additional mating in wild stalk-eyed flies.

    Directory of Open Access Journals (Sweden)

    Elisabeth Harley


    Full Text Available Multiple mating by female insects is widespread, and the explanation(s for repeated mating by females has been the subject of much discussion. Females may profit from mating multiply through direct material benefits that increase their own reproductive output, or indirect genetic benefits that increase offspring fitness. One particular direct benefit that has attracted significant attention is that of fertility assurance, as females often need to mate multiply to achieve high fertility. This hypothesis has never been tested in a wild insect population.Female Malaysian stalk-eyed flies (Teleopsis dalmanni mate repeatedly during their lifetime, and have been shown to be sperm limited under both laboratory and field conditions. Here we ask whether receiving an additional mating alleviates sperm limitation in wild females. In our experiment one group of females received a single additional mating, while a control group received an interrupted, and therefore unsuccessful, mating. Females that received an additional mating did not lay more fertilised eggs in total, nor did they lay proportionately more fertilised eggs. Female fertility declined significantly through time, demonstrating that females were sperm limited. However, receipt of an additional mating did not significantly alter the rate of this decline.Our data suggest that the fertility consequences of a single additional mating were small. We discuss this effect (or lack thereof, and suggest that it is likely to be attributed to small ejaculate size, a high proportion of failed copulations, and the presence of X-linked meiotic drive in this species.

  12. Effect of Computer-Assisted Learning on Students' Dental Anatomy Waxing Performance. (United States)

    Kwon, So Ran; Hernández, Marcela; Blanchette, Derek R; Lam, Matthew T; Gratton, David G; Aquilino, Steven A


    The aim of this study was to evaluate the impact of computer-assisted learning on first-year dental students' waxing abilities and self-evaluation skills. Additionally, this study sought to determine how well digital evaluation software performed compared to faculty grading with respect to students' technical scores on a practical competency examination. First-year students at one U.S. dental school were assigned to one of three groups: control (n=40), E4D Compare (n=20), and Sirona prepCheck (n=19). Students in the control group were taught by traditional teaching methodologies, and the technology-assisted groups received both traditional training and supplementary feedback from the corresponding digital system. Five outcomes were measured: visual assessment score, self-evaluation score, and digital assessment scores at 0.25 mm, 0.30 mm, and 0.35 mm tolerance. The scores from visual assessment and self-evaluation were examined for differences among groups using the Kruskal-Wallis test. Correlation between the visual assessment and digital scores was measured using Pearson and Spearman rank correlation coefficients. At completion of the course, students were asked to complete a survey on the use of these digital technologies. All 79 students in the first-year class participated in the study, for a 100% response rate. The results showed that the visual assessment and self-evaluation scores did not differ among groups (p>0.05). Overall correlations between visual and digital assessment scores were modest though statistically significant (5% level of significance). Analysis of survey responses completed by students in the technology groups showed that profiles for the two groups were similar and not favorable towards digital technology. The study concluded that technology-assisted training did not affect these students' waxing performance or self-evaluation skills and that visual scores given by faculty and digital assessment scores correlated moderately.

  13. Comparing the Effects of Objective Structured Assessment of Technical Skills (OSATS) and Traditional Method on Learning of Students. (United States)

    Mansoorian, Mohammad Reza; Hosseiny, Marzeih Sadat; Khosravan, Shahla; Alami, Ali; Alaviani, Mehri


    Despite the benefits of the objective structured assessment of technical skills (OSATS) and it appropriateness for evaluating clinical abilities of nursing students , few studies are available on the application of this method in nursing education. The purpose of this study was to compare the effect of using OSATS and traditional methods on the students' learning. We also aimed to signify students' views about these two methods and their views about the scores they received in these methods in a medical emergency course. A quasi-experimental study was performed on 45 first semester students in nursing and medical emergencies passing a course on fundamentals of practice. The students were selected by a census method and evaluated by both the OSATS and traditional methods. Data collection was performed using checklists prepared based on the 'text book of nursing procedures checklists' published by Iranian nursing organization and a questionnaire containing learning rate and students' estimation of their received scores. Descriptive statistics as well as paired t-test and independent samples t-test were used in data analysis. The mean of students' score in OSATS was significantly higher than their mean score in traditional method (P = 0.01). Moreover, the mean of self-evaluation score after the traditional method was relatively the same as the score the students received in the exam. However, the mean of self-evaluation score after the OSATS was relatively lower than the scores the students received in the OSATS exam. Most students believed that OSATS can evaluate a wide range of students' knowledge and skills compared to traditional method. Results of this study indicated the better effect of OSATS on learning and its relative superiority in precise assessment of clinical skills compared with the traditional evaluation method. Therefore, we recommend using this method in evaluation of students in practical courses.

  14. A Combined Time Domain Impedance Probe And Plasma Wave Receiver System For Small Satellite Applications. (United States)

    Spencer, E. A.; Clark, D. C.; Vadepu, S. K.; Patra, S.


    A Time Domain Impedance Probe (TDIP) measures electron density and electron neutral collision frequencies in the ionosphere. This instrument has been tested on a sounding rocket flight and is now being further developed to fly on a NASA Undergraduate Student Instrument Program (USIP) cubesat to be launched out of the ISS in 2019. Here we report on the development of a new combined TDIP and plasma wave instrument that can be used on cubesat platforms to measure local electron parameters, and also to receive or transmit electron scale waves. This combined instrument can be used to study short time and space scale phenomena in the upper ionosphere using only RF signals. The front end analog circuitry is dual-purposed to perform active or passive probing of the ambient plasma. Two dipole antennas are used, one is optimzed for impedance measurements, while the other is optimized for transmitter-receiver performance. We show our circuit realization, and initial results from laboratory measurements using the TDIP prototype modified for receiver function. We also show Finite Difference Time Domain (FDTD) simulations of an electrically long antenna immersed in a magnetized plasma used to optimize the transmitter receiver performance.

  16. Computer game-based and traditional learning method: a comparison regarding students' knowledge retention. (United States)

    Rondon, Silmara; Sassi, Fernanda Chiarion; Furquim de Andrade, Claudia Regina


    Educational computer games are examples of computer-assisted learning objects, representing an educational strategy of growing interest. Given the changes in the digital world over the last decades, students of the current generation expect technology to be used in advancing their learning requiring a need to change traditional passive learning methodologies to an active multisensory experimental learning methodology. The objective of this study was to compare a computer game-based learning method with a traditional learning method, regarding learning gains and knowledge retention, as means of teaching head and neck Anatomy and Physiology to Speech-Language and Hearing pathology undergraduate students. Students were randomized to participate to one of the learning methods and the data analyst was blinded to which method of learning the students had received. Students' prior knowledge (i.e. before undergoing the learning method), short-term knowledge retention and long-term knowledge retention (i.e. six months after undergoing the learning method) were assessed with a multiple choice questionnaire. Students' performance was compared considering the three moments of assessment for both for the mean total score and for separated mean scores for Anatomy questions and for Physiology questions. Students that received the game-based method performed better in the pos-test assessment only when considering the Anatomy questions section. Students that received the traditional lecture performed better in both post-test and long-term post-test when considering the Anatomy and Physiology questions. The game-based learning method is comparable to the traditional learning method in general and in short-term gains, while the traditional lecture still seems to be more effective to improve students' short and long-term knowledge retention.

  17. Private Cloud Communities for Faculty and Students

    Directory of Open Access Journals (Sweden)

    Daniel R. Tomal


    Full Text Available Massive open online courses (MOOCs and public and private cloud communities continue to flourish in the field of higher education. However, MOOCs have received criticism in recent years and offer little benefit to students already enrolled at an institution. This article advocates for the collaborative creation and use of institutional, program or student-specific private cloud communities developed as a way to promote academic identity, information dissemination, social discourse, and to form a bridge between faculty, administration and students. Concrete steps to build a private cloud are described. Placing a greater emphasis on meeting the needs of enrolled students versus engaging the masses in a MOOC for “edutainment” purposes is recommended.

  18. The effect of gender bias on medical students and career choices: a cross-sectional study

    Directory of Open Access Journals (Sweden)



    Full Text Available Dear Editor, Gender equality amongst healthcare professionals is no doubt paramount to allow both equal opportunity and provision of good quality healthcare. The General Medical Council encourages that all colleagues should be treated fairly, but studies have previously demonstrated gender bias against female medical students (1. Whether this might have any impact on the students’ decision-making process and career pathways has yet to be explored. We aimed to evaluate whether doctors gave students gender-specific advice and the extent to which this advice influenced the students. Furthermore, we explored whether students felt their gender affected their career choices. We carried out a cross-sectional national study of British clinical medical students. A standardised questionnaire was completed by 94 students (54.3% female. The response rate was 88.7%. Results showed that 43.6% (n=41 of students received career advice based purely on their gender, and 63.4% (n=26 of these said that this would influence their career choices. Importantly, 82.9% (n=34 of the students who received gender-specific advice were female. Additionally, 41.2% (n=21 of females felt their gender would restrict their career choices compared with only 11.6% (n=5 of males (p=0.00142. 37.3% (n=19 of females thought their gender would unfairly disadvantage their career progression compared to 4.65% (n=2 of males (p=0.00016. Our results highlighted that doctors gave more gender-specific advice to females compared to males, and that this advice significantly impacts students’ decision making process. Furthermore, females disproportionately felt their careers would be disadvantaged and restricted compared with males. This shows an enormous disparity between male and female attitudes towards medical careers. This can have both long and short-term effects on training, career choices and patient interaction. Further research investigating why females feel their gender will

  19. Science Inquiry as Knowledge Transformation: Investigating Metacognitive and Self-regulation Strategies to Assist Students in Writing about Scientific Inquiry Tasks (United States)

    Collins, Timothy A.


    Science inquiry is central to the science education reform efforts that began in the early 1990's. It is both a topic of instruction and a process to be experienced. Student engagement in the process of scientific inquiry was the focus of this study. The process of scientific inquiry can be conceived as a two-part task. In the initial part of the task, students identify a question or problem to study and then carry out an investigation to address the issue. In the second part of the task, students analyze their data to propose explanations and then report their findings. Knowing that students struggle with science inquiry tasks, this study sought to investigate ways to help students become more successful with the communication demands of science inquiry tasks. The study took place in a high school chemistry class. Students in this study completed a total of three inquiry tasks over the course of one school year. Students were split into four experimental groups in order to determine the effect of goal setting, metacognitive prompts, and sentence stems on student inquiry tasks. The quality of the student written work was assessed using a scoring rubric familiar to the students. In addition, students were asked at four different times in the school year to respond to a self-efficacy survey that measured student self-efficacy for chemistry content and science inquiry processes. Student self-efficacy for the process of scientific inquiry was positive and did not change over the course of the study while student scores on the science inquiry tasks rose significantly. The metacognitive prompts and instruction in goal setting did not have any effect on student inquiry scores. Results related to the effect of the sentence stems were mixed. An analysis of student work indicated that students who received high marks on their initial inquiry task in this study were the ones that adopted the use of the sentence stems. Students who received low marks on their initial inquiry

  20. 'Chaos' in superregenerative receivers

    International Nuclear Information System (INIS)

    Commercon, Jean-Claude; Badard, Robert


    The superregenerative principle has been known since the early 1920s. The circuit is extremely simple and extremely sensitive. Today, superheterodyne receivers generally supplant superregenerative receivers in most applications because there are several undesirable characteristics: poor selectivity, reradiation, etc. Superregenerative receivers undergo a revival in recent papers for wireless systems, where low cost and very low power consumption are relevant: house/building meters (such as water, energy, gas counter), personal computer environment (keyboard, mouse), etc. Another drawback is the noise level which is higher than that of a well-designed superheterodyne receiver; without an antenna input signal, the output of the receiver hears in an earphone as a waterfall noise; this sound principally is the inherent input noise amplified and detected by the circuit; however, when the input noise is negligible with respect of an antenna input signal, we are faced to an other source of 'noise' self-generated by the superregenerative working. The main objective of this paper concerns this self-generated noise coming from an exponential growing followed by a re-injection process for which the final state is a function of the phase of the input signal

  1. Influences on students' assistive technology use at school: the views of classroom teachers, allied health professionals, students with cerebral palsy and their parents. (United States)

    Karlsson, Petra; Johnston, Christine; Barker, Katrina


    This study explored how classroom teachers, allied health professionals, students with cerebral palsy, and their parents view high-tech assistive technology service delivery in the classroom. Semi-structured interviews with six classroom teachers and six parents and their children were conducted. Additionally, two focus groups comprising 10 occupational therapists and six speech pathologists were carried out. Ethical and confidentiality considerations meant that the groups were not matched. Results revealed that it is often untrained staff member who determine students' educational needs. The participants' experiences suggested that, particularly in mainstream settings, there is a need for support and guidance from a professional with knowledge of assistive technology who can also take a lead and guide classroom teachers in how to meet students' needs. Students' motivation to use the technology was also found to be critical for its successful uptake. The study points to the need for classroom teachers to be given sufficient time and skill development opportunities to enable them to work effectively with assistive technology in the classroom. The participants' experiences suggest that such opportunities are not generally forthcoming. Only in this way can it be ensured that students with disabilities receive the education that is their right. Implications for Rehabilitation Classroom teachers, allied health professionals, students, parents need ongoing support and opportunities to practise operational, strategic and linguistic skills with the assistive technology equipment. System barriers to the uptake of assistive technology need to be addressed. To address the lack of time available for training, programing and other support activities around assistive technology, dedicated administrative support is crucial. Professional development around the use of the quality low cost ICF-CY checklist is recommended for both school and allied health staff.

  2. The impact of lecture attendance and other variables on how medical students evaluate faculty in a preclinical program. (United States)

    Martin, Stanley I; Way, David P; Verbeck, Nicole; Nagel, Rollin; Davis, John A; Vandre, Dale D


    High-quality audiovisual recording technology enables medical students to listen to didactic lectures without actually attending them. The authors wondered whether in-person attendance affects how students evaluate lecturers. This is a retrospective review of faculty evaluations completed by first- and second-year medical students at the Ohio State University College of Medicine during 2009-2010. Lecture-capture technology was used to record all lectures. Attendance at lectures was optional; however, all students were required to complete lecturer evaluation forms. Students rated overall instruction using a five-option response scale. They also reported their attendance. The authors used analysis of variance to compare the lecturer ratings of attendees versus nonattendees. The authors included additional independent variables-year of student, student grade/rank in class, and lecturer degree-in the analysis. The authors analyzed 12,092 evaluations of 220 lecturers received from 358 students. The average number of evaluations per lecturer was 55. Seventy-four percent (n = 8,968 evaluations) of students attended the lectures they evaluated, whereas 26% (n = 3,124 evaluations) viewed them online. Mean lecturer ratings from attendees was 3.85 compared with 3.80 by nonattendees (P ≤ .05; effect size: 0.055). Student's class grade and year, plus lecturer degree, also affected students' evaluations of lecturers (effect sizes: 0.055-0.3). Students' attendance at lectures, year, and class grade, as well as lecturer degree, affect students' evaluation of lecturers. This finding has ramifications on how student evaluations should be collected, interpreted, and used in promotion and tenure decisions in this evolving medical education environment.

  3. NASA/DOD Aerospace Knowledge Diffusion Research Project. Paper 40: Technical communications in aerospace education: A study of AIAA student members (United States)

    Kennedy, John M.; Pinelli, Thomas E.; Barclay, Rebecca O.


    This paper describes the preliminary analysis of a survey of the American Institute of Aeronautics and Astronautics (AIAA) student members. In the paper we examine (1) the demographic characteristics of the students, (2) factors that affected their career decisions, (3) their career goals and aspirations, and (4) their training in technical communication and techniques for finding and using aerospace scientific and technical information (STI). We determine that aerospace engineering students receive training in technical communication skills and the use of STI. While those in the aerospace industry think that more training is needed, we believe the students receive the appropriate amount of training. We think that the differences between the amount of training students receive and the perception of training needs is related partially to the characteristics of the students and partially to the structure of the aerospace STI dissemination system. Overall, we conclude that the students' technical communication training and knowledge of STI, while limited by external forces, makes it difficult for students to achieve their career goals.

  7. An instructional intervention to encourage effective deep collaborative learning in undergraduate veterinary students. (United States)

    Khosa, Deep K; Volet, Simone E; Bolton, John R


    In recent years, veterinary education has received an increased amount of attention directed at the value and application of collaborative case-based learning. The benefit of instilling deep learning practices in undergraduate veterinary students has also emerged as a powerful tool in encouraging continued professional education. However, research into the design and application of instructional strategies to encourage deep, collaborative case-based learning in veterinary undergraduates has been limited. This study focused on delivering an instructional intervention (via a 20-minute presentation and student handout) to foster productive, collaborative case-based learning in veterinary education. The aim was to instigate and encourage deep learning practices in a collaborative case-based assignment and to assess the impact of the intervention on students' group learning. Two cohorts of veterinary students were involved in the study. One cohort was exposed to an instructional intervention, and the other provided the control for the study. The instructional strategy was grounded in the collaborative learning literature and prior empirical studies with veterinary students. Results showed that the intervention cohort spent proportionally more time on understanding case content material than did the control cohort and rated their face-to-face discussions as more useful in achieving their learning outcomes than did their control counterparts. In addition, the perceived difficulty of the assignment evolved differently for the control and intervention students from start to end of the assignment. This study provides encouraging evidence that veterinary students can change and enhance the way they interact in a group setting to effectively engage in collaborative learning practices.

  8. Educating medical students for work in culturally diverse societies. (United States)

    Loudon, R F; Anderson, P M; Gill, P S; Greenfield, S M


    Recent attention has focused on whether government health service institutions, particularly in the United Kingdom, reflect cultural sensitivity and competence and whether medical students receive proper guidance in this area. To systematically identify educational programs for medical students on cultural diversity, in particular, racial and ethnic diversity. The following databases were searched: MEDLINE (1963-August 1998); Bath International Data Service (BIDS) Institute for Scientific Information science and social science citation indexes (1981-August 1998); BIDS International Bibliography for the Social Sciences (1981-August 1998); and the Educational Resources Information Centre (1981-August 1998). In addition, the following online data sets were searched: Kings Fund; Centre for Ethnic Relations, University of Warwick; Health Education Authority; European Research Centre on Migration and Ethnic Relations, University of Utrecht; International Centre for Intercultural Studies, University of London; the Refugee Studies Programme, University of Oxford. Medical education and academic medicine journals (1994-1998) were searched manually and experts in medical education were contacted. Studies included in the analysis were articles published in English before August 1998 that described specific programs for medical students on racial and ethnic diversity. Of 1456 studies identified by the literature search, 17 met the criteria. Two of the authors performed the study selection independently. The following data were extracted: publication year, program setting, student year, whether a program was required or optional, the teaching staff and involvement of minority racial and ethnic communities, program length, content and teaching methods, student assessment, and nature of program evaluation. Of the 17 selected programs, 13 were conducted in North America. Eleven programs were exclusively for students in years 1 or 2. Fewer than half (n = 7) the programs were part of

  9. Teaching Medical Students Clinical Anesthesia. (United States)

    Curry, Saundra E


    allowed full access to patient care, including performing history and physical examinations, participating in the insertion of IVs and airway management. Simulation-based teaching was used by 82% of programs during medical student anesthesia clerkships. Sixty-eight percent of respondents reported that they have no formal training for their anesthesiology faculty teachers, 51% stated that they do not receive nonclinical time to teach, and 38% of respondents stated that they received some form of remuneration for teaching medical students, primarily nonclinical time. This article presents a summary of these survey results, provides a historical review of previous evaluations of teaching medical students clinical anesthesia, and discusses the contributions of anesthesiologists to medical student education.

  10. Predictors of well-being among college students. (United States)

    Ridner, S Lee; Newton, Karen S; Staten, Ruth R; Crawford, Timothy N; Hall, Lynne A


    Identification of health-related risk behaviors associated with well-being in college students is essential to guide the development of health promotion strategies for this population. The purposes were to evaluate well-being among undergraduate students and to identify health-related risk behaviors that predict well-being in this population. A cross-sectional Web-based survey of undergraduate students was conducted at a metropolitan university in the Southeast United States. A total of 568 students responded (response rate 14.2%). Data were collected on health-related risk behaviors using the National College Health Assessment II. Controlling demographic characteristics, the best predictive model included physical activity, current tobacco user, depression, ever received mental health services, and sleep quality, which was the strongest predictor (β = .45, p college students may be most beneficial in improving well-being.

  12. Student Engagement in a Computer Rich Science Classroom (United States)

    Hunter, Jeffrey C.

    The purpose of this study was to examine the student lived experience when using computers in a rural science classroom. The overarching question the project sought to examine was: How do rural students relate to computers as a learning tool in comparison to a traditional science classroom? Participant data were collected using a pre-study survey, Experience Sampling during class and post-study interviews. Students want to use computers in their classrooms. Students shared that they overwhelmingly (75%) preferred a computer rich classroom to a traditional classroom (25%). Students reported a higher level of engagement in classes that use technology/computers (83%) versus those that do not use computers (17%). A computer rich classroom increased student control and motivation as reflected by a participant who shared; "by using computers I was more motivated to get the work done" (Maggie, April 25, 2014, survey). The researcher explored a rural school environment. Rural populations represent a large number of students and appear to be underrepresented in current research. The participants, tenth grade Biology students, were sampled in a traditional teacher led class without computers for one week followed by a week using computers daily. Data supported that there is a new gap that separates students, a device divide. This divide separates those who have access to devices that are robust enough to do high level class work from those who do not. Although cellular phones have reduced the number of students who cannot access the Internet, they may have created a false feeling that access to a computer is no longer necessary at home. As this study shows, although most students have Internet access, fewer have access to a device that enables them to complete rigorous class work at home. Participants received little or no training at school in proper, safe use of a computer and the Internet. It is clear that the majorities of students are self-taught or receive guidance

  13. 3D-RTK Capability of Single Gnss Receivers (United States)

    Stempfhuber, W.


    Small, aerial objects are now being utilised in many areas of civil object capture and monitoring. As a rule, the standard application of a simple GPS receiver with code solutions serves the 3D-positioning of the trajectories or recording positions. Without GPS correction information, these can be calculated at an accuracy of 10-20 metres. Corrected code solutions (DGPS) generally lie in the metre range. A precise 3D-positioning of the UAV (unmanned aerial vehicle) trajectories in the centimetre range provides significant improvements. In addition, the recording time of each sensor can be synchronized with the exact time stamp of the GNSS low-cost system. In recent years, increasing works on positioning from L1 GPS raw data have been published. Along with this, the carrier phase measurements with the established evaluation algorithms are analysed in the post processing method to centimetre-exact positions or to high-precision 3D trajectories [e.g. Schwieger and Gläser, 2005 or Korth and Hofmann 20011]. The use of reference information from local reference stations or a reference network serves the purpose of carrier phase ambiguity resolution. Furthermore, there are many activities worldwide in the area of PPP techniques (Precise Point Positioning). However, dual frequency receivers are primarily used in this instance. Moreover, very long initialisation times must be scheduled for this. A research project on the subject of low-cost RTK GNSS was developed for real-time applications at the Beuth Hochschule für Technik Berlin University of Applied Sciences [Stempfhuber 2012]. The overall system developed for the purpose of real-time applications with centimetre accuracy is modularly constructed and can be used for various applications ( With hardware costing a few hundred Euro and a total weight of 500-800 g (including the battery), this system is ideally suited for UAV applications. In addition, the

    Khan, Muhammad Alamgir; Shabbir, Faizania; Qamar, Khadija; Rajput, Tausif Ahmed


    To observe the effect of skill lab training on academic performance of final year medical students in terms of marks obtained in long case, short case, objective structured clinical examination and viva. The cross-sectional comparative study was conducted at Army Medical College, Rawalpindi from February to April 2015. Two batches of final year MBBS were recruited for the study. Batch 1 received conventional training, and Batch 2 received skill lab training. The performance of students was assessed by comparing the marks obtained in long case, short case, objective structured clinical examination and viva. Data was analysed using SPSS 23. Of the 335 subjects, 168(50.1%) were male and 167(49.9%) were female students with a mean age of 21.79±1.02 years. Batch 1 had 151(45%) students and Batch 2 had 184(55%). Batch 2 got significantly higher marks in long case, short case and objective structured clinical examination (p0.05).

  15. Turkish Final Year Medical Students' Exposure to and Attitudes Concerning Drug Company Interactions: A Perspective from a Minimally Regulated Environment for Medical Students. (United States)

    Beyhun, Nazim Ercument; Kolayli, Cevriye Ceyda; Can, Gamze; Topbas, Murat


    Interactions between drug companies and medical students may affect evidence-based medical practice and patient safety. The aim of this study was to assess drug company-medical student interactions in a medical faculty where limited specific national or institutional regulations apply between drug companies and medical students. The objectives of the study were to determine the exposure and attitudes of final year medical students in terms of drug company-medical student and physician interactions, to identify factors affecting those attitudes and to provide data for policymakers working on the regulation of interactions between drug companies and medical students. This anonymous questionnaire-based study of 154 medical final year medical students at the Karadeniz Technical University Medical Faculty, Trabzon, Turkey, in April and May 2015 attracted a response rate of 92.2% (n/N, 154/164). Exposure to interaction with a pharmaceutical representative was reported by 90.3% (139/154) of students, and 68.8% (106/154) reported experiencing such interaction alongside a resident. In addition, 83.7% (128/153) of students reported an interaction during internship. Furthermore, 69.9% (107/153) of students agreed that interactions influence physicians' prescription preferences, while 33.1% (51/154) thought that a medical student should never accept a gift from a drug company and 24.7% (38/154) agreed with the proposition that "drug companies should not hold activities in medical faculties". Students with rational prescription training expressed greater agreement with the statement "I am skeptical concerning the information provided by drug companies during interactions" than those who had not received such training, and this finding was supported by logistic regression [O.R.(C.I), p -3.7(1.2-11.5), p = 0.022]. Acceptance of advertisement brochures was found to significantly reduce the level of agreement with the proposition that "A physician should not accept any gift from a

  17. Doing peer review and receiving feedback: impact on scientific literacy and writing skills. (United States)

    Geithner, Christina A; Pollastro, Alexandria N


    Doing peer review has been effectively implemented to help students develop critical reading and writing skills; however, its application in Human Physiology programs is limited. The purpose of the present study was to determine the impact of peer review on Human Physiology majors' perceptions of their scientific literacy and writing skills. Students enrolled in the Scientific Writing course completed multiple writing assignments, including three revisions after receiving peer and instructor feedback. Students self-assessed their knowledge, skills, and attitudes related to science and writing in pre- and postcourse surveys (n = 26 with complete data). Seven survey items related to scientific literacy and writing skills impacted by peer review were selected for analysis. Scores on these survey items were summed to form a composite self-rating score. Responses to two questions regarding the most useful learning activities were submitted to frequency analysis. Mean postcourse scores for individual survey items and composite self-rating scores were significantly higher than precourse means (P writing skills. In conclusion, peer review is an effective teaching/learning approach for improving undergraduate Human Physiology majors' knowledge, skills, and attitudes regarding science and scientific writing.

    de Vibe, Michael; Solhaug, Ida; Tyssen, Reidar; Friborg, Oddgeir; Rosenvinge, Jan H; Sørlie, Tore; Bjørndal, Arild


    Distress and burnout among medical and psychology professionals are commonly reported and have implications for the quality of patient care delivered. Already in the course of university studies, medicine and psychology students report mental distress and low life satisfaction. There is a need for interventions that promote better coping skills in students in order to prevent distress and future burnout. This study examines the effect of a seven-week Mindfulness-Based Stress Reduction (MBSR) programme on mental distress, study stress, burnout, subjective well-being, and mindfulness of medical and psychology students. A total of 288 students (mean age = 23 years, 76% female) from the University of Oslo and the University of Tromsø were randomly allocated to an intervention or control group. The control group continued with their standard university courses and received no intervention. Participants were evaluated using self-reported measures both before and after the intervention. These were: the 'General Health Questionnaire, Maslach Burnout Inventory Student version, Perceived Medical School Stress, Subjective Well-being, and Five Facet Mindfulness Questionnaire' and additional indices of compliance. Following the intervention, a moderate effect on mental distress (Hedges'g 0.65, CI = .41, .88), and a small effect on both subjective well-being (Hedges'g 0.40, CI = .27, .63) and the mindfulness facet 'non-reacting' (Hedges'g 0.33, CI = .10, .56) were found in the intervention group compared with the control group. A higher level of programme attendance and reported mindfulness exercises predicted these changes. Significant effects were only found for female students who additionally reported reduced study stress and an increase in the mindfulness facet 'non-judging'. Gender specific effects of participation in the MBSR programme have not previously been reported, and gender differences in the present study are discussed. Female medical and psychology

  1. Immunization Status Against Hepatitis B Among Iranian Junior Medical, Nursing, and Obstetrics Students With Different Vaccination Patterns

    Directory of Open Access Journals (Sweden)



    Full Text Available Background Since the protection time by hepatitis B (HB vaccination is unclear, the strategy of immunization of junior students who previously received hepatitis vaccine is controversial. Objectives This study aimed to determine the status of immunity to hepatitis B in junior medical, nursing and obstetrics students with different hepatitis B virus (HBV vaccination patterns. Patients and Methods In an analytical cross-sectional study, 255 junior medical sciences students were tested for quantitative antibodies to hepatitis B surface antigen (anti-HBs. The proportion of protective immunity was compared in different vaccination patterns. Results Vaccination coverage rates were 74.1%. About half the participants didn’t show serological evidence of protective immunity; 68.9% had their last shot more than 10 years ago and 30.4% had a vaccination history of five years or less (P < 0.001. Geometric mean level of anti-HBs titer among students, who had received a primary series vaccine at birth, was significantly lower than students who had started vaccination at an older age (P < 0.001. Also, analysis of variance for geometric mean of anti-HBs titer showed significant differences between groups based on injection time from the last shot (P < 0.001 (post hoc comparisons resulted in a P value of < 0.001 for birth versus < 5 year group, and P < 0.001 for the 5 to 10 year group. The lowest rate of non-protective level belonged to participants with complete three doses and a booster additional shot (27.1%. The final model for independent predictors of anti-HBs positive status was made by a binary logistic regression analysis. The model included presence of a booster dose, injection time from last shot, and discipline of study. Conclusions This study shows lower anti-HBs among students who were vaccinated at infancy compared to those vaccinated at older childhood or adolescence. Also, subsequent measurement of anti-HBs level at the time of entrance to

  3. The Surprising Impact of Seat Location on Student Performance (United States)

    Perkins, Katherine K.; Wieman, Carl E.


    Every physics instructor knows that the most engaged and successful students tend to sit at the front of the class and the weakest students tend to sit at the back. However, it is normally assumed that this is merely an indication of the respective seat location preferences of weaker and stronger students. Here we present evidence suggesting that in fact this may be mixing up the cause and effect. It may be that the seat selection itself contributes to whether the student does well or poorly, rather than the other way around. While a number of studies have looked at the effect of seat location on students, the results are often inconclusive, and few, if any, have studied the effects in college classrooms with randomly assigned seats. In this paper, we report on our observations of a large introductory physics course in which we randomly assigned students to particular seat locations at the beginning of the semester. Seat location during the first half of the semester had a noticeable impact on student success in the course, particularly in the top and bottom parts of the grade distribution. Students sitting in the back of the room for the first half of the term were nearly six times as likely to receive an F as students who started in the front of the room. A corresponding but less dramatic reversal was evident in the fractions of students receiving As. These effects were in spite of many unusual efforts to engage students at the back of the class and a front-to-back reversal of seat location halfway through the term. These results suggest there may be inherent detrimental effects of large physics lecture halls that need to be further explored.

  4. Plasma Aluminum Concentrations in Pediatric Patients Receiving Long-Term Parenteral Nutrition. (United States)

    Courtney-Martin, Glenda; Kosar, Christina; Campbell, Alison; Avitzur, Yaron; Wales, Paul W; Steinberg, Karen; Harrison, Debra; Chambers, Kathryn


    Patients receiving long-term parenteral nutrition (PN) are at increased risk of aluminium (Al) toxicity because of bypass of the gastrointestinal tract during PN infusion. Complications of Al toxicity include metabolic bone disease (MBD), Al-associated encephalopathy in adults, and impaired neurological development in preterm infants. Unlike the United States, there are no regulations regarding Al content of large- and small-volume parenterals in Canada. We, therefore, aimed to present our data on plasma Al concentration and Al intake from our cohort of pediatric patients receiving long-term PN. Plasma Al concentration was retrospectively gathered from the patient charts of all 27 patients with intestinal failure (IF) receiving long-term PN at The Hospital for Sick Children, Toronto, Canada, and compared with age- and sex-matched controls recruited for comparison. In addition, Al concentration was measured in PN samples collected from 10 randomly selected patients with IF and used to determine their Al intake. The plasma Al concentration of patients with IF receiving long-term PN was significantly higher than that of control participants (1195 ± 710 vs 142 ± 63 nmol/L; P Parenteral and Enteral Nutrition.

  10. A comparison of the effects of computer-enhanced with traditional instruction on the learning outcomes of high-school students in anatomy classes (United States)

    Kim, Norma B.

    The primary purpose of this study was to assess the effects of computer-enhanced instruction (CEI), using A.D.A.M.sp°ler The Inside Story (1997a) anatomy software, compared with traditional instruction (TI) on student learning outcomes in high school anatomy classes. Learning outcomes are comprised of student achievement. The secondary purpose of this study was to determine whether there were relationships between learning style theories and student learning outcomes. The study was conducted in two human anatomy classes at a suburban high school near Pittsburgh. One class was chosen randomly to receive CEI. The other class received identical instruction but with no software enhancement. The same instructor taught both classes. Before the study began, the Thurstone and Jeffrey Closure Flexibility Test was administered to measure students' visual perception levels and classify them as either visually perceptive or nonvisually perceptive. The Dunn Dunn and Price Learning Style Inventory was administered to the students to identify their learning styles. CEI students worked in groups at computers using A.D.A.M.sp°ler software. Students in the TI class worked in groups on word processors for written assignments. Students in both classes received the same lectures, assignments, and study guides. After the three-week instruction period, a posttest was administered to each student in both classes to compare their achievement in the endocrine unit. Two way ANOVA revealed that there was no significant difference between the mean posttest scores of students who received CEI and TI. However, a significant difference in mean posttest scores was found between visually perceptive students and nonvisually perceptive students (p < .01). There was no interaction between the instruction methods and students' visual perception levels. Regardless of the type of instruction received, visually perceptive students scored higher than nonvisually perceptive students on the posttest

  11. Fast converging minimum probability of error neural network receivers for DS-CDMA communications. (United States)

    Matyjas, John D; Psaromiligkos, Ioannis N; Batalama, Stella N; Medley, Michael J


    We consider a multilayer perceptron neural network (NN) receiver architecture for the recovery of the information bits of a direct-sequence code-division-multiple-access (DS-CDMA) user. We develop a fast converging adaptive training algorithm that minimizes the bit-error rate (BER) at the output of the receiver. The adaptive algorithm has three key features: i) it incorporates the BER, i.e., the ultimate performance evaluation measure, directly into the learning process, ii) it utilizes constraints that are derived from the properties of the optimum single-user decision boundary for additive white Gaussian noise (AWGN) multiple-access channels, and iii) it embeds importance sampling (IS) principles directly into the receiver optimization process. Simulation studies illustrate the BER performance of the proposed scheme.

  12. The price of soliciting and receiving negative feedback: self-verification theory as a vulnerability to depression theory. (United States)

    Joiner, T E


    The hypothesis that people who seek and receive negative feedback are vulnerable to increases in depressed symptoms was tested among 100 undergraduates and their roommates. Students and roommates completed questionnaires on their views of each other and on their own levels of negative feedback seeking, depressed and anxious symptoms, negative and positive affect, and self-esteem. Three weeks later, students and roommates completed the same questionnaires. Results were, in general, consistent with prediction. Students who reported an interest in their roommates' negative feedback and who lived with a roommate who viewed them negatively were at heightened risk for increases in depressed symptoms. These results could not be explained in terms of the variables' relations to trait self-esteem. The symptom specificity of the effect was moderately supported. Implications for work on interpersonal vulnerability to depression are discussed.

  14. Bridging the gap between textbook and maternity patient: a nurse-developed teaching model for first-year medical students. (United States)

    Cooksey, Nancy Rumsey


    Providing more opportunities for first-year medical students to interact with patients in clinical settings is a current discussion topic in medical student education reform. Early clinical experience helps students bridge the gap between textbook and patient while observing patient-centered care, and serves as a first step for students to develop the skills needed to work cooperatively as members of a multidisciplinary health care team. The author developed a model to provide perinatal education to first-year medical students, consistent with the concept of interprofessional education. Primarily first-year medical students participated in the nurse-developed education model, a component of a noncredit extracurricular, student-run perinatal program at a Midwestern university medical center. Students were placed at the bedsides of hospitalized women to provide support and education to them during perinatal procedures, labor, childbirth, and cesarean delivery. A total of 350 students participated over a period of 13 school calendar years. Students remarked that participation in the program reinforced the importance of their concurrent anatomy and physiology classes. They observed interdependence and cooperation among the members of the health care team caring for women, and their evaluations of their experiences at the bedside were highly positive. Women consistently expressed appreciation for the additional individualized attention and education received from our student and nurse team. Nurses can enhance the learning of first-year medical students in the maternity care clinical setting. This nurse-developed education program provided students with a variety of vivid clinical experiences with maternity patients. © 2010, Copyright the Author.

  19. How can students contribute? A qualitative study of active student involvement in development of technological learning material for clinical skills training. (United States)

    Haraldseid, Cecilie; Friberg, Febe; Aase, Karina


    Policy initiatives and an increasing amount of the literature within higher education both call for students to become more involved in creating their own learning. However, there is a lack of studies in undergraduate nursing education that actively involve students in developing such learning material with descriptions of the students' roles in these interactive processes. Explorative qualitative study, using data from focus group interviews, field notes and student notes. The data has been subjected to qualitative content analysis. Active student involvement through an iterative process identified five different learning needs that are especially important to the students: clarification of learning expectations, help to recognize the bigger picture, stimulation of interaction, creation of structure, and receiving context- specific content. The iterative process involvement of students during the development of new technological learning material will enhance the identification of important learning needs for students. The use of student and teacher knowledge through an adapted co-design process is the most optimal level of that involvement.

    A Q-band two-beam cryogenic receiver for the Tianma Radio Telescope (TMRT) has been developed, and it uses the independently-developed key microwave and millimeter-wave components operating from 35 to 50GHz with a fractional bandwidth of 35%. The Q-band receiver consists of three parts: optics, cold unit assembly and warm unit assembly, and it can receive simultaneously the left-handed and right-handed circularly polarized waves. The cold unit assembly of each beam is composed of a feed horn, a noise injection coupler, a differential phase shifter, an orthomode transducer and two low-noise amplifiers, and it works at a temperature range near 20 K to greatly improve the detection sensitivity of the receiving system. The warm unit assembly includes four radio-frequency amplifiers, four radio-frequency high-pass filters, four waveguide biased mixers, four 4–12 GHz intermediate-frequency amplifiers and one 31–38 GHz frequency synthesizer. The measured Q-band four-channel receiver noise temperatures are roughly 30–40 K. In addition, the single-dish spectral line and international very long baseline interferometry (VLBI) observations between the TMRT and East Asia VLBI Network at the Q-band have been successfully carried out, demonstrating the advantages of the TMRT equipped with the state-of-the-art Q-band receiver.

    Youth stroke education is promising for the spread of stroke awareness. The aim of this study was to examine whether our stroke awareness teaching materials without teacher's participation can increase student awareness to act fast on suspected stroke signs. We used the face, arm, speech, and time (FAST) mnemonic derived from the Cincinnati Prehospital Stroke Scale. Seventy-three students of the second grade and 72 students of the third grade (age range, 13-15 years) in a junior high school were enrolled in the study. The students were divided into 2 groups: students who received a teacher's lesson (group I) and those who did not receive a teacher's lesson (group II). Students in group II watched an animated cartoon and read a Manga comic in class. All students took the educational aids home, including the Manga comic and magnetic posters printed with the FAST message. Questionnaires on stroke knowledge were examined at baseline and immediately and 3 months after receiving the intervention. At 3 months after the intervention, a significant improvement in understanding the FAST message was confirmed in both the groups (group I, 85%; group II, 94%). Significant increases in the knowledge of risk factors were not observed in each group. Our education materials include a Manga comic, an animated cartoon, and a magnetic poster, without an accompanying teacher's lesson can increase stroke awareness, including the FAST message, in junior high school students.

  5. Transmit-receive eddy current probes

    International Nuclear Information System (INIS)

    Obrutsky, L.S.; Sullivan, S.P.; Cecco, V.S.


    In the last two decades, due to increased inspection demands, eddy current instrumentation has advanced from single-frequency, single-output instruments to multifrequency, computer-aided systems. This has significantly increased the scope of eddy current testing, but, unfortunately, it has also increased the cost and complexity of inspections. In addition, this approach has not always improved defect detectability or signal-to-noise. Most eddy current testing applications are still performed with impedance probes, which have well known limitations. However, recent research at AECL has led to improved eddy current inspections through the design and development of transmit-receive (T/R) probes. T/R eddy current probes, with laterally displaced transmit and receive coils, present a number of advantages over impedance probes. They have improved signal-to-noise ratio in the presence of variable lift-off compared to impedance probes. They have strong directional properties, permitting probe optimization for circumferential or axial crack detection, and possess good phase discrimination to surface defects. They can significantly increase the scope of eddy current testing permitting reliable detection and sizing of cracks in heat exchanger tubing as well as in welded areas of both ferritic and non-ferromagnetic components. This presentation will describe the operating principles of T/R probes with the help of computer-derived normalized voltage diagrams. We will discuss their directional properties and analyze the advantages of using single and multiple T/R probes over impedance probes for specific inspection cases. Current applications to surface and tube testing and some typical inspection results will be described. (author)

  10. UWB delay and multiply receiver

    Energy Technology Data Exchange (ETDEWEB)

    Dallum, Gregory E.; Pratt, Garth C.; Haugen, Peter C.; Romero, Carlos E.


    An ultra-wideband (UWB) delay and multiply receiver is formed of a receive antenna; a variable gain attenuator connected to the receive antenna; a signal splitter connected to the variable gain attenuator; a multiplier having one input connected to an undelayed signal from the signal splitter and another input connected to a delayed signal from the signal splitter, the delay between the splitter signals being equal to the spacing between pulses from a transmitter whose pulses are being received by the receive antenna; a peak detection circuit connected to the output of the multiplier and connected to the variable gain attenuator to control the variable gain attenuator to maintain a constant amplitude output from the multiplier; and a digital output circuit connected to the output of the multiplier.

  11. Wideband CMOS receivers

    CERN Document Server

    Oliveira, Luis


    This book demonstrates how to design a wideband receiver operating in current mode, in which the noise and non-linearity are reduced, implemented in a low cost single chip, using standard CMOS technology.  The authors present a solution to remove the transimpedance amplifier (TIA) block and connect directly the mixer’s output to a passive second-order continuous-time Σ∆ analog to digital converter (ADC), which operates in current-mode. These techniques enable the reduction of area, power consumption, and cost in modern CMOS receivers.

  12. Bringing Student Voices into the University Archives:
 A Student Organization Documentation Initiative Case Study

    Directory of Open Access Journals (Sweden)

    Jenifer Becker


    Full Text Available In Brief The undergraduate student experience has long been poorly and selectively captured by university archives. Though student narratives have always been essential for creating a complete history of the university, current nationwide student protests have made these voices all the more important to capture. As students engage in activism, regarding issues relevant to student life and wellbeing such as Title IX violations, tuition hikes, and racism on and off campus, college and university archives must go to additional lengths to document these activities.

  13. Knowledge, aptitudes, and preferences in implant dentistry teaching/training among undergraduate dental students at the University of Barcelona (United States)

    Berástegui-Jimeno, Esther; Gay-Escoda, Cosme


    Background Oral implant rehabilitation should be considered a treatment option for any edentulous patient and Implant Dentistry is currently a discipline taught in the undergraduate formation. The level of knowledge acquired and how the students perceive the quality of training in Implant Dentistry could assess to know if it is necessary to improve the syllabus. Material and Methods A questionnaire was developed with 11 questions: Basic knowledge (7); Perception of training received (2); Ways in which students would receive training (2). To be responded anonymously and voluntarily for undergraduates students in the Faculty of Dentistry (University of Barcelona, Spain). Results One hundred and seven students, 76 third year (Group A) and 31 fourth year (Group B) answered the questionnaire. In Group A, 98.68% of students and in Group B 93.54% believed they were poorly informed; 100% of both groups would prefer to receive more training as part of the degree or as postgraduate training through modular courses imparted by experts (A: 71,05%, B: 70,96%) Training through postgraduate programs or training given by private businesses were the least desirable options (A: 42%, B: 64.51%). Questions about basic knowledge acquired received varying responses, which might indicate a certain level of confusion in this area. Conclusions The undergraduate syllabus must be revised to include sufficient content and training to allow the student to indicate implant-based treatments based on evidence. Students would prefer training to be included in the undergraduate syllabus. Key words:Dental implants, dental students, dental education, dental syllabus, implant dentistry. PMID:28578375

    Full Text Available Recent research and development show promising use of high-performance solid-state receivers of the electromagnetic radiation. These receivers are based on the low-barrier Schottky diodes. The approach to the design of the receivers on the basis of delta-doped low-barrier Schottky diodes with beam leads without bias is especially actively developing because for uncooled receivers of the microwave radiation these diodes have virtually no competition. The purpose of this work is to improve the main parameters and characteristics that determine the practical relevance of the receivers of mid-infrared electromagnetic radiation at the operating room temperature by modifying the electrodes configuration of the diode and optimizing the distance between them. Proposed original design solution of the integrated receiver of mid-infrared radiation on the basis of the low-barrier Schottky diodes with beam leads allows to effectively adjust its main parameters and characteristics. Simulation of the electromagnetic characteristics of the proposed receiver by using the software package HFSS with the basic algorithm of a finite element method which implemented to calculate the behavior of electromagnetic fields on an arbitrary geometry with a predetermined material properties have shown that when the inner parts of the electrodes of the low-barrier Schottky diode is performed in the concentric elliptical convex-concave shape, it can be reduce the reflection losses to -57.75 dB and the standing wave ratio to 1.003 while increasing the directivity up to 23 at a wavelength of 6.09 μm. At this time, the rounded radii of the inner parts of the anode and cathode electrodes are equal 212 nm and 318 nm respectively and the gap setting between them is 106 nm. These parameters will improve the efficiency of the developed infrared optical-promising and electronic equipment for various purposes intended for work in the mid-infrared wavelength range.

    Full Text Available Background and Aims: Regional analgesia is commonly used for the relief of labour pain, Prolongation of analgesia can be achieved by adjuvant medications. The aim of this randomised controlled trial was to evaluate the efficacy of intrathecal levobupivacaine with dexamethasone for labour analgesia. Methods: A total of 80 females were included in this study, all were primigravidas undergoing vaginal delivery with cervical dilatation ≥4 cm and 50% or more effacement. Forty females were included randomly in either Group L (received intrathecal levobupivacaine 0.25% in 2 mL or Group LD (received intrathecal levobupivacaine 0.25% combined with dexamethasone 4 mg in 2 mL. The primary outcome was the duration of spinal analgesia. Secondary outcomes included the total dose of epidural local anaesthetic given, time to delivery, neonatal outcome and adverse effects. Results: The duration of spinal analgesia was significantly longer in the LD group compared with L group (80.5 ± 12.4 min vs. 57.1 ± 11.5 min, respectively; P< 0.001. In Group LD compared with Group L, time from spinal analgesia to delivery was significantly lower (317.4 ± 98.9 min vs. 372.4 ± 118.8 min, respectively; P = 0.027, and total epidural levobupivacaine consumption was significantly lower (102.4 ± 34.8 mg vs. 120.1 ± 41.9 mg, respectively; P = 0.027. The two groups were comparable with respect to characteristics of sensory and motor block, haemodynamic parameters, pain scores, neonatal outcome and frequency of adverse effects. Conclusion: Intrathecal dexamethasone plus levobupivacaine prolongs the duration of spinal analgesia during combined spinal-epidural CSE for labour analgesia.

  16. Towards full band colorless reception with coherent balanced receivers. (United States)

    Zhang, Bo; Malouin, Christian; Schmidt, Theodore J


    In addition to linear compensation of fiber channel impairments, coherent receivers also provide colorless selection of any desired data channel within multitude of incident wavelengths, without the need of a channel selecting filter. In this paper, we investigate the design requirements for colorless reception using a coherent balanced receiver, considering both the optical front end (OFE) and the transimpedance amplifier (TIA). We develop analytical models to predict the system performance as a function of receiver design parameters and show good agreement against numerical simulations. At low input signal power, an optimum local oscillator (LO) power is shown to exist where the thermal noise is balanced with the residual LO-RIN beat noise. At high input signal power, we show the dominant noise effect is the residual self-beat noise from the out of band (OOB) channels, which scales not only with the number of OOB channels and the common mode rejection ratio (CMRR) of the OFE, but also depends on the link residual chromatic dispersion (CD) and the orientation of the polarization tributaries relative to the receiver. This residual self-beat noise from OOB channels sets the lower bound for the LO power. We also investigate the limitations imposed by overload in the TIA, showing analytically that the DC current scales only with the number of OOB channels, while the differential AC current scales only with the link residual CD, which induces high peak-to-average power ratio (PAPR). Both DC and AC currents at the input to the TIA set the upper bounds for the LO power. Considering both the OFE noise limit and the TIA overload limit, we show that the receiver operating range is notably narrowed for dispersion unmanaged links, as compared to dispersion managed links. © 2012 Optical Society of America

  17. A Novel Approach to Medical Student Peer-assisted Learning Through Case-based Simulations. (United States)

    Jauregui, Joshua; Bright, Steven; Strote, Jared; Shandro, Jamie


    Peer-assisted learning (PAL) is the development of new knowledge and skills through active learning support from peers. Benefits of PAL include introduction of teaching skills for students, creation of a safe learning environment, and efficient use of faculty time. We present a novel approach to PAL in an emergency medicine (EM) clerkship curriculum using an inexpensive, tablet-based app for students to cooperatively present and perform low-fidelity, case-based simulations that promotes accountability for student learning, fosters teaching skills, and economizes faculty presence. We developed five clinical cases in the style of EM oral boards. Fourth-year medical students were each assigned a unique case one week in advance. Students also received an instructional document and a video example detailing how to lead a case. During the 90-minute session, students were placed in small groups of 3-5 students and rotated between facilitating their assigned cases and participating as a team for the cases presented by their fellow students. Cases were supplemented with a half-mannequin that can be intubated, airway supplies, and a tablet-based app (SimMon, $22.99) to remotely display and update vital signs. One faculty member rotated among groups to provide additional assistance and clarification. Three EM faculty members iteratively developed a survey, based on the literature and pilot tested it with fourth-year medical students, to evaluate the course. 135 medical students completed the course and course evaluation survey. Learner satisfaction was high with an overall score of 4.6 on a 5-point Likert scale. In written comments, students reported that small groups with minimal faculty involvement provided a safe learning environment and a unique opportunity to lead a group of peers. They felt that PAL was more effective than traditional simulations for learning. Faculty reported that students remained engaged and required minimal oversight. Unlike other simulations, our

  18. Students-as-partners’ scheme enhances postgraduate students’ employability skills while addressing gaps in bioinformatics education (United States)

    Mello, Luciane V.; Tregilgas, Luke; Cowley, Gwen; Gupta, Anshul; Makki, Fatima; Jhutty, Anjeet; Shanmugasundram, Achchuthan


    Abstract Teaching bioinformatics is a longstanding challenge for educators who need to demonstrate to students how skills developed in the classroom may be applied to real world research. This study employed an action research methodology which utilised student–staff partnership and peer-learning. It was centred on the experiences of peer-facilitators, students who had previously taken a postgraduate bioinformatics module, and had applied knowledge and skills gained from it to their own research. It aimed to demonstrate to peer-receivers, current students, how bioinformatics could be used in their own research while developing peer-facilitators’ teaching and mentoring skills. This student-centred approach was well received by the peer-receivers, who claimed to have gained improved understanding of bioinformatics and its relevance to research. Equally, peer-facilitators also developed a better understanding of the subject and appreciated that the activity was a rare and invaluable opportunity to develop their teaching and mentoring skills, enhancing their employability.

  19. Student Perceptions of Their Biology Teacher's Interpersonal Teaching Behaviors and Student Achievement (United States)

    Madike, Victor N.

    Inadequate student-teacher interactions in undergraduate courses have been linked to poor student performance. Researchers have noted that students' perceptions of student-teacher relationships may be an important factor related to student performance. The administration of a Mid-Atlantic community college prioritized increasing undergraduate biology student performance. The purpose of this quantitative study was to examine the relationship between students' biology achievement and their perceptions of interpersonal teaching behaviors and student-teacher interactions in introductory biology courses. Leary's theory on interpersonal communication and the systems communication theory of Watzlawick, Beavin, and Jackson served as the theoretical foundation. The Wubbel's Likert-scale questionnaire on student-teacher interactions was administered to 318 undergraduate biology students. Non-parametric Spearman's rank correlations revealed a significant direct correlation between students' grades and their perceptions of teachers' interpersonal teaching behaviors. The relationship between student achievement and students' perceptions of student-teacher interactions prompted the recommendation for additional study on the importance of student-teacher interactions in undergraduate programs. A recommendation for local practice included faculty development on strategies for improving student-teacher interactions. The study's implications for positive social change include increased understanding for administrators and instructors on the importance of teacher-student interactions at the community college level.

  20. The Analysis of Liquidity and Receivables as a Component of Corporate Financial Management

    Feshchenko Oleh Р.


    Full Text Available The article is aimed at the analysis of liquidity and receivables of corporations and substantiation of proposals as to its improvement as part of the management of financial status of companies. The instruments, methodical techniques, tasks, and stages of managing the accounts receivable were generalized. It has been substantiated that, at the current stage of development of Ukraine’s economy, it appears not sufficient to apply the coefficient analysis only, there is a need to supplement it by the regression analysis of the panel data, allowing for the temporal and spatial characteristics of the sample. The development of additional indicators for the monitoring of receivables can be suggested as recommendations for the studied corporations in order to reduce future risks of non-recovery and financial deterioration. Prospect for further research is an in-depth regression analysis of the panel data in terms of the measures to refinance receivables and the financial dynamics of companies.
