    The relatively new specialty of Hospital Medicine in the USA is one of the fastest growing fields in internal medicine. Academic hospitalists are largely involved in the medical education of postgraduate residents and medical students. Little is known about the effectiveness of peer-to-peer teaching in internal medicine residency training programs and how the medical residents perceive its educational value in learning Hospital Medicine. The Hospitalist Huddle is a weekly educational activity newly established by our Hospitalist Division to facilitate the concept of peer-to-peer teaching. It requires medical residents to teach and educate their peers about the clinical topics related to Hospital Medicine. Faculty hospitalists serve as facilitators during the teaching sessions. A survey disseminated at the end of the first year of its implementation examined the residents' perception of the educational value of this new teaching activity. Most residents reported that they see the Huddle as a useful educational forum which may improve their skills in teaching, create a better educational and learning environment during their inpatient rotation, and improve their understanding of Hospital Medicine. Most residents also prefer that their peers, rather than faculty hospitalists, run the activity and do the teaching. The survey results support the notion that teaching and learning with flat hierarchies can be an appealing educational method to medical residents to help them understand Hospital Medicine during their medical wards rotation. Some areas need to be improved and others need to be continued and emphasized in order to make this novel educational activity grow and flourish in terms of its educational value and residents' satisfaction.

    United States academic hospitals have rapidly adopted the hospitalist model of care. Academic hospitalists have taken on much of the clinical and teaching responsibilities at many institutions, yet little is known about their academic productivity and promotion. We sought to discover the attitudes and attributes of academic hospitalists regarding mentorship, productivity, and promotion. We performed a web-based email survey of academic hospitalists consisting of 61 questions. Four hundred and twenty academic hospitalists. Demographic details, scholarly production, presence of mentorship and attitudes towards mentor, academic rank Two hundred and sixty-six (63%) of hospitalists responded. The majority were under 41 (80%) and had been working as hospitalists for 20% "protected" time, AOR = 1.92 (95% CI 1.00, 3.69), and 3) a better-than-average understanding of the criteria for promotion, AOR = 3.66 (95% CI 1.76, 7.62). A lack of mentorship was negatively associated with producing any peer-reviewed first author publications AOR = 0.43 (95% CI 0.23, 0.81); any non-peer reviewed publications AOR = 0.45 (95% CI 0.24, 0.83), and leading a teaching session at a national meeting AOR = 0.41 (95% CI 0.19, 0.88). Most hospitalists promoted to the level of associate professor had been first author on four to six peer-reviewed publications. Most academic hospitalists had not presented a poster at a national meeting, authored an academic publication, or presented grand rounds at their institution. Many academic hospitalists lacked mentorship and this was associated with a failure to produce scholarly activity. Mentorship may improve academic productivity among hospitalists.

    Medicine subspecialty consultation is becoming increasingly important in inpatient medicine. We conducted a survey study in which we examined hospitalist practices and attitudes regarding medicine subspecialty consultation. The survey instrument was developed by the authors based on prior literature and administered online anonymously to hospitalists at 4 academic medical centers in the United States. The survey evaluated 4 domains: (1) current consultation practices, (2) preferences regarding consultation, (3) barriers to and facilitating factors of effective consultation, and (4) a comparison between hospitalist-fellow and hospitalist-subspecialty attending interactions. One hundred twenty-two of 261 hospitalists (46.7%) responded. The majority of hospitalists interacted with fellows during consultation. Of those, 90.9% reported that in-person communication occurred during less than half of consultations, and 64.4% perceived pushback at least "sometimes " in their consult interactions. Participants viewed consultation as an important learning experience, preferred direct communication with the consulting service, and were interested in more teaching during consultation. The survey identified a number of barriers to and facilitating factors of an effective hospitalist-consultant interaction, which impacted both hospitalist learning and patient care. Hospitalists reported more positive experiences when interacting with subspecialty attendings compared to fellows with regard to multiple aspects of the consultation. The hospitalist-consultant interaction is viewed as important for both hospitalist learning and patient care. Multiple barriers and facilitating factors impact the interaction, many of which are amenable to intervention.

    To evaluate whether implementation of a geographic model of assigning hospitalists is feasible and sustainable in a large hospitalist program and assess its impact on provider satisfaction, perceived efficiency and patient outcomes. Pre (3 months) - post (12 months) intervention study conducted from June 2014 through September 2015 at a tertiary care medical center with a large hospitalist program caring for patients scattered in 4 buildings and 16 floors. Hospitalists were assigned to a particular nursing unit (geographic assignment) with a goal of having over 80% of their assigned patients located on their assigned unit. Satisfaction and perceived efficiency were assessed through a survey administered before and after the intervention. Geographic assignment percentage increased from an average of 60% in the pre-intervention period to 93% post-intervention. The number of hospitalists covering a 32 bed unit decreased from 8-10 pre to 2-3 post-intervention. A majority of physicians (87%) thought that geography had a positive impact on the overall quality of care. Respondents reported that they felt that geography increased time spent with patient/caregivers to discuss plan of care (p < 0.001); improved communication with nurses (p = 0.0009); and increased sense of teamwork with nurses/case managers (p < 0.001). Mean length of stay (4.54 vs 4.62 days), 30-day readmission rates (16.0% vs 16.6%) and patient satisfaction (79.9 vs 77.3) did not change significantly between the pre- and post-implementation period. The discharge before noon rate improved slightly (47.5% - 54.1%). Implementation of a unit-based model in a large hospitalist program is feasible and sustainable with appropriate planning and support. The geographical model of care increased provider satisfaction and perceived efficiency; it also facilitated the implementation of other key interventions such as interdisciplinary rounds.

    Pediatric hospital medicine (PHM) is moving toward becoming an American Board of Pediatrics (ABP) subspecialty, roughly a decade after its formal inception in 2003. Education has played a central role as the field has evolved. Hospitalists are needed to educate trainees, medical students, residents, fellows, and nurse practitioner and physician assistant students in inpatient pediatric practice. Continuous professional development is needed for hospitalists currently in practice to augment clinical skills, such as providing sedation and placing peripherally inserted central catheter lines, and nonclinical skills in areas such as quality improvement methodology, hospital administration, and health service research. To address the educational needs of the current and future state of PHM, additional training is now needed beyond residency training. Fellowship training will be essential to continue to advance the field of PHM as well as to petition the ABP for specialty accreditation. Training in using adult educational theory, curriculum, and assessment design are critical for pediatric hospitalists choosing to advance their careers as clinician-educators. Several venues are available for gaining advanced knowledge and skill as an educator. PHM clinician-educators are advancing the field of pediatric education as well as their own academic careers by virtue of the scholarly approach they have taken to designing and implementing curricula for unique PHM teaching situations. PHM educators are changing the educational paradigm to address challenges to traditional education strategies posed by duty hour restrictions and the increasing drive to shorten the duration of the hospitalization. By embracing learning with technology, such as simulation and e-learning with mobile devices, PHM educators can address these challenges as well as respond to learning preferences of millennial learners. The future for PHM education is bright. Copyright 2014, SLACK Incorporated.

    The last decade has brought significant changes to internal medicine clerkships through resident work-hour restrictions and the widespread adoption of hospitalists as medical educators. These key medical educators face competing demands for quality teaching and clinical service intensity. The study reported here was conducted to explore the relationship between clinical service intensity and teaching evaluations of hospitalists by internal medicine clerkship students. A retrospective correlation analysis of clinical service intensity and teaching evaluations of hospitalists by internal medicine clerkship students during the 2009 to 2013 academic years at Southern Illinois University School of Medicine was conducted. Internal medicine hospitalists who supervise the third-year inpatient experience for medical students during the 2009 to 2013 academic years participated in the study. Clinical service intensity data in terms of work relative value units (RVUs), patient encounters, and days of inpatient duty were collected for all members of the hospitalist service. Medical students rated hospitalists in the areas of patient rapport, enthusiasm about the profession, clinical skills, sharing knowledge and skills, encouraging the students, probing student knowledge, stimulating independent learning, providing timely feedback, providing constructive criticism, and observing patient encounters with students. Significant negative correlations between higher work RVU production, total patient encounters, duty days, and learner evaluation scores for enthusiasm about the profession, clinical skills, probing the student for knowledge and judgment, and observing a patient encounter with the student were identified. Higher duty days had a significant negative correlation with sharing knowledge/skills and encouraging student initiative. Higher work RVUs and total patient encounters were negatively correlated with timely feedback and constructive criticism. The results suggest that

  7. The Rise of Hospitalists: An Opportunity for Clinical Ethics.

    Translating ethical theories into clinical practice presents a perennial challenge to educators. While many suggestions have been put forth to bridge the theory-practice gap, none have sufficiently remedied the problem. We believe the ascendance of hospital medicine, as a dominant new force in medical education and patient care, presents a unique opportunity that could redefine the way clinical ethics is taught. The field of hospital medicine in the United States is comprised of more than 50,000 hospitalists-specialists in inpatient medicine-representing the fastest growing subspecialty in the history of medicine, and its members have emerged as a dominant new force around which medical education and patient care pivot. This evolution in medical education presents a unique opportunity for the clinical ethics community. Through their proximity to patients and trainees, hospitalists have the potential to teach medical ethics in real time on the wards, but most hospitalists have not received formal training in clinical ethics. We believe it is time to strengthen the ties between hospital medicine and medical ethics, and in this article we outline how clinical ethicists might collaborate with hospitalists to identify routine issues that do not rise to the level of an "ethics consult," but nonetheless require an intellectual grounding in normative reasoning. We use a clinical vignette to explore how this approach might enhance and broaden the scope of medical education that occurs in the inpatient setting: A patient with an intra-abdominal abscess is admitted to the academic hospitalist teaching service for drainage of the fluid, hemodynamic support, and antimicrobial therapy. During the initial encounter with the hospitalist and his team of medical students and residents, the patient reports night sweats and asks if this symptom could be due to the abscess. How should the hospitalist approach this question? Copyright 2017 The Journal of Clinical Ethics. All rights

    To determine the range and frequency of experiences, clinical and nonclinical roles, training, work expectations, and career plans of practicing pediatric hospitalists. Mail survey study of a national sample of 530 pediatric hospitalists of whom 67% (N = 338) were from teaching hospitals, 71% (N = 374) were from children's hospitals, 43% (N = 230) were from freestanding children's hospitals, and 69% (N = 354) were from hospitals with >or=250 beds. The response rate was 84%. The majority (54%; N = 211) had been practicing as hospitalists for at least 3 years. Most reported that the pediatric inpatient unit (94%) and inpatient consultation service (51%) were a part of their regular clinical assignment. Most did not provide service in the normal newborn nursery (58%), subspecialty inpatient service (52%), transports (85%), outpatient clinics (66%), or as part of an emergency response team (53%). Many participated in quality improvement (QI) initiatives (84%) and practice guideline development (81%). This study provides the most comprehensive information available regarding the clinical and nonclinical roles, training, work expectations, and career plans of pediatric hospitalists. However, the field is currently a moving target; there is significant flux in the hospitalist workforce and variation in the roles of these professionals in their clinical and nonclinical work environment.

    Hospitalists work in 90% of US hospitals with over 200 beds. With over 48,000 practicing hospitalists nationwide, the field of hospital medicine has grown rapidly in its 20 years of existence. Obstetrics and gynecology (OBGYN) hospitalists are uncovering similar drivers for their growth. Obstetricians cannot be in both the hospital and the office at the same time, they face an increased acuity of hospitalized patients demanding a full time presence, and hospitals are searching for physicians aligned with their goals. OBGYN hospitalists are at a similar point today at which hospital medicine was in the late 1990s. Copyright © 2015 Elsevier Inc. All rights reserved.

  13. A Hybrid Teaching and Learning Model

    Juhary, Jowati Binti

    This paper aims at analysing the needs for a specific teaching and learning model for the National Defence University of Malaysia (NDUM). The main argument is that whether there are differences between teaching and learning for academic component versus military component at the university. It is further argued that in order to achieve excellence, there should be one teaching and learning culture. Data were collected through interviews with military cadets. It is found that there are variations of teaching and learning strategies for academic courses, in comparison to a dominant teaching and learning style for military courses. Thus, in the interest of delivering quality education and training for students at the university, the paper argues that possibly a hybrid model for teaching and learning is fundamental in order to generate a one culture of academic and military excellence for the NDUM.

    Nearly two-thirds of hospitals in the United States are served by hospitalist physicians. How hospitalist work patterns and job satisfaction vary across various practice models is unknown. We administered the Hospitalist Worklife Survey to a randomized stratified sample of 3105 potential hospitalists and 662 hospitalist members of 3 multistate hospitalist companies. Details about respondents' hospitalist group characteristics, their work patterns, and satisfaction with 2 global and 11 domain measures were assessed. Factors influencing job satisfaction were also solicited. These factors, job characteristics, job satisfaction, and burnout were compared across predefined practice models. The adjusted response rate was 25.6%. Among the respondents, 44% were employed by a hospital, 15% by a multispecialty physician group, 14% by a multistate hospitalist group, 14% by a university or medical school, 12% by a local hospitalist group, and 2% by other. Hospitalists of local groups reported more clinical shifts per month, and hospitalists of local and multistate groups reported more billable encounters per shift compared to other practice models. Academic hospitalists reported fewer night shifts, fewer billable encounters per shift, more nonclinical work hours, and lower earnings compared to other practice models. Differences in clinical and nonclinical responsibilities, and differences in factors most important to job satisfaction, were noted across the 5 models. Despite these differences, levels of global job satisfaction and burnout were similar across the practice models. Work patterns, compensation, and hospitalists' priorities varied significantly across practice models. Overall job satisfaction and burnout were similar across models, despite these differences.

    Background: In 2008, the Department of Hospital Medicine at Ochsner Clinic Foundation in New Orleans, LA, began training its own students for the first time as a result of the partnership between our institution and the University of Queensland (UQ) in Brisbane, Australia, that established a global medical school. The Department of Hospital Medicine is responsible for the Medicine clerkship for third-year medical students. We have 5 resident teams at the main hospital in the system, but the majority of our hospitalists work alone. Because of staffing issues, we have had to change our mentality from having teaching hospitalists and nonteaching hospitalists to viewing all hospitalists as potential educators. Methods: The department has slowly increased the number of students in the Medicine clerkship each year with the goal of training 120 third-year students in the New Orleans area in 2016. The students in the Medicine clerkship will be divided into five 8-week rotations, allowing for 25 students to be trained at one time. Results: The UQ curriculum is similar to that of most 4-year American schools, but some differences in methods, such as a heavy emphasis on bedside instruction and oral summative assessments, are novel to us. These differences have provided our department with new goals for professional and instructor development. For the actual instruction, we pair students one on one with hospitalists and also assign them to resident teams. Student placement has been a challenge, but we are making improvements as we gain experience and explore opportunities for placement at our community hospitals. Conclusion: Our arrangement may be adapted to other institutions in the future as the number of students increases and the availability of resident teachers becomes more difficult nationwide.

    To characterize determinants of career satisfaction among pediatric hospitalists working in diverse practice settings; to develop a framework to conceptualize factors influencing career satisfaction. Semistructured interviews were conducted with community and tertiary care hospitalists, using purposeful sampling to attain maximum response diversity. We used closed- and open-ended questions to assess levels of career satisfaction and its determinants. Interviews were conducted by telephone, recorded, and transcribed verbatim. Emergent themes were identified and analyzed using an inductive approach to qualitative analysis. A total of 30 interviews were conducted with community and tertiary care hospitalists, representing 20 hospital medicine programs and 7 Northeastern states. Qualitative analysis yielded 657 excerpts, which were coded and categorized into 4 domains and associated determinants of career satisfaction: 1) professional responsibilities; 2) hospital medicine program administration; 3) hospital and health care systems; and 4) career development. Although community and tertiary care hospitalists reported similar levels of career satisfaction, they expressed variation in perspectives across these 4 domains. Although the role of hospital medicine program administration was consistently emphasized by all hospitalists, community hospitalists prioritized resource availability, work schedule, and clinical responsibilities, while tertiary care hospitalists prioritized diversity in nonclinical responsibilities and career development. We illustrate how hospitalists in different organizational settings prioritize both consistent and unique determinants of career satisfaction. Given associations between physician satisfaction and health care quality, efforts to optimize modifiable factors within this framework, at both community and tertiary care hospitals, may have broad impacts.

    The number of hospitalists in the US is growing rapidly, yet little is known about their worklife to inform whether hospital medicine is a viable long-term career for physicians. Determine current satisfaction levels among hospitalists. Survey study. A national random stratified sample of 3,105 potential hospitalists plus 662 hospitalist employees of three multi-state hospitalist companies were administered the Hospital Medicine Physician Worklife Survey. Using 5-point Likert scales, the survey assessed demographic information, global job and specialty satisfaction, and 11 satisfaction domains: workload, compensation, care quality, organizational fairness, autonomy, personal time, organizational climate, and relationships with colleagues, staff, patients, and leader. Relationships between global satisfaction and satisfaction domains, and burnout symptoms and career longevity were explored. There were 816 hospitalist responses (adjusted response rate, 25.6%). Correcting for oversampling of pediatricians, 33.5% of respondents were women, and 7.4% were pediatricians. Overall, 62.6% of respondents reported high satisfaction (≥4 on a 5-point scale) with their job, and 69.0% with their specialty. Hospitalists were most satisfied with the quality of care they provided and relationships with staff and colleagues. They were least satisfied with organizational climate, autonomy, compensation, and availability of personal time. In adjusted analysis, satisfaction with organizational climate, quality of care provided, organizational fairness, personal time, relationship with leader, compensation, and relationship with patients predicted job satisfaction. Satisfaction with personal time, care quality, patient relationships, staff relationships, and compensation predicted specialty satisfaction. Job burnout symptoms were reported by 29.9% of respondents who were more likely to leave and reduce work effort. Hospitalists rate their job and specialty satisfaction highly, but

    Surgical comanagement is an increasingly common practice in pediatric hospital medicine. Information about the structure and financing of such care is limited. The aim of the researchers for this study was to investigate pediatric hospitalist surgical comanagement models and to assess pediatric hospitalist familiarity with and patterns of billing for surgical patients. We conducted a cross-sectional cohort web-based survey of pediatric hospitalists using the American Academy of Pediatrics' Section on Hospital Medicine listserv. In our study ( N = 133), we found wide variation in our cohort in surgical patient practice management, including program structure, individual billing practices, and knowledge regarding billing practices. Even for pediatric hospitalists with comanagement service agreements between surgeons and pediatric hospitalists, there was no increased awareness or knowledge about reimbursement or billing for surgical patients. This global lack of knowledge in our small but diverse sample suggests that billing resources and training for pediatric hospitalists practicing comanagement of surgical patients are needed.

    A perception exists that residents are more costly than midlevel providers (MLPs). Since graduate medical education (GME) funding is a key issue for teaching programs, hospitals should conduct cost-benefit analyses when considering staffing models. Our aim was to compare direct patient care costs and length of stay (LOS) between resident and MLP inpatient teams. We queried the University HealthSystems Consortium clinical database (UHC CDB) for 13 553 "inpatient" discharges at our institution from July 2010 to June 2013. Patient assignment was based on bed availability rather than "educational value." Using the UHC CDB data, discharges for resident and MLP inpatient teams were compared for observed and expected LOS, direct cost derived from hospital charges, relative expected mortality (REM), and readmissions. We also compared patient satisfaction for physician domain questions using Press Ganey data. Bivariate analysis was performed for factors associated with differences between the 2 services using χ(2) analysis and Student t test for categorical and continuous variables, respectively. During the 3-year period, while REM was higher on the hospitalist-resident services (P higher for resident teams. There were no differences in patient demographics, daily discharge rates, readmissions, or deaths. Resident teams are economically more efficient than MLP teams and have higher patient satisfaction. The findings offer guidance when considering GME costs and inpatient staffing models.

    Clinical breast examination (CBE) is traditionally taught to third-year medical students using a lecture and a tabletop breast model. The opportunity to clinically practice CBE depends on patient availability and willingness to be examined by students, especially in culturally sensitive environments. We propose the use of a hybrid simulation model consisting of a standardized patient (SP) wearing a silicone breast simulator jacket and hypothesize that this, compared to traditional teaching methods, would result in improved learning. Consenting third-year medical students (N = 82) at a university-affiliated tertiary care center were cluster-randomized into two groups: hybrid simulation (breast jacket + SP) and control (tabletop breast model). Students received the standard lecture by instructors blinded to the randomization, followed by randomization group-based learning and practice sessions. Two weeks later, participants were assessed in an Objective Structured Clinical Examination (OSCE), which included three stations with SPs blinded to the intervention. The SPs graded the students on CBE completeness, and students completed a self-assessment of their performance and confidence during the examination. CBE completeness scores did not differ between the two groups (p = 0.889). Hybrid simulation improved lesion identification grades (p simulation relieved the fear of missing a lesion on CBE (p = 0.043) and increased satisfaction with the teaching method among students (p = 0.002). As a novel educational tool, hybrid simulation improves the sensitivity of CBE performed by medical students without affecting its specificity. Hybrid simulation may play a role in increasing the confidence of medical students during CBE.

This design process was grounded in the political and social context of the contested East River waterfront of New York City and valued both intensive study (using a range of social science and design methods and a partnership with a local community organization, engaging with the politics, issues and human needs of a complex site. The paper considers how we encouraged interdisciplinary collaboration and dialogue between teachers as well as between liberal arts and design students and developed strategies to overcome preconceived notions of traditional “studio” and “seminar” work. By exploring the challenges and adjustments made during the semester and the process of teaching this class, this paper addresses how we moved from a model of intertwining theory, research and practice, to a hybrid model of multiple ways of doing, a model particularly apt for teaching public space. Through examples developed for and during our course, the paper suggests practical ways of supporting this transdisciplinary hybrid model.

    Since their introduction for melanoma treatment, the use of immune checkpoint inhibitors (ICIs) has rapidly expanded. Though their impact on survival is irrefutable, these medications have been associated with autoimmune-like adverse events related to their ability to induce the immune system. One of the most commonly affected organ systems is the gastrointestinal (GI) tract, in which manifestations range from mild diarrhea to severe colitis with intestinal perforation. Because of the increased use of ICIs, hospitalists are caring for an increasing number of patients experiencing their adverse events. We present a case-oriented review of the GI adverse events associated with the use of ICIs to familiarize the hospitalist with their mechanism of action and potential complications and to emphasize the importance of early diagnosis and treatment to decrease morbidity and mortality. © 2018 Society of Hospital Medicine.

They work with several health care professionals to provide patient care. There has been little research examining the perceived impact of the hospitalist's role on staff working in an orthopedic environment. This study examined the experiences of staff across several professional backgrounds in working with a hospitalist in an orthopedic environment.Participants and methods: A qualitative descriptive approach was taken to investigate the experience of staff working with a hospitalist at a specialized orthopedic hospital. Purposive sampling was used to recruit interview participants including nurses, internists, pharmacists, physiotherapists, anesthetists, senior administration, and orthopedic surgeons to the point of theoretical saturation, which occurred after 12 interviews. Interviews were coded, and these codes were combined into categories and predominant themes were identified.Findings: Overall, staff believed that the hospitalist role was a positive addition to the facility. The role benefitted patients and supported the clinical well-being and education of staff. Many staff felt the hospitalist had no impact on their workload, but others reported that their work had decreased or increased. Several described the potential for role overlap between the hospitalist and other physicians.Conclusion: The importance of interprofessional collaboration in the implementation of the hospitalist role was a recurring theme in our analysis.

    Many studies assess provider-patient communication through text messaging; however, minimal research has addressed communication among physicians. The purpose of this study was to evaluate the use of text messaging by pediatric hospitalists. A brief, anonymous, electronic survey was distributed through the American Academy of Pediatrics Section on Hospital Medicine Listserv in February 2012. Survey questions assessed work-related text messaging. Of the 106 pediatric hospitalist respondents, 97 met inclusion criteria. Most were female (73%) and had been in practice text messages, some (12%) more than 10 times per shift. More than half (53%) received work-related text messages when not at work. When asked to identify all potential work recipients, most often sent work-related text messages to other pediatric hospitalists (64%), fellows or resident physicians (37%), and subspecialists/consulting physicians (28%). When asked their preferred mode for brief communication, respondents' preferences varied. Many (46%) respondents worried privacy laws can be violated by sending/receiving text messages, and some (30%) reported having received protected health information (PHI) through text messages. However, only 11% reported their institution offered encryption software for text messaging. Physicians were using text messaging as a means of brief, work-related communication. Concerns arose regarding transfer of PHI using unsecure systems and work-life balance. Future research should examine accuracy and effectiveness of text message communication in the hospital, as well as patient privacy issues.

    Inpatient service handoffs are a vulnerable transition during a patients' hospitalization. We hypothesized that performing the service handoff at the patients' bedside may be one mechanism to more efficiently transfer patient information between physicians, while further integrating the patient into their hospital care. We performed a 6-month prospective study of performing a bedside handoff (BHO) at the service transition on a non-teaching hospitalist service. On a weekly basis, transitioning hospitalists co-rounded at patient's bedsides. Post-handoff surveys assessed for completeness of handoff, communication, missed information, and adverse events. A control group who performed the handoff via email, phone or face-to-face was also surveyed. Chi-square and item-response theory (IRT) analysis assessed for differences between BHO and control groups. Narrative responses were elicited to qualitatively describe the BHO. In total, 21/31 (67%) scheduled BHOs were performed. On average, 4 out of 6 eligible patients experienced a BHO, with a total of 90 patients experiencing a BHO. Of those asked to perform the BHO, 52% stated the service transition took 31-60 min compared to 24% in the control group. Controlling for the nesting of observations within physicians, IRT analysis found that BHO respondents had statistically significant greater odds of: reporting increased patient awareness of the service handoff, more certainty in the plan for each patient, less discovery of missed information, and less time needed to learn about the patient on the first day compared to control methods. Narrative responses described a more patient-centered handoff with improved communication that was time-consuming and often logistically difficult to implement. Despite its time-intensive nature, performing the service handoff at the patient's bedside may lead to a more complete and efficient service transition. Published by Elsevier Inc.

    The increasing fragmentation of healthcare has resulted in more patient handoffs. Many professional groups, including the Accreditation Council on Graduate Medical Education and the Society of Hospital Medicine, have made recommendations for safe and effective handoffs. Despite the two-way nature of handoff communication, the focus of these efforts has largely been on the person giving information. To observe and characterise the listening behaviours of handoff receivers during hospitalist handoffs. Prospective observational study of shift change and service change handoffs on a non-teaching hospitalist service at a single academic tertiary care institution. The 'HEAR Checklist', a novel tool created based on review of effective listening behaviours, was used by third party observers to characterise active and passive listening behaviours and interruptions during handoffs. In 48 handoffs (25 shift change, 23 service change), active listening behaviours (eg, read-back (17%), note-taking (23%) and reading own copy of the written signout (27%)) occurred less frequently than passive listening behaviours (eg, affirmatory statements (56%) nodding (50%) and eye contact (58%)) (pRead-back occurred only eight times (17%). In 11 handoffs (23%) receivers took notes. Almost all (98%) handoffs were interrupted at least once, most often by side conversations, pagers going off, or clinicians arriving. Handoffs with more patients, such as service change, were associated with more interruptions (r=0.46, plistening behaviours. While passive listening behaviours are common, active listening behaviours that promote memory retention are rare. Handoffs are often interrupted, most commonly by side conversations. Future handoff improvement efforts should focus on augmenting listening and minimising interruptions.

    Hollier, John M; Wilson, Stephen D

    This study examines whether implementing a resident shift work schedule (RSWS) alone or combined with a hospitalist-led model system (HMS/RSWS) affects patient care outcomes or costs at a pediatric tertiary care teaching hospital. A retrospective sample compared pre- and postintervention groups for the most common primary discharge diagnoses, including asthma and cellulitis (RSWS intervention) and inflammatory bowel disease and diabetic ketoacidosis (HMS/RSWS intervention). Outcome variables included length of stay, number of subspecialty consultations, and hospitalization charges. For the RSWS intervention, the preintervention (n = 107) and postintervention (n = 92) groups showed no difference in any of the outcome variables. For the HMS/RSWS intervention, the preintervention (n = 98) and postintervention (n = 69) groups did not differ in demographics or length of stay. However, subspecialty consultations increased significantly during postintervention from 0.83 to 1.52 consults/hospitalization ( P care outcomes at a pediatric tertiary care teaching hospital.

    Person-job fit is an organizational construct shown to impact the entry, performance, and retention of workers. Even as a growing number of physicians work under employed situations, little is known about how physicians select, develop, and perform in organizational settings. Our objective was to validate in the hospitalist physician workforce features of person-job fit observed in workers of other industries. The design was a secondary survey data analysis from a national stratified sample of practicing US hospitalists. The measures were person-job fit; likelihood of leaving practice or reducing workload; organizational climate; relationships with colleagues, staff, and patients; participation in suboptimal patient care activities. Responses to the Hospital Medicine Physician Worklife Survey by 816 (sample response rate 26%) practicing hospitalists were analyzed. Job attrition and reselection improved job fit among hospitalists entering the job market. Better job fit was achieved through hospitalists engaging a variety of personal skills and abilities in their jobs. Job fit increased with time together with socialization and internalization of organizational values. Hospitalists with higher job fit felt they performed better in their jobs. Features of person-job fit for hospitalists conformed to what have been observed in nonphysician workforces. Person-job fit may be a useful complementary survey measure related to job satisfaction but with a greater focus on function. Copyright © 2012 Society of Hospital Medicine.

    Reducing 30-day readmissions is a national priority. Although multipronged programs have been shown to reduce readmissions, the role of the individual hospitalist physician in reducing readmissions is not clear. We evaluated the effect of physicians' self-review of their own readmission cases on the 30-day readmission rate. Over a 1-year period, hospitalists were sent their individual readmission rates and cases on a weekly basis. They reviewed their cases and completed a data abstraction tool. In addition, a facilitator led small group discussion about common causes of readmission and ways to prevent such readmissions. Our preintervention readmission rate was 16.16% and postintervention was 14.99% (P = .76). Among hospitalists on duty, nearly all participated in scheduled facilitated discussions. Self-review was completed in 67% of the cases. A facilitated reflective practice intervention increased hospitalist participation and awareness in the mission to reduce readmissions and this intervention resulted in a nonsignificant trend in readmission reduction.

    The pediatric hospital medicine (PHM) core competencies were established in 2010 to identify the specific knowledge base and skill set needed to provide the highest quality of care for hospitalized children. The objectives of this study were to examine the perceived core competency achievements of fellowship-trained and non-fellowship-trained early career pediatric hospitalists and identify perceived gaps in our current training models. An anonymous Web-based survey was distributed in November 2013. Hospitalists within 5 years of their residency graduation reported their perceived competency in select PHM core competencies. χ(2) and multiprobit regression analyses were utilized. One hundred ninety-seven hospitalists completed the survey and were included; 147 were non-fellowship-trained and 50 were PHM fellowship graduates or current PHM fellows. Both groups reported feeling less than competent in sedation and aspects of business practice. Non-fellowship-trained hospitalists also reported mean scores in the less than competent range in intravenous access/phlebotomy, technology-dependent emergencies, performing Plan-Do-Study-Act process and root cause analysis, defining basic statistical terms, and identifying research resources. Non-fellowship-trained hospitalists reported mean competency scores greater than fellowship-trained hospitalists in pain management, newborn care, and transitions in care. Early career pediatric hospitalists report deficits in several of the PHM core competencies, which should be considered when designing PHM-specific training in the future. Fellowship-trained hospitalists report higher levels of perceived competency in many core areas. © 2015 Society of Hospital Medicine.

    Full Text Available For approximately twenty-years, Web-enhanced learning environments have been popular in higher education. Much research has examined how best practices can integrate technology, pedagogical theories, and resources to enhance learning. Numerous studies of hybrid teaching have revealed mostly positive effects. Yet, very little research has examined how to teach a successful physical activity course using a hybrid format. Review of the literature: We reviewed the research regarding the design and implementation of a Web-enhanced physical activity course in a college population using pedagogical principles of learning and the10 self-determination theory. Method: Data were collected from students at the beginning and end of the course. The hybrid course consisted of completing weekly online activities, and selecting and participating in a face-to-face physical activity based on student’s choice. Conclusion: The authors propose this template as a model to assist faculty in designing and implementing a blended physical activity course.

    Academic hospitalist physicians face significant challenges that may threaten their chances for successful and timely promotions, such as heavy clinical workloads, limited training in research, and relatively few experienced mentors in their field. The appreciable growth of hospital medicine groups in recent years, as has occurred at our institution, compounds the predicament by diluting the limited resources that are available to support these physicians. A needs assessment was followed by the development of specific objectives for the division and for individual members of the division related to academic success. The resulting 3-pronged strategy to support the academic success of our group was based on securing strong mentorship, investing requisite resources, and committing to recruit fellowship-trained new faculty. To date, the initiative has resulted in an increased number of peer-reviewed publication and grants, as well as national leadership roles for division members.

    Bridging Geosciences to the future generations in interesting and interactive ways are challenging for lecturers and teachers. In the past, one-way 'classic' face-to-face teaching method has been used as the only alternative for undergraduate's Marine Geology class in Padjadjaran University, Indonesia. Currently, internet users in Indonesia have been increased significantly, among of them are young generations and students. The advantage of the internet as a teaching method in Geosciences topic in Indonesia is still limited. Here we have combined between the classic and the online method for undergraduate teaching. The case study was in Marine Geology class, Padjadjaran University, with 70 students as participants and 2 instructors. We used Edmodo platform as a primary tool in our teaching and Dropbox as cloud storage. All online teaching activities such as assignment, quiz, discussion and examination were done in concert with the classic one with proportion 60% and 40% respectively. We found that the students had the different experience in this hybrid teaching method as shown in their feedback through this platform. This hybrid method offers interactive ways not only between the lecturers and the students but also among students. Classroom meeting is still needed to expose their work and for general discussion.Nevertheless, the only problem was the lack of internet access in the campus when all our students accessing the platform at the same time.

    Medical Imaging is a key training component in Biomedical Engineering programs. Medical imaging education is interdisciplinary training, involving physics, mathematics, chemistry, electrical engineering, computer engineering, and applications in biology and medicine. Seeking an efficient teaching method for instructors and an effective learning environment for students has long been a goal for medical imaging education. By the support of NSF grants, we developed the medical imaging teaching software (MITS) and associated dynamic assessment tracking system (DATS). The MITS/DATS system has been applied to junior and senior medical imaging classes through a hybrid teaching model. The results show that student's learning gain improved, particularly in concept understanding and simulation project completion. The results also indicate disparities in subjective perception between junior and senior classes. Three institutions are collaborating to expand the courseware system and plan to apply it to different class settings.

    Sickle cell disease (SCD) is a chronic disease characterized by multiple vaso-occlusive complications and is increasingly cared for by hospitalists. The purpose of this study is to examine differences in pain management between hematologists and hospitalists. We performed a single-institution, retrospective review of pain management patterns and outcomes in adult SCD patients hospitalized for vaso-occlusive crisis. Over 26 months, we found a total of 298 patients (120 cared for by the hematologists and 178 by hospitalists), with a mean age of 32 (range 19-58). Patients cared for by hospitalists had a lower total number of hours on a patient controlled analgesia (PCA) device (171 vs. 212 hours, P=0.11). Hospitalists also were significantly more likely to utilize demand only PCA (42% vs. 23%, P=0.002) and had a significantly lower rate of using both continuous and demand PCA (54% vs. 67%, P=0.04). In addition, patients cared for by hospitalists had a significantly shorter hospitalization (8.4 days) compared to hematologists (10 days, P=0.04) with a non-significant difference in 7 and 30 day readmission rates (7.2% vs. 6.7% and 40% vs. 35% respectively). We found patients cared for by hospitalists more frequently utilized home oral pain medication during admission, had shorter lengths of hospitalization, and did not have a significant increase in readmission rates.

    Historically, antimicrobial stewardship programs have been led by infectious-disease physicians and pharmacists. With the growing presence of hospitalists in health and hospital systems, combined with their focus on quality improvement and patient safety, this emerging medical specialty has the potential to fill essential roles in antimicrobial stewardship programs. The goal of this article was to present the reasons hospitalists are ideally positioned to fill antimicrobial-stewardship roles, a narrative review of previously reported hospitalist-led antibiotic-stewardship projects, and a description of an ongoing multisite collaborative by the Institute for Healthcare Improvement (IHI) and the Centers for Disease Control and Prevention (CDC). A review of the published literature was performed, including an extensive review of the abstracts submitted to the Society of Hospital Medicine annual meetings. A number of examples of hospitalists developing and leading antimicrobial-stewardship programs are described. The details of a current multisite IHI/CDC hospitalist-focused initiative are discussed in detail. Hospitalists are actively involved with, and even lead, a variety of antimicrobial-stewardship programs in several different hospital systems. A large, multisite collaborative focused on hospitalist-led antimicrobial stewardship is currently in progress. Copyright © 2013 Elsevier HS Journals, Inc. All rights reserved.

In the transition period from the College of Graphics to «Integrated Graphic Technology Studies» to the contemporary Faculty of Graphics Arts with the University in Zagreb, three main periods of development can be noted: digital printing, computer prepress and automatic procedures in postpress packaging production. Computer technology has enabled a change in the methodology of teaching graphics technology and studying it on the level of secondary and higher education. The task has been set to create tools for simulating printing processes in order to master the program through a hybrid system consisting of methods that are separate in relation to one another: learning with the help of digital models and checking in the actual real system. We are setting a hybrid project for teaching because the overall acquired knowledge is the result of completely different methods. The first method is on the free programs level functioning without consequences. Everything remains as a record in the knowledge database that can be analyzed, statistically processed and repeated with new parameter values of the system being researched. The second method uses the actual real system where the results are in proving the value of new knowledge and this is something that encourages and stimulates new cycles of hybrid behavior in mastering programs. This is the area where individual learning incurs. The hybrid method allows the possibility of studying actual situations on a computer model, proving it on an actual real model and entering the area of learning envisaging future development.

    Students are exposed to basic life support (BLS) and advanced cardiac life support (ACLS) training in the first semester in some medical colleges. The aim of this study was to compare students' satisfaction between lecture-based traditional method and hybrid problem-based learning (PBL) in BLS/ACLS teaching to undergraduate medical students. We conducted a questionnaire-based, cross-sectional survey among 118 1 st -year medical students from a university medical college in the city of New Delhi, India. We aimed to assess the students' satisfaction between lecture-based and hybrid-PBL method in BLS/ACLS teaching. Likert 5-point scale was used to assess students' satisfaction levels between the two teaching methods. Data were collected and scores regarding the students' satisfaction levels between these two teaching methods were analysed using a two-sided paired t -test. Most students preferred hybrid-PBL format over traditional lecture-based method in the following four aspects; learning and understanding, interest and motivation, training of personal abilities and being confident and satisfied with the teaching method ( P < 0.05). Implementation of hybrid-PBL format along with the lecture-based method in BLS/ACLS teaching provided high satisfaction among undergraduate medical students.

    Osteoporosis is a major public health concern affecting an estimated 10 million people in the United States. To the best of our knowledge, no qualitative study has explored barriers perceived by medicine hospitalists to secondary prevention of osteoporotic hip fractures. We aimed to describe these perceived barriers and recommendations regarding how to optimize secondary prevention of osteoporotic hip fracture. In-depth, semistructured interviews were performed with 15 internal medicine hospitalists in a tertiary-care referral medical center. The interviews were analyzed with directed content analysis. Internal medicine hospitalists consider secondary osteoporotic hip fracture prevention as the responsibility of outpatient physicians. Identified barriers were stratified based on themes including physicians' perception, patients' characteristics, risks and benefits of osteoporosis treatment, healthcare delivery system, and patient care transition from the inpatient to the outpatient setting. Some of the recommendations include building an integrated system that involves a multidisciplinary team such as the fracture liaison service, initiating a change to the hospital policy to facilitate inpatient care and management of osteoporosis, and creating a smooth patient care transition to the outpatient setting. Our study highlighted how internal medicine hospitalists perceive their role in the secondary prevention of osteoporotic hip fractures and what they perceive as barriers to initiating preventive measures in the hospital. Inconsistency in patient care transition and the fragmented nature of the existing healthcare system were identified as major barriers. A fracture liaison service could remove some of these barriers.

The 39-item survey assessed frequency of concerns about serious illness communication, confidence for common tasks, and barriers using Likert-type scales. It was developed by the authors based on prior work, a focus group, and feedback from pilot respondents. We received 332 completed surveys. On most or every shift, many participants reported having concerns about a patient's or family's understanding of prognosis (53%) or the patient's code status (63%). Most participants were either confident or very confident in discussing goals of care (93%) and prognosis (87%). Fewer were confident or very confident in responding to patients or families who had not accepted the seriousness of an illness (59%) or in managing conflict (50%). Other frequently cited barriers were lack of time, lack of prior discussions in the outpatient setting, unrealistic prognostic expectations from other physicians, limited institutional support, and difficulty finding records of previous discussions. Our results suggest opportunities to improve hospitalists' ability to lead serious illness communication by increasing the time hospitalists have for discussions, improving documentation systems and communication between inpatient and outpatient clinicians, and targeted training on challenging communication scenarios.

    Primary care providers (PCPs) and hospitalists endorse the importance of effective communication yet studies illustrate critical communication problems between these 2 provider types. Our objective was to develop deeper insight into the dimensions of and underlying reasons for communication issues and determine ways to improve communication and remove barriers by eliciting the perspectives of pediatric PCPs and hospitalists. Using qualitative methods, 2 sets of focus groups were held: 1) mix of local PCPs serving diverse populations, and 2) hospitalists from a free-standing, pediatric institution. The open-ended, semistructured question guides included questions about communication experiences, patient care responsibilities, and suggestions for improvement. Using inductive thematic analysis, investigators coded the transcripts, and resolved differences through consensus. Six PCP (n = 27) and 3 hospitalist (n = 15) focus groups were held. Fifty-six percent of PCPs and 14% of hospitalists had been practicing for >10 years. Five major themes were identified: problematic aspects of communication, perceptions of provider roles, push-pull, postdischarge responsibilities/care, and proposed solutions. Aspects of communication included specific problem areas with verbal and written communication. Perceptions of provider roles highlighted the issue of PCPs feeling devalued. Push-pull described conflicting expectations about a counterpart's role and responsibilities. Postdischarge responsibilities/care addressed unclear responsibilities related to patient follow-up. Proposed solutions were suggested for ways to improve communication. Deficiencies in communication hinder successful collaboration and can cause tension between providers in inpatient and outpatient settings. Understanding specific issues that contribute to poor communication like perceptions about provider roles is critical to improving relationships and facilitating combined efforts to improve patient care

    Effective collaboration and teamwork is essential in providing safe and effective care. Research reveals deficiencies in teamwork on medical units involving hospitalists. The aim of this study was to assess the impact of an intervention, Structured Inter-Disciplinary Rounds (SIDR), on nurses' ratings of collaboration and teamwork. The study was a controlled trial involving an intervention and control hospitalist unit. The intervention, SIDR, combined a structured format for communication with a forum for regular interdisciplinary meetings. We asked nurses to rate the quality of communication and collaboration with hospitalists using a 5-point ordinal scale. We also assessed teamwork and safety climate using a validated instrument. Multivariable regression analyses were used to assess the impact on length of stay (LOS) and cost using both a concurrent and historic control. A total of 49 of 58 (84%) nurses completed surveys. A larger percentage of nurses rated the quality of communication and collaboration with hospitalists as high or very high on the intervention unit compared to the control unit (80% vs. 54%; P = 0.05). Nurses also rated the teamwork and safety climate significantly higher on the intervention unit (P = 0.008 and P = 0.03 for teamwork and safety climate, respectively). Multivariable analyses demonstrated no difference in the adjusted LOS and an inconsistent effect on cost. SIDR had a positive effect on nurses' ratings of collaboration and teamwork on a hospitalist unit, yet no impact on LOS and cost. Further study is required to assess the impact of SIDR on patient safety measures. Copyright © 2010 Society of Hospital Medicine.

    This study examined mechanisms of efficiency in a managed care hospitalist system on length of stay and total costs for common pediatric conditions. We conducted a retrospective cohort study (October 1993 to July 1998) of patients in a not-for-profit staff model (HMO 1) and a non-staff-model (HMO 2) managed care organization at a freestanding children's hospital. HMO 1 introduced a hospitalist system for patients in October 1996. Patients were included if they had 1 of 3 common diagnoses: asthma, dehydration, or viral illness. Linear regression models examining length-of-stay-specific costs for prehospitalist and posthospitalist systems were built. Distribution of length of stay for each diagnosis before and after the system change in both study groups was calculated. Interrupted time series analysis tested whether changes in the trends of length of stay and total costs occurred after implementation of the hospitalist system by HMO1 (HMO 2 as comparison group) for all 3 diagnoses combined. A total of 1970 patients with 1 of the 3 study conditions were cared for in HMO 1, and 1001 in HMO 2. After the hospitalist system was introduced in HMO 1, length of stay was reduced by 0.23 days (13%) for asthma and 0.19 days (11%) for dehydration; there was no difference for patients with viral illness. The largest relative reduction in length of stay occurred in patients with a shorter length of stay whose hospitalizations were reduced from 2 days to 1 day. This shift resulted in an average cost-per-case reduction of $105.51 (9.3%) for patients with asthma and $86.22 (7.8%) for patients with dehydration. During the same period, length of stay and total cost rose in HMO 2. Introduction of a hospitalist system in one health maintenance organization resulted in earlier discharges and reduced costs for children with asthma and dehydration compared with another one, with the largest reductions occurring in reducing some 2-day hospitalizations to 1 day. These findings suggest that

    Full Text Available The primary purpose of Brigham Young University (BYU is to provide students with a combination of sacred and secular education often described as the "BYU experience". Achieving this purpose is challenged by the rapid growth in Church membership and an enrollment cap of 30,000 students. To address these challenges, BYU sponsors the use of technology to bridge the gap between the increased Church membership and the number of students allowed under the enrollment caps. This institutional case study shows how these challenges have influenced the hybridization of teaching and learning for on campus (resident and off campus (distance students. It also describes how BYU has brought distance education to campus, and is beginning to bring campus-based educational practices to distance education.

    Full Text Available Bird Mating Optimizer (BMO is a novel meta-heuristic optimization algorithm inspired by intelligent mating behavior of birds. However, it is still insufficient in convergence of speed and quality of solution. To overcome these drawbacks, this paper proposes a hybrid algorithm (TLBMO, which is established by combining the advantages of Teaching-learning-based optimization (TLBO and Bird Mating Optimizer (BMO. The performance of TLBMO is evaluated on 23 benchmark functions, and compared with seven state-of-the-art approaches, namely BMO, TLBO, Artificial Bee Bolony (ABC, Particle Swarm Optimization (PSO, Fast Evolution Programming (FEP, Differential Evolution (DE, Group Search Optimization (GSO. Experimental results indicate that the proposed method performs better than other existing algorithms for global numerical optimization.

    OBJECTIVE Inappropriate treatment of asymptomatic bacteriuria (ASB) in the hospital setting is common. We sought to evaluate the treatment rate of ASB at the 3 hospitals and assess the impact of a hospitalist-focused improvement intervention. DESIGN Prospective, interventional trial. SETTING Two community hospitals and a tertiary-care academic center. PATIENTS Adult patients with a positive urine culture admitted to hospitalist services were included in this study. Exclusions included pregnancy, intensive care unit admission, history of a major urinary procedure, and actively being treated for a urinary tract infection (UTI) at the time of admission or >48 hours prior to urine collection. INTERVENTIONS An educational intervention using a pocket card was implemented at all sites followed by a pharmacist-based intervention at the academic center. Medical records of the first 50 eligible patients at each site were reviewed at baseline and after each intervention for signs and symptoms of UTI, microbiological results, antimicrobials used, and duration of treatment for positive urine cultures. Diagnosis of ASB was determined through adjudication by 2 hospitalists and 2 infectious diseases physicians. RESULTS Treatment rates of ASB decreased (23.5%; P=.001) after the educational intervention. Reductions in treatment rates for ASB differed by site and were greatest in patients without classic signs and symptoms of UTI (34.1%; Ppharmacist-based intervention was most effective at reducing ASB treatment rates in catheterized patients. CONCLUSIONS A hospitalist-focused educational intervention significantly reduced ASB treatment rates. The impact varied across sites and by patient characteristics, suggesting that a tailored approach may be useful. Infect Control Hosp Epidemiol 2016;37:1044-1051.

    General internists suffer higher rates of burnout and lower satisfaction with work-life balance than most specialties, but the impact of inpatient vs outpatient practice location is unclear. Physicians in the American Medical Association Physician Masterfile were previously surveyed about burnout, depression, suicidal ideation, quality of life, fatigue, work-life balance, career plans, and health behaviors. We extracted and compared data for these variables for the 130 internal medicine hospitalists and 448 outpatient general internists who participated. Analyses were adjusted for age, sex, hours worked, and practice setting. There were 52.3% of the hospitalists and 54.5% of the outpatient internists affected by burnout (P = 0.86). High scores on the emotional exhaustion subscale (43.8% vs 48.1%, P = 0.71) and on the depersonalization subscale (42.3% vs 32.7%, P = 0.17) were common but similar in frequency in the 2 groups. Hospitalists were more likely to score low on the personal accomplishment subscale (20.3% vs 9.6%, P = 0.04). There were no differences in symptoms of depression (40.3% for hospitalists vs 40.0% for outpatient internists, P = 0.73) or recent suicidality (9.2% vs 5.8%, P = 0.15). Rates of reported recent work-home conflict were similar (48.4% vs 41.3%, P = 0.64), but hospitalists were more likely to agree that their work schedule leaves enough time for their personal life and family (50.0% vs 42.0%, P = 0.007). Burnout was common among both hospitalists and outpatient general internists, although hospitalists were more satisfied with work-life balance. A better understanding of the causes of distress and identification of solutions for all internists is needed. © 2014 Society of Hospital Medicine.

    To characterize how the use of behavioral contracts may serve to focus individuals' intentions to grow as leaders. Between 2007 and 2008, participants of the Society of Hospital Medicine Leadership Academy courses completed behavioral contracts to identify 4 action plans they wanted to implement based on things learned at the Academy. Contracts were independently coded by 2 investigators and compared for agreement. Content analysis identified several major themes that relate to professional growth as leaders. Follow-up surveys assessed fulfillment of personal goals. The majority of respondents were male (84; 70.0%), and most were hospitalist leaders (76; 63.3%). Their median time practicing as hospitalists was 4 years, 14 (11.7%) were Assistant Professors, and 80 (66.7%) were in private practice. Eight themes emerged from the behavioral contracts, revealing ways in which participants wished to develop: improving communication and interpersonal relations; refining vision and goals for strategic planning; developing intrapersonal leadership; enhancing negotiation skills; committing to organizational change; understanding business drivers; establishing better metrics to assess performance; and strengthening interdepartmental relationships. At follow-up, all but 1 participant had achieved at least 1 of their personal goals. Understanding the areas that hospitalist leaders identify as "learning edges" may inform the personal learning plans of those hoping to take on leadership roles in hospital medicine.

    The study team sought to improve hospitalist communication with primary care providers (PCPs) at discharge through interventions consisting of (a) audit and feedback and (b) inclusion of a discharge communication measure in the incentive compensation for pediatric hospitalists. The setting was a 16-physician pediatric hospitalist group within a tertiary pediatric hospital. Discharge summaries were selected randomly for documentation of communication with PCPs. At baseline, 57% of charts had documented communication with PCPs, increasing to 84% during the audit and feedback period. Following the addition of a financial incentive, documentation of communication with PCPs increased to 93% and was sustained during the combined intervention period. The number of physicians meeting the study's performance goal increased from 1 to 14 by the end of the study period. A financial incentive coupled with an audit and feedback tool was effective at modifying physician behavior, achieving focused, measurable quality improvement gains. © 2014 by the American College of Medical Quality.

    Understanding the concept of career success is critical for hospital medicine groups seeking to create sustainably rewarding faculty positions. Conceptual models of career success describe both extrinsic (compensation and advancement) and intrinsic (career satisfaction and job satisfaction) domains. How hospitalists define career success for themselves is not well understood. In this study, we qualitatively explore perspectives on how early-career clinician-educators define career success. We developed a semistructured interview tool of open-ended questions validated by using cognitive interviewing. Transcribed interviews were conducted with 17 early-career academic hospitalists from 3 medical centers to thematic saturation. A mixed deductiveinductive, qualitative, analytic approach was used to code and map themes to the theoretical framework. The single most dominant theme participants described was "excitement about daily work," which mapped to the job satisfaction organizing theme. Participants frequently expressed the importance of "being respected and recognized" and "dissemination of work," which were within the career satisfaction organizing theme. The extrinsic organizing themes of advancement and compensation were described as less important contributors to an individual's sense of career success. Ambivalence toward the "academic value of clinical work," "scholarship," and especially "promotion" represented unexpected themes. The future of academic hospital medicine is predicated upon faculty finding career success. Clinician-educator hospitalists view some traditional markers of career advancement as relevant to success. However, early-career faculty question the importance of some traditional external markers to their personal definitions of success. This work suggests that the selfconcept of career success is complex and may not be captured by traditional academic metrics and milestones. © 2018 Society of Hospital Medicine

    Diabetic foot infections (DFIs) are common and represent the leading cause for hospitalization among diabetic complications. Without proper management, DFIs may lead to amputation, which is associated with a decreased quality of life and increased mortality. However, there is currently significant variation in the management of DFIs, and many providers fail to perform critical prevention and assessment measures. In this review, we will provide an overview of the diagnosis, management, and discharge planning of hospitalized patients with DFIs to guide hospitalists in the optimal inpatient care of patients with this condition. © 2017 Society of Hospital Medicine.

    Full Text Available Abstract Background Studies in General Internal Medicine [GIM] settings have shown that optimizing interprofessional communication is important, yet complex and challenging. While the physician is integral to interprofessional work in GIM there are often communication barriers in place that impact perceptions and experiences with the quality and quantity of their communication with other team members. This study aims to understand how team members’ perceptions and experiences with the communication styles and strategies of either hospitalist or consultant physicians in their units influence the quality and effectiveness of interprofessional relations and work. Methods A multiple case study methodology was used. Thirty-one semi-structured interviews were conducted with physicians, nurses and other health care providers [e.g. physiotherapist, social worker, etc.] working across 5 interprofessional GIM programs. Questions explored participants’ experiences with communication with all other health care providers in their units, probing for barriers and enablers to effective interprofessional work, as well as the use of communication tools or strategies. Observations in GIM wards were also conducted. Results Three main themes emerged from the data: [1] availability for interprofessional communication, [2] relationship-building for effective communication, and [3] physician vs. team-based approaches. Findings suggest a significant contrast in participants’ experiences with the quantity and quality of interprofessional relationships and work when comparing the communication styles and strategies of hospitalist and consultant physicians. Hospitalist staffed GIM units were believed to have more frequent and higher caliber interprofessional communication and collaboration, resulting in more positive experiences among all health care providers in a given unit. Conclusions This study helps to improve our understanding of the collaborative environment

    Hospital medicine is a relatively new specialty field, dedicated to the delivery of comprehensive medical care to hospitalized patients. YouTube is one of the most frequently used websites, offering access to a gamut of videos from self-produced to professionally made. The aim of our study was to determine the adequacy of YouTube as an effective means to define and depict the role of hospitalists. YouTube was searched on November 17, 2014, using the following search words: "hospitalist," "hospitalist definition," "what is the role of a hospitalist," "define hospitalist," and "who is a hospitalist." Videos found only in the first 10 pages of each search were included. Non-English, noneducational, and nonrelevant videos were excluded. A novel 7-point scoring tool was created by the authors based on the definition of a hospitalist adopted by the Society of Hospital Medicine. Three independent reviewers evaluated, scored, and classified the videos into high, intermediate, and low quality based on the average score. A total of 102 videos out of 855 were identified as relevant and included in the analysis. Videos uploaded by academic institutions had the highest mean score. Only 6 videos were classified as high quality, 53 as intermediate quality, and 42 as low quality, with 82.4% (84/102) of the videos scoring an average of 4 or less. Most videos found in the search of a hospitalist definition are inadequate. Leading medical organizations and academic institutions should consider producing and uploading quality videos to YouTube to help patients and their families better understand the roles and definition of the hospitalist. ©Tamer Hudali, Muralidhar Papireddy, Mukul Bhattarai, Alan Deckard, Susan Hingle.

    Hospital readmissions are considered by the Centers for Medicare and Medicaid as a metric for quality of health care delivery. Robust data on the readmission profile of patients with cancer are currently insufficient to determine whether this measure is applicable to cancer hospitals as well. To address this knowledge gap, we estimated the unplanned readmission rate and identified factors influencing unplanned readmissions in a hospitalist service at a comprehensive cancer center. We retrospectively analyzed unplanned 30-day readmission of patients discharged from the General Internal Medicine Hospitalist Service at a comprehensive cancer center between April 1, 2012, and September 30, 2012. Multiple independent variables were studied using univariable and multivariable logistic regression models, with generalized estimating equations to identify risk factors associated with readmissions. We observed a readmission rate of 22.6% in our cohort. The median time to unplanned readmission was 10 days. Unplanned readmission was more likely in patients with metastatic cancer and those with three or more comorbidities. Patients discharged to hospice were less likely to be readmitted (all P values quality measures in cancer hospitals. Copyright © 2015 by American Society of Clinical Oncology.

    Important barriers to health information exchange (HIE) adoption are clinical workflow disruptions and troubles with the system interface. Prior research suggests that HIE interfaces providing faster access to useful information may stimulate use and reduce barriers for adoption; however, little is known about informational needs of hospitalists. To study the association between patient health problems and the type of information requested from outside healthcare providers by hospitalists of a tertiary care hospital. We searched operational data associated with fax-based exchange of patient information (previous HIE implementation) between hospitalists of an internal medicine department in a large urban tertiary care hospital in Florida, and any other affiliated and unaffiliated healthcare provider. All hospitalizations from October 2011 to March 2014 were included in the search. Strong association rules between health problems and types of information requested during each hospitalization were discovered using Apriori algorithm, which were then validated by a team of hospitalists of the same department. Only 13.7% (2 089 out of 15 230) of the hospitalizations generated at least one request of patient information to other providers. The transactional data showed 20 strong association rules between specific health problems and types of information exist. Among the 20 rules, for example, abdominal pain, chest pain, and anaemia patients are highly likely to have medical records and outside imaging results requested. Other health conditions, prone to have records requested, were lower urinary tract infection and back pain patients. The presented list of strong co-occurrence of health problems and types of information requested by hospitalists from outside healthcare providers not only informs the implementation and design of HIE, but also helps to target future research on the impact of having access to outside information for specific patient cohorts.

    Among the challenges leaders in dental and allied dental education have faced in recent years is a shortage of well-qualified faculty members, especially in some specialty areas of dentistry. One proposed solution has been the use of technology. At the University of Missouri-Kansas City School of Dentistry, the departure of a faculty member who taught the highly specialized content in oral histology and embryology provided the opportunity to implement distance delivery of that course. The course is taught once a year to a combined group of dental and dental hygiene students. Previous to spring semester of 2009, the course was taught using traditional face-to-face, in-class lectures and multiple-choice examinations. During the spring semesters of 2009, 2010, and 2011, the course was taught using synchronous and asynchronous distance delivery technology. Outcomes for these courses (including course grades and performance on the National Board Dental Examination Part I) were compared to those from the 2006, 2007, and 2008 courses. Students participating in the online hybrid course were also given an author-designed survey, and the perceptions of the faculty member who made the transition from teaching the course in a traditional face-to-face format to teaching in an online hybrid format were solicited. Overall, student and faculty perceptions and student outcomes and course reviews have been positive. The results of this study can provide guidance to those seeking to use technology as one method of curricular delivery.

    Academic hospitalist groups (AHGs) are often expected to excel in multiple domains: quality improvement, patient safety, education, research, administration, and clinical care. To be successful, AHGs must develop strategies to balance their energies, resources, and performance. The balanced scorecard (BSC) is a strategic management system that enables organizations to translate their mission and vision into specific objectives and metrics across multiple domains. To date, no hospitalist group has reported on BSC implementation. We set out to develop a BSC as part of a strategic planning initiative. Based on a needs assessment of the University of California, San Francisco, Division of Hospital Medicine, mission and vision statements were developed. We engaged representative faculty to develop strategic objectives and determine performance metrics across 4 BSC perspectives. There were 41 metrics identified, and 16 were chosen for the initial BSC. It allowed us to achieve several goals: 1) present a broad view of performance, 2) create transparency and accountability, 3) communicate goals and engage faculty, and 4) ensure we use data to guide strategic decisions. Several lessons were learned, including the need to build faculty consensus, establish metrics with reliable measureable data, and the power of the BSC to drive goals across the division. We successfully developed and implemented a BSC in an AHG as part of a strategic planning initiative. The BSC has been instrumental in allowing us to achieve balanced success in multiple domains. Academic groups should consider employing the BSC as it allows for a data-driven strategic planning and assessment process. Copyright © 2013 Society of Hospital Medicine.

    Teamwork is a vital skill for health care professionals, but the fragmented systems within which they work frequently do not recognize or support good teamwork. The American Board of Internal Medicine has developed and is testing the Teamwork Effectiveness Assessment Module (TEAM), a tool for physicians to evaluate how they perform as part of an interprofessional patient care team. The assessment provides hospitalist physicians with feedback data drawn from their own work of caring for patients, in a way that is intended to support immediate, concrete change efforts to improve the quality of patient care. Our approach demonstrates the value of looking at teamwork in the real world of health care-that is, as it occurs in the actual contexts in which providers work together to care for patients. The assessment of individual physicians' teamwork competencies may play a role in the larger effort to bring disparate health professions together in a system that supports and rewards a team approach in hope of improving patient care.

    Improving early discharges may improve patient flow and increase hospital capacity. We conducted a national survey of academic medical centers addressing the prevalence, importance, and effectiveness of early-discharge initiatives. We assembled a list of hospitalist and general internal medicine leaders at 115 US-based academic medical centers. We emailed each institutional representative a 30-item online survey regarding early-discharge initiatives. The survey included questions on discharge prioritization, the prevalence and effectiveness of early-discharge initiatives, and barriers to implementation. We received 61 responses from 115 institutions (53% response rate). Forty-seven (77%) "strongly agreed" or "agreed" that early discharge was a priority. "Discharge by noon" was the most cited goal (n = 23; 38%) followed by "no set time but overall goal for improvement" (n = 13; 21%). The majority of respondents reported early discharge as more important than obtaining translators for non-English-speaking patients and equally important as reducing 30-day readmissions and improving patient satisfaction. The most commonly reported factors delaying discharge were availability of postacute care beds (n = 48; 79%) and patient-related transport complications (n = 44; 72%). The most effective early discharge initiatives reported involved changes to the rounding process, such as preemptive identification and early preparation of discharge paperwork (n = 34; 56%) and communication with patients about anticipated discharge (n = 29; 48%). There is a strong interest in increasing early discharges in an effort to improve hospital throughput and patient flow. © 2017 Society of Hospital Medicine.

    Complete documentation of patient comorbidities in the medical record is important for clinical care, hospital reimbursement, and quality performance measures. We designed a pocket card reminder and brief educational intervention aimed at hospitalists with the goal of improving documentation of 6 common comorbidities present on admission: coagulation abnormalities, metastatic cancer, anemia, fluid and electrolyte abnormalities, malnutrition, and obesity. Two internal medicine inpatient teams led by 10 hospitalist physicians at an academic medical center received the educational intervention and pocket card reminder (n = 520 admissions). Two internal medicine teams led by nonhospitalist physicians served as a control group (n = 590 admissions). Levels of documentation of 6 common comorbidities, expected length of stay, and expected mortality were measured at baseline and during the 9-month study period. The intervention was associated with increased documentation of anemia, fluid and electrolyte abnormalities, malnutrition, and obesity in the intervention group, both compared to baseline and compared to the control group during the study period. The expected length of stay increased in the intervention group during the study period. A simple educational intervention and pocket card reminder were associated with improved documentation and hospital quality measures at an academic medical center.

    The purpose of this qualitative study was to characterize the adequacy, effectiveness, and barriers related to research mentorship among junior pediatric hospitalists and general pediatricians at a large academic institution. Junior faculty and staff physicians in hospital medicine and general pediatrics at a large academic institution were invited to participate in this qualitative study. In-depth interviews were conducted. Experienced mentors were invited to be interviewed for theoretical sampling. Interviews were conducted and analyzed by using grounded theory methodology. Twenty-six (75%) of the eligible physicians, pediatric hospitalists representing 65% of this sample, agreed to be interviewed about their mentoring experiences. Satisfied and dissatisfied participants expressed similar mentoring themes: acquisition of research skills, academic productivity, and career development. Four experienced mentors were interviewed and provided rationale for mentoring clinicians in research. Both groups of participants agreed that institutional support is vital for promoting mentorship. Junior pediatric hospitalists and general pediatricians indicated considerable interest in being mentored to learn to do clinical research. Developing faculty and staff physicians to their utmost potential is critical for advancement in academic medicine. Mentoring clinical physicians seeking to add research skills and academic productivity to their practice merits study as an innovative path to develop clinical investigators. Hospital medicine, as a rapidly developing pediatric specialty, is well-positioned to implement the necessary infrastructure to mentor junior faculty in their academic pursuits, thereby optimizing the potential impact for individuals, families, learners, and institutions.

    Borofsky, Jennifer S; Bartsch, Jason C; Howard, Alan B; Repp, Allen B

    Communication practices around interhospital transfer have not been rigorously assessed in adult medicine patients. Furthermore, the clinical implications of such practices have not been reported. This case-control study was designed to assess the quality of communication between clinicians during interhospital transfer and to determine if posttransfer adverse events (PTAEs) are associated with suboptimal communication. Cases included patients transferred to a Medicine Hospitalist Service from an outside hospital who subsequently experienced a PTAE, defined as unplanned transfer to an intensive care unit or death within 24 hours of transfer. Control patients also underwent interhospital transfer but did not experience a PTAE. A blinded investigator retrospectively reviewed the recorded pretransfer phone conversations between sending and receiving clinicians for adherence to a set of 13 empiric best practice communication elements. The primary outcome was the mean communication score, on a scale of 0-13. Mean scores between PTAE (8.3; 95% confidence interval [CI], 7.6-8.9) and control groups (7.9; 95% CI, 7.1-8.8) did not differ significantly (p = .50), although suboptimal communication on a subset of these elements was associated with increased PTAEs. Communication around interhospital transfer appears suboptimal compared with an empiric set of standard communication elements. Posttransfer adverse events were not associated with aggregate adherence to these standards.

  2. Necessity is the mother of invention: an innovative hospitalist-resident initiative for improving quality and reducing readmissions from skilled nursing facilities.

    Science.gov (United States)

    Petigara, Sunny; Krishnamurthy, Mahesh; Livert, David

    2017-03-01

    Background : Hospital readmissions have been a major challenge to the US health system. Medicare data shows that approximately 25% of Medicare skilled nursing facility (SNF) residents are readmitted back to the hospital within 30 days. Some of the major reasons for high readmission rates include fragmented information exchange during transitions of care and limited access to physicians round-the-clock in SNFs. These represent safety, quality, and health outcome concerns. Aim : The goal of the project was to reduce hospital readmission rates from SNFs by improving transition of care and increasing physician availability in SNFs (five to seven days a week physical presence with 24/7 accessibility by phone). Methods : We proposed a model whereby a hospitalist-led team, including the resident on the geriatrics rotation, followed patients discharged from the hospital to one SNF. Readmission rates pre- and post-implementation were compared. Study results : The period between January 2014 and June 2014 served as the baseline and showed readmission rate of 32.32% from the SNF back to the hospital. After we implemented the new hospitalist SNF model in June 2014, readmission rates decreased to 23.96% between July 2014 and December 2014. From January 2015 to June 2015, the overall readmission rate from the SNF reduced further to 16.06%. Statistical analysis revealed a post-intervention odds ratio of 0.403 (p < 0.001). Conclusion : The government is piloting several care models that incentivize value- based behavior. Our study strongly suggests that the hospitalist-resident continuity model of following patients to the SNFs can significantly decrease 30-days hospital readmission rates.

    We aim to address palliative care workforce shortages by teaching clinicians how to provide primary palliative care through peer coaching. We offered peer coaching to internal medicine residents and hospitalists (attendings, nurse practioners, and physician assistants). An audit of peer coaching encounters and coachee feedback to better understand the applicability of peer coaching in the inpatient setting to teach primary palliative care. Residents and hospitalist attendings participated in peer coaching for a broad range of palliative care-related questions about pain and symptom management (44%), communication (34%), and hospice (22%). Clinicians billed for 68% of encounters using a time-based billing model. Content analysis of coachee feedback identified that the most useful elements of coaching are easy access to expertise, tailored teaching, and being in partnership. Peer coaching can be provided in the inpatient setting to teach primary palliative care and potentially extend the palliative care work force.

  4. HSTLBO: A hybrid algorithm based on Harmony Search and Teaching-Learning-Based Optimization for complex high-dimensional optimization problems.

    Directory of Open Access Journals (Sweden)

    Shouheng Tuo

    Full Text Available Harmony Search (HS and Teaching-Learning-Based Optimization (TLBO as new swarm intelligent optimization algorithms have received much attention in recent years. Both of them have shown outstanding performance for solving NP-Hard optimization problems. However, they also suffer dramatic performance degradation for some complex high-dimensional optimization problems. Through a lot of experiments, we find that the HS and TLBO have strong complementarity each other. The HS has strong global exploration power but low convergence speed. Reversely, the TLBO has much fast convergence speed but it is easily trapped into local search. In this work, we propose a hybrid search algorithm named HSTLBO that merges the two algorithms together for synergistically solving complex optimization problems using a self-adaptive selection strategy. In the HSTLBO, both HS and TLBO are modified with the aim of balancing the global exploration and exploitation abilities, where the HS aims mainly to explore the unknown regions and the TLBO aims to rapidly exploit high-precision solutions in the known regions. Our experimental results demonstrate better performance and faster speed than five state-of-the-art HS variants and show better exploration power than five good TLBO variants with similar run time, which illustrates that our method is promising in solving complex high-dimensional optimization problems. The experiment on portfolio optimization problems also demonstrate that the HSTLBO is effective in solving complex read-world application.

    2017-01-01

    Background and aims  EUS-guided biliary drainage (EUS-BD) and rendezvous (EUS-RV) are acceptable rescue options for patients with failed endoscopic retrograde cholangiopancreatography (ERCP). However, there are limited training opportunities at most centers owing to low case volumes. The existing models do not replicate the difficulties encountered during EUS-BD. We aimed to develop and validate a model for stepwise learning of EUS-BD and EUS-RV, which replicates the actual EUS-BD procedures. Methods  A hybrid model was created utilizing pig esophagus and stomach, with a synthetic duodenum and biliary system. The model was objectively assessed on a grade of 1 – 4 by two experts. Twenty-eight trainees were given initial training with didactic lectures and live procedures. This was followed by hands-on training in EUS-BD and EUS-RV on the hybrid model. Trainees were assessed for objective criteria of technical difficulties. Results  Both the experts graded the model as very good or above for all parameters. All trainees could complete the requisite steps of EUS-BD and EUS-RV in a mean time of 11 minutes (8 – 18 minutes). Thirty-six technical difficulties were noted during the training (wrong scope position, 13; incorrect duct puncture, 12; guidewire related problems, 11). Technical difficulties peaked for EUS-RV, followed by hepaticogastrostomy (HGS) and choledochoduodenostomy (CDS) (20, 9, and 7, P  = 0.001). At 10 days follow-up, nine of 28 trainees had successfully performed three EUS-RV and seven EUS-BD procedures independently. Conclusions  The Mumbai EUS II hybrid model replicates situations encountered during EUS-RV and EUS-BD. Stepwise mentoring improves the chances of success in EUS-RV and EUS-BD procedures.

    Radical changes in role, education, and practice have affected how education of advance practice nurses and practice deliverables occur. This article examines the effects of distance education upon the teaching/learning of psychotherapy in integrating Web-based technology and platforms. With the advent and proliferation of online programs of study, the question begs: How do distance-linked programs successfully introduce, practice, and supervise one-to-one and group psychotherapy training? By employing evidence-based education strategies, technology, and strong interpersonal skills and evidence-based therapies, a charter Psychiatric Mental Health Nurse Practitioner Doctor of Nursing Practice program paved an innovative and successful path. In that program, they prepared their students for full scope of practice, upon graduation, inclusive of psychotherapy as well as the other highly demanding and compressed requirements of the 3-year program. This article explores that journey and its recommendations for application derived from this 2010 cohort. © 2017 Wiley Periodicals, Inc.

    The rationale for hybrid fusion-fission reactors is the production of fissile fuel for fission reactors. A new class of reactor, the fission-suppressed hybrid promises unusually good safety features as well as the ability to support 25 light-water reactors of the same nuclear power rating, or even more high-conversion-ratio reactors such as the heavy-water type. One 4000-MW nuclear hybrid can produce 7200 kg of 233 U per year. To obtain good economics, injector efficiency times plasma gain (eta/sub i/Q) should be greater than 2, the wall load should be greater than 1 MW.m -2 , and the hybrid should cost less than 6 times the cost of a light-water reactor. Introduction rates for the fission-suppressed hybrid are usually rapid

  3. Hybridized Tetraquarks

    Esposito, A.; Polosa, A.D.

    2016-01-01

    We propose a new interpretation of the neutral and charged X, Z exotic hadron resonances. Hybridized-tetraquarks are neither purely compact tetraquark states nor bound or loosely bound molecules. The latter would require a negative or zero binding energy whose counterpart in h-tetraquarks is a positive quantity. The formation mechanism of this new class of hadrons is inspired by that of Feshbach metastable states in atomic physics. The recent claim of an exotic resonance in the Bs pi+- channel by the D0 collaboration and the negative result presented subsequently by the LHCb collaboration are understood in this scheme, together with a considerable portion of available data on X, Z particles. Considerations on a state with the same quantum numbers as the X(5568) are also made.

    Hybrid securities do not constitute a new phenomenon in the Swedish capital markets. Most commonly, hybrids issued by Swedish real estate companies in recent years are preference shares. Corporate hybrid bonds on the other hand may be considered as somewhat of a new-born child in the family of hybrid instruments. These do, as all other hybrid securities, share some equity-like and some debt-like characteristics. Nevertheless, since 2013 the interest for the instrument has grown rapidly and ha...

    Full text: In the last 10 years significant innovations of EDXRF, e.g. total reflection XRF or polarized beam XRF, were utilized in different industrial applications. The decrease of background within the spectra was the goal of these developments. Excellent detection limits and sensitivities demonstrate the success of these new techniques. Nevertheless, further improvements are possible by using Si drift detectors. These detectors allow the processing of input count rates up to 10 6 cps in comparison to 10 5 of Si(Li) detectors. New excitation optics are necessary to produce such count rates. One possibility is the use of doubly curved crystals between tube and sample. These crystals enable the reflection of the primary beam within the given solid angle (0.4π) of an end window tube to the sample. Using such brightness optics excellent sensitivities mainly for light elements are achievable. The combination of a BRAGG crystal as a wavelength dispersive component and a solid state detector as an energy dispersive component creates a new technique: hybrid XRF.

    F1 hybrids can outperform their parents in yield and vegetative biomass, features of hybrid vigor that form the basis of the hybrid seed industry. The yield advantage of the F1 is lost in the F2 and subsequent generations. In Arabidopsis, from F2 plants that have a F1-like phenotype, we have by recurrent selection produced pure breeding F5/F6 lines, hybrid mimics, in which the characteristics of the F1 hybrid are stabilized. These hybrid mimic lines, like the F1 hybrid, have larger leaves than the parent plant, and the leaves have increased photosynthetic cell numbers, and in some lines, increased size of cells, suggesting an increased supply of photosynthate. A comparison of the differentially expressed genes in the F1 hybrid with those of eight hybrid mimic lines identified metabolic pathways altered in both; these pathways include down-regulation of defense response pathways and altered abiotic response pathways. F6 hybrid mimic lines are mostly homozygous at each locus in the genome and yet retain the large F1-like phenotype. Many alleles in the F6 plants, when they are homozygous, have expression levels different to the level in the parent. We consider this altered expression to be a consequence of transregulation of genes from one parent by genes from the other parent. Transregulation could also arise from epigenetic modifications in the F1. The pure breeding hybrid mimics have been valuable in probing the mechanisms of hybrid vigor and may also prove to be useful hybrid vigor equivalents in agriculture. PMID:26283378

  8. Marine Fish Hybridization

    Natural hybridization is reproduction (without artificial influence) between two or more species/populations which are distinguishable from each other by heritable characters. Natural hybridizations among marine fishes were highly underappreciated due to limited research effort; it seems that this phenomenon occurs more often than is commonly recognized. As hybridization plays an important role in biodiversity processes in the marine environment, detecting hybridization events and investigating hybridization is important to understand and protect biodiversity. The first chapter sets the framework for this disseration study. The Cohesion Species Concept was selected as the working definition of a species for this study as it can handle marine fish hybridization events. The concept does not require restrictive species boundaries. A general history and background of natural hybridization in marine fishes is reviewed during in chapter as well. Four marine fish hybridization cases were examed and documented in Chapters 2 to 5. In each case study, at least one diagnostic nuclear marker, screened from among ~14 candidate markers, was found to discriminate the putative hybridizing parent species. To further investigate genetic evidence to support the hybrid status for each hybrid offspring in each case, haploweb analysis on diagnostic markers (nuclear and/or mitochondrial) and the DAPC/PCA analysis on microsatellite data were used. By combining the genetic evidences, morphological traits, and ecological observations together, the potential reasons that triggered each hybridization events and the potential genetic/ecology effects could be discussed. In the last chapter, sequences from 82 pairs of hybridizing parents species (for which COI barcoding sequences were available either on GenBank or in our lab) were collected. By comparing the COI fragment p-distance between each hybridizing parent species, some general questions about marine fish hybridization were discussed: Is

Henkin’s techniques are so important in hybrid logic. We do so by proving a completeness result for a hybrid type theory called HTT, probably the strongest hybrid logic that has yet been explored. Our completeness result builds on earlier work with a system called BHTT, or basic hybrid type theory...... is due to the first-order perspective, which lies at the heart of Henin’s best known work and hybrid logic....

    This paper provided details of a hybrid taxi pilot program conducted to compare the on-road performance of Toyota Camry hybrid vehicles against conventional vehicles over a 1-year period in order to determine the business case and air emission reductions associated with the use of hybrid taxi cabs. Over 750,000 km worth of fuel consumption was captured from 10 Toyota Camry hybrids, a Toyota Prius, and 5 non-hybrid Camry vehicles over an 18-month period. The average real world fuel consumption for the taxis demonstrated that the Toyota Prius has the lowest cost of ownership, while the non-hybrid Camry has the highest cost of ownership. Carbon dioxide (CO{sub 2}) reductions associated with the 10 Camry hybrid taxis were calculated at 236 tonnes over a 7-year taxi service life. Results suggested that the conversion of Toronto's 5680 taxis would yield annual CO{sub 2} emission reductions of over 19,000 tonnes. All hybrid purchasers identified themselves as highly likely to purchase a hybrid again. 5 tabs., 9 figs.

  20. Managing hybrid marketing systems.

    Moriarty, R T; Moran, U

    1990-01-01

    As competition increases and costs become critical, companies that once went to market only one way are adding new channels and using new methods - creating hybrid marketing systems. These hybrid marketing systems hold the promise of greater coverage and reduced costs. But they are also hard to manage; they inevitably raise questions of conflict and control: conflict because marketing units compete for customers; control because new indirect channels are less subject to management authority. Hard as they are to manage, however, hybrid marketing systems promise to become the dominant design, replacing the "purebred" channel strategy in all kinds of businesses. The trick to managing the hybrid is to analyze tasks and channels within and across a marketing system. A map - the hybrid grid - can help managers make sense of their hybrid system. What the chart reveals is that channels are not the basic building blocks of a marketing system; marketing tasks are. The hybrid grid forces managers to consider various combinations of channels and tasks that will optimize both cost and coverage. Managing conflict is also an important element of a successful hybrid system. Managers should first acknowledge the inevitability of conflict. Then they should move to bound it by creating guidelines that spell out which customers to serve through which methods. Finally, a marketing and sales productivity (MSP) system, consisting of a central marketing database, can act as the central nervous system of a hybrid marketing system, helping managers create customized channels and service for specific customer segments.

    Science has shown that the introgression or hybridization of modern humans (Homo sapiens) with Neanderthals up to 40,000 YBP may have led to the swarm of modern humans on earth. However, there is little doubt that modern trade and transportation in support of the humans has continued to introduce additional species, genotypes, and hybrids to every country on the globe. We assessed the utility of species distributions modeling of genotypes to assess the risk of current and future invaders. We evaluated 93 locations of the genus Tamarix for which genetic data were available. Maxent models of habitat suitability showed that the hybrid, T. ramosissima x T. chinensis, was slightly greater than the parent taxa (AUCs > 0.83). General linear models of Africanized honey bees, a hybrid cross of Tanzanian Apis mellifera scutellata and a variety of European honey bee including A. m. ligustica, showed that the Africanized bees (AUC = 0.81) may be displacing European honey bees (AUC > 0.76) over large areas of the southwestern U.S. More important, Maxent modeling of sub-populations (A1 and A26 mitotypes based on mDNA) could be accurately modeled (AUC > 0.9), and they responded differently to environmental drivers. This suggests that rapid evolutionary change may be underway in the Africanized bees, allowing the bees to spread into new areas and extending their total range. Protecting native species and ecosystems may benefit from risk maps of harmful invasive species, hybrids, and genotypes.

    Hospital medicine is a rapidly growing field of internal medicine. However, little is known about internal medicine residents' decisions to pursue careers in hospital medicine (HM). To identify which internal medicine residents choose a career in HM, and describe changes in this career choice over the course of their residency education. Observational cohort using data collected from the annual Internal Medicine In-Training Examination (IM-ITE) survey. 16,781 postgraduate year 3 (PGY-3) North American internal medicine residents who completed the annual IM-ITE survey in 2009-2011, 9,501 of whom completed the survey in all 3 years of residency. Self-reported career plans for individual residents during their postgraduate year 1 (PGY-1), postgraduate year 2 (PGY-2) and PGY-3. Of the 16,781 graduating PGY-3 residents, 1,552 (9.3 %) reported HM as their ultimate career choice. Of the 951 PGY-3 residents planning a HM career among the 9,501 residents responding in all 3 years, 128 (13.5 %) originally made this decision in PGY-1, 192 (20.2 %) in PGY-2, and 631 (66.4 %) in PGY-3. Only 87 (9.1 %) of these 951 residents maintained a career decision of HM during all three years of residency education. Hospital medicine is a reported career choice for an important proportion of graduating internal medicine residents. However, the majority of residents do not finalize this decision until their final year.

    Full Text Available This article is targeted to faculty teaching race and ethnicity, racism, diversity, and multicultural courses. Many students equate race with skin color. The premise of this article is that to teach students about the social construction of race, teachers must first know enough science to teach students that race is not biological. This article examines the biology of race by showing how advances in DNA sequencing led to genetics research that supports arguments that race is not biological. DNA comparisons show that all human populations living today are one species that came from Africa. The article explains the migration of humans out of Africa about 60,000 years ago and how they populated Australia, then Asia, Europe, and the Americas. The article shows how recent research maps the timing of the migration and admixture of specific population groups into Europe and India. The article shows how a mutation in one nucleotide can result in a trait like blue eyes, or Hemoglobin S (which confers resistance to malaria, which can be subject to evolution through natural selection. DNA comparisons show how natural selection shaped the genetics of human skin color to adapt to less UV light in the northern latitudes of Europe and Asia. The article shows that there is no relation between skin color or other “racial” characteristics and complex traits like intelligence. The science in this article will help teachers explain that as race is not biological, race is socially constructed and culturally enacted.

    Hybrid cardiac single photon emission computed tomography (SPECT)/CT imaging allows combined assessment of anatomical and functional aspects of cardiac disease. In coronary artery disease (CAD), hybrid SPECT/CT imaging allows detection of coronary artery stenosis and myocardial perfusion abnormalities. The clinical value of hybrid imaging has been documented in several subsets of patients. In selected groups of patients, hybrid imaging improves the diagnostic accuracy to detect CAD compared to the single imaging techniques. Additionally, this approach facilitates functional interrogation of coronary stenoses and guidance with regard to revascularization procedures. Moreover, the anatomical information obtained from CT coronary angiography or coronary artery calcium scores (CACS) adds prognostic information over perfusion data from SPECT. The use of cardiac hybrid imaging has been favoured by the dissemination of dedicated hybrid systems and the release of dedicated image fusion software, which allow simple patient throughput for hybrid SPECT/CT studies. Further technological improvements such as more efficient detector technology to allow for low-radiation protocols, ultra-fast image acquisition and improved low-noise image reconstruction algorithms will be instrumental to further promote hybrid SPECT/CT in research and clinical practice.

    After a definition of hybrid calculation (combination of analogue and digital calculation) with a distinction between series and parallel hybrid computing, and a description of a hybrid computer structure and of task sharing between computers, this course proposes a description of hybrid hardware used in Saclay and Cadarache computing centres, and of operations performed by these systems. The next part addresses issues related to programming languages and software. The fourth part describes how a problem is organised for its processing on these computers. Methods of hybrid analysis are then addressed: resolution of optimisation problems, of partial differential equations, and of integral equations by means of different methods (gradient, maximum principle, characteristics, functional approximation, time slicing, Monte Carlo, Neumann iteration, Fischer iteration)

    2018-02-01

    The consistency between the exchange-correlation functional used in pseudopotential construction and in the actual density functional theory calculation is essential for the accurate prediction of fundamental properties of materials. However, routine hybrid density functional calculations at present still rely on generalized gradient approximation pseudopotentials due to the lack of hybrid functional pseudopotentials. Here, we present a scheme for generating hybrid functional pseudopotentials, and we analyze the importance of pseudopotential density functional consistency for hybrid functionals. For the PBE0 hybrid functional, we benchmark our pseudopotentials for structural parameters and fundamental electronic gaps of the Gaussian-2 (G2) molecular dataset and some simple solids. Our results show that using our PBE0 pseudopotentials in PBE0 calculations improves agreement with respect to all-electron calculations.

    International Nuclear Information System (INIS)

    Semay, Claude; Buisseret, Fabien; Silvestre-Brac, Bernard

    2009-01-01

    A hybrid meson is a quark-antiquark pair in which, contrary to ordinary mesons, the gluon field is in an excited state. In the framework of constituent models, the interaction potential is assumed to be the energy of an excited string. An approximate, but accurate, analytical solution of the Schroedinger equation with such a potential is presented. When applied to hybrid charmonia and bottomonia, towers of states are predicted in which the masses are a linear function of a harmonic oscillator band number for the quark-antiquark pair. Such a formula could be a reliable guide for the experimental detection of heavy hybrid mesons.

    This work reports on models described by two real scalar fields coupled with gravity in the five-dimensional spacetime, with a warped geometry involving one infinite extra dimension. Through a mechanism that smoothly changes a thick brane into a hybrid brane, one investigates the appearance of hybrid branes hosting internal structure, characterized by the splitting on the energy density and the volcano potential, induced by the parameter which controls interactions between the two scalar fields. In particular, we investigate distinct symmetric and asymmetric hybrid brane scenarios. (orig.)

    Hybrid hybridomas are obtained by fusion of two cells, each producing its own antibody. Several authors have reported the construction of murine hybrid hybridomas with the aim to obtain bispecific monoclonal antibodies. The authors have investigated, in a model system, the feasibility of constructing a human hybrid hybridoma. They fused two monoclonal cell lines: an ouabain-sensitive and azaserine/hypoxanthine-resistant Epstein-Barr virus-transformed human cell line that produces an IgG1kappa antibody directed against tetanus toxiod and an azaserine/hypoxanthine-sensitive and ouabain-resistant human-mouse xenohybrid cell line that produces a human IgG1lambda antibody directed against hepatitis-B surface antigen. Hybrid hybridoma cells were selected in culture medium containing azaserine/hypoxanthine and ouabain. The hybrid nature of the secreted antibodies was analyzed by means of two antigen-specific immunoassay. The results show that it is possible, with the combined use of transformation and xenohybridization techniques, to construct human hybrid hybridomas that produce bispecific antibodies. Bispecific antibodies activity was measured by means of two radioimmunoassays.

  17. Systems for hybrid cars

    Science.gov (United States)

    Bitsche, Otmar; Gutmann, Guenter

    Not only sharp competition but also legislation are pushing development of hybrid drive trains. Based on conventional internal combustion engine (ICE) vehicles, these drive trains offer a wide range of benefits from reduced fuel consumption and emission to multifaceted performance improvements. Hybrid electric drive trains may also facilitate the introduction of fuel cells (FC). The battery is the key component for all hybrid drive trains, as it dominates cost and performance issues. The selection of the right battery technology for the specific automotive application is an important task with an impact on costs of development and use. Safety, power, and high cycle life are a must for all hybrid applications. The greatest pressure to reduce cost is in soft hybrids, where lead-acid embedded in a considerate management presents the cheapest solution, with a considerable improvement in performance needed. From mild to full hybridization, an improvement in specific power makes higher costs more acceptable, provided that the battery's service life is equivalent to the vehicle's lifetime. Today, this is proven for the nickel-metal hydride system. Lithium ion batteries, which make use of a multiple safety concept, and with some development anticipated, provide even better prospects in terms of performance and costs. Also, their scalability permits their application in battery electric vehicles—the basis for better performance and enhanced user acceptance. Development targets for the batteries are discussed with a focus on system aspects such as electrical and thermal management and safety.

    This chapter discusses the range of characteristics attainable from hybrid reactor blankets; blanket design considerations; hybrid reactor designs; alternative fuel hybrid reactors; multi-purpose hybrid reactors; and hybrid reactors and the energy economy. Hybrid reactors are driven by a fusion neutron source and include fertile and/or fissile material. The fusion component provides a copious source of fusion neutrons which interact with a subcritical fission component located adjacent to the plasma or pellet chamber. Fissile fuel and/or energy are the main products of hybrid reactors. Topics include high F/M blankets, the fissile (and tritium) breeding ratio, effects of composition on blanket properties, geometrical considerations, power density and first wall loading, variations of blanket properties with irradiation, thermal-hydraulic and mechanical design considerations, safety considerations, tokamak hybrid reactors, tandem-mirror hybrid reactors, inertial confinement hybrid reactors, fusion neutron sources, fissile-fuel and energy production ability, simultaneous production of combustible and fissile fuels, fusion reactors for waste transmutation and fissile breeding, nuclear pumped laser hybrid reactors, Hybrid Fuel Factories (HFFs), and scenarios for hybrid contribution.

  3. New hybrid systems

    International Nuclear Information System (INIS)

    Bernardin, B.

    2001-01-01

    New hybrid systems are made up of a subcritical core, a spallation target and a proton accelerator. The neutrons that are produced in the target by the flux of protons are necessary to maintain the chain reaction of fission. Some parameters that are important for a classical nuclear reactor like doppler coefficient or delayed neutron fraction do not matter in a hybrid system. In a PWR-type reactor or in a fast reactor the concentration of actinides has a bad impact on these 2 parameters, so it is justified to study hybrid systems as actinide transmuters. The hybrid system, because of its external source of neutrons can put aside an important reactivity margin. This reactivity margin can be used to design safer nuclear reactors (particularly in some situations of reactivity accidents) or to irradiate fuel elements containing high concentrations of minor actinides that could not be allowed in a classical reactor. This article reviews various ways of integrating hybrid systems in a population of already existing nuclear reactors in order to manage quantities of plutonium, of minor actinides or of long-life fission products.

  6. Hybrid system concepts

    International Nuclear Information System (INIS)

    Landeyro, P.A.

    1995-01-01

    Hybrid systems studied for fissile material production, were reconsidered for minor actinide and long-lived fission product destruction as alternative to the traditional final disposal of nuclear waste. Now there are attempts to extend the use of the concepts developed for minor actinide incineration to plutonium burning. The most promising hybrid system concept considers fuel and target both as liquids. From the results obtained, the possibility to adopt composite targets seems the most promising solution, but still there remains the problem of Pu production, not acceptable in a burning system. This kind of targets can be mainly used for fissile material production, while for accelerator driven burners it is most convenient to use a liquid lead target. The most suitable solvent is heavy water for minor actinide annihilation in the blanket of a hybrid system. Due to the criticality conditions and the necessity of electric energy production, the blanket using plutonium dissolved in molten salts is the most convenient one. (author)

    Hybrid nanoscale patterning strategies combine the registration and addressability of conventional lithographic techniques with the chemical and physical functionality enabled by intermolecular, electrostatic and/or biological interactions. This review aims to highlight and to provide a comprehensive description of recent developments in hybrid nanoscale patterning strategies that enhance existing lithographic techniques or can be used to fabricate functional chemical patterns that interact with their environment. These functional structures create new capabilities, such as the fabrication of physicochemical surfaces that can recognize and capture analytes from complex liquid or gaseous mixtures. The nanolithographic techniques we describe can be classified into three general areas: traditional lithography, soft lithography and scanning-probe lithography. The strengths and limitations of each hybrid patterning technique will be discussed, along with the current and potential applications of the resulting patterned, functional surfaces.

    1981-01-01

    At a time when the potential benefits of various energy options are being seriously evaluated in many countries through-out the world, it is both timely and important to evaluate the practical application of fusion reactors for their economical production of nuclear fissile fuels from fertile fuels. The fusion hybrid reactor represents a concept that could assure the availability of adequate fuel supplies for a proven nuclear technology and have the potential of being an electrical energy source as opposed to an energy consumer as are the present fuel enrichment processes. Westinghouse Fusion Power Systems Department, under Contract No. EG-77-C-02-4544 with the Department of Energy, Office of Fusion Energy, has developed a preliminary conceptual design for an early twenty-first century fusion hybrid reactor called the commercial Tokamak Hybrid Reactor (CTHR). This design was developed as a first generation commercial plant producing fissile fuel to support a significant number of client Light Water Reactor (LWR) Plants. To the depth this study has been performed, no insurmountable technical problems have been identified. The study has provided a basis for reasonable cost estimates of the hybrid plants as well as the hybrid/LWR system busbar electricity costs. This energy system can be optimized to have a net cost of busbar electricity that is equivalent to the conventional LWR plant, yet is not dependent on uranium ore prices or standard enrichment costs, since the fusion hybrid can be fueled by numerous fertile fuel resources. A nearer-term concept is also defined using a beam driven fusion driver in lieu of the longer term ignited operating mode. (orig.)

    The natural draught wet cooling tower with a height of 160 m is considerably taller than the 80 m high hybrid cooling tower, but the latter has a considerably larger diameter. Spray losses for both types are about 4.5 kg/sec for a thermal output of 2500 MW. Apart from the pump load, the natural cooling tower requires no power. Apart from higher pump loads, the hybrid cooling tower requires power for the fans. The energy demand for this purpose is 1.5 to 3% of the nett powerstation output.

  1. Nuclear hybrid energy infrastructure

    Energy Technology Data Exchange (ETDEWEB)

    Agarwal, Vivek; Tawfik, Magdy S.

    2015-02-01

    The nuclear hybrid energy concept is becoming a reality for the US energy infrastructure where combinations of the various potential energy sources (nuclear, wind, solar, biomass, and so on) are integrated in a hybrid energy system. This paper focuses on challenges facing a hybrid system with a Small Modular Reactor at its core. The core of the paper will discuss efforts required to develop supervisory control center that collects data, supports decision-making, and serves as an information hub for supervisory control center. Such a center will also be a model for integrating future technologies and controls. In addition, advanced operations research, thermal cycle analysis, energy conversion analysis, control engineering, and human factors engineering will be part of the supervisory control center. Nuclear hybrid energy infrastructure would allow operators to optimize the cost of energy production by providing appropriate means of integrating different energy sources. The data needs to be stored, processed, analyzed, trended, and projected at right time to right operator to integrate different energy sources.

  6. Hybrid quantum computation

    2011-01-01

    We present a hybrid model of the unitary-evolution-based quantum computation model and the measurement-based quantum computation model. In the hybrid model, part of a quantum circuit is simulated by unitary evolution and the rest by measurements on star graph states, thereby combining the advantages of the two standard quantum computation models. In the hybrid model, a complicated unitary gate under simulation is decomposed in terms of a sequence of single-qubit operations, the controlled-z gates, and multiqubit rotations around the z axis. Every single-qubit and the controlled-z gate are realized by a respective unitary evolution, and every multiqubit rotation is executed by a single measurement on a required star graph state. The classical information processing in our model requires only an information flow vector and propagation matrices. We provide the implementation of multicontrol gates in the hybrid model. They are very useful for implementing Grover's search algorithm, which is studied as an illustrative example.

  7. Hybrid keyword search auctions

    KAUST Repository

    Goel, Ashish; Munagala, Kamesh

    2009-01-01

    Search auctions have become a dominant source of revenue generation on the Internet. Such auctions have typically used per-click bidding and pricing. We propose the use of hybrid auctions where an advertiser can make a per-impression as well as a per-click bid, and the auctioneer then chooses one of the two as the pricing mechanism. We assume that the advertiser and the auctioneer both have separate beliefs (called priors) on the click-probability of an advertisement. We first prove that the hybrid auction is truthful, assuming that the advertisers are risk-neutral. We then show that this auction is superior to the existing per-click auction in multiple ways: 1. We show that risk-seeking advertisers will choose only a per-impression bid whereas risk-averse advertisers will choose only a per-click bid, and argue that both kind of advertisers arise naturally. Hence, the ability to bid in a hybrid fashion is important to account for the risk characteristics of the advertisers. 2. For obscure keywords, the auctioneer is unlikely to have a very sharp prior on the click-probabilities. In such situations, we show that having the extra information from the advertisers in the form of a per-impression bid can result in significantly higher revenue. 3. An advertiser who believes that its click-probability is much higher than the auctioneer's estimate can use per-impression bids to correct the auctioneer's prior without incurring any extra cost. 4. The hybrid auction can allow the advertiser and auctioneer to implement complex dynamic programming strategies to deal with the uncertainty in the click-probability using the same basic auction. The per-click and per-impression bidding schemes can only be used to implement two extreme cases of these strategies. As Internet commerce matures, we need more sophisticated pricing models to exploit all the information held by each of the participants. We believe that hybrid auctions could be an important step in this direction. The hybrid

    Hybrid nanostructures are a class of materials that are typically composed of two or more different components, in which each component has at least one dimension on the nanoscale. The rational design and controlled synthesis of hybrid nanostructures are of great importance in enabling the fine tuning of their properties and functions. Epitaxial growth is a promising approach to the controlled synthesis of hybrid nanostructures with desired structures, crystal phases, exposed facets and/or interfaces. This Review provides a critical summary of the state of the art in the field of epitaxial growth of hybrid nanostructures. We discuss the historical development, architectures and compositions, epitaxy methods, characterization techniques and advantages of epitaxial hybrid nanostructures. Finally, we provide insight into future research directions in this area, which include the epitaxial growth of hybrid nanostructures from a wider range of materials, the study of the underlying mechanism and determining the role of epitaxial growth in influencing the properties and application performance of hybrid nanostructures.

    A system model of the mirror hybrid reactor has been developed. The major components of the model include (1) the reactor description, (2) a capital cost analysis, (3) various fuel management schemes, and (4) an economic analysis that includes the hybrid plus its associated fission burner reactors. The results presented describe the optimization of the mirror hybrid reactor, the objective being to minimize the cost of electricity from the hybrid fission-burner reactor complex. We have examined hybrid reactors with two types of blankets, one containing natural uranium, the other thorium. The major difference between the two optimized reactors is that the uranium hybrid is a significant net electrical power producer, whereas the thorium hybrid just about breaks even on electrical power. Our projected costs for fissile fuel production are approximately 50 $/g for 239 Pu and approximately 125 $/g for 233 U

  10. Energy Efficiency Comparison between Hydraulic Hybrid and Hybrid Electric Vehicles

    Full Text Available Conventional vehicles tend to consume considerable amounts of fuel, which generates exhaust gases and environmental pollution during intermittent driving cycles. Therefore, prospective vehicle designs favor improved exhaust emissions and energy consumption without compromising vehicle performance. Although pure electric vehicles feature high performance and low pollution characteristics, their limitations are their short driving range and high battery costs. Hybrid electric vehicles (HEVs are comparatively environmentally friendly and energy efficient, but cost substantially more compared with conventional vehicles. Hydraulic hybrid vehicles (HHVs are mainly operated using engines, or using alternate combinations of engine and hydraulic power sources while vehicles accelerate. When the hydraulic system accumulator is depleted, the conventional engine reengages; concurrently, brake-regenerated power is recycled and reused by employing hydraulic motor–pump modules in circulation patterns to conserve fuel and recycle brake energy. This study adopted MATLAB Simulink to construct complete HHV and HEV models for backward simulations. New European Driving Cycles were used to determine the changes in fuel economy. The output of power components and the state-of-charge of energy could be retrieved. Varying power component models, energy storage component models, and series or parallel configurations were combined into seven different vehicle configurations: the conventional manual transmission vehicle, series hybrid electric vehicle, series hydraulic hybrid vehicle, parallel hybrid electric vehicle, parallel hydraulic hybrid vehicle, purely electric vehicle, and hydraulic-electric hybrid vehicle. The simulation results show that fuel consumption was 21.80% lower in the series hydraulic hybrid vehicle compared to the series hybrid electric vehicle; additionally, fuel consumption was 3.80% lower in the parallel hybrid electric vehicle compared to the

    2006-01-01

    We review the scenario of sneutrino hybrid inflation, where one of the singlet sneutrinos, the superpartners of the right-handed neutrinos, plays the role of the inflaton. In a minimal model of sneutrino hybrid inflation, the spectral index is given by ns ≅ 1 + 2γ. With γ = 0.025 ± 0.01 constrained by WMAP, a running spectral index vertical bar dns/dlnk vertical bar << vertical barγvertical bar and a tensor-to-scalar ratio r << γ2 are predicted. Small neutrino masses arise from the seesaw mechanism, with heavy masses for the singlet (s)neutrinos generated by the vacuum expectation value of the waterfall field after inflation. The baryon asymmetry of the universe can be explained by non-thermal leptogenesis via sneutrino inflaton decay, with low reheat temperature TRH ≅ 106 GeV

    Superconductors, especially high T c ones, are the most attractive materials to design stable and fully passive magnetic suspensions which have to control five degrees of freedom. The hybrid superconducting magnetic suspensions present high performances and a simple cooling mode. They consist of a permanent magnet bearing, stabilized by a suitable magnet-superconductor structure. Several designs are given and compared in terms of forces and stiffnesses. The design of the magnet bearing plays an important part. The superconducting magnetic bearing participates less in levitation but must provide a high stabilizing stiffness. This is achieved by the magnet configuration, a good material in term of critical current density and field cooling. A hybrid superconducting suspension for a flywheel is presented. This system consists of a magnet thrust bearing stabilized by superconductors interacting with an alternating polarity magnet structure. First tests and results are reported. Superconducting materials are magnetically melt-textured YBaCuO

    Programming languages always seem to do some things well but not others: Python punts when it comes to user interfaces, Java’s artificial complexity prevents rapid development and produces tangles, and it will be awhile before we see benefits from C++ concurrency work. The cognitive load of languages and their blind spots increases the cost of experimentation, impeding your ability to fail fast and iterate. If you use a single language to solve your problem, you are binding yourself to the worldview limitations and the mistakes made by the creator of that language. Consider increasing your wiggle room by crossing language boundaries, complementing a language that is powerful in one area with a different language powerful in another. Language hybridization can speed development to quickly discover your real problems, giving you more time to fix them. After making a case for hybridizing your thinking in general, I will present a number of simple examples; first showing the benefits of using other languages...

    3D properties of the hybrid undulator scheme arc studied numerically using PANDIRA code. It is shown that there exist two well defined sets of undulator parameters which provide either maximum on-axis field amplitude or minimal higher harmonics amplitude of the basic undulator field. Thus the alternative between higher field amplitude or pure sinusoidal field exists. The behavior of the undulator field amplitude and harmonics structure for a large set of (undulator gap)/(undulator wavelength) values is demonstrated.

Fission energy is running out of readily available fuel, and fusion has extra neutrons which can be used to breed that fission fuel. Fusion would have to take on an extra burden of radioactivity, but this early application would give fusion, which does not work well enough now to make power, practical experience which may accelerate development of pure fusion

    Hybrid Nanoparticles (AHNs) are rationally-designed multifunctional nanostructures and novel building blocks for the next generation of advanced materials and devices. Nanoscale materials attract considerable interest because of their unusual properties and potential for practical applications. Most of the activity in this field is focused on the synthesis of homogeneous nanoparticles from metals, metal oxides, semiconductors, and polymers. It is well recognized that properties of nanoparticles can be further enhanced if they are made as hybrid structures. This program is concerned with the synthesis, characterization, and application of such hybrid structures termed AHNs. AHNs are composed of a homogeneous core and several caps of different materials deposited on its surface (Fig. 1). Combined properties of the core and the caps as well as new properties that arise from core-cap and cap-cap interactions render AHNs multifunctional. In addition, specific chemical reactivity of the caps enables directional self-assembly of AHNs into complex architectures that are not possible with only spherical nanoparticles.

    There is a large-scale need and desire for energy in remote communities, especially in the developing world; however the lack of a user friendly, flexible performance prediction model for hybrid power systems incorporating renewables hindered the analysis of hybrids as options to conventional solutions. A user friendly model was needed with the versatility to simulate the many system locations, widely varying hardware configurations, and differing control options for potential hybrid power systems. To meet these ends, researchers from the National Renewable Energy Laboratory (NREL) and the University of Massachusetts (UMass) developed the Hybrid2 software. This paper provides an overview of the capabilities, features, and functionality of the Hybrid2 code, discusses its validation and future plans. Model availability and technical support provided to Hybrid2 users are also discussed. 12 refs., 3 figs., 4 tabs.

    2011-01-01

    Hybrid logic is an extension of modal logic which allows us to refer explicitly to points of the model in the syntax of formulas. It is easy to justify interest in hybrid logic on applied grounds, with the usefulness of the additional expressive power. For example, when reasoning about time one...... often wants to build up a series of assertions about what happens at a particular instant, and standard modal formalisms do not allow this. What is less obvious is that the route hybrid logic takes to overcome this problem often actually improves the behaviour of the underlying modal formalism....... For example, it becomes far simpler to formulate proof-systems for hybrid logic, and completeness results can be proved of a generality that is simply not available in modal logic. That is, hybridization is a systematic way of remedying a number of known deficiencies of modal logic. First-order hybrid logic...

    Using the 5-degree of freedom parallel-serial hybrid robot, to realize the de-burring, new forward and inverse kinematic calculation methods based on the 'off-line teaching' method are proposed. This hybrid robot consists of a parallel stage section and a serial stage section. Considering this point, each section is calculated individually. And the continuous path control algorithm of this hybrid robot is proposed. To verify the usefulness, a prototype robot is tested which is controlled based on the proposed methods. This verification includes a positioning test and a pose test. The positioning test evaluates the continuous path of the tool center point. The pose test evaluates the pose on the tool center point. As the result, it is confirmed that this hybrid robot moves correctly using the proposed methods

    Glueballs, hybrids and multiquark states are predicted as bound states in models guided by quantum chromo dynamics (QCD), by QCD sum rules or QCD on a lattice. Estimates for the (scalar) glueball ground state are in the mass range from 1000 to 1800 MeV, followed by a tensor and a pseudoscalar glueball at higher mass. Experiments have reported evidence for an abundance of meson resonances with 0{sup -+},0{sup ++} and 2{sup ++} quantum numbers. In particular, the sector of scalar mesons is full of surprises starting from the elusive {sigma} and {kappa} mesons. The a{sub 0}(980) and f{sub 0}(980), discussed extensively in the literature, are reviewed with emphasis on their Janus-like appearance as KK-bar molecules, tetraquark states or qq-bar mesons. Most exciting is the possibility that the three mesons f{sub 0}(1370), f{sub 0}(1500), and f{sub 0}(1710) might reflect the appearance of a scalar glueball in the world of quarkonia. However, the existence of f{sub 0}(1370) is not beyond doubt and there is evidence that both f{sub 0}(1500) and f{sub 0}(1710) are flavour octet states, possibly in a tetraquark composition. We suggest a scheme in which the scalar glueball is dissolved into the wide background into which all scalar flavour-singlet mesons collapse. There is an abundance of meson resonances with the quantum numbers of the {eta}. Three states are reported below 1.5GeV/c{sup 2} whereas quark models expect only one, perhaps two. One of these states, {iota}(1440), was the prime glueball candidate for a long time. We show that {iota}(1440) is the first radial excitation of the {eta} meson. Hybrids may have exotic quantum numbers which are not accessible by qq-bar mesons. There are several claims for J{sup PC}=1{sup -+} exotics, some of them with properties as predicted from the flux tube model interpreting the quark-antiquark binding by a gluon string. The evidence for these states depends partly on the assumption that meson-meson interactions are dominated by s

  11. Hybrid simulation using mixed reality for interventional ultrasound imaging training.

    Ultrasound (US) imaging offers advantages over other imaging modalities and has become the most widespread modality for many diagnostic and interventional procedures. However, traditional 2D US requires a long training period, especially to learn how to manipulate the probe. A hybrid interactive system based on mixed reality was designed, implemented and tested for hand-eye coordination training in diagnostic and interventional US. A hybrid simulator was developed integrating a physical US phantom and a software application with a 3D virtual scene. In this scene, a 3D model of the probe with its relative scan plane is coherently displayed with a 3D representation of the phantom internal structures. An evaluation study of the diagnostic module was performed by recruiting thirty-six novices and four experts. The performances of the hybrid (HG) versus physical (PG) simulator were compared. After the training session, each novice was required to visualize a particular target structure. The four experts completed a 5-point Likert scale questionnaire. Seventy-eight percentage of the HG novices successfully visualized the target structure, whereas only 45% of the PG reached this goal. The mean scores from the questionnaires were 5.00 for usefulness, 4.25 for ease of use, 4.75 for 3D perception, and 3.25 for phantom realism. The hybrid US training simulator provides ease of use and is effective as a hand-eye coordination teaching tool. Mixed reality can improve US probe manipulation training.

    Full Text Available Current photon counting x-ray detector (PCD technology faces limitations associated with spectral fidelity and photon starvation. One strategy for addressing these limitations is to supplement PCD data with high-resolution, low-noise data acquired with an energy-integrating detector (EID. In this work, we propose an iterative, hybrid reconstruction technique which combines the spectral properties of PCD data with the resolution and signal-to-noise characteristics of EID data. Our hybrid reconstruction technique is based on an algebraic model of data fidelity which substitutes the EID data into the data fidelity term associated with the PCD reconstruction, resulting in a joint reconstruction problem. Within the split Bregman framework, these data fidelity constraints are minimized subject to additional constraints on spectral rank and on joint intensity-gradient sparsity measured between the reconstructions of the EID and PCD data. Following a derivation of the proposed technique, we apply it to the reconstruction of a digital phantom which contains realistic concentrations of iodine, barium, and calcium encountered in small-animal micro-CT. The results of this experiment suggest reliable separation and detection of iodine at concentrations ≥ 5 mg/ml and barium at concentrations ≥ 10 mg/ml in 2-mm features for EID and PCD data reconstructed with inherent spatial resolutions of 176 μm and 254 μm, respectively (point spread function, FWHM. Furthermore, hybrid reconstruction is demonstrated to enhance spatial resolution within material decomposition results and to improve low-contrast detectability by as much as 2.6 times relative to reconstruction with PCD data only. The parameters of the simulation experiment are based on an in vivo micro-CT experiment conducted in a mouse model of soft-tissue sarcoma. Material decomposition results produced from this in vivo data demonstrate the feasibility of distinguishing two K-edge contrast agents with

    In this paper we explore the logic of now, yesterday, today and tomorrow by combining the semantic approach to indexicality pioneered by Hans Kamp [9] and refined by David Kaplan [10] with hybrid tense logic. We first introduce a special now nominal (our @now corresponds to Kamp’s original now...... operator N) and prove completeness results for both logical and contextual validity. We then add propositional constants to handle yesterday, today and tomorrow; our system correctly treats sentences like “Niels will die yesterday” as contextually unsatisfiable. Building on our completeness results for now......, we prove completeness for the richer language, again for both logical and contextual validity....

    Full Text Available Drawing from the growing literature on interdisciplinarity and my own experiences as an intellectual hybrid, I discuss the personal and institutional challenges inherent in crossing disciplinary boundaries in the academy. I argue that boundary crossing is a natural occurrence and that the issue of (interdisciplinarity is a matter of degree and of determining who gets to define the boundaries. Defining boundaries is not merely an intellectual enterprise, but also a political act that delineates what is, or is not, legitimate scholarship. This issue is especially salient to women's and gender studies during times of economic distress and educational budget cuts.

  20. The evolution of teaching.

    Teaching, alongside imitation, is widely thought to underlie the success of humanity by allowing high-fidelity transmission of information, skills, and technology between individuals, facilitating both cumulative knowledge gain and normative culture. Yet, it remains a mystery why teaching should be widespread in human societies but extremely rare in other animals. We explore the evolution of teaching using simple genetic models in which a single tutor transmits adaptive information to a related pupil at a cost. Teaching is expected to evolve where its costs are outweighed by the inclusive fitness benefits that result from the tutor's relatives being more likely to acquire the valuable information. We find that teaching is not favored where the pupil can easily acquire the information on its own, or through copying others, or for difficult to learn traits, where teachers typically do not possess the information to pass on to relatives. This leads to a narrow range of traits for which teaching would be efficacious, which helps to explain the rarity of teaching in nature, its unusual distribution, and its highly specific nature. Further models that allow for cumulative cultural knowledge gain suggest that teaching evolved in humans because cumulative culture renders otherwise difficult-to-acquire valuable information available to teach. © 2011 The Author(s).

  2. Nonminimally coupled hybrid inflation

    International Nuclear Information System (INIS)

    Koh, Seoktae; Minamitsuji, Masato

    2011-01-01

    We discuss the hybrid inflation model where the inflaton field is nonminimally coupled to gravity. In the Jordan frame, the potential contains φ 4 term as well as terms in the original hybrid inflation model. In our model, inflation can be classified into the type (I) and the type (II). In the type (I), inflation is terminated by the tachyonic instability of the waterfall field, while in the type (II) by the violation of slow-roll conditions. In our model, the reheating takes place only at the true minimum and even in the case (II) finally the tachyonic instability occurs after the termination of inflation. For a negative nonminimal coupling, inflation takes place in the vacuum-dominated region, in the large field region, or near the local minimum/maximum. Inflation in the vacuum-dominated region becomes either the type (I) or (II), resulting in a blue or red spectrum of the curvature perturbations, respectively. Inflation around the local maximum can be either the type (I) or the type (II), which results in the red spectrum of the curvature perturbations, while around the local minimum it must be the type (I), which results in the blue spectrum. In the large field region, to terminate inflation, potential in the Einstein frame must be positively tilted, always resulting in the red spectrum. We then numerically solve the equations of motion to investigate the whole dynamics of inflaton and confirm that the spectrum of curvature perturbations changes from red to blue ones as scales become smaller.

    Hybrid electric power trains may revolutionize today's ground passenger vehicles by significantly improving fuel economy and decreasing emissions. The NASA Lewis Research Center is working with industry, universities, and Government to develop and demonstrate a hybrid electric vehicle. Our partners include Bowling Green State University, the Cleveland Regional Transit Authority, Lincoln Electric Motor Division, the State of Ohio's Department of Development, and Teledyne Ryan Aeronautical. The vehicle will be a heavy class urban transit bus offering double the fuel economy of today's buses and emissions that are reduced to 1/10th of the Environmental Protection Agency's standards. At the heart of the vehicle's drive train is a natural-gas-fueled engine. Initially, a small automotive engine will be tested as a baseline. This will be followed by the introduction of an advanced gas turbine developed from an aircraft jet engine. The engine turns a high-speed generator, producing electricity. Power from both the generator and an onboard energy storage system is then provided to a variable-speed electric motor attached to the rear drive axle. An intelligent power-control system determines the most efficient operation of the engine and energy storage system.

    The role of the fusion-fission hybrid reactor (FFHR) as a fissile fuel and/or power producer is discussed. As long range options to supply the world energy needs, hybrid-fueled thermal-burner reactors are compared to liquid metal fast breeder reactors (LMFBR). A discussion of different fuel cycles (thorium, depleted uranium, and spent fuel) is presented in order to compare the energy multiplication, the production of fissile fuel, the laser efficiency and pellet gain requirements of the hybrid reactor. Lawrence Livermore Laboratory (LLL) has collaborated with Bechtel Corporation and with Westinghouse in two engineering design studies of laser fusion driven hybrid power plants. The hybrid designs which have resulted from these two studies are briefly described and analyzed by considering operational parameters, such as energy multiplication, power density, burn-up and plutonium production as a function time

    2017-12-01

    Full Text Available Learning a language means also the study of a different culture. This study focuses on the introduction of the topic of culture in language teaching into the curriculum of the subject Language Teaching Methodology for teacher trainees studying at Translation And Interpreting Studies, Sapientia Hungarian University of Transylvania, Faculty of Technical and Human Sciences, Târgu-Mureş. This topic has not been treated separately so far, it has only been discussed implicitly, included in other topics. But we believe that future teachers should have a more thorough theoretical and practical training in terms of what incorporating culture into language teaching implies. For this purpose, we are going to examine and discuss some of the recommendations and principles stated in the specialized literature regarding culture in foreign language teaching and reflect on what the ideal content of a course related to the teaching of this skill should be.

  2. Hybrid Natural Inflation

    Ross, Graham G.; Germán, Gabriel; Vázquez, J. Alberto

    2016-05-01

    We construct two simple effective field theory versions of Hybrid Natural Inflation (HNI) that illustrate the range of its phenomenological implications. The resulting inflationary sector potential, V = Δ4(1 + acos( ϕ/f)), arises naturally, with the inflaton field a pseudo-Nambu-Goldstone boson. The end of inflation is triggered by a waterfall field and the conditions for this to happen are determined. Also of interest is the fact that the slow-roll parameter ɛ (and hence the tensor r) is a non-monotonic function of the field with a maximum where observables take universal values that determines the maximum possible tensor to scalar ratio r. In one of the models the inflationary scale can be as low as the electroweak scale. We explore in detail the associated HNI phenomenology, taking account of the constraints from Black Hole production, and perform a detailed fit to the Planck 2015 temperature and polarisation data.

    A hybrid powertrain system is provided that includes a first prime mover having a rotational output, a second prime mover having a rotational output, and a transmission having a main shaft supporting at least two main shaft gears thereon. The transmission includes a first independent countershaft drivingly connected to the first prime mover and including at least one ratio gear supported thereon that meshes with a respective main shaft gear. A second independent countershaft is drivingly connected to the second prime mover and includes at least one ratio gear supported thereon that meshes with a respective main shaft gear. The ratio gears on the first and second countershafts cooperate with the main shaft gears to provide at least one gear ratio between the first and second countershafts and the main shaft. A shift control mechanism selectively engages and disengages the first and second countershafts for rotation with the main shaft.

    A method and apparatus for heating a catalytic converter's catalyst to an efficient operating temperature in a hybrid electric vehicle when the vehicle is in a charge limited mode such as e.g., the charge depleting mode or when the vehicle's high voltage battery is otherwise charge limited. The method and apparatus determine whether a high voltage battery of the vehicle is incapable of accepting a first amount of charge associated with a first procedure to warm-up the catalyst. If it is determined that the high voltage battery is incapable of accepting the first amount of charge, a second procedure with an acceptable amount of charge is performed to warm-up the catalyst.

    2018-02-01

    The controlled generation and identification of quantum correlations, usually encoded in either qubits or continuous degrees of freedom, builds the foundation of quantum information science. Recently, more sophisticated approaches, involving a combination of two distinct degrees of freedom, have been proposed to improve on the traditional strategies. Hyperentanglement describes simultaneous entanglement in more than one distinct degree of freedom, whereas hybrid entanglement refers to entanglement shared between a discrete and a continuous degree of freedom. In this work we propose a scheme that allows us to combine the two approaches, and to extend them to the strongest form of quantum correlations. Specifically, we show how two identical, initially separated particles can be manipulated to produce Bell nonlocality among their spins, among their momenta, as well as across their spins and momenta. We discuss possible experimental realizations with atomic and photonic systems.

    1997-01-01

    A government, industry, and university cooperative is developing an advanced hybrid electric city transit bus. Goals of this effort include doubling the fuel economy compared to current buses and reducing emissions to one-tenth of current EPA standards. Unique aspects of the vehicle's power system include the use of ultra-capacitors as an energy storage system, and a planned natural gas fueled turbogenerator developed from a small jet engine. Power from both the generator and energy storage system is provided to a variable speed electric motor attached to the rear axle. At over 15000 kg gross weight, this is the largest vehicle of its kind ever built using ultra-capacitor energy storage. This paper describes the overall power system architecture, the evolution of the control strategy, and its performance over industry standard drive cycles.

    The search for the electric dipole moment of the neutron requires the ambient magnetic field to be on the pT scale which is accomplished with large magnetic shielding rooms. These rooms are fitted with large mu-metal sheets to allow for passive cancellation of background magnetic fields. Active shielding technology cannot uniformly cancel background magnetic fields. These issues can be remedied by combining the methods into a hybrid system. The design used is composed of panels that have an active layer of cancellation between two sheets of mu-metal. The panels form a cube and draw in magnetic fields perpendicular to the surface which can then be reduced using active shielding. This work is supported by the Department of Energy under Contract DE-SC0008107.

    In this paper we investigate the use of action systems with differential actions in the specifcation of hybrid systems. As the main contribution we generalize the definition of a differential action, allowing the use of arbitrary relations over model variables and their time......-derivatives in modelling continuous-time dynamics. The generalized differential action has an intuitively appealing predicate transformer semantics, which we show to be both conjunctive and monotonic. In addition, we show that differential actions blend smoothly with conventional actions in action systems, even under...... parallel composition. Moreover, as the strength of the action system formalism is the support for stepwise development by refinement, we investigate refinement involving a differential action. We show that, due to the predicate transformer semantics, standard action refinement techniques apply also...

At SiO2 volume fractions, , bracketing a critical value y ≈ 0.29, the suspensions jam and their mechanical modulus increase by more than seven orders. For >y, the mean pore diameter is close to the anion size, yet the ionic conductivity remains surprisingly high and can be understood, at all , using a simple effective medium model proposed by Maxwell. SiO 2-polyethylene glycol hybrid electrolytes are also reported to manifest attractive electrochemical stability windows (0.3-6.3 V) and to reach a steady-state interfacial impedance when in contact with metallic lithium. © 2010 The Royal Society of Chemistry.

    2012-01-01

    Cabin environmental control is an important issue for a successful Moon mission. Due to the unique environment of the Moon, lunar dust control is one of the main problems that significantly diminishes the air quality inside spacecraft cabins. Therefore, this innovation was motivated by NASA s need to minimize the negative health impact that air-suspended lunar dust particles have on astronauts in spacecraft cabins. It is based on fabrication of a hybrid filter comprising nanofiber nonwoven layers coated on porous polymer membranes with uniform cylindrical pores. This design results in a high-efficiency gas particulate filter with low pressure drop and the ability to be easily regenerated to restore filtration performance. A hybrid filter was developed consisting of a porous membrane with uniform, micron-sized, cylindrical pore channels coated with a thin nanofiber layer. Compared to conventional filter media such as a high-efficiency particulate air (HEPA) filter, this filter is designed to provide high particle efficiency, low pressure drop, and the ability to be regenerated. These membranes have well-defined micron-sized pores and can be used independently as air filters with discreet particle size cut-off, or coated with nanofiber layers for filtration of ultrafine nanoscale particles. The filter consists of a thin design intended to facilitate filter regeneration by localized air pulsing. The two main features of this invention are the concept of combining a micro-engineered straight-pore membrane with nanofibers. The micro-engineered straight pore membrane can be prepared with extremely high precision. Because the resulting membrane pores are straight and not tortuous like those found in conventional filters, the pressure drop across the filter is significantly reduced. The nanofiber layer is applied as a very thin coating to enhance filtration efficiency for fine nanoscale particles. Additionally, the thin nanofiber coating is designed to promote capture of

This "Teaching & Learning Tips" series is designed to be an accessible guide for dermatologists who want to improve their teaching skills. It is comprised of 12 articles about how to enhance teaching in various settings informed by research about how people learn and expert-derived or data-driven best practices for teaching. The series begins with a review of principles to optimize learning in any setting, including cognitive load theory, active learning strategies, and the impact of motivation and emotion on learning. It transitions into a practical "how to" guide format for common teaching scenarios in dermatology, such as lecturing, case-based teaching, and teaching procedures, among others.

    We apply a recently developed analytic model for the evolution of monopole networks to the case of monopoles attached to one string, usually known as hybrid networks. We discuss scaling solutions for both local and global hybrid networks, and also find an interesting application for the case of vortons. Our quantitative results agree with previous estimates in indicating that the hybrid networks will usually annihilate soon after the string-forming phase transition. However, we also show that in some specific circumstances these networks can survive considerably more than a Hubble time.

    Network technology has become a creative tool of changing human productivity, the rapid development of it has brought profound changes to our learning, working and life. Network technology has many advantages such as rich contents, various forms, convenient retrieval, timely communication and efficient combination of resources. Network information resources have become the new education resources, get more and more application in the education, has now become the teaching and learning tools. Network teaching enriches the teaching contents, changes teaching process from the traditional knowledge explanation into the new teaching process by establishing situation, independence and cooperation in the network technology platform. The teacher's role has shifted from teaching in classroom to how to guide students to learn better. Network environment only provides a good platform for the teaching, we can get a better teaching effect only by constantly improve the teaching content. Changchun university of science and technology introduced a BB teaching platform, on the platform, the whole optical classroom teaching and the classroom teaching can be improved. Teachers make assignments online, students learn independently offline or the group learned cooperatively, this expands the time and space of teaching. Teachers use hypertext form related knowledge of applied optics, rich cases and learning resources, set up the network interactive platform, homework submission system, message board, etc. The teaching platform simulated the learning interest of students and strengthens the interaction in the teaching.

  13. Commencement Speech as a Hybrid Polydiscursive Practice

    Directory of Open Access Journals (Sweden)

    2017-12-01

    Full Text Available Discourse and media communication researchers pay attention to the fact that popular discursive and communicative practices have a tendency to hybridization and convergence. Discourse which is understood as language in use is flexible. Consequently, it turns out that one and the same text can represent several types of discourses. A vivid example of this tendency is revealed in American commencement speech / commencement address / graduation speech. A commencement speech is a speech university graduates are addressed with which in compliance with the modern trend is delivered by outstanding media personalities (politicians, athletes, actors, etc.. The objective of this study is to define the specificity of the realization of polydiscursive practices within commencement speech. The research involves discursive, contextual, stylistic and definitive analyses. Methodologically the study is based on the discourse analysis theory, in particular the notion of a discursive practice as a verbalized social practice makes up the conceptual basis of the research. This research draws upon a hundred commencement speeches delivered by prominent representatives of American society since 1980s till now. In brief, commencement speech belongs to institutional discourse public speech embodies. Commencement speech institutional parameters are well represented in speeches delivered by people in power like American and university presidents. Nevertheless, as the results of the research indicate commencement speech institutional character is not its only feature. Conceptual information analysis enables to refer commencement speech to didactic discourse as it is aimed at teaching university graduates how to deal with challenges life is rich in. Discursive practices of personal discourse are also actively integrated into the commencement speech discourse. More than that, existential discursive practices also find their way into the discourse under study. Commencement

    2015-04-29

    Epidemic spreading phenomena are ubiquitous in nature and society. Examples include the spreading of diseases, information, and computer viruses. Epidemics can spread by local spreading, where infected nodes can only infect a limited set of direct target nodes and global spreading, where an infected node can infect every other node. In reality, many epidemics spread using a hybrid mixture of both types of spreading. In this study we develop a theoretical framework for studying hybrid epidemics, and examine the optimum balance between spreading mechanisms in terms of achieving the maximum outbreak size. We show the existence of critically hybrid epidemics where neither spreading mechanism alone can cause a noticeable spread but a combination of the two spreading mechanisms would produce an enormous outbreak. Our results provide new strategies for maximising beneficial epidemics and estimating the worst outcome of damaging hybrid epidemics.

    For the purpose of this STI product and unless otherwise stated, hybrid fuel cell systems are power generation systems in which a high temperature fuel cell is combined with another power generating technology. The resulting system exhibits a synergism in which the combination performs with an efficiency far greater than can be provided by either system alone. Hybrid fuel cell designs under development include fuel cell with gas turbine, fuel cell with reciprocating (piston) engine, and designs that combine different fuel cell technologies. Hybrid systems have been extensively analyzed and studied over the past five years by the Department of Energy (DOE), industry, and others. These efforts have revealed that this combination is capable of providing remarkably high efficiencies. This attribute, combined with an inherent low level of pollutant emission, suggests that hybrid systems are likely to serve as the next generation of advanced power generation systems.

  7. Learning to teach effectively: Science, technology, engineering, and mathematics graduate teaching assistants' teaching self-efficacy

    Science.gov (United States)

    Dechenne, Sue Ellen

    Graduate teaching assistants (GTAs) from science, technology, engineering, and mathematics (STEM) are important in the teaching of undergraduate students (Golde & Dore, 2001). However, they are often poorly prepared for teaching (Luft, Kurdziel, Roehrig, & Turner, 2004). This dissertation addresses teaching effectiveness in three related manuscripts: (1) A position paper that summarizes the current research on and develops a model of GTA teaching effectiveness. (2) An adaptation and validation of two instruments; GTA perception of teaching training and STEM GTA teaching self-efficacy. (3) A model test of factors that predict STEM GTA teaching self-efficacy. Together these three papers address key questions in the understanding of teaching effectiveness in STEM GTAs including: (a) What is our current knowledge of factors that affect the teaching effectiveness of GTAs? (b) Given that teaching self-efficacy is strongly linked to teaching performance, how can we measure STEM GTAs teaching self-efficacy? (c) Is there a better way to measure GTA teaching training than currently exists? (d) What factors predict STEM GTA teaching self-efficacy? An original model for GTA teaching effectiveness was developed from a thorough search of the GTA teaching literature. The two instruments---perception of training and teaching self-efficacy---were tested through self-report surveys using STEM GTAs from six different universities including Oregon State University (OSU). The data was analyzed using exploratory and confirmatory factor analysis. Using GTAs from the OSU colleges of science and engineering, the model of sources of STEM GTA teaching self-efficacy was tested by administering self-report surveys and analyzed by using OLS regression analysis. Language and cultural proficiency, departmental teaching climate, teaching self-efficacy, GTA training, and teaching experience affect GTA teaching effectiveness. GTA teaching self-efficacy is a second-order factor combined from self

    Crown down preparation is the most known and described technique since the introduction of Nickel Titanium (NiTi) rotary instruments in endodontics. This technique gives good results but has limitations, such as not addressing the initial anatomy of oval or dumb-bell shaped canals. The specific design of the Protaper instruments allows use of them with a different technique and, specifically, with a brushing motion in the body of the canal. The recent introduction of hand Protaper files has expanded the range of application of this system, especially in curved canals. The 'hybrid technique', using rotary and hand files, and the advantages of the combination of both instruments, are clearly described in this article. Used with this technique, the Protaper is a very safe system to use, and more controllable, for both inexperienced and experienced practitioners alike, than other systems. To understand the precautions needed with rotary files, and how to use them to preserve the anatomy of the canal and get a tapered shaping, even in severely curved canals.

    2005-01-01

    Altering DNA copy number is one of the many ways that gene expression and function may be modified. Some variations are found among normal individuals ( 14, 35, 103 ), others occur in the course of normal processes in some species ( 33 ), and still others participate in causing various disease states. For example, many defects in human development are due to gains and losses of chromosomes and chromosomal segments that occur prior to or shortly after fertilization, whereas DNA dosage alterations that occur in somatic cells are frequent contributors to cancer. Detecting these aberrations, and interpreting them within the context of broader knowledge, facilitates identification of critical genes and pathways involved in biological processes and diseases, and provides clinically relevant information. Over the past several years array comparative genomic hybridization (array CGH) has demonstrated its value for analyzing DNA copy number variations. In this review we discuss the state of the art of array CGH and its applications in medical genetics and cancer, emphasizing general concepts rather than specific results.

    Full Text Available Mount Allison University, with about 2,400 students, is a small, undergraduate Liberal Arts and Science university with a long history of faculty-student collaboration in both research and cocurricular activities. In 2005, Mount Allison introduced the Undergraduate Teaching Internship Program in which professors and senior students collaborate in instruction. The program has quickly become for its faculty participants an important springboard for teaching innovation and scholarship. Almost immediately after its introduction, it became clear that the Undergraduate Teaching Internship Program addressed two distinct but overlapping needs—the first was predictable, the second less so: (a it presented opportunities for senior students to develop skills, knowledge and values that transcend those normally associated with undergraduate education; and (b it provided a mechanism whereby faculty could engage in scholarly reflection on teaching and Scholarship of Teaching and Learning projects. In the 5 years since its inception, internship has become not simply a peripheral program but a strong thread woven into the fabric of the university culture. While outlining some constraints of the program, this descriptive paper explains the many ways in which internship has resulted in productive, mutually beneficial collaborations between interns and their supervising professors, encouraging an even more pervasive dialogue about teaching.L’Université Mount Allisson est un petit établissement qui offre des cours dans les domaines des arts et des sciences à environ 2400 étudiants de premier cycle.

    2006-01-01

    Full Text Available Introduction. The article argues for a closer association between information seeking research and the practices of teaching information seeking. Findings are presented from a research project on information seeking, didactics and learning (IDOL investigating librarians' and teachers' experiences of teaching information seeking. Method. Thirteen teachers and five librarians, teaching 12-19 year-old students in three schools, participated. Forty-five interviews were conducted over a period of three years. Analysis. The IDOL project adopted a phenomenographic approach with the purpose of describing patterns of variation in experiences. The findings were also analysed by way of relating them to four competing approaches to the mediation of information literacy. Results. A gap was identified between experiences of teaching content that focused on sources and order, and experiences of assessment criteria applied to students' work that focused on the importance of correct facts and the analysis of information. These findings indicate a highly restricted range of teaching contents when compared with the four theoretical approaches to the mediation of information literacy. Conclusion. Teaching information seeking might be enhanced by a wider repertoire of contents reflecting more varied theoretical understanding developed in information seeking research, particularly as regards the importance of content and context related to user perspectives.

    Full Text Available As research and funding continue to replace teaching as the central mission in more colleges and universities, nursing faculty will be expected to engage in research endeavours as proof of scholarship involvement. However, the multiple roles of the nursing faculty coupled with the pressure to engage in research and funding endeavours have led to increased stress and burnout and increased attrition rate. The purpose of this paper is to delineate the expected roles of the nursing faculty related to the trilogy of teaching, research and service and recommend that colleges/universities recognize not only research as scholarship, but also teaching and service. An integrative review of the literature using books and journals from nursing and other relevant disciplines related to the multiple roles of nursing faculty was conducted. Teaching is a vital role and should remain the central mission of colleges/universities to ensure effective pedagogy. Institutions of higher learning should adapt an umbrella of scholarship under which falls teaching, research, and service; thus, teaching would be considered scholarship.

    Full Text Available A hedge is a mitigating word or sound used to lessen the impact of an utterance. It can be an adjective, for example, ‘Small potato me is not as strong as you’; or an adverb: ‘I maybe can swim faster than you’, while it can also consist of clauses, that it could be regarded as a form of euphemism which should be taught as a main topic in English class of schools around the world. For instance, in Hong Kong schools, based on my observation while teaching in a number of primary and secondary English courses as a tutor, students report that their school teachers usually emphasize the teaching of all cohesive devices in terms of skills of writing while they neglect to explain the importance of the use of hedges in order to show euphemism. In this study, I would adopt Corpus Linguistics, a division of applied linguistics, as methodology to discover a great deal of hedges employed by so-called native speakers of English, for promoting the idiomatic usage of hedges in writing, nevertheless in speaking, so as to help teachers gain resources and inspiration in teaching to students the appropriate English hedges as a consequence of the author’s hard effort while revealing from the selected corpora of this paper.

  15. Hybrid Arrays for Chemical Sensing

    Science.gov (United States)

    Kramer, Kirsten E.; Rose-Pehrsson, Susan L.; Johnson, Kevin J.; Minor, Christian P.

    In recent years, multisensory approaches to environment monitoring for chemical detection as well as other forms of situational awareness have become increasingly popular. A hybrid sensor is a multimodal system that incorporates several sensing elements and thus produces data that are multivariate in nature and may be significantly increased in complexity compared to data provided by single-sensor systems. Though a hybrid sensor is itself an array, hybrid sensors are often organized into more complex sensing systems through an assortment of network topologies. Part of the reason for the shift to hybrid sensors is due to advancements in sensor technology and computational power available for processing larger amounts of data. There is also ample evidence to support the claim that a multivariate analytical approach is generally superior to univariate measurements because it provides additional redundant and complementary information (Hall, D. L.; Linas, J., Eds., Handbook of Multisensor Data Fusion, CRC, Boca Raton, FL, 2001). However, the benefits of a multisensory approach are not automatically achieved. Interpretation of data from hybrid arrays of sensors requires the analyst to develop an application-specific methodology to optimally fuse the disparate sources of data generated by the hybrid array into useful information characterizing the sample or environment being observed. Consequently, multivariate data analysis techniques such as those employed in the field of chemometrics have become more important in analyzing sensor array data. Depending on the nature of the acquired data, a number of chemometric algorithms may prove useful in the analysis and interpretation of data from hybrid sensor arrays. It is important to note, however, that the challenges posed by the analysis of hybrid sensor array data are not unique to the field of chemical sensing. Applications in electrical and process engineering, remote sensing, medicine, and of course, artificial

      Language is not only part of culture, but also the carrier. The relationship between them decides the important role of culture teaching in language teaching. However, some problems still exist in college English teaching. For example, classroom English teaching time is not enough for culture teaching; English learners’native language thinking has negative transfer in the target language learning, etc.. In order to solve these problems, this paper tends to discuss whether English teaching should put an emphasis on Big-C Culture or Little-c Culture.

  17. Creativity in Teaching

    2016-12-01

    Full Text Available Background: The research of effective teaching is an actual problem of modern linguistics because of active promotion of its unequal manifestations and amplification of the functional load in various sectors of society. Purpose: The purpose of the analysis is to determine the qualifying and classifying features of creative and effective teacher. Results: A foreign language teacher should develop an attractive manner of communication with students. His straightforward behaviour may be expressed in non-verbal communication, through using sympathetic gestures, voice variation, smile and verbal communication expressed through a good sense of humour, personal examples, using words “we” and “our”. This manner of communication provides for a favourable condition for an atmosphere of open-mindedness and mutual understanding. A creative attitude of a teacher towards the organization of a teaching process is related to the updating of the features like fluidity understood as a spontaneous reaction during classes. The teacher as a person who creates and organises a teaching unit should possess leader’s features. Gaining a position of a group leader provides for an opportunity to arrange undisturbed work without any communication misunderstandings. Learners are given precisely formulated instructions, do the tasks in an effective and efficient manner. Therefore, it should be emphasized that a creative teacher should enjoy the features of a reflective practitioner. Being which constantly learns and improves his qualifications, studies and examines his teaching techniques, introduces changes and some time or another revisits his “beaten tracks”, breaking down routine and habits. Getting rid of habits and routines, teaching in harmony with himself, as well as appropriate selection of methods do guarantee a high comfort of work in a well-motivated group, where due to teacher’s creativity a teaching success is achieved, as expressed in

    Up to now, hybrid systems have been adapted to their specific requirements in the various applications for trucks, buses as well as mobile and building machines. From a technical point of view, this does indeed result in optimized hybrid drives for each single vehicle application, but due to small volumes, such single developments are critical from a business point of view. ZF Friedrichshafen AG is providing a solution to the technical and economical requirements of the cost-sensitive CV segment in the form of a modular CV parallel hybrid platform composed of a hybrid module system, an inverter, a battery system, and a hybrid software integrated into the overall vehicle. Thanks to the intelligent combination of assemblies and the use of as many identical parts as possible, platforms are realized which cover power ranges between 60 and 120 kW, voltage ranges between 350 and 650 V, and battery capacities between 2 and 4 kWh. The dimensions of the platform elements are such that integration into the diverse commercial vehicle applications is made easy. The hybrid software required for the vehicle-specific functions is also configurable for the mentioned CV applications. (orig.)

    Research on teaching methods in nursing education was categorized into studies on media, CAI, and other nontraditional instructional strategies. While the research differed, some generalizations may be made from the findings. Multimedia, whether it is used for individual or group instruction, is at least as effective as traditional instruction (lecture and lecture-discussion) in promoting cognitive learning, retention of knowledge, and performance. Further study is needed to identify variables that may influence learning and retention. While learner attitudes toward mediated instruction tended to be positive, investigators failed to control for the effect of novelty. Control over intervening variables was lacking in the majority of studies as well. Research indicated that CAI is as effective as other teaching methods in terms of knowledge gain and retention. Attitudes toward CAI tended to be favorable, with similar problems in measurement as those evidenced in studies of media. Chang (1986) also recommends that future research examine the impact of computer-video interactive instruction on students, faculty, and settings. Research is needed on experimental teaching methods, strategies for teaching problem solving and clinical judgment, and ways of improving the traditional lecture and discussion. Limited research in these areas makes generalizations impossible. There is a particular need for research on how to teach students the diagnostic reasoning process and encourage critical thinking, both in terms of appropriate teaching methods and the way in which those strategies should be used. It is interesting that few researchers studied lecture and lecture-discussion except as comparable teaching methods for research on other strategies. Additional research questions may be generated on lecture and discussion in relation to promoting concept learning, an understanding of nursing and other theories, transfer of knowledge, and development of cognitive skills.

    1994-01-01

    A test planting of 30 first- and second-generation pitch x loblolly pine (pinus rigida x P. taeda) hybrids was established on a West Virginia minesoil in 1985. The site was considered orphaned because earlier attempts at revegetation were unsuccessful. The soil was acid (pH 4.6), lacking in nutrients, and compacted. Vegetation present at the time of planting consisted of a sparse cover of tall fescue (Festuca arundinacea) and poverty grass (Danthonia spicata) and a few sourwood (Oxydendrum arboreum) and mountain laurel (Kalmia latifolia) seedlings. In the planting trial, 30 different hybrids were set out in 4 tree linear plots replicated 5 times. The seedlings had been grown in containers for 1 yr before outplanting. Evaluations made after 6 growing seasons showed overall plantation survival was 93%; six hybrids and one open-pollinated cross survived 100%. Individual tree heights ranged from 50 to 425 cm with a plantation average of 235 cm (7.7 ft). Eleven of the hybrids had average heights that exceeded the plantation average. Another test planting of tree and shrub species on this site has very poor survival. Therefore, pitch x loblolly hybrid pine can be recommended for reclaiming this and similar sites

    The use of nuclear fusion to produce fuel for nuclear fission power stations is discussed in the context of a crucial need for future energy options. The fusion hybrid is first considered as an element in the future of nuclear fission power to provide long term assurance of adequate fuel supplies for both breeder and convertor reactors. Generic differences in neutronic characteristics lead to a fuel production potential of fusion-fission hybrid systems which is significantly greater than that obtainable with fission systems alone. Furthermore, cost benefit studies show a variety of scenarios in which the hybrid offers sufficient potential to justify development costs ranging in the tens of billions of dollars. The hybrid is then considered as an element in the ultimate development of fusion electric power. The hybrid offers a near term application of fusion where experience with the requisite technologies can be derived as a vital step in mapping a credible route to eventual commercial feasibility of pure fusion systems. Finally, the criteria for assessment of future energy options are discussed with prime emphasis on the need for rational comparision of alternatives

In this type of counteractive behavior, a “teacher”, ostensibly helping his or her rival to learn something, really teaches the rival useless or disadvantageous things. This interaction is an object of interdisciplinary research related to the theory of human capital, the theory of agency, knowledge management, the theory of conflict, and to social and educational psychology. Examples of ThT in real life, and results of experiential studies, including the administration of a survey concerning people’s beliefs about teaching “with evil intent”, and a set of experiments with participation of adults and children, have been described. Possible directions of artificial intelligence systems development related to ThT are described.

    Full Text Available Hybrid dysfunction, a common feature of reproductive barriers between species, is often caused by negative epistasis between loci ("Dobzhansky-Muller incompatibilities". The nature and complexity of hybrid incompatibilities remain poorly understood because identifying interacting loci that affect complex phenotypes is difficult. With subspecies in the early stages of speciation, an array of genetic tools, and detailed knowledge of reproductive biology, house mice (Mus musculus provide a model system for dissecting hybrid incompatibilities. Male hybrids between M. musculus subspecies often show reduced fertility. Previous studies identified loci and several X chromosome-autosome interactions that contribute to sterility. To characterize the genetic basis of hybrid sterility in detail, we used a systems genetics approach, integrating mapping of gene expression traits with sterility phenotypes and QTL. We measured genome-wide testis expression in 305 male F2s from a cross between wild-derived inbred strains of M. musculus musculus and M. m. domesticus. We identified several thousand cis- and trans-acting QTL contributing to expression variation (eQTL.

The number and clustering of trans eQTL-but not cis eQTL-were substantially lower when mapping was restricted to a 'fertile' subset of mice, providing evidence that trans eQTL hotspots are related to sterility. Functional annotation of transcripts with eQTL provides insights into the biological processes disrupted by sterility loci and guides prioritization of candidate genes. Using a conditional mapping approach, we identified eQTL dependent on interactions between loci, revealing a complex system of epistasis. Our results illuminate established patterns, including the role of the X chromosome in hybrid sterility. The integrated mapping approach we employed is

    The High Field Laboratory for Superconducting Materials was established in April 1981 at Tohoku University in order to provide research facilities for the development of superconducting materials suitable for superconducting magnets for the plasma confinement in fusion reactors. Main facilities of this laboratory are three hybrid magnets up to 30 Tesla dc magnetic fields with inner bores from 32 to 52mm in diameter. The magnets consist of superconducting outer solenoids and water-cooled inner ones with a maximum steady power dissipation of 8 MW. The design and construction of these three hybrid magnets have finished in last three years, and two of them (HM-3;20T, 32 mm bore and HM-2; 23T, 52 mm bore) have already opened to scientists and engineers in the superconductivity and other fields. The rated field of the third hybrid magnet (HM-1) is 31 (or 29) Tesla in a bore of 32 (or 52) mm in diameter. By this hybrid system we have succeeded to produce 29.3 Tesla on April 21, 1984. Detailed descriptions are presented on the superconducting magnets, power supplies and cooling systems for them, water-cooled magnets, dc-high power source and water-cooled system for them, the monitoring and control system for the hybrid magnets including a super-minicomputer system, a hard-wired interlock system for the safety of human beings and machines, and so on.

  4. Strategies for Teaching Astronomy

    Bennett, J.

    2000-12-01

    No matter whether you are teaching school children, undergraduates, or colleagues, a few key strategies are always useful. I will present and give examples for the following five key strategies for teaching astronomy. 1. Provide a Contextual Framework: It is much easier to learn new facts or concepts if they can be ``binned" into some kind of pre-existing mental framework. Unless your listeners are already familiar with the basic ideas of modern astronomy (such as the hierarchy of structure in the universe, the scale of the universe, and the origin of the universe), you must provide this before going into the details of how we've developed this modern picture through history. 2. Create Conditions for Conceptual Change: Many people hold misconceptions about astronomical ideas. Therefore we cannot teach them the correct ideas unless we first help them unlearn their prior misconceptions. 3. Make the Material Relevant: It's human nature to be more interested in subjects that seem relevant to our lives. Therefore we must always show students the many connections between astronomy and their personal concerns, such as emphasizing how we are ``star stuff" (in the words of Carl Sagan), how studying other planets helps us understand our own, and so on. 4. Limit Use of Jargon: The number of new terms in many introductory astronomy books is larger than the number of words taught in many first courses in foreign language. This means the books are essentially teaching astronomy in a foreign language, which is a clear recipe for failure. We must find ways to replace jargon with plain language. 5. Challenge Your Students: Don't dumb your teaching down; by and large, students will rise to meet your expectations, as long as you follow the other strategies and practice good teaching.

    This is a short introduction about me, description of different teaching methods, which is used in my teaching practice of Geography, biology and GIS systems education. The main part is tell about practical lesson with lab Vernier. My name is Svetlana Gornostaeva. I am a geography, biology and GIS systems teacher in Tallinn Mustjõe Gymnasium (www.mjg.ee) and private school Garant (http://www.erakoolgarant.ee/). In my teaching practice I do all to show that science courses are very important, interesting, and do not difficult. I use differentiated instruction methods also consider individual needs. At lessons is used different active teaching methods such as individual work of various levels of difficulty, team works, creative tasks, interactive exercises, excursions, role-playing games, meeting with experts. On my lessons I use visual aids (maps, a collection of rocks and minerals, herbarium, posters, Vernier data logger). My favorite teaching methods are excursions, meeting with experts and practical lesson with lab Vernier. A small part of my job demonstrate my poster. In the next abstract I want to bring a one practical work with Vernier which I do with my students, when we teach a theme "Atmosphere and climate". OUTDOOR LEARNING. SUBJECT "ATMOSPHERE AND CLIMATE". WEATHER OBSERVATIONS WITH VERNIER DATA LOGGER. The aim: students teach to use Vernier data logger and measure climatic parameters such as: temperature, humidity, atmospheric pressure, solar radiation, ultraviolet light radiation, wind speed. In working process pupils also teach work together, observe natural processes, analyze. Children are working by small groups, 4-5 in each group. Every one should personally measure all parameters and put numbers into the table. After it group observe cloudiness, analyze table and give conclusion "Is at this moment dominates cyclone or anticyclone ?". Children really like this kind of job. Vernier data logger it is really fantastic tool. It is mobile lab. This

  11. Teaching science in museums

    Science.gov (United States)

    Tran, Lynn Uyen

    Museums are free-choice, non-threatening, non-evaluative learning and teaching environments. They enable learners to revisit contents, authentic objects, and experiences at their own leisure as they continually build an understanding and appreciation of the concepts. Schools in America have used museums as resources to supplement their curriculum since the 19 th century. Field trip research is predominantly from the teachers' and students' perspectives, and draws attention to the importance for classroom teachers and students to prepare prior to field trips, have tasks, goals, and objectives during their time at the museum, and follow up afterwards. Meanwhile, museum educators' contributions to field trip experiences have been scantily addressed. These educators develop and implement programs intended to help students' explore science concepts and make sense of their experiences, and despite their limited time with students, studies show they can be memorable. First, field trips are a break in the usual routine, and thus have curiosity and attention attracting power. Second, classroom science teaching literature suggests teachers' teaching knowledge and goals can affect their behaviors, and in turn influence student learning. Third, classroom teachers are novices at planning and implementing field trip planners, and museum educators can share this responsibility. But little is reported on how the educators teach, what guides their instruction, how classroom teachers use these lessons, and what is gained from these lessons. This study investigates two of these inquiries. The following research questions guided this investigation. (1) How do educators teaching one-hour, one-time lessons in museums adapt their instruction to the students that they teach? (2) How do time limitations affect instruction? (3) How does perceived variability in entering student knowledge affect instruction? Four educators from two museums took part in this participant observation study to

    2005-01-01

    We estimate the sizeable cross section for deep exclusive electroproduction of an exotic J PC = 1 -+ hybrid meson in the Bjorken regime. The production amplitude scales like the one for usual meson electroproduction, i.e. as 1/Q 2 . This is due to the non-vanishing leading twist distribution amplitude for the hybrid meson, which may be normalized thanks to its relation to the energy momentum tensor and to the QCD sum rules technique. The hard amplitude is considered up to next-to-leading order in as and we explore the consequences of fixing the renormalization scale ambiguity through the BLM procedure. (author)

  15. Inference in hybrid Bayesian networks

    International Nuclear Information System (INIS)

    Langseth, Helge; Nielsen, Thomas D.; Rumi, Rafael; Salmeron, Antonio

    2009-01-01

    Since the 1980s, Bayesian networks (BNs) have become increasingly popular for building statistical models of complex systems. This is particularly true for boolean systems, where BNs often prove to be a more efficient modelling framework than traditional reliability techniques (like fault trees and reliability block diagrams). However, limitations in the BNs' calculation engine have prevented BNs from becoming equally popular for domains containing mixtures of both discrete and continuous variables (the so-called hybrid domains). In this paper we focus on these difficulties, and summarize some of the last decade's research on inference in hybrid Bayesian networks. The discussions are linked to an example model for estimating human reliability.

    A hybrid magnetic approach, merging two different magnetic core properites such as ferrite and iron powder cores, is an effective solution for power converter applications. It can offer similar magnetic properties to that of magnetic powder cores but showing less copper loss than powder cores....... In order to prevent ferrite core saturation, placing an effective air gap within the ferrite core is a key method to obtain optimum hybrid magnetic performance. Furthermore, a relatively large inductance at low loading current is an excellent way to minimze power loss in order to achieve high efficiency...

  14. ADVANCED HYBRID PARTICULATE COLLECTOR

    Energy Technology Data Exchange (ETDEWEB)

    Ye Zhuang; Stanley J. Miller; Michelle R. Olderbak; Rich Gebert

    2001-12-01

    A new concept in particulate control, called an advanced hybrid particulate collector (AHPC), is being developed under funding from the U.S. Department of Energy. The AHPC combines the best features of electrostatic precipitators (ESPs) and baghouses in an entirely novel manner. The AHPC concept combines fabric filtration and electrostatic precipitation in the same housing, providing major synergism between the two methods, both in the particulate collection step and in transfer of dust to the hopper. The AHPC provides ultrahigh collection efficiency, overcoming the problem of excessive fine-particle emissions with conventional ESPs, and solves the problem of reentrainment and re-collection of dust in conventional baghouses. Phase I of the development effort consisted of design, construction, and testing of a 5.7-m{sup 3}/min (200-acfm) working AHPC model. Results from both 8-hr parametric tests and 100-hr proof-of-concept tests with two different coals demonstrated excellent operability and greater than 99.99% fine-particle collection efficiency. Since all of the developmental goals of Phase I were met, the approach was scaled up in Phase II to a size of 255 m{sup 3}/min (9000 acfm) (equivalent in size to 2.5 MW) and was installed on a slipstream at the Big Stone Power Plant. For Phase II, the AHPC at Big Stone Power Plant was operated continuously from late July 1999 until mid-December 1999. The Phase II results were highly successful in that ultrahigh particle collection efficiency was achieved, pressure drop was well controlled, and system operability was excellent. For Phase III, the AHPC was modified into a more compact configuration, and components were installed that were closer to what would be used in a full-scale commercial design. The modified AHPC was operated from April to July 2000. While operational results were acceptable during this time, inspection of bags in the summer of 2000 revealed some membrane damage to the fabric that appeared to be

    Grammar is an important part of language learning. In order for students to have a functional knowledge of a language (in other words, that they can spontaneously produce language) they must have at least some knowledge about the grammatical con⁃structs of the language in question. How grammar can be taught? Considering various second language teaching methods, teaching grammar through Communicative Language Teaching Approach is the most talked. Emphasis in this article is put on the applica⁃tion of Communicative Language Teaching Approach in grammar teaching in college English classes.
