    Clinical practice placements are an essential component of pre-registration nursing programmes. Integration into a new team in an unfamiliar setting, which has its own values, practices, culture and language, can be stressful for nursing students. This article presents and discusses students' reflections on preparing for, entering and leaving practice placements. Ten students who participated in fortnightly group reflective sessions, discussed and analysed their learning experiences while on practice placements in an acute hospital. The challenges the students encountered were deconstructed using a group narrative approach. The students experienced ethical dilemmas around patient dignity, consent and advocacy as well as factors external to the practice setting, such as navigating systems and processes to access information before starting practice placements, managing household duties and academic workloads while working long shifts, and managing fatigue and loneliness. The students devised recommendations for other students to enable them to navigate their practice placements effectively and enhance their learning experience. Raising awareness among academic and practice placement staff of the challenges students encounter before and during their practice placement is essential to assist students to succeed and maximise their learning potential.

    The employment market for graduates is competitive with employers requiring appropriate work experience in addition to academic qualifications. Sandwich courses, where up to a year is spent in industry, provide an opportunity for structured work experience to be gained alongside studying. Benefits of placements include improved academic performance and the development of transferable skills to increase employability. This paper evaluates the impact of placements on academic performance and graduate employment among management students. Analysing performance data and graduate destinations data, results indicate that management students completing a placement are more likely to perform better academically with improvements in their personal grades between year 2 and the final year. Additionally, a qualitative themed analysis of student experiences indicates placement students feel more confident in engaging with the graduate recruitment process, with a better understanding of their personal skills and an ability to articulate their experience in relation to the workplace.

    While placements in external locations are being increasingly used in dental education globally, few studies have explored the student learning experience at such placements. The purpose of this study was to investigate student experiences while on external placement in a baccalaureate dental hygiene program. A self-reporting questionnaire was distributed to final-year dental hygiene students (n=77) at the University of Newcastle, Australia, in 2010. The questionnaire included questions regarding the type of placement, experiences offered, supervision, resources available, and lasting impressions. Responding students were generally positive about their external placement experience and indicated that the majority of facilities provided them with the opportunity to provide direct patient care and perform clinical tasks typical of a practicing hygienist. However, there was a statistically significant difference in their opinions about discipline-focused and community placements. Students indicated that their external placement experience provided opportunities to learn more about time and patient management, including hands-on experience with specific clinical tasks. Ongoing evaluations are necessary to ensure that external placements meet both student needs and intended learning outcomes within dental hygiene programs.

    It is vital that children's nursing students are fit for practice when they qualify and are able to meet various essential skills as defined by the Nursing and Midwifery Council (NMC). To gain the knowledge and skills required, students need placements in areas where high dependency and potentially intensive care are delivered. Efforts to maximise the number of students experiencing intensive care as a placement have led to the development of the paediatric intensive care unit (PICU) rotation, increasing placements on the PICU from 5 to 40 per cent of the student cohort per year. The lecturer practitioner organises the rotation, providing credible links between university and practice areas, while supporting students and staff in offering a high-quality placement experience. Students say the rotation offers a positive insight into PICU nursing, helping them develop knowledge and skills in a technical area and creating an interest in this specialty.

    Many nursing students enter undergraduate programmes with preconceived ideas about their future nursing careers, and intend to practice in particular areas such as midwifery or paediatrics. Through clinical placements, students are exposed to different clinical areas and professional socialization is facilitated. However, little is known about the influence of clinical placements on students' career intentions. This paper reports nursing findings drawn from a large qualitative study conducted in Victoria, Australia that sought to explore the influence of health professional students' clinical placements on their future career intentions. Participants were invited to be involved in either face-to-face or focus group interviews depending upon their own preference. Thematic data analysis revealed three main themes: 're-affirming career choice', 'working in a particular area' and 'work location'. Findings from the study add to our understanding of factors influencing nursing students' planning for their future careers including the impact of clinical placements.

    Introduction: Radiation therapy students at Queensland University of Technology (QUT) attend clinical placements at five different clinical departments with varying resources and support strategies. This study aimed to determine the relative availability and perceived importance of different factors affecting student support while on clinical placement. The purpose of the research was to inform development of future support mechanisms to enhance radiation therapy students’ experience on clinical placement. Methods: This study used anonymous Likert-style surveys to gather data from years 1 and 2 radiation therapy students from QUT and clinical educators from Queensland relating to availability and importance of support mechanisms during clinical placements in a semester. Results: The study findings demonstrated student satisfaction with clinical support and suggested that level of support on placement influenced student employment choices. Staff support was perceived as more important than physical resources; particularly access to a named mentor, a clinical educator and weekly formative feedback. Both students and educators highlighted the impact of time pressures. Conclusions: The support offered to radiation therapy students by clinical staff is more highly valued than physical resources or models of placement support. Protected time and acknowledgement of the importance of clinical education roles are both invaluable. Joint investment in mentor support by both universities and clinical departments is crucial for facilitation of effective clinical learning.

    The aim was to investigate the impact of a new structure for supporting students and mentors in practice placements (Placement Development Teams) in fostering interprofessional education from the perspective of non-medical health care students and staff. Interprofessional education is an important international issue which received significant impetus in the UK as a result of many high-profile cases where uni-professional boundaries and cultures have contributed to adverse patient and client outcomes. This study was part of a longitudinal qualitative evaluation of Placement Development Teams. The design for this stage was cross-sectional. Data were collected using telephone interviews with key educational stakeholders in trusts and Strategic Health Authorities and focus groups with third-year non-medical health care students working in the south-west peninsula of England. Students' focus group data indicated that interprofessional support and learning was key. Students had mixed views on how much they valued support gained from staff and students from other professions. Staff data indicated that they facilitated communication. Staff discussed their practical activities which made a difference and helped change the organisational culture in favour of interprofessional education. If interprofessional education in clinical practice is to be effective, it needs local facilitation and structures that support it. Placement Development Teams can provide this. The 'best' means of 'doing interprofessional education' in clinical practice and its impact on patient outcomes requires further large-scale research work with rigorous methodologies at a national level. To embed interprofessional education in practice-based professions' curricula and clinical placements requires active, supportive structures and local facilitation. Structures such as Placement Development Teams can help to achieve this where organisational cultures are influenced by committed staff. Students require

    Physiotherapists have an established role in occupational health, and their undergraduate education is important in preparation for such practice. At the University of South Australia students undertake small occupational health and safety projects on-site in industry. These industry placements are a challenge to secure, and the supervising industry hosts are generally not physiotherapists. This study sought to uncover influences involved when organisations consider hosting students. A qualitative approach was taken where semistructured interviews were conducted with a purposeful sample of nine industry hosts to explore their views about placements. Seven hosts were managers and two were physiotherapists. Three main themes came from the data analysis. The first and overriding theme was the "mutual benefit" in hosting students, where students gained valuable experience from working in industry on real problems, and hosts gained from the students' activities. The second theme related to what the host organisation gained - "the transfer and acquisition of resources, knowledge and skills" provided by the students, the nature and quality of which were important to hosts. The last theme had two components of "timing and time." The timing of student activities and how that fits with other activities simultaneously happening within the organisation was an important factor. Finally, participants reported consideration of the time taken to supervise the students in relation to time saved through student activities which assisted the host organization. Knowldege about influencing factors gained from this study may assist physiotherapy educators in securing student placements in industry.

    Simzar, Rahila M; Domina, Thurston; Tran, Cathy

    2016-01-01

    This study uses student panel data to examine the association between Algebra placement and student motivation for mathematics. Changes in achievement goals, expectancy, and task value for students in eighth grade Algebra are compared with those of peers placed in lower-level mathematics courses (N = 3,306). In our sample, students placed in Algebra reported an increase in performance-avoidance goals as well as decreases in academic self-efficacy and task value. These relations were attenuated for students who had high mathematics achievement prior to Algebra placement. Whereas all students reported an overall decline in performance-approach goals over the course of eighth grade, previously high-achieving students reported an increase in these goals. Lastly, previously high-achieving students reported an increase in mastery goals. These findings suggest that while previously high-achieving students may benefit motivationally from eighth grade Algebra placement, placing previously average- and low-performing students in Algebra can potentially undermine their motivation for mathematics.

    2016-08-01

    Placements provide opportunities for students to develop practice skills in professional settings. Learning in placements may be challenging for culturally and linguistically diverse (CALD) students, international students, or those without sufficient English proficiency for professional practice. This study investigated whether these factors, which are hypothesized to influence acculturation, predict poor placement outcome. Placement outcome data were collected for 854 students who completed 2747 placements. Placement outcome was categorized into 'Pass' or 'At risk' categories. Multilevel binomial regression analysis was used to determine whether being CALD, an international student, speaking 'English as an additional language', or a 'Language other than English at home' predicted placement outcome. In multiple multilevel analysis speaking English as an additional language and being an international student were significant predictors of 'at risk' placements, but other variables tested were not. Effect sizes were small indicating untested factors also influenced placement outcome. These results suggest that students' English as an additional language or international student status influences success in placements. The extent of acculturation may explain the differences in placement outcome for the groups tested. This suggests that learning needs for placement may differ for students undertaking more acculturative adjustments. Further research is needed to understand this and to identify placement support strategies.

    To learn how students experience clinical placements in a setting of diversity and how they cope with the emotional challenges involved. This study is based on inductive, qualitative research undertaken with Israeli nursing students. In-depth interviews were conducted with 20 students: 10 Arabs (5 men and 5 women), 9 Jews (2 men and 7 women), and 1 Circassian. The interviews were analyzed through coding and categorization. The students' experiences are characterized by emotional strains of various sorts-stress, ambivalence, disgust, frustration, and conflict-that arise in three types of relationships: relationships with patients, with the clinical instructors, and with other students who are on their teams. The data show that diversity has an impact on all these relationships. The data further show that the students cope with the emotional strains by using several strategies of emotional work: distancing, self-strengthening, self-motivation work, and minimizing significance. (a) Nursing students' experiences during their clinical placements should be understood in terms of emotional challenges, and their emotional work and coping strategies call for appropriate forms of support. (b) The diversity of the clinical placement environment should be considered as an important factor, both in understanding students' experiences and learning processes and in designing the support that they need. Culturally diverse settings entail distinct challenges that impact students' emotional reaction to clinical work. Understanding the types of emotional work students do in the process of their clinical experience is critical for educators seeking to promote genuinely caring and effective nursing in culturally diverse settings.  © 2013 Sigma Theta Tau International.

    2008-01-01

    Each year growing numbers of undergraduate health science students, from a variety of disciplines, participate in a University of Tasmania Department of Rural Health supported rural placement program in Tasmania. This study aimed to investigate the influence rural placement and rural background had on students' intentions to live and work in a rural or remote location after graduation. Between January 2005 and December 2006, 336 students participated in the placement program. Students were requested to complete a survey at the completion of their placement. A response rate of 239 was achieved (71%). The survey measured students' stated rural career intentions and rural background status according to location of primary and secondary school attendance. A demographic analysis of respondents was undertaken and results cross tabulated according to the rural, remote and metropolitan area (RRMA) classification system. Statistical analyses, including paired t-tests and a Wilcoxon signed rank test, were conducted to compare reported mean intention to practise rurally both prior to and after placement. The results from this survey show that rural placements in the undergraduate health science programs have a predominantly positive influence on students' intention to work in a rural community post-graduation. While these findings were significant for the disciplines of nursing, medicine and allied health, the results were not significant for pharmacy students. Students' average intention to practise rurally significantly increased after the placement for students from RRMA classifications 1 and 3-5. The value of rural placements as a method for increasing health science students' intentionality to take up rural practice as a positive and viable career option is considerable.

    2014-03-01

    This paper draws on empirical fieldwork data of naturally occurring UK physiotherapy placement education to make visible how education is actually carried out and suggest what students may be learning through their placement interactions. The data challenge everyone involved in placement education design and practice to consider the values and practices students are learning to perpetuate through placement education experiences. The researcher undertook an ethnomethodologically informed ethnographic observation of naturally occurring physiotherapy placement education in two UK NHS placement sites. This study adopted a social perspective of learning to focus on the minutiae of placement educator, student and patient interaction practices during student-present therapeutic activities. Two days of placement for each of six senior students were densely recorded in real-time focussing specifically on the verbal, kinesics and proxemics-based elements of the participants' interaction practices. Repeated cycles of data analysis suggested consistent practices irrespective of the placement, educators, students or patients. The data suggest that placement education is a powerful situated learning environment in which students see, experience and learn to reproduce the physiotherapy practices valued by the local placement. Consistently, placement educators and students co-produced patient-facing activities as spectacles of physiotherapy-as-science. In each setting, patients were used as person-absent audiovisual teaching aids from which students learnt to make a case for physiotherapy intervention. The paper challenges physiotherapists and other professions using work-placement education to look behind the rhetoric of their placement documentation and explore the reality of students' learning in the field. The UK-based physiotherapy profession may wish to consider further the possible implications of its self-definition as a 'science-based healthcare profession' on its in-the-presence-of-students

The research was undertaken with primary school teachers from Bolu central district (n=100 and students who were given the test during (n=100 2009-2010 educational year. The study employing the survey model utilizes qualitative research methods. Data was collected by using interview forms which were later analyzed by content analysis. At the end of the study it was found that SBS creates feelings such as stress, fear, anxiety and curiosity and has an important effect on the identification of the future educational lives and professions of the students. SBS prevents students from socializing. Differences have been detected between the courses SBS covers and the courses studied at school. Students engage in activities such as answering test questions, taking trial tests, answering preparatory courses, receiving counseling, going to the courses and private tutoring. School administrators take the exam results very seriously. Implementations that are based on student-teacher-parent collaboration and that use selection based on ability and interests have been suggested.

  13. Precautions used by occupational health nursing students during clinical placements

    Full Text Available Protection of health care workers including students from being infected when caring for high risk patients is a major cause for concern to all promoting occupational health. Safety of every employee is mandatory. Furthermore, universal guidelines for precautions must be used by all interacting with high risk patients and clients to protect themselves and prevent the spread of infection. The aim of this paper was to ascertain the availability of universal guidelines for precautions against the spread of infection in clinical settings and determine the precautions used by OHN students during their clinical placements. To realise these objectives, a quantitative and descriptive design was followed. A purposive sampling method was used to select 45 Occupational health nursing students who participated in the study.Data was collected with the use of a structured questionnaire and the results revealed that: most units where OHN students were placed for clinical experience had guidelines for universal precautions although these were not always accessible to them; regarding compliance to universal precautions, OHN students were reportedly aware of the hazards of failure to comply although in some emergencies and where personal protective material was not available, they had to provide care without using protective equipments. Recommendations made include that employers and staff at all occupational settings must ensure that updated guidelines for universal precautions are available and accessible to every body interacting with high risk patients; health care providers and students must be fully informed about and should always adhere to universal precautions.

    2015-06-01

    This study aimed to describe perceptions of clinical placement experiences and competency development for international speech-language pathology students and to determine if these perceptions were different for domestic students. Domestic and international students at two Australian universities participated in nine focus group interviews. Thematic analysis led to the identification of two themes shared by international and domestic students and several separate themes. Shared themes identified the important influence of students' relationships with clinical educators, unique opportunities and learning that occurs on placement. International student themes included concerns about their communication skills and the impact of these skills on client progress. They also explored their adjustment to unfamiliar placement settings and relationships, preferring structured placements to assist this adjustment. Domestic student themes explored the critical nature of competency attainment and assessment on placement, valuing placements that enabled them to achieve their goals. The findings of this study suggest that international students experience additional communication, cultural and contextual demands on clinical placement, which may increase their learning requirements. Clinical education practices must be responsive to the learning needs of diverse student populations. Strategies are suggested to assist all students to adjust to the professional and learning expectations of clinical education placements.

The theme of Pre-placement Expectations incorporates participant foci on pre-conceptions of Recovery Camp. The theme of Student Learning incorporates the ways in which participants recognised the experience of Recovery Camp influenced learning. Reflections themed under the title Placement Setting include discussion of the Recovery Camp as a clinical placement. The theme of Future Practice incorporates students' reflections on how they plan to practice as nurses as a result the learning experiences of Recovery Camp. An immersive clinical placement such as Recovery Camp can influence students' perceptions of people with mental illness, have a positive impact on student learning and influence students' decisions about future practice. The learning experience of nursing students whom attend unique, recovery-orientated clinical placements can be both positive and educative. Copyright © 2016 Elsevier Ltd. All rights reserved.

    To determine the elements of quality clinical and field placements through the eyes of paramedic instructors. Qualitative study. Two large paramedic services in two countries where the entry to practice qualification for paramedics has been set at the Bachelors degree level. Fifteen purposively selected paramedic instructors were invited to voluntarily participate. The criterion for inclusion was that they had supervised at least one university paramedicine student on a field placement. Recruitment ceased when saturation was reached. Face to face semi-structured interviews were conducted with participants who were asked their views and expectations of paramedicine student clinical and field placements. Inductive thematic analysis of the transcripts was completed using Nvivo software. The elements of quality clinical and field placements from the perspective of paramedic instructors were identified. With no agreed clinical and field placement paramedicine standards in the countries studied there is variation in the focus of placements, preferred settings, and expectations. Vocationally trained paramedics favoured paramedic service placements, whilst university educated paramedics see benefits in placements in more diverse settings. Paramedic services and universities need to collaboratively address the variation in paramedicine university student clinical and field placements. Standards need to be developed that address the purpose of placements, expectations of students and instructors, and be scaffolded across the education spectrum from undergraduate student to graduate paramedic to instructor.

    Attrill, Stacie; Lincoln, Michelle; McAllister, Sue

    2016-07-16

    Health professional education programs attract students from around the world and clinical supervisors frequently report that international students find learning in clinical placement contexts particularly challenging. In existing literature clinical supervisors, who support international students on placement have identified concerns about their communication and interactions within clinical environments. However, clinical supervisors' perspectives about their experiences with international students on placement and the strategies they utilise to facilitate international student learning have not been described. As a result we have little insight into the nature of these concerns and what clinical supervisors do to support international students' competency development. Five focus group interviews were conducted with twenty Speech-Language Pathology clinical supervisors, recruited from 2 Australian universities. Interview data were analysed thematically. Themes identified were interpreted using cognitive load and sociocultural learning theories to enhance understanding of the findings. Four themes were identified: 'Complex teaching and learning relationships', 'Conceptions of students as learners'; Student communication skills for professional practice', and 'Positive mutual learning relationships'. Findings indicated that clinical supervisors felt positive about supporting international students in clinical placements and experienced mutual learning benefits. However, they also identified factors inherent to international students and the placement environment that added to workload, and made facilitating student learning complex. Clinical supervisors described strategies they used to support international students' cultural adjustment and learning, but communication skills were reported to be difficult to facilitate within the constraints of placements. Future research should address the urgent need to develop and test strategies for improving international

    This paper first reviews key concepts in language testing and discusses the use of the English Language Placement Test administered at the Catholic University of Rio de Janeiro to computer science students, who are required t o take one of the two ESP courses offered by the English program. The analysis of the scores on two versions of a test administered to two different groups of computer science students who took the examination in sequential semesters is presented. For the original test, it em facility and it em discrimination were calculated, then overall test reliability was estimated. The statistics were carefully examined and a number of t he test items were eliminated, revamped or replaced in creating a revised version of the test. This modified and improved version of the test was then administered to a second group of students and the same statistics were applied once more. The results are discussed in terms of the importance of item analysis and revision for providing more consistent and accurate language testing instruments.

  1. Supporting culturally and linguistically diverse students during clinical placement: strategies from both sides of the table.

    O'Reilly, Sharleen L; Milner, Julia

    2015-10-15

    Increasing proportions of Culturally and Linguistically Diverse (CALD) students within health professional courses at universities creates challenges in delivering inclusive training and education. Clinical placements are a core component of most health care degrees as they allow for applied learning opportunities. A research gap has been identified in regard to understanding challenges and strategies for CALD students in health professional placements. A key stakeholder approach was used to examine barriers and enablers experienced by CALD students in clinical placement. Semi-structured focus groups with healthcare students (n = 13) and clinical placement supervisors (n = 12) were employed. The focus groups were analysed using open coding and thematic analysis. Three main barrier areas were identified: placement planning and preparation; teaching, assessment and feedback; and cultural and language issues. Potential solutions included addressing placement planning and preparation barriers, appropriate student placement preparation, pre-placement identification of higher risk CALD students, and diversity training for supervisors. For the barrier of teaching, assessment & feedback, addressing strategies were to: adapt student caseloads, encourage regular casual supervisor-student conversations, develop supportive placement delivery modes and structures, set expectations early, model the constructive feedback process, use visual aids, and tailor the learning environment to individual student needs. The enablers for cultural & language issues were to: build language and practical approaches for communication, raise awareness of the healthcare system (how it interacts with healthcare professions and how patients access it), and initiate mentoring programs. The findings suggest that teaching and learning strategies should be student-centred, aiming to promote awareness of difference and its impacts then develop appropriate responses by both student and teacher

    2008-05-15

    Purpose: To assess undergraduate radiography student perception of clinical placements and to evaluate their clinical learning experiences. Methods: To evaluate student perception of clinical placements, a Likert-scale questionnaire was used to assess clinical practice, the practice-learning environment. One hundred and seventy-eight undergraduate [student] radiographers participated in the study. Results: The students indicated they had adequate and enjoyed their time on the clinical placement. They also indicated the qualified staff was supportive, friendly and approachable. The students were able to achieve their learning outcomes during the placement. However placement venues, according to the students, had inadequate learning resources. No radiographic/medical imaging research findings, whether locally generated or otherwise, were used in clinical practice. Conclusions: Clinical placements had adequate student support. It provided a pleasant learning experience for the students and it enhanced their skills. Staff was willing and available to assist learning. Nevertheless, the training institutions, professional body and clinical placement providers need to make an effort to address inadequate learning resources (e.g. IT, library, study rooms) as well as the non-utilization of radiographic/medical imaging research findings.

    This exploratory case study examined an interprofessional placement of undergraduate students from nutrition, nursing, early childhood education, and child and youth care who collaborated to develop and deliver four healthy-living modules to secondary school students in Canada. An inductive thematic analysis was used to describe the teamwork that occurred between students. Data collected included focus groups with undergraduate students and preceptors, undergraduate students' reflections and secondary school students' evaluations of the modules delivered. Two major themes that emerged from all data sources were "team functioning" and "shift in perspectives". The undergraduate students identified several ways that facilitated their successful and positive teamwork with one another and also expressed how the placement experience improved their interprofessional skills. Findings from this study are discussed in relation to contact theory (Allport, 1954) and self-presentation theory (Goffman, 1963). This study suggests that providing undergraduate students with interprofessional placements in an educational setting can enhance interprofessional teamwork opportunities for students of various disciplines.

    2014-10-01

    To record the views of final year dental hygiene students from the University of Newcastle, Australia about a placement in 17 residential aged care facilities, on the NSW Central Coast. Final year dental hygiene students undertook a 12 week placement, 1 day per week, in 1 of 17 residential aged care facilities. They were asked to participate in focus group discussions after the placement to determine their ability to transition from the classroom to the real-life experience of the residential aged care facility placement. Students felt ill-equipped for the aged care placement program even though they had attended a pre-placement orientation. Students expressed feelings of being overwhelmed by the residential aged care environment, particularly by the smells and unexpected sights of the aged, fragile and cognitively impaired residents, and the difficulties in providing them with oral hygiene care. To enable students to transition from the classroom to the aged care environment in a more effective manner, a more realistic pre-placement orientation program is necessary.

    2015-10-01

    International clinical placements provide undergraduate nursing students with the opportunity to experience or practice nursing care in diverse countries, settings, and cultures. This systematic review aims to ascertain the current knowledge on international clinical placements offered by undergraduate nursing programs in Australia. It seeks to explore three questions: (1) How have previous experiences of nursing students' international clinical placements been described? (2) How have participants and stakeholders determined if the placement has been successful? And (3) What benefits or challenges have been identified by stakeholders as a result of participating in international clinical placements? A systematic thematic synthesis was undertaken. A search of electronic databases including CINAHL, Proquest Central, Scopus, PubMed, and Health Collection was undertaken between September and October 2014. Key terms including 'international clinical placement', 'study abroad', 'international exchange', 'nursing', and 'Australia' were used to identify articles that appeared in peer-reviewed English language journals and that explored international clinical placements offered to undergraduate nursing students by Australian universities. Eight studies were identified that meet the inclusion criteria, and through thematic analysis, five key themes were identified including developing cultural awareness and competence, providing a global perspective on health care, translation of theory to practice, growing personally through reflection, and overcoming apprehension to successfully meet the challenge. A comparison search of literature from Canada and the United Kingdom revealed that similar themes occurred internationally. Although personal successes were identified by students undertaking international clinical placement, further research is required to identify all stakeholder experiences including those of the educators, the educational institutions, and travel providers

    2016-06-01

    Full Text Available This paper describes a qualitative case study that explores how twenty-three field advisors, representing three human service professions including education, nursing, and social work, experience the process of assessment with students who are struggling to meet minimum competencies in field placements. Five themes emerged from the analysis of qualitative interviews. The field advisors primary concern was the level of professional competency achieved by practicum students. Related to competency were themes concerned with the field advisor's role in being accountable and protecting the reputation of his/her profession as well as the reputation of the professional program affiliated with the practicum student's professional education. The final theme – teacher-student relationship –emerged from the data, both as a stand-alone and global or umbrella theme. As an umbrella theme, teacher-student relationship permeated each of the other themes as the participants interpreted their experiences of the process of assessment through the mentor relationships. A theoretical model was derived from these findings and the description of the model is presented. Cet article décrit une étude de cas qualitative qui explore comment vingt-trois conseillers de stages, représentant trois professions de services sociaux comprenant l’éducation, les soins infirmiers et le travail social, ont vécu l’expérience du processus d’évaluation avec des étudiants qui ont des difficultés à acquérir les compétences minimales durant les stages. Cinq thèmes ont été identifiés lors de l’analyse des entrevues qualitatives. La préoccupation principale des conseillers de stages était le niveau de compétence professionnelle acquis par les stagiaires. Les thèmes liés à la compétence étaient le rôle des conseillers de stages dans leur responsabilité pour protéger la réputation de leur profession ainsi que la réputation d’un programme professionnel

    This study investigated the changes in emotional intelligence (EI) of occupational therapy, physiotherapy, and speech pathology students (therapy students). Clinical placements have multiple benefits including the development of interprofessional skills, enhancing practice skills and interpersonal skills. Higher EI competencies have been shown to have a positive impact on patient outcomes, teamwork skills, dealing with stress, and patient satisfaction. Data for this study were collected at two time points: before third-year therapy students commenced extended clinical placements (T1 with 261 students) and approximately 7 months later after students had completed one or more clinical placements (T2 with 109 students). EI was measured using the Emotional Quotient Inventory 2.0 (EQ-i(2.0)). Only one EI score, assertiveness, demonstrated a significant decline. No EI score showed a significant increase. A third or more of the students showed increases of five points or more in self-actualisation, emotional expression, independence, reality testing and optimism. However, of concern were the five EI scores where therapy students' EI scores decreased by more than five points: assertiveness (where 38% of students declined), problem solving (37%), impulse control (35%), self-actualisation (35%), and stress tolerance (33%). With EI scores declining for some students during clinical placements, there are implications for clinical supervisors and interprofessional facilitators as clinical performance may decline concurrently. There is a range of potential reasons that clinical placements could negatively influence the EI competencies of a therapy student, including poor clinical supervision, conflict between a student, and supervisor and failing a clinical placement. The research suggests that interprofessional facilitators and university educators might consider students undertaking EI tests before clinical placements.

    The rigorous efforts students put into baccalaureate nursing programs to become a professional nurse is compounded by their need to have a sense of belonging in their clinical placements. In addition, the students' perceived stress may contribute to their physiological and psychological wellbeing undermining academic achievements and confidence. A sense of belonging and perceived stress have research history in psychological and sociological realms; but not used together in the nursing profession as applied in clinical placements. The Perceived Stress Scale is a psychological instrument used globally; however, the Belongingness Scale-Clinical Placement Experience (BES-CPE) measurement tool has not been used in published research in the United States. A descriptive correlational research design examining the relationship between a sense of belonging and perceived stress among baccalaureate nursing students in clinical placements. Three measurement tools were used for data collection: BES-CPE, Perceived Stress Scale (PSS-10) and demographic questionnaire. Students were able to access the online survey through SurveyMonkey®. A national study was conducted using 1296 volunteer nursing students from the National Student Nurses Association (NSNA) database. These nursing students were currently enrolled in a baccalaureate nursing program, 18years of age and completed at least one clinical experience. The findings from this study revealed a statistically significant low inverse relationship (r=-.277) between a sense of belonging and perceived stress among baccalaureate nursing students in their clinical placements. The findings also supported the use of BES-CPE as a reliable and valid measurement tool for nursing students in clinical placements. The results of this study supported the concept of a sense of belonging as a fundamental human need, having a positive influence and impact on students' learning, motivation and confidence. In contrast, perceived stress has

    Full Text Available This quantitative descriptive study examined the job placement success and challenges of graduate students in a higher education and student affairs professional preparation program at a mid-size public institution in the U.S. Specifically, this study investigated the impact of curricular standards in the form of supervised practice (i.e., internships and graduate assistantships on the job placement rate of recent alumni. In addition, perceived barriers in the job search process were investigated and examined comparatively by gender. Findings suggest that current curricular standards may not be sufficient for successful placement and that men and women do not differ significantly with respect to perceived barriers in their job search process. Implications for practice include a re-evaluation of curricular standards for student affairs professional preparation programs and a greater understanding of what factors and barriers contribute to successful graduate student placement.

    To examine understandings of global health issues among nursing students following participation in an international clinical placement during their pre-registration university education. Universities use international clinical placements, especially in developing countries, to develop cultural awareness in students; however, little is known about the longer term influences on students' understandings of global nursing. A retrospective cross-sectional design was used, using an exploratory, descriptive qualitative approach. Individual semi-structured interviews were conducted in 2014 with a purposive sample of 25 pre-registration nursing students from four Western Australian universities who undertook clinical placements across five countries. Data were analysed using inductive thematic analysis. Findings highlight that students developed new understandings around health systems including fragility of resource access, differences in clinical practice and variances in nursing roles between settings. Students also experienced challenges but were able to appreciate alternative world viewpoints. International clinical placements can develop greater awareness and help students form realistic strategies for using their nursing skills globally. Pre-placement training in cultural awareness and health system realities, along with strong supervisory support, is critical to success. © 2017 John Wiley & Sons Ltd.

    Full Text Available Joanne Porter, Julia Morphet, Karen Missen, Anita Raymond School of Nursing and Midwifery, Monash University, Churchill, VIC, Australia Aim: To measure final-year nursing students’ preparation for high-acuity placement with emphasis on clinical skill performance confidence. Background: Self-confidence has been reported as being a key component for effective clinical performance, and confident students are more likely to be more effective nurses. Clinical skill performance is reported to be the most influential source of self-confidence. Student preparation and skill acquisition are therefore important aspects in ensuring students have successful clinical placements, especially in areas of high acuity. Curriculum development should aim to assist students with their theoretical and clinical preparedness for the clinical environment. Method: A modified pretest/posttest survey design was used to measure the confidence of third-year undergraduate nursing students (n = 318 for placement into a high-acuity clinical setting. The survey comprised four questions related to clinical placement and prospect of participating in a cardiac arrest scenario, and confidence rating levels of skills related to practice in a high-acuity setting. Content and face validity were established by an expert panel (α = 0.90 and reliability was established by the pilot study in 2009. Comparisons were made between confidence levels at the beginning and end of semester. Results: Student confidence to perform individual clinical skills increased over the semester; however their feelings of preparedness for high-acuity clinical placement decreased over the same time period. Reported confidence levels improved with further exposure to clinical placement. Conclusion: There may be many external factors that influence students’ perceptions of confidence and preparedness for practice. Further research is recommended to identify causes of poor self-confidence in final-year nursing

    Clinical education programs in speech-language pathology enable the transition of students' knowledge and skills from the classroom to the workplace. Simulated clinical learning experiences provide an opportunity to address the competency development of novice students. This study reports on the validation of an assessment tool designed to evaluate speech-language pathology students' performance in a simulated clinical placement. The Assessment of Foundation Clinical Skills (AFCS) was designed to link to concepts and content of COMPASS(®): Competency Assessment in Speech Pathology, a validated assessment of performance in the workplace. It incorporates units and elements of competency relevant to the placement. The validity of the AFCS was statistically investigated using Rasch analysis. Participants were 18 clinical educators and 130 speech-language pathology students undertaking the placement. Preliminary results support the validity of the AFCS as an assessment of foundation clinical skills of students in this simulated clinical placement. All units of competency and the majority of elements were relevant and representative of these skills. The use of a visual analogue scale which included a pre-Novice level to rate students' performance on units of competency was supported. This research provides guidance for development of quality assessments of performance in simulated placements.

    English stakeholder collaboration has resulted in a new quality assurance process for non-medical health and social care placement providers and higher education institutions. This study aimed to discover the impact on student support that taking part in a pilot had on participating placement areas. Using a questionnaire survey with longitudinal follow-up one year later, we found that placement staff valued the opportunity to review and improve student support practices. This was still in evidence a year later where the pilot was described as giving the opportunity to provide evidence of aspects of student support practice; communicating and changing or developing aspects of that practice. Benefits accrued from interdisciplinary working in sharing and collaborating with other professions and organisations. Such activity could enhance clinical support staff activities and facilitate strategic partnerships between placement providers and higher education institutions.

    Knowledge of the effects on students of clinical educators' giving or withholding responsibility on placement is limited. The associated empowering, or disempowering impact indicates the need for research on what grounds such decisions are made. The study aimed to explore clinical educators' perspectives on the importance of giving student physiotherapists increasing levels of responsibility on clinical placement, and the factors considered when giving or withholding responsibility. A grounded theory methodology underpins this United Kingdom (UK) based study. The phase of the study reported in this article involved 26, semi-structured interviews with clinical educators, each followed by the completion of a diamond ranking exercise. Three themes emerged: 1) the ubiquity of risk; 2) the relationship between trust and trustworthiness; and 3) graduated supervision. The first theme, acknowledged that risk is ever-present and that clinical educators are used to managing it, balancing risk and responsibility given to students. The second theme highlighted the importance of developing trust/trustworthiness as a foundation for a sound working relationship between student and clinical educator. The third theme focusing on graduated supervision as a means of empowering students to take on increasingly demanding responsibilities on placement. The study illustrates the complex relationship between risk, trust, responsibility, and developing student autonomy. A strategy is proposed to provide an empowering alternative to the tendency to increase surveillance and/or limit the responsibility for students who lack confidence or capability in taking responsibility on clinical placement. Future research could aim to test the strategy more widely.

    Projected nursing shortfalls in Australia have identified the need for organisational planning and strategies around recruitment and retention in healthcare facilities. Strategies include but are not limited to alliances with university faculty and the quality of undergraduate clinical placement experience. This cross-sectional study explored undergraduate nursing students' satisfaction with clinical placement experience from the perspective of multiple university faculties, and the relationship this has with future employment intention at a metropolitan hospital in Sydney, New South Wales. Findings from respondents demonstrated satisfaction with the clinical placement on the following criteria: expectations being met; welcoming of unit staff and attitudes of thereafter; clinical and university facilitator support; and participation in patient care. Three quarters of respondents also indicated that they would consider the hospital as a future employer. Satisfaction with clinical placement experience may aid organisational recruitment strategies.

  12. Influence of the placement period on the development of professional identity for social education students

    2016-06-01

    Full Text Available The Social Education Degree placement for the National University for Distance Education (UNED allows students to experience and reflect upon the labour situation. Its influence on the development of the student professional identity is an important subject for both placement tutors and teachers. The study combines the search for and analysis of qualitative and quantitative data to assess the influence of the Professional Placement III course, the students’ first contact with the real business world, on the development of their professional identity. Throughout the research it has been possible to determine an emerging concept in the professional identity of students before the start of the placement, which changes and consolidates depending on their experience within the placement programme; these results are similar to those obtained in research relating to other professions similar to Social Education (Pontes, Ariza & Del Rey, 2010. Therefore, it can be stated that this course is an important variable that especially influences the development of the professional identities of future social educators.

  13. Clinical expectations: what facilitators expect from ESL students on clinical placement.

    San Miguel, Caroline; Rogan, Fran

    2012-03-01

    Many nursing students for whom English is a second language (ESL) face challenges related to communication on clinical placement and although clinical facilitators are not usually trained language assessors, they are often in a position of needing to assess ESL students' clinical language performance. Little is known, however, about the particular areas of clinical performance facilitators focus on when they are assessing ESL students. This paper discusses the results of a study of facilitators' written assessment comments about the clinical performance of a small group of ESL nursing students over a two and a half year period. These comments were documented on students' clinical assessment forms at the end of each placement. The results provide a more detailed insight into facilitators' expectations of students' language performance and the particular challenges faced by ESL students and indicate that facilitators have clear expectations of ESL students regarding communication, learning styles and professional demeanour. These findings may help both ESL students and their facilitators better prepare for clinical placement.

  14. A medical student's perspective of participation in an interprofessional education placement: an autoethnography.

    Gallé, Jennifer; Lingard, Lorelei

    2010-11-01

    Interprofessional education (IPE) has emerged as a critical pedagogy for promoting interprofessional collaboration (IPC) within healthcare. However, the literature includes few reports of students' perspectives on IPE experiences. Understanding students' experiences is critical, as they are the crux of IPE's culture change agenda. This paper presents an autoethnographic account of my experiences as a medical student participating in an IPE placement within a Canadian academic hospital. During the five-week placement, I collected data using participant observation and reflective journaling on all placement experiences. I expanded my notes using the emotional recall technique and conducted thematic analysis. Using a series of narrative vignettes, this paper explores the relationships between my personal experience and the cultural and educational issues underpinning IPE. The first vignette explores the relationship between students' patient access and our status in tutorial discussion. The second vignette considers the impact of shadowing on my appreciation of another professional's practice. The last vignette portrays my experience learning about the complex politics that shape IPC. The conclusion suggests that the IPE placements incorporate reflexive activities (i.e., journaling and interviewing) to enhance the students' appreciation and understanding of roles, responsibilities and professional perspectives, and to promote critical thinking and professional growth.

    2014-01-01

    Full Text Available Differences in student performance were analyzed for Black males in Connecticut, Florida, Maryland, Massachusetts, and Texas on the Advanced Placement English Language and Composition, Calculus AB, Biology, and United States History examinations from the 2001 through the 2012 exam years. All analyses included in the comparisons of overall examination scores and U.S. History examination scores were statistically significant. Of the 48 individual examination comparisons, 26 yielded evidence of a statistically significant difference among the Black male students from the selected states. Massachusetts was the state with the highest percentages of Black male students who achieved an AP score of 4 or 5. Conversely, Texas was the state with the highest percentages of Black male students who failed to achieve an AP score of 4 or 5. Implications for policy regarding advanced placement testing as an avenue for preparing students for college and recommendations for future research are discussed.

    2015-04-01

    The purpose of this study was to gain understanding of Norwegian students' experience of learning in clinical placement in Bangladesh without formal one-to-one supervision, by a personal mentor in the ward. Using focus group interviews with bachelor nursing students we explored the significance of 'communities of practice' in nursing practicum abroad, socialization and knowledge transfer. Seven third year bachelor nursing students enrolled in a clinical placement programme in Bangladesh participated in focus group interviews prior to their departure to Bangladesh, during their stay in Bangladesh and after their return to Norway. The Students' marginality and 'peripheral participation' triggered insight and reflection. The challenging but advantageous position of the peripheral students was heightened further due to the lack of one-to-one supervision in the clinic. Their previous experience with problem based learning and group learning was an asset that made them more resilient and helped them to cope.

    Quality clinical placement experiences have been associated with nurses' workplace social capital. Social capital is broadly understood as the social organisation of trust, norms and networks that benefit society. Building social capital in the workplace may benefit experiences of staff and students. The aim of this study was to assess the impact of building workplace social capital on student nurse perceptions of clinical learning experiences. A quality improvement process was measured through repeated student surveys. First, second, third year students (n = 1176) from three universities completed a validated Student Clinical Learning Culture Survey (SCLCS) following their placement, at the commencement of quality improvement initiatives and five years later. The SCLCS measured students' perceptions of social affiliation, their motivation, satisfaction and dissatisfaction with clinical contexts. The first year of systematic changes focused on increasing student numbers along with improving communication, trust and knowledge sharing, antecedents to workplace social capital. No change was evident after the first year. Six years after commencement of building workplace social capital differences across all subscales, except dissatisfaction, were significant (p social capital that enhances student placement experiences.

    Graduate nurses may have knowledge and adequate clinical psychomotor skills however they have been identified as lacking the clinical reasoning skills to deliver safe, effective care suggesting contemporary educational approaches do not always facilitate the development of nursing students' clinical reasoning. While nursing literature explicates the concept of clinical reasoning and develops models that demonstrate clinical reasoning, there is very little published about nursing students and clinical reasoning during clinical placements. Semi-structured interviews were conducted with ten clinical educators to gain an understanding of how they recognised, developed and appraised nursing students' clinical reasoning while on clinical placement. This study found variability in the clinical educators' conceptualisation, recognition, and facilitation of students' clinical reasoning. Although most of the clinical educators conceptualised clinical reasoning as a process those who did not demonstrated the greatest variability in the recognition and facilitation of students' clinical reasoning. The clinical educators in this study also described being unable to adequately appraise a student's clinical reasoning during clinical placement with the use of the current performance assessment tool.

    Aims and method Research shows that 16- to 19-year-olds express the greatest level of negative attitudes towards people with mental illness. Our aim was to assess the effectiveness of work experience placements in influencing secondary-school students' attitudes towards mental illness and career choices. The Adolescent Attitude Towards Mental Illness questionnaire measured and assessed the adolescents' attitude changes. Pre- and post-evaluation questionnaires assessed changes in their career choices. Results There was a statistically significant change in the adolescents' attitudes, especially regarding categorical thinking and perceptions that people with mental illness are violent and out of control. There was also a positive shift in their career choices towards options in the field of mental health. Clinical implications Work experience placements can have a positive impact on secondary-school students' attitudes towards mental illness and may improve the level of student recruitment into the field of psychiatry.

    2011-02-01

    Full Text Available Work Internship Placements (WIP is a new and transversal enterprise internships programme, which is focused on quality improvement, academic control and satisfaction of collaborating enterprises. This programme is addressed to the engineering students of the Polytechnic School at the University of Girona (UdG in Spain. The fundamental WIP infrastructure combines a web-based intranet platform, that provides a complete set of WIP tools, with a protocol of procedures and tasks that are observed and followed at all internship stages by every participating agent, i.e. enterprises, students, coaching professors and administrative staff. Our new programme is centered on a broader, more holistic internship placement procedure than the traditional “career and academic goals” approach. The WIP programme has been found to be a valuable asset in addressing enterprise and student needs in the experiential project.

Interprofessional clinical placements offer an opportunity for teamwork education, as students in various professions can work and learn together. In this sequential, mixed-method study, focus group and survey techniques were used to evaluate students' educational experiences after 2-week ward-based interprofessional clinical placements. Forty-five senior nursing, medicine, and other health care students cared for patients in hospital wards under professional supervision, with nursing-medicine student "teams" leading care. Thirty-six students attended nine exit focus groups. Five central themes that emerged about training were student autonomy and workload, understanding of other professional roles, communication and shared knowledge, interprofessional teamwork/collaboration, and the "inner circle", or being part of the unit team. The learning environment was described as positive. In a postplacement satisfaction survey (n=38, students likewise rated the educational experience highly. In practicing teamwork and collaboration, students were able to rehearse their future professional role. We suggest that interprofessional clinical placements be regarded as an essential learning experience for senior preprofessional students. More work is needed to fully understand the effect of this interactive program on students' clinical learning and preparation for practice

    Abstract Background: Little is known about which diversity characteristics if any, impact on nursing students' clinical placements or how these may affect the quality of their learning experiences. There is therefore a need to better understand these effects not only from the student's perspective but also from the perspective of the staff who supervise them, in order to ensure students obtain maximal benefit from their placements. Aim: To describe the clinical experiences of nursing students and the diversity characteristics that affect this learning experience. Methods: Data were collected from a series of open-ended questions embedded within a larger anonymous web-based survey, from August 2011 to March 2012. Participants included first, second and third year undergraduate Bachelor of Nursing students (N=704) and faculty members involved in the clinical learning environment (N = 165) from seven Australian universities. Findings: Qualitative findings were clustered into three main themes, differences, difficulty and discrimination, each with three subthemes. Conclusion: Findings suggest a need to offer appropriate support for nursing students who feel different because of diversity characteristics. Whilst some of the participant perceptions are confronting they provide valuable insights for universities developing curricula and the clinical placement facilities where students obtain their experience.

    For over 15 years the College of Nursing at the University of Saskatchewan has facilitated study abroad clinical placements in a number of countries to enhance student learning. Nursing students often find their study abroad experience to be a defining moment in their educational program, and in their personal and professional growth. The main objective of this research was to explore factors influencing nursing students' decisions to study abroad. A descriptive longitudinal design study was conducted using an online survey. The Study Abroad Survey was distributed to all undergraduate and graduate nursing students, in all years of all programs, at all sites of the College of Nursing, University of Saskatchewan in Saskatchewan, Canada. A total of 1058 nursing students registered in the 2013-2014 academic year were surveyed. The data were collected using an online survey administered by Campus Labs™ (2014). Students indicated that their interest in study abroad international experiences was high (84%), with many perceived benefits, but barriers to participation were also high for these students. Financial barriers topped the list (71%), followed by family responsibilities (30%) and job obligations (23%). The research highlights the factors behind student decision making related to international placements, and provides the basis for improvements to the College of Nursing's International Study Abroad Program (ISAP). Previous travel and international service learning, resulting in increased perceived value of a study abroad experience may prove to be the more significant factor influencing decision making, rather than financial barrier.

    Offering nursing students' international clinical placement during the educational program is one response to meet the need of cultural competence among nurses. This paper provides insight into the impact of clinical placement, in a developing country, on third year nursing students. In the study we investigated how short term international clinical placement impacted Norwegian nursing students' development of cultural competency. In this study we utilised a qualitative descriptive design and used individual interviews with eighteen Norwegian nursing students who had all participated in an international clinical placement. The data were analysed using the principles of systematic text condensation. In spite the international clinical placement only was four weeks, the findings suggested that real life experience culturally awakened the students and forced an ongoing process developing cultural competence. However, it is important to give students time to reflection. Although increased cultural awareness and a growing cultural competence was identified by the students undertaking international clinical placement, further research is required. It is important to investigate the best methods to support the students' reflection such that the experiences lead to learning. Copyright © 2017 Elsevier Ltd. All rights reserved.

    2004-09-01

    Full Text Available An exploratory study was conducted with the aim of discovering and describing experiences of psychiatric nursing students during clinical placement in a psychiatric unit. For the purpose of the study an unstructured interview was conducted with each participant during their first placement in a psychiatric unit to identify the factors experienced as stressful. The results indicated that all eight participants experienced average to high stress. Sources of stress identified included, among others, ineffective teaching and learning programmes, poor managerial governance of the service, detachment of professional nurses from their teaching role, poor relationships among staff, overreliance on the medical model of care and patient neglect. Psychiatric nursing students sampled indicated universal support for in-service education and training for professional nurses, attitude change of professional nurses towards students, support for student initiatives, student involvement in patient care and adequate allocation of resources for patient care and nurse training. The exploration and description of experiences of the psychiatric nursing students will help nurse educators plan clinical learning opportunities in such a way that they are less stressful, thus ensuring that psychiatric nursing students are equipped to utilise themselves as therapeutic instruments.

    Full Text Available Abstract Background Although Western models of education are being used to establish health professional programs in non-Western countries, little is known about how students in these countries perceive their learning experiences. The purpose of this qualitative study was to describe the reflections of physiotherapy students from a Middle East culture during their clinical placements and to compare them to reflections of physiotherapy students from a Western culture. Methods Subjects were six senior students (3 females, 3 males, mean age 22.6 years and 15 junior, female students (mean age 20.1 years in the baccalaureate physiotherapy program at a university in the United Arab Emirates (UAE. They wrote weekly entries in a journal while in their clinical placements. They described an event, their reaction to it, and how it might affect their future behavior. Two evaluators independently read and coded the content of all the journals, and then worked together to categorize the data and develop themes. A third evaluator, an UAE national, independently read the journals to validate the content analysis. A feedback session with students was used to further validate the data interpretation. The themes were compared to those derived from a similar study of Canadian physiotherapy students. Results The content of the students' reflections were grouped into 4 themes: professional behavior, awareness of learning, self-development and shift to a patient orientation, and identification and analysis of ethical issues. Although the events were different, students from the UAE considered many of the same issues reflected on by Canadian students. Conclusion Physiotherapy students from a Middle East culture consider many of the same issues as students from a Western culture when asked to reflect on their clinical experience. They reflect on their personal growth, on how they learn in a clinical setting, and on the ethical and professional behaviors of themselves

  20. The Advanced Placement Expansion of the 1990s:How Did Traditionally Underserved Students Fare?

    Directory of Open Access Journals (Sweden)

    Kristin Klopfenstein

    2004-12-01

    Full Text Available The College Board’s Advanced Placement (AP Program, which allows students to take college-level courses while in high school, enjoyed tremendous growth in the 1990s. Despite overall growth, small rural schools and high poverty schools continue to offer relatively few AP courses, and black, Hispanic, and low income students remain grossly underrepresented in AP classes. During the 1990s, AP incentive programs primarily subsidized test fees for low income students, but this provided no incentive for low income and rural schools to expand their AP course offerings and did nothing to strengthen the weak academic preparation of low income, black and Hispanic students. Recent federal funding changes provide a step in the right direction by supporting a comprehensive approach to increasing the AP access and participation of traditionally underserved students.

    United Kingdom (UK) health policy has adopted an increasing community and primary care focus over recent years (Department of Health, 1997; Department of Health, 1999. Making a Difference: Strengthening the Nursing, Midwifery and Health Visitor Contribution to Health and Health Care. Department of Health, London; Department of Health, 2004. The NHS Knowledge and Skills Framework (NHS KSF). Department of Health, London). Nursing practice, education and workforce planning are called upon to adapt accordingly (Department of Health, 2004. The NHS Knowledge and Skills Framework (NHS KSF). Department of Health, London; Kenyon, V., Smith, E., Hefty, L., Bell, M., Martaus, T., 1990. Clinical competencies for community health nursing. Public Health Nursing 7(1), 33-39; United Kingdom Central Council for Nursing, Midwifery and Health Visiting, 1986. Project 2000: A New Preparation for Practice. UKCC, London). Such changes have major implications for pre-registration nursing education, including its practice placement element. From an educational perspective, the need for increased community nursing capacity must be balanced with adequate support for student nurses' learning needs during community-based placements. This qualitative study explored six second year student nurses' experiences of 12 week community-based practice placements and the extent to which these placements were seen to meet their perceived learning needs. The data came from contemporaneous reflective diaries, completed by participants to reflect their 'lived experience' during their practice placements (Landeen, J., Byrne, Brown, B., 1995.

    Cultural awareness and cultural competence have been the focus of the transcultural nursing literature that has explored the roles and responsibilities of nurses in their care of Aboriginal and Torres Strait Islander Peoples. Cultural immersion programs, upholding cultural safety and cultural humility, offer valuable guidance to the education of nursing students regarding Aboriginal and Torres Strait Islander health and cultures. This study seeks to explore nursing students' experiences of a cultural immersion program within Aboriginal Medical Services (AMSs) in New South Wales, Australia. Eight nursing students participated in a mixed methods design exploratory study of their clinical placement within AMSs. A survey gathered data regarding levels of preparation and confidence, learning barriers, placement stressors and personal reflections. Nursing students reported positive and transformative experiences of intercultural learning. Cultural immersion programs provide a valuable framework for the design and evaluation of clinical placement programs for nursing students within intercultural learning spaces.

    2016-01-01

    This paper explores how the student placement experience may influence employment choices in the context of paediatric nursing. A qualitative research methodology was used. Data was collected using semi structured interviews at a tertiary teaching hospital. The sample group comprised of six newly qualified nurses who had completed their Bachelor of Nursing less than 12 months before the interview. They had completed at least one clinical placement at the site of data collection in their 2nd or 3rd year of undergraduate nursing studies. The main themes contributing to the student nurse experience within the context of paediatric nursing included the wish to work with children, a job being available, support during clinical placements and assistance with future career planning while on placement. The support experienced by student nurses during their clinical placement was seen to have a very positive influence on their future employment choices. Group de-briefing to support mutual understanding and sharing was seen to be a highly positive aspect of a clinical placement. Also how students were treated by clinical staff was a key factor that influenced future employment choices.

    Students are sometimes involved in incidents during clinical training. To the authors' knowledge, no quantitative studies of incidents specifically involving physiotherapy students on clinical placement are available in the literature. A retrospective audit (2008 to 2011) of incident reports involving physiotherapy students was conducted to identify the nature and features of incidents. The study aimed to determine if injuries to a student or patient were more or less likely when the supervisor was in close proximity, and whether students with lower academic performance in their preclinical semester were more likely to be involved in an incident. There were 19 care-delivery-related and three equipment-related incidents. There were no incidents of violent, aggressive or demeaning behaviour towards students. The incident rate was 9.0/100,000 student-hours for third-year students and 6.8/100,000 student-hours for fourth-year students. The majority of incidents (55%) occurred from 11 am to 12-noon and from 3 pm to 3.30 pm. Incidents more often resulted in patient or student injury when the supervisor was not in close proximity (approximately 50% vs approximately 20%), although the difference was not significant (P=0.336). The academic results of students involved in incidents were equivalent to the whole cohort in their preclinical semester {mean 75 [standard deviation (SD) 6] vs 76 (SD 7); P=0.488}. The unexpected temporal clustering of incidents warrants further investigation. Student fatigue may warrant attention as a potential contributor; however, contextual factors, such as staff workload, along with organisational systems, structures and procedures may be more relevant. The potential relationship between supervisor proximity and injury also warrants further exploration. The findings of the present study should be integrated into clinical education curricula and communicated to clinical educators. Copyright © 2014 Chartered Society of Physiotherapy. Published by

    The psychological and social sciences literature is replete with assertions that human beings are fundamentally and pervasively motivated by the need to belong. This paper reports on some of the findings from the qualitative phase of a mixed-method, multi-site study that explored nursing students' experience of belongingness while on clinical placements. Students from Australia and the United Kingdom were interviewed to identify factors that impact upon and are consequences of belongingness. A montage of participants' stories is used to illustrate some of the key features of clinical workplaces that are conducive to the development of belongingness. Contextual factors and interpersonal dynamics were seen to have a significant bearing on students' experiences. Clinical leaders/managers who were welcoming, accepting and supportive, and nursing staff who were inclusive and encouraging, facilitated students' perception of being valued and respected as members of the nursing team. Additionally, the provision of consistent, quality mentorship was identified as important to students' feelings of connectedness and fit. The experience of belongingness, in turn, enhanced students' potential for learning and influenced their future career decisions. Alternatively, alienation resulted from unreceptive and unwelcoming clinical environments and from the dissonance created when students' personal and professional values did not articulate with those evident in practice environments. Consequently, distress, detachment and disengagement occurred and students' capacity and motivation for learning was negatively impacted.

    Phenomenon: Peer assisted learning (PAL) is frequently employed and researched in preclinical medical education. Fewer studies have examined PAL in the clinical context: These have focused mainly on the accuracy of peer assessment and potential benefits to learner communication and teamwork skills. Research has also examined the positive and negative effects of formal, structured PAL activities in the clinical setting. Given the prevalence of PAL activities during preclinical years, and the unstructured nature of clinical placements, it is likely that nonformal PAL activities are also undertaken. How PAL happens formally and informally and why students find PAL useful in this clinical setting remain poorly understood.

  8. Stressed out or subjective acquisition of competence – how do veterinary students see their curative work placement?

    Full Text Available Veterinary studies in Germany are regulated by the Veterinary Certification Act (TAppV. The practical part of the education consists of 1,170 hours, whereby up to 850 hours can be spent on the curative work placement. A curative work placement can result in physical and psychological stress in the sense of a professional overload. It is the aim of this study to find out in what areas and to what extent competence is acquired and psychological stress exists in students during their work placement. Veterinary students (n=142 from all German education institutes participated in a voluntary online-study based on Burnout Screening Scales (BOSS as well as a questionnaire regarding the acquisition of competence and excessive stress during the work placement (FKÜP. The distribution of values for work placement related stress show that such work placement related stress is generally slightly increased (T=60 and lies above that of occupational stresses within the normal population. Work placement related physical complaints also show a significant slight increase (T=61. A value (T=42 within the normal range was determined for the resource values. Few of the students questioned considered themselves to be excessively stressed in favour of a high subjective acquisition of competences. The largest increase regarding the acquisition of competence was noted for the areas of animal handling/restraint and application and injection techniques. In the sense of a perceived excessive demand regarding practical capabilities the areas of emergency management, surgery and medication dispensation were mentioned. With regard to the load structure and the acquisition of competence by veterinary students during their work placement, more support of the individual and a balancing of teaching/learning goals would be desirable and represents a promising approach.

    2014-06-01

    Full Text Available This paper discusses research findings into a study of UK student learning on international social work placements in Malaysia in collaboration with two Malaysian universities: Universiti Sains Malaysia and Universiti Malaysia Sarawak. The discussion focuses on those placements taking place in children’s services: residential care and community-based support programmes. The aim of the study was to explore how social work students adapt to unfamiliar learning situations in new cultural contexts with the goal of increasing cultural competence. Data were drawn from formal but anonymised student learning exercises as a non-assessed requirement of this particular placement. Findings indicated a wide range of responses towards social work practice with vulnerable children in the Malaysian context in terms of student constructions of care and abuse. Subject to an analytical schema, the collision or adaptation of otherwise normative professional and personal values are examined in detail.

To determine the level of difficulty in learning interventions, depending on which week of rotation in clinical placement the student is. Qualitative study using Delphi consensus technique, involving nurses with teaching experience who work in hospital surgical units, where students undertake the Practicum. The results were triangulated through a questionnaire to tutors about the degree of conformity. A consensus was reached about the interventions that students can achieve in surgical units and the frequency in which they can be performed. The level of difficulty of each intervention, and the amount of weeks of practice that students need to reach the expected level of competence was also determined. The results should enable us to design better rotations matched to student needs. Knowing the frequency of each intervention that is performed in each unit determines the chances of learning it, as well as the indicators for its assessment. Copyright © 2015 Elsevier España, S.L.U.

    2015-09-01

    Despite the fact that high quality clinical placement is an integral component of pre-registration nursing education for the development of the future nursing workforce, the literature identifies an ongoing struggle to 'get it right'. To examine qualitative data gathered through the Quality Clinical Placements Evaluation project to identify what pre-registration nursing students deemed helpful and not helpful influences on their first year Professional Experience Placement. A total of 553 first year undergraduate nursing students from 2010 to 2012 were enrolled in the programme and all were invited to complete a validated survey to measure the quality of their first clinical placement. A total of 361 completed surveys were returned. This paper examines the data provided through open-ended questions within the survey related to most helpful and least helpful aspects of their clinical experience. An inductive analysis approach using NVIVO allowed inherent areas to emerge from the raw data forming three key themes that influenced the experience of students. Feeling welcomed, individual versus team attitudes, and student expectations of supervising ward nurses were the themes identified that were perceived by the student as important to the success of learning and the quality of the experience overall. The findings echo previous research into the student experience of clinical placement; however the focus regarding the need for students to have a quality relationship with the supervising nurse is an area that warrants further exploration. Furthermore, we argue that students should be purposely engaged in the tertiary sector and provided guidance and strategies related to forming and maintaining relationships with those that supervise their clinical placement, in order to ensure consistent positive experiences. The outcomes from this study suggest that a missing component is teaching undergraduates how to manage relationships in clinical settings. Copyright © 2015

    An increased burden of chronic and complex conditions treated in the community and an aging population have exacerbated the primary care workload. Predicted nursing shortages will place further stressors on this workforce. High quality clinical placements may provide a strategic pathway to introduce and recruit new nurses to this speciality. This paper is Part 2 of a two part series reporting the findings of a mixed methods project. Part 1 reported on the qualitative study and Part 2 reports on the quantitative study. Forty-five pre-registration nursing students from a single Australian tertiary institution and 22 primary care Registered Nurse (RN) mentors who supervised student learning completed an online survey. Students largely regarded their primary care placement positively and felt this to be an appropriate learning opportunity. Most RNs were satisfied with mentoring pre-registration nursing students in their setting. Furthermore, the RNs desire to mentor students and the support of general practitioners (GPs) and consumers were seen as key enablers of pre-registration nursing placements. Findings from this study provide a preliminary impression of primary care clinical placements from the perspective of pre-registration nursing students and registered nurse mentors. Further research should examine whether a broader scope of non-traditional health settings such as non-government organisations, charities, pharmacies, welfare and social services can also provide appropriate learning environments for pre-registration nursing students.

    Bullying in health workplaces has a negative impact on nurses, their families, multidisciplinary teams, patient care and the profession. This paper compares the experiences of Australian and UK baccalaureate nursing students in relation to bullying and harassment during clinical placement. A secondary analysis was conducted on two primary cross-sectional studies of bullying experiences of Australian and UK nursing students. Data were collected using the Student Experience of Bullying during Clinical Placement (SEBDCP) questionnaire and analysed using descriptive and inferential statistics. The total sample was 833 Australian and 561 UK students. Australian nursing students experienced a higher rate of bullying (50.1%) than UK students (35.5%). Students identified other nurses as the main perpetrators (Aust 53%, UK 68%), although patients were the main source of physical acts of bullying. Few bullied students chose to report the episode/s. The main reason for non-reporting was fear of being victimised. Sadly, some students felt bullying and harassment was 'part of the job'. A culture of bullying in nursing persists internationally. Nursing students are vulnerable and can question their future in the 'caring' profession of nursing after experiencing and/or witnessing bullying during clinical placement. Bullying requires a zero tolerance approach. Education providers must develop clearer policies and implement procedures to protect students - the future nursing workforce.

    2017-10-01

    Student confidence is an important contributor to a successful professional placement experience. The present study aimed to evaluate a placement preparation program for student dietitians and to assess the impact on self-rated confidence with respect to commencing placements. The present study is part of a design-based research approach that involves students in a cyclic enquiry to evaluate and improve curricula. Nutrition and Dietetics students at an Australian university participated in a 1-week mandatory workshop - Pre-Placement week (PrePW), N = 98 students: in 2015 (n = 54) and 2016 (n = 44). An online survey was conducted before and after PrePW using a five-point Likert scale (1 = not confident; 5 = very confident) to assess self-rated confidence to commence placements. Mean (SD) scores were calculated. Paired and independent t-tests evaluated within- and between-group differences, respectively. Before PrePW, the mean (SD) for student confidence to commence placements overall (in all areas of practise) was 'somewhat confident' [2.9 (0.6) in 2015 and 3.0 (0.7) in 2016]. Students were least confident to commence Clinical Practice [2015: 2.5 (0.6); 2016: 2.8 (0.6)] compared to Food Service Management (FSM) [2015: 3.2 (0.9); 2016: 3.1 (0.9)] and Community and Public Health Nutrition (CPHN) [2015: 3.3 (0.9); 2016: 3.2 (0.8)]. Student feedback from PrePW 2015 was used to change the curriculum and PrePW program. The 2016 students reported significantly greater confidence within all areas of practice: Clinical Practice [3.4 (0.6)], FSM [3.7 (0.6)] and CPHN [3.8 (0.6)], including confidence to commence placements overall [3.6 (0.6)] (P confidence in preparation for professional placement. © 2017 Commonwealth of Australia.

    While it is commonly accepted that nursing care is generally of a good standard, it would be naïve to think that this is always the case. Over recent years, concern about aspects of the quality of some nursing care has grown. In tandem with this, there is recognition that nurses do not always report poor practice. As future registrants, student nurses have a role to play in changing this culture. We know, however, relatively little about the factors that influence student decisions on whether or not to report. In the absence of a more nuanced understanding of this issue, we run the risk of assuming students will speak out simply because we say they should. To explore influences on student decisions about whether or not to report poor clinical practice, which is a result of deliberate action and which is witnessed while on placement. Qualitative interviews were conducted with thirteen pre-registration nursing students from the UK. Participants included both adult and mental health nurses with an age range from 20 to 47. Data were analysed to identify key themes. Category integrity and fit with data were confirmed by a team member following initial analysis. Four themes. The first of these, 'I had no choice' described the personal and ethical drivers which influenced students to report. 'Consequences for self' and 'Living with ambiguity' provide an account of why some students struggle to report, while 'Being prepared' summarised arguments both for and against reporting concerns. While there is a drive to promote openness in health care settings and an expectation that staff will raise concerns the reality is that the decision to do this can be very difficult. This is the case for some student nurses. Our results suggest ways in which educationalists might intervene to support students who witness poor practice to report. Copyright © 2015 Elsevier Ltd.

    Paliadelis, Penny; Wood, Pamela

    2016-09-01

    This paper reports on the learning potential of a reflective activity undertaken by final year nursing students, in which they were asked to recount two meaningful events that occurred during their clinical placements over the duration of their 3-year nursing degree program and reflect on how these events contributed to their learning to become beginning level Registered Nurses (RNs). This descriptive qualitative study gathered narratives from 92 students as individual postings in an online forum created within the University's learning management system. An analysis of the students' reflections are the focus of this paper particularly in relation to the value of reflecting on the identified events. Four themes emerged that clearly highlight the way in which these students interpreted and learned from both positive and negative clinical experiences, their strong desire to fit into their new role and their ability to re-imagine how they might respond to clinical events when they become Registered Nurses. The findings of this study may contribute to developing nursing curricula that better prepares final year students for the realities of practice.

    Health-care organizations have a key role in improving the quality of student mentorship in placements. This study presents the findings of Finnish and British mentors' conceptions of how to build organizational capacity for the provision of effective mentorship for pre-registration nursing students during placement learning. The data obtained from nine semistructured focus group interviews were analyzed using a phenomenographic approach. Three categories of description are presented. Organizations were mainly perceived as optimizers of investments in developing clear strategies for the provision of sufficient resources and professional support for mentors. The creation of a positive mentorship culture within a development-oriented, student-centred and goal-directive atmosphere was seen as essential. Furthermore, providing well-prepared placements for clinical practice of students was emerged as crucial, which included adequate working conditions and stakeholders as well as arrangements of learning opportunities. It is concluded that effective student mentorship requires health-care organizations to invest in financial and human resources in order to promote the quality of the placement learning environments. Such provision will enhance students' recruitment, retention and effectiveness, leading to safe practice and cost-benefits for health-care organizations in the longer term. © 2011 Blackwell Publishing Asia Pty Ltd.

    2015-09-01

    Although the drive to engage service users in service delivery, research and education has mainstream acceptance, it is not easy to achieve meaningful involvement. The contribution that could potentially be made by users whilst accessing services is often overlooked. This study involved stakeholders (mentors, service users and a lecturer) working together to design, evaluate and refine a system enabling students to seek feedback from service users. The feedback concerned mental health students' interpersonal skills and occurred whilst on practice placement. This research aimed to explore the experiences of those concerned when nine students attempted to learn from rather than about service users. A 2-year study, encompassing five cycles of participatory action research (PAR). A small island community in the British Isles, adopting UK standards for pre-registration nurse education. Data came from interviews with service users and mentors and a series of reflective group discussions with students who volunteered to try out the feedback mechanism. The deliberations of the PAR stakeholder group informed the research cycles and added to the data, which were subject to thematic analysis. Findings indicated that service users volunteering to give feedback had unanimously positive experiences. Students' experience lay on a continuum: those with a stronger sense of self were more willing and able to ask for feedback than less confident students. Cultural adjustment to the role change needed was challenging, requiring self-awareness and courage. Over time, all students achieved deep learning and, for some, learning appeared transformative. Although contextual, the study concluded that the feedback initiative encouraged the development of more equitable relationships, in which mental health nurses respected the expertise of service users. This potentially benefits student development, recovery-orientated practice, service users and HEIs searching for meaningful ways to

    This study evaluated physiotherapy students' perception of a reflective journal in developing reflective thinking and practice and identified the main concepts recorded by students in the journal. A mixed methods study with qualitative content analysis of student journals and quantitative analysis of questionnaire responses. 131 (74 female, 57 male) physiotherapy students undergoing their first clinical placement. On completion of their placement, students submitted a reflective journal electronically and completed a questionnaire of closed and open ended questions. Questionnaires were analysed using frequencies for the responses of the closed questions and thematic analysis of the open ended questions. Journals were de-indentified and underwent a content analysis using Leximancer software to obtain a concept map and frequencies of the main concepts identified in the journals, with specific examples. The majority (88%, 79/90) of respondents found the journal useful in assisting them to learn from their experiences, and to develop reflective thinking and practice. 54% (49/90) indicated they would continue to use the journals. The most frequently identified concepts were residents, time and exercises; representing more than 5000 of the total concepts identified in the journals. Analysis of the reflective journals indicated that students demonstrated improvements in the three stages of reflective practice: awareness of thoughts and feelings, critical analysis of situation, and development of new perspectives. Guided journal writing may be a useful tool in facilitating reflective thinking and practice during clinical placements of physiotherapy students. Copyright © 2012 Chartered Society of Physiotherapy.

  15. Factors influencing choice of site for rural clinical placements by final year medical students in a South African university

    Directory of Open Access Journals (Sweden)

    Nontsikelelo O. Mapukata

    2017-01-01

    Full Text Available Background: Most of South Africa’s citizens who live in rural or underserved communities rely on the public health care sector to access quality health care. The value of rural exposure through clinical placements is well documented. Medical schools in South Africa have a responsibility to provide solutions that address the prevailing human resources challenges. Despite this commitment, medical students do not necessarily appreciate their role in resolving South Africa’s human resources challenges. This study aimed to assess the factors that influenced the choice of clinical learning sites in a self-selection process undertaken by Wits final year medical students for the compulsory 6-week integrated primary care block rotation.Methods: Qualitative data related to reasons for choice of service learning site were gathered from 524 pre-placement questionnaires completed by final year medical students entering the rotation over a 3-year period (2012–2014. Thematic analysis was performed using the MAXQDA software.Results: Eight themes emerged from the study indicating that the majority of participants were in favour of local urban underserved placement. Contextual factors, such as work commitments or family responsibilities, being compromised socially and losing academic standing were the main reasons for seeking urban placement. Good supervision, opportunistic learning, skills development and moral support were reasons for seeking rural placements. Previous voluntary exposure to rural practice or being of rural origin was a strong indicator for uptake of rural placement.Conclusion: This study has demonstrated the challenges faced by coordinators in balancing personal and institutional needs with country needs and the contextual factors that must be considered when implementing medical education programmes that respond to social challenges.

    2005-07-01

    This paper explores access to learning resources for nursing students when on placement. It also examines, in parallel, the impact of the move to enquiry based learning has on learning resources use by nursing students. The increased time spent learning in the clinical setting means that a deeper understanding of the use of learning resources by nursing students is necessary. A questionnaire survey was completed by 247 nursing students at Northumbria University around their use of learning resources on placement. This corresponded with focus groups being run with University and NHS providers of learning resources to establish the impact of enquiry based learning. It was found that effective collaboration between different stakeholders was especially important. Nursing students are also becoming increasingly sophisticated in their use of electronic learning resources. The nature of support for effective learning resources use by nursing students whilst on placement in the NHS has also been identified as key. The work has shown that it is very difficult to establish the impact of enquiry based learning on learning resources, as there are so many other variables.

    This article discusses the findings from a pilot study using short message service (SMS) texting to provide an additional means of support for health care students in practice placements. Pre-registration students were recruited students from 2nd year cohorts in Adult Nursing, Children's Nursing, Occupational Therapy, and Radiography to pilot the use of SMS texting with their private mobile phones from their work-based learning placements. The pilot was evaluated using an online questionnaire for students with follow-up telephone interviews, and face-to-face interviews with the four tutors. Data on the use of the service by students was also collated. Although the students made less use of the service than was anticipated, both staff and students were positive about the potential of this type of communication in providing an additional form of support for students in placements.

    To explore demographic differences in awarded marks of the final clinical placement in a physiotherapy undergraduate programme. Retrospective analysis of clinical placement assessment marks. A London university offering clinical placements throughout South East England. 333 physiotherapy students entering physiotherapy training between 2005 to 2009. Marks awarded following assessment using a clinical placement assessment form. The mean mark (SD) for age were standard entry 71 (7.4) vs. mature entry 72 (7.99) (ns); for gender male 72 (8.45) vs. female 71 (7.21) (ns); and ethnicity White British 72 (7.71) vs. ethnic minority 70 (7.01) (p=0.023). No interaction effects were observed between the independent variables and only ethnicity demonstrated a statistically significant effect (mean difference (MD) 2.4% 95%CI 0.5 to 4.3, F=5.24, p=0.023). This difference was maintained in most subcategories. Significant differences were observed for the interpersonal section (MD 2.21% 95%CI 0.14 to 4.28, F=4.409, p=0.03), the clinical reasoning section (MD 2.39% 95%CI 0.53 to 4.25, F=6.37, p=0.012) and the treatment section (MD 2.93 95%CI 1.10 to 4.83, F=9.198, p=0.003). Physiotherapy students from minority ethnic backgrounds were awarded a significantly lower mark than their white majority peers in final clinical placements, although the difference was small. Potential reasons are considered, with the strongest recommendation being for further enquiry into the potential relationship between ethnicity and success in undergraduate physiotherapy education.

The Rural and Private Midwifery Education Project (RPMEP) is a strategic government funded initiative to (1) grow the midwifery workforce within private midwifery practice and rural midwifery, by (2) better preparing new graduates to work in private midwifery and rural continuity of care models. this study evaluated midwifery students׳ experience of an innovative continuity of care clinical placement model in partnership with private midwifery practice and rural midwifery group practices. a descriptive cohort design was used. All students in the RPMEP were invited to complete an online survey about their experiences of clinical placement within midwifery continuity models of care. Responses were analysed using descriptive statistics. Correlations between total scale scores were examined. Open-ended responses were analysed using content analysis. Internal reliability of the scales was assessed using Cronbach׳s alpha. sixteen out of 17 completed surveys were received (94% response rate). Scales included in the survey demonstrated good internal reliability. The majority of students felt inspired by caseload approaches to care, expressed overall satisfaction with the mentoring received and reported a positive learning environment at their placement site. Some students reported stress related to course expectations and demands in the clinical environment (e.g. skill acquisition and hours required for continuity of care). There were significant correlations between scales on perceptions of caseload care and learning culture (r=.87 pflexible academic programme enabled students to access learning at any time and prioritise continuity of care experiences.

    Clinical skill development is essential to nurse education. Clinical skills are frequently taught in higher education institutions using clinical simulation. It is unclear if clinical skills are subsequently consolidated and developed in clinical placements. The aim of this survey was to evaluate pre-registration student nurses perceptions of the frequency of opportunities to practise, the level of supervision and assessment of, clinical skills in their clinical placements. This was a cross-sectional survey design using an online, self-report questionnaire including a Likert-type scale and open ended comments. Four hundred and twenty one students, from all year groups, from a university in the south of England on a wide variety of clinical placements participated. Participants evaluated the frequency of opportunity to practise, level of supervision and assessment of and feedback on performance of specific clinical skills. Clinical skills evaluated were measurement of vital signs, aseptic non-touch technique, assisting with eating and drinking, and assisting with comfort and hygiene. Data were analysed utilising Statistical Package for the Social Sciences Version 19. The frequency of opportunities to practise skills in clinical placement was variable with some participants reporting that they never had opportunity to practise essential skills. Similarly the level of supervision and assessment was also inconsistent suggesting that participants frequently practised clinical skills unsupervised without being assessed as competent. Inconsistencies in clinical skill development may lead to graduates who are not work ready and as a result, insufficient clinical competence potentially leads to unsafe practice and poor patient care. This calls for stronger partnerships between educators and clinical areas and the prioritisation of mentor preparation and education as well as organisational support in terms of mentor workload planning.

    Ethnic minority groups have been shown to obtain poorer final year degree outcomes than their majority group counterparts in countries including the United States, the United Kingdom and The Netherlands. Obtaining a lower degree classification may limit future employment prospects of graduates as well as opportunities for higher level study. To further investigate this achievement gap, we analyzed performance levels across three academic years of study of 3,051 Black, Asian and White students from a United Kingdom University. Analyses of covariance investigated effects of ethnicity and work placement experience (internships) on first, second and final year marks, whilst statistically controlling for a number of factors thought to influence achievement, including prior academic performance. Results demonstrated superior achievement of White students consistently across all years of study. Placement experience reduced, but did not eliminate, the size of the achievement gap exhibited by final year students. Sex, parental education and socioeconomic status had no significant main effects. Female students showed a more complex pattern of results than males, with Black females not showing the same final year uplift in marks as their Asian and White counterparts. Implications and possible explanations are discussed.

    Uganda has an acute problem of inadequate human resources partly due to health professionals' unwillingness to work in a rural environment. One strategy to address this problem is to arrange health professional training in rural environments through community placements. Makerere University College of Health Sciences changed training of medical students from the traditional curriculum to a problem-based learning (PBL) curriculum in 2003. This curriculum is based on the SPICES model (student-centered, problem-based, integrated, community-based and services oriented). During their first academic year, students undergo orientation on key areas of community-based education, after which they are sent in interdisciplinary teams for community placements. The objective was to assess first year students' perceptions on experiential training through community placements and factors that might influence their willingness to work in rural health facilities after completion of their training. The survey was conducted among 107 newly admitted first year students on the medical, nursing, pharmacy and medical radiography program students, using in-depth interview and open-ended self-administered questionnaires on their first day at the college, from October 28-30, 2008. Data was collected on socio-demographic characteristics, motivation for choosing a medical career, prior exposure to rural health facilities, willingness to have part of their training in rural areas and factors that would influence the decision to work in rural areas. Over 75% completed their high school from urban areas. The majority had minimal exposure to rural health facilities, yet this is where most of them will eventually have to work. Over 75% of the newly admitted students were willing to have their training from a rural area. Perceived factors that might influence retention in rural areas include the local context of work environment, support from family and friends, availability of continuing

    In-depth interviews of students with qualitative analysis of the responses were used to explore perceptions of the non-academic advantages and disadvantages of Advanced Placement (AP) and International Baccalaureate (IB) program participation, and differences between the AP and IB programs in those perceptions. Results revealed that benefits of participation, including pride in completing more challenging work, similarity and special bonds among participants, better treatment (more respect and responsibility) from teachers, better overall class atmosphere, and preference for AP and IB courses were consistent across schools and between programs. Also consistent were the disadvantages students reported, with marked differences in the intensity of disadvantages between the AP and IB programs. Specifically, as the amount of time students spent in homogeneously grouped settings increased, so did the workload, the intensity of the perceived social/emotional disadvantages of the workload, the perceived range of negative feelings between participants and non-participants, and the perceived negativity of participant strereotypes.

    2016-01-01

    Objectives The objective of this pilot study was to identify the type of workplace violence experienced by undergraduate paramedic and midwifery students. Methods The study used a cross-sectional methodology with the self-administered paper-based Paramedic Workplace Violence Exposure Questionnaire to elicit undergraduate paramedic and midwife responses to workplace violence whilst on clinical placements. There were 393 students eligible for inclusion in the study. A convenience sample was used. The anonymous questionnaire took 10 to 20 minutes to complete. Descriptive statistics are used to summarise the data with a two-tailed t-test used to compare groups. Results The main form of workplace violence was verbal abuse 18% and intimidation 17%. There was a statistically significant difference between midwifery and paramedic students for intimidation (t(134)=-3.143, CI: -0.367 to -0.082, p=0.002) and between females and males for sexual harassment (t(134)=2.029, CI: 0.001 to 0.074, p=0.045), all other results were not statistically different. Conclusions This pilot study is the first of its kind in Australia and internationally to identify exposure rates of workplace violence by undergraduate paramedic students during clinical placements and one of very few to identify midwifery students’ exposure rates of workplace violence. The study identified that students were exposed to a range of workplace violence acts from verbal abuse through to sexual harassment. These findings highlight a need for investigation of workplace violence exposure of medical, nursing and allied health students during the clinical phase of their studies. PMID:27941182

    Standley, Henrietta J

    2015-10-01

    Internationalization has commanded an ever-more prominent position in higher education over recent years, and is now firmly entrenched. While academia has long been outward looking-international research collaborations, conferences and student exchanges are well-established practices-it is relatively recently that internationalization has become a goal in its own right, rather than a consequence of normal academic activity. There are multiple interdependent drivers behind this: a focus on graduate employability and development of broad competencies and transferable skills in addition to subject-specific training, 'international awareness' being confirmed as a graduate attribute that is highly valued by employers, the availability of detailed information enabling prospective students to choose between Higher Education Institutions on the basis of their international opportunities and graduate employment rates, increasing competition between Institutions to attract the best students and to ascend national and international league tables, and (both driving and reflecting these trends) national policy frameworks. This minireview focuses on two aspects of internationalization of direct relevance to microbiology students and academic staff in a typical Higher Education Institution: student research placements overseas, and the impact of international mobility on teaching practice and the student experience. Practical strategies for developing intercultural awareness and enhancing employability are highlighted.

  6. An analysis of the impact of three high school schedules on student achievement in advanced placement biology classes

    Science.gov (United States)

    Arons-Polan, Bonnie

    This study examined the effect of three schedule types on student achievement in Advanced Placement Biology classes. AP Biology test scores from students on three types of full-year schedules were analyzed to assess the impact schedule type had on student achievement. The three schedules included the block and traditional schedules, and the rotating/hybrid, a blend of the former two schedules. The results indicated the variable most closely associated with success on the AP Biology exam was the length of experience the teachers had teaching the course, regardless of schedule type. Although significant differences were seen in mean AP Biology test scores among the three schedule types, this could be explained by the relationship between instructors' experience and schedule type. Regression analysis determined the two strongest predictors of successful performance on the AP Biology exam were instructors' experience and perceived teaching style, regardless of schedule type. It appears that the economically developed suburbs, had teachers with the largest amount of experience teaching AP Biology, and these teachers reported using a direct approach to teaching, using lecture greater than 50% of the time. The results of this study also suggest when restructuring to improve student achievement, educators should examine other variables in addition to the high school schedule. Restructuring the day to allow for longer classes must be accompanied by professional staff development to allow teachers to develop new teaching methods. Most of the teachers in the survey reported using lecture a great deal of the time, regardless of schedule type. Comments from the teachers from the various schedules revealed that the ability to add student centered, inquiry based activities and labs were dependent on adequate class time. No information on whether or not the teachers were given professional development to expand their repertoire of teaching methods when the school adopted a block

  14. African American Advanced Placement chemistry students and their developing study habits: A phenomenologically-based interpretive study

    Science.gov (United States)

    Rasmussen, Natalie D.

    The academic achievement gap between African American and White students has gained much attention in recent years. Much has been written about the causes of and reasons for this problem ranging from the vestigial effects of slavery to poor parenting. Much less has been written or understood about its solution. While it is impossible for educators to change the pasts of their African American students, it is possible to effect change for the few minutes in which they are in direct contact with them each day. If African American science students are taught effective study skills and habits, then perhaps they might have the tools to close the achievement gap themselves. The participants in this phenomenologically based interpretive study were five African American Advanced Placement Chemistry students from an inner-city high school. Three in-depth interviews were conducted with each of the participants during the beginning, middle and end of a semester. The purpose of the interviews was to locate the students in terms of their thought processes, experiences and perceived barriers concerning the nature and practice of effective study and retention of chemistry content. The interviews were recorded and transcribed. The texts were then analyzed for common themes. Five common themes emerged from the interviews. These were: (1) Homework vs. Study: a distinction between homework---which students knew how to approach; and study---which they did not. (2) Student Effort: their changing perception of adequate and effective study practices while in a rigorous course. (3) Teacher Rigor: they perceived high expectations and challenging work as a sign of respect from their teachers. (4) Parental Involvement: students' admission that they desired more input from parents regarding their academic performance. (5) Racial Considerations: their need to disprove negative stereotypes and their personal observations regarding racial differences in studying. A discussion of the themes and

    Students who demonstrate quiet incivility can be challenging and disrupt the learning that takes place in the community setting. Recognising incivility and acting to address this behaviour with students is difficult because the behaviour is not overt or obvious to others. The most important component in attempting to manage incivility is exploring the behaviour with the student to identify the potential cause, and negotiate a strategy to improve it. It is acknowledged that the behaviour may be due to personal, academic, or professional issues. If issues are not addressed, care activity and learning are affected, and this can result in failure to achieve in practice.

  16. Assessing students' English language proficiency during clinical placement: A qualitative evaluation of a language framework.

    Science.gov (United States)

    San Miguel, Caroline; Rogan, Fran

    2015-06-01

    The increase in nursing students for whom English is an additional language requires clinical facilitators to assess students' performance regarding clinical skills, nursing communication and English language. However, assessing language proficiency is a complex process that is often conflated with cultural norms and clinical skills, and facilitators may lack confidence in assessing English language. This paper discusses an evaluation of a set of guidelines developed in a large metropolitan Australian university to help clinical facilitators make decisions about students' English language proficiency. The study found that the guidelines were useful in helping facilitators assess English language. However, strategies to address identified language problems needed to be incorporated to enable the guidelines to also be used as a teaching tool. The study concludes that to be effective, such guidelines need embedding within a systematic approach that identifies and responds to students who may be underperforming due to a low level of English language proficiency.

    Full Text Available The present note arises from the author's talk at the conference ``Ischia Group Theory 2014''. For subgroups FleN of a group G denote by Lat(F,N the set of all subgroups of N , containing F . Let D be a subgroup of G . In this note we study the lattice LL=Lat(D,G and the lattice LL ′ of subgroups of G , normalized by D . We say that LL satisfies sandwich classification theorem if LL splits into a disjoint union of sandwiches Lat(F,N G (F over all subgroups F such that the normal closure of D in F coincides with F . Here N G (F denotes the normalizer of F in G . A similar notion of sandwich classification is introduced for the lattice LL ′ . If D is perfect, i.,e. coincides with its commutator subgroup, then it turns out that sandwich classification theorem for LL and LL ′ are equivalent. We also show how to find basic subroup F of sandwiches for LL ′ and review sandwich classification theorems in algebraic groups over rings.

  18. VLSI placement

    Energy Technology Data Exchange (ETDEWEB)

    Hojat, S.

    1986-01-01

    The placement problem of assigning modules to module sites in a regular array must be addressed in VLSI and WSI. The placement problem of assigning heterogeneous modules to module sites in a regular array is NP-complete. The placement problem could be simplified if one could find a footprint with the property that all modules of the optimum placement occupy locations in the footprint, with no vacancies within the footprint region. If such footprints were known, they could be precomputed for each system size and the optimization problem would be reduced to a search of placements meeting the footprint constraint. The author shows that the placement problem could not be simplified by finding footprints. As result, several heuristic algorithms for the placement problem were developed and compared to each other and other established algorithms with respect to time complexity and performance measured, by the expected distance traversed by an intermodule message. Compared to previous algorithms, one new heuristic algorithm gave better performance in a shorter execution time on all test examples.

    Full Text Available This project work addresses the crucial need to encourage undergraduate civil and environmental engineering students to gain employment skills and training right from the start of their studies so that their overall employability increases; their confidence level in networking with industry and within the workplace increases; and so that they are successfully able to obtain employment after finishing their studies. This initiative is a stepping-stone employability exercise which focuses specifically on first year students to help them engage with industry right from the start of their course. It is proposed that they would gain some realistic work experience both individually and as part of group within a virtual work environment using an action learning approach. The virtual environment used was based on SecondLife, a popular virtual reality programme. A pilot scheme was set up and run at Brunel University during the summer of 2014 using eight self-selecting first year students. The scheme’s outputs were extensively monitored and evaluated to assess its impact on the development of employability skills. This approach may prove a cost effective way of letting students gain an insight into the workplace whilst improving these skills. It may also prove a way for employers to select from a large range of students the best to actually undertake their real work-based internships.

  20. How Two Small Pharmacy Schools’ Competency Standards Compare with an International Competency Framework and How Well These Schools Prepare Students for International Placements

    Directory of Open Access Journals (Sweden)

    John Hawboldt

    2017-03-01

    Full Text Available International standards of pharmacy curricula are necessary to ensure student readiness for international placements. This paper explores whether curricula from two pharmacy programs, in Australia and Canada, are congruent with international standards and if students feel prepared for international placements. Nationally prescribed educational standards for the two schools were compared to each other and then against the International Pharmaceutical Federation (FIP Global Competency Framework. Written student reflections complemented this analysis. Mapping results suggested substantial agreement between the FIP framework and Australia and Canada, with two gaps being identified. Moreover, the students felt their programs prepared them for their international placements. Despite differences in countries, pharmacy programs, and health-systems all students acclimatized to their new practice sites. Implications are that if pharmacy programs align well with FIP, pharmacists should be able to integrate and practise in other jurisdictions that also align with the FIP. This has implications for the mobility of pharmacy practitioners to countries not of their origin of training.

  1. HYBRID-SANDWICHED REINFORCEMENT WITH GEOSYNTHETICS

    Yasuhara, Kazuya; Yamazaki, Shinji; Sakakibara, Tsutomu

    Advantageous aspects of sandwich-type reinforced earth structures combined with geosynthetics and sand mat are highlighted in this paper. Those aspects were elucidated by two kinds of laboratory tests : (1) large consolidation tests for improvement of hydraulic conductivity and (2) model footing tests on improvement of bearing capacity and deformation characteristics for reinforced earth structures, including both vertical permeability and horizontal transmissibility characteristics of geosynthetics results from both laboratory tests indicated the following: i) Hydraulic conductivity of geosynthetics used for this type of earth reinforcement can be maintained for a long period. Such conductivity sometimes disappears, particularly because of clogging when geosynthetics are adopted in embankment construction using fine-grained soils. This fact indicates that the sand mats which are laid above and beneath geosynthetics play a salient role in preventing clogging of geosynthetics that occurs by intrusion of fines from cohesive soils. ii) Sandwich-type reinforcement combined with geosynthetics and sand mats increases stability and decreases deformation of earth structures. In particular, the sandwich structure is effective for providing toughness, which has remained an important issue for reducing infrastructural maintenance and costs. In the later part of the paper, conventionally available stability analysis was carried out to propose the design procedure for reinforced earth structures and at the same time numerical analysis was also conducted to ensure the applicability of the hybrid-sandwiched earth reinforcement newly proposed in the current paper. Finally, based on the horizontal placement by means of HBS described in the current paper, the vertical drain procedure using the sandwich structures for accelerating consolidation and increasing stability of soft soils is also suggested for the future research and investigation.

    What are the experiences of students and clinical educators in a paired student placement model incorporating facilitated peer-assisted learning (PAL) activities, compared to a traditional paired teaching approach? Qualitative study utilising focus groups. Twenty-four physiotherapy students and 12 clinical educators. Participants in this study had experienced two models of physiotherapy clinical undergraduate education: a traditional paired model (usual clinical supervision and learning activities led by clinical educators supervising pairs of students) and a PAL model (a standardised series of learning activities undertaken by student pairs and clinical educators to facilitate peer interaction using guided strategies). Peer-assisted learning appears to reduce the students' anxiety, enhance their sense of safety in the learning environment, reduce educator burden, maximise the use of downtime, and build professional skills including collaboration and feedback. While PAL adds to the clinical learning experience, it is not considered to be a substitute for observation of the clinical educator, expert feedback and guidance, or hands-on immersive learning activities. Cohesion of the student-student relationship was seen as an enabler of successful PAL. Students and educators perceive that PAL can help to position students as active learners through reduced dependence on the clinical educator, heightened roles in observing practice, and making and communicating evaluative judgments about quality of practice. The role of the clinical educator is not diminished with PAL, but rather is central in designing flexible and meaningful peer-based experiences and in balancing PAL with independent learning opportunities.

    Background. Gli ambienti di apprendimento clinico sono definiti come una rete di fattori interagenti nel contesto, in grado di influenzare gli esiti dell’apprendimento degli studenti. La soddisfazione degli studenti è considerata un indicatore del raggiungimento degli esiti dell’apprendimento ed è determinante a partire dalla prima esperienza di tirocinio. Scopo. Analizzare l’esperienza di apprendimento clinico degli studenti infermieri del primo anno di corso dopo il primo tirocinio clinico ed identificare i principali determinanti della soddisfazione degli studenti. Metodo. Lo studio osservazionale è stato realizzato in cinque sedi universitarie italiane del Corso di Laurea in Infermieristica. 420 studenti hanno compilato la versione italiana della “Clinical Learning Environment, Supervision and plus Nurse Teacher (CLES+T) scale” al termine del primo tirocinio clinico. Risultati. I punteggi medi assegnati alle dimensioni della scala variano da 4.02 (clima di apprendimento) a 3.30 (relazione di tutorato). La maggior parte degli studenti è soddisfatto della propria esperienza di tirocinio (75.6%), ma sono emerse differenze in relazione alle diverse sedi di tirocinio clinico. Discussione. I principali determinanti della soddisfazione sono lo stile di leadership del coordinatore infermieristico e l’integrazione teoria-pratica nella relazione fra tutor clinico, universitario e studente. Conclusioni. I risultati dello studio contribuiscono alla comprensione della prima esperienza di tirocinio degli studenti. Tuttavia, sono necessarie ulteriori ricerche per determinare le variabili organizzative specifiche e i modelli tutoriali in grado di aumentare la soddisfazione degli studenti, per sviluppare strategie formative basate sull’integrazione tra tutor universitari e guide di tirocinio.

  17. An investigation into trends in Advanced Placement test taking in science and mathematics among student sub-populations using a longitudinal growth model

    Science.gov (United States)

    Campbell, D. Michael

    The lack of preparation, participation, and equal access of students in mathematics and the science education continues to afflict America's high school system (Ratliff, 2001). Additionally, gender and ethnic status have become significant factors as females and minority subgroups such as African Americans and Hispanics continue to be underrepresented in these two subject fields. Recognizing and understanding these trends is extremely important for the future of this country. As fewer minorities and females become involved in advanced mathematics and science curriculum there will be a continued lack of minorities and females in mathematics and science careers. Additionally, this insufficient representation leads to fewer numbers of females and minorities in industry and educational leadership positions in mathematics and science to promote participation and equality in these fields. According to Brainard and Carlin (2003) as trends currently stand, these two groups will be under-represented in the fields of math and science and will continue to be denied economic and social power. Thus, a better understanding of these trends in participation in mathematics and science among these groups of students is warranted. This study is intended to accomplish four objectives. The first objective is to identify the extent to which opportunities are increasing or decreasing for students in high schools taking mathematics and science Advanced Placement exams by examining six years of student testing data from the College Board. A second objective is to identify features of high schools that relate to greater expansion in Advanced Placement test taking for females and minority groups in the areas of both math and science. A third objective is to explore whether, and to what extent, any social or educational features such as economic status, regional school and living locations, and ethnic backgrounds have enhanced or reduced Advanced Placement testing in these schools.

De esta forma, la universidad reconoce que estas prácticas tienen un valor pedagógico y asume cierta responsabilidad en que así sea. Para llevar a cabo la difícil tarea aparejada a esa responsabilidad es necesario conocer cómo los estudiantes realizan prácticas profesionales en la actualidad, y reflexionar acerca de los aspectos que deben ser mejorados. Este trabajo trata de contribuir a este proceso de reflexión, cuya finalidad última es que las primeras experiencias laborales de los estudiantes de Periodismo sean formativas en un sentido integro: ayuden a asimilar habilidades, conocimientos y compromiso social. More and more media students complete their studies with professional placements every year. At the same time, each year more universities include such experience as an integral part of their curricula. This is in recognition of the fact that a learning process takes place during placements. Therefore, universities offering such training placements have to accept some responsibility for their success. Universities need to be aware of what students do during these periods of training in order to face the challenge posed by this responsibility. By doing this, universities will know which things need to be improved. This paper aims to generate debate on the following topic: the first work experience of media students should be fully educational and should transfer knowledge, skills and social engagement.

    International PhD internship, named "Sandwich PhD" in Brazil is an opportunity to improve research abilities, to become known in academic area and to establish and/or increase work opportunities in an international context. In this article, we describe key factors regarding the planning and development of the "Sandwich PhD" as experienced by professors and students involved in the collaboration between the School of Nursing, University of São Paulo and Lawrence S. Bloomberg Faculty of Nursing, University of Toronto, Canada. We also present the participation of PhD students' network as an alternative to the "Sandwich PhD". An international experience, when well-planned and developed correctly, promotes students' personal and professional development and favors the internationalization of Brazilian graduate programs and research groups.

  3. The asymmetric sandwich theorem

    Simons, Stephen

    2011-01-01

    We discuss the asymmetric sandwich theorem, a generalization of the Hahn-Banach theorem. As applications, we derive various results on the existence of linear functionals that include bivariate, trivariate and quadrivariate generalizations of the Fenchel duality theorem. Most of the results are about affine functions defined on convex subsets of vector spaces, rather than linear functions defined on vector spaces. We consider both results that use a simple boundedness hypothesis (as in Rockafellar's version of the Fenchel duality theorem) and also results that use Baire's theorem (as in the Robinson-Attouch-Brezis version of the Fenchel duality theorem). This paper also contains some new results about metrizable topological vector spaces that are not necessarily locally convex.

  4. Fracture of sandwiched composites

    1989-01-01

    Fracture of a pair of collinear cracks in various materials, such as an isotropic strip, an orthotropic strip, a bonded isotropic adhesive layer, and sandwiched orthotropic layers, is investigated. The crack surfaces are subjected to an arbitrary opening pressure p(x). The problems are formulated in terms of Fredholm integral equation of the second kind by making use the techniques of Fourier transform and finite Hilbert transform. In case of uniform opening pressure p(x)={sigma}, exact expressions for the stress intensity factors and the shape of deformed crack are obtained. Numerical calculations are carried out to study the effects of various boundary geometries and material properties on the fracture of the chosen materials.

    Ruston, Annmarie; Tavabie, Abdol

    2011-01-01

    To report the extent to which the placement of paramedic practitioner students (PPSs) in accredited general practice (GP) training practices supported their development as autonomous, patient-centred practitioners and fostered interprofessional learning. A case study method was used. Sources of data included semi-structured telephone interviews (eight PPSs, eight GP trainers), an online end of placement survey and placement and assessment documentation. Interview data were transcribed and analysed using the constant comparative method. Accredited training practices in South East England. All respondents were positive that the placement provided a high-quality interprofessional learning environment which provided PPSs with learning opportunities based on assessed need, the support of experienced trainers and access to a wide range of patients and learning situations. The placement enabled PPSs to acquire the appropriate skills, knowledge and understanding to act as autonomous, patient-centred practitioners. The placement provides a sound model for expanding the skills of paramedic practitioners in order to meet the increasing demands for patient-centred, community based health care. It provided them with the skills to treat patients closer to home rather than automatically transporting them to hospital.

  9. Supporting student mental health nurses in clinical placement through virtual in-practice support (VIPS): Innovation uptake and the 'VIPS' project.

    Hardy, Sally; Mushore, Manyara; Goddard, Linda

    2016-11-01

    The integration of technology in nurse education has become an essential element of academic practice. Yet innovation uptake between academic institutions across the four countries of the UK and their clinical practice partners has proved problematic, leading to a slow introduction of digitally enhanced teaching and learning innovations, particularly in the area of clinical decision making and leadership. The Virtual in Practice Support (VIPS) project involved two academic institutions working with the same mental health care service partner aiming to maximise student clinical placement learning. Student nurses in their final year of training were invited to take part in testing the viability of distance e-tutoring (via computer access to academic nurse lecturers) for facilitated critical reflection. An evaluation of the use of video linked conference sessions, set up for students to undertake a group based online (i.e. virtual) group tutorial is presented. All participants completed an evaluation data sheet using a five point Likert scale and free text evaluation feedback form completed at the end of each online tutorial session. Students were also invited to a focus group and all tutors were interviewed at the completion of the project. The VIPS project findings highlight; i) the importance of a clear project vision for innovation uptake ii) consequences of working with innovation champions and iii) how technology can be used to maximise student learning across geographical distance through online facilitated group critical discussion. VIPS' participants were able to articulate positive outcomes as a result of engaging in a multi-institutional project that capitalised on the richness of nursing clinical practice learning experience for both the students and the academics involved as innovation champions.

  13. Tools to reduce first year nursing students' anxiety levels prior to undergoing objective structured clinical assessment (OSCA) and how this impacts on the student's experience of their first clinical placement.

    Science.gov (United States)

    Stunden, Annette; Halcomb, Elizabeth; Jefferies, Diana

    2015-09-01

    One form of assessment that tests students' theoretical skills and confidence in their clinical practice is known as the Objective Structured Clinical Assessment (OSCA). Traditionally it was first launched from medical education, and is now being incorporated by other disciplines, such as nursing. This review seeks to present the best available evidence into strategies that help reduce first year nursing students' anxiety levels prior to undergoing OSCA and clinical placement. A systematic literature search was performed using Medline and CINAHL. This review considered any English language original research published between 2005 and 2013. A literature search located 117 articles. Eight articles were identified as meeting the inclusion in criteria. Majority of studies reported simulation session prior to the OSCA increased students confidence and reduced their anxiety levels. This resulted in students' reporting that they valued the OSCA as a worthwhile assessment. However there were four major themes: that students were anxious about attending the OSCA; that adequate preparation was seen as a coping strategy; that simulation was a further cause for anxiety; and that the simulation experience could also be used as an OSCA tool. Students who have been exposed to simulation scenarios before the OSCA are able to cope much better during the OSCA. Therefore, it is highly recommended to incorporate simulation scenarios into the nursing curricula for first year nursing students' clinical units to help reduce their anxiety levels prior to OCSA.

  18. A new surgical management for oro-antral communication: the resorbable guided tissue regeneration membrane--bone substitute sandwich technique.

    Science.gov (United States)

    Ogunsalu, C

    2005-09-01

    This paper describes a new technique for the closure of oro-antral fistula/communication, in which both hard tissue (bone) and soft tissue closure is achieved. The sandwich technique utilizes a suitable bone grafting material sandwiched between two sheaths of Biogide (a resorbable membrane) for the hard tissue closure of oro-antral communication post traumatic exodontia. The bone grafting material utilized for this case was Bio-oss. The result obtained was excellent with regeneration of sufficient bony tissue to allow placement of an endosseous implant. This sandwich technique is a simple and excellent technique for the closure of oro-antral communication, especially when subsequent placement of endosseous implant is considered without the need of donor site surgery for bone grafting. The otorhinolaryngologists and oral and maxillofacial surgeons should find this technique very useful in the closure of oro-antral fistulae.

  2. High temperature structural sandwich panels

    Science.gov (United States)

    Papakonstantinou, Christos G.

    High strength composites are being used for making lightweight structural panels that are being employed in aerospace, naval and automotive structures. Recently, there is renewed interest in use of these panels. The major problem of most commercial available sandwich panels is the fire resistance. A recently developed inorganic matrix is investigated for use in cases where fire and high temperature resistance are necessary. The focus of this dissertation is the development of a fireproof composite structural system. Sandwich panels made with polysialate matrices have an excellent potential for use in applications where exposure to high temperatures or fire is a concern. Commercial available sandwich panels will soften and lose nearly all of their compressive strength temperatures lower than 400°C. This dissertation consists of the state of the art, the experimental investigation and the analytical modeling. The state of the art covers the performance of existing high temperature composites, sandwich panels and reinforced concrete beams strengthened with Fiber Reinforced Polymers (FRP). The experimental part consists of four major components: (i) Development of a fireproof syntactic foam with maximum specific strength, (ii) Development of a lightweight syntactic foam based on polystyrene spheres, (iii) Development of the composite system for the skins. The variables are the skin thickness, modulus of elasticity of skin and high temperature resistance, and (iv) Experimental evaluation of the flexural behavior of sandwich panels. Analytical modeling consists of a model for the flexural behavior of lightweight sandwich panels, and a model for deflection calculations of reinforced concrete beams strengthened with FRP subjected to fatigue loading. The experimental and analytical results show that sandwich panels made with polysialate matrices and ceramic spheres do not lose their load bearing capability during severe fire exposure, where temperatures reach several

  10. Where Should We Go With Advanced Placement?

    Science.gov (United States)

    Lichten, William

    2001-04-01

    This is a review of the Advanced Placement (AP)Program. In disagreement with claims of the College Board, there is firm evidence that the average test performance level has dropped. The College Board's scale and claims for AP qualification disagree seriously with college standards. A majority of tests taken do not qualify. It appears that "advanced placement" is coming closer to "placement." This paper recommends that the College Board's policy, which previously has concentrated on the numbers of participants, should include an emphasis on student performance and program quality. AP could accomplish its goal of reaching a wider range of students by changing along the lines followed in college introductory physics courses: multiple tracks.

    Full Text Available Background. Whilst placement supervision and clinical education programmes are of significant value in shaping the behaviours of undergraduate healthcare students, appropriate provisions which are efficacious to the learner are somewhat lacking, particularly for students studying on UK MPharm programmes. Objectives. To explore and explain the value of placement supervision to the personal development and employability of undergraduate pharmacy students. Methods. Students participated in a week long community pharmacy pilot programme, a result of a collaborative effort between the School of Pharmacy and Life Sciences and a small consortium of community pharmacies. Students and stakeholders were asked to evaluate their experiences via separate questionnaires which had been developed to elicit views and attitudes. Key Findings. Feedback from students and stakeholders towards the experience was overwhelmingly positive with multiple benefits being reported. Of particular prominence was the emphasis in student feedback on the value of placement supervision to their professional and personal development. Findings were indicative of a development in clinical practice proficiencies, core skills, and improvement in decision-making practice. Conclusions. The benefits of clinical supervision to the professional and personal development of MPharm students are well documented, although attracting professional pharmacy supervisors is proving a problematic task for educational providers in the UK.

    2001-01-01

    This study explored the feasibility and potential benefits provided by the addition of through-the-thickness reinforcement to sandwich structures. Through-the-thickness stitching is proposed to increase the interlaminar strength and damage tolerance of composite sandwich structures. A low-cost, out-of-autoclave processing method was developed to produce composite sandwich panels with carbon fiber face sheets, a closed-cell foam core, and through-the-thickness Kevlar stitching. The sandwich panels were stitched in a dry preform state, vacuum bagged, and infiltrated using Vacuum Assisted Resin Transfer Molding (VARTM) processing. For comparison purposes, unstitched sandwich panels were produced using the same materials and manufacturing methodology. Test panels were produced initially at the University of Utah and later at NASA Langley Research Center. Four types of mechanical tests were performed: flexural testing, flatwise tensile testing, core shear testing, and edgewise compression testing. Drop-weight impact testing followed by specimen sectioning was performed to characterize the damage resistance of stitched sandwich panels. Compression after impact (CAI) testing was performed to evaluate the damage tolerance of the sandwich panels. Results show significant increases in the flexural stiffness and strength, out-of-plane tensile strength, core shear strength, edgewise compression strength, and compression-after-impact strength of stitched sandwich structures.

    Full Text Available Product placement is a marketing approach for integrating products or services into selected media content. Studies have shown that the impact of advertising on children and youth are large, and that it can affect their preferences and attitudes. The aim of this article is to determine the existing level of product placement in cartoons that are broadcast on Croatian television stations. Content analysis of cartoons in a period of one month gave the following results: in 30% of cartoons product placement was found; most product placement were visual ads, in 89%, however, auditory product placement and plot connection was also found. Most ads were related to toys and it is significant that even 65% of cartoons are accompanied by a large amount of products available on the Croatian market. This is the result of two sales strategies: brand licensing (selling popular cartoon characters to toys, food or clothing companies and cartoon production based on existing line of toys with the sole aim of making their sales more effective.

  3. New "sandwich" structures conformed from three dimensional

    Alba, Juan J.

    1996-03-01

    Full Text Available Poor interlaminar properties as well as poor-skin-to-core adhesion properties are very often the common existing problems we find when designing with "sandwich" structures. A new type of 3D-fabric "sandwich" structure is being developed in order to avoid these problems. Although the manufacturing process is very simple, a very complex "sandwich" structure is obtained as a result of the complexity of the 3D-fabric used. This 3D-fabric is a 3D woven glass fabric produced on velvet weaving machines with glass yarns. It is an integrally woven "sandwich" laminate for all kinds of composite products. The strength of the vertical fibers makes, that also after impregnation with a resin matrix, the "sandwich" structure is maintained. The result is a laminate with high strength and stiffness and low weight. On each side of this "sandwich" laminate additional reinforcement materials can be laminated and a synthetic foam can be injected in the hollow structure. This will allow to establish the mechanical properties of a finished product.

    Las pobres propiedades, tanto interlaminares como de adhesión entre piel y núcleo, constituyen uno de los grandes problemas cuando se diseñan estructuras utilizando paneles tipo "sandwich". Un nuevo tipo de panel "sandwich", configurado a partir de tejidos tridimensionales, está siendo desarrollado en la actualidad con el objetivo de eliminar esos problemas. Aunque el proceso de fabricación es muy simple, el panel "sandwich" obtenido es de estructura compleja, como resultado de la complejidad del tejido tridimensional utilizado. Este tejido tridimensional (3D es un tejido de fibra de vidrio producido en máquinas de tejer especializadas.

    Poor interlaminar properties as well as poor-skin-to-core adhesion properties are very often the common existing problems we find when designing with "sandwich" structures. A new type of 3D-fabric "sandwich" structure is being developed in order to avoid these problems. Although the manufacturing process is very simple, a very complex "sandwich" structure is obtained as a result of the complexity of the 3D-fabric used. This 3D-fabric is a 3D woven glass fabric produced on velvet weaving machi...

  5. First impressions count: does FAIRness affect adaptation of clinical clerks in their first clinical placement?

    2013-09-01

    FAIRness (Feedback, Activity, Individualisation, Relevance) teaching is a structured program, comprising series of classes in which student work is anonymised and reviewed by the whole class, as well as students receiving private feedback on their written work. The class work emphasises logic, structure and order in history and examination, with a diagnostic and management focus. The effect of FAIRness teaching methods on the adaptation of medical students entering their first clinical rotations was studied. 18 students in FAIRness placements and 72 students in conventional placements, all in medical/surgical units in the same University teaching hospital were studied. They completed questionnaires relating to effectiveness and quality of clinical teaching. Some students additionally attended focus groups, at the start of placement to discuss their expectations, and after 3 weeks, to discuss their adaptation to the clinical learning environment. All students entering clinical placements had low expectations of their future teaching. Students in standard placements still expressed negative attitudes after 3 weeks, while students on FAIRness placements felt positive. Students in FAIRness placements scored significantly higher on questions related to feedback and review of student work. FAIRness teaching practices help students to adapt to their first clinical placements.

    Østergaard, Rasmus Christian

    2008-01-01

    A compression loaded sandwich column that contains a debond is analyzed using a geometrically non-linear finite element model. The model includes a cohesive zone along one face sheet/core interface whereby the debond can extend by interface crack growth. Two geometrical imperfections are introduced......; a global imperfection of the sandwich column axis and a local imperfection of the debonded face sheet axis. The model predicts the sandwich column to be very sensitive to the initial debond length and the local face sheet imperfection. The study shows that the sensitivity to the face sheet imperfection...... results from two mechanisms: (a) interaction of local debond buckling and global buckling and (b) the development of a damaged zone at the debond crack tip. Based on the pronounced imperfection sensitivity, the author predicts that an experimental measurement of the strength of sandwich structures may...

    The sandwiched surface singularities are those rational surface singularities which dominate birationally smooth surface singularities. de Jong and van Straten showed that one can reduce the study of the deformations of a sandwiched surface singularity to the study of deformations of a 1-dimensional object, a so-called decorated plane curve singularity. In particular, the Milnor fibers corresponding to their various smoothing components may be reconstructed up to diffeomorphisms from those de...

  10. Stochastic micro-vibration suppression of a sandwich plate using a magneto-rheological visco-elastomer core

    2014-02-01

    Magneto-rheological visco-elastomer (MRVE) is used to construct sandwich plates for micro-vibration control. The micro-vibration response of a sandwich plate with an MRVE core under stochastic support motion excitation is studied to evaluate the vibration suppression capability. The dynamic behavior of MRVE in micro-vibration is characterized by a non-homogeneous complex modulus dependent on the vibration frequency and controllable by an applied magnetic field, in which the effect of the localized magnetic field distribution is considered. The partial differential equations for the coupled transverse and longitudinal motions of the sandwich plate are derived from the dynamic equilibrium, constitutive and geometric relations. A frequency-domain solution method for the stochastic micro-vibration response of sandwich plates is developed based on the Galerkin method and random vibration theory. The partial differential equations are first converted into ordinary differential equations according to the Galerkin method. Then the expressions for the frequency-response function, response power spectral density and root-mean-square velocity spectrum in terms of the one-third octave frequency band for micro-vibration are obtained. Finally, numerical results are given to illustrate the high response reduction capacity of the MRVE sandwich plate under stochastic support motion excitation, and the influence of the MRVE parameters and localized magnetic field placement on the micro-vibration response.

    2000-04-01

    Nurses who had just completed their training in Scotland were interviewed with regard to their experiences on placements. The nurses had either completed a traditional training course or came from the first cohort of the Project 2000 diploma level course. The interviews focused on the way in which the student nurses had learned in their practice placements. The results suggest that the placement is a complex social and cognitive experience in which there are elements of situated learning. Acceptance into the community of practice is important but this can be separated, conceptually at least, into a social acceptance which might be extended to any student and a professional acceptance which relies on the display of appropriate competence. The nurses described the way in which their mentors had interacted with them in terms which suggested that cognitive apprenticeship strategies had been used to further their learning in practice. It is concluded that, in view of the central importance of the placement for training nurses, explicit use of mentoring techniques derived from situated learning and cognitive apprenticeship might be beneficial.

    2008-01-15

    A multifunctional sandwich panel combining efficient structural load support and thermal management characteristics has been designed and experimentally assessed. The concept is based upon a truncated, square honeycomb sandwich structure. In closed cell honeycomb structures, the transport of heat from one face to the other occurs by a combination of conduction through the webs and convection/radiation within the cells. Here, much more effective heat transport is achieved by multifunctionally utilizing the core as a heat pipe sandwich panel. Its interior consists of a 6061 aluminum truncated-square honeycomb core covered with a stochastic open-cell nickel foam wick. An electroless nickel plating barrier layer inhibited the chemical reaction between the deionized water working fluid and the aluminum structure, retarding the generation of non-condensable hydrogen gas. A thermodynamic model was used to guide the design of the heat pipe sandwich panel. We describe the results of a series of experiments that validate the operational principle of the multifunctional heat pipe sandwich panel and characterize its transient response to an intense localized heat source. The systems measured thermal response to a localized heat source agrees well with that predicted by a finite difference method model used to predict the thermal response. (author)

  17. Sandwich Panels Evaluated With Ultrasonic Spectroscopy

    2004-01-01

    Enhanced, lightweight material systems, such as 17-4PH stainless steel sandwich panels are being developed for use as fan blades and fan containment systems for next-generation engines. The bond strength between the core and face sheets is critical in maintaining the structural integrity of the sandwich structure. To improve the inspection and production of these systems, researchers at the NASA Glenn Research Center are using nondestructive evaluation (NDE) techniques, such as ultrasonic spectroscopy, to evaluate the brazing quality between the face plates and the metallic foam core. The capabilities and limitations of a swept-frequency approach to ultrasonic spectroscopy were evaluated with respect to these sandwich structures. This report discusses results from three regions of a sandwich panel representing different levels of brazing quality between the outer face plates and a metallic foam core. Each region was investigated with ultrasonic spectroscopy. Then, on the basis of the NDE results, three shear specimens sectioned from the sandwich panel to contain each of these regions were mechanically tested.

    2014-03-01

    Full Text Available Background: Thoracoscopy reduces the morbidity of open thoracotomy. The placement of camera and working ports is crucial for successful completion of the procedure. Methods: A retrospective review of video assisted thoracoscopic surgeries performed during January 2011 to June 2013 at the university surgical unit, Peradeniya, Sri Lanka was done. Port placement of each surgery was identified and the adequacy of space for dissection, use of additional ports for retractors, successful, comfortable and safe completion of the surgery with regard to average operative time, mean blood loss and conversions to open surgery were noted. Results: 9 different thoracoscopic procedures were performed on 67 patients. All procedures allowed comfortable dissection, adequate space for dissection and required no additional ports for retractors except for thymectomy and excision of retrosternal goiter. Time taken was acceptable with minimum blood loss and no conversions. Conclusion: For anterior and posterior mediastinal procedures the camera port was placed in the mid and the posterior axillary lines respectively and provided a clear display of the anatomy. The thirty degree camera was preferred as it provided a wider visual field. Working ports for anterior and posterior mediastinal procedures were placed in the anterior and mid axillary line respectively. Most effective placement for working ports were found to be two intercostal spaces above and below the camera port.

  19. Novel 1-D Sandwich Photonic Bandgap Structure

    Institute of Scientific and Technical Information of China (English)

    庞云波; 高葆新

    2004-01-01

    A sandwich photonic bandgap (PBG) structure is a novel PBG structure whose periodic lattice is buried in the middle of a substrate. Neither drilling nor suspending the substrate is required, and the integrity of the ground plane is maintained. This paper presents several modification techniques for sandwich PBG structure fabrication. The forbidden gap can be improved by adopting the chirping technique, applying the tapering technique, enlarging the periodic elements, adjusting the location of the periodic lattice in the substrate, and using different dielectric media H-shape elements. A finite difference time domain method is applied to analyze the structures. Deep and wide stopbands can be obtained using the modified sandwich structures. Experimental measurement results agree well with the theoretical analysis.

    Two analytical techniques applicable to large deflection dynamic response calculations for pressure loaded composite sandwich panels are demonstrated. One technique utilizes finite element modeling with a single equivalent layer representing the face sheets and core. The other technique utilizes the modal analysis computer code DEPROP which was recently modified to include transverse shear deformation in a core layer. The example problem consists of a simply supported rectangular sandwich panel. Included are comparisons of linear and nonlinear static response calculations, in addition to dynamic response calculations.

    Full Text Available In this paper, we show the optimal design of the three-layered sandwich plates. The objective function contains the material and fabrication costs. The design constraints are the maximal stresses, the deflection of plates and damping of vibrations. The unknown is the thickness of the filling foam. By the mathematical method, we define the minima of the cost function and the optimal thickness of the filling layer of foam. The active constraint is the deflection, so we calculate of the costs of the sandwich plate with the homogeneous plate.

    Placement of gastrostomy tubes in infants and children has become increasingly commonplace. A historical emphasis on use of open gastrostomy has been replaced by less invasive methods of placement, including percutaneous endoscopic gastrostomy and laparoscopically assisted gastrostomy procedures. Various complications, ranging from minor to the more severe, have been reported with all methods of placement. Many pediatric patients who undergo gastrostomy tube placement will require long-term enteral therapy. Given the prolonged time pediatric patients may remain enterally dependent, further quality improvement and education initiatives are needed to improve long-term care and outcomes of these patients.

    The Sandwich Panel Technologies including Structural Insulated Panels (SIPs) can be used to replace the conventional wooden-frame construction method. The main purpose of this Cooperative Research and Development Agreement (CRADA) between UT-Battelle, LLC and SGI Venture, Inc. was to design a novel high R-value type of metal sandwich panelized technology. This CRADA project report presents design concept discussion and numerical analysis results from thermal performance study of this new building envelope system. The main objective of this work was to develop a basic concept of a new generation of wall panel technologies which will have R-value over R-20 will use thermal mass to improve energy performance in cooling dominated climates and will be 100% termite resistant. The main advantages of using sandwich panels are as follows: (1) better energy saving structural panels with high and uniform overall wall R-value across the elevation that could not be achieved in traditional walls; and (2) reducing the use of raw materials or need for virgin lumber. For better utilization of these Sandwich panels, engineers need to have a thorough understanding of the actual performance of the panels and system. Detailed analysis and study on the capacities and deformation of individual panels and its assembly have to be performed to achieve that goal. The major project activity was to conduct structural analysis of the stresses, strains, load capacities, and deformations of individual sandwich components under various load cases. The analysis simulated the actual loading conditions of the regular residential building and used actual material properties of the steel facings and foam.

    Recent research has demonstrated that longitudinal integrated placements (LICs) are an alternative mode of clinical education to traditional placements. Extended student engagement in community settings provide the advantages of educational continuity as well as increased service provision in underserved areas. Developing and maintaining LICs require a differing approach to student learning than that for traditional placements. There has been little theoretically informed empirical research that has offered explanations of which are the important factors that promote student learning in LICs and the relationships between those factors. We explored the relationship between student learning, student perceptions of preparedness for practice and student engagement, in the context of a rural LIC. We used a sequential qualitative design employing thematic, comparative and relational analysis of data from student interviews (n = 18) to understand possible processes and mechanisms of student learning in the LIC. Through the theoretical lens of social learning systems, we identified two major themes; connectivity and preparedness for practice. Connectivity described engagement and relationship building by students, across formal and informal learning experiences, interprofessional interactions, social interactions with colleagues, interaction with patients outside of the clinical setting, and the extent of integration in the wider community. Preparedness for practice, reflected students' perceptions of having sufficient depth in clinical skills, personal and professional development, cultural awareness and understanding of the health system, to work in that system. A comparative analysis compared the nature and variation of learning across students. In a relational analysis, there was a positive association between connectivity and preparedness for practice. Connectivity is a powerful enabler of students' agentic engagement, collaboration, and learning within an LIC. It

  12. On the Milnor fibers of sandwiched singularities

    CERN Document Server

    Nemethi, Andras

    2009-01-01

    The sandwiched surface singularities are those rational surface singularities which dominate birationally smooth surface singularities. de Jong and van Straten showed that one can reduce the study of the deformations of a sandwiched surface singularity to the study of deformations of a 1-dimensional object, a so-called decorated plane curve singularity. In particular, the Milnor fibers corresponding to their various smoothing components may be reconstructed up to diffeomorphisms from those deformations of associated decorated curves which have only ordinary singularities. Part of the topology of such a deformation is encoded in the incidence matrix between the irreducible components of the deformed curve and the points which decorate it, well-defined up to permutations of columns. Extending a previous theorem ofours, which treated the case of cyclic quotient singularities, we show that the Milnor fibers which correspond to deformations whose incidence matrices are different up to permutations of columns are n...

    Full Text Available Lightweight sandwich panels consisting of bamboo faces and oil palm trunk core were manufactured using melamine urea formaldehyde with the resin content of 250 g/m2 (solid basis. The parameters examined were node and density of bamboo faces. Physical (board density, thickness swelling and water absorption and mechanical (modulus of elasticity and modulus of rupture properties of the sandwich board obtained were investigated and compared with other bamboo products and commercial wood based products. Result showed that this panel had better dimensional stability than those of other bamboo products but lower bending strength. Node of bamboo had no significant effect on any board properties examined. Most of board properties were influenced by bamboo face density. Comparing the properties to commercial wood based products, this panel could be used as wall/floor applications.

    Enhanced, lightweight material systems, such as 17-4PH stainless steel sandwich panels are being developed for use as fan blades and fan containment material systems for next generation engines. In order to improve the production for these systems, nondestructive evaluation (NDE) techniques, such as ultrasonic spectroscopy, are being utilized to evaluate the brazing quality between the 17-4PH stainless steel face plates and the 17-4PH stainless steel foam core. Based on NDE data, shear tests are performed on sections representing various levels of brazing quality from an initial batch of these sandwich structures. Metallographic characterization of brazing is done to corroborate NDE findings and the observed shear failure mechanisms.

    Abouhamzeh, M.; Sadighi, M.

    2016-06-01

    In this paper, the buckling load optimisation is performed on sandwich cylindrical panels. A finite element program is developed in MATLAB to solve the governing differential equations of the global buckling of the structure. In order to find the optimal solution, the genetic algorithm Toolbox in MATLAB is implemented. Verifications are made for both the buckling finite element code and also the results from the genetic algorithm by comparisons to the results available in literature. Sandwich cylindrical panels are optimised for the buckling strength with isotropic or orthotropic cores with different boundary conditions. Results are presented in terms of stacking sequence of fibers in the face sheets and core to face sheet thickness ratio.

    Fugon, D.; Chen, C.; Peters, K.

    2012-04-01

    Previous research demonstrated that a thin self-healing layer is effective in recovering partial sandwich composite performance after an impact event. Many studies have been conducted that show the possibility of using Fiber Bragg Grating (FBG) sensors to monitor the cure of a resin through strain and temperature monitoring. For this experiment, FBG sensors were used to monitor the curing process of a self-healing layer within a twelve-layer fiberglass laminate after impact. First, five self-healing sandwich composite specimens were manufactured. FBG sensors were embedded between the fiberglass and foam core. Then the fiberglass laminate was impacted with the use of a drop tower and the curing process was monitored. The collected data was used to compare the cure of the resin and fiberglass alone to the cure of the resin from a self-healing specimen. For the low viscosity resin system tested, these changes were not sufficiently large to identify different polymerization states in the resin as it cured. These results indicate that applying different resin systems might increase the efficiency of the self-healing in the sandwich composites.

  19. Mixed auxeticity of auxetic sandwich structures

    Energy Technology Data Exchange (ETDEWEB)

    Lim, Teik-Cheng [SIM University, Singapore (Singapore)

    2012-07-15

    Previously, a sandwich structure in which the Poisson ratios of the core and facesheets possess opposite signs has been shown to exhibit overall conventional and auxetic behavior depending on the loading mode - axial loading or bending - for an intermediate range of relative core thickness. In addition to these two loading modes, sandwich structures in aerospace applications encounter torsional loads. In this paper, the effective Poisson's ratio for torsional loading is proposed. Results show that, depending on the loading mode and the relative core thickness, there can be up to four levels of overall auxeticity, namely (i) full auxeticity (FA) if the structure behaves as an auxetic structure under all three modes of loading, (ii) high auxeticity (HA) if the structure behaves as an auxetic structure in two of the loading modes, (iii) low auxeticity (LA) if the structure behaves as an auxetic structure in only one of the loading modes, and (iv) no auxeticity (NA) if the structure behaves as a conventional structure under all of the three loading modes. These results indicate that by selecting the Poisson's ratios and the thickness of the cores and facesheets, the sandwich structure can be made to respond differently under different external loading conditions.

    Beginning in 2010, the U.S. Department of Health and Human Services, Health Resources and Services Administration, made provisions in its Public Health Training Center cooperative agreements for field placements. This article describes best practices and lessons learned establishing and managing the South Central Public Health Partnership's Interns and Mentors Program for ACTion (IMPACT) Field Placement Program, which was initially funded through the Centers for Disease Control and Prevention's Centers for Public Health Preparedness Cooperative agreement in 2002. The IMPACT program is based on a six-step process that has been developed and refined over its 10-year history: (a) identifying field placement opportunities, (b) marketing field experience opportunities to students, (c) selecting students seeking field experience opportunities, (d) placing students with practice partners, students with practice partners, (e) evaluating student progress toward field experience objectives, and (f) evaluating the program. This article describes the program's structure and processes, delineates the roles of its academic and practice partners, discusses evidence of its effectiveness, and describes lessons learned from its decade-long history. Hopefully, this information will facilitate the establishment, management and evaluation of internship and field placement programs in other Public Health Training Centers and academic public health programs.

    2013-05-01

    Full Text Available The present study aims to analyze the effect of product placement on attitude change and takes into consideration psychological models of the mere exposure effect. A sample of high school students watched an excerpt from two widely-distributed movies in which several products were shown by using the technique known as product placement. The results indicate that students who saw the commercial brand liked the products more than those who didn’t see it. This effect, in line with the literature on the product placement effect, seems to be independent from the recognition of the brand in the movie excerpt. This study also shows that, in the high involvement condition, one exposure is enough to produce a positive attitude toward the brand.

    Investigation on the thermal conductivity of newspaper sandwiched aerated lightweight concrete (ALC) panels is the main purpose of this study. Various densities of ALC panels ranging from 1700, 1400 and 1100 kg/m{sup 3} with three different aerial intensities of newspaper sandwiched were produced. Investigation was limited to the effect of aerial intensity of newspaper sandwiched and the effect of density of ALC on thermal conductivity. It is found that the thermal conductivity of newspaper sandwiched ALC panels reduced remarkably compared to control ALC panels. The reduction was recorded at 18.0%, 21.8% and 20.7% correspond to densities of 1700, 1400 and 1100 kg/m{sup 3} with just a mere 0.05 g/cm{sup 2} aerial intensity of newspaper sandwiched. Newspaper sandwiched has a significant impact on the performance of thermal conductivity of ALC panels based on regression analysis. (author)

    2013-11-01

    Clinical nursing education in Germany has not received attention in nursing science and practice for a long time, as it often seems to be a more or less "formalized appendix" of nursing education. Several development projects of clinical education taking place are mainly focused on the qualification of clinical preceptors. However, the clinical context and its influence on learning processes have still not been sufficiently investigated. The aim of this study was the testing of a German version of the clinical learning environment and supervision and nurse teacher scale (CLES + T scale). The sample of the pilot study consists of first-, second- and third-year student nurses (n=240) of a university nursing school from January to March 2011. Psychometric testing of the instrument is carried out by selected methods of classical testing theories using SPPS 19. The results show transferability of all subcategories of the CLES + T scale in the non-academic nursing education system of a university hospital in Germany, without the teacher scale. The strongest factor is "supervisory relationship". The German version of the CLES + T scale may help to evaluate and compare traditional and new models in clinical nursing education.

    The loss of teeth followed by bone resorption often lead to defects in the alveolar ridge, making installation of dental implants difficult. Correction of such bone defects, especially lack of height of the ridge, is a difficult problem for all dental surgeons. This report describes the outcome of treatment after alveolar ridge augmentation in the atrophic posterior maxillary region via segmental sandwich osteotomy combined with placement of an interpositional autograft prior to placement of endosseous implants. The technique was successfully used to treat a deficiency in the vertical dimension of the posterior maxillary region. Six months after graft surgery, two implants were successfully placed in accordance with the original treatment protocol, and they survived for 9 years of follow-up.

    Sleight, David W.; Wang, John T.

    1995-01-01

    A sandwich panel with initial through-the-width debonds is analyzed to study the buckling of its faceskin when subject to an in-plane compressive load. The debonded faceskin is modeled as a beam on a Winkler elastic foundation in which the springs of the elastic foundation represent the sandwich foam. The Rayleigh-Ritz and finite-difference methods are used to predict the critical buckling load for various debond lengths and stiffnesses of the sandwich foam. The accuracy of the methods is assessed with a plane-strain finite-element analysis. Results indicate that the elastic foundation approach underpredicts buckling loads for sandwich panels with isotropic foam cores.

    Workplace learning (WPL) placements are a mandatory part of occupational therapy courses. There is some evidence that suggests WPL placements in international settings are beneficial for students' learning, and personal and professional development. The aim of this study was to explore the impact an international WPL placement in Vietnam had on the perceived personal and professional development of a group of Australian occupational therapy graduates. Interpretative phenomenological analysis was used to explore the perceptions of how participation in the Charles Sturt University School of Community Health's Vietnam placement influenced the personal and professional development of occupational therapy graduates. Individual semi-structured interviews were conducted with nine graduates who participated in the Vietnam placement when they were final year occupational therapy students. Interviews were audio-recorded, transcribed verbatim and individually analysed to identify key themes. Two major themes emerged from the analysis: becoming resourceful, resilient and confident, and becoming respectful of difference. The participants indicated that participation in the Vietnam placement had a positive impact on their personal and professional development. Participants indicated that the Vietnam placement enabled them to develop their resourcefulness, resilience, reasoning skills, cultural competence, confidence and independence, beyond what they felt would have achieved on a domestic placement. For these reason these participants found the placement a beneficial and worthwhile experience. © 2016 Occupational Therapy Australia.

    Full Text Available This paper has applied the constrained viscoelastic layer damping treatments to a cylindrical aluminum shell using layerwise displacement theory. The transverse shear, the normal strains, and the curved geometry are exactly taken into account in the present layerwise shell model, which can depict the zig-zag in-plane and out-of-plane displacements. The damped natural frequencies, modal loss factors, and frequency response functions of cylindrical viscoelastic aluminum shells are compared with those of the base thick aluminum panel without a viscoelastic layer. The thickness and damping ratio of the viscoelastic damping layer, the curvature of proposed cylindrical aluminum structure, and placement of damping layer of the aluminum panel were investigated using frequency response function. The presented results show that the sandwiched viscoelastic damping layer can effectively suppress vibration of cylindrical aluminum structure.

    Fixed a point O on a non-singular surface S and a complete mO-primary ideal I in its local ring, the curves on the surface X obtained by blowing-up I are studied in terms of the base points of I. Criteria for the principality of these curves are obtained. New formulas for their multiplicity, intersection numbers and order of singularity at the singularities of X are given. The semigroup of branches going through a sandwiched singularity is effectively determined, too.

  12. Failure modes of composite sandwich beams

    Directory of Open Access Journals (Sweden)

    Gdoutos E.

    2008-01-01

    Full Text Available A thorough investigation of failure behavior of composite sandwich beams under three-and four-point bending was undertaken. The beams were made of unidirectional carbon/epoxy facings and a PVC closed-cell foam core. The constituent materials were fully characterized and in the case of the foam core, failure envelopes were developed for general two-dimensional states of stress. Various failure modes including facing wrinkling, indentation failure and core failure were observed and compared with analytical predictions. The initiation, propagation and interaction of failure modes depend on the type of loading, constituent material properties and geometrical dimensions.

    We review the status of aluminum foam sandwich (AFS) technology and discuss both recent improvements of foaming technology and current application strategies. It is concluded that the quality of foams has improved in the past years but the costs are still very much the same. This is why applications in which metal foams have more than one function are more likely to be economically viable. The examples presented include electromagnetic shielding, carrier plates for mirrors, cooking equipment, architectural panels, and blast protection.

    Full Text Available This study presents a detailed characterization of the behavior of EPS sandwich panels subject to normal load taking into account several variables. For that, two experimental programs were performed, leading to the proposal of an analytical formulation to estimate the maximum load resisted. The results obtained show how the height of the panel, the material properties, the position and configuration of the reinforcement may affect the resistance of panels. Special attention should be given to the eccentric position of the reinforcement, which may reduce considerably the maximum load resisted. Some recommendations about the optimum placement of the reinforcement are proposed.El presente estudio se centra en la caracterización del comportamiento de paneles tipo Sandwich con hormigón y EPS sometidos a cargas normales de compresión y teniendo en cuenta diferentes variables. Para ello, se han realizado campañas experimentales, cuyos resultados muestran que los aspectos geométricos, las propiedades de los materiales, la posición y la configuración del refuerzo influyen de manera significativa en la resistencia de los paneles. Asimismo se propone una formulación analítica para estimar la máxima carga resistida por los mismos. El estudio muestra que es especialmente importante definir la posición de las armaduras en la sección transversal ya que la excentricidad de las mismas reduce la resistencia a compresión de los paneles.

    This book presents a broad view of the current state of the art regarding the dynamic response of composite and sandwich structures subjected to impacts and explosions. Each chapter combines a thorough assessment of the literature with original contributions made by the authors.  The first section deals with fluid-structure interactions in marine structures.  The first chapter focuses on hull slamming and particularly cases in which the deformation of the structure affects the motion of the fluid during the water entry of flexible hulls. Chapter 2 presents an extensive series of tests underwater and in the air to determine the effects of explosions on composite and sandwich structures.  Full-scale structures were subjected to significant explosive charges, and such results are extremely rare in the open literature.  Chapter 3 describes a simple geometrical theory of diffraction for describing the interaction of an underwater blast wave with submerged structures. The second section addresses the problem of...

  17. Sandwich materials for wind turbine blades

    Energy Technology Data Exchange (ETDEWEB)

    Thybo Thomsen, O. [Aalborg Univ., Dept. of Mechanical Engineering, Aalborg (Denmark)

    2006-07-01

    Wind turbine blades are being manufactured using polymer matrix composite materials (PMC), in a combination of monolithic (single skin) and sandwich composites. Present day designs are mainly based on glass fibre reinforced composites (GFRP), but for very large blades carbon fibre reinforced composites (CFRP) are being used increasingly, in addition to GFRP by several manufacturers to reduce the weight. The size of wind turbines have increased significantly over the last 25 years, and this trend is expected to continue in the future. Thus, it is anticipated that wind turbines with a rated power output in the range of 8-10 MW and a rotor diameter about 170-180 m will be developed and installed within the next 10-15 years. The paper presents an overview of current day design principles and materials technology applied for wind turbine blades, and it highlights the limitations and important design issues to be addressed for up-scaling of wind turbine blades from the current maximum length in excess of 61 m to blade lengths in the vicinity of 90 m as envisaged for future very large wind turbines. In particular, the paper discusses the potential advantages and challenges of applying sandwich type construction to a larger extent than is currently being practiced for the load carrying parts of wind turbine blades.

  18. Quantum radiation from a sandwich black hole

    Science.gov (United States)

    Frolov, Valeri P.; Zelnikov, Andrei

    2017-02-01

    We discuss quantum radiation of a massless scalar field from a spherically symmetric nonsingular black hole with a finite lifetime. Namely, we discuss a sandwich black-hole model, where a black hole is originally created by a collapse of a null shell of mass M , and later, after some time Δ V , it is disrupted by the collapse of the other shell with negative mass -M . We assume that between the shells the metric is static and either coincides with the Hayward metric or with a special generalization of it. We show that in both cases for a sufficiently large parameter Δ V the radiation after the formation of the black hole practically coincides with the Hawking result. We also calculate the radiation, emitted from the black hole interior. This radiation contains a peak at the moment when the second shell intersects the inner horizon. In the standard sandwich metric (with the Hayward interior) this outburst of energy is exponentially large. In the modified metric, which includes an additional nontrivial redshift parameter, this exponent is suppressed. This is a result of a significant decrease of the surface gravity of the inner horizon in the latter case. We discuss possible consequences of this result in the context of the self-consistency requirement for nonsingular models with quantum radiation.

    Rose, Cheryl A.; Moore, David F.; Knight, Norman F., Jr.; Rankin, Charles C.

    2002-01-01

    A comparative study of different modeling approaches for predicting sandwich panel buckling response is described. The study considers sandwich panels with anisotropic face sheets and a very thick core. Results from conventional analytical solutions for sandwich panel overall buckling and face-sheet-wrinkling type modes are compared with solutions obtained using different finite element modeling approaches. Finite element solutions are obtained using layered shell element models, with and without transverse shear flexibility, layered shell/solid element models, with shell elements for the face sheets and solid elements for the core, and sandwich models using a recently developed specialty sandwich element. Convergence characteristics of the shell/solid and sandwich element modeling approaches with respect to in-plane and through-the-thickness discretization, are demonstrated. Results of the study indicate that the specialty sandwich element provides an accurate and effective modeling approach for predicting both overall and localized sandwich panel buckling response. Furthermore, results indicate that anisotropy of the face sheets, along with the ratio of principle elastic moduli, affect the buckling response and these effects may not be represented accurately by analytical solutions. Modeling recommendations are also provided.

    In this work we address the problem of optimal sensor placement for a given region and task. An important issue in designing sensor arrays is the appropriate placement of the sensors such that they achieve a predefined goal. There are many problems that could be considered in the placement of multiple sensors. In this work we focus on the four problems identified by Hörster and Lienhart. To solve these problems, we propose an algorithm based on Direct Search, which is able to approach the global optimal solution within reasonable time and memory consumption. The algorithm is experimentally evaluated and the results are presented on two real floorplans. The experimental results show that our DS algorithm is able to improve the results given by the most performing heuristic introduced in. The algorithm is then extended to work also on continuous solution spaces, and 3D problems.

  9. Development, testing, and numerical modeling of a foam sandwich biocomposite

    Science.gov (United States)

    Chachra, Ricky

    This study develops a novel sandwich composite material using plant based materials for potential use in nonstructural building applications. The face sheets comprise woven hemp fabric and a sap based epoxy, while the core comprises castor oil based foam with waste rice hulls as reinforcement. Mechanical properties of the individual materials are tested in uniaxial compression and tension for the foam and hemp, respectively. The sandwich composite is tested in 3 point bending. Flexural results are compared to a finite element model developed in the commercial software Abaqus, and the validated model is then used to investigate alternate sandwich geometries. Sandwich model responses are compared to existing standards for nonstructural building panels, showing that the novel material is roughly half the strength of equally thick drywall. When space limitations are not an issue, a double thickness sandwich biocomposite is found to be a structurally acceptable replacement for standard gypsum drywall.

    A three-dimensionally favourable mandibular bone crest is desirable to be able to successfully implant placement to meet the aesthetic and functional criteria in the implant-prosthetic rehabilitation. Several surgical procedures have been advocated for bone augmentation of the atrophic mandible, and the sandwich osteotomy is one of these techniques. The aim of the present case report was to assess the suitability of segmental mandibular sandwich osteotomy combined with a tunnel technique of soft tissue. Based on our knowledge, nobody described before the sandwich osteotomy with tunnel technique to improve the healing of the wound and meet the dimensional requirements of preimplant bone augmentation in cases of a severely atrophic mandible. A 59-year-old woman with a severely atrophied right mandible was treated with the sandwich osteotomy technique filled with autologous bone graft harvested by a cortical bone collector from the ramus. Clinical examination revealed that the mandible was edentulous bilaterally from the first molar to the second molar region. Radiographically, atrophy of the mandibular alveolar ridge in the same teeth site was observed. We began to treat the right side. A horizontal osteotomy of the edentulous mandibular bone was then made with a piezoelectric device after tunnel technique of the soft tissue. The segmental mandibular sandwich osteotomy (SMSO) was finished by two (mesial and distal) slightly divergent vertical osteotomies. The entire bone fragment was displaced cranially, and the desirable position was obtained. The gap was filled completely with autologous bone chips harvested from the mandibular ramus through a cortical bone collector. No barrier membranes were used to protect the grafts. The vertical incisions were closing with interruptive suturing of the flaps with a resorbable material. In this way, the suture will not fall on the osteotomy line of the jaw; the result will be a better predictability of soft and hard tissue

    The organization of nanoparticles inside grafted polymer layers is governed by the interplay of polymer-induced entropic interactions and the action of externally applied fields. Earlier work had shown that strong external forces can drive the formation of colloidal structures in polymer brushes. Here we show that external fields are not essential to obtain such colloidal patterns: we report Monte Carlo and molecular dynamics simulations that demonstrate that ordered structures can be achieved by compressing a "sandwich" of two grafted polymer layers, or by squeezing a coated nanotube, with nanoparticles in between. We show that the pattern formation can be efficiently controlled by the applied pressure, while the characteristic length-scale, that is, the typical width of the patterns, is sensitive to the length of the polymers. Based on the results of the simulations, we derive an approximate equation of state for nanosandwiches.

    In this study, the Fiber-Metal Laminates (FMLs) containing glass fiber reinforced polypropylene (GFPP) and aluminum (Al) sheet were consolidated with Al foam cores for preparing the sandwich panels. The aim of this article is the comparison of the flexural properties of FML/Al foam sandwich panels bonded with various surface modification approaches (silane treatment and combination of silane treatment with polypropylene (PP) based film addition). The FML/foam sandwich systems were fabricated by laminating the components in a mould at 200 °C under 1.5 MPa pressure. The energy absorbtion capacities and flexural mechanical properties of the prepared sandwich systems were evaluated by mechanical tests. Experiments were performed on samples of varying foam thicknesses (8, 20 and 30 mm). The bonding among the sandwich components were achieved by various surface modification techniques. The Al sheet/Al foam sandwiches were also consolidated by bonding the components with an epoxy adhesive to reveal the effect of GFPP on the flexural performance of the sandwich structures.

    2014-05-01

    Wave propagation in sandwich panels with a poroelastic core, which is modeled by Biot's theory, is investigated using the waveguide finite element method. A waveguide poroelastic element is developed based on a displacement-pressure weak form. The dispersion curves of the sandwich panel are first identified as propagating or evanescent waves by varying the damping in the panel, and wave characteristics are analyzed by examining their motions. The energy distributions are calculated to identify the dominant motions. Simplified analytical models are also devised to show the main physics of the corresponding waves. This wave propagation analysis provides insight into the vibro-acoustic behavior of sandwich panels lined with elastic porous materials.

    Finite element thermal stress analysis was performed on a rectangular titanium honecomb-core sandwich panel which is subjected to thermal load with a temperature gradient across its depth. The distributions of normal stresses in the face sheets and the face-sheet/sandwich-core interfacial shear stresses are presented. The thermal buckling of the heated face sheet was analyzed by assuming the face sheet to be resting on an elastic foundation representing the sandwich core. Thermal buckling curves and thermal buckling load surface are presented for setting the limit for temperature gradient across the panel depth.

The comparison of deflections and critical failure loads were obtained by the results of the full-scale roof sandwich panels tests conducted by the company “Joris Ide” and the theoretical design, according to the calculation method described in Euronorms. Based on these results it was concluded that sandwich panels can be treated as a load-bearing structure only with more taught manufacturing requirements. Thus, the reduced spread of critical loads can be achieved.

    2015-12-01

    Full Text Available In this paper, an approach to analyze the observability and controllability of sandwich systems with backlash is proposed. In this method, a non-smooth state-space function is used to describe the sandwich systems with backlash which are also non-smooth non-linear systems. Then, a linearization method based on non-smooth optimization is proposed to derive a linearized state-space function to approximate the non-smooth sandwich systems within a bounded region around the equilibrium point that we are interested in. Afterwards, both observability and controllability matrices are constructed and the methods to analyze the observability as well as controllability of sandwich system with backlash are derived. Finally, numerical examples are presented to validate the proposed method.

    Wei, Minghai; Hu, Gang; Jin, Lu; Lin, Kun; Zou, Dujian

    2016-05-01

    The forced vibration of a sandwich beam integrating a shear thickening fluid (STF) core and with conductive skins subjected to a periodic excitation was investigated theoretically in this study. The rheological properties of the STF material including viscosity, plasticity, and elasticity may be changed under the periodic vibration, and hence they were considered. The governing equation of motion was derived based on the complex stiffness method and some key parameters were derived based on the Timoshenko beam theory. Effects of the excitation frequency, the excitation amplitude, the excitation location, and the skin/core thickness ratio on the nature frequency of the sandwich beam were investigated. It was found that the STF core has a significant effect on the dynamic property of the sandwich beam. Based on the findings, integrating the STF core in a sandwich beam can reduce the vibration of the beam.

    2013-01-01

    In the education of students who are deaf and hard of hearing (DHH), there is much debate about how placement affects educational outcomes and quality of life. This study examined the relationship between quality of life and educational placement that include and do not include other DHH youth. Participants included 221 DHH youth, ages 11-18 with bilateral hearing loss. Results showed that there were few differences in quality of life related to school placement (with age, gender, depression symptoms, and hearing level as covariates). For both participation and perceived stigma, there was an interaction between school placement and parent hearing status, with no single school placement showing the best results. DHH youth with hearing parents in schools specifically for DHH students scored lower than DHH with deaf parents in some domains (Participation and Perceived Stigma). When the DHH youth were compared with the general population, those in schools that included DHH students scored lower in some aspects of quality of life, particularly Self and Relationships. This study demonstrates that DHH students may not differ much in terms of quality of life across schools placements, but that there may be differences in subsets of DHH youth.

    Cruz, Juan R.

    1991-01-01

    An analysis and design method is presented for the design of composite sandwich cover panels that include the transverse shear effects and damage tolerance considerations. This method is incorporated into a sandwich optimization computer program entitled SANDOP. As a demonstration of its capabilities, SANDOP is used in the present study to design optimized composite sandwich cover panels for for transport aircraft wing applications. The results of this design study indicate that optimized composite sandwich cover panels have approximately the same structural efficiency as stiffened composite cover panels designed to satisfy individual constraints. The results also indicate that inplane stiffness requirements have a large effect on the weight of these composite sandwich cover panels at higher load levels. Increasing the maximum allowable strain and the upper percentage limit of the 0 degree and +/- 45 degree plies can yield significant weight savings. The results show that the structural efficiency of these optimized composite sandwich cover panels is relatively insensitive to changes in core density. Thus, core density should be chosen by criteria other than minimum weight (e.g., damage tolerance, ease of manufacture, etc.).

    The structural efficiency of compression-loaded trapezoidal-corrugation sandwich and semi-sandwich composite panels is studied to determine their weight savings potential. Sandwich panels with two identical face sheets and a trapezoidal corrugated core between them, and semi-sandwich panels with a corrugation attached to a single skin are considered. An optimization code is used to find the minimum weight designs for critical compressive load levels ranging from 3,000 to 24,000 lb/in. Graphite-thermoplastic panels based on the optimal minimum weight designs were fabricated and tested. A finite-element analysis of several test specimens was also conducted. The results of the optimization study, the finite-element analysis, and the experiments are presented.

  5. Electronically asymmetric bis(porphyrin) sandwich complexes

    Girolami, G.S.; Gorlin, P.A.; Suslick, K.S. [Univ. of Illinois, Urbana, IL (United States)

    1994-02-16

    Bis(porphyrin)metal(IV) complexes (M(porph){sub 2}) have been extensively studies in recent years due to their structural, chemical, and spectroscopic similarity to the {open_quotes}special pair{close_quotes} found in the reaction center of photosynthetic bacteria. Strong interactions arise in the bis(porphyrin) complexes due to the short inter-porphyrin separation (< 3 {angstrom}), which results in properties not seen in mono(porphyrin) analogs. For example, the bis(porphyrin) complexes are considerably easier to oxidize than analogous mono(porphyrin) species, and the M(porph){sub 2{sup n+}} cations (n = 1,2) exhibit near-IR absorptions not found in simple mono(porphyrin)cations. As part of the authors continuing effort to understand the factors that govern the electronic structures of bis(porphyrin) supermolecules, the authors now describe the synthesis of a series of zirconium sandwich complexes. Introduction of electron-withdrawing or -donating groups on the {beta}-pyrrole position considerably affects the electronic properties of these molecules without altering their steric parameters. Thus, peripheral substitution allows modification of the inter-porphyrin {pi} interactions while keeping the inter-porphyrin separation constant. Previous studies have changed the identity of the central metal, but the electronic structure and the interplanar distance could not be varied independently.

  6. Accounting for L2 learners’ errors in word stress placement

    2016-01-01

    Full Text Available Stress placement in English words is governed by highly complicated rules. Thus, assigning stress correctly in English words has been a challenging task for L2 learners, especially Indonesian learners since their L1 does not recognize such stress system. This study explores the production of English word stress by 30 university students. The method used for this study is immediate repetition task. Participants are instructed to identify the stress placement of 80 English words which are auditorily presented as stimuli and immediately repeat the words with correct stress placement. The objectives of this study are to find out whether English word stress placement is problematic for L2 learners and to investigate the phonological factors which account for these problems. Research reveals that L2 learners have different ability in producing the stress, but three-syllable words are more problematic than two-syllable words. Moreover, misplacement of stress is caused by, among others, the influence of vowel lenght and vowel height.

    The purposes of this study were to evaluate the sealing ability of different glass ionomer cements (GICs) used for sandwich restorations and to assess the effect of acid etching of GIC on microleakage at GIC-resin composite interface. Forty cavities were prepared on the proximal surfaces of 20 permanent human premolars (2 cavities per tooth), assigned to 4 groups (n=10) and restored as follows: Group CIE - conventional GIC (CI) was applied onto the axial and cervical cavity walls, allowed setting for 5 min and acid etched (E) along the cavity margins with 35% phosphoric acid for 15 s, washed for 30 s and water was blotted; the adhesive system was applied and light cured for 10 s, completing the restoration with composite resin light cured for 40 s; Group CIN - same as Group CIE, except for acid etching of the CI surface; Group RME - same as CIE, but using a resin modified GIC (RMGIC); Group RMN - same as Group RME, except for acid etching of the RMGIC surface. Specimens were soaked in 1% methylene blue dye solution at 24 degrees C for 24 h, rinsed under running water for 1 h, bisected longitudinally and dye penetration was measured following the ISO/TS 11405-2003 standard. Results were statistically analyzed by Kruskal-Wallis and chi-square tests (a=0.05). Dye penetration scores were as follow: CIE - 2.5; CIN - 2.5; RME - 0.9; and RMN - 0.6. The results suggest that phosphoric acid etching of GIC prior to the placement of composite resin does not improve the sealing ability of sandwich restorations. The RMGIC was more effective in preventing dye penetration at the GIC-resin composite-dentin interfaces than CI.

    This study discusses the process of validating a mathematics placement test at a technical university. The main objective is to produce a valid and reliable test to measure students' prerequisite knowledge to learn engineering technology mathematics. It is crucial to have a valid and reliable test as the results will be used in a critical decision making to assign students into different groups of Technical Mathematics 1. The placement test which consists of 50 mathematics questions were tested on 82 new diplomas in engineering technology students at a technical university. This study employed rasch measurement model to analyze the data through the Winsteps software. The results revealed that there are ten test questions lower than less able students' ability. Nevertheless, all the ten questions satisfied infit and outfit standard values. Thus, all the questions can be reused in the future placement test at the technical university.

    Semiconductor sandwich neutron spectrometers are suitable for in-pile measurements of fast reactor spectra thanks to their compact and relatively simple design. We have assembled and tested a sandwich neutron spectrometer based on 4H-silicon carbide (4H-SiC) Schottky diodes. The SiC diodes detect neutrons via neutron-induced charged particles (tritons and alpha particles) produced by {sup 6}Li(n,α){sup 3}H reaction. {sup 6}LiF neutron converter layers are deposited on the front surface of Schottky diodes by magnetron sputtering. The responses of SiC diodes to charged particles were investigated with an {sup 241}Am alpha source. A sandwich neutron spectrometer was assembled with two SiC Schottky diodes selected based on the charged-particle-response experimental results. The low-energy neutron response of the sandwich spectrometer was measured in the neutron field of the Chinese Fast Burst Reactor-II (CFBR-II). Spectra of alpha particles and tritons from {sup 6}Li(n,α){sup 3}H reaction were obtained with two well-resolved peaks. The energy resolution of the sum spectrum was 8.8%. The primary experimental results confirmed the 4H-SiC sandwich neutron spectrometer's feasibility. -- Highlights: ► Sandwich neutron spectrometer employing 4H-SiC as a detecting material has been developed for the first time. ► {sup 6}LiF neutron converter has been deposited on the surface of 4H-SiC Schottky diode. ► Preliminary testing results obtained with the 4H-SiC sandwich neutron spectrometer are presented.

Two students and a stakeholder involved with each project were sampled. A standardised survey was emailed to students and in-depth interviews were held with stakeholders.Results: Fifty two per cent of 64 students and 57% of 25 stakeholders responded. Most students felt that the placements enhanced their academic experience and confidence in research skills, and were an effective form of learning. Perceived challenges included time constraints and, for a minority, inadequately prepared settings and stakeholders. Stakeholders felt that the placements empowered the communities and prepared students for the realities of working as a medical professional. They viewed students as a valuable resource and believed that student projects addressed important community myths and health problems. Recommendations from students and stakeholders included more time for the Public Health block, followup interventions for greater continuity, and better alignment of projects with stakeholder programmes.Conclusion: The evaluation reveals both the importance and challenges of community placements and identifies areas of improvement. Despite the limited duration of the placements, they offered valuable community-based learning experiences for the students and worthwhile benefits for the communities.

  1. Enhancing Fatigue Performance of Sandwich Composites with Nanophased Core

    Directory of Open Access Journals (Sweden)

    S. Zainuddin

    2010-01-01

    Full Text Available We report fatigue performance of sandwich composites with nanophased core under shear load. Nanophased core was made from polyurethane foam dispersed with carbon nanofiber (CNF. CNFs were dispersed into part-A of liquid polyurethane through a sonication process and the loading of nanoparticles was 1.0 wt%. After dispersion, part-A was mixed with part-B, cast into a mold, and allowed to cure. Nanophased foam was then used to fabricate sandwich composites. Static shear tests revealed that strength and modulus of nanophased foams were 33% and 19% higher than those of unreinforced (neat foams. Next, shear fatigue tests were conducted at a frequency of 3 Hz and stress ratio (R of 0.1. S-N curves were generated and fatigue performances were compared. Number of cycles to failure for nanophased sandwich was significantly higher than that of the neat ones. For example, at 57% of ultimate shear strength, nanophased sandwich would survive 400,000 cycles more than its neat counterpart. SEM micrographs indicated stronger cell structures with nanophased foams. These stronger cells strengthened the sub-interface zones underneath the actual core-skin interface. High toughness of the sub-interface layer delayed initiation of fatigue cracks and thereby increased the fatigue life of nanophased sandwich composites.

  2. Critical velocity of sandwich cylindrical shell under moving internal pressure

    Institute of Scientific and Technical Information of China (English)

    2008-01-01

    Critical velocity of an infinite long sandwich shell under moving internal pres-sure is studied using the sandwich shell theory and elastodynamics theory. Propagation of axisymmetric free harmonic waves in the sandwich shell is studied using the sandwich shell theory by considering compressibility and transverse shear deformation of the core, and transverse shear deformation of face sheets. Based on the elastodynamics theory, displacement components expanded by Legendre polynomials, and position-dependent elastic constants and densities are introduced into the equations of motion. Critical ve-locity is the minimum phase velocity on the desperation relation curve obtained by using the two methods. Numerical examples and the finite element (FE) simulations are pre-sented. The results show that the two critical velocities agree well with each other, and two desperation relation curves agree well with each other when the wave number κ is relatively small. However, two limit phase velocities approach to the shear wave velocities of the face sheet and the core respectively when k limits to infinite. The two methods are efficient in the investigation of wave propagation in a sandwich cylindrical shell when κ is relatively small. The critical velocity predicted in the FE simulations agrees with theoretical prediction.

    Full Text Available Mechanical behaviour of sandwich panels under different conditions have been exprimentally studied in this research to increase the knowledge of aircraft sandwich panel structures and facilitate design criteria for aircraft structures. Tests were concentrated on the honeycomb sandwich structures under different loads including flexural, insert shear, flat wise tension and compression loads. Furthermore, effect of core density and face material on mechanical behavior of different samples were investigated and compared with analytical and FEM method. Effects of skin thickness on strength of honycomb sandwhich panels under shear pull out and moments have also been considerd in this study. According to this investigation, insert strength and flexural test under different load conditions is strongly affected by face thickness, but compression and tearoff (falt wise tensile properties of a sandwich panel depends on core material. The study concludes that the correlation between experimental results and the analytical predictions will enable the designer to predict the mechanical behaviour and strength of a sandwich beam; however, applied formula may lead engineers to unreliable results for shear modulus.

    The main objective of this project is to identify the test methods which provide useful results for the different types of penetrating impacts occurring in sandwich structures. A series of penetrating impact tests on FRP-sandwich panels is performed using three different test methods and the results of the test methods are compared. The test methods used are the standardised method ISO 6603 and two non-standardised methods. The first non-standardised method uses a pyramid-shaped impactor instead of the cylindrical impactor used in the ISO 6603 method. In the second non-standardised method, the impact test is performed quasistatically using a cylindrical impactor. Possible stages of failure occurring in FRP-sandwich during a penetrating impact are illustrated. A comprehensive test method should be able to provoke various failure modes, as observed in impact failures of actual sandwich structures. The results obtained with the three test methods lead to a different ranking in impact strength of the panels. Hence, impact test results obtained with different test methods are not even qualitatively comparable. The pyramid-shaped impactor is able to generate clearly more failure modes than the cylindrical impactor in the ISO 6603 method. Therefore, it is considered to be of more practical value for determining the impact strength of PRP-sandwich structures. (orig.) (15 refs.)

    Truss-core sandwich plates have received much attention in virtue of the high values of strength-to-weight and stiffness-to-weight as well as the great ability of impulse-resistance recently. It is necessary to study the stability of sandwich panels under the influence of the thermal load. However, the sandwich plates are such complex three-dimensional (3D) systems that direct analytical solutions do not exist, and the finite element method (FEM) cannot represent the relationship between structural parameters and mechanical properties well. In this paper, an equivalent homogeneous continuous plate is idealized by obtaining the effective bending and transverse shear stiffness based on the characteristics of periodically distributed unit cells. The first order shear deformation theory for plates is used to derive the stability equation. The buckling temperature of a simply supported sandwich plate is given and verified by the FEM. The effect of related parameters on mechanical properties is investigated. The geometric parameters of the unit cell are optimized to attain the maximum buckling temperature. It is shown that the optimized sandwich plate can improve the resistance to thermal buckling significantly.

    Aimed at the low noise design of sonar dome in ships, a method has been presented for calculating the sonar self noise of a simplified sonar dome consisting of sandwich acoustic window and parallel acoustic cavity, which is excited by stationary random pressure fluctuation of turbulence boundary layer, using temporal and spatial double Fourier transform and wavenumber-frequency spectrum analysis. After numerically analyzing the influence of geometrical and physical parameters of acoustic window on the sonar self noise, the design method and reasonable parameters for sandwich acoustic window are proposed. The results show that the property of low noise induced by acoustic window of sandwich is dominated by the cut-off effect of longitudinal wave and transverse wave propagating in the visco-elastic layer of sandwich as well as the mismatch effect of impedance. If the thickness, density, Young's modulus and damping factor of plates and visco-elastic layer as well as the sound speed of longitudinal wave and transverse wave in the visco-elastic layer are selected reasonably, the maximum noise reduction of sandwich acoustic window is 6.5 dB greater than that of a single glass fiber reinforced plastic plate.

    Clinical placement is a valuable component of nursing education, helping students to authenticate, integrate and develop a range of nursing skills and knowledge. The diversity of nursing curricula throughout the world and the many models of clinical placement make this a difficult subject to research using typical qualitative and quantitative research methodologies. The potential for case study methodology to address the complexity of learning in the clinical environment is significant. This paper argues that Complexity Theory provides an interpretive paradigm that articulates well with case study methodology. This paper also provides an example of the development of a theoretical proposition based on pattern matching. Pattern matching is an approach to data analysis that encourages a consideration of predicted patterns with those that are empirically based. Copyright © 2012 Elsevier Ltd. All rights reserved.

  9. Ham Sandwich with Mayo: A Stronger Conclusion to the Classical Ham Sandwich Theorem

    CERN Document Server

    Elton, John H

    2009-01-01

    The conclusion of the classical ham sandwich theorem of Banach and Steinhaus may be strengthened: there always exists a common bisecting hyperplane that touches each of the sets, that is, intersects the closure of each set. Hence, if the knife is smeared with mayonnaise, a cut can always be made so that it will not only simultaneously bisect each of the ingredients, but it will also spread mayonnaise on each. A discrete analog of this theorem says that n finite nonempty sets in n-dimensional Euclidean space can always be simultaneously bisected by a single hyperplane that contains at least one point in each set. More generally, for n compactly-supported positive finite Borel measures in Euclidean n-space, there is always a hyperplane that bisects each of the measures and intersects the support of each measure.

    2003-01-01

    The problem of nonlinear forced oscillations for elliptical sandwich plates is dealtwith. Based on the governing equations expressed in terms of five displacement components,the nonlinear dynamic equation of an elliptical sandwich plate under a harmonic force isderived. A superpositive-iterative harmonic balance ( SIHB ) method is presented for thesteady-state analysis of strongly nonlinear oscillators. In a periodic oscillation, the periodicsolutions can be expressed in the form of basic harmonics and bifurcate harmonics. Thus,an oscillation system which is described as a second order ordinary differential equation,can be expressed as fundamental differential equation with fundamental harmonics andincremental differential equation with derived harmonics. The 1/3 subharnonic solution ofan elliptical sandwich plate is investigated by using the methods of SIHB. The SIHB methodis compared with the numerical integration method. Finally, asymptotical stability of the1/3 subharmonic oscillations is inspected.

    Sandwich complexes feature unique properties as the physical and electronic properties of a hydrocarbon ligand or its derivative are integrated into the physical, electronic, magnetic, and optical properties of a metal. Incorporation of these complexes into macromolecules results in intriguing physical, electrical, and optical properties that were hitherto unknown in organic-based macromolecules. These properties are tunable through well-designed synthetic strategies. This review surveys many of the synthetic approaches that have resulted in tuning the properties of sandwich complex-containing macromolecules. While the past two decades have seen an ever-growing number of research publications in this field, gaps remain to be filled. Thus, we expect this review to stimulate research interest towards bridging these gaps, which include the insolubility of some of these macromolecules as well as expanding the scope of the sandwich complexes. © 2014 WILEY-VCH Verlag GmbH & Co.

  12. Identification of material properties of sandwich structure with piezoelectric patches

    2008-11-01

    Full Text Available The work focuses on light-weight sandwich structures made of carbon-epoxy skins and foam core which have unique bending stiffness compared to conventional materials. The skins are manufactured by vacuum autoclave technology from unidirectional prepregs and the sandwich is then glued together. The resulting material properties of the structure usually differ from those provided by manufacturer or even those obtained from experimental tests on separate materials, which makes computational models unreliable. Therefore, the properties are identified using the combination of experimental analysis of the sandwich with attached piezoelectric transducer and corresponding static and modal finite element analyses. Simple mathematical optimization with repetitive finite element solution is used. The model is then verified by transient analysis when the piezoelectric patch is excited by harmonic signals covering the first two eigen-frequencies and the induced oscillations are measured by laser sensor.

    An x-ray radiographic system consisting of two detectors in tandem, or a sandwich detector, can produce dual-energy image from a single-shot exposure. Subtraction of two images obtained from the two detectors can produce a sharper image through an unsharp masking effect if the two images are formed at different spatial resolutions. This is indeed possible by incorporating different thicknesses of x-ray conversion layers in the detectors. In this study, we have developed a microtomography system with a sandwich detector in pursuit of high-resolution bone-enhanced small-animal imaging. The results show that the bone-enhanced images reconstructed from the dual-energy projection data provide higher visibility of bone details than the conventionally reconstructed images. The microtomography with the single-shot dual-energy sandwich detector will be useful for the high-resolution bone-enhanced small-animal imaging.

    This paper presents the free vibration analysis of sandwich plates with cutouts. Cutouts are inevitable in structural applications and the presence of these cutouts in the structures greatly influences their dynamic characteristics. A finite element model has been developed here using the ANSYS 15.0 software to study the free vibration characteristics of sandwich plates in the presence of cutouts. Shell 281 element, an 8-noded element with six degrees of freedom suited for analyzing thin to moderately thick structures is considered in the development of the model. Block Lanczose method is adopted to extract the mode shapes to obtain the natural frequency corresponding to free vibration of the plate. The effects of parametric variation on the natural frequency of the sandwich plates with cutout are studied and results are presented.

    Void is the most common tiny defect of composite materials. Porosity is closely related to composite structure property. The voids forming behaviour in the composites sandwich structural parts with the carbon fiber reinforced epoxy resin skins was researched by adjusting the manufacturing process parameters. The composites laminate with different porosities were prepared with the different process parameter. The ultrasonic non-destructive measurement method for the porosity was developed and verified through microscopic examination. The analysis results show that compaction pressure during the manufacturing process had influence on the porosity in the laminate area. Increasing the compaction pressure and compaction time will reduce the porosity of the laminates. The bond-line between honeycomb core and carbon fiber reinforced epoxy resin skins were also analyzed through microscopic examination. The mechanical properties of sandwich structure composites were studied. The optimization process parameters and porosity ultrasonic measurement method for composites sandwich structure have been applied to the production of the composite parts.

    The air-coupled ultrasonic techniques have been improved drastically in recent years. Better equipment has made this technique much more useful. This paper focuses on the examination of sandwich materials used in naval ships. It is more convenient to be able to make the measurements directly...... in atmospheric air instead of using immersion technique. The air-coupled techniques have been used in through-transmission mode using separate sender and receiver transducer. The frequency was either 50 kHz or 120 kHz. Laboratory tests on glass fibre/PVC foam core sandwich panels showed that debonds between core...... and skin laminate could be found by the air-coupled technique. It was therefore decided to use this technique in-situ during mechanical testing of sandwich panels.

    2017-09-01

    A theoretical study has been carried out on sandwich beams strengthened mechanically by two external steel plates attached to their tension and compression sides with so-called "shear connectors ". This study is based on the individual behaviour of each component of the composite sandwich section (i.e. reinforced concrete beam and upper steel plate and lower steel plate). The approach has been developed to simulate the behaviour of such beams, and is based on neglecting the separation between the three layers; i.e., the deflections are equal in each element through the same section. The differential equations reached were solved analytically. Deflection was calculated by using the approach for several beams, tested in two series, and close agreements were obtained with the experimental values. Furthermore, the interaction efficiency between the three elements in a composite sandwich beam has been considered thoroughly, from which the effect of some parameters, such as plate length upon the behaviour of such beams, were studied.

    Honda, S.; Narita, Y.

    2016-09-01

    The present paper develops a shell element based on the refined zigzag theory (RZT) and applies it to the vibration analysis and optimization problem of the composite sandwich plate composed of CFRP skins and soft-cores. The RZT accepts large differences in layer stiffness, and requires less calculation effort than the layer-wise or three-dimensional theories. Numerical results revealed that the present method predicts vibration characteristics of composite sandwich plates with soft-core accurately. Then, shapes of reinforcing fibers in CFRP composite skins are optimized to maximize fundamental frequencies. As an optimizer, the particle swarm optimization (PSO) approach is employed since curvilinear fiber shapes are defined by continuous design variables. Obtained results showed that the composite sandwich with optimum curvilinear fiber shapes indicates higher fundamental frequencies compared with straight fibers.

    2016-02-01

    Bending analysis of a sandwich beam with soft core and carbon nanotube reinforced composite (CNTRC) face sheets in the literature is presented based on Extended High order Sandwich Panel Theory (EHSAPT). Distribution of fibers through the thickness of the face sheets could be uniform or functionally graded (FG). In this theory the face sheets follow the first order shear deformation theory (FSDT). Besides, the two dimensional elasticity is used for the core. The field equations are derived via the Ritz based solution which is suitable for any essential boundary condition. The influences of boundary conditions on bending response of the sandwich panel with soft core and CNTRC face sheet are investigated. In each type of boundary condition the effect of distribution pattern of CNTRCs on many essential involved parameters of the sandwich beam with functionally graded carbon nanotube reinforced composite (FG- CNTRC) face sheets are studied in detail. Finally, experimental result have been compared with those obtained based on developed solution method. It is concluded that, the sandwich beam with X distribution figure of face sheets is the strongest with the smallest transverse displacement, and followed by the UD, O and ∧-ones, respectively.

    The proportion of eighth graders in United States public schools enrolled in algebra or a more advanced mathematics course doubled between 1990 and 2011. This article uses Early Childhood Longitudinal Study's Kindergarten Cohort data to consider the selection process into advanced middle school mathematics courses and estimate the effects of advanced courses on students' mathematics achievement (n = 6,425; mean age at eighth grade = 13.7). Eighth-grade algebra and geometry course placements are academically selective, but considerable between-school variation exists in students' odds of taking these advanced courses. While analyses indicate that advanced middle school mathematics courses boost student achievement, these effects are most pronounced in content areas closely related to class content and may be contingent on student academic readiness. © 2014 The Author.

    Based on yon Karman plate theory, the issue about nonlinear vibration for circular sandwich plates under circumjacent load with the loosely clamped boundary condition was researched. Nonlinear differential eigenvalue equations and boundary conditions of the problem were formulated by variational method and then their exact static solution can be got. The solution was derived by modified iteration method, so the anslytic relations between amplitude and nonlinear oscillating frequency for circular sandwich plates were obtained. When circumjacent load makes the lowest natural frequency zero,critical load is obtained.

    There is a strong interest in economical methods for hydrogen separation. In this work, we have developed sandwiched membranes, Pd-Ag/V-15Ni/Pd-Ag, which had much lower environmental impact than palladium-based membranes, which are the most commonly used membrane for the current production of highly pure hydrogen. The Pd-Ag overlayer was prepared on V-15Ni substrates (thickness 40 {mu}m) using multi-target sputtering. The hydrogen permeation of the Pd-Ag/V-15Ni/Pd-Ag sandwiched membranes was examined using gas permeation technology. (orig.)

    This study proposes a novel process for fabricating a sandwiched long-period fiber grating (SLPFG) using a SU-8 thick photoresist technique. The SLPFG consists of a thin cladding optical fiber sandwiched with a double-sided periodical grating coating. By varying the external loads on the SLPFG, the transmission dip of the resonance wavelength is tuned according to a squared-harmonic curve. The SLPFG can thus be utilized as a loss tunable filter or sensor. The resonance dip wavelength is related to the cladding thicknesses of the optical fiber and the periods of the grating. A maximum transmission resonant dip of 34.61dB was achieved.

    2013-12-01

    The increase of the base transceiver station (BTS) in most urban areas can be traced to the drive by network providers to meet demand for coverage and capacity. In traditional network planning, the final decision of BTS placement is taken by a team of radio planners, this decision is not fool proof against regulatory requirements. In this paper, an intelligent based algorithm for optimal BTS site placement has been proposed. The proposed technique takes into consideration neighbour and regulation considerations objectively while determining cell site. The application will lead to a quantitatively unbiased evaluated decision making process in BTS placement. An experimental data of a 2km by 3km territory was simulated for testing the new algorithm, results obtained show a 100% performance of the neighbour constrained algorithm in BTS placement optimization. Results on the application of GA with neighbourhood constraint indicate that the choices of location can be unbiased and optimization of facility placement for network design can be carried out.

    2000-01-01

    This research investigated genetic algorithm approaches for smart actuator placement to provide aircraft maneuverability without requiring hinged flaps or other control surfaces. The effort supported goals of the Multidisciplinary Design Optimization focus efforts in NASA's Aircraft au program. This work helped to properly identify various aspects of the genetic algorithm operators and parameters that allow for placement of discrete control actuators/effectors. An improved problem definition, including better definition of the objective function and constraints, resulted from this research effort. The work conducted for this research used a geometrically simple wing model; however, an increasing number of potential actuator placement locations were incorporated to illustrate the ability of the GA to determine promising actuator placement arrangements. This effort's major result is a useful genetic algorithm-based approach to assist in the discrete actuator/effector placement problem.

    Brodnick, D

    2000-01-01

    A new method uses redundancy in the 12-lead electrocardiogram (ECG) to determine the angles to all of the electrodes used to record the ECG. No other transducers or signals are needed. The method, a matrix manipulation of the standard 12-lead, would be applicable to all existing ECGs already stored on hospital systems. The invention of this method was originally motivated by the slight differences seen between ECGs acquired by the standard resting electrode placement versus those acquired in a monitoring or exercise placement. An ECG signal is acquired in multiple channels. A covariance matrix is formed. From the eigenvector solution of the matrix, the angles between the eigenvectors and the original signal vectors are determined. The angles calculated for any ECG test are compared to reference angles to determine whether the electrodes are placed in the standard ECG electrode placement, an alternative electrode placement, or an incorrect electrode placement.

    The objective of this study was to describe the selected conditions for school achievement of students with mild intellectual disabilities from Polish elementary schools. Participants were 605 students with mild disabilities from integrative, regular, and special schools, and their parents (N=429). It was found that socioeconomic status (SES) was positively associated with child placement in integrative and regular schools rather than special schools, as well as with higher parental engagement in their children's studies. Parental engagement mediated the positive effects of SES and placement in regular and integrative schools on school achievement. The results are discussed in the context of inclusive education theory.

    Full Text Available With competition becoming ever fiercer, brands must conform to modern marketing and become more influential on consumer perceptions by developing strategies according to the needs and demands of consumers. Hence it is very important to determine how the br and is perceived and placed in the consumer’s mind. Branding is a key issue on the modern agenda. As universities have understood the importance of establishing corporate identity and brand placement, they have joined the race and begun developing social strategies to develop their brand values. These include establishing brand belongingness, advertising and promotions and efforts to make the university stand out among similar ones. Brand placement in the minds of users is attempted through the name, logo , colors, characters and fonts representing the university used on clothing, office material and similar. Brand placement efforts include definitions by consumers of the product or service or attempts to distinguish these from those of competitors. This r esearch deals with a clothing b rand representing a university, brand image and product perceptions as well as the brand placement efforts. The scanning method was used in the research. The brand of casual clothing used as an example for brand placement as well as similarly known brands were examined for their product variety, prices and consumer portfolios. Measurement devices were prepared for the brand placement of the apparel designed and produced for the university, and a pilot trial was performed. I n the pilot trial, a set of questions was asked to a group of randomly chosen 242 people, consisting of academics, university students and administrative staff. The data obta ined were analyzed using SPSS 16 .0. Findings were given in tables according to sta tus variables. The finding of the research indicate that in brand placing efforts, for the intended consumer the apparel’s fabric, stitching and print/embroidery quality, its price

    Teaching high school students about the digestive system can be a challenge for a teacher when s/he wants to overcome rote learning of facts without a deeper understanding of the physiological processes inside the alimentary tract. A series of model experiments illustrating the journey of a sandwich was introduced into teaching high school biology. Using a computer equipped with a commercially available data-acquisition system and a couple of sensors, it was possible to illustrate the basic underlying physical and chemical principles of digestion to the students. Students were able to investigate, through hands-on activities, the chewing force of the jaws, importance of the mechanical breakdown of food, enzymatic activity of pepsin and amylase, antibacterial activity of hydrochloric acid, and importance of the villi for absorption. Students found the experiments interesting and helpful for understanding the digestive process. Furthermore, the results from testing indicated that the students had a deeper understanding of the physiological processes.

    2005-05-01

    Full Text Available Bending and deformation of sandwich panels due to localized pressure were analyzed using both Rayleigh-Ritz and finite element methods. The faces were made of laminated composite plates, while the core was a honeycomb material. Carbon fiber and glass fiber reinforced plastics were used for composite plate faces. In the case of Rayleigh-Ritz method, first the total energy of the system was calculated and then taking the variations of the total energy, the sandwich panel deflections could be computed. The deflections were assumed by means of Fourier series. A finite element code NASTRAN was exploited extensively in the finite element method. 3-dimensional 8-node brick elements were used to model sandwich panels, for both the faces sheets and the core. The results were then compared to each other and in general they are in good agreements. Dimple phenomena were found in these cases. It shows that localized pressure on sandwich structures will produce dimple on the pressurize region with little effects on the rest of the structures.

    The lattice core sandwich structures have drawn more attention for the integration of load capacity and multifunctional applications. However, the connection of carbon fibers reinforced polymer composite (CFRP) lattice core sandwich structure hinders its application. In this paper, a typical connection of two lattice core sandwich panels, named as corner joint or L-joint, was investigated by experiment and finite element method (FEM). The mechanical behavior and failure mode of the corner joints were discussed. The results showed that the main deformation pattern and failure mode of the lattice core sandwich bolted corner joints structure were the deformation of metal connector and indentation of the face sheet in the bolt holes. The metal connectors played an important role in bolted corner joints structure. In order to save the calculation resource, a continuum model of pyramid lattice core was used to replace the exact structure. The computation results were consistent with experiment, and the maximum error was 19%. The FEM demonstrated the deflection process of the bolted corner joints structure visually. So the simplified FEM can be used for further analysis of the bolted corner joints structure in engineering.

    Sandwich composite material possesses advantages of both light weight and high strength.Although the mechanical behaviors of sandwich composite material with the influence of single external environment have been intensively studied,little work has been done in the study of mechanical property,in view of the nonlinear behavior of sandwich composites in the complicated external environments.In this paper,the problem about the bending of the three-layer elastic-plastic rod located on the elastic base,with a compressibly physical nonlinear core,has been studied.The mechanical response of the designed three-layer elements consisting of two bearing layers and a core has been examined.The complicated problem about curving of the three-layer rod located on the elastic base has been solved.The convergence of the proposed method of elastic solutions is examined to convince that the solution is acceptable.The calculated results indicate that the plasticity and physical nonlinearity of materials have a great influence on the deformation of the sandwich rod on the elastic basis.

    We demonstrate a sandwich configuration for microfluidic manipulation in LiNbO3 platform based on photovoltaic effect, and the behaviours of dielectric microdroplet under this sandwich configuration are investigated. It is found that the microdroplet can generate in the form of liquid bridge inside the LiNbO3-based sandwich structure under the governing dielectrophoretic force, and the dynamic process of microdroplet generation highly depends on the substrate combinations. Dynamic features found for different combinations are explained by the different electrostatic field distribution basing on the finite-element simulation results. Moreover, the electrostatic field required by the microdroplet generation is estimated through meniscus evolution and it is found in good agreement with the simulated electrostatic field inside the sandwich gap. Several kinds of microdroplet manipulations are attempted in this work. We suggest that the local dielectrophoretic force acting on the microdroplet depends on the distribution of the accumulated irradiation dosage. Without using any additional pumping or jetting actuator, the microdroplet can be step-moved, deformed or patterned by the inconsecutive dot-irradiation scheme, as well as elastically stretched out and back or smoothly guided in a designed pass by the consecutive line-irradiation scheme.

    2001-01-01

    A nonlinear finite element analysis was performed to simulate axial compression of sandwich beams with debonded face sheets. The load - end-shortening diagrams were generated for a variety of specimens used in a previous experimental study. The energy release rate at the crack tip was computed using the J-integral, and plotted as a function of the load. A detailed stress analysis was performed and the critical stresses in the face sheet and the core were computed. The core was also modeled as an isotropic elastic-perfectly plastic material and a nonlinear post buckling analysis was performed. A Graeco-Latin factorial plan was used to study the effects of debond length, face sheet and core thicknesses, and core density on the load carrying capacity of the sandwich composite. It has been found that a linear buckling analysis is inadequate in determining the maximum load a debonded sandwich beam can carry. A nonlinear post-buckling analysis combined with an elastoplastic model of the core is required to predict the compression behavior of debonded sandwich beams.

This paper theoretically calculates the bending behavior of sandwich panel. The recent need to develop a new range of materials has resulted in the development of high performance lightweight composites with excellent properties. Metal– composite systems consist of alternating layers of metal and fiber-reinforced polymer composites which are bonded by an adhesive. Sandwich beams were tested under Air Bending. Stress-strain and stress-displacement were recorded by using AIMIL UTM. The beam face sheets exhibited a softening non-linearity on the bending side. Experimental results were in good agreement with predictions from simple models. On an overall basis, the sandwich panel exhibited better bending moment performance than the monolithic galvanized iron

    Directory of Open Access Journals (Sweden)

    Yu. I. Dimitrienko

    2014-01-01

    Full Text Available The paper presents a developed multi-scale model of sandwich honeycomb structures. The model allows us both to calculate effective elastic-strength characteristics of honeycomb and forced covering of sandwich, and to find a 3D stress-strain state of structures using the threedimensional elastic theory for non- homogeneous media. On the basis of finite element analysis it is shown, that under four-point bending the maximal value of bending and shear stresses in the sandwich honeycomb structures are realized in the zone of applied force and plate support. Here the local stress maxima approximately 2-3 times exceed the “engineering” theoretical plate values of bending and shear stresses in the middle of panel. It is established that at tests for fourpoint bending there is a failure of the honeycomb sandwich panels because of the local adhesion failure rather than because of the covering exfoliation off the honeycomb core in the middle of panel.

    Sandwich panels are a good option as building materials, as they offer excellent characteristics in a modular system. The goal of this study was to demonstrate the feasibility of using the microencapsulated PCM (Micronal BASF) in sandwich panels to increase their thermal inertia and to reduce the energy demand of the final buildings. In this paper, to manufacture the sandwich panel with microencapsulated PCM three different methods were tested. In case 1, the PCM was added mixing the microencapsulated PCM with one of the components of the polyurethane. In the other two cases, the PCM was added either a step before (case 2) or a step after (case 3) to the addition of the polyurethane to the metal sheets. The results show that in case 1 the effect of PCM was overlapped by a possible increase in thermal conductivity, but an increase of thermal inertia was found in case 3. In case 2, different results were obtained due to the poor distribution of the PCM. Some samples showed the effect of the PCM (higher thermal inertia), and other samples results were similar to the conventional sandwich panel. In both cases (2 and 3), it is required to industrialize the process to improve the results. (author)

    2009-01-01

    Full Text Available Surface contact explosion experiments were performed to study the dynamic behaviour of concrete sandwich panel subjected to blast loading. Experimental results have shown that there are four damage modes explosion cratering, scabbing of the backside, radial cracking induced failure, and circumferential cracking induced failure. It also illustrates that different foam materials sandwiched in the multi-layered medium have an important effect on damage patterns. Due to the foam material, the stress peak decreases one order of magnitude and the duration is more than four times that of the panel without the soft layer by numerical simulation. Additionally, the multi layered medium with concrete foam demonstrates the favourable protective property compared with that of aluminum foam. Meanwhile, the optimal analysis of the thickness of the foam material in the sandwich panel was performed in terms of experimental and numerical analyseis. The proper thickness proportion of soft layer is about 20 percent to the total thickness of sandwich panel under the conditions in this study.Defence Science Journal, 2009, 59(1, pp.22-29, DOI:http://dx.doi.org/10.14429/dsj.59.1480

    The flexural behaviour of the functionally graded sandwich spherical panel under uniform thermal environment has been investigated in the present work. The face sheets of the sandwich structure are made by the functionally graded carbon nanotube reinforced material and the core face is made by the isotropic and homogeneous material. The material properties of both the fiber and matrix are assumed to be temperature dependent. The sandwich panel model is developed in the framework of the first order shear deformation theory and the governing equation of motion is derived using the variational principle. For the discretization purpose a suitable shell element has been employed from the ANSYS library and the responses are computed using a parametric design language (APDL) coding. The performance and accuracy of the developed model has been established through the convergence and validation by comparing the obtained results with previously published results. Finally, the influence of different geometrical parameters and material properties on the flexural behaviour of the sandwich spherical panel in thermal environment has been investigated through various numerical illustrations and discussed in details.

    1992-01-01

    A composite sandwich panel consisting of carbon fiber-reinforced plastic (CFRP) skins and a syntactic foam core was selected as an appropriate structural concept for the design of wind tunnel compressor blades. Interleaving of the core with tough interlayers was done to prevent core cracking and to improve damage tolerance of the sandwich. Simply supported sandwich beam specimens were subjected to low-velocity drop-weight impacts as well as high velocity ballistic impacts. The performance of the interleaved core sandwich panels was characterized by localized skin damage and minor cracking of the core. Residual compressive strength (RCS) of the skin, which was derived from flexural test, shows the expected trend of decreasing with increasing size of the damage, impact energy, and velocity. In the case of skin damage, RCS values of around 50 percent of the virgin interleaved reference were obtained at the upper impact energy range. Based on the similarity between low-velocity and ballistic-impact effects, it was concluded that impact energy is the main variable controlling damage and residual strength, where as velocity plays a minor role.

    This project is concerned with the fabrication and flexural testing of aluminium honey comb sandwich structure which is a special case of composite materials that is fabricated by attaching two thin but stiff skins to a light weight but thick core. The core material is normally low density material but its high thickness provide the sandwich composite with high bonding stiffness. Honeycomb core are classified into two types based on the materials and structures. Hexagonal shape has a unique properties i.e has more bonding strength and less formation time based on the cell size and sheet thickness. Sandwich structure exhibit different properties such as high load bearing capacity at low weight and has excellent thermal insulation. By considering the above properties it has tendency to minimize the structural problem. So honey comb sandwich structure is choosed. The core structure has a different applications such as aircraft, ship interiors, construction industries. As there is no proper research on strength characteristics of sandwich structure. So, we use light weight material to desire the strength. There are different parameters involved in this structure i.e cell size, sheet thickness and core height. In this project we considered 3 level of comparison among the 3 different parameters cell size of 4, 6 and 8 mm, sheet thickness of 0.3, 0.5 and 0.7 mm, and core height of 20,25 and 30 mm. In order to reduce the number of experiment we use taguchi design of experiment, and we select the L8 orthogonal array is the best array for this type of situation, which clearly identifies the parameters by independent of material weight to support this we add the minitab software, to identify the main effective plots and regression equation which involves the individual response and corresponding parameters. Aluminium material is used for the fabrication of Honeycomb sandwich structure among the various grades of aluminium we consider the AL6061 which is light weight material

    Despite growing awareness of the benefits of interprofessional education and interprofessional collaboration (IPC), understanding how teams successfully transition to IPC is limited. Student exposure to interprofessional teams fosters the learners' integration and application of classroom-based interprofessional theory to practice. A further benefit might be reinforcing the value of IPC to members of the mentoring team and strengthening their IPC. The research question for this study was: Does training in IPC and clinical team facilitation and mentorship of pre-licensure learners during interprofessional clinical placements improve the mentoring teams' collaborative working relationships compared to control teams? Statistical analyses included repeated time analysis multivariate analysis of variance (MANOVA). Teams on four clinical units participated in the project. Impact on intervention teams pre- versus post-interprofessional clinical placement was modest with only the Cost of Team score of the Attitudes Towards Healthcare Team Scale improving relative to controls (p = 0.059) although reflective evaluations by intervention team members noted many perceived benefits of interprofessional clinical placements. The significantly higher group scores for control teams (geriatric and palliative care) on three of four subscales of the Assessment of Interprofessional Team Collaboration Scale underscore our need to better understand the unique features within geriatric and palliative care settings that foster superior IPC and to recognise that the transition to IPC likely requires a more diverse intervention than the interprofessional clinical placement experience implemented in this study. More recently, it is encouraging to see the development of innovative tools that use an evidence-based, multi-dimensional approach to support teams in their transition to IPC.

    AIM: To explore the methods of hepatocytes culture in a collagen gel mixture or between double layers of collagen sandwich configuration and to examine the functional and cytomorphological characteristics of cultured hepatocytes.METHODS: A two-step collagenase perfusion technique was used to isolate the hepatocytes from Wistar rats or newborn Chinese experimental piglets. The isolated hepatocytes were cultured in a collagen gel mixture or between double layers of collagen sandwich configuration respectively. The former was that rat hepatocytes were mixed with type I rat tail collagen solution till gelled, and the medium was added onto the gel. The latter was that swine hepatocytes were seeded on a plate precoated with collagen gel for 24 h, then another layer of collagen gel was overlaid, resulting in a sandwich configuration. The cytomorphological characteristics, albumin secretion, and LDH-release of the hepatocytes cultured in these two models were examined.RESULTS: Freshly isolated rat hepatocytes were successfully mixed and fixed in collagen gel, and cultured in the gel condition. During the culture period, the urea synthesized and secreted by rat hepatocytes was detected throughout the period. Likewise, newborn experimental piglet hepatocytes were successfully fixed between the double layers of collagen gel, forming a sandwich configuration.Within a week of culture, the albumin secreted by swine hepatocytes was detected by SDS/PAGE analysis. The typical cytomorphological characteristics of the hepatocytes cultured by the above two culture models were found under a phasecontrast microscope. There was little LDH-release during the culture period.CONCLUSION: Both collagen gel mixture and double layers of collagen sandwich configuration can provide cultural conditions much closer to in vivoenvironment, and are helpful for maintaining specific hepatic fiJnctions and cytomorphological characteristics. A collagen gel mixture culture may be more eligible for the

    Active sandwich-like multilayer detectors have been developed, and their potential for motion-artifact-free dual-energy x-ray imaging at a single exposure has been demonstrated in the material decomposition context. Since the sandwich detector uses the x-ray beam transmittance through the front layer, direct x-ray interaction within photodiodes in the front layer is unavoidable, and which can increase noise in the front detector images. Similar direct x-ray interaction can also occur in the rear detector layer. To obtain a better contrast performance, an additional filter layer can be placed between the two detector layers. However, this filter layer can increase adversely noise in images obtained from the rear detector layer by reducing the number of x-ray photons reaching it. A theoretical model, which can describe the signal-to-noise performance of the sandwich detector as functions of various design parameters, has been developed by using a linear cascaded-systems theory. From the cascaded-systems analysis, the direct x-ray interaction increases noise at the high spatial frequencies where the number of secondary quanta lessens. The intermediate filter layer enhances the contribution of additive electronic noise in the overall noise performance of the rear detector layer. The detailed cascaded-systems analysis on the x-ray sandwich detectors are reported in comparisons with the measured noise-power spectra and detective quantum efficiencies. The developed model will be useful for a better design and practical use of a sandwich detector for single-shot dual-energy imaging.

    Further research on cost-effective techniques to verify enteral tube placement is warranted using a variety of pediatric populations with differing conditions that may impact gastric pH. It is imperative that clinical facilities review current policies and procedures to ensure that evidence-based findings are guiding nursing practice. Many nurses continue to rely on auscultation to verify NGT placement. Education and competency validation can assist with current practices for NGT placement being consistently incorporated by all personnel in the health care setting. Continuing to search for evidence related to nursing care will guide the direct care RN in providing best practice.

    The mechanical performance of an all-composite pyramidal lattice truss core sandwich structure was investigated both theoretically and experimentally. Sandwich structures were fabricated with a hot compression molding method using carbon fiber reinforced composite T700/3234. The out-of-plane compression and shear tests were conducted. Experimental results showed that the all-composite pyramidal lattice truss core sandwich structures were more weight efficient than other metallic lattice truss core sandwich structures. Failure modes revealed that node rupture dominated the mechanical behavior of sandwich structures.

    The paper concerns the elastic buckling behavior of a newly developed superplastically formed/diffusion-bonded (SPF/DB) orthogonally corrugated core sandwich plate. Uniaxial buckling loads were calculated for this type of sandwich plate with simply supported edges by using orthotropic sandwich plate theory. The buckling behavior of this sandwich plate was then compared with that of an SPF/DB unidirectionally corrugated core sandwich plate under conditions of equal structural density. It was found that the buckling load for the former was considerably higher than that of the latter.

  4. Compressive and shear buckling analysis of metal matrix composite sandwich panels under different thermal environments

    Combined inplane compressive and shear buckling analysis was conducted on flat rectangular sandwich panels using the Raleigh-Ritz minimum energy method with a consideration of transverse shear effect of the sandwich core. The sandwich panels were fabricated with titanium honeycomb core and laminated metal matrix composite face sheets. The results show that slightly slender (along unidirectional compressive loading axis) rectangular sandwich panels have the most desirable stiffness-to-weight ratios for aerospace structural applications; the degradation of buckling strength of sandwich panels with rising temperature is faster in shear than in compression; and the fiber orientation of the face sheets for optimum combined-load buckling strength of sandwich panels is a strong function of both loading condition and panel aspect ratio. Under the same specific weight and panel aspect ratio, a sandwich panel with metal matrix composite face sheets has much higher buckling strength than one having monolithic face sheets.

    An outbreak of Salmonella indiana infection in December 2000 affected 17 staff, relatives and patients at an acute NHS Hospital in Swansea. Epidemiological investigation identified egg mayonnaise sandwiches as the vehicle of infection. It was not possible to definitively determine the source of the infection or how the prepared sandwiches became contaminated. The most likely explanation was a pasteurisation failure of a batch of the egg roll used to make these sandwiches. Sandwiches are the most frequently identified vehicle of infection in foodborne outbreaks of salmonella infection in hospitals in England and Wales. The process of sandwich preparation has inherent risks because it involves considerable handling of food, which is consumed without further cooking. Care is required in all stages of preparation including the sourcing of materials used to produce the sandwiches. NHS Trusts should review their Hazard Analysis Critical Control Point plans for sandwich production.

    2012-12-01

    The aim of this study was to develop quality clinical placements in residential aged care facilities for undergraduate nursing students undertaking their nursing practicum topics. The proportion of people aged over 65 years is expected to increase steadily from 13% in 2006 to 26% of the total population in Australia in 2051. However, when demand is increasing for a nursing workforce competent in the care of older people, studies have shown that nursing students generally lack interest in working with older people. The lack of exposure of nursing students to quality clinical placements is one of the key factors contributing to this situation. Critical action research built on a partnership between an Australian university and five aged care organisations was utilised. A theoretical framework informed by Habermas' communicative action theory was utilised to guide the action research. Multiple research activities were used to support collaborative critical reflection and inform actions throughout the action research. Clinical placements in eight residential aged care facilities were developed to support 179 nursing students across three year-levels to complete their practicum topics. Findings were presented in three categories described as structures developed to govern clinical placement, learning and teaching in residential aged care facilities.

    2007-01-01

    Anticipating the looming crisis in access to dental services in rural and remote areas, the Western Australian Centre for Rural and Remote Oral Health developed an undergraduate rural placement program to provide dental students of The University of Western Australia opportunities for direct experience of rural and remote practice during the final year of the undergraduate curriculum. The Rural, Remote and Indigenous Placement program started in 2002 and, to the end of 2005, had placed 78 final year dental students in supervised clinical practice in rural, remote or Indigenous practice. In this study, the evolution of the program (2002-2005) is described and student evaluation of the program is reported. While involved in the rural placement program, students were assessed by experienced dental practitioners and provided program evaluation. This structured feedback allowed continuous improvement of the program. Data from each year's graduates was also analysed to examine the question of influence of placements on practice location during the first 6 months after graduation. Although it will be many years before the effects of outplacement programs can be specifically attained, the evidence to date indicates that the program may be a valuable tool among the plethora of strategies being investigated to augment Australia's rural oral health workforce.

    To determine whether recruitment of rural students and uptake of extended rural placements are associated with students' expressed intentions to undertake rural internships and students' acceptance of rural internships after finishing medical school, and to compare any associations. Longitudinal study of three successive cohorts (commencing 2005, 2006, 2007) of medical students in the Sydney Medical Program (SMP), University of Sydney, New South Wales, using responses to self-administered questionnaires upon entry to and exit from the Sydney Medical School and data recorded in rolls. Students' expressed intentions to undertake rural internships, and their acceptance of rural internships after finishing medical school. Data from 448 students were included. The proportion of students preferring a rural career dropped from 20.7% (79/382) to 12.5% (54/433) between entry into and exit from the SMP. A total of 98 students took extended rural placements. Ultimately, 8.1% (35/434) accepted a rural internship, although 14.5% (60/415) had indicated a first preference for a rural post. Students who had undertaken an extended rural placement were more than three times as likely as those with rural backgrounds to express a first preference for a rural internship (23.9% v 7.7%; χ(2) = 7.04; P = 0.008) and more than twice as likely to accept a rural internship (21.3% v 9.9%; χ(2) = 3.85; P = 0.05). For the three cohorts studied, rural clinical training through extended placements in rural clinical schools had a stronger association than rural background with a preference for, and acceptance of, rural internship.

  18. Impact load mitigation in sandwich beams using local resonators

    Sharma, B

    2015-01-01

    Dynamic response of sandwich beams with resonators embedded in the cores subjected to impact loads is studied. Using finite element models the effectiveness of various local resonator frequencies under a given impact load is compared to the behavior of an equivalent mass beam. It is shown that addition of appropriately chosen local resonators into the sandwich beam is an effective method of improving its flexural bending behavior under impact loads. The effect of a given local resonance frequency under different impact load durations is also studied. It is demonstrated that the choice of appropriate local resonance frequency depends on the impact duration. Further, by performing transverse impact experiments, the finite element models are verified and the advantage of using internal resonators under impact loading conditions is demonstrated.

  19. Preserving entanglement under decoherence and sandwiching all separable states

    Lockhart, R B; Lockhart, Robert; Steiner, Michael

    2000-01-01

    Every entangled state can be perturbed, for instance by decoherence, and stay entangled. For a large class of pure entangled states, we show how large the perturbation can be. Our class includes all pure bipartite and all maximally entangled states. For an entangled state, E, the constucted neighborhood of entangled states is the region outside two parallel hyperplanes, which sandwich the set of all separable states. The states for which these neighborhoods are largest are the maximally entangled ones. As the number of particles, or the dimensions of the Hilbert spaces for two of the particles increases, the distance between two of the hyperplanes which sandwich the separable states goes to zero. It is easy to decide if a state Q is in the neighborhood of entangled states we construct for an entangled state E. One merely has to check if the trace of EQ is greater than a constant which depends upon E and which we determine.

    2017-02-01

    In this work, eco-friendly natural fabric sandwich laminate (NFSL) composites are formulated using jute and linen-fabric-reinforced epoxy with different layer ratios (5:0, 4:1, 3:2, 2:3, 1:4 and 0:5) by hand layup system. Different mechanical attributes (tensile, flexural and impact) of the NFSL composites are quantified. Thermal stability and water absorption behaviour of the NFSL composites are also assessed. A scanning electron microscope (SEM) and optical microscope are used for qualitative analysis of NFSL composites’ interfacial properties. Two layers of jute and three layers of linen sandwich laminate have registered peak values in tensile and impact properties. The five layers of linen laminate composite have exhibited high flexural strength, been proven to have good thermal stability and furthermore shown better water absorption behaviour than any other laminate composites.
