    The CanMEDS framework is ubiquitous in Canadian postgraduate medical education; however, training programs do not have a universal method of assessing competence. We set out to develop a novel portfolio that allowed trainees to generate a longitudinal record of their training and development within the framework. The portfolio provided an objective means for the residency program director to document and evaluate resident progress within the CanMEDS roles.

    The trainee-held learning portfolio is integral to the foundation programme in the UK. In the Northern Deanery, portfolio assessment is standardised through the Annual Review of Competence Progression (ARCP) process. In this study we aimed to establish how current trainees evaluate portfolio-based learning and ARCP, and how these attitudes may have changed since the foundation programme was first introduced. Deanery-wide trainee attitudes were surveyed by an electronic questionnaire in 2009 and compared with perceptions recorded during the pilot phase (2004-2005).  Many trainees continue to view the e-portfolio negatively. Indeed, significantly fewer trainees in 2009 thought that the e-portfolio was a 'good idea' or a 'worthwhile investment of time' than in 2005. Trainees remain unconvinced about the educational value of the e-portfolio: fewer trainees in 2009 regarded it as a tool that might help focus on training or recognise individual strengths and weaknesses. Issues around unnecessary bureaucracy persist. Current trainees tend to understand how to use the e-portfolio, but many did not know how much, or what evidence to collect. Few supervisors were reported to provide useful guidance on the portfolio. ARCP encouraged portfolio completion but did not give meaningful feedback to drive future learning.   Continued support is needed for both trainees and supervisors in portfolio-building skills and in using the e-portfolio as an educational tool. Trainee-tailored feedback is needed to ensure that portfolio-based assessment promotes lifelong, self-directed and reflective learners. © Blackwell Publishing Ltd 2013.

    We present a novel online ensemble learning strategy for portfolio selection. The new strategy controls and exploits any set of commission-oblivious portfolio selection algorithms. The strategy handles transaction costs using a novel commission avoidance mechanism. We prove a logarithmic regret bound for our strategy with respect to optimal mixtures of the base algorithms. Numerical examples validate the viability of our method and show significant improvement over the state-of-the-art.

    How do people make investment decisions when they receive outcome feedback? We examined how well the standard mean-variance model and two reinforcement models predict people's portfolio decisions. The basic reinforcement model predicts a learning process that relies solely on the portfolio's overall return, whereas the proposed extended reinforcement model also takes the risk and covariance of the investments into account. The experimental results illustrate that people reacted sensitively to...

    and objectives We have evaluated the training capacity of the Spanish resident training book as an electronic portfolio to achieve the learning objectives of otorhinolaryngology (ENT) residents. A multi-method qualitative investigation with transversal characteristics, temporal and retrospective guidance was performed on Spanish ENT residents using a structured questionnaire, a semi-structured interview, and a computer application on the FORMIR website. A 56.5% of ENT-residents specialising in one of the 63 accredited Spanish hospitals between 2009-2012 participated in the study. The results obtained show that the ENT residents who used the e-portfolio were better able to implement self-guided study, were more aware of their learning objectives, fulfilled the training programme more efficiently, identified the causes of learning gaps more clearly, and considered FORMIR in e-portfolio format to be an ideal training tool to replace the resident training book in paper format. The ENT residents greatly appreciated the training benefits of FORMIR as an e-portfolio, especially its simple and intuitive interface, the ease and comfort with which they could record their activities, the automatic and numeric feedback on the acquisition of their competencies (which facilitates self-guided learning), its storage capacity for evidence, and its ability to be used as UEMS logbook as well as a standard curriculum vitae. All these features make FORMIR a training and evaluation tool that outperforms similar instruments available to ENT residents. They do not hesitate to identify it as the ideal resident training book for facilitating their specialised training.

    Full Text Available Purpose: The Catalonian Government has the intention of introducing the digital portfolio before 2017, an initiative related to new approaches for learning. Taking in consideration the increasing interest for digital portfolio as a new communication channel for education, the article aims are: on the one hand to describe how the digital portfolio works and on the other hand, to identify a list of criteria that should be useful for educative centers to select the best application to create the digital portfolio according to their needs.Design/methodology/approach: Firstly, a theoretical framework for portfolio functioning is described. After, applications to support the digital portfolio are classified. Next, a requirement analysis on an ideal application to support the portfolio is made, according to those phases for the portfolio creation identified in the theoretical framework. Lastly, a list of criteria is established to select the application for creating the digital portfolio.Findings and Originality/value: The article contributes to structure the portfolio creation process in some stages and phases in a wider way that it is described in the literature. In addition, a list of criteria is defined to help educative centers to select the application for managing the portfolio that fits better with their objectives. These criteria have been obtained with an exhaustive methodology.Research limitations/implications: In order to put in practice the identified criteria it is proposed to complete the multi-criteria decision model in a new study. It should include processes to weigh criteria and define normalizations. Afterwards it would be able to analyze the value of the model studying the satisfaction for using it by a sample of educative centers.Practical implications: The list of criteria identified should facilitate the selection of the more adequate application to create the learning portfolio to the educative centers, according to their

    2015-12-01

    Health education is the teaching by healthcare professionals of healthcare-related knowledge and skills to students in order that these students learn to help patients self-manage their disease and maintain health. This article introduces a new strategy in health education known as the learning portfolio and presents the theoretical basis and function of the learning portfolio and the current application of this approach in academic and health education. The learning portfolio is a learner-centric approach that collects evidence related to an individual's learning process systematically. This approach helps educators understand learner needs and conditions, while allowing the learner to observe his / her learning process in a manner that promotes self-reflection, continual inspection, and behavioral modification throughout the learning process. The results enhance the motivation of learners and strengthen their care confidence in accomplishing learning tasks.

    2016-01-01

    The research on service supply chain has attracted more and more focus from both academia and industrial community. In a service supply chain, the selection of supplier portfolio is an important and difficult problem due to the fact that a supplier portfolio may include multiple suppliers from a variety of fields. To address this problem, we propose a novel supplier portfolio selection method based on a well known machine learning approach, i.e., Ranking Neural Network (RankNet). In the proposed method, we regard the problem of supplier portfolio selection as a ranking problem, which integrates a large scale of decision making features into a ranking neural network. Extensive simulation experiments are conducted, which demonstrate the feasibility and effectiveness of the proposed method. The proposed supplier portfolio selection model can be applied in a real corporation easily in the future.

    Full Text Available In learning environment, portfolio is used as a tool to keep track of learner’s progress. Particularly, when it comes to e-learning, continuous assessment allows greater customization and efficiency in learning process and prevents students lost interest in their study. Also, each student has his own characteristics and learning skills that must be taken into account in order to keep learner`s interest. So, personalized monitoring is the key to guarantee the success of technology-based education. In this context, portfolio assessment emerge as the solution because is an easy way to allow teacher organize and personalize assessment according to students characteristic and need. A portfolio assessment can contain various types of assessment like formative assessment, summative assessment, hetero or self-assessment and use different instruments like multiple choice questions, conceptual maps, and essay among others. So, a portfolio assessment represents a compilation of all assessments must be solved by a student in a course, it documents progress and set targets. In previous work, it has been proposed a conceptual framework that consist of an ontology network named AOnet which is a semantic tool conceptualizing different types of assessments. Continuing that work, this paper presents a proposal to implement portfolios assessment in e-learning environments. The proposal consists of a semantic model that describes key components and relations of this domain to set the bases to develop a tool to generate, manage and perform portfolios assessment.

    The residency training experience is the perfect environment for learning. The university/institution patient population provides a never-ending supply of patients with unique management challenges. Resources abound that allow the discovery of knowledge about similar situations. Senior teachers provide counseling and help direct appropriate care. Periodic testing and evaluations identify deficiencies, which can be corrected with future study. What happens, however, when the resident graduates? Do they possess all the knowledge they'll need for the rest of their career? Will medical discovery stand still limiting the need for future study? If initial certification establishes that the physician has the skills and knowledge to function as an independent physician and surgeon, how do we assure the public that plastic surgeons will practice lifelong learning and remain safe throughout their career? Enter Maintenance of Certification (MOC). In an ideal world, MOC would provide many of the same tools as residency training: identification of gaps in knowledge, resources to correct those deficiencies, overall assessment of knowledge, feedback about communication skills and professionalism, and methods to evaluate and improve one's practice. This article discusses the need; for education and self-assessment that extends beyond residency training and a commitment to lifelong learning. The American Board of Plastic Surgery MOC program is described to demonstrate how it helps the diplomate reach the goal of continuous practice improvement.

    Full Text Available The present study sought to investigate the effect of portfolio assessment on idiom competence of Iranian EFL learners. For the purpose of this study, 30 students from upper-intermediate level of English proficiency took part in this study. They were chosen through convenience sampling from a language institute in Rasht, Iran. They were randomly divided into experimental and control groups. A TOEFL test and a test of idioms were given to the students to ensure their homogeneity in terms of language proficiency and knowledge of idioms, respectively. The experimental group was intended to create a portfolio and put their writing samples, in which idioms were used, in the portfolio. They were involved in the process of self-and-peer assessment. The teacher also provided them with feedback and comments. However, the control group received a kind of traditional instruction. In other words, the control group used the idioms in their writing without receiving any comments and delivered it to their teacher to be scored. The treatment lasted for 10 sessions and a post-test was administered in the end. Independent samples t-tests were used to analyze the data gathered from the pretests and the posttest. The findings indicated that there was a statistically significant difference between the two groups in terms of idioms and portfolio was found to be able to improve students’ knowledge of idioms. The results of this study have some implications for teaching and learning idioms.

  14. Using E-Learning Portfolio Technology To Support Visual Art Learning

    Directory of Open Access Journals (Sweden)

    Greer Jones-Woodham

    2009-08-01

    Full Text Available Inspired by self-directed learning (SDL theories, this paper uses learning portfolios as a reflective practice to improve student learning and develop personal responsibility, growth and autonomy in learning in a Visual Arts course. Students use PowerPoint presentations to demonstrate their concepts by creating folders that are linked to e-portfolios on the University website. This paper establishes the role of learning e-portfolios to improve teaching and learning as a model of reflection, collaboration and documentation in the making of art as a self-directed process. These portfolios link students' creative thinking to their conceptual frameworks. They also establish a process of inquiry using journals to map students' processes through their reflections and peer feedback. This practice argues that learning e-portfolios in studio art not only depends on a set of objectives whose means are justified by an agreed end but also depends on a practice that engages students' reflection about their actions while in their art- making practice. Using the principles of the maker as the intuitive and reflective practitioner, the making as the process in which the learning e-portfolios communicate the process and conceptual frameworks of learning and the eventual product, and the made as evidence of that learning in light of progress made, this paper demonstrates that learning-in-action and reflecting-in and-on-action are driven by self-direction. With technology, students bring their learning context to bear with the use of SDL. Students' use of PowerPoint program technology in making their portfolios is systematic and builds on students' competencies as this process guides students' beliefs and actions about their work that is based on theory and concepts in response to a visual culture that is Trinidad and Tobago. Students' self–directed art-making process as a self directed learning, models the process of articulated learning. Communicating about

  6. Do portfolios have a future?

    Science.gov (United States)

    Driessen, Erik

    2017-03-01

    While portfolios have seen an unprecedented surge in popularity, they have also become the subject of controversy: learners often perceive little gain from writing reflections as part of their portfolios; scholars question the ethics of such obligatory reflection; and students, residents, teachers and scholars alike condemn the bureaucracy surrounding portfolio implementation in competency-based education. It could be argued that mass adoption without careful attention to purpose and format may well jeopardize portfolios' viability in health sciences education. This paper explores this proposition by addressing the following three main questions: (1) Why do portfolios meet with such resistance from students and teachers, while educators love them?; (2) Is it ethical to require students to reflect and then grade their reflections?; (3) Does competency-based education empower or hamper the learner during workplace-based learning? Twenty-five years of portfolio reveal a clear story: without mentoring, portfolios have no future and are nothing short of bureaucratic hurdles in our competency-based education programs. Moreover, comprehensive portfolios, which are integrated into the curriculum and much more diverse in content than reflective portfolios, can serve as meaningful patient charts, providing doctor and patient with useful information to discuss well-being and treatment. In this sense, portfolios are also learner charts that comprehensively document progress in a learning trajectory which is lubricated by meaningful dialogue between learner and mentor in a trusting relationship to foster learning. If we are able to make such comprehensive and meaningful use of portfolios, then, yes, portfolios do have a bright future in medical education.

    Full Text Available The purpose of this research paper is to examine the use of portfolios in the teaching and learning of physics at a Singapore private college. The paper starts with a short introduction of the types of students and the purpose of using academic portfolios in their learning and assessment. Some ideas of how portfolios can be used in the local context will also be discussed. It is necessary for teachers to know how to incorporate portfolio assessment in their daily lesson plans. At the same time, students who are studying physics at the college should also know how to use portfolios to their academic advantage. The paper also highlights three of the relevant work artifacts that can be included into the physics portfolios. The three work samples are concept-maps, internet research reports and newspaper articles reports. Concept-maps are useful tools to help students establish the connections between concepts. Internet research reports serve as important means for students to know more about how some scientific devices or technology use physics in the operations. Newspaper articles reports allow students to understand the real impact of physics on the lives of people. Subsequent sections of the paper discuss about the organizational flow of the portfolio, the timeline, the selection process, the portfolio checklist and assessment rubrics, the positive influences of using portfolios, the issues to consider and also the potential problems that physics teachers may face in implementing portfolios. These sections present the important framework which teachers can use as references for their portfolio initiatives in schools.

    Adoption of portfolio assessment in the educational environment is gaining attention as a means to incorporate self-assessment into the curriculum and to use evidence to support learning outcomes and to demonstrate competency. Portfolios provide a medium for students to demonstrate and document their personal and professional growth across the curriculum. The purpose of this literature review is to discuss the drivers for portfolio education, the benefits to both students and program faculty/administrators, the barriers associated with portfolio use, and suggested solutions that have been determined through several years of "lessons learned." The University of Missouri Kansas City School of Dentistry, Division of Dental Hygiene department has been utilizing portfolio assessment for over 15 years and has collected data related to portfolio performance since 2001. Results from correlational statistics calculated on the 312 dental hygiene students that graduated from 2001 to 2013 demonstrate a positive and significant relationship between portfolio performance and overall GPA as well as portfolio performance and NBDHE scores.

    2011-03-01

    For healthcare professionals, the educational portfolio is the most widely used component of lifelong learning - a vital aspect of modern medical practice. When used effectively, portfolios provide evidence of continuous learning and promote reflective practice. But traditional portfolio models are in danger of becoming outmoded, in the face of changing expectations of healthcare provider competences today. Portfolios in health care have generally focused on competencies in clinical skills. However, many other domains of professional development, such as professionalism and leadership skills, are increasingly important for doctors and health care professionals, and must be addressed in amassing evidence for training and revalidation. There is a need for modern health care learning portfolios to reflect this sea change. A new model for categorising the health care portfolios of professionals is proposed. The ECLIPPx model is based on personal practice, and divides the evidence of ongoing professional learning into four categories: educational development; clinical practice; leadership, innovation and professionalism; and personal experience. The ECLIPPx model offers a new approach for personal reflection and longitudinal learning, one that gives flexibility to the user whilst simultaneously encompassing the many relatively new areas of competence and expertise that are now required of a modern doctor. © Blackwell Publishing Ltd 2011.

  12. Learning style preferences of surgical residency applicants.

    2015-09-01

    The learning style preferences of general surgery residents have been previously reported; there is evidence that residents who prefer read/write learning styles perform better on the American Board of Surgery In-Training Examination (ABSITE). However, little is known regarding the learning style preferences of applicants to general surgery residency and their impact on educational outcomes. In this study, the preferred learning styles of surgical residency applicants were determined. We hypothesized that applicant rank data are associated with specific learning style preferences. The Fleming VARK learning styles inventory was offered to all general surgery residency applicants that were interviewed at a university hospital-based program. The VARK model categorizes learners as visual (V), aural (A), read/write (R), kinesthetic (K), or multimodal (MM). Responses on the inventory were scored to determine the preferred learning style for each applicant. Applicant data, including United States Medical Licensing Examination (USMLE) scores, class rank, interview score, and overall final applicant ranking, were examined for association with preferred learning styles. Sixty-seven applicants were interviewed. Five applicants were excluded due to not completing the VARK inventory or having incomplete applicant data. The remaining 62 applicants (92%) were included for analysis. Most applicants (57%) had a multimodal preference. Sixty-nine percent of all applicants had some degree of preference for kinesthetic learning. There were statistically significant differences between applicants of different learning styles in terms of USMLE step 1 scores (P = 0.001) and USMLE step 2 clinical knowledge scores (P = 0.01), but not for class ranks (P = 0.27), interview scores (P = 0.20), or final ranks (P = 0.14). Multiple comparison analysis demonstrated that applicants with aural preferences had higher USMLE 1 scores (233.2) than those with kinesthetic (211.8, P = 0.005) or multimodal

  13. Learning through a portfolio of carbon capture and storage demonstration projects

    2016-01-01

    Carbon dioxide capture and storage (CCS) technology is considered by many to be an essential route to meet climate mitigation targets in the power and industrial sectors. Deploying CCS technologies globally will first require a portfolio of large-scale demonstration projects. These first projects should assist learning by diversity, learning by replication, de-risking the technologies and developing viable business models. From 2005 to 2009, optimism about the pace of CCS rollout led to mutually independent efforts in the European Union, North America and Australia to assemble portfolios of projects. Since 2009, only a few of these many project proposals remain viable, but the initial rationales for demonstration have not been revisited in the face of changing circumstances. Here I argue that learning is now both more difficult and more important given the slow pace of deployment. Developing a more coordinated global portfolio will facilitate learning across projects and may determine whether CCS ever emerges from the demonstration phase.

  14. Building a Smart E-Portfolio Platform for Optimal E-Learning Objects Acquisition

    2013-01-01

    Full Text Available In modern education, an e-portfolio platform helps students in acquiring e-learning objects in a learning activity. Quality is an important consideration in evaluating the desirable e-learning object. Finding a means of determining a high quality e-learning object from a large number of candidate e-learning objects is an important requirement. To assist student learning in a modern e-portfolio platform, this work proposed an optimal selection approach determining a reasonable e-learning object from various candidate e-learning objects. An optimal selection approach which uses advanced information techniques is proposed. Each e-learning object undergoes a formalization process. An Information Retrieval (IR technique extracts and analyses key concepts from the student’s previous learning contexts. A context-based utility model computes the expected utility values of various e-learning objects based on the extracted key concepts. The expected utility values of e-learning objects are used in a multicriteria decision analysis to determine the optimal selection order of the candidate e-learning objects. The main contribution of this work is the demonstration of an effective e-learning object selection method which is easy to implement within an e-portfolio platform and which makes it smarter.

    Motivation is an internal mood that moves individuals to act, points them in certain directions, and maintains them in activities, playing a very important role in self-regulated learning and academic performance. Our objective was to evaluate motivation and self-regulation of knowledge in pediatric residents in a third-level hospital, and to determine if there are differences according to the type of specialty and sociodemographic variables. All residents who agreed to participate responded to the Motivated Strategies for Learning Questionnaire. Cronbach alpha was performed to determine reliability. The mean value of each subscale was compared with Student's t test or ANOVA, correlation of subscales with Pearson test. A value of p≤0.05 was considered significant. We included 118 residents. The questionnaire was highly reliable (α=0.939). There were no significant differences in motivation or learning strategies according to sex, marital status, or age. Those residents studying a second or third specialization had significantly higher scores in elaboration, critical thinking, and peer learning. There were significant correlations between intrinsic motivation and self-efficacy with the development of knowledge strategies such as elaboration, critical thinking, and metacognitive self-regulation. Our students present average-to-high scores of motivation and knowledge strategies, with a significant difference according to type of specialization. There is a high correlation between motivation and knowledge strategies.

    The tendency to use portfolios for evaluation has been developed with the aim of optimizing the culture of assessment. The present study was carried out to determine the effect of using portfolios as an evaluation method on midwifery students' learning and satisfaction in prenatal practical training. In this prospective cohort study, all midwifery students in semester four (n=40), were randomly allocated to portfolio and routine evaluation groups. Based on their educational goals, the portfolio groups prepared packages which consisted of a complete report of the history, physical examinations, and methods of patient management (as evaluated by a checklist) for women who visited a prenatal clinic. During the last day of their course, a posttest, clinical exam, and student satisfaction form were completed. The two groups' mean age, mean pretest scores, and their prerequisite course that they should have taken in the previous semester were similar. The mean difference in the pre and post test scores for the two groups' knowledge and comprehension levels did not differ significantly (P>0.05). The average scores on questions in Bloom's taxonomy 2 and 3 of the portfolio group were significantly greater than those of the routine evaluation group (P=0.002, P=0.03, respectively). The mean of the two groups' clinical exam scores was significantly different. The portfolio group's mean scores on generating diagnostic and therapeutic solutions and the ability to apply theory in practice were higher than those of the routine group. Overall, students' satisfaction scores in the two evaluation methods were relatively similar. Portfolio evaluation provides the opportunity for more learning by increasing the student's participation in the learning process and helping them to apply theory in practice.

    Background Electronic evaluation portfolios may play a role in learning and evaluation in clinical settings and may complement other traditional evaluation methods (bedside evaluations, written exams and tutor-led evaluations). Methods 133 third-year medical students used the McGill Electronic Evaluation Portfolio (MEEP) during their one-month clerkship rotation in Geriatric Medicine between September 2002 and September 2003. Students were divided into two groups, one who received an introductory hands-on session about the electronic evaluation portfolio and one who did not. Students' marks in their portfolios were compared between both groups. Additionally, students self-evaluated their performance and received feedback using the electronic portfolio during their mandatory clerkship rotation. Students were surveyed immediately after the rotation and at the end of the clerkship year. Tutors' opinions about this method were surveyed once. Finally, the number of evaluations/month was quantified. In all surveys, Likert scales were used and were analyzed using Chi-square tests and t-tests to assess significant differences in the responses from surveyed subjects. Results The introductory session had a significant effect on students' portfolio marks as well as on their comfort using the system. Both tutors and students reported positive notions about the method. Remarkably, an average (± SD) of 520 (± 70) evaluations/month was recorded with 30 (± 5) evaluations per student/month. Conclusion The MEEP showed a significant and positive effect on both students' self-evaluations and tutors' evaluations involving an important amount of self-reflection and feedback which may complement the more traditional evaluation methods.

    Full Text Available The purpose of this research paper is to examine the use of portfolios in the teaching and learning of physics at a Singapore private college. The paper starts with a short introduction of the types of students and the purpose of using academic portfolios in their learning and assessment. Some ideas of how portfolios can be used in the local context will also be discussed. It is necessary for teachers to know how to incorporate portfolio assessment in their daily lesson plans. At the same time, students who are studying physics at the college should also know how to use portfolios to their academic advantage. The paper also highlights three of the relevant work artifacts that can be included into the physics portfolios. The three work samples are concept-maps, internet research reports and newspaper articles reports. Concept-maps are useful tools to help students establish the connections between concepts. Internet research reports serve as important means for students to know more about how some scientific devices or technology use physics in the operations. Newspaper articles reports allow students to understand the real impact of physics on the lives of people. Subsequent sections of the paper discuss about the organizational flow of the portfolio, the timeline, the selection process, the portfolio checklist and assessment rubrics, the positive influences of using portfolios, the issues to consider and also the potential problems that physics teachers may face in implementing portfolios. These sections present the important framework which teachers can use as references for their portfolio initiatives in schools.

    The current cost disadvantage of photovoltaics (PV) risks to reduce its relevance in climate policy strategies. Depending on the used assumptions, electricity from PV can become competitive between 2015 and 2040. Cost competitiveness is, however, a conditional criterion and as an alternative to the learning curve perspective, the future role of PV in electricity production is assessed from a portfolio theory or Capital Asset Pricing Model perspective. In this analysis, the focus is on the input price risks. Fossil fuel price volatility can strongly reduce the financial return of conventional generating technologies. From a welfare perspective, energy planners should try to minimise this risk by adding risk-neutral or no-risk technologies to their portfolio. With an analysis for the year 2025, we illustrate how the addition of renewable capacity to an existing portfolio can lower total portfolio risk without a significant reduction of profitability. PV then emerges as an attractive technology, especially once the best locations for wind energy are already developed

    This article seeks to analyze the experience of collective construction of portfolios as a teaching-learning method in the discipline of Health Policy, identifying the competencies developed by students. Qualitative research, whose collection and data processing were conducted by means of documental and thematic analysis of 34 portfolios. The "Learning to be" and "Learning to live and work together" competencies were considered according to the proposals of the UNESCO report for Education. The training of critical-reflexive individuals, provided by the portfolio, was particularly observed when students reported the transformation of the negative views that they had about the health care system - an inefficient and precarious policy - to a positive vision - policy which deals with the principles of equity, integrity and universality. This process of critical transformation is the result of the practice and use of communication skills, information management (search, selection, analysis and evaluation of information), leadership, cooperation and human relationships (teamwork, ethics and recognition of diversity), and personal competencies (time management, responsibility and planning), namely important skills in the training of professionals committed to the national health policy.

    Residents may view feedback from patients and their families with greater skepticism than feedback from supervisors and peers. While discussing patient and family feedback with faculty may improve residents' acceptance of feedback and learning, specific strategies have not been identified. We explored pediatrics residents' perspectives of patient feedback and identified strategies that promote residents' reflection on and learning from feedback. In this multi-institutional, qualitative study conducted in June and July 2016, we conducted focus groups with a purposive sample of pediatrics residents after their participation in a randomized controlled trial in which they received written patient feedback and either discussed it with faculty or reviewed it independently. Focus group transcripts were audiorecorded, transcribed, and analyzed for themes using the constant comparative approach associated with grounded theory. Thirty-six of 92 (39%) residents participated in 7 focus groups. Four themes emerged: (1) residents valued patient feedback but felt it may lack the specificity they desire; (2) discussing feedback with a trusted faculty member was helpful for self-reflection; (3) residents identified 5 strategies faculty used to facilitate their openness to and acceptance of patient feedback (eg, help resident overcome emotional responses to feedback and situate feedback in the context of lifelong learning); and (4) residents' perceptions of feedback credibility improved when faculty observed patient encounters and solicited feedback on the resident's behalf prior to discussions. Discussing patient feedback with faculty provided important scaffolding to enhance residents' openness to and reflection on patient feedback.

    Full Text Available In recent years, the development of information and communication technology (ICT in the world and Malaysia namely has created a significant impact on the methods of communicating information and knowledge to the learners and consequently, innovative teaching techniques have evolved to change the ways teachers teach and the ways students learn. This study main focuses are directed on developing a cooperative learning environment to promote an active learning environment of smart schools in Malaysia. Within this learning process, multimedia technology and Web 2.0 tools, namely, MyPortfolio were integrated to provide the students to learn on their own as well as to document their progress and experience within this cooperative learning environment. The core purpose of this study is to establish the impact on student learning, their perceptions and learning experiences of the cooperative learning environment using web 2.0 tools among the smart secondary schools students in Malaysia. Surveys were conducted to students to ascertain their reaction towards these learning environment activities. The results of this project were encouraging as the students managed to cope with each other to reach their common goal. The usage of blogs acts as an important tool to enhance team cooperation and to foster a learning community within the class.

    Using the frameworks of transformational learning and situated learning theory, we developed a technology-enhanced professionalism curricular model to build a learning community aimed at promoting residents' self-reflection and self-awareness. The RAPR model had 4 components: (1) R ecognize : elicit awareness; (2) A ppreciate : question assumptions and take multiple perspectives; (3) P ractice : try new/changed perspectives; and (4) R eflect : articulate implications of transformed views on future actions. The authors explored the acceptability and practicality of the RAPR model in teaching professionalism in a residency setting, including how residents and faculty perceive the model, how well residents carry out the curricular activities, and whether these activities support transformational learning. A convenience sample of 52 postgraduate years 1 through 3 internal medicine residents participated in the 10-hour curriculum over 4 weeks. A constructivist approach guided the thematic analysis of residents' written reflections, which were a required curricular task. A total of 94% (49 of 52) of residents participated in 2 implementation periods (January and March 2015). Findings suggested that RAPR has the potential to foster professionalism transformation in 3 domains: (1) attitudinal, with participants reporting they viewed professionalism in a more positive light and felt more empathetic toward patients; (2) behavioral, with residents indicating their ability to listen to patients increased; and (3) cognitive, with residents indicating the discussions improved their ability to reflect, and this helped them create meaning from experiences. Our findings suggest that RAPR offers an acceptable and practical strategy to teach professionalism to residents.

    The program summary of the American Board of Surgery In-Service Training Exam (ABSITE) can be used to quantitate cognitive learning during a surgical residency and to identify areas of curricular weakness in a residency program. Knowledge on each question is categorized as high (known) or low (unknown) depending on the percentage of residents who answered correctly. Knowledge of Level 1 (entry) residents is then compared with Level 5 (exit) residents. Each ABSITE question can thus be categorized on entry versus exit as known-known, unknown-unknown, unknown-known, and known-unknown. Only about half of unknown knowledge on entry appears to become known on exit. Very little knowledge known on entry becomes unknown on exit. Weaknesses in specific subject areas can be readily identified by ranking questions according to the number of exiting residents who answer incorrectly. Use of this technique to quantitate cognitive learning in a residency program may allow objective assessment of changes in curriculum.

    The Portfolio is an assessment tool of learning that recently appears in academic forums, and since 2008 is part of the University Teacher Education Program (Teaching Training) at University Institute of Hospital Italiano. Was included to allow teachers reflect on their own practices and accompany them in their educational work everyday. This paper shares the evaluative experience focused on the educational value of the writing process of the Portfolio, as long as is a reflection and a learning tool, by the relationship that promotes between theory and practice. Writing promotes psychological processes that enable students gain new meanings of the knowledge and take over them. At the same time, it can attend the construction of practical rationality that governs the ways of intervening in the classroom, because they write and reflect from their own teaching work. They have been introduced changes in the proposed during the course of its implementation to preserve its purposes: to accompany the draft review, jointly define index, etc. Students point that it is high impact training and conclude that writing is re-think about what they have learned, and therefore keep learning.

    The operating room (OR) remains the main teaching venue for surgical trainees. The OR is considered a pure-discovery learning environment; the downsides of this can be putatively overcome when faculty and trainee arrive at a shared understanding of learning. This study aimed to better understand preoperative learning goals to identify areas of commonalities and potential barrier to intraoperative teaching. Brief, structured preoperative interviews were conducted outside the OR with the resident and faculty member who were scheduled to operate together. Answers were analyzed and grouped using grounded theory. Twenty-seven resident-faculty pairs were interviewed. Nine residents (33.3%) were junior (PGY 1 and 2) and 18 (66.7%) were senior (PGY 3 through 5). Learning goal categories that emerged from the response analysis were anatomy, basic and advanced surgical skills, general and specific procedural tasks, technical autonomy, and pre-, intra-, and postoperative considerations. Residents articulated fewer learning goals than faculty (1.5 versus 2.4; P = 0.024). The most frequently identified learning goal by both groups was one classifiable under general procedural tasks; the greatest divergence was seen regarding perioperative considerations, which were identified frequently by faculty members but rarely by residents. Faculty articulate significantly more learning goals for the residents they will operate with than residents articulate for themselves. Our data suggest that residents and faculty align on some learning goals for the OR but residents tend to be more limited, focusing predominantly on technical aspects of the operation. Faculty members tend to hold a broader view of the learning potential of the OR. These discrepancies may present barriers to effective intraoperative teaching. Copyright © 2011 Elsevier Inc.

    Effects of residents' blended learning on their clinical performance have rarely been reported. A blended learning pilot program was instituted at Southern Illinois University School of Medicine's Obstetrics and Gynecology program. One of the modules was chronic hypertension in pregnancy. We sought to evaluate if the resident blended learning was transferred to their clinical performance six months after the module. A review of patient charts demonstrated inadequate documentation of history, evaluation, and counseling of patients with chronic hypertension at the first prenatal visit by Obstetrics and Gynecology (OB/GYN) residents. A blended learning module on chronic hypertension in pregnancy was then provided to the residents. A retrospective chart review was then performed to assess behavioral changes in the OB/GYN residents. This intervention was carried out at the Department of Obstetrics and Gynecology, Southern Illinois University. All 16 OB/GYN residents were enrolled in this module as part of their educational curriculum. A query of all prenatal patients diagnosed with chronic hypertension presenting to the OB/GYN resident clinics four months prior to the implementation of the blended learning module (March 2015-June 2015) and six months after (July 20, 2015-February 2016) was performed. Data were collected from outpatient charts utilizing the electronic medical record. Data were abstracted from resident documentation at the first prenatal visit. The residents thought that the blended learning module was applicable to performance improvement in the real-world setting. Patients evaluated before ( n = 10) and after ( n = 7) the intervention were compared. After the intervention, there was an increase in assessment of baseline liver enzymes, referral for electrocardiogram, and early assessment for diabetes in the obese patients. More patients were provided a blood pressure cuff after the module (71.4% vs. 20%). Data were provided to the residents in an

    Although burnout is viewed as a syndrome rooted in the working environment and organizational culture, the role of the learning environment in the development of resident burnout remains unclear. We aimed to evaluate the association between burnout and the learning environment in a cohort of Belgian residents. We conducted a cross-sectional online survey among residents in a large university hospital in Belgium. We used the Dutch version of the Maslach Burnout Inventory (UBOS-C) to assess burnout and the Dutch Residency Educational Climate Test (D-RECT) to assess the learning environment. A total of 236 residents (29 specialties) completed the survey (response rate 34.6%), of which 98 (41.5%) met standard criteria for burnout. After multivariate regression analysis adjusting for hours worked per week, quality of life and satisfaction with work-life balance, we found an inverse association between D-RECT scores and the risk of burnout (adjusted odds ratio; 0.47 for each point increase in D-RECT score; 95% CI, 0.23 - 0.95; p = 0.01). Resident burnout is highly prevalent in our cohort of Belgian residents. Our results suggest that the learning environment plays an important role in reducing the risk of burnout among residents.

    Educating Doctor of Nursing Practice (DNP) students for an increasingly complex health care environment requires novel applications of learning concepts and technology. A deliberate and thoughtful process is required to integrate concepts of the DNP program into practice paradigm changes to subsequently improve students' abilities to innovate solutions to complex practice problems. The authors constructed or participated in electronic portfolio development inspired by theories of metacognition and integrated learning. The objective was to develop DNP student's reflection, integration of concepts, and technological capabilities to foster the deliberative competencies related to the DNP Essentials and the foundations of the DNP program. The pedagogical process demonstrates how e-portfolios adapted into the doctoral-level curriculum for DNP students can address the Essentials and foster the development of metacognitive capabilities, which translates into practice changes. The authors suggest that this pedagogical approach has the potential to optimize reflective and deliberative competencies among DNP students. [J Nurs Educ. 2017;56(8):497-500.].

    To examine the relationship between lifelong learning (LLL) and academic motivation for residents in a psychiatry residency program, trainee factors that influence LLL, and psychiatry residents' LLL practices. Between December 2014 and February 2015, 105 of 173 (61%) eligible psychiatry residents from the Department of Psychiatry, University of Toronto, completed a questionnaire with three study instruments: an LLL needs assessment survey, the Jefferson Scale of Physician Lifelong Learning (JeffSPLL), and the Academic Motivation Scale (AMS). The AMS included a relative autonomy motivation score (AMS-RAM) measuring the overall level of intrinsic motivation (IM). A significant correlation was observed between JeffSPLL and AMS-RAM scores (r = 0.39, P motivation identification domain (mean difference [M] = 0.38; 95% confidence interval [CI] [0.01, 0.75]; P = .045; d = 0.44) compared with senior residents. Clinician scientist stream (CSS) residents had significantly higher JeffSPLL scores compared with non-CSS residents (M = 3.15; 95% CI [0.52, 5.78]; P = .020; d = 0.57). The use of rigorous measures to study LLL and academic motivation confirmed prior research documenting the positive association between IM and LLL. The results suggest that postgraduate curricula aimed at enhancing IM, for example, through support for learning autonomously, could be beneficial to cultivating LLL in learners.

    With the rapid development of technology in medical education, orthopaedic educators are recognizing that the way residents learn and access information is profoundly changing. Residency programs are faced with the challenging problem that current educational methods are not designed to take full advantage of the information explosion and rapid technologic changes. This disconnection is often seen in the potentially separate approaches to education preferred by residents and orthopaedic educators. Becoming connected with residents requires understanding the possible learning technologies available and the learners' abilities, needs, and expectations. It is often assumed that approaches to strategic lifelong learning are developed by residents during their training; however, without the incorporation of technology into the learning environment, residents will not be taught the digital literacy and information management strategies that will be needed in the future. To improve learning, it is important to highlight and discuss current technologic trends in education, the possible technologic disconnection between educators and learners, the types of learning technologies available, and the potential opportunities for getting connected.

    The Accreditation Council for Graduate Medical Education instituted the 80-h workweek for residency programs in 2003. This presented a unique challenge for surgery residents who must acquire a medical and technical knowledge base during training. Therefore, learning should be delivered in an environment congruent with an individual's learning style. In this study, we evaluated the learning styles of general surgery residents to determine how learning styles changed after the implementation to the 80-h workweek. Kolb learning style inventory was taken by general surgery residents at the University of Cincinnati's Department of Surgery, and results from 1999-2012 were analyzed. Statistical analysis was performed using the chi-squared, logistic regression and Wilcoxon rank-sum test. Significance was defined as a P value of learning styles after the institution of the 80-h workweek to converging (43.9%) and accommodating (40.4%, P learning. This change paralleled the transition to a more team-based approach to patient care with the implementation of the 80-h workweek. These findings are important for surgical educators to consider in the development of surgical resident curriculum. Copyright © 2016 Elsevier Inc. All rights reserved.

    2011-02-01

    This paper analyses the use of an e-portfolio system in contributing to the personalized learning of two dyslexic learners at the University of Wolverhampton, UK. The rationale for this research rests at the intersection of generic findings from e-portfolio (and wider e-learning) research and the still challenging project in higher education (HE) of creating inclusive curricula. A qualitative, ethnographic approach was employed in a piece of collaborative research between academic staff and dyslexic learners. Two retrospective learner narratives were constructed and then reviewed by all co-authors in terms of the 'personalized fit' which they allowed with dyslexic thinking, learning and writing experience. The findings suggest a potential refinement of the general pedagogical claims about e-portfolio-based learning when considering dyslexic learners and thence the value of an enhanced prioritization of e-portfolio learning practices within inclusive HE curricula. The review and analysis also allow a 'critical' discussion of the practical and theoretical issues arising within this work. Copyright © 2010 John Wiley & Sons, Ltd.

    Within the 52 health districts in South Africa, the family physician is seen as the clinical leader within a multi-professional district health team. Family physicians must be competent to meet 90% of the health needs of the communities in their districts. The eight university departments of Family Medicine have identified five unit standards, broken down into 85 training outcomes, for postgraduate training. The family medicine registrar must prove at the end of training that all the required training outcomes have been attained. District health managers must be assured that the family physician is competent to deliver the expected service. The Colleges of Medicine of South Africa (CMSA) require a portfolio to be submitted as part of the uniform assessment of all registrars applying to write the national fellowship examinations. This study aimed to achieve a consensus on the contents and principles of the first national portfolio for use in family medicine training in South Africa. A workshop held at the WONCA Africa Regional Conference in 2009 explored the purpose and broad contents of the portfolio. The 85 training outcomes, ideas from the WONCA workshop, the literature, and existing portfolios in the various universities were used to develop a questionnaire that was tested for content validity by a panel of 31 experts in family medicine in South Africa, via the Delphi technique in four rounds. Eighty five content items (national learning outcomes) and 27 principles were tested. Consensus was defined as 70% agreement. For those items that the panel thought should be included, they were also asked how to provide evidence for the specific item in the portfolio, and how to assess that evidence. Consensus was reached on 61 of the 85 national learning outcomes. The panel recommended that 50 be assessed by the portfolio and 11 should not be. No consensus could be reached on the remaining 24 outcomes and these were also omitted from the portfolio. The panel recommended

    The study is designed to evaluate the effectiveness of an active form of resident instruction, cooperative learning, and the residents' response to that form of instruction. The residents dictated three sets of reports both before and after instruction in radiology reporting using the cooperative learning method. The reports were evaluated for word count, Flesch-Kincaid grade level, advancement on clinical spectrum, clarity, and comparison to prior reports. The reports were evaluated for changes in performance characteristics between the pre- and postinstruction dictations. The residents' response to this form of instruction was evaluated by means of a questionnaire. The instruction was effective in changing the resident dictations. The results became shorter (Pcooperative learning activities. The least positive responses related to the amount of time devoted to the project. Sixty-three percent of respondents stated that the time devoted to the project was appropriate. Cooperative learning can be an effective tool in the setting of the radiology residency.

    As a consequence of surgical resident duty hour restrictions, there is a need for faculty to utilize novel teaching methods to convey information in a more efficient manner. The current paradigm of surgical training, which has not changed significantly since the time of Halsted, assumes that all residents assimilate information in a similar fashion. However, recent data has shown that learners have preferences for the ways in which they receive and process information. The VARK model categorizes learners as visual (V), aural (A), read/write (R), and kinesthetic (K). The VARK learning style preferences of surgical residents have not been previously evaluated. In this study, the preferred learning styles of general surgery residents were determined, along with faculty and resident perception of resident learning styles. In addition, we hypothesized that American Board of Surgery In-Training Exam (ABSITE) scores are associated with preference for a read/write (R) learning style. The Fleming VARK learning styles inventory was administered to all general surgery residents at a university hospital-based program. Responses on the inventory were scored to determine the preferred learning style for each resident. Faculty members were surveyed to determine their accuracy in identifying the preferred learning style of each resident. All residents were also surveyed to determine their accuracy in identifying their peers' VARK preferences. Resident ABSITE scores were examined for association with preferred learning styles. Twenty-nine residents completed the inventory. Most (18 of 29, 62%) had a multimodal preference, although more than a third (11 of 29, 38%) demonstrated a single-modality preference. Seventy-six percent of all residents (22 of 29) had some degree of kinesthetic (K) learning, while under 50% (14 of 29) were aural (A) learners. Although not significant, dominant (R) learners had the highest mean ABSITE scores. Faculty identified residents' learning styles

    To delineate the learning style that best defines a successful practitioner in the field of neurosurgery by using a validated learning style inventory. The Kolb Learning Style Inventory, a validated assessment tool, was administered to all practicing neurosurgeons, neurosurgical residents, and neurology residents employed at Chang Gung Memorial Hospital, an institution that provides primary and tertiary clinical care in 3 locations, Linkou, Kaohsiung, and Chiayi. There were 81 participants who entered the study, and all completed the study. Neurosurgeons preferred the assimilating learning style (52%), followed by the diverging learning style (39%). Neurosurgery residents were slightly more evenly distributed across the learning styles; however, they still favored assimilating (32%) and diverging (41%). Neurology residents had the most clearly defined preferred learning style with assimilating (76%) obtaining the large majority and diverging (12%) being a distant second. The assimilating and diverging learning styles are the preferred learning styles among neurosurgeons, neurosurgery residents, and neurology residents. The assimilating learning style typically is the primary learning style for neurosurgeons and neurology residents. Neurosurgical residents start off with a diverging learning style and progress toward an assimilating learning style as they work toward becoming practicing neurosurgeons. The field of neurosurgery has limited opportunities for active experimentation, which may explain why individuals who prefer reflective observation are more likely to succeed in this field.

    The purpose of this study was to investigate the effectiveness of preterm infant learning portfolios in enabling mothers to develop infant care knowledge and skills, as well as confidence in their abilities. This study used a quasi-experimental design. The sample consisted of 52 mothers with preterm infants recruited at a neonatal intermediate unit of a medical centre in central Taiwan. Among those, 26 participants in the control group received regular health education and 26 participants in the experimental group received learning portfolios and regular care. The Preterm Infant Care Learning Portfolio (PICLP) is a semi-structured learning portfolio which was provided by nurses. Intervention started with 15 min of instructions on how to use PICLP, including a list of learning task and methods of self-assessment. Follow-up sessions of 5-10 min were conducted after each learning task. The frequency of learning skills could be adjusted depending on participants' learning needs. Self-administered questionnaires regarding knowledge of and skills in preterm infant care and maternal confidence were used to evaluate the effectiveness of the intervention; the questionnaires were conducted before the intervention, 1 day before discharge and 1 month after discharge. We also tracked the frequency with which participants attended instructional sessions before discharged. Mothers' preterm infant care knowledge and skills and confidence improved in both groups after the intervention. The experimental group showed greater improvement than the control group by post-test 2; there was no statistical difference between groups at 1 day before discharge and 1 month after discharge. However, participants in the experimental group came for instructional sessions on baby care for more frequently than the control group. The frequency of learning sessions attended was a predictor of improved scores of the skill assessment before discharge. Both programmes led to improvements in preterm

    In South Africa the submission of a portfolio of learning has become a national requirement for assessment of family medicine training. A national portfolio has been developed, validated and implemented. The aim of this study was to explore registrars' and supervisors' experience regarding the portfolio's educational impact, acceptability, and perceived usefulness for assessment of competence. Semi-structured interviews were conducted with 17 purposively selected registrars and supervisors from all eight South African training programmes. The portfolio primarily had an educational impact through making explicit the expectations of registrars and supervisors in the workplace. This impact was tempered by a lack of engagement in the process by registrars and supervisors who also lacked essential skills in reflection, feedback and assessment. The acceptability of the portfolio was limited by service delivery demands, incongruence between the clinical context and educational requirements, design of the logbook and easy availability of the associated tools. The use of the portfolio for formative assessment was strongly supported and appreciated, but was not always happening and in some cases registrars had even organised peer assessment. Respondents were unclear as to how the portfolio would be used for summative assessment. The learning portfolio had a significant educational impact in shaping work-place based supervision and training and providing formative assessment. Its acceptability and usefulness as a learning tool should increase over time as supervisors and registrars become more competent in its use. There is a need to clarify how it will be used in summative assessment.

    Self-directed learning (SDL) can be as effective as instructor-led training. It employs less instructional resources and is potentially a more efficient educational approach. Although SDL is encouraged among residents in our surgical training program via 24-hour access to surgical task trainers and online modules, residents report that they seldom practice. We hypothesized that a mentor-guided SDL approach would improve practice habits among our residents. From 2011 to 2013, 12 postgraduate year (PGY)-2 general surgery residents participated in a 6-week minimally invasive surgery (MIS) rotation. At the start of the rotation, residents were asked to practice laparoscopic skills until they reached peak performance in at least 3 consecutive attempts at a task (individual proficiency). Trainees met with the staff surgeon at weeks 3 and 6 to evaluate progress and review a graph of their individual learning curve. All trainees subsequently completed a survey addressing their practice habits and suggestions for improvement of the curriculum. By the end of the rotation, 100% of participants improved in all practiced tasks (p mentor-guided SDL. Additionally, 6 (50%) residents reported that their skill level had improved relative to their peers. Some residents (n = 3) felt that the curriculum could be improved by including task-specific goals and additional practice sessions with the staff surgeon. Mentor-guided SDL stimulated surgical residents to practice with greater frequency. This repeated deliberate practice led to significantly improved MIS skills without significantly increasing the need for faculty-led instruction. Some residents preferred more discrete goal setting and increased mentor guidance. Copyright © 2015 Association of Program Directors in Surgery. Published by Elsevier Inc. All rights reserved.

    2016-01-01

    Over recent decades, the use of portfolios in medical education has evolved, and is being applied in undergraduate and postgraduate programs worldwide. Portfolios, as a learning process and method of documenting and assessing learning, is supported as a valuable tool by adult learning theories that stress the need for learners to be self-directed and to engage in experiential learning. Thoughtfully implemented, a portfolio provides learning experiences unequaled by any single learning tool. The credibility (validity) and dependability (reliability) of assessment through portfolios have been questioned owing to its subjective nature; however, methods to safeguard these features have been described in the literature. This paper discusses some of this literature, with particular attention to the role of portfolios in relation to self-reflective learning, provides an overview of current use of portfolios in undergraduate medical education in Saudi Arabia, and proposes research-based guidelines for its implementation and other similar contexts.

    Objective: to investigate the process of learning on human resource management in the radiology residency program at Escola Paulista de Medicina - Universidade Federal de Sao Paulo, aiming at improving radiologists' education. Materials and methods: exploratory study with a quantitative and qualitative approach developed with the faculty staff, preceptors and residents of the program, utilizing a Likert questionnaire (46), taped interviews (18), and categorization based on thematic analysis. Results: According to 71% of the participants, residents have clarity about their role in the development of their activities, and 48% said that residents have no opportunity to learn how to manage their work in a multidisciplinary team. Conclusion: Isolation at medical records room, little interactivity between sectors with diversified and fixed activities, absence of a previous culture and lack of a training program on human resources management may interfere in the development of skills for the residents' practice. There is a need to review objectives of the medical residency in the field of radiology, incorporating, whenever possible, the commitment to the training of skills related to human resources management thus widening the scope of abilities of the future radiologists.

    Portfolio learning enables students to collect evidence of their learning. Component tasks making up a portfolio can be devised that relate directly to intended learning outcomes. Reflective tasks can stimulate students to recognise their own learning needs. Assessment of portfolios using a rating scale relating to intended learning outcomes offers high content validity. This study evaluated a reflective portfolio used during a final-year attachment in general practice (family medicine). Students were asked to evaluate the portfolio (which used significant event analysis as a basis for reflection) as a learning tool. The validity and reliability of the portfolio as an assessment tool were also measured. 81 final-year medical students completed reflective significant event analyses as part of a portfolio created during a three-week attachment (clerkship) in general practice (family medicine). As well as two reflective significant event analyses each portfolio contained an audit and a health needs assessment. Portfolios were marked three times; by the student's GP teacher, the course organiser and by another teacher in the university department of general practice. Inter-rater reliability between pairs of markers was calculated. A questionnaire enabled the students' experience of portfolio learning to be determined. Benefits to learning from reflective learning were limited. Students said that they thought more about the patients they wrote up in significant event analyses but information as to the nature and effect of this was not forthcoming. Moderate inter-rater reliability (Spearman's Rho .65) was found between pairs of departmental raters dealing with larger numbers (20-60) of portfolios. Inter-rater reliability of marking involving GP tutors who only marked 1-3 portfolios was very low. Students rated highly their mentoring relationship with their GP teacher but found the portfolio tasks time-consuming. The inter-rater reliability observed in this study should

    Simulation is increasingly being integrated into medical education; however, there is little research into trainees' perceptions of this learning modality. We elicited trainees' perceptions of simulation-based learning, to inform how simulation is developed and applied to support training. We conducted an instrumental qualitative case study entailing 36 semi-structured one-hour interviews with 12 residents enrolled in an introductory simulation-based course. Trainees were interviewed at three time points: pre-course, post-course, and 4-6 weeks later. Interview transcripts were analyzed using a qualitative descriptive analytic approach. Residents' perceptions of simulation included: 1) simulation serves pragmatic purposes; 2) simulation provides a safe space; 3) simulation presents perils and pitfalls; and 4) optimal design for simulation: integration and tension. Key findings included residents' markedly narrow perception of simulation's capacity to support non-technical skills development or its use beyond introductory learning. Trainees' learning expectations of simulation were restricted. Educators should critically attend to the way they present simulation to learners as, based on theories of problem-framing, trainees' a priori perceptions may delimit the focus of their learning experiences. If they view simulation as merely a replica of real cases for the purpose of practicing basic skills, they may fail to benefit from the full scope of learning opportunities afforded by simulation.

    2015-04-01

    Experiential learning theory and the Kolb Learning Style Inventory (Kolb LSI) have influenced educators worldwide for decades. Knowledge of learning styles can create efficient learning environments, increase information retention, and improve learner satisfaction. Learning styles have been examined in medicine previously, but not specifically with Emergency Medicine (EM) residents and attendings. Using the Kolb LSI, the learning styles of Emergency Medicine residents and attendings were assessed. The findings showed that the majority of EM residents and attendings shared the accommodating learning style. This result was different than prior studies that found the majority of medical professionals had a converging learning style and other studies that found attendings often have different learning styles than residents. The issue of learning styles among emergency medical residents and attendings is important because learning style knowledge may have an impact on how a residency program structures curriculum and how EM residents are successfully, efficiently, and creatively educated.

    To evaluate the effect of learning the laparoscopic sigmoid resection procedure on resident surgeons; establish a minimum number of cases before a resident surgeon could be expected to achieve proficiency with the procedure; and examine if an analysis could be used to measure and support the clinical evaluation of the surgeon's competence with the procedure. Retrospective analysis of data which was prospective entered in the database. From 2003 to 2007 all patients who underwent a laparoscopic sigmoid resection carried out by senior residents, who completed the procedure as the primary surgeon proctored by an experienced surgeon, were included in the study. A cumulative sum control chart (CUSUM) analysis was used evaluate performance. The procedure was defined as a failure if major intra-operative complications occurred such as intra abdominal organ injury, bleeding, or anastomotic leakage; if an inadequate number of lymph nodes (<12 nodes) were removed; or if conversion to an open surgical procedure was required. Thirteen residents performed 169 laparoscopic sigmoid resections in the period evaluated. A significant majority of the resident surgeons were able to consistently perform the procedure without failure after 11 cases and determined to be competent. One resident was not determined to be competent and the CUSUM score supported these findings. We concluded that at least 11 cases are required for most residents to obtain necessary competence with the laparoscopic sigmoid resection procedure. Evaluation with the CUSUM analysis can be used to measure and support the clinical evaluation of the resident surgeon's competence with the procedure.

    The Care of the Elderly (COE) Diploma Program is a six-to-twelve-month enhanced skills program taken after two years of core residency training in Family Medicine. In 2010, we developed and implemented a core-competency-based COE Diploma program (CC), in lieu of one based on learning objectives (LO). This study assessed the effectiveness of the core-competency-based program on residents' learning and their training experience as compared to residents trained using learning objectives. The data from the 2007-2013 COE residents were used in the study, with nine and eight residents trained in the LO and CC programs, respectively. Residents' learning was measured using preceptors' evaluations of residents' skills/abilities throughout the program (118 evaluations in total). Residents' rating of training experience was measured using the Graduate's Questionnaire which residents completed after graduation. For residents' learning, overall, there was no significant difference between the two programs. However, when examined as a function of the four CanMEDS roles, there were significant increases in the CC residents' scores for two of the CanMEDS roles: Communicator/Collaborator/Manager and Scholar compared to residents in the LO program. With respect to residents' training experience, seven out of ten program components were rated by the CC residents higher than by the LO residents. The implementation of a COE CC program appears to facilitate resident learning and training experience.

  8. Portfolio of automated trading systems: complexity and learning set size issues.

    2013-03-01

    In this paper, we consider using profit/loss histories of multiple automated trading systems (ATSs) as N input variables in portfolio management. By means of multivariate statistical analysis and simulation studies, we analyze the influences of sample size (L) and input dimensionality on the accuracy of determining the portfolio weights. We find that degradation in portfolio performance due to inexact estimation of N means and N(N - 1)/2 correlations is proportional to N/L; however, estimation of N variances does not worsen the result. To reduce unhelpful sample size/dimensionality effects, we perform a clustering of N time series and split them into a small number of blocks. Each block is composed of mutually correlated ATSs. It generates an expert trading agent based on a nontrainable 1/N portfolio rule. To increase the diversity of the expert agents, we use training sets of different lengths for clustering. In the output of the portfolio management system, the regularized mean-variance framework-based fusion agent is developed in each walk-forward step of an out-of-sample portfolio validation experiment. Experiments with the real financial data (2003-2012) confirm the effectiveness of the suggested approach.

    To determine incidence of learning goals by competency area and to assess which goals fall into competency areas with lower self-assessment scores. Cross-sectional analysis of existing deidentified American Academy of Pediatrics' PediaLink individualized learning plan data for the academic year 2009-2010. Residents self-assessed competencies in the 6 Accreditation Council for Graduate Medical Education (ACGME) competency areas and wrote learning goals. Textual responses for goals were mapped to 6 ACGME competency areas, future practice, or personal attributes. Adjusted mean differences and associations were estimated using multiple linear and logistic regression. A total of 2254 residents reported 6078 goals. Residents self-assessed their systems-based practice (51.8) and medical knowledge (53.0) competencies lowest and professionalism (68.9) and interpersonal and communication skills (62.2) highest. Residents were most likely to identify goals involving medical knowledge (70.5%) and patient care (50.5%) and least likely to write goals on systems-based practice (11.0%) and professionalism (6.9%). In logistic regression analysis adjusting for postgraduate year (PGY), gender, and degree type (MD/DO), resident-reported goal area showed no association with the learner's relative self-assessment score for that competency area. In the conditional logistic regression analysis, with each learner serving as his or her own control, senior residents (PGY2/3+s) who rated themselves relatively lower in a competency area were more likely to write a learning goal in that area than were PGY1s. Senior residents appear to develop better skills and/or motivation to explicitly turn self-assessed learning gaps into learning goals, suggesting that individualized learning plans may help improve self-regulated learning during residency.

    Full Text Available This article compares learning e-portfolios with profiles in social software environments (like Facebook, MySpace and LinkedIn. The similarities are that both are forums for self representation. The difference between the two is that the self will be represented for different purposes. In the social profile the purpose is to be one among a crowd (whether this crowd is a group of friends or a group of professionals. You can express yourself only through the ways the software deems important. In e-portfolios the purpose is to “show and tell” competences and growth – and to express this in free text and visual fashioning. This is difficult in existing social software. In an e-portfolio the way you represent yourself shows a communicative competence. Should educational institutions then ignore or even ban the use of profiles? The article suggests a way in which they might benefit from a double strategy: Firstly through employment of a programme of learning e-portfolios (Qvortrup, Lund, Ellmin to enable and empower the pupils/students as learners. In the literature on e-portfolios one of the main conclusions is that reflecting on learning enables the learner to understand and appreciate own competences. Secondly, the strategy is to enable the student to benefit from social software ability to establish relations – and to focus on the competence of creating and maintaining professional relationships. This strategy is beneficial because it addresses a problem often encountered when employing a program of e-portfolios. The students feel no “inner need” to fill them out. They do not view the e-portfolio as a means of persuading their readers – possibly because they are, through the e-portfolio, talking to an unknown audience. The e-portfolio is here discussed as rhetorical discourse focusing of Lhoyd Bitzer’s concept of the rhetorical situation. The one thing lacking in establishing a true rhetorical situation in Bitzer’s sense is the

    Trainees are exposed to medical errors throughout medical school and residency. Little is known about what facilitates and limits learning from these experiences. To identify major factors and areas of tension in trainees' learning from medical errors. Structured telephone interviews with 59 trainees (medical students and residents) from 1 academic medical center. Five authors reviewed transcripts of audiotaped interviews using content analysis. Trainees were aware that medical errors occur from early in medical school. Many had an intense emotional response to the idea of committing errors in patient care. Students and residents noted variation and conflict in institutional recommendations and individual actions. Many expressed role confusion regarding whether and how to initiate discussion after errors occurred. Some noted the conflict between reporting errors to seniors who were responsible for their evaluation. Learners requested more open discussion of actual errors and faculty disclosure. No students or residents felt that they learned better from near misses than from actual errors, and many believed that they learned the most when harm was caused. Trainees are aware of medical errors, but remaining tensions may limit learning. Institutions can immediately address variability in faculty response and local culture by disseminating clear, accessible algorithms to guide behavior when errors occur. Educators should develop longitudinal curricula that integrate actual cases and faculty disclosure. Future multi-institutional work should focus on identified themes such as teaching and learning in emotionally charged situations, learning from errors and near misses and balance between individual and systems responsibility.

    In the Next Accreditation System, the Accreditation Council for Graduate Medical Education outlines milestones for medical knowledge and requires regular didactic sessions in residency training. There are many challenges to facilitating active learning in resident conferences, and we need to better understand resident learning preferences and faculty perspectives on facilitating active learning. The goal of this study was to identify challenges to facilitating active learning in resident conferences, both through identifying specific implementation barriers and identifying differences in perspective between faculty and residents on effective teaching and learning strategies. The investigators invited core residency faculty to participate in focus groups. The investigators used a semistructured guide to facilitate discussion about learning preferences and teaching perspectives in the conference setting and used an 'editing approach' within a grounded theory framework to qualitative analysis to code the transcripts and analyze the results. Data were compared to previously collected data from seven resident focus groups. Three focus groups with 20 core faculty were conducted. We identified three domains pertaining to facilitating active learning in resident conferences: barriers to facilitating active learning formats, similarities and differences in faculty and resident learning preferences, and divergence between faculty and resident opinions about effective teaching strategies. Faculty identified several setting, faculty, and resident barriers to facilitating active learning in resident conferences. When compared to residents, faculty expressed similar learning preferences; the main differences were in motivations for conference attendance and type of content. Resident preferences and faculty perspectives differed on the amount of information appropriate for lecture and the role of active participation in resident conferences. This study highlights several

    Team-based learning (TBL) is used in undergraduate medical education to facilitate higher-order content learning, promote learner engagement and collaboration, and foster positive learner attitudes. There is a paucity of data on the use of TBL in graduate medical education. Our aim was to assess resident engagement, learning, and faculty/resident satisfaction with TBL in internal medicine residency ambulatory education. Survey and nominal group technique methodologies were used to assess learner engagement and faculty/resident satisfaction. We assessed medical learning using individual (IRAT) and group (GRAT) readiness assurance tests. Residents (N = 111) involved in TBL sessions reported contributing to group discussions and actively discussing the subject material with other residents. Faculty echoed similar responses, and residents and faculty reported a preference for future teaching sessions to be offered using the TBL pedagogy. The average GRAT score was significantly higher than the average IRAT score by 22%. Feedback from our nominal group technique rank ordered the following TBL strengths by both residents and faculty: (1) interactive format, (2) content of sessions, and (3) competitive nature of sessions. We successfully implemented TBL pedagogy in the internal medicine ambulatory residency curriculum, with learning focused on the care of patients in the ambulatory setting. TBL resulted in active resident engagement, facilitated group learning, and increased satisfaction by residents and faculty. To our knowledge this is the first study that implemented a TBL program in an internal medicine residency curriculum.

    Surgical education is evolving under the dual pressures of an enlarging body of knowledge required during residency and mounting work-hour restrictions. Changes in surgical residency training need to be based on available educational models and research to ensure successful training of surgeons. Experiential learning theory, developed by David Kolb, demonstrates the importance of individual learning styles in improving learning. This study helps elucidate the way in which medical students, surgical residents, and surgical faculty learn. The Kolb Learning Style Inventory, which divides individual learning styles into Accommodating, Diverging, Converging, and Assimilating categories, was administered to the second year undergraduate medical students, general surgery resident body, and general surgery faculty at the University of Alberta. A total of 241 faculty, residents, and students were surveyed with an overall response rate of 73%. The predominant learning style of the medical students was assimilating and this was statistically significant (p learning style found in the residents and faculty. The predominant learning styles of the residents and faculty were convergent and accommodative, with no statistically significant differences between the residents and the faculty. We conclude that medical students have a significantly different learning style from general surgical trainees and general surgeons. This has important implications in the education of general surgery residents.

    To identify the learning styles of a group of cardiology residents (R) undergoing a training program at the University of Buenos Aires and to identify correlations of these styles. Statistical data were obtained through a 120-question survey developed by Vermunt and colleagues, which identified four different learning styles: construction-directed; reproduction-directed; application-directed; and undirected. Four variables were identified [gender, previous experience as a teaching assistant (TA) in medical school, university final average (FA) and the public or private institution/centre of origin] in order to analyse level of correlation with learning styles (LS). Between April 2001 and April 2002, 149 residents (R) completed the survey. Average age was 29 (+/-2.7) years old; with 63% being men. The predominant LS were oriented toward knowledge application. In terms of variables, no differences regarding gender were detected; the R with TA showed undirected LS characteristics; those with a low FA registered a tendency towards reproduction-directed LS; and those residents at public/state medical centres indicated construction-directed LS tendencies. An application-directed learning style predominates in this group of residents. Information regarding learning styles can provide foundations upon which arguments can be made for changes in education that are traditionally not evidence-based.

    To determine family medicine residents' learning behaviour and preferences outside of clinical settings in order to help guide the development of an effective academic program that can maximize their learning. Retrospective descriptive analysis of academic learning logs submitted by residents as part of their academic training requirements between 2008 and 2011. London, Ont. All family medicine residents at Western University who had completed their academic program requirements (N = 72) by submitting 300 or more credits (1 credit = 1 hour). Amount of time spent on various learning modalities, location where the learning took place, resources used for self-study, and the objective of the learning activity. A total of 72 residents completed their academic requirements during the study period and logged a total of 25 068 hours of academic learning. Residents chose to spend most of their academic time engaging in self-study (44%), attending staff physicians' teaching sessions (20%),and participating in conferences, courses, or workshops (12%) and in postgraduate medical education sessions (12%). Textbooks (26%), medical journals (20%), and point-of-care resources (12%) were the 3 most common resources used for self-study. The hospital (32%), residents' homes (32%),and family medicine clinics (14%) were the most frequently cited locations where academic learning occurred. While all physicians used a variety of educational activities, most residents (67%) chose self-study as their primary method of learning. The topic for academic learning appeared to have some influence on the learning modalities used by residents. Residents used a variety of learning modalities and chose self-study over other more traditional modalities (eg, lectures) for most of their academic learning. A successful academic program must take into account residents' various learning preferences and habits while providing guidance and training in the use of more effective learning methods and

    Theoretical knowledge in biology and medicine plays a substantial role in laboratory medicine resident education. In this study, we assessed the contribution of problem-based learning (PBL) to improve the training of laboratory medicine residents during their internship in the department of virology, Strasbourg University Hospital, France. We compared the residents' satisfaction regarding an educational program based on PBL and a program based on lectures and presentations. PBL induced a high level of satisfaction (100%) among residents compared to lectures and presentations (53%). The main advantages of this technique were to create a situational interest regarding virological problems, to boost the residents' motivation and to help them identify the most relevant learning objectives in virology. However, it appears pertinent to educate the residents in appropriate bibliographic research techniques prior to PBL use and to monitor their learning by regular formative assessment sessions.

  10. Residents' perceptions of their teachers: facilitative behaviour and the learning value of rotations.

    Despite changes in modern medicine the role of the clinical teacher remains central to medical residents' education and rotations continue to be their dominant educational context. Residents have strong positive feelings for clinical teachers who are perceived as interested in teaching and for those rotations that provide a balance of educational opportunities and patient care responsibilities. Research in residency education has focused on teacher behaviours used to teach medical residents clinical information or patient care skills but has neglected teacher behaviours used to facilitate effective learning relationships with residents. To explore the impact of clinical teachers' use of facilitative behaviours on residents' educational experience, we use concepts stemming from the psychologist Carl Rogers' work previously shown to be associated with positive learning outcomes--empathy, unconditional positive regard, and congruence. These constructs are measured by the use of the four scales of the Barrett-Lennard Relationship Inventory (BLRI)--level of regard, unconditionality of regard, congruence and empathy. Our study measures the correlation between residents' perceptions of clinical teachers' use of facilitative behaviours and residents' evaluation of the learning value of rotations. Thirty-three residents completed the BLRI on a different clinical teacher for each of six monthly rotations. A total of 158 surveys were returned. There were strong positive correlations between three of the BLRI variables and residents' perception of the learning value of rotations. Potential uses of these findings are discussed.

    The Computer Book of the Internal Medicine resident (CBIMR) is a computer program that was validated to analyze the acquisition of competences in teams of Internal Medicine residents. To analyze the characteristics of the rotations during the Internal Medicine residency and to identify the variables associated with the acquisition of clinical and communication skills, the achievement of learning objectives and resident satisfaction. All residents of our service (n=20) participated in the study during a period of 40 months. The CBIMR consisted of 22 self-assessment questionnaires specific for each rotation, with items on services (clinical workload, disease protocolization, resident responsibilities, learning environment, service organization and teamwork) and items on educational outcomes (acquisition of clinical and communication skills, achievement of learning objectives, overall satisfaction). Associations between services features and learning outcomes were analyzed using bivariate and multivariate analysis. An intense clinical workload, high resident responsibilities and disease protocolization were associated with the acquisition of clinical skills. High clinical competence and teamwork were both associated with better communication skills. Finally, an adequate learning environment was associated with increased clinical competence, the achievement of educational goals and resident satisfaction. Potentially modifiable variables related with the operation of clinical services had a significant impact on the acquisition of clinical and communication skills, the achievement of educational goals, and resident satisfaction during the specialized training in Internal Medicine.

    Although emergency departments provide acute care learning opportunities for medical students, student exposure to recommended curriculum presentations and procedures are limited. In this perspective, clinical environments providing learning opportunities for students should be monitored as part of an ongoing quality improvement process. This study aims to analyze student exposures and their involvement levels in two different hospitals (Tawam and Al Ain) so as to improve the teaching and learning activities. This is a prospective study on all 76 final year medical students' electronic logbooks (e-Portfolio) of the academic year 2016/2017. Students recorded 5087 chief complaints and 3721 procedures. The average patient and procedure exposure in a shift per student in Al Ain Hospital compared with Tawam Hospital were 7.2 vs 6.4 and 5.8 vs 4.3, respectively. The highest full involvement with presentations was seen in the pediatric unit (67.1%, P portfolio has proven to be a very useful tool in defining the learning activities of final year medical students during their emergency medicine clerkship and in comparing activities in two different clinical settings.

    Board certification is an important professional qualification and a prerequisite for credentialing, and the Accreditation Council for Graduate Medical Education (ACGME) assesses board certification rates as a component of residency program effectiveness. To date, research has shown that preresidency measures, including National Board of Medical Examiners scores, Alpha Omega Alpha Honor Medical Society membership, or medical school grades poorly predict postresidency board examination scores. However, learning styles and temperament have been identified as factors that 5 affect test-taking performance. The purpose of this study is to characterize the learning styles and temperaments of pediatric residents and to evaluate their relationships to yearly in-service and postresidency board examination scores. This cross-sectional study analyzed the learning styles and temperaments of current and past pediatric residents by administration of 3 validated tools: the Kolb Learning Style Inventory, the Keirsey Temperament Sorter, and the Felder-Silverman Learning Style test. These results were compared with known, normative, general and medical population data and evaluated for correlation to in-service examination and postresidency board examination scores. The predominant learning style for pediatric residents was converging 44% (33 of 75 residents) and the predominant temperament was guardian 61% (34 of 56 residents). The learning style and temperament distribution of the residents was significantly different from published population data (P  =  .002 and .04, respectively). Learning styles, with one exception, were found to be unrelated to standardized test scores. The predominant learning style and temperament of pediatric residents is significantly different than that of the populations of general and medical trainees. However, learning styles and temperament do not predict outcomes on standardized in-service and board examinations in pediatric residents.

    Background: the learning styles are cognitive, emotional, and psychological characteristics, which function as relatively stable indicators of how teachers and students perceive, interact, and respond to their learning environments. Knowing students' styles allows teachers to have tools to improve medical education. Our objective was to identify learning styles in pediatric residents and professors from a pediatric hospital. Methods: a learning styles questionnaire was applied to residents and theirs professors; data was analyzed in SPSS 12 software. Results: the dominant learning style in pediatric residents was reflexive and for professors was theoretical. There wasn't any difference between sexes or between medical or surgical specialities. There was more correlation between professors and residents when there was an increase in training time. Conclusions: the learning styles between professors and residents are different, especially at the beginning of the medical specialty courses; that's why it is necessary to realize a confrontation between the students' learning styles and teaching methods used by professors to improve significant learning. To know learning styles gives residents an important alternative to find a better study strategy.

    A "flipped classroom" educational model exchanges the traditional format of a classroom lecture and homework problem set. We piloted two flipped classroom sessions in our emergency medicine (EM) residency didactic schedule. We aimed to learn about resident and faculty impressions of the sessions, in order to develop them as a regular component of our residency curriculum. We evaluated residents' impression of the asynchronous video component and synchronous classroom component using four Likert items. We used open-ended questions to inquire about resident and faculty impressions of the advantages and disadvantages of the format. For the Likert items evaluating the video lectures, 33/35 residents (94%, 95% CI 80%-99%) responded that the video lecture added to their knowledge about the topic, and 33/35 residents felt that watching the video was a valuable use of their time. For items evaluating the flipped classroom format, 36/38 residents (95%, 95% CI 82%-99%) preferred the format to a traditional lecture on the topic, and 38/38 residents (100%, 95% CI 89%-100%) felt that the small group session was effective in helping them learn about the topic. Most residents preferred to see the format monthly in our curriculum and chose an ideal group size of 5.5 (first session) and 7 (second session). Residents cited the interactivity of the sessions and access to experts as advantages of the format. Faculty felt the ability to assess residents' understanding of concepts and provide feedback were advantages. Our flipped classroom model was positively received by EM residents. Residents preferred a small group size and favored frequent use of the format in our curriculum. The flipped classroom represents one modality that programs may use to incorporate a mixture of asynchronous and interactive synchronous learning and provide additional opportunities to evaluate residents.

    This paper presents a review to explore the literature focusing on portfolio in postgraduate general practice (GP) training, and to examine the impact of implementation of portfolio on learning process, as well as proposing recommendations for its implementation in postgraduate GP training. An electronic search was carried out on several databases for studies addressing portfolio in postgraduate GP training. Six articles were included to address specifically the effectiveness of portfolio in postgraduate GP training. Five of them described successful experiences of portfolio-based learning implementation. Only one article addressed portfolio-based assessment in postgraduate GP training. The existing evidence provides various benefits of professional portfolio-based learning. It does appear to have advantages of stimulating reflective learning, promoting proactive learning, and bridging the hospital experiences of the learners to GP. Moreover, the challenges to implementation of portfolio-based learning are often based on orientation and training of stakeholders.

    Full Text Available Abstract Background Surgical education is evolving under the dual pressures of an enlarging body of knowledge required during residency and mounting work-hour restrictions. Changes in surgical residency training need to be based on available educational models and research to ensure successful training of surgeons. Experiential learning theory, developed by David Kolb, demonstrates the importance of individual learning styles in improving learning. This study helps elucidate the way in which medical students, surgical residents, and surgical faculty learn. Methods The Kolb Learning Style Inventory, which divides individual learning styles into Accommodating, Diverging, Converging, and Assimilating categories, was administered to the second year undergraduate medical students, general surgery resident body, and general surgery faculty at the University of Alberta. Results A total of 241 faculty, residents, and students were surveyed with an overall response rate of 73%. The predominant learning style of the medical students was assimilating and this was statistically significant (p Conclusions We conclude that medical students have a significantly different learning style from general surgical trainees and general surgeons. This has important implications in the education of general surgery residents.

    Many residency programs offer training in evidence-based medicine (EBM). However, these curricula often fail to achieve optimal learning outcomes, perhaps because they neglect various contextual factors in the learning environment. We developed and validated an instrument to characterize the environment for EBM learning and practice in residency programs. An EBM Environment Scale was developed following scale development principles. A survey was administered to residents across six programs in primary care specialties at four medical centers. Internal consistency reliability was analyzed with Cronbach's coefficient alpha. Validity was assessed by comparing predetermined subscales with the survey's internal structure as assessed via factor analysis. Scores were also compared for subgroups based on residency program affiliation and residency characteristics. Out of 262 eligible residents, 124 completed the survey (response rate 47%). The overall mean score was 3.89 (standard deviation=0.56). The initial reliability analysis of the 48-item scale had a high reliability coefficient (Cronbach α=.94). Factor analysis and further item analysis resulted in a shorter 36-item scale with a satisfactory reliability coefficient (Cronbach α=.86). Scores were higher for residents with prior EBM training in medical school (4.14 versus 3.62) and in residency (4.25 versus 3.69). If further testing confirms its properties, the EBM Environment Scale may be used to understand the influence of the learning environment on the effectiveness of EBM training. Additionally, it may detect changes in the EBM learning environment in response to programmatic or institutional interventions.

    To train surgeons effectively, it is important to understand how they are learning. The Kolb Learning Style Inventory (LSI) is based on the theory of experiential learning, which divides the learning cycle into 4 stages: active experimentation (AE), abstract conceptualization (AC), concrete experience, and reflective observation. The purpose of this investigation was to assess the learning styles of orthopedic residents, faculty, and applicants at an east-coast residency program. A total of 90 Kolb LSI, Version 3.1 surveys, and demographic questionnaires were distributed to all residency applicants, residents, and faculty at an academic program. Data collected included age, sex, type of medical school (MD or DO), foreign medical graduate status, and either year since college graduation, postgraduate year level (residents only), or years since completion of residency (faculty only). Seventy-one completed Kolb LSI surveys (14 residents, 14 faculty members, and 43 applicants) were recorded and analyzed for statistical significance. The most prevalent learning style among all participants was converging (53.5%), followed by accommodating (18.3%), diverging (18.3%), and assimilating (9.9%) (p = 0.13). The applicant and resident groups demonstrated a high tendency toward AE followed by AC. The faculty group demonstrated a high tendency toward AC followed by AE. None of the 24 subjects who were 26 years or under had assimilating learning styles, in significant contrast to the 12% of 27- to 30-year-olds and 18% of 31 and older group (p learning style involves problem solving and decision making, with the practical application of ideas and the use of hypothetical-deductive reasoning. Learning through AE decreased with age, whereas learning through AC increased. Copyright © 2014 Association of Program Directors in Surgery. Published by Elsevier Inc. All rights reserved.

    Objective: To evaluate the effect of simulation-based mastery learning (SBML) on internal medicine residents' lumbar puncture (LP) skills, assess neurology residents' acquired LP skills from traditional clinical education, and compare the results of SBML to traditional clinical education. Methods: This study was a pretest-posttest design with a comparison group. Fifty-eight postgraduate year (PGY) 1 internal medicine residents received an SBML intervention in LP. Residents completed a baseline skill assessment (pretest) using a 21-item LP checklist. After a 3-hour session featuring deliberate practice and feedback, residents completed a posttest and were expected to meet or exceed a minimum passing score (MPS) set by an expert panel. Simulator-trained residents' pretest and posttest scores were compared to assess the impact of the intervention. Thirty-six PGY2, 3, and 4 neurology residents from 3 medical centers completed the same simulated LP assessment without SBML. SBML posttest scores were compared to neurology residents' baseline scores. Results: PGY1 internal medicine residents improved from a mean of 46.3% to 95.7% after SBML (p < 0.001) and all met the MPS at final posttest. The performance of traditionally trained neurology residents was significantly lower than simulator-trained residents (mean 65.4%, p < 0.001) and only 6% met the MPS. Conclusions: Residents who completed SBML showed significant improvement in LP procedural skills. Few neurology residents were competent to perform a simulated LP despite clinical experience with the procedure. PMID:22675080

    E-learning-the use of Internet technologies to enhance knowledge and performance-has become a widely accepted instructional approach. Little is known about the current use of e-learning in postgraduate medical education. To determine utilization of e-learning by United States internal medicine residency programs, program director (PD) perceptions of e-learning, and associations between e-learning use and residency program characteristics. We conducted a national survey in collaboration with the Association of Program Directors in Internal Medicine of all United States internal medicine residency programs. Of the 368 PDs, 214 (58.2%) completed the e-learning survey. Use of synchronous e-learning at least sometimes, somewhat often, or very often was reported by 85 (39.7%); 153 programs (71.5%) use asynchronous e-learning at least sometimes, somewhat often, or very often. Most programs (168; 79%) do not have a budget to integrate e-learning. Mean (SD) scores for the PD perceptions of e-learning ranged from 3.01 (0.94) to 3.86 (0.72) on a 5-point scale. The odds of synchronous e-learning use were higher in programs with a budget for its implementation (odds ratio, 3.0 [95% CI, 1.04-8.7]; P = .04). Residency programs could be better resourced to integrate e-learning technologies. Asynchronous e-learning was used more than synchronous, which may be to accommodate busy resident schedules and duty-hour restrictions. PD perceptions of e-learning are relatively moderate and future research should determine whether PD reluctance to adopt e-learning is based on unawareness of the evidence, perceptions that e-learning is expensive, or judgments about value versus effectiveness.

    A constant rebalanced portfolio is an asset allocation algorithm which keeps the same distribution of wealth among a set of assets along a period of time. Recently, there has been work on on-line portfolio selection algorithms which are competitive with the best constant rebalanced portfolio determined in hindsight (Cover, 1991; Helmbold et al., 1996; Cover and Ordentlich, 1996). By their nature, these algorithms employ the assumption that high returns can be achieved using a fixed asset allocation strategy. However, stock markets are far from being stationary and in many cases the wealth achieved by a constant rebalanced portfolio is much smaller than the wealth achieved by an ad hoc investment strategy that adapts to changes in the market. In this paper we present an efficient portfolio selection algorithm that is able to track a changing market. We also describe a simple extension of the algorithm for the case of a general transaction cost, including the transactions cost models recently investigated in (Blum and Kalai, 1997). We provide a simple analysis of the competitiveness of the algorithm and check its performance on real stock data from the New York Stock Exchange accumulated during a 22-year period. On this data, our algorithm outperforms all the algorithms referenced above, with and without transaction costs.

    An Institute of Medicine report issued in 2002 cited cross-cultural training as a mechanism to address racial and ethnic disparities in health care, but little is known about residents' training and capabilities to provide quality care to diverse populations. This article explores a select group of residents' perceptions of their preparedness to deliver quality care to diverse populations. Seven focus groups and ten individual interviews were conducted with 68 residents in locations nationwide. Qualitative analysis of focus-group and individual interview transcripts was performed to assess residents' perceptions of (1) preparedness to deliver care to diverse patients; (2) educational climate; and (3) training experiences. Most residents in this study noted the importance of cross-cultural care yet reported little formal training in this area. Residents wanted more formal training yet expressed concern that culture-specific training could lead to stereotyping. Most residents had developed ad hoc, informal skills to care for diverse patients. Although residents perceived institutional endorsement, they sensed it was a low priority due to lack of time and resources. Residents in this study reported receiving mixed messages about cross-cultural care. They were told it is important, yet they received little formal training and did not have time to treat diverse patients in a culturally sensitive manner. As a result, many developed coping behaviors rather than skills based on formally taught best practices. Training environments need to increase training to enhance residents' preparedness to deliver high-quality cross-cultural care if the medical profession is to achieve the goals set by the Institute of Medicine.

    Introduction A “flipped classroom” educational model exchanges the traditional format of a classroom lecture and homework problem set. We piloted two flipped classroom sessions in our emergency medicine (EM) residency didactic schedule. We aimed to learn about resident and faculty impressions of the sessions, in order to develop them as a regular component of our residency curriculum. Methods We evaluated residents’ impression of the asynchronous video component and synchronous classroom component using four Likert items. We used open-ended questions to inquire about resident and faculty impressions of the advantages and disadvantages of the format. Results For the Likert items evaluating the video lectures, 33/35 residents (94%, 95% CI 80%–99%) responded that the video lecture added to their knowledge about the topic, and 33/35 residents felt that watching the video was a valuable use of their time. For items evaluating the flipped classroom format, 36/38 residents (95%, 95% CI 82%–99%) preferred the format to a traditional lecture on the topic, and 38/38 residents (100%, 95% CI 89%–100%) felt that the small group session was effective in helping them learn about the topic. Most residents preferred to see the format monthly in our curriculum and chose an ideal group size of 5.5 (first session) and 7 (second session). Residents cited the interactivity of the sessions and access to experts as advantages of the format. Faculty felt the ability to assess residents’ understanding of concepts and provide feedback were advantages. Conclusion Our flipped classroom model was positively received by EM residents. Residents preferred a small group size and favored frequent use of the format in our curriculum. The flipped classroom represents one modality that programs may use to incorporate a mixture of asynchronous and interactive synchronous learning and provide additional opportunities to evaluate residents.

    Active engagement in the learning process is important to enhance learners' knowledge acquisition and retention and the development of their thinking skills. This study evaluated whether a 1-hour faculty development workshop increased the use of active teaching strategies and enhanced residents' active learning and thinking. Faculty teaching in a pediatrics residency participated in a 1-hour workshop (intervention) approximately 1 month before a scheduled lecture. Participants' responses to a preworkshop/postworkshop questionnaire targeted self-efficacy (confidence) for facilitating active learning and thinking and providing feedback about workshop quality. Trained observers assessed each lecture (3-month baseline phase and 3-month intervention phase) using an 8-item scale for use of active learning strategies and a 7-item scale for residents' engagement in active learning. Observers also assessed lecturer-resident interactions and the extent to which residents were asked to justify their answers. Responses to the workshop questionnaire (n  =  32/34; 94%) demonstrated effectiveness and increased confidence. Faculty in the intervention phase demonstrated increased use of interactive teaching strategies for 6 items, with 5 reaching statistical significance (P ≤ .01). Residents' active learning behaviors in lectures were higher in the intervention arm for all 7 items, with 5 reaching statistical significance. Faculty in the intervention group demonstrated increased use of higher-order questioning (P  =  .02) and solicited justifications for answers (P  =  .01). A 1-hour faculty development program increased faculty use of active learning strategies and residents' engagement in active learning during resident core curriculum lectures.

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

    Several studies have examined how doctors learn in the workplace, but research is needed linking workplace learning with the organisation of doctors' daily work. This study examined residents' and consultants' attitudes and beliefs regarding workplace learning and contextual and organisational factors influencing the organisation and planning of medical specialist training. An explorative case study in three paediatric departments in Denmark including 9 days of field observations and focus group interviews with 9 consultants responsible for medical education and 16 residents. The study aimed to identify factors in work organisation facilitating and hindering residents' learning. Data were coded through an iterative process guided by thematic analysis. Findings illustrate three main themes: (1) Learning beliefs about patient care and apprenticeship learning as inseparable in medical practice. Beliefs about training and patient care expressed in terms of training versus production caused a potential conflict. (2) Learning context. Continuity over time in tasks and care for patients is important, but continuity is challenged by the organisation of daily work routines. (3) Organisational culture and regulations were found to be encouraging as well inhibiting to a successful organisation of the work in regards to learning. Our findings stress the importance of consultants' and residents' beliefs about workplace learning as these agents handle the potential conflict between patient care and training of health professionals. The structuring of daily work tasks is a key factor in workplace learning as is an understanding of underlying relations and organisational culture in the clinical departments.

    Full Text Available Introduction: the method and way of learning and teaching are effective in acquiring clinical skills, and identifying the shortcomings of learning and teaching will lead to better planning. The purpose of this study was to explain the experiences of the learning clinical procedures of the internal medicine residents in gastroenterology department. Methods: qualitative study using content thematic analysis was done. Six fourth-year residents were selected and interviewed considering purposive sampling. The data of the interviews were transcribed and analyzed after rereading. Results: the collected data are divided into three categories: learning and experience with the following four categories (learning time and experiencing, leaning and experiencing times, learning and experiencing opportunities, training and the lack of the training of some procedures. These categories are explained by using some quotes derived from the data. Conclusion: the results of this study suggest that the administrative management of internal residency is poor and should get seriously in implementation and application of intended instructions existing in the prepared program of Medical Education and Specialized Council of internal residency period. The attending physicians and residents must be aware of the content of education program at the beginning of the residency periods and the trainers must try to supervise the residents’ education.

    Concerns exist about the negative impact of burnout on the professional and personal lives of residents. It is suggested that the origins of burnout among residents are rooted in the learning environment. We aimed to evaluate the association between the learning environment and burnout in a national sample of Dutch residents. We conducted a cross-sectional online survey among all Dutch residents in September 2015. We measured the learning environment using the three domain scores on content, organization, and atmosphere from the Scan of Postgraduate Educational Environment Domains (SPEED) and burnout using the Dutch version of the Maslach Burnout Inventory (UBOS-C). Of 1,231 responding residents (33 specialties), 185 (15.0%) met criteria for burnout. After adjusting for demographic (age, gender and marital status) and work-related factors (year of training, type of teaching hospital and type of specialty), we found a consistent inverse association between SPEED scores and the risk of burnout (aOR 0.54, 95% CI 0.46 to 0.62, p burnout among residents. This suggests that the learning environment is of key importance in preventing resident burnout.

    Contextual factors are known to influence the acquisition and application of communication skills in clinical settings. Little is known about residents' perceptions of these factors. This article aims to explore residents' perceptions of contextual factors affecting the acquisition and application of communication skills in the medical workplace. We conducted an exploratory study comprising seven focus groups with residents in two different specialities: general practice (n=23) and surgery (n=18). Residents perceive the use of summative assessment checklists that reduce communication skills to behavioural components as impeding the learning of their communication skills. Residents perceive encouragement to deliberately practise in an environment in which the value of communication skills is recognised and support is institutionalised with appropriate feedback from role models as the most important enhancing factors in communication skills learning. To gradually realise a clinical working environment in which the above results are incorporated, we propose to use transformative learning theory to guide further studies. Provided it is used continuously, an approach that combines self-directed learning with observation and discussion of resident-patient consultations seems an effective method for transformative learning of communication skills.

Among the different learning and assessment initiatives introduced in the slipstream of this paradigmatic turn, the portfolio seems...... to have become one of the most popular. By re-describing the portfolio from a systems theoretical point of view, this article discusses established expectations of the portfolio in relation to transparency in learning, reflexivity and self-assessment. It shows that the majority of the literature deals...... with what-questions and that the portfolio is expected to handle a number of challenges with regard to the documentation of learning processes and achievements as well as the conditioning of learning activities. Furthermore, is becomes clear that descriptions of how the portfolio works are sparse. Based...

    Simulation-based training is currently embedded in most health professions education curricula. Without evidence for how trainees think about their simulation-based learning, some training techniques may not support trainees' learning strategies. This study explored how residents think about and self-regulate learning during a lumbar puncture (LP) training session using a simulator. In 2010, 20 of 45 postgraduate year 1 internal medicine residents attended a mandatory procedural skills training boot camp. Independently, residents practiced the entire LP skill on a part-task trainer using a clinical LP tray and proper sterile technique. We interviewed participants regarding how they thought about and monitored their learning processes, and then we conducted a thematic analysis of the interview data. The analysis suggested that participants considered what they could and could not learn from the simulator; they developed their self-confidence by familiarizing themselves with the LP equipment and repeating the LP algorithmic steps. Participants articulated an idiosyncratic model of learning they used to interpret the challenges and successes they experienced. Participants reported focusing on obtaining cerebrospinal fluid and memorizing the "routine" version of the LP procedure. They did not report much thinking about their learning strategies (eg, self-questioning). During simulation-based training, residents described assigning greater weight to achieving procedural outcomes and tended to think that the simulated task provided them with routine, generalizable skills. Over this typical 1-hour session, trainees did not appear to consider their strategic mindfulness (ie, awareness and use of learning strategies).

    To explore what third-year medical students learn from residents and which teaching strategies are used by excellent resident teachers in their interactions with students in the clinical workplace environment. In this multi-institutional qualitative study between January and March 2012, the authors conducted focus groups with medical students who were midway through their third year. Qualitative analysis was used to identify themes. Thirty-seven students participated. Students contributed 228 comments related to teaching methods used by residents. The authors categorized these into 20 themes within seven domains: role-modeling, focusing on teaching, creating a safe learning environment, providing experiential learning opportunities, giving feedback, setting expectations, and stimulating learning. Role-modeling, the most frequently classified method of teaching in this study, was not included in three popular "Resident-as-Teacher" (RAT) models. Strategies including offering opportunities for safe practice, involving students in the team, and providing experiential learning opportunities were not emphasized in these models either. Almost 200 comments representing the knowledge and skills students learned from residents were categorized into 33 themes within nine domains: patient care, communication, navigating the system, adaptability, functioning as a student/resident, lifelong learning, general comments, career/professional development, and medical content. Most of these areas are not emphasized in popular RAT models. Residents serve as critically important teachers of students in the clinical workplace. Current RAT models are based largely on the teaching behaviors of faculty. The content and teaching strategies identified by students in this study should serve as the foundation for future RAT program development.

    Blended learning environments - involving both face-to-face and remote interactions - make it easier to adapt learning programs to constraints such as residents' location and low teacher-student ratio. Social networking sites (SNS) such as Facebook®, while not originally intended to be used as learning environments, may be adapted for the distance-learning part of training programs. The purpose of our study was to explore the use of SNS for asynchronous distance learning in a blended learning environment as well as its influence on learners' face-to-face interactions. We conducted a qualitative study and carried out semi-structured interviews. We performed purposeful sampling for maximal variation to include eight general practice residents in 2(nd) and 3(rd) year training. A thematic analysis was performed. The social integration of SNS facilitates the engagement of users in their learning tasks. This may also stimulate students' interactions and group cohesion when members meet up in person. Most of the general practice residents who work in the blended learning environment we studied had a positive appraisal on their use of SNS. In particular, we report a positive impact on their engagement in learning and their participation in discussions during face-to-face instruction. Further studies are needed in order to evaluate the effectiveness of SNS in blended learning environments and the appropriation of SNS by teachers.

    There are different teaching styles for delivering competency-based curricula. The education literature suggests that learning is maximized when teaching is delivered in a style preferred by learners. To determine if dermatology residents report learning style preferences aligned with adult learning. Dermatology residents attending an introductory cutaneous biology course completed a learning styles inventory assessing self-reported success in 35 active and passive learning activities. The 35 learning activities were ranked in order of preference by learners. Mean overall ratings for active learning activities were significantly higher than for passive learning activities (P = 0.002). Trends in dermatology resident learning style preferences should be considered during program curriculum development. Programs should integrate a variety of curriculum delivery methods to accommodate various learning styles, with an emphasis on the active learning styles preferred by residents.

    Informal learning includes all occurrences during one's life when learning is not deliberate. Prior research on informal learning in healthcare contexts examined learning happening outside of the formal curriculum, yet still in the workplace. This study explores residents' perceptions about extracurricular factors outside of the workplace that contribute to their learning and development of professional identity, whether interpersonal relations are recognised as such factors, and positive and negative impacts of interpersonal relations. In this qualitative study, all 21 residents in our Emergency Medicine programme were asked, in a web-based survey with open-ended questions, to identify extracurricular sources outside of the workplace perceived as contributing to their learning and professional identity development, and list positive and negative impacts of interpersonal relations outside of work on learning and identity development. Themes were extracted through content analysis of the narrative responses. Two reviewers coded all data. Thirteen (62%) residents identified 37 factors grouped under five themes: learning activity, role modelling, support, non-clinical academic roles, and social interactions. Interpersonal relations were perceived as having positive and negative impacts, including creating support, positive role modelling and mentoring, increasing concrete learning, as well as lapses in teaching skills, deficits in professional role training, and loss of personal time. Several extracurricular factors outside of the workplace contribute to resident learning and identity development, including interpersonal relations, which have positive and negative impacts. The most often noted negative impact of interpersonal relations outside of work between residents and faculty related to perceived lapses in teaching skills. © 2018 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

    Full Text Available Problem Graduate medical education programs are expected to educate residents to be able to manage critically ill patients. Most obstetrics and gynecology (OB/GYN graduate medical education programs provide education primarily in a didactic format in a traditional face-to-face setting. Busy clinical responsibilities tend to limit resident engagement during these educational sessions. The revision of the training paradigm to a more learner-centered approach is suggested. Intervention A blended learning education program was designed and implemented to facilitate the teaching and learning of obstetric emergencies, specifically diabetic ketoacidosis and acute-onset severe hypertension in pregnancy. The program incorporated tools to foster a community of inquiry. Multimedia presentations were also utilized as the main modality to provide instruction. The blended learning course was designed in accordance with the cognitive theory of multimedia learning. Context This intervention was carried out in the Department of Obstetrics and Gynecology, Southern Illinois University. All 15 OB/GYN residents were enrolled in this course as part of their educational curriculum. First, face-to-face instructions were given in detail about the blended learning process, course content, and online website. The residents were then assigned tasks related to completing the online component of the course, including watching multimedia presentations, reading the resources placed online, and participating in online asynchronous discussions. The course culminated with a face-to-face session to clarify misconceptions. Pre- and postcourse quizzes were administered to the residents to assess their retention and understanding. Outcome Objective analysis demonstrated significant improvements in retention and understanding after participating in the course. The blended learning format was well received by the residents.

We implemented the portfolio format in November 2012, and the evaluations from the students have shown that the format is good; the students get less stressed at the exam......In Denmark the Biomedical Laboratory Scientist programme lasts for 3½ years, divided into 14 modules of 10 weeks. Every module concludes with an exam, which can be very stressful for the students. A survey was made among the students, confirming this. How can we change some of the exams in order...... to minimize the students' stress level? Then the pedagogical considerations started – where and how to do this? The conclusion was to work with the portfolio format at module 6 and module 7 and make it the exam form, as it was possible to divide the expected learning outcome for the two modules into topics...

    To characterize the nature of surgical preparation among otolaryngology residents nationwide, determine the self-rated effectiveness and efficiency of case preparation practices, and identify potential means for educational improvement. A survey examining the study objectives was developed and distributed to otolaryngology residents nationwide. Survey response data were submitted to descriptive analysis and comparative analyses between junior and senior residents. Literature regarding case preparation among otolaryngology residents was reviewed. Among 108 resident respondents, the most commonly used resources included textbooks (86.1%), surgical education websites (74.1%), and surgical atlases (66.7%). Time was the primary limitation (cited by 84.3%) and convenience the predominant factor influencing resource selection (92.5%). On a 5-point Likert scale, mean scores regarding effectiveness and efficiency of case preparation were 3.53 ± 0.68 and 3.19 ± 0.88, respectively. Senior residents compared to junior residents were more likely to rate their preparation as effective (3.75 ± 0.54 vs 3.40 ± 0.72, P = .008) and efficient (3.45 ± 0.85 vs 3.03 ± 0.86, P = .02). Otolaryngology residents do not consistently rate their case preparation as effective or efficient. While there appears to be progress in self-directed learning throughout residency, room for improvement remains, with potential avenues for such improvement explored here.

    Lifelong learning is an integral component of practice-based learning and improvement. Physicians need to be lifelong learners to provide timely, efficient, and state-of-the-art patient care in an environment where knowledge, technology, and social requirements are rapidly changing. To assess graduates' self-reported perception of the usefulness of a residency program requirement to submit a narrative report describing their planned educational modalities for their future continued medical learning ("Education for Life" requirement), and to compare the modalities residents intended to use with their reported educational activities. Data was compiled from the Education for Life reports submitted by internal medicine residents at the University of Tennessee College of Medicine Chattanooga from 1998 to 2000, and from a survey sent to the same 27 graduates 2 to 4 years later from 2000 to 2004. Twenty-four surveys (89%) were returned. Of the responding graduates, 58% (14/24) found the Education for Life requirement useful for their future continued medical learning. Graduates intended to keep up with a mean of 3.4 educational modalities, and they reported keeping up with 4.2. In a multivariable analysis, the number of modalities graduates used was significantly associated with the number they had planned to use before graduation (P  =  .04) but not with their career choice of subspecialization. The majority of residents found the Education for Life requirement useful for their future continued medical learning. Graduates, regardless of specialty, reported using more modalities for continuing their medical education than they thought they would as residents. Considering lifelong learning early in training and then requiring residents to identify ways to practice lifelong learning as a requirement for graduation may be dispositive.

    Organizational effects on job satisfaction, burnout, work-life balance, and perceived support have not been studied in the context of the clinical learning environment. We evaluated the relationship between academic resources and resident well-being, the clinical learning environment, and in-service examination performance of surgical residents. Residents of general surgery and surgical specialty programs were recruited from March 2016 through June 2016 across the Southeast, Mid-Atlantic, and Northeast regions. Program directors were asked to allow distribution of a paper survey or to forward an electronic survey link onto residents. Five dichotomous questions were asked regarding access to academic resources. Validated measures were obtained assessing resident well-being and perceived clinical learning environment. Data were analyzed through t-tests and chi-squared test of independence. We received 276 respondents across 50 programs. Residents perceiving adequate support to succeed had less burnout (P = 0.008), better resilience (P = 0.009), better job satisfaction (P workplace climate (P < 0.001), better organizational support (P < 0.001), and were more likely to have high performance on the in-service examination (P = 0.001). Specific resources including educational stipends, review questions, in-service board prep, and support for poor performers correlated with improved well-being and perceived clinical learning environment. Provision of academic resources has implications beyond in-service examination performance, correlating with improved resident well-being and perceptions of the clinical learning environment.

    The aim of the present study was to establish correlations between the dimensions of clinical learning environments (ACA) considering variables like: health institutions, hospital offices, specialty, and year of residency. 4,189 doctors were evaluated through an online survey in 2012. The results revealed that the dimension of "educational processes" correlated best with others; specialties with the best ACA from the view of the medical residents were Internal Medicine and Surgery; and the third year residents had less favorable perceptions of their ACA. The pursuance of the academic program is relevant to physicians in training and teachers play an important role in the educational process.

    Full Text Available Over recent decades, the use of portfolios in medical education has evolved, and is being applied in undergraduate and postgraduate programs worldwide. Portfolios, as a learning process and method of documenting and assessing learning, is supported as a valuable tool by adult learning theories that stress the need for learners to be self-directed and to engage in experiential learning. Thoughtfully implemented, a portfolio provides learning experiences unequaled by any single learning tool. The credibility (validity and dependability (reliability of assessment through portfolios have been questioned owing to its subjective nature; however, methods to safeguard these features have been described in the literature. This paper discusses some of this literature, with particular attention to the role of portfolios in relation to self-reflective learning, provides an overview of current use of portfolios in undergraduate medical education in Saudi Arabia, and proposes research-based guidelines for its implementation and other similar contexts.

    Full Text Available Purpose: No study had been conducted to assess the hospitals’ environment for learning purposes in multicenter sites in Saudi Arabia. It aims to evaluate the environment of hospitals for learning purposes of pediatric residents. Methods: We applied Postgraduate Hospital Educational Environment Measure (PHEEM to measure the learning environment at six teaching hospitals in the Eastern Region of Saudi Arabia from September to December 2013. Results: The number of respondents was 104 (86.7% out of 120 residents and 37 females and 67 male residents have responded. The residents’ response scored 100 out of 160 maximum score in rating of PHEEM that showed overall learning environment is favorable for training. There were some items in the social support domain suggesting improvements. There was no significant difference between male and female residents. There was a difference among the participant teaching hospitals (p<0.05. Conclusion: The result pointed an overall positive rating. Individual item scores suggested that their social life during residency could be uninspiring. They have the low satisfactory level and they feel racism, and sexual discrimination. Therefore, there is still a room for improvement.

    Few information are available regarding the learning curve in ultrasonography and even less for ultrasound-guided regional anesthesia. This study aimed to evaluate in a training program the learning curve on a phantom of 12 residents novice in ultrasonography. Twelve trainees inexperienced in ultrasonography were given introductory training consisting of didactic formation on the various components of the portable ultrasound machine (i.e. on/off button, gain, depth, resolution, and image storage). Then, students performed three trials, in two sets of increased difficulty, at executing these predefined tasks: adjustments of the machine, then localization of a small plastic piece introduced into roasting pork (3 cm below the surface). At the end of the evaluation, the residents were asked to insert a 22 G needle into an exact predetermined target (i.e. point of fascia intersection). The progression of the needle was continuously controlled by ultrasound visualization using injection of a small volume of water (needle perpendicular to the longitudinal plane of the ultrasound beam). Two groups of two different examiners evaluated for each three trials the skill of the residents (quality, time to perform the machine adjustments, to localize the plastic target, and to hydrolocalize, and volume used for hydrolocalization). After each trial, residents evaluated their performance using a difficulty scale (0: easy to 10: difficult). All residents performed the adjustments from the last trial of each set, with a learning curve observed in terms of duration. Localization of the plastic piece was achieved by all residents at the 6th trial, with a shorter duration of localization. Hydrolocalization was achieved after the 4th trial by all subjects. Difficulty scale was correlated to the number of trials. All these results were independent of the experience of residents in regional anesthesia. Four trials were necessary to adjust correctly the machine, to localize a target, and to

    Lumbar puncture (LP) is an essential part of adult neurology residency training. Technologic as well as nontechnologic training is needed. However, current assessment tools mostly focus on the technologic aspects of LP. We propose a training method-problem- and simulator-based learning (PSBL)-in LP residency training to develop overall skills of neurology residents. We enrolled 60 neurology postgraduate-year-1 residents from our standardized residents training center and randomly divided them into 2 groups: traditional teaching group and PSBL group. After training, we assessed the extent that the residents were ready to perform LP and tracked successful LPs performed by the residents. We then asked residents to complete questionnaires about the training models. Performance scores and the results of questionnaires were compared between the 2 groups. Students and faculty concluded that PSBL provided a more effective learning experience than the traditional teaching model. Although no statistical difference was found in the pretest, posttest, and improvement rate scores between the 2 groups, based on questionnaire scores and number of successful LPs after training, the PSBL group showed a statistically significant improvement compared with the traditional group. Findings indicated that nontechnical elements, such as planning before the procedure and controlling uncertainties during the procedure, are more crucial than technical elements. Compared with traditional teaching model, PSBL for LP training can develop overall surgical skills, including technical and nontechnical elements, improving performance. Residents in the PSBL group were more confident and effective in performing LP. Copyright © 2017 Elsevier Inc. All rights reserved.

    Resident physicians' scores on the REI section of the CREOG exam are traditionally low, and nearly 40% of house staff nation-wide perceive their REI knowledge to be poor. We aimed to assess whether an interactive case-based group-learning curriculum would narrow the REI knowledge gap by improving understanding and retention of core REI concepts under the time constraints affecting residents. A three-hour case-based workshop was developed to address four primary CREOG objectives. A multiple-choice test was administered immediately before and after the intervention and 7 weeks post-workshop, to evaluate both knowledge and confidence. Following the intervention, residents self-reported increased confidence with counseling and treatment of PCOS, ovulation induction cycle monitoring, counseling and treatment of POI, and breaking bad news related to infertility (p < 0.05). The multiple-choice exam was re-administered 7 weeks post-intervention, and scores remained significantly improved compared to pre-workshop scores (p < 0.05). At that time, all residents either strongly agreed (91.7%) or agreed (8.3%) that the case-based interactive format was preferable to traditional lecture-based teaching. In conclusion, a nontraditional curriculum aimed at teaching core REI concepts to residents through interactive case-based learning can be successfully integrated into a residency curriculum, and significantly improves knowledge and confidence of critical concepts in REI.

    To evaluate pharmacy students' perceived benefits of the portfolio process and to gather suggestions for improving the process. A questionnaire was designed and administered to 250 first-, second-, and third-year pharmacy students at the University of Arizona College of Pharmacy. Although the objectives of the portfolio process were for students to understand the expected outcomes, understand the impact of extracurricular activities on attaining competencies, identify what should be learned, identify their strengths and weaknesses, and modify their approach to learning, overall students perceived the portfolio process as having less than moderate benefit. First-year students wanted more examples of portfolios while second- and third-year students suggested that more time with their advisor would be beneficial. The portfolio process will continue to be refined and efforts made to improve students' perceptions of the process as it is intended to develop the self-assessments skills they will need to improve their knowledge and professional skills throughout their pharmacy careers.

    The consensus about the importance of communication skills in patient-care does not guarantee that students and faculty perceive the usefulness of these skills. This study evaluated and compared medical students', residents' and tutors' attitudes towards learning communication skills, and examined the association with gender and year of residency. We conducted a cross-sectional survey with 492 participants (282 second-year students, 131 residents and 79 tutors). They completed the Communication Skills Attitude Scale (CSAS) and demographic/educational information. In general, participants showed positive attitudes towards learning communication skills. Medical students, residents and tutors did not differ on the Positive Attitudes Scale (CSAS-PAS). Residents scored higher than medical students on the Negative Attitudes Scale (CSAS-NAS) (P communication skills an essential component for clinical practice and they agree about the need to learn these communication skills. Attention should be paid to measuring attitudes at all three levels of medical education in the design of communication skills courses.

    Mobile learning enables users to interact with educational resources while in variable locations. Medical students in residency positions need to assimilate considerable knowledge besides their practical training and we therefore aimed to evaluate the impact of using short message service via cell phone as a learning tool in residents of Obstetrics and Gynecology in our hospital. We sent short messages including data about breast cancer to the cell phones of 25 residents of gynecology and obstetrics and asked them to study a well-designed booklet containing another set of information about the disease in the same period. The rate of learning derived from the two methods was compared by pre- and post-tests and self-satisfaction assessed by a relevant questionnaire at the end of the program. The mobile learning method had a significantly better effect on learning and created more interest in the subject. Learning via receiving SMS can be an effective and appealing method of knowledge acquisition in higher levels of education.

    Full Text Available Abstract Background Journal clubs are an internationally recognized teaching tool in many postgraduate medical education fields. In developing countries lack of funds for current print materials may have limited journal club use. But with advancing information technology trainees in developing countries increasingly have more access to high quality journals online. However, we are aware of no studies describing journal club existence and effectiveness in postgraduate medical training in Pakistan. Also we have found no published effectiveness studies of this teaching modality in Community Medicine (Public Health in any country. This study evaluated the effectiveness of Community Medicine (Public Health Resident Journal Club (CMR-JC in Aga Khan University, Pakistan using international criteria for successful journal clubs (2 years continuous existence and more than 50% attendance and examining resident and alumni satisfaction. Methods Journal club effectiveness criteria were searched using electronic search databases. Departmental records were reviewed from September1999–September 2005. Ninety percent of residents and alumni of Community Medicine Residency Programme participated voluntarily in a confidential survey. Results The CMR-JC was regularly conducted. More than 95% of residents attended. (Total residents in the CMR-Programme: 32. Twenty-seven out of 29 current residents/alumni responded to the anonymous questionnaire. Acquisition of critical appraisal skills (23 respondents and keeping up with current literature (18 respondents were the two most important objectives achieved. Respondents recommended improved faculty participation and incorporating a structured checklist for article review. Conclusion CMR-JC fulfils criteria for effective journal clubs. Residents and alumni agree CMR-JC meets its objectives. Incorporating suggested recommendations will further improve standards. The journal club learning modality should be included in

    Purpose: Medical Physicists and Radiation Oncologists are two professions who should be working as a team for optimal patient care, yet lack of mutual understanding about each others respective role and work environment creates barriers To improve collaboration and learning, we designed a shared didactic and work space for physics and radiation oncology residents to maximize interaction throughout their professional training. Methods: Physician and Physics residents are required to take the same didactic classes, including journal clubs and respective seminars. The residents also share an office environment among the seven physician and two physic residents. Results: By maximizing didactic overlap and sharing office space, the two resident groups have developed a close professional relationship and supportive work environment. Several joint research projects have been initiated by the residents. Awareness of physics tasks in the clinic has led to a request by the physician residents to change physics didactics, converting the physics short course into a lab-oriented course for the medical residents which is in part taught by the physics residents. The physics seminar is given by both residency groups; increased motivation and interest in learning about physics has led to several medical resident-initiated topic selections which generated lively discussion. The physics long course has changed toward including more discussion among residents to delve deeper into topics and study beyond what passing the boards would require. A supportive work environment has developed, embedding the two physics residents into a larger residents group, allowing them to find mentor and peers more easily. Conclusion: By creating a shared work and didactic environment, physician and physics residents have improved their understanding of respective professional practice. Resident-initiated changes in didactic practice have led to improved learning and joint research. A strong social

    Faced with work-hour restrictions, educators are mandated to improve the efficiency of resident and medical student education. Few studies have assessed learning styles in medicine; none have compared teaching and learning preferences. Validated tools exist to study these deficiencies. Kolb describes 4 learning styles: converging (practical), diverging (imaginative), assimilating (inductive), and accommodating (active). Grasha Teaching Styles are categorized into "clusters": 1 (teacher-centered, knowledge acquisition), 2 (teacher-centered, role modeling), 3 (student-centered, problem-solving), and 4 (student-centered, facilitative). Kolb's Learning Style Inventory (HayGroup, Philadelphia, Pennsylvania) and Grasha-Riechmann's TSS were administered to surgical faculty (n = 61), residents (n = 96), and medical students (n = 183) at a tertiary academic medical center, after informed consent was obtained (IRB # 06-0612). Statistical analysis was performed using χ(2) and Fisher exact tests. Surgical residents preferred active learning (p = 0.053), whereas faculty preferred reflective learning (p style more often than surgical faculty (p = 0.01). Medical students preferred converging learning (42%) and cluster 4 teaching (35%). Statistical significance was unchanged when corrected for gender, resident training level, and subspecialization. Significant differences exist between faculty and residents in both learning and teaching preferences; this finding suggests inefficiency in resident education, as previous research suggests that learning styles parallel teaching styles. Absence of a predominant teaching style in residents suggests these individuals are learning to be teachers. The adaptation of faculty teaching methods to account for variations in resident learning styles may promote a better learning environment and more efficient faculty-resident interaction. Additional, multi-institutional studies using these tools are needed to elucidate these findings fully

    E-learning, in its most rudimentary form, is the use of Internet-based resources for teaching and learning purposes. In surgical specialties, this definition encompasses the use of virtual patient cases, digital modeling, and online tutorials, as well as standardized video and imaging. As new technological frontiers rapidly emerge within otolaryngology, e-learning may be an effective alternative to traditional teaching. Here we present a systematic review of the literature assessing the efficacy of e-learning for otolaryngology education and a discussion of the relevance of these programs for both medical students and residents within the field. Systematic review. A systematic search of PubMed, Embase, Web of Science, and the Cochrane Library was conducted according to the guidelines defined in the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. Twelve studies met inclusion criteria. These studies measured a range of outcomes from basic science anatomical knowledge to clinically relevant endpoints such as diagnostic accuracy. Nearly all of the studies reported greater satisfaction and/or significantly increased objective knowledge using the e-learning intervention compared to traditional techniques. E-learning proves to be a powerful alternative to standard teaching techniques within otolaryngology education for both residents and medical students. Future work should focus on validating specific e-learning programs and accessing long-term knowledge retention using these innovative platforms.

    2015-01-01

    There is a growing body of literature that suggests that learners assimilate information differently, depending on their preferred learning style. The VARK model categorizes learners as visual (V), aural (A), read/write (R), kinesthetic (K), or multimodal (MM). We hypothesized that resident VARK learning style preferences and American Board of Surgery In-Training Examination (ABSITE) performance are associated. The Fleming VARK learning styles inventory was administered to all general surgery residents at a university hospital-based program each year to determine their preferred learning style. Resident scores from the 2012 and 2013 ABSITE were examined to identify any correlation with learning style preferences. Over a 2-year period, residents completed 53 VARK inventory assessments. Most (51%) had a multimodal preference. Dominant aural and read/write learners had the lowest and highest mean ABSITE scores, respectively (p = 0.03). Residents with dominant read/write learning preferences perform better on the ABSITE than their peers did, whereas residents with dominant aural learning preferences underperform on the ABSITE. This may reflect an inherent and inadvertent bias of the examination against residents who prefer to learn via aural modalities. Copyright © 2015 Association of Program Directors in Surgery.

    Full text: The comprehensive evaluation of medical residents in a residency-training program includes the use of educational tools to measure the attainment of competencies in the cognitive, psychomotor and affective domains as prescribed in the training curriculum. Attention is almost always focused on the testing of cognitive domain of the learners with limited attention given on the psychomotor and affective parameters, which are in fact, together with the cognitive domain, integral to the students' learning behaviour. This paper aims to review the principles of test construction, including the perspectives on the roles, types and purpose of tests in the domains of learning (cognitive, psychomotor and affective) as well as the use of Non-Test materials for measuring affective learning outcomes and the construction of Performance Tests and Portfolio Assessment tools which are all essential for the effective and efficient evaluation of residents in a Nuclear Medicine Training Program.

    In medical education, students need to acquire skills to self-direct(ed) learning (SDL), to enable their development into self-directing and reflective professionals. This study addressed the mentor perspective on how processes in the mentor-student interaction influenced development of SDL. n = 22 mentors of a graduate-entry medical school with a problem-based curriculum and longitudinal mentoring system were interviewed (n = 1 recording failed). Using activity theory (AT) as a theoretical framework, thematic analysis was applied to the interview data to identify important themes. Four themes emerged: centered around the role of the portfolio, guiding of students' SDL in the context of assessment procedures, mentor-role boundaries and longitudinal development of skills by both the mentor and mentee. Application of AT showed that in the interactions between themes tensions or supportive factors could emerge for activities in the mentoring process. The mentors' perspective on coaching and development of reflection and SDL of medical students yielded important insights into factors that can hinder or support students' SDL, during a longitudinal mentor-student interaction. Coaching skills of the mentor, the interaction with a portfolio and the context of a mentor community are important factors in a longitudinal mentor-student interaction that can translate to students' SDL skills.

    Full Text Available Portfolios have been used in the medical curriculum to evaluate difficult-to-assess areas such as students' attitudes, professionalism and teamwork. However, their use early in a problem-based learning (PBL course to foster deep learning and enhance students' self-directed learning has not been adequately studied. The aims of this paper are to: (1 understand the uses of portfolios and the rationale for using reflection in the early years of a PBL curriculum; (2 discuss how to introduce portfolios and encourage students' critical thinking skills, not just reflection; and (3 provide students with tips that could enhance their skills in constructing good portfolios.

    Learning styles theory posits that learners have distinct preferences for how they assimilate new information. The VARK model categorizes learners based on combinations of 4 learning preferences: visual (V), aural (A), read/write (R), and kinesthetic (K). A previous single institution study demonstrated that the VARK preferences of applicants who interview for general surgery residency are different from that of the general population and that learning preferences were associated with performance on standardized tests. This multiinstitutional study was conducted to determine the distribution of VARK preferences among interviewees for general surgery residency and the effect of those preferences on United States Medical Licensing Examination (USMLE) scores. The VARK learning inventory was administered to applicants who interviewed at 3 general surgery programs during the 2014 to 2015 academic year. The distribution of VARK learning preferences among interviewees was compared with that of the general population of VARK respondents. Performance on USMLE Step 1 and Step 2 Clinical Knowledge was analyzed for associations with VARK learning preferences. Chi-square, analysis of variance, and Dunnett's test were used for statistical analysis, with p learning modality. The distribution of VARK preferences of interviewees was different than that of the general population (p = 0.02). By analysis of variance, there were no overall differences in USMLE Step 1 and Step 2 Clinical Knowledge scores by VARK preference (p = 0.06 and 0.21, respectively). However, multiple comparison analysis using Dunnett's test revealed that interviewees with R preferences had significantly higher scores than those with multimodal preferences on USMLE Step 1 (239 vs. 222, p = 0.02). Applicants who interview for general surgery residency have a different pattern of VARK preferences than that of the general population. Interviewees with preferences for read/write learning modalities have higher scores

    The subconscious way in which an individual approaches learning, goal orientation (GO), has been shown to influence job satisfaction, job performance, and burnout in nonmedical cohorts. The aim of this study was to adapt and validate an instrument to assess GO in surgical residents, so that in the future, we can better understand how differences in motivation affect professional development. Residents were recruited to complete a 17-item survey adapted from the Patterns of Adaptive Learning Scales (PALS). The survey included three scales assessing GO in residency-specific terms. Items were scored on a 5-point Likert scale, and the psychometric properties of the adapted and original PALS were compared. Ninety-five percent of residents (61/64) participated. Median age was 30 y and 33% were female. Mean (standard deviation) scale scores for the adapted PALS were: mastery 4.30 (0.48), performance approach (PAP) 3.17 (0.99), and performance avoid 2.75 (0.88). Mean (standard deviation) scale scores for the original PALS items were: mastery 3.35 (1.02), PAP 2.76 (1.15), and performance avoid 2.41 (0.91). Cronbach alpha were α = 0.89 and α = 0.84 for the adapted PAP and avoid scales, respectively, which were comparable with the original scales. For the adapted mastery scale, α = 0.54. Exploratory factor analysis revealed five factors, and factor loadings for individual mastery items did not load consistently onto a single factor. This study represents the first steps in the development of a novel tool to measure GO among surgical residents. Understanding motivational psychology in residents may facilitate improved education and professional development. Copyright © 2014 Elsevier Inc. All rights reserved.

    Full Text Available Competency-based education is a resurgent paradigm in professional medical education. However, more specific knowledge is needed about the learning process of such competencies, since they consist of complex skills. We chose to focus on the competency of skilled communication and want to further explore its learning process, since it is regarded as a main competency in medical education.This study aims to explore in more detail the learning process that residents in general practice go through during workplace-based learning in order to become skilled communicators.A qualitative study was conducted in which twelve GP residents were observed during their regular consultations, and were interviewed in-depth afterwards.Analysis of the data resulted in the construction of five phases and two overall conditions to describe the development towards becoming a skilled communicator: Confrontation with (undesired behaviour or clinical outcomes was the first phase. Becoming conscious of one's own behaviour and changing the underlying frame of reference formed the second phase. The third phase consisted of the search for alternative behaviour. In the fourth phase, personalization of the alternative behaviour had to occur, this was perceived as difficult and required much time. Finally, the fifth phase concerned full internalization of the new behaviour, which by then had become an integrated part of the residents' clinical repertoire. Safety and cognitive & emotional space were labelled as overall conditions influencing this learning process.Knowledge and awareness of these five phases can be used to adjust medical working and learning environments in such a way that development of skilled medical communication can come to full fruition and its benefits are more fully reaped.

    The Department of Dental Medicine of Lutheran Medical Center has developed an asynchronous online curriculum consisting of prerecorded PowerPoint presentations with audio explanations. The focus of this study was to evaluate if the new asynchronous format satisfied the educational needs of the residents compared to traditional lecture (face-to-face) and synchronous (distance learning) formats. Lectures were delivered to 219 dental residents employing face-to-face and synchronous formats, as well as the new asynchronous format; 169 (77 percent) participated in the study. Outcomes were assessed with pretests, posttests, and individual lecture surveys. Results found the residents preferred face-to-face and asynchronous formats to the synchronous format in terms of effectiveness and clarity of presentations. This preference was directly related to the residents' perception of how well the technology worked in each format. The residents also rated the quality of student-instructor and student-student interactions in the synchronous and asynchronous formats significantly higher after taking the lecture series than they did before taking it. However, they rated the face-to-face format as significantly more conducive to student-instructor and student-student interaction. While the study found technology had a major impact on the efficacy of this curricular model, the results suggest that the asynchronous format can be an effective way to teach a postgraduate course.

    2016-09-01

    In this paper, we present an end-to-end approach that employs machine learning techniques and Ontology-based Bayesian Networks (BN) to characterize the behavior of resident space objects. State-of-the-Art machine learning architectures (e.g. Extreme Learning Machines, Convolutional Deep Networks) are trained on physical models to learn the Resident Space Object (RSO) features in the vectorized energy and momentum states and parameters. The mapping from measurements to vectorized energy and momentum states and parameters enables behavior characterization via clustering in the features space and subsequent RSO classification. Additionally, Space Object Behavioral Ontologies (SOBO) are employed to define and capture the domain knowledge-base (KB) and BNs are constructed from the SOBO in a semi-automatic fashion to execute probabilistic reasoning over conclusions drawn from trained classifiers and/or directly from processed data. Such an approach enables integrating machine learning classifiers and probabilistic reasoning to support higher-level decision making for space domain awareness applications. The innovation here is to use these methods (which have enjoyed great success in other domains) in synergy so that it enables a "from data to discovery" paradigm by facilitating the linkage and fusion of large and disparate sources of information via a Big Data Science and Analytics framework.

    The Accreditation Council for Graduate Medical Education has begun to evaluate teaching institutions' learning environments with Clinical Learning Environment Review visits, including trainee involvement in institutions' patient safety and quality improvement efforts. We sought to address the dearth of metrics that assess trainee patient safety perceptions of the clinical environment. Using the Hospital Survey on Patient Safety Culture (HSOPSC), we measured resident and fellow perceptions of patient safety culture in 50 graduate medical education programs at 10 hospitals within an integrated health system. As institution-specific physician scores were not available, resident and fellow scores on the HSOPSC were compared with national data from 29 162 practicing providers at 543 hospitals. Of the 1337 residents and fellows surveyed, 955 (71.4%) responded. Compared with national practicing providers, trainees had lower perceptions of patient safety culture in 6 of 12 domains, including teamwork within units, organizational learning, management support for patient safety, overall perceptions of patient safety, feedback and communication about error, and communication openness. Higher perceptions were observed for manager/supervisor actions promoting patient safety and for staffing. Perceptions equaled national norms in 4 domains. Perceptions of patient safety culture did not improve with advancing postgraduate year. Trainees in a large integrated health system have variable perceptions of patient safety culture, as compared with national norms for some practicing providers. Administration of the HSOPSC was feasible and acceptable to trainees, and may be used to track perceptions over time.

    The optimization of large portfolios displays an inherent instability due to estimation error. This poses a fundamental problem, because solutions that are not stable under sample fluctuations may look optimal for a given sample, but are, in effect, very far from optimal with respect to the average risk. In this paper, we approach the problem from the point of view of statistical learning theory. The occurrence of the instability is intimately related to over-fitting, which can be avoided using known regularization methods. We show how regularized portfolio optimization with the expected shortfall as a risk measure is related to support vector regression. The budget constraint dictates a modification. We present the resulting optimization problem and discuss the solution. The L2 norm of the weight vector is used as a regularizer, which corresponds to a diversification 'pressure'. This means that diversification, besides counteracting downward fluctuations in some assets by upward fluctuations in others, is also crucial because it improves the stability of the solution. The approach we provide here allows for the simultaneous treatment of optimization and diversification in one framework that enables the investor to trade off between the two, depending on the size of the available dataset.

    ECG interpretation is a pivotal skill to acquire during residency, especially for Emergency Department (ED) residents. Previous studies reported that ECG interpretation competency among residents was rather low. However, the optimal resource to improve ECG interpretation skills remains unclear. The aim of our study was to compare two teaching modalities to improve the ECG interpretation skills of ED residents: e-learning and lecture-based courses. The participants were first-year and second-year ED residents, assigned randomly to the two groups. The ED residents were evaluated by means of a precourse test at the beginning of the study and a postcourse test after the e-learning and lecture-based courses. These evaluations consisted of the interpretation of 10 different ECGs. We included 39 ED residents from four different hospitals. The precourse test showed that the overall average score of ECG interpretation was 40%. Nineteen participants were then assigned to the e-learning course and 20 to the lecture-based course. Globally, there was a significant improvement in ECG interpretation skills (accuracy score=55%, P=0.0002). However, this difference was not significant between the two groups (P=0.14). Our findings showed that the ECG interpretation was not optimal and that our e-learning program may be an effective tool for enhancing ECG interpretation skills among ED residents. A large European study should be carried out to evaluate ECG interpretation skills among ED residents before the implementation of ECG learning, including e-learning strategies, during ED residency.

    To identify residents' perceived barriers to learning phacoemulsification surgical procedures and to evaluate whether virtual reality simulation training changed these perceptions. The ophthalmology residents undertook a simulation phacoemulsification course and proficiency assessment on the Eyesi system using the previously validated training modules of intracapsular navigation, anti-tremor, capsulorrhexis, and cracking/chopping. A cross-sectional, multicenter survey on the perceived difficulties in performing phacoemulsification tasks on patients, based on the validated International Council of Ophthalmology's Ophthalmology Surgical Competency Assessment Rubric (ICO-OSCAR), using a 5-point Likert scale (1 = least and 5 = most difficulty), was conducted among residents with or without prior simulation training. Mann-Whitney U tests were carried out to compare the mean scores, and multivariate regression analyses were performed to evaluate the association of lower scores with the following potential predictors: 1) higher level trainee, 2) can complete phacoemulsification most of the time (>90%) without supervisor's intervention, and 3) prior simulation training. The study was conducted in ophthalmology residency training programs in five regional hospitals in Hong Kong. Of the 22 residents, 19 responded (86.3%), of which 13 (68.4%) had completed simulation training. Nucleus cracking/chopping was ranked highest in difficulty by all respondents followed by capsulorrhexis completion and nucleus rotation/manipulation. Respondents with prior simulation training had significantly lower difficulty scores on these three tasks (nucleus cracking/chopping 3.85 vs 4.75, P = 0.03; capsulorrhexis completion 3.31 vs 4.40, P = 0.02; and nucleus rotation/manipulation 3.00 vs 4.75, P = 0.01). In multivariate analyses, simulation training was significantly associated with lower difficulty scores on these three tasks. Residents who had completed Eyesi simulation training had higher

    Past didactic pedagogy on biomedical research ethics and informed consent in our program had resulted in passive memorization of information and disengaged learning within psychiatry residents and clinical researchers. The question is how do we better motivate and engage learners within the session. Thus, we incorporated narratives into the learning environment and hypothesised that the use of narratives in the teaching of biomedical research ethics and informed consent would be associated with greater engagement, motivation, understanding, reflective learning and effectiveness of the teaching session. The narratives were chosen from the history of research ethics and the humanities literature related to human subject research. Learners were asked to provide post-session feedback through an anonymised questionnaire on their learning session. An outcomes logic model was used for assessment with focus on immediate outcomes such as engagement, motivation, understanding and reflective learning. Overall, 70.5% (N = 273) of the learners responded to the questionnaire. Amongst the respondents, 92.6% (N = 253) of the participants ranked use of narratives as most helpful in appreciating the historical context of research ethics and informed consent in research. The majority felt engaged (89.8%, N = 245), more motivated to learn (77.5%, N = 212) and better equipped (86.4%, N = 236) about the subject matter. Better appreciation of the learning topic, engagement, motivation to learn, equipping were strongly correlated with the promotion of reflective learning, effectiveness of teaching, promotion of critical thinking and overall positive rating of the teaching session on research ethics (all p ethics and informed consent, and address underlying motivational factors behind learning and understanding of research ethics.

    Successful resuscitation of a pregnant woman undergoing cardiac arrest and survival of the fetus require prompt, high-quality cardiopulmonary resuscitation. The objective of this observational study was to assess management of maternal cardiac arrest by anesthesia residents using high-fidelity simulation and compare subsequent performance following either didactic teaching or electronic learning (e-learning). Twenty anesthesia residents were randomized to receive either didactic teaching (Didactic group, n = 10) or e-learning (Electronic group, n = 10) on maternal cardiac arrest. Baseline management skills were tested using high-fidelity simulation, with repeat simulation testing one month after their teaching intervention. The time from cardiac arrest to start of perimortem Cesarean delivery (PMCD) was measured, and the technical and nontechnical skills scores between the two teaching groups were compared. The median [interquartile range] time to PMCD decreased after teaching, from 4.5 min [3.4 to 5.1 min] to 3.5 min [2.5 to 4.0 min] (P = 0.03), although the change within each group was not statistically significant (Didactic group 4.9 to 3.8 min, P = 0.2; Electronic group 3.9 to 2.5 min, P = 0.07; Didactic group vs Electronic group, P = 1.0). Even after teaching, only 65% of participants started PMCD within four minutes. Technical and nontechnical skills scores improved after teaching in both groups, and there were no differences between the groups. There are gaps in the knowledge and implementation of resuscitation protocols and the recommended modifications for pregnancy among residents. Teaching can improve performance during management of maternal cardiac arrest. Electronic learning and didactic teaching offer similar benefits.

    Introduction. Web-based learning (WBL) is increasingly used in medical education; however, residency training programs often lack guidance on its implementation. We describe how the use of feasibility studies can guide the use of WBL in anesthesia residency training. Methods. Two case-based WBL emergency airway management modules were developed for self-directed use by anesthesia residents. The feasibility of using this educational modality was assessed using a single cohort pretest/posttest design. Outcome measures included user recruitment and retention rate, perceptions of educational value, and knowledge improvement. The differences between pre- and postmodule test scores and survey Likert scores were analysed using the paired t test. Results. Recruitment and retention rates were 90% and 65%, respectively. User-friendliness of the modules was rated highly. There was a significant improvement in perceptions of the value of WBL in the postsurvey. There was a significant knowledge improvement of 29% in the postmodule test. Conclusions. Feasibility studies can help guide appropriate use of WBL in curricula. While our study supported the potential feasibility of emergency airway management modules for training, collaboration with other anesthesia residency programs may enable more efficient development, implementation, and evaluation of this resource-intensive modality in anesthesia education and practice.

    An inherent tension exists in clinical training between supervising learners to ensure quality and patient safety, and allowing learners to practice independently to gain experience. In this issue of Academic Medicine, Biondi and colleagues discuss this tension, highlighting the disconnect between faculty and resident perceptions of autonomous practice for housestaff. They report that each group perceives itself as more competent in its role than does the other group. Their work leads us to consider how medical educators might safely and effectively transform the learning process. Self-determination theory (SDT) holds that there is a human tendency to develop toward self-directed and autonomous regulation of behavior. This development of intrinsic motivation is governed by the complex relationships among autonomy, competence, and relatedness as well as educational content and the learning milieu. Applying an SDT framework to their findings, Biondi and colleagues report that faculty desire from residents the evidence of internal motivation and demonstration of competence and self-confidence that will allow faculty to entrust learners with autonomy. They conclude, however, that these are qualities that faculty find lacking in many residents. To optimize the balance between autonomy and supervision, this Commentary's author proposes the use of "scaffolding," a construct from developmental psychology. In the scaffolding model, the role of teachers is to support the learner's development and to provide support structures to help the learner get to the next stage of entrustment and competence. Achieving a balance is essential to providing the best patient care now and in the future.

    We consider the problem of concurrent portfolio losses in two non-overlapping credit portfolios. In order to explore the full statistical dependence structure of such portfolio losses, we estimate their empirical pairwise copulas. Instead of a Gaussian dependence, we typically find a strong asymmetry in the copulas. Concurrent large portfolio losses are much more likely than small ones. Studying the dependences of these losses as a function of portfolio size, we moreover reveal that not only large portfolios of thousands of contracts, but also medium-sized and small ones with only a few dozens of contracts exhibit notable portfolio loss correlations. Anticipated idiosyncratic effects turn out to be negligible. These are troublesome insights not only for investors in structured fixed-income products, but particularly for the stability of the financial sector. JEL codes: C32, F34, G21, G32, H81.

    Midwives are required to maintain a professional portfolio as part of their statutory requirements. Some midwives are using open social networking tools and processes to develop an e-portfolio. However, confidentiality of patient and client data and professional reputation have to be taken into consideration when using online public spaces for reflection. There is little evidence about how midwives use social networking tools for ongoing learning. It is uncertain how reflecting in an e-portfolio with an audience impacts on learning outcomes. This paper investigates ways in which reflective midwifery practice be carried out using e-portfolio in open, social networking platforms using collaborative processes. Using an auto-ethnographic approach I explored my e-portfolio and selected posts that had attracted six or more comments. I used thematic analysis to identify themes within the textual conversations in the posts and responses posted by readers. The analysis identified that my collaborative e-portfolio had four themes: to provide commentary and discuss issues; to reflect and process learning; to seek advice, brainstorm and process ideas for practice, projects and research, and provide evidence of professional development. E-portfolio using open social networking tools and processes is a viable option for midwives because it facilitates collaborative reflection and shared learning. However, my experience shows that concerns about what people think, and client confidentiality does impact on the nature of open reflection and learning outcomes. I conclude this paper with a framework for managing midwifery statutory obligations using online public spaces and social networking tools. Copyright © 2013 Australian College of Midwives.

    The aim of the study was to ascertain the learning curves for the radiology residents when first introduced to an anatomic structure in magnetic resonance images (MRI) to which they have not been previously exposed to. The iliolumbar ligament is a good marker for testing learning curves of radiology residents because the ligament is not part of a routine lumbar MRI reporting and has high variability in detection. Four radiologists, three residents without previous training and one mentor, studied standard axial T1- and T2-weighted images of routine lumbar MRI examinations. Radiologists had to define iliolumbar ligament while blinded to each other's findings. Interobserver agreement analyses, namely Cohen and Fleiss κ statistics, were performed for groups of 20 cases to evaluate the self-learning curve of radiology residents. Mean κ values of resident-mentor pairs were 0.431, 0.608, 0.604, 0.826, and 0.963 in the analysis of successive groups (P 0.8). Therefore, a junior radiology resident can obtain enough experience in identifying a rather ambiguous anatomic structure in routine MRI after a brief instruction of a few minutes by a mentor and studying approximately 80 cases by oneself. Implementing this methodology will help radiology educators obtain more concrete ideas on the optimal time and effort required for supported self-directed visual learning processes in resident education.

    No scientific assessment of the theoretical teaching of cardiology in France is available. To analyse the impact of the available teaching modalities on the theoretical knowledge of French residents in cardiology. Electronic questionnaires were returned by 283 residents. In the first part, an inventory of the teaching/learning methods was taken, using 21 questions (Yes/No format). The second part was a knowledge test, comprising 15 multiple-choice questions, exploring the core curriculum. Of the 21 variables tested, four emerged as independent predictors of the score obtained in the knowledge test: access to self-assessment (P=0.0093); access to teaching methods other than lectures (P=0.036); systematic discussion about clinical decisions (P=0.013); and the opportunity to prepare and give lectures (P=0.039). The fifth variable was seniority in residency (P=0.0003). Each item of the knowledge test was analysed independently: the score was higher when teaching the item was driven by reading guidelines and was lower if the item had not been covered by the programme (Pcardiology by involving students in the training, by using teaching methods other than lectures and by facilitating access to self-assessment.

    To measure the learning curves of residents in anesthesiology in providing anesthesia for awake craniotomy, and to estimate the case load needed to achieve a "good-excellent" level of competence. Prospective study. Operating room of a university hospital. 7 volunteer residents in anesthesiology. Residents underwent a dedicated training program of clinical characteristics of anesthesia for awake craniotomy. The program was divided into three tasks: local anesthesia, sedation-analgesia, and intraoperative hemodynamic management. The learning curve for each resident for each task was recorded over 10 procedures. Quantitative assessment of the individual's ability was based on the resident's self-assessment score and the attending anesthesiologist's judgment, and rated by modified 12 mm Likert scale, reported ability score visual analog scale (VAS). This ability VAS score ranged from 1 to 12 (ie, very poor, mild, moderate, sufficient, good, excellent). The number of requests for advice also was recorded (ie, resident requests for practical help and theoretical notions to accomplish the procedures). Each task had a specific learning rate; the number of procedures necessary to achieve "good-excellent" ability with confidence, as determined by the recorded results, were 10 procedures for local anesthesia, 15 to 25 procedures for sedation-analgesia, and 20 to 30 procedures for intraoperative hemodynamic management. Awake craniotomy is an approach used increasingly in neuroanesthesia.

    Risk management is very important in portfolio optimization. The mean-variance model has been used in portfolio optimization to minimize the investment risk. The objective of the mean-variance model is to minimize the portfolio risk and achieve the target rate of return. Variance is used as risk measure in the mean-variance model. The purpose of this study is to compare the portfolio composition as well as performance between the optimal portfolio of mean-variance model and equally weighted portfolio. Equally weighted portfolio means the proportions that are invested in each asset are equal. The results show that the portfolio composition of the mean-variance optimal portfolio and equally weighted portfolio are different. Besides that, the mean-variance optimal portfolio gives better performance because it gives higher performance ratio than the equally weighted portfolio.

  7. Minimizing Barriers in Learning for On-Call Radiology Residents-End-to-End Web-Based Resident Feedback System.

    2018-02-01

    Feedback is an essential part of medical training, where trainees are provided with information regarding their performance and further directions for improvement. In diagnostic radiology, feedback entails a detailed review of the differences between the residents' preliminary interpretation and the attendings' final interpretation of imaging studies. While the on-call experience of independently interpreting complex cases is important to resident education, the more traditional synchronous "read-out" or joint review is impossible due to multiple constraints. Without an efficient method to compare reports, grade discrepancies, convey salient teaching points, and view images, valuable lessons in image interpretation and report construction are lost. We developed a streamlined web-based system, including report comparison and image viewing, to minimize barriers in asynchronous communication between attending radiologists and on-call residents. Our system provides real-time, end-to-end delivery of case-specific and user-specific feedback in a streamlined, easy-to-view format. We assessed quality improvement subjectively through surveys and objectively through participation metrics. Our web-based feedback system improved user satisfaction for both attending and resident radiologists, and increased attending participation, particularly with regards to cases where substantive discrepancies were identified.

    The purpose of this report was to describe our experience in planning and developing a portfolio for a clinical clerkship curriculum. We have developed a portfolio for assessing student competency since 2007. During an annual workshop on clinical clerkship curricula, clerkship directors from five Paik hospitals of Inje University met to improve the assessment of the portfolio. We generated templates for students to record their activities and reflection and receive feedback. We uploaded these templates to our school's website for students to download freely. Annually, we have held a faculty development seminar and a workshop for portfolio assessment and feedback. Also, we established an orientation program on how to construct a learning portfolio for students. Future actions include creating a ubiquitous portfolio system, extending the portfolio to the entire curriculum, setting up an advisor system, and managing the quality of the portfolio. This study could be helpful for medical schools that plan to improve their portfolio assessment with an outcome-based approach.

    Portfolios, widely used in undergraduate and postgraduate medicine, have variable purposes, formats and success. A recent systematic review summarised factors necessary for successful portfolio introduction but there are no studies investigating the views of students inexperienced in portfolio use towards portfolio learning. This study's aim was to survey student views about a prospective Professional and Personal Development (PPD) portfolio. This was a qualitative, focus group study. All focus groups were taped and transcribed verbatim, and anonymised. The transcripts were analysed inductively, using framework analysis. Four focus groups were carried out with 32 undergraduate medical students naïve in portfolio use. Three themes relevant to portfolio introduction emerged. The first theme was the need for clear information and support for portfolio introduction, and anxieties about how this could be supported effectively. The second was that students had negative views about reflective learning and whether this could be taught and assessed, believing formal assessment could foster socially acceptable content. The third was that participants revealed little understanding of reflective learning and its potential benefits. Rather portfolios were seen as useful for concrete purposes (e.g., job applications) not intrinsic benefits. Undergraduate medical students without experience of portfolios are anxious about portfolio introduction. They require support in developing reflective learning skills. Care must be taken to ensure students do not see portfolios as merely yet another assessment hurdle.

    Family physicians often find themselves inadequately prepared to manage dementia. This article describes the curriculum for a resident training intervention in Primary Care Collaborative Memory Clinics (PCCMC), outlines its underlying educational principles, and examines its impact on residents' ability to provide dementia care. PCCMCs are family physician-led interprofessional clinic teams that provide evidence-informed comprehensive assessment and management of memory concerns. Within PCCMCs residents learn to apply a structured approach to assessment, diagnosis, and management; training consists of a tutorial covering various topics related to dementia followed by work-based learning within the clinic. Significantly more residents who trained in PCCMCs (sample = 98), as compared to those in usual training programs (sample = 35), reported positive changes in knowledge, ability, and confidence in ability to assess and manage memory problems. The PCCMC training intervention for family medicine residents provides a significant opportunity for residents to learn about best clinical practices and interprofessional care needed for optimal dementia care integrated within primary care practice.

    The question of optimal portfolio is addressed. The conventional Markowitz portfolio optimisation is discussed and the shortcomings due to non-Gaussian security returns are outlined. A method is proposed to minimise the likelihood of extreme non-Gaussian drawdowns of the portfolio value. The theory is called Leptokurtic, because it minimises the effects from “fat tails” of returns. The leptokurtic portfolio theory provides an optimal portfolio for investors, who define their risk-aversion as unwillingness to experience sharp drawdowns in asset prices. Two types of risks in asset returns are defined: a fluctuation risk, that has Gaussian distribution, and a drawdown risk, that deals with distribution tails. These risks are quantitatively measured by defining the “noise kernel” — an ellipsoidal cloud of points in the space of asset returns. The size of the ellipse is controlled with the threshold parameter: the larger the threshold parameter, the larger return are accepted for investors as normal fluctuations. The return vectors falling into the kernel are used for calculation of fluctuation risk. Analogously, the data points falling outside the kernel are used for the calculation of drawdown risks. As a result the portfolio optimisation problem becomes three-dimensional: in addition to the return, there are two types of risks involved. Optimal portfolio for drawdown-averse investors is the portfolio minimising variance outside the noise kernel. The theory has been tested with MSCI North America, Europe and Pacific total return stock indices.

    Full Text Available Especially when starting their career in the induction phase, young teachers need personal, profession-related and social support. Young teachers can get personal support with a mentoring system, profession-related support in seminars and social support with peer-learning. E-portfolios offer ways to accompany those learning processes and are a central tool for the documentation of individual student progress in the induction phase of teachers. In this article a concept of teaching e-portfolios for the induction phase is presented, showing a basic structure, essential conditions and possible risks. Additionally this article also includes practical thoughts to the use of e-portfolios in basic teacher education and further teacher training.

    The increased use of information technology supports a resident- centred educational approach that promotes autonomy, flexibility and time management and helps residents to assess their competence, promoting self-awareness. We established a web-based e-learning tool to introduce general surgery residents to bariatric surgery and evaluate them to determine the most appropriate implementation strategy for Internet-based interactive modules (iBIM) in surgical teaching. Usernames and passwords were assigned to general surgery residents at the University of Alberta. They were directed to the Obesity101 website and prompted to complete a multiple-choice precourse test. Afterwards, they were able to access the interactive modules. Residents could review the course material as often as they wanted before completing a multiple-choice postcourse test and exit survey. We used paired t tests to assess the difference between pre- and postcourse scores. Out of 34 residents who agreed to participate in the project, 12 completed the project (35.3%). For these 12 residents, the precourse mean score was 50 ± 17.3 and the postcourse mean score was 67 ± 14 (p = 0.020). Most residents who participated in this study recommended using the iBIMs as a study tool for bariatric surgery. Course evaluation scores suggest this novel approach was successful in transferring knowledge to surgical trainees. Further development of this tool and assessment of implementation strategies will determine how iBIM in bariatric surgery may be integrated into the curriculum.

    Community-based service learning (CBSL) provides an opportunity to teach internal medicine residents the social context of aging and clinical concepts. The objectives of the current study were to demonstrate the feasibility of a CBSL program targeting internal medicine residents and to assess its effect on medical residents and community participants. internal medicine residents participated in a CBSL experience for half a day during ambulatory blocks from 2011 to 2014. Residents attended a senior housing unit or center, delivered a presentation about a geriatric health topic, toured the facility, and received information about local older adult resources. Residents evaluated the experience. Postgraduate Year 3 internal medicine residents (n = 71) delivered 64 sessions. Residents felt that the experience increased their ability to communicate effectively with older adults (mean 3.91 ± 0.73 on a Likert scale with 5 = strongly agree), increased their knowledge of resources (4.09 ± 1.01), expanded their knowledge of a health topic pertinent to aging (3.48 ± 1.09), and contributed to their capacity to evaluate and care for older adults (3.84 ± 0.67). Free-text responses demonstrated that residents thought that this program would change their practice. Of 815 older adults surveyed from 36 discrete teaching sessions, 461 (56%) thought that the medical residents delivered health information clearly (4.55 ± 0.88) and that the health topics were relevant (4.26 ± 0.92). Free-text responses showed that the program helped them understand their health concerns. This CBSL program is a feasible and effective tool for teaching internal medicine residents and older adults. © 2017, Copyright the Authors Journal compilation © 2017, The American Geriatrics Society.

    The growth of e-learning in health professional education reflects expansion of personal use of online resources. Understanding the user perspective in a fast-changing digital world is essential to maintain the currency of our approach. Mixed methods were used to investigate a cohort of postgraduate, e-learning healthcare students' perspectives on their use of online resources for personal and/or professional roles, via questionnaire and student-constructed diagrams, capturing use of online resources (underpinned by White's model of "resident" and "visitor" online engagement). Semistructured interviews explored the use and value of resources afforded via the online environment. The 45 study participants described a range of prior experiences with online resources in personal and professional capacities, but overall students tended to use online "tools" ("visitor" mode) rather than highly collaborative networks ("resident" mode). In relation to e-learning, the dominant interview theme was valuing knowledge transfer from the tutor and using "visitor" behaviors to maximize knowledge acquisition. Peer-learning opportunities were less valued and barriers to collaborative "resident" modes were identified. These findings help to inform e-learning course design to promote engagement. The results enable recommendations for use of the "Visitor and Residents" model and for planning activities that learners might utilize effectively.

    The present study was done at the internal medicine service oft he Hospital lnfantil in the State of Sonora, Mexico. We tried to address the question of the use of conceptual schemes and mind maps and its impact on the teaching-learning-evaluation process among medical residents. Analyze the effects of conceptual schemes, and mind maps as a teaching and evaluation tool and compare them with multiple choice exams among Pediatric residents. Twenty two residents (RI, RII, RIII)on service rotation during six months were assessed initially, followed by a lecture on a medical subject. Conceptual schemes and mind maps were then introduced as a teaching-learning-evaluation instrument. Comprehension impact and comparison with a standard multiple choice evaluation was done. The statistical package (JMP version 5, SAS inst. 2004) was used. We noted that when we used conceptual schemes and mind mapping, learning improvement was noticeable among the three groups of residents (P evaluation tool when compared with multiple choice exams (P < 0.0005). Based on our experience we recommend the use of this educational technique for medical residents in training.

    Informal learners have many different backgrounds, experiences, and perspectives. How can informal educators effectively reach such diverse audiences, meeting people where they are with regard to climate change? The Polar Learning and Responding: PoLAR Climate Change Education Partnership, supported by NSF, employs surveys, resource development, and research to develop innovative, evidence-based approaches that engage lifelong learners. General-public surveys on climate change yield insights on the knowledge and perceptions that informal learners bring to the table. That helps guide the creation of new tools for effective communication. For example, many people are unsure what causes sea level to rise. The Polar Explorer: Sea Level app uses a data and question-based approach guiding people through interactive maps to learn about melting land ice. In addition, people also tend to believe that climate impacts will happen in the future. Polar Voices podcasts feature Arctic Indigenous communities sharing first-hand experiences with climate change. Prior knowledge can be harnessed to enhance learning. Arctic SMARTIC engages people in role-playing negotiations with others to create a marine management plan. Climate game jams provide collaborative, creative spaces where participants learn as they interact with others. In each case participants, with all their knowledge and experience, are brought into group problem-solving. Understanding whom people trust for climate-change information offers insights that help them become climate communicators. Even those who are concerned about climate often do not discuss it with family and friends (Maibach et al. 2016), yet our research shows that family and friends are second only to scientists as trusted sources of climate information (Hamilton 2016). Fun and novel educational tools such as the EcoChains card game and the EcoKoin social networking app serve as conversation starters.

    2018-01-01

    The authors developed a Transitions of Care (TOC) curriculum to teach and measure learner competence in performing TOC tasks for older adults. Internal medicine interns at an academic residency program received the curriculum, which consisted of experiential learning, self-study, and small group discussion. Interns completed retrospective pre/post surveys rating their confidence in performing five TOC tasks, qualitative open-ended survey questions, and a self-reflection essay. A subset of interns also completed follow-up assessments. For all five TOC tasks, the interns' confidence improved following completion of the TOC curriculum. Self-confidence persisted for up to 3 months later for some but not all tasks. According to the qualitative responses, the TOC curriculum provided interns with learning experiences and skills integral to performing safe care transitions. The TOC curriculum and a mixed-method assessment approach effectively teaches and measures learner competency in TOC across all six Accreditation Council for Graduate Medical Education competency domains.

    This paper discusses portfolio analysis as a method to evaluate utility supply decisions. Specifically a utility is assumed to increase the value of its portfolio of assets whenever it invests in a new supply technology. This increase in value occurs because the new asset either enhances the return or diversifies the risks of the firm's portfolio of assets. This evaluation method is applied to two supply innovations in the electric utility industry: jointly-owned generating plants and supply contracts with independent power producers (IPPs)

    Existing theories of self-directed learning (SDL) have emphasized the importance of process, personal, and contextual factors. Previous medical education research has largely focused on the process of SDL. We explored the experience with and perception of SDL among internal medicine residents to gain understanding of the personal and contextual factors of SDL in graduate medical education. Using a constructivist grounded theory approach, we conducted 7 focus group interviews with 46 internal medicine residents at an academic medical center. We processed the data by using open coding and writing analytic memos. Team members organized open codes to create axial codes, which were applied to all transcripts. Guided by a previous model of SDL, we developed a theoretical model that was revised through constant comparison with new data as they were collected, and we refined the theory until it had adequate explanatory power and was appropriately grounded in the experiences of residents. We developed a theoretical model of SDL to explain the process, personal, and contextual factors affecting SDL during residency training. The process of SDL began with a trigger that uncovered a knowledge gap. Residents progressed to formulating learning objectives, using resources, applying knowledge, and evaluating learning. Personal factors included motivations, individual characteristics, and the change in approach to SDL over time. Contextual factors included the need for external guidance, the influence of residency program structure and culture, and the presence of contextual barriers. We developed a theoretical model of SDL in medical education that can be used to promote and assess resident SDL through understanding the process, person, and context of SDL.

    2017-04-01

    Full Text Available In this study we are trying with the help of portfolio in teacher training and the diagnosis of the learning group concerning their skills in translation from German to Turkish, to show the documentation of the learning process. The portfolio provides a good overview about the performance of the students and it also prepares a basis for assessment. A growing self-awareness of students can be achieved through implementing the portfolio-method. The students should collect and reflect the most important materials and practices leading to key terms of the seminar. It is more than an assessment method it is a surrounding of learning. The work with portfolio has an influence on teaching, learning and assessing. As in detail, this is dependent on the aims and other characteristics of the models which take the portfolio work as a basis. The portfolio provides us a big advantage for the support of the cultural reflection. We can observe the process of the growth of knowledge step by step, because the measurement of the development in a determined period allows us either a written work or a Multiple Choice Test. In this sense we can look at the portfolio as an assessment instrument of a process.

    2011-12-01

    The Motivated Strategies for Learning Questionnaire (MSLQ) purports to measure motivation using the expectancy-value model. Although it is widely used in other fields, this instrument has received little study in health professions education. The purpose of this study was to evaluate the validity of MSLQ scores. We conducted a validity study evaluating the relationships of MSLQ scores to other variables and their internal structure (reliability and factor analysis). Participants included 210 internal medicine and family medicine residents participating in a web-based course on ambulatory medicine at an academic medical centre. Measurements included pre-course MSLQ scores, pre- and post-module motivation surveys, post-module knowledge test and post-module Instructional Materials Motivation Survey (IMMS) scores. Internal consistency was universally high for all MSLQ items together (Cronbach's α = 0.93) and for each domain (α ≥ 0.67). Total MSLQ scores showed statistically significant positive associations with post-test knowledge scores. For example, a 1-point rise in total MSLQ score was associated with a 4.4% increase in post-test scores (β = 4.4; p motivation and satisfaction. Scores on MSLQ domains demonstrated associations that generally aligned with our hypotheses. Self-efficacy and control of learning belief scores demonstrated the strongest domain-specific relationships with knowledge scores (β = 2.9 for both). Confirmatory factor analysis showed a borderline model fit. Follow-up exploratory factor analysis revealed the scores of five factors (self-efficacy, intrinsic interest, test anxiety, extrinsic goals, attribution) demonstrated psychometric and predictive properties similar to those of the original scales. Scores on the MSLQ are reliable and predict meaningful outcomes. However, the factor structure suggests a simplified model might better fit the empiric data. Future research might consider how assessing and responding to motivation could enhance

    Background Management of status epilepticus (SE) in the pediatric population is highly time-sensitive. Failure to follow a standard management algorithm may be due to ineffective provider education, and can lead to unfavorable outcomes. Objective To design a learning module using high-fidelity simulation technology to teach mastery achievement of a hospital algorithm for managing SE. Methods Thirty pediatrics interns were enrolled. Using the Angoff method, an expert panel developed the minimal passing score, which defined mastery. Scoring of simulated performance was done by 2 observers. Sessions were digitally recorded. After the pretest, participants were debriefed on the algorithm and required to repeat the simulation. If mastery (minimal passing score) was not achieved, debriefing and the simulation were repeated until mastery was met. Once mastery was met, participants graded their comfort level in managing SE. Results No participants achieved mastery at pretest. After debriefing and deliberate simulator training, all (n = 30) achieved mastery of the algorithm: 30% achieved mastery after 1 posttest, 63% after a second, and 6.7% after a third. The Krippendorff α was 0.94, indicating strong interrater agreement. Participants reported more self-efficacy in managing SE, a preference for simulation-based education for learning practice-based algorithms of critical conditions, and highly rated the educational intervention. Conclusions A simulation-based mastery learning program using deliberate practice dramatically improves pediatrics residents' execution of a SE management protocol. Participants enjoyed and benefited from simulation education. Future applications include improving adherence to other hospital protocols. PMID:26221431

    Starn, J. J.; Belitz, K.; Carlson, C.

    2017-12-01

    Groundwater residence-time distributions (RTDs) are critical for assessing susceptibility of water resources to contamination. This novel approach for estimating regional RTDs was to first simulate groundwater flow using existing regional digital data sets in 13 intermediate size watersheds (each an average of 7,000 square kilometers) that are representative of a wide range of glacial systems. RTDs were simulated with particle tracking. We refer to these models as "general models" because they are based on regional, as opposed to site-specific, digital data. Parametric RTDs were created from particle RTDs by fitting 1- and 2-component Weibull, gamma, and inverse Gaussian distributions, thus reducing a large number of particle travel times to 3 to 7 parameters (shape, location, and scale for each component plus a mixing fraction) for each modeled area. The scale parameter of these distributions is related to the mean exponential age; the shape parameter controls departure from the ideal exponential distribution and is partly a function of interaction with bedrock and with drainage density. Given the flexible shape and mathematical similarity of these distributions, any of them are potentially a good fit to particle RTDs. The 1-component gamma distribution provided a good fit to basin-wide particle RTDs. RTDs at monitoring wells and streams often have more complicated shapes than basin-wide RTDs, caused in part by heterogeneity in the model, and generally require 2-component distributions. A machine learning model was trained on the RTD parameters using features derived from regionally available watershed characteristics such as recharge rate, material thickness, and stream density. RTDs appeared to vary systematically across the landscape in relation to watershed features. This relation was used to produce maps of useful metrics with respect to risk-based thresholds, such as the time to first exceedance, time to maximum concentration, time above the threshold

    The neutron criticality accident at the JCO, a private company for nuclear fuel processing facilities in Tokai has drastically changed minds and attitudes of residents toward environmental radioactivity. The accident happened on September 30, 1999. Before the accident the residents of the Rokkasho Site were not anxious about environmental radioactivity, because they thought the facilities were safe enough concerning containment policy of the radioactivity inside the facilities. Residents, however, had not been taught on a neutron. It is an unfamiliar radiation for them. So, they promptly learnt on neutrons, and some of them began the fixed point measurement of neutrons at the nearest site of the Spent Fuel Recycling Facilities of Rokkasho by the help of Prof. Kazuhisa. Komura, Kanazawa University. Members of the Reading Cicle, Rokkasho Culture Society, mainly women, learnt measurements of environmental radioactivity using simplified counters for alpha-, beta-, and gamma-ray from natural radioactive elements and prepared various kinds of environmental samples. After learning of environmental radioactivity, they began educational activities on the environmental radioactivity for boys and girls in the region. Monitoring of environmental radioactivity is performed by different institutions and with their purposes. Here is reported learning of environmental radioactivity by the residents and education of environmental radioactivity toward the young. Even with the simplest counters, we think that the monitoring of environmental radioactivity by the residents themselves is the royal road to the safety of the regional society. (author)

    Residents' attitudes toward error disclosure have improved over time. It is unclear whether this has been accompanied by improvements in disclosure skills. To measure the disclosure skills of internal medicine (IM), paediatrics, and orthopaedic surgery residents, and to explore resident perceptions of formal versus informal training in preparing them for disclosure in real-world practice. We assessed residents' error disclosure skills using a structured role play with a standardized patient in 2012-2013. We compared disclosure skills across programs using analysis of variance. We conducted a multiple linear regression, including data from a historical cohort of IM residents from 2005, to investigate the influence of predictor variables on performance: training program, cohort year, and prior disclosure training and experience. We conducted a qualitative descriptive analysis of data from semistructured interviews with residents to explore resident perceptions of formal versus informal disclosure training. In a comparison of disclosure skills for 49 residents, there was no difference in overall performance across specialties (4.1 to 4.4 of 5, P  = .19). In regression analysis, only the current cohort was significantly associated with skill: current residents performed better than a historical cohort of 42 IM residents ( P  formal (workshops, morbidity and mortality rounds) and informal (role modeling, debriefing) activities in preparation for disclosure in real-world practice. Residents across specialties have similar skills in disclosure of errors. Residents identified role modeling and a strong local patient safety culture as key facilitators for disclosure.

    Full Text Available Despite the increasing popularity of primary care sports medicine fellowships, as evidenced by the more than two-fold increase in family medicine sports medicine fellowships from a total of 31 accredited programs during the 1998/1999 academic year (ACGME, 1998 to 63 during the 2003/2004 academic year (ACGME, 2006, there are few empirical studies to support the efficacy of such programs. To the best of our knowledge, no studies have been conducted to assess the impact of primary care sports medicine fellowships on family medicine residents' learning of non-musculoskeletal sports medicine topics. Rigorous evaluations of the outcomes of such programs are helpful to document the value of such programs to both the lay public and interested medical residents. In order to evaluate such programs, it is helpful to apply the same objective standards to residents trained across multiple programs. Hence, we would like to know if there is a learning effect with respect to non-musculoskeletal sports medicine topics identified on yearly administered American Board of Family Medicine (ABFM in-training exams (ITE to family medicine residents in family medicine residency programs in the United States with and without primary care sports medicine fellowship programs. Review and approval for the research proposal was granted by the ABFM, who also allowed access to the required data. Permission to study and report only non-musculoskeletal sports medicine topics excluding musculoskeletal topics was granted at the time due to other ongoing projects at the ABFM involving musculoskeletal topics. ABFM allowed us access to examinations from 1998 to 2003. We were given copies of each exam and records of responses to each item (correct or incorrect by each examinee (examinees were anonymous for each year.For each year, each examinee was classified by the ABFM as either (a belonging to a program that contained a sports medicine fellowship, or (b not belonging to a program

    Riaño, David; Real, Francis; Alonso, Jose Ramon

    2018-05-01

    Correct clinical management of circulatory shock in emergency departments (ER) and intensive care units (ICU) is critical. In this context, the transmission of professional skills by means of the practical supervision of real cases at the point of care entails important issues that can be widely overcome with the use of computer knowledge-based e-learning tools. Shock-Instructor is a web-based e-learning tool implementing the already tested training program model (TPM) that uses a knowledge base about the evidence found in the clinical practice guidelines about seven types of shock. This tool is expected to reduce the learning times and to improve the skills of hospital residents with regard to both the correct application of the guidelines and patient recovery, suppressing the risks of direct interventions. Shock-Instructor has been used to train residents in the Emergency Department of the Hospital Clínic de Barcelona (Spain) in order to reduce the learning cycle without affecting quality. A case-base with the description of 51 cases with shock and a knowledge-base with 137 clinical rules about the treatment of shock were incorporated to the Shock-Instructor system. A group of 33 residents was involved in a randomized controlled trial to check whether the use of Shock-Instructor can significantly improve the skills of clinicians after one week of problem-based training. No significant differences were found in the skill levels of the intervention (IG) and control (CG) groups prior to learning. However, we observed an improvement of the IG clinicians capacity to stabilize patients with shock in better clinical conditions (5% improvement, p = 0.004), and to reduce the risk of death in 19.52% (p = 0.004), after training. First-year residents in IG enhanced 14.3% their sensitivity in the correct application of guidelines (p = 0.01), and 14.9% the mean survival rate of their patients (p = 0.01), after being trained with Shock-Instructor for a week

    Full Text Available Background: By using web-based tools in medical education, there are opportunities to innovatively teach important principles from the general competencies of graduate medical education. Objectives: Postulating that faculty transparency in learning from uncertainties in clinical work could help residents to incorporate the principles of practice-based learning and improvement (PBLI in their professional development, faculty in this community-based residency program modeled the steps of PBLI on a weekly basis through the use of a web log. Method: The program confidentially surveyed residents before and after this project about actions consistent with PBLI and knowledge acquired through reading the web log. Results: The frequency that residents encountered clinical situations where they felt uncertain declined over the course of the 24 weeks of the project from a mean frequency of uncertainty of 36% to 28% (Wilcoxon signed rank test, p=0.008; however, the frequency with which residents sought answers when faced with uncertainty did not change (Wilcoxon signed rank test, p=0.39, remaining high at approximately 80%. Residents answered a mean of 52% of knowledge questions correct when tested prior to faculty posts to the blog, rising to a mean of 65% of questions correct when tested at the end of the project (paired t-test, p=0.001. Conclusions: Faculty role modeling of PBLI behaviors and posting clinical questions and answers to a web log led to modest improvements in medical knowledge but did not alter behavior that was already taking place frequently among residents.

    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

    To examine the role of classroom-based learning in graduate medical education through the lens of academic half days (AHDs) by exploring residents' perceptions of AHDs' purpose and relevance and the effectiveness of teaching and learning in AHDs. The authors invited a total of 186 residents in three programs (internal medicine, orthopedic surgery, and hematology) at the University of British Columbia Faculty of Medicine to participate in semistructured focus groups from October 2010 to February 2011. Verbatim transcripts of the interviews underwent inductive analysis. Twenty-seven residents across the three programs volunteered to participate. Two major findings emerged. Purpose and relevance of AHDs: Residents believed that AHDs are primarily for knowledge acquisition and should complement clinical learning. Classroom learning facilitated consolidation of clinical experiences with expert clinical reasoning. Social aspects of AHDs were highly valued as an important secondary purpose. Perceived effectiveness of teaching and learning: Case-based teaching engaged residents in critical thinking; active learning was valued. Knowledge retention was considered suboptimal. Perspectives on the concept of AHDs as "protected time" varied in the three programs. Findings suggest that (1) engagement in classroom learning occurs through participation in clinically oriented discussions that highlight expert reasoning processes; (2) formal classroom teaching, which focuses on knowledge acquisition, can enhance informal learning occurring during clinical activity; and (3) social aspects of AHDs, including their role in creating communities of practice in residency programs and in professional identity formation, are an important, underappreciated asset for residency programs.

    Reflecting on workplace-based experiences is necessary for professional development. However, residents need support to raise their awareness of valuable moments for learning and to thoughtfully analyze those learning moments afterwards. From October to December 2012, the authors held a multidisciplinary six-week postgraduate training module focused on general competencies. Residents were randomly assigned to one of four conditions with varying degrees of reflection support; they were offered (1) a smartphone app, (2) coaching group sessions, (3) a combination of both, or (4) neither type of support. The app allowed participants to capture in real time learning moments as a text note, audio recording, picture, or video. Coaching sessions held every two weeks aimed to deepen participants' reflection on captured learning moments. Questionnaire responses and reflection data were compared between conditions to assess the effects of the app and coaching sessions on intensity and frequency of reflection. Sixty-four residents participated. App users reflected more often, captured more learning moments, and reported greater learning progress than nonapp users. Participants who attended coaching sessions were more alert to learning moments and pursued more follow-up learning activities to improve on the general competencies. Those who received both types of support were most alert to these learning moments. A simple mobile app for capturing learning moments shows promise as a tool to support workplace-based learning, especially when combined with coaching sessions. Future research should evaluate these tools on a broader scale and in conjunction with residents' and students' personal digital portfolios.

    To design and validate an objective practical assessment tool for diagnostic shoulder arthroscopy that would provide residents with a method to evaluate their progression in this field of surgery and to identify specific learning needs. We designed and evaluated the shoulder Objective Practical Assessment Tool (OPAT). The shoulder OPAT was designed by us, and scoring domains were created using a Delphi process. The shoulder OPAT was trialed by members of the British Elbow & Shoulder Society Education Committee for internal consistency and ease of use before being offered to other trainers and residents. Inter-rater reliability and intrarater reliability were calculated. One hundred forty orthopaedic residents, of varying seniority, within 5 training regions in the United Kingdom, were questioned regarding the tool. A pilot study of 6 residents was undertaken. Internal consistency was 0.77 (standardized Cronbach α). Inter-rater reliability was 0.60, and intrarater reliability was 0.82. The Spearman correlation coefficient (r) between the global summary score for the shoulder OPAT and the current assessment tool used in postgraduate training for orthopaedic residents undertaking diagnostic shoulder arthroscopy equaled 0.74. Of the residents, 82% agreed or strongly agreed when asked if the shoulder OPAT would be a useful tool in monitoring progression and 72% agreed or strongly agreed with the introduction of the shoulder OPAT within the orthopaedic domain. This study shows that the shoulder OPAT fulfills several aspects of reliability and validity when tested. Despite the inter-rater reliability being 0.60, we believe that the shoulder OPAT has the potential to play a role alongside the current assessment tool in the training of orthopaedic residents. The shoulder OPAT can be used to assess residents during shoulder arthroscopy and has the potential for use in medical education, as well as arthroscopic skills training in the operating theater.

    Full Text Available Abstract Background How medical residents’ experiences with care for dying patients affect their emotional well-being, their learning outcomes, and the formation of their professional identities is not fully understood. We examine residents’ emotional states and learning occurring during the provision of care to dying patients and specifically discuss the impact of providing end-of-life (EOL care on professional identity formation. Methods Semi-structured interviews were conducted with 13 residents who had graduated in the last 3 to 5 years. Thematic theoretical analysis was applied, and key themes were developed based on Kolb’s experiential learning cycle. Results Eight key themes emerged from the analysis. The residents experienced dilemmas in confronting the reality of medical uncertainty as well as a disruption of emotional state and self-efficacy. Although the residents felt a sense of helplessness and guilt, they were able to reflect on strategies for handling medical care that focused on patients and that required a truly sincere attitude. They also contemplated the importance of palliative care and communication with patients, patients’ family members and medical staff. Building on these experiences, the residents rebuilt a sense of awareness that allowed them to directly engage with the type of medical care that they are likely to be called upon to perform in the future as the population continues to age. Conclusions This study revealed Japanese residents’ perceptions, emotions and learning processes in caring for dying patients by applying Kolb’s experiential learning theory. The findings of this study may illuminate valuable pieces of knowledge for future education in EOL care.

    This study aimed to assess the efficacy of a route-learning training in a group of older adults living in a residential care home. We verified the presence of training-specific effects in tasks similar to those trained - route-learning tasks - as well as transfer effects on related cognitive processes - visuo-spatial short-term memory (VSSTM; Corsi Blocks Test (CBT), forward version), visuo-spatial working memory (VSWM; CBT, backward version; Pathway Span Tasks; Jigsaw Puzzle Test) - and in self-report measures. The maintenance of training benefits was examined after 3 months. Thirty 70-90-year-old residential care home residents were randomly assigned to the route-learning training group or to an active control group (involved in non-visuo-spatial activities). The trained group performed better than the control group in the route-learning tasks, retaining this benefit 3 months later. Immediate transfer effects were also seen in visuo-spatial span tasks (i.e., CBT forward and backward version and Pathway Span Task); these benefits had been substantially maintained at the 3-month follow-up. These findings suggest that a training on route learning is a promising approach to sustain older adults' environmental learning and some related abilities (e.g., VSSTM and VSWM), even in residential care home residents.

    2003-12-01

    Full Text Available We use a mean-variance model to analyze the problem of decentralized portfolio management. We find the solution for the optimal portfolio allocation for a head trader operating in n different markets, which is called the optimal centralized portfolio. However, as there are many traders specialized in different markets, the solution to the problem of optimal decentralized allocation should be different from the centralized case. In this paper we derive conditions for the solutions to be equivalent. We use multivariate normal returns and a negative exponential function to solve the problem analytically. We generate the equivalence of solutions by assuming that different traders face different interest rates for borrowing and lending. This interest rate is dependent on the ratio of the degrees of risk aversion of the trader and the head trader, on the excess return, and on the correlation between asset returns.

    Simulation-based learning is emerging as an alternative educational tool in this era of a relative shortfall of teaching anesthesiologists. The objective of the study is to assess whether screen-based (interactive computer simulated) case scenarios are more effective than problem-based learning discussions (PBLDs) in improving test scores 4 and 8 weeks after these interventions in anesthesia residents during their first neuroanesthesia rotation. Prospective, nonblinded quasi-crossover study. Cleveland Clinic. Anesthesiology residents. Two case scenarios were delivered from the Anesoft software as screen-based sessions, and parallel scripts were developed for 2 PBLDs. Each resident underwent both types of training sessions, starting with the PBLD session, and the 2 cases were alternated each month (ie, in 1 month, the screen-based intervention used case 1 and the PBLD used case 2, and vice versa for the next month). Test scores before the rotation (baseline), immediately after the rotation (4 weeks after the start of the rotation), and 8 weeks after the start of rotation were collected on each topic from each resident. The effect of training method on improvement in test scores was assessed using a linear mixed-effects model. Compared to the departmental standard of PBLD, the simulation method did not improve either the 4- or 8-week mean test scores (P = .41 and P = .40 for training method effect on 4- and 8-week scores, respectively). Resident satisfaction with the simulation module on a 5-point Likert scale showed subjective evidence of a positive impact on resident education. Screen-based simulators were not more effective than PBLD for education during the neuroanesthesia rotation in anesthesia residency. Copyright © 2016 Elsevier Inc. All rights reserved.

    It is vital for physicians and surgeons to communicate successfully with older adults, who will constitute one-fifth of the US population by 2030. Older adults often perceive themselves as stigmatized and powerless in healthcare settings. Effective communication leads to better patient compliance and satisfaction, which is now a component of Medicare hospital reimbursement and physician and surgeon compensation from hospitals and networks. To increase orthopaedic surgery resident understanding of the unique needs of older adults in order to maintain effective and sensitive communication with this vulnerable population. A two-part training program (ongoing for 8 years) comprised of: 1) small-group interactive didactic sessions on aging issues; and 2) workshop demonstrations given by the residents to a group of older adults, followed by a Question & Answer session. Residents were assessed using a 22-item pre-post questionnaire covering medical knowledge of aging, attitudes toward older adults, and personal anxiety about aging. Older adult participants were surveyed for perceptions of residents' sensitivity toward them. Hospital for Special Surgery in New York City, a specialized urban academic center, with a 5-year Orthopedic Surgery Residency program. 70 PGY3 residents, for whom the program is a requirement, and 711 older adult participants recruited from a community convenience sample. Older adult participants: Of 711 participants, 672 (95%) responded; 96% strongly agreed/agreed that the residents had demonstrated sensitivity toward them. Residents: Of 70 residents, 35 (50%) were assessed. Mean knowledge scores increased significantly (p ≤ 0.001); five of nine attitude items (p ≤ 0.05) and one of four anxiety items improved significantly (p ≤ 0.001). Significant change was seen in residents' attitudes and anxiety levels toward older adults, attributes that are usually deep seated and hard to change.

    We present an approach to multi-stage international portfolio optimization based on the imposition of a linear structure on the recourse decisions. Multiperiod decision problems are traditionally formulated as stochastic programs. Scenario tree based solutions however can become intractable as the number of stages increases. By restricting the space of decision policies to linear rules, we obtain a conservative tractable approximation to the original problem. Local asset prices and foreign exchange rates are modelled separately, which allows for a direct measure of their impact on the final portfolio value.

    2009-06-01

    The need for an alternative means of delivery of a didactic curriculum to pediatric dental residents is described. It is our hope with this project to encourage a much-needed didactic curriculum for programs lacking faculty and to endorse other programs in which academicians exist but cannot cover all the material with which a resident needs to become familiar in the two years of postgraduate residency training. A decrease in faculty number due to retirement, debt burden, or marginal recruitment techniques along with an increase in positions in pediatric dentistry residency programs poses a unique educational dilemma. Using a mixed-method research methodology, we sent a twelve-question survey to 105 pediatric dentistry residency program directors and department chairs, followed by eight telephone interviews. Results from a 55 percent return rate show that the debt burden of most pediatric dental residents is well over $100,000 and that this affects a resident's decision to enter academia, as does the relative lack of positive recruitment techniques and poor faculty remuneration. The survey results affirm the need for improvement in the didactic curriculum of pediatric dentistry residents and show that program directors and department chairs also feel that an alternative delivery method using DVD or online/web-based programs would be welcomed. Despite their extremely heavy workloads, educators are willing to contribute by providing lectures or reading lists in their area of expertise.

  12. Developing resident learning profiles: Do scientific evidence epistemology beliefs, EBM self-efficacy beliefs and EBM skills matter?

    Science.gov (United States)

    Robert, Nancy J.

    This study investigated resident scientific evidence epistemology beliefs, evidence based medicine (EBM) self-efficacy beliefs, and EBM skills. A convenience sample of fifty-one residents located in six U.S. based residency programs completed an online instrument. Hofer's epistemology survey questionnaire was modified to test responses based on four types of scientific evidence encountered in medical practice (Clinical Trial Phase 1, Clinical Trial Phase 3, Meta-analysis and Qualitative). It was hypothesized that epistemology beliefs would differ based on the type of scientific evidence considered. A principal components analysis produced a two factor solution that was significant across type of scientific evidence suggesting that when evaluating epistemology beliefs context does matter. Factor 1 is related to the certainty of research methods and the certainty of medical conclusions and factor 2 denotes medical justification. For each type of scientific evidence, both factors differed on questions comprising the factor structure with significant differences found for the factor 1 and 2 questions. A justification belief case problem using checklist format was triangulated with the survey results, and as predicted the survey and checklist justification z scores indicated no significant differences, and two new justification themes emerged. Modified versions of Finney and Schraw's statistical self-efficacy and skill instruments produced expected significant EBM score correlations with unexpected results indicating that the number of EBM and statistics courses are not significant for EBM self-efficacy and skill scores. The study results were applied to the construction of a learning profile that provided residents belief and skill feedback specific to individual learning needs. The learning profile design incorporated core values related to 'Believer' populations that focus on art, harmony, tact and diplomacy. Future research recommendations include testing context

    2009-07-28

    We consider the problem of portfolio selection within the classical Markowitz mean-variance framework, reformulated as a constrained least-squares regression problem. We propose to add to the objective function a penalty proportional to the sum of the absolute values of the portfolio weights. This penalty regularizes (stabilizes) the optimization problem, encourages sparse portfolios (i.e., portfolios with only few active positions), and allows accounting for transaction costs. Our approach recovers as special cases the no-short-positions portfolios, but does allow for short positions in limited number. We implement this methodology on two benchmark data sets constructed by Fama and French. Using only a modest amount of training data, we construct portfolios whose out-of-sample performance, as measured by Sharpe ratio, is consistently and significantly better than that of the naïve evenly weighted portfolio.

    Full Text Available The article notes that the task of the investor's risk management is to, on the one hand, as much as possible to strive to achieve the criterion of risk level, and on the other hand, in any case not exceed it. Since the domestic theory of risk management is under development, the problem of the optimal ratio of "risk-income" becomes now of particular relevance. This article discusses the different distribution areas of the private investor in order to obtain the maximum profit. The analysis showed us the overall economic and political system of the country, as well as the legislative provision of guarantees to the investor. To obtain sufficient income and reduce losses it is important to maintain the optimum value found between the amount of the investor's risk and capital transactions. Model of optimal placement of funds led to the conclusion about inexpediency strong increase in the diversification of the investment portfolio (more than 10 different types of assets in the portfolio, since it increases the complexity of its practical form, while the portfolio characteristics are improved significantly. It is concluded that it is impossible to increase revenue without increasing the risk or reduce risk without reducing income. The analysis shows that there is no single best asset portfolio. It is impossible to increase revenue without increasing the risk or reduce risk without reducing income. Possible combination of the "riskincome" will depend on the objective function. Most diversified and bringing the best return per unit of risk, is a portfolio that contains the most risky assets.

    Portfolios are increasingly used in undergraduate and postgraduate medical education. Four medical schools have collaborated with an established NHS electronic portfolio provider to develop and implement an authentic professional electronic portfolio for undergraduate students. We hypothesized that using an authentic portfolio would have significant advantages for students, particularly in familiarizing them with the tool many will continue to use for years after graduation. This paper describes the early evaluation of this undergraduate portfolio at two participating medical schools. To gather data, a questionnaire survey with extensive free text comments was used at School 1, and three focus groups were held at School 2. This paper reports thematic analysis of students' opinions expressed in the free text comments and focus groups. Five main themes, common across both schools were identified. These concerned the purpose, use and acceptability of the portfolio, advantages of and barriers to the use of the portfolio, and the impacts on both learning and professional identity. An authentic portfolio mitigated some of the negative aspects of using a portfolio, and had a positive effect on students' perception of themselves as becoming past of the profession. However, significant barriers to portfolio use remained, including a lack of understanding of the purpose of a portfolio and a perceived damaging effect on feedback.

This study sought to evaluate the viability of a web-based curriculum in teaching electrocardiogram (EKG) reading skills to psychiatry residents. Interest in receiving educational materials in this format was also assessed. A web-based curriculum of 41 slides, including eight pre-test and eight post-test questions with emphasis on cardiac complications of psychotropic medications, was made available to all psychiatry residents via email. Out of 57 residents, 30 initiated and 22 completed the module. Mean improvement from pre-test to post-test was 25 %, and all 22 completing participants indicated interest in future web-based instruction. This pilot study suggests that web-based instruction is feasible and under-utilized as a means of teaching psychiatry residents. Potential uses of web-based instruction, such as tracking learning outcomes or patient care longitudinally, are also discussed.

    Adolescent Medicine (AM) educators in pediatric residency programs are seeking new ways to engage learners in adolescent health. This mixed-methods study presents a novel self-reflection tool and addresses whether self-reflection enhanced residents' perception of the value of an adolescent rotation, in particular, its relevance to their future practice. The self-reflection tool included 17 Likert scale items on residents' comfort with the essential tasks of adolescent care and open-ended questions that promoted self-reflection and goal setting. Semi-structured, postrotation interviews encouraged residents to discuss their experiences. Likert scale data were analyzed using descriptive statistics, and interview notes and written comments on the self-reflection tool were combined for qualitative data analysis. Residents' pre-to post-self-evaluations showed statistically significant increases in comfort with most of the adolescent health care tasks. Four major themes emerged from our qualitative analysis: (1) the value of observing skilled attendings as role models; (2) the comfort gained through broad and frequent adolescent care experiences; (3) the career relevance of AM; and (4) the ability to set personally meaningful goals for the rotation. Residents used the self-reflection tool to mindfully set goals and found their AM education valuable and relevant to their future careers. Our tool helped make explicit to residents the norms, values, and beliefs of the hidden curriculum applied to the care of adolescents and helped them to improve the self-assessed quality of their rapport and communications with adolescents. We conclude that a structured self-reflection exercise can enhance residents' experiences on an AM rotation. Copyright © 2016 Society for Adolescent Health and Medicine. Published by Elsevier Inc.

    Podcasts are increasingly being used in medical education. In this study, we conducted a survey of Canadian anesthesia residents to better delineate the content needs, format preferences, and usage patterns among anesthesia residents. 10/16 Canadian anesthesia program directors, representing 443/659 Canadian anesthesia residents, allowed their residents to be included in the study. 169/659 (24%) residents responded to our survey. A 17-item survey tool developed by the investigators was distributed by email eliciting information on patterns of podcast use, preferred content, preferred format, and podcast adjuncts perceived to increase knowledge retention. 60% (91/151) had used medical podcasts with 67% of these users spending up to 1 hour per week on podcasts. 72.3% of respondents selected 'ability to review materials whenever I want' was selected by the majority of respondents (72%) as the reason they found podcasts to be valuable. No clear preference was shown for audio, video, or slidecast podcasts. Physiology (88%) and pharmacology (87%) were the most requested basic science topics while regional anesthesia (84%), intensive care (79%) and crisis resource management (86%) were the most requested for procedural, clinical and professional topics respectively. Respondents stated they would most likely view podcasts that contained procedural skills, journal article summaries and case presentations and that were between 5-15 minutes in duration A significantly greater proportion of senior residents (81%) requested podcasts on 'pediatric anesthesia' compared to junior residents 57% (P = 0.007). The majority of respondents are using podcasts. Anesthesia residents have preferred podcast content, types, length and format that educators should be cognizant of when developing and providing podcasts.

    Full Text Available Electronic portfolio (e-Portfolio is known as an electronic learning record which collects the learning evidences, reflections and accomplishments. In fact, it tells the story of learning achievements. It is an important tool for students, lecturers, administrators and faculties to monitor the learning outcomes. Similarly to other technologies, e-Portfolio is also considered successful, if it is used by students continuously. Previous researches showed the importance of intrinsic and extrinsic motivations in using any technologies. However, lack of motivation has been a major concern for developing any successful online learning environments. The aim of this paper is to explain the e-Portfolio motivational factors from students’ perspective. Interviews are conducted with students from one university in Malaysia in order to get better understanding of the phenomena. The target interviewees are bachelor students chosen from different faculties. Based on the qualitative content analysis of the interviews, the motivational factors affecting the continuous use of e-portfolio are coded in eight themes and then they categorized in four main groups of individual, system, social and environmental characteristics. Finally they are classified into intrinsic or extrinsic motivations.

    This paper reports that the need for managing the acreage portfolio in the UK North Sea arises from fragmentation of holdings and complex field partnerships. The main concepts are building up the heartlands and balancing cashflow forecasts. This has generated a number of friendly win-win deals, motivated by differences in perception of values. The business process includes identifying, evaluating and negotiating deals. The Petroleum Economist plays a central role throughout this process, seeking value gaps and supporting negotiations. Variations in reserves estimates present a major source of value gaps between buyer and seller. Economists need to work closely with engineers and geologists. Portfolio management is an exciting and challenging task which broadens the traditional role of the Petroleum Economist

  4. On portfolio risk diversification

    Takada, Hellinton H.; Stern, Julio M.

    2017-06-01

    The first portfolio risk diversification strategy was put into practice by the All Weather fund in 1996. The idea of risk diversification is related to the risk contribution of each available asset class or investment factor to the total portfolio risk. The maximum diversification or the risk parity allocation is achieved when the set of risk contributions is given by a uniform distribution. Meucci (2009) introduced the maximization of the Rényi entropy as part of a leverage constrained optimization problem to achieve such diversified risk contributions when dealing with uncorrelated investment factors. A generalization of the risk parity is the risk budgeting when there is a prior for the distribution of the risk contributions. Our contribution is the generalization of the existent optimization frameworks to be able to solve the risk budgeting problem. In addition, our framework does not possess any leverage constraint.

    Clients, patients, families, and communities must be conceived as partners in care delivery, not just as recipients (D'Amour, D. & Oandasan, I. (2005). Journal of Interprofessional Care, 19(Suppl.), 8-20). Health-care students need an opportunity to understand community member self-determination, partnership, and empowerment (Scheyett, A., & Diehl, M. ( 2004 ). Social Work Education, 23(4), 435-450), within the frame of interprofessional education (IPE) where community members are involved as teachers and learners. The aim of this grounded theory research was to determine the conditions that support health-care students to learn with, from, and about community members. This study took place in a shelter for the homeless where nursing and social work students learned interprofessionally along with residents and clients of the shelter. Data were gathered through 7 months of participant observation, interviews, and focus groups. The interprofessional co-learning theory that emerged introduces the three phases of entering, engaging, and emerging, which co-learners experienced at different levels of intensity. This article outlines the conditions that support each of these phases of the co-learning process. This interprofessional co-learning theory provides a basis for further development and evaluation of IPE programs that strive to actively include community members as teachers and learners, experts, and novices together with service providers, students, and faculty members.

    Full Text Available Denne artikel sammenligner lærings e-portfolier med profiler i social software (Facebook, MySpace, LinkedIn. Ligheder mellem de to består i, at de begge er fora for selvfremstilling. Forskellen mellem dem består i, at selvet bliver fremstillet med to forskellige formål. Selvfremstillingen i social software sker for at være én i gruppen (af venner eller af professionelle. Det mulige selv-udtryk er defineret af den type input, som platformen vælger som vigtigt. I en e-portfolio er formålet at ”vise og fortælle” om kompetencer og udvikling – og dette sker gennem fri tekst og visuel formgivning. Dette er vanskeligt i det sociale software, vi kender i dag. I en e-portfolio demonstrerer måden du repræsenterer dig selv på din kommunikative kompetence. Bør uddannelsesinstitutioner så ignorere eller endog forbyde brugen af profiler? Artiklen foreslår en måde, hvorpå de ville kunne drage fordel af en dobbelt strategi. For det første sætter institutionen ved at igangsætte et e-portfolio-program eleverne/de studerende i stand til at udvikle og kende deres kompetencer som lærende. En af e-portfolio-litteraturens (Qvortrup, Lund, Ellmin hovedkonklusioner er, at refleksion over læring sætter den lærende i stand til at forstå og erkende egne kompetencer. For det andet kan brugen af social software influere den studerendes evne til at danne relationer – og fokusere kompetencen til at skabe og vedligeholde professionelle relationer. Denne strategi er en fordel, fordi den adresserer et problem, som institutioner ofte møder, når de igangsætter et e-portfolio-program. De studerende føler ikke nogen ”indre nødvendighed” i forhold til at udfylde dem. De ser ikke e-portfolien som en måde at overtale deres læsere – måske fordi de gennem e-portfolien taler til et ukendt publikum.

    2017-08-01

    Classroom-based learning such as academic half day has undervalued social aspects. We sought to explore its role in the professional identity development of family medicine residents. In this case study, residents and faculty from four training sites in the University of British Columbia Department of Family Practice were interviewed. The "experiences, trajectories, and reifications (ETR) framework" was used as a sensitizing tool for modified inductive (thematic) analysis of the transcripts. Classroom-based learning provided a different context for residents' interpretation of their clinical experiences, characterized as a "home base" for rotating urban residents, and a connection to a larger academic community for residents in rural training sites. Both these aspects were important in creating a positive trajectory of professional identity formation. Teaching directed at the learning needs of family physicians, and participation of family practice faculty as teachers and role models was a precipitation of a curriculum "centered in family medicine." Interactions between family medicine residents and faculty in the classroom facilitated the necessary engagements to reify a shared understanding of the discipline of family practice. Classroom-based learning has substantial impact on professional identity formation at an individual and collective level.

    To investigate residents' self-reported satisfaction level with their proficiency in extracapsular cataract extraction (ECCE) surgery and the initial barriers to learning the procedure. This is a single-centre prospective descriptive case series involving eight first-year ophthalmology residents in Singapore National Eye Center. We recorded the demographics, frequency of review by the residents of their own surgical videos and their satisfaction level with their proficiency at each of the ECCE steps using a 5-point Likert scale. All ECCE surgical videos between October 2013 and May 2014 were collected and analysed for the overall time taken for the surgery and the time taken to perform the individual steps of the procedure. The mean age of the residents was 27.6 ± 1.5 years and 62.5% (5/8) were women. More than half (62.5%, 5/8) reviewed their own surgical videos while 37.5% (3/8) discussed the surgical videos with their peers or supervisors. Of the ECCE steps, the residents were most dissatisfied with their proficiency in performing irrigation and aspiration (87.5%, 7/8), followed by suturing (62.5%, 5/8), intraocular lens insertion (62.5%, 5/8) and tin can capsulotomy (62.5%, 5/8). The average time taken for each ECCE case was 55.0 ± 12.2 min and, of all the steps, most time was spent on suturing (20.5 ± 6.8 min), followed by irrigation and aspiration (5.5 ± 3.6 min) and tin can capsulotomy (3.3 ± 1.8 min). The first-year ophthalmology residents were most dissatisfied with their proficiency in irrigation/aspiration, suturing and tin can capsulotomy. More training needs to be directed to these areas during teaching sessions in the operating room, wet laboratory or cataract simulation training sessions.

    Nursing homes (NHs) using the Preferences for Everyday Living Inventory (PELI-NH) to assess important preferences and provide person-centered care find the number of items (72) to be a barrier to using the assessment. Using a sample of n = 255 NH resident responses to the PELI-NH, we used the 16 preference items from the MDS 3.0 Section F to develop a machine learning recommender system to identify additional PELI-NH items that may be important to specific residents. Much like the Netflix recommender system, our system is based on the concept of collaborative filtering whereby insights and predictions (e.g., filters) are created using the interests and preferences of many users. The algorithm identifies multiple sets of "you might also like" patterns called association rules, based upon responses to the 16 MDS preferences that recommends an additional set of preferences with a high likelihood of being important to a specific resident. In the evaluation of the combined apriori and logistic regression approach, we obtained a high recall performance (i.e., the ratio of correctly predicted preferences compared with all predicted preferences and nonpreferences) and high precision (i.e., the ratio of correctly predicted rules with respect to the rules predicted to be true) of 80.2% and 79.2%, respectively. The recommender system successfully provides guidance on how to best tailor the preference items asked of residents and can support preference capture in busy clinical environments, contributing to the feasibility of delivering person-centered care.

  3. A Multiagent Evolutionary Algorithm for the Resource-Constrained Project Portfolio Selection and Scheduling Problem

    Directory of Open Access Journals (Sweden)

    Yongyi Shou

    2014-01-01

    Full Text Available A multiagent evolutionary algorithm is proposed to solve the resource-constrained project portfolio selection and scheduling problem. The proposed algorithm has a dual level structure. In the upper level a set of agents make decisions to select appropriate project portfolios. Each agent selects its project portfolio independently. The neighborhood competition operator and self-learning operator are designed to improve the agent’s energy, that is, the portfolio profit. In the lower level the selected projects are scheduled simultaneously and completion times are computed to estimate the expected portfolio profit. A priority rule-based heuristic is used by each agent to solve the multiproject scheduling problem. A set of instances were generated systematically from the widely used Patterson set. Computational experiments confirmed that the proposed evolutionary algorithm is effective for the resource-constrained project portfolio selection and scheduling problem.

    In nurse and in medicine courses, the use of reflective portfolios as a pedagogical tool is becoming a common practice; in the last years, this practice has gradually migrated from paper-based to electronic-based portfolios. Current approaches for reflective e-portfolios, however, do not widely operate at outdoor sites, where data networks are limited or nonexistent. Considering that many of the activities related to nurse and medicine courses relate to professional practices conducted in such conditions, these network shortcomings restrict the adoption of e-portfolios. The present study describes the requirements specification, design, implementation, and evaluation of the Ubiquitous Reflective E-Portfolio Architecture, a solution proposed to support the development of systems based on mobile and wired access for both online and offline operation. We have implemented a prototype named Professional Practice Module to evaluate the Ubiquitous Reflective E-Portfolio Architecture; the module was based on requirements observed during the professional practice, the paper-based portfolio in use, and related learning meetings in the Medicine Course of a Brazilian University. The evaluation of the system was carried out with a learning group of 2nd year students of the medicine course, who answered to extensive evaluation questionnaires. The prototype proved to be operational in the activities of the professional practice of the Medicine Course object of the study, including homework tasks, patient care, data sharing, and learning meetings. It also demonstrated to be versatile with respect to the availability of the computer network that, many times, was not accessible. Moreover, the students considered the module useful and easy to use, but pointed out difficulties about the keyboard and the display sizes of the netbook devices, and about their operational system. Lastly, most of the students declared preference for the electronic Professional Practice Module in internal

    The aim is to use the research portfolio evaluation protocol developed by HSL to evaluate the Probabilistic Safety Assessment (PSA) portfolio, both to draw conclusions about the PSA portfolio and as a pilot study to show the suitability of the evaluation protocol. The objectives of the work are: (1) To collect sufficient information to carry out a preliminary review of the portfolio; (2) o produce a plan of work detailing the time and costs to carry out a full evaluation of the PSA portfolio; (3) to evaluate the PSA portfolio of research; (4) to produce a report of the evaluation of the PSA portfolio; (5) if necessary, to make changes to the methodology in light of the experience gained in the evaluation of the PSA research portfolio. This report completes objectives 1 and 2. It details the plan of work for the evaluation of the PSA research portfolio. The plan has shown that the evaluation of the PSA research portfolio has many difficulties to overcome. It is suitable as a pilot study to show the suitability of the portfolio evaluation protocol and will provide valuable information that can be used to improve it. The evaluation of the PSA portfolio will require a considerable amount of time and effort to complete. The task analysis has shown it to be of the order of Pound Sterling 25k and to take two months to complete after this preliminary data collection. The plan to evaluate the PSA research portfolio detailed in this report should be carried out and the lessons learned by carrying out this pilot study should be used to improve the evaluation protocol

    Maurer, S M; Hogg, T; Huberman, B A

    2001-12-17

    Quantum computation holds promise for the solution of many intractable problems. However, since many quantum algorithms are stochastic in nature they can find the solution of hard problems only probabilistically. Thus the efficiency of the algorithms has to be characterized by both the expected time to completion and the associated variance. In order to minimize both the running time and its uncertainty, we show that portfolios of quantum algorithms analogous to those of finance can outperform single algorithms when applied to the NP-complete problems such as 3-satisfiability.

    2014-01-01

    As health professionals, nurses are responsible for staying abreast of current professional knowledge and managing their own career, professional growth and development, and ideally, practices to support these activities should start during their student years. Interest in electronic or eportfolios is gathering momentum as educationalists explore their potential as a strategy for fostering lifelong learning and enhancing on-going personal and professional development. In this paper, we present an overview of e-portfolios and their application to nurse education, highlighting potential benefits and considerations of useage. We argue that the e-portfolio can represent an authentic means of assessing cognitive, reflective and affective skills. Furthermore, the e-portfolio provides a means through which nurses can record and provide evidence of skills, achievements, experience, professional development and on-going learning, not only for themselves, but for the information and scrutiny of registration boards, employers, managers and peers.

    International medical electives are well-accepted in medical education, with the flow of students generally being North-South. In this article we explore the learning outcomes of Rwandan family medicine residents who completed their final year elective in South Africa. We compare the learning outcomes of this South-South elective to those of North-South electives from the literature. In-depth interviews were conducted with Rwandan postgraduate family medicine residents who completed a 4-week elective in South Africa during their final year of training. The interviews were thematically analysed in an inductive way. The residents reported important learning outcomes in four overarching domains namely: medical, organisational, educational, and personal. The learning outcomes of the residents in this South-South elective had substantial similarities to findings in literature on learning outcomes of students from the North undertaking electives in the Southern hemisphere. Electives are a useful learning tool, both for Northern students, and students from universities in the South. A reciprocity-framework is needed to increase mutual benefits for Southern universities when students from the North come for electives. We suggest further research on the possibility of supporting South-South electives by Northern colleagues.

    Full Text Available The use of e-portfolio becomes more common learning and student assessment; and this is due to the need for teachers to enhance students’ autonomy. The use of e-portfolio helps students to reflect on their own learning process. Lectures to large groups should not be limited only to classes, but must foster active learning, and in this regard, the introduction of the e-portfolio is a good tool because it stimulates collaborative and cooperative work among students and in turn encourages feedback with the teacher. To apply active methodologies during 2014-15 has been introduced in the course of the preparation of Linear Algebra comprehensive e-portfolio. To prepare the work of the e-portfolio the teacher had to clearly define the objectives that must be achieved by the students, and has had to plan in an understandable manner the tasks that the students can work independently outside the classroom. For the realization of the e-portfolio have been used different platforms. Each third of the students worked with a different platform, through AteneaLabs that it has provided templates in order that each student make their own e-portfolio, as well as it provide all necessary manuals. The platforms used were: Mahara, Exabis, WordPress and Google Sites. Formative assessment of the e-portfolio has been made from different rubrics defined in in the course syllabus and known by students since the beginning of the course.

    An excellent demonstration of how meaningful and valuable conferences devoted to the topic of project and portfolio management in the pharmaceutical industry can be, was given at an event organized in Barcelona, September 2008. Thus, over this 2-day meeting the delegates were updated on the state of the art in this wide-reaching area from speakers representing an array of companies; from small, relatively new players, via mid-sized, to established large and big pharmas. One common theme that emerged was the importance of assessing the value of drug projects as correctly as possible, especially under the current financial climate and the many challenges facing the industry. Furthermore, experiences from constructing portfolios with the aim to minimize risk and maximize return on investment were shared alongside mathematical approaches to obtain the data required for this purpose and accounts of the pleasures and hardships working in a global context and in partnership constellations.

    This article investigates whether a reflexive portfolio is instrumental in determining the level of acquisition of clinical competences in traumatology, a subject in the 5th year of the degree of medicine. A total of 131 students used the portfolio during their clinical rotation of traumatology. The students' portfolios were blind evaluated by four professors who annotated the existence (yes/no) of 23 learning outcomes. The reliability of the portfolio was moderate, according to the kappa index (0.48), but the evaluation scores between evaluators were very similar. Considering the mean percentage, 59.8% of the students obtained all the competences established and only 13 of the 23 learning outcomes (56.5%) were fulfilled by >50% of the students. Our study suggests that the portfolio may be an important tool to quantitatively analyze the acquisition of traumatology competences of medical students, thus allowing the implementation of methods to improve its teaching.

    2016-01-01

    A well-designed learning curve is essential for the acquisition of laparoscopic skills: but, are there risk factors that can derail the surgical method? From a review of the current literature on the learning curve in laparoscopic surgery, we identified learning curve components in video laparoscopic cholecystectomy; we suggest a learning curve model that can be applied to assess the progress of general surgical residents as they learn and master the stages of video laparoscopic cholecystectomy regardless of type of patient. Electronic databases were interrogated to better define the terms "surgeon", "specialized surgeon", and "specialist surgeon"; we surveyed the literature on surgical residency programs outside Italy to identify learning curve components, influential factors, the importance of tutoring, and the role of reference centers in residency education in surgery. From the definition of acceptable error, self-efficacy, and error classification, we devised a learning curve model that may be applied to training surgical residents in video laparoscopic cholecystectomy. Based on the criteria culled from the literature, the three surgeon categories (general, specialized, and specialist) are distinguished by years of experience, case volume, and error rate; the patients were distinguished for years and characteristics. The training model was constructed as a series of key learning steps in video laparoscopic cholecystectomy. Potential errors were identified and the difficulty of each step was graded using operation-specific characteristics. On completion of each procedure, error checklist scores on procedure-specific performance are tallied to track the learning curve and obtain performance indices of measurement that chart the trainee's progress. The concept of the learning curve in general surgery is disputed. The use of learning steps may enable the resident surgical trainee to acquire video laparoscopic cholecystectomy skills proportional to the instructor

    2009-12-01

    A portfolio is used to mentor and assess students' clinical performance at the workplace. However, students and raters often perceive the portfolio as a time-consuming instrument. In this study, we investigated whether assessment during medical internship by a portfolio can combine reliability and feasibility. The domain-oriented reliability of 61 double-rated portfolios was measured, using a generalisability analysis with portfolio tasks and raters as sources of variation in measuring the performance of a student. We obtained reliability (Phi coefficient) of 0.87 with this internship portfolio containing 15 double-rated tasks. The generalisability analysis showed that an acceptable level of reliability (Phi = 0.80) was maintained when the amount of portfolio tasks was decreased to 13 or 9 using one and two raters, respectively. Our study shows that a portfolio can be a reliable method for the assessment of workplace learning. The possibility of reducing the amount of tasks or raters while maintaining a sufficient level of reliability suggests an increase in feasibility of portfolio use for both students and raters.

    2017-09-01

    Full Text Available This paper discusses the findings of a research study concerning the use of e-portfolios to develop learners' autonomy and independence, from the perspectives of teachers and students participating in this study. The findings demonstrate many of the benefits of e-portfolio practice regarding learners’ increased sense of ownership, teacher and peer feedback, enriched learning experience at both individual and technological levels, enhanced opportunity for self-improvement and increased awareness of the learning process. Despite many positive aspects of e-portfolios use, the study reveals some challenges facing students, teachers and support staff, mainly connected with technical problems and Internet access, and the necessity for teachers and learners to change their roles to become more independent in the learning process. The author concludes that e-portfolio is a promising tool to stimulate and challenge students to become independent and self-regulated learners that should be implemented in English language learning at higher educational institutions.

    2013-09-04

    There is a need to provide more efficient surgical training methods for orthopaedic residents. E-learning could possibly increase resident surgical preparedness, confidence, and comfort for surgery. Using closed reduction and pinning of pediatric supracondylar humeral fractures as the index case, we hypothesized that e-learning could increase resident knowledge acquisition for case preparation in the operating room. An e-learning surgical training module was created on the Computer Enhanced Visual Learning platform. The module provides a detailed and focused road map of the procedure utilizing a multimedia format. A multisite prospective randomized controlled study design compared residents who used a textbook for case preparation (control group) with residents who used the same textbook plus completed the e-learning module (test group). All subjects completed a sixty-question test on the theory and methods of the case. After completion of the test, the control group then completed the module as well. All subjects were surveyed on their opinion regarding the effectiveness of the module after performing an actual surgical case. Twenty-eight subjects with no previous experience in this surgery were enrolled at four academic centers. Subjects were randomized into two equal groups. The test group scored significantly better (p < 0.001) and demonstrated competence on the test compared with the control group; the mean correct test score (and standard deviation) was 90.9% ± 6.8% for the test group and 73.5% ± 6.4% for the control group. All residents surveyed (n = 27) agreed that the module is a useful supplement to traditional methods for case preparation and twenty-two of twenty-seven residents agreed that it reduced their anxiety during the case and improved their attention to surgical detail. E-learning using the Computer Enhanced Visual Learning platform significantly improved preparedness, confidence, and comfort with percutaneous closed reduction and pinning of a

    Full Text Available In this paper we exploit the parametric portfolio optimization in the Brazilian market. Our data consists of monthly returns of 306 Brazilian stocks in the period between 2001 and 2013. We tested the model both in and out of sample and compared the results with the value and equal weighted portfolios and with a Markowitz based portfolio. We performed statistical inference in the parametric optimization using bootstrap techniques in order to build the parameters empirical distributions. Our results showed that the parametric optimization is a very efficient technique out of sample. It consistently showed superior results when compared with the VW, EW and Markowitz portfolios even when transaction costs were included. Finally, we consider the parametric approach to be very flexible to the inclusion of constraints in weights, transaction costs and listing and delisting of stocks.

    A reasonable assumption for the estimated new build market for the next 25 years is over 340 GWe net. The number of prospect countries is growing almost each day. To address this new build market, AREVA is developing a comprehensive portfolio of reactors intended to meet a wide range of power requirements and of technology choices. The EPR reactor is the flagship of the fleet. Intended for large power requirements, the four first EPRs are being built in Finland, France and China. Other countries and customers are in view, citing just two examples: the Usa where the U.S. EPR has been selected as the technology of choice by several U.S utilities; and the United Kingdom where the Generic Design Acceptance process of the EPR design submitted by AREVA and EDF is well under way, and where there is a strong will to have a plant on line in 2017. For medium power ranges, the AREVA portfolio includes a boiling water reactor and a pressurized water reactor which both offer all of the advantages of an advanced plant design, with excellent safety performance and competitive power generation cost: -) KERENA (1250+ MWe), developed in collaboration with several European utilities, and in particular with Eon; -) ATMEA 1 (1100+ MWe), a 3-loop evolutionary PWR which is being developed by AREVA and Mitsubishi. AREVA is also preparing the future and is deeply involved into Gen IV concepts. It has developed the ANTARES modular HTR reactor (pre-conceptual design completed) and is building upon its vast Sodium Fast Reactor experience to take part into the development of the next prototype.

    Toma, Aida; Leoni-Aubin, Samuela

    2015-01-01

    The presence of outliers in financial asset returns is a frequently occurring phenomenon which may lead to unreliable mean-variance optimized portfolios. This fact is due to the unbounded influence that outliers can have on the mean returns and covariance estimators that are inputs in the optimization procedure. In this paper we present robust estimators of mean and covariance matrix obtained by minimizing an empirical version of a pseudodistance between the assumed model and the true model underlying the data. We prove and discuss theoretical properties of these estimators, such as affine equivariance, B-robustness, asymptotic normality and asymptotic relative efficiency. These estimators can be easily used in place of the classical estimators, thereby providing robust optimized portfolios. A Monte Carlo simulation study and applications to real data show the advantages of the proposed approach. We study both in-sample and out-of-sample performance of the proposed robust portfolios comparing them with some other portfolios known in literature.

    Rational investors perceive correctly the value of financial information. Investment in information is therefore rewarded with a higher Sharpe ratio. Overconfident investors overstate the quality of their own information, and thus attain a lower Sharpe ratio. We contrast the implications of the two models using a unique survey of customers of an Italian leading bank with portfolio data and measures of financial information. We find that the portfolio Sharpe ratio is negatively associated with...

    2014-06-01

    Full Text Available The paper proposes the fundamental portfolio of securities. This portfolio is an alternative for the classic Markowitz model, which combines fundamental analysis with portfolio analysis. The method’s main idea is based on the use of the TMAI1 synthetic measure and, in limiting conditions, the use of risk and the portfolio’s rate of return in the objective function. Different variants of fundamental portfolio have been considered under an empirical study. The effectiveness of the proposed solutions has been related to the classic portfolio constructed with the help of the Markowitz model and the WIG20 market index’s rate of return. All portfolios were constructed with data on rates of return for 2005. Their effectiveness in 2006- 2013 was then evaluated. The studied period comprises the end of the bull market, the 2007-2009 crisis, the 2010 bull market and the 2011 crisis. This allows for the evaluation of the solutions’ flexibility in various extreme situations. For the construction of the fundamental portfolio’s objective function and the TMAI, the study made use of financial and economic data on selected indicators retrieved from Notoria Serwis for 2005.

    Full Text Available This study focuses on the assessment of speaking skills with reference to young learners. This is achieved by using an alternative method of assessment, namely portfolios. The general aim is to introduce learners’ to portfolio assessment of their speaking skills and to promote further learning and autonomy making, thus, learning and assessment coexist in a non-threatening mode. Three methodological tools are used for this research; a needs analysis questionnaire addressing the pupils��� needs of the fifth grade of a Greek primary school, the European Portfolio of Languages (ELP - used in tandem with the oral portfolio Dossier - and a final evaluation questionnaire given to the pupils after the completion of the oral portfolio project. Based on the statistical analysis of pupils’ evaluation results and the teacher’s observation throughout the school year, it is evident that the oral portfolio denotes a time-consuming and laborious assessment process. Nevertheless, the pupils see it as an interesting experience and are willing to use it again in the future. In conclusion, students’ portfolios are an innovative method of assessment that can actually promote the development of speaking skills and young learners’ metacognitive strategies in the EFL classroom, and raise their interest in learning.

    To examine the effectiveness of an asynchronous learning tool consisting of web-based lectures for trainees covering major topics pertinent to pediatric emergency medicine (PEM) and to assess resident and student evaluation of this mode of education. PEM faculty and fellows created a 21-lecture, web-based curriculum. These 20-minute online lectures used Microsoft PowerPoint with the voice-over feature. A 75-question test was created to assess the effectiveness of the web-based learning model, administered online before and after the rotation in the pediatric emergency department (PED). All fourth-year medical students and residents (across all specialties) rotating through the PED were required to complete 10 of the 21 lectures during their 1-month rotation. The main outcome variable was difference in score between pre- and post-rotation tests of participants who viewed no lectures and those who viewed at least one lecture. Evaluation of the program was assessed by anonymous survey using 5-point discrete visual analog scales. Responses of 4 or 5 were considered positive for analysis. One hundred eleven residents and fourth-year medical students participated in the program. An initial 32 completed testing before implementation of the on-line lectures (March 2007-August 2007), and another five did not complete the on-line lectures after implementation (September 2007-February 2008). Seventy-one completed testing and on-line lectures, and all but three completed at least 10 on-line lectures during their rotation. Fourteen of 111 trainees did not complete the pre- or post-test (including two who viewed the lectures). The mean change in score was a 1% improvement from pre-test to post-test for trainees who viewed no lectures and a 6.2% improvement for those who viewed the lectures (mean difference = 5.2%, 95% confidence interval = 2.5% to 7.9%). In the linear regression model, the estimate of the coefficient was 0.43 (p lecture viewed, post-test score rose by 0

    The Bregman divergence of two probability vectors is a stronger form of the f-divergence introduced by Csiszar. Two versions of the Bregman universal portfolio are presented by exploiting the mean-value theorem. The explicit form of the Bregman universal portfolio generated by a function of a convex polynomial is derived and studied empirically. This portfolio can be regarded as another generalized of the well-known Helmbold portfolio. By running the portfolios on selected stock-price data sets from the local stock exchange, it is shown that it is possible to increase the wealth of the investor by using the portfolios in investment.

    Data regarding knowledge acquisition during residency training are sparse. Predictors of theoretical learning quality, academic career achievements and evidence-based medical practice during residency are unknown. We performed a cross-sectional study on residents and attending physicians across several residency programs in 2 French faculties of medicine. We comprehensively evaluated the information-seeking behavior (I-SB) during residency using a standardized questionnaire and looked for independent predictors of theoretical learning quality, academic career achievements, and evidence-based medical practice among I-SB components using multivariate logistic regression analysis. Between February 2013 and May 2013, 338 fellows and attending physicians were included in the study. Textbooks and international medical journals were reported to be used on a regular basis by 24% and 57% of the respondents, respectively. Among the respondents, 47% refer systematically (4.4%) or frequently (42.6%) to published guidelines from scientific societies upon their publication. The median self-reported theoretical learning quality score was 5/10 (interquartile range, 3-6; range, 1-10). A high theoretical learning quality score (upper quartile) was independently and strongly associated with the following I-SB components: systematic reading of clinical guidelines upon their publication (odds ratio [OR], 5.55; 95% confidence interval [CI], 1.77-17.44); having access to a library that offers the leading textbooks of the specialty in the medical department (OR, 2.45, 95% CI, 1.33-4.52); knowledge of the specialty leading textbooks (OR, 2.12; 95% CI, 1.09-4.10); and PubMed search skill score ≥5/10 (OR, 1.94; 95% CI, 1.01-3.73).

    Introduction Great demands have been placed on disaster medicine educators. There is a need to develop innovative methods to educate Emergency Physicians in the ever-expanding body of disaster medicine knowledge. The authors sought to demonstrate that video-based learning (VBL) could be a promising alternative to traditional learning methods for teaching disaster medicine core competencies. Hypothesis/Problem The objective was to compare VBL to traditional lecture (TL) for instructing Emergency Medicine residents in the American College of Emergency Physicians (ACEP; Irving, Texas USA) disaster medicine core competencies of patient triage and decontamination. A randomized, controlled pilot study compared two methods of instruction for mass triage, decontamination, and personal protective equipment (PPE). Emergency Medicine resident learning was measured with a knowledge quiz, a Likert scale measuring comfort, and a practical exercise. An independent samples t-test compared the scoring of the VBL with the TL group. Twenty-six residents were randomized to VBL (n=13) or TL (n=13). Knowledge score improvement following video (14.9%) versus lecture (14.1%) did not differ significantly between the groups (P=.74). Comfort score improvement also did not differ (P=.64) between video (18.3%) and lecture groups (15.8%). In the practical skills assessment, the VBL group outperformed the TL group overall (70.4% vs 55.5%; Plearning vs traditional lecture for instructing emergency medicine residents in disaster medicine principles of mass triage, decontamination, and personal protective equipment.

    2005-01-01

    Globally, very few college or university chemistry courses incorporate toxicology although public perception of chemicals and the chemical industry as threats to health and the environment has had an adverse effect on chemistry and on the use of its products. The International Union for Pure and Applied Chemistry (IUPAC) through its Commission on Toxicology recognized this and, with the support of the Committee on the Teaching of Chemistry has used the IUPAC web site to promote distance learning in toxicology for chemists. After preparation of a thoroughly refereed consensus Glossary of Terms for Chemists of Terms Used in Toxicology, a textbook Fundamental Toxicology for Chemists and a set of educational modules entitled Essential Toxicology were compiled and put through the normal thorough review procedure of IUPAC before being approved by the organization. There is now an additional Glossary of Terms Used in Toxicokinetics. The modules are freely downloadable in Adobe PDF format and are designed to be used both by educators and by students. Educators are asked to select whatever is appropriate to their students and to use the material as they wish, adding content specifically relevant to their circumstances. For self-study, the web modules have self-assessment questions and model answers. Currently the original Glossary for Chemists of Terms Used in Toxicology is being revised and it is expected that this will lead to further developments. The currently available components of the IUPAC programme may be accessed through the IUPAC website at the Subcommittee on Toxicology and Risk Assessment page: http://www.iupac.org/divisions/VII/VII.C.2/index.html

    Full Text Available Purpose While it is known that effective clinical education requires active involvement of its participants, regular feedback, communication skills and interprofessional training, limited studies have been conducted in Korea that demonstrate how pre-residency trainees acquire their core clinical skills. This is a cross-sectional study of interns and students across a third-tier university hospital in Korea to examine where and when they acquire core clinical skills. Methods A total of 74 students and 91 interns were asked to participate in a closed-ended questionnaire, and 50 participants (20 students and 30 interns were involved in semistructured individual interviews. The questionnaire was based on the Accreditation Council for Graduate Medical Education core competencies. Results The majority of core clinical skills were acquired during their rotations in emergency medicine, general surgery, and cardiothoracic surgery. The semistructured interviews revealed that these departments required their trainees to be highly involved and analytical, and participate in clinical discourse. Conclusion The common factor among the three departments is an environment in which trainees are highly involved in clinical duties, and are expected to make first-contact patient encounters, participate in clinical discourse, interpret investigative results and arrive at their own conclusions. Work-based learning appear to be key to the trends observed, and further study is warranted to determine whether these findings are indicative of true acquisition of clinical competence.

    Investors wish to achieve the target rate of return at the minimum level of risk in their investment. Portfolio optimization is an investment strategy that can be used to minimize the portfolio risk and can achieve the target rate of return. The mean-variance model has been proposed in portfolio optimization. The mean-variance model is an optimization model that aims to minimize the portfolio risk which is the portfolio variance. The objective of this study is to construct the optimal portfolio using the mean-variance model. The data of this study consists of weekly returns of 20 component stocks of FTSE Bursa Malaysia Kuala Lumpur Composite Index (FBMKLCI). The results of this study show that the portfolio composition of the stocks is different. Moreover, investors can get the return at minimum level of risk with the constructed optimal mean-variance portfolio.

    To evaluate the perception of postgraduate residents about the clinical educational environment and to investigate the association of their perception with different specialities and years of residency. The study was conducted in August 2016 at The Children's Hospital, Lahore, Pakistan, and comprised postgraduate residents who were asked to complete postgraduate hospital educational environment measure questionnaire. The residents' individual perception scores were calculated and the means of both individual domain and global score of the questionnaire were compared by different specialities and different levels of residency training year. SPSS 20 was used for statistical analysis. Of the 160 residents who completed the questionnaire, 114(71.3%) were related to paediatric medicine. The residents perceived their educational environment positive with a global mean score of 88.16±14.18. Autonomy and teaching were rated most highly by paediatric diagnostic residents, i.e. 32.23±8.148 and 36.23±9.010, respectively. Social support was rated the highest by paediatric surgery residents 24.36±4.653. There was no significant difference of perception between different specialities (p=0.876) or different years of residency (p=0.474). Postgraduate hospital educational environment measure can be used to identify areas of strengths and weaknesses in a hospital environment. Educational environment of study site was more positive than negative.

  2. Deformed exponentials and portfolio selection

    Rodrigues, Ana Flávia P.; Guerreiro, Igor M.; Cavalcante, Charles Casimiro

    In this paper, we present a method for portfolio selection based on the consideration on deformed exponentials in order to generalize the methods based on the gaussianity of the returns in portfolio, such as the Markowitz model. The proposed method generalizes the idea of optimizing mean-variance and mean-divergence models and allows a more accurate behavior for situations where heavy-tails distributions are necessary to describe the returns in a given time instant, such as those observed in economic crises. Numerical results show the proposed method outperforms the Markowitz portfolio for the cumulated returns with a good convergence rate of the weights for the assets which are searched by means of a natural gradient algorithm.

    The problem of portfolio optimization is one of the most important issues in asset management. We here propose a new dynamic portfolio strategy based on the time-varying structures of MST networks in Chinese stock markets, where the market condition is further considered when using the optimal portfolios for investment. A portfolio strategy comprises two stages: First, select the portfolios by choosing central and peripheral stocks in the selection horizon using five topological parameters, namely degree, betweenness centrality, distance on degree criterion, distance on correlation criterion and distance on distance criterion. Second, use the portfolios for investment in the investment horizon. The optimal portfolio is chosen by comparing central and peripheral portfolios under different combinations of market conditions in the selection and investment horizons. Market conditions in our paper are identified by the ratios of the number of trading days with rising index to the total number of trading days, or the sum of the amplitudes of the trading days with rising index to the sum of the amplitudes of the total trading days. We find that central portfolios outperform peripheral portfolios when the market is under a drawup condition, or when the market is stable or drawup in the selection horizon and is under a stable condition in the investment horizon. We also find that peripheral portfolios gain more than central portfolios when the market is stable in the selection horizon and is drawdown in the investment horizon. Empirical tests are carried out based on the optimal portfolio strategy. Among all possible optimal portfolio strategies based on different parameters to select portfolios and different criteria to identify market conditions, 65% of our optimal portfolio strategies outperform the random strategy for the Shanghai A-Share market while the proportion is 70% for the Shenzhen A-Share market.

Only stocks were selected for the examined sample from all the asset classes. Stocks in each portfolio are put together according to predefined criteria. All stocks were selected from Dow Jones Industrial Average (DJIA index which serves as a benchmark, too. Portfolios were compared based on their risk and return profiles. The results of this work will provide general recommendations on the optimal approach to choose securities for an investor’s portfolio.

    Most portfolio selection rules based on the sample mean and covariance matrix perform poorly out-of-sample. Moreover, there is a growing body of evidence that such optimization rules are not able to beat simple rules of thumb, such as 1/N. Parameter uncertainty has been identified as one major....... While most of the diversification benefits are preserved, the parameter estimation problem is alleviated. We conduct out-of-sample back-tests to show that in most cases different well-established portfolio selection rules applied on the reduced asset universe are able to improve alpha relative...

    A geometric analysis of return time series, performed in the past, implied that most of the systematic information in the market is contained in a space of small dimension. Here we have explored subspaces of this space to find out the relative performance of portfolios formed from companies that have the largest projections in each one of the subspaces. As expected, it was found that the best performance portfolios are associated with some of the small eigenvalue subspaces and not to the dominant dimensions. This is found to occur in a systematic fashion over an extended period (1990-2008).

    The main goal of the chapter is the presentation of the application project portfolio management approach to support development of e-Municipality and public administration information systems. The models of how people publish and utilize information on the web have been transformed continually. Instead of simply viewing on static web pages, users publish their own content through blogs and photo- and video-sharing slides. Analysed in this chapter, ICT (Information Communication Technology) projects for municipalities cover the mixture of the static web pages, e-Government information systems, and Wikis. So, for the management of the ICT projects' mixtures the portfolio project management approach is proposed.

    qualitative research approach was employed. Documentary analysis was carried out covering 25 portfolios produced in the years 2008, 2009, and 2010 in the health policy course at the Federal University of Viçosa, Minas Gerais, Brazil, in order to verify if this method allowed the acquisition of the competencies: learning to be (acting with autonomy, good judgment, personal responsibility; learning to know (assimilating general and specific scientific and cultural knowledge, which will be complemented and updated in the course of life; learning to do (acquiring procedures that will be useful for facing life and work difficulties; and learning to live and work together (better understanding of others, the world, and their inter-relationships. RESULTS: Students became involved with the proposed activities, especially the management of information (active search, selection, critical analyses, reviews, syntheses, and evaluation of information. There was a gradual opening to critical thinking, integrating new dimensions to the initial vision held by students on the SUS, which moved from a focus on disease and healing to a focus on health and prevention, and from a vision of SUS as a theoretical model towards a view of SUS as a feasible project that is under construction. CONCLUSIONS: The use of portfolios has enabled the education of citizen-health professionals, with academic, pedagogical, and practical emphasis. This indicates that universities and teachers can turn to the development of decision-making capacities and reflective thinking by students

    Bernanke, Joel; McCommon, Benjamin

    2018-01-01

    Given many competing demands, psychotherapy training to competency is difficult during psychiatric residency. Good Psychiatric Management for borderline personality disorder (GPM) offers an evidence-based, simplified, psychodynamically informed framework for the outpatient management of patients with borderline personality disorder, one of the most challenging disorders psychiatric residents must learn to treat. In this article, we provide an overview of GPM, and show that training in GPM meets a requirement for training in supportive psychotherapy; builds on psychodynamic psychotherapy training; and applies to other severe personality disorders, especially narcissistic personality disorder. We describe the interpersonal hypersensitivity model used in GPM as a straightforward way for clinicians to collaborate with patients in organizing approaches to psychoeducation, treatment goals, case management, use of multiple treatment modalities, and safety. A modification of the interpersonal hypersensitivity model that includes intra-personal hypersensitivity can be used to address narcissistic problems often present in borderline personality disorder. We argue that these features make GPM ideally suited for psychiatry residents in treating their most challenging patients, provide clinical examples to illustrate these points, and report the key lessons learned by a psychiatry resident after a year of GPM supervision.

    2014-06-01

    To describe how patients with major depression in psychiatric outpatient care use the portfolio method and whether the method helps the patients to understand their depression. Major depressive disorder is an increasing problem in society. Learning about one's depression has been demonstrated to be important for recovery. If the goal is better understanding and management of depression, learning must proceed on the patient's own terms, based on the patient's previous understanding of their depression. Learning must be aligned with patient needs if it is to result in meaningful and useful understanding. Each patient's portfolio consisted of a binder. Inside the binder, there was a register with predetermined flaps and questions. The patients were asked to work with the questions in the sections that built the content in the portfolio. Individual interviews with patients (n = 5) suffering from major depression according to Diagnostic and Statistical Manual of Mental Disorders - Fourth Edition (DSM-IV) (American Psychiatric Association 1994) were repeatedly conducted between April 2008 and August 2009 in two psychiatric outpatient clinics in western Sweden. Data were analysed using latent content analysis. The results showed that the portfolio was used by patients as a management strategy for processing and analysis of their situation and that a portfolio's structure affects its usability. The patients use the portfolio for reflection on and confirmation of their progress, to create structure in their situation, as a management strategy for remembering situations and providing reminders of upcoming activities. Using a clearly structured care portfolio can enable participation and patient learning and help patients understand their depression. The portfolio method could provide a tool in psychiatric nursing that may facilitate patient understanding and increase self-efficacy. © 2013 John Wiley & Sons Ltd.

    The universal portfolio is an important investment strategy in a stock market where no stochastic model is assumed for the stock prices. The zero-gradient set of the objective function estimating the next-day portfolio which contains the reverse Kullback-Leibler order-alpha divergence is considered. From the zero-gradient set, the explicit, reverse Helmbold universal portfolio is obtained. The performance of the explicit, reverse Helmbold universal portfolio is studied by running them on some stock-price data sets from the local stock exchange. It is possible to increase the wealth of the investor by using these portfolios in investment.

  11. Robust Portfolio Optimization Using Pseudodistances

    Science.gov (United States)

    2015-01-01

    The presence of outliers in financial asset returns is a frequently occurring phenomenon which may lead to unreliable mean-variance optimized portfolios. This fact is due to the unbounded influence that outliers can have on the mean returns and covariance estimators that are inputs in the optimization procedure. In this paper we present robust estimators of mean and covariance matrix obtained by minimizing an empirical version of a pseudodistance between the assumed model and the true model underlying the data. We prove and discuss theoretical properties of these estimators, such as affine equivariance, B-robustness, asymptotic normality and asymptotic relative efficiency. These estimators can be easily used in place of the classical estimators, thereby providing robust optimized portfolios. A Monte Carlo simulation study and applications to real data show the advantages of the proposed approach. We study both in-sample and out-of-sample performance of the proposed robust portfolios comparing them with some other portfolios known in literature. PMID:26468948

  14. Does health affect portfolio choice?

    Science.gov (United States)

    Love, David A; Smith, Paul A

    2010-12-01

    A number of recent studies find that poor health is empirically associated with a safer portfolio allocation. It is difficult to say, however, whether this relationship is truly causal. Both health status and portfolio choice are influenced by unobserved characteristics such as risk attitudes, impatience, information, and motivation, and these unobserved factors, if not adequately controlled for, can induce significant bias in the estimates of asset demand equations. Using the 1992-2006 waves of the Health and Retirement Study, we investigate how much of the connection between health and portfolio choice is causal and how much is due to the effects of unobserved heterogeneity. Accounting for unobserved heterogeneity with fixed effects and correlated random effects models, we find that health does not appear to significantly affect portfolio choice among single households. For married households, we find a small effect (about 2-3 percentage points) from being in the lowest of five self-reported health categories. Copyright © 2009 John Wiley & Sons, Ltd.

    2004-01-01

    Full Text Available Many and varied methods of assessment are used to evaluate undergraduate physiotherapy students. Different modes of assessment occur as a result of contrasting educational theories and because the purpose of assessment is variable. In this era of performance assessment related to  the students’ mastery of the core curriculum, portfolios can enhance the assessment process by revealing a range of skills and understandings. This fits snugly into the physiotherapy curriculum for undergraduate continuous assessment purposes. Portfolio assessment can facilitate more reflection on students’ learning, more ownership of learning and more awareness of self-development. This supports the South African Qualifications Authority’s objective for higher education of reflection and life-long learning in our students. This article presents discussion on the use of portfolios in physiotherapy student learning and assessment in clinical practice.

    We evaluated a newly designed electronic portfolio (e-Portfolio) that provided quantitative evaluation of surgical skills. Medical students at the University of Seville used the e-Portfolio on a voluntary basis for evaluation of their performance in undergraduate surgical subjects. Our new web-based e-Portfolio was designed to evaluate surgical practical knowledge and skills targets. Students recorded each activity on a form, attached evidence, and added their reflections. Students self-assessed their practical knowledge using qualitative criteria (yes/no), and graded their skills according to complexity (basic/advanced) and participation (observer/assistant/independent). A numerical value was assigned to each activity, and the values of all activities were summated to obtain the total score. The application automatically displayed quantitative feedback. We performed qualitative evaluation of the perceived usefulness of the e-Portfolio and quantitative evaluation of the targets achieved. Thirty-seven of 112 students (33%) used the e-Portfolio, of which 87% reported that they understood the methodology of the portfolio. All students reported an improved understanding of their learning objectives resulting from the numerical visualization of progress, all students reported that the quantitative feedback encouraged their learning, and 79% of students felt that their teachers were more available because they were using the e-Portfolio. Only 51.3% of students reported that the reflective aspects of learning were useful. Individual students achieved a maximum of 65% of the total targets and 87% of the skills targets. The mean total score was 345 ± 38 points. For basic skills, 92% of students achieved the maximum score for participation as an independent operator, and all achieved the maximum scores for participation as an observer and assistant. For complex skills, 62% of students achieved the maximum score for participation as an independent operator, and 98% achieved

    Full Text Available An E-Portfolio Assessment Management System (EAMS can be an innovative tool that provides students with flexible opportunities to demonstrate the acquisition of skills and abilities in an outcome-based institution. The system has been developed and used for the past ten years to create, reflect, revise, and structure students’ work. It is a repository management system that facilitates collecting, sharing, and presenting artifacts of student learning outcomes via a digital medium. Therefore, it provides students with flexible opportunities to demonstrate the acquisition of skills and abilities to demonstrate growth of achieving learning outcomes. The rationale of the EAMS is to allow students to demonstrate competences and reflect upon experiences to improve their learning and career readiness; hence, they are accountable for their learning. The system was built around two defined set of learning outcomes: institutionally agreed upon set of learning outcomes, and learning objectives that are related to major requirements. The purpose of this study is to analyze students’ perceptions and attitudes when using an e-portfolio to support their employment opportunities. The participants were 217 students in the College of Technological Innovation. The students reported that the developing of e-portfolios was extremely helpful. The results showed that students have positive opinions about using e-portfolios as a beneficial tool to support their readiness for employment; they believe an e-portfolio increases their confidence to find a job in the IT field because it can allow them to showcase artifacts that demonstrate competencies and reflect upon experiences, and they can provide their supervisors during their industrial training with an e-resume that includes views of their actual work of what they have learned and are able to do when they complete their degree. Employers then can review e-portfolios to select prospective employees work readiness

It is helpful in estimating risk of an investor's portfolio, arosen from lack of information, uncertainty and incomplete knowledge of reality, which forbids a perfect prediction of future price changes. Despite of many advantages this tool is not known and not widely used among investors on Warsaw Stock Exchange. The main reason for abandoning this method is a high level of complexity and immense calculations. The aim of this paper is to introduce an automatic decision-making system, which allows a single investor to use complex methods of Modern Portfolio Theory (MPT). The key tool in MPT is an analysis of an empirical covariance matrix. This matrix, obtained from historical data, biased by such a high amount of statistical uncertainty, that it can be seen as random. By bringing into practice the ideas of Random Matrix Theory (RMT), the noise is removed or significantly reduced, so the future risk and return are better estimated and controlled. These concepts are applied to the Warsaw Stock Exchange Simulator {http://gra.onet.pl}. The result of the simulation is 18% level of gains in comparison with respective 10% loss of the Warsaw Stock Exchange main index WIG.

    This qualitative study was carried out between April and August 2007. It analyzed the use of portfolios in the academic community. A total of nine full-time professors and 119 students enrolled in their third semester were interviewed through a semi-structured interview. Content analysis was used to analyze data. Learning evaluations are seen as a verification of knowledge and efficacy of pedagogical method, and also as an incentive to study. Evaluations are procedural, that is, evaluation is continuous, or one-time, e.g. semester end tests. The portfolio is defined as a gradual and continuous evaluation tool. The faculty members and students need to accept the use of portfolios and evaluate the possibilities of this resource. This study is a first attempt to appraise the evaluation process of an undergraduate program, and the use of portfolios and other strategies needs to be consolidated in order to improve the educational process in undergraduate nursing programs.

  13. Portfolio optimization in electricity markets

    Liu, Min; Wu, Felix F.

    2007-01-01

    In a competitive electricity market, Generation companies (Gencos) face price risk and delivery risk that affect their profitability. Risk management is an important and essential part in the Genco's decision making. In this paper, risk management through diversification is considered. The problem of energy allocation between spot markets and bilateral contracts is formulated as a general portfolio optimization problem with a risk-free asset and n risky assets. Historical data of the PJM electricity market are used to demonstrate the approach. (author)

  14. Large deviations and portfolio optimization

    Science.gov (United States)

    Sornette, Didier

    Risk control and optimal diversification constitute a major focus in the finance and insurance industries as well as, more or less consciously, in our everyday life. We present a discussion of the characterization of risks and of the optimization of portfolios that starts from a simple illustrative model and ends by a general functional integral formulation. A major item is that risk, usually thought of as one-dimensional in the conventional mean-variance approach, has to be addressed by the full distribution of losses. Furthermore, the time-horizon of the investment is shown to play a major role. We show the importance of accounting for large fluctuations and use the theory of Cramér for large deviations in this context. We first treat a simple model with a single risky asset that exemplifies the distinction between the average return and the typical return and the role of large deviations in multiplicative processes, and the different optimal strategies for the investors depending on their size. We then analyze the case of assets whose price variations are distributed according to exponential laws, a situation that is found to describe daily price variations reasonably well. Several portfolio optimization strategies are presented that aim at controlling large risks. We end by extending the standard mean-variance portfolio optimization theory, first within the quasi-Gaussian approximation and then using a general formulation for non-Gaussian correlated assets in terms of the formalism of functional integrals developed in the field theory of critical phenomena.

    To determine 1) the feasibility of implementing an e-learning module on chronic low back pain (CLBP) in an older adult into an existing internal medicine residency curriculum and 2) the impact of this module on resident attitudes, confidence, knowledge, and clinical skills relating to CLBP. Participants were assigned to complete either the online module (N = 73) or the Yale Office-based curriculum on CLBP (N = 70). Attitudes, confidence, and knowledge were evaluated pre- and postintervention via survey. A retrospective blinded chart review of resident clinic encounters was conducted, wherein diagnosis codes and physical exam documentation were rated as basic or advanced. There was no improvement in overall knowledge scores in either group (60% average on both metrics). There were tendencies for greater improvements in the intervention group compared with controls for confidence in managing fibromyalgia (2.4 to 2.9 vs 2.5 to 2.5, P = 0.06) and leg length discrepancy (1.8 to 2.5 vs 1.5 to 1.9, P = 0.05). Those exposed to the online module also showed an increase in the percentage of physical exam documentation rated as advanced following the intervention (13% to 32%, P = 0.006), whereas the control group showed no change (14% to 12%, P = 0.68). An online module on CLBP in the older adult was a feasible addition to an existing curriculum for internal medicine residents. The module positively and substantively impacted resident clinical behaviors, as evidenced by enhanced sophistication in physical exam documentation; it also was associated with improved confidence in certain aspects of chronic pain management. © 2018 American Academy of Pain Medicine.

    In a recent paper Galluccio, Bouchaud and Potters demonstrated that a certain portfolio problem with a nonlinear constraint maps exactly onto finding the ground states of a long-range spin glass, with the concomitant nonuniqueness and instability of the optimal portfolios. Here we put forward geometric arguments that lead to qualitatively similar conclusions, without recourse to the methods of spin glass theory, and give two more examples of portfolio problems with convex nonlinear constraints.

    We develop a new framework for multivariate intertemporal portfolio choice that allows us to derive optimal portfolio implications for economies in which the degree of correlation across industries, countries, or asset classes is stochastic. Optimal portfolios include distinct hedging components against both stochastic volatility and correlation risk. We find that the hedging demand is typically larger than in univariate models, and it includes an economically significant covariance hedging...

  20. The national portfolio for postgraduate family medicine training in South Africa: a descriptive study of acceptability, educational impact, and usefulness for assessment.

    2013-07-25

    Since 2007 a portfolio of learning has become a requirement for assessment of postgraduate family medicine training by the Colleges of Medicine of South Africa. A uniform portfolio of learning has been developed and content validity established among the eight postgraduate programmes. The aim of this study was to investigate the portfolio's acceptability, educational impact, and perceived usefulness for assessment of competence. Two structured questionnaires of 35 closed and open-ended questions were delivered to 53 family physician supervisors and 48 registrars who had used the portfolio. Categorical and nominal/ordinal data were analysed using simple descriptive statistics. The open-ended questions were analysed with ATLAS.ti software. Half of registrars did not find the portfolio clear, practical or feasible. Workshops on portfolio use, learning, and supervision were supported, and brief dedicated time daily for reflection and writing. Most supervisors felt the portfolio reflected an accurate picture of learning, but just over half of registrars agreed. While the portfolio helped with reflection on learning, participants were less convinced about how it helped them plan further learning. Supervisors graded most rotations, suggesting understanding the summative aspect, while only 61% of registrars reflected on rotations, suggesting the formative aspects are not yet optimally utilised. Poor feedback, the need for protected academic time, and pressure of service delivery impacting negatively on learning. This first introduction of a national portfolio for postgraduate training in family medicine in South Africa faces challenges similar to those in other countries. Acceptability of the portfolio relates to a clear purpose and guide, flexible format with tools available in the workplace, and appreciating the changing educational environment from university-based to national assessments. The role of the supervisor in direct observations of the registrar and dedicated

    ePortfolios are frequently used to support continuing professional development (CPD) of rehabilitation professionals. Though this tool is now widely implemented in many professions by regulatory organisations, very few studies have investigated the use and impact among rehabilitation professionals. Implementation of comprehensive ePortfolios that are centred on the needs of rehabilitation professionals requires documenting their level of use and perceived outcomes. The objectives were to describe how occupational therapists use a mandatory ePortfolio that has been recently implemented by a regulatory organisation in Quebec (Canada) and the perceived outcomes of this requirement on continuing professional development and practice change. An online survey was sent to all registered occupational therapists in Quebec using the ePortfolio. The survey content was developed based on a literature review and expert consultation. Results were analysed using descriptive statistics. A total of 546 respondents completed the survey. Results show relatively high levels of ease and satisfaction with the tool, but a limited perception of the tool's impacts on the improvement of professional competencies and change in practices. Occupational therapists reported that use of the ePortfolio supports their engagement in CPD but has limited impact on practice. Promotion of work-based learning, team use and mentor support could increase its meaningfulness for professionals. Implications for Rehabilitation To improve attitudes and beliefs about benefits related to portfolio use, rehabilitation practitioners need a very clear understanding of the purpose and usefulness of a portfolio in clinical practice. Most of the respondents saw the ePortfolio as helping them develop and implement a continuing professional development plan and reflect on the changes needed in their practice. Portfolio use in teams and productive reflection should be promoted in order to target shared objectives for

  2. Portfolio Management with Stochastic Interest Rates and Inflation Ambiguity

    DEFF Research Database (Denmark)

    Munk, Claus; Rubtsov, Alexey Vladimirovich

    We solve a stock-bond-cash portfolio choice problem for a risk- and ambiguity-averse investor in a setting where the inflation rate and interest rates are stochastic. The expected inflation rate is unobservable, but the investor may learn about it from realized inflation and observed stock and bond...... prices. The investor is aware that his model for the observed inflation is potentially misspecified, and he seeks an investment strategy that maximizes his expected utility from real terminal wealth and is also robust to inflation model misspecification. We solve the corresponding robust Hamilton......-Jacobi-Bellman equation in closed form and derive and illustrate a number of interesting properties of the solution. For example, ambiguity aversion affects the optimal portfolio through the correlation of price level with the stock index, a bond, and the expected inflation rate. Furthermore, unlike other settings...

    Previous research has demonstrated that persons with early to moderate stage dementia are capable of leading small group activities for persons with more advanced dementia. In this study, we built upon this previous work by training residents in long-term care facilities to fill the role of group activity leaders using a Resident-Assisted Programming (RAP) training regimen. There were two stages to the program. In the first stage, RAP training was provided by researchers. In the second stage, RAP training was provided to residents by activities staff members of long-term care facilities who had been trained by researchers. We examine the effects of RAP implemented by researchers and by activities staff member on long-term care resident with dementia who took part in these RAP activities. We also examined effects produced by two types of small group activities: two Montessori-based activities and an activity which focuses on persons with more advanced dementia, based on the work of Jitka Zgola. Results demonstrate that levels of positive engagement seen in players during RAP (resident-led activities) were typically higher than those observed during standard activities programming led by site staff. In general, Montessori-Based Dementia Programming® produced more constructive engagement than Zgola-based programming (ZBP), though ZBP did increase a positive form of engagement involving observing activities with interest. In addition, RAP implemented by activities staff members produced effects that were, on the whole, similar to those produced when RAP was implemented by researchers. Implications of these findings for providing meaningful social roles for persons with dementia residing in long-term care, and suggestions for further research in this area, are discussed.

    Zhao, Ziping; Palomar, Daniel P.

    2018-05-01

    This paper considers the mean-reverting portfolio design problem arising from statistical arbitrage in the financial markets. We first propose a general problem formulation aimed at finding a portfolio of underlying component assets by optimizing a mean-reversion criterion characterizing the mean-reversion strength, taking into consideration the variance of the portfolio and an investment budget constraint. Then several specific problems are considered based on the general formulation, and efficient algorithms are proposed. Numerical results on both synthetic and market data show that our proposed mean-reverting portfolio design methods can generate consistent profits and outperform the traditional design methods and the benchmark methods in the literature.

  10. Exploring Students’ Attitudes and Beliefs Towards E-Portfolios and Technology in Education

    Directory of Open Access Journals (Sweden)

    2015-05-01

    Full Text Available This article reports on student teachers’ attitude towards technology in education and e-portfolio processes. Attitude is closely related to teachers’ beliefs and the later have been defined as second-order barriers. While an important effort has been made to overcome first-order barrier such as resources, training and support, it cannot be observed that technology has been successfully introduced in education. Therefore, second-order barriers such as attitudes and beliefs are being considered nowadays in order to address the lack of innovative use of technology by teachers. It has been argued that the introduction of technology has to be directed towards the empowerment of cognitive and high-level thinking skills and has to be used based on student-centred approaches. Building e-portfolios and helping students which grow and curate their own Personal Learning Environments (PLE are two approaches to go beyond technology-centered models. E-Portfolios are viewed as part of students’ PLE so social media are used to enhance both e-portfolio processes and students’ PLEs. The research is based on a survey in four groups of students at the local branch in Ibiza of the University of the Balearic Islands. The participants have previously built their e-portfolios with Web 2.0 tools during one semester. Students are asked to document their learning weekly and reflect on the change experienced in the way they think about educational issues. Students are also asked to use new tools and social media services to give evidence of their own learning. The survey is based on a Likert scale so as to be able to analyse the students’ attitude and beliefs towards their e-portfolio and technology in education. The results show that a generally positive attitude is developed by students. Conclusions highlight the slight difference in student teachers’ attitude between technology and specific e-portfolio processes.

    Electronic portfolios can be used to record user performance and achievements. Currently, clinical learning systems and in-service education systems lack integration of nurses' clinical performance records with their education or training outcomes. For nurses with less than 2 years' work experience (nursing postgraduate year), use of an electronic portfolio is essential. This study aimed to assess the requirements of using electronic portfolios in continuing nursing education for clinical practices. Fifteen nurses were recruited using a qualitative purposive sampling approach between April 2013 and May 2013. After obtaining participants' consent, data were collected in a conference room of the study hospital by one-on-one semistructured in-depth interviews. Through data analyses, the following five main themes related to electronic learning portfolios were identified: instant access to in-service education information, computerized nursing postgraduate year training manual, diversity of system functions and interface designs, need for sufficient computers, and protection of personal documents. Because electronic portfolios are beginning to be used in clinical settings, a well-designed education information system not only can meet the needs of nurses but also can facilitate their learning progress.

    The foundation upon which surgical residents are trained to work comprises more than just critical cognitive, clinical, and technical skill. In an environment where the synchronous application of expertise is vital to patient outcomes, the expectation for optimal functioning within a multidisciplinary team is extremely high. Studies have shown that for most residents, one of the most difficult milestones in the path to achieving professional expertise in a surgical career is overcoming the learning curve. This view point commentary provides a reflection from the two senior medical students who have participated in the Student-as-Teacher program developed by the Department of Anatomy at Mayo Clinic, designed to prepare students for their teaching assistant (TA) role in anatomy courses. Both students participated as TAs in a six week surgical anatomy course for surgical first assistant students offered by the School of Health Sciences at Mayo Clinic. Development of teaching skills, nontechnical leadership, communication, and assessment skills, are discussed in relation to their benefits in preparing senior medical students for surgical residency. © 2015 American Association of Anatomists.

    The introduction of a new domain of learning for Personal and Professional Skills in the medical program at the University of Auckland in New Zealand has involved the compilation of a portfolio for assessment. This departure from the traditional assessment methods predominantly used in the past has been challenging to design, introduce, and maintain as a relevant and authentic assessment method. We present the portfolio format along with the process for its introduction and appraise the challenges, strengths, and limitations of the approach within the context of the current literature. We then outline a cyclical model of evaluation used to monitor and fine-tune the portfolio tasks and implementation process, in response to student and assessor feedback. The portfolios have illustrated the level of insight, maturity, and synthesis of personal and professional qualities that students are capable of achieving. The Auckland medical program strives to foster these qualities in its students, and the portfolio provides an opportunity for students to demonstrate their reflective abilities. Moreover, the creation of a Personal and Professional Skills domain with the portfolio as its key assessment emphasizes the importance of reflective practice and personal and professional development and gives a clear message that these are fundamental longitudinal elements of the program.

    Full Text Available Tracking student learning outcomes within college courses is important for observing their academic preparation for future career. Many library and information education institutions are now encouraging the use of ePortfolio system to help students document their school achievements and better present themselves for future job seeking. This study examined the use of and reactions to the ePortforlio system of the Fu Jen Catholic University, launched in Fall, 2010. Qualitative and quantitative data were gathered during 2012 to analyze students’ experiences with and suggestions for the improvement of the ePortfolio system. 66 students’ self-reflections and 12 student interview data were gathered. An online survey based on the previous analyses was then developed and distributed to the LIS students who used the system. A total of 140 responses were gathered and used for quantitative analysis. Results of the study revealed that students’ reactions toward the ePortfolio system were positive. Students perceived the benefits of using ePortfolio in professional development and career placement. Peer influence encouraged the sharing of content. Students also highly agreed that longterm investment of time and use of external incentives were essential for promoting use of the ePortfolio system. It is also suggested that the functions of ePortfolio system needed to be enhanced in order to encourage more students’ use. [Article content in Chinese

    The academic portfolio has become an integral part of the promotions process. Creating and maintaining an academic portfolio in paper-based or web-based formats can be a cumbersome and time-consuming task. In this article, we describe an alternative way to efficiently organize an academic portfolio using a reference manager software, and discuss some of the afforded advantages. The reference manager software Papers (Mekentosj, Amsterdam, The Netherlands) was used to create an academic portfolio. The article outlines the key steps in creating and maintaining a digital academic portfolio. Using reference manager software (Papers), we created an academic portfolio that allows the user to digitally organize clinical, teaching, and research accomplishments in an indexed library enabling efficient updating, rapid retrieval, and easy sharing. To our knowledge, this is the first digital portfolio of its kind.

  18. Model Risk in Portfolio Optimization

    Directory of Open Access Journals (Sweden)

    David Stefanovits

    2014-08-01

    Full Text Available We consider a one-period portfolio optimization problem under model uncertainty. For this purpose, we introduce a measure of model risk. We derive analytical results for this measure of model risk in the mean-variance problem assuming we have observations drawn from a normal variance mixture model. This model allows for heavy tails, tail dependence and leptokurtosis of marginals. The results show that mean-variance optimization is seriously compromised by model uncertainty, in particular, for non-Gaussian data and small sample sizes. To mitigate these shortcomings, we propose a method to adjust the sample covariance matrix in order to reduce model risk.

  19. Strategic biopharmaceutical portfolio development: an analysis of constraint-induced implications.

    George, Edmund D; Farid, Suzanne S

    2008-01-01

    Optimizing the structure and development pathway of biopharmaceutical drug portfolios are core concerns to the developer that come with several attached complexities. These include strategic decisions for the choice of drugs, the scheduling of critical activities, and the possible involvement of third parties for development and manufacturing at various stages for each drug. Additional complexities that must be considered include the impact of making such decisions in an uncertain environment. Presented here is the development of a stochastic multi-objective optimization framework designed to address these issues. The framework harnesses the ability of Bayesian networks to characterize the probabilistic structure of superior decisions via machine learning and evolve them to multi-objective optimality. Case studies that entailed three- and five-drug portfolios alongside a range of cash flow constraints were constructed to derive insight from the framework where results demonstrate that a variety of options exist for formulating nondominated strategies in the objective space considered, giving the manufacturer a range of pursuable options. In all cases limitations on cash flow reduce the potential for generating profits for a given probability of success. For the sizes of portfolio considered, results suggest that naïvely applying strategies optimal for a particular size of portfolio to a portfolio of another size is inappropriate. For the five-drug portfolio the most preferred means for development across the set of optimized strategies is to fully integrate development and commercial activities in-house. For the three-drug portfolio, the preferred means of development involves a mixture of in-house, outsourced, and partnered activities. Also, the size of the portfolio appears to have a larger impact on strategy and the quality of objectives than the magnitude of cash flow constraint.

    Full Text Available Abstract In this paper, we consider the robust portfolio selection problem which has a data uncertainty described by the ( p , w $(p,w$ -norm in the objective function. We show that the robust formulation of this problem is equivalent to a linear optimization problem. Moreover, we present some numerical results concerning our robust portfolio selection problem.

    Sequential portfolio selection has attracted increasing interest in the machine learning and quantitative finance communities in recent years. As a mathematical framework for reinforcement learning policies, the stochastic multi-armed bandit problem addresses the primary difficulty in sequential decision-making under uncertainty, namely the exploration versus exploitation dilemma, and therefore provides a natural connection to portfolio selection. In this paper, we incorporate risk awareness into the classic multi-armed bandit setting and introduce an algorithm to construct portfolio. Through filtering assets based on the topological structure of the financial market and combining the optimal multi-armed bandit policy with the minimization of a coherent risk measure, we achieve a balance between risk and return.

    Full Text Available The study analyzes the improvement in generic competences through e-portfolio/PLE platform and didactic planning. The new version of the platform, Digital Folder, contains utilities for students and teachers and some PLE components that help the learning process through e-portfolios. Didactic planning is compared for students from the University of Vic and the University of Barcelona, with a total of 61 participants. A questionnaire has been applied for measuring the use of functions and how much these functions aid in the improvement of the generic competences (reflection, planning and selection of information. The results confirm that the most helpful functions for students are: the Schedule, the Academic tasks, the Teacher’s portfolio and Dialogue with the teacher. However, the implication of these functions in the improvement of the competences depends on didactic planning overall for reflection on learning.

  20. Educating doctors in the clinical workplace: unraveling the process of teaching and learning in the medical resident as teacher.

    In recent years, higher medical education has witnessed major changes in the structure and content of postgraduate medical training. Seven professional competencies have been described that address the medical doctors' ability to effectively communicate and transfer medical information, interact effectively and professionally, and demonstrate a good grasp of clinical knowledge and skills. Proficiency in didactic skills, however, is an important competency that has not received prominent attention. In the clinical setting, attending-physicians and medical residents are responsible for teaching. Consequently, several medical institutions have proposed the need for teacher training programs to improve the teaching skills of attending doctors and medical residents. The supporters of these programs believe that through teaching, medical doctors improve their individual professional and clinical problem-solving abilities. Hence, it is logical to assume that didactic skills' training would contribute to the professional development of doctors. In this paper, we re-examine the underlying theory of the didactic proficiency, how it relates to the clinical setting, and why it may be beneficial for the professional training of medical residents.
