Digital disruption is a term/phenomenon frequently appearing in innovation management literature. However, no academic consensus exists as to what it entails; conceptual nor theoretical. We use the SLR-method (Structured Literature Review) to investigate digital disruption literature. A SLR......-study conducted in 2017 revealed some useful information on how disruption and digital disruption literature has developed over a specific period. However, this study was less representative of papers addressing digital disruption; which is the in-depth subject of this paper. To accommodate this, we intend...... to conduct a similar SLR-study assembling a body literature having digital disruption as the only common denominator...

Youth Responses to School Shootings: a Review.

Travers, Áine; McDonagh, Tracey; Elklit, Ask

2018-05-19

This paper aims to synthesize research relating to youth responses to school shootings between 2014 and 2017. The main questions it addresses are how such events impact young people psychologically, and what risk or protective factors may contribute to different trajectories of recovery? Recent research suggests that most young people exposed to school shootings demonstrate resilience, exhibiting no long-term dysfunction. However, a minority will experience severe and chronic symptoms. The likelihood of experiencing clinically significant reactions is influenced by pre-trauma functioning as well as peri-traumatic and post-traumatic factors. These include proximity to the trauma, peri-traumatic dissociation, post-traumatic emotional regulation difficulties, social support, and flexibility of coping styles. Research that separates the distinguishing features of young people with differing recovery styles is vital to tailor intervention. But methodological and design issues associated with such research necessitates caution in drawing conclusions. Variation in definitions and measures and the self-report nature of many of the studies are potential sources of bias. Greater uniformity across designs would enhance confidence and allow for improved evidence-based intervention.

Re-Viewing Literature in Hermeneutic Research

Directory of Open Access Journals (Sweden)

Elizabeth Smythe PhD, RN, RM

2012-02-01

Full Text Available In academia there seems to be a taken for granted assumption that there is one way to do a literature review. This paper argues that the manner of reviewing literature needs to be congruent with the particular research methodology. As an example, the authors explicate reviewing literature in hermeneutic research. The paper begins by discussing philosophical assumptions. The authors then offer personal accounts of their experiences of working with literature in ways that are congruent with hermeneutic methodology. It is argued that the key purpose of exploring literature in hermeneutic research is to provide context and provoke thinking. Literature, which can include anything that provokes thinking on the phenomenon of interest, becomes an essential dialogical partner from which scholarly thinking and new insights emerge. In conclusion distinguishing hallmarks of ways of working hermeneutically with literature are articulated

Reviewing Literature in Bioethics Research: Increasing Rigour in Non-Systematic Reviews.

Science.gov (United States)

McDougall, Rosalind

2015-09-01

The recent interest in systematic review methods in bioethics has highlighted the need for greater transparency in all literature review processes undertaken in bioethics projects. In this article, I articulate features of a good bioethics literature review that does not aim to be systematic, but rather to capture and analyse the key ideas relevant to a research question. I call this a critical interpretive literature review. I begin by sketching and comparing three different types of literature review conducted in bioethics scholarship. Then, drawing on Dixon-Wood's concept of critical interpretive synthesis, I put forward six features of a good critical interpretive literature review in bioethics: answering a research question, capturing the key ideas relevant to the research question, analysing the literature as a whole, generating theory, not excluding papers based on rigid quality assessment criteria, and reporting the search strategy. © 2015 John Wiley & Sons Ltd.

Gray literature: An important resource in systematic reviews.

Science.gov (United States)

Paez, Arsenio

2017-08-01

Systematic reviews aide the analysis and dissemination of evidence, using rigorous and transparent methods to generate empirically attained answers to focused research questions. Identifying all evidence relevant to the research questions is an essential component, and challenge, of systematic reviews. Gray literature, or evidence not published in commercial publications, can make important contributions to a systematic review. Gray literature can include academic papers, including theses and dissertations, research and committee reports, government reports, conference papers, and ongoing research, among others. It may provide data not found within commercially published literature, providing an important forum for disseminating studies with null or negative results that might not otherwise be disseminated. Gray literature may thusly reduce publication bias, increase reviews' comprehensiveness and timeliness, and foster a balanced picture of available evidence. Gray literature's diverse formats and audiences can present a significant challenge in a systematic search for evidence. However, the benefits of including gray literature may far outweigh the cost in time and resource needed to search for it, and it is important for it to be included in a systematic review or review of evidence. A carefully thought out gray literature search strategy may be an invaluable component of a systematic review. This narrative review provides guidance about the benefits of including gray literature in a systematic review, and sources for searching through gray literature. An illustrative example of a search for evidence within gray literature sources is presented to highlight the potential contributions of such a search to a systematic review. Benefits and challenges of gray literature search methods are discussed, and recommendations made. © 2017 Chinese Cochrane Center, West China Hospital of Sichuan University and John Wiley & Sons Australia, Ltd.

:shoot ratio. Genotypes differ in seminal root anoxia tolerance, but mechanisms remain to be established; ethanol production rates do not explain anoxia tolerance. Root tip survival is short-term, and thereafter, seminal root re-growth upon re-aeration is limited. Genotypes differ in adventitious root numbers....... Although photosynthesis declines, sugars typically accumulate in shoots of waterlogged plants. Mn or Fe toxicity might occur in shoots of wheat on strongly acidic soils, but probably not more widely. Future breeding for waterlogging tolerance should focus on root internal aeration and better N...

Ginkgo, centrally placed in seed plant phylogeny, is considered important in many phylogenetic and evolutionary studies. Shoot dimorphism of Ginkgo has been long noted, but no work has yet been done to evaluate the relationships between overall branch architecture and wood ring characters, shoot growth, and environmental conditions. • Branches, sampled from similar canopy heights, were mapped with the age of each long shoot segment determined by counting annual leaf-scar series on its short shoots. Transverse sections were made for each long shoot segment and an adjacent short shoot; wood ring thickness, number of rings, and number of tracheids/ring were determined. Using branch maps, we identified wood rings for each long shoot segment to year and developmental context of each year (distal short shoot growth only vs. at least one distal long shoot). Climate data were also analyzed in conjunction with developmental context. • Significantly thicker wood rings occur in years with distal long shoot development. The likelihood that a branch produced long shoots in a given year was lower with higher maximum annual temperature. Annual maximum temperature was negatively correlated with ring thickness in microsporangiate trees only. Annual minimum temperatures were correlated differently with ring thickness of megasporangiate and microsporangiate trees, depending on the developmental context. There were no significant effects associated with precipitation. • Overall, developmental context alone predicts wood ring thickness about as well as models that include temperature. This suggests that although climatic factors may be strongly correlated with wood ring data among many gymnosperm taxa, at least for Ginkgo, correlations with climate data are primarily due to changes in proportions of shoot developmental types (LS vs. SS) across branches.

The ability to shoot an effective jump shot in the sport of basketball is critical to a player's success. In an attempt to better understand the aspects related to expert performance, researchers have investigated successful free throws and jump shots of various basketball players and identified movement variables that contribute to their success. The purpose of this study was to complete a systematic review of the scientific literature on the basketball free throw and jump shot for the purpose of revealing the critical components of shooting that coaches, teachers, and players should focus on when teaching, learning, practising, and performing a jump shot. The results of this review are presented in three sections: (a) variables that affect ball trajectory, (b) phases of the jump shot, and (c) additional variables that influence shooting.

Structure–Function Relationships in Highly Modified Shoots of Cactaceae

MAUSETH, JAMES D.

2006-01-01

• Background and Aims Cacti are extremely diverse structurally and ecologically, and so modified as to be intimidating to many biologists. Yet all have the same organization as most dicots, none differs fundamentally from Arabidopsis or other model plants. This review explains cactus shoot structure, discusses relationships between structure, ecology, development and evolution, and indicates areas where research on cacti is necessary to test general theories of morphogenesis. • Scope Cactus leaves are diverse; all cacti have foliage leaves; many intermediate stages in evolutionary reduction of leaves are still present; floral shoots often have large, complex leaves whereas vegetative shoots have microscopic leaves. Spines are modified bud scales, some secrete sugar as extra-floral nectaries. Many cacti have juvenile/adult phases in which the flowering adult phase (a cephalium) differs greatly from the juvenile; in some, one side of a shoot becomes adult, all other sides continue to grow as the juvenile phase. Flowers are inverted: the exterior of a cactus ‘flower’ is a hollow vegetative shoot with internodes, nodes, leaves and spines, whereas floral organs occur inside, with petals physically above stamens. Many cacti have cortical bundles vascularizing the cortex, however broad it evolves to be, thus keeping surface tissues alive. Great width results in great weight of weak parenchymatous shoots, correlated with reduced branching. Reduced numbers of shoot apices is compensated by great increases in number of meristematic cells within individual SAMs. Ribs and tubercles allow shoots to swell without tearing during wet seasons. Shoot epidermis and cortex cells live and function for decades then convert to cork cambium. Many modifications permit water storage within cactus wood itself, adjacent to vessels. PMID:16820405

Ferns: the missing link in shoot evolution and development

Directory of Open Access Journals (Sweden)

Andrew Robert George Plackett

2015-11-01

Full Text Available Shoot development in land plants is a remarkably complex process that gives rise to an extreme diversity of forms. Our current understanding of shoot developmental mechanisms comes almost entirely from studies of angiosperms (flowering plants, the most recently diverged plant lineage. Shoot development in angiosperms is based around a layered multicellular apical meristem that produces lateral organs and/or secondary meristems from populations of founder cells at its periphery. In contrast, non-seed plant shoots develop from either single apical initials or from a small population of morphologically distinct apical cells. Although developmental and molecular information is becoming available for non-flowering plants, such as the model moss Physcomitrella patens, making valid comparisons between highly divergent lineages is extremely challenging. As sister group to the seed plants, the monilophytes (ferns and relatives represent an excellent phylogenetic midpoint of comparison for unlocking the evolution of shoot developmental mechanisms, and recent technical advances have finally made transgenic analysis possible in the emerging model fern Ceratopteris richardii. This review compares and contrasts our current understanding of shoot development in different land plant lineages with the aim of highlighting the potential role that the fern C. richardii could play in shedding light on the evolution of underlying genetic regulatory mechanisms.

Langton, C.

2012-05-11

Concrete containment structures and cement-based fills and waste forms are used at the Savannah River Site to enhance the performance of shallow land disposal systems designed for containment of low-level radioactive waste. Understanding and measuring transport through cracked concrete is important for describing the initial condition of radioactive waste containment structures at the Savannah River Site (SRS) and for predicting performance of these structures over time. This report transmits the results of a literature review on transport through cracked concrete which was performed by Professor Jason Weiss, Purdue University per SRR0000678 (RFP-RQ00001029-WY). This review complements the NRC-sponsored literature review and assessment of factors relevant to performance of grouted systems for radioactive waste disposal. This review was performed by The Center for Nuclear Waste Regulatory Analyses, San Antonio, TX, and The University of Aberdeen, Aberdeen Scotland and was focused on tank closure. The objective of the literature review on transport through cracked concrete was to identify information in the open literature which can be applied to SRS transport models for cementitious containment structures, fills, and waste forms. In addition, the literature review was intended to: (1) Provide a framework for describing and classifying cracks in containment structures and cementitious materials used in radioactive waste disposal, (2) Document the state of knowledge and research related to transport through cracks in concrete for various exposure conditions, (3) Provide information or methodology for answering several specific questions related to cracking and transport in concrete, and (4) Provide information that can be used to design experiments on transport through cracked samples and actual structures.

Soil pollution at outdoor shooting ranges: Health effects, bioavailability and best management practices.

Science.gov (United States)

Fayiga, A O; Saha, U K

2016-09-01

The total lead (Pb) concentrations of the surface soil, sub surface soil, vegetation and surface waters of outdoor shooting ranges are extremely high and above regulatory limits. Lead is dangerous at high concentrations and can cause a variety of serious health problems. Shooters and range workers are exposed to lead dust and can even take Pb dust home to their families while some animals around the shooting range can ingest the Pb bullets. The toxicity of Pb depends on its bioavailability which has been determined to be influenced greatly by the geochemical properties of each site. The bioavailability of Pb in shooting ranges has been found to be higher than other metal contaminated soils probably because of its very low residual Pb (soil, migration of Pb within shooting ranges and offsite has been reported in literature. Best management practices to reduce mobility of Pb in shooting ranges involve an integrated Pb management program which has been described in the paper. The adoption of the non-toxic "green bullet" which has been developed to replace Pb bullets may reduce or prevent environmental pollution at shooting ranges. However, the contaminated soil resulting from decades of operation of several shooting ranges still needs to be restored to its natural state. Copyright © 2016 Elsevier Ltd. All rights reserved.

The group of passive prostheses consists of prosthetic hands and prosthetic tools. These can either be static or adjustable. Limited research and development on passive prostheses has been performed although many people use these prosthesis types. Although some publications describe passive prostheses, no recent review of the peer-reviewed literature on passive prostheses is available. Review the peer-reviewed literature on passive prostheses for replacement of the hand. Literature review. Four electronic databases were searched using a Boolean combination of relevant keywords. English-language articles relevant to the objective were selected. In all, 38 papers were included in the review. Publications on passive prosthetic hands describe their users, usage, functionality, and problems in activities of daily living. Publications on prosthetic tools mostly focus on sport, recreation, and vehicle driving. Passive hand prostheses receive little attention in prosthetic research and literature. Yet one out of three people with a limb deficiency uses this type of prosthesis. Literature indicates that passive prostheses can be improved on pulling and grasping functions. In the literature, ambiguous names are used for different types of passive prostheses. This causes confusion. We present a new and clear classification of passive prostheses. Clinical relevance This review provides information on the users of passive prosthetic hands and tools, their usage and the functionality. Passive prostheses receive very little attention and low appreciation in literature. Passive prosthetic hands and tools show to be useful to many unilateral amputees and should receive more attention and higher acceptance.

A set of photosynthetic responses of a Scots pine (Pinus sylvestris L.) shoot to light was derived from the shoot geometry and the photosynthetic response of a single needle. Computations showed that the shape of the photosynthesis light-curves varies substantially depending on the direction of radiation relative to the shoot position. Differences in the initial and maximum rates of photosynthesis were due to changes in the effective projection area and the irradiated fraction of the shoot, respectively

In this paper, we study how high school students reacted to the shocking news of a school shooting. The shooting coincided with national high-school matriculation exams. As there were exams both before and after the shooting, we can use a difference-in-differences analysis to uncover how the school shooting affected the test scores compared to previous years. We find that the average performance of young men declined due to the school shooting, whereas we do not observe a similar pattern for ...

Grounded theory research: literature reviewing and reflexivity.

Science.gov (United States)

McGhee, Gerry; Marland, Glenn R; Atkinson, Jacqueline

2007-11-01

This paper is a report of a discussion of the arguments surrounding the role of the initial literature review in grounded theory. Researchers new to grounded theory may find themselves confused about the literature review, something we ourselves experienced, pointing to the need for clarity about use of the literature in grounded theory to help guide others about to embark on similar research journeys. The arguments for and against the use of a substantial topic-related initial literature review in a grounded theory study are discussed, giving examples from our own studies. The use of theoretically sampled literature and the necessity for reflexivity are also discussed. Reflexivity is viewed as the explicit quest to limit researcher effects on the data by awareness of self, something seen as integral both to the process of data collection and the constant comparison method essential to grounded theory. A researcher who is close to the field may already be theoretically sensitized and familiar with the literature on the study topic. Use of literature or any other preknowledge should not prevent a grounded theory arising from the inductive-deductive interplay which is at the heart of this method. Reflexivity is needed to prevent prior knowledge distorting the researcher's perceptions of the data.

JOB SATISFACTION OF MIDWIVES: A LITERATURE REVIEW

Directory of Open Access Journals (Sweden)

Daniela Nedvědová

2017-05-01

Full Text Available Aim: The aims of the literature review were to identify and analyze factors affecting job satisfaction of midwives. Design: A literature review. Methods: Included in the literature review were full texts of papers published in English language from 1990 to 2014. The search for relevant data was performed using the electronic databases CINAHL, Medline, Science Direct and Wiley Online Library. From a total of 43 studies found, 11were analyzed as quantitative studies that fulfilled the specified criteria. Results: Job satisfaction of midwives is affected by a lack of support from the management of healthcare facilities, low salary, understaffing, insufficient time for professional activities, work-family imbalance, high workload, physical demands, inadequate professional development, working environment, stress and low autonomy at work. Midwives showed signs of exhaustion, fatigue, hostility and depression, contributing to job turnover. Conclusion: The literature review presents the factors influencing job satisfaction of midwives. This is affected by many variable determinants, which create a feeling of job satisfaction of midwives, but can also lead to job dissatisfaction and, consequently, high turnover. Keywords: midwives, job satisfaction.

2014-09-01

Full Text Available Instructors across the disciplines require their students to write literature reviews. Although numerous sources describe the literature review process, instructors and students face difficulty when approaching the structure of a literature review. This paper presents a straightforward, efficient approach for teaching students how to write a literature review. Developed over the course of three years at a university writing center, this lesson received substantial support from students across the disciplines. This paper reflects on one group of students’ experiences while writing literature reviews in a political science course, showing that students demonstrated a sense of confidence and direction after the lesson. University professors, writing center staff, and content-discipline instructors in higher education classrooms can alleviate their students’ anxiety about literature reviews by using this lesson in their classrooms.

The joy at birth: an interpretive hermeneutic literature review.

Science.gov (United States)

Crowther, Susan; Smythe, Elizabeth; Spence, Deb

2014-04-01

this literature review examines the experience of joy at birth and what that joy means. The premise is that the whole of the birthing experience has not been fully explicated in the literature and that something of significance remains unexplored and unspoken. It is argued that a hermeneutic phenomenological approach to reviewing literature provides unique insights and leads to deeper understandings about birth and the experience of joy that attunes at that moment. the philosophical underpinnings informed by Heidegger and Gadamer are central to this review and therefore the process of reviewing literature hermeneutically is described. Heideggerian phenomenology is used as the method to ask the questions of the literature in order that concealed and hidden experiences of joy at birth are made visible where they are gleaned from the literature. A hermeneutic lens is used to uncover relationships within the phenomenon of joy at birth and meaning. although a vast birth literature was reviewed joy at birth was often ignored, hidden or covered over. Reviewing the literature on relationships, professional presence, place of birth, birth satisfaction studies and birth as peak and spiritual experience provides glimpses of the phenomenon 'joy at birth'. it is argued that joy at birth remains largely neglected as a phenomenon worthy of consideration. Plausible interpretations are presented that suggest that joy at birth points to something significant and meaningful. Spiritual and sacred meaning is alluded to in the papers reviewed yet the majority of papers that investigate birth leave this meaning unspoken. The review highlights a need for further thinking and questioning about birth that would direct on-going investigation. Copyright © 2014 Elsevier Ltd. All rights reserved.

Violence and school shootings.

Science.gov (United States)

Flannery, Daniel J; Modzeleski, William; Kretschmar, Jeff M

2013-01-01

Multiple-homicide school shootings are rare events, but when they happen they significantly impact individuals, the school and the community. We focus on multiple-homicide incidents and identified mental health issues of shooters. To date, studies of school shootings have concluded that no reliable profile of a shooter exists, so risk should be assessed using comprehensive threat assessment protocols. Existing studies primarily utilize retrospective case histories or media accounts. The field requires more empirical and systematic research on all types of school shootings including single victim incidents, those that result in injury but not death and those that are successfully averted. We discuss current policies and practices related to school shootings and the role of mental health professionals in assessing risk and supporting surviving victims.

Adolescent mass shootings: developmental considerations in light of the Sandy Hook shooting.

Science.gov (United States)

Rice, Timothy R; Hoffman, Leon

2015-05-01

Adolescent mass shootings are a special subset of mass killings, which continue despite significant preventative public health efforts. It is often held that these individuals have few salient warning signs that could have been identified. This piece proposes that mass shootings committed by adolescent and post-adolescent young males must be understood from a developmental perspective. The hypothesis proposed in this paper is that such killings occur as the result of the adolescent's frustrated effort to progress along normative development. The goal of normative separation from maternal figures by the boy is presented as a potential risk factor when this goal is thwarted. Childhood case material from the perpetrator of a recent adolescent mass shooting, the Sandy Hook shooting, is discussed as an illustration of this hypothesis. Implications for public health measures and for individualized treatment are presented and developed.

Systematic review of the literature on simulation in nursing education.

Science.gov (United States)

Norman, Jamil

2012-01-01

Simulation-based learning is an educational intervention which creates an environment that is conducive to experiential learning. Despite the prevalence of research on the influence of simulation on nursing education, there is a dearth of literature on the effectiveness of simulation-based learning. This systematic review examines literature on simulation outcomes in nursing education from the years 2000-2010. The electronic databases reviewed for the systematic review of the literature included: CINAHL Plus, Medline, Health Source: Nursing/Academic Education, Google Scholar, and Digital Dissertations and Theses through ProQuest. The MeSH search terms included "simulation outcomes measurement" and "nursing education". Seventeen studies were included in the review of the literature. The literature was categorized into three themes; internal outcomes, external outcomes, and clinical evaluation. The available literature on simulation and nursing education provides evidence that that simulation is useful in creating a learning environment which contributes to knowledge, skills, safety, and confidence. This systematic review of the literature revealed a gap in the literature pertaining to the transfer of these outcomes to the clinical setting, and lays a foundation for further research on outcomes specific to simulation and nursing education.

Simulation Modelling in Healthcare: An Umbrella Review of Systematic Literature Reviews.

Science.gov (United States)

Salleh, Syed; Thokala, Praveen; Brennan, Alan; Hughes, Ruby; Booth, Andrew

2017-09-01

Numerous studies examine simulation modelling in healthcare. These studies present a bewildering array of simulation techniques and applications, making it challenging to characterise the literature. The aim of this paper is to provide an overview of the level of activity of simulation modelling in healthcare and the key themes. We performed an umbrella review of systematic literature reviews of simulation modelling in healthcare. Searches were conducted of academic databases (JSTOR, Scopus, PubMed, IEEE, SAGE, ACM, Wiley Online Library, ScienceDirect) and grey literature sources, enhanced by citation searches. The articles were included if they performed a systematic review of simulation modelling techniques in healthcare. After quality assessment of all included articles, data were extracted on numbers of studies included in each review, types of applications, techniques used for simulation modelling, data sources and simulation software. The search strategy yielded a total of 117 potential articles. Following sifting, 37 heterogeneous reviews were included. Most reviews achieved moderate quality rating on a modified AMSTAR (A Measurement Tool used to Assess systematic Reviews) checklist. All the review articles described the types of applications used for simulation modelling; 15 reviews described techniques used for simulation modelling; three reviews described data sources used for simulation modelling; and six reviews described software used for simulation modelling. The remaining reviews either did not report or did not provide enough detail for the data to be extracted. Simulation modelling techniques have been used for a wide range of applications in healthcare, with a variety of software tools and data sources. The number of reviews published in recent years suggest an increased interest in simulation modelling in healthcare.

A Framework for Rigorously Identifying Research Gaps in Qualitative Literature Reviews

Müller-Bloch, Christoph; Kranz, Johann

2015-01-01

Identifying research gaps is a fundamental goal of literature reviewing. While it is widely acknowledged that literature reviews should identify research gaps, there are no methodological guidelines for how to identify research gaps in qualitative literature reviews ensuring rigor and replicability....... Our study addresses this gap and proposes a framework that should help scholars in this endeavor without stifling creativity. To develop the framework we thoroughly analyze the state-of-the-art procedure of identifying research gaps in 40 recent literature reviews using a grounded theory approach....... Based on the data, we subsequently derive a framework for identifying research gaps in qualitative literature reviews and demonstrate its application with an example. Our results provide a modus operandi for identifying research gaps, thus enabling scholars to conduct literature reviews more rigorously...

In-vitro morphogenesis of corn (Zea mays L.) : I. Differentiation of multiple shoot clumps and somatic embryos from shoot tips.

Science.gov (United States)

Zhong, H; Srinivasan, C; Sticklen, M B

1992-07-01

In-vitro methods have been developed to regenerate clumps of multiple shoots and somatic embryos at high frequency from shoot tips of aseptically-grown seedlings as well as from shoot apices of precociously-germinated immature zygotic embryos of corn (Zea mays L.). About 500 shoots were produced from a shoot tip after eight weeks of culture (primary culture and one subculture of four weeks) in darkness on Murashige and Skoog basal medium (MS) supplemented with 500 mg/L casein hydrolysate (CH) and 9 μM N(6)-benzyladenine (BA). In this medium, shoots formed in shoot tips as tightly packed "multiple shoot clumps" (MSC), which were composed of some axillary shoots and many adventitious shoots. When the shoot tips were cultured on MS medium containing 500 mg/L CH, 9 μM BA and 2.25 μM 2,4-dichlorophenoxyacetic acid (2,4-D), most of the shoots in the clumps were adventitious in origin. Similar shoot tips cultured on MS medium containing 500 mg/L CH, 4.5 μM BA and 2.25 μM 2,4-D regenerated many somatic embryos within eight weeks of culture. Somatic embryos were produced either directly from the shoot apical meristems or from calli derived from the shoots apices. Both the MSC and the embryos produced normal shoots on MS medium containing 2.25 μM BA and 1.8 μM indole-3-butyric acid (IBA). These shoots were rooted on MS medium containing 3.6 μM IBA, and fertile corn plants were grown in the greenhouse. The sweet-corn genotype, Honey N Pearl, was used for the experiments described above, but shoot-tip cultures from all of 19 other corn genotypes tested also formed MSC on MS medium containing 500 mg/L CH and 9 μM BA.

Current perspectives on shoot branching regulation

Directory of Open Access Journals (Sweden)

Cunquan YUAN,Lin XI,Yaping KOU,Yu ZHAO,Liangjun ZHAO

2015-03-01

Full Text Available Shoot branching is regulated by the complex interactions among hormones, development, and environmental factors. Recent studies into the regulatory mecha-nisms of shoot branching have focused on strigolactones, which is a new area of investigation in shoot branching regulation. Elucidation of the function of the D53 gene has allowed exploration of detailed mechanisms of action of strigolactones in regulating shoot branching. In addition, the recent discovery that sucrose is key for axillary bud release has challenged the established auxin theory, in which auxin is the principal agent in the control of apical dominance. These developments increase our understan-ding of branching control and indicate that regulation of shoot branching involves a complex network. Here, we first summarize advances in the systematic regulatory network of plant shoot branching based on current information. Then we describe recent developments in the synthesis and signal transduction of strigolactones. Based on these considerations, we further summarize the plant shoot branching regulatory network, including long distance systemic signals and local gene activity mediated by strigolactones following perception of external envi-ronmental signals, such as shading, in order to provide a comprehensive overview of plant shoot branching.

Costa, Christine B; Hardan-Khalil, Kholoud; Gibbs, Kimberly

2017-12-01

The phenomenon of orthorexia nervosa (ON) has been noted by clinicians since 1996 and described in the scientific literature, and yet there is no formal recognition of ON as a psychiatric diagnosis. Review the latest available literature regarding diagnoses similarities, presentation uniqueness, assessment/assessment tools, and suggested treatments of ON. A literature search of four databases focusing on articles published between 2000 and 2016 was conducted to evaluate the status of the literature on Orthorexia. Among the 15 articles selected for this review, similarities with other psychiatric disorders emerged, confusion about use of assessment tools existed, and the lack of evidence based treatments for ON was pronounced. More research is needed to determine the prevalence of pathologically unhealthy, obsessive, "self-defined healthy," eating behaviors, and to determine if ON is a unique eating disorder or just a subset of another disorder.

Full Text Available Expatriation is a widely studied area of research in work and organizational psychology. After expatriates accomplish their missions in host countries, they return to their countries and this process is called repatriation. Adjustment constitutes a crucial part in repatriation research. In the present literature review, research about repatriation adjustment was reviewed with the aim of defining the whole picture in this phenomenon. Present research was classified on the basis of a theoretical model of repatriation adjustment. Basic frame consisted of antecedents, adjustment, outcomes as main variables and personal characteristics/coping strategies and organizational strategies as moderating variables.

Dimensions of Ideology. A Review of Social-Psychological Literature

Directory of Open Access Journals (Sweden)

Bojan Todosijević

2014-01-01

Full Text Available In social psychological literature, ideology is typically conceived as a relatively stable and organized set of general orientations that include interrelated attitudes grouped according to various sources of constraint, such as psychological disposition, general values, or ideological traditions. The paper reviews social-psychological literature on the organization of social attitudes. Research on this topic started nearly eight decades ago, inspired by the research on the structure of intellectual abilities. Since then, a large body of literature has been generated, which has not been systematically reviewed. Despite the long tradition, this literature has not resulted in proportional cumulative scientific development. The review should help improving this situation by listing the relevant studies, examining the research methodology and the main findings. The review ends with the critical summary of the man findings and methodological problems, and recommendations for the future research.

Making literature reviews more reliable through application of lessons from systematic reviews.

Science.gov (United States)

Haddaway, N R; Woodcock, P; Macura, B; Collins, A

2015-12-01

Review articles can provide valuable summaries of the ever-increasing volume of primary research in conservation biology. Where findings may influence important resource-allocation decisions in policy or practice, there is a need for a high degree of reliability when reviewing evidence. However, traditional literature reviews are susceptible to a number of biases during the identification, selection, and synthesis of included studies (e.g., publication bias, selection bias, and vote counting). Systematic reviews, pioneered in medicine and translated into conservation in 2006, address these issues through a strict methodology that aims to maximize transparency, objectivity, and repeatability. Systematic reviews will always be the gold standard for reliable synthesis of evidence. However, traditional literature reviews remain popular and will continue to be valuable where systematic reviews are not feasible. Where traditional reviews are used, lessons can be taken from systematic reviews and applied to traditional reviews in order to increase their reliability. Certain key aspects of systematic review methods that can be used in a context-specific manner in traditional reviews include focusing on mitigating bias; increasing transparency, consistency, and objectivity, and critically appraising the evidence and avoiding vote counting. In situations where conducting a full systematic review is not feasible, the proposed approach to reviewing evidence in a more systematic way can substantially improve the reliability of review findings, providing a time- and resource-efficient means of maximizing the value of traditional reviews. These methods are aimed particularly at those conducting literature reviews where systematic review is not feasible, for example, for graduate students, single reviewers, or small organizations. © 2015 Society for Conservation Biology.

Groundwater: A review of the 1989 literature

International Nuclear Information System (INIS)

Miller, C.T.; Mayer, A.S.

1990-01-01

This review was prepared under the auspices of the WPCF Research Committee of the annual Literature Review issue of the Journal; because of logistical reasons it could not be published in June. However, in view of the growing importance of the subject, the review is presented here as a supplement to the June Literature Review issue that has not been through the Journal peer review process. In this review, distinctions are made between single-, two-, and three-phase systems. Single-phase systems refer to groundwater systems subjected to saturated flow conditions, whereas the two- and three-phase systems include groundwater systems subjected to unsaturated flow conditions, or conditions influenced by immiscible organic fluids such as petroleum products. Within the single-, two-, and three-phase system categories, subdivisions are made between physical, chemical, or biological processes such as hydrodynamics, sorption/desorption, chemical reactions, and biodegradation. Specialized areas such as radon and radionuclide transport, facilitated transport, and saline groundwaters also are treated separately. Rounding out this year's review, papers concerning groundwater quality monitoring, remediation, and management are discussed

Chen, Charlene Y.; Purdie-Vaughns, Valerie; Phelan, Jo C.; Yu, Gary; Yang, Lawrence H.

2015-01-01

The Virginia Tech and Columbine High shootings are 2 of the deadliest school massacres in the United States. The present study investigates in a nationally representative sample how White Americans’ causal attributions of these shooting moderate their attitudes toward the shooter’s race. White Americans shown a vignette based on the Virginia Tech shooting were more likely to espouse negative beliefs about Korean American men and distance themselves from this group the more they believed that the shooter’s race caused the shooting. Among those who were shown a vignette based on the Columbine High shooting, believing that mental illness caused the shooting was associated with weaker negative beliefs about White American men. White Americans in a third condition who were given the Virginia Tech vignette and prompted to subtype the shooter according to his race were less likely to possess negative beliefs about Korean American men the more they believed that mental illness caused the shooting. There was no evidence for the ultimate attribution error. Theoretical accounts based on the stereotype and in-group-out-group bias literature are presented. The current findings have important implications for media depictions of minority group behavior and intergroup relations. PMID:25198415

The design management provides the services with interesting solutions such as Benchmarking, CRM, Lean Approach, ServiceBlueprinting, continued education, among others. Literature review is an important tool to identify problems and respective solutions. However, considering the small number of studies approaching management of radiology services, this is a great field of research for the development of deeper studies.

Tire Crumb Research Study Literature Review / Gap ...

Science.gov (United States)

In order to more fully understand data gaps in human exposure and toxicity to tire crumb materials, ATSDR, CPSC and EPA undertook a collaborative effort in the form of a scientific literature review and subsequent gaps analysis. The first objective of the Literature Review and Gap Analysis (LRGA) collaboration was to identify the existing body of literature related specifically to human exposure to tire crumb materials through the use of synthetic turf athletic fields and playgrounds. The second objective was to characterize and summarize the relevant data from the scientific literature. The final objective was to review the summary information and identify data gaps to build on the current understanding of the state-of-the-science and inform the development of specific research efforts that would be most impactful in the near-term. Because of the need for additional information, the U.S. Environmental Protection Agency (EPA), the Centers for Disease Control and Prevention/Agency for Toxic Substances and Disease Registry (ATSDR), and the U.S. Consumer Product Safety Commission (CPSC) launched a multi-agency action plan to study key environmental human health questions. The Federal Research Action Plan includes numerous activities, including research studies (U.S. EPA, 2016). A key objective of the Action Plan is to identify key knowledge gaps.

Increasingly, health policy decision-makers and professionals are turning to research-based evidence to support decisions about policy and practice. Systematic reviews are useful for gathering, summarizing, and synthesizing published and unpublished research about clearly defined interventions. State-of-the-evidence reviews are broader than traditional systematic reviews and may include not only published and unpublished research, but also published and unpublished non-research literature. Decisions about whether to include this "grey literature" in a review are challenging and lead to many questions about whether the advantages outweigh the challenges. The primary purpose of this article is to describe what constitutes grey literature, and methods to locate it and assess its quality. The secondary purpose is to discuss the core issues to consider when making decisions to include grey literature in a state-of-the-evidence review. A recent state-of-the-evidence review is used as an exemplar to present advantages and challenges related to including grey literature in a review. Despite the challenges, in the exemplar, inclusion of grey literature was useful to validate the results of a research-based literature search. Decisions about whether to include grey literature in a state-of-the-evidence review are complex. A checklist to assist in decision-making was created as a tool to assist the researcher in determining whether it is advantageous to include grey literature in a review.

Raspberry bushy dwarf virus (RBDV) can be efficiently eradicated from raspberry plants (Rubus idaeus) by a procedure combining thermotherapy and cryotherapy. However, the bottleneck of this procedure is that, following thermotherapy, cryopreserved shoot tips become chlorotic during regrowth and eventually die after several subcultures. In addition, survival of heat-treated stock shoots and recovery of cryopreserved shoot tips following thermotherapy are low. The present study focused towards improving regrowth of cryopreserved raspberry shoot tips following thermotherapy. Results showed that preconditioning stock shoots with salicylic acid (SA; 0.01-0.1 mM) markedly increased survival of stock shoots after 4 weeks of thermotherapy. Regrowth of cryopreserved shoot tips following thermotherapy was also significantly enhanced when SA (0.05-0.1 mM) was used for preconditioning stock shoots. Addition of either Fe-ethylenediaminetetracetic acid (Fe-EDTA, 50 mg per L) or Fe-ethylenediaminedi(o)hydroxyphenylacetic acid (Fe-EDDHA, 50 mg per L) to post-culture medium strongly promoted regrowth and totally prevented chlorosis of shoots regenerated from cryopreserved shoot tips following thermotherapy. Using the parameters optimized in the present study, about 80 percent survival of heat-treated stock shoots and about 33 percent regrowth of cryopreserved shoot tips following thermotherapy were obtained. Morphology of plants regenerated from cryopreserved shoot tips following thermotherapy was identical to that of control plants, based on observations of leaf shape and size, internode length and plant height. Optimization of the thermotherapy procedure followed by cryotherapy will facilitate the wider application of this technique to eliminate viruses which can invade meristems.

High Frequency Multiple Shoot Induction of Curculigo orchioides Gaertn.: Shoot Tip V/S Rhizome Disc

Full Text Available Curculigo orchioides Gaertn. is an endangered medicinal plant with anticancer properties. The rhizome and tuberous roots of the plant have been used extensively in India in indigenous medicine. Due to its multiple uses, the demand for Curculigo orchioides is constantly on the rise; however, the supply is rather erratic and inadequate. Destructive harvesting, combined with habitat destruction in the form of deforestation has aggravated the problem. The plant is now considered ‘endangered’ in its natural habitat. Therefore, the need for conservation of this plant is crucial. Here, we describe a successful protocol for multiple shoot induction of C. orchioides using shoot tip and rhizome disc. We find that proximal rhizome discs are optimal for high frequency shoot bud formation than shoot tip and distal rhizome disc. We observed a synergistic effect between 6-benzylaminopurine (BAP and kinetin (KN (each at 1 mg/L on the regeneration of shoot buds from proximal rhizome disc than shoot tip explant. Optimum root induction was achieved on half-strength MS liquid medium supplemented with 1 mg/L of indole-3-butyric acid (IBA. The in vitro raised plantlets were acclimatized in green house and successfully transplanted to natural condition with 90% survival.

Full Text Available Plagiarism has repeatedly occurred in Indonesia, resulting in focusing on such academic misbehavior as a “central issue” in Indonesian higher education. One of the issues of addressing plagiarism in higher education is that there is a confusion of defining plagiarism. It seems that Indonesian academics had different perception when defining plagiarism. This article aims at exploring the issue of plagiarism by helping define plagiarism to address confusion among Indonesian academics. This article applies literature review by firs finding relevant articles after identifying databases for literature searching. After the collection of required articles for review, the articles were synthesized before presenting the findings. This study has explored the definition of plagiarism in the context of higher education. This research found that plagiarism is defined in the relation of criminal acts. The huge numbers of discursive features used position plagiaristic acts as an illegal deed. This study also found that cultural backgrounds and exposure to plagiarism were influential in defining plagiarism.

Whitley, Deborah R

2016-02-01

Unplanned hospital readmissions after the administration of general anesthesia for ambulatory procedures may contribute to loss of reimbursement and assessment of financial penalties. Pediatric patients represent a unique anesthetic risk. The purpose of this integrative literature review was to ascertain specific criteria used to evaluate discharge readiness for pediatric patients after anesthesia. This study is an integrative review of literature. An integrative literature search was conducted and included literature sources dated January 2008 to November 2013. Key words included pediatric, anesthesia, discharge, criteria, standards, assessment, recovery, postoperative, postanesthesia, scale, score, outpatient, and ambulatory. Eleven literature sources that contributed significantly to the research question were identified. Levels of evidence included three systematic reviews, one randomized controlled trial, three cohort studies, two case series, and two expert opinions. This integrative literature review revealed evidence-based discharge criteria endorsing home readiness for postanesthesia pediatric patients should incorporate consideration for physiological baselines, professional judgment with regard to infant consciousness, and professional practice standards/guidelines. Additionally, identifying and ensuring discharge to a competent adult was considered imperative. Nurses should be aware that frequently used anesthesia scoring systems originated in the 1970s, and this review was unable to locate current literature examining the reliability and validity of their use in conjunction with modern anesthesia-related health care practices.

Burgert, James M

2016-01-01

The intraosseous (IO) route of vascular access has been increasingly used to administer resuscitative fluids and drugs to patients in whom reliable intravenous (IV) access could not be rapidly or easily obtained. It is unknown that to what extent the IO route has been used to gain vascular access during disasters and mass casualty events. The purpose of this review was to examine the existing literature to answer the research question, "What is the utility of the IO route compared to other routes for establishing vascular access in patients resulting from disasters and mass casualty events?" Keyword-based online database search of PubMed, CINAHL, and the Cochrane Database of Systematic Reviews. University-based academic research cell. Included evidence were randomized and nonrandomized trials, systematic reviews with and without meta-analysis, case series, and case reports. Excluded evidence included narrative reviews and expert opinion. Not applicable. Of 297 evidence sources located, 22 met inclusion criteria. Located evidence was organized into four categories including chemical agent poisoning, IO placement, while wearing chemical protective clothing (PPE), military trauma, and infectious disease outbreak. Evidence indicates that the IO route of infusion is pharmacokinetically equal to the IV route and superior to the intramuscular (IM) and endotracheal routes for the administration of antidotal drugs in animal models of chemical agent poisoning while wearing full chemical PPE. The IO route is superior to the IM route for antidote administration during hypovolemic shock. Civilian casualties of explosive attacks and mass shootings would likely benefit from expanded use of the IO route and military resuscitation strategies. The IO route is useful for fluid resuscitation in the management of diarrheal and hemorrhagic infectious disease outbreaks.

The U.S. Fish and Wildlife Service National Conservation Training Center requested a literature review product that would serve as a resource to natural resource professionals interested in using webcams to connect people with nature. The literature review focused on the effects on the public of viewing wildlife through webcams and on information regarding installation and use of webcams. We searched the peer reviewed, published literature for three topics: wildlife cameras, virtual tourism, and technological nature. Very few publications directly addressed the effect of viewing wildlife webcams. The review of information on installation and use of cameras yielded information about many aspects of the use of remote photography, but not much specifically regarding webcams. Aspects of wildlife camera use covered in the literature review include: camera options, image retrieval, system maintenance and monitoring, time to assemble, power source, light source, camera mount, frequency of image recording, consequences for animals, and equipment security. Webcam technology is relatively new and more publication regarding the use of the technology is needed. Future research should specifically study the effect that viewing wildlife through webcams has on the viewers' conservation attitudes, behaviors, and sense of connectedness to nature.

2015-04-01

The Virginia Tech and Columbine High shootings are 2 of the deadliest school massacres in the United States. The present study investigates in a nationally representative sample how White Americans' causal attributions of these shooting moderate their attitudes toward the shooter's race. White Americans shown a vignette based on the Virginia Tech shooting were more likely to espouse negative beliefs about Korean American men and distance themselves from this group the more they believed that the shooter's race caused the shooting. Among those who were shown a vignette based on the Columbine High shooting, believing that mental illness caused the shooting was associated with weaker negative beliefs about White American men. White Americans in a third condition who were given the Virginia Tech vignette and prompted to subtype the shooter according to his race were less likely to possess negative beliefs about Korean American men the more they believed that mental illness caused the shooting. There was no evidence for the ultimate attribution error. Theoretical accounts based on the stereotype and in-group-out-group bias literature are presented. The current findings have important implications for media depictions of minority group behavior and intergroup relations. (c) 2015 APA, all rights reserved).

Mental health recovery: A review of the peer-reviewed published literature.

Science.gov (United States)

Jacob, Sini; Munro, Ian; Taylor, Beverley Joan; Griffiths, Debra

The concept of mental health recovery promotes collaborative partnership among consumers, carers and service providers. However views on mental health recovery are less explored among carers and service providers. The aim of this review was to analyse contemporary literature exploring views of mental health consumers, carers and service providers in relation to their understanding of the meaning of mental health recovery and factors influencing mental health recovery. The literature review questions were: How is mental health recovery and factors influencing mental health recovery viewed by consumers, carers and service providers? What are the differences and similarities in those perceptions? How can the outcomes and recommendations inform the Australian mental health practices? A review of the literature used selected electronic databases and specific search terms and supplemented with manual searching. Twenty-six studies were selected for review which included qualitative, mixed method, and quantitative approaches and a Delphi study. The findings indicated that the concept of mental health recovery is more explored among consumers and is seldom explored among carers and service providers. The studies suggested that recovery from mental illness is a multidimensional process and the concept cannot be defined in rigid terms. In order to achieve the best possible care, the stakeholders require flexible attitudes and openness to embrace the philosophy.

Gastric cancer screening, literature review

Porras Alfaro, Erika

2014-01-01

A comprehensive literature review was made of the methods of screening (pepsinogen test, gastrin-17, anti HP, SGD and Endoscopy). The review and descriptive study of the scientific literature related to the subject was conducted in the scientific databases: Pud Med, MD Consult and Medscape, from August 2013 to March 2014. 65 articles were found related to the topic. The review has included 47 items, assigned according to the criteria of inclusion and exclusion. Available methods were defined of high cost, difficult to spread, little sensitive, little specific and invasive. Endoscopy has had limitations of cost, quality, morbidity, mortality and availability. Pepsinogen tests and helicobacter pylori have helped identify the population at risk for later sift with endoscopy; but it is a very sensitive method. Endoscopy is recommended every two years in the population at risk (patients between 50 and 70 years with a family history of gastric cancer, chronic atrophic gastritis, Helicobacter pylori infection, intestinal metaplasia and dysplasia, patients with symptomatology of dyspepsia and with positive pepsinogen test) is a higher method than SGD in cost, sensitivity and specificity similar to invasive level. The training of the endoscopists should be strengthened in early gastric cancer detection since the detection depends on the quality of endoscopy [es

Accurate inference of shoot biomass from high-throughput images of cereal plants

Directory of Open Access Journals (Sweden)

Tester Mark

2011-02-01

Full Text Available Abstract With the establishment of advanced technology facilities for high throughput plant phenotyping, the problem of estimating plant biomass of individual plants from their two dimensional images is becoming increasingly important. The approach predominantly cited in literature is to estimate the biomass of a plant as a linear function of the projected shoot area of plants in the images. However, the estimation error from this model, which is solely a function of projected shoot area, is large, prohibiting accurate estimation of the biomass of plants, particularly for the salt-stressed plants. In this paper, we propose a method based on plant specific weight for improving the accuracy of the linear model and reducing the estimation bias (the difference between actual shoot dry weight and the value of the shoot dry weight estimated with a predictive model. For the proposed method in this study, we modeled the plant shoot dry weight as a function of plant area and plant age. The data used for developing our model and comparing the results with the linear model were collected from a completely randomized block design experiment. A total of 320 plants from two bread wheat varieties were grown in a supported hydroponics system in a greenhouse. The plants were exposed to two levels of hydroponic salt treatments (NaCl at 0 and 100 mM for 6 weeks. Five harvests were carried out. Each time 64 randomly selected plants were imaged and then harvested to measure the shoot fresh weight and shoot dry weight. The results of statistical analysis showed that with our proposed method, most of the observed variance can be explained, and moreover only a small difference between actual and estimated shoot dry weight was obtained. The low estimation bias indicates that our proposed method can be used to estimate biomass of individual plants regardless of what variety the plant is and what salt treatment has been applied. We validated this model on an independent

Hardeman, Rachel R; Murphy, Katy A; Karbeah, J'Mag; Kozhimannil, Katy Backes

Although a range of factors shapes health and well-being, institutionalized racism (societal allocation of privilege based on race) plays an important role in generating inequities by race. The goal of this analysis was to review the contemporary peer-reviewed public health literature from 2002-2015 to determine whether the concept of institutionalized racism was named (ie, explicitly mentioned) and whether it was a core concept in the article. We used a systematic literature review methodology to find articles from the top 50 highest-impact journals in each of 6 categories (249 journals in total) that most closely represented the public health field, were published during 2002-2015, were US focused, were indexed in PubMed/MEDLINE and/or Ovid/MEDLINE, and mentioned terms relating to institutionalized racism in their titles or abstracts. We analyzed the content of these articles for the use of related terms and concepts. We found only 25 articles that named institutionalized racism in the title or abstract among all articles published in the public health literature during 2002-2015 in the 50 highest-impact journals and 6 categories representing the public health field in the United States. Institutionalized racism was a core concept in 16 of the 25 articles. Although institutionalized racism is recognized as a fundamental cause of health inequities, it was not often explicitly named in the titles or abstracts of articles published in the public health literature during 2002-2015. Our results highlight the need to explicitly name institutionalized racism in articles in the public health literature and to make it a central concept in inequities research. More public health research on institutionalized racism could help efforts to overcome its substantial, longstanding effects on health and well-being.

To establish how common and impactful nursing and healthcare ageism is and whether proven interventions or prevention methods exist. Ageism has been a concern since 1969 when it was first introduced as a concept for social reform. As ageism has been linked to lower quality health services and reduced health care access, it is imperative that healthcare and nursing ageism is prevented or identified and reduced or eliminated. A qualitative narrative review of published research literature reviews using a scoping design to map all published reviews was undertaken. The EBSCO Discovery Service (providing access to articles in 271 databases, including MEDLINE and CINAHL) and Directory of Open Access Journals (providing access to over 9,000 open access journals) were used to find review articles. Using predetermined inclusion and exclusion criteria, and limited by English language and peer-review publications, 12 eligible reviews were identified and information from them was systematically identified, assessed and synthesised. The 12 reviews did not provide clear and convincing information to determine how common and impactful nursing or healthcare ageism is, nor what can best be done to prevent or address it. Although each review had value since research literature was collected and discussed on nursing or healthcare ageism, the array of literature search and analysis methods, and diversity in conclusions reached about the evidence is highly problematic. Research literature reviews offering a more balanced perspective and demonstrating greater care in finding and using quality evidence are needed. At this point in time, there is no clear understanding of how widespread and impactful nursing or healthcare ageism is, and what can best be done to prevent or address it. Nurses need to be aware that ageism may be common and impactful, and guard against it. © 2017 John Wiley & Sons Ltd.

Review Of Plutonium Oxidation Literature

International Nuclear Information System (INIS)

Korinko, P.

2009-01-01

A brief review of plutonium oxidation literature was conducted. The purpose of the review was to ascertain the effect of oxidation conditions on oxide morphology to support the design and operation of the PDCF direct metal oxidation (DMO) furnace. The interest in the review was due to a new furnace design that resulted in oxide characteristics that are different than those of the original furnace. Very little of the published literature is directly relevant to the DMO furnace operation, which makes assimilation of the literature data with operating conditions and data a convoluted task. The oxidation behavior can be distilled into three regimes, a low temperature regime (RT to 350 C) with a relatively slow oxidation rate that is influenced by moisture, a moderate temperature regime (350-450 C) that is temperature dependent and relies on more or less conventional oxidation growth of a partially protective oxide scale, and high temperature oxidation (> 500 C) where the metal autocatalytically combusts and oxidizes. The particle sizes obtained from these three regimes vary with the finest being from the lowest temperature. It is surmised that the slow growth rate permits significant stress levels to be achieved that help break up the oxides. The intermediate temperatures result in a fairly compact scale that is partially protective and that grows to critical thickness prior to fracturing. The growth rate in this regime may be parabolic or paralinear, depending on the oxidation time and consequently the oxide thickness. The high temperature oxidation is invariant in quiescent or nearly quiescent conditions due to gas blanketing while it accelerates with temperature under flowing conditions. The oxide morphology will generally consist of fine particles ( 250 (micro)m). The particle size ratio is expected to be < 5%, 25%, and 70% for fine, medium and large particles, respectively, for metal temperatures in the 500-600 C range.

The employment of Peer Support Workers, who themselves have experience of significant emotional distress, can promote recovery at an individual and organisational level. While research examining the benefits of peer support within mental health services continues to grow, an understanding of how, and through what processes, these benefits are reached remains under-developed. To review the published research literature relating to the process of peer support and its underpinning mechanisms to better understand how and why it works. A scoping review of published literature identified studies relating to peer support mechanisms, processes and relationships. Studies were summarised and findings analysed. Five mechanisms were found to underpin peer support relationships (lived experience, love labour, the liminal position of the peer worker, strengths-focussed social and practical support, and the helper role). The identified mechanisms can underpin both the success and difficulties associated with peer support relationships. Further research should review a broader range of literature and clarify how these mechanisms contribute to peer support in different contexts.

2014-11-01

Full Text Available Globally, virtual teams (VT as ICT-enabled emergent network organisation forms have gained international validity by innovative organisations, with a corresponding surge of interest in understanding how organisations can leverage VT to create business value. Despite growing deliberations in VT literature on managing VT, tasks and outcomes, however, creating business value through VT remains an unresolved theoretical and pragmatic conundrum. A review of prior relevant literature is essential to advancing knowledge. The paucity of published review articles seems to have impeded the field’s accumulation of VT knowledge. This research, therefore, reviews the current literature on case studies of VT to address the question: What are organisational challenges in creating business value through VT in the organisation? The key challenges found in the literature are effective communication, knowledge sharing, trust, and interpersonal skills in the new virtual boundary-less environment. Drawing on the IT business value model, we also discuss their resource-based implications.

Dobrohotoff, John T; Llewellyn-Jones, Robert H

2011-03-01

In many parts of the world the provision of psychogeriatric inpatient units (PGUs) remains limited. More units will be required over coming decades given rapid population aging. Medline (1950-2010), psycINFO (1806-2009), EMBASE (1980-2009) and CINAHL (1982-2009) were searched for papers about PGU design. Selected non-peer reviewed literature such as government reports and unpublished academic dissertations were also reviewed. Data were also obtained from the literature related to general adult psychiatry inpatient units where there was limited information from studies of units designed for older people. Over 200 papers were reviewed and 130 were included. There are few good quality studies to guide the design of acute PGUs and much of the existing literature is based on opinion and anecdote or, at best, based on observational studies. Randomized controlled studies comparing different designs and assessing outcomes are virtually non-existent. Several studies have identified violence and trauma resulting from hospitalization as significant problems with current acute PGU care. Despite its limitations the available literature provides useful guidance on how PGU design can optimize patient and staff safety and improve clinical outcomes. There are significant problems with current acute PGUs, and patient mix on existing units is an important issue. Future research should examine patient and staff perceptions of different PGU ward environments, the relationship between ward design and clinical outcomes, the effects of segregating patients with challenging behaviors in dementia and the benefits or otherwise of gender segregation.

Status of Electricity Act, 2003: A systematic review of literature

International Nuclear Information System (INIS)

Mukherjee, Shilpi; Dhingra, Tarun; Sengupta, Anirban

2017-01-01

The Electricity Act 2003 was a landmark Act which promised to remove the maladies which afflict the Indian Power Sector and that too at a time when the sector was ridden with problems. With concepts such as open access, multiple distribution licensees, wheeling of electricity etc, the said Act intended to encourage competition which in turn was meant bring a paradigm shift in the sector. The paper undertakes a systematic literature review to find the status of review of the promising Act. More than a decade has passed since its enactment and amendments are due with the legislative body of India but none of the literature reviewed gives a comprehensive view encompassing all the objectives of the Act. Moreover, these documents study either the probable impact or the impact on a particular segment only. It has important implications for the Power sector which highlights a significant gap in literature and provides a basis on which future research can be built upon. - Highlights: • Electricity Act 2003 is a landmark in Indian power sector reform. • Systematic literature review is done to find the status of review of the Act. • Status of Electricity Act 2003 not comprehensively reviewed. • Status of the act needs to be reviewed comprehensively through actual data.

This paper presents the results of a review of literature relating to knowledge transfer and exchange in healthcare. Treatment, planning and policy decisions in contemporary nursing and healthcare should be based on sound evidence wherever possible, but research knowledge remains generally underused. Knowledge transfer and exchange initiatives aim to facilitate the accessibility, application and production of evidence and may provide solutions to this challenge. This review was conducted to help inform the design and implementation of knowledge transfer and exchange activities for a large healthcare organization. Databases: ASSIA, Business Source Premier, CINAHL, PsychInfo, Medline and the Cochrane Database of Systematic Reviews. An integrative literature review was carried out including an extensive literature search. English language systematic reviews, literature reviews, primary quantitative and qualitative papers and grey literature of high relevance evaluating, describing or discussing knowledge transfer or exchange activities in healthcare were included for review (January 1990-September 2009). Thirty-three papers were reviewed (four systematic reviews, nine literature reviews, one environmental scan, nine empirical studies and ten case studies). Robust research into knowledge transfer and exchange in healthcare is limited. Analysis of a wide range of evidence indicates a number of commonly featured characteristics but further evaluation of these activities would benefit their application in facilitating evidence-based practice in nursing. © 2011 The Authors.

What's stopping a career in gerontological nursing?: literature review.

Science.gov (United States)

Neville, Christine; Dickie, Robyn; Goetz, Sandra

2014-01-01

Despite the rapid aging of the world's population, many countries are experiencing difficulty in recruiting nurses to work with older people. A literature review was conducted regarding the career preferences of undergraduate nursing students from seven different countries. The literature review has identified that gerontological nursing does not feature highly as a career goal. Notably, this has been the situation for the past decade. There is no indication that the situation is going to change at any time in the future unless some serious decisions are made at professional, health service, community, and government levels. This literature review has identified the reasons why undergraduate nurses are not choosing gerontological nursing as a career, what has been done in an attempt to address the problem, and what else may be done.

Conducting systematic reviews of intervention questions I: Writing the review protocol, formulating the question and searching the literature.

Science.gov (United States)

O'Connor, A M; Anderson, K M; Goodell, C K; Sargeant, J M

2014-06-01

This article is the fourth of six articles addressing systematic reviews in animal agriculture and veterinary medicine. Previous articles in the series have introduced systematic reviews, discussed study designs and hierarchies of evidence, and provided details on conducting randomized controlled trials, a common design for use in systematic reviews. This article describes development of a review protocol and the first two steps in a systematic review: formulating a review question, and searching the literature for relevant research. The emphasis is on systematic reviews of questions related to interventions. The review protocol is developed prior to conducting the review and specifies the plan for the conduct of the review, identifies the roles and responsibilities of the review team and provides structured definitions related to the review question. For intervention questions, the review question should be defined by the PICO components: population, intervention, comparison and outcome(s). The literature search is designed to identify all potentially relevant original research that may address the question. Search terms related to some or all of the PICO components are entered into literature databases, and searches for unpublished literature also are conducted. All steps of the literature search are documented to provide transparent reporting of the process. © 2014 Blackwell Verlag GmbH.

Modeling shoot-tip temperature in the greenhouse environment

International Nuclear Information System (INIS)

Faust, J.E.; Heins, R.D.

1998-01-01

An energy-balance model is described that predicts vinca (Catharanthus roseus L.) shoot-tip temperature using four environmental measurements: solar radiation and dry bulb, wet bulb, and glazing material temperature. The time and magnitude of the differences between shoot-tip and air temperature were determined in greenhouses maintained at air temperatures of 15, 20, 25, 30, or 35 °C. At night, shoot-tip temperature was always below air temperature. Shoot-tip temperature decreased from 0.5 to 5 °C below air temperature as greenhouse glass temperature decreased from 2 to 15 °C below air temperature. During the photoperiod under low vapor-pressure deficit (VPD) and low air temperature, shoot-tip temperature increased ≈4 °C as solar radiation increased from 0 to 600 W·m -2 . Under high VPD and high air temperature, shoot-tip temperature initially decreased 1 to 2 °C at sunrise, then increased later in the morning as solar radiation increased. The model predicted shoot-tip temperatures within ±1 °C of 81% of the observed 1-hour average shoot-tip temperatures. The model was used to simulate shoot-tip temperatures under different VPD, solar radiation, and air temperatures. Since the rate of leaf and flower development are influenced by the temperature of the meristematic tissues, a model of shoot-tip temperature will be a valuable tool to predict plant development in greenhouses and to control the greenhouse environment based on a plant temperature setpoint.

Kelic, Andjelka; Campbell, Philip L

2018-04-01

The National Infrastructure Simulations and Analysis Center (NISAC) conducted a literature review on modeling cyber networks and evaluating cyber risks. The literature review explores where modeling is used in the cyber regime and ways that consequence and risk are evaluated. The relevant literature clusters in three different spaces: network security, cyber-physical, and mission assurance. In all approaches, some form of modeling is utilized at varying levels of detail, while the ability to understand consequence varies, as do interpretations of risk. This document summarizes the different literature viewpoints and explores their applicability to securing enterprise networks.

Wu, Yelena P; Aylward, Brandon S; Roberts, Michael C; Evans, Spencer C

2012-08-01

Literature reviews are an essential step in the research process and are included in all empirical and review articles. Electronic databases are commonly used to gather this literature. However, several factors can affect the extent to which relevant articles are retrieved, influencing future research and conclusions drawn. The current project examined articles obtained by comparable search strategies in two electronic archives using an exemplar search to illustrate factors that authors should consider when designing their own search strategies. Specifically, literature searches were conducted in PsycINFO and PubMed targeting review articles on two exemplar disorders (bipolar disorder and attention deficit/hyperactivity disorder) and issues of classification and/or differential diagnosis. Articles were coded for relevance and characteristics of article content. The two search engines yielded significantly different proportions of relevant articles overall and by disorder. Keywords differed across search engines for the relevant articles identified. Based on these results, it is recommended that when gathering literature for review papers, multiple search engines should be used, and search syntax and strategies be tailored to the unique capabilities of particular engines. For meta-analyses and systematic reviews, authors may consider reporting the extent to which different archives or sources yielded relevant articles for their particular review.

Shoot regeneration of limau purut (citrus hystrix) using shoot tip: assessment of calcium gluconate and silver nitrate in overcoming premature leaf senescence

International Nuclear Information System (INIS)

Eng, W.H.; Aziz, M.A.; Sinniah, U.R.

2014-01-01

This study was carried out to establish an optimum In vitro shoot multiplication system using shoot tip explants derived from 7 week-old seedlings of Citrus hystrix. In the first experiment, shoot tips were cultured on Murashige and Skoog (MS) medium supplemented with 0-13.33 mu M 6-benzylaminopurine (BAP) for 8 weeks. Shoot tips cultured on 2.22 mu M BAP produced the highest mean number of shoots (3.42 shoots) but the shoots had low number of leaves (1.14 leaves) due to the occurrence of premature leaf senescence and callus formation. Meanwhile, the medium devoid of BAP produced the lowest mean number of shoots (1.50 shoots) but highest mean number of leaves (5.41 leaves) indicating that BAP was likely responsible for the premature leaf senescence. In order to overcome the occurrence of premature leaf senescence on medium with BAP, a second experiment was carried out whereby shoot tips were cultured on medium containing 2.22 micro M BAP fortified with 2.00, 4.00 and 6.00 mM calcium gluconate (Ca-glu) and a control treatment with 2.22 mu M BAP. The shoot and leaf numbers were increased with the addition of 4.00 and 6.00 mM Ca-glu. The presence of Ca-glu reduced premature leaf senescence and callus formation to some extent. In the third experiment, the addition of silver nitrate (AgNO/sub 3/) at 10-80 micro M in media with 2.22 micro M BAP and 2.22 micro M BAP + 4 mM Ca-glu could totally overcome premature leaf senescence and callus formation. Media supplemented with 2.22 mirco M BAP + 4 mM Ca-glu + 20 micro M AgNOsub 3/ significantly induced among the highest mean number of shoots and highest mean number of leaves per shoot. (author)

Cycling biomechanics: a literature review.

Wozniak Timmer, C A

1991-01-01

Submitted in partial fulfillment for a Master of Science degree at the University of Pittsburgh, School of Health Related Professions, Pittsburgh, PA 1.5213 This review of current literature on cycling biomechanics emphasizes lower extremity muscle actions and joint excursions, seat height, pedal position, pedaling rate, force application, and pedaling symmetry. Guidelines are discussed for optimal seat height, pedal position, and pedaling rate. Force application in the power and recovery phases of cycling and the relationship of force application to pedaling symmetry are discussed. The need for a biomechanical approach to cycling exists since a great deal of the literature is primarily physiologic in nature. The purpose of this review is to make cyclists and their advisors aware of the biomechanics of cycling and guidelines to follow. This approach is also important because cycling is a very common form of exercise prescribed by physical therapists for clinic or home programs. Biomechanical aspects of cycling should be considered by cyclists at any level of participation and by physical therapists in order for goal-oriented, efficient cycling to occur.

Radiosensitivity of in vitro Cultured Banana Shoot-Tips

International Nuclear Information System (INIS)

Elagamawy, M.R.

2002-01-01

Longitudinally dissected shoot apices of Grand Nain, Williams and Maghrabi banana cultivars were exposed to gamma irradiation with Cobalt 60 source at the doses of 0, 20, 40 and 60 Gy and immediately placed into proliferation medium. A number of micropropagation cycles after irradiation were necessary up to M1 V2 to M1 V4 stage to let mutated sectors developing into non-chimeric shoots. Radiosensitivity was evaluated by the rate of shoot proliferation and by the shoot fresh weight increase. Increasing gamma doses caused reduction in survival rates and average number of shoots. Grand Nain exhibited the highest multiplication- rate (3.1). The lower dose (20 Gy) enhanced shoot multiplication ratio specially in Williams and Maghrabi, which however decreased with increased doses. The doses of 20-40 Gy yielded Ld50, with sensible degree of shoot multiplication, which occurred hardly ever beyond 40 Gy. The dose of 60 Gy resulted 80% lethal shoot growth. Linear decrease in fresh weight was observed in post-irradiation recovery, notably in the Maghrabi. In contradictory vulnerable damage was observed in Williams which showed the highest fresh weight value. Shoot proliferation appeared generally on the surface of the corm. Root formation was observed without additional hormone. The roots were dark colored and was decreased with the increased of dosage

Evaluating trauma nursing education: An integrative literature review.

Ding, Min; Metcalfe, Helene; Gallagher, Olivia; Hamdorf, Jeffrey M

2016-09-01

A review of the current literature evaluating trauma nursing education. A variety of trauma nursing courses exist, to educate nurses working in trauma settings, and to maintain their continuing professional development. Despite an increase in the number of courses delivered, there appears to be a lack of evidence to demonstrate the effectiveness of trauma nursing education and in particular the justification for this resource allocation. Integrative literature review. A search of international literature on trauma nursing education evaluation published in English from 1985 to 2015 was conducted through electronic databases CINAHL Plus, Google Scholar, PubMed, Austhealth, Science Citation Index Expanded (Web of Science), Sciverse Science Direct (Elsevier) & One file (Gale). Only peer reviewed journal articles identifying trauma course and trauma nursing course evaluation have been included in the selection criteria. An integrative review of both quantitative and qualitative literature guided by Whittemore and Knafl's theoretical framework using Bowling's and Pearson's validated appraisal checklists, has been conducted for three months. Only 17 studies met the inclusion criteria, including 14 on trauma course evaluation and 3 on trauma nursing course evaluation. Study findings are presented as two main themes: the historical evolution of trauma nursing education and evaluation of trauma nursing education outcomes. Trauma nursing remains in its infancy and education in this specialty is mainly led by continuing professional development courses. The shortage of evaluation studies on trauma nursing courses reflects the similar status in continuing professional development course evaluation. A trauma nursing course evaluation study will address the gap in this under researched area. Copyright © 2016 Elsevier Ltd. All rights reserved.

The expansion of biomedical literature is creating the need for efficient tools to keep pace with increasing volumes of information. Text mining (TM) approaches are becoming essential to facilitate the automated extraction of useful biomedical information from unstructured text. We reviewed the applications of TM in psychiatry, and explored its advantages and limitations. A systematic review of the literature was carried out using the CINAHL, Medline, EMBASE, PsycINFO and Cochrane databases. In this review, 1103 papers were screened, and 38 were included as applications of TM in psychiatric research. Using TM and content analysis, we identified four major areas of application: (1) Psychopathology (i.e. observational studies focusing on mental illnesses) (2) the Patient perspective (i.e. patients' thoughts and opinions), (3) Medical records (i.e. safety issues, quality of care and description of treatments), and (4) Medical literature (i.e. identification of new scientific information in the literature). The information sources were qualitative studies, Internet postings, medical records and biomedical literature. Our work demonstrates that TM can contribute to complex research tasks in psychiatry. We discuss the benefits, limits, and further applications of this tool in the future. Copyright © 2015 John Wiley & Sons, Ltd. Copyright © 2015 John Wiley & Sons, Ltd.

The age of school shootings: a sociological interpretation on masculinity

Directory of Open Access Journals (Sweden)

Celis, Jorge

2015-01-01

Full Text Available Over the past two decades there has been a growing interest in the study of the horrendous massacres perpetrated by students at school premises. These massacres, known as school shootings, haven been predominantly analyzed by employing psychological approaches. Despite the fact that empirical research clearly reveals that school shooters tend not to present life-long histories of mental illness, these approaches usually put a strong emphasis on the perpetrator’s individual pathologies, ignoring the influence that social values such as masculinity exert on perpetrators’ actions. Consequently, perpetrators are viewed as lone wolf shooters and school shootings as isolated cases. Based on data derived from scholarly works published mainly in peer-review journals and the sociological theory of P. Berger and T. Luckmann, the aim of this essay is to offer a sociological interpretation on school shootings by explaining why school shooters commit violent actions against teachers and classmates as a form of retrieving their masculinity. In this regard, the essay finds that male rather than female students commit school shootings. At the same time, the majority of perpetrators have had parents who were gun collectors. It is no coincide that shooters mostly use family guns to commit the massacres. Additionally, shooters see school as a social entity that has diminished their masculinity, and the way to reaffirm their masculinity is to attack randomly students and teachers in full view of the rest of school members during school hours.

Impact of childhood chronic illnesses on siblings: a literature review.

Science.gov (United States)

O' Brien, Irene; Duffy, Anita; Nicholl, Honor

Childhood illness can have a significant impact on families, particularly on the ill child's siblings. There is a dearth of published literature focusing on the needs of siblings of ill children. This literature review aims to provide an overview of the current healthcare literature in relation to the impact of childhood chronic illness or disability on siblings. A literature review was undertaken by searching the databases CINAHL, PsycINFO, ProQuest and Cochrane Library for relevant articles in English using the search terms: 'siblings', 'chronic illness', 'disability', 'cancer', 'sibling relations', 'sibling adjustment', 'coping', 'family-centred care', 'sibling interventions', 'camps', 'autism', 'Down's syndrome'. Seventeen research studies in total were reviewed. This review focuses on three sibling groups related to children suffering from autism, cancer and Down's syndrome, and are discussed under the following headings: sibling adjustment; family functioning and sibling's coping resources; and intervention programmes. The literature revealed that siblings of children with Down's syndrome were well adjusted to living with their brother or sister. However, there was conflicting information on the adjustment of siblings of children with cancer and autism. An awareness of the harmful effect that living with childhood illness and disability can have on some siblings is essential to enable healthcare professionals to provide supportive interventions to protect siblings' physical and emotional wellbeing.

Work motivation in health care: a scoping literature review.

Perreira, Tyrone A; Innis, Jennifer; Berta, Whitney

2016-12-01

The aim of this scoping literature review was to examine and summarize the factors, context, and processes that influence work motivation of health care workers. A scoping literature review was done to answer the question: What is known from the existing empirical literature about factors, context, and processes that influence work motivation of health care workers? This scoping review used the Arksey and O'Malley framework to describe and summarize findings. Inclusion and exclusion criteria were developed to screen studies. Relevant studies published between January 2005 and May 2016 were identified using five electronic databases. Study abstracts were screened for eligibility by two reviewers. Following this screening process, full-text articles were reviewed to determine the eligibility of the studies. Eligible studies were then evaluated by coding findings with descriptive labels to distinguish elements that appeared pertinent to this review. Coding was used to form groups, and these groups led to the development of themes. Twenty-five studies met the eligibility criteria for this literature review. The themes identified were work performance, organizational justice, pay, status, personal characteristics, work relationships (including bullying), autonomy, organizational identification, training, and meaningfulness of work. Most of the research involved the use of surveys. There is a need for more qualitative research and for the use of case studies to examine work motivation in health care organizations. All of the studies were cross-sectional. Longitudinal research would provide insight into how work motivation changes, and how it can be influenced and shaped. Several implications for practice were identified. There is a need to ensure that health care workers have access to training opportunities, and that autonomy is optimized. To improve work motivation, there is a need to address bullying and hostile behaviours in the workplace. Addressing the factors that

Defining resilience: A preliminary integrative literature review

Science.gov (United States)

Wilt, Bonnie; Long, Suzanna K.; Shoberg, Thomas G.

2016-01-01

The term “resilience” is ubiquitous in technical literature; it appears in numerous forms, such as resilience, resiliency, or resilient, and each use may have a different definition depending on the interpretation of the writer. This creates difficulties in understanding what is meant by ‘resilience’ in any given use case, especially in discussions of interdisciplinary research. To better understand this problem, this research constructs a preliminary integrative literature review to map different definitions, applications and calculation methods of resilience invoked within critical infrastructure applications. The preliminary review uses a State-of-the-Art Matrix (SAM) analysis to characterize differences in definition across disciplines and between regions. Qualifying the various usages of resilience will produce a greater precision in the literature and a deeper insight into types of data required for its evaluation, particularly with respect to critical infrastructure calculations and how such data may be analyzed. Results from this SAM analysis will create a framework of key concepts as part of the most common applications for “resilient critical infrastructure” modeling.

Nuclear Energy Literature Review

International Nuclear Information System (INIS)

Simic, Z.; Wastin, F.

2016-01-01

In the light of five years after a major accident at the Fukushima Daiichi nuclear power plant it is interesting to make nuclear energy related literature review. There is a number of accidents related reports from all major international institutions (like the IAEA and OECD NEA) and research organizations have drawn conclusions and lessons to learn from this terrible accident. These reports are the result of expert and scientific analyses carried out during these five years and they present ideal sources for both understanding what has happened and what can be learned in order to avoid and mitigate effects of such events in the future. From a wider perspective it is also interesting to analyze the impact on research and development (R and D) activities. This literature review is performed with hope to gain some useful insights from the analysis of the volume and topics in all research activities related to the Fukushima accident and nuclear energy (NE) altogether. This kind of review should at least provide an overview of trends and provide base for better planning of future activities. This paper analyzes the published NE related research of over more than 50 years with focus on three major nuclear accidents (TMI, Chernobyl and Fukushima). It has been performed using Scopus tools and database, and mainly focuses on statistics related to the subjects, countries, keywords and type of publishing. It also analyses how responsive is nuclear energy related R and D regarding the volume and subjects, and how is that research spread among most active countries. Nuclear power accidents influence increase and change of research. Both accidents, Chernobyl and Fukushima had maximum share in all nuclear power related papers at similar yearly level (9 percent in 1991 and 12 percent in 2015 respectively). TMI peaked at the 2.5 percent share in 1982. Engineering is the most frequent subjects for TMI and cumulative NE related publishing. Medicine and environmental science subjects

Mass Shootings, Mental Illness, and Gun Control.

Science.gov (United States)

Philpott-Jones, Sean

2018-03-01

In the wake of the Stoneman Douglas School shooting, Republican and Democratic leaders-like the American electorate they represent-remain sharply divided in their responses to gun violence. They are united in their condemnation of these mass shootings, but they disagree about whether stricter or looser gun control laws are the answer. Those on the right side of the political aisle suggest that the issue is one of mental illness rather than gun control. Conversely, those who are more liberal or progressive in their political learnings are quick to condemn attempts to reframe the issue of mass shootings as a mental health problem. Both sides are wrong. Mass shootings are indeed partially a mental health problem, albeit one poorly addressed by our current laws and policies. But the solution to mass shootings also needs to consider strategies that may reduce gun violence in general. © 2018 The Hastings Center.

Post-extubation airway obstruction. Literature review

Directory of Open Access Journals (Sweden)

Álvaro SÁNCHEZ-TABERNERO

2017-03-01

Full Text Available Introduction and objective: airway obstruction after extubation in any surgery is a critical event with low incidence, which may require reintubation or tracheostomy, which often otolaryngologist is required. Objective: To determine the prevalence of BVA and its causes through systematic literature review. Method: Literature review in PubMed, Scopus and Cochrane clinical trials, meta-analysis, reviews and case series and control over airway obstruction after extubation that requires reintubation in adults. Results: 6 studies and one clinical practice guidelines were selected. The most common cause of extubation failure is blocking the airway for various reasons (pharyngeal muscle weakness residual effect -often farmacologycal-, laryngospasm, vocal cord paralysis, edema of upper respiratory tract, cervical postoperative hematoma, foreign bodies or secretions. Most cases of re-intubation occurred within 2 hours after extubation. Conclusions: The most common cause of failure after general anesthesia extubation is blocking the airway generally caused by residual neuromuscular blocking effect. Airway obstruction risk increases in airway and head and neck surgery. Difficult intubation guidlines have improved performance and reduced adverse events and similar strategies must be implemented in extubation. The procedure extubation and reintubation should be documented. Working groups airway must be multidisciplinary and include specialists in otolaryngology.

Literature search strategies for conducting knowledge-building and theory-generating qualitative systematic reviews.

Science.gov (United States)

Finfgeld-Connett, Deborah; Johnson, E Diane

2013-01-01

To report literature search strategies for the purpose of conducting knowledge-building and theory-generating qualitative systematic reviews. Qualitative systematic reviews lie on a continuum from knowledge-building and theory-generating to aggregating and summarizing. Different types of literature searches are needed to optimally support these dissimilar reviews. Articles published between 1989-Autumn 2011. These documents were identified using a hermeneutic approach and multiple literature search strategies. Redundancy is not the sole measure of validity when conducting knowledge-building and theory-generating systematic reviews. When conducting these types of reviews, literature searches should be consistent with the goal of fully explicating concepts and the interrelationships among them. To accomplish this objective, a 'berry picking' approach is recommended along with strategies for overcoming barriers to finding qualitative research reports. To enhance integrity of knowledge-building and theory-generating systematic reviews, reviewers are urged to make literature search processes as transparent as possible, despite their complexity. This includes fully explaining and rationalizing what databases were used and how they were searched. It also means describing how literature tracking was conducted and grey literature was searched. In the end, the decision to cease searching also needs to be fully explained and rationalized. Predetermined linear search strategies are unlikely to generate search results that are adequate for purposes of conducting knowledge-building and theory-generating qualitative systematic reviews. Instead, it is recommended that iterative search strategies take shape as reviews evolve. © 2012 Blackwell Publishing Ltd.

Clinical education and student satisfaction: An integrative literature review

Directory of Open Access Journals (Sweden)

Karen F. Phillips, EdD, MSN, IBCLC, ICCE

2017-04-01

Full Text Available The clinical component of undergraduate clinical education is a critical area in nursing programs. Faculty shortages have made recruitment of clinical faculty and clinical teaching more challenging. As such, alternate models of clinical faculty assignments are being explored to address faculty shortages. This article contains an extensive literature review conducted to survey models of clinical education and student satisfaction with the clinical environment. The purpose of this paper is to examine student satisfaction in the clinical learning environment using articles employing the Clinical Learning Environment Inventory (CLEI along with examining the use of alternate clinical staffing models in differing levels of undergraduate nursing students. A literature search focusing on studies published between 2002 and 2015 was conducted from 5 electronic databases. Thirty-five articles were reviewed and 22 were selected for this literature review. The studies reviewed concluded that students favored a more positive and favorable clinical environment than they perceived as being actually present. A supportive clinical learning environment is of paramount importance in securing positive teaching learning outcomes. Nurse educators can apply the results of this review in order to develop and maintain quality clinical teaching and to promote a positive, student-centric, clinical learning environment.

Mycorrhizal Stimulation of Leaf Gas Exchange in Relation to Root Colonization, Shoot Size, Leaf Phosphorus and Nitrogen: A Quantitative Analysis of the Literature Using Meta-Regression.

Science.gov (United States)

Augé, Robert M; Toler, Heather D; Saxton, Arnold M

2016-01-01

Arbuscular mycorrhizal (AM) symbiosis often stimulates gas exchange rates of the host plant. This may relate to mycorrhizal effects on host nutrition and growth rate, or the influence may occur independently of these. Using meta-regression, we tested the strength of the relationship between AM-induced increases in gas exchange, and AM size and leaf mineral effects across the literature. With only a few exceptions, AM stimulation of carbon exchange rate (CER), stomatal conductance (g s), and transpiration rate (E) has been significantly associated with mycorrhizal stimulation of shoot dry weight, leaf phosphorus, leaf nitrogen:phosphorus ratio, and percent root colonization. The sizeable mycorrhizal stimulation of CER, by 49% over all studies, has been about twice as large as the mycorrhizal stimulation of g s and E (28 and 26%, respectively). CER has been over twice as sensitive as g s and four times as sensitive as E to mycorrhizal colonization rates. The AM-induced stimulation of CER increased by 19% with each AM-induced doubling of shoot size; the AM effect was about half as large for g s and E. The ratio of leaf N to leaf P has been more closely associated with mycorrhizal influence on leaf gas exchange than leaf P alone. The mycorrhizal influence on CER has declined markedly over the 35 years of published investigations.

The Nutritional Facts of Bamboo Shoots and Their Usage as Important Traditional Foods of Northeast India

Science.gov (United States)

Nongdam, P.; Tikendra, Leimapokpam

2014-01-01

Bamboo shoots are considered as one of the useful health foods because of their rich contents of proteins, carbohydrates, vitamins, fibres, and minerals and very low fat. Though bamboo shoots provide lots of health benefits, their consumption is confined mostly to Southeast Asian and East Asian countries. The acceptability of bamboo shoots as popular vegetable crop is very less due to their high pungent smell and bitter acidic taste. The use of bamboo as food in India is mainly restricted to Northeastern part of the country where they form an indispensable part of several traditional speciality dishes. The different ethnic communities take fresh or fermented bamboo shoot as one of most preferred traditional food items. Some of the important bamboo based traditional foods are ushoi, soibum, rep, mesu, eup, ekhung, hirring, and so forth. Bamboo shoots should be properly processed before they are consumed as freshly harvested shoots have high content of toxic cyanogenic glycosides which may pose serious health problems. The prospect of bamboo shoot industry in Northeast India is bright due to its rich genetic resources of bamboos. However, habitat destruction and extensive use of bamboos for food, handicraft, and construction purposes have resulted in severe depletion of natural bamboo resources. This review stresses upon the high nutritive values and health benefits of bamboo shoots and their usage as important traditional foods in Northeast India. The bamboo market potential of the region and use of in vitro plant micropropagation methods as effective means of bamboo conservation are also emphasized in this paper. PMID:27433496

Brown, Angela; Crookes, Patrick; Dewing, Jan

2015-01-01

Clinical leadership and the safety, quality and efficiency of patient/client care are inextricably linked in government reports, major inquiries and the professional literature. This review explores the literature on clinical leadership development within pre-registration nursing programmes. The literature retrieved from a scoping review was evaluated to identify what is already published on the development of clinical leadership within pre-registration nursing programmes. Twenty-seven publications matched the inclusion criteria and were included in this review, 14 journal articles, one thesis and 11 chapters within one book were analysed and three themes were identified: clinical leadership; curriculum content and pedagogy. RESULTS AND MAIN OUTCOMES: This review identified a paucity of literature specifically relating to clinical leadership and pre-registration nursing programmes and what is available is inconclusive and unconvincing. Academics, curriculum development leaders and accreditation bodies have a responsibility to influence how nurses are prepared for the profession as such clinical leadership and the new graduate should be considered an area of greater importance.

Vicarious learning: a review of the literature.

Science.gov (United States)

Roberts, Debbie

2010-01-01

Experiential learning theory stresses the primacy of personal experience and the literature suggests that direct clinical experience is required in order for learning to take place. However, raw or first hand experience may not be the only mechanisms by which students engage in experiential learning. There is a growing body of literature within higher education which suggests that students are able to use another's experience to learn: vicarious learning. This literature review aims to outline vicarious learning within a nursing context. Many of the studies regarding vicarious learning are situated within Higher Education in general, however, within the United States these relate more specifically to nursing students. The literature indicates the increasing global interest in this area. This paper reveals that whilst the literature offers a number of examples illustrating how vicarious learning takes place, opinion on the role of the lecturer is divided and requires further exploration and clarification. The implications for nurse education are discussed.

Full Text Available The global primary literature on Zika virus (ZIKV (n = 233 studies and reports, up to March 1, 2016 has been compiled using a scoping review methodology to systematically identify and characterise the literature underpinning this broad topic using methods that are documented, updateable and reproducible. Our results indicate that more than half the primary literature on ZIKV has been published since 2011. The articles mainly covered three topic categories: epidemiology of ZIKV (surveillance and outbreak investigations 56.6% (132/233, pathogenesis of ZIKV (case symptoms/ outcomes and diagnosis 38.2% (89/233 and ZIKV studies (molecular characterisation and in vitro evaluation of the virus 18.5% (43/233. There has been little reported in the primary literature on ZIKV vectors (12/233, surveillance for ZIKV (13/233, diagnostic tests (12/233 and transmission (10/233. Three papers reported on ZIKV prevention/control strategies, one investigated knowledge and attitudes of health professionals and two vector mapping studies were reported. The majority of studies used observational study designs, 89.7% (209/233, of which 62/233 were case studies or case series, while fewer (24/233 used experimental study designs. Several knowledge gaps were identified by this review with respect to ZIKV epidemiology, the importance of potential non-human primates and other hosts in the transmission cycle, the burden of disease in humans, and complications related to human infection with ZIKV. Historically there has been little research on ZIKV; however, given its current spread through Australasia and the Americas, research resources are now being allocated to close many of the knowledge gaps identified in this scoping review. Future updates of this project will probably demonstrate enhanced evidence and understanding of ZIKV and its impact on public health.

The Global Emergency Medicine Literature Review (GEMLR) conducts an annual search of peer-reviewed and gray literature relevant to global emergency medicine (EM) to identify, review, and disseminate the most important new research in this field to a global audience of academics and clinical practitioners. This year, 17,722 articles written in three languages were identified by our electronic search. These articles were distributed among 20 reviewers for initial screening based on their relevance to the field of global EM. Another two reviewers searched the gray literature, yielding an additional 11 articles. All articles that were deemed appropriate by at least one reviewer and approved by their editor underwent formal scoring of overall quality and importance. Two independent reviewers scored all articles. A total of 848 articles met our inclusion criteria and underwent full review. 63% were categorized as emergency care in resource-limited settings, 23% as disaster and humanitarian response, and 14% as emergency medicine development. 21 articles received scores of 18.5 or higher out of a maximum score 20 and were selected for formal summary and critique. Inter-rater reliability testing between reviewers revealed a Cohen's Kappa of 0.344. In 2017, the total number of articles identified by our search continued to increase. Studies and reviews with a focus on infectious diseases, pediatrics, and trauma represented the majority of top-scoring articles. This article is protected by copyright. All rights reserved.

Uterine leiomyomas are common gynecologic tumor in reproductive-aged women, by age 50, diagnosis shared by urologist, gynecologists and radiologists. The goal of this article is to review the current literature, study the impact of leiomyoma on female lower urinary tract, examine the cause female sexual dysfunction and provide a comprehensive review of current diagnostic, imaging studies, and current treatment of leiomyoma. Clinical leiomyoma studies published from 1956 through 2015 were identified using the PubMed search engines and the key words leiomyoma, fibroid in the current literature. Impact of leiomyoma on the lower urinary tract including female sexual dysfunction was reviewed with terms of "urinary retention", "bladder", "urethra", "dyspareunia", "incontinence", "incomplete bladder emptying", "female sexual dysfunction", and "lower urinary tract" to study the urological and sexual effects of leiomyoma. Literature related to leiomyoma was reviewed from 1965 to present. Women with uterine leiomyomata complained of pelvic pain, menstrual irregularities, infertility, lower urinary tract symptoms and sexual dysfunction. Leiomyoma is a common tumor of the uterus that often clinically impacts on the lower urinary tract and results in urological and sexual symptoms. Leiomyoma can compress and grow into and become adherent to the bladder and surrounding pelvic organs or metastasize into peritoneal organs. Leiomyoma can enlarge and compress the urinary bladder, urethra, and lower end of the ureters. Leiomyoma can cause embarrassing sexual dysfunction in females. Current literature of non-surgical and surgical therapy of leiomyoma is described.

[PSA interest and prostatitis: literature review].

Science.gov (United States)

Bruyère, F; Amine Lakmichi, M

2013-12-01

Prostatitis is easily diagnosed but sometimes associated with PSA measurement. An increased PSA in an asymptomatic patient may be associated with antibiotic use to eliminate the inflammatory part and to confirm prostate biopsy. It seems interesting to confirm or infirm these attitudes with a systematic review of the literature We performed a literature review using the words [prostatitis], [acute prostatitis], [prostate specific antigen], [PSA], in the MEDLINE, Pubmed and AMBASE database searching for articles in French or English published in the past 20 years. PSA is not always increased during an acute prostatitis episode. An increased PSA in an asymptomatic man does not seem to be systematically correlated to prostate inflammation. Analyzing the studies, it seems inaccurate to measure PSA value during a febrile urinary infection episode in men. Systematic use of antibiotic to decrease PSA and not performing prostate biopsy is not relevant and may induce resistance to antibiotic and doesn't induce a reduction risk of having prostate biopsy. PSA is unnecessary in case of febrile urinary tract infection in men. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

Full Text Available Objective. We aimed to systematically review the literature dealing with the epidemiology, classification, clinical course, diagnosis and treatment of thymoma. Material and methods. We reviewed retrospective and prospective randomized trials using Medline and Elibrary databases. Results. The classification system, prognostic factors, paraneoplastic syndromes and their incidence in patients with thyoma were described. The diagnostic value of computed tomography, magnetic resonance imaging and positron emission tomography was evaluated and the methods of morphologic verification were described. The main attention was paid to multimodality treatment of thymoma, including surgery and intraoperative radiotherapy. Conclusion. Thymoma is a rare tumor. The accumulation of long-term follow-up results prompted the changes in clinical management of thymoma. Predisposition to late recurrence even after radical surgery determined multimodality treatment strategies.

Although root-to-shoot communication has been intensively investigated in plants under drought, few studies have examined root-to-shoot communication under chilling. Here we explored whether root-to-shoot communication contributes to the chilling-light tolerance of cucumber shoots and clarified the key signal involves in this communication. After leaf discs chilling-light treatment, the photoinhibitions of Photosystem I (PSI) and Photosystem II (PSII) were similar in leaf discs of two cucumber varieties (JY-3 and JC-4). When the whole plants, including roots, were chilled under light, the photosynthetic performances in JC-4 leaves decreased more seriously than that in JY-3 leaves. However, when the water status of leaves was maintained by warming roots or floating the attached leaves on water, the PSII activity and amount of PSI in the leaves of the two varieties were similar after chilling-light treatment. In addition, the differences of PSII activities and amount of PSI between the two varieties under whole plant chilling-light treatment were independent of ABA pretreatment. Above results indicate that (1) the better water status in leaves under chilling contributes to the higher chilling tolerance of JY-3; (2) the water status, rather than an ABA signal, dominates root-to-shoot communication under chilling and the chilling tolerance of cucumber shoot.

Football injury: a literature review *

Kos, John J.

1979-01-01

A great deal of concern is recently being expressed relative to the playing of tackle football by adolescent Canadians. The purpose of this literature review is to try to summarize the important data from the available world literature. Very few Canadian statistics are available. Most of the data comes from United States experience. Tackle football injury is examined from various perspectives: 1. Equipment 2. Mechanisms of injury 3. Types of injury, with some emphasis on epiphyseal injury 4. Prevention 5. Comparison with other sports Although no “hard and fast” conclusion is drawn, the paper tends to show that: 1. Football is dangerous 2. Football is damaging to many body systems 3. Prevention of injury is difficult under present conditions 4. Alternate games, such as soccer and rugby seem to provide the same benefits with less catastrophic injuries

Service learning and study abroad opportunities have become increasingly popular in nursing education in the past decade. The purpose of this systematic review was to explore existing literature concerning global health experiences in nursing education. Twenty-three empirical articles from 2003 to 2010 were reviewed, building upon existing reviews of international nursing education literature. Research on two-way exchange experiences and models for best practice were found to be lacking. While an array of countries were represented as the visiting or hosting side of the experience, few co-authors from host countries were found, particularly in literature originating from the U.S. The authors recommend that two-way exchange programs be evaluated to identify successful strategies and barriers to success. Ongoing evaluation of exchanges is necessary to ensure continued sustainable partnership and exchange in immersion experiences for nursing students.

Castle, Billie; Wendel, Monica; Kerr, Jelani; Brooms, Derrick; Rollins, Aaron

2018-05-04

Recently, public health has acknowledged racism as a social determinant of health. Much evidence exists on the impact of individual-level racism and discrimination, with little to no examination of racism from the standpoint of systems and structures. The purpose of this systematic literature review is to analyze the extent to which public health currently addresses systemic racism in the published literature. Utilizing the PRISMA guidelines, this review examines three widely used databases to examine published literature covering the topic as well as implications for future research and practice. A total of 85 articles were included in the review analysis after meeting study criteria. Across numerous articles, the terms racism and systemic racism are largely absent. A critical need exists for an examination of the historical impact of systemic racism on the social determinants of health and health of marginalized populations.

Cell walls as a stage for intercellular communication regulating shoot meristem development

Directory of Open Access Journals (Sweden)

Toshiaki eTameshige

2015-05-01

Full Text Available Aboveground organs of plants are ultimately derived/generated from the shoot apical meristem (SAM, which is the proliferative tissue located at the apex of the stem. The SAM contains a population of stem cells that provide new cells for organ/tissue formation. The SAM is composed of distinct cell layers and zones with different properties. Primordia of lateral organs develop at the periphery of the SAM. The shoot apex is a dynamic and complex tissue, and as such intercellular communications among cells, layers and zones play significant roles in the coordination of cell proliferation, growth and differentiation to achieve elaborate morphogenesis. Recent findings have highlighted the importance of a number of singling molecules acting in the cell wall space for the intercellular communication, including classic phytohormones and secretory peptides. Moreover, accumulating evidences reveal that cell wall properties and their modifying enzymes modulate hormone actions. In this review, we overview how behaviors of singling molecules and changes of cell wall properties are integrated for the shoot meristem regulation.

CROSSFLOW FILTRATON: LITERATURE REVIEW

Energy Technology Data Exchange (ETDEWEB)

Duignan, M.

2011-01-01

As part of the Filtration task EM-31, WP-2.3.6, which is a joint effort between Savannah River National Laboratory (SRNL) and the Pacific Northwest National Laboratory (PNNL), tests were planned to evaluate crossflow filtration in order to the improve the use of existing hardware in the waste treatment plants at both the Department of Energy (DOE) Savannah River Site (SRS) and Hanford Site. These tests included experiments to try different operating conditions and additives, such as filter aids, in order to create a more permeable filter cake and improve the permeate flux. To plan the SRNL tests a literature review was performed to provide information on previous experiments performed by DOE laboratories, and by academia. This report compliments PNNL report (Daniel, et al 2010), and is an attempt to try and capture crossflow filtration work performed in the past that provide a basis for future testing. However, not all sources on crossflow filtration could be reviewed due to the shear volume of information available. In this report various references were examined and a representative group was chosen to present the major factors that affect crossflow filtration. The information summarized in this review contains previous operating conditions studied and their influence on the rate of filtration. Besides operating conditions, other attempted improvements include the use of filter aids, a pre-filtration leaching process, the backpulse system, and various types of filter tubes and filter coatings. The results from past research can be used as a starting point for further experimentation that can result in the improvement in the performance of the crossflow filtration. The literature reviewed in this report indicates how complex the crossflow issues are with the results of some studies appearing to conflict results from other studies. This complexity implies that filtration of mobilized stored waste cannot be explained in a simple generic sense; meaning an empirical

2009-04-01

Many acute inpatient psychiatric wards in the UK are permanently locked, although this is contrary to the current Mental Health Act Code of Practice. To conduct a literature review of empirical articles concerning locked doors in acute psychiatric inpatient wards, an extensive literature search was performed in SAGE Journals Online, EBM Reviews, British Nursing Index, CINAHL, EMBASE Psychiatry, International Bibliography of the Social Sciences, Ovid MEDLINE, PsycINFO and Google, using the search terms 'open$', 'close$', '$lock$', 'door', 'ward', 'hospital', 'psychiatr', 'mental health', 'inpatient' and 'asylum'. A total of 11 empirical papers were included in the review. Both staff and patients reported advantages (e.g. preventing illegal substances from entering the ward and preventing patients from absconding and harming themselves or others) and disadvantages (e.g. making patients feel depressed, confined and creating extra work for staff) regarding locked doors. Locked wards were associated with increased patient aggression, poorer satisfaction with treatment and more severe symptoms. The limited literature available showed the urgent need for research to determine the real effects of locked doors in inpatient psychiatry.

An integrative review of the literature on registered nurses' medication competence.

Sulosaari, Virpi; Suhonen, Riitta; Leino-Kilpi, Helena

2011-02-01

The aim of this integrative literature review was to describe registered nurses' medication competence. The objectives of the literature review were to chart the need for future studies and use the results for instrument development. Nurses play a vital role in different phases of a patient's medication process and thus need adequate competence to fulfil their role. Research on nurses' level of medication competence in different competency areas has been published. However, previous studies have lacked a comprehensive or integrated definition or description of medication competence in nursing. Integrative literature review. The integrative literature review followed five stages: (1) problem identification, (2) literature search, (3) data evaluation, (4) data analysis and (5) presentation. Eligible articles were identified via systematic literature search of research and evidence-based--databases. Twenty-one studies met the selection criteria. Eleven competency areas that constitute nurses' medication competence were identified: (1) anatomy and physiology, (2) pharmacology, (3) communication, (4) interdisciplinary collaboration, (5) information seeking, (6) mathematical and medication calculation, (7) medication administration, (8) medication education, (9) assessment and evaluation, (10) documentation and (11) promoting medication safety as part of patient safety. The analysis revealed three major categories which integrate these competency areas: (1) decision making competence, (2) theoretical competence and (3) practical competence. Medication competence requires a solid knowledge base and the ability to apply that knowledge in real-life situations during often complex and dynamic patient medication processes. Decision making competence was found to be an important and integral part of a nurses' theoretical and practical competence. These main competence categories integrated all of the 11 competency areas identified in this review. It is important to determine

The Level of Vision Necessary for Competitive Performance in Rifle Shooting: Setting the Standards for Paralympic Shooting with Vision Impairment.

The aim of this study was to investigate the level of vision impairment (VI) that would reduce performance in shooting; to guide development of entry criteria to visually impaired (VI) shooting. Nineteen international-level shooters without VI took part in the study. Participants shot an air rifle, while standing, toward a regulation target placed at the end of a 10 m shooting range. Cambridge simulation glasses were used to simulate six different levels of VI. Visual acuity (VA) and contrast sensitivity (CS) were assessed along with shooting performance in each of seven conditions of simulated impairment and compared to that with habitual vision. Shooting performance was evaluated by calculating each individual's average score in every level of simulated VI and normalizing this score by expressing it as a percentage of the baseline performance achieved with habitual vision. Receiver Operating Characteristic curves were constructed to evaluate the ability of different VA and CS cut-off criteria to appropriately classify these athletes as achieving 'expected' or 'below expected' shooting results based on their performance with different levels of VA and CS. Shooting performance remained relatively unaffected by mild decreases in VA and CS, but quickly deteriorated with more moderate losses. The ability of visual function measurements to classify shooting performance was good, with 78% of performances appropriately classified using a cut-off of 0.53 logMAR and 74% appropriately classified using a cut-off of 0.83 logCS. The current inclusion criteria for VI shooting (1.0 logMAR) is conservative, maximizing the chance of including only those with an impairment that does impact performance, but potentially excluding some who do have a genuine impairment in the sport. A lower level of impairment would include more athletes who do have a genuine impairment but would potentially include those who do not actually have an impairment that impacts performance in the sport.

(Semi-)systematic approaches to finding, analysing, and synthesising ethics literature on medical topics are still in their infancy. However, our recent systematic review showed that the rate of publication of such (semi-)systematic reviews has increased in the last two decades. This is not only true for reviews of empirical ethics literature, but also for reviews of normative ethics literature. In the latter case, there is currently little in the way of standards and guidance available. Therefore, the methods and reporting strategies of such reviews vary greatly. The purpose of the follow-up study we present was to obtain deeper methodological insight into the ways reviews of normative literature are actually conducted and to analyse the methods used. Our search in the PubMed, PhilPapers, and Google Scholar databases led to the identification of 183 reviews of ethics literature published between 1997 and 2015, of which 84 were identified as reviews of normative and mixed literature. Qualitative content analysis was used to extract and synthesise descriptions of search, selection, quality appraisal, analysis, and synthesis methods. We further assessed quantitatively how often certain methods (e.g. search strategies, data analysis procedures) were used by the reviews. The overall reporting quality varies among the analysed reviews and was generally poor even for major criteria regarding the search and selection of literature. For example, only 24 (29%) used a PRISMA flowchart. Also, only 55 (66%) reviews mentioned the information unit they sought to extract, and 12 (14%) stated an ethical approach as the theoretical basis for the analysis. Interpretable information on the synthesis method was given by 47 (60%); the most common methods applied were qualitative methods commonly used in social science research (83%). Reviews which fail to provide sufficient relevant information to readers have reduced methodological transparency regardless of actual methodological

The Global Emergency Medicine Literature Review (GEMLR) conducts an annual search of peer-reviewed and gray literature relevant to global emergency medicine (EM) to identify, review, and disseminate the most important new research in this field to a global audience of academics and clinical practitioners. This year 13,890 articles written in four languages were identified by our search. These articles were distributed among 20 reviewers for initial screening based on their relevance to the field of global EM. An additional two reviewers searched the gray literature. All articles that were deemed appropriate by at least one reviewer and approved by their editor underwent formal scoring of overall quality and importance. Two independent reviewers scored all articles. A total of 716 articles met our inclusion criteria and underwent full review. Fifty-nine percent were categorized as emergency care in resource-limited settings, 17% as EM development, and 24% as disaster and humanitarian response. Nineteen articles received scores of 18.5 or higher out of a maximum score of 20 and were selected for formal summary and critique. Inter-rater reliability testing between reviewers revealed Cohen's kappa of 0.441. In 2016, the total number of articles identified by our search continued to increase. The proportion of articles in each of the three categories remained stable. Studies and reviews with a focus on infectious diseases, pediatrics, and the use of ultrasound in resource-limited settings represented the majority of articles selected for final review. © 2017 The Authors.

2013-09-01

To provide a current overview of the movement for open access to the peer review literature. Perspective. Literature review of recent advances in the open access movement with a personal viewpoint of the nuances of the movement. The open access movement is complex, with many different constituents. The idealists for the open access movement are seeking open access to the literature but also to the data that constitute the research within the manuscript. The business model of the traditional subscription journal is being scrutinized in relation to the surge in the number of open access journals. Within this environment authors should beware predatory practices. More government and funding agencies are mandating open access to their funded research. This open access movement will continue to be disruptive until a business model ensures continuity of the scientific record. A flood of open access articles that might enrich, but also might pollute or confuse, the medical literature has altered the filtering mechanism provided by the traditional peer review system. At some point there may be a shake-out, with some literature being lost in cyberspace. The open access movement is maturing and must be embraced in some format. The challenge is to establish a sustainable financial business model that will permit the use of digital technology but yet not endanger the decades-old traditional publication model and peer review system. Authors seem to be slower in adopting open access than the idealists in the movement. Copyright © 2013 Elsevier Inc. All rights reserved.

Micropropagation of Asparagus by in vitro shoot culture.

Science.gov (United States)

Stajner, Nataša

2013-01-01

Asparagus officinalis is most extensively studied species within the genus Asparagus, which is well known as garden asparagus. This species is dioecious with unisexual flowers, which means that generative propagation gives roughly equal number of male and female plants. Male plants are high yielders and preferred commercially over female plants. Tissue culture techniques could efficiently promote vegetative propagation of male plants and pave the way for efficient plant breeding.This chapter describes an efficient micropropagation protocol for developing rapid growing in vitro Asparagus shoot cultures. The source of explants, inoculation, and shoot proliferation, followed by shoot propagation, rooting, and acclimatization is described. The optimal medium for Asparagus micropropagation described in this chapter is composed of MS macro- and microelements and a combination of auxins and cytokinins. Plant growth regulators NAA, kinetin, and BA were used in various concentrations. Three different media representing the whole micropropagation protocol of Asparagus are described; medium for shoot initiation, medium for shoot multiplication, and medium for root formation. By in vitro propagation of Asparagus, root initiation is difficult, but can be promoted by adding growth retardant ancymidol which also greatly promotes shoot development and suppresses callus formation.

Borderline personality disorder in men: A literature review and illustrative case vignettes.

Science.gov (United States)

Bayes, Adam; Parker, Gordon

2017-11-01

The aim is to review the salient literature on borderline personality disorder (BPD) in men and link those findings with case vignettes. We provide a literature review and then report case examples of those who met DSM and clinical BPD criteria, and consider the extent to which the small male sub-set corresponded developmentally and phenomenologically with prototypic BPD in women. The review considered phenomenological, epidemiological, biological and developmental BPD factors, finding BPD men evidence elevated substance abuse, and 'externalising' patterns of behavior, antisocial personality traits, violent self-harm and interpersonal aggression, whereas women display more 'internalising' strategies. The five male vignettes enriched the literature review providing support for gender differences reported in our review. The literature and case vignette findings should assist clinicians in recognising that BPD in men may not be as rare as generally viewed, and which may reflect BPD being commonly viewed as weighted to women and being misdiagnosed as an antisocial personality disorder (ASPD) in men.

Light requirement for shoot regeneration in horseradish hairy roots.

Science.gov (United States)

Saitou, T; Kamada, H; Harada, H

1992-08-01

Hairy roots of horseradish (Armoracia rusticana) were induced by inoculation with Agrobacterium rhizogenes harboring Ri plasmid and cultured on phytohormone-free Murashige and Skoog medium after eliminating the bacteria. Hairy roots grew vigorously and sometimes formed yellowish calli under dark conditions. On the other hand, growth of hairy roots stopped after several weeks of culture with light, then shoots were regenerated. Frequency of shoot formation from hairy roots increased as the culture period in light lengthened and the light intensity increased. The shoot regeneration was induced by treatment with white or red light, but not with far-red light. Shoot regeneration by red light was inhibited by following treatment with far-red light. Red and far-red light reversibly affected shoot regeneration. Excised roots of nontransformed plants grew quite slowly on phytohormone-free Murashige and Skoog medium and occasionally formed shoots under white light conditions.

Evidence for Busines Intelligence in Health Care: A Literature Review.

Science.gov (United States)

Loewen, Liz; Roudsari, Abdul

2017-01-01

This paper outlines a systematic literature review undertaken to establish current evidence regarding the impact of Business Intelligence (BI) on health system decision making and organizational performance. The review also examined BI implementation factors contributing to these constructs. Following the systematic review, inductive content analysis was used to categorize themes within the eight articles identified. This study demonstrated there is little evidence based literature focused on BI impact on organizational decision making and performance within health care. There was evidence found that BI does improve decision making. Implementation success was found to be dependent on several factors, many of which relate to broader organizational culture and readiness.

A procedure for the mass propagation of multiple shoots of Stevia rebaudiana is described. Isolated shoot primordia were used as the inoculum to obtain clusters of shoot primordia. Such clusters were grown in a 500 liter bioreactor to obtain shoots. A total of 64.6 Kg of shoots were propagated from 460 g of the inoculated shoot primordia. These shoots were easily acclimatized in soil.

Problematizing the concept ‘epistemological access’: A review of literature

Directory of Open Access Journals (Sweden)

Lucinda du Plooy

2014-07-01

Full Text Available This paper provides a review of literature which aims at problematizing the concept ‘epistemological access”, a fairly under-researched topic in South African education. Morrow’s distinction between formal access (institutional access and epistemological access (access to the goods distributed by the institution is used as a conceptual framework. We argue that the meaning of the concept ‘epistemological access’ as Morrow intended was borne out of a particular political need that arose in higher education; the need to democratize access to higher education. The dearth of literature on the concept “epistemological access” and its meaning for access to basic education, especially foundation phase schooling, therefore warranted this literature review.

Full Text Available Purpose: This paper reports on some of the findings of a literature review commissioned to explore integrated care for older people. Methods: The process of revising included finding and selecting literature from multidisciplinary sources, and encompassed both published papers and ‘grey’ literature, i.e. material which had not been reviewed for publication. Results: The study found that thinking has moved on from a focus on the problems of accessing services to exploring ways in which they may function in an integrated way. Conclusions: The study shows how thinking on integrated care for older people has developed, and knowledge of micro, mezzo and macro strategies is now more available.

Emotionally intelligent nurse leadership: a literature review study.

Science.gov (United States)

Akerjordet, Kristin; Severinsson, Elisabeth

2008-07-01

To establish a synthesis of the literature on the theoretical and empirical basis of emotional intelligence and it's linkage to nurse leadership, focusing on subjective well-being and professional development. Emotional intelligence has been acknowledged in the literature as supporting nurse leadership that fosters a healthy work environment, creating inspiring relationships based on mutual trust. Nurse leaders who exhibit characteristics of emotional intelligence enhance organizational, staff and patient outcomes. A literature search was undertaken using international data bases covering the period January 1997 to December 2007. Eighteen articles were included in this integrative review and were thoroughly reviewed by both authors. Emotional intelligence was associated with positive empowerment processes as well as positive organizational outcomes. Emotionally intelligent nurse leadership characterized by self-awareness and supervisory skills highlights positive empowerment processes, creating a favourable work climate characterized by resilience, innovation and change. Emotional intelligence cannot be considered a general panacea, but it may offer new ways of thinking and being for nurse leaders, as it takes the intelligence of feelings more seriously by continually reflecting, evaluating and improving leadership and supervisory skills.

This article aims to examine gender stereotypes in relation to men in nursing, discuss gender discrimination cases in nursing, and explore methods used for promoting equal educational opportunities during nursing studies. The literature review was based on related databases, such as CINAHL, Science Direct, MEDLINE, and EBSCO. Legal case studies are included in order to provide a more practical example of those barriers existing for men pursuing nursing, as well as statistical data concerning gender discrimination and male attrition to nursing schools in relation to those barriers. These strengthen the validity of the manuscript. Literature review showed that gender discrimination is still prevalent within nursing profession. Nursing faculty should prepare male nursing students to interact effectively with female clients as well. Role modeling the therapeutic relationship with clients is one strategy that may help male students. In general, the faculty should provide equal learning opportunities to nursing students.

Exposure to lead in South African shooting ranges

International Nuclear Information System (INIS)

Mathee, Angela; Jager, Pieter de; Naidoo, Shan; Naicker, Nisha

2017-01-01

Introduction: Lead exposure in shooting ranges has been under scrutiny for decades, but no information in this regard is available in respect of African settings, and in South Africa specifically. The aim of this study was to determine the blood lead levels in the users of randomly selected private shooting ranges in South Africa's Gauteng province. Methods: An analytical cross sectional study was conducted, with participants recruited from four randomly selected shooting ranges and three archery ranges as a comparator group. Results: A total of 118 (87 shooters and 31 archers) were included in the analysis. Shooters had significantly higher blood lead levels (BLL) compared to archers with 36/85 (42.4%) of shooters versus 2/34 (5.9%) of archers found to have a BLL ≥10 μg/dl (p<0.001). Conclusion: Shooting ranges may constitute an import site of elevated exposure to lead. Improved ventilation, low levels of awareness of lead hazards, poor housekeeping, and inadequate personal hygiene facilities and practices at South African shooting ranges need urgent attention. - Highlights: • This is the first study, to our knowledge, of lead exposure in shooting ranges in an African setting. • This study indicates highly elevated lead exposure amongst the users of certain private shooting ranges in South Africa. • Lead exposure may be a serious, yet under-studied, source of adult lead exposure in South Africa, and possibly elsewhere on the African continent.

Full Text Available The objective of this work was to evaluate shoot growth of the grapevine varieties Merlot and Cabernet Sauvignon, during 2006/2007, and Cabernet Sauvignon, during 2008/2009, in São Joaquim, SC, Brazil. The experiment was carried out in a commercial vineyard trained on a vertical trellis system. The shoots of the central part of the plants were selected, and the lengths from the base to the apex of 20 shoots per cultivar were evaluated. In 2006/2007, monitoring began at pruning, on 9/15/2006, and ended on 2/6/2007, totalizing 144 days of evaluation. During the 2008/2009 cycle, phenology and shoot growth for 'Cabernet Sauvignon' were assessed from grape development (1/13/2009 (pea-sized grapes until shoot vegetative growth had ceased. Budburst occurred in the second half of September, and shoot-growth cessation occurred during ripening. Higher growth rates (about 4 cm per day were observed in pre- and post-flowering, followed by reduction due to the competition for photosynthates for the formation of flowers and bunches. Temperature and photoperiod induce grapevine shoots to cease growth in the highland regions of Santa Catarina State, Brazil.

The Level of Vision Necessary for Competitive Performance in Rifle Shooting: Setting the Standards for Paralympic Shooting With Vision Impairment

Directory of Open Access Journals (Sweden)

Peter M Allen

2016-11-01

Full Text Available The aim of this study was to investigate the level of vision impairment that would reduce performance in shooting; to guide development of entry criteria to visually impaired (VI shooting. Nineteen international-level shooters without vision impairment took part in the study. Participants shot an air rifle, while standing, towards a regulation target placed at the end of a 10m shooting range. Cambridge simulation glasses were used to simulate six different levels of vision impairment. Visual acuity (VA and contrast sensitivity (CS were assessed along with shooting performance in each of seven conditions of simulated impairment and compared to that with habitual vision. Shooting performance was evaluated by calculating each individual’s average score in every level of simulated vision impairment and normalising this score by expressing it as a percentage of the baseline performance achieved with habitual vision. Receiver Operating Characteristic (ROC curves were constructed to evaluate the ability of different VA and CS cut-off criteria to appropriately classify these athletes as achieving ‘expected’ or ‘below expected’ shooting results based on their performance with different levels of VA and CS. Shooting performance remained relatively unaffected by mild decreases in VA and CS, but quickly deteriorated with more moderate losses. The ability of visual function measurements to classify shooting performance was good, with 78% of performances appropriately classified using a cut-off of 0.53 logMAR and 74% appropriately classified using a cut-off of 0.83 logCS. The current inclusion criteria for VI shooting (1.0 logMAR is conservative, maximising the chance of including only those with an impairment that does impact performance, but potentially excluding some who do have a genuine impairment in the sport. A lower level of impairment would include more athletes who do have a genuine impairment but would potentially include those who do not

Simpson, Michelle R

2009-07-01

Engagement at work has emerged as a potentially important employee performance and organizational management topic, however, the definition and measurement of engagement at work, and more specifically, nurse engagement, is poorly understood. The objective of this paper is to examine the current state of knowledge about engagement at work through a review of the literature. This review highlights the four lines of engagement research and focuses on the determinants and consequences of engagement at work. Methodological issues, as identified in the current research, and recommendations for future nurse-based engagement research are provided. A systematic review of the business, organizational psychology, and health sciences and health administration literature about engagement at work (1990-2007) was performed. The electronic databases for Health Sciences and Health Administration (CINAHL, MEDLINE), Business (ABI INFORM), and Psychology (PsycINFO) were systematically searched. Due to the limited amount of research that has examined engagement among the nursing workforce, published research that included varying employee types were included in this review. The selection criteria for this review include those studies that were: (1) written in English and (2) examined engagement at work in employee populations of any type within any work setting. The literature review identified four distinct lines of research that has focused on engagement within the employee work role. Of the 32 engagement-based articles referenced in this paper, a sample of 20 studies report on the examination of antecedents and/or consequences of engagement at work among varying employee types and work settings. Key findings suggest organizational factors versus individual contributors significantly impact engagement at work. A common implication in this body of research was that of the performance-based impact. The study of nurses' work engagement and its relationship to nurses' organizational

2018-05-09

Patents and patent portfolios are gaining attention in the last decades, from the called 'pro-patent era' to the recent billionaire transactions involving patent portfolios. The field is growing in importance, both theoretically and practically and despite having substantial literature on new product development portfolio management, we have not found an article relating this theory to patent portfolios. Areas covered: The paper develops a systematic literature review on patent portfolio management to organize the evolution and tendencies of patent portfolio management, highlighting distinctive features of patent portfolio management. Interview with IP manager of three life sciences companies, including a leading multinational group provided relevant information about patent portfolio management. Expert opinion: Based on the systematic literature review on portfolio management, more specifically, on new product development portfolio theory, and interview the paper proposes the paper proposes a reference model to manage patent portfolios. The model comprises four stages aligned with the three goals of the NPD portfolio management: 1 - Linking strategy of the Company's NPD Portfolio to Patent Portfolio; 2 - Balancing the portfolio in buckets; 3 - Patent Valuation (maximizing valuation); 4 - Regularly reviewing the patent portfolio.

Cancer remains the second leading cause of mortality in the United States. Special events such as health fairs, screening days or cultural festivals are employed often for community education about cancer screening. A previous systematic review of the published literature was conducted in 2012-2013. The purpose of this study was to conduct a grey literature component of special events that promote breast, cervical and colorectal cancer screening in the U.S. We conducted a grey literature search of dissertations/theses and conference abstracts. The theses/dissertations were restricted to those: 1) written in English, 2) published from January 1990 to December 2011, 3) examined at least one of the predefined categories of special events, 4) involved cancer screening for breast, cervical, and/or colorectal cancer, 5) included outcome data, and 6) conducted in the United States. A review of U.S. public health and cancer conference abstracts, that were readily available and had focused on at least of 3 cancer types and included outcome data, was conducted. Data were abstracted on the purpose, location, primary audience(s), activities conducted, screening provided onsite or referrals, and evaluation results. The grey literature review found 6 special events. The types of events found added to the numbers found in the systematic review, especially receptions or parties and cultural festivals/events. All focused on increasing breast and cervical cancer screening except one that focused on breast cancer only. The reach of these events was targeted at mostly minorities or underserved communities. Common evidence-based strategies were group education, small media, and reducing structural barriers. Group education involved presentations from physicians, lay-health advisors, or cancer survivors, while reducing structural barriers included activities such as providing screening appointment sign-ups at the event or providing transportation for event participants.

Peharec, P; Posilović, H; Balen, B; Krsnik-Rasol, M

2010-07-01

Artificial conditions of tissue culture affect growth and physiology of crassulacean acid metabolism plants which often results in formation of hyperhydric shoots. In in vitro conditions Mammillaria gracilis Pfeiff. (Cactaceae) growth switches from organized to unorganized way, producing a habituated organogenic callus which simultaneously regenerates morphologically normal as well as altered hyperhydric shoots. In this study, influence of tissue culture conditions on morphology of cactus spines of normal and hyperhydric shoots was investigated. Spines of pot-grown Mammillaria plants and of in vitro regenerated shoots were examined with stereo microscope and scanning electron microscope. The pot-grown plants had 16-17 spines per areole. In vitro grown normal shoots, even though they kept typical shoot morphology, had lower number of spines (11-12) and altered spine morphology. This difference was even more pronounced in spine number (six to seven) and morphology of the hyperhydric shoots. Scanning electron microscopy analysis revealed remarkable differences in micromorphology of spine surface between pot-grown and in vitro grown shoots. Spines of in vitro grown normal shoots showed numerous long trichomes, which were more elongated on spines of the hyperhydric shoots; the corresponding structures on spine surface of pot-grown plants were noticed only as small protrusions. Scanning electron microscopy morphometric studies showed that the spines of pot-grown plants were significantly longer compared to the spines of shoots grown in tissue culture. Moreover, transverse section shape varies from elliptical in pot-grown plants to circular in normal and hyperhydric shoots grown in vitro. Cluster and correspondence analyses performed on the scanning electron microscope obtained results suggest great variability among spines of pot-grown plants. Spines of in vitro grown normal and hyperhydric shoots showed low level of morphological variation among themselves despite the

Makopa Kenda, Israel; Agoub, Mohamed; Ahami, A O T

2014-01-01

Any human activity generates noise. It is considered as a risk factor for people's health. The present review of literature has assessed the impact of noise on mental health; it is summarized into four points: objective, methods, results and conclusion. The main objective of this study is to expose the actual knowledge state of noise effects on mental health after overview and critical analysis of literature to identify the acquired and shortcomings, to reflect on research direction in terms of noise pollution in the future. The literature review was conducted based on: research of keys words in articles published, research of the number of quotations of articles in Journal Citation Reports (JCR), published in web of science, research of impact factor of journals. One hundred articles were selected, after analyzing contents, items were classified into: fundamental studies (25%), experimental studies (50%), and epidemiological studies (25%). The fundamental studies have verified the hypothesis according to which noise generates stress. Researchers have dosed hormones of stress in plasma, urine and saliva in individuals exposed to noise of different decibels. The results found were unanimous: The rates of stress hormones found, were significantly high in three liquids. This means that noise causes stress. For experimental studies, researchers have experienced the role of noise on memory, attention and performance. Human subjects were exposed to different decibels to assess level of disruption to their memory, attention, and performance. The results revealed that noise disturbs memory, distracts attention and decreases performance. Experimental studies are the most abundant and constitute 50% of the current literature review.The epidemiological studies have evaluated the intellectual performance of students in schools located in noisy environments and residents in areas surrounding airports, railways and highways. RESULTS have revealed that students in schools located

Social marketing and breastfeeding: a literature review.

Schmidt, Manuela

2013-02-08

Through the review of relevant literature this study illuminates the concepts of social marketing and breastfeeding. It specifically discusses the positioning of the link between social marketing and breastfeeding within different fields of study and develops a theoretical framework that tries to bridge the gap between those disciplines. Various electronic databases were used and through systematic selection 11 scientific articles were identified that this literature review is based on. The review indicates that the relationship between social marketing and breastfeeding is complex. There are indications that this relationship is being investigated within three distinct fields of research: psychology/education, public health and marketing. Depending on the research field the emphasis is put on either breastfeeding or social marketing as well as on the other concepts that were discovered to be of importance within this relationship. Namely, group and individual demography as well as behaviour were revealed to be important elements of the link between social marketing and breastfeeding. Based on the results this study concludes that a more multidimensional view on the relationship between the concepts under study is needed since the focus of previous studies is very one-sided and limited to just one element when all elements should be integrated equally.

Effects of patient death on nursing staff: a literature review.

Science.gov (United States)

Wilson, Janet; Kirshbaum, Marilyn

There were 509090 deaths recorded in England and Wales for 2008 (Office for National Statistics, 2010); of these, over 56% (260000) occurred in NHS hospitals. The death of a patient is an event that most, if not all, nursing staff will encounter during their work. This experience can elicit physical, cognitive, behavioural, spiritual and emotional responses (Parkes, 1998). The aim of this literature review is to explore how the death of patients in a hospital setting impact on nursing staff. A review of the literature was undertaken using the online databases CINAHL, Medline and PsychInfo. The search was limited to articles in the English language and those from peer-reviewed journals. Themes arising from the literature review included: the theoretical context; the emotional impact; the culture of the healthcare setting; staff's previous life experiences; and support available for healthcare staff. The death of patients does have an impact on nurses. This can affect them both in their work environment and outside of work. Education around grief theory and support from others are helpful for staff in developing strategies for coping with patient deaths.

Tubercular prosthetic joint infection (TB-PJI) is an uncommon complication. Lack of evidence of systemic tuberculosis and clinical suspicion could bring a delay in the time of the diagnosis. The aims of this study are to underline the importance of awareness and suspicion of mycobacterial infection in the differential diagnosis in PJI and to evaluate the appropriateness of different therapeutic options. Case report and literature review. We report two cases of TB-PJI after total knee arthroplasty in Caucasian patients without prior history of tubercular disease or exposure. In both cases, the diagnosis was obtained years after the onset of symptoms. Despite that, both patients improved during antitubercular treatment (a four-drug regimen consisting of rifampicin, isoniazid, ethambutol, and pyrazinamide for 2 months, followed by rifampicin and isoniazid). Moreover, after an 18-month course of treatment, there was no need for surgical therapy. The result of the literature review allows us to identify 64 cases of TB-PJI. Many differences in both medical and surgical management have been found, among those reviewed cases. Considering our experience and the literature review, we recommend considering a conservative approach (debridement and adequate antituberculous chemotherapy) as a suitable and safe option.

Grady, K.L.

1982-08-01

Callus tissue derived from Nicotiana tabacum L. stem pith parenchyma cells was grown either on medium which maintains the callus in an undifferentiated state, or on medium which induces the formation of shoots. Two complementary types of studies were performed with the goal of establishing metabolic markers for the initiation of shoot formation: one designed to characterize the flow of radioactive sucrose into various metabolic pools, and one which allowed measurement of intermediary metabolite concentrations. In the former, callus tissue was incubated in (U-/sup 14/C)sucrose for periods up to one hour, and patterns of metabolite labelling in tissue grown on shoot-forming and non-shoot-forming media were compared. In the latter studies, tissue was grown for an entire subculture period on non-shoot-forming medium labelled with (U-/sup 14/C)sucrose, then subcultured to labelled non-shoot-forming or shoot-forming media, and sampled at intervals during the first week of growth. 189 references.

Individual Alpha Peak Frequency in Ice Hockey Shooting Performance

Directory of Open Access Journals (Sweden)

Sommer Christie

2017-05-01

Full Text Available There are several important inter- and intra-individual variations in individual alpha peak frequency (IAPF in the cognitive domain. The rationale for the present study was to extend the research on IAPF in the cognitive domain to IAPF in the sport domain. Specifically, the purpose of the present study was twofold: (a to explore whether baseline IAPF is related to performance in an ice hockey shooting task and (b to explore whether a shooting task has an effect on IAPF variability. The present investigation is one of the first studies to examine links between IAPF and sport performance. Study results did not show significant changes in IAPF when comparing baseline IAPF and pre- to post-task IAPF across three performance levels. The findings support previous literature in the cognitive domain suggesting that IAPF is a stable neurophysiological marker. Future research should consider the following methodological suggestions: (a measuring IAPF during sport performance instead of at a resting state, (b changing the pre-performance resting baseline instructions to take into account sport-specific mental preparation, (c exploring an expert-novice paradigm to accentuate performance ability differences between groups (d comparing tasks with different levels of complexity, and (e analyzing the possible correlation between IAPF and performance on different days.

Regeneration and health: a structured, rapid literature review.

Science.gov (United States)

McCartney, G; Hearty, W; Taulbut, M; Mitchell, R; Dryden, R; Collins, C

2017-07-01

To identify and synthesise what is known about the impacts of regeneration on health, health inequalities and their socio-economic determinants. Rapid, structured literature review. A rapid, structured approach was undertaken to identifying relevant studies involving a search of peer-reviewed literature databases, an Internet search to identify relevant grey literature, and a review of articles citing two key systematic reviews. The identified citations were screened, critically appraised according to the research design and narratively synthesised. Of the 1382 identified citations, 46 were screened as relevant to the review and included in the synthesis. Fifteen citations were reviews but most of the evidence identified or included within the reviews was of medium or low quality due to a lack of longitudinal follow-up, low response rates or attrition. The evidence base on the impacts of regeneration is generally not of high quality and is prone to bias. However, it is theorised as being an important means of addressing the socio-economic determinants of health. Housing refurbishment (generally, and for specific improvements) seems likely to lead to small improvements in health, whereas rehousing and mixed-tenure approaches have less clear impacts on health and carry risks of disruption to social networks and higher rents. Changes in the social composition of communities (gentrification) is a common outcome of regeneration and some 'partnership' approaches to regeneration have been shown to have caused difficulties within communities. The evidence base for regeneration activities is limited but they have substantial potential to contribute to improving population health. Better quality evidence is available for there being positive health impacts from housing-led regeneration programmes involving refurbishment and specific housing improvements. There is also some evidence of the potential harms of regeneration activities, including social stratification

Cell fate regulation in the shoot meristem.

Science.gov (United States)

Laux, T; Mayer, K F

1998-04-01

The shoot meristem is a proliferative centre containing pluripotent stem cells that are the ultimate source of all cells and organs continuously added to the growing shoot. The progeny of the stem cells have two developmental options, either to renew the stem cell population or to leave the meristem and to differentiate, possibly according to signals from more mature tissue. The destiny of each cell depends on its position within the dynamic shoot meristem. Genetic data suggest a simple model in which graded positional information is provided by antagonistic gene functions and is interpreted by genes which regulate cell fate.

A literature review of safety culture.

Energy Technology Data Exchange (ETDEWEB)

Cole, Kerstan Suzanne; Stevens-Adams, Susan Marie; Wenner, Caren A.

2013-03-01

Workplace safety has been historically neglected by organizations in order to enhance profitability. Over the past 30 years, safety concerns and attention to safety have increased due to a series of disastrous events occurring across many different industries (e.g., Chernobyl, Upper Big-Branch Mine, Davis-Besse etc.). Many organizations have focused on promoting a healthy safety culture as a way to understand past incidents, and to prevent future disasters. There is an extensive academic literature devoted to safety culture, and the Department of Energy has also published a significant number of documents related to safety culture. The purpose of the current endeavor was to conduct a review of the safety culture literature in order to understand definitions, methodologies, models, and successful interventions for improving safety culture. After reviewing the literature, we observed four emerging themes. First, it was apparent that although safety culture is a valuable construct, it has some inherent weaknesses. For example, there is no common definition of safety culture and no standard way for assessing the construct. Second, it is apparent that researchers know how to measure particular components of safety culture, with specific focus on individual and organizational factors. Such existing methodologies can be leveraged for future assessments. Third, based on the published literature, the relationship between safety culture and performance is tenuous at best. There are few empirical studies that examine the relationship between safety culture and safety performance metrics. Further, most of these studies do not include a description of the implementation of interventions to improve safety culture, or do not measure the effect of these interventions on safety culture or performance. Fourth, safety culture is best viewed as a dynamic, multi-faceted overall system composed of individual, engineered and organizational models. By addressing all three components of

Radiographing roots and shoots

1985-01-01

The effect of seed orientation on germination time and on shoot and root growth patterns is studied. Neutron radiography is used to observe the development of 4 types of plants, maize, greenpea, soya bean and padi. These plants were grown in varying orientations; sand sizes, sand thicknesses, and level of water content. Radiography of the seeds and plants were obtained for time exposure ranging from 3-12 hours and at reactor thermal power level, ranging from 500-750 kilowatts. Results obtained showed that seeds planted in varying orientations need different length of time for shoot emergence. Neutron radiography is now developed to other areas of non-industrial applications in Malaysia. (A.J.)

Several types of vasculitis have been observed and reported in temporal association with the administration of various vaccines. A systematic review of current evidence is lacking. This systematic literature review aimed to assess available evidence and current reporting practice of vasculitides as adverse events following immunization (AEFI). We reviewed the literature from 1st January 1994 to 30th June 2014. This review comprises randomized controlled trials, observational studies, case series, case reports, reviews and comments regardless of vaccine and target population. The initial search resulted in the identification of 6656 articles. Of these, 157 articles were assessed for eligibility and 75 studies were considered for analysis, including 6 retrospective/observational studies, 2 randomized controlled trials, 7 reviews, 11 case series, 46 case reports and 3 comments. Most of the larger, higher quality studies found no causal association between vaccination and subsequent development of vasculitis, including several studies on Kawasaki disease and Henoch-Schönlein purpura (IgA vasculitis). Smaller case series reported a few cases of vasculitis following BCG and vaccines against influenza and hepatitis. Only 24% of the articles reported using a case definition of vasculitis. Existing literature does not allow establishing a causative link between vaccination and vasculitides. Further investigations were strengthened by the use of standardized case definitions and methods for data collection, analysis and presentation to improve data comparability and interpretation of vasculitis cases following immunization.

Objective: To analyze the clinical, imaging and pathological features of adamantinoma of long bone to aid preoperative diagnosis. Methods: A case of adamantinoma of long bone was reported and the related literature was reviewed. Results: Literature review showed that long bone ameloblastoma was more common in young adults older than 20 years of age (86.3%) and occurred mainly in the tibial shaft (90%). The clinical, imaging and pathological features in our patient were consistent with those reported in the literature. Among 39 cases in the Chinese literature, radiographic findings included uni-or multi-cystic bone destruction with well-defined borders (87.2%), bone expansion (61.8%), partial loss of cortical bone (26.5%), bone sclerosis (38.2%), and no periosteal new bone reaction (100%). Pathology showed epithelial and fibrous differentiation. Conclusion: Adamantinoma of long bone should be considered in patients older than 20 years of age with tibial lesions that have imaging characteristics of benign bone tumors or some malignant features.

Advanced manufacturing technology (AMT) provides advantages to manufacturing managers in terms of flexibility, quality, reduced delivery times, and global competitiveness. Although a large number of publications had presented the importance of this technology, only a few had delved into related literature review. Considering the importance of this technology and the recent contributions by various authors, the present paper conducts a more comprehensive review. Literature was reviewed in a way that will help researchers, academicians, and practitioners to take a closer look at the implementation, evaluation, and justification of the AMT. The authors reviewed various papers, proposed a different classification scheme, and identified certain gaps that will provide hints for further research in AMT management.

Full Text Available Several past studies have found that media reports of suicides and homicides appear to subsequently increase the incidence of similar events in the community, apparently due to the coverage planting the seeds of ideation in at-risk individuals to commit similar acts.Here we explore whether or not contagion is evident in more high-profile incidents, such as school shootings and mass killings (incidents with four or more people killed. We fit a contagion model to recent data sets related to such incidents in the US, with terms that take into account the fact that a school shooting or mass murder may temporarily increase the probability of a similar event in the immediate future, by assuming an exponential decay in contagiousness after an event.We find significant evidence that mass killings involving firearms are incented by similar events in the immediate past. On average, this temporary increase in probability lasts 13 days, and each incident incites at least 0.30 new incidents (p = 0.0015. We also find significant evidence of contagion in school shootings, for which an incident is contagious for an average of 13 days, and incites an average of at least 0.22 new incidents (p = 0.0001. All p-values are assessed based on a likelihood ratio test comparing the likelihood of a contagion model to that of a null model with no contagion. On average, mass killings involving firearms occur approximately every two weeks in the US, while school shootings occur on average monthly. We find that state prevalence of firearm ownership is significantly associated with the state incidence of mass killings with firearms, school shootings, and mass shootings.

Antiarrhythmic drugs are commonly prescribed cardiac drugs. Due to their receptor mimicry with several of the gastrointestinal tract receptors, they can frequently lead to gastrointestinal side effects. These side effects are the most common reasons for discontinuation of these drugs by the patients. Knowledge of these side effects is important for clinicians that manage antiarrhythmic drugs. This review focuses on the gastrointestinal side effects of these drugs and provides a detailed up-to-date literature review of the side effects of these drugs. The review provides case reports reported in the literature as well as possible mechanisms that lead to gastrointestinal side effects.

Full Text Available This report describes the effect of triacontanol on shoot multiplication and production of antioxidant compounds (carnosic acid, carnosol and rosmarinic acid in S. officinalis cultures grown on MS basal medium (agar solidified medium supplemented with 0.1 mg l-1 IAA, 0.45 mg l-1 BAP. It was found that shoot proliferation significantly increased when triacontanol at concentrations of 5, 10 or 20 µg l-1 was added to the medium. HPLC analysis of acetone and methanolic extracts of sage shoots showed that the production of diterpenoids, carnosic acid/carnosol ratio, as well as, contents of rosmarinic acid were also affected by the treatment with triacontanol. The highest stimulation effect of triacontanol was observed on the production of carnosol, where the treatment with 20 µg l l-1 increased the content of this diterpenoid 4.5-fold compared to that in the control (sage shoots growing on MS basal medium, only.

Australian Mass Shootings: An Analysis of Incidents and Offenders.

Science.gov (United States)

McPhedran, Samara

2017-06-01

Mass shooting events are relatively underresearched, and most study comes from the United States. Despite significant international interest, little is known about other countries' experiences of these events. The current study examines Australian mass shooting incidents and offenders, with emphasis on mental illness, life strains, and offenders' life histories. Australia had 14 mass shootings between 1964 and 2014. Most offenders experienced acute life stressors and/or chronic strains leading up to the event; however, diagnosed mental illness was less commonly documented. These observations provide new information about mass shooting incidents and offenders, and can help to inform international policy development.

Self-weighing in weight management: a systematic literature review.

2015-02-01

Regular self-weighing, which in this article is defined as weighing oneself regularly over a period of time (e.g., daily, weekly), is recommended as a weight loss strategy. However, the published literature lacks a review of the recent evidence provided by prospective, longitudinal studies. Moreover, no paper has reviewed the psychological effects of self-weighing. Therefore, the objective is to review the literature related to longitudinal associations between self-weighing and weight change as well as the psychological outcomes. Electronic literature searches in PubMed, Ovid PsycINFO, and Ebscohost CINAHL were conducted. Keywords included overweight, obesity, self-weighing, etc. Inclusion criteria included trials that were published in the past 25 years in English; participants were adults seeking weight loss treatment; results were based on longitudinal data. The results (N=17 studies) revealed that regular self-weighing was associated with more weight loss and not with adverse psychological outcomes (e.g., depression, anxiety). Findings demonstrated that the effect sizes of association between self-weighing and weight change varied across studies and also that the reported frequency of self-weighing varied across studies. The findings from prospective, longitudinal studies provide evidence that regular self-weighing has been associated with weight loss and not with negative psychological outcomes. © 2014 The Obesity Society.

Data on the factors associated with school shootings in the USA are limited. The public conversation has often suggested several factors that may be linked to these events, however with little empirical support. Aiming to fill this gap, we describe the characteristics of school shooting incidents in the USA between 2013 and 2015 and explore whether four factors that represent domains of firearm policy, educational policy and epidemiological risk factors for intentional firearm injuries-background check (BC) policies, per capita mental health expenditures (MHE), K-12 education expenditure (KEE) and urbanicity-were associated with school shootings during this period. We searched LexisNexis, a newspaper and broadcast media databases for school shooting incidents from 1 January 2013 to 31 December 2015. Presence of BC laws was extracted from legal information in LexisNexis. State-level covariates of per capita MHE (2013), KEE (2013) and urbanicity (2010) rates were obtained from publicly available data sources. We used negative binomial regression models accounting for clustering by state to explore unadjusted associations between the BC laws, state-level covariates and school shootings to report IRR and 95% CI. We documented 154 school shootings (35, 55 and 64 each year). In unadjusted models, BC for firearm purchase (IRR=0.55, 95% CI 0.39 to 0.76), ammunition purchase (IRR=0.11, 95% CI 0.05 to 0.27), log per capita MHE (IRR=0.58, 95% CI 0.37 to 0.90), log per-capita KEE (IRR=0.09, 9% CI 0.02 to 0.29) and urbanicity (IRR=0.97, 95% CI 0.96 to 0.99) were associated with school shooting. School shootings are less likely in states with BC laws, higher MHE and KEE, and with greater per cent urban population. Published by the BMJ Publishing Group Limited.

Burget, Mirjam; Bardone, Emanuele; Pedaste, Margus

2017-02-01

The aim of this study is to provide a discussion on the definitions and conceptual dimensions of Responsible Research and Innovation based on findings from the literature. In the study, the outcomes of a literature review of 235 RRI-related articles were presented. The articles were selected from the EBSCO and Google Scholar databases regarding the definitions and dimensions of RRI. The results of the study indicated that while administrative definitions were widely quoted in the reviewed literature, they were not substantially further elaborated. Academic definitions were mostly derived from the institutional definitions; however, more empirical studies should be conducted in order to give a broader empirical basis to the development of the concept. In the current study, four distinct conceptual dimensions of RRI that appeared in the reviewed literature were brought out: inclusion, anticipation, responsiveness and reflexivity. Two emerging conceptual dimensions were also added: sustainability and care.

Toode, Kristi; Routasalo, Pirkko; Suominen, Tarja

2011-02-01

The aim of this review is to describe nurses' work motivation from the perspective of staff nurses. This information would be useful for the development of motivation strategies and further research into nurses' work motivation. A thorough review of the research literature. The literature search was performed using four databases: CINAHL, PubMed, PsychINFO, and SocINDEX. Only studies that met the following criteria were selected for review: (1) were published between 1990 and 2009, (2) were written in English, (3) dealt with work motivation, (4) concerned working staff nurses, (5) involved empirical research, (6) clearly and explicitly provided the research results about the factors affecting nurses' work motivation. Altogether 24 studies met these criteria and were included in this review. Inductive content analysis was carried out to analyse and categorise the data. Nursing research has neither clear understanding nor consensus about the concept of work motivation; nor has a universal definition been adopted. Despite limited empirical evidence it may be concluded that staff nurses appear to be motivated. Five categories of factors affecting their work motivation were identified: (1) work-place characteristics, (2) working conditions, (3) personal characteristics, (4) individual priorities, and (5) internal psychological states. Further research is needed to gain a more comprehensive insight into nurses' work motivation and the factors affecting it. This can be achieved by defining the concept of work motivation as precisely as possible, working out a pertinent research methodology, and subsequently developing and testing a theoretical model of nurses' work motivation.

T Patial

2017-01-01

Full Text Available Purpose of Review: Gossypibomas remain a dreaded and unwanted complication of surgical practice. Despite significant interest and numerous guidelines, the number of reported cases remains sparse due to various factors, including potential legal implications. Herein, we review related data from India to ascertain if the problem is better or worse than that reported in world literature. Materials and Methods: A literature search was performed on PubMed and Google Scholar, to collect and analyze all case reports and case reviews regarding the condition in India. Results: On analysis of the results, there were 100 publications reporting a total of 126 events. The average patient age was 38.65 years. Average time to discovery was 1225.62 days. Forty-nine percent of reported cases were discovered within the 1 st year. The most common clinical features were pain (73.8%, palpable mass (47.6%, vomiting (35%, abdominal distention (26%, and fever (12.6%. Spontaneous expulsion of the gossypiboma was noted in five cases (3.96%. Transmural migration was seen in 36 cases (28.57%. Conclusions: Despite advancements in surgical approaches and preventive measures, gossypibomas continue to be a cause of significant morbidity. A safe working culture, open communication, teamwork, and an accurate sponge count remain our best defence against this often unpredictable complication of surgery.

Laparoscopic Whipple procedure: review of the literature.

Science.gov (United States)

Gagner, Michel; Palermo, Mariano

2009-01-01

Laparoscopic pancreatic surgery represents one of the most advanced applications for laparoscopic surgery currently in use. In the past, minimally invasive techniques were only used for diagnostic laparoscopy, staging of pancreatic cancer, and palliative procedures for unresectable pancreatic cancer. With new advances in technology and instrumentation, some sophisticated procedures are currently available, such as the Whipple procedure, one of the most sophisticated applications of minimally invasive surgery. A review of the literature shows that 146 laparoscopic Whipple procedures have been published worldwide since 1994. The authors analyzed blood loss, mean operating time, hospital stay, conversion rate, mean age, mortality rate, lymph nodes in the pathologic findings, follow up, and complications. Mean age was 59.1 years; mean operating time was 439 min. The average blood loss for the reviewed literature was 143 mL; median hospital stay was 18 days; conversion rate was 46%; number of lymph nodes in the pathologic findings was 19; and mortalities related to the procedure was low, 2 patients (1.3%) and the complication rate was 16% (23/46 patients). Complications included 2 hemorrhages, 4 bowel obstructions, 1 stress ulcer, 1 delay of gastric emptying, 4 pneumonias, and 11 leaks. This review demonstrates that the laparoscopic Whipple procedure is not only feasible but also safe, with low mortality and acceptable rates of complications.

Mass Shootings: The Role of the Media in Promoting Generalized Imitation.

Science.gov (United States)

Meindl, James N; Ivy, Jonathan W

2017-03-01

Mass shootings are a particular problem in the United States, with one mass shooting occurring approximately every 12.5 days. Recently a "contagion" effect has been suggested wherein the occurrence of one mass shooting increases the likelihood of another mass shooting occurring in the near future. Although contagion is a convenient metaphor used to describe the temporal spread of a behavior, it does not explain how the behavior spreads. Generalized imitation is proposed as a better model to explain how one person's behavior can influence another person to engage in similar behavior. Here we provide an overview of generalized imitation and discuss how the way in which the media report a mass shooting can increase the likelihood of another shooting event. Also, we propose media reporting guidelines to minimize imitation and further decrease the likelihood of a mass shooting.

Full Text Available Recent fraud scandals involving highly known corporations like Enron, WorldCom, and Xerox have eroded public confidence in financial reporting. At the same time, the auditing profession has suffered a big hit. In this scenario, Continuous Auditing (CA seems to have emerged as a response to recover the credibility of the auditing profession as well as meeting Sarbanes-Oxley (SOX requirements. This study, that adopts an exploratory approach, analyzes the existing literature on this topic. First, we address the concepts, models and implications of CA. After, throughout a search on the journals indexed at the CAPES's Basis, a literature review is conducted. A total of 57 articles were selected. We analyze authorship, affiliation, publications, year and type of research of papers that have addressed CA. Findings evidence that most articles addressing CA are non-empirical and adopt a conceptual approach. Also, there is an increasing tendency of continuous auditing studies. Rutgers University seems to be the World's leading research center on CA. This study aims to contribute to the Accounting Science by evidencing possibilities for research and publication in CA.

Kantar, Lina

2014-05-01

The purpose of this literature review was to explore the use of distinct assumptions of constructivism when studying the impact of problem-based learning (PBL) on learners in undergraduate nursing programs. Content analysis research technique. The literature review included information retrieved from sources selected via electronic databases, such as EBSCOhost, ProQuest, Sage Publications, SLACK Incorporation, Springhouse Corporation, and Digital Dissertations. The literature review was conducted utilizing key terms and phrases associated with problem-based learning in undergraduate nursing education. Out of the 100 reviewed abstracts, only 15 studies met the inclusion criteria for the review. Four constructivist assumptions based the review process allowing for analysis and evaluation of the findings, followed by identification of issues and recommendations for the discipline and its research practice in the field of PBL. This literature review provided evidence that the nursing discipline is employing PBL in its programs, yet with limited data supporting conceptions of the constructivist perspective underlying this pedagogical approach. Three major issues were assessed and formed the basis for subsequent recommendations: (a) limited use of a theoretical framework and absence of constructivism in most of the studies, (b) incompatibility between research measures and research outcomes, and (c) brief exposure to PBL during which the change was measured. Educators have made the right choice in employing PBL as a pedagogical practice, yet the need to base implementation on constructivism is mandatory if the aim is a better preparation of graduates for practice. Undeniably there is limited convincing evidence regarding integration of constructivism in nursing education. Research that assesses the impact of PBL on learners' problem-solving and communication skills, self-direction, and motivation is paramount. Copyright © 2014 Elsevier Ltd. All rights reserved.

Light Requirement for Shoot Regeneration in Horseradish Hairy Roots 1

Science.gov (United States)

Saitou, Tsutomu; Kamada, Hiroshi; Harada, Hiroshi

1992-01-01

Hairy roots of horseradish (Armoracia rusticana) were induced by inoculation with Agrobacterium rhizogenes harboring Ri plasmid and cultured on phytohormone-free Murashige and Skoog medium after eliminating the bacteria. Hairy roots grew vigorously and sometimes formed yellowish calli under dark conditions. On the other hand, growth of hairy roots stopped after several weeks of culture with light, then shoots were regenerated. Frequency of shoot formation from hairy roots increased as the culture period in light lengthened and the light intensity increased. The shoot regeneration was induced by treatment with white or red light, but not with far-red light. Shoot regeneration by red light was inhibited by following treatment with far-red light. Red and far-red light reversibly affected shoot regeneration. Excised roots of nontransformed plants grew quite slowly on phytohormone-free Murashige and Skoog medium and occasionally formed shoots under white light conditions. PMID:16669041

Infections caused by Nocardia farcinica are potentially lethal because of the organism's tendency to disseminate and resist antibiotics. Central nervous system involvement has been documented in 30% of infections caused N. farcinica. Case report and review of the literature. A case of primary brain abscess caused by N. farcinica, identified by 16SrRNA sequencing, is presented, and 39 cases reported previously in the literature are reviewed. Our patient underwent a neuronavigation-guided right frontal craniotomy and was treated with trimethoprim/sulfamethoxazole and amoxicillin-clavulanic acid for 12 mo. He showed marginal improvement in his prior left hemiparesis at the last review 14 months later. Cases of N. farcinica infections are being reported increasingly because of recent changes in taxonomy and diagnostic methodology. This change in epidemiology has implications for therapy because of the organism's pathogenicity and natural resistance to multiple antimicrobial agents, including third-generation cephalosporins. Any delay in starting appropriate antibiotic therapy can have adverse consequences.

Toothbrush Contamination: A Review of the Literature

Directory of Open Access Journals (Sweden)

Michelle R. Frazelle

2012-01-01

Full Text Available Toothbrushes are commonly used in hospital settings and may harbor potentially harmful microorganisms. A peer-reviewed literature review was conducted to evaluate the cumulative state of knowledge related to toothbrush contamination and its possible role in disease transmission. A systematic review was conducted on adult human subjects through three distinct searches. The review resulted in seven experimental and three descriptive studies which identified multiple concepts related to toothbrush contamination to include contamination, methods for decontamination, storage, design, and environmental factors. The selected studies found that toothbrushes of healthy and oral diseased adults become contaminated with pathogenic bacteria from the dental plaque, design, environment, or a combination of factors. There are no studies that specifically examine toothbrush contamination and the role of environmental factors, toothbrush contamination, and vulnerable populations in the hospital setting (e.g., critically ill adults and toothbrush use in nursing clinical practice.

Kivisto, Aaron J; Ray, Bradley; Phalen, Peter L

2017-07-01

To examine whether stricter firearm legislation is associated with rates of fatal police shootings. We used a cross-sectional, state-level design to evaluate the effect of state-level firearm legislation on rates of fatal police shootings from January 1, 2015, through October 31, 2016. We measured state-level variation in firearm laws with legislative scorecards from the Brady Center, and for fatal police shootings we used The Counted, an online database maintained by The Guardian. State-level firearm legislation was significantly associated with lower rates of fatal police shootings (incidence rate ratio = 0.961; 95% confidence interval = 0.939, 0.984). When we controlled for sociodemographic factors, states in the top quartile of legislative strength had a 51% lower incidence rate than did states in the lowest quartile. Laws aimed at strengthening background checks, promoting safe storage, and reducing gun trafficking were associated with fewer fatal police shootings. Legislative restrictions on firearms are associated with reductions in fatal police shootings. Public Health Implications. Although further research is necessary to determine causality and potential mechanisms, firearm legislation is a potential policy solution for reducing fatal police shootings in the United States.

We conducted this study to analyze the correlation between 137 Cs concentration of new shoots harvested in the first crop of tea in 2012, and new shoots harvested in the shuto-bancha in 2011 and old leaves harvested at the same time respectively. In the first crop of tea in 2012, the 137 Cs concentration of new shoots was related to that of old leaves, and the correlation of the coefficient was 0.663(p 137 Cs concentration(new shoots/old leaves) was related to the days until harvest of the first crop of tea in 2012, and the correlation coefficient was -0.771(p 137 Cs concentration was derived from the dilution effect due to growth and development of tea plants. Regression analysis was performed to forecast the 137 Cs concentration of the new shoots in the first crop of tea. The 137 Cs concentration of new shoots in the harvested first crop of tea(Y) was related to the 137 Cs concentration of old leaves harvested the previous winter(X). The correlation of the coefficient was 0.783(p 137 Cs concentration of new shoots of the first crop of tea in 2012 decreased about 1/6 to 1/25 compared with that of new shoots of the first crop of tea in 2011.

Flipped classroom: a review of recent literature

Directory of Open Access Journals (Sweden)

Huseyin Uzunboylu

2015-07-01

Full Text Available The use of learning technologies, especially multimedia provide varied facilities for students’ learning that are not possible with other media. Pedagogical literature has proved that individuals have different learning styles. Flipped classroom is a pedagogical approach which means that activities that have traditionally taken place inside the classroom take place outside the classroom and vice versa. Flipped classroom environment ensures that students become more active participants compared with the traditional classroom. The purpose of this paper is to fulfil the needs regarding the review of recent literature on the use of flipped classroom approach in education. The contribution of flipped classroom to education is discussed in relation to the change of students' and instructors' role. Subsequently, flipped classroom applications in various disciplines of education are illustrated. The recommendations made in the literature for design specifications that integrate flipped classrooms with technology are discussed. The paper concludes that a careful consideration of the warnings and recommendations made in the literature can help to produce effective flipped classroom environments and also this paper attempts to inform those who are thinking of using new technologies and approaches to deliver courses.

Dextromethorphan, chlorphenamine and serotonin toxicity: case report and systematic literature review

Science.gov (United States)

Monte, Andrew A; Chuang, Ryan; Bodmer, Michael

2010-01-01

The aim of this review was to describe a patient with serotonin toxicity after an overdose of dextromethorphan and chlorphenamine and to perform a systematic literature review exploring whether dextromethorphan and chlorphenamine may be equally contributory in the development of serotonin toxicity in overdose. A Medline literature review was undertaken to identify cases of serotonin toxicity due to dextromethorphan and/or chlorphenamine. Case reports were included if they included information on the ingested dose or plasma concentrations of dextromethorphan and/or chlorphenamine, information about co-ingestions and detailed clinical information to evaluate for serotonin toxicity. Cases were reviewed by two toxicologists and serotonin toxicity, defined by the Hunter criteria, was diagnosed when appropriate. The literature was then reviewed to evaluate whether chlorphenamine may be a serotonergic agent. One hundred and fifty-five articles of dextromethorphan or chlorphenamine poisoning were identified. There were 23 case reports of dextromethorphan, of which 18 were excluded for lack of serotonin toxicity. No cases were identified in which serotonin toxicity could be solely attributed to chlorphenamine. This left six cases of dextrometorphane and/or chlorphenamine overdose, including our own, in which serotonin toxicity could be diagnosed based on the presented clinical information. In three of the six eligible cases dextromethorphan and chlorphenamine were the only overdosed drugs. There is substantial evidence from the literature that chlorphenamine is a similarly potent serotonin re-uptake inhibitor when compared with dextrometorphan. Chlorphenamine is a serotonergic medication and combinations of chlorphenamine and dextromethorphan may be dangerous in overdose due to an increased risk of serotonin toxicity. PMID:21175434

Immunomodulatory dietary polysaccharides: a systematic review of the literature

Directory of Open Access Journals (Sweden)

Nelson Erika D

2010-11-01

Full Text Available Abstract Background A large body of literature suggests that certain polysaccharides affect immune system function. Much of this literature, however, consists of in vitro studies or studies in which polysaccharides were injected. Their immunologic effects following oral administration is less clear. The purpose of this systematic review was to consolidate and evaluate the available data regarding the specific immunologic effects of dietary polysaccharides. Methods Studies were identified by conducting PubMed and Google Scholar electronic searches and through reviews of polysaccharide article bibliographies. Only articles published in English were included in this review. Two researchers reviewed data on study design, control, sample size, results, and nature of outcome measures. Subsequent searches were conducted to gather information about polysaccharide safety, structure and composition, and disposition. Results We found 62 publications reporting statistically significant effects of orally ingested glucans, pectins, heteroglycans, glucomannans, fucoidans, galactomannans, arabinogalactans and mixed polysaccharide products in rodents. Fifteen controlled human studies reported that oral glucans, arabinogalactans, heteroglycans, and fucoidans exerted significant effects. Although some studies investigated anti-inflammatory effects, most studies investigated the ability of oral polysaccharides to stimulate the immune system. These studies, as well as safety and toxicity studies, suggest that these polysaccharide products appear to be largely well-tolerated. Conclusions Taken as a whole, the oral polysaccharide literature is highly heterogenous and is not sufficient to support broad product structure/function generalizations. Numerous dietary polysaccharides, particularly glucans, appear to elicit diverse immunomodulatory effects in numerous animal tissues, including the blood, GI tract and spleen.

Ownership Structure and Publicness of Firms: A Literature Review

Directory of Open Access Journals (Sweden)

Wisnu Untoro

2017-11-01

Full Text Available There has been an extensive body of literature studying the link between ownership structure and firm performance. Some of them focus on the performance difference across ownership types (i.e. state vs foreign vs private domestic. On the other hand, some studies stress ownership structure on the fraction of ownership based on agency theory (i.e. majority versus minority and its derivatives (e.g. ultimate ownership, cross listing. However, an important element has not been explored while discussing ownership structure of firms which is the concept of publicness of firms. Publicness is important to explain to which extent an organization is related with governmental institutions. In fact, there are many engagements of firms with governmental bodies (e.g. deposit and lending from and to public organization. In this present paper, I provide a comprehensive literature review on the intersection between publicness level of firms and ownership structure. Going deeper, I also provide a literature review on the measurement of publicness and postulate a model to link between these two and firm performance as a venue for future studies.

Midwives and nutrition education during pregnancy: a literature review.

Science.gov (United States)

Arrish, Jamila; Yeatman, Heather; Williamson, Moira

2014-03-01

This review explored the extent to which the role of midwives in nutrition education during pregnancy has been reported in the literature and areas requiring further research were identified. A review of the literature was undertaken. Articles included in the review were published in English, in scholarly journals, and provided information about the knowledge, education, and attitudes of midwives towards nutrition during pregnancy. Few studies were identified. The included studies were exploratory and descriptive. Studies had reported that midwives lacked a basic knowledge of nutrition requirements during pregnancy. This might be attributed to inadequate nutrition education provided in both undergraduate and postgraduate midwifery programmes. The nutrition education components of midwifery courses were not identified within the studies reviewed. Limited international or Australian research is available that reports on the role of midwives in nutrition education during pregnancy and the nutrition content of midwifery curricula. This represents an important omission in midwives capacity to support the health of pregnant women and their babies. More research is required to explore the educational needs of midwives to enhance nutritional care for pregnant women. Copyright © 2013 Australian College of Midwives. Published by Elsevier Ltd.

Quality and Operations Management in Food Supply Chains: A Literature Review

Directory of Open Access Journals (Sweden)

Yong He

2018-01-01

Full Text Available We present a literature review on quality and operations management problems in food supply chains. In food industry, the quality of the food products declines over time and should be addressed in the supply chain operations management. Managing food supply chains with operations management methods not only generates economic benefit, but also contributes to environmental and social benefits. The literature on this topic has been burgeoning in the past few years. Since 2005, more than 100 articles have been published on this topic in major operations research and management science journals. In this literature review, we concentrate on the quantitative models in this research field and classify the related articles into four categories, that is, storage problems, distribution problems, marketing problems, and food traceability and safety problems. We hope that this review serves as a reference for interested researchers and a starting point for those who wish to explore it further.

The Role of Google Scholar in Evidence Reviews and Its Applicability to Grey Literature Searching.

Science.gov (United States)

Haddaway, Neal Robert; Collins, Alexandra Mary; Coughlin, Deborah; Kirk, Stuart

2015-01-01

Google Scholar (GS), a commonly used web-based academic search engine, catalogues between 2 and 100 million records of both academic and grey literature (articles not formally published by commercial academic publishers). Google Scholar collates results from across the internet and is free to use. As a result it has received considerable attention as a method for searching for literature, particularly in searches for grey literature, as required by systematic reviews. The reliance on GS as a standalone resource has been greatly debated, however, and its efficacy in grey literature searching has not yet been investigated. Using systematic review case studies from environmental science, we investigated the utility of GS in systematic reviews and in searches for grey literature. Our findings show that GS results contain moderate amounts of grey literature, with the majority found on average at page 80. We also found that, when searched for specifically, the majority of literature identified using Web of Science was also found using GS. However, our findings showed moderate/poor overlap in results when similar search strings were used in Web of Science and GS (10-67%), and that GS missed some important literature in five of six case studies. Furthermore, a general GS search failed to find any grey literature from a case study that involved manual searching of organisations' websites. If used in systematic reviews for grey literature, we recommend that searches of article titles focus on the first 200 to 300 results. We conclude that whilst Google Scholar can find much grey literature and specific, known studies, it should not be used alone for systematic review searches. Rather, it forms a powerful addition to other traditional search methods. In addition, we advocate the use of tools to transparently document and catalogue GS search results to maintain high levels of transparency and the ability to be updated, critical to systematic reviews.

Evidence for benefits from treating cervical ectopy: literature review

Directory of Open Access Journals (Sweden)

Luís Carlos Machado Junior

Full Text Available CONTEXT AND PURPOSE: Uterine cervical ectopy (cervical erosion is today considered to be a physiological condition, but there still seems to be a strong tendency towards treating it. The purpose of this study was to review the medical literature for evidence regarding benefits from treating cervical ectopy. METHODS: The following databases were reviewed: Medical Literature Analysis and Retrieval System Online (Medline, Excerpta Medica Database (Embase, Literatura Latino-Americana e do Caribe em Ciências da Saúde (Lilacs and Cochrane Library databases. In addition, six medical textbooks were consulted. RESULTS: The review showed that: 1 there is probably an association between ectopy and higher risk of Chlamydia trachomatis, human papillomavirus and human immunodeficiency virus infection; 4 there is probably an association between ectopy and cervical intraepithelial neoplasia; 5 there is an association between ectopy and mucous discharge and nocturia; and 6 there is no evidence of an association between ectopy and cervical cancer, or of protection against cervical cancer associated with ectopy treatment. CONCLUSIONS: 1 No data were found in the medical literature to support routine treatment for ectopy; 2 Treatment could be recommended for symptom relief, but more symptoms are attributed to ectopy than could be demonstrated in a controlled study; 3 Further studies to test the hypothesis of protection against cervical cancer associated with treatment are necessary.

Literature review: Phytoaccumulation of chromium, uranium, and plutonium in plant systems

Phytoremediation is an integrated multidisciplinary approach to the cleanup of contaminated soils, which combines the disciplines of plant physiology, soil chemistry, and soil microbiology. Metal hyperaccumulator plants are attracting increasing attention because of their potential application in decontamination of metal-polluted soils. Traditional engineering technologies may be too expensive for the remediation of most sites. Removal of metals from these soils using accumulator plants is the goal of phytoremediation. The emphasis of this review has been placed on chromium (Cr), plutonium (Pu), and uranium (U). With the exception of Cr, these metals and their decay products exhibit two problems, specifically, radiation dose hazards and their chemical toxicity. The radiation hazard introduces the need for special precautions in reclamation beyond that associated with non-radioactive metals. The uptake of beneficial metals by plants occurs predominantly by way of channels, pores, and transporters in the root plasma membrane. Plants characteristically exhibit a remarkable capacity to absorb what they need and exclude what they don`t need. But most vascular plants absorb toxic and heavy metals through their roots to some extent, though to varying degrees, from negligible to substantial. Sometimes absorption occurs because of the chemical similarity between beneficial and toxic metals. Some plants utilize exclusion mechanisms, where there is a reduced uptake by the roots or a restricted transport of the metal from root to shoot. At the other extreme, hyperaccumulator plants absorb and concentrate metals in both roots and shoots. Some plant species endemic to metalliferous soils accumulate metals in percent concentrations in the leaf dry matter.

Nonhuman primate dermatology: a literature review

Science.gov (United States)

Bernstein, Joseph A.; Didier, Peter J.

2015-01-01

In general, veterinary dermatologists do not have extensive clinical experience of nonhuman primate (NHP) dermatoses. The bulk of the published literature does not provide an organized evidence-based approach to the NHP dermatologic case. The veterinary dermatologist is left to extract information from both human and veterinary dermatology, an approach that can be problematic as it forces the clinician to make diagnostic and therapeutic decisions based on two very disparate bodies of literature. A more cohesive approach to NHP dermatology – without relying on assumptions that NHP pathology most commonly behaves similarly to other veterinary and human disease – is required. This review of the dermatology of NHP species includes discussions of primary dermatoses, as well as diseases where dermatologic signs represent a significant secondary component, provides a first step towards encouraging the veterinary community to study and report the dermatologic diseases of nonhuman primates.

Blake, Marianne; Mitchell, Gary

2016-01-20

Aim To present a narrative review of the empirical literature on the use of horticultural therapy in dementia care. Method A comprehensive literature search, conducted in December 2014, resulted in the selection of 15 primary research articles for review. Of these, three used qualitative methods, five used quantitative methods and seven used mixed methodology. The articles were critically appraised, and the narrative synthesis used a thematic approach whereby prominent themes from the articles were grouped to form representative themes. Findings Three main themes emerged from the narrative synthesis: the emotional health of people living with dementia, their perceived self-identity and their levels of engagement. Conclusion Horticultural therapy can be beneficial. At a macro-level, it is an inexpensive therapy that does not require specialist training to deliver. At a micro-level, it enhances the wellbeing of people living with dementia. Recommendations are made to promote access to appropriate horticultural therapy for people living with dementia, and for further research in this area.

WOMEN’S EMPOWERMENT AND FAMILY PLANNING: A REVIEW OF THE LITERATURE

Summary This paper reviews the literature examining the relationship between women’s empowerment and contraceptive use, unmet need for contraception and related family planning topics in developing countries. Searches were conducted using PubMed, Popline and Web of Science search engines in May 2013 to examine literature published between January 1990 and December 2012. Among the 46 articles included in the review, the majority were conducted in South Asia (n = 24). Household decision-making (n = 21) and mobility (n = 17) were the most commonly examined domains of women’s empowerment. Findings show that the relationship between empowerment and family planning is complex, with mixed positive and null associations. Consistently positive associations between empowerment and family planning outcomes were found for most family planning outcomes but those investigations represented fewer than two-fifths of the analyses. Current use of contraception was the most commonly studied family planning outcome, examined in more than half the analyses, but reviewed articles showed inconsistent findings. This review provides the first critical synthesis of the literature and assesses existing evidence between women’s empowerment and family planning use. PMID:28069078

Social science literature on the environment: review and prospects for energy studies. A preliminary literature survey

Energy Technology Data Exchange (ETDEWEB)

Sommers, P.

1975-01-01

Much of the social science literature on environment is of recent origin and represents the response of the social science research community to a complex societal problem in which technology is a major factor. Energy represents another such problem to which the social science research community is now turning its attention. Because energy problems and environment problems have some similarities and because energy-conversion processes have large effects on the environment, a review of the social science literature on environment was undertaken. The purposes of this review are as follows: (1) to study the possible utility in energy research of some of the concepts developed in social science research on the environment; (2) to study the possible utility in energy research of some of the methodologies utilized in social science research on the environment; and (3) to study the extent to which the results of social science research on the environment have contributed to the development of policy. The first two items above receive major attention in this preliminary literature survey. 50 references.

Research quality and psychological theory in publications on school shooters with multiple victims - A systematic review of the literature

Directory of Open Access Journals (Sweden)

Pål Grøndahl

2016-12-01

Full Text Available School shooting homicide events generate considerable attention. A substantial number of research reports have tried to explain the phenomenon. However, the outcome of these studies has produced a conflicting picture of the issue. Our systematic review explored the quality of research in publications on school shooters. Research quality was assessed concerning description of design, method and interpretation of results according to PRISMA and CRD criteria. We investigated evidence of the impact of psychological theories on how research was designed and interpreted. A total of 10 papers met the criteria for inclusion in the review. With a few exceptions, the research quality was low. Only three studies contained a separate methods section. Two out of ten studies reported from an interview with a school shooter. Secondary sources such as school, hospital and/or psychological evaluations were used in four studies, while the rest had only applied tertiary data sources. There was a void of psychological theoretical analysis to inform the creation of relevant research designs. No study discussed psychological theories to inform inference from empirical data to conclusion. Higher quality of research and enhanced focus on theoretical understanding of psychological factors in school shooting are called upon.

In previous decades, manufacturers faced a lot of challenges because of globalization and high competition in markets. These problems arise from shortening product life cycle, rapid variation in demand of products, and also rapid changes in manufcaturing technologies. Nowadays most manufacturing companies expend considerable attention for improving flexibility and responsiveness in order to overcome these kinds of problems and also meet customer's needs. By considering the trend toward the shorter product life cycle, the manufacturing environment is towards manufacturing a wide variety of parts in small batches [1]. One of the major techniques which are applied for improving manufacturing competitiveness is Cellular Manufacturing System (CMS). CMS is type of manufacturing system which tries to combine flexibility of job shop and also productivity of flow shop. In addition, Dynamic cellular manufacturing system which considers different time periods for the manufacturing system becomes an important topic and attracts a lot of attention to itself. Therefore, this paper made attempt to have a brief review on this issue and focused on all published paper on this subject. Although, this topic gains a lot of attention to itself during these years, none of previous researchers focused on reviewing the literature of that which can be helpful and useful for other researchers who intend to do the research on this topic. Therefore, this paper is the first study which has focused and reviewed the literature of dynamic cellular manufacturing system.

Wright, Stella; McSherry, Wilfred

2013-05-01

This systematic review provides an overview of the literature published on Releasing Time to Care: The Productive Ward between 2005 and June 2011. Releasing Time to Care: The Productive Ward programme was developed by the NHS Institute for Innovation and Improvement and launched in England in 2007. The programme comprises thirteen modules that aim to increase time for direct patient care, improve the patient and staff experience and make changes to the ward environment to improve efficiency. A systematic literature review. The terms 'Releasing Time to Care' and 'Productive Ward' were applied to key healthcare databases; CINAHL, Medline, Science Direct, ProQuest, Health Business Elite, British Nursing Index, Embase, Health Management Information Consortium and PsychInfo. All papers were read and subject to a quality assessment. The literature search identified 95 unique sources. A lack of research on The Productive Ward programme meant it was necessary to include non-empirical literature. In total, 18 articles met the inclusion criteria. Seven key themes were identified: the patient and staff experience, direct care time, patient safety, financial impact, embedding and sustainability, executive support and leadership, and common barriers and determinants of success. It also highlighted areas that require further exploration such as long-term sustainability of the programme and consistent data measurement between organisations. The review tentatively reports how The Productive Ward programme has been used to transform nursing practice for the benefit of patients and frontline staff, and how it resulted in cost savings. The literature review identified a potential positive results bias in the current literature whereby favourable outcomes were reported. This paper summarises the types of evidence and current literature on The Productive Ward providing a reference for frontline staff implementing the programme. © 2013 Blackwell Publishing Ltd.

Mental illness, mass shootings, and the politics of American firearms.

Science.gov (United States)

Metzl, Jonathan M; MacLeish, Kenneth T

2015-02-01

Four assumptions frequently arise in the aftermath of mass shootings in the United States: (1) that mental illness causes gun violence, (2) that psychiatric diagnosis can predict gun crime, (3) that shootings represent the deranged acts of mentally ill loners, and (4) that gun control "won't prevent" another Newtown (Connecticut school mass shooting). Each of these statements is certainly true in particular instances. Yet, as we show, notions of mental illness that emerge in relation to mass shootings frequently reflect larger cultural stereotypes and anxieties about matters such as race/ethnicity, social class, and politics. These issues become obscured when mass shootings come to stand in for all gun crime, and when "mentally ill" ceases to be a medical designation and becomes a sign of violent threat.

Violent video game effects on children and adolescents. A review of the literature.

Science.gov (United States)

Gentile, D A; Stone, W

2005-12-01

Studies of violent video games on children and adolescents were reviewed to: 1) determine the multiple effects; 2) to offer critical observations about common strengths and weaknesses in the literature; 3) to provide a broader perspective to understand the research on the effects of video games. The review includes general theoretical and methodological considerations of media violence, and description of the general aggression model (GAM). The literature was evaluated in relation to the GAM. Published literature, including meta-analyses, are reviewed, as well as relevant unpublished material, such as conference papers and dissertations. Overall, the evidence supports hypotheses that violent video game play is related to aggressive affect, physiological arousal, aggressive cognitions, and aggressive behaviours. The effects of video game play on school performance are also evaluated, and the review concludes with a dimensional approach to video game effects. The dimensional approach evaluates video game effects in terms of amount, content, form, and mechanics, and appears to have many advantages for understanding and predicting the multiple types of effects demonstrated in the literature.

2018-01-01

The majority of the reviews and studies on chronic pain in pregnancy have primarily focused on the pharmacological and non-pharmacological treatment options. The purpose of our review was to identify evidence-based clinical research for the evaluation and management of preexisting chronic pain in pregnancy, chronic pain associated with pregnancy, and chronic pain in relation to mode of delivery. A literature search was undertaken using the search engines PubMed, CINAHL, EBSCOhost, and Web of Science. Search terms used included "chronic pain" AND "pregnant OR pregnancy" OR "pregnancy complications" from inception through August 2016. The basis of this review was the 144 articles that met inclusion criteria for this review. Based on our review of the current literature, we recommend 7 guidelines for chronic pain management during and after pregnancy: 1) complete history and physical examination; 2) monitor patients for alcohol, nicotine, and substance use; 3) collaborate with patient to set treatment goals; 4) develop a management plan; 5) for opioids, use lowest effective dose; 6) formulate a pain management plan for labor and delivery; and 7) discuss reproductive health with women with chronic pain. The management of chronic pain associated with pregnancy is understudied. Obstetrical providers primarily manage chronic pain during pregnancy. Some general guidelines are provided for those health care providers until more information is available.

Role of antioxidants in disease and cancer prevention: a literature review

International Nuclear Information System (INIS)

Ahmed, I.; Ishtiaq, S.

2015-01-01

This review was written on data collected from, review articles, cross-sectional studies, randomized control trials, open-label studies, critical reviews, Cochrane data base system reviews, meta-analysis, population based trials, different phase-I and phase-II trials reported in literature between 1993 to 2014. Web sites and other online resources of Medline, NCBI, Pub med, Medscape resource centers, American college of surgeons were used to extract the data. The debate about the role of antioxidant therapy in disease or cancer prevention has long-loomed. Oxidative damage induced by free radicals has been implicated in most inflammatory and degenerative diseases. Scientific research has reported that the antioxidants may have a role in carcinogenesis, while antioxidant-containing fruits, vegetables may protect against some of these diseases while the role of supplements containing antioxidants in the prevention of chronic diseases remains unproven. This review provides basic information about antioxidants and summarizes different studies reported in literature about the role antioxidants in disease or cancer prevention. (author)

Readiness factors for lean implementation in healthcare settings--a literature review.

Science.gov (United States)

Al-Balushi, S; Sohal, A S; Singh, P J; Al Hajri, A; Al Farsi, Y M; Al Abri, R

2014-01-01

The purpose of this paper is to determine the readiness factors that are critical to the application and success of lean operating principles in healthcare organizations through a review of relevant literature. A comprehensive review of literature focussing on lean and lean healthcare was conducted. Leadership, organizational culture, communication, training, measurement, and reward systems are all commonly attributed readiness factors throughout general change management and lean literature. However, directly related to the successful implementation of lean in healthcare is that a setting is able to authorize a decentralized management style and undertake an end-to-end process view. These can be particularly difficult initiatives for complex organizations such as healthcare settings. The readiness factors identified are based on a review of the published literature. The external validity of the findings could be enhanced if tested using an empirical study. The readiness factors identified will enable healthcare practitioners to be better prepared as they begin their lean journeys. Sustainability of the lean initiative will be at stake if these readiness factors are not addressed. To the best of the knowledge, this is the first paper that provides a consolidated list of key lean readiness factors that can guide practice, as well as future theory and empirical research.

The evolutionary development of pharmaceutical transformation was studied through systematic review of the literature. Fourteen triggers were identified that will affect the pharmaceutical business, regulatory science, and enabling technologies in future years. The relative importance ranking of the transformation triggers was computed based on their prevalence within the articles studied. The four main triggers with the strongest literature evidence were Fully Integrated Pharma Network, Personalized Medicine, Translational Research, and Pervasive Computing. The theoretical quality risks for each of the four main transformation triggers are examined, and the remaining ten triggers are described. The pharmaceutical industry is currently going through changes that affect the way it performs its research, manufacturing, and regulatory activities (this is termed pharmaceutical transformation). The impact of these changes on the approaches to quality risk management requires more understanding. In this paper, a comprehensive review of the academic, regulatory, and industry literature were used to identify 14 triggers that influence pharmaceutical transformation. The four main triggers, namely Fully Integrated Pharma Network, Personalized Medicine, Translational Research, and Pervasive Computing, were selected as the most important based on the strength of the evidence found during the literature review activity described in this paper. Theoretical quality risks for each of the four main transformation triggers are examined, and the remaining ten triggers are described.

Barker, Emma; Kolves, Kairi; De Leo, Diego

2017-09-01

Rail-related suicide is a relatively rare but extremely lethal method of suicide that can have far-reaching consequences. The aim of the systematic literature review was to analyze the existing literature on the effectiveness of rail-suicide prevention activities. Databases used were Scopus, Medline, and ProQuest. The search terms used were "suicid*," "prevent*," "rail*," or "train." English-language studies published in peer-reviewed journals between 1 January 1990 and 30 April 2015 that presented an overview of rail-related suicide prevention activities and included an analysis of effectiveness were used. We retrieved 1,229 results in the original search with nine papers presenting empirical evidence. Three studies in the review analyzed the effectiveness of platform screen doors and another three analyzed the installation of blue lights, two papers analyzed the effectiveness of suicide pits, and one included the influence of media reporting guidelines. Platform screen doors, suicide pits, blue lights, and improved media guidelines all have the potential to reduce rail-related suicide events and deaths. The review was restricted to English-language peer-reviewed papers published within the chosen time period. © 2016 John Wiley & Sons Australia, Ltd.

The study aimed to investigate the scientific literature on Public Humanization Policies, available in online periodicals, from 2009 to 2012, in the health field. This is an integrative literature review conducted in the Virtual Health Library databases: Latin-America and Caribbean Health Sciences (Lilacs) and the Scientific Electronic Library Online (SciELO) and Portal Capes. Data were collected in July 2013. To this end, the following Health Sciences Descriptors (DeCS) were used: "Humanization of Care," "Public Policies," "National Humanization Policy". The sample consisted of 27 articles about the investigated theme. From the publications selected for the research, three categories emerged according to their respective approaches: National Human-ization Policy: history and processes involved in its implementation; National Humanization Policy: health professionals contribution; Humanization and in the care process. The study showed that the National Humanization Policy is an important benchmark in the development of health practices. For this reason, there is a pressing multiplication of related reflections on ways to promote human-ization in health services.

Morphological Evaluation of Shoots Regenerated from Hygromycin-Resistant Rice Callus (cv IACuba-28

Directory of Open Access Journals (Sweden)

Maylin Pérez Bernal

2007-01-01

Full Text Available An evaluation system based on the morphological characteristics of regenerated hygromycin-resistant rice callus shoots was established for correlating such characteristics with shoot viability on hygromycin. Embryogenic rice calli were transformed by Agrobacterium tumefaciens (EHA105/ pCAMBIA1300, containing the hygromycin-phosphotransferase gene as selection marker. After two weeks on selection medium, hygromycin-resistant calli were transferred to regeneration medium. Regenerated shoots were extracted every 5 days (over a 30-day period and classified into three classes according to their morphological structure: class I: vigorous shoot having typical bipolar structure; class II: shoot having small root compared to apical length, or shoot without roots; class III: shoots having an abnormal appearance, such as malformed leaves or albinism. Individualised shoots were transferred to MS medium containing hygromycin for evaluating their resistance to antibiotics. A relationship was observed between regenerated shoots’ morphological characteristics and the percentage of shoots’ viability on hygromycin. Class I prevailed at early shoot extraction and was the most resistant to hygromycin. Drastic class I reduction was found with later shoot extraction, whilst classes II and III became increased. Likewise, shoot viability became radically reduced on MS medium containing hygromycin. This result might be applied for improving efficiency regarding obtaining transgenic rice plants, taking into account the best time for obtaining high percentages of hygromycin-resistant shoots having the best morphological characteristics.

2016-07-01

Proper design has become a critical element needed to engage website and mobile application users. However, little research has been conducted to define the specific elements used in effective website and mobile application design. We attempt to review and consolidate research on effective design and to define a short list of elements frequently used in research. The design elements mentioned most frequently in the reviewed literature were navigation, graphical representation, organization, content utility, purpose, simplicity, and readability. We discuss how previous studies define and evaluate these seven elements. This review and the resulting short list of design elements may be used to help designers and researchers to operationalize best practices for facilitating and predicting user engagement.

Attracting and maintaining the Y Generation in nursing: a literature review.

Hutchinson, Dianne; Brown, Janie; Longworth, Karen

2012-05-01

This paper explores the literature related to attracting the Y Generation (Y Gen: people born between 1980 and 2000) to the nursing profession and retaining them in our current workforce. A comprehensive review of the literature supported the need for further research. Three searches were conducted and all relevant literature was reviewed by each researcher. Literature included in the review was chosen based on specific search-term inclusion. Structured searches were conducted with no limitations on publication type, date or language. Search engines used included: Australian Family and Society, CINAHL, Expanded Academic, Google Scholar, Medline, ProQuest and PubMed. A critical review of the literature, particularly empirical work on the subject has informed decision making regarding the research questions that remain to be explored. The literature revealed that the Y Gen is currently contributing to the nursing workforce demographics. Much discussion exists surrounding the integration of the Y Gen into the workplace along with the other three generations of nurses. There is also an abundance of descriptions of the Y Gen characteristics and values. There is, however, limited reference relating to what attracted this generation to nursing or what might retain them in the nursing workforce. The Y Gen is the largest generation to enter our workforce since the Baby Boomers. Health services need to recognize the needs of the Y Gen nurses and develop strategies to move the profession forward by preparing the current workforce and environment for a generation that is already here. The focus should be on their strengths with development made to structure a workforce that will support the Y Gen in their professional nursing role. Understanding what attracts the Y Gen to nursing, what managers can do to retain the Y Gen in nursing and how the nursing profession can support the Y Gen to assume a role in nursing and nursing governance will ensure that the retiring generation

2016-01-01

Full Text Available The construction industry is well known as a highly risk prone industry owing to the complexity of its activities and dynamic project environments generating an atmosphere of risks that must be taken into consideration in the decision process. For this reason, we have developed this treatise to elucidate the fundamentals of risk management through a concise new proposal of literature review for risk management in construction. Our explanation of this is venture is that over the years, this area has been acknowledged as a crucial process in the business institutions and the most discussed subject among experts and researchers in the construction sector. We have tried in this report to present the most recent studies considering the impossibility to present all definitions of the concept of risk. This study is mainly a literature review; it looks at the literature relating to the concept of risk, risk management in construction as well as methods used in construction industry.

Mass shootings are common in the United States. They are the most visible form of firearm violence. Their effect on personal decisions to purchase firearms is not well-understood. To determine changes in handgun acquisition patterns after the mass shootings in Newtown, Connecticut, in 2012 and San Bernardino, California, in 2015. Time-series analysis using seasonal autoregressive integrated moving-average (SARIMA) models. California. Adults who acquired handguns between 2007 and 2016. Excess handgun acquisitions (defined as the difference between actual and expected acquisitions) in the 6-week and 12-week periods after each shooting, overall and within subgroups of acquirers. In the 6 weeks after the Newtown and San Bernardino shootings, there were 25 705 (95% prediction interval, 17 411 to 32 788) and 27 413 (prediction interval, 15 188 to 37 734) excess acquisitions, respectively, representing increases of 53% (95% CI, 30% to 80%) and 41% (CI, 19% to 68%) over expected volume. Large increases in acquisitions occurred among white and Hispanic persons, but not among black persons, and among persons with no record of having previously acquired a handgun. After the San Bernardino shootings, acquisition rates increased by 85% among residents of that city and adjacent neighborhoods, compared with 35% elsewhere in California. The data relate to handguns in 1 state. The statistical analysis cannot establish causality. Large increases in handgun acquisitions occurred after these 2 mass shootings. The spikes were short-lived and accounted for less than 10% of annual handgun acquisitions statewide. Further research should examine whether repeated shocks of this kind lead to substantial increases in the prevalence of firearm ownership. None.

Franzese, O

2004-09-22

This paper provides a review of examples from the literature of shared communication resources and of agencies and/or organizations that share communication resources. The primary emphasis is on rural, intelligent transportation system communications involving transit. Citations will not be limited, however, to rural activities, or to ITS implementation, or even to transit. In addition, the term ''communication'' will be broadly applied to include all information resources. Literature references to issues that contribute to both successful and failed efforts at sharing communication resources are reviewed. The findings of this literature review indicate that: (1) The most frequently shared communication resources are information/data resources, (2) Telecommunications infrastructure and technologies are the next most frequently shared resources, (3) When resources are successfully shared, all parties benefit, (4) A few unsuccessful attempts of sharing resources have been recorded, along with lessons learned, (5) Impediments to sharing include security issues, concerns over system availability and reliability, service quality and performance, and institutional barriers, (6) Advantages of sharing include financial benefits to agencies from using shared resources and benefits to the public in terms of congestion mitigation, information transfer (e.g., traveler information systems), mobility (e.g., welfare-to-work paratransit), and safety (e.g., speed of incident response, incident avoidance), (7) Technology-based solutions exist to address technology-based concerns, and (8) Institutional issues can be addressed through leadership, enhanced knowledge and skills, open communication, responsiveness, and attractive pricing structures.

The Role of Google Scholar in Evidence Reviews and Its Applicability to Grey Literature Searching

Science.gov (United States)

Haddaway, Neal Robert; Collins, Alexandra Mary; Coughlin, Deborah; Kirk, Stuart

2015-01-01

Google Scholar (GS), a commonly used web-based academic search engine, catalogues between 2 and 100 million records of both academic and grey literature (articles not formally published by commercial academic publishers). Google Scholar collates results from across the internet and is free to use. As a result it has received considerable attention as a method for searching for literature, particularly in searches for grey literature, as required by systematic reviews. The reliance on GS as a standalone resource has been greatly debated, however, and its efficacy in grey literature searching has not yet been investigated. Using systematic review case studies from environmental science, we investigated the utility of GS in systematic reviews and in searches for grey literature. Our findings show that GS results contain moderate amounts of grey literature, with the majority found on average at page 80. We also found that, when searched for specifically, the majority of literature identified using Web of Science was also found using GS. However, our findings showed moderate/poor overlap in results when similar search strings were used in Web of Science and GS (10–67%), and that GS missed some important literature in five of six case studies. Furthermore, a general GS search failed to find any grey literature from a case study that involved manual searching of organisations’ websites. If used in systematic reviews for grey literature, we recommend that searches of article titles focus on the first 200 to 300 results. We conclude that whilst Google Scholar can find much grey literature and specific, known studies, it should not be used alone for systematic review searches. Rather, it forms a powerful addition to other traditional search methods. In addition, we advocate the use of tools to transparently document and catalogue GS search results to maintain high levels of transparency and the ability to be updated, critical to systematic reviews.

Full Text Available The debate over the place and role of literature in language classrooms has long intrigued researchers and teachers’ interests over the years. Although there is an overall consensus that the teaching of literature in English language teaching (ELT classrooms can help foster L2 learners’ language skills and cognitive abilities, some researchers have suggested that integrating literature in ELT classrooms should be approached with caution due to EFL learners’ limited language proficiency. In this paper, the researcher reviews previous related studies on the place of literature in the English language teaching (ELT contexts. The aim of this review is to shed light on this researchers/teachers’ ongoing debate over the place of teaching English literature in ELT. In particular, the review examines how researchers perceive the role of literature and its authenticity in ELT classrooms as stimulating learners’ interests and personal engagement with literary texts, fostering L2 learners’ language skills (particularly their reading and creative writing skills, and enhancing their critical thinking skills and strategic processing of texts. Furthermore, the review covers issues related to how the integration of literature in language classrooms should be carefully task-designed and assessed.

Diabetes is a major public health problem worldwide. Depression is a serious mental condition that decreases mental and physical functioning and reduces the quality of life. Several lines of evidence suggest a bidirectional relationship between diabetes and depression: diabetes patients are twice as likely to experience depression than nondiabetic individuals. In contrast, depression increases the risk of diabetes and interferes with its daily self-management. Diabetes patients with depression have poor glycemic control, reduced quality of life, and an increased risk of diabetes complications, consequently having an increased mortality rate. Conflicting evidence exists on the potential role of factors that may account for or modulate the relationship between diabetes and depression. Therefore, this review aims to highlight the most notable body of literature that dissects the various facets of the bidirectional relationship between diabetes and depression. A focused discussion of the proposed mechanisms underlying this relationship is also provided. We systematically reviewed the relevant literature in the PubMed database, using the keywords "Diabetes AND Depression". After exclusion of duplicate and irrelevant material, literature eligible for inclusion in this review was based on meta-analysis studies, clinical trials with large sample sizes (n≥1,000), randomized clinical trials, and comprehensive national and cross-country clinical studies. The evidence we present in this review supports the pressing need for long, outcome-oriented, randomized clinical trials to determine whether the identification and treatment of patients with these comorbid conditions will improve their medical outcomes and quality of life.

Spaceflight and Neurosurgery: A Comprehensive Review of the Relevant Literature.

Swinney, Christian C; Allison, Zain

2018-01-01

Spaceflight and the associated gravitational fluctuations may impact various components of the central nervous system. These include changes in intracranial pressure, the spine, and neurocognitive performance. The implications of altered astronaut performance on critical spaceflight missions are potentially significant. The current body of research on this important topic is extremely limited, and a comprehensive review has not been published. Herein, the authors address this notable gap, as well as the role of the neurosurgeon in optimizing potential diagnostic and therapeutic modalities. A literature search was conducted using the PubMed, EMBASE, and Google Scholar databases, with no time constraints. Significant manuscripts on physiologic changes associated with spaceflight and microgravity were identified and reviewed. Manifestations were separated into 1 of 3 general categories, including changes in intracranial pressure, the spine, and neurocognitive performance. A comprehensive literature review yielded 27 studies with direct relevance to the impact of microgravity and spaceflight on nervous system physiology. This included 7 studies related to intracranial pressure fluctuations, 17 related to changes in the spinal column, and 3 related to neurocognitive change. The microgravity environment encountered during spaceflight impacts intracranial physiology. This includes changes in intracranial pressure, the spinal column, and neurocognitive performance. Herein, we present a systematic review of the published literature on this issue. Neurosurgeons should have a key role in the continued study of this important topic, contributing to both diagnostic and therapeutic understanding. Copyright © 2017 Elsevier Inc.

Full Text Available Despite an increasing literature related to elder abuse, sexual abuse of older persons in general and of vulnerable adults living in nursing homes in particular is still sparsely described. The purpose of this study was to assess the state of knowledge on the subject of sexual abuse against older nursing home residents through a literature review. Systematic searches in reference databases including Cinahl, Medline, OVID Nursing Database, ISI Web of Science, PsycINFO, Cochrane Library, and SveMed + were conducted. Through several phases of selection of the articles, using strict inclusion and exclusion criteria, six articles were chosen for a deeper examination. Findings from the review show that sexual abuse occurs in nursing homes and that both older women and men are victims of sexual abuse. Perpetrators appear mainly to be staff and other residents and mainly to be men, but also women abuse both older men and older women. Findings from the literature review show that there is a need for knowledge and further research on the topic of sexual abuse against older residents in nursing homes. Furthermore, there is a need for good policies and reporting systems, as an important step in seriously addressing sexual abuse against older persons.
