    Reviewers of research reports frequently criticize the choice of statistical methods. While some of these criticisms are well-founded, frequently the use of various parametric methods such as analysis of variance, regression, correlation are faulted because: (a) the sample size is too small, (b) the data may not be normally distributed, or (c) The data are from Likert scales, which are ordinal, so parametric statistics cannot be used. In this paper, I dissect these arguments, and show that many studies, dating back to the 1930s consistently show that parametric statistics are robust with respect to violations of these assumptions. Hence, challenges like those above are unfounded, and parametric methods can be utilized without concern for "getting the wrong answer". PMID:20146096

    Experiments using NASA's Advanced Communications Technology Satellite were conducted to provide an estimate of the compressed video quality required for preservation of clinically relevant features for the detection of trauma. Bandwidth rates of 128, 256 and 384 kbps were used. A five point Likert scale (1 equals no useful information and 5 equals good diagnostic quality) was used for a subjective preference questionnaire to evaluate the quality of the compressed ultrasound imagery at the three compression rates for several anatomical regions of interest. At 384 kbps the Likert scores (mean plus or minus SD) were abdomen (4.45 plus or minus 0.71), carotid artery (4.70 plus or minus 0.36), kidney (5.0 plus or minus 0.0), liver (4.67 plus or minus 0.58) and thyroid (4.03 plus or minus 0.74). Due to the volatile nature of the H.320 compressed digital video stream, no statistically significant results can be derived through this methodology. As the MPEG standard has at its roots many of the same intraframe and motion vector compression algorithms as the H.261 (such as that used in the previous ACTS/AMT experiments), we are using the MPEG compressed video sequences to best gauge what minimum bandwidths are necessary for preservation of clinically relevant features for the detection of trauma. We have been using an MPEG codec board to collect losslessly compressed video clips from high quality S- VHS tapes and through direct digitization of S-video. Due to the large number of videoclips and questions to be presented to the radiologists and for ease of application, we have developed a web browser interface for this video visual perception study. Due to the large numbers of observations required to reach statistical significance in most ROC studies, Kappa statistical analysis is used to analyze the degree of agreement between observers and between viewing assessment. If the degree of agreement amongst readers is high, then there is a possibility that the ratings (i.e., average Likert score at each bandwidth) do in fact reflect the dimension they are purported to reflect (video quality versus bandwidth). It is then possible to make intelligent choice of bandwidth for streaming compressed video and compressed videoclips.

    2014-12-01

    The present study was designed to investigate personality item-writing practices and their effect on the psychometric properties of personality items and scales. Personality items were developed based on ideal-point and dominance models, analyzed using the generalized graded unfolding model, and empirically classified as having an ideal-point or dominance form. Results suggested that writing dominance items were slightly easier (more successful) than writing ideal-point items, but this varied slightly by personality dimensions. Of 3 ideal-point item writing tactics, the "neutral" tactic was least successful; success writing "double-barreled" and "average" ideal-point items was comparable to that of dominance items. Three personality scales were then constructed using successful ideal-point and dominance items. Scales constructed using ideal-point items had substantially inferior psychometric properties, including lower score reliability, lower correlations with important criteria, and mixed test information results. However, lower predictive validity of ideal-point scale scores may be due to lower reliability of the scores. Practical and methodological implications were also discussed.

    This study examined the relative precision (RP) of two methods of scoring the 10-item Physical Functioning Scale (PF-10) from a large sample of patients (n = 3445) of the Medical Outcomes Study. Based on a Likert scaling model, the PF-10 summated scoring method was compared with a Rasch Item Response Theory (IRT) scaling model in which raw scores were transformed into a latent trait variable of physical functioning. Potential differences between scoring methods were hypothesized to be attributed to: (1) the logarithmic nature of the Rasch transformation; (2) the unevenness of the PF-10 item distributions; and (3) reduction of within-group variance. RP ratios favored the Rasch model in discriminating between patients who differed in disease severity. The Rasch and Likert scoring models performed similarly for tests involving sensitivity to change over a two-year follow-up period. In all comparisons, differences between methods were most apparent in clinical groups whose scores most approximated the extremes of the score distribution. Further research is necessary to test for differences between scoring models in discrimination and sensitivity to change among clinical groups whose scores are sufficiently spread across the continuum of physical functioning, in particular patients with either very high or low physical functioning. The Rasch model of scoring may have important implications for the clinical interpretation of individual scores at all ranges of the scale. PMID:9179104

  16. Five critical questions of scale for the coastal zone

    Swaney, D. P.; Humborg, C.; Emeis, K.; Kannen, A.; Silvert, W.; Tett, P.; Pastres, R.; Solidoro, C.; Yamamuro, M.; Hénocque, Y.; Nicholls, R.

    2012-01-01

    Social and ecological systems around the world are becoming increasingly globalized. From the standpoint of understanding coastal ecosystem behavior, system boundaries are not sufficient to define causes of change. A flutter in the stock market in Tokyo or Hong Kong can affect salmon producers in Norway or farmers in Togo. The globalization of opportunistic species and the disempowerment of people trying to manage their own affairs on a local scale seem to coincide with the globalization of trade. Human-accelerated environmental change, including climate change, can exacerbate this sense of disenfranchisement. The structure and functioning of coastal ecosystems have been developed over thousands of years subject to environmental forces and constraints imposed mainly on local scales. However, phenomena that transcend these conventional scales have emerged with the explosion of human population, and especially with the rise of modern global culture. Here, we examine five broad questions of scale in the coastal zone: How big are coastal ecosystems and why should we care? Temporal scales of change in coastal waters and watersheds: Can we detect shifting baselines due to economic development and other drivers? Are footprints more important than boundaries? What makes a decision big? The tyranny of small decisions in coastal regions. Scales of complexity in coastal waters: the simple, the complicated or the complex? These questions do not have straightforward answers. There is no single "scale" for coastal ecosystems; their multiscale nature complicates our understanding and management of them. Coastal ecosystems depend on their watersheds as well as spatially-diffuse "footprints" associated with modern trade and material flows. Change occurs both rapidly and slowly on human time scales, and observing and responding to changes in coastal environments is a fundamental challenge. Apparently small human decisions collectively have potentially enormous consequences for coastal environmental quality, and our success in managing the effects of these decisions will determine the quality of life in the coastal zone in the 21st century and beyond. Vigilant monitoring, creative synthesis of information, and continued research will be necessary to properly understand and govern our coastal environments into the future.

  20. A mixed-binomial model for Likert-type personality measures

    PubMed Central

    Allik, Jüri

    2014-01-01

    Personality measurement is based on the idea that values on an unobservable latent variable determine the distribution of answers on a manifest response scale. Typically, it is assumed in the Item Response Theory (IRT) that latent variables are related to the observed responses through continuous normal or logistic functions, determining the probability with which one of the ordered response alternatives on a Likert-scale item is chosen. Based on an analysis of 1731 self- and other-rated responses on the 240 NEO PI-3 questionnaire items, it was proposed that a viable alternative is a finite number of latent events which are related to manifest responses through a binomial function which has only one parameter—the probability with which a given statement is approved. For the majority of items, the best fit was obtained with a mixed-binomial distribution, which assumes two different subpopulations who endorse items with two different probabilities. It was shown that the fit of the binomial IRT model can be improved by assuming that about 10% of random noise is contained in the answers and by taking into account response biases toward one of the response categories. It was concluded that the binomial response model for the measurement of personality traits may be a workable alternative to the more habitual normal and logistic IRT models. PMID:24847291

  2. The Right Scale for the Question Asked: A Challenge for Great Lakes Hydrology and Restoration Forecasts

    NASA Astrophysics Data System (ADS)

    Hunt, R.; Walker, J. F.; Christiansen, D.

    2012-12-01

    Water is a primary metric for viewing Great Lakes health and restoration. Our ability to characterize and forecast hydrologic conditions continues to improve, but challenges remain. One notable issue is the scale of the Great Lakes system. Because of its size, constructing a tractable model that encompasses the entire watershed requires extensive simplification. Questions that require higher spatial and temporal resolution, however, often cannot be well-simulated using the coarse resolution of Great Lakes watershed-scale tools. In work conducted for the Great Lake Restoration Initiative, a regional Precipitation-Runoff Modeling System (PRMS) model has been constructed for the entire Lake Michigan watershed. The model was parameterized using Hydrologic Response Units of about 207 square kilometers, and 148 stream gages ranging in HUC 8-12 scales. This representation of the system is useful for annual and perhaps seasonal/monthly characterizations of water fluxes to Lake Michigan. Likewise, this scale of forecast can be useful for certain predictions, such as lake stage forecasts where Lake Michigan is the basinwide receptor - a receptor that is a natural integrator of large space and time. Many questions need a more refined characterization of the dynamics and processes operating within the system. For these, such a coarse representation of space and time is not appropriate. Many Great Lakes issues, such as localized Areas of Concern (AOCs) and Harmful Algal Blooms (HABs), are not well represented by basinwide averages. For example, annual flows are not useful for assessing the resilience of a sand-capping restoration activity to future climate variability. In this work, a spatially detailed PRMS model has been refined from the regional PRMS model to construct more representative forecasts for these types of questions. The sub-basin model needs to answer the smaller scale question, but must also be consistent with the conceptualization and parameterization of the regional framework. These issues underscore the need to use all the tools in the toolbox, and not direct inordinate effort to unrealistic goals, such as a single simulator that represents all spatial and temporal scales. That is, there can be no expectation of "the" model for a Great Lake, only a family of models tuned for constructing forecasts for specific questions.

    Purpose To compare the diagnostic performance of the magnetic resonance (MR) imaging-based Prostate Imaging Reporting and Data System (PI-RADS) and a Likert scale in the detection of prostate cancer in a cohort of patients undergoing initial prostate biopsy. Materials and Methods This institutional review board-approved two-center prospective study included 118 patients with normal digital rectal examination (DRE) results but elevated prostate-specific antigen (PSA) levels (4-20 ng/mL) who were referred for initial prostate biopsies and had one suspicious (Likert scale score, ?3) focus at prebiopsy 1.5-T multiparametric MR imaging performed with T2-weighted, diffusion-weighted [DW], and dynamic contrast material-enhanced imaging. Targeted core biopsies and random systematic core biopsies were performed. The elementary unit for analysis was the core. Relationships were assessed by using the Mann-Whitney U test. Yates corrected and Pearson ?(2) tests were used to evaluate categoric variables. A training set was randomly drawn to construct the receiver operating characteristic curves for the summed PI-RADS scores and for the Likert scale scores. The thresholds to recommend biopsy were obtained from the Youden J statistics and were tested in the remaining validation set in terms of predictive characteristics. Interobserver variability was analyzed by using weighed ? statistics in a random set of 50 patients. Results Higher T2-weighted, DW, and dynamic contrast-enhanced imaging PI-RADS scores were observed in areas that yielded cancer-positive cores. The percentage of positive cores increased with the sum of scores aggregated in five classes as follows: For summed PI-RADS scores of 3-5, the percentage of positive cores was 2.3%; for scores of 6-8, it was 5.8%; for scores of 9 or 10, it was 24.7%; for scores of 11 or 12, it was 51.8%; and for scores of 13-15, it was 72.1% (P for trend, <.0001). For the threshold of summed PI-RADS scores of 9 or greater, sensitivity was 86.6%, specificity was 82.4%, the positive predictive value was 52.4%, the negative predictive value was 96.5%, and accuracy was 83.2%. The respective data for Likert scale scores of 3 or greater were 93.8%, 73.6%, 44.3%, 98.1%, and 73.3%. Good interobserver agreement was observed for the Likert scale (? = 0.80) and the summed PI-RADS (? = 0.73) scoring systems. Conclusion PI-RADS provided the site-specific stratified risk of cancer-positive cores in biopsy-naive men with normal DRE results and elevated PSA levels. There was no significant difference between summed PI-RADS scores of 9 or greater and Likert scale scores of 3 or greater in the detection of cancer in the peripheral zone. (©) RSNA, 2015.

    Comparing self-assessed indicators of subjective outcomes such as health, work disability, political efficacy, job satisfaction, etc. across countries or socio-economic groups is often hampered by the fact that different groups use different response scales. This paper develops an integrated framework in which objective measurements are used to validate vignette-based corrections. The framework is applied to objective and subjective self-assessments of drinking behavior by students in Ireland. Model comparisons using the Akaike information criterion favor a specification with response consistency and vignette corrected response scales. Put differently, vignette based corrections appear quite effective in bringing objective and subjective measures closer together. PMID:23526119

  7. The Rosenberg Self-Esteem Scale: a bifactor answer to a two-factor question?

    2014-01-01

    Despite its long-standing and widespread use, disagreement remains regarding the structure of the Rosenberg Self-Esteem Scale (RSES). In particular, concern remains regarding the degree to which the scale assesses self-esteem as a unidimensional or multidimensional (positive and negative self-esteem) construct. Using a sample of 3,862 high school students in the United Kingdom, 4 models were tested: (a) a unidimensional model, (b) a correlated 2-factor model in which the 2 latent variables are represented by positive and negative self-esteem, (c) a hierarchical model, and (d) a bifactor model. The totality of results including item loadings, goodness-of-fit indexes, reliability estimates, and correlations with self-efficacy measures all supported the bifactor model, suggesting that the 2 hypothesized factors are better understood as "grouping" factors rather than as representative of latent constructs. Accordingly, this study supports the unidimensionality of the RSES and the scoring of all 10 items to produce a global self-esteem score. PMID:24940657

  11. A Mathematical Approach in Evaluating Biotechnology Attitude Scale: Rough Set Data Analysis

    ERIC Educational Resources Information Center

    Narli, Serkan; Sinan, Olcay

    2011-01-01

    Individuals' thoughts and attitudes towards biotechnology have been investigated in many countries. A Likert-type scale is the most commonly used scale to measure attitude. However, the weak side of a likert-type scale is that different responses may produce the same score. The Rough set method has been regarded to address this shortcoming. A…

    Looking at cell to cell differences within a tumor bed, contributed by either DNA mutations, epigenetic or post-translational modifications (PTM) or miRNA mediated control switches or even a combination of all these, the question rise how to best design a personalized drug trial?

    If this important question is answered we would be able to develop a highly tailored therapeutic approach for cancers. Actually, inflammatory type of the anti-tumor immune response such as IFN-g can also induce initial tumor inhibition but eventual tumor escape and progression.

    Cancer.gov

    Gemcitabine is a widely used drug for pancreatic cancer therapy, but due to poor prognosis this drug is now in question. Cells resistance to gemcitabine activates EMT in the background, but the drug itself is a potential replication blocker and activates apoptosis, then why gemcitabine induced apoptosis activates a kind of fleeting mechanism (EMT) to get protection from apoptotic threat?

    Cancer.gov

    This is a great question. Gene-based targeting has contributed significantly to decrease mortality. Despite the unexplored black box of molecular mechanisms, these drugs were highly effective as first line of therapy. However over time, a percentage of patients were either non-responders or developed resistance. Our deep knowledge of molecular mechanisms has helped redesign some of the drugs, or established diagnostic tests to stratify patients that would benefit from such drugs.

    Cancer.gov

    Sequencing of natural human tumors is teaching us invaluable lessons. It is becoming clear that the new dogmas created in the post genome era are being questioned. The previously suspected genetic heterogeneity of tumors is now proven on the sequence level. The extreme genetic heterogeneity of individual tumors and the existence of multiple tumors (not metastases) pose fundamental doubt on the prevailing dogma of targeted drug(s) and personalized treatments.

  17. question_1303305591 — Provocative Questions

    Cancer.gov

    This is an outstanding and intellectually-stimulating question which introduces a new way to translate more effectively metastasis research to the clinic. It is certainly worth exploring and badly needed. because, if positive, drugs could be immediately useful to help defined populations of patients. Per points, we agree that these are limited metastasis groups; however, results could at minimum justify moving forward to full adjuvant trials. Worthy cause given the "bottleneck" we experience nowadays since drugs are mostly not tested in metastasis prevention.

  18. Fermi Questions

    NSDL National Science Digital Library

    Math Forum

    2001-01-01

    Fermi questions emphasize estimation, numerical reasoning, communicating in mathematics, and questioning skills. Students often believe that word problems have one exact answer and that the answer is derived in a unique manner. Fermi questions encourage multiple approaches, emphasize process rather than the answer, and promote non-traditional problem solving strategies. The a href= /workshops/sum96/interdisc/sheila3.html Fermi Questions Library/a features classic Fermi questions with annotated solutions, a list of Fermi questions for use with students, Fermi questions with a Louisiana twist, and Fermi activities for the K-12 classroom.

    Stable isotopes appear as ideal tracer commonly applied in preferential flow analyses. At the same time, central assumptions about signature mixing and propagation are founded on effective parameters merging advective and diffusive flow domains. However, in structured soils conditions are often far from well-mixed and some established assumptions may need to be reconsidered. We conducted a multi-tracer sprinkler experiment at a forested hillslope in the Attert Basin in Luxembourg with prevailing geogenic and biogenic preferential flow structures. At plot scale of 1x1 m2 we sprinkled two plots with 50 mm and one plot with 30 mm Brilliant Blue and Bromide enriched water for 1 hour. The experiments were accompanied by a high resolution 3D time-lapse GPR (Ground-Penetrating Radar) survey scanning 3x3 m2 before, directly after sprinkling and before excavation one day after sprinkling. Soil moisture was monitored with a TDR tube probe. Soil profiles were excavated and recorded for dye flow paths and for one medium resolution Bromide profile. In addition one core for pore water stable isotope analysis was taken before the sprinkling as reference and at each plot after sprinkling. We present the results with focus on the found evidence of preferential flow and the signals of the different tracers - especially the stable isotopes. While all other methods clearly show that only minor proportions of the soil took part in the infiltration process and that the sprinkler water has largely advectively propagated to the saprolite layer at about 80-100 cm depth, the stable isotopes signals from the cores indicate more intense interaction between the soil matrix and macropores, especially in the top 50 cm. This leads to the question of how the isotope signal could mix well, when most of the pore-water did not directly interact with the infiltration-water. Further questions arise to the use of tracers in general, due to the known limitations of excavation itself and rather coarse sampling with sizes 1-2 orders of magnitude larger than most preferential flow structures - thus blurring the signal. Moreover, considerable uncertainty arises where intense staining may be due to slow water movement or large quantities of infiltrated water. Here time-lapse GPR provides promising insights identifying patterns and states. Moreover, we will discuss whether the use of multiple tracers instead of just one leads to additional information and better understanding of subsurface processes.

    Cardoso, Clareci Silva; Bandeira, Marina; Ribeiro, Antonio Luiz Pinho; Oliveira, Graziella Lage; Caiaffa, Waleska Teixeira

    2011-01-01

    Satisfaction is an important measure of quality care, of adherence to the treatment and adequate use of health services. The objective here is to build two scales which evaluates team' and patients' satisfaction with cardiovascular disease treatment provided through a distance telecardiology project. The procedure followed international standards for development of measure instruments, including operational definition of satisfaction contents and its area for evaluation; item definition; pre-test and pilot study. The literature review, focal groups and discussion with specialists had delimited the domains to be included in the scales and the elaboration of its items. The CARDIOSATIS-Team included 15 items and the CARDIOSATIS-Patient included 11. Satisfaction was measured through a five-point Likert scale. The scales' items comprised satisfaction with physical structure, human resources, capacity of resolution, attention and care offered by the service and the satisfaction with the received/given care. The scales also included open questions. CARDIOSATIS scales have showed to be an easy and accessible instrument very well accepted by medical team and patients. Preliminary results presented good characteristics of validity and reliability. PMID:21503491

  11. Cosmic questions: an introduction.

    PubMed

    Primack, J R; Abrams, N E

    2001-12-01

    This introductory talk at the Cosmic Questions conference sponsored by the AAAS summarizes some earlier pictures of the universe and some pictures based on modern physics and cosmology. The uroboros (snake swallowing its tail) is an example of a traditional picture. The Biblical flat-earth picture was very different from the Greek spherical earth-centered picture, which was the standard view until the end of the Middle Ages. Many people incorrectly assume that the Newtonian picture of stars scattered through otherwise empty space is still the prevailing view. Seeing Earth from space shows the power of a new picture. The Hubble Space Telescope can see all the bright galaxies, all the way to the cosmic Dark Ages. We are at the center of cosmic spheres of time: looking outward is looking backward in time. All the matter and energy in the universe can be represented as a cosmic density pyramid. The laws of physics only allow the material objects in the universe to occupy a wedge-shaped region on a diagram of mass versus size. All sizes--from the smallest size scale, the Planck scale, to the entire visible universe--can be represented on the Cosmic Uroboros. There are interesting connections across this diagram, and the human scale lies in the middle. PMID:11797741

  12. Is there a group effect? It depends on how you ask the question: intraclass correlations for California Psychotherapy Alliance Scale-Group items.

    PubMed

    2015-01-01

    California Psychotherapy Alliance Scale-Group (CALPAS-G) data were collected from 1,138 group sessions attended by 248 group members in 16 counseling groups. Hierarchical linear modeling (HLM) was used to derive between-groups, between-member, and between-session variance components and intraclass correlation coefficients (ICCs) for the 12 CALPAS-G items. Using Ledermann and Kenny's (2012) descriptions of variable types, we examined differences in between-groups variance for the 6 CALPAS-G items classified as "Individual" items and the 6 CALPAS-G items classified as "Group" items. A Related-Samples Wilcoxon's Signed Ranked Test showed that the ICCs for the Group items were significantly larger than the ICCs for the Individual items. The results show the importance of how items are worded. If researchers want to accurately examine the between-groups component of the group therapy relationship they should develop measures that ask clients to describe their perceptions of the group, not the members own experience of the group.

    Mahomed, N.; Gandhi, Rajiv; Daltroy, Lawrence; Katz, J. N.

    2011-01-01

    Introduction. The objective of this study was to develop a short self-report questionnaire for evaluating patient satisfaction with the outcome of hip and knee replacement surgery. Methods. This scale consists of four items focusing on satisfaction with the extent of pain relief, improvement in ability to perform home or yard work, ability to perform recreational activities, and overall satisfaction with joint replacement. This instrument does not measure satisfaction with process of care. The responses are scored on a Likert scale, with the total score ranging from 25 to 100 per question. The instrument was tested on 1700 patients undergoing primary total hip and total knee replacement surgery, evaluated preoperatively, at 12 weeks, and one year postoperatively. Psychometric testing included internal consistency, measured with Cronbach's alpha, and convergent validity, measured by correlation with changes in measures of health status between the preoperative, 12-week, and one-year evaluations. Results. The internal consistency (reliability) of the scale, measured by the Cronbach's alpha, ranged from 0.86 to 0.92. The scale demonstrated substantial ceiling effects at 1 year. The scale scores correlated modestly with the absolute SF-36 PCS and WOMAC scores (? = 0.56–0.63 and also with the WOMAC change scores (? = 0.38–0.46) at both 12-week and 1-year followups. Conclusions. This instrument is valid and reliable for measuring patient satisfaction following primary hip and knee arthroplasty and could be further evaluated for use with other musculoskeletal interventions.

    Musical scales involve notes that, sounded simultaneously (chords), sound good together. The result is the left brain meeting the right brain ? a Pythagorean interval of overlapping notes. This synergy would suggest less difference between the working of the right brain and the left brain than common wisdom would dictate. The pleasing sound of harmony comes when two notes share a common harmonic, meaning that their frequencies are in simple integer ratios, such as 3/2 (G/C) or 5/4 (E/C).

    Schaeffer, Nora Cate; Dykema, Jennifer

    2011-01-01

    We begin with a look back at the field to identify themes of recent research that we expect to continue to occupy researchers in the future. As part of this overview, we characterize the themes and topics examined in research about measurement and survey questions published in Public Opinion Quarterly in the past decade. We then characterize the field more broadly by highlighting topics that we expect to continue or to grow in importance, including the relationship between survey questions and the total survey error perspective, cognitive versus interactional approaches, interviewing practices, mode and technology, visual aspects of question design, and culture. Considering avenues for future research, we advocate for a decision-oriented framework for thinking about survey questions and their characteristics. The approach we propose distinguishes among various aspects of question characteristics, including question topic, question type and response dimension, conceptualization and operationalization of the target object, question structure, question form, response categories, question implementation, and question wording. Thinking about question characteristics more systematically would allow study designs to take into account relationships among these characteristics and identify gaps in current knowledge.

    2011-01-01

    The purpose of this study was to test the factor validity and reliability of the Center for Epidemiologic Studies Depression Scale (CES-D) within a sample of adolescents with mild to moderate Intellectual Disability (ID). A total sample of 189 adolescents (121 boys and 68 girls), aged between 12 and 18 years old, with mild to moderate ID were involved in two studies. In study 1, the content, phrasing and answering format of the CES-D were adapted for adolescents with ID. This instrument was renamed CES-D for ID (CES-D-ID) and two different versions based on two alternative answer scales (Likert and Likert-graphical) were developed and their psychometric properties were verified in study 2. The results provided support for the factor validity, reliability and invariance across gender and age of a 14-item version of the CES-D-ID based on a Likert-graphical answer scale. PMID:21530161

    Question answering (QA) is a relatively new area of research. We took the approach of designing a question answering system that is based on question classification and document tagging. Question classification extracts useful information from the question about how to answer the question. Document tagging extracts useful information from the documents, which are used to find the answer to the

  9. What is a Question?

    NASA Technical Reports Server (NTRS)

    Knuth, Kevin H.; Clancy, Daniel (Technical Monitor)

    2002-01-01

    A given question can be defined in terms of the set of statements or assertions that answer it. Application of the logic of inference to this set of assertions allows one to derive the logic of inquiry among questions. There are interesting symmetries between the logics of inference and inquiry; where probability describes the degree to which a premise implies an assertion, there exists an analogous quantity that describes the bearing or relevance that a question has on an outstanding issue. These have been extended to suggest that the logic of inquiry results in functional relationships analogous to, although more general than, those found in information theory. Employing lattice theory, I examine in greater detail the structure of the space of assertions and questions demonstrating that the symmetries between the logical relations in each of the spaces derive directly from the lattice structure. Furthermore, I show that while symmetries between the spaces exist, the two lattices are not isomorphic. The lattice of assertions is described by a Boolean lattice 2(sup N) whereas the lattice of real questions is shown to be a sublattice of the free distributive lattice FD(N) = 2(sup 2(sup N)). Thus there does not exist a one-to-one mapping of assertions to questions, there is no reflection symmetry between the two spaces, and questions in general do not possess unique complements. Last, with these lattice structures in mind, I discuss the relationship between probability, relevance and entropy.

    Health care is just now feeling the effects of many years of neglect of serious attention to quality outcomes. We have many tools available now to change our thinking and to provide techniques to attain excellence in quality, such as Six Sigma and principals from Toyota. However, these techniques will only get us to a minimal level of quality. We need to change our questions, think the impossible, and break out of our old modes of thinking about quality. Zero defects are possible. We only have to take that quantum leap and think in new ways. We are posed on the edge of a quantum leap into new ways of thinking about quality. We will hear much more about nurse-sensitive indicators in the near future. Nurse leaders should change their questions now to attend to new models that will get us closer to the ultimate "impossible thinking" goal of zero defects in nurse-sensitive indicators of quality.

Biology shows us that you can't plan ahead very far. New things come along that you don't even have a category for, and therefore you don't even see them. Things are going to happen that you literally have no notion are even possible. The key to succeeding in this environment? Don't plan ahead. Stay curious. Make small bets.

    The natural language database query system incorporated in the Knobs Interactive Planning System comprises a dictionary driven parser, APE-II, and script interpreter whch yield a conceptual dependency as a representation of the meaning of user input. A conceptualisation pattern matching production system then determines and executes a procedure for extracting the desired information from the database. In contrast to syntax driven q-a systems, e.g. those based on atn parsers, APE-II is driven bottom-up by expectations associated with word meanings. The goals of this approach include utilising similar representations for questions with similar meanings but widely varying surface structures, developing a powerful mechanism for the disambiguation of words with multiple meanings and the determination of pronoun referents, answering questions which require inferences to be understood, and interpreting ellipses and ungrammatical statements. The Knobs demonstration system is an experimental, expert system for air force mission planning applications. 16 refs.

    This is a great question. Gene-based targeting has contributed significantly to decrease mortality. Despite the unexplored black box of molecular mechanisms, these drugs were highly effective as first line of therapy. However over time, a percentage of patients were either non-responders or developed resistance. Our deep knowledge of molecular mechanisms has helped redesign some of the drugs, or established diagnostic tests to stratify patients that would benefit from such drugs.

    The importance of this question depends on what sort of research will be considered important to fund. If we prioritize research on the tumor cell and forget about the host response, we might miss the answer. This has in part been happening in many studies over many years that attempted to find the most effective chemotherapy by testing its effects on the growth of a xenograft in an immunocompromized mouse.

    In this column questions concerning wisdom are addressed, such as, what is wisdom? Can wisdom be taught in the academy? Several perspectives on wisdom from philosophy, education, business, and psychology are presented. Wisdom with creativity-creativity with wisdom is then explored through discussion of Parse's humanbecoming teaching-learning model and Laird Hamilton's life lessons learned from surfing, which he termed wisdom of the wave. The column concludes with consideration of the wise person. PMID:19342709

  6. Fundamental Questions of Practical Cosmology

    Baryshev, Yurij; Teerikorpi, Pekka

    The book guides the reader (astronomer, physicist, university student) through central questions of Practical Cosmology, a term used by the late Allan Sandage to denote the modern scientific enterprise to find out the cosmological model best describing the universe of galaxies, its geometry, size, age, and material contents. The authors draw from their personal experience in astrophysics and cosmology to explain key concepts of cosmology, both observational and theoretical, and to highlight several items which give cosmology its special character: - idiosyncratic features of the "cosmic laboratory" - Malmquist bias in determination of cosmic distances - theory of gravitation as a cornerstone of cosmological models - crucial tests checking the reality of space expansion - methods of analyzing the structures of the universe as mapped by galaxies - usefulness of fractal as a model to describe the large-scale structure - new cosmological physics inherent in the Friedmann world model

  7. Neutrino Oscillations:. Hierarchy Question

    The only experimentally observed phenomenon that lies outside the standard model of the electroweak interaction is neutrino oscillations. A way to try to unify the extensive neutrino oscillation data is to add a phenomenological mass term to the Lagrangian that is not diagonal in the flavor basis. The goal is then to understand the world's data in terms of the parameters of the mixing matrix and the differences between the squares of the masses of the neutrinos. An outstanding question is what is the correct ordering of the masses, the hierarchy question. We point out a broken symmetry relevant to this question, the symmetry of the simultaneous interchange of hierarchy and the sign of ?13. We first present the results of an analysis of data that well determine the phenomenological parameters but are not sensitive to the hierarchy. We find ?13 = 0.152±0.014, ? 23 = 0.25{ - 0.05}{ + 0.03} ? and ?32 = 2.45±0.14×10-3 eV2, results consistent with others. We then include data that are sensitive to the hierarchy and the sign of ?13. We find, unlike others, four isolated minimum in the ?2-space as predicted by the symmetry. Now that Daya Bay and RENO have determined ?13 to be surprisingly large, the Super-K atmospheric data produce meaningful symmetry breaking such that the inverse hierarchy is preferred at the 97.2 % level.

    The first section of this memoir queries my formative years. Indirectly I address the question, did my childhood and early years make a difference in my choice of career? Why and how did I begin my journey to becoming a scientist? Did I choose the field of solar astronomy or did circumstances dictate it for me? In the second section, I travel through my work environments and experiences, talking about interactions and aspects of being a scientist that do not appear in our research papers. What parts of my research were happenstances and what parts did I plan? What does it feel like to be on scientific quests? Using examples in my journey, I also turn to questions that have intrigued me throughout my sojourn as a solar astronomer. How do scientific discoveries come about? What factors lead to little discoveries? And what factors lead to major exciting discoveries? Are there timely questions we do not think to ask? How can small, seemingly scattered pieces of knowledge suddenly coalesce into a deeper understanding - what is called the "Aha!" experience - the times when our mental light switches on, and with child-like wonder we behold a "big picture"?

  9. The competency question.

    Ruthemeyer, M

    2000-01-01

    JCAHO mandates "processes that are designed to ensure that the competency of all staff members is assessed, maintained, demonstrated, and improved on an ongoing basis." However, it is difficult to collect aggregate data regarding staff competency patterns and trends. How many facilities have the time or energy to collect aggregate data, let alone statistically analyze it for patterns and trends? Not many in today's environment. I saw the need to create a test to evaluate staff competency at my facility, but soon realized I would have no way of knowing if the results were good or bad. The only way to judge the results would be to have a standardized test that was used by multiple facilities. As president of the Houston X-ray Quality Society, I brought the topic up at a meeting in 1995, and a committee was set up to work on the test. The result is two competency tests--one for staff radiographers and one for mammographers--which are currently used by 35 to 40 facilities, with approximately 1,000 technologists taking the test each year. The tests include practical questions that reflect the knowledge required to perform daily exams. Each test has five sections that assess different areas of competency. The scoring system allows technologists to fail one or more individual sections but still pass the test overall. Twenty to 30 percent of the questions are new each year. That gives us the ability to look for improvement on previous year's questions, and at the same time, avoid producing a static and ineffective test. There are 60 questions on the staff radiographer test and 65 questions on the mammographer test, which also includes clinical images. Facilities must sign an agreement that states that they cannot use the test as a disciplinary tool in the employee's evaluation, or in any other way against the technologist. As a profession, radiology administration not only has regulatory requirements to evaluate competency, but also a moral duty to insure that patients receive the best possible care. We should not cover up or ignore the blemishes that we all know exist. Instead, we should take them on, as professional and personal challenges to improve the competency of our staff. PMID:11151318

    The big question being addressed on CTX during the past year has been: Why was energy confinement not improved by increasing the mesh flux conserver radius from 40 cm to 67 cm. A comparison of decaying spheromaks with the same values of j and n in the two cases shows tau/sub B/2 improving roughly as R/sup 2/ but little change in T/sub e/. As a result, <..beta..>/sub vol/ has gone from approx. 7.0% to approx. 2.0% and the inferred energy confinement time has remained unchanged at approx. 23 ..mu..s. An energy balance analysis of the 40 cm case showed that the observed rapid particle loss could account for most of the energy loss while providing a mechanism for the removal of impurities. At 67 cm, tau/sub p/ has also improved by about a factor of 2, particle loss therefore contributes substantially less to energy balance and the achievement in CTX of j/n/sub e/ as high as 3 x 10/sup -14/ A.m (I/sub tor/ up to 1 MA), low-Z impurities should not be a problem. A question then arises: Is CTX faced with a new strong energy loss mechanism that is characteristic of spheromaks in general. This question is not simply answered because it may involve processes of thermal conduction or convection that cannot be directly measured. In the following paragraphs we discuss many of the topics that have been considered in this search.

    This question is highly important. Indeed, high-dose cisplatin-based chemotherapy represents a curative option for patients with testicular germ cell tumors including seminoma and nonseminomas, namely embryonal carcinoma, yolk-sac tumor, teratoma, and choriocarcinoma. The curative effect is most likely due to large growth fractions in these solid and hematological tumors and probably high expression of protein target(s) of cisplatin. At least one such protein target of cisplatin was identified in species ranging from yeast to humans. These predictions could be easily verified.

    This is an outstanding and intellectually-stimulating question which introduces a new way to translate more effectively metastasis research to the clinic. It is certainly worth exploring and badly needed. because, if positive, drugs could be immediately useful to help defined populations of patients. Per points, we agree that these are limited metastasis groups; however, results could at minimum justify moving forward to full adjuvant trials. Worthy cause given the "bottleneck" we experience nowadays since drugs are mostly not tested in metastasis prevention.

    1995-01-01

    More than half of all cancer patients use some form of alternative treatment during the course of their illness. Alternative therapies are often started early in patients' illness, and their use is frequently not acknowledged to health care professionals. Some alternative therapies are harmful, and their promoters may be fraudulent. Persons who try alternative cancer therapies may not be poorly educated but may ultimately abandon conventional treatment. Recent attention has focused on aspects of questionable therapies that make these treatments attractive to patients and that may be perceived as being deficient in the practice of conventional health care professionals. Physicians with patients with cancer should always make sure that unproven therapies are discussed early in the therapeutic relationship. They should also attempt to be aware of alternative therapies that are in vogue in their particular geographic area. PMID:8533410

    With the blooming of online social media applications, Community Question Answering (CQA) services have become one of the most important online resources for information and knowledge seekers. A large number of high quality question and answer pairs have been accumulated, which allow users to not only share their knowledge with others, but also interact with each other. Accordingly, volumes of efforts have been taken to explore the questions and answers retrieval in CQA services so as to help users to finding the similar questions or the right answers. However, to our knowledge, less attention has been paid so far to question popularity in CQA. Question popularity can reflect the attention and interest of users. Hence, predicting question popularity can better capture the users' interest so as to improve the users' experience. Meanwhile, it can also promote the development of the community. In this paper, we investigate the problem of predicting question popularity in CQA. We first explore the factors that have impact on question popularity by employing statistical analysis. We then propose a supervised machine learning approach to model these factors for question popularity prediction. The experimental results show that our proposed approach can effectively distinguish the popular questions from unpopular ones in the Yahoo! Answers question and answer repository. PMID:24837851

    QA-by-Dossier-with-Constraints is a new approach to Question Answering whereby candidate answers ’ confidences are adjusted by asking auxiliary questions whose answers constrain the original answers. These constraints emerge naturally from the domain of interest, and enable application of real-world knowledge to QA. We show that our approach significantly improves system performance (75 % relative improvement in F-measure on select question types) and can create a “dossier ” of information about the subject matter in the original question.

    2012-01-01

    Over the last thirty years, many areas of expertise have developed in the pharmaceutical industry, from research and production to delivery to the patient. Strict European regulations and international best practice guidelines have shaped the expertise of pharmaceutical firms. Governments have set up health agencies to strengthen the supervision of private operators by recruiting in-house scientific experts and expert committees. The private and public sectors compete to recruit the best experts, and conflicts of interest must be addressed. The recent 'Mediator' (Benfluorex) case in France raises many questions about the potential failures of the health security system. Beyond the primary responsibility of the company, the main concern is off-label use. An effort to strengthen the legal framework and the tools used to collect, analyze and publicize pharmacovigilance data is currently underway at a national and European level. The competent authorities must restore public confidence through a more diligent and transparent handling of sensitive issues related to high-risk medicine. In a country where drug consumption is particularly high, doctors and pharmaceutical experts have been accused of becoming accustomed to risk and of loosing sight of the benefit to the patient. Health professionals in the private and public sectors must regain the appropriate health security reflexes to promote a more rational use of drugs. PMID:22730611

One particularly compelling area is the section that provides information on how the current administration of President George W. Bush has created a protocol for conducting such investigations. Another very useful section is titled â??Behind the Wireâ?ť and offers visitors an inside look into the U.S. Naval Base at Guantanamo Bay in Cuba. Perhaps the most moving and intense portion of the site is the discussion section, where visitors can leave feedback and read the impassioned opinions of others who have seen the program.

    A Question of Authority. This article deals with a certain scenario and several reviewers are to give their opinion. This one is in regards to - Suspending an IACUC approved animal use activity is about the last thing a research institution wants to do. Consider the predicament that the Great Eastern University IACUC faced when Dr. Janet Jenkins, the Attending Veterinarian, suspended all animal use activity on an approved protocol of Dr. Roy Maslo. Jenkins had the IACUCs authority to temporarily suspend a protocol, subject to review by a quorum of the full committee. She alleged that Maslo used mice from his breeding colony, not purchased rats, to begin a new study. Jenkins saw Maslos technicians bringing mouse cages to a procedure room and setting up for a minor survival surgery. She asked them to wait until she clarified things as she felt confident that the protocol called for rats. She called Maslo and asked him if the study had been approved for mice, to which he responded affirmatively. Still not feeling quite assured, she went to her office, reviewed the protocol, and found only rat studies described. She also called the IACUC office to see if there were any approved amendments which she may not have received, and was told that there were none. By the time she returned, one procedure was completed. Understandably upset, she informed the technicians and Maslo that any further activity on the protocol was suspended until the issue was resolved. Jenkins informed the IACUC chairman who in turned called an emergency meeting of the committee.

    Kahane, Guy

    2012-01-01

    Much seems to be at stake in metaphysical questions about, for example, God, free will or morality. One thing that could be at stake is the value of the universe we inhabit—how good or bad it is. We can think of competing philosophical positions as describing possibilities, ways the world might turn out to be, and to which value can be assigned. When, for example, people hope that God exists, or fear that we do not possess free will, they express attitudes towards these possibilities, attitudes that presuppose answers to questions about their comparative value. My aim in this paper is to distinguish these evaluative questions from related questions with which they can be confused, to identify structural constraints on their proper pursuit, and to address objections to their very coherence. Answers to such evaluative questions offer one measure of the importance of philosophical disputes. PMID:23024399

  8. The Value Question in Metaphysics.

    Much seems to be at stake in metaphysical questions about, for example, God, free will or morality. One thing that could be at stake is the value of the universe we inhabit-how good or bad it is. We can think of competing philosophical positions as describing possibilities, ways the world might turn out to be, and to which value can be assigned. When, for example, people hope that God exists, or fear that we do not possess free will, they express attitudes towards these possibilities, attitudes that presuppose answers to questions about their comparative value. My aim in this paper is to distinguish these evaluative questions from related questions with which they can be confused, to identify structural constraints on their proper pursuit, and to address objections to their very coherence. Answers to such evaluative questions offer one measure of the importance of philosophical disputes. PMID:23024399

  9. Henipaviruses-unanswered questions of lethal zoonoses.

    PubMed

    Field, Hume; Kung, Nina

    2011-12-01

    The highly lethal Hendra and Nipah viruses have been described for little more than a decade, yet within that time have been aetiologically associated with major livestock and human health impacts, albeit on a limited scale. Do these emerging pathogens pose a broader threat, or are they inconsequential 'viral chatter'. Given their lethality, and the evident multi-generational human-to-human transmission associated with Nipah virus in Bangladesh, it seems prudent to apply the precautionary principle. While much is known of their clinical, pathogenic and epidemiologic features in livestock species and humans, a number of fundamental questions regarding the relationship between the viruses, their natural fruit-bat host and the environment remain unanswered. In this paper, we pose and probe these questions in context, and offer perspectives based primarily on our experience with Hendra virus in Australia, augmented with Nipah virus parallels.

  19. Extraction of Questions Behind Messages

    NASA Astrophysics Data System (ADS)

    Matsumura, Naohiro; Kawahara, Daisuke; Okamoto, Masashi; Kurohashi, Sadao; Nishida, Toyoaki

    To overcome the limitation of conventional text-mining approaches in which frequent patterns of word occurrences are to be extracted to understand obvious user needs, this paper proposes an approach to extracting questions behind messages to understand potential user needs. We first extract characteristic case frames by comparing the case frames constructed from target messages with the ones from 25M sentences in the Web and 20M sentences in newspaper articles of 20 years. Then we extract questions behind messages by transforming the characteristic case frames into interrogative sentences based on new information and old information, i.e., replacing new information with WH-question words. The proposed approach is, in other words, a kind of classification of word occurrence pattern. Qualitative evaluations of our preliminary experiments suggest that extracted questions show problem consciousness and alternative solutions -- all of which help to understand potential user needs.

  1. The assessment of dyspnea during the vigorous intensity exercise by three Dyspnea Rating Scales in inactive medical personnel.

    PubMed

    Intarakamhang, Patrawut; Wangjongmeechaikul, Piyathida

    2013-11-01

    It is well recognized that exercise is good for health especially as it's known to prevent metabolic syndromes such as diabetes, hypertension and heart disease. To reap the benefits from exercise the most appropriate level of intensity must be determined, the level of intensity ranging from low, low to moderate to hard (vigorous). This study is aimed to 1. To investigate and evaluate 3 subjective rating scales. The Borg scale, the Combined Numerical Rating Scale (NRS) + FACES Dyspnea Rating Scale (FACES) and the Likert scale, during hard (vigorous) exercise. 2. To compare the effectiveness of the Borg scale and Combined Numerical Rating Scale (NRS) + FACES Dyspnea Rating Scale during the hard (vigorous) intensity exercise. This study uses a descriptive methodology. The sample group was 73 medical personnel that were leading an inactive life style, volunteers from Phramongkutklao Hospital. Participants were randomly divided into 3 groups. Group 1, those to report using the Borg Scale, group 2 using NRS + FACES, and group 3 to subjectively assess the intensity of the exercise using the Likert scale during a treadmill Exercise Stress Test (EST) using the Bruce protocol. The upper limit of the intensity in the study was equal to 85% of the maximal heart rate of all participants. The subjective reporting of the experienced level of dyspnea was undertaken immediately after the completion of exercise. The average age of participants was 23.37 years old. The 26 participants reporting using the Borg scale had mean Borg scale score of 13.46+1.77, a mode score of 15. The 24 participants reporting intensity levels through NRS +FACES had a mean NRS + FACES score of 6.83+1.09 and mode on the NRS + FACES scale equal to 7. The Likert scale group evaluated 23 participants with a mean Likert scale score of 2.74. That is those choosing Levels 2 and 3 were 6 (26.9%) and 17 participants (73.95%), respectively. Comparing the two groups with the Borg scale at equal to or greater than 15 and NRS + FACES greater than or equal to 7 using a Chi-square test showed that there were no statistical significant differences at p = 0.084. Using Spearman's rank correlation coefficient it was found that the subjective rating of intensity in the 3 different groups was not statistically significantly related to heart rate at 85% of maximal heart rate (P>0.05). NRS + FACES, the evaluation of the intensity of exercise at the hard (vigorous) level, was not statistically significantly different from the Borg scale. PMID:24171870

  3. Some open questions in hydrodynamics

    2014-12-16

    When speaking of unsolved problems in physics, this is surprising at first glance to discuss the case of fluid mechanics. However, there are many deep open questions that come with the theory of fluid mechanics. In this paper, we discuss some of them that we classify in two categories, the long term behavior of solutions of equations of hydrodynamics and the definition of initial (boundary) conditions. The first set of questions come with the non-relativistic theory based on the Navier-Stokes equations. Starting from smooth initial conditions, the purpose is to understand if solutions of Navier-Stokes equations remain smooth with the time evolution. Existence for just a finite time would imply the evolution of finite time singularities, which would have a major influence on the development of turbulent phenomena. The second set of questions come with the relativistic theory of hydrodynamics. There is an accumulating evidence that this theory may be relevant for the description of the medium created in high energy heavy-ion collisions. However, this is not clear that the fundamental hypotheses of hydrodynamics are valid in this context. Also, the determination of initial conditions remains questionable. The purpose of this paper is to explore some ideas related to these questions, both in the non-relativistic and relativistic limits of fluid mechanics. We believe that these ideas do not concern only the theory side but can also be useful for interpreting results from experimental measurements.

Do you think we’d get the same results if we asked this question in a different neighborhood? Start out by posing an open-ended question. Everyone writes answers on stick-on notes and sticks them on a large piece of paper. Explore ways to organize the responses to make sense of them. For instance, if the question is about languages, one approach is to put all the stick-on notes with the same language together. A further step could involve grouping related languages (Eastern European, Southeast Asian, etc.). Available as a web page or downloadable pdf.

One of the network's most recent programs (and this website which accompanies it), The Question of God, is certainly proof positive of this fact. The four-hour series (based on a popular Harvard course taught by Dr. Armand Nicholi) explores some of the basic questions of humanity, such as "What is happiness?" and "How do we find meaning and purpose in our lives?" The program itself does this by looking through the lens of the eyes of two of the 20th century's most well-known intellectuals, Sigmund Freud, who was a strong critic of religious belief, and C.S. Lewis, who was a strong proponent of "faith based on reason." On the site, visitors can learn about the lives of Freud and Lewis through excerpts from their own writings, read synopses of the programs, and read other perspectives on the question of God from such individuals as Oliver Wendell Holmes, Jr. and D.T. Suzuki. Additionally, visitors can watch clips from the program and listen in on roundtable conversations moderated by Dr. Nicholi.

    The internal consistency of the Human Behavior Rating Scale (HBRS) was investigated. The 91-item Likert-type scale is designed to measure five dimensions: persistence, curiosity, externalizing affect, internalizing affect, and cognition. It is used as a research tool to investigate the tenets of Eaves' 1993 integrated theory of human behavior. Three separate sampling plans were employed. Teachers and nonteachers completed Human Behavior Rating Scale ratings of children ranging in age from 5 to 18 years old. Cronbach coefficients alpha were reported by sex, grade, or age for the three samples. Of the 185 reported alpha coefficients, 175 were at or above .90, while 10 had values between .80 and .89.

    2004-10-03

    Given the range of fuel cycle goals and criteria, and the wide range of fuel cycle options, how can the set of options eventually be narrowed in a transparent and justifiable fashion? It is impractical to develop all options. We suggest an approach that starts by considering a range of goals for the Advanced Fuel Cycle Initiative (AFCI) and then posits seven questions, such as whether Cs and Sr isotopes should be separated from spent fuel and, if so, what should be done with them. For each question, we consider which of the goals may be relevant to eventually providing answers. The AFCI program has both ''outcome'' and ''process'' goals because it must address both waste already accumulating as well as completing the fuel cycle in connection with advanced nuclear power plant concepts. The outcome objectives are waste geologic repository capacity and cost, energy security and sustainability, proliferation resistance, fuel cycle economics, and safety. The process objectives are rea diness to proceed and adaptability and robustness in the face of uncertainties.

  20. Evaluative Conditioning: The “How” Question

    PubMed Central

    Jones, Christopher R.; Olson, Michael A.; Fazio, Russell H.

    2011-01-01

    Evaluative conditioning (EC) refers to attitude formation or change toward an object due to that object's mere co-occurrence with another valenced object or objects. This chapter focuses on the “how” question, that is, the question of what cognitive processes intervene between mere co-occurrence and attitude formation or change. Though EC has typically been thought of as occurring through a single, albeit contentious, mechanism, we begin by pointing out that both the heterogeneity of EC methodologies and the abundance of inconsistent results suggest that multiple processes with different characteristics can produce EC. We describe how the earliest posited process of EC, Pavlovian conditioning or signal learning, is a valid mechanism of EC that appears to have operated in some experiments but is unlikely to have operated in others and also cannot account for various EC findings. We describe other mechanisms of EC, when they can be expected to occur, and what characteristics they have. We particularly focus our attention on a process model of EC we have recently introduced, the implicit misattribution model. Finally, we describe the implications of a multi-process view of EC, which we argue can help resolve theoretical controversies and further the application of EC as a practical intervention for influencing attitudes in various domains.

  1. Les questions de migrations internationales

    Samman, Mouna Liliane

    1993-03-01

    International migrations have growing implications for both countries of origin and countries of destination. In the latter, the presence of foreigners and of members of their families today creates problems of integration, causes argument and brings mounting xenophobia. Paralleling political, economic and social measures taken by public authorities to respond to these difficulties, education needs to assist in defusing the resulting social tensions by preparing the minds of learners and helping to develop new attitudes. In particular, when educational programmes address questions of international migration, these should be treated in the framework of historical evolution so that their real significance and their true temporal and spatial dimensions become apparent. It is also important that the growing interdependence between countries should be made plain, that national history should be placed in its international context, and that the true consequences of these developments should be made clear. In this context, learners need to be acquainted with Human Rights, thereby stressing universal moral values and the role of the individual. Lastly, questions relating to international migration are usually presented in the media in a selective and partial manner, and the young people who take in this information often accept the hasty judgments which are made of situations as proven facts. This is why all teaching about international migration needs to be considered or reconsidered in the light of the complementary or competing actions of the media.

  2. The Urban Institute: Five Questions

    NSDL National Science Digital Library

    In the mid-1960s, President Johnson saw the need for independent nonpartisan analysis of the problems facing America's cities and their residents. The President created a blue-ribbon commission of civic leaders who recommended chartering a center to do that work and in 1968, the Urban Institute became that center. Today the Urban Institute analyzes policies, evaluates programs, and informs community development to "improve social, civic, and economic well-being." Working in all 50 states and abroad, the Institute shares its research with policymakers, business leaders, and academics. On this site, visitors can enjoy the Institute's series of interviews entitled "Five Questions For"" which poses five questions to the people behind the Urban Institute's research. Here, experts talk about the nature of their work and offer insights on what they've learned. The collection allows visitors to browse a chronological list of this series of interviews and each interview is easily emailed and is also available in a printer friendly format.

  3. Evaluation of four maternal smoking questions.

    Kharrazi, M; Epstein, D; Hopkins, B; Kreutzer, R; Doebbert, G; Hiatt, R; Swan, S; Eskenazi, B; Pirkle, J L; Bernert, J T

    1999-01-01

    OBJECTIVE: The authors evaluated four questions about maternal smoking during pregnancy for use on birth certificates. METHODS: Question 1 (yes/no format) and Question 2 (trimester-specific design) were tested among 1171 women who delivered at two Kaiser Permanente medical centers in northern California. Responses to Questions 1 and 2 were compared with smoking information provided by participants in telephone interviews conducted during pregnancy. Question 3 (multiple choice format) and Question 4 (month- and grouped month-specific design) were tested among 900 women who enrolled in a statewide prenatal screening program and who delivered in 20 hospitals in four Central Valley counties. Responses to Questions 3 and 4 were compared with mid-pregnancy serum cotinine levels. The authors evaluated the four questions in terms of conciseness, response rate, data accuracy, and type of data requested. RESULTS: Questions 1 and 2 were the most concise. Response rates could not be calculated for Questions 1 and 2. Response rates were 86.0% for Question 3 and 74.2% for Question 4. Sensitivity was 47.3% for Question 1, 62.1% for Question 2, 83.8% for Question 3, and 86.7% for Question 4. The types of data requested by Questions 2 and 4 seem to best satisfy the needs of the broad audience of birth certificate users. CONCLUSIONS: No single question was clearly superior. The authors propose a combination of Questions 2 and 4, which asks about average number of cigarettes smoked per day in the three months before pregnancy and in each trimester of pregnancy.

    Astronomy is not only a branch of science but also an important part of the culture and civilisations of peoples. Starting with archeoastronomy to the present day, it has always contributed to a better understanding of life, of humanity. After 400 years of modern astronomy, it still addresses major problems such as: Why there is something rather than nothing? Why is nature comprehensible to humans? How is cosmos related to humanity? Do multiverses exist? Is there life on other planets? Are we alone in the universe? Does the universe have a beginning? If so, what does it mean? How did the universe originate? All these questions are a challenge for interdisciplinary and transdisciplinary investigations, for philosophers, physicists, cosmologists, mathematicians, theologians. The new insights gained by pursuing in depth these common investigations will shape the society we live in and have important consequences on the future we are creating.

    1989-08-01

    As efforts gear up to map and sequence the human genome, increasing attention is being focused on the ethical, social and legal issues raised by the acquisition and use of genetic information. Several types of genetic screening carried out in a variety of settings hold enormous potential for improving health care. But such screening also poses an array of questions that are only now being addressed. Other applications of humanity's newfound and rapidly growing ability to peer into the genetic makeup of an individual also have serious implications. Use of so-called DNA fingerprinting, for instance, troubles some observers who question the reliability of such analyses carried out on a large scale and who worry about the effects on civil liberties of widespread genetic testing for identification purposes. The author discusses how genetic screening for medical purposes, though, seems to raise a broader array of difficult questions than do other uses of genetic information.

  19. Doctors' questions as displays of understanding.

    PubMed

    Deppermann, Arnulf; Spranz-Fogasy, Thomas

    2011-01-01

    Based on German data from history-taking in doctor-patient interaction, the paper shows that the three basic syntactic types of questions (questions fronted by a question-word (w-questions), verb-first (V1) questions, and declarative questions) provide different opportunities for displaying understanding in medical interaction. Each syntactic question-format is predominantly used in a different stage of topical sequences in history taking: w-questions presuppose less knowledge and are thus used to open up topical sequences; declarative questions are used to check already achieved understandings and to close topical sequences. Still, the expected scope of answers to yes/no-questions and to declarative questions is less restricted than previously thought. The paper focuses in detail on the doctors' use of formulations as declarative questions, which are designed to make patients elaborate on already established topics, giving more details or accounting for a confirmation. Formulations often involve a shift to psychological aspects of the illness. Although patients confirm doctors' empathetic formulations, they, however, regularly do not align with this shift, returning to the description of symptoms and to biomedical accounts instead. The study shows how displays of understanding are responded to not only in terms of correctness, but also (and more importantly) in terms of their relevance for further action. PMID:23264976

  20. The effect of Tomm's therapeutic questioning styles on therapeutic alliance: a clinical analog study.

    1998-01-01

    Tomm (1988) suggests that circular and reflexive questions tend to elicit feelings of freedom/acceptance whereas lineal and strategic questions usually trigger feelings of judgment/constraint. Employing an analog methodology, each of Tomm's four questioning styles was portrayed in the form of a 5-minute videotaped intake scenario. Forty family triads with a mother, father, and adolescent son were randomly assigned to one of four experimental conditions with ten families each. Each condition involved viewing one of four questioning style scenarios. All participants (N = 120 individuals--40 mothers, 40 fathers, and 40 adolescent sons) completed the Family Therapy Alliance Scale (FTAS; Pinsof & Catherall, 1986) and a validity-check instrument. The results indicated that circular and reflexive questioning styles elicited significantly higher (p < 0.001) alliance scores on the FTAS than did either lineal or strategic questions. Implications for the use of different types of questions in family therapy are discussed. PMID:9693949

  1. Ten questions about systems biology

    PubMed Central

    Joyner, Michael J; Pedersen, Bente K

    2011-01-01

    In this paper we raise ‘ten questions’ broadly related to ‘omics’, the term systems biology, and why the new biology has failed to deliver major therapeutic advances for many common diseases, especially diabetes and cardiovascular disease. We argue that a fundamentally narrow and reductionist perspective about the contribution of genes and genetic variants to disease is a key reason ‘omics’ has failed to deliver the anticipated breakthroughs. We then point out the critical utility of key concepts from physiology like homeostasis, regulated systems and redundancy as major intellectual tools to understand how whole animals adapt to the real world. We argue that a lack of fluency in these concepts is a major stumbling block for what has been narrowly defined as ‘systems biology’ by some of its leading advocates. We also point out that it is a failure of regulation at multiple levels that causes many common diseases. Finally, we attempt to integrate our critique of reductionism into a broader social framework about so-called translational research in specific and the root causes of common diseases in general. Throughout we offer ideas and suggestions that might be incorporated into the current biomedical environment to advance the understanding of disease through the perspective of physiology in conjunction with epidemiology as opposed to bottom-up reductionism alone.

  2. An Edge Question: What Now ?

    NSDL National Science Digital Library

    This feature from the nonprofit Edge Foundation, Inc. (reviewed previously in the July 25, 2000 Scout Report for Social Sciences & Humanities) is an impressive collection of thoughtful words in response to the recent terrorist attacks and ensuing war. The Edge postulated the question, "What now?" to its members with the idea that, as editor John Brockman explains, "within the community is invaluable expertise in many pertinent areas, not to mention the intelligence that the 'Edgies' can bring to the subjects." What separates this forum from many others dealing with recent issues of terrorism is that Brockman asks for "'hard-edge' comments, derived from empirical results or experience specific to the expertise of the contributors," rather than emotional or purely rhetorical responses. Here are a few of the pieces -- some essay length, others only a few sentences -- found here: psychiatrist Richard Rabkin takes a "strategic psychotherapy" approach to dealing with terrorism, science writer and television commentator Margaret Wertheim and archaeologist Timothy Taylor both touch on the corruption of science by weapons development as well as the intermingling of science and religion, and evolutionary scholar Richard Dawkins brings up the tendency to "bend over backwards to see the other point of view and blame ourselves for everything." Take time to peruse this collection of 44,000 words from 55 contributors and you'll be glad you did.

  7. A concept for major incident triage: full-scaled simulation feasibility study

    PubMed Central

    2010-01-01

    Background Efficient management of major incidents involves triage, treatment and transport. In the absence of a standardised interdisciplinary major incident management approach, the Norwegian Air Ambulance Foundation developed Interdisciplinary Emergency Service Cooperation Course (TAS). The TAS-program was established in 1998 and by 2009, approximately 15 500 emergency service professionals have participated in one of more than 500 no-cost courses. The TAS-triage concept is based on the established triage Sieve and Paediatric Triage Tape models but modified with slap-wrap reflective triage tags and paediatric triage stretchers. We evaluated the feasibility and accuracy of the TAS-triage concept in full-scale simulated major incidents. Methods The learners participated in two standardised bus crash simulations: without and with competence of TAS-triage and access to TAS-triage equipment. The instructors calculated triage accuracy and measured time consumption while the learners participated in a self-reported before-after study. Each question was scored on a 7-point Likert scale with points labelled "Did not work" (1) through "Worked excellent" (7). Results Among the 93 (85%) participating emergency service professionals, 48% confirmed the existence of a major incident triage system in their service, whereas 27% had access to triage tags. The simulations without TAS-triage resulted in a mean over- and undertriage of 12%. When TAS-Triage was used, no mistriage was found. The average time from "scene secured to all patients triaged" was 22 minutes (range 15-32) without TAS-triage vs. 10 minutes (range 5-21) with TAS-triage. The participants replied to "How did interdisciplinary cooperation of triage work?" with mean 4,9 (95% CI 4,7-5,2) before the course vs. mean 5,8 (95% CI 5,6-6,0) after the course, p < 0,001. Conclusions Our modified triage Sieve tool is feasible, time-efficient and accurate in allocating priority during simulated bus accidents and may serve as a candidate for a future national standard for major incident triage.

  8. Two-year-old children differentiate test questions from genuine questions.

    PubMed

    Grosse, Gerlind; Tomasello, Michael

    2012-01-01

    Children are frequently confronted with so-called 'test questions'. While genuine questions are requests for missing information, test questions ask for information obviously already known to the questioner. In this study we explored whether two-year-old children respond differentially to one and the same question used as either a genuine question or as a test question based on the situation (playful game versus serious task) and attitude (playful ostensive cues versus not). Results indicated that children responded to questions differently on the basis of the situation but not the expressed attitude of the questioner. Two-year-old children thus understand something of the very special communicative intentions behind test questions. PMID:21457590

  9. Consensus Conference Follow-up: Inter-rater Reliability Assessment of the Best Evidence in Emergency Medicine (BEEM) Rater Scale, a Medical Literature Rating Tool for Emergency Physicians

    PubMed Central

    Worster, Andrew; Kulasegaram, Kulamakan; Carpenter, Christopher R.; Vallera, Teresa; Upadhye, Suneel; Sherbino, Jonathan; Haynes, R. Brian

    2011-01-01

    Background Studies published in general and specialty medical journals have the potential to improve emergency medicine (EM) practice, but there can be delayed awareness of this evidence because emergency physicians (EPs) are unlikely to read most of these journals. Also, not all published studies are intended for or ready for clinical practice application. The authors developed “Best Evidence in Emergency Medicine” (BEEM) to ameliorate these problems by searching for, identifying, appraising, and translating potentially practice-changing studies for EPs. An initial step in the BEEM process is the BEEM rater scale, a novel tool for EPs to collectively evaluate the relative clinical relevance of EM-related studies found in more than 120 journals. The BEEM rater process was designed to serve as a clinical relevance filter to identify those studies with the greatest potential to affect EM practice. Therefore, only those studies identified by BEEM raters as having the highest clinical relevance are selected for the subsequent critical appraisal process and, if found methodologically sound, are promoted as the best evidence in EM. Objectives The primary objective was to measure inter-rater reliability (IRR) of the BEEM rater scale. Secondary objectives were to determine the minimum number of EP raters needed for the BEEM rater scale to achieve acceptable reliability and to compare performance of the scale against a previously published evidence rating system, the McMaster Online Rating of Evidence (MORE), in an EP population. Methods The authors electronically distributed the title, conclusion, and a PubMed link for 23 recently published studies related to EM to a volunteer group of 134 EPs. The volunteers answered two demographic questions and rated the articles using one of two randomly assigned seven-point Likert scales, the BEEM rater scale (n = 68) or the MORE scale (n = 66), over two separate administrations. The IRR of each scale was measured using generalizability theory. Results The IRR of the BEEM rater scale ranged between 0.90 (95% confidence interval [CI] = 0.86 to 0.93) to 0.92 (95% CI = 0.89 to 0.94) across administrations. Decision studies showed a minimum of 12 raters is required for acceptable reliability of the BEEM rater scale. The IRR of the MORE scale was 0.82 to 0.84. Conclusions The BEEM rater scale is a highly reliable, single-question tool for a small number of EPs to collectively rate the relative clinical relevance within the specialty of EM of recently published studies from a variety of medical journals. It compares favorably with the MORE system because it achieves a high IRR despite simply requiring raters to read each article’s title and conclusion. PMID:22092904

  10. How to... Ask the Right Questions

    Questions, questions, questions! They are a large part of a teacher's stock-in-trade. We use questions to help students review, to check on comprehension, to stimulate critical thinking, to encourage creativity, to emphasize a point, to control classroom activities, reduce disruptive behavior, to help determine grades, to encourage discussion, to discourage inattentiveness, and for other reasons and purposes. Questioning style and content varies from teacher to teacher, student group to student group, and situation to situation. The aim of this "How to?" booklet is to help you focus on a common teaching activity--the asking of questions. To illustrate some of the classifications and concepts discussed, excerpts from a videotaped lesson to third graders on magnetism appears at the end of this booklet.

  14. Doing Science and Asking Questions II: An Exercise That Generates Questions

    NASA Astrophysics Data System (ADS)

    Hurt Middlecamp, Catherine; Nickel, Anne-Marie L.

    2005-08-01

    Given the importance of questions in science, it is critical that students learn to ask questions as well as learning to answer them. This paper describes a classroom exercise to help students better ask their own questions. It has been classroom-tested in multiple formats and has also been used for curriculum development workshops for faculty. This exercise in creating questions can be easily customized to suit different instructional contexts; some variations are outlined. More broadly, this paper also discusses the pedagogical significance of questioning, raising four salient points: (1) learners are more likely to have a personal interest in the questions they raise; (2) questions can serve as entry points for issues relating to ethnicity and gender; (3) questions give control to the person who asks them; and (4) questions can challenge existing structures, categories, and norms.

  5. Term weighting schemes for question categorization.

    PubMed

    Quan, Xiaojun; Liu, Wenyin; Qiu, Bite

    2011-05-01

    Term weighting has proven to be an effective way to improve the performance of text categorization. Very recently, with the development of user-interactive question answering or community question answering, there has emerged a need to accurately categorize questions into predefined categories. However, as a question is usually a piece of short text, can the existing term-weighting methods perform consistently in question categorization as they do in text categorization? The answer is not clear, since to the best of our knowledge, we have not seen any work related to this problem despite of its significance. In this study, we investigate the popular unsupervised and supervised term-weighting methods for question categorization. At the same time, we propose three new supervised term-weighting methods, namely, qf*icf, iqf*qf*icf, and vrf. Comparisons of them with existing unsupervised and supervised term-weighting methods are made through a series of experiments on question collections of Yahoo! Answers. The experimental results show that iqf*qf*icf achieves the best performance among all term-weighting methods, while qf*icf and vrf are also competitive for question categorization. Meanwhile, tf*OR is proven to be the most significant one among existing methods. In addition, iqf*qf*icf and vrf are also effective for long document categorization. PMID:20733219

  18. Development of a scale to measure individuals’ ratings of peace

    PubMed Central

    2014-01-01

    Background The evolving concept of peace-building and the interplay between peace and health is examined in many venues, including at the World Health Assembly. However, without a metric to determine effectiveness of intervention programs all efforts are prone to subjective assessment. This paper develops a psychometric index that lays the foundation for measuring community peace stemming from intervention programs. Methods After developing a working definition of ‘peace’ and delineating a Peace Evaluation Across Cultures and Environments (PEACE) scale with seven constructs comprised of 71 items, a beta version of the index was pilot-tested. Two hundred and fifty subjects in three sites in the U.S. were studied using a five-point Likert scale to evaluate the psychometric functioning of the PEACE scale. Known groups validation was performed using the SOS-10. In addition, test-retest reliability was performed on 20 subjects. Results The preliminary data demonstrated that the scale has acceptable psychometric properties for measuring an individual’s level of peacefulness. The study also provides reliability and validity data for the scale. The data demonstrated internal consistency, correlation between data and psychological well-being, and test-retest reliability. Conclusions The PEACE scale may serve as a novel assessment tool in the health sector and be valuable in monitoring and evaluating the peace-building impact of health initiatives in conflict-affected regions.

  19. Relationship between perceived and actual frequency represented by common rating scale labels.

    PubMed

    Woltz, Dan J; Gardner, Michael K; Kircher, John C; Burrow-Sanchez, Jason J

    2012-12-01

    Two experiments investigated the relationship between subjective interpretation of frequency terms and corresponding objective values. Evidence supported the existence of a nonlinear relationship that is well described by a logarithmic function. The general form of this relationship was consistent across different methods of eliciting subjective frequency estimates and different frequency response scales. These findings, in combination with prior research, suggest that individuals can be highly accurate in reporting the frequency of prior experiences but that subjective reports using common frequency response scales and scoring methods should not be taken to reflect equal intervals of actual frequency. This bears similarity to psychophysical relationships observed between sensation and stimulus intensity, and it has implications for the interpretation and analysis of self-report measures that use Likert-type frequency response scales.

  5. A topic clustering approach to finding similar questions from large question and answer archives.

    PubMed

    Zhang, Wei-Nan; Liu, Ting; Yang, Yang; Cao, Liujuan; Zhang, Yu; Ji, Rongrong

    2014-01-01

    With the blooming of Web 2.0, Community Question Answering (CQA) services such as Yahoo! Answers (http://answers.yahoo.com), WikiAnswer (http://wiki.answers.com), and Baidu Zhidao (http://zhidao.baidu.com), etc., have emerged as alternatives for knowledge and information acquisition. Over time, a large number of question and answer (Q&A) pairs with high quality devoted by human intelligence have been accumulated as a comprehensive knowledge base. Unlike the search engines, which return long lists of results, searching in the CQA services can obtain the correct answers to the question queries by automatically finding similar questions that have already been answered by other users. Hence, it greatly improves the efficiency of the online information retrieval. However, given a question query, finding the similar and well-answered questions is a non-trivial task. The main challenge is the word mismatch between question query (query) and candidate question for retrieval (question). To investigate this problem, in this study, we capture the word semantic similarity between query and question by introducing the topic modeling approach. We then propose an unsupervised machine-learning approach to finding similar questions on CQA Q&A archives. The experimental results show that our proposed approach significantly outperforms the state-of-the-art methods. PMID:24595052

    2012-11-13

    This work answers the basic questions of superconductivity in a question-and-answer format. We extend a basic hypothesis to various superconductors. This hypothesis is that superconductivity requires that the pairing gap locates around the Fermi level. On the basis of this hypothesis our calculations give the so-called three factor theory with which some key problems of the high temperature superconductivity are explained.

    This activity is a two-part (three week) lab in which students initially develop a claim (non-scientific) and learn how to use evidence to support a claim. They then are provided with a scientific research question for which they need to make a claim supported with evidence from their own models (river/stream tables). Based on their results, they then ask a new research question, design the model, carry out their tests and report their results.

  11. From Question Answering to Visual Exploration

    SciTech Connect

    McColgin, Dave W.; Gregory, Michelle L.; Hetzler, Elizabeth G.; Turner, Alan E.

    2006-08-11

    Research in Question Answering has focused on the quality of information retrieval or extraction using the metrics of precision and recall to judge success; these metrics drive toward finding the specific best answer(s) and are best supportive of a lookup type of search. These do not address the opportunity that users? natural language questions present for exploratory interactions. In this paper, we present an integrated Question Answering environment that combines a visual analytics tool for unstructured text and a state-of-the-art query expansion tool designed to compliment the cognitive processes associated with an information analysts work flow. Analysts are seldom looking for factoid answers to simple questions; their information needs are much more complex in that they may be interested in patterns of answers over time, conflicting information, and even related non-answer data may be critical to learning about a problem or reaching prudent conclusions. In our visual analytics tool, questions result in a comprehensive answer space that allows users to explore the variety within the answers and spot related information in the rest of the data. The exploratory nature of the dialog between the user and this system requires tailored evaluation methods that better address the evolving user goals and counter cognitive biases inherent to exploratory search tasks.

  12. Cognitive and emotional reactions to questions in the Comparison Question Test.

    PubMed

    MacNeill, A Luke; Bradley, M T; Cullen, M C; Arsenault, Andrea M

    2014-04-01

    The effect of situational factors on perceptions of items on the polygraph Comparison Question Test (CQT) was assessed. In an initial experiment, 86 students (30 men, 56 women; M age = 20.3 yr., SD = 4.0) imagined one of eight scenarios that varied by guilt or innocence, the commission of a real crime or mock crime, and interrogation by a police officer or a professor. They then rated generic CQT questions for importance and emotional concern. All participants rated crime-relevant questions as being more important than past-crime comparison questions. "Guilty" participants also rated these questions as being more emotionally concerning, but "innocent" participants showed no differences in their ratings of concern for the two question types. Interrogator or crime type did not affect the general pattern of responding. A second experiment involving 80 students (21 men, 58 women, 1 non-specified; M age = 22.5 yr., SD = 7.3) replaced the generic CQT questions with content-specific questions developed by the participant. Those imagining guilt showed no differencesin their ratings of relevant and comparison questions, whereas those imagining innocence rated comparison questions as more concerning. Again, interrogator type and crime type had little effect on results. Overall these findings indicated distinctions in cognitive and emotional appraisal for CQT questions, with the nature of emotional concern dependent on guilt/innocence status and the personal relevance of comparison questions. Evidence suggests that the CQT is robust to other situational factors, such as crime type and interrogator type. PMID:24897878

    If scientific inquiry is to be part of the focus in secondary school science, teachers must develop learning situations in which question posing is essential and they must help students learn how to pose scientifically oriented questions. In focusing on questions, teachers and students both play an important role the classroom. Teachers provide rich inquiry-based opportunities for students, while students engage in exploring the phenomena they encounter in class.

    Navarro, P. [Univ. of California, Irvine, CA (United States)] [Univ. of California, Irvine, CA (United States)

    1996-08-01

    In the terra incognita of restructuring, there are no adequate guidebooks. There are, however, a handful of questions that all stakeholders should address if the many restructuring debates are to be intelligently advanced. As the regulators consider signing on to this brave new world of electricity restructuring, it is becoming increasingly clear that there is no adequate guidebook. The purpose of this article is to help fill this gap by examining 10 key questions in the debate. Those questions are: Is the generation market potentially competitive? Is the market for electricity generation currently concentrated? Spot market power exchange vs. direct access - how should the transmission pool be structured? Should PBR be substituted for RBR in the distribution market? Can small residential customers be protected from price discrimination? Should utilities be allowed full recovery of stranded costs? How should stranded costs be valued? How should stranded costs be recovered? What about demand-side management and integrated resource planning? What about ratepayer assistance programs?
