  1. The structure of observed learning outcome (SOLO) taxonomy: a model to promote dental students' learning. (United States)

    Lucander, H; Bondemark, L; Brown, G; Knutsson, K


    Selective memorising of isolated facts or reproducing what is thought to be required - the surface approach to learning - is not the desired outcome for a dental student or a dentist in practice. The preferred outcome is a deep approach as defined by an intention to seek understanding, develop expertise and relate information and knowledge into a coherent whole. The aim of this study was to investigate whether the structure of observed learning outcome (SOLO) taxonomy could be used as a model to assist and promote the dental students to develop a deep approach to learning assessed as learning outcomes in a summative assessment. Thirty-two students, participating in course eight in 2007 at the Faculty of Odontology at Malmö University, were introduced to the SOLO taxonomy and constituted the test group. The control group consisted of 35 students participating in course eight in 2006. The effect of the introduction was measured by evaluating responses to a question in the summative assessment by using the SOLO taxonomy. The evaluators consisted of two teachers who performed the assessment of learning outcomes independently and separately on the coded material. The SOLO taxonomy as a model for learning was found to improve the quality of learning. Compared to the control group significantly more strings and structured relations between these strings were present in the test group after the SOLO taxonomy had been introduced (P SOLO taxonomy is recommended as a model for promoting and developing a deeper approach to learning in dentistry.

    Ilgüy, Mehmet; Ilgüy, Dilhan; Fişekçioğlu, Erdoğan; Oktay, Inci


    The aim of this study was to compare the impact of case-based learning (CBL) and lecture-based learning (LBL) on fourth-year dental students' clinical decision making by using the Structure of Observed Learning Outcome (SOLO) taxonomy. Participants in the study were fourth-year dental students (n=55) in academic year 2012-13 taught in a large-group LBL context and fourth-year dental students (n=54) in academic year 2013-14 taught with the CBL methodology; both took place in the oral diseases course at Yeditepe University Faculty of Dentistry, Istanbul, Turkey. All eligible students participated, for a 100 percent response rate. A real case was presented to the students in both groups to assess their clinical decision making on the topic of oral diseases. Their performance was evaluated with the SOLO taxonomy. Student t-test was used for statistical evaluation, and significance was set at the pSOLO taxonomy than students taught with LBL. These findings suggest that an integrated case-based curriculum may be effective in promoting students' deep learning and it holds promise for better integration of clinical cases likely to be encountered during independent practice.

  11. Academicians and Neurologic Physical Therapy Residents Partner to Expand Clinical Reflection Using the SOLO Taxonomy: A Novel Approach. (United States)

    Pinto Zipp, Genevieve; Maher, Catherine; Donnelly, Erin; Fritz, Brian; Snowdon, Lauren


    Creating curriculums that develop physical therapy (PT) students into evidenced-based, critically reflective, entry-level practitioners is one of the primary goals for PT programs. Academic faculty partnering with neurologic residency programs to design learning environments that capitalize upon the strengths of both can create insightful educational experiences for students during their didactic training. These partnerships support the development of critical thinking skills and provide mentorship for residents transitioning from their role as a clinician to that of an educator. Using the SOLO (structure of observed learning outcomes) taxonomy as a framework for developing learning experiences, Seton Hall University neurologic academic faculty and program directors from the Kessler Institute for Rehabilitation Residency in Neurologic Physical Therapy have built a partnership that seeks to develop critical reflection skills in both the neurologic resident and entry-level PT students. While integration of residents into entry-level PT curriculum may not be novel, we believe that utilizing the SOLO model within this partnership is unique. This paper describes the partnership and learning experiences rooted in the SOLO taxonomy theoretical framework and discusses perceived benefits of this learning experience across professional health science programs.

    This study aims to determine the extent to which the students ‘thinking level based on SOLO taxonomy in geometry learning viewed from students’ self efficacy (SE). This research utilizes descriptive research with qualitative approach. The data was collected by giving SE questionnaires to 32 students of grade VIII Junior High School which were then categorized into three (high, medium, and low). The subjects of the study were taken by one student in each SE category (high, medium, and low) which then given the problem solving test and the result was triangulated by interview. From this research, it is found that students with high SE can achieve uniructural-relational thinking level, subject with medium SE can be reach the level of unistructural-multistructural thinking, and subject with low SE able to reach unistructural-pristructural level. By paying attention to SE in learning, especially in problem solving process, it is expected that the educator can prepare the learning as well as possible so as to obtain optimal learning achievement.

  17. Offending, Adjudication, and Outcome Patterns of Solo Male, Solo Female, and Partnered Mass Murderers. (United States)

    Gurian, Elizabeth A


    Research on mass murder is limited due to differences in definitions (particularly with respect to victim count), as well as categorizations based on motive. These limitations restrict our understanding of the offending, adjudication, and outcome patterns of these offenders and can obscure potential underlying similarities to comparable types of offenders (e.g., lone actors or terrorists). To address some of these limitations, this research study, which includes an international sample of 434 cases (455 total offenders), uses descriptive and empirical analyses of solo male, solo female, and partnered mass murderers (teams of two or more) to explore offending, adjudication, and outcome patterns among these different types offenders. While the results from this research study support much previous mass murder research, the findings also emphasize the importance of large international sample sizes, objective categorizations, and the use of empirically based analyses to further advance our understanding of these offenders.

  18. DNA barcodes for soil animal taxonomy Código de barras de DNA para a taxonomia de animais do solo

    Directory of Open Access Journals (Sweden)

    Rodolphe Rougerie


    Full Text Available The biodiversity of soil communities remains very poorly known and understood. Soil biological sciences are strongly affected by the taxonomic crisis, and most groups of animals in that biota suffer from a strong taxonomic impediment. The objective of this work was to investigate how DNA barcoding - a novel method using a microgenomic tag for species identification and discrimination - permits better evaluation of the taxonomy of soil biota. A total of 1,152 barcode sequences were analyzed for two major groups of animals, collembolans and earthworms, which presented broad taxonomic and geographic sampling. Besides strongly reflecting the taxonomic impediment for both groups, with a large number of species-level divergent lineages remaining unnamed so far, the results also highlight a high level (15% of cryptic diversity within known species of both earthworms and collembolans. These results are supportive of recent local studies using a similar approach. Within an impeded taxonomic system for soil animals, DNA-assisted identification tools can facilitate and improve biodiversity exploration and description. DNA-barcoding campaigns are rapidly developing in soil animals and the community of soil biologists is urged to embrace these methods.A biodiversidade das comunidades do solo continua muito pouco conhecida e entendida. A biologia do solo é fortemente afetada pela crise taxonômica, e a maior parte dos grupos de animais dessa biota sofre forte impedimento taxonômico.

    Full Text Available Objectives. To design a series of e-learning tools within the framework of a defined educational pedagogy to complement the conventional pharmacology curriculum at Griffith University and evaluate the impact of this strategy on student level of understanding through taxonomic classification of student final exam answers. Methods. A series of 148 e-learning tools was designed for 3rd year undergraduate pharmacy students and incorporated into their curriculum during 2012. The educational benefits of the e-learning tools were evaluated by analyses of student level of understanding (by SOLO taxonomy at the final exams between the control group (standard curricula in 2011 and the intervention group (standard curricula + e-learning tools in 2012. Results. Backward linear regression analysis demonstrated GPA to be the most significant predictor of level of understanding, while the intervention group was a highly significant predictor for greater level of understanding in semester two. Conclusion. E-learning tools appeared to significantly improve student level of understanding as scored by the SOLO taxonomy when students engaged highly with the tools.

  1. Analysing learning outcomes in an Electrical Engineering curriculum using illustrative verbs derived from Bloom's Taxonomy (United States)

    Meda, Lawrence; Swart, Arthur James


    Learning outcomes are essential to any curriculum in education, where they need to be clear, observable and measurable. However, some academics structure learning outcomes in a way that does not promote student learning. The purpose of this article is to present the analyses of learning outcomes of an Electrical Engineering curriculum offered at a University of Technology in South Africa, in order to determine if academics are structuring them in a way that enables student learning. A qualitative case study is used where the learning outcomes from 33 study guides are reviewed using illustrative verbs derived from Bloom's Taxonomy. Results indicate that 9% of all the learning outcomes are unclear, 10% are unobservable and 23% are unmeasurable. A key recommendation is to provide regular workshops to assist academics in reviewing their learning outcomes using the illustrative verbs derived from Bloom's Taxonomy, thereby ensuring that their learning outcomes promote student learning.

  2. A new taxonomy for stakeholder engagement in patient-centered outcomes research. (United States)

    Concannon, Thomas W; Meissner, Paul; Grunbaum, Jo Anne; McElwee, Newell; Guise, Jeanne-Marie; Santa, John; Conway, Patrick H; Daudelin, Denise; Morrato, Elaine H; Leslie, Laurel K


    Despite widespread agreement that stakeholder engagement is needed in patient-centered outcomes research (PCOR), no taxonomy exists to guide researchers and policy makers on how to address this need. We followed an iterative process, including several stages of stakeholder review, to address three questions: (1) Who are the stakeholders in PCOR? (2) What roles and responsibilities can stakeholders have in PCOR? (3) How can researchers start engaging stakeholders? We introduce a flexible taxonomy called the 7Ps of Stakeholder Engagement and Six Stages of Research for identifying stakeholders and developing engagement strategies across the full spectrum of research activities. The path toward engagement will not be uniform across every research program, but this taxonomy offers a common starting point and a flexible approach.

    The Solo Smart pericardial aortic valve has been widely used in Europe as an option for aortic valve replacement (AVR). We are reporting early and midterm clinical outcomes of AVR with the Solo Smart valve in a single North America center. This is a retrospective study of 270 consecutive patients who had AVR at Mazankowski Alberta Heart Institute from February 2011 to March 2015. Follow-up and echocardiographic data were collected retrospectively from electronic and paper charts. Univariate and multivariate analysis were performed to evaluate the results. The mean age was 71.2±10.0 years, 67.4% were male, and 79.3% had combined procedures. Mean STS Score was 4.18±3.91. Early mortality was 3.7% for the entire group and 0% for isolated aortic valve replacement group. Mean cross-clamp time for isolated AVR and AVR with concomitant procedure was 70.8±12.7min and 117.0±45.0min, respectively. Permanent pacemaker implantation was necessary in 2.2% of patients. Echocardiography demonstrated a reduction in mean gradients from 40.8±17.4mmHg to 7.6±3.7 mmHg and peak gradient from 72.5 ± 48.8 mmHg to 15.5±7.5 mmHg. The 1-, 3-, and 5- year overall survival was 93.0%, 86.5% and 75.9%, respectively. At 5 years, freedom from valve-related death was 92.4%, freedom from structural valve deterioration and freedom from aortic valve reoperation were 96.4% and 98%, respectively. The Solo Smart valve is safe and has excellent hemodynamic performance. Aortic valve reoperation and rates of valve-related adverse events during midterm follow-up were low.

    Christ, Torsten; Claus, Benjamin; Zielinski, Christina; Falk, Volkmar; Grubitzsch, Herko


    The Sorin Freedom SOLO valve is a third-generation stentless aortic valve which shows beneficial hemodynamic performance compared to stented bioprostheses. Long-term results regarding hemodynamics, the durability of the valve, and patient outcome are scarce, and their acquisition was the aim of this single-center study. Between 2005 and 2006, a total of 68 consecutive patients (30 males, 38 females; mean age at surgery 76.1 ± 6.3 years) underwent aortic valve replacement with a Sorin Freedom SOLO prosthesis. Indications were aortic stenosis (n = 50), aortic regurgitation (n = 1) and mixed lesions (n = 17). Associated procedures were performed in 31 patients (45.6%), most of which were coronary artery bypass grafting (68.8 %). The follow up was performed by telephone interviews, and clinical and echocardiographic examinations. Morbidity, mortality and echocardiographic data were analyzed. The total follow up was 501.1 patient-years, with a mean follow up of 7.4 ± 3.4 years (maximum 11.2 years). The follow up was 100% complete. Hospital mortality was 4.4% (n = 3). Actuarial survival at five and 10 years was 76.5 ± 5.1% and 41.5 ± 6.5%, respectively. Reinterventions were performed in eight patients; these included three reoperations due to endocarditis, four transcatheter aortic valve implantations, and one reoperation due to structural valve deterioration (SVD). The overall freedom from valve reintervention due to SVD at five and 10 years was 97.8 ± 2.2% and 82.9 ± 7.5%, respectively. After eight years, echocardiography demonstrated peak and mean transvalvular gradients of 18 ± 11 and 10 ± 7 mmHg, respectively. The overall effective and indexed aortic valve orifice areas were 1.73 ± 0.58 cm2 and 0.92 ± 0.33 cm2/m2, respectively. At long-term follow up the Sorin Freedom SOLO bioprosthesis was associated with favourable hemodynamic results and survival. Freedom from SVD was not superior to that occurring with stented bioprostheses.

  7. Antecedents and outcomes of a fourfold taxonomy of work-family balance in Chinese employed parents. (United States)

    Lu, Jia-Fang; Siu, Oi-Ling; Spector, Paul E; Shi, Kan


    The study provided validity evidence for a fourfold taxonomy of work-family balance that comprises direction of influence (work to family vs. family to work) and types of effect (work-family conflict vs. work-family facilitation). Data were collected from 189 employed parents in China. The results obtained from a confirmatory factor analysis supported the factorial validity of the fourfold taxonomy of work-family balance with a Chinese sample. Child care responsibilities, working hours, monthly salary, and organizational family-friendly policy were positively related to the conflict component of work-family balance; whereas new parental experience, spouse support, family-friendly supervisors and coworkers had significant positive effects on the facilitation component of work-family balance. In comparison with the inconsistent effects of work-family conflict, work to family facilitation had consistent positive effects on work and life attitudes. The implications of findings in relation to China and other countries are discussed in the paper.

    Stanger, Olaf; Bleuel, Irina; Gisler, Fabian; Göber, Volkhard; Reineke, Sylvia; Gahl, Brigitta; Aymard, Thierry; Englberger, Lars; Carrel, Thierry; Tevaearai, Hendrik


    To report our institutional experience and long-term results with the Freedom Solo bovine pericardial stentless bioprosthesis (Sorin Group, Saluggia, Italy). Between January 2005 and November 2009, 149 patients (mean age, 73.6 ± 8.7 years; 68 [45.6%] female) underwent isolated (n = 75) or combined (n = 74) aortic valve replacement (AVR) using the Solo in our institution. Follow-up was 100% complete with an average follow-up time of 5.9 ± 2.6 years (maximum, 9.6 years) and a total of 885.3 patient years. Operative (30-day) mortality was 2.7% (1.3% for isolated AVR [n = 1] and 4.0% for combined procedures [n = 3]). All causes of death were not valve-related. Preoperative peak (mean) gradients of 74.2 ± 23.0 mm Hg (48.6 ± 16.3 mm Hg) decreased to 15.6 ± 5.4 mm Hg (8.8 ± 3.0 mm Hg) after AVR, and remained low for up to 9 years. The postoperative effective orifice area was 1.6 ± 0.57 cm(2), 1.90 ± 0.45 cm(2), 2.12 ± 0.48 cm(2), and 2.20 ± 0.66 cm(2) for the valve sizes 21, 23, 25, and 27, respectively, with absence of severe prosthesis-patient mismatch and 0.7% (n = 1) experienced moderate prosthesis-patient mismatch. During follow-up, 26 patients experienced structural valve deterioration (SVD) and 14 patients underwent explantation. Kaplan-Meier estimates for freedom from death, explantation, and SVD at 9 years averaged 0.57 (range, 0.47-0.66), 0.82 (range, 0.69-0.90), and 0.70 (range, 0.57-0.79), respectively. The Freedom Solo stentless aortic valve is safe to implant and shows excellent early and midterm hemodynamic performance. However, SVD was observed in a substantial number of patients after only 5-6 years and the need for explantation increased markedly, suggesting low durability.

  10. Linking payment to health outcomes: a taxonomy and examination of performance-based reimbursement schemes between healthcare payers and manufacturers. (United States)

    Carlson, Josh J; Sullivan, Sean D; Garrison, Louis P; Neumann, Peter J; Veenstra, David L


    To identify, categorize and examine performance-based health outcomes reimbursement schemes for medical technology. We performed a review of performance-based health outcomes reimbursement schemes over the past 10 years (7/98-010/09) using publicly available databases, web and grey literature searches, and input from healthcare reimbursement experts. We developed a taxonomy of scheme types by inductively organizing the schemes identified according to the timing, execution, and health outcomes measured in the schemes. Our search yielded 34 coverage with evidence development schemes, 10 conditional treatment continuation schemes, and 14 performance-linked reimbursement schemes. The majority of schemes are in Europe and Australia, with an increasing number in Canada and the U.S. These schemes have the potential to alter the reimbursement and pricing landscape for medical technology, but significant challenges, including high transaction costs and insufficient information systems, may limit their long-term impact. Future studies regarding experiences and outcomes of implemented schemes are necessary. Copyright 2010 Elsevier Ireland Ltd. All rights reserved.

  13. Primary healthcare solo practices: homogeneous or heterogeneous? (United States)

    Pineault, Raynald; Borgès Da Silva, Roxane; Provost, Sylvie; Beaulieu, Marie-Dominique; Boivin, Antoine; Couture, Audrey; Prud'homme, Alexandre


    Introduction. Solo practices have generally been viewed as forming a homogeneous group. However, they may differ on many characteristics. The objective of this paper is to identify different forms of solo practice and to determine the extent to which they are associated with patient experience of care. Methods. Two surveys were carried out in two regions of Quebec in 2010: a telephone survey of 9180 respondents from the general population and a postal survey of 606 primary healthcare (PHC) practices. Data from the two surveys were linked through the respondent's usual source of care. A taxonomy of solo practices was constructed (n = 213), using cluster analysis techniques. Bivariate and multilevel analyses were used to determine the relationship of the taxonomy with patient experience of care. Results. Four models were derived from the taxonomy. Practices in the "resourceful networked" model contrast with those of the "resourceless isolated" model to the extent that the experience of care reported by their patients is more favorable. Conclusion. Solo practice is not a homogeneous group. The four models identified have different organizational features and their patients' experience of care also differs. Some models seem to offer a better organizational potential in the context of current reforms.

  15. Asteroid taxonomy

    International Nuclear Information System (INIS)

    Tholen, D.J.


    The spectral reflectivity of asteroid surfaces over the wavelength range of 0.3 to 1.1 μm can be used to classify these objects onto several broad groups with similar spectral characteristics. The three most recently developed taxonomies group the asteroids into 9, 11 or 14 different classes, depending on the technique used to perform the analysis. The distribution of the taxonomic classes shows that darker and redder objects become more dominant at larger heliocentric distances, while the rare asteroid types are found more frequently among the small objects of the planet-crossing population

  4. A concept taxonomy and an instrument hierarchy: tools for establishing and evaluating the conceptual framework of a patient-reported outcome (PRO) instrument as applied to product labeling claims. (United States)

    Erickson, Pennifer; Willke, Richard; Burke, Laurie


    To facilitate development and evaluation of a PRO instrument conceptual framework, we propose two tools--a PRO concept taxonomy and a PRO instrument hierarchy. FDA's draft guidance on patient reported outcome (PRO) measures states that a clear description of the conceptual framework of an instrument is useful for evaluating its adequacy to support a treatment benefit claim for use in product labeling the draft guidance, however does not propose tools for establishing or evaluating a PRO instrument's conceptual framework. We draw from our review of PRO concepts and instruments that appear in prescription drug labeling approved in the United States from 1997 to 2007. We propose taxonomy terms that define relationships between PRO concepts, including "family,"compound concept," and "singular concept." Based on the range of complexity represented by the concepts, as defined by the taxonomy, we propose nine instrument orders for PRO measurement. The nine orders range from individual event counts to multi-item, multiscale instruments. This analysis of PRO concepts and instruments illustrates that the taxonomy and hierarchy are applicable to PRO concepts across a wide range of therapeutic areas and provide a basis for defining the instrument conceptual framework complexity. Although the utility of these tools in the drug development, review, and approval processes has not yet been demonstrated, these tools could be useful to improve communication and enhance efficiency in the instrument development and review process.

Design/methodology/approach: Through in-depth interviews using the repertory grid technique, the authors explored 15 payers’ perceptions of six payment instruments, including coins, banknotes, debit cards, credit cards, mobile payments, and online banking....... The approach draws heavily on organizational systematics to better understand payers’ choice of payment instruments. Findings: A four-category taxonomy of payments was developed. The authors refer to the taxonomy as the 4Ps: the purchase, the payer, the payment instrument, and the physical technology...... or checks. Research limitations/implications: The findings suggest that payers view payment instruments in a much broader sense, including context, control, or cultural beliefs. Consequently, the authors suggest that researchers try to understand the essence of an innovation before assuming any economic...

    Full Text Available A forte pressão provocada pela expansão urbana desordenada sobre os recursos naturais, principalmente os solos, tem provocado danos, muitas vezes de difícil reparo. A grande concentração populacional em centros urbanos cada vez maiores tem dirigido a atenção de diferentes profissionais para o recurso solo, no sentido de entender sua dinâmica para minimizar sua degradação. No entanto, a falta de conhecimento sobre as propriedades, bem como sobre a aptidão dos solos sob uso urbano tem provocado o seu mau uso, resultando em processos como compactação, erosão, deslizamentos e inundações, assim como poluição com substâncias orgânicas, inorgânicas e patógenos, aumentando os custos do desenvolvimento afetando toda a sociedade. Neste sentido, este texto discute como o conhecimento pedológico pode diminuir os efeitos negativos provocados pelo processo de urbanização.The strong pressure caused by the disordered urban expansion over the natural resources, mainly the soils, has caused damages, many times difficult to repair. The great population concentration in urban centers getting larger and larger has been driving the attention of different professionals to soil resource, in the sense of understanding its dynamics to minimize its degradation. The lack of knowledge related to the soils properties and capability promote their inappropriate use, resultig in degrading processes as compaction, erosion, sliding, floods, and organic, inorganic and patogenic pollution, increasing the cost of development and affecting the whole society. This text discusses how pedologic knowledge can reduce the negative effects caused by the urbanization process.

  14. A value-based taxonomy of improvement approaches in healthcare. (United States)

    Colldén, Christian; Gremyr, Ida; Hellström, Andreas; Sporraeus, Daniella


    Purpose The concept of value is becoming increasingly fashionable in healthcare and various improvement approaches (IAs) have been introduced with the aim of increasing value. The purpose of this paper is to construct a taxonomy that supports the management of parallel IAs in healthcare. Design/methodology/approach Based on previous research, this paper proposes a taxonomy that includes the dimensions of view on value and organizational focus; three contemporary IAs - lean, value-based healthcare, and patient-centered care - are related to the taxonomy. An illustrative qualitative case study in the context of psychiatric (psychosis) care is then presented that contains data from 23 interviews and focuses on the value concept, IAs, and the proposed taxonomy. Findings Respondents recognized the dimensions of the proposed taxonomy and indicated its usefulness as support for choosing and combining different IAs into a coherent management model, and for facilitating dialog about IAs. The findings also suggested that the view of value as "health outcomes" is widespread, but healthcare professionals are less likely than managers to also view value as a process. Originality/value The conceptual contribution of this paper is to delineate some important characteristics of IAs in relation to the emerging "value era". It also highlights the coexistence of different IAs in healthcare management practice. A taxonomy is proposed that can help managers choose, adapt, and combine IAs in local management models.

    Iida Tetsuya


    Full Text Available Abstract Background Vibrio taxonomy has been based on a polyphasic approach. In this study, we retrieve useful taxonomic information (i.e. data that can be used to distinguish different taxonomic levels, such as species and genera from 32 genome sequences of different vibrio species. We use a variety of tools to explore the taxonomic relationship between the sequenced genomes, including Multilocus Sequence Analysis (MLSA, supertrees, Average Amino Acid Identity (AAI, genomic signatures, and Genome BLAST atlases. Our aim is to analyse the usefulness of these tools for species identification in vibrios. Results We have generated four new genome sequences of three Vibrio species, i.e., V. alginolyticus 40B, V. harveyi-like 1DA3, and V. mimicus strains VM573 and VM603, and present a broad analyses of these genomes along with other sequenced Vibrio species. The genome atlas and pangenome plots provide a tantalizing image of the genomic differences that occur between closely related sister species, e.g. V. cholerae and V. mimicus. The vibrio pangenome contains around 26504 genes. The V. cholerae core genome and pangenome consist of 1520 and 6923 genes, respectively. Pangenomes might allow different strains of V. cholerae to occupy different niches. MLSA and supertree analyses resulted in a similar phylogenetic picture, with a clear distinction of four groups (Vibrio core group, V. cholerae-V. mimicus, Aliivibrio spp., and Photobacterium spp.. A Vibrio species is defined as a group of strains that share > 95% DNA identity in MLSA and supertree analysis, > 96% AAI, ≤ 10 genome signature dissimilarity, and > 61% proteome identity. Strains of the same species and species of the same genus will form monophyletic groups on the basis of MLSA and supertree. Conclusion The combination of different analytical and bioinformatics tools will enable the most accurate species identification through genomic computational analysis.

    Keeley, Jon E.; Parker, V. Thomas; Vasey, Michael C.


    There is value in understanding the past and how it has affected the present. Science focuses on empirical findings, and we know that our prior experiences and those of our predecessors play important roles in determining how we interpret the present. We learn from accomplishments and foibles of predecessors and appreciate the real life experiences we have gone through. In our studies of the genus Arctostaphylos Adans. we have been struck by the fascinating stories surrounding taxonomists who have played roles in the development of our current understanding of the group. In addition to providing insights, they sometimes provide humor and lessons on the value of competition versus collaboration. We offer this history of the humans that forged the taxonomy behind Arctostaphylos classification in this light.

  1. A taxonomy of inductive problems. (United States)

    Kemp, Charles; Jern, Alan


    Inductive inferences about objects, features, categories, and relations have been studied for many years, but there are few attempts to chart the range of inductive problems that humans are able to solve. We present a taxonomy of inductive problems that helps to clarify the relationships between familiar inductive problems such as generalization, categorization, and identification, and that introduces new inductive problems for psychological investigation. Our taxonomy is founded on the idea that semantic knowledge is organized into systems of objects, features, categories, and relations, and we attempt to characterize all of the inductive problems that can arise when these systems are partially observed. Recent studies have begun to address some of the new problems in our taxonomy, and future work should aim to develop unified theories of inductive reasoning that explain how people solve all of the problems in the taxonomy.

  3. The Distributed Wind Cost Taxonomy

    Energy Technology Data Exchange (ETDEWEB)

    Forsyth, Trudy; Jimenez, Tony; Preus, Robert; Tegen, Suzanne; Baring-Gould, Ian


    To date, there has been no standard method or tool to analyze the installed and operational costs for distributed wind turbine systems. This report describes the development of a classification system, or taxonomy, for distributed wind turbine project costs. The taxonomy establishes a framework to help collect, sort, and compare distributed wind cost data that mirrors how the industry categorizes information. The taxonomy organizes costs so they can be aggregated from installers, developers, vendors, and other sources without losing cost details. Developing a peer-reviewed taxonomy is valuable to industry stakeholders because a common understanding the details of distributed wind turbine costs and balance of station costs is a first step to identifying potential high-value cost reduction opportunities. Addressing cost reduction potential can help increase distributed wind's competitiveness and propel the U.S. distributed wind industry forward. The taxonomy can also be used to perform cost comparisons between technologies and track trends for distributed wind industry costs in the future. As an initial application and piloting of the taxonomy, preliminary cost data were collected for projects of different sizes and from different regions across the contiguous United States. Following the methods described in this report, these data are placed into the established cost categories.

  4. The integrative future of taxonomy

    Directory of Open Access Journals (Sweden)

    Vences Miguel


    Full Text Available Abstract Background Taxonomy is the biological discipline that identifies, describes, classifies and names extant and extinct species and other taxa. Nowadays, species taxonomy is confronted with the challenge to fully incorporate new theory, methods and data from disciplines that study the origin, limits and evolution of species. Results Integrative taxonomy has been proposed as a framework to bring together these conceptual and methodological developments. Here we review perspectives for an integrative taxonomy that directly bear on what species are, how they can be discovered, and how much diversity is on Earth. Conclusions We conclude that taxonomy needs to be pluralistic to improve species discovery and description, and to develop novel protocols to produce the much-needed inventory of life in a reasonable time. To cope with the large number of candidate species revealed by molecular studies of eukaryotes, we propose a classification scheme for those units that will facilitate the subsequent assembly of data sets for the formal description of new species under the Linnaean system, and will ultimately integrate the activities of taxonomists and molecular biologists.

  10. Computational Exploration of Putative LuxR Solos in Archaea and Their Functional Implications in Quorum Sensing (United States)

    Rajput, Akanksha; Kumar, Manoj


    LuxR solos are unexplored in Archaea, despite their vital role in the bacterial regulatory network. They assist bacteria in perceiving acyl homoserine lactones (AHLs) and/or non-AHLs signaling molecules for establishing intraspecies, interspecies, and interkingdom communication. In this study, we explored the potential LuxR solos of Archaea from InterPro v62.0 meta-database employing taxonomic, probable function, distribution, and evolutionary aspects to decipher their role in quorum sensing (QS). Our bioinformatics analyses showed that putative LuxR solos of Archaea shared few conserved domains with bacterial LuxR despite having less similarity within proteins. Functional characterization revealed their ability to bind various AHLs and/or non-AHLs signaling molecules that involve in QS cascades alike bacteria. Further, the phylogenetic study indicates that Archaeal LuxR solos (with less substitution per site) evolved divergently from bacteria and share distant homology along with instances of horizontal gene transfer. Moreover, Archaea possessing putative LuxR solos, exhibit the correlation between taxonomy and ecological niche despite being the inhabitant of diverse habitats like halophilic, thermophilic, barophilic, methanogenic, and chemolithotrophic. Therefore, this study would shed light in deciphering the role of the putative LuxR solos of Archaea to adapt varied habitats via multilevel communication with other organisms using QS.

  12. Team errors: definition and taxonomy

    International Nuclear Information System (INIS)

    Sasou, Kunihide; Reason, James


    In error analysis or error management, the focus is usually upon individuals who have made errors. In large complex systems, however, most people work in teams or groups. Considering this working environment, insufficient emphasis has been given to 'team errors'. This paper discusses the definition of team errors and its taxonomy. These notions are also applied to events that have occurred in the nuclear power industry, aviation industry and shipping industry. The paper also discusses the relations between team errors and Performance Shaping Factors (PSFs). As a result, the proposed definition and taxonomy are found to be useful in categorizing team errors. The analysis also reveals that deficiencies in communication, resource/task management, excessive authority gradient, excessive professional courtesy will cause team errors. Handling human errors as team errors provides an opportunity to reduce human errors

    Rima, Bert; Collins, Peter; Easton, Andrew; Fouchier, Ron; Kurath, Gael; Lamb, Robert A; Lee, Benhur; Maisner, Andrea; Rota, Paul; Wang, Linfa; Ictv Report Consortium


    The family Pneumoviridae comprises large enveloped negative-sense RNA viruses. This taxon was formerly a subfamily within the Paramyxoviridae, but was reclassified in 2016 as a family with two genera, Orthopneumovirus and Metapneumovirus. Pneumoviruses infect a range of mammalian species, while some members of the Metapneumovirus genus may also infect birds. Some viruses are specific and pathogenic for humans, such as human respiratory syncytial virus and human metapneumovirus. There are no known vectors for pneumoviruses and transmission is thought to be primarily by aerosol droplets and contact.

    The family Hepeviridae includes enterically transmitted small non-enveloped positive-sense RNA viruses. It includes the genera Piscihepevirus, whose members infect fish, and Orthohepevirus, whose members infect mammals and birds. Members of the genus Orthohepevirus include hepatitis E virus, which is responsible for self-limiting acute hepatitis in humans and several mammalian species; the infection may become chronic in immunocompromised individuals. Extrahepatic manifestations of Guillain-Barré syndrome, neuralgic amyotrophy, glomerulonephritis and pancreatitis have been described in humans. Avian hepatitis E virus causes hepatitis-splenomegaly syndrome in chickens.

  16. Taxonomy of the extrasolar planet. (United States)

    Plávalová, Eva


    When a star is described as a spectral class G2V, we know that the star is similar to our Sun. We know its approximate mass, temperature, age, and size. When working with an extrasolar planet database, it is very useful to have a taxonomy scale (classification) such as, for example, the Harvard classification for stars. The taxonomy has to be easily interpreted and present the most relevant information about extrasolar planets. I propose an extrasolar planet taxonomy scale with four parameters. The first parameter concerns the mass of an extrasolar planet in the form of units of the mass of other known planets, where M represents the mass of Mercury, E that of Earth, N Neptune, and J Jupiter. The second parameter is the planet's distance from its parent star (semimajor axis) described in a logarithm with base 10. The third parameter is the mean Dyson temperature of the extrasolar planet, for which I established four main temperature classes: F represents the Freezing class, W the Water class, G the Gaseous class, and R the Roasters class. I devised one additional class, however: P, the Pulsar class, which concerns extrasolar planets orbiting pulsar stars. The fourth parameter is eccentricity. If the attributes of the surface of the extrasolar planet are known, we are able to establish this additional parameter where t represents a terrestrial planet, g a gaseous planet, and i an ice planet. According to this taxonomy scale, for example, Earth is 1E0W0t, Neptune is 1N1.5F0i, and extrasolar planet 55 Cnc e is 9E-1.8R1.

  18. Spumaretroviruses: Updated taxonomy and nomenclature. (United States)

    Khan, Arifa S; Bodem, Jochen; Buseyne, Florence; Gessain, Antoine; Johnson, Welkin; Kuhn, Jens H; Kuzmak, Jacek; Lindemann, Dirk; Linial, Maxine L; Löchelt, Martin; Materniak-Kornas, Magdalena; Soares, Marcelo A; Switzer, William M


    Spumaretroviruses, commonly referred to as foamy viruses, are complex retroviruses belonging to the subfamily Spumaretrovirinae, family Retroviridae, which naturally infect a variety of animals including nonhuman primates (NHPs). Additionally, cross-species transmissions of simian foamy viruses (SFVs) to humans have occurred following exposure to tissues of infected NHPs. Recent research has led to the identification of previously unknown exogenous foamy viruses, and to the discovery of endogenous spumaretrovirus sequences in a variety of host genomes. Here, we describe an updated spumaretrovirus taxonomy that has been recently accepted by the International Committee on Taxonomy of Viruses (ICTV) Executive Committee, and describe a virus nomenclature that is generally consistent with that used for other retroviruses, such as lentiviruses and deltaretroviruses. This taxonomy can be applied to distinguish different, but closely related, primate (e.g., human, ape, simian) foamy viruses as well as those from other hosts. This proposal accounts for host-virus co-speciation and cross-species transmission. Published by Elsevier Inc.

  19. Solo-Surgeon Single-Port Laparoscopic Anterior Resection for Sigmoid Colon Cancer: Comparative Study. (United States)

    Choi, Byung Jo; Jeong, Won Jun; Kim, Say-June; Lee, Sang Chul


    To report our experience with solo-surgeon, single-port laparoscopic anterior resection (solo SPAR) for sigmoid colon cancer. Data from sigmoid colon cancer patients who underwent anterior resections (ARs) using the single-port, solo surgery technique (n = 31) or the conventional single-port laparoscopic technique (n = 45), between January 2011 and July 2016, were retrospectively analyzed. In the solo surgeries, making the transumbilical incision into the peritoneal cavity was facilitated through the use of a self-retaining retractor system. After establishing a single port through the umbilicus, an adjustable mechanical camera holder replaced the human scope assistant. Patient and tumor characteristics and operative, pathologic, and postoperative outcomes were compared. The operative times and estimated blood losses were similar for the patients in both treatment groups. In addition, most of the postoperative variables were comparable between the two groups, including postoperative complications and hospital stays. In the solo SPAR group, comparable lymph nodes were attained, and sufficient proximal and distal cut margins were obtained. The difference in the proximal cut margin significantly favored the solo SPAR, compared with the conventional AR group (P = .000). This study shows that solo SPAR, using a passive camera system, is safe and feasible for use in sigmoid colon cancer surgery, if performed by an experienced laparoscopic surgeon. In addition to reducing the need for a surgical assistant, the oncologic requirements, including adequate margins and sufficient lymph node harvesting, could be fulfilled. Further evaluations, including prospective randomized studies, are warranted.

  4. Generalized metamaterials: Definitions and taxonomy. (United States)

    Kim, Noori; Yoon, Yong-Jin; Allen, Jont B


    This article reviews the development of metamaterials (MM), starting from Newton's discovery of the wave equation, and ends with a discussion of the need for a technical taxonomy (classification) of these materials, along with a better defined definition of metamaterials. It is intended to be a technical definition of metamaterials, based on a historical perspective. The evolution of MMs began with the discovery of the wave equation, traceable back to Newton's calculation of the speed of sound. The theory of sound evolved to include quasi-statics (Helmholtz) and the circuit equations of Kirchhoff's circuit laws, leading to the ultimate development of Maxwell's equations and the equation for the speed of light. Be it light, or sound, the speed of the wave-front travel defines the wavelength, and thus the quasi-static (QS) approximation. But there is much more at stake than QSs. Taxonomy requires a proper statement of the laws of physics, which includes at least the six basic network postulates: (P1) causality (non-causal/acausal), (P2) linearity (non-linear), (P3) real (complex) time response, (P4) passive (active), (P5) time-invariant (time varying), and (P6) reciprocal (non-reciprocal). These six postulates are extended to include MMs.

  7. GEM Building Taxonomy (Version 2.0) (United States)

    Brzev, S.; Scawthorn, C.; Charleson, A.W.; Allen, L.; Greene, M.; Jaiswal, Kishor; Silva, V.


    This report documents the development and applications of the Building Taxonomy for the Global Earthquake Model (GEM). The purpose of the GEM Building Taxonomy is to describe and classify buildings in a uniform manner as a key step towards assessing their seismic risk, Criteria for development of the GEM Building Taxonomy were that the Taxonomy be relevant to seismic performance of different construction types; be comprehensive yet simple; be collapsible; adhere to principles that are familiar to the range of users; and ultimately be extensible to non-buildings and other hazards. The taxonomy was developed in conjunction with other GEM researchers and builds on the knowledge base from other taxonomies, including the EERI and IAEE World Housing Encyclopedia, PAGER-STR, and HAZUS. The taxonomy is organized as a series of expandable tables, which contain information pertaining to various building attributes. Each attribute describes a specific characteristic of an individual building or a class of buildings that could potentially affect their seismic performance. The following 13 attributes have been included in the GEM Building Taxonomy Version 2.0 (v2.0): 1.) direction, 2.)material of the lateral load-resisting system, 3.) lateral load-resisting system, 4.) height, 5.) date of construction of retrofit, 6.) occupancy, 7.) building position within a block, 8.) shape of the building plan, 9.) structural irregularity, 10.) exterior walls, 11.) roof, 12.) floor, 13.) foundation system. The report illustrates the pratical use of the GEM Building Taxonomy by discussing example case studies, in which the building-specific characteristics are mapped directly using GEM taxonomic attributes and the corresponding taxonomic string is constructed for that building, with "/" slash marks separating attributes. For example, for the building shown to the right, the GEM Taxonomy string is: DX1/MUR+CLBRS+MOCL2/LWAL3/

  9. Development of a consensus taxonomy of sedentary behaviors (SIT: report of Delphi Round 1.

    Directory of Open Access Journals (Sweden)

    Sebastien Francois Martin Chastin

    Full Text Available BACKGROUND: Over the last decade, sedentary behaviors have emerged as a distinctive behavioral paradigm with deleterious effects on health independent of physical activity. The next phase of research is to establish dose response between sedentary behaviors and health outcomes and improve understanding of context and determinants of these behaviors. Establishing a common taxonomy of these behaviors is a necessary step in this process. AIM: The Sedentary behavior International Taxonomy project was developed to establish a classification of sedentary behaviors by use of a formal consensus process. METHODS: The study follows a Delphi process in three Rounds. A preparatory stage informed the development of terms of reference documents. In Round 1, experts were asked to make statements about the taxonomy; 1 its purpose and use ; 2 the domains, categories or facets that should be consider and include; 3 the structure/architecture to arrange and link these domains and facets. In Round 2 experts will be presented with a draft taxonomy emerging from Round 1 and invited to comment and propose alterations. The taxonomy will then be finalised at the outset of this stage. RESULTS: Results of Round 1 are reported here. There is a general consensus that a taxonomy will help advances in research by facilitating systematic and standardised: 1 investigation and analysis; 2 reporting and communication; 3 data pooling, comparison and meta-analysis; 4 development of measurement tools; 4 data descriptions, leading to higher quality in data querying and facilitate discoveries. There is also a consensus that such a taxonomy should be flexible to accommodate diverse purposes of use, and future advances in the field and yet provide a cross-disciplinary common language. A consensual taxonomy structure emerged with nine primary facets (Purpose, Environment, Posture, Social, Measurement, Associated behavior, Status, Time, Type and the draft structure presented here for

  10. Scientific Teaching: Defining a Taxonomy of Observable Practices (United States)

    Couch, Brian A.; Brown, Tanya L.; Schelpat, Tyler J.; Graham, Mark J.; Knight, Jennifer K.


    Over the past several decades, numerous reports have been published advocating for changes to undergraduate science education. These national calls inspired the formation of the National Academies Summer Institutes on Undergraduate Education in Biology (SI), a group of regional workshops to help faculty members learn and implement interactive teaching methods. The SI curriculum promotes a pedagogical framework called Scientific Teaching (ST), which aims to bring the vitality of modern research into the classroom by engaging students in the scientific discovery process and using student data to inform the ongoing development of teaching methods. With the spread of ST, the need emerges to systematically define its components in order to establish a common description for education researchers and practitioners. We describe the development of a taxonomy detailing ST’s core elements and provide data from classroom observations and faculty surveys in support of its applicability within undergraduate science courses. The final taxonomy consists of 15 pedagogical goals and 37 supporting practices, specifying observable behaviors, artifacts, and features associated with ST. This taxonomy will support future educational efforts by providing a framework for researchers studying the processes and outcomes of ST-based course transformations as well as a concise guide for faculty members developing classes.

  11. Taxonomy of oxalotrophic Methylobacterium strains (United States)

    Sahin, Nurettin; Kato, Yuko; Yilmaz, Ferah


    Most of the oxalotrophic bacteria are facultative methylotrophs and play important ecological roles in soil fertility and cycling of elements. This study gives a detailed picture of the taxonomy and diversity of these bacteria and provides new information about the taxonomical variability within the genus Methylobacterium. Twelve mesophilic, pink-pigmented, and facultatively methylotrophic oxalate-oxidizing strains were included in this work that had been previously isolated from the soil and some plant tissues by the potassium oxalate enrichment method. The isolates were characterized using biochemical tests, cellular lipid profiles, spectral characteristics of carotenoid pigments, G+C content of the DNA, and 16S rDNA sequencing. The taxonomic similarities among the strains were analyzed using the simple matching ( S SM) and Jaccard ( S J) coefficients, and the UPGMA clustering algorithm. The phylogenetic position of the strains was inferred by the neighbor-joining method on the basis of the 16S rDNA sequences. All isolates were Gram-negative, facultatively methylotrophic, oxidase and catalase positive, and required no growth factors. Based on the results of numerical taxonomy, the strains formed four closely related clusters sharing ≥85% similarity. Analysis of the 16S rDNA sequences demonstrated that oxalotrophic, pink-pigmented, and facultatively methylotrophic strains could be identified as members of the genus Methylobacterium. Except for M. variabile and M. aquaticum, all of the Methylobacterium type strains tested had the ability of oxalate utilization. Our results indicate that the capability of oxalate utilization seems to be an uncommon trait and could be used as a valuable taxonomic criterion for differentiation of Methylobacterium species.

  12. The evolution of trypanosomatid taxonomy. (United States)

    Kaufer, Alexa; Ellis, John; Stark, Damien; Barratt, Joel


    Trypanosomatids are protozoan parasites of the class Kinetoplastida predominately restricted to invertebrate hosts (i.e. possess a monoxenous life-cycle). However, several genera are pathogenic to humans, animals and plants, and have an invertebrate vector that facilitates their transmission (i.e. possess a dixenous life-cycle). Phytomonas is one dixenous genus that includes several plant pathogens transmitted by phytophagous insects. Trypanosoma and Leishmania are dixenous genera that infect vertebrates, including humans, and are transmitted by hematophagous invertebrates. Traditionally, monoxenous trypanosomatids such as Leptomonas were distinguished from morphologically similar dixenous species based on their restriction to an invertebrate host. Nonetheless, this criterion is somewhat flawed as exemplified by Leptomonas seymouri which reportedly infects vertebrates opportunistically. Similarly, Novymonas and Zelonia are presumably monoxenous genera yet sit comfortably in the dixenous clade occupied by Leishmania. The isolation of Leishmania macropodum from a biting midge (Forcipomyia spp.) rather than a phlebotomine sand fly calls into question the exclusivity of the Leishmania-sand fly relationship, and its suitability for defining the Leishmania genus. It is now accepted that classic genus-defining characteristics based on parasite morphology and host range are insufficient to form the sole basis of trypanosomatid taxonomy as this has led to several instances of paraphyly. While improvements have been made, resolution of evolutionary relationships within the Trypanosomatidae is confounded by our incomplete knowledge of its true diversity. The known trypanosomatids probably represent a fraction of those that exist and isolation of new species will help resolve relationships in this group with greater accuracy. This review incites a dialogue on how our understanding of the relationships between certain trypanosomatids has shifted, and discusses new knowledge

    Lambe, Patrick


    Taxonomies are often thought to play a niche role within content-oriented knowledge management projects. They are thought to be 'nice to have' but not essential. In this ground-breaking book, Patrick Lambe shows how they play an integral role in helping organizations coordinate and communicate effectively. Through a series of case studies, he demonstrates the range of ways in which taxonomies can help organizations to leverage and articulate their knowledge. A step-by-step guide in the book to running a taxonomy project is full of practical advice for knowledge managers and business owners ali

    This study explored the response of 28, second year undergraduate students to an innovative approach to a five-day solo. Periods of solitude are more likely to lead to positive outcomes when they are freely chosen than when they are programmed as part of a course. The extent to which a programmed solo can be "freely chosen" by the…

  16. Unravelling the tangled taxonomies of health informatics

    David Barrett


    Full Text Available Even though informatics is a term used commonly in healthcare, it can be a confusing and disengaging one. Many definitions exist in the literature, and attempts have been made to develop a clear taxonomy. Despite this, informatics is still a term that lacks clarity in both its scope and the classification of sub-terms that it encompasses.This paper reviews the importance of an agreed taxonomy and explores the challenges of establishing exactly what is meant by health informatics (HI. It reviews what a taxonomy should do, summarises previous attempts at categorising and organising HI and suggests the elements to consider when seeking to develop a system of classification.The paper does not provide all the answers, but it does clarify the questions. By plotting a path towards a taxonomy of HI, it will be possible to enhance understanding and optimise the benefits of embracing technology in clinical practice.

    Hlava, Marjorie


    This book outlines the basic principles of creation and maintenance of taxonomies and thesauri. It also provides step by step instructions for building a taxonomy or thesaurus and discusses the various ways to get started on a taxonomy construction project.Often, the first step is to get management and budgetary approval, so I start this book with a discussion of reasons to embark on the taxonomy journey. From there I move on to a discussion of metadata and how taxonomies and metadata are related, and then consider how, where, and why taxonomies are used.Information architecture has its corner

  1. Characteristics of Female Solo and Female Co-Offenders and Male Solo Sexual Offenders Against Children. (United States)

    Williams, Rebecca; Gillespie, Steven M; Elliott, Ian A; Eldridge, Hilary J


    Studies have highlighted differences in the victim choice, offender, and offense characteristics of female and male sexual offenders. However, little is known about how solo and co-offending females differ from solo male sexual offenders. We compared the characteristics of 20 solo and 20 co-offending females (co-offended with a male and/or female accomplice), and 40 male sexual offenders against children. We found that solo female offenders showed the most evidence of personal problems, including depression and sexual dissatisfaction. Compared with male offenders, female co-offenders showed poorer self-management, but better sexual self-regulation. Male offenders had a greater history of offending and showed more evidence of sexual abuse supportive cognitions relative to both solo and co-offending females. These results are consistent with the need for a gender-specific approach to working with sexual offenders and may have implications for understanding the often complex treatment needs of these clients.

  2. Towards an Artificial Space Object Taxonomy (United States)

    Wilkins, M.; Schumacher, P.; Jah, M.; Pfeffer, A.


    Object recognition is the first step in positively identifying a resident space object (RSO), i.e. assigning an RSO to a category such as GPS satellite or space debris. Object identification is the process of deciding that two RSOs are in fact one and the same. Provided we have appropriately defined a satellite taxonomy that allows us to place a given RSO into a particular class of object without any ambiguity, one can assess the probability of assignment to a particular class by determining how well the object satisfies the unique criteria of belonging to that class. Ultimately, tree-based taxonomies delineate unique signatures by defining the minimum amount of information required to positively identify a RSO. Therefore, taxonomic trees can be used to depict hypotheses in a Bayesian object recognition and identification process. This work describes a new RSO taxonomy along with specific reasoning behind the choice of groupings. An alternative taxonomy was recently presented at the Sixth Conference on Space Debris in Darmstadt, Germany. [1] The best example of a taxonomy that enjoys almost universal scientific acceptance is the classical Linnaean biological taxonomy. A strength of Linnaean taxonomy is that it can be used to organize the different kinds of living organisms, simply and practically. Every species can be given a unique name. This uniqueness and stability are a result of the acceptance by biologists specializing in taxonomy, not merely of the binomial names themselves. Fundamentally, the taxonomy is governed by rules for the use of these names, and these are laid down in formal Nomenclature Codes. We seek to provide a similar formal nomenclature system for RSOs through a defined tree-based taxonomy structure. Each categorization, beginning with the most general or inclusive, at any level is called a taxon. Taxon names are defined by a type, which can be a specimen or a taxon of lower rank, and a diagnosis, a statement intended to supply characters that

  3. Forensic Taxonomy of Android Social Apps. (United States)

    Azfar, Abdullah; Choo, Kim-Kwang Raymond; Liu, Lin


    An Android social app taxonomy incorporating artifacts that are of forensic interest will enable users and forensic investigators to identify the personally identifiable information (PII) stored by the apps. In this study, 30 popular Android social apps were examined. Artifacts of forensic interest (e.g., contacts lists, chronology of messages, and timestamp of an added contact) were recovered. In addition, images were located, and Facebook token strings used to tie account identities and gain access to information entered into Facebook by a user were identified. Based on the findings, a two-dimensional taxonomy of the forensic artifacts of the social apps is proposed. A comparative summary of existing forensic taxonomies of different categories of Android apps, designed to facilitate timely collection and analysis of evidentiary materials from Android devices, is presented. © 2016 American Academy of Forensic Sciences.

  4. Scientific teaching: defining a taxonomy of observable practices. (United States)

    Couch, Brian A; Brown, Tanya L; Schelpat, Tyler J; Graham, Mark J; Knight, Jennifer K


    Over the past several decades, numerous reports have been published advocating for changes to undergraduate science education. These national calls inspired the formation of the National Academies Summer Institutes on Undergraduate Education in Biology (SI), a group of regional workshops to help faculty members learn and implement interactive teaching methods. The SI curriculum promotes a pedagogical framework called Scientific Teaching (ST), which aims to bring the vitality of modern research into the classroom by engaging students in the scientific discovery process and using student data to inform the ongoing development of teaching methods. With the spread of ST, the need emerges to systematically define its components in order to establish a common description for education researchers and practitioners. We describe the development of a taxonomy detailing ST's core elements and provide data from classroom observations and faculty surveys in support of its applicability within undergraduate science courses. The final taxonomy consists of 15 pedagogical goals and 37 supporting practices, specifying observable behaviors, artifacts, and features associated with ST. This taxonomy will support future educational efforts by providing a framework for researchers studying the processes and outcomes of ST-based course transformations as well as a concise guide for faculty members developing classes. © 2015 B.

  5. Defending the solo and small practice neurologist. (United States)

    Jones, Elaine C; Evans, David A


    Changes in health care are having a dramatic effect on the practice of medicine. In 2005, a National Center for Health Statistics survey showed that 55%-70% of physicians are in small/solo practices. These data also demonstrated that 70% of physicians identified themselves as owners. Since passage of the Affordable Care Act (ACA) in 2010, neurologists report an 8% increase in academic practice settings, a 2% decrease in private practice settings, and a 5% decrease in solo practice settings. Surveys of family physicians showed that 60% are now employees of hospitals or larger groups. A survey by The Physicians Foundation showed that 89% of physicians believed that the traditional model of independent private practice is either "on shaky ground" or "a dinosaur soon to go extinct." With the changes expected from the ACA, solo/small practices will continue to face challenges and therefore must pay close attention to business and clinical metrics.

  6. A taxonomy for disease management: a scientific statement from the American Heart Association Disease Management Taxonomy Writing Group. (United States)

    Krumholz, Harlan M; Currie, Peter M; Riegel, Barbara; Phillips, Christopher O; Peterson, Eric D; Smith, Renee; Yancy, Clyde W; Faxon, David P


    Disease management has shown great promise as a means of reorganizing chronic care and optimizing patient outcomes. Nevertheless, disease management programs are widely heterogeneous and lack a shared definition of disease management, which limits our ability to compare and evaluate different programs. To address this problem, the American Heart Association's Disease Management Taxonomy Writing Group developed a system of classification that can be used both to categorize and compare disease management programs and to inform efforts to identify specific factors associated with effectiveness. The AHA Writing Group began with a conceptual model of disease management and its components and subsequently validated this model over a wide range of disease management programs. A systematic MEDLINE search was performed on the terms heart failure, diabetes, and depression, together with disease management, case management, and care management. The search encompassed articles published in English between 1987 and 2005. We then selected studies that incorporated (1) interventions designed to improve outcomes and/or reduce medical resource utilization in patients with heart failure, diabetes, or depression and (2) clearly defined protocols with at least 2 prespecified components traditionally associated with disease management. We analyzed the study protocols and used qualitative research methods to develop a disease management taxonomy with our conceptual model as the organizing framework. The final taxonomy includes the following 8 domains: (1) Patient population is characterized by risk status, demographic profile, and level of comorbidity. (2) Intervention recipient describes the primary targets of disease management intervention and includes patients and caregivers, physicians and allied healthcare providers, and healthcare delivery systems. (3) Intervention content delineates individual components, such as patient education, medication management, peer support, or some

    Full Text Available The purpose of this study is to explore the transformation of city form and its structure in Solo which has developed from time to time. The method of this research was carried out by a-three-archive research strategy as follows: primary files; secondary files and physical files. The primary files referred to the old Javanese documentary (examples: parintah, undhang-undhang, pranatan, piyagem, kakancingan, serat, gugat, penget, babad. The secondary files referred to the document of local, national and international historians (examples: Ricklefs, Lombard, Vorstensteden, Muljana, Notosusanto, Kartodirdjo, Sajid and Javanese architecture researchers (Ronald, Ikaputra, Adishakti. While the physical files referred to the field research that was conducted by interviews and collecting the artefacts. The main findings of study of morphology in the city of Solo were: the 'skeleton' element grew in three formations (central, cluster and organic; the 'meat' element grew in three formations also (horizontal, vertical, and interstitial; and the 'blood' element increased from the native people (Javanese, Madura, Banjar to foreign people (Chinese, Arab, India, Dutch and changed from agricultural to non-agricultural activities. The other findings were the city of Solo was constructed by a-three-concept of urban design as follows: the organic concept which was conducted by native people; the colony concept which was conducted by the Dutch; and the cosmology concept which was conducted by the Javanese Kingdom. In 1500s-1750s, initially the city of Solo was a settlement grew at the bank of Bengawan Solo. Afterwards, in 1750s-1850s it developed into a combined water- and land- based urban fabric Since 1850s, the city of Solo has left the river transportation and changed into the land transportation.

  15. Freedom Solo Versus Trifecta Bioprotheses: Clinical and Hemodynamic Evaluation after Propensity Score Matching. (United States)

    J Cerqueira, Rui; Melo, Renata; Moreira, Soraia; A Saraiva, Francisca; Andrade, Marta; Salgueiro, Elson; Almeida, Jorge; J Amorim, Mário; Pinho, Paulo; Lourenço, André; F Leite-Moreira, Adelino


    To compare stentless Freedom Solo and stented Trifecta aortic bioprostheses regarding hemodynamic profile, left ventricular mass regression, early and late postoperative outcomes and survival. Longitudinal cohort study of consecutive patients undergoing aortic valve replacement (from 2009 to 2016) with either Freedom Solo or Trifecta at one centre. Local databases and national records were queried. Postoperative echocardiography (3-6 months) was obtained for hemodynamic profile (mean transprosthetic gradient and effective orifice area) and left ventricle mass determination. After propensity score matching (21 covariates), Kaplan-Meier analysis and cumulative incidence analysis were performed for survival and combined outcome of structural valve deterioration and endocarditis, respectively. Hemodynamics and left ventricle mass regression were assessed by a mixed- -effects model including propensity score as a covariate. From a total sample of 397 Freedom Solo and 525 Trifecta patients with a median follow-up time of 4.0 (2.2- 6.0) and 2.4 (1.4-3.7) years, respectively, a matched sample of 329 pairs was obtained. Well-balanced matched groups showed no difference in survival (hazard ratio=1.04, 95% confidence interval=0.69-1.56) or cumulative hazards of combined outcome (subhazard ratio=0.54, 95% confidence interval=0.21-1.39). Although Trifecta showed improved hemodynamic profile compared to Freedom Solo, no differences were found in left ventricle mass regression. Trifecta has a slightly improved hemodynamic profile compared to Freedom Solo but this does not translate into differences in the extent of mass regression, postoperative outcomes or survival, which were good and comparable for both bioprostheses. Long-term follow-up is needed for comparisons with older models of bioprostheses.

  16. Taxonomy for Common-Cause Failure Vulnerability and Mitigation

    Energy Technology Data Exchange (ETDEWEB)

    Wood, Richard Thomas [Oak Ridge National Lab. (ORNL), Oak Ridge, TN (United States); Korsah, Kofi [Oak Ridge National Lab. (ORNL), Oak Ridge, TN (United States); Mullens, James Allen [Oak Ridge National Lab. (ORNL), Oak Ridge, TN (United States); Pullum, Laura L. [Oak Ridge National Lab. (ORNL), Oak Ridge, TN (United States)


    Applying current guidance and practices for common-cause failure (CCF) mitigation to digital instrumentation and control (I&C) systems has proven problematic, and the regulatory environment has been unpredictable. The potential for CCF vulnerability inhibits I&C modernization, thereby challenging the long-term sustainability of existing plants. For new plants and advanced reactor concepts, concern about CCF vulnerability in highly integrated digital I&C systems imposes a design burden that results in higher costs and increased complexity. The regulatory uncertainty in determining which mitigation strategies will be acceptable (e.g., what diversity is needed and how much is sufficient) drives designers to adopt complicated, costly solutions devised for existing plants. To address the conditions that constrain the transition to digital I&C technology by the US nuclear industry, crosscutting research is needed to resolve uncertainty, demonstrate necessary characteristics, and establish an objective basis for qualification of digital technology for nuclear power plant (NPP) I&C applications. To fulfill this research need, Oak Ridge National Laboratory is investigating mitigation of CCF vulnerability for nuclear-qualified applications. The outcome of this research is expected to contribute to a fundamentally sound, comprehensive basis to qualify digital technology for nuclear power applications. This report documents the development of a CCF taxonomy. The basis for the CCF taxonomy was generated by determining consistent terminology and establishing a classification approach. The terminology is based on definitions from standards, guides, and relevant nuclear power industry technical reports. The classification approach is derived from identified classification schemes focused on I&C systems and key characteristics, including failure modes. The CCF taxonomy provides the basis for a systematic organization of key systems aspects relevant to analyzing the potential for

  17. Classification and taxonomy of vegetable macergens

    Directory of Open Access Journals (Sweden)

    Bukola Rhoda Aremu


    Full Text Available Macergens are bacteria capable of releasing pectic enzymes (pectolytic bacteria. These enzymatic actions result in the separation of plant tissues leading to total plant destruction. This can be attributed to soft rot diseases in vegetables. These macergens primarily belong to the genus Erwinia and to a range of opportunistic pathogens namely: the Xanthomonas spp, Pseudomonas spp., Clostridium spp., Cytophaga spp. and Bacillus spp. They consist of taxa that displayed considerable heterogeneity and intermingled with members of other genera belonging to the Enterobacteriaceae. They have been classified based on phenotypic, chemotaxonomic and genotypic which obviously not necessary in the taxonomy of all bacterial genera for defining bacterial species and describing new ones These taxonomic markers have been used traditionally as a simple technique for identification of bacterial isolates. The most important fields of taxonomy are supposed to be based on clear, reliable and worldwide applicable criteria. Hence, this review clarifies the taxonomy of the macergens to the species level and revealed that their taxonomy is beyond complete. For discovery of additional species, further research with the use modern molecular methods like phylogenomics need to be done. This can precisely define classification of macergens resulting in occasional, but significant changes in previous taxonomic schemes of these macergens.

  1. An Android Communication App Forensic Taxonomy. (United States)

    Azfar, Abdullah; Choo, Kim-Kwang Raymond; Liu, Lin


    Due to the popularity of Android devices and applications (apps), Android forensics is one of the most studied topics within mobile forensics. Communication apps, such as instant messaging and Voice over IP (VoIP), are one popular app category used by mobile device users, including criminals. Therefore, a taxonomy outlining artifacts of forensic interest involving the use of Android communication apps will facilitate the timely collection and analysis of evidentiary materials from such apps. In this paper, 30 popular Android communication apps were examined, where a logical extraction of the Android phone images was collected using XRY, a widely used mobile forensic tool. Various information of forensic interest, such as contact lists and chronology of messages, was recovered. Based on the findings, a two-dimensional taxonomy of the forensic artifacts of the communication apps is proposed, with the app categories in one dimension and the classes of artifacts in the other dimension. Finally, the artifacts identified in the study of the 30 communication apps are summarized using the taxonomy. It is expected that the proposed taxonomy and the forensic findings in this paper will assist forensic investigations involving Android communication apps. © 2016 American Academy of Forensic Sciences.

  3. Solo-Surgeon Retroauricular Approach Endoscopic Thyroidectomy. (United States)

    Lee, Doh Young; Baek, Seung-Kuk; Jung, Kwang-Yoon


    This study aimed to evaluate the feasibility and efficacy of solo-surgeon retroauricular thyroidectomy. For solo-surgery, we used an Endoeye Flex Laparo-Thoraco Videoscope (Olympus America, Inc.). A Vitom Karl Storz holding system (Karl Storz GmbH & Co.) composed of several bars connected by a ball-joint system was used for fixation of endoscope. A snake retractor and a brain-spoon retractor were used on the sternocleidomastoid. Endoscopic thyroidectomy using the solo-surgeon technique was performed in 10 patients having papillary thyroid carcinoma. The mean patient age was 36.0 ± 11.1 years, and all patients were female. There were no postoperative complications such as vocal cord paralysis and hematoma. When compared with the operating times and volume of drainage of a control group of 100 patients who underwent surgery through the conventional retroauricular approach between May 2013 and December 2015, the operating times and volume of drainage were not significantly different (P = .781 and .541, respectively). Solo-surgeon retroauricular thyroidectomy is safe and feasible when performed by a surgeon competent in endoscopic thyroidectomy.

  5. Diagnosis - the limiting focus of taxonomy. (United States)

    Sturmberg, Joachim P; Martin, Carmel M


    The focus on the diagnosis is a pivotal aspect of medical practice since antiquity. Diagnostic taxonomy helped to categorize ailments to improve medical care, and in its social sense resulted in validation of the sick role for some, but marginalization or stigmatization for others. In the medical industrial complex, diagnostic taxonomy structured health care financing, management and practitioner remuneration. However, with increasing demands from multiple agencies, there are increasing unintended and unwarranted consequences of our current taxonomies and diagnostic processes resulting from the conglomeration of underpinning concepts, theories, information and motivations. We argue that the increasing focus on the diagnosis resulted in excessive compartmentalization - 'partialism' - of medical practice, diminishing medical care and being naively simplistic in light of the emerging understanding of the interconnected nature of the diseasome. The human is a complex organic system of interconnecting dynamics and feedback loops responding to internal and external forces including genetic, epigenetic and environmental attractors, rather than the sum of multiple discrete organs which can develop isolated diseases or multiple morbidities. Solutions to these unintended consequences of many contemporary health system processes involve revisiting the nature of diagnostic taxonomies and the processes of their construction. A dynamic taxonomic framework would shift to more relevant attractors at personal, clinical and health system levels recognizing the non-linear nature of health and disease. Human health at an individual, group and population level is the ability to adapt to internal and external stressors with resilience throughout the life course, yet diagnostic taxonomies are increasingly constructed around fixed anchors. Understanding diagnosis as dissecting, pigeonholing or bean counting (learning by dividing) is no longer useful, the challenge for the future is to

  9. Toward a comprehensive taxonomy of human motives (United States)

    Talevich, Jennifer R.; Walsh, David A.; Iyer, Ravi; Chopra, Gurveen


    A major success in personality has been the development of a consensual structure of traits. However, much less progress has been made on the structure of an equally important aspect of human psychology: motives. We present an empirically and theoretically structured hierarchical taxonomy of 161 motives gleaned from a literature review from McDougall to the present and based on the cluster analysis of similarity judgments among these 161 motives, a broader sampling of motives than previous work. At the broadest level were: Meaning, Communion, and Agency. These divided into nine clusters: Morality & Virtue, Religion & Spirituality, Self-Actualization, Avoidance, Social Relating, Family, Health, Mastery & Competence, and Financial & Occupational Success. Each divided into more concrete clusters to form 5 levels. We discuss contributions to research on motives, especially recent work on goal systems, and the aiding of communication and systematization of research. Finally, we compare the taxonomy to other motive organizations. PMID:28231252

    Despite the increasing importance of digitization for economy and society, there is few structuring of the very heterogenous kinds of digital work. Representatives from business, politics and science need a basis for the development of strategies to encounter the challenges that result from this digitization. We aim at delivering a contribution to that basis by systematically investigating what different types of digital work exist and by developing a taxonomy. As a first important step towar...

  11. An Empirical Taxonomy of Crowdfunding Intermediaries


    Haas, Philipp; Blohm, Ivo; Leimeister, Jan Marco


    Due to the recent popularity of crowdfunding, a broad magnitude of crowdfunding intermediaries has emerged, while research on crowdfunding intermediaries has been largely neglected. As a consequence, existing classifications of crowdfunding intermediaries are conceptual, lack theoretical grounding, and are not empirically validated. Thus, we develop an empirical taxonomy of crowdfunding intermediaries, which is grounded in the theories of two-sided markets and financial intermediation. Integr...

    David Peón; Manel Antelo; Anxo Calvo-Silvosa


    This paper overviews the theoretical and empirical research on behavioral biases and their influence in the literature. To provide a systematic exposition, we present a unified framework that takes the reader through an original taxonomy, based on the reviews of relevant authors in the field. In particular, we establish three broad categories that may be distinguished: heuristics and biases; choices, values and frames; and social factors. We then describe the main biases within each category,...

  13. A taxonomy for human reliability analysis

    International Nuclear Information System (INIS)

    Beattie, J.D.; Iwasa-Madge, K.M.


    A human interaction taxonomy (classification scheme) was developed to facilitate human reliability analysis in a probabilistic safety evaluation of a nuclear power plant, being performed at Ontario Hydro. A human interaction occurs, by definition, when operators or maintainers manipulate, or respond to indication from, a plant component or system. The taxonomy aids the fault tree analyst by acting as a heuristic device. It helps define the range and type of human errors to be identified in the construction of fault trees, while keeping the identification by different analysts consistent. It decreases the workload associated with preliminary quantification of the large number of identified interactions by including a category called 'simple interactions'. Fault tree analysts quantify these according to a procedure developed by a team of human reliability specialists. The interactions which do not fit into this category are called 'complex' and are quantified by the human reliability team. The taxonomy is currently being used in fault tree construction in a probabilistic safety evaluation. As far as can be determined at this early stage, the potential benefits of consistency and completeness in identifying human interactions and streamlining the initial quantification are being realized

  14. Overview of the taxonomy of zooxanthellate Scleractinia. (United States)

    Veron, John


    Coral taxonomy has entered a historical phase where nomenclatorial uncertainty is rapidly increasing. The fundamental cause is mandatory adherence to historical monographs that lack essential information of all sorts, and also to type specimens, if they exist at all, that are commonly unrecognizable fragments or are uncharacteristic of the species they are believed to represent. Historical problems, including incorrect subsequent type species designations, also create uncertainty for many well-established genera. The advent of in situ studies in the 1970s revealed these issues; now molecular technology is again changing the taxonomic landscape. The competing methodologies involved must be seen in context if they are to avoid becoming an additional basis for continuing nomenclatorial instability. To prevent this happening, the International Commission on Zoological Nomenclature (ICZN) will need to focus on rules that consolidate well-established nomenclature and allow for the designation of new type specimens that are unambiguous, and which include both skeletal material and soft tissue for molecular study. Taxonomic and biogeographic findings have now become linked, with molecular methodologies providing the capacity to re-visit past taxonomic decisions, and to extend both taxonomy and biogeography into the realm of evolutionary theory. It is proposed that most species will ultimately be seen as operational taxonomic units that are human rather than natural constructs, which in consequence will always have fuzzy morphological, genetic, and distribution boundaries. The pathway ahead calls for the integration of morphological and molecular taxonomies, and for website delivery of information that crosses current discipline boundaries.

  16. Mathematics, curriculum and assessment: The role of taxonomies in the quest for coherence

    Directory of Open Access Journals (Sweden)

    Caroline Long


    Full Text Available A challenge encountered when monitoring mathematics teaching and learning at high school is that taxonomies such as Bloom’s, and variations of this work, are not entirely adequate for providing meaningful feedback to teachers beyond very general cognitive categories that are difficult to interpret. Challenges of this nature are also encountered in the setting of examinations, where the requirement is to cover a range of skills and cognitive domains. The contestation as to the cognitive level is inevitable as it is necessary to analyse the relationship between the problem and the learners’ background experience. The challenge in the project described in this article was to find descriptive terms that would be meaningful to teachers. The first attempt at providing explicit feedback was to apply the assessment frameworks that include a content component and a cognitive component, namely knowledge, routine procedures, complex procedures and problem solving, currently used in the South African curriculum documents. The second attempt investigated various taxonomies, including those used in international assessments and in mathematics education research, for constructs that teachers of mathematics might find meaningful. The final outcome of this investigation was to apply the dimensions required to understand a mathematical concept proposed by Usiskin (2012: the skills-algorithm, property-proof, use-application and representation-metaphor dimension. A feature of these dimensions is that they are not hierarchical; rather, within each of the dimensions, the mathematical task may demand recall but may also demand the highest level of creativity. For our purpose, we developed a two-way matrix using Usiskin’s dimensions on one axis and a variation of Bloom’s revised taxonomy on the second axis. Our findings are that this two-way matrix provides an alternative to current taxonomies, is more directly applicable to mathematics and provides the

  18. A Rain Taxonomy for Degraded Visual Environment Mitigation (United States)

    Gatlin, P. N.; Petersen, W. A.


    This Technical Memorandum (TM) provides a description of a rainfall taxonomy that defines the detailed characteristics of naturally occurring rainfall. The taxonomy is based on raindrop size measurements collected around the globe and encompasses several different climate types. Included in this TM is a description of these rainfall observations, an explanation of methods used to process those data, and resultant metrics comprising the rain taxonomy database. Each of the categories in the rain taxonomy are characterized by a unique set of raindrop sizes that can be used in simulations of electromagnetic wave propagation through a rain medium.

  19. A literature review on the levels of automation during the years. What are the different taxonomies that have been proposed? (United States)

    Vagia, Marialena; Transeth, Aksel A; Fjerdingen, Sigurd A


    In this paper we present a literature review of the evolution of the levels of autonomy from the end of the 1950s up until now. The motivation of this study was primarily to gather and to compare the literature that exists, on taxonomies on levels of automation. Technical developments within both computer hardware and software have made it possible to introduce autonomy into virtually all aspects of human-machine systems. The current study, is focusing on how different authors treat the problem of different levels of automation. The outcome of this study is to present the differences between the proposed levels of automation and the various taxonomies, giving the potential users a number of choices in order to decide which taxonomy satisfies their needs better. In addition, this paper surveys deals with the term adaptive automation, which seems to be a new trend in the literature on autonomy. Copyright © 2015 Elsevier Ltd and The Ergonomics Society.

  2. "Ring" in the solo child singing voice. (United States)

    Howard, David M; Williams, Jenevora; Herbst, Christian T


    Listeners often describe the voices of solo child singers as being "pure" or "clear"; these terms would suggest that the voice is not only pleasant but also clearly audible. The audibility or clarity could be attributed to the presence of high-frequency partials in the sound: a "brightness" or "ring." This article aims to investigate spectrally the acoustic nature of this ring phenomenon in children's solo voices, and in particular, relating it to their "nonring" production. Additionally, this is set in the context of establishing to what extent, if any, the spectral characteristics of ring are shared with those of the singer's formant cluster associated with professional adult opera singers in the 2.5-3.5kHz region. A group of child solo singers, acknowledged as outstanding by a singing teacher who specializes in teaching professional child singers, were recorded in a major UK concert hall performing Come unto him, all ye that labour, from the aria He shall feed his flock from The Messiah by GF Handel. Their singing was accompanied by a recording of a piano played through in-ear headphones. Sound pressure recordings were made from well within the critical distance in the hall. The singers were observed to produce notes with and without ring, and these recordings were analyzed in the frequency domain to investigate their spectra. The results indicate that there is evidence to suggest that ring in child solo singers is carried in two areas of the output spectrum: first in the singer's formant cluster region, centered around 4kHz, which is more than 1000Hz higher than what is observed in adults; and second in the region around 7.5-11kHz where a significant strengthening of harmonic presence is observed. A perceptual test has been carried out demonstrating that 94% of 62 listeners label a synthesized version of the calculated overall average ring spectrum for all subjects as having ring when compared with a synthesized version of the calculated overall average nonring

  3. Taxonomy of the nuclear plant operator's role

    International Nuclear Information System (INIS)

    Kisner, R.A.; Fullerton, A.M.; Frey, P.R.; Dougherty, E.M.


    A program is presently under way at the Oak Ridge National Laboratory (ORNL) to define the functional design requirements of operational aids for nuclear power plant operators. A first and important step in defining these requirements is to develop an understanding of the operator's role or function. This paper describes a taxonomy of operator functions that applies during all operational modes and conditions of the plant. Other topics such as the influence of automation, role acceptance, and the operator's role during emergencies are also discussed. This systematic approach has revealed several areas which have potential for improving the operator's ability to perform his role

  5. Starting SOLO: A multi-pronged scaffolding approach for developing critical climate literacies (United States)

    Hartman, K.; Goodkin, N.


    As part of Nanyang Technological University's general education requirement, all science and math students must complete a multidisciplinary environmental sustainability course during the spring term. In addition to foundational earth sciences material, the course of 600 students heavily emphasizes the development of multidisciplinary problem solving and communication strategies. Assessments conducted with previous iterations of the course found students had greater facility recalling facts and summarizing the course materials than they did evaluating climate change arguments, critically reasoning through sustainability issues, or thinking scientifically. To address this shortfall, we introduced the use of a rubric for peer review as one would treat acquiring expertise with any scientific tool—provide learners multiple opportunities for use in different contexts while providing interpretable and actionable feedback. In the most recent version of the course, we introduced a common rubric based on Biggs' (2014) SOLO taxonomy. We used the taxonomy to place the components of student learning along continuums signifying increasing levels of complexity. Our particular rubric highlighted five areas of importance when evaluating any written argument: clarity, argument structure, contextualization, use of evidence, and evidence sourcing. More important than the rubric itself was the iterative cycle of rubric use and expert feedback students received. For eight weeks, students used the rubric to evaluate articles on sustainability and were given feedback about how well their evaluations agreed with an "expert panel." As the semester progressed, the level of agreement between the students and the panel improved. Students used the rubric as a base for evaluating their peers' work at the end of the semester. We coded how constructive the comments students gave each other were and analyzed the weekly reading evaluations. Students whose evaluations aligned with the panel during

  9. Planetary Taxonomy: Label Round Bodies "Worlds" (United States)

    Margot, Jean-Luc; Levison, H. F.


    The classification of planetary bodies is as important to Astronomy as taxonomy is to other sciences. The etymological, historical, and IAU definitions of planet rely on a dynamical criterion, but some authors prefer a geophysical criterion based on "roundness". Although the former criterion is superior when it comes to classifying newly discovered objects, the conflict need not exist if we agree to identify the subset of "round" planetary objects as "worlds". This addition to the taxonomy would conveniently recognize that "round" objects such as Earth, Europa, Titan, Triton, and Pluto share some common planetary-type processes regardless of their distance from the host star. Some of these worlds are planets, others are not. Defining how round is round and handling the inevitable transition objects are non-trivial tasks. Because images at sufficient resolution are not available for the overwhelming majority of newly discovered objects, the degree of roundness is not a directly observable property and is inherently problematic as a basis for classification. We can tolerate some uncertainty in establishing the "world" status of a newly discovered object, and still establish its planet or satellite status with existing dynamical criteria. Because orbital parameters are directly observable, and because mass can often be measured either from orbital perturbations or from the presence of companions, the dynamics provide a robust and practical planet classification scheme. It may also be possible to determine which bodies are dynamically dominant from observations of the population magnitude/size distribution.

  13. The analysis of probability task completion; Taxonomy of probabilistic thinking-based across gender in elementary school students (United States)

    Sari, Dwi Ivayana; Budayasa, I. Ketut; Juniati, Dwi


    Formulation of mathematical learning goals now is not only oriented on cognitive product, but also leads to cognitive process, which is probabilistic thinking. Probabilistic thinking is needed by students to make a decision. Elementary school students are required to develop probabilistic thinking as foundation to learn probability at higher level. A framework of probabilistic thinking of students had been developed by using SOLO taxonomy, which consists of prestructural probabilistic thinking, unistructural probabilistic thinking, multistructural probabilistic thinking and relational probabilistic thinking. This study aimed to analyze of probability task completion based on taxonomy of probabilistic thinking. The subjects were two students of fifth grade; boy and girl. Subjects were selected by giving test of mathematical ability and then based on high math ability. Subjects were given probability tasks consisting of sample space, probability of an event and probability comparison. The data analysis consisted of categorization, reduction, interpretation and conclusion. Credibility of data used time triangulation. The results was level of boy's probabilistic thinking in completing probability tasks indicated multistructural probabilistic thinking, while level of girl's probabilistic thinking in completing probability tasks indicated unistructural probabilistic thinking. The results indicated that level of boy's probabilistic thinking was higher than level of girl's probabilistic thinking. The results could contribute to curriculum developer in developing probability learning goals for elementary school students. Indeed, teachers could teach probability with regarding gender difference.

  14. City image towards tourist attraction (case in Solo, Central Java) examining city image of solo as tourist attraction (United States)

    Wiyana, T.; Putranto, T. S.; Zulkarnain, A.; Kusdiana, R. N.


    Affective and cognitive image are two main factors that influence destination in Solo. The purpose of this research is to examine the two main factors of Solo towards tourist attraction. The research method is quantitative. Data collected from observation and survey. A total of 113 respondents obtained from accidental sampling method. The results indicate based on cognitive and affective image. Cognitive consists of culture, batik, city tagline, and community. While, affective consists of tradition, culinary, purposes, climate, and welcoming. The findings show that image has weak correlation towards tourist attraction of Solo. It means most of the tourists are not influenced by city image when they choose Solo as one of their travel destination. The differences between primary and minor image are also examined. Research implication is directed for local government to pursue continuous improvement particularly for the branding of Solo.

  15. Increasing educational attainment and mortality reduction: a systematic review and taxonomy. (United States)

    Byhoff, Elena; Hamati, Mary C; Power, Robyn; Burgard, Sarah A; Chopra, Vineet


    Understanding the relationship between increasing educational attainment and mortality reduction has important policy and public health implications. This systematic review of the literature establishes a taxonomy to facilitate evaluation of the association between educational attainment and early mortality. Following PRISMA guidelines, we searched Ovid Medline, Embase, PubMed and hand searches of references for English-language primary data analyses using education as an independent variable and mortality as a dependent variable. Initial searches were undertaken in February 2015 and updated in April 2016. One thousand, seven hundred and eleven unique articles were identified, 418 manuscripts were screened and 262 eligible studies were included in the review. After an iterative review process, the literature was divided into four study domains: (1) all-cause mortality (n = 68, 26.0%), (2) outcome-specific mortality (n = 89, 34.0%), (3) explanatory pathways (n = 51, 19.5%), and (4) trends over time (n = 54, 20.6%). These four domains comprise a novel taxonomy that can be implemented to better quantify the relationship between education and mortality. We propose an organizational taxonomy for the education-mortality literature based upon study characteristics that will allow for a more in-depth understanding of this association. Our review suggests that studies that include mediators or subgroups can explain part, but not all, of the relationship between education and early mortality.

  16. Social Media Use in Chronic Disease: A Systematic Review and Novel Taxonomy. (United States)

    Patel, Rajesh; Chang, Tammy; Greysen, S Ryan; Chopra, Vineet


    The purpose of this study is to evaluate clinical outcomes from applications of contemporary social media in chronic disease; to develop a conceptual taxonomy to categorize, summarize, and then analyze the current evidence base; and to suggest a framework for future studies on this topic. We performed a systematic review of MEDLINE via PubMed (January 2000 to January 2015) of studies reporting clinical outcomes on leading contemporary social media (ie, Facebook, Twitter, Wikipedia, YouTube) use in 10 chronic diseases. Two reviewers independently performed data extraction and quality assessment; characterization of study outcomes as positive, negative, neutral, or undefined impact; and inductive, thematic analysis to develop our taxonomy. Of 378 citations identified, 42 studies examining the use of Facebook (n = 16), blogs (n = 13), Twitter (n = 8), wikis (n = 5), and YouTube (n = 4) on outcomes in cancer (n = 14), depression (n = 13), obesity (n = 9), diabetes (n = 4), heart disease (n = 3), stroke (n = 2), and chronic lower respiratory tract infection (n = 1) were included. Studies were classified as support (n = 16), patient education (n = 10), disease modification (n = 6), disease management (n = 5), and diagnosis (n = 5) within our taxonomy. The overall impact of social media on chronic disease was variable, with 48% of studies indicating benefit, 45% neutral or undefined, and 7% suggesting harm. Among studies that showed benefit, 85% used either Facebook or blogs, and 40% were based within the domain of support. Using social media to provide social, emotional, or experiential support in chronic disease, especially with Facebook and blogs, appears most likely to improve patient care.

  18. Development of a taxonomy of behaviour change techniques used in individual behavioural support for smoking cessation. (United States)

    Michie, Susan; Hyder, Natasha; Walia, Asha; West, Robert


    Individual behavioural support for smoking cessation is effective but little is known about the 'active ingredients'. As a first step to establishing this, it is essential to have a consistent terminology for specifying intervention content. This study aimed to develop for the first time a reliable taxonomy of behaviour change techniques (BCTs) used within individual behavioural support for smoking cessation. Two source documents describing recommended practice were identified and analysed by two coders into component BCTs. The resulting taxonomy of BCTs was applied to 43 treatment manuals obtained from the English Stop Smoking Services (SSSs). In the first 28 of these, pairs of coders applied the taxonomy independently and inter-coder reliability was assessed. The BCTs were also categorised by two coders according to their main function and inter-coder reliability for this was assessed. Forty-three BCTs were identified which could be classified into four functions: 1) directly addressing motivation e.g. providing rewards contingent on abstinence, 2) maximising self-regulatory capacity or skills e.g. facilitating barrier identification and problem solving, 3) promoting adjuvant activities e.g. advising on stop-smoking medication, and 4) supporting other BCTs e.g. building general rapport. Percentage agreement in identifying BCTs and of categorising BCTs into their functions ranged from 86% to 95% and discrepancies were readily resolved through discussion. It is possible to develop a reliable taxonomy of BCTs used in behavioural support for smoking cessation which can provide a starting point for investigating the association between intervention content and outcome and can form a basis for determining competences required to undertake the role of stop smoking specialist.

  19. [Parameters of phoniatric examination of solo vocalists]. (United States)

    Mitrović, Slobodan; Jović, Rajko; Aleksić, Vesna; Cvejić, Biserka


    A phoniatrist analyzes the professional's voice at the beginning of his vocal studies or career but also later, in cases of voice disorder. Phoniatric examination of professional singers must be done according to "all inclusive" protocols of examination. Such protocols must establish the status of basic elements of phonatory system: activator, generator and resonator of voice and articulatory space. All patients requiring phoniatric examination no matter if they are candidates for professional singers, need to provide anamnestic data about their previous problems regarding voice or singing. This examination is necessary and it must include: examination of nose, cavum oris, pharynx, ears and larynx. This analysis is based on evaluation of physiological and pathophysiological manifestations of voice. Determination of musical voice range during phoniatric examination does not intend to make any classification of voice, nor to suggest to vocal teacher what he should count upon from future singers. Musical range can be determined only by a phoniatrist skilled in music or with musical training, but first of all vocal teacher. These methods are used for examination of phonatory function, or laryngeal pathology. They are not invasive and give objective and quantitative information. They include: laryngostroboscopy, spectral analysis of voice (sonography) and fundamental parameters of voice signal (computer program). Articulation is very important for solo singers, because good articulation contributes to qualitative emission of sound and expression of emotions. Tonal-threshold audiometry is performed as a hearing test. They include rhinomanometry, vital capacity measurements, maximal phonation time and phonation quotient. Phoniatric examination is a necessary proceeding which must be performed before admission to the academy of solo singing, and then during singers' education and career. The phoniatric protocol must include a minimal number of parameters, which can be

  1. Taxonomy for competency-based dental curricula. (United States)

    Beltrán-Neira, Roberto J; Beltrán-Aguilar, Eugenio D


    The objective of this article is to propose a classification of dental competencies. Interest in dental competencies has grown consistently during the last three decades. However, the dental education literature suggests that the term "competency" is understood and used differently by dental schools around the world. The taxonomic classification of dental competencies we propose follows a systematic approach starting at the highest level of complexity, i.e., the professional profile the teaching institution envisions for its graduates, and following in a decreasing degree of complexity to competency function, task, step, movement, and moment. This taxonomy has proved to be useful for more than thirty years in the Dental School of the Peruvian University Cayetano Heredia. Graduates of this school are successful practitioners, teachers, and researchers in Peru and other countries. The classification proposed here should clarify terms, facilitate curriculum design and learning assessment, stimulate further discussion on the matter, and facilitate communication among the dental education establishment.

  2. A taxonomy of integral reaction path analysis

    Energy Technology Data Exchange (ETDEWEB)

    Grcar, Joseph F.; Day, Marcus S.; Bell, John B.


    W. C. Gardiner observed that achieving understanding through combustion modeling is limited by the ability to recognize the implications of what has been computed and to draw conclusions about the elementary steps underlying the reaction mechanism. This difficulty can be overcome in part by making better use of reaction path analysis in the context of multidimensional flame simulations. Following a survey of current practice, an integral reaction flux is formulated in terms of conserved scalars that can be calculated in a fully automated way. Conditional analyses are then introduced, and a taxonomy for bidirectional path analysis is explored. Many examples illustrate the resulting path analysis and uncover some new results about nonpremixed methane-air laminar jets.

  3. Nematode taxonomy: from morphology to metabarcoding (United States)

    Ahmed, M.; Sapp, M.; Prior, T.; Karssen, G.; Back, M.


    Nematodes represent a species rich and morphologically diverse group of metazoans inhabiting both aquatic and terrestrial environments. Their role as biological indicators and as key players in nutrient cycling has been well documented. Some groups of nematodes are also known to cause significant losses to crop production. In spite of this, knowledge of their diversity is still limited due to the difficulty in achieving species identification using morphological characters. Molecular methodology has provided very useful means of circumventing the numerous limitations associated with classical morphology based identification. We discuss herein the history and the progress made within the field of nematode systematics, the limitations of classical taxonomy and how the advent of high throughput sequencing is facilitating advanced ecological and molecular studies.

  4. When Not to Go SOLO? Contraindications Based on Implant Experience. (United States)

    Wollersheim, Laurens W; Li, Wilson W; Kaya, Abdullah; van Boven, Wim J; van der Meulen, Jan; de Mol, Bas A


    Because of the design and specific implantation technique of the stentless Freedom SOLO bioprosthesis, patient selection is crucial. The aim of the study was to discuss the contraindications to this prosthesis based on the authors' implant experience. Between April 2005 and February 2015, one surgeon at the authors' center performed 292 aortic valve replacements using a bioprosthesis, with the initial intention of implanting a SOLO valve in every patient. A search was conducted for all of these patients and data collected on whether a SOLO valve was used, or not. A SOLO valve was implanted in 238 patients (82%), and a stented bioprosthesis in 54 (18%). The predominant reasons not to implant a SOLO valve were asymmetric commissures (26%) and a large aortic annulus (24%). Only one patient had structural valve deterioration, and none of the patients had to undergo reoperation because of aortic valve insufficiency or paravalvular leakage. Asymmetric commissures, large aortic annulus (>27 mm), calcified aortic sinuses, dilated sinotubular junction, aberrant location of coronary ostia and whenever the stent of a stented bioprosthesis is useful, were contraindications to implant a SOLO valve. When these contraindications were taken into account, a very good durability could be achieved with the SOLO valve during mid-term follow up.

  5. COPD: time to improve its taxonomy?

    Directory of Open Access Journals (Sweden)

    Bartolomé R. Celli


    Full Text Available Due to well-conducted epidemiological studies and advances in genetics, molecular biology, translational research, the advent of computed tomography of the lungs and bioinformatics, the diagnosis of chronic obstructive pulmonary disease (COPD as a single entity caused by susceptibility to cigarette smoke is no longer tenable. Furthermore, the once-accepted concept that COPD results from a rapid and progressive loss of lung function over time is not true for a sizeable proportion of adults with the disease. Now we know that some genetic predisposition and/or different environmental interactions (nutritional, infectious, pollution and immunological may negatively modulate post-natal lung development and lead to poorly reversible airflow limitation later in life, consistent with COPD. We believe it is time to rethink the taxonomy of this disease based on the evidence at hand. To do so, we have followed the principles outlined in the 1980s by J.D. Scadding who proposed that diseases can be defined by four key characteristics: 1 clinical description (syndrome, 2 disorder of structure (morbid anatomy, 3 disorder of function (pathophysiology and 4 causation (aetiology. Here, we propose a pragmatic approach to the taxonomy of COPD based on different processes that result in a similar syndromic presentation. It can accommodate changes over time, as the pathobiology that may lead to COPD expands. We hope that stakeholders in the field may find it useful to better define the patients now boxed into one single entity, so that specific studies can be designed and conducted for each type of COPDs.

  6. Tumor taxonomy for the developmental lineage classification of neoplasms

    International Nuclear Information System (INIS)

    Berman, Jules J


    The new 'Developmental lineage classification of neoplasms' was described in a prior publication. The classification is simple (the entire hierarchy is described with just 39 classifiers), comprehensive (providing a place for every tumor of man), and consistent with recent attempts to characterize tumors by cytogenetic and molecular features. A taxonomy is a list of the instances that populate a classification. The taxonomy of neoplasia attempts to list every known term for every known tumor of man. The taxonomy provides each concept with a unique code and groups synonymous terms under the same concept. A Perl script validated successive drafts of the taxonomy ensuring that: 1) each term occurs only once in the taxonomy; 2) each term occurs in only one tumor class; 3) each concept code occurs in one and only one hierarchical position in the classification; and 4) the file containing the classification and taxonomy is a well-formed XML (eXtensible Markup Language) document. The taxonomy currently contains 122,632 different terms encompassing 5,376 neoplasm concepts. Each concept has, on average, 23 synonyms. The taxonomy populates 'The developmental lineage classification of neoplasms,' and is available as an XML file, currently 9+ Megabytes in length. A representation of the classification/taxonomy listing each term followed by its code, followed by its full ancestry, is available as a flat-file, 19+ Megabytes in length. The taxonomy is the largest nomenclature of neoplasms, with more than twice the number of neoplasm names found in other medical nomenclatures, including the 2004 version of the Unified Medical Language System, the Systematized Nomenclature of Medicine Clinical Terminology, the National Cancer Institute's Thesaurus, and the International Classification of Diseases Oncolology version. This manuscript describes a comprehensive taxonomy of neoplasia that collects synonymous terms under a unique code number and assigns each

    The originality of this book, which deals with such a new subject matter, lies in the application of methods and concepts never used before - such as ontologies and taxonomies, as well as thesauri - to the ordering of knowledge based on primary information. Chapters in the book also examine the study of ontologies, taxonomies and thesauri from the perspective of systematics and general systems theory. Ontologies, Taxonomies and Thesauri in Systems Science and Systematics will be extremely useful to those operating within the network of related fields, which includes documentation and informati

  8. Solo and keratin filaments regulate epithelial tubule morphology. (United States)

    Nishimura, Ryosuke; Kato, Kagayaki; Fujiwara, Sachiko; Ohashi, Kazumasa; Mizuno, Kensaku


    Epithelial tubules, consisting of the epithelial cell sheet with a central lumen, are the basic structure of many organs. Mechanical forces play an important role in epithelial tubulogenesis; however, little is known about the mechanisms controlling the mechanical forces during epithelial tubule morphogenesis. Solo (also known as ARHGEF40) is a RhoA-targeting guanine-nucleotide exchange factor that is involved in mechanical force-induced RhoA activation and stress fiber formation. Solo binds to keratin-8/keratin-18 (K8/K18) filaments, and this interaction plays a crucial role in mechanotransduction. In this study, we examined the roles of Solo and K8/K18 filaments in epithelial tubulogenesis using MDCK cells cultured in 3D collagen gels. Knockdown of either Solo or K18 resulted in rounder tubules with increased lumen size, indicating that Solo and K8/K18 filaments play critical roles in forming the elongated morphology of epithelial tubules. Moreover, knockdown of Solo or K18 decreased the level of diphosphorylated myosin light chain (a marker of contractile force) at the luminal and outer surfaces of tubules, suggesting that Solo and K8/K18 filaments are involved in the generation of the myosin II-mediated contractile force during epithelial tubule morphogenesis. In addition, K18 filaments were normally oriented along the long axis of the tubule, but knockdown of Solo perturbed their orientation. These results suggest that Solo plays crucial roles in forming the elongated morphology of epithelial tubules and in regulating myosin II activity and K18 filament organization during epithelial tubule formation.

  9. Towards a Unified Taxonomy of Health Indicators: Academic Health Centers and Communities Working Together to Improve Population Health (United States)

    The Clinical and Translational Science Awards (CTSA) program represents a significant public investment. To realize its major goal of improving the public’s health and reducing health disparities, the CTSA Consortium’s Community Engagement Key Function Committee has undertaken the challenge of developing a taxonomy of community health indicators. The objective is to initiate a unified approach for monitoring progress in improving population health outcomes. Such outcomes include, importantly, the interests and priorities of community stakeholders, plus the multiple, overlapping interests of universities and of the public health and health care professions involved in the development and use of local health care indicators. The emerging taxonomy of community health indicators that the authors propose supports alignment of CTSA activities and facilitates comparative effectiveness research across CTSAs, thereby improving the health of communities and reducing health disparities. The proposed taxonomy starts at the broadest level, determinants of health; subsequently moves to more finite categories of community health indicators; and, finally, addresses specific quantifiable measures. To illustrate the taxonomy’s application, the authors have synthesized 21 health indicator projects from the literature and categorized them into international, national, or local/special jurisdictions. They furthered categorized the projects within the taxonomy by ranking indicators with the greatest representation among projects and by ranking the frequency of specific measures. They intend for the taxonomy to provide common metrics for measuring changes to population health and, thus, extend the utility of the CTSA Community Engagement Logic Model. The input of community partners will ultimately improve population health. PMID:24556775

  12. A taxonomy of behaviour change methods: an Intervention Mapping approach. (United States)

    Kok, Gerjo; Gottlieb, Nell H; Peters, Gjalt-Jorn Y; Mullen, Patricia Dolan; Parcel, Guy S; Ruiter, Robert A C; Fernández, María E; Markham, Christine; Bartholomew, L Kay


    In this paper, we introduce the Intervention Mapping (IM) taxonomy of behaviour change methods and its potential to be developed into a coding taxonomy. That is, although IM and its taxonomy of behaviour change methods are not in fact new, because IM was originally developed as a tool for intervention development, this potential was not immediately apparent. Second, in explaining the IM taxonomy and defining the relevant constructs, we call attention to the existence of parameters for effectiveness of methods, and explicate the related distinction between theory-based methods and practical applications and the probability that poor translation of methods may lead to erroneous conclusions as to method-effectiveness. Third, we recommend a minimal set of intervention characteristics that may be reported when intervention descriptions and evaluations are published. Specifying these characteristics can greatly enhance the quality of our meta-analyses and other literature syntheses. In conclusion, the dynamics of behaviour change are such that any taxonomy of methods of behaviour change needs to acknowledge the importance of, and provide instruments for dealing with, three conditions for effectiveness for behaviour change methods. For a behaviour change method to be effective: (1) it must target a determinant that predicts behaviour; (2) it must be able to change that determinant; (3) it must be translated into a practical application in a way that preserves the parameters for effectiveness and fits with the target population, culture, and context. Thus, taxonomies of methods of behaviour change must distinguish the specific determinants that are targeted, practical, specific applications, and the theory-based methods they embody. In addition, taxonomies should acknowledge that the lists of behaviour change methods will be used by, and should be used by, intervention developers. Ideally, the taxonomy should be readily usable for this goal; but alternatively, it should be

    Yang, Yun Seok; Kim, Seung Hyun; Jin, Chan Hee; Oh, Kwoan Young; Hur, Myung Haeng; Kim, Soo Young; Yim, Hyun Soon


    The objective of this study was to present the initial operative experience of solo surgeon single-port laparoscopic surgery (SPLS) in the laparoscopic treatment of benign gynecologic diseases and to investigate its feasibility and surgical outcomes. Using a novel homemade laparoscope-anchored instrument system that consisted of a laparoscopic instrument attached to a laparoscope and a glove-wound retractor umbilical port, we performed solo surgeon SPLS in 13 patients between March 2011 and June 2012. Intraoperative complications and postoperative surgical outcomes were determined. The primary operative procedures performed were unilateral salpingo-oophorectomy (n = 5), unilateral salpingectomy (n = 2), adhesiolysis (n = 1), and laparoscopically assisted vaginal hysterectomy (n = 5). Additional surgical procedures included additional adhesiolysis (n = 4) and ovarian drilling (n = 1).The primary indications for surgery were benign ovarian tumors (n = 5), ectopic pregnancy (n = 2), pelvic adhesion (infertility) (n = 1), and benign uterine tumors (n = 5). Solo surgeon SPLS was successfully accomplished in all procedures without a laparoscopic assistant. There were no intraoperative or postoperative complications. Our laparoscope-anchored instrument system obviates the need for an additional laparoscopic assistant and enables SPLS to be performed by a solo surgeon. The findings show that with our system, solo surgeon SPLS is a feasible and safe alternative technique for the treatment of benign gynecologic diseases in properly selected patients.

  17. A Taxonomy of Medical Uncertainties in Clinical Genome Sequencing (United States)

    Han, Paul K. J.; Umstead, Kendall L.; Bernhardt, Barbara A.; Green, Robert C.; Joffe, Steven; Koenig, Barbara; Krantz, Ian; Waterston, Leo B.; Biesecker, Leslie G.; Biesecker, Barbara B.


    Purpose Clinical next generation sequencing (CNGS) is introducing new opportunities and challenges into the practice of medicine. Simultaneously, these technologies are generating uncertainties of unprecedented scale that laboratories, clinicians, and patients are required to address and manage. We describe in this report the conceptual design of a new taxonomy of uncertainties around the use of CNGS in health care. Methods Interviews to delineate the dimensions of uncertainty in CNGS were conducted with genomics experts, and themes were extracted in order to expand upon a previously published three-dimensional taxonomy of medical uncertainty. In parallel we developed an interactive website to disseminate the CNGS taxonomy to researchers and engage them in its continued refinement. Results The proposed taxonomy divides uncertainty along three axes: source, issue, and locus, and further discriminates the uncertainties into five layers with multiple domains. Using a hypothetical clinical example, we illustrate how the taxonomy can be applied to findings from CNGS and used to guide stakeholders through interpretation and implementation of variant results. Conclusion The utility of the proposed taxonomy lies in promoting consistency in describing dimensions of uncertainty in publications and presentations, to facilitate research design and management of the uncertainties inherent in the implementation of CNGS.

  18. A profile of solo/two-physician practices. (United States)

    Lee, Doohee; Fiack, Kelly James; Knapp, Kenneth Michael


    Understanding practice behaviors of solo/dual physician ownership and associated factors at the national level is important information for policymakers and clinicians in response to the Affordable Care Act (ACA) of 2010, but poorly understood in the literature. We analyzed nationally representative data (n = 4,720). The study results reveal nearly 33% of the sample reported solo/two-physician practices. Male/minority/older physicians, psychiatrists, favor small practices. Greater market competition was perceived and less charity care was given among solo/two-physician practitioners. The South region was favored by small physician practitioners. Physicians in solo or two-person practices provided fewer services to chronic patients and were dissatisfied with their overall career in medicine. Small practices were favored by international medical graduates (IMGs) and primary care physicians (PCPs). Overall our data suggest that the role of solo/dual physician practices is fading away in the delivery of medicine. Our findings shed light on varied characteristics and practice behaviors of solo/two-physician practitioners, but more research may be needed to reevaluate the potential role of small physician practitioners and find a way to foster a private physician practice model in the context of the newly passed ACA of 2010.

    The taxonomic crisis, emphasized in recent years, is marked by the lack of popularity (lack of interest in taxonomy) and financial incentives to study biodiversity. This situation, coupled with the issues involved with the necessity of knowing many yet undiscovered species, has meant that new technologies, including the use of DNA, have emerged to revitalize taxonomy. Part of the scientific community, however, has rejected the use of these innovative ideas. DNA barcoding has especially been t...

  20. The ACTTION-American Pain Society Pain Taxonomy (AAPT): an evidence-based and multidimensional approach to classifying chronic pain conditions. (United States)

    Fillingim, Roger B; Bruehl, Stephen; Dworkin, Robert H; Dworkin, Samuel F; Loeser, John D; Turk, Dennis C; Widerstrom-Noga, Eva; Arnold, Lesley; Bennett, Robert; Edwards, Robert R; Freeman, Roy; Gewandter, Jennifer; Hertz, Sharon; Hochberg, Marc; Krane, Elliot; Mantyh, Patrick W; Markman, John; Neogi, Tuhina; Ohrbach, Richard; Paice, Judith A; Porreca, Frank; Rappaport, Bob A; Smith, Shannon M; Smith, Thomas J; Sullivan, Mark D; Verne, G Nicholas; Wasan, Ajay D; Wesselmann, Ursula


    Current approaches to classification of chronic pain conditions suffer from the absence of a systematically implemented and evidence-based taxonomy. Moreover, existing diagnostic approaches typically fail to incorporate available knowledge regarding the biopsychosocial mechanisms contributing to pain conditions. To address these gaps, the Analgesic, Anesthetic, and Addiction Clinical Trial Translations Innovations Opportunities and Networks (ACTTION) public-private partnership with the U.S. Food and Drug Administration and the American Pain Society (APS) have joined together to develop an evidence-based chronic pain classification system called the ACTTION-APS Pain Taxonomy. This paper describes the outcome of an ACTTION-APS consensus meeting, at which experts agreed on a structure for this new taxonomy of chronic pain conditions. Several major issues around which discussion revolved are presented and summarized, and the structure of the taxonomy is presented. ACTTION-APS Pain Taxonomy will include the following dimensions: 1) core diagnostic criteria; 2) common features; 3) common medical comorbidities; 4) neurobiological, psychosocial, and functional consequences; and 5) putative neurobiological and psychosocial mechanisms, risk factors, and protective factors. In coming months, expert working groups will apply this taxonomy to clusters of chronic pain conditions, thereby developing a set of diagnostic criteria that have been consistently and systematically implemented across nearly all common chronic pain conditions. It is anticipated that the availability of this evidence-based and mechanistic approach to pain classification will be of substantial benefit to chronic pain research and treatment. The ACTTION-APS Pain Taxonomy is an evidence-based chronic pain classification system designed to classify chronic pain along the following dimensions: 1) core diagnostic criteria; 2) common features; 3) common medical comorbidities; 4) neurobiological, psychosocial

  1. The feasibility of single-port laparoscopic appendectomy using a solo approach: a comparative study. (United States)

    Kim, Say-June; Choi, Byung-Jo; Jeong, Wonjun; Lee, Sang Chul


    To investigate the feasibility and safety of solo surgery with single-port laparoscopic appendectomy, which is termed herein solo-SPLA (solo-single-port laparoscopic appendectomy). This study prospectively collected and retrospectively analyzed data from patients who had undergone either non-solo-SPLA (n = 150) or solo-SPLA (n = 150). Several devices were utilized for complete, skin-to-skin solo-SPSA, including a Lone Star Retractor System and an adjustable mechanical camera holder. Operating times were not significantly different between solo- and non-solo-SPLA (45.0 ± 21.0 minutes vs. 46.7 ± 26.1 minutes, P = 0.646). Most postoperative variables were also comparable between groups, including the necessity for intravenous analgesics (0.7 ± 1.2 ampules [solo-SPLA] vs. 0.9 ± 1.5 ampules [non-solo-SPLA], P = 0.092), time interval to gas passing (1.3 ± 1.0 days vs. 1.4 ± 1.0 days, P = 0.182), and the incidence of postoperative complications (4.0% vs. 8.7%, P = 0.153). Moreover, solo-SPLA effectively lowered the operating cost by reducing surgical personnel expenses. Solo-SPLA economized staff numbers and thus lowered hospital costs without lengthening of operating time. Therefore, solo-SPLA could be considered a safe and feasible alternative to non-solo-SPLA.

  2. Census of solo LuxR genes in prokaryotic genomes. (United States)

    Hudaiberdiev, Sanjarbek; Choudhary, Kumari S; Vera Alvarez, Roberto; Gelencsér, Zsolt; Ligeti, Balázs; Lamba, Doriano; Pongor, Sándor


    luxR genes encode transcriptional regulators that control acyl homoserine lactone-based quorum sensing (AHL QS) in Gram negative bacteria. On the bacterial chromosome, luxR genes are usually found next or near to a luxI gene encoding the AHL signal synthase. Recently, a number of luxR genes were described that have no luxI genes in their vicinity on the chromosome. These so-called solo luxR genes may either respond to internal AHL signals produced by a non-adjacent luxI in the chromosome, or can respond to exogenous signals. Here we present a survey of solo luxR genes found in complete and draft bacterial genomes in the NCBI databases using HMMs. We found that 2698 of the 3550 luxR genes found are solos, which is an unexpectedly high number even if some of the hits may be false positives. We also found that solo LuxR sequences form distinct clusters that are different from the clusters of LuxR sequences that are part of the known luxR-luxI topological arrangements. We also found a number of cases that we termed twin luxR topologies, in which two adjacent luxR genes were in tandem or divergent orientation. Many of the luxR solo clusters were devoid of the sequence motifs characteristic of AHL binding LuxR proteins so there is room to speculate that the solos may be involved in sensing hitherto unknown signals. It was noted that only some of the LuxR clades are rich in conserved cysteine residues. Molecular modeling suggests that some of the cysteines may be involved in disulfide formation, which makes us speculate that some LuxR proteins, including some of the solos may be involved in redox regulation.

  3. A taxonomy of control in intensified processes

    International Nuclear Information System (INIS)

    Barzin, R.; Abd Shukor, S.R.; Ahmad, A.L.


    Process Intensification (PI) is a revolutionary approach to design, development and implementation of process and plant. PI technology offers improved environment in a chemical process in terms of better products, and processes which are safer, cleaner, smaller - and cheaper. PI is a strategy of making dramatic reductions in the size of unit operations within chemical plants, in order to achieve given production objectives. However, PI technology would be handicapped if such system is not properly controlled. There are some foreseeable problems in order to control such processes for instance, dynamic interaction between components that make up a control loop, response time of the instrumentations, availability of proper sensor and etc. In some cases, in order to control these systems, advanced control solutions have been applied i.e. model predictive controllers (MPC) and its different algorithms such as quadratic generalized predictive control (QGPC) and self tuning quadratic generalized predictive control (STQGPC). Nevertheless in some cases simpler solutions could be applied to control such system for example proportional integral controller in the control of reactive distillation systems. As mentioned, conventional control systems like proportional-integral, proportional-integral-derivative (PID) controllers and their different structures can be used in PI systems but due to inherent nonlinearity and fast responsiveness of PI systems, digital controllers-regarding to their robustness-are mostly applied in order to control PI systems. Regarding to the fact that choosing the appropriate control strategy is the most essential part of making PI systems possible to be handle easily, taxonomy of the usage of various control structure in controlling PI systems is proposed. This paper offers an overview and discussion on identifying potential problems of instrumentation in PI technology and available control strategies

  4. Instruments and Taxonomy of Workplace Bullying in Health Care Organizations

    Directory of Open Access Journals (Sweden)

    Eun-Jun Park, PhD, RN


    Full Text Available Summary: Purpose: This study was aimed to evaluate the methodological issues and comprehensiveness of workplace bullying instruments and to suggest a taxonomy of psychological abuse. Methods: Nineteen instruments applied in health care organizations and 469 questionnaire items mainly regarding psychological abuse were collected through a literature review. Three researchers classified the questionnaire items according to a “taxonomy of psychological abuse in the workplace.” Results: Many instruments of workplace bullying were developed in the 2000s using a reflective measurement model, but their psychometric property was not sufficient and the measurement model is questioned. Based on the questionnaire items, the “taxonomy of psychological abuse in the workplace” was modified by adding two new subcategories (unachievable work and unfair treatment and clarifying some operational definitions. According to the modified taxonomy of 11 (subcategories, the reviewed instruments assessed 6.5 (subcategories on average. No instrument measured all (subcategories. Category 4.2 (disrespect, humiliation, and rejection of the person was measured in all instruments, followed by Categories 5 (professional discredit and denigration and 1.2 (social isolation behaviors. Conclusion: The current instruments are not comprehensive enough. It is suggested that the modified taxonomy is verified and guide more reliable and inclusive instruments in the future. Furthermore, a formative measurement model, which defines a bullying as an inventory of different types of behaviors, should be used. Keywords: aggression, bullying, hostility, mobbing, surveys and questionnaires

  5. Climbing Bloom's taxonomy pyramid: Lessons from a graduate histology course. (United States)

    Zaidi, Nikki B; Hwang, Charles; Scott, Sara; Stallard, Stefanie; Purkiss, Joel; Hortsch, Michael


    Bloom's taxonomy was adopted to create a subject-specific scoring tool for histology multiple-choice questions (MCQs). This Bloom's Taxonomy Histology Tool (BTHT) was used to analyze teacher- and student-generated quiz and examination questions from a graduate level histology course. Multiple-choice questions using histological images were generally assigned a higher BTHT level than simple text questions. The type of microscopy technique (light or electron microscopy) used for these image-based questions did not result in any significant differences in their Bloom's taxonomy scores. The BTHT levels for teacher-generated MCQs correlated positively with higher discrimination indices and inversely with the percent of students answering these questions correctly (difficulty index), suggesting that higher-level Bloom's taxonomy questions differentiate well between higher- and lower-performing students. When examining BTHT scores for MCQs that were written by students in a Multiple-Choice Item Development Assignment (MCIDA) there was no significant correlation between these scores and the students' ability to answer teacher-generated MCQs. This suggests that the ability to answer histology MCQs relies on a different skill set than the aptitude to construct higher-level Bloom's taxonomy questions. However, students significantly improved their average BTHT scores from the midterm to the final MCIDA task, which indicates that practice, experience and feedback increased their MCQ writing proficiency.

  6. An Analytical Overview of Spirituality in NANDA-I Taxonomies. (United States)

    Mesquita, Ana Cláudia; Caldeira, Sílvia; Chaves, Erika; Carvalho, Emilia Campos de


    To discuss the approach of spirituality in NANDA-I taxonomies, based on the elements that characterize this phenomenon. This study was based on concepts that are usually adopted in the literature for defining spirituality and on the analysis of the NANDA-I taxonomies from I to III. Spirituality is included in all taxonomies but all three are missing some attributes to guarantee the completeness of this dimension for nursing diagnosis. Taxonomy III makes different approaches to spirituality and some inconsistencies. Contribute to the development and review of the new proposal for taxonomy. Discutir a abordagem à espiritualidade nas taxonomias da NANDA-I, baseada nos elementos que caracterizam este fenômeno. MÉTODOS: Este estudo foi baseado em conceitos usualmente adotados na literatura de enfermagem para definir espiritualidade e na análise das taxonomias da NANDA-I, desde a I à III. A espiritualidade está incluída nas taxonomias, porém estas carecem de atributos do seu conceito. CONCLUSÕES: A taxonomia III faz diferentes abordagens à espiritualidade, porém com algumas inconsistências identificadas. IMPLICAÇÕES PARA A ENFERMAGEM: Esta análise pode contribuir para o desenvolvimento e revisão da taxonomia III. © 2017 NANDA International, Inc.

  7. Latino Solo Grandparents Raising Grandchildren: Health Risks and Behaviors. (United States)

    Whitley, Deborah M; Fuller-Thomson, Esme


    The purpose of this descriptive report is to provide the first representative information on the sociodemographic profile and the prevalence of mental and physical health conditions of two "at-risk" groups of Latino caregivers: solo grandparent caregivers and single parents. The 2012 Behavior Risk Factor Surveillance System was used to compare five dimensions of health on a sample of Latino solo grandparents and Latino single parents, raising their grandchildren/children alone. Bivariate and logistic regression comparative analyses were conducted on study measures. Latino solo grandparents have a high prevalence of chronic health conditions, including arthritis (51%), depression (40%), diabetes (34%), and asthma (34%). Latino single parents have lower but troubling health risks, including depression (22%), diabetes (14%), and asthma (14%). Differences between the two groups were largely due to the grandparents older age. Latino solo grandparents have a high prevalence of several chronic medical conditions. The prevalence of disorders is much lower for Latino single parents, although they too have disturbing health risks. Latino solo grandparents perform their parenting role under intense physical and emotional strain. Health professionals can be instrumental in facilitating interventions that affect the well-being of this expanding family group.

    What do you think of when you think of taxonomy? An 18th century gentlemen in breeches? Or perhaps botany drawings hung on the walls of a boutique hotel? Such old-fashioned conceptions to the contrary, taxonomy is alive today although constantly struggling for survival and recognition. The scientific community is losing valuable resources as taxonomy experts age and retire, and funding for morphological studies and species descriptions remains stagnant. At the same time, organismal knowledge (morphology, ecology, physiology) has never been more important: genomic studies are becoming more taxon focused, the scientific community is recognizing the limitations of traditional “model” organisms, and taxonomic expertise is desperately needed to fight against global biodiversity declines resulting from human impacts. There has never been a better time for a taxonomic renaissance. PMID:28820884

  12. VecScreen_plus_taxonomy: imposing a tax(onomy) increase on vector contamination screening. (United States)

    Schäffer, Alejandro A; Nawrocki, Eric P; Choi, Yoon; Kitts, Paul A; Karsch-Mizrachi, Ilene; McVeigh, Richard


    Nucleic acid sequences in public databases should not contain vector contamination, but many sequences in GenBank do (or did) contain vectors. The National Center for Biotechnology Information uses the program VecScreen to screen submitted sequences for contamination. Additional tools are needed to distinguish true-positive (contamination) from false-positive (not contamination) VecScreen matches. A principal reason for false-positive VecScreen matches is that the sequence and the matching vector subsequence originate from closely related or identical organisms (for example, both originate in Escherichia coli). We collected information on the taxonomy of sources of vector segments in the UniVec database used by VecScreen. We used that information in two overlapping software pipelines for retrospective analysis of contamination in GenBank and for prospective analysis of contamination in new sequence submissions. Using the retrospective pipeline, we identified and corrected over 8000 contaminated sequences in the nonredundant nucleotide database. The prospective analysis pipeline has been in production use since April 2017 to evaluate some new GenBank submissions. Data on the sources of UniVec entries were included in release 10.0 ( The main software is freely available at Supplementary data are available at Bioinformatics online. Published by Oxford University Press 2017. This work is written by US Government employees and are in the public domain in the US.

  16. Modern Grid Initiative Distribution Taxonomy Final Report

    Energy Technology Data Exchange (ETDEWEB)

    Schneider, Kevin P.; Chen, Yousu; Chassin, David P.; Pratt, Robert G.; Engel, David W.; Thompson, Sandra E.


    This is the final report for the development of a toxonomy of prototypical electrical distribution feeders. Two of the primary goals of the Department of Energy's (DOE) Modern Grid Initiative (MGI) are 'to accelerate the modernization of our nation's electricity grid' and to 'support demonstrations of systems of key technologies that can serve as the foundation for an integrated, modern power grid'. A key component to the realization of these goals is the effective implementation of new, as well as existing, 'smart grid technologies'. Possibly the largest barrier that has been identified in the deployment of smart grid technologies is the inability to evaluate how their deployment will affect the electricity infrastructure, both locally and on a regional scale. The inability to evaluate the impacts of these technologies is primarily due to the lack of detailed electrical distribution feeder information. While detailed distribution feeder information does reside with the various distribution utilities, there is no central repository of information that can be openly accessed. The role of Pacific Northwest National Laboratory (PNNL) in the MGI for FY08 was to collect distribution feeder models, in the SynerGEE{reg_sign} format, from electric utilities around the nation so that they could be analyzed to identify regional differences in feeder design and operation. Based on this analysis PNNL developed a taxonomy of 24 prototypical feeder models in the GridLAB-D simulations environment that contain the fundamental characteristics of non-urban core, radial distribution feeders from the various regions of the U.S. Weighting factors for these feeders are also presented so that they can be used to generate a representative sample for various regions within the United States. The final product presented in this report is a toolset that enables the evaluation of new smart grid technologies, with the ability to aggregate their effects

  17. Social characteristics of a sample of solo mothers. (United States)

    Ritchie, J


    In 1978 a sample of 158 solo mothers was interviewed by third year psychology students under the supervision of the author to obtain data both on their child rearing practices (for comparison with data obtained the year before from a sample of dual parents) and on their social circumstances. These data indicate that in the case of women who had previously been married, most aspects of their life, with the exception of finance, are now improved. Freedom from conflict and greater independence are cited as the advantages of being a solo parent; loneliness and responsibility are the major disadvantages. Parents and friends are the chief sources of support.

Entretanto, o pisoteio animal e, ou, o preparo de solo podem compactá-lo, prejudicando o crescimento radicular e a produtividade das plantas. Estudaram-se os efeitos do pisoteio animal em regime de pastejo contínuo durante o inverno/primavera e do impacto do plantio direto e do preparo convencional de solo no estado de compactação, atributos químicos e distribuição radicular. Em Podzólico Vermelho-Amarelo de textura superficial franca, foi implantada uma pastagem de estação fria composta por aveia (Avena strigosa Schreb e azevém (Lolium multiflorum L.. A carga animal variou conforme o crescimento da pastagem. Em dezembro de 1996, foi implantada a cultura do milho (Zea mays L. para a produção de silagem, usando os seguintes tratamentos: plantio direto na área não pastejada, plantio direto após o pastejo, preparo convencional de solo na área não pastejada e preparo convencional de solo após pastejo. As avaliações apresentadas neste estudo são referentes ao terceiro ano de cultivo, no qual houve um período de pastejo de 107 dias. Aos 45 dias da emergência do milho, foram abertas trincheiras (100 x 40 cm para visualizar a distribuição do sistema radicular e coletar amostras de solo, a cada 5 cm, para caracterização química e determinação da densidade do solo e de raízes. Ao longo do perfil (0-40 cm, o desenho da distribuição de raízes indicou maior quantidade de raízes no preparo convencional de solo, concordando com os resultados de densidade de raízes. O pisoteio animal não teve efeito sobre as características físicas, possivelmente pelo fato de o resíduo da pastagem permanecer próximo a 1,0 Mg ha-1 de matéria seca. A densidade do solo no plantio direto, na camada de 5-10 cm, foi de 1,41 Mg m-3, tanto na área pastejada como na não pastejada. No preparo convencional de solo, esses valores foram de 1,15 Mg m-3

  19. An error taxonomy system for analysis of haemodialysis incidents. (United States)

    Gu, Xiuzhu; Itoh, Kenji; Suzuki, Satoshi


    This paper describes the development of a haemodialysis error taxonomy system for analysing incidents and predicting the safety status of a dialysis organisation. The error taxonomy system was developed by adapting an error taxonomy system which assumed no specific specialty to haemodialysis situations. Its application was conducted with 1,909 incident reports collected from two dialysis facilities in Japan. Over 70% of haemodialysis incidents were reported as problems or complications related to dialyser, circuit, medication and setting of dialysis condition. Approximately 70% of errors took place immediately before and after the four hours of haemodialysis therapy. Error types most frequently made in the dialysis unit were omission and qualitative errors. Failures or complications classified to staff human factors, communication, task and organisational factors were found in most dialysis incidents. Device/equipment/materials, medicine and clinical documents were most likely to be involved in errors. Haemodialysis nurses were involved in more incidents related to medicine and documents, whereas dialysis technologists made more errors with device/equipment/materials. This error taxonomy system is able to investigate incidents and adverse events occurring in the dialysis setting but is also able to estimate safety-related status of an organisation, such as reporting culture. © 2014 European Dialysis and Transplant Nurses Association/European Renal Care Association.

  14. Economic impact of dental hygienists on solo dental practices. (United States)

    Lazar, Vickie F; Guay, Albert H; Beazoglou, Tryfon J


    The fact that a significant percentage of dentists employ dental hygienists raises an important question: Are dental practices that utilize a dental hygienist structurally and operationally different from practices that do not? This article explores differences among dental practices that operate with and without dental hygienists. Using data from the American Dental Association's 2003 Survey of Dental Practice, a random sample survey of U.S. dentists, descriptive statistics were used to compare selected characteristics of solo general practitioners with and without dental hygienists. Multivariate regression analysis was used to estimate the effect of dental hygienists on the gross billings and net incomes of solo general practitioners. Differences in practice characteristics--such as hours spent in the practice and hours spent treating patients, wait time for a recall visit, number of operatories, square feet of office space, net income, and gross billings--were found between solo general practitioners who had dental hygienists and those who did not. Solo general practitioners with dental hygienists had higher gross billings. Higher gross billings would be expected, as would higher expenses. However, net incomes of those with dental hygienists were also higher. In contrast, the mean waiting time for a recall visit was higher among dentists who employed dental hygienists. Depending on personal preferences, availability of qualified personnel, etc., dentists who do not employ dental hygienists but have been contemplating that path may want to further research the benefits and opportunities that may be realized.

  15. "Telling a Story." On the Dramaturgy of Monophonic Jazz Solos

    Directory of Open Access Journals (Sweden)

    Klaus Frieler


    Full Text Available The metaphor of storytelling is widespread among jazz performers and jazz researchers. However, little is known about the precise meaning of this metaphor on an analytical level. The present paper attempts to shed light on the connected semantic field of the metaphor and relate it to its musical basis by investigating time courses of selected musical elements and features in monophonic jazz improvisations. Three explorative studies are carried out using transcriptions of 299 monophonic jazz solos from the Weimar Jazz Database. The first study inspects overall trends using fits of quadratic polynomials onto loudness and pitch curves. The second study does the same using selected features related to intensity, tension and variability over the course of phrases in the solos. The third study examines the distribution of the relative positions of various improvisational ideas in a subset of 116 solos. Results show that certain trends can be found, but not to a large extent. Significant trends most often display arch-shaped curves as expected from classical dramatic models. This is also in accordance with the fact that expressive improvisational ideas are more often found in the last part of a solo, while more relaxed ideas occur earlier. All in all, jazz improvisations show a wide range of variation and no single overarching dramatic model could be identified.

  20. Application of Modern Experimental Technique to Solve Morphological Complexity in Plants Taxonomy

    Directory of Open Access Journals (Sweden)



    Full Text Available Modern taxonomy has two approaches, i.e. classical and experimental taxonomy. Classical taxonomy uses morphological characters, while experimental taxonomy uses broader methods including chemistry, physics and mathematics, in the form of laboratory data that are revealed together with the progress of optical technique (microscope, chemistry methods (chromatography, electrophoresis, etc. Modern taxonomy tends to use series of interrelated data. More data used would result in more validity and give better clarification of taxonomic status. A lot of modern taxonomic data such as palynology, cytotaxonomy (cytology, chemical constituent (chemotaxonomy, isozyme and DNA sequencing were used recently.

    Full Text Available Indonesia's modern consumer societies develop in conjunction with the history of global economy and the transformation of consumer capitalism. This happens in many communities in cities of Indonesia, including Solo. With a population of 500 thousand at night and 1.5 million during the day, it is a potential market for global products. Therefore, it is obvious if the Solo people's tastes are no different than other communities, because of the consumer behaviour and global economy that are intertwined. The value of the meaning of products have also shifted, such as with cars. Cars that usually function as a vehicle no different than a wagon, have changed into a symbol of social class for the modern society, even for the people of Solo. The functions and facilities of the Various brands and types of cars, and elements that are related to automotive technology, are not too different. What makes the difference between these cars lays on the design of the form and image. This form design is able to create an image for certain social class for its user and its product brand. The most interesting phenomenon from automotive products in Indonesia is what happened with Toyota Kijang. Since its launch on 1977, Toyota Kijang, which is on its fifth generation this year, has succeeded in becoming the number one choice for cars for Indonesians.

    There is a need to expand the current temporomandibular disorders' (TMDs) classification to include less common but clinically important disorders. The immediate aim was to develop a consensus-based classification system and associated diagnostic criteria that have clinical and research utility for less common TMDs. The long-term aim was to establish a foundation, vis-à-vis this classification system, that will stimulate data collection, validity testing and further criteria refinement. A working group [members of the International RDC/TMD Consortium Network of the International Association for Dental Research (IADR), members of the Orofacial Pain Special Interest Group (SIG) of the International Association for the Study of Pain (IASP), and members from other professional societies] reviewed disorders for inclusion based on clinical significance, the availability of plausible diagnostic criteria and the ability to operationalise and study the criteria. The disorders were derived from the literature when possible and based on expert opinion as necessary. The expanded TMDs taxonomy was presented for feedback at international meetings. Of 56 disorders considered, 37 were included in the expanded taxonomy and were placed into the following four categories: temporomandibular joint disorders, masticatory muscle disorders, headache disorders and disorders affecting associated structures. Those excluded were extremely uncommon, lacking operationalised diagnostic criteria, not clearly related to TMDs, or not sufficiently distinct from disorders already included within the taxonomy. The expanded TMDs taxonomy offers an integrated approach to clinical diagnosis and provides a framework for further research to operationalise and test the proposed taxonomy and diagnostic criteria. © 2014 John Wiley & Sons Ltd.

  3. A philosophical taxonomy of ethically significant moral distress. (United States)

    Thomas, Tessy A; McCullough, Laurence B


    Moral distress is one of the core topics of clinical ethics. Although there is a large and growing empirical literature on the psychological aspects of moral distress, scholars, and empirical investigators of moral distress have recently called for greater conceptual clarity. To meet this recognized need, we provide a philosophical taxonomy of the categories of what we call ethically significant moral distress: the judgment that one is not able, to differing degrees, to act on one's moral knowledge about what one ought to do. We begin by unpacking the philosophical components of Andrew Jameton's original formulation from his landmark 1984 work and identify two key respects in which that formulation remains unclear: the origins of moral knowledge and impediments to acting on that moral knowledge. We then selectively review subsequent literature that shows that there is more than one concept of moral distress and that explores the origin of the values implicated in moral distress and impediments to acting on those values. This review sets the stage for identifying the elements of a philosophical taxonomy of ethically significant moral distress. The taxonomy uses these elements to create six categories of ethically significant moral distress: challenges to, threats to, and violations of professional integrity; and challenges to, threats to, and violations of individual integrity. We close with suggestions about how the proposed philosophical taxonomy of ethically significant moral distress sheds light on the concepts of moral residue and crescendo effect of moral distress and how the proposed taxonomy might usefully guide prevention of and future qualitative and quantitative empirical research on ethically significant moral distress. © The Author 2014.

  4. A taxonomy of epithelial human cancer and their metastases

    Directory of Open Access Journals (Sweden)

    De Moor Bart


    . Moreover, a signature was developed based on our unsupervised clustering of breast tumors and this was predictive for disease-specific survival in three independent studies. Next, the metastases from ovarian, breast, lung and vulva cluster with their tissue of origin while metastases from colon showed a bimodal distribution. A significant part clusters with tissue of origin while the remaining tumors cluster with the tissue of destination. Conclusion Our molecular taxonomy of epithelial human cancer indicates surprising correlations over tissues. This may have a significant impact on the classification of many cancer sites and may guide pathologists, both in research and daily practice. Moreover, these results based on unsupervised analysis yielded a signature predictive of clinical outcome in breast cancer. Additionally, we hypothesize that metastases from gastrointestinal origin either remember their tissue of origin or adapt to the tissue of destination. More specifically, colon metastases in the liver show strong evidence for such a bimodal tissue specific profile.

  5. Fail or flourish? Cognitive appraisal moderates the effect of solo status on performance. (United States)

    White, Judith B


    When everyone in a group shares a common social identity except one individual, the one who is different from the majority has solo status. Solo status increases one's visibility and performance pressure, which may result in stress. Stress has divergent effects on performance, and individuals' response to stressful situations is predicted by their cognitive appraisal (challenge or threat) of the situation. Two experiments test the hypothesis that cognitive appraisal moderates the effect of solo status on performance. Experiment 1 finds that at relatively high appraisal levels (resources exceed demands), solo status improves men's and women's performance; at relatively low appraisal levels, solo status hurts performance. Experiment 2 replicates this effect for solo status based on minimal group assignment. Results suggest that for individuals who feel challenged and not threatened by their work, it may help to be a solo.

  6. Taxonomy of Means and Ends in Aquaculture Production—Part 2: The Technical Solutions of Controlling Solids, Dissolved Gasses and pH

    Directory of Open Access Journals (Sweden)

    Bjorgvin Vilbergsson


    Full Text Available In engineering design, knowing the relationship between the means (technique and the end (desired function or outcome is essential. The means in Aquaculture are technical solutions like airlifts that are used to achive desired functionality (an end like controlling dissolved gasses. In previous work, the authors identified possible functions by viewing aquaculture production systems as transformation processes in which inputs are transformed by treatment techniques (means and produce outputs (ends. The current work creates an overview of technical solutions of treatment functions for both design and research purposes. A comprehensive literature review of all areas of technical solutions is identified and categorized into a visual taxonomy of the treatment functions for controlling solids, controlling dissolved gasses and controlling pH alkalinity and hardness. This article is the second in a sequence of four and partly presents the treatments functions in the taxonomy. The other articles in this series present complementary aspects of this research: Part 1, A transformational view on aquaculture and functions divided into input, treatment and output functions; Part 2, The current taxonomy paper; Part 3, The second part of the taxonomy; and Part 4, Mapping of the means (techniques for multiple treatment functions.

    Full Text Available Para avaliar a viabilidade da implantação da cultura do milho em solo sob preparo reduzido, em dezembro de 1988, instalou-se um experimento em um Latossolo Vermelho-Escuro distrófico, no município de Passo Fundo (RS. Na testemunha, o preparo do solo foi realizado por meio de uma escarificação mais uma gradagem com grade leve. Nos demais cinco tratamentos, o solo foi preparado por meio de uma operação conjugada (escarificador equipado com rolo destorroador. Na testemunha e em um dos tratamentos sob preparo conjugado, não foram realizadas adaptações na semeadora-adubadora. Nos demais tratamentos, foram adaptados discos de corte ondulados, ou secções de rolos destorroadores, na frente das linhas da semeadora. A percentagem de cobertura do solo, dois dias após a semeadura, foi significativamente menor (Tukey ao nível de 5% na testemunha, enquanto nos demais tratamentos, caracterizados como conservacionistas, não se perceberam diferenças. O diâmetro médio geométrico (DMG dos agregados do solo não apresentou diferenças significativas entre os tratamentos, porém os agregados coletados nas linhas apresentaram DMG significativamente menores do que aqueles encontrados nas entrelinhas. A velocidade de absorção de água pelas sementes, o comprimento médio ponderado das radículas, o índice de velocidade de emergência e o estande inicial de plantas de milho não variaram significativamente em função dos tratamentos. Os resultados evidenciam que o preparo conjugado do solo por meio de um escarificador equipado com um cilindro destorroador permitiu implantar a cultura do milho, sem a necessidade de operações de preparo secundário (gradagens e sem requerer adaptações na semeadora-adubadora.

    Dutra, Jayne E.


    This viewgraph presentation reviews the concept of developing taxonomies for an information architecture. In order to assist people in accessing information required to access information and retrieval, including cross repository searching, a system of nested taxonomies is being developed. Another facet of this developmental project is collecting and documenting attributes about people, to allow for several uses: access management, i.e., who are you and what can you see?; targeted content delivery i.e., what content helps you get your work done?; w ork force planning i.e., what skill sets do you have that we can appl y to work?; and IT Services i.e., How can we provision you with the proper IT services?

  9. Current taxonomy of phages infecting lactic acid bacteria

    Directory of Open Access Journals (Sweden)

    Jennifer eMahony


    Full Text Available Phages infecting lactic acid bacteria have been the focus of significant research attention over the past three decades. Through the isolation and characterization of hundreds of phage isolates, it has been possible to classify phages of the dairy starter and adjunct bacteria Lactococus lactis, Streptococcus thermophilus, Leuconostoc spp. and Lactobacillus spp. Among these, phages of L. lactis have been most thoroughly scrutinized and serve as an excellent model system to address issues that arise when attempting taxonomic classification of phages infecting other LAB species. Here, we present an overview of the current taxonomy of phages infecting LAB genera of industrial significance, the methods employed in these taxonomic efforts and how these may be employed for the taxonomy of phages of currently underrepresented and emerging phage species.

  10. NASA Taxonomies for Searching Problem Reports and FMEAs (United States)

    Malin, Jane T.; Throop, David R.


    Many types of hazard and risk analyses are used during the life cycle of complex systems, including Failure Modes and Effects Analysis (FMEA), Hazard Analysis, Fault Tree and Event Tree Analysis, Probabilistic Risk Assessment, Reliability Analysis and analysis of Problem Reporting and Corrective Action (PRACA) databases. The success of these methods depends on the availability of input data and the analysts knowledge. Standard nomenclature can increase the reusability of hazard, risk and problem data. When nomenclature in the source texts is not standard, taxonomies with mapping words (sets of rough synonyms) can be combined with semantic search to identify items and tag them with metadata based on a rich standard nomenclature. Semantic search uses word meanings in the context of parsed phrases to find matches. The NASA taxonomies provide the word meanings. Spacecraft taxonomies and ontologies (generalization hierarchies with attributes and relationships, based on terms meanings) are being developed for types of subsystems, functions, entities, hazards and failures. The ontologies are broad and general, covering hardware, software and human systems. Semantic search of Space Station texts was used to validate and extend the taxonomies. The taxonomies have also been used to extract system connectivity (interaction) models and functions from requirements text. Now the Reconciler semantic search tool and the taxonomies are being applied to improve search in the Space Shuttle PRACA database, to discover recurring patterns of failure. Usual methods of string search and keyword search fall short because the entries are terse and have numerous shortcuts (irregular abbreviations, nonstandard acronyms, cryptic codes) and modifier words cannot be used in sentence context to refine the search. The limited and fixed FMEA categories associated with the entries do not make the fine distinctions needed in the search. The approach assigns PRACA report titles to problem classes in

  11. little sister: An Afro-Temporal Solo-Play. (United States)

    De Berry, Misty


    little sister: An Afro-Temporal Solo-Play is at once a memory-scape and a mytho-biography set to poetry, movement, and mixed media. A performance poem spanning from the Antebellum South to present-moment Chicago, it tells the story of a nomadic spirit named little-she who shape-shifts through the memories and imaginings of her sister, the narrator. Through the characters little-she and the narrator, the solo-performance explores embodied ways to rupture and relieve the impact of macro forms of violence in the micro realm of the everyday. To this end, little sister witnesses and disrupts the legacy of violence in the lives of queer Black women through a trans-temporal navigation of everyday encounters within familial, small groups and intimate partner spaces.

  17. A Hierarchical Causal Taxonomy of Psychopathology across the Life Span (United States)

    Lahey, Benjamin B.; Krueger, Robert F.; Rathouz, Paul J.; Waldman, Irwin D.; Zald, David H.


    We propose a taxonomy of psychopathology based on patterns of shared causal influences identified in a review of multivariate behavior genetic studies that distinguish genetic and environmental influences that are either common to multiple dimensions of psychopathology or unique to each dimension. At the phenotypic level, first-order dimensions are defined by correlations among symptoms; correlations among first-order dimensions similarly define higher-order domains (e.g., internalizing or externalizing psychopathology). We hypothesize that the robust phenotypic correlations among first-order dimensions reflect a hierarchy of increasingly specific etiologic influences. Some nonspecific etiologic factors increase risk for all first-order dimensions of psychopathology to varying degrees through a general factor of psychopathology. Other nonspecific etiologic factors increase risk only for all first-order dimensions within a more specific higher-order domain. Furthermore, each first-order dimension has its own unique causal influences. Genetic and environmental influences common to family members tend to be nonspecific, whereas environmental influences unique to each individual are more dimension-specific. We posit that these causal influences on psychopathology are moderated by sex and developmental processes. This causal taxonomy also provides a novel framework for understanding the heterogeneity of each first-order dimension: Different persons exhibiting similar symptoms may be influenced by different combinations of etiologic influences from each of the three levels of the etiologic hierarchy. Furthermore, we relate the proposed causal taxonomy to transdimensional psychobiological processes, which also impact the heterogeneity of each psychopathology dimension. This causal taxonomy implies the need for changes in strategies for studying the etiology, psychobiology, prevention, and treatment of psychopathology. PMID:28004947

    the ideas presented. It is evident that the genetic distances separating the sections are far from being of the same magnitude. The presumably older sections (Triseminatae, Trierectoides, Erectoides, Extranervosae and Heteranthae, except for section Erectoides, are much more isolated from the remaining sections and from each other than those taken to be of more recent origin (Procumbentes, Caulorrhizae, Rhizomatosae and Arachis. Section Arachis is by far the largest, containing about 40% of the species described. Species of this section appear to be spreading into new territory and to be invading areas occupied by species of other sections. They grow intermixed with populations of Extranervosae in the upper Paraguay basin and occupy common ground with section Procumbentes in the Gran Pantanal. They have reached the shores of La Plata and the southeastern coast of Brazil and grow from Yala in NW Argentina to the Tocantins in NE Brazil. They include the worldwide cultivar, A. hypogaea. Essentially every published work on the botanical history and taxonomy of Arachis is presented here in the individual specimen references and in the general bibliography. The history of A. hypogaeafrom the early 16th Century to more recent times, along with the common names in several native American languages, provide a perspective on the antiquity of this cultivar and the level of civilization required for its creation. Six appendices provide supporting data and matters of record. Diagnostic keys to the sections and to the species within each section select the more sharply distinguishing characteristics of the sections and species. Nineteen line drawings capture the sectional and species structures of whole plants, root systems, fruit orientations, agametic reproductions from fruiting structures, carpel shapes and surface features of leaves and stems.

    This study reviews a single institution experience with the Freedom SOLO (Sorin Group, Saluggia, Italy) aortic bioprosthesis. Between October 2006 and February 2010, 128 patients (64 men, 64 women; mean age, 75.8 ± 5.1 years) underwent aortic valve replacement using the Freedom SOLO stentless aortic valve. The follow-up time was 36.7 ± 1.2 months and 100% complete. Concomitant procedures were performed in 77 patients (60%). The mean standard European System for Cardiac Operative Risk Evaluation was 9 ± 2.7. Grade 3 aortic stenosis was present in 73% of patients, mixed aortic stenosis and regurgitation were present in 40% of patients, and mitral regurgitation was present in 46% of patients. The mean crossclamp time was 53 ± 12 minutes for isolated Freedom SOLO aortic valve implantation and 80 ± 28 minutes for concomitant procedures, and the mean cardiopulmonary bypass time was 103 ± 31 minutes. The mean implanted valve size was 22.6 ± 1.4 mm. The mean intensive care unit and hospital stays were 2.4 ± 1.1 days and 8.8 ± 2.6 days, respectively. Three patients underwent reoperation for bleeding. The 15-day, 30-day, and perioperative mortality were all 4.6%. The 36-month survival was 95.4% ± 1.6% for the cohort with a low European System for Cardiac Operative Risk Evaluation (9). Echocardiographic data preoperatively, immediately postoperatively, and at 3, 6, and 12 months postoperatively showed peak transvalvular gradients of 75 ± 23, 17 ± 6, 18 ± 6.5, 16 ± 6, and 16 ± 9 mm Hg, respectively (P SOLO stentless aortic valve has excellent early and intermediate-term results.

  1. Interplay between Solo and keratin filaments is crucial for mechanical force–induced stress fiber reinforcement (United States)

    Fujiwara, Sachiko; Ohashi, Kazumasa; Mashiko, Toshiya; Kondo, Hiroshi; Mizuno, Kensaku


    Mechanical force–induced cytoskeletal reorganization is essential for cell and tissue remodeling and homeostasis; however, the underlying cellular mechanisms remain elusive. Solo (ARHGEF40) is a RhoA-targeting guanine nucleotide exchange factor (GEF) involved in cyclical stretch–induced human endothelial cell reorientation and convergent extension cell movement in zebrafish gastrula. In this study, we show that Solo binds to keratin-8/keratin-18 (K8/K18) intermediate filaments through multiple sites. Solo overexpression promotes the formation of thick actin stress fibers and keratin bundles, whereas knockdown of Solo, expression of a GEF-inactive mutant of Solo, or inhibition of ROCK suppresses stress fiber formation and leads to disorganized keratin networks, indicating that the Solo-RhoA-ROCK pathway serves to precisely organize keratin networks, as well as to promote stress fibers. Of importance, knockdown of Solo or K18 or overexpression of GEF-inactive or deletion mutants of Solo suppresses tensile force–induced stress fiber reinforcement. Furthermore, knockdown of Solo or K18 suppresses tensile force-induced RhoA activation. These results strongly suggest that the interplay between Solo and K8/K18 filaments plays a crucial role in tensile force–induced RhoA activation and consequent actin cytoskeletal reinforcement.

  2. A taxonomy of dignity: a grounded theory study

    Directory of Open Access Journals (Sweden)

    Jacobson Nora


    Full Text Available Abstract Background This paper has its origins in Jonathan Mann's insight that the experience of dignity may explain the reciprocal relationships between health and human rights. It follows his call for a taxonomy of dignity: "a coherent vocabulary and framework to characterize dignity." Methods Grounded theory procedures were use to analyze literature pertaining to dignity and to conduct and analyze 64 semi-structured interviews with persons marginalized by their health or social status, individuals who provide health or social services to these populations, and people working in the field of health and human rights. Results The taxonomy presented identifies two main forms of dignity–human dignity and social dignity–and describes several elements of these forms, including the social processes that violate or promote them, the conditions under which such violations and promotions occur, the objects of violation and promotion, and the consequences of dignity violation. Together, these forms and elements point to a theory of dignity as a quality of individuals and collectives that is constituted through interaction and interpretation and structured by conditions pertaining to actors, relationships, settings, and the broader social order. Conclusion The taxonomy has several implications for work in health and human rights. It suggests a map to possible points of intervention and provides a language in which to talk about dignity.

  3. Thermophilic fungi in the new age of fungal taxonomy. (United States)

    de Oliveira, Tássio Brito; Gomes, Eleni; Rodrigues, Andre


    Thermophilic fungi are of wide interest due to their potential to produce heat-tolerant enzymes for biotechnological processes. However, the taxonomy of such organisms remains obscure, especially given new developments in the nomenclature of fungi. Here, we examine the taxonomy of the thermophilic fungi most commonly used in industry in light of the recent taxonomic changes following the adoption of the International Code of Nomenclature for Algae, Fungi and Plants and also based on the movement One Fungus = One Name. Despite the widespread use of these fungi in applied research, several thermotolerant fungi still remain classified as thermophiles. Furthermore, we found that while some thermophilic fungi have had their genomes sequenced, many taxa still do not have barcode sequences of reference strains available in public databases. This lack of basic information is a limiting factor for the species identification of thermophilic fungi and for metagenomic studies in this field. Based on next-generation sequencing, such studies generate large amounts of data, which may reveal new species of thermophilic fungi in different substrates (composting systems, geothermal areas, piles of plant material). As discussed in this study, there are intrinsic problems associated with this method, considering the actual state of the taxonomy of thermophilic fungi. To overcome such difficulties, the taxonomic classification of this group should move towards standardizing the commonly used species names in industry and to assess the possibility of including new systems for describing species based on environmental sequences.

  4. Quality control for terms and definitions in ontologies and taxonomies

    Directory of Open Access Journals (Sweden)

    Rüegg Alexander


    Full Text Available Abstract Background Ontologies and taxonomies are among the most important computational resources for molecular biology and bioinformatics. A series of recent papers has shown that the Gene Ontology (GO, the most prominent taxonomic resource in these fields, is marked by flaws of certain characteristic types, which flow from a failure to address basic ontological principles. As yet, no methods have been proposed which would allow ontology curators to pinpoint flawed terms or definitions in ontologies in a systematic way. Results We present computational methods that automatically identify terms and definitions which are defined in a circular or unintelligible way. We further demonstrate the potential of these methods by applying them to isolate a subset of 6001 problematic GO terms. By automatically aligning GO with other ontologies and taxonomies we were able to propose alternative synonyms and definitions for some of these problematic terms. This allows us to demonstrate that these other resources do not contain definitions superior to those supplied by GO. Conclusion Our methods provide reliable indications of the quality of terms and definitions in ontologies and taxonomies. Further, they are well suited to assist ontology curators in drawing their attention to those terms that are ill-defined. We have further shown the limitations of ontology mapping and alignment in assisting ontology curators in rectifying problems, thus pointing to the need for manual curation.

    Full Text Available RESUMO Foi avaliado o desempenho de práticas de drenagem superficial e cobertura morta em uma área de várzea do norte do Paraná. Antes e após o cultivo do arroz, foram comparadas as taxas de drenagem em tratamentos com e sem drenos torpedo e determinadas a vazão e a obstrução dos condutos. Sob o cultivo do feijoeiro, foram avaliados os efeitos dos drenos torpedo e de "camas" na drenagem e de cobertura morta (palha de arroz na retenção de água do solo. Os resultados indicaram que os drenos torpedo foram mais eficientes se construídos com solo menos úmido, porém sua longevidade foi menor que um ano. Sob o feijoeiro, os drenos torpedo e cobertura morta mantiveram o lençol freático mais profundo e o solo com menor tensão de umidade, mas esses efeitos ocorreram abaixo da zona radicular (15 cm, resultando em baixa produtividade.

  6. Pragmatic Strategies and Linguistic Structures in Making ‘Suggestions’: Towards Comprehensive Taxonomies

    Directory of Open Access Journals (Sweden)

    Hossein Abolfathiasl


    Full Text Available This paper analyses and upgrades taxonomies of strategies and structures for the speech act of suggesting based on existing taxonomies and classifications in the pragmatics research literature. Previous studies have focused mainly on linguistic structures used to perform the speech act of suggesting. Thus, there seems to be a need to provide a more comprehensive set of taxonomies for structures as well as strategies that can be used in EFL/ESL classrooms and for research on the speech act of suggesting. To this end, the speech act of suggesting is defined first and the features of this speech act are discussed. Second, the most recent classifications proposed for structures and linguistic realization strategies for suggestions were analysed and contrasted and a more comprehensive taxonomy of structures and linguistic realization strategies is provided, based on previous taxonomies. Finally, taxonomy of politeness strategies in making suggestions are provided, based on recent studies in cross-cultural pragmatics research.

    Full Text Available O preparo mecânico do solo é uma das práticas agrícolas que contribuem para o aumento da perda de carbono via emissão de CO2 do solo (FCO2. Com este trabalho objetivou-se investigar o efeito de três sistemas de preparo do solo na FCO2, temperatura e umidade do solo em área de reforma da cultura de cana-de-açúcar. A área experimental foi constituída de três parcelas, cada uma recebendo um dos preparos do solo: preparo convencional (PC, subsolagem convencional (SC e subsolagem localizada (SL. A FCO2, temperatura e a umidade do solo foram avaliadas durante o período total de 17 dias. A FCO2 foi maior no preparo PC (0,75 g CO2 m-2 h-1. A temperatura do solo não diferiu (p > 0,05 entre as subsolagens: SL (26,2 ºC e SC (25,9 ºC. A umidade do solo foi maior na SL (24%, seguida pela SC (21,8% e preparo PC (18,3%. Apenas no preparo PC foi observada correlação significativa (r = –0,71; p < 0,05 entre FCO2 e a temperatura do solo. O preparo PC apresentou emissão total (2.864,3 kg CO2 ha-1, superior às emissões nas subsolagens: SC (1.970,9 kg CO2 ha-1 e SL (1.707,7 kg CO2 ha-1. A conversão do sistema de preparo PC para a SL diminuiu as emissões de CO2 do solo, reduzindo a contribuição da agricultura para o aumento dos gases de efeito estufa na atmosfera.

    Microbial taxonomy should provide adequate descriptions of bacterial, archaeal, and eukaryotic microbial diversity in ecological, clinical, and industrial environments. We re-evaluated the prokaryote species twice. It is time to revisit polyphasic taxonomy, its principles, and its practice, including its underlying pragmatic species concept. We will be able to realize an old dream of our predecessor taxonomists and build a genomic-based microbial taxonomy, using standardized and automated curation of high-quality complete genome sequences as the new gold standard.

    Jonathan Willian Zangeski Novais


    Full Text Available Resumo Este artigo analisou o albedo do solosolo abaixo do dossel considerando duas etapas no ciclo hidrológico, a primeira em que o solo estava inundado e a segunda em que o solo estava coberto por serrapilheira acumulada sobre o solo em área inundável de Vochysia divergens Pohl no Pantanal, Brasil. Os valores de αsolo foram calculados pela relação entre as radiação solar global refletida e a incidente medidas abaixo do dossel por meio de estações meteorológicas. A inundação da área ocorreu durante fevereiro a junho e posteriormente houve um aumento gradativo de serrapilheira acumulada sobre o solo. O αsolo variou sazonalmente com maiores valores durante o período seco em que houve um aumento de aproximadamente 42% do αsolo em relação ao período com inundação. Análises de correlação cruzada entre o αsolo e precipitação, umidade do solo e a serrapilheira acumulada sobre o solo explicam em parte a influência direta e/ou indireta sobre o αsolo. A precipitação não influenciou diretamente sobre o αsolo do mês atual, enquanto que a umidade do solo influenciou diretamente sobre o αsolo no mês atual e nos seguintes meses, e a serrapilheira acumulada do solo correlacionou-se positivamente com o αsolo indicando influência direta no mês atual.

    Full Text Available A degradação do solo no semiárido também ocorre pelo desmatamento da Caatinga e pela remoção da camada superficial do solo, cujo destino é a indústria de cerâmica ou olarias. O presente trabalho objetivou avaliar o crescimento da mamoneira em solos degradados. Os tratamentos consistiram de solos degradados: subsolo degradado-1, subsolo degradado-2 e área desmatada; quatro doses de fósforo (0, 100, 200, 300 mgkg-1 P, com três repetições. As testemunhas absolutas, sem fósforo, corresponderam ao solo salinizado não corrigido, solo-1 não degradado, solo-2 não degradado e solo de caatinga não desmatada. O solo degradado por sais, o subsolo-2, recebeu correção com gesso agrícola, foi incubado e lavado. Os resultados demonstraram que a análise do subsolo degradado revelou alta salinidade e baixos teores de fósforo e matéria orgânica, o subsolo degradado salino exige correção com gesso para tornar possível o cultivo da mamona em caatinga desmatada e subsolos degradados. As doses de fósforo não promoveram desenvolvimento significativo em mudas de mamona.

    Gustavo Giménez


    Full Text Available O morangueiro é uma cultura importante em vários países, principalmente nos Estados Unidos e na Europa, por suas características sensoriais, propriedades nutritivas e por sua rentabilidade. O cultivo comercial sem solo de morangueiro está bem desenvolvido na Europa, onde tem permitido um aumento da produtividade e qualidade da produção assim como a ampliação da oferta do produto ao longo do ano. Predomina o sistema aberto, em sacolas ou vasos com diferentes tipos de substratos, utilizando-se densidades de 8 a 12plantas m-2. As produtividades obtidas estão entre 5 e 10kg m-2. Para isolar as plantas do solo e facilitar o manejo da cultura, os vasos ou sacolas são suspensos a uma altura entre 0,8 e 1m da superfície do solo. A composição da solução nutritiva é variável, refletindo as diferentes condições produtivas. As mudas são produzidas principalmente em bandejas com substrato, a partir de pontas de estolões obtidas da multiplicação de plantas matrizes provenientes da propagação in vitro. No Brasil, o cultivo sem solo de morangueiro é ainda incipiente e os resultados produtivos e econômicos têm sido insatisfatórios, principalmente por falta de informações de pesquisas capazes de indicar sistemas apropriados de cultivo para as condições locais. É necessário desenvolver sistemas sustentáveis, preferencialmente fechados, combinando alta produtividade e elevada eficiência de utilização da água e dos nutrientes. No presente trabalho, são revisados os principais aspectos da produção em sistemas de cultivo sem solo de mudas e fruta de morangueiro. São descritos a produção de mudas, os sistemas e as soluções nutritivas empregadas em diferentes países. Ao final, são feitas inferências sobre a possibilidade de adoção e geração do sistema de cultivo sem solo apropriado para as condições brasileiras.Strawberry is a very important crop in Europe and USA due to its nutritional and sensorial

    P.J. Christoffoleti


    Full Text Available The goal of this literature review is to discuss some of the major aspects of the soil seed bank, from its characteristics down to methodological aspects of its determination. Soil seed bank is the reservoir of viable seeds or of vegetative propagules that are present in the soil and that are able to recompose a natural vegetation. In the agroecossystems the soil seed bank is related to weeds, and the knowledge of its size and composition in terms of species can be used in the prediction of future infestations, to built simulation models of population establishment through time and also the definition of soil and cultural management programs, in order to have a rational use of herbicides.O objetivo desta revisão é discorrer sobre alguns pontos importantes no estudo do banco de sementes no solo, desde as sua características até aspectos metodológicos para sua determinação. Denomina-se de banco de sementes a reserva destas ou de propágulos vegetativos viáveis presentes no solo e que são capazes de recompor uma vegetação. Nos sistemas agrícolas o banco está relacionado com o estudo das plantas daninhas; o conhecimento do seu tamanho e das espécies que o compõem poderá ser utilizado na previsão de infestações futuras, na construção de modelos de estabelecimentos populacionais no tempo e consequentemente na definição de programas de manejo de solo e culturais, visando racionalizar a utilização de herbicidas.

  14. Fast reactor knowledge preservation system: Taxonomy and basic requirements

    International Nuclear Information System (INIS)


    The IAEA has taken the initiative to coordinate efforts of Member States in the preservation of knowledge in the area of fast reactors. In the framework of this initiative, the IAEA intends to create an international database compiling information from different Member States on fast reactors through a web portal. Other activities related to this initiative are being designed to accumulate and exchange information on the fast reactor area, to facilitate access to this information by users in different countries and to assist Member States in preserving the experience gained in their countries. The purpose of this publication is to develop a taxonomy of the Fast Reactor Knowledge Preservation System (FRKPS) that will facilitate the preservation of the world's fast reactor knowledge base, to identify basic requirements of this taxonomy on the basis of the experience gained in the fast reactor area, as well as results of previous IAEA activities on fast reactor knowledge preservation. The need for such taxonomy arises from the fact that during the past 15 years there has been stagnation in the development of fast reactors in the industrialized countries that were involved, earlier, in intensive development of this area. All studies on fast reactors have been stopped in countries such as Germany, Italy, the United Kingdom and the United States of America and the only work being carried out is related to the decommissioning of fast reactors. Many specialists who were involved in the studies and development work in this area in these countries have already retired or are close to retirement. In countries such as France, Japan and the Russian Federation that are still actively pursuing the evolution of fast reactor technology, the situation is aggravated by the lack of young scientists and engineers moving into this branch of nuclear power

  15. Análise de componentes principais de atributos físicos, químicos e mineralógicos de solos do bioma cerrado Principal component analysis of physical, chemical, and mineralogical attributes of the cerrado biome soils

    Directory of Open Access Journals (Sweden)

    J. B. V. Gomes


    Full Text Available Com o intuito de avaliar diferenças de comportamento entre solos das superfícies geomórficas Sul-Americana e Velhas da região dos Cerrados, todos sob uso atual de cobertura vegetal nativa, foram realizadas caracterizações físicas, químicas e mineralógicas, bem como feitas análises de componentes principais desses atributos. Com os solos referenciados por sub-região e pela superfície geomórfica que representam, três agrupamentos foram constituídos: Grupo 1: solos de textura argilosa a muito argilosa e hipo a mesoférricos; Grupo 2: solos de textura média a arenosa e hipoférricos; e Grupo 3: solos de textura argilosa a muito argilosa e férricos. A retenção de água dos horizontes superficiais dos solos estudados foi positivamente correlacionada com os teores de argila e carbono orgânico. Os solos do Grupo 3 apresentaram a maior oferta de bases trocáveis dos horizontes superficiais, o que foi relacionado, em grande parte, com a maior reciclagem imposta pela formação florestal local, quando comparada à da formação de cerrado, presente em 31 dos 33 perfis de solos dos Grupos 1 e 2. O Grupo 3, diferenciado pelos elevados teores de Fe herdados do material de origem, é o grupo mais homogêneo em termos mineralógicos, com todos os perfis hematíticos. Os Grupos 1 e 2 apresentam sobreposição de composição mineralógica, sendo o Grupo 1, em termos médios, mais gibbsítico do que o Grupo 2. A maior eficácia do Sistema Brasileiro de Classificação de Solos, relativamente ao Soil Taxonomy, em discriminar os solos estudados é resultante do uso do caráter férrico concomitantemente a outros atributos comuns aos dois sistemas. A análise de componentes principais auxiliou no entendimento das diferenças e similaridades dos ambientes pedológicos separados no campo.Behavior differences between soils of the South-American and Velhas geomorphic surfaces of the Cerrado region, all of them under native vegetation cover, were

    Full Text Available A análise ambiental, com base nos processos de morfogênese e pedogênese, possibilita informações importantes para a elaboração de políticas públicas visando o uso e ocupação da paisagem de maneira sustentável. Com isso, objetivou-se identificar os diferentes níveis de vulnerabilidade natural à perda de solo do município de Silveira Martins, RS. Foi elaborado um banco de dados espaciais em um ambiente de Sistemas de Informações Geográficas (SIG com auxílio do software Spring. O zoneamento da vulnerabilidade natural à perda de solo foi elaborado com base nas informações referentes à declividade, geomorfologia, geologia e solos de acordo com o grau de vulnerabilidade de cada informação, por meio da álgebra de mapas. Para o território municipal de Silveira Martins identificou-se a ocorrência de cinco classes. Destacam-se as unidades estáveis com predomínio dos processos formadores do solo (38,08% da área municipal, e as unidades moderadamente vulneráveis, prevalecendo os processos erosivos (53,67%. As áreas classificadas como moderadamente vulnerável e vulnerável (8,25%, correspondem a áreas com inclinações superiores a 25º e com formação geológica e geomorfológica menos estáveis. Nas unidades em que predominou a vulnerabilidade natural, sugere-se especial atenção em relação ao meio natural e aos agentes que o influenciam, visando boas práticas sociais associadas às políticas ambientais no processo de tomada de decisões econômicas, possibilitando a valorização e proteção do meio natural.

  17. Penetration Testing Professional Ethics: a conceptual model and taxonomy

    Directory of Open Access Journals (Sweden)

    Justin Pierce


    Full Text Available In an environment where commercial software is continually patched to correct security flaws, penetration testing can provide organisations with a realistic assessment of their security posture. Penetration testing uses the same principles as criminal hackers to penetrate corporate networks and thereby verify the presence of software vulnerabilities. Network administrators can use the results of a penetration test to correct flaws and improve overall security. The use of hacking techniques, however, raises several ethical questions that centre on the integrity of the tester to maintain professional distance and uphold the profession. This paper discusses the ethics of penetration testing and presents our conceptual model and revised taxonomy.

    Bzura, Conrad; Im, Hosung; Liu, Tammy; Malehorn, Kevin; Padir, Taskin; Tulu, Bengisu


    This paper evaluates existing taxonomies aimed at characterizing the interaction between robots and their users and modifies them for health care applications. The modifications are based on existing robot technologies and user acceptance of robotics. Characterization of the user, or in this case the patient, is a primary focus of the paper, as they present a unique new role as robot users. While therapeutic and monitoring-related applications for robots are still relatively uncommon, we believe they will begin to grow and thus it is important that the spurring relationship between robot and patient is well understood.

  1. Taxonomy of interstate conflicts: is South America a peaceful region?

    Directory of Open Access Journals (Sweden)

    Tássio Franchi


    Full Text Available This article revisits theoretical efforts to classify interstate conflicts. It analyses South America and discuss the adequacy of influential interpretations about the intensity of interstate conflicts in the region as compared to global or other regions ones. The literature takes for granted that South America is a peaceful region. Such interpretation results from the indicators adopted. We argue that traditional indicators do not fully capture latent tensions and the actual level of conflicts in the region. The article suggests an alternative taxonomy that better fits the South America context and argues that a research agenda on the extent and nature of interstate conflics is needed.

  6. Developing a taxonomy of coordination behaviours in nuclear power plant control rooms during emergencies. (United States)

    Wang, Dunxing; Gao, Qin; Li, Zhizhong; Song, Fei; Ma, Liang


    This study aims to develop a taxonomy of coordination behaviours during emergencies in nuclear power plants (NPPs). We summarised basic coordination behaviours from literature in aviation, health care and nuclear field and identified coordination behaviours specific to the nuclear domain by interviewing and surveying control crew operators. The established taxonomy includes 7 workflow stages and 24 basic coordination behaviours. To evaluate the reliability and feasibility of the taxonomy, we analysed 12 videos of operators' training sessions by coding coordination behaviours with the taxonomy and the inter-rater reliability was acceptable. Further analysis of the frequency, the duration and the direction of the coordination behaviours revealed four coordination problems. This taxonomy provides a foundation of systematic observation of coordination behaviours among NPP crews, advances researchers' understanding of the coordination mechanism during emergencies in NPPs and facilitate the possibility to deepen the understanding of the relationships between coordination behaviours and team performance. Practitioner Summary: A taxonomy of coordination behaviours during emergencies in nuclear power plants was developed. Reliability and feasibility of the taxonomy was verified through the analysis of 12 training sessions. The taxonomy can serve as an observation system for analysis of coordination behaviours and help to identify coordination problems of control crews.

  8. Taxonomy for Education and Training in Clinical Neuropsychology: past, present, and future. (United States)

    Sperling, Scott A; Cimino, Cynthia R; Stricker, Nikki H; Heffelfinger, Amy K; Gess, Jennifer L; Osborn, Katie E; Roper, Brad L


    Historically, the clinical neuropsychology training community has not clearly or consistently defined education or training opportunities. The lack of consistency has limited students' and trainees' ability to accurately assess and compare the intensity of neuropsychology-specific training provided by programs. To address these issues and produce greater 'truth in advertising' across programs, CNS, with SCN's Education Advisory Committee (EAC), ADECN, AITCN, and APPCN constructed a specialty-specific taxonomy, namely, the Taxonomy for Education and Training in Clinical Neuropsychology. The taxonomy provides consensus in the description of training offered by doctoral, internship, and postdoctoral programs, as well as at the post-licensure stage. Although the CNS approved the taxonomy in February 2015, many programs have not adopted its language. Increased awareness of the taxonomy and the reasons behind its development and structure, as well as its potential benefits, are warranted. In 2016, a working group of clinical neuropsychologists from the EAC and APPCN, all authors of this manuscript, was created and tasked with disseminating information about the taxonomy. Group members held regular conference calls, leading to the generation of this manuscript. This manuscript is the primary byproduct of the working group. Its purpose is to (1) outline the history behind the development of the taxonomy, (2) detail its structure and utility, (3) address the expected impact of its adoption, and (4) call for its adoption across training programs. This manuscript outlines the development and structure of the clinical neuropsychology taxonomy and addresses the need for its adoption across training programs.

  13. Adaptability in the workplace: development of a taxonomy of adaptive performance. (United States)

    Pulakos, E D; Arad, S; Donovan, M A; Plamondon, K E


    The purpose of this research was to develop a taxonomy of adaptive job performance and examine the implications of this taxonomy for understanding, predicting, and training adaptive behavior in work settings. Two studies were conducted to address this issue. In Study 1, over 1,000 critical incidents from 21 different jobs were content analyzed to identify an 8-dimension taxonomy of adaptive performance. Study 2 reports the development and administration of an instrument, the Job Adaptability Inventory, that was used to empirically examine the proposed taxonomy in 24 different jobs. Exploratory factor analyses using data from 1,619 respondents supported the proposed 8-dimension taxonomy from Study 1. Subsequent confirmatory factor analyses on the remainder of the sample (n = 1,715) indicated a good fit for the 8-factor model. Results and implications are discussed.

    Pradoto, W.; Mardiansjah, F. H.; Manullang, O. R.; Putra, A. A.


    Dynamic urbanization in Solo Raya, a local term for Surakarta Metropolitan, amongst rapid regional based-urbanization in Indonesia, shows the unbalance pattern of growth. A number of Surakarta City’s peripherals become the newly growing area which is characterized by a well-facilitated region, while the former urbanized areas next to the city center present the declining process. Different socioeconomic development triggers a unique mosaic of socio-spatial pattern, on which the phenomena of peripheralization could be investigated. Urban investment that boosted by the political will of both the national and local government has led to a shift in demographic condition. A relatively massive in-migration has been attracted to the peripheral and creates the new landscape of urban-rural society. Complex dynamic of metropolitan growth and the resulting peripheralization reminds that socio-spatial pattern calls the challenges for managing the rapid change of land use and space use. The pattern of urbanization that differs upon the surrounding areas of Surakarta City would be interesting to be explored. This paper will discuss the conceptual framework of peripheral urbanization and the methodological approach. It is actually the part of ongoing research on peripheralisation in Solo Raya.

  15. Toward A Unifying Taxonomy and Definition for Meditation

    Jonathan David Nash


    Full Text Available One of the well-documented concerns confronting scholarly discourse about meditation is the plethora of semantic constructs and the lack of a unified definition and taxonomy. In recent years there have been several notable attempts to formulate new lexicons in order to define and categorize meditation methods. While these constructs have been useful and have encountered varying degrees of acceptance, they have also been subject to misinterpretation and debate, leaving the field devoid of a consensual paradigm. This paper attempts to influence this ongoing discussion by proposing two new models which hold the potential for enhanced scientific reliability and acceptance. Regarding the quest for a universally acceptable taxonomy, we suggest a paradigm shift away from the fabrication of categories based exclusively on first-person perspectives. As an alternative, we propose a new taxonomic system based on a third-person paradigm borrowed, in part, from the psychological and cognitive sciences. With regard to the elusive definitional problem, we propose a model of meditation as a dynamic process composed of several related but distinct stages. The overall goal is to provide researchers with a reliable nomenclature with which to categorize and classify diverse meditation methods, and a conceptual framework which can provide direction for their research and a theoretical basis for their findings.

  16. Threat and error management for anesthesiologists: a predictive risk taxonomy (United States)

    Ruskin, Keith J.; Stiegler, Marjorie P.; Park, Kellie; Guffey, Patrick; Kurup, Viji; Chidester, Thomas


    Purpose of review Patient care in the operating room is a dynamic interaction that requires cooperation among team members and reliance upon sophisticated technology. Most human factors research in medicine has been focused on analyzing errors and implementing system-wide changes to prevent them from recurring. We describe a set of techniques that has been used successfully by the aviation industry to analyze errors and adverse events and explain how these techniques can be applied to patient care. Recent findings Threat and error management (TEM) describes adverse events in terms of risks or challenges that are present in an operational environment (threats) and the actions of specific personnel that potentiate or exacerbate those threats (errors). TEM is a technique widely used in aviation, and can be adapted for the use in a medical setting to predict high-risk situations and prevent errors in the perioperative period. A threat taxonomy is a novel way of classifying and predicting the hazards that can occur in the operating room. TEM can be used to identify error-producing situations, analyze adverse events, and design training scenarios. Summary TEM offers a multifaceted strategy for identifying hazards, reducing errors, and training physicians. A threat taxonomy may improve analysis of critical events with subsequent development of specific interventions, and may also serve as a framework for training programs in risk mitigation.

    Velankar, Sameer; Dana, José M.; Jacobsen, Julius; van Ginkel, Glen; Gane, Paul J.; Luo, Jie; Oldfield, Thomas J.; O’Donovan, Claire; Martin, Maria-Jesus; Kleywegt, Gerard J.


    The Structure Integration with Function, Taxonomy and Sequences resource (SIFTS; is a close collaboration between the Protein Data Bank in Europe (PDBe) and UniProt. The two teams have developed a semi-automated process for maintaining up-to-date cross-reference information to UniProt entries, for all protein chains in the PDB entries present in the UniProt database. This process is carried out for every weekly PDB release and the information is stored in the SIFTS database. The SIFTS process includes cross-references to other biological resources such as Pfam, SCOP, CATH, GO, InterPro and the NCBI taxonomy database. The information is exported in XML format, one file for each PDB entry, and is made available by FTP. Many bioinformatics resources use SIFTS data to obtain cross-references between the PDB and other biological databases so as to provide their users with up-to-date information. PMID:23203869

  18. Taxonomy of Rhagoletis population associated with wild plums in Chile

    International Nuclear Information System (INIS)

    Frias, Daniel; Alvina, Andres


    In South America, there are about fifteen Rhagoletis species that live in association with wild and cultivated Solanaceae host plants (Foote 1981, Frias 1992). The principal information on taxonomy for these species is the morphology of adults. Thus, in the genus Rhagoletis, in general, there is little information about immature stages especially on first and second larva instars (Steck et al. 1990, Carrol and Wharton 1989, Steck and Wharton 1988, Persson 1963, White and Elson-Harris 1992, Hernandez-Ortiz 1992, 1993, Frias et al. 1993). Presently, in Chile, there are 4 species associated with Solanaceae host plants. R. tomatis Foote and R. nova (Schiner) are associated with cultivated Solanaceae Lycopersicum esculentum Miller or cultivated tomatoes and Solanum muricatum Aiton or sweet cucumber respectively. R. conversa Bethes has two Solanum host plants, S. nigrum L. and S. tomatillo (Remy) Phil. F. (Frias et al. 1984). The host for R. penela Foote is unknown. Moreover, in the last few years, a population on wild plums of the Myrobalan variety (Rosaceae) was detected (Gonzalez 1989). At present, there is no information about the origin and taxonomy of this population. In this work, we have studied the morphology of eggs, three instar larvae, pupae and adults of this population associated with wild plums as well as aspects of its geographical distribution in Chile

  19. Constructing Taxonomies to Identify Distinctive Forms of Primary Healthcare Organizations (United States)

    Borgès Da Silva, Roxane; Pineault, Raynald; Hamel, Marjolaine; Levesque, Jean-Frédéric; Roberge, Danièle; Lamarche, Paul


    Background. Primary healthcare (PHC) renewal gives rise to important challenges for policy makers, managers, and researchers in most countries. Evaluating new emerging forms of organizations is therefore of prime importance in assessing the impact of these policies. This paper presents a set of methods related to the configurational approach and an organizational taxonomy derived from our analysis. Methods. In 2005, we carried out a study on PHC in two health and social services regions of Quebec that included urban, suburban, and rural areas. An organizational survey was conducted in 473 PHC practices. We used multidimensional nonparametric statistical methods, namely, multiple correspondence and principal component analyses, and an ascending hierarchical classification method to construct a taxonomy of organizations. Results. PHC organizations were classified into five distinct models: four professional and one community. Study findings indicate that the professional integrated coordination and the community model have great potential for organizational development since they are closest to the ideal type promoted by current reforms. Conclusion. Results showed that the configurational approach is useful to assess complex phenomena such as the organization of PHC. The analysis highlights the most promising organizational models. Our study enhances our understanding of organizational change in health services organizations. PMID:24959575

  20. Toward a unifying taxonomy and definition for meditation (United States)

    Nash, Jonathan D.; Newberg, Andrew


    One of the well-documented concerns confronting scholarly discourse about meditation is the plethora of semantic constructs and the lack of a unified definition and taxonomy. In recent years there have been several notable attempts to formulate new lexicons in order to define and categorize meditation methods. While these constructs have been useful and have encountered varying degrees of acceptance, they have also been subject to misinterpretation and debate, leaving the field devoid of a consensual paradigm. This paper attempts to influence this ongoing discussion by proposing two new models which hold the potential for enhanced scientific reliability and acceptance. Regarding the quest for a universally acceptable taxonomy, we suggest a paradigm shift away from the norm of fabricatIng new terminology from a first-person perspective. As an alternative, we propose a new taxonomic system based on the historically well-established and commonly accepted third-person paradigm of Affect and Cognition, borrowed, in part, from the psychological and cognitive sciences. With regard to the elusive definitional problem, we propose a model of meditation which clearly distinguishes “method” from “state” and is conceptualized as a dynamic process which is inclusive of six related but distinct stages. The overall goal is to provide researchers with a reliable nomenclature with which to categorize and classify diverse meditation methods, and a conceptual framework which can provide direction for their research and a theoretical basis for their findings.

  1. The past, the present and the future of eutardigrade taxonomy

    Directory of Open Access Journals (Sweden)

    Giovanni Pilato


    Full Text Available The Author first recalls the past of eutardigrade taxonomy and indicates the main factors that for a long time restrained its progress. One consequence of a superficial analysis is that very wide individual variability has been erroneously attributed to many species, and this has become the main problem for tardigrade taxonomists. The situation began to change after 1969 because of the first attempts to eliminate the above mentioned problems. Novelties gave impetus to the revision of tardigrade taxonomy, and genuine systematics, finally based on phylogenetics, became popular. Today the morphological characters are considered more in depth and studies utilising DNA sequences are more in fashion; they are surely useful and allow the distinction of morphologically very similar species. However, in the author’s opinion, this progress will be possible only if the molecular studies are always associated with careful morphological studies, which, in the meantime, will be more and more detailed also thanks to the use of the Scanning Electron Microscopy (SEM.

  2. Building a Framework for a Dual Task Taxonomy

    Directory of Open Access Journals (Sweden)

    Tara L. McIsaac


    Full Text Available The study of dual task interference has gained increasing attention in the literature for the past 35 years, with six MEDLINE citations in 1979 growing to 351 citations indexed in 2014 and a peak of 454 cited papers in 2013. Increasingly, researchers are examining dual task cost in individuals with pathology, including those with neurodegenerative diseases. While the influence of these papers has extended from the laboratory to the clinic, the field has evolved without clear definitions of commonly used terms and with extreme variations in experimental procedures. As a result, it is difficult to examine the interference literature as a single body of work. In this paper we present a new taxonomy for classifying cognitive-motor and motor-motor interference within the study of dual task behaviors that connects traditional concepts of learning and principles of motor control with current issues of multitasking analysis. As a first step in the process we provide an operational definition of dual task, distinguishing it from a complex single task. We present this new taxonomy, inclusive of both cognitive and motor modalities, as a working model; one that we hope will generate discussion and create a framework from which one can view previous studies and develop questions of interest.

  3. A taxonomy of accountable care organizations for policy and practice. (United States)

    Shortell, Stephen M; Wu, Frances M; Lewis, Valerie A; Colla, Carrie H; Fisher, Elliott S


    To develop an exploratory taxonomy of Accountable Care Organizations (ACOs) to describe and understand early ACO development and to provide a basis for technical assistance and future evaluation of performance. Data from the National Survey of Accountable Care Organizations, fielded between October 2012 and May 2013, of 173 Medicare, Medicaid, and commercial payer ACOs. Drawing on resource dependence and institutional theory, we develop measures of eight attributes of ACOs such as size, scope of services offered, and the use of performance accountability mechanisms. Data are analyzed using a two-step cluster analysis approach that accounts for both continuous and categorical data. We identified a reliable and internally valid three-cluster solution: larger, integrated systems that offer a broad scope of services and frequently include one or more postacute facilities; smaller, physician-led practices, centered in primary care, and that possess a relatively high degree of physician performance management; and moderately sized, joint hospital-physician and coalition-led groups that offer a moderately broad scope of services with some involvement of postacute facilities. ACOs can be characterized into three distinct clusters. The taxonomy provides a framework for assessing performance, for targeting technical assistance, and for diagnosing potential antitrust violations. © Health Research and Educational Trust.

  4. A refined taxonomy of behaviour change techniques to help people change their physical activity and healthy eating behaviours: the CALO-RE taxonomy. (United States)

    Michie, Susan; Ashford, Stefanie; Sniehotta, Falko F; Dombrowski, Stephan U; Bishop, Alex; French, David P


    Current reporting of intervention content in published research articles and protocols is generally poor, with great diversity of terminology, resulting in low replicability. This study aimed to extend the scope and improve the reliability of a 26-item taxonomy of behaviour change techniques developed by Abraham and Michie [Abraham, C. and Michie, S. (2008). A taxonomy of behaviour change techniques used in interventions. Health Psychology, 27(3), 379-387.] in order to optimise the reporting and scientific study of behaviour change interventions. Three UK study centres collaborated in applying this existing taxonomy to two systematic reviews of interventions to increase physical activity and healthy eating. The taxonomy was refined in iterative steps of (1) coding intervention descriptions, and assessing inter-rater reliability, (2) identifying gaps and problems across study centres and (3) refining the labels and definitions based on consensus discussions. Labels and definitions were improved for all techniques, conceptual overlap between categories was resolved, some categories were split and 14 techniques were added, resulting in a 40-item taxonomy. Inter-rater reliability, assessed on 50 published intervention descriptions, was good (kappa = 0.79). This taxonomy can be used to improve the specification of interventions in published reports, thus improving replication, implementation and evidence syntheses. This will strengthen the scientific study of behaviour change and intervention development.

    The incidence of postoperative thrombocytopenia after aortic valve replacement with the Freedom Solo bioprosthesis remains unclear. This propensity-matched study was carried out to evaluate the incidence and clinical impact of thrombocytopenia in patients receiving the Freedom Solo bioprosthesis. Patients who underwent aortic valve replacement with a Freedom Solo or Carpentier-Edwards Perimount pericardial prosthesis at our institution between 2006 and 2008 were screened retrospectively. Exclusion criteria included double valve replacement, redo surgery, and active endocarditis. Two hundred six patients were considered eligible for this analysis. Using propensity scores 36 matched pairs of patients with a Freedom Solo or Perimount bioprosthesis were obtained. The primary end point was the occurrence of postoperative thrombocytopenia. Secondary end points were postoperative thromboembolic or hemorrhagic events and 30-day mortality. Before matching, severe thrombocytopenia (Solo bioprosthesis and 1% with a Perimount bioprosthesis (p Solo (p Solo and Perimount bioprostheses, respectively (p Solo implantation.

    Full Text Available Os solos do Estado da Paraíba apresentam grande diversidade de características químicas, físicas e mineralógicas, acarretando em variações nos teores e formas de K disponíveis no solo. Objetivou-se com este trabalho avaliar os teores de K não-trocável, K trocável e K solúvel em doze solos do Estado da Paraíba, na ausência e na presença de fertilização potássica, e correlacioná-los com as características químicas, físicas e mineralógicas desses solos. O estudo constou de 60 tratamentos, sendo 12 solos e cinco doses de K (0; 50; 100; 200 e 300 mg dm-3 na forma de cloreto de potássio, com três repetições. Após receberem os tratamentos, os solos foram incubados por um período de 21 dias, e em seguida, uma sub-amostra de 0,2 dm³ de cada solo foi retirada para determinação dos teores de K não-trocável, K trocável e K solúvel. Os solos formados sob clima semiárido foram os solos que apresentaram as maiores reservas de K não-trocável. Solos com maior proporção de mica e minerais do tipo 2:1 na fração argila apresentaram os maiores teores de K não-trocável e K trocável. Independente do grupo de solos, os teores de silte apresentaram correlação elevada com os teores de K não-trocável e de K trocável. Nos solos mais desenvolvidos, não foi evidenciada fixação de K proveniente do fertilizante. Porém, nos solos menos desenvolvidos, a fixação de K ficou evidenciada pela pequena quantidade de K recuperada pelo extrator acetato de amônio nos solos mais argilosos e, principalmente, naqueles com predominância de minerais do tipo 2:1 e mica.

  12. A 76-year old man with a torn Freedom SOLO bioprosthesis. (United States)

    Wollersheim, Laurens W; Li, Wilson W; van der Meulen, Jan; de Mol, Bas A


    We describe a case of a 76-year old male who presented with progressive dyspnoea. He underwent an aortic valve replacement with a Freedom SOLO bioprosthesis 6 years ago. Transthoracic echocardiography showed a moderate-to-severe leakage of the Freedom SOLO bioprosthesis. During surgical reintervention, a partial tear of the left coronary cusp was seen from the commissure of the right coronary cusp to its base. After radiographic and microscopic examination, no clear cause was found for the failure of this Freedom SOLO bioprosthesis. To our knowledge, this is the third failure of a Freedom SOLO bioprosthesis reported in the literature. When the long-term follow-up of the Freedom SOLO bioprosthesis is available, it has to be compared with other bioprosthesis for long-term durability.

  13. African-American Solo Grandparents Raising Grandchildren: A Representative Profile of Their Health Status. (United States)

    Whitley, Deborah M; Fuller-Thomson, Esme


    The objective of this study is to document the health profile of 252 African-American grandparents raising their grandchildren solo, compared with 1552 African-American single parents. The 2012 Behavior Risk Factor Surveillance System is used to compare the specific physical and mental health profiles of these two family groups. The findings suggest solo grandparents have prevalence of many health conditions, including arthritis (50.3 %), diabetes (20.1 %), heart attack (16.6 %) and coronary heart disease (16.6 %). Logistic regression analyses suggest that solo grandparents have much higher odds of several chronic health disorders in comparison with single parents, but this difference is largely explained by age. Although solo grandparents have good access to health care insurance and primary care providers, a substantial percentage (44 %) rate their health as fair or poor. Practice interventions to address African American solo grandparents' health needs are discussed.

  14. Feasibility of four-arm robotic lobectomy as solo surgery in patients with clinical stage I lung cancer. (United States)

    Park, Seong Yong; Suh, Jee Won; Narm, Kyoung Sik; Lee, Chang Young; Lee, Jin Gu; Paik, Hyo Chae; Chung, Kyoung Young; Kim, Dae Joon


    This study was performed to investigate the feasibility of four-arm robotic lobectomy (FARL) as a solo surgical technique in patients with non-small cell lung cancer (NSCLC). Early outcome and long-term survival of FARL were compared with those of video-assisted thoracoscopic lobectomy (VATL). Prospective enrollment of patients with clinical stage I NSCLC undergoing FARL or VATL (20 patients in each group) was planned. Interim analysis for early postoperative outcome was performed after the initial 10 cases in each group. The study was terminated early because of safety issues in the FARL group after enrollment of 12 FARL and 17 VATL patients from 2011 to 2012. There were no differences in clinical characteristics between groups. Lobectomy time and total operation time were significantly longer in the FARL group (P=0.003). There were three life-threatening events in the FARL group (2 bleedings, 1 bronchus tear) that necessitated thoracotomy conversion in 1 patient. There were no differences in other operative outcomes including pain score, complications, or length of hospital stay. Pathologic stage and number of dissected lymph nodes (LNs) were also comparable. During a follow-up of 48.9±9.5 months, recurrence was identified in 2 (16.7%) patients in FARL group and 3 (23.5%) in VATL group. Five-year overall survival (100% vs . 87.5%, P=0.386) and disease-free survival (82.5% vs . 75.6%, P=0.589) were comparable. FARL as solo surgery could not be recommended because of safety issues. It required a longer operation time and had no benefits over VATL in terms of early postoperative outcome or long-term survival.

  15. Interplay between Solo and keratin filaments is crucial for mechanical force-induced stress fiber reinforcement. (United States)

    Fujiwara, Sachiko; Ohashi, Kazumasa; Mashiko, Toshiya; Kondo, Hiroshi; Mizuno, Kensaku


    Mechanical force-induced cytoskeletal reorganization is essential for cell and tissue remodeling and homeostasis; however, the underlying cellular mechanisms remain elusive. Solo (ARHGEF40) is a RhoA-targeting guanine nucleotide exchange factor (GEF) involved in cyclical stretch-induced human endothelial cell reorientation and convergent extension cell movement in zebrafish gastrula. In this study, we show that Solo binds to keratin-8/keratin-18 (K8/K18) intermediate filaments through multiple sites. Solo overexpression promotes the formation of thick actin stress fibers and keratin bundles, whereas knockdown of Solo, expression of a GEF-inactive mutant of Solo, or inhibition of ROCK suppresses stress fiber formation and leads to disorganized keratin networks, indicating that the Solo-RhoA-ROCK pathway serves to precisely organize keratin networks, as well as to promote stress fibers. Of importance, knockdown of Solo or K18 or overexpression of GEF-inactive or deletion mutants of Solo suppresses tensile force-induced stress fiber reinforcement. Furthermore, knockdown of Solo or K18 suppresses tensile force-induced RhoA activation. These results strongly suggest that the interplay between Solo and K8/K18 filaments plays a crucial role in tensile force-induced RhoA activation and consequent actin cytoskeletal reinforcement. © 2016 Fujiwara et al.

  16. Solo and Small Practices: A Vital, Diverse Part of Primary Care. (United States)

    Liaw, Winston R; Jetty, Anuradha; Petterson, Stephen M; Peterson, Lars E; Bazemore, Andrew W


    Solo and small practices are facing growing pressure to consolidate. Our objectives were to determine (1) the percentage of family physicians in solo and small practices, and (2) the characteristics of and services provided by these practices. A total of 10,888 family physicians seeking certification through the American Board of Family Medicine in 2013 completed a demographic survey. Their practices were split into categories by size: solo, small (2 to 5 providers), medium (6 to 20 providers), and large (more than 20 providers). We also determined the rurality of the county where the physicians practiced. We developed 2 logistic regression models: one assessed predictors of practicing in a solo or small practice, while the other was restricted to solo and small practices and assessed predictors of practicing in a solo practice. More than one-half of respondents worked in solo or small practices. Small practices were the largest group (36%) and were the most likely to be located in a rural setting (20%). The likelihood of having a care coordinator and medical home certification increased with practice size. Physicians were more likely to be practicing in small or solo practices (vs medium-sized or large ones) if they were African American or Hispanic, had been working for more than 30 years, and worked in rural areas. Physicians were more likely to be practicing in small practices (vs solo ones) if they worked in highly rural areas. Family physicians in solo and small practices comprised the majority among all family physicians seeking board certification and were more likely to work in rural geographies. Extension programs and community health teams have the potential to support transformation within these practices. © 2016 Annals of Family Medicine, Inc.

  17. A taxonomy and discussion of software attack technologies (United States)

    Banks, Sheila B.; Stytz, Martin R.


    Software is a complex thing. It is not an engineering artifact that springs forth from a design by simply following software coding rules; creativity and the human element are at the heart of the process. Software development is part science, part art, and part craft. Design, architecture, and coding are equally important activities and in each of these activities, errors may be introduced that lead to security vulnerabilities. Therefore, inevitably, errors enter into the code. Some of these errors are discovered during testing; however, some are not. The best way to find security errors, whether they are introduced as part of the architecture development effort or coding effort, is to automate the security testing process to the maximum extent possible and add this class of tools to the tools available, which aids in the compilation process, testing, test analysis, and software distribution. Recent technological advances, improvements in computer-generated forces (CGFs), and results in research in information assurance and software protection indicate that we can build a semi-intelligent software security testing tool. However, before we can undertake the security testing automation effort, we must understand the scope of the required testing, the security failures that need to be uncovered during testing, and the characteristics of the failures. Therefore, we undertook the research reported in the paper, which is the development of a taxonomy and a discussion of software attacks generated from the point of view of the security tester with the goal of using the taxonomy to guide the development of the knowledge base for the automated security testing tool. The representation for attacks and threat cases yielded by this research captures the strategies, tactics, and other considerations that come into play during the planning and execution of attacks upon application software. The paper is organized as follows. Section one contains an introduction to our research

  18. Are anti-inflammatory agents effective in treating gingivitis as solo or adjunct therapies? A systematic review. (United States)

    Polak, David; Martin, Conchita; Sanz-Sánchez, Ignacio; Beyth, Nurit; Shapira, Lior


    Systematically review the scientific evidence for efficiency of anti-inflammatory agents against gingivitis, either as solo treatments or adjunctive therapies. A protocol was developed aimed to answer the following focused question: "Are anti-inflammatory agents effective in treating gingivitis as solo or adjunct therapies?" RCTs and cohort studies on anti-inflammatory agents against gingivitis studies were searched electronically. Screening, data extraction and quality assessment were conducted. The primary outcome measures were indices of gingival inflammation. A sub-analysis was performed dividing the active agents into anti-inflammatory and other drugs. The search identified 3188 studies, of which 14 RCTs met the inclusion criteria. The use of anti-inflammatory or other agents, in general showed a higher reduction in the test than in the control in terms of gingival indexes and bleeding scores. Only two RCTs on inflammatory drugs could be meta-analysed, showing a statistically significant reduction in the GI in the experimental group [WMD = -0.090; 95% CI (-0.105; -0.074); p = 0.000]. However, the contribution of both studies to the global result was unbalanced (% weight: 99.88 and 0.12 respectively). Most of the tested material showed beneficial effect as anti-inflammatory agents against gingivitis, either as a single treatment modality or as an adjunctive therapy. © 2014 John Wiley & Sons A/S.

    Directory of Open Access Journals (Sweden)

    Gustavo Souza Valladares


    SBCS (Brazilian Soil Science Society; the analytical methods proposed by EMBRAPA-Solos were used to characterize the soils. The principal component analysis was used to cluster the profiles based on morphological, physical, chemical and environmental attributes and proved adequate to group the soils under study based on the profile attributes and the grouping was well related to their taxonomy. The soil profiles were ranked by the ordinal multicriteria methods of Border, Condorcet and Copeland based on the subsidence risk. Results indicated a correlation between the methods (with exception of the Condorcet approach, unsuitable to rank the alternatives and the minimum residue, which is the classical parameter for the evaluation of subsidence, indicating efficacy to rank/classify the soil profiles in relation to subsidence risk. The quantitative approaches used are promising as evaluation tools in soil science studies.

    Biological diversity is depleting at an alarming rate. Additionally, a vast amount of biodiversity still remains undiscovered. Taxonomy has been serving the purpose of describing, naming, and classifying species for more than 250 years. DNA taxonomy and barcoding have accelerated the rate of this process, thereby providing a tool for conservation practice. DNA barcoding and traditional taxonomy have their own inherent merits and demerits. The synergistic use of both methods, in the form of integrative taxonomy, has the potential to contribute to biodiversity conservation in a pragmatic timeframe and overcome their individual drawbacks. In this review, we discuss the basics of both these methods of biological identification (traditional taxonomy and DNA barcoding), the technical advances in integrative taxonomy, and future trends. We also present a comprehensive compilation of published examples of integrative taxonomy that refer to nine topics within biodiversity conservation. Morphological and molecular species limits were observed to be congruent in ∼41% of the 58 source studies. The majority of the studies highlighted the description of cryptic diversity through the use of molecular data, whereas research areas like endemism, biological invasion, and threatened species were less discussed in the literature.

  1. Non-contact measurement of rotation angle with solo camera (United States)

    Gan, Xiaochuan; Sun, Anbin; Ye, Xin; Ma, Liqun


    For the purpose to measure a rotation angle around the axis of an object, a non-contact rotation angle measurement method based on solo camera was promoted. The intrinsic parameters of camera were calibrated using chessboard on principle of plane calibration theory. The translation matrix and rotation matrix between the object coordinate and the camera coordinate were calculated according to the relationship between the corners' position on object and their coordinates on image. Then the rotation angle between the measured object and the camera could be resolved from the rotation matrix. A precise angle dividing table (PADT) was chosen as the reference to verify the angle measurement error of this method. Test results indicated that the rotation angle measurement error of this method did not exceed +/- 0.01 degree.

    McDonald, Daniel; Price, Morgan N; Goodrich, Julia; Nawrocki, Eric P; DeSantis, Todd Z; Probst, Alexander; Andersen, Gary L; Knight, Rob; Hugenholtz, Philip


    Reference phylogenies are crucial for providing a taxonomic framework for interpretation of marker gene and metagenomic surveys, which continue to reveal novel species at a remarkable rate. Greengenes is a dedicated full-length 16S rRNA gene database that provides users with a curated taxonomy based on de novo tree inference. We developed a 'taxonomy to tree' approach for transferring group names from an existing taxonomy to a tree topology, and used it to apply the Greengenes, National Center for Biotechnology Information (NCBI) and cyanoDB (Cyanobacteria only) taxonomies to a de novo tree comprising 408,315 sequences. We also incorporated explicit rank information provided by the NCBI taxonomy to group names (by prefixing rank designations) for better user orientation and classification consistency. The resulting merged taxonomy improved the classification of 75% of the sequences by one or more ranks relative to the original NCBI taxonomy with the most pronounced improvements occurring in under-classified environmental sequences. We also assessed candidate phyla (divisions) currently defined by NCBI and present recommendations for consolidation of 34 redundantly named groups. All intermediate results from the pipeline, which includes tree inference, jackknifing and transfer of a donor taxonomy to a recipient tree (tax2tree) are available for download. The improved Greengenes taxonomy should provide important infrastructure for a wide range of megasequencing projects studying ecosystems on scales ranging from our own bodies (the Human Microbiome Project) to the entire planet (the Earth Microbiome Project). The implementation of the software can be obtained from

    Full Text Available After the description in the 19th century of two hummingbird species currently allocated to the genus Stephanoxis, Peters (1945 merged both taxa into a single species without providing any rationale. Here we re-evaluate the taxonomy and species limits of the representatives of this genus based on an extensive number of specimens. We demonstrate these taxa are better treated as full species under both the Biological and Phylogenetic Species Concepts due to their well-defined range and plumage patterns and reciprocally diagnosability. They have distinct, allopatric distributions segregated by a 160 km gap between the Serra do Mar, to the east, and Serra de Paranapiacaba, to the west, in the state of São Paulo. Stephanoxis species have ranges which are congruent with other montane bird species’ suggesting shared vicariance events during preterit interglacial periods.

  7. Transporter taxonomy - a comparison of different transport protein classification schemes. (United States)

    Viereck, Michael; Gaulton, Anna; Digles, Daniela; Ecker, Gerhard F


    Currently, there are more than 800 well characterized human membrane transport proteins (including channels and transporters) and there are estimates that about 10% (approx. 2000) of all human genes are related to transport. Membrane transport proteins are of interest as potential drug targets, for drug delivery, and as a cause of side effects and drug–drug interactions. In light of the development of Open PHACTS, which provides an open pharmacological space, we analyzed selected membrane transport protein classification schemes (Transporter Classification Database, ChEMBL, IUPHAR/BPS Guide to Pharmacology, and Gene Ontology) for their ability to serve as a basis for pharmacology driven protein classification. A comparison of these membrane transport protein classification schemes by using a set of clinically relevant transporters as use-case reveals the strengths and weaknesses of the different taxonomy approaches.

    Full Text Available The high perishability of papaya (Carica papaya L. reduces its lifespan as well as limits marketing. Coating the fruits is an alternative to aid food preservation. We aimed to evaluate the effects of coating propolis extract on the physicochemical characteristics of papaya stored at room temperature. Solo papayas cv. 'Golden' were randomly divided into five postharvest treatment groups, three forms of dip-coating (70% alcohol, hydroalcoholic extract of propolis to 2.5%, and hydroalcoholic extract of propolis to 5% and two controls (one uncoated and one with refrigerated uncoated fruits. The weight loss, firmness, soluble solids (SS, titratable acidity (TA, SS/TA, and hydrogen potential (pH were evaluated at the intervals of 4 days every 12th storage day. Sensory analysis was performed on the 4th day of storage of papayas and evaluated by untrained through the acceptance testing. Treatments “refrigerated”, “propolis 2.5%”, and “5% propolis” presented with the lowest weight loss. The firmness level for treatment propolis 5% was superior to that of control, alcohol, and 2.5% propolis treatments. The SS was greater for propolis 5% treatment, which only differed from the alcohol treatment. The TA and SS/TA did not vary with the treatments, but with the storage time. The pH of refrigerated papaya showed significant differences in relation to other treatments. The fruits subjected to refrigerated treatment presented with chilling injury. Papayas coated with propolis extract showed sensory acceptability similar to that in other treatments on the 4th day of storage. The coating of propolis extract is a promising alternative for the control of weight loss and for the maintenance of firmness in Solo papaya cv. 'Golden'.

    To develop a preliminary taxonomy of primary care medical errors. Qualitative analysis to identify categories of error reported during a randomized controlled trial of computer and paper reporting methods. The National Network for Family Practice and Primary Care Research. Family physicians. Medical error category, context, and consequence. Forty two physicians made 344 reports: 284 (82.6%) arose from healthcare systems dysfunction; 46 (13.4%) were errors due to gaps in knowledge or skills; and 14 (4.1%) were reports of adverse events, not errors. The main subcategories were: administrative failure (102; 30.9% of errors), investigation failures (82; 24.8%), treatment delivery lapses (76; 23.0%), miscommunication (19; 5.8%), payment systems problems (4; 1.2%), error in the execution of a clinical task (19; 5.8%), wrong treatment decision (14; 4.2%), and wrong diagnosis (13; 3.9%). Most reports were of errors that were recognized and occurred in reporters' practices. Affected patients ranged in age from 8 months to 100 years, were of both sexes, and represented all major US ethnic groups. Almost half the reports were of events which had adverse consequences. Ten errors resulted in patients being admitted to hospital and one patient died. This medical error taxonomy, developed from self-reports of errors observed by family physicians during their routine clinical practice, emphasizes problems in healthcare processes and acknowledges medical errors arising from shortfalls in clinical knowledge and skills. Patient safety strategies with most effect in primary care settings need to be broader than the current focus on medication errors.

  11. Revisiting the genus Photobacterium: taxonomy, ecology and pathogenesis. (United States)

    Labella, Alejandro M; Arahal, David R; Castro, Dolores; Lemos, Manuel L; Borrego, Juan J


    The genus Photobacterium, one of the eight genera included in the family Vibrionaceae, contains 27 species with valid names and it has received attention because of the bioluminescence and pathogenesis mechanisms that some of its species exhibit. However, the taxonomy and phylogeny of this genus are not completely elucidated; for example, P. logei and P. fischeri are now considered members of the genus Aliivibrio, and previously were included in the genus Vibrio. In addition, P. damselae subsp. piscicida was formed as a new combination for former Vibrio damsela and Pasteurella piscicida. Moreover, P. damselae subsp. damselae is an earlier heterotypic synonym of P. histaminum. To avoid these incovenences draft and complete genomic sequences of members of Photobacterium are increasingly becoming available and their use is now routine for many research laboratories to address diverse goals: species delineation with overall genomic indexes, phylogenetic analyses, comparative genomics, and phenotypic inference. The habitats and isolation source of the Photobacterium species include seawater, sea sediments, saline lake waters, and a variety of marine organisms with which the photobacteria establish different relationships, from symbiosis to pathogenic interactions. Several species of this genus contain bioluminescent strains in symbiosis with marine fish and cephalopods; in addition, other species enhance its growth at pressures above 1 atmosphere, by means of several high-pressure adaptation mechanisms and for this, they may be considered as piezophilic (former barophilic) bacteria. Until now, only P. jeanii, P. rosenbergii, P. sanctipauli, and the two subspecies of P. damselae have been reported as responsible agents of several pathologies on animal hosts, such as corals, sponges, fish and homeothermic animals. In this review we have revised and updated the taxonomy, ecology and pathogenicity of several members of this genus. [Int Microbiol 20(1): 1-10 (2017

  12. Physiology and taxonomy of lactobacilli surviving radurization of meat

    International Nuclear Information System (INIS)

    Hastings, J.W.


    The aim of this study was to isolate radiation-resistant lacto-bacilli from radurized (5 kGy) vacuum-packaged meat and subject them to biochemical, metabolic and physiological testing in order to gain a clearer understanding of the taxonomy of this group as well as determine characteristics which may be of technological significance. All 113 of the lactobacilli isolated were homofermentative, aciduric and were allocated to the sub-genus Streptobacterium. Numerical taxonomy by unweighted pair-group average linkage analysis revealed the existence of 5 clusters of the isolates. The same 113 isolates were classified using a purely classical taxonomic approach where the isolates were divided into 4 groups according to species designation. The basis upon which they were identified as a particular species was mainly their carbohydrate fermentation pattern. Several of the 113 isolates were selected for tests to determine characteristics of technological importance. All L.sake isolates exhibited the phenomenon of being more resistant to irradiation in the logarithmic phase than in the stationary phase of their growth cycle. This phenomenon was not characteristic of all the bacteria and was not always related to high radiation-resistance. Four L. sake isolates and three authentic strains were subjected to radiation-sensitivity testing in a natural food system where the bacteria were irradiated in minced meat packaged under four different conditions. The organisms exhibited the highest death rates under CO 2 packaging but resistance seemed to increase under N 2 -packaging. The radiation-resistance of the isolates was greater than that of the reference strains and all strains were approximately twice as resistant in the meat microenvironment than in a synthetic medium

    Full Text Available The aim of the research was to study the influence of performance anxiety on efficiency of solo music performance. Internal (self-contempt, positive self-evaluation and external criteria (musical rewards, successful solo performances, successful auditions of efficiency of solo music performance were taken into consideration. The research was grounded on studies from the field of sports psychology and on the few studies that were carried out in the field of psychology of music. The research was conducted on 94 students of Music Academy, grouped by gender and field of study (instrumentalists, solo vocalists and composers vs. students of music teaching. The symptoms of performance anxiety were measured by a part of the Performance Anxiety Questionnaire, and efficiency of solo music performance by the Efficiency of Music Performance Questionnaire. Both questionnaires were developed for the purpose of the study. The results reveal the interrelationship between the internal criteria of efficiency in solo music performance and performance anxiety. On the other hand, only trends of correlation were established between performance anxiety and the external criteria of solo music performance. The research findings imply the important role of cognition as a mediator between performance anxiety and performance efficiency.

  15. Application of the ultrametric distance to portfolio taxonomy. Critical approach and comparison with other methods (United States)

    Skórnik-Pokarowska, Urszula; Orłowski, Arkadiusz


    We calculate the ultrametric distance between the pairs of stocks that belong to the same portfolio. The ultrametric distance allows us to distinguish groups of shares that are related. In this way, we can construct a portfolio taxonomy that can be used for constructing an efficient portfolio. We also construct a portfolio taxonomy based not only on stock prices but also on economic indices such as liquidity ratio, debt ratio and sales profitability ratio. We show that a good investment strategy can be obtained by applying to the portfolio chosen by the taxonomy method the so-called Constant Rebalanced Portfolio.

  17. Reviewing Tribunal cases and nurse behaviour: putting empathy back into nurse education with Bloom's taxonomy. (United States)

    Doyle, Kerrie; Hungerford, Catherine; Cruickshank, Mary


    Recent events in the UK and Australia have shown how poor patient outcomes are achieved when the behaviour of nurses lacks empathy. The UK's Francis Inquiry and the Keogh Report both call for an increase in the 'caring and compassion' of health care workers. A review of cases presented to the nurses' disciplinary tribunal in New South Wales' (Australia) also suggests that the majority of complaints against nurses in this jurisdiction is the result of callousness or lack of empathy. Such events reinforce the need for nurse educators to support nursing students to develop the affective attributes of caring and empathy. This paper considers how to raise the awareness of undergraduate students as a first step to developing empathy by using Bloom's Taxonomy of Educational Objectives; and includes a description of how to facilitate interactions with undergraduate nursing students about caring with empathy. Enculturating empathy is an evidence-based method of increasing compassionate care in health organisations generally. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Full Text Available Foram estudados os efeitos da aplicação do composto de lixo, proveniente da cidade de São Paulo (usina de compostagem São Matheus, na presença e ausência de calcário dolomítico (para elevar a saturação por bases a 70% e de adubos minerais, sobre a condutividade elétrica (CE, pH em CaCl2 0,01 mol L-1 e em água, e acidez potencial (H + Al de 21 solos ácidos e cinco solos alcalinos, nos quais o calcário foi substituído por gesso. O experimento foi realizado em condições de casa de vegetação em delineamento em blocos ao acaso, com parcelas em faixas e três repetições. Foi verificado que a aplicação do composto de lixo promoveu o aumento da CE dos solos. Todavia, esse efeito foi inferior àquele causado pelos adubos minerais. Os maiores valores de CE (> 2 dS m-1 foram causados pelas aplicações do composto + calcário + adubo nos solos ácidos e do composto + adubo + gesso nos solos alcalinos. Porém, quanto maior a capacidade de troca catiônica (CTC inicial dos solos ácidos e pH inicial dos solos alcalinos, menores foram os efeitos dos tratamentos sobre o incremento da CE. A aplicação do composto promoveu, também, o aumento do pH e a redução da acidez potencial. Esse efeito do composto foi, em média, superior àquele causado pela aplicação do calcário. A aplicação conjunta do composto e calcário promoveu um efeito aditivo de seus efeitos isolados sobre o pH e acidez potencial do solo. A adição dos adubos minerais tendeu a reduzir o pH por causa da acidificação residual da uréia. Esse efeito foi bem evidente nos solos alcalinos. O aumento do pH e da CE foi acompanhado por uma diminuição na diferença entre os valores de pH medido em CaCl2 e em água, notadamente nos solos ácidos. A aplicação do composto de lixo para melhorar a acidez do solo, manejando-se adequadamente o calcário e adubos minerais nos solos ácidos ou gesso nos solos alcalinos, parece ser uma prática agrícola viável.

    Full Text Available City of Surakarta, known as Solo City is one of cities in Central Java Province traversed by Bengawan Solo River. Heavy rainfall in upstream area of Bengawan Solo River causes increase in high water level at downstream. Bengawan Solo River will be higher than water level in drainage system which may induce a backwater flow. Since Colonization era, the government has built dikes and barrages against backwater flow and inundation problem. One of the barrages was Demangan Barrage dividing river flow into Bengawan Solo River and Pepe River. It was equipped with total capacity pump of 12,3 m3/s. The inundation is not only caused by the backwater flow coming from Bengawan Solo River, but also surface runoff as the result of the excess rainfall which cannot be drained gravitationally to the main river if the gate was closed. Therefore, comprehensive study combining hydrology and hydraulics analysis is highly needed in order to achieve more effective flood control management. Hydrology analysis was done to estimate the direct runoff hydrograph from catchment area in Solo City to downstream of Pepe River. While in hydraulics case, hydraulic parameter in downstream of Pepe River influenced by Bengawan Solo River stream was analyzed. Both studies were simulated using software HEC-RAS 4.1.0 version. The simulation considered drainage channel, gate, pump system and dike in Pepe River downstream. Simulation using 10 years of return period in Solo City and average annual water level in Bengawan Solo River showed that Pepe River can flow through the gate, while the highest water level is still below the dike. Simulation considering 10 years of return period, water level hydrograph of Bengawan Solo River, existing pump, and gate operation inferred that Pepe River surpassed top of dike. Capacity of required pump should be more than 168,3 m3/s in order to pass 10 years of return period. By combining operational of existing pump and dike elevated up to +87,63 m

  3. Toward genetics-based virus taxonomy: comparative analysis of a genetics-based classification and the taxonomy of picornaviruses. (United States)

    Lauber, Chris; Gorbalenya, Alexander E


    Virus taxonomy has received little attention from the research community despite its broad relevance. In an accompanying paper (C. Lauber and A. E. Gorbalenya, J. Virol. 86:3890-3904, 2012), we have introduced a quantitative approach to hierarchically classify viruses of a family using pairwise evolutionary distances (PEDs) as a measure of genetic divergence. When applied to the six most conserved proteins of the Picornaviridae, it clustered 1,234 genome sequences in groups at three hierarchical levels (to which we refer as the "GENETIC classification"). In this study, we compare the GENETIC classification with the expert-based picornavirus taxonomy and outline differences in the underlying frameworks regarding the relation of virus groups and genetic diversity that represent, respectively, the structure and content of a classification. To facilitate the analysis, we introduce two novel diagrams. The first connects the genetic diversity of taxa to both the PED distribution and the phylogeny of picornaviruses. The second depicts a classification and the accommodated genetic diversity in a standardized manner. Generally, we found striking agreement between the two classifications on species and genus taxa. A few disagreements concern the species Human rhinovirus A and Human rhinovirus C and the genus Aphthovirus, which were split in the GENETIC classification. Furthermore, we propose a new supergenus level and universal, level-specific PED thresholds, not reached yet by many taxa. Since the species threshold is approached mostly by taxa with large sampling sizes and those infecting multiple hosts, it may represent an upper limit on divergence, beyond which homologous recombination in the six most conserved genes between two picornaviruses might not give viable progeny.

    Bruno B. Fischer


    Full Text Available Innovation is increasingly becoming an internationalized process and a strategy that has recently been playing a central role in this scenario is that of R&D collaboration. To assess the outcomes of this strategy we develop an evaluation of Eureka Programme’s impact for the case of Spanish companies participating in this initiative and that had projects finished in the period 2000-2005. A total of 77 firms were assessed through statistical association methods and cluster analysis. Company size, Role in the Project, Firm Sector and R&D intensity are significantly associated with the projects’ impacts on Spanish participants. A consistent taxonomy is offered in which three clusters are built: (1 Risky Innovators; (2 Inventors; and (3 Consistent Innovators.

    The purpose of this study was to evaluate the safety and performance of the Freedom Solo valve in aortic valve replacement by clinical and hemodynamic outcomes. Six hundred sixteen patients underwent aortic valve replacement in 18 European centers; mean age was 74.5 ± 5.9 years, 54.1% of the patients were male, and concomitant procedures were performed in 43.2% of the patients. The majority (69%) of the implanted sizes were 23 mm and 25 mm. At 1 year, overall survival was 94.0%, whereas freedom from valve-related death was 98.6%. There were 9 (1.5%) early (≤ 30 days) and 27 (4.4%) late (>30 days) deaths. Early and late valve-related mortality was 0.3% (n = 2) and 1.1% (n = 7), respectively. Freedom from explant was 97.6%; 10 valves were explanted for endocarditis and 4 for paravalvular leak. There were 10 (1.6%) early and 5 (0.8%) late strokes. Atrioventricular block requiring pacemaker implant occurred in 8 (1.3%) and 1 (0.2%) patients in the early and late postoperative period, respectively. Thrombocytopenia was seen in 27 cases (4.4%) in the early postoperative period. Preoperatively, 93.8% of patients were in New York Heart Association functional classes II through IV, whereas at 1 year 96.9% of patients were in New York Heart Association functional classes I and II. At 1-year follow-up, mean and peak pressure gradients were 7.2 and 14.6 mm Hg, respectively. Indexed left ventricular mass decreased by 12% from 138 g/m(2) at discharge to 122 g/m(2) at 1 year. At 1-year follow-up after Freedom Solo implantation, we found acceptable clinical results with low mortality and morbidity and good hemodynamic performance, confirming safety and effectiveness in this multicenter experience.

  6. Using a behaviour change techniques taxonomy to identify active ingredients within trials of implementation interventions for diabetes care. (United States)

    Presseau, Justin; Ivers, Noah M; Newham, James J; Knittle, Keegan; Danko, Kristin J; Grimshaw, Jeremy M


    Methodological guidelines for intervention reporting emphasise describing intervention content in detail. Despite this, systematic reviews of quality improvement (QI) implementation interventions continue to be limited by a lack of clarity and detail regarding the intervention content being evaluated. We aimed to apply the recently developed Behaviour Change Techniques Taxonomy version 1 (BCTTv1) to trials of implementation interventions for managing diabetes to assess the capacity and utility of this taxonomy for characterising active ingredients. Three psychologists independently coded a random sample of 23 trials of healthcare system, provider- and/or patient-focused implementation interventions from a systematic review that included 142 such studies. Intervention content was coded using the BCTTv1, which describes 93 behaviour change techniques (BCTs) grouped within 16 categories. We supplemented the generic coding instructions within the BCTTv1 with decision rules and examples from this literature. Less than a quarter of possible BCTs within the BCTTv1 were identified. For implementation interventions targeting providers, the most commonly identified BCTs included the following: adding objects to the environment, prompts/cues, instruction on how to perform the behaviour, credible source, goal setting (outcome), feedback on outcome of behaviour, and social support (practical). For implementation interventions also targeting patients, the most commonly identified BCTs included the following: prompts/cues, instruction on how to perform the behaviour, information about health consequences, restructuring the social environment, adding objects to the environment, social support (practical), and goal setting (behaviour). The BCTTv1 mapped well onto implementation interventions directly targeting clinicians and patients and could also be used to examine the impact of system-level interventions on clinician and patient behaviour. The BCTTv1 can be used to characterise

    Cahyani, Niken Dwi Wahyu; Choo, Kim-Kwang Raymond; Ab Rahman, Nurul Hidayah; Ashman, Helen


    Advances in technologies including development of smartphone features have contributed to the growth of mobile applications, including dating apps. However, online dating services can be misused. To support law enforcement investigations, a forensic taxonomy that provides a systematic classification of forensic artifacts from Windows Phone 8 (WP8) dating apps is presented in this study. The taxonomy has three categories, namely: Apps Categories, Artifacts Categories, and Data Partition Categories. This taxonomy is built based on the findings from a case study of 28 mobile dating apps, using mobile forensic tools. The dating app taxonomy can be used to inform future studies of dating and related apps, such as those from Android and iOS platforms. © 2018 American Academy of Forensic Sciences.

  4. Characteristics of females who sexually offend: a comparison of solo and co-offenders. (United States)

    Gillespie, Steven M; Williams, Rebecca; Elliott, Ian A; Eldridge, Hilary J; Ashfield, Sherry; Beech, Anthony R


    Although recent typologies of female sexual offenders have recognized the importance of having a co-offender, the clinical characteristics of solo and co-female sexual offenders remain poorly understood. The aim of this study was to compare solo (n = 20) and co- (n = 20) female sexual offenders on a variety of clinical characteristics. It was found that although solo and co-offenders reported similar developmental experiences and psychological dispositions, differences were found in environmental niche, offense preceding, and positive factors. Specifically, solo offenders demonstrated a greater presence of personal vulnerabilities including mental health and substance abuse difficulties. Co-offenders reported a greater presence of environmentally based factors, including a current partner who was a known sex offender and involvement with antisocial peers. It is suggested that these results have implications for understanding assessment and intervention needs for these groups of sexual offenders. © The Author(s) 2014.

  6. A tripartite taxonomy of character: Evidence for intrapersonal, interpersonal, and intellectual competencies in children. (United States)

    Park, Daeun; Tsukayama, Eli; Goodwin, Geoffrey P; Patrick, Sarah; Duckworth, Angela L


    Other than cognitive ability, what competencies should schools promote in children? How are they organized, and to what extent do they predict consequential outcomes? Separate theoretical traditions have suggested interpersonal, intrapersonal, and intellectual dimensions, reflecting how children relate to other people, manage their own goals and impulses, and engage with ideas, respectively. However, very little work has examined character empirically. In the current investigation, we partnered with middle schools that had previously identified character strengths relevant in their communities. Across three longitudinal, prospective studies, we examined the factor structure of character, associations with intelligence and Big Five personality traits, and predictive validity for consequential outcomes like peer relations, class participation, and report card grades. In Study 1, teachers rated their students on behaviors exemplifying character strengths as they played out in students' daily lives. Exploratory factor analyses yielded a three-factor structure consisting of interpersonal (interpersonal self-control, gratitude, social intelligence), intellectual (zest, curiosity), and intrapersonal (academic self-control, grit) factors of character. In Study 2, children rated their own behavior and completed a test of cognitive ability. Confirmatory factor analyses supported the same three-factor structure, and these factors were only weakly associated with cognitive ability. In Study 3, teachers provided character ratings; in parallel, students completed measures of character as well as Big Five personality factors. As expected, intellectual, interpersonal, and intrapersonal character factors related to Big Five openness to experience, agreeableness, and conscientiousness, respectively. Across studies, positive peer relations were most consistently predicted by interpersonal character, class participation by intellectual character, and report card grades by

  7. Product Engineering Class in the Software Safety Risk Taxonomy for Building Safety-Critical Systems (United States)

    Hill, Janice; Victor, Daniel


    When software safety requirements are imposed on legacy safety-critical systems, retrospective safety cases need to be formulated as part of recertifying the systems for further use and risks must be documented and managed to give confidence for reusing the systems. The SEJ Software Development Risk Taxonomy [4] focuses on general software development issues. It does not, however, cover all the safety risks. The Software Safety Risk Taxonomy [8] was developed which provides a construct for eliciting and categorizing software safety risks in a straightforward manner. In this paper, we present extended work on the taxonomy for safety that incorporates the additional issues inherent in the development and maintenance of safety-critical systems with software. An instrument called a Software Safety Risk Taxonomy Based Questionnaire (TBQ) is generated containing questions addressing each safety attribute in the Software Safety Risk Taxonomy. Software safety risks are surfaced using the new TBQ and then analyzed. In this paper we give the definitions for the specialized Product Engineering Class within the Software Safety Risk Taxonomy. At the end of the paper, we present the tool known as the 'Legacy Systems Risk Database Tool' that is used to collect and analyze the data required to show traceability to a particular safety standard

  8. An Optimized Player Taxonomy Model for Mobile MMORPGs with Millions of Users

    Directory of Open Access Journals (Sweden)

    Fang You


    Full Text Available Massively multiplayer online role-playing games (MMORPGs have great potential as sites for research within the social and human-computer interaction. In the MMORPGs, a stability player taxonomy model is very important for game design. It helps to balance different types of players and improve business strategy of the game. The players in mobile MMORPGs are also connected with social networks; many studies only use the player's own attributes statistics or questionnaire survey method to predict player taxonomy, so lots of social network relations' information will be lost. In this paper, by analyzing the impacts of player's social network, commercial operating data from mobile MMORPGs is used to establish our player taxonomy model (SN model. From the model results, social network-related information in mobile MMORPGs will be considered as important factors to pose this optimized player taxonomy model. As experimental results showed, compared with another player taxonomy model (RA model, our proposed player taxonomy model can achieve good results: classification is more stable.

  9. Towards the Development of a Taxonomy for Visualisation of Streamed Geospatial Data (United States)

    Sibolla, B. H.; Van Zyl, T.; Coetzee, S.


    Geospatial data has very specific characteristics that need to be carefully captured in its visualisation, in order for the user and the viewer to gain knowledge from it. The science of visualisation has gained much traction over the last decade as a response to various visualisation challenges. During the development of an open source based, dynamic two-dimensional visualisation library, that caters for geospatial streaming data, it was found necessary to conduct a review of existing geospatial visualisation taxonomies. The review was done in order to inform the design phase of the library development, such that either an existing taxonomy can be adopted or extended to fit the needs at hand. The major challenge in this case is to develop dynamic two dimensional visualisations that enable human interaction in order to assist the user to understand the data streams that are continuously being updated. This paper reviews the existing geospatial data visualisation taxonomies that have been developed over the years. Based on the review, an adopted taxonomy for visualisation of geospatial streaming data is presented. Example applications of this taxonomy are also provided. The adopted taxonomy will then be used to develop the information model for the visualisation library in a further study.

    Full Text Available Determinou-se a silica solúvel nos horizontes superficial e B2 de 44 perfis de solos do Estado de São Paulo. A extração da silica com solução 0,0025M de cloreto de cálcio evitou a dispersão dos solos e forneceu resultados em média apenas 8% menores do que a silica solúvel em água. Os resultados variaram de 2,2 a 92,2 ppm de SiO2. Verificou-se que, para solos com teores semelhantes de argila, os teores de silica solúvel foram maiores para solos com horizonte B textural, quando comparados com solos de horizonte B latossólico. Dentro dos agrupamentos de solos com horizonte B textural e horizonte B latossólico, os teores de silica solúvel foram maiores para os solos mais argilosos. Não foi observada relação entre silica solúvel e o pH dos solos.The extraction of soluble silica of soils with 0.0025M calcium chloride solution avoided dispersion of clay and results were on the average only 8% lower than water soluble silica. The results for surface and B2 horizons of 44 soil profiles of the State of São Paulo varied between 2.2 and 92.9 ppm of SiO2. For soils with similar clay contents, soluble silica was higher for soil with argillic B horizons as compared with soils with oxic B horizons. Within each group of soils, higher soluble silica results were associated with higher clay contents. Soluble silica apparently was not related to soil pH.

    Full Text Available Parte da variabilidade dos índices de produção agrícola está associada com as características do solo e da paisagem. Dessa forma, práticas de manejo, como a adubação, devem levar em consideração esta variabilidade. O sensoriamento remoto é uma ferramenta que pode fornecer, de maneira rápida, informações para o manejo do solo, pois relaciona a radiação eletromagnética com os atributos do solo. Assim, este trabalho teve como objetivo avaliar o comportamento espectral, em dois níveis de aquisição de dados (terrestre e orbital, de diferentes classes de solos ao longo de toposseqüências na região de São Carlos e Ibaté, SP. Para isso, amostras de terra georreferenciadas foram coletadas em 319 pontos, em três profundidades. Em seguida, obtiveram-se os dados radiométricos em laboratório, na faixa espectral entre 450 e 2.500 nm. Os mesmos locais amostrados na camada superficial, no campo, foram avaliados na imagem de satélite. A partir dos resultados obtidos, pode-se concluir que: (a teores de areia grossa, argila e matéria orgânica, e cor tiveram relação com a reflectância dos solos; (b ao longo das vertentes ocorrem variações nos dados espectrais dos solos; e (c solos da mesma ordem taxonômica, porém com classes texturais diferentes, apresentam diferentes comportamentos espectrais, podendo ser discriminados por sensoriamento remoto.Part of agricultural production index variability is associated with soil and landscape characteristics. Management practices such as fertilizer application should therefore take the soil spatial variability into account. Remote sensing is a tool that can provide faster information for soil management because it relates electromagnetic radiation with soil attributes.

  18. Thrombocytopenia following implantation of the stentless biological sorin freedom SOLO valve. (United States)

    Gersak, Borut; Gartner, Urska; Antonic, Miha


    Stentless biological valves have proven advantages in hemodynamic performance and left ventricular function compared to stented biological valves. Following a marked postoperative fall in the platelet count of patients after implantation of the Freedom SOLO valve, the study aim was to confirm clinical observations that this effect was more severe in patients receiving Freedom SOLO valves than in those receiving St. Jude Medical (SJM) mechanical aortic valves. Preoperative and postoperative platelet counts were compared in two groups of patients who underwent aortic valve replacement (AVR) without any concomitant procedures between January and December 2007. Patients received either a Freedom SOLO valve (n = 28) or a SJM mechanical valve (n = 41). Mean values of platelet counts were compared using three multiple linear regression models. Platelet counts were significantly lower in the Freedom SOLO group than in the SJM group from the first postoperative day (POD 1) up to POD 6 (p SOLO group the platelet count fell below 30x10(9)/l, while the lowest level in the SJM group was 75x10(9)/l. Based on multiple linear regression models, the type of valve implanted had a statistically significant influence on postoperative platelet counts on POD 1, POD 3, and POD 5 (p SOLO group.

  19. SOLO: a meiotic protein required for centromere cohesion, coorientation, and SMC1 localization in Drosophila melanogaster. (United States)

    Yan, Rihui; Thomas, Sharon E; Tsai, Jui-He; Yamada, Yukihiro; McKee, Bruce D


    Sister chromatid cohesion is essential to maintain stable connections between homologues and sister chromatids during meiosis and to establish correct centromere orientation patterns on the meiosis I and II spindles. However, the meiotic cohesion apparatus in Drosophila melanogaster remains largely uncharacterized. We describe a novel protein, sisters on the loose (SOLO), which is essential for meiotic cohesion in Drosophila. In solo mutants, sister centromeres separate before prometaphase I, disrupting meiosis I centromere orientation and causing nondisjunction of both homologous and sister chromatids. Centromeric foci of the cohesin protein SMC1 are absent in solo mutants at all meiotic stages. SOLO and SMC1 colocalize to meiotic centromeres from early prophase I until anaphase II in wild-type males, but both proteins disappear prematurely at anaphase I in mutants for mei-S332, which encodes the Drosophila homologue of the cohesin protector protein shugoshin. The solo mutant phenotypes and the localization patterns of SOLO and SMC1 indicate that they function together to maintain sister chromatid cohesion in Drosophila meiosis.

  3. Uranium and Molybdenum extraction from a Cerro Solo deposit ore

    International Nuclear Information System (INIS)

    Becquart, Elena T.; Arias, Maria J.; Fuente, Juan C. de la; Misischia, Yamila A.; Santa Cruz, Daniel E.; Tomellini, Guido C.


    Cerro Solo, located in Chubut, Argentina, is a sandstone type uranium-molybdenum deposit. Good recovery of both elements can be achieved by acid leaching of the ore but the presence of molybdenum in pregnant liquors is an inconvenient to uranium separation and purification. A two steps process is developed. A selective alkaline leaching of the ore with sodium hydroxide allows separating and recovering of molybdenum and after solid-liquid separation, the ore is acid leached to recover uranium. Several samples averaging 0,2% uranium and 0,1% molybdenum with variable U/Mo ratio have been used and in both steps, leaching and oxidant reagents concentration, temperature and residence time in a stirred tank leaching have been studied. In alkaline leaching molybdenum recoveries greater than 96% are achieved, with 1% uranium extraction. In acid leaching up to 93% of the uranium is extracted and Mo/U ratio in solvent extraction feed is between 0,013 and 0,025. (author)

  4. Multilevel Hierarchy of Economic Space: Formation of Evolutionary Taxonomy

    Directory of Open Access Journals (Sweden)

    Daniil Petrovich Frolov


    Full Text Available The article considers methodological problems of hierarchical structuring of economic space. The evolution survey of multilevel analysis concepts reveals a dominant role of two-level (micro- macro neoclassical models because of the path dependence effect. In institutional and evolutionary theories the application of mesoanalysis and three-level models gradually becomes more active, but conventions in the field of taxonomy are extremely inert. The main methodological problems of a hierarchical taksonomization of economic space include the problem of taxonomical «rupture» of a subject and a method of Economics, the problem of an identification of the level (rank and scale of economic phenomena, the problem of an identification of subjects and business location, the problem of terminological unification. The author›s hierarchical model of economic space is developed in a context of the generalized evolutionary theory on the basis of multilevel population thinking. The model offers differentiation of industrial and territorial (spatial division and cooperation of labour and, more widely, economic activity. Branches and generation are treated as objects of the industrial analysis, population and ecocenosis – objects of the spatial analysis that allows reintegration of spatial formations in the system of economic analysis. The study of mesolevels and interlevel relations is particularly important. Institutionalism can be considered as metanarrative, i.e. one of universal languages of Economics. Scales and ranks of the functions assigned to subjects and objects of transactions define level differentiation of institutions’ forms in economic space

  5. Spinosaur taxonomy and evolution of craniodental features: Evidence from Brazil.

    Directory of Open Access Journals (Sweden)

    Marcos A F Sales

    Full Text Available Fossil sites from Brazil have yielded specimens of spinosaurid theropods, among which the most informative include the cranial remains of Irritator, Angaturama, and Oxalaia. In this work some of their craniodental features are reinterpreted, providing new data for taxonomic and evolutionary issues concerning this particular clade of dinosaurs. The mesial-most tooth of the left maxilla of the holotype of Irritator is regarded as representing the third tooth position, which is also preserved in the holotype of Angaturama. Thus, both specimens cannot belong to the same individual, contrary to previous assumptions, although they could have been the same taxon. In addition, the position of the external nares of Irritator is more comparable to those of Baryonyx and Suchomimus instead of other spinosaurine spinosaurids. In fact, with regards to some craniodental features, Brazilian taxa represent intermediate conditions between Baryonychinae and Spinosaurinae. Such a scenario is corroborated by our cladistic results, which also leave open the possibility of the former subfamily being non-monophyletic. Furthermore, the differences between spinosaurids regarding the position and size of the external nares might be related to distinct feeding habits and degrees of reliance on olfaction. Other issues concerning the evolution and taxonomy of Spinosauridae require descriptions of additional material for their clarification.

  6. Dynamics of market correlations: taxonomy and portfolio analysis. (United States)

    Onnela, J-P; Chakraborti, A; Kaski, K; Kertész, J; Kanto, A


    The time dependence of the recently introduced minimum spanning tree description of correlations between stocks, called the "asset tree" has been studied in order to reflect the financial market taxonomy. The nodes of the tree are identified with stocks and the distance between them is a unique function of the corresponding element of the correlation matrix. By using the concept of a central vertex, chosen as the most strongly connected node of the tree, an important characteristic is defined by the mean occupation layer. During crashes, due to the strong global correlation in the market, the tree shrinks topologically, and this is shown by a low value of the mean occupation layer. The tree seems to have a scale-free structure where the scaling exponent of the degree distribution is different for "business as usual" and "crash" periods. The basic structure of the tree topology is very robust with respect to time. We also point out that the diversification aspect of portfolio optimization results in the fact that the assets of the classic Markowitz portfolio are always located on the outer leaves of the tree. Technical aspects such as the window size dependence of the investigated quantities are also discussed.

  7. Shedding subspecies: The influence of genetics on reptile subspecies taxonomy. (United States)

    Torstrom, Shannon M; Pangle, Kevin L; Swanson, Bradley J


    The subspecies concept influences multiple aspects of biology and management. The 'molecular revolution' altered traditional methods (morphological traits) of subspecies classification by applying genetic analyses resulting in alternative or contradictory classifications. We evaluated recent reptile literature for bias in the recommendations regarding subspecies status when genetic data were included. Reviewing characteristics of the study, genetic variables, genetic distance values and noting the species concepts, we found that subspecies were more likely elevated to species when using genetic analysis. However, there was no predictive relationship between variables used and taxonomic recommendation. There was a significant difference between the median genetic distance values when researchers elevated or collapsed a subspecies. Our review found nine different concepts of species used when recommending taxonomic change, and studies incorporating multiple species concepts were more likely to recommend a taxonomic change. Since using genetic techniques significantly alter reptile taxonomy there is a need to establish a standard method to determine the species-subspecies boundary in order to effectively use the subspecies classification for research and conservation purposes.

  8. Consumer Preferences for Local Food: Testing an Extended Norm Taxonomy

    Directory of Open Access Journals (Sweden)

    Julius Wenzig


    Full Text Available Consumer attitudes toward consuming and buying locally produced food are well studied. By contrast, the topic of consumer preferences for local food, with a special emphasis on the role of norms, still lacks empirical evidence. To study the influence of norms and morals on the intention to buy local food products, a quantitative study (N = 327 focusing on external social and internalized moral norms was conducted using the constructs of the theory of planned behavior in combination with an extended norm taxonomy and the perceived consumer effectiveness measure. The norm constructs consisted of two different personal norms, integrated and introjected, and two social norms, descriptive and injunctive. In a factor analysis, two factors for social norms but only one for personal norms were obtained. Multiple regressions explained 50 percent of the variance in intentions and 29 percent of the variance in past behavior. Norm constructs were proven important in the model, as personal norms had the largest effect among all constructs on intentions, and descriptive norms strongly influenced past behavior. An additional mediation analysis showed that personal norms were internalized social injunctive norms and that intentions mediated the relationship between all constructs. The implications of the findings and recommendations for future research are given accordingly.

  9. Microstructure taxonomy based on spatial correlations: Application to microstructure coarsening

    International Nuclear Information System (INIS)

    Fast, Tony; Wodo, Olga; Ganapathysubramanian, Baskar; Kalidindi, Surya R.


    To build materials knowledge, rigorous description of the material structure and associated tools to explore and exploit information encoded in the structure are needed. These enable recognition, categorization and identification of different classes of microstructure and ultimately enable to link structure with properties of materials. Particular interest lies in the protocols capable of mining the essential information in large microstructure datasets and building robust knowledge systems that can be easily accessed, searched, and shared by the broader materials community. In this paper, we develop a protocol based on automated tools to classify microstructure taxonomies in the context of coarsening behavior which is important for long term stability of materials. Our new concepts for enhanced description of the local microstructure state provide flexibility of description. The mathematical description of microstructure that capture crucial attributes of the material, although central to building materials knowledge, is still elusive. The new description captures important higher order spatial information, but at the same time, allows down sampling if less information is needed. We showcase the classification protocol by studying coarsening of binary polymer blends and classifying steady state structures. We study several microstructure descriptions by changing the microstructure local state order and discretization and critically evaluate their efficacy. Our analysis revealed the superior properties of microstructure representation is based on the first order-gradient of the atomic fraction.

  11. Molecular Phylogenetic: Organism Taxonomy Method Based on Evolution History

    Directory of Open Access Journals (Sweden)

    N.L.P Indi Dharmayanti


    Full Text Available Phylogenetic is described as taxonomy classification of an organism based on its evolution history namely its phylogeny and as a part of systematic science that has objective to determine phylogeny of organism according to its characteristic. Phylogenetic analysis from amino acid and protein usually became important area in sequence analysis. Phylogenetic analysis can be used to follow the rapid change of a species such as virus. The phylogenetic evolution tree is a two dimensional of a species graphic that shows relationship among organisms or particularly among their gene sequences. The sequence separation are referred as taxa (singular taxon that is defined as phylogenetically distinct units on the tree. The tree consists of outer branches or leaves that represents taxa and nodes and branch represent correlation among taxa. When the nucleotide sequence from two different organism are similar, they were inferred to be descended from common ancestor. There were three methods which were used in phylogenetic, namely (1 Maximum parsimony, (2 Distance, and (3 Maximum likehoood. Those methods generally are applied to construct the evolutionary tree or the best tree for determine sequence variation in group. Every method is usually used for different analysis and data.

  12. Conservation of biodiversity through taxonomy, data publication, and collaborative infrastructures. (United States)

    Costello, Mark J; Vanhoorne, Bart; Appeltans, Ward


    Taxonomy is the foundation of biodiversity science because it furthers discovery of new species. Globally, there have never been so many people involved in naming species new to science. The number of new marine species described per decade has never been greater. Nevertheless, it is estimated that tens of thousands of marine species, and hundreds of thousands of terrestrial species, are yet to be discovered; many of which may already be in specimen collections. However, naming species is only a first step in documenting knowledge about their biology, biogeography, and ecology. Considering the threats to biodiversity, new knowledge of existing species and discovery of undescribed species and their subsequent study are urgently required. To accelerate this research, we recommend, and cite examples of, more and better communication: use of collaborative online databases; easier access to knowledge and specimens; production of taxonomic revisions and species identification guides; engagement of nonspecialists; and international collaboration. "Data-sharing" should be abandoned in favor of mandated data publication by the conservation science community. Such a step requires support from peer reviewers, editors, journals, and conservation organizations. Online data publication infrastructures (e.g., Global Biodiversity Information Facility, Ocean Biogeographic Information System) illustrate gaps in biodiversity sampling and may provide common ground for long-term international collaboration between scientists and conservation organizations. © 2015 Society for Conservation Biology.

  13. Governance of Interoperability in Intergovernmental Services - Towards an Empirical Taxonomy

    Directory of Open Access Journals (Sweden)

    Herbert Kubicek


    Full Text Available High quality and comfortable online delivery of governmental services often requires the seamless exchange of data between two or more government agencies. Smooth data exchange, in turn, requires interoperability of the databases and workflows in the agencies involved. Interoperability (IOP is a complex issue covering purely technical aspects such as transmission protocols and data exchange formats, but also content-related semantic aspects such as identifiers and the meaning of codes as well as organizational, contractual or legal issues. Starting from IOP frameworks which provide classifications of what has to be standardized, this paper, based on an ongoing research project, adopts a political and managerial view and tries to clarify the governance of achieving IOP, i.e. where and by whom IOPstandards are developed and established and how they are put into operation. By analyzing 32 cases of successful implementation of IOP in E-Government services within the European Union empirical indicators for different aspects of governance are proposed and applied to develop an empirical taxonomy of different types of IOP governance which can be used for future comparative research regarding success factors, barriers etc.

  14. Revolutionary thoughts on taxonomy: declarations of independence and interdependence

    Directory of Open Access Journals (Sweden)

    Quentin D. Wheeler


    Full Text Available Credible biological research depends on accurate species identifications, reliable scientific names, and an evolutionary context provided by a phylogeny or phylogenetic classification. The emphasis on such taxonomic services has detracted from the fundamental taxonomic research necessary to create and sustain such knowledge systems. A taxonomic declaration of independence is presented, emphasizing the unique mission, goals, and needs of taxonomists and taxonomic (collection-based institutions and the non-experimental yet scientifically rigorous epistemology of taxonomy. At the same time taxonomic interdependence is declared. Questions pursued by taxonomists are planetary in scale and can only be answered given international collaboration and coordination in the growth and development of natural history collections and taxonomic hypotheses. Reciprocity of open access is urged between all nations and the taxonomic community creating information. Countries home to species diversity should allow access to taxon experts so that the world's species are discovered and described. In exchange all specimens collected should be in publicly accessible museums and all resultant taxonomic data, information, and knowledge should be openly available to all who can use them.

  15. Leaf arrangements are invalid in the taxonomy of orchid species

    Directory of Open Access Journals (Sweden)

    Anna Jakubska-Busse


    Full Text Available The selection and validation of proper distinguishing characters are of crucial importance in taxonomic revisions. The modern classifications of orchids utilize the molecular tools, but still the selection and identification of the material used in these studies is for the most part related to general species morphology. One of the vegetative characters quoted in orchid manuals is leaf arrangement. However, phyllotactic diversity and ontogenetic changeability have not been analysed in detail in reference to particular taxonomic groups. Therefore, we evaluated the usefulness of leaf arrangements in the taxonomy of the genus Epipactis Zinn, 1757. Typical leaf arrangements in shoots of this genus are described as distichous or spiral. However, in the course of field research and screening of herbarium materials, we indisputably disproved the presence of distichous phyllotaxis in the species Epipactis purpurata Sm. and confirmed the spiral Fibonacci pattern as the dominant leaf arrangement. In addition, detailed analyses revealed the presence of atypical decussate phyllotaxis in this species, as well as demonstrated the ontogenetic formation of pseudowhorls. These findings confirm ontogenetic variability and plasticity in E. purpurata. Our results are discussed in the context of their significance in delimitations of complex taxa within the genus Epipactis.

  16. Fish Ontology framework for taxonomy-based fish recognition (United States)

    Ali, Najib M.; Khan, Haris A.; Then, Amy Y-Hui; Ving Ching, Chong; Gaur, Manas


    Life science ontologies play an important role in Semantic Web. Given the diversity in fish species and the associated wealth of information, it is imperative to develop an ontology capable of linking and integrating this information in an automated fashion. As such, we introduce the Fish Ontology (FO), an automated classification architecture of existing fish taxa which provides taxonomic information on unknown fish based on metadata restrictions. It is designed to support knowledge discovery, provide semantic annotation of fish and fisheries resources, data integration, and information retrieval. Automated classification for unknown specimens is a unique feature that currently does not appear to exist in other known ontologies. Examples of automated classification for major groups of fish are demonstrated, showing the inferred information by introducing several restrictions at the species or specimen level. The current version of FO has 1,830 classes, includes widely used fisheries terminology, and models major aspects of fish taxonomy, grouping, and character. With more than 30,000 known fish species globally, the FO will be an indispensable tool for fish scientists and other interested users. PMID:28929028

  17. An overview of the taxonomy of Attalea (Arecaceae

    Directory of Open Access Journals (Sweden)

    Jean-Christophe Pintaud


    Full Text Available The genus Attalea (Arecaceae is distributed in continental habitats of the Neotropical region and in some Caribbean islands. Life forms of Attalea species vary from small acaulescent palms to tall and massive palms, always solitary. The ecological range of the genus encompasses most of the Neotropical ecosystems, from coastal sand dunes to sub-Andean forests up to 1600 m in elevation, lowland wet to dry forests, savannas, swamps, etc. The taxonomy of the genus has been poorly understood due to conflicting genus and species concepts that exist since the last decades. Taxonomical problems have been caused by the lack of adequate material, especially species of large size, loss of many types and difficulties in interpreting hybrids. In this article, I review the most recent taxonomic literature on Attalea. The number of species in Attalea varies from 29 to 67 depending on different authors, with a maximum estimate of 73 species when combining the revised publications. There is a consensus for the validity of 20 species among modern palm taxonomists. The most conflicting species or group of species are discussed in detail as well as the taxonomic significance of some characters such as the pattern of insertion of staminate flowers on rachillae, insertion of pinnae on rachis, and arrangement of fibrous strands in the endocarp.

  18. Conceptual clustering and its relation to numerical taxonomy

    International Nuclear Information System (INIS)

    Fisher, D.; Langley, P.


    Artificial Intelligence (AI) methods for machine learning can be viewed as forms of exploratory data analysis, even though they differ markedly from the statistical methods generally connoted by the term. The distinction between methods of machine learning and statistical data analysis is primarily due to differences in the way techniques of each type represent data and structure within data. That is, methods of machine learning are strongly biased toward symbolic (as opposed to numeric) data representations. The authors explore this difference within a limited context, devoting the bulk of our chapter to the explication of conceptual clustering, an extension to the statistically based methods of numerical taxonomy. In conceptual clustering the formation of object cluster is dependent on the quality of 'higher level' characterization, termed concepts, of the clusters. The form of concepts used by existing conceptual clustering systems (sets of necessary and sufficient conditions) is described in some detail. This is followed by descriptions of several conceptual clustering techniques, along with sample output. They conclude with a discussion of how alternative concept representations might enhance the effectiveness of future conceptual clustering systems

  20. Towards a new taxonomy of idiopathic orofacial pain. (United States)

    Woda, Alain; Tubert-Jeannin, Stéphanie; Bouhassira, Didier; Attal, Nadine; Fleiter, Bernard; Goulet, Jean-Paul; Gremeau-Richard, Christelle; Navez, Marie Louise; Picard, Pascale; Pionchon, Paul; Albuisson, Eliane


    There is no current consensus on the taxonomy of the different forms of idiopathic orofacial pain (stomatodynia, atypical odontalgia, atypical facial pain, facial arthromyalgia), which are sometimes considered as separate entities and sometimes grouped together. In the present prospective multicentric study, we used a systematic approach to help to place these different painful syndromes in the general classification of chronic facial pain. This multicenter study was carried out on 245 consecutive patients presenting with chronic facial pain (>4 months duration). Each patient was seen by two experts who proposed a diagnosis, administered a 111-item questionnaire and filled out a standardized 68-item examination form. Statistical processing included univariate analysis and several forms of multidimensional analysis. Migraines (n=37), tension-type headache (n=26), post-traumatic neuralgia (n=20) and trigeminal neuralgia (n=13) tended to cluster independently. When signs and symptoms describing topographic features were not included in the list of variables, the idiopathic orofacial pain patients tended to cluster in a single group. Inside this large cluster, only stomatodynia (n=42) emerged as a distinct homogenous subgroup. In contrast, facial arthromyalgia (n=46) and an entity formed with atypical facial pain (n=25) and atypical odontalgia (n=13) could only be individualised by variables reflecting topographical characteristics. These data provide grounds for an evidence-based classification of idiopathic facial pain entities and indicate that the current sub-classification of these syndromes relies primarily on the topography of the symptoms.

  1. Otoliths as an integral part in fossil fish taxonomy

    Directory of Open Access Journals (Sweden)

    Christoph Gierl


    Full Text Available Otoliths are small structures in the skull of fishes. They are responsible for hearing and orientation in the 3-dimensional space. They also hold valuable information regarding the taxonomy. Their outline, the shape of the sulcus and other features allow the determination of a fish even to the species level. A lot of fossil species are solely based on otoliths because of their good chance of preservation. Gobies are in this case no different. An additional challenge in gobies is their high similarity between species concerning the preservable parts. Fossil skeletons that are 20 Million years old can show only few differences compared to recent gobies. These features are often hardly recognizable due to their preservation. As a consequence many fossil gobies have been assigned to the genus Gobius sensu lato. Examples are two gobies from the Miocene of Southern Germany. They have a unique combination of characters (six branchiostegals, palatine resembling a “T”, no entopterygoid that allows the rectification of a new fossil genus but the two species are hardly distinguishable based only on the skeleton. The key hints in having two species are the otoliths. They show slight but consistent differences in their outline. This shows that otoliths can be a key feature in species identification. They should also be taken into consideration by recent fish species. Not to mention their possible phylogenetic potential that remains to be explored.

Salienta-se a fragilidade dos ambientes degradados de baixa declividade frente às altas taxas de perdas de solo e água, que, no período de 17 meses de monitoramento e com chuvas dentro da normalidade para o município, totalizaram 63 dias com ocorrências de escoamento, em solos que tendem à saturação por períodos prolongados. Portanto, o transporte das partículas de solo superficialmente está atrelado à baixa drenagem do terreno e à perda da resistência do solo, corroborando em períodos longos de umidade antecedente, sendo este um dos fatores decisivos para se iniciar o escoamento superficial.

    Full Text Available Estudos foram realizados no Departamento de Ciência do Solo da Universidade Federal de Lavras (MG, no período de novembro/1999 a janeiro/2000, com o objetivo de avaliar a sobrevivência de estirpe e isolados de rizóbio em solo contaminado com metais pesados e verificar a relação entre tolerância do rizóbio a metais pesados em meio de cultura e sua sobrevivência em solo contaminado. Foram utilizados os dois microrganismos mais tolerantes [BR-4406 (estirpe recomendada para Enterolobium spp. e UFLA-01-457 (isolado de solo contaminado, ambos pertencentes ao gênero Bradyrhizobium ] e os dois mais sensíveis (UFLA-01-486 e UFLA-01-510, isolados de solo contaminado, pertencentes ao gênero Azorhizobium , todos selecionados de um grupo de 60estirpes/isolados em estudos prévios deste laboratório, em meio de cultura suplementado com metais pesados.Empregaram-se misturas de um Latossolo Vermelho-Escuro (LE que continham 0, 15 e 45% (v/v de um Latossolo Vermelho-Amarelo plíntico contaminado com Zn, Cd, Pb e Cu. As misturas de solo contaminado foram inoculadas com 20mL de cultura em YM na fase log das estirpes mencionadas, as quais foram testadas separadamente com três repetições. A avaliação do número de células viáveis no solo, realizada aos 0, 7, 14, 21 e 28dias de incubação, pelo método das diluições sucessivas e inoculação em placas com meio YMA, revelou comportamento diferenciado entre os organismos estudados. O número médio de células que sobreviveram ao final de 28 dias de incubação foi de (em UFCg-1de solo: 10(10,36, 10(10,29 e 10(9,70, para Bradyrhizobium, e 10(9,36, 10(7,54 e 0, para Azorhizobium em misturas de 0, 15 e 45% de solo contaminado, respectivamente. Portanto, houve maior sobrevivência de Bradyrhizobium do que de Azorhizobium , indicando maior tolerância a metais pesados do primeiro gênero.Como Bradyrhizobium foi também mais tolerante "in vitro", os resultados indicam haver relação entre o

    Full Text Available O uso de fertilizantes que contêm baixos teores de enxofre (S, em solos com baixos teores de matéria orgânica, pode resultar em limitação desse nutriente para as culturas. O uso do S-elementar como fertilizante, isoladamente ou associado a fórmulas comerciais, pode reduzir os custos de adubação em solos deficientes de S. Os objetivos deste estudo foram: a verificar se, em dois solos tropicais, ocorre oxidação de S-elementar; b avaliar se o período de incubação de seis dias sugerido por Janzen & Bettany (1987a é adequado para estimar a oxidação do S-elementar e c medir o efeito da oxidação do S-elementar sobre o pH do solo. Para isso, foi realizado um experimento com amostras de um ARGISSOLO VERMELHO AMARELO eutrófico abruptíco e de um LATOSSOLO VERMELHO DISTRÓFICO típico. As amostras dos dois solos foram incubadas com seis doses de enxofre (0, 1,5, 3,0, 6,0 9,0 e 12g de So kg-1 de solo por períodos entre 0 e 70 dias. A incubação foi feita em estufa, a uma temperatura de 27o + 1o C. Ambos os solos tiveram capacidade para oxidar o S-elementar para S-sulfato, forma disponível à planta. No argissolo, o teor de S-sulfato resultante da oxidação do S-elementar foi 563mg dm-3 de solo, enquanto que, no latossolo, foi de 207mg dm-3 de solo, indicando capacidade diferenciada de ambos para oxidar o S-elementar. Em ambos os solos houve diminuição do pH, sendo mais acentuada para o argissolo. O período de incubação para avaliação da oxidação do S-elementar de seis dias sugerido por Janzen & Bettany (1987a parece ser insuficiente.

  5. Reexamining organizational configurations: an update, validation, and expansion of the taxonomy of health networks and systems. (United States)

    Dubbs, Nicole L; Bazzoli, Gloria J; Shortell, Stephen M; Kralovec, Peter D


    To (a) assess how the original cluster categories of hospital-led health networks and systems have changed over time; (b) identify any new patterns of cluster configurations; and (c) demonstrate how additional data can be used to refine and enhance the taxonomy measures. DATA SOURCES; 1994 and 1998 American Hospital Association (AHA) Annual Survey of Hospitals. As in the original taxonomy, separate cluster solutions are identified for health networks and health systems by applying three strategic/structural dimensions (differentiation, integration, and centralization) to three components of the health service/product continuum (hospital services, physician arrangements, and provider-based insurance activities). Factor, cluster, and discriminant analyses are used to analyze the 1998 data. Descriptive and comparative methods are used to analyze the updated 1998 taxonomy relative to the original 1994 version. The 1998 cluster categories are similar to the original taxonomy, however, they reveal some new organizational configurations. For the health networks, centralization of product/service lines is occurring more selectively than in the past. For the health systems, participation has grown in and dispersed across a more diverse set of decentralized organizational forms. For both networks and systems, the definition of centralization has changed over time. In its updated form, the taxonomy continues to provide policymakers and practitioners with a descriptive and contextual framework against which to assess organizational programs and policies. There is a need to continue to revisit the taxonomy from time to time because of the persistent evolution of the U.S. health care industry and the consequent shifting of organizational configurations in this arena. There is also value in continuing to move the taxonomy in the direction of refinement/expansion as new opportunities become available.

  6. Dynamic taxonomies applied to a web-based relational database for geo-hydrological risk mitigation (United States)

    Sacco, G. M.; Nigrelli, G.; Bosio, A.; Chiarle, M.; Luino, F.


    In its 40 years of activity, the Research Institute for Geo-hydrological Protection of the Italian National Research Council has amassed a vast and varied collection of historical documentation on landslides, muddy-debris flows, and floods in northern Italy from 1600 to the present. Since 2008, the archive resources have been maintained through a relational database management system. The database is used for routine study and research purposes as well as for providing support during geo-hydrological emergencies, when data need to be quickly and accurately retrieved. Retrieval speed and accuracy are the main objectives of an implementation based on a dynamic taxonomies model. Dynamic taxonomies are a general knowledge management model for configuring complex, heterogeneous information bases that support exploratory searching. At each stage of the process, the user can explore or browse the database in a guided yet unconstrained way by selecting the alternatives suggested for further refining the search. Dynamic taxonomies have been successfully applied to such diverse and apparently unrelated domains as e-commerce and medical diagnosis. Here, we describe the application of dynamic taxonomies to our database and compare it to traditional relational database query methods. The dynamic taxonomy interface, essentially a point-and-click interface, is considerably faster and less error-prone than traditional form-based query interfaces that require the user to remember and type in the "right" search keywords. Finally, dynamic taxonomy users have confirmed that one of the principal benefits of this approach is the confidence of having considered all the relevant information. Dynamic taxonomies and relational databases work in synergy to provide fast and precise searching: one of the most important factors in timely response to emergencies.

  7. Bioactivity of fungal endophytes as a function of endophyte taxonomy and the taxonomy and distribution of their host plants.

    Directory of Open Access Journals (Sweden)

    Sarah J Higginbotham

    Full Text Available Fungal endophytes--fungi that grow within plant tissues without causing immediate signs of disease--are abundant and diverse producers of bioactive secondary metabolites. Endophytes associated with leaves of tropical plants are an especially exciting and relatively untapped source of novel compounds. However, one major challenge in drug discovery lies in developing strategies to efficiently recover highly bioactive strains. As part of a 15-year drug discovery project, foliar endophytes were isolated from 3198 plant samples (51 orders, 105 families and at least 232 genera of angiosperms and ferns collected in nine geographically distinct regions of Panama. Extracts from culture supernatants of >2700 isolates were tested for bioactivity (in vitro percent inhibition of growth, % IG against a human breast cancer cell line (MCF-7 and the causative agents of malaria, leishmaniasis, and Chagas' disease. Overall, 32.7% of endophyte isolates were highly active in at least one bioassay, including representatives of diverse fungal lineages, host lineages, and collection sites. Up to 17% of isolates tested per assay were highly active. Most bioactive strains were active in only one assay. Fungal lineages differed in the incidence and degree of bioactivity, as did fungi from particular plant taxa, and greater bioactivity was observed in endophytes isolated from plants in cloud forests vs. lowland forests. Our results suggest that using host taxonomy and forest type to tailor plant collections, and selecting endophytes from specific orders or families for cultivation, will markedly increase the efficiency and efficacy of discovering bioactive metabolites for particular pharmaceutical targets.

Assim, Cambissolos e Latossolos tendem a ocupar os níveis mais altos da paisagem brasileira, ao passo que 75 % dos perfis de Espodossolos e de Plintossolos situam-se em cotas inferiores a 200 m. Além das potencialidades de uso evidenciadas, a estruturação atual da base de dados permite outras aplicações para atender necessidades específicas de estudo, inclusive no que tange a investigações relacionadas ao sistema de classificação de solos que vem sendo desenvolvido no país.Brazilian soil science is outstanding in tropical soil research, with a wealth of information on the soils of the country. However, this knowledge is not readily available. The aim of this study was to increase the range of a national soil profile database, based on soil surveys of wide extent. The soil taxonomy was updated based on the latest version of the Brazilian Soil Classification System. The updated database was also evaluated for coverage and potential for quantitative analyses. For this purpose, the data were arranged in an electronic database and soil classification updated up to the fourth categorical level of the current taxonomic system. Mainly in the first three levels, the name updating procedure was reliable. Restrictions were observed at the fourth level (sub-group, as measured by the degree of confidence used for the assessment of taxonomic classification accuracy. By updating the soil profiles to the current and standard taxonomic criteria, the databases were internally standardized and became comparable to external data, e.g. spatial distribution, altitude and climate types. Profiles of the different taxonomic groups nationwide were well- represented, as well as most federal States. Furthermore, soil profiles from several taxonomic groups were related to the Köppen climate zones

Foram avaliadas a granulometria e a composição química das amostras de solo. O comportamento espectral do solo foi obtido em laboratório, utilizando espectroradiômetro entre 400 e 2.500 nm. Os coprólitos de minhoca apresentaram 2 a 3 vezes mais fósforo e um incremento de 30 a 50% na matéria orgânica em relação ao horizonte superficial do solo. Os agregados de cupins e formigas apresentaram composição química semelhante à dos horizontes subsuperficiais dos solos. O comportamento espectral dos agregados biológicos variou conforme sua composição química e profundidade de ação dos animais. No caso da minhoca, as curvas de reflectância foram semelhantes às do horizonte superficial para os três solos. Para as estruturas de cupim e formiga, tanto a composição química como o comportamento espectral corresponderam ao horizonte subsuperficial no LV e TR.

  10. Benefits of walking and solo experiences in UK wild places. (United States)

    Freeman, Elizabeth; Akhurst, Jacqueline; Bannigan, Katrina; James, Hazel


    This paper examines human-nature interaction and how therapeutic this relationship is by investigating the efficacy of structured outdoor experience. Two walking and solo experience (WSEs) explored university students' (aged 20-43 years) perceptions of walking through and being with nature. The first was a 5-day journey (n = 4; 3 females and 1 male) and the second (n = 5; 3 females and 2 males) took place over two weekends, with a 2-week interval in-between. Pre- and post-experience interviews, journal writing, group discussions and a 9-month follow-up interviews were used to collect data and thematic analysis [Braun and Clarke (Using thematic analysis in psychology. Qual Res Psychol 2006;3:77-101.)] was applied. Both WSEs were considered together during analysis, as well as comparisons made between the two, in order to evaluate implications for practice. Benefits of the WSE that contributed to a general sense of well-being were: (i) gaining a sense of freedom and escape; (ii) gaining a sense of awareness and sensitivity to one's environment and its influence (iii) gaining confidence in being able to cope and take action; (iv) gaining a sense of perspective on and appreciation for life. Furthermore, the meaning participants formed in relation to their environment before, during and after the WSE, and the activity within that environment, played a role in their sense of well-being and in their motivations to re-access nature in other places. Findings suggest that WSEs are a cost effective way to give rise to beneficial and durable experiences, but a more holistic approach to policy is needed. © The Author 2016.

  11. A taxonomy of nursing care organization models in hospitals. (United States)

    Dubois, Carl-Ardy; D'Amour, Danielle; Tchouaket, Eric; Rivard, Michèle; Clarke, Sean; Blais, Régis


    Over the last decades, converging forces in hospital care, including cost-containment policies, rising healthcare demands and nursing shortages, have driven the search for new operational models of nursing care delivery that maximize the use of available nursing resources while ensuring safe, high-quality care. Little is known, however, about the distinctive features of these emergent nursing care models. This article contributes to filling this gap by presenting a theoretically and empirically grounded taxonomy of nursing care organization models in the context of acute care units in Quebec and comparing their distinctive features. This study was based on a survey of 22 medical units in 11 acute care facilities in Quebec. Data collection methods included questionnaire, interviews, focus groups and administrative data census. The analytical procedures consisted of first generating unit profiles based on qualitative and quantitative data collected at the unit level, then applying hierarchical cluster analysis to the units' profile data. The study identified four models of nursing care organization: two professional models that draw mainly on registered nurses as professionals to deliver nursing services and reflect stronger support to nurses' professional practice, and two functional models that draw more significantly on licensed practical nurses (LPNs) and assistive staff (orderlies) to deliver nursing services and are characterized by registered nurses' perceptions that the practice environment is less supportive of their professional work. This study showed that medical units in acute care hospitals exhibit diverse staff mixes, patterns of skill use, work environment design, and support for innovation. The four models reflect not only distinct approaches to dealing with the numerous constraints in the nursing care environment, but also different degrees of approximations to an "ideal" nursing professional practice model described by some leaders in the

  12. Genome-Based Microbial Taxonomy Coming of Age. (United States)

    Hugenholtz, Philip; Skarshewski, Adam; Parks, Donovan H


    Reconstructing the complete evolutionary history of extant life on our planet will be one of the most fundamental accomplishments of scientific endeavor, akin to the completion of the periodic table, which revolutionized chemistry. The road to this goal is via comparative genomics because genomes are our most comprehensive and objective evolutionary documents. The genomes of plant and animal species have been systematically targeted over the past decade to provide coverage of the tree of life. However, multicellular organisms only emerged in the last 550 million years of more than three billion years of biological evolution and thus comprise a small fraction of total biological diversity. The bulk of biodiversity, both past and present, is microbial. We have only scratched the surface in our understanding of the microbial world, as most microorganisms cannot be readily grown in the laboratory and remain unknown to science. Ground-breaking, culture-independent molecular techniques developed over the past 30 years have opened the door to this so-called microbial dark matter with an accelerating momentum driven by exponential increases in sequencing capacity. We are on the verge of obtaining representative genomes across all life for the first time. However, historical use of morphology, biochemical properties, behavioral traits, and single-marker genes to infer organismal relationships mean that the existing highly incomplete tree is riddled with taxonomic errors. Concerted efforts are now needed to synthesize and integrate the burgeoning genomic data resources into a coherent universal tree of life and genome-based taxonomy.

  14. Toward a Novel Multilocus Phylogenetic Taxonomy for the Dermatophytes. (United States)

    de Hoog, G Sybren; Dukik, Karolina; Monod, Michel; Packeu, Ann; Stubbe, Dirk; Hendrickx, Marijke; Kupsch, Christiane; Stielow, J Benjamin; Freeke, Joanna; Göker, Markus; Rezaei-Matehkolaei, Ali; Mirhendi, Hossein; Gräser, Yvonne


    Type and reference strains of members of the onygenalean family Arthrodermataceae have been sequenced for rDNA ITS and partial LSU, the ribosomal 60S protein, and fragments of β-tubulin and translation elongation factor 3. The resulting phylogenetic trees showed a large degree of correspondence, and topologies matched those of earlier published phylogenies demonstrating that the phylogenetic representation of dermatophytes and dermatophyte-like fungi has reached an acceptable level of stability. All trees showed Trichophyton to be polyphyletic. In the present paper, Trichophyton is restricted to mainly the derived clade, resulting in classification of nearly all anthropophilic dermatophytes in Trichophyton and Epidermophyton, along with some zoophilic species that regularly infect humans. Microsporum is restricted to some species around M. canis, while the geophilic species and zoophilic species that are more remote from the human sphere are divided over Arthroderma, Lophophyton and Nannizzia. A new genus Guarromyces is proposed for Keratinomyces ceretanicus. Thirteen new combinations are proposed; in an overview of all described species it is noted that the largest number of novelties was introduced during the decades 1920-1940, when morphological characters were used in addition to clinical features. Species are neo- or epi-typified where necessary, which was the case in Arthroderma curreyi, Epidermophyton floccosum, Lophophyton gallinae, Trichophyton equinum, T. mentagrophytes, T. quinckeanum, T. schoenleinii, T. soudanense, and T. verrucosum. In the newly proposed taxonomy, Trichophyton contains 16 species, Epidermophyton one species, Nannizzia 9 species, Microsporum 3 species, Lophophyton 1 species, Arthroderma 21 species and Ctenomyces 1 species, but more detailed studies remain needed to establish species borderlines. Each species now has a single valid name. Two new genera are introduced: Guarromyces and Paraphyton. The number of genera has increased, but

  15. Nuclear and original DNA application in Oryza taxonomy and phylogeny

    International Nuclear Information System (INIS)

    Romero, Gabriel O.


    Conventional taxonomy and phylogeny of germplasm are based on the tedious characterization of morphological variation. The ability to assay DNA variation that underlies morphological variation offers great promise as a convenient alternative for the genetic characterization of germplasm. Restriction fragment length polymorphism (RFLP) was used to survey DNA variation in 22 species of the genus Oryza. At the ribosomal DNA (rDNA) multigene family, 15 rDNA spacer length (sl) variants were identified using restriction enzyme Sst1 and wheatrDNA unit as probe. Particular sl variants predominated in certain isozyme groups of O. sativa, indicating a potential of sl ploymorphism in varietal classification. The distribution of sl variants supports the origin of O. sativa and O. nivara from O. rufipogon, and that O. spontanea arose from introgressions among O. sativa, O. nivara, and O. rufipogon. The distribution also suggests that the CCgenome, of all the genomes in the Officinalis complex, may be closest to the Sativa complex genomes, and it affirms the genetic position of the Officinalis complex intermediate between the Sativa and Ridleyi complexes. Variation at the Oryza organelle genomes was probed with a maize mitochondrial gene, atpA, a wheat chloroplast inverted repeat segment, p6. Results indicated that the complexes can be differentiated by their mitochondrial genome, but not their chloroplast genome when digested by Sst1 or BamH1. Therefore, the natural DNA variation in the nuclear and mitochondrial genomes has demonstrated great potential in complementing the conventional basis of taxa classification and phylogeny in the genus Oryza.

  16. Systematic comparative content analysis of 17 psychosocial work environment questionnaires using a new taxonomy. (United States)

    Kop, Jean-Luc; Althaus, Virginie; Formet-Robert, Nadja; Grosjean, Vincent


    Many questionnaires have been developed to measure how psychosocial characteristics are perceived in a work environment. But the content validity of these questionnaires has rarely been questioned due to the absence of a reference taxonomy for characteristics of work environments. To propose an exhaustive taxonomy of work environment characteristics involved in psychosocial risks and to apply this taxonomy to questionnaires on workplace psychosocial factors. The taxonomy was developed by categorizing factors present in the main theoretical models of the field. Questionnaire items most frequently cited in scientific literature were retained for classification. The taxonomy was structured into four hierarchical levels and comprises 53 categories. The 17 questionnaires analyzed included 927 items: 59 from the "physical environment" category, 116 from the "social environment" category, 236 from the "work activity" category, 255 from the "activity management" category, and 174 from the "organizational context" category. There are major content differences among analyzed questionnaires. This study offers a means for selecting a scale on the basis of content.

  17. Implementation of a novel taxonomy based on cognitive work analysis in the assessment of safety performance. (United States)

    Niskanen, Toivo


    The aim of this study was to examine how the developed taxonomy of cognitive work analysis (CWA) can be applied in combination with statistical analysis regarding different sociotechnical categories. This study applied a combination of quantitative and qualitative methodologies. Workers (n = 120) and managers (n = 85) in the chemical industry were asked in a questionnaire how different occupational safety and health (OSH) measures were being implemented. The exploration of the qualitative CWA taxonomy consisted of an analysis of the following topics: (a) work domain; (b) control task; (c) strategies; (d) social organization and cooperation; (e) worker competencies. The following hypotheses were supported - activities of the management had positive impacts on the aggregated variables: near-accident investigation and instructions (H 1 ); OSH training (H 2 ); operations, technical processes and safe use of chemicals (H 3 ); use of personal protective equipment (H 4 ); measuring, follow-up and prevention of major accidents (H 5 ). The CWA taxonomy was applied in mixed methods when testing H 1 -H 5 . A special approach is to analyze the work demands of complex sociotechnical systems with the taxonomy of CWA. In problem-solving, the CWA taxonomy should seek to capitalize on the strengths and minimize the limitations of safety performance.

  18. Constructing a working taxonomy of functional Ada software components for real-time embedded system applications (United States)

    Wallace, Robert


    A major impediment to a systematic attack on Ada software reusability is the lack of an effective taxonomy for software component functions. The scope of all possible applications of Ada software is considered too great to allow the practical development of a working taxonomy. Instead, for the purposes herein, the scope of Ada software application is limited to device and subsystem control in real-time embedded systems. A functional approach is taken in constructing the taxonomy tree for identified Ada domain. The use of modular software functions as a starting point fits well with the object oriented programming philosophy of Ada. Examples of the types of functions represented within the working taxonomy are real time kernels, interrupt service routines, synchronization and message passing, data conversion, digital filtering and signal conditioning, and device control. The constructed taxonomy is proposed as a framework from which a need analysis can be performed to reveal voids in current Ada real-time embedded programming efforts for Space Station.

  19. A taxonomy of anatomical and pathological entities to support commenting on radiographs (preliminary clinical evaluation)

    International Nuclear Information System (INIS)

    Cosson, Philip; Dash, Robert


    It has been shown that radiographers have a lot to offer the patient by providing their expert opinion in a timely intervention; including the possibility of Radiographer Led Discharge. Some excellent paper based ‘commenting’ systems have been developed locally and the Society and College of Radiographers has issued national guidance with a pro-forma to support implementation. However, delivery and audit of the PCE service can be burdensome. There is also an ongoing training need linked in to annual reviews. This paper provides a brief introduction to the field of controlled vocabularies and ontologies in radiology and serves to identify their potential for PCE systems. The current work has constructed a prototype taxonomy and accompanying ontology (list of relationships) that enable the generation of radiographer comments using an electronic, fast, and structured web based interface. For example, in the current implementation any one of thousands of possible unique comments could be constructed by making just six selections from filtered lists of terms. The prototype taxonomy has been tested to refine and validate the concept. The resulting taxonomy and its evolution is described here. Finally, the taxonomy was trialled by 23 participants who generated structured PCE's after reviewing 27 cases on DICOM workstations. An analysis of agreement between participants and the ‘gold standard’ is presented. In conclusion, a taxonomy has been created that would provide for: a standardised framework for training staff and students, efficient and robust delivery of the service, and audit of individual practice

  20. Abstraction of complex concepts with a refined partial-area taxonomy of SNOMED (United States)

    Wang, Yue; Halper, Michael; Wei, Duo; Perl, Yehoshua; Geller, James


    An algorithmically-derived abstraction network, called the partial-area taxonomy, for a SNOMED hierarchy has led to the identification of concepts considered complex. The designation “complex” is arrived at automatically on the basis of structural analyses of overlap among the constituent concept groups of the partial-area taxonomy. Such complex concepts, called overlapping concepts, constitute a tangled portion of a hierarchy and can be obstacles to users trying to gain an understanding of the hierarchy’s content. A new methodology for partitioning the entire collection of overlapping concepts into singly-rooted groups, that are more manageable to work with and comprehend, is presented. Different kinds of overlapping concepts with varying degrees of complexity are identified. This leads to an abstract model of the overlapping concepts called the disjoint partial-area taxonomy, which serves as a vehicle for enhanced, high-level display. The methodology is demonstrated with an application to SNOMED’s Specimen hierarchy. Overall, the resulting disjoint partial-area taxonomy offers a refined view of the hierarchy’s structural organization and conceptual content that can aid users, such as maintenance personnel, working with SNOMED. The utility of the disjoint partial-area taxonomy as the basis for a SNOMED auditing regimen is presented in a companion paper. PMID:21878396

    Full Text Available This article tries to analyze the franchise business system of Ayam Bakar Wong Solo Restaurant through the Islamic economics perspective. The franchise business system applied by the Ayam Bakar Wong Solo is a cooperation (shirkah with the type of shirkah mudârabah, where there is a cooperation between the Ayam Bakar Wong Solo as a manager (mudârib and investors as owners of capital (sahib al-mâl. Both parties allied in the venture capital and the advantage of the alliance is divided in accordance with the agreements that have been agreed between the two. The Ayam Bakar Wong Solo offers two forms of shirkah mudârabah, namely mudârabah mutlaqah and mudârabah muqayyadah. It is found that there is a correspondence between the execution of the Ayam Bakar Wong Solo franchise and shirkah mudârabah practices in Islamic economics because the franchise system which is run has been suitably qualified and has met the rukn of shirkah mudârabah. However, there is a concept of franchis-ing which is more in line with Islamic economics, namely the principle of sharing in mudârabah and mushârakah as a substitute for a franchise concept with franchise fee and royalty fee.

  2. A Comparison of Solo and Multiplayer Active Videogame Play in Children with Unilateral Cerebral Palsy. (United States)

    Howcroft, Jennifer; Fehlings, Darcy; Wright, Virginia; Zabjek, Karl; Andrysek, Jan; Biddiss, Elaine


    Active videogames (AVGs) have potential in terms of physical activity and therapy for children with cerebral palsy. However, the effect of social interaction on AVG play has not yet been assessed. The objective of this study is to determine if multiplayer AVG versus solo affects levels of energy expenditure and movement patterns. Fifteen children (9.77 [standard deviation (SD) 1.78] years old) with hemiplegic cerebral palsy (Gross Motor Function Classification System Level I) participated in solo and multiplayer Nintendo(®) "Wii™ Boxing" (Nintendo, Inc., Redmond, WA) AVG play while energy expenditure and punching frequency were monitored. Moderate levels of physical activity were achieved with no significant differences in energy measures during multiplayer and solo play. Dominant arm punching frequency increased during the multiplayer session from 95.75 (SD 37.93) punches/minute to 107.77 (SD 36.99) punches/minute. Conversely, hemiplegic arm punching frequency decreased from 39.05 (SD 29.57) punches/minutes to 30.73 (SD 24.74) punches/minutes during multiplayer game play. Children enjoyed multiplayer more than solo play. Opportunities to play AVGs with friends and family may translate to more frequent participation in this moderate physical activity. Conversely, increased hemiplegic limb use during solo play may have therapeutic advantages. As such, new strategies are recommended to promote use of the hemiplegic hand during multiplayer AVG play and to optimize commercial AVG systems for applications in virtual reality therapy.

  3. Initial experience with the Freedom Solo® stentless aortic valve in a low volume centre. (United States)

    Kolseth, Solveig Moss; Nordhaug, Dag; Stenseth, Roar; Wahba, Alexander


    Freedom Solo is a stentless biological aortic valve which is implanted supra-annularly with a single suture line. An increased risk of postoperative thrombocytopenia in the early postoperative period has been reported in recent studies. In our study we evaluated postoperative haemodynamic performance and thrombocyte-levels. Thirty seven patients who underwent valve implantation of the Sorin Freedom Solo stentless valve were included. The haemodynamic performance of the valve was evaluated by transthoracic echocardiography postoperatively at the fourth day (mean) and after a median of 4.2 months. The mean gradient (mmHg) of Freedom Solo was 7.5 at four days and 8.6 at 4.2 months. Postoperatively no patient had more than grade 1 leakage. Seven percent of the patients had a reduction of thrombocytes to less than 20% of the preoperative level. Seventy six percent had a minimum postoperative thrombocyte level less than 100*10(9)/L. The 30 days mortality in our patient material was zero. Implantation of the Freedom Solo valve was uncomplicated in our experience. Favourable transvalvular gradients and no significant leaks were found. In accordance with the literature, we found a high percentage of patients having a postoperative level of thrombocytes less than 100*10(9)/L after implantation of Freedom Solo.

  4. The Effects of Musician's Earplugs on Acoustic and Perceptual Measures of Choral and Solo Sound. (United States)

    Cook-Cunningham, Sheri L


    The purpose of this investigation was to assess the effects of earplugs on acoustical and perceptual measures of choral and solo sound. The researcher tested the effects of musician's earplugs on choral and solo timbre and singer perceptions. Members of an intact women's university choir recorded Dona Nobis Pacem under two conditions, no earplugs and with earplugs over time. Approximately half of the choir members also participated as soloists, recording Over the Rainbow under the same two conditions. All recordings were analyzed using long-term average spectra (LTAS). After participating in each recording session, the participants responded to a questionnaire about ability to hear self (solo and choral context) and ability to hear others (choral context) under two conditions, no earplugs and with earplugs. LTAS results revealed that wearing earplugs in a choral setting caused decreased mean signal energy (>1 dB), resulting in less resonant singing. LTAS results also indicated that wearing earplugs in a solo setting had less effect on mean signal energy, resulting in a mean difference solo setting. Findings from this study could provide important information when structuring hearing conservation strategies. Copyright © 2017 The Voice Foundation. Published by Elsevier Inc. All rights reserved.

  5. Taxonomies of Cyber Adversaries and Attacks: A Survey of Incidents and Approaches

    Energy Technology Data Exchange (ETDEWEB)

    Meyers, C A; Powers, S S; Faissol, D M


    In this paper we construct taxonomies of cyber adversaries and methods of attack, drawing from a survey of the literature in the area of cyber crime. We begin by addressing the scope of cyber crime, noting its prevalence and effects on the US economy. We then survey the literature on cyber adversaries, presenting a taxonomy of the different types of adversaries and their corresponding methods, motivations, maliciousness, and skill levels. Subsequently we survey the literature on cyber attacks, giving a taxonomy of the different classes of attacks, subtypes, and threat descriptions. The goal of this paper is to inform future studies of cyber security on the shape and characteristics of the risk space and its associated adversaries.

  6. The Bootstrap, the Jackknife, and the Randomization Test: A Sampling Taxonomy. (United States)

    Rodgers, J L


    A simple sampling taxonomy is defined that shows the differences between and relationships among the bootstrap, the jackknife, and the randomization test. Each method has as its goal the creation of an empirical sampling distribution that can be used to test statistical hypotheses, estimate standard errors, and/or create confidence intervals. Distinctions between the methods can be made based on the sampling approach (with replacement versus without replacement) and the sample size (replacing the whole original sample versus replacing a subset of the original sample). The taxonomy is useful for teaching the goals and purposes of resampling schemes. An extension of the taxonomy implies other possible resampling approaches that have not previously been considered. Univariate and multivariate examples are presented.

  7. Reconciling taxonomy and phylogenetic inference: formalism and algorithms for describing discord and inferring taxonomic roots

    Directory of Open Access Journals (Sweden)

    Matsen Frederick A


    Full Text Available Abstract Background Although taxonomy is often used informally to evaluate the results of phylogenetic inference and the root of phylogenetic trees, algorithmic methods to do so are lacking. Results In this paper we formalize these procedures and develop algorithms to solve the relevant problems. In particular, we introduce a new algorithm that solves a "subcoloring" problem to express the difference between a taxonomy and a phylogeny at a given rank. This algorithm improves upon the current best algorithm in terms of asymptotic complexity for the parameter regime of interest; we also describe a branch-and-bound algorithm that saves orders of magnitude in computation on real data sets. We also develop a formalism and an algorithm for rooting phylogenetic trees according to a taxonomy. Conclusions The algorithms in this paper, and the associated freely-available software, will help biologists better use and understand taxonomically labeled phylogenetic trees.

    Full Text Available RESUMO Com o objetivo de avaliar a sobrevivência de Macrophomina phaseolina em solo submetido a diferentes coberturas, conduziu-se dois experimentos em casa de vegetação, no delineamento inteiramente casualizado, em esquema fatorial 5 x 2, com cinco coberturas (Brachiaria brizantha, Pennisetum glaucum, Crotalaria spectabilis, solo coberto com filme de polietileno e solo sem cobertura e solo esterilizado e não esterilizado. No primeiro experimento, as plantas foram cultivadas em vasos e dessecadas, para posterior plantio do feijão-caupi e no segundo, a semeadura da cultura foi realizada em sucessão ao primeiro cultivo. Nos dois experimentos foram colocadas em cada vaso a 10 cm de profundidade, no dia do plantio da cultura, quatro bolsas de tecido contendo, cada uma, 10 gramas de inóculo de M. phaseolina, das quais, duas foram retiradas aos 30 dias após o plantio e duas no final do ciclo da cultura, para posterior plaqueamento e determinação da sobrevivência. Realizou-se também o monitoramento das temperaturas máximas e mínimas diárias do solo. Os tratamentos com solo coberto com material vegetal apresentaram menor elevação da temperatura em relação ao solo coberto com filme de polietileno e sem cobertura, que elevaram a temperatura em até 5,9 e 3,9 ºC, respectivamente, em relação ao solo coberto com palhada de P. glaucum. O solo coberto com filme de polietileno e sem cobertura apresentaram maiores taxas de sobrevivência de M. phaseolina e o solo coberto com palhada de P. glaucum a menor taxa. Maior sobrevivência foi observada no solo não esterilizado.

Este trabalho teve como objetivo avaliar o fluxo difusivo de Zn em amostras de um solo de textura argilosa (Latossolo Vermelho-Escuro - LE, outro de textura média (Podzólico Vermelho-Amarelo - PV e um terceiro de textura arenosa (Latossolo Vermelho-Amarelo - LV, submetidos a níveis de pH: pH natural (4,38 e 5,40, para o LE; natural (4,87 e 6,00, para o PV, e somente pH natural (4,64, para o LV, e a três fontes de Zn (ZnCl2, ZnEDTA e ZnSO4 nas doses de 0, 20 e 40 mg dm-3 de Zn. As unidades experimentais constituíram-se de 400 cm³ de amostras de solo, colocadas em câmaras feitas de tubos de PVC, com 10 cm de diâmetro e 5 cm de altura, contendo, cada câmara, uma lâmina de resina trocadora de cátions ácido forte (modelo CR61CZR IONICS, Inc como dreno de Zn, nas dimensões de 2,0 x 5,0 cm, colocada à profundidade de 2,5 cm no meio da câmara. As amostras, umedecidas até a capacidade de campo, foram incubadas por um período de 15 dias à temperatura de 24 ± 4ºC. Após esse período, as lâminas foram retiradas, realizando-se a extração do Zn adsorvido às lâminas de resina. O pH do solo demonstrou ser fator de grande importância no controle do fluxo difusivo do Zn, acarretando-lhe grande diminuição quando da elevação de pH. De modo geral, o fluxo difusivo de Zn foi menor com o aumento do teor de argila do solo. O fluxo difusivo de Zn foi maior, nos três solos, quando a fonte utilizada foi ZnCl2.

  14. Tephritid taxonomy into the 21st century - Research opportunities and applications

    International Nuclear Information System (INIS)

    Drew, R.A.I.; Romig, M.C.


    We write with the firm conviction that taxonomic research forms the essential foundation for all other areas of investigation within the field of biology. This has been well demonstrated in the Tephritidae and is a position at which we have arrived through many years' experience in fruit fly systematic research covering taxonomy, behaviour, biology, ecology and pest control. The importance of sound taxonomic research is highlighted at this time by the known presence of many sibling species complexes across the family. Within the Dacinae, for example, major pest species often occur within groups of closely related species, most of which are not pests. The dorsalis complex of Southeast Asia and the musae complex of Papua New Guinea are examples. Tephritid taxonomy has a long history (over two centuries) and rich heritage with some 4,500 species having been described since the mid-1700s. This research has been carried out in major research centres around the world and particularly in Australia, Europe, Hawaii, mainland USA and South Africa. In Mexico in February 1998, a significant meeting was held on the biology/behaviour and taxonomy of Tephritidae. Specialist researchers in this area presented valuable and interesting data on 'Phylogeny and Evolution of Behaviour' in fruit flies. In summarising current knowledge on the taxonomy and biology of the Tephritidae, the meeting highlighted the outstanding achievements of taxonomy in its contributions to both basic research and pest management programmes over many decades of tephritid studies world-wide. This presentation provides a link between the meetings in Mexico and Penang and enables us to present a summary of our current knowledge and genuine valuable applications of tephritid taxonomy to the overall fruit fly research and pest management effort. In doing this, this presentation also fits into the theme of this conference in Penang, 'Fruit Flies- current global scenario'

  16. Identification of magnetic minerals in the fine-grain sediment on the Bengawan Solo River (United States)

    Purnama, B.; Kusuma, R.; Legowo, B.; Suharyana; Wijayanta, A. T.


    The magnetic mineral content in the fine sediment of Bengawan Solo River is discussed. The fine sediment is obtained on the upper part of the tributary of Bengawan Solo River. Magnetic minerals are separated using permanent magnets. Furthermore the magnetic minerals are overnight dried using oven at 100°C. FTIR characterization indicate that the magnetic minerals in the fine sediment of Bengawan Solo River have the same characteristics as minerals in Cilacap and Purwokerto areas. Magnetic minerals are estimated to form at wave number k = 569.03 cm-1. This hematite content increase to 70.67% after anealling treatment at 600°C for 4 hours in atmosphere condition. This result is interesting because the heating process increases the hematite content. Within results, the magnetic properties of the sample will change.

  18. Analyzing recommender systems for health promotion using a multidisciplinary taxonomy: A scoping review. (United States)

    Hors-Fraile, Santiago; Rivera-Romero, Octavio; Schneider, Francine; Fernandez-Luque, Luis; Luna-Perejon, Francisco; Civit-Balcells, Anton; de Vries, Hein


    any of the selected studies, did not use principles of tailoring, and did not assess (cost)-effectiveness. Health recommender systems may be further improved by using relevant behavior change strategies and by implementing essential characteristics of tailored interventions. In addition, many of the features required to assess each of the domain aspects, the methodological and procedural aspects, and technical aspects were not reported in the studies. The studies analyzed presented few evidence in support of the positive effects of using health recommender systems in terms of cost-effectiveness and patient health outcomes. This is why future studies should ensure that all the proposed features are covered in our multidisciplinary taxonomy, including integration with electronic health records and the incorporation of health promotion theoretical factors and behavior change theories. This will render those studies more useful for policymakers since they will cover all aspects needed to determine their impact toward meeting SDG3. Copyright © 2017. Published by Elsevier B.V.

    Objective. With the increasing societal awareness of the prevalence and impact of acute pain, there is a need to develop an acute pain classification system that both reflects contemporary mechanistic insights and helps guide future research and treatment. Existing classifications of acute pain conditions are limiting, with a predominant focus on the sensory experience (e.g., pain intensity) and pharmacologic consumption. Consequently, there is a need to more broadly characterize and classify the multidimensional experience of acute pain. Setting. Consensus report following expert panel involving the Analgesic, Anesthetic, and Addiction Clinical Trial Translations, Innovations, Opportunities, and Networks (ACTTION), American Pain Society (APS), and American Academy of Pain Medicine (AAPM). Methods. As a complement to a taxonomy recently developed for chronic pain, the ACTTION public-private partnership with the US Food and Drug Administration, the APS, and the AAPM convened a consensus meeting of experts to develop an acute pain taxonomy using prevailing evidence. Key issues pertaining to the distinct nature of acute pain are presented followed by the agreed-upon taxonomy. The ACTTION-APS-AAPM Acute Pain Taxonomy will include the following dimensions: 1) core criteria, 2) common features, 3) modulating factors, 4) impact/functional consequences, and 5) putative pathophysiologic pain mechanisms. Future efforts will consist of working groups utilizing this taxonomy to develop diagnostic criteria for a comprehensive set of acute pain conditions. Perspective. The ACTTION-APS-AAPM Acute Pain Taxonomy (AAAPT) is a multidimensional acute pain classification system designed to classify acute pain along the following dimensions: 1) core criteria, 2) common features, 3) modulating factors, 4) impact/functional consequences, and 5) putative pathophysiologic pain mechanisms. Conclusions. Significant numbers of patients still suffer from significant acute pain

  3. "Communicate to vaccinate": the development of a taxonomy of communication interventions to improve routine childhood vaccination. (United States)

    Willis, Natalie; Hill, Sophie; Kaufman, Jessica; Lewin, Simon; Kis-Rigo, John; De Castro Freire, Sara Bensaude; Bosch-Capblanch, Xavier; Glenton, Claire; Lin, Vivian; Robinson, Priscilla; Wiysonge, Charles S


    Vaccination is a cost-effective public health measure and is central to the Millennium Development Goal of reducing child mortality. However, childhood vaccination coverage remains sub-optimal in many settings. While communication is a key feature of vaccination programmes, we are not aware of any comprehensive approach to organising the broad range of communication interventions that can be delivered to parents and communities to improve vaccination coverage. Developing a classification system (taxonomy) organised into conceptually similar categories will aid in: understanding the relationships between different types of communication interventions; facilitating conceptual mapping of these interventions; clarifying the key purposes and features of interventions to aid implementation and evaluation; and identifying areas where evidence is strong and where there are gaps. This paper reports on the development of the 'Communicate to vaccinate' taxonomy. The taxonomy was developed in two stages. Stage 1 included: 1) forming an advisory group; 2) searching for descriptions of interventions in trials (CENTRAL database) and general health literature (Medline); 3) developing a sampling strategy; 4) screening the search results; 5) developing a data extraction form; and 6) extracting intervention data. Stage 2 included: 1) grouping the interventions according to purpose; 2) holding deliberative forums in English and French with key vaccination stakeholders to gather feedback; 3) conducting a targeted search of grey literature to supplement the taxonomy; 4) finalising the taxonomy based on the input provided. The taxonomy includes seven main categories of communication interventions: inform or educate, remind or recall, teach skills, provide support, facilitate decision making, enable communication and enhance community ownership. These categories are broken down into 43 intervention types across three target groups: parents or soon-to-be-parents; communities, community

    M. G. Pereira


    Full Text Available No estado do Rio de Janeiro, destacam-se três feições geomorfológicas: as formações constituídas por rochas do Complexo Cristalino, expostas ou capeadas por seus produtos de alteração; os tabuleiros costeiros, compostos pelos sedimentos da Formação Barreiras, e, por último, as planícies aluvionares, que são formações quaternárias. As diferenças entre os materiais de origem e as classes de relevo e sua influência na formação dos solos têm constituído o tema principal dos estudos de genêse realizados no Rio de Janeiro. Este trabalho teve como objetivo avaliar o comportamento das formas extraíveis de ferro, Feo, Fed e Fes, e as relações entre elas em função do grau de pedogênese dos solos. Para estes solos, as formas de ferro e relações Fed/Fes e Feo/Fed expressaram variações na mineralogia do material de origem, grau de intemperismo dos solos e do material formador, ou classe de drenagem, mais do que a intensidade de pedogênese. Assim, as formas extraíveis de Fe e respectivas relações para avaliar o grau de pedogênese, nos solos do Rio de Janeiro, requerem uma interpretação conjunta das demais propriedades do solo, com ênfase para a morfologia e classes de drenagem.

    D. S. Rheinheimer


    Full Text Available A biomassa microbiana assume papel importante na reciclagem do fósforo em solos tropicais e subtropicais. Este trabalho teve por objetivo quantificar o teor de fósforo armazenado na biomassa microbiana em solos submetidos a diferentes métodos de preparo e sucessões de culturas. Para tal, foram utilizados quatro experimentos, instalados em diferentes locais no Rio Grande do Sul a partir de 1979, envolvendo métodos de preparo do solo e sucessões de culturas. Em 1997, coletaram-se amostras de solos nos sistemas plantio direto e cultivo convencional, com várias sucessões de culturas, em três camadas de solo. O fósforo acumulado na biomassa microbiana foi determinado por fumigação-extração. O fósforo na biomassa não diferiu entre os métodos de preparo do solo no Latossolo Vermelho Distroférrico típico, mas foi maior no sistema plantio direto em comparação ao cultivo convencional no Latossolo Vermelho Distrófico típico e Argissolo Vermelho Distrófico típico. O cultivo de diferentes plantas anuais não afetou os teores de fósforo microbiano. O fluxo anual de P através da biomassa microbiana variou de 8 a 22 mg dm-3 ano-1 e, no Argissolo Vermelho Distrófico típico, foi maior no sistema plantio direto do que no cultivo convencional.

    Directory of Open Access Journals (Sweden)



    Full Text Available Os objetivos deste trabalho foram verificar a adsorção de nitrato e identificar as propriedades do solo que mais influenciam este fenômeno, em um Latossolo Vermelho-Escuro, com 56% de argila, em Planaltina, DF. Em 1996 foram coletadas amostras de solo nas profundidades de 0-20, 20-40, 40-80, 80-100 cm, de um experimento com cinco anos de duração, em uma área de cerrado típico e em duas áreas cultivadas com soja e milho, onde o solo apresentava inversão de carga em profundidade. Também foram coletadas amostras em um solo sob cerradão, com carga elétrica líquida negativa em profundidade. A relação entre nitrato adsorvido e nitrato na solução foi descrita pela equação de Freundlich e as relações entre o nitrato adsorvido e algumas propriedades físico-químicas do solo foram estudadas por meio de regressões múltiplas. O nitrato adsorvido aumentou com a profundidade em todos os tratamentos. Esta adsorção foi maior nos solos sob cerrado e cerradão. O deltapH não afetou a adsorção de nitrato. A correlação entre nitrato adsorvido, matéria orgânica e sulfato extraível foi negativa. A adsorção de nitrato aumentou com a redução da matéria orgânica em profundidade e com a redução de sulfato extraível.

    Full Text Available A caracterização e análise geoquímica de solos permitem compreender os processos de migração, dispersão e concentração de elementos químicos no perfil, embasando a correlação dos atributos deles com as classes de solos formadas, o que possibilita inferências acerca das gêneses desses solos. Esta pesquisa teve por objetivos caracterizar e interpretar a composição geoquímica total de elementos maiores e menores em classes de solos representativas do Pantanal norte, na sub-região de Barão de Melgaço, Mato Grosso, Brasil. Foram selecionados 20 perfis das principais classes de solos do Pantanal e analisadas amostras dos horizontes A e B (ou C quanto à concentração de óxidos totais por espectrometria de fluorescência de raios-X, além das caracterizações física, química e mineralógica. Os solos subdividiram-se em dois tipos geoquímicos: um composto por textura arenosa a franco-arenosa com teores relativamente elevados de SiO2 e predominância de caulinita e quartzo, com menor teor de bases e elementos-traço; e outro composto por textura mais argilosa, geoquimicamente heterogêneos e com teores significativos de minerais 2:1, Al2O3, óxidos de Fe e Mn, bases e elementos-traço.

    Full Text Available BACKGROUND Unlike many other countries, only 19% of physicians remain independent or solo practitioners in the United States. This study seeks to determine if entry barriers to solo practice exist in physician services markets with a predominantly suburban patient base. Any entry barrier will play a critical role in a wide variety of competition and income-related issues in these markets. MATERIALS AND METHODS This study hypothesizes that substantial deterrence to entry is present in suburban settings where physician competition is typically much less than metropolitan areas. Information about their competitive position was obtained from solo primary care physicians (PCPs and specialists in southern New Jersey municipalities. Two-sample t - tests (α =0.05 ascertained whether the means differences of these two groups are statistically significant for the population from which they were sampled. Regression coefficients were computed for the magnitude of differences in barrier impact between samples. RESULTS Adapting the Orr model, E = ß0 e ß 1 (πp -π* e ß 2 Q . S ß 3 µ, to this study allowed us to estimate the overall height of entry barriers to suburban solo practice. The study finds that entry barriers tend to have moderate effects on PCPs, with the exception of legal and regulatory compliance which are just as burdensome to specialists. Risk and insurance, capital, advertising, research and development (R & D as well as market concentration are far more challenging to solo specialists mainly due to overuse of already costly tests, procedures, and medications by specialists for "defensive medicine," and heavy reliance on specialists by PCPs. Labor costs are associated with several barriers. CONCLUSION Despite their declining population, market entry (and presumably survival of solo physicians is not as straightforward of a phenomenon as conjectural and anecdotal evidence might suggest. Medical specialty offers an explanatory variable

    Full Text Available As substâncias húmicas (SH representam o principal reservatório de carbono orgânico total do solo (COT e sua partição entre diferentes frações de solubilidade em meio alcalino ou ácido pode guardar relação com o tipo de solo e manejo adotado. O objetivo deste trabalho foi comparar a partição das SHs, de acordo com profundidade, tipo de solo, bioma e uso do solo no Brasil. Revisou-se a literatura, incluindo teses, dissertações, artigos e resumos em anais de eventos, em busca de dados sobre o teor de COT, sua porcentagem como ácidos húmicos (AH, ácidos fúlvicos (AF e humina (HU e a razão AH/AF. Os dados foram estratificados por intervalos comparáveis de profundidades (0-5, 5-10, 0-20, 20-50, 50-100 e >100 cm, biomas (Mata Atlântica, Cerrado, Amazônia, Pampa e Caatinga, ordem de solo (Argissolo, Latossolo, Cambissolo, Planossolo, Neossolo, Gleissolo e Organossolo e principais usos do solo (florestas nativas, pastagem natural, pastagem plantada, eucalipto, culturas perenes e anuais. Os dados foram analisados por estatística descritiva, correlações de Spearman e análise de componentes principais (ACP. Nos Argissolos, Latossolos e Organossolos, a fração HU contribuiu com metade do COT, tendendo a diminuir em profundidade. Para Latossolos e Organossolos, a fração AF tendeu a aumentar em profundidade. Em Neossolos, a fração AH aumentou em profundidade, embora tenha diminuído em Gleissolos e Planossolos. A razão AH/AF geralmente diminui em profundidade. Pela ACP, não foi possível identificar um padrão de agrupamento das amostras em razão do tipo de bioma e uso do solo, sugerindo que a partição das SHs tem baixo potencial como indicador de efeitos do manejo ou condições ambientais, embora seja útil para discriminar processos de humificação em algumas ordens de solo.
