    Molecular targeting using ligands specific to disease markers has shown great promise for early detection and directed therapy. Bead-based combinatorial libraries have served as powerful tools for the discovery of novel targeting agents. Screening platforms employing magnetic capture have been used to achieve rapid and efficient identification of high-affinity ligands from one-bead-one-compound (OBOC) libraries. Traditional manual methodologies to isolate magnetized "hit" beads are tedious and lack accuracy, and existing instruments to expedite bead sorting tend to be costly and complex. Here, we describe the design and construction of a simple and inexpensive microfluidic magnetic sorting device using standard photolithography and soft lithography approaches to facilitate high-throughput isolation of magnetized positive hit beads from combinatorial libraries. We have demonstrated that the device is able to sort magnetized beads with superior accuracy compared to conventional manual sorting approaches. This chip offers a very convenient yet inexpensive alternative for screening OBOC libraries.

    One-bead-one-compound (OBOC) libraries provide a powerful tool for drug discovery as well as biomedical research. However, screening a large number of beads/compounds (>1 million) and rank ordering the initial hits (which are covalently attached to a solid support) according to their potencies still post significant technical challenges. In this work, we have integrated some of the latest technical advances from our own as well as other laboratories to develop a general methodology for rapidly screening large OBOC libraries. The methodology has been applied to synthesize and screen a cyclic peptide library that features: (1) spatially segregated beads containing cyclic peptides on the surface layer and linear encoding peptides in their interior; (2) rapid on-bead screening of the library (>1 million) by a multistage procedure (magnetic bead sorting, enzyme-linked assay, and fluorescence based screening); (3) selective release of cyclic peptides from single positive beads for solution-phase determination of their binding affinities; and (4) hit identification by partial Edman degradation/mass spectrometry (PED/MS). Screening of the library against protein phosphatase calcineurin (Cn) identified a series of cyclic peptides that bind to the substrate-docking site for nuclear factor of activated T cells (NFAT) with K(D) values of ∼1 μM. Further improvement of the affinity and specificity of these compounds may lead to a new class of immunosuppressive agents that are more selective and therefore less toxic than cyclosporine A and FK506.

    The increasing involvement of academic institutions and biotech companies in drug discovery calls for cost-effective methods to identify new bioactive molecules. Affinity-based on-bead screening of combinatorial one-bead one-compound libraries combines a split-mix synthesis design with a simple protein binding assay operating directly at the bead matrix. However, one bottleneck for academic scale on-bead screening is the unavailability of a cheap, automated, and robust screening platform that still provides a quantitative signal related to the amount of target protein binding to individual beads for hit bead ranking. Wide-field fluorescence microscopy has long been considered unsuitable due to significant broad spectrum autofluorescence of the library beads in conjunction with low detection sensitivity. Herein, we demonstrate how such a standard microscope equipped with LED-based excitation and a modern CMOS camera can be successfully used for selecting hit beads. We show that the autofluorescence issue can be overcome by an optical image subtraction approach that yields excellent signal-to-noise ratios for the detection of bead-associated target proteins. A polymer capillary attached to a semiautomated bead-picking device allows the operator to efficiently isolate individual hit beads in less than 20 s. The system can be used for ultrafast screening of >200,000 bead-bound compounds in 1.5 h, thereby making high-throughput screening accessible to a wider group within the scientific community.

    We report an analytical method to determine peptide loading of "one-bead one-compound" (OBOC) combinatorial peptide libraries at single-bead level. The quantification is based on a linear relationship between the amount of N-terminal amino groups on individual peptide beads and the intensity of Raman signal obtained from a specifically designed reporter labeled on amino groups. Confocal Raman spectroscopy was employed to characterize peptide loading of beads with defined peptide sequences and from OBOC combinatorial peptide libraries. Although amine loading of blank TentaGel beads was found to be uniform, peptide loading among beads of OBOC peptide libraries varied substantially, particularly for those libraries with long sequences. Construction of OBOC libraries can be monitored with this novel analytical technique so that synthetic conditions can be optimized for the preparation of high-quality OBOC peptide libraries. As the variability of peptide loading of individual library beads can significantly influence the screening results, quantitative information obtained by this method will allow us to gain insight into the complexity and challenge of OBOC library synthesis and screening.

  5. Identification of cancer specific ligands from one-bead one compound combinatorial libraries to develop theranostics agents against oral squamous cell carcinoma

    Yang, Frances Fan

    Background: Oral squamous cell carcinoma (OSCC) is one of the most prevalent disease worldwide. One-bead one-compound (OBOC) combinatorial technology is a powerful method to identify peptidomimetic ligands against a variety of receptors on cell surfaces. We therefore hypothesized that cancer specific ligands against OSCC might be identified and can be conjugated to optical dyes or nanocarriers to develop theranostic agents against OSCC. Material and methods: Different OSCC cell lines were incubated with OBOC libraries and beads with cell binding were sorted and then screened with normal human cells to identify peptide-beads binding to different OSCC cell lines but not binding to normal human cells. The molecular probes of OSCC were developed by biotinylating the carboxyl end of the ligands. OSCC theranostic agents were developed by decorating LLY13 with NPs and evaluated by using orthotopic bioluminescent oral cancer model. Results: Six OSCC specific ligands were discovered. Initial peptide-histochemistry study indicated that LLY12 and LLY13 were able to specifically detect OSCC cells grown on chamber slides at the concentration of 1 muM. In addition, LLY13 was found to penetrate into the OSCC cells and accumulate in the cytoplasm, and nucleus. After screened with a panel of integrin antibodies, only anti-alpha3 antibody was able to block most of OSCC cells binding to the LLY13 beads. OSCC theranostic agents developed using targeting LLY13 micelles (25+/- 4nm in diameter) were more efficient in binding to HSC-3 cancer cells compared to non-targeting micelles. Ex vivo images demonstrated that xenografts from the mice with targeting micelles appeared to have higher signals than the non-targeting groups. Conclusion: LLY13 has promising in vitro and in vivo targeting activity against OSCC. In addition, LLY13 is also able to penetrate into cancer cells via endocytosis. Initial study indicated that alpha3 integrin might partially be the corresponding receptor involved

    We report an approach to the high-throughput screening of asymmetric oxidation catalysts. The strategy is based on application of the one-bead-one-compound library approach, wherein each of our catalyst candidates is based on a peptide scaffold. For this purpose we rely on a recently developed catalytic cycle that employs an acid-peracid shuttle. In order to implement our approach, we developed a compatible linker and demonstrated that the library format is amenable to screening and sequencing of catalysts employing partial Edman degradation and MALDI mass spectrometry analysis. The system was applied to the discovery (and re-discovery) of catalysts for the enantioselective oxidation of a cyclohexene derivative. The system is now poised for application to unprecedented substrate classes for asymmetric oxidation reactions. PMID:21417485

    Mutation of isocitrate dehydrogenase 1 (IDH1) which is frequently found in certain cancers such as glioma, sarcoma and acute myeloid leukemia, has been proven to be a potent drug target for cancer therapy. In silico methodologies such as 3D-QSAR and molecular docking were performed to explore compounds with better mutant isocitrate dehydrogenase 1 (MIDH1) inhibitory activity using a series of 40 newly reported 1-hydroxypyridin-2-one compounds as MIDH1 inhibitors. The satisfactory CoMFA and CoMSIA models obtained after internal and external cross-validation gave q2 values of 0.691 and 0.535, r2 values of 0.984 and 0.936, respectively. 3D contour maps generated from CoMFA and CoMSIA along with the docking results provided information about the structural requirements for better MIDH1 inhibitory activity. Based on the structure-activity relationship, 17 new potent molecules with better predicted activity than the most active compound in the literature have been designed.

    Acute pancreatitis (AP) is a painful inflammatory disorder of the exocrine pancreas, ranking as the most common gastrointestinal reasons for hospitalization with no specific therapy currently. Diosgenyl saponins extracted from natural products and diosgenin or its derivatives have been shown to exert anti-inflammatory effects in various diseases. However, the therapeutic effects of diosgenyl saponins from Dioscorea zingiberensis C. H. Wright in AP have not yet been determined. Five compounds were extracted and screened for taurocholate-induced necrosis in mouse pancreatic acinar cells. Particularly, 26-O-β-d-glucopyranosyl-3β, 22α, 26-trihydroxy-25(R)-furosta-5-en-3-O-[α-L-rhamnopyranosyl-(1 → 4)]-β-d-glucopyranoside (compound 1) exhibited the best protective effects with no toxicity observed. Next, we showed compound 1 concentration-dependently inhibited necrotic cell death pathway activation and 2.5 mM compound 1 also prevented the loss of mitochondrial membrane potential, adenosine triphosphate production, and reactive oxygen species generation in mouse pancreatic acinar cells. Finally, we showed compound 1 protected against three clinically representative murine models of AP and significantly improved pancreatitis-associated acute lung injury. These data provide in vitro and in vivo evidence that one compound of diosgenyl saponins can be potential treatment for AP. This study suggests natural saponins may serve as fruitful sources for exploring/identifying potential therapies for inflammatory diseases. PMID:27779235

    2017-01-01

    We present a revised version of a coarse-grained model for RNA dynamics. In such approach, the description of nucleotides is reduced to single points that interact between them through a series of effective pair potentials that were obtained from an improved analysis of RNA structures from the Protein Data Bank. These interaction potentials are the main constituents of a Brownian dynamics simulation algorithm that allows to perform a variety of tasks by taking advantage of the reduced number of variables. Such tasks include the prediction of the three-dimensional configuration of a series of test molecules. Moreover, the model permits the inclusion of effective magnesium ions and the ends of the RNA chains can be pulled with an external force to study the process of unfolding. In spite of the simplicity of the model, we obtain a good agreement with the experimental results.

    Various methods have been developed independently to study the multifractality of measures in many different contexts. Although they all convey the same intuitive idea of giving a "dimension" to sets where a quantity scales similarly within a space, they are not necessarily equivalent on a more rigorous level. This review article aims at unifying the multifractal methodology by presenting the multifractal theoretical framework and principal practical methods, namely the moment method, the histogram method, multifractal detrended fluctuation analysis (MDFA) and modulus maxima wavelet transform (MMWT), with a comparative and interpretative eye.

  15. Methodological advances

    2004-06-01

    Full Text Available The study of population dynamics has long depended on methodological progress. Among many striking examples, continuous time models for populations structured in age (Sharpe & Lotka, 1911 were made possible by progress in the mathematics of integral equations. Therefore the relationship between population ecology and mathematical and statistical modelling in the broad sense raises a challenge in interdisciplinary research. After the impetus given in particular by Seber (1982, the regular biennial EURING conferences became a major vehicle to achieve this goal. It is thus not surprising that EURING 2003 included a session entitled “Methodological advances”. Even if at risk of heterogeneity in the topics covered and of overlap with other sessions, such a session was a logical way of ensuring that recent and exciting new developments were made available for discussion, further development by biometricians and use by population biologists. The topics covered included several to which full sessions were devoted at EURING 2000 (Anderson, 2001 such as: individual covariates, Bayesian methods, and multi–state models. Some other topics (heterogeneity models, exploited populations and integrated modelling had been addressed by contributed talks or posters. Their presence among “methodological advances”, as well as in other sessions of EURING 2003, was intended as a response to their rapid development and potential relevance to biological questions. We briefly review all talks here, including those not published in the proceedings. In the plenary talk, Pradel et al. (in prep. developed GOF tests for multi–state models. Until recently, the only goodness–of–fit procedures for multistate models were ad hoc, and non optimal, involving use of standard tests for single state models (Lebreton & Pradel, 2002. Pradel et al. (2003 proposed a general approach based in particular on mixtures of multinomial distributions. Pradel et al. (in prep. showed

    Journal article about Reliability Centered Maintenance (RCM) methodologies used by United Space Alliance, LLC (USA) in support of the Space Shuttle Program at Kennedy Space Center. The USA Reliability Centered Maintenance program differs from traditional RCM programs because various methodologies are utilized to take advantage of their respective strengths for each application. Based on operational experience, USA has customized the traditional RCM methodology into a streamlined lean logic path and has implemented the use of statistical tools to drive the process. USA RCM has integrated many of the L6S tools into both RCM methodologies. The tools utilized in the Measure, Analyze, and Improve phases of a Lean Six Sigma project lend themselves to application in the RCM process. All USA RCM methodologies meet the requirements defined in SAE JA 1011, Evaluation Criteria for Reliability-Centered Maintenance (RCM) Processes. The proposed article explores these methodologies.

    Full Text Available The implementation of a language policy is crucially associated with questions of methodology. This paper explores approaches to language policy, approaches to methodology and the impact that these have on language teaching practice. Language policies can influence decisions about teaching methodologies either directly, by making explicit recommendations about the methods to be used in classroom practice, or indirectly, through the conceptualisation of language leaming which underlies the policy. It can be argued that all language policies have the potential to influence teaching methodologies indirectly and that those policies which have explicit recommendations about methodology are actually functioning of two levels. This allows for the possibility of conflict between the direct and indirect dimensions of the policy which results from an inconsistency between the explicitly recommended methodology and the underlying conceptualisation of language teaching and learning which informs the policy.

    The fallout from a nuclear explosion has the potential to injure or kill 100,000 or more people through exposure to external gamma (fallout) radiation. Existing buildings can reduce radiation exposure by placing material between fallout particles and exposed people. Lawrence Livermore National Laboratory was tasked with developing an operationally feasible methodology that could improve fallout casualty estimates. The methodology, called a Regional Shelter Analysis, combines the fallout protection that existing buildings provide civilian populations with the distribution of people in various locations. The Regional Shelter Analysis method allows the consideration of (a) multiple building types and locations within buildings, (b) country specific estimates, (c) population posture (e.g., unwarned vs. minimally warned), and (d) the time of day (e.g., night vs. day). The protection estimates can be combined with fallout predictions (or measurements) to (a) provide a more accurate assessment of exposure and injury and (b) evaluate the effectiveness of various casualty mitigation strategies. This report describes the Regional Shelter Analysis methodology, highlights key operational aspects (including demonstrating that the methodology is compatible with current tools), illustrates how to implement the methodology, and provides suggestions for future work.

These need to be objective, reliable and in a repeatable format. Hence, the understanding of the basic aspects of methodology is essential for any researcher. This is a narrative review and focuses on various aspects of the methodology for conduct of a clinical research. The relevant keywords were used for literature search from various databases and from bibliographies of the articles.

    Full Text Available Understanding the nondualistic nature of mindfulness is a complex and challenging task particularly when most clinical psychology draws from Western methodologies and methods. In this article, we argue that the integration of philosophical hermeneutics with Eastern philosophy and practices may provide a methodology and methods to research mindfulness practice. Mindfulness hermeneutics brings together the nondualistically aligned Western philosophies of Heidegger and Gadamer and selected Eastern philosophies and practices in an effort to bridge the gap between these differing worldviews. Based on the following: (1 fusion of horizons, (2 being in a hermeneutic circle, (3 understanding as intrinsic to awareness, and (4 the ongoing practice of meditation, a mindfulness hermeneutic approach was used to illuminate deeper understandings of mindfulness practice in ways that are congruent with its underpinning philosophies.

  3. Soft Systems Methodology

    Science.gov (United States)

    Checkland, Peter; Poulter, John

    Soft systems methodology (SSM) is an approach for tackling problematical, messy situations of all kinds. It is an action-oriented process of inquiry into problematic situations in which users learn their way from finding out about the situation, to taking action to improve it. The learning emerges via an organised process in which the situation is explored using a set of models of purposeful action (each built to encapsulate a single worldview) as intellectual devices, or tools, to inform and structure discussion about a situation and how it might be improved. This paper, written by the original developer Peter Checkland and practitioner John Poulter, gives a clear and concise account of the approach that covers SSM's specific techniques, the learning cycle process of the methodology and the craft skills which practitioners develop. This concise but theoretically robust account nevertheless includes the fundamental concepts, techniques, core tenets described through a wide range of settings.

    Tobacco documents research has developed into a thriving academic enterprise since its inception in 1995. The technology supporting tobacco documents archiving, searching and retrieval has improved greatly since that time, and consequently tobacco documents researchers have considerably more access to resources than was the case when researchers had to travel to physical archives and/or electronically search poorly and incompletely indexed documents. The authors of the papers presented in this supplement all followed the same basic research methodology. Rather than leave the reader of the supplement to read the same discussion of methods in each individual paper, presented here is an overview of the methods all authors followed. In the individual articles that follow in this supplement, the authors present the additional methodological information specific to their topics. This brief discussion also highlights technological capabilities in the Legacy Tobacco Documents Library and updates methods for organising internal tobacco documents data and findings.

  9. Differing antidepressant maintenance methodologies.

    Safer, Daniel J

    2017-10-01

    The principle evidence that antidepressant medication (ADM) is an effective maintenance treatment for adults with major depressive disorder (MDD) is from placebo substitution trials. These trials enter responders from ADM efficacy trials into randomized, double-blind placebo-controlled (RDBPC) effectiveness trials to measure the rate of MDD relapse over time. However, other randomized maintenance trial methodologies merit consideration and comparison. A systematic review of ADM randomized maintenance trials included research reports from multiple databases. Relapse rate was the main effectiveness outcome assessed. Five ADM randomized maintenance methodologies for MDD responders are described and compared for outcome. These effectiveness trials include: placebo-substitution, ADM/placebo extension, ADM extension, ADM vs. psychotherapy, and treatment as usual. The placebo-substitution trials for those abruptly switched to placebo resulted in unusually high (46%) rates of relapse over 6-12months, twice the continuing ADM rate. These trials were characterized by selective screening, high attrition, an anxious anticipation of a switch to placebo, and a risk of drug withdrawal symptoms. Selectively screened ADM efficacy responders who entered into 4-12month extension trials experienced relapse rates averaging ~10% with a low attrition rate. Non-industry sponsored randomized trials of adults with multiple prior MDD episodes who were treated with ADM maintenance for 1-2years experienced relapse rates averaging 40%. Placebo substitution trial methodology represents only one approach to assess ADM maintenance. Antidepressant maintenance research for adults with MDD should be evaluated for industry sponsorship, attrition, the impact of the switch to placebo, and major relapse differences in MDD subpopulations.

    2009-10-01

    Full Text Available This paper scrutinizes the recent proposal made by Lassiter (2008 that the dichotomy between Chomskyan internalism and Dummett-type externalism is misguided and should be overcome by an approach that incorporates sociolinguistic concepts such as speakers’ dispositions to defer. We argue that Lassiter’s arguments are flawed and based on a serious misunder-standing of the internalist approach to the study of natural language, failing to appreciate its methodological nature and conclude that Lassiter’s socio-linguistic approach is just another instance of externalist attempts with little hope of scientific achievement.

Actually, the great emphasis is given to the production of rapid techniques of data collection, the difference between consumers and trained panel is obscured and the role of sensory methodologists is to prepare the ways for evaluation, by which a lay panel (consumers can achieve identical results as a trained panel. Currently, there are several conventional methods of sensory evaluation of food (ISO standards, but more sensory laboratories are developing methodologies that are not strict enough in the selection of evaluators, their mechanism is easily understandable and the results are easily interpretable.

Einstein characterized his work as a theory of principle and reasoned that beyond kinematics, the 1905 heuristic relativity principle could offer new connections between non-kinematical concepts. 2. Einstein's creativity and inventiveness and process of thinking; invention or discovery. 3. Einstein considered his best friend Michele Besso as a sounding board and his class-mate from the Polytechnic Marcel Grossman, as his active partner. Yet, Einstein wrote to Arnold Sommerfeld that Grossman will never claim to be considered a co-discoverer of the Einstein-Grossmann theory. He only helped in guiding Einstein through the mathematical literature, but contributed nothing of substance to the results of the theory. Hence, Einstein neither considered Besso or Grossmann as co-discoverers of the relativity theory which he invented.

    2012-01-01

    Qualitative nurse researchers are required to make deliberate and sometimes complex methodological decisions about their work. Methodology in qualitative research is a comprehensive approach in which theory (ideas) and method (doing) are brought into close alignment. It can be difficult, at times, to understand the concept of methodology. The purpose of this research column is to: (1) define qualitative methodology; (2) illuminate the relationship between epistemology, ontology and methodology; (3) explicate the connection between theory and method in qualitative research design; and 4) highlight relevant examples of methodological decisions made within cardiovascular nursing research. Although there is no "one set way" to do qualitative research, all qualitative researchers should account for the choices they make throughout the research process and articulate their methodological decision-making along the way.

  20. Engineering radioecology: Methodological considerations

    1995-12-31

    The term ``radioecology`` has been widely recognized in scientific and technical societies. At the same time, this scientific school (radioecology) does not have a precise/generally acknowledged structure, unified methodical basis, fixed subjects of investigation, etc. In other words, radioecology is a vast, important but rather amorphous conglomerate of various ideas, amalgamated mostly by their involvement in biospheric effects of ionizing radiation and some conceptual stereotypes. This paradox was acceptable up to a certain time. However, with the termination of the Cold War and because of remarkable political changes in the world, it has become possible to convert the problem of environmental restoration from the scientific sphere in particularly practical terms. Already the first steps clearly showed an imperfection of existing technologies, managerial and regulatory schemes; lack of qualified specialists, relevant methods and techniques; uncertainties in methodology of decision-making, etc. Thus, building up (or maybe, structuring) of special scientific and technological basis, which the authors call ``engineering radioecology``, seems to be an important task. In this paper they endeavored to substantiate the last thesis and to suggest some preliminary ideas concerning the subject matter of engineering radioecology.

  1. Cancer cytogenetics: methodology revisited.

    Science.gov (United States)

    Wan, Thomas S K

    2014-11-01

    The Philadelphia chromosome was the first genetic abnormality discovered in cancer (in 1960), and it was found to be consistently associated with CML. The description of the Philadelphia chromosome ushered in a new era in the field of cancer cytogenetics. Accumulating genetic data have been shown to be intimately associated with the diagnosis and prognosis of neoplasms; thus, karyotyping is now considered a mandatory investigation for all newly diagnosed leukemias. The development of FISH in the 1980s overcame many of the drawbacks of assessing the genetic alterations in cancer cells by karyotyping. Karyotyping of cancer cells remains the gold standard since it provides a global analysis of the abnormalities in the entire genome of a single cell. However, subsequent methodological advances in molecular cytogenetics based on the principle of FISH that were initiated in the early 1990s have greatly enhanced the efficiency and accuracy of karyotype analysis by marrying conventional cytogenetics with molecular technologies. In this review, the development, current utilization, and technical pitfalls of both the conventional and molecular cytogenetics approaches used for cancer diagnosis over the past five decades will be discussed.

    The subject of this symposium is naproxen, a new drug that resulted from an investigation to find a superior anti-inflammatory agent. It was synthesized by Harrison et al. in 1970 at the Syntex Institute of Organic Chemistry and Biological Sciences. How can we chart the evolution of this or any other drug? Three steps are necessary: first, chemical studies (synthesis, analysis); second, animal pharmacology; third, human pharmacology. The last step can additionally be divided into four phases: metabolism and toxicology of the drug in normal volunteers; dose titration and initial clinical trials with sick subjects (pharmacometry); confirmatory clinical trials when the drug is accepted on the market and revaluation (familiarization trials). To discover the truth about naproxen, we must all participate actively with a critical mind, following the principles of scientific methodology. We shall find that the papers to be presented today all deal with the third step in the evaluation process--clinical pharmacology. It is quite evident that the final and most decisive test must be aimed at the most valuable target: the human being. The end product of this day's work for each of us should be the formation of an opinion based on solid scientific proofs. And let us hope that we will all enjoy fulfilling the symposium in its entire etymological meaning this evening. In vino veritas.

    2005-06-01

    The glycaemic index (GI) concept was originally introduced to classify different sources of carbohydrate (CHO)-rich foods, usually having an energy content of >80 % from CHO, to their effect on post-meal glycaemia. It was assumed to apply to foods that primarily deliver available CHO, causing hyperglycaemia. Low-GI foods were classified as being digested and absorbed slowly and high-GI foods as being rapidly digested and absorbed, resulting in different glycaemic responses. Low-GI foods were found to induce benefits on certain risk factors for CVD and diabetes. Accordingly it has been proposed that GI classification of foods and drinks could be useful to help consumers make 'healthy food choices' within specific food groups. Classification of foods according to their impact on blood glucose responses requires a standardised way of measuring such responses. The present review discusses the most relevant methodological considerations and highlights specific recommendations regarding number of subjects, sex, subject status, inclusion and exclusion criteria, pre-test conditions, CHO test dose, blood sampling procedures, sampling times, test randomisation and calculation of glycaemic response area under the curve. All together, these technical recommendations will help to implement or reinforce measurement of GI in laboratories and help to ensure quality of results. Since there is current international interest in alternative ways of expressing glycaemic responses to foods, some of these methods are discussed.

    Searching for life in astromaterials to be delivered from the future missions to extraterrestrial bodies is undoubtedly related to studies of the properties and signatures of living microbial cells and microfossils on Earth. As model terrestrial analogs of Martian polar subsurface layers are often regarded the Antarctic glacier and Earth permafrost habitats where alive microbial cells preserved viability for millennia years due to entering the anabiotic state. For the future findings of viable microorganisms in samples from extraterrestrial objects, it is important to use a combined methodology that includes classical microbiological methods, plating onto nutrient media, direct epifluorescence and electron microscopy examinations, detection of the elemental composition of cells, radiolabeling techniques, PCR and FISH methods. Of great importance is to ensure authenticity of microorganisms (if any in studied samples) and to standardize the protocols used to minimize a risk of external contamination. Although the convincing evidence of extraterrestrial microbial life will may come from the discovery of living cells in astromaterials, biomorphs and microfossils must also be regarded as a target in search of life evidence bearing in mind a scenario that alive microorganisms had not be preserved and underwent mineralization. Under the laboratory conditions, processes that accompanied fossilization of cyanobacteria were reconstructed, and artificially produced cyanobacterial stromatolites resembles by their morphological properties those found in natural Earth habitats. Regarding the vital importance of distinguishing between biogenic and abiogenic signatures and between living and fossil microorganisms in analyzed samples, it is worthwhile to use some previously developed approaches based on electron microscopy examinations and analysis of elemental composition of biomorphs in situ and comparison with the analogous data obtained for laboratory microbial cultures and

    2010-09-01

    Full Text Available Abstract Background Scoping studies are an increasingly popular approach to reviewing health research evidence. In 2005, Arksey and O'Malley published the first methodological framework for conducting scoping studies. While this framework provides an excellent foundation for scoping study methodology, further clarifying and enhancing this framework will help support the consistency with which authors undertake and report scoping studies and may encourage researchers and clinicians to engage in this process. Discussion We build upon our experiences conducting three scoping studies using the Arksey and O'Malley methodology to propose recommendations that clarify and enhance each stage of the framework. Recommendations include: clarifying and linking the purpose and research question (stage one; balancing feasibility with breadth and comprehensiveness of the scoping process (stage two; using an iterative team approach to selecting studies (stage three and extracting data (stage four; incorporating a numerical summary and qualitative thematic analysis, reporting results, and considering the implications of study findings to policy, practice, or research (stage five; and incorporating consultation with stakeholders as a required knowledge translation component of scoping study methodology (stage six. Lastly, we propose additional considerations for scoping study methodology in order to support the advancement, application and relevance of scoping studies in health research. Summary Specific recommendations to clarify and enhance this methodology are outlined for each stage of the Arksey and O'Malley framework. Continued debate and development about scoping study methodology will help to maximize the usefulness and rigor of scoping study findings within healthcare research and practice.

    This methodology serves to define a system for effective prioritization of efforts required to develop replacement technologies mandated by imposed and forecast legislation. The methodology used is a semi quantitative approach derived from quality function deployment techniques (QFD Matrix). QFD is a conceptual map that provides a method of transforming customer wants and needs into quantitative engineering terms. This methodology aims to weight the full environmental, cost, safety, reliability, and programmatic implications of replacement technology development to allow appropriate identification of viable candidates and programmatic alternatives.

  8. Q methodology in health economics.

    Science.gov (United States)

    Baker, Rachel; Thompson, Carl; Mannion, Russell

    2006-01-01

    The recognition that health economists need to understand the meaning of data if they are to adequately understand research findings which challenge conventional economic theory has led to the growth of qualitative modes of enquiry in health economics. The use of qualitative methods of exploration and description alongside quantitative techniques gives rise to a number of epistemological, ontological and methodological challenges: difficulties in accounting for subjectivity in choices, the need for rigour and transparency in method, and problems of disciplinary acceptability to health economists. Q methodology is introduced as a means of overcoming some of these challenges. We argue that Q offers a means of exploring subjectivity, beliefs and values while retaining the transparency, rigour and mathematical underpinnings of quantitative techniques. The various stages of Q methodological enquiry are outlined alongside potential areas of application in health economics, before discussing the strengths and limitations of the approach. We conclude that Q methodology is a useful addition to economists' methodological armoury and one that merits further consideration and evaluation in the study of health services.

  10. The NLC Software Requirements Methodology

    Energy Technology Data Exchange (ETDEWEB)

    Shoaee, Hamid

    2002-08-20

    We describe the software requirements and development methodology developed for the NLC control system. Given the longevity of that project, and the likely geographical distribution of the collaborating engineers, the planned requirements management process is somewhat more formal than the norm in high energy physics projects. The short term goals of the requirements process are to accurately estimate costs, to decompose the problem, and to determine likely technologies. The long term goal is to enable a smooth transition from high level functional requirements to specific subsystem and component requirements for individual programmers, and to support distributed development. The methodology covers both ends of that life cycle. It covers both the analytical and documentary tools for software engineering, and project management support. This paper introduces the methodology, which is fully described in [1].

    This paper considers how the integral theory model of Nancy Davis and Laurie Callihan might be enacted using a different qualitative methodology, in this case the narrative methodology. The focus of narrative research is shown to be on `what meaning is being made' rather than `what is happening here' (quadrant 2 rather than quadrant 1). It is suggested that in using the integral theory model, a qualitative research project focuses primarily on one quadrant and is enhanced by approaches suggested in the other quadrants.

  20. Unattended Monitoring System Design Methodology

    Energy Technology Data Exchange (ETDEWEB)

    Drayer, D.D.; DeLand, S.M.; Harmon, C.D.; Matter, J.C.; Martinez, R.L.; Smith, J.D.

    1999-07-08

    A methodology for designing Unattended Monitoring Systems starting at a systems level has been developed at Sandia National Laboratories. This proven methodology provides a template that describes the process for selecting and applying appropriate technologies to meet unattended system requirements, as well as providing a framework for development of both training courses and workshops associated with unattended monitoring. The design and implementation of unattended monitoring systems is generally intended to respond to some form of policy based requirements resulting from international agreements or domestic regulations. Once the monitoring requirements are established, a review of the associated process and its related facilities enables identification of strategic monitoring locations and development of a conceptual system design. The detailed design effort results in the definition of detection components as well as the supporting communications network and data management scheme. The data analyses then enables a coherent display of the knowledge generated during the monitoring effort. The resultant knowledge is then compared to the original system objectives to ensure that the design adequately addresses the fundamental principles stated in the policy agreements. Implementation of this design methodology will ensure that comprehensive unattended monitoring system designs provide appropriate answers to those critical questions imposed by specific agreements or regulations. This paper describes the main features of the methodology and discusses how it can be applied in real world situations.

    Full Text Available The article deals with the investigation of theoretical and methodological principles of situational analysis. The necessity of situational analysis is proved in modern conditions. The notion “situational analysis” is determined. We have concluded that situational analysis is a continuous system study which purpose is to identify dangerous situation signs, to evaluate comprehensively such signs influenced by a system of objective and subjective factors, to search for motivated targeted actions used to eliminate adverse effects of the exposure of the system to the situation now and in the future and to develop the managerial actions needed to bring the system back to norm. It is developed a methodological approach to the situational analysis, its goal is substantiated, proved the expediency of diagnostic, evaluative and searching functions in the process of situational analysis. The basic methodological elements of the situational analysis are grounded. The substantiation of the principal methodological elements of system analysis will enable the analyst to develop adaptive methods able to take into account the peculiar features of a unique object which is a situation that has emerged in a complex system, to diagnose such situation and subject it to system and in-depth analysis, to identify risks opportunities, to make timely management decisions as required by a particular period.

    2016-02-01

    NLRP3 inflammasome is a key component of the inflammatory process and its dysregulation contributes to IBD for its ability to induce IL-1β release. Previously, we reported that a novel small molecular activator of Nrf2, 3-(2-oxo-2-phenylethylidene)-2,3,6,7-tetrahydro-1H-pyrazino-[2,1-a]isoquinolin-4(11bH)-one (compound 1) can prevent the development of colorectal adenomas in AOM-DSS models. Here we further investigated the anti-inflammatory effect of compound 1 in DSS-induced colitis in C57BL/6 and NLRP3(-/-) mice, and revealed the possible modulation by compound 1 of NLRP3 inflammasome-mediated IL-1β release from macrophages. In C57BL/6 mice, oral administration of compound 1 significantly attenuated DSS-induced colonic pathological damage, remarkably inhibited inflammatory cells infiltration and decreased myeloperoxidase (MPO) and IL-1β secretion in colons. In contrast, mice deficient for NLRP3 were less sensitive to DSS-induced acute colitis, and compound 1 treatment exerted no protective effect on DSS-induced intestinal inflammation in NLRP3(-/-) mice. The protective effect of compound 1 may be attributed to its inhibition of NLRP3 inflammasome and Nrf2 activation in colons. Furthermore, compound 1, as a small molecular activator of Nrf2, significantly inhibited NLRP3 inflammasome activation in both THP-1 derived macrophages and bone-marrow derived macrophages, as indicated by reduced expression of NLRP3 and cleaved caspase-1, and lowered IL-1β secretion. Finally, compound 1-induced NLRP3 inflammasome inhibition is through blocking NLRP3 priming step and dependent on Nrf2 activation. Taken together, our findings demonstrate that compound 1 might be a potential agent for the treatment of IBD by targeting Nrf2 and NLRP3 inflammasome.

    Since the introduction of a design methodology for Dutch banknotes, the quality of Dutch paper currency has improved in more than one way. The methodology is question provides for (i) a design policy, which helps fix clear objectives; (ii) design management, to ensure a smooth cooperation between the graphic designer, printer, papermaker an central bank, (iii) a program of requirements, a banknote development guideline for all parties involved. This systematic approach enables an objective selection of design proposals, including security features. Furthermore, the project manager obtains regular feedback from the public by conducting market surveys. Each new design of a Netherlands Guilder banknote issued by the Nederlandsche Bank of the past 50 years has been an improvement on its predecessor in terms of value recognition, security and durability.

    2014-07-01

    The TRACG model simulates a multi-dimensional vessel and contains a flexible modular structure with control system capability. TRACG has undergone benchmarking qualifications with extensive testing and actual plant data. This best estimate methodology has been used widely in BWR safety analyses as well as in the qualification of the GEH advanced BWR designs. The application of TRACG methodology for loss of coolant accident (LOCA) analyses will provide realistic fuel bundle thermal responses. By taking advantage of these additional margins, the utility owner can justify the optimization of plant-specific emergency core cooling system performance requirements and justify certain equipment declared inoperable. The resulting benefits are improved plant capacity and reliability and improved equipment reliability and lifetime. (Author)

  4. Energy Efficiency Indicators Methodology Booklet

    Energy Technology Data Exchange (ETDEWEB)

    Sathaye, Jayant; Price, Lynn; McNeil, Michael; de la rue du Can, Stephane

    2010-05-01

    This Methodology Booklet provides a comprehensive review and methodology guiding principles for constructing energy efficiency indicators, with illustrative examples of application to individual countries. It reviews work done by international agencies and national government in constructing meaningful energy efficiency indicators that help policy makers to assess changes in energy efficiency over time. Building on past OECD experience and best practices, and the knowledge of these countries' institutions, relevant sources of information to construct an energy indicator database are identified. A framework based on levels of hierarchy of indicators -- spanning from aggregate, macro level to disaggregated end-use level metrics -- is presented to help shape the understanding of assessing energy efficiency. In each sector of activity: industry, commercial, residential, agriculture and transport, indicators are presented and recommendations to distinguish the different factors affecting energy use are highlighted. The methodology booklet addresses specifically issues that are relevant to developing indicators where activity is a major factor driving energy demand. A companion spreadsheet tool is available upon request.

  5. Methodology for ranking restoration options

    1999-04-01

    The work described in this report has been performed as a part of the RESTRAT Project FI4P-CT95-0021a (PL 950128) co-funded by the Nuclear Fission Safety Programme of the European Commission. The RESTRAT project has the overall objective of developing generic methodologies for ranking restoration techniques as a function of contamination and site characteristics. The project includes analyses of existing remediation methodologies and contaminated sites, and is structured in the following steps: characterisation of relevant contaminated sites; identification and characterisation of relevant restoration techniques; assessment of the radiological impact; development and application of a selection methodology for restoration options; formulation of generic conclusions and development of a manual. The project is intended to apply to situations in which sites with nuclear installations have been contaminated with radioactive materials as a result of the operation of these installations. The areas considered for remedial measures include contaminated land areas, rivers and sediments in rivers, lakes, and sea areas. Five contaminated European sites have been studied. Various remedial measures have been envisaged with respect to the optimisation of the protection of the populations being exposed to the radionuclides at the sites. Cost-benefit analysis and multi-attribute utility analysis have been applied for optimisation. Health, economic and social attributes have been included and weighting factors for the different attributes have been determined by the use of scaling constants. (au)

  6. Methodology for astronaut reconditioning research.

    Beard, David J; Cook, Jonathan A

    2017-01-01

    Space medicine offers some unique challenges, especially in terms of research methodology. A specific challenge for astronaut reconditioning involves identification of what aspects of terrestrial research methodology hold and which require modification. This paper reviews this area and presents appropriate solutions where possible. It is concluded that spaceflight rehabilitation research should remain question/problem driven and is broadly similar to the terrestrial equivalent on small populations, such as rare diseases and various sports. Astronauts and Medical Operations personnel should be involved at all levels to ensure feasibility of research protocols. There is room for creative and hybrid methodology but careful systematic observation is likely to be more achievable and fruitful than complex trial based comparisons. Multi-space agency collaboration will be critical to pool data from small groups of astronauts with the accepted use of standardised outcome measures across all agencies. Systematic reviews will be an essential component. Most limitations relate to the inherent small sample size available for human spaceflight research. Early adoption of a co-operative model for spaceflight rehabilitation research is therefore advised.

  7. Software engineering methodologies and tools

    1993-01-01

    Over the years many engineering disciplines have developed, including chemical, electronic, etc. Common to all engineering disciplines is the use of rigor, models, metrics, and predefined methodologies. Recently, a new engineering discipline has appeared on the scene, called software engineering. For over thirty years computer software has been developed and the track record has not been good. Software development projects often miss schedules, are over budget, do not give the user what is wanted, and produce defects. One estimate is there are one to three defects per 1000 lines of deployed code. More and more systems are requiring larger and more complex software for support. As this requirement grows, the software development problems grow exponentially. It is believed that software quality can be improved by applying engineering principles. Another compelling reason to bring the engineering disciplines to software development is productivity. It has been estimated that productivity of producing software has only increased one to two percent a year in the last thirty years. Ironically, the computer and its software have contributed significantly to the industry-wide productivity, but computer professionals have done a poor job of using the computer to do their job. Engineering disciplines and methodologies are now emerging supported by software tools that address the problems of software development. This paper addresses some of the current software engineering methodologies as a backdrop for the general evaluation of computer assisted software engineering (CASE) tools from actual installation of and experimentation with some specific tools.

    Event Tree(ET)/Fault Tree(FT) are significant methodology in Probabilistic Safety Assessment(PSA) for Nuclear Power Plants(NPPs). ET/FT methodology has the advantage for users to be able to easily learn and model. It enables better communication between engineers engaged in the same field. However, conventional methodologies are difficult to cope with the dynamic behavior (e.g. operation mode changes or sequence-dependent failure) and integrated situation of mechanical failure and human errors. Meanwhile, new possibilities are coming for the improved PSA by virtue of the dramatic development on digital hardware, software, information technology, and data analysis.. More specifically, the computing environment has been greatly improved with being compared to the past, so we are able to conduct risk analysis with the large amount of data actually available. One method which can take the technological advantages aforementioned should be the dynamic PSA such that conventional ET/FT can have time- and condition-dependent behaviors in accident scenarios. In this paper, we investigated the various enabling techniques for the dynamic PSA. Even though its history and academic achievement was great, it seems less interesting from industrial and regulatory viewpoint. Authors expect this can contribute to better understanding of dynamic PSA in terms of algorithm, practice, and applicability. In paper, the overview for the dynamic PSA was conducted. Most of methodologies share similar concepts. Among them, DDET seems a backbone for most of methodologies since it can be applied to large problems. The common characteristics sharing the concept of DDET are as follows: • Both deterministic and stochastic approaches • Improves the identification of PSA success criteria • Helps to limit detrimental effects of sequence binning (normally adopted in PSA) • Helps to avoid defining non-optimal success criteria that may distort the risk • Framework for comprehensively considering

    Full Text Available Comprehensive System of Rorschach interpretation is considered as nomotetic system that makes possible using of projective method in research projects. However, research use of Rorschach method besides of appropriate knowledge of assign procedures and interpretation rules, means a knowledge of specific methodological issues. The Rorschach indicators are nor independent, as they are a part of specific net, so in some research it is necessary to control basic variables not to get artifacts in our research. This is basically relied on researches where we compare groups, as well as in normative studies where through cross-cultural we compare Rorschach indicators. .

    This paper introduces feminist methodologies in the context of engineering education research. It builds upon other recent methodology articles in engineering education journals and presents feminist research methodologies as a concrete engineering education setting in which to explore the connections between epistemology, methodology and theory. The paper begins with a literature review that covers a broad range of topics featured in the literature on feminist methodologies. Next, data from interviews with engineering educators and researchers who have engaged with feminist methodologies are presented. The ways in which feminist methodologies shape their research topics, questions, frameworks of analysis, methods, practices and reporting are each discussed. The challenges and barriers they have faced are then discussed. Finally, the benefits of further and broader engagement with feminist methodologies within the engineering education community are identified.

    Mirela GHEORGHE

    2010-01-01

    Full Text Available The continuous development of the new IT technologies was followed up by a rapid integration of them at the organization level. The management of the organizations face a new challenge: structural redefinition of the IT component in order to create plus value and to minimize IT risks through an efficient management of all IT resources of the organization. These changes have had a great impact on the governance of the IT component. The paper proposes an audit methodology of the IT Governance at the organization level. From this point of view the developed audit strategy is a strategy based on risks to enable IT auditor to study from the best angle efficiency and effectiveness of the IT Governance structure. The evaluation of the risks associated with IT Governance is a key process in planning the audit mission which will allow the identification of the segments with increased risks. With now ambition for completeness, the proposed methodology provides the auditor a useful tool in the accomplishment of his mission.

  18. Methodological issues in grounded theory.

    Science.gov (United States)

    Cutcliffe, J R

    2000-06-01

    Examination of the qualitative methodological literature shows that there appear to be conflicting opinions and unresolved issues regarding the nature and process of grounded theory. Researchers proposing to utilize this method would therefore be wise to consider these conflicting opinions. This paper therefore identifies and attempts to address four key issues, namely, sampling, creativity and reflexivity, the use of literature, and precision within grounded theory. The following recommendations are made. When utilizing a grounded method researchers need to consider their research question, clarify what level of theory is likely to be induced from their study, and then decide when they intend to access and introduce the second body of literature. They should acknowledge that in the early stages of data collection, some purposeful sampling appears to occur. In their search for conceptually dense theory, grounded theory researchers may wish to free themselves from the constraints that limit their use of creativity and tacit knowledge. Furthermore, the interests of researchers might be served by attention to issues of precision including, avoiding method slurring, ensuring theoretical coding occurs, and using predominantly one method of grounded theory while explaining and describing any deviation away from this chosen method. Such mindfulness and the resulting methodological rigour is likely to increase the overall quality of the inquiry and enhance the credibility of the findings.

  2. Methodology for Benchmarking IPsec Gateways

    Directory of Open Access Journals (Sweden)

    Adam Tisovský

    2012-08-01

    Full Text Available The paper analyses forwarding performance of IPsec gateway over the rage of offered loads. It focuses on the forwarding rate and packet loss particularly at the gateway’s performance peak and at the state of gateway’s overload. It explains possible performance degradation when the gateway is overloaded by excessive offered load. The paper further evaluates different approaches for obtaining forwarding performance parameters – a widely used throughput described in RFC 1242, maximum forwarding rate with zero packet loss and us proposed equilibrium throughput. According to our observations equilibrium throughput might be the most universal parameter for benchmarking security gateways as the others may be dependent on the duration of test trials. Employing equilibrium throughput would also greatly shorten the time required for benchmarking. Lastly, the paper presents methodology and a hybrid step/binary search algorithm for obtaining value of equilibrium throughput.

    Full Text Available Participatory research projects incorporating non-traditional, creative, and qualitative methodologies can produce results which are unexpected or divergent from original research proposals. These results are highly meaningful, yet challenging to express to an audience when the expectation is to write the findings in a linear and traditional format, such as in a graduate thesis. Within this article, we use an autoethnographic approach to describe our experiences with ethnodrama, from our perspectives as a graduate student and supervisor. We focus on a planned breast cancer ethnodrama pilot project, which developed into a healing yoga program instead. We question the traditional notion of successful research as being a linear, straightforward process. In doing so, we hope to create dialogue and support mentorship which acknowledges the "messiness" of research projects. We also assert that there is a need to embrace non-traditional methods for disseminating our "messy" research outcomes.

  4. Methodology for flammable gas evaluations

    Energy Technology Data Exchange (ETDEWEB)

    Hopkins, J.D., Westinghouse Hanford

    1996-06-12

    There are 177 radioactive waste storage tanks at the Hanford Site. The waste generates flammable gases. The waste releases gas continuously, but in some tanks the waste has shown a tendency to trap these flammable gases. When enough gas is trapped in a tank`s waste matrix, it may be released in a way that renders part or all of the tank atmosphere flammable for a period of time. Tanks must be evaluated against previously defined criteria to determine whether they can present a flammable gas hazard. This document presents the methodology for evaluating tanks in two areas of concern in the tank headspace:steady-state flammable-gas concentration resulting from continuous release, and concentration resulting from an episodic gas release.

    Lean production is a process management philosophy that examines organizational processes from a customer perspective with the goal of limiting the use of resources to those processes that create value for the end customer. Lean manufacturing emphasizes increasing efficiency, decreasing waste, and using methods to decide what matters rather than accepting preexisting practices. A rapid improvement team at Lehigh Valley Health Network, Allentown, Pennsylvania, implemented a plan, do, check, act cycle to determine problems in the central sterile processing department, test solutions, and document improved processes. By using A3 thinking, a consensus building process that graphically depicts the current state, the target state, and the gaps between the two, the team worked to improve efficiency and safety, and to decrease costs. Use of this methodology has increased teamwork, created user-friendly work areas and processes, changed management styles and expectations, increased staff empowerment and involvement, and streamlined the supply chain within the perioperative area.

    Lightning is a safety hazard for high-explosives (HE) and their detonators. In the However, the current flowing from the strike point through the rebar of the building The methodology for estimating the risk from indirect lighting effects will be presented. It has two parts: a method to determine the likelihood of a detonation given a lightning strike, and an approach for estimating the likelihood of a strike. The results of these two parts produce an overall probability of a detonation. The probability calculations are complex for five reasons: (1) lightning strikes are stochastic and relatively rare, (2) the quality of the Faraday cage varies from one facility to the next, (3) RF coupling is inherently a complex subject, (4) performance data for abnormally stressed detonators is scarce, and (5) the arc plasma physics is not well understood. Therefore, a rigorous mathematical analysis would be too complex. Instead, our methodology takes a more practical approach combining rigorous mathematical calculations where possible with empirical data when necessary. Where there is uncertainty, we compensate with conservative approximations. The goal is to determine a conservative estimate of the odds of a detonation. In Section 2, the methodology will be explained. This report will discuss topics at a high-level. The reasons for selecting an approach will be justified. For those interested in technical details, references will be provided. In Section 3, a simple hypothetical example will be given to reinforce the concepts. While the methodology will touch on all the items shown in Figure 1, the focus of this report is the indirect effect, i.e., determining the odds of a detonation from given EM fields. Professor Martin Uman from the University of Florida has been characterizing and defining extreme lightning strikes. Using Professor Uman's research, Dr. Kimball Merewether at Sandia National Laboratory in Albuquerque calculated the EM fields inside a Faraday-cage type

    It is expected that nuclear energy will be a significant component of future supplies. New facilities, operating under a strengthened international nonproliferation regime will be needed. There is good reason to believe virtual engineering applied to the facility design, as well as to the safeguards system design will reduce total project cost and improve efficiency in the design cycle. Simulation Enabled Safeguards Assessment MEthodology (SESAME) has been developed as a software package to provide this capability for nuclear reprocessing facilities. The software architecture is specifically designed for distributed computing, collaborative design efforts, and modular construction to allow step improvements in functionality. Drag and drop wireframe construction allows the user to select the desired components from a component warehouse, render the system for 3D visualization, and, linked to a set of physics libraries and/or computational codes, conduct process evaluations of the system they have designed.

    2012-01-01

    Full Text Available The size and complexity of industrial strength software systems are constantly increasing. This means that the task of managing a large software project is becoming even more challenging, especially in light of high turnover of experienced personnel. Software clustering approaches can help with the task of understanding large, complex software systems by automatically decomposing them into smaller, easier-to-manage subsystems. The main objective of this paper is to identify important research directions in the area of software clustering that require further attention in order to develop more effective and efficient clustering methodologies for software engineering. To that end, we first present the state of the art in software clustering research. We discuss the clustering methods that have received the most attention from the research community and outline their strengths and weaknesses. Our paper describes each phase of a clustering algorithm separately. We also present the most important approaches for evaluating the effectiveness of software clustering.

    The National Academy of Sciences (NAS) expects to publish the Biological Effects of Ionizing Radiation (BEIR) committee's report (BEIR VII) on risks from ionizing radiation exposures in calendar year 2005. The committee is expected to have analyzed the most recent epidemiology from the important exposed cohorts and to have factored in any changes resulting from the updated analysis of dosimetry for the Japanese atomic bomb survivors. To the extent practical, the Committee will also consider any relevant radiobiological data, including those from the Department of Energy's low dose effects research program. Based on their evaluation of relevant information, the Committee is then expected to propose a set of models for estimating risks from low-dose ionizing radiation. ORIA will review the BEIR VII report and consider revisions to the Agency's methodology for estimating cancer risks from exposure to ionizing radiation in light of this report and other relevant information. This will be the subject of the Consultation. This project supports a major risk management initiative to improve the basis on which radiation risk decisions are made. This project, funded by several Federal Agencies, reflects an attempt to characterize risks where there are substantial uncertainties. The outcome will improve our ability to assess risks well into the future and will strengthen EPAs overall capability for assessing and managing radiation risks. the BEIR VII report is funde

    2015-04-01

    Full Text Available Public sector bodies hold a significant amount of data that might be of potential interest to citizens and businesses. However the re-use potential of this data is still largely untapped because the data is not always published in a way that would allow its easy discovery, understanding and re-use. Open Government Data (OGD initiatives aim at increasing availability of machine-readable data provided under an open license and therefore these initiatives might facilitate re-use of the government data which in turn might lead to increased transparency and economic growth. However the recent studies show that still only a portion of data provided by the public sector bodies is truly open. Public sector bodies face a number of challenges when publishing OGD and they need to address the relevant risks. Therefore there is a need for best practices and methodologies for publication of OGD that would provide the responsible persons with a clear guidance on how the OGD initiatives should be implemented and how the known challenges and risks should be addressed.

  16. A Paradigm for Spreadsheet Engineering Methodologies

    CERN Document Server

    Grossman, Thomas A

    2008-01-01

    Spreadsheet engineering methodologies are diverse and sometimes contradictory. It is difficult for spreadsheet developers to identify a spreadsheet engineering methodology that is appropriate for their class of spreadsheet, with its unique combination of goals, type of problem, and available time and resources. There is a lack of well-organized, proven methodologies with known costs and benefits for well-defined spreadsheet classes. It is difficult to compare and critically evaluate methodologies. We present a paradigm for organizing and interpreting spreadsheet engineering recommendations. It systematically addresses the myriad choices made when developing a spreadsheet, and explicitly considers resource constraints and other development parameters. This paradigm provides a framework for evaluation, comparison, and selection of methodologies, and a list of essential elements for developers or codifiers of new methodologies. This paradigm identifies gaps in our knowledge that merit further research.

    This article will explore the philosophical underpinnings of the constructivist research paradigm. Despite its increasing popularity in evaluative health research studies there is limited recognition of constructivism in popular research texts. Lincoln and Guba's original approach to constructivist methodology is outlined and a detailed framework for nursing research is offered. Fundamental issues and concerns surrounding this methodology are debated and differences between method and methodology are highlighted.

  19. Methodology for assessing systems materials requirements

    Energy Technology Data Exchange (ETDEWEB)

    Culver, D.H.; Teeter, R.R.; Jamieson, W.M.

    1980-01-01

    A potential stumbling block to new system planning and design is imprecise, confusing, or contradictory data regarding materials - their availability and costs. A methodology is now available that removes this barrier by minimizing uncertainties regarding materials availability. Using this methodology, a planner can assess materials requirements more quickly, at lower cost, and with much greater confidence in the results. Developed specifically for energy systems, its potential application is much broader. This methodology and examples of its use are discussed.

  3. Formalizing the ISDF Software Development Methodology

    Directory of Open Access Journals (Sweden)

    Mihai Liviu DESPA

    2015-01-01

    Full Text Available The paper is aimed at depicting the ISDF software development methodology by emphasizing quality management and software development lifecycle. The ISDF methodology was built especially for innovative software development projects. The ISDF methodology was developed empirically by trial and error in the process of implementing multiple innovative projects. The research process began by analysing key concepts like innovation and software development and by settling the important dilemma of what makes a web application innovative. Innovation in software development is presented from the end-user, project owner and project manager’s point of view. The main components of a software development methodology are identified. Thus a software development methodology should account for people, roles, skills, teams, tools, techniques, processes, activities, standards, quality measuring tools, and team values. Current software development models are presented and briefly analysed. The need for a dedicated innovation oriented software development methodology is emphasized by highlighting shortcomings of current software development methodologies when tackling innovation. The ISDF methodology is presented in the context of developing an actual application. The ALHPA application is used as a case study for emphasizing the characteristics of the ISDF methodology. The development life cycle of the ISDF methodology includes research, planning, prototyping, design, development, testing, setup and maintenance. Artefacts generated by the ISDF methodology are presented. Quality is managed in the ISDF methodology by assessing compliance, usability, reliability, repeatability, availability and security. In order to properly asses each quality component a dedicated indicator is built. A template for interpreting each indicator is provided. Conclusions are formulated and new related research topics are submitted for debate.

    In clinical research, biostatistical methods allow the rigorous analysis of data collection and should be defined from the trial design to obtain the appropriate experimental approach. Thus, if the main purpose of phase I is to determine the dose to use during phase II, methodology should be finely adjusted to experimental treatment(s). Today, the methodology for chemotherapy and targeted therapy is well known. For radiotherapy and chemoradiotherapy phase I trials, the primary endpoint must reflect both effectiveness and potential treatment toxicities. Methodology should probably be complex to limit failures in the following phases. However, there are very few data about methodology design in the literature. The present study focuses on these particular trials and their characteristics. It should help to raise existing methodological patterns shortcomings in order to propose new and better-suited designs. Copyright © 2016 Société française de radiothérapie oncologique (SFRO).

    This technical report was prepared for a preliminary safety analysis methodology of the 330MWt SMART (System-integrated Modular Advanced ReacTor) which has been developed by Korea Atomic Energy Research Institute (KAERI) and funded by the Ministry of Science and Technology (MOST) since July 1996. This preliminary safety analysis methodology has been used to identify an envelope for the safety of the SMART conceptual design. As the SMART design evolves, further validated final safety analysis methodology will be developed. Current licensing safety analysis methodology of the Westinghouse and KSNPP PWRs operating and under development in Korea as well as the Russian licensing safety analysis methodology for the integral reactors have been reviewed and compared to develop the preliminary SMART safety analysis methodology. SMART design characteristics and safety systems have been reviewed against licensing practices of the PWRs operating or KNGR (Korean Next Generation Reactor) under construction in Korea. Detailed safety analysis methodology has been developed for the potential SMART limiting events of main steam line break, main feedwater pipe break, loss of reactor coolant flow, CEA withdrawal, primary to secondary pipe break and the small break loss of coolant accident. SMART preliminary safety analysis methodology will be further developed and validated in parallel with the safety analysis codes as the SMART design further evolves. Validated safety analysis methodology will be submitted to MOST as a Topical Report for a review of the SMART licensing safety analysis methodology. Thus, it is recommended for the nuclear regulatory authority to establish regulatory guides and criteria for the integral reactor. 22 refs., 18 figs., 16 tabs. (Author)

  12. Reliability based design optimization: Formulations and methodologies

    Science.gov (United States)

    Agarwal, Harish

    Modern products ranging from simple components to complex systems should be designed to be optimal and reliable. The challenge of modern engineering is to ensure that manufacturing costs are reduced and design cycle times are minimized while achieving requirements for performance and reliability. If the market for the product is competitive, improved quality and reliability can generate very strong competitive advantages. Simulation based design plays an important role in designing almost any kind of automotive, aerospace, and consumer products under these competitive conditions. Single discipline simulations used for analysis are being coupled together to create complex coupled simulation tools. This investigation focuses on the development of efficient and robust methodologies for reliability based design optimization in a simulation based design environment. Original contributions of this research are the development of a novel efficient and robust unilevel methodology for reliability based design optimization, the development of an innovative decoupled reliability based design optimization methodology, the application of homotopy techniques in unilevel reliability based design optimization methodology, and the development of a new framework for reliability based design optimization under epistemic uncertainty. The unilevel methodology for reliability based design optimization is shown to be mathematically equivalent to the traditional nested formulation. Numerical test problems show that the unilevel methodology can reduce computational cost by at least 50% as compared to the nested approach. The decoupled reliability based design optimization methodology is an approximate technique to obtain consistent reliable designs at lesser computational expense. Test problems show that the methodology is computationally efficient compared to the nested approach. A framework for performing reliability based design optimization under epistemic uncertainty is also developed

    We present the NNDC-BNL methodology for estimating neutron cross section covariances in thermal, resolved resonance, unresolved resonance and fast neutron regions. The three key elements of the methodology are Atlas of Neutron Resonances, nuclear reaction code EMPIRE, and the Bayesian code implementing Kalman filter concept. The covariance data processing, visualization and distribution capabilities are integral components of the NNDC methodology. We illustrate its application on examples including relatively detailed evaluation of covariances for two individual nuclei and massive production of simple covariance estimates for 307 materials. Certain peculiarities regarding evaluation of covariances for resolved resonances and the consistency between resonance parameter uncertainties and thermal cross section uncertainties are also discussed.

    2015-07-01

    Research papers present us with the summaries of scholars' work; what we readers do not see are the struggles behind the decision to choose one methodology over another. A student's mental health portfolio contained a narrative that led to an exploration of the most appropriate methodology for a projected study of clinical anecdotes told by nurses who work in mental health settings to undergraduates and new recruits about mental health nursing. This paper describes the process of struggle, beginning with the student's account, before posing a number of questions needing answers before the choice of the most appropriate methodology. We argue, after discussing the case for the use of literary analysis, discourse analysis, symbolic interactionism, hermeneutics, and narrative research, that case study research is the methodology of choice. Case study is frequently used in educational research and is sufficiently flexible to allow for an exploration of the phenomenon. © 2014 Wiley Periodicals, Inc.

The methodological defense is as follows: a commitment to realism leads scientists to pursue the truth, which in turn is apt to put them in a better position to get at the truth. In contrast, anti-realists lack the tenacity required to develop a theory to its fullest. As a consequence, they are less likely to get at the truth. My aim is to show that the methodological defense is flawed. I argue that a commitment to realism does not always benefit science, and that there is reason to believe that a research community with both realists and anti-realists in it may be better suited to advancing science. A case study of the Copernican Revolution in astronomy supports this claim.

  1. Grounded Theory as a General Research Methodology

    Directory of Open Access Journals (Sweden)

    Judith A. Holton, Ph.D.

    2008-06-01

    Full Text Available Since its inception over forty years ago, grounded theory has achieved canonical status in the research world (Locke, 2001, p.1. Qualitative researchers, in particular, have embraced grounded theory although often without sufficient scholarship in the methodology (Partington, 2000, p.93; 2002, p.136. The embrace renders many researchers unable to perceive grounded theory as a general methodology and an alternative to the dominant qualitative and quantitative research paradigms. The result is methodological confusion and an often unconscious remodelling of the original methodology (Glaser, 2003. Given the various interpretations and approaches that have been popularised under the rubric of grounded theory, this paper addresses the important distinction between grounded theory as a general methodology and its popularisation as a qualitative research method. The paper begins with a brief overview of grounded theory’s origins and its philosophical foundations then continues by addressing the basic distinction between abstract conceptualisation as employed in classic grounded theory and the conceptual description approach as adopted by many qualitative researchers. The paper continues with a brief overview of the criteria for judging the quality of classic grounded theory and concludes by detailing its methodological principles.

  2. Comparative analysis of seismic risk assessment methodology

    Park, Chang Kyoo; Kim, Tae Woon; Hwang, Mi Jung [Korea Atomic Energy Research Institute, Taejon (Korea, Republic of)

    1994-07-01

    SRA methodologies are separated into SPSA and SMM. SPSA methodology that has been widely used for seismic risk analysis has two kinds of methodologies such as Zion method and SSMRP method. SPSA methodology is suitable to interfacing with the analysis of internal event. However, the results of SPSA have uncertainties because of uncertainties in seismic hazard analysis and subjective judgement. Zion method specially developed for commercial use is less expensive and less time consuming but more uncertain than SSMRP method, since the former performs the fragility analysis less in detail than the latter. SMM is impossible to interface with the analysis of internal event but the uncertainties that are occurred during seismic hazard analysis is reduced because of the screening using RLE (review level earthquake). Therefore, if SPSA-based SMM methodology is chosen to be developed, the results of SRA will be more reliable and it requires low costs and time. In addition, the new methodology will require the development of a new evaluating code for SRA. (Author) 26 refs., 25 figs., 16 tabs.

  3. Review and evaluation of paleohydrologic methodologies

    Energy Technology Data Exchange (ETDEWEB)

    Foley, M.G.; Zimmerman, D.A.; Doesburg, J.M.; Thorne, P.D.

    1982-12-01

    A literature review was conducted to identify methodologies that could be used to interpret paleohydrologic environments. Paleohydrology is the study of past hydrologic systems or of the past behavior of an existing hydrologic system. The purpose of the review was to evaluate how well these methodologies could be applied to the siting of low-level radioactive waste facilities. The computer literature search queried five bibliographical data bases containing over five million citations of technical journals, books, conference papers, and reports. Two data-base searches (United States Geological Survey - USGS) and a manual search were also conducted. The methodologies were examined for data requirements and sensitivity limits. Paleohydrologic interpretations are uncertain because of the effects of time on hydrologic and geologic systems and because of the complexity of fluvial systems. Paleoflow determinations appear in many cases to be order-of-magnitude estimates. However, the methodologies identified in this report mitigate this uncertainty when used collectively as well as independently. That is, the data from individual methodologies can be compared or combined to corroborate hydrologic predictions. In this manner, paleohydrologic methodologies are viable tools to assist in evaluating the likely future hydrology of low-level radioactive waste sites.

  4. A design methodology for unattended monitoring systems

    Energy Technology Data Exchange (ETDEWEB)

    SMITH,JAMES D.; DELAND,SHARON M.

    2000-03-01

    The authors presented a high-level methodology for the design of unattended monitoring systems, focusing on a system to detect diversion of nuclear materials from a storage facility. The methodology is composed of seven, interrelated analyses: Facility Analysis, Vulnerability Analysis, Threat Assessment, Scenario Assessment, Design Analysis, Conceptual Design, and Performance Assessment. The design of the monitoring system is iteratively improved until it meets a set of pre-established performance criteria. The methodology presented here is based on other, well-established system analysis methodologies and hence they believe it can be adapted to other verification or compliance applications. In order to make this approach more generic, however, there needs to be more work on techniques for establishing evaluation criteria and associated performance metrics. They found that defining general-purpose evaluation criteria for verifying compliance with international agreements was a significant undertaking in itself. They finally focused on diversion of nuclear material in order to simplify the problem so that they could work out an overall approach for the design methodology. However, general guidelines for the development of evaluation criteria are critical for a general-purpose methodology. A poor choice in evaluation criteria could result in a monitoring system design that solves the wrong problem.

  5. Methodological triangulation: an approach to understanding data.

    2012-01-01

    To describe the use of methodological triangulation in a study of how people who had moved to retirement communities were adjusting. Methodological triangulation involves using more than one kind of method to study a phenomenon. It has been found to be beneficial in providing confirmation of findings, more comprehensive data, increased validity and enhanced understanding of studied phenomena. While many researchers have used this well-established technique, there are few published examples of its use. The authors used methodological triangulation in their study of people who had moved to retirement communities in Ohio, US. A blended qualitative and quantitative approach was used. The collected qualitative data complemented and clarified the quantitative findings by helping to identify common themes. Qualitative data also helped in understanding interventions for promoting 'pulling' factors and for overcoming 'pushing' factors of participants. The authors used focused research questions to reflect the research's purpose and four evaluative criteria--'truth value', 'applicability', 'consistency' and 'neutrality'--to ensure rigour. This paper provides an example of how methodological triangulation can be used in nursing research. It identifies challenges associated with methodological triangulation, recommends strategies for overcoming them, provides a rationale for using triangulation and explains how to maintain rigour. Methodological triangulation can be used to enhance the analysis and the interpretation of findings. As data are drawn from multiple sources, it broadens the researcher's insight into the different issues underlying the phenomena being studied.

    2006-10-01

    Assessing the risk of malevolent attacks against large-scale critical infrastructures requires modifications to existing methodologies that separately consider physical security and cyber security. This research has developed a risk assessment methodology that explicitly accounts for both physical and cyber security, while preserving the traditional security paradigm of detect, delay, and respond. This methodology also accounts for the condition that a facility may be able to recover from or mitigate the impact of a successful attack before serious consequences occur. The methodology uses evidence-based techniques (which are a generalization of probability theory) to evaluate the security posture of the cyber protection systems. Cyber threats are compared against cyber security posture using a category-based approach nested within a path-based analysis to determine the most vulnerable cyber attack path. The methodology summarizes the impact of a blended cyber/physical adversary attack in a conditional risk estimate where the consequence term is scaled by a ''willingness to pay'' avoidance approach.

  8. Basic methodological preconditions for high quality research

    Directory of Open Access Journals (Sweden)

    Ševkušić Slavica

    2006-01-01

    Full Text Available The paper considers basic methodological preconditions for the qualitative oriented research, in other words, the approaches which in the study of social phenomena rely on theoretical and methodological as well as epistemological premises of a new scientific paradigm. The paper draws special attention to the discussion of criteria of verifiability in qualitative research, which are significantly different from the criteria of positivist approaches. Interpretative research paradigms in social studies have a long history and numerous sources and the very concept of "interpretative shift" consists of a number of different research approaches unified under the name of qualitative methodology. The aim of the paper is not to prove that traditional and new paradigms and quantitative and qualitative research approaches based on them are incompatible in the process of discovering pedagogical reality. The intention is to demonstrate that the complexity of social phenomena requires a complex methodology meaning a complementary use of methods and techniques from both research approaches. The study of qualitative methodological approaches and their application in research, discovery and change of pedagogical reality are particularly important because they may provide new insights into pedagogical reality and a new view of old problems. .

    2012-01-01

    Full Text Available In this paper we study the possibility of modifying the conventional, advanced object-oriented methodology for software development of enterprise information systems on an enterprise services platform. The presented solution is preceded with the draft of the formal description of the business process logic and its service solutions. In the design for the introduction of business services there is used the so-called native solution that is very close to the thinking of corporate management. Adjustment of the classic, advanced object-oriented methodology is oriented on its cardinal development phases INSEPTION and ELABORATION. In these two phases important descriptions of relevant information modeling results are formed for the following CONSTRUCTION phase and TRANSITION phase. Editing, however, is methodological, and meta-documented with an example of a transparent graphical description of business services and a logical architecture of the target software.In other words, it means that this contribution provides small software companies with valuable knowledge for the creation of their own development methodologies on a platform of enterprise services. The purpose of this paper is to contribute to the formation of implementing development methodologies, which absorb current knowledge disciplines of Software and Information Engineering.

    2009-12-01

    Full Text Available According to Unconscious Thought Theory (UTT: Dijksterhuis and Nordgren, 2006, complex decisions are best made after a period of distraction assumed to elicit ``unconscious thought''. Over three studies, respectively offering a conceptual, an identical and a methodologically improved replication of Dijksterhuis et al. (2006, we reassessed UTT's predictions and dissected the decision task used to demonstrate these predictions. We failed to find any evidence for the benefits of unconscious decision-making. By contrast, we found some evidence that conscious deliberation can lead to better decisions. Further, we identified methodological weaknesses in the UTT decision task: (a attributes weighting was neglected although attributes were seen as different in importance; (b the material was not properly counterbalanced; and (c there was some confusion in the experimental instructions. We propose methodological improvements that address these concerns.

  12. Some Findings Concerning Requirements in Agile Methodologies

    Science.gov (United States)

    Rodríguez, Pilar; Yagüe, Agustín; Alarcón, Pedro P.; Garbajosa, Juan

    Agile methods have appeared as an attractive alternative to conventional methodologies. These methods try to reduce the time to market and, indirectly, the cost of the product through flexible development and deep customer involvement. The processes related to requirements have been extensively studied in literature, in most cases in the frame of conventional methods. However, conclusions of conventional methodologies could not be necessarily valid for Agile; in some issues, conventional and Agile processes are radically different. As recent surveys report, inadequate project requirements is one of the most conflictive issues in agile approaches and better understanding about this is needed. This paper describes some findings concerning requirements activities in a project developed under an agile methodology. The project intended to evolve an existing product and, therefore, some background information was available. The major difficulties encountered were related to non-functional needs and management of requirements dependencies.

    Saša T. Bakrač

    2012-04-01

    Full Text Available Successful protection of environment is mostly based on high-quality assessment of potential and present risks. Environmental risk management is a complex process which includes: identification, assessment and control of risk, namely taking measures in order to minimize the risk to an acceptable level. Environmental risk management methodology: In addition to these phases in the management of environmental risk, appropriate measures that affect the reduction of risk occurrence should be implemented: - normative and legal regulations (laws and regulations, - appropriate organizational structures in society, and - establishing quality monitoring of environment. The emphasis is placed on the application of assessment methodologies (three-model concept, as the most important aspect of successful management of environmental risk. Risk assessment methodology - European concept: The first concept of ecological risk assessment methodology is based on the so-called European model-concept. In order to better understand this ecological risk assessment methodology, two concepts - hazard and risk - are introduced. The European concept of environmental risk assessment has the following phases in its implementation: identification of hazard (danger, identification of consequences (if there is hazard, estimate of the scale of consequences, estimate of consequence probability and risk assessment (also called risk characterization. The European concept is often used to assess risk in the environment as a model for addressing the distribution of stressors along the source - path - receptor line. Risk assessment methodology - Canadian concept: The second concept of the methodology of environmental risk assessment is based on the so-called Canadian model-concept. The assessment of ecological risk includes risk arising from natural events (floods, extreme weather conditions, etc., technological processes and products, agents (chemical, biological, radiological, etc

    Vanderley de Vasconcelos

    1999-07-01

    Full Text Available A systematic methodology for microstructural description can help the task of obtaining the processing x microstructure x properties x performance relationships. There are, however, some difficulties in performing this task, which are related mainly to the following three factors: the complexity of the interactions between microstructural features; difficulties in evaluating geometric parameters of microstructural features; and difficulties in relating these geometric parameters to process variables. To solve some of these problems, it is proposed a methodology that embodies the following features: takes into account the different possible types of approaches for the microstructural description problem; includes concepts and tools of Total Quality Management; is supported on techniques of system analysis; and makes use of computer modeling and simulation and statistical design of experiments tools. The methodology was applied on evaluating some topological parameters during sintering process and its results were compared with available experimental data.

  19. Analysing Medieval Urban Space; a methodology

    Directory of Open Access Journals (Sweden)

    Marlous L. Craane MA

    2007-08-01

    Full Text Available This article has been written in reaction to recent developments in medieval history and archaeology, to study not only the buildings in a town but also the spaces that hold them together. It discusses a more objective and interdisciplinary approach for analysing urban morphology and use of space. It proposes a 'new' methodology by combining town plan analysis and space syntax. This methodology was trialled on the city of Utrecht in the Netherlands. By comparing the results of this 'new' methodology with the results of previous, more conventional, research, this article shows that space syntax can be applied successfully to medieval urban contexts. It does this by demonstrating a strong correlation between medieval economic spaces and the most integrated spaces, just as is found in the study of modern urban environments. It thus provides a strong basis for the use of this technique in future research of medieval urban environments.

    2008-01-01

    Full Text Available The test proposed by Scott Knott (1974, a procedure of means grouping, is an effective alternative to performprocedures of multiple comparisons without ambiguity. This study aimed to propose a modification related to the partitioningand means grouping in the said procedure, to obtain results without ambiguity among treatments, organized in morehomogeneous groups. In the proposed methodology, treatments that did not participate in the initial group are joined for a newanalysis, which allows for a better group distribution. In a comparative study, four experiments were simulated in a randomizedcomplete block design. The first consisted of 10 and the other 3 of 100 treatments. All experiments were performed in threereplications at a significance level of 0.05 for the means grouping test. Only in the third experiment of those of 100 treatmentsthe groups formed by Scott-Knott did not differ from the methodology proposed here. The proposed methodology is consideredeffective, aiming at the identification of elite cultivar groups for recommendation.

  1. Methodological and Analytical Dilemmas in Autoethnographic Research

    Directory of Open Access Journals (Sweden)

    Elena Maydell

    2010-01-01

    Full Text Available This article presents an argument on the application of theoretical and methodological frameworks to the study of identity from an autoethnographic perspective. In order to guide the analysis process, the author employed social constructionism as the main theoretical foundation, whereas thematic analysis and positioning theory were deployed as the methodological frameworks. Further, in the process of using ethnographic methods to study the identity of Russian immigrants to New Zealand, the author found herself also needing to use autoethnography to interrogate and understand her own journey. The insider/outsider position of the author who belongs to the same minority group became the most vital tool in her identity construction. In this regard, it is impossible to engage fully with the autoethnographic research practice without understanding the impact of others on identity construction of self, and a strong theoretical and methodological scholarship can provide a valuable foundation for this process.

    A new numerical methodology, named IMERSPEC, to solve the Navier-Stokes equations is presented in the present work and applied to solve two kinds of complex flows. It is based on Fourier pseudo-spectral (FPSM) and on immersed boundary methods (IBM). It was developed, initially, for incompressible flows. Wall boundary conditions are modeled using an IBM method. This methodology combines some advantages of high accuracy and low computational cost provided by the FPSM. Another very important characteristic is that, even for incompressible flow, there is no more pressure and velocity coupling. The performance of this new methodology is exemplified in three-dimensional numerical simulations of flows a over backward-facing step geometry and a spatial developing jet. The results are compared with experimental and with numerical results, giving very good agreement.

    Full Text Available The development of software for mobile devices takes place in a dynamic environment where constraints, technologies and user needs change very frequently requiring enhanced approaches and methodologies in software engineering essential to deal with the concept of bring your own device (BYOD. Mobile apps are developed for various purposes in different categories. This paper discusses about the challenges that affect mobile software engineering, specifically for a science educational and outreach aim as regards technologies, approaches and methodologies that could be applied to unlock the full potential of mobility. In particular, it analyzes the main challenges to development in this field, such as dealing with enhanced connectivity and networking protocols (e.g., from Bluetooth Low Energy, IEEE 802.15.4-based protocols and new Wi-Fi versions and the fragmented ecosystem of mobile platforms. Moreover, it addresses the possible application of specific development methodologies such as Agile software methods.

    2012-09-01

    Full Text Available The European Higher Education Area (EHEA has triggered many changes in the new degrees in Spanish universities, mainly in terms of methodology and assessment. However, in order to make such changes a success it is essential to have coordination within the teaching staff as well as active methodologies in use, which enhance and encourage students’ participation in all the activities carried out in the classroom. Most of all, when dealing with formative and summative evaluation, in which students become the ones responsible for their own learning process (López-Pastor, 2009; Torre, 2008. In this second issue of JOTSE we have included several teaching innovation experiences related to the above mentioned methodological and assessment changes.

    Jet Propulsion Laboratory uses multi-mission software produced by the Mission Planning and Sequencing (MPS) team to process, simulate, translate, and package the commands that are sent to a spacecraft. MPS works under the auspices of the Multi-Mission Ground Systems and Services (MGSS). This software consists of nineteen applications that are in maintenance. The MPS software is classified as either class B (mission critical) or class C (mission important). The scheduling of tasks is difficult because mission needs must be addressed prior to performing any other tasks and those needs often spring up unexpectedly. Keeping track of the tasks that everyone is working on is also difficult because each person is working on a different software component. Recently the group adopted the Scrum methodology for planning and scheduling tasks. Scrum is one of the newer methodologies typically used in agile development. In the Scrum development environment, teams pick their tasks that are to be completed within a sprint based on priority. The team specifies the sprint length usually a month or less. Scrum is typically used for new development of one application. In the Scrum methodology there is a scrum master who is a facilitator who tries to make sure that everything moves smoothly, a product owner who represents the user(s) of the software and the team. MPS is not the traditional environment for the Scrum methodology. MPS has many software applications in maintenance, team members who are working on disparate applications, many users, and is interruptible based on mission needs, issues and requirements. In order to use scrum, the methodology needed adaptation to MPS. Scrum was chosen because it is adaptable. This paper is about the development of the process for using scrum, a new development methodology, with a team that works on disparate interruptible tasks on multiple software applications.

    2010-04-01

    Full Text Available This paper presents a novel website methodology. The methodology is suitable for developing medium-sized websites and web applications as it is inspired by brainstormming and using mind maps. The proposed approach employs two well-definied roles: the interviewer and interviewee. The former could be identified with a web designer whilst the latter is more related to someone handling informatics. Practical experience has shown that a series of brainstormming sessions naturally leads to the system underlying the data-base structure.

  12. [Methodologic and epistemologic reflections on acupuncture].

    Science.gov (United States)

    Pascual, P

    1989-01-01

    Methodological difficulties met in acupuncture cannot be overcome without epistemological analysis by researchers and practitioners. This is because of the 'cognitivo-cultural' gap between Occidental and Chinese traditions. With this aim, the author considers the role of cognitive expectancies in the effect of antalgic acupuncture, and draws epistemological then methodological conclusions. After comparing the advent of the holistic movement with the crisis of rationalism in medicine, an attempt is made to formulate an evaluation of the problems in acupuncture in terms of metaphysical realism. The author challenges the holistic model compared to the orthodox bio-medical model.

    2009-01-01

    This paper describes how methodological triangulation was used in two nursing research studies. The literature identified a number of principles in reporting studies that used triangulation, including giving the rationale for using triangulation, detailing the process used to assist with triangulation and explaining how rigour was maintained. A brief review of triangulated studies revealed that few adhered fully to these principles. A 'within method' and an 'across method' study are used to illustrate how methodological triangulation was used, and the ways in which rigour was addressed are also described. In addition, the different contributions of triangulation to nursing research are highlighted.

    Theory of mind is a prominent, but highly controversial, field in psychology, psychiatry, and philosophy of mind. Simulation theory, theory-theory and other views have been presented in recent decades, none of which are monolithic. In this article, various views on theory of mind are reviewed, and methodological problems within each view are investigated. The relationship between simulation theory and Verstehen (understanding) methodology in traditional human sciences is an intriguing issue, although the latter is not a direct ancestor of the former. From that perspective, lessons for current clinical psychiatry are drawn.

    2004-07-01

    The stability window in a wellbore design is defined by the difference between fracture pressure and collapse pressure. Deep water environments typically present narrow stability windows, because rocks have low strength due to under-compaction process. Often also, horizontal wells are drilled to obtain a better development of reservoirs placed in thin layers of sandstone. In this scenario, several challenges are faced when drilling in deep water. The traditional approach for predicting instabilities is to determine collapses and fractures at borehole wall. However, the initiation of rupture does not indicate that the borehole fails to perform its function as a wellbore. Thus, a methodology in which the stability window may be enlarged is desirable. This paper presents one practical analytical methodology that consists in allowing wellbore pressures smaller than the conventional collapse pressure, i.e., based upon failure on the borehole wall. This means that a collapse region (shear failure) will be developed around the borehole wall. This collapse region is pre-defined and to estimate its size is used a failure criterion. The aforementioned methodology is implemented in a user-friendly software, which can perform analyses of stress, pore pressure, formation failure, mud weight and mud salinity design for drilling in shale formations. Simulations of a wellbore drilling in a narrow stability window environment are performed to demonstrate the improvements of using the methodology. (author)

  18. Selecting the best defect reduction methodology

    Hinckley, C.M. [Sandia National Labs., Albuquerque, NM (United States); Barkan, P. [Stanford Univ., CA (United States)

    1994-04-01

    Defect rates less than 10 parts per million, unimaginable a few years ago, have become the standard of world-class quality. To reduce defects, companies are aggressively implementing various quality methodologies, such as Statistical Quality Control Motorola`s Six Sigma, or Shingo`s poka-yok. Although each quality methodology reduces defects, selection has been based on an intuitive sense without understanding their relative effectiveness in each application. A missing link in developing superior defect reduction strategies has been a lack of a general defect model that clarifies the unique focus of each method. Toward the goal of efficient defect reduction, we have developed an event tree which addresses a broad spectrum of quality factors and two defect sources, namely, error and variation. The Quality Control Tree (QCT) predictions are more consistent with production experience than obtained by the other methodologies considered independently. The QCT demonstrates that world-class defect rates cannot be achieved through focusing on a single defect source or quality control factor, a common weakness of many methodologies. We have shown that the most efficient defect reduction strategy depend on the relative strengths and weaknesses of each organization. The QCT can help each organization identify the most promising defect reduction opportunities for achieving its goals.

    Leitão, João P; Almeida, Maria do Céu; Simões, Nuno E; Martins, André

    2013-01-01

    Pluvial or surface flooding can cause significant damage and disruption as it often affects highly urbanised areas. Therefore it is essential to accurately identify consequences and assess the risks associated with such phenomena. The aim of this study is to present the results and investigate the applicability of a qualitative flood risk assessment methodology in urban areas. This methodology benefits from recent developments in urban flood modelling, such as the dual-drainage modelling concept, namely one-dimensional automatic overland flow network delineation tools (e.g. AOFD) and 1D/1D models incorporating both surface and sewer drainage systems. To assess flood risk, the consequences can be estimated using hydraulic model results, such as water velocities and water depth results; the likelihood was estimated based on the return period of historical rainfall events. To test the methodology two rainfall events with return periods of 350 and 2 years observed in Alcântara (Lisbon, Portugal) were used and three consequence dimensions were considered: affected public transportation services, affected properties and pedestrian safety. The most affected areas in terms of flooding were easily identified; the presented methodology was shown to be easy to implement and effective to assess flooding risk in urban areas, despite the common difficulties in obtaining data.

    1999-02-01

    Probabilistic Risk Assessment (PRA) has been widely used as a tool to evaluate the safety of NPPs (Nuclear Power Plants), which are in the design stage as well as in operation. Recently, PRA becomes one of the licensing requirements for many existing and new NPPs. KALIMER is a Liquid Metal Fast Breeder Reactor (LMFBR) being developed by KAERI. Since the design concept of KALIMER is similar to that of the PRISM plant developed by GE, it would be appropriate to review the PRA methodology of PRISM as the first step of KALIMER PRA. Hence, in this report summarizes the PRA methodology of PRISM plant, and the required works for the PSA of KALIMER based on the reviewed results. The PRA technology of PRISM plant consists of following five major tasks: (1) development of initiating event list, (2) development of system event tree, (3) development of core response event tree, (4) development of containment response event tree, and (5) consequences and risk estimation. The estimated individual and societal risk measures show that the risk from a PRISM module is substantially less than the NRC goal. Each task is compared to the PRA methodology of Light Water Reactor (LWR)/Pressurized Heavy Water Reactor (PHWR). In the report, each task of PRISM PRA methodology is reviewed and compared to the corresponding part of LWR/PHWR PSA performed in Korea. The parts that are not modeled appropriately in PRISM PRA are identified, and the recommendations for KALIMER PRA are stated. (author). 14 refs., 9 tabs., 4 figs.

The methodology is based on requirements set forth in the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) and the Resource Conservation and Recovery Act (RCRA) and incorporates ``lessons learned`` from process design, remediation methodologies, and remediation projects. The methodology is applied to the treatment of 32,000 drums of mixed waste sludge at the Oak Ridge K-25 Site. Process technology options are developed and evaluated, first with regard to meeting system requirements and then with regard to CERCLA performance criteria. The following process technology options are investigated: (1) no action, (2) separation of hazardous and radioactive species, (3) dewatering, (4) drying, and (5) solidification/stabilization. The first two options were eliminated from detailed consideration because they did not meet the system requirements. A quantitative evaluation clearly showed that, based on system constraints and project objectives, either dewatering or drying the mixed waste sludge was superior to the solidification/stabilization process option. The ultimate choice between the drying and the dewatering options will be made on the basis of a technical evaluation of the relative merits of proposals submitted by potential subcontractors.

    Bedregal, Paula; Besoain, Carolina; Reinoso, Alejandro; Zubarew, Tamara

    2017-03-01

    Health care research requires different methodological approaches such as qualitative and quantitative analyzes to understand the phenomena under study. Qualitative research is usually the least considered. Central elements of the qualitative method are that the object of study is constituted by perceptions, emotions and beliefs, non-random sampling by purpose, circular process of knowledge construction, and methodological rigor throughout the research process, from quality design to the consistency of results. The objective of this work is to contribute to the methodological knowledge about qualitative research in health services, based on the implementation of the study, “The transition process from pediatric to adult services: perspectives from adolescents with chronic diseases, caregivers and health professionals”. The information gathered through the qualitative methodology facilitated the understanding of critical points, barriers and facilitators of the transition process of adolescents with chronic diseases, considering the perspective of users and the health team. This study allowed the design of a transition services model from pediatric to adult health services based on the needs of adolescents with chronic diseases, their caregivers and the health team.

    RBMN Project has been developed to design, construct and commission a national repository to dispose the low- and intermediate-level radioactive wastes from the operation of nuclear power plants and other industries that use radioactive sources and materials. Risk is a characteristic of all projects. The risks arise from uncertainties due to assumptions associated with the project and the environment in which it is executed. Risk management is the method by which these uncertainties are systematically monitored to ensure that the objectives of the project will be achieved. Considering the peculiarities of the Project, that is, comprehensive scope, multidisciplinary team, apparently polemic due to the unknowing of the subject by the stake holders, especially the community, it is being developed a specific methodology for risk management of this Project. This methodology will be critical for future generations who will be responsible for the final stages of the repository. It will provide greater guarantee to the processes already implemented and will maintain a specific list of risks and solutions for this Project, ensuring safety and security of the repository throughout its life cycle that is the planned to last at least three hundred years. This paper presents the tools and processes already defined, management actions aimed at developing a culture of proactive risk in order to minimize threats to this Project and promote actions that bring opportunities to its success. The methodology is based on solid research on the subject, considering methodologies already established and globally recognized as best practices for project management. (author)

  11. Methodology and software for georeferencing vineyards

    Directory of Open Access Journals (Sweden)

    Fialho Flávio Bello

    2016-01-01

    Full Text Available An agricultural registry is a collection of information about production area and yield of agricultural properties in a region or designated area. It allows to measure agricultural production and its spatial distribution, characterize rural structure, facilitate inspection and development of agricultural policies, optimize distribution of agricultural credit, estimate crop yield and generate research data. A key component for a quality registry is accurate measurement of areas and their geographical position, through georeferencing, to allow integration with other spatial information. The Vineyard Registry of Rio Grande do Sul is one of the most complete agricultural registries in Brazil. It has been carried out in all grape producing properties in the state since 1995, and its georeferencing began in 2005, with the objective of accurately map vineyards. Embrapa has developed a methodology to accelerate georeferencing, by simplifying the field mapping process. One of the central points of this methodology was the development of a software called MapaGPS to organize and classify measured points in the field. Recently, this software has been improved, with the incorporation of features, such as transformation between coordinate systems, conversion between files of different formats, and more control over generated charts. The georeferencing experience of the Vineyard Registry of Rio Grande do Sul may be used throughout Brazil and other countries. The software is available under a free license, and there are no restrictions to adopting the methodology. This document aims to disclose details of this methodology and how it may be used to facilitate zoning projects worldwide.

  19. Methodological remarks on studying prehistoric Greek religion

    Directory of Open Access Journals (Sweden)

    Petra Pakkanen

    1999-01-01

    Full Text Available This paper presents a methodological approach to the study of Greek religion of the period which lacks written documents, i.e. prehistory. The assumptions and interpretations of religion of that time have to be based on archaeological material. How do we define religion and cultic activity on the basis of primary archaeological material from this period, and which are the methodological tools for this difficult task? By asking questions on the nature and definition of religion and culture scholars of religion have provided us with some methodological apparatus to approach religion of the past in general, but there are models developed by archaeologists as well. Critical combination of these methodological tools leads to the best possible result. Archaeology studies the material culture of the past. History of religion studies the spiritual culture of the past. In the background the two have important theoretical and even philosophical speculations since they both deal with meanings (of things or practices and with interpretation.

  17. Experimental methodology for obtaining sound absorption coefficients

    Directory of Open Access Journals (Sweden)

    Carlos A. Macía M

    2011-07-01

    Full Text Available Objective: the authors propose a new methodology for estimating sound absorption coefficients using genetic algorithms. Methodology: sound waves are generated and conducted along a rectangular silencer. The waves are then attenuated by the absorbing material covering the silencer’s walls. The attenuated sound pressure level is used in a genetic algorithm-based search to find the parameters of the proposed attenuation expressions that include geometric factors, the wavelength and the absorption coefficient. Results: a variety of adjusted mathematical models were found that make it possible to estimate the absorption coefficients based on the characteristics of a rectangular silencer used for measuring the attenuation of the noise that passes through it. Conclusions: this methodology makes it possible to obtain the absorption coefficients of new materials in a cheap and simple manner. Although these coefficients might be slightly different from those obtained through other methodologies, they provide solutions within the engineering accuracy ranges that are used for designing noise control systems.

    Y. A. Bodina

    2014-01-01

    Full Text Available The paper considers the need for reinterpretation of the content and functions of methodological training of teacher-musicians in the higher school; the above problem being raised as the result of the massive penetration of information technologies, intensification of knowledge updates, rejection of narrow specializations, and propagation of the postmodern culture. The author focuses on modernization of methodology training of teachermusicians with the emphasis on general features of the modern musical environment affecting students’ personality. The proper methodology training of the future teacher-musicians, based on the culture-adequate knowledge and accompanied by the actual project activity forms, is capable to counteract the influence of the second-rate common musical tastes and negative world perception. In conclusion, the author highlights the need for intensification of the ontological and personal worldview orientation of methodology training and further development of professional tools. The paper is addressed to the higher school teachers and students, music school teachers, and additional education teachers.

  5. Rater methodology for stroboscopy: a systematic review.

    2015-01-01

    Laryngeal endoscopy with stroboscopy (LES) remains the clinical gold standard for assessing vocal fold function. LES is used to evaluate the efficacy of voice treatments in research studies and clinical practice. LES as a voice treatment outcome tool is only as good as the clinician interpreting the recordings. Research using LES as a treatment outcome measure should be evaluated based on rater methodology and reliability. The purpose of this literature review was to evaluate the rater-related methodology from studies that use stroboscopic findings as voice treatment outcome measures. Systematic literature review. Computerized journal databases were searched for relevant articles using terms: stroboscopy and treatment. Eligible articles were categorized and evaluated for the use of rater-related methodology, reporting of number of raters, types of raters, blinding, and rater reliability. Of the 738 articles reviewed, 80 articles met inclusion criteria. More than one-third of the studies included in the review did not report the number of raters who participated in the study. Eleven studies reported results of rater reliability analysis with only two studies reporting good inter- and intrarater reliability. The comparability and use of results from treatment studies that use LES are limited by a lack of rigor in rater methodology and variable, mostly poor, inter- and intrarater reliability. To improve our ability to evaluate and use the findings from voice treatment studies that use LES features as outcome measures, greater consistency of reporting rater methodology characteristics across studies and improved rater reliability is needed.

    Full Text Available Speech enhancement is a technique which processes the noisy speech signal. The aim of speech enhancement is to improve the perceived quality of speech and/or to improve its intelligibility. Due to its vast applications in mobile telephony, VOIP, hearing aids, Skype and speaker recognition, the challenges in speech enhancement have grown over the years. It is more challenging to suppress back ground noise that effects human communication in noisy environments like airports, road works, traffic, and cars. The objective of this survey paper is to outline the single channel speech enhancement methodologies used for enhancing the speech signal which is corrupted with additive background noise and also discuss the challenges and opportunities of single channel speech enhancement. This paper mainly focuses on transform domain techniques and supervised (NMF, HMM speech enhancement techniques. This paper gives frame work for developments in speech enhancement methodologies

    Institute of Scientific and Technical Information of China (English)

    2005-01-01

    Mission planning of organization is to select best strategy to complete its mission under the conditions of organizational states. A new methodology of generating and optimizing strategy of organizational course of actions (COA) was illuminated with a joint campaign. A process of generating and optimizing COA in military force was modeled. And enumerative and heuristic techniques were employed to search optimal strategy for the case of joint campaign. The complex between the two approaches to find best strategy was analyzed. The results from our case were given and compared with reality of joint campaign, on which deficiency of models was taken apart. The optimal COA, obtained from our new methodology under diverse campaigns conditions, is given and analyzed. Results from the simulation of the COA show that our approach to solve optimal strategy of organizational processes accords with traits of general landing campaign.

  17. Review of methodologies for Social LCA

    DEFF Research Database (Denmark)

    Jørgensen, Andreas; Hauschild, Michael Zwicky

    During the last years the interest for including social impacts in LCA has grown steadily, resulting in several preliminary Social LCA (SLCA) methodology proposals. A review of 12 methodological proposals has been made covering the most of what has been proposed as Social LCA until now focusing...... on their approaches to the goal and scope definition, inventory, and impact assessment phases of LCA. The review concludes that a main methodical difference lies in the definition of impact categories to be included in the assessment as well as in the formulation of indicators. Another challenging aspect is the data...... process. The review shows that the field of SLCA is still being framed, and that there is presently limited consensus on the approaches and that a fully developed method to support a full SLCA applying calculation procedures as known from LCA is not yet available....

    2008-01-01

    In this paper, we discuss the problem of the software engineering of a class of business spreadsheet models. A methodology for structured software development is proposed, which is based on structured analysis of data, represented as Jackson diagrams. It is shown that this analysis allows a straightforward modularisation, and that individual modules may be represented with indentation in the block-structured form of structured programs. The benefits of structured format are discussed, in terms of comprehensibility, ease of maintenance, and reduction in errors. The capability of the methodology to provide a modular overview in the model is described, and examples are given. The potential for a reverse-engineering tool, to transform existing spreadsheet models is discussed.

    Full Text Available The Italian network of "Centri Funzionali" is now reaching operational status both in hydro-meteorological risk forecasting and support to the decision making of administrations that issue natural risk warning. Each centre operates for its district of influence. In order to have a nationwide common standard the National Civil Protection Department proposed a quantitative warning methodology based on the definition of rainfall thresholds correlated to historical damages. In the first phase the thresholds have been defined using two studies that cover all Italy: the VAPI (statistics of extreme rainfall and discharges, see reference and the AVI (database of historical flood and landslide events and reported damages, see reference. This work presents one year back analysis that compares the new methodology and the one that has been usied since 2000 by the Liguria Region Meteorological Centre with regard to flood warning, pinpointing the performance differences in terms of false and missed alerts.

  2. Theoretical and methodological approaches in discourse analysis.

    Science.gov (United States)

    Stevenson, Chris

    2004-10-01

    Discourse analysis (DA) embodies two main approaches: Foucauldian DA and radical social constructionist DA. Both are underpinned by social constructionism to a lesser or greater extent. Social constructionism has contested areas in relation to power, embodiment, and materialism, although Foucauldian DA does focus on the issue of power. Embodiment and materialism may be especially relevant for researchers of nursing where the physical body is prominent. However, the contested nature of social constructionism allows a fusion of theoretical and methodological approaches tailored to a specific research interest. In this paper, Chris Stevenson suggests a frame- work for working out and declaring the DA approach to be taken in relation to a research area, as well as to aid anticipating methodological critique. Method, validity, reliability and scholarship are discussed from within a discourse analytic frame of reference.

  3. Methodology for risk analysis of projects

    Directory of Open Access Journals (Sweden)

    Roșu Maria Magdalena

    2017-01-01

    Full Text Available The risk in the organization activity as an economic and social system open, adaptive, with varying degrees of permeability to the influences from the current business environment, which is increasingly unpredictable and in which the only constant is the change, refers to the probability of not complying with the objectives set in terms of performance, execution and cost. The insufficient application of the recognized project management methodologies can be one of the main causes of projects failures in the organization with major influences on the activity efficiency and the performance recorded. Therefore, the methodology proposed in the paper, wants to be an effective tool, a formalized risk management tool, considered as a cyclical process, with several distinct phases, indispensable to the current organizational practice which should contribute to optimizing the project performance and its successful completion.

  9. Green Methodologies to Test Hydrocarbon Reservoirs

    Directory of Open Access Journals (Sweden)

    Francesca Verga

    2010-01-01

    Full Text Available Problem statement: The definition and the economic viability of the best development strategy of a hydrocarbon reservoir mainly depend on the quantity and type of fluids and on the well productivity. Well testing, consisting in producing hydrocarbon to the surface while measuring the pressure variations induced in the reservoir, has been used for decades to determine the fluid nature and well potential. In exploration and appraisal scenarios the hydrocarbons produced during a test are flared, contributing to the emissions of greenhouse gases. Approach: Due to more stringent environmental regulations and a general need for reduced operating expenses, the current industry drivers in today’s formation evaluation methodologies demand short, safe, cost-effective and environmentally friendly test procedures, especially when conventional tests are prohibitively expensive, logistically not feasible or no surface emissions are allowed. Different methods have been proposed or resuscitated in the last years, such as wireline formation tests, closed chamber tests, production/reinjection tests and injection tests, as viable alternatives to conventional well testing. Results: While various short-term tests, test procedures and interpretation methods are apparently available for conducting successful tests without hydrocarbon production at the surface, clarity is lacking for specific applications of these techniques. An attempt to clarify advantages and limitations of each methodology, particularly with respect to the main testing target is pursued in this study. Specific insight is provided on injection testing, which is one of the most promising methodology to replace traditional well testing in reservoir characterization, except for the possibility to sample the formation fluids. Conclusion/Recommendations: Not a single one method but a combination of more methodologies, in particular injection testing and wireline formation testing, is the most promising

    2015-08-01

    To create and validate a micro-costing methodology that surgeons and hospital administrators can use to evaluate the cost of implementing innovative surgical technologies. Our analysis is broken down into several elements of fixed and variable costs which are used to effectively and easily calculate the cost of surgical operations. As an example of application, we use data from 86 robot assisted gastric bypass operations made in our hospital. To validate our methodology, we discuss the cost reporting approaches used in 16 surgical publications with respect to 7 predefined criteria. Four formulas are created which allow users to import data from their health system or particular situation and derive the total cost. We have established that the robotic surgical system represents 97.53 % of our operating room's medical device costs which amounts to $4320.11. With a mean surgery time of 303 min, personnel cost per operation amounts to $1244.73, whereas reusable instruments and disposable costs are, respectively, $1539.69 and $3629.55 per case. The literature survey demonstrates that the cost of surgery is rarely reported or emphasized, and authors who do cover this concept do so with variable methodologies which make their findings difficult to interpret. Using a micro-costing methodology, it is possible to identify the cost of any new surgical procedure/technology using formulas that can be adapted to a variety of operations and healthcare systems. We hope that this paper will provide guidance for decision makers and a means for surgeons to harmonise cost reporting in the literature.

    2016-07-01

    Design of experiments (DOE) offers a great deal of benefits to any manufacturing organization, such as characterization of variables and sets the path for the optimization of the levels of these variables (settings) trough the Response surface methodology, leading to process capability improvement, efficiency increase, cost reduction. Unfortunately, the use of these methodologies is very limited due to various situations. Some of these situations involve the investment on production time, materials, personnel, equipment; most of organizations are not willing to invest in these resources or are not capable because of production demands, besides the fact that they will produce non-conformant product (scrap) during the process of experimentation. Other methodologies, in the form of algorithms, may be used to optimize a process. Known as direct search methods, these algorithms search for an optimum on an unknown function, trough the search of the best combination of the levels on the variables considered in the analysis. These methods have a very different application strategy, they search on the best combination of parameters, during the normal production run, calculating the change in the input variables and evaluating the results in small steps until an optimum is reached. These algorithms are very sensible to internal noise (variation of the input variables), among other disadvantages. In this paper it is made a comparison between the classical experimental design and one of these direct search methods, developed by Nelder and Mead (1965), known as the Nelder Mead simplex (NMS), trying to overcome the disadvantages and maximize the advantages of both approaches, trough a proposed combination of the two methodologies.

    1986-07-01

    A methodology to estimate the hazard of earthquake ground motion at a site has been developed. The methodology consists of systematic procedures to characterize earthquake sources, the seismicity parameters of those sources, and functions for the attenuation of seismic energy, incorporating multiple input interpretations by earth scientists. Uncertainties reflecting permissible alternative inperpretations are quantified by use of probability logic trees and are propagated through the hazard results. The methodology is flexible and permits, for example, interpretations of seismic sources that are consistent with earth-science practice in the need to depict complexity and to accommodate alternative hypotheses. This flexibility is achieved by means of a tectonic framework interpretation from which alternative seismic sources are derived. To estimate rates of earthquake recurrence, maximum use is made of the historical earthquake database in establishing a uniform measure of earthquake size, in identifying independent events, and in detemining the completeness of the earthquake record in time, space, and magnitude. Procedures developed as part of the methodology permit relaxation of the usual assumption of homogeneous seismicity within a source and provide unbiased estimates of recurrence parameters. The methodology incorporates the Poisson-exponential earthquake recurrence model and an extensive assessment of its applicability is provided. Finally, the methodology includes procedures to aggregate hazard results from a number of separate input interpretations to obtain a best-estimate value of hazard, together with its uncertainty, at a site.

  9. METHODOLOGICAL OPTIONS IN ECONOMIC AND MANAGEMENT RESEARCH

    Directory of Open Access Journals (Sweden)

    Dumitru ZAIȚ

    2015-06-01

    Full Text Available This article aims to search and formulate a systematic framework for choosing methodology as an essential component of research. The idea originated in quite numerous conceptual and semantic inconsistencies that we have encountered in studies provided at the expense of applied research in economics and management. I did not intend to provide examples, but those situations are not hard to find in different specialized journals, even without reference to the source. Semantic confusion, perhaps less significant in research practice in the areas mentioned, is also pretty present, and it is not at all irrelevant to talk about it, as well. The most delicate aspects of this articles’ approach have as origin some logical inconsistencies in combining various methods, techniques, procedures and research tools. The issue of methodological compatibility is important, that’s why criteria have to be established in this regard. On the basis of such incursions and critical analysis, the article proposes, with a conclusive character and as possible recommendations, a step by step procedure for the methodological choice, under a logic compatibility between methods, techniques, procedures and research instruments, on one hand, and the nature and characteristics of the field of provenience, on the other hand.

    2009-07-01

    The safety challenges posed by different mining processes were discussed in terms of geotechnical risk factors. Various mining processes can result in work hazards, a production shut-down, economic damage to the enterprise, and environmental impacts. In Estonia, risk assessment methods are utilized in different branches of industry. However, the literature on solving mining problems is limited. Various methods are applicable for solving complicated mining problems. This paper elaborated on a modified risk assessment methodology for oil shale mining in Estonia. The paper specifically discussed problems associated with oil shale mining as well as risk assessment methods such as risk analysis and risk evaluation. Topics that were introduced included risk analysis; risk identification; risk estimation; risk evaluation; risk mitigation; and risk acceptance. The modified risk assessment methodology was successfully applied to the extraction of mineral resources, stability of a mining block, and their influence on the environment. It was concluded that the methodology provides opportunity to find improved methods for new mine planning in accordance with environmental performances and the economical profit for companies. 8 refs., 2 figs.

  11. Least-cost Paths - Some Methodological Issues

    Directory of Open Access Journals (Sweden)

    Irmela Herzog

    2014-06-01

    Full Text Available This article deals with methodological issues connected with least-cost path (LCP calculations in archaeology. The number of LCP studies in archaeology has increased rapidly during the last couple of years, but not all of the approaches applied are based on an appropriate model and implementation. Many archaeologists rely on standard GIS software with default settings for calculating LCPs and are not aware of possible alternatives and the pitfalls that are described in this article. After briefly introducing the aims and applications of LCP methods in archaeology, LCP algorithms are discussed. The outcome of the LCP calculations depends not only on the algorithm but also on the cost model, which often includes several cost components. The discussion of the cost components has a focus on slope, because nearly all archaeological LCP studies take this cost component into account and because several methodological issues are connected with slope-based cost models. Other possible cost components are: the load of the walker, vegetation cover, wetlands or other soil properties, travelling and transport on water, water as barrier and as attractor, aspect, altitude, and social or cultural cost components. Eventually, advantages and disadvantages of different ways of combining cost components are presented. Based on the methodological issues I conclude that both validation checks and variations of the model are necessary to analyse the reliability of archaeological LCP results.

    Directory of Open Access Journals (Sweden)

    Richelle D. Schrock

    2013-12-01

    Full Text Available Feminist ethnography does not have a single, coherent definition and is caught between struggles over the definition and goals of feminism and the multiple practices known collectively as ethnography. Towards the end of the 1980s, debates emerged that problematized feminist ethnography as a productive methodology and these debates still haunt feminist ethnographers today. In this article, I provide a concise historiography of feminist ethnography that summarizes both its promises and its vulnerabilities. I address the three major challenges I argue feminist ethnographers currently face, which include responding productively to feminist critiques of representing "others," accounting for feminisms' commitment to social change while grappling with poststructuralist critiques of knowledge production, and confronting the historical and ongoing lack of recognition for significant contributions by feminist ethnographers. Despite these challenges, I argue that feminist ethnography is a productive methodology and I conclude by delineating its methodological imperatives. These imperatives include producing knowledge about women's lives in specific cultural contexts, recognizing the potential detriments and benefits of representation, exploring women's experiences of oppression along with the agency they exercise in their own lives, and feeling an ethical responsibility towards the communities in which the researchers work. I argue that this set of imperatives enables feminist ethnographers to successfully navigate the challenges they face.

  13. The Methodological Unboundedness of Limited Discovery Processes

    Directory of Open Access Journals (Sweden)

    John Benjamin Cassel

    2014-12-01

    Full Text Available Though designers must understand systems, designers work differently than scientists in studying systems.  Design engagements do not discover whole systems, but take calculated risks between discovery and intervention. For this reason, design practices must cope with open systems, and unpacking the tacit guidelines behind these practices is instructive to systems methodology. This paper shows that design practice yields a methodology which applies across forms of design.  Design practice teaches us to generate ideas and gather data longer, but stop when the return on design has diminished past its cost.  Fortunately, we can reason about the unknown by understanding the character of the unbounded.  We suppose that there might as well be an infinite number of factors, but we can reason about their concentration without knowing all of them.  We demonstrate this concept on stakeholder systems, showing how design discovery informs systems methodology. Using this result, we can apply the methods of parametric design when the parameters are not yet known by establishing the concentration of every kind of factor, entailing a discovery rate of diminishing returns over discovery activities, allowing the analysis of discovery-based trade-offs.  Here, we extend a framework for providing metrics to parametric design, allowing it to express the importance of discovery.

  14. On improving research methodology in clinical trials.

    Research plays a vital role within biomedicine. Scientifically appropriate research provides a basis for appropriate medical decisions; conversely, inappropriate research may lead to flawed ;best medical practices' which, when followed, contribute to avoidable morbidity and mortality. Although an all-encompassing definition of ;appropriate medical research' is beyond the scope of this article, the concept clearly entails (among other things) that research methods be continually revised and updated as better methods become available. Despite the advent of evidence-based medicine, many research methods have become ;standard' even though there are legitimate scientific reasons to question the conclusions reached by such methods. We first illustrate prominent examples of inappropriate (yet regimented) research methods that are in widespread use. Second, as a way to improve the situation, we suggest a model of research that relies on standardized statistical analyses that individual researchers must consider as a default, but are free to challenge when they can marshal sufficient scientific evidence to demonstrate that the challenge is warranted. Third, we characterize the current system as analogous to ;unnatural selection' in the biological world and argue that our proposed model of research will enable ;natural' to replace ;unnatural' selection in the choice of research methodologies. Given the pervasiveness of inappropriate research methods, we believe that there are strong scientific and ethical reasons to create such a system, that, if properly designed, will both facilitate creativity and ensure methodological rigor while protecting the public at large from the threats posed by poor medical treatment decisions resulting from flawed research methodology.

  15. A NEW METHODOLOGY ON STRATEGIC PLANNING

    Directory of Open Access Journals (Sweden)

    Hakan Bütüner

    2014-07-01

    Full Text Available A systematic method of strategic planning is anticipated to be easily understood and straightforward; based on fundamentals; and to be universally applicable for any type of business.  Accordingly, this methodology is generated for the purpose of assembling the disconnected and disorderly ideas, processes, and techniques (written on strategy and business development under the same roof, in order to develop a systematic methodology that is easily understandable and applicable. As many sources exhort managers to“think strategically” or prescribe “strategic leadership” to helicopter out of tactical day-to-day management, only a few address how to make this happen.  Where strategic analysis tools are explained, this is most frequently done conceptually rather than practically on how to utilize the tools for strategic planning.  Moreover, as fondly as it may sound, there is an exact approach or systematic thinking on this issue; our intention is to bring in a new perspective to the reader and, more significantly, to provide a different benefit by the application of this systematic methodology.Systematic strategic planning (SSP consists of a framework of phases through which each project passes, a pattern of procedures for straight-forward planning, and the fundamentals involved in any strategic planning project.

  16. SOFTWARE METRICS VALIDATION METHODOLOGIES IN SOFTWARE ENGINEERING

    Directory of Open Access Journals (Sweden)

    K.P. Srinivasan

    2014-12-01

    Full Text Available In the software measurement validations, assessing the validation of software metrics in software engineering is a very difficult task due to lack of theoretical methodology and empirical methodology [41, 44, 45]. During recent years, there have been a number of researchers addressing the issue of validating software metrics. At present, software metrics are validated theoretically using properties of measures. Further, software measurement plays an important role in understanding and controlling software development practices and products. The major requirement in software measurement is that the measures must represent accurately those attributes they purport to quantify and validation is critical to the success of software measurement. Normally, validation is a collection of analysis and testing activities across the full life cycle and complements the efforts of other quality engineering functions and validation is a critical task in any engineering project. Further, validation objective is to discover defects in a system and assess whether or not the system is useful and usable in operational situation. In the case of software engineering, validation is one of the software engineering disciplines that help build quality into software. The major objective of software validation process is to determine that the software performs its intended functions correctly and provides information about its quality and reliability. This paper discusses the validation methodology, techniques and different properties of measures that are used for software metrics validation. In most cases, theoretical and empirical validations are conducted for software metrics validations in software engineering [1-50].

  17. Does Metformin Reduce Cancer Risks? Methodologic Considerations.

    2016-01-01

    The substantial burden of cancer and diabetes and the association between the two conditions has been a motivation for researchers to look for targeted strategies that can simultaneously affect both diseases and reduce their overlapping burden. In the absence of randomized clinical trials, researchers have taken advantage of the availability and richness of administrative databases and electronic medical records to investigate the effects of drugs on cancer risk among diabetic individuals. The majority of these studies suggest that metformin could potentially reduce cancer risk. However, the validity of this purported reduction in cancer risk is limited by several methodological flaws either in the study design or in the analysis. Whether metformin use decreases cancer risk relies heavily on the availability of valid data sources with complete information on confounders, accurate assessment of drug use, appropriate study design, and robust analytical techniques. The majority of the observational studies assessing the association between metformin and cancer risk suffer from methodological shortcomings and efforts to address these issues have been incomplete. Future investigations on the association between metformin and cancer risk should clearly address the methodological issues due to confounding by indication, prevalent user bias, and time-related biases. Although the proposed strategies do not guarantee a bias-free estimate for the association between metformin and cancer, they will reduce synthesis of and reporting of erroneous results.

    2015-07-01

    The nutritional quality of food and beverage products sold in vending machines has been implicated as a contributing factor to the development of an obesogenic food environment. How comprehensive, reliable, and valid are the current assessment tools for vending machines to support or refute these claims? A systematic review was conducted to summarize, compare, and evaluate the current methodologies and available tools for vending machine assessment. A total of 24 relevant research studies published between 1981 and 2013 met inclusion criteria for this review. The methodological variables reviewed in this study include assessment tool type, study location, machine accessibility, product availability, healthfulness criteria, portion size, price, product promotion, and quality of scientific practice. There were wide variations in the depth of the assessment methodologies and product healthfulness criteria utilized among the reviewed studies. Of the reviewed studies, 39% evaluated machine accessibility, 91% evaluated product availability, 96% established healthfulness criteria, 70% evaluated portion size, 48% evaluated price, 52% evaluated product promotion, and 22% evaluated the quality of scientific practice. Of all reviewed articles, 87% reached conclusions that provided insight into the healthfulness of vended products and/or vending environment. Product healthfulness criteria and complexity for snack and beverage products was also found to be variable between the reviewed studies. These findings make it difficult to compare results between studies. A universal, valid, and reliable vending machine assessment tool that is comprehensive yet user-friendly is recommended.

    This Executive Summary provides an overview of the methodology being used by the Yucca Mountain Project (YMP) to design waste packages and ancillary components. This summary information is intended for readers with general interest, but also provides technical readers a general framework surrounding a variety of technical details provided in the main body of the report. The purpose of this report is to document and ensure appropriate design methods are used in the design of waste packages and ancillary components (the drip shields and emplacement pallets). The methodology includes identification of necessary design inputs, justification of design assumptions, and use of appropriate analysis methods, and computational tools. This design work is subject to ''Quality Assurance Requirements and Description''. The document is primarily intended for internal use and technical guidance for a variety of design activities. It is recognized that a wide audience including project management, the U.S. Department of Energy (DOE), the U.S. Nuclear Regulatory Commission, and others are interested to various levels of detail in the design methods and therefore covers a wide range of topics at varying levels of detail. Due to the preliminary nature of the design, readers can expect to encounter varied levels of detail in the body of the report. It is expected that technical information used as input to design documents will be verified and taken from the latest versions of reference sources given herein. This revision of the methodology report has evolved with changes in the waste package, drip shield, and emplacement pallet designs over many years and may be further revised as the design is finalized. Different components and analyses are at different stages of development. Some parts of the report are detailed, while other less detailed parts are likely to undergo further refinement. The design methodology is intended to provide designs that satisfy the safety

    2005-11-15

    The Kyoto Protocol and the Clean Development Mechanism (CDM) came into force on 16th February 2005 with its ratification by Russia. The increasing momentum of this process is reflected in more than 100 projects having been submitted to the CDM Executive Board (CDM-EB) for approval of the baselines and monitoring methodologies, which is the first step in developing and implementing CDM projects. A CDM project should result in a net decrease of GHG emissions below any level that would have resulted from other activities implemented in the absence of that CDM project. The 'baseline' defines the GHG emissions of activities that would have been implemented in the absence of a CDM project. The baseline methodology is the process/algorithm for establishing that baseline. The baseline, along with the baseline methodology, are thus the most critical element of any CDM project towards meeting the important criteria of CDM, which are that a CDM should result in 'real, measurable, and long term benefits related to the mitigation of climate change'. This guidebook is produced within the frame work of the United Nations Environment Programme (UNEP) facilitated 'Capacity Development for the Clean Development Mechanism (CD4CDM)' Project. This document is published as part of the projects effort to develop guidebooks that cover important issues such as project finance, sustainability impacts, legal framework and institutional framework. These materials are aimed to help stakeholders better understand the CDM and are believed to eventually contribute to maximize the effect of the CDM in achieving the ultimate goal of UNFCCC and its Kyoto Protocol. This Guidebook should be read in conjunction with the information provided in the two other guidebooks entitled, 'Clean Development Mechanism: Introduction to the CDM' and 'CDM Information and Guidebook' developed under the CD4CDM project.

  1. A Performance Tuning Methodology with Compiler Support

    Directory of Open Access Journals (Sweden)

    Oscar Hernandez

    2008-01-01

    Full Text Available We have developed an environment, based upon robust, existing, open source software, for tuning applications written using MPI, OpenMP or both. The goal of this effort, which integrates the OpenUH compiler and several popular performance tools, is to increase user productivity by providing an automated, scalable performance measurement and optimization system. In this paper we describe our environment, show how these complementary tools can work together, and illustrate the synergies possible by exploiting their individual strengths and combined interactions. We also present a methodology for performance tuning that is enabled by this environment. One of the benefits of using compiler technology in this context is that it can direct the performance measurements to capture events at different levels of granularity and help assess their importance, which we have shown to significantly reduce the measurement overheads. The compiler can also help when attempting to understand the performance results: it can supply information on how a code was translated and whether optimizations were applied. Our methodology combines two performance views of the application to find bottlenecks. The first is a high level view that focuses on OpenMP/MPI performance problems such as synchronization cost and load imbalances; the second is a low level view that focuses on hardware counter analysis with derived metrics that assess the efficiency of the code. Our experiments have shown that our approach can significantly reduce overheads for both profiling and tracing to acceptable levels and limit the number of times the application needs to be run with selected hardware counters. In this paper, we demonstrate the workings of this methodology by illustrating its use with selected NAS Parallel Benchmarks and a cloud resolving code.

    The Available Bandwidth (AB) of an end-to-end path is its remaining capacity and it is an important metric for several applications such as overlay routing and P2P networking. That is why many AB estimation tools have been published recently. Most of these tools use the Probe Rate Model, which requires sending packet trains at a rate matching the AB. Its main issue is that it congests the path under measurement. We present a different approach: a novel passive methodology to estimate the AB ...

    Physical activity may have important implications for enhancing bone density prior to the initiation of space flight, for preserving bone density during zero gravity, and for rehabilitating the skeleton upon return to Earth. Nevertheless, the beneficial effects of exercise upon the skeleton have not been proven by controlled trials and no consensus exists regarding the type, duration, and intensity of exercise necessary to make significant alterations to the skeleton. The following sections review our current understanding of exercise and osteoporosis, examine some of the methodological shortcomings of these investigations, and make research recommendations for future clinical trials.

    This paper proposes methodological guidelines for developing accident modification functions. An accident modification function is a mathematical function describing systematic variation in the effects of road safety measures. The paper describes ten guidelines. An example is given of how to use...... limitations in developing accident modification functions are the small number of good evaluation studies and the often huge variation in estimates of effect. It is therefore still not possible to develop accident modification functions for very many road safety measures. © 2015 Elsevier Ltd. All rights...

    Team building has been identified as an important method of improving the psychological climate in which teams operate, as well as overall team functioning. Within the context of sports, team building interventions have consistently been found to result in improvements in team effectiveness. In this paper we review the extant literature on team building in sport, and address a range of conceptual, methodological, and applied considerations that have the potential to advance theory, research, and applied intervention initiatives within the field. This involves expanding the scope of team building strategies that have, to date, primarily focused on developing group cohesion. Copyright © 2017 Elsevier Ltd. All rights reserved.

    1980-11-01

    Improved methodology has been developed for generating controlled test atmospheres. Vaporization of volatile liquids is accomplished in a 28 mm (O.D.) glass J-tube in conjunction with a compressed air flameless heat torch, a pressure-sensitive switch, and a positive displacement piston pump. The vaporization system has been very reliable with a variety of test materials in studies ranging from a few days to several months. The J-tube vaporization assembly minimizes the possibility of thermal decomposition of the test material and affords a better margin of safety when vaporizing potentially explosive materials.

    1996-03-01

    Feminist research is evolving, and with it new methods of doing science. In this feminist post-positivist era, grounded theory, while less inclusive and descriptive than ethnography, allows for complex analysis of complex questions. While Glaser & Strauss (the originators of this methodology) have written about grounded theory in an esoteric way, others have written extensively about this method in a much clearer and less rigid fashion. In this paper we discuss how grounded theory could be used in a creative and constantly evolving manner for feminist research.

    Directory of Open Access Journals (Sweden)

    Roberto Bueno

    2011-09-01

    Full Text Available As supposed events being accessible to a unique observer, private events posit an interesting challenge to a behavioristic psychology. Three historical variants of behaviorism dealt with the problem of private events: methodological behaviorism, radical behaviorism and interbehaviorism. The basic argument of the two last views, and that distinguishes them from the former, is that private events are comprised into the scope of an objective science of behavior. The analysis of these accounts permits us to confirm a gradual advance in behavior theory, in dealing with this issue, toward a totally monistic view.

The use of photography with its theoretical and methodological support in history is very recent, as many historians only used it for writing text illustration. Our hypothesis is that photography can be an object and source of investigation and, at the same time, an object that offers notions of its use as a specific problem in the field of visual culture.

    Sacco, Roberto; Lintas, Carla; Persico, Antonio M

    2015-10-01

    Autism is a complex neuropsychiatric disorder of developmental origin, where multiple genetic and environmental factors likely interact resulting in a clinical continuum between "affected" and "unaffected" individuals in the general population. During the last two decades, relevant progress has been made in identifying chromosomal regions and genes in linkage or association with autism, but no single gene has emerged as a major cause of disease in a large number of patients. The purpose of this paper is to discuss specific methodological issues and experimental strategies in autism genetic research, based on fourteen years of experience in patient recruitment and association studies of autism spectrum disorder in Italy.

  3. Defamiliarization as a Methodology of Literary Production

    Institute of Scientific and Technical Information of China (English)

    童燕芳

    2008-01-01

    The concept of Defamiliarization proposed by Victor Shklovsky in his Art as Technique emphasizes that a change in form to make the familiar things unfamiliar is central to the life of literature, which becomes a greatest contribution to the Russian Formalism movement. Yet the methodo-logical value embodied in dofamiliarization needs further analysis and rediscovery. To fill this gap, this paper interprets this concept as a dichotomy between imitation and novelty in the process of literary formation with the individual talents of the preducers prior to all other factors.

    2017-01-01

    In this paper, a methodology for distributed fault diagnosis is proposed. The algorithm places the sensors in a system in such a manner that the partition of a system into various subsystems becomes easier facilitating the implementation of a distributed fault diagnosis system. This algorithm also reduces or minimized the number of sensors to be used or install thus reducing overall cost. Binary integer linear programming is used for optimization in this algorithm. Real case study of Barcelona water network has been used to demonstrate and validate the proposed algorithm.

    1993-03-01

    The literature relating to feminist research both within and beyond nursing is reviewed in this paper. Feminist research is located within a post-positivist paradigm, and various definitions are considered. The distinctive methodological approach of feminist research is discussed, and interviewing and ethnography are evaluated as suitable methods for use in feminist research. Oakley's (1981) paper on interviewing women is subjected to criticism. A final section examines attempts by three sets of writers to propose evaluation criteria for feminist research. The review concludes that a number of paradoxes and dilemmas in feminist research have yet to be resolved.

    This article identifies six social-science research methodologies that will be useful for charting the sociocultural meaning of nanotechnology: web-based questionnaires, vignette experiments, analysis of web linkages, recommender systems, quantitative content analysis, and qualitative textual analysis. Data from a range of sources are used to illustrate how the methods can delineate the intellectual content and institutional structure of the emerging nanotechnology culture. Such methods will make it possible in future to test hypotheses such as that there are two competing definitions of nanotechnology - the technical-scientific and the science-fiction - that are influencing public perceptions by different routes and in different directions.

  10. Creating and evaluating a new clicker methodology

    Science.gov (United States)

    Li, Pengfei

    "Clickers", an in-class polling system, has been used by many instructors to add active learning and formative assessment to previously passive traditional lectures. While considerable research has been conducted on clicker increasing student interaction in class, less research has been reported on the effectiveness of using clicker to help students understand concepts. This thesis reported a systemic project by the OSU Physics Education group to develop and test a new clicker methodology. Clickers question sequences based on a constructivist model of learning were used to improve classroom dynamics and student learning. They also helped students and lecturers understand in real time whether a concept had been assimilated or more effort was required. Chapter 1 provided an introduction to the clicker project. Chapter 2 summarized widely-accepted teaching principles that have arisen from a long history of research and practice in psychology, cognitive science and physics education. The OSU clicker methodology described in this thesis originated partly from our years of teaching experience, but mostly was based on these teaching principles. Chapter 3 provided an overview of the history of clicker technology and different types of clickers. Also, OSU's use of clickers was summarized together with a list of common problems and corresponding solutions. These technical details may be useful for those who want to use clickers. Chapter 4 discussed examples of the type and use of question sequences based on the new clicker methodology. In several years of research, we developed a base of clicker materials for calculus-based introductory physics courses at OSU. As discussed in chapter 5, a year-long controlled quantitative study was conducted to determine whether using clickers helps students learn, how using clickers helps students learn and whether students perceive that clicker has a positive effect on their own learning process. The strategy for this test was based on

  17. Contextual factors, methodological principles and teacher cognition

    Directory of Open Access Journals (Sweden)

    2014-01-01

    Full Text Available Teachers in various contexts worldwide are sometimes unfairly criticized for not putting teaching methods developed for the well-resourced classrooms of Western countries into practice. Factors such as the teachers’ “misconceptualizations” of “imported” methods, including Communicative Language Teaching (CLT, are often blamed, though the challenges imposed by “contextual demands,” such as large class sizes, are sometimes recognised. Meanwhile, there is sometimes an assumption that in the West there is a happy congruence between policy supportive of CLT or Task-Based Language Teaching, teacher education and supervision, and curriculum design with teachers’ cognitions and their practices. Our case study of three EFL teachers at a UK adult education college is motivated by a wish to question this assumption. Findings from observational and interview data suggest the practices of two teachers were largely consistent with their methodological principles, relating to stronger and weaker forms of CLT respectively, as well as to more general educational principles, such as a concern for learners; the supportive environment seemed to help. The third teacher appeared to put “difficult” contextual factors, for example, tests, ahead of methodological principles without, however, obviously benefiting. Implications highlight the important role of teacher cognition research in challenging cultural assumptions.

    Briggs, Hugh C.; Layman, William E.

    1989-01-01

    The Control Structure Interaction Program is a technology development program for spacecraft that exhibit interactions between the control system and structural dynamics. The program objectives include development and verification of new design concepts (such as active structure) and new tools (such as a combined structure and control optimization algorithm) and their verification in ground and possibly flight test. The new CSI design methodology is centered around interdisciplinary engineers using new tools that closely integrate structures and controls. Verification is an important CSI theme and analysts will be closely integrated to the CSI Test Bed laboratory. Components, concepts, tools and algorithms will be developed and tested in the lab and in future Shuttle-based flight experiments. The design methodology is summarized in block diagrams depicting the evolution of a spacecraft design and descriptions of analytical capabilities used in the process. The multiyear JPL CSI implementation plan is described along with the essentials of several new tools. A distributed network of computation servers and workstations was designed that will provide a state-of-the-art development base for the CSI technologies.

  19. [Methodology, method, and quality of qualitative research].

    Frommer, Jörg; Rennie, David L

    2006-05-01

    Over the last ten years qualitative research approaches have been increasingly recognized and applied to the fields of psychotherapy and psychosomatic medicine in German-speaking countries, although this development has lagged behind what has occurred at the same time in English-speaking countries. In the former, especially, a misunderstanding prevails that qualitative research methods are at best preliminary to real science. This misunderstanding has roots in the philosophy of science and the sociology of knowledge. It comes from the lack of recognition that the human sciences, unlike the natural sciences, entail a double rather than single hermeneutic and that qualitative research methods are logically coherent ways of working systematically and rigorously with this double hermeneutic. Indeed, this nature of qualitative research is generally not well understood by many qualitative researchers themselves. In this article, the need for qualitative research is shown and its methodology is seen as an integration of method and hermeneutics, or methodical hermeneutics, which in turn is distinguished from alternative qualitative research methodologies. The article closes with considerations of quality criteria and publication standards.

  20. Hybrid Risk Management Methodology: A Case Study

    Directory of Open Access Journals (Sweden)

    Jacky Siu-Lun Ting

    2009-10-01

    Full Text Available Risk management is a decision-making process involving considerations of political, social, economic and engineering factors with relevant risk assessments relating to a potential hazard. In the last decade, a number of risk management tools are introduced and employed to manage and minimize the uncertainty and threats realization to the organizations. However, the focus of these methodologies are different; in which companies need to adopt various risk management principles to visualize a full picture of the organizational risk level. Regarding to this, this paper presents a new approach of risk management that integrates Hierarchical Holographic Modeling (HHM, Enterprise Risk Management (ERM and Business Recovery Planning (BCP for identifying and assessing risks as well as managing the consequences of realized residual risks. To illustrate the procedures of the proposed methodology, a logistic company ABC Limited is chosen to serve as a case study Through applying HHM and ERM to investigate and assess the risk, ABC Limited can be better evaluated the potential risks and then took the responsive actions (e.g. BCP to handle the risks and crisis in near future.

    Twitter is an online microblogging tool that disseminates more than 400 million messages per day, including vast amounts of health information. Twitter represents an important data source for the cancer prevention and control community. This paper introduces investigators in cancer research to the logistics of Twitter analysis. It explores methodological challenges in extracting and analyzing Twitter data, including characteristics and representativeness of data; data sources, access, and cost; sampling approaches; data management and cleaning; standardizing metrics; and analysis. We briefly describe the key issues and provide examples from the literature and our studies using Twitter data to understand public health issues. For investigators considering Twitter-based cancer research, we recommend assessing whether research questions can be answered appropriately using Twitter, choosing search terms carefully to optimize precision and recall, using respected vendors that can provide access to the full Twitter data stream if possible, standardizing metrics to account for growth in the Twitter population over time, considering crowdsourcing for analysis of Twitter content, and documenting and publishing all methodological decisions to further the evidence base.

    Advances in cognitive science provide a foundation for new tools that promise to advance human capabilities with significant positive impacts. As with any new technology breakthrough, associated technical and non-technical risks are involved. Sandia has mitigated both technical and non-technical risks by applying advanced surety methodologies in such areas as nuclear weapons, nuclear reactor safety, nuclear materials transport, and energy systems. In order to apply surety to the development of cognitive systems, we must understand the concepts and principles that characterize the certainty of a system's operation as well as the risk areas of cognitive sciences. This SAND report documents a preliminary spectrum of risks involved with cognitive sciences, and identifies some surety methodologies that can be applied to potentially mitigate such risks. Some potential areas for further study are recommended. In particular, a recommendation is made to develop a cognitive systems epistemology framework for more detailed study of these risk areas and applications of surety methods and techniques.

    2017-01-01

    Full Text Available Over the last forty years, case study research has undergone substantial methodological development. This evolution has resulted in a pragmatic, flexible research approach, capable of providing comprehensive in-depth understanding of a diverse range of issues across a number of disciplines. Change and progress have stemmed from parallel influences of historical transformations in approaches to research and individual researcher's preferences, perspectives, and interpretations of this design. Researchers who have contributed to the development of case study research come from diverse disciplines with different philosophical perspectives, resulting in a variety of definitions and approaches. For the researcher new to using case study, such variety can create a confusing platform for its application. In this article, we explore the evolution of case study research, discuss methodological variations, and summarize key elements with the aim of providing guidance on the available options for researchers wanting to use case study in their work.

    1980-10-01

    A methodological interface between the impact-assessment process and the decision maker is developed. Although the presented method is rather widely applicable, it is particularly helpful for those who are dealing with the complex problems surrounding the environmental, health, and economic impacts of alternative-energy technologies and policies. These problems are characterized by: (1) multiple conflicting objectives, (2) uncertainty, (3) variable outcomes over time, and (4) dynamic behavior. The issues are complicated further by the different preference structures of stakeholders, analysts, and decision makers. Minimum cost, benefit-cost, and decision analysis are three approaches that have been taken with respect to this type of problem. Decision analysis has been found to offer certain advantages over the others in that impact aggregation and uncertainty can be incorporated rather successfully. The recommended methodology has three basic stages: (1) problem formulation, (2) objective hierarchy selection, and (3) alternatives evaluation. The output of the formal analysis is assessment information that can serve as the basis of the informal processes that result in policy statements or recommendations.

  5. Methodological issues in cytokine measurement in schizophrenia

    Directory of Open Access Journals (Sweden)

    Maju Mathew Koola

    2016-01-01

    Full Text Available There is mounting evidence that inflammation is a major factor in the pathophysiology of schizophrenia. Inflammatory status is commonly ascertained by measuring peripheral cytokine concentrations. An issue concerning research on inflammation and schizophrenia relates to assay methodology. Enzyme-linked immunosorbent assay (ELISA is the most widely used and the gold standard method used to measure cytokine concentrations. ELISA has a number of limitations. Both ELISA and multiplex are limited by not being able to distinguish between bioactive and inactive molecules and the matrix and heterophilic (auto- antibody interference. Multiplex assays when combined with gene expression analysis and flow cytometry techniques such as fluorescence-activated cell sorting may be useful to detect abnormalities in specific immune pathways. Peripheral blood mononuclear cells cultures, to evaluate in vitro lipopolysaccharide-induced cytokine production, may be a better technology than measuring cytokines in the serum. The purpose of this paper is to shed light on major methodological issues that need to be addressed in order to advance the study of cytokines in schizophrenia. We make a few recommendations on how to address these issues.

  6. A Risk-Based Sensor Placement Methodology

    Energy Technology Data Exchange (ETDEWEB)

    Lee, Ronald W [ORNL; Kulesz, James J [ORNL

    2006-08-01

    A sensor placement methodology is proposed to solve the problem of optimal location of sensors or detectors to protect population against the exposure to and effects of known and/or postulated chemical, biological, and/or radiological threats. Historical meteorological data are used to characterize weather conditions as wind speed and direction pairs with the percentage of occurrence of the pairs over the historical period. The meteorological data drive atmospheric transport and dispersion modeling of the threats, the results of which are used to calculate population at risk against standard exposure levels. Sensor locations are determined via a dynamic programming algorithm where threats captured or detected by sensors placed in prior stages are removed from consideration in subsequent stages. Moreover, the proposed methodology provides a quantification of the marginal utility of each additional sensor or detector. Thus, the criterion for halting the iterative process can be the number of detectors available, a threshold marginal utility value, or the cumulative detection of a minimum factor of the total risk value represented by all threats.

    2014-09-01

    Performance advantages of the new digital technologies are widely acknowledged, but it has proven difficult for utilities to derive business cases for justifying investment in these new capabilities. Lack of a business case is often cited by utilities as a barrier to pursuing wide-scale application of digital technologies to nuclear plant work activities. The decision to move forward with funding usually hinges on demonstrating actual cost reductions that can be credited to budgets and thereby truly reduce O&M or capital costs. Technology enhancements, while enhancing work methods and making work more efficient, often fail to eliminate workload such that it changes overall staffing and material cost requirements. It is critical to demonstrate cost reductions or impacts on non-cost performance objectives in order for the business case to justify investment by nuclear operators. This Business Case Methodology approaches building a business case for a particular technology or suite of technologies by detailing how they impact an operator in one or more of the three following areas: Labor Costs, Non-Labor Costs, and Key Performance Indicators (KPIs). Key to those impacts will be identifying where the savings are “harvestable,” meaning they result in an actual reduction in headcount and/or cost. The report consists of a Digital Technology Business Case Methodology Guide and an accompanying spreadsheet workbook that will enable the user to develop a business case.

    Istrate, C.; Herghiligiu, I. V.

    2016-08-01

    The current business situation is extremely complicated. Business must adapt to the changes in order (a) to survive on the increasingly dynamic markets, (b) to meet customers’ new request for complex, customized and innovative products. In modern manufacturing organizations it can be seen a substantial improvement regarding the management of knowledge. This occurs due to the fact that organizations realized that knowledge and an efficient management of knowledge generates the highest value. Even it could be said that the manufacturing organizations were and are the biggest beneficiary of KM science. Knowledge management performance (KMP) evaluation in manufacturing organizations can be considered as extremely important because without measuring it, they are unable to properly assess (a) what goals, targets and activities must have continuity, (b) what must be improved and (c) what must be completed. Therefore a proper KM will generate multiple competitive advantages for organizations. This paper presents a developed methodological framework regarding the KMP importance regarding manufacturing organizations. This methodological framework was developed using as research methods: bibliographical research and a panel of specialists. The purpose of this paper is to improve the evaluation process of KMP and to provide a viable tool for manufacturing organizations managers.

  12. Regression-Based Artificial Neural Network Methodology in Response Surface Methodology

    何桢; 肖粤翔

    2004-01-01

    Response surface methodology (RSM) is an important tool for process parameter optimization, robust design and other quality improvement efforts. When the relationship between influential input variables and output response is very complex, it' s hard to find the real response surface using RSM. In recent years artificial neural network(ANN) has been used in RSM. But the classical ANN does not work well under the constraints of real applications. An algorithm of regression-based ANN(R-ANN) is proposed in this paper, which is a supplement to the classical ANN methodology. It makes network closer to the response surface, so that training time is reduced and robustness is strengthened. The procedure of improving ANN by regressions is described and the comparisons among R-ANN, RSM and classical ANN are computed graphically in three examples. Our research shows that the R-ANN methodology is a good supplement to the RSM and classical ANN methodology,which can yield lower standard error of prediction under conditions that the scope of experiment is rigidly restricted.

    Urban metabolism analysis has become an important tool for the study of urban ecosystems. The problems of large metabolic throughput, low metabolic efficiency, and disordered metabolic processes are a major cause of unhealthy urban systems. In this paper, I summarize the international research on urban metabolism, and describe the progress that has been made in terms of research methodologies. I also review the methods used in accounting for and evaluating material and energy flows in urban metabolic processes, simulation of these flows using a network model, and practical applications of these methods. Based on this review of the literature, I propose directions for future research, and particularly the need to study the urban carbon metabolism because of the modern context of global climate change. Moreover, I recommend more research on the optimal regulation of urban metabolic systems.

    2012-12-01

    Full Text Available Recently, Lean Production (Lean has become a prevailing management concept in Sweden. However, previous research seems to show that the Lean concept and the impact of Lean vary considerably between organizations. This paper illustrates some key methodological issues that need to be considered when researching loosely defined management concepts such as Lean. The paper is based on a review of the literature and five comparative Swedish cases studies. Our study indicates that Lean has changed over time and that operationalization and interpretations of the concept vary considerably. This study concludes that future Lean studies should include a thorough assessment of the Lean interventions, study settings, and in particular non-Lean factors mediating the outcomes of Lean-inspired change programs.

    Deregulation of the electricity industry aims for creating a competitive market to trade electricity, which generates a host of new technical challenges among market participants and power system researchers. One of the major challenges is to establish a cost for system services on a nondiscriminatory basis. In this paper, the evaluation of transmission cost is proposed based on sensitivity factor method like AC Power Transfer Distribution Factor (ACPTDF) method for bilateral and multilateral transactions. The transacted power is estimated by ACPTDF method for each transaction. The advantages of the proposed methodology are demonstrated on a sample 6 bus, IEEE 30 bus and Indian Utility 69 bus systems. The solution provides a better pricing approach that can impact a more reasonable economic indicator for transmission cost.

    Full Text Available In this article, the author reports on a method crafted to interrogate the data of a Gadamerian hermeneutic phenomenological study that explored hope seen through the eyes of a small number of Australian youth. She advocates for transparency throughout data analysis, by commencing with an explication of Gadamerian hermeneutic phenomenology, followed by a description of the manner by which the data were interrogated. It is a basic premise of this work that all too often authors have adopted thematic analysis uncritically, and have used this method of analysis without considering its fit to the philosophical or methodological orientation of the study, and this practice has remained, by and large, unchallenged. While not advocating against thematic analysis per se, the author disputes that this analytical method is appropriate for studies that are grounded by the philosophical underpinnings of Gadamerian hermeneutic phenomenology, and therefore offers a unique method of data analysis.

    Theory of Inventive Problem Solving (TRIZ) is a powerful tool widely used in engineering community. It is based on identification of a physical contradiction in a problem, and based on the corresponding pair of contradicting parameters selecting a few of suitable inventive principles, narrowing down the choice and leading to a much faster solution of a problem. It is remarkable that TRIZ methodology can also be applied to scientific disciplines. Many of TRIZ inventive principles can be post factum identified in various in scientific inventions and discoveries. However, additional inventive principles, more suitable for scientific disciplines, should be introduced and added to standard TRIZ, and some of the standard inventive principles need to be reformulated to be better applicable to science - we call this extension Accelerating Science TRIZ. In this short note we describe and illustrate the AS-TRIZ inventive principles via scientific examples, identifying AS-TRIZ inventive principles in discoveries and inv...

  10. Methodological questions in studying consonant acquisition

    Science.gov (United States)

    Edwards, Jan; Beckman, Mary E.

    2009-01-01

    Consonant mastery is one of the most widely used metrics of typical phonological acquisition and of phonological disorder. Two fundamental methodological questions concerning research on consonant acquisition are (1) how to elicit a representative sample of productions and (2) how to analyse this sample once it has been collected. This paper address these two questions by reviewing relevant aspects of experience in evaluating word-initial consonant accuracy from transcriptions of isolated-word productions elicited from 2- and 3-year-olds learning four different first languages representing a telling range of consonant systems (English, Cantonese, Greek, Japanese). It is suggested that both researchers and clinicians should consider a number of different item-related factors, such as phonotactic probability and word length, when constructing word lists to elicit consonant productions from young children. This study also proposes that transcription should be supplemented by acoustic analysis and the perceptual judgements of naïve listeners. PMID:19031192

    Thermal performance of the thermal protection system was approximately as predicted. The only extensive anomalies were filler bar scorching and over-predictions in the high Delta p gap heating regions of the orbiter. A technique to predict filler bar scorching has been developed that can aid in defining a solution. Improvement in high Delta p gap heating methodology is still under study. Minor anomalies were also examined for improvements in modeling techniques and prediction capabilities. These include improved definition of low Delta p gap heating, an analytical model for inner mode line convection heat transfer, better modeling of structure, and inclusion of sneak heating. The limited number of problems related to penetration items that presented themselves during orbital flight tests were resolved expeditiously, and designs were changed and proved successful within the time frame of that program.

    @@ Precision Measurement Physics deals with the frontier problems in science, and plays a multi-disciplinary and fundamental role in strongly advancing the sciences. It is well known that an improvement of measuring precision in physics by an order of magnitude often implies a new or unknown effect to be explored, consequently even a new physical law to be established. There is no doubt that the development of modern physics is so closely related to precision measurements. During the past few decades, the methodologies and physics of precision measurements have achieved tremendous breakthroughs, and therefore have extended our understanding of the physics world.In addition, some technologies developed in this process have been applied in our daily life. Also, we can expect Precision Measurement Physics to make more significant progress toward verifying the basic laws of physics, and to find more practical applications in the future.

  20. Strategy and methodology of dynamical analogue prediction

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    In order to effectively improve numerical prediction level by using current models and data, the strategy and methodology of dynamical analogue prediction (DAP) is deeply studied in the present paper. A new idea to predict the prediction errors of dynamical model on the basis of historical analogue information is put forward so as to transform the dynamical prediction problem into the estimation problem of prediction errors. In terms of such an idea, a new prediction method of final analogue correction of errors (FACE) is developed. Furthermore, the FACE is applied to extra-seasonal prediction experiments on an operational atmosphere-ocean coupled general circulation model. Prediction results of summer mean circulation and total precipitation show that the FACE can to some extent reduce prediction errors, recover prediction variances, and improve prediction skills. Besides, sensitive experiments also show that predictions based on the FACE are evidently influenced by the number of analogues, analogue-selected variables and analogy metric.

To begin with, general and special methodology are defined; then, the main uses of qualitative methods are described and the focus of the paper on the study of meaning and of abstract concepts in the context of embodied cognition is justified. It is emphasized that three uses of qualitative methods converge in the study of embodied cognition: (1) classification, given that it is centered on concepts, (2) discovery, because theories are not yet well articulated and inductive effort is required, and (3) the study of meaning. The final recommendation is to profit from the opportunity of constructing special techniques that the transformation of cognitive psychology is favoring; in this context, varieties of emotion become a privileged object of study.

    Full Text Available The article addresses the role of national images in international relations and develops a methodological framework for its study. It concludes that national image study should comprise private frames associated with perceived images of other nations, and public frames referring to projected media images of other nations by drawing on framing theory. It suggests that in-depth interview with intermediate elites can be employed to explore private frames, and the inductive or the deductive approaches to public frames. There is recognition that inquiry is conducted in the shadow of a dynamic world politics and within a historical context, and public diplomacy can be used to build national reputation. To examine the associations between public and private frames of a given country will prepare the ways for the identification of alternative frames and framing devices that may result in variation in public opinion, contributing to national image building in the state under study, and promote understanding and relationships between countries.

    Fractal analysis has become a popular method in all branches of scientific investigations including biology and medicine. Although there is a growing interest in the application of fractal analysis in biological sciences, questions about the methodology of fractal analysis have partly restricted its wider and comprehensible application. It is a notable fact that fractal analysis is derived from fractal geometry, but there are some unresolved issues that need to be addressed. In this respect, we discuss several related underlying principles for fractal analysis and establish the meaningful relationship between fractal analysis and fractal geometry. Since some concepts in fractal analysis are determined descriptively and/or qualitatively, this paper provides their exact mathematical definitions or explanations. Another aim of this study is to show that nowadays fractal analysis is an independent mathematical and experimental method based on Mandelbrot's fractal geometry, Euclidean traditiontal geometry and Richardson's coastline method.

    Randomized controlled trials (RCTs) are the gold standard method for developing evidence-based medicine in inflammatory bowel disease (IBD). Methodological problems in RCTs in IBD concern different aspects such as the definition of the study population due to the extreme variability of patients with IBD, the indices of disease activity, a clearly defined outcome, the environmental risk factors (i.e smoking behaviour) that may influence the randomization, the heterogeneous placebo rate of remission and the different statistical methods used to analyze the results. It is important that trials are designed efficiently, done well and complement clinical practice with a careful subject selection, standardization of disease activity indices, and precise outcome measurement in order to continue the improvement of the IBD research process.

    Full Text Available Introduction: The main role model of medical ethics is to explain and clarify the proper conducts appropriate to those involved in the profession of medicine. In other words, one can say that through the methodologies of medical ethics, new conclusions and inferences are to be reached and achieved to describe and explain the end aims of this approach towards the moral and ethical aspects of medical sciences. So the different roles and responsibilities in this field can be classified as follows: 1. To present ways and methods whereby and ethical and moral framework can be attained and achieved. 2. To present and show ways by which this framework can be implemented and applicable. 3. To face challenges and remove obstacles in the absence of this framework. Methods:This investigation on medical ethics has been dealt with on a library, descriptive and analytic basis, and the subject has been described, analyzed and clarified on the basis of transcendental philosophy presented by Mulla Sadra. Results: Different methodologies concerning medical ethics have been forwarded, classified and grouped as empirical, religious, philosophy, legal and allegorical methods in view of ethical theories based on Islamic teachings and customs and traditions practiced in medical sciences. Having all the above-mentioned points in mind, a researcher in this field can succeed in achieving their goals if the Islamic medical ethics is taken into consideration. By following the philosophical example belonging to Mulla Sadra, an Islamic- Iranian methodology in this field can be based and founded whereby the relationships between different sciences can be firstly explained and clarified, in an appropriate manner and secondly there will be no contrasts and contradictions in regard to the principles of religion in a way that the position of the Islamic laws and jurisprudence will be rightly presented, respected and put into practice. Conclusion:It can be worth while, here, to

The purpose of this review is to compare these approaches in order to highlight methodological differences and general shortcomings. SLCA has several...... stage in the product life cycle. Another very important difference among the proposals is their position towards the use of generic data. Several of the proposals argue that social impacts are connected to the conduct of the company leading to the conclusion that each individual company in the product...... and formulation of indicators. The indicators address a wide variety of issues; some approaches focus on impacts created in the very close proximity of the processes included in the product system, whereas others focus on the more remote societal consequences. Only very little focus has been given to the use...

  8. Interpretive research methodology: broadening the dialogue.

    Lowenberg, J S

    1993-12-01

    This article expands the dialogue on interpretive research methodology, locating this set of approaches within a broad historical and interdisciplinary context. Several of the most commonly held misconceptions in nursing, particularly those related to the meanings and derivations ascribed to "grounded theory," "symbolic interactionism," and "ethnography," are examined. The interpretive research approaches not only have gained broader acceptance across disciplines, but also have shifted in more radical and often less structured directions during the past decade. Several pivotal areas of these ongoing shifts are analyzed for their relevance to nursing research: the influence of critical and feminist theory and postmodernism, the ambiguity inherent in both every-day life and the research enterprise, the importance of locating the researcher, power and status inequities, the problematic aspects of language, meaning, and representation, and the emphasis on reflexivity and context as constitutive of meaning.

    Full Text Available It is often assumed that an eclectic approach to teaching a second language is desirable, as no single method can be regarded as universally ideal. Such a mixed methodologies approach was adopted in an ESL course at the University of Newcastle in Australia, deliberately incorporating the use of CALL techniques to enhance the success of a variety of other methods. Surprisingly, students who reported to have enjoyed the CALL classes and testified to their practical usefulness fared worse in the examinations than students in the previous five years, when CALL techniques were not used The. writer speculates on the possible reasons for this unexpected finding, and cites a further example of the lack of success of a mixed methodologies approach. Dit word dikwe/s aangeneem dat 'n eklektiese benadering tot tweedetaalonde"ig wenslik is, aangesien dit aanvaar word dat geen onde"igmetode as universeel ideaal beskou kan word nie. Met die aanname in gedagte, is 'n gemengde metodologiese benadering gebruik vir die aanbieding van 'n Engels tweedetaalkursus aan die Universiteit van Newcastle in Australie. Die kursus het, bo en behalwe die gewone tweedetaalonde"igmetodes, ook gebruik gemaak van CALL-tegnieke (dw.s. rekenaar-ondersteunde leertegnieke met die bedoeling om die taalverwerwingsproses op die wyse te bevorder. Teen die verwagting in het studente wat aangedui het dat die rekenaarklasse genotvol en waardevol was, swakker in die eindeksamen gevaar as die gemiddelde student wat geen CALL-onderrig in dieseifde kursus oor die vorige vyf jaar ontvang het nie. Die skrywer spekuleer oor die moontlike redes vir hierdie onverwagte swak vertoning en ve~s na nog 'n voorbeeld van onsuksesvol/e resultate na die gebruik van 'n gemengde-metode-benadering.

  10. Unification of the methodology of competitiveness evaluation

    Full Text Available The purpose of the study is the comparison of the modern methods of competitiveness evaluation and testing the results in practice at a production plant in order to unify the methodology. Analysis of the publications shows that the existing diversity in methods of the competitiveness evaluation complicates the choice of a method and interpretation of the results, which confirms the need to classify and unify the methods available today. The authors suggest that the standardized method of competitiveness evaluation should combine matrix and graphical methods. In our study, we have shown that SWOT-analysis should be carried out in two stages: firstly, it is necessary to determine the strengths and weaknesses of the company, taking into account the following factors: marketing, production, economic and financial situation, technology, the administration and personnel; secondly, it is essential to assess the opportunities and threats with the allowance for the political, legal, and economic situation, the impact of market as well as social, cultural and natural environmental factors. The proposed methodology of competitiveness evaluation has been tested at the industrial enterprise "Olvita ltd", which is dynamically developing and successfully operates on the food market of Ukraine; it specializes in processing, logistics and distribution of fresh and frozen vegetables, fruits and berries, as well as ready-to cook meat products. The results have shown that the competitiveness evaluation remains a pressing issue that requires simple and fairly demonstrative methods, one of which is a method that combines both graphical and matrix approaches. The advantage of the proposed method is its sufficiently high visualizations and record of personal approaches in evaluating the scores for strengths and weaknesses as well as opportunities and threats. In the future, the authors are planning to examine and systemize the indicators used in the competitiveness

  11. Diesel injector fouling bench test methodology

    Compared to conventional compression ignition (CI) engine operation with the fuel being delivered at approximately 149 C (300 F), adiabatic engine operation potentially may deliver the fuel at temperatures as high as 260 C (500 F). Hypergolic CI engine combustion systems now in theoretical design stages will deliver fuel at temperatures approaching 427 to 538 C (800 to 1000 F). The ability of a fuel to resist formation of deposits on internal injector system surfaces is a form of thermal oxidative stability for which test methodology will be required. The injector Fouling Bench Test (IFBT) methodology evaluated in this report will assist in defining fuel contribution to injector fouling and control of fuel thermal stability in procurement specifications. The major observations from this project are discussed. Forty-hour cyclic IFB tests employing both Bosch APE 113 and Detroit Diesel (DD) N70 injectors are viable procedures for evaluating fuel effects on injector fouling. Cyclic operation appears to be superior to steady-state operation for both type injectors. Eighty-hour cyclic tests are more discriminating than 40-hour cyclic tests using the Bosch APE 113 injectors. JFTOT tests of fuels provide directional information on thermal stability-related deposits and filter plugging but show limited good correlation with IFBT DD N70 ratings, and none with IFBT Bosch APE 113 injector ratings. Deposition on injector pintles was more realistically rated by optical microscopy and Scanning Electron Microscopy (SEM) than conventional visual and bench rating methods. High-sulfur fuel readily caused sticking of Detroit Diesel injectors. Injector sticking is an important mode of injector fouling.

  12. Methodological findings in studies on adoptive families

    Directory of Open Access Journals (Sweden)

    Kalus, Alicja

    2014-09-01

    Full Text Available The issue of adoptive families is the object of interest for many researchers, especially outside Polish borders. A critical analysis of previous studies on adoption shows that the scientific value of many of the existing studies raises doubts. The reasons of this are more or less significant methodological weaknesses, which significantly reduce their scientific value. Researchers often focus on the study of individuals in the adoptive family, e.g. mothers only, adopted children only or selected types of relationships within the family e.g. the mother – child relation. There is a little amount of studies on family systems. It seems worthy to note that numerous studies are conducted in the cause-effect model of explaining phenomena in the adoptive family. Such approach to the study of reality, which is the family, is regarded as too big simplification. Therefore, there is an important reason to undertake the scientific discourse on the research methodology on the adoptive family. Discussed in the paper issues include: theoretical models, arrangement of studies, especially the selection of the test group and the research methods used in the study on adoptive families. Conducting scientific research is essential for the adoption practice. Among psychologists-practitioners exists a disturbing belief that working with adoptive families can be based on the experience gained in psychological practice. This fact can be explained by the existing lack of willingness of adoptive families to cooperate in the field of scientific research. Lack of this cooperation significantly limits the access to the study population of adoptive families.

    Full Text Available Current methodologies of information systems penetration testing focuses mainly on a high level and technical description of the testing process. Unfortunately, there is no methodology focused primarily on the management of these tests. It often results in a situation when the tests are badly planned, managed and the vulnerabilities found are unsystematically remediated. The goal of this article is to present new methodology called PETA which is focused mainly on the management of penetration tests. Development of this methodology was based on the comparative analysis of current methodologies. New methodology incorporates current best practices of IT governance and project management represented by COBIT and PRINCE2 principles. Presented methodology has been quantitatively evaluated.

    Full Text Available There has been an increasing need for geospatial information that is delivered through internet technologies. This broad category of systems is referred to as Web Geographic Information Systems (Web GIS. These systems exhibit characteristics common to both stand-alone and web-based systems making it necessary to apply a hybrid methodology during their development. This paper proposes a methodology for developing Web GIS that is herein referred to as the Y-Model Web GIS Development Methodology (YWDM which has been adapted from existing software development methodologies and applied to the context of Web GIS development. The paper outlines in details the phases of the methodology. Its viability as a methodology has been tested through its use in the implementation of the Emuhaya Web GIS portal. The methodology presented here is not intended to be a rigid guide for web GIS development but instead it provides a useful framework for guiding the process.

    Paszkiewicz, Zbigniew; Picard, Willy

    While Enterprise Architecture Modeling (EAM) methodologies become more and more popular, an EAM methodology tailored to the needs of virtual organizations (VO) is still to be developed. Among the most popular EAM methodologies, TOGAF has been chosen as the basis for a new EAM methodology taking into account characteristics of VOs presented in this paper. In this new methodology, referred as Virtual Organization Breeding Methodology (VOBM), concepts developed within the ECOLEAD project, e.g. the concept of Virtual Breeding Environment (VBE) or the VO creation schema, serve as fundamental elements for development of VOBM. VOBM is a generic methodology that should be adapted to a given VBE. VOBM defines the structure of VBE and VO architectures in a service-oriented environment, as well as an architecture development method for virtual organizations (ADM4VO). Finally, a preliminary set of tools and methods for VOBM is given in this paper.

  19. Methodological approaches in the research of organizational culture

    Directory of Open Access Journals (Sweden)

    Janićijević Nebojša

    2011-01-01

    Full Text Available In the thirty-years-long research of organizational culture, two mutually opposed methodological approaches have emerged: objectivistic quantitative and subjectivistic-qualitative. These two approaches are based on opposite ontological and epistemological assumptions: they include different types of research, and use opposite, quantitative vs. qualitative, methods of research. Each of the methodological approaches has its advantages and disadvantages. For this reason a hybrid approach emerges as a legitimate choice in organizational culture research methodology. It combines elements of both subjectivistic and objectivistic methodological approaches, according to the goals, content, and context of the research and preferences of the researcher himself/herself. Since it is possible to combine the two principal methodological approaches in various ways, there are several possible hybrid methodologies in organizational culture research. After the review of objectivistic quantitative and subjectivistic-qualitative methodological approaches, one of possible hybrid approaches in the research of organizational culture is presented in this paper.

    Full Text Available This paper introduces the methodology for modeling business processes. Creation of the methodology is described in terms of the Design Science Method. Firstly, the gap in contemporary Business Process Modeling approaches is identified and general modeling principles which can fill the gap are discussed. The way which these principles have been implemented in the main features of created methodology is described. Most critical identified points of the business process modeling are process states, process hierarchy and the granularity of process description. The methodology has been evaluated by use in the real project. Using the examples from this project the main methodology features are explained together with the significant problems which have been met during the project. Concluding from these problems together with the results of the methodology evaluation the needed future development of the methodology is outlined.
