    Full Text Available This article uses data obtained from a content analysis of job advertisements to explore the questions of (1 what types of non-traditional jobs are available for library and information science (LIS professionals and (2 how can LIS students and professionals take advantage of non-traditional job opportunities. Two groups of job advertisements were used in this investigation: advertisements from LIS-targeted job boards (two library school job boards and two library association job boards and Government of Canada internal job postings. These two sets of job postings were selected to compare the competencies in job postings targeted to LIS graduates (the LIS job board advertisements and job postings that were not targeted to the LIS community (the Government of Canada job advertisements. An analysis of these groups of job advertisements demonstrated that both samples focused mainly on transferable competencies. Due to the emphasis on transferable competencies, the analysis of job postings from the Government of Canada job list revealed that there are many non-traditional opportunities for LIS graduates. A typical LIS professional could apply for 51 (or 25.8% of the job advertisements in this set, having met all of the listed criteria. This individual may be able to apply for an additional 40 (or 21.2% of the jobs listed if they had certain additional competencies or knowledge obtained through prior experience working in the Government of Canada but not necessarily obtained by the average LIS professional. This supports the argument that there are numerous opportunities for LIS professionals in non-traditional jobs. The exploration of commonly requested competencies can be used to guide LIS job seekers to craft their resumes and CVs to address the competencies requested by potential employers.

    Manfrin-Ledet, Linda; Porche, Demetrius J; Eymard, Amanda S

    2015-06-01

    The purpose of this article is to review the nursing literature related to professional boundary violations in nursing. A search was conducted using CINAHL, MEDLINE, Ebscohost, and NCSBN. The key words searched were professional boundaries, boundary violation, boundary crossings, nurse, home health nurses, and home nursing. The search returned over 40 publications related specifically to boundary violations and nursing although only four of them are published research studies and one as a dissertation. Seven common characteristics emerged from the nonresearch nursing articles on professional boundaries: (1) Dual relations/role reversal, (2) Gifts and money, (3) Excessive self-disclosure, (4) Secretive behavior, (5) Excessive attention/overinvolvement, (6) Sexual behavior, and (7) Social media. Additional nursing research is greatly needed in the area of professional boundaries. The nurse-patient relationship should always be maintained for the benefit of the patient and not the personal gain of the nurse. Ongoing education in nursing practice regarding professional boundaries is needed. Nurses need to be mindful of state practice acts, codes of conduct, and employer policies.

    .Information‐related (Access to Information, Information Sources5.Social web‐related (Names of Blogs, Names of Social NetworksThe tag analysis resulted in the following percentages of distribution:•33.62% of the tags associated with LIS blogs were general in nature•20.21% of the tags were technology‐related•19.12% of the tags were library‐related•14.60% of the tags were information‐related•12.90% of the tags were related to the social webThese percentages add up to 100.45%. The author makes no mention of this oddity and it is assumed to be an error.The researcher attempted to determine if tags and folksonomies form a consistent scheme. In reporting her findings, she concluded that four major categories of professional‐related content were revealed, which reflect the blogger‐librarians’ fields of interest. The prominence of the general category revealed that bloggers’ personal interests and experiences were written about more often. As well, it appears that although bloggers seem to assign non‐related tags randomly, the analysis shows that tags still can be categorized.Conclusion – The researcher concludes that this study is helpful for librarians and information scientists because it can help them to navigate the LIS blogosphere. She reports that the categories of tags beyond the general category, which mainly contains tags related to bloggers’ personal interests and experiences, shows that blogs can contribute to professional development. Although more informal in nature, the research has shown that LIS blogs do contain professional information, and it behooves professionals to become familiar with the tag scheme in topic oriented blogs, and to try to work within the scheme to make use of the content within. The researcher suggests further ideas for research, including the differences in LIS blogs written by a single blogger as compared with blogs written by multiple authors, as well as gender differences between male and female authored blogs

    2015-06-27

    Medical school curricula, although traditionally and historically dominated by science, have generally accepted, appreciated, and welcomed the inclusion of literature over the past several decades. Recent concerns about medical professional formation have led to discussions about the specific role and contribution of literature and stories. In this article, we demonstrate how professionalism and the study of literature can be brought into relationship through critical and interrogative interactions based in the literary skill of close reading. Literature in medicine can question the meaning of "professionalism" itself (as well as its virtues), thereby resisting standardization in favor of diversity method and of outcome. Literature can also actively engage learners with questions about the human condition, providing a larger context within which to consider professional identity formation. Our fundamental contention is that, within a medical education framework, literature is highly suited to assist learners in questioning conventional thinking and assumptions about various dimensions of professionalism.

These adult learners developed a deeper understanding of and how children read, learn concepts and respond to text and they enhanced their understandings of multiple perspectives. Teacher candidates indicated that co-learning in the context of a literature circle helped them in their transformation into professional teachers as they experienced and reflected on learners, learning and teaching/learning strategies. Many revised their definitions of ‘teacher’ as a result of their experiences in intergenerational literature circles.

    2008-01-01

    The idea that health professionals should be accountable to the society they serve is not a new concept and by the 1990 s, the continuing professional development (CPD) of health professionals was being seen as one way in which Canadians' level of health could be improved. The public was, and is still today, increasingly demanding a system that is more responsive to regional and community needs. As a result, there is a need for more health professional education at all stages of the education continuum - undergraduate, postgraduate, and continuing professional development - that meets the health and social needs of the populations being served. The trend is now towards 'socially accountable' health care, meaning that the broader context of CPD must also include the personal, social, and political aspects of health care and as such, involve a widening of accountability to patients, the community, managers and policymakers. CPD planning must take into account local and national priorities as well as personal learning needs. However, the definition of social accountability and the stages at which it is addressed is sometimes vague and this added to the difficulty of identifying relevant studies in the literature. Nonetheless, there were some "best practices" evident via Canadian and American studies which focused on models of socially accountable CPD, as well as examples of interdisciplinary collaboration in Canada, the United States, Australia, Great Britain, and the United Arab Emirates. However, there is a definite need for increased research and publication of such "best practice" initiatives. There is also a need for Canadian health professional schools to facilitate this process by sharing their experiences and resources if possible. An extensive literature review was conducted between January and March 2004. Due to time constraints, it was limited to articles written in the English language. The databases/sources utilized included: Medline (now known as Pubmed

    To review the literature in order to evaluate how health professionals promote and support breastfeeding. Studies from the following databases were retrieved: Scopus, PubMed, Medline, Lilacs, SciELO, Web of Science and Cumulative Index to Nursing and Allied Health Literature (Cinahl). The descriptors "breastfeeding", "professional role" and "patient care team" were used in the research. The review was limited to articles in Portuguese, Spanish, and English published between 1997 and 2013. The search retrieved 1,396 studies, 18 of which were selected for being directly relevant to the main question. The review showed that breastfeeding is a challenge for health professionals, regardless of their specialization, as they have to face a demand that requires skill and sensibility, for which they are not prepared. Health professionals have considered breastfeeding a purely instinctive and biological act. Moreover, it is noticeable that many of them possess theoretical expertise on the subject, but lack the practical skills. Health professionals need to be better trained to work on promoting breastfeeding, whether by health and medical schools or by healthcare administrators, in order to consolidate multiprofessional teams committed to maternal-infant health.

Skills that were coded had to be noted in such a way that the employer plainly stated the employee would be a certain skill or attribute or they were seeking a skill or a particular skill was essential or desirable. Skills that were stated in synonymous ways within the same advertisement were counted as two incidences of that skill. Duties for the position were not counted unless they were listed as a specific skill. Data were all coded by hand and then tallied.

Older adults experience high rates of morbidity and health care usage, and frequently transit between health services, and community and social care providers. These transition episodes place elders at increased risk of adverse incidents due to poor communication of information. Integrated multi-professional models of care built on enhanced communication have been widely promoted as a strategy to improve transitional care for older people. However, a range of findings exist in the literature to guide service providers and researchers. Comprehensive literature search and review strategies were employed to identify, describe and synthesise relevant studies. Ten databases were searched in addition to Google Scholar. Specified discharge worker roles, multi-professional care coordination teams, and information technology systems promote better service satisfaction and subjective quality of life for older people when compared with standard hospital discharge. Improved multi-professional communication reduces rates of re-admission and length of stay indicating greater cost effectiveness and efficiency for the health and social care systems. Systems of care emphasizing information exchange, education and negotiation between stakeholders facilitate communication in transitional care contexts for older adults. Conversely, lack of dialogue and lack of understanding of others' roles are barriers to communication in transitional care. Enhanced multi-professional communication, transitional pathways, and role clarity are required to improve the quality, sustainability and responsiveness of aged care into the future.

    The completion of the Human Genome Project has enhanced avenues for disease prevention, diagnosis, and management. Owing to the shortage of genetic professionals, genetics/genomics training has been provided to nongenetic health professionals for years to establish their genomic competencies. We conducted a systematic literature review to summarize and evaluate the existing genetics/genomics education programs for nongenetic health professionals. Five electronic databases were searched from January 1990 to June 2016. Forty-four studies met our inclusion criteria. There was a growing publication trend. Program participants were mainly physicians and nurses. The curricula, which were most commonly provided face to face, included basic genetics; applied genetics/genomics; ethical, legal, and social implications of genetics/genomics; and/or genomic competencies/recommendations in particular professional fields. Only one-third of the curricula were theory-based. The majority of studies adopted a pre-/post-test design and lacked follow-up data collection. Nearly all studies reported participants' improvements in one or more of the following areas: knowledge, attitudes, skills, intention, self-efficacy, comfort level, and practice. However, most studies did not report participants' age, ethnicity, years of clinical practice, data validity, and data reliability. Many genetics/genomics education programs for nongenetic health professionals exist. Nevertheless, enhancement in methodological quality is needed to strengthen education initiatives.Genet Med advance online publication 20 October 2016.

    The increased physical demands of professional athletes predispose this patient population to a unique set of injuries typically not seen in the general population. This systematic literature review investigates the nature of injury reporting (both orthopedic and nonorthopedic conditions) in the medical literature of professional athletes in the National Football League (NFL), Major League Baseball (MLB), the National Basketball Association (NBA), and the National Hockey League (NHL). Rigorous reporting of sports injuries helps clinicians better understand disease mechanisms relevant to specific sports. The nature of injury reporting will differ within each professional sport and reflect the anatomic emphasis of each sport. An electronic literature search of all publications addressing injuries and medical conditions among professional athletes in the NFL, MLB, NBA, and NHL was conducted using the Pubmed/Medline, Scopus, and Embase databases through January 2013. Retrieved publications were categorized by journal type, medical type, and area of focus. A total of 536 publications met all inclusion criteria. There were a higher number of articles regarding the NFL (n = 211) and MLB (n = 216) when compared with the NBA (n = 34) or NHL (n = 75). The NFL had significantly more articles addressing nonorthopedic injuries/medical issues than were found with the MLB, NBA, or NHL (109 vs 75, 14, 41, respectively). Both the NFL (33 of 109, 30%) and NHL (6 of 41, 15%) had a relatively high percentage of articles regarding concussions/neurology, and MLB had a relatively high percentage of articles dedicated to vascular medicine (13 of 65, 20%). The proportion of publications dedicated to the knee/lower leg were highest in the NFL (29 of 102, 28%) and NBA (9 of 20, 45%), those dedicated to the shoulder/elbow were highest in MLB (113 of 151, 75%), and those dedicated to the hip/pelvis were highest in the NHL (16 of 34, 47%). The number and type of publications vary among the 4

    Psychiatric practice in India is marked by an increasing gulf between largely urban-based mental health professionals and a majority rural population. Based on the premise that any engagement is a mutually constructed humane process, an understanding of the culture of psychiatry including social process of local knowledge acquisition by trainee psychiatrists is critical. This paper reviews existing literature on training of psychiatrists in India, the cultural construction of their professional identities and autobiographical reflections. The results reveal a scarcity of research on how identities, knowledge, and values are constructed, contested, resisted, sustained, and operationalized through practice. This paper hypothesizes that psychiatric training and practice in India continues to operate chiefly in an instrumental fashion and bears a circular relationship between cultural, hierarchical training structures and patient–carer concerns. The absence of interpretative social science training generates a professional identity that predominantly focuses on the patient and his/her social world as the site of pathology. Infrequent and often superfluous critical cultural reflexivity gained through routine clinical practice further alienates professionals from patients, caregivers, and their own social landscapes. This results in a peculiar brand of theory and practice that is skewed toward a narrow understanding of what constitutes suffering. The authors argue that such omissions could be addressed through nuanced ethnographies on the professional development of psychiatrists during postgraduate training, including the political economies of their social institutions and local cultural landscapes. Further research will also help enhance culturally sensitive epistemology and shape locally responsive mental health training programs. This is critical for majority rural Indians who place their trust in State biomedical care. PMID:28529358

    The healthcare setting is a rich learning environment for students to experience interprofessional working (IPW) and interprofessional education (IPE). However, opportunities for IPE are limited, and student experiences of effective IPW are varied. This raises the question of how IPW and IPE are valued by health or social care professionals. A search of the literature was carried out to identify studies of health and social care staff attitudes to IPW and IPE. This review provides a summary of the main factors found to influence attitudes and the strengths and limitations of these studies. Professional background and prior IPE experience were identified as the influencing factors for which there is most evidence. The main limitations of the studies accessed included a focus on the value of IPE for staff, as opposed to students, and a limited number of studies considering the relationship between attitudes to IPW and the value placed on IPE. It is important that health and social care professionals lead by example by working collaboratively and providing students with opportunities for IPE. Identifying the variables influencing attitudes to IPW and IPE may assist in improving IPW and experiences of IPE for students learning in the healthcare setting.

    Routinely collected clinical data is increasingly used for health service management, audit, and research. Even apparently anonymised data are subject to data protection. The relevant principles were set out in a treaty of the Council of Europe and subsequent policy has been based on these. However, little has been written about implementing policy and the role of health informaticians in this process. To define the elements of an effective implementation policy; the role of the health informatician in protecting processed clinical data. We performed a literature review of bibliographic databases, a manual search of the major medical informatics associations' websites, relevant working groups and an affiliated journal. Fifty-four papers relevant to implementation were identified. The effective implementation of policy requires consideration of technical, organisational, personnel and professional issues. However, there is no clearly defined formula for successful implementation of data protection policy. Patients and professionals need a system they can trust, and processes that can be easily incorporated into everyday practice. The lack of a core generalisable theory or strong professional code in health informatics limits the ability of the health informaticians to implement policy.

  13. LIS1 controls mitosis and mitotic spindle organization via the LIS1–NDEL1–dynein complex

    Heterozygous LIS1 mutations are responsible for the human neuronal migration disorder lissencephaly. Mitotic functions of LIS1 have been suggested from many organisms throughout evolution. However, the cellular functions of LIS1 at distinct intracellular compartments such as the centrosome and the cell cortex have not been well defined especially during mitotic cell division. Here, we used detailed cellular approaches and time-lapse live cell imaging of mitosis from Lis1 mutant mouse embryonic fibroblasts to reveal critical roles of LIS1 in mitotic spindle regulation. We found that LIS1 is required for the tight control of chromosome congression and segregation to dictate kinetochore–microtubule (MT) interactions and anaphase progression. In addition, LIS1 is essential for the establishment of mitotic spindle pole integrity by maintaining normal centrosome number. Moreover, LIS1 plays crucial roles in mitotic spindle orientation by increasing the density of astral MT plus-end movements toward the cell cortex, which enhances cortical targeting of LIS1–dynein complex. Overexpression of NDEL1–dynein and MT stabilization rescues spindle orientation defects in Lis1 mutants, demonstrating that mouse LIS1 acts via the LIS1–NDEL1–dynein complex to regulate astral MT plus-ends dynamics and establish proper contacts of MTs with the cell cortex to ensure precise cell division.

    Full Text Available In the literature on the evolution of funding approaches there is criticism of traditional funding strategies and the promotion of inclusive models, such as South-South Cooperation (SSC and triangular models. The latter are felt to have a number of advantages. This article has four broad objectives: (i to present a literature review on the evolution of Southern approaches to development co-operation; (ii to indicate examples of current co-operative programmes in health and health professional education in Africa; (iii to assess the advantages and disadvantages of these models; and (iv to mention some emerging issues in monitoring and evaluation. The Boolean logic approach was used to search for applicable literature within three topic layers. Searches were conducted using PubMed, PLoS and other accessible databases. An initial draft of the article was presented to a group of academics and researchers at the Flemish Inter-University Council (VLIR-UOS-Primafamed annual workshop held in August 2010 in Swaziland. Comments and suggestions from the group were included in later versions of the article. It is important to note that the existence of various funding models implemented by a variety of actors makes it difficult to measure their effects. In health and health professional education, however, SSC and triangular models of aid provide conditions for more effective programming through their focus on participation and long-term involvement. With an eye towards evaluating programmes, a number of salient issues are emerging. The importance of context is highlighted.

    Increasing emphasis on community-based mandates an examination of the community health nurse (CHN). A critical literature review of the CHN role internationally, with an emphasis on Australia, was undertaken in order to understand historical precedents and inform policy and strategic directions for the CHN. A search of the CINAHL, EMBASE, and COCHRANE electronic data-bases from 1982 to June 2002 using community' and 'nursing' as key words and hand searching of books and government reports was undertaken. This search strategy revealed a lack of literature compared with other areas of nursing. Key themes emerging from this review are: (1) an absence of clear role definitions and lack of clarity of roles; (2) variability in educational requirements for CHNs; (3) diminished CHN power in policy decision making; (3) conflicting role expectations between different facets of the health care system; (4) underutilisation and untapped potential of the role of the CHN in the contemporary health care system; (5) the emerging influence of specialist nurses in community based-care; (6) uptake of traditional nursing roles by non-nurses and (7) an absence of a cohesive model of professional development of CHN that is able to articulate with contemporary social, political and economic trends in health care delivery. Community health nursing in Australia has a low professional profile when compared to other nursing specialties. An emerging issue, gleaned from the literature review is the tension and debate between specialist and generalist services. It is apparent from this review that CHN have to more actively participate in research and peer reviewed debate in order to have their voice heard and promote their unique and valuable contribution to the nursing profession and the health care system.

    Statistical literacy and knowledge is needed to read and understand the public health literature. The purpose of this study was to quantify basic and advanced statistical methods used in public health research. We randomly sampled 216 published articles from seven top tier general public health journals. Studies were reviewed by two readers and a standardized data collection form completed for each article. Data were analyzed with descriptive statistics and frequency distributions. Results were summarized for statistical methods used in the literature, including descriptive and inferential statistics, modeling, advanced statistical techniques, and statistical software used. Approximately 81.9% of articles reported an observational study design and 93.1% of articles were substantively focused. Descriptive statistics in table or graphical form were reported in more than 95% of the articles, and statistical inference reported in more than 76% of the studies reviewed. These results reveal the types of statistical methods currently used in the public health literature. Although this study did not obtain information on what should be taught, information on statistical methods being used is useful for curriculum development in graduate health sciences education, as well as making informed decisions about continuing education for public health professionals.

  18. Mindfulness, self-compassion, and empathy among health care professionals: a review of the literature.

    Science.gov (United States)

    Raab, Kelley

    2014-01-01

    The relationship between mindfulness and self-compassion is explored in the health care literature, with a corollary emphasis on reducing stress in health care workers and providing compassionate patient care. Health care professionals are particularly vulnerable to stress overload and compassion fatigue due to an emotionally exhausting environment. Compassion fatigue among caregivers in turn has been associated with less effective delivery of care. Having compassion for others entails self-compassion. In Kristin Neff's research, self-compassion includes self-kindness, a sense of common humanity, and mindfulness. Both mindfulness and self-compassion involve promoting an attitude of curiosity and nonjudgment towards one's experiences. Research suggests that mindfulness interventions, particularly those with an added lovingkindness component, have the potential to increase self-compassion among health care workers. Enhancing focus on developing self-compassion using MBSR and other mindfulness interventions for health care workers holds promise for reducing perceived stress and increasing effectiveness of clinical care.

    2014-12-01

    The aim of this study was to examine the effectiveness of interventions designed to reduce mental illness stigma among healthcare students and professionals. A literature search was conducted using the Cochrane Library and PubMed. Randomised controlled trial level evidence demonstrated that interventions involving direct contact, indirect filmed contact or an educational email effectively reduced stigma in the short term. Role play was the only intervention with randomised controlled trial level evidence demonstrating no effect. There was not enough evidence to suggest that any intervention can maintain stigma reduction over time. Stigma reduction in healthcare students and professionals needs to be sustained over time if it is to result in positive changes for people living with mental illness. Further research is needed to determine which interventions, if any, can achieve this. Only then will large-scale implementation of a stigma reduction intervention be feasible and beneficial to people living with mental illness. © The Royal Australian and New Zealand College of Psychiatrists 2014.

  1. Patient and professional dissatisfaction: a literature review of prognosis communication related to hospital settings.

    Science.gov (United States)

    Bail, Kasia

    2008-06-01

    An essential element of health care decision making is related to 'what is going to happen next' (or prognosis). Patients are often dissatisfied with prognosis communication (Chan & Woodruff 1997; Kirk, Kirk & Kristjanson 2004). Yet there is a paucity of literature on the contributing factors and resulting consequences of prognosis communication. A thematic analysis on prognosis communication applicable to hospital wards was employed. The thematic analysis revealed that patients are dissatisfied with prognosis communication, and this dissatisfaction is related to information giving, understanding, and decision making. There is also evidence to suggest that health care professionals are also distressed and dissatisfied with the current use of prognosis in health care delivery, and this relates to hope, role discrepancies, and emotional labour. Factors identified in the literature as contributing to the current use of prognosis included difficulty with the definition, estimation and communication of prognosis. The contributing factor of the medical model upon prognosis communication is discussed. The suggestion is made that if both consumers and providers are dissatisfied with current prognosis communication, then there should be sufficient relevant research funded, undertaken and utilised to inform training, policy changes and individual clinical practice reflection in the movement towards more patient-focussed, sustainable health care.

    Teamwork is seen as an important element of patient care in acute hospital settings. The complexity of the journey of care for patients highlights the need for health professionals to collaborate and communicate clearly with each other. Health organizations in western countries are committed to improving patient safety through education of staff and teamwork education programs have been integral to this focus. There are no current systematic reviews of the experience of health professionals who participate in teamwork education in acute hospital settings. The objective of this systematic review was to search for the best available evidence on the experiences of health professionals who participate in teamwork education in acute hospital settings. This review considered studies reporting on experiences of registered health professionals who work in acute hospitals. This included medical, nursing and midwifery and allied health professionals. The focus of the meta-synthesis was the experiences and reflections of health professionals who were involved in teamwork education in acute hospital settings. The geographical context for this review was acute hospitals in rural or metropolitan settings in Australia and overseas countries. The review focused on the experiences of health professionals who work in acute hospitals and participated in teamwork education programs. This review considered studies that focused on qualitative data including, but not limited to, designs such as phenomenology, grounded theory, ethnography, action research and feminist research.In the absence of research studies, other text such as opinion papers, discussion papers and reports were considered. Studies published in English and from 1990 to 2013 were included in this review. The literature search for relevant papers occurred between 13 September and 26 October 2013. A three-step search strategy was utilized in this review. The databases searched were PubMed, CINAHL, Embase and Scopus. The

    To comprehensively review the Community of Practice literature from nursing contexts to explore whether and how these communities contribute to the social construction of nurse educator professional identity. Due to the wide scope of predominately qualitative literature on the topic, papers were analysed and themed inductively. CINAHL, MEDLINE, COCHRANE, EBSCO databases, Emerald, Proquest & Google Scholar. These online databases were searched for relevant peer-reviewed journal papers in the English language with no date range specified. The search terms 'nurs* educator' and 'nurs* teacher' were combined with each of the terms 'communit* of practice', 'identity' and 'role' resulting in 293 peer-reviewed journal papers. Where abstracts were missing, introductory and background sections were skimmed for related content. Papers that made incidental reference to either professional identity or a Community of Practice were excluded. In total, 63 primary study or discussion papers were found to have a focus on nurse educator identity and/or communities of practice in healthcare contexts. Papers specifically focused on communities of practice in nursing (n=33) could only be found from the last 10 years (2005-2015). Only five of these focused on nurse educators. Community of Practice theory and the professional teaching literature offers collaborative and active ways for nurse educators to further develop their professional identities. Despite the emergence of communities of practice in the nursing literature, further studies are required to explore how such a construct can facilitate the social construction of nurse educator professional identity.

    Full Text Available The article deals the questions of properties and biological role of nitric oxide molecule, which is characterized with vasodilating, stress limiting and neurotransmitter properties, and participates in reactions of oxidative stress, glutamate and calcium cascade and inflammation. Researches of the relationship of endothelial NO-synthase and the risk of cardiovascular, ischemic and respiratory diseases in population of untrained persons and athletes continue. The aim of this study was to establish, according to the literature, the present state of the influence of endothelial NO-synthase gene polymorphism on the formation of the physical qualities of strength, endurance and speed in professional athletes, its changes and influence on functional state of athlete. At the present stage of development of medical genetics it is proved, that the implementation of the action of each individual isoform of the enzyme NO-synthase is caused by the presence of polymorphism. The most studied are the T-786С polymorphism of the eNOS gene promoter, G894T (Glu298Asp polymorphism of the 7th exon, 4a/b–4th intron of eNOS, but their influence is not definitively proven, and is caused by the presence of homo- or heterozygotes.

    Full Text Available The demands of the job market in the information field trigger the need to improve professional practices that refer to the curricular reform, due to the formation of competent professionals that meet the social needs. Archivists, when categorized as information professionals, also fit into this context, and must acquire the status of a Modern Information Professional (MIP. Thus, this study analyzes the skills of the MIP relating them to the archivist, based on literature and curricular training. Investigates in literature what has been published about the MIP; Compares MIP's skills to the archivist's; And investigates these skills in the field of archival training. Methodologically, a review of the MIP's skills and its relations to the archivists' and analysis of ten curricula of Brazilian archival schools was carried out, in order to detect subjects focused on the construction of MIP skills. After theoretical and documentary research, it was noticed that most of the studies (80% compare the MIP to the librarian. The literature is scarce (10% by directing the MIP to the archivist, but also without delineating it to specific professionals (10%. As for the academic formation, the schools, in general lines, offer subjects, whose curricular approach contemplates the four competences of the MIP. It was found that schools recognize the need to extend the skills of archivists to the point where they become MIPs, in order to adapt to the new challenges posed by the job market.

    2016-11-01

    To understand the motivations and experiences of health and social care professionals undertaking part-time, accredited, continuing professional education in higher education. A review following systematic principles. Systematic searches for literature published between January 2000 and December 2015 using the databases: SCOPUS, Web of Science, Medline, PsychINFO, Social Policy and Practice and CINAHL. Studies were included if they were published in the English language and were qualitative in design, focussing on the motivations and experiences of staff engaged in part-time, accredited, higher education study. Three reviewers appraised the quality of the selected studies. Thirteen qualitative studies were identified for the review. Motivating factors for staff to engage in part-time, accredited, continuing professional development study included: personal and professional drivers, influence of workplace/management and funding and availability. Key themes in relation to how staff experienced study included: the demands of adjusting to the academic requirements of higher education study; the experience of juggling competing demands of study, work and family; and the presence or absence of support for part-time study in the personal and professional arenas. Health and social care professionals experience a number of challenges when engaging in part-time, continuing professional education in higher education institutions. A significant challenge is the juggling of competing demands of study, work and family, and this may have a negative impact on learning. Research is needed to inform how higher education can address the specific learning needs of this population and develop pedagogic approaches that are both responsive to need and support of effective learning.

    The aim of the study was to complete a collaborative review of Radiography continuing professional development (CPD) research material to support the production of European Federation of Radiographer Societies (EFRS) CPD recommendations. A meta-ethnography approach to literature review was applied focussing upon commonalities rather than discrepancies between research outcomes. This facilitated exploration of context across the geographical region of Europe with national variations in CPD governance. The seven phases of the meta-ethnographic approach were followed by two independent experienced researchers. A third researcher mediated the findings which were then explored collaboratively with the EFRS CPD working group for concordance. Phase seven of the meta-ethnography involved interpreting an expression of the synthesis from the previous stages. Six main corroborating themes emerged in this process and following mediation were expressed as themes; knowledge, skills & competency, needs/gap analysis, multi-layered/multi-modal, barriers and drivers; regulation vs autonomy; fostering collaboration - harnessing technology. The primary feature of CPD activity should be the resulting impact - to patients, the service, the profession and the individual; with all stakeholders working in partnership. CPD activity must be flexible/multi-modal to support the changing growth/dynamic workforce. All stakeholders should utilise communication and technology resources and make efforts to improve collaboration between the management, regulators and educators to support Radiographers to develop meaningful CPD. Health services across Europe are under increasing stress and a principal factor going forwards will be managing increasing demands on healthcare staff whilst supporting enhancement of the knowledge, skills and competency base.

    Substitution of skills has been introduced to increase health service efficiency, but little evidence is available about its cost-effectiveness. This systematic review aims to identify economic evaluations of substitution between professionals, to assess the quality of the study methods applied and to value the results for decision making. Publications between January 1996 and November 2006 were searched in Medline, Cochrane, Cinahl, database of Health Technology Assessments, EPOC and Embase. Randomized controlled trials (RCTs), cost-benefit analysis, interrupted time series design and systematic reviews were selected. The methodological quality of the papers was reviewed, using the critical appraisal of Drummond and the EPOC list. Eleven studies were finally included of 7605 studies: three cost-effectiveness studies, three cost-minimization studies and five studies related to partial economic evaluations. Small numbers of participating professionals and several limitations in the cost valuation and the measurement of costs were identified. Several potential limitations influence the validity and generalizability. Full economic evaluations per se are of limited value for making decisions about substitution of skills. The tenuous relationship between structural, process and outcome variables is not sufficient investigated. For meaningfully placing the costs and consequences of substitution of skills in the context of health care and generating relevant data for decision making, it is strongly recommended to combine an economic evaluation (RCT) with an observational longitudinal study.

    Full Text Available This article deals with scientific approaches to professional competencies development of future software engineers, described in the local and foreign literature. It was found, that software development process usually occurs in the context of software project management. According to various papers, the major challenge in the area of software project management is the high failure rate of software development projects. One of the main factors contributing to the failure of software development projects is that people, involved in the process, including software engineers, do not possess certain soft competencies, essential to the project success. Conducted a literature review of studies, published on the topic of professional competencies development of future software engineers. Found that for now there are plenty of papers on and scientific approaches to professional soft competencies development of future software engineers. As per the analysis in the article, present scientific approaches can be divided into three groups: ones, based on the correspondent extracurricular activities; ones, based on project-oriented learning, and ones, based on the use of Information and Communication Technologies, for example, game simulators in combination with lectures and educational projects. The above-mentioned groups of approaches are described in more details, broken down by papers of particular authors.

  10. What do bereaved parents want from professionals after the sudden death of their child: a systematic review of the literature.

    Garstang, Joanna; Griffiths, Frances; Sidebotham, Peter

    2014-10-15

    The death of a child is a devastating event for parents. In many high income countries, following an unexpected death, there are formal investigations to find the cause of death as part of wider integrated child death review processes. These processes have a clear aim of establishing the cause of death but it is less clear how bereaved families are supported. In order to inform better practice, a literature review was undertaken to identify what is known about what bereaved parents want from professionals following an unexpected child death. This was a mixed studies systematic review with a thematic analysis to synthesize findings. The review included papers from Europe, North America or Australasia; papers had to detail parents' experiences rather than professional practices. The review includes data from 52 papers, concerning 4000 bereaved parents. After a child has died, parents wish to be able to say goodbye to them at the hospital or Emergency Department, they would like time and privacy to see and hold their child; parents may bitterly regret not being able to do so. Parents need to know the full details about their child's death and may feel that they are being deliberately evaded when not given this information. Parents often struggle to obtain and understand the autopsy results even in the cases where they consented for the procedure. Parents would like follow-up appointments from health care professionals after the death; this is to enable them to obtain further information as they may have been too distraught at the time of the death to ask appropriate questions or comprehend the answers. Parents also value the emotional support provided by continuing contact with health-care professionals. All professionals involved with child deaths should ensure that procedures are in place to support parents; to allow them to say goodbye to their child, to be able to understand why their child died and to offer the parents follow-up appointments with appropriate

    Technological supports aiming to change the behaviour of healthcare professionals show considerable promise, particularly those involving computer-generated reminders and feedback. Due to the lack of theoretically-informed interventions, we were unable to draw conclusions around the effectiveness of theory-behaviour change interventions in this context. Interventions currently lack consistency in delivery method and content, which future research should address.

    Speaking up is important for patient safety, but often, health care professionals hesitate to voice concerns. Understanding the influencing factors can help to improve speaking-up behaviour and team communication. This review focused on health care professionals' speaking-up behaviour for patient safety and aimed at (1) assessing the effectiveness of speaking up, (2) evaluating the effectiveness of speaking-up training, (3) identifying the factors influencing speaking-up behaviour, and (4) developing a model for speaking-up behaviour. Five databases (PubMed, MEDLINE, CINAHL, Web of Science, and the Cochrane Library) were searched for English articles describing health care professionals' speaking-up behaviour as well as those evaluating the relationship between speaking up and patient safety. Influencing factors were identified and then integrated into a model of voicing behaviour. In total, 26 studies were identified in 27 articles. Some indicated that hesitancy to speak up can be an important contributing factor in communication errors and that training can improve speaking-up behaviour. Many influencing factors were found: (1) the motivation to speak up, such as the perceived risk for patients, and the ambiguity or clarity of the clinical situation; (2) contextual factors, such as hospital administrative support, interdisciplinary policy-making, team work and relationship between other team members, and attitude of leaders/superiors; (3) individual factors, such as job satisfaction, responsibility toward patients, responsibility as professionals, confidence based on experience, communication skills, and educational background; (4) the perceived efficacy of speaking up, such as lack of impact and personal control; (5) the perceived safety of speaking up, such as fear for the responses of others and conflict and concerns over appearing incompetent; and (6) tactics and targets, such as collecting facts, showing positive intent, and selecting the person who has

    2013-09-01

    Nursing professionals are integral members of the healthcare team and they maintain the most direct and prolonged contact with patients experiencing a terminal illness. This integrative review of the literature sought to investigate the attitude towards death among nursing professionals and students. Data were collected through searches in Lilacs, Medline, PsycINFO and CINAHL databases using the key words "nurses" and "attitude to death" in the period from 2000 to 2011. Of the 1376 articles identified, 262 were selected for data extraction and 35 were downloaded in full, constituting the corpus of research. The results showed a predominance of articles published in Brazilian journals. Studies indicate that the subject of death and dying has been neglected in training institutions, which causes hardship among professionals and nursing students when faced with the issue in practice, in addition to inappropriate conduct when dealing with patients who are experiencing the end of life process. In conclusion, the need for future research that may provide more detailed clarifications on the subject and seek strategies to address the lack of preparation and support of the nursing staff when they cope with death and dying was emphasized.

    Our aim was to obtain a clearer picture of the relevant care experiences and care perceptions of incurably ill Turkish and Moroccan patients, their relatives and professional care providers, as well as of communication and decision-making patterns at the end of life. The ultimate objective is to improve palliative care for Turkish and Moroccan immigrants in the Netherlands, by taking account of socio-cultural factors in the guidelines for palliative care. A systematic literature review was undertaken. The data sources were seventeen national and international literature databases, four Dutch journals dedicated to palliative care and 37 websites of relevant national and international organizations. All the references found were checked to see whether they met the structured inclusion criteria. Inclusion was limited to publications dealing with primary empirical research on the relationship between socio-cultural factors and the health or care situation of Turkish or Moroccan patients with an oncological or incurable disease. The selection was made by first reading the titles and abstracts and subsequently the full texts. The process of deciding which studies to include was carried out by two reviewers independently. A generic appraisal instrument was applied to assess the methodological quality. Fifty-seven studies were found that reported findings for the countries of origin (mainly Turkey) and the immigrant host countries (mainly the Netherlands). The central themes were experiences and perceptions of family care, professional care, end-of-life care and communication. Family care is considered a duty, even when such care becomes a severe burden for the main female family caregiver in particular. Professional hospital care is preferred by many of the patients and relatives because they are looking for a cure and security. End-of-life care is strongly influenced by the continuing hope for recovery. Relatives are often quite influential in end-of-life decisions, such

    Background Our aim was to obtain a clearer picture of the relevant care experiences and care perceptions of incurably ill Turkish and Moroccan patients, their relatives and professional care providers, as well as of communication and decision-making patterns at the end of life. The ultimate objective is to improve palliative care for Turkish and Moroccan immigrants in the Netherlands, by taking account of socio-cultural factors in the guidelines for palliative care. Methods A systematic literature review was undertaken. The data sources were seventeen national and international literature databases, four Dutch journals dedicated to palliative care and 37 websites of relevant national and international organizations. All the references found were checked to see whether they met the structured inclusion criteria. Inclusion was limited to publications dealing with primary empirical research on the relationship between socio-cultural factors and the health or care situation of Turkish or Moroccan patients with an oncological or incurable disease. The selection was made by first reading the titles and abstracts and subsequently the full texts. The process of deciding which studies to include was carried out by two reviewers independently. A generic appraisal instrument was applied to assess the methodological quality. Results Fifty-seven studies were found that reported findings for the countries of origin (mainly Turkey) and the immigrant host countries (mainly the Netherlands). The central themes were experiences and perceptions of family care, professional care, end-of-life care and communication. Family care is considered a duty, even when such care becomes a severe burden for the main female family caregiver in particular. Professional hospital care is preferred by many of the patients and relatives because they are looking for a cure and security. End-of-life care is strongly influenced by the continuing hope for recovery. Relatives are often quite influential in

    Epidemiologic evidence of a protective role for fruits and vegetables in cancer prevention is substantial. The strength of this scientific base guides US national policymaking in diet and health issues and facilitates community and local programs that address national dietary goals to increase fruit and vegetable consumption. Current scientific evidence also suggests a protective role for fruits and vegetables in prevention of coronary heart disease, and evidence is accumulating for a protective role in stroke. In addition, a new scientific base is emerging to support a protective role for fruits and vegetables in prevention of cataract formation, chronic obstructive pulmonary disease, diverticulosis, and possibly, hypertension. This article provides an overview of the health benefits associated with fruit and vegetable consumption for each of these conditions, including brief discussions of underlying protective mechanisms, identifies key scientific findings regarding the health benefits of fruit and vegetable consumption, and outlines applications of these findings for dietetics professionals. The evidence reviewed provides additional support for increased consumption of a wide variety of vegetables, in particular, dark-green leafy, cruciferous, and deep-yellow-orange ones, and a wide variety of fruits, in particular, citrus and deep-yellow-orange ones. Continued attention to increasing fruit and vegetable consumption is a practical and important way to optimize nutrition to reduce disease risk and maximize good health.

    2012-12-01

    A small proportion of patients with orofacial pain appearing to dentists and dental specialists will have intracranial tumors as the underlying cause. These patients may undergo unnecessary dental interventions before the correct diagnosis is made. A search of the literature using the PubMed database was performed to identify case reports of this occurrence. Cases were analyzed for common characteristics or presenting features that may aid dentists in identifying patients with intracranial tumors. Twenty-eight cases were identified. Features consistent with the diagnoses of trigeminal neuralgia, persistent idiopathic facial pain, and temporomandibular disorders were the most common presentations. Fifty-nine percent of patients presented with sensory or motor function loss at their initial diagnosis. Patients who present with symptoms that extend beyond the typical presentation of these entities are at highest risk for intracranial tumors and should be further evaluated.

The authors determined that 65% of the variance in the data was explained by two factors: students’ responses to library stereotypes and students’ self-reported reasons for choosing to study LIS. The self-reported reasons for studying LIS were combined into four variables (extrinsic reasons, intrinsic professional reasons, intrinsic academic reasons, and intrinsic social reasons to be used in the multivariate analysis of variance tests (MANOVAs.Three distinct clusters of students were found using the indices and parental education level in cluster analysis: Cluster 1 (low parental education, low Educational Career, and low Divergence indices scores, Cluster 2 (intermediate parental education, high Educational Career, and low Divergence scores, and Cluster 3 (high parental education, high Educational Career, and low Divergence scores. For three of the factors for choosing the LIS field (intrinsic professional reasons, intrinsic academic reasons, and intrinsic social reasons, Cluster 1 showed statistically significant differences (pConclusion — The authors concluded that students with different socio-cultural characteristics have different reasons for choosing LIS as a field of study and differ in their abilities to make competent decisions about their education. Students with high socio-cultural resources choose LIS for its intrinsic values and are able to make competent decisions. Students with low socio-cultural resources cannot make informed decisions regarding their chosen career paths and choose LIS purely for the prospect of future employment.

    To explore the debate on the development of the nurse practitioner profession in the Netherlands. In the Netherlands, the positives and negatives of nurse practitioners working in the medical domain have been debated since the role was introduced in 1997. The outcome of the debate is crucial for nurse practitioners' professional development and society's justification of their tasks. Review of 14 policy documents, 35 opinion papers from nurses, 363 opinion articles from physicians and 24 Dutch research papers concerning nurse practitioners from 1995 to 2012. Two discourses were revealed: one related to efficiency and one to the development of the profession. In both, the nurse practitioner role was presented as a solution for healthcare and workforce problems, while arguments differed. The efficiency discourse seemed most influential. Opinions of nurse practitioners were underrepresented; taking up new responsibilities was driven by the wish to improve patient care. While most physicians were willing to delegate tasks to nurse practitioners, they wished to retain final responsibility for medical care. All available publications were extensively studied, which could not include unpublished policy documents from the government or influential parties. This may have led to some selectivity. The case of the Netherlands shows that nurses in developing their advanced role are facing barriers, similar to those in other countries. The dominance of efficiency arguments combined with protection of medical autonomy undermines the development towards nursing care that really benefits patients. Nurse practitioners should strive to obtain positions in which they are allowed to make their own decisions and wise use of healthcare resources for the good of patients and society. Nurse practitioners should aim to become members of influential healthcare Boards in their countries, in which they can raise their voices and be involved in policy making. © 2013 International Council of

  15. Parenthood, information and support on the internet. A literature review of research on parents and professionals online

    2009-05-01

    Full Text Available Abstract Background The aim of this article was to address questions on how parents use the internet to find information and support regarding children, health and family life. Another aim was to find out how professionals use the internet to provide support and information to parents. This was done by a literature review. Methods Articles were searched for in five databases with a search strategy called "building block" approach. Results The review showed that the majority of today's parents search for both information and social support on the internet. However, there are considerable differences due to gender, age and socio-economic differences. First time middle class mothers aged 30–35 are most active in looking up health and parent information on the internet. In the same time, several studies report diminishing class differences on parent web sites. An important reason to the increasing number of parents who turn to the internet for information and interaction has shown to be the weakened support many of today's parents experience from their own parents, relatives and friends. Professionals have recognized the parents' great interest for going online and offer both information and support on the net. Conclusion Many benefits are reported, for example the possibility to reach out to a wider audience and to increase access to organisations without an increase in costs. Other benefits include the possibility for parents to remain anonymous in their contacts with professionals and that parents' perceived need for information can be effectively met around the clock. Interventions for wider groups of parents, such as parent training on the net, are still very rare and more research is needed to evaluate different types of interventions on the net. However, most studies were empirical and lacked theoretical frameworks which leave questions on how we can more fully understand this phenomenon unanswered.

    The primary goal of this project was to describe the level of knowledge acquisition using detailed test performance outcomes of the EBD SAPL curriculum over its first 7-years of implementation at the NYU College of Dentistry. A secondary goal was to compare performance outcomes impact of the full 60 h base SAPL curriculum as taught to 4-year DDS students vs an abbreviated 30 h base SAPL curriculum as taught to 3-year Advanced Placement DDS students. The findings for the period 2004-2010 are reported for 1647 dental students (63.6% 4-year DDS students, 36.3% 3-year Advanced Placement DDS students). The database consisted of the score earned by each student on each individual question of the SAPL course's 4 h final examination in which each student read an original research article and answered all questions on the Literature Analysis Form. The major findings were overall high performance by both groups of students (SAPL exam scores of 85.8 vs 83.7, respectively) as well as very similar outcomes between these two student groups on: 1) recognizing research design elements and on interpreting those design elements for clinical application, 2) detailed performance of knowledge within the specific five traditional sections of research articles, and 3) detailed performance across 18 identified research design topics. In conclusion, both course formats appear to be highly effective for their respective student groups, but should not be interpreted as evidence favoring the shorter format given the different characteristics of the two student groups.

    2012-01-01

    Recruitment and retention of allied health professionals (AHPs) to remote and rural Australia is challenging and correlates with poorer health status of remote and rural residents. While much has been written about the recruitment and retention problem, this study took a new approach by reviewing the literature describing the motivation of AHPs to work in remote and rural areas and then analyzing the findings from the perspective of motivation theory using Herzberg's extrinsic and intrinsic classification. Intrinsic motivation incentives are known to contribute to job satisfaction and come from within the individual, for example the pleasure derived from autonomy or challenge at work. In contrast, extrinsic motivation incentives are provided by the job and include such factors as salary and professional development provisions. Extrinsic incentives are important because they prevent job dissatisfaction. Job satisfaction has been shown to be linked with increased retention. Thirty-five articles, including 26 from Australia, met the inclusion criteria. The key findings related to motivation from each article are outlined and the results classified into the extrinsic-intrinsic framework. The incentives are then further analyzed as having a positive or a negative influence. In total, 38 different incentives were described a total of 246 times. Of the total, almost half (n=115) comprised extrinsic incentives with a negative influence, with poor access to professional development, professional isolation and insufficient supervision the most frequently reported. Rural lifestyle and diverse caseloads were the most frequently mentioned positive extrinsic incentives, while autonomy and community connectedness were the most cited positive intrinsic incentives. Negative intrinsic incentives were mentioned least frequently (n=18); however, of these, feeling overwhelmed and that your work was not valued by the community were the most commonly reported. The results demonstrate the

    This review was conducted to explore the literature to determine the availability, content, and evaluation of existing chemical, biological, radiological, and nuclear (CBRN) education programs for health professionals. An integrative review of the international literature describing disaster education for CBRN (2004-2016) was conducted. The following relevant databases were searched: Proquest, Pubmed, Science Direct, Scopus, Journals @ OVID, Google Scholar, Medline, and Ichuschi ver. 5 (Japanese database for health professionals). The search terms used were: "disaster," "chemical," "biological," "radiological," "nuclear," "CBRN," "health professional education," and "method." The following Medical Subject Headings (MeSH) terms, "education," "nursing," "continuing," "disasters," "disaster planning," and "bioterrorism," were used wherever possible and appropriate. The retrieved articles were narratively analyzed according to availability, content, and method. The content was thematically analyzed to provide an overview of the core content of the training. The literature search identified 619 potentially relevant articles for this study. Duplicates (n=104) were removed and 87 articles were identified for title review. In total, 67 articles were discarded, yielding 20 articles for all-text review, following 11 studies were retained for analysis, including one Japanese study. All articles published in English were from the USA, apart from the two studies located in Japan and Sweden. The most typical content in the selected literature was CBRN theory (n=11), followed by studies based on incident command (n=8), decontamination (n=7), disaster management (n=7), triage (n=7), personal protective equipment (PPE) use (n = 5), and post-training briefing (n=3). While the CBRN training course requires the participants to gain specific skills and knowledge, proposed training courses should be effectively constructed to include approaches such as scenario-based simulations

    Objective To identify whether laypeople and professionals rate the facial appearance of patients with cleft lip and palate (CLP) similarly based on viewing full facial images. Design Several electronic databases were searched. A hand search was performed among reference lists and relevant journals. Studies that assessed the full facial appearance of patients with CLP based on two-dimensional (2D) photographs, 3D images, or clinical examination by laypeople and professionals using a visual analog scale (VAS) or a categorical rating scale were included. Two authors independently assessed articles using methodologic-quality scoring protocol. Results Eleven articles were included in qualitative synthesis, including four high-level and seven moderate-level papers. Three studies found that laypeople were more critical than professionals, three found there was no significant difference between laypeople and professionals, and five reported that professionals were more critical than laypeople when assessing facial appearance of patients with CLP. Conclusions It still remains unknown whether laypeople are more or less critical than professionals when rating facial appearance of patients with repaired CLP. Professionals are more familiar with the esthetic outcomes and difficulties of treating patients. The opposite maybe true for laypeople; this disparity between what is achievable by professionals and what is expected by laypeople may be a source of dissatisfaction in facial appearance outcome. Further well-designed studies should be carried out to address this question and the clinical significance of the difference in rating scores for patients with CLP.

  12. Leading Process Branch Instability in Lis1+/− Nonradially Migrating Interneurons

    Science.gov (United States)

    Gopal, Pallavi P.; Simonet, Jacqueline C.; Shapiro, William

    2010-01-01

    Mammalian forebrain development requires extensive migration, yet the mechanisms through which migrating neurons sense and respond to guidance cues are not well understood. Similar to the axon growth cone, the leading process and branches of neurons may guide migration, but the cytoskeletal events that regulate branching are unknown. We have previously shown that loss of microtubule-associated protein Lis1 reduces branching during migration compared with wild-type neurons. Using time-lapse imaging of Lis1+/− and Lis1+/+ cells migrating from medial ganglionic eminence explant cultures, we show that the branching defect is not due to a failure to initiate branches but a defect in the stabilization of new branches. The leading processes of Lis1+/− neurons have reduced expression of stabilized, acetylated microtubules compared with Lis1+/+ neurons. To determine whether Lis1 modulates branch stability through its role as the noncatalytic β regulatory subunit of platelet-activating factor (PAF) acetylhydrolase 1b, exogenous PAF was applied to wild-type cells. Excess PAF added to wild-type neurons phenocopies the branch instability observed in Lis1+/− neurons, and a PAF antagonist rescues leading process branching in Lis1+/− neurons. These data highlight a role for Lis1, acting through the PAF pathway, in leading process branching and microtubule stabilization. PMID:19861636

  13. Partitioning the LIS/OTD Lightning Climatological Dataset into Separate Ground and Cloud Flash Distributions

    Science.gov (United States)

    Koshak, W. J.; Solarkiewicz, R. J.

    2009-01-01

    Presently, it is not well understood how to best model nitrogen oxides (NOx) emissions from lightning because lightning is highly variable. Peak current, channel length, channel altitude, stroke multiplicity, and the number of flashes that occur in a particular region (i.e., flash density) all influence the amount of lightning NOx produced. Moreover, these 5 variables are not the same for ground and cloud flashes; e.g., cloud flashes normally have lower peak currents, higher altitudes, and higher flash densities than ground flashes [see (Koshak, 2009) for additional details]. Because the existing satellite observations of lightning (Fig. 1) from the Lightning Imaging Sensor/Optical Transient Detector (LIS/OTD) do not distinguish between ground and cloud fashes, which produce different amounts of NOx, it is very difficult to accurately account for the regional/global production of lightning NOx. Hence, the ability to partition the LIS/OTD lightning climatology into separate ground and cloud flash distributions would substantially benefit the atmospheric chemistry modeling community. NOx indirectly influences climate because it controls the concentration of ozone and hydroxyl radicals in the atmosphere. The importance of lightning-produced NOx is empasized throughout the scientific literature (see for example, Huntrieser et al. 1998). In fact, lightning is the most important NOx source in the upper troposphere with a global production rate estimated to vary between 2 and 20 Tg (N)yr(sup -1) (Lee et al., 1997), with more recent estimates of about 6 Tg(N)yr(sup -1) (Martin et al., 2007). In order to make accurate predictions, global chemistry/climate models (as well as regional air quality modells) must more accurately account for the effects of lightning NOx. In particular, the NASA Goddard Institute for Space Studies (GISS) Model E (Schmidt et al., 2005) and the GEOS-CHEM global chemical transport model (Bey et al., 2001) would each benefit from a partitioning of the

The purposes were to: (1 test the model’s efficacy in supporting student growth related to core LIS concepts, practices, professional identity, and leadership skills, and (2 develop methods for formative and summative assessment using the model.Methods ‐ Using design‐based research principles to guide the formative and summative assessments, pre‐, mid‐, and post‐course questionnaires were constructed to test the model and administered to students in three LIS courses taught by the author. Participation was voluntary and anonymous. A total of 34 students completed the three courses; response rate for the questionnaires ranged from 47% to 95%. The pre‐course questionnaire addressed attitudes toward technology and the use of technology for learning. The mid‐course questionnaire addressed strengths and weaknesses of the course and suggestions for improvement. The post‐course questionnaire addressed what students valued about their learning and any changes in attitude toward technology for learning. Data were analyzed on three levels. Micro‐level analysis addressed technological factors related to usability and participant skills and attitudes. Meso‐level analysis addressed social and pedagogical factors influencing community learning. Macro‐level analysis addressed CoP learning outcomes, namely, knowledge of core concepts and practices, and the development of professional identity and leadership skills.Results ‐ The students can be characterized as adult learners who were neither early nor late adopters of technology. At the micro‐level, responses indicate that the online tools met high standards of usability and effectively supported online communication and learning. Moreover, the increase in positive attitudes toward the use of technology for learning at

    Under-diagnosed and uncontrolled symptoms in patients with prostate cancer during radiotherapy can have a negative impact on the individual's quality of life. An opportunity for patients to report their symptoms systematically, communicate these symptoms to cancer nurses and to receive self-care advice via an application in an Information and Communication Technology-platform could overcome this risk. The content in the application must precisely capture symptoms that are significant to both patients and health care professionals. Therefore, the aim of the study was to map and describe symptoms and self-care strategies identified by patients with prostate cancer undergoing radiotherapy, by health care professionals caring for these patients, and in the literature. The study combines data from interviews with patients (n = 8) and health care professionals (n = 10) and a scoping review of the literature (n = 26) focusing on the period during and up to 6 months after radiotherapy. There was a concordance between the patients, health care professionals, and the literature on symptoms during and after radiotherapy. Urinary symptoms, bowel problems, pain, sexual problems, fatigue, anxiety, depression, cognitive impairment and irregular symptoms were commonly described during the initial treatment period. Self-care strategies were rarely described in all three of the sources. The results show which symptoms to regularly assess using an Information and Communication Technology-platform for patients with newly-diagnosed prostate cancer during radiotherapy. The next step is to evaluate the efficacy of using the platform and the accuracy of the selected symptoms and self-care advice included in a smartphone application. Copyright © 2015 Elsevier Ltd.

    2018-02-08

    Through a systematic search of English language peer-reviewed studies, we assess how health professionals and the public, worldwide, perceive the health implications of climate change. Among health professionals, perception that climate change is harming health appears to be high, although self-assessed knowledge is low, and perceived need to learn more is high. Among the public, few North Americans can list any health impacts of climate change, or who is at risk, but appear to view climate change as harmful to health. Among vulnerable publics in Asia and Africa, awareness of increasing health harms due to specific changing climatic conditions is high. Americans across the political and climate change opinion spectra appear receptive to information about the health aspects of climate change, although findings are mixed. Health professionals feel the need to learn more, and the public appears open to learning more, about the health consequences of climate change.

  4. What do we know about student resilience in health professional education? A scoping review of the literature.

    2017-11-01

    Resilience has been identified as a key capability to thrive in the complex changing work environment of the 21st century. Therefore, the aim of this scoping review was to investigate how resilience is understood in the context of pre-qualifying health education, if there is a need to build student resilience, and what approaches to enhancing student resilience are described in the literature. Arksey and O'Malley's (2005) literature scoping review design was adopted as it enables researchers to review, summarise and analyse the literature on a given topic. The databases searched were Cumulative Index of Nursing and Allied Health Literature, Scopus, Proquest, Medline, Science Direct, and Education Resources Information Centre. Four research questions informed the literature review: (1) how is resilience conceptualised in the literature?, (2) what evidence exists for the need for resilience enhancement?, (3) what resilience factors should inform resilience enhancement?, and (4) what resilience enhancement programs are described in the literature? A total of 36 papers were reviewed in detail. Whilst the need for a focus on resilience across the health professions was evident an array of definitions and conceptualisations of resilience were described. A small number of approaches to enhancing resilience were identified. Whilst widespread recognition of the importance of resilience in the health professions exists the area remains under theorised with limited conceptual models and robust interventions published to date.

    2013-05-01

    Clostridium difficile is the most common health care-associated infection. Despite considerable efforts to prevent and manage C difficile, poor clinical practice and nonadherence to policy continues to compromise patient safety. Risk perception research is essential in gaining understanding about how health care professionals respond. A structured literature review examined empirical evidence regarding health care professionals' risk perceptions and responses toward C difficile. Because of limited evidence available, the review was extended to include other health care-associated infections. Only studies related to methicillin-resistant Staphylococcus aureus (MRSA) could be identified. Eleven studies were included. Four were specific to C difficile and 7 to MRSA. All studies found that technical understanding of C difficile was poor and that staff were concerned about risks to patients and themselves. Technical understanding for MRSA, however, was good, and staff were less concerned about their own health. Information provision was perceived to be inadequate and untrustworthy, which included the media. Practice in most studies was poor. There is a need to build on the efforts of risk perception research from other disciplines to understand how health care professionals think and make decisions about C difficile. This can help inform the development of effective management and communication strategies to maximize the quality of care provided.

Design – Web-based survey distributed via email. Setting – Accredited library and information science (LIS programs in North America. Subjects – 276 professors and professors emeriti. Methods – Researchers collected email addresses for 1,017 tenure-track, tenured, and emeriti professors from the public websites of the LIS programs. Researchers sent an email invitation to participate in the survey by accessing a URL, with the survey itself delivered using Qualtrics software. The survey included 51 total questions, some with additional sub-questions, and most items used Likert-type rating scale. The researchers analysed the data using SPSS software, and indicated using chi-square tests to measure significance, with a stated intent to get beyond the descriptive statistics commonly seen in other publications. Main Results – This study’s results draw on 276 completed responses, for a response rate of 27%. Researchers reported that 53% of respondents had some experience with publishing in a peer-reviewed OA format. When asked whether they agreed that scholarly articles should be free to access for everyone, pre-tenure assistant professors were most likely to agree (74%, followed by tenured associate professors (62%, full professors (59% and then emeriti professors (8%. However, they found less likelihood that associate professors would have actually published in an OA format, highlighting a “disconnect between beliefs about accessibility of research and actual practice with open access” (p. 646.

    Noting the upstream positioning of sustainable food systems (SFS) to multiple global crises, the present review described examples of emerging and promising practices to support SFS-oriented education, practical training (PT) and continuing professional development (CPD) among trainees and public health practitioners (PHP). A secondary objective was to compile the evidence into practical considerations for educators, supervising practitioners and professional associations. A scoping review of the literature published between 2007 and 2017 was conducted in May 2017 using four databases: CINAHL, MEDLINE, Scopus and HSSA, along with bibliography hand-searching and expert consultation. Articles were screened for relevance and specificity by independent raters. Nineteen articles were included for analysis. Two-thirds of the articles related to dietitians and public health nutritionists. Emerging practices included curriculum-based considerations, incorporation of 'sustainability' within professional competencies and self-reflection related to SFS. Descriptions of SFS-related education, PT and CPD practices appeared largely in the literature from developed countries. Articles converged on the need for ecosystems, food systems and sustainability considerations within and across practice to support current and future practitioners. There is growing interest in SFS but guidance to support educators and preceptors is lacking. Updates to dietary guidelines to reflect issues of sustainability are a timely prompt to examine the education, training and development needs of trainees and PHP. Practical examples of emerging practices can empower PHP to promote SFS in all areas of practice. More research is needed to address identified gaps in the literature and to improve SFS-specific education, PT and CPD.

  14. Lis1 Regulates Germinal Center B Cell Antigen Acquisition and Affinity Maturation.

    The germinal center (GC) is the site where activated B cells undergo rapid expansions, somatic hypermutation, and affinity maturation. Affinity maturation is a process of Ag-driven selection. The amount of Ag acquired and displayed by GC B cells determines whether it can be positively selected, and therefore Ag acquisition has to be tightly regulated to ensure the efficient affinity maturation. Cell expansion provides sufficient quantity of GC B cells and Abs, whereas affinity maturation improves the quality of Abs. In this study, we found that Lis1 is a cell-intrinsic regulator of Ag acquisition capability of GC B cells. Lack of Lis1 resulted in redistribution of polymerized actin and accumulation of F-actin at uropod; larger amounts of Ags were acquired and displayed by GC B cells, which presumably reduced the selection stringency. Affinity maturation was thus compromised in Lis1-deficient mice. Consistently, overexpression of Lis1 in GC B cells led to less Ag acquisition and display. Additionally, Lis1 is required for GC B cell expansion, and Lis1 deficiency blocked the cell cycle at the mitotic phase and GC B cells were prone to apoptosis. Overall, we suggest that Lis1 is required for GC B cell expansion, affinity maturation, and maintaining functional intact GC response, thus ensuring both the quantity and quality of Ab response.

  15. Role of the nuclear migration protein Lis1 in cell morphogenesis in Ustilago maydis

    2010-01-01

    Ustilago maydis is a basidiomycete fungus that exhibits a yeast-like and a filamentous form. Growth of the fungus in the host leads to additional morphological transitions. The different morphologies are characterized by distinct nuclear movements. Dynein and α-tubulin are required for nuclear movements and for cell morphogenesis of the yeast-like form. Lis1 is a microtubule plus-end tracking protein (+TIPs) conserved in eukaryotes and required for nuclear migration and spindle positioning. Defects in nuclear migration result in altered cell fate and aberrant development in metazoans, slow growth in fungi and disease in humans (e.g. lissencephaly). Here we investigate the role of the human LIS1 homolog in U. maydis and demonstrate that it is essential for cell viability, not previously seen in other fungi. With a conditional null mutation we show that lis1 is necessary for nuclear migration in the yeast-like cell and during the dimorphic transition. Studies of asynchronous exponentially growing cells and time-lapse microscopy uncovered novel functions of lis1: It is necessary for cell morphogenesis, positioning of the septum and cell wall integrity. lis1-depleted cells exhibit altered axes of growth and loss of cell polarity leading to grossly aberrant cells with clusters of nuclei and morphologically altered buds devoid of nuclei. Altered septum positioning and cell wall deposition contribute to the aberrant morphology. lis1-depleted cells lyse, indicative of altered cell wall properties or composition. We also demonstrate, with indirect immunofluorescence to visualize tubulin, that lis1 is necessary for the normal organization of the microtubule cytoskeleton: lis1-depleted cells contain more and longer microtubules that can form coils perpendicular to the long axis of the cell. We propose that lis1 controls microtubule dynamics and thus the regulated delivery of vesicles to growth sites and other cell domains that govern nuclear movements. PMID:20524583

    Full Text Available In this paper we investigate citation practices of scientific literature in reflexive writing from the genre of supervised pre-service training report produced by pre-service teachers enrolled in the mandatory pre-service training subject of English Language Teaching, at an undergraduate language teaching course. The aim of this research is to analyze how these pre-services teacher represent themselves based on citation practices of scientific literature, and characterize some of the functions deployed by the citations in the reflexive writing emerging in the academic sphere. We use the dialogic approach to language from Bakhtinian studies as a theoretical base, as well as theoretical and methodological contributions regarding types of sequences and of discourse proposed by Adam and Bronckart. The results of this research show that the practice of citation of scientific literature is an invocation of authority as a form of erudition, amplification and ornamentation of the discourse produced. This practice can also guide pedagogical action developed by pre-service teachers in their supervised training.

    The mapping of the lightning optical pulses detected by the Lightning Imaging Sensor (LIS) is compared with the radiation sources by Lightning Detection and Ranging (LDAR) and the National Lightning Detection Network (NLDN) for three thunderstorms observed during and overpasses on 15 August 1998. The comparison involves 122 flashes including 42 ground and 80 cloud flashes. For ground flash, the LIS recorded the subsequent strokes and changes inside the cloud. For cloud flashes, LIS recorded those with higher sources in altitude and larger number of sources. The discrepancies between the LIS and LDAR flash locations are about 4.3 km for cloud flashes and 12.2 km for ground flashes. The reason for these differences remain a mystery.

    1999-01-01

    The chance of having the TRMM satellite pass over east central Florida when there is lightning over the NASA Kennedy Space Center (KSC) and USAF Eastern Range (ER) is small; however, such a condition did occur on September 21, 1998 (Day 264). Starting at about 20:40 GMT, the Lightning Imaging Sensor (LIS) reported 5 flashes during a 90 second interval that the KSC-ER was within the sensor field of view. Ground-based instrumentation, the Lightning Detection and Ranging (LDAR) system and a network of electric field mills (FM), detected 6 flashes in the same interval. In this paper, we will compare the times and locations of the optical pulses that were detected by LIS with the times and locations of RF sources (LDAR) and the charges that were deposited by the flash (FM network). We will show that LIS responded to all flashes that the LDAR and FM network detected; however, two discharges that were separated by less than 1 second in time and by about 10 km in space were grouped as one flash by the LIS data processing algorithm. In spite of the fact that all flashes occurred near the edge of the LIS field of view, the locations of the LIS events were consistent with both the LDAR and FM locations (the latter are usually within 1-2 kilometers of each other and often are co-located). Two of the 5 flashes reported by LIS were shifted north by about 8 km from the corresponding LDAR and FM locations. The LIS flash times tended to be after the first LDAR pulse was detected and before the last, and the integrated light signal (per LIS event) was surprisingly constant over the 5 flashes that were detected by LIS. In the future, we plan to study more correlated events and will try to determine whether and how the LIS light signal is related to the charge transfer in the flash and/or the number and spatial extent of RF sources.

    The fast, random nature and characteristics of ice hockey make injury prevention a challenge as high-velocity impacts with players, sticks and boards occur and may result in a variety of injuries, including concussion. Five online databases (January 1970 and May 2012) were systematically searched followed by a manual search of retrieved papers. Seventeen studies met the inclusion criteria. The heterogeneous diagnostic procedures and criteria for concussion prevented a pooling of data. When comparing the injury data of European and North American or Canadian leagues, the latter show a higher percentage of concussions in relation to the overall number of injuries (2-7% compared with 5.3-18.6%). The incidence ranged from 0.2/1000 to 6.5/1000 game-hours, 0.72/1000 to 1.81/1000 athlete-exposures and was estimated at 0.1/1000 practice-hours. The included studies indicate a high incidence of concussion in professional and collegiate ice hockey. Despite all efforts there is no conclusive evidence that rule changes or other measures lead to a decrease in the actual incidence of concussions over the last few decades. This review supports the need for standardisation of the diagnostic criteria and reporting protocols for concussion to allow interstudy comparisons in the future.

    2013-05-01

    Approximately 7.6 million high school students in the United States participate in sports. Although most sport-related injuries in adolescents are considered minor emergencies, life-threatening illnesses or injuries may occur, such as sudden cardiac arrest, heat stroke, status asthmaticus and exercise-induced asthma, catastrophic brain injuries, cervical spine injuries, heat- and cold-related illness, blunt chest/abdominal injuries, and extremity fractures resulting in compartment syndrome. Emergency preparedness in athletics involves the identification of and planning for medical services to promote the safety of the athlete, to limit injury, and to provide medical care at the site of practice or competition. Several national organizations have published guidelines for emergency preparedness in school-based athletics. Our article reviews guidelines for emergency preparedness put forth by the Sideline Preparedness collaboration (comprised of 6 major professional associations, including the American Academy of Family Physicians, American Academy of Orthopedic Surgeons, American College of Sports Medicine, American Medical Society for Sports Medicine, American Orthopaedic Society for Sports Medicine, and American Osteopathic Academy of Sports Medicine), the National Athletic Trainers' Association, the American Academy of Pediatrics' Committee on School Health, and the American Heart Association. Additionally, we review published data examining compliance of US high schools with these recommendations for emergency preparedness in school-based athletics, determine deficiencies, and provide recommendations for improvement based on these deficiencies.

  6. Developmental downregulation of LIS1 expression limits axonal extension and allows axon pruning

    Directory of Open Access Journals (Sweden)

    2017-07-01

    Full Text Available The robust axonal growth and regenerative capacities of young neurons decrease substantially with age. This developmental downregulation of axonal growth may facilitate axonal pruning and neural circuit formation but limits functional recovery following nerve damage. While external factors influencing axonal growth have been extensively investigated, relatively little is known about the intrinsic molecular changes underlying the age-dependent reduction in regeneration capacity. We report that developmental downregulation of LIS1 is responsible for the decreased axonal extension capacity of mature dorsal root ganglion (DRG neurons. In contrast, exogenous LIS1 expression or endogenous LIS1 augmentation by calpain inhibition restored axonal extension capacity in mature DRG neurons and facilitated regeneration of the damaged sciatic nerve. The insulator protein CTCF suppressed LIS1 expression in mature DRG neurons, and this reduction resulted in excessive accumulation of phosphoactivated GSK-3β at the axon tip, causing failure of the axonal extension. Conversely, sustained LIS1 expression inhibited developmental axon pruning in the mammillary body. Thus, LIS1 regulation may coordinate the balance between axonal growth and pruning during maturation of neuronal circuits.

    Full Text Available The paper presents a methodology of identifying the insertion site of LIS-1-1 (Linum Insertion Sequence 1 element in flax Albidum variety when growing under the in vitro combined with environmental stress conditions. Abiotic stress was induced by a reduced nutrient content in a growth medium. The LIS-1 insertion site amplification was reaLIS-1ed using the forward LIS-L: 5'-GGG CAG TTT AAC TGT AAC GAA - 3 'and revers LIS-R: 5'-GCT TGG ATT TAG ACT TGG CAA C - 3' primers by PCR. PCR product was sequenced by direct sequencing method to proove the nucleotide sequence for matching with database LIS-1 sequence. A comparison has been matched with the sequence of the amplified segment in the database for all nucleotides except the 11-position in the 5'-3 ' direction, where instead of the three adenine pair is a couple in the Albidum variety. Changes caused by mobile elements or insertion sequences result in common flax in variability that can be used for the purposes of development of effective marker identification or environment based markers development.

    2015-12-01

    Full Text Available This paper describes qualities of a library classification system that are commonly discussed in the LIS tradition and literature, and explains such a system’s three main functions, namely knowledge mapping, information retrieval, and shelf arrangement. In this vein, the paper states the functional requirements of bibliographic classifications, which broadly are subject collocation and facilitation of browsing the collection. It explains with details the components of a library classification system and their functions. The major components are schedules, notations, and index. It also states their distinguished features, such as generalia class, form divisions, book numbers, and devices for number synthesis which are not required in a knowledge classification. It illustrates with examples from the WebDewey good examples of added features of an online library classification system. It emphasizes that institutional backup and a revision machinery are essential for a classification to survive and remain relevant in the print and e-environment.

Fifty-seven references were suitable for analysis. This review was supplemented by a questionnaire survey of learners and an interview study of learning providers to ensure that data identified from the literature were grounded in reality. The main barriers are: requirement for change; costs; poorly designed packages; inadequate technology; lack of skills; need for a component of face-to-face teaching; time intensive nature of e-learning; computer anxiety. A range of solutions can solve these barriers. The main solutions are: standardization; strategies; funding; integration of e-learning into the curriculum; blended teaching; user friendly packages; access to technology; skills training; support; employers paying e-learning costs; dedicated work time for e-learning. The authors argue that librarians can play an important role in e-learning: providing support and support materials; teaching information skills; managing and providing access to online information resources; producing their own e-learning packages; assisting in the development of other packages.

    The objective of this systematic review was to synthesize the available qualitative evidence on the knowledge, attitudes and beliefs of adult patients, healthcare professionals and carers about oral dosage form modification. A systematic review and synthesis of qualitative studies was undertaken, utilising the thematic synthesis approach. The following databases were searched from inception to September 2015: PubMed, Medline (EBSCO), EMBASE, CINAHL, PsycINFO, Web of Science, ProQuest Databases, Scopus, Turning Research Into Practice (TRIP), Cochrane Central Register of Controlled Trials (CENTRAL) and the Cochrane Database of Systematic Reviews (CDSR). Citation tracking and searching the references lists of included studies was also undertaken. Grey literature was searched using the OpenGrey database, internet searching and personal knowledge. An updated search was undertaken in June 2016. Studies meeting the following criteria were eligible for inclusion; (i) used qualitative data collection and analysis methods; (ii) full-text was available in English; (iii) included adult patients who require oral dosage forms to be modified to meet their needs or; (iv) carers or healthcare professionals of patients who require oral dosage forms to be modified. Two reviewers independently appraised the quality of the included studies using the Critical Appraisal Skills Programme Checklist. A thematic synthesis was conducted and analytical themes were generated. Of 5455 records screened, seven studies were eligible for inclusion; three involved healthcare professionals and the remaining four studies involved patients. Four analytical themes emerged from the thematic synthesis: (i) patient-centred individuality and variability; (ii) communication; (iii) knowledge and uncertainty and; (iv) complexity. The variability of individual patient's requirements, poor communication practices and lack of knowledge about oral dosage form modification, when combined with the complex and multi

    Subcortical band heterotopia (SBH) is a neuronal migration disorder. DCX mutations are responsible for almost all familial cases, 80% of sporadic female cases, and 25% of sporadic male cases of SBH, and are associated with more severe gyral and migration abnormality over the anterior brain regions. Somatic mosaicism has previously been hypothesized in a patient with posteriorly predominant SBH and a mutation of the LIS1 gene, which is usually mutated in patients with severe lissencephaly. The authors identified mosaic mutations of LIS1 in two patients (Patients 1 and 2) with predominantly posterior SBH. After ruling out DCX mutations, the authors performed sequencing of the LIS1 gene in lymphocyte DNA. Because sequence peaks in both patients were suggestive of mosaic mutations, they followed up with denaturing high-pressure liquid chromatography analysis on blood and hair root DNA and compared the areas of heteroduplex and homoduplex peaks. A third patient showing the same mutation as Patient 2 but with no evidence of mosaicism was used for comparing the phenotype of mosaic vs full mutation. The two patients with posterior SBH harbored a missense (Arg241Pro) and a nonsense (R8X) mosaic mutation of LIS1. The rate of mosaicism in Patient 1 was 18% in the blood and 21% in the hair roots, whereas in Patient 2 it was 24% and 31% in the same tissues. The patient with a full R8X mutation of LIS1 had severe lissencephaly. Subcortical band heterotopia can occur with mosaic mutations of the LIS1 gene. Mutation analysis of LIS1, using highly sensitive techniques such as denaturing high-pressure liquid chromatography, should be considered for patients with posteriorly predominant subcortical band heterotopia and pachygyria.

    Lissencephaly is a neuronal migration disorder leading to absent or reduced gyration and a broadened but poorly organized cortex. The most common form of lissencephaly is isolated, referred as classic or type 1 lissencephaly. Type 1 lissencephaly is mostly associated with a heterozygous deletion of the entire LIS1 gene, whereas intragenic heterozygous LIS1 mutations or hemizygous DCX mutations in males are less common. Eighteen unrelated patients with type 1 lissencephaly were clinically and genetically assessed. In addition, patients with subcortical band heterotopia (n = 1) or lissencephaly with cerebellar hypoplasia (n = 2) were included. Fourteen new and seven previously described LIS1 mutations were identified. We observed nine truncating mutations (nonsense, n = 2; frameshift, n = 7), six splice site mutations, five missense mutations, and one in-frame deletion. Somatic mosaicism was assumed in three patients with partial subcortical band heterotopia in the occipital-parietal lobes or mild pachygyria. We report three mutations in exon 11, including a frameshift which extends the LIS1 protein, leading to type 1 lissencephaly and illustrating the functional importance of the WD domains at the C terminus. Furthermore, we present two patients with novel LIS1 mutations in exon 10 associated with lissencephaly with cerebellar hypoplasia type a. In contrast to previous reports, our data suggest that neither type nor position of intragenic mutations in the LIS1 gene allows an unambiguous prediction of the phenotypic severity. Furthermore, patients presenting with mild cerebral malformations such as subcortical band heterotopia or cerebellar hypoplasia should be considered for genetic analysis of the LIS1 gene.

    Mutations in the human LIS1 gene cause the smooth brain disease classical lissencephaly. To understand the underlying mechanisms, we conducted in situ live cell imaging analysis of LIS1 function throughout the entire radial migration pathway. In utero electroporation of LIS1 small interference RNA and short hairpin dominant negative LIS1 and dynactin cDNAs caused a dramatic accumulation of multipolar progenitor cells within the subventricular zone of embryonic rat brains. This effect resulted from a complete failure in progression from the multipolar to the migratory bipolar state, as revealed by time-lapse analysis of brain slices. Surprisingly, interkinetic nuclear oscillations in the radial glial progenitors were also abolished, as were cell divisions at the ventricular surface. Those few bipolar cells that reached the intermediate zone also exhibited a complete block in somal translocation, although, remarkably, process extension persisted. Finally, axonal growth also ceased. These results identify multiple distinct and novel roles for LIS1 in nucleokinesis and process dynamics and suggest that nuclear position controls neural progenitor cell division.

    2016-01-01

    Full Text Available The X-ray absorption spectroscopy technique has been applied to study different stages of the lithium/sulfur (Li/S cell life cycle. We have investigated how speciation of S in Li/S cathodes changes upon the introduction of CTAB (cetyltrimethylammonium bromide, CH3(CH215N+(CH33Br− and with charge/discharge cycling. The introduction of CTAB changes the synthesis reaction pathway dramatically due to the interaction of CTAB with the terminal S atoms of the polysulfide ions in the Na2Sx solution. For the cycled Li/S cell, the loss of electrochemically active sulfur and the accumulation of a compact blocking insulating layer of unexpected sulfur reaction products on the cathode surface during the charge/discharge processes make the capacity decay. A modified coin cell and a vacuum-compatible three-electrode electro-chemical cell have been introduced for further in-situ/in-operando studies.

    Recent advances in long-range lightning detection technologies have improved our understanding of thunderstorm evolution in the data sparse oceanic regions. Although the expansion and improvement of long-range lightning datasets have increased their applicability, these applications (e.g., data assimilation, atmospheric chemistry, and aviation weather hazards) require knowledge of the network detection capabilities. Toward this end, the present study evaluates data from the World Wide Lightning Location Network (WWLLN) using observations from the Lightning Imaging Sensor (LIS) aboard the Tropical Rainfall Measurement Mission (TRMM) satellite. The study documents the WWLLN detection efficiency and location accuracy relative to LIS observations, describes the spatial variability in these performance metrics, and documents the characteristics of LIS flashes that are detected by WWLLN. Improved knowledge of the WWLLN detection capabilities will allow researchers, algorithm developers, and operational users to better prepare for the spatial and temporal coverage of the upcoming GOES-R Geostationary Lightning Mapper (GLM).

  19. Classical lissencephaly and double cortex (subcortical band heterotopia): LIS1 and doublecortin.

    Science.gov (United States)

    Gleeson, J G

    2000-04-01

    Classical lissencephaly and double cortex are genetic neuronal migration disorders associated with mental retardation and epilepsy. In classical lissencephaly, the six-layered cortex is replaced by a four layered structure lacking normal gyri or sulci. In double cortex, a second layer of cortical neurons underlies a normal cortex. A mutation in LIS1 or doublecortin can lead to either classical lissencephaly or double cortex, but because LIS1 is autosomal and doublecortin is X-linked (on the X chromosome), the disease inheritance pattern and risk of recurrence for the two genes are distinct. Mutation analysis for LIS1 and doublecortin is essential in determining the etiology of the disease in patients and may be helpful in determining the recurrence risk in families.

  1. Conflicts Between Parents and Health Professionals About a Child's Medical Treatment: Using Clinical Ethics Records to Find Gaps in the Bioethics Literature.

    McDougall, Rosalind; Notini, Lauren; Phillips, Jessica

    2015-09-01

    Clinical ethics records offer bioethics researchers a rich source of cases that clinicians have identified as ethically complex. In this paper, we suggest that clinical ethics records can be used to point to types of cases that lack attention in the current bioethics literature, identifying new areas in need of more detailed bioethical work. We conducted an analysis of the clinical ethics records of one paediatric hospital in Australia, focusing specifically on conflicts between parents and health professionals about a child's medical treatment. We identified, analysed, and compared cases of this type from the clinical ethics records with cases of this type discussed in bioethics journals. While the cases from journals tended to describe situations involving imminent risk to the child's life, a significant proportion of the clinical ethics records cases involved different stakes for the child involved. These included distress, poorer functional outcome, poorer psychosocial outcome, or increased risk of surgical complications. Our analysis suggests that one type of case that warrants more detailed ethics research is parental refusal of recommended treatment, where the refusal does not endanger the child's life but rather some other aspect of the child's well-being.

    Over the past 20 years, the NASA Marshall Space Flight Center, the University of Alabama in Huntsville, and their partners developed and demonstrated the effectiveness and value of space-based lightning observations as a remote sensing tool for Earth science research and applications, and, in the process, established a robust global lightning climatology. The observations included measurements from the Lightning Imaging Sensor (LIS) on the Tropical Rainfall Measuring Mission (TRMM) and its Optical Transient Detector (OTD) predecessor that acquired global observations of total lightning (i.e., intracloud and cloud-to-ground discharges) spanning a period from May 1995 through April 2015. As an exciting follow-on to these prior missions, a space-qualified LIS built as a flight-spare for TRMM will be delivered to the International Space Station (ISS) for a 2 year or longer mission, flown as a hosted payload on the Department of Defense (DoD) Space Test Program-Houston 5 (STP-H5) mission. The STP-H5 payload containing LIS is scheduled launch from NASA's Kennedy Space Center to the ISS in November 2016, aboard the SpaceX Cargo Resupply Services-10 (SpaceX-10) mission, installed in the unpressurized "trunk" of the Dragon spacecraft. After the Dragon is berth to ISS Node 2, the payload will be removed from the trunk and robotically installed in a nadir-viewing location on the external truss of the ISS. Following installation on the ISS, the LIS Operations Team will work with the STP-H5 and ISS Operations Teams to power-on LIS and begin instrument checkout and commissioning. Following successful activation, LIS orbital operations will commence, managed from the newly established LIS Payload Operations Control Center (POCC) located at the National Space Science Technology Center (NSSTC) in Huntsville, AL. The well-established and robust processing, archival, and distribution infrastructure used for TRMM was easily adapted to the ISS mission, assuring that lightning

    Jiwa, Moyez; McManus, Alexandra; Dadich, Ann

    2013-11-01

    Primary health services are well placed to reinforce prevention, early intervention, and connected care. Despite this important role, primary care providers (PCPs) have a limited capacity to meet the varied needs of people with cancer and their carers - furthermore, the reasons for this largely remain unexplored. To identify: (1) the knowledge, attitudes, and beliefs held by health professionals and patients that can influence the engagement of PCPs with the early detection of cancer and follow-up care; (2) evidence that attitudes and beliefs can be modified with measureable impact on the engagement of PCPs with cancer care; and (3) potential targets for intervention. This was achieved through a review of English publications from 2000 onwards, sourced from six academic databases and complemented with a search for grey literature. A total of 4212 articles were reviewed to identify studies conducted in the UK, Canada, Holland (or The Netherlands), Australia, or New Zealand given the comparable role of PCPs. Several factors hinder PCP participation in cancer care, all of which are related to knowledge, attitudes, and beliefs. Patients and specialists are uncertain about the role that primary care could play and whether their primary care team has the necessary expertise. PCPs have varied opinions about the ideal content of follow-up programs. Study limitations include: the absence of well accepted definitions of key terms; the indexing systems used by databases to code publications, which may have obscured all relevant publications; the paucity of robust research; and possible researcher bias which was minimized through independent review by trained reviewers and the implementation of rigorous inter-rater reliability measures. Knowledge, attitudes, and beliefs influence PCP engagement in cancer care. It is important to develop shared understandings of these terms because the knowledge, attitudes, and beliefs of PCPs, specialists, patients, and their families can

    Lithium-sulfur (Li-S) battery is a very promising candidate for the next generation of energy storage systems required for electrical vehicles and grid energy storage applications due to its very high theoretical specific energy (2500 W h kg-1). However, the low coulombic efficiency (CE) during repeated Li plating/stripping of these processes have limited practical application of rechargeable Li-S batteries. In this work, a new electrolyte system based on high concentration of LiNO3 in diglyme solvent is developed which enables high CE of Li metal plating/stripping and high stability of Li anode in the sulfur containing electrolyte. Tailoring of electrolyte properties for the Li negative electrode has proven to be a successful strategy for improving the capacity retention and cycle life of Li-S batteries. This electrolyte provides a CE for Li plating/stripping of greater than 99% for over 200 cycles. In contrast, Li metal cycles for only less than 35 cycles at high CE in the standard 1 M LiTFSI + 2wt% LiNO3 in DOL:DME electrolyte under the same conditions. The stable Li metal anode enabled by the new electrolyte may accelerate the applications of high energy density Li-S batteries in both electrical vehicles and large-scale grid energy storage markets.

    The lithium-sulfur (Li-S) battery is a very promising candidate for the next generation of energy storage systems required for electrical vehicles and grid energy storage applications due to its very high theoretical specific energy (2500 W h kg(-1)). However, low Coulombic efficiency (CE) during repeated Li metal plating/stripping has severely limited the practical application of rechargeable Li-S batteries. In this work, a new electrolyte system based on a high concentration of LiNO3 in diglyme (G2) solvent is developed which enables an exceptionally high CE for Li metal plating/stripping and thus high stability of the Li anode in the sulfur-containing electrolyte. The tailoring of electrolyte properties for the Li anode has proven to be a highly successful strategy for improving the capacity retention and cycle life of Li-S batteries. This electrolyte provides a CE of greater than 99% for over 200 cycles of Li plating/stripping. In contrast, the Li anode cycles for less than 35 cycles (with a high CE) in the state-of-the-art 1 M LiTFSI + 0.3 M LiNO3 in 1,3-dioxolane: 1,2-dimethoxyethane (DOL:DME) electrolyte under the same conditions. The stable Li anode enabled by the new electrolyte may accelerate the applications of high energy density Li-S batteries in both electrical vehicles and large-scale grid energy storage markets.

    Full Text Available The present paper discussed results of a study which aimed to explore the knowledge and use of Web 2.0 technologies by LIS academics in Iran and to explore the challenges they faced for using these technologies. The research method was explorative and empirical. Data was collected through a web-based survey questionnaire containing both open and close ended questions. The results showed that LIS academics in Iran had good level of familiarity with some Web 2.0 tools such as blog, wiki, YouTube and Facebook. However, their familiarity with some other Web 2.0 tools such as RSS, feeds, Twitter, Flickr, Delicious and podcast was limited. Blog, discussion groups, chat tools, file sharing tools, Wikis, SMS, video sharing tools and forum were used respectively by LIS academics in their teaching. Internet filtering was identified as the most inhibiting barrier to the use of Web 2.0 tools. Lack of access to high speed internet and lack of training were pointed as the other identified barriers. Authors suggested that to reap the benefits of Web 2.0, LIS academics needed to find alternative non filtered Web 2.0 tools to employ in their teaching and research.

    2015-01-01

    This paper is a critical reconstruction of Luciano Floridi's view of librarianship as "stewardship of a semantic environment," a view that is at odds with the dominant tradition in which library and information science (LIS) is understood as social epistemology. Floridi's work helps to explain the normative dimensions of librarianship in…

  20. Timescales for determining temperature and dissolved oxygen trends in the Long Island Sound (LIS) estuary

    Staniec, Allison; Vlahos, Penny

    Long-term time series represent a critical part of the oceanographic community's efforts to discern natural and anthropogenically forced variations in the environment. They provide regular measurements of climate relevant indicators including temperature, oxygen concentrations, and salinity. When evaluating time series, it is essential to isolate long-term trends from autocorrelation in data and noise due to natural variability. Herein we apply a statistical approach, well-established in atmospheric time series, to key parameters in the U.S. east coast's Long Island Sound estuary (LIS). Analysis shows that the LIS time series (established in the early 1990s) is sufficiently long to detect significant trends in physical-chemical parameters including temperature (T) and dissolved oxygen (DO). Over the last two decades, overall (combined surface and deep) LIS T has increased at an average rate of 0.08 ± 0.03 °C yr-1 while overall DO has dropped at an average rate of 0.03 ± 0.01 mg L-1yr-1 since 1994 at the 95% confidence level. This trend is notably faster than the global open ocean T trend (0.01 °C yr-1), as might be expected for a shallower estuarine system. T and DO trends were always significant for the existing time series using four month data increments. Rates of change of DO and T in LIS are strongly correlated and the rate of decrease of DO concentrations is consistent with the expected reduced solubility of DO at these higher temperatures. Thus, changes in T alone, across decadal timescales can account for between 33 and 100% of the observed decrease in DO. This has significant implications for other dissolved gases and the long-term management of LIS hypoxia.

  1. Association of Lis1 with outer arm dynein is modulated in response to alterations in flagellar motility

    2012-01-01

    The cytoplasmic dynein regulatory factor Lis1, which induces a persistent tight binding to microtubules and allows for transport of cargoes under high-load conditions, is also present in motile cilia/flagella. We observed that Lis1 levels in flagella of Chlamydomonas strains that exhibit defective motility due to mutation of various axonemal substructures were greatly enhanced compared with wild type; this increase was absolutely dependent on the presence within the flagellum of the outer arm dynein α heavy chain/light chain 5 thioredoxin unit. To assess whether cells might interpret defective motility as a “high-load environment,” we reduced the flagellar beat frequency of wild-type cells through enhanced viscous load and by reductive stress; both treatments resulted in increased levels of flagellar Lis1, which altered the intrinsic beat frequency of the trans flagellum. Differential extraction of Lis1 from wild-type and mutant axonemes suggests that the affinity of outer arm dynein for Lis1 is directly modulated. In cytoplasm, Lis1 localized to two punctate structures, one of which was located near the base of the flagella. These data reveal that the cell actively monitors motility and dynamically modulates flagellar levels of the dynein regulatory factor Lis1 in response to imposed alterations in beat parameters.

  2. On the Nature of Large-Radiance Flashes Reported by LIS over the U.S.

    2016-12-01

    A total of 372,510 flashes detected by the Lighting Imaging Sensor (LIS) during three months (June-August in 2013) have been examined, 38,179 of which occurred in the coverage area of the U.S. National Lightning Detection Network (NLDN). The flash optical radiance observed by LIS has a large uncertainty and variability due to both the complex nature of lightning channels that varies with flash type, and the multi-scattering of the clouds. The daytime and nighttime flashes detected by LIS in the NLDN coverage region exhibited a median radiance of 5.66×10^6 and 1.18×10^6 uJ m-1 ster-1 um-1, respectively. Daytime (Nighttime) flash radiance varied over 4 orders of magnitude, between 4,274 (4,158) and 3.96×10^7 (5.68×10^7) uJ m-1 ster-1 um-1. In this work-in-progress we explore the variability of the 441 extreme-radiance (top 10%) flashes, through spatial and temporal correlation with NLDN-reported cloud pulses and cloud-to-ground (CG) strokes. Initial findings suggest that many of these flashes are associated with either hybrid flashes (intra-cloud flash followed by CG strokes determined by the NLDN report) or high current CG flashes. We have explored a subset of cases which had both extremely large flash footprint (size of the flash in km^2) and optical radiance, as well as a relatively small number of LIS groups in the flash. These large flash footprints were due to large numbers of simultaneous LIS events that occurred during a small number of 2 ms LIS event observation periods, suggesting that the flash characteristics were dominated by a single energetic discharge. Our presentation will expand upon these findings, including an assessment of the spatial distribution of event radiance within groups as a function of group size and flash type.

    1987-12-01

    Full Text Available The origin and early meaning of Latin exīlis-e have not yet received a convincing explanation. It is suggested in this paper that in exīlis-e —owing to the fact that the traditional view which relates it with exiguus can hardly be accepted— it is possible to recognize an ancient rural and augural word *ekssu̯(eidslis, strongly related with lat. sidus, ‘star’, resulting of the IE root *su̯(eid-, ‘shine, blaze’. The laicization of its early meaning ‘away from the star’s fortune’ i.e. ‘being out of luck’ would have caused a semantic transfer to ‘weak, thin, little’. Many Latin and romance parallel cases prove the possibility of this hypothesis.

    Lithium sulfur (Li-S) redox flow battery (RFB) is a promising candidate for high energy large-scale energy storage application due to good solubility of long-chain polysulfide species and low cost of sulfur. In this report, recent progress and new concepts for Li-S redox flow batteries are discussed with an emphasis on the fundamental understanding and control of lithium polysulfide chemistry to enable the development of liquid phase Li-S redox flow prototype cells. These differ significantly from conventional static Li-S batteries targeting for vehicle electrification. A high solubility of the different lithium polysulfides generated at different depths of discharge and states of charge is required for a flow battery in order to take full advantage of the multiple electron transitions between elemental sulfur and Li2S. A new DMSO-based electrolyte is proposed for Li-S redox flow batteries, which not only enables the high solubility of lithium polysulfide species, especially for the short-chain species, but also results in excellent cycling with a high Coulombic efficiency. The challenges and opportunities for the Li-S redox flow concept have also been discussed in depth.

  15. Dynein, Lis1 and CLIP-170 counteract Eg5-dependent centrosome separation during bipolar spindle assembly

    2008-01-01

    Bipolar spindle assembly critically depends on the microtubule plus-end-directed motor Eg5 that binds antiparallel microtubules and slides them in opposite directions. As such, Eg5 can produce the necessary outward force within the spindle that drives centrosome separation and inhibition of this antiparallel sliding activity results in the formation of monopolar spindles. Here, we show that upon depletion of the minus-end-directed motor dynein, or the dynein-binding protein Lis1, bipolar spindles can form in human cells with substantially less Eg5 activity, suggesting that dynein and Lis1 produce an inward force that counteracts the Eg5-dependent outward force. Interestingly, we also observe restoration of spindle bipolarity upon depletion of the microtubule plus-end-tracking protein CLIP-170. This function of CLIP-170 in spindle bipolarity seems to be mediated through its interaction with dynein, as loss of CLIP-115, a highly homologous protein that lacks the dynein–dynactin interaction domain, does not restore spindle bipolarity. Taken together, these results suggest that complexes of dynein, Lis1 and CLIP-170 crosslink and slide microtubules within the spindle, thereby producing an inward force that pulls centrosomes together.

    Given the importance of the atmospheric aerosol, the number of instruments and measurement networks which focus on its characterization are growing. Many challenges are derived from standardization of protocols, monitoring of the instrument status to evaluate the network data quality and manipulation and distribution of large volume of data (raw and processed). CÆLIS is a software system which aims at simplifying the management of a network, providing tools by monitoring the instruments, processing the data in real time and offering the scientific community a new tool to work with the data. Since 2008 CÆLIS has been successfully applied to the photometer calibration facility managed by the University of Valladolid, Spain, in the framework of Aerosol Robotic Network (AERONET). Thanks to the use of advanced tools, this facility has been able to analyze a growing number of stations and data in real time, which greatly benefits the network management and data quality control. The present work describes the system architecture of CÆLIS and some examples of applications and data processing.

    Li-ion batteries have transformed portable electronics and will play a key role in the electrification of transport. However, the highest energy storage possible for Li-ion batteries is insufficient for the long-term needs of society, for example, extended-range electric vehicles. To go beyond the horizon of Li-ion batteries is a formidable challenge; there are few options. Here we consider two: Li-air (O(2)) and Li-S. The energy that can be stored in Li-air (based on aqueous or non-aqueous electrolytes) and Li-S cells is compared with Li-ion; the operation of the cells is discussed, as are the significant hurdles that will have to be overcome if such batteries are to succeed. Fundamental scientific advances in understanding the reactions occurring in the cells as well as new materials are key to overcoming these obstacles. The potential benefits of Li-air and Li-S justify the continued research effort that will be needed.

    With the exponential growth of technology in mobile devices and the rapid expansion of electric vehicles into the market, it appears that the energy density of the state-of-the-art Li-ion batteries (LIBs) cannot satisfy the practical requirements. Sulfur has been one of the best cathode material choices due to its high charge storage (1675 mAh g-1), natural abundance and easy accessibility. In this paper, calculations are performed for different cell design parameters such as the active material loading, the amount/thickness of electrolyte, the sulfur utilization, etc. to predict the energy density of Li-S cells based on liquid, polymeric and ceramic electrolytes. It demonstrates that Li-S battery is most likely to be competitive in gravimetric energy density, but not volumetric energy density, with current technology, when comparing with LIBs. Furthermore, the cells with polymer and thin ceramic electrolytes show promising potential in terms of high gravimetric energy density, especially the cells with the polymer electrolyte. This estimation study of Li-S energy density can be used as a good guidance for controlling the key design parameters in order to get desirable energy density at cell-level.

    The experience of being a carer of a person with dementia at the end of life is expressed in these 12 accounts. This is a synthesis of the concerns and challenges for carers at the end of life. These accounts are often insightful and provide several views of carers' and professionals' experience. Having a close relationship as a carer gives a unique and poignant view. What emerges from this review is a range of perspectives that provide contrasting views of the heterogeneity of carers and professionals. This may be helpful for professionals and policy makers to consider when planning end-of-life care strategies for people with dementia and insights drawn from hearing directly from carers may be powerful learning tools.

    The Cydnidae (Hemiptera: Heteroptera: Pentatomoidea) is a true bug family with almost 700 species distributed worldwide (Lis 1996, 1999, 2006). These bugs usually dig in the ground (e.g., sand, soil, litter) and, therefore, are commonly known as the burrower bugs or burrowing bugs. Digging in the ground is possible because of several morphological adaptations, including well-developed tibial combs (Lis and Schaefer 2005), coxal combs (Lis 2010), and strong hair-like and peg-like setae on the head margins in larval and adult stages (Lis and Pluot-Sigwalt 2002) (see: Fig. 1A).

    Yan, A.; West, J.

    2016-12-01

    The validity of Geosciences research is of great significance to general public and policy-makers. In an earlier study, we surveyed 136 faculty and graduate students in geosciences. The result indicated that nearly 80% of respondents who had ever reproduced a published study had failed at least one time in reproducing, suggesting a general lack of research reproducibility in geosciences. Although there is much enthusiasm for creation of technologies such as workflow system, literate programming, and cloud-based system to facilitate reproducibility, much less emphasis has been placed on the information services essential for meaningful use of these tools. Library and Information Science (LIS) has a rich tradition of providing customized service for research communities. LIS professionals such as academic librarians have made strong contribution to resources locating, software recommending, data curation, metadata guidance, project management, submission review and author training. In particular, university libraries have been actively developing tools and offering guidelines, consultations, and trainings on Data Management Plan (DMP) required by National Science Foundation (NSF). And effective data management is a significant first step towards reproducible research. Hereby we argue that LIS professionals may be well-positioned to assist researchers to make their research reproducible. In this study, we aim to answer the question: how can LIS professionals assist geoscience researchers in making their research capable of being reproduced? We first synthesize different definitions of "reproducibility" and provide a conceptual framework of "reproducibility" in geosciences to resolve some of the misunderstandings around related terminology. Using a case study approach, we then examine 1) university librarians' technical skills, domain knowledge, professional activities, together with their awareness of, readiness for, and attitudes towards research reproducibility and

    Lithium sulfur (Li-S) batteries are considered as promising energy storage systems for the next generation of batteries due to their high theoretical energy densities and low cost. Much effort has been made to improve the practical energy densities and cycling stability of Li-S batteries via diverse designs of materials nanostructure. However, achieving simultaneously good rate capabilities and stable cycling of Li-S batteries is still challenging. Herein, we propose a strategy to utilize a dual effect of metal carbide nanoparticles decorated on carbon nanofibers (MC NPs-CNFs) to realize high rate performance, low hysteresis, and long cycling stability of Li-S batteries in one system. The adsorption experiments of lithium polysulfides (LiPS) to MC NPs and corresponding theoretical calculations demonstrate that LiPS are likely to be adsorbed and diffused on the surface of MC NPs because of their moderate chemical bonding. MC NPs turn out to have also an electrocatalytic role and accelerate electrochemical redox reactions of LiPS, as proven by cyclic voltammetry analysis. The fabricated Li-S batteries based on the W2C NPs-CNFs hybrid electrodes display not only high specific capacity of 1200 mAh/g at 0.2C but also excellent rate performance and cycling stability, for example, a model setup can be operated at 1C for 500 cycles maintaining a final specific capacity of 605 mAh/g with a degradation rate as low as 0.06%/cycle.

    The synergistic design of cathode region was conducted to minimize the shuttle effect of polysulfides and decrease the loading of inactive components in order to acquire high-energy-density lithium-sulfur (Li-S) batteries. The well-designed cathode region presented two special characteristics: one was the intertwined nanofibers interlayer based on ultrafine TiO2 nanocrystal uniformly embedded within N-doping porous carbon; the other was the lightweight and three-dimensional current collector of fibrous cellulose paper coated by reduced graphene oxide. In consequence, the decent reversible capacity of 874.8 mA h g-1 was acquired at 0.1 C with a capacity retention of 91.83% after 100 cycles. Besides, the satisfactory capacity of 670 mA h g-1 was delivered after 300 cycles at 1 C with the small decay rate of only 0.08%. Because of higher capacity and lower loading of inactive component in cathode region, the energy density of cell increased more than five times compared with unmodified cell. Moreover, to further enhance the energy density, the high-sulfur-loading electrode was fabricated. A good areal capacity of 4.27 mA h cm-2 was retained for the cell with the active material of 4 mg cm-2 and the cycle stability was also well-maintained. In addition, due to the flexibility of interlayer and current collector, Li-S full cell (in pouch cell format) was easily curved. Therefore, the synergistic design for cathode region, which combines the flexible and mass-produced interlayer and current collector together, provides an effective access to Li-S batteries with high energy density and flexibility for practical application.

    Gridded climatologies of total lightning flash rates observed by the spaceborne Optical Transient Detector (OTD) and Lightning Imaging Sensor (LIS) instruments have been updated. OTD collected data from May 1995 to March 2000. LIS data (equatorward of about 38°) adds the years 1998-2010. Flash counts from each instrument are scaled by the best available estimates of detection efficiency. The long LIS record makes the merged climatology most robust in the tropics and subtropics, while the high latitude data is entirely from OTD. The gridded climatologies include annual mean flash rate on a 0.5° grid, mean diurnal cycle of flash rate on a 2.5° grid with 24 hour resolution, mean annual cycle of flash rate on a 0.5° or 2.5° grid with daily, monthly, or seasonal resolution, mean annual cycle of the diurnal cycle on a 2.5° grid with two hour resolution for each day, and time series of flash rate over the sixteen year record with roughly three-month smoothing. For some of these (e.g., annual cycle of the diurnal cycle), more smoothing is necessary for results to be robust. The mean global flash rate from the merged climatology is 46 flashes s- 1. This varies from around 35 flashes s- 1 in February (austral summer) to 60 flashes s- 1 in August (boreal summer). The peak annual flash rate at 0.5° scale is 160 fl km- 2 yr- 1 in eastern Congo. The peak monthly average flash rate at 2.5° scale is 18 fl km- 2 mo- 1 from early April to early May in the Brahmaputra Valley of far eastern India. Lightning decreases in this region during the monsoon season, but increases further north and west. An August peak in northern Pakistan also exceeds any monthly averages from Africa, despite central Africa having the greatest yearly average.

    This article reports aspects of a systematic literature review commissioned by the UK Council of Deans of Health. The review collated and analysed UK and international literature on pre-registration healthcare students raising concerns with poor quality care. The research found in that review is summarised here. To review research on healthcare students raising concerns with regard to the quality of practice published from 2009 to the present. In addition to grey literature and Google Scholar a search was completed of the CINAHL, Medline, ERIC, BEI, ASSIA, PsychInfo, British Nursing Index, Education Research Complete databases. Sandelowski and Barroso's (2007) method of metasynthesis was used to screen and analyse the research literature. The review covered students from nursing, midwifery, health visiting, paramedic science, operating department practice, physiotherapy, chiropody, podiatry, speech and language therapy, orthoptist, occupational therapy, orthotist, prosthetist, radiography, dietitian, and music and art therapy. Twenty three research studies were analysed. Most of the research relates to nursing students with physiotherapy being the next most studied group. Students often express a desire to report concerns, but factors such as the potential negative impact on assessment of their practice hinders reporting. There was a lack of evidence on how, when and to whom students should report. The most commonly used research approach found utilised vignettes asking students to anticipate how they would report. Raising a concern with the quality of practice carries an emotional burden for the student as it may lead to sanctions from staff. Further research is required into the experiences of students to further understand the mechanisms that would enhance reporting and support them in the reporting process. Crown Copyright © 2017.

    The polysulfide shuttle effect and lithium dendrite growth in lithium-sulfur (Li-S) batteries can repeatedly breach the anodic solid electrolyte interphase (SEI) over cycling. As a result, irreversible short-chain sulfide side products (Li2Sx, x = 1, 2) keep depositing on the Li anode, leading to the active material loss, increasing the Li+ transport resistance, and thereby reducing the cycle life. In this work, indium iodide (InI3) is investigated as a bifunctional electrolyte additive for Li-S batteries to protect the Li anode and decompose the side products spontaneously. On the one hand, Indium (In) is electrodeposited onto the Li anode prior to Li plating during the initial charging process, forming a chemically and mechanically stable SEI to prevent the Li anode from reacting with soluble polysulfide species to form Li2Sx (x = 1, 2) side products. On the other hand, by adequately overcharging the battery, the triiodide/iodide redox mediator is capable of chemically transforming side products deposited on the Li anode and separator into soluble polysulfides, which can be recycled by the cathode. It is shown that the battery with the InI3 additive exhibits a prolonged cycle life, and is capable of retrieving its capacity by a facile overcharging process.

    Cytoplasmic dynein is the major microtubule minus-end–directed cellular motor. Most dynein activities require dynactin, but the mechanisms regulating cargo-dependent dynein–dynactin interaction are poorly understood. In this study, we focus on dynein–dynactin recruitment to cargo by the conserved motor adaptor Bicaudal D2 (BICD2). We show that dynein and dynactin depend on each other for BICD2-mediated targeting to cargo and that BICD2 N-terminus (BICD2-N) strongly promotes stable interaction between dynein and dynactin both in vitro and in vivo. Direct visualization of dynein in live cells indicates that by itself the triple BICD2-N–dynein–dynactin complex is unable to interact with either cargo or microtubules. However, tethering of BICD2-N to different membranes promotes their microtubule minus-end–directed motility. We further show that LIS1 is required for dynein-mediated transport induced by membrane tethering of BICD2-N and that LIS1 contributes to dynein accumulation at microtubule plus ends and BICD2-positive cellular structures. Our results demonstrate that dynein recruitment to cargo requires concerted action of multiple dynein cofactors. PMID:22956769

    Polysulfide solubility in the electrolyte has a critical role to the Li-S battery but the mechanism study on the solubility needs to be carefully carried out. In this paper we found that lithium 2-trifluoromethyl-4,5-dicyanoimidazole (LiTDI) reveals a suppression of the polysulfide solubility in electrolytes (relative to the most widely used electrolyte formulation) and the Li-S cells achieved homogeneous stable capacity retention upon extensive cycling and Li metal deposition on the anode. Combined experimental, simulation and calculation methods suggest the dominate disproportionation product of Li2S8 is Li2S4 in the LiTDI electrolyte due to a different interaction between lithium ion and TDI anion. The Li2S4 would continuesly form a Li4S8 dimer and be fully locallized to precipitate out. The use of the electrolyte with the LiTDI salt (with polysulfide and LiNO3 additives) enabled a cell with a high sulfur (3 mg-S cm-2) loading to deliver a 1.67 mAh cm-2 areal capacity after 300 stable cycles at a high current (2.4 mA cm-2) density.

    The spectrum of lissencephaly ranges from absent (agyria) or decreased (pachygyria) convolutions to less severe malformation known as subcortical band heterotopia. Mutations involving LIS1 and TUBA1A result in the classic form of lissencephaly, whereas mutations of the DCX gene cause lissencephaly in males and subcortical band heterotopia in females. This report describes the clinical manifestations and imaging and genetic findings in 2 boys with lissencephaly and a girl with subcortical band heterotopia. An ovel mutation (c.83_84delAT, p.Tyr28Phefs*31) was identified in LIS1 in 1 of the boys with lissencephaly and another novel mutation (c.200delG, p.Ile68Leufs*87) was found in DCX in the girl with subcortical band heterotopia. The mutations appeared in the first half of the genes and are predicted to result in truncated proteins. A mutation was found in the TUBA1A gene (c.1205G>A, p.Arg402His) in the other boy. This mutation affects the folding of tubulin heterodimers, changing the interactions with proteins that bind microtubules.

    Full Text Available Proper lamination of the cerebral cortex requires the orchestrated motility of neurons from their place of birth to their final destination. Improper neuronal migration may result in a wide range of diseases, including brain malformations, such as lissencephaly, mental retardation, schizophrenia, and autism. Ours and other studies have implicated that microtubules and microtubule-associated proteins play an important role in the regulation of neuronal polarization and neuronal migration. Here, we will review normal processes of brain development and neuronal migration, describe neuronal migration diseases, and will focus on the microtubule-associated functions of LIS1 and DCX, which participate in the regulation of neuronal migration and are involved in the human developmental brain disease, lissencephaly.

    Stabilizing the polysulfide shuttle while ensuring high sulfur loading holds the key to realizing high theoretical energy of lithium-sulfur (Li-S) batteries. Herein, we present an electrocatalysis approach to demonstrate preferential adsorption of a soluble polysulfide species, formed during discharge process, toward the catalyst anchored sites of graphene and their efficient transformation to long-chain polysulfides in the subsequent redox process. Uniform dispersion of catalyst nanoparticles on graphene layers has shown a 40% enhancement in the specific capacity over pristine graphene and stability over 100 cycles with a Coulombic efficiency of 99.3% at a current rate of 0.2 C. Interaction between electrocatalyst and polysulfides has been evaluated by conducting X-ray photoelectron spectroscopy and electron microscopy studies at various electrochemical conditions.

    Efficient and stable operation of a lithium metal anode has become the enabling factor for next-generation high energy density storage system. Here, vertical graphene (VG) arrays are used as the scaffold structure for high performance Li metal batteries. The melt infusion method is employed to encapsulate Li inside the VG scaffold structure, and the lithiophilic Si layer is coated onto the array surface by magnetron sputtering to assist this melt-infusion process. The porous scaffold structure can control the volume expansion and inhibit the formation of dendritic lithium significantly, leading to the excellent electrochemical performance of the Li composite anode. In addition, the Li-S full batteries with the composite anode display enhanced cycling reversibility.

    Here we report on a Li-S battery with cathode, based on a S powder obtained from bulk amorphous S, by cryogenic grinding. The cathode was prepared from a slurry, wherein the content of cryo-ground S powder was equal to 80 wt % (corresponds to ≈ 2.26 mg cm-2). Other slurry components included carbon Super P, and polyvinylidene fluoride, dispersed in N-methylpyrrolidone. The electrochemical performance of the as-prepared battery was compared to a battery based on an identically prepared paste, but containing reference S powder (with the orthorhombic structure). A longer life cycle, and enhanced capacity per gram, as well as per cm2 of electrode was revealed for the cryo-ground S-based cathode. The electrochemical results show that the loss in capacity of the cryo-ground S powder cathode was just 3% after 50 cycles, which suggests on a higher stability of S inside the cathode during cycling.

    The U.S. Bureau of Reclamation identified the remote sensing of evapotranspiration (ET) as an important water flux for study and designated a test site in the Lower Colorado River basin. A consortium of groups will work together with the goal to develop more accurate and cost effective techniques using the enhanced spatial and temporal coverage afforded by remote sensing. ET is a critical water loss flux where improved estimation should lead to better management of Reclamation responsibilities. There are several areas where NASA satellite and modeling data may be useful to meet Reclamation's objectives for improved ET estimation. In this paper we outline one possible contribution to use NASA's data integration capability of the Land Information System (LIS) to provide a merger of observational (in situ and satellite) with physical process models to provide estimates of ET and other water availability outputs (e.g., runoff, soil moisture) retrospectively, in near real-time, and also providing short-term predictions.

    weather research and forecasting ===== The NASA Short-term Prediction Research and Transition (SPoRT) program has numerous modeling and data assimilation (DA) activities in which the WRF model is a key component. SPoRT generates realtime, research satellite products from the MODIS and VIIRS instruments, making the data available to NOAA/NWS partners running the WRF/EMS, including: (1) 2-km northwestern-hemispheric SST composite, (2) daily, MODIS green vegetation fraction (GVF) over CONUS, and (3) NASA Land Information System (LIS) runs of the Noah LSM over the southeastern CONUS. Each of these datasets have been utilized by specific SPoRT partners in local EMS model runs, with select offices evaluating the impacts using a set of automated scripts developed by SPoRT that manage data acquisition and run the NCAR Model Evaluation Tools verification package. SPoRT is engaged in DA research with the Gridpoint Statistical Interpolation (GSI) and Ensemble Kalman Filter in LIS for soil moisture DA. Ongoing DA projects using GSI include comparing the impacts of assimilating Atmospheric Infrared Sounder (AIRS) radiances versus retrieved profiles, and an analysis of extra-tropical cyclones with intense non-convective winds. As part of its Early Adopter activities for the NASA Soil Moisture Active Passive (SMAP) mission, SPoRT is conducting bias correction and soil moisture DA within LIS to improve simulations using the NASA Unified-WRF (NU-WRF) for both the European Space Agency's Soil Moisture Ocean Salinity and upcoming SMAP mission data. SPoRT has also incorporated real-time global GVF data into LIS and WRF from the VIIRS product being developed by NOAA/NESDIS. This poster will highlight the research and transition activities SPoRT conducts using WRF, NU-WRF, EMS, LIS, and GSI.

    Using NASA's TRMM Lightning Imaging Sensor (LIS) data from 1998 to 2014, this paper presents a 17-year lightning climatology of Bangladesh, at 0.5° × 0.5° spatial resolution. Diurnal, seasonal, monthly and annual variations in the occurrence of lightning flashes were explored. The diurnal regime of lightning is dominated by afternoon/evening events. Overall, peak lightning activity occurs in the early morning (0200 LST) and evening (1900 LST). The distribution of lightning flash counts by season over Bangladesh landmass is as follows: pre-monsoon (69.2%), monsoon (24.1%), post-monsoon (4.6%) and winter (2.1%). Flash rate density (FRD) hotspots were primarily located in the north and north-eastern parts of Bangladesh, with a maximum of 72 fl km-2 year-1. Spatially, the distribution of FRD increases from the Bay of Bengal in the south to relatively higher elevations (of the Himalayan foothills) in the north. A spatial shift in FRD hotspots occurs with change in season. For example, in monsoon season, hotspots of lightning activity move in a south-westerly direction from their pre-monsoon location (i.e. north-eastern Bangladesh) towards West Bengal in India. South and south-eastern parts of Bangladesh experience high lightning activity during post-monsoon season due to regional orographic lifting and low-pressure systems (i.e. cyclone) in the Bay of Bengal. To the best of our knowledge, this is the first study focused on LIS-based lightning climatology over Bangladesh. This baseline study, therefore, is an essential first step towards effective management of lightning-related hazards in Bangladesh.

    muscle overload, nerve compressions, and occupational focal dystonias. This group of disorders in musicians is not included in the Spanish Index of Occupational Diseases to this day. Aim: to review the available scientific literature on musculoskeletal disorders in professional musicians, arising from their professional activity. Methods and materials: a bibliographical review of the scientific literature published in the period 2006-2012 is undertaken. MEDLINE, OSH UPDATE, IBECS, the Cochrane Library, Scielo, LILACS, and CISDOC databases were consulted. Results: 24 articles were selected: an experimental study, two systematic reviews, four case-control studies, 16 cross-section studies and one series of cases study. Prevalence rates ranging 25,5%-86% for musculoskeletal disorders were found, with no consensus on risk factors. Main affected body parts were neck, back and arms. Women were more frequently affected, except for focal dystonias, which were more prevalent in men. Conclusions: musculoskeletal disorders are very prevalent among professional musicians. Further research is needed on this area, and there is a need to put a stress on implementation of preventative measures from the very early stages of the development of these disorders. A point of discussion for the inclusion of these disorders in musicians within the Spanish Index of Professional Disorders should be encouraged.

Furthermore, as patients with LIS can feel pain, despite being unable to move, local block or general anesthesia should be provided for sharp surgical debridement and other painful procedures. This use of the BIS has shown that as a general rule, the staff should treat the patient as though he might be awake and sensate even if he does not open his eyes or move his limbs. Our goal was to continuously monitor pain level and communicate these findings to the entire wound team, ie anesthesiologists, surgeons, and nurses. PMID:25252146

    Subcortical band heterotopia (SBH) are bilateral and symmetric ribbons of gray matter found in the central white matter between the cortex and the ventricular surface, which comprises the less severe end of the lissencephaly (agyria-pachygyria-band) spectrum of malformations. Mutations in DCX (also known as XLIS ) have previously been described in females with SBH. We have now identified mutations in either the DCX or LIS1 gene in three of 11 boys studied, demonstrating for the first time that mutations of either DCX or LIS1 can cause SBH or mixed pachygyria-SBH (PCH-SBH) in males. All three changes detected are missense mutations, predicted to be of germline origin. They include a missense mutation in exon 4 of DCX in a boy with PCH-SBH (R78H), a different missense mutation in exon 4 of DCX in a boy with mild SBH and in his mildly affected mother (R89G) and a missense mutation in exon 6 of LIS1 in a boy with SBH (S169P). The missense mutations probably account for the less severe brain malformations, although other patients with missense mutations in the same exons have had diffuse lissencephaly. Therefore, it appears likely that the effect of the specific amino acid change on the protein determines the severity of the phenotype, with some mutations enabling residual protein function and allowing normal migration in a larger proportion of neurons. However, we expect that somatic mosaic mutations of both LIS1 and DCX will also prove to be an important mechanism in causing SBH in males.

    Full Text Available El artículo plantea un recorrido por algunas perspectivas historiográficas que han mar-cado los estudios de la pólis griega durante las últimas décadas, deteniéndose particu-larmente en el concepto de ciudad consumidora propulsado por Moses Finley, siguiendo a Werner Sombart y Max Weber, y las críticas elaboradas por Mogens Hansen respecto de esta noción en el marco del Copenhagen Polis Centre. Una revisión de la formulación de Sombart sobre la ciudad de consumo –que es el punto de partida de Weber retomado por Finley al proponer que la ciudad antigua era una ciudad de consumidores– le permite a Hansen conjeturar que la pólis no encaja en este modelo, en tanto en cuanto se basa en una distribución de la población entre el campo y la ciudad que no se condice con lo que las recientes prospecciones arqueológicas han comprobado en relación con la pólis. En función de esto, se retoman la noción de “pólis normal”, promovida por John Bintliff pero enunciada originalmente por Eberhard Ruschenbusch, y ciertas ideas de Aristóteles, sobre la población campesina y su inserción en la politeía, para dar cuenta de las relaciones entre población, territorio y modelos políticos que probablemente ca-racterizaron la estructura de la mayoría de las póleis.

    The practical implementation of Li-S technology has been hindered by short cycle life and poor rate capability owing to deleterious effects resulting from the varied solubilities of different Li polysulfide redox products. Here, we report the preparation and utilization of composites with a sulfur-rich matrix and molybdenum disulfide (MoS2) particulate inclusions as Li-S cathode materials with the capability to mitigate the dissolution of the Li polysulfide redox products via the MoS2 inclusions acting as "polysulfide anchors". In situ composite formation was completed via a facile, one-pot method with commercially available starting materials. The composites were afforded by first dispersing MoS2 directly in liquid elemental sulfur (S8) with sequential polymerization of the sulfur phase via thermal ring opening polymerization or copolymerization via inverse vulcanization. For the practical utility of this system to be highlighted, it was demonstrated that the composite formation methodology was amenable to larger scale processes with composites easily prepared in 100 g batches. Cathodes fabricated with the high sulfur content composites as the active material afforded Li-S cells that exhibited extended cycle lifetimes of up to 1000 cycles with low capacity decay (0.07% per cycle) and demonstrated exceptional rate capability with the delivery of reversible capacity up to 500 mAh/g at 5 C.

Journal of Librarianship and Scholarly Communication, 1(4. http://dx.doi.org/10.7710/2162-3309.1086 Abstract Objective – To understand the prevalence of, motivations for, and satisfaction with using a rolling-volume publishing model, as opposed to publishing discrete issues, across open access academic journals in library and information science. Design – A 12 question survey questionnaire. Setting – English-language, open access library and information science (LIS journals published in the United States of America. Subjects – A total of 21 open access LIS journals identified via the Directory of Open Access Journals that were actively publishing, and that also met the authors’ standard of scholarliness, which they established by identifying a journal’s peer-review process or other evidence of rigorous review. Based on responses, 12 journals published using discrete issues, while 9 published as rolling volumes or as rolling volumes with some discrete issues. Methods – In late 2011, the study’s authors invited lead editors or primary journal contacts to complete the survey. Survey participants were asked to identify whether their journal published in discrete issues, rolling volumes, or rolling volumes with occasional discrete issues, with the latter two categories combined as one for ease of results analysis. Survey logic split respondents into two groups, either discrete-issue or rolling-volume. Respondents in both categories were posed similar sets of questions, with the key difference being that the questions directed at each category accounted for the publication model the journals themselves identified as using. Editors from both groups were asked about the reasons for using the publication model they identified for their journal: within the survey tool, authors

  10. Interfacial Reaction Dependent Performance of Hollow Carbon NanoSphere – Sulfur composite as a cathode for Li-S battery

    2015-05-01

    Full Text Available Lithium-sulfur (Li-S battery is a promising energy storage system due to its high energy density, cost effectiveness and environmental friendliness of sulfur. However, there are still a number of technical challenges, such as low Coulombic efficiency and poor long-term cycle life, impeding the commercialization of Li-S battery. The electrochemical performance of Li-S battery is closely related with the interfacial reactions occurring between hosting substrate and active sulfur species which are poorly conducting at fully oxidized and reduced states. Here, we correlate the relationship between the performance and interfacial reactions in the Li-S battery system, using a hollow carbon nanosphere (HCNS with highly graphitic character as hosting substrate for sulfur. With an appropriate amount of sulfur loading, HCNS/S composite exhibits excellent electrochemical performance because of the fast interfacial reactions between HCNS and the polysulfides. However, further increase of sulfur loading leads to increased formation of highly resistive insoluble reaction products (Li2S2/Li2S which limits the reversibility of the interfacial reactions and results in poor electrochemical performances. These findings demonstrate the importance of the interfacial reaction reversibility in the whole electrode system on achieving high capacity and long cycle life of sulfur cathode for Li-S batteries.

    Biomass-derived porous carbon has been considered as a promising sulfur host material for lithium-sulfur batteries because of its high conductive nature and large porosity. The present study explored biomass-derived porous carbon as polysulfide reservoir to modify the surface of glass fiber (GF) separator. Two different carbons were prepared from Oak Tree fruit shells by carbonization with and without KOH activation. The KOH activated porous carbon (AC) provides a much higher surface area (796 m2 g-1) than pyrolized carbon (PC) (334 m2 g-1). The R factor value, calculated from the X-ray diffraction pattern, revealed that the activated porous carbon contains more single-layer sheets with a lower degree of graphitization. Raman spectra also confirmed the presence of sp3-hybridized carbon in the activated carbon structure. The COH functional group was identified through X-ray photoelectron spectroscopy for the polysulfide capture. Simple and straightforward coating of biomass-derived porous carbon onto the GF separator led to an improved electrochemical performance in Li-S cells. The Li-S cell assembled with porous carbon modified GF separator (ACGF) demonstrated an initial capacity of 1324 mAh g-1 at 0.2 C, which was 875 mAh g-1 for uncoated GF separator (calculated based on the 2nd cycle). Charge transfer resistance (Rct) values further confirmed the high ionic conductivity nature of porous carbon modified separators. Overall, the biomass-derived activated porous carbon can be considered as a promising alternative material for the polysulfide inhibition in Li-S batteries. Copyright © 2017 Elsevier Inc.

    The mechanism of the sulfur cathode in Li-S batteries has been proposed. It was revealed by the real-time quantitative determination of polysulfide species and elemental sulfur by means of high-performance liquid chromatography in the course of the discharge and recharge of a Li-S battery. A three-step reduction mechanism including two chemical equilibrium reactions was proposed for the sulfur cathode discharge. The typical two-plateau discharge curve for the sulfur cathode can be explained. A two-step oxidation mechanism for Li2S and Li2S2 with a single chemical equilibrium among soluble polysulfide ions was proposed. The chemical equilibrium among S52-, S62-, S72-, and S82- throughout the entire oxidation process resulted for a single flat recharge curve in Li-S batteries.

    Mutations in the LIS1 gene result in isolated lissencephaly or subcortical band heterotopia. We report a 5-year-old male who presented with seizures and global developmental delay. Magnetic resonance imaging (MRI) demonstrated posteriorly predominant pachygyria and subcortical band heterotopia. His mother had a history of epilepsy, with onset in her teenage years. Her MRI revealed no abnormalities. Sequence analysis of the LIS1 gene identified a novel p.H389Y mutation in exon 11 (c.1165C>T). The child's mother was found to have the identical mutation as her son, with the signal intensity of the mutant allele being much lower than the normal allele, suggesting somatic mosaicism. This patient is one of only a few reported with a missense mutation in LIS1 associated with subcortical band heterotopia, and this is the first report of a mosaic individual having an affected child.

    Professional confidence is a concept that is frequently used and or implied in occupational therapy literature, but often without specifying its meaning. Rodgers's Model of Concept Analysis was used to analyse the term "professional confidence". Published research obtained from a federated search in four health sciences databases was used to inform the concept analysis. The definitions, attributes, antecedents, and consequences of professional confidence as evidenced in the literature are discussed. Surrogate terms and related concepts are identified, and a model case of the concept provided. Based on the analysis, professional confidence can be described as a dynamic, maturing personal belief held by a professional or student. This includes an understanding of and a belief in the role, scope of practice, and significance of the profession, and is based on their capacity to competently fulfil these expectations, fostered through a process of affirming experiences. Developing and fostering professional confidence should be nurtured and valued to the same extent as professional competence, as the former underpins the latter, and both are linked to professional identity.

    Classical lissencephaly, or isolated lissencephaly sequence (ILS), and subcortical band heterotopia (SBH) are neuronal migration disorders associated with severe mental retardation and epilepsy. Abnormalities of the LIS1 and DCX genes are implicated in the majority of patients with these disorders and account for approximately 75% of patients with ILS, whereas mutations of DCX account for 85% of patients with SBH. The molecular basis of disease in patients with ILS and SBH, in whom no abnormalities have been identified, has been questioned. We studied a series of 83 patients with ILS, SBH or pachygyria, in whom no abnormalities of the LIS1 or DCX genes had been identified, for intragenic deletions and duplications by multiplex ligation-dependent probe amplification (MLPA). In 52 patients with ILS, we identified 12 deletions and 6 duplications involving the LIS1 gene (35%), with the majority resulting in grade 3 lissencephaly. Three deletions of the DCX gene were identified in the group of nine female patients with SBH (out of 31 patients with DCX-suggestive brain anomalies), ie 33%. We estimate an overall mutation detection rate of approximately 85% by LIS1 and DCX sequencing and MLPA in ILS, and 90% by DCX sequencing and MLPA in SBH. Our results show that intragenic deletions and duplications of the LIS1 and DCX genes account for a significant number of patients with ILS and SBH, where no molecular defect had previously been identified. Incorporation of deletion/duplication analysis of the LIS1 and DCX genes will be important for the molecular diagnosis of patients with ILS and SBH.

    Li-S batteries are an emerging technology and the most promising successor of current lithium ion technology. While there is great perspective in terms of superior theoretical specific capacity and energy density great challenges have to be addressed. One major challenge, severely limiting cycle performance and capacity retention, is the shuttling of polysulphide species. In this contribution we show a reconfiguration of the usual Li-S cell. Instead of generating a carbon/sulphur composite by melt infiltration a highly porous, conductive nitrogen-rich carbon material (TNC) is coated onto a commercial polypropylene separator foil. The thin conductive coating of TNC on the separator enables the application of very simple sulphur/carbon black cathodes. Because the melt infiltration of sulphur in a porous host material becomes unnecessary the electrode processing is significantly simplified. The specific capacity and cycling stability of reconfigurated cells are both improved significantly compared to the performance of a standard cell setup using a pristine separator. At a constant charging rate of C/5 cells with modified separator showed 2.5 times higher residual capacity (1016 mAh g-1) than cells with pristine separator (405 mAh g-1).

    High-surface-area, nanostructured carbon is widely used for encapsulating sulfur and improving the cyclic stability of Li-S batteries, but the high carbon content and low packing density limit the specific energy that can be achieved. Here we report an approach that does not rely on sulfur encapsulation. We used a low-surface-area, open carbon fibre architecture to control the nucleation and growth of the sulfur species by manipulating the carbon surface chemistry and the solvent properties, such as donor number and Li+ diffusivity. Our approach facilitates the formation of large open spheres and prevents the production of an undesired insulating sulfur-containing film on the carbon surface. This mechanism leads to 100% sulfur utilization, almost no capacity fading, over 99% coulombic efficiency and high energy density (1,835 Wh kg-1 and 2,317 Wh l-1). This finding offers an alternative approach for designing high-energy and low-cost Li-S batteries through controlling sulfur reaction on low-surface-area carbon.

    The bispectral (BIS) monitor uses brain electroencephalographic data to measure the depth of sedation and pharmacological response during anaesthetic procedures. In this case, the BIS monitor was used for another purpose, to demonstrate postoperatively to the nursing staff that a patient with history of locked-in syndrome (LIS), who underwent pressure ulcer debridement, had periods of wakefulness and apparent sensation, even with his eyes closed. Furthermore, as patients with LIS can feel pain, despite being unable to move, local block or general anaesthesia should be provided for sharp surgical debridement and other painful procedures. This use of the BIS has shown that as a general rule, the staff should treat the patient as though he might be awake and sensate even if he does not open his eyes or move his limbs. The goal of this study was to continuously monitor pain level and communicate these findings to the entire wound team, i.e. anaesthesiologists, surgeons and nurses. © 2012 The Authors.

  5. One-Pot Synthesis of Graphene-Sulfur Composites for Li-S Batteries: Influence of Sulfur Precursors

    Directory of Open Access Journals (Sweden)

    James Guo Sheng Moo

    2017-12-01

    Full Text Available Lithium-sulfur (Li-S batteries are postulated as next-generation electrochemical energy storage devices due to their increased storage capabilities. However, challenges persist from the polysulfide-shuttle effect at the cathode. Soluble sulfur-based species in the cathode cross over to the lithium anode through the separator leading to fading capacity with cycling. This has spurred continuous effort by the scientific community to develop novel cathodes where sulfur species can affix better. A conductive nanostructured graphene network is a suitable candidate that can serve as a scaffold for holding sulfur nanoparticles. Here, a one-pot synthesis of chemically reduced graphene oxide networks prepared from easily accessible graphene oxide is demonstrated. The solution-based method simply allows for impregnation of the graphene oxide network with sulfur nanoparticles through a careful manipulation of pH of the chemical environment. Two routes were chosen for the precipitation of such sulfur nanoparticles: firstly, the dissolution of sulfur in sodium hydroxide into polysulfides followed by acidification and secondly, the acidification of sodium thiosulfate from alkaline media into sulfur nanoparticles. Both graphene oxide materials from the two routes were treated with sodium borohydride to achieve conductive graphene. The second route, with the sulfur nanoparticles derived from the acidification of sodium thiosulfate with chemically reduced graphene oxide, demonstrated favorable electrochemical behavior, showing promise as electrode material for Li-S batteries.

    Carbon hosts have been utilized to obtain composite cathodes with high sulfur loadings for Li-S batteries. However, the complicated synthesis process may hinder their practical applications. Their mechanical and electrochemical properties shall be further improved. Herein, a facile scalable dip-coating process is developed to synthesize a flexible composite cathode with a high sulfur loading. Via the process, a hybrid composed of carbon nanotubes, carbon black, sulfur, and titania nanoparticles is successfully conformally coated on the carbonized textile (c-textile). The formed flexible c-textile@S/TiO 2 cathodes with sulfur loadings of 1.5 and 3.0 mg cm -2 can deliver reversible discharge capacities of 860 and 659 mA h g -1 at 2 C, respectively. For the latter one, it can retain 94% of the initial capacity after 400 cycles with a high Coulombic efficiency (∼96%). When its sulfur loading is further increased to 7.0 mg cm -2 , its areal capacity reaches 5.2 mA h cm -2 . Such excellent performance is ascribed to the synergy effect of the three-dimension conductive hierarchical pore structure and TiO 2 additive. They can physically and chemically entrap the soluble polysulfides in the composite cathode. The as-synthesized free-standing composite electrode is of low cost and a high areal capacity, making it suitable for flexible energy storage applications based on Li-S batteries.

    Highlights: • CMT was synthesized by carbonizing poplar catkins and used in Li/S battery. • CMT with mesoporous surface is beneficial to trapping soluble polysulfides. • The S/CMT composite exhibited good cycling and rate capability. - Abstract: A carbon microtube (CMT) was synthesized by carbonizing the poplar catkin and composited with sulfur, serving as a cathode for lithium/sulfur batteries. Scanning electron microscopy and energy dispersive spectroscopy mapping showed the formation of a tubular structure with uniform sulfur coating on the surface of CMTs. The CMT with a mesoporous surface is beneficial to both trapping soluble polysulfide intermediates and rendering the electrical conductivity of the prepared electrode. The resulting S/CMT composite cathode can deliver an 810 mAh g{sup −1} reversible specific discharge capacity after 100 cycles at 0.1 C, and 585 mAh g{sup −1} at 1 C.

    Cecil, Daniel J.; Buechler, Dennis E.; Blakeslee, Richard J.

    2015-01-01

    The Tropical Rainfall Measuring Mission (TRMM) Lightning Imaging Sensor (LIS) has been collecting observations of total lightning in the global tropics and subtropics (roughly 38 deg S - 38 deg N) since December 1997. A similar instrument, the Optical Transient Detector, operated from 1995-2000 on another low earth orbit satellite that also saw high latitudes. Lightning data from these instruments have been used to create gridded climatologies and time series of lightning flash rate. These include a 0.5 deg resolution global annual climatology, and lower resolution products describing the annual cycle and the diurnal cycle. These products are updated annually. Results from the update through 2013 will be shown at the conference. The gridded products are publicly available for download. Descriptions of how each product can be used will be discussed, including strengths, weaknesses, and caveats about the smoothing and sampling used in various products.

  1. Attainable gravimetric and volumetric energy density of Li-S and li ion battery cells with solid separator-protected Li metal anodes.

    Science.gov (United States)

    McCloskey, Bryan D

    2015-11-19

    As a result of sulfur's high electrochemical capacity (1675 mA h/gs), lithium-sulfur batteries have received significant attention as a potential high-specific-energy alternative to current state-of-the-art rechargeable Li ion batteries. For Li-S batteries to compete with commercially available Li ion batteries, high-capacity anodes, such as those that use Li metal, will need to be enabled to fully exploit sulfur's high capacity. The development of Li metal anodes has focused on eliminating Coulombically inefficient and dendritic Li cycling, and to this end, an interesting direction of research is to protect Li metal by employing mechanically stiff solid-state Li(+) conductors, such as garnet phase Li7La3Zr2O12 (LLZO), NASICON-type Li1+xAlxTi2-x(PO4)3 (LATP), and Li2S-P2S5 glasses (LPS), as electrode separators. Basic calculations are used to quantify useful targets for solid Li metal protective separator thickness and cost to enable Li metal batteries in general and Li-S batteries specifically. Furthermore, maximum electrolyte-to-sulfur ratios that allow Li-S batteries to compete with Li ion batteries are calculated. The results presented here suggest that controlling the complex polysulfide speciation chemistry in Li-S cells with realistic, minimal electrolyte loading presents a meaningful opportunity to develop Li-S batteries that are competitive on a specific energy basis with current state-of-the-art Li ion batteries.

  2. Response of Global Lightning Activity Observed by the TRMM/LIS During Warm and Cold ENSO Phases

    Science.gov (United States)

    2007-01-01

    This paper investigates the response of global lightning activity to the transition from the warm (January February March-JFM 1998) to the cold (JFM 1999) ENSO phase. The nine-year global lightning climatology for these months from the Tropical Rainfall Measuring Mission (TRMM) Lightning Imaging Sensor (LIS) provides the observational baseline. Flash rate density is computed on a 5.0x5.0 degree lat/lon grid within the LIS coverage area (between approx.37.5 N and S) for each three month period. The flash rate density anomalies from this climatology are examined for these months in 1998 and 1999. The observed lightning anomalies spatially match the documented general circulation features that accompany the warm and cold ENSO events. During the warm ENSO phase the dominant positive lightning anomalies are located mostly over the Western Hemisphere and more specifically over Gulf of Mexico, Caribbean and Northern Mid-Atlantic. We further investigate specifically the Northern Mid-Atlantic related anomaly features since these show strong relation to the North Atlantic Oscillation (NAO). Furthermore these observed anomaly patterns show strong spatial agreement with anomalous upper level (200 mb) cold core cyclonic circulations. Positive sea surface temperature anomalies during the warm ENSO phase also affect the lightning activity, but this is mostly observed near coastal environments. Over the open tropical oceans, there is climatologically less lightning and the anomalies are less pronounced. Warm ENSO related anomalies over the Eastern Hemisphere are most prominent over the South China coast. The transition to the cold ENSO phase illustrates the detected lightning anomalies to be more pronounced over East and West Pacific. A comparison of total global lightning between warm and cold ENSO phase reveals no significant difference, although prominent regional anomalies are located over mostly oceanic environments. All three tropical "chimneys" (Maritime Continent, Central

  3. Atomic Sulfur Anchored on Silicene, Phosphorene, and Borophene for Excellent Cycle Performance of Li-S Batteries.

    Li, Fen; Zhao, Jijun

    2017-12-13

    Dissolution of intermediate lithium polysulfides (LiPS) is an inevitable obstacle for the solid sulfur-based cathode in Li-S batteries. For the first time, herein, atomic sulfur is incorporated into silicene, phosphorene, and borophene to intrinsically eliminate the dissolution of LiPS. The small molecular sulfur species are anchored on the silicene surface with stronger Si-S interaction than the P-S and B-S ones. Meanwhile, a high atomic sulfur coverage (63.1 wt %) is achieved in silicene and concomitantly stabilizes the silicene layer. For the S3-covered silicene, a high theoretical capacity of 857 mA h g-1 is achieved with slight dissolution of LiPS originated from the loss of interior S atoms that are not directly bound with silicene surface. By realizing the elemental S2 coverage on silicene with large surface area, the Li+ ions can react fast with the S2 species, leading to a high theoretical capacity of 891 mA h g-1 without dissolution and migration of the intermediate LiPS. Most interestingly, the discharge products of atomic layer of lithium sulfides on silicene surface exhibit completely different behaviors from the traditional discharge products of solid Li2S, which can function as effective adsorption and activation sites for the conversion of LiPS from long chain to short chain by accelerated redox reaction. The present study gains some key insights into how the atomic sulfur contributes to the intrinsic shuttle inhibition and offers a feasible way to design the atomic sulfur-based cathode materials of Li-S batteries with better electrochemical performance.

  4. Longitudinal Trends in Internationalisation, Collaboration Types, and Citation Impact: A Bibliometric Analysis of Seven LIS Journals (1980-2008

    Sei-Ching Joanna Sin

    2011-06-01

    Full Text Available Journal publication is a core avenue for sharing research in the LIS field. Effective scholarly communication is beneficial to the growth of a discipline. Bibliometrics research shows that articles in prestigious international journals are predominantly those of authors based in a few nations, however. Papers from authors outside the established nations are likely to be cited less often. This study analysed the longitudinal changes in geographical patterns of authorship, collaboration types, and factors affecting the citation impact of seven top LIS journals over a period of 29 years. In addition to data from all nations, this paper includes specific findings relating to Asian countries. Analysis of 8,140 papers shows that the internationalisation level in the sample set has increased in terms of number of nations represented and in a decreasing Gini coefficient. The presence of Asian nations such as Taiwan and Singapore as top contributing countries is particularly notable in the past 10 years. Domestic collaboration is found to be the dominant type of authorship pattern. In terms of citation impact as measured by citation counts, logistic regression was used to test the effects of author continent, country income level, collaboration type, publication year, and number of authors. Papers from lower-income countries or from Asian or European authors are found less likely to be ‘more cited.’ International and domestic collaboration had a positive relation with citation counts. A practical implication is that authors may consider international collaboration as a way to increase the visibility and impact of their research. Nevertheless, the reasons behind such differential citation impact require more exploration. Invisible colleges, the strengths of weak ties, and the geographic scope of a paper are some factors to be further examined. It is hoped that more research can help identify and overcome barriers in scholarly communication so as to

    A Morel-Lavallée lesion is a post-traumatic closed degloving injury of soft tissue. The lesion is due to a shearing trauma with separation of subcutaneous tissue from underlying fascia. When conservative treatment fails, surgical treatment is imperative. Commonly, open drainage and debridement is performed. This case report describes a Morel-Lavallée lesion of the knee in a professional soccer player who was successfully treated with endoscopic debridement and fibrin glue injection after failure of conservative management. This method achieves the goal of an open surgical debridement without exposing patients to an increased morbidity. Copyright © 2016. Published by Elsevier B.V.

    2017-04-01

    Drought and water scarcity are among the important issues facing several regions within Africa and the Middle East. A seamless and effective monitoring and early warning system is needed by regional/national stakeholders. Such system should support a proactive drought management approach and mitigate the socio-economic losses up to the extent possible. In this presentation, we report on the ongoing development and validation of a seasonal scale water deficit forecasting system based on NASA's Land Information System (LIS) and seasonal climate forecasts. First, our presentation will focus on the implementation and validation of the LIS models used for drought and water availability monitoring in the region. The second part will focus on evaluating drought and water availability forecasts. Finally, details will be provided of our ongoing collaboration with end-user partners in the region (e.g., USAID's Famine Early Warning Systems Network, FEWS NET), on formulating meaningful early warning indicators, effective communication and seamless dissemination of the monitoring and forecasting products through NASA's web-services. The water deficit forecasting system thus far incorporates NOAA's Noah land surface model (LSM), version 3.3, the Variable Infiltration Capacity (VIC) model, version 4.12, NASA GMAO's Catchment LSM, and the Noah Multi-Physics (MP) LSM (the latter two incorporate prognostic water table schemes). In addition, the LSMs' surface and subsurface runoff are routed through the Hydrological Modeling and Analysis Platform (HyMAP) to simulate surface water dynamics. The LSMs are driven by NASA/GMAO's Modern-Era Retrospective analysis for Research and Applications, Version 2 (MERRA-2), and the USGS and UCSB Climate Hazards Group InfraRed Precipitation with Station (CHIRPS) daily rainfall dataset. The LIS software framework integrates these forcing datasets and drives the four LSMs and HyMAP. The Land Verification Toolkit (LVT) is used for the evaluation of the

    Full Text Available With a large output of medical literature coming out every year, it is impossible for readers to read every article. Critical appraisal of scientific literature is an important skill to be mastered not only by academic medical professionals but also by those involved in clinical practice. Before incorporating changes into the management of their patients, a thorough evaluation of the current or published literature is an important step in clinical practice. It is necessary for assessing the published literature for its scientific validity and generalizability to the specific patient community and reader′s work environment. Simple steps have been provided by Consolidated Standard for Reporting Trial statements, Scottish Intercollegiate Guidelines Network and several other resources which if implemented may help the reader to avoid reading flawed literature and prevent the incorporation of biased or untrustworthy information into our practice.

  3. Literature promotion in Public Libraries

    This article discusses a model that can be used in order to analyse notions on literature promotion in public libraries. The model integrates different issues which interact with how literature promotion is understood and thought of in public libraries. Besides cultural policy we regard the logics...... of new public management (NPM) and professional logics in the field of public libraries. Cultural policy along with the identification of underlying logics present among politicians, government officials, managers and librarians/promoters of literature, play an important part in creating an understanding...... of literature promotion in Danish libraries. Thus the basic premise for the development of the model is that cultural policy (Policy) has an important influence on notions on literature promotion and other activities in public libraries, but that cultural policy must be seen in some kind of interaction...

  4. A condição feminina em Lisístrata e em A Fonte das Mulheres

    Full Text Available O presente trabalho dá enfoque à comédia grega Lisístrata (411 a.C, de Aristófanes, e a sua adaptação cinematográfica, o filme A Fonte das Mulheres (La Source des Femmes, 2011, coproduzido por França, Bélgica e Itália e dirigido pelo romeno Radu Mihaileanu. Ambas as obras trazem a questão da greve do sexo instaurada pelas mulheres, mas os motivos e os desdobramentos dessa greve são divergentes. Para desenvolvimento de nossa pesquisa, partimos da descrição de excertos da comédia e de cenas do filme, considerando as peculiaridades dos contextos de produção e recepção de cada uma delas, a fim de examinar as diferenças no que se refere ao tratamento dado às questões femininas nas obras citadas. Para fundamentar teoricamente o trabalho, recorremos a pesquisadores que se debruçaram sobre os estudos de tradução e adaptação, como Hermans (1992 e Lefevere (1992, e sobre o estudo da comédia grega, como Pompeu (1997 e Oliveira e Silva (1991. Uma vez que os contextos de produção e recepção das obras são distintos, as escolhas feitas durante a elaboração dessas narrativas também se diferenciam, o que aponta para um processo de reescritura do enredo. Os resultados demonstram que a obra cinematográfica, devido ao contexto no qual se insere, debate a condição feminina de modo diverso da comédia: enquanto a comédia aristofânica aborda a temática da mulher para discutir sobre a manutenção da pólis, o filme acolhe pontos de discussão importantes para o próprio movimento feminista e discute a opressão que o patriarcado impõe às mulheres

    Lithium-sulfur (Li-S) batteries are technologically significant for sulfur is cheap, and offers high gravimetric capacity and a large energy density. But achieving long term cyclability with moderate capacity loss, and scalability pose formidable challenges. A solution phase approach for the preparation of a composite of sulfur with hydroxyl groups functionalized multiwalled carbon nanotubes (MWCNTols) and coated with poly(3,4-ethylenedioxypyrrole) (PEDOP) is presented for the first time. Comparison of the Li-S performances at 0.1 C current-rate show that the S based cell with a S-loading of 80% retains a low capacity of 122 mAh gsulfur-1 after 100 cycles, whereas cells with S/MWCNTols and S/MWCNTols/PEDOP composites with sulfur loadings of 73 and 70% respectively, retain capacities of 384 and 624 mAh gsulfur-1 after 200 charge-discharge cycles, with Coulombic efficiencies of 96 and 98.7% respectively. This performance differential illustrates the role of PEDOP in inhibiting sulfur loss and in maximizing cell response. The polymer provides electrical interconnects between the insulating sulfur clusters and facilitates Li+ transfer at the interface. The ease of the synthesis, coupled with the remarkable cycling performance delivered by this composite at a high sulfur-loading, demonstrate the promise that this S/CNT/conducting polymer composite has for practical Li-S batteries.

    Conductive metal sulfides are promising multi-functional additives for future lithium-sulfur (Li-S) batteries. These can increase the sulfur cathode's electrical conductivity to improve the battery's power capability, as well as contribute to the overall cell-discharge capacity. This multi-functional electrode design showed initial promise; however, complicated interactions at the system level are accompanied by some detrimental side effects. The metal sulfide additives with a chemical conversion as the reaction mechanism, e.g., CuS and FeS2, can increase the theoretical capacity of the Li-S system. However, these additives may cause undesired parasitic reactions, such as the dissolution of the additive in the electrolyte. Studying such complex reactions presents a challenge because it requires experimental methods that can track the chemical and structural evolution of the system during an electrochemical process. To address the fundamental mechanisms in these systems, we employed an operando multimodal x-ray characterization approach to study the structural and chemical evolution of the metal sulfide-utilizing powder diffraction and fluorescence imaging to resolve the former and absorption spectroscopy the latter-during lithiation and de-lithiation of a Li-S battery with CuS as the multi-functional cathode additive. The resulting elucidation of the structural and chemical evolution of the system leads to a new description of the reaction mechanism.

    Many problems associated with Li-S and Na-S batteries essentially root in the generation of their soluble polysulfide intermediates. While conventional wisdom mainly focuses on trapping polysulfides at the cathode using various functional materials, few strategies are available at present to fully resolve or circumvent this long-standing issue. In this study, we propose the concept of sulfur-equivalent cathode materials, and demonstrate the great potential of amorphous MoS 3 as such a material for room-temperature Li-S and Na-S batteries. In Li-S batteries, MoS 3 exhibits sulfur-like behavior with large reversible specific capacity, excellent cycle life, and the possibility to achieve high areal capacity. Most remarkably, it is also fully cyclable in the carbonate electrolyte under a relatively high temperature of 55 °C. MoS 3 can also be used as the cathode material of even more challenging Na-S batteries to enable decent capacity and good cycle life. Operando X-ray absorption spectroscopy (XAS) experiments are carried out to track the structural evolution of MoS 3 It largely preserves its chain-like structure during repetitive battery cycling without generating any free polysulfide intermediates.

    2015-04-01

    The rise of social media has increased connectivity and blurred personal and professional boundaries, bringing new challenges for medical professionalism. Whether traditional professionalism principles apply to the online social media space remains unknown. The purpose of this synthetic literature review was to characterize the original peer-reviewed research studies published between 1 January 2000-1 November 2014 on online professionalism, to assess methodologies and approaches used, and to provide insights to guide future studies in this area. The investigators searched three databases and performed manual searches of bibliographies to identify the 32 studies included. Most studies originated in the USA. Cross-sectional surveys and analyses of publicly available online content were the most common methodologies employed. Studies covered the general areas of use and privacy, assessment of unprofessional online behaviours, consensus-gathering of what constitutes unprofessional or inappropriate online behaviours, and education and policies. Studies were of variable quality; only around half of survey studies had response rates of 50% or greater. Medical trainees were the most common population studied. Future directions for research include public perspectives of online professionalism, impact on patient trust, and how to use social media productively as medical professionals.

    We present results from the development towards the Time-of-Flight Laser Ion Source (ToF-LIS) aiming for the suppression of isobaric contaminants through fast beam gating. The capability to characterize high resistance ion sources has been successfully demonstrated. A ninefold selectivity gain has been achieved through suppression of surface ionized potassium, while maintaining >90% transmission for laser-ionized gallium using a thin wall graphite ionizer cavity combined with a fast beam gate. Initial results from the investigation of glassy carbon as a potential hot cavity ion source are presented. Power-cycle tests of a newly designed mount for fragile ion source cavities indicates its capability to survive the thermal stress expected during operation in an ISOLDE target unit. Finally, we introduce fast ion beam switching at a rate of 10 kHz using the ISOLDE ion beam switchyard as a new concept for ion beam distribution and conclude by highlighting the potential applications of this ion beam multiplexing te...

    In this paper we describe a modified (AEG/CH) coated separator for Li-S batteries in which the shuttling phenomenon of the lithium polysulfides is restrained through two types of interactions: activated expanded graphite (AEG) flakes interacted physically with the lithium polysulfides, while chitosan (CH), used to bind the AEG flakes on the separator, interacted chemically through its abundance of amino and hydroxyl functional groups. Moreover, the AEG flakes facilitated ionic and electronic transfer during the redox reaction. Live H-cell discharging experiments revealed that the modified separator was effective at curbing polysulfide shuttling; moreover, X-ray photoelectron spectroscopy analysis of the cycled separator confirmed the presence of lithium polysulfides in the AEG/CH matrix. Using this dual functional interaction approach, the lifetime of the pure sulfur-based cathode was extended to 3000 cycles at 1C-rate (1C = 1670 mA/g), decreasing the decay rate to 0.021% per cycle, a value that is among the best reported to date. A flexible battery based on this modified separator exhibited stable performance and could turn on multiple light-emitting diodes. Such modified membranes with good mechanical strength, high electronic conductivity, and anti-self-discharging shield appear to be a scalable solution for future high-energy battery systems.

    A novel spatial confinement strategy based on a carbon/TiO2 /carbon sandwich structure is proposed to synthesize TiC nanoparticles anchored on hollow carbon nanospheres (TiC@C) through a carbothermal reduction reaction. During the synthesis process, two carbon layers not only serve as reductant to convert TiO2 into TiC nanoparticles, but also create a spatial confinement to suppress the aggregation of TiO2 , resulting in the formation of well-dispersed TiC nanoparticles. This unique TiC@C structure shows an outstanding long-term cycling stability at high rates owing to the strong physical and chemical adsorption of lithium polysulfides (i.e., a high capacity of 732.6 mA h g-1 at 1600 mA g-1 ) and it retains a capacity of 443.2 mA h g-1 after 1000 cycles, corresponding to a decay rate of only 0.0395 % per cycle. Therefore, this unique TiC@C composite could be considered as an important candidate for the cathode material in Li-S batteries. © 2016 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.

    A linear algebraic solution is provided for the problem of retrieving the location and time of occurrence of lightning ground strikes from in Advanced Lightning Direction Finder (ALDF) network. The ALDF network measures field strength, magnetic bearing, and arrival time of lightning radio emissions and solutions for the plane (i.e.. no Earth curvature) are provided that implement all of these measurements. The accuracy of the retrieval method is tested using computer-simulated data sets and the relative influence of bearing and arrival time data on the outcome of the final solution is formally demonstrated. The algorithm is sufficiently accurate to validate NASA's Optical Transient Detector (OTD) and Lightning Imaging System (LIS). We also introduce a quadratic planar solution that is useful when only three arrival time measurements are available. The algebra of the quadratic root results are examined in detail to clarify what portions of the analysis region lead to fundamental ambiguities in source location. Complex root results are shown to be associated with the presence of measurement errors when the lightning source lies near an outer sensor baseline of the ALDF network. For arbitrary noncollinear network geometries and in the absence of measurement errors, it is shown that the two quadratic roots are equivalent (no source location ambiguity) on the outer sensor baselines. The accuracy of the quadratic planar method is tested with computer-generated data sets and the results are generally better than those obtained from the three station linear planar method when bearing errors are about 2 degrees.

    Sulfur is a promising cathode material with a high theoretical capacity of 1672 mAh g-1, however, the practical energy density of Li-S battery is far away from such promising due to its low active material utilization and low sulfur loading. Moreover, the challenges of the low electrical conductivity of sulfur and the high solubility of polysulfide intermediates still hinder its practical application. Here, we report a kind of free-standing and foldable cathodes consisting of 3D activated carbon fiber matrix and sulfur cathode. The 3D activated carbon fiber matrix (ACFC) has continuous conductive framework and sufficient internal space to provide a long-distance and continuous high-speed electron pathway. It also gives a very larger internal space and tortuous cathode region to ACFC accommodate a highly sulfur loading and keeps polysulfide within the cathode. The unique structured 3D foldable sulfur cathode using a foldable ACFC as matrix delivers a reversible capacity of about 979 mAh g-1 at 0.2C, a capacity retention of 98% after 100 cycles, and 0.02% capacity attenuation per cycle. Even at an areal capacity of 6 mAh cm-2, which is 2 times higher than the values of Li-ion battery, it still maintains an excellent rate capability and cycling performance.

    2017-11-01

    Lithium-sulfur (Li-S) batteries are regarded as a potential next-generation energy storage system but they are hampered by low active-material utilization, polysulfide shuttling, and rapid capacity fade. We present here the use of lightweight boron- and nitrogen-doped reduced graphene oxide (B-rGO, N-rGO) coated separators to suppress polysulfide diffusion and enhance active material utilization at high sulfur contents. B-rGO and N-rGO are synthesized through a facile modified Hummer's method involving the exfoliation of graphite sheets. Upon reduction, the carbon forms valuable interlayers with dynamic spacings for polysulfide trapping. Freeze-drying is utilized to preserve the structure of the pillow-like carbon, which is then slurry-coated onto a separator and placed against a sulfur cathode. The advantages of boron and nitrogen and their affinity towards polysulfides is compared while noting the lighter carbon coatings with good electrochemical stability. The cells attain a loading of 4.0 mg cm-2 with a high sulfur content of 66.5 ± 0.5 wt % on including the weight of the coatings. After a long cycle life of 400 cycles, N-rGO and B-rGO are still able to maintain a specific capacity of, respectively, 430 mA h g-1 and 367 mA h g-1.

    High-capacity electrochemical active material-based electrodes for lithium ion batteries (LIBs), such as sulfur (S), always face the collapse of the electrode due to the big volume change during insertion of the lithium (Li) ion and therefore shorten the cycle life of the cells. Herein, a series of design from the viewpoint of both individual components and the entire cathode in lithium-sulfur (Li-S) cell was introduced aiming at addressing the issues of poor conductivity, leakage of intermediate polysulphides, and large volumetric expansion upon insertion of the Li ion. In the designed electrode, polydopamine (PD)-coated S nanosheets (NSs) were used as active materials, carboxylic acid functionalized multiwall carbon nanotube (MWCNT-COOH) as conductive additives, and poly(acrylic acid) (PAA) as binders. Far different from the traditional hydrogen bond and/or van der Waals force linked electrodes, stronger covalent bonds formed by cross-linking of PD/MWCNT-COOH and PD/PAA into amide bonds, respectively, were built throughout the whole electrode to firmly integrate all of the individual components in the electrode together. As a result, the cathode demonstrated excellent cyclic performance with a charge capacity of 640 mAh/g after 500 cycles at a current density of 1 A/g. Besides, the charge capacity decay after 500 cycles is as small as 0.021% per cycle, which represents the best capacity retention so far.

    Investigations of the Ag (I)-substituted Keggin K3[H3AgIPW11O39] as a bi-functional Lewis acid and basic catalyst are reported that explore the stabilization of Li2Sn moieties so that reversible redox reactions in S-based elec-trodes would be possible. Spectroscopic investigations showed that the Li2Sn-moieties can be strongly adsorbed on the {AgIPW11O39} cluster, where the Ag(I) ion can act as Lew-is acid site to further enhance the adsorption of the S-moieties, and these interactions were investigated and ra-tionalized using DFT. These results were used to construct an electrode for use in a Li-S battery with a very high S utili-zation of 94%, and a coulometric capacity of 1580 mAh g-1. This means, as a result of using the AgPOM, both a high active S content, as well as a high areal S mass loading, is achieved in the composite electrode giving a highly stable battery with cycling performance at high rates (1050 and 810 mAh g-1 at 1C and 2C over 100 to 300 cycles respectively).

    Typical engineering methods utilized to calculate stresses on a roof structure involve simplifying assumptions that render a complex non-linear structure a simple and basic determinate beam. That is, instead of considering the composite action of the entire roof structure, the engineer evaluates only a single beam that is deemed conservatively to represent an affected rafter or top chord of a truss. This simplification based on assumptions of a complex problem is where significant conservatism can be introduced. Empirical data will be developed to evaluate this issue. Simple wood beams will be tested to failure. More complex and complete sections of roof structures that include composite action will also be tested to failure. The results can then be compared. An initial step in this process involves a literature review of any work that has been performed on roof structure composite action. The following section summarizes the literature review that was completed.

    To conduct an integrative review and synthesize current primary studies of professional ethics in nursing. Professional ethics is a familiar concept in nursing and provides an ethical code for nursing practice. However, little is known about how professional ethics has been defined and studied in nursing science. Systematic literature searches from 1948-February 2013, using the CINAHL, PubMed and Scopus electronic databases to look at previously published peer-reviewed studies. A modified version of Cooper's five-stage integrative review was used to review and synthesize current knowledge. Fourteen papers were included in this research. According to our synthesis, professional ethics is described as an intra-professional approach to care ethics and professionals commit to it voluntarily. Professional ethics consist of values, duties, rights and responsibilities, regulated by national legislation and international agreements and detailed in professional codes. Professional ethics is well established in nursing, but is constantly changing due to internal and external factors affecting the profession. Despite the obvious importance of professional ethics, it has not been studied much in nursing science. Greater knowledge of professional ethics is needed to understand and support nurses' moral decision-making and to respond to the challenges of current changes in health care and society. © 2015 John Wiley & Sons Ltd.

    Full Text Available Job stress is a line, for the person at work hired adverse physiological, psychological and behavioral reactions to situations in which job requirements are not in accordance with its capabilities, abilities and needs. Sources of stress at work are numerous. Personal factors: personality types have been most studied so far, environmental changes and demographic characteristics as well. Interpersonal stress inducing factors act and influence to the occurrence of many psychosomatic diseases. Psychosocial climate and relationships which are prevented or encouraged such as: cooperation and competition, trust and suspicion certainly affect to the appearance of professional stress. The way of leadership is very important. Organizational factors are the type of work, work time, noncompliance of the job, the introduction of new ethnologies, the conflict of personal roles, fear of job loss, bad physical conditions of working environment. The consequences of stress at work are numerous: at the cognitive level, the emotional level, the production plan, the health, plan reduces the immune system that cause a variety of psychosomatic illnesses and accidents at work.

    Rehabilitation nursing is practiced in various settings along the healthcare continuum. No framework is noted in the literature that defines the necessary competencies of the rehabilitation nurse. To develop a Competency Model for Professional Rehabilitation Nursing and its application to clinical and educational practice. A seven-member Association of Rehabilitation Nurses (ARN) task force was convened; conducted a literature review, reviewed current and historical ARN documents, including the Strategic Plan, and developed a Competency Model for Professional Rehabilitation Nursing practice. The Competency Model for Professional Rehabilitation Nursing delineates four domains of rehabilitation nursing practice and essential role competencies. The Competency Model for Professional Rehabilitation Nursing addresses this diverse specialty practice in the current healthcare arena. This framework can be used to guide nurses practicing at different levels of proficiency in various settings. The Competency Model can be used as a structure for staff orientation, evaluation tools, clinical ladder components, role descriptions and rehabilitation nursing courses. © 2015 Association of Rehabilitation Nurses.

    In this study, professional impact is defined as the academic literature that is cited in the literature that is used by professions in order to pursue skilled activities that are specific to their expertise. Specifically, we are focusing on the clinical guidelines that are used in the many health and medical professions that are issued by government bodies at national and international levels to ensure a certain quality level and to make results comparable at the national level. To date, more than 50.000 references have been identified in about 500 Swedish clinical guidelines issued by the above mentioned governmental bodies in Sweden. Of these, 73 % of the references have been matched to a PubMed id. The goal of this project is to develop a conceptual and theoretical contribution to the development of indicators for measuring the impact of research outside of the specifically academic literature.

    accidents and mental disorders will be the main health problems in the first third of the XXI Century. The Spanish Law for drivers (RD 818/2009 Reglamento General de Conductores mentions the necessity of meeting certain psychophysical requirements to obtain a driving license. Psychological tests approved in Spain are: ASDE Driver Test N-845, 100 and Coordinator LNDETER 2000. Objectives: Investigate the driving ability of people with mental disorders and know the legal aspects of professional drivers' fitness assessment. Methods: We conducted a research in different databases, libraries and out of a collection of 909 articles, 17 of them were selected for full revision. Mental disorders were classified according to Spanish regulation for drivers into 11 groups. We selected 8, because we considered them to be the most relevant. Results: RD 818/2009 strictly regulates the fitness for work of patients with mental disorders. Around 80% of patients with mental disorders do not pass the fitness tests, unless they have few symptoms, or those patients who have a favourable psychiatrist or psychologist report. Conclusions: The Spanish Law for drivers mentions that driving limitations must be accredited by a specialized physician. There is not enough evidence of the sensitivity and specificity of psycho-technical tests used in detecting mental disorders. The patient has a moral duty to inform his doctor about his pathology if it implies danger for others, but there is not a legal obligation.

  2. Directly Formed Alucone on Lithium Metal for High Performance Li Batteries and Li-S Batteries with High Sulfur Mass-loading.

    Lithium metal is considered the "holy grail" of next-generation battery anodes. However, severe parasitic reactions at the lithium-electrolyte interface deplete the liquid electrolyte, and the uncontrolled formation of high surface area and dendritic lithium during cycling cause rapid capacity fading and battery failure. Engineering a dendrite-free lithium metal anode is therefore critical for the development of long-life batteries using lithium anodes. In this study, we deposit a conformal, organic/inorganic hybrid coating, for the first time, directly on lithium metal using molecular layer deposition (MLD) to alleviate these problems. This hybrid organic/inorganic film with high cross-linking structure can stabilize lithium against dendrite growth, and minimize side reactions, as indicated by scanning electron microscope. We discovered that the alucone coating yielded several times longer cycle life at high current rates compared to the uncoated lithium, and achieved a steady Coulombic efficiency of 99.5%, demonstrating that the highly cross-linking structured material with great mechanical properties and good flexibility can effectively suppress dendrites formations. The protected Li was further evaluated in lithium-sulfur (Li-S) batteries with high sulfur mass loading of ~5 mg/cm2. After 140 cycles at a high current rate of ~1 mA/cm2, the alucone-coated Li-S batteries delivered the capacity of 657.7 mAh/g, 39.5% better than the bare lithium-sulfur battery. The report originally suggests that the flexible coating with high cross-linking structure by MLD is effective to enable lithium protection and offers a very promising avenue for improved performance in the real applications of Li-S batteries.

  3. Effect of Hydrofluoroether Cosolvent Addition on Li Solvation in Acetonitrile-Based Solvate Electrolytes and Its Influence on S Reduction in a Li-S Battery.

    Li-S batteries are a promising next-generation battery technology. Due to the formation of soluble polysulfides during cell operation, the electrolyte composition of the cell plays an active role in directing the formation and speciation of the soluble lithium polysulfides. Recently, new classes of electrolytes termed "solvates" that contain stoichiometric quantities of salt and solvent and form a liquid at room temperature have been explored due to their sparingly solvating properties with respect to polysulfides. The viscosity of the solvate electrolytes is understandably high limiting their viability; however, hydrofluoroether cosolvents, thought to be inert to the solvate structure itself, can be introduced to reduce viscosity and enhance diffusion. Nazar and co-workers previously reported that addition of 1,1,2,2-tetrafluoroethyl 2,2,3,3-tetrafluoropropyl ether (TTE) to the LiTFSI in acetonitrile solvate, (MeCN)2-LiTFSI, results in enhanced capacity retention compared to the neat solvate. Here, we evaluate the effect of TTE addition on both the electrochemical behavior of the Li-S cell and the solvation structure of the (MeCN)2-LiTFSI electrolyte. Contrary to previous suggestions, Raman and NMR spectroscopy coupled with ab initio molecular dynamics simulations show that TTE coordinates to Li(+) at the expense of MeCN coordination, thereby producing a higher content of free MeCN, a good polysulfide solvent, in the electrolyte. The electrolytes containing a higher free MeCN content facilitate faster polysulfide formation kinetics during the electrochemical reduction of S in a Li-S cell likely as a result of the solvation power of the free MeCN.

    The aim of this concept analysis is to clarify the meaning of professional nursing values. In a time of increasing ethical dilemmas, it is essential that nurses internalize professional values to develop and maintain a professional identity. However, nursing organizations and researchers provide different conceptions of professional nursing values, leading to a lack of clarity as to the meaning and attributes of this construct. Walker and Avant's (2011) method was used to guide an analysis of this concept. Resources published from 1973 to 2016 were identified via electronic databases and hand-searching of reference lists. A review of the literature was completed and the data were analyzed to identify uses of the concept; the defining attributes of the concept; borderline, related, contrary, and illegitimate examples; antecedents and consequences; and empirical referents. Professional nursing values were defined as important professional nursing principles of human dignity, integrity, altruism, and justice that serve as a framework for standards, professional practice, and evaluation. Further research is needed in the development and testing of professional nursing values theory, and the reassessment of values instruments. Core professional values that are articulated may help unify the profession and demonstrate the value of nursing to the public. © 2017 Wiley Periodicals, Inc.

    A surface coating that simultaneously suppressed Li dendrite growth and polysulfide shuttling on a lithium anode was successfully developed using a polymer blend composed of Nafion® and polyvinylidene difluoride (PVDF). This hierarchically nanostructured composite coating efficiently alleviated the swelling and dissolution problems of cation-selective Nafion® in the electrolyte and provided sufficient mechanical strength to accommodate large volumetric variations in the Li anode during charge-discharge cycles. The Nafion®/PVDF-coated Li anode exhibited substantially enhanced rate performance and cyclability as well as improved Coulombic efficiency for Li-S prototype batteries with a high-S-content cathode.

    High energy density and long-term stability of Li-S batteries are achieved by employing a 3D sponge-like carbon nanotube cathode and a liquid-type polysulfide catholyte. Carbon nanotubes not only provide excellent electron pathways and polysulfide reservoirs, but they can also be used as a standalone cathode without current collectors, which greatly alleviates problems arising from insulating sulfur and polysulfide shuttles as well as remarkably increasing the energy density. © 2014 WILEY-VCH Verlag GmbH & Co.

    2014-06-01

    Human health is dependent upon environmental sustainability. Many have argued that environmental sustainability advocacy and environmentally responsible healthcare practice are imperative healthcare actions. What are the key obstacles to healthcare professionals supporting environmental sustainability? How may these obstacles be overcome? Data-driven thematic qualitative analysis of semi-structured interviews identified common and pertinent themes, and differences between specific healthcare disciplines. A total of 64 healthcare professionals and academics from all states and territories of Australia, and multiple healthcare disciplines were recruited. Institutional ethics approval was obtained for data collection. Participants gave informed consent. All data were de-identified to protect participant anonymity. Qualitative analysis indicated that Australian healthcare professionals often take more action in their personal than professional lives to protect the environment, particularly those with strong professional identities. The healthcare sector's focus on economic rationalism was a substantial barrier to environmentally responsible behaviour. Professionals also feared conflict and professional ostracism, and often did not feel qualified to take action. This led to healthcare professionals making inconsistent moral judgements, and feeling silenced and powerless. Constraints on non-clinical employees within and beyond the sector exacerbated these difficulties. The findings are consistent with the literature reporting that organisational constraints, and strong social identification, can inhibit actions that align with personal values. This disparity can cause moral distress and residue, leading to feelings of powerlessness, resulting in less ethical behaviour. The data highlight a disparity between personal and professional actions to address environmental sustainability. Given the constraints Australian healthcare professionals encounter, they are unlikely to

    The term professionalism is embedded within curriculum and occupational therapy documents, yet, explicit discussion of the concept is lacking in the literature. This paper strives for a greater understanding of how professionalism is currently conceptualised within Western occupational therapy literature. A broad literature search was conducted and included international peer-reviewed and grey literature from Western cultures including Australia, Canada, New Zealand, the United Kingdom and the United States. To enrich understanding, some documents from medicine were also included. Professionalism is widely upheld as a core construct of occupational therapy. However, an evidence-based consensus of the specific elements of professionalism guiding occupational therapy practice is lacking. Currently, understanding of professionalism is largely based on multiple, isolated concepts presented in Western professional association documents. Acknowledging the multifaceted and multicultural nature of professionalism is essential to begin systematically delineating and conceptualising elements of professionalism specific to occupational therapy. This review has been conducted from a solely Western cultural lens. Additional work to highlight differences specific to international contexts, cultures, and societal influences is needed to enrich the understanding of professionalism in occupational therapy practice. © 2015 Occupational Therapy Australia.

    We evaluate hydrofluoroether (HFE) cosolvents with varying degrees of fluorination in the acetonitrile-based solvate electrolyte to determine the effect of the HFE structure on the electrochemical performance of the Li-S battery. Solvates or sparingly solvating electrolytes are an interesting electrolyte choice for the Li-S battery due to their low polysulfide solubility. The solvate electrolyte with a stoichiometric ratio of LiTFSI salt in acetonitrile, (MeCN)(2)-LiTFSI, exhibits limited polysulfide solubility due to the high concentration of LiTFSI. We demonstrate that the addition of highly fluorinated HFEs to the solvate yields better capacity retention compared to that of less fluorinated HFE cosolvents. Raman and NMR spectroscopy coupled with ab initio molecular dynamics simulations show that HFEs exhibiting a higher degree of fluorination coordinate to Li+ at the expense of MeCN coordination, resulting in higher free MeCN content in solution. However, the polysulfide solubility remains low, and no crossover of polysulfides from the S cathode to the Li anode is observed.

    2017-02-25

    Objectives. To describe the implementation of a high-stakes rubric to assess student professionalism in introductory and advanced pharmacy practice experiences (IPPEs and APPEs) to promote the professional socialization of students in the doctor of pharmacy (PharmD) program at Western New England University (WNE). Findings. A professionalism rubric was adapted from the literature to assess the professional behavior of students enrolled in experiential courses based on evaluation of the following criteria: appropriate communication skills with patients and providers, appearance and dress code, timeliness, and initiative. The rubric was implemented in the fall semester of 2013 as a high-stakes component of the assessment within all experiential courses. Students were required to meet expectations for each of the four criteria in order to pass the practice experience, independent of their performance in other course components. Students were assessed by their preceptors at the midpoint and end of each practice experience using the appropriate evaluation tool. Each of the IPPE and APPE evaluation tools included the professionalism rubric as a requirement for assessment. Use of the Professionalism Rubric as a high-stakes assessment tool highlighted professionalism as an important component of the program, making expectations explicit to students and providing leverage to preceptors for holding students accountable. Summary. The Office of Experiential Affairs at WNE has raised awareness of the importance of professionalism and promoted the professional socialization of PharmD students with the use of a high-stakes professionalism rubric.

    There has been substantial interest and emphasis on medical professionalism over the past twenty years. This speaks to the history of the medical profession, but increasingly to a broader understanding of the importance of socialisation and professional identity formation. A literature review was undertaken of professionalism and the role of professions and medical professional organisations. A key outcome has been the recognition that medical professionalism must be actively taught and assessed. Substantial effort is required to improve the educational environment, so that it nurtures the development of professionalism within the work-place. Although medical colleges have been prominent in identifying and progressing the recent developments within professionalism there is still much to be done to deliver fully on the societal contract between the public and the profession. There are key gaps to address, particularly with regards to self-regulation, civil behaviour and effective leadership and advocacy. Medical colleges need to take direct responsibility for the professionalism of their members. The expectations of the community are increasingly clear in this regard.

  4. Professionalism: a framework to guide medical education.

    Brody, Howard; Doukas, David

    2014-10-01

    Despite considerable advances in the incorporation of professionalism into the formal curriculum, medical students and residents are too often presented with a mechanical, unreflective version of the topic that fails to convey deeper ethical and humanistic aspirations. Some misunderstandings of professionalism are exacerbated by commonly used assessment tools that focus only on superficially observable behaviour and not on moral values and attitudes. Following a selective literature review, we engaged in philosophical ethical analysis to identify the key precepts associated with professionalism that could best guide the development of an appropriately reflective curriculum. The key precepts needed for a robust presentation of professionalism can be grouped under two headings: 'Professionalism as a trust-generating promise' (representing commitment to patients' interests, more than a mere business, a social contract, a public and collective promise, and hard work), and 'Professionalism as application of virtue to practice' (based on virtue, deeper attitudes rather than mere behaviour, and requiring of practical wisdom). These key precepts help students to avoid many common, unreflective misunderstandings of professionalism, and guide faculty staff and students jointly to address the deeper issues required for successful professional identity formation. © 2014 John Wiley & Sons Ltd.

    Burford, Bryan; Morrow, Gill; Rothwell, Charlotte; Carter, Madeline; Illing, Jan

    2014-04-01

    Despite a growing and influential literature, 'professionalism' remains conceptually unclear. A recent review identified three discourses of professionalism in the literature: the individual; the interpersonal, and the societal-institutional. Although all have credibility and empirical support, there are tensions among them. This paper considers how these discourses reflect the views of professionalism as they are expressed by students and educator-practitioners in three health care professions, and their implications for education. Twenty focus groups were carried out with 112 participants, comprising trainee and educator paramedics, occupational therapists and podiatrists. The focus group discussions addressed participants' definitions of professionalism, the sources of their perceptions, examples of professional and unprofessional behaviour, and the point at which participants felt one became 'a professional'. Analysis found views of professionalism were complex, and varied within and between the professional groups. Participants' descriptions of professionalism related to the three discourses. Individual references were to beliefs or fundamental values formed early in life, and to professional identity, with professionalism as an aspect of the self. Interpersonal references indicated the definition of 'professional' behaviour is dependent on contextual factors, with the meta-skill of selecting an appropriate approach being fundamental. Societal-institutional references related to societal expectations, to organisational cultures (including management support), and to local work-group norms. These different views overlapped and combined in different ways, creating a complex picture of professionalism as something highly individual, but constrained or enabled by context. Professionalism is grown, not made. The conceptual complexity identified in the findings suggests that the use of 'professionalism' as a descriptor, despite its vernacular accessibility, may be

    Yang, Homer

    2017-02-01

    Is professionalism in medicine just another bureaucratic imposition on our practice or a fundamental concept for physicians at all stages in their career? In this review, the historical perspectives of professionalism are explored as well as the what, why, and how questions concerning this topic. The key words "professionalism" and "anesthesia" were used to conduct a search of the PubMed database, the policies and publications of relevant Canadian and international physician regulatory bodies and organizations, historical documents, and other internet publications. Professionalism in anesthesia has a long history. While there are many definitions for professionalism, some very dated, all are based on virtues, behaviour, or professional identity. Professionalism plays a central role in the balance between physician autonomy and social contract, and it has a significant impact on patient safety and medicolegal litigation. Considerable evidence exists to suggest that professionalism must be treated seriously, particularly in these times of social accountability and budgetary pressures.

    2012-09-01

    Full Text Available Background The constantly growing publication rate of medical research articles puts increasing pressure on medical specialists who need to be aware of the recent developments in their field. The currently used literature retrieval systems allow researchers to find specific papers; however the search task is still repetitive and time-consuming. Aims In this paper we describe a system that retrieves medical publications by automatically generating queries based on data from an electronic patient record. This allows the doctor to focus on medical issues and provide an improved service to the patient, with higher confidence that it is underpinned by current research. Method Our research prototype automatically generates query terms based on the patient record and adds weight factors for each term. Currently the patient’s age is taken into account with a fuzzy logic derived weight, and terms describing blood-related anomalies are derived from recent blood test results. Conditionally selected homonyms are used for query expansion. The query retrieves matching records from a local index of PubMed publications and displays results in descending relevance for the given patient. Recent publications are clearly highlighted for instant recognition by the researcher. Results Nine medical specialists from the Royal Adelaide Hospital evaluated the system and submitted pre-trial and post-trial questionnaires. Throughout the study we received positive feedback as doctors felt the support provided by the prototype was useful, and which they would like to use in their daily routine. Conclusion By supporting the time-consuming task of query formulation and iterative modification as well as by presenting the search results in order of relevance for the specific patient, literature retrieval becomes part of the daily workflow of busy professionals.

  9. Supporting students in professional socialisation: Guidelines for professional nurses and educators

    Directory of Open Access Journals (Sweden)

    Hester Cathrina (Rina de Swardt

    2017-01-01

    Full Text Available Professional socialisation of nursing students involves learning skills, attitudes, behaviour and professional roles, largely in the clinical area. During clinical accompaniment and reflective discussions with a group of undergraduate Baccalaureate nursing students in South Africa, students reported negative professional socialisation experiences, primarily in the clinical area. Such experiences could influence the quality of patient care. The objective of this study was to develop and validate guidelines to support professional nurses and educators in the professional socialisation of student nurses. Evidence was generated from an exploration and description of the perceptions of professional nurses regarding their role in the professional socialisation of students, the perceptions of nurse educators regarding the teaching and facilitation of professional socialisation of students, and the socialisation experiences of students. Following a sequential mixed-methods design, qualitative data guided the collection of quantitative data. All data and literature directed the development of these guidelines, which experts reviewed and validated according to a set of criteria. These guidelines focus on the clinical, nursing educational institution environment and values and beliefs of the nursing profession. Facilitation of sound work ethics, professional behaviour, cultural and gender awareness, role modelling and the application of a range of teaching strategies is proposed.

    Full Text Available Professional performance in education is now calling the attention of researcher due to its role in the professionalizing process intended to increase international education standards. In this article the term professional performance is examined from the two socio-historic traditional roles involved in training the individuals as a bio-psychic and social entity: teachers and executive. By means of scientific methods, the author gives the theoretical grounds connecting professional performance, learning and individual capacity of using them in solving problem at his labor position. The professional performance is regarded as a human value that stimulates the activity. By predicting educational alternatives, the paper portraits a model of professional performance in education, referring the necessary actions needed for achieving the goals of education. Searching and discussing such alternatives leads to reinterpret professional problems and to find out ways of improving educational standards.

  16. Porous Carbon Mat as an Electrochemical Testing Platform for Investigating the Polysulfide Retention of Various Cathode Configurations in Li-S Cells.

    Chung, Sheng-Heng; Singhal, Richa; Kalra, Vibha; Manthiram, Arumugam

    2015-06-18

    Two optimized cathode configurations (a porous current collector and an interlayer) are utilized to determine the better architecture for improving the cycle stability and reversibility of lithium-sulfur (Li-S) cells. The electrochemical analysis on the upper-plateau discharge capacity (QH) and the lower-plateau discharge capacity (QL) is introduced for assessing, respectively, the polysulfide retention and the electrochemical reactivity of the cell. The analysis results in line with the expected materials chemistry principles suggest that the interlayer configuration offers stable cell performance for sulfur cathodes. The significance of the interlayer is to block the free migration of the dissolved polysulfides, which is a key factor for immobilizing and continuously utilizing the active material in sulfur cathodes. Accordingly, the carbon mat interlayers provide sulfur cathodes with a high discharge capacity of 864 mA h g(-1) at 1 C rate with a high capacity retention rate of 61% after 400 cycles.

  17. Acetylene Black/Sulfur Composites Synthesized by a Solution Evaporation Concentration Crystallization Method and Their Electrochemical Properties for Li/S Batteries

    Directory of Open Access Journals (Sweden)

    Zhigao Yang

    2013-07-01

    Full Text Available A novel technique to prepare carbon/sulfur composites as cathode materials for Li/S batteries is proposed, which we call the ‘solution evaporation concentration crystallization’ method. Three composites with different S loadings were prepared, subject to two different solvent evaporation rates from acetylene black (AB/sulfur in carbon disulfide solutions. X-ray diffraction, environmental scanning electron microscopy, transmission electron microscopy, and Brunauer-Emmett-Teller measurements all show that the porous AB structure is well-filled with S. Composites prepared at a lower solvent evaporation rate with 50 wt % S content, had good electrochemical properties, with 1609.67 mAh g−1 after 100 cycles. Composites with better dispersibility at a low solvent evaporation rate can effectively prevent polysulfide from dissolving in the electrolyte, and serve to stabilize the structure of the S cathode during the charge-discharge process.

  18. Determination of the Global-Average Charge Moment of a Lightning Flash Using Schumann Resonances and the LIS/OTD Lightning Data

    Science.gov (United States)

    Boldi, Robert; Williams, Earle; Guha, Anirban

    2018-01-01

    In this paper, we use (1) the 20 year record of Schumann resonance (SR) signals measured at West Greenwich Rhode Island, USA, (2) the 19 year Lightning Imaging Sensor (LIS)/Optical Transient Detector (OTD) lightning data, and (3) the normal mode equations for a uniform cavity model to quantify the relationship between the observed Schumann resonance modal intensity and the global-average vertical charge moment change M (C km) per lightning flash. This work, by integrating SR measurements with satellite-based optical measurements of global flash rate, accomplishes this quantification for the first time. To do this, we first fit the intensity spectra of the observed SR signals to an eight-mode, three parameter per mode, (symmetric) Lorentzian line shape model. Next, using the LIS/OTD lightning data and the normal mode equations for a uniform cavity model, we computed the expected climatological-daily-average intensity spectra. We then regressed the observed modal intensity values against the expected modal intensity values to find the best fit value of the global-average vertical charge moment change of a lightning flash (M) to be 41 C km per flash with a 99% confidence interval of ±3.9 C km per flash, independent of mode. Mode independence argues that the model adequately captured the modal intensity, the most important fit parameter herein considered. We also tested this relationship for the presence of residual modal intensity at zero lightning flashes per second and found no evidence that modal intensity is significantly different than zero at zero lightning flashes per second, setting an upper limit to the amount of nonlightning contributions to the observed modal intensity.

Median follow-up was 2.8 (2.1, 3.5 years. 31.5% of the patients died during this period. The main cause of death (36% was re-MI, and 22.4% of patients died from the heart failure. The relative risk (RR of death was significantly increased with the age of patients (RR=1.1. The probability of death increased in the presence of diabetes mellitus (RR=1.4, alcohol abuse (RR=2.3, any signs of consciousness disorders in the acute phase of MI (RR=1.6, heart failure (RR=1.6, atrial fibrillation (RR=1.4. Patients who were treated with calcium channel blockers before admission to the hospital, had a lower risk of death than those who did not receive these drugs (RR=0.4. Prescription of ACE inhibitors at discharge from the hospital reduced significantly the risk of death in the long-term period (RR=0.7.Conclusion. High rate of long-term mortality in the LIS-2 register can be largely explained by the poor quality of primary and secondary prevention of cardiovascular events.

To develop a method for the assessment of quality of medical prevention of recurrent stroke and its’ testing using the results of the LIS-2 register (Lyubertsy study of mortality in patients after stroke.Material and methods. The scale evaluation of the quality of therapy for the prevention of recurrent stroke developed in accordance with the modern clinical practice guidelines, as well as the recurrent stroke prevention index (RSPI for this assessment were elaborated. The analysis of the therapy was performed in patients after stroke in LIS-2 registers (n=219. The assessment of the quality of treatment was performed using RSPI, the influence of the index results on the in-hospital mortality was studied.Results. Two groups of patients [with RSPI=0 (n=137 and RSPI>0 (n=82] were formed on the basis of the results evaluation via RSPI. Significant differences between groups were not found. At the same time higher in-hospital mortality (p=0.014; χ2 Pearson was detected in patients with RSPI=0; relative risk of in-hospital death (after adjustment for sex and age was 2.04 [1.07-3.91] (p=0.031. Analysis of the length of survival and duration of hospital stay was performed in both groups using the Kaplan-Meier method. In-hospital mortality was significantly higher in patients with RSPI=0, which was confirmed by the log-rank test (p=0.032.Conclusion. The results of the quality of medical care assessment in accordance with the developed method are significantly related to the outcomes during the stay in a hospital. The developed method, based on current clinical recommendations, can serve as an example of the implementation of evidence-based medicine in actual practice.

  1. Professional communications of Russian technical and engineering specialists: empirical analysis

    2016-12-01

    Full Text Available Sociology of professions focus on the role of interpersonal and intergroup communications in the professional communities as an element of professional culture. The article considers forms and features of professional communications of Russian engineers and technicians in the context of their professional culture defined as the constellation of ideology, values, beliefs, language, and forms of activity typical for the community, which rarely becomes an object of Russian sociologists’ studies. The author shows that interpersonal professional communications on the various aspects of professional activity is an important element of professional culture. The article is based on the results of online survey of Russian engineers and expert interviews with Russian technical specialists - they were questioned on the ways of updating their professional knowledge and on the role of various channels of communication in this process. At the beginning of the article, the author provides an overview of approaches to the study of professional culture in Russia and abroad, and underlines the significant role of the Internet and the declining role of literature as a source of new knowledge for the engineering and technical staff. The results of the study also revealed an important role of informal and direct communications in the transfer of professional knowledge within the engineering community, while organizational environment has a relatively low impact on the updating of professional knowledge, which can be explained by the lack of management attention to the professional development of specialists.

  2. Restoring medical professionalism.

    Science.gov (United States)

    Bernat, James L

    2012-08-21

    The essence of medical professionalism is placing dedication to the welfare of patients above physicians' personal or proprietary interests. Medicine has become deprofessionalized as a consequence of socioeconomic factors leading to increasing commercialization and perverse financial incentives converting it into a business, the presence of unmanaged conflicts of interest, challenges to medical authority by insurance companies and the consumerism movement, and by gradual changes in the attitudes of physicians. Organized medicine has responded by making explicit its standards of professionalism and its dedication to preserving them. Medical educators have studied the means to develop professional attitudes and behaviors among medical students and residents. Modeling the characteristics of professional behavior by virtuous physicians remains the most effective method to instill professional behaviors in trainees. Restoring professionalism may be abetted by changes in physicians' financial incentives through innovative models of health care delivery, by physicians reducing their conflicts of interest, and by medical societies rejecting a guild identity.

  6. Professionalism: rise and fall.

    Science.gov (United States)

    Larson, M S

    1979-01-01

    Historically, the early professionalization movements in medicine and the law appear as organizational projects which aspire to monopolize income and opportunities in markets of services or labor and to monopolize status and work privileges in occupational hierarchies. Their central task is to standardize training and link it to actual or potential markets of labor or services, a linkage that is structurally effected in the modern university. The second wave of professionalization has different protagonists than the older "market professions": placed in a different structural situation, the bureaucratic professions transform the model of profession (which they adopt as a strategy of collective ascension) into an ideology. The import of the ideology of professionalism is examined in relation to two issues: the relationships between professional occupations and bureaucratic organizations; and the position of professional occupations within the larger structure of inequality. Analysis of the first point requires consideration of the distinctions between professional occupations in the public and private sectors, the use of professional knowledge and the image of profession in bureaucratic organizations, and the specific characteristics of professions that produce their own knowledge. In the discussion of the second point, professional occupations and their ideology are examined in relation to other occupations and to the possibilities of political awareness generated by uncertain professional statuses.

    2013-01-01

    Professional identity, or how a doctor thinks of himself or herself as a doctor, is considered to be as critical to medical education as the acquisition of skills and knowledge relevant to patient care. This article examines contemporary literature on the development of professional identity within medicine. Relevant theories of identity construction are explored and their application to medical education and pedagogical approaches to enhancing students' professional identity are proposed. The influence of communities of practice, role models, and narrative reflection within curricula are examined. Medical education needs to be responsive to changes in professional identity being generated from factors within medical student experiences and within contemporary society.

    2015-01-01

    The widespread use of digital media (both computing devices and the services they access) has blurred the boundaries between our personal and professional lives. Contemporary students are the last to remember a time before the widespread use of the Internet and they will be the first to practice in a largely e-health environment. This article explores concepts of digital professionalism and their place in contemporary medical education, and proposes a series of principles of digital professionalism to guide teaching, learning and practice in the healthcare professions. Despite the many risks and fears surrounding their use, digital media are not an intrinsic threat to medical professionalism. Professionals should maintain the capacity for deliberate, ethical, and accountable practice when using digital media. The authors describe a digital professionalism framework structured around concepts of proficiency, reputation, and responsibility. Digital professionalism can be integrated into medical education using strategies based on awareness, alignment, assessment, and accountability. These principles of digital professionalism provide a way for medical students and medical practitioners to embrace the positive aspects of digital media use while being mindful and deliberate in its use to avoid or minimize any negative consequences.

    Majone, G

    1984-01-01

    Many professionals prefer to work in nonprofit organizations, rather than in either for-profit or bureaucratic organizations. This preference suggests that nonprofits may be successful in reducing the tension between professional principles and institutional requirements. Professionals in for-profit organizations must submit to the control of a manager who is motivated to overrule them whenever their decisions come into conflict with the goal of profit maximization. Bureaucratic organizations stress predictability of results and adherence to rules as the overriding criteria of evaluation and control. This paper argues that nonprofits are on the whole superior from the point of view of professional ideology and practice. Thus, given a commitment to the values of professionalism, the preference for the nonprofit form becomes understandable, even without the usual assumptions about income-maximizing behavior.

    Professional development encompasses more than simply attending continuing education courses or returning to school for advanced degrees. It can also refer to looking up an unfamiliar diagnosis, changing your practice based on new evidence, and networking with peers about professional issues. Professional growth also involves having curiosity, wanting to provide the best possible care for your patients, and exuding excellence as a nurse. It is about investing in yourself! In doing so, you are not only growing as a professional but also promoting the image of nursing. Several national initiatives, such as Magnet and the Institute of Medicine's (IOM 's) Future of Nursing Report, are available to help improve and transform health care, and also to hopefully help motivate us.1 However, the impetus for professional development needs to come from within each individual nurse.

    Despite evidence that large professional networks afford a host of financial and professional benefits, people vary in how motivated they are to build such networks. To help explain this variance, the present article moves beyond a rational self-interest account to examine the possibility that identity shapes individuals' intentions to network. Study 1 established a positive association between viewing professional networking as identity-congruent and the tendency to prioritize strengthening and expanding one's professional network. Study 2 revealed that manipulating the salience of the self affects networking intentions, but only among those high in networking identity-congruence. Study 3 further established causality by experimentally manipulating identity-congruence to increase networking intentions. Study 4 examined whether identity or self-interest is a better predictor of networking intentions, providing support for the former. These findings indicate that identity influences the networks people develop. Implications for research on the self, identity-based motivation, and professional networking are discussed.

    It is traditionally assumed that licensure of healthcare professionals means that they are minimally competent. Many nursing specialty organizations offer examinations and other processes for certification, suggesting that certification is associated with continued competency. Can standardized examination for certification and continuing education for recertification ensure continued competency? Continuing education and testing provide a limited picture of an individual's knowledge and/or skill acquisition in a limited area at one point in time. However, portfolios promote critical thinking, self-assessment, and individual accountability. A portfolio is a portable mechanism for evaluating competencies that may otherwise be difficult to assess. This article summarizes some of the literature addressing portfolios, including aspects of portfolio development process, the value of portfolios versus continuing education for competency assessment, evidence associated with portfolio usage, and suggestions for organizing nursing portfolios.

    Full Text Available Introduction. We discuss the concept of core competencies applied to policies for teaching and training information professionals, particularly librarians. Method. Sixty graduates of the Institute were employed as information professionals. These sixty were asked to attribute degrees of importance to specific items associated with knowledge and skills that, within the scope of this research, were considered core competencies for meeting the demands of their jobs. Participants were also asked to cite knowledge they acquired in school and knowledge they use in exercising their profession, the skills that they consider necessary but that they did not gain in school, and the difficulties they encounter in exercising their profession and for which they were not sufficiently well prepared. Analysis. Both quantitative and qualitative data analyses were performed. The data were tabulated using Access and several reports and cross-tabulations were generated. Results. The results suggest a gulf between knowledge and skills acquired in library school and those that are required by the job market. In particular, participants lacked the skills they needed to work with information and communication technologies. Conclusion. The concept of core competencies is increasingly taken into account by the productive sector of the economy. The educational system ought to keep up with this change. The empirical research described shows that there is a need to establish advanced and modern policies for the education of librarians, participants in the market for information professionals.

Paper questionnaires were mailed to those selected. Michigan Library Association’s official policy barred the release of its membership list to researchers. Consequently, announcements of the survey were placed in three successive issues of the Association’s electronic newsletter. Interested members were directed to a website to complete an electronic version of the questionnaire. This option was also extended to members of the other three library associations. The overall research question was investigated through specific questions that sought to ascertain the overall level of interest in professional library and information studies (LIS education, levels of interest in specific types of programs, factors that favoured or deterred enrolment in doctoral programs, as well as the fields of study that were preferred for combination with LIS in doctoral programs. With the exception of demographic type questions (e.g., place of residence and educational qualifications and two questions that required open ended responses, the questionnaire design encompassed questions with Likert scale type responses. Analysis of the responses included descriptive statistics, the use of Pearson chi square to determine statistically significant relationships, and, to a lesser extent, content analysis.Main Results – A total of 270 questionnaires(33% were returned from three populations: Ohio, Indiana, and Ontario.

  2. Representations of the Concept of Trust in the Literature of Library and Information Studies

    Directory of Open Access Journals (Sweden)

    Dean Leith

    2013-11-01

    Full Text Available Governments and organizations around the world are increasingly turning to knowledge and information sharing as a lead strategy for developing response capacity to address issues in a wide range of programs and policy areas. The sharing of information and knowledge within organizations may be influenced by a range of factors, one being trust. This paper seeks, firstly, to identify and explore some key theoretic approaches to trust applied in the broader social sciences literature, including trust as a “leap of faith” or willingness to vulnerability; trust as a key component of social capital; and trust as a component of the concept of power-knowledge and truth- telling as found in the work of Michel Foucault. Second, the paper presents the findings of a meta-analysis conducted of recent library and information science (LIS literature in order to analyze how these three theoretical approaches are represented. Findings of the meta-analysis indicate that the trust definitions offered by two of the three theoretical perspectives investigated are well represented in recent LIS research; that other simpler definitions of trust are also represented; and that over one quarter of the sample were found to offer no explicit definition of trust. Analysis of these latter studies suggest that trust is represented by the implicit views and assumptions of researchers and the focus is more on the embedded authority of the information or abstract system rather than on the trustor as an essential component of the trust dynamic.

    2013-01-01

    Full Text Available Professionalism is a way of being which underlies all the responsibilities of a pharmacist and associated general and professional abilities. The Student Affairs Committee was charged with developing a college-wide professionalism plan to meet the Accreditation Council for Pharmacy Education (ACPE Standards 15.1 and 23. This plan was developed concurrently with a new curriculum. The plan was developed systematically with the following goals: 1 create a definition of professionalism, 2 determine outcomes of the plan, 3 identify existing components which should be continued and new components to be added, 4 ensure existing and new components are linked to outcomes and 5 develop a continuous assessment process for the plan. The proposed plan consists of curricular, co-curricular and extra-curricular activities designed to help students gain experience in three professionalism pillars: Competence, Connection and Character, as defined by Brown et al in “Taxonomy of Professionalism”. While knowledge and skills will be enhanced, the focus of development will be on student virtues, values and attitudes—that what they do defines who they are. The goal is to help students develop as people and professionals who value the high ideals expected of a pharmacist.

    Camerino, Donatella; Cassitto, Maria Grazia; Gugiari, Maria Chiara; Conway, P M

    2013-01-01

    Past clinical research has provided varied and sometimes diverging descriptions of burnout. As burnout is still prevalent in today's workplaces, actions are required mainly at the primary but also at the secondary and tertiary levels of prevention. In this literature review, the concept of burnout is reread through the lens of positive psychology and the most established theoretical models in the field. A common view is seemingly emerging that characterizes burnout as a condition of alienation, loss of motivation and low autonomy resulting from an unbridgeable gap in the personal and/or organizational resources that one has to invest in building a stimulating and rewarding professional career, full of significant relationships that give meaningfulness to one's life project. Establishing clinical criteria for burnout, as it is the case in some European countries, couldfacilitate the identification of the syndrome and the estimation of its prevalence in Italian work organizations.

  7. Professional practice among woman dentist.

    Science.gov (United States)

    Pallavi, S K; Rajkumar, G C

    2011-01-01

    This review aims to give an inside view of professional career of a women dentist, addresses the unique demands of being a woman dentist, and highlight ways to address these issues. The Medline database, scholarly literature, and informal literature were considered for this review. Working hours of female dentists do not differ significantly from the working hours of their male counterparts, until they have children. The female dentists' working hours showed a distinct drop as soon as they started a family. It was also found that women dentists are more likely to take career break. It is clear that childrearing and family responsibilities have a great impact on women's working life. Significant differences between males and females in work title and specialization were evident in an academic institution. Due to the societal orientation which regards women as primarily home makers, the responsibilities for family caretaking continues to fall disproportionately on women, and this fact could explain why women abandon their careers in the advanced stages. Efforts should be made to identify and reduce barriers to women's advancement in dentistry.

  9. Long-Life and High-Areal-Capacity Li-S Batteries Enabled by a Light-Weight Polar Host with Intrinsic Polysulfide Adsorption.

    Science.gov (United States)

    Pang, Quan; Nazar, Linda F

    2016-04-26

    Lithium-sulfur batteries are attractive electrochemical energy storage systems due to their high theoretical energy density and very high natural abundance of sulfur. However, practically, Li-S batteries suffer from short cycling life and low sulfur utilization, particularly in the case of high-sulfur-loaded cathodes. Here, we report on a light-weight nanoporous graphitic carbon nitride (high-surface-area g-C3N4) that enables a sulfur electrode with an ultralow long-term capacity fade rate of 0.04% per cycle over 1500 cycles at a practical C/2 rate. More importantly, it exhibits good high-sulfur-loading areal capacity (up to 3.5 mAh cm(-2)) with stable cell performance. We demonstrate the strong chemical interaction of g-C3N4 with polysulfides using a combination of spectroscopic experimental studies and first-principles calculations. The 53.5% concentration of accessible pyridinic nitrogen polysulfide adsorption sites is shown to be key for the greatly improved cycling performance compared to that of N-doped carbons.

    2015-12-01

    Despite recent advances in land surface modeling and remote sensing, estimates of the global water budget are still fairly uncertain. Uncertainties are particularly high in areas where data for model calibration and evaluation are scarce or unavailable. This study presents recent developments in the hydrological modeling over the Tigris-Euphrates River basin. An intercomparison effort is performed in order to determine how models and meteorological forcings represent physical processes. In this sense, multiple experiments are performed using state-of-the-art capabilities implemented in the NASA Land Information System (LIS). The NASA Modern Era Retrospective Reanalysis for Applications (MERRA) and Global Data Assimilation System (GDAS) meteorological datasets are used as main forcings. Additional experiments are performed replacing their precipitation with the Climate Hazards Group Infra-Red Precipitation with Stations (CHIRPS) dataset. Both Catchment and Noah land surface models coupled with the Hydrological Modeling and Analysis Platform (HyMAP) river routing scheme are considered to simulate the water budget and surface water dynamics. Due to the scarce ground-based data availability, satellite-based estimates of the terrestrial water storage, evapotranspiration, water level and floodplain extent are used as complimentary information to evaluate the hydrological behavior in the basin. In particular, the water shortage observed in 2015 in that region is analyzed based on model outputs. Finally, we discuss prospects and challenges in considering anthropogenic impacts (irrigation and dams) on the hydrological modeling of the basin.

    Tremendous efforts have been made to design the cathode of Li-S batteries to improve their energy density and cycling life. However, challenges remain in achieving fast electronic and ionic transport while accommodating the significant cathode volumetric change, especially for the cathode with a high practical mass loading. Here we report a cathode architecture, which is constructed by burning lithium foils in a CS2 vapour. The obtained structure features crystalline Li2S nanoparticles wrapped by few-layer graphene (Li2S@graphene nanocapsules). Because of the improvement on the volumetric efficiency for accommodating sulfur active species and electrical properties, the cathode design enables promising electrochemical performance. More notably, at a loading of 10 mgLi2S cm-2, the electrode exhibits a high reversible capacity of 1,160 mAh g-1s, namely, an area capacity of 8.1 mAh cm-2. Li2S@graphene cathode demonstrates a great potential for Li-ion batteries, where the Li2S@graphene-cathode//graphite-anode cell displays a high capacity of 730 mAh g-1s as well as stable cycle performance.

  12. Non-uniformly functionalized titanium carbide-based MXenes as an anchoring material for Li-S batteries: A first-principles calculation

    Science.gov (United States)

    Sim, Eun Seob; Chung, Yong-Chae

    2018-03-01

    In this study, the influence of the non-uniform surface of F- and O-functionalized Ti2C on the anchoring behavior of lithium polysulfide (LiPS) is investigated using density functional theory. In order to consider the non-uniform surface, the substitutional, vacancy, and S-trapped sites of F- and O-functionalized Ti2C are designed. The anchoring behavior is investigated considering the adsorption energy of LiPS, reactivity between Li atoms and the substrate, and the reduction state of the S atoms. On the F-substitutional site of the O-functionalized surface, it is confirmed that the suppressing mechanism changes from the neutralization of S atoms to the anchoring of LiPS. However, too strong of an interaction between Ti atoms exposed at the vacancy site and S atoms induces trapping of the S atom at the vacancies of both F- and O-functionalized surfaces. As a result of the trapping of the S atom, the use of active material decreases. In addition, the S-trapped site originated from the vacancy site does not affect the suppressing mechanism. In conclusion, to optimize the Ti2C-based MXene as an anchoring material for Li-S batteries, the preparation process should be focused on eliminating the vacancy of functional groups.

    Albarède, Francis

    The Public Library of Science Open Letter (http://www.publiclibraryofscience.org) is a very generous initiative, but, as most similar initiatives since the advent of electronic publishing, it misses the critical aspects of electronic publishing.Ten years ago, a Publisher would be in charge of running a system called a “scientific journal.” In such a system, the presence of an Editor and peer Reviewers secures the strength of the science and the rigor of writing; the Publisher guarantees the professional quality of printing, efficient dissemination, and long-term archiving. Publishing used to be in everyone's best interest, or nearly everyone. The Publisher, because he/she is financially motivated, ensures widespread dissemination of the journal amongst libraries and individual subscribers. The interest of the Author is that the system guarantees a broad potential readership. The interest of the Reader is that a line is drawn between professionally edited literature, presumably of better quality, and gray literature or home publishing, so that he/she does not waste time going through ‘low yield’ ungraded information. The Publisher could either be a private company, an academic institution, or a scholarly society. My experience is that, when page charges and subscription rates are compounded, journals published by scholarly societies are not necessarily cheaper. The difference between these cases is not the cost of running an office with rents, wages, printing, postage, advertisement, and archiving, but that a private Publisher pays shareholders. Shareholders have the bad habit of minding their own business and, therefore, they may interfere negatively with scientific publishing. Nevertheless, while the stranglehold imposed by private Publishers on our libraries over the last 10 years by increasing subscription rates may in part be due to shareholders' greed, this is true only in part. The increases are also a consequence of the booming number of pages being

Embora mantida fora de cogitação durante seus primeiros oitenta anos de existência, a questão da "elegibilidade feminina" não deixou de integrar a pauta de algumas das sessões acadêmicas. Destarte, o presente artigo objetiva iluminar este tema, tendo em vista os bastidores de dois importantes episódios ocorridos, respectivamente, em 1911 e 1930, quais sejam: a cogitação do nome da filóloga Carolina Michaëlis para integrar o quadro de sócios correspondentes da "Casa de Machado de Assis" e a proposta oficial de candidatura encaminhada por Amélia Beviláqua, primeira mulher a tentar concorrer a uma vaga entre os membros efetivos da agremiação.The Brazilian Academy of Letters emerged as an environment resistant to the presence of women. Although it was unthinkable during its first eighty years of existence, the question of "feminine eligibility" did make the agenda of some of the academic sessions.

  16. Spiritual Care Education of Health Care Professionals

    2015-05-01

    Full Text Available Nurses and health care professionals should have an active role in meeting the spiritual needs of patients in collaboration with the family and the chaplain. Literature criticizes the impaired holistic care because the spiritual dimension is often overlooked by health care professionals. This could be due to feelings of incompetence due to lack of education on spiritual care; lack of inter-professional education (IPE; work overload; lack of time; different cultures; lack of attention to personal spirituality; ethical issues and unwillingness to deliver spiritual care. Literature defines spiritual care as recognizing, respecting, and meeting patients’ spiritual needs; facilitating participation in religious rituals; communicating through listening and talking with clients; being with the patient by caring, supporting, and showing empathy; promoting a sense of well-being by helping them to find meaning and purpose in their illness and overall life; and referring them to other professionals, including the chaplain/pastor. This paper outlines the systematic mode of intra-professional theoretical education on spiritual care and its integration into their clinical practice; supported by role modeling. Examples will be given from the author’s creative and innovative ways of teaching spiritual care to undergraduate and post-graduate students. The essence of spiritual care is being in doing whereby personal spirituality and therapeutic use of self contribute towards effective holistic care. While taking into consideration the factors that may inhibit and enhance the delivery of spiritual care, recommendations are proposed to the education, clinical, and management sectors for further research and personal spirituality to ameliorate patient holistic care.

    ABSTRACT Health professionals have been identified as a high risk group for job-related stress and burnout. This study builds on the existing literature to examine the links between burnout and the development of professional values as well as the broad scope of occupational therapy, which may act as a hindrance to establishing a concise and well recognized professional identity.

The factors that contribute to the relationship between a lack of professional identity in the field of occupational therapy and the levels of burnout among occupational therapists are identified and implications for establishing a strong and healthy workforce in occupational therapy are discussed.
