Reconsidering nutrition science: critical reflection with a cultural lens.

PubMed

Hassel, Craig A

2014-05-02

European culture gave birth to modern science as a means to investigate and explain the natural world. The biomedical disciplines that have since emerged, including nutrition, presuppose a web of basic presuppositions, background assumptions and implicit cultural values that are often overlooked and escape peer review. These "hidden subjectivities" are widely taken-for-granted while exerting a powerful hold on the scope, direction and patterns of disciplinary thought. Nutrition science currently has no accepted means of collectively attending to hidden subjectivities embedded within its methods and practice. Here I propose that directing inquiry into these dimensions holds potential to advance our discipline. This critically reflective approach emerged from critical theory and the practice of cross-cultural engagement (CCE). CCE deliberately seeks out and critically engages food and health understandings of non-European cultures. Its protocol includes cognitive frameshifting, a practice of temporarily stepping outside of habitual thought patterns and into a non-biomedical framework of background assumptions. A cultural lens metaphor derives from CCE practice and is forwarded here as a viable means for restoring critically reflective attention to hidden subjectivities while also inviting further CCE practice within the discipline. Critical reflection with a cultural lens allows cognitive attachments to materialism, reductionism, mechanistic thought, naïve realism, control over nature and pervasive subject-object dichotomies between mind and matter, scientist and nature, experience and reality, among many others to become more available for critical consideration. Culturally diverse food and health understandings otherwise dismissed as "unscientific" or held in abeyance gain value as alternative assumptive frameworks and cognitive models that can be temporarily inhabited for further intercultural reflection and insight.

The Men's INTernet Study II included a randomized controlled trial to develop and test an Internet-based HIV prevention intervention for U.S men who use the Internet to seek sex with men. In 2008, participants (n = 560) were randomized to an online, interactive, sexual risk-reduction intervention or to a wait list null control. After 3 months, participants in both conditions reported varying degrees of change in sexual beliefs or behaviors. Using content analysis and logistic regression, this mixed-methods study sought to understand why these changes occurred. Level of critical self-reflection of assumptions appeared to facilitate the labeling of sexual beliefs and behaviors as risky, which in turn encouraged men to commit to and enact change. New HIV prevention interventions should include activities in their curriculum that foster critical self-reflection on assumptions.

Factors confounding the assessment of reflection: a critical review

PubMed Central

2011-01-01

Background Reflection on experience is an increasingly critical part of professional development and lifelong learning. There is, however, continuing uncertainty about how best to put principle into practice, particularly as regards assessment. This article explores those uncertainties in order to find practical ways of assessing reflection. Discussion We critically review four problems: 1. Inconsistent definitions of reflection; 2. Lack of standards to determine (in)adequate reflection; 3. Factors that complicate assessment; 4. Internal and external contextual factors affecting the assessment of reflection. Summary To address the problem of inconsistency, we identified processes that were common to a number of widely quoted theories and synthesised a model, which yielded six indicators that could be used in assessment instruments. We arrived at the conclusion that, until further progress has been made in defining standards, assessment must depend on developing and communicating local consensus between stakeholders (students, practitioners, teachers, supervisors, curriculum developers) about what is expected in exercises and formal tests. Major factors that complicate assessment are the subjective nature of reflection's content and the dependency on descriptions by persons being assessed about their reflection process, without any objective means of verification. To counter these validity threats, we suggest that assessment should focus on generic process skills rather than the subjective content of reflection and where possible to consider objective information about the triggering situation to verify described reflections. Finally, internal and external contextual factors such as motivation, instruction, character of assessment (formative or summative) and the ability of individual learning environments to stimulate reflection should be considered.

A critical care network pressure ulcer prevention quality improvement project.

PubMed

McBride, Joanna; Richardson, Annette

2015-03-30

Pressure ulcer prevention is an important safety issue, often underrated and an extremely painful event harming patients. Critically ill patients are one of the highest risk groups in hospital. The impact of pressure ulcers are wide ranging, and they can result in increased critical care and the hospital length of stay, significant interference with functional recovery and rehabilitation and increase cost. This quality improvement project had four aims: (1) to establish a critical care network pressure ulcer prevention group; (2) to establish baseline pressure ulcer prevention practices; (3) to measure, compare and monitor pressure ulcers prevalence; (4) to develop network pressure ulcer prevention standards. The approach used to improve quality included strong critical care nursing leadership to develop a cross-organisational pressure ulcer prevention group and a benchmarking exercise of current practices across a well-established critical care Network in the North of England. The National Safety Thermometer tool was used to measure pressure ulcer prevalence in 23 critical care units, and best available evidence, local consensus and another Critical Care Networks' bundle of interventions were used to develop a local pressure ulcer prevention standards document. The aims of the quality improvement project were achieved. This project was driven by successful leadership and had an agreed common goal. The National Safety Thermometer tool was an innovative approach to measure and compare pressure ulcer prevalence rates at a regional level. A limitation was the exclusion of moisture lesions. The project showed excellent engagement and collaborate working in the quest to prevent pressure ulcers from many critical care nurses with the North of England Critical Care Network. A concise set of Network standards was developed for use in conjunction with local guidelines to enhance pressure ulcer prevention. © 2015 British Association of Critical Care Nurses.

Tutticci, Naomi; Lewis, Peter A; Coyer, Fiona

2016-05-01

Critical reflection underpins critical thinking, a highly desirable generic nursing graduate capability. To improve the likelihood of critical thinking transferring to clinical practice, reflective thinking needs to be measured within the learning space of simulation. This study was divided into two phases to address the reliability and validity measures of previously untested surveys. Phase One data was collected from individuals (n = 6) using a 'think aloud' approach and an expert panel to review content validity, and verbatim comment analysis was undertaken. The Reflective Thinking Instrument and Critical Reflection Self-Efficacy Visual Analogue Scale items were contextualised to simulation. The expert review confirmed these instruments exhibited content validity. Phase Two data was collected through an online survey (n = 58). Cronbach's alpha measured internal consistency and was demonstrated by all subscales and the Instrument as a whole (.849). There was a small to medium positive correlation between critical reflection self-efficacy and general self-efficacy (r = .324, n = 56, p = .048). Participant responses were positive regarding the simulation experience. The research findings demonstrated that the Reflective Thinking and Simulation Satisfaction survey is reliable. Further development of this survey to establish validity is recommended to make it viable. Copyright © 2016 Elsevier Ltd. All rights reserved.

Reflective blogs in clinical education to promote critical thinking in dental hygiene students.

Wetmore, Ann O'Kelley; Boyd, Linda D; Bowen, Denise M; Pattillo, Robin E

2010-12-01

One challenge facing dental hygiene, as well as dental, education is to identify clinical teaching strategies promoting critical thinking and clinical reasoning. These skills are crucial elements in the practice of dental hygiene. A two-group design (intervention, n=28, and control, n=30) assessed first-year dental hygiene students using pre-and post-Health Science Reasoning Test (HSRT) scores to evaluate the effect of reflective blogging on critical thinking skills. A reflective blog rubric, based on Mezirow's levels of reflection, determined if reflective blogging increased the level of reflection for dental hygiene students. The results suggest within this nonprobability sample that reflective blogging did not produce a significant change in students' HSRT scores (p>0.05). However, analyses of reflective blog rubric scores demonstrated statistically significant improvements (p<0.05) in students' levels of reflection. Furthermore, data analysis revealed a correlation (p<0.05) between HSRT subscale scores and the element of reflection scores for the intervention group. This study addressed needs of the dental and dental hygiene education community by examining the use of blogs, an emerging technology, as a tool for reflecting on clinical experiences and, in turn, for promoting critical thinking.

Critical reflection and teacher capacity: The secondary science pre-service teacher population

NASA Astrophysics Data System (ADS)

Krim, Jessica Sarah

This qualitative study seeks to understand the development of secondary science pre-service teachers. A case study is developed about each of the five participants, in effort to answer the research questions, which are: How did critical reflection inform teacher capacity within the secondary science pre-service teacher population? What knowledge, skills, and dispositions facilitated secondary science pre-service teachers in developing a critically reflective practice? It is the author's expectation that by teaching these pre-service educators to develop their skills of critical reflection by using external methods of assessment such as videotaping, peer feedback, and student work, the participants in this study will increase and expand their capacity as teachers, or their "innate potential for growth, development, and accomplishment" (McDiarmid & Clevenger-Bright, 2008), and be better prepared to accomplish the goals that are expected of a master teacher. Data is collected from interviews, participant work samples, and observations from the researcher and other key individuals who worked with each participant, such as: the methods instructor, university supervisors, and cooperating teachers. Over the course of two semesters, the researcher developed a detailed description of each of the participants through analyzing passages selected from interview transcripts and student work samples for reflection type, factor of teacher capacity, and commonplace interaction group. The first outcome of this study includes an understanding of the relationship between critical reflection and teacher capacity and the knowledge, skills and dispositions that facilitate the development of a critically reflective practice. The second outcome of this study was the development of a new adaptation of a teacher interaction model (commonplace interaction groups) based on Schwab's Commonplaces of Educating. Lastly, three conclusions were drawn about the five participants in this study: There

Self-assessment, reflection on practice and critical thinking in nursing students.

PubMed

Siles-González, José; Solano-Ruiz, Carmen

2016-10-01

In accordance with the principles of the European Higher Education Area, the aim of this study was to contribute to the implementation of self-assessment through the application of reflection on learning and critical thinking. The theoretical framework employed was Habermas's critical theory and emancipatory interest as a preliminary step to generate educational transformations. The methodological contribution is the design a student self-assessment document that promotes reflection on action and critical thinking. The development of assessment through peer evaluation and other intermediate solutions until achieving self-assessment entails a shift in the educational and scientific paradigm, but also involves the implementation in practice of democratic and ethical principles, values and premises in society. Self-assessment is a novel concept for students, and obliges them to reinterpret their role. Due to the diversity of students' principles, values, motivations, interests and aspirations, this reinterpretation of their role can have a positive outcome, stimulating an active and critical attitude towards group work and self-assessment; or, on the contrary, can generate a stance characterised by disinterest, passivity and lack of critical thinking. The forms of assessment adopted in a given educational system reflect ways of thinking related to ideologies, values, ethical principles and educational paradigms: in order to render implementation of effective self-assessment feasible, it is necessary to undertake structural and regulatory reforms. Students have little experience of reflection on practice or critical thinking. Massification and cultural and structural factors determine the form of assessment. In this context, it would seem advisable to move towards self-assessment gradually and cautiously. Copyright © 2016 Elsevier Ltd. All rights reserved.

Keeping the Spirit of Community Partnerships Alive in the Scale Up of HIV/AIDS Prevention: Critical Reflections on the Roll Out of DEBI (Diffusion of Effective Behavioral Interventions)

PubMed Central

Pinto, Rogério M.; Hunter, Joyce; Rapkin, Bruce; Remien, Robert H.

2009-01-01

DEBI, or the Diffusion of Effective Behavioral Interventions is the largest centralized effort to diffuse evidence-based prevention science to fight HIV/AIDS in the United States. DEBI seeks to ensure that the most effective science-based prevention interventions are widely implemented across the country in community-based organizations. Thus, this is a particularly timely juncture in which to critically reflect on the extent to which known principles of community collaboration have guided key processes associated with the DEBI rollout. We review the available evidence on how the dissemination of packaged interventions is necessary but not sufficient for ensuring the success of technology transfer. We consider additional principles that are vital for successful technology transfer, which were not central considerations in the rollout of the DEBI initiative. These issues are: (1) community perceptions of a top-down mode of dissemination; (2) the extent to which local innovations are being embraced, bolstered, or eliminated; and (3) contextual and methodological considerations that shape community preparedness. Consideration of these additional factors is necessary in order to effectively document, manage, and advance the science of dissemination and technology transfer in centralized prevention efforts within and outside of HIV/AIDS.

Walker, Rachel; Cooke, Marie; Henderson, Amanda; Creedy, Debra K

2013-05-01

Learning circles are an enabling process to critically examine and reflect on practices with the purpose of promoting individual and organizational growth and change. The authors adapted and developed a learning circle strategy to facilitate open discourse between registered nurses, clinical leaders, clinical facilitators and students, to critically reflect on practice experiences to promote a positive learning environment. This paper reports on an analysis of field notes taken during a critical reflection process used to create an effective learning community in the workplace. A total of 19 learning circles were conducted during in-service periods (that is, the time allocated for professional education between morning and afternoon shifts) over a 3 month period with 56 nurses, 33 students and 1 university-employed clinical supervisor. Participation rates ranged from 3 to 12 individuals per discussion. Ten themes emerged from content analysis of the clinical learning issues identified through the four-step model of critical reflection used in learning circle discussions. The four-step model of critical reflection allowed participants to reflect on clinical learning issues, and raise them in a safe environment that enabled topics to be challenged and explored in a shared and cooperative manner.

1972-01-01

Clean criticality data were obtained from molybdenum-reflected cylindrical uranyl-fluoride-water solution reactors. Using ENDF/B molybdenum cross sections, a nine energy group two-dimensional transport calculation of a reflected reactor configuration predicted criticality to within 7 cents of the experimental value. For these reactors, it was necessary to compute the reflector resonance integral by a detailed transport calculation at the core-reflector interface volume in the energy region of the two dominant resonances of natural molybdenum.

Reflection: a critical proficiency essential to the effective development of a high competence in communication.

PubMed

Adams, Cindy L; Nestel, Debra; Wolf, Peter

2006-01-01

Reflection, or the ability to step back from an experience and consider it critically, in an analytical, non-subjective manner, is an essential aspect of problem solving and decision making, and also of effective communication with clients and colleagues. Reflective practice has been described as the essence of professionalism and is therefore a core professional skill; rarely, however, has it been explicitly taught in veterinary curricula, and it has only a recent history in undergraduate human medical curricula. We describe here two preliminary case studies, one in a veterinary medical education context and the other within a human medical education framework, as examples of approaches to assessing a student's ability for ''reflection.'' The case studies also illustrate some of the key principles. Both of the case studies described had as their end goal the enhancement of communication skills through critical reflection. At Monash University, Australia, the majority of students were assessed as being at a level of ''reflection in development.'' The students in the Ontario Veterinary College case study showed moderately good use of self-awareness and critical reflection as a basis for modifying and integrating communication skills into practice. While both preliminary case studies point to the fact that students recognize the importance of communication and value the opportunity to practice it, few students in either case study identified the importance of reflection for lifelong learning and professional competence. Opportunities to complete critical reflection exercises in other parts of curricula and outside of communication would likely reinforce its importance as a generic skill. Ongoing scholarly approaches to teaching, learning, and evaluating reflection and self-awareness are needed.

Critical components of reflective supervision: responses from expert supervisors in the field.

Tomlin, Angela M; Weatherston, Deborah J; Pavkov, Thomas

2014-01-01

This article offers a brief review of the history of supervision, defines reflective supervision, and reports the results of a Delphi study designed to identify critical components of reflective supervision. Academicians and master clinicians skilled in providing reflective supervision participated in a three-phase survey to elicit beliefs about best practice when engaging in reflective supervision. The process yielded consensus descriptions of optimal characteristics and behaviors of supervisors and supervisees when entering into supervisory relationships that encourage reflective practice. These results, although preliminary, suggest that it is possible to identify elements that are integral to effective reflective supervision. These initial findings may be used for future study of the reflective supervisory process. © 2013 Michigan Association for Infant Mental Health.

Better understanding of critically reflective work behavior (CRWB), an approach for work-related informal learning, is important in order to gain more profound insight in the continuing development of health care professionals. A survey, developed to measure CRWB and its predictors, was distributed to veterinary professionals. The authors specified a model relating CRWB to a Perceived Need for Lifelong Learning, Perceived Workload, and Opportunities for Feedback. Furthermore, research utilization was added to the concept of CRWB. The model was tested against the data, using structural equation modeling (SEM). The model was well represented by the data. Four factors that reflect aspects of CRWB were distinguished: (1) individual CRWB; (2) being critical in interactions with others; (3) cross-checking of information; and (4) openness to new findings. The latter 2 originated from the factor research utilization in CRWB. The Perceived Need for Lifelong Learning predicts CRWB. Neither Perceived Workload nor Opportunities for Feedback of other practitioners was related to CRWB. The results suggest that research utilization, such as cross-checking information and openness to new findings, is essential for CRWB. Furthermore, perceptions of the need for lifelong learning are more relevant for CRWB of health care professionals than qualities of the workplace.

To facilitate interdisciplinary collaboration and to make connections between patients' diseases and their social/cultural contexts, the study examined whether the use of heterogeneous cluster grouping in reflective writing for medical humanities literature acquisition could have positive effects on medical university students in terms of empathy, critical thinking, and reflective writing. A 15-week quasi-experimental design was conducted to investigate the learning outcomes. After conducting cluster algorithms, heterogeneous learning clusters (experimental group; n = 43) and non-heterogeneous learning clusters (control group; n = 43) were derived for a medical humanities literature study. Before and after the intervention, an Empathy Scale in Patient Care (ES-PC), a critical thinking disposition assessment (CTDA-R), and a reflective writing test were administered to both groups. The findings showed that on the empathy scale, significant differences in the "behavioral empathy," "affective empathy," and overall sections existed between the post-test mean scores of the experimental group and those of the control group, but such differences did not exist in "intelligent empathy." Regarding critical thinking, there were significant differences in "systematicity and analyticity," "skepticism and well-informed," "maturity and skepticism," and overall sections. As for reflective writing, significant differences existed in "ideas," "voice and point of view," "critical thinking and representation," "depth of reflection on personal growth," and overall sections, but not in "focus and context structure" and "language and conventions." This study outlined an alternative for using heterogeneous cluster grouping in reflective writing about medical humanities literature to facilitate interdisciplinary cooperation to provide more humanizing medical care.

Effectiveness of past and current critical incident analysis on reflective learning and practice change.

PubMed

Vachon, Brigitte; LeBlanc, Jeannette

2011-09-01

Critical incident analysis (CIA) is one of the strategies frequently used to facilitate reflective learning. It involves the thorough description and analysis of an authentic and experienced event within its specific context. However, CIA has also been described as having the potential to expose vulnerabilities, threaten learners' coping mechanisms and increase rather than reduce their anxiety levels. The aim of this study was to compare the analysis of current critical incidents with that of past critical incidents, and to further explore why and how the former is more conducive to reflective learning and practice change than the latter. A collaborative research study was conducted. Eight occupational therapists were recruited to participate in a reflective learning group that convened for 12 meetings held over a 15-month period. The group facilitator planned and adapted the learning strategies to be used to promote reflective learning and guided the group process. Critical incident analysis represented the main activity carried out in the group discussions. The data collected were analysed using the grounded theory method. Three phenomena were found to differentiate between the learning contexts created by the analysis of, respectively, past and current critical incidents: attitudinal disposition; legitimacy of purpose, and the availability of opportunities for experimentation. Analysis of current clinical events was found to improve participants' motivation to self-evaluate, to increase their self-efficacy, and to help them transfer learning into action and to progressively self-regulate. The results of this collaborative research study suggest that the analysis of current clinical events in order to promote reflection offers a safer and more constructive learning environment than does the analysis of incidents that have occurred in the past. This learning strategy is directly grounded in health professional practice. The remaining challenge for continuing

The education of health practitioners supporting breastfeeding women: time for critical reflection.

PubMed

Dykes, Fiona

2006-10-01

The protection, promotion and support of breastfeeding has now become a major international priority as emphasized in the Global Strategy for Infant and Young Child Feeding. Health practitioners, such as midwives, nurses and doctors, have a key role to play in providing support to breastfeeding women. This paper provides a critical discussion of educational requirements of health practitioners to equip them for their supportive role. The effective integration of embodied, vicarious, practice-based and theoretical knowledge requires opportunities for deep critical reflection. This approach should facilitate personal reflection and critical engagement with broader socio-political issues, thus allowing for collective understandings and change. Practitioners also need to understand breastfeeding as a biopsychosocial process that is dynamic, relational and changes over time. Recommendations are outlined with regards to multidisciplinary undergraduate education; mentorship schemes with knowledgeable role models supporting student practitioners; involvement of voluntary and peer supporters; post-registration education; setting of national standards for breastfeeding education; tailored education for specific groups; designated funding; and involvement of breastfeeding specialists.

JOHNSON, Susan L.

2016-01-01

Aim To analyze the discourses of workplace bullying prevention of hospital nursing unit managers and in the official documents of the organizations where they worked. Background Workplace bullying can be a self-perpetuating problem in nursing units. As such, efforts to prevent this behavior may be more effective than efforts to stop the behavior. There is limited research on how healthcare organizations characterize their efforts to prevent workplace bullying. Design This was a qualitative study. Method Critical discourse analysis and Foucault’s writings on governmentality and discipline were used to analyze data from interviews with hospital nursing unit managers (n=15) and organizational documents (n=22). Data were collected in 2012. Findings The discourse of workplace bullying prevention centered around three themes: prevention of workplace bullying through managerial presence, normalizing behaviors and controlling behaviors. All three are individual level discourses of workplace bullying prevention. Conclusion Current research indicates that workplace bullying is a complex issue with antecedents at the individual, departmental and organizational level. However, the discourse of the participants in this study only focused on prevention of bullying by moulding the behaviors of individuals. The effective prevention of workplace bullying will require departmental and organizational initiatives. Leaders in all types of organizations can use the results of this study to examine their organizations’ discourses of workplace bullying prevention to determine where change is needed. PMID:26010268

Naber, Jessica L; Hall, Joanne; Schadler, Craig Matthew

2014-09-01

This study sought to identify characteristics of clinically situated critical thinking in nursing students' reflections, originally part of a study guided by Richard Paul's model of critical thinking. Nurses are expected to apply critical thinking in all practice situations to improve health outcomes, including patient safety and satisfaction. In a previous study, Paul's model of critical thinking was used to develop questions for reflective writing assignments. Within that study, 30 nursing students completed six open-ended narratives of nurse-patient clinical encounters during an 8-week period. Improvements were seen in critical thinking scores after the intervention. This article reports the qualitative analysis of the content of six open-ended narratives. Six overarching themes were identified and combined into a tentative conceptual model. Faculty's understanding of the characteristics of critical thinking in the context of clinical education will help them to teach and evaluate students' progress and competencies for future practice.

Moving from technical to critical reflection in journalling: an investigation of students' ability to incorporate three levels of reflective writing.

PubMed

Usher, K; Tollefson, J; Francis, D

2001-01-01

This paper outlines a research project aimed at changing the levels of reflection of preregistration nursing students in a tertiary institution. Whilst reflection is widely espoused now in nursing, few studies have been found that identify whether the level of reflective writing can be identified or developed by students. Anecdotal and research evidence (Powell 1989; van Manen 1977) however indicates that most student reflective writing occurs at the technical level. A descriptive exploratory study using both qualitative and quantitative techniques was undertaken to apply van Manen's (1977) levels in a structured way in an attempt to facilitate the student's understanding and use of the levels in their reflective writing. The findings of the study indicate that student self evaluation and identification of the levels in their own writing can lead to change in the levels of critical reflective writing achieved by undergraduate students.

Zhu, Li; Martins, Vanderlei J.; Remer, Lorraine A.

2010-01-01

This research uses the critical reflectance technique, a space-based remote sensing method, to measure the spatial distribution of aerosol absorption properties over land. Choosing two regions dominated by biomass burning aerosols, a series of sensitivity studies were undertaken to analyze the potential limitations of this method for the type of aerosol to be encountered in the selected study areas, and to show that the retrieved results are relatively insensitive to uncertainties in the assumptions used in the retrieval of smoke aerosol. The critical reflectance technique is then applied to Moderate Resolution Imaging Spectrometer (MODIS) data to retrieve the spectral aerosol single scattering albedo (SSA) in South African and South American 35 biomass burning events. The retrieved results were validated with collocated Aerosol Robotic Network (AERONET) retrievals. One standard deviation of mean MODIS retrievals match AERONET products to within 0.03, the magnitude of the AERONET uncertainty. The overlap of the two retrievals increases to 88%, allowing for measurement variance in the MODIS retrievals as well. The ensemble average of MODIS-derived SSA for the Amazon forest station is 0.92 at 670 nm, and 0.84-0.89 for the southern African savanna stations. The critical reflectance technique allows evaluation of the spatial variability of SSA, and shows that SSA in South America exhibits higher spatial variation than in South Africa. The accuracy of the retrieved aerosol SSA from MODIS data indicates that this product can help to better understand 44 how aerosols affect the regional and global climate.

Reflection a neglected art in health promotion.

PubMed

Fleming, Paul

2007-10-01

Evaluation and quality assurance have, over time, become the bedrock of health promotion practice in ensuring effectiveness and efficiency of programme planning and delivery. There has been less emphasis, however, on formal recognition of the contribution of the personal characteristics and perspectives of those who plan and deliver programmes and to the more subtle underlying effects of prevailing societal and professional norms. This paper seeks to highlight the neglect of formal reflection as a key professional skill in professional health promotion practice. It outlines key theories underpinning the development of the concepts of reflection and reflective practice. The role of reflection in critical health education as it contributes to critical consciousness raising is highlighted through its contribution to the empowerment of change agents in a societal change context. A conceptual typology of reflective practice is described which provides a flexible structure with which professionals can reflect on the role of self, the context and the process of health promotion programme planning. Its use is illustrated from the author's published work in health promotion which is related to prevention of workplace violence.

Padden-Denmead, Mary L; Scaffidi, Rose M; Kerley, Regina M; Farside, Amy Lee

2016-11-01

Simulation and guided reflective journaling have been identified as effective teaching and learning methods to develop critical thinking (CT) and clinical reasoning skills in nursing students. A descriptive correlational design was used to determine the relationship between CT and level of reflection using the Holistic Critical Thinking Skills Rubric (HCTSR) and the level of reflection on action assessment (LORAA), respectively, to evaluate 23 baccalaureate student-guided reflective journal entries after a simulation exercise with guided debriefing and after two subsequent clinical experiences. A statistically significant positive relationship (p < .01) was found between mean HCTSR and LORAA scores on all three journal entries, but no relationship to CT during simulation or on standardized test scores. The results also indicated support for use of the guided reflection after significant learning experiences. The LORAA and the HCTSR are effective measures of level of reflection and CT to evaluate learning from simulation and clinical experiences. [J Nurs Educ. 2016;55(11):645-650.].

2017-09-01

The aim of this study was to evaluate the effects of reflective trainings for nursing students on their critical thinking disposition. A total of 157 senior undergraduate nursing students sampled from Hainan Medical University in China participated in this study in 2014. They were randomly divided into experimental and control groups. The experimental group students were provided the reflective training during their entire 12-month clinical internship, whereas students in the control group were requested to keep their reflective diaries but without a formal training. Before and after the intervention, nursing students' critical thinking disposition was rated using the Chinese version of Critical Thinking Disposition Inventory (CTDI-CV). Before the start of the intervention, the critical thinking disposition scores of the two groups had no significant differences. At the end of the intervention, it was found that the experimental students performed better in each subscale of CTDI-CV. These include the search for truth, open mind, analytical ability, systematic ability, critical thinking, self-confidence, curiosity, and cognitive maturity. By summing the scores of all categories, the results showed that the experimental group had a significantly higher total score than that of the control group (p ≤ .044). Evaluating the score difference in each function indicated that there was a range of improvements on the critical thinking disposition because of the reflective training intervention. Reflective training during the internship period improves nursing students' disposition of critical thinking and promotes their readiness for their clinical practices in the rapidly increasing demands of the healthcare field.

2014-01-01

The importance of critical thinking is well-documented by the American Association of Colleges of Nursing and the National League for Nursing. Reflective writing is often used to increase understanding and analytical ability. The lack of empirical evidence about the effect of reflective writing interventions on critical thinking supports the examination of this concept. Study objectives were: This study used an experimental, pretest-posttest design. The setting was two schools of nursing at universities in the southern United States. The convenience sample included 70 fourth-semester students in baccalaureate nursing programs. Randomly assigned control and experimental groups completed the California Critical Thinking Skills Test (CCTST) and the California Critical Thinking Dispositions Inventory Test (CCTDI). The experimental group completed six reflective writing assignments. Both groups completed the two tests again. Results showed that the experimental group had a significant increase (p=0.03) on the truthseeking subscale of the CCTDI when compared to the control group. The experimental group's scores increased on four CCTST subscales and were higher than the control group's on three CCTST subscales. The results of this study make it imperative for nursing schools to consider including reflective writing-especially assignments based on Paul's (1993) model-in nursing courses. If future studies, testing over longer periods of time, show significant increases in critical thinking, those interventions could be incorporated into nursing curriculum and change the way nurse educators evaluate students.

The extent to which the public health 'war on obesity' reflects the ethical values and principles of critical health promotion: a multimedia critical discourse analysis.

PubMed

O'Hara, Lily; Taylor, Jane; Barnes, Margaret

2015-12-01

The discipline of health promotion is responsible for implementing strategies within weight-related public health initiatives (WR-PHI). It is imperative that such initiatives be subjected to critical analysis through a health promotion ethics lens to help ensure ethical health promotion practice. Multimedia critical discourse analysis was used to examine the claims, values, assumptions, power relationships and ideologies within Australian WR-PHI. The Health Promotion Values and Principles Continuum was used as a heuristic to evaluate the extent to which the WR-PHI reflected the ethical values of critical health promotion: active participation of people in the initiative; respect for personal autonomy; beneficence; non-maleficence; and strong evidential and theoretical basis for practice. Ten initiatives were analysed. There was some discourse about the need for participation of people in the WR-PHI, but people were routinely labelled as 'target groups' requiring 'intervention'. Strong evidence of a coercive and paternalistic discourse about choice was identified, with minimal attention to respect for personal autonomy. There was significant emphasis on the beneficiaries of the WR-PHI but minimal attention to the health benefits, and nothing about the potential for harm. Discourse about the evidence of need was objectivist, and there was no discussion about the theoretical foundations of the WR-PHI. The WR-PHI were not reflective of the ethical values and principles of critical health promotion. So what? Health promotion researchers and practitioners engaged in WR-PHI should critically reflect on the extent to which they are consistent with the ethical aspects of critical health promotion practice.

Thermoacoustic effects in supercritical fluids near the critical point: Resonance, piston effect, and acoustic emission and reflection

NASA Astrophysics Data System (ADS)

Onuki, Akira

2007-12-01

We present a general theory of thermoacoustic phenomena in one phase states of one-component fluids. Singular behavior is predicted in supercritical fluids near the critical point. In a one-dimensional geometry we start with linearized hydrodynamic equations taking into account the effects of heat conduction in the boundary walls and the bulk viscosity. We introduce a coefficient Z(ω) characterizing reflection of sound with frequency ω at the boundary in a rigid cell. As applications, we examine acoustic eigenmodes, response to time-dependent perturbations, and sound emission and reflection. Resonance and rapid adiabatic changes are noteworthy. In these processes, the role of the thermal diffusion layers is enhanced near the critical point because of the strong critical divergence of the thermal expansion.

Researching "race" in lesbian space: a critical reflection.

PubMed

Held, Nina

2009-01-01

Feminist researchers have acknowledged that racial differences between researcher and researched impact on the research process; however, there has been little concern with how "race" is actually made in/through the research process. If we think "race" as performative and as always in the process of being made then this theoretical claim has crucial implications for research encounters. In this article the author draws on her own research, which focuses on processes of racialization. This ethnographic study was conducted in two lesbian bars in the North West of England. The article illustrates different ways of how "race," in particular Whiteness, operated during the research process. The author critically reflects on her role in "race making" during this process and highlights the importance of acknowledging that researchers are also complicit in this making when doing research where "race" is not the central focus.

A zero-power critical assembly was designed, constructed, and operated for the purpose of conducting a series of benchmark experiments dealing with the physics characteristics of a UN-fueled, Li-7 cooled, Mo-reflected, drum-controlled compact fast reactor for use with a space-power electric conversion system. The experimental program consisted basically of measuring the differential neutron spectra and the changes in critical mass that accompanied the stepwise addition of (Li-7)3N, Hf, Ta, and W to a basic core fueled with U metal in a pin-type Ta honeycomb structure. In addition, experimental results were obtained on power distributions, control characteristics, neutron lifetime, and reactivity worths of numerous absorber, structural, and scattering materials.

Spectroscopic refractometer for transparent and absorbing liquids by reflection of white light near the critical angle

DOE Office of Scientific and Technical Information (OSTI.GOV)

Sanchez-Perez, C.; Garcia-Valenzuela, A.

2012-11-15

We propose and evaluate a spectroscopic refractometer device to measure the refractive index dispersion of transparent and absorbing solutions. The angle-dependent reflectivity of a white beam of light in an internal reflection configuration around the critical angle is spectrally analyzed. The refractive index in a wavelength range from 400 nm to 900 nm is obtained from the angle-reflectivity curve around the critical angle at each wavelength. The device does not use angle scanning mechanisms, decreasing considerably the complexity of the instrument in comparison to previous proposals. As a result, the measurements are obtained relatively fast. Nevertheless, a good experimental resolutionmore » in refractive index of about {Delta}n Almost-Equal-To 10{sup -4} at all the wavelengths is achieved in the case of transparent solutions. The calibration procedure of the device is discussed in detail. We also present measurements of the refractive index dispersion of rhodamine 6G-methanol solutions, which has a strong absorption band in the visible spectra.« less

A reflective lens: applying critical systems thinking and visual methods to ecohealth research.

PubMed

Cleland, Deborah; Wyborn, Carina

2010-12-01

Critical systems methodology has been advocated as an effective and ethical way to engage with the uncertainty and conflicting values common to ecohealth problems. We use two contrasting case studies, coral reef management in the Philippines and national park management in Australia, to illustrate the value of critical systems approaches in exploring how people respond to environmental threats to their physical and spiritual well-being. In both cases, we used visual methods--participatory modeling and rich picturing, respectively. The critical systems methodology, with its emphasis on reflection, guided an appraisal of the research process. A discussion of these two case studies suggests that visual methods can be usefully applied within a critical systems framework to offer new insights into ecohealth issues across a diverse range of socio-political contexts. With this article, we hope to open up a conversation with other practitioners to expand the use of visual methods in integrated research.

Empowering adolescent girls in Sub-Saharan Africa to prevent unintended pregnancy and HIV: A critical research gap.

PubMed

Phillips, Sharon J; Mbizvo, Michael T

2016-01-01

The need to prevent early pregnancy and HIV among adolescent girls in Sub-Saharan Africa has been recognized increasingly over recent years. Although extensive work has been done to determine appropriate interventions for girls in high-income countries, very little evidence is available to guide programmatic interventions in Sub-Saharan Africa. The available evidence has been equivocal regarding improved outcomes. While knowledge and self-reported behaviors frequently change with interventions, including those performed at the community level, educational programs, and direct contraceptive provision, downstream outcomes rarely reflect a significant effect of the interventions; however, provision of financial or other interventions to incentivize continued school enrollment are a promising development. We suggest directions for future research to fill this critical gap in the literature. Copyright © 2015 International Federation of Gynecology and Obstetrics. Published by Elsevier Ireland Ltd.

A Critical Assessment of Vector Control for Dengue Prevention

Achee, Nicole L.; Gould, Fred; Perkins, T. Alex; Reiner, Robert C.; Morrison, Amy C.; Ritchie, Scott A.; Gubler, Duane J.; Teyssou, Remy; Scott, Thomas W.

2015-01-01

Recently, the Vaccines to Vaccinate (v2V) initiative was reconfigured into the Partnership for Dengue Control (PDC), a multi-sponsored and independent initiative. This redirection is consistent with the growing consensus among the dengue-prevention community that no single intervention will be sufficient to control dengue disease. The PDC's expectation is that when an effective dengue virus (DENV) vaccine is commercially available, the public health community will continue to rely on vector control because the two strategies complement and enhance one another. Although the concept of integrated intervention for dengue prevention is gaining increasingly broader acceptance, to date, no consensus has been reached regarding the details of how and what combination of approaches can be most effectively implemented to manage disease. To fill that gap, the PDC proposed a three step process: (1) a critical assessment of current vector control tools and those under development, (2) outlining a research agenda for determining, in a definitive way, what existing tools work best, and (3) determining how to combine the best vector control options, which have systematically been defined in this process, with DENV vaccines. To address the first step, the PDC convened a meeting of international experts during November 2013 in Washington, DC, to critically assess existing vector control interventions and tools under development. This report summarizes those deliberations. PMID:25951103

Fisher, Kimberly A; Ahmad, Sumera; Jackson, Madeline; Mazor, Kathleen M

2016-10-01

To describe surrogate decision makers' (SDMs) perspectives on preventable breakdowns in care among critically ill patients. We screened 70 SDMs of critically ill patients for those who identified a preventable breakdown in care, defined as an event where the SDM believes something "went wrong", that could have been prevented, and resulted in harm. In-depth interviews were conducted with SDMs who identified an eligible event. 32 of 70 participants (46%) identified at least one preventable breakdown in care, with a total of 75 discrete events. Types of breakdowns involved medical care (n=52), communication (n=59), and both (n=40). Four additional breakdowns were related to problems with SDM bedside access to the patient. Adverse consequences of breakdowns included physical harm, need for additional medical care, emotional distress, pain, suffering, loss of trust, life disruption, impaired decision making, and financial expense. 28 of 32 SDMs raised their concerns with clinicians, yet only 25% were satisfactorily addressed. SDMs of critically ill patients frequently identify preventable breakdowns in care which result in harm. An in-depth understanding of the types of events SDMs find problematic and the associated harms is an important step towards improving the safety and patient-centeredness of healthcare.

The Challenges of Participant Photography: A Critical Reflection on Methodology and Ethics in Two Cultural Contexts.

PubMed

Murray, Linda; Nash, Meredith

2017-05-01

Photovoice and photo-elicitation are two common methods of participant photography used in health research. Although participatory photography has many benefits, this critical reflection provides fellow researchers with insights into the methodological and ethical challenges faced when using such methods. In this article, we critically reflect on two studies that used participatory photography in different cultural contexts. The first study used photo-elicitation to investigate mothers' experiences of infant settling in central Vietnam. The second study used photovoice to explore pregnant embodiment in Australia. Following a discussion of the literature and a detailed overview of the two studies, we examine the methodological challenges in using participant photography before, during and after each study. This is followed by a discussion of ethical concerns that arose in relation to the burden of participation, confidentiality, consent, and the photographing of families and children. To conclude, we highlight implications for using participatory photography in other settings.

[Prevention and management of refeeding syndrome in patients with chronic critical illness].

PubMed

Chen, Jun; Fan, Chaogang

2016-07-01

Nutritional support is an important means to treat the patients with chronic critical illness for commonly associated malnutrition. Refeeding syndrome is a serious complication during the process, mainly manifested as severe electrolyte with hypophosphataemia being the most common. Refeeding syndrome is not uncommon but it is often ignored. In our future clinical work, we need to recognize this chinical situation and use preventative and treatment measures. According to NICE clinical nutrition guideline, we discussed the risk factors, treatment methods and preventive measures of refeeding syndrome in patients with chronic critical illness. We argued that for patients with high risk refeeding syndrome, nutritional support treatment should be initially low calorie and slowly increased to complete requirement. Circulation capacity should be recovered, fluid balance must be closely monitored and supplement of vitamins, microelement, electrolytes should be noted. After the emergence of refeeding syndrome, we should reduce or even stop the calorie intake, give an active treatment for electrolyte disorder, provide vitamin B, and maintain the functions of multiple organs.

Kuchan, Karen L

2009-01-01

An epistemological web invites critical reflection and the possibility of new ideas emerging in the space between experience and different ways of thinking. A web offers a postmodern method of a hermeneutic of experience and a way of knowing that creates space for a robust, flexible, dynamic process of critical reflection and discovery. The following article utilizes an inter-textual epistemological web (see Figure 1, p. 4) to answer the question, "Do metaphors of experience and experiences of metaphor during contemplative healing prayer with a spiritual director nurture a transformational process toward aliveness and compassion?" How can one discover and communicate this reality in dialog with Hebrew scripture, psychoanalytic theory, affective neuroscience and ways of thinking about contemplative transformation?

Scanning laser reflection tool for alignment and period measurement of critical-angle transmission gratings

NASA Astrophysics Data System (ADS)

Song, Jungki; Heilmann, Ralf K.; Bruccoleri, Alexander R.; Hertz, Edward; Schatternburg, Mark L.

2017-08-01

We report progress toward developing a scanning laser reflection (LR) tool for alignment and period measurement of critical-angle transmission (CAT) gratings. It operates on a similar measurement principle as a tool built in 1994 which characterized period variations of grating facets for the Chandra X-ray Observatory. A specularly reflected beam and a first-order diffracted beam were used to record local period variations, surface slope variations, and grating line orientation. In this work, a normal-incidence beam was added to measure slope variations (instead of the angled-incidence beam). Since normal incidence reflection is not coupled with surface height change, it enables measurement of slope variations more accurately and, along with the angled-incidence beam, helps to reconstruct the surface figure (or tilt) map. The measurement capability of in-grating period variations was demonstrated by measuring test reflection grating (RG) samples that show only intrinsic period variations of the interference lithography process. Experimental demonstration for angular alignment of CAT gratings is also presented along with a custom-designed grating alignment assembly (GAA) testbed. All three angles were aligned to satisfy requirements for the proposed Arcus mission. The final measurement of roll misalignment agrees with the roll measurements performed at the PANTER x-ray test facility.

2016-01-01

The central line (CL) bundle interventions are important for preventing central line-associated bloodstream infections (CLABSIs), but a modeling method for testing the CL bundle interventions within a health systems framework is lacking. Guided by the Quality Health Outcomes Model (QHOM), this study tested the CL bundle interventions in reflective and composite, latent, variable measurement models to assess the impact of the modeling approaches on an investigation of the relationships between adherence to the CL bundle interventions, organizational context, and CLABSIs. A secondary data analysis study was conducted using data from 614 U.S. hospitals that participated in the Prevention of Nosocomial Infection and Cost-Effectiveness Refined study. The sample was randomly split into exploration and validation subsets. The two CL bundle modeling approaches resulted in adequate fitting structural models (RMSEA = .04; CFI = .94) and supported similar relationships within the QHOM. Adherence to the CL bundle had a direct effect on organizational context (reflective = .23; composite = .20; p = .01) and CLABSIs (reflective = -.28; composite = -.25; p = .01). The relationship between context and CLABSIs was not significant. Both modeling methods resulted in partial support of the QHOM. There were little statistical, but large, conceptual differences between the reflective and composite modeling approaches. The empirical impact of the modeling approaches was inconclusive, for both models resulted in a good fit to the data. Lessons learned are presented. The comparison of modeling approaches is recommended when initially modeling variables that have never been modeled or with directional ambiguity to increase transparency and bring confidence to study findings.

The primary prevention of alcohol problems: a critical review of the research literature.

PubMed

Moskowitz, J M

1989-01-01

The research evaluating the effects of programs and policies in reducing the incidence of alcohol problems is critically reviewed. Four types of preventive interventions are examined including: (1) policies affecting the physical, economic and social availability of alcohol (e.g., minimum legal drinking age, price and advertising of alcohol), (2) formal social controls on alcohol-related behavior (e.g., drinking-driving laws), (3) primary prevention programs (e.g., school-based alcohol education), and (4) environmental safety measures (e.g., automobile airbags). The research generally supports the efficacy of three alcohol-specific policies: raising the minimum legal drinking age to 21, increasing alcohol taxes and increasing the enforcement of drinking-driving laws. Also, research suggests that various environmental safety measures reduce the incidence of alcohol-related trauma. In contrast, little evidence currently exists to support the efficacy of primary prevention programs. However, a systems perspective of prevention suggests that prevention programs may become more efficacious after widespread adoption of prevention policies that lead to shifts in social norms regarding use of beverage alcohol.

Murphy, Roger; Cox, Karen; Steward, William

2011-01-01

Objectives The experiences of patients diagnosed with advanced incurable cancer and the doctors who conducted their medical consultations were studied in order to improve the understanding of what happens in consultations, when bad news is disclosed. The major objective of the study was to critically reflect upon doctor-patient communication, in such situations, with a view to considering future strategies for doctors’ continuing professional development. Methods Sixteen patients and sixteen Oncologists, from a cancer centre in the UK were recruited into this ethnographic study. One hundred and fifteen episodes of data were collected from audio recorded consultations; interviews with doctors and patients and their relatives and observations of consultations. These data were analysed using a constant comparison method. Results Interactions between doctors and patients are complex and consultations can be challenging for both of them. Some doctors spoke openly about their need for additional support to enhance their communication related competencies within Oncology consultations. These doctors wanted to observe their peers conducting consultations. They also wanted to receive feedback about their own clinical practices. These doctors stated that they wanted an open culture whereby they could talk freely about difficult and emotionally challenging consultations without fear of being considered incompetent by their Consultants, who act in a clinical supervisory role. Conclusions To help practitioners consolidate their practice in such settings it is necessary to develop better collaborations among practitioners within clinical practice. Providing individual supervisory sessions or group workshops can facilitate reflective learning and provide an open and supportive learning culture.

Controlling and prevention of surface wrinkling via size-dependent critical wrinkling strain.

PubMed

Han, Xue; Zhao, Yan; Cao, Yanping; Lu, Conghua

2015-06-14

Surface wrinkling may occur in a film-substrate system when the applied strain exceeds the critical value. However, the practically required strain for the onset of surface wrinkling can be different from the theoretically predicted value. Here we investigate the film size effect-dependent critical strain for the mechanical strain-induced surface wrinkling via a combination of experiments and theoretical analysis. In the poly(dimethylsiloxane)-based system fabricated by the smart combination of mechanical straining and selective O2 plasma (OP) exposure through Cu grids, the film size effect on the critical wrinkling strain is systematically studied by considering OP exposure duration, the mesh number and geometry of Cu grids. Meanwhile, a simple analytical solution revealing the film size effect is well established, which shows good consistency with the experimental results. This study provides an experimental and theoretical basis for finely tuning the critical wrinkling strain in a simple and quantitative manner, which can find a wide range of applications in such fields as microelectronic circuits and optical devices, where controlling and/or prevention of surface wrinkling are of great importance.

Validation of Safety-Critical Systems for Aircraft Loss-of-Control Prevention and Recovery

NASA Technical Reports Server (NTRS)

Belcastro, Christine M.

2012-01-01

Validation of technologies developed for loss of control (LOC) prevention and recovery poses significant challenges. Aircraft LOC can result from a wide spectrum of hazards, often occurring in combination, which cannot be fully replicated during evaluation. Technologies developed for LOC prevention and recovery must therefore be effective under a wide variety of hazardous and uncertain conditions, and the validation framework must provide some measure of assurance that the new vehicle safety technologies do no harm (i.e., that they themselves do not introduce new safety risks). This paper summarizes a proposed validation framework for safety-critical systems, provides an overview of validation methods and tools developed by NASA to date within the Vehicle Systems Safety Project, and develops a preliminary set of test scenarios for the validation of technologies for LOC prevention and recovery

Critical thinking is a process applied to midwifery theory, research and experience. It is a positive activity, responsive to context, drawing on negative and positive triggers and emotions to suggest ways of acting in future. Practice-based and reflective midwifery assignments should reflect the midwifery goals of critical thinking. This may require adjustments in assessment criteria and a questioning of standard academic conventions.

The nursing practice is described as a scientific practice, but also as a practice where caring is important. The purpose of nursing education is to provide competent nursing practitioners. This implies that future practitioners must have both critical analytical thinking abilities, as well as empathy and moral values. Reflective thinking could probably accommodate these thinking skills. It seems that the facilitation of reflective thinking skills is essential in nursing education. The research question that is relevant in this context is: "What is reflective thinking?" The purpose of this article is to report on the concept analysis of reflective thinking and in particular on the connotative meaning (critical attributes) thereof. The method used to perform the concept analysis is based on the original method of Wilson (1987) as described by Walker & Avant (1995). As part of the concept analysis the connotations (critical attributes) are identified, reduced and organized into three categories, namely pre-requisites, processes and outcomes. A model case is described which confirms the essential critical attributes of reflective thinking. Finally a theoretical definition of reflective thinking is derived and reads as follows: Reflective thinking is a cyclic, hierarchical and interactive construction process. It is initiated, extended and continued because of personal cognitive-affective interaction (individual dimension) as well as interaction with the social environment (social dimension). to realize reflective thinking, a level of internalization on the cognitive and affective domain is required. The result of reflective thinking is a integrated framework of knowledge (meaningful learning) and a internalized value system providing a new perspective on and better understanding of a problem. Reflective thinking further leads to more effective decision making- and problem solving skills.

Practitioner insights on obesity prevention: the voice of South Australian OPAL workers.

PubMed

2016-06-01

Knowledge based on science has been central to implementing community-based childhood obesity prevention interventions. The art of practitioner wisdom is equally critical to ensure locally relevant responses. In South Australia (SA), the OPAL (Obesity Prevention and Lifestyle) program has been implemented to reduce childhood obesity across 20 communities reaching nearly one quarter of the state's population. Staff from across the State come together at regular intervals to share practice challenges and insights and refine the model of practice. Over a 3-year period 12 reflective practice workshops were held with OPAL staff (n = 46). OPAL staff were guided by an external facilitator using inquiring questions to reflect on their health promotion practice within local government. Three themes were identified as central within the reflections. The first theme is shared clarity through the OPAL obesity prevention model highlighting the importance of working to a clearly articulated, holistic obesity prevention model. The second theme is practitioner skill and sensitivity required to implement the model and deal with the 'politics' of obesity prevention. The final theme is the power of relationships as intrinsic to effective community based health promotion. Insights into the daily practices and reflections from obesity prevention practitioners are shared to shed light on the skills required to contribute to individual and social change. OPAL staff co-authored this paper. © The Author 2015. Published by Oxford University Press. All rights reserved. For Permissions, please email: journals.permissions@oup.com.

Thinking and meddling with boundaries: Critical reflections on Matthew Weinstein's narrative of street medics, red-zones and glop

2015-03-01

In pursuit of more mindful notions of hybridity, this review essay provides a series of reflections on Mathew Weinstein's representations of Street Medics and `sciences for the red zones of neoliberalism'. My analysis draws on three popular ways of thinking with boundaries to offer a critical reading of the boundary-work that the essay performs with respect to three dialectics: (1) technical and political; (2) disciplinarily and multidisciplinarities; and (3) structures and agencies. I conclude with reflections on my boundary labour as a researcher, writer and pedagogue and how such cultural work might learn to live better with difference, ambiguities, hybrids and cross-hybrid learning.

Injury and violence prevention policy: celebrating our successes, protecting our future.

Koné, Rebecca Greco; Zurick, Elizabeth; Patterson, Sara; Peeples, Amy

2012-09-01

Policy strategies for injury and violence prevention influence systems development, organizational change, social norms, and individual behavior to improve the health and safety of a population. Injury and violence prevention professionals should consider how their issues resonate with various audiences, including policy makers, the public, and other decision makers. As the cost of healthcare continues to rise and greater demands are placed on the healthcare system, the use of public health policy becomes increasingly critical to protect the public's health and prevent injury and violence and its related morbidities and disabilities (Degutis, 2011). This article highlights some impactful policy successes from the field, allows us to reflect on the Injury Center's 20th anniversary, and describes steps to address injuries and violence into the future. The purpose of this paper is to discuss policy as a public health strategy and the critical role it plays in injury and violence prevention. Published by Elsevier Ltd.

Critical reflections on realist review: insights from customizing the methodology to the needs of participatory research assessment.

2014-06-01

Realist review has increased in popularity as a methodology for complex intervention assessment. Our experience suggests that the process of designing a realist review requires its customization to areas under investigation. To elaborate on this idea, we first describe the logic underpinning realist review and then present critical reflections on our application experience, organized in seven areas. These are the following: (1) the challenge of identifying middle range theory; (2) addressing heterogeneity and lack of conceptual clarity; (3) the challenge of appraising the quality of complex evidence; (4) the relevance of capturing unintended outcomes; (5) understanding the process of context, mechanism, and outcome (CMO) configuring; (6) incorporating middle-range theory in the CMO configuration process; and (7) using middle range theory to advance the conceptualization of outcomes - both visible and seemingly 'hidden'. One conclusion from our experience is that the degree of heterogeneity of the evidence base will determine whether theory can drive the development of review protocols from the outset, or will follow only after an intense period of data immersion. We hope that presenting a critical reflection on customizing realist review will convey how the methodology can be tailored to the often complex and idiosyncratic features of health research, leading to innovative evidence syntheses.

Pressure Injuries in Critical Care: A Survey of Critical Care Nurses.

Cox, Jill; Schallom, Marilyn

2017-10-01

Critical care nurses must be able to skillfully balance the prevention of adverse events such as pressure injuries in an environment with multiple competing and lifesaving technologies that often take precedent. Despite strategies to prevent them, pressure injuries do occur in intensive care unit patients, and consensus is building that some pressure injuries are unavoidable. To determine critical care nurses' attitudes toward prevention of pressure injury and the perceptions of frontline critical care nurses of specific risk factors associated with unavoidable pressure injuries. A descriptive cross-sectional survey design was used. An online survey was posted on the newsletter website of the American Association of Critical-Care Nurses in January 2016. An invitation to participate in the study was emailed to more than 3000 members of the association; 333 nurses responded, for a response rate of approximately 11%. Among the responders, 73% were employed as bedside critical care nurses. More than half (67%) thought that pressure injuries are avoidable, and 66% disagreed that pressure injury prevention was of less interest than other aspects of critical care. The top 2 risk factors for unavoidable pressure injuries were impaired tissue perfusion and impaired tissue oxygenation. Critical care nurses are steadfast stewards of safe patient care and think that pressure injury prevention is a crucial aspect of the care they deliver every day. The findings on risk factors for unavoidable pressure injuries mirrored those of experts and provide a layer of support for these factors. ©2017 American Association of Critical-Care Nurses.

Introduction Critical technological advances have yielded a toolkit of HIV prevention strategies. This literature review sought to provide contextual and historical reflection needed to bridge the conceptual gap between clinical efficacy and community effectiveness (i.e. knowledge and usage) of existing HIV prevention options, especially in resource-poor settings. Methods Between January 2015 and October 2015, we reviewed scholarly and grey literatures to define treatment literacy and health literacy and assess the current need for literacy related to HIV prevention. The review included searches in electronic databases including MEDLINE, PsycINFO, PubMed, and Google Scholar. Permutations of the following search terms were used: “treatment literacy,” “treatment education,” “health literacy,” and “prevention literacy.” Through an iterative process of analyses and searches, titles and/or abstracts and reference lists of retrieved articles were reviewed for additional articles, and historical content analyses of grey literature and websites were additionally conducted. Results and discussion Treatment literacy was a well-established concept developed in the global South, which was later partially adopted by international agencies such as the World Health Organization. Treatment literacy emerged as more effective antiretroviral therapies became available. Developed from popular pedagogy and grassroots efforts during an intense struggle for treatment access, treatment literacy addressed the need to extend access to underserved communities and low-income settings that might otherwise be excluded from access. In contrast, prevention literacy is absent in the recent surge of new biomedical prevention strategies; prevention literacy was scarcely referenced and undertheorized in the available literature. Prevention efforts today include multimodal techniques, which jointly comprise a toolkit of biomedical, behavioural, and structural/environmental approaches

Device-related infections in critically ill patients. Part II: Prevention of ventilator-associated pneumonia and urinary tract infections.

PubMed

Di Filippo, A; De Gaudio, A R

2003-12-01

Device utilization in critically ill patients is responsible for a high risk of complications such as catheter-related bloodstream infections (CRBSI), ventilator-associated pneumonia (VAP) and urinary tract infections (UTI). In this article we will review the current status of data regarding the prevention of VAP and UTI. The results of the more recent (5 years) randomized controlled trials are reviewed and discussed. General recommendations include staff education and use of a surveillance program with a restrictive antibiotic policy. Adequate time must be allowed for hand washing and barrier precautions must always be used during device manipulation. Specific measures for VAP prevention are: 1) use of multi-use, closed-system suction catheters; 2) no routine change of the breathing circuit; 3) lubrication of the cuff of the endotracheal tube (ET) with a water-soluble gel; 4) maintenance of patient in semi-recumbent position to improve chest physiotherapy in intubated patients. Specific measures for UTI prevention include: 1) use of a catheter-valve instead of a standard drainage system; 2) use of a silver-alloy, hydro gel-coated latex urinary catheter instead of uncoated catheters. Biofilm represents a new variable: the capacity of bacteria to organize a biofilm on a device surface can explain the difficulty in preventing and eradicating an infection in a critically ill patient. More clinical trials are needed to verify the efficacy of prevention measures of ICU infections.

The purpose of this paper is to raise awareness of a view of culture as a sociopolitical construction, and to explore implications for incorporating this view into U.S. nursing education and practice. Current definitions of culture, cultural diversity, and cultural competence are examined to highlight ways in which a traditional, essentialist view is reflected. Examples of an alternative, constructivist view are provided through discussion and in a series of questions. These questions serve as the basis for considering new approaches in U.S. nursing education and health care based on view of culture as a dynamic and ever-changing sociopolitical construction.

2018-03-01

The purpose of this study was to determine the effect of caring behaviours on critical thinking and to examine whether self-reflection mediates the effect of caring on critical thinking. We also tested whether caring behaviours moderated the relationship between self-reflection and critical thinking. For this descriptive, correlational, cross-sectional study, we recruited 293 fifth-year nursing students from a junior college in southern Taiwan. Data were collected in 2014 on critical thinking, caring behaviours and self-reflection with insight using the Taiwan Critical Thinking Disposition Inventory, a Chinese version of the Caring Assessment Report Evaluation Q-sort, and a Chinese version of the Self-Reflection and Insight Scale, respectively. Relationships among variables were analysed by structural equation modelling, with the partial least squares method and Sobel test. The results showed that caring behaviours significantly positively affected critical thinking (β = 0.56, t = 12.37, p < 0.001) and self-reflection with insight (β = 0.54, t = 11.99, p < 0.001). Self-reflection and insight significantly positively affected critical thinking (β = 0.34, t = 6.48, p < 0.001). Further, self-reflection and insight mediated the relationship between caring behaviours and critical thinking. Caring behaviours did not, however, moderate the relationship between self-reflection (β = 0.001, t = 0.021, p > 0.05) and critical thinking. Caring behaviours directly affect self-reflection with insight and critical thinking. In addition, caring behaviours also indirectly affect critical thinking through self-reflection and insight. © 2017 Nordic College of Caring Science.

Price, Bob

2015-08-19

Critical thinking and writing are skills that are not easy to acquire. The term 'critical' is used differently in social and clinical contexts. Nursing students need time to master the inquisitive and ruminative aspects of critical thinking that are required in academic environments. This article outlines what is meant by critical thinking in academic settings, in relation to both theory and reflective practice. It explains how the focus of a question affects the sort of critical thinking required and offers two taxonomies of learning, to which students can refer when analysing essay requirements. The article concludes with examples of analytical writing in reference to theory and reflective practice.

2016-01-01

Objective. To evaluate the success of a teaching certificate program by qualitatively evaluating the content and extent of participants’ reflections. Methods. Two investigators independently identified themes within midpoint and final reflection essays across six program years. Each essay was evaluated to determine the extent of reflection in prompted teaching-related topic areas (strengths, weaknesses, assessment, feedback). Results. Twenty-eight themes were identified within 132 essays. Common themes encompassed content delivery, student assessment, personal successes, and challenges encountered. Deep reflection was exhibited, with 48% of essays achieving the highest level of critical reflection. Extent of reflection trended higher from midpoint to final essays, with significant increases in the strengths and feedback areas. Conclusion. The teaching certificate program fostered critical reflection and self-reported positive behavior change in teaching, thus providing a high-quality professional development opportunity. Such programs should strongly consider emphasizing critical reflection through required reflective exercises at multiple points within program curricula. PMID:26941436

What happens in the lab does not stay in the lab [corrected]: Applying midstream modulation to enhance critical reflection in the laboratory.

PubMed

Schuurbiers, Daan

2011-12-01

In response to widespread policy prescriptions for responsible innovation, social scientists and engineering ethicists, among others, have sought to engage natural scientists and engineers at the 'midstream': building interdisciplinary collaborations to integrate social and ethical considerations with research and development processes. Two 'laboratory engagement studies' have explored how applying the framework of midstream modulation could enhance the reflections of natural scientists on the socio-ethical context of their work. The results of these interdisciplinary collaborations confirm the utility of midstream modulation in encouraging both first- and second-order reflective learning. The potential for second-order reflective learning, in which underlying value systems become the object of reflection, is particularly significant with respect to addressing social responsibility in research practices. Midstream modulation served to render the socio-ethical context of research visible in the laboratory and helped enable research participants to more critically reflect on this broader context. While lab-based collaborations would benefit from being carried out in concert with activities at institutional and policy levels, midstream modulation could prove a valuable asset in the toolbox of interdisciplinary methods aimed at responsible innovation.

As the two dimensional version of the functional wavefront manipulation metamaterial, metasurface has become a research hot spot for engineering the wavefront at will with a subwavelength thickness. The wave scattered by the gradient metasurface, which is composed by the periodic supercells, is governed by the generalized Snell's law. However, the critical angle that derived from the generalized Snell's law circles the domain of the incident angles that allow the occurrence of the anomalous reflection and refraction, and no free space scattering waves could exist when the incident angle is beyond the critical angle. Here we theoretically demonstrate that apparent negative reflection can be realized by a gradient acoustic metasurface when the incident angle is beyond the critical angle. The underlying mechanism of the apparent negative reflection is understood as the higher order diffraction arising from the interaction between the local phase modulation and the non-local effects introduced by the supercell periodicity. The apparent negative reflection phenomena has been perfectly verified by the calculated scattered acoustic waves of the reflected gradient acoustic metasurface. This work may provide new freedom in designing functional acoustic signal modulation devices, such as acoustic isolator and acoustic illusion device.

Ethics in nursing education: learning to reflect on care practices.

PubMed

Vanlaere, Linus; Gastmans, Chris

2007-11-01

Providing good care requires nurses to reflect critically on their nursing practices. Ethics education must provide nurses with tools to accomplish such critical reflection. It must also create a pedagogical context in which a caring attitude can be taught and cultivated. To achieve this twofold goal, we argue that the principles of a right-action approach, within which nurses conform to a number of minimum principles, must be integrated into a virtue ethics approach that cultivates a caring attitude. Ethics education that incorporates both the ;critical companionship' method and the use of codes of ethics contributes positively to cultivating critical reflection by nurses.

Despite continuous efforts to retrieve aerosol optical depth (AOD) using a conventional 5-channelmeteorological imager in geostationary orbit, the accuracy in urban areas has been poorer than other areas primarily due to complex urban surface properties and mixed aerosol types from different emission sources. The two largest error sources in aerosol retrieval have been aerosol type selection and surface reflectance. In selecting the aerosol type from a single visible channel, the season-dependent aerosol optical properties were adopted from longterm measurements of Aerosol Robotic Network (AERONET) sun-photometers. With the aerosol optical properties obtained fromthe AERONET inversion data, look-up tableswere calculated by using a radiative transfer code: the Second Simulation of the Satellite Signal in the Solar Spectrum (6S). Surface reflectance was estimated using the clear sky composite method, awidely used technique for geostationary retrievals. Over East Asia, the AOD retrieved from the Meteorological Imager showed good agreement, although the values were affected by cloud contamination errors. However, the conventional retrieval of the AOD over Hong Kong was largely underestimated due to the lack of information on the aerosol type and surface properties. To detect spatial and temporal variation of aerosol type over the area, the critical reflectance method, a technique to retrieve single scattering albedo (SSA), was applied. Additionally, the background aerosol effect was corrected to improve the accuracy of the surface reflectance over Hong Kong. The AOD retrieved froma modified algorithmwas compared to the collocated data measured by AERONET in Hong Kong. The comparison showed that the new aerosol type selection using the critical reflectance and the corrected surface reflectance significantly improved the accuracy of AODs in Hong Kong areas,with a correlation coefficient increase from0.65 to 0.76 and a regression line change from tMI [basic algorithm] = 0

Changing population demographics and immigration patterns have resulted in increasing numbers of Canadians who report speaking a language other than French or English. Inclusion of English-as-a-second-language (ESL) immigrants in cancer education research is critical if disparities in access and use of preventive health care services are to be addressed. This article describes the challenges experienced recruiting and interviewing older ESL immigrant women for a colon cancer prevention study. Factors influencing the recruitment and interview of ESL immigrant women were identified through regular team meetings, interviews, and reflective practice notes. Issues included the importance of community contacts, language barriers, and the motivations of the women for participating. Recommendations for recruitment and inclusion of ESL immigrants in cancer education research are provided.

The aim of this study was to explore the perspectives of Iranian critical care nurses on the barriers to ventilator-associated pneumonia prevention in intensive care units. Most patients hospitalized in intensive care units need mechanical ventilation. One of the most prevalent and serious complications of mechanical ventilation is ventilator-associated pneumonia. There are different barriers to the prevention of this kind of pneumonia. Qualitative descriptive design was used. In this qualitative study, 23 critical care nurses were recruited via purposive sampling. Semi-structured interviews were done for data collection. The interviews were recorded digitally, transcribed word by word, and analyzed using the inductive content analysis approach. The barriers to the prevention of ventilator-associated pneumonia fell into three main categories, namely nurses' limited professional competence, unfavorable environmental conditions, and passive human resource management. The 10 subcategories of these main categories were unfavorable professional attitude, limited professional knowledge, low job motivation, limited professional accountability, non-standard physical structure, inadequate or inappropriate equipment, heavy workload, staff shortage, inadequate staff training, and ineffective supervision. The barriers to the prevention of ventilator-associated pneumonia in intensive care units are very diverse and complex and include a wide range of interrelated personal, environmental, and organizational barriers. This study created a better understanding of the barriers to ventilator-associated pneumonia prevention. Moreover, highlighted the importance of sufficient resources, adequate staffing level, and contextually-appropriate evidence-based guidelines for effective ventilator-associated pneumonia prevention. © 2017 John Wiley & Sons Ltd.

A well-organized, thoughtful study design is essential for creating an impactful study. However, pressures promoting high output from researchers can lead to rushed study proposals that overlook critical weaknesses in the study design that can affect the validity of the conclusions. Researchers can benefit from thorough review of past failed proposals when crafting new research ideas. Conceptual frameworks and root cause analysis are two innovative techniques that can be used during study development to identify flaws and prevent study failures. In addition, conceptual frameworks and root cause analysis can be combined to complement each other to provide both a big picture and detailed view of a study proposal. This article describes these two common analytical methods and provides an example of how they can be used to evaluate and improve a study design by critically examining a previous failed research idea.

Critical Reflectance Derived from MODIS: Application for the Retrieval of Aerosol Absorption over Desert Regions

Aerosols are tiny suspended particles in the atmosphere that scatter and absorb sunlight. Smoke particles are aerosols, as are sea salt, particulate pollution and airborne dust. When you look down at the earth from space sometimes you can see vast palls of whitish smoke or brownish dust being transported by winds. The reason that you can see these aerosols is because they are reflecting incoming sunlight back to the view in space. The reason for the difference in color between the different types of aerosol is that the particles arc also absorbing sunlight at different wavelengths. Dust appears brownish or reddish because it absorbs light in the blue wavelengths and scatters more reddish light to space, Knowing how much light is scattered versus how much is absorbed, and knowin that as a function of wavelength is essential to being able to quantify the role aerosols play in the energy balance of the earth and in climate change. It is not easy measuring the absorption properties of aerosols when they are suspended in the atmosphere. People have been doing this one substance at a time in the laboratory, but substances mix when they are in the atmosphere and the net absorption effect of all the particles in a column of air is a goal of remote sensing that has not yet been completely successful. In this paper we use a technique based on observing the point at which aerosols change from brightening the surface beneath to darkening it. If aerosols brighten a surface. they must scatter more light to space. If they darken the surface. they must be absorbing more. That cross over point is called the critical reflectance and in this paper we show that critical reflectance is a monotonic function of the intrinsic absorption properties of the particles. This parameter we call the single scattering albedo. We apply the technique to MODIS imagery over the Sahara and Sahel regions to retrieve the single scattering albedo in seven wavelengths, compare these retrievals to ground

Preventive HIV/AIDS education through physical education: reflections from Zambia.

PubMed

Njelesani, Donald

2011-01-01

Governments, UN agencies and international and local NGOs have mounted a concerted effort to remobilise sport as a vehicle for broad, sustainable social development. This resonates with the call for sport to be a key component in national and international development objectives. Missing in these efforts is an explicit focus on physical education within state schools, which still enroll most children in the global South. This article focuses on research into one of the few instances where physical education within the national curriculum is being revitalised as part of the growing interest in leveraging the appeal of sport and play as means to address social development challenges such as HIV/AIDS. It examines the response to the Zambian government's 2006 Declaration of Mandatory Physical Education (with a preventive education focus on HIV/AIDS) by personnel charged with its implementation and illustrates weaknesses within the education sector. The use of policy instruments such as decrees/mandates helps ensure the mainstreaming of physical education in development. However, the urgency required to respond to new mandates, particularly those sanctioned by the highest levels of government, can result in critical pieces of the puzzle being ignored, thereby undermining the potential of physical education (and sport) within development.

Service-Learning in Undergraduate Nursing Education: Where is the Reflection?

PubMed

Brown, Janet M; Schmidt, Nola A

2016-01-01

Service-Learning is recognized as a valuable pedagogy that involves experiential learning, reflection, and reciprocal learning. Reflection is a critical component because it assists students to develop critical thinking and social awareness as they reflect upon their experiential learning with community partners. Although there is a proliferation of literature about service-learning, upon closer examination, it is apparent that some authors do not place emphasis on reflection when reporting on service-learning projects. This begs the question, "Where is the reflection?" The purpose of this article is to provide an overview and describe misrepresentations and exemplars of service-learning. After providing an overview of service-learning, examples of how service-learning is misrepresented in the literature are discussed. Exemplars of service-learning are also cited. Calling attention to how service-learning is reported in the literature will increase awareness about the need to critically evaluate articles for evidence of reflection.

The Effects of Coaching Using a Reflective Framework on Early Childhood Science Teachers' Depth of Reflection and Change in Practice

NASA Astrophysics Data System (ADS)

Bloomquist, Debra L.

This embedded-mixed methods study examined if the use of a reflective framework with guiding prompts could support early childhood science teachers in improving their reflective practice and subsequently changing their pedagogy. It further investigated whether type of cognitive coaching group, individual or collaborative, impacted teacher depth of reflection and change in practice. Data included teacher reflections that were rated using the Level of Reflection-On-Action Assessment, reflective codes and inductive themes, as well as videos of participants lessons coded using the SCIIENCE instrument. Findings demonstrated that through guided reflection, teachers developed reflective thinking skills, and through this reflection became more critical and began to improve their pedagogical practice. Further findings supported that collaborative cognitive coaching may not be the most effective professional development for all teachers; as some teachers in the study were found to have difficulty improving their reflectivity and thus their teaching practice. Based on these findings it is recommended that coaches and designers of professional development continue to use reflective frameworks with guiding prompts to support teachers in the reflective process, but take into consideration that coaching may need to be differentiated for the various reflective levels demonstrated by teachers. Future studies will be needed to establish why some teachers have difficulty with the reflective process and how coaches or designers of professional development can further assist these teachers in becoming more critical reflectors.

Reflective journal writing: how it promotes reflective thinking in clinical nursing education: a students' perspective.

Kok, J; Chabeli, M M

According to the outcomes-based education and training system of education (OBET) in the country and the South African Nursing Council, education should focus on "creating" reflective learners and practitioners. This article seeks to determine the effectiveness of reflective journal writing in promoting the reflective thinking of learners in clinical nursing education and to validate the guidelines described in a bigger study on how to facilitate reflective thinking using reflective journal writing. A qualitative, contextual, explorative, descriptive research design was used to determine the learners' perceptions on whether reflective journal writing did promote their higher-level thinking skills during the six-month placement in a psychiatric clinical practice using the reflective diaries. From a population of seventeen fourth-year students, six volunteered to participate in a focus group interview. The data was analysed by means of the descriptive method of open coding of Tesch (in Creswell, 1994:154-156). Positive and negative results from the perceptions of the participants and a literature review served as a basis for deducing and describing guidelines for the effective use of reflective journal writing in promoting reflective thinking in clinical nursing education. The positive perception was the development of problem-solving skills attained through reflection by using analytical critical thinking, synthesis and the evaluation of situations. Self-evaluation leading to intellectual growth and self-awareness indicated a positive perception. Negative perceptions were that reflective journal writing is time consuming, content based with a lack of clear expectations from the teacher, and distrust of students about the information written. Guba's model of ensuring trustworthiness in qualitative research as described in Krefting (1991:215-222) was employed. It is concluded that reflective journal writing in clinical nursing education does promote reflective

Critical theory and its contribution to the nursing discipline.

This article reflects on the Critical theory, stemming from the most important philosophical concepts and the modifications it has endured over time. Thereafter, we expose the contribution of the Critical theory to Nursing. This emphasizes on the contextual analysis of the phenomena and it is a self-critique to prevent dogmatisms and totalitarianisms. It postulates that in order to establish a truth, we must consider the historical conditions within which said truth emerges. Jürgen Habermas, with his Theory of Communicative Action, reorients the original postulates of the Critical theory, making it more coherent from the social point of view, through the Guiding Interests of Knowledge. Nursing professionals who follow the Critical theory highlight the need to improve the description of the construction of knowledge with an emancipating and liberating purpose, which permits Nursing to provide responses to approach reality through a global and dialectic vision and from a democratic position of knowledge, construct research from the social situational reality that is part of its daily experience; everything that can be unified as a "Philosophy of Nursing Care", which should be incorporated onto the professional formation of the discipline and onto the research area.

Making space for belonging: critical reflections on the implementation of personalised adult social care under the veil of meaningful inclusion.

PubMed

Power, Andrew

2013-07-01

This paper critically reflects on the way in which recent adult social care reform has been evolving beneath the alleged policy goal of prioritising the cultivation of meaningful inclusion and 'belonging' in the community. With this goal, there has been a focus away from 'services' for persons with intellectual disabilities, to supporting natural connections within the community. This paper draws on a grounded theory study of the perspectives of those responsible for overseeing community living arrangements for persons with disabilities, drawing on interviews and focus groups with service providers and relevant government officials. It examines the socio-spatial implications of the gradual shift towards 'belonging' as a disability policy goal, as it has evolved in two discrete settings - British Columbia, Canada and Ireland. The findings identify the complexities involved in facilitating active community connection for persons with intellectual disabilities and reveal important cautionary lessons for other jurisdictions where community living policy has arguably been moving away from communal services towards self-managed supports in 'real' communities through personal budgets in an effort to remove barriers to participation. The paper thus critically reflects on the rapid pursuit for transformation in personalised adult social care in government policy, arguing that the process of fostering meaningful community inclusion will and should take time.

In 2010 many of the health disciplines in Australia will be involved in national registration and accreditation, to ensure a more sustainable and flexible health workforce for the future. To this end, in each of the health professions, there is an increasing emphasis on reflective practice and lifelong learning to maintain practice competency. This research focuses on academic teaching and learning in the Pharmacy undergraduate curriculum to develop an indicator tool of graduate practice skills before the student enters the practice internship year. The Graduated Descriptors Competency Tool was developed by means of state, territory, and national stakeholder collaboration. The aim of the project was to assist the scaffolding processes around undergraduate practice teaching and learning. Students on experiential placements have used the tool to demonstrate their current practice skills and the learning required to attain competency during their internship year. Students are guided to develop critical reflection skills for deep understanding and insight into the continued learning and professional development required to maintain long-term health care expertise.

Troubling Muddy Waters: Problematizing Reflective Practice in Global Medical Education.

PubMed

Naidu, Thirusha; Kumagai, Arno K

2016-03-01

The idea of exporting the concept of reflective practice for a global medical education audience is growing. However, the uncritical export and adoption of Western concepts of reflection may be inappropriate in non-Western societies. The emphasis in Western medical education on the use of reflection for a specific end--that is, the improvement of individual clinical practice--tends to ignore the range of reflective practice, concentrating on reflection alone while overlooking critical reflection and reflexivity. This Perspective places the concept of reflective practice under a critical lens to explore a broader view for its application in medical education outside the West. The authors suggest that ideas about reflection in medicine and medical education may not be as easily transferable from Western to non-Western contexts as concepts from biomedical science are. The authors pose the question, When "exporting" Western medical education strategies and principles, how often do Western-trained educators authentically open up to the possibility that there are alternative ways of seeing and knowing that may be valuable in educating Western physicians? One answer lies in the assertion that educators should aspire to turn exportation of educational theory into a truly bidirectional, collaborative exchange in which culturally conscious views of reflective practice contribute to humanistic, equitable patient care. This discussion engages in troubling the already-muddy waters of reflective practice by exploring the global applicability of reflective practice as it is currently applied in medical education. The globalization of medical education demands critical reflection on reflection itself.

Adrenal crisis is a life-threatening emergency that causes significant excess mortality in patients with adrenal insufficiency. Delayed recognition by medical staff of an impending adrenal crisis and failure to give timely hydrocortisone therapy within the emergency department continue to be commonly encountered, even in metropolitan teaching hospitals. Within the authors' institutions, several cases of poorly handled adrenal crises have occurred over the last 2 years. Anecdotal accounts from members of the Addison's support group suggest that these issues are common in Australia. This manuscript is a timely reminder for clinical staff on the critical importance of the recognition, treatment and prevention of adrenal crisis. The manuscript: (i) outlines a case and the clinical outcome of sub-optimally managed adrenal crisis, (ii) summarises the clinical features and acute management of adrenal crisis, (iii) provides recommendations on the prevention of adrenal crisis and (iv) provides guidance on the management of 'sick days' in patients with adrenal insufficiency. © 2016 Royal Australasian College of Physicians.

Service Learning in Undergraduate Nursing Education: Strategies to Facilitate Meaningful Reflection.

PubMed

Schmidt, Nola A; Brown, Janet M

2016-01-01

Service learning is recognized as a valuable pedagogy involving experiential learning, reflection, and reciprocal learning. Students develop critical thinking and social awareness by using the crucial activity of reflecting upon their experiential learning with community partners. The purpose of this paper is to demystify the process of reflection by identifying best practices to enhance reflection and offering suggestions for grading. By understanding "the what" and "the how" of reflection, educators can implement service learning experiences designed to include the essential component of reflection. Strategies for facilitating meaningful reflection are described including descriptions of what students should reflect upon and how to initiate reflection through writing, reading, doing, and telling. Grading rubrics are suggested to facilitate evaluation of student reflection. When properly implemented, service learning encourages students to be good citizens of the world. By using best practices associated with reflection, students can be challenged to think critically about the world and how their service can achieve community goals. Copyright © 2016.

A three-year qualitative study based on an action-research design, framed within the critical genre and using a multi-method approach, was used to establish how a model of critical reflective practice [Van Aswegen, E.J., Brink, H.I., Steyn, P.J., 2000. A model for facilitation of critical reflective practice: Part I- Introductory discussion and explanation of the phases followed to construct the model. Part ll - Conceptual analysis within the context of constructing the model. Part III - Description of the model. Curationis 23 (4), 117-135.] could be implemented. Reflective journals were introduced as one of the educational strategies within the model to support and sustain 'deep' transformatory learning. A component of this larger study focused on how scaffolding deep learning through reflective writing is enhanced by supportive structures. These include critiquing (feedback), a mutually developed self-evaluation strategy, as well as an awareness of and sensitivity to the need for student/writer-responder negotiation. Three student groups of part-time post-basic, practicing South African nurses engaged in reflective writing over the period of an academic year. This article is based on their perceptions, mid-way through their writing, of these strategies. It reflects the story of assumptions made by educators, and challenges for change. Students find reflective writing difficult, and although they are willing to accept its value and engage in the process, they require a regular, specific and sensitive critical response from their writer-responder and follow-up supportive contact. Self-evaluation for the purposes of 'owning' their own ideas is difficult, and requires constant support and validation. Transformatory learning comes at a cost, and a revisiting of the balance of power between student and educator is in order.

2011-09-01

In this paper, I reflect on past papers published in the British Journal of Social Psychology (BJSP) that have played a role in the development of the theory of reasoned action (TRA) and the theory of planned behaviour (TPB). I focus on seven papers that fall into five categories: (1) those that critique the TRA/TPB for taking insufficient account of social factors; (2) those that critique the models on the grounds that many social behaviours are 'habitual'; (3) those that critically examine the construct of perceived behavioural control; (4) those that argue for the importance of affective factors, which appear to be overlooked in the TRA/TPB; and (5) those that argue for the importance of studying the role of moderating factors and interaction effects in the TRA/TPB. I conclude that BJSP's traditional focus on criticism and theory development is one that benefits the journal and the field. ©2011 The British Psychological Society.

To assess the efficacy and safety of esomeprazole in preventing upper gastrointestinal (GI) bleeding in critically ill Chinese patients, using cimetidine as an active comparator. A pre-specified non-inferiority limit (5%) was used to compare rates of significant upper GI bleeding in this randomized, double-blind, parallel-group, phase 3 study across 27 intensive care units in China. Secondary endpoints included safety and tolerability measures. Patients required mechanical ventilation and had at least one additional risk factor for stress ulcer bleeding. Patients were randomized to receive either active esomeprazole 40 mg, as a 30-min intravenous (IV) infusion twice daily, and an IV placebo cimetidine infusion or active cimetidine 50 mg/h, as a continuous infusion following an initial bolus of 300 mg, and placebo esomeprazole injections, given up to 14 days. Patients were blinded using this double-dummy technique. Of 274 patients, 2.7% with esomeprazole and 4.6% with cimetidine had significant upper GI bleeding (bright red blood in the gastric tube not clearing after lavage or persistent Gastroccult-positive "coffee grounds" material). Non-inferiority of esomeprazole to cimetidine was demonstrated. The safety profiles of both drugs were similar and as expected in critically ill patients. Esomeprazole is effective in preventing upper GI bleeding in critically ill Chinese patients, as demonstrated by the non-inferiority analysis using cimetidine as an active control.

The global population of wild tigers remains dangerously low at fewer than 3500 individuals. Habitat loss, along with poaching, can undermine the international target recovery of doubling the number of wild tigers by 2022. Using a new satellite-based monitoring system, we analyzed 14 years of forest loss data within the 76 landscapes (ranging from 278 to 269,983 km(2)) that have been prioritized for conservation of wild tigers. Our analysis provides an update of the status of tiger habitat and describes new applications of technology to detect precisely where forest loss is occurring in order to curb future habitat loss. Across the 76 landscapes, forest loss was far less than anticipated (79,597 ± 22,629 km(2), 7.7% of remaining habitat) over the 14-year study period (2001-2014). Habitat loss was unevenly distributed within a subset of 29 landscapes deemed most critical for doubling wild tiger populations: 19 showed little change (1.5%), whereas 10 accounted for more than 98% (57,392 ± 16,316 km(2)) of habitat loss. Habitat loss in source population sites within 76 landscapes ranged from no loss to 435 ± 124 km(2) ([Formula: see text], SD = 89, total = 1676 ± 476 km(2)). Doubling the tiger population by 2022 requires moving beyond tracking annual changes in habitat. We highlight near-real-time forest monitoring technologies that provide alerts of forest loss at relevant spatial and temporal scales to prevent further erosion.

Narrating practice: reflective accounts and the textual construction of reality.

Taylor, Carolyn

Two approaches dominate current thinking in health and welfare: evidence-based practice and reflective practice. Whilst there is debate about the merits of evidence-based practice, reflective practice is generally accepted with critical debate as an important educational tool. Where critique does exist it tends to adopt a Foucauldian approach, focusing on the surveillance and self-regulatory aspects of reflective practice. This article acknowledges the critical purchase on the concept of reflective practice offered by Foucauldian approaches but argues that microsociological and discourse analytic approaches can further illuminate the subject and thus serve as a complement to them. The claims of proponents of reflective practice are explored, in opposition to the technical-rational approach of evidence-based practice. Reflective practice tends to adopt a naive or romantic realist position and fails to acknowledge the ways in which reflective accounts construct the world of practice. Microsociological approaches can help us to understand reflective accounts as examples of case-talk, constructed in a narrative form in the same way as case records and presentations.

Usually, the reflection probability R(E) of a particle of zero energy incident on a potential which converges to zero asymptotically is found to be 1: R(0)=1. But earlier, a paradoxical phenomenon of zero reflection at zero energy (R(0)=0) has been revealed as a threshold anomaly. Extending the concept of half-bound state (HBS) of 3D, here we show that in 1D when a symmetric (asymmetric) attractive potential well possesses a zero-energy HBS, R(0)=0 (R(0)\\ll 1). This can happen only at some critical values q c of an effective parameter q of the potential well in the limit E\\to {0}+. We demonstrate this critical phenomenon in two simple analytically solvable models: square and exponential wells. However, in numerical calculations, even for these two models R(0)=0 is observed only as extrapolation to zero energy from low energies, close to a precise critical value q c. By numerical investigation of a variety of potential wells, we conclude that for a given potential well (symmetric or asymmetric), we can adjust the effective parameter q to have a low reflection at a low energy.

Nursing students' reflections on racism.

Schaefer, Karen Moore

2008-01-01

Racism is the systematic oppression of people of color at personal/interpersonal, institutional, and/or cultural levels. Discussions about racism often become emotional and personal. A discussion related to the accurate labeling of students on the basis of their heritage in an undergraduate professional issues class became emotionally charged. To prevent any further escalation of emotions, the author brought closure by asking students to read and write a reflective response to the Black Prayer. This article is a summary of urban nursing students' reflections and how giving voice to such reflections is a way of opening the door to frank discussions of racism and its effects.

Language as a constitutive: critical thinking for multicultural education and practice in the 21st century.

PubMed

Phillips, D A

2000-11-01

Postmodern understandings of language can function as revolutionary critical thinking tools and enable multicultural education in a way yet to be resolutely embraced by the discipline. This thesis is illustrated with critical thinking examples relevant to topics in nursing education, such as maternal infant attachment, HIV prevention education, standardized instruments measuring quality of life and self-esteem, domain of person, and adolescent male identity formation. Working through postmodern positions on language produces important questions. It offers nursing provocative ways of thinking about education and provides radically different approaches to critical thinking and cultural competence. Capitalizing on postmodern sensibilities about language to create multicultural education and practice will take persistent self-reflective educational practices that question the ground that nursing stands on, as well as good intentions regarding a deep and broad embrace of complexly understood cultural competence.

Chronic obstructive pulmonary disease (COPD) is the third leading cause of death and is a substantial source of disability in the United States. Moderate-to-severe acute exacerbations of COPD (AECOPD) can progress to respiratory failure, necessitating ventilator assistance in patients in the intensive care unit (ICU). Patients in the ICU with AECOPD requiring ventilator support have higher morbidity and mortality rates as well as costs compared with hospitalized patients not in the ICU. The mainstay of management for patients with AECOPD in the ICU includes ventilator support (noninvasive or invasive), rapid-acting inhaled bronchodilators, systemic corticosteroids, and antibiotics. However, evidence supporting these interventions for the treatment of AECOPD in critically ill patients admitted to the ICU is scant. Corticosteroids have gained widespread acceptance in the management of patients with AECOPD necessitating ventilator assistance, despite their lack of evaluation in clinical trials as well as controversies surrounding optimal dosage regimens and duration of treatment. Recent studies evaluating the safety and efficacy of corticosteroids have found that higher doses are associated with increased adverse effects, which therefore support lower dosing strategies, particularly for patients admitted to the ICU for COPD exacerbations. This review highlights recent findings from the current body of evidence on nonpharmacologic and pharmacologic treatment and prevention of AECOPD in critically ill patients. In addition, the administration of bronchodilators using novel delivery devices in the ventilated patient and the conflicting evidence surrounding antibiotic use in AECOPD in the critically ill is explored. Further clinical trials, however, are warranted to clarify the optimal pharmacotherapy management for AECOPD, particularly in critically ill patients admitted to the ICU. © 2015 Pharmacotherapy Publications, Inc.

Dunn, Louise; Musolino, Gina M

Facilitation of reflective practice is critical for the ongoing demands of health care practitioners. Reflective thinking concepts, grounded in the work of Dewey and Schön, emphasize critical reflection to promote transformation in beliefs and learning necessary for reflective practice. The Reflective Thinking Questionnaire (QRT) and Revised Study Process Questionnaire (RSPQ-2F) assess skill aspects of professional reasoning, with promise for measuring changes over time. The purpose of this study was to examine the reliability and responsiveness and the model validity of reflective thinking and approaches to learning measures for U.S. health professions students enrolled in entry-level occupational (MOT) and physical therapy (DPT) programs. This measurement study addressed reliability and responsiveness of two measures, the QRT and RSPQ-2F, for graduate health professionals. A convenience sample of 125 MOT and DPT students participated in the two-measure, test-retest investigation, with electronic data collection. Outcomes support the stability of the four-scale QRT (ICC 0.63 to 0.82) and the two-scale RSPQ-2F (ICC 0.91 and 0.87). Descriptive data supporting responsiveness are presented. With noted limitations, the results support the use of the QRT and RSPQ-2F measures to assess changes in reflective thinking and approaches to learning. Measurement of these learning outcomes furthers our understanding and knowledge about instructional strategies, development of professional reasoning, and fostering of self-directed learning within MOT and DPT programs.

Critical friends: A way to develop preceptor competence?

PubMed

Carlson, Elisabeth

2015-11-01

Preceptorship entails for nurses to create a supportive learning and working climate where students or newcomers are given opportunities to develop professional competence. However, being a skilled and experienced nurse does not automatically turn the professional into a skilled educator as teaching of a subject is a whole different story. Preceptors need to continuously and critically reflect on their practices in order to facilitate the development of professional pedagogical competence. Critical friends are colleagues with comparable educational background evaluating the work of each other. The relationship should rely on friendship and mutual trust, adding new dimensions to the reflective process. Being engaged in a critical friendship allows the "friends" to become aware of their own shortcomings which can then be reflected on in relation to clinical as well as pedagogical practices. Being and having a critical friend might be one promising way forward for preceptors to develop pedagogical and professional competence. Copyright © 2014 Elsevier Ltd. All rights reserved.

Analytical study of the reflection and transmission coefficient of the submarine interface

Zhang, Guangli; Hao, Chongtao; Yao, Chen

2018-05-01

The analytical study of the reflection and transmission coefficient of the seafloor interface is essential for the characterization of the ocean bottom in marine seismic exploration. Based on the boundary conditions of the seafloor interface, the analytical expression of the reflection and transmission coefficient at the submarine interface is derived in this study by using the steady-state wave solution of the elastic wave in a homogeneous, isotropic medium. With this analytical expression, the characteristics of the reflection and transmission coefficient at the submarine interface are analysed and discussed using critical angles. The results show that the change in the reflection and transmission coefficient with the incidence angle presents a "segmented" characteristic, in which the critical angle is the dividing point. The amplitude value and phase angle of the coefficient at the submarine interface change dramatically at the critical angle, which is related to the P- and S-wave velocities in the seabed layer. Compared with the stiff seabed, the soft seabed has a larger P-wave critical angle and an absence of the converted S-wave critical angle, owing to the low P- and S-wave velocities in the solid seabed layer. By analysing and discussing the special changes that occur in the coefficient values at the critical angle, the reflection and transmission characteristics of the different incident angles are obtained. Synthetic models of both stiff and soft seafloors are provided in this study to verify the analytical results. Finally, we compared our synthetic results with real data from the Gulf of Mexico, which enabled the validation of our conclusions.

Critical behavior of the order-disorder phase transition in β -brass investigated by x-ray scattering

β -brass exhibits an archetypical example of an order-disorder transition with a critical behavior that was previously investigated by neutron scattering. The data were well described by the three-dimensional (3d) Ising model but the relatively crude experimental resolution prevented an in-depth examination of the single-length scaling hypothesis, a cornerstone in the theory of critical phenomena. With the development of synchrotron x-ray experiments, high-resolution data could be recorded and surprisingly it was found that the single-length scaling did not hold in most critical systems, possibly due to strain originating from surface defects and/or impurities. In this paper we demonstrate single-length critical behavior using high-resolution x-ray scattering in β -brass. The investigations confirm that β -brass behaves like a 3d Ising system over a wide range of length scales comprising correlated clusters of millions of atoms. To vary the surface sensitivity, experiments have been performed both in Bragg reflection and Laue transmission geometries but without any substantial differences observed in the scaling and critical behavior.

The approach to reflection x-ray microscopy below the critical angles

Artyukov, Igor A.; Busarov, Alexander; Popov, Nikolay L.; Vinogradov, Alexander V.

2017-05-01

There is a quest for new knowledge and methods to study various materials and processes on surfaces and interfaces at the nanoscale. It concerns ablation, phase transitions, physical and chemical transformations, dissolution, selforganization etc. Obviously, to achieve an appropriate resolution it is necessary to use a corresponding wavelength . Higher resolution can be obtained with shorter wavelengths. On the other hand, in surface modification, ablation, study of buried interfaces etc. the penetration length of radiation into the materials, which depends on the wavelength and angle of incidence, plays important role... Considering these factors the experimental studies in nano-physics and nanotechnology are usually carried out using X-ray radiation with a photon energy of 0.1-10 keV. As far as surfaces and films are investigated, it is reasonable to use an X-ray microscope operating in the reflection mode. However, in this spectral range a substantial portion of the radiation is reflected only at small grazing angles (e.g. <= 10°). Thus, the idea of grazing incidence reflection-mode X-ray microscope has been developed. In this paper, we consider one of possible schemes of such an X-ray microscope. Our analysis and simulation is based on the extension of the Fresnel propagation theory to tilted object problems.

BACKGROUND Chart review represents a critical cornerstone for practice-based learning and improvement in our internal medicine residency program. OBJECTIVE To document residents’ performance monitoring and improvement skills in their continuity clinics, their satisfaction with practice-based learning and improvement, and their ability to self-reflect on their performance. DESIGN Retrospective longitudinal design with repeated measures. PARTICIPANTS Eighty Internal Medicine residents abstracted data for 3 consecutive years from the medical records of their 4,390 patients in the University of Wisconsin-Madison (UW) Hospital and Clinics and William S. Middleton Veterans Administration (VA) outpatient clinics. MEASUREMENT Logistic modeling was used to determine the effect of postgraduate year, resident sex, graduation cohort, and clinic setting on residents’ “compliance rate” on 17 nationally recognized health screening and chronic disease management parameters from 2003 to 2007. RESULTS Residents’ adherence to national preventive and chronic disease standards increased significantly from intern to subsequent years for administering immunizations, screening for diabetes, cholesterol, cancer, and behavioral risks, and for management of diabetes. Of the residents, 92% found the chart review exercise beneficial, with 63% reporting gains in understanding about their medical practices, 26% reflecting on specific gaps in their practices, and 8% taking critical action to improve their patient outcomes. CONCLUSIONS This paper provides support for the feasibility and practicality of this limited-cost method of chart review. It also directs our residency program’s attention in the continuity clinic to a key area important to internal medicine training programs by highlighting the potential benefit of enhancing residents’ self-reflection skills.

The recruitment of asymptomatic volunteers has been identified as a critical factor that is delaying the development and validation of preventive therapies for Alzheimer disease (AD). Typical recruitment strategies involve the use of convenience samples or soliciting participation of older adults with a family history of AD from clinics and outreach efforts. However, high-risk groups, such as ethnic/racial minorities, are traditionally less likely to be recruited for AD prevention studies, thus limiting the ability to generalize findings for a significant proportion of the aging population. A community-engagement approach was used to create a registry of 2311 research-ready, healthy adult volunteers who reflect the ethnically diverse local community. Furthermore, the registry's actual commitment to research was examined, through demonstrated participation rates in a clinical study. The approach had varying levels of success in establishing a large, diverse pool of individuals who are interested in participating in pharmacological prevention trials and meet the criteria for primary prevention research trials designed to delay the onset of AD. Our efforts suggest that entry criteria for the clinical trials need to be carefully considered to be inclusive of African Americans, and that sustained effort is needed to engage African Americans in pharmacological prevention approaches.

Do screening-preventative interventions in asymptomatic pregnancies reduce the risk of preterm delivery--a critical appraisal of the literature.

PubMed

Varma, Rajesh; Gupta, Janesh K; James, David K; Kilby, Mark D

2006-08-01

Recent research has suggested that women who experience preterm delivery (PTD) may be identified earlier in pregnancy and before onset of symptoms. Interventions commenced at this earlier asymptomatic stage may offer an opportunity to prevent PTD or lengthen gestation sufficiently to reduce adverse perinatal outcome. Our objective was to examine the evidence that supports or refutes this approach to preventing PTD. We therefore conducted a systematic search and critical appraisal of the identified literature. We found evidence that introducing screening-preventative strategies for asymptomatic pregnancies may reduce the rate of PTD. Evidence for screening and selective treatment exists for: asymptomatic bacteriuria; bacterial vaginosis in low-risk population groups; elective cervical cerclage in high-risk pregnancies; indicated cervical cerclage in women with short cervical length on ultrasound; prophylactic progesterone supplementation in high-risk pregnancies, and smoking cessation. However, for most other strategies, such as increased antenatal attendance, or routine administration of prophylactic micronutrients, the evidence is inconsistent and conflicting. Information on neonatal outcomes apart from PTD (such as serious neonatal morbidity and mortality) was found to be lacking in most studies. It was therefore not possible to establish whether preventing PTD or prolonging gestation would correlate to improved perinatal outcome, and this lessened the potential clinical usefulness of any proposed preventative strategy. No studies were found that evaluated the effectiveness of combining screening-preventative strategies. The review concludes with a suggested an antenatal management plan designed to prevent PTD based on current practice and the evidence presented in this article.

Understanding the Nature of Science Through a Critical and Reflective Analysis of the Controversy Between Pasteur and Liebig on Fermentation

García-Carmona, Antonio; Acevedo-Díaz, José Antonio

2017-03-01

This article presents a qualitative study, descriptive-interpretive in profile, of the effectiveness in learning about the nature of science (NOS) of an activity relating to the historical controversy between Pasteur and Liebig on fermentation. The activity was implemented during a course for pre-service secondary science teachers (PSSTs) specializing in physics and chemistry. The approach was explicit and reflective. Three research questions were posed: (1) What conceptions of NOS do the PSSTs show after a first reflective reading of the historical controversy?, (2) What role is played by the PSSTs' whole class critical discussion of their first reflections on the aspects of NOS dealt with in the controversy?, and (3) What changes are there in the PSSTs' conceptions of NOS after concluding the activity? The data for analysis was extracted from the PSSTs' group reports submitted at the end of the activity and the audio-recorded information from the whole class discussion. A rubric was prepared to assess this data by a process of inter-rater analysis. The results showed overall improvement in understanding the aspects of NOS involved, with there being a significant evolution in some cases (e.g., conception of scientific theory) and moderate in others (e.g., differences in scientific interpretations of the same phenomenon). This reveals that the activity has an educational utility for the education of PSSTs in NOS issues. The article concludes with an indication of some educational implications of the experience.

Euclidean mirrors: enhanced vacuum decay from reflected instantons

NASA Astrophysics Data System (ADS)

Akal, Ibrahim; Moortgat-Pick, Gudrid

2018-05-01

We study the tunnelling of virtual matter–antimatter pairs from the quantum vacuum in the presence of a spatially uniform, time-dependent electric background composed of a strong, slow field superimposed with a weak, rapid field. After analytic continuation to Euclidean spacetime, we obtain from the instanton equations two critical points. While one of them is the closing point of the instanton path, the other serves as an Euclidean mirror which reflects and squeezes the instanton. It is this reflection and shrinking which is responsible for an enormous enhancement of the vacuum pair production rate. We discuss how important features of two different mechanisms can be analysed and understood via such a rotation in the complex plane. (a) Consistent with previous studies, we first discuss the standard assisted mechanism with a static strong field and certain weak fields with a distinct pole structure in order to show that the reflection takes place exactly at the poles. We also discuss the effect of possible sub-cycle structures. We extend this reflection picture then to weak fields which have no poles present and illustrate the effective reflections with explicit examples. An additional field strength dependence for the rate occurs in such cases. We analytically compute the characteristic threshold for the assisted mechanism given by the critical combined Keldysh parameter. We discuss significant differences between these two types of fields. For various backgrounds, we present the contributing instantons and perform analytical computations for the corresponding rates treating both fields nonperturbatively. (b) In addition, we also study the case with a nonstatic strong field which gives rise to the assisted dynamical mechanism. For different strong field profiles we investigate the impact on the critical combined Keldysh parameter. As an explicit example, we analytically compute the rate by employing the exact reflection points. The validity of the predictions

Critical Factors for Successful Practice of Disaster-Resilient Community in Urban City

Chou, J. S.; Wu, J. H.

2017-12-01

Due to special geographical environment, Taiwan is a natural disaster-prone area, which often suffers from earthquakes, typhoons and other natural hazards, resulting in heavy casualties and huge property losses. Furthermore, effect of global warming increases extreme climate events and leads to frequent and severe natural disasters. Therefore, disaster prevention and response are not only an important issue of government policy, but also a critical issue of people's life. Rather than over-reliance on government assistance, the spontaneous participation and co-operation by people can complete specific disaster preparedness and reinforce local energy of disaster prevention and response. Although the concept of disaster-resilient community (DRC) has been shaped for a period of time, residents in the community cannot keep up the pace with government, which may decrease the effectiveness of DRC development. Thus, the study of theory and practice of urban DRC becomes an imperative need. This article is a qualitative case study, which uses the participant observation and self-reflection in action research methods to collect relevant information for empirical validation. Particularly, this investigation is supplemented by service work experience in DRC promotion conducted by the researchers. According to the qualitative analyses of case communities during training process of disaster prevention and preparedness, we can identify the critical factors affecting the level of community-based disaster prevention and protection works. Based on the literature and empirical supports, the factors are discussed through three spindle constructs respectively, namely coping strategy, operations management and organizational behavior. Based on the findings of this study, we make conclusions and suggestions for related authority in sustainably promoting DRC.

Intrahospital transportation of critically ill patients is associated with significant complications. In order to reduce overall risk to the patient, such transports should well organized, efficient, and accompanied by the proper monitoring, equipment, and personnel. Protocols and guidelines for patient transfers should be utilized universally across all healthcare facilities. Care delivered during transport and at the site of diagnostic testing or procedure should be equivalent to the level of care provided in the originating environment. Here we review the most common problems encountered during transport in the hospital setting, including various associated adverse outcomes. Our objective is to make medical practitioners, nurses, and ancillary health care personnel more aware of the potential for various complications that may occur during patient movement from the intensive care unit to other locations within a healthcare facility, focusing on risk reduction and preventive strategies.

Described is a device having an anti-reflection surface. The device comprises a silicon substrate with a plurality of silicon spikes formed on the substrate. A first metallic layer is formed on the silicon spikes to form the anti-reflection surface. The device further includes an aperture that extends through the substrate. A second metallic layer is formed on the substrate. The second metallic layer includes a hole that is aligned with the aperture. A spacer is attached with the silicon substrate to provide a gap between an attached sensor apparatus. Therefore, operating as a Micro-sun sensor, light entering the hole passes through the aperture to be sensed by the sensor apparatus. Additionally, light reflected by the sensor apparatus toward the first side of the silicon substrate is absorbed by the first metallic layer and silicon spikes and is thereby prevented from being reflected back toward the sensor apparatus.

Evidence of a shared purpose, critical reflection, innovation and leadership in interprofessional healthcare teams: a realist synthesis.

PubMed

Sims, Sarah; Hewitt, Gillian; Harris, Ruth

2015-05-01

Realist synthesis is a theory-driven approach for evaluating complex interventions using empirical evidence, which seeks an explanatory analysis of who a complex intervention works for, how, why, and in what circumstances. Interprofessional teamworking in healthcare is one such complex intervention, as teams are influenced by social and organizational factors, which makes them highly variable and context dependent. This article concludes a series of four articles that report on a realist synthesis of interprofessional teamworking. The synthesis identified 13 mechanisms that are reported in the literature to be the underlying processes through which interprofessional teamworking produces its effects. This article explores four of these mechanisms: a shared purpose; critical reflection; innovation; and leadership. These mechanisms together explain how a team sets and maintains its focus and direction. This article highlights that whilst many assumptions are made within the healthcare literature about how these mechanisms operate within teams, these assumptions are not always founded upon strong empirical evidence.

Improving access to mental health care in an Orthodox Jewish community: a critical reflection upon the accommodation of otherness.

The English National Health Service (NHS) has significantly extended the supply of evidence based psychological interventions in primary care for people experiencing common mental health problems. Yet despite the extra resources, the accessibility of services for 'under-served' ethnic and religious minority groups, is considerably short of the levels of access that may be necessary to offset the health inequalities created by their different exposure to services, resulting in negative health outcomes. This paper offers a critical reflection upon an initiative that sought to improve access to an NHS funded primary care mental health service to one 'under-served' population, an Orthodox Jewish community in the North West of England. A combination of qualitative and quantitative data were drawn upon including naturally occurring data, observational notes, e-mail correspondence, routinely collected demographic data and clinical outcomes measures, as well as written feedback and recorded discussions with 12 key informants. Improvements in access to mental health care for some people from the Orthodox Jewish community were achieved through the collaborative efforts of a distributed leadership team. The members of this leadership team were a self-selecting group of stakeholders which had a combination of local knowledge, cultural understanding, power to negotiate on behalf of their respective constituencies and expertise in mental health care. Through a process of dialogic engagement the team was able to work with the community to develop a bespoke service that accommodated its wish to maintain a distinct sense of cultural otherness. This critical reflection illustrates how dialogic engagement can further the mechanisms of candidacy, concordance and recursivity that are associated with improvements in access to care in under-served sections of the population, whilst simultaneously recognising the limits of constructive dialogue. Dialogue can change the dynamic of

Venous thromboembolism is difficult to diagnose in critically ill patients and may increase morbidity and mortality. To evaluate the cost-effectiveness of strategies to reduce morbidity from venous thromboembolism in critically ill patients. A Markov decision analytic model to compare weekly compression ultrasound screening (screening) plus investigation for clinically suspected deep vein thrombosis (DVT) (case finding) versus case finding alone; and a hypothetical program to increase adherence to DVT prevention. Probabilities were derived from a systematic review of venous thromboembolism in medical-surgical intensive care unit patients. Costs (in 2010 $US) were obtained from hospitals in Canada, Australia, and the United States, and the medical literature. Analyses were conducted from a societal perspective over a lifetime horizon. Outcomes included costs, quality-adjusted life-years (QALY), and incremental cost-effectiveness ratios. In the base case, the rate of proximal DVT was 85 per 1,000 patients. Screening resulted in three fewer pulmonary emboli than case-finding alone but also two additional bleeding episodes, and cost $223,801 per QALY gained. In sensitivity analyses, screening cost less than $50,000 per QALY only if the probability of proximal DVT increased from a baseline of 8.5-16%. By comparison, increasing adherence to appropriate pharmacologic thromboprophylaxis by 10% resulted in 16 fewer DVTs, one fewer pulmonary emboli, and one additional heparin-induced thrombocytopenia and bleeding event, and cost $27,953 per QALY gained. Programs achieving increased adherence to best-practice venous thromboembolism prevention were cost-effective over a wide range of program costs and were robust in probabilistic sensitivity analyses. Appropriate prophylaxis provides better value in terms of costs and health gains than routine screening for DVT. Resources should be targeted at optimizing thromboprophylaxis.

Promoting cognitive and metacognitive reflective reasoning skills in nursing practice: self-regulated learning theory.

Kuiper, Ruth Anne; Pesut, Daniel J

2004-02-01

Effective clinical reasoning in nursing practice depends on the development of both cognitive and metacognitive skills. While a number of strategies have been implemented and tested to promote these skills, educators have not been able consistently to predict their development. Self-regulated learning theory suggests that this development requires concurrent attention to both the cognitive and metacognitive dimensions of reasoning in nursing care contexts. This paper reports on a study to explore the impact of self-regulated learning theory on reflective practice in nursing, and to advance the idea that both cognitive and metacognitive skills support the development of clinical reasoning skills. Integrative review of published literature in social science, educational psychology, nursing education, and professional education using the Cumulative Index to Nursing and Allied Health (CINAHL), Educational Resource Information Center (ERIC), and American Psychological Association (PsychInfo) Databases. The search included all English language articles with the key words clinical reasoning, cognition, critical thinking, metacognition, reflection, reflective practice, self-regulation and thinking. Reflective clinical reasoning in nursing practice depends on the development of both cognitive and metacognitive skill acquisition. This skill acquisition is best accomplished through teaching-learning attention to self-regulation learning theory. A critical analysis of the literature in the areas of critical thinking and reflective practice are described as a background for contemporary work with self-regulated learning theory. It is apparent that single-minded attention to critical thinking, without attention to the influence of metacognition or reflection, is but one perspective on clinical reasoning development. Likewise, single-minded attention to metacognition or reflection, without attention to the influence of critical thinking, is another perspective on clinical

Implementation of critical care response team.

Analyses of hospital deaths have indicated that a significant proportion of the reported deaths might have been prevented had the patients received intensive level care early enough. Over the past few decades the critical care response team has become an important means of preventing these deaths. As the proactive arm of intensive care delivery, the critical care response team places emphasis on early identification of signs of clinical deterioration, which then prompts the mobilization of intensive care brought right to the patient's bedside. However, the setting up of a critical care response team is a difficult undertaking involving different levels of cooperation between all service stakeholders, and a bringing together of professional expertise and experience in its operations. The implementation of a critical care response team often involves a high-level restructuring of a hospital's service orientation. In the present work, the various factors and different models to be considered in implementing a critical care response team are addressed.

The Surface Hold Advisor Using Critical Sections is a system and method for providing hold advisories to surface controllers to prevent gridlock and resolve crossing and merging conflicts among vehicles traversing a vertex-edge graph representing a surface traffic network on an airport surface. The Advisor performs pair-wise comparisons of current position and projected path of each vehicle with other surface vehicles to detect conflicts, determine critical sections, and provide hold advisories to traffic controllers recommending vehicles stop at entry points to protected zones around identified critical sections. A critical section defines a segment of the vertex-edge graph where vehicles are in crossing or merging or opposite direction gridlock contention. The Advisor detects critical sections without reference to scheduled, projected or required times along assigned vehicle paths, and generates hold advisories to prevent conflicts without requiring network path direction-of-movement rules and without requiring rerouting, rescheduling or other network optimization solutions.

The intensity of the sunlight reflected by the snow-covered surfaces is so high that it may disturb humans many times. This study aims to determine the reflected sunlight intensities from snow covered areas at points near (at a distance of 2 m) and under an individual tree and among trees (in the forest area) by accepting the open area as control; the reducing effects of the plant materials on reflected sunlight in percentage by comparing with the values of the open (control) area; and critical reflected sunlight threshold values for human visual comfort. The study was carried out over 22 clear and calm, i.e. sky was cloudless and wind was calm, days between the 1st and 31st days of January 2004, at 8:30 in the morning, at 12:30 at noon and at 14:30 in the afternoon in Erzurum. In order to determine the discomforting light intensity levels, 25 females and 26 male (totally 51) student subjects whose mean age was 20 and who had no visual disorders were selected. Considering the open area as control, mean reflected sunlight reducing effects were found to be 19.0, 66.0 and 82.7% for the 2 m near a tree, under a tree, and forest area, respectively. According to the responses of 51 subjects in the study, visually "very comfortable" range is between 5,000 and 8,000 lx; "comfortable" range is between 11,000 and 75,000 lx (mostly at 12,000 lx); "uncomfortable" condition is above the light intensity value of 43,000 lx and "very uncomfortable" condition is above the intensity of 80,000 lx. Great majority of the subjects (91%) found the value of 103,000 lx to be "very uncomfortable." As it is not an applicable way to use the great and dense tree masses in the cities, at least individual trees should be used along the main pedestrian axels in the cities having the same features with Erzurum to prevent the natural light pollution and discomforting effects of the snow-reflected sunlight.

Falling has high incidence and reoccurrence rates and is an essential factor contributing to accidental injury or death for older adults. Enhancing the participation of community-dwelling older adults in fall-prevention programs is crucial. Understanding fall-prevention beliefs will be beneficial for developing a community-based fall-prevention program. The aim of the present study was to identify the distinct types of subjective views on the fall-prevention beliefs of community-dwelling older adults aged 80 years and older by applying the Q method. The Q method was adopted to investigate the pattern of perception on fall-prevention beliefs. Forty-two older adults aged 80 - 92 years from a community care center in Northern Taiwan were recruited and requested to complete a Q-sorting. A series of Q-sorts was performed by the participants to rank 30 statements into a normal distribution Q-sort grid. The Q-sorts were subjected to principal component analysis by using PQMethod software Version 2.35. Four statistically independent perspectives were derived from the analysis and reflected distinct viewpoints on beliefs related to fall prevention. Participants in the Considerate perspective believed that health problems caused by falling were serious and fall prevention could decrease the burden they place on their family. Participants in the Promising perspective believed that existing health problems could cause a fall and that fall prevention contributed to their well-being. Participants in the Adaptable perspective perceived low barriers to execute fall prevention and displayed self-confidence and independence in preventing falls. Participants in the Ignorance perspective believed that they could not prevent falls and perceived barriers to fall prevention. By combining theoretical constructs and the Q methodology approach, this study identified four distinct perspectives on fall prevention among community-dwelling older adults.

Objective Colorectal cancer (CRC) leads to significant morbidity/mortality worldwide. Defining critical research gaps (RG), their prioritisation and resolution, could improve patient outcomes. Design RG analysis was conducted by a multidisciplinary panel of patients, clinicians and researchers (n=71). Eight working groups (WG) were constituted: discovery science; risk; prevention; early diagnosis and screening; pathology; curative treatment; stage IV disease; and living with and beyond CRC. A series of discussions led to development of draft papers by each WG, which were evaluated by a 20-strong patient panel. A final list of RGs and research recommendations (RR) was endorsed by all participants. Results Fifteen critical RGs are summarised below: RG1: Lack of realistic models that recapitulate tumour/tumour micro/macroenvironment; RG2: Insufficient evidence on precise contributions of genetic/environmental/lifestyle factors to CRC risk; RG3: Pressing need for prevention trials; RG4: Lack of integration of different prevention approaches; RG5: Lack of optimal strategies for CRC screening; RG6: Lack of effective triage systems for invasive investigations; RG7: Imprecise pathological assessment of CRC; RG8: Lack of qualified personnel in genomics, data sciences and digital pathology; RG9: Inadequate assessment/communication of risk, benefit and uncertainty of treatment choices; RG10: Need for novel technologies/interventions to improve curative outcomes; RG11: Lack of approaches that recognise molecular interplay between metastasising tumours and their microenvironment; RG12: Lack of reliable biomarkers to guide stage IV treatment; RG13: Need to increase understanding of health related quality of life (HRQOL) and promote residual symptom resolution; RG14: Lack of coordination of CRC research/funding; RG15: Lack of effective communication between relevant stakeholders. Conclusion Prioritising research activity and funding could have a significant impact on reducing CRC

The high number of divorces could partly be attributed to a lack of sexual desire in the couples linked to the prevailing sexual hyperstimulation in society. Sexual harassment on the internet and the exposition of abuse incidents in the mass media contribute to the increased numbers of child sexual abuse. Enhanced awareness among adults about the potential dangers of television and the internet, as well as psychotherapeutic treatment of abusers and their victims would be of preventative importance. Psychotherapeutic treatment of adolescents in situations of developmental "break-down" could result in a more mature sexuality contributing to fewer cases of sexual abuse and to the stabilisation of future couples on the long-term.

Scaling in cognitive performance reflects multiplicative multifractal cascade dynamics

PubMed Central

Stephen, Damian G.; Anastas, Jason R.; Dixon, James A.

2012-01-01

Self-organized criticality purports to build multi-scaled structures out of local interactions. Evidence of scaling in various domains of biology may be more generally understood to reflect multiplicative interactions weaving together many disparate scales. The self-similarity of power-law scaling entails homogeneity: fluctuations distribute themselves similarly across many spatial and temporal scales. However, this apparent homogeneity can be misleading, especially as it spans more scales. Reducing biological processes to one power-law relationship neglects rich cascade dynamics. We review recent research into multifractality in executive-function cognitive tasks and propose that scaling reflects not criticality but instead interactions across multiple scales and among fluctuations of multiple sizes.

Delirium is characterized by acute changes in mental status including inattention, disorganized thinking, and altered level of consciousness, and is highly prevalent in critically ill adults. Delirium has adverse consequences for both patients and the healthcare system; however, at this time, no effective treatment exists. The identification of effective prevention strategies is therefore a clinical and research imperative. An important limitation of previous reviews of delirium prevention is that interventions were considered in isolation and only direct evidence was used. Our systematic review will synthesize all existing data using network meta-analysis, a powerful statistical approach that enables synthesis of both direct and indirect evidence. We will search Ovid MEDLINE, CINAHL, Embase, PsycINFO, and Web of Science from 1980 to March 2016. We will search the PROSPERO registry for protocols and the Cochrane Library for published systematic reviews. We will examine reference lists of pertinent reviews and search grey literature and the International Clinical Trials Registry Platform for unpublished studies and ongoing trials. We will include randomized and quasi-randomized trials of critically ill adults evaluating any pharmacological, non-pharmacological, or multi-component intervention for delirium prevention, administered in or prior to (i.e., peri-operatively) transfer to the ICU. Two authors will independently screen search results and extract data from eligible studies. Risk of bias assessments will be completed on all included studies. To inform our network meta-analysis, we will first conduct conventional pair-wise meta-analyses for primary and secondary outcomes using random-effects models. We will generate our network meta-analysis using a Bayesian framework, assuming a common heterogeneity parameter across all comparisons, and accounting for correlations in multi-arm studies. We will perform analyses using WinBUGS software. This systematic review

Water Detection Based on Object Reflections

NASA Technical Reports Server (NTRS)

Rankin, Arturo L.; Matthies, Larry H.

2012-01-01

Water bodies are challenging terrain hazards for terrestrial unmanned ground vehicles (UGVs) for several reasons. Traversing through deep water bodies could cause costly damage to the electronics of UGVs. Additionally, a UGV that is either broken down due to water damage or becomes stuck in a water body during an autonomous operation will require rescue, potentially drawing critical resources away from the primary operation and increasing the operation cost. Thus, robust water detection is a critical perception requirement for UGV autonomous navigation. One of the properties useful for detecting still water bodies is that their surface acts as a horizontal mirror at high incidence angles. Still water bodies in wide-open areas can be detected by geometrically locating the exact pixels in the sky that are reflecting on candidate water pixels on the ground, predicting if ground pixels are water based on color similarity to the sky and local terrain features. But in cluttered areas where reflections of objects in the background dominate the appearance of the surface of still water bodies, detection based on sky reflections is of marginal value. Specifically, this software attempts to solve the problem of detecting still water bodies on cross-country terrain in cluttered areas at low cost.

Canine and feline preventative healthcare consultations can be more complex than other consultation types, but they are typically not allocated additional time in the United Kingdom (UK). Impacts of the perceived length of UK preventative healthcare consultations have not previously been described. The aim of this novel study was to provide the first qualitative description of owner and veterinary surgeon reflections on time during preventative healthcare consultations. Semi-structured telephone interviews were conducted with 14 veterinary surgeons and 15 owners about all aspects of canine and feline preventative healthcare consultations. These qualitative data were thematically analysed, and four key themes identified. This paper describes the theme relating to time and consultation length. Patient, owner, veterinary surgeon and practice variables were recalled to impact the actual, versus allocated, length of a preventative healthcare consultation. Preventative healthcare consultations involving young, old and multi-morbid animals and new veterinary surgeon-owner partnerships appear particularly susceptible to time pressures. Owners and veterinary surgeons recalled rushing and minimizing discussions to keep consultations within their allocated time. The impact of the pace, content and duration of a preventative healthcare consultation may be influential factors in consultation satisfaction. These interviews provide an important insight into the complex nature of preventative healthcare consultations and the behaviour of participants under different perceived time pressures. These data may be of interest and relevance to all stakeholders in dog and cat preventative healthcare.

Selenium is an essential trace element, but critically ill patients using total parenteral nutrition (PN) do not receive selenium because this mineral is not commonly offered. Threfore, the eval uation of plasma selenium levels is very important for treating or preventing this deficiency. Recent studies have shown that transthyretin may reflect the selenium intake and could be considered a biomarker. However, this issue is still little explored in the literature. This study aims to investigate the correlation of transthyretin with the plasma selenium of critically ill patients receiving PN. This was a prospective cohort study with 44 patients using PN without selenium. Blood samples were carried out in 3 stages: initial, 7th and 14th day of PN. In order to evaluate the clinical condition and the inflammatory process, albumin, C-reactive protein (CRP), transthyretin, creatinine and HDL cholesterol levels were observed. To assess the selenium status, plasma selenium and glutathione peroxidase (GPx) in whole blood were measured. Descriptive analyses were performed and the ANOVA, Mann-Whitney and Spearman's coefficient tests were conducted; we assumed a significance level of 5%. A positive correlation of selenium with the GPx levels (r = 0.46; p = 0.03) was identified. During two weeks, there was a positive correlation of transthyretin with plasma selenium (r = 0.71; p = 0.05) regardless of the CRP values. Transthyretin may have reflected plasma selenium, mainly because the correlation was verified after the acute phase.

Prevention of infections in an ART laboratory: a reflection on simplistic methods.

PubMed

Huyser, C

2014-01-01

Preventative measures combined with reactive remedial actions are generic management tools to optimize and protect an entity's core businesses. Differences between assisted reproduction technology (ART) laboratories in developing versus developed countries include restricted access to, or availability of resources, and the prevalence of pathological conditions that are endemic or common in non-industrialized regions. The aim of this paper is to discuss the prevention of infections in an ART laboratory in a low to middle-income country, with reference to simplistic risk reduction applications to avoid the introduction and transmission of pathogens. Diagnostic and procedural phases will be examined, i.e. (i) screening for microbes during patient evaluation, and (ii-iii) prevention of environmental and procedural contamination. Preventative action is enabled by knowledge of threats and the degree of risk involved. Awareness and understanding of the vulnerabilities in an ART system, wherein laboratory personnel operate, are invaluable assets when unforeseen equipment failure occurs or instant decisions have to be made to safeguard procedures. An inter-connective team approach to patient treatment, biosafety training and utilization of practical procedures such as semen decontamination, are fundamental tools in a laboratory's risk-reduction armoury to prevent and eliminate infectious elements.

Marin, Kelly A; Rotondo, Elena K

2017-01-01

The longitudinal study aims to expand what is known about the costs and benefits of narrating stressful experiences by exploring changes in rumination within the narrative process and comparing it to changes in self-reflection. Rumination (e.g., brooding, self-criticism, and negative emotions) and self-reflection were measured in stress narratives of 56 college students. There were several goals: (1) examine changes in narrative rumination and narrative self-reflection over 3 days of writing, (2) examine the relations among the changes in narrative rumination variables and narrative self-reflection and (3) examine how changes in narrative rumination and narrative self-reflection relate to multiple measures of psychological functioning. Overall, individuals increased self-reflection over the 3-day writing task. Individuals who increased ruminative brooding across the 3 days of writing showed lower ego identity development (short term and long term) and self-esteem (short term), while increased self-criticism was positively correlated with identity distress (short term). Implications of the different aspects of narrative rumination, specifically in the context of stressful experiences, are discussed.

Properties of seismic absorption induced reflections

NASA Astrophysics Data System (ADS)

Zhao, Haixia; Gao, Jinghuai; Peng, Jigen

2018-05-01

Seismic reflections at an interface are often regarded as the variation of the acoustic impedance (product of seismic velocity and density) in a medium. In fact, they can also be generated due to the difference in absorption of the seismic energy. In this paper, we investigate the properties of such reflections. Based on the diffusive-viscous wave equation and elastic diffusive-viscous wave equation, we investigate the dependency of the reflection coefficients on frequency, and their variations with incident angles. Numerical results at a boundary due to absorption contrasts are compared with those resulted from acoustic impedance variation. It is found that, the reflection coefficients resulted from absorption depend significantly on the frequency especially at lower frequencies, but vary very slowly at small incident angles. At the higher frequencies, the reflection coefficients of diffusive-viscous wave and elastic diffusive-viscous wave are close to those of acoustic and elastic cases, respectively. On the other hand, the reflections caused by acoustic impedance variation are independent of frequency but vary distinctly with incident angles before the critical angle. We also investigate the difference between the seismograms generated in the two different media. The numerical results show that the amplitudes of these reflected waves are attenuated and their phases are shifted. However, the reflections obtained by acoustic impedance contrast, show no significant amplitude attenuation and phase shift.

To develop a consensus on a set of key clinical outcomes for the evaluation of preventive interventions for preterm birth in asymptomatic pregnant women. A two-stage web-based Delphi survey and a face-to-face meeting of key stakeholders were used to develop a consensus on a set of critical and important outcomes. We approached five stakeholder groups (parents, midwives, obstetricians, neonatologists, and researchers) from middle- and high-income countries. Outcomes subjected to the Delphi survey were identified by systematic literature review and stakeholder input. Survey participants scored each outcome on a 9-point Likert scale anchored between 1 (limited importance) and 9 (critical importance). They had the opportunity to reflect on total and stakeholder subgroup feedback between survey stages. For consensus, defined a priori, outcomes required at least 70% of participants of each stakeholder group to score them as "critical" and less than 15% as "limited." A total of 228 participants from five stakeholder groups from three lower middle-income countries, seven upper middle-income countries, and 17 high-income countries were asked to score 31 outcomes. Of these participants, 195 completed the first survey and 174 the second. Consensus was reached on 13 core outcomes: four were related to pregnant women: maternal mortality, maternal infection or inflammation, prelabor rupture of membranes, and harm to mother from intervention. Nine were related to offspring: gestational age at birth, offspring mortality, birth weight, early neurodevelopmental morbidity, late neurodevelopmental morbidity, gastrointestinal morbidity, infection, respiratory morbidity, and harm to offspring from intervention. This core outcome set for studies that evaluate prevention of preterm birth developed with an international multidisciplinary perspective will ensure that data from trials that assess prevention of preterm birth can be compared and combined.

2018-02-01

Test the concurrent validity of three newly developed tools (student self-rating, preceptor rating, and reflective writing) that aim to measure critical thinking in midwifery practice. A descriptive matched cohort design was used. Australian research intensive university offering a three year Bachelor of Midwifery programme. Fifty-five undergraduate midwifery students. Students assessed their ability to apply critical thinking in midwifery practice using a 25-item tool and a 5-item subscale in Motivated Strategies for Learning Questionnaire. Clinical preceptors completed a 24-item tool assessing the students' application of critical thinking in practice. Reflective writing by students was assessed by midwifery academics using a 15-item tool. Internal reliability, and concurrent validity were assessed. Correlations, t-tests, multiple regression and confidence levels were calculated for the three scales and associations with student characteristics. The three scales achieved good internal reliability with a Cronbach's alpha coefficient between 0.93 and 0.97. Matched total scores for the three critical thinking scales were moderately correlated; student/preceptor (r=0.36, p<0.01); student/reflective writing (r=0.38, p<0.01); preceptor/reflective writing (r=0.30, p<0.05). All critical thinking mean scores were higher for students with a previous degree, but only significant for reflective writing (t (53)=-2.35, p=0.023). Preceptor ratings were predictive of GPA (beta=0.50, p<0.001, CI=0.10 to 0.30). Students' self-rating scores were predictive of year level (beta=0.32, p<0.05, CI=0.00 to 0.03). The student, preceptor, and reflective writing tools were found to be reliable and valid measures of critical thinking. The three tools can be used individually or in combination to provide students with various sources of feedback to improve their practice. The tools allow formative measurement of critical thinking over time. Further testing of the tools with larger, diverse

Exploring the attributes of critical thinking: a conceptual basis.

Forneris, Susan G

2004-01-01

Many teaching methods used in nursing education to enhance critical thinking focus on teaching students how to directly apply knowledge; a technically rational approach. While seemingly effective at enhancing students' critical thinking abilities in structured learning situations, these methods don't prepare students to operationalize critical thinking to manage the complexities that actually exist in practice. The work of contemporary educational theorists Paulo Freire, Donald Schon, Chris Argyris, Jack Mezirow, Stephen Brookfield, and Robert Tennyson all share similar perspectives on thinking in practice and the use of reflection to achieve a coherence of understanding. Their perspectives provide insight on how educators can shift from a means-end approach to operationalizing thinking in practice. The author identifies four attributes of critical thinking in practice evidenced in these views, followed by a discussion of specific educational strategies that reflect these attributes, and operationalize a critical thinking process in nursing practice to achieve a coherence of understanding.

Critically ill patients are at high risk of developing pressure ulcers (PU), with the sacrum and heels being highly susceptible to pressure injuries. The objective of our study was to evaluate the clinical effectiveness of a new multi-layer, self-adhesive soft silicone foam heel dressing to prevent PU development in trauma and critically ill patients in the intensive care unit (ICU). A cohort of critically ill patients were enrolled at the Royal Melbourne Hospital. Each patient had the multi-layer soft silicone foam dressing applied to each heel on admission to the emergency department. The dressings were retained with a tubular bandage for the duration of the patients' stay in the ICU. The skin under the dressings was examined daily and the dressings were replaced every three days. The comparator for our cohort study was the control group from the recently completed Border Trial. Of the 191 patients in the initial cohort, excluding deaths, loss to follow-up and transfers to another ward, 150 patients were included in the final analysis. There was no difference in key demographic or physiological variables between the cohorts, apart from a longer ICU length of stay for our current cohort. No PUs developed in any of our intervention cohort patients compared with 14 patients in the control cohort (n=152; p<0.001) who developed a total of 19 heel PUs. We conclude, based on our results, that the multi-layer soft silicone foam dressing under investigation was clinically effective in reducing ICU-acquired heel PUs. The findings also support previous research on the clinical effectiveness of multi-layer soft silicone foam dressings for PU prevention in the ICU.

Critical thinking is an essential skill in the nursing process. Although several studies have evaluated the critical thinking skills of nurses, there is limited information related to the indicators of critical thinking or evaluation of critical thinking in the context of the nursing process. This study investigated the potential indicators of critical thinking and the attributes of critical thinkers in clinical nursing practice. Knowledge of these indicators can aid the development of tools to assess nursing students' critical thinking skills. The study was conducted between September 2009 and August 2010. In phase 1, a literature review and four focus groups were conducted to identify the indicators of critical thinking in the context of nursing and the attributes of critical thinkers. In phase 2, 30 nursing professionals participated in a modified Delphi research survey to establish consensus and the appropriateness of each indicator and attribute identified in phase 1. We identified 37 indicators of critical thinking and 10 attributes of critical thinkers. The indicators were categorized into five subscales within the context of the nursing process toreflect nursing clinical practice: assessment, 16 indicators of ability to apply professional knowledge and skills to analyze and interpret patient problems; diagnosis, five indicators of ability to propose preliminary suppositions; planning, five indicators of ability to develop problem-solving strategies; implementation, five indicators of ability to implement planning; and evaluation, six indicators of ability to self-assess and reflect. The study operationalized critical thinking into a practical indicator suitable for nursing contexts in which critical thinking is required for clinical problem solving. Identified indicators and attributes can assist clinical instructors to evaluate student critical thought skills and development-related teaching strategies.

Searching and synthesising 'grey literature' and 'grey information' in public health: critical reflections on three case studies.

Grey literature includes a range of documents not controlled by commercial publishing organisations. This means that grey literature can be difficult to search and retrieve for evidence synthesis. Much knowledge and evidence in public health, and other fields, accumulates from innovation in practice. This knowledge may not even be of sufficient formality to meet the definition of grey literature. We term this knowledge 'grey information'. Grey information may be even harder to search for and retrieve than grey literature. On three previous occasions, we have attempted to systematically search for and synthesise public health grey literature and information-both to summarise the extent and nature of particular classes of interventions and to synthesise results of evaluations. Here, we briefly describe these three 'case studies' but focus on our post hoc critical reflections on searching for and synthesising grey literature and information garnered from our experiences of these case studies. We believe these reflections will be useful to future researchers working in this area. Issues discussed include search methods, searching efficiency, replicability of searches, data management, data extraction, assessing study 'quality', data synthesis, time and resources, and differentiating evidence synthesis from primary research. Information on applied public health research questions relating to the nature and range of public health interventions, as well as many evaluations of these interventions, may be predominantly, or only, held in grey literature and grey information. Evidence syntheses on these topics need, therefore, to embrace grey literature and information. Many typical systematic review methods for searching, appraising, managing, and synthesising the evidence base can be adapted for use with grey literature and information. Evidence synthesisers should carefully consider the opportunities and problems offered by including grey literature and information

1998-04-07

A critical illumination condenser system is disclosed, particularly adapted for use in extreme ultraviolet (EUV) projection lithography based on a ring field imaging system and a laser produced plasma source. The system uses three spherical mirrors and is capable of illuminating the extent of the mask plane by scanning either the primary mirror or the laser plasma source. The angles of radiation incident upon each mirror of the critical illumination condenser vary by less than eight (8) degrees. For example, the imaging system in which the critical illumination condenser is utilized has a 200 {micro}m source and requires a magnification of 26. The three spherical mirror system constitutes a two mirror inverse Cassegrain, or Schwarzschild configuration, with a 25% area obstruction (50% linear obstruction). The third mirror provides the final pupil and image relay. The mirrors include a multilayer reflective coating which is reflective over a narrow bandwidth. 6 figs.

Colorectal cancer (CRC) leads to significant morbidity/mortality worldwide. Defining critical research gaps (RG), their prioritisation and resolution, could improve patient outcomes. RG analysis was conducted by a multidisciplinary panel of patients, clinicians and researchers (n=71). Eight working groups (WG) were constituted: discovery science; risk; prevention; early diagnosis and screening; pathology; curative treatment; stage IV disease; and living with and beyond CRC. A series of discussions led to development of draft papers by each WG, which were evaluated by a 20-strong patient panel. A final list of RGs and research recommendations (RR) was endorsed by all participants. Fifteen critical RGs are summarised below: RG1 : Lack of realistic models that recapitulate tumour/tumour micro/macroenvironment; RG2 : Insufficient evidence on precise contributions of genetic/environmental/lifestyle factors to CRC risk; RG3 : Pressing need for prevention trials; RG4 : Lack of integration of different prevention approaches; RG5 : Lack of optimal strategies for CRC screening; RG6 : Lack of effective triage systems for invasive investigations; RG7 : Imprecise pathological assessment of CRC; RG8 : Lack of qualified personnel in genomics, data sciences and digital pathology; RG9 : Inadequate assessment/communication of risk, benefit and uncertainty of treatment choices; RG10 : Need for novel technologies/interventions to improve curative outcomes; RG11 : Lack of approaches that recognise molecular interplay between metastasising tumours and their microenvironment; RG12 : Lack of reliable biomarkers to guide stage IV treatment; RG13 : Need to increase understanding of health related quality of life (HRQOL) and promote residual symptom resolution; RG14 : Lack of coordination of CRC research/funding; RG15 : Lack of effective communication between relevant stakeholders.

Preventing ARDS

PubMed Central

Beitler, Jeremy R.; Schoenfeld, David A.

2014-01-01

Advances in critical care practice have led to a substantial decline in the incidence of ARDS over the past several years. Low tidal volume ventilation, timely resuscitation and antimicrobial administration, restrictive transfusion practices, and primary prevention of aspiration and nosocomial pneumonia have likely contributed to this reduction. Despite decades of research, there is no proven pharmacologic treatment of ARDS, and mortality from ARDS remains high. Consequently, recent initiatives have broadened the scope of lung injury research to include targeted prevention of ARDS. Prediction scores have been developed to identify patients at risk for ARDS, and clinical trials testing aspirin and inhaled budesonide/formoterol for ARDS prevention are ongoing. Future trials aimed at preventing ARDS face several key challenges. ARDS has not been validated as an end point for pivotal clinical trials, and caution is needed when testing toxic therapies that may prevent ARDS yet potentially increase mortality. PMID:25288000

This article reflects upon the research process that uses critical social science as its basis. Some of the common criticisms of critical social science research are rebutted by following the research trail taken by the authors when undertaking their own projects. The similarities and differences of critical social science and the interpretative methodologies are outlined in the selection of study area, the relationship of the researcher and participants, ethical issues, and data collection and analysis. The writers conclude that critical social science research reports that are correctly carried out should be firmly grounded in each of these stages, thereby a foundation for nursing and midwifery practice.

Effectiveness of heat and moisture exchangers in preventing ventilator-associated pneumonia in critically ill patients: a meta-analysis.

PubMed

Menegueti, Mayra Gonçalves; Auxiliadora-Martins, Maria; Nunes, Altacílio Aparecido

2014-01-01

Patients may acquire ventilator-associated pneumonia (VAP) by aspirating the condensate that originates in the ventilator circuit upon use of a conventional humidifier. The bacteria that colonize the patients themselves can proliferate in the condensate and then return to the airways and lungs when the patient aspirates this contaminated material. Therefore, the use of HME might contribute to preventing pneumonia and lowering the VAP incidence. The aim of this study was to evaluate how the use of HME impacts the probability of VAP occurrence in critically ill patients. On the basis of the acronym "PICO" (Patient, Intervention, Comparison, Outcome), the question that guided this review was "Do critically ill patients under invasive mechanical ventilation present lower VAP incidence when they use HME as compared with HH?". Two of the authors of this review searched the databases PUBMED/Medline, The Cochrane Library, and Latin-American and Caribbean Literature in Health Sciences, LILACS independently; they used the following keywords: "heat and moisture exchanger", AND "heated humidifier", AND "ventilator-associated pneumonia prevention". This review included papers in the English language published from January 1990 to December 2012. This review included ten studies. Comparison between the use of HME and HH did not reveal any differences in terms of VAP occurrence (OR = 0.998; 95% CI: 0.778-1.281). Together, the ten studies corresponded to a total sample of 1077 and 953 patients in the HME and HH groups, respectively; heterogeneity among the investigations was low (I(2) < 50%). Information about the outcome mortality was available in only eight of the ten studies. The use of HME and HH did not afford different results in terms of mortality (OR = 1.09; 95% CI: 0.864-1.376). The total sample size was 884 and 762 patients, respectively. Heterogeneity among the studies was low (I(2) = 0.0%). Current meta-analysis was not sufficient to definitely exclude an associate

Purpose: This study aims to investigate preventability criteria of adverse drug reactions (ADRs) involving non-steroidal anti-inflammatory drugs (NSAIDs) by analyzing individual case safety reports (ICSRs) sent through Campania region (Italy) spontaneous reporting system from July 2012 to October 2016. Methods: For all the ICSRs that reported NSAIDs as suspected drug, a trained multidisciplinary team of Campania Pharmacovigilance Regional Centre composed of clinical pharmacologists and pharmacists with pluriannual experience in Pharmacovigilance assessed preventability by using the P-method. Results: In all 19,039 ICSRs were sent to Campania Pharmacovigilance Regional Centre, of which 550 reported NSAIDs as suspected drug. In total, 94 cases (17.1%) out of 550 ICSRs were preventable. In the 94 preventable cases, 201 critical criteria were detected of which 182/201 (90.5%) related to healthcare professionals' practices, 0/201 (0.0%) to drug quality, and 19/201 (9.5%) to patient behavior. The most detected critical criteria were the necessary medication not given (52/182; 28.6%), labeled drug-drug interaction (36/182; 19.7%), incorrect drug administration duration (31/182; 16.9%), wrong indication (26/182; 14.2%), therapeutic duplication (18/182; 10.0%), and documented hypersensitivity to administered drug or drug class (10/182; 5.6%). In seventeen (18.1%) preventable cases, there were 19 critical criteria involving non-compliance (15/19 critical criteria; 78.9%) and self-medication with the non-over-the-counter drugs (4/19 critical criteria; 21.1%). In all, 17 out 94 (18.1%) preventable cases involved over-the-counter drugs. Conclusion: A call for action for Campania Pharmacovigilance Regional Centre is necessary in order to promote initiatives to increase the awareness of healthcare professionals and citizens on the risk associated with inappropriate use of NSAIDs.

Reflections on the Swiss Consensus Statement in the context of qualitative interviews with heterosexuals living with HIV.

Persson, A

2010-12-01

In 2008, the Swiss Federal AIDS Commission released a statement concluding that people with HIV who are on treatment and have an undetectable viral load are non-infectious and can safely practice unprotected sex with their HIV-negative partner under certain conditions. Contradicting over 25 years of HIV prevention messages, the so called Swiss Consensus Statement sparked a polarised international debate. One key concern is that the Statement will be misinterpreted to imply that everybody on treatment can have unprotected sex. Therefore, critics warn against any departure from the emphasis on condoms as the most effective prevention method. Given this concern, it is useful to reflect on what relevance the Swiss Statement may have for those concerned. This paper draws on qualitative interviews with HIV-positive heterosexuals and HIV-negative partners in Australia. Conducted both before and after the release of the Statement, these interviews revealed that sexual decision-making was not based solely on calculations of risk, but shaped by complex emotions and relationship priorities. The interviews also revealed that participants were sceptical towards the Statement's prevention message. These findings call into question the central concerns that drive this debate.

Dependency in Critically Ill Patients

PubMed Central

Yang, Rumei

2016-01-01

By necessity, critically ill patients admitted to intensive care units (ICUs) have a high level of dependency, which is linked to a variety of negative feelings, such as powerlessness. However, the term dependency is not well defined in the critically ill patients. The concept of “dependency” in critically ill patients was analyzed using a meta-synthesis approach. An inductive process described by Deborah Finfgeld-Connett was used to analyze the data. Overarching themes emerged that reflected critically ill patients’ experience and meaning of being in dependency were (a) antecedents: dependency in critically ill patients was a powerless and vulnerable state, triggered by a life-threatening crisis; (b) attributes: the characteristic of losing “self” was featured by dehumanization and disembodiment, which can be alleviated by a “self”-restoring process; and (c) outcomes: living with dependency and coping with dependency. The conceptual model explicated here may provide a framework for understanding dependency in critically ill patients. PMID:28462328

Objective To identify individual and social factors associated with pharmacy students' level of reflection in an advanced pharmacy practice experience (APPE). Methods A postal questionnaire, including a reflective assignment, was sent to all pharmacy interns (n=262) at Uppsala University, Sweden, for 4 semesters in 2005-2007. Results In a univariate analysis, 7 factors were found to be associated with students' level of reflection. After controlling for covariates, 3 social factors were found to be independently associated with reflection: having a formal preceptor (OR=5.3), being at a small pharmacy (OR=19.8), and students' perception of the importance of discussing critical thinking with the preceptor (OR=1.2). No correlation could be observed between level of reflection and critical thinking, nor learning style. Conclusion Social components seem to be of higher importance than individual components in students' reflective levels after pharmacy internship experience. Trained preceptors are important to foster reflection skills. PMID:19885076

Metasurface-based anti-reflection coatings at optical frequencies

Monti, Alessio; Alù, Andrea; Toscano, Alessandro; Bilotti, Filiberto

2018-05-01

In this manuscript, we propose a metasurface approach for the reduction of electromagnetic reflection from an arbitrary air‑dielectric interface. The proposed technique exploits the exotic optical response of plasmonic nanoparticles to achieve complete cancellation of the field reflected by a dielectric substrate by means of destructive interference. Differently from other, earlier anti-reflection approaches based on nanoparticles, our design scheme is supported by a simple transmission-line formulation that allows a closed-form characterization of the anti-reflection performance of a nanoparticle array. Furthermore, since the working principle of the proposed devices relies on an average effect that does not critically depend on the array geometry, our approach enables low-cost production and easy scalability to large sizes. Our theoretical considerations are supported by full-wave simulations confirming the effectiveness of this design principle.

2011-10-01

The purposes of the present study were two-fold: first, to evaluate whether reflection journal writing was effective in promoting self-reflection and learning, and whether students become better at self-reflection if they engage continuously in reflection journal writing. To that end, the reflection journals of 690 first-year applied science students at a local polytechnic were studied by means of an automated coding procedures using software. Data was collected twice, once at the beginning and again towards the end of an academic year. Outcomes of the textual content analyses revealed that students reflected on both the process and contents of their learning: critical review of past learning experiences, learning strategies and summaries of what was learned. Correlational analyses showed weak to moderate inter-relationships between the textual categories and their classroom and knowledge acquisition test grades. Taken together, the findings suggest that self-reflection on both how and what students have learned does lead to improvements in academic performance, although to a limited extent.

J. Willard Gibbs, the younger was the first American theorist. He was one of the inventors of statistical physics. His introduction and development of the concepts of phase space, phase transitions, and thermodynamic surfaces was remarkably correct and elegant. These three concepts form the basis of different but related areas of physics. The connection among these areas has been a subject of deep reflection from Gibbs' time to our own. I shall talk about these connections by using concepts suggested by the work of Michael Berry and explicitly put forward by the philosopher Robert Batterman. This viewpoint relates theory-connection to the applied mathematics concepts of asymptotic analysis and singular perturbations. J. Willard Gibbs, the younger, had all his achievements concentrated in science. His father, also J. Willard Gibbs, also a Professor at Yale, had one great achievement that remains unmatched in our day. I shall describe it.

(De)colonizing culture in community psychology: reflections from critical social science.

PubMed

Reyes Cruz, Mariolga; Sonn, Christopher C

2011-03-01

Since its inception, community psychology has been interested in cultural matters relating to issues of diversity and marginalization. However, the field has tended to understand culture as static social markers or as the background for understanding group differences. In this article the authors contend that culture is inseparable from who we are and what we do as social beings. Moreover, culture is continually shaped by socio-historical and political processes intertwined within the globalized history of power. The authors propose a decolonizing standpoint grounded in critical social science to disrupt understandings of cultural matters that marginalize others. This standpoint would move the field toward deeper critical thinking, reflexivity and emancipatory action. The authors present their work to illustrate how they integrate a decolonizing standpoint to community psychology research and teaching. They conclude that community psychology must aim towards intercultural work engaging its political nature from a place of ontological/epistemological/methodological parity.

Inducible HSP70 Is Critical in Preventing the Aggregation and Enhancing the Processing of PMP22

PubMed Central

Chittoor-Vinod, Vinita G.; Lee, Sooyeon; Judge, Sarah M.

2015-01-01

Chaperones, also called heat shock proteins (HSPs), transiently interact with proteins to aid their folding, trafficking, and degradation, thereby directly influencing the transport of newly synthesized molecules. Induction of chaperones provides a potential therapeutic approach for protein misfolding disorders, such as peripheral myelin protein 22 (PMP22)-associated peripheral neuropathies. Cytosolic aggregates of PMP22, linked with a demyelinating Schwann cell phenotype, result in suppression of proteasome activity and activation of proteostatic mechanisms, including the heat shock pathway. Although the beneficial effects of chaperones in preventing the aggregation and improving the trafficking of PMP22 have been repeatedly observed, the requirement for HSP70 in events remains elusive. In this study, we show that activation of the chaperone pathway in fibroblasts from PMP22 duplication-associated Charcot–Marie–Tooth disease type 1A patient with an FDA-approved small molecule increases HSP70 expression and attenuates proteasome dysfunction. Using cells from an HSP70.1/3−/− (inducible HSP70) mouse model, we demonstrate that under proteotoxic stress, this chaperone is critical in preventing the aggregation of PMP22, and this effect is aided by macroautophagy. When examined at steady-state, HSP70 appears to play a minor role in the trafficking of wild-type-PMP22, while it is crucial for preventing the buildup of the aggregation-prone Trembler-J-PMP22. HSP70 aids the processing of Trembler-J-PMP22 through the Golgi and its delivery to lysosomes via Rab7-positive vesicles. Together, these results demonstrate a key role for inducible HSP70 in aiding the processing and hindering the accumulation of misfolded PMP22, which in turn alleviates proteotoxicity within the cells.

Canine and feline preventative healthcare consultations can be more complex than other consultation types, but they are typically not allocated additional time in the United Kingdom (UK). Impacts of the perceived length of UK preventative healthcare consultations have not previously been described. The aim of this novel study was to provide the first qualitative description of owner and veterinary surgeon reflections on time during preventative healthcare consultations. Semi-structured telephone interviews were conducted with 14 veterinary surgeons and 15 owners about all aspects of canine and feline preventative healthcare consultations. These qualitative data were thematically analysed, and four key themes identified. This paper describes the theme relating to time and consultation length. Patient, owner, veterinary surgeon and practice variables were recalled to impact the actual, versus allocated, length of a preventative healthcare consultation. Preventative healthcare consultations involving young, old and multi-morbid animals and new veterinary surgeon-owner partnerships appear particularly susceptible to time pressures. Owners and veterinary surgeons recalled rushing and minimizing discussions to keep consultations within their allocated time. The impact of the pace, content and duration of a preventative healthcare consultation may be influential factors in consultation satisfaction. These interviews provide an important insight into the complex nature of preventative healthcare consultations and the behaviour of participants under different perceived time pressures. These data may be of interest and relevance to all stakeholders in dog and cat preventative healthcare. PMID:29419766

Looking Inward: Philosophical and Methodological Perspectives on Phenomenological Self-Reflection.

Pool, Natalie M

2018-07-01

Engaging in early and ongoing self-reflection during interpretive phenomenological research is critical for ensuring trustworthiness or rigor. However, the lack of guidelines and clarity about the role of self-reflection in this methodology creates both theoretical and procedural confusion. The purpose of this article is to describe key philosophical underpinnings, characteristics, and hallmarks of the process of self-reflection in interpretive phenomenological investigation and to provide a list of guidelines that facilitate this process. Excerpts from an interpretive phenomenological study are used to illustrate characteristics of quality self-reflection. The guidelines are intended to be particularly beneficial for novice researchers who may find self-reflective writing to be daunting and unclear. Facilitating use of self-reflection may strengthen both the interpretive phenomenological body of work as well as that of all qualitative research.

Chen, Yu-Chih

2009-04-01

Ventilator-associated pneumonia (VAP) is a common cause of morbidity in critically ill patients. Appropriate enteral feeding is the most important factor associated with the prevention of VAP. However, the standardization of enteral feeding methods needs clarification. The purpose of this systematic review was to synthesize the factors associated with enteral feeding in order to prevent VAP and to describe the characteristics of these factors. A comprehensive search was undertaken involving all major databases from their inception to September 2008 using medical subject heading terms associated with enteral feeding in relation to VAP. The overall reference list of identified studies was audited, and eligible studies included randomized controlled trials, controlled before-and-after (pre-post) studies and meta-analyses. To generate the characteristics of the factors associated with VAP, the reported components of these trials were pinpointed and categorized. A total of 14 papers were found that had investigated the factors linking enteral feeding and VAP. For these, 11 were randomized controlled trials, 1 was a meta-analysis and 2 were case-controlled analyses. Twelve of these 14 studies were conducted at a single institute and 2 were conducted at multiple institutes. The sample sizes varied from 10 to 2,528 subjects. Three major issues were identified based on the purpose of study interventions, and these were the effects of feeding method (continuous vs. intermittent), feeding site on aspiration (gastric vs. small bowel), and the timing of enteral feeding (early vs. late). The evidence suggests that a correct choice of enteral feeding method can effectively reduce complications due to aspiration. Furthermore, intermittent enteral feeding and with a small residual volume feed can reduce gastroesophageal reflux, and increased total intake volume and early feeding can reduce ICU mortality. Nonetheless, the effects of these choices on preventing VAP still need further

An educational video to promote multi-factorial approaches for fall and injury prevention in long-term care facilities

PubMed Central

2014-01-01

Background Older adults living in long term care (LTC) settings are vulnerable to fall-related injuries. There is a need to develop and implement evidence-based approaches to address fall injury prevention in LTC. Knowledge translation (KT) interventions to support the uptake of evidence-based approaches to fall injury prevention in LTC need to be responsive to the learning needs of LTC staff and use mediums, such as videos, that are accessible and easy-to-use. This article describes the development of two unique educational videos to promote fall injury prevention in long-term care (LTC) settings. These videos are unique from other fall prevention videos in that they include video footage of real life falls captured in the LTC setting. Methods Two educational videos were developed (2012–2013) to support the uptake of findings from a study exploring the causes of falls based on video footage captured in LTC facilities. The videos were developed by: (1) conducting learning needs assessment in LTC settings via six focus groups (2) liaising with LTC settings to identify learning priorities through unstructured conversations; and (3) aligning the content with principles of adult learning theory. Results The videos included footage of falls, interviews with older adults and fall injury prevention experts. The videos present evidence-based fall injury prevention recommendations aligned to the needs of LTC staff and: (1) highlight recommendations deemed by LTC staff as most urgent (learner-centered learning); (2) highlight negative impacts of falls on older adults (encourage meaning-making); and, (3) prompt LTC staff to reflect on fall injury prevention practices (encourage critical reflection). Conclusions Educational videos are an important tool available to researchers seeking to translate evidence-based recommendations into LTC settings. Additional research is needed to determine their impact on practice. PMID:24884899

Medical ethics as a scholarly discipline and a system of moral principles that apply values and judgments to the practice of medicine encompasses its practical application in clinical settings as well as work on its history, philosophy, theology, anthropology and sociology. As such there are a number of values in medical ethics such as autonomy, non-maleficence, confidentiality, dignity, honesty, justice and beneficence, among others. These values act as guidelines for professionals in the medical fraternity and are therefore used to judge different cases in the fraternity. For purposes of this work, this paper examines the principle of beneficence in biomedicine. Using both hypothetical cases and others in real life situations, the paper reflects on the implications of beneficence in biomedicine. It argues that the principle of beneficence is a prima facie obligation that should "always be acted upon unless it conflicts on a particular occasion with an equal or stronger principle".

As in other countries worldwide, adults with severe mental illness (SMI) in Brazil are disproportionately infected with HIV relative to the general population. Brazilian psychiatric facilities lack tested HIV prevention interventions. To adapt existing interventions, developed only in the US, we conducted targeted ethnography with adults with SMI and staff from two psychiatric institutions in Brazil. We sought to characterize individual, institutional, and interpersonal factors that may affect HIV risk behavior in this population. We conducted 350 hours of ethnographic field observations in two mental health service settings in Rio de Janeiro, and 9 focus groups (n=72) and 16 key-informant interviews with patients and staff in these settings. Data comprised field notes and audiotapes of all exchanges, which were transcribed, coded, and systematically analyzed. The ethnography identified and/or characterized the institutional culture: (1) patients' risk behaviors; (2) the institutional setting; (3) intervention content; and (4) intervention format and delivery strategies. Targeted ethnography also illuminated broader contextual issues for development and implementation of HIV prevention interventions for adults with SMI in Brazil, including an institutional culture that did not systematically address patients' sexual behavior, sexual health, or HIV sexual risk, yet strongly impacted the structure of patients' sexual networks. Further, ethnography identified the Brazilian concept of "social responsibility" as important to prevention work with psychiatric patients. Targeted ethnography with adults with SMI and institutional staff provided information critical to the adaptation of tested US HIV prevention interventions for Brazilians with SMI.

Essential elements for community engagement in evidence-based youth violence prevention.

Miao, Tai-An; Umemoto, Karen; Gonda, Deanna; Hishinuma, Earl S

2011-09-01

In the field of youth violence prevention, there has been increasing emphasis on "evidence based" programs and principles shown through scientific research as reaching their intended outcomes. Community mobilization and engagement play a critical role in many evidence-based programs and strategies, as it takes a concerted effort among a wide range of people within a community to alter behavior and maintain behavioral change. How do concerned individuals and groups within a community engage others within and outside of that community to effectively plan, develop and implement appropriate EB programs as well as evaluate the outcomes and impacts of locally developed programs yet to be proven? The authors discuss five elements essential for community engagement in evidence-based youth violence prevention based on their work in a university-community partnership through the Asian/Pacific Islander Youth Violence Prevention Center (API Center), a National Academic Center for Excellence on Youth Violence Prevention Center supported by the Centers for Disease Control and Prevention. They include: (a) aligning EBPs with a community's shared vision and values; (b) establishing an inclusive environment for the planning, implementation and evaluation of EBPs; (c) nurturing collaboration for increased effectiveness and efficacy of EBPs; (d) building adequate leadership and community capacity to develop and sustain EBPs; and (e) building a learning community for evaluation and self-reflection. The authors propose placing greater emphasis on "evaluative thinking" and organizational capacity for evaluation as we pursue evidence-based practices for youth violence prevention. This is especially important for ethnic groups for which an evidence base is not well established.

Little is known about the cost-benefit of soft silicone foam dressings in pressure ulcer (PU) prevention among critically ill patients in the emergency department (ED) and intensive care unit (ICU). A randomised controlled trial to assess the efficacy of soft silicone foam dressings in preventing sacral and heel PUs was undertaken among 440 critically ill patients in an acute care hospital. Participants were randomly allocated either to an intervention group with prophylactic dressings applied to the sacrum and heels in the ED and changed every 3 days in the ICU or to a control group with standard PU prevention care provided during their ED and ICU stay. The results showed a significant reduction of PU incidence rates in the intervention group (P = 0·001). The intervention cost was estimated to be AU$36·61 per person based on an intention-to-treat analysis, but this was offset by lower downstream costs associated with PU treatment (AU$1103·52). Therefore, the average net cost of the intervention was lower than that of the control (AU$70·82 versus AU$144·56). We conclude that the use of soft silicone multilayered foam dressings to prevent sacral and heel PUs among critically ill patients results in cost savings in the acute care hospital. © 2013 The Authors.

This study was completed within the framework of two research projects dealing with the conservation of contemporary artworks. The first is the Seventh Framework Project (FP7) of the European Union, Preservation of Plastic ARTefacts in Museum Collections (POPART), spanning years 2008-2012, and the second is the Italian project funded by the Tuscan Region, Preventive Conservation of Contemporary Art (Conservazione Preventiva dell'Arte Contemporanea (COPAC)), spanning 2011-2013. Both of these programs pointed out the great importance of having noninvasive and portable analytical techniques that can be used to investigate and characterize modern and contemporary artworks, especially those consisting of synthetic polymers. Indeed, despite the extensive presence of plastics in museum collections, there is still a lack of analytical tools for identifying, characterizing, and setting up adequate conservation strategies for these materials. In this work, the potentials of in situ and noninvasive Fourier transform infrared (FT-IR) spectroscopy, implemented by means of portable devices that operate in reflection mode, are investigated with a view to applying the results in large-scale surveys of plastic objects in museums. To this end, an essential prerequisite are the reliability of spectral data acquired in situ and the availability of spectral databases acquired from reference materials. A collection of polymeric samples, which are available commercially as ResinKit, was analyzed to create a reference spectral archive. All the spectra were recorded using three FT-IR configurations: transmission (trans), attenuated total reflection (ATR), and total reflection (TR). A comparative evaluation of the data acquired using the three instrumental configurations is presented, together with an evaluation of the similarity percentages and a discussion of the critical cases.

Remote sensing is widely used assess the destruction from natural disasters and to plan relief and recovery operations. How to automatically extract useful features and segment interesting objects from digital images, including remote sensing imagery, becomes a critical task for image understanding. Unfortunately, current research on automated feature extraction is ignorant of contextual information. As a result, the fidelity of populating attributes corresponding to interesting features and objects cannot be satisfied. In this paper, we present an exploration on meaningful object extraction integrating reflecting surfaces. Detection of specular reflecting surfaces can be useful in target identification and then can be applied to environmental monitoring, disaster prediction and analysis, military, and counter-terrorism. Our method is based on a statistical model to capture the statistical properties of specular reflecting surfaces. And then the reflecting surfaces are detected through cluster analysis.

Graduate medical education programs employ reflection to advance a range of outcomes for physicians in training. However, the most effective applications of this tool have not been fully explored. A systematic review of the literature examined interventions reporting the use of reflection in graduate medical education. The authors searched Medline/PubMed, Embase, Cochrane CENTRAL, and ERIC for studies of reflection as a teaching tool to develop medical trainees' capacities. Key words and subject headings included reflection , narrative , residents/GME , and education / teaching / learning . No language or date limits were applied. The search yielded 1308 citations between inception for each database and June 15, 2015. A total of 16 studies, encompassing 477 residents and fellows, met eligibility criteria. Study quality was assessed using the Critical Appraisal Skills Programme Qualitative Checklist. The authors conducted a thematic analysis of the 16 articles. Outcomes studied encompassed the impact of reflection on empathy, comfort with learning in complex situations, and engagement in the learning process. Reflection increased learning of complex subjects and deepened professional values. It appears to be an effective tool for improving attitudes and comfort when exploring difficult material. Limitations include that most studies had small samples, used volunteers, and did not measure behavioral outcomes. Critical reflection is a tool that can amplify learning in residents and fellows. Added research is needed to understand how reflection can influence growth in professional capacities and patient-level outcomes in ways that can be measured.

Non-ARC solution to metal reflective notching: its evaluation and selection

NASA Astrophysics Data System (ADS)

Buffat, Stephen J.

1997-07-01

Patterning photoresists on reflective topography such as aluminum is one of the more difficult problems in device manufacturing. Interference effects caused by reflected light from the substrate/photoresist interface and surface topography result in coupling of additional energy into the film. This leads to linewidth variation known as reflective notching which severely impacts process latitude and increases critical dimension variation. For many years, suppliers approached the problem by adding dyes that absorb in the actinic region to create a larger non-bleachable absorption. In recent years, strongly absorbing intermediate layers or ARC's, both organic and inorganic, have seen widespread implementation to control reflective notching. However, if a fab is not equipped to accommodate the required ARC process, the processing can be very time consuming, cumbersome and costly. This study was undertaken to determine if a non-ARC, i-line photoresist process could be developed to reduce or eliminate aluminum reflective notching and accompanying critical dimension variation. This study was designed to screen, identify, and characterize various resist chemistries. Based on the screening characterization, a final, cost effective resist chemistry without ARC was selected, fully characterized and transferred into production. The selected material is currently being used in a high volume 0.60 micrometers CMOS, 200 mm wafer manufacturing process.

Multi-phase layered model traveltimes tomography inversions can be realised in several ways depending on the inversion path. Inverting the shape of the boundaries based on reflection data and the velocity field based on refractions could be done jointly or sequentially. We analyse an optimal inversion path based on the uncertainty analysis of the final models. Additionally, we propose to use post critical wide-angle reflections in tomographic inversions for more reliable results especially in the deeper parts of each layer. We focus on the effects of using hard to pick post critical reflections on the final model uncertainty. Our study is performed using data collected during standard vibroseis and explosive sources seismic reflection experiment focused on shale gas reservoir characterisation realised by Polish Oil and Gas Company. Our data were gathered by a standalone single component stations deployed along the whole length of the 20 km long profile, resulting in significantly longer offsets. Our piggy back recordings resulted in good quality wide angle refraction and reflection recordings clearly observable up to the offsets of 12 km.

Cultural differences in dealing with critical incidents.

PubMed

Leonhardt, Jörg; Vogt, Joachim

2009-01-01

This article discusses the cultural aspects of High Reliability Organizations (HROs), such as air navigation services. HROs must maintain a highly professional safety culture and constantly be prepared to handle crises. The article begins with a general discussion of the concept of organizational culture. The special characteristics of HROs and their safety culture is then described. Finally the article illustrates how Critical Incident Stress Management (CISM) is becoming an ingrained feature of the organizational culture in air traffic control systems. Critical Incident Stress Management is a prevention program that can successfully guard against the negative effects of critical incidents. The CISM program of DFS (Deutsche Flugsicherung) was recently evaluated by the University of Copenhagen. This evaluation not only confirmed the successful prevention of negative effects at the operation's employee level (especially air traffic controllers), but also showed a sustained improvement of its safety culture and its overall organizational performance. The special aspects of cross-cultural crisis intervention and the challenges it faces, as well as the importance of prevention programs, such as CISM, are illustrated using the examples of two aircraft accidents: the crash landing of a calibration aircraft and the Lake Constance air disaster.

The Canadian "Think Again" social marketing HIV/AIDS prevention campaign, adapted from an American effort, encourages gay men to rethink their assumptions about their partners' HIV statuses and the risks of unsafe sex with them. To improve future efforts, existing HIV/AIDS prevention initiatives require critical reflection. While a formal evaluation of this campaign has been carried out elsewhere, here we use the campaign as a social marketing case study to illustrate its strengths and weaknesses, as a learning tool for other campaigns. After describing the campaign and its key results, we assess how it utilized central tenets of the social marketing process, such as formative research and the marketing mix. We then speak to the importance of theoretical influence in campaign design and the need to account for social-contextual factors in safer sex decision making. We conclude with a summary of the lessons learned from the assessment of this campaign.

To summarize the current literature on racial and gender disparities in critical care and the mechanisms underlying these disparities in the course of acute critical illness. MEDLINE search on the published literature addressing racial, ethnic, or gender disparities in acute critical illness, such as sepsis, acute lung injury, pneumonia, venous thromboembolism, and cardiac arrest. Clinical studies that evaluated general critically ill patient populations in the United States as well as specific critical care conditions were reviewed with a focus on studies evaluating factors and contributors to health disparities. Study findings are presented according to their association with the prevalence, clinical presentation, management, and outcomes in acute critical illness. This review presents potential contributors for racial and gender disparities related to genetic susceptibility, comorbidities, preventive health services, socioeconomic factors, cultural differences, and access to care. The data are organized along the course of acute critical illness. The literature to date shows that disparities in critical care are most likely multifactorial involving individual, community, and hospital-level factors at several points in the continuum of acute critical illness. The data presented identify potential targets as interventions to reduce disparities in critical care and future avenues for research.

The environment is an underutilized pathway to breast cancer prevention. Current research approaches and funding streams related to breast cancer and the environment are unequal to the task at hand. We undertook the California Breast Cancer Prevention Initiatives, a four-year comprehensive effort to set a research agenda related to breast cancer, the environment, disparities and prevention. We identified 20 topics for Concept Proposals reflecting a life-course approach and the complex etiology of breast cancer; considering the environment as chemical, physical and socially constructed exposures that are experienced concurrently: at home, in the community and at work; and addressing how we should be modifying the world around us to promote a less carcinogenic environment. Redirecting breast cancer research toward prevention-oriented discovery could significantly reduce the incidence and associated disparities of the disease among future generations.

Reflective coating for near-infrared immersion gratings

NASA Astrophysics Data System (ADS)

Kuzmenko, Paul J.; Ikeda, Yuji; Kobayashi, Naoto; Mirkarimi, Paul B.; Alameda, Jennifer B.

2012-09-01

Achieving high reflectivity from an immersed grating facet can be challenging in the near infrared. The reflectivity of metallic coatings in common use, such as Al and Cr/Au, decrease with decreasing wavelength in the near IR. A layer of copper on ZnSe or ZnS should have a high, immersed reflectivity based on tabulated values of refractive index, but in fact performs poorly. We attribute this to a chemical reaction between the copper and the selenium or sulfur. A non-reactive intermediate layer can prevent this problem. Since reflectivity at an interface increases with increasing difference in refractive index, it is beneficial to choose an intermediate layer of low index. A further improvement is gained by adjusting the layer thickness so that reflections from the two interfaces of the intermediate layer add constructively. We sputtered 130 nm of SiO2 onto ZnSe and ZnS substrates followed by 200 nm of Cu. The copper was then coated with 5 nm of SiC as a protective capping layer. Immersed reflectivity measured shortly after coating exceeded 95% between 1500 and 1100 nm and exceeded 90% down to 850 nm. A repeat measurement after long term exposure to high humidity conditions showed no changes.

Very High Reflectivity Supermirrors And Their Applications

Mezei, F.

1989-01-01

Very high reflectivity (some 95 % or better) supermirrors, with cut-off angles up to 2 times the critical angle of Ni coated simple total reflection neutron mirrors, can be produced using well established conventional deposition techniques. This performance makes applications involving multiple reflections and transmission geometries feasible, which in turn allow us to use more sophisticated neutron optical systems in order to optimize performance and minimize the amount a scarce supermirrors required. A key feature of several of these novel systems is the distribution of tasks between the several optical components achieving the desired performance by multiple action. The design and characteristics of a series of novel applications, such as polarizing cavities, collimators and guides, non-polarizing guides, beam compressors, deflectors and splitters (most of them tested or being implemented) are the main subjects of the present paper.

Based on the WFD, the European Commission and will offer support to Member States on how to develop waste prevention programmes through guidelines and information sharing on best practices. Monitoring and evaluating waste prevention activities are critical, as they constitute the main tools to enable policy makers, at the national and local level, to build their strategic plans and ensure that waste prevention initiatives are effective and deliver behaviour change. However, how one can measure something that is not there, remains an important and unresolved research question. The paper reviews and attempts to evaluate the methods that are being used for measuring waste prevention and the impact of relevant implemented activities at the household level, as the available data is still limited.

Air bubbles induce a critical continuous stress to prevent marine biofouling accumulation

NASA Astrophysics Data System (ADS)

Belden, Jesse; Menesses, Mark; Dickenson, Natasha; Bird, James

2017-11-01

Significant shear stresses are needed to remove established hard fouling organisms from a ship hull. Given that there is a link between the amount of time that fouling accumulates and the stress required to remove it, it is not surprising that more frequent grooming requires less shear stress. One approach to mitigate marine biofouling is to continuously introduce a curtain of air bubbles under a submerged surface; it is believed that this aeration exploits the small stresses induced by rising bubbles to continuously prevent accumulation. Although curtains of rising bubbles have successfully prevented biofouling accumulation, it is unclear if a single stream of bubbles could maintain a clean surface. In this talk, we show that single bubble stream aeration can prevent biofouling accumulation in regions for which the average wall stress exceeds approximately 0.01 Pa. This value is arrived at by comparing observations of biofouling growth and prevention from field studies with laboratory measurements that probe the associated flow fields. We also relate the spatial and temporal characteristics of the flow to the size and frequency of the rising bubbles, which informs the basic operating conditions required for aeration to continuously prevent biofouling accumulation.

2017-11-01

To explore when and in what form pediatric faculty and residents practice reflection. From February to June 2015, the authors conducted focus groups of pediatric faculty and residents at the University of California, Davis; Stanford University; and the University of California, San Francisco, until thematic saturation occurred. Transcripts were analyzed based on Mezirow's and Schon's models of reflection, using the constant comparative method associated with grounded theory. Two investigators independently coded transcripts and reconciled codes to develop themes. All investigators reviewed the codes and developed a final list of themes through consensus. Through iterative discussions, investigators developed a conceptual model of reflection in the clinical setting. Seventeen faculty and 20 residents from three institutions participated in six focus groups. Five themes emerged: triggers of reflection, intrinsic factors, extrinsic factors, timing, and outcome of reflection. Various triggers led to reflection; whether a specific trigger led to reflection depended on intrinsic and extrinsic factors. When reflection occurred, it happened in action or on action. Under optimal conditions, this reflection was goal and action directed and became critical reflection. In other instances, this process resulted in unproductive rumination or acted as an emotional release or supportive therapy. Participants reflected in clinical settings, but did not always explicitly identify it as reflection or reflect in growth-promoting ways. Strategies to enhance critical reflection include developing knowledge and skills in reflection, providing performance data to inform reflection, creating time and space for safe reflection, and providing mentorship to guide the process.

Mastitis prevention and control practices and mastitis treatment strategies associated with the consumption of (critically important) antimicrobials on dairy herds in Flanders, Belgium.

PubMed

Stevens, M; Piepers, S; De Vliegher, S

2016-04-01

The main objectives of this study were to evaluate to what extent variations in herd-level antimicrobial consumption (AMC) can be explained by differences in management practices that are consistently effective in the prevention of (sub)clinical mastitis, on the one hand, and by differences in mastitis treatment strategies, on the other hand. Antimicrobial consumption data were obtained during 2012 and 2013 by "garbage can audits" and expressed as antimicrobial treatment incidences (ATI) for all compounds combined (total ATI) and for the critically important antimicrobials for human health separately. Data on mastitis prevention and control practices were obtained via face-to-face interviews performed during herd visits in March 2013. Some management practices and treatment strategies related to udder health were associated with the total AMC. However, the results demonstrated that implementing effective udder health management practices does not necessarily imply a low AMC and vice versa. Herds participating in a veterinary herd health management program and herds selectively drying off cows used fewer antimicrobials compared with herds not participating in such a program or applying blanket dry-cow therapy. Moreover, herds treating (some) (sub)clinical mastitis cases with intramammary homeopathic substances consumed fewer antimicrobials than herds not applying such homeopathic treatments. Besides these factors, no other direct association was found between effective udder health management practices on the one hand and AMC on the other hand. Also, the use of critically important antimicrobials was only associated with the way in which subclinical mastitis cases were treated. The latter indicates that the AMC of critically important antimicrobials is potentially driven by factors other than those included in this study such as those related to the "mindset" of the veterinarians and their farmers. Future research should therefore aim to unravel the reasoning of

Minimising back reflections from the common path objective in a fundus camera

NASA Astrophysics Data System (ADS)

Swat, A.

2016-11-01

Eliminating back reflections is critical in the design of a fundus camera with internal illuminating system. As there is very little light reflected from the retina, even excellent antireflective coatings are not sufficient suppression of ghost reflections, therefore the number of surfaces in the common optics in illuminating and imaging paths shall be minimised. Typically a single aspheric objective is used. In the paper an alternative approach, an objective with all spherical surfaces, is presented. As more surfaces are required, more sophisticated method is needed to get rid of back reflections. Typically back reflections analysis, comprise treating subsequent objective surfaces as mirrors, and reflections from the objective surfaces are traced back through the imaging path. This approach can be applied in both sequential and nonsequential ray tracing. It is good enough for system check but not very suitable for early optimisation process in the optical system design phase. There are also available standard ghost control merit function operands in the sequential ray-trace, for example in Zemax system, but these don't allow back ray-trace in an alternative optical path, illumination vs. imaging. What is proposed in the paper, is a complete method to incorporate ghost reflected energy into the raytracing system merit function for sequential mode which is more efficient in optimisation process. Although developed for the purpose of specific case of fundus camera, the method might be utilised in a wider range of applications where ghost control is critical.

Diversity in the physician workforce is essential to providing culturally effective care. In critical care, despite the high stakes and frequency with which cultural concerns arise, it is unknown whether physician diversity reflects that of critically ill patients. We sought to characterize demographic trends in critical care fellows, who represent the emerging intensivist workforce. We used published data to create logistic regression models comparing annual trends in the representation of women and racial/ethnic groups across critical care fellowship types. United States Accreditation Council on Graduate Medical Education-approved residency and fellowship training programs. Residents and fellows employed by Accreditation Council on Graduate Medical Education-accredited training programs from 2004 to 2014. None. From 2004 to 2014, the number of critical care fellows increased annually, up 54.1% from 1,606 in 2004-2005 to 2,475 in 2013-2014. The proportion of female critical care fellows increased from 29.5% (2004-2005) to 38.3% (2013-2014) (p < 0.001). The absolute number of black fellows increased each year but the percentage change was not statistically significantly different (5.1% in 2004-2005 vs 3.9% in 2013-2014; p = 0.92). Hispanic fellows increased in number from 124 (7.7%) in 2004-2005 to 216 (8.4%) in 2013-2014 (p = 0.015). The number of American Indian/Alaskan Native/Native Hawaiian/Pacific Islander fellows decreased from 15 (1.0%) to seven (0.3%) (p < 0.001). When compared with population estimates, female critical care fellows and those from racial/ethnic minorities were underrepresented in all years. The demographics of the emerging critical care physician workforce reflect underrepresentation of women and racial/ethnic minorities. Trends highlight increases in women and Hispanics and stable or decreasing representation of non-Hispanic underrepresented minority critical care fellows. Further research is needed to elucidate the reasons underlying

It is also of interest to scholars who are interested in the wider implications of reflection, for example,…

Thirty years of critical care medicine

PubMed Central

2010-01-01

Critical care medicine is a relatively young but rapidly evolving specialty. On the occasion of the 30th International Symposium on Intensive Care and Emergency Medicine, we put together some thoughts from a few of the leaders in critical care who have been actively involved in this field over the years. Looking back over the last 30 years, we reflect on areas in which, despite large amounts of research and technological and scientific advances, no major therapeutic breakthroughs have been made. We then look at the process of care and realize that, here, huge progress has been made. Lastly, we suggest how critical care medicine will continue to evolve for the better over the next 30 years.

This paper presents a critical reflection of the integration of Blended Learning (BL) into an undergraduate occupational therapy curriculum which was delivered through Problem Based Learning (PBL). This is a qualitative reflection of a Participatory Action Research (PAR) study using Brookfield's model for critical reflection of an educator's practice. The model uses four 'lenses' through which to focus enquiry: Lens 1) our autobiography as a learner of practice; Lens 2) our learners' eyes; Lens 3) our colleagues' experiences; and Lens 4) the theoretical literature. Grounded theory analysis was applied to the data. The factors that contributed to successful integration of technology and e-Learning into an existing curriculum, the hurdles that were navigated along the way, and how these influenced decisions and innovation are explored. The core categories identified in the data were "drivers of change" and "outcomes of BL integration". Key situations and pivotal events are highlighted for their role in the process that led to the project maturing. Each lens reflects the successes and hurdles experienced during the study. Brookfield's model provides an objective method of reflection which showed that despite the hurdles, e-Learning was successfully integrated into the curriculum.

Respiratory health of elite athletes - preventing airway injury: a critical review.

PubMed

Kippelen, Pascale; Fitch, Kenneth D; Anderson, Sandra Doreen; Bougault, Valerie; Boulet, Louis-Philippe; Rundell, Kenneth William; Sue-Chu, Malcolm; McKenzie, Donald C

2012-06-01

Elite athletes, particularly those engaged in endurance sports and those exposed chronically to airborne pollutants/irritants or allergens, are at increased risk for upper and lower airway dysfunction. Airway epithelial injury may be caused by dehydration and physical stress applied to the airways during severe exercise hyperpnoea and/or by inhalation of noxious agents. This is thought to initiate an inflammatory cascade/repair process that, ultimately, could lead to airway hyperresponsiveness (AHR) and asthma in susceptible athletes. The authors review the evidence relating to prevention or reduction of the risk of AHR/asthma development. Appropriate measures should be implemented when athletes exercise strenuously in an attempt to attenuate the dehydration stress and reduce the exposure to noxious airborne agents. Environmental interventions are the most important. Non-pharmacological strategies can assist, but currently, pharmacological measures have not been demonstrated to be effective. Whether early prevention of airway injury in elite athletes can prevent or reduce progression to AHR/asthma remains to be established.

Objective To summarize the current literature on racial and gender disparities in critical care and the mechanisms underlying these disparities in the course of acute critical illness. Data Sources MEDLINE search on the published literature addressing racial, ethnic, or gender disparities in acute critical illness such as sepsis, acute lung injury, pneumonia, venous thromboembolism, and cardiac arrest. Study Selection Clinical studies that evaluated general critically ill patient populations in the United States as well as specific critical care conditions were reviewed with a focus on studies evaluating factors and contributors to health disparities. Data Extraction Study findings are presented according to their association with the incidence, clinical presentation, management, and outcomes in acute critical illness. Data Synthesis This review presents potential contributors for racial and gender disparities related to genetic susceptibility, comorbidities, preventive health services, socioeconomic factors, cultural differences, and access to care. The data is organized along the course of acute critical illness. Conclusions The literature to date shows that disparities in critical care are most likely multifactorial involving individual, community, and hospital-level factors at several points in the continuum of acute critical illness. The data presented identify potential targets as interventions to reduce disparities in critical care and future avenues for research. PMID:24121467

Venous thromboembolism (VTE) is a common complication of acute illness, and its prevention is a ubiquitous aspect of inpatient care. A multicenter blinded, randomized trial compared the effectiveness of the most common pharmocoprevention strategies, unfractionated heparin (UFH) and the low-molecular-weight heparin (LMWH) dalteparin, finding no difference in the primary end point of leg deep-vein thrombosis but a reduced rate of pulmonary embolus and heparin-induced thrombocytopenia among critically ill medical-surgical patients who received dalteparin. To evaluate the comparative cost-effectiveness of LMWH vs UFH for prophylaxis against VTE in critically ill patients. Prospective economic evaluation concurrent with the Prophylaxis for Thromboembolism in Critical Care Randomized Trial (May 2006 to June 2010). The economic evaluation adopted a health care payer perspective and in-hospital time horizon; derived baseline characteristics and probabilities of intensive care unit and in-hospital events; and measured costs among 2344 patients in 23 centers in 5 countries and applied these costs to measured resource use and effects of all enrolled patients. Costs, effects, incremental cost-effectiveness of LMWH vs UFH during the period of hospitalization, and sensitivity analyses across cost ranges. Hospital costs per patient were $39,508 (interquartile range [IQR], $24,676 to $71,431) for 1862 patients who received LMWH compared with $40,805 (IQR, $24,393 to $76,139) for 1862 patients who received UFH (incremental cost, -$1297 [IQR, -$4398 to $1404]; P = .41). In 78% of simulations, a strategy using LMWH was most effective and least costly. In sensitivity analyses, a strategy using LMWH remained least costly unless the drug acquisition cost of dalteparin increased from $8 to $179 per dose and was consistent among higher- and lower-spending health care systems. There was no threshold at which lowering the acquisition cost of UFH favored prophylaxis with UFH. From a

The prevention of hospital acquired pressure ulcers in critically ill patients remains a significant clinical challenge. The aim of this trial was to investigate the effectiveness of multi-layered soft silicone foam dressings in preventing intensive care unit (ICU) pressure ulcers when applied in the emergency department to 440 trauma and critically ill patients. Intervention group patients (n = 219) had Mepilex(®) Border Sacrum and Mepilex(®) Heel dressings applied in the emergency department and maintained throughout their ICU stay. Results revealed that there were significantly fewer patients with pressure ulcers in the intervention group compared to the control group (5 versus 20, P = 0·001). This represented a 10% difference in incidence between the groups (3·1% versus 13·1%) and a number needed to treat of ten patients to prevent one pressure ulcer. Overall there were fewer sacral (2 versus 8, P = 0·05) and heel pressure ulcers (5 versus 19, P = 0·002) and pressure injuries overall (7 versus 27, P = 0·002) in interventions than in controls. The time to injury survival analysis indicated that intervention group patients had a hazard ratio of 0·19 (P = 0·002) compared to control group patients. We conclude that multi-layered soft silicone foam dressings are effective in preventing pressure ulcers in critically ill patients when applied in the emergency department prior to ICU transfer. © 2013 The Authors.

Hypoglycemia in Critically Ill Children

Faustino, E Vincent S; Hirshberg, Eliotte L; Bogue, Clifford W

2012-01-01

Background The practice of glycemic control with intravenous insulin in critically ill patients has brought clinical focus on understanding the effects of hypoglycemia, especially in children. Very little is published on the impact of hypoglycemia in this population. We aimed to review the existing literature on hypoglycemia in critically ill neonates and children. Methods We performed a systematic review of the literature up to August 2011 using PubMed, Ovid MEDLINE and ISI Web of Science using the search terms “hypoglycemia or hypoglyc*” and “critical care or intensive care or critical illness”. Articles were limited to “all child (0–18 years old)” and “English”. Results A total of 513 articles were identified and 132 were included for review. Hypoglycemia is a significant concern among pediatric and neonatal intensivists. Its definition is complicated by the use of a biochemical measure (i.e., blood glucose) for a pathophysiologic problem (i.e., neuroglycopenia). Based on associated outcomes, we suggest defining hypoglycemia as <40–45 mg/dl in neonates and <60–65 mg/dl in children. Below the suggested threshold values, hypoglycemia is associated with worse neurological outcomes, increased intensive care unit stay, and increased mortality. Disruptions in carbohydrate metabolism increase the risk of hypoglycemia incritically ill children. Prevention of hypoglycemia, especially in the setting of intravenous insulin use, will be best accomplished by the combination of accurate measuring techniques, frequent or continuous glucose monitoring, and computerized insulin titration protocols. Conclusion Studies on hypoglycemia in critically ill children have focused on spontaneous hypoglycemia. With the current practice of maintaining blood glucose within a narrow range with intravenous insulin, the risk factors and outcomes associated with insulin-induced hypoglycemia should be rigorously studied to prevent hypoglycemia and potentially improve

Implementing NICU critical thinking programs: one unit's experience.

PubMed

Zimmerman, Denise; Pilcher, Jobeth

2008-01-01

Critical thinking is the hallmark of today's nursing practice environment. Nowhere is this more critical than in the high-tech environment of the NICU. Despite the importance of critical thinking in nursing practice, there is limited information on the process of teaching new NICU nurses to think critically. Based on the principles of adult education, orientation and continuing education for NICU nurses should be goal directed, build on the learner's prior experience, and build in opportunities for active participation, reflection, and experiential learning. This article reviews the principles of adult education and their application to the process of teaching critical thinking in the NICU. One unit's experience of critical thinking education is used to provide concrete examples of how NICU education can be transformed from a traditional didactic methodology to a more dynamic experiential approach.

Exact Critical Exponents for the Antiferromagnetic Quantum Critical Metal in Two Dimensions

NASA Astrophysics Data System (ADS)

Schlief, Andres; Lunts, Peter; Lee, Sung-Sik

2017-04-01

Unconventional metallic states which do not support well-defined single-particle excitations can arise near quantum phase transitions as strong quantum fluctuations of incipient order parameters prevent electrons from forming coherent quasiparticles. Although antiferromagnetic phase transitions occur commonly in correlated metals, understanding the nature of the strange metal realized at the critical point in layered systems has been hampered by a lack of reliable theoretical methods that take into account strong quantum fluctuations. We present a nonperturbative solution to the low-energy theory for the antiferromagnetic quantum critical metal in two spatial dimensions. Being a strongly coupled theory, it can still be solved reliably in the low-energy limit as quantum fluctuations are organized by a new control parameter that emerges dynamically. We predict the exact critical exponents that govern the universal scaling of physical observables at low temperatures.

Reflective teaching of medical communication skills with DiViDU: assessing the level of student reflection on recorded consultations with simulated patients.

PubMed

Hulsman, R L; Harmsen, A B; Fabriek, M

2009-02-01

Acquisition of effective, goal-oriented communication skills requires both practicing skills and reflective thinking. Reflection is a cyclic process of perceiving and analysing communication behaviour in terms of goals and effects and designing improved actions. Based on Korthagen's ALACT reflection model, communication training on history taking was designed. Objectives were to develop rating criteria for assessment of the students' level of reflection and to collect student evaluations of the reflective cycle components in the communication training. All second year medical students recorded a consultation with a simulated patient. In DiViDU, a web-based ICT program, students reviewed the video, identified and marked three key events, attached written reflections and provided peer-feedback. Students' written reflections were rated on four reflection categories. A reflection-level score was based on a frequency count of the number of categories used over three reflections. Students filled out an evaluation questionnaire on components of the communication training. Data were analyzed of 304 (90.6%) students. The four reflection categories Observations, Motives, Effects and Goals of behaviour were used in 7-38%. Most students phrased undirected questions for improvement (93%). The average reflection score was 2.1 (S.D. 2.0). All training components were considered instructive. Acting was preferred most. Reviewing video was considered instructive. Self-reflection was considered more difficult than providing written feedback to the reflections of peers. Reflection on communication behaviour can be systematically implemented and measured in a structured way. Reflection levels were low, probably indicating a limited notion of goal-oriented attributes of communication skills. Early introduction of critical self-reflection facilitates acceptance of an important ability for physicians for continued life-long learning and becoming mindful practitioners.

Personality and cognitive processes: self-criticism and different types of rumination as predictors of suicidal ideation.

PubMed

O'Connor, Rory C; Noyce, Rosie

2008-03-01

Self-criticism and rumination have been related to suicidality. In the present study, we investigated the extent to which different types of rumination (brooding and reflection) mediate the relationship between self-criticism and suicidal ideation. Two hundred and thirty-two healthy adults completed a range of psychological inventories at Time 1 and were followed up approximately 3 months later (Time 2). Brooding was more strongly associated with suicidal ideation than reflection. Hierarchical regression analyses confirmed that among those who completed measures at both time points, brooding rumination fully mediated the self-criticism-Time 2 suicidal ideation relationship. Reflection did not mediate the self-criticism-suicidal ideation link. The findings support a growing corpus of research which highlights the utility of personality and cognitive factors in advancing our understanding of the suicidal process. The theoretical and clinical implications are discussed.

2010-01-01

The fostering of reflective capacity within medical education helps develop critical thinking and clinical reasoning skills and enhances professionalism. Use of reflective narratives to augment reflective practice instruction is well documented. At Warren Alpert Medical School of Brown University (Alpert Med), a narrative medicine curriculum innovation of students' reflective writing (field notes) with individualized feedback from an interdisciplinary faculty team (in pre-clinical years) has been implemented in a Doctoring course to cultivate reflective capacity, empathy, and humanism. Interactive reflective writing (student writer/faculty feedback provider dyad), we propose, can additionally support students with rites of passage at critical educational junctures. At Alpert Med, we have devised a tool to guide faculty in crafting quality feedback, i.e. the Brown Educational Guide to Analysis of Narrative (BEGAN) which includes identifying students' salient quotes, utilizing reflection-inviting questions and close reading, highlighting derived lessons/key concepts, extracting clinical patterns, and providing concrete recommendations as relevant. We provide an example of a student's narrative describing an emotionally powerful and meaningful event - the loss of his first patient - and faculty responses using BEGAN. The provision of quality feedback to students' reflective writing - supported by BEGAN - can facilitate the transformation of student to professional through reflection within medical education.

Bankruptcy Prevention: New Effort to Reflect on Legal and Social Changes.

Every corporation has an economic and moral responsibility to its stockholders to perform well financially. However, the number of bankruptcies in Slovakia has been growing for several years without an apparent macroeconomic cause. To prevent a rapid denigration and to prevent the outflow of foreign capital, various efforts are being zealously implemented. Robust analysis using conventional bankruptcy prediction tools revealed that the existing models are adaptable to local conditions, particularly local legislation. Furthermore, it was confirmed that most of these outdated tools have sufficient capability to warn of impending financial problems several years in advance. A novel bankruptcy prediction tool that outperforms the conventional models was developed. However, it is increasingly challenging to predict bankruptcy risk as corporations have become more global and more complex and as they have developed sophisticated schemes to hide their actual situations under the guise of "optimization" for tax authorities. Nevertheless, scepticism remains because economic engineers have established bankruptcy as a strategy to limit the liability resulting from court-imposed penalties.

Politics of prevention: The emergence of prevention science.

PubMed

Roumeliotis, Filip

2015-08-01

This article critically examines the political dimension of prevention science by asking how it constructs the problems for which prevention is seen as the solution and how it enables the monitoring and control of these problems. It also seeks to examine how prevention science has established a sphere for legitimate political deliberation and which kinds of statements are accepted as legitimate within this sphere. The material consists of 14 publications describing and discussing the goals, concepts, promises and problems of prevention science. The analysis covers the period from 1993 to 2012. The analysis shows that prevention science has established a narrow definition of "prevention", including only interventions aimed at the reduction of risks for clinical disorders. In publications from the U.S. National Institute of Drug Abuse, the principles of prevention science have enabled a commitment to a zero-tolerance policy on drugs. The drug using subject has been constructed as a rational choice actor lacking in skills in exerting self-control in regard to drug use. Prevention science has also enabled the monitoring and control of expertise, risk groups and individuals through specific forms of data gathering. Through the juxtaposition of the concepts of "objectivity" and "morality", prevention science has constituted a principle of delineation, disqualifying statements not adhering to the principles of prevention science from the political field, rendering ethical and conflictual dimensions of problem representations invisible. The valorisation of scientific accounts of drugs has acted to naturalise specific political ideals. It simultaneously marginalises the public from the public policy process, giving precedence to experts who are able to provide information that policy-makers are demanding. Alternative accounts, such as those based on marginalisation, poverty or discrimination are silenced within prevention science. Copyright © 2015 Elsevier B.V. All rights

2017-11-01

Based on the data of the BMSW instrument installed on the of SPEKTR-R spacecraft, as well as according to the data of instruments of the WIND spacecraft, etc., using two examples, the paper has studied the role of ions reflected from the front and associated structural features of quasi-perpendicular interplanetary shocks (IS) with the Alfvén Mach number M A lower than the first critical Mach number M c1 . It has been shown that BSs with the finite parameter 0.1 < β1 < 1 contain a small fraction of reflected protons, which play a significant role in forming the front structure (β1 is the ratio of gas-to-magnetic pressure before the shock front). In particular, in the case of a perpendicular shock recorded on August 24, 2013 (the angle between the magnetic field direction and the normal to the front θBn ≈ 85°), an IS with a small Mach number ( M A ≈ 1.4) and small β1 ≈ 0.2 is shown that the interactions of reflected ions with inflowing solar wind may result in the collisionless heating of ions in front of and behind it. The case of the oblique (θBn = 63°) IS on April 19, 2014 with a small Mach number ( M A ≈ 1.2) and small β1 ≈ 0.5 has been investigated. It has been found that, before the front, there is a sequence of trains of magnetosonic waves, the amplitude of which decreases to zero upon increasing their distance from the front. The mechanism of their formation is associated with the development of instability caused by the ions reflected from the front.

Anisotropic Babinet-Invertible Metasurfaces to Realize Transmission-Reflection Switching for Orthogonal Polarizations of Light

The electromagnetic properties of an extremely thin metallic checkerboard drastically change from resonant reflection (transmission) to resonant transmission (reflection) when the local electrical conductivity at the interconnection points of the checkerboard is switched. To date, such critical transitions of metasurfaces have been applied only when they have fourfold rotational symmetry, and their application to polarization control, which requires anisotropy, has been unexplored. To overcome this applicability limitation and open up alternative pathways for dynamic deep-subwavelength polarization control by utilizing critical transitions of checkerboardlike metasurfaces, we introduce a universal class of anisotropic Babinet-invertible metasurfaces enabling transmission-reflection switching for each orthogonally polarized wave. As an application of anisotropic Babinet-invertible metasurfaces, we experimentally realize a reconfigurable terahertz polarizer whose transmitting axis can be dynamically rotated by 90°.

A critical review of the effectiveness of educational interventions applied in HIV/AIDS prevention.

PubMed

Adelekan, Moruf

2017-01-01

A critical review of issues around the effectiveness of educational approaches applied in the field of HIV/AIDS prevention. Published papers, systematic reviews and technical reports were reviewed. The review has identified the large gap between the current state of the art and the ultimate goal of the education-based approaches contributing to the reduction of HIV incidence rates. Significant positive impact has been reported mainly on mediating factors to behavioural change (knowledge, attitude, and intentions). The reported impact on actual behaviour change has been weak and short-lived. Biological markers are not used in many studies as outcome measures and follow-up period is too short to facilitate the measurement of impact on behaviour change or biological markers. Several methodological flaws and cultural issues militate against effective programming. A guideline for standardising practice and research in school-based programme is available for use. There is only very modest evidence of the effectiveness of educational interventions as a result of several gaps in project design, implementation and follow-up. There is urgent need to raise practice and research standards. Educational interventions should utilise scientifically valid data gathering methods. Follow-up period should be long enough to allow for impact measurement. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

A durable highly reflective silver mirror characterized by high reflectance in a broad spectral range of about 300 nm in the UV to the far infrared (.about.10000 nm), as well as exceptional environmental durability. A high absorptivity metal underlayer is used which prevents the formation of a galvanic cell with a silver layer while increasing the reflectance of the silver layer. Environmentally durable overcoat layers are provided to enhance mechanical and chemical durability and protect the silver layer from corrosion and tarnishing, for use in a wide variety of surroundings or climates, including harsh or extreme environments.

Obesity is widespread, associated with several physical and psychosocial comorbidities, and is difficult to treat. Prevention of obesity across the lifespan is critical to improving the health of individuals and society. Screening and prevention efforts in primary care are an important step in addressing the obesity epidemic. Each period of human development is associated with unique risks, challenges, and opportunities for prevention and intervention. Screening tools for overweight/obesity, although imperfect, are quick and easy to administer. Screening should be conducted at every primary care visit and tracked longitudinally. Screening tools and cutoffs for overweight and obesity vary by age group. Copyright © 2016 Elsevier Inc. All rights reserved.

Fox, Jared

2015-01-01

Abstract The receipt of clinical preventive services is important for health promotion and prevention of illness, death, and disability for women in the United States. Today, the Affordable Care Act makes a variety of evidence-based preventive services available with no out-of-pocket cost to women with certain health insurance plans. Nevertheless, available service receipt data suggest receipt of the services for all American adults remains suboptimal. This article seeks to raise awareness about the critical gaps in the delivery of preventive services to women and highlight opportunities for women, primary care providers, and public health professionals to increase receipt of clinical preventive services among women.

To evaluate efficacy and safety of a novel device that combines an inferior vena cava (IVC) filter and central venous catheter (CVC) for prevention of pulmonary embolism (PE) in critically ill patients. In a multicenter, prospective, single-arm clinical trial, the device was inserted at the bedside without fluoroscopy and subsequently retrieved before transfer from the intensive care unit (ICU). The primary efficacy endpoint was freedom from clinically significant PE or fatal PE 72 hours after device removal or discharge, whichever occurred first. Secondary endpoints were incidence of acute proximal deep venous thrombosis (DVT), catheter-related thrombosis, catheter-related bloodstream infections, major bleeding events, and clinically significant thrombus (occupying > 25% of volume of filter) detected by cavography before retrieval. The device was placed in 163 critically ill patients with contraindications to anticoagulation; 151 (93%) were critically ill trauma patients, 129 (85%) had head or spine trauma, and 102 (79%) had intracranial bleeding. The primary efficacy endpoint was achieved for all 163 (100%) patients (95% confidence interval [CI], 97.8%-100%, P < .01). Diagnosis of new or worsening acute proximal DVT was time dependent with 11 (7%) occurring during the first 7 days. There were no (0%) catheter-related bloodstream infections. There were 5 (3.1%) major bleeding events. Significant thrombus in the IVC filter occurred in 14 (8.6%) patients. Prophylactic anticoagulation was not initiated for a mean of 5.5 days ± 4.3 after ICU admission. This novel device prevented clinically significant and fatal PE among critically ill trauma patients with low risk of complications. Copyright © 2017 SIR. Published by Elsevier Inc.

See, reflect, learn more: qualitative analysis of breaking bad news reflective narratives.

Breaking bad news (BBN) is a challenge that requires multiple professional competencies. BBN teaching often includes didactic and group role-playing sessions. Both are useful and important, but exclude another critical component of students' learning: day-to-day role-model observation in the clinics. Given the importance of observation and the potential benefit of reflective writing in teaching, we have incorporated reflective writing into our BBN course. The aim of this study was to enhance our understanding of the learning potential in reflective writing about BBN encounters and the ability to identify components that inhibit this learning. This was a systematic qualitative immersion/crystallization analysis of 166 randomly selected BBN narratives written by 83 senior medical students. We analysed the narratives in an iterative consensus-building process to identify the issues discussed, the lessons learned and the enhanced understanding of BBN. Having previously been unaware of, not invited to or having avoided BBN encounters, the mandatory assignment led students to search for or ask their mentors to join them in BBN encounters. Observation and reflective writing enhanced students' awareness that 'bad news' is relative and subjective, while shedding light on patients', families', physicians' and their own experiences and needs, revealing the importance of the different components of the BBN protocol. We identified diversity among the narratives and the extent of students' learning. Narrative writing provided students with an opportunity for a deliberative learning process. This led to deeper understanding of BBN encounters, of how to apply the newly taught protocol, or of the need for it. This process connected the formal and informal or hidden curricula. To maximise learning through reflective writing, students should be encouraged to write in detail about a recent observed encounter, analyse it according to the protocol, address different participants

Estimated critical conditions for UF{sub 4}-oil systems in fully oil-reflected spherical geometry

DOE Office of Scientific and Technical Information (OSTI.GOV)

Plaster, M.J.

Paraffinic oil has been exposed to UF{sub 6} gas in seal exhaust pumps and cascade equipment at the Portsmouth Gaseous Diffusion Plant. The resulting mixture is more nuclearly reactive than mixtures of UO{sub 2}F{sub 2} and H{sub 2}O and is not bounded by the subcritical mass limits presented in several nuclear criticality safety guides. The purpose of this analysis is to determine several critical parameters; specifically, (1) k{sub {infinity}} and the critical mass for several enrichments and moderation levels and (2) the mass limits for these mixtures. The estimated critical masses for the UF{sub 4}-oil systems are smaller than formore » the UO{sub 2}F{sub 2}-H{sub 2}O systems. The suggested mass limits for the UF{sub 4}-oil systems are 0.240, 0.280, 0.350, 0.430, and 0.670, and 1.170 kg {sup 235}U for enrichments of 100, 50, 20, 10, 5, and 3 wt.% {sup 235}U respectively.« less

This study attempts a critical evaluation of the clinical evidence behind the use of dietary pomegranate preparations in the prevention and treatment of cardiovascular diseases. A search of PubMed on August 10, 2014 identified 228 references, which yielded extractable data from 24 clinical studies of pomegranate preparations. Hand searching identified two further studies. The quality of the studies and evidence of effectiveness of pomegranate were assessed by an established set of conventional criteria. Overall, the study quality was poor. Even in the best studies, indications of benefit did not reach the conventional levels of statistical significance. The only study with a definitive design had a biochemical rather than a clinical endpoint: it showed the expected difference in blood concentrations of myeloperoxidase after a single dose of either pomegranate or placebo. Only 10 of the 26 studies provided HPLC data on the amounts of co-active ingredients in the preparations that were consumed by the subjects. If pomegranate has a role in the prevention and treatment of cardiovascular diseases, there is a pressing need for dose-finding and long-term confirmatory studies. The ultimate endpoint for definitive studies would be mortality, but reductions in blood pressure or demonstrable decreases in atherosclerotic plaques would be useful surrogates. Sample sizes for various assumptions are provided. Future studies need to prove the clinical benefit. Copyright © 2015 John Wiley & Sons, Ltd.

To evaluate the impact of a dedicated specialist critical care pharmacist service on patient care at a UK critical care unit (CCU). Pharmacist intervention data was collected in two phases. Phase 1 was with the provision of a non-specialist pharmacist chart review service and Phase 2 was after the introduction of a specialist dedicated pharmacy service. Two CCUs with established critical care pharmacist services were used as controls. The impact of pharmacist interventions on optimising drug therapy or preventing harm from medication errors was rated on a 4-point scale. There was an increase in the mean daily rate of pharmacist interventions after the introduction of the specialist critical care pharmacist (5.45 versus 2.69 per day, P < 0.0005). The critical care pharmacist intervened on more medication errors preventing potential harm and optimised more medications. There was no significant change to intervention rates at the control sites. Across all study sites the majority of pharmacist interventions were graded to have at least moderate impact on patient care. The introduction of a specialist critical care pharmacist resulted in an increased rate of pharmacist interventions compared to a non-specialist pharmacist service thus improving the quality of patient care. © 2016 The Authors.

The neuropsychology of self-reflection in psychiatric illness

PubMed Central

Philippi, Carissa L.; Koenigs, Michael

2014-01-01

The development of robust neuropsychological measures of social and affective function—which link critical dimensions of mental health to their underlying neural circuitry—could be a key step in achieving a more pathophysiologically-based approach to psychiatric medicine. In this article, we summarize research indicating that self-reflection (the inward attention to personal thoughts, memories, feelings, and actions) may be a useful model for developing such a paradigm, as there is evidence that self-reflection is (1) measurable with self-report scales and performance-based tests, (2) linked to the activity of a specific neural circuit, and (3) dimensionally related to mental health and various forms of psychopathology.
